Omicron emerged as the fifth variant of concern of SARS-CoV-2
coronavirus pandemic in late 2021 and rapidly overtook the previously
predominant Delta variants with a significantly faster transmission rate
and unique mutations on the spike gene. Hence, the ability to identify
viral variants rapidly and affordably in large number of patients, which
facilitates the monitoring of the transmission and clinical impact of
new variants, is needed to obtain information for updating the public
health policy. In this study, we evaluated the capability of two RT-PCR
and mass spectrometry-based SARS-CoV-2 variant classification platforms
to distinguish Delta, Omicron BA.1, and Omicron BA.2 variants in 618
COVID-19-positive samples from patients in Bangkok collected during
November 2011-March 2022. Analysis of the time-evolution pattern of
SARS-CoV-2 variant profiles indicated that the BA.1 and BA.2 possess up
to 2-3 times higher transmission rates than the Delta variant. Our study
showcases a cost-effective virus surveillance that enables a
quantitative estimation of variant-specific public health impact.

Authors: Mou Jing , Zhao Na , Chen Huilan , Feng Xiangchun
Published: August 2023

Background：Coffin-Siris syndrome（CSS,MIM 135900），is a
multiple congenital anomaly syndrome characterized by developmental
disability，coarse facial features，microcephaly and hypoplastic nails
of the fifth fingers or toes. CSS is caused by mutations in several
genes of the BRG1-associated factor（BAF） pathway including
SMARCA4. Individuals with SMARCA4 variants have been
previously reported and appear to display a variable phenotype.
Pathogenic variants in SMARCA4 genes have been associated with an
increasing risk of Coffin-Siris syndrome 4（MIM 614609）and Rhabdoid
Tumor Predisposition Syndrome2（RTPS2）. Methods：Whole-exome
sequencing（WES） was performed on an infant who presented with
developmental delay，feeding difficulties，and laryngomalacia. He was
also found to have testicular yolk sac tumor that has not been
previously reported in CSS. Results: Germline testing
identified a pathogenic variant in SMARCA4 c.2932C＞G.
Conclusions: To our knowledge，this is the first report of
testicular yolk sac tumor in an infant with a diagnosis of CSS with a
potential predisposition to RTPS2.

Published: August 2023

It is necessary to conduct research that will serve as a foundation for
pharmacotherapy for patients with mental illnesses. Digital data are
widely available, which has facilitated pharmacoepidemiology and, in
particular, observational studies on the efficacy of real-world
medications. The availability of large patient samples and the
availability to study understudied subpopulations in their natural
settings are benefits of pharmacoepidemiological research. This type of
research is also less expensive and takes less time to complete than
randomized controlled trials, making it more likely to address issues
relating to long-term outcomes, generic medication, and stopping
medication (deprescribing). We can expand Pharmacoepidemiological
techniques to pharmacovigilance and use them to help the development of
medicines that are already on the market. The non-randomized nature of
treatment selection, which causes confounding by indication, is a
drawback of observational pharmacoepidemiological studies. Active
comparison groups, within-individual designs, and propensity scoring are
potential solutions to this problem. To increase confidence in the
inferred causal relationships, it has strengthened many of the more
rigorous pharmacoepidemiology studies through the triangulation of
multiple analytical approaches. It is encouraging that guidelines are
considering evidence from reliable observational pharmacoepidemiological
studies besides randomized controlled trials considering advancements in
data resources and analytical methods. cooperation among
pharmacoepidemiology researchers and guideline writers may enable
researchers to respond that important policymakers’ questions and
guarantee that findings are included in the evidence base. To fully
capitalize on future opportunities, it will be necessary to advance
statistical and data science techniques, general engagement, and
capacity building (data resources and researcher base).

