Recultivation of fallow lands with soil moisture regulation

The technologies for implementing the tasks of involving fallow lands in agricultural turnover and increasing the fertility of agricultural lands in the long-term period of economic activity are highlighted. Insufficient informativeness of the use of yield maps to assess the fertility of fields has been revealed. It is proposed to use field relief maps to establish the dynamics of violation of the water-air regime of the soil. It is proved that in the process of involving fallow lands into circulation, it is necessary to introduce a technological operation of microtopographic analysis of the degree of soil moisture. An algorithm for enabling the operation of levelling of field surface (removal of relief) using modern positioning systems has been developed. It was revealed that the levelling of the field with a laser level allowed to reduce yield fluctuations by 20% within the crop acres of the field and increase yield by 25-30%. Disadvantages of positioning accuracy with the use of laser and satellite positioning have been established. It is proposed to transfer digital information transmission modules to network clusters with the choice of the best digital data transmission channel by including an uninterrupted positioning module with digital data transmission over a 434 MHz and 864 MHz radio channel with a range of up to 600 meters to other modules for providing digital positioning information to the machine. The plan of implementation of the concept of digital field formation on the basis of the field experimental station of the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy is presented, with the aim of creating a frontier for the sustainable development of closed-life cycle technologies through the introduction of innovations using multiplicative interaction of mechatronic systems and telematics for agricultural technology.

Development of a β-Globin Gene Replacement Strategy As a β-Thalassemia Therapy

Background: β-thalassemia is a genetic disorder with high unmet need worldwide. Over 300 genetic mutations that result in the reduction, or loss, of β-globin (HBB) expression have been characterized to date. Patients with thalassemic mutations in both HBB alleles often experience severe anemia resulting from ineffective erythropoiesis due to the loss of adult hemoglobin (HbA) tetramers (α2β2) and imbalanced excess of α-globin chains. One challenge is creating a genome-editing strategy that replaces the diversity of disease-causing mutations in the HBB gene while restoring physiological HbA expression. Therefore, a gene-editing platform using homology-directed repair (HDR) that could replace the entire HBB gene in situ and under the control of normal regulatory elements would be an ideal strategy. Methods: CD34+ hematopoietic stem and progenitor cells (HSPCs) were edited using high-fidelity Cas9, HBB guide RNA, and different AAV6 DNA donor templates and then differentiated into red blood cells in vitro. We evaluated HBB expression in 39 AAV6 donors engineered with heterologous introns and different polyadenylation signals first using a flow cytometry screening assay and later HPLC. Candidates that met or exceeded wild-type HBB expression were moved forward for further comparison. Next, we edited HSPCs with the 8 highest expressing AAV6 donors, performed in vitro differentiation, and evaluated HDR frequencies by droplet digital polymerase chain reaction (ddPCR) and HbA formation by HPLC. The candidate that demonstrated the highest conversion of donor knock-in to HbA was further engineered to boost expression and reduce construct size. Two final candidates were moved forward to further characterize their ability to rescue loss of HbA in CD34+ HSPCs isolated from patients with sickle cell disease (SCD) at the protein and RNA level. Additionally, we performed DNA analysis on the gene-edited cells using ddPCR and a targeted PCR-free long-range sequencing approach. Results: Adding heterologous introns to the HBB coding sequence significantly increased HBB expression relative to the no-intron construct containing only coding DNA. The results from our flow cytometry screen and HPLC analysis were positively correlated, and the top DNA donors with heterologous introns resulted in physiologic HbA expression. Using this gene-replacement strategy, we achieved HDR frequencies of up to 40% in CD34+ HSPCs. Further optimization resulted in a smaller DNA template, maintenance of HbA conversion rates, and a lower rate of unintended recombinations. Finally, using HSPCs from patients with SCD as a therapeutically relevant model, we found, by HPLC and RNA sequencing, the optimized DNA donor can successfully replace the entire nonfunctional HBB gene, thereby restoring physiologic HbA expression. Future experiments are investigating in vitro gene correction in cells isolated from patients with β-thalassemia and additional studies evaluating in vivo stem cell repopulation capacity of gene-edited HSPCs. Conclusion: We developed an HBB AAV6 donor engineered with heterologous introns that demonstrates efficient HBB gene replacement and HbA rescue in the erythroid progeny of CD34+ HSPCs isolated from patients with SCD, offering a potential differentiated approach for treating β-thalassemia.

Tissue-specific requirement of sodium channel and clathrin linker 1 (Sclt1) for ciliogenesis during limb development.

