The sedimentation and diffusion coefficients have been determined for Hemophilus influenzae transforming activity and DNA using P(32)-labeled DNA. The methods employed the Spinco fixed boundary separation cell for measurements of the sedimentation coefficient and the Northrop-Anson diffusion cell to determine the diffusion coefficient. There was a very close correlation between the amount of DN...

Asynchronous Parallel Evolutionary Algorithms (HAPEAs) have shown to be robust as they require no derivatives or gradients of the objective function, have the capability of finding globally optimum solutions amongst many local optima, can be executed asynchronously in parallel and adapted easily to arbitrary solver codes without major modifications. The application of the methodology is illustr...

Plasmid Mor174 has a molecular weight of 3.6 X 10(6) and a buoyant density of 1.6994 g/cm3. The covalently closed circular form has a sedimentation coefficient of 22S. These are 30 to 40 plasmid copies per genome equivalent, but growth in chloramphenicol results in amplification of the copy number to 600. In Proteus morganii 174, Mor174 coexists with a cryptic plasmid of molecular weight 15.8 X...

INTRODUCTION This study explores the associations of weight perceptions with actual body mass index (BMI) and attempts to lose weight in a nationally representative sample of a pediatric population. MATERIAL AND METHODS Data were collected from school students of 27 provinces in Iran, as part of "the national survey of school student high risk behaviors". We used t-test for continuous data an...

BACKGROUND Childhood obesity is a continuing problem in the UK and South Asian children represent a group that are particularly vulnerable to its health consequences. The relationship between body dissatisfaction and obesity is well documented in older children and adults, but is less clear in young children, particularly South Asians. A better understanding of this relationship in young South ...

In this paper, a cooperative sensing algorithm for OFDM is proposed in this paper based on the performance analysis of ONPD algorithm, then the system weight vector is optimized and the closed form expression of optimal weight vector is obtained using the maximum improved deflection coefficient. Theoretical analysis and simulation results demonstrate the remarkable improvement of proposed algor...

The eigenvalues of linear, regular, two point boundary value problems depend continuously on the problem. In the important self-adjoint case studied by Naimark and Weidmann this dependence is differentiable and the derivatives of the eigenvalues with respect to a given parameter: an endpoint, a boundary condition, a coefficient, or the weight function, are found. Monotone properties of the eige...

OBJECTIVE This study aimed to compare self-reported weight and body mass index (BMI) in order to determine discrepancies between subjective and objective obesity-related markers, and possible explanatory factors of overweight and obesity underestimation, in urban, rural and migrant populations. MATERIALS AND METHODS Data from the PERU MIGRANT study, a cross-sectional study, in low-income sett...

A pressure-sensitive paint (PSP) with fast response characteristics that can be sprayed on a test article is studied. This PSP consists of a polymer for spraying and a porous particle for providing the fast response. We controlled the polymer content (%) from 10 to 90% to study its effects on PSP characteristics: the signal level, pressure sensitivity, temperature dependency, and time response....

A novel adaptive weight online sequential extreme learning machine (AWOS-ELM) is proposed for predicting time series problems based on an online sequential extreme learning machine (OS-ELM) in this paper. In real-world online applications, the sequentially coming data chunk usually possesses varying confidence coefficients, and the data chunk with a low confidence coefficient tends to mislead t...
