Seeing Previously Invisible Molecules For The First Time

2009-10-25T10:12:00.000-07:00

A team of Harvard chemists led by X. Sunney Xie has developed a new microscopic technique for seeing, in color, molecules with undetectable fluorescence. The room-temperature technique allows researchers to identify previously unseen molecules in living organisms and offers broad applications in biomedical imaging and research.
he scientists' results are published in the Oct. 22 issue of Nature. Partial funding for the project was provided by the National Science Foundation (NSF).
Fluorescence is a phenomenon in which an electron in a molecule absorbs energy from light and moves to a higher energy level or excited state. The energy of the light is contained in a unit called a photon.

HD VMD - 40GB Multilayer Optical disc - It Costs a fraction of Blu Ray !!

2006-12-09T17:47:00.000-08:00

The developer of a maverick high-density DVD format is planning to release a player that costs a fraction of the price of devices using the mainstream Blu-ray and HD-DVD formats.

London-based New Media Enterprises announced its Versatile Multi-layer Disc (VMD) format at Cebit earlier this year. It uses low-cost red lasers used in existing DVD players but, as its name suggests, can squeeze up to 40GB on a single disc by stacking the data at different levels. The player, launched at the Mipcom digital-content show in Cannes, will cost about $175 (£95), which compares very favourably with the competing formats.

Samsung’s BD-P1000 Blu-ray player has already debuted in the UK with a £1,000 price tag. Toshiba expects to have its HD-DVD players on the market in November and December, with the HD-E1 and HD-XE1 models costing €599 (around £400) and €899 (around £600) respectively.

However, New Media Enterprises’ product seems unlikely to dent the market for Blu-ray and HD-DVD players, because deals have already been signed with major Hollywood and European companies to sell titles in those formats. New Media Enterprises said at Cebit that it would initially target the Chinese and Bollywood markets – the latter, in particular, is very big in Britain. A spokeswoman for the company said that other content providers had shown interest and a deal with one German company is expected to be announced shortly. New Media Enterprises’ player will be available in some European countries in December, with availability throughout Europe in January.

Massive Array of Idle Disks-MAID

2006-11-29T17:32:00.000-08:00

MAID is an array of hard drives combined to work as a single point of storage. Scalability is therefore not an issue. At present the smallest of the Copan's available systems is 28 terabytes, nad the largest is 200 terabytes. The space used by the largest capacity array that Copan produces is just one suare metre, thus saving hume amount of space.
MAID will be used where there is a need to archive large amount of data scaling up in terabytes. It also provides quick access to large amount of data.
MAID consumes less power and hence produces less heat. This is possible becoz, when data is not accessed the harddisks go into idle mode thus making it more energy efficient. MAID allows the data storage in structured formats like SQL, MS Access and also in unstructured data formats like Word and Powerpoint.

This technology when becomes more dominant will soon replace the present hosting servers with lots of features and also we can find most of the data warehouse shifting to this new technology.

Prototype DNA computer ( MAYA-II)

2006-10-23T19:48:00.000-07:00

Researchers say that they have developed a DNA-based computer that could lead to faster, more accurate tests for diagnosing West Nile Virus and bird flu. Representing the first “medium-scale integrated molecular circuit,” it is the most powerful computing device of its type to date, they say.

The new technology could be used in the future, perhaps in 5 to 10 years, to develop instruments that can simultaneously diagnose and treat cancer, diabetes or other diseases, according to a team of scientists at Columbia University Medical Center in New York and the University of New Mexico, Albuquerque. Their study is scheduled to appear in the November issue of the American Chemical Society’s Nano Letters, a monthly peer-reviewed journal.

“These DNA computers won’t compete with silicon computing in terms of speed, but their advantage is that they can be used in fluids, such as a sample of blood or in the body, and make decisions at the level of a single cell,” says the researcher, whose work is funded by the National Science Foundation.
Composed of more than 100 DNA circuits, MAYA-II is quadruple the size of its predecessor, MAYA-I, a similar DNA-based computer developed by the research team three-years ago. With limited moves, the first MAYA could only play an incomplete game of tic-tac-toe, the researcher says.

The experimental device looks nothing like today’s high-tech gaming consoles. MAYA-II consists of nine cell-culture wells arranged in a pattern that resembles a tic-tac-toe grid. Each well contains a solution of DNA material that is coded with “red” or “green” fluorescent dye.

The computer always makes the first move by activating the center well. Instead of using buttons or joysticks, a human player makes a “move” by adding a DNA sequence corresponding to their move in the eight remaining wells. The well chosen for the move by the human player responds by fluorescing green, indicating a match to the player’s DNA input. The move also triggers the computer to make a strategic counter-move in one of the remaining wells, which fluoresces red. The game play continues until the computer eventually wins, as it is pre-programmed to do, Macdonald says. Each move takes about 30 minutes, she says.

80 core processor !!!

2006-10-04T02:20:00.000-07:00

On Tuesday, Intel showed off an 80-core processor at its developer forum taking place in San Francisco this week and one of the prominent features of the chip is that each core is connected directly to a 256MB memory chip through a technology called Through Silicon Vias, or TSV.

The memory wedded to the processor cores could constitute the entire memory needed for a computer, Intel CTO Justin Rattner told News.com in an interview during the Intel Developer Forum. TSV could be used in a variety of chips, not just the 80-core monster. As a result, computer makers, when building a system, would get their memory when they bought their processors from Intel. They would not have to obtain memory chips separately from other companies like they do now.

Wedding memory directly to the processor would have huge performance benefits. Currently, memory and the processor in Intel-based computers exchange data through a memory controller, which moves at a far slower rate than the processor. It's one of the big bottlenecks in computer performance. TSV, which displaces the memory controller, would shuttle data far quicker.

Data coming out of memory also squeezes through an overcrowded port. TSV would effectively open up thousands of ports. Overall, Rattner said, TSV is by far a more notable accomplishment than putting 80 cores on the same piece of silicon.

The processor cores are not restricted to getting memory from the chip wedded to it, added Rattner. The cores are connected to each other through high-speed links controlled by a router integrated into each core.

Overall, the prototype 80-core chip has an aggregate memory bandwidth of 1 terabyte per second, meaning that it can shift a trillion bytes per second.

