Unrestricted kinematic alignment corrects fixed flexion contracture in robotically aligned total knees without raising the joint line in extension
Authors: Sappey‐Marinier Elliot , Bini Stefano
Published: November 2023

Purpose

Mechanically Aligned Total Knee Arthroplasty (MA TKA) typically addresses fixed flexion contractures (FFC) by raising the joint line during extension. However, in unrestricted Kinematically Aligned TKA (KA TKA) utilizing a caliper‐based resection technique, the joint line is not raised. This study aims to determine the efficacy of KA TKA in restoring full extension in patients with FFC without increasing distal femoral resection, considering tibial bone resection and sagittal component positioning.

Methods

A retrospective study was conducted by a single surgeon, involving patients who underwent primary robotically assisted cruciate retaining unrestricted KA TKA between June 1, 2021, and December 1, 2022. Complete intraoperative resection and alignment data were recorded, including the thickness of distal femoral and proximal tibial bone cuts. Patients with a preoperative FFC ≥ 5° (study group) were compared to those with FFC < 5° (control group). The impact of variations in tibial resection and sagittal component positioning was assessed by comparing the heights of medial and lateral resections, sagittal femoral component flexion, and tibial slope. Group comparisons were analyzed using the Wilcoxon Signed Rank Test, with a significance level set at p < 0.05.

Results

A total of 48 KA TKA procedures met the inclusion criteria, with 24 performed on women. The mean preoperative FFC in the study group was 11.2° (range: 5–25°), while the control group exhibited 1° (range: 0–4°) (p < 0.001). There were no statistically significant differences observed between the study and control groups in terms of distal femoral resections, both medially (p = 0.14) and laterally (p = 0.23), as well as tibial resection heights, both medially (p = 0.66) and laterally (p = 0.74). The alignment of the femoral component flexion and tibial slope was comparable between the two groups (p = 0.31 and p = 0.54, respectively). All patients achieved within 5 degrees of full extension at closure.

Conclusion

Robotic arm‐assisted unrestricted KA TKA effectively restores full extension without raising the joint line during extension for patients with a preoperative fixed flexion contracture.

Published: November 2023

Neural progenitor cells (NPCs) are essential for in vitro drug screening and cell-based therapies for brain-related disorders, necessitating well-defined and reproducible culture systems. Current strategies employing protein growth factors pose challenges in terms of both reproducibility and cost. In this study, we developed a novel DNA-based modulator to regulate FGFR signaling in NPCs, thereby facilitating the long-term maintenance of stemness and promoting neurogenesis. This DNA-based FGFR-agonist effectively stimulated FGFR1 phosphorylation and activated the downstream ERK signaling pathway in human embryonic stem cell (HESC)-derived NPCs. We replaced the basic fibroblast growth factor (bFGF) in the culture medium with our DNA-based FGFR-agonist to artificially modulate FGFR signaling in NPCs. Utilizing a combination of cell experiments and bioinformatics analyses, we showed that our FGFR-agonist could enhance NPC proliferation, direct migration, and promote neurosphere formation, thus mimicking the functions of bFGF. Notably, transcriptomic analysis indicated that the FGFR-agonist could specifically influence the transcriptional program associated with stemness while maintaining the neuronal differentiation program, closely resembling the effects of bFGF. Furthermore, our culture conditions allowed for the successful propagation of NPCs through over 50 passages while retaining their ability to efficiently differentiate into neurons. Collectively, our approach offers a highly effective method for expanding NPCs, thereby providing new avenues for disease-in-dish research and drug screening aimed at combating neural degeneration.

Authors: Bertrand Émilie , Caru Maxime , Harvey Audrey , Dodin Philippe , Jacquemet Vincent , Curnier Daniel
Published: November 2023

Purpose

The aim was to provide evidence about the prevalence, incidence, and risk factors of cardiac electrical abnormalities in childhood acute lymphoblastic leukemia (ALL) survivors.

Methods

We included all original studies reporting the incidence and/or prevalence of cardiac electrical abnormalities and/or risk factors associated with cardiac electrical abnormalities in childhood ALL survivors (< 21 years old at the time of their initial cancer diagnosis) who were post-treatment. Searches of the databases PubMed, Ovid MEDLINE(R) and Epub Ahead of Print, In-Process, In-Data-Review & Other Non-Indexed Citations, Daily and Versions(R), Ovid All EBM Reviews, Ovid Embase, and ISI Web of Science were completed in May 2023. The risk of bias was assessed using the standard JBI critical appraisal checklists.

