Advanced Optical Materials, EarlyView.It is demonstrated that in chiral ferroelectric nematic liquid crystals sandwiched between electrically conducting transparent plates, the reflection color can be reversibly tuned by electric fields applied along the helix axis. The proposed theoretical model, assuming field‐induced coiling of the helix axis, accounts for all observations.

Virtual Sound Localization by Blind People
Archives of Acoustics, 2015 The paper demonstrates that blind people localize sounds more accurately than sighted people by using monaural and/or binaural cues. In the experiment, blind people participated in two tests; the first one took place in the laboratory and the second ...

Custom large scale integrated circuits for spaceborne SAR processors [PDF]
The application of modern LSI technology to the development of a time-domain azimuth correlator for SAR processing is discussed. General design requirements for azimuth correlators for missions such as SEASAT-A, Venus orbital imaging radar (VOIR), and ...

The RHIC azimuth quadrupole: "perfect liquid" or gluonic radiation?
, 2007 Large elliptic flow at RHIC seems to indicate that ideal hydrodynamics provides a good description of Au-Au collisions, at least at the maximum RHIC energy.

Advanced Optical Materials, EarlyView.Hexagonal arrays of silicon nanodisks are proposed to control 1.5 µm emission of Er3+ ions. Toroidal dipole resonance of the nanodisk array generates accessible magnetic hot spots at the surface, leading to enhanced and highly directional magnetic dipole emission along the surface‐normal direction via the magnetic Purcell effect.

Servomechanism for Doppler shift compensation in optical correlator for synthetic aperture radar [PDF]
, 1980 A method and apparatus for correcting Doppler shifts in synthetic aperture radar data is described. An optical correlator for synthetic aperture radar data has a means for directing a laser beam at a signal film having radar return pulse intensity ...

Advanced Robotics Research, EarlyView.This article presents dielectric elastomer switch (DES) materials, based on composite thin films. Alignment of graphite flakes due to their physical confinement within the thin films lead to much stronger piezoresistive responses than bulk composites, while their durability exceeds that of conventional liquid‐based DES materials.

Advanced Robotics Research, EarlyView.This work presents the MicroRoboScope, a highly integrated, compact, and portable microrobotic experimentation platform combining electromagnetic and acoustic actuation with real‐time visual feedback into a single, end‐to‐end device. The system enables closed‐loop control and tracking algorithm experimentation within an accessible and unified hardware ...

Axial symmetry breaking in self-induced flavor conversion of supernova neutrino fluxes
, 2013 Neutrino-neutrino refraction causes self-induced flavor conversion in dense neutrino fluxes. For the first time, we include the azimuth angle of neutrino propagation as an explicit variable and find a new generic multi-azimuth-angle (MAA) instability ...

Advances in Electroactive Liquid Crystal Elastomers for Intelligent Robotics and Electronics
Advanced Robotics Research, EarlyView.Electroactive liquid crystal elastomers (eLCEs) integrate molecular anisotropy with electrical functionality to enable programmable actuation and reconfigurable electronics. This review classifies eLCEs into robotic actuators and adaptive electronics, summarizes key actuation mechanisms, and highlights fabrication strategies that bridge materials to ...
