Authors: Malakar Prafull , Leeladharan M
Published: June 2024

ICT applications streamlined processes across multiple industries and improved efficiency at a lower cost.Although everyone is generally in favor of this, many people view the development of artificial intelligence as both a blessing and a threat. It is unquestionably widely utilized in academic settings for experimentation and concept articulation, but with so many possibilities available, students and researchers find it difficult to select the best one. This study attempts to evaluate seven generative AI content creation tools—Writesonic, Jasper, Grammarly Business, ProWritingAid, Scalenut, Rytr, and TextCortex AI-using data from the GetApp website. Employing content analysis, the seven selected tools were compared on the basis of qualitative data converted to binary format. Grammarly Business led with a score of (76), followed by Scalenut (75), Writesonic (53), ProWritingAid (51), Jasper (48), TextCortex AI (38), and Rytr (36). This study highlights the pivotal role of collaboration in generative AI, showcasing diverse features, from grammar checks to creative content generation. The significance of this study lies in aiding academia and professionals in strategic tool selection, emphasising the need for informed decision-making in collaborative efforts. Integrating Artificial Intelligence and Natural Language Processing enhances scholarly endeavours, underlining the necessity for efficient content creation during digital evolution.

Authors: Bonelo-Ayala Yonathan , Benítez-Mojica David , Muñoz-Posso Jhovanny
Published: June 2024

Este artículo presenta un nuevo resultado de geometría euclidiana que involucra los baricentros de un triángulo y los triángulos formados modificando un vértice del triángulo anterior por su reflexión axial con respecto a una recta dada. Estos baricentros son colineales, y la recta que los contiene es perpendicular a la recta inicial sobre la cual se consideraron las reflexiones axiales. Adicionalmente, se suministra una generalización del teorema mencionado para cuadriláteros y se detallan las demostraciones formales de ambos resultados. Esto se presenta siguiendo los pasos para la construcción de conjeturas de Benítez Mojica y Santos-Trigo, utilizando ambientes de geometría dinámica que se puedan emplear en experiencias futuras en cursos de geometría euclidiana con ayuda de nuevas tecnologías.
Entrepreneurship in the Age of Social Media
Authors: MacCrory Frank , Macharia Mary , Ravindran Kiron , Vithayathil Joseph
Published: June 2024

Social media is ubiquitous and continuously evolving. This study investigates the impact of social media on the intention toward entrepreneurship/self-employment. Further, we explore the moderating effect of social media on the relationships between women, self-efficacy and leisure activities on intention toward entrepreneurship/self-employment using a survey-based dataset. We find that the ability to take advantage of social media within an entrepreneurial context does not necessarily mean that an individual is propelled towards entrepreneurship, however proactive individuals are able to exhibit this characteristic, as are creative women. A counter-intuitive finding is that entrepreneurship and conventional organizational employment choices are not mutually exclusive. While risk aversion inhibits entrepreneurship as expected, contextual conditions such as being married or being employed affects men and women differently.
Axion-electrodynamics and the Poynting theorem
Authors: Bruce Stanley A.
Published: June 2024

In a recent study, we proposed an axion-electrodynamics model that consistently incorporates a lepton Dirac field into the gauge-invariant Lagrangian of a closed physical system. Our investigation delved toward potential applications of the model, with a focus on its implications in the realm of Dark Matter axions interacting with leptons in a nonlinear electrodynamics background. In the present work, we introduce an extended axion-electrodynamics model wherein the Bianchi identities are modified by the axion field. This leads to a modification of the energy conservation law for the fields: the Poynting theorem in a source-free region, in which the axion field is involved. By implementing a quantization scheme, our model can offer a novel approach for addressing the problem of axion production/conversion in the presence of electromagnetic and Dirac fields.
A hazai civil szervezetek társadalmi megítélésének egyes dimenziói
Authors: Erdélyi Tea , Szabó Katalin
Published: June 2024

