Excitons in the fractional quantum Hall effect.

Excitons, Coulomb-driven bound states of electrons and holes, are typically composed of integer charges. However, in bilayer systems influenced by charge fractionalization, a more interesting form of interlayer exciton can emerge, in which pairing occurs between constituents that carry fractional charges. Despite numerous theoretical predictions for these fractional excitons, their experimental observation has remained unexplored.

Belzutifan as the Primary Treatment of Bilateral Juxtapapillary Retinal Hemangioblastoma in a Patient With Von Hippel-Lindau Disease.

To describe the efficacy of belzutifan as a treatment for juxtapapillary retinal hemangioblastomas in patients with von Hippel-Lindau disease. A case and its findings were analyzed, and a systematic literature review was conducted using PubMed and Ovid MEDLINE. At a routine follow-up, a 63-year-old woman with a history of von Hippel-Lindau disease and slowly progressive bilateral juxtapapillary retinal hemangioblastomas presented with decreased visual acuity (VA) in the right eye resulting from significant lesion growth and an increase in central macular edema and exudate.

From the 100 Day Mission to 100 lines of software development: how to improve early outbreak analytics.

Since the COVID-19 pandemic, considerable advances have been made to improve epidemic preparedness by accelerating diagnostics, therapeutics, and vaccine development. However, we argue that it is crucial to make equivalent efforts in the field of outbreak analytics to help ensure reliable, evidence-based decision making. To explore the challenges and key priorities in the field of outbreak analytics, the Epiverse-TRACE initiative brought together a multidisciplinary group of experts, including field epidemiologists, data scientists, academics, and software engineers from public health institutions across multiple countries.

Adherence to follow-up ten years after hypospadias repair.

Introduction: Periodic follow-up prior to and after puberty to evaluate for long-term sequalae following hypospadias repair is commonly recommended. Few studies have evaluated this follow-up, especially into adulthood. This study aimed to evaluate adherence to routine postoperative follow-up appointments over 10 years following elective hypospadias repair.
