Authors: Болаев В.К. , Захаров В.А. , Пустовой В.Ф.
Published: July 2024

В условиях становления рыночных отношений в животноводстве происходит объективный процесс сокращения в стране популяции двугорбых верблюдов. За период с 1991 по 2020 год численность верблюдов уменьшилась с 9,5 до 5,7 тыс. голов на 40,0 %. При этом, особую тревогу вызывает снижение до минимальных размеров поголовья, наиболее ценной в селекционном отношении калмыцкой породы верблюдов, с 6,6 до 4,3 тысяч голов, то есть более чем в 1,5 раза.Учитывая, что верблюды этой породы являются непревзойденными в популяции по своим экстерьерным, продуктивным и рабочим качествам, гармоничности сложения и нарядности форм, в статье ставится задача принять неотложные меры по сохранению генофонда калмыцких верблюдов в оставшихся племенных хозяйствах Астраханской области и Республики Калмыкия.

In the conditions of the formation of market relations in animal husbandry, there is an objective process of reducing the population of Bactrian camels in the country. During the period from 1991 to 2020, the number of camels decreased, from 9.5 to 5.7 thousand heads by 40.0%. At the same time, the decrease in the livestock to the minimum size, the most valuable, in terms of breeding, Kalmyk breed of camels, from 6.6 to 4.3 thousand heads, that is, more than 1.5 times, is of particular concern.Considering that the camels of this breed are unsurpassed in the population in terms of their exterior, productive and working qualities, harmony of build and elegance of forms, the article sets the task of taking urgent measures to preserve the gene pool of Kalmyk camels in the remaining breeding farms of the Astrakhan region and the Republic of Kalmykia.

Use of genetic markers in selection of thoroughbred horses
Authors: Сулейманов О.И.
Published: July 2024

Одним из факторов, сдерживающих улучшение работоспособности лошадей чистокровной верховой породы России, является низкая интенсивность отбора жеребцов и кобыл в производящий состав.При проведении отбора преимущество отдаётся импортным лошадям. Использование в селекции международного генофонда породы, приводит к увеличению генетического полиморфизма в популяции лошадей, рожденных в России. Однако влияние генетического полиморфизма на работоспособность изучена недостаточно.Традиционно, при отборе в производящий состав генотип лошадей оценивается по родословной. Такая оценка включает в себя линейную принадлежность, уровень инбридинга, характеристику племенной ценности выдающихся предков. Однако, зоотехнический метод оценки генотипа по родословной не всегда приводит к прогнозируемым результатам качества потомства.Современная генетическая наука делает возможным и целесообразным дополнить зоотехническую оценку генотипа по родословной изучением генома животного.В этой связи, в проводимых исследованиях предпринята попытка изучить генетическую карту лошадей производящего состава по STR-локусам микросателлитов ДНК, с целью выявления возможной зависимости скакового класса лошадей от STR-локусов.Изучение генотипической характеристики лошадей актуально не только для научно-исследовательских работ, но и для практического применения генетических маркеров в селекционно-племенной работе.

Low level of selection of stallions and mares is one of the factors that slow down of race class of the Russian Thoroughbreds. In process of selection, preference is given to imported horses. The use in breeding of the imported animals increases of genetic polymorphism in the population of horses born in Russia. But the relationship between genetic polymorphism and race class has not been studied enough. Usually when selecting a breeding stock, the genotype of a horse is analyzed by its pedigree. Such analyze includes the linebreeding, the level of inbreeding and breeding value of outstanding ancestors. However, such method of assessing the genotype by pedigree does not justify prognosis for offspringюModern genetic science makes it possible to complement the method of pedigree analyze with the study of the animal genome.In this regard, an attempt was made to study the genetic markers of horses by STR loci of DNA microsatellites in order to find a possible connection between race class of horses and STR loci.The study of horses genotype is relevant for both science and practical use in breeding.

В статье приводятся результаты обследования трех групп лошадей в возрасте от 17 до 27 лет, содержащихся в аналогичных условиях городских конных клубов. Выявлено, что биохимические показатели сыворотки крови лошадей старшего возраста в основном укладываются в границы референсных значений, принятых за физиологическую норму. У возрастных лошадей из разных клубов установлены достоверно значимые отличия в содержании и активности отдельных субстратов и энзимов сыворотки крови. Очевидно, несмотря на схожесть условий содержания, кормления и ухода, на состояние обмена веществ возрастных животных оказывает влияние весь комплекс параметров их жизнеобеспечения.

