Published: October 2024

A few decades ago, quality assessment was a significant challenge in agriculture, even with tiny amounts of agricultural products. They are subject to diseases, pesticides, and environmental variables that have led to challenges to quality and safety. The quality evaluation of these items serves a crucial function in quality control and increases productivity before consumption. This paper proposes a deep neural network for solving Indian tomato diversity problems based on the assessment of their features. This study was carried out using four different categories of south Indian cherry tomatoes, i.e., spot, BER, calyx, and non-calyx. Thirty (30) relevant features were taken from an RGB-HIS color space: textural color moments, gray level co-occurrence matrix (GLCM), and defective proportion. They were then normalized in MS-EXCEL with a Min-Max function and fed into a multilayer perception deep neural network (MLP-DNN) and a convolutional neural network (CNN), respectively. The MLP-DNN was made with ten (10) hidden layers and was used with a fine-tuned convolutional neural network (CNN) of Alex net architecture with eight (8) learned layers to do grading and detection separately using MATLAB 2018a software. The results of training, testing, and validating both networks showed that they did an excellent job of solving the two-class problem (good and bad), with an overall prediction accuracy of more than 97% and a bit of loss function in both cases. However, the algorithms can be improved and employed to detect defects and sort fruits or vegetables of all kinds in the agro-industry with a larger dataset to reduce overfitting and increase validation accuracy in the future.
Speech Isolation and Recognition in Crowded Noise Using a Dual-Path Recurrent Neural Network
Authors: Ibraheem Zainab Haider , Shihab Ammar Ibraheem
Published: October 2024

Speech separation is crucial for effective speech processing in multi-talker conditions, especially in real-time, low-latency applications. In this study, the Time-Domain Audio Separation Network (TasNet) and Dual-Path Recurrent Neural Network were used to perform a time-domain multiple-speaker speech separation challenge. One-dimensional conventional recurrent neural networks (RNNs) are not capable of accurately simulating long sequences. When their receptive length exceeds the sequence field, 1-D CNNs cannot recreate utterance-level sequences. Dual-Path Recurrent Neural Network (DPRNN) breaks up the lengthy sequential input that progressively performs intra- and inter-chunk operations with input lengths proportional to the square root of the beginning sequence length. Model outputs are more efficient than earlier systems, improving performance on the Libri Mix dataset. Investigations show that the DPRNN, sample-level modeling, and time-domain audio separation network can replace present methods. EEND-SS and other separation algorithms perform worse than DPRNN. The suggested model was able to achieve (12.376) SI-SDR, (0.969) STOI (short-time objective intelligibility), (12.363) SDR, (9.363) DER, and (97.193) SCA.
Review: Noise Reduction Techniques for Enhancing Speech
Authors: Nasir Ruqaya Jamal , Abdulmohsin Husam Ali
Published: October 2024

Speech is a signal produced by humans to interact and communicate. Different information is gained from speech signals, such as the language being spoken, emotion, gender, speaker identification, and other information. Speech signals are exposed to different noises, which can be generated at the beginning of the speech or during the transmission. Due to this problem, noise reduction processes are an interesting field in different communication application systems that cultivate the intelligibility and quality of speech signals. It refers to removing or reducing the background noise in order to obtain an improved quality of the original speech signal without distorting the original (clean) signal. This paper reviews the state-of-the-art research, reviewing different speech enhancement filters and algorithms and comparing their performance to reach a conclusion about which is the best filter or the most effective one based on the kind of noise that was used and the most difficult noise to remove from the signal.

Published: October 2024

Microsporum canis is considered one of the filamentous fungi that cause surface fungal contagion in the humans and animals. The present study aimed to diagnose M. canis via the molecular method and differentiating its local Iraqi isolates from global isolates. Microscopic examination showed 55 specimens with M. canis from 130 specimens collected from children aged between 4-10 years suspected of dermatophytes who attended Medical City Laboratories and Baghdad Hospital in Baghdad city from 1/12/2022 to 1/3/2023. The results showed that the frequency of M. canis infections was 55/130 (42.31%). The results demonstrated significant differences in the animals' contact (p <0.0001), lesions (0.03) and habitation area (p =0.002). Whilst the ages appeared with non-significant differences (p =0.6). In order to confirm the microscopic examination and compare the Iraqi isolates with other global ones, the 55 positive results with M. canis were further diagnosed by using internal transcribed spacer (ITS) 1 and 4 universal primers with a size of 550 bp for PCR amplicons. PCR amplicons sequencing showed only one isolate of M. Canis that differed from global isolates registered in the database of NCBI. The Iraqi local isolate of M. canis was registered with accession number: OM185328. In conclusion, the PCR technique using ITS rDNA aided in confirming the detection of dermatophytes.

