Authors: Amaral Fernando Henrique Nogueira , Lavor Otávio Paulino
Published: September 2023

Esta intervenção, efetuada em uma turma do 2º ano do ensino médio, tem como objetivo compreender o desenvolvimento de uma Sequência Didática no processo de ensino e aprendizagem de conjuntos numéricos e noção de funções, função afim, função quadrática e função exponencial, mediado pelas ferramentas tecnológicas GeoGebra e o programa de criação/edição de apresentações gráficas PowerPoint. Para tanto, abordamos uma Sequência Didática contendo três fases, em que a primeira se tratou da apresentação da proposta para a turma participante da pesquisa, e a efetivação de um pré-teste. A fase posterior foi dividida em atividades contendo três módulos, nomeados de módulo 1, módulo 2 e módulo 3. A última fase, designada de pós-teste, buscou investigar a aprendizagem nesses conteúdos expostos. A pesquisa ocorreu em uma escola estadual da rede pública de ensino na cidade de Rafael Godeiro, no Rio Grande do Norte, composta por vinte alunos. Para os testes, pré-teste e pós-teste, utilizamos dois questionários, em que o primeiro possuía seis questões de múltipla escolha e, o segundo, sete questões discursivas. Os resultados apontam, a partir das análises do pré-teste e pós-teste, que o ensino por meio da Sequência Didática mostrou-se facilitador e animador no processo de ensino e aprendizagem da Matemática. Tais resultados ficam evidentes após a análise do pós-teste, que foi efetuado após toda a Sequência Didática. Com isso, o trabalho desperta os educadores, além de uma abordagem diferenciada do ensino tradicional, uma reflexão para que se aplique situações didáticas para o ensino sobre conjuntos numéricos e funções mediadas pela utilização de recursos tecnológicos que incentivem cada vez mais os educandos.

Published: September 2023

Em meados de 2020 o mundo foi surpreendido com um novo modo de vida em decorrência da pandemia do Coronavírus. As escolas e as universidades tiveram que suspender suas atividades de modo a evitar aglomerações e conter a proliferação do vírus, sendo, então, decidido que as aulas aconteceriam em formato remoto, que foi chamado de Ensino Remoto Emergencial (ERE). Desta forma, as Tecnologias Digitais de Informação e Comunicação (TDIC) tornaram-se o principal meio de suporte para a continuação dos estudos. Dentre os recursos utilizados pelos docentes nas aulas online destaca-se o uso do vídeo em diferentes modos. Pensando nisso, essa pesquisa tem como objetivo compreender, junto aos docentes do Curso de Licenciatura em Matemática da Universidade Estadual Vale do Acaraú (UVA), como se deu a utilização dos vídeos durante o período do ERE. Para tanto, aplicou-se um questionário para o referido público contendo ao todo cinco perguntas, no intuito de identificar desde os equipamentos e softwares utilizados até o uso e/ou produção de vídeos. Buscou-se, também, fazer um paralelo com os resultados apresentados pelo Relatório de Pesquisa do Comitê de Enfrentamento à Pandemia de Coronavírus da UVA, o qual objetivava, dentre outras coisas, compreender as condições de acesso à Internet e a equipamentos eletrônicos por parte de toda a comunidade universitária. Pôde-se perceber o quão importante foi o uso de recursos digitais, sejam mídias ou TDIC, na ministração de aulas no período de distanciamento social provocado pela pandemia de Coronavírus, corroborando, assim, a importância e expansão desse uso nos dias atuais. Atestou-se que a maioria dos docentes do Curso de Licenciatura em Matemática da UVA utilizou vídeos como recurso para promoção da aprendizagem dos estudantes e que a utilização das TDIC, em específico as videoaulas, em um curso de graduação no período remoto, foi muito importante para a formação docente, uma vez que proporcionou aos licenciandos a oportunidade de conhecer diferentes ferramentas tecnológicas que tanto foram utilizadas como recursos para aprendizagem como também potenciais ferramentas de ensino de matemática.

