Inspired by the molecular mechanics of mussel adhesive formation, a novel water-soluble fluorescent macromolecule (polydopamine–polyethyleneimine (PDA–PEI)) is prepared one-pot copolymerization dopamine (DA) and PEI. In this method, DA polymerized to form PDA, which then coupled with PEI mainly through Michael addition. The fluorescence property PDA–PEI attributed addition on 5,6-dihydroxyindole (DHI) units where can hydrogen bonds oxidative products such as DHI force twist out plane,...

In order to improve the mechanical properties and corrosion resistance of 2A97 aluminum-lithium alloy, this research develops a novel strain heat-treatment technology. Surprisingly, alloy treated by 4% pre-strain 48 h deep cryogenic aging exhibits excellent properties, whose yield strength, tensile elongation are 573.7 MPa, 593.6 14.25%, respectively. Furthermore, samples above process is two times as much traditional T6 aged. This study deeply investigates influence various precipitates in...

This paper proposes a flexible and highly sensitive carbon nanotube buckypaper as sensing layer embedded within composite for cure monitoring applications. The was fabricated with mono-dispersion of multi-wall nanotubes by spray-vacuum filtration method. Six different curing conditions (with maximum heating temperatures 120 °C, 108 95 90 85 °C 75 °C) were designed to characterize analyze the electromechanical response BP sensor structure, results indicated that temperature coefficient...

The goal of this study is to use summary generation and topic modeling identify factors contributing vaccine attitudes for three different brands, with the aim generalizing these across regions.

A new method for reporting host–guest inclusion phenomena using an air-supported liquid crystal system based on cyclodextrins was developed.

Despite the recent progress in deep neural networks (DNNs), it remains challenging to explain predictions made by DNNs. Existing explanation methods for DNNs mainly focus on post-hoc explanations where another explanatory model is employed provide explanations. The fact that can fail reveal actual original reasoning process of raises need build with built-in interpretability. Motivated this, many self-explaining have been proposed generate not only accurate but also clear and intuitive...

Interpreting deep neural networks through examining neurons offers distinct advantages when it comes to exploring the inner workings of Deep Neural Networks. Previous research has indicated that specific within vision possess semantic meaning and play pivotal roles in model performance. Nonetheless, current methods for generating neuron semantics heavily rely on human intervention, which hampers their scalability applicability. To address this limitation, paper proposes a novel post-hoc...

Microstructure evolution of 0·2C–5Mn steel during the intercritical annealing at different temperatures was studied. It found that microstructure gradually evolved from martensite structure into a consisted austenite and ferrite process. The retained volume fraction reached maximum value 36·5 after about 10 min 680°C. also carbides precipitated initial stage dissolved following process for all temperatures; interestingly, fresh found, indicating part newly forming unstable would transform...

A novel and simple technique for the controllable shrinkage of inverted-pyramid silicon (Si) nanopore arrays is reported. The Si with sizes from 60 to 150 nm, made using a combination dry wet etching, were shrunk sub 10 or even closed, direct dry-oxygen oxidation at 900 ° C. process pyramidal induced by was carefully modeled simulated. simulation found be in good agreement experimental data within most time range. Using this method, square an average size 30 rectangular nanopores nanoslits...

Pull-out tests were conducted to investigate the effects of corrosion both longitudinal bars and stirrups on bond slip behaviour reinforced concrete specimens. The main experimental variables include strength (26.7 MPa, 37.7 MPa 45.2 MPa) expected loss (0%, 4%, 8% 12%), with a total 63 specimens fabricated. results show that relative bonding under different strengths gradually decreases increasing loss, but higher is, faster its degradation rate. influence stirrup peak can be ignored, it...

Objective This paper aims to understand vaccine hesitancy in the post-epidemic era by analyzing texts related reviews and public attitudes toward three prominent brands: Sinovac, AstraZeneca, Pfizer, exploring relationship of with prevalence epidemics different regions. Methods We collected 165629 Twitter user comments associated brands. The were labeled based on willingness attitude vaccination. utilize a causality deep learning model, Bert multi-channel convolutional neural network...

Objectives To examine the ocular biometric parameters and predict annual growth rate of physiological axial length (AL) in Chinese preschool children aged 4–6 years old. Methods This retrospective cross-sectional study included 1090 kindergarten students (1090 right eyes) between ages 4 6 from Pinggu Chaoyang District, Beijing. Dioptre values were ascertained following cycloplegic autorefraction. Predicted AL was obtained through application Gaussian process regression model as an...

This study investigated the influence of codoping with Ge and GeO 2 on nonlinear coefficient α breakdown voltage E B TiO –Nb O 5 –SrCO 3 varistor ceramics. Ge–GeO notably changed microstructure ceramics, increased α, decreased . When doping contents Nb SrCO were 0.1 0.2 mol%, respectively, optimum content 0.25 mol% 0.75 exhibited high (11.6), low (13.8 V/mm), grain‐boundary barrier Φ (0.96 eV). These results are superior to previous findings. In addition, , which function as sintering aids,...

Drop bruising is among the most common forms of mechanical damage to fruit during postharvest procedures. To minimize inflicted on apples by free falling harvesting, transportation and preservation processes better understand mechanism this damage, paper investigates area contact pressure distribution a drop bruise when an apple certain weight dropped from specific height onto steel substrate. The characteristics were measured using Prescale® pressure-sensitive film subsequently analyzed...

Template-based surface nanopatterning techniques are highly efficient methods in realizing different nanopatterns, which the fundamental structures of various nanodevices. We demonstrate a template pyramidal silicon nanopore array (PSNA) for direct nanopatterning. Using PSNA templates, deposition experiments platinum (Pt) and gold-palladium (Au-Pd) particles on chromium-coated substrates were performed. Individual Pt nanocubes nanocube arrays with shapes feature sizes as small 82 nm...
