Training CNN Classifiers for Semantic Segmentation using Partially Annotated Images: with Application on Human Thigh and Calf MRI [PDF]
arXiv, 2020 Objective: Medical image datasets with pixel-level labels tend to have a limited number of organ or tissue label classes annotated, even when the images have wide anatomical coverage. With supervised learning, multiple classifiers are usually needed given these partially annotated datasets.

Cuproplasia and cuproptosis, two sides of the coin
Cancer Communications, EarlyView.Abstract Copper is an essential micronutrient in the human body, mainly acting as a crucial cofactor required for a wide range of physiological processes across nearly all cell types. Recent advances revealed that tumor cells seize copper to fulfill their rapid proliferation, metastasis, immune evasion, and so on by reprogramming the copper regulatory ...

Comments on "Ballistics: a primer for the surgeon" [PDF]
Injury, 2008 Aug; 39(8): p 964-5, 2008 In response to a published assertion to the contrary, this paper briefly reviews many studies that document remote wounding effects of ballistic pressure waves including experiments in pigs and dogs that find brain injury resulting from animal models shot in the thigh and case studies in humans that document both remote brain and spinal cord injuries ...

On the origin of thigh-frequency radiation in experimental earthquakes [PDF]
, 2019 We monitor dynamic rupture propagation during laboratory stick-slip experiments performed on saw-cut Westerly granite under upper crustal conditions (10-90 MPa). Spectral analysis of high-frequency acoustic waveforms provided evidence that energy radiation is enhanced with stress conditions and rupture velocity.

HuGaDB: Human Gait Database for Activity Recognition from Wearable Inertial Sensor Networks [PDF]
arXiv, 2017 This paper presents a human gait data collection for analysis and activity recognition consisting of continues recordings of combined activities, such as walking, running, taking stairs up and down, sitting down, and so on; and the data recorded are segmented and annotated.

Differentiating Sitting and Lying Using a Thigh-Worn Accelerometer.
Medicine & Science in Sports & Exercise, 2016 UNLABELLED A triaxial accelerometer worn on the thigh can provide information on the angle of rotation of the thigh. These data may be used to estimate periods of lying versus sitting.

Association between Thigh Muscle Volume and Leg Muscle Power in Older Women
PLoS ONE, 2016 The construct of sarcopenia is still discussed with regard to best appropriate measures of muscle volume and muscle function. The aim of this post-hoc analysis of a cross-sectional experimental study was to investigate and describe the hierarchy of the ...

Effects of life history strategies and habitats on limb regeneration in plethodontid salamanders
Developmental Dynamics, EarlyView.Abstract Background Salamanders are the only tetrapods that exhibit the ability to fully regenerate limbs. The axolotl, a neotenic salamander, has become the model organism for regeneration research. Great advances have been made providing a detailed understanding of the morphological and molecular processes involved in limb regeneration.
