This research aims to study the effect of using organic fertilizers on the growth and yield of soybeans. Besides, to study the selection of the best types of organic fertilizers to increase the soil's ability to absorb water so that it can increase yield even in drought conditions. The research was carried out in the Faculty of Agriculture screen house, Indonesian Muslim University, Makassar, with the type of alfisol soil. The design used as factorial based on a randomized block design, which consisted of 2 factors. The first factor is the use of organic fertilizers, namely without organic fertilizers (P0), chicken manure (P1), Azolla compost (P2), and bokashi waste (P3). The second factor is the quantity of water supply, namely 350 mm/season (Al), 450 mm/season (A2), and 550 mm/season (A3). The results showed an interaction between the type of organic fertilizer and the amount of water supply on the total dry weight of the plant at harvest, the number of seeds, and the percentage of seed success. The enormous total dry weight of plants and the largest number of sources occurred in the combination of giving chicken manure and a water supply of 550 mm/season. Meanwhile, the highest percentage of seeds was in the variety of Azolla fertilizer treatment and water supply of 350 mm/season. The water supply treatment also significantly affects plant height, the number of leaves, and plants' total dry weight. Simultaneously, the yield components, namely the dry weight of seeds and the weight of 100 seeds with a water supply of 550 mm/season produced the best results.

Mathematical reasoning ability is one of the abilities that students must master. Influencing factors include math anxiety. This study analyzes and describes mathematical reasoning ability based on mathematics anxiety in junior high school students. The type of research conducted is descriptive qualitative research. This research was conducted at UPT SMP Negeri 17 Gresik class VII B with three students as research subjects for three categories of mathematical anxiety: high, medium, and low. Research data was obtained from mathematics anxiety questionnaires, reasoning ability tests, and interviews. Based on the results of the analysis, it was found that students with low levels of mathematical anxiety could fulfill all indicators of mathematical anxiety, and students with moderate levels of mathematical anxiety fulfilled three indicators of mathematical reasoning, namely making conjectures, manipulating mathematics, and determining patterns or properties of mathematical phenomena. Learners with high levels of mathematical anxiety only fulfill one indicator of mathematical anxiety, namely, making conjectures. From the results of the study, it can be concluded that the higher the students' mathematical anxiety, the lower their mathematical reasoning ability, so it is recommended that educators and students pay attention to mathematical anxiety in learning to improve their mathematical reasoning ability.

One of many methods of finding solution of a system of linear equations (SLE) studied in higher education is the Gauss-Jordan method. Based on the research, students made mistakes in performing elementary row operations (ERO), forming into augmented matrices, and even basic understanding of row subtraction and this has an effect on determining the solution of an SLE. For this reason, it is necessary to analyze the learning obstacles that occur in determining the solution of LES using the Gauss-Jordan method. This qualitative research is part of the Didactical Design Research (DDR). This research was conducted at a university in East Nusa Tenggara (NTT) involving 20 students as preservice mathematics teacher. The technique of this research is diagnostic test and interview. The results show that some of the obstacles faced by students are insufficient understanding of ERO, classifying reduced row-echelon form (RREF), and representing MEBT into SPL solutions. This study recommends that teachers create teaching materials that minimizes learning obstacles experienced by students.

BACKGROUND:

The Chinese population ranks among the highest globally in terms of stroke prevalence. In the clinical diagnostic process, radiologists utilize computed tomography angiography (CTA) images for diagnosis, enabling a precise assessment of collateral circulation in the brains of stroke patients. Recent studies frequently combine imaging and machine learning methods to develop computer-aided diagnostic algorithms. However, in studies concerning collateral circulation assessment, the extracted imaging features are primarily composed of manually designed statistical features, which exhibit significant limitations in their representational capacity. Accurately assessing collateral circulation using image features in brain CTA images still presents challenges.

METHODS:

To tackle this issue, considering the scarcity of publicly accessible medical datasets, we combined clinical data with imaging data to establish a dataset named RadiomicsClinicCTA. Moreover, we devised two collateral circulation assessment models to exploit the synergistic potential of patients’ clinical information and imaging data for a more accurate assessment of collateral circulation: data-level fusion and feature-level fusion. To remove redundant features from the dataset, we employed Levene’s test and T-test methods for feature pre-screening. Subsequently, we performed feature dimensionality reduction using the LASSO and random forest algorithms and trained classification models with various machine learning algorithms on the data-level fusion dataset after feature engineering.

RESULTS:

Experimental results on the RadiomicsClinicCTA dataset demonstrate that the optimized data-level fusion model achieves an accuracy and AUC value exceeding 86%. Subsequently, we trained and assessed the performance of the feature-level fusion classification model. The results indicate the feature-level fusion classification model outperforms the optimized data-level fusion model. Comparative experiments show that the fused dataset better differentiates between good and bad side branch features relative to the pure radiomics dataset.

CONCLUSIONS:

Our study underscores the efficacy of integrating clinical and imaging data through fusion models, significantly enhancing the accuracy of collateral circulation assessment in stroke patients.
Shear Properties and Pore Characteristics of Soil-Rock Mixtures Under Dry-Wet Cycling
Authors: Wang Siwei , Wang Guinan , Li Shuyi
Published: May 2024

The mechanical properties of soil-rock mixture (S-RM) can deform significantly under the influence of dry-wet cycles, affecting the safety of high-fill projects. A drying device was developed to perform direct shear tests on S-RM. Large-scale direct shear tests were carried out under the action of dry-wet cycling to study the effect of dry-wet cycling on the mechanical properties of S-RM. The open-source ImageJ software was used to identify the number and area of pores in the binary image, and the pore characteristics of S-RM under dry-wet cycles were analyzed. The results show that the section of post-peak in the shear stress-strain curve softens under the natural state (no dry-wet cycles), but it plasticizes under the application of the dry-wet cycles. The cohesion of S-RM particles is affected by the dry-wet cycling. It decreases significantly under the first dry-wet cycle and then decreases gradually for each successive cycle, after which it stabilizes during the fifth dry-wet cycle. The internal friction angle is not affected to a large degree. The effect of a dry-wet cycle on pores with different areas is significantly different. The pores with initial sizes of 0.5–10 mm2 decrease, while pores with other initial sizes are hardly affected by the dry-wet cycling. This paper quantitatively analyzed the relationship between the surface two-dimensional porosity and S-RM's cohesion and peak strain.