Conceivably, TSV would also put AMD on the hot seat. A good portion of the performance gains AMD achieved with the Opteron chip came from Opteron's integrated memory controller. Intel does not put integrated memory controllers on its chips.

Rattner, however, noted that implementing TSV will take time. The memory chips attached to the 80-core processor are SRAM, a relatively expensive memory that Intel still makes. The next step is to see how well DRAM works with TSV.

Engineers would also have to devise packages that would let the processor and memory live together. The processor typically generates more heat than the memory, which is one of the factors that would have to be considered. Although it doesn't get many headlines, packaging design is a huge challenge for chipmakers.

"It's still in the research stage," he said. "We will do a lot of work with it in the next several years."

Phase-change Random Access Memory (PRAM)

2006-09-17T04:16:00.000-07:00

The Phase-change Random Access Memory (PRAM) is more scalable than any other memory architecture being researched and features the fast processing speed of RAM for its operating functions combined with the non-volatile features of flash memory for storage.

A key advantage in PRAM is its extremely fast performance. Because PRAM can rewrite data without having to first erase data previously accumulated, it is effectively 30-times faster than conventional flash memory. Incredibly durable, PRAM is also expected to have at least 10-times the life span of flash memory.

PRAM will be a highly competitive choice over NOR flash, available beginning sometime in 2008. Samsung designed the cell size of its PRAM to be only half the size of NOR flash. Moreover, it requires 20 percent fewer process steps to produce than those used in the manufacturing of NOR flash memory.

Samsung’s new PRAM was developed by adopting the use of vertical diodes with the three–dimensional transistor structure that it now uses to produce DRAM. The new PRAM has the smallest 0.0467um 2 cell size of any working memory that is free of inter-cell noise, allowing virtually unlimited scalability.

The Korean company announced that it has completed the first working prototype of what is expected to be the main memory device to replace high density NOR flash within the next decade. Adoption of PRAM is expected to be especially popular in the future designs of multi-function handsets and for other mobile applications, where faster speeds translate into immediately noticeable boosts in performance. High-density versions will be produced first, starting with 512 Mb.

THERMOPHOTOVOLTAIC ELECTRIC POWER GENERATION USING EXHAUST HEAT

2006-08-30T01:12:00.000-07:00

Furnaces in the glass, metalcasting, and steel industries operate at very high
temperatures and lose tremendous amounts of energy in their exhaust streams.
With the emissions-reducing shift to gas-oxy furnaces in these industries,
exhaust temperatures are climbing even higher. Waste heat from furnaces in
the glass, metalcasting, and steel industries is usually vented to the atmosphere.
In some facilities, it must be diluted with cool air to reduce its temperature prior
to venting. Until now, the venting of this waste heat has represented the loss of
a valuable resource.
A new technology adds value to this waste stream by using exhaust heat to
generate hundreds of kilowatts of electricity. This unique innovation uses new
infrared-sensitive photovoltaic cells mounted inside ceramic tubes. These tubes
are heated in the exhaust stream of an industrial process and radiate energy
inward to the photovoltaic cells to generate electricity directly from the waste
heat. The energy density in these systems is over 100 times that of solar energy,
producing over 100 times the energy of conventional photovoltaic or solar cells.

Economics and Commercial Potential
Exhaust heat offers an attractive energy alternative to the glass, metalcasting, and steel
industries. In particular, JX Crystals, Inc., has targeted the glass industry because of
an estimated 67 MW of year-round electrical generation available in this industry alone.
The technology has already attracted the partnership of a major glass-industry player
interested in demonstrating the technology on a glass furnace.
Given additional investment in the business and a market volume well over 10 MW per
year, JX Crystals, Inc., estimates the thermophotovoltaic circuit to cost approximately
$0.20 per watt. Balance of system costs are estimated to be $0.50 per watt. Assuming
a price of $1 per watt, utility rates of $0.05 per kWh, and a duty cycle of 90%, the
payback period should be less than 3 years.
This technology could save 27 billion Btu of electricity per installed unit each year. First
sales for the technology are expected by 2004. Based on 25% market penetration by
2010, annual savings could be 0.5 trillion Btu with 18 units installed, each containing 200
5-kW tubes. Market penetration of 50% by 2020 could save 1.0 trillion Btu from the
operation of 37 units by the glass industry.

Magnetoresistive RAM - MRAM

2006-08-20T21:42:00.000-07:00

Semiconductor giant Freescale has started selling the next generation of memory, called MRAM, becoming the first company to produce the technology with potential useability in many of today's upcoming devices.

MRAM stands for magnetoresistive random access memory and it differs from conventional RAM in that information is stored using magnetic properties, instead of an electronic charge. This means the chips can store information once the power has been switched off.

The RAM is capable of read/write times of only 35-nanoseconds as opposed to 50-70-ns offered by DRAM. Freescale are currently only selling the units in 4Mbit capacities, though now the ice has been broken the technology should flourish and larger capacities will hopefully soon be on the way.

Analyst Will Strauss from the research firm Forward Concepts said: "This is radically new technology. People have been dabbling in this for years, but nobody has been able to make it in volume."

"This is the most significant memory introduction in this decade."

The technology can challenge both conventional RAM as well as flash memory, a market that has only taken-off over the last few years as more and more people buy memory sticks, MP3 players and portable storage cards. Unlike flash memory MRAM doesn't degrade over time, and has faster read/write times.

Experts also predict that MRAM could one day be used to store whole operating systems, boosting the start-up times of tomorrow's PCs. It seems the perfect candidate to replace today's technology as it is smaller, cheaper and faster than anything on the market at present.

The 4Mbit chips will go on sale for $25 each, and Freescale has announced it already has (unnamed) customers.

Quickly Erase Hard Drives

2006-06-30T03:14:00.000-07:00

What if we can erase Hard drives in seconds?

Scientists at the Georgia Institute of Technology (Atlanta), working with L-3 Communications Corp. (New York), said they have developed a technique for quickly erasing hard-disk drives. The team reports development of a prototype fast-erasure system to prevent sensitive information from reaching enemy eyes.

At the time of the U.S.-China incident, there was no way the U.S. crew could quickly erase hard drives on the surveillance aircraft before landing on Chinese soil. The Chinese eventually gained access to U.S. military secrets.

Erasing a hard drive usually takes hours using special procedures that repeatedly scramble information on a disk drive. Still, given unlimited resources and time, special magnetic snooping techniques can often recover at least some of the original information.

