Energy Science &Engineering, EarlyView.A real‐time power quality disturbance generator is developed using virtual instrumentation based on LabVIEW and NI MyDAQ. The system generates IEEE‐standard PQ events with controllable noise and harmonics. Measurement uncertainty analysis confirms its reliability for realistic testing of Power Quality Disturbance detection and classification algorithms.

International Journal of Gynecology &Obstetrics, EarlyView.Abstract Objective While cardiometabolic comorbidities have been well established in adults with polycystic ovary syndrome (PCOS), it remains unclear whether the early signs of cardiovascular morbidity emerge during adolescence. This study aimed to investigate whether metabolic and cardiovascular alterations begin in adolescents with PCOS.

A −107.8 dB THD+N Low-EMI Multi-Level Class-D Audio Amplifier
2020 IEEE Symposium on VLSI Circuits, 2020 This paper describes a class-D audio amplifier with a multilevel output stage that reduces both EMI and idle power. High loop gain, and thus high linearity, are enabled by a relatively high (4.2 MHz) switching frequency, which relaxes the requirements on its output LC filter. Fabricated in a 180nm BCD technology, it can drive 14 W into an 8-Ω load with

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose Dynamic tibiofemoral movements following anterior cruciate ligament reconstruction (ACLR) with quadriceps tendon (QT) autografts have not yet been compared to other autografts. We aimed to compare dynamic anterior tibial translation (ATTd) and internal tibial rotation (ITRd) during jump‐landing and walking among patients with QT, bone ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.Mediterranean tropical‐like cyclones show a clear seasonality, with September cyclones exhibiting the deepest convection and Ianos representing the most extreme case. While one or more dry intrusions are typically detected during the cyclone life cycle, Ianos instead features two much weaker descending airflows.

A 1-nS 1-V Sub-1-µW Linear CMOS OTA with Rail-to-Rail Input for Hz-Band Sensory Interfaces
Sensors, 2020 The paper presents an operational transconductance amplifier (OTA) with low transconductance (0.62–6.28 nS) and low power consumption (28–270 nW) for the low-frequency analog front-ends in biomedical sensor interfaces.

Tuning the Length of Filomicelles Prepared Via Templated Polymerization‐Induced Self‐Assembly
Small, EarlyView.High‐aspect‐ratio polymeric micelles are attractive yet notoriously difficult to control in length. We reveal a counterintuitive and powerful solution: in supramolecularly templated PISA, adding non‐sticker polymer unexpectedly elongates the micelles, while post‐assembly sonication enables precise shortening with reduced dispersity.
