SIMULATION OF DYNAMIC PROCESSES IN A p - i - n DIODE BY THE METHODS OF PERTURBATION THEORY
Authors: Bomba Andrii Yaroslavovych , Moroz Igor Petrovych
Published: May 2024

In the paper a mathematical model of the dynamic process of the electron-hole plasma formation in the active region ( i - region) of a semiconductor
p - i - n - diode in the direct bias mode with a harmonic signal fed on the diode is developed. The basis of the model is a nonlinear nonstationary sin-
gularly perturbed boundary value problem for a system of continuity equations of electron-hole currents and Poisson's equation. The algorithm for searching the charge carrier concentration distributions and the potential distribution is based on the asymptotic method of boundary functions and the Fourier method. In the course of the research, a technique for decomposing a nonlinear problem based on the development of perturbation theory me- thods was proposed. The initial nonlinear problem is reduced to a recurrent sequence of linear stationary boundary value problems, solved by classical and partially original analytical-numerical methods. The identification of the boundary functions in the solution of the problem provides, in particular, in contrast to the classical approximation of ambipolar diffusion, an adequate description of the electric field strength behavior in the active region of p - i - n - diodes. The obtained research results shed light on the peculiarities of the formation of the impedance characteristics of p - i - n - structures. The results of the work reveal more deeply the nature of the physical processes in the studied technical system and are aimed at improving the methodology for modeling and designing control semiconductor devices.
INVESTIGATION OF STABILITY OF NONLINEAR NORMAL MODES OF DISSIPATIVE SYSTEM OSCILLATIONS UNDER INFLUENCE OF MAGNETIC FIELD
Authors: Surhanova Yuliia Eduardivna , Mikhlin Yurii Volodymyrovych
Published: May 2024

In the paper the dynamics of the vibrating system consisting of two pendulums connected by elastic coupling and located in a magnetic field is studied. A case is considered when masses of the pendulums differ significantly. Under the influence of various external factors, such as magnetic forces and loads, which are present in engineering systems, the analysis of vibration regimes in non-linear systems becomes more complex. Here the nonlinear normal connected vibration mode in a system under consideration is analyzed. We have investigated the influence of changes in system parameters on the vibra- tion mode for both small and large initial angles of the pendulum deflection. Both the analytical method, namely, the method of many scales, and nu- merical simulations based on the fourth order Runge – Kutta method are used to analyze the vibration regimes. The initial conditions used to calculate this mode were determined analytically. The simulation includes construction of phase diagrams, trajectories in configuration space, and spectra, which allows us to evaluate the system dynamics, including both regular and complex regimes of vibrations. To study the stability of the vibration mode, a numerical-analytical method associated with the Lyapunov stability criterion is used. The stability of the mode is determined by assessing orthogonal deviations with respect to the corresponding modal trajectories in the configuration space. Regions of instability on planes and in the space of the system parameters are obtained.
ANALYSIS OF THE CRITERIA OF SUCCESSFUL ORGANIZATION OF PRODUCTION ACTIVITIES OF THE ENTERPRISE
Authors: Nikolaienko Sergii
Published: May 2024

To satisfy its own economic interests, any manufacturing enterprise directs its financial, material and human resources to the production of such products, which would simultaneously be in demand among consumers and at the same time bring the maximum possible profits to the enterprise and its owners. At the same time, active competition between production enterprises in the conditions of a modern market economy is the most important condition for their existence. And modern world trends in the form of globalization, rapid informatization of business processes and automation of production additionally demand constant adaptation to them from production enterprises. In addition, less predictable factors must be taken into account: epidemics (such as Covid-19), military conflicts, financial crises, etc.
The work analyzes the minimally necessary criteria for the successful organization of the production activity of the enterprise. Factors that significantly affect the organization of production activities have been identified. The principles on which the organization of the production activity of the enterprise is based are determined. The considered functions of management of the production activity of the enterprise. The methods used in the management of production activities are presented. The currently existing production models (concepts) have been determined. Possible strategies of production activities are analyzed. The use of models (concepts) and strategies within the framework of the operational management system of the enterprise is considered. A set of necessary economic indicators is proposed, which, in combination with a system of operational management of the enterprise's activities, can ensure the success of production activities.
Thus, the principles, concepts, strategies and operational management system of the enterprise discussed above together with an optimally selected set of economic indicators in the process of organizing production determine the success of the enterprise's production activity.

