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 ...

Paradoxes and Antinomies in the Professional Acting of Teachers
Forum: Qualitative Social Research, 2000 Teachers continually experience boundaries in their work which are almost impossible to overcome. Particular acts, contradictory in themselves, hinder the development of pupils' learning processes.

Advanced Materials, EarlyView.This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.

Large-Scale Conformational Changes and Protein Function: Breaking the in silico Barrier
Frontiers in Molecular Biosciences, 2019 Large-scale conformational changes are essential to link protein structures with their function at the cell and organism scale, but have been elusive both experimentally and computationally.

Why classical certification is impossible in a quantum world [PDF]
Quantum Information Processing, 2011 We give a simple proof that it is impossible to guarantee the classicality of inputs into any mistrustful quantum cryptographic protocol. The argument illuminates the impossibility of unconditionally secure quantum implementations of essentially classical tasks such as bit commitment with a certified classical committed bit, classical oblivious ...

Advanced Materials, EarlyView.Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

A Classically-Based Theory of Impossible Worlds
Notre Dame Journal of Formal Logic, 1997 In the author's metaphysics a situation is an abstract object which encodes a set of propositions, where a proposition is a \(0\)-ary property. A possible world encodes a maximal consistent set of propositions and an impossible world encodes a maximal set of propositions which is not consistent.

Optofluidic Raman Analysis and Capacity Recovery in Li‐ion Cells
Advanced Materials Technologies, EarlyView.Operando Raman spectroscopy is used to monitor the degradation of commercial Li‐ion cells. Using a microfluidic access port, small amounts of electrolyte are sampled into a hollow‐core optical fibre, where fibre‐enhanced Raman analysis reveals Li+ solvation changes and solvent evolution.

Advanced Materials Technologies, EarlyView.We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...
