Research on the Magnetostrictive Characteristics of Transformers under DC Bias

open access: yes, 2023
Direct current (DC) bias leads to increased vibration and noise in transformers. One of the main causes is the magnetostrictive effect of the transformer core.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Calculation and control of DC bias current distribution in an AC power system around a typical ±800 kV DC grounding electrode

open access: yesThe Journal of Engineering, 2019
When the ultra-high-voltage direct current (UHVDC) transmission system operates in a monopolar ground return mode, an enormous DC current flows into earth via the DC grounding electrode in the converter station and then comes into the AC system around ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

DC-DC transformer multiphase converter with transformer coupling for two-stage architecture

open access: yes2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010
This paper presents an analysis of a very high efficiency topology based on a multiphase converter where the coupling among the phases is done by means of transformers. Since energy is not stored in the transformers, it is transferred directly from the input to the output. This topology along with its control strategy, were previously reported in state

Design of high voltage and large capacity DC transformers based on capacitive power transfer principle

open access: yesZhejiang dianli
DC transformers serve as critical infrastructure for interconnecting DC systems at different voltage levels and constructing DC power grids. The development of cost-effective, high-efficiency, and lightweight DC transformers remains a pivotal research ...

Modular High-Frequency High-Power Transformers for Offshore Wind Turbines

open access: yes, 2021
Conventional line frequency transformers are commonly used for wind turbines to step up the low-level voltage of the generators to reduce the transmission losses.

DNA methylation and expression of MAPRE3 affect overall survival of early‐stage non‐small cell lung cancer patients

open access: yesMolecular Oncology, EarlyView.
Both cg12821679MAPRE3 methylation and MAPRE3 expression are significantly associated with overall survival (OS) of non‐small cell lung cancer. Meanwhile, MAPRE3 expression significantly modified the effect of smoking cessation on OS. Smoking cessation benefits OS merely for patients with high MAPRE3 expression.

A versatile series‐parallel‐connected bidirectional DC power flow controller for HVDC and MVDC system

open access: yesIET Generation, Transmission & Distribution, 2023
This paper proposes a transformer type dc power flow controller (DCPFC) based on stacks composed of sub‐modules (SMs). The converter can perform dc power flow control independently on point‐to‐point as well as multi‐terminal connection, which can be ...

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

open access: yesFEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.