Article discusses the issues of diplomatic and economic protocol and ethics, shedding light on the intricate interplay between international relations and economic activities. Diplomatic protocol, with its established conventions and rituals, plays a crucial role in shaping the discourse between nations, fostering cooperation, and mitigating conflicts. Economic protocol, on the other hand, governs the conduct of nations and businesses in the global marketplace, influencing trade agreements, investment practices, and financial interactions.
The examination of these protocols within the framework of ethics becomes imperative as it explores the moral dimensions of diplomatic and economic engagements. Ethical considerations in diplomacy encompass matters of respect, transparency, and adherence to international law, aiming to promote peaceful coexistence and equitable collaboration. Similarly, in the realm of international economics, ethical principles guide decisions regarding resource allocation, corporate responsibility, human rights protection, and the fight against corruption.
By delving into the ethical aspects of diplomatic and economic protocols, the article seeks to contribute to a deeper understanding of the values that underpin international interactions. It emphasizes the importance of fostering ethical practices in diplomacy and economic relations, ultimately striving to create a global landscape that values fairness, responsibility, and mutual respect.
The current significance of business protocol is underscored in light of its strategic importance in facilitating effective communication and collaboration between nations and businesses. The challenges faced by business protocol in the modern global business arena are thoroughly scrutinized, addressing issues such as cultural diversity, technological advancements, and the need for constant adaptation. In summary, this comprehensive analysis contributes to a nuanced understanding of the multifaceted role of business protocol in international economic relations, shedding light on its historical roots, contemporary significance, and the evolving challenges it faces in the globalized business landscape.

A risk management framework for Taenia saginata eggs in recycled water to minimise the risk of Cysticercus bovis in cattle
Authors: Stevens Daryl , McDonald Ann , Pointon Andrew
Published: May 2024

To use water recycled from sewage (recycled water), the helminth egg from T. saginata requires management to minimise the risk of causing Cysticercus bovis (CB) in cattle when the egg is ingested. Recent advances in the risk management of helminth eggs in recycled water have allowed a risk management approach to be developed by the cattle production sector and low risk recycled water defined (i.e. fit for the purpose of cattle production). The approach described here connects the risk-based management systems from the recycled water, cattle production and processing sectors. The recent literature was also reviewed to update methods for achieving the required LRV to provide low risk recycled water. The connection between the two sectors allows improvements and cost savings for both sectors by providing a rational quantitative approach to CB management in cattle where recycled water is used.
MALE PATIENTS COMMUNICATING RESTORED MENTAL HEALTH BY THEIR FACIAL EXPRESSIONS AND GENTLEMANLY PERSONA AT THE GRAHAMSTOWN LUNATIC ASYLUM, 1890–1907
Authors: Du Plessis Rory
Published: May 2024

During the medical superintendence of Dr Thomas Duncan Greenlees at the Grahamstown Lunatic Asylum, from 1890 to 1907, he was watchful of his patients’ appearances, facial expressions and conduct. Of particular interest, Greenlees would closely monitor the patients’ faces to identify if there were any involuntary expressions that were indicators of underlying emotional unease or mental distress. Greenlees thus regarded involuntary facial expressions as a litmus test of a patient’s recovery, but it was the patient’s conscious facial expressions, as well as their presentation of upstanding behaviour and conduct, that signalled to the staff that they were self-composed, and hence on the path towards convalescence. In this article, I explore how three white male patients of the Asylum communicated their convalescence and/or restored mental health to the staff by posing for their casebook photographs and by presenting a gentlemanly persona. To this end, I interpret the photographs of the three men alongside entries from their casebooks as an interface to explore dimensions of time that lie outside the split second that was captured by the camera lens. In doing so, the glimpses of a patient’s agency and appearance in a photograph can be understood and compared with their performance of a gentlemanly persona that was recorded in the casebooks.
REFLECTING ON ANALOGUE FACES AND DIGITAL MASKS THROUGH MISSION: IMPOSSIBLE (1996-2023)
Authors: Broodryk Chris
Published: May 2024

