Research on IGBT junction temperature model based on united-parameters

Energy Reports, 2020
The insulated gate bipolar transistor (IGBT) is the most expensive central component in the converter interior, but it is also one of the most vulnerable to failure. The failure of power electronic system is mainly due to temperature change.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Research on Equivalent Circuit Model of HVDC Valve and Calculation of Thyristor Junction Temperature

Active and Passive Electronic Components
For the difference of thyristor junction temperature at all levels in the transducer valve assembly in the series water circuit, an equivalent model of thyristor junction temperature calculation for the valve assembly is established, and PLECS simulation

THE EFFECT OF TEMPERATURE ON THE NEUROMUSCULAR JUNCTION OF THE FROG

The Japanese Journal of Physiology, 1958
1. The effect of temperature on the neuromuscular transmission of the frog's sartorius muscle was studied, with the intracellular electrode, at temperatures between 10°C. and 20°C.2. The end-plate potential diminished, in general, in amplitude as the temperature was lowered. The rate of change in the amplitude was large in the condition that the output

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Modeling and Analysis for Estimation of Junction Temperature Under Various Operating Conditions and Optimization of Pin-Fin Heat Sink for Automotive IGBT Modules

Applied Sciences
New energy vehicles (NEVs) rely heavily on Insulated-Gate Bipolar Transistors (IGBTs) to perform frequent battery voltage conversions for operations such as acceleration, deceleration, and hill climbing.

Optical determination of the junction temperature of OLEDs [PDF]

Organic Electronics, 2013
Abstract This paper describes a novel optical measurement technique for the in situ determination of the spatial temperature distribution at the organic layer level in large-area organic light-emitting diodes (OLEDs). The local junction temperature of OLEDs is a very important factor with respect to the luminance uniformity. Moreover the variation of

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
