Flexoelectric polarization studies in bent-core nematic liquid crystals
(2015)The flexoelectric polarization ( P f ) of four bent-core nematic liquid crystals (LCs) has been measured using the pyroelectric effect. Hybrid aligned nematic cells are fabricated for measuring the pyroelectric response ... -
Effective long-range interlayer interactions and electric-field-induced subphases in ferrielectric liquid crystals
(2016)Microbeam resonant x-ray scattering experiments recently revealed the sequential emergence of electric- field-induced subphases (stable states) with exceptionally large unit cells consisting of 12 and 15 smectic layers. ... -
Anomalous temperature dependence of layer spacing of de Vries liquid crystals: Compensation model
(2016)Smectic liquid crystals that exhibit temperature independent layer thickness offer technological advantages for their use in displays and photonic devices. The dependence of the layer spacing in SmA and SmC phases of de ... -
Spontaneous helix formation in non-chiral bent-core liquid crystals with fast linear electro-optic effect
(2016)Liquid crystals (LCs) represent one of the foundations of modern communication and photonic technologies. Present display technologies are based mainly on nematic LCs, which suffer from limited response time for use in ... -
Dielectric and electro-optic studies of a bimesogenic liquid crystal composed of bent-core and calamitic units
(2014)A bimesogen, BR1, composed of a bent-core and calamitic unit, linked laterally via a flexible spacer is investigated by dielectric and electro-optic techniques. X-ray results show the presence of clusters in the nematic ... -
Effect of molecular-scale surface morphology on the surface melting of liquid crysals on self-assembly monolayers
(2014)We devised liquid crystal cell substrates with different surface roughnesses at the molecular scale by controlling the density of two types of trichlorosilanes with different alkyl chain lengths. We investigated surface ... -
Congruent Visual Speech Enhances Cortical Entrainment to Continuous Auditory Speech in Noise-Free Conditions.
(2015)Congruent audiovisual speech enhances our ability to comprehend a speaker, even in noise-free conditions. When incongruent auditory and visual information is presented concurrently, it can hinder a listener's perception ... -
The cortical representation of the speech envelope is earlier for audiovisual speech than audio speech.
(2014)Visual speech can greatly enhance a listener's comprehension of auditory speech when they are presented simultaneously. Efforts to determine the neural underpinnings of this phenomenon have been hampered by the limited ... -
ViSQOL: an objective speech quality model
(2015)This paper presents an objective speech quality model, ViSQOL, the Virtual Speech Quality Objective Listener. It is a signal-based, full-reference, intrusive metric that models human speech quality perception using a ... -
Hierarchical elasticity of bimesogenic liquid crystals with twist-bend nematic phase
(2015)in 2001, Dozov predicted that twist-bend nematic phase can be spontaneously formed when K 33 < 0 and K 11/K 22 > 2, and this phase has recently been discovered in bimesogens. To verify Dozov's hypothesis, we have measured ... -
