Challenges and Opportunities in the Use of Iron Photosensitizers for Dye‐Sensitized Solar Cells and Photoelectrosynthetic Cells Applications

EcoEnergy, EarlyView.
This review gathers examples of iron‐based photosensitizers that have been successfully immobilized on metal oxide surfaces for dye‐sensitized solar cells and potential dye‐sensitized photoelectrosynthesic cells applications. A critical comparison of Fe‐based photosensitizers is made based on their photophysical properties, electrochemistry, and ...

Dynamic riskscapes for prey: disentangling the impact of human and cougar presence on deer behavior using GPS smartphone locations

Ecography, EarlyView.
Prey species adjust their behavior along human‐use gradients by balancing risks from predators and humans. During hunting seasons, prey often exhibit strong antipredator responses to humans but may develop tolerance in suburban areas to exploit human‐mediated resources.

CLIP-Optimized Multimodal Image Enhancement via ISP-CNN Fusion for Coal Mine IoVT under Uneven Illumination [PDF]

arXiv
Clear monitoring images are crucial for the safe operation of coal mine Internet of Video Things (IoVT) systems. However, low illumination and uneven brightness in underground environments significantly degrade image quality, posing challenges for enhancement methods that often rely on difficult-to-obtain paired reference images. Additionally, there is

Cash holding dynamics and competition intensity: Evidence from UK firms

Managerial and Decision Economics, Volume 44, Issue 1, Page 641-662, January 2023., 2023
Abstract Using a quasi‐natural experiment and various measures of competition intensity, we examine whether an increase in product market competition is a key driver of firm cash holdings. We find that firms increase cash holdings when competition is intense.
