Authors: Inahama Yuzuru
Published: October 2024

In this paper we study a large deviation principle of Freidlin–Wentzell type for pinned hypoelliptic diffusion measures associated with a natural sub-Laplacian on a compact sub-Riemannian manifold. To prove this large deviation principle, we use rough path theory and manifold-valued Malliavin calculus.
Description of Generalized Isomonodromic Deformations of Rank-Two Linear Differential Equations Using Apparent Singularities
Authors: Komyo Arata
Published: October 2024

In this paper, we consider the generalized isomonodromic deformations of rank-two irregular connections on the Riemann sphere. We introduce Darboux coordinates on the parameter space of a family of rank-two irregular connections by apparent singularities. Using the Darboux coordinates, we describe the generalized isomonodromic deformations as Hamiltonian systems.
$\mathrm{C}^{\ast}$-Simplicity of Relative Profinite Completions of Generalized Baumslag–Solitar Groups
Authors: Mukohara Miho
Published: October 2024

Suzuki recently gave constructions of non-discrete examples of locally compact

\mathrm{C}^{\ast}

-simple groups and Raum showed

\mathrm{C}^{\ast}

-simplicity of the relative profinite completions of the Baumslag–Solitar groups by using Suzuki’s results. We extend this result to some fundamental groups of graphs of groups called generalized Baumslag–Solitar groups. In this article, we focus on some sufficient condition to show that these locally compact groups are

\mathrm{C}^{\ast}

-simple and that KMS-weights of these reduced group

\mathrm{C}^{\ast}

-algebras are unique. This condition is an analogue of the Powers averaging property of discrete groups and holds for several currently known constructions of non-discrete

\mathrm{C}^{\ast}

-simple groups.

Published: October 2024

In analogy with the theory of nilpotent orbits in finite-dimensional semisimple Lie algebras, it is known that the principal

\mathfrak{sl}_{2}

subalgebras can be constructed in hyperbolic Kac–Moody Lie algebras. We obtained a series of

\mathfrak{sl}_{2}

subalgebras in rank 2 symmetric hyperbolic Kac–Moody Lie algebras by extending the aforementioned construction. We present this result and also discuss

\mathfrak{sl}_{2}

modules obtained by the action of the

\mathfrak{sl}_{2}

subalgebras on the original Lie algebras.

Aircraft Lightning Environment and Related Test Waveforms
Authors:   AE-2 Lightning Committee
Published: October 2024

The environment and test waveforms defined in this SAE Aerospace Recommended Practice (ARP) account for the best lightning data and analysis currently available. The quantified environment and levels herein represent the minimum currently required by certifying authorities, which is consistent with the approach applied in related lightning documents.

Lightning, like other weather phenomenon, is probabilistic in nature. Levels and waveforms vary considerably from one flash to the next. Within this document, standardized voltage and current waveforms have been derived to represent the lightning environment external to an aircraft. These standardized waveforms are used to assess the effects of lightning on aircraft. The standardized external current waveforms have, in turn, been used to derive standardized transient voltage and current test waveforms that can be expected to appear on cable bundles and at equipment interfaces within an aircraft. When deriving these latter internal induced test waveforms, considerations such as testability and important waveform characteristics that can demonstrate lightning design effectiveness have been taken into account.

The parameters of the standardized waveforms, both external and derived internal induced transients, represent severe versions of each of the characteristics of natural lightning flashes and include all parameters of interest with respect to lightning protection for aircraft. These standardized waveforms are thus referred to as idealized standard lightning environment waveforms, idealized standard waveforms, or just idealized waveforms within this document. The waveforms associated with the external environment are termed the idealized standard external lightning environment. The waveforms associated with the internal induced environment are termed the idealized standard induced transient waveforms.

In every case, more severe versions of each of the individual characteristics of the idealized standard external lightning environment waveforms have been recorded in natural lightning flashes. The more severe individual characteristics of the idealized standard external lightning environment waveforms have never been recorded together within a single lightning flash. Therefore, the parameters combined in the idealized standard lightning environment waveforms provided in this document represent a very severe environment.

