Action potentials can be recorded extracellularly from hundreds of neurons simultaneously with multi-electrode arrays. These can typically have as many as 120 or more electrodes. The brief duration of action potentials requires a high sampling frequency to reliably capture each waveform. The resulting raw data files are therefore large and difficult to visualize with traditional plotting tools....

This study, undertaken as a component of the global Dracunculiasis Eradication Program (DEP), was designed to provide molecular tools to distinguish Dracunculus medinensis, the nematode causing human dracunculiasis, from other tissue-dwelling nematodes, including other Dracunculus species that infect humans and other animals. DNA was extracted from D. medinensis and from a closely related speci...

We investigate the disciplining role of debt in the publicly held firm by examining the relation between employee productivity and financial leverage. The unique feature of our study is that we incorporate outside employment opportunities for employees into the analysis. Consistent with the notion that the debt serves as a bonding mechanism because agents exert additional effort to avoid the pe...

This study uses kernel k-means cluster analysis to identify medical staffs with high burnout. The data collected in October to November 2014 are from the emotional exhaustion dimension of the Chinese version of Safety Attitudes Questionnaire in a regional teaching hospital in Taiwan. The number of effective questionnaires including the entire staffs such as physicians, nurses, technicians, phar...

High-density microelectrode arrays (HDMEA) have been recently introduced to study principles of neural function at high spatial resolution. However, the exact nature of the experimentally observed extracellular action potentials (EAPs) is still incompletely understood. The soma, axon and dendrites of a neuron can all exhibit regenerative action potentials that could be sensed with HDMEA electro...

A determinação de enxofre por espectrometria de massa com plasma acoplado indutivamente (ICP-MS) não é trivial, especialmente devido a intensas interferências espectrais causadas por íons poliatômicos como O2 , (OH)2 , NOH2 + e NO. Neste trabalho, espécies de argônio naturalmente presentes no plasma (padrões de interferência, IFS) são usadas para minimizar interferências espectrais na determina...

The increasing domination of English as the world's leading medium of international professional communication has begun to impact English for Academic Purposes programs. Specifically, questions arise as to whether English is becoming too successful. This paper reviews several of the resulting ideological challenges to EAP. Although not all of these challenges are accepted as well-founded, the ...

OBJECTIVE The purpose of this study was to compare the effects of high-concentration contrast material and low-voltage CT simulated by virtual monochromatic (VM) imaging on contrast enhancement at multiphasic CT of the upper abdomen. METHODS This study included 72 patients who underwent CT during early arterial (EAP), late arterial and portal venous phases after 300-mgI/ml (Group A; 34 patien...

In ord.er to further improve the quality of hospital based long term contracepîive services (ILID, implant, and' sterilization) in a more systematic and continous way in Ind.onesia, a Quality Assurance Program (QA) was introduced in twelve selected hospitals in Jakarta that had. family planning programs. This stud.y was conducted in order to determine which factors influence the implementation ...

AIMS The main aim of this longitudinal study was to test the Job Demand-Control-Support (JDCS) model and to analyze whether changes in psychosocial job characteristics are related to (changes in) burnout. BACKGROUND Previous studies on the effects of JDCS variables on burnout dimensions have indicated that the iso-strain hypothesis (i.e., high job demands, low control, and low support additiv...
