Published: April 2023

The article presents an analysis of the potato breeding problems in Russia which are associated with the low phytosanitary state of potato seed material infected with viral and bacterial diseases, as a result, it is necessary to carry out its improvement and the use of Russian varieties. Experiments were conducted in the laboratory of plant microclonal propagation according to the methodological recommendations for improvement and accelerated propagation of seed potatoes. The results of research on refining the technology of seed potato improvement by adding the Oxolin antiviral drug to the standard nutrient medium MS; its optimal concentrations for obtaining the largest number of uninfected plants of the studied varieties were identified. For potato varieties Liga, Hussar, and Real, the optimal concentration was 20 mg/l of Oxolin, while in the varieties Aurora, Real, and Sirenevy tuman, the concentration was 30 mg/l. Therefore, it is necessary to search for antiviral drugs with an alternative mechanism of action which remains very relevant and practically significant. The research results obtained in this work can be applied both to optimize the cultivation regime of potato microclones in vitro and to enhance the productive process of the uninfected microplants.
Epizootological data of cattle infection caused by bacillus cereus on a dairy farm of the Kemerovo region
Authors: Metleva Anastasia , Smolovskaya Oksana
Published: April 2023

Diseases caused by Bacillus cereus of non-food origin are becoming relevant. This article describes a case of an epizootic situation associated with the spread of B. cereus through cattle feed and its ubiquitous distribution to all environmental objects and animal biotopes on the farm. B. cereus can cause not only food poisoning but also a generalized form of the infectious process, characterized by severe intestinal stagnation with a thickened and edematous wall, hemorrhages on the mucosal surface, catarrhal enteritis, systemic lymphadenopathy, degeneration of muscle fibers, interstitial pneumonia with pulmonary edema and pericardial effusion, meningeal and splenic hyperemia, glomerulonephritis and renal liver failure. Bacillus cereus was the predominant microorganism in quantitative terms with the specified pathoanatomical picture. Microorganisms of the Enterococcuscea, Staphylococcuscea families were found together with B. cereus. B. cereus was found in biological material (cervical mucus, nasal discharge) from live animals and in environmental objects. The removal of contaminated feed from the diet of animals led to a decrease in the death of livestock. It was concluded based on this that the main factor in the transmission of the pathogen was the food supply.

Authors: Pirogov Sergey , Cherentsov Dmitry , Ustinov Nikolai , Smolin Nikolai
Published: April 2023

The designs of the working bodies of tillage and sowing machines are subject to requirements to ensure optimal agrotechnical requirements and minimize energy costs. This can be achieved by creating machines with controlled working bodies that are able to accurately comply with agrotechnical requirements and respond in a timely manner to changing external conditions. Known are designs of the working bodies of tillage machines, in which a flexible tubular element (manometric tubular spring) is used as a stand.

When applying variable pressure to the cavity of the tubular element, its end performs a reciprocating motion, which improves the quality of tillage. The paper presents the results of a study of the stress-strain state of the tubular element of the coulter using the ANSYS software package. The authors built a grid model of a tubular element, determined the horizontal component of the force of the soil impact on the coulter, at which stability loss is observed, and studied the influence of the geometric characteristics of the tubular element—the shape of the section, the opening angle, and the bending radius—on the critical force value. Tubular elements with a section variable in length were also investigated and their effectiveness was shown.

Published: April 2023

This article analyzes data from a study of 72 dogs aged from 8 months to 11 years. A method that helps predict the possible development of complications in animals with obstetric-gynecological and cryptogenic sepsis, as well as purulent wounds and abscesses, was tested on a dog model. Evaluation criteria on PIRO and SAPS scale in the propaedeutics of sepsis in dogs have been formed. A clinical version of the model has been developed to divide patients with sepsis into groups based on their condition. The system is based on the assessment of criteria of sepsis development, based on a set of clinical and laboratory signs that determine risk factors and prognosis of the course of the disease. The prognostic role of the determination of cationic neutrophil proteins in the clinical manifestation of purulent inflammation in dogs was also noted.