Results

The 11 studies included in this review (N = 1,264 participants) evaluated various parameters, including different cardiac electrical abnormalities. Five studies reported heart rate abnormalities (0–68%), six reported repolarization disorders (0–30%), two reported depolarization disorders (0–1%), seven reported rhythm disturbances or abnormalities (0–100%), four reported conduction disorders (0–10%), and three reported unclassified abnormalities (1–38%). No risk factors were reported.

Conclusions

Electrical heart problems have been observed in childhood ALL survivors after completion of treatment. Large prospective studies in childhood ALL survivors, clear definitions of cardiac electrical abnormalities, and comparison with a control group are warranted.

Implications for cancer survivors

Cardiac electrical abnormalities induced by chemotherapy-related cardiotoxicity in the growing population of childhood ALL survivors need to be better characterized to ensure better long-term follow-up and improve overall survival rate.

Reflections on Identity Exploration in the Time of the COVID-19 Pandemic from Queer Students of Color
Authors: Duran Antonio
Published: November 2023

Abstract: The context of the COVID-19 global pandemic has shaped all aspects of modern life, creating a unique circumstance for minoritized groups as they have explored important questions related to the self. Specifically, scholars, practitioners, and policymakers have expressed interest in understanding how the COVID-19 pandemic affected minoritized groups, including queer people and queer people of color, specifically. This study used data from a longitudinal constructivist grounded theory project following queer students of color within and beyond their time in college to examine how the COVID-19 pandemic influenced the process of identity exploration for these individuals. Findings revealed that queer students of color engaged in self-reflection about identities because of the isolation, reexamined navigating relationships at home and within educational institutions, and sought connections and guidance through online spaces. Informed by the study findings, the manuscript provides implications for future research and practice in higher education and student affairs.
(Re)orienting White Spaces Through Compañerismo : Latino Graduate Students Creating Homeplaces at a PWI
Authors: Patrón Oscar E. , Flores Osly J. , Medina Øscar
Published: November 2023

Abstract: This study employed homeplace and compañerismo as conceptual frameworks to examine the role of space among Latino men in graduate school. While research has highlighted the importance of space for marginalized students on college campuses, this literature has primarily focused on the undergraduate level. Such is valuable work, yet it is critical to examine spatial dynamics among graduate students. Here, we highlight spaces important to this group of students while centralizing close-knit relationships as an added layer. Analysis of the data revealed the continuous importance of the participants’ compañerismo across university spaces, making both compañerismo and space central components across themes, which included reciprocity of space and compañerismo, bending space through compañerismo, and compañerismo as empowerment. We conclude with implications for practice and research.
What to Think about When Thinking about Digitization of Manuscripts
Authors: Hanneken Todd R.
Published: November 2023

Abstract: This article contributes to the discussion of the impact digitization has had on cultural heritage conservation and scholarship by illustrating the range of modes within the general category of digitization. Before selecting a mode, users should reflect on the questions that conservators and scholars ask when examining an artifact. Various modes of digitization may be appropriate for addressing those questions, especially when a manuscript is studied as more than a text container. The advantages and disadvantages compared to firsthand experience are different for each mode. The article addresses, in particular, those modes that attend to range and resolution of reflected, fluoresced, and transmitted color (multispectral imaging) and texture (reflectance transformation imaging [RTI]). It concludes by considering current tools for integrating spectral imaging and RTI.
The First Lutheran Hymnals of 1524
Authors: Leaver Robin A.
Published: November 2023

Abstract: The year 2024 marks the five hundredth anniversary of the birth of the Lutheran hymnal. During the winter of 1523/24 Luther and his colleagues in Wittenberg began expressing their theology in poetry and music. Like contemporary news ballads the early Lutheran hymns were first circulated from Wittenberg on single printed sheets, which were reprinted by printers in other towns and cities. One of them, Jobst Gutknecht of Nuremberg, reprinted a collection of eight of the early Wittenberg hymns, thus creating the first Lutheran hymnal, the Achtliederbuch (Eight Song Book). Later the same year, 1524, two different hymnals with similar contents were published in Erfurt. Like Gutknecht’s Achtliederbuch the twenty-five hymns they contain were reprinted from single sheet Wittenberg broadsides. Towards the end of 1524 a set of part-books were published in Wittenberg with Walter’s polyphonic settings of hymns mostly by Luther, who also provided a preface. Luther’s close connection to the project has accorded the collection a kind of foundational status as the primary Wittenberg hymnal of 1524. However, there is evidence–explored in this article–that there must have a been a basic Wittenberg collection of thirty-two primary hymns that pre-date both Walter’s part-books for choirs, and the 1524 hymnal specifically issued for the Wittenberg congregations.
The Ethical Message in Huang-Lao Manuscripts: Applying the Laozi ’an Living Riddle as a “Model of Modeling”
Authors: Small Sharon Y. , Patt-Shamir Galia
Published: November 2023

