Rotor Slot Permeance Harmonics under Distorted Air-Gap Flux Waveform for Cage Induction Motors [PDF]

open access: yes, 1991
The air-gap flux waveform for a cage induction machine is not sinusoidal in shape and contains various harmonics, including the phase-belt harmonics, slot magnetomotive force (mmf) harmonics, slot permeance harmonics, and saturation harmonics.

Flexible 3D Kirigami Probes for In Vitro and In Vivo Neural Applications

open access: yesAdvanced Materials, EarlyView.
A customizable and scalable approach to fabricate flexible 3D kirigami microelectrode arrays (MEAs) featuring up to 128 shanks, including surface and penetrating electrodes designed to interact with the 3D space of neural tissue, is presented. The 3D kirigami MEAs are successfully deployed in several neural applications, both in vitro and in vivo, and ...

Waveform-Domain Complementary Signal Sets for Interrupted Sampling Repeater Jamming Suppression [PDF]

open access: yesarXiv
The interrupted-sampling repeater jamming (ISRJ) is coherent and has the characteristic of suppression and deception to degrade the radar detection capabilities. The study focuses on anti-ISRJ techniques in the waveform domain, primarily capitalizing on waveform design and and anti-jamming signal processing methods in the waveform domain.

Intrinsically‐Stretchable and Patternable Quantum Dot Color Conversion Layers for Stretchable Displays in Robotic Skin and Wearable Electronics

open access: yesAdvanced Materials, EarlyView.
Intrinsically‐stretchable, heavy‐metal‐free quantum dot color conversion layers are produced via a versatile crosslinking strategy. The color conversion layers exhibit minimal backlight leakage under mechanical strain, support high‐resolution patterning, and integrate seamlessly with micro‐light‐emitting diodes. Their incorporation in haptic‐responsive

Triphasic waveforms are superior to biphasic waveforms for transthoracic defibrillation

open access: yesJournal of the American College of Cardiology, 2003
Our objective was to evaluate the efficacy of triphasic waveforms for transthoracic defibrillation in a swine model.Triphasic shocks have been found to cause less post-shock dysfunction than biphasic shocks in chick embryo studies.After 30 s of electrically induced ventricular fibrillation (VF), each pig in part I (n = 32) received truncated ...