Published: April 2023

This research summarizes practical experience on possible ways of restoring and developing seed production of heritage selection tomato varieties in the conditions of southern Kyrgyzstan. At the moment, providing farmers, especially in remote areas, with high-quality and selected seeds of local tomato varieties is difficult. In order to meet the needs of farmers in seeds, measures were taken to organize a seed plot, undergo special training on the technology of tomato production for seeds and create a “community seed bank”. The research material was the local selection variety Bishkek and the heritage released tomato variety Volgogradsky 5/95. The research results have shown that the most acceptable way for farmers to preserve, restore and distribute the heritage selection tomato varieties of Bishkek and Volgogradsky 5/95 was to create a seed exchange network in local communities. During the implementation of the project, joint research work was performed with farmers to assess the yield, seed productivity, selection of fruits for seeds of the studied tomato varieties. Due to the efforts of farmers, endangered tomato seeds have become available through the “community seed bank” for rural residents in remote areas of Batken region.

Published: April 2023

The sustainable development of agriculture is closely related to the quantity and quality of the resource potential and the conditions for reproduction. The paper analyzes the totality, quantitative set and qualitative parameters of labor, land and material and technical resources in the Kyrgyz Republic. The proportions of the reproduction of the resource potential in rural areas depend on the financial condition of an economic entity, the strategy and tactics of its development, the market conditions, and the stage of the economic cycle. There are some problems in realizing the resource potential of the sustainable development of the Kyrgyz Republic, including the lack of a developed innovation market infrastructure for agricultural producers. The uneven development of various components of the resource potential in agriculture is an inevitable factor that determines the specifics of its reproduction. Therefore, the efficiency of the resource potential should be enhanced through the formation of sufficient governmental support aimed at the innovative development of manufacturing, making of environmentally friendly agricultural products and introduction of advanced technologies that will ensure the competitiveness of agricultural enterprises in the context of the need for sustainable development.

Authors: Gallyamova Rida , Dokichev Vladimir , Musin Fanil
Published: April 2023

The paper describes the modification conducted for the PAN carbon fiber surfaces in the solutions of nitric and sulphuric acids. The authors studied the impact of modification parameters such as temperature, acid concentration, time and ratio of the nitrosulphuric acid on the occurrence of reactive groups on the fiber surface. The authors revealed the presence of carboxylic and ketone reactive groups in the range of 1663-1798 and 1568 cm-1 in the IR spectra of carbon fibers. The use of the nitrosulphuric acid did not identify sulfur-containing functional groups on the carbon fiber IR spectra. Preliminary acid treatment of the carbon fiber surface led to the formation of uniform continuous coating of a SiO2 barrier being 127 ± 30 μm by a sol-gel method.

Authors: Kontopodis Nikolaos , Lasithiotakis Konstantinos , Tzartzalou Ifigeneia , Kasiolas Ioannis , Kafetzakis Alexandros , Chrysos Emmanuel , Ioannou Christos V.
Published: April 2023

Background Abdominal compartment syndrome (ACS) often complicates ruptured abdominal aortic aneurysm (rAAA) repair. We report results with routine skin-only abdominal wound closure after rAAA surgical repair.

Methods This was a single-center retrospective study including consecutive patients undergoing rAAA surgical repair for the duration of 7 years. Skin-only closure was routinely performed, and if possible, secondary abdominal closure was performed during the same admission. Demographic information, preoperative hemodynamic condition, and perioperative information (ACS, mortality, rate of abdominal closure, and postoperative outcomes) were collected.

Results During the study period, 93 rAAAs were recorded. Ten patients were too frail to undergo repair or refused treatment. Eighty-three patients underwent immediate surgical repair. The mean age was 72.4 ± 10.5 years, and the vast majority were male (82:1). Preoperative systolic blood pressure <90 mm Hg was recorded in 31 patients. Intraoperative mortality was recorded in nine cases. Overall in-hospital mortality was 34.9% (29/83). Primary fascial closure was performed in five patients, while skin-only closure was performed in 69. ACS was recorded in two cases in whom skin sutures were removed and negative pressure wound treatment was applied. Secondary fascial closure was feasible in 30 patients during the same admission. Among 37 patients not undergoing fascial closure, 18 died and 19 survived and were discharged with a planned ventral hernia repair. Median length of intensive care unit and hospital stay were 5 (1–24) and 13 (8–35) days, respectively. After a mean follow-up of 21 months, telephone contact was possible with 14/19 patients who left the hospital with an abdominal hernia. Three reported hernia-related complications mandating surgical repair, while in 11, this was well tolerated.

