A Brief Review on Mean Field Optimal Control Problem from a Linear Quadratic Perspective

引用

Journal of systems science & Complexity 2025年第01期 390-420页

作者： JIANG Xiushan HO daniel.w.C. ZHANG weihai College of New Energy China University of Petroleum (East China) Department of Mathematics City University of Hong Kong College of Electrical Engineering and Automation Shandong University of Science and Technology

This paper reviews the mean field social(MFs) optimal control problem for multi-agent dynamic systems and the mean-field-type(MFT) optimal control problem for single-agent dynamic systems within the linear quadratic(LQ) framework. For the MFs control problem, this review discusses the existing conclusions on optimization in dynamic systems affected by both additive and multiplicative noises. In exploring MFT optimization, the authors first revisit researches associated with single-player systems constrained by these dynamics. The authors then extend the proposed review to scenarios that include multiple players engaged in Nash games, stackelberg games, and cooperative Pareto games. Finally, the paper concludes by emphasizing future research on intelligent algorithms for mean field optimization, particularly using reinforcement learning method to design strategies for models with unknown parameters.

BACKGROUND: Targeted temperature management(TTM) is a common therapeutic intervention, yet its cost-effectiveness remains uncertain. This study aimed to evaluate the real-world cost-effectiveness of TTM compared with that of conventional care in adult out-of-hospital cardiac arrest(OHCA) survivors using clinical patient-level ***: we conducted a retrospective cohort study at an academic medical center in the UsA to assess the cost-effectiveness of TTM in adult non-traumatic OHCA survivors between 1 January, 2019 and 30 June, 2023. The primary outcome was survival to hospital discharge. Incremental cost-effectiveness ratios(ICERs) were calculated and compared with various decision makers' willingness to pay. Cost-effectiveness acceptability curves were utilized to evaluate the economic attractiveness of TTM. Uncertainty about the incremental cost and effect was explored with a 95% confidence ***: Among 925 non-traumatic OHCA survivors, only 30(3%) received TTM. After adjusting for potential confounders, the TTM group did not demonstrate a significantly lower cost(delta cost-$5,141, 95% confidence interval [95% CI]: $-35,347 to $25,065, P=0.79) and higher survival to hospital discharge(delta effect 6%, 95% CI:-11% to 23%, P=0.41). Additionally, a 95% confidence ellipse indicated uncertainty reflected by evidence that the true value of the ICER could be in any of the quadrants of the cost-effectiveness ***: Although TTM did not demonstrate a clear survival benefit in this study, its potential cost-effectiveness warrants further investigation with larger sample sizes. These findings highlight the need for additional research to optimize TTM use in OHCA care and inform resource allocation decisions.

Linear Forgery Attacks on the Authenticated Encryption Cipher ACORN-Like

引用

Chinese Journal of Electronics 2025年第1期34卷 257-265页

作者： Yunqiang Li ting Cui PLA ssF Information Engineering University

The authenticated encryption stream cipher ACORN is one of the finalists of the Competition for Authenticated Encryption: security, Applicability, and Robustness（CAEsAR） and is intended for lightweight applications. Because of structural weaknesses in the state update function of ACORN, we can introduce a linear function to analyze conditions and differential trails of the state collision and present a linear method to construct forgery messages under the condition that the key and initialization vector are known or the register state at a certain time is known. The attack method is suitable for three versions of ACORN and may be also extended to any ACORN-like,of which the linear feedback shift register（LFsR） can be replaced by other LFsRs and the feedback function can be replaced by other nonlinear functions. For continuous l（l > 293） bits of new input data, we can construct 2l-294forgery messages for any given message of ACORN. Using a standard personal computer, a concrete forgery message can be constructed almost instantly and the required central processing unit time and memory are equivalent to the required resources for solving a system of 293 linear equations over the binary field. These attacks in this paper make that the sender and receiver may easily cheat each other, which is not a desirable property for an ideal cipher and casts some doubt on the necessary authentication security requirements of ACORN.

Coal direct liquefaction technology is a crucial contemporary coal chemical technology for efficient and clean use of coal resources. The development of direct coal liquefaction technology and the promotion of alternative energy sources are important measures to guarantee energy security and economic security. However, several challenges need to be addressed, including low conversion rate, inadequate oil yield, significant coking, demanding reaction conditions, and high energy consumption. Extensive research has been conducted on these issues, but further exploration is required in certain aspects such as pyrolysis of macromolecules during the liquefaction process, hydrogen activation, catalysts' performance and stability, solvent hydrogenation, as well as interactions between free radicals to understand their mechanisms better. This paper presents a comprehensive analysis of the design strategy for efficient catalysts in coal liquefaction, encompassing the mechanism of coal liquefaction, catalyst construction,and enhancement of catalytic conversion efficiency. It serves as a comprehensive guide for further research endeavors. Firstly, it systematically summarizes the conversion mechanism of direct coal liquefaction, provides detailed descriptions of various catalyst design strategies, and especially outlines the catalytic mechanism. Furthermore, it addresses the challenges and prospects associated with constructing efficient catalysts for direct coal liquefaction based on an understanding of their action mechanisms.
