Reversibility, Water-Mediated Switching, and Directed Cell Dynamics [PDF]

open access: yesarXiv, 2008
Reversible switching of the complex network dynamics of proteins is mimicked in selected network glasses and compacted small carbohydrate molecules. Protein transitions occur on long time scales ~ us -ms, evocative of the exponentially large viscosities found in glass-forming supercooled liquids just above the glass transition; in searching for ...

Mutagenicity of Bulk, Aqueous and Organic Partitions of Air Particulate Matter in Differentially Ventilated Wards in a Public Urban Hospital [PDF]

open access: yesNature Environment and Pollution Technology, 2019
The hospital environment requires indoor air quality conducive to the recovery of patients with poor health. Low indoor air quality is associated with an increased incidence of respiratory tract diseases and the development of cancer.

Health Hazard Manual For Cutting Oils, Coolants, and Metalworking Fluids [PDF]

open access: yes, 1991
[Excerpt] The metalworker can be exposed to cutting oils during application by two basic routes of entry: skin contact and inhalation. The higher risk jobs tend to be those with high cutting speeds, heavy oil flow, and continuous contact, which may ...

Process of Infection with Bacteriophage φX174 XXXIII. Templates for the Synthesis of Single-Stranded Deoxyribonucleic Acid [PDF]

open access: yes, 1970
The origin of the templates for the synthesis of {varphi}X174 progeny single-stranded deoxyribonucleic acid was studied by means of the mutagenic activity associated with the decay of incorporated 3H-labeled 5-cytosine.

Genetic toxicity studies of organic chemicals found as contaminants in spacecraft cabin atmospheres [PDF]

open access: yes
Astronauts can be exposed during spaceflight to organic chemical contaminants in the spacecraft cabin atmosphere. Toxic exposures may cause lesions in the cellular DNA which are subsequently expressed as sister-chromatid exchanges (SCE).

Global Concept Explanations for Graphs by Contrastive Learning [PDF]

open access: yesarXiv
Beyond improving trust and validating model fairness, xAI practices also have the potential to recover valuable scientific insights in application domains where little to no prior human intuition exists. To that end, we propose a method to extract global concept explanations from the predictions of graph neural networks to develop a deeper ...
