This study aims to examine design students' intention towards using Artificial Intelligence-aided Design Tools (AIDTs). An extended model is developed by combining the affective-cognitive consistency theory with the Unified Theory of Acceptance and Use of Technology (UTAUT). Data are collected through online comments from Chinese streaming media platforms and responses from a survey involving 313 Chinese students, with subsequent analysis using Partial Least Squares and Structure Equation Modeling (PLS-SEM) statistical techniques and Natural Language Processing (NLP). The results reveal that technophobia, perceived enjoyment, performance expectancy, and effort expectancy directly affect the intention of design students to use AIDTs. Additionally, social influence, facilitating conditions, and subjective knowledge indirectly influence this intention. Technophobia, perceived enjoyment, and subjective knowledge emerge as critical determinants. The proposed framework offers insights for AIDTs developers to enhance user experience, while educators are encouraged to provide requisite training and incentives to motivate design student's engagement with AIDTs.

To ensure the safe application of 50% bifenazate water dispersible granule (WDG), field trials were conducted in Guangdong, Guangxi, and Hunan Provinces of china for 2 consecutive years to evaluate the final residue and degradation dynamics of bifenazate in citrus and soil. Bifenazate was analyzed by the optimized quick, easy, cheap, effective, rugged, and safe (QuEChERS) combined with the high-performance liquid chromatography (HPLC) method, which achieved good linearity over the range of 0.01-5.0 mgL-1 with a correlation coefficient r = 0.9999. The average recoveries for bifenazate in citrus and soil were 77.7-105.0%, with relative standard deviations (RSDs) of 3.5-8.7%. The degradation of bifenazate in citrus and soil were consistent with the first-order kinetic equation, the half-lives of bifenazate in citrus and soil were 9.46-27.29 and 3.81-17.24 days, respectively. The final residues of bifenazate in citrus and soil were 0.012-1.582 mgkg-1. On the 21st day after the last application, bifenazate decreased to below the maximum residue limit (MRL) stipulated by china. RQchronic suggested that 50% bifenazate WDG be sprayed once with dosages ranging from 250 to 375 mg a.i.L-1 is safe for humans.

Graphite sheets with pi-pi conjugated structures offer easy processing and scalability for large-scale films, showing excellent phonon transport properties. However, the strong oxidation and nonoxidized state of the graphite sheets are not conducive to fabricating thick graphite films, significantly limiting their potential applications in next-generation flexible electronics. To address this challenge, weakly oxidized wrinkled graphite nanosheets (WGNs) were developed, positioned between strong oxidation and nonoxidation states. The WGNs were further combined with polyamide acid (PAA) via noncovalent functional auxiliary dispersion. During the staged heating process, the defect repair mechanism facilitated by PAA enabled the restoration of the lattice structure of the graphite film (WGNF-C) at a lower temperature (1400 degrees C). As a result, the prepared thick WGNF-C film (98.01 mu m) exhibits excellent in-plane thermal conductivity (471.2 W m-1 K-1), out-plane thermal conductivity (4.5 W m-1 K-1), electrical conductivity (3790.4 S/cm), and electromagnetic interference shielding effectiveness (73.2 dB). Moreover, the film's wrinkled structure also gives it high tensile strength (32.6 MPa) and good flexibility. This bubble-mediated method, featuring controllable oxidation and enhanced by PAA-assisted dispersion and defect repair, provides new insights into the controlled processing of graphite. It also offers a novel design pathway for constructing flexible, high-conductivity thick graphite films.

Silicon heterojunction (SHJ) solar cells have enormous application prospects due to their high efficiency and small carbon footprint. However, during long-term use, the i-a-Si passivation layer of heterojunction (SHJ) solar cells tends to be destroyed by ultraviolet radiation, causing performance degradation. To eliminate this impact, downshifting (DS) materials of YVO4:Eu3+,Bi3+ on the glass surface absorb ultraviolet light and convert it to wavelengths with a higher spectral response of SHJ solar cells. Furthermore, adding anti-reflection (AR) layers on the DS layer's surface will help maintain high transmittance and weather resistance. YVO4:Eu3+,Bi3+ is prepared by using a wet chemical method, with no need for additional manufacturing of phosphors. The DS layer achieves uniform luminescence and expands the excitation spectrum. The average transmittance of glass coated with downshifting and anti-reflection (DSAR) is 96.80%, higher than that of glass with AR only. After high temperature and high humidity tests, the average transmittance of DSAR glass and the short-circuit current density of the module decreased by 1.44% and 0.59 mA cm-2, much lower than that of AR coating (decreased) samples, which decreased by 2.53% and 1.43 mA cm-2. After the UV test, the luminous intensity of the DSAR layer is much higher than that of the DS layer. Therefore, the DSAR layer could offer an easy industrialization approach to improve the outdoor reliability of SHJ solar cells.

