We explore the natural limit of binomial reducibility in nuclear multifragmentation by constructing excitation functions for intermediate mass fragments (IMF) of a given element Z. The resulting multiplicity distributions for each window of transverse energy are Poissonian. Thermal scaling is observed in the linear Arrhenius plots made from the average multiplicity of each element. “Emission ba...
spinal cord compression due to extramedullary hematopoiesis is a well-described and rare syndrome encountered in several hematological disorders including β-thalassemia. hereby, a 37-year old pregnant woman with intermediate β -thalassemia with paraparesis and lower limb hypoesthesia was presented. mri showed soft tissue masses in both sides of thoracic paraspinal area. histologically, a mixtur...
background: &beta-thalassemia; is the most common monogenic disorder in human. the (ct) polymorphism at -158 upstream region of the &gammag-globin; gene and pharmacological factors such as hydroxyurea have been reported to influence &gamma-globin; gene expression and the severity of clinical symptoms of &beta-thalassemia.; methods: in the present study, 51 &beta-thalassemia; intermediate patie...
In this paper we introduce a two-step Certified Reduced Basis (RB) method. In the first step we construct from an expensive finite element “truth” discretization of dimension N an intermediate RB model of dimension N N . In the second step we construct from this intermediate RB model a derived RB (DRB) model of dimension M ≤ N . The construction of the DRB model is effected at cost O(N) and in ...
Recent years have witnessed a new trend of building ontology-based question answering systems. These systems use semantic web information to produce more precise answers to users’ queries. However, these systems are mostly designed for English. In this paper, we introduce an ontology-based question answering system named KbQAS which, to the best of our knowledge, is the first one made for Vietn...
Visual search for an edge or line element differing in orientation from a background of other edge or line elements can be performed rapidly and effortlessly. In this study, based on psychophysical measurements with ten human observers, threshold values of the angle between a target and background line elements were obtained as functions of background-element orientation, in brief masked displa...
I elements in Drosophila melanogaster are non-long terminal repeat (LTR) retrotransposons of particular interest because high levels of transposition can be induced by appropriate crosses. They use a full-length RNA transposition intermediate as a template for reverse transcription. Detailed molecular characterization of this intermediate is rendered difficult because of the many transcripts pr...
In this paper, we introduce and study a mapping from the collection of all intermediate rings of $C(X)$ to the collection of all realcompactifications of $X$ contained in $beta X$. By establishing the relations between this mapping and its converse, we give a different approach to the main statements of De et. al. Using these, we provide different answers to the four basic questions...
