Non-radiative recombination caused by defects at grain boundaries hinders the improvement of the performance of perovskite solar cells (PSCs). In this study, a bifunctional onium salt namely Pyridinium p-toluene sulfonate was added to the perovskite precursor solution. The defects of perovskite are passivated and the non-radiative recombination losses are reduced due to the sulfonic acid groups in PPTS molecules interact with Pb²⁺ and pyridine interact with I^-. It also regulates the crystallization of perovskite films, which increases the grain size and improves the crystallinity. The open circuit voltage (V_OC) of the PPTS-modified PSCs is increased from 1.03V to 1.07V, and the fill factor (FF) is increased from 75% to 78%. The resulting power conversion efficiency (PCE) of the solar cell is increased from 19.41% to 21.5%.

Uniconazole, as a broad-spectrum and efficient plant growth regulator, is easily hindered in soil transport, resulting in most drugs not being able to diffuse to plant roots and reducing their utilization efficiency. Based on the above problems, in this paper, peanut oil was used as the oil phase to prepare uniconazole oil in water emulsion. By constructing a transverse transport model soil column, the transverse transport capacity of the peanut oil-based uniconazole lotion in the soil column was investigated in terms of the dispersion mode of the lotion, the type of emulsifier, the concentration of the lotion, the flow rate of the lotion, and the transverse transport distance. Compared with the water dispersion formulation of uniconazole, the uniconazole lotion has a stronger transverse transport capacity than the water dispersant. When the concentration of uniconazole lotion is 500 mg·L^-1, the flow rate into the soil column is 1.23 mL·min^-1, and the transverse transmission distance is 40 cm, it has good transverse transmission capacity. The research results of this article provide a reference for the green and efficient use of uniconazole.

In response to the issues of significant nutrient loss and blockage susceptibility in conventional forage harvesters during the process of chopping rapeseed,this paper presented the design of a chopping and anti-blocking system suitable for rapeseed forage harvesting.To explore the effects of various parameters of the chopping and anti-blocking system on anti-blockage performance and chopping performance,this study utilized the maximum velocity at accumulation point and the number of particles at accumulation point as anti-blockage performance indicators.An orthogonal rotation center combination experiment was conducted,considering the factors of side scraper plate angle and rotational speed.Furthermore,for the chopping performance indicators including the length qualification rate,chopping uniformity,and power consumption,response surface experiments are conducted with main shaft speed and feed rate as experimental factors.Experimental results demonstrate that the factors influencing the velocity at accumulation point,in descending order of significance,are the side scraper plate angle and the main shaft speed.The factors influencing the number of particles at accumulation point,in descending order of significance,are the main shaft speed and the side scraper plate angle.By selecting the minimum values of the maximum velocity at accumulation point and the number of particles at accumulation point as optimization objectives,the optimal combination of parameters for anti-blockage performance was obtained: side scraper plate angle of 11.9° and main shaft speed of 559 r/min,resulting in a particle velocity at accumulation point of 13.6 m/s and 13 particles at accumulation point.Regarding the effects on the length qualification rate,chopping uniformity,and power consumption,the factors in descending order of significance are the main shaft speed and the feed rate.By selecting the maximum values of the length qualification rate and chopping uniformity,and the minimum value of power consumption as optimization objectives,the optimal combination of parameters for chopping performance is determined as main shaft speed of 612 r/min and feed rate of 2 kg,resulting in a length qualification rate of 87.6%,chopping uniformity of 87.2%,and power consumption of 1.0 kJ.The above research and its results can serve as a references for the development of subsequent rapeseed forage choppers.

In order to address the issue of inaccurate positioning caused by the small dispersion distance and mutual shielding after the red flower ball is gathered together during the picking process of the safflower picking robot’s end effector,a method for simultaneous evacuation separation of fruit balls during the feeding stage of safflower plants was proposed.A mechanism for separating red flower balls during feeding was designed,with careful consideration given to its main structure,structural parameters,and kinematic analysis.The analysis reveals that there are no sudden changes in speed or acceleration throughout the entire movement,ensuring stable and reliable motion that meets design requirements.A test bed was constructed to evaluate the performance of fruit ball separation during feeding.Results showed a separation rate of 92.33%,a shielding rate of 3.15% for fruit balls,and damage rates of 0.64% for plants and 1.05% for fruit balls respectively.The separation mechanism effectively increases spacing between adjacent red fruits and fruit balls after clamping operations,resulting in a planar arrangement that reduces picking difficulty.This research provides a theoretical basis for mechanized safflower picking.

based on the field survey in the past four years, the floristic characteristics of urban and rural monocotyledonous weeds in southern Junggar Basin were studied.

