Abstract Triboelectric nanogenerators (TENGs), a promising strategy for harvesting distributed low‐quality power sources, face inevitable bottlenecks regarding long‐term abrasion and poor durability. Herein, both issues are addressed by selecting an earthworm‐inspired self‐replenishing bionic film (ERB) as the tribo‐material of sliding‐freestanding TENGs (SF‐TENGs), it consists interconnected 3D porous network structure capable storing releasing lubricant under cyclic mechanical stimuli....
Polarization-independent phase modulators based upon liquid crystals (LCs) with a simple device architecture have long been desired for range of optical applications. Recently, researchers demonstrated novel fabrication procedure using cholesteric LCs as primer achieving low polarization dependence coupled large modulation depth.
Recent experimental realizations of optical Skyrmions through the techniques structured light have opened doors to a completely new way representing data in electromagnetic fields, namely its topology. Apart from potentially enhancing bandwidth systems, intrinsically discrete nature topological number allows naturally interface with digital world. However, investigations into protection various media remain limited date. Here, we rigorously define Skyrmion and establish framework that can be...
Skyrmions are important topologically non-trivial fields characteristic of models spanning scales from the microscopic to cosmological. However, Skyrmion number can only be defined for with specific boundary conditions, limiting its use in broader contexts. Here, we address this issue through a generalized notion derived De Rham cohomology compactly supported forms. This allows definition an entirely new $\coprod_{i=1}^\infty \mathbb{Z}^i$-valued topological that assigns tuple integers...

Our uses Gaussian processes model stiffness distribution active learning direct palpation path robot. The paths are chosen such that they maximize acquisition function provided by algorithm. provides flexibility avoid obstacles robot's path, incorporate uncertainties robot position sensor measurements, include prior information about...
Topologically structured matter, such as metasurfaces and metamaterials, have given rise to impressive photonic functionality, fuelling diverse applications from microscopy holography encryption communication. Presently these solutions are limited by their largely static nature preset hindering that demand dynamic systems with reconfigurable topologies. Here we demonstrate a universal optical modulator implements topologically tuneable matter virtual pixels derived cascading low...
To assess whether the joint application of hybrid iterative reconstruction (HIR) and an adaptive filter (AF) could reduce streak artifacts improve image quality neck-and-shoulder computed tomography (CT).This study included 96 patients with suspicious neck lesions who underwent a routine nonenhanced scan on 64-slice CT scanner. The raw data were reconstructed using four different settings: filtered back projection (FBP), HIR, FBP + AF, HIR AF. Regions interest manually drawn in erector...
Skyrmions are topologically protected quasiparticles, originally studied in condensed-matter systems and recently photonics, with great potential ultra-high-capacity information storage. Despite the recent attention, most optical solutions require complex expensive yet produce limited topologies. Here we demonstrate an extended family of quasiparticles beyond normal skyrmions, which controlled confined photonic gradient-index media, extending to higher-order members such as multiskyrmions...
Resistive random access memory (RRAM) has become one of the representatives next generation nonvolatile because its excellent performance, and data reading function is caused by growth fracture conductive filament (CF) in switch layer. Therefore, study thermal properties materials on mechanism a step that cannot be ignored.

Health-related quality of life (HRQoL) is often measured using EQ-5D-3L by the elicitation methods visual analogue scale (VAS) and time trade-off (TTO). Although many countries have constructed both national VAS TTO value sets, fact that sets produces different values bewilders researchers policymakers. The aim this study to explore certain conditions which could yield similar TTO. A homogeneous sample medical school students was selected 18 hypothetical health states methods. were produced...
Titanium matrix composites (TMCs) have broad application prospects in industrial fields such as aerospace, military and automobile. In this paper, the novel refractory metal-ceramics hybrid-reinforced TMCs, (W+TiC+TiB)/TA15, were successfully fabricated through in-situ synthesis reaction between B4C, W Ti-6.5Al-2Zr-1Mo-1V (TA15) alloy during spark plasma sintering. Then, microstructural characteristics mechanical properties of new TMCs systematically investigated. reinforcements are evenly...
Polarization aberrations, such as diattenuation, can significantly affect the performance of modern polarization imaging systems. adaptive optics (P-AO) provides a means for compensating although an approach to deal with diattenuation is not yet available. In this work, we theoretically investigate potential P-AO-assisted aberrated Stokes vector measurement system. We provide comprehensive theoretical and quantitative analysis properties regarding aberration that be compensated by P-AO...
Learning of preference models from human feedback has been central to recent advances in artificial intelligence. Motivated by this progress, and the cost obtaining high-quality annotations, we study problem data collection for learning models. The key idea our work is generalize optimal designs, a tool computing efficient logging policies, ranked lists. To show generality ideas, both absolute relative on items list. We design algorithms settings analyze them. prove that model estimators...