Conclusion Routine skin-only closure during rAAA surgical repair results in low rates of ACS at the expense of a high rate of patients being discharged with a planned ventral hernia which, however, seems to be well tolerated by the majority of patients.

Published: April 2023

Background In September 2021, a military camp in the United States was identified for an initial relocation of over 6,600 Afghanistan refugees. This case report describes a novel use of existing health information exchange to expedite and provide health care for a large refugee population throughout the state during the duration of their entry into the United States.

Methods Medical teams of the health systems and military camp partnered to provide a scalable, reliable mechanism for clinical data exchange leveraging an existing regional health information exchange. Exchanges were evaluated for clinical type, originating source, and closed loop communication with the refugee camp and personnel military camp.

Results Approximately 50% of the camp residents were under the age of 18 years. Over 20 weeks, approximately 4.51% of the refugee camp residents were cared for in participating health systems. A total of 2,699 clinical data messages were exchanged, 62% of which were clinical documents.

Conclusion All health systems participating in care were offered support to utilize the tool and process set up using the regional health information exchange. The process and guiding principles may be applied to other refugee health care efforts to provide efficient, scalable, and reliable means of clinical data exchange to health care providers in similar situations.
Primary Aldosteronism and Drug Resistant Hypertension: A
“Chicken-Egg” Story
Authors: Lenzini L , Pintus G , Rossitto G , Seccia T M , Rossi G P
Published: April 2023

Drug-resistant arterial hypertension (RH) is a major risk factor for
cardiovascular disease, often due to overlooked underlying causes.
Identification of such causes poses significant clinical challenges. In this
setting, primary aldosteronism (PA) is a frequent cause of RH and its prevalence
in RH patients is likely higher than 20%.

The pathophysiological link between PA and the development and maintenance of RH
involves target organ damage and the cellular and extracellular effects of
aldosterone excess that promote pro-inflammatory and pro-fibrotic changes in the
kidney and vasculature.

The feasibility of adrenal vein sampling in PA patients with RH, and the clinical
benefit achieved by adrenalectomy, further emphasize the need to implement
systematic screening for this common form of secondary hypertension in the
management of a high-risk population as RH patients.

We herein review the current knowledge of the factors that contribute to the RH
phenotype with a focus on PA and discuss the issues regarding the screening for
PA in this setting and the therapeutic approaches (surgical and medical) aimed
at resolving RH caused by PA.
Hybrid Palatoplasty: A Simplified DOZ (Double Opposing Z Plasty) with Palatal Myoplasty for Primary Palate Repair
Authors: Damalachervu Mukunda Reddy , Yellinedi Rajesh , Nuvvula Rambabu , A. Dharanipriya
Published: April 2023

Introduction Surgical techniques for soft palate repair aiming for zero velopharyngeal insufficiency (VPI) are still not achieved. Straight line closure of the soft palate by various techniques of intravelar veloplasty (IVVP) leads to higher incidence of VPI due to scar contracture. Furlow's Z plasty has long, narrow, thin mucosal flaps and mucomuscular flaps with malaligned muscle closure. We present a technique of “hybrid palatoplasty” which borrows from and adds to the existing methods, is robust, is easy to replicate, and results in normal speech consistently.

Aim (1) To design a technique of “hybrid palatoplasty”—combining double opposing Z (DOZ) plasty and IVVP, which is applicable to all types of cleft palate. (2) To evaluate the results of cleft palate children operated using the technique of “hybrid palatoplasty” from 2014 to 2015 in terms of surgical complications (fistulae and dehiscence) and incidence of VPI.

