DETERMINING THE OPTIMAL SORTING METHOD BY COMPUTATIONAL COMPLEXITY
Authors:   Master's Student of the Department of Higher Mathematics, Perm National Research Polytechnic University, Kozhemyakina E.V.
Published: January 2022

Sorting is a fundamental building block for many tasks and is ubiquitous both in theory and in practice of computing, being one of the most important operations in database systems, where its effectiveness can significantly affect the overall performance of the system. A sorting network is a combinational sorting scheme constructed from comparisonswap units. The depth of such a contour is a measure of its working time. The Shell sorting method and the bubble method act as basic methods in the use of sorting methods. They are based on the "comparison" sorting algorithm, which uses insertion sorting at each iteration to make the list of alternating elements almost sorted so that at the last iteration the list is almost sorted. The time complexity of sorting depends on the alternation method (called the increment sequence. In this paper, by implementing sorting algorithms in the Python programming language, two methods are compared, and on a large array of data, the optimal sorting method for computational complexity is determined by a key time criterion.

Data analysis techniques in this study were data reduction, data presentation and conclusions. Techniques for ensuring the validity of data Credibility, Transferability, Dependability and Comfirmability. Based on the results of data analysis, it was found that the increase in violations of the kawin lari custom was due to the lack of parental supervision and guidance towards children. Children are not well controlled, which results in children engaging in promiscuity. Elopement is one of the consequences of promiscuity. For the implementation of customary sanctions, it was found that the implementation of the traditional kawin lari sanction in Pinang Merah Village has not been implemented properly. Because there are still many violations of the kawin lari custom. Meanwhile, the community's perception of the kawin lari customary sanction is that it is a rule that must be obeyed by the community. sanctions are a hereditary inheritance from their ancient ancestors and are still used today. However, in reality, the customary sanction of kawin lari has not been implemented properly because there is still selective cutting or favoritism between the community. The suggestion in this research is that the community should obey the village customary rules that apply in Pinang Merah Village by paying customary sanctions given by the customary institution as a sign of having done something wrong. Customary institutions in order to provide understanding to the community to follow the customary rules of Pianang Merah Village, in order to reduce violations of customary sanctions.

An approach to the quantitative determination of endogenous substances in biological fluids by a chromatographic method using a mathematical apparatus
Authors: Smirnov V. V. , Krasnykh L. M. , Ramenskaya G. V. , Kazanbekov S. B.
Published: January 2022

Relevance of the study: The quantification of endogenous substances is an important task in experimental and clinical pharmacology. In the case of working with endogenous compounds, certain difficulties arise. The main one is the impossibility of obtaining the same biomatrix without endogenous compounds for use as standard solutions in the construction of calibration curves. Purpose: The aim of our study was to develop a mathematical methodology for calculating the concentration of endogenous compounds in biological objects measured by chromatography, which allows us to obtain a statistically reliable interval estimation of the concentration of endogenous compounds. Materials and methods: To implement the computational part of the proposed algorithm, the Mathcad engineering calculation program version 15.0 from PTC (Parametric Technology Corporation) is used, which operates under the family of Windows operating systems (XP, 7, Vista, 8). Main results: A mathematical methodology has been developed for calculating the concentration of endogenous compounds in biological objects measured by chromatography, which allows one to obtain a statistically reliable interval estimate of the concentration of endogenous compounds. A feature of this technique is the use of an exclusively analyzed bioobject for quantitative determination of endogenous substances, without the use of so-called “pure” bioobjects for calibration curves, as well as expensive deuterated analogs of markers – substrates of CYP450 isoenzymes and their metabolites. This allows you to maintain the original biomatrix effect when removing the chromatogram. A statistical apparatus is also used to eliminate possible gross errors. To confirm the reliability of the developed method of quantitative determination, the convergence of the results obtained by this method using deuterated standards is established. Conclusions: A mathematical methodology has been developed for calculating the concentration of endogenous compounds in biological objects measured by chromatography, which allows one to obtain a statistically reliable interval estimate of the concentration of endogenous compounds. A feature of this technique is the use of only the analyzed bioobject for quantitative determination of endogenous substances, which allows you to maintain the original biomatrix effect when removing the chromatogram.

