We set out to develop an algorithm for automated control of the technological process of 3D printing with chocolate mass. To that end, an analysis of the existing algorithm for 3D printing of food products with chocolate mass and chocolate icing was carried out. The causes of defects were also considered. An algorithm for an automated control and adjustment system applicable to this type of 3D printing is proposed. The main sensor is a vision system, whose main task consists in recognizing and evaluating the state of the top printing layer. On the basis of this information, the speed of applying the material of the next layer is adjusted. The implementation of the proposed control algorithm can optimize the process of printing with chocolate and icing mass, save the operator's time, reduce the amount of defective products, and achieve the optimal speed for obtaining a three-dimensional product. The results of the work will be used in the process of implementing an automated control system for the process of 3D food printing with chocolate using technical vision.

This paper considers requirements for main motion drives. A mathematical description of a dualmass system interconnected through an elastic replacement belt is provided. A study was made of the influence of elasticity on the dynamics and accuracy of maintaining the speed of the main motion drive of a machine. When modeling a control system for the main motion drive of a lathe machine, taking the elastic connection of the belt without a correction factor into consideration, an error associated with the speed in the steady state under a change in the resistance moment arises. The resistance moment depends on the radius, the workpiece material, and the settings of the longitudinal and transverse drives, such as depth of cut and feed rate. The control system for the main motion drive of a lathe, developed in the MatLab and Simulink environment, taking the belt elasticity with a correction factor into account, ensures high static characteristics of the drive.

Authors: Kruchynenko O. V.
Published: October 2023

This review presents data on the most common causative agents of protozooses, helminthiases, and ectoparasitic diseases of rabbits (Oryctolagus cuniculus, Linnaeus, 1758), which are of interest to veterinarians. Modern methods of diagnosing parasitic diseases in rabbits have been determined. Chemotherapeutic drugs available on the world pharmaceutical market for therapeutic and preventive treatments in rabbits are listed. The main causative agents of protozoan, helminthic, and ectoparasitic diseases of rabbits are considered, considering the modern systematic position of parasites. The features of the distribution of parasitic diseases in Ukraine and the world, according to the data of well-known scientists in the field of veterinary parasitology, are briefly given. Information on the specifics of the use of antiparasitic drugs in the case of animals affected by protozooses, helminths, and ticks is summarized. The work briefly provides information on the most common medicines and chemical combinations that are the active ingredients of these drugs (their chemical names existing in different countries, synonyms, and main pharmacological properties). Information on the dosage and features of the use of antiparasitic agents in the case of rabbit diseases is given following the data of modern scientific literature and the relevant recommendations for their industrial use. During the inspection, it was established that rabbits are most often affected by eimeriosis (coccidiosis). Currently, 15 species of Eimeria spp. have been identified. Young animals (2–6 months) are most susceptible to eimeriosis. The peak of infestation in the territory of Ukraine falls in the spring-summer period. It was found that P. ambiguus is most often detected among helminthiases in rabbits in our country. Rabbits aged 1 to 2 years are most susceptible to these helminths, and the peak of infestation occurs in January. In rabbits, psoroptosis is one of the most common acaroses, the causative agent of which is ticks of the P. cuniculi species. The purpose of this work was to show the current state of rabbits' most common parasitic diseases on the territory of Ukraine and in the world in general, highlight the existing antiparasitic drugs, and summarize information on their use. It has been established that animals with encephalitozoonosis are the most difficult to diagnose and treat. At the same time, there is a wide range of coccidiostats and coccidiolytics for treating rabbits affected by eimeries. For the infestation of animals with helminths, it is appropriate to use benzimidazoles and ivermectins. In the case of acaroses, ivermectin and fungicidal-acaricidal ointments remain effective drugs. The analysis of literary sources will allow for the expansion of the already available data on the spread, prevention, and treatment of parasitic diseases in rabbits. The given information will help ensure the rabbits' veterinary well-being on Ukraine's territory.

