GENERAL FAULT ADMITTANCE METHOD LINETO- LINE-TO-LINE UNSYMMETRICAL FAULT [PDF]

open access: yesJournal of Engineering Science and Technology, 2015
Line-to-line-to-line unsymmetrical faults either involving or not involving ground are in the classical fault analysis approach difficult to analyse.

An improved Hausdorff distance method for locating single phase to ground fault in neutral non‐effectively grounded system

open access: yesIET Generation, Transmission & Distribution, 2021
Neutral non‐effectively grounded mode is widely used in medium‐voltage distribution networks in China. When a single‐phase grounding fault occurs in distribution networks, abundant transient signals will be generated.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Research of Fault Line Selection Method of Distribution Network Based on Transient Zero-sequence Energy

open access: yesGong-kuang zidonghua, 2012
For problem of ineffectiveness of traditional line selection methods by use of single feature value caused by complex and random fault borderline, small steady component of fault and reverse phase of instantaneous zero-sequence power when single-phase ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Characteristics and Control Strategy of Cascaded SVG with Star-configuration Considering Negative-sequence Compensation

open access: yesKongzhi Yu Xinxi Jishu, 2013
This paper illustrated var and negative sequence comprehensive compensation principles of cascaded static var generator(SVG) with star-configuration. The mathematical expression of zero-sequence voltage was deduced, and subsequently zero-sequence voltage

Mixed-frequency Cascaded H-bridge SVG Ripple Suppression Method

open access: yesJournal of Harbin University of Science and Technology
To address the DC-side inter-phase voltage imbalance in star-configured cascaded H-bridge static var generator (SVG) under grid unbalanced faults in new power systems, a ripple suppression method combining a hybrid-frequency topology with triple ...

Fuzzy comprehensive line selection method of resonance grounding fault in coal mine

open access: yesGong-kuang zidonghua, 2015
For failure of fault line selection methods based on steady-state component in resonance grounding system, three kinds of methods were analyzed from the perspective of transient component including zero-sequence energy method, wavelet transform method ...

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

open access: yesMolecular 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.

Single‐cell DNA methylation profiling: Technologies, computation, and applications in precision oncology

open access: yesMolecular Oncology, EarlyView.
Single‐cell DNA methylation (scDNAme) profiling maps epimutational clonal evolution, revealing mechanisms of malignancy and therapeutic resistance across diverse cancer types. By providing a high‐resolution landscape of intratumoral heterogeneity, these technologies empower precise patient stratification, guide the development of enhanced ...