This article uses the idea and practice of the mask and masking technology in the popular Mission: Impossible film franchise to critically consider the tensions between digital and analogue. In the Mission: Impossible films, the masks are a core component of the films’ intrigue, and they serve the plot dynamics of each franchise entry while also revealing ever-sophisticated diegetic film technologies that make these silicone-based masks increasingly hyper-realistic in spy-craft and anti-surveillance deception. This article demonstrates how the mask is an identity technology that qualifies the persona as potentially deceptive and duplicitous as it relies on a convincing presentation of a character’s self that does not accurately reflect the interiority of this character, and on a betrayal of trust of the affective investment of a particular micro-publics. As such, the viewer reflects on facial representation not only in terms of verisimilitude, but also veracity. Within a context of techno est ubique, the mask has evident transformative capacities as a temporary interface with the world and as a remediation technology. However, the mask is also a precarious technology because it is highly visible and needs monitoring for proper presentation and error. It is a seamless technology, which evokes further reflections on photorealism and deepfakes. Additionally, digital comes to denote ‘dead’, and the digital mask of especially the later Mission: Impossible films – identifiable by its skeuomorphic qualities – challenges the continued existence of the analogue (organic face) as mask and related appearance replication technologies come to replace human faces and bodies entirely.

Canine distemper virus (CDV) belongs to morbillivirus, including measles virus (MeV) and rinderpest virus, which causes serious immunological and neurological disorders in carnivores, including dogs and rhesus monkeys, as recently reported, but their vaccines are highly effective. The attachment glycoprotein hemagglutinin (CDV-H) at the CDV surface utilizes signaling lymphocyte activation molecule (SLAM) and Nectin4 (also called poliovirus-receptor-like-4; PVRL4) as entry receptors. Although fusion models have been proposed, the molecular mechanism of morbillivirus fusion entry is poorly understood. Here, we determined the crystal structure of the globular head domain of CDV-H vaccine strain at 3.2 Å resolution, revealing that CDV-H exhibits a highly tilted homodimeric form with a six-bladed β-propeller fold. While the predicted Nectin4 binding site is well-conserved with that of MeV-H, that of SLAM is similar but partially different, which is expected to contribute to host specificity. Five N-linked sugars covered a broad area of the CDV-H surface to expose receptor binding sites only, supporting the effective production of neutralizing antibodies. These features are common to MeV-H, although the glycosylation sites are completely different. Furthermore, real-time observation using high-speed atomic force microscopy revealed highly mobile features of the CDV-H dimeric head via the connector region. These results suggest that sugarshielded tilted-homodimeric structure and dynamic conformational changes are common characteristics of morbilliviruses and ensure effective fusion entry and vaccination.
Soil climate underpins year effects driving divergent outcomes in semi-arid cropland to grassland restoration
Authors: Mahood Adam , Barnard David , Macdonald Jacob , Green Tim , Erskine Robert
Published: May 2024

Converting croplands to grasslands can restore ecosystem functions and services, but there is uncertainty about why some restoration treatments succeed and others do not. One likely explanation for variation in restoration outcomes is that interannual variation in the drivers of community assembly, or “year effects”, are often overlooked in restoration planning. Existing restoration strategies tailor species compositions of seed mixes according to long-term climate means and hardiness zones. However, individual years typically deviate from average climate norms such that restoration activities may be better informed by recent conditions than by climate averages. We monitored a 109 ha field in northeastern Colorado that was converted from a winter wheat-fallow rotation to native perennial grassland via seeding. The same seed mix was used to seed 6 of 12 120 m strips in 2013 (drier) and 6 in 2014 (wetter). In the strips seeded in 2013, only one native grass and one shrub species from the seed mix established widely, whereas in 2014 all native grasses established. Higher soil moisture preceding seed application was positively associated with perennial grasses, while rhizomatous grasses, shrubs and introduced annuals were associated with other variables. After seeding, high summer soil moisture was positively associated with a rhizomatous C3 grass, while the planted C4 bunchgrasses were negatively associated with high summer soil moisture and positively associated with high fall soil temperatures. We found evidence of facilitatory interactions between grasses and forbs, and antagonistic interactions between native perennial grasses and non-native annuals. Our results suggest that the conditions immediately before and after planting govern community assembly and leave a lasting legacy and should be considered in planning treatments. We suggest composing seed mixes that are tailored to commonly encountered extremes of temperature and moisture availability. Land managers can also use split-seeding or repeated seeding approaches, within or between years as bet-hedging 2 3 strategies. The development of more flexible funding mechanisms could allow for regional go/no-go climate thresholds to avoid wasting resources.

