Abstract (sommario):
Fruit quality is a critical factor in the produce industry, affecting producers, distributors, consumers, and the economy. High-quality fruits are more appealing, nutritious, and safe, boosting consumer satisfaction and revenue for producers. Artificial intelligence can aid in assessing the quality of fruit using images. This paper presents a general machine learning model for assessing fruit quality using deep image features. This model leverages the learning capabilities of the recent successful networks for image classification called vision transformers (ViT). The ViT model is built and trained with a combination of various fruit datasets and taught to distinguish between good and rotten fruit images based on their visual appearance and not predefined quality attributes. The general model demonstrated impressive results in accurately identifying the quality of various fruits, such as apples (with a 99.50% accuracy), cucumbers (99%), grapes (100%), kakis (99.50%), oranges (99.50%), papayas (98%), peaches (98%), tomatoes (99.50%), and watermelons (98%). However, it showed slightly lower performance in identifying guavas (97%), lemons (97%), limes (97.50%), mangoes (97.50%), pears (97%), and pomegranates (97%).

Abstract (sommario):
Abstrak. Masyarakat suku Gayo sebagian besar memiliki pemahaman tentang pemanfaatan tumbuhan hutan yang dapat dikonsumsi baik untuk bahan pangan maupun sebagai obat-obatan. Atas dasar ini penting diteliti agar dapat memberikan informasi kepada masyarakat maupun pemerintah bahwa terdapat jenis-jenis tumbuhan hutan yang dapat dikonsumsi untuk bahan pangan non pokok yang hidup secara liar dan dikonsumsi oleh suku Gayo yang berdomisili di Terangun. Penelitian ini menggunakan metode wawancara dan observasi. Hasil dari penelitian menunjukkan bahwa terdapat 34 jenis tumbuhan liar yang terdiri dari 22 suku tumbuhan masih dimanfaatkan oleh suku Gayo di Terangun sebagai bahan pangan non pokok. Jenis tumbuhan yang paling banyak digunakan yaitu ranti (rukut) dengan penggunaan sebesar 97,50% sehingga dikategori sangat tinggi. Bagian atau organ tumbuhan hutan yang dapat dimanfaatkan sebagai bahan pangan yaitu buah, batang, daun, tunas dan bunga. Organ tumbuhan yang paling sering digunakan yaitu buah sebanyak 47%. Meskipun penggunaan organ buah paling tinggi dari organ lainnya namun penggunaan organ ini masih masuk ke dalam katergori rendah. Tumbuhan hutan tersebut dimanfaatkan dengan cara dimasak, dikupas lalu dimakan, dimakan secara langsung dan dikeringkan kemudian dimakan. Cara pengolahan tumbuhan yang paling sering dilakukan adalah dengan cara dimasak dan pengolahan dengan cara ini dilakukan sebesar 45% dari penggunaan lainnya. Penggunaan dengan cara dimasak juga masih termasuk ke dalam kategori rendah.Abstract. Most of the Gayo people have an understanding of the use of forest plants that can be consumed both for food and as medicine. On this basis, it is important to research in order to provide information to the public and the government that there are forest plant species that can be consumed for non-staple foods that live wild and are consumed by the Gayo tribe who live in Terangun. This research uses interview and observation method. The results of the study indicate that there are 34 types of wild plants consisting of 22 plant tribes that are still used by the Gayo tribe in Terangun as non-staple food. The most widely used plant species is black nightshade with a usage of 97.50% so that it is categorized as very high. Parts or organs of forest plants that can be used as food are fruits, stems, leaves, shoots and flowers. The most frequently used plant organ is fruit as much as 47%. Although the use of fruit organs is higher than other organs, the use of these organs is still in the low category. The forest plants are used by cooking, peeling and then eating, eaten directly and dried and then eaten. The method of processing plants that is most often done is by cooking and processing in this way is carried out for 45% of other uses. The use by cooking is also still included in the low category.

Abstract (sommario):
When teaching mathematical problem-solving is mentioned, the name of Pólya György inevitably comes to mind. Many problem-solving lessons are planned using Pólya's steps and helping questions, and teachers often rely on his heuristics even if their application happens unconsciously. In this article, we would like to examine how the two phases, Making a plan and Looking back, can be realized in a secondary school mathematics lesson. A case study was designed to observe and analyse a lesson delivered using cooperative work.

