...From the Editors A recent cover story published by one of the most inºuential magazines in the world, the Economist (March 12–18, 2005), revealed for its readers the “Real Digital Divide.” The lead essay (written primarily by technology editor Tom Standage) pointed to an unexpected shift in the world’s attention from computers as the main technology deªning the digital divide to the cell phone. The tone of the article, characteristically, was that of a scold pointing to old shibboleths that have been proven false. First, readers were warned that one proposal to resolve the digital divide—creating a global infrastructure fund focused on computers and the Internet—was especially misguided. According to the authors, markets work better. Second, readers were admonished to shift their attention from the Internet to the increasingly ubiquitous cell phone. The Economist is right in insisting that ICT for development policies need to be constantly reevaluated in light of the current best research ªndings. For example, it takes a justiªably critical look at an overreliance on telecenters as the once-favored answer to digital divides. At the same time, the Economist commits similar errors of oversimpliªcation of which it accuses others. It creates a straw man (in the form of an Internet-for-development evangelist), which it then easily knocks down. It accomplishes this by substituting one kind of new technology, mobile phones, for another kind of new technology. It may well be that the...

...GA, USA a r t i c l e i n f o a b s t r a c t Nanotechnology is an emerging field of science devoted to provide new opportunities in a vast range of areas. In this paper, different techniques are proposed to enable the long range interconnection of nano-machines, deployed over distances from a few centimeters up to several meters. Long range nano-communications will enable the development of applications that could not be implemented using other techniques. The usage of both short-range nano techniques and long range micro techniques are not practical or are unfeasible for a huge application scope. Biologically inspired research provides promising features to long range communication, such as very low power consumption and biocompatibility. In this paper, several bio-inspired techniques are discussed following a twofold taxonomy divided according to whether a fixed physical link is required for signal propagation or not, i.e., either wired or wireless communication. In the first group, pheromones, spores, pollen and light transduction are discussed. In the second group, neuron-based communication techniques and capillaries flow circuit are explored. All proposed techniques offer a good framework for long-range molecular communication, and their components and test-beds can benefit from different research expertise, e.g., entomology for pheromones, mycology for spores, neuroscience for axons, and biochemistry for capillaries.

...The cytotoxicity of natural killer cells is a topic that is still being investigated today, specifically the question at hand is “How does a cytotoxic T cell (or NK cell) avoid being killed by the perforin and granzymes that it secretes to kill a target cell?” In the field, what is known about the topic includes the function of these natural killer cells, the mechanism of action of the perforin released by these cells, and health issues associated with nonfunctional perforin. Natural killer cells are a type of white blood cells that play significant roles in viral infections and host-rejection of tumors and are cytotoxic because they contain perforin and granzymes. When cytotoxic T lymphocytes and natural killer cells are activated, they produce...

...com/content/8/1/32 REVIEW Open Access Understanding India, globalisation and health care systems: a mapping of research in the social sciences Ramila Bisht1*, Emma Pitchforth2 and Susan F Murray3 Abstract National and transnational health care systems are rapidly evolving with current processes of globalisation. What is the contribution of the social sciences to an understanding of this field? A structured scoping exercise was conducted to identify relevant literature using the lens of India – a ‘rising power’ with a rapidly expanding healthcare economy. A five step search and analysis method was employed in order to capture as wide a range of material as possible. Documents published in English that met criteria for a social science contribution were included for review. Via electronic bibliographic databases, websites and hand searches conducted in India, 113 relevant articles, books and reports were identified. These were classified according to topic area, publication date, disciplinary perspective, genre, and theoretical and methodological approaches. Topic areas were identified initially through an inductive approach, then rationalised into seven broad themes. Transnational consumption of health services; the transnational healthcare workforce; the production, consumption and trade in specific health-related commodities, and transnational diffusion of ideas and knowledge have all received attention from social scientists in work related to India. Other themes...

... | Introduction Verizon Wireless is one of the major cell phone companies in the United States. According to its website, it has 73,000 employees and over 1900 retail locations. Its annual revenue in 2012 was $75.9 billion.Verizon Wireless was founded in 2000 by Verizon Communications and Vodafone. This company is very successful in the retail channel. Having worked in this channel with the company for three years and being a customer of the company for eight years has given insight into how important productivity is for continued success. (http://aboutus.verizonwireless.com/company/story/) In 2000, Vodafone AirTouch and Bell Atlantic Corp. received regulatory approval to combine their U.S. wireless assets, Bell Atlantic Mobile and AirTouch Communications. This $90-billion joint venture began operations as Verizon Wireless on April 4, 2000. Verizon quickly grew as it acquired other cellular companies. In 2000 it acquired network from Bell Atlantic. Rural Cellular Corporation was acquired in 2008. Alltel, a popular southern cell phone company was acquired the next year. In that same year Verizon Wireless developed a partnership with Google to promote the new cell phone operating system Android with a line of cell phones specifically for Verizon Wireless called DROID.

...TERM PAPER NAND and NOR Flash Memory -by Shashank Chaudhay 2010EE10480 Abstract- This term paper is an introduction to the flash memory devices both NAND and NOR. This includes - history of flash memory - how it works - NOR flash memory type - NAND flash memory type - differences between them - limitations of flash memory 1. Introduction Two main technologies dominate the non-volatile flash memory market today: NOR and NAND. Flash memory (both NOR and NAND types) was invented by Dr. Fujio Masuoka while working for Toshiba circa 1980. According to Toshiba, the name "flash" was suggested by Dr. Masuoka's colleague, Mr. Shōji Ariizumi, because the erasure process of the memory contents reminded him of the flash of a camera. NOR flash was first introduced in market by Intel in 1988, revolutionizing a market that was then dominated by EPROM and EEPROM devices. NAND flash architecture was introduced in the market by Toshiba in 1989.Most hardware engineers are not familiar with the differences between these two technologies. In fact, they usually refer to NOR architecture as “flash”, unaware of NAND flash technology and its many benefits over NOR. This is mainly due to the fact that most flash devices are used to store and run code (usually small), for which NOR flash is the default choice. Unlike Dynamic Random Access Memory (DRAM), Flash memory is non-volatile. Non-volatile memory retains data even without being powered-on. For example, when a computer...

A good example is found in the development of the mobile phones. Technological development, embodied in innovative functions developed from the first (1G) to third generation (3G) systems, has played significantly important roles in the growth and upheavals of the Japanese mobile phone market. In addition, development in contents, value-added services which are supplied by related firms formed in the vertical structure, charging systems, handset development; all these have made this small gadget an increasingly important part of daily life. This paper heuristically analyzes the effect of technological innovations and competition policies on the diffusion of 3G mobile phones in Japan. In particular, this paper attempts to identify what are factors to promote the Japanese 3G mobile phone by using panel data analysis. In constructing an estimation model, the number of subscribers to 3G mobile phone services is taken...
