Wreathing, discrete gauging, and non-invertible symmetries by Julius F. Grimminger, William Harding, Noppadol Mekareeya

“…Abstract ’t Hooft anomalies of discrete global symmetries and gaugings thereof have rich mathematical structures and far-reaching physical consequences. We examine each subgroup G, up to automorphisms, of the permutation group S 4 that acts on the four legs of the affine D 4 quiver diagram, which is mirror dual to the 3d N $$ \mathcal{N} $$ = 4 SU(2) gauge theory with four flavours. …”

Comparison of Insertion Characteristics of Prewarmed Igel and I-gel at Room Temperature in Adult Patients Undergoing Elective Surgeries- A Randomized Control Trial by Priyanka Pathak, Mushtaq Wani, Heena Saini

“… Background: I-gel is usually inserted at room temperature, but in certain studies it was found that I-gel may mould to the laryngeal structures faster if pre-warmed. Aim: The present study was conducted to investigate this hypothesis by comparing the airway sealing pressure and leak volume amount between prewarmed Igel devices and those kept at room temperature in paralysed adult patients on Volume Controlled Ventilation mode of ventilator posted for elective surgeries. …”

High-performance directional fuzzing scheme based on deep reinforcement learning by Tian XIAO, Zhihao JIANG, Peng TANG, Zheng HUANG, Jie GUO, Weidong QIU

“…With the continuous growth and advancement of the Internet and information technology, continuous growth and advancement of the Internet and information technology.Nevertheless, these applications’ vulnerabilities pose a severe threat to information security and users’ privacy.Fuzzing was widely used as one of the main tools for automatic vulnerability detection due to its ease of vulnerability recurrence and low false positive errors.It generates test cases randomly and executes the application by optimization in terms of coverage or sample generation to detect deeper program paths.However, the mutation operation in fuzzing is blind and tends to make the generated test cases execute the same program path.Consequently, traditional fuzzing tests have problems such as low efficiency, high randomness of inputs generation and limited pertinence of the program structure.To address these problems, a directional fuzzing based on deep reinforcement learning was proposed, which used deep reinforcement learning networks with information obtained by staking program to guide the selection of the inputs.Besides, it enabled fast approximation and inspection of the program paths that may exist vulnerabilities.The experimental results showed that the proposed approach had better performance than the popular fuzzing tools such as AFL and AFLGO in terms of vulnerability detection and recurrence on the LAVA-M dataset and real applications like LibPNG and Binutils.Therefore, the approach can provide support for further vulnerability mining and security research.…”

Influencing Factors Analysis of Local Environmental Regulation Implementation Behaviors in China: Theoretical Analysis and Empirical Test by Feng Pan, Lin Wang

“…Using dynamic game method, the interaction between local government and pollution discharging enterprises is studied in the process of environmental regulation implementation, implementation behaviors and their influencing factors are analyzed, and empirically tested by Structural Equation Model. The results show that increasing marginal inspection budget and reducing marginal inspection cost can improve the inspection probability of local government; reducing the influence coefficient of enterprise profit on local government utility, increasing the weight coefficient of environmental indicators in the performance appraisal system, and increasing the administrative penalty rate, can improve the probability of levy and penalty on pollution discharging enterprises. …”
