Lacking data? No worries! How synthetic images can alleviate image scarcity in wildlife surveys: A case study with muskox (Ovibos moschatus)

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study investigates the integration of synthetic imagery, created with diffusion‐based models, to supplement limited training data and improve muskox (Ovibos moschatus) detection in zero‐shot (ZS) and few‐shot (FS) settings. ZS models detected more than 80% of muskoxen in real images, confirming the potential of synthetic data as a substitute for ...

Advanced Fade Mitigation Techniques for Q/V Band SATCOM Systems

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Adaptive fade mitigation techniques, such as smart gateway diversity (SGD), are essential in addressing atmospheric fading affecting the operation of high throughput and very high throughput satellite systems at Ka‐band and beyond. Specifically, the Q/V‐band, offering up to 5 GHz of available spectrum, is very attractive for future high data ...

Are physiological oscillations physiological?

open access: yesThe Journal of Physiology, EarlyView., 2023
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Research advances in the applications of mitochondria‐targeted cyanine dyes in imaging

open access: yesVIEW, EarlyView.
Near‐infrared (NIR) fluorescence imaging, a novel non‐invasive diagnostic tool, plays a crucial role in the imaging and monitoring of solid tumors. At its core are NIR fluorescent dyes, which are widely utilized due to their ability to minimize tissue autofluorescence interference, thereby significantly enhancing the signal‐to‐noise ratio (SNR) and ...
