During the last two decades, Maximum Likelihood estimation (ML) has been used to determine Direction Of Arrival (DOA) and signals propagated by the sources, using narrowband array signals. The algorithm fails in the case of wideband signals. As an attempt by the present study to overcome the problem, the array outputs are transformed into narrowband frequency bins, using short time Fourier tran...

The rete mirabile of Hippopodius (Cl. Hydrozoa, O. Siphonophora) is a sheet of giant endoderm cells penetrated by branches of the ventral radial canal. The cells appear to be highly polyploid. The rough ER is very richly developed and expanded ER cisternae containing amorphous material (presumably synthesized protein) are observed near the outer cell surface. The cells are electrically coupled,...

LONG-TERM GOALS The feasibility of using focused shock waves for mine neutralization requires detailed understanding of nonlinear wave propagation in water. This project investigates several fundamental issues of nonlinear acoustics when the primary source configuration is a discrete array of intense sources. Questions addressed through the theoretical analysis and an experimental effort concer...

While seed-propagated crops have contributed many evolutionary insights, evolutionary biologists have often neglected clonally propagated crops. We argue that widespread notions about their evolution under domestication are oversimplified, and that they offer rich material for evolutionary studies. The diversity of their wild ancestors, the diverse ecologies of the crop populations themselves, ...

Background: The undergraduate science, technology, engineering, and mathematics (STEM) education community has developed a large number of innovative teaching strategies and materials, but the majority of these go unused by instructors. To help understand how to improve adoption of evidence-based education innovations, this study focuses on innovations that have become widely used in college-le...

Propagated vasodilation has been observed in the peripheral vasculature and may be significant in integrating the behavior of terminal arterioles and larger vessels. We have studied the characteristics of propagated vasodilation induced by acetylcholine in the microcirculation of the cheek pouch of the golden hamster. The technique of microionophoresis was used as a means of achieving relativel...

Scaling phenomena of the Internet traffic gain people’s interests, ranging from computer scientists to statisticians. There are two types of scales. One is small-time scaling and the other large-time one. Tools to separately describe them are desired in computer communications, such as performance analysis of network systems. Conventional tools, such as the standard fractional Brownian motion f...

In this paper, we first provide a new theoretical understanding of the Evidence Pre-propagated Importance Sampling algorithm (EPIS-BN) (Yuan & Druzdzel 2003; 2006b) and show that its importance function minimizes the KL-divergence between the function itself and the exact posterior probability distribution in Polytrees. We then generalize the method to deal with inference in general hybrid Baye...

Mouse mammary tumor viruses (MMTV) from three different strains of mice have been used to establish productive infections in feline and mink cell lines. The virions that are released by these cells compete completely in a radioimmunoassay for the major virion surface glycoprotein of MMTV (gp52), thus demonstrating that antigenic determinants of gp52 are viral coded. Competitive molecular hybrid...
