A key function of a host-based intrusion detection system is to monitor program execution. Models constructed using static analysis have the highly desirable feature that they do not produce false alarms; however, may still miss attacks. Prior work has shown trade-off between efficiency and precision. In particular, more accurate models based upon pushdown automata (PDA) are very inefficient operate due non-determinism in stack activity. this paper, we present techniques for determinizing...
The DArk Matter Particle Explorer (DAMPE) is a satellite-borne experiment, in operation since 2015, aimed at studying cosmic rays and high-energy gamma rays. Proton helium are the first- second-most abundant components Given their smaller interaction cross sections with interstellar medium, compared to heavier nuclei, they can travel larger distances, thereby becoming important probes cosmic-ray sources as well acceleration propagation mechanisms. Recently, DAMPE collaboration, machine...
With the rapid development of quantum computing, a variety convolutional neural networks (QCNNs) are proposed.
