Bacterial responses to decreasing osmolality involve mechanosensitive channels. The crystal structure has been determined of the small conductance mechanosensitive channel (MscS) from Escherichia coli, providing new insights into mechanical and voltage sensing by this and other channel proteins.

Abstract Monolithic thin-wall components of 2219 Al–Cu alloy are widely used in aerospace and military fields, usually treated with solution quenching to improve their comprehensive performance. However, a high magnitude residual stress is introduced into the during process, which unfavorable subsequent manufacturing process service Therefore, relief essential enhance performance components. A ...

This thesis investigates packaging effects on precision bandgap voltage references used in LTC switching regulators. Packaging stress causes a mean offset and room temperature distribution widening of the bandgap reference output voltage, as well as inconsistent temperature characteristics. Bandgap references with and without a proprietary stress-relief mechanism were compared to determine the ...
