2014 We measured compressibility and splay elastic moduli, and the mobility of dislocations of the lamellar phase of C12E5-H2O system. The compressibility modulus has a usual value (2.5 x 107 dyn/cm2) while the splay modulus is small (6 x 10-8 dyn) and the mobility is high (6 x 10-7 cm2 sg-1). These results are used to calculate the permeation coefficient. These values are then discussed with r...

Flexoelectric effects in nematic liquid crystals are well known to occur through combinations of either the sum or the difference of the splay and bend polarizations. In this work we examine the role of both mechanisms in the switching of zenithally bistable nematic devices, and conclude that both can cause bistable switching. Interestingly, we find that the most important flexoelectric coeffic...

In this paper, we proposed a new encryption algorithm called KIST. This algorithm uses an asynchronous key sequence and a splay tree. It is very efficient in the usage of both space and time. Some elementary security tests have been done.

We study the dynamic optimality conjecture, which predicts that splay trees are a form of universally efficient binary search tree, for any access sequence. We reduce this claim to a regular access bound, which seems plausible and might be easier to prove. This approach may be useful to establish dynamic optimality.

Starting from a microscopic definition of an alignment vector proportional to the polarization, we discuss the hydrodynamics of polar liquid crystals with local C infinity v symmetry. The free energy for polar liquid crystals differs from that of nematic liquid crystals (D infinity h) in that it contains terms violating the n --> -n symmetry. First we show that these Z2-odd terms induce a gener...

-A nematic layer with opposite boundary conditions (unidirectional planar and homeotropic) is considered, having strong anchoring at the planar wall. It is known that a periodic deformation of splay-type can intervene between the aperiodic hybrid alignment and undistorted planar state as one decreases the film thickness. This periodic state occurs due to the fact that the energetic cost for a m...

We show that defect-free splay-bend textures are less energetic compared to uniform states in liquid-crystalline phases that possess both quadrupolar (nematic) and octupolar (tetrahedratic) order. This is because, in such systems, there is a symmetry-allowed linear gradient term in the energy. Another unusual feature of these splay-bend textures is the fact that they have a non-homogeneous, spa...
