An n-bit coil is a sequence of length n binary strings which corresponds to an induced cycle in the n-dimension hypercube. Coils have a variety of applications and usually the longer the coil the more useful it is in the application. The longest possible coils for n ≤ 7 were found by exhaustive search. Several heuristic based computational techniques including stochastic hill-climbing technique...

A five turn coil of magnet wire sandwiched between two soft contact lenses served as a magnetic search coil to measure horizontal and vertical eye movements in humans. The lens was adhered to the eye for 35 min by periodically misting the eye with distilled water; during this time the records of eye position showed that the lens remained firmly attached to the eye. Using this sensor, no topical...

This paper presents a new method called vespiary regular hexagonal (VRH) model in order to calculate parasitic capacitance between conductor wire filaments of one turn of coil (OTC) and between conductor wire filaments and liner and also total capacitance of one turn of the helix magneto flux cumulative generator (MCG) coil include single-layer conductor wire filaments in form of rectangular cr...

PURPOSE To examine the conjugacy of lid saccades in normal subjects. METHODS Saccades of both upper eyelids were recorded simultaneously by means of small, lightweight, magnetic search coils, fixed on each lid. Subjects then made vertical eye saccades between fixed targets. The associated eye saccades were recorded simultaneously by means of magnetic search coils. The authors further examined...

Models of protein evolution are used to describe evolutionary processes, for phylogenetic analyses and homology detection. Widely used general models of protein evolution are biased toward globular domains and lack resolution to describe evolutionary processes for other protein types. As three-dimensional structure is a major constraint to protein evolution, specific models have been proposed f...

Definition of the unfolded state of proteins is essential for understanding their stability and folding on biological timescales. Here, we find that under near physiological conditions the configurational ensemble of the unfolded state of the simplest protein structure, polyalanine alpha-helix, cannot be described by the commonly used Flory random coil model, in which configurational probabilit...

Saccadic eye movements of various sizes and directions were registered simultaneously with the scleral search coil and a fifth-generation Dual Purkinje image eyetracker. Comparison of the search coil and the Purkinje image tracker records reveal considerable dynamic deviations during and immediately after the saccade, which we ascribe to the movements of the eye lens relative to the optical axi...

Our goal is to review vestibulo-oculomotor reflex (VOR) studies on several peripheral vestibular disorders (Ménière's disease, vestibular neuritis, benign paroxysmal positional vertigo, superior canal dehiscence syndrome, and vestibular neuroma), using the scleral search coil (SSC) technique. Head movements are detected by vestibular receptors and the elicited VOR is responsible for compensator...

introduction: traumatic arteriovenous fistula (avf) called to an abnormal relationship between artery and vein which occurs in 10% of arterial traumas. if treatment of avf due to trauma delayed, different outcomes including heart failure, varices and varicose ulcers may accure. in case of chronic traumatic avf, open surgery may lead to remarkable outcomes, presence of many lateral veins and var...