A total of 51 genera and 104 species of single genus and minor genus were dominant, and only 1 genus was multiple genera. Life types were mainly perennial herbs (76.58%), and ecotypes were mainly mesophytic (77.48%). There are 7 distribution types and 5 variations in geographical composition, among which temperate zone and its variations contain 21 genera, accounting for the highest proportion. There were 104 species of native weeds, 4 species of exotic invasive weeds, no quarantine weeds, and 3 species of malignant and serious weeds that needed to be monitored and controlled.

WD40 protein is mainly involved in the regulation of biological processes such as the growth and development of plant, synthesis of secondary metabolites and stress responses. WD40, as one of the MYB-bHLH-WD40 (MBW) protein complexes, activates the transcription of genes which are located downstream of synthesis to promote anthocyanin accumulation. Exploring the function of WD40 gene family is the key procedure to analyze the metabolic regulation mechanism of flavonoid secondary metabolites. In this study, based on the pigeon pea (Cajanus cajan) genome, the members of CcWD40 family genes were identified in pigeon pea, and the CcWD40 genes and its responses of Methyl Jasmonate were analyzed by bioinformatics and experiments respectively. With bioinformatics, 116 members of the CcWD40 gene family were identified in the genome of pigeon pea, and the characteristics of the gene structure, chromosome distribution, cis-acting elements of the promoters, and the evolutionary history of the candidate genes were systematically and comprehensively evaluated, and the expression pattern disposed by Methyl Jasmonate was analyzed. The results showed that the amino acid residues of WD40 proteins ranged from 296 to 1 709, and the isoelectric point range was from 4.33 to 9.58; 68 of the 116 genes could be mapped, and these 68 CcWD40 genes were unevenly distributed on 11 chromosomes, mostly located on chromosome 3; the phylogenetic tree divides the members of the pigeon pea CcWD40 family into 18 subfamilies. Although the introns of the CcWD40 gene structure differ greatly, they are relatively similar in the same branch of the evolutionary tree; collinearity analysis shows pigeon pea is the closest relative to soybean among these 3 model organisms; pigeon pea CcWD40 has multiple response elements, including stress response elements, developmental response elements and hormone response elements, such as abscisic acid response element (ABRE),salicylicacid response element (TCA-Element), gibberellin response element (GARE-Motif), etc. It can be seen that their expression is controlled by a complex regulatory network which may play an important role in abiotic stress; it is supposed that based on RNA-seq data analysis, the pigeon pea CcWD40 family genes significantly responded to the disposal of Methyl Jasmonate, in which 96 CcWD40 genes will express less while 20 ones express more and the CcWD40 genes located at the same branch of evolution share the similar responsive tendency. This study will provide important genetic resources and theoretical basis for further exploring the function of WD40 gene in regulating the synthesis of flavonoids and responding to abiotic stress.

There are many types of poisonous weeds in the grasslands of the Tenth Division, with a wide distribution and serious harm. Therefore, investigating and understanding their distribution are of great significance for the prevention and control of poisonous weeds.

The physical properties,particle gradation characteristics,apparent morphology,elemental and mineral composition,and chemical properties of desert sand(DS) in typical desert areas were thoroughly tested,and the key application technologies of DS as concrete fine aggregate were analyzed and studied in order to explore the performance differences of DS from different sources and its influence on concrete.According to the findings,the surface of DS is smooth,the particle size distribution range is constrained,the particles are also fine,and the fineness modulus is primarily between 0.5 and 1.0.The water absorption,mud content and mineral composition of DS have strong regional characteristics,but the voidage ratio is generally larger,more than 44%.The specific surface area and particle size of desert sand will affect the formation process of concrete strength.The presence of sulfides and sulfates in fine DS will increase the strength of concrete.When the mixed sand fineness modulus is the same,the water absorption rate of DS is the main factor affecting the concrete strength.

Composite beam with corrugated steel webs are widely used because of their excellent properties.Although the research on deflection calculation of composite beam with corrugated steel webs which is one of the focuses of its research in China has made great progress in recent years,but only statically determinate structures are considered,and the widely use of statically indeterminate structures with fixed ends in bridge engineering.In order to discuss the deflection of fixed composite beam with corrugated steel webs and provide theoretical basis and guidance for follow-up study,this paper assumes that joint stiffness is large enough,the composite beam with corrugated steel webs will be simplified as two fixed ends or one end fixed and the other hinged,considering the influence of slip and web shear deformation,the corresponding formula of midspan deflection is derived.It is hoped that the deflection calculation method suitable for the actual bridge type will be found step by step.Based on test beam and finite element model,the formula in this paper is verified.The results show that:the proportion of additional slip deflection of composite beams with corrugated steel webs fixed at the ends varies linearly with shear stiffness,which is significantly different from that of parabolic pattern of beams with simply supported ends.The asymmetrical support magnifies the shear deformation and slip effect of composite beams with corrugated steel webs.

