OBJECTIVE We use a case-crossover analysis to explore the association between incident cardiovascular events and residential relocation to a new home address. METHODS We conducted an ambidirectional case-crossover analysis to explore the association between incident cardiovascular events and residential relocation to a new address using data from the Cardiovascular Health Study (CHS), a commu...

The trapdoor channel is a binary input/output/state channel with state changing deterministically as the modulo2 sum of the current input, output and state. At each state, it behaves as one of two Z channels, each with crossover probability 1/2. Permuter et al. formulated the problem of finding the capacity of the trapdoor channel with feedback as a stochastic control problem. By solving the co...

We report fluorescence blinking statistics measured from single CdSe nanorods (NRs) of seven different sizes with aspect ratios ranging from 3 to 11. This study also included core/shell CdSe/ZnSe NRs and core NRs with two different surface ligands producing different degrees of surface passivation. We compare the findings for NRs to our measurements of blinking statistics from spherical CdSe co...

We simulated a growth model in (1+1) dimensions in which particles are aggregated according to the rules of ballistic deposition with probability p or according to the rules of random deposition with surface relaxation (Family model) with probability 1-p. For any p>0, this system is in the Kardar-Parisi-Zhang (KPZ) universality class, but it presents a slow crossover from the Edwards-Wilkinson ...

Path cost optimization is essential for maneuvering vehicles in a cost effective way. The term cost can be interpreted as fuel consumption, path visibility, probability of being detected, probability of being attacked or a combination of the above. Exact algorithms such as linear programming and dynamic programming can always provide globally optimum solution to such a problem. However, as the ...

Abstract With power grid heavy-load operation, and remote transmission distance which leads to voltage collapse, the method that combines continuous power flow (CPF) and improved differential evolution (IDE) algorithm is put forward to calculate a static voltage stability margin. First, we introduce mathematical model and CPF for solving the static voltage stability margin. And then, simulated ...

This paper presents a method concerning the integration of the benefit/cost analysis and the real genetic algorithm with various elements of reservoir dam design. The version 4.0 of HEC-RAS software and Hydro-Rout models have been used to simulate the region and flood routing in the reservoir of the dam, respectively. A mathematical programming has been prepared in MATLAB software and linked wi...

the objective of the present study was to evaluate the genetic structure and diversity of 16 generations of native fowls of west azerbaijan province, iran using the pedigree data collected between 1994 and 2012. inbreeding coefficient (f), pedigree completeness index (pci), parameters of the probability of gene origin and other parameters related to the genetic structure were estimated using th...

the purpose of this study was to compare various direct techniques of measuring attitudes toward risk. the equally likely certainty equivalent with a purely hypothetical risky prospect (elce-ph), the equally likely certainty equivalent with a hypothetical but realistic risky prospect (elce-r) and probability of winning demanded (pwd) models were used to elicit the risk attitude of a sample ...
