Data-driven Simulations of Magnetic Field Evolution in Active Region 11429: Magneto-frictional Method Using PENCIL CODE
Authors: Vemareddy P. , Warnecke Jörn , Bourdin Ph. A. 
Published: December 2023

Abstract
Coronal magnetic fields evolve quasi-statically over long timescales and dynamically over short timescales. As of now there exist no regular measurements of coronal magnetic fields, and therefore generating the coronal magnetic field evolution using observations of the magnetic field at the photosphere is a fundamental requirement to understanding the origin of transient phenomena from solar active regions (ARs). Using the magneto-friction (MF) approach, we aim to simulate the coronal field evolution in the solar AR 11429. The MF method is implemented in the open source Pencil Code along with a driver module to drive the initial field with different boundary conditions prescribed from observed vector magnetic fields at the photosphere. In order to work with vector potential and the observations, we prescribe three types of bottom boundary drivers with varying free-magnetic energy. The MF simulation reproduces the magnetic structure, which better matches the sigmoidal morphology exhibited by Atmospheric Imaging Assembly (AIA) images at the pre-eruptive time. We found that the already sheared field further driven by the sheared magnetic field will maintain and further build the highly sheared coronal magnetic configuration, as seen in AR 11429. Data-driven MF simulation is a viable tool to generate the coronal magnetic field evolution, capturing the formation of the twisted flux rope and its eruption.

Published: December 2023

Abstract
In Uzbekistan, livestock, poultry and fisheries are developing in the form of small family farms, and the demand for granulated feed is increasing in them. Since the existing granulation lines are designed for large farms, small farms have to buy granulated feed from abroad. This causes them to spend more on raising livestock, poultry and fish. Based on this, research is being conducted on the development of a small granulation line for small farms. As a result of the research, a small-sized feed mixing device for the granulation line was developed. The working cycle of the device is cyclic, it has working bodies with an auger on the edge and a blade in the middle, and it ensures uniform mixing of the feed at a level of more than 95% with low energy consumption.

Published: December 2023

Abstract
The article is devoted to the synthesis of the mechanism of an elliptical drum of a vertically spindle drum, which increases the completeness of the collection and the quality of the harvested raw cotton. In particular, it developed a methodology for substantiating the profile and dimensions of the guide track, which ensures the movement of the spindles along an elliptical trajectory. At the same time, the profile and dimensions of the guide track are considered as a function of the trajectory and kinematic modes of the spindle. It is shown that the trajectory of movement and kinematic modes of the center of the guide roller can be the basis for choosing the profile and basic geometric dimensions of the guide track. The trajectory of the center of the guide roller at its different positions relative to the center of the spindle, moving along an elliptical trajectory, is determined using the GeoGebra program, which is popular in the mathematical modeling environment, and its kinematic parameters are determined by constructing hodographs of the speed of the center of the guide roller.

Authors: Ponikarova Anna 
Published: December 2023

Abstract
The study identifies the need of modern companies to achieve sustainable development. For these purposes, it is necessary to use an integrated and systematic approach within which it is possible to implement the optimization of processes to ensure environmental safety. To implement these principles it is proposed to use digital technologies that can algorithmize and systematize enterprise processes, highlight the environmental component in them and develop a program for its innovative changes within the framework of sustainable development. The article notes that in the context of the transition to a digital economy, enterprises must most effectively select new technologies to improve environmental safety in conditions of uncertainty. For these purposes, a certain range of digital tools and programs are being considered that allow the most effective implementation of environmental innovations. It is proved that the introduction of digital tools in the process of introducing environmental innovations will allow achieving a qualitative change in the systematic management of environmental safety in conditions of uncertainty and leads to an increase in the pace of sustainable development and the effect of production activities.
Influence of crop rotations and cotton monoculture on cotton field weediness
Authors: Tadjiev M , Tadjiev K M 
Published: December 2023

Abstract
The paper proves that crop rotation and cotton monoculture turned out to be the best agro technical measures in reducing the number of weeds against the control variant which was found by the authors as a result of long-term studies of cotton crop rotations. The results of the studies showed that permanent cotton crop without and with mineral fertilizers in the absence of crop rotation contribute to a significant increase in the number of annual and perennial weeds. Development of crop rotations with strict alternation of cotton with the main predecessors in the cotton complex, as well as appropriate agro-technical measures significantly reduce the weed infestation of cotton field during the entire cotton growing season.