The researchers sought a method that not only securely erased information but also performed the erasure during emergency situations where minutes, not hours, were available.

The researchers concluded that permanent magnets are the best solution. Other methods, including burning disks with heat-generating thermite, crushing drives in presses, chemically destroying the media or frying them with microwaves all proved susceptible to sensitive, patient, recovery efforts.

Permanent magnets for erasing magnetic media have been available since the dawn of disk drives, but the team found that commercial systems were either magnetically too weak, too large and heavy or could not meet air-safety standards. Instead, the team crafted a new generation of super-powerful magnets to penetrate hard disk enclosures to quickly erase magnetic media. Special high-strength magnets as powerful as those in medical imaging equipment proved sufficient for permanently erasing all information on a disk drive in a single pass.

To create a magnetic field strong enough to penetrate the metal housing around a disk drive and erase the magnetic media inside, the researchers designed a neodymium iron-boron magnet with special pole pieces made of esoteric cobalt alloys. A motorized mechanism pushed disk drives past the magnets; a back up twist-knob allows operators to manually pull drives through the magnetic field.

The 125-pound prototype is being streamlined into a deployable version that is light enough for aircraft, operates independently of aircraft electrical systems, produces no noxious gases or flames and includes fail-safe procedures to prevent inadvertent erasures. The team verified that it was impossible to recover information from disk drives erased with the permanent magnets. They used a magnetic force microscope to map even the smallest magnetic domains on the surface of an erased disk drive to ensure that the patterns found there were completely random.

The team claimed the magnetic eraser could also be used for commercial applications like quickly erasing VHS tapes, floppy drives, data cassettes and hard drives.

"Conroe" and "Merom" get a name and a birthday

Intel has just passed us word about a new branding decision for the upcoming second generation Core processors. Intel's first generation desktop Core processor, Conroe, will carry the moniker Core 2 Duo, suplementing the 65nm Netburst Presler micro-architecture. Notebook processors, earlier dubbed Merom, will also carry the Core 2 Duo moniker even though the processors are very different than the desktop Core 2 Duo chips. The highest end desktop processors, previously named Extreme Edition, will be labeled as Core 2 Extreme opposed to the mainstream Core 2 Duo.

Core 2 Extreme will actually become the first Conroe processor to launch, followed immediately by Core 2 Duo E6700 -- as outlined by Intel's most recent desktop roadmap. Merom and Conroe are both based on 65nm process designs with shared L2 cache and aggressive power management. Conroe and Merom will both be backwards compatible with recently manufactured desktop and mobile motherboards.

Intel's most recent forward outlook confirms Conroe will ship in July, 2006 followed shortly by Merom in August 2006. This was hinted by Intel CEO Paul Otellini earlier this week during the company's quarterly report. Intel's press release about the new branding claims:

Consumers and businesses will also be able to purchase these processors as part of Intel’s market-focused platforms -- a collection of Intel hardware and software technology innovation that is designed and tested together and tailored to specific computing needs. Intel offers wireless computing, in-home entertainment or business productivity platforms through the company’s Intel Centrino Duo mobile technology, Intel Viiv technology and Intel vPro.

Intel is expected to publicly demonstrate Core 2 Duo at Computex 2006 in Taipei, Taiwan on June 6th, 2006. AMD is expected to launch its next generation DDR2 desktop component

Microsoft support for Windows 98, ME to end in July

2006-04-17T06:32:00.000-07:00

Windows 98, Windows 98 Second Edition (SE) and Windows Millennium Edition (ME) are nearing the end of their support from Microsoft Corp.

The software vendor will stop supporting these operating system editions on July 11, according to information on its Web site.

On that date, all public and technical support for the products will be suspended, and Microsoft also will stop security updates for the operating systems, the company said. However, online self-help support will be available on Microsoft's support Web site until at least July 11, 2007.

Microsoft says the operating systems are "outdated" and pose security risks to customers, which is why it is ending support for them, according to its Web site. Microsoft recommends that customers still running them upgrade to newer versions of Windows, such as Windows XP, as soon as possible.

Multivitamin

2006-03-04T02:07:00.000-08:00

To work out your own personal nutritional programme can be difficult, but it would probably be impossible to buy the individual nutrients separately.

This is where a multiple formula can help a lot. Although individual nutritional needs are all different, certain groups of people often share common nutritional requirements.

They are likely to be subject to similar conditions in their daily lives, which may influence nutrient intake. Our nutritionists/scientific/medical consultants have formulated the various Discovery Health formulas to suit the needs of a large number of different groups of people.

Many people choose to use a multiple formula as the mainstay of a supplement programme, adding other nutrients if they wish.

Food Base Multivitamin and mineral formula

This careful blend of vitamins and minerals has been formulated for anyone looking for a broad spectrum of vitamins and minerals in a single formula. All the important antioxidant nutrients, Beta Carotene (the safer precursor form of Vitamin A), Vitamin C and Vitamin E are included at good levels, as well as a broad range of trace minerals.

New Treatments for Acute Leukemia

2006-02-09T23:59:00.000-08:00

Acute lukemia is a hematopoietic progenitor cell malignancy. These cells proliferate in an uncontrolled fashion and ultimately replace normal bone marrow elements. Most cases arise with no clear cause. However, radiation and some toxins (benzene) are clearly leukemogenic. In addition, a number of chemotherapeutic agents (especially procarbazine, melphalan, other alkylating agents, and etoposide).

Most of the clinical findings in acute lukemia are due to bone marrow failure, which results from replacement of normal bone marrow elements by the malignant cell. Less common manifestations include direct organ infiltration (skin, gastrointestinal tract, meninges).

