Collapse and Fragmentation of Rotating Magnetized Clouds. I. Magnetic Flux - Spin Relation

, 2005
We discuss evolution of the magnetic flux density and angular velocity in a molecular cloud core, on the basis of three-dimensional numerical simulations, in which a rotating magnetized cloud fragments and collapses to form a very dense optically thick ...

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Core Loss Analysis and Modeling of a Magnetic Coupling System in WPT for EVs

World Electric Vehicle Journal, 2021
The magnetic core is an important part of the magnetic coupling system in wireless power transmission (WPT) for EVs. It helps to increase the coupling coefficient and reduce magnetic field leakage. However, it also brings additional core loss.

Magnetar Oscillations II: spectral method

, 2011
The seismological dynamics of magnetars is largely determined by a strong hydro-magnetic coupling between the solid crust and the fluid core. In this paper we set up a "spectral" computational framework in which the magnetar's motion is decomposed into a

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

Molecular Oncology, EarlyView.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...

Optimization study on misalignment tolerance of a wireless power transfer system with double-layer vertical DD coils

Wireless Power Transfer
To address the issue of coil misalignment in magnetically coupled wireless power transfer (WPT) systems, which causes fluctuations in mutual inductance, a reduction in the magnetic coupling coefficient, and a decline in transmission efficiency, this ...

Multiscale modeling of magnetic distribution of ribbon magnetic cores [PDF]

CES Transactions on Electrical Machines and Systems, 2018
The multiscale finite element method (MsFEM) combined with conventional finite element method (CFEM) is proposed to solve static magnetic field in the ribbon magnetic core with non-periodical corners considered. Firstly, a simple 2-dimensional electrostatic problem is used to introduce the MsFEM implementation process.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Proposal of Fully Integrated LED Driver with Enhanced Power Density for Street-lighting Applications

Eletrônica de Potência
This paper proposes a new fully integrated Boost and Buck converter. The topology results from integrating the Boost as the power factor correction (PFC) stage and the Buck as power control (PC) stage.