Authors: Kazarina AV , Abramenko IS 
Published: December 2023

Abstract
The ecological flexibility, stability, and adaptability of the “seed weight per plant” trait of soybean raw materialwere assessed in the forest-steppe conditions of the Middle Volga Region. The most valuable varieties for use in the breeding process for this trait were selected. The experimental work was carried out in 2019—2021. In total, 14 soybean varieties of various ecological and geographical origins were assessed. The regionalized agricultural variety of local selection, Yuzhanka, was set as the standard. The soil at the experimental plot was represented by typical medium-humus, medium-thick, medium-clay chernozem. The humus content was 5.8—6.9%, the content of mobile forms of phosphorus, 133.6—156.5 mg/kg, exchangeable potassium, 154.0—180.0 mg/kg. In 2019—2021, in the forest-steppe of the Middle Volga Region, average individual productivity of soybean plants was 7.47—12.17 g. The highest individual seed productivity was registered in the varieties 680-11 (Ukraine), 422 (Kazakhstan), OX 299 (Canada), L-60/2018 and Nika (Russia), exceeding the standard by 4.97—5.43 g. The lowest total rank was found for varieties 422 (Kazakhstan) – 23, Nika (Russia) – 28, Gessener (Yugoslavia) – 28, L-59/2018 (Russia) – 29 , OX 299 (Canada) – 31, and 680-11 (Ukraine) – 34, while the standard variety refers to 72. These varieties are promising raw material for developing soybean varieties with high productivity potential due to the effective use of the soil and climatic conditions of the region and resistance to dominant environmental stress factors.

Published: December 2023

Abstract
After determining the physical-mechanical properties of industrial grain of the corn, we decided to compare the results of experiment with properties of seed-corn. According to some agronomic researchers’ observation, there is special determination method to harvest corn-crop for producing seed-corn. Therefore, because of the observations and analysis, it is an actual theme to do research on creating new innovative corn-seed preparing technologies and grader machines based on smart technological methods. Otherwise, it is difficult to grade precise properties of corn-seed. Therefore, we created new innovative corn-seed grader machine, developed constructive scheme and its 3D model of the smart corn-seed grader machine, and based its positions. It has been known that, the width of the receiving section of the machine should be Bb
=0.157 m and Bb
=0.314 m when the amount of pod-corn transferred to the device in a unit time is between 1 kg/s and 2 kg/s depending on their average length, diameter and mass.

Abstract
Lake Sudochye is the only large lake on the left bank of the Amudarya River delta. The current nature of changes in the environmental situation, conservation of biodiversity and sustainable development in this region largely depends on the life activity of the Sudochinsko - Mashankul - Karazhar lake system. Sudoche is relevant not only from the point of view of preserving a large unique natural site, but also plays a huge role in the development of the economic potential of the Muynak and Kungrad regions of the Republic of Karakalpakstan, and most importantly, the lakes. Sudoche is the main link of the world migratory route of migratory birds, and is included in the Ramsar Convention list. In addition, Lake Sudochye is a natural reserve of unique flora and fauna that has no ecological analogues.

Published: December 2023

Abstract
Forest management improvement is an important task, especially in the context of the development of forest areas with a depleted resource base. When carrying out non-clear cuttings, the main operation that has the greatest negative impact on the trees left for growing is skidding, during which trees located along the portage and, especially, at the turn, can receive damage, consisting in damage to the root system and trunk bark. It is possible to prevent damage to the trunks of trees left for growing by using fencing devices, which can be made from logging resi-dues located in the cutting area, or from slabs obtained by sawing logs. The use of a protective device does not require large expenses due to the use of substandard wood; after skidding the devices can be easily removed and put on other trees.
Study of the properties of asphalt concrete based on solid waste from cement production
Authors: Ibrokhimov G B , Shukurov J L , Khasanov Ch A , Omondavlatov S S , Tovoshareva I E 
Published: December 2023

Abstract
It is known that in the production of cement, clinker is treated at a temperature of 1350-1400 C°. During this process, slag is formed in the furnace. In addition, dispersed cement dust accumulates in dust retention filters. One of the ways to effectively use them is to use them as fillers or modifiers in the production of various composite materials. After special processing, the possibility of using these wastes as a modifying filler in increasing the strength of asphalt concrete compositions was studied.

Testing of a temporary railway bridge and analysis of the results
Authors: Topurova Ivanka 
Published: December 2023

Abstract
The main purpose of bridge testing, an obligatory step before putting a railway bridge in operation, is to ensure that the used theoretical model is in accordance with the actual behaviour of the structure. Furthermore, bridge testing can point to some problems or inaccuracies due to construction.
Even though temporary bridges typically have shorter spans, they have relatively low self-weight and the main strains are caused by live loads. Therefore, bridge testing is particularly important to ensure the proper performance of such structures.
This paper outlines some major steps of the testing process and draws conclusions based on a temporary railway bridge located along the Kalotina Highway in Bulgaria.
Structures for permanent stabilization of the sea coast
Authors: Zhechev Nikolay 
Published: December 2023

