OBJECTIVE To examine the properties and potential clinical uses of myogenic potentials to bone conducted sound. METHODS Myogenic potentials were recorded from normal volunteers, using bone conducted tone bursts of 7 ms duration and 250-2000 Hz frequencies delivered over the mastoid processes by a B 71 clinical bone vibrator. Biphasic positive-negative (p1n1) responses were recorded from both ...

In 1994, an international group of interested clinicians and biostatisticians met to discuss the design of clinical trials in herpes zoster. They agreed that trials in herpes zoster should have prospectively agreed definitions of all outcome measures and plans for data analysis. In immunocompetent individuals, in whom pain is the major outcome measure, trials should only include patients over t...

Bone-conducted speech is of low intelligibility, but its quality is not affected by noise. In this paper, we take into account such propertes of bone-conducted speech, and address a digital filter to reconstruct the quality of the bone-conducted speech signal obtained from a speaker. The reconstruction filter design method is derived based on a model assumption of pronunciation. Experimental re...

An emphasis on research was established with the 1998 Council on Accreditation of Nurse Anesthesia Educational Programs (COA) requirement that all nurse anesthetists graduate with a master's level of education. Nursing research is essential to expand the profession's knowledge base and to establish a foundation for evidence-based practice. However, to date there are no existing data indicating ...

This project explores quadratic residues, a classical number theory topic, using computational techniques. First I conducted computational experiments to investigate the distribution of quadratic residues modulo primes, looking for patterns or evidence against randomness. The experimental data indicates a non-random distribution of quadratic residues. Certain features of such non-random distrib...

Conducted vasodilation is part of the physiological response to increasing metabolic demand of the tissue. Similar responses can be elicited by focal electrical or chemical stimulation. Some evidence suggests an endothelial pathway for nondecremental transmission of hyperpolarizing pulses. However, the underlying mechanisms are debated. Here, we focus on dynamical aspects of the problem hypothe...

The Conformal Computing (CC) program is a partnership between the NDSU Center for Nanoscale Science and Engineering (CNSE) and the MIT Center for Bits and Atoms (CBA). The Phase II period of performance commenced on September 1, 2007, and concluded October 31, 2008. This document reports on the research conducted at CNSE. The work done at CBA is reported in companion documents. Also chronicling...

Research on juvenile Pacific salmon in coastal U.S. waters began almost 50 years ago in Southeast Alaska, and has continued somewhat sporadically since then. The National Marine Fisheries Service (NMFS), through its various laboratories in Alaska and along the West Coast of the United States, has done much of the research on the early life history of many Pacific salmon stocks in all habitats o...

PURPOSE To reduce antigenicity of allografts and stimulate their replacement by natural recipient tissues. METHODS Experimental allotransplantation of different tissues (fascias, tendons, derma, fat, etc.) with histological, histochemical, electron microscopical, electron histochemical examination 3, 5, 7, 14, 21, 30, 60, 120, 180 and 360 days postoperatively. RESULTS Allografts of differen...
