Survey and Assessment of the Economic Loss Caused by Supply Voltage Sags and Interruptions in Typical Industrial Plants

Kongzhi Yu Xinxi Jishu, 2012
Power quality is becoming more and more important for modern manufacture and process control industries, any voltage sags and momentary interruptions on the power supply voltage lasting more than a few cycles will bring massive economic loss.

Healing Following Endoscopic Reconstruction of the Anterior Skull Base in Patients With Sinonasal Malignancies

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Healing dynamics after anterior skull base (ASB) reconstruction following transnasal endoscopic surgery (TES) for sinonasal malignancies remain poorly characterized. This study aimed to describe the postoperative healing process, quantify time to healing, identify factors influencing healing, and assess radiologic evolution over ...

A Comprehensive In Vitro Approach for Assessing the Physiological Degradation of Medical Implants: The Silkothane Arteriovenous Graft Case Study

Advanced NanoBiomed Research, EarlyView.
Evaluating the degradation of absorbable medical devices in vitro demands physiologically relevant conditions. This study presents a comprehensive framework applied to a three‐layered silk fibroin/polyurethane arteriovenous graft, employing human enzymes at physiological concentrations over 6 months. Multiparametric analyses of both graft structure and

Diffusion‐Governed Growth Mechanisms of Epitaxial GaAs Islands on CMOS‐Compatible Si(001) Nanotip Arrays

Advanced Physics Research, EarlyView.
The mechanism and kinetics of selective GaAs growth on Si nanotip wafers via nanoheteroepitaxy were investigated as a function of pitch (center‐to‐center nanotip spacing). The pitch dependence reveals distinct surface‐diffusion‐controlled regimes, demonstrating that lateral Ga adatom transport on the SiO2 mask governs material redistribution and ...

Marginal Convergence Repair Technique for Partial Articular‐Sided Rotator Cuff Tears

Arthroscopy Techniques, EarlyView.
Abstract Partial rotator cuff tears present a common clinical challenge, and optimal management remains debated. This technical note describes an arthroscopic margin convergence repair technique performed without the use of suture anchors for patients with partial‐thickness rotator cuff tears.