Authors: Sharan O.
Published: October 2023

To increase the sexual activity and sperm quality of rams during the period of sexual rest, it is necessary to increase the consumption rates of vitamins and microelements to the level of the mating season. The aim of the work was to find out the effect of feeding a liposomal vitamin-mineral supplement on the quality parameters of ram sperm during the period of sexual rest. The experiment was conducted on 12 clinically healthy Texel rams, aged 2–4 years, during the period of sexual rest (March–May). Animals were divided into two groups: control and experimental, 6 heads each. The control rams received the basic diet, the animals of the experimental group were individually added to the combined feed for 45 days with a feed additive in the form of a liposomal emulsion, which included: vitamins A, D3, E, C and zinc gluconate. After the end of supplement feeding, ejaculates were collected from the rams for research. The motility, kinetic indicators of sperm, the activity of succinate dehydrogenase (SDH) and cytochrome oxidase (CO) in sperm, as well as the activity of antioxidant protection enzymes superoxide dismutase (SOD), glutathione peroxidase (GPO) and catalase (CAT) were determined. It was established that feeding liposomal vitamin-mineral supplement to rams during the period of sexual rest significantly (P < 0.05) increases sperm activity, their kinetic indicators: curvilinear (VCL), straight-line (VSL) and average speed (VAP) of sperm movement (P < 0.05–0.001), the activity of enzymes – markers of the fertilizing capacity of SDH and CO sperm (P < 0.05–0.001). At the same time, there was a significant (P < 0.05) decrease in the activity of SOD with a simultaneous significant (by 23.3–25.0 %) increase in the activity of GPO and CAT (P < 0.01). Higher indicators of the quality of ejaculates of rams under the influence of vitamins A, D3, E, C and zinc gluconate indicate the possibility of obtaining high-quality sperm from breeding rams during the period of sexual rest.

Mineral elements increase the capacity of organisms for their adaptation to abiotic factors and improve the biological value of animal products. The aim of the experiment was to study the effect of magnesium citrate on the content of total protein in the tissues of the whole organism, the content of soluble protein fractions in hemolymph, and catalase activity. The research was conducted on Carpathian honey bees. They were selected in the apiary at the Institute of Animal Biology of the National Academy of Sciences. The research was conducted in two stages. The first stage of the work was carried out on 5 groups of bees under the conditions of a laboratory thermostat for 20 days. Bees of the control group were fed daily with 1 ml of 50 % sugar syrup (SS) and 1 ml of H2O; group II – 1 ml of SS + 1 ml of 0.4 mg Mg/l nanocitrate; group III – 1 ml of CS + 1 ml of 2 mg Mg/l citrate; group IV – 1 ml of SS + 1 ml of 3 mg Mg/l citrate; group V – 1 ml of SS + 1 ml of 4 mg Mg/l citrate. The second stage of the study was conducted on four groups of bees and lasted 30 days. Bees of the control (I) group were fed daily with 1 ml of 50 % SS and 1 ml of H2O; group II – 1 ml of SS + 1 ml of 0.04 mg Mg/l citrate; group III – 1 ml of SS + 1 ml of 0.02 mg Mg/l citrate; group IV – 1 ml of SS + 1 ml of 0.01 mg Mg/l citrate. At the first stage, a decrease in α1-globulins in the hemolymph of bees of the III – V groups was established. The content of β-globulins increased in the II (P < 0.001), III (P < 0.01), IV (P < 0.001) and V (P < 0.001) experimental groups. The content of γ-globulins decreased in hemolymph of II (P < 0.001) and III (P < 0.01) groups. At the second stage, a decrease in α1–globulins was observed in the hemolymph of bees of the II, III and IV experimental groups compared to the control. The content of α2-globulins was significantly lower in the hemolymph of bees from IV group, and the content of β-globulins was higher in the hemolymph of the bees. An increase in the content of γ-globulins was established in II (P < 0.05), III and IV (P < 0.01) experimental groups. High catalase activity was observed in the hemolymph of bees of all experimental groups (P < 0.001). The highest catalase activity was registered in bees of IV group. The use of 0.01 mg of Mg citrate in addition to sugar syrup feeding changed the ratio of individual hemolymph protein fractions. The relative content of albumin and β-globulin decreased and α2 and γ globulin content increased. An increase in the relative content of α1 and a decrease in β- and γ-globulins in the hemolymph of honey bees of the research groups were caused by Mg citrate in a dose of 0.04 mg.
The Impacts of Covid-19 on the Digital Transformation of the Brazilian Automotive Sector from the Perspective of Consumers and Industry Executives
Authors: Silva Bruno Campos Pinto
Published: October 2023

