Psychology and Psychotherapy: Theory, Research and Practice, EarlyView.Abstract Objectives Nature exposure may support young women in improving their relationship with their body, enhancing positive body image. However, the mechanisms remain still largely underexplored. A few qualitative studies provided valuable insights, but they lacked generalizability to the broader population of young women, since they often relied ...

Encrypting underwater acoustic communications: low-bandwidth and cross-layer challenges
The operational use of underwater acoustic communications, particularly in a military context, requires adequate security measures. The minimum level of security required is protection of the user payload in the message, so this is the way to start. Main

Subspace Acceleration for Efficient Nonlinear Water Wave Simulation
International Journal for Numerical Methods in Fluids, Volume 98, Issue 10, Page 1165-1180, October 2026.We introduce an exponentially weighted subspace acceleration technique to reduce GMRES iterations for solving the Poisson equation with time‐dependent coefficients in nonlinear, dispersive free‐surface flows governed by the incompressible Navier‐Stokes equations. The method significantly reduces memory requirements and computational complexity compared
