The Immunopathology of Covid-19
Authors: Konduru Pranav , Kethar Jothsna , Appavu, P.h.D. Dr. Rajagopal
Published: March 2024

SARS-CoV-2 is a virus causing Covid-19, with a genome encoding proteins for replication. The innate immune system responds rapidly, employing pattern recognition receptors (PRRs) detecting viral presence. Mucosal tissues offer initial defense, with interferons inhibiting viral replication. Inflammatory cytokines and chemokines attract immune cells, sometimes resulting in cytokine storm. However, excessive inflammation may worsen disease outcomes. The adaptive immune system, comprising CD4+ T cells, CD8+ T cells, and B cells, organize targeted responses. CD4+ T cells activate immune cells and coordinate responses, while CD8+ T cells eliminate infected cells using cytotoxic molecules. B cells produce antibodies that neutralize the virus. Memory B and T cells provide long-term immunity, aiding rapid response upon reinfection. Recovered individuals often exhibit reduced reinfection risks due to memory immunity. Vaccines, like mRNA-based and viral vector-based types, stimulate similar immune responses, bolstering immunity and reducing severe illness.
Modeling Retinoblastoma in adult Drosophila by reducing Rbf gene expression
Authors: Chandarana Pria , Messenger Cathy
Published: March 2024

Retinoblastoma is an eye cancer that begins in the retina due to genetic mutations in the retinal cells, typically of the Rb1 tumor suppressor gene, which encodes for the Rb protein. Rb inhibits the E2F transcription factor, which drives the expression of genes needed for entry into S-phase of the cell cycle. Loss of function of Rb dysregulates E2F, causing uninhibited cell-cycle proliferation and tumor formation. Current treatments for retinoblastoma are highly invasive such as surgery to remove the eye or chemotherapy impacting patients' lives. If an animal model of retinoblastoma is constructed, less invasive therapies can be tested. Drosophila melanogaster have a short life cycle, are cost-effective, and have an Rb1 homologue called Rbf1, making them an efficient model. An RNAi system was used to knock down the expression of Rbf1 protein via the gsGAL4-UAS gene switch system of gene regulation. A fly line in which the gsGAL4 transcription factor is expressed under the eye-specific elav promoter was crossed with a line in which an siRNA targeting Rbf1 mRNA is expressed under the control of an upstream activating sequence (UAS). When the offspring of this cross were fed RU486, the normally cytoplasmic gsGAL4 entered the nucleus of the retinal cells in which it was expressed and bound to the UAS, driving the expression of the siRNA, which was expected to knock down levels of Rbf1 protein in these flies. RU486-treated flies exhibited a change in eye morphology, suggestive of tumor formation, as well as differential Kaplan-Meier survival curves.

Pravno regulisanje prekida trudnoće u komparativnom pravu / Legal Regulation of the Termination of Pregnancy in Comparative Law
Authors: Akšamija Neven
Published: March 2024

This paper explores the legal regulations on the termination of pregnancy in comparative law, a sensitive topic that, although it does represent the exclusive domain of state regulation, encroaches into human rights as well. The basic research question is how selected modern democratic states legally regulate the issue of the termination of pregnancy. Hence, the research goal is to prove that the trend of modern democratic states is to allow the termination of pregnancy even on request, but also to determine the existence of recent retrograde trends in this area. In this paper and research, except for the comparative method, the analytic, dogmatic, normative, and axiological methods are utilized. Although the core of the research is comparative legal, the historic and international legal segments are presented in short in this paper. In researching the following selected states, BiH, Serbia, Croatia, Germany, USA and Ireland, it is determined that the termination of pregnancy is currently largely allowed even on the request of a pregnant woman, especially for justified reasons, with regards to a specific legal regime (Germany), a sudden shift in complete liberalization (Ireland), and even for retrograde changes towards absolute prohibition (USA). In the argument section, the right of the state to ban a medical procedure out of arbitrary reasons (at least in modern discourse) is considered (even disputed). The conclusion is, considering the practice and development of democratic states, the trend of allowing the termination of pregnancy in early stages on demand of a pregnant woman without a reason, and in later stages with a reason, is evident. Concerning the region, the situation is relative satisfactory, although in greater parts of Bosnia and Herzegovina as well as Croatia the outdated legislation needs innovations, as well as certain improvements, which at this point is inevitable.

