The phenomenon known as Watson-Crick complementarity is basic both in the experiments and theory of DNA computing. While the massive parallelism of DNA strands makes exhaustive searches possible, complementarity constitutes a powerful computational tool. It is also very fruitful to view complementarity as a language-theoretic operation: \bad" words obtained through a generative process are repl...

In this study the acoustic and articulatory variabilities of speakers with different palate shapes were compared. Since the cross-sectional area of the vocal tract changes less for a slight change in tongue position if the palate is domeshaped than if it is flat, the acoustic variability should be greater for flat palates than for domeshaped ones. Consequently, it can be hypothesized that speak...

The transitional Reynolds numbers for different patterns are available and a proposed transitional map is also provided in this paper. The transition of falling-films on flat tubes is studied in this work. Water and ethylene glycol are used as working fluids, for falling-film experiments conducted under adiabatic conditions, without an imposed vapor flow. The flow patterns are recorded using a ...

The problem of merging General Relativity with Quantum Field Theory is known as Quantum Gravity. One aspect of this merged theories is that at the Planck scale, spacetime could be subjected to topology and metric fluctuations[1]. Such a fluctuating spacetime is known under the name of “spacetime foam” which can be taken as a model for the quantum gravitational vacuum. At this scale of lengths (...

introduction: aphasia is a language disorder resulting from a lesion in the cerebral cortex. in this case report, we present a polyglot patient who recovered from aphasia by speaking his newly active learned language case report: a 69 years old male referred with acute onset right hemiparesis and global aphasia. after imaging, he treated with 75 mg r-tpa (0.9 mg/kg). after the fourth day of hos...

cerebral palsy (cp) is the most common motor disability in children, usually occurring during fetal development; before, during, or shortly after birth, or during infancy. cp takes place in about 2.1 per 1,000 live births .there is no exact reason but birth injury or inflammation of the central nervous system, infections and hypoxia are related risk factors of this disease. often, symptoms incl...

We present a computational method to generate a trompe l’œil on a paper, a 2D image depicting a virtual 3D model in such a way that the model appears to be a real 3D entity when a person views the printed image from specific viewpoint. This method is similar to augmented reality methods which show a virtual 3D model on top of a real world image captured by a camera considering photometric match...

Given the QRS width, the intraventricular conduction delay could not be explained solely by the left anterior hemiblock (LAHB). Placement of the rightward precordial leads V1–V2 one intercostal (IC) space above the conventional level uncovered a terminal R-wave suggestive of complete right bundle branch block (RBBB) (Fig. 1). Although there might be a contributing role for delayed activation of...