The aim of this article is to provide an analysis of the potential impacts brought about by the COVID-19 pandemic on the digital transformation process within the automotive industry, from the perspectives of both consumers and industry executives. Qualitative analysis was conducted in conjunction with exploratory research. This involved drawing upon a theoretical framework related to disruption, digital transformation, with a specific focus on the industry under study. The research also incorporated desk research using data collected from market studies, and an exploratory survey conducted online, involving 67 industry executives. The study analyzed both convergent and divergent factors from desk research and exploratory research to understand if the executives held the same perceptions as what had been explored and discovered within the theoretical framework and secondary data. One of the primary challenges in social research, including recent studies on innovation, is the complexity of human relationships and leadership within organizations in general. Researchers in the fields of Management and Innovation often struggle with reducing systemic complexity when attempting to comprehend how consumers and executives in a specific industry perceive reality. It becomes evident that, even in the absence of statistical correlations between variables, leaders perceive realities that drive their actions and reactions within their environment. Studies on this subject have been relatively underutilized in Brazil, both in practical and theoretical realms, regardless of the industry sector. This research could be applied to any industry, even those traditionally considered as non-innovative.
O “batedor de si": uma proposta para a construção de uma narrativa cívica para o homem moderno
Authors: Schier Ubirajara Theodoro
Published: October 2023

Este artigo explora o modo de vida cínico como proposta para a elaboração de uma narrativa cínica para a libertação do homem moderno. Segundo Adorno e Horkheimer, a relação entre a sociedade e o homem moderno pode ser considerada uma relação de servidão do homem à sociedade. Nessa relação, a liberdade individual cedeu ao propósito utilitarista imposto pela sociedade ao homem moderno. O cinismo, por sua vez, representa um modo de vida oposto, em que o indivíduo é plenamente livre e não submisso socialmente. Apesar de representar uma utopia para os tempos atuais – a ideia da libertação plena do indivíduo – verificou-se que existem pontos não explorados do modo de viver cínico que podem servir para a recuperação gradual da liberdade individual do homem moderno. Esses pontos são apresentados como proposta para a construção de uma narrativa cínica para libertação do indivíduo encarcerado pela sociedade moderna.
Ömer Seyfettin'in Milliyetçilik Anlayışının Bağlamı, İçeriği ve Temel Motifleri
Authors: KUTLU Aydoğan
Published: October 2023

