Generalized extreme shock models with a possibly increasing threshold [PDF]

, 2010
We propose a generalized extreme shock model with a possibly increasing failure threshold. While standard models assume that the crucial threshold for the system may only decrease over time, because of weakening shocks and obsolescence, we assume that ...

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Influence of skew and cross-coupling on flux-weakening performance of permanent-magnet brushless AC machines [PDF]

, 2009
A method is proposed for predicting the flux-weakening performance of permanent-magnet (PM) brushless ac machines accounting for skew and d-q axis cross-coupling.

RIPK4 function interferes with melanoma cell adhesion and metastasis

Molecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Permanent Magnet Rotor Flux Linkage Control Through Direct Axis Field Amplification

IEEE Open Journal of Industry Applications
Permanent magnets are popular for electric vehicle rotors due to their high energy density, making them excellent candidates for high-torque and high-speed machines. The downside of a permanent magnet machine is the inability to regulate the rotor field,

Field exposed water in a nanopore: liquid or vapour?

, 2008
We study the behavior of ambient temperature water under the combined effects of nanoscale confinement and applied electric field. Using molecular simulations we analyze the thermodynamic causes of field-induced expansion at some, and contraction at ...

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Towards the efficiency transportation work of locomotives diesel traction in real operating conditions [PDF]

E3S Web of Conferences
A methodology for substantiating the optimal parameters settings of diesel generators of diesel locomotives according to the criterion of the maximum weighted average efficiency of a diesel locomotive depending on their operating conditions is presented,

Deadbeat predictive current control of PMSM drives with an adaptive flux‐weakening controller

IET Power Electronics, 2022
In practical application, the motor speed may need to be greater than the rated speed, so field‐weakening control is required. However, the conventional flux‐weakening control requires much tuning work, because multiple PI controllers are used.

Stochastic Properties of Static Friction [PDF]

, 2020
The onset of frictional motion is mediated by rupture-like slip fronts, which nucleate locally and propagate eventually along the entire interface causing global sliding.