The objective in this article is to apply a Daoist model of an ethic derived from the Laozi on writings of the Huang Lao tradition to offer a unique Daoist cosmically derived ethic in its own terms . Having our point of departure in the Laozi we refer to its paradoxical language as a living riddle that is inherent to the tradition, and as such it suggests a “model of modeling.” We find this model in Laozi 25, according to which self-so ( ziran 自然) serves as foundation for an ethic that is neither dichotomizing nor rests on human moral conventions, rather as a guiding philosophy of living. On this basis we explore the question of an ethic in the Huang Lao tradition.
Comparative evaluation of estrus synchronization protocols on reproductive performance and estrus behavior in Barbados Black Belly sheep
Authors: Mohan Krishna , Kumar Nitu
Published: November 2023

Background and Aim: Estrus synchronization of ewes has been accomplished using several protocols with various degrees of success in improving reproductive efficiency and obtaining the most effective protocol used in sheep farming. This study aimed to compare the effectiveness of three treatment protocols and to record the intensity and duration of estrus signs and pregnancy rate in Barbados Black Belly (BBB) sheep.

Materials and Methods: Thirty-two primipara BBB ewes aged 18–24 months were equally divided into three treatment groups. T1: the ewes were injected intramuscularly with 2 mL Lutalyse (PGF2α) (10 mg) on days 0 and 10. T2: 1 mL Fertiline (50 μg; Gonadorelin acetate) on day 0 and 2 mL lutalyse (10 mg) on day 7. T3: 1 mL fertiline (50 μg) on day 0, 2 mL lutalyse (10 mg) on day 7, and 1 mL Fertiline (50 μg) on day 9. Estrus response was assessed using naturally mating rams and ewes. Pregnancy was determined using ultrasonography between 55 and 80 days after the last hormonal injection. The following estrus signs were noted: Swollen vulva, mucus discharge, sniffing, excitement, loss of appetite, mounting, and rapid tail movement.

Results: Of the expressed signs, swollen vulva was most frequent, whereas loss of appetite and mucus discharge were the least overt signs recorded. The estrus response (%), onset (%), and duration (h) in ewe synchronization of the three treatment protocols were 100%, 58.3 ± 23.4%, and 48.0 ± 18.2 h (T1), 100%, 61.7 ± 41.2%, and 45.0 ± 27.0 h (T2), and 37.5%, 32.1 ± 1.7%, and 29.2 ± 1.25 h (T3), respectively. The pregnancy rates were 87.5%, 87.5%, 37.5%, and 50.0% in T1, T2, T3, and T4, respectively.

Conclusion: Prostaglandin F2α+PGF2α and GnRH+PGF2α synchronization protocols were more effective in the fertilization of BBB ewes with better expression of estrus signs compared with the GnRH+PGF2α+GnRH (OVS) protocol.

Keywords: Barbados Black Belly, estrus behavior, estrus synchronization, ewes, Trinidad.
Spatio-temporal dynamics of land use and land cover in the Alibori basin in Northern Benin Republic (West Africa)
Authors: Alamou Abraham Babatounde , Arouna Ousséni , Oloukoi Joseph
Published: November 2023

Forest ecosystems of the Alibori basin are subject to multiple anthropogenic pressures witch therefore modify their land use and their land cover. This research aims at analyzing the spatio-temporal dynamics of land use and land cover in the Alibori basin in Northern Benin. The methodological approach used is based on the diachronic analysis of land cover from Landsat 2, 7, and 8 satellite images acquired respectively in 1980, 2000, and 2020, and the evaluation of land cover change parameters (conversion rate, level of deforestation, intensity and speed of change of land cover units). The results obtained reveal that the number of classes has increased from 8 to 9 with the appearance of plantations between 1980 and 2000. Between 1980 and 2020 the basin recorded a degradation of forest formations and an anthrogenization of savannah formations. The intensity and speed of loss of area are quite rapid in dense dry forests, open forests, and wooded savannahs between 1980 and 2020. The average rate of deforestation decreased from 1.27% annually between 1980 and 2000 to 1.26% annually between 2000 and 2020.
A study of the anticancer potential of Pluronic F-127 encapsulated Fe2O3 nanoparticles derived from Berberis vulgaris extract
Authors: Alzahrani Abdullah R.
Published: November 2023