Osmanlı İmparatorluğu’nun yıkılış döneminde, farklı ideolojilerin rekabet içinde farklı siyasal, toplumsal, kültürel ve hatta iktisadi çözüm önerileri geliştirdiği bir bağlamda yazan Ömer Seyfettin, 20. yüzyıl boyunca en önde gelen hikâyecilerden biri olmuştur. Fazlasıyla döneminin koşulları içinde düşünen ve yazan bir yazarın niçin Cumhuriyet Türkiyesi’nin en önemli, en saygın yazarlarından biri haline geldiği sorusunu kalkış noktası alan bu çalışma, yanıtın edebiyattan çok siyasette, daha açıkçası yazarın milliyetçi ideolojisinde yattığını kabul etmektedir. Bu bağlamda Ömer Seyfettin’in milliyetçilik anlayışını ele alan çalışma, onun aslında dönemsel ihtiyaçlar içinde beliren kavramlarının ve temalarının kendi iç bütünlüğünü ve çelişkilerini araştırmaktadır. Bu bağlamda tarihsel arka planda Osmanlı İmparatorluğu’nun geçirdiği dönüşüm ve Balkan milliyetçiliklerinin gelişerek zafere ulaşması yer alırken; onların tepkisel yansıması olarak ırka ve kana vurgu yapan, devlet karşısında bireyi önemsizleştiren, vatan kavramı belirsiz ama milletler arasında Sosyal Darwinist bir rekabeti ve her milletin kendi mefkûresini gerçekleştirmek için mücadelesini meşrulaştıran bir milliyetçilik vücut bulmaktadır. Bu milliyetçilik anlayışının kendi çelişkilerine ışık tutabilmek için ise kadın, din ve dil gibi kamusal tartışmalardaki yaklaşımları incelenmektedir. Bu konular, farklı ideolojilerin kesişim alanında yer aldığı için ideolojik savrulmaların daha net görülmesini sağlamaktadır. Nihayetinde çalışma, Ömer Seyfettin’in milliyetçiliğinin özgün vurgularına ve çelişkilerine karşın, milliyetçiliği geniş kitlelere basitleştirerek sunmayı başardığı için kanonik olmayı başardığı savıyla sona ermektedir.

Eğitim, millî aidiyet duygusunun gelişimine katkı sağlamakla beraber toplumların geleceğini tayin etmek yönüyle bir fener görevi görmektedir. Bu görev, Osmanlı Devleti’nin klasik döneminde hem doğuyu hem de batıyı aydınlatırken, değişen dünya düzeni ile modernleşme ihtiyacını da beraberinde getirmiştir. Nitekim Osmanlı Devleti, eğitimin öneminin her zaman farkında olmuş ve artan savaş mağlubiyetlerini kapatmak amacıyla XVIII. yüzyıldan itibaren bu alanda ıslahatlar yapmaya da özen göstermiştir. Atılan adımlarla eğitim kademeli hale getirilmeye çalışılmıştır. Bu kademelerden birisi de Sultan II. Mahmud zamanında açılmasına karar verilen rüşdiyeler olmuştur. Açılan bu mekteplerin amacı, daha önceden açılmış olan Mühendishanelere daha donanımlı talebe yetiştirmektir. 1869 Maârif-i Umûmiye Nizâmnâmesi ile nüfusu 500 haneyi aşan yerlerde rüşdiyelerin açılması zorunlu kılınarak, taşrada da yaygınlaşması sağlanmıştır. Taşrada açılan rüşdiyelerden birisi de Malkara’da açılan Malkara Mekteb-i Rüşdiyesi’dir. Bu çalışmada Malkara Mekteb-i Rüşdiyesi arşiv belgeleri ve maârif salnâmelerine göre incelenmiştir. Malkara’da açılan bu rüşdiye, kazada bulunan sakinler tarafından yapılmış olup, bölgenin eğitim ve öğretime vermiş olduğu önemi göstermesi bakımından da önem arz etmektedir.

Published: October 2023

The robotic arm is a type of statistical robot with a limited range of movement. Robotic arms are generally within the scope of Cartesian coordinates, according to the specified link length. The development of robot technology leads us to continue to upgrade soft computing. Intelligent systems in robots can improve good navigation detection systems or carry out the operator's tasks. On the other hand, using a camera is an important part of finding clear information about objects or capturing the environment around the robot. In this research, we implemented an intelligent system and computer-based camera on a 4-DoF robotic arm system. This robotic arm consists of a computer as the main processor, a microcontroller to adjust the joint angle, additional electronics, and a camera to detect objects and classify them by color. The colors used are red, green, and blue. The learning process uses these colors using Learning Vector Quantization (LVQ). The implementation of LVQ also carries out pre-processing, training, and testing stages. In the experiments that have been carried out, the robotic arm successfully navigates toward the target object and moves the object using the Trajectory Planning method. This computing process is done on a computer and connected to the robot arm's microcontroller. The experiment was carried out 60 times, and the success rate was 95%. Overall, the robot successfully picked up objects and grouped them by color.
Determinants of corporate disclosures: An empirical test of political economy theory
Authors: Priyadarshanie W A N , Yusoff Siti Khalidah Md , Azam S. M. Ferdous
Published: October 2023