Published: October 2024

This study aims to evaluate the effectiveness of the Convolutional Neural Network (CNN) model in identifying periodontal disease using dental images. With the applied method, the CNN model was trained using a dataset consisting of 40 dental images and tested on 55 images to evaluate its ability to classify the images as healthy or periodontal. The evaluation results showed that the CNN model achieved an overall accuracy of 91.16%. The model precision for healthy images reached 92.39%, while the precision for unhealthy images was 91.05%. Recall sensitivity for healthy images is 91.16%, and for F1-Score images is 91.07%. The data shows that the model has better performance in identifying healthy images compared to periodontal images. To improve the performance of the model, data augmentation techniques such as rotation, flipping, and scaling were applied, which gave a slight improvement to the results. However, the limited size of the dataset seems to be an obstacle in achieving higher accuracy. Therefore, this study recommends expanding the dataset size and applying more complex model architectures or transfer learning techniques to improve detection performance. The conclusion of this study shows that CNN models have potential for periodontal disease detection, but need further development to improve accuracy and reliability. This research contributes to the development of medical detection technology and opens a path for further research in improving periodontal disease detection systems using CNN technology.

On Ion-Acoustic Precursor Soliton Signatures of Orbital Debris in Low Earth Orbit
Authors: Resendiz Lira Pedro Alberto , Delzanno Gian Luca , Svyatsky Daniil , Koshkarov Oleksandr
Published: October 2024

Nonlinear plasma solitons have been recently proposed as a possible, indirect way to detect dangerous small orbital debris in low Earth orbit. A kinetic simulation study of the interaction between small debris flowing through a plasma at hypersonic velocity is presented, with a particular focus on whether the debris–plasma interaction leads to the formation of ion-acoustic precursor solitons. By using an electrostatic kinetic model and in the absence of an external magnetic field, simulation results where the debris is treated as a Gaussian density source are compared with those where the debris–plasma interaction is modeled self-consistently, in both one and two dimensions. While ion-acoustic solitons are formed when the debris is treated as a Gaussian density source and the ions are cold, it is shown that self-consistent debris charging with similar parameters hinders the formation of precursor solitons. This indicates that self-consistent debris charging is key to quantitative predictions of soliton formation. Additionally, when the ion and electron temperatures are comparable, as typical of conditions in low Earth orbit, Landau damping physics also hinders the formation of ion-acoustic precursor solitons. These results suggest that it will be challenging to exploit ion-acoustic precursor solitons for orbital debris detection in low Earth orbit.

Published: October 2024

Current and planned space exploration and life detection missions such as NASA Jet Propulsion Laboratory’s Mars 2020, Mars Sample Return, and Europa Clipper require record-low contamination levels. In this work, we develop a novel automated outgassing contamination species identification method using mass spectrometry data. Thanks to the existing knowledge of ASTM-E1559 and direct analysis in real-time mass spectrometry material testing methods, we improved species outgassing deconvolution and physical characterization techniques. We developed a brand-new combined approach that leverages both tests’ complementary insights into contaminants’ chemical identities. Namely, we rely on the Dromey–Foyster algorithm and the Seven Golden Rules of mass spectrometry analysis to narrow down the probable identified molecules by a factor of 10 compared to the sole use of ASTM-E1559. Furthermore, thanks to recent advances in machine learning spectral analysis, we developed a composite spectral score that ranks all candidate contaminants based on their similarity to the measurements. Ultimately, we validated an automated species identification algorithm on samples of NuSil CV4-2946, Dacron, and a spacecraft cable component. The techniques established in this work enable accurate estimations of outgassed contaminant species’ chemical structure, leading to a comprehensive understanding of the effects of outgassing on scientific objectives.

