Introduction: The underlying mechanism responsible for the cardiovascular response to hemorrhage (HEM) is still unknown; however, several brain areas, such as the cuneiform nucleus (CnF) have shown to be involved. In this study, the cardiovascular effect of the CnF during HEM was evaluated. Methods: The animals were divided into the following groups: 1. Vehicle; 2. HEM; 3. Cobalt chloride (CoC...

A frequency domain dynamic analysis is needed to obtain the response of structures constructed on a system of base isolators on flexible soil when subjected to earthquake ground motion. In such systems, the lateral stiffness of the base isolators is so small, compared to the structural stiffness, that in an earthquake attack the fundamental vibration mode dominates the response. With this in mi...

The cortical hem, a source of Wingless-related (WNT) and bone morphogenetic protein (BMP) signaling in the dorsomedial telencephalon, is the embryonic organizer for the hippocampus. Whether the hem is a major regulator of cortical patterning outside the hippocampus has not been investigated. We examined regional organization across the entire cerebral cortex in mice genetically engineered to la...

BACKGROUND The Notch signaling pathway has been implicated in the pericyte phenotype, but its exact roles in hemangioma-derived pericytes (Hem-pericytes) remain ill defined. METHODS Hem-pericytes were stimulated by immobilized recombinant Jagged1. The potential mechanisms of Notch-induced Hem-pericytes growth arrest were investigated by cell cycle assay, and the role of the Notch in promoting...

With the increasing sensitivity and accuracy of contemporary high-performance electronic information systems to electromagnetic energy, they are also very vulnerable be damaged by high-energy fields. In this work, an all-dielectric field sensor is proposed based on a microring resonator structure. The designed work at 35 GHz RF using lithium niobate-on-insulator (LNOI) material system. 2.5-D va...

This thesis examines the effects of electromagnetic interference (EMI) and coupling in circuits and systems. The coupling phenomenon is investigated in nonuniform transmission lines and adjacent via structures in microelectronic circuits. Radiation from metallic enclosures with apertures and lined with resistive materials is analyzed. Electromagnetic interference on a larger scale is studied in...