A TANULMÁNY CÉLJA
A huszadik század végére a témával foglalkozó szerzők (egyebek mellett) a termékek és szolgáltatásokat és a társadalmi felelősségvállalást is a vállalati hírnév fontos tényezőjeként tartották számon. Felmerül azonban a kérdés, hogy hogyan alakulnak a hírnevet befolyásoló tényezők az olyan szervezetek esetén, ahol a társadalmi felelősségvállalás maga a szolgáltatás? Különösen érdekes ez a kérdés a hazai civil szervezetek esetén, amelyek rendszerváltás utáni alakulásába az állam és a nyugati civil szerveztek is jelentősen beleszóltak, speciális helyzetet teremtve ezzel az ágazatban. Napjainkra az ismertség és a jó hírnév gyakran a civil szervezet túlélésének biztosítéka. Jelen tanulmány célja ezért egyrészt feltárni a hazai civil szervezetek jó hírének egyik fontos dimenziója, az ismertség alakulását egyes civil szervezetek esetén. Másrészt megvizsgálni azt, hogy mennyire van összhangban a szervezetek és az érdekgazdák véleménye a hírnevet meghatározó tényezőkről.
ALKALMAZOTT MÓDSZERTAN
Jelen tanulmányban nyolc szervezeti interjú és egy százfős, véletlenszerű, nem reprezentatív mintán végzett survey eredményei alapján keresünk választ a fenti kérdésekre. A szervezeti interjúk a kérdőív előkészítését, pontosítását segítették. A kérdőíves felmérés tizennégy olyan hazai civil szervezet ismertségét és jó hírnevét vizsgálta, több dimenzió mentén, amelyek kevéssé népszerű társadalmi témákkal foglalkoznak.
LEGFONTOSABB EREDMÉNYEK
A kutatás jelen tanulmányban ismertetett, első része két hipotézist vizsgál: egyrészt, hogy (H1) a társadalmi szervezetek jó hírének legfontosabb tényezői a hitelesség, a jó minőségű szolgáltatás, illetve a munkáltatói brand. Noha ezt a hipotézist csak részben sikerült igazolni, a fejlemények számos tanulsággal szolgálhatnak a civil szervezetek számára. A láthatóság kapcsán hipotézisünk: (H2) a kutatásba bevont civil szervezeteket többen vélik ismerni, mint ahányan valóban ismerik. A kutatás a vélt és valós ismertség között nem talált szignifikáns eltérést.
GYAKORLATI JAVASLATOK
A hírnévtényezők közül a szervezetek az átláthatóságnak, a közreműködők motiváltságának, az ismertségnek és a kommunikációnak az érdekgazdáknál kisebb jelentőséget tulajdonítanak. Ez a civilek számára fontos tanulsággal szolgálhat a fejlesztéshez, hiszen az érdekgazdák a potenciális önkénteseik és támogatóik, így érdemes lehet a véleményüket figyelembe venni.
Immediate Interventional Management of Aortocoronary Dissection During PCI: A Case Report
Authors: Kalvachev Nikolay , Valkov Veselin , Dragnev Nikolay
Published: June 2024

Aortocoronary dissection is a rare and potentially fatal complication of percutaneous coronary intervention. It is more common when performing interventions of the right coronary artery or during revascularization of chronic total occlusions. Here, we aimed to provide more data regarding a less common form of this complication. We present the case of an 81-year old woman admitted with an acute infero-lateral myocardial infarction, who was indicated for emergency primary coronary intervention. After revascularization of the left circumflex artery, the left main coronary artery exhibited retrograde dissection into the ascending aorta. This complication was managed with immediate placement of another coronary stent at the left main coronary artery. Further propagation of the dissection was prevented. The patient was discharged in good health with antiagregant and rhythm control therapy for new onset atrial fibrillation. Although retrograde dissection of the left main coronary artery is a very rare complication, it can be successfully managed interventionally.
Increased capacity to maintain glucose homeostasis in a transgenic mouse expressing human but not mouse growth hormone with developing high-fat diet-related insulin resistance, hepatic steatosis and adipose dysfunction