The article presents the results of a survey of three groups of horses aged 17 to 27 years, kept in similar conditions of urban equestrian clubs. It was revealed that the biochemical parameters of the blood serum of older horses mainly fit within the boundaries of the reference values taken as the physiological norm. Age-related horses from different clubs showed significantly significant differences in the content and activity of individual substrates and enzymes of blood serum. Obviously, despite the similarity of the conditions of maintenance, feeding and care, the state of metabolism of aged animals is influenced by the whole complex of parameters of their life support.
NGT: Generative AI with Synthesizability Guarantees Identifies Potent Inhibitors for a G-protein Associated Melanocortin Receptor in a Tera-scale vHTS Screen

Published: July 2024

Commercially available, synthesis-on-demand virtual libraries contain upwards of trillions of readily synthesizable compounds for drug discovery campaigns. These libraries are a critical resource for rapid cycles of in silico discovery, property optimization and in vitro validation. However, as these libraries continue to grow exponentially in size, traditional search strategies that scale linearly with the number of compounds encounter significant limitations. Here we present NeuralGenThesis (NGT), an efficient reinforcement learning approach to retrieving compounds from ultra-large libraries that satisfy a set of user-specified constraints. Our method first trains a generative model over a virtual library and subsequently trains a normalizing flow to learn a distribution over latent space that decodes constraint-satisfying compounds. NGT allows multiple constraints without dictating how molecular properties are calculated, enabling versatile searches within virtual libraries. When NGT learned a policy reporting on compound bioactivity for the melanocortin- 2 receptor (MC2R) it prospectively identified potent and selective inhibitors in a three trillion compound library. NGT offers a powerful and scalable solution for navigating ultra-large virtual libraries, accelerating drug discovery efforts.
De novo determination of fucose linkages in N-glycans and the unusual N-glycans in bee venom

Published: July 2024

N-linked glycosylation are one of the most important post-translational modification of proteins. Fucosylated N-glycans are related to many biological processes and they are commonly used as biomarkers. However, determining fucose linkages in N-glycans remains challenging, and most of the fucose linkages, particularly the linkages in the antenna of N-glycans remain unidentified. In this work, a simple multi-stage tandem mass spectrometry method based on dissociation mechanisms was developed for the de novo determination of fucose linkages in N-glycans. Using collision induced dissociation (CID), fucose linkages in intact N-glycans (i.e., without permethylation, reduction, or other derivatization) extracted from pine nuts and human milk were identified. We demonstrate that fucose linkages in N-glycans, including the 1-3 linkage in the core of N-glycans, the 1-6 linkage in the core of N-glycans, the linkage in the (13) antenna of biantennary N-glycans, and the linkage in the (16) antenna of biantennary N-glycans, were identified through CID spectra. The procedure does not require the N-glycan standards, and the entire structural determination process is summarized in a flowchart for automation. Applications of this method to N-glycans extracted from bee venom led to the discovery of two unusual N-glycans, which are not expected to exist according to the current biosynthetic pathways.

We report the chemical conjugation of recombinant Adeno Associated Virus (rAAV) capsid with various functionalities, including proteins, using a bioorthogonal strategy. rAAVs were azido-coated or DBCO-coated by chemically modifying lysine or tyrosine residues. Lysine residues were modified using a phenyl isothiocyanate anchor, and tyrosine residues using either an aryldiazonium salt or a N-methyl luminol derivative. We demonstrate anchor- dependent labelling levels, as observed with biochemical assays and mass spectrometry. Strain-promoted azide-alkyne cycloaddition (SPAAC) was then implemented and evaluated on the rAAV to append functionalities such as fluorescein, biotin and carbohydrates to the azido- coated capsids. We confirmed the efficiency of the bioorthogonal reaction and observed a stronger reactivity with dibenzylcyclooctyne (DBCO) compared to bicyclononyne (BCN). The optimized SPAAC reaction was finally used to label the viral vectors with two relevant nanobodies targeting specific immune cell receptors (CD62L and CD45). In vitro transduction assays conducted with one rAAV-nanobody conjugate demonstrated the promising targeting properties of these chemically modified vectors. Thus, we anticipate that this strategy will positively impact the field of rAAV capsid engineering and contribute in tissue-specific targeting for the optimisation of gene therapy treatments.
Analytical Derivative Approaches for Vibro-Polaritionic Structures and Properties
Authors: Huang Xunkun , Liang WanZhen
Published: July 2024

