Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb[Formula: see text] of [Formula: see text] TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with [Formula: see text] GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between [Formula: see text] GeV and [Formula: see text] GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presented.

Background: Current protocols endorse biopsies for men with Prostate Imaging-Reporting and Data System (PI-RADS v2.1) scores ≥3. However, the subjective nature of PI-RADS can lead to increased false positives and unnecessary biopsies.

Background: Duchenne muscular dystrophy is primarily a disease of progressive muscle degeneration affecting the whole body. It is important to preserve the patients' walking ability as long as possible. Inconclusive information on Duchenne muscular dystrophy gait pattern is available for the lower body and missing for the upper body.

Rotational photonic spin Hall effect.

Nanophotonics

November 2023

Key Laboratory of Low-Dimensional Quantum Structures and Quantum Control of Ministry of Education, Synergetic Innovation Center for Quantum Effects and Applications, School of Physics and Electronics, Hunan Normal University, Changsha 410081, China.

Multidimensional manipulation of photonic spin Hall effect (PSHE) has attracted considerable interest due to its potential in a wide variety of spin-based applications. Plenty of research efforts have been devoted to transverse or longitudinal spin-dependent splitting; however, the splitting pattern that can self-rotate in a three-dimensional (3-D) space appears to be missing in literature. In this paper, we introduce a novel 3-D rotational PSHE, which can be realized and tuned using well-designed Pancharatnam-Berry phase metasurfaces.

Introduction/background: Venous sinus thrombosis hypercoagulable states leads to delayed drainage of blood from the brain; consequently, resulting in cerebral oedema, raised intracranial pressure, or stroke. Causes are variable, including severe dehydration, infections, cancers, sinusitis, and brain surgery. The commonest symptoms are headache, seizures, and unconsciousness.

Article Synopsis
  • Bertolotti syndrome (BS) is a condition often overlooked in young people with chronic lower back pain, linked to unusual lumbosacral vertebrae.
  • A case study of a 19-year-old woman showed BS was diagnosed after imaging confirmed fusion of a vertebra, leading to significant pain and movement restrictions.
  • The patient opted for conservative treatment with medication and exercise, resulting in a full recovery at the six-month follow-up, highlighting the need for better awareness of BS in chronic pain assessments.