Published: June 2024

The objective was to assess the potential differential effects of human versus mouse growth hormone in vivo, given that human unlike mouse growth hormone can bind prolactin as well as the growth hormone receptor. To this end, a transgenic CD-1 mouse expressing human but not mouse growth hormone was generated, and the phenotypes of male mice fed with a regular chow or high-fat diet were assessed. Pancreas and epididymal white adipose tissue gene expression and/or related function were targeted as the pancreas responds to both prolactin and growth hormone receptor signaling, and catabolic effects like lipolytic activity are more directly attributable to growth hormone and growth hormone receptor signaling. The resulting human growth hormone-expressing mice are smaller than wild-type CD-1 mice, despite higher body fat and larger adipocytes, but both mouse types grow at the same rate with similar bone densities. Unlike wild-type mice, there was no significant delay in glucose clearance in human growth hormone-expressing mice when assessed at 8 versus 24 weeks on a high-fat diet. However, both mouse types showed signs of hepatic steatosis that correlated with elevated prolactin but not growth hormone RNA levels. The larger adipocytes in human growth hormone-expressing mice were associated with modified leptin (higher) and adiponectin (lower) RNA levels. Thus, while limited to observations in the male, the human growth hormone-expressing mice exhibit signs of growth hormone insufficiency and adipocyte dysfunction as well as an initial resistance to the negative effects of high-fat diet on glucose clearance.
FERTILITY CARE IN LOW AND MIDDLE INCOME COUNTRIES: Fertility care in low- and middle-income countries
Authors: Ombelet Willem , Lopes Federica
Published: June 2024

Infertility affects millions worldwide, with significant medical, financial, and emotional challenges, particularly in low- and middle-income countries (LMICs). Cultural, religious, financial, and gender-related barriers hinder access to treatment, exacerbating social and economic consequences, especially for women. Despite its prevalence, infertility often remains overlooked due to competing health priorities. However, global initiatives recognise infertility as a reproductive health concern, advocating for universal access to high-quality fertility care. In LMICs, limited resources and infrastructure impede access to treatment, prompting people to turn to alternative, often ineffective, non-biomedical solutions. Addressing these challenges requires implementing affordable fertility care services tailored to local contexts, supported by political commitment and community engagement. Emerging technologies offer promising solutions, but comprehensive education and training programs are essential for their effective implementation. By integrating fertility care into broader health policies and fostering partnerships, we can ensure equitable access to infertility treatment and support reproductive health worldwide.

Published: June 2024

Dental anomalies (DAs) in children refer to conditions affecting the structure, number, shape, and size of teeth. This study aimed to assess the prevalence of these anomalies in both primary and permanent dentitions among two Mexican pediatric populations aged 2-14 years. Additionally, the level of knowledge about DAs among students pursuing a degree in dentistry in both universities was determined. A cross‑sectional study was conducted on children making their first visit to the Pediatric Dental Clinics of the Universities of Nuevo León and San Luis Potosí in México between March and May 2017. The prevalence of DAs was estimated. In addition, a questionnaire comprising 20 closed items regarding DAs was administered to 100 undergraduate students to evaluate their level of knowledge. Ninety-four children (54 boys and 42 girls; mean age 9.73±2.1 years) were included. Twenty-two patients (23.4%) exhibited at least one DA in their primary or permanent teeth. The most common DAs were in size (macrodontia) and structure (enamel hypoplasia). Agenesis occurred three times, and there were two cases of mesiodens. Regarding gender, 10 patients were girls (45.4%), and 12 were boys (54.6%). The prevalence of DAs in permanent teeth (57.5%) was higher than that in primary teeth (42.5%, p=0.031). Only two patients presented DAs in both primary and permanent teeth. No tooth-shaped anomalies were detected. Regarding the level of knowledge among the university students, the percentage of correct answers was 61.6%. Our findings emphasize the importance of encouraging parents to initiate pediatric dental visits early. Additionally, the study highlights the significance of conducting a thorough evaluation of the patients.