Acute lymphoblastic lukemia (ALL) comprises 80% of the acute lukemias of childhood. The peak incidence is between 3 and 7 years of age. However, ALL is also seen in adults and comprises approximately 20% of adult acute lukemias. Acute myelogenous lukemia (AML; acute nonlymphocytic lukemia [ANLL]) is chiefly an adult disease.
Clinical Findings

A. Symptoms and Signs: Most patients with acute leukemia present with an acute illness and have been ill only for days or weeks. Bleeding (usually due to thrombocytopenia) is usually in the skin and mucosal surfaces, manifested as gingival bleeding, epistaxis, or menorrhagia. Less commonly, widespread severe bleeding is seen.
Treatment
Most young patients with acute leukemia are treated with the objective of effecting a cure. The first step in treatment is to obtain complete remission.
Acute myelogenous lukemia is treated initially with intensive combination chemotherapy, including daunorubicin and cytarabine. Effective treatment produces aplasia of the bone marrow, which takes 2B3 weeks to recover. During this period, intensive supportive care, including transfusion and antibiotic therapy, is required. Once complete remission has been achieved, several different types of postremission therapy are potentially curative. Options include repeated intensive chemotherapy, high-dose chemoradiotherapy with allogeneic bone marrow transplantation, and high-dose chemotherapy with autologous bone marrow transplantation. Recently, progress has been made in the treatment of acute promyelocytic leukemia (M3). The addition of all-trans retinoic acid to initial chemotherapy has improved the results of both initial treatment and long-term survival.
Acute lymphoblastic leukemia is treated initially with combination chemotherapy, including daunorubicin, vincristine, prednisone, and asparaginase.
Chronic Lymphocytic Leukemia
Chronic lymphocytic leukemia (CLL) a B lymphocyte (rarely T lymphocytes) clonal malignancy. The disease is usually indolent, with slowly progressive accumulation of long-lived small lymphocytes. These cells are immunoincompetent.

Chronic lymphocytic leukemia is manifested clinically by immunosuppression, bone marrow failure, and organ infiltration with lymphocytes. Immunosuppression, bone marrow failure, and infiltration of organs.

Clinical Findings
A. Symptoms and Signs: Chronic lymphocytic leukemia is a disease of the elderly, with 90% of cases occurring after age 50 and a median age at presentation of 65. Many patients will be incidentally discovered to have lymphocytosis.
Treatment
Most cases of early indolent chronic lymphocytic lukemia require no specific therapy. Indications for treatment include progressive fatigue, troublesome lymphadenopathy, or the development of anemia or thrombocytopenia. These patients have either symptomatic and progressive stage II disease or stage III/IV disease. Initial therapy is with chlorambucil, 0.6B1 mg orally every 3 weeks. Complications such as autoimmune hemolytic anemia or immune thrombocytopenia may be treated with high-dose prednisone but Fludarabine is a new agent which is useful in treating disease refractory to The with aggressive disease may be a candidate for allogeneic bone marrow transplantation

Genomic nanoprocessors

2006-02-01T03:05:00.000-08:00

The interface of genomics and electronic engineering research is an exciting new area which promises to yield imaginative approaches to the development of medical devices and diagnostics. DNA molecules have found use as combinatorial computers, proto-transistors and semi-conductors amongst other things. However, the potential for integrating together, on a single semiconductor device, biomolecule-based equivalents of electronics circuit elements is untapped at present.

Future Deliverable
The potential position of leadership which could be created for the UK with respect to exploitation of genomics-based technologies

The core scientific understanding and technology underlying this radical vision are being addressed through the Beacon Project being undertaken by Professor Peter Ghazal and colleagues at the University of Edinburgh. Four leading centres of expertise in biotechnology, electronic engineering, chemistry and physics have been brought together to develop a platform technology in genomic nanoprocessors.

Early Achievement
Scottish Enterprise is funding an industrial PhD studentship to facilitate a collaboration with a Scottish microelectronics company.

Healthcare Deliverables

* a radical new vision of future healthcare, known as ‘bio-intelligent medication’
* nano-scale devices administered in vivo to detect and prevent disease.

The team is investigating technology based upon the idea of using DNA molecules, anchored to a silicon substrate, which switch between two configurations in response to electronic and biochemical signals, in a way that mimics transistor-like behaviour. A key innovative feature of the project will be the integration of these devices within digital circuitry to provide on-chip intelligence (sensing, logic and read/write elements for example) for local data processing.

IPR
A core project patent covering fundamental aspects of the work has been submitted and will be published in Spring 2004.

Potential Applications for the hybrid ‘DNA on silicon’ processors

* Medical Devices
* Diagnostics

The long-term vision of the team is to apply this technology to biointelligent medication will ultimately be dependent upon the ability to eliminate the inorganic silicon substrate from the processors to leave devices which are purely bio-organic and can therefore be administered in vivo

The New Ethernet

choice in enterprise LANs. With the explosion of Internet Protocol (IP) traffic
and sophisticated applications driving the demand for greater bandwidth inside
and outside the enterprise, Intel is helping the industry take Ethernet to greater
speeds and performance in the LAN, as well as extend Ethernet into new market
segments including wireless, storage and metro area networking.
Advancements in Ethernet technology are at the center of today’s transitions to:
Gigabit speeds in the enterprise
Wireless networking
Networked storage
Ethernet in the metropolitan area network
This paper provides information on these trends, why they are happening and,
most important, how to benefit from these transitions as the demand for faster
and more efficient network infrastructure increases.

Intel's 65 nanometer process technology

2006-01-30T02:56:00.000-08:00

Intel has reached a significant milestone in developing next-generation chip manufacturing technology by building fully functional 70-megabit static random access memory (SRAM) chips with more than half a billion transistors. The new chips were manufactured using the world's most advanced 65-nanometer (nm) process technology. The achievement extends Intel's efforts to develop new manufacturing process technology every two years, in accordance with Moore's Law.

The transistors in the new 65-nm (a nanometer is one-billionth of a meter) technology have gates (the switch that turns a transistor on and off) measuring 35 nm, approximately 30 percent smaller than the gate lengths on the earlier 90-nm technology. About 100 of these gates could fit inside the diameter of a human red blood cell.

The new process technology increases the number of tiny transistors squeezed onto a single chip, providing the foundation on which to deliver future multicore processors. It will also enable Intel to design innovative features into future products, including virtualization and security capabilities. This new 65-nm process te chnology also includes several unique power-saving and performance-enhancing features.

