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

Advanced 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 ...

The asymmetric cosine distribution [PDF]

Asymmetry
In this article, we propose and study an improved version of the cosine distribution. Its main features are to be with support [-1, 1], to be mainly asymmetric by construction, and to be simple and flexible from a functional point of view, in particular,

LOCAL C-COSINE FAMILIES AND N-TIMES INTEGRATED LOCAL COSINE FAMILIES

Taiwanese Journal of Mathematics, 2004
For the investigation of ill-posed first-order abstract Cauchy problems, the theory of \(C\)-semigroups and \(n\)-times integrated semigroups has been developed and intensively studied in the last 20 years. The main technical tool in these investigations was the exhausting use of vector-valued Laplace transforms theory.

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

Advanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Cosine of angle and center of mass of an operator

, 2010
We consider the notion of real center of mass and total center of mass of a bounded linear operator relative to another bounded linear operator and explore their relation with cosine and total cosine of a bounded linear operator acting on a complex ...

4D‐Printed Spin Crossover Metamaterials with Giant Programmable Positive or Negative Thermal Expansion

Advanced Materials, EarlyView.
Spin crossover composite filaments are implemented for the rational design of 4D‐printed mechanical metamaterials. The obtained bi‐material structures guided by a theoretical analysis based on analytical calculations and Finite Element Analysis simulations exhibit giant programmable positive or negative deformation with coefficients of thermal ...