The principle objective of this study was to employ political economy theory in order to examine the determinants that impact the corporate disclosure of listed companies in Sri Lanka. Data was gathered from 122 companies over a period of eight years, from 2012 to 2019. Corporate disclosures of Sri Lankan listed corporations were analysed using Partial Least Square Structural Equation Modelling (PLS-SEM). Determinants of corporate disclosures have been examined in light of political economy theory, namely legitimacy, isomorphic effects, and stakeholder power. The amount of corporate disclosure was quantified using an unweighted index in this research. This study found that legitimacy, isomorphic influences, and stakeholder power are positively associated with the level of corporate disclosure. Findings suggest that managers use corporate disclosures as a strategy to legitimize themselves, manage stakeholder power, and cope with isomorphic influences. This is the first research so far to utilize the PLS-SEM to identify the determinants of corporate disclosures. Considering emerging economies across the globe, the findings of the study provide valuable insights for companies to understand how political economy theory affects the level of corporate disclosures.

Banal Security: Queer Korea in the Time of Viruses
Authors: Gitzen Timothy
Published: October 2023

The decades-long fear of South Korean national destruction has routinized national security and the sense of threat. In present day South Korea, national security includes not only war and the military, but national unity, public health, and the family. As a result, queer Koreans have become a target as their bodies are thought to harbor deadly viruses and are thus seen as carriers of diseases. The prevailing narrative already sees being queer as a threat to traditional family and marriage. By claiming that queer Koreans disrupt military readiness and unit cohesion, that threat is extended to the entire population. Queer Koreans are enveloped by the banality of security, treated as threats, while also being overlooked as part of the nation. What does it mean to be perceived as a national threat simply based on who you would like to sleep with? In their desire to be seen as citizens who support the safety and security of the nation, queer Koreans placate a patriarchal and national authority that is responsible for their continued marginalization. At the same time, they are also creating spaces to protect themselves from the security measures and technologies directed against them. Taking readers from police stations and the galleries of the Constitutional Court to queer activist offices and pride festivals, Banal Security explores how queer Koreans participate in their own securitization, demonstrates how security weaves through daily life in ways that oppress queer Koreans, and highlights the work of queer activists to address that oppression. In doing so, queer Koreans challenge not only the contours of national security in South Korea, but global entanglements of security.
The Mechanism of Optimal Development of the Regional Spatial and Sectoral Structure in the Conditions of Transition to the Digital Economy

Published: October 2023

In article approaches to justification of the mechanism of optimum development of regional spatial-industry structure in the conditions of transition to digital economy are generalized theoretical-methodological. In the conditions of the next multidimensional crisis of a world economic system caused by competitive wars and local wars with use of lethal weapon the frailty of the existing economic theories at their checking is shown by order and chaos. It indicates the need of application of the basic theory for economy for which the existing economic theories are the first and second derivatives with the specific set of the principles of development. As such basic theory the chaotic theory of inflation of economic space (CTIES) as an analog of the chaotic theory of inflation of the Universe which is the basic theory in a modern general scientific picture of the world can serve in economy. The author offers based on CTIES use of the principles of sustainable development as the transitional stage to a noonomy, at the same time needs the solution of problems of balancing of developments on the chosen parameters by means of application of a triad of matrixes paradigmatic, management and matrixes of technological effectiveness within trinities «society – ​economy – ​ecology», «organization – ​motivation – ​informatization» and «labor instrument – ​objects of the labor – ​work» respectively. The most acceptable methodology for this purpose is the methodology based on the geometrical theory of optimal management. Such approach assumes work with Big Data, Data Science, Data mining, Machine learning, etc. characterizing transition to digital economy and, respectively, to researches on the basis of the Fourth paradigm of science (Science 4.0, E-science).
Circular Economy – Circular Visions of the Future
Authors: Fontana Karine A. , Yerznkyan Bagrat H.
Published: October 2023