The waveforms provided in this ARP are considered to be adequate for the demonstration of compliance for the protection of an aircraft and its systems against the lightning environment and should be applied in accordance with the aircraft lightning strike zones (refer to ARP5414) and test methods (refer to ARP5416) and applicable FAA and EASA advisory and interpretive material.
Ambient Temperature Variable and Fixed-Orifice Fueling Protocols for Light-Duty Gaseous Hydrogen Surface Vehicles
Authors:   Fuel Cell Standards Committee
Published: October 2024

SAE J2601-4 establishes process limits for ambient temperature hydrogen fueling of light-duty automotive vehicles, passenger cars, and trucks that use a compressed hydrogen storage system (CHSS) that meets SAE J2579, where ambient temperature hydrogen fueling is defined as a fueling event where the fuel delivery temperature is greater (e.g., warmer) than the precooled requirements of SAE J2601.

Table 1 depicts the scope of SAE J2601-4 and potential work items for future revisions within this or other documents of the SAE J2601 series. SAE J2601 includes protocols that are applicable for two pressure classes (35 MPa and 70 MPa), three fuel delivery temperature categories (-40 °C, -30 °C, and -20 °C) and CHSS sizes from 49.7 to 248.6 L. Future versions of SAE J2601 may incorporate warmer fuel delivery temperatures (-10 °C and ambient) and smaller compressed hydrogen storage systems for motorcycles and other light-duty applications.

Fueling protocols should be developed based on a set of key assumptions described in Section 7 and Appendix A of J2601. These assumptions should be carefully considered in the development and implementation of an onboard CHSS. In particular, hydrogen storage systems with properties that do not fall within the parameters in Table A3 of SAE J2601 should be further evaluated with protocols developed based on the process limits described in this Technical Information Report (TIR).

For fueling with communications, this TIR is to be used in conjunction with SAE J2799.

This document focuses on the fueling protocol and the equipment necessary to implement the fueling protocol properly. Other requirements may be necessary to operate the station in a proper manner.
Unwanted Neighbours, Unwanted Memory. Slovak–Roma Relations in Marek Vadas’s Six Strangers
Authors: Majerek Rafał
Published: October 2024

In contemporary Slovakia, the Roma population are often seen as unwanted neighbours – a marginalised community, which experiences discrimination in various spheres of life. Anti-Romani sentiment, which constitutes the basis of negative attitudes to- ward the Roma minority, is hardly a new phenomenon; its manifestations, including specific acts of violence, can be found in the past. One of the examples of this kind of violence – the bloody pogrom in Pobedim carried out against the Romani populace by their Slovak neighbours in 1928 – offer a starting point for Marek Vadas’s Six Strangers (Šesť cudzincov, 2021). The historic site of the massacre, which is not commemorated in any form, has be- come a non-site of memory, while the tragic events have been pushed out of Slovak historical consciousness. Vadas’s prose is an attempt to bring them back to the collective conscious- ness and raise a number of important questions concerning the operation of cultural codes that permit and justify violence, the position and responsibility of the bystanders, as well as silence as a form of complicity in acts of aggression. In addition, it introduces a contemporary perspective, pointing to the persistence of mechanisms of discrimination, stigmatisation and exclusion of the Others, understood in many different ways, from the community.
Poetry and Engagement: Monika Herceg in the Labyrinth of Herstory and Itstory
Authors: Wojtaszek Aleksandra
Published: October 2024

Herceg is an award-winning Croatian poet of the young generation. She has published three volumes of poetry: Početne koordinate (2018), Lovostaj. (2019) and Vrijeme prije jezika (2020). Herceg’s poetry abounds in multi-layered, open metaphors, and makes numerous references to vital contemporary problems, primarily connected with systemic violence against women and nature. Particularly the second volume, which is less personal than the poet’s debut, yet more programmatic and engaged, refers to the issues raised by feminist theory. Its compositional axis determines the theme of femininity and women’s stories (herstory). Herceg’s poetry’s engagement not only concerns the choice of specific topics, but is also visible in the gesture of the lyrical subject taking over the perspective of the characters, including non- human actors (itstory). Another major thematic field of the poems is nature, which functions both as a capacious metaphor and in its actual shape. Above all, nature’s and women’s worlds are related by the experience of patriarchal oppression.

