Most Probable Dynamics of the Single-Species with Allee Effect under Jump-Diffusion Noise
Authors: Tesfay Almaz , Yuan Shenglan , Tesfay Daniel , Brannan James
Published: September 2023

We investigate the most probable phase portrait (MPPP) of a stochastic single-species model with the Alleeeffect using the non-local Fokker-Planck equation (FPE). This stochastic model is driven by non-Gaussianas well as Gaussian noise. It has three fixed points in the deterministic case. One of them is the unstablestate which lies between the two stable equilibria. We focus on the transition pathways from the extinctionstate to the upper fixed stable state for the transcription factor activator in a single-species model. This helpsus to study the biological behavior of species. The most probable path is obtained from the solution of thenon-local Fokker-Planck equation corresponding to the population system of the single-species model, andthe corresponding maximum possible stable equilibrium state is determined. We also acquire the Onsager-Machlup function for the stochastic model and solve the corresponding most probable paths. The numericalsimulation manifests that: (i) When non-Gaussian noise is presented in the system, the maximum of thestationary density function is located at the most probable stable equilibrium state; (ii) If the initial valueincreases from extinction state to the upper stable state, the most probable trajectory goes to the maximallikely equilibrium state, in our case it lies between 9 and 10; (iii) The most probable paths increase to stablestate quickly, then maintain a nearly constant level, and approach to the upper stable equilibrium state astime goes on. These numerical experiment findings accelerate growth for further experimental study, inorder to achieve good knowledge about dynamical systems in biology.

Authors: Qin Dan , Li Fan , Yang Jian
Published: September 2023

Background: This study used SEM to investigate pharmacovigilance knowledge, attitudes, and practices among healthcare personnel and the public in Yunnan Province and explored the relationships between them. Demographic characteristics were also examined for their impact on knowledge, attitudes, and practices. The study aims to inform the development of policies and education programs aimed at improving pharmacovigilance.
Methods: This cross-sectional study used a survey design, with healthcare personnel and the public in Yunnan Province as the research subjects, and data were collected using a questionnaire survey. Data analysis and statistical description were performed using SPSS 27.0, and structural equation modeling (SEM) was constructed and analyzed using AMOS 26.0.
Results: This study collected 209 public questionnaires and 823 healthcare personnel questionnaires. The public's average pharmacovigilance knowledge score was 4.62±2.70, with a total awareness rate of 57.75%, an average attitude score of 31.99±4.72, a total holding rate of 91.40%, and an average behavior score of 12.07±4.96, with a total execution rate of 75.44%. The average pharmacovigilance knowledge score of healthcare personnel was 4.38±3.06, with a total awareness rate of 87.60%; the average attitude score was 27.95±3.34, with a total holding rate of 93.17%; and the average behavior score was 7.75±2.77, with a total execution rate of 77.50%. Both public and healthcare personnel KAP models showed a significant positive correlation between pharmacovigilance knowledge, attitude, and behavior. Demographic characteristics had no statistical significance on public pharmacovigilance knowledge, attitude, and behavior, while they had a positive impact on healthcare personnel's pharmacovigilance knowledge, attitude, and behavior, except for gender.
Conclusion: This study revealed that the current status of pharmacovigilance knowledge, attitude, and behavior among healthcare personnel and the public in Yunnan Province is not optimistic, with significant differences between the two groups. The SEM results show that there is a significant positive correlation between knowledge, attitude, and behavior, and demographic factors such as age, occupation, and highest education level have an impact on the KAP of pharmacovigilance. Therefore, it is necessary to strengthen pharmacovigilance education, improve the public's awareness and understanding of pharmacovigilance, and promote the reasonable and safe use of drugs.