Abstract (sommario):
Based on the literature, Pólya was influential in problem-posing research. The present paper draws attention to a book written with Pólya's collaboration, which has not yet received sufficient emphasis in the problem-posing literature. On the other hand, Pólya's impact on mathematics education in Hungary has been significant, including the problem-posing paradigm. Two works, published only in Hungarian, that rely heavily on problem-posing are highlighted. Furthermore, it is presented how problem-posing appeared in the Hungarian Complex Mathematics Teaching Experiment (1962-78) led by Tamás Varga. Subject Classification: 97D50

Seed Priming: It’s Effect on Seed Germination and Seedling Emergence of Spring Varieties in Kapilvastu District, Nepal". International Journal for Research in Applied Sciences and Biotechnology 8, n. 2 (7 aprile 2021): 196–201. http://dx.doi.org/10.31033/ijrasb.8.2.25.
Abstract (sommario):
This study aimed to determine the effect of seed priming (on-farm, hydro, halo, osmo, vitamin c priming, and hardening) on the germination and seedling growth of spring rice varieties: hardinath-3, hardinath-1, and chaite-5 at ambient room temperature. A factorial completely randomized design (CRD) was carried out with two factors: methods of priming and varieties at agriculture knowledge center (AKC), kapilbastu during march 2020. There were, in total, 21 treatment combinations and four replications. Parameters observed were germination percentage, speed of germination, vigor index, root length, shoot length, fresh weight, and dry weight of rice seedlings. Hardinath-3 had superior performance in terms of germination percentage (95.35 %), vigor index (183.86), root length (11.51 cm) and shoot length (7.39 cm) compared to hardinath-1 and chaite-5; the speed of germination, however, was greater in hardinath-1. Seed hardening - alternate soaking (tap water for 24 hours) and drying - induced higher germination percentage (94.91 %), speed of germination (96.00), and vigor index (197.43) than did other priming methods; germination percentage of vitamin c primed seeds (94.75 %), nevertheless, were at statistical par with hardened seeds. Hardened hardinath-3 seeds were better in regards to germination percentage (97.50 %) and root length (12.92 cm), while the speed of germination (97.50) and vigor index (210.50) was greater in hardened hardinath-1. Vitamin c primed seeds of hardinath-3 and hardinath-1 were finer with dry weight, shoot length, and vigor index. In conclusion, farmers' are suggested to hardened seeds of hardinath-3 before sowing to promote uniform germination and growth.

Abstract (sommario):
AbstractPaleoenvironmental data, including pollen and sediment analyses, radiocarbon ages, and tephra identifications of a core recovered from a fen, provide a ca. 16,500 14C yr B.P. record of late Quaternary vegetation and climate change in the Long Valley area of west-central Idaho. The fen was deglaciated prior to ca. 16,500 14C yr B.P., after which the pollen rain was dominated by Artemisia, suggesting that a cold, dry climate prevailed until ca. 12,200 14C yr B.P. From ca. 12,200 to 9750 14C yr B.P. temperatures gradually increased and a cool, moist climate similar to the present prevailed. During this period a closed spruce–pine forest surrounded the fen. This cool, moist climate was briefly interrupted by a dry and/or cold interval between ca. 10,800 and 10,400 14C yr B.P. that may be related to the Younger Dryas climatic oscillation. From ca. 9750 to 3200 14C yr B.P. the regional climate was significantly warmer and drier than at present and an open pine forest dominated the area around the fen. Maximum aridity occurred after the deposition of the Mazama tephra (ca. 6730 14C yr B.P.). After 3200 14C yr B.P. regional cooling brought cool, moist conditions to the area; the establishment of the modern montane forest around the fen and present-day cool and moist climate began at ca. 2000 14C yr B.P.

Abstract (sommario):
The present work describes a neural particle classifier system based on topological mapping of the segmented information provided by a high-energy calorimeter, a detector that measures the energy of incoming particles. The achieved classification efficiencies are above 97.50% for the higher energy particle beams, even when experimental data exhibit unavoidable contamination due to the particle beam generation process, what could jeopardize the classifier performance. Some deterioration in the performance for the lower energy range is also discussed. The reduction on the dimensionality of the data input space caused by the topological mapping may be very helpful when online implementation of the classifier is required.

Abstract (sommario):
We present diffraction-limited speckle-masking observations of the central object HD 97950 in the giant HII region and star cluster NGC 3603. Twenty-eight stellar components have been detected in the 6.″3 x 6.″3 field from our reconstructed images. Four different filter combinations were used for the selection of distinct spectral regions comprising Hα emission, the main Wolf-Rayet and Of-type emission lines, and two continuum bands. Stellar components having WN-type characteristics have been found. A color-magnitude diagram has been constructed. Isochrone fits yield a cluster age of about 3.2 Myr, which is in accordance with the time-scale of Wolf-Rayet star evolution.