Methods Our procedure combines aspects of both DOZ and IVVP. It is simplified with design of smaller Z plasties. On one side, from the oral Z plasty muscle is dissected off and sutured to the nasal mucomuscular flap of the opposite side to complete the palatal sling. Oral Z plasty is purely mucosal and reverse of the nasal side. A total of 123 cases, operated below 5 years of age were followed up. Speech was assessed by direct evaluation and tele-evaluation.

Results A total of 123 cases, below 5 years of age, were operated between 2014 and 2016 with at least 5 years of follow-up. Note that 120 had normal speech, and 3 had VPI of which 2 were subsequently corrected and went on to develop normal speech.

Conclusion This novel “hybrid palatoplasty” is a simple technique with good speech outcome as it combines the principles of Z plasty and direct muscle repair with palatal sling formation.
SARS-CoV-2-Related Pediatric Encephalopathy with Biphasic Convulsions and Cortical Blindness: A Case Report
Authors: Shiraishi Yuriko , Tomari Kouki , Matsuoka Tsuyoshi , Numazawa Masaya , Matsuoka Takashi
Published: April 2023

Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) is an encephalopathy syndrome that develops during the febrile phase of infection and is characterized by biphasic seizures and bright tree appearance (BTA) on imaging. In this study, we examined a 1-year-old child who was diagnosed with AESD caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. He had a fever for 2 days and was diagnosed with coronavirus disease 2019 on the day of consultation based on a positive antigen test for SARS-CoV-2. The seizures had stopped on arrival to hospital; however, symptoms of encephalopathy persisted. Despite being treated for acute encephalopathy with steroid pulse therapy, vitamins, and remdesivir, he had poor expressive language, and electroencephalography showed generalized slow waves. A repeat head magnetic resonance imaging showed BTA in the parietal and occipital lobes, and seizures recurred during hospital stay. He was also found to have cortical blindness. At the 4-month follow-up, the vision gradually improved and the hand movements recovered. SARS-CoV-2 infection can cause febrile convulsions, which can lead to the development of AESD. Furthermore, a subtype of AESD has occipital lobe predominant lesions that can cause visual impairment.

The longitudinal energy spread of ion beams extracted from an electron cyclotron resonance ion source
Authors: Angot J. , Tarvainen O. , Chauveau P. , Kosonen S.T. , Kalvas T. , Thuillier T. , Migliore M. , Maunoury L.
Published: April 2023

We present a study of factors affecting the energy spread of
ion beams extracted from a Charge Breeder Electron Cyclotron
Resonance Ion Source (CB-ECRIS). The comprehensive simulations,
supported by experiments with a Retarding Field Analyser (RFA),
reveal that the longitudinal and transverse energy spread of the
extracted beams are strongly affected by the electrostatic focusing
effects, namely the extraction geometry and plasma beam boundary, to
the extent that the electrostatic effects dominate over the magnetic
field induced rotation of the beam or the effect of plasma potential
and ion temperature. The dominance of the electrostatic focusing
effect over the magnetic field induced rotation complicates
parametric studies of the transverse emittance as a function of the
magnetic field strength, and comparison of emittance values obtained
with different ion sources having different extraction designs. Our
results demonstrate that the full ion beam energy spread, relevant
for the downstream accelerator, can be measured with the RFA only
when all ions are collected. On the contrary, studying the effect of
plasma properties (plasma potential and ion temperature) on the
longitudinal energy spread requires heavy collimation of the beam
accepting only ions near the symmetry axis of the beam for which the
electrostatic and magnetic effects are suppressed. As the extraction
system of the CB-ECRIS is similar to a conventional ECRIS, the
conclusions of the study can be generalised to apply for all high
charge state ECR ion sources. Finally, we present the results of
systematic plasma potential measurements of the Phoenix-type
CB-ECRIS at LPSC, varying the source potential, the microwave power
and the axial magnetic field srength. It was observed that the
plasma potential increases with the extraction magnetic field and
the microwave power.