Purpose:
Manifestations of emotion in social conversational interactions stand at a focal point in the rapidly growing affective computing area, with applications in healthcare, education and human-computer interaction. Artificial intelligence (AI) holds great potential in modelling the challenging dynamic nature of affect in speech conversation. In this paper, we analyze and criticize latest trends and open problems through a systematic review and multi-subgroup meta-analysis of AI approaches for emotion recognition in conversation (ERC).
Methods:
We adopt the PRISMA-DTA guidelines toward analysis of AI-driven speech ERC. A comprehensive database search through predefined query strings and selection criteria allowed for data extraction of essential diagnostic performance parameters. We analyze salient patterns related to methodological quality and risk of bias. Univariate random-effects models are then designed with a multi-subgroup perspective, centered around affective annotations models, while encompassing the ERC parameters of modalities, feature extraction and conversation style.
Results:
51 studies were systematically reviewed for qualitative analysis, whereas 27 articles were included in the meta-analysis. Diagnostic test performance manifested with high heterogeneity, with intriguing insights regarding affective state annotation, input modality, feature extraction methods, and dataset conversation style.
Conclusion:
Our research contributes fine-grained insights as recommendations that tackle open-problems in ERC. While providing valuable information on diagnostic performance of AI in speech ERC, we underscore the imperative need for further advancements in annotations and models capable of handling diverse emotional expressions.
Application of Maximum Overlap Discrete Wavelet Transform and Machine Learning to Improved Daily Rainfall Prediction Modeling
Authors: KÜLLAHCI Kübra , ALTUNKAYNAK Abdüsselam
Published: September 2023

Rainfall is an important phenomenon for various aspects of human life and the environment. Accurate prediction of rainfall is crucial for a wide range of sectors, including agriculture, water resources management, energy production, disaster management, and many more. The ability to predict rainfall in an accurate fashion enables stakeholders to make informed decisions and take necessary actions to mitigate the impacts of natural disasters, water scarcity, and other issues related to rainfall. In addition, advances in rainfall prediction technologies have the potential to contribute to sustainable water management and the preservation of water resources by providing the necessary information for decision-makers to plan and implement effective water management strategies. Hence, it is important to continuously improve the accuracy of rainfall prediction. In this paper, the integration of the Maximum Overlap Discrete Wavelet Transform (MODWT) and machine learning algorithms for daily rainfall prediction is proposed. The main objective of this study is to investigate the potential of combining MODWT with various machine-learning algorithms to increase the accuracy of rainfall prediction and extend the forecast time horizon to three days. In addition, the performances of the proposed hybrid models are contrasted with the models hybridized with commonly used discrete wavelet transform (DWT) algorithms in the literature. For this, daily rainfall raw data from 3 rainfall observation stations located in Türkiye are used. The results show that the proposed hybrid MODWT models can effectively improve the accuracy of precipitation forecasting, based on model evaluation measures such as mean square error (MSE) and Nash-Sutcliffe coefficient of efficiency (CE). Accordingly, it can be concluded that the integration of MODWT and machine learning algorithms have the potential to revolutionize the field of daily rainfall prediction.

Authors: Sun Zhaochen , Xiang Dan , Jiang Junyan , 陈 一天
Published: September 2023

Heart metastasis in cervical cancer is an exceptionally uncommon occurrence. Given the early onset of obscure clinical presentations and complex imaging features of cardiac tumors, cases diagnosed before death are exceedingly rare. In this report, we present a case of cervical cancer with cardiac tumor metastasis diagnosed pre-mortem, and conducted a review of the current literature. The following conclusions were drawn: (1) The incidence of cardiac metastasis is influenced by clinical stage and treatment modality at initial diagnosis. (2) The prognosis for patients with cervical cancer heart metastasis is poor, and those with severe complications struggle to accrue benefits from active treatment. (3) When cervical cancer patients present with unexplained dyspnea, cardiac color ultrasound and enhanced chest CT should be performed to rule out tumor cardiac metastasis.

