Scientific codes are all subject to variation in performance depending on the runtime platform and/or configuration, the output writing API employed, and the file system for output. Since changing the IO routines to match the optimal or desired configuration for a given system can be costly in terms of human time and machine resources, the Adaptable IO(More)
The rapid disruption of tropical forests probably imperils global biodiversity more than any other contemporary phenomenon. With deforestation advancing quickly, protected areas are increasingly becoming final refuges for threatened species and natural ecosystem processes. However, many protected areas in the tropics are themselves vulnerable to human(More)
ADIOS is a state of the art componentization of the IO system that has demonstrated impressive IO performance results on the Cray XT system at ORNL. ADIOS separates the selection and implementation of any particular IO routines from the scientific code offering unprecedented flexibility in the choices for processing and storing data. The API was modelled on(More)
When the orthogonal space-time block code (STBC), or the Alamouti code, is applied in multiple-input multiple-output (MIMO) communication systems, with a simple signal decoupling at the receiver, the optimum reception can be achieved. However, in the military application fields the performance deteriorates significantly in presence of directional(More)

Decision tree is an important method for both induction research and data mining, which is mainly used for model classification and prediction. ID3 algorithm is the most widely used algorithm in the decision tree so far. Through illustrating on the basic ideas of decision tree in data mining, in this paper, the shortcoming of ID3's inclining to choose(More)
The objective of the present study was to investigate whether pretreatment with single low loading dose of tongxinluo (TXL), a traditional Chinese medicine, 1 h before myocardial ischemia could attenuate no-reflow and ischemia-reperfusion injury by regulating endothelial nitric oxide synthase (eNOS) via the PKA pathway. In a 90-min ischemia and 3-h(More)
In collective I/O, MPI processes exchange requests so that the rearranged requests can result in the shortest file system access time. Scheduling the exchange sequence determines the response time of participating processes. Existing implementations that simply follow the increasing order of file offsets do not necessary produce the best performance. To(More)
AIM To optimize formulation methods for loading gemcitabine (GEM), the main drug against pancreatic cancer, into albumin nanoparticles for extended blood circulation and improved efficacy. METHODS GEM was loaded into two sizes of disolvation-crosslinked bovine serum albumin nanoparticles, with a mean diameter of 109.7 nm and 405.6 nm, respectively, by(More)
Recommender systems are vital to the success of online retailers and content providers. One particular challenge in recommender systems is the “cold start” problem. The word “cold” refers to the items that are not yet rated by any user or the users who have not yet rated any items. We propose Elver to recommend and optimize(More)
