Background: The aim of this study was to classify the left hemiliver medial sector portal branches on the basis of their site of origin and area that supply. The leading motive for this investigation was to contribute to the modern liver practice, especially to the respective and transplantation ones. Methods: The examined material consisted of 27 portobiliary casts performed by injection-corro...

The paper is devoted to an approach to analytic tableaux for propositional logic, but can be successfully extended to other logics. The distinguishing features of the presented approach are: (i) a precise set-theoretical description of tableau method; (ii) a notion of tableau consequence relation is defined without help of a notion of tableau, in our universe of discourse the basic notion is a ...

The segmental branches of the renal artery vary in number and origin. The 1998, Terminologia Anatomica homologates two branches of the renal artery (anterior, posterior) and five segmental arteries: four from the anterior branch and one from the posterior one. The purpose of this study is to evaluate the renal artery branching pattern, the number and origin of the segmental arteries, as well as...

The pathogenic yeast Candida albicans produces large N-glycans with outer regions containing only mannose residues. The outer region comprises a primary branch with multiple secondary and tertiary branches. Tertiary branches are linked to secondary branches by phosphodiester bridges. In the current model of outer chain elongation in the genetically related yeast Saccharomyces cerevisiae, synthe...

As processor pipelines get deeper and wider and instruction windows get larger, the branch misprediction penalty increases. Predication has been used to reduce the number of branch mispredictions by eliminating hard-to-predict branches. However, with predication, the processor is guaranteed to fetch and possibly execute useless instructions, which sometimes offsets the performance advantage of ...

The afferent and efferent arterial branches of the maxillary rete were investigated in 4 lion (Panthera s. Felis leo) heads preserved in the author's department. The heads were injected with acryl plastic via the common carotid arteries to make corrosion casts of the carotid system, and examined from the standpoint of comparative anatomy. The following afferent arterial branches were observed. ...

in this paper, using generalized {polya} urn models we find the expected value of the size of a branch in recursive $k$-ary trees. we also find the expectation of the number of nodes of a given outdegree in a branch of such trees.

In recent studies, global Hopf branches were investigated for delayed model of HTLV-I infection with delay-independent parameters. It is shown in [8, 9] that when stability switches occur, global Hopf branches tend to be bounded, and different branches can overlap to produce coexistence of stable periodic solutions. In this paper, we investigate global Hopf branches for delayed systems with del...
