The construction of semantically structured, accurate, and comprehensive knowledge bases remains an important but difficult problem. Acquiring the wealth of human knowledge in a machine-readable format would have invaluable benefits for semantic web services and AI applications in general. In this report I outline a new approach that aims to address this challenge by harnessing the power of soc...

We continue the study of the Newton polytope Pm,n of the product of all maximal minors of an m x n-matrix of indeterminates. The vertices of Pm,n are encoded by coherent matching fields A = (A z) , where z runs over all m-element subsets of columns, and each Az is a bijection z —> [m]. We show that coherent matching fields satisfy some axioms analogous to the basis exchange axiom in the matroid...

the research discussed in this article consists of the process ended to propos a structure for social welfare and security which took more than 11 months in social security research institute. the main topics discussed are as follows: 1- the importance of social security and its relationship to economic growth, social justice, human generosity and national honor. 2- the basis and opportunities ...

the molecular mechanisms of the fact that more than 50% of the individuals with the same genetic make up (e.g. identical twins in schizophrenia) do not show the same psychiatric phenotype remained undefined in psychiatry. this along with the failure to find responsible genes with major effects in psychiatric disorders and lack of consistency of genetic association studies led to the current una...

Software architectures capture the most significant properties and design constraints of software systems. In our research work we intended to propose architecture for a reengineering tool. So, this paper will present a survey of techniques that have been proposed a comprehensive technique for design reengineering tool, here emphasize only how basic steps and architecture (extractor) for compre...

There is little published literature about the outcomes of dental hygiene baccalaureate degree education, particularly in Canada. Since there are various dental hygiene entry-to-practice educational models in Canada, exploring baccalaureate dental hygiene education is becoming an increasingly important subject. The purpose of this study was to explore the personal outcomes and dental hygiene pr...

background: although, nontuberculous mycobacteria can cause disease in different organisms, they usually are not reported in most countries because scientists in general consider them as non-pathogens. but, increasing nontuberculous mycobacteria diseases occurrence has changed this belief. nevertheless, there is no meta-analysis review about prevalence of nontuberculous mycobacteria in iran. me...

Since security and privacy problems in RFID systems have attracted much attention, numerous RFID authentication protocols have been suggested. One of the various design approaches is to use light-weight logics such as bitwise Boolean operations and addition modulo 2 between m-bits words. Because these operations can be implemented in a small chip area, that is the major requirement in RFID prot...
