Critical Dynamics of Superconductors in the Charged Regime [PDF]
Physical Review Letters, 2004 We investigate the finite temperature critical dynamics of three-dimensional superconductors in the charged regime, described by a transverse gauge field coupling to the superconducting order parameter. Assuming relaxational dynamics for both the order parameter and the gauge fields, within a dynamical renormalization group scheme, we find a new ...

A Radiation-Hardened Low-Power SRAM with Enhanced Write Capability for Space Applications
Applied SciencesWith continued scaling of CMOS technology, the critical charge required for state retention in SRAM cells has decreased, leading to increased vulnerability to radiation-induced soft errors such as single-event upsets (SEUs) and single-event multi-node ...

Holographic entanglement entropy of a 1 + 1 dimensional p-wave superconductor
Journal of High Energy Physics, 2017 We examine the behavior of entanglement entropy S A EE of a subsystem A in a fully backreacted holographic model of a 1 + 1 dimensional p wave superconductor across the phase transition. For a given temperature, the system goes to a superconducting phase

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

The Effect of Dust Particles on Ion Acoustic Solitary Waves in a Dusty Plasma [PDF]
Journal of Astronomy and Space Sciences, 2004 In this paper we have examined the effect of dust charge density on nonlinear ion acoustic solitary wave which propagates obliquely with respect to the external magnetic field in a dusty plasma.

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.

Preventing Space Charge Accumulation by Incorporating Electrets
Advanced Materials Interfaces, 2023 Space charge accumulates near electrodes in insulating materials under high voltage direct current. Electric stress created by charge accumulation distorts electric field, reduces the remaining useful life of insulating materials, and decreases partial ...
