  • We also present a variant of the algorithm that performs modular multiplication by interleaving the shift-and-add and the modular reduction steps. The modular multiplication algorithm can be used to obtain efficient VLSI implementations of exponentiation cryptosystems.

  • Cognitive radio is a hot research area for future wireless communications in the recent years. In order to increase the spectrum utilization, cognitive radio makes it possible for unlicensed users to access the spectrum unoccupied by licensed users. Cognitive radio let the equipments more intelligent to communicate with each other in a spectrum-aware manner and provide a new approach for the co-existence of multiple wireless systems.

  • This work develops and defends a structural view of the nature of mathematics, which is used to explain a number of striking features of mathematics that have puzzled philosophers for centuries. It rejects the most widely held philosophical view of mathematics (Platonism), according to which mathematics is a science dealing with mathematical objects such as sets and numbers—objects which are believed not to exist in the physical world.

  • this report showcases smart marketing strategies from clean energy programs and solar marketers from across the country that address how to overcome the barriers faced by solar technology markets and serves as a guide for states in pursuing their own market planning process. While there has been a major increase in solar photovoltaic (pV) installations in recent years, the total amount of solar power installed nonetheless represents less than 0.1% of u.s. energy production.

  • When small, independent providers want to negotiate with multiple health plans, large insurers exert enormous pressure to stop them. The statewide trade group for doctors in New York sued UnitedHealth Group Inc., the nation’s second-largest health insurer by enrollment, for allegedly using illegal coercion in just such a scheme to limit competition.26 In a separate matter UnitedHealth agreed to pay $400 million to settle multiple suits alleging price fixing and other anti-competitive behavior.

  • Exposure to carbon monoxide reduces maximum exercise ability in healthy young individuals and reduces the time to angina and, in some cases, the time to ST-segment depression in people with cardiovascular disease, albeit at a con- centration that is lower than that needed to reduce exercise ability in healthy in- dividuals.

  • Historically, the Ontario Medical Association (OMA) has taken a strong stand advocating reductions in air pollution in Ontario as an essential means to improve public health. Beginning in 1967, the Ontario Medical Association Council endorsed a program of air pollution control in Ontario which included the establishment of monitoring stations and regulation of emissions from industry and vehicular traffic (15). Shortly thereafter, the government enacted the Air Pollution Control Act encompassing a number of the recommendations from the OMA.

  • Since the early 1980s, much time and effort has been expended in trying to understand the relative contributions of different social factors in mortality decline (especially declines in infant and child mortality) and in reductions in fertility. In these debates, the schooling level (number of years attended) of a young mother has often been portrayed as the single most powerful correlate of reductions in the infant and child mortality of her children, and (to a lesser but still very considerable degree) to reduction in her completed family size.

  • Server Consolidation: Oracle RAC databases or Oracle RAC One Node databases with underutilized CPU resources or variable CPU utilization can often benefit from consolidation with other workloads using server virtualization. A typical use case for this scenario would be the consolidation of several Oracle databases (Oracle RAC, Oracle RAC One Node or Oracle single instance databases) into a single Oracle RAC database or multiple Oracle RAC databases where the hosting Oracle VM guests have pre-defined resource limits configured for each VM guest. ...

  • Economic crises are historically times of industrial renewal. Less efficient firms fail while more dynamic ones emerge and expand. Creative destruction is an essential engine of long term efficiency in market economies, and it intensifies in downturns. Available data for many OECD countries point to a sharp increase in bankruptcies and business failures in recent months. New business models and new technologies, particularly those allowing a reduction in cost, often arise in downturns, as was the case with low-cost airlines which grew out of the recession of the early 1990s.

  • This paper analyzes junk bond defaults during 1980 to 1991 to determine which factors affect the length of time spent in default. Bondholder holdouts are not a significant problem, as firms with proportionately more bonds have shorter default spells. In contrast, bank debt is associated with slower restructurings. Bargaining problems arising from contingent liabilities, lawsuits, and size delay the process, although multiple bond classes do not. Neither information problems nor firm value appear to matter. HLTs do not resolve their defaults at a significantly faster pace.

  • By inadvertently increasing the concentration of energy-trapping gases in the lower atmosphere, human actions have begun to amplify Earth’s natural green- house effect. The primary challenge facing the world community is to achieve sufficient reduction in greenhouse gas emissions so as to avoid dangerous inter- ference in the climate system. National governments, via the UN Framework Convention on Climate Change (UNFCC), are committed in principle to seeking this outcome.

  • In the underlying finite field arithmetic of an elliptic curve cryptosystem, field multiplication is the next computational costly operation other than field inversion. We present two novel algorithms for efficient implementation of field multiplication and modular reduction used frequently in an elliptic curve cryptosystem defined over GF (2n ).

  • At a prime of ordinary reduction, the Iwasawa “main conjecture” for elliptic curves relates a Selmer group to a p-adic L-function. In the supersingular case, the statement of the main conjecture is more complicated as neither the Selmer group nor the p-adic L-function is well-behaved. Recently Kobayashi discovered an equivalent formulation of the main conjecture at supersingular primes that is similar in structure to the ordinary case. Namely, Kobayashi’s conjecture relates modified Selmer groups, which he defined, with modified padic L-functions defined by the first author.

  • Differential Diagnosis CENTRAL CYANOSIS (Table 35-1) Decreased SaO2 results from a marked reduction in the Pa O2. This reduction may be brought about by a decline in the FIO2 without sufficient compensatory alveolar hyperventilation to maintain alveolar PO2. Cyanosis usually becomes manifest in an ascent to an altitude of 4000 m (13,000 ft).

  • One concern about the voluntary offset market as it continues to grow is the possibility that suppliers may sell the same reductions to multiple buyers, because there is no central authority to track their transactions. Related to this, questions can arise in some instances about who “owns” emission reductions and who in fact has the right to sell them. In some cases, multiple parties may conceivably lay claim to the same reduction.

  • The reduction in fixed ICT spending is gradually exploited by the new and exist- ing firms, and the speed of adoption of the new possibility remains an unknown variable for us. It will depend on a number of macroeconomic and microeconomic factors and on policymaking as well. Moreover, it will be characterized by impor- tant strategic complementarities: adoption for a single firm is crucial if many firms are expected to adopt it, but it is not if they are not, which means that multiple equilibria could emerge (with slow or rapid adoption and with limited or deep adoption).
