avnrt, (atrioventricular nodal reentry tachycardia), atrial tachycardia and atrial flutter are 3 kinds of supraventricular tachycardia, which their mechanism are explained based on reentry. a 60-years-old man is presented with all of the above-mentioned arrhythmias, responsive to intravenous injection of adenosine. radiofrequency ablation of the slow pathway territories cured all of them. there...

Analysis of the neural code for sensory-motor latency in smooth pursuit eye movements reveals general principles of neural variation and the specific origin of motor latency. The trial-by-trial variation in neural latency in MT comprises a shared component expressed as neuron-neuron latency correlations and an independent component that is local to each neuron. The independent component arises ...

The aim of this work is to develop a template for component-based programs which can be used in different programming languages. First, we give a model of component based systems based on the unifying theory of programming. We define the concepts interface, contract and component, and component combination. The definition can be used as the basis for the component template development. We defin...

The transmission of social attitudes has been investigated as a possible model of cultural inheritance in a sample of 3810 twin pairs from the Australian National Health and Medical Research Twin Registry. Six social attitude factors were identified and univariate genetic models fitted to scores on each factor. A joint multivariate genetic analysis of the six attitude factors, church attendance...

the molecular sieves are selective adsorbents. they can adsorb some kind of molecules that are different in size or shape from the others. in separation of n-paraffins from iso-paraffins and aromatics, sa molecular sieve is the suitable adsorbent, and can adsorb n-paraffins to separate them from other hydrocarbons. in this paper equilibrium isotherms of n-cs, n-c6 and n-c7 from an inert solvent...

Multi-task learning is an essential yet practical mechanism for improving overall performance in various machine fields. Owing to the linguistic hierarchy, hierarchical joint model a common architecture used natural language processing. However, state-of-the-art models, higher-level tasks only share bottom layers or latent representations with lower-level thus ignoring correlations between at d...
