In this paper, we attempt to capture the notion of usefulness in propositional language. We believe that classical implication captures a certain kind of usefulness, and name it strict usefulness. We say that a formula P is strictly useful to a formula Q under a formula set Γ if and only if P implies Q under Γ in classical propositional logic. We also believe that classical implication is too s...

This paper explores how dimensions of new product, specifically, originality and usefulness, influence word-of-mouth (WOM). In four studies, using lab and field setups, we find that originality and usefulness have different effects on WOM. We show that consumers spread more WOM about original products, but the valence of what they say depends on product usefulness. Thus, originality enhances th...

Research on information systems (IS) adoption and acceptance has frequently relied upon selfreported measures of system usefulness. In this study, we compare self-reported with computermonitored measures of usefulness. In a series of group experiments, participants were asked to assess the usefulness of three applications—two Generativity Support applications and one Baseline application that s...

hbme-l is an antimesothelial monoclonal antibody that recognizes an unknown antigen on microvilli of mesothelial cells. the antibody is only relatively specific for mesothelium and is used in the differential diagnosis of mesothelioma and adenocarcinoma within the context of an appropriate immuno-histochemical panel. hbme-l has also been reported to strongly and uniformly stain papillary and fo...

  Background Seizures may occur in as many as 1% of children. The most urgent type of seizures is generalized tonic-clonic seizures (GTCS). N-terminal prohormone of brain natriuretic peptide (NT‐proBNP) has been considered as a promising biomarker in numerous acute illnesses. We aimed to evaluate usefulness of NT‐proBNP for diagnosis of g...

this article is a comparative study of estimation power of artificial neural networks and autoregressive time series models in inflation forecasting. using 37 years iran’s inflation data, neural networks performs better on average for short horizons than autoregressive models. this study shows usefulness of early stopping technique in learning stage of neural networks for estimating time series...

ectopic paratliyroid adenoma might create a clinical dilemma in patients with hypercalcemia. radioisotopic scan is a sensitive and noninvasive method which can be useful in these patients. in this report a case of ectopic parathyroid adenoma is presented and the usefulness of tc-99m-mibi scintigraphy as compared with other modalities is discussed.

The aim of the study was to evaluate the clinical usefulness of N-terminal pro-brain natriuretic peptide (NT-Pro BNP) and nitric oxide (NO) with echocardiography (gold standard test) in diagnosis of canine cardiomyopathy. Out of 374 cases, 82 cases showing cardiovascular abnormalities including 16 cases of cardiomyopathy were further selected for standardization of biomarkers. Significant (P

This study shows the usefulness of Artificial Neural Network (ANN) in maintenance planning and man-agement. An ANN model based on the multi-layer perceptron having three hidden layers and four processing elements per layer was built to predict the expected downtime resulting from a breakdown or a maintenance activity. The model achieved an accuracy of over 70% in predicting the expected downtime.
