AI Article Synopsis

  • The text discusses a new exact equation specifically for the transverse component of the electric field.
  • This electric field propagates in a longitudinal z direction, meaning it moves along or parallel to that axis.
  • The analysis is conducted in the context of an isotropic refractive-index distribution, which means the refractive index is uniform in all directions at any given point in the x-y plane.

Article Abstract

We derive an exact equation for the transverse component of the electric field propagating along a given longitudinal z direction in the presence of an isotropic refractive-index distribution n(x,y).

Transverse Momentum Distributions from Lattice QCD without Wilson Lines.

Phys Rev Lett

December 2024

Physics Division, Argonne National Laboratory, Lemont, Illinois 60439, USA.

The transverse-momentum-dependent distributions (TMDs), which are defined by gauge-invariant 3D parton correlators with staple-shaped lightlike Wilson lines, can be calculated from quark and gluon correlators fixed in the Coulomb gauge on a Euclidean lattice. These quantities can be expressed gauge invariantly as the correlators of Coulomb-gauge-dressed fields, which reduce to the standard TMD correlators under principal-value prescription in the infinite boost limit. In the framework of large-momentum effective theory, a quasi-TMD defined from such correlators in a large-momentum hadron state can be matched to the TMD via a factorization formula, whose exact form is derived using soft collinear effective theory and verified at one-loop order.

Age-dependent changes in diameters of abdominal visceral arteries in children.

Faculty of Medicine, Department of Pediatric Surgery, Van Yüzüncü Yil University, Van, Turkey.

Purpose: The diameters of the abdominal aorta and its branches are affected by demographic properties of patients like age, sex or body mass index. Some researchers use the body of the first lumbar vertebra (L1) as an anatomical indicator to create an exact standard for diagnosing arterial aneurysms or stenoses. In this regard, this work designed to uncover relations of abdominal visceral arteries with L1 in normal children using their abdominopelvic computed tomography images.

Article Synopsis
  • The study focused on comparing oral lichen planus and related lesions due to their risk of becoming cancerous and the need to differentiate them from similar conditions.
  • Researchers conducted a survey among patients to collect sociodemographic and clinical data, analyzing this information using statistical tests.
  • The findings revealed distinct characteristics for each type of lesion, with lichen planus showing reticular patterns and the buccal mucosa being the most affected area, while proliferative verrucous leukoplakia was linked with significant epithelial dysplasia.

The freely jointed chain model with reversible hinges (rFJC) is the simplest theoretical model, which captures reversible transitions of the local bending stiffness along the polymer chain backbone (e.g., helix-coil-type of local conformational changes or changes due to the binding/unbinding of ligands).

Introduction: Acetabulum fractures involving both columns are complicated injuries to treat, and achieving satisfactory post operative reduction with less extensile approaches is difficult. These injuries often require dual approaches, associated with their own share of complications. The anterior intrapelvic approach (AIP) addresses both columns through a single approach, minimizing these complications.
