Allometric scaling of heat and water exchanges in the mammals' lung [PDF]
Mammals have a high metabolism that produces heat proportionally to the power 3/4 of their mass at rest. Any excess of heat has to be dissipated in the surrounding environment to prevent overheating. Most of that dissipation occurs through the skin, but the efficiency of that mechanism decreases with the animal's mass.

A framework for dynamically training and adapting deep reinforcement learning models to different, low-compute, and continuously changing radiology deployment environments [PDF]
While Deep Reinforcement Learning has been widely researched in medical imaging, the training and deployment of these models usually require powerful GPUs. Since imaging environments evolve rapidly and can be generated by edge devices, the algorithm is required to continually learn and adapt to changing environments, and adjust to low-compute devices ...

Understanding Vasomotion of Lung Microcirculation by In Vivo Imaging
The balance of lung extravascular water depends upon the control of blood flow in the alveolar distribution vessels that feed downstream two districts placed in parallel, the corner vessels and the alveolar septal network. The occurrence of an edemagenic

Using geometric algebra to represent curvature in shell theory with applications to Starling resistors [PDF]
We present a novel application of rotors in geometric algebra to represent the change of curvature tensor, that is used in shell theory as part of the constitutive law. We introduce a new decomposition of the change of curvature tensor, which has explicit terms for changes of curvature due to initial curvature combined with strain, and changes in ...

Effect of β2-adrenergic receptor stimulation on lung fluid in stable heart failure patients [PDF]
Introduction: The purpose of this study was to determine 1) if stable heart-failure patients with reduced ejection fraction (HFrEF) have elevated extravascular lung water (EVLW) versus healthy control subjects, and 2) the effect of acute β2AR agonist ...

Capturing the shear and secondary compression wave: High frame rate ultrasound imaging in saturated foams [PDF]
We experimentally observe the shear and secondary compression wave inside soft porous water-saturated melamine foams by high frame rate ultrasound imaging. Both wave speeds are supported by the weak frame of the foam. The first and second compression waves show opposite polarity, as predicted by Biot theory. Our experiments have direct implications for

Basement membrane-rich Organoids with functional human blood vessels are permissive niches for human breast cancer metastasis [PDF]
Metastasic breast cancer is the leading cause of death by malignancy in women worldwide. Tumor metastasis is a multistep process encompassing local invasion of cancer cells at primary tumor site, intravasation into the blood vessel, survival in systemic ...

Inhaled nitric oxide does not prevent postpneumonectomy pulmonary edema in pigs [PDF]
ObjectiveIncrease in lung permeability is an inevitable consequence of pneumonectomy in relation to inflammatory injury and increased perfusion flow. We tested whether inhaled nitric oxide, a potent vasodilatator and anti-inflammatory agent, prevents ...
