Chromagar is a medium that is used in culture-based colonization studies of Staphylococcus aureus. We have found that S. aureus negative colonies often fit the color recommendations for S. aureus identification and can cause overestimation of colonization rates. Confirmation of suspect colonies is important to minimize false negative/positive results.

Schizophrenia (SZ) is a chronic neuropsychiatric disorder characterized by disturbances in cognitive, perceptual, social, emotional, and behavioral functions. The conventional SZ diagnosis relies on subjective assessments of individuals by psychiatrists, which can result in bias, prolonged procedures, and potentially false diagnoses. This emphasizes the crucial need for early detection and treatment of SZ to provide timely support and minimize long-term impacts.

The contaminated transformer oil is one of the major causes of failure in the power system. Detection and continuous monitoring of moisture content in transformer oil is required for the smooth operation of a system. In this paper, a Fractal-based Sinusoidal-shaped Capacitive Sensor (FSCS) is proposed to increase the contact area between capacitor plates and dielectric medium by 17.

Objective: Assessing myocardial perfusion in acute myocardial infarction is important for guiding clinicians in choosing appropriate treatment strategies. Echocardiography can be used due to its direct feedback and bedside nature, but it currently faces image quality issues and an inability to differentiate coronary macro- from micro-circulation. We previously developed an imaging scheme using high frame-rate contrast-enhanced ultrasound (HFR CEUS) with higher order singular value decomposition (HOSVD) that provides dynamic perfusion and vascular flow visualization.

Purpose: Modeling passively collected smartphone sensor data (called digital phenotyping) has the potential to detect distress among family caregivers and patients with advanced cancer and could lead to novel clinical models of cancer care. The purpose of this study was to assess the feasibility and acceptability of collecting passive smartphone data from family caregivers and their care recipients with advanced cancer over 24 weeks.

Methods: This was an observational feasibility study.

Combat sports encompass a wide range of disciplines, each associated with distinct injury patterns and mechanisms. From karate to wrestling, athletes face varying degrees of injury risks, with common clinical presentations including head injuries, strains, sprains, fractures, and concussions. These injuries often result from dynamic movements, physical contact, and high-impact collisions inherent to combat sports.
