Generalized Selection Bias and The Decomposition of Wage Differentials The major contribution of this paper is ending a new and flexible way to measure the effects of selection on log-wages. In this context, we offer a general approach to performing decomposition analysis when selection effects are present. We call the difference between unconditional and conditional expectations of the log-wag...

We study adaptation of a haploid asexual population on a fitness landscape defined over binary genotype sequences of length L. We consider greedy adaptive walks in which the population moves to the fittest among all single mutant neighbors of the current genotype until a local fitness maximum is reached. The landscape is of the rough mount Fuji type, which means that the fitness value assigned ...

The dynamics of a spin in the presence of a deterministic and a fluctuating magnetic field is solved for analytically to obtain the averaged value of the spin as a function of time for various kinds of fluctuations (noise). Specifically, analytic results are obtained for the time dependence of the expectation value of the spin, averaged over fluctuations, for Gaussian white noise, Gaussian colo...

The isolated fungi species of different kinds from chromium contaminated soil sites located in Nagalkeni, Chennai were used for reducing chromium(VI) in a tannery industry wastewater of Nagalkeni, Chennai.  The experiments were conducted to know biosorption potential of isolated fungi species for removing chromium(VI) in a tannery industry wastewater against the different pH, fungi biomass and ...

This Supplementary Information is organized as follows. Section II introduces two models of delay-based degradeand fire (DF) genetic oscillations in a single (negative feedback only) or dual (positive-negative feedback) systems. Section III contains the results of a deterministic analysis of the delayed negative feedback (NFB) system. Section IV examines stochastic oscillations in the NFB syste...

This paper presents an improvement of hybrid of nonlinear autoregressive with exogenous input (NARX) and autoregressive moving average (ARMA) for long-term machine state forecasting based on vibration data. In this study, vibration data is considered as a combination of two components which are deterministic data and error. The deterministic component may describe the degradation index of machi...

Given a graph G = (V, E) and a positive integer k, the PARTITION INTO CLIQUES (PIC) decision problem consists of deciding whether there exists a partition of V into k disjoint subsets V1, V2, . . . , Vk such that the subgraph induced by each part Vi is a complete subgraph (clique) of G. In this paper, we establish both the NP-completeness of PIC for planar cubic graphs and the Max SNP-hardness ...

System-level virtualization introduces critical vulnerabilities to failures of the software components that implement virtualization – the virtualization infrastructure (VI). To mitigate the impact of such failures, we introduce a resilient VI (RVI) that can recover individual VI components from failure, caused by hardware or software faults, transparently to the hosted virtual machines (VMs). ...

randomization is an essential component of sound clinical trials which prevents selection biases and helps in blinding the allocations. randomization is a process by which subsequent subjects enrolled into trial groups only by chance which is essentially eliminates selection biases. a serious consequence of randomization is severe imbalance among treatment groups with respect to some prognostic...

The first attempt to model a process is often a deterministic setup with differential equations. The existing stochastic influence is suppressed and hopefully negligible. However, sometimes the stochastic component is important. We demonstrate and clarify this for a growth process. The deterministic approach is given by Yn + 1 = Yn + g(Yn) or dYt = g(Yt)dt, Y0 = 1, g a positive function. The co...