Abstract (sommario):
NGC 3603 is the most massive optically visible H II region in our Galaxy and is considered to be the Galactic analogue to 30 Doradus and, thus, a prototype of the starburst phenomenon. Its core, known as WR 43 (HD 97950), contains several dozens of O-B0 stars within 35″. These have been studied with very high resolution in the optical and near-IR. Melnick, Tapia & Terlevich (1989) concluded that the starburst cluster has an age spread of 1 to 2 Myr and that its boundaries extend to ∼60″, while Eisenhauer et al. (1998) determined that the lower mass stars in the core are younger than 1 Myr.

Abstract (sommario):
This paper describes the results of recognizing handwritten signatures. For the experiments, the database of handwritten signatures BHSig260-Bengali, BHSig260-Hindi, CEDAR and TUIT was used. For classification, four options were used to reduce the signatures to sizes: 200×120, 250×150, 300×150 and 400×200 pixels. These images served as input for the proposed network architecture. As a result of testing the proposed approach, the average accuracy of correct classification of signatures on images of size 250×150 was achieved: for the CEDAR database it was 94.38%, for the BHSig260-Hindi database it was 95.63%, for the BHSig260-Bengali database it was 97.50% and for TUIT base is 90.04%.

Abstract (sommario):
In this study, we propose a method for inspecting the condition of hull surfaces using underwater images acquired from the camera of a remotely controlled underwater vehicle (ROUV). To this end, a soft voting ensemble classifier comprising six well-known convolutional neural network models was used. Using the transfer learning technique, the images of the hull surfaces were used to retrain the six models. The proposed method exhibited an accuracy of 98.13%, a precision of 98.73%, a recall of 97.50%, and an F1-score of 98.11% for the classification of the test set. Furthermore, the time taken for the classification of one image was verified to be approximately 56.25 ms, which is applicable to ROUVs that require real-time inspection.

Journal of Computational and Theoretical Nanoscience 17, n. 1 (1 gennaio 2020): 61–67. http://dx.doi.org/10.1166/jctn.2020.8630.
Abstract (sommario):
Three-dimensional representation of facial bone surface is needed in the virtual surgical planning for orthognathic surgery. Segmentation of facial bone surface from computed tomography images is first step in developing the 3D model. This paper focuses on segmentation of mandible bone using active contour segmentation of Insight Segmentation and Registration Toolkit library. The results are given as 3D stereo lithographic image. The result is compared with the ground truth image segmented by an expert radiologist. Various evaluation metrics are used for finding the segmentation accuracy and the result has given segmentation accuracy of 97.50%. Therefore, this method can be used as an initial step in automatic cephalometric land marking, an important task in virtual surgical planning for orthognathic surgery.

Abstract (sommario):
The purpose of this article is to weigh up the foremost imperative features of Chronic Kidney Disease (CKD). This study is based mostly on three cluster techniques like; K means, Fuzzy c-means and hierarchical clustering. The authors used evolutionary techniques like genetic algorithms (GA) to extend the performance of the clustering model. The performance of these three clusters: live parameter purity, entropy, and Adjusted Rand Index (ARI) have been contemplated. The best purity is obtained by the K-means clustering technique, 96.50%; whereas, Fuzzy C-means clustering received 93.50% and hierarchical clustering was the lowest at 92. 25%. After using evolutionary technique Genetic Algorithm as Feature selection technique, the best purity is obtained by hierarchical clustering, 97.50%, compared to K –means clustering, 96.75%, and Fuzzy C-means clustering at 94.00%.

Abstract (sommario):
Agile software development methods, especially Scrum, are commonly used in software development companies. For this reason, our goal was that our undergraduate students gain experience as Scrum development team members and our master's students as agile leaders. To this end, we had redesigned and linked an undergraduate and a master's course, and launched the new course in the spring of 2021. The success of our approach was confirmed by a questionnaire survey of 86 undergraduate and 27 master's students. A/B testing was also performed. Our approach is a novelty compared to solutions where the Scrum Master is a course member, an instructor, or a university employee. In addition to being resource-efficient, it also offers master's students an unparalleled opportunity to develop agile leadership skills.

Abstract (sommario):
AbstractWe use photometry in the F220W, F250W, F330W, F435W filters from the High Resolution Channel of the Advanced Camera for Surveys and photometry in the F555W, F675W, and F814W filters from the Wide Field and Planetary Camera 2 aboard the Hubble Space Telescope to derive individual stellar reddenings and extinctions for member stars in the HD 97950 cluster in the giant H ii region NGC 3603. Within the standard deviation associated with E(λ−F555W)/E(F435W−F555W) in each filter, the cluster extinction curve at ultraviolet wavelengths tends to be greyer than the average Galactic extinction laws from Cardelli et al. (1989) and Fitzpatrick et al. (1999). It is closer to the extinction law derived by Calzetti et al. (2000) for starburst galaxies, where the 0.2175 μm bump is absent.

