Gravitational Waveforms for Precessing, Quasi-circular Binaries via Multiple Scale Analysis and Uniform Asymptotics: The Near Spin Alignment Case

, 2013
We calculate analytical gravitational waveforms in the time- and frequency-domain for precessing quasi-circular binaries with spins of arbitrary magnitude, but nearly aligned with the orbital angular momentum.

Microplastics from Wearable Bioelectronic Devices: Sources, Risks, and Sustainable Solutions

Advanced Functional Materials, EarlyView.
Bioelectronic devices (e.g., e‐skins) heavily rely on polymers that at the end of their life cycle will generate microplastics. For research, a holistic approach to viewing the full impact of such devices cannot be overlooked. The potential for devices as sources for microplastics is raised, with mitigation strategies surrounding polysaccharide and ...

Domain‐Wall‐Free Sliding Ferroelectricity in Fully Commensurate 3R Transition Metal Dichalcogenide Bilayers

Advanced Functional Materials, EarlyView.
It is reported that the ferroelectric switching behavior of rhombohedral (3R) phase transition metal dichalcogenide (TMD) bilayers strongly depends on their domain structures. Single‐domain TMDs (SD‐TMDs) with domain‐wall‐free structures exhibit robust and stable polarization switching, whereas poly‐domain TMDs (PD‐TMDs) with randomly distributed ...

Waveform

International Journal of Creative Media Research
The film Waveform is an output from a project of the same name that has been ongoing since 2017, and which centres on the use of drones as tools for generating poetry. Initially, a drone captures aerial images of incoming ocean waves. These images are then analysed by a machine vision system that traces the boundary between wave and shore.

A Van der Waals Optoelectronic Synapse with Tunable Positive and Negative Post‐Synaptic Current for Highly Accurate Spiking Neural Networks

Advanced Functional Materials, EarlyView.
A van der Waals optoelectronic synaptic device based on a ReS2/WSe2 heterostructure and oxygen‐treated h‐BN is presented, which enables both positive and negative PSCs through photocarrier polarity reversal. Bidirectional plasticity arises from gate‐tunable band bending and charge trapping‐induced quasi‐doping.

Leakage Current Waveforms and Arcing Characteristics of Epoxy Resin for Outdoor Insulators under Clean and Salt Fogs [PDF]

ITB Journal of Engineering Science, 2008
Ceramic outdoor insulators have been used in high voltage transmission lines since long time ago. Due to superiority in their resistance to pollution, recently, polymeric outdoor insulators are widely used.
