Excitation control: balancing PSD-95 function at the synapse
Frontiers in Molecular Neuroscience, 2008 Excitability of individual neurons dictates the overall excitation in specifi c brain circuits. This process is thought to be regulated by molecules that regulate synapse number, morphology and strength.

Simulation of a Power Transformer Differential Protective Relay [PDF]
Engineering and Technology Journal, 2009 The aim of this work is to simulate a differential relay, which ensures security for external fault, inrush, and overexcitation conditions and provides dependability for internal faults, to protect a single phase power transformer.

FEBS Letters, EarlyView.B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Evolutionary interplay between viruses and R‐loops
FEBS Letters, EarlyView.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Seeded excitation avalanches in off-resonantly driven Rydberg gases
, 2016 We report an experimental investigation of the facilitated excitation dynamics in off-resonantly driven Rydberg gases by separating the initial off-resonant excitation phase from the facilitation phase, in which successive facilitation events lead to ...
