Tunable Generation of Spatial Entanglement in Nonlinear Waveguide Arrays.

Harnessing high-dimensional entangled states of light presents a frontier for advancing quantum information technologies, from fundamental tests of quantum mechanics to enhanced computation and communication protocols. In this context, the spatial degree of freedom stands out as particularly suited for on-chip integration. But while traditional demonstrations produce and manipulate path-entangled states sequentially with discrete optical elements, continuously coupled nonlinear waveguide systems offer a promising alternative where photons can be generated and interfere along the entire propagation length, unveiling novel capabilities within a reduced footprint.

Assessment of virtual bracket removal by artificial intelligence and thermoplastic retainer fit.

Introduction: Digital orthodontics is here to make our specialty more efficient, and the integration of artificial intelligence (AI) is no exception. This study aimed to compare the accuracy of a workflow involving virtual bracket removal (VBR) by AI to traditional bracket removal. A secondary objective was to compare the clinical fit of thermoplastic orthodontic retainers fabricated from 3-dimensional (3D) printed models created by each method.

Understanding the Values, Qualities, and Preferences of Patients in Their Relationships With Obstetrics and Gynecology Providers: Cross-Sectional Survey With a Mixed Methods Approach.

Background: The patient-provider relationship in obstetrics and gynecology (OBGYN) is uniquely complex due to the sensitive nature of examinations and topics. Patients often prefer health care providers who share similar racial, ethnic, gender, or linguistic backgrounds, particularly in sensitive health care situations, to improve communication and comfort, though historically, specific gender preferences for OBGYNs have not been evident.

Objective: This study aims to describe the values, qualities, and preferences of patients in their relationships with OBGYN providers.

Inhibition of SARS-CoV-2 3CLpro by chemically modified tyrosinase from .

Antiviral compounds are crucial to controlling the SARS-CoV-2 pandemic. Approved drugs have been tested for their efficacy against COVID-19, and new pharmaceuticals are being developed as a complementary tool to vaccines. In this work, a cheap and fast purification method for natural tyrosinase from (AbTyr) fresh mushrooms was developed to evaluate the potential of this enzyme as a therapeutic protein the inhibition of SARS-CoV-2 3CLpro protease activity .

Risk of sleep-disordered breathing in orthodontic patients: comparison between children and adolescents.

Objective: The aim of this study was to assess the risk of sleep-disordered breathing (SDB) in orthodontic patients and to evaluate the influence of sex, age, and orthodontic treatment in a cohort of subjects using the Pediatric Sleep Questionnaire (PSQ) screening tool.

Methods: Parents of 245 patients aged 5-18 years (11.4 ± 3.
