Solvability of nonlinear coupled system of Urysohn-Volterra quadratic integral equations in generalized Banach Algebras
No full textIn this work, we investigate the solvability of a new class of nonlinear coupled systems of UrysohnVolterra quadratic integral equations involving the generalized fractional kernel functions. By using the LeraySchauder version of the fixed point theorem in the vectorial Banach algebra space, we prove the existence of solutions of the proposed system under suitable conditions. We investigate the stability analysis of the proposed system. Moreover, we establish some special examples and particular cases
SemEval-2020 Task 7: Assessing Humor in Edited News Headlines
No full textThis is the task dataset for SemEval-2020 Task 7: Assessing Humor in Edited News Headlines.
The task’s dataset contains news headlines in which short edits were applied to make them funny, and the funniness of these edited headlines was rated using crowdsourcing. This task includes two subtasks, the first of which is to estimate the funniness of headlines on a humor scale in the interval 0-3. The second subtask is to predict, for a pair of edited versions of the same original headline, which is the funnier version.

Density of Dengue Vector in Hodeidah, Yemen 2017
No full textBackground: Dengue fever is a significant vector-borne disease in tropical and subtropical regions, with Aedes aegypti and Aedes albopictus being the primary vectors. Hodeidah, Yemen, has witnessed increasing dengue cases, necessitated an in-depth analysis of vector density. Objective: This report aimed to investigate the density of dengue vector (Aedes aegypti) in Hodeidah in 2017. Methods: The entomological survey was conducted in Hodeidah Governorate, Yemen in 2017. Data were collected across four seasons—winter, spring, summer, and autumn—through field inspections of mosquito breeding sites. Standard indices, including the House Index (HI), Container Index (CI), and Breteau Index (BI), were calculated based on larval and pupal presence. Environmental parameters such as temperature, humidity, and rainfall were also recorded to assess their correlation with vector density. Results: The entomological survey revealed notable differences in the density of Aedes aegypti between urban and rural districts in Hodeidah Governorate. In urban districts, including Al Hali, Al Hawak, and Al Mina, the mean House Index (HI) was 33.3%, the Container Index (CI) was 17.2%, and the Breteau Index (BI) was 57.23. These levels, while concerning, were significantly lower than those observed in rural districts. In contrast, rural areas showed a higher risk of dengue transmission, with a mean HI of 52.3%, CI of 23.4%, and an alarming BI of 139.9. Several districts such as As Salif, Az Zaydiyah, and Al Qanawis reported BI values exceeding the World Health Organization (WHO) epidemic threshold of 50, reaching up to 330.0 in As Salif. Conclusion : The study revealed a seasonally dynamic trend, with peak infestation observed particularly in autumn and spring. These high values suggest intense but uneven breeding activity across rural settings. The variation in vector indices across districts indicates that while urban areas face persistent risk due to population density and poor sanitation, rural districts may act as hotspots for outbreak initiation due to weak surveillance and inadequate vector control. Coordinated public health action, tailored to local epidemiological and environmental conditions, remains essential to curbing dengue transmission
Adil Baykasoglu and Nabil N.Z. Gindy LOADING FLEXIBLE CELLS: TABU SEARCH BASED SIMULATION OPTIMISATION APPROACH
No full textIn this work a tabu search-based "multi-objective simulation optimisation model " is proposed for loading flexible cell production systems. The problem is formally stated as a goal-programming model hybrid in nature. Some objectives and parameters are determined analytically others are determined from the developed simulation model. The model is solved utilising a tabu search algorithm developed by the author. In the developed methodology parts are assigned to the cells to achieve required performance levels. A capabilitybased approach is used to define processing requirements of products and processing capabilities of production resources. Parts are assigned to cells such that load is balanced between cells and individual production resources within the cells, cell interactions are kept to a minimum, required system performance levels satisfied (when feasible). Example application is provided to explain the developed methodology. 1
Além do paradigma (sobre o legado de thomas kuhn), de nabil araújo (rio de janeiro: Eduerj, 2023)
No full textWith Além do paradigma (Sobre o legado de Thomas Kuhn), “Beyond the Paradigm (On the legacy of Thomas Kuhn)”, Nabil Araújo undertakes a theoretical contribution about the production of knowledge within the University. “Além” (beyond) here, "beyond the paradigm," provides a triple key for reading. First, it is a study "on the legacy of Thomas Kuhn" and his Structure of Scientific Revolutions (1962) in a broad sense, in which the author thinks about the place of the "paradigm" in the conceptual edifice of the historiography of science. In the second sense, "beyond" indicates something of Thomas Kuhn's own position concerning a legacy such as he did not intended it to be his, in his sayings, a legacy arising from the "excessive plasticity" of the word "paradigm." This excessive plasticity, which causes a "loss of control", as Araújo reminds us, however, can be thought of as an surplus-value of the Kuhnian reflection. In this sense, a third "beyond" is performed, produced by the Araújo’s work itself, as he seeks to situate Kuhn's observations towards an opening. What is aimed at is, as the author proposes, "a truly renewed vision of the function of historiography put into play in Structure".Com Além do paradigma (Sobre o legado de Thomas Kuhn), Nabil Araújo empreende uma contribuição teórica sobre a produção de saber no âmbito da Universidade. “Além” aqui, “além do paradigma”, fornece uma tripla chave de leitura. Primeiramente trata-se de um estudo “sobre o legado de Thomas Kuhn” e seu Structure of Scientific Revolutions (1962) em amplo sentido, pensando o lugar do “paradigma” no edifício conceitual da historiografia da ciência. No segundo sentido, “além” indica algo da posição do próprio Thomas Kuhn relativa a um legado como ele não quis que fosse o seu, nos seus dizeres, decorrente da “plasticidade excessiva” da palavra “paradigma”. Essa excessiva plasticidade, que provoca uma “perda de controle”, como Araújo lembra, no entanto, pode ser pensada como mais-valia da reflexão kuhniana. Nesse sentido, um terceiro “além” é performado, produzido pela própria obra, conforme Araújo busca situar as observações de Kuhn no sentido de uma abertura. O que se visa é, como propõe o autor, “uma visão verdadeiramente renovada da função da historiografia colocada em jogo em Structure”
Nanotechnology and Drug Delivery: An Update in Oncology
No full textThe field of nanotechnology has exploded in recent years with diverse arrays of applications. Cancer therapeutics have recently seen benefit from nanotechnology with the approval of some early nanoscale drug delivery systems. A diversity of novel delivery systems are currently under investigation and an array of newly developed, customized particles have reached clinical application. Drug delivery systems have traditionally relied on passive targeting via increased vascular permeability of malignant tissue, known as the enhanced permeability and retention effect (EPR). More recently, there has been an increased use of active targeting by incorporating cell specific ligands such as monoclonal antibodies, lectins, and growth factor receptors. This customizable approach has raised the possibility of drug delivery systems capable of multiple, simultaneous functions, including applications in diagnostics, imaging, and therapy which is paving the way to improved early detection methods, more effective therapy, and better survivorship for cancer patients
