High energy consumption has become a critical problem for supercomputer systems. GPU clusters are becoming an increasingly popular architecture for building supercomputers because of its great improvement in performance. In this paper, we first formulate the tasks mapping problem as a mini-mal energy consumption problem with deadline constraint. Its(More)
BACKGROUND Malaria is a major public health burden in the tropics with the potential to significantly increase in response to climate change. Analyses of data from the recent past can elucidate how short-term variations in weather factors affect malaria transmission. This study explored the impact of climate variability on the transmission of malaria in the(More)
Global surface temperature is predicted to increase by at least 1.5°C by the end of this century. However, the response of soil microbial communities to global warming is still poorly understood, especially in high-elevation grasslands. We therefore conducted an experiment on three types of alpine grasslands on the Qinghai-Tibet Plateau to study the effect(More)
Oxidative stress, mitochondrial dysfunction and neuronal apoptosis are thought to be major contributors of Isoflurane toxicity. However, the underlying mechanisms remain largely to be determined. DJ-1, a protein that is involved in the response to various kinds of stress, has shown its neuroprotective effects. Whether DJ-1 has a neuroprotective effect(More)
By analysis of the basic properties of entanglement swapping of high-dimensional Bell states, a universal and general deterministic secure quantum communication (DSQC) protocol is proposed, in which unitary operation is not required. By making use of the results of high-dimensional Bell measurement, the sender and the receiver can encode and decode the(More)
Two protocols of quantum direct communication with authentication [Phys. Rev. A 73, 042305(2006)], proposed by Lee, Lim and Yang, recently were indicated to be insecure against the authenticator Trentpsilas attacks [Phys. Rev. A 75, 026301(2007)]. In this paper, two novel efficient protocols of quantum direct communication with authentication are presented(More)
Keywords: Information-theoretic clustering K-means KL-divergence Variable Neighborhood Search (VNS) a b s t r a c t Information-theoretic K-means (Info-Kmeans) aims to cluster high-dimensional data, such as images featured by the bag-of-features (BOF) model, using K-means algorithm with KL-divergence as the distance. While research efforts along this line(More)
Owing to the exponential nature of the memory or run-tune complexity, many existing methods can only synthesize 3-qubit circuits, however, (G.W. Yang et al., 2005) can achieve 12 steps for the CNP (controlled-Not gate, NOT gate and Peres gate) library in 4-qubit circuit synthesis with mini-length by using an enhanced bi-directional synthesis approach. We(More)
In this paper, a novel deterministic secure quantum communication scheme with four-qubit W states is proposed. By utilizing four kinds of unitary operations, the two legitimate users can directly transmit the secret messages based on the Bell measurements and some additional classical information. Analysis shows that our scheme has a high capacity as each W(More)