Context-aware Neural Machine Translation can potentially enhance automated translation quality through effective modelling of context beyond the sentence level. However, suitable corpora for contextual modelling are still scarce, presenting a significant challenge for the training and evaluation of context-aware systems. To address this challenge, we describe \textsc{tando^+}, a document-level corpus for the under-resourced language pairs Basque-French and Basque-Spanish. We provide a detailed description of this corpus, which is to be shared with the scientific community. The corpus comprises parallel data from diverse domains (literature, subtitles, and news) and incorporates context-level information. Additionally, it provides manually crafted contrastive test sets for Basque-Spanish, designed for comprehensive assessment of gender and register contextual phenomena. Additionally, we train and evaluate sentence-level baseline models and several state-of-the-art contextual variants. Our results and analyses indicate that the corpus is well-suited to train and evaluate context-aware machine translation systems for the two selected under-resourced language pairs.

Published: May 2024

Oxidative dry reforming of ethanol is a promising route to utilize CO2, a greenhouse gas and ethanol, a renewable feedstock in the production of synthesis gas (syngas-a mixture of H2 and CO). It is a feedstock for Fischer-Tropsch (F-T) process to produce synfuels and valuable chemicals. Syngas is mainly produced by dry reforming of methane, but its continuous deployment urges to find an alternative feedstock such as ethanol. The present work aims to simulate syngas production from ethanol focusing on the reduction of carbon formation and energy requirement. Thermodynamic equilibrium analysis for dry reforming and oxidative dry reforming of ethanol are carried out following Gibbs free energy minimization method using Aspen Plus simulation tool. The reaction temperature and feed mole ratio (O2/CO2/ethanol) are varied to obtain equilibrium moles of different products including solid carbon at atmospheric pressure. Syngas yield increases from 1 to 5.2 moles with a suitable ratio of H2/CO when temperature is increased from 500 to 800 0C at CO2/ethanol mole ratio of 1 at atmospheric pressure. The addition of oxygen does not affect syngas production much but drastically reduces carbon formation and the amount of energy requirements. Carbon formation becomes negligible when 0.2 moles O2 in feed stream is added at 775 0C and atmospheric pressure, while in the absence of oxygen 0.392 moles carbon is formed at the otherwise identical operating conditions. At above conditions, addition of 0.2 moles of O2 co-feed can reduce energy requirements of the reformer up to 13.35%.

Purpose:
Growth of macular neovascularization (MNV) associated with the development of macular atrophy in some eyes has been observed in neovascular age-related macular degeneration (nAMD) under effective anti-vascular endothelial growth factor (VEGF) therapy. We aimed to evaluate the influence of growing MNV and macular atrophy development on the sensitivity of the overlaying retina.
Methods:
Prospective pilot study on nAMD patients undergoing long-term anti-VEGF therapy (IVAN treatment strategy) that had also undergone microperimetry testing. MNV extension and, if present, associated macular atrophy defined as complete retinal pigment epithelial and outer retina atrophy (cRORA) were identified on OCT volume scans and transposed onto en-face NIR images. Mesopic microperimetry performed at the same visit was superimposed. Retinal sensitivity above the MNV and the surrounding retina was compared, excluding areas of cRORA.
Results:
26 eyes (19 f, 7 m; age 79.3 ± 5.7 y; fu 4.0 ± 1.8 y; 7.4 ± 2.5 inj./y) were classified into “no cRORA” group (n=11) and “cRORA” group (n=15). In the “no cRORA” group, BCVA was significantly higher, and mean retinal sensitivity above the MNV did not differ from the surrounding retina (20.9 ± 2.8 vs. 22.0 ± 2.4, p=.33), while in the “cRORA” group, a lower sensitivity above the MNV was observed (16.2 ± 3.4 vs 19.9 ± 2.0, p=.001).
Conclusion:
In the absence of cRORA, retinal sensitivity above the MNV did not differ significantly from that of the surrounding retina. These results support the hypothesis that MNV itself may not be detrimental if cRORA can be prevented.