Published: January 2022

Different researchers have performed seismic hazard assessment studies for Pakistan using faults sources which differ from Building Code of Pakistan (BCP 2007) with diverse standard deviations. The results of seismic hazard studies indicate that BCP requires gross revision considering micro and macro level investigations. The recent earthquakes in Pakistan also damaged bridge structures and some studies have been conducted by different researchers to investigate capacity of existing bridges.
The most of bridge stock in Pakistan has been designed assuming seismic loads as 2%, 4% and 6% of dead loads following West Pakistan Code of Practice for Highway Bridges. The capacity of eight selected real bridges, two from each seismic zone 2A, 2B, 3 & 4 is checked against BCP demands. Static and dynamic analyses were performed and the piers were checked for elastic limits. It is established that piers are on lower side in capacity and the bridges in zone 2A are generally less vulnerable. Whereas the bridges in zone 2B, 3 and 4 are vulnerable from medium to very high level. Hence, an in-depth analytical vulnerability study of bridge stock particularly in high-risk zone needs to be conducted on priority and appropriate seismic retrofitting schemes need to be proposed.

A decrease in the utilization of fossil energies, mainly by replacing them with renewable energy sources (RESs), is regarded as a potential energy source in today’s applications. RESs are broadly utilized for heating purposes and particularly with applications in solar water heater (SWH). Despite the accessibility of SWH technologies and their affordable prices in Iran, there is no comprehensive study to explain the potential of Iranian regions to supply hot water for household applications. This one-year work, hence, attempts the first dynamical simulation of a solar heating system to provide sanitary hot water (SHW) as well as hot water demanded to heat 47 stations in Iran. Weather data were extracted from METEONORM and environmental-technical analyses performed by thermal solar (TSOL) software. Stations were ranked based on CCR and BCC models in data envelopment analysis (DEA) method using GAMS V 24.1. As with results, a total of 223.1 MWh solar heat is generated annually from all stations that prevent the emission of 64.5 t CO2 every year. According to CCR and BCC models, Bandar Abbas, Chabahar, Fasa, Iranshahr, Kermanshah, Khoramabad, Sarab, Shahr-e-kord, Yasuj, Zanjan, and Zahedan are the best in this regard. Also according to the economic analysis, the average price of home solar heating in Iran is 0.160 $/kWh.
Escaping Helium from TOI 560.01, a Young Mini-Neptune
Authors: Zhang Michael , Knutson Heather A. , Wang Lile , Dai Fei , Barragán Oscar
Published: January 2022

We report helium absorption from the escaping atmosphere of TOI 560.01 (HD 73583b), an R = 2.8R
⊕, P = 6.4 day mini-Neptune orbiting a young (∼600 Myr) K dwarf. Using Keck/NIRSPEC, we detect a signal with an average depth of 0.68% ± 0.08% in the line core. The absorption signal repeats during a partial transit obtained a month later, but is marginally stronger and bluer, perhaps reflecting changes in the stellar wind environment. Ingress occurs on time, and egress occurs within 12 minutes of the white light egress, although absorption rises more gradually than it declines. This suggests that the outflow is slightly asymmetric and confined to regions close to the planet. The absorption signal also exhibits a slight 4 km s−1 redshift rather than the expected blueshift; this might be explained if the planet has a modest orbital eccentricity, although the radial velocity data disfavors such an explanation. We use XMM-Newton observations to reconstruct the high-energy stellar spectrum and model the planet’s outflow with 1D and 3D hydrodynamic simulations. We find that our models generally overpredict the measured magnitude of the absorption during transit, the size of the blueshift, or both. Increasing the metallicity to 100× solar suppresses the signal, but the dependence of the predicted signal strength on metallicity is non-monotonic. Decreasing the assumed stellar EUV flux by a factor of three likewise suppresses the signal substantially.
The Solar Wind with Hydrogen Ion Exchange and Large-scale Dynamics (SHIELD) Code: A Self-consistent Kinetic–Magnetohydrodynamic Model of the Outer Heliosphere
Authors: Michael A. T. , Opher M. , Tóth G. , Tenishev V. , Borovikov D.
Published: January 2022

Neutral hydrogen has been shown to greatly impact the plasma flow in the heliosphere and the location of the heliospheric boundaries. We present the results of the Solar Wind with Hydrogen Ion Exchange and Large-scale Dynamics (SHIELD) model, a new, self-consistent, kinetic–MHD model of the outer heliosphere within the Space Weather Modeling Framework. The charge exchange mean free path is on the order of the size of the heliosphere; therefore, the neutral atoms cannot be described as a fluid. The numerical code SHIELD couples the MHD solution for a single plasma fluid to the kinetic solution for neutral hydrogen atoms streaming through the system. The kinetic code is based on the Adaptive Mesh Particle Simulator, a Monte Carlo method for solving the Boltzmann equation. The numerical code SHIELD accurately predicts the increased filtration of interstellar neutrals into the heliosphere. In order to verify the correct implementation within the model, we compare the results of the numerical code SHIELD to those of other, well-established kinetic–MHD models. The numerical code SHIELD matches the neutral hydrogen solution of these studies as well as the shift in all heliospheric boundaries closer to the Sun in comparison with the multi-fluid treatment of neutral hydrogen atoms. Overall the numerical code SHIELD shows excellent agreement with these models and is a significant improvement to the fluid treatment of interstellar hydrogen.