The present work is devoted to the RF design and frequency sensitivity analysis of the 1500 MHz passive third harmonic superconducting cavity, optimizing the RF parameters of the cavity, and giving a frequency scheme for the cavity in fabrication. The reliability of the cavity during operation is taken as the main goal for the optimization of the geometrical parameters, and its structural and RF parameters are obtained with E
peak/E
acc of 2.17, B
peak/E
acc of 5.12 mT/(MV/m) and G · R/Q of 25052 at 2 K. A pair of fluted beam pipes are used to propagate the higher order modes (HOMs) of the harmonic cavity, allowing a smooth transition of the first dipole mode to the absorber located at room temperature area. For the frequency sensitivity analysis, the frequency variations of the cavity in fabrication are obtained by multi-physics coupling simulation in the paper, which gives the target frequency of the cavity between welding and preloading. After electron beam welding (EBW), the resonant frequency of the cavity should be maintained at 1500.096 MHz, and the pre-tuning target frequency is 1497.456 MHz. The slow tuning range is ±400 kHz, the fast-tuning range is 600 Hz, and the maximum allowable tuning force is 15 kN.

Published: April 2023

The aim of the presented article is to share experience gained throughout the course of two projects focused on precise grinding of a free-form glass optical element with the objective of achieving a surface shape error of less than approximately 10 μm PV before the subsequent polishing phases. Compared to spheres or aspheres machining, it is considerably more demanding, mainly due to the impossibility of using rotationally symmetric shape corrections. The developed and tested process combines a mechanical engineering approach based on the use of the current Computer Aided Design and Computer Aided Manufacturing software with their respective strengths and weaknesses and an optical engineering approach, for which the employment of CNC machines featuring precise control but low flexibility is typical. Therefore, attention is paid mainly to the description of particular process steps like CAD construction and CNC grinding step programming with regard to the necessary software and data handling, as well as the required parametrisation of the used machine equipment.
Arctic curves of the 20V model on a triangle
Authors: Di Francesco Philippe
Published: April 2023

We apply the Tangent Method of Colomo and Sportiello to predict the arctic curves of the Twenty Vertex model with specific domain wall boundary conditions on a triangle, in the Disordered phase, leading to a phase diagram with six types of frozen phases and one liquid one. The result relies on a relation to the Six Vertex model with domain wall boundary conditions and suitable weights, as a consequence of integrability. We also perform the exact refined enumeration of configurations.
Charging a quantum battery in a non-Markovian environment: a collisional model approach
Authors: Morrone Daniele , Rossi Matteo A C , Smirne Andrea , Genoni Marco G
Published: April 2023

We study the effect of non-Markovianity in the charging process of an open-system quantum battery. We employ a collisional model framework, where the environment is described by a discrete set of ancillary systems and memory effects in the dynamics can be introduced by allowing these ancillas to interact. We study in detail the behaviour of the steady-state ergotropy and the impact of the information backflow to the system on the different features characterizing the charging process. Remarkably, we find that there is a maximum value of the ergotropy achievable: this value can be obtained either in the presence of memoryless environment, but only in the large-loss limit, as derived in (Farina et al 2019 Phys. Rev. B 99 035421), or in the presence of an environment with memory also beyond the large-loss limit. In general, we show that the presence of an environment with memory allows us to generate steady-state ergotropy near to its maximum value for a much larger region in the parameter space and thus potentially in a shorter time. Relying on the geometrical measure of non-Markovianity, we show that in both the cases of an environment with and without memory the ergotropy maximum is obtained when the non-Markovianity of the dynamics of the battery is zero, possibly as the result of a non-trivial interplay between the memory effects induced by, respectively, the environment and the charger connected to the battery.
Extending the extended dynamic mode decomposition with latent observables: the latent EDMD framework
Authors: Ouala Said , Chapron Bertrand , Collard Fabrice , Gaultier Lucile , Fablet Ronan
Published: April 2023

Bernard O Koopman proposed an alternative view of dynamical systems based on linear operator theory, in which the time evolution of a dynamical system is analogous to the linear propagation of an infinite-dimensional vector of observables. In the last few years, several works have shown that finite-dimensional approximations of this operator can be extremely useful for several applications, such as prediction, control, and data assimilation. In particular, a Koopman representation of a dynamical system with a finite number of dimensions will avoid all the problems caused by nonlinearity in classical state-space models. In this work, the identification of finite-dimensional approximations of the Koopman operator and its associated observables is expressed through the inversion of an unknown augmented linear dynamical system. The proposed framework can be regarded as an extended dynamical mode decomposition that uses a collection of latent observables. The use of a latent dictionary applies to a large class of dynamical regimes, and it provides new means for deriving appropriate finite-dimensional linear approximations to high-dimensional nonlinear systems.