The ambiguity and stickiness of text in natural scenarios make text recognition models incorrectly recognize certain characters as others. To address the above problems and the computational scale of the model, we propose a real-time effective text recognition method (IGTR). The method introduces the involution operator in extracting feature sequences within a larger sensory field using a smaller number of parameters. Due to the dependency of the characters before and after the text line, after obtaining the text feature sequence, IGTR uses the gate recurrent unit (GRU) algorithm to obtain richer contextual semantic information and pairs it with the graph convolutional neural network (GCN) to further enhance the semantics of the text features on the basis of the structure of the graph. Finally, the CTC algorithm is used to optimize the computation process of the loss function, and the dynamic planning of the search path is adopted to further reduce the computation amount of the text recognition model. Comparative experiments on ICDAR 2013, ICDAR 2015 and SVT datasets show that the method can effectively recognize multi-scale fuzzy text and sticky text within 75ms.

Groundwater plays a pivotal role in the formation and evolution of landslide disasters. To efficiently and environmentally acquire information about groundwater flow velocity and direction, a novel method is proposed that integrates the equivalent pendulum model with visual measurement technology. This method is based on the principle that a tethered buoyant sphere will experience drag and deviate from its initial position until a state of equilibrium is reached when the viscous fluid flows around the sphere. To measure the offset and the angular deviation of the buoyant sphere, a visual technique is employed. research findings demonstrate a positive correlation between the buoyant sphere's offset and groundwater flow velocity. Measuring the angular deviation of the buoyant sphere determines the current heading. This approach exhibited significant accuracy during experimentation, with the sensor displaying a precision of 5.6% in measuring flow velocity within the range of 0-0.2 mm s-1, and +/- 4.31 degrees in measuring flow direction. Compared to conventional methods, this technique allows for the convenient acquisition of groundwater flow velocity and direction data without the need for auxiliary tracing agents. Furthermore, its measurements remain unaffected by factors such as water quality, temperature, pressure, and salinity within hydrogeological boreholes, or environmental conditions, fulfilling the requirement for real-time monitoring of minimal flow rates and directions in landslide groundwater, rivers, and lakes.

Background In poultry, the smooth transition of follicles from the preovulatory-to-postovulatory phase impacts egg production in hens and can benefit the poultry industry. However, the regulatory mechanism underlying follicular ovulation in avians is a complex biological process that remains *** Critical biochemical events involved in ovulation in domestic chickens(Gallus gallus) were evaluated by transcriptomics, proteomics, and in vitro assays. Comparative transcriptome analyses of the largest preovulatory follicle(F1) and postovulatory follicle(POF1) in continuous laying(CL) and intermittent laying(IL) chickens indicated the greatest difference between CL_F1 and IL_F1, with 950 differentially expressed genes(DEGs), and the smallest difference between CL_POF1 and IL_POF1, with 14 DEGs. Additionally, data-independent acquisition proteomics revealed 252 differentially abundant proteins between CL_F1 and IL_F1. Perivitelline membrane synthesis, steroid biosynthesis, lysosomes, and oxidative phosphorylation were identified as pivotal pathways contributing to ovulation regulation. In particular, the regulation of zona pellucida sperm-binding protein 3, plasminogen activator, cathepsin A, and lactate dehydrogenase A(LDHA) was shown to be essential for ovulation. Furthermore, the inhibition of LDHA decreased cell viability and promoted apoptosis of ovarian follicles in *** This study reveals several important biochemical events involved in the process of ovulation, as well as crucial role of LDHA. These findings improve our understanding of ovulation and its regulatory mechanisms in avian species.

In the electrocatalytic CO2 reduction reaction, the first hydrogenation step only forms *COOH or *HCOO, which often limits the catalytic efficiency. Herein, we have extensively investigated the effect of transition metal atom vacancies in a series of M2B2 (M = Mo, Ti, V, Cr, Fe, Hf) MBenes on the catalytic performance of the CO2RR. Our results suggest that an active microregion formed by the Mo vacancy in Mo2B2 directly facilitates the cleavage of the C-O bond in *CO2 during the first hydrogenation step, leading to the formation of *CO/*OH intermediates, resulting in high selectivity for CH4 production (UL = -0.49 V). The modulation mechanism is illustrated by the vacancy-induced local electronic structure reconstruction, which leads to differences in electron filling of the d orbitals of Mo near the vacancy. This facilitates a unique *CO2 adsorption configuration, in which the orbital is fully occupied, significantly weakening the C-O bond. And due to the lower energy barrier for hydrogenation occurring on the O atom, the first protonation step leads to the cleavage of *CO2, creating a new CO2RR pathway. This phenomenon expands the methods of CO2 activation and CO2RR pathways, paving the way for constructing vacancies as co-catalytic sites to enhance product selectivity.
