Influence of soil resistivity on stray current in power supply system of urban rail transit

open access: yesJournal of Measurement Science and Instrumentation, 2022
In order to explore the influence of soil resistivity on stray current in power supply system of urban rail transit, we establish an equivalent circuit model of the rail-to-ground structure based on resistance network method first.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Characteristics of Stray Current Distribution in the Power Supply System of Subway Tunnels with a Hollow Circular Section Structure

open access: yesEnergies
The DC traction power system adopts the track as the return rail. When the track-to-earth insulation in the subway tunnel deteriorates, stray currents will cause electrochemical corrosion to tunnel steel structures and seriously affect the service life ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Novel Bearing Current Suppression Approach in Doubly-Fed Induction Generators

open access: yesIEEE Access, 2019
Doubly-fed induction generators (DFIGs) are widely used in the wind power generation systems. However, due to the use of the power electronic devices, such as insulated gate bipolar transistor (IGBT), it is inevitable to generate a non-zero common mode ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
