The attacks on in-vehicle Controller Area Network (CAN) bus messages severely disrupt normal communication between vehicles. Therefore, researches intrusion detection models for CAN have positive business value vehicle security, and the technology can effectively protect network from unlawful attacks. Previous machine learning-based are unable to identify intrusive abnormal due their inherent shortcomings. Hence, address shortcomings of previous technique, we propose a novel method using...

Rice bacterial leaf blight and streak are two important diseases of rice, which can result in yield loss. Currently, effective antimicrobials for rice still lacking. Thus, to develop highly low-risk bactericides, 31 novel 1,3,4-oxadiazole derivatives containing a cinnamic acid moiety were designed synthesized.
