background non-alcoholic fatty liver disease (nafld) is the most common form of liver disease in many parts of the world. objectives the aim of the present study was to identify the most important factors influencing nafld using a classification tree (ct) to predict the probability of nafld. patients and methods this cross-sectional study was conducted in kavar, a town in the south of fars prov...

Entanglement measures based on a logarithmic functional form naturally emerge in any attempt to quantify the degree of entanglement in the state of a multipartite quantum system. These measures can be regarded as generalizations of the classical Shannon-Wiener information of a probability distribution into the quantum regime. In the present work we introduce a previously unknown approach to the...

We present a new measure, CNF-tree-width (CNFtw), for bounding the complexity of weighted model counting and related #P-hard problems. CNF-tw dominates known measures such as the dtree width and the treewidth of the CNF primal and incidence graphs. We present a novel approach that utilizes the junction-tree structure in order to decompose the formula. We also characterize a new class of CNFs wh...

In a recent paper [Paths, trees and matchings under disjunctive constraints, Darmann et. al., Discr. Appl. Math., 2011] the authors add to a graph G a set of conflicts, i.e. pairs of edges of G that cannot be both in a subgraph of G. They proved hardness results on the problem of constructing minimum spanning trees and maximum matchings containing no conflicts. A forbidden transition is a parti...

The form of the Apple tree is decided by the organ position of the tree, it affects not ONLY the relationship between the vegetative growth and the fruit production, but also the fruit quality. In this research, the continuous growth for 3 years was gotten with polhemus fastrak, and the apple tree model was built in the POV-ray to simulate the interception of the sunlight. A mathematic model wa...

We present and evaluate the power of a new framework for weighted model counting and inference in graphical models, based on exploiting the topology of the junction tree representing the formula. The proposed approach uses the junction tree topology in order to craft a reduced set of partial assignments that are guaranteed to decompose the formula. We show that taking advantage of the junction ...

The role of decomposition-trees (also known as junction and clique trees) in probabilistic inference is widely known and has been the basis for many well known inference algorithms. Recent approaches have demonstrated that such trees have a “hidden structure”, which enables the characterization of tractable problem instances as well as lead to insights that enable boosting the performance of in...