and TESS photometry, CHIRON Hα spectra, Atacama Large Millimeter/submillimeter Array (ALMA) 13CO and C18O line fluxes, and Very Large Array (VLA) 3 cm continuum fluxes taken contemporaneously over one month. The X-ray to optical observations were presented previously. Here we present the ALMA and VLA data and make comparisons to GM Aur’s accretion and X-ray properties. We report no variability in the observed millimeter CO emission. Using disk chemistry models, we show that the magnitude of the changes seen in the FUV luminosity of GM Aur could lead to a variation of up to ∼6% in CO line emission and changes in the X-ray luminosity could lead to larger changes of ∼25%. However, the FUV and X-ray luminosity increases must last at least 100 years in order to induce changes, which seems implausible in the TTS stage; also, these changes would be too small to be detectable by ALMA. We report no variability in the 3 cm emission observed by the VLA, showing that changes of less than a factor of ∼3 in the accretion rates of TTSs do not lead to detectable changes in the mass-loss rate traced by the jet at centimeter wavelengths. We conclude that changes typically seen in the FUV and X-ray luminosities of TTSs do not lead to observable changes in millimeter CO line emission or jet centimeter continuum emission.
No Significant Correlation between Line-emission and Continuum Substructures in the Molecules with ALMA at Planet-forming Scales Program
Authors: Jiang 蒋 Haochang 昊昌 , Zhu 祝 Wei 伟 , Ormel Chris W.
Published: January 2022

Recently, the Molecules with ALMA at Planet-forming Scales (MAPS) ALMA Large Program reported a high number of line-emission substructures coincident with dust rings and gaps in the continuum emission, suggesting a causal link between these axisymmetric line-emission and dust-continuum substructures. To test the robustness of the claimed correlation, we compare the observed spatial overlap fraction in substructures with that from the null hypothesis, in which the overlap is assumed to arise from the random placement of line-emission substructures. Our results reveal that there is no statistically significant evidence for a universal correlation between line-emission and continuum substructures, questioning the frequently made link between continuum rings and pressure bumps. The analysis also clearly identifies outliers. The chemical rings and the dust gaps in MWC 480 appear to be strongly correlated (>4σ), and the gaps in the CO isotopologues tend to moderately (∼3σ) correlate with dust rings.

Bien que le phénomène d’étalement urbain ait été étudié depuis le début du xx e siècle, et que ses conséquences environnementales soient connues, les politiques publiques qui visent à le maîtriser sont notoirement inefficaces. L’imprécision des définitions généralement utilisées, la focalisation du débat public et scientifique sur les grandes métropoles et les pays développés, ou encore les enjeux liés à l’acceptabilité sociale des politiques en sont responsables.

Published: January 2022

The lesser mealworm (LMW, Alphitobius diaperinus (Panzer); Coleoptera: Tenebrionidae) is increasingly used as a novel food and feed source. The feed materials on which this insect species is reared may contain residues of insecticides from agricultural use. The objective of this study was to determine whether selected insecticides, spiked to the substrate, could bioaccumulate in LMW and/or affect growth or survival. Insecticides were selected and spiked at concentrations equal to the legal limit in EU. Tested substances were chlorpyrifos, propoxur, imidacloprid, spinosad, tebufenozide, fipronil, pirimiphos methyl, cypermethrin, and the synergist piperonyl butoxide (PBO). Cypermethrin and PBO were also tested together. Insecticide concentrations in the spiked substrate and larvae were determined by LC-MS/MS. Concentrations in the larvae were largely below the limit of quantification, meaning that bioaccumulation did not occur. Significant reductions in total yield were observed for spinosad (present in the substrate at 1.6 mg/kg) and imidacloprid (0.12 mg/kg). Spinosad is one of few insecticides that is permitted to be used in organic agriculture, which raises questions over the safety of organic produce for insect rearing. More research on the safety of organic produce treated with this insecticide for rearing of LMW is therefore highly recommended. The reported harmful effects of insecticide residues on LMW need to be accounted for by lowering the current legal limits or reconsidering approval for use. More research is advised particularly on sublethal effects of insecticide residues on LMW on adult beetles.