Exercise for back pain

2006-01-14T03:07:00.000-08:00

Healing through back pain exercise
Active forms of back pain exercise (physical therapy) are typically necessary to rehabilitate the spine and help alleviate back pain. Importantly, a regular back pain exercise routine provides patients with the means to help avoid recurrences of low back pain, and helps reduce severity and duration of potential future episodes of low back pain.
The natural stimulus for the back to heal is active back pain exercises, done in a controlled, gradual, and progressive manner. Movement distributes nutrients into the disc space and soft tissues in the spine to keep the discs, muscles, ligaments and joints healthy. And the converse is true too—lack of exercise can worsen back pain by leading to stiffness, weakness, and de-conditioning.
Generally, a patient’s back pain exercise program should encompass a combination of stretching exercises (such as hamstring stretching), strengthening exercises (such as dynamic lumbar stabilization exercise, Mckenzie exercise, or other back exercise programs) and low impact aerobics (such as walking, bicycling, water therapy or swimming). Depending the patient’s specific diagnosis and level of pain, the back pain exercise and rehabilitation program will be very different, so it is important for patients to see a spine specialist who is trained to develop an individualized exercise program provide instruction on using the correct form and technique.
Stretching as part of a back pain exercise routine
Almost everyone can benefit from stretching the soft tissues—the muscles, ligaments and tendons—in the back and around the spine. The spinal column and its contiguous muscles, ligaments and tendons are all designed to move, and limitations in this motion can accentuate back pain. Patients with chronic back pain may find it takes weeks or months of stretching to mobilize the spine and soft tissues, but will find that meaningful and sustained relief of low back pain typically follows the increase in motion.
Hamstring stretching exercise
The hamstring muscles seem to play a key role in low back pain, as patients who have low back pain tend to have tight hamstrings, and patients with tight hamstrings tend to have low back pain. It is not known which comes first, but it is clear that hamstring tightness limits motion in the pelvis and can place it in a position that increases stress across the low back. Therefore, it follows that stretching the hamstring muscles typically helps decrease the intensity of a patient’s back pain and the frequency of recurrences.
A hamstring stretching exercise routine should include applying pressure to lengthen the hamstring muscle for 30-45 seconds at a time, one to two times each day. The pressure on the muscle should be applied evenly and bouncing should be avoided, since a bouncing motion will trigger a spasm response in the muscle being stretched. The hamstring muscle may be stretched in a number of different ways. Options for hamstring stretching exercises, listed from most difficult to least difficult, include:
*The most common technique is to simply bend forward at the waist, with legs relatively straight, and try to touch the toes and hold this position.

*If this approach is not well tolerated, less strain is applied to the back by sitting on a chair and placing the legs straight out in front on another chair, then reaching forward to try to touch the toes. One leg at a time may be stretched.

*One of the least stressful stretching techniques is to lie on the floor and pull the leg up and straighten by holding onto a towel that is wrapped behind the foot. One leg at a time may be stretched.

*Another less stressful option is to lie on the floor, with the buttocks against a wall, and place the foot up against the wall and then try to push the knee straight. One leg at a time may be stretched.

With time the hamstring muscle will gradually lengthen, reducing stress to the low back. Stretching should not be linked to another back pain exercise routine, since those exercises may not be done on a daily basis. In order to make stretching exercise a part of one’s daily regimen, it is best to stretch every morning when getting up and before going to bed. Think of stretching exercises as good back hygiene.

Lung cancer

2005-12-31T02:43:00.000-08:00

Lung cancer is the uncontrolled growth of abnormal cells in one or both of the lungs. While normal lung tissue cells reproduce and develop into healthy lung tissue, these abnormal cells reproduce rapidly and never grow into normal lung tissue. Lumps of cancer cells (tumors) then form and disrupt the lung, making it difficult to function properly.
More than 87% of lung cancers are smoking related. However, not all smokers develop lung cancer. Quitting smoking reduces an individual's risk significantly, although former smokers remain at greater risk for lung cancer than people who never smoked. Exposure to other carcinogens such as asbestos and radon gas also increases an individual's risk, especially when combined with cigarette or cigar smoking.
The Prevention of Lung Cancer
Encouraging behavior modification is a significant first step to ultimately reducing the high number of lung cancer deaths each year. Yet, that is only part of the solution. On the latest research front, scientists are studying methods to actually prevent the development of lung cancer through natural and synthetic materials. In addition, researchers believe that legislation designed to dissuade people from starting to smoke, coupled with efforts to help people quit, will have a positive impact on the number of new lung cancer cases in the future.
Studies have confirmed that 85 to 95 percent of lung cancers are smoking related. Therefore, the primary way for people to reduce their risk of developing the disease is to quit. To non-smokers, this may seem easy; however, as many smokers who have tried to quit will attest, this is extremely difficult. The addiction to nicotine has been likened to that of heroin, perhaps even more powerful. This may account for why so many smokers fail numerous attempts to quit, as well as the strong rationale to increase assistance for those people who desire to quit smoking permanently.
While the risk for former smokers remains elevated – as compared to a non-smoker – the risk continues to fall with the number of years of smoking cessation. After 10 years of abstinence, a person who has quit smoking reduces their risk anywhere from 30 to 50 percent.
What is Chemoprevention? For individuals who demonstrate the greatest risk, researchers are currently conducting several new trials to test the use of natural and synthetic substances to prevent development of the disease. This new research has been coined, chemoprevention. These methods, including the use of chemotherapy, vitamins, diet, and hormone therapy, are being tested to not only reduce the risk of cancer, but also to reduce the chance that the cancer will recur (or come back). Some of these are being tested as single agents, while others are being tested in combination.
Because of the long lasting effect that tobacco’s cancer causing carcinogens have on the bronchial epithelium (lining of the lungs), each trial participant’s lung cancer risk – which correlates to their smoking history – is assessed. However, since not all smokers develop lung cancer, and not all patients diagnosed with the disease smoked, the risk assessment is not sufficient. Therefore, additional research to identify reliable proteins or gene biomarkers will be helpful in determining a person’s actual risk.
Today, we can detect changes in the cells of the base lining of the lungs from normal to pre-cancerous (dysplasia). There are already many treatments under investigation that may be used to successfully treat these dysplastic cells. In addition, new studies are helping investigators determine at what point chemoprevention becomes an appropriate option for pre-treating lung cancer.