Interest in the circular economy (CE) is growing in scientific circles, at the state level, as well as among businesses. At the same time, the question of what the circular world will be like remains insufficiently studied and even formulated. Scientific research is focused on the analysis of circular strategies (R-strategies) in the context of sustainable development, exploring the benefits of CE and the barriers to achieving it. At the same time, R-strategies without reference to the images of the future can interfere with the achievement of the goals set and the solution of a number of environmental problems. The article presents images of a circular future and gives a definition of CE, without which a different understanding of the concept is inevitable, leading to the introduction of different indicators for measuring progress in achieving circular goals. Main findings: CE is an evolving concept, which explains the lack of a single definition. It should reflect the images of the future, which will create the basis for the development of a unified system of indicators to measure the degree of achievement of goals and compare them at the international level. Images of the future must be interpreted as a process of improvement, because they can be transformed. The study used general scientific methods of system analysis, abstraction, synthesis, a review of Russian and foreign scientific literature, data from the official websites of the government of the Russian Federation was carried out to determine the CE, its determinants in order to consolidate research on this topic. Such a review is a reproducible, scientific and transparent method of identifying a research area. For this, we used the data presented in the bibliographic databases eLibrary.ru, Google Scholar, ScienceDirect. The results will find a response in the scientific, political, business circles for a better understanding of the CE, developing of strategies for the transition to it, forming of images of the future; serving as a basis for developing indicators and measuring the progress of such actions.
Evolution of Views on the Socio-Economic Role of Information Technology – the Example of the 60-Year History of Central Economics and Mathematics Institute of Russian Academy of Sciences
Authors: Ilmensky Mikhail D. , Parinov Sergey I.
Published: October 2023

The history of the information technology (IT) development at CEMI RAS and the rethinking of the IT role and associated expectations that has occurred over 60 years in this organization can be an illustration of the evolution of views in the scientific community regarding the socio-economic potential of IT. Over the years of its research work, CEMI RAS worked out the most effective way to use almost all major modifications of computers in scientific research, and also carried out the work related to the development of information and communication technologies, including the Internet. Gradually, views on the IT role as a tool for scientific research evolved into an understanding of the complex impact of IT on socio-economic processes, which has the form of widespread digitalization of socio-economic activities. Under these conditions, one of the key IT-related areas of research and development is the creation of a concept for digitalization of coordination mechanisms, the improvement of which affects the entire socio-economic system. The proposed study briefly presents the main milestones in the use and development of IT over the 60 years of CEMI existence and substantiates a qualitatively new task of using and developing IT to improve methods for coordinating scientific research. The rationale for this task is presented using the example of research activities, but the overall long-term goal of these studies is to develop the concept of digital infrastructure and corresponding institutional structures that will ensure better coordination and act as catalyst for the country's development in all major areas of economic activity.

Authors: Skretkowicz Yvette , K. Perret Jens
Published: October 2023

Globally, unhealthy diets have a significant impact on people's risk of disease and mortality, so the German Ministry of Nutrition and Agriculture also focuses on healthier and balanced diets in its reduction and innovation strategy. By means of the Nutri-Score, the nudging principle is used to provide consumers with additional nutritional labelling and to encourage the purchase of healthier foods. The aim of this study is to investigate the effectiveness of visual nudging in FMCGs, i.e., the food industry, in the form of the Nutri-Score on consumers' purchase decisions and to validate its robustness with respect to demographic factors. For this purpose, an online survey was conducted with 294 participants leading to a total number of up to 3,528 observations regarding their purchase intention of selected products. A logistic regression analysis showed that the purchasing behaviour changed with the insertion of the Nutri-Score per se and with subjects avoiding negatively rated products and preferring positively rated ones. It was further shown that these effects persist regardless of participants’ demographics.