Control design of mobile sensors for coverage problem is addressed in this paper. The mobile sensors have non-linear dynamics and directional sensing properties which mean the sensing performance is also affected by the pointing directions of the sensors. Different from the standard optimal coverage problem where sensors are assumed to be omni-directional ones, orientation angles of the directional sensors should also be controlled, other than the position control, to achieve the coverage purpose. Considering also the non-linear dynamics of the mobile sensors, new control methodology is necessarily developed for the coverage problem with directional sensors. In the approach proposed, an innovative gradient based non-smooth motion controller is designed for the mobile sensors with unicycle dynamics. With the proposed controllers, the states of sensors will always stay in an positive invariant set where the gradient of the performance valuation function is well-defined if they are initialized within this set. Moreover, the sensors' states are proved to converge to some critical point where the gradient is zero. Simulation results are provided to illustrate the performance of the proposed coverage control strategy.

Para ello, se aplican métodos de análisis SIG y se integran reveladoras fuentes, como las coberturas de Copernicus, las edificaciones y la población por cuadrícula de Global Human Settlement y fuentes estadísticas sobre movilidad residencial y diaria. Este enfoque permite no sólo analizar la organización interna del área funcional, sino también cuantificar en clave de sostenibilidad los principales procesos que en ella acontecen: artificialización, dispersión, discontinuidad y un crecimiento demográfico que se manifiesta en más zonas ocupadas con menor densidad. Los resultados permiten poner en valor los estudios geográficos sobre ocupación del suelo y movilidad en las áreas urbanas funcionales, a la vez que posibilitan una reflexión sobre la función de la escala metropolitana en el marco de la Agenda Urbana. Estamos ante el reto de la sostenibilidad urbana y de la preservación de una infraestructura verde que actúe como garantía de calidad de vida frente a una expansión urbana tendencial, fragmentadora y altamente consumidora de suelo. Por último, la utilidad de las fuentes citadas -y su disponibilidad para los distintos países europeos- posibilitaría analizar la cuestión metropolitana con un enfoque similar en otros sistemas españoles y, en su caso, europeos.
Classe inversée et dynamique interactionnelle en cours de langue étrangère à l'université
Authors: Amer-Medjani Ahlem , Maarfia Nabila
Published: January 2022

Le présent article étudie l'effet de la mise en place de la classe inversée sur les interactions verbales chez des étudiants de première année de licence de français en Algérie. Le dispositif inversé consiste à procéder à un remaniement spatio-temporel de l'apprentissage qui combine des phases d'apprentissage en présence et à distance via l'exploitation de capsules vidéo. Dans cette optique, nous comparons les performances d'un groupe témoin disposant d'un cours traditionnel et d'un groupe "expérimental" bénéficiant d'un apprentissage inversé, en prenant en considération les niveaux taxonomiques de Bloom. Les données collectées consistent en des enregistrements audio transcrits d'interactions lors de séances de cours. Notre démarche est essentiellement comparative dans la mesure où nous avons cherché à cerner la plus-value d'un tel dispositif sur la dynamique interactionnelle au sein du groupe concerné. Les résultats obtenus montrent que l'introduction du dispositif inversé dans l'enseignement-apprentissage de la production orale rend les apprenants plus actifs, plus productifs et plus motivés lors de l'activité.
La subtitulación intralingüística en la docencia de lenguas de especialidad
Authors: Barbasán Ortuño Inmaculada , Pérez-Sabater Carmen
Published: January 2022

La innovación de este trabajo tiene como eje la subtitulación intralingüística de vídeos como herramienta docente en un contexto universitario de aprendizaje de lenguas de especialidad. Se trata de un proceso realizado durante 3 cursos académicos que, tras testar y perfilar el diseño inicial, ha permitido configurar una propuesta metodológica pionera que incentive el aprendizaje de español/inglés como lenguas extranjeras (LE) y contribuya al desarrollo de competencias genéricas/transversales. La propuesta está orientada a hacer más atractiva la práctica de la comprensión oral y al afianzamiento del vocabulario de especialidad en un contexto real, así como fomentar el aprendizaje significativo mediante la retroalimentación entre pares. La actividad involucra a los alumnos como autores de la subtitulación de materiales auténticos: vídeos trabajados en parejas utilizando la herramienta SubtitleWorkshop. Las opiniones del alumnado en encuestas reflejan motivación y satisfacción con la actividad. Mediante esta propuesta se fomenta también el "trabajo en equipo y liderazgo", competencia transversal que se debe trabajar en las asignaturas de la Universitat Politècnica de València. La contribución del estudio resalta el potencial educativo de la tecnología en la subtitulación activa implementada en el aula de lenguas para fines específicos por alumnado que lleva muchos años en el aula de LE.
Online Fanfiction for Language Teaching and Learning
Authors: Sauro Shannon
Published: January 2022

