Globally scalable glacier mapping by deep learning matches expert delineation accuracy.

Accurate global glacier mapping is critical for understanding climate change impacts. Despite its importance, automated glacier mapping at a global scale remains largely unexplored. Here we address this gap and propose Glacier-VisionTransformer-U-Net (GlaViTU), a convolutional-transformer deep learning model, and five strategies for multitemporal global-scale glacier mapping using open satellite imagery.

[Markers of cardiovascular system damage as additional criteria for the diagnosis of sarcopenia.].

Sarcopenia is a pathological condition characterized by muscle failure associated with age, in which muscle mass and strength decrease and, as a result, functional status and quality of life decrease. The article discusses and presents the stiffness of the arterial wall and the vascular wall reflection index as markers of damage to the cardiovascular system in elderly and senile women with arterial hypertension; the influence of markers of damage to the cardiovascular system in the development of sarcopenia is considered; an algorithm for the diagnosis of sarcopenia for clinical practice is presented.

Whole-Body Human Ultrasound Tomography.

Ultrasonography is a vital component of modern clinical care, with handheld probes routinely used for a variety of applications. However, handheld ultrasound imaging is limited by factors such as the partial-body field of view, operator dependency, contact-induced distortion, and lack of transmission contrast. Here, we demonstrate a new system enabling whole-body ultrasound tomography of humans in reflection and transmission modes.

Quantification of Cervical Elasticity During Pregnancy Based on Transvaginal Ultrasound Imaging and Stress Measurement.

Unlabelled: Strain elastography and shear wave elastography are commonly used to quantify cervical elasticity. However, the absence of stress information in strain elastography causes difficulty in inter-session elasticity comparison, and the robustness of shear wave elastography is compromised by cervical tissue's high inhomogeneity.

Objective: To overcome these limitations, we develop a quantitative cervical elastography system by adding a stress sensor to a clinically used transvaginal ultrasound imaging system.

Photoacoustic imaging of the dynamics of a dye-labeled IgG4 monoclonal antibody in subcutaneous tissue reveals a transient decrease in murine blood oxygenation under anesthesia.

Significance: Over 100 monoclonal antibodies have been approved by the U.S. Food and Drug Administration (FDA) for clinical use; however, a paucity of knowledge exists regarding the injection site behavior of these formulated therapeutics, particularly the effect of antibody, formulation, and tissue at the injection site.
