Contingent valuation (CV) has become one of the most widely used non-market valuation techniques. CV’s prominence is due to its flexibility and ability to estimate total value, including passive use value. Its use and the inclusion of passive use value in benefit-cost analyses and environmental litigation are the subject of a contentious debate. This paper discusses key areas of the debate over...

Communication signal processing applications often involve complex-valued (CV) functional representations for signals and systems. CV artificial neural networks have been studied theoretically and applied widely in nonlinear signal and data processing [1–11]. Note that most artificial neural networks cannot be automatically extended from the real-valued (RV) domain to the CV domain because the ...

Type 2 diabetes mellitus (T2DM) is an independent risk factor for cardiovascular (CV) comorbidities, with CV disease being the most common cause of death in adults with T2DM. Although glucocentric therapies may improve glycaemic control (as determined by glycated haemoglobin levels), evidence suggests that this approach alone has limited beneficial effects on CV outcomes relative to improvement...

BACKGROUND AND OBJECTIVES Although electrical cardioversion (CV) is effective in restoring sinus rhythm (SR) in patients with atrial fibrillation (AF), AF frequently recurs in spite of antiarrhythmic medications. We investigated the predictors of failed CV and AF recurrence after successful CV. SUBJECTS AND METHODS In 81 patients (M:F=63:18, 59.1+/-10.5 years old) with AF who underwent CV, cl...

The physical and chemical properties of the date (Phoenix dactylifera L.) fruit seeds from seven date samples (Soukari, Soulag, Barhi, Khulas, Rozaiz, Soughi and Monaif) were evaluated. Energy values of dried and ground seeds were found between 4340 kcal/kg (Barhi cv) and 4795 kcal/kg (Rozaiz cv). Also, while crude oil content of seeds were established between 4.68% (Khulas cv) and 7.96% (Monai...

BACKGROUND Vascular calcification has been recognized as a risk factor for cardiovascular (CV) events in patients with end-stage renal disease (ESRD). However, the association of carotid artery calcification (CAAC) with CV events remains unknown. The aim of this study was to elucidate whether CAAC is associated with composite CV events in ESRD patients. METHODS One-hundred thirty-three patien...

BACKGROUND In applications of supervised statistical learning in the biomedical field it is necessary to assess the prediction error of the respective prediction rules. Often, data preparation steps are performed on the dataset-in its entirety-before training/test set based prediction error estimation by cross-validation (CV)-an approach referred to as "incomplete CV". Whether incomplete CV can...

BACKGROUND Screening for Fabry disease (FD) increasingly reveals individuals without characteristic features and with a variant of unknown significance in the α-galactosidase A (GLA) gene. Cornea verticillata (CV) assessment, as a characteristic sign of FD, may be a valuable diagnostic tool to assess whether these individuals have a non-classical phenotype or no FD at all. METHODS We performe...

BACKGROUND Many barriers exist to conducting pediatric cardiovascular (CV) trials, and the majority of therapies used are not evidence based. Recent legislation has aimed to stimulate pediatric research and improve drug labeling. This study describes off-label use of CV medications in children hospitalized with congenital and acquired CV disease. METHODS AND RESULTS The 2005 Pediatric Health ...
