Active vibration isolation of electronic components by piezocomposite clamped–clamped beam [PDF]
Mechanical Systems and Signal Processing, 2011 The sensitive electronic components used in military and aerospace applications endure some intense vibrations. These vibrations have some disturbing effects on the stability and on the service life of these devices. So, protecting these elements becomes a major economic and strategic stake. Vibration isolation can be applied to different levels of the

The Escherichia coli Clamp Loader Can Actively Pry Open the β-Sliding Clamp [PDF]
Journal of Biological Chemistry, 2011 Clamp loaders load ring-shaped sliding clamps onto DNA. Once loaded onto DNA, sliding clamps bind to DNA polymerases to increase the processivity of DNA synthesis. To load clamps onto DNA, an open clamp loader-clamp complex must form. An unresolved question is whether clamp loaders capture clamps that have transiently opened or whether clamp loaders ...

High-Efficiency Design and Control of Zeta Inverter for Single-Phase Grid-Connected Applications
Energies, 2019 The conventional zeta inverter has been used for single-phase grid-connected applications. However, it has high switching losses to operate at high switching frequency in the continuous conduction mode (CCM). To address this drawback, this paper suggests

Frontiers in Physiology, 2023 Human-induced stem cell-derived cardiomyocytes (hiPSC-CMs) are a valuable tool for studying development, pharmacology, and (inherited) arrhythmias. Unfortunately, hiPSC-CMs are depolarized and spontaneously active, even the working cardiomyocyte subtypes

Signal transduction: Clamping down on Src activity [PDF]
Current Biology, 1997 Recent high-resolution structures of members of the Src family of protein-tyrosine kinases illustrate how a series of cooperative intramolecular interactions represses the catalytic activity of these kinases, but allows for their rapid activation by a variety of regulatory inputs.
