Shape of Testosterone
(American Chemical Society, 2021-07-29)
We have successfully characterized the structure of testosterone, one of the essential steroids, through high-resolution rotational spectroscopy. A single conformer has been detected, and a total of 404 transitions have ...
Farmland composition and farming practices explain spatio-temporal variations in red-legged partridge density in central Spain
(Elsevier, 2021-12-10)
Many farmland bird populations are declining, and their negative trends are often associated with changes in land-use or farming practices, including the use of agrochemicals. The red-legged partridge (RLP) is a Mediterranean ...

(Wiley, 2021-08-21)
Aim To describe the protocol for the pilot phase of a complex intervention, designed to address primary care nurses' role confusion in health promotion. Design A pilot clustered randomized controlled trial, with control ...
Nd3+-Doped Lanthanum Oxychloride Nanocrystals as Nanothermometers
(American Chemical Society, 2021-09-16)
The development of optical nanothermometers operating in the near-infrared (NIR) is of high relevance toward temperature measurements in biological systems. We propose herein the use of Nd3+-doped lanthanum oxychloride ...

Spatiotemporal CNN with Pyramid Bottleneck Blocks: Application to eye blinking detection
(Pergamon-Elsevier, 2022-04-18)
Eye blink detection is a challenging problem that many researchers are working on because it has the potential to solve many facial analysis tasks, such as face anti-spoofing, driver drowsiness detection, and some health ...
Pitfalls on evaluating pair exchange interactions for modelling molecule-based magnetism
(Royal Society of Chemistry, 2021-09-07)
Molecule-based magnetism is a solid-state property that results from the microscopic interaction between magnetic centres or radicals. The observed magnetic response is due to unpaired electrons whose coupling leads to a ...