The study synthesized Pluronic F-127 nanoparticles that encapsulate Fe2O3 (PF127Fe2O3NPs), nanoparticles, characterized their formation, and evaluated their cytotoxicity and anticancer activity using Berberis vulgaris leaf extract, using various analytical methods such as FTIR, Ultraviolet-visible, photoluminescence, dynamic light scattering, X-ray diffraction, and morphology analysis. We assessed the antioxidant properties of PF127Fe2O3NPs, cytotoxicity, and apoptosis through 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay and acridine orange/ethidium bromide staining in breast cancer cells, such as MCF7, and MDA-MB-231. The characterization results demonstrated that PF-127 was coated with Fe2O3 nanoparticles. MTT assay data revealed that PF127Fe2O3NPs effectively prevent cancer cells from proliferating and act as an anticancer drug. The antimicrobial results revealed that the fabricated nanoparticles are effective against gram-negative (Klebsiella pneumoniae, Escherichia coli, and Shigella dysenteriae) and gram-positive (Streptococcus pneumoniae, Staphylococcus aureus, and Bacillus subtilis) bacteria. Treatment of PF127Fe2O3NPs in a dose-dependent manner on MCF7, and MDA-MB-231, exhibited increased antioxidant activity, nuclear damage, and apoptotic activity. These results confirm the apoptotic activity of PF127Fe2O3NPs. The study concludes that MCF7 appears to be more sensitive to PF127Fe2O3NPs than MDA-MB-231. In conclusion, we have found that it can be used as an effective antioxidant and anticancer agent in therapeutics.
A deep neural network model for paternity testing based on 15-loci STR for Iraqi families
Authors: Khalid Donya A. , Nafea Nasser
Published: November 2023

Paternity testing using a deoxyribose nucleic acid (DNA) profile is an essential branch of forensic science, and DNA short tandem repeat (STR) is usually used for this purpose. Nowadays, in third-world countries, conventional kinship analysis techniques used in forensic investigations result in inadequate accuracy measurements, especially when dealing with large human STR datasets; they compare human profiles manually so that the number of samples is limited due to the required human efforts and time consumption. By utilizing automation made possible by AI, forensic investigations are conducted more efficiently, saving both time conception and cost. In this article, we propose a new algorithm for predicting paternity based on the 15-loci STR-DNA datasets using a deep neural network (DNN), where comparisons among many human profiles are held regardless of the limitation of the number of samples. For the purpose of paternity testing, familial data are artificially created based on the real data of individual Iraqi people from Al-Najaf province. Such action helps to overcome the shortage of Iraqi data due to restricted policies and the secrecy of familial datasets. About 53,530 datasets are used in the proposed DNN model for the purpose of training and testing. The Keras library based on Python is used to implement and test the proposed system, as well as the confusion matrix and receiver operating characteristic curve for system evaluation. The system shows excellent accuracy of 99.6% in paternity tests, which is the highest accuracy compared to the existing works. This system shows a good attempt at testing paternity based on a technique of artificial intelligence.
The θ-derivative as unifying framework of a class of derivatives
Authors: AL Nuwairan Muneerah
Published: November 2023

In this article, we develop a unified framework for studying some derivatives defined as limits. This framework, the

θ

\theta

-derivative, is used to investigate the relationships between these derivatives and their relation to the ordinary derivative. It is shown that the existence of any of these derivatives is equivalent to the existence of the ordinary derivative. By using these results, we show that two derivatives that appear in the literature under different names are actually identical, and an infinite family of derivatives actually consists of only one member. We also give a unified form for the integral corresponding to these derivatives, generalize the standard analysis theorems to this setting, and relate our results to those of other researchers. Finally, we address the question of whether these derivatives should be considered fractional derivatives.

Authors: Dähne Lars , Olszyna Mateusz , Dähne Götz , Debrassi Aline
Published: November 2023