Risk assessment of breast cancer (BC) seeks to enhance individualized screening and prevention strategies. Recent deep learning (DL) risk models based on mammography have shown superiority in short-term risk prediction compared to traditional risk factor-based models. However, these models primarily rely on single-time exams, which emphasize the detection of existing lesions and may ignore the temporal changes in breast tissues. In this study, we present the Multi-Time Point Breast Cancer Risk Model (MTP-BCR), a novel temporospatial DL risk model that integrates traditional BC risk factors and longitudinal mammography data to identify subtle changes in breast tissue indicative of future malignancy. Utilizing a large inhouse dataset comprising risk factors and 171,168 mammograms involving 9,133 women, we evaluate the performance of the MTP-BCR model in long-term risk prediction. Our model demonstrates a significant improvement in 10-year risk prediction with an area under the receiver operating characteristics (AUC) of 0.80, outperforming the traditional BCSC 10-year risk model, our pure image model (without risk factors), and is also superior to other SOTA methods at 5-year AUC in various screening cohorts. Furthermore, MTP-BCR provides unilateral breast-level predictions with AUCs up to 0.81 and 0.77 for 5-year and 10-year risk assessments, respectively. External validation in the public CSAW-CC dataset demonstrates the consistent advantage of our multi-time point-based model compared to the single-time point-based method. For the prediction of breast cancer recurrence, our MTP-BCR obtains a 5-year AUC of 0.71 which also surpasses other methods. The heatmaps derived from our model may help clinicians better understand the progression from normal tissue to cancerous growth, enhancing interpretability in breast cancer risk assessment.

Background: Previous epidemiological studies have shown that the triglyceride-glucose index (Ty-G) was well- known predictor for the development of diabetes mellitus. A study proposed that traditional lipid ratios, particularly the TGHDL- C ratio based on the proportion between pro atherogenic and anti-atherogenic fractions are more effective than single lipids measure in identifying IR. Ty-G index predicted the subsequent occurrence of HTN in a positive and dose-dependent manner. Therefore, early detection of the Ty-G index may be beneficial for early interventions to prevent HTN among the Chinese population Methodology: The present study was an observational study and the results of total 128 hypertensive patients and healthy volunteers aged between 35 to 60 years was collected from a Tertiary care hospital. Body mass index (BMI), Waist Circumference (WC), blood pressure, fasting blood glucose and Triglyceride levels were measured. Receiver Operating Characteristic (ROC) Curve was used to check association between the study groups. Results: ROC curve based on sensitivity and specificity with reference to TyG-BMI as dependent variable among the groups. Area under curve for Waist/Hip ratio(W/H) was 0.543, HbA1c was 0.766, albumin/creatinine was 0.512, aspartate aminotransferase/alanine aminotransferase was 0.528, triacylglycerol/high density lipoprotein was 0.681 with cut-off value of W/H is 0.81, HbA1c is 5.05, albumin/creatinine is 2.56, AST/ALT is 0.41, TAG/HDL is 0.71 respectively. TyG-WC as dependent variable in normotensive and hypertensive subjects, area under curve for W/H was 0.626, HbA1c was 0.671, albumin/creatinine was 0.527, AST/ALT was 0.528, TAG/HDL was 0.681 with cut-off value of W/H ratio is 0.80, HbA1c is 5.05, albumin/creatinine is 2.56, AST/ALT is 0.55, TAG/HDL is 1.64 respectively. Conclusion: Our observational study suggests that higher Ty-G index was associated with higher probabilities of hypertension in general adult population. Large-scale prospective cohort studies are looked-for to elucidate the latent pathophysiological mechanisms underlying the association among Ty-G index and hypertensive subjects.

This paper introduces the concept of lattices of prime fuzzy ideals, which extends the classical theory of lattices of prime ideals in ring theory to the fuzzy setting. In this paper, we propose some examples and properties related to lattices of prime fuzzy ideals, contributing to the knowledge in fuzzy algebra. Think about an ordered semigroup â„›. Plotting the function f from â„› to the closed interval [0,1] defines a fuzzy subset of â„›, where [0,1] Ïµ â„›. In order to explore prime ideals in rings, semigroups, and ordered semigroups in terms of fuzzy subsets, we build an ordered semigroup â„› with ordered fuzzy points. To study, we presented the thoughts of â„’-fuzzy prime ideals of an ordered semigroups â„›, which forms a completelattice obeying the law relating the operations of multiplication and addition.

