Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

open access: yesAdvanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

2D MOF with Intrinsic Porosity for Colorimetric Volatile Organic Compounds (VOCs) Detection

open access: yesAdvanced Materials, EarlyView.
An uncommon 2D MOF with intrinsic in‐plane porosity that can be mechanically exfoliated undergoes a distinct and reversible colour change upon exposure to various volatile organic compounds. ABSTRACT In this work, we report an uncommon 2D metal–organic framework (MOF) with intrinsic in‐plane porosity that undergoes a distinct and reversible colour ...

Evaluation of Penalty Corner Success Rates for Indoor Hockey Players

open access: yesIndonesian Journal of Physical Education and Sport Science
Study purpose. Penalty corner is a situation that can be used as an opportunity to increase the score in indoor hockey. However, sometimes players cannot take advantage of this situation, so the opportunity to score a goal is lost.

The Motherhood Wage Penalty in a Mediterranean Country: The Case of Spain [PDF]

open access: yes
We present evidence for the motherhood wage penalty in Spain as a representative Southern European Mediterranean country. We use the European Community Household Panel (ECHP, 1994-2001) to estimate, from both pool and fixed-effects methods, a wage ...

Room‐Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

open access: yesAdvanced Materials, EarlyView.
We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Nonparametric maximum likelihood estimation of probability densities by penalty function methods [PDF]

open access: yes
When it is known a priori exactly to which finite dimensional manifold the probability density function gives rise to a set of samples, the parametric maximum likelihood estimation procedure leads to poor estimates and is unstable; while the ...
