Total Distance Walked After Hip Surgery Identifies Older Patients With Sarcopenia

Nursing &Health Sciences, Volume 27, Issue 2, June 2025.
ABSTRACT This study aims to determine the optimal cut‐off point for total walking distance on the day of hospital discharge to identify older adults at high risk of sarcopenia following hip fracture surgery. A prospective observational study included 135 patients aged > 65 years who underwent hip fracture surgery.

Active Shortening Simultaneous to Normal Faulting Based on GNSS, Geophysical, and Geological Data: The Seismogenic Ventas de Zafarraya Fault (Betic Cordillera, Southern Spain)

Tectonics, Volume 43, Issue 2, February 2024.
Abstract The central Betic Cordillera, southern Spain, is affected by an uplift related to the NNW–SSE Eurasia‐Nubia convergence and shallow ENE–WSW orthogonal extension accommodated by the extensional system of the Granada Basin. The combination of geophysical, geodetic, and geological data reveals that the southwestern boundary of this extensional ...

Universal self-gravitating skyrmions

Journal of High Energy Physics
The self-gravitating skyrmion is an exact solution of the Einstein SU(2)-Skyrme model describing a topological soliton with baryon number B = 1, living in a 4-dimensional space-time in the presence of a cosmological constant. Here we show that, using the

Systems of Interaction between the First Sedentary Villages in the Near East Exposed Using Agent-Based Modelling of Obsidian Exchange

Systems, 2016
In the Near East, nomadic hunter-gatherer societies became sedentary farmers for the first time during the transition into the Neolithic. Sedentary life presented a risk of isolation for Neolithic groups.