Using LSTM-Predicted Stock Prices and Risk-Adjusted Performance Metrics to Optimize Portfolios in the European Market
Authors: Martinez-Barbero Xavier , Cervelló-Royo Roberto , Ribal Javier
Published: March 2024

Long short-term memory (LSTM) neural networks allow to capture long-range dependencies and non-linearities in sequential data and can learn complex patterns and relationships in the data improving the accuracy of future stock price predictions. Since classical portfolio optimization is highly sensitive to the estimated parameters used to construct an optimal portfolio, the purpose of our research is to leverage LSTM abilities to predict the parameters accurately and create portfolios that generate superior results.We predict the prices of the 50 components of the EURO STOXX 50® Index using LSTM and create prediction-based optimal portfolios for ten different investment time horizons. We define the risk as a combination of the standard deviation and the performance of the evaluation metrics obtained testing our model, allowing us to use a measure for the risk based on the level of confidence the model has in the prediction.Our portfolios consistently beat the market over the analyzed investment scenarios from 2021 until the first half of 2022 and are robust for both growing and bear markets. The proposed model achieves an average MAE of 0.01634, an average MSE of 0.00047, and an average accuracy of 95.8% in predicting the direction of the stock movements over the ten proposed periods.Our research contributes to the field of finance by providing an innovative framework for portfolio optimization that leverages the power of LSTM-based stock price prediction and risk-adjusted performance metrics.
Data Visualization – The Effect of Graph Animation on Persuasiveness
Authors: Hoffmann Franziska , Sauer Sebastian , González-Ladrón-de-Guevara Fernando
Published: March 2024

To make data visualization more attractive, not just color or different shapes are used, but also animations are nowadays added to graphs. Software tools for data visualization use different representation styles or display features and include animation in the data visualization process. Until now, the positive effect of different representation styles has been taken for granted in practice. However, this raises the question of the extent to which such representation styles are effective and what results can be seen in research in this regard. A literature review on data visualization is given to examine this in more detail. It was considered to what extent there are already findings on whether animated graphs have an effect on consumers’ behaviors. In the following work, we mean by an animated graph, a graph that is not visible from the beginning. Instead, the graph builds up over time. This way, motion is added to the graph. The literature review shows that data visualization has been studied more frequently in some areas. In marketing, this has received less consideration so far. Animations in graphs have not been studied much in the literature.

Published: March 2024

Research into artificial intelligence is not a very young field; its precursors can be traced back as far as the 16th century. Today's technical development, however, is virtually leaping forward, with new intelligent chat systems and social robots playing no small part in this. This is revolutionizing a wide range of scientific and social fields. The very large publication numbers in this field illustrate this as well. In order for academics and scientists to keep track of the discourse in the field, the representatives of the field, the publications as well as the topics and their future development, it is indispensable to prepare these in a bibliometric analysis. Only in this way is it possible to uncover thematic gaps as well as further points of contact and to drive research forward in a targeted and stringent manner. It is precisely this sorting and processing of the research discourse, the topics, and the authors, which is necessary for further research, that is carried out in this paper. For this purpose, using bibliometric analysis tools, an overview of the past, present and future of the research field is created, and the general relevant topics are uncovered. The analysis includes as performance analysis a) the total number of publications and b) the total number of citations, and for science mapping c) a co-citation analysis (past), d) a bibliographic coupling (present) and e) a co-word analysis (future). The data needed for the analysis are identified and extracted from the SCOPUS or Web of Science (ISI) databases.
Recycling of Laboratory Plastic Waste – a Feasibility Study on Cell Culture Flasks
Authors: Martin Annette , Sover Alexandru , Ermster Kathrin , Riess Alisha Klara-Maria
Published: March 2024

