The term “data surveying” refers to the preliminary examination of a dataset to assess its overall character, and this process typically involves simple descriptive statistics to characterize the available variables, along with detection of data anomalies (e.g., outliers or incomplete records) and possibly other “interesting” or “unusual” features that may be worthy of careful scrutiny. In the ...

A highly sensitive fourth derivative spectrophotometric method is presented for the residue analysis of ethylenebis dithiocarbamate fungicide Maneb. The fungicide maneb forms a blue complex with sodium molybdate on heating which is studied spectrophotometrically. The method has been successfully applied to maneb determination in wheat grains and soft drinks with high recoveries. The analytical ...

Outliers have more than two centuries’ history in the field of statistics. Recently, they have become a focal topic because of their relevance to terrorism, network intrusions, financial fraud, and other areas where rare events are critical to understanding a process. This paper presents a new algorithm, called hdoutliers, for detecting multidimensional outliers. It is unique for a) dealing wit...

Abstract Background A simple indicator of technical efficiency, such as productivity health workers, measured using routine facility data, can be a practical approach that inform initiatives to improve efficiency in low- and middle-income countries. This paper presents proof concept information from primary healthcare (PHC) facilities measure workers’ its application three regions Ethiopia. Met...

Cover: Scanning electron micrograph of 7-day-old colony of powdery mildew (Blumeria graminis f.sp. tritici) on a wheat leaf. Insert shows a 2-day-old colony at higher magnification. Although the sensitivity of mildew populations towards certain fungicides has changed considerably over the years, implementation of resistance management strategies has helped to sustain an overall satisfactory deg...

cannot be inhibited (hence its attraction as a memory maintenance molecule); however, pharmacological inhibitors of PKMz are available. Many studies have now shown that inhibition of PKMz appears to erase consolidated memories, as well as established LTP [18]. But not all forms of consolidated memories are susceptible to disruption by inhibition of PKMz [19]. Furthermore, the specificity of the...

Background At present, the diagnosis-related groups-based prospective payment system (DRG-PPS) that has been implemented in China is merely a prototype called the simplified DRG-PPS, which is known as the 'ceiling price for a single disease'. Given that studies on the effects of a simplified DRG-PPS in China have usually been controversial, we aim to synthesize evidence examining whether DRGs c...

Functional and biophysical constraints result in site-dependent patterns of protein sequence variability. It is commonly assumed that the key structural determinant of site-specific rates of evolution is the Relative Solvent Accessibility (RSA). However, a recent study found that amino acid substitution rates correlate better with two Local Packing Density (LPD) measures, the Weighted Contact N...

CONTEXT Chronic starvation is characterized by GH resistance, and obesity is characterized by decreased GH secretion. In both extremes, IGF1 levels may be low and androgen levels may be abnormal. OBJECTIVE To investigate the determinants of IGF1 and GH across the weight spectrum in women. DESIGN Cross-sectional study. SETTING Clinical research center. STUDY PARTICIPANTS In total, 32 wom...

Rationale Fungicide applications are a necessary practice to discourage disease development in most high quality turfgrass areas. Little is known, however, about the effects that fungicides have on resident microbial community of the soils supporting turfgrass sites. Soil bacteria are responsible for important processes including pesticide degradation, nutrient cycling, and organic matter break...
