  • In the latest years much research effort was devoted to envision a new paradigm for wireless transmission. Results from recent works (Wireless Word Research Forum, 2005) indicate that a possible solution would lie in utilizing in a more efficient manner the diverse Radio Access Technologies1 (RATs) that are available nowadays, with the purpose of enabling interoperability among them and convergence into one global telecom infrastructure (beyond 3G).

  • Even this figure doesn’t tell the whole story, however. Looking forward, many businesses realize their future competitiveness will depend on new business strategies and deeper insights that might require data that isn’t even being captured today. Projecting five years out, businesses shouldn’t be surprised if they want to store and analyze a rapidly growing data pool that is 100 times or more greater than the size of today’s data pool. And beyond size, the depth of analysis and complexity of business questions raised against the data can only be expected to grow.

  • Introduction: Local anaesthetics reversibly block neural transmission in local tissues. The drugs are bound with specific receptors located inside the sodium channels of cell membranes, and thus block the permeability of sodium ions; this is the mechanism of anaesthetic action of these drugs. As the history of local anaesthetics, Von Anrep discovered the local anaesthetic action of an alkaloid cocaine being contained in the leaves of Erythroxylon coca. Then, Karl Koller used cocaine as a local anaesthetic in ophthalmological surgery.

  • Social media is not the only emerging channel P&G is using to connect directly with consumers. In November 2011 the company announced a partnership with a start-up called Mobeam to distribute digital coupons via mobile phones. The companies plan to begin testing the solution—which requires enhancements to existing handsets—in 2012. Diageo is another CG manufacturer that has also turned to social media—Facebook specifi cally—to enhance its consumer marketing efforts and drive retail beverage sales.

  • Independent Component Analysis (ICA) is a signal-processing method to extract independent sources given only observed data that are mixtures of the unknown sources. Recently, Blind Source Separation (BSS) by ICA has received considerable attention because of its potential signal-processing applications such as speech enhancement systems, image processing, telecommunications, medical signal processing and several data mining issues.

  • In this paper we develop a contingent valuation model for zero-coupon bonds with de- fault. In order to emphasize the role of maturity time and place of the lender’s claim in the hierarchy of debt of a Þrm, we consider a Þrm that issues two bonds with different ma- turities and different seniorage. The model allows us to analyze the implications of both debt renegotiation and capital structure of a Þrm on the prices of bonds.

  • In this section we look at data concerning 10-year government bond yields. Although our main interest is the default risk, this presents only one channel through which fiscal policies can affect long-term yields. There are other channels operating through monetary-fiscal interaction, which should be reflected in the evolution of yields. Therefore we start our descriptive analysis in this section by looking at yields, forward rates and inflation expectations at a weekly frequency. Then we move to an analysis of interest rate swap spreads, at a weekly and daily frequency.

  • World cocoa price has fallen by some 48% over the past three years, with direct impacts on the incomes, health and nutrition of cocoa producers and their family in the two major producing countries: Côte d’Ivoire and Ghana, with some 41% and 22% of world output, respectively. The impact of the price drop has been far different in the two countries because of the greater age of plantations, market liberalisation, presence of free agents in the marketing channel, and much greater socio-political instability in one country: Côte d’Ivoire.

  • In 1987 my father and I purchased a seat on the New York Futures Exchange for $100 and established a trading account with $25,000. The goal, he explained, was to make $2,500 a week. Although this seemed like an extraordinary annualized return on investment, I had heard of legendary traders who had taken meager sums and transformed them into vast fortunes, and so I embarked on a journey that eventually culminated in the publication of this book.

  • Brain serine racemase contains pyridoxal phosphate as a prosthetic group and is known to become activated by divalent cations such as Ca 2+ and Mg2+ , as well as by ATP and ADP. In vivo, brain serine racemase is also activated by a multi-PSD-95⁄discs large⁄ZO-1 (PDZ) domain glutamate receptor interacting protein (GRIP) that is usually coupled to the GluR2⁄3 subunits of the a-amino-3-hydroxy-5-methylisoxazole-4-propionic acid Ca 2+ channel.

  • Multicast services on public television include the World Channel, Create, V-Me, and MHz Worldview. Many public television stations have created their own multicast channels, including C-SPAN-like services that offer coverage of state and local government, educational channels, and cultural channels. A significant number of public radio stations have converted their analog transmission plants to digital technology. Public radio has not only been a leader in adopting multicast technology, NPR was a leader in developing the technology that permits multicast operation.