Published: October 2024

It is essential for advanced turbine design and wind-farm control strategy formulation to acquire an improved understanding of the aerodynamic behavior in the rotor plane and the wake downstream of a wind turbine under blade pitching motion, reacting to highly stochastic atmospheric conditions. Using an unsteady Reynolds-averaged Navier–Stokes simulation, the effects of the dynamic variations in blade pitch are investigated on the unsteady aerodynamic behavior of an NREL-5 MW wind turbine. The results show that the wake after a pitching maneuver exhibits a local contraction region, resulting in the leapfrogging phenomenon of tip vortices. The influences of different pitch ranges and pitch rates on the aerodynamic behavior of the wind turbine are studied. The degree of wake contraction depends strongly on the pitch range, whereas an increase in pitch rate is mainly dominated by the shed vorticity, indicating a larger deviation from the quasi-state behavior. In addition, interaction between the shed vorticity and the neighboring tip vortex is observed in the near wake under the condition at a fast pitch rate, which may have an influence on the mutual inductance instability.
Adjoint-Based Design Optimization of Stability Constrained Systems
Authors: He Sicheng , Jonsson Eirikur , Li Jichao , Martins Joaquim R. R. A.
Published: October 2024

A partial differential equation (PDE) constrained design optimization problem usually optimizes a characteristic of a dynamical system around an equilibrium point. However, a commonly omitted constraint is the linear stability constraint at the equilibrium point, which undermines the optimized solution’s applicability. To enforce the linear stability constraint in practical gradient-based optimization, the derivatives must be computed accurately, and their computational cost must scale favorably with the number of design variables. In this paper, we propose an algorithm based on the coupled adjoint method and the algorithmic differentiation method that can compute the derivative of such constraint accurately and efficiently. We verify the proposed method using several simple low-dimensional dynamical systems. The relative difference between the adjoint method and the finite differences is between [Formula: see text] to [Formula: see text]. The proposed method is demonstrated through several optimizations, including a nonlinear aeroelastic optimization. The proposed algorithm has the potential to be applied to more complex problems involving large-scale nonlinear PDEs, such as aircraft flutter and buffet suppression.

Authors: Telford Owen , Ghosh Ashok Kumar
Published: October 2024

This study investigates biomimetic heat pipes for space radiator applications, utilizing nature-inspired structures to potentially enhance heat transfer efficiency. The research addresses the imperative for improved heat dissipation mechanisms in nuclear space systems, crucial for effective thermal management. Heat pipes are passive heat transfer devices widely adopted for thermal control. The study aims to evaluate the effectiveness of a biomimetic heat pipe design in comparison to a traditional design while also validating the fabrication process through industry-made heat pipe comparisons. Innovative hot oil bath testing methods are employed to fabricate and test both heat pipe types, utilizing comprehensive thermal analysis, physical experiments, and validation techniques to assess heat transfer capabilities. Tests span varying temperature levels to analyze heat pipe behavior and performance. Findings suggest the potential for enhanced heat dissipation along the length of the biomimetic heat pipe, hinting at the biomimetic structure’s role in improving heat transfer. This study underscores the promise of biomimetic design principles and their potential for advancing heat pipe technology. Recommendations for further exploration include alternative materials, optimized testing procedures, and refined fabrication processes.

This paper aims to provide experimental methodologies for estimating the characteristics of mass transfer, namely, the Nusselt number, induced by vertical sloshing in horizontal cylindrical tanks pressurized with two-phase fluid by replicating operating conditions that would occur in tanks containing liquid hydrogen for future generation aircraft. A tank with a circular cross section, scaling a slice of an aircraft tank, is used as a test bed, and water is used as a surrogate fluid for replacing the liquid hydrogen. The paper first provides the estimation of the Nusselt number for random imposed motion and shows that, in the case of stationary processes, the Nusselt number results constant on average in time and is independent of the fluid thermodynamic state. As a consequence, the Nusselt can also be mapped for deterministic harmonic processes with variable amplitude and frequency.