Published: August 2023

The diversity–productivity relationship in grasslands is predominantly
positive but also highly variable because of its complex influencing
mechanisms in natural ecosystems. In this study, we investigated plant
diversity, biomass, and associated drivers (e.g., climate, soil, and
plant traits) along an elevational gradient in grasslands in southwest
China. Grassland biomass decreased significantly, but grassland
diversity increased with increasing elevation. Consequently, a
significant negative relationship between grassland biomass and
diversity was detected along the elevational gradient. We also observed
that the negative relationship was primarily driven by climatic factors
(i.e., temperature and precipitation) and plant stoichiometric traits
(i.e., phosphorus limitation) rather than by soil properties at a
regional scale. This is inconsistent with previous studies on the
positive diversity–productivity relationship, which might weaken the
effects of climatic factors at the regional scale. Our results revealed
that the negative relationship between diversity and productivity in
grasslands was shaped by the combined effects (climate and plants) on
productivity and diversity in grasslands.
SOURCE ANALYSIS OF DAYTIME MSTID USING OBSERVATION AND SIMULATION
Authors: Jonah Olusegun , Jonah O F , Kherani E A , Paula E R De
Published: August 2023

Atmospheric gravity waves are known to be the source of medium-scale
traveling ionospheric disturbances (MSTIDs) in the upper atmosphere. In
recent studies, these gravity waves have mostly been linked to weather
convection activities from tropospheric altitudes during the daytime. In
this research work, we study the generation and dynamics of daytime
MSTIDs induced by tropospheric convections over the Brazilian sector.
Both observational and theoretical tools are employed to pursue these
objectives. Data from space and ground-based instruments such as a
network of GNSS receivers, digisonde, and meteorological satellites
(GOES Satellite) are analyzed to identify the driving source of
AGW-MSTIDs. The convectional-Atmosphere-Ionosphere-Coupled model
(CAI-CM) is adapted to incorporate the dynamics of convectively
generated AGWs and their coupling to the ionosphere. The model is used
to analyze the source of AGW as they propagate from the lower atmosphere
to the upper atmosphere and how MSTIDs are dependent on the sources that
generate them.
Climate energy balance models: two layers, orders, timescales, or regions?
Authors: Cael B. B. , Bloch-Johnson Jonah , Lutsko Nicholas
Published: August 2023

Climate energy balance models (EBMs) – simple energy-balance-based
models of climate change – are widely used. The simplest “linear” EBM
is deficient in capturing the behavior of complex climate models, so a
“two-layer” model with an additional degree of complexity, i.e. two
vertical layers, is typically used. Other additional degrees of
complexity are equally plausible as well, however, and different
approaches to add a degree complexity have not been compared
quantitatively. Here we compare four types of EBMs - two-layer,
order-two (temperature-dependent feedback), two-region (in space), and
two-timescale (fast and slow climate responses) - specifically, their
ability to capture historical temperature change and simulated
temperature changes in abrupt (4x) and gradual (1%-ramp) forcing
scenarios. The two-region model outperforms the others. The two-region
model’s best-fit parameters to historical temperatures are also more
physically plausible than the next-best-fitting model, the two-layer
model. We therefore conclude that the two-region model is the preferred
climate EBM.

Authors: Ozturk Gokhan , Tanyeri Burak , Oner Cengiz
Published: August 2023

This study compared the fuel consumption and exhaust emissions of a spark-ignition engine using a carburetor fuel system, an injection fuel system, and an ultrasonic fuel system. When using gasoline only, the ultrasonic fuel system showed a 31% decrease in fuel consumption compared to the carburetor system and a 15% decrease compared to the injection system. When adding 10% bioethanol to the gasoline, fuel consumption increased in all three systems, with the ultrasonic system showing the largest increase of 10%. Exhaust emissions were also measured, and the ultrasonic system showed a significant decrease in CO, HC, and NOx compared to the carburetor and injection systems, with the largest decrease in CO emissions. The addition of bioethanol to the fuel resulted in reducing exhaust emission values in all three systems, with the ultrasonic system showing the largest decrease in CO and HC emissions compared to the carburetor and injection systems, but with an increase in NOx emissions compared to the injection system. When comparing three fuel systems, it was observed that injection fuel systems have the highest CO2 values. Although the addition of alcohol to the fuel does not cause a significant change in CO2 emission values for injection and ultrasonic fuel systems, an increase is observed in the carburetor fuel system. Overall, the ultrasonic fuel system showed promising results for reducing fuel consumption and improving exhaust emissions.
Numerical evaluation of the heat transfer performance of water-cooled system for electric vehicle drive motor based on the field synergy principle
Authors: Zhang Jiacheng , Zhang Jiaming , Liu Zining
Published: August 2023