Primary cilia have essential roles as signaling centers during development and adult homeostasis. Disruption of ciliary structure or function causes congenital human disorders called ciliopathies. Centriolar distal appendage (DAP) proteins are important for anchoring cilia to the membrane. However, the exact functions of DAP during in vivo ciliogenesis and animal development remain poorly understood. Here, we showed that the DAP component sodium channel and clathrin linker 1 (Sclt1) mutant mice had abnormal craniofacial and limb development with postnatal lethality. In mutant embryos, most of the affected tissues had defects in DAP recruitment to the basal body and docking to the membrane that resulted in reduced ciliogenesis and disrupted hedgehog (Hh) signaling in limb bud mesenchymal cells. However, limb digit formation and ciliogenesis in Sclt1 mutant mice were differentially affected between the fore- and hindlimb buds. The forelimbs developed normally in Sclt1 mutants, but the hindlimbs had preaxial polydactyly. Heterozygous loss of Cep83, another core DAP component, in Sclt1 mutant mice, caused forelimb and hindlimb polydactyly. These findings revealed the tissue-specific differential requirement of DAPs. Taken together, these results indicated that during limb development the ciliary base components, DAPs, play an essential role in ciliogenesis and Hh signaling in vivo in a position-dependent manner.

A Fast Digital Phase Frequency Detector with Preset Word Frequency Searching in ADPLL for a UHF RFID Reader

An All-Digital Phase-Locked Loop (ADPLL) is an architecture that is widely employed in the communication system due to the advancement of the Complementary Metal-Oxide-Semiconductor (CMOS) technology process. A 2.4GHz Radio Frequency Identification (RFID) system needs a frequency synthesizer in the local oscillator architecture of the transceiver to generate a stable frequency tuning range Therefore, in this paper, a Digital Phase-Frequency Detector (DPFD) is designed to achieve the phase and frequency acquisition in the ADPLL system. The proposed DPFD is divided into two main parts, the first is the Phase Detector (PD) and the second is the Frequency Detector (FD). The PD has managed to detect the presence of the phase difference by recognizing two different input signals. The FD, on the other hand, is capable to detect the higher frequency by identifying the output signals from the PD in digital formation. In addition, a control unit module is developed to control and adjust the Preset Word (PW) for the system by using a binary search scheme. Comparison results show that the final value of the PW from the simulation is the same as from the manual calculation (theoretical values). The digital PFD and the PW control modules are designed and simulated by using Verilog HDL code. These two designed modules will be integrated into the targeted ADPLL to achieve fast locking performance and ultra-low power for Ultra-High Frequency (UHF) RFID applications.

Educational digital transformation and digital Competences: legal aspects

In the article the author considers the legal aspects of the digital transformation process in the field of education and the digital competences formation to ensure the processes of global digitalization of the economy. For the study purposes the concept of “educational digital transformation” is formulated as the transformation of the mechanisms of human formation as a person, their talents, intellectual, creative and physical abilities, and values through the use of digital technologies in the formal and informal educational process. Such digital transformation occurs at two levels. At the educational and methodological support level by updating lectures, practical tasks with interactive teaching methods, participants communication in educational process. The second level is the organization of educational institutions as research platforms. The genesis of the concepts “information literacy”, “media literacy”, “digital literacy” and “metaliteracy” are studied. Considering the concept of metaliteracy the category “information technology competences” is proposed. Information competences are based on information processing skills at all stages of the information process and technological competence is related to the formation of skills for working with hardware and software devices and depends on the professional field of activity. By means of proposed classification of “information-technological competences” the Framework of digital competences and two standards of higher education (specialty 081 “Law” and 015 “Professional education” (pedagogy) are analyzed. It is established that in the standards of education, in addition to information-technological competences, there is an additional group of professional information competences. They are related to the high abstract cognition ability in professional activities (the ability to learn, apply knowledge in practice, analyze retrospectives, carry out comparative analysis, determine appropriate and acceptable facts, analyze problems, the ability for logical, critical and systematic analysis). The implementation of these standards and the development of information technology competences can solve some tasks of the educational digital transformation. Firstly, the standard enshrines the legal regulation of the development of information and technological competences. Secondly, the requirements for educating lawyers and teachers, who will understand the socio-economic processes of digital transformation, and will be able to make a major contribution to the digital transformation of education system and other areas of the digital economy ensuring its legal regulation, are formulated.

The article highlights the concept of emergency digitalization of education as a response to the realities of today’s educational processes, determined by the restrictions of physical contacts due to the Coronavirus pandemic, and further by the lack of possibility for conducting educational process in classrooms due to the war in Ukraine. Digital competence is seen in the article as one of the key competences of educators who currently face the challenges of emergency digitalization of education. While highlighting the elements and structure of digital competence of educators, the article is grounded on the provisions of the European framework of digital competence of educators as a model for defining the essence of digital competence. The article outlines six main areas of digital competence, which focus on various aspects of professional activities of educators, and briefly describes each of them: professional engagement, digital resources; organization of training; assessment; expansion of educational opportunities; facilitating learners’digital competence. The main tasks placed before educators in the context of the digital competence formation have been identified in the article. They include, in particular, the identification and selection of appropriate digital resources, taking into account the context and objectives of learning; critical assessment of the reliability of digital products and resources; restrictions on the use or reuse of digital resources (copyright, file type, technical requirements, legal provisions, availability); the ability to assess the benefits of digital resources in addressing a specific learning goal, the level of digital competence of a particular learner, as well as the correlation of the pedagogical approach with digital resources; ability to select and combine existing digital resources or their parts, to create new digital educational resources and products; collaboration in the field of digital educational resources.

