Coordination and persistence of aggressive visual communication in Siamese fighting fish.

Outside acoustic communication, little is known about how animals coordinate social turn taking and how the brain drives engagement in these social interactions. Using Siamese fighting fish (Betta splendens), we discover dynamic visual features of an opponent and behavioral sequences that drive visually driven turn-taking aggressive behavior. Lesions of the telencephalon show that it is unnecessary for coordinating turn taking but is required for persistent participation in aggressive interactions.

A discrete choice experiment with health professions trainees to improve the urban-rural health care access disparity in Appalachia: Study protocol.

Globally, those who live in rural areas experience significant barriers to accessing health care due to a maldistribution of health care providers. Those who live in rural areas in the Appalachian region of the United States face one of the worst shortages of health care providers despite experiencing more complex health needs compared to Americans in more affluent, urban areas. Prior research has failed to identify effective solutions to narrow the provider maldistribution, despite it being a policy focus for decades.

Diabetic foot ulcer photography study: a study within a trial to assess the reliability of two-dimensional (2D) photography for the assessment of ulcer healing in patients with diabetes-related foot ulcers-protocol paper.

Background: The primary endpoint in diabetes-related foot ulcer (DFU) trials is often time to healing, defined as complete re-epithelialisation with absence of drainage, requiring clinical expert assessment as the gold standard. Central blinded photograph review for confirmation of healing is increasingly being undertaken for internal validity. The Diabetic Foot Ulcer Photography study aims to determine the agreement between blinded independent review panel members for assessing ulcer healing status in patients with DFUs.

Yes, We Can! Ensuring That our Graduating Resident's Procedural Skills Meet the Needs of Their Patients.

Objectives: There is a burgeoning discrepancy between the procedural competency of graduating diagnostic radiology residents and the needs of our patient population. The causes of this mismatch and opportunities for improvement are explored by the APDR Procedural Competency of Graduating DR Residents Task Force.

Materials And Methods: The APDR convened a task force consisting of diverse broad stakeholder viewpoints, drawing from organized radiology, academic and private practices.

Printed Thin Magnetic Films via Ternary Hybrid Diblock Copolymer Films Containing Magnetic Iron Oxide and Nickel Nanoparticles.

Ternary hybrid thin films composed of a diblock copolymer templating two types of nanoparticles (NPs) expand the functionality of binary systems, which renders them interesting for magnetic sensing or magnetic data storage applications. Herein, one-pot slot-die printed hybrid polystyrene--poly(methyl methacrylate) (PS--PMMA) thin films are prepared with iron oxide (magnetite, FeO, = 20 nm) and nickel NPs (Ni, = 46 nm) in one step by the advanced slot-die coating technique, which facilitates upscaling of fabrication. The evolution of the hybrid film morphology is probed with in situ grazing-incidence small-angle X-ray scattering and compared to that of a PS--PMMA thin film without NPs.