Authors: Santos Róbson Lousa , Oliveira Aline Alves de
Published: September 2023

As operações fundamentais da aritmética estão presentes no cotidiano das pessoas que têm uma forma específica de realizá-las, seja por meio de ferramentas eletrônicas, por meio de cálculos mentais ou com o auxílio de papel e caneta utilizando algoritmos muitas vezes ensinados na escola ou fora dela. Entretanto, tradicionalmente, a escola tem ensinado algoritmos específicos para cada uma das operações fundamentais e muitas vezes outros algoritmos não apenas não são ensinados, como também o seu uso é desestimulado. Este trabalho tem como principal objetivo investigar como estudantes da EJA têm aprendido e utilizado as operações fundamentais da aritmética fora da escola, bem como quais técnicas utilizam. Além disso, busca-se entender qualitativamente o quão significativo e efetivo tem sido a aprendizagem dos algoritmos de operações fundamentais na escola. Para isso, o estudo foi embasado na coletânea Na vida dez, na escola zero (CARRAHER, CARRAHER, SCHLIEMANN, 1995), recorrendo à combinação do método clínico-piagetiano com a observação participante. Foi observado a recorrência do uso dos algoritmos aprendidos na escola ao se fazer cálculos mentais durante atividades cotidianas como compras em supermercados observando-se assim a grande familiaridade dos participantes com as técnicas escolares.

Authors:   Ivan Franko National University of Lviv, Pytel-Huta Sophia
Published: September 2023

Background. The article presents data obtained as a result of our research on the territory of Rivne Nature Reserve during 2018–2022. We collected 118 individuals belon­ging to 43 species, 19 genera from the Crabronidae, Sphecidae, Scoliidae, and Pompilidae families. The captured insects fed on 12 plant species belonging to eight families. A preliminary list of wasp species of the studied families that occur on the territory of Rivne Nature Reserve is presented. The studied individuals are stored in the entomological collections of the Zoological Museum of Ivan Franko National University of Lviv. The aim of the research was to prepare a preliminary list of wasp species of Rivne Nature Reserve and to identify their trophic relationships with angiosperms. Material and Methods. The object of the research was the wasps of the Crabronidae, Sphecidae, Scoliidae, and Pompilidae families. Insects were caught by an entomological net using the method of selective catching directly on plants to identify their trophic relationships. Konus Crystal 7x-45x binoculars (Konus, Italy) and specialized keys and descriptions were used to identify the insects. Identification of angiosperms was carried out with the help of special keys. Results. We collected 43 species of wasps belonging to 19 genera (Bembix, Cerceris, Crabro, Crossocerus, Ectemnius, Lestica, Nysson, Oxybelus, Gorytes, Pemphredon, Tachysphex, Ammophila, Sceliphron, Scolia, Priocnemis, Anoplius, Arachnospila, Episyron, and Dipogon). Most of the wasps (40 species) were registered on the territory of Rivne Nature Reserve for the first time. We identified trophic relationships between the adults of 27 wasp species and plants belonging to 12 genera. The publication provides a preliminary list of the species from the territory of Rivne Nature Reserve. The individuals are stored in the collections of the Zoological Museum of Lviv University. Conclusions. Out of 43 species (19 genera) of wasps, 40 were recorded for the first time in Rivne Nature Reserve. These include Sceliphron curvatum, which is invasive in Europe.Trophic relationships of 27 adult wasp species with 12 angiosperm species were established. As a result, a preliminary list of wasp species for the territory of Rivne Nature Reserve was prepared and trophic relationships of some representatives of the families Crabronidae, Sphecidae, Scoliidae, and Pompilidae with angiosperms were revealed.

