Knowledge, Practice, and Socio‐Behavioral Determinants of Physical Activity Among Tunisian Medical Students: A Cross‐Sectional Study

Health Science Reports, Volume 9, Issue 10, October 2026.
ABSTRACT Background and Aims Physical inactivity has become a critical public health issue worldwide, contributing to numerous chronic diseases. As future healthcare providers, medical students' understanding and practice of physical activity are essential both for their personal health and their professional capacity to guide patients.

Singularities of Connection Ricci Flow and Ricci Harmonic Flow

, 2013
In this paper, we study the singularities of two extended Ricci flow systems --- connection Ricci flow and Ricci harmonic flow using newly-defined curvature quantities. Specifically, we give the definition of three types of singularities and their corresponding singularity models, and then prove the convergence. In addition, for Ricci harmonic flow, we

Non-local interaction in discrete Ricci curvature-induced biological aggregation

Royal Society Open Science
We investigate the collective dynamics of multi-agent systems in two- and three-dimensional environments generated by minimizing discrete Ricci curvature with local and non-local interaction neighbourhoods.

Synthesis and Characterization of Juglone‐Derived cu (II), Mn (II) and Zn (II) Complexes and Investigation of Their Cytotoxic Activities Against Lung and Colon Cancer Cells in Vitro and in Silico

Journal of Applied Toxicology, Volume 46, Issue 10, Page 3465-3477, October 2026.
ABSTRACT Three new Zn (II), Cu (II) and Mn (II) complexes have been synthesized from 5‐hydroxy‐1,4‐naphthoquinone (HNQ). Elemental analysis, magnetic susceptibility, UV–Vis, IR and Mass spectrometry have all been used to explore the structural characterization of these compounds.

Seasonal Variations in Aerosol Trace Element Source Contributions and Deposition Fluxes to the North Pacific Subtropical Gyre

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Trace elements deposited in the marine environment affect ocean biogeochemistry in numerous, complex ways. This study quantifies seasonal aerosol trace element (TE) fluxes and evaluates their variability and potential sources over a 2‐year period in the North Pacific subtropical gyre (NPSG). We established the Hawaii Aerosol Time Series (HATS),

“I think people's perception that her reading is good enough. That would be a worry to me.” Mother and child perspectives of school‐related reading for children with Down syndrome

Journal of Research in Special Educational Needs, Volume 26, Issue 4, October 2026.
Abstract There is growing interest in children's reading experiences, both volitional and those initiated by, or connected to, school‐related reading. However, the majority of this research focuses on the reading experiences of neurotypical children; limiting understanding and the potential to improve support for other groups of children.

The Ricci flow on the 2-sphere

Journal of Differential Geometry, 1991
The classical uniformization theorem, interpreted differential geomet-rically, states that any Riemannian metric on a 2-dimensional surface ispointwise conformal to a constant curvature metric. Thus one can con-sider the question of whether there is a natural evolution equation whichconformally deforms any metric on a surface to a constant curvature ...