Authors: А.Ю. Любимова , С.С. Перцов
Published: October 2024

Цель исследования: изучение половых и возрастных особенностей изменения массы тела и концентрации глюкозы в крови крыс, перенесших внутриутробный стресс. Материалы и методы. Исследование проведено на потомстве (n = 96) крыс Вистар: самцах и самках подсосного (21-й день), инфантильного (30-й день) и ювенильного возраста (60-й день). Беременных самок распределяли на две группы. Контрольных животных содержали в стандартных условиях вивария. Крыс опытной группы с 10-го по 16-й день беременности подвергали стрессу принудительного плавания в холодной воде (10ºC) в течение 5 мин. Массу тела и уровень глюкозы в крови потомства измеряли на 21-е, 30-е и 60-е сутки жизни. Результаты. Внутриутробный стресс приводил к снижению массы тела у самок, но не у самцов крыс на 21-й день жизни по сравнению с контролем. К 60-му дню жизни масса тела самцов превышала соответствующий показатель у самок. В отличие от интактных, внутриутробно стрессированные самки к 60-му дню жизни характеризовались уменьшением содержания глюкозы в крови по сравнению с таковым в предыдущие периоды онтогенеза. Заключение. Внутриутробный стресс оказывает влияние на изученные физиологические показатели у самок, но не у самцов животных. Это проявляется в низкой массе тела на ранней стадии постнатального онтогенеза и возрастном уменьшении концентрации глюкозы крови в более позднем периоде развития.

The aim: to investigate sex and age-specific changes in body weight and blood glucose concentration in rats undergoing intrauterine stress. Material and methods. The study was conducted on the offspring (n=96) of Wistar rats: males and females of suckling (day 21), infantile (day 30) and juvenile age (day 60). Pregnant females were allocated into two groups. Control animals were kept under standard vivarium conditions. Rats of the experimental group were subjected to the stress of forced swimming in cold water (10ºC) for 5 min from the 10th to the 16th day of gestation. Body weight and blood glucose levels of the offspring were measured on the 21st, 30th and 60th days of life. Results. Intrauterine stress led to a decrease in body weight in female, but not in male rats on the 21st day of life compared to the control. By day 60 of life, the body weight of males exceeded the corresponding index in females. In contrast to intact, intrauterine stressed females by the 60th day of life were characterized by a decrease in blood glucose content compared to that in the previous periods of ontogenesis. Conclusion. Intrauterine stress affects the studied physiological parameters in female, but not in male animals. This is manifested in low body weight at the early stage of postnatal ontogenesis and age-related decrease in blood glucose concentration in the later period of development.

Цель исследования заключалась в определении влияния кисспептина 10 на уровень гормонов в крови крыс после стрессорного воздействия. Материалы и методы. Были созданы модели рестрикционного и витального стрессов для самцов крыс линии Вистар. Измерялась концентрация гормонов плазмы крови (лютеинизирующего гормона, тестостерона, кортикостерона) после различных типов стресса методом конкурентного иммуноферментного анализа (ИФА). Результаты. Введение кисспептина 10 повышает концентрацию лютеинизирующего гормона после разных видов стресса, как при интраназальном, так и при внутрибрюшинном введении, тогда как концентрация тестостерона повышается лишь при рестрикционном стрессе и системном введении препарата. Концентрация кортикостерона значительно снижается при витальном стрессе и системном введении препарата. Заключение. Данные исследования указывают на то, что кисспептин 10 действует преимущественно центрально на структуры мозга, участвующие в реализации половой функции, независимым от регуляции половых стероидов механизмом, а также имеет стресс-лимитирующий эффект в модели психологического стресса. Изменение данных показателей уменьшает проявление компонентов полового поведения крыс.

