An Integration Testing Framework and Evaluation Metric for Vulnerability Mining Methods

Software an important way to vulnerability mining is detect whether there are some loopholes existing in the software, and also is an important way to ensure the secu- rity of information systems. With the rapid development of information technology and software industry, most of the software has not been rigorously tested before being put in use, so that the hidden vulnerabilities in software will be exploited by the attackers. Therefore, it is of great significance for us to actively de- tect the software vulnerabilities in the security maintenance of information systems. In this paper, we firstly studied some of the common- ly used vulnerability detection methods and detection tools, and analyzed the advantages and disadvantages of each method in different scenarios. Secondly, we designed a set of eval- uation criteria for different mining methods in the loopholes evaluation. Thirdly, we also proposed and designed an integration testing framework, on which we can test the typical static analysis methods and dynamic mining methods as well as make the comparison, so that we can obtain an intuitive comparative analysis for the experimental results. Final- ly, we reported the experimental analysis to verify the feasibility and effectiveness of the proposed evaluation method and the testingframework, with the results showing that the final test results will serve as a form of guid- ance to aid the selection of the most appropri- ate and effective method or tools in vulnera- bility detection activity.

Sphingolipid inhibitor response gene GhMYB86 controls fiber elongation by regulating microtubule arrangement

Although the cell membrane and cytoskeleton play essential roles in cellular morphogenesis,the interaction between the membrane and cytoskeleton is poorly understood.Cotton fibers are extremely elongated single cells,which makes them an ideal model for studying cell development.Here,we used the sphingolipid biosynthesis inhibitor,fumonisin B1(FB1),and found that it effectively suppressed the myeloblastosis(MYB)transcription factor GhMYB86,thereby negatively affecting fiber elongation.A direct target of GhMYB86 is GhTUB7,which encodes the tubulin protein,the major component of the microtubule cytoskeleton.Interestingly,both the overexpression of GhMYB86 and GhTUB7 caused an ectopic microtubule arrangement at the fiber tips,and then leading to shortened fibers.Moreover,we found that GhMBE2 interacted with GhMYB86 and that FB1 and reactive oxygen species induced its transport into the nucleus,thereby enhancing the promotion of GhTUB7 by GhMYB86.Overall,we established a GhMBE2-GhMYB86-GhTUB7 regulation module for fiber elongation and revealed that membrane sphingolipids affect fiber elongation by altering microtubule arrangement.

Modulating hydrothermal condition to achieve carbon dots-zeolite composites with multicolor afterglow

Responsive luminescence materials with prolonged lifetime and multicolor emission have drawn great attention due to their attractive optical property and potential applications.Herein,two responsive carbon dots(CDs)based composites:CD_(1)@MCM-22P and CD_(2)@ZSM-12 were achieved by a one-step hydrothermal method.By adjusting the hydrothermal condition,CD_(1)@MCM-22P owns temperature-dependent afterglow,while CD_(2)@ZSM-12 is equipped with excitation-dependent room-temperature phosphorescence.The photoluminescence mechanisms of CD1@MCM-22P and CD_(2)@ZSM-12 were investigated and proposed,and the composites were applied in multi-mode anti-counterfeiting.This work provides an insight as well as a feasible method for the development of multi-emissive CDs@zeolite composite.
