Two‐Step Clustering‐Based Equivalent Modeling of Large‐Scale Wind Farms for Enhanced Primary Frequency Regulation

Wind Energy
The focus on wind power frequency regulation has largely been on individual wind farms, which presents challenges in meeting the coordinated operation needs of multiple stations within large‐scale installations.

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

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.

Analysis of energy dissipation in resistive superconducting fault-current limiters for optimal power system performance

, 2011
Fault levels in electrical distribution systems are rising due to the increasing presence of distributed generation, and this rising trend is expected to continue in the future.

Adaptability analysis of distance protection in flexible low frequency ac outgoing transmission line of wind power system

Results in Engineering
The extension of offshore wind power to medium and far seas has promoted the development of flexible low-frequency AC transmission (FLFAC) technology. However, the fault responses of the power electronic interface-type power sources (wind turbines and ...

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

Molecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

Segmentation of the Sumatran fault

, 2014
Segmentation of the Sumatran fault is discerned using an analytical approach in which a k-means algorithm partitions earthquakes into clusters of seismicity along the fault.
