We prove that every C 1 diffeomorphism away from homoclinic tangencies is entropy expansive, with locally uniform expansivity constant. Consequently, such diffeomorphisms satisfy Shub's entropy conjecture: the entropy is bounded from below by the spectral radius in homology. Moreover , they admit principal symbolic extensions, and the topological entropy(More)
High mobility group protein A2 (HMGA2) is an architectural transcription factor that plays an important role in development and progression of malignant neoplasias. Recently, some studies reported that HMGA2 is also implicated in epithelial–mesenchymal transitions (EMT) and cancer stem cells. But the underlying mechanisms of these conditions are poorly(More)
Several examples on Pd-catalysed carbonylation of methyl C(sp(3))-H bonds with gaseous CO via Pd(II)/Pd(0) catalysis have been reported. However, methylene C(sp(3))-H carbonylation remains a great challenge, largely due to the lack of reactivity of C-H bonds and the difficulty in CO migratory insertion. Herein, we report the stereoselective(More)
—In this paper, a contrastive evaluation of massively parallel implementations of suffix tree and suffix array to accelerate genome sequence matching are proposed based on Intel Core i7 3770K quad-core and NVIDIA GeForce GTX680 GPU. Besides suffix array only held approximately 20%∼30% of the space relative to suffix tree, the coalesced binary search and(More)
This paper provides an overview and information useful for reconstructing bidirectional sieve for hybrid parallelization based on SMP Cluster, which is the individual computational units joined together by the communication network, are usually shared-memory system with one or more multicore processor. The main emphasis is placed on the problem of(More)
In this paper, we focus on the need for two approaches to optimize producer and consumer synchronization for auto-parallelizing compiler. Emphasis is placed on the construction of a criterion model by which the compiler reduce the number of synchronization operations needed to synchronize the dependence in a loop and perform optimization reduces the(More)
In this computer era of rapid development, software development can be seen everywhere, but a lot of softwares are dead in modern development of software. Just as The Mythical Man-Month said, it exists a problem in the software development, and the problem is interflow. A lock of interflow can be said great calamity. Clustering is a environment to breed new(More)
