DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6   6   6 m liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019-2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light.

The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a combination of capable precision detectors, and by the massive far detector system located deep underground. This configuration sets up DUNE as a machine for discovery, as it enables opportunities not only to perform precision neutrino measurements that may uncover deviations from the present three-flavor mixing paradigm, but also to discover new particles and unveil new interactions and symmetries beyond those predicted in the Standard Model (SM).

We present the first results of the Fermilab National Accelerator Laboratory (FNAL) Muon g-2 Experiment for the positive muon magnetic anomaly a_{μ}≡(g_{μ}-2)/2. The anomaly is determined from the precision measurements of two angular frequencies. Intensity variation of high-energy positrons from muon decays directly encodes the difference frequency ω_{a} between the spin-precession and cyclotron frequencies for polarized muons in a magnetic storage ring.

Computerized tomography (CT) scanning, now widely used for the diagnosis and treatment planning of dental implant sites, can be more specifically useful with integrated computer software. In this instance, the potentially critical incisive foramen area at the premaxilla is analyzed to better under stand its configuration and volume relative to the placement of root-form implants.

Article Synopsis
  • Vasoocclusive crises, common in sickle cell hemoglobinopathy, can lead to significant bone pain and complications.
  • Previous reports on mandible infarction in sickle cell patients are rare and relied mostly on clinical examination.
  • This article discusses a case where a patient with sickle cell experienced mandible infarction, diagnosed using nuclear bone imaging, independent of infection or inflammation.

We cloned genes that code for Treponema hyodysenteriae antigens into Escherichia coli with the purpose of identifying protective antigens for vaccine development. Three different genomic libraries were screened with various antisera reactive with T. hyodysenteriae antigens.

A 28-year-old man with a previous history of Neissena infection presented with diminished vision, disc swelling, and panuveitis. Serologic tests revealed positive titers for both HIV and syphilis. Current epidemiology and treatment of such cases are discussed.

Article Synopsis
  • The NaCl/KCl symporter is a key transport system in animal cells for the transmembrane movement of sodium and potassium salts, essential for regulating cell volume and salt balance.
  • The system is sensitive to loop diuretics like furosemide, which inhibit its function, and is linked to conditions like essential hypertension.
  • Research using the MDCK kidney epithelial cell line has revealed the symporter's mechanisms, cooperative ion binding behavior, and the characteristics that align it with similar transport systems across different organisms.

In a 31-year-old man, metastatic Aspergillus endophthalmitis developed after intravenous cocaine injection. His reluctance to admit to drug abuse resulted in delay of diagnostic and curative vitrectomy. Metastatic osteomyelitis also developed, underscoring the need for careful surveillance for other systemic manifestations of fungemia.
