In the title compound, C17H19N3O·CH3OH, the hydrazone molÂecule exists in a trans geometry with respect to the methylÂidene unit and the dihedral angle between the two substituted benzene rings is 42.6 (2)°. In the crystal, the components are linked through N—H⋯O and O—H⋯O hydrogen bonds, forming [100] chains of alternating hydrazone and methanol molÂecules
Automatic Security Bug Detection with FindSecurityBugs Plugin
The security threats to mobile application are growing explosively. Mobile app flaws and security defects could open doors for hackers to easily attack mobile apps. Secure software development must be addressed earlier in the development lifecycle rather than fixing the security holes after attacking. Early eliminating against possible security vulnerability will help us increase the security of software and mitigate the consequence of damages of data loss caused by potential malicious attacking. In this paper, we present a static security analysis approach with open source FindSecurityBugs plugin for Android StThe security threats to mobile application are growing explosively.

Power loss transition of stable ZnO varistor ceramics: Role of oxygen adsorption on the stability of interface states at the grain boundary
Highly stable ZnO varistor ceramics with steadily decreasing power loss have been put into applications in electrical and electronic systems for overvoltage protections, even with the absence of general understandings on their aging behaviors. In this paper, we investigated their aging nature via conducting comparative direct current (DC) aging experiments both in air and in nitrogen, during which variations of electrical properties and interface properties were measured and analyzed. Notably, continuously increasing power loss with severe electrical degradation was observed for the sample aged in nitrogen. The power loss transition was discovered to be closely related to the consumption of oxygen adsorption at the grain boundary (GB), which could, however, remain constant for the sample aged in air. The interface density of states (DOS) Ni, which is crucial for pinning the potential barrier, was proved to decrease in nitrogen, but keep stable in air. Therefore, it is concluded that the oxygen adsorption at the GB is significant for the stability of interface states, which further correlates to the long-term stability of modern stable ZnO varistor ceramics
Improving Certified Robustness via Statistical Learning with Logical Reasoning
Intensive algorithmic efforts have been made to enable the rapid improvements
of certificated robustness for complex ML models recently. However, current
robustness certification methods are only able to certify under a limited
perturbation radius. Given that existing pure data-driven statistical
approaches have reached a bottleneck, in this paper, we propose to integrate
statistical ML models with knowledge (expressed as logical rules) as a
reasoning component using Markov logic networks (MLN, so as to further improve
the overall certified robustness. This opens new research questions about
certifying the robustness of such a paradigm, especially the reasoning
component (e.g., MLN). As the first step towards understanding these questions,
we first prove that the computational complexity of certifying the robustness
of MLN is #P-hard. Guided by this hardness result, we then derive the first
certified robustness bound for MLN by carefully analyzing different model
regimes. Finally, we conduct extensive experiments on five datasets including
both high-dimensional images and natural language texts, and we show that the
certified robustness with knowledge-based logical reasoning indeed
significantly outperforms that of the state-of-the-art