The aim of the study was to determine the biochemical indicators of hormone levels in the plasma of male rats after stress before and after the administration of kisspeptin 10. Materials and Methods: Models of restrictive and vital stress were created for male rats of the Wistar line. The concentration of plasma hormones (luteinizing hormone, testosterone and corticosterone) was measured after different types of stress using the competitive ELISA. Results: The administration of kisspeptin 10 increases the concentration of luteinizing hormone after different types of stress, both in intranasal and intraperitoneal administration, whereas the concentration of testosterone increases only in restrictive stress and systemic administration of the drug. The concentration of corticosterone significantly decreases in vital stress and systemic administration of the drug. Conclusion: The results of the study suggest that kisspeptin-10 acts primarily centrally on brain structures involved in the realization of sexual function, independent of the regulation of sex steroids mechanism, and also has a stress-limiting effect in the model of psychological stress. The change in these indicators reduces the manifestation of sexual components of behavior in rats.

O tumor ósseo multilobular é uma neoplasia primária rara em cães que acomete ossos chatos do crânio, potencialmente maligna, localmente invasiva e de crescimento lento. Normalmente atinge cães de raças de médio a grande porte e de meia idade a idosos. As alterações clínicas irão depender do comportamento biológico do tumor e estão associadas às estruturas que sofrem compressão pela massa. O objetivo deste trabalho foi relatar o caso de tumor ósseo multilobular craniano em uma cadela, sem raça definida, de nove anos de idade. A paciente apresentou o desenvolvimento progressivo de uma massa firme na região dorsal dos ossos frontais e parietais do crânio, que resultou em ceratoconjuntivite devido à tensão excessiva da pele na região palpebral. A radiografia craniana demonstrou a presença de uma massa de grande radiopacidade e aspecto granular. O exame citopatológico evidenciou achados sugestivos de tumor ósseo multilobular, optando-se pela excisão cirúrgica da massa. Foi realizada a excisão da neoplasia por meio da divulsão dos tecidos adjacentes e secção da neoplasia na base do crânio. Devido ao grau de invasividade do tumor não foi possível o estabelecimento de margem cirúrgica. O diagnóstico foi confirmado por meio do exame histopatológico. A paciente apresentou boa recuperação após a cirurgia, inclusive da lesão ocular, porém após cinco meses houve recidiva local da neoplasia. Uma segunda intervenção cirúrgica não foi possível, pois a paciente veio a óbito por intoxicação por bufotoxina. A remoção cirúrgica da neoplasia, mesmo com margens comprometidas, melhorou significativamente a qualidade de vida da paciente.

Carcarás (Caracara plancus) são aves de rapina obrigatoriamente carnívoras. Em condições de cativeiro, é comum que estas aves, quando juvenis, apresentem quadro de osteodistrofia decorrente de alimentação inadequada e, assim, possuam uma maior predisposição a fraturas devido a este distúrbio osteometabólico. Um exemplar de C. plancus foi entregue de forma voluntária no Setor de Animais Selvagens do Hospital Veterinário da Universidade Federal de Uberlândia (UFU), em Minas Gerais, Brasil. A ave apresentava fraturas em membros pélvicos e asas. Realizou-se radiografias de região celomática, asas e membros pélvicos. Instituiu-se tratamento inicial com aplicação de opioide, anti-inflamatório e analgésico não opioide, bem como manejo nutricional composto por roedor abatido suplementado com complexos multivitamínicos. Após uma semana do tratamento inicial, realizou-se nova radiografia. Devido à consolidação das fraturas de forma assimétrica, decidiu-se realizar a cirurgia de osteotomia. Por se tratar de um caso cirúrgico inédito e em virtude da literatura escassa, este relato apresentou a realização da técnica de osteotomia para correção de fratura patológica em juvenil desta espécie, propondo sugestões em quadros semelhantes e contribuindo para tratamentos de casos graves.

The number of patients with oral lichen planus (OLP) has increased due to the raise of aggressive forms of the disease (erosive, ulcerative and hyperkeratotic forms) with a possible risk of malignancy. There are isolated researches which indicate a genetic determinism to OLP, but more often these conclusions are based on insufficiently adequate and out of date methods, which make it impossible to correctly interpret the obtained data. The aim was to identify a genetical predisposition with a programmed risk to the oral lichen planus. The main group – 278 patients with the OLP (aged 26-65 years). The control group – 298 people (blood donors) who didn’t have dental diseases, as well as diseases of internal organs and systems. The groups were homogeneous by gender and age. In our research we used such methods: clinical, radiological, immunogenetic, statistical methods were used. The erosive form of OLP was associated with 0(I) group in 54.2±0.4% of cases, while the hyperkeratotic form was associated with group 0(I) only in 28.7±1.8% of cases. B(ІІІ) and AB(ІB) groups were less often associated with the erosive form of OLP and were observed in 17.3±0.1% and 2.0±0.1% of cases, respectively. The integration of A(ІІ) group in the erosive form of OLP was 30.5±0.1%, but the indicator was higher than in individuals with B(III) and AB(IV) groups.

