Advanced Intelligent Systems, EarlyView.This work presents compact, low‐voltage actuators based on electropermanent magnetic interactions. The actuators show good overall performance across key metrics and are implemented in wearable devices and untethered robots. Their ability to operate in different configurations and hold positions without energy input highlights their potential for ...

Sulfidic crosslinks in EPM: a strategy for advanced flexible EPM composites
Frontiers in Soft MatterEthylene–propylene rubber (EPM) is a fully saturated elastomer, which prevents its crosslinking by conventional accelerated sulfur curing that requires unsaturation. In this study, a hybrid curing approach is introduced to generate sulfidic crosslinks in

Chemistry – A European Journal, EarlyView.A donor–π–acceptor–π–donor (D–π–A–π–D) fluorophore bearing a U‐shaped dipyridophenazine core forms bifurcated hydrogen bonds with neutral donors such as sulfonamides or water. This interaction modulates both ground and excited states, enabling red‐shifted emission and enhanced photoluminescence in solution and solid state.

Minimal long-term neurobehavioral impairments after endovascular perforation subarachnoid hemorrhage in mice [PDF]
, 2017 Cognitive deficits are among the most severe and pervasive consequences of aneurysmal subarachnoid hemorrhage (SAH). A critical step in developing therapies targeting such outcomes is the characterization of experimentally-tractable pre-clinical models ...

Deep Underground Science and Engineering, EarlyView.The permeability variation of rocks during complete stress–strain processes was investigated. A mathematical model describing the influence of rock damage on permeability was constructed. The permeability–stress relationship between soft rock and hard rock was proposed.

Cost monotonicity, consistency and minimum cost spanning tree games [PDF]
, 2002 We propose a new cost allocation rule for minimum cost spanning tree games. The new rule is a core selection and also satisfies cost monotonicity. We also give characterization theorems for the new rule as well as the much-studied Bird allocation.

Mirror Neutrinos and the Early Universe
, 2000 I review the construction of the Exact Parity or Mirror Matter Model and explain how it solves the solar and atmospheric neutrino problems. The oscillation driven relic neutrino asymmetry amplification phenomenon is then used to demonstrate the ...

EPM ephemerides and relativity [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractIn the seventies of the last century the EPM ephemerides (Ephemerides of Planets and the Moon) of IAA RAS originated and have been developed since that time. These ephemerides are based upon relativistic equations of motion of celestial bodies and light rays and upon relativistic time scales. The updated model of EPM2008 includes the new values