Laboratories contribute considerably to the global production of plastic waste. It was estimated that labs involved in biological, medical, and agricultural research produce around 5.5 million tonnes of plastic waste per year (Urbina, M. et al. (2015) Nature 528, 479). Due to chemical and biological contamination, lab plastics pose a challenge for recycling and are most often used as single-use items. After use, these items are waste, and a recycling process or management system is missing. In cell culture, polystyrene (PS) vessels are predominantly used because of their favourable properties, such as transparency, stability, good cell-adhesive properties and biocompatibility.  This paper aims to present the recycling potential of the “laboratory plastic waste” using PS cell culture flasks, after decontamination by autoclaving, as an example. The different steps of the recycling process of the plastic material are presented as well as the biological evaluation of the recycled material. The mechanical and rheological characterization of the recycled PS parts shows a minimal reduction of material quality. The biological evaluation indicates that the recycled material does not meet the requirements of cell culture vessels. Further research is necessary to improve the transparency and surface-cell-adhesion properties of the parts made of the recycled material. Nevertheless, due to the good mechanical properties of the PS recycled material, it can be reused in other applications.
Influence of storage conditions of PVC rooftop sheets on the hot air welding process
Authors: Michalak Martin , Sover Alexandru
Published: March 2024

One of the common welding methods for polymer rooftop sheets is the overlap welding by hot air. For this method two rooftop sheets are put over each other with a certain overlapping part and then a hot air fan, followed by a pressure role is lead through the overlap. The surfaces of the sheets are melted and the pressure of the role bonds them together. This welding method depends on some different parameters to achieve a good welding quality. The main parameters are the welding temperature, the welding speed and the pressure applied to the rooftop sheets. However, as the sheets are used to cover roofs outside, there are a lot of other influences on the weldability of the sheets and the quality of the weld itself. For example, the ambient temperature during the welding process, the intensity of the sun or the humidity of the air. Another influence on which this work is focused, is the effect of the storage temperatures of rooftop sheets. There is no common guideline how storing temperatures effect the welding as producers of rooftop sheets usually only recommend a dry storage. To analyze and characterize this effect, a common PVC rooftop sheet is stored under different temperatures and welded directly after the temperature treatment. The welded samples are tested according to the DIN EN 12317-2 to determine the shear resistance of the weld as it is an important mechanical property and a good indicator for the quality of the weld.
CBL to revitalize deep learning of decision-making methods
Authors: Trull-Domínguez Óscar , Peiró-Signes Ángel , Gómez-Palacios César
Published: March 2024

The use of active methodologies in teaching allows students and teachers a profound change in the way they face the teaching-learning process. The traditional approach where the teacher focuses his effort on the content ceases in favour of a new approach in which the student learns by own experience and decision, reinforcing the deep approach to learning. This is essential for some areas of knowledge, such as decision making. A student cannot face a business decision making if he is not aware of how it works. The use of learning based on challenges, applied to a designed experiential activity, allows the student to feel immersed in the business process, in such a way that they pose their own challenges and thereby develop their learning capacity. The support of virtual technologies like beer factory simulator software, increases this motivation. On this occasion we have designed a simulation activity of a beer bottling factory where students set their own challenges and make decisions according to their objectives, playing inside a virtual factory designed in Factory.io. The article describes the procedures to be able to reproduce this activity, as well as the results obtained in the exercise of the activity.
Real Estate meets technology. The impact of new technologies on the real estate sector in Spain
Authors: Llorca-Ponce Alicia , Rius-Sorollla Gregorio
Published: March 2024

