We report here on differential linear scan voltammetry, DLSV, that combines the working principles of linear scan voltammetry, LSV, and the numerous existing pulsed voltammetry techniques. DLSV preserves the information from continuous interrogation in voltage and high accuracy that LSV provides about electrochemical processes, and the much better sensitivity of differential pulsed techniques. ...

In this paper, we introduce an algorithm to delineate elementary forms on Digital Elevation Models (DEMs). Elementary forms are defined by constant values of fundamental morphometric properties and limited by discontinuities of these properties. A multiresolution segmentation technique was customized to partition the layers of altitude derivatives into homogeneous divisions through a self-scala...

Text The phase one results from the randomized Radial artery versus Saphenous Vein Patency (RSVP) trial are published in the current issue of the Journal [1]. Fifty-two patients had quantitative angiography with Thrombolysis in Myocardial Infarction (TIMI) flow assessment, approximately 3 months after coronary bypass graft surgery. A subset of 7 patients had in-vivo assessment of graft flow and...

PURPOSE To assess long-term anatomic and visual outcomes and associated complications of lens-sparing vitrectomy (LSV) for treatment of tractional retinal detachments (TRDs) associated with stages 4B and 5 retinopathy of prematurity (ROP). METHODS We performed a retrospective review of medical records and data analyses of consecutive patients who presented with stages 4B and 5 ROP and underwe...

in this study, simple, fast and reliable cyclic voltammetry (cv), linear sweep voltammetry (lsv), square wave voltammetry (swv) and differential pulse voltammetry (dpv) methods were developed and validated for determination of bosentan in pharmaceutical preparations. the proposed methods were based on electrochemical oxidation of bosentan at platinum electrode in acetonitrile solution containin...

O presente trabalho reporta o desenvolvimento de um novo método voltamétrico para análise de íons ouro(III) usando eletrodo de carbono impresso modificado com poli-L-histidina. O procedimento é baseado no acúmulo do complexo [AuCl 4 ], na superfície do eletrodo sob potencial de circuito aberto e tempo de acúmulo controlado. Parâmetros que influenciam na resposta, tais como: preparação do filme,...

Spoken Language Systems at Saarland University (LSV) participated this year with 5 runs at the TAC KBP English slot filling track. Effective algorithms for all parts of the pipeline, from document retrieval to relation prediction and response post-processing, are bundled in a modular end-to-end relation extraction system called RelationFactory. The main run solely focuses on shallow techniques ...

In order to study the structural changes in the intimal layer of varicose veins, we prospectively collected a total of 23 vein specimens from both the normal proximal thigh long saphenous (LSV) in 3 young trauma patients and from the unstripped proximal LSV near the sapheno-femoral junction and the distal calf blowouts in 10 primary varicose veins patients. Paraffin sections stained with hemato...

OBJECTIVES Pre-existing unsuspected wall changes in saphenous vein grafts have been implicated in the graft outcome. Pre-bypass assessment of the vein may identify grafts at high risk for failure. This study was conducted to evaluate preoperatively the quality of the long saphenous vein (LSV) wall with ultrasound and histology. DESIGN Prospective clinical study. MATERIAL AND METHODS Three p...

Extensive efforts have been devoted to improve the anode performance of a microbial fuel cell (MFC) by using modified carbon-based anode materials, but most of them did not recognize that the power performance measured by the commonly-used varying circuit resistance (VCR) or linear sweep voltammetry (LSV) method was overestimated due to the effect of anode capacitance. Here, we examined and com...
