The incidence and significance of fusion of the QRS complex during resetting of sustained ventricular tachycardias (VTs) was determined in 53 VTs induced by programmed stimulation in 46 patients with prior myocardial infarction. All 53 VTs were reset with one or two extrastimuli delivered at the right ventricular apex (RVA); 29 (54.7%) demonstrated fusion of the VT QRS complex coincident with t...

Introduction. To describe anatomical and functional features in one patient with 10 years of severe vitreomacular traction syndrome (VTS) without functional damage demonstrated by optical coherence tomography (OCT). Patient and Methods. One patient with a history of 10 years VTS, with best-corrected visual acuity of 20/32, was followed up with OCT. Follow-up examinations, 3 months for the first...

We examine the possibility for precise determination of |Vts| (and |Vtd/Vts|) from the exclusive decays, B → Kl+l−, B → K∗l+l− (and B → πl+l−, B → ρl+l−). We show that the ratio |Vts| can be extracted experimentally with a small theoretical uncertainty from hadronic form–factors, if we appropriately constrain kinematical regions of q2. We also give detailed analytical and numerical results on t...

The constant increase of switching power converters in distribution and transmission grids pushes the need for harmonic measurements. Recent literature has shown that inductive Voltage Current Instrument Transformers (VTs CTs) can be used measurements, but their accurate frequency characterization involves use quite costly instrumentation. In this context, paper proposes an industry oriented te...

The mixed-valent radical cation of a styrylruthenium-modified meso-tetraarylzinc porphyrin forms a mixture of three different valence tautomers (VTs) in CH2Cl2 or 1,2-C2H4Cl2 solutions. One of these VTs has the charge and spin delocalized over the porphyrin and the styrylruthenium moieties, while the other two display charge and spin localization on just one of the different redox sites. The re...

Severe or profound deafness in hearing impaired children, can curb their ability to speak due to the lack of auditory feedback. There has been a considerable attempt in developing commercial speech training aids for such children which give feedback of acoustic and articulatory parameters. Speech training aids based on visual feedback of vocal tract shape (VTS) are reported to be useful for the...

BACKGROUND Implantable cardioverter-defibrillators (ICDs) reduce the risk of sudden cardiac death. The objective of this study was to evaluate whether testing of antitachycardia pacing (ATP) for induced ventricular tachycardias (VTs) at predischarge examination can predict ATP success during follow-up. METHODS AND RESULTS The study covers 200 consecutive patients who received ICD implants fro...

Discriminative classifiers are a popular approach to solving classification problems. However one of the problems with these approaches, in particular kernel based classifiers such as Support Vector Machines (SVMs), is that they are hard to adapt to mismatches between the training and test data. This paper describes a scheme for overcoming this problem for speech recognition in noise by adaptin...

249 enteropathogenic Escherichia coli (EPEC) strains from faecal samples of 90 children with diarrhoea were examined for verotoxin (VT) production. Polymyxin B extracts of 61 strains belonging to 9 serogroups from 35 children produced various verotoxins (VTs). The titre of these various VTs ranged from I :40 to I: 12HO. Of the 26 (43.6%) adherent strains, 19 (73%) exhibited localized adhere...

PURPOSE We compared the results from a video-assisted thoracoscopic sympathectomy (VTS) at the T4 denervation level with those from a VTS at the T3 level for the treatment of palmar hyperhydrosis (PH). METHODS Seventy patients with PH were prospectively followed for VTS at the T3 or T4 denervation levels for 6 months. The end points of this study were: absence of PH, compensatory hyperhydrosi...
