Acute pressure overload of the right ventricle. Comparison of two models of right-left shunt. Pulmonary artery to left atrium and right atrium to left atrium: experimental study

Journal of Cardiothoracic Surgery, 2011
Abtract Background In right ventricular failure (RVF), an interatrial shunt can relieve symptoms of severe pulmonary hypertension by reducing right ventricular preload and increasing systemic flow.

Unveiling a Near‐Total Rear Passivation for High Performance of Ultra‐Thin ACIGS

Advanced Science, EarlyView.
Ultra‐thin solar cells of (Ag,Cu)(In,Ga)Se2 (ACIGS) suffer from rear interface recombination, limiting their performance. To tackle it, a full coverage plasma enhanced chemically vapor‐deposited 8 nm porous SiOx passivation layer was implemented and evaluated. It is shown that a combination of the near‐complete passivation from silica and the formation

Randomized preclinical study of machine perfusion in vascularized composite allografts

BJS (British Journal of Surgery), EarlyView., 2020
This study was designed to identify the optimum machine perfusion parameters for preservation of limbs before transplantation, and determine whether this was better than cold storage. Normothermic machine perfusion at a pressure of 70 mmHg (NMP‐70) provided superior preservation to cold storage after transplantation.

A Review of Shunting Effect in Resistance Spot Welding

Przegląd Spawalnictwa - Welding Technology Review, 2016
Studies on shunting effect in resistance spot welding (RSW) have not been widely performed and limited researches were devoted to some aspects of it. Shunting effect in RSW occurs when the electrical current passes through the preceded spot welds in the case of multi-spot welding.

Supranational surveillance of antimicrobial resistance: The legacy of the last decade and proposals for the future

, 2010
Antimicrobial resistance among clinically important bacteria is widely acknowledged as a major global public health threat. A decade ago, several supranational surveillance initiatives were introduced. Few of them are still ongoing, and only one features

From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits

Advanced Science, EarlyView.
This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

Structural Changes and Transport Properties of YBa2Cu3O7 Locally Modified by a He+ Focused Ion Beam

Advanced Science, EarlyView.
The structure and the electric transport properties of YBa2Cu3O7 modified with 30 keV He+${\rm He}^{+}$ ions depend on the irradiation dose and lateral size of the irradiated area, as shown by low‐temperature resistivity measurements, diffraction with a nanofocused X‐ray beam and atomic force microscopy.