Es wird ein neues Instrument für labelfreie Messungen auf der Basis von optischen Low Q-Whispering Gallery Modes vorgestellt, bei der mit miniaturisierten Sensorbeads verschiedene Anwendungsfelder adressiert werden. Als Sensoren dienen fluoreszente sphärische Beads mit Durchmessern von 7–12 Mikrometern, die unabhängig vom Messgerät in kleinsten Räumen eingesetzt werden können und mit Analytmengen im Femtogrammbereich auskommen. Die sphärischen Beads mit einer sehr glatten Oberfläche und hohem Brechungsindex dienen als Resonatoren für zirkulare Lichtwellen. Für die Messung wird der Fluoreszenzfarbstoff in den Sensoren mit einem Laser angeregt. Ein Teil der Fluoreszenz wird an der Partikeloberfläche total ins Partikel zurück reflektiert, so dass sich zirkulierende Wellen bilden, die bis zu 10,000 Mal umlaufen. Ihre Resonanzfrequenz hängt empfindlich vom Partikeldurchmesser und der Brechungsindexdifferenz zwischen Partikel und Medium ab. Bei Adsorbtion von Molekülen verschiebt sich die Resonanzfrequenz, da sich beide Parameter ändern. Für die Messung dieser Verschiebung wurde ein kompaktes Gerät mit Anregungslaser, hochauflösendem Spektrometer, CCD-Zeile, XYZ-Stage, Mikroskop, Kamera, Gerätesteuerung und Auswertesoftware entwickelt. Es werden einige Anwendungsbeispiele in der Biosensorik, der Layer-by-Layer Beschichtung, der Wirkstofffreisetzung und der Lösungsmittelsensorik präsentiert, die das breite Potential und Vorteile gegenüber auf dem Markt befindlicher, alternativer Meßmethoden demonstrieren.

Published: November 2023

Os processos para avaliar o desempenho organizacional têm se tornado mais complexos. No entanto, os estudos têm se debruçado em estágios específicos do desenvolvimento dos Sistemas de Avaliação de Desempenho, desconsiderando sua integralidade. Assim, a pesquisa busca descrever como ocorre o desenvolvimento dos estágios evolutivos de um Sistema de Avaliação de Desempenho (SAD) no contexto portuário público brasileiro. Foi feito um estudo de caso, com acompanhamento de um ano, período no qual o Sistema percorreu os estágios do Ciclo de Vida, proposto por Bourne et al. (2000). Para o desenvolvimento do Sistema, os dados foram coletados por meio de entrevistas semiestruturadas com o decisor de uma holding portuária pública, norteado pela metodologia Multicritério de Apoio à Decisão-Construtivista (MCDA-C). Os resultados dessa pesquisa evidenciam como um SAD é projetado, implementado, usado e atualizado, oferecendo contribuições ao campo de pesquisa, o qual é criticado pela falta de evidência que demonstra o Ciclo de Vida completo de SADs. O estudo também traz evidências sobre a construção de conhecimento gerado durante os estágios do Ciclo de Vida do Sistema. Dessa forma, pôde-se contribuir para isso ao dispor à organização um modelo capaz de mensurar e subsidiar as atividades de gestão e a tomada de decisão. A combinação dos aportes teóricos ao conhecimento advindo dos resultados empíricos ilustrados corrobora a área de pesquisa de Avaliação de Desempenho sobre a validade do Ciclo de Vida do SAD e contribui para alavancar o desempenho da organização.

Published: November 2023

The processes for appraising organizational performance have become more complex. However, studies have focused on specific stages in the development of Performance Appraisal Systems, disregarding their completeness. This research seeks to describe how the evolutionary stages of a Performance Appraisal System (PAS) develop in the Brazilian public port context. A one-year case study was carried out, during which time the System went through the stages of the Life Cycle proposed by Bourne et al. (2000). To develop the System, data was collected through semi-structured interviews with the decision-maker of a public port holding company, guided by the Constructivist Multi Criteria Decision Aid (MCDA-C) methodology. The results of this research show how a PAS is designed, implemented, used and updated, offering contributions to the field of research, which is criticized for the lack of evidence demonstrating the complete Life Cycle of PAS. The study also provides evidence on the construction of knowledge generated during the stages of the System Life Cycle. In this way, it was possible to contribute by providing the organization with a model capable of measuring and supporting management activities and decision-making. The combination of theoretical contributions with the knowledge derived from the illustrated empirical results corroborates the area of Performance Appraisal research on the validity of the PAS Life Cycle and contributes to leveraging the organization's performance.
Perrotta-Marciano Burnout Risk Interview 1 (BORI-1): The new clinical interview to investigate burnout risk in public and private workplaces
Authors: Giulio Perrotta , Antonio Marciano , Gianfranco Fabiano
Published: November 2023

Starting from the general concept of "burnout", thus describing the lack of energy, fatigue, and unproductivity at work that a person develops in the workplace, the present paper defines the specific characteristics of the syndrome and related contexts and then proposes a new psychometric instrument (Perrotta-Marciano Burnout Risk Interview 1, BORI-1), in the interview version, capable of assessing and graduating the risk of the same, to intervene promptly in borderline situations that could degenerate into injurious and self-injurious acts. The interview aims to analyze the risk of burnout in individuals who work in both the private and public sectors and who for reasons of service may be put under pressure, even if they have passed the medical and psychiatric examination. It is therefore proposed as a tool for investigation, prevention, and clinical evaluation of burnout syndrome in its clinical signs, thus bridging the critical issues noted in the current psychometric instruments dedicated to the subject under consideration.