KARAKTERISTIK ANALOGI SISWA SEKOLAH DASAR DALAM PENGAJUAN MASALAH LUAS DAERAH
Authors: Eksanti Aulia Risa , Amir Mohammad Faizal
Published: October 2023

This study aims to identify the characteristics of elementary school students' analogies in proposing area problems. The method used in this research is descriptive qualitative using a case study approach. The characteristics of analogy in the submission of area problems can be categorized into three: (1) Identical-reformulation is rearranging the elements in the problem structure in ways that do not change the nature of the problem. (2) Identical-different-reconstruction is modifying and maintaining some elements of the form in the initial problem so that the resulting problem looks slightly different. (3) Different-imitation is changing and adding new shape elements that are not in the initial problem to produce a different problem. The results of the research showed that the characteristic most often found in students is imitation, where the problem produced is different from the initial problem given. So the different imitation characteristics that appear most often correspond to replacement characteristics, namely the problem posing product based on the initial problem or source problem by changing the context of the problem, namely changing the shape of the cake slice.

Preliminary observations showed that 27.7% of students received a score above 75 and 72.3% received a rating below 75. The minimum score for the exam was 75, which is the average grade. Many factors can contribute to poor student learning outcomes, including the role of teachers as instructors and their influence on students in creating and using inappropriate learning strategies. An alternative that can be developed on a model with learning is to use a mind mapping defence model. This survey aims to find out how much influence it has found on the mind mapping defense model with the help of power points.  The type of quantitative research used in this study is the design of a single group pretest-posttest. The test results are known to have a thitung value of 3.27. Thitung values are matched to with Table values with a significant upgrade of a=0,05 and obtained Table Values of 2.063. Thitung Values are derived that is greater than Table Value (thitung = 3.27 > ttable = 2.063 then Ha is accepted, that is, using the learning model of Mind Mapping and PowerPoint media, the student's learning results can be influenced.

The gut microbiota of wild birds is sensitive to external environmental factors. Under the stress of cold temperatures in winter, seed-eating birds residing in stable habitats for a prolonged period experience gradual deterioration of dietary resources as time progresses. Investigating the dynamics of the gut microbiota of endangered birds throughout the wintering phase can offer an essential foundation for designing specific conservation measures. In this study, fresh faecal samples were collected from populations of great bustard Otis tarda dybowskii in stable wintering habitats during early, mid, and late winter. The gut microbiota of the great bustard at different time points was comparatively analyzed using high-throughput sequencing of the 16S rRNA gene. The results showed that the gut microbiota of overwintering great bustard comprised primarily 4 phyla: Firmicutes (80.13%), Bacteroidetes (10.54%), Actinobacteria (6.86%), and Proteobacteria (1.23%), accounting for 98.75% of the total microbial abundance across all samples. While there were no significant differences in the gut microbiota during the early and mid-winter periods, significant changes occurred during the late wintering period. There was a significant decline in cofactor and vitamin metabolism, along with lower bacterial richness indices. In the late wintering period, the great bustard population in the wild may face increased survival pressures. Providing food supplementation before spring migration could potentially play a crucial role in saving this endangered species.
The structure-function paradigm reshaped by intrinsically disordered regions
Authors:   , Gui Tianshu
Published: October 2023

The classic structure-function paradigm has long been considered a cornerstone of protein biology, as it posits that the specific functionality of a protein is determined by its unique three-dimensional (3D) structure. However, the recognition of intrinsically disordered region (IDR) challenges the notion that a well-defined structure is necessary for protein function and has redefined the traditional structure-function relationship. In this thesis, we first depicted the interaction profiling between transcription factor FOXO4 with co-factor β-catenin, facilitated by the FOXO’s IDR, which highlights the role of IDR as a signaling hub. IDR can also direct biomolecular condensates which play a prominent role in biology. Leveraging the interaction profiling between FOXO4 and β-catenin, a FOXO4-derived short peptide was designed to inhibit IDR-mediated β-catenin condensation. Furthermore, we propose a "monomer saturation" model to elucidate the mechanism through which co-factor derived peptides can perturb condensates, which can be helpful for the potential drug discovery. Lastly, we demonstrate another function of IDRs in regulating the mobility of FOXO proteins within the nucleus, which might contribute to the isoform specificity of FOXO proteins. Future work is required to fully comprehend this intriguing observation mediated by IDRs. Finally, the functional versatility of IDRs highlights the significance of IDRs in biological processes, which reshape the classic structure-function paradigm.
Promiscuous Kinds and Individual Minds
Authors: Corns Jennifer
Published: October 2023

