background & objective: lichen planus is a mucocutaneous disease which is relatively common and in 30-70% of patients, mucosal lesions can be seen and known as a precancerous lesion but its etiology is not completely understood. desmogleins i and iii are the main desmosomal transmembrane proteins. these proteins have been identified as the autoantigen of the autoimmune disease. the aim of t...

purpose: this study aimed to examine the differences in the co-activation of the rectus femoris (rf) and biceps femoris (bf) using the co-contraction index (ci) in aquatic and land environments during a drop-landing task in active and non-active females. methods: in this casual-comparison study, 10 active and 10 non-active females volunteered to participate. the ci was calculated from recorded ...

background : the measuring serum ferritin level as a sensitive inflammatory biomarker might effectively predict preterm delivery, but the power and the best cut-off point of this biomarker for predicting preterm labor in iranian population has not been substantially identified. our purpose was to determine what concentrations of serum ferritin could identify patients at risk for preterm deliver...

High-Level Abstractions for Low-Level Programming Iavor Sotirov Diatchki Ph.D., OGI School of Science & Engineering at Oregon Health & Science University May 2007 Thesis Advisor: Dr. Mark P. Jones Computers are ubiquitous in modern society. They come in all shapes and sizes: from standard household appliances and personal computers, to safety and security critical applications such as vehicle n...

We force and construct a model in which level by level equivalence between strong compactness and supercompactness holds, along with certain additional “inner model like” properties. In particular, in this model, the class of Mahlo cardinals reflecting stationary sets is the same as the class of weakly compact cardinals, and every regular Jonsson cardinal is weakly compact. On the other hand, w...

ion, in the presence of a number of interacting analysis tools? We believe this to be an important challenge but have not yet made much progress towards solving it. Of course, machines often have trouble answering “why” questions because they usually do not keep track of the reasons that previous decisions were made, and because the correct answer can depend on the frame of mind of a human. We ...

In this paper we prove that testing the cyclic level planarity of a cyclic level graph is a polynomial-time solvable problem. This is achieved by introducing and studying a generalization of this problem, which we call cyclic T -level planarity. Moreover, we show a complexity dichotomy for testing the simultaneous level planarity of a set of level graphs, with respect to both the number of leve...

In this paper we discuss the notion of programming at the knowledge level in the context of distributed AI systems. In particular, we show that although a number of languages defining abstract communication primitives have been proposed in the past few years, knowledge-level programming can only be supported if specific symbol-level requirements are satisfied. To illustrate this problem we form...
