BACKGROUND H(2)S synthesis inhibitors (HSSI) have been shown to impact respiratory control. For instance, the HSSI hydroxylamine (HA) decreases the respiratory discharge rate from isolated medullary sections, and HA in addition to other HSSIs propargylglycine and amino-oxyacetic acid (AOAA) have been found to reduce hypoxic responsiveness. OBJECTIVES The aim of this study was to determine if ...

The system-level protocol verification of a high-end FPGA with an embedded high-speed serial interface (HSSI) poses challenges that are comparable to and arguably exceed those encountered in ASIC-like verification flows. A single high-end FPGA device with embedded transceivers is designed to provide dedicated hard intellectual property (IP) support for a wide range of industry protocols and app...

background: heat stress is a common and usual problem in industries. several indices, including wet bulb globe temperature (wbgt), are used to evaluate heat stress. however, wbgt index has limitations such as high cost and response time. it is not thus suitable as a screening tool. heat strain scoring index (hssi) is also an observational-judgmental technique that has been developed for primary...

SRI International has investigated the feasibility of measuring representative toughness values for nuclear pressure vessel materials using small cracked round bars (CRBs). We tested a weldment material [Heavy-Section Steel Irradiation (HSSI) Weld 72W with 0.23% copper] at six temperatures (-150%, -800, -500, 00, 230, and 50'C) using CRBs and compared the fracture-toughness results with data ob...

A technique for building a three-dimensional description of a static scene from a spatiotemporal image is presented. This technique utilizes Homocentric Spherical Spatiotemporal Image (HSSI) analysis and makes allowances for camera rotation, which is a wider class of camera motion than that in ordinary spatiotemporal image analysis. Experiments with real images from a translating and rotating c...