The Influence of Perceptions on Fisherman Understanding and Fish Traders and Management Strategies of Sharks and Rays in Conservation Status in Cilacap Regency
Authors: Rianto Joko , Riani Etty , Warlina Lina
Published: June 2024

Cilacap Regency is one of the giant Shark and ray landing sites on the south coast of Java. Engagement in fisheries management, such as RFMOs and CITES, requires regulations governing the use of sharks and rays in Indonesia. The successful application of these rules requires the support of fishermen and fish traders. The aim of the study was to determine the effect of the perceptions of fishermen and fish traders on the understanding of the management status of sharks and rays and management strategies. The research method uses a quantitative approach, instrument testing, and simple linear regression data analysis using SPSS 25 software. The Shark and Ray management strategy uses SWOT analysis. The results of the average social, economic interval (fisherman) level assessment were 2.27 (enough), perceptions of environmentally friendly fishing gear were 3.11 (good), perceptions of the existence of shark and ray resources were 2.52 (good), and the value of understanding indicators supported management of sharks and rays 2.27 (fairly understand). Assessment of social-economic indicators (fish traders) and perceptions 2.53 (good), perceptions of the existence of shark and ray resources 2.17 (adequate), and understanding in supporting shark and ray management 2.43 (comprehensive). The results of simple linear regression show that fishermen's socioeconomic indicators have a negative effect on understanding supporting Shark and ray management. Fishermen's perceptions of environmentally sound fishing gear, perceptions of the existence of shark and ray resources (fishermen and fish traders), and the socioeconomic conditions of fish traders have no influence on understanding supporting sharks and rays. The results of the SWOT analysis are in the Weakness and Opportunity cells, namely through efforts to limit products, increase the human resource capacity of business actors and related agencies, and ease of obtaining access to capital for fishermen.

Published: June 2024

The increase in aquaculture activities has made most people interested in working on it. Catfish is one of the cultivation commodities that are in great demand by the public. This study aims to analyze the growth of probiotic catfish (Clarias sp.) in soil ponds with the KJT system. The research was conducted from September to November 2022 at the pond of Mr. Fitra, a member of the Pokdakan Mina Berkah Mandiri, Balunijuk Village, Bangka Belitung. The research method includes calculating the growth of catfish and testing water quality which is accompanied by PP No. 22 years 2021. Fish growth shows a positive allometric pattern, meaning that weight growth is more dominant than length growth. This is thought to be a positive effect of the probiotic Probio_FmUBB on catfish growth and pond water quality. Water quality is sufficient to support the growth of catfish, especially the main parameters such as temperature, pH, and DO. Known water quality values such as temperature parameters 27-30oC, pH 6.05, and DO 5.03 mg/L affect catfish growth. Feeding full pellets is very supportive of positive allometric growth patterns and optimal catfish growth. Suggestions can be developed for catfish enlargement by Pokdakan with persistence while raising fish.

Published: June 2024

Purse seine is a type of fishing gear that has the principle of catching fish by circling a school of fish. Fish caught by purse seine include lemuru, skipjack, and tuna (pelagic fish), which have economic value. One area where the majority of fishermen use purse seines is PPS Kendari. The more fishermen use the purse seine, the more it will affect the income or feasibility of the fishing business. The feasibility status of the business can be identified by conducting a business analysis of the fishing activity. Business analysis begins with participating in a trip to one of the purse seine fishing activities at PPS Kendari in January-May 2020. Carry out business-related recording activities (business capital, maintenance, and income). After the data is obtained, a business analysis will be carried out on the profit value, profit sharing system, R/C ratio, and payback period (PP). Based on the business analysis that has been done, the total cost of fishing activities is Rp. 212,716,600.00, and the company made a profit of Rp. 1,074,353,400.00. profit-sharing system, with each share amounting to Rp. 20,270,818.87. So, it can be said that fishing using purse seines at PPS Kendari is still feasible, with a value of 6.05 and a PP of 0.61 years.
‘I didn’t know they could one-shot me!’
Authors: Burnett Heather , Loder Matthew Iver
Published: June 2024

