A Bioinspired Soft Manipulator Based on Wave Spring Structure: Design and Control

Architectured soft structures have unlocked new possibilities for designing continuum manipulators with tailored mechanical performance. This work introduces a bioinspired soft manipulator based on modular wave spring units, leveraging the high elasticity of wave spring structure...

The Effects and Mechanisms of Thermal Oxygen Aging on Trap Characteristics and Electrical Performance of Functional Group‐Grafted Materials for HVDC Cable Insulation

ABSTRACT In this study, N‐allylaniline (NA), a functional monomer possessing both deep trap‐inducing and antioxidant capabilities, was grafted onto cross‐linked polyethylene (XLPE) to prepare XLPE‐g‐NA. Both XLPE and XLPE‐g‐NA were subjected to thermo‐oxidative aging, and their p...

Composite sliding mode control of a steer-by-wire road-feel motor using spatial-domain iterative learning and an extended state observer

In steer-by-wire systems, delivering accurate and smooth steering feedback is challenging due to periodic torque ripples, friction nonlinearities, and external disturbances. This paper proposes a layered composite control strategy for the steering feel motor, integrating sliding...

In Situ Growth of PDA Layer on PEI Film: Enhanced Dielectric Energy Storage Performance and Its High‐Temperature Limitation

ABSTRACT To improve the insulation and energy‐storage performance of polyetherimide (PEI) films, surface‐modified PEI/polydopamine (PDA) films were fabricated via in situ polymerization of dopamine. This study explores the influence of the PDA layer on the wide‐temperature dielec...

Preparation and Dielectric Properties of Polyethylene Composites Modified by Nano‐ TiO 2 Coated Zeolites With Different Pore Sizes

ABSTRACT Low‐density polyethylene (LDPE) insulation in high‐voltage direct current (HVDC) cables is prone to space charge accumulation and electric field distortion. To address this, we propose a core–shell modification strategy using nano‐TiO 2 ‐coated porous zeolites (4A and Na...

Cloud-aided multi-party private set intersection using Chinese national cryptographic algorithms

Abstract Multi-party private set intersection (MPSI) is a fundamental primitive for privacy-preserving data collaboration, enabling multiple parties to compute the common elements of their private sets without revealing non-intersection elements. Existing MPSI protocols are mainl...

Wear-InducedInterfacial Diffusion in TiN Coatings:A Molecular Dynamics Study

Abstract Understanding the relationship between structural degradation and atomic diffusion is essential for elucidating coating failure at solid interfaces. However, the atomic-scale connection between wear and diffusion remains unclear under coupled thermo-mechanical conditions...

Privacy-preserving spatial keyword query with exclusion keywords and multi-preference support in road networks

Existing spatial keyword query methods mainly focus on the relevance between interest objects and keywords, while paying relatively limited attention to multiple preference scenarios in road network environments. To overcome the limitations of existing methods in addressing spati...

The Bifunctionalityof Tetramethylguanidine Enablesthe Synthesis of Poly Substituted Imidazolinones from Ketones

Abstract A novel strategy for the efficient construction of polysubstituted imidazolinones from simple ketones was developed based on the bifunctional role of tetramethylguanidine (TMG). In this reaction, TMG served simultaneously as an organic base and a structural unit precurso...

Reliability analysis of large area sintered Cu interconnects based on simulation and thermal shock test

Purpose The purpose of this study is to assess the thermomechanical reliability of large-area sintered Cu interconnects for automotive power modules under actual operating conditions and to determine the optimal sintering layer thickness using finite element simulation and experi...

Acid Aging Induced Room‐Temperature Vulcanized Silicone Rubber Flashover Mechanism and Enhancement via Nano‐ TiO 2 Modification

ABSTRACT Room‐temperature vulcanized (RTV) silicone rubber is widely used as external insulation, but long‐term exposure to acidic media degrades its insulating performance and reduces flashover voltage. This study examines RTV's chemical structure, surface properties, and flasho...

IA-3DGS Identity-Anchored Dynamic Gaussian Splatting for Long-Term Facial Detail Preservation

Dynamic 3D Gaussian Splatting (3DGS) enables efficient facial-avatar rendering but may suffer from cumulative geometric drift and degradation of identity-specific details when applied to long monocular sequences. To address this problem, we propose IA-3DGS, an identity-anchored d...

Tuning Carbonate Solvation via Electrolyte Engineering Toward Robust Low-Temperature Lithium Metal Batteries

Abstract Conventional ethylene carbonate (EC)-based electrolytes are dominated by strong Li+-solvent coordination, which leads to sluggish reaction kinetics at low-temperature and severe interfacial side reactions under high-voltage operation. Herein, a ternary electrolyte with w...

Wavelength- and Energy-Dependent Nonlinear Absorption and Transient Absorption in Silver Nanoparticles

Nonlinear absorption (NLA) in silver nanoparticles (Ag NPs) is strongly affected by plasmonic field enhancement. However, its wavelength- and energy-dependent evolution on the red side of the surface plasmon resonance (SPR) band remains insufficiently understood. Here, we systema...

Influence mechanism of hydrogen-bond-modulated electronic density of states on the breakdown properties of PP-g-MA/PVDF composites

In general, the design of polymer dielectrics relies on the classical “band-gap criterion,” according to which a larger electronic band gap ( E g ) is typically associated with a higher breakdown strength ( E bd ). However, in hydrogen-bond-containing polypropylene-graft-maleic a...