Desktop Line Following Robot

2005-12-02T02:25:00.000-08:00

Recently many kind of robot contests have being opened and some interesting reports of the challenge are found on the web. The Line Following is a kind of the robot contests to vie running speed on the line. I build a tiny line following robot which can run on the desk, moving the key board aside will do. It is for only a personal toy reduced its size less than one fifth compared to typical line following robots, not in formura.
About Line Follower
The line follower is one of the self operating robot that follows a line that drawn on the floor. The basic operations of the line following are as follows:
1. Capture line position with optical sensors mounted at front end of the robot. Most are using several number of photo-reflectors, and some leading contestants are using an image sensor for image processing. The line sensing procss requires high resolution and high robustness.
2. Steear robot to track the line with any steearing mechanism. This is just a servo operation, any phase compensation will be required to stabilize tracking motion by applying digital PID filter or any other servo argolithm.
3. Control speed according to the lane condition. Running speed is limited during passing a curve due to friction of the tire and the floor.

There are two line styles, white line on the black floor and black line on the white floor. Most contest are adopting the first one in line width of between 15 and 25 millimeters.

Stem cell heart cure to be tested

2005-11-15T01:07:00.000-08:00

The study, at Barts and the London NHS Trust, is funded by a charity set up by a man who underwent stem cell treatment for his heart condition in Germany.
The aim will be to determine whether adult stem cells taken from bone marrow can repair damaged heart muscle.
In total, 700 patients will take part in the study, which will test three different forms of stem cell therapy
The first part of the study will involve 300 patients whose hearts are failing because of heart disease or a previous heart attack.
A second arm will involve 200 patients whose hearts are failing specifically because of dilated cardiomyopathy - a heart muscle disorder.
And a final element will involve 200 patients who have just had a heart attack.
Some patients will have stem cells extracted from bone marrow in their hip and injected into their major coronary arteries or directly into their heart.
Others will receive injections of growth factor drugs to try to cause stem cells to spill out of their bone marrow and into their blood without the need for the operation.

Web Browser History

2005-10-04T04:20:00.000-07:00

Dozens of different web browsers have been developed by various people and teams over the years.

The first widely used web browser was NCSA Mosaic. The Mosaic programming team then developed the first commercial web browser called Netscape Navigator, later renamed Communicator, then renamed back to just Netscape. The Netscape browser led in user share until Microsoft Internet Explorer took the lead in 1999 due to its advantage in being bundled with Windows operating systems. An open source version of Netscape was then developed called Mozilla, which was the internal name for the old Netscape browser, and released in 2002. Mozilla has since gained in market share, particularly on non-Windows platforms, largely due to its open source foundation, and in 2004 was released in the quickly popular FireFox version.

A chronological listing of some influential early web browsers is provided below, each of which advanced the state of the art:

* WorldWideWeb. Tim Berners-Lee wrote the first web browser on a NeXT computer, called WorldWideWeb, finishing the first version on Christmas day, 1990. He released the program to a number of people at CERN in March, 1991, introducing the web to the high energy physics community, and beginning its spread.

* libwww. Berners-Lee and a student at CERN named Jean-Francois Groff ported the WorldWideWeb application from the NeXT environment to the more common C language in 1991 and 1992, calling the new browser libwww. Groff later started the first web design company, InfoDesign.ch.

* Line-mode. Nicola Pellow, a math student interning at CERN, wrote a line-mode web browser that would work on any device, even a teletype. In 1991, Nicola and the team ported the browser to a range of computers, from Unix to Microsoft DOS, so that anyone could access the web, at that point consisting primarily of the CERN phone book.

* Erwise. After a visit from Robert Cailliau, a group of students at Helsinki University of Technology joined together to write a web browser as a master's project. Since the acronym for their department was called "OTH", they called the browser "erwise", as a joke on the word "otherwise". The final version was released in April, 1992, and included several advanced features, but wasn't developed further after the students graduated and went on to other jobs.

* ViolaWWW. Pei Wei, a student at the University of California at Berkeley, released the second browser for Unix, called ViolaWWW, in May, 1992. This browser was built on the powerful interpretive language called Viola that Wei had developed for Unix computers. ViolaWWW had a range of advanced features, including the ability to display graphics and download applets.

* Midas. During the summer of 1992, Tony Johnson at SLAC developed a third browser for Unix systems, called Midas, to help distribute information to colleagues about his physics research.

* Samba. Robert Cailliau started development of the first web browser for the Macintosh, called Samba. Development was picked up by Nicola Pellow, and the browser was functional by the end of 1992.

*Mosaic. Marc Andreessen and Eric Bina from the NCSA released the first version of Mosaic for X-Windows on Unix computers in February, 1993. A version for the Macintosh was developed by Aleks Totic and released a few months later, making Mosaic the first browser with cross-platform support. Mosaic introduced support for sound, video clips, forms support, bookmarks, and history files, and quickly became the most popular non-commercial web browser. In August, 1994, NCSA assigned commercial rights to Mosaic to Spyglass, Inc., which subsequently licensed the technology to several other companies, including Microsoft for use in Internet Explorer. The NCSA stopped developing Mosaic in January 1997.

* Arena. In 1993, Dave Raggett at Hewlett-Packard in Bristol, England, developed a browser called Arena, with powerful features for positioning tables and graphics.

* Lynx. The University of Kansas had written a hypertext browser independently of the web, called Lynx, used to distribute campus information. A student named Lou Montulli added an Internet interface to the program, and released the web browser Lynx 2.0 in March, 1993. Lynx quickly became the preferred web browser for character mode terminals without graphics, and remains in use today. Resources include the Browser.org Lynx page, the ISC Lynx page, and the Lynx User Guide.

* Cello. Tom Bruce, cofounder of the Legal Information Institute, realized that most lawyers used Microsoft PC's, and so he developed a web browser for that platform called Cello, finished in the summer of 1993.

* Opera. In 1994, the Opera browser was developed by a team of researchers at a telecommunication company called Telenor in Oslo, Norway. The following year, two members of the team -- Jon Stephenson von Tetzchner and Geir Ivarsøy -- left Telenor to establish Opera Software to develop the browser commercially. Opera 2.1 was first made available on the Internet in the summer of 1996.

* Internet in a box. In January, 1994, O'Reilly and Associates announced a product called Internet In A Box which collected all of the software needed to access the web together, so that you only had to install one application, instead of downloading and installing several programs. While not a unique browser in its own right, this product was a breakthrough because it distributed other browsers and made the web a lot more accessible to the home user.