-norm declinations of the boundary electrode current from the given current pattern and boundary electrode voltages from the measurements. EIT optimal control problem is fully discretized using the method of finite differences. The existence of the optimal control and the convergence of the sequence of finite-dimensional optimal control problems to EIT coefficient optimal control problem is proved both with respect to functional and control in 2- and 3-dimensional domains.

Quasi-reversibility method and neural network machine learning for forecasting of stock option prices
Authors: Klibanov Mikhail , Golubnichiy Kirill , Nikitin Andrey
Published: April 2023

This paper presents a novel way to predict options price for one day in advance, utilizing the method of Quasi-Reversibility for solving the Black-Scholes equation. The Black-Scholes equation is solved forwards in time, which is an ill-posed problem. Thus, Tikhonov regularization via the Quasi-Reversibility Method is applied. This procedure allows to forecast stock option prices for one trading day ahead of the current one. To enhance these results, the Neural Network Machine Learning is applied on the second stage. Real market data are used. Results of Quasi-Reversibility Method and Machine Learning method are compared in terms of accuracy, precision and recall.
Numerical reconstruction for 3D nonlinear SAR imaging via a version of the convexification method
Authors: Khoa Vo , Klibanov Michael , Powell William , Nguyen Loc
Published: April 2023

This work extends the applicability of our recent convexification-based algorithm for constructing images of the dielectric constant of buried or occluded target. We are orientated towards the detection of explosive-like targets such as antipersonnel land mines and improvised explosive devices in the non-invasive inspections of buildings. In our previous work, the method is posed in the perspective that we use multiple source locations running along a line of source to get a 2D image of the dielectric function. Mathematically, we solve a 1D coefficient inverse problem for a hyperbolic equation for each source location. Different from any conventional Born approximation-based technique for synthetic-aperture radar, this method does not need any linearization. In this paper, we attempt to verify the method using several 3D numerical tests with simulated data. We revisit the global convergence of the gradient descent method of our computational approach.
Active control of scalar Helmholtz fields in the presence of known impenetrable obstacles
Authors: Besabe Lander , Onofrei Daniel
Published: April 2023

In this paper, we consider the question of actively manipulating scalar Helmholtz fields radiated by a given source that is supported on a compact domain. We claim that the field radiated by the source approximates given scalar fields in prescribed exterior regions while maintaining desired far field patterns in prescribed directions in the presence of exterior known impenetrable obstacles. For simplicity of the exposition, we consider a simplified geometry with only one obstacle, one region of control, and a finite number of far field directions and present a theoretical argument for our claim stated above. Afterwards, we also show how it can be elementarily extended to the general case. Further, we construct a numerical scheme to compute these boundary inputs using the method of moments, the addition theorem, Tikhonov regularization, and Laplace spherical functions.
A New Legal Form for Social Enterprises in Asia
Authors: Lim Ernest
Published: April 2023

This Article argues that there should be a new legal form for social enterprises in Asia that takes into account the distinctive contexts within which different types of social enterprises operate in the different Asian jurisdictions. In order to understand and evaluate social enterprise law, this Article advances an analytic framework consisting of (i) corporate purpose; (ii) directors’ duties; (iii) decision-making powers; (iv) reporting and certification; and (v) distribution of dividends, assets, and tax benefits. Using the four leading common law jurisdictions (Singapore, Hong Kong, Malaysia, and India) as a case study, the Article challenges the dominant assumption that the existing legal forms in Asia are adequate and appropriate to achieving the aims of social enterprises in Asia. It also critiques the legal forms for social enterprises in the United Kingdom and the United States, and finds them unsuitable for adoption by the Asian jurisdictions.
