Anomaly Identification of Wind Turbine Yaw System Based on Two-Stage Attention–Informer Algorithm

Applied Sciences
In response to the problems that abnormal yaw position causes during the yawing process—on the one hand leading to the accumulation of yaw position errors, affecting the accuracy of yawing to the wind or safety due to excessive cable twisting, and on the

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.

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

Molecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Significant Suppression of High Electric Field Regions in XLPE via Voltage Stabilisers

High Voltage
Dielectric degradation typically originates from local defects. The resulting electric field concentration accelerates defect growth. Suppressing field distortion arising from such local weaknesses has long been a major challenge in electrical insulation.

Effect of Multiple Models of Closed-Loop Transfer Functions on Inter-Harmonic Oscillation Characteristics of Grid-Connected PMSG

CSEE Journal of Power and Energy Systems
Establishing a suitable closed-loop transfer function model for the grid-connected PMSG system is the key basis in performing inter-harmonic characteristics analysis. Multiple closed-loop transfer functions can be constructed when different components of

Analysis of China’s Regional Wind Power Generation Efficiency and its Influencing Factors

Chemical Engineering Transactions, 2018
In order to objectively evaluate the current situation of wind power generation in China and identify the key factors, based on the data of 30 Chinese provinces from 2011 to 2014, this study use a meta-frontier data envelopment analysis (DEA) model and a

Difference between grid connections of large-scale wind power and conventional synchronous generation

Global Energy Interconnection, 2020
In China, regions with abundant wind energy resources are generally located at the end of power grids. The power grid architecture in these regions is typically not sufficiently strong, and the energy structure is relatively simple.

A Multifractal Description of Wind Speed Records [PDF]

, 2004
In this paper, a systematic analysis of hourly wind speed data obtained from four potential wind generation sites in North Dakota is conducted. The power spectra of the data exhibited a power law decay characteristic of $1/f^{\alpha}$ processes with ...

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

Molecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...
