Advanced persistent threat (APT) is a serious threat to the Internet. With the aid of APT malware, attackers can remotely control infected machines and steal sensitive information. DNS is popular for malware to locate command and control (C&C) servers. In this paper, we propose a novel system placed at the network egress point that aims to efficiently and(More)
Multiplex PCR was established to detect porcine circovirus type 2 (PCV-2), porcine parvovirus (PPV) and porcine pseudorabies virus (PRV) and applied to samples from 137 piglets exhibiting clinical signs of postweaning multisystemic wasting syndrome (PMWS). PCV-2 DNA was detected from all samples. Moreover, 43 samples were positive for PPV but negative for(More)
During the 2003 Mars Exploration Rover (MER) mission, onboard rover localization has been performed primarily by IMU, wheelodometry, and sun-sensing technologies. In cases where the rover experiences slippage caused by traversing loose soil or steep slopes, particularly in a crater, the onboard visual odometry (VO) technique is applied. A bundle adjustment(More)
Genotypic variations and correlations were estimated for sugar and acid contents on afresh flesh weight basis in peach and nectarine genotypes derived from a clone of a wild peach (Prunus davidiana) by three generations of crosses with commercial nectarine varieties. 107genotypes were studied in Avignon (France), 40 in Gotheron (France), and 18 of them were(More)
Mobile Ad hoc networks (MANETs) are a new paradigm of wireless network, offering unrestricted mobility without any underlying infrastructure such as base station or mobile switching centers. Basically ad hoc network is a collection of nodes communicating with each other by forming a multi-hop network. In a mobile ad hoc network, it is much more vulnerable(More)
In this study, 16 hairpin RNA (hpRNA) vectors were constructed, each harboring 50 bp viral RNA sequence as the stem. They all targeted the coat protein (CP) gene of Potato virus Y (PVY). Virus resistance assay revealed that hairpin constructs targeting the anterior 200 bp regions of the CP gene were unable to induce virus resistance, while the 12 hpRNA(More)
Maternal inheritance of sugars and acids in peach fruit were investigated during two successive years using reciprocal populations derived from ‘low acid’ (LA) flat peach ‘Zaolupan’ and non-LA round peach ‘Zaoxing’. The reciprocal populations segregated into LA round, LA flat, non-LA round and non-LA flat-fruited offspring. Generally, the reciprocal(More)
