A number of important misconceptions or fallacies stand in the way of a better understanding of the nation’s flood problem. The fallacies are not universal, with many flood experts, decision makers, and sectors of the public escaping their seductive logic. But enough people do fall prey to these fallacies of floods so as to create obstacles to improved utilization of the lessons of experience. ...

Let {p θ , θ ∈ Θ} be a family of probability densities with respect to µ where Θ is an open subinterval (finite, infinite or semi-infinite) of the real line. The Fisher Information for this family is defined by: I(θ) := E θ ∂ ∂θ log p θ (X) 2 Note that the densities p θ can be on arbitrary spaces; the only condition for defining I(θ) is that θ is real. The function ∂ ∂θ log p θ (X) is called th...

In recent years, a number of games have been solved using computers. These include Qubic [Patashnik 80], Connect-4 [Allen 89], [Allis 88] and Go-Moku [Allis 93]. All these games were solved using knowledge-based methods. These methods are successful because all these games have a low “decision complexity” [Allis 90], i.e., the right move is often easy to find. Not all games profit to the same e...

Presidential Fellow Biology I am interested in vegetation patterns and how these patterns change as we shift from a local to a global perspective. At the landscape scale, we know that vegetation patterns are controlled by a combination of environment, historical events, and population dynamics, but the relative importance of these three elements is hotly debated. Using emerging airborne remote ...

Quantum computing on encrypted data (or QCED for short) is a family of techniques and protocols that allow the evaluation of some quantum function on a quantum input, while hiding that input from the party that performs the evaluation. This is useful in a setting involving two or more parties, some of which cannot be trusted: for example, a client holding some sensitive input may want to outsou...

background chronological aging is associated with a decrease in physical activity levels and consequently a decline in physical fitness, which may contribute to adverse conditions such as cardiovascular disease, hypertension, obesity and physical impairment. objectives this study sought to examine the effects of an 8-week physical activity intervention program on nutritional status and health-r...

renal transplantation is considered one of the best long-term therapies for chronic renal failure, but unfortunately the incidence of malignancy significantly increases in renal transplant recipients. we analyzed nine cases of malignancy in 200 renal transplant recipients occurring in a 12-year follow-up in imam hospital of tehran university, tehran, iran. according to this study, the organ mos...
