Estimation of Railway Line Impedance at Low Frequency Using Onboard Measurements Only
EnergiesEstimating line impedance is relevant in transmission and distribution networks, in particular for planning and control. The large number of deployed PMUs has fostered the use of passive indirect methods based on network model identification. Electrified

Electronics Letters, 1969 The method described measures the magnitude of an unknown impedance by a single unambiguous adjustment. The circuit presented is similar to the Starr and Grutzmacher bridges, but does not require repeated adjustment. The phase of the impedance may be found if desired.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Visualising the lubrication condition in hydrodynamic journal bearings using impedance measurement
Frontiers in Mechanical EngineeringIntroductionThe demand to increase reliability and reduce maintenance costs drives the search for new condition monitoring solutions of machines. Bearings are of special interest in this matter as they are main contributors to machine downtime. Therefore,

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

International Journal of Electrochemical Science, 2017 In this paper, nano-hybrid composites of water-soluble, conducting polymer poly (diphenylamine sulfonic acid) (PSDA) with nano-Al2O3 and (3-mercaptopropyl) trimethoxysilane (MPTMS) have been prepared to construct the interdigitated impedimetric type of ...

Molecular Oncology, EarlyView.ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.
