The K-coverage configuration that guarantees coverage of each location by at least K sensors is highly popular and is extensively used to monitor diversified applications in wireless sensor networks. Long network lifetime and high detection quality are the essentials of such K-covered sleep-scheduling algorithms. However, the existing sleep-scheduling algorithms either cause high cost or cannot...

Test system for Aero Hydraulic Pump (AHP) has many nonlinear characteristics. Take two control strategies, Neural Network Controller (NNC) and Passivity Based Controller (PBC), to control the speed of AHP for measuring its properties. The results gained from comparing and analyzing to these controllers show that under different outlet pressures of AHP PBC has good stability and robustness which...

The intrarenal dopamine system is important for signaling and natriuresis, and significant dysfunction is associated with hypertension and kidney disease in ex vivo studies. Dopamine receptors also modulate and are modulated by the renin-angiotensin-aldosterone system. Here, we show the first in vivo measurement of D1-like receptors in the renal cortex of Sprague-Dawley rat and Papio anubis bab...

AIMS Percutaneous coronary intervention (PCI) is increasingly being used to treat left main stem (LMS) coronary artery disease. Disease at the LMS bifurcation is technically challenging to treat, and there is no consensus as to the best method. We previously described experimental and initial clinical results with the simultaneous kissing stents (SKS) technique in a small series using drug-elut...

The Microwave Humidity and Temperature sounder (MWHTS) on board the Fengyun (FY)-3C satellite measure the outgoing radiance form the Earth surface and atmospheric constituents. MWHTS makes measurements in the isolated oxygen absorption line near 118 GHz and the vicinity of strong water vapor line around 183 GHz, can provide fine vertical distribution structure of both atmospheric humidity and t...

[1] In this study, we analyzed the seismic phases S, SKS, and SKKS from 31 deep-focus earthquakes in the Tonga-Fiji region recorded in North America between epicentral distances of 85 and 120 . The differential traveltimes and amplitude ratios for these phases reveal clear epicentral distance trends not predicted by standard one-dimensional (1-D) reference Earth models. The increase of the S/SK...

This article presents an overview of a strategy for assignment of hazard-specific skin notations (SK), developed by the National Institute for Occupational Safety and Health (NIOSH). This health hazard characterization strategy relies on multiple SKs capable of delineating systemic (SYS), direct (DIR), and immune-mediated (SEN) adverse effects caused by dermal exposures to chemicals. One advant...

The k-nearest neighbor classification method (kNNC) is one of the simplest nonparametric classification methods. The mutual k-NN classification method (MkNNC) is a variant of k-NNC based on mutual neighborship. We propose another variant of k-NNC, the symmetric k-NN classification method (SkNNC) based on both mutual neighborship and one-sided neighborship. The performance of MkNNC and SkNNC dep...
