A Review of Research Methods for Stator Temperature Monitoring in PMSM

CES Transactions on Electrical Machines and Systems
High-density permanent magnet synchronous motors (PMSMs) are widely used in electric drive systems. However, they are susceptible to temperature influences under complex operating conditions, and prolonged operation at high temperatures can first damage ...

The \HI column density power spectrum of six nearby spiral galaxies

, 2013
We propose a method to determine the power spectrum of \HI column density fluctuations using radio-interferometric observations of 21-cm emission from the ISM of galaxies.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Thrust Ripple Analysis and Precise Modeling of 12/13 Slot-Pole Linear Flux-Switching Permanent Magnet Motors

CES Transactions on Electrical Machines and Systems
Linear flux-switching permanent magnet motors (LFSPMs) have been proposed for long stator applications such as rail transit. However, the conventional linear permanent magnet synchronous motor (LPMSM) suffers from thrust ripple, which degrades the motor ...

Antenna/Body Coupling in the Near-Field at 60 GHz: Impact on the Absorbed Power Density

Applied Sciences, 2020
Wireless devices, such as smartphones, tablets, and laptops, are intended to be used in the vicinity of the human body. When an antenna is placed close to a lossy medium, near-field interactions may modify the electromagnetic field distribution. Here, we

Water immersion cooling of high power density electronics

, 2020
Thermal management of power electronic systems is a key bottleneck to power densification. Single phase cooling is limited to low heat transfer coefficients ( μ m in preventing current from leaking between the electronic components and the surrounding ...

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

Coulomb gap in one-dimensional disordered electron systems

, 2002
The density of states of one-dimensional disordered electron systems with long range Coulomb interaction is studied in the weak pinning limit. The density of states is found to follow a power law with an exponent determined by localization length, and ...
