Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies
Advanced Functional Materials, EarlyView.The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

ANOMALOUS CORONARY ARTERIES OF AORTIC ORIGIN
International Journal of Clinical Practice, 2000 SUMMARYAnomalous coronary arteries cause only uncharacteristic symptoms and are therefore often an incidental finding during conventional coronary angiography, with an incidence of 0.3‐0.8%. The commonest anomaly is an aberrant origin of the main left or right coronary artery from the wrong sinus of Valsalva. Rarely there is a fistula draining into one

MDCT coronary angiography for diagnosis of anomalous origin right coronary artery: a case report
, 2007 This is a case report of anomalous origin of the right coronary artery, which arises from the left sinus of Valsalva depicted with multi-detector row tomography (MDCT) coronary angiography performed in emergency.

, 2021 Congenital anomalous origin of the coronary arteries is a rare but well-described cause of myocardial ischemia and sudden cardiac death. Anomalous origin of the right coronary artery from the ascending aorta is an extraordinarily rare occurrence.

Advanced Functional Materials, EarlyView.A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.

Indian Heart Journal, 2015 Anomalous origin of right coronary artery (RCA) from left sinus is a rare clinical entity. Percutaneous coronary intervention of such an anomalous RCA, which is chronically occluded, is difficult and is rarely described.

Rerouting anomalous coronary artery origin in aortopulmonary window in newborn
, 2021 Coronary artery anomalies may accompany the aortopulmonary window and, if not noticed, may cause catastrophic consequences. The repair of the aortopulmonary window is quite straightforward; however, establishing a normal coronary pattern may challenge ...

Advanced Functional Materials, EarlyView.This Perspective highlights atom probe tomography as a powerful tool for understanding the atomic‐scale defect chemistry in HfO2‐based ferroelectrics. 3D mapping of dopants, point defects, and interface chemistry can provide new insight into defect‐driven mechanisms underpinning the ferroelectricity in the system and guide the design of more reliable ...
