Frequency calibration of voltage transformers by digital capacitance bridge

, 2015
In modern power systems, several conducted disturbances and power quality phenomena are commonly experienced also at medium voltage level. Therefore, voltage and current transducers, which scale voltage/current waveforms down to levels compatible with ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS 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.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

NONLINEAR OVERVOLTAGE LIMITER APPLICATION FOR INTERNAL OVER-VOLTAGE PROTECTION IN AVERAGE VOLTAGE NETWORKS

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2005
Review of internal over-voltages in distribution networks 6…10 kV and means of their limitation has been carried out. One of the most efficient remedy for reduction of over-voltage at arcing ground is resistive neutral grounding.

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

FEBS 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.

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

FEBS 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 ...
