Spectral imaging techniques are a powerful tool for surveillance and monitoring of degradation mechanisms in PV modules. Luminescence images solar modules have until recently been predominantly acquired controlled laboratory settings. Recent attempts made detecting luminescence daylight. This study aims to present proof concept detection photoluminescence with sunlight excitation. It enables se...

BACKGROUND The mechanism of pulmonary vein (PV) triggers of atrial fibrillation remains unclear. We performed adenosine (ADO) testing after PV isolation to characterize spontaneous dissociated PV rhythm and ADO-induced PV ectopy. METHODS AND RESULTS Seventy-four patients (61 men; age, 61±10 years) undergoing PV isolation for atrial fibrillation were studied. For each isolated PV, dissociated ...

In the hippocampus, the calcium-binding protein parvalbumin (PV) is expressed in interneurons that innervate perisomatic regions. PV in GABAergic synaptic terminals was proposed to limit repetitive GABA release by buffering of "residual calcium." We assessed the role of presynaptic PV in Ca(2+)-dependent GABA release in the hippocampus of PV-deficient (PV-/-) mice and wild-type (PV+/+) litterma...

We discuss the problem of construction of inference procedures which can manipulate with uncertainties measured in ordinal scales and fulfil to the property of strict monotonic­ ity of conclusion. The class of A-valuations of plausibility is considered where operations based only on information about linear or­ dering of plausibility values are used. In this class the modus ponens generating fu...

Radiofrequency catheter ablation of atrial fibrillation (AF) is an effective rhythm control strategy, and its efficacy has been proved to be superior to anti-arrhythmic drugs.1-3) Recently, the European Society of Cardiology’s 2010 revised guidelines for AF management suggested catheter ablation as the firstline treatment in patients with paroxysmal lone AF.4) When Haissaguerre et al.5) initial...

Mutations in the thyroid hormone receptor beta (TRbeta) gene result in resistance to thyroid hormone. However, it is unknown whether mutations in the TRalpha gene could lead to a similar disease. To address this question, we prepared mutant mice by targeting mutant thyroid hormone receptor kindred PV (PV) mutation to the TRalpha gene locus by means of homologous recombination (TRalpha1PV mice)....

INTRODUCTION The significance of intermittent tachycardia within a pulmonary vein (PV) during an episode of atrial fibrillation (AF) is unclear. The aim of this study was to determine the role that intermittent PV tachycardias play in AF. METHODS AND RESULTS In 56 patients with AF, segmental ostial ablation guided by PV potentials was performed to isolate the PVs. The characteristics of inter...

Solar photovoltaic (PV) arrays are providing an increasing fraction of global electrical demand, with an accelerating rate of new installations. Most of these employ conventional glass-fronted panels, but this type of PV array does not satisfy applications that require a light-weight, flexible PV generator. An option discussed in this article is to consider textiles for such solar cell substrat...

In this paper, we prove that S 2 can prove consistency of PV−, the system obtained from Cook and Urquhart’s PV [3] by removing induction. This apparently contradicts Buss and Ignjatović [2], since they prove that PV 6⊢ Con(PV−). However, what they actually prove is unprovability of consistency of the system which is obtained from PV− by addition of propositional logic and BASICe-axioms. On the ...