* Navipress. In February, 1994, Navisoft released a browser for the PC and Macintosh called Navipress. This was the first browser since Berners-Lee's WorldWideWeb browser that incorporated an editor, so that you could browse and edit content at the same time. Navipress later became AOLPress, and is still available but has not been maintained since 1997.

* Mozilla. In October, 1994, Netscape released the the first beta version of their browser, Mozilla 0.96b, over the Internet. On December 15, the final version was released, Mozilla 1.0, making it the first commercial web browser. An open source version of the Netscape browser was released in 2002 was also named Mozilla in tribute to this early version, and then released as the quickly popular FireFox in November, 2004.

* Internet Explorer. On August 23rd, 1995, Microsoft released their Windows 95 operating system, including a Web browser called Internet Explorer. By the fall of 1996, Explorer had a third of market share, and passed Netscape to became the leading web browser in 1999.

Packet Telephony

2005-09-01T23:00:00.000-07:00

Packet Telephony consists of telephony and data tightly coupled on packet based switched multimedia networks. The packet telephony simply refers to the use of personal computers and a packet data network to produce a voice conversation. The goal of packet switched fabric in both LAN and WAN, the vision in to drive voice and data over a single multimedia (packet based N/W) allowing waves to engage in a media rich communication in a natural and straight-forwarded manner. The packet & based fabric is capable of supporting future applications such as video streaming and video conferencing. The transaction to a new paradigm will take years to complete. However technology matures and new application proliferate packet technology will appear in broader market. There is a major distinction between Intranet telephony and VoIP. While VoIP, which usually takes place in managed networks of large corporate is allowed in India. Internet telephony which occurs in public network is not allowed in India.

Multimedia Broadcasting via Satellite

2005-09-01T22:57:00.000-07:00

Simply put, a satellite is a microwave receiver, repeater, and regenerator in orbit above the earth. Satellite transmission involves sending signals to an orbiting satellite that receives them, amplifies them, and returns those signals back to earth. The advancement and standardization of satellite transmission technology has created a new opportunity to deliver Internet protocol (IP)-based services to sites around the world. This new opportunity offers exciting possibilities for efficient transmission of streaming and/or large file data from a centralized location to remote sites anywhere in the world.
Multimedia broadcasting by satellite enables the expansion of communications in both the Internet and enterprise businesses. Typically, these applications are ones that already involve or could benefit from the use of video and audio presentations. Satellite delivery is the right solution for the applications described in this document because satellites provide a compelling economic solution, and the wireless connectivity of satellites enables access to areas of countries or regions that have limited access to terrestrial alternatives.

Wikipedia

2005-08-31T22:21:00.000-07:00

Chances are that you have heard of Wikis by now -- they seem to be popping up everywhere. For example, The most famous wiki is called Wikipedia, a massive online encyclopedia. Wikipedia has become so large (more than a million articles) that you run across it all the time in Google. It is so popular that it is now one of the Top 100 web sites in the world!

Despite their popularity, Wikis seem very strange to many people. Where does all the information come from? Is it reliable? What stops people from vandalizing a wiki until it dies? These questions and many others will be answered as we dive into the world of wikis...
Wikis are growing because, at their core, they are about as simple as can be. That simplicity means that people find them easy to use, just like e-mail and blogs. Like e-mail and blogs, wikis also perform a very useful service in a simple way. A wiki allows a group of people to enter and communally edit bits of text. These bits of text can be viewed and edited by anyone who visits the wiki.

That's it. What it means is that, when you come to a wiki, you are able to read what the wiki's community has written. By clicking an "edit" button on an article, you are able to edit the article's text. You can add or change anything you like in the article you are reading.

Padmarajan: A Loss in January

2005-08-31T22:01:00.000-07:00

Padmarajan died in a cold January, untimely. He was in a hotel at calicut, in the middle of a celebration of his latest film Njaan Gandharvan (I, the celestial enchanter), in 1991. It was as if audience of the show was subjected to a dismayed silence, and the show was stalled. I for one who had just begun waking upto adolescence and the charm of his creative genius, felt the void, instantly.

Padmarajan started his career as a writer. Unfortunately I have not read any of his books. I know him from his films. If the literary quality of his films is anything to go by, they must be a world to discover. In fact like most of the films, his first film was based on his own novel Peruvazhiyambalam (The grand roadway Inn, 1979). The movie tore down the mythical fence between popular and art house movies. He pioneered the middle of the road solution for commercially succesfull good films and began a short lived golden period of malayalam films alongside Bharathan, Aravindan and M.T. Vasudevan Nair.

The plot of Peruvazhiyambalam was set in a non-descript village somewhere in kerala. It revolved around Raman, an adolescent who inadvertantly killed Prabhakaran Pillai in a scuffle. Pillai, a local bully persecuted him and coveted his sister. After the incident Raman lived in hiding with the help of a truck driver and a prostitute. The movie ended with Raman's realization of his persona as a ravager of Pillai's hapless family. We find the extra-ordinary circumstances in the lives of ordinary people and the choices they made to deal with them.

However the movie was a riot in a deeper sense when Padmarajan ever so subtly slipped in the psychoanalytical threads to metatag the life of Raman in lieu of his insecurities as a teenager, his perceptions of sexuality and growth in a seemingly hostile world. Another aspect of the movie was the use of violence as a leitmotif, which later became an identity of his oeu·vre. He was perhaps the only indian director to deal with psychosis and clinical psychology with some competence. Its interesting to watch him map the animalistic psychological behaviour of his characters to the spatial fields of social consciousness, with an amazing flair for story telling.

Padmarajan is known for his native and localized plots and characters. It is a little unfair on the non-native viewer to pick up on the nuances, but then so was Faulkner's art and so was Ozu's art. I have marvelled at this comparison for sometime. Faulkner's southerner retard Benjy imparted a shock to the readers and similarly viewers were shaken by Padmarajan's blend of anarchist and sexually challenged protagonists.

He made Oridathu Oru Phayalvaan (There lived a wrestler, 1982), a folk parable about the success and failure in the life of a wrestler whose successes in the wrestling arena were starkly contrasted with his sexual impotency. This film portrayed the marginal characters (like the frog catchers) with such brilliance that the movie had an organic existence delineated in a multi dimensional narrative. It provoked an urgent and instant response from the audience. Kallan Pavithran (Pavithran, the thief, 1981) and Arappatta kettiya gramathil (The village with a waist band, 1986) - the story of a bunch of prostitutes and pimps in a village) had the stamp of his magic with precision, warmth and an empathy devoid of prejudice. It was life unclassified.