Authors:   Korea Institute of Design Research Society, Cho Eun Mi , Um Ki Jun
Published: October 2024

The “Study on the Meaning of Picture Book Sequence Through Visual Component Analysis” is a book that won the La Value Award at the Bologna Children's Book Fair, and it analyzes a total of 906 books in the 1966-2020s by year to examine the visual components of how a picture book leads the reader from beginning to end in a certain space and analyze the meaning. In particular, we classified 30 Korean picture books that have won awards since the 2000s by genre and analyzed in-depth whether the visual components are developing the previous page and the next page in a sequence structure. As a result, it was found that the image expression method was delivered in the most stable visual language, with figurative painting and color being black and difficult, and typography being Serif (light form). It was confirmed that the meaning of the artist's communication toward the reader, such as dreams, hopes, challenges, and courage, to me, family, friends, and the world, does not change even if generations change rapidly. Although a lot of information is pouring out in the digital age, through this study, it is expected that for effective delivery, we will be able to find materials that can move people and sequence me, the world, generations, and generations in visual language.

Published: October 2024

This study focuses on a product design case for an active sound wave sensor-based road condition detection system, with the objective of presenting an effective approach for utilizing patent data to solve product-related issues. To achieve this, prior patents in the same field that implement similar target functions were investigated, and the types of derived patent data were classified to extract ideas that could be applied to product problem-solving. Additionally, based on the derived ideas, prior patents from different fields were analyzed to secure original gap technologies, and specific details were proposed for developing ideas that fulfill the target functions while distinguishing them from existing technologies. Subsequently, the product structure capable of implementing the proposed ideas was reviewed, and the final design was proposed through 3D modeling and rendering. The final design was then reviewed for potential patent infringement and the possibility of securing new patents. This study offers product designers methods for utilizing patent data and proposes a new product design for a road condition detection system using active acoustic sensors, contributing to the implementation of smart cities.

Authors: Apriyanti Rehulina , Hayuningsih Sri , Fitriati Firdaus Mu'minatus
Published: October 2024

The aging process is characterized by a decline in living abilities that can affect the physical and mental well-being of the elderly. The various problems experienced by the elderly require facilities that provide comfort and interior design that supports their physical and mental health. This study aims to analyze the relationship between physical health, psychological health, and space comfort in improving the quality of life of the elderly at the Elderly School of Happy Culture House (SLRBB) in Depok City. The research method used is a qualitative method with data collection techniques through interviews and observations. Data was also obtained through a review of literature relevant to the research topic. Analysis was conducted using triangulation techniques, where data from various sources were compared and put together to obtain more comprehensive results. The results showed that there is a mutually influential relationship between physical health, psychological health, and spatial comfort in the elderly. Good physical health allows the elderly to carry out activities independently, while positive psychological health supports mental well-being. Spatial comfort, including elderly-friendly interior design, increases safety and comfort, and creates a more supportive environment that improves the overall quality of life of the elderly. The implications of this study show the importance of creating a holistic environment for older adults, which not only focuses on physical health, but also psychological well-being and spatial comfort. This can be applied to various programs or facilities that aim to improve the quality of life of the elderly.

This study was carried out on the Yuvarlak Çekirdeksiz grape variety cultivated in Siirt University Implementation and Research Vineyard. Four different doses of liquid seaweed extract was applied at three different periods (control -0 ppm; 1st application period (before flowering) - 1000 ppm; 2nd application period (before flowering + after flowering)-1000 ppm + 1000 ppm = 2000 ppm; and 3rd application (before flowering + after flowering + veraison) -1000ppm + 1000 ppm + 1000 ppm = 3000 ppm). The effects of seaweed application on phenological stages and Total Effective temperature (TET) of Yuvarlak Çekirdeksiz grape variety were compared. When the plants with seaweed applications at different phenological periods were compared with the control, it was observed that plants with the first application period had a full flowering phase three days earlier and the veraison phase six days earlier. The Total Effective Temperature value between full bloom and veraison was determined to be between 659.78-819.98 day-degrees (dd), and it was determined that applying seaweed before flowering shortened the vegetation period compared to the control. In contrast, the other two applications extended the vegetation period.

This study conducts a systematic literature review and meta-analysis on physical literacy, with a focus on gender comparisons among school-aged children and adolescents. Physical literacy (PL) is a multidimensional concept involving social and environmental interaction, knowledge and understanding, motivation and confidence, as well as physical competence. The aim of this study is to evaluate the impact of interventions on these domains and to examine the existing gender gap. The methods employed include a Systematic Literature Review (SLR) and meta-analysis, with data sourced from the Scopus and PubMed databases. The analysis was performed using fixed and random effects models, with publication bias evaluated through Funnel plot, Rank Correlation Test, and Egger's Test. The results indicate that PL interventions have significant effects on several domains with gender-based differences. The social and environmental interaction domain showed no overall significant effect, whereas the knowledge and understanding, and motivation and confidence domains exhibited small but significant effects, with females tending to demonstrate better outcomes. The physical competence domain showed a moderate and significant influence, with males showing greater improvement. The overall physical literacy domain exhibited a significant positive effect, emphasizing the importance of a holistic approach in PL interventions. These findings provide evidence-based recommendations for more inclusive physical education practices and school policies, and help address the gender gap in the development of physical literacy.