Published: September 2023

Background. Two species of water frogs, Pelophylax ridibundus and Pelophylax lessonae, and their hybrid, Pelophylax kl. esculentus, are widespread in Ukraine. The purpose of this study was to investigate the population structure of various types of hemiclonal population systems (HPS) of water frogs formed due to the coexistence of frogs in the same territory. In Ukraine, a hybridization centre with the spread of triploid individuals of hybrid nature has been identified. Triploid hybrids are an intriguing research subject due to the diverse hypotheses about their origin and role in HPS. Outside the hybridization centre in Kharkiv Region, triploids are not commonly found. In our study, we describe the initial findings of triploid specimens in Lviv Region and analyze the genetic structure of the HPS where such individuals were detected. Methods. In total, 193 specimens of green frogs were collected between 2011 and 2015. Here we present population structure analysis which was conducted using two microsatellite loci, Rrid059A and RlCA1b5. A wide range of software programs were utilized for processing the genetic analysis data, including GenePop 4.7.5, Micro-Checker and NewHybrids 1.1. Results. Three types of hemiclonal population systems were identified: R-E type in Perekalky and Lake Pisochne, L-E type in Lake Luky, and R-E-L type in Nyzhankovychi, Velykyi Lyubin, Zhovtantsi and Cholgyni. Additionally, population systems with hybrids of mixed ploidy (diploids and triploids) were found in Perekalky, Velykyi Lyubin and Zhovtantsi. Conclusions. Genetic diversity analysis revealed variations in the number of alleles per population. P. ridibundus individuals exhibited higher genetic diversity compared to P. lessonae individuals, whereas hybrids showed intermediate genetic diversity. Further investigations of the localities where potential triploids were detected are necessary to assess the survival and reproductive potential of hybrid individuals and determine all types of hybrids and individuals of both marsh and pool frogs.

Authors: GÜNDÜZ Cemil , ATAK Onur
Published: September 2023

Tourism, as a booming industry, plays a significant role in shaping economies and cultural exchanges worldwide. However, the rapid growth of tourism has brought about both positive economic impacts and negative environmental consequences. This research delves into the environmental effects of tourism activities through the lens of sustainable tourism. Focusing on Niksar Çamiçi Plateau, a transition zone between Central Anatolia and the Black Sea Region, situated at an altitude of 1350 meters, the study aims to identify the specific environmental impacts resulting from tourism activities in this unique location. The research adopts participant observation and semi-structured interviews as data collection methods, enabling a comprehensive understanding of tourists’ and locals’ behaviors and practices concerning the environment. The findings highlight the pressing issues of unplanned development, urban sprawl, migration, and environmental pollution in regions experiencing concentrated tourism activities. In response to these challenges, the study proposes a set of sustainable tourism solutions to mitigate environmental degradation. Recommendations include promoting responsible tourism practices, reducing the carbon footprint, promoting environmentally friendly accommodation and transportation, and implementing effective waste management strategies. Additionally, raising awareness among tourists and local communities about the importance of preserving natural resources and cultural heritage emerges as a crucial approach. This study contributes to the growing body of knowledge on sustainable tourism by providing valuable insights into the complex relationship between tourism and the environment, particularly in Niksar Çamiçi Plateau. By advocating for sustainable practices, the research aims to strike a balance between economic growth and environmental conservation, ensuring a harmonious coexistence between tourism and the ecosystem.

Published: September 2023

Ethics consultations are often needed at difficult junctures of medical care. However, data on the nature of how patient characteristics, including race/ethnicity, language, and diagnosis, affect ethics consult outcomes are lacking. We performed a retrospective cohort study of all patients who were seen by the Ethics Consult Service between 2017 and 2021 at a large tertiary academic center with the aim of determining whether patient demographic and clinical factors were associated with the timing of ethics consult requests and recommendations of the ethics team. We found that patients admitted for COVID-19 had significantly longer median times to consult from admission compared with other primary diagnoses (19 vs. 8 days respectively, p=0.015). Spanish-speaking patients had longer median times to consult from admission compared to English speaking patients (20 vs 7 days respectively, p=0.008), indicating that language barriers may play a role in the timing of ethics consultation. This study demonstrates the need to consider clinical and demographic features when planning and prioritizing ethics consultations at large institutions to enhance consult efficiency, resource utilization, and patient experience and autonomy.
TMEM165 is differentially expressed in central nervous system metastasis in human breast cancer.
Authors: Mamoor Shahan
Published: September 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that transmembrane protein 165, encoded by TMEM165, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. TMEM165 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of TMEM165 in primary tumors was correlated with patient overall and recurrence-free survival. Modulation of TMEM165 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

Mapping the Open-Source Response to Covid-19: Growth, Interactions, and Impact
Authors: Keogh Colin
Published: September 2023

