Preclinical Positron Emission Tomographic Imaging of Acute Hyperoxia Therapy of Chronic Hypoxia during Pregnancy by Alexander Zheleznyak, Joel R. Garbow, Michal Neeman, Suzanne E. Lapi

“…Herein we report first-in-mouse PET imaging of fetuses employing both tracers [ 18 F]FDG (metabolism) and 64 Cu-ATSM (hypoxia). [ 18 F]FDG PET/CT imaging allowed clear visualization of placental-fetal structures and supported quantification of tracer uptake, making this a sensitive tool for monitoring placental function in preclinical rodent models. These measurements illustrate the potentially irreversible damage generated by chronic exposure to hypoxia, which cannot be corrected by acute exposure to hyperoxia.…”

An association rule-based approach for frequent item mining of multi-stage access data by Silong Wu

“…Only one database scan is required, and frequent itemsets are directly generated without generating candidate itemsets, greatly improving the efficiency of the algorithm; Introducing weights into the improved Apriori algorithm and designing a weighted support function, by assigning different weights to different itemsets, more accurately reflects the importance and differences of itemsets in practical applications, thereby improving the accuracy of frequent item mining. …”

Analyse d'une formation plurilingue à distance : actions et interactions by Jean-Jacques Quintin, Monica Masperi

“…Galanet" learning schemes assemble large groups of students (from one to two hundred in general) who are geographically located in different universities and committed to completing common tasks the final objective of which is to create a quadrilingual press file publication online.The present study will be developed along two complementary axes:1. a quantitative analysis of the messages posted on the forum page of the platform for each session.2. a qualitative analysis of sample interventions generated in one of these sessions.On the one hand, the quantitative approach will allow for the highlighting of certain salient features of the e-learning experience as a whole, including how sessions function and their impact on both students and tutors.On the other hand, the qualitative approach will allow to examine and understand more fully the discursive practices elicited by the learning scenario and the plurilinguistic dimension of the forum exchanges.…”

Hardcoded vulnerability detection approach for IoT device firmware by Chao MU, Xin WANG, Ming YANG, Heng ZHANG, Zhenya CHEN, Xiaoming WU

“…With the popularization of IoT devices, more and more valuable data is generated.Analyzing and mining big data based on IoT devices has become a hot topic in the academic and industrial circles in recent years.However, due to the lack of necessary detection and protection methods, many IoT devices have serious information security risks.In particular, device hard-coded information is closely related to system encryption and decryption, identity authentication and other functions, which can provide confidentiality protection for core data.Once this information is exploited by malicious attackers, serious consequences such as sensitive information leakage, backdoor attacks, and unauthorized logins will occur.In response to this problem, a multi-type character recognition and positioning scheme was designed and a hard-coded vulnerability detection method in executable files was proposed based on the study of the characteristics of hard-coded vulnerabilities in IoT devices.The proposed method extracted the firmware of IoT devices and filtered all executable files as the source to be analyzed.Then, a solution to identify and locate three types of hard-coded characters was provided.Further, the reachability of the function, where the hard-coded character was located, was analyzed according to the function call relationship.Meanwhile, the instruction heterogeneity was mitigated by an intermediate representation (IR) model.The character and parameter hard-coded values was obtained through a data flow analysis approach.A symbolic execution method was devised to determine the trigger conditions of the hard-coded vulnerabilities, and then the vulnerability detection result was output.On the one hand, the proposed method introduced the method of symbolic execution based on the use of the intermediate representation model, which eliminated the dependency of instruction architecture and reduces the false positive rate of vulnerabilities; On the other hand, this method can integrate characters, files, and cryptographic implementation to realize the different characteristics of three types of hard-coded characters, which increased the coverage of vulnerability detection and improves the versatility of the detection method.The experimental results show that the proposed method can effectively detect three types of hard-coded vulnerabilities of characters, files and cryptographic implementation in various IoT devices, and has good detection accuracy, which can provide certain guidance for the deployment of subsequent security protection technologies.…”

Mechanical Behavior and Energy Evolution of Sandstone considering Slenderness Ratio Effect by Bibo Dai, Xingdong Zhao, Shuwen Zhang, Qian Kang, Zhonghua Zhu

“…When the slenderness ratio, D, is lower than 1.5, complex failures and multiple shear planes are formed, while simple failures and single shear planes are generated at D larger than 1.5. Besides, the AE ringing counts are more obvious with a higher slenderness ratio, D, at the initial compression stage due to the greater body volume and more defects in the sandstone. …”
