Agents partition deterministic outcomes into good or bad. A direct revelation mechanism selects a lottery over outcomes — also interpreted as time-shares. Under such dichotomous preferences, the probability that the lottery outcome be a good one is a canonical utility representation. The utilitarian mechanism averages over all deterministic outcomes “approved” by the largest number of agents. I...

Ordering theory method was used to determine existing hierarchies within a set of items. But the method is restricted to dichotomously scored items. This limitations narrow its application in many empirical data. The purpose of this study is to introduce polytomous ordering theory (POT), developed by Y. H. Lin , W. M. Bart and K. J. Huang, and apply it in the knowledge structure analysis of cap...

BACKGROUND Long axis strain (LAS) has been shown to be a fast assessable parameter representing global left ventricular (LV) longitudinal function in cardiovascular magnetic resonance (CMR). However, the prognostic value of LAS in cardiomyopathies with reduced left ventricular ejection fraction (LVEF) has not been evaluated yet. METHODS AND RESULTS In 146 subjects with non-ischemic dilated ca...

Docking scoring functions can be used to predict the strength of protein-ligand binding. It is widely believed that training a scoring function with low-quality data is detrimental for its predictive performance. Nevertheless, there is a surprising lack of systematic validation experiments in support of this hypothesis. In this study, we investigated to which extent training a scoring function ...

BACKGROUND Reporting the scoring details of continuous outcome measures in randomized trials allows readers to interpret the size of any effect of the intervention. This study aimed to determine, in a sample of randomized trials: 1) the completeness of reporting of scoring details for continuous outcome measures, and 2) whether trial authors comment on the clinical significance of statistically...

Irregular firing of neurons can be modeled as a stochastic process. Here we study the perfect integrate-and-fire neuron driven by dichotomous noise, a Markovian process that jumps between two states (i.e., possesses a non-Gaussian statistics) and exhibits nonvanishing temporal correlations (i.e., represents a colored noise). Specifically, we consider asymmetric dichotomous noise with two differ...

This paper presents a thesis proposal on approaches to automatically scoring non-native speech from second language tests. Current speech scoring systems assess speech by primarily using acoustic features such as fluency and pronunciation; however content features are barely involved. Motivated by this limitation, the study aims to investigate the use of content features in speech scoring syste...

We consider the problem of allocating a set on indivisible items to players with private preferences in an efficient and fair way. focus valuations that have dichotomous marginals, which added value any item is either 0 or 1, aim design truthful allocation mechanisms (without money) maximize welfare are fair. For case submodular we such deterministic mechanism. The output by our mechanism Loren...