Published: September 2023

This paper delves into the intricate relationship between justice, just measurement, and the Islamic worldview. It explores how the concept of justice in Islam extends beyond mere convenience, gaining spiritual significance with the advent of the religion. Precise measurements play a vital role in various acts of devotion, from determining prayer directions to calculating times for obligatory and non-obligatory rituals. The paper also discusses Islamic perspective on life as a series of tests, where evaluation and measurement are pivotal. The accumulation of deeds, intentions, and actions is meticulously recorded, serving as both incentives and deterrents. The consequences of these measures are experienced in the Hereafter, influencing ones eternal fate.Self-evaluation is highlighted as a means of measuring ones own faith and deeds, ultimately promoting self-improvement. Justice is portrayed as a central moral precept, tied to prosperity, faith expression, and moral excellence. The Quran is referred to as the ultimate measure for upholding morality.This discussion emphasizes the significance of just measurement in various contexts, including economics, governance, and educational assessment. The importance of moral measurement and judgment throughout history is discussed, aligning with Islamic principles and promoting excellence in society.In conclusion, this paper underscores the ethical obligation of applying just measurements and evaluations, rooted in the principles of Islam and methods of validity, to promote justice and moral integrity in various aspects of life.

Authors: Negese Solomon Ayele , Kebede Habtamu Hailu
Published: September 2023

Adequate and sustainable supply of potable water in urban areas of developing countries is often a challenge. This study assessed the performance of the water supply system in Muke Turi town, Oromia, Ethiopia. The Water Geospatial Engineering Modeling System (WaterGEMS) model was used for hydraulic analysis of the distribution network. The water losses were determined by different indicators including non-revenue water (NRW), losses per pipe connection (LPC), losses per main pipe length (LMPL), unavoidable annual real losses (UARL), and infrastructure leakage index (ILI). The water supply coverage of the town was found as 43.34%, which is considerably low. From the hydraulic analysis, the velocity of flow in 54.2% of the pipe and pressure at 60% of the nodes were found within the recommended ranges. The NRW was estimated at 37.61%, which is above the acceptable limit. Of which, the real losses are the major ones with 37.14%. Moreover, the LPC and LMPL were found to be 298 l/d and 29,709 l/km/d, respectively, which are again above the recommended limits. Based on ILI, the annual real losses were estimated to be 4.31 times the UARL. Finally, it was concluded that access to water in the town is inadequate which is exacerbated by high losses.

Published: September 2023

En la región andina la ganadería se sustenta en la alimentación de pastos naturales, los mismos que dependen de las lluvias para su crecimiento y producción. Su pobre calidad y bajo rendimiento redundan negativamente en los índices productivos del ganado. Una alternativa, a esta problemática, es la introducción de pastos mejorados y permanentes de buen valor nutritivo y de mayor rendimiento; es por ello que se realizó el presente trabajo con el objetivo de evaluar las características agronómicas y productivas de tres variedades de alfalfa, en sierra central, con el fin de seleccionar la de mejor desempeño. El área experimental fue de 198 m2 (11 m x 18 m) donde se establecieron 96 m2 de alfalfa correspondientes a tres parcelas de 32 m2 cada una (4 m x 8 m) separadas entre sí por 1,5 m. Se empleó el diseño experimental completamente al azar con tres tratamientos (variedades WL350, WL450 y Hortus401) y ocho repeticiones por tratamiento. Las variables evaluadas fueron: altura de planta (AP), rendimiento de forraje verde fresco (FV) y de materia seca (MS) y la tasa de crecimiento (TC). WL350, WL450 y Hortus401 alcanzaron alturas de 30,25; 32,75 y 23,5 cm y materia seca de 2 258, 2 714 y 1 813 kg ha-1 corte-1, respectivamente (p<0.05). La variedad WL450 mostró mayor tasa de crecimiento (22,31 kg MS ha-1 día-1) respecto a las otras dos variedades. Se concluye que las tres variedades tuvieron buen comportamiento productivo de forraje. WL450 fue la variedad de alfalfa de mejor rendimiento para las condiciones del sitio de evaluación.

Authors: Dutra Giselle Bezerra Mesquita , Gomes Adriana Leite Limaverde
Published: September 2023

Como parte de uma pesquisa de Mestrado em Educação, analisamos os aspectos conceituais do letramento midiático (BUCKINGHAM, 2010) em notícias de três edições de um jornal escolar, produzidas, ao longo de 2017, por um grupo de estudantes dos anos finais do ensino fundamental, conhecido como Clube do Jornal, em uma escola pública de Fortaleza – CE. A análise das notícias revela que esse gênero representa vivências no contexto socioeconômico dos estudantes, materializadas em uma linguagem escrita com fragilidades quanto à norma padrão, embora eles mantenham objetividade no gênero e desenvolvam recursos linguísticos adequados de estilo. Em acréscimo, as notícias ressaltam narrativas convencionais do universo escolar, visto que a audiência principal são os leitores da própria instituição. Portanto, os estudantes acabam convergindo para um letramento midiático mais endógeno e intuitivo, com características do letramento escolar, uma vez que falta uma maior assessoria pedagógica ao Clube.