Abstract (sommario):
Investigations were carried out at Vasantdada Sugar Research Institute (VSI), Manjari, Pune to assess the performance of elite sugarcane genotypes under agro-climatic condition of peninsular zone during 2022. Eight sugarcane genotypes along with three local checks were evaluated for their growth and yield attributes, cane yield and quality performance. The behavior of the genotypes with regard to cane yield, yield components and quality remained variable during the study. The data indicated that the application of 25% of extra fertilizer dose over RDF showed numerically higher cane and CCS yield (121.33 and 18.69 t/ha). Genotype Co 16006 recorded maximum germination (66.39%), tiller population (97.50 thousand/ha) and Cane and CCS yield (140.07 and 22.65 t/ha) compared to the rest of the genotype. Superior juice quality was observed in CoVSI 16121.

Abstract (sommario):
One pitfall in 24-hour urine collection is the input of incorrect urinary volume by the reference laboratory. This may lead to an incorrect diagnosis of pheochromocytoma or paraganglioma. A 48-year-old African-American woman was seen in the clinic for an elevated 24-hour urine metanephrine screen during workup for secondary hypertension. Urine volume was found to be incorrectly inputted by the lab as 9750 mL rather than 975 mL. The urinary metanephrines were then recalculated and the 24-hour urinary metanephrines resulted within normal limits. This case highlights this unique and potentially under-recognised error in testing with 24-hour urine volume collection.

Abstract (sommario):
The purpose of this study is to evaluate the association of electronic nicotine product (ENP) use and its respiratory manifestations in a nationally representative sample of adolescents in the US. Cross-sectional evidence from 9750 adolescents in wave 3 (October 2015–October 2016) of the Population Assessment of Tobacco and Health (PATH) survey was used. Adjusting for demographics, lifetime number of cigarettes and cigars used, home rules about tobacco use, and tobacco used by other household members, we used logistic regression models to examine associations between ENP use and its respiratory manifestations in the past year. Among 9750 adolescents, 12% (n = 1105) used ENP in the past year. Compared to non-users, past-year ENP-users had 37% higher odds of wheezing in general (Adjusted Odds Ratio (AOR) = 1.37, 95% Confidence interval (CI): 1.11–1.71, p = 0.005) and higher odds of wheezing 4–12 times or >12 times per year versus no wheezing (AOR = 1.57, 95% CI: 1.01–2.46, p = 0.05 and AOR = 2.58, 95% CI: 1.04–6.41, p = 0.04, respectively). Additionally, odds of dry cough at night were 23% higher among ENP-users than among non-users (AOR = 1.23, 95% CI: 1.04–1.46, p = 0.02). There was no association between past-year ENP use and exercise-induced wheezing or asthma diagnosis. Among those with asthma, there was no evidence of an association between ENP use and long-acting inhaler or quick-relief inhaler use. ENP use among adolescents is associated with increased frequency of wheezing and dry cough. Early recognition of pulmonary clinical manifestations among young ENP users should be critical considerations in regulatory and prevention efforts to protect public health, and clinical efforts to prevent progression to serious pulmonary complications.

Abstract (sommario):
Breast cancer originates from the ducts or lobules of the breast and is the second leading cause of death after cervical cancer. Therefore, early breast cancer screening is required, one of which is mammography. Mammography images can be automatically identified using Computer-Aided Diagnosis by leveraging machine learning classifications. This study analyzes the Support Vector Machine (SVM) in classifying breast cancer. It compares the performance of three features extraction methods used in SVM, namely Histogram of Oriented Gradient (HOG), GLCM, and shape feature extraction. The dataset consists of 320 mammogram image data from MIAS containing 203 normal images and 117 abnormal images. Each extraction method used three kernels, namely Linear, Gaussian, and Polynomial. The shape feature extraction-SVM using Linear kernel shows the best performance with an accuracy of 98.44 %, sensitivity of 100 %, and specificity of 97.50 %.

Abstract (sommario):
The study was conducted using two ELISA methods - the liquid phase blocking ELISA (LPBE) and solid phase competition ELISA (SPCE) for the detection of foot-and-mouth disease virus (FMDV) serotype A- and O-specific antibodies of different cattle breeds in Turkey. These methods were compared in 426 cattle previously vaccinated with oil-adjuvanted bivalent vaccine as well as in sera from 40 cattle with no history of foot-and-mouth disease infection or vaccination. The results were found that SPCE had a better specificity (serotype A; 100% and serotype O; 97.50%) than LPBE (serotype A 95.00% and serotype O 92.50%). Sensitivity of SPCE had also better values (serotype A; 99.30% and serotype O; 98.59%) than LPBE (serotype A; 97.89% and serotype O; 96.48%). The results of the present study showed that the SPCE method is more reliable than LPBE.
