Indoor-Atmospheric Radon-Related Radioactivity Affected by a Change of Ventilation Strategy [PDF]
arXiv, 2006 The present author has kept observation for concentrations of atmospheric radon, radon progeny and thoron progeny for several years at the campus of Fukushima Medical University. Accidentally, in the midst of an observation term, i.e., February 2005, the facility management group of the university changed a strategy for the manner of ventilation ...

Assessment of Pollutant Spread from a Building Basement with three Ventilation Systems [PDF]
EuroAcademy on Ventilation and Indoor Climate - CLIMACADEMY Course
7: Experimental Assessment of Indoor Environment Parameters, Pamporovo :
Bulgaria (2009), 2010 Ventilation aims at providing a sufficient air renewal for ensuring a good indoor air quality (IAQ), yet building energy policies are leading to adapting various ventilation strategies minimising energy losses through air renewal. A recent IAQ evaluation campaign in French dwellings shows important pollution of living spaces by VOCs such as ...

Improving the Photochemical Skeletal Enlargement of Pyridines to 1,2‐Diazepines with Isocyanates
Advanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.Abstract In this work, we extend the one‐pot protocol to synthesize 1,2‐diazepines from commercially available and cheap starting materials. Capitalizing on isocyanate derivatives as activating agents, the photochemical skeletal enlargement occurs, while preserving key functional groups embedded in more than 30 substrates.

Methodology for Interpretable Reinforcement Learning for Optimizing Mechanical Ventilation [PDF]
arXivMechanical ventilation is a critical life support intervention that delivers controlled air and oxygen to a patient's lungs, assisting or replacing spontaneous breathing. While several data-driven approaches have been proposed to optimize ventilator control strategies, they often lack interpretability and alignment with domain knowledge, hindering ...

A Reinforcement Learning Approach to Weaning of Mechanical Ventilation in Intensive Care Units [PDF]
arXiv, 2017 The management of invasive mechanical ventilation, and the regulation of sedation and analgesia during ventilation, constitutes a major part of the care of patients admitted to intensive care units. Both prolonged dependence on mechanical ventilation and premature extubation are associated with increased risk of complications and higher hospital costs,
