Modelling of Energy-Dependent Electron Interactions in the Earth’s Mesosphere
Authors: Campbell Laurence , Brunger Michael J. 
Published: March 2023

Electrons are produced in the Earth’s quiet nighttime mesosphere by ionization by cosmic rays and ionization of NO by Lyman-α radiation. They are removed by attachment or recombination processes that are usually assumed in modelling to occur at the ambient temperature. However, the electrons have initial energies that are much higher than at thermal equilibrium, and so must have a range of energies as they progress towards equilibrium via interactions with atoms and molecules. As attachment and recombination rates are dependent on the electron energy, it is possible that modelling that considers the actual energy of the electrons will give different results to those based on assuming that the electrons are at the ambient temperature. In this work, starting with electrons at a higher initial energy, the detailed electron interactions (including elastic scattering and vibrational excitation of molecules) are tracked in a time-step simulation. This simulation is implemented by treating electrons in subranges of the electron energy spectrum as chemical species. This allows an investigation of two phenomena in the nighttime mesosphere: the origin of the D-region ledge and the production of radiative emissions from vibrationally excited molecules. It is found that there is negligible difference in the electron densities calculated using the ambient temperature or detailed interaction models, so this study does not provide an explanation for the D-region ledge. However, in the latter model, emissions at various wavelengths are predicted due to reactions involving vibrationally excited molecules. It is also found, using the time-step calculation, that it would take several hours for the predicted electron density to approach equilibrium.

Published: March 2023

Nutrient resorption is an important strategy for plants to retain critical nutrients from senesced leaves and plays important roles in nutrient cycling and ecosystem productivity. As a main economic crop and soil and water conservation species, Wuyi Rock tea has been widely planted in Fujian Province, China. However, foliar nutrient resorptions of Wuyi Rock tea cultivars have not been well quantified. In this study, three Wuyi Rock tea cultivars (Wuyi Jingui, Wuyi Rougui, and Wuyi Shuixian) were selected in the Wuyishan National Soil and Water Conservation, Science and Technology Demonstration Park. Resorption efficiencies of nitrogen (NRE), phosphorus (PRE), and potassium (KRE) along with their stoichiometric characteristics were determined. PRE of the three tea cultivars was significantly higher than KRE and NRE, indicating that tea cultivars were P limited due to low P availability for the tea growth. With the exception of Wuyi Rougui, leaf N and P contents of the other two cultivars (Wuyi Jingui and Wuyi Shuixian) had strong homeostasis under the changing soil environments. Leaf thickness and specific leaf area were positively and significantly correlated with KRE, and total chlorophyll concentration was positively correlated with NRE, indicating that leaf functional traits can be used as indicators for nutrient resorption status. Wuyi Rock tea cultivars had strong adaptabilities to the environments and had high carbon sequestration capabilities; thus, they and could be introduced into nutrient-poor mountainous areas for both economic benefits and soil and water conservation.

Published: March 2023

Two herbal plants, Akebia quinata D. leaf/fruit and Clitoria ternatea L. flower, well-known in traditional medicine systems, were investigated using a non-target effect-directed profiling. High-performance thin-layer chromatography (HPTLC) was combined with 11 different effect-directed assays, including two multiplex bioassays, for assessing their bioactivity. Individual active zones were heart-cut eluted for separation via an orthogonal high-performance liquid chromatography column to heated electrospray ionization high-resolution mass spectrometry (HPLC–HESI-HRMS) for tentative assignment of molecular formulas according to literature data. The obtained effect-directed profiles provided information on 2,2-diphenyl-1-picrylhydrazyl scavenging, antibacterial (against Bacillus subtilis and Aliivibrio fischeri), enzyme inhibition (tyrosinase, α-amylase, β-glucuronidase, butyrylcholinesterase, and acetylcholinesterase), endocrine (agonists and antagonists), and genotoxic (SOS-Umu-C) activities. The main bioactive compound zones in A. quinata leaf were tentatively assigned to be syringin, vanilloloside, salidroside, α-hederin, cuneataside E, botulin, and oleanolic acid, while salidroside and quinatic acids were tentatively identified in the fruit. Taraxerol, kaempherol-3-rutinoside, kaempferol-3-glucoside, quercetin-3-rutinoside, and octadecenoic acid were tentatively found in the C. ternatea flower. This straightforward hyphenated technique made it possible to correlate the biological properties of the herbs with possible compounds. The meaningful bioactivity profiles contribute to a better understanding of the effects and to more efficient food control and food safety.

