UWB Mixer improvement with Regulated Voltage Source
This paper presents a design of an UWB downconversion integrated CMOS resistive ring mixer with Linear Voltage Regulator (LVR), to supply required biasing voltages for the mixer section. The designed mixer circuit has been optimized for using in heart rate extraction system with microwave Doppler radar at 2.4GHz frequency. This mixer needs 2 DC bias voltages equal to 0.5 and 1 volts for its bes...
متن کاملVascular Endothelial Growth Factor Production is Regulated by Gene Polymorphisms
Background: Vascular endothelial growth factor (VEGF) has a key role in angiogene-sis and in transplantation. The level of VEGF is related to the differences in the DNA sequence of its promoter region. Objectives: In this study, the association between the combination of VEGF –1154 G and –2578 C alleles and VEGF production by LPS-stimulated PBMCs was investigated. In addition; the relationship ...
متن کاملThymocyte Differentiation is Regulated by a Change in Estradiol Levels during the Estrous Cycle in Mouse
Recent study showed that T cells in the immune organs and peripheral blood are influenced by estradiol, leading to a dysfunction of the immune system. However, little is known about the thymic-gonadal relationship during the estrous cycle in mouse. Therefore, the purpose of this study was to elucidate the mechanism by which a change in estradiol levels during the estrous cycle regulates the dev...
متن کاملSelf-Organizing Global Gene Expression Regulated Through Criticality: The Mechanism of Cell Fate Change
Background A fundamental issue in bioscience is to understand the underlying mechanism of the dynamic control of genome-wide expression through the complex temporal-spatial selforganization of the genome regulating cell fate change. We address this issue by elucidating a physically motivated self-organizing mechanism. Principal Findings Building upon transcriptome experimental data for seven di...
متن کاملA Behavior Change Perspective on Self-Regulated Learning with Teachable Agents
Producing lasting changes to metacognition, or the more encompassing construct of self-regulated learning (SRL), has strong parallels to producing behavior change. In the former case, the goal is to develop new “habits of mind,” and in the latter, the goal is to develop new “habits of behavior.” The techniques and theories of behavior change can inform the design of instruction intended to supp...