Objective Different ototoxic drugs were used to establish the model of sensorineural deafness in Mongolian gerbils, and the three models were compared to provide accurate animal models for the study of sensorineural deafness. Methods Mongolian gerbils model of sensorineural deafness was established by kanamycin sulfate and furosemide (KM+Fur), neomycin (Neo) and Ouabain (Oua), ABR auditory function and cochlear tissue morphological test were examined to compare and analyze the damage characteristics of different ototoxic drugs. Results After KM+Fur modeling, compared with the control group (14.00±1.80), the hearing threshold of Mongolian gerbils in this group (71.00±5.26) was significantly increased, and the cochlear HCs, while SGNs were not significantly damaged. After Neo modeling, 40 mmol·L^-1 Neo only affected the hearing threshold (60.00±8.66) at high frequency 32 kHz, and had no obvious histological changes. n the 100 mmol·L^-1 Neo group, the hearing thresholds of all frequencies were significantly increased, and the cochlear HCs and SGNs were severely damaged. After the modeling of Oua, 1 mmol·L^-1 Oua and 10 mmol·L^-1 Oua could significantly increase the hearing thresholds of all frequencies in gerbils, but the damage ranges were different. 10 mmol·L^-1 Oua severely damaged HCs and SGNs, while 1 mmol·L^-1 Oua only damaged cochlear SGNs. Conclusion KM+Fur can be used to establish sensorineural deafness model with specific damage of HCs in gerbils. 40 mmol·L^-1 Neo can establish sensorineural deafness model with high frequency hearing impairment. Using 100 mmol·L^-1 Neo and 10 mmol·L^-1 Oua, the sensorineural hearing loss model of gerbils with impaired hair cells and spiral ganglion neurons was established. Deafness model with cochlear spiral ganglion neurons specific impairment of gerbils cochlea with 1 mmol·L^-1 Oua was established

Objective The cortex is one of the most sensitive tissues in response to cerebral hypoxia-ischemia. Based on the previous deep sequencing technology, we screened and obtained cortical target genes miR-181a and Bcl-2 that closely respond to cerebral hypoxia ischemia stress. The aim of this study is to verify the above targeted relationships and functions in SH-SY5Y cell line induced by the oxygen-glucose deprivation/reperfusion (OGD/R), and to clarify the role of miR-181a-Bcl-2 regulatory network in OGD/R induced nerve cell apoptosis. Methods The model of hypoxic-ischemic and reperfusion injury in rats was established by suture method, and the model was evaluated by TTC staining and behavioral score. Target gene expression was verified by qRT-PCR and Western Blot. Bioinformatics was used to analyze the target binding sites of miR-181a and Bcl-2 and compare the conservation of the binding sites. The specificity of targeted binding between miR-181a and Bcl-2 was confirmed through dual-luciferase reporter gene experiments. The OGD/R model was used to simulate cerebral ischemia-reperfusion injury in vitro. Cell apoptosis was detected by apoptosis-related protein expression and Hoechst fluorescence staining. Results The expression of miR-181a and Bcl-2 was reversed after middle cerebral artery occlusion in rats. RNA hybird software predicted that miR-181a could bind to the 3'-UTR region of Bcl-2 mRNA, and the nucleotides in the binding region were highly conserved. Dual luciferase reporter gene assay showed that compared with the Bcl-2 3'UTR-WT and mimic-NC co-transfection group, the fluorescence activity of Bcl-2 3'-UTR and miR-181a mimic co-transfection group was lower (P<0.001). There was no significant difference in the fluorescence activity of Bcl-2-Mut co-transfected with miR-181a mimic group (P>0.05). After the OGD/R model was constructed, SH-SY5Y cells were transfected with miR-181a mimics and inhibitors, respectively. It was found that miR-181a could inhibit the expression levels of Bcl-2 mRNA and protein (P<0.001). Overexpression of miR-181a significantly increased the apoptosis of SH-SY5Y cells (P<0.001), while inhibition of miR-181a expression significantly decreased the apoptosis of SH-SY5Y cells (P<0.001). Conclusion miR-181a can target Bcl-2 and down-regulation of miR-181a can inhibit the OGD/R injury induced apoptosis of SH-SY5Y nerve cells by up-regulating the expression of Bcl-2.