Within the digital wilds, online communities, including communities of fans, represent a rich source of inspiration for the development of computer-mediated tasks and activities that can support alternative and creative approaches to language teaching and learning (Sauro, 2014). By its very nature, fanfiction grows out of fans' deep engagement with a television series, book, movie, performer, band, or other source of media. A challenge facing teachers and researchers is incorporating the enthusiasm and innovation inherent within these online spaces into a formal educational context. This presentation introduces recent research on language learning in the digital wilds. This is followed by an overview of research and pedagogical projects that have explored the development and implementation of fanfiction-inspired teaching materials. It then introduces research carried out by the FanTALES project.
Let's Talk About Cultural Identity
Authors: Bledsoe T. Scott , Setterlund Kimberly A.
Published: January 2022

It is not easy to accurately describe one's cultural identity. There are many factors to consider – from diversity narratives constructed over a single lifetime to those that have been accrued by greater populations. One way to engage this discussion is to provide an overview of diversity key terms that are most closely associated with culture. Important historical events should also be emphasized, as they provide context to many of the challenges faced in modern times. Such topics often cause friction among European Americans – many of whom are loath to judge the actions of those who share their skin color. To start this conversation, the chapter introduces the author, Kimberly, and the five interviewees, Lina, Darnell, Alice, Sheila, and Talia, who discuss their understanding of cultural identity as it applies to their lives.
Applying Critical Theories to Social Media Mining and Analysis
Authors: Sharp Sacha
Published: January 2022

To add to the limited higher education research that seeks to explore the riches of social media as a space for data collection, this chapter provides an example for how to use social media mining in combination with critical theories as an exploratory tool. This study is designed to apply critical theories to social media mining techniques in order to examine how membership organizations have engaged in discourse around racial issues and social inequities in higher education. This chapter will examine how associations engage particular social media contexts for the purpose of influencing educational research and praxis and provide future directions for using social media to expose social injustices.
Narrative Theory as a Pedagogical Strategy for Culturally Responsive Teaching at HBCUs
Authors: Pickett Miller Niya
Published: January 2022

Explication of how Walter Fisher's narrative theory may be utilized as a pedagogical approach toward culturally responsive teaching (CRT) communication-centric courses at historically Black colleges and universities (HBCUs) is shared in this reflective chapter. The fundamentals of this pedagogical lens lean heavily upon applied theoretical knowledge, scholarship, and the author's practical experiences in teaching predominantly Black students. It is argued that the everyday communication style and life experiences of Black students be routinely fused into the communication course curricula, assignments, and activities to improve learning student and engagement. While teaching students at HBCUs are highlighted in this chapter, it is argued that all marginal and minority student populations, at any college or university, can benefit from college classrooms where student narratives are woven into the learning.
Together We S.O.A.R.
Authors: Simpson Teresa E. , Simpson Jr. Artha L. , Bryant Jordan J.
Published: January 2022

Ogbu reflects on the experiences of underrepresented populations in higher education by highlighting the process of cultural inversion. This process rejects assimilation opportunities to develop academically and occupationally due to historical social bias. Without the support of faculty, students from underrepresented groups are often left barren without the proper social and academic skills to contribute to society effectively. Many scholars have stressed the importance of underrepresented student leadership. Within this process, underrepresented students are allowed integration into the culture of higher education and can be properly trained for the task of working towards being a part of the global workforce.
Bridging Social Justice-Oriented Theories to Practice in Teacher Education Utilizing Ethical Reasoning in Action and Case-Based Teaching
Authors: Kavanagh Kara Maura
Published: January 2022

Teachers rarely have preparation to analyze and disrupt the social (in)justice ethical dilemmas that arise in their classrooms. Scans of newspaper headlines reveal teachers making unethical decisions. Yet, teacher education programs rarely include opportunities for students to systematical analyze social justice-oriented cases that illuminate the inequities rooted in our sociocultural context of teaching and learning. This chapter overviews the process for social justice-oriented case-based teaching with an ethical reasoning framework to bridge the theory-to-practice gap in social justice teacher preparation.