The real estate industry has traditionally been a low-tech industry. The arrival of new, more technological companies in the sector has brought about a revolution in an industry that is very conservative and not very innovative. The term Proptech, short for property technology, groups together new activities that include applications, platforms and, in general, technologies related to the digitalization of the real estate sector. It includes core technologies of the Industrial Revolution 4.0. such as Big Data, Artificial Intelligence, Blockchain, visualization technologies, the Internet of Things and cloud computing; technologies that are rapidly changing how the agents involved, buyers, sellers, investors, managers or tenants, operate. Due to the large number of activities and technologies involved, there needs to be some clarification about the scope of activities and technologies within Proptech. This paper explores the different classifications and maps of Proptech in Spain. The objective is to provide knowledge regarding the composition and delimitation of the Proptech sector in Spain and its comparison with the classifications made in other countries. To do this, an adaptation of the Proptech map of Spain will be made with the categorization created by Baum (2017, 2020) in which four large clusters or groups of activities are identified: Real Estate Fintech, Shared Economy, Smart Real Estate and Data Digitalization and Analytics.
Short foray into the stages of conversion from 2.5D to volumetric printing
Authors: Boca Marius-Andrei , Sover Alexandru , Slătineanu Launrențiu
Published: March 2024

Additive manufacturing gained popularity in the 2000s and is now considered a new or emerging technology of the 21st century. However, the origin of the process is much older and has existed for several decades, more precisely since the 19th century, when it appeared in small science fiction novels. In addition to these layer-by-layer approaches, there are also additive tomographic or volumetric approaches that allow the 3D object to be printed in a single step. These approaches, along with 3D printing of smart materials, are not so popular and consequently not fully understood or utilised. Thus, the paper briefly outlines the history of the transition from classical 2.5D printing, to 3D or non-planar printing, to 4D printing (with smart materials), to 5D printing (on equipment with more than three degrees of freedom), to 6D printing (a combination of 4D and 5D printing) and finally to volumetric printing. The future perspective of this technology are briefly presented with some application and examples.
Generative Agents to support students learning progress
Authors: Schacht Sigurd , Kamath Barkur Sudarshan , Lanquillon Carsten
Published: March 2024

Ongoing assessments in a course are crucial for tracking student performance and progress. However, generating and evaluating tests for each lesson and student can be time-consuming. Existing models for generating and evaluating question-answer pairs have had limited success. In recent years, large language models (LLMs) have become available as a service, offering more intelligent answering and evaluation capabilities. This research aims to leverage LLMs for generating questions, model answers, and evaluations while providing valuable feedback to students and decentralizing the dependency on faculty.We finetune existing LLMs and employ prompt engineering to direct the model toward specific tasks using different generative agents. One agent generates questions, another generates answers, and the third takes the human answers to evaluate and ensure the quality. Human evaluation is conducted through focus group analysis, and student progress and faculty feedback are tracked. Results demonstrate the potential of LLMs to provide automatic feedback and learning progress tracking for both students and faculty.In conclusion, this paper demonstrates the versatility of LLMs for various learning tasks, including question generation, model answer generation, and evaluation, all while providing personalized feedback to students. By identifying and addressing knowledge gaps, LLMs can support continuous evaluation and help students improve their understanding before semester exams. Furthermore, knowledge gaps from students identified by the agent can be highlighted and addressed through additional classes or support materials, potentially generated by the same model, leading to a more personalized learning experience.

En una muestra de 383 animales (121 machos enteros, 129 yeguas y133 castrados) se obtuvieron 16 medidas morfométricas (que incluyeron el peso corporal y dos ángulos articulares, el sacro-coccígeo y el escapulohumeral. La longitud de la grupa apareció correlacionada con estos ángulos. Así pues, en el esquema de selección de la raza de caballo criollo colombiano debería darse una especial importancia a la longitud de la grupa como parámetro condicionador de los ángulos corporales funcionales. Los datos aquí ofrecidos pueden ser de interés si se utilizan para que los criadores, entrenadores y compradores eviten la compra de caballos con potencial limitado debido a graves defectos de conformación.