Like Ozu, Padmarajan was a story teller and relied on the total impact rather than partial brilliance. Philosophically he seemed to share Ozu's social conservatism and perennially interested in the concepts of epic and lyrical times. He even made a movie similar to Ozu's Tokyo Story, Thinkalazcha, Nalla Divasam (Monday, the Good Day).

He went on to make major movies such as Namukku Parkan Munthiri Thoppukal (1986) (Vineyards for us to live), Thoovanathumpikal (1987), Moonnaam Pakkam (The third day) (1988), Aparan (1988), Innale (1989) and finally Njan Gandharvan - 1991 (The Celestial Lover). Each movie followed a different genre in themes, techniques and plots. If the movie, Vineyards to live was an inspired take off on Solomon's song and a beautifull thought on the biblical promise of vineyard for each other by lovers, The Celestial lover was about the phantasmagoric life of a nubile where she found her heavenly lover out of the blue sky, only to be punished by higher powers.

Ironically Padmarajan vanished abruptly, amid life's celebration and at the peak of his almost ethereal creative powers. His films spanned a little over a decade. In the first half he displayed an exceptional ability to bring raw power and subliminal nature of human relationships and the next half lingered more on his liking for variety and experimentation. He endeared most of the viewers like myself with his earlier movies. I was hoping to watch him cover unchartered waters, with the unprecedented support from almost all sections of movie goers. Everything looked perfectly set. But then there was this intervention of death.

Quantum cryptography

2005-08-23T12:38:00.000-07:00

Quantum cryptography is an effort to allow two users of a common communication channel to create a body of shared and secret information. This information, which generally takes the form of a random string of bits, can then be used as a conventional secret key for secure communication. It is useful to assume that the communicating parties initially share a small amount of secret information, which is used up and then renewed in the exchange process, but even without this assumption exchanges are possible.
The advantage of quantum cryptography over traditional key exchange methods is that the exchange of information can be shown to be secure in a very strong sense, without making assumptions about the intractability of certain mathematical problems. Even when assuming hypothetical eavesdroppers with unlimited computing power, the laws of physics guarantee (probabilistically) that the secret key exchange will be secure, given a few other assumptions.

Artificial eye

2005-08-23T12:32:00.000-07:00

The retina is a thin layer of neural tissue that lines the back wall inside the eye. Some of these cells act to receive light, while others interpret the information and send messages to the brain through the optic nerve. This is part of the process that enables us to see. In damaged or dysfunctional retina, the photoreceptors stop working, causing blindness. By some estimates, there are more than 10 million people worldwide affected by retinal diseases that lead to loss of vision.
The absence of effective therapeutic remedies for retinitis pigmentosa (RP) and age-related macular degeneration (AMD) has motivated the development of experimental strategies to restore some degree of visual function to affected patients. Because the remaining retinal layers are anatomically spared, several approaches have been designed to artificially activate this residual retina and thereby the visual system.
At present, two general strategies have been pursued. The "Epiretinal" approach involves a semiconductor-based device placed above the retina, close to or in contact with the nerve fiber layer retinal ganglion cells. The information in this approach must be captured by a camera system before transmitting data and energy to the implant.
The "Sub retinal" approach involves the electrical stimulation of the inner retina from the sub retinal space by implantation of a semiconductor-based micro photodiode array (MPA) into this location. The concept of the sub retinal approach is that electrical charge generated by the MPA in response to a light stimulus may be used to artificially alter the membrane potential of neurons in the remaining retinal layers in a manner to produce formed images.
Some researchers have developed an implant system where a video camera captures images, a chip processes the images, and an electrode array transmits the images to the brain. It's called Cortical Implants.

3D PC Glasses

2005-08-23T11:50:00.000-07:00

Only a few years ago, seeing in 3-D meant peering through a pair of red-and-blue glasses, or trying not to go cross-eyed in front of a page of fuzzy dots. It was great at the time, but 3-D technology has moved on. Scientists know more about how our vision works than ever before, and our computers are more powerful than ever before -- most of us have sophisticated components in our computer that are dedicated to producing realistic graphics. Put those two things together, and you'll see how 3-D graphics have really begun to take off.

Most computer users are familiar with 3-D games. Back in the '90s, computer enthusiasts were stunned by the game Castle Wolfenstein 3D, which took place in a maze-like castle. It may have been constructed from blocky tiles, but the castle existed in three dimensions -- you could move forward and backward, or hold down the appropriate key and see your viewpoint spin through 360 degrees. Back then, it was revolutionary and quite amazing. Nowadays, gamers enjoy ever more complicated graphics -- smooth, three-dimensional environments complete with realistic lighting and complex simulations of real-life physics grace our screens. But that's the problem -- the screen. The game itself may be in three dimensions, and the player may be able to look wherever he wants with complete freedom, but at the end of the day the picture is displayed on a computer monitor...and that's a flat surface.

That's where PC 3-D glasses come in. They're designed to convince your brain that your monitor is showing a real, three-dimensional object. In order to understand quite how this works, we need to know what sort of work our brain does with the information our eyes give it. Once we know about that, we'll be able to understand just how 3-D glasses do their job.

Computer memory based on the protein bacterio-rhodopsin

With existing methods fast approaching their limits, it is no wonder that a number of new storage technologies are developing. Currently, researches are looking at protien-based memory to compete with the speed of electronic memory, the reliability of magnetic hard-disks, and the capacities of optical/magnetic storage. We contend that three-dimensional optical memory devices made from bacteriorhodopsin utilizing the two photon read and write-method is such a technology with which the future of memory lies.

In a prototype memory system, bacteriorhodopsin stores data in a 3-D matrix. The matrix can be build by placing the protein into a cuvette (a transparent vessel) filled with a polyacrylamide gel. The protein, which is in the bR state, gets fixed in by the polymerization of the gel. A battery of Krypton lasers and a charge-injection device (CID) array surround the cuvette and are used to write and read data.

While a molecule changes states within microseconds, the combined steps to read or write operation take about 10 milliseconds. However like the holographic storage, this device obtains data pages in parallel, so a 10 Mbps is possible. This speed is similar to that of slow semiconductor memory.