This article presents a corpus study spanning 11 years (2011–2022) of language referring to Gwyndolin, a boss in the videogame Dark Souls. Like many aspects of Dark Souls, Gwyndolin’s gender is open to interpretation, and this study tracks how both players’ readings of Gwyndolin’s gender and the pronouns they use to refer to Gwyndolin have changed over the past decade. The results show that, while players overwhelmingly read Gwyndolin as a cis man and use the pronoun ‘he’, there have been significant increases in trans and nonbinary interpretations, as well as the use of ‘they’ after 2015. The observed patterns can be linked to social changes inside and outside videogame culture occurring around 2014–2016. The study provides valuable real-time support for the existence of a change in the pronoun system (and its relation to trans/nonbinary identities), which had previously only been proposed on the basis of apparent-time data.

Footprints on the beach: visualising dilation-induced air entry
Authors: Parera Morales F. , Siemens G. A. , Mckellar M. , Pinyol N. M. , Alonso E. E. , Take W. A.
Published: June 2024

The dry fringe that appears beneath a footprint on a beach is a visual manifestation of dilation. Dilation causes the sand to attempt to increase in volume on shearing, resulting in negative pore pressure and enhanced bearing capacity. Conventional theory cannot explain this increase in strength, suggesting instead that bearing capacity with the phreatic surface at the sand surface should be approximately half that of the dry case. To explore this apparent contradiction, ten load-controlled bearing capacity experiments were performed on transparent soil with phreatic surfaces ranging from 100 mm below to 30 mm above the footing. For phreatic surfaces deeper than the footing width, failure occurred within the dry material. In shallower phreatic surface conditions, bearing capacity increased as the phreatic surface approached the surface. Air entry was observed to initiate along the top surface of the saturated layer and extend to the depth of the bearing capacity mechanism. For the case of the phreatic and soil surfaces being coincident, the bearing capacity was observed to be more than double that of the dry case. In submerged cases bearing capacity was less than values at the surface, as there was no air–fluid interface to enhance the development of negative pore pressure.
Fair Enough? Mini-Public Composition and Outcome Acceptance from the Maxi Public
Authors: Paulis Emilien , Pilet Jean-Benoit , Rojon Sebastien , Vittori Davide
Published: June 2024

One hope associated with the spread of deliberative mini-publics in established democracies is that they could increase acceptance of policies because of their inclusive and diverse composition. Yet, participants are not representative of the broader public in all characteristics. They tend to be more engaged with politics or debated policy issues than the average population. Building on a Climate Citizens’ Assembly commissioned by the Luxembourg government in 2022 (Klima Biergerrot-KBR), this study examines how the maxi public reacts when informed about the profile of mini-public participants. Via a survey experiment, we found that descriptive representation and similarity matter to accept the outcomes, but not universally. It depends on respondents’ attitudes about mini-publics prior to the experiment and situations of cognitive dissonance. Indeed, when people initially neutral or opposed to mini-publics (‘participatory skeptics’) learn that the process is fairly representing (their in-) groups, they increase their willingness to accept the outcomes, stressing improvement in the perceived legitimacy. By contrast, the lack of social inclusion and political diversity is an issue to keep the ‘participatory enthusiasts’ on board, stressing that they also pay attention (and perhaps even more) to how and which groups of citizens are represented within a mini-public. Our message is that deliberative mini-publics need to address more thoroughly how they can best meet their normative assumptions of participatory equality and procedural fairness; otherwise, they may not help to foster political legitimacy.
ЭФФЕКТИВНОСТЬ ПРОВЕДЕНИЯ МОНИТОРИНГА КАК ИНСТРУМЕНТА ВЫЯВЛЕНИЯ СТЕПЕНИ ДЕГРАДАЦИИ ЦЕННЫХ ЗЕМЕЛЬ
Authors: Долматова Людмила Георгиевна
Published: June 2024