Externalized phosphatidylserine (PS) on cell membranes is well-known as a late stage “eat me” signal for dead cells that is routinely used as standard marker of apoptotic cell death. Here, we show that unexpectedly, externalized PS is not just a marker of dead cells but may play an active role in regulating early phases of neuronal death in stroke. We found that transmembrane protein 30A (Tmem30a), the β-subunit of P4-ATPases, were increased in the penumbra in two types of stroke models. Tmem30a upregulation was associated with less PS exposure and neurological benefits in models of ischemia/reperfusion, but not in permanent ischemia. Furthermore, treatment with recombinant Annexin V, having a high affinity with phosphatidylserine, decreased PS exposure and mitigated neurological impairments in wild-type mice after ischemia/reperfusion, but not in Tmem30a knockout mice. Mechanistically, mitigation of PS exposure, medicated by Tmem30a/Annexin V, led to decreased expression of apoptosis and necroptosis markers in neurons of peri-infarct areas and led to improved neurologic outcomes. In a proof-of-concept analysis of acute stroke patients, increased plasma Annexin V were associated with early neurological improvement in patients with salvageable penumbra after endovascular treatment. Taken together, these findings suggest that Tmem30a-mediated externalization of PS may be a novel mechanism and target in ischemic stroke.
Diagnosis and Management of Inferior Alveolar Nerve Injury Caused by Calcium Hydroxide Extrusion during Root Canal Treatment: Case Report

Published: May 2024

This report highlights a rare occurrence of inferior alveolar nerve injury resulting from calcium hydroxide extrusion during endodontic treatment. The patient experienced severe pain and paraesthesia in the lower right lip following root canal treatment due to inadvertent overflow of calcium hydroxide into the inferior alveolar nerve canal. No surgical intervention was performed, the patient received non-steroidal anti-inflammatory analgesics and Vitamin B complex injections to manage the symptoms. At six months, complete resorption of the root canal material occurred, resulting in further reduction in paraesthesia. Two-year follow-up, complete disappearance of paraesthesia occurred. The importance of the preoperative radiographs is highlighted. The lack of radiographic assessment at the patient's request led to calcium hydroxide overflow.

The Cucurbitaceae family accumulates hydrophobic organic pollutants in their aerial parts at high concentrations. Major latex-like proteins (MLPs) identified in Cucurbita pepo bind to hydrophobic organic pollutants in roots, forming complexes that are transported via xylem vessels to the plant’s aboveground parts. However, soil remediation of hydrophobic organic pollutants utilizing MLPs has not been established. In this study, the uptake of hydrophobic organic pollutants was promoted by C. pepo through the upregulation of MLP genes by agrochemical treatment. It was found that probenazole, an active ingredient in the agrochemical Oryzemate, upregulated the promoter activity of MLP genes in the roots of transgenic tobacco plants. Oryzemate treatment increased the amount of MLPs in the roots and xylem sap of C. pepo. Oryzemate treatment slightly increased and significantly decreased the concentration of the hydrophobic organic pollutant pyrene in the xylem sap of C. pepo cultivated in high- and low-contamination soils, respectively. Probenazole competitively inhibits the binding of MLPs to pyrene, thereby suppressing its uptake by C. pepo in low-contamination soil. This study demonstrates that Oryzemate possesses dual effects: effective phytoremediation and safe crop production, depending on the soil contamination level.

Intravenous leiomyomatosis (IVL) is a histologically well differentiated smooth muscle tumor with aggressive behavior, capable of extending throughout the venous system. Due to its rarity, systematic studies on IVL are limited. We conducted a comprehensive multi-omics study, collecting tissues from IVL, uterine fibroid, and normal myometrium. Single-cell RNA sequencing analysis revealed a significant difference in cell composition between IVL and uterine fibroid. H&E staining demonstrated more frequent hydropic change and hyalinization, with decreased vascular density in IVL tissues compared to both normal myometrium and uterine fibroid. Proteomics analysis in 8 paired IVL and normal myometrium fresh frozen tissue identified differentially expressed proteins mainly enriched in focal adhesions and regulation of the actin cytoskeleton. The most frequently involved chromosomes included deletions in 10q22.2, 10q24.32, 13q14, and 13q21-31. Correlation analyses highlighted chromosome 10q as the most frequent cytoband, with corresponding proteins involved in regulating focal adhesions and the cytoskeleton. Integrated analysis between pathological and clinical characteristics indicated that chromosome 10q deletion and vascular morphology in IVL could serve as important markers predicting aggressive behavior. Our study illuminates the pathological and molecular changes associated with IVL, offering insights that may contribute to establishing new directions for IVL treatment.
