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.

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.

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.