Целью исследования является анализ вопросов проведения мониторинга ценных земель для своевременного выявления процессов деградации, происходящих под воздействием антропогенных и природных факторов.
Методологическую базу исследования представляют базисные положения в области проведения работ по мониторингу земель и повышению их эффективности как важного инструмента выявления всех видов деградации, которым подвержены земли сельскохозяйственного назначения, под воздействием целого ряда антропогенных и природных факторов. Методологические положения в области обследования качества земель позволят более дифференцированно подойти к подбору сельскохозяйственных культур, проведению почвозащитных мероприятий в разных районах Ростовской области. К используемым научным методам относятся причинно-следственный, сравнительный и системный анализ, метод логических взаимосвязей.
Результаты исследования. В результате всестороннего анализа особенностей проведения работ по мониторингу земель было выявлено, что для рациональной организации территории и производства любого сельскохозяйственного предприятия необходимо максимально учесть все свойства земельных участков, в том числе их качество и степень деградации. Для изучения реально сложившейся ситуации важно своевременно проводить обследовательские работы, позволяющие оценить степень почворазрушающих процессов и ареалы их распространения. Исследование показало, что в Ростовской области водной эрозией охвачены в основном северные районы, а ветровой — южные и восточные районы. На территории данных районов процессы эрозии распространяются из-за высокой освоенности земель сельскохозяйственного назначения, т. е. интенсивного земледелия, плохого состояния полезащитных и водорегулирующих лесных полос, высокой антропогенной нагрузки. Также практически повсеместно имеют место процессы дегумификации почв. Для устранения негативных последствий деградации земель в Ростовской области предусматривается оказание государственной поддержки из областного бюджета, что будет способствовать улучшению ситуации в вопросах восстановления ценных территорий.
Перспективы исследования заключаются в важности проведения мониторинга земель и обследования территорий, в наибольшей мере подвергшихся почворазрушающим процессам. Своевременное выявление степени и наиболее преобладающих видов деградации ценных земель позволит принять меры по их устранению в районах Ростовской области и как следствие — увеличить урожайности культур, повысить уровень и эффективность сельскохозяйственного производства хозяйствующих субъектов.

Investigating and Measuring Radon Gas Concentration in Tehran and Alborz Metro Stations
Authors: Yavarian Fakhraldin , Soltani Jamshid , Khorshidi Abdollah
Published: June 2024

Humans are regularly exposed to various types of radioactive radiation and, of course, to Radon-222 over the course of their lives. According to the report of the United Nations scientific committee on the effects of atomic radiation in 2000, the average human is estimated to be exposed to about 4.2 mSv of radioactive radiation each year, 52% of which is caused by inhalation of radon gas. The radon gas is one of the most important elements that is emitted from the decay of natural uranium and radium in the earth. Therefore, the concentration of this gas can be higher in enclosed spaces, especially underground locations, and it is important to measure the amount of radon gas radiation in these underground stations. In this research, a domestically manufactured environmental meter for radon gas was used to measure the concentration of this gas in different Tehran metro stations. In general, all 42 subway stations of Tehran and Karaj cities were measured at continuous time intervals during the spring season. On average, trace amounts of radon gas were observed in all the stations, but high concentrations of radon gas were measured at some stations, such as Tajrish and Ghaem stations in the northern Tehran-Karaj plain due to underground water resources, fault type and distinct geological structures. According to the US Environmental Protection Agency (EPA) standard, the maximum permissible amount of radon gas concentration in the air is 148 Bq/m3, while the average amount was 156 Bq/m3 at Tajrish station. This amount is above the permissible limit and can therefore be considered hazardous to health. Geologically, the Meydan-e-Azadi (Azadi square) station on line 4 located in the center of Tehran also revealed a near high radon concentration due to bedrock that it mainly has been consisted of calcite. Consequently, measures for better ventilation and easier air movement are required in such stations.