Vibro-polaritons are hybrid light-matter states that arise from the strong coupling between molecular vibrations and the electromagnetic field in an optical resonator. The study of the related phenomena has spurred the emergence of a new field, now known as polaritonic chemistry. To fully understand the precise mechanisms underpinning polaritonic chemistry and provide a deeper understanding of the underlying quantum mechanical processes, developing useful theoretical models and advanced computational frameworks to describe and predict the behavior of these hybrid states is crucial. Here we present advanced analytical energy derivative approaches within the framework of the cavity Born-Oppenheimer density functional theory (CBO-DFT) to efficiently calculate the vibro-polaritonic spectra and explore the critical points on the cavity potential energy surface. We not only demonstrate the formulation and implementation of analytical energy gradient and Hessian as well as the infrared (IR) and Raman scattering spectral intensities into the electronic structure software package, but also proposes a classical model that helps us to understand the spectral signatures. As a first application of our developed codes, we study the IR and Raman scattering spectra of acetone in the cavity.

Authors: Maestro Aitor , Ötvös Sándor , Auer Gerald , Kappe Oliver
Published: July 2024

The development of recyclable catalysts has gained more attention in recent years in order to minimize the environmental effect and the overall cost of catalytic processes. Some of the most broadly used chiral organocatalysts are BINOL-derived chiral phosphoric acids, making it necessary to develop efficient recycling strategies. While literature reports require up to 13 synthetic steps to access recyclable chiral phosphoric acids, here we report a general and concise 9-step approach to anthracene decorated heterogeneous chiral phosphoric acids (PS-Anth), which have shown high performance either in batch or continuous flow without observing catalyst degradation.

Published: July 2024

Pollution from dyes is well-known for its harmful effects on human health and the environment. Eliminating pollutants such as dyes is a crucial task that can be achieved through various methods, one of which is adsorption. The synthesis of graphene oxide material is achieved from graphite using the Hummers method. The obtained material was then characterised using XRD and FT-IR techniques and tested as an adsorbent for selective adsorption of anionic dyes. The obtained results indicate that the congo red dye was absorbed the most in the selective dyes process, followed by the methyl orange dye, and finally the direct yellow dye.

Authors: Ahmad Nur , Marlan Abd Rahman , Negara Satria Putra Jaya
Published: July 2024

The removal of hazardous anionic dyes from wastewater is a critical environmental challenge due to their toxic effects and persistence in aquatic systems. This study investigates the adsorption performance of a new composite material, consisting of MgAl layered double hydroxide (LDH) and Lignin (MgAl LDH/Lignin), to remove three different anionic dyes: congo red, direct yellow, and procion red. The composite material was synthesized and thoroughly examined using various techniques, including X-ray diffraction, Fourier transform infrared spectroscopy, Brunauer-Emmett-Teller, and Barrett-Joyner-Halenda. The adsorption isotherm studies indicate that the adsorption of congo red and procion red onto the MgAl LDH/Lignin composite follows the Langmuir isotherm model, suggesting a monolayer adsorption on a uniform surface. On the other hand, the adsorption of direct yellow conforms to the Freundlich isotherm model, indicating the possibility of multiple layers being adsorbed on a surface with varying properties. The maximum adsorption capacities for congo red, direct yellow, and procion red were found to be 75.76 mg/g, 51.55 mg/g, and 74.63 mg/g, respectively. The results of this study demonstrate the promising capabilities of MgAl LDH/Lignin composites as highly efficient adsorbents for the treatment of wastewater contaminated with anionic dyes. This research provides valuable insights into the potential of these composites to address the pressing issue of water pollution in a sustainable manner.

