Helioseismic inference of the solar radiative opacity.

The Sun is the most studied of all stars, and thus constitutes a benchmark for stellar models. However, our vision of the Sun is still incomplete, as illustrated by the current debate on its chemical composition. The problem reaches far beyond chemical abundances and is intimately linked to microscopic and macroscopic physical ingredients of solar models such as radiative opacity, for which experimental results have been recently measured that still await theoretical explanations.

Sanctuary for vulnerable Arctic species at the Borealis Mud Volcano.

Borealis is a recently discovered submerged mud volcano in the Polar North Atlantic, differing from the numerous methane seepages previously identified in the region. Here we show in situ observations from a remotely operated vehicle (ROV), capturing the release of warm (11.5 °C) Neogene sediments and methane-rich fluids from a gryphon at Borealis.

Efficacy and safety of an algorithm using C-reactive protein to guide antibiotic therapy applied through a digital clinical decision support system: a study protocol for a randomised controlled clinical trial.

Guidelines International Network: Principles for Use of Artificial Intelligence in the Health Guideline Enterprise.

Description: Artificial intelligence (AI) has been defined by the High-Level Expert Group on AI of the European Commission as "systems that display intelligent behaviour by analysing their environment and taking actions-with some degree of autonomy-to achieve specific goals." Artificial intelligence has the potential to support guideline planning, development and adaptation, reporting, implementation, impact evaluation, certification, and appraisal of recommendations, which we will refer to as "guideline enterprise." Considering this potential, as well as the lack of guidance for the use of AI in guidelines, the Guidelines International Network (GIN) proposes a set of principles for the development and use of AI tools or processes to support the health guideline enterprise.

Correlation between body composition variables, plantar pressure and pain level.

From a current perspective, it is understood that body posture is influenced by individual asymmetries, cultural context, habitual body patterns, etiological factors and psychosocial factors allocated to the individual. Clarifying the musculoskeletal cause that originated the postural alteration is considered the clinical challenge in the treatment of pain or discomfort. Recent studies have shown the influence of changes in body weight on the distribution of plantar pressure and foot pain, emphasizing the importance of understanding these relationships.
