This letter proposes a multiobjective efficiency optimization method for triple-phase-shift (TPS) control of isolated dual active bridge converters (DABs). A comprehensive inductor current stress, rms current, and zero-voltage switching (ZVS) is presented to reduce conduction losses, magnetic losses. genetic algorithm used search optimal solutions the DAB nonconvex problem. Analysis these gives rise closed-form expressions optimum TPS angles, valid over various power voltage levels. These...
Abstract Head and neck squamous cell carcinoma (HNSCC) is the most common malignant tumor of head neck, incidence rate increasing year by year. Protein post-translational modification, recognized as a pivotal extensive form protein has been established to possess profound association with occurrence progression. This study employed bioinformatics analysis utilizing transcriptome sequencing data, patient survival clinical data from HNSCC establish predictive markers genes associated...
Electrically heated tobacco products (EHTPs) could release effective aerosol components from materials at relatively low temperatures without a burning phenomenon. It is essential to grasp the temperature distribution and mechanism of key in materials. The existing experimental studies have provided initial insights into thermodynamic behavior under various conditions. However, current numerical models are still their early stages development, with majority failing correlate heat transfer...
To study the wake development characteristics of wind farms in complex terrains, two different types Light Detection and Ranging (LiDAR) were used to conduct field measurements a mountain farm Hebei Province, China. Under incoming conditions, influence shear, terrain on trend was analyzed. The results showed that existence shear effect causes asymmetric distribution speed region. relief behind turbine indicated subsidence centerline, which had linear relationship with topography altitudes....
Purpose Due to the rarity of metaplastic breast carcinoma (MpBC), no randomized trials have investigated role combined chemotherapy and radiotherapy (CCRP) in this condition. We aimed explore identify effectiveness CCRP patients with regional lymph node metastasis (N+) non-metastatic MpBC. Materials Methods Data were obtained from National Cancer Institute’s Surveillance, Epidemiology, End Results (SEER) Program database. assessed effects on overall survival (OS), cancer-specific (BCSS),...
In this paper, for isolated bidirectional dual-bridge series resonant DC-DC converters (DBSRCs), the conditions wide-range zero-voltage switching (ZVS) under control of phase shift modulation (PSM) and variable frequency (VFM)are analyzed. For purpose accuracy, strategy is based on time-domain analysis instead fundamental harmonic approximation (FHA), in dead-band, changes inductor current also be considered. Meanwhile, load at different voltage gain, an improved given to fulfill...
The use of novel tobacco products that do not burn leaves is becoming increasingly popular worldwide. In terms respiratory system, smoking damage to the epithelial cells lung in urgent need attention and research. this study, we produced combustion cigarettes (CC) condensate from conventional heated (HTP) heat-not-burn (HNB) tobacco, determine nicotine other ingredients content respectively assessment CC HTP cytotoxicity after acute exposure cigarette smoke. We further select a toxicological...
<title>Abstract</title> Objectives: Heated tobacco products (HTPs) constitute a novel and emerging type of product. Actual puffing topography nicotine exposure studies are indispensable in risk assessment. In this study, we aimed to collect compare usage behavioural data on HTPs those conventional cigarettes (CCs) by recording the parameters users under laboratory conditions. Methods: Two hundred voluntary adult cigarette (164 male, 36 female) from 4 Chinese cities were recruited randomly...
The heated tobacco product (HTP) heats rather than burns to release an aerosol with significantly fewer toxicants conventional cigarette smoke and has received global attention in recent years. To investigate whether changes biomarkers of exposure could be detected after switching from cigarettes (CCs) HTPs, 224 subjects four cities China participated this study. Nine containing tobacco-specific nitrosamines (TSNAs), volatile organic compounds (VOCs), the for acrolein crotonaldehyde were...
As it is known, dual-bridge series resonant converters (DBSRCs) can achieve a relatively high efficiency by reducing the switching losses. In order to further improve performance of DBSRCs, significant minimize losses MOSFET and wire in coil winding PCB.