Digital Twin Formation Method for Distributed Generation Plants of Cyber–Physical Power Supply Systems

The purpose of the study presented in the article was to develop a method for the formation of digital twins for distributed generation plants operating as part of cyber–physical power supply systems. A method of forming a digital twin for a system for automatic regulation of the voltage and rotor speed of a synchronous generator is considered. The structure of a digital twin is presented in the form of a multiply connected model using experimental data. The possibility of using a fuzzy inference system, artificial neural networks, and a genetic algorithm for solving the problem is shown. As a result of the research, neuro-fuzzy models of the elements of the distributed generation plant were obtained, which are an integral part of the digital twin. Based on the simulation results, the following conclusions were drawn: the proposed method for constructing an optimized fuzzy model gives acceptable results when compared with experimental data and shows practical applicability in constructing a digital twin. In the future, in order to simplify the model, it is necessary to solve the problem of optimizing the number of rules in the fuzzy inference system. It is also advisable to direct further research to the formation of a complete hierarchical fuzzy system that connects all elements of the digital twin.

Personality and Sexual Perceptions of Penises: Digital Impression Formation.

Dating app users are likely to experience a high frequency of viewing the sexually explicit material of potential partners prior to a physical meeting. The present study aimed to investigate what information is inferred from a picture of a penis at zero-acquaintance. Past research in impression formation at zero-acquaintance has demonstrated a stability with regard to personality and trait perceptions of faces. Utilizing 106 participants, our study extends this paradigm by testing the hypothesis that penis prototypicality would be associated with attractiveness, as well as explore the personality and sexual perceptions of penises along the dimensions of girth, length, and amount of pubic hair. The hypotheses were confirmed and the analysis of penis dimensions revealed strong results. Penises which were wider, longer, and moderately hairy were perceived more positively in terms of personality and sexual appeal. Shorter and narrower penises were perceived as more neurotic. The results demonstrate the function of impression formation within the digital sexual landscape with regard to sexually explicit material.

Digitalization of intersubjective interactions in product chains

The efficiency of value added chains (product chains) largely depends on the interaction quality between subjects, located both in different links of these chains, and inside these links. The business communication tools and technologies evolution ensures the continuous development of information processes’s organization forms and methods occurring within product chains and the entire subjects interaction system integrated into them. The achieved level of information infrastructure’s development and information and communication technologies makes it possible to improve fundamentally the quality of intersubjective interactions between the participants associations’s integrated through the product chain digital ecosystem formation and the inclusion in it of all interacting subjects. Digital systems as a form of subjects informational coexistence and interaction integrated into the product chains of the agro-food complex require justification of their functionality, formation principles and provisions reflecting the industry specifics of the intersubjective interactions organization.

Identification of structural control factors of primary gold ore occurrences by method of unmanned aeromagnetic survey by the example of the Neryungrisky district of Yakutia

The long-term development of the geophysical industry, in which the methods of magnetometry are in maximum demand, as the simplest in instrumental and methodological execution, has determined the development of remote measurement methods implemented both from space and airborne carriers. The necessity to use the latter as an obligatory component of field surveys, providing coverage of significant areas, determines the need for using the unmanned low-tonnage carriers. Their use is implemented to search for predictive elements of structural (spatial, genetic) control of endogenous gold ore occurrences that allow predictive constructions, i.e., solving the problem of increasing gold reserves, which is being performed within the framework of federal programs. The purpose of the survey is to develop a system of instrumental and subsequent interpretation approaches in the organization of unmanned magnetometer survey, implemented for structural and geological mapping by the example of the Neryungrinsky district of Yakutia. Within the framework of the digital model formation of the relief and the anomalous magnetic field, a survey method using an unmanned aircraft, its technical characteristics are considered; the analysis and the author's modification of the office analysis of magnetometry data are performed. Based on the obtained materials, a physical and geological model of the investigated area was created, which is presented in the form of a geological and structural cut, accompanied by the physical characteristics of the structural and material complexes. The refinement of the physical and geological model was implemented by a joint morphostructural analysis of the remote base and the anomalous magnetic field using the results of quantative interpretation of the anomalous magnetic field. The result of the study is presented by an updated geological basis with the allocation of promising ore sites for their detailing as part of the planned large-scale geological and geophysical surveys. The scientific novelty of the work consists in the synthesis of the tried and tested methods of unmanned aeromagnetometric measurements and geostructural reconstructions, which allow the processing of both potential and non-potential geofields.