Considerando a atual conjuntura educacional dos sujeitos surdos, principalmente os inúmeros aspectos pertinentes à representação da escrita, verificamos que, por não receberem estímulos adequados ao seu potencial cognitivo, socioafetivo, linguístico e político-cultural, muitos desses estudantes têm sofrido perdas consideráveis no desenvolvimento da aprendizagem. Posto isso, este estudo visa contribuir para a compreensão de fatores que concorrem para a difícil relação do surdo com o desenvolvimento de produção de texto na escola com o objetivo de cooperar para o processo de alfabetização, levando em conta suas dificuldades e perspectivas. O enfoque da pesquisa é de ordem teórico-conceitual, por centrar-se na (re)construção de conceitos, ideias e ideologias necessários ao aprimoramento dos fundamentos teóricos já desenvolvidos sobre a temática. Os dados obtidos na investigação revelam que a dificuldade que o surdo enfrenta ao produzir textos escritos na escola está para além das metodologias e/ou ações pedagógicas empregadas no ensino da língua escrita.

Este artigo analisa as práticas educativas utilizadas por professoras de Língua Portuguesa, mais especificamente relacionadas sobre as práticas de multiletramentos, abrangendo a cultura digital nos processos educativos. A metodologia abrangeu revisão bibliográfica de estudos que tratam das perspectivas dos multiletramentos e da cultura digital. Como instrumento de coleta de dados, foram realizados cinco encontros virtuais, com quatro professoras de Língua Portuguesa, que atuam em redes públicas estaduais de ensino no estado de São Paulo, com o objetivo de realizar o processo de escuta de suas narrativas sobre suas experiências com multiletramentos. Os resultados apontaram que a escola, com base nessas escutas de relatos de professores, precisa reavaliar seus processos pedagógicos no ensino de Língua Portuguesa, incluindo suas novas demandas sociais, que interferem nas linguagens e, sobretudo, nas práticas educativas e sociais.

The article aim is to identify mean values and change trends in the frequency of winds that pose a danger to navigation on shipping routes of the Laptev and East Siberian Seas which became evident in 2010–2021 period. In the period under review the winds were considered dangerous if their average hourly speed over the water surface at 10 m altitude exceeded 15 m/s. The factual material is based on information from the ERA5 global reanalysis. The research methodology involves the use of standard methods of mathematical statistics. A comparative analysis of the last two 12-year periods (1998–2009 and 2010–2021) has shown that the climate changes that happened in 2010–2021 significantly affected the wind regime of the studied region, which had consequences for shipping. In August, a significant decrease in the frequency of dangerous winds was recorded in the region, which generally contributed to the improvement of navigation safety by reducing storm risks. Opposite trends manifested themselves from September to December, which led to increased storm surge and a rise in the likelihood of ships icing, especially on the high-latitude paths of the Northern Sea Route and approaches to the Long Strait. The decrease in the frequency of winds, revealed in January and April, contributed to the preservation of a stable ice cover and stable difficult navigation conditions in these months. The persistence of the identified trends in interannual changes in the wind regime in the region under consideration in the future is not guaranteed. Therefore, the development of the existing network of Arctic weather stations remains an urgent problem for shipping.

