Radial coordinates for defect CFTs
, 2018 We study the two-point function of local operators in the presence of a defect in a generic conformal field theory. We define two pairs of cross ratios, which are convenient in the analysis of the OPE in the bulk and defect channel respectively.

Oral Manifestations of Non Vascular Ehlers‐Danlos Syndrome Cross‐Sectional Study
Oral Diseases, EarlyView.ABSTRACT Background Ehlers–Danlos syndromes are rare hereditary connective tissue disorders; however, their oral manifestations remain poorly characterized in molecularly confirmed individuals. The aim of this study was to describe the oral phenotype of patients with non‐vascular Ehlers‐Danlos syndromes compared to healthy controls.

Nonlinear Dynamic Analysis of Rotor Rub-Impact System
Shock and Vibration, 2019 A dynamic model of a double-disk rub-impact rotor-bearing system with rubbing fault is established. The dynamic differential equation of the system is solved by combining the numerical integration method with MATLAB.

The Journal of Physiology, EarlyView.Abstract figure legend Time‐resolved estimation of cardiac rhythmicity parameters. A pipeline is shown for the estimation of the fluctuating cardiac parameters, based on the Poincaré plot. The Poincaré plot illustrates the successive changes in interbeat intervals (IBI).

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons
Communications on Pure and Applied Mathematics, Volume 79, Issue 5, Page 1151-1298, May 2026.Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Radon transforms and the SYK model
Journal of High Energy PhysicsMotivated by recent work on the Sachdev-Ye-Kitaev (SYK) model, we consider the effect of Radon or X-ray transformations, on the Laplace eigenfunctions in hyperbolic Bolyai-Lobachevsky space.

SciPost Physics CoreWe study the entanglement properties in non-equilibrium quantum systems with the $SU(1,1)$ structure. Through Möbius transformation, we map the dynamics of these systems following a sudden quench or a periodic drive onto three distinct trajectories on ...

Improved Mood Following Cold‐Water Immersion: A Comparison of Differing Exposure Durations
Lifestyle Medicine, Volume 7, Issue 2, April 2026.ABSTRACT Background Cold‐water therapy is gaining popularity as a mood‐enhancing intervention. However, immersion protocols vary, particularly in terms of temperature and duration. This study examined whether different durations of cold‐water immersion produce differential effects on mood.
