Prehospital randomised assessment of a mechanical compression device in cardiac arrest (PaRAMeDIC) trial protocol [PDF]

, 2010
Background Survival after out-of-hospital cardiac arrest is closely linked to the quality of CPR, but in real life, resuscitation during pre-hospital care and ambulance transport is often suboptimal.

Regulation and mechanism of graphene electrode bending on negative differential resistance of 2-phenylpyridine molecular devices

Acta Physica Sinica, 2023
Combining non-equilibrium Green’s function with density functional theory, we study the electronic transport properties of the molecular devices comprised of 2-phenylpyridine and zigzag graphene nanoribbon (ZGNR) electrodes. The <i>I-V</i> characteristics and transmission coefficients under external voltage biases are analyzed, and the ...

Iso-osmotic contrast filling of an artificial urinary sphincter is a safe and effective tool for diagnosis of mechanical failure [PDF]

Investigative and Clinical Urology
Purpose: Recurrent stress incontinence (SUI) in patients with an artificial urinary sphincter (AUS) is a diagnostic challenge. History, physical exam and office cystoscopy are often inadequate for determining the cause of device related issues.

Energy harvesting from vibrations with a nonlinear oscillator [PDF]

, 2009
In this paper we present a nonlinear electromagnetic energy harvesting device that has a broadly resonant response. The nonlinearity is generated by a particular arrangement of magnets in conjunction with an iron-cored stator.
