Evaluation of just-in-time trauma training for international surgical military preparedness at a US Civilian Levell Trauma Center: A proof of concept.

Background: Increasing global conflicts continue to heighten the need for increased focus on preparedness for military physicians and surgeons. Simulation has recently been adopted by civilian surgical trainees to offset the problem of increased work hour restrictions and shift the current focus toward minimally invasive techniques. We hypothesized that just-in-time trauma training, incorporating both focused clinical and simulated experience at our civilian Level I Trauma Center, would increase the competence and confidence of international military physicians in trauma care.

Clinical Management Update of Oral Leukoplakia: A Review From the American Head and Neck Society Cancer Prevention Service.

Background: Oral potentially malignant disorders (OPMDs) occur in up to 4%-5% of the population, of which oral leukoplakia (OL) is the most common subtype. Predicting high-risk OL remains a challenge. Early diagnosis and effective treatment are thought to be of paramount importance to improve outcomes.

Holographically fabricated out-of-plane blazed gratings and channel waveguides in silica for integrated free-space beam delivery.

Grating couplers are widely used in integrated optics to generate free-space beams and facilitate localized interactions with systems such as atom or ion traps. However, etched devices often exhibit small-scale inconsistencies; exacerbated by the high index contrast of the devices, this can lead to phase errors, limiting devices to a sub-millimeter scale. Here we present the first demonstration, to our knowledge, of tilted, out-of-plane blazed gratings in planar silica fabricated by UV inscription using a 213 nm laser.

Biodiversity impacts of the 2019-2020 Australian megafires.

With large wildfires becoming more frequent, we must rapidly learn how megafires impact biodiversity to prioritize mitigation and improve policy. A key challenge is to discover how interactions among fire-regime components, drought and land tenure shape wildfire impacts. The globally unprecedented 2019-2020 Australian megafires burnt more than 10 million hectares, prompting major investment in biodiversity monitoring.