Aims: The aim of this study is to investigate the reasons for presentation, diagnoses, and outcomes of patients with high fever in the emergency department.
Methods: This research is a retrospective study planned by examining the files and data of patients who presented to the emergency department between 01.03.2021 and 01.03.2023, and whose body temperature was above 38 degrees Celsius. Patient data was analyzed from patient files and the Hospital Information Management System (HIMS). The demographic characteristics, vital signs at admission, reasons for presentation, diagnoses, and outcomes of patients with complete data from patient files and HIMS were investigated.
Results: Of the 288 patients included in the study, 151 (52.4%) were male, and the mean age was 47.04 ± 18.75. When examining the reasons for patients' presentation to the emergency department, 79 (27.4%) patients presented with sore throat, and 44 (15.3%) patients presented with fever. When examining the final diagnoses of patients, acute tonsillopharyngitis was the most common diagnosis with 99 (34.4%) patients, followed by 30 (10.4%) patients with Covid-19. Regarding the outcomes of patients, 190 (66%) patients were discharged from the emergency department, 63 (21.9%) were admitted to the ward, and 26 (9%) were admitted to the intensive care unit.
Conclusion: Cases with high fever in the emergency department encompass a wide range of conditions, ranging from mild viral upper respiratory tract infections to potentially fatal infections such as meningoencephalitis and myocarditis. Therefore, in febrile cases in the emergency department, serious infectious causes should be considered in terms of the focus of fever. Additionally, non-infectious causes should also be kept in mind as they can cause high fever.

The purpose of this study is to investigate the economic impact of the decline in banana exports in the Merka district, Somalia. Bananas and their business constitute the backbone of Somalia's economy, being the second most crucial component after livestock. Various reasons, including the civil war in Somalia and poor security, led banana companies to cease exporting, resulting in a significant economic impact on Somali society. The study employed a descriptive cross-sectional survey approach, distributing a designed questionnaire to the target population comprising 60 banana experts, farmers, economists, and other exporters. The researchers used the Slovenian formula to determine a sample size of 52 individuals and employed a non-probability purposive sampling method. For data analysis, descriptive statistical analysis with mean and standard deviation was conducted using the SPSS application version 16. According to the study's results, the majority of respondents, 69.2 per cent, attributed the fall in banana exports to a lack of security. Similarly, 48.1 per cent of respondents attributed the decline to inappropriate marketing. Additionally, 36.5 per cent of respondents agreed that the lack of infrastructure was the cause, while 42.3 per cent attributed it to the absence of government facilities. I strongly agree with this assessment. Finally, 30.8 per cent of respondents disagreed or strongly disagreed that land conflicts were responsible for the decline in banana exports in Merka, Somalia. The researchers recommended enhancing security in banana plantation areas, modernising existing markets and exploring new ones, incentivising local production and improving infrastructure, particularly roads connecting plantations to markets.
A luta trágica contra o destino: análise genealógica da cultura do empreendedorismo e da desigualdade social
Authors: Vargas Carlos Rafael Hernandez
Published: March 2024

Nas últimas duas décadas, começou a difundir-se uma ideologia pró-empresarial que enfatiza o desenvolvimento de capacidades e o esforço pessoal para estabelecer negócios ou empresas próprias; isso como uma saída diante da degradação das condições de trabalho e do recuo salarial em um amplo espectro de trabalhadores. Esta ideologia, conhecida como "empreendedorismo" ou "empreendimento", reconhece que o salário já não é suficiente para manter um estilo de vida individual ou familiar digno. Por isso, promove a ruptura com a condição de empregado, desenvolvendo habilidades mínimas de administração, utilizando a criatividade e, acima de tudo, assumindo o trabalho com entusiasmo e muita vontade, com o objetivo de criar "seu próprio negócio" além de beneficiar a sociedade. No entanto, economistas como Stiglitz (2015), Piketty (2015), Esquivel (2016), entre outros, chamaram a atenção para o fato de que para superar as condições econômicas desfavoráveis, geradas pela desigualdade própria do capitalismo do século XXI, é necessário mais do que entusiasmo e vontade. Neste artigo, analisa-se a ideologia do empreendedorismo sob uma ótica genealógica, bem como da antropologia filosófica, mostrando a continuidade desta com todo o discurso do burguês como um herói e do empresário como o self-made-man.