Objective By studying the operating efficiency of Xinjiang's medical and health service system, the problems existing in the allocation of medical resources, differences between regions and states and their causes are analyzed to provide decision-making basis for the establishment of a high-quality and efficient operating mechanism of the medical and health service system. Methods The data in this study are derived from the Statistical Yearbook of Xinjiang from 2017—2021 and the Annual Report of Health Statistics of Xinjiang from 2016—2020. The research object is the medical and health service system (including grassroots medical and health institutions, hospitals, and professional public health institutions). Based on previous literature research and the availability of data, input and output indicators are determined, and GDP per capita, year-end population, and government health expenditure are selected as environmental variables. Through a three stage DEA model, The method of excluding environmental factors and random errors analyzes the operational efficiency of Xinjiang's medical and health service system during the 13th Five Year Plan period from a static perspective; Dagum Gini coefficient and Moran index were used to analyze the efficiency value and explore whether there was spatial dependence. Results The DEA model shows that, without considering the impact of environmental factors and random errors, the overall efficiency of the medical and health service system in Xinjiang during the 13th Five Year Plan period is relatively good, with an average comprehensive efficiency of 0.919; The SFA regression results showed that the increase in government health expenditure can improve the efficiency of the medical and health service system (P<0.01); Excluding the impact of environmental factors and random interference, the average comprehensive efficiency of the medical service system in Xinjiang is 0.893, mostly in an increasing or constant state of scale. The annual contribution rates of intra regional differences, inter regional differences, and hypervariable density to regional differences are 36.05%, 33.32%, and 30.63%, respectively. The results of the Moran index show that the operational efficiency of the medical service system in Xinjiang only has a spatial correlation between 2016 and 2019 (P=0.096, P=0.040). Conclusions During the 13th Five Year Plan period, the operational efficiency of the medical and health service system in Xinjiang was in a fluctuating state. Compared to pure technical efficiency, Bortala Mongolian Autonomous prefecture and Kizilsu Kirgiz Autonomous Prefecture urgently need to improve their scale and structure. Among environmental factors, government health expenditure has a greater impact on efficiency, and the government can appropriately increase health investment. There is a significant difference in efficiency between different regions and states, and there are significant differences between territories, indicating that each region needs to address the issue of insufficient efficiency in a targeted manner.

In surrogate assisted many objective optimization, conflicting uncertainties of surrogate between objective is a challenge. Hence, an many objective optimization algorithm with uncertainty of surrogate is proposed called, US-MOEA. The main work of this paper is as follows: first of all, infill criterion based on the uncertainty of predicted value is proposed to select promising solutions for re-evaluating by expensive optimization objective function. Then, in order to reduce the computational resources, a method based on non-dominated sorting is used to select some individual as train sample. In order to verify the effectiveness of proposed algorithm, the DTLZ and WFG test suits problem are applied and compare with five the-state-of-art algorithms proposed in recent years. The experimental results illustrate that the US-MOEA is an effectively method for solving expensive many objective optimization problems.

To achieve field crop and weed recognition on devices with limited storage resources and computational capabilities, a lightweight semantic segmentation network based on improved DeepLabv3+ is proposed. Firstly, MobileNet v2 is used as the feature extraction backbone for DeepLabv3+, where the residual modules are replaced with dual-branch residual modules and the last two convolutional layers are removed to reduce the model parameters. Secondly, group-wise pointwise convolution is introduced in the Atrous Spatial Pyramid Pooling module, replacing standard convolutions with depthwise dilated convolutions, and performing multi-scale feature fusion on the convolved feature maps to enhance the extraction of deep features for crops and weeds. Lastly, the original non-linear activation functions are replaced with the Leaky ReLU activation function to improve segmentation accuracy. Experimental results show that the improved DeepLabv3+ achieves an mIOU (Mean Intersection over Union) of 86.75% with only 0.69M parameters, and achieves an FPS (Frames Per Second) of 98. Compared to the original DeepLabv3+ and three typical lightweight semantic segmentation networks, it has the lowest parameter count and the highest segmentation accuracy among the compared lightweight networks.

The prevalence of respiratory diseases has made masks play an important role, which has brought new challenges to face recognition algorithms. Inspired by the multi-scale feature fusion model, a Pyramid Vision Transformer (PVT) based face mask feature extraction model is proposed. The model introduces self-attention mechanism to extract rich face information, and realizes multi-scale attention to mask faces by fusing multi-level feature vectors of PVT. Compared with traditional feature fusion model, the model has higher recognition accuracy and fewer parameters. In addition, the model adopts Sub-center ArcFace loss function to improve robustness. The model was trained on a large scale simulated mask face dataset, and tested and evaluated on ordinary face, simulated mask face and real mask face dataset respectively. The experimental results show that the proposed method has higher recognition accuracy than other mainstream methods, and is an effective mask face recognition method.
