Pulsed Field ablation (PFA) is a promising strategy for treatment of cardiac arrhythmias. But there are unresolved issues pertaining to its safety and efficacy, specifically microbubbles lesion homogeneity. Conventional electrode designs result in the surface be largely contact with blood, leading electrolysis during PFA. Additionally, blood electrodes provides conductive path energy, directing...

BACKGROUND To evaluate changes in health-related quality of life (HRQOL) in different sub-groups of a cohort of patients with typical atrial flutter (AFL) treated with cavotricuspid isthmus (CTI) radiofrequency catheter ablation. METHODS 95 consecutive patients due to undergo CTI ablation were enrolled in a study involving their completion of two SF-36 HRQOL questionnaires, before ablation an...

Spinal cord injury (SCI) frequently results in neuropathic pain. However, the pathophysiology underlying this pain is unclear. In this study, we compared clinical examination, quantitative sensory testing (QST) and somatosensory evoked potentials (SEPs) in SCI patients with and without pain below spinal lesion level, with a control group of 20 subjects without injury. All patients had a traumat...

In a polymer membrane fuel cell more than half of the chemical energy of hydrogen is converted to heat during generation of electricity. This causes an increase in the cell temperature. The Cooling field design has a significant role in cell cooling. The cell's performance and stability are reduced due to inappropriate heat dissipation. In this paper, the cooling flow and heat transfer in cooli...

Based on viscoplastic Anand’s model, structural stress of 8 8 InSb array detector dependent on indium bump sizes is systemically researched by finite element method. For the detector with underfill, simulation results show that as the diameters of indium bump decrease from 36μm to 20μm in step of 2μm, the maximum stress existing in InSb chip first reduces sharply, then increases flatly, and rea...

We consider neural field models in both one and two spatial dimensions and show how for some coupling functions they can be transformed into equivalent partial differential equations (PDEs). In one dimension we find snaking families of spatially-localised solutions, very similar to those found in reversible fourth-order ordinary differential equations. In two dimensions we analyse spatially-loc...

Introduction In computer numerical control (CNC) machining, the desired trajectory of the tool is defined by the part program. The purpose of the part program is to place the tool tip at specific coordinates relative to the part at every instant in time, leaving behind surfaces which form a workpiece of proper dimensions. Errors in the machined part dimensions are determined by the accuracy wit...

We present the case of a 54-year-old patient with a thermal cement burn. This rare case is a localised occupational chemical cement burn on the lower limbs, with no systemic involvement and favourable outcome. The lesion was induced by prolonged contact of the skin with cement and water during hot summer days.
