Locked-floating-solid to locked-smectic transition in colloidal systems.
We investigate two-dimensional melting of a colloidal system in the presence of a one-dimensional periodic substrate potential created by two interfering laser beams. We study the commensurability ratio p=sqrt[3]a/2d=2 with a the mean particle distance and d the period of the periodic potential. In contrast with the previously investigated case p=1, here we observe that melting of the locked-fl...
متن کاملTransition from the locked in to the completely locked-in state: a physiological analysis.
OBJECTIVE To clarify the physiological and behavioral boundaries between locked-in (LIS) and the completely locked-in state (CLIS) (no voluntary eye movements, no communication possible) through electrophysiological data and to secure brain-computer-interface (BCI) communication. METHODS Electromyography from facial muscles, external anal sphincter (EAS), electrooculography and electrocortico...
متن کاملInfinitesimally Locked Self-Touching Linkages with Applications to Locked Trees
Recently there has been much interest in linkages (bar-and-joint frameworks) that are locked or stuck in the sense that they cannot be moved into some other configuration while preserving the bar lengths and not crossing any bars. We propose a new algorithmic approach for analyzing whether planar linkages are locked in many cases of interest. The idea is to examine self-touching or degenerate f...
متن کاملSmectic A to smectic A phase transition
2014 We investigate properties of the Meyer-Lubensky free energy introduced in the description of the nematic to smectic A phase transition, and show that a new transition from a smectic A to another smectic A is possible for some values of the parameters used in the theory. The recent observations by G. Sigaud et al. may be interpreted within this context. LE JOURNAL DE PHYSIQUE TOME 40, JUIN ...
متن کاملDiscrete Phase-Locked Loop Systems and Spreadsheets
This paper demonstrates the use of a spreadsheet in exploring non-linear difference equations that describe digital control systems used in radio engineering, communication and computer architecture. These systems, being the focus of intensive studies of mathematicians and engineers over the last 40 years, may exhibit extremely complicated behavior interpreted in contemporary terms as transitio...