The COVID-19 pandemic necessitated rapid innovation to address emergent healthcare challenges, spotlighting the open-source community's role in fostering collaborative solutions. This study explores the engagement dynamics within this community by analysing keyword mentions across academic databases, GitHub, and Google search from January 2020 to December 2022. Findings reveal a wave-based engagement pattern with spikes in mentions and search interest during critical pandemic junctures, particularly around ventilators, masks, and personal protective equipment. A challenge in maintaining heightened engagement post the peak of each wave was observed, reflecting the evolving focus of the crisis. The study also noted a shift in focus within the open-source community from ventilators to other healthcare necessities as the pandemic unfolded. These findings underscore the potential of open-source initiatives in fostering agile solutions amidst evolving crisis landscapes. The results advocate for strengthened engagement between policymakers, public health organisations, and the open-source community to align with real-world healthcare needs, augmenting the potential for innovative solutions during future crises. This study illuminates the significance of open-source paradigms as resilient frameworks for navigating complex healthcare challenges and underscores the value of collaborative, transparent, and innovative approaches in addressing global health exigencies.
Categorizing Dog’s Real World Visual Environment
Authors: Pelgrim Madeline Helmer , Raman Shreyas Sundara , Serre Thomas , Buchsbaum Daphna
Published: September 2023

Dogs have a unique evolutionary relationship with humans yet little is known about the visual information available to them or how they direct their visual attention within their environment. The present study, inspired by comparable work in infants, classified the items available to be gazed at by dogs during a common daily event, a walk. We then explored the statistics over the availability of those categories and over the dogs’ visual attention. Using a head-mounted eye-tracking apparatus that was custom designed for dogs, 11 dogs walked on a pre-determined route outdoors under naturalistic conditions generating a total of 11,698 gazes for analysis. Image stills from these fixations were analyzed using computer vision techniques to explore the items present, the space within the visual field those items occupied, and which of the items the dog was gazing at. On average dogs looked proportionally most at buses, plants, people, the pavement, and construction equipment, however there were significant individual differences. The results of this project provide a foundational step towards understanding how dogs look at and interact with their physical world, opening up avenues for future research into how they learn and make decisions, both independently and with a human social partner.

Прогнозування вартості історичної холодної зброї
Authors:   Державний торговельно-економічний університет, КАРАВАЄВ Тарас
Published: September 2023

Питання оцінки пам’яток культури, в тому числі оцінки втрат, завданих україн­ським музеям, архівам, фондам та приват­ним колекціонерам внаслідок військової агресії рф, є актуальним і вкрай важливим для власників та розпорядників. Воно пов’я­зане з необхідністю визначення оцінної вартості в численних судових справах про втрачене, пошкоджене чи викрадене майно, а також правомірності передання майнових прав та визначення страхових сум. Для товарознавчої оцінки професійним оціню­вачам, судовим експертам потрібні об’єк­тивні, уніфіковані та комп’ютеризовані методи розпізнавання культурних пам’яток, зокрема холодної зброї, для їх подальшої оцінки. Це дає змогу використати наявні інформаційні джерела і спеціалізовані бази даних для виявлення й оцінки спорідненості об’єктів експертизи, прорахувати приблизну оцінну вартість зразків холодної зброї. Актуальності набуває розроблення спе­ціалізованого алгоритму визначання вар­тості втрачених та знищених культурних цінностей, зокрема і холодної зброї. Оскільки експертам і колекціонерам важко сформувати вартість лотів з урахуванням постійної зміни та безсистемності інфор­мації про антикварну холодну зброю, завдан­ням дослідження є удосконалення методики, що принаймні частково розв’яже описану вище проблему. Результатом проведеного дослідження є удосконалена методика з проведення оцінки холодної зброї, яка значно спростить проце­дури оцінювання лотів аукціонів та пред­метів музейних і приватних колекцій.

W szczególności zbadano, w jakich sytuacjach wydanie takiej decyzji jest niezbędne do przeprowadzenia prac budowlanych i w jakim zakresie inwestor może korzystać z cudzej nieruchomości. Celem artykułu było  zbadanie czy obecnie obowiązujące przepisy nie stanowią nadmiernej ingerencji w prawo własności umożliwiając udzielenie zgody w formie decyzji administracyjnej na wejście na teren cudzej nieruchomości. O ile ustalono, że obecne regulacje nie dokonują nadmiernej ingerencji w prawo własności to jednak ustawodawca nie sprecyzował sposobu naprawnienia szkody powstałej w wyniku korzystania inwestora z cudzej nieruchomości (budynku, lokalu) odsyłając w tym zakresie do kodeksu cywilnego. Taka konstrukcja może powodować, że właściciel nieruchomości będzie musiał sam podjąć często kosztowne i długotrwałe starania w tym zakresie na drodze cywilnoprawnej.

