In this paper, we propose an efficient and scalable low rank matrix completion algorithm. The key idea is to extend the orthogonal matching pursuit method from vector case case. We further economic version of our algorithm by introducing a novel weight updating rule reduce time storage complexity. Both versions are computationally inexpensive for each iteration find satisfactory results in few iterations. Another advantage proposed that it has only one tunable parameter, which rank. It easy...
Artificial dry adhesives have exhibited great potential in the field of robotics. However, there is still a wide gap between bioinspired and living tissues, especially regarding surface adaptability switching ability attachment/detachment. Here, we propose sensing-triggered stiffness-tunable smart adhesive material, combining functions muscle tissues sensing nerves rather than traditional biomimetic strategy that only focuses on structural geometry. Authorized by real-time perception...
Abstract Automatic and continuous blood pressure monitoring is important for preventing cardiovascular diseases such as hypertension. The evaluation of medication effects the diagnosis clinical hypertension can both benefit from monitoring. current generation wearable monitors frequently encounters limitations with inadequate portability, electrical safety, limited accuracy, precise position alignment. Here, we present an optical fiber sensor-assisted smartwatch A adapter a liquid capsule...
The development of a 3D carbon assembly with combination extraordinary electrochemical and mechanical properties is desirable yet challenging. Herein, an ultralight hyperelastic nanofiber-woven hybrid (NWHCA) fabricated by nanofiber weaving isotropic porous brittle quasi-aerogels. Upon subsequent pyrolysis, metallogel-derived quasi-aerogel hybridization nitrogen/phosphorus co-doping are integrated into the NWHCA. Finite element simulation indicates that lamella-bridge architecture NWHCA...
Abstract Low utilization of solar energy remains a challenge that limits photocatalytic efficiency. To address this issue, work proposes bionic reactor (BSPR) for efficient selective oxidation aromatic alcohols. A biomimetic phototropic hydrogel is prepared by coupling chlorine‐doped polypyrrole (Cl‐PPy) and poly( N ‐isopropyl acrylamide) (PNIPAm) to maximize light‐harvesting efficiency automatically, allowing the BSPR maintain high catalytic levels throughout day. Molecular dynamics...

With the high penetration of wind turbines, many issues need to be addressed in relation load frequency control (LFC) ensure stable operation power grids. The particle swarm optimization-based model predictive (PSO-MPC) approach is presented address this issue context LFC with participation turbines. classical MPC was modified incorporate optimization algorithm for generation regulate system frequency. In addition addressing unpredictability turbine generation, PSO-MPC strategy not only...
This Letter reports the first demonstration of a high-speed three-dimensional (3D) schlieren technique based on combination fiber imaging, Toepler's lens-type schlieren, and computed tomography (CT). The uses single camera, two xenon lamps, series bundles to simultaneously capture images turbulent flames from seven orientations with framerate beyond tens kHz. presented method complements existing advantages being flexible, high speed, low cost. 3D is demonstrated validated premixed flame...
The doping of biocompatible nanomaterials into ultrahigh molecular weight polyethylene (UHMWPE) to improve the biocompatibility and reduce wear debris is great significance prolonging implantation time UHMWPE as bearing material for artificial joints. This study shows that can form a composite with nanocrystalline cellulose (NCC, hydrophilic nanosized high aspect ratio) by ball-milling hot-pressing. Compared pure UHMWPE, NCC/UHMWPE exhibits improved tribological characteristics reduced...
The fracture of core-shell particle reinforced composites was simulated using a crack phase field method. A pre-existing may grow along the interface between core and shell (core debonding), penetrate (trans-core fracture), or in matrix (brittle matrix). Shell behaviours resulting from competition resistance driving force are crucial to growth mechanisms. It found that moderate strength low modulus favoured trans-core fracture, high debonding. effects on overall mechanical properties were...
