党的二十届三中全会强调要提升产业链供应链韧性和健全安全制度,打造自主可控、安全可靠的产业链供应链。在此背景下,研究我国产业链供应链安全发展的逻辑、障碍与路径,可以为实现我国产业链供应链安全发展提供重要的理论基础。产业链供应链安全发展的逻辑,是实现产业链供应链安全需要确保主体要素和结构要素的安全。通过对大宗原料、规模化制造、高新技术、生产性服务四大重点产业的八家典型企业的多案例研究,基于主体要素和结构要素的安全逻辑,识别我国重点产业的产业链供应链安全障碍。进而构建产业链供应链安全发展的路径,包括维护路径和阶跃路径两个维度。维护路径强调从主体要素和结构要素两个视角展开。阶跃路径强调以社会引领、技术驱动、制度辅助为核心要素。为实现维护路径和阶跃路径的有效实施,对于维护路径,需要启动我国重要产业链供应链的韧性战略设计和完善本土产业链供应链安全预警机制;对于阶跃路径,需要通过产业集群和搭建产业信息服务体系支持本土企业深度参与全球产业链供应链重构,通过改革科技创新体制加快突破产业链供应链的关键核心技术,通过构建全国统一大市场推动产业链供应链增加需求活力。

In this study, we investigate the acoustic topological insulator or topological metastructure, where an acoustic wave can exist only in an edge or interface state instead of propagating in bulk. Breaking the structural symmetry enables the opening of the Dirac cone in the band structure and the generation of a new band gap, wherein a topological edge or interface state ***, we systematically analyze two types of topological states that stem from the acoustic valley Hall effect mechanism;one type is confined to the boundary, whereas the other type can be observed at the interface between two topologically different structures. Results denote that the selection of different boundaries along with appropriately designed interfaces provides the acoustic waves in the band gap range with abilities of one-way propagation, dual-channel propagation, immunity from backscattering at sharp corners, and/or transition between propagation at interfaces and boundaries. Furthermore, we show that the acoustic wave propagation paths can be tailored in diverse and arbitrary ways by combing the two aforementioned types of topological states.

Modified adaptive observer based backstepping control system for dynamic positioning of ship is proposed. As an improvement, the adaptive observer takes the first-order wave frequency model and the bias term which represent the slowly varying environmental disturbances and the unmodeled dynamics. Thus, the wave-frequency motions are filtered out, and only the reconstructed low-frequency motions are sent as inputs of the controller. Furthermore, as the ship dynamics parameters are unknown, the adaptive estimation law is designed for both the unknown ship dynamics and the unmeasured state variables. Based on the estimated states and parameters, backstepping controller considering the integral action is designed. Global exponential stability （GES） for the total system is proved using Lyapunov direct method. Simulation results show a good performance of the observer and control system.

The main purpose of this paper is to establish, using the Littlewood–Paley–Stein theory(in particular, the Littlewood–Paley–Stein square functions), a Calderón–Torchinsky type theorem for the following Fourier multipliers on anisotropic Hardy spaces Hp(Rn;A) associated with expensive dilation A:■Our main Theorem is the following: Assume that m(ξ) is a function on Rn satisfying ■with s > ζ--1(1/p-1/2). Then Tm is bounded from Hp(Rn;A) to Hp(Rn;A) for all 0 < p ≤ 1 and ■where A* denotes the transpose of A. Here we have used the notations mj(ξ) = m(A*jξ)φ(ξ) and φ(ξ) is a suitable cut-off function on Rn, and Ws(A*) is an anisotropic Sobolev space associated with expansive dilation A* on Rn.