Published: September 2023

W ostatnich latach zyskał na sile postulat ujednolicenia dolnej granicy wieku odpowiedzialności karnej i górnej granicy wieku obrony obligatoryjnej. Celem niniejszego artykułu jest ocena zasadności rzeczonego postulatu. Przeprowadzona analiza wykracza poza ramy prawa i postępowania karnego i nawiązuje również do prawa cywilnego w szczególności w zakresie zdolności do czynności prawnych oraz zdolności deliktowej. W badaniach uwzględniono psychologiczne ujęcie zdolności nieletniego oraz praktyczne doświadczenia z funkcjonowania nieletniego w postępowaniach przed sądem.
Czy niestawiennictwo do odbycia czynnej służby wojskowej jest występkiem trwałym?
Authors: Kulik Marek
Published: September 2023

Celem pracy jest dokonanie oceny charakteru prawnego przestępstwa niestawiennictwa do odbywania czynnej służby wojskowej. W literaturze i orzecznictwie przestępstwo to powszechnie jest uważane za występek trwały. Jednak szczegółowa analiza wskazuje, że zabronione zachowanie nie polega na wywoływaniu i podtrzymywaniu stanu sprzecznego z prawem, a na jego jednorazowym wywołaniu. Stan ten, oderwany od zachowania sprawcy, istnieje następnie niezależnie od tego, że sprawca nadal nie stawia się do służby wojskowej. Z punktu widzenia prawa administracyjnego obowiązek stawienia się do służby wojskowej istnieje nadal, mimo upływu terminu, jednak czyn zabroniony polega na niestawieniu się do służby wojskowej we wskazanym terminie, co powoduje, że mamy tu do czynienia nie z przestępstwem trwałym, a z jednorazowym występkiem z zaniechania. Ma to istotne znaczenie dla określenia czasu popełnienia czynu i ustalenia początku biegu terminu przedawnienia karalności.

Published: September 2023

Przedmiotem artykułu są rozważania nad art. 96 § 3 Kodeksu wykroczeń, sankcjonującym odmowę wskazania, na żądanie uprawnionego organu, komu właściciel lub posiadacz pojazdu powierzył pojazd do kierowania lub używania w oznaczonym czasie (art. 78 ust. 4 ustawy Prawo o ruchu drogowym). Celem artykułu jest prezentacja kręgu podmiotów zobowiązanych na podstawie tych przepisów oraz podmiotów uprawnionych do żądania informacji o tym, komu właściciel lub posiadacz pojazdu powierzył pojazd do kierowania lub używania w oznaczonym czasie. Ponadto zwrócono uwagę na okoliczności, które – mimo iż stanowiły przypadki niezastosowania się do normy wynikającej z art. 78 ust. 4 cyt. ustawy – nie mogły skutkować odpowiedzialnością za przedmiotowe wykroczenie. Artykuł zawiera także analizę orzecznictwa odnośnie prawa do obrony w kontekście odpowiedzialności za wykroczenie z art. 96 § 3 Kodeksu wykroczeń. Autor wskazuje, że przepis Kodeksu wykroczeń nie ogranicza prawo do obrony.
THE PLACE OF OSINT IN THE CYBER KILL CHAIN
Authors:   State University of Telecommunications, Zaporozhchenko M. M.
Published: September 2023

