To expand the applicability of noise-immune cavity-enhanced optical heterodyne molecular spectrometer (NICE-OHMS), a universal system incorporating fiber-coupled single-sideband modulator (f-SSM) for control laser frequency has been developed. A homemade PID servo mainly composed two integrators designed, resulting in locking bandwidth 170 kHz and continuous tuning range 2.2 GHz. The exhibits n...
this paper presents a comparative analysis between two current control strategies, constant source power and generalized fryze current, used in active power filter (apf) applications having three different modulation methods. the hysteresis band (hb) and first-order delta-sigma modulation (dsm) as well as the second-order dsm is applied. the power section of the active power filter is viewed as...
The unfavorable effects of neonatal immunodeficiency are limited by some naturally occurring compensatory mechanisms, such as the introduction of protective and immunological components of human milk in the infant. Breast-feeding maintains the maternal-fetal immunological link after birth, may favor the transmission of immunocompetence from the mother to her infant, and is considered an importa...
Aberrant immune responses represent the underlying cause of central nervous system (CNS) autoimmunity, including multiple sclerosis (MS). Recent evidence implicated the crosstalk between coagulation and immunity in CNS autoimmunity. Here we identify coagulation factor XII (FXII), the initiator of the intrinsic coagulation cascade and the kallikrein-kinin system, as a specific immune cell modula...
A new structure is presented for digital delta-sigma modulator (DDSM). Novel architecture decreases hardware consumption, output quantization noise and spurs in Comparison to previous architectures. In order to reduce the delay, power consumption and increase maximum working frequency, the pipelining technique and the carry skip adder are used. Simulation proposed architecture shows that the qu...
The cholinergic nervous system attenuates the production of pro-inflammatory cytokines and inhibits inflammatory processes. Hence, in animal models of intestinal inflammation, such as postoperative ileus and dextran sulfate sodium-induced colitis, vagus nerve stimulation ameliorates disease activity. On the other hand, in infectious models of microbial peritonitis, vagus nerve activation seemin...
This review is focused on the hypothesis that hypnosis can differentially modulate T-cell subsets and that this effect is mediated by changes in hypothalamo-pituitaryadrenal (HPA) mediators, such as cortisol. Psychoneuroimmunology (PNI) is the study of the interaction between psychological processes and the nervous and immune systems, taking an interdisciplinary approach including psychology, n...

Abstract INTRODUCTION Malignant gliomas consist of heterogenous cellular components that have adopted multiple overlapping escape mechanisms overcome both targeted and immune-based therapies. The receptor for advanced glycation end products (RAGE) is a member the immunoglobulin superfamily activated by diverse proinflammatory ligands present in tumor microenvironment (TME). Activation RAGE its ...
