Investigation of a resistive anode detector for astronomical spectroscopy

, 1986
A large format two dimensional photon counting detector has been evaluated as a detector for astronomical spectroscopy. The design comprises an 320 photocathode, a tandem MCP gain stage and a circular arc terminated resisitive anode to provide pOSitional coordinates of detected events.

Benchmarking Hybrid CNN‐Transformer Versus Pure Transformer Architectures for Accelerated Hyperpolarized 129Xe MRI Reconstruction

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Hyperpolarized 129Xe MRI faces technical challenges including low signal‐to‐noise ratio and breath‐hold constraints. Current literature focuses on proprietary deep learning methods or image‐domain enhancements. Purpose To present a comprehensive evaluation of transformer and hybrid CNN‐transformer architectures integrating dual ...

Sunshine Duration in Brazil From Meteosat (1983–2020): Climatology, Variability and Long‐Term Trends

International Journal of Climatology, EarlyView.
Using nearly four decades of Meteosat satellite data (1983–2020), this study presents a country‐wide climatology of sunshine duration (SDU) in Brazil. The results reveal marked regional contrasts, dominant modes of variability, and significant long‐term trends, providing new information on the most relevant meteorological systems that influence SDU and

Weather Patterns Associated With Coastal Disasters in Santa Catarina, Southern Brazil

International Journal of Climatology, EarlyView.
The study identified weather patterns (WPs) associated with coastal disasters between 1998 and 2020 along the Santa Catarina coast, Brazil. Using atmospheric and oceanographic data combined with official disaster records, five WPs were defined, mainly associated with cyclonic and anticyclonic systems linked to extreme wave events.

A Power‐Efficient Monte Carlo Framework for Nonlinear Light–Matter Interactions: In Silico Modeling of Spontaneous and Stimulated Raman Scattering in Turbid Media

Journal of Raman Spectroscopy, EarlyView.
Power‐efficient Monte Carlo modeling of nonlinear light–matter interactions in turbid media is demonstrated using Apple Silicon–accelerated photon transport. The Metal‐base framework enables accurate simulation of spontaneous and stimulated Raman scattering, revealing detection‐dependent SRS efficiency while providing a scalable, energy‐efficient ...

From Niche to Mainstream: A Knowledge Exchange Model for Sustainable Housing Adoption

Knowledge and Process Management, EarlyView.
ABSTRACT As climate change intensifies the demand for sustainable practices, the residential housing sector remains a critical yet underutilized area for promoting energy efficiency. Although consumer awareness is increasing, sustainable and energy‐efficient (SEE) housing continues to occupy a niche market.
