Plant phenotyping is essential for understanding and managing plant growth and development. 3D point clouds provide a better understanding of plant 3D structures. Point cloud segmentation is the basis for studying the 3D structure of plants through 3D point clouds, and accurate point cloud segmentation is crucial for extracting relevant phenotypic parameters. In this study, cabbage was used as an example, and a plant point cloud segmentation method combining deep learning algorithms and clustering algorithms was proposed. Specifically, a cabbage point cloud dataset was constructed using a 3D scanning platform. The ASAP attention module was incorporated into the PointNet++ model, resulting in the improved ASAP-PointNet model. Superior semantic segmentation performance on the cabbage point cloud dataset was demonstrated by this model. The workflow of the DBSCAN algorithm was also optimized, which exhibited enhanced performance in organ-level plant point cloud segmentation experiments. Subsequently, five phenotypic features were extracted. The experimental results revealed that an accuracy of 0.95 and an intersection over union (IoU) of 0.86 for semantic segmentation were achieved by the ASAP-PointNet model. The correlation coefficients between the four phenotype parameters (plant height, leaf length, leaf width, and leaf area) and their corresponding measured values were 0.96, 0.91, 0.95, and 0.94, respectively. An automated data analysis, from plant 3D point clouds to phenotypic parameters, is enabled by the proposed method, which serves as a valuable reference for plant phenotype research. © 2023, The Authors.

THE IMPORTANCE OF CORRECT LANGUAGE LEARNING CONCEPTS

引用

Chinese Journal of Applied Linguistics 2002年第1期25卷 48-51,65页

作者： zhang ruwen Zhejiang University of Finance and Economics

This paper analyses the language learning concepts of some non-English major students and their influence on the students' language achievements by keeping track of 100 students from Band 1 to Band 4. The paper demonstrates that language learning concepts have direct influence on study methyls, thus deciding final language achievements. It suggests that having a correct language learning concept is important not only for English majors but for non-English majors as well.

Background/Aims Stress hyperglycemia is common in critical illness but it has not been clearly studied in patients with acute pancreatitis (AP). This study aimed to investigate the specific blood glucose (BG) level that defines stress hyperglycemia and to determine the impact of stress hyperglycemia on clinical outcomes in AP patients. Methods AP patients admitted <= 48 h after abdominal pain onset were retrospectively analyzed. Patients were stratified by pre-existing diabetes and stress hyperglycemia was defined using stratified BG levels for non-diabetes and diabetes with clinical outcomes compared. Results There were 967 non-diabetic and 114 diabetic (10.5%) patients met the inclusion criteria and the clinical outcomes between these two groups were not significantly different. In non-diabetes, the cut-off BG level of >= 180 mg/dl was selected to define stress hyperglycemia with an 8.8-fold higher odds ratio for persistent organ failure (POF) (95% CI 5.4-14.3;P < 0.001). For diabetes, >= 300 mg/dl was selected with a 7.5-fold higher odds ratio for POF (95% CI 1.7-34.3;P = 0.009). In multivariable logistic regression, stress hyperglycemia was independently associated with POF, acute necrotic collection, major infection and mortality. The combination of BG and systemic inflammatory response syndrome (SIRS) score in predicting POF was better than SIRS or Glasgow score alone. Conclusions This study identifies a cut-off BG level of >= 180 mg/dl and >= 300 mg/dl was optimal to define stress hyperglycemia for non-diabetic and diabetic AP patients, respectively. There was a significant relationship between stress hyperglycemia and adverse clinical outcomes.

SSRN 2023年

Stomata are important channels for gas exchange between inside and outside plants, regulating the circulation of carbon and water. The research of stomata has become an important field of crop breeding and stress analysis, and stomatal feature detection is a key step in stomatal research. Aiming at the shortcomings of traditional stomata measurement methods such as slow efficiency, low accuracy and high labor cost, this research proposed an extraction method of lettuce leaf stomata characteristics using improved U-net. For the problem of edge information loss caused by multiple down-sampling of U-net network, a hybrid dilated convolution module was proposed and overlapping pooling was used to replace the standard pooling to improve the accuracy of network recognition of small target objects. The CBAM(Convolutional Block Attention Module) was integrated, the feature weights of each channel were integrated, effective features were extracted from a large number of features, and the NAdam optimization function was selected to accelerate network convergence and reduced resource occupancy. Using the OpenCV library, the MFe(Measurement Feature) measurement algorithm was designed to measure the long and short axis, area and stomatal density of lettuce leaves. Experiments show that: the improved U-net network has the Mean Intersection over Union(MIoU) increased by 3.11%, Pixel Accuracy(PA) increased by 3.26%, and Mean Pixel Accuracy(MPA) increased by 3.02%, compared with the original network. The proposed network performs excellently. This method provides a reference for the research of plant response to the environment and growth regulation in the microscopic dimension. © 2023, The Authors. All rights reserved.

Facile construction of N-doped TiO2 nanohybrids with enriched oxygen vacancies for enhanced photocatalytic green hydrogen production

A series of N-doped TiO2 nanohybrids (xN-TiO2) were successfully prepared via a facile solvothermal route by using oleylamine as N source, for enhancing photocatalytic hydrogen evolution reaction (HER). The doped-N atoms induced the generation of abundant oxygen vacancies (OVs). The resulted impurity and defect levels in xN-TiO2 contributed to their narrowed band gap, enhanced visible light response, and promoted separation and transfer of photogenerated carrier. Moreover, the N-doping optimized the distribution of OVs, and therefore affect the conduction band (CB) location of catalyst. Herein, the 3N-TiO2 catalyst with excellent photoelectric properties and appropriate CB location, showed the photocatalytic HER rate of 3984.71 μmol h−1 g−1 under the simulated sunlight irradiation, which was 5.5 and 29.0 times that of the undoped TiO2 and commercial P25, respectively. Meanwhile, the 3N-TiO2 catalyst exhibited the excellent stability and salt-resistance. This work provides a novel insight for the band alignment of photocatalysts by defects regulation, and opens the new possibility for synthesizing N-doped TiO2 catalyst by a more practical and safe method. © 2025 Elsevier Ltd and Techna Group S.r.l.

Background: Controversies existed surrounding the use of hematocrit to guide early fluid therapy in acute pancreatitis (AP). The association between hematocrit, early fluid therapy, and clinical outcomes in ward AP patients needs to be investigated. Methods: Data from prospectively maintained AP database and retrospectively collected details of fluid therapy were analyzed. Patients were stratified into three groups: Group 1, hematocrit < 44% both at admission and at 24 h thereafter;Group 2: regardless of admission level, hematocrit increased and >44% at 24 h;Group 3: hematocrit >44% on admission and decreased thereafter during first 24 h. "Early" means first 24 h after admission. Baseline characteristics, early fluid rates, and clinical outcomes of the three groups were compared. Results: Among the 628 patients, Group 3 had a higher hematocrit level, greater baseline predicted severity, faster fluid rate, and more fluid volume in the first 24 h compared with Group 1 or 2. Group 3 had an increased risk for persistent organ failure (POF;odds ratio 2, 95% confidence interval [1.1-3.8], P = 0.03) compared with Group 1 after adjusting for difference in baseline clinical severity scores, there was no difference between Group 2 and Group 3 or Group 1. Multivariate regression analyses revealed that hemoconcentration and early faster fluid rate were risk factors for POF and mortality (both P < 0.05). Conclusions: Hemoconcentration is associated with faster fluid rate and POF in ward AP patients. Randomized trials comparing standardized early fast and slow fluid management is warranted.
