چکیده

A new approach to tractable deduction from an expressive knowledge base is presented that approximates formulae by automatically mapping them to some restricted language. Various mappings and their properties are discussed, and an anytime algorithm to compute approximations is presented. Several published approaches prove to be special instances of ours. To illustrate this, our formalism is used to formalize hierarchical knowledge bases, and to extend them by allowing negation and mutual exclusion. We believe this to be the rst comprehensive theoretical framework for approximate reasoning.

Growth Performance, Meat Yield, and Economic Responses of Broilers Provided Diets Varying in Amino Acid Density from Thirty-Six to Fifty-Nine Days of Age

Providing broilers diets formulated to a high amino acid density early in life improves subsequent growth performance and meat yield. Diets formulated to high amino acid concentrations beyond 5 wk of age may increase breast meat yield but may not be economically justified. This study examined growth, meat yield, and economic responses of broilers provided diets varying in amino acid density fro...

Weak Solution of a Continuum Model For Vicinal Surface in The Attachment-Detachment-Limited Regime

We study in this work a continuum model derived from 1D attachment-detachmentlimited (ADL) type step flow on vicinal surface, ut = −u 2(u3)hhhh, where u, considered as a function of step height h, is the step slope of the surface. We formulate a notion of weak solution to this continuum model and prove the existence of a global weak solution, which is positive almost everywhere. We also study t...

Diffusion Tensor Tractography in Two Cases of Kernohan-Woltman Notch Phenomenon

Kernohan-Woltman notch phenomenon (KWP) is an ipsilateral motor weakness due to compression of the contralateral cerebral peduncle. We report two cases of KWP following traumatic brain injury. In case 1, ipsilateral hemiplegia was noted after right subdural hemorrhage. Although magnetic resonance imaging showed no abnormal signal changes on cerebral peduncle, diffusion tensor tractography (DTT)...

Disordered Patterns in Clustered Protein Data Bank and in Eukaryotic and Bacterial Proteomes

We have constructed the clustered Protein Data Bank and obtained clusters of chains of different identity inside each cluster, http://bioinfo.protres.ru/st_pdb/. We have compiled the largest database of disordered patterns (141) from the clustered PDB where identity between chains inside of a cluster is larger or equal to 75% (version of 28 June 2010) by using simple rules of selection. The res...