Published: November 2023

Ylang-ylang (Cananga odorata Hook.f. & Thoms.) is cultivated in many tropical areas of the world for the multiple applications of the essential oil extracted from its flowers. The aim of this work was to determine the concentrations of macro-nutrientes and micro-nutrients in the different ylang-ylang organs in two treatments, without fertilization and with commercial fertilization, based on a nutritional analysis of the soil of a production farm located in Chongón, Guayas, Ecuador. The concentrations of N, P and Mg were significantly higher in the treatment with fertilization (16.82; 2.96; 3.81 vs. 14.63; 2.39; 3.12 g/kg, respectively). Concerning micronutrients, in the treatment with fertilization, Mn, Cu and Mo concentrations were significantly higher (73.00; 13.50; 1.28 vs. 44.96; 9.08; 0.50 mg/kg), while Cl concentration was significantly lower (1692.58 vs. 3488.25 mg/kg). Significant differences were also found in nutrient concentration as a function of organs. The C. odorata N, P, K, Ca, Mg and S extraction is 30.83; 3.46; 12.87; 25.50; 4.85 and 3.35 kg/ha, respectively. Higher concentrations of N, Ca and K are suggested for this crop. These results contribute to the improvement of the quality of fertilization in the ylang-ylang cultivation.

Authors: Ilias Faiza  , Gaouar Semir Bechir Suheil
Published: November 2023

The high price of commercial products against pests impose small farmers to use a locally available baits against C.capitata that is the most fruit fly in our country. The aim of this research was to evaluate the effectiveness of food-based attractants for the capture of C. capitata as well as their selectivity on the populations of beneficial arthropods. we tested some local fermentation products compared to commercial lures (CeraTrap®). Four attractants were evaluated in two peach orchads. Field evaluations show that local fermentation products, particularly the red wine solution outperformed other food-based attractants. However, the average of fruit damage was differed between the four attractants and it was high in the border than in the center of each attractants plot. These attractants also were selective, capturing few beneficial arthropods. It will be necessary to focus our research on how to optimally employ such a trap in conjunction or alternative with other control techniques to drive concerted and integrated pest management due to its low environmental impacts and selectivity toward beneficial insects.

Computational Review and Assessment of The Urban Heat Island Effect and Its Impact on Building Space Conditioning
Authors: Banerjee Debanjali
Published: November 2023

This paper reviews and reports the recent progress and knowledge on the specific impact of the urban heat island (UHI) effect on building space conditioning for vulnerable housing where lack of air conditioning and fuel poverty causes indoor overheating, thus increasing vulnerability. Previous studies demonstrated that the increase of the ambient temperature due to UHI and heat waves impacts adversely cooling energy consumption of buildings and raises the peak electricity demand during summer and heat waves. Given the aging and dilapidated housing conditions in low-income communities, mostly of color and minorities, the economic burden of the cooling energy penalty induced by urban overheating is higher. However, literature on overheating is primarily driven by the physical characteristics of the building such as insulation, albedo, and envelope properties, and the Heat Vulnerability Index (HVI) by demographic data such as age, income, education largely remains isolated thus failing to capture the overall understanding of heat vulnerability and the role architects/urban designers can play in mitigation. Through a computational query review of the last fifteen years of publication, we are inquiring, about how UHI impacts building energy consumption in low-income and poor-quality housing and what role city and housing characteristics play in indoor overheating. Our study suggests, that in the US, due to segregated historic planning policies, low-income houses are often located in low tree canopy areas with varying urban typologies, and higher impervious material which substantially increases the air temperature thus determining energy consumption and anthropogenic heat release which contribute to present-day inequitable exposure to intra-urban heat. Both housing characteristics and the location of housing play a crucial role as similar housing will experience different exposure to intra-urban heat if not located in a heat canyon. Through this literature review, it became evident that there is a gap in the research that fails to connect building characteristics and overheating with heat vulnerability. Research involving UHI and heat vulnerability has continued to advance through energy analysis and mitigation studies, but future studies need to redefine the HVI index, especially by incorporating city and housing characteristics, which can help architects/urban designers make informed design decisions.
Soft Knitted Tensile Membrane Tensegrity Helix-Tower
Authors: Melnyk Viginia
Published: November 2023

