The branching (resp. merging) space functor of a flow is a left Quillen functor. The associated derived functor allows to define the branching (resp. merging) homology of a flow. It is then proved that this homology theory is a dihomotopy invari-ant and that higher dimensional branchings (resp

potential U.S. application of this technique would be at a two-lane entrance ramp where the left lane of the entrance ramp merges with the outside lane of the freeway. With dynamic merge control, either the outside freeway lane or the left lane of the entrance ramp would be closed upstream of the merge

Abstract. Segmentation of the left atrium is vital for pre-operative assessment of its anatomy in radio-frequency catheter ablation surgery, which is commonly used for treating atrial fibrillation. In this paper we present an automatic approach for segmenting the left atrium and its pulmonary veins

are eliminated by a component filtering procedure; Thirdly, the left connected components are merged into several text layers, and a set of appropriate constraints are applied to find the real text layer; finally, the text layer is refined through a post-processing step to generate a binary output. Our

This paper investigates the syntactic properties of ‘why’ in in-situ languages (why-in-situ) and proposes that why-in-situ, unlike other wh-phrases, is initially merged into [Spec,CP] in the overt syntax, whether or not the relevant CP is declarative or interrogative (cf. Lin 1992; Rizzi 1990, 1999

This paper proposes a new processor architecture for handling hard-to-predict branches, the diverge-merge processor (DMP). The goal of this paradigm is to eliminate branch mispredictions due to hard-to-predict dynamic branches by dynamically predicating them without requiring ISA support

Like a magic trick, the end of the Cold War fooled and baffled its audience. It happened in full view of scholars and statesmen, yet it flouted all their expectations and left them wondering how and why. Not only why, but why then. If, by 1988 or so, the rulers of Russia saw no profit in projecting