In recent years, there has been a trend towards an increase in the number of cyber attacks on organizations and individual users. In many cases, a key factor in the implementation of an information security incident is the attacker's effective preparation for a cyber attack: target selection, reconnaissance, i.e. obtaining any information that may be needed when planning an attack, weaponization based on discovered defense mechanisms, software and hardware, etc. and delivery, i.e. choosing how the malware will reach the victim and what steps will be required to activate it further. Having a significant amount of important and critical information for the organization from the point of view of ensuring security provides the attacker with the opportunity to choose the optimal attack scenario and significantly increases the chances of its success. The problem is that today's OSINT methods and tools allow you to find almost any information that is not protected in a real way, which significantly increases the risks, especially for organizations that find it difficult to control all the information that their employees post on social networks, disclose in interviews or accidentally enters the Internet. However, most intelligence tools are not only available to attackers, so ethical hackers and penetration testers can also use OSINT tools to examine an organization's vulnerabilities and improve its defenses before attackers exploit those vulnerabilities. The article examines the main methods of intelligence based on open sources, considers the most common and most often used OSINT tools, describes the life cycle of a cyber attack and defines the stages that require the use of OSINT tools when conducting an audit of the organization's information security and penetration tests.

Algorithm for dynamic channel reservation of aggregated data flow
Authors:   State University of Telecommunications, Grynkevych G. O.
Published: September 2023

In modern telecommunications systems, dynamic reservation of channel resources for an aggregated data stream is one of the most important tasks, as it allows for efficient use of available resources and provides high-quality service to subscribers. Developing an algorithm for dynamic reservation is a challenging task, as it requires ensuring optimal resource allocation among subscribers during variable network load. This article discusses an approach to developing an algorithm for dynamic reservation of channel resources for an aggregated data stream that provides efficient resource allocation and ensures high-quality service to subscribers. Specifically, approaches to dynamic resource allocation based on network load and approximation and optimization methods that reduce algorithm complexity and ensure its effective operation will be considered. The results of this work can be useful for telecommunications system developers and for research in the field of telecommunications. The article proposes an algorithm for dynamic reservation of channel resources for an aggregated data stream. The implementation of this algorithm is performed on a VPN gateway designed to manage data streams, filter them, and organize priority access to data streams in the VPN tunnel. In the event of a network load, the developed algorithm should first evaluate the network status and, based on the results obtained, perform data stream access control functions, taking into account their priorities. Based on the developed algorithm for dynamic reservation of channel resources for an aggregated real-time data stream, this section establishes a system of criteria for efficient utilization of channel resources for protected corporate multiservice communication networks under conditions of network resource availability for servicing the proposed workload from the access network and network congestion. The approach to prioritizing data streams takes into account user categories and service classes, which, unlike existing tools, allows for the task of prioritized servicing under load conditions and determines the best use of the available channel resources at the transport layer of protected corporate multiservice communication networks.
Spectral efficiency of signals of multichannel communication systems with orthogonal modulation
Authors:   State University of Telecommunications, Klobukova L. P.
Published: September 2023

The errors of restoration of original continuous signals in digital communication systems with orthogonal modulation of equidistant subcarriers (the so-called OFDM technology) are considered. The theory of radio circuits and signals is applied as a scientific and technical basis of the problem. The spectra of discrete signals were analysed, the influence of violations of the conditions of Kotelnikov’s theorem and the asymptotics of the recovery errors of the original continuous signals were investigated. Methods for analysing composite signals with arbitrary selection of the sampling frequency of spaced subcarriers have been developed, and quantitative estimates of the quality of signal restoration on the receiving side have been obtained using the method of summing Fourier integrals according to Feuer. It is shown that when the amount of frequency shift of the basic series decomposition functions and the width of the spectrum of the main and side lobes in the spectrum of the output signal are matched, it is possible to count on the minimal influence of mutual interference and intersymbol interference of the composite signal. In addition, it was established that the correct selection of the Feuer kernel and discretisation of OFDM signals allows increasing the accuracy of signal recovery on the receiving side and the overall efficiency of the wireless communication system due to the reduction of Gibbs pulsations energy. Spectral efficiency of signals, which are used in wireless communication systems, depends in great degree from correct choice of smoothing kernel. Also, with a dynamic change in the number of members of the decomposition series in wireless networks, the influence of frequency collisions, Gibbs ripples, and the level of intersystem interference is reduced. Comparative analysis of other smoothing factors, such as Lanzosh factor, two-parameter factor, etc. when decomposing in a series on a quasi-orthogonal system of basis functions shows that the errors of restoring the output signals depend on various influencing factors. It was also established that there couldn’t be a universal recipe for choosing a smoothing multiplier (or kernel). This problem requires additional research of an analytical and computational nature.