Published: March 2023

Automated hand gesture recognition is a key enabler of Human-to-Machine Interfaces (HMIs) and smart living. This paper reports the development and testing of a static hand gesture recognition system using capacitive sensing. Our system consists of a 6×18 array of capacitive sensors that captured five gestures—Palm, Fist, Middle, OK, and Index—of five participants to create a dataset of gesture images. The dataset was used to train Decision Tree, Naïve Bayes, Multi-Layer Perceptron (MLP) neural network, and Convolutional Neural Network (CNN) classifiers. Each classifier was trained five times; each time, the classifier was trained using four different participants’ gestures and tested with one different participant’s gestures. The MLP classifier performed the best, achieving an average accuracy of 96.87% and an average F1 score of 92.16%. This demonstrates that the proposed system can accurately recognize hand gestures and that capacitive sensing is a viable method for implementing a non-contact, static hand gesture recognition system.

Authors: Yılmaz Yılmaz , Akdemir Ahmet Ocak 
Published: March 2023

Mathematical concepts are aesthetic tools that are useful to create methods or solutions to real-world problems in theory and practice, and that sometimes contain symmetrical and asymmetrical structures due to the nature of the problems. In this study, we investigate whether the sequence spaces Xpq, 0≤p<∞, and X∞, which are constructed by q-Cesáro matrix, satisfy some of the further properties described with respect to the bounded linear operators on them. More specifically, we answer to the question: “Which of these spaces have the Approximation, Dunford-Pettis, Radon–Riesz and Hahn–Banach extension properties?”. Furthermore, we try to investigate some geometric properties such as rotundity and smootness of these spaces.

PHENOMENOLOGICAL RESEARCH OF IMAGINATION IN SCHIZOPHRENIA SPECTRUM DISORDERS AS A CONCEPTUAL FRAMEWORK FOR UNDERSTANDING PSYCHOTHERAPEUTIC PROCESSES AND RECOVERY STRATEGIES
Authors: Pushko Ye. 
Published: March 2023

Although imagination abnormalities are frequent and handicapping in schizophrenia spectrum disorders (SSDs), psychopathology lacks a conceptual framework for modeling imagination disorders. Recently, in connection with the “imaginary turn” in phenomenology, translational approaches between philosophy and psychopathology have been sought. The purpose of the article is the presentation and analysis of modern foreign phenomenological studies of imagination in SSDs by a group of researchers headed by A. Rasmussen and J. Parnas, for the possible implementation of the results in domestic practice. The author first examines the features of anomalous fantasy and imagination in SSDs from the phenomenological point of view and then presents an overview of the EAFI instrument for a semistructured, phenomenological study of anomalous fantasy and imagination through interviews. Then the author analyzes the theoretical and practical implications of such research for understanding psychotherapeutic processes and recovery strategies. The studied disorders of imagination are characterized by three phenomenological dimensions: 1) perceptualization of imagery: the experience acquires certain quasi-perceptual qualities, such as spatialization, spatiotemporal constancy and explorabilty; 2) autonomization of imagery with a quasi-involuntary flow and a sense of empirical distance between the conscious image and the sense of agency; and 3) erosion of irreality: whereas the imagination is normally lived with an ever-present character of unreality, people with SSDs can experience vivid imagery without a clear separation with the real world. Rasmussen et al. not only describe clinical experience, they also offer a conceptual model of imagination disorders as expressions of minimal self-disorders (disorders of ipseity). The researchers hypothesize that impaired ipseity itself is the core generative disorder of schizophrenia, and positive/negative symptoms derive from this core phenotype. Thus, imagination is understood as a mental domain that affects the underlying disorder, meaning that imagination has the same status as all other modes of intentional consciousness (such as perception or memory). T. Gozé and I. Fazakas go further and suggest a phenomenological distinction between fantasy and imagination, which resembles the distinction between body schema and body image.
Detection of Hemodialysis Venous Needle Dislodgment Using Venous Access Pressure Measurements: A Simulation Study
Authors: Frinak Stanley , Kennedy John , Zasuwa Gerard , Passalacqua Karla D. , Yee Jerry 
Published: March 2023

Key Points

Hemodialysis machine pressure alarms may not detect venous needle dislodgment when patients have changes in venous pressure.A cross-sectional analysis of hemodialysis treatment data identified the occurrences of venous pressure changes that would make it hard to trigger a machine alarm.A proof-of-concept use of a data analytic–derived algorithm for the detection of venous needle dislodgments was demonstrated.

Background:
In rare instances, hemodialysis venous needles may become dislodged, and when left undetected, this can lead to severe injury or death. Although dialysis machines have alarms to detect venous needle dislodgment (VND), their range of detection is limited. An understanding of the clinical conditions that may lead to missed needle dislodgments is needed for the development of more robust detection systems.

