Dielectric Elastomer Actuators as Safe and Effective Tools for Mechanostimulation of Human Cells

Advanced Intelligent Systems, EarlyView.
Replicating physiological forces is crucial for realistic cell models. Dielectric elastomer actuators (DEAs) offer a soft alternative, though their high voltages raised toxicity concerns. We demonstrate that DEA stimulation causes no cell damage, cell death or cell‐cycle disruption, while activating mechanosensitive responses.

A Large Outburst, Coma Asymmetries, and the Color of Comet 243P/NEAT

The Planetary Science Journal
Water ice is a fundamental building material of comets and other bodies in the outer solar system. Yet the properties of cometary water ice are challenging to study, due to its volatility and the typical distances at which comets are observed.

A neck-line structure in the dust tail of Comet C/2004 F4 (Bradfield) [PDF]

Astronomy & Astrophysics, 2005
Three CCD images of Comet C/2004 F4 (Bradfield), taken on three different dates close to the time of the Earth crossing through the plane of the comet orbit (2004 May 2.9280 UT), show a ray-shaped structure (RSS) in the dust tail, accompanied by a short, sunward spike (SWS).

Dose‐Related Gastric Toxicity of Diethyl Phthalate in Female Wistar Rats

Journal of Applied Toxicology, EarlyView.
ABSTRACT Diethyl phthalate (DEP) is commonly used in cosmetics, personal care products, and pharmaceutical formulations as a low‐molecular‐weight phthalate. Despite its widespread use, information on its effects on the gastric mucosa remains limited. This study examined the dose‐related effects of DEP on inflammation, oxidative stress, gastric mucosal ...

Tail wagging cats: Veterinary implications of AI‐generated video

Veterinary Record, EarlyView.
Abstract Background Generative artificial intelligence (genAI) has the capacity to create realistic and convincing animal videos; however, it must simplify and reduce behavioural variation to do so, possibly leading to misinformation. Methods We categorised 29 videos in the press release for a specific video genAI engine. Twelve featured animals.

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

Computer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

Wide-field polarization imaging and numerical modeling of the coma and tail of comet C/2023 A3 (Tsuchinshan-ATLAS)

Astronomy & Astrophysics
Context. Imaging polarimetry enables the spatially resolved investigation of cometary dust properties across different morphological structures. While cometary comae have been studied thoroughly in the pertinent literature, cometary tails have remained ...

A Look at Eight Outbursts of Comet 7P/Pons–Winnecke

The Planetary Science Journal
Cometary outbursts may be used as a means to infer the physical processes occurring on cometary nuclei. To that end, we studied eight outbursts of comet 7P/Pons–Winnecke identified between 2021 June 3 and August 31. The data analyzed consisted of optical