Abstract
The coastal protection of the country, built in the early 1970s, has been devoid of even preventive measures such as depositing crushed rock along the coastal shoreline for several decades. Instead of prevention, an entirely ineffective defensive concept has been implemented, with concrete protective barriers accumulating along the shores and temporary breakwaters and groynes being created using additional concrete blocks. These measures, which essentially destroy the coast, are complemented by periodic sand embankments during winter, excavated from the coastal strip and piled in front of iconic coastal establishments. All these activities lead to terrain destabilization and erosion of the country’s coastline and sandy shore.
The planned embankment along the Black Sea coast is not a solution to the problem either. Firstly, this dam is insufficient for regions like Balchik to create the necessary counterbalance to ensure the stability of the landslide slope. Secondly, the practice where such structures have been built shows that landslides continue due to ongoing coastal erosion caused by the energy of waves passing through the dam. Thirdly, this type of dam makes the beaches difficult to access and unattractive due to the lack of sand.
After analyzing the current state and the reasons for ongoing processes of slope destabilization and the loss of sandy beaches along the Black Sea coast, measures for sustainable coastal protection are proposed. Conclusions and recommendations for practice have been drawn.
On the need for connectivity and a new strategic approach to building road infrastructure in the Balkans
Authors: Tsonkov Nikolay , Petrov Kamen 
Published: December 2023

Abstract
The Bulgarian state is characterized by its geostrategic location. However, the country has not taken advantage of its natural localization. The main reasons for this are the lack of strategic thinking and implementation of a targeted and active transport policy within Bulgaria and the Balkans. This policy includes the planning and realization of projects in the field of strategic infrastructure. The policy is adopted in the context of the trans-European transport corridors. This will create conditions for connectivity between Bulgarian regions and conditions for stimulating cross-border cooperation. In this direction, the authors analyze the transport sector and infrastructure in Bulgaria to highlight the important areas where the Bulgarian state needs to take urgent action. In this regard, it is necessary to formulate the major priorities that will take place in a new strategy for the transport sector. The strategy is related to the reconducting of political activities, measures, and acceleration of the investments in Bulgaria’s strategic road infrastructure.

Published: December 2023

Abstract

Summary
Barcode-based sequence census assays utilize custom or random oligonucloetide sequences to label various biological features, such as cell-surface proteins or CRISPR perturbations. These assays all rely on barcode quantification, a task that is complicated by barcode design and technical noise. We introduce a modular approach to quantifying barcodes that achieves speed and memory improvements over existing tools. We also introduce a set of quality control metrics, and accompanying tool, for validating barcode designs.

Authors: Nouri Nima , Kurlovs Andre H , Gaglia Giorgio , de Rinaldis Emanuele , Savova Virginia 
Published: December 2023

Abstract

Summary
Single-cell RNA sequencing (scRNA-seq) has revolutionized the study of gene expression at the individual cell level, unraveling unprecedented insights into cellular heterogeneity. However, the analysis of scRNA-seq data remains a challenging and time-consuming task, often demanding advanced computational expertise, rendering it impractical for high-volume environments and applications. We present CellBridge, an automated workflow designed to simplify the standard procedures entailed in scRNA-seq data analysis, eliminating the need for specialized computational expertise. CellBridge utilizes state-of-the-art computational methods, integrating a range of advanced functionalities, covering the entire process from raw unaligned sequencing reads to cell type annotation. Hence, CellBridge accelerates the pace of discovery by seamlessly enabling insights into vast volumes of scRNA-seq data, without compromising workflow control and reproducibility.

ELISL: early–late integrated synthetic lethality prediction in cancer
Authors: Tepeli Yasin I , Seale Colm , Gonçalves Joana P 
Published: December 2023

Abstract

Motivation
Anti-cancer therapies based on synthetic lethality (SL) exploit tumour vulnerabilities for treatment with reduced side effects, by targeting a gene that is jointly essential with another whose function is lost. Computational prediction is key to expedite SL screening, yet existing methods are vulnerable to prevalent selection bias in SL data and reliant on cancer or tissue type-specific omics, which can be scarce. Notably, sequence similarity remains underexplored as a proxy for related gene function and joint essentiality.

Results
We propose ELISL, Early–Late Integrated SL prediction with forest ensembles, using context-free protein sequence embeddings and context-specific omics from cell lines and tissue. Across eight cancer types, ELISL showed superior robustness to selection bias and recovery of known SL genes, as well as promising cross-cancer predictions. Co-occurring mutations in a BRCA gene and ELISL-predicted pairs from the HH, FGF, WNT, or NEIL gene families were associated with longer patient survival times, revealing therapeutic potential.
