Recognizing, Experiencing, and Navigating Eating Disorder Echo Chambers on TikTok: A Qualitative Study

International Journal of Eating Disorders, EarlyView.
ABSTRACT Background Echo chambers are algorithmically curated environments characterized by reduced informational diversity and repeated exposure to content that reinforces existing attitudes and behaviors. Emerging research suggests TikTok's recommendation algorithm amplifies eating disorder (ED)‐related content among individuals with EDs, creating ED

Curvature and Solitonic Structures of Para-Sasakian Manifolds With Schouten–van Kampen Connection on the Tangent Bundle

Journal of Mathematics
This paper investigates the complete lift of para-Sasakian structures to the tangent bundle equipped with the Schouten–van Kampen connection (SVKC). By analyzing curvature tensors and soliton equations, we establish the existence of Ricci, Yamabe, and η ...

Predicting levetiracetam neuropsychiatric adverse effects using graph‐theoretical electroencephalographic network metrics in drug‐naive focal epilepsy: A multicenter longitudinal study

Epilepsia, EarlyView.
Abstract Objective Levetiracetam (LEV) is an antiseizure medication approved for focal and generalized epilepsy. Despite its efficacy, neuropsychiatric adverse effects (NP‐AEs) may lead to treatment discontinuation. Quantitative electroencephalographic (qEEG) graph‐theoretical analysis has emerged as a valuable tool for identifying neurophysiological ...

POSITIVITY OF RICCI CURVATURE UNDER THE KÄHLER–RICCI FLOW [PDF]

Communications in Contemporary Mathematics, 2006
In each complex dimension n ≥ 2, we construct complete Kähler manifolds of bounded curvature and non-negative Ricci curvature whose Kähler–Ricci evolutions immediately acquire Ricci curvature of mixed sign.

Comparison of two Euler equation sets in a Discontinuous Galerkin solver for atmospheric modelling (BRIDGE v0.9) [PDF]

Geoscientific Model Development
The implementation of a “classical” Discontinuous Galerkin (DG) solver for atmospheric flows is presented that is designed for efficient use in numerical weather prediction, climate simulations, and meteorological research both on the whole sphere and ...

Silicon differentially protects PSII and PSI photochemistry and preserves fatty acid metabolism in salt‐stressed Sorghum bicolor (L.)

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Silicon (Si) has been demonstrated to be an important element to enhance crop tolerance against salinity. Nevertheless, mechanisms underlying Si's mitigation of salt stress remains insufficiently explored and understood. This study aims to provide new insights into Si's impact on salt‐stressed Sorghum bicolor (L.) supplied or not ...

Uniqueness of instantaneously complete Ricci flows

, 2015
We prove uniqueness of instantaneously complete Ricci flows on surfaces. We do not require any bounds of any form on the curvature or its growth at infinity, nor on the metric or its growth (other than that implied by instantaneous completeness). Coupled
