Advanced Esophageal Endoscopy.

Recent advancements in endoscopy, including high-definition imaging, virtual chromoendoscopy, and optical magnification, have enhanced our ability to visualize and diagnose certain esophageal diseases. Innovative endoscopic tools and procedures have been developed to broaden the scope of therapeutic options for treating patients with various esophageal conditions. This comprehensive review aims to elucidate the esophageal anatomy and major disorders from an endoscopist's perspective and explore recent advances in endoscopic treatment.

A Solid-State Source of Single and Entangled Photons at Diamond SiV-Center Transitions Operating at 80K.

Large-scale quantum networks require the implementation of long-lived quantum memories as stationary nodes interacting with qubits of light. Epitaxially grown quantum dots hold great potential for the on-demand generation of single and entangled photons with high purity and indistinguishability. Coupling these emitters to memories with long coherence times enables the development of hybrid nanophotonic devices that incorporate the advantages of both systems.

Electrical Properties of Thin ZrSe Films for Device Applications.

Measurements of key properties of the two-dimensional transition metal trichalcogenide ZrSe are reported. The bulk material was created by chemical vapor deposition and subsequently exfoliated to obtain thin films of varying thicknesses. The samples were then characterized by atomic force microscopy measurements and Raman spectroscopy and contacted by e-beam lithography.

Comparison of endoscopic sleeve gastroplasty versus surgical sleeve gastrectomy: a Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database analysis.

Background And Aims: Endoscopic sleeve gastroplasty (ESG) is an incisionless, transoral, restrictive bariatric procedure designed to imitate sleeve gastrectomy (SG). Comparative studies and large-scale population-based data are limited. Additionally, no studies have examined the impact of race on outcomes after ESG.