The prevalence of breast cancer has been progressively rising as a result of advancements in anti-cancer therapies, however, these patients also experience a variety of long-term adverse effects from their illness and treatments. The current study sought to determine how an exercise training intervention influenced physical and mental health indices in breast cancer patients. A total of 30 female breast cancer patients (aged 42.81 ± 3.31 years, body mass index (BMI) 26.87 ± 0.59 kg/m2, and waist circumference 97.61 ± 1.94 cm) engaged in 12 weekly exercise regimens twice weekly that comprised aerobic, resistance, and flexibility activities. The exercise intervention improved participants' cardiorespiratory fitness, BMI, waist circumference, and muscle function, including sitting to standing, sit-ups, and push-ups. It also showed positive results for post-traumatic stress disorder (PTSD) symptoms, self-reported fatigue, quality of life, and physical, cognitive, and emotional functioning (p < 0.001). In conclusion, our results imply that the advantages of an exercise training program may help breast cancer patients lessen the negative impacts of treatment-related factors on physical performance, overall quality of life, and mental health.

Assessment of the anthropogenic transformation of post-forest vegetation in the village of Guzeripl and its environs (the Republic of Adygea, the Western Caucasus) based on the composition and structure of complexes of dominant species
Authors: Akatov V. V. , Akatova T. V. , Eskina T. G.
Published: October 2024

Definition of the ceno-flora or regional flora in the cenosis, the proportion of species resistant or non-resistant to impacts has become widespread among the methods of indicating disturbances in vegetation cover.

However, such studies, if they are conducted on a large spatial scale, require significant time and do not imply spatial detailing of the results. It is suggested that for several reasons it would be useful to use dominant species to solve this problem. The goal of the research is to demonstrate the possibilities of one of the variants of this approach using the example of vegetation of a small settlement (the mountain village of Guzeripl). It consists in studying the composition (level of synanthropization) and structure of species complexes that dominate communities in relatively large visually homogeneous areas of the terrain (0.15–0.2 ha). The results have shown that, on average, the highest level of synanthropization (transformation) is characteristic of dominant complexes of young fallow lands, a lower level of wastelands and roadsides, and a significantly lower level of old fallow lands and hayfields. In general, communities with a moderate degree of disturbance predominate in the study area. The results also indicate that the impact of anthropogenic factors on areas of vegetation leads to changes not only in the composition of dominant complexes, but also in their structure, the parameters of which can be considered as an additional tool for indicating anthropogenic disturbances.

A huge number of people all over the world suffer from lactose intolerance. The second problem is an allergy to cow milk protein. People with lactose intolerance, as well as those who suffer from cow milk allergies, are forced to significantly limit their choice of ice cream or give it up completely. The article describes a solution to the problem of eating ice cream by children and adults suffering from lactose intolerance and an allergy to cow milk protein, and presents ways to overcome it.

The goal of the research. Objectives for the use of raw materials and component composition for the production of low-lactose ice cream from goat milk. During the research, the quality indicators of the selected raw materials have been studied, the characteristics of the main ingredients for the production of low-lactose ice cream have been substantiated and given. Goat milk, in terms of its quality indicators, is most suitable for the production of ice cream, because it contains more protein, fat, solids, less lactose and does not cause allergies, and therefore it has been chosen as the main raw material for the production of ice cream. A theoretical and practical analysis of the chemical composition and properties of goat milk has been carried out, and compared with cow. To reduce the lactose content, a dual method of lactose hydrolysis has been chosen - the use of probiotic starter cultures and the lactase enzyme. In the process of combined hydrolysis at a temperature of 37-39⁰ C for 4-6 hours, a reduction in lactose content of less than 0.9% is achieved, while the concentration of cells of probiotic microorganisms in active form reaches 108 CFU/cm3. It is proposed to use the “Lactomix KM” stabilization system, which is usually used in the production of fermented milk products.