Methods:
We created a sham dialysis circuit with a Fresenius 2008K dialysis machine for in vitro simulation testing of machine alarm behavior under variable conditions. The circuit used a blood substitute and mimicked a patient's venous access site. We varied blood flow rate, venous pressure (VP), and upward drift in VP and analyzed the time to alarm for the machine and an improved alarm algorithm. We also performed a cross-sectional retrospective study to identify the clinical occurrence of VP upward drift between September 1, 2016, and November 1, 2016, in patients on hemodialysis with an arteriovenous fistula.

Results:
Of 43,390 VP readings for 147 patients on hemodialysis, 16,594 (38%) showed an upward drift in VP (range 20–79 mmHg), with a mean±SD increase of 11±18 mm Hg within 20±14 minutes. A total of 19 VND simulations under different VP and blood flow parameters resulted in 19 (100%) algorithm alarm activations. Only eight simulations (42%) activated a machine alarm, and machine alarm activation time was longer than the algorithm activation time for all eight machine alarms (range 1–13 seconds).

Conclusions:
Patients can experience changes in VP during hemodialysis which may not trigger a machine alarm in the case of a VND. Our simulations showed that current dialysis machine alarm systems may not compensate for upward drift in VP, and improved algorithms for detecting needle dislodgment during hemodialysis are needed.

В ходе работы по созданию оптимального диагностического алгоритма для выявления множественной миеломы (ММ) и мониторинга ее терапии нами была проведена оценка эффективности использования цитогенетических исследований при диагностике и терапии ММ. Был проведен анализ 115 случаев ММ по результатам цитогенетического и цитологического исследований. Выявлено, что генетические нарушения имели место в 82,6% случаев ММ, а количество плазмоцитов в миелограмме могло иметь тенденцию к увеличению в зависимости от повышения сформированной цитогенетическим исследованием группы риска. Использование цитогенетического анализа и прогностическая стратификация на его основе признаны важными для создания алгоритма комплексной диагностики ММ. Показана необходимость цитогенетического анализа и анализа фенотипических особенностей клеток костного мозга в комплексной иммунохимической диагностике ММ и ее роль в скрининговых, мониторинговых и прогностических направлениях диагностики парапротеинемий.
In the course of work on the creation of an optimal diagnostic algorithm for the detection of multiple myeloma (MM) and monitoring of its therapy, we evaluated the effectiveness of the use of cytogenetic studies in the diagnosis and therapy of MM. MM 115 cases were analyzed based on the results of cytogenetic and cytological studies. It was revealed that genetic disorders occurred in 82.6% of MM cases, and the number of plasmocytes in the myelogram could tend to increase depending on the increase in the risk group formed by cytogenetic research. The use of cytogenetic analysis and prognostic stratification based on it are recognized as important for the creation of an algorithm for the complex diagnosis of MM. The necessity of cytogenetic analysis and phenotypic features of bone marrow cells in the complex immunochemical diagnosis of MM and its role in screening, monitoring and prognostic directions for the diagnosis of paraproteinemia is shown.
BERTOLT BRECHT AND SLOBODAN SCHNEIDER: WAR. RELIGION. WOMAN. THEATER
Authors: Bondareva O. 
Published: March 2023

Global issues fixed in the diachrony of world culture by the concept of "war", as well as modern methods of its aesthetic interpretation, are seen today as extremely promising for Ukrainian literary studies, which is now actively rethinking how and through which models the artistic representation of modern military events should take place and their reflection in experience/living.
The article offers a comparative literary analysis of B. Brecht's plays "Mother Courage and Her Children" and S. Schneider's "Snake Skin", in which, in the setting of the Thirty Years' War in Europe of the 17th century. contains deep ethical and philosophical reflections on the war as such and aesthetic reflections of two outstanding European playwrights on the war events of which they became contemporaries.
If B. Brecht’s play has many literary interpretations, including in Ukraine, S.Schneider’s play is being interpreted by Ukrainian literary studies for the first time. The intentions and artistic resources of both texts are compared through the conceptual series War – Religion – Woman – Theatre. In interpretation B. Brecht’s war is horizontal-processual and geographically dispersed, in S. Schneider’s she is cyclical and permanent, localized in a closed topographical and mythological space.
It is illustrated how playwrights conduct a dialogue with the world cultural tradition regarding religion/faith as a factor in modern war, the peculiarities of female figurative potential and female (not)subjectivity in aesthetic interpretations of war belonging to the 20th century are revealed, B. Brecht’s "epic theater" is compared and S. Schneider’s symbolic and allegorical theater. The study complements the problematic field of modern humanitarian reflections, activated by Russia’s full-scale attack on Ukraine in February 2022.
