Kidney stone is a common urological disease in dogs and can lead to serious complications such as pyelonephritis and kidney failure. However, manual diagnosis involves a lot of burdens on radiologists and may cause human errors due to fatigue. Automated methods using deep learning models have been explored to overcome this limitation.

Decoding the semantic categories of complex sceneries is fundamental to numerous artificial intelligence (AI) infrastructures. This work presents an advanced selection of multi-channel perceptual visual features for recognizing scenic images with elaborate spatial structures, focusing on developing a deep hierarchical model dedicated to learning human gaze behavior. Utilizing the BING objectness measure, we efficiently localize objects or their details across varying scales within scenes.

Objective: Pediatric traumatic brain injury (TBI) represents a significant public health concern and source of resource utilization. The aim of this study was to establish the ability of the previously published pediatric Brain Injury Guidelines (pBIG) to identify patients with traumatic intracranial hemorrhage (ICH) who might not require routine repeat neuroimaging, neurosurgical consultation, or hospital admission in a large level I and level II trauma cohort.
Methods: Pediatric patients who presented with traumatic ICH between 2018 and 2022 at the included institutions were retrospectively reviewed and sorted into pBIG categories using clinical and radiographic criteria.

A fundamental topological principle is that the container always shapes the content. In neuroscience, this translates into how the brain anatomy shapes brain dynamics. From neuroanatomy, the topology of the mammalian brain can be approximated by local connectivity, accurately described by an exponential distance rule (EDR).

Parkinson's Disease (PD) is a neurodegenerative disorder that is often accompanied by slowness of movement (bradykinesia) or gradual reduction in the frequency and amplitude of repetitive movement (hypokinesia). There is currently no cure for PD, but early detection and treatment can slow down its progression and lead to better treatment outcomes. Vision-based approaches have been proposed for the early detection of PD using gait.
