Objective To evaluate the performance of dual internally cooled wet tip (ICWT) radiofrequency electrodes in comparison to (ICT) electrodes.Methods Twenty ablation zones were created for each type electrodes. Planned procedure time was 6 min. Diameters zone along x-, y-, and z-axes (Dx, Dy, Dz), sphericity, quantitative sphericity measurement, volume measured compared between two electrode types...

Current models of hierarchical processing in auditory cortex have been based principally on anatomical connectivity while functional interactions between individual regions have remained largely unexplored. Previous cortical deactivation studies in the cat have addressed functional reciprocal connectivity between primary auditory cortex (A1) and other hierarchically lower level fields. The pres...

BACKGROUND AND AIMS Banana finger drop is defined as dislodgement of individual fruits from the hand at the pedicel rupture area. For some banana varieties, this is a major feature of the ripening process, in addition to ethylene production and sugar metabolism. The few studies devoted to assessing the physiological and molecular basis of this process revealed (i) the similarity between this pr...

Abstract Funding Acknowledgements Type of funding sources: None. Background/Introduction Magnetic resonance imaging (MRI) is very useful for planning the ablation ventricular tachycardias (VT) related to scar, since it allows identification anatomy, scar dense/border zone (DZ/BZ) and conduction channels (CC). However, access this test limited in many centres and, addition, artefacts generated b...

The present study is an electropalatographic and acoustic investigation of the fricatives /s, S/ and the affricates /ts, dz, tS, dZ/ based on data from five speakers of Majorcan Catalan and five speakers of Valencian Catalan. Results show that the articulatory characteristics of fricatives and affricates agree in several respects: the sounds traditionally labeled /S/ and /tS, dZ/ are alveolopal...

Psychophysics and brain imaging studies in deaf patients have revealed a functional crossmodal reorganization that affects the remaining sensory modalities. Similarly, the congenital deaf cat (CDC) shows supra-normal visual skills that are supported by specific auditory fields (DZ-dorsal zone and P-posterior auditory cortex) but not the primary auditory cortex (A1). To assess the functional reo...

Mice lacking a synaptic isoform of glutamic acid decarboxylase (GAD65) do not exhibit ocular dominance plasticity unless an appropriate level of GABAergic transmission is restored by direct infusion of benzodiazepines into the brain. To better understand how intracortical inhibition triggers experience-dependent changes, we dissected the precise timing requirement for GABA function in the monoc...

In this paper, a generalized expression for the flow field in axisymmetric extrusion process is suggested to be valid for any dies and the boundary shapes of the plastic deformation zone. The general power terms are derived and the extrusion force is calculated by applying upper bound technique for a streamlined die shape and exponential functions for shear boundaries. It is shown that assuming...

Average stress during shear bond testing, and deformation behaviour during nano-indentation testing were calculated for the bonding area as a bonding site for copolymerization with resin composite in dentine bonding systems. First average stress was calculated in the bonding area between bovine dentine and composite resin. Secondly, the plastic deformation zone size was calculated using an elas...

A better understanding of fluid-related processes such as poroelastic rebound of the upper crust and weakening of the lower crust beneath the volcanic arc helps better understand and correctly interpret the heterogeneity of postseismic deformation following great subduction zone earthquakes. The postseismic deformation following the 2011 Mw9.0 Tohoku earthquake, recorded with unprecedented high...