Multi-target Genetic Programming for Nutrient Assessment in Fish
Authors:   , Hussain Amer
Published: July 2024

The Cyber-Marine project aims to maximise the utility of commercial fish by using Artificial Intelligence (AI) supported tools and non-invasive chemical methods to assess their nutrient content. Vibrational Spectroscopy has proven to be a reliable method to determine molecular characteristics of a product. Particularly, it has gained prominence in evaluating the nutrient level of produce through statistical modelling techniques, such as Partial Least Squared regression (PLSR). This thesis investigates the use of Machine Learning (ML) to relate spectral data of fish with their nutrient levels. Within ML algorithms, Genetic Programming for symbolic regression (GPSR) emerges as a notable approach, producing models that exhibit generalisability and interpretability. As an extension of GPSR, multi-tree GP (MTGP), provides a platform that can simultaneously train models for several nutrients or bioactive components. In this thesis, significant enhancements and modifications are made to key aspects of MTGP, including its evolutionary process, by the introduction of new genetic operator, and the evaluation function, through the use of a distance metric. These are designed not only to leverage the relationship between the spectral information and bioactive components, but also to optimise the interplay between different target variables thereby maximising the capabilities of the algorithm.

Punctual categoricity and a jump operation in the primitive recursive degrees
Authors: Kalimullin I. Sh. , Kurmacheva A. A.
Published: July 2024

The paper is devoted to the study of punctual structures such that any isomorphism between any of its punctual copies is primitive recursively reducible to a fixed 0, 1-valued oracle function. To estimate the complexity of such punctual structures and isomorphisms between them we introduce and investigate the weak (0, 1-valued) jump operation. In the paper we establish that there is a rigid punctual structure for which all isomorphisms are low under the weak jump, and at least one of them is not primitive recursive. Also we construct a rigid punctual structure with every isomorphism reducible to the weak jump of the zero function, and with at least one having a high degree.

This contribution targets the solution of fractional differential equations (FDEs) via novel iterative approach and in a new class of nonlinear mappings. Our approach is based on the class of (α, β, γ)-nonexpansive mappings and three-step M-iterative scheme. Under various assumptions, we first carry out some weak and strong convergence results in a setting of a Banach spaces. After this, we carry out an application of one our main result to find approximate solution for a broad class of FDEs. Eventually, we we construct a new example of (α, β, γ)-nonexpansive mappings and show that this new mapping is not continuous on its whole domain and hence it is not nonexpansive. Using this example, we perform a numerical simulation of various iterative scheme including our M-iterative scheme. It has been observed the numerical effectiveness of the M-iterative scheme is high as compared to the other iterative schemes. Accordingly, our main outcome is new/extends some known results of the literature.

Over the last years, application of morphing technologies in aircraft design field have become widespread together with developments in material technologies. In this context, this study discusses the design of an innovative twist-morphing wing on a fixed-wing unmanned aerial vehicle (UAV) aiming for obtaining improvement in stall behavior (i.e. stall propagation) and autonomous flight performance. The twist-morphing wing design was designed to be capable of twisting in terms of wash-out angle between 0-degree to 6-degree. In order to have such a multidisciplinary improvement, simultaneous design approach was integrated and SPSA optimization algorithm was used. The washout angle and longitudinal and lateral PID controller coefficients were optimized to have enhancement in autonomous flight performance defined in rise time, settling time and maximum overshoot, which are related with step responses. In result, longitudinal, lateral and total performances were improved by 33.92%, 33.81% and 65.14%, respectively.

Sharia Compliance in Islamic Financial Institutions is compliance, fulfilment of basic values and absolute prices. As an institution that carries the name sharia, KSPPS is expected to provide a better understanding for the general public directly, because its role is closer to the community. This study aims to determine the extent to which the performance of DPS will affect the course of the development of KSPPS in the village. Qualitative descriptive research method. The data collection techniques used were documentation studies, in-depth interviews, analysis was done by narrating the results of interviews, which were then processed again by the author. The result of this research is that sharia compliance has not been fulfilled in the performance of DPS in KSPPS Padang City. The author found that the appointment of DPS is only seen from the point of view of the community store around KSPPS or the village alone, besides that there is also concurrent work so that there is also no standard procedure from the institution on the performance of the DPS. The selected DPS should have integral scientific qualifications, namely understanding the science of muamalah fiqh, sharia and modern Islamic financial economics. It is not the qualifications of all majors.

Published: July 2024

This research aims to determine the influence between machiavellian personality and whistleblowing intentions on whistleblowing behavior in the form of retweets on reporting news threads on Twitter with whistleblower intentions. This research is a quasi-experiment with 154 research participants who actively use the Twitter application. Participants were asked to give a reaction to a thread. Whistleblower behavior is seen from the behavior of participants who retweet and quote retweet the threads sent by the researcher. The results of this study indicate that machiavellian personality does not directly affect whistleblowing behavior in the form of retweets and quote retweets. However, whistleblowing intention has an influence on whistleblowing behavior in the form of retweets and quote retweets. It is suspected that the types of posts that are not directly related to the interests of people with machiavellian personality make them not show whistleblowing behavior.