This paper explores project-based research approach for using knitted textiles as a participating element in a tensegrity structural system. The design of the tensegrity Helix-Tower takes advantage of the emergent elastic properties of knit material and the self-stress, self-stabilizing characteristics of tensegrity structures. The paper outlines the workflow for working with knit materials, including the feedback loop between small studies, digital models, and simulations, and from small to large prototypes. The resulting prototype is a 2.74-meter (9-foot) helix structured tensegrity tower, which is lightweight, deployable, and at a small architectural scale. The assembly process for the final construction is simple and requires no tools.
The research is novel in its exploration of using knit membranes in tensegrity structures, resulting in a structure that is ultimately more flexible and responsive to movement than traditional tensegrity structures. The design also provides more interactivity with human bodies and the environment. The paper examines the benefits of knitted membrane, including their heterogeneity and uneven stretching. Which provides softness, flexibility, and more movement to the structure. However, questions remain regarding the potential for other environmental factors such as wind or water.
Future work includes exploring the potential and problems of knitted compared to other materials used in tensegrity structures and examining the incorporation of the design into real architectural elements.

Published: November 2023

Статья посвящена описанию понятийного, образного и ценностного компонентов концепта «нүүдл/кочевье», занимающего важное место в картине мира калмыков. Этим определяется актуальность предпринятого исследования. Материал исследования: данные из лексикографических источников калмыцкого языка. Методы исследования: лексико-семантический анализ и лингвокультурологический анализ языковых единиц, входящих в лексико-семантическое поле концепта «нүүдл/кочевье». Результаты: анализ показал, что кочевье в калмыцком языковом сознании соотносится с местом кочевья и связано с идеей передвижения и остановки. Номи-нантом концепта является имя существительное нүүдл. Концепт имеет полевую структуру, ядро образуют обозначения нүүдл, бүүр, бууц, бәәрн, зогсал, орм; их дери-ваты и устойчивые словосочетания, содержащие репрезентанты данного концепта, образуют ближнюю периферию; тексты культуры, ассоциативно связанные с кочевьем, формируют его дальнюю периферию. Образный элемент концепта указывает на обжитое, свое пространство, предназначенное для людей одного рода и животных, принадлежащих данному роду. На высокую оценку кочевья как сакрального пространства указывает ритуализация процесса перекочевки и размещения на новом месте: строгое соблюдение установленных порядков, последовательностей действий, правил коммуникации.
ПРОСТРАНСТВЕННЫЙ АСПЕКТ ХАРАКТЕРИСТИКИ ТОПОХРОНА В МИФОЛОГИЧЕСКОЙ КАРТИНЕ МИРА

В статье рассматриваются изменения отношения носителя лингвистической картины мира древнеанглийского языка к такой составляющей категории топохрона, как пространство с переходом от языческого мировоззрения к христианскому. Холистическое, недискретное отношение к пространственно-временной составляющей мироописания, в частности к топосу, делит пространство вертикально и горизонтально, без применения точных мер, так как это неважно для развития сюжета эпического произведения. Это некая лингвокультурная универсалия, так как такое сознание не зависит от географического места рождения эпического произведения. Статья при помощи лингвистических показателей доказывает, что модель тройственного мира сохраняется и в христианскую эпоху. Данный факт закреплен в произведениях, записанных в период раннего христианства и несущих в себе большое количество отсылок к языческой картине мира.

Problem statement. In multi-position radar systems (MPRS) built into a spatially distributed system of radio interference, a total-range or difference-range method of positioning is used to determine the coordinates of an air target. For their implementation, it is necessary that, at the stage of primary processing in the MPRS, the target response be detected in at least two or three bistatic links "transmitter-target-receiver". Under conditions of low power radio links "transmitter-receiver" and the use of small airborne targets with a small effective scattering surface, it is more likely that the target will be detected in only one channel, for which the total range "transmitter - target - receiver" will be minimal. In this case, the determination of the target coordinates using the total-range or difference-range methods of positioning becomes impossible. Purpose. To develop a method for determining the coordinates of the target in the MPRS, built into a spatially distributed system of radio interference, based on the analysis of the response received in a single bi-static link "transmitter - target - receiver". Results. A method for determining the coordinates of the target based on the analysis of the response recorded in the only bistatic link "transmitter - target - receiver" in the MPRS, the receiving position of which is equipped with an antenna array, is proposed. The developed method provides a target positioning accuracy of 30-50 m with a total range of the bistatic link "transmitter - target - receiver" of 15-20 km and a bearing error of no more than 1 °. Practical significance. The use in the developed method of the phase distribution on the elements of the antenna array, obtained after the correlation processing of the phase-coded keyed signal reflected from the target, provides separate observation at the receiving position of the responses received from illumination signals from transmitters with different codes. This makes it possible to implement, on the basis of this method, a cellular MPRL with transmitters at the nodes of the cell and a receiving position in its center.