Due to the new concept of the country transport logistics development “Turning to the East”, it is becoming the more important to increase the processing capacity of container terminals in the Far East. This research work is to study the possibilities of increasing the throughput capacity of container terminal areas by making the technical and technological management decisions. The opportunity of introducing automation elements into the terminal operation through the creation of a technological cyclic automatic machine on the basis of mobile container transporters is investigated as an idea to increase the processing capacity of the terminal equipment. In the context of developing the concept of the loader operation as a technological machine, the “working cycle” term is defined as a sequence of actions during performing the technological operation of picking up the target container from the stack, and then the transition diagram of the machine is an analogue of the technological scheme of this operation. Based on the foregoing, the purpose of the study is defined as the rationale for choosing a unified scheme for the technological operation of dismantling the container stack as part of automating the working cycle of a loader. To achieve this purpose, the following tasks are solved: the technical capabilities of loaders such as a reach stacker and a loader with an upper grip spreader are studied when working with a stack depending on the location of the target container in the latter; technological schemes for the execution of the operation of picking up target containers from a stack, differing in the type of equipment used and the method of disbanding blocking stacks, are considered; the positive and negative aspects of using each of the technological schemes as an analogue of the transition diagram of the technological machine control unit are revealed. The result of the research work is the technological scheme “the use of a reach stacker or a loader with a top grip spreader with complete disassembly of blocking stacks and picking up containers only from the near row”, which is the most preferable in terms of such important indicators for automating the technological process as versatility, “trouble-free” execution technology, insensitivity to stack capacity.

Timely implementation of maintenance processes provides confidence in maintaining performance and integrity throughout the life cycle of the system. Various developments in monitoring and analysis methods are aimed at maintaining the operability of systems by minimizing the failure rate. The developed computer program, presented in the paper, is used as one of the tools for assessing the technical condition of a ship power plant, allowing the use of an integrated approach to predicting and managing the quality of maintenance, including an assessment of the costs and timing of the implementation of repair work. When describing the creation of a computer program for assessing the structural integrity of ship engine elements, special attention is paid to the libraries used and the methods necessary for a comprehensive consideration of the “oil-engine” system. The Makava program, based on laboratory analyzes, allows you to determine the residual life of engine oil according to the actual state, by determining the parameters that mainly affect its aging, wherein setting threshold values for these parameters, forms the degree of deviation of actual values from the boundary values, predicting further wear of certain elements of the system. The program contains a database of typical changes in oil indicators regarding the occurrence of possible structural defects in the elements of the system, helps to expand the information resource by collecting, processing, accumulating and storing information on the degradation of the components of the propulsion complex of various engine models for subsequent planning of measures for the quality of maintenance and repair of shipboard power installations.
Medical diagnosis and its nature

Diagnosis is one of the most important concepts in medicine, the correctness of which determines in many respects the success of treatment, prevention and, ultimately, the quality and life expectancy of the patient. Currently, in medical science and practice, there is a great diversity both in understanding the essence and form of a medical diagnosis, and in approaches to its establishment. However, in the practice of doctors, what is formulated as a diagnosis does not even meet the basic requirements for this concept. We have made an attempt to bring to a common denominator both the theoretical understanding of the diagnosis and the forms of its implementation in practice, to scientifically substantiate the definition of diagnosis and diagnosis, to strictly define its subject, content, boundaries and forms in order to increase the effectiveness of prevention and treatment of diseases on the way to achieving the main goal of medicine to improve the quality and increase the life expectancy of the patient.

Objective: to study the prevalence of vitamin D level disorders in therapeutic patients and the features of their correction. Materials and methods: 322 patients who applied for medical help in the field of therapy («rheumatology» and «cardiology») were examined. Materilas and methods: clinical, laboratory (study of the level of vitamin D in the blood), statistical. Results: it was found, that among patients with a therapeutic profile, vitamin D concentration disorders (deficiency and insufficiency) occur in 72.7% of the surveyed. There is a high prevalence of risk factors for osteoporosis in the examined patients: female sex prevails (81%), age (average age was 53.6 ±14.3 years), drug use (50% take proton pump inhibitors, 21.4% take glucocorticoids). When comparing the proportion of people with impaired vitamin D levels in comparison with the data of previous years, there was a decrease in the proportion of people with vitamin D deficiency and an increase in the proportion of people with vitamin D deficiency. Among people with a vitamin D level of 30-100 ng/ml, daily use of vitamin D preparations in dosages exceeding the recommended consumption levels was noted. Conclusion: based on the data obtained, the prevalence of vitamin D deficiency and insufficiency remains high. However, recently there has been a trend towards a decrease in the proportion of people with vitamin D deficiency and an increase in the proportion of people with vitamin D deficiency. In this connection, it is necessary to inform the population about the recommended adequate levels of vitamin D in blood serum and safe dosages of vitamin D preparations for daily intake.
