Integration of Through-Sapphire Substrate Machining with Superconducting Quantum Processors.

A sapphire machining process integrated with intermediate-scale quantum processors is demonstrated. The process allows through-substrate electrical connections, necessary for low-frequency mode-mitigation, as well as signal-routing, which are vital as quantum computers scale in qubit number, and thus dimension. High-coherence qubits are required to build fault-tolerant quantum computers and so material choices are an important consideration when developing a qubit technology platform.

What role did serious mental illness play in Jackson Pollock's drip paintings? Abstract expressionism and possible links to serious mental illness and encrypted images (polloglyphs).

The link between creativity and serious mental illness (SMI) is widely discussed. Jackson Pollock is one example of a giant in the field of art who was both highly creative and experiencing an SMI. Pollock created a new genre of art known as abstract expressionism ("action painting") defined as showing the frenetic actions of painting.

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.