Problem statement. The functioning of the navigation equipment of consumers of global navigation satellite systems is carried out against the background of the impact of a set of intentional interference. One of the types of intentional interference is simulated interference, which leads to the issuance of false information about the location, speed and current time by the navigation equipment of consumers. However, the issues of assessing the effectiveness of the navigation equipment of consumers of global navigation satellite systems under the influence of simulated interference have not been fully investigated. Purpose. Determination of the characteristics of detection of navigation signals and simulating interference of the search and detection system of navigation equipment of consumers of global navigation satellite systems. Results. The mathematical modeling method has been used to obtain the characteristics of detecting navigation signals and simulating interference for three search cycles from the interference/signal ratio for different values of the probability of false alarms. Practical significance. The results can be used by specialists in the field of satellite radio navigation in the development of software and hardware to protect domestic navigation equipment of consumers of global navigation satellite systems from simulated interference.

Statement of problem. The active use of wireless technologies requires the development of radio equipment that monitors devices and data transmission networks and, in particular, wireless local area networks of the 802.11 standard (Wi-Fi). The need to identify unauthorized access points and subscriber devices of these networks, including their bearing and localization, is an urgent task of radio monitoring services. Correlation-interferometric direction finders based on a two-channel radio receiving equipment cyclically connected to various pairs of elements of a multi-element antenna system are an effective tool for bearing radio signals. For the direction finding of packet radio signals, direction finders accumulate time samples from different antenna pairs over long time intervals; joint processing of these data allows determining the direction of arrival of radio signals. However, in the frequency range of transmission of signals of the IEEE 802.11 standard, many sources carry out parallel transmission of information in the time-sharing mode, therefore, the direct accumulation of samples entails mixing and combining data generated by different sources. This causes gross bearing errors and requires the development of new ways of joint identification and bearing of packet radio signals. The purpose of the work is to propose a method for determining the identification features of access points and subscriber devices of Wi-Fi networks, which allows combining fragments of data samples when bearing radio sources. Results. The presented method of address bearing, focused on signals of the 802.11 standard, allows detecting OFDM signals, identifying access points and subscriber devices of the local network and forming an estimate of the direction to these sources of radio emissions. Practical importance. The use of address bearing of Wi-Fi network devices increases the functionality of existing analyzers. The presented method of address bearing is implemented based on the mobile direction finder ARTICLE-M [1], which is used in search and localization systems of unauthorized sources of radio emissions.

Problem statement. Microstrip loop structures of various configurations are widely used to form topologies of multi-pole microwave devices. In this regard, there is a need to study the frequency properties and topological features of the construction of loop structures that determine the amplitude and phase frequency characteristics, as well as the overall parameters of a microstrip radio engineering device. Objective. Studying of frequency characteristics of T- and U-shaped loop configurations implemented on the basis of high-resistance and low-resistance segments of microstrip transmission lines that allow configuring small-sized topologies of multi-pole devices with acceptable electrical characteristics. Results. A number of basic topologies of loop structures designed to function in given frequency bands have been studied. With the help of electrodynamic modeling and parametric optimization, according to a number of criteria (given wave resistance, phase shift, reflection coefficient), the necessary geometric dimensions of the modified topologies were determined. The dependence of the frequency band on the geometric dimensions of the low-resistance loop of the T-section is revealed. By the level of “minus” 20 dB from the maximum of the reflection coefficient, the values of the frequency band width of two types of T-structures – symmetrical and counter-pin - were determined and compared. It is shown that the U-shaped section is characterized by an increased frequency band due to better matching, however, its geometric dimensions exceed the dimensions of the basic T-structures. Practical significance. Modified microstrip loop structures in some cases are able to effectively replace quarter-wave segments of transmission lines, on the basis of which most microwave devices are formed (directional couplers, power dividers, electric filters, phase shifters, crossovers, etc.). The use of combinations of T- and U-shaped structures leads to a significant reduction in the area of microstrip devices designed to operate in the UHF and Microwave bands.