Optimization of radiation dose distribution in clinical planning using a Treatment Planning System (TPS) for radiotherapy patients is crucial to achieving a balance between therapeutic effectiveness and patient safety. However, this process is time-consuming and relies heavily on the expertise of medical physicists. In this study, dose prediction using machine learning was performed on the Planning Target Volume (PTV) and Organ at Risk (OAR) for brain cancer cases using the Volumetric Modulated Arc Therapy (VMAT) planning technique. The planning DICOM data were extracted for radiomic and dosiomic values, which were then used as input and output in this study using a random forest algorithm model. Model evaluation results indicated that the random forest model's performance in predicting dose had a Mean Square Error (MSE) value of 0.018. The Homogeneity Index (HI) and Conformity Index (CI) values for the clinical data were 0.136±0.134 and 0.939±0.131 respectively, while the predicted results were 0.136±0.039 and 0.949±0.006, with p-values for PTV and OAR features > 0.05. Thus, it can be concluded that the random forest model is effective in predicting dose for PTV brain cancer and OAR and can function as a reference in the planning process.

Carbon sequestration assessment in Kazakhstan’s forests: analytical review
Authors: Borissova Yu. ,   German Kazakh University
Published: July 2024

Emissions of greenhouse gases in the atmosphere, which are predominantly carbon monoxide and carbon dioxide are led to the process of climate change that takes place on a global scale. This analytical review presents current knowledge and evaluates existing studies on carbon sequestration by forests in the world and in Kazakhstan. Forests play a key role in climate change, absorbing large amounts of carbon dioxide emissions from the atmosphere. They are the most important terrestrial carbon sink. Two key indicators can predict the level of carbon sequestration in forest ecosystems: biomass and productivity. Methods of assessing the sequestration of carbon dioxide by forests include the use of different models, such as inVEST, CO2FIX, and CBM-CFS3, among others. Forests have a three-fold role in climate change. They have been found to accumulate, absorb and allocate carbon dioxide gas. Because carbon sequestration of forest ecosystems in Kazakhstan has been poorly studied, there is a need for further research in this area. The development of afforestation and commercial forestry are the main recommendations for increasing the potential of carbon sequestration by forests. The development of these areas will promote an increase in efficiency and sustainable development of forest resources in the context of climate change adaptation.

Authors: Samorodskaya I.
Published: July 2024

Objective. To assess the changes and variability of regional mortality rates from stroke in the period of 2013 to 2021 and to discuss the probable causes of changes and differences. Material and methods. The authors have used the Russian Federal State Statistics Service (ROSTAT) data obtained upon the request of the National Medical Research Center for Therapy and Preventive Medicine, Ministry of Health of Russia. The standardized mortality rates (SMRs) were calculated using the European Standard and on the ROSTAT Brief Death Nomenclature, that takes into account the following ICD-10 codes: subarachnoid hemorrhage (I60); intracerebral and other non-traumatic intracranial hemorrhages (I61-62); brain infarction (I63); stroke unspecified as hemorrhage or infarction (I64). Results. There was a decrease in the average regional stroke rates from 2013 to 2019 (95.9±30.9 and 68.1±22.2 per 100,000 population, respectively) with stagnation in 2020-2021 (70.8±22.8 and 68.9±21.5 per 100,000, respectively). Only in Moscow, there was an annual consequent reduction in stroke rates; this was noted in 15 regions before 2019; in 7 regions in 2021 the SMRs was higher than in 2013. The most significant changes in SMRs (in 2013 – 17.6±16.3 per 100,000 population, in 2021 – 1.3±2.2 per 100,000 population) were registered for the code I64, with the highest coefficient of variation of regional SMRs (from 92.7 to 161.6% in different years); the share of I64 among the causes of death from all stroke decreased significantly from 2013 to 2021 – 17.1±11.7 and 2.1±3.4%, respectively. Conclusion. Significant variability of regional SMRs from individual types of stroke and their shares in the structure of mortality from all forms of stroke was revealed, which may be associated with both differences in morbidity, organization of medical care, and peculiarities of coding of causes of death. The growth of SMRs in 2020-2021 is possibly associated with the COVID-19 pandemic.
