In this paper we focus on the sensor scheduling for dynamic state estimation among multiple processes. Multiple sensors transmit their measurements to the remote estimator via a shared wireless channel. Only a subset of sensors are allowed to transmit at each time. The objective of the scheduler is to maximize a linear combination of the terminal time estimation error covariances in a log-determinant sense. We develop conditions under which the objective is monotone and submodular. A submodularity-based greedy scheduling algorithm is proposed, and its performance bound is provided. Numerical examples are presented to illustrate the theoretical findings.

Potassium dihydrogen phosphate (KDP) is a key material for inertial confinement fusion and nonlinear optic devices. However, KDP is soft-brittle, deliquescent and temperature-sensitive, making it become a difficult-to-process crystal. Even that, high-performance devices of KDP strictly require atomic-level surfaces, rising a challenge for ultra-precision machining. Due to the nature of deliquescence of KDP, traditional polishing methods are disabled to machine it. As a result, it is significant to summarize advanced polishing methods to achieving atomic-level surfaces of KDP. This review presents the fluid jet polishing, deliquescent polishing and chemical mechanical polishing (CMP) for KDP. It indicates that CMP with rare earth could obtain atomic-level surfaces and the lowest subsurface damages. Finally, future polishing directions on KDP are proposed and discussed. © 2024 Elsevier Ltd

Dynamic scene reconstruction for autonomous driving enables vehicles to perceive and interpret complex scene changes more precisely. Dynamic Neural Radiance Fields (NeRFs) have recently shown promising capability in scene modeling. However, many existing methods rely heavily on accurate poses inputs and multi-sensor data, leading to increased system complexity. To address this, we propose FreeDriveRF, which reconstructs dynamic driving scenes using only sequential RGB images without requiring poses inputs. We innovatively decouple dynamic and static parts at the early sampling level using semantic supervision, mitigating image blurring and artifacts. To overcome the challenges posed by object motion and occlusion in monocular camera, we introduce a warped ray-guided dynamic object rendering consistency loss, utilizing optical flow to better constrain the dynamic modeling process. Additionally, we incorporate estimated dynamic flow to constrain the pose optimization process, improving the stability and accuracy of unbounded scene reconstruction. Extensive experiments conducted on the KITTI and Waymo datasets demonstrate the superior performance of our method in dynamic scene modeling for autonomous driving. Our implementation will be available at https://***/IRMVLab/FreeDriveRF. Copyright © 2025, The Authors. All rights reserved.

Serious climate changes and energy-related environmental problems are currently critical issues in the world. In order to reduce carbon emissions and save our environment, renewable energy harvesting technologies will serve as a key solution in the near future. Among them, triboelectric nanogenerators (TENGs), which is one of the most promising mechanical energy harvesters by means of contact electrification phenomenon, are explosively developing due to abundant wasting mechanical energy sources and a number of superior advantages in a wide availability and selection of materials, relatively simple device configurations, and low-cost processing. Significant experimental and theoretical efforts have been achieved toward understanding fundamental behaviors and a wide range of demonstrations since its report in 2012. As a result, considerable technological advancement has been exhibited and it advances the timeline of achievement in the proposed roadmap. Now, the technology has reached the stage of prototype development with verification of performance beyond the lab scale environment toward its commercialization. In this review, distinguished authors in the world worked together to summarize the state of the art in theory, materials, devices, systems, circuits, and applications in TENG fields. The great research achievements of researchers in this field around the world over the past decade are expected to play a major role in coming to fruition of unexpectedly accelerated technological advances over the next decade. © 2023 The Authors.

ST-Booster: An Iterative SpatioTemporal Perception Booster for Vision-and-Language Navigation in Continuous Environments

arXiv 2025年

作者： Yue, Lu Zhou, Dongliang Xie, Liang Yin, Erwei Zhang, Feitian Department of Advanced Manufacturing and Robotics the State Key Laboratory of Turbulence and Complex Systems College of Engineering Peking University Beijing100871 China Defense Innovation Institute Academy of Military Sciences Beijing100071 China Tianjin Artificial Intelligence Innovation Center Tianjin300450 China Department of Computer Science Harbin Institute of Technology Shenzhen Xili University Town Shenzhen518055 China