The article provides an overview of innovative technologies for the production of BAAs from the fat of marine pinnipeds. In ancient times they said: “Let food be medicine, and medicine – food” (Hippocrates). The possibility and necessity of creating and using BAAs - biologically active food addidives to maintain human health are based on this postulate of Hippocrates. Since ancient times, mankind has understood the importance of proper nutrition for health and longevity. Accumulating experience in the use of certain products in food and their importance for maintaining and preserving human health, researchers have found new food substances with biological activity that can be used to treat and prevent diseases [1, p. 225-227]. Biological activity of seal fat that inhabits the Arctic territories of Yakutia has been studied. Seals inhabit this zone in large quantities, while causing significant damage to the industrial fishing of this territory. According to the Federal Agency for Fishery, the industrial quota for seal production in this zone can be up to 3,000 heads per year. This is an economic justification for the introduction of technology for processing products obtained from marine mammals to obtain raw materials for the food, medical and cosmetic industries. The extreme climatic conditions of Arctic Yakutia determine the rich biochemical composition of seal subcutaneous fat. The fatty acid content in the seal subcutaneous fat confirms its uniqueness as a raw material for the dietary supplement “Akibol” with a high content of PUFA.

The article considers the research on the development of bread with added new ingredient – French willow. French willow or Ivan-tea is widespread throughout the Ural region. It contains all the vitamins and microelements necessary for the body, which help to reduce oxidative processes. The components of Ivan-tea have immunostimulating properties, they affect the processes of hematopoiesis and the activity of vitamins in the body and are of great importance in blood diseases, atherosclerosis, and some types of tumors. The development will expand the range of bread offered to the population in stores. And create new types of bread, including functional ones [1, 2, 3]. The production of bread samples consisted of the following stages: raw material preparation, ingredient addition, dough kneading, dough maturation, kneading, baking, cooling and product inspection. Five bread samples were produced and analyzed. Samples No. 1 and No. 2 were made using live sourdough, while samples No. 3 and No. 4 used baker's yeast. The control bread sample was made in accordance with GOST R 31807-2018, which is valid in the Russian Federation. Bakery products from rye flour and a mixture of rye and wheat flour. General specifications. French williw infusion was added to four samples (No. 1, No. 2, No. 3, and No. 4) in amounts of 100 and 200 ml. The organoleptic properties of all samples were assessed according to GOST 31807-2018. The physicochemical properties included porosity (GOST 5669-96), acidity (GOST 5670-96), and humidity (GOST R 58233-2018). The research showed that the best sample was wheat-rye bread (No. 2), prepared with sourdough and 200 ml of fireweed infusion. The appearance of the product corresponded to the baking form - tin. The surface was without cracks and tears. Color was light brown. Taste and smell were typical for this type of product with notes of fireweed. Porosity was developed, without compaction. Traces of unmixed particles were not found. The humidity of the experimental sample No. 2 was 47%, the acidity index was 0.5° higher than the norm and was - 3.5°. The porosity index was 68.82%. Thus, it can be assumed that the French willow infusion affects the physicochemical properties of bread products (increasing porosity by 0.82%). And it affects the organoleptic properties of the samples, improving the taste and appearance of the product.

Seed crushing is one of the main technological operations [1] in the process of obtaining essential and fatty oils, on which their yield and quality depend [2]. Improving the process of preparation for the extraction of coriander seeds by selective cryodesintegration and creating technological lines of various productivity is of significant importance and relevance. However, modern methods and means of cryodesintegration of coriander seeds require research and improvement. The process of seed grinding is divided into three phases [3]: elastic deformation, which occurs from the beginning of the action of the applied force on the material being ground until the elastic limit is reached and is accompanied by compaction and compression of the structural aggregates of the seeds; plastic deformation, which occurs from the moment of the beginning of the shift of individual elements of the material relative to each other and is characterized by the relative displacement of the structural aggregates of the seed kernel, as a result of which the material is compacted and flattened; destruction of the material with the formation of a free surface of particles. The main parameter of the process of cryodesintegration of coriander seeds is subject to theoretical justification - normal pressure, leading to deformation, where the pressure on the seeds exceeds their tensile strength, but there is no appearance of oil on the surface of the opened seeds. This prevents oil loss and contamination of the working parts, especially with essential oils. Monitoring theoretical studies of the grinding process allows us to talk about the need to develop a mathematical description of this process.