Promiscuous realism is the thesis that there are many equally legitimate ways of classifying the world’s entities. Advocates of promiscuous realism are typically taken to hold the further the- sis, often undistinguished, that kind terms usefully deployed in scientific generalisations are no more natural than those deployed for any other purposes. Call this further thesis promiscuous nat- uralism. I here defend a version of promiscuous realism which denies promiscuous naturalism. To do so, I introduce the notion of a promiscuous kind: a kind that is maximally usefully referenced in predictive and explanatory generalisations, none of which are scientific generalisations. I first defend the claim that pain is a promiscuous kind before extending these considerations to everyday mental kinds more generally. I draw on further reflections from both everyday life and contem- porary psychology to make credible the novel suggestion that our everyday theory of our minds is for the explanation and prediction of individuals. Combined with the complex idiosyncrasy of individual minds, this suggested aim of everyday theory gives us reason to think that promiscuity is prevalent among everyday mental kinds.

Published: October 2023

Introduction: Genome-scale metabolic models (GEMs) are organism-specific knowledge bases which can be used to unravel pathogenicity or improve production of specific metabolites in biotechnology applications. However, the validity of predictions for bacterial proliferation in in vitro settings is hardly investigated.

Methods: The present work combines in silico and in vitro approaches to create and curate strain-specific genome-scale metabolic models of Corynebacterium striatum.

Results: We introduce five newly created strain-specific genome-scale metabolic models (GEMs) of high quality, satisfying all contemporary standards and requirements. All these models have been benchmarked using the community standard test suite Metabolic Model Testing (MEMOTE) and were validated by laboratory experiments. For the curation of those models, the software infrastructure refineGEMs was developed to work on these models in parallel and to comply with the quality standards for GEMs. The model predictions were confirmed by experimental data and a new comparison metric based on the doubling time was developed to quantify bacterial growth.

Discussion: Future modeling projects can rely on the proposed software, which is independent of specific environmental conditions. The validation approach based on the growth rate calculation is now accessible and closely aligned with biological questions. The curated models are freely available via BioModels and a GitHub repository and can be used. The open-source software refineGEMs is available from https://github.com/draeger-lab/refinegems.

Exact land cover (LC) map is essential information for understanding the development of human societies and studying the impacts of climate and environmental change. To fulfill this requirement, an optimal parameter of Random Forest (RF) for LC classification with suitable data type and dataset on Google Earth Engine (GEE) was investigated. The research objectives were 1) to examine optimum parameters of RF for LC classification at local scale 2) to classify LC data and assess accuracy in model area (Hefei City), 3) to identify a suitable data type and dataset for LC classification and 4) to validate optimum parameters of RF for LC classification with a suitable data type and dataset in test area (Nanjing City). This study suggests that the suitable data types for LC classification were Sentinel-2 data with auxiliary data. Meanwhile, the suitable dataset for LC classification was monthly and seasonal medians of Sentinel-2, elevation, and nighttime light data. The appropriate values of the number of trees, the variable per split, and the bag fraction for RF were 800, 22, and 0.9, respectively. The overall accuracy (OA) and Kappa index of LC in model area (Hefei City) with suitable dataset was 93.17% and 0.9102. In the meantime, the OA and Kappa index of LC in test area (Nanjing City) was 92.38% and 0.8914. Thus, the developed research methodology can be applied to update LC map where LC changes quickly occur.