Vision-and-Language Navigation in Continuous Environments (VLN-CE) requires agents to navigate unknown, continuous spaces based on natural language instructions. Compared to discrete settings, VLN-CE poses two core perception challenges. First, the absence of predefined observation points leads to heterogeneous visual memories and weakened global spatial correlations. Second, cumulative reconstruction errors in three-dimensional scenes introduce structural noise, impairing local feature perception. To address these challenges, this paper proposes ST-Booster, an iterative spatiotemporal booster that enhances navigation performance through multi-granularity perception and instruction-aware reasoning. ST-Booster consists of three key modules — Hierarchical SpatioTemporal Encoding (HSTE), Multi-Granularity Aligned Fusion (MGAF), and Value-Guided Waypoint Generation (VGWG). HSTE encodes long-term global memory using topological graphs and captures short-term local details via grid maps. MGAF aligns these dual-map representations with instructions through geometry-aware knowledge fusion. The resulting representations are iteratively refined through pretraining tasks. During reasoning, VGWG generates Guided Attention Heatmaps (GAHs) to explicitly model environment-instruction relevance and optimize waypoint selection. Extensive comparative experiments and performance analyses are conducted, demonstrating that ST-Booster outperforms existing state-of-the-art methods, particularly in complex, disturbance-prone environments.

Engineering of interfacial thermal transport is crucial for efficient heat-to-electricity conversion and cooling of electronic devices. Here, we achieve remarkably high interfacial thermal conductance in a series of aluminum/silicon heterostructures grown by molecular beam epitaxy, up to 0.49 GW m−2 K−1 at room temperature, which is ∼29% greater than state-of-the-art values. The pristine interface is near perfect without any notable defects, as confirmed by atomic-resolution transmission electron microscopy. Density functional theory calculations reveal the possible covalent bonding between Al and Si at the interface. Intriguingly, by inserting a monolayer of hydrogen atoms at the interface, the conductance can be reduced by ∼47%. Molecular dynamics simulations show that phonon transmission is primarily suppressed within the frequency range from 2 to 7 THz. Our work highlights the potential of manipulating interfacial thermal transport at the atomic scale and may facilitate diverse applications in thermal management and energy harvesting. © 2025 Author(s).

Cloud manufacturing (CMfg), integrating distributed manufacturing resources as services to cloud center, aims at intelligent, green, and economic customized manufacturing. The optimal composition of services to fulfill particular manufacturing requirement is a core issue to realize efficient cloud manufacturing. Many researchers have studied the problem considering the Quality-of-Service (QoS) of independent services. However, the correlation between services is rarely considered. In this paper, the importance of service correlation is emphasized. Two kinds of service correlation, service exclusion and service collaboration, are modeled for service composition. An improved algorithm DET, which combines Differential Evolution Algorithm (DE) with a Tabu table based on service exclusive and collaborative relationships, is designed to filter composable services and find better solutions for complex tasks. Experiments have shown the effects of service correlation on the quality of composed services and demonstrated the effectiveness of the proposed method DET compared with traditional DE. © 2019 Dime Universita di Genova, DIMEG University of Calabria.

Dynamic modeling and analysis for lateral-torsional coupling vibration of a bolted joint rotor system during speed-up process

Communications in Nonlinear Science and Numerical Simulation 2025年 150卷

作者： Yuqi Li Bo Yang Chuanmei Wen Zhong Luo Bing Li School of Mechanical and Automotive Engineering Guangxi University of Science and Technology Liuzhou 545006 PR China Guangxi Key Laboratory of Automobile Components and Vehicle Technology Liuzhou 545006 PR China Engineering Research Center of Advanced Design and Manufacturing Technology of Heavy Vehicle Components Ministry of Education Guangxi University of Science and Technology Liuzhou 545006 PR China School of Electronic Engineering Guangxi University of Science and Technology Liuzhou 545006 PR China School of Mechanical Engineering & Automation Northeastern University Shenyang 110819 PR China

The time-varying contact states at the contact interface introduced local nonlinear mechanical behaviors of the bolted joint rotor, especially under varying speed condition. In this study, a lateral-torsional coupled dynamic model of a bolted joint rotor system is established using the lumped mass method, and the Iwan model is employed to characterize the interface contact behavior. The influence of contact mechanics on the dynamic characteristics of the rotor system is investigated under both steady-state and speed-up conditions. The results show that lateral contact leads to the appearance of lateral self-excited vibration frequencies in the lateral waterfall diagrams, as well as combined frequencies related to lateral self-excited vibrations in the torsional waterfall diagrams. Furthermore, acceleration introduces additional unbalanced forces, which enhance lateral-torsional coupling, while lower acceleration intensifies stiffness softening and reduces the critical speed. Finally, the simulation results are validated through experiments conducted on a bolted joint rotor test rig. This study proposes a lateral-torsional coupled dynamic model for bolted joint rotors considering interface contact, providing theoretical guidance for the dynamic design and analysis of such rotating machinery.
