Implementation of a Phase Shifted Full bridge DC-DC ZVS converter with peak current mode control [PDF]

, 2019
In this thesis a 600W Phase-Shifted Full-Bridge DC-DC ZVS converter using peak current mode control has been designed and implemented. Aspects of the hardware implementation of an isolated SMPS, such as electromagnetic interference, high voltage ...

Unique circulating miRNAome signatures captured with distinct molecular states in Lynch syndrome and sporadic colorectal cancer

Molecular Oncology, EarlyView.
Circulating microRNA profiles distinguish nonmalignant Lynch syndrome from cancer‐associated Lynch syndrome, sporadic colorectal cancer, and healthy controls. Age‐stratified analysis reveals disease‐specific regulatory states, and a six‐miRNA panel shows concordant separation in an independent colorectal tissue cohort.

A Detailed Full-Order Discrete-Time Modeling and Stability Prediction of the Single-Phase Dual Active Bridge DC-DC Converter

IEEE Access, 2022
The standard methodology to obtain the model of a power electronic converter is achieved by averaging the state-space dynamics of the converter’s state variables.

An outer membrane vesicle‐associated two‐track model for enterotoxigenic Bacteroides fragilis oncogenesis

Molecular Oncology, EarlyView.
Enterotoxigenic Bacteroides fragilis is a gut bacterium linked to bowel cancer. We propose that its toxin acts along two routes: at the cell surface, cutting the adhesion protein E‐cadherin and triggering inflammation; and inside the cell, delivered by bacterial vesicles, switching on NOD1 and cancer stem cell programs.

Hybrid DC–DC Converter With Novel Clamp Circuit in Wide Range of High Output Voltage

IEEE Access
In this paper, a hybrid converter with a novel clamp circuit is introduced. This hybrid converter integrates a phase-shifted full-bridge (PSFB) converter with a half-bridge (HB) LLC converter. On the primary side, the lagging leg of the PSFB converter is

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Circulating Current-less Phase-Shifted Full-Bridge Converter With New Rectifier Structure

, 2018
A conventional phase-shifted full bridge (PSFB) converter has several advantages for high power applications since it has full-bridge structure and all switching devices can achieve soft switching.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

A tunable WDM wavelength converter based on cross phase modulation effects in normal dispersion holey fiber

, 2003
We demonstrate a tunable wavelength-division-multiplexing wavelength converter based on cross-phase modulation in just 5.8m of highly nonlinear normal dispersion holey fiber (HF) and incorporating a precise compression-tuned apodized fiber-grating filter.
