Sen Transformer Differential Protection Scheme Based on Magnetic Circuit Coupling

open access: yesZhongguo dianli
As a power flow control device, Sen transformer changes the amplitude and phase of voltage and current at both ends of the access line through gear adjustment to achieve power flow regulation.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Flexible protection architectures using distributed optical sensors

open access: yes, 2012
In this paper we describe recent developments in flexible protection schemes that make use of passive fibre Bragg grating (FBG) based transducers for the distributed measurement of voltage and current.

Review of methodologies used for detection of magnetising inrush and fault conditions in power transformer

open access: yesIET Energy Systems Integration, 2021
Reliable and dedicated protection of the transformer is the main requirement in the power system due to the supervision of a highly expensive equipment transformer. Non‐linear characteristics of the transformer give mysterious behaviour for the period of

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Discussion of Auxiliary Power Source Open-Phase Protection in Nuclear Power Plant

open access: yes南方能源建设
[Objective] The auxiliary power source in nuclear power plant operates at no-load normally, the protection cannot alarm when it occurs single phase open, but this open-phase condition will threaten the nuclear safety seriously, it should assemble special

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.