Authors: Sierra Gallego Germán , Echavarría Adriana , Palacio Luz Amparo
Published: June 2024

The mineral Libethenite Cu2 (PO4 )(OH) was prepared through hydrothermal reaction under milder conditions than those previously reported. The product was characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA) and atomic absorption (AA). The crystal data were determined by X-ray crystallographic studies, which can be summarized as follows: space group Pnnm, a = 8,071(2), b = 8,403(4), c = 5,898(3) Å, V = 399 Å3 and Z = 4. Thermal analysis and X-ray diffraction studies showed that the solid is stable up to 580 oC. At higher temperatures the Libetinita decomposes in Cu4 O(PO4 )2 and water.
Numerical solution of biological reaction diffusion models on fixed domains by the finite element method
Authors: Vanegas Juan Carlos , González Libardo Andrés , Garzón Diego Alexander
Published: June 2024

Several biological phenomena have been described using mathematical models based on reaction diffusion equations. The solution of this type of equations gives rise to formation of spatial-temporal patterns, in agreement with the biological reality of the simulated phenomenon. This article describes the numerical implementation of a set of three well-known reaction diffusion models: the morphogenesis Schnakenberg model, and the GiererMeinhardt and Thomas reaction kinetics models. The aim is to analyze the set of parameters associated with the spatial-temporal pattern formation. The numerical implementation was performed using the finite element method in one dimensional and two dimensional domains. It was concluded that spatialtemporal pattern formation in reaction diffusion models depends on the constant parameters of the model, the initial conditions and the implementation technique. The analysis of these dependences is useful in the formulation and validation of new mathematical models describing biological phenomena.

A geometrical approach for surface reconstruction by means of radial basis functions with compact support
Authors: Torres-Sánchez Germán , Branch John William
Published: June 2024

Recently in the community of computer vision related with the surface reconstruction processes of free-form objects there has been a growing trend in the use of interpolation techniques. In this area the radial basis functions interpolator can produce three-dimensional models with high levels of precision, high flexibility to reproduce complex shapes and a high tolerance to noise level. The radial basis functions used for data interpolation need to estimate a set of parameters. This work shows a approach to estimation of those parameters based on the surface geometric characteristics, these are both centers and support ratio. The approach results are shown mean by interpolation of real objects range data.

On the Question of Admissibility of Certain Methods in Forensic Linguistic Examination
Authors: Lebedeva A. K.
Published: June 2024

The article raises the question of the criteria of admissibility of the use of certain methods in forensic linguistic examination. Despite the methodology of forensic linguistic examination that has been worked out over the years, some specialists prefer to use extremely controversial methods, for example, such as the method of associative experiment and phonosemantic analysis. These methods do not meet the criteria required by forensic expertology, which leads to the expert exceeding the limits of his/her competence, as well as to serious expert mistakes.
Together Apart: the Influence of Increased Crowd Heterogeneity on Crowd Dynamics at Bottlenecks
Authors: Geoerg Paul , Boomers Ann Katrin , Berthiaume Maxine , Boltes Maik , Kinateder Max
Published: June 2024

Individual differences in mobility (e.g., due to wheelchair use) are often ignored in the prediction of crowd movement. Consequently, engineering tools cannot fully describe the impact of vulnerable populations on egress performance. To contribute to closing this gap, we performed laboratory experiments with 25 pedestrians with varying mobility profiles. The control condition comprised only participants without any additional equipment; in the luggage condition and the wheelchair condition, two participants at the center of the group either carried suitcases or used a wheelchair. We found that individuals using wheelchairs and to a lesser degree those carrying luggage needed longer to pass through the bottleneck, which also affected those walking behind them. This led to slower times to fully clear the bottleneck in the wheelchair and luggage condition compared to the control group. The results challenge the status quo in existing approaches to calculating egress performance and other key performance metrics in crowd dynamics.