The article presents the study results of resiliency modalities and the content of psychoeducational measures for higher education seekers in war conditions. The purpose of the study was to increase the effectiveness and to balance resiliency modalities use by higher education seekers in war conditions while using psycho-educational measures. 174 seekers of higher education were examined, including 144 students of the 4th-6th year of the medical faculty and the faculty of medicine and pharmacy of the Dnipro State Medical University, specializing in 222 «Medicine» (main group) and 30 students of the 4th-5th year of the metallurgical and electro-metallurgical faculties of the Ukrainian State University of Science and Technology (comparison group). A psy­chodiagnostic method using the resource-oriented model of stress resiliency "BASIC Ph" was employed. The first stage involved a statistical analysis of resiliency modalities and their average scores in both groups. In all participants of the main group, it was found that the highest average score was registered in the resiliency modality “Cognitive strategy”. The lowest score was observed for the “Social support” modality. In all participants of the comparison group, it was found that the “Cognitive strategy” modality, as in the main group, had a clear advantage over other modalities, and the lowest score was already observed for the “Emotions” modality. These results formed the basis for creating psychoeducational measures for stress resiliency among higher education seekers in wartime. Psychoeducation for higher education seekers was conducted from September to November 2023, including lectures and individual conversations upon request. The «BASIC Ph» model of stress resiliency was utilized as a framework for determining optimal human resource utilization during crises, with six modalities forming individual style of resiliency. It is crucial to identify dominant modalities and develop those that are less effective. The identified stress resiliency modalities provided a conceptual basis for developing of psychoeducational measures to enhance their effective and balanced use in war situations among higher education seekers. During psychoeducational work with higher education seekers, their resiliency models were analyzed, interpreted, and balanced. Study results should be taken into account in psychological support efforts for higher education seekers in war and post-war time.

At present, managers need to acquire and master various management skills that contribute to a positive organizational environment. The aim of this study is to investigate the association between management skills and the organizational environment of small and medium-sized enterprises (SMEs) in Karachi, Pakistan. The primary objective is to determine how various management skills — negotiation, decision-making, leadership, communication, and teamwork — affect the organizational environment within SMEs. Scientific methods for research adopt a descriptive and quantitative approach, utilizing a questionnaire administered to managers of 253 SMEs. Data analysis was conducted using structural equation modeling (SEM) via the partial least squares (PLS) method, employing SmartPLS 4 software. Findings of the study reveal that the latent variables of negotiation and leadership significantly impact the organizational environment, with an R-square value of 0.854. The effect size (F-square) indicates a high impact of negotiation (F-square = 0.720) on the organizational environment, while leadership has a lower but still significant effect (F-square = 0.103). Other management skills, such as decision-making, communication, and teamwork, also show positive associations with the organizational environment, although to lower degrees. Conclusions. The study emphasizes the significance of management skills, particularly effective negotiation and leadership, in fostering a productive organizational environment in SMEs. Also, it suggests that training and development in these areas could significantly improve performance.

Este procedimiento mínimamente invasivo ofrece múltiples ventajas, como mejores resultados estéticos, menos dolor postoperatorio y una recuperación más rápida. Las indicaciones incluyen colelitiasis, colecistitis aguda y pólipos adenomatosos, mientras que las contraindicaciones abarcan inestabilidad hemodinámica y enfermedades cardiopulmonares graves. La técnica implica la creación de un neumoperitoneo, la inserción de puertos y la disección cuidadosa del triángulo de Calot. La colangiografía intraoperatoria y la ecografía laparoscópica son herramientas útiles para evitar complicaciones. La cirugía puede realizarse incluso durante el embarazo, preferiblemente en el segundo trimestre.