Thermal management of drive motors is a challenging design for transport electrification industries such as electric vehicles. Due to the high heat transfer performance, water-cooled system have become one of the technologies to meet the needs of these industries. Meeting the synergy between the heat transfer performance of the water-cooled system and the heat generated by the motor is key to taking advantage of the performance of drive motors. This study numerically evaluates and experimentally investigates the heat transfer performance of the electric vehicles drive motor water-cooled system based on field synergy principle, discussing the synergy between the temperature gradient field and velocity field of the water-cooled system under different cooling conditions, and the calculated results are consistent with the test results. By observing the interaction between the fluid vortexes and the main flow, the distribution pattern of the synergy angle in the cooling channels was determined. The results show that when the heat transfer capacity of the water-cooled system reaches its peak, the increase in Reynolds number instead leads to the increase in the average synergy angle of the whole field, which ultimately causes a deterioration of synergy between the velocity and temperature gradient fields.

Published: August 2023

The CaCO3 is being studied for its application in thermal energy storage. However, it has drawbacks of slow reaction rate during calcination and incomplete reversible carbonation which limit its use. In this paper, SiO2 has been studied as a dopant for CaCO3 to improve its cyclic performance. The CaCO3 samples were loaded with different concentrations of SiO2 and its effect on the thermal energy density of CaCO3 was determined. Afterwards, the effect of the dopant on the heat storage process of the synthesized composite along with kinetics of decarbonation reaction was investigated. Cyclic tests were performed to determine the reusability of the material. It was found that the addition of dopant helped to increase the rate of decarbonation reaction, thereby making the heat storage process more efficient as compared to pure CaCO3. The activation energy values are 255.9 kJ/mol, 280.1 kJ/mol, 244.9 kJ/mol, and 234.8 kJ/mol for 5%, 15%, 30%, and 0% doped SiO2 samples, respectively. Furthermore, thermal energy storage density increases when the amount of dopant decreases in the samples such as the 30% and 5% doped samples have gravimetric energy storage densities of 339.85 J/g and 759.24 J/g, respectively. It was observed that the large quantities (15% and 30%) of dopant had introduced a new phase of Ca3SiO5 during CaCO3 decomposition.

A feature of the implementation is the processing of the text, the analysis of words in the text and the formation of evaluations. A convolutional neural network implementation is designed to determine user authenticity based on facial photo analysis. implementation of fuzzy search algorithms – for processing text data of various volumes to analyze information about each user, form a certain user rating, compare this user with other users to promote further socialization of users whose interests coincide the most. When experimentally checking the accuracy of the developed system by determining the percentage of similarity of current users with the help of N-grams and their connections. Running these algorithms simultaneously is about 15% more accurate than the N-gram algorithm and about 10 % more efficient and accurate than the others algorithm. The operation of the algorithm for linear search of tags in the dictionary and the operation of the Noisy Channel algorithm using the BK-tree are also analyzed. Thanks to which it was possible to achieve significant advantages in the work algorithm, instead of a linear view of the search time, a logarithmic dependence was obtained. A system of synchronous and asynchronous methods also works. At first, the difference is not visible, but the more requests, the faster the system loads and tries to respond to them more by displaying from asynchronous methods.

Published: August 2023

The research in the domain of autonomous intelligent agent is the foreground of the introduction of artificial intelligence solution in all areas of economy. The intelligent autonomous systems combine the usage of pattern recognition, reasoning, decision making, conceptual modeling techniques and methods. The important part of intelligent agent implementation is to find the conceptualization which is suitable to the current problematic situation. Despite all progress around autonomous intelligent agents, humans are much more flexible and creative in making the right conceptualizations. They seamlessly adapt to the situation at hand and filter out all irrelevant details, using multiple perspectives and representations for the same objects. This research makes assumptions that every intelligent agent dynamically creates its own ontology used to interpret local knowledge. The mappings are established with this local ontology and the ontologies of other agents when needed, in order to share and reuse knowledge. In the article a formal model of problematic situation in the context of decision-making operation is presented. Models used in decision making and their relationships are described. In the second part of the article we analyze the process of conceptualization selection and arrive to the conclusion that this selection is done on multiple levels, starting from selecting the communicating agent with relevant domain of expertise, selecting and aligning ontologies of agents, selecting patterns and patterns languages which better correspond to the situation and lastly, selecting the relevant interpretations of concepts and relationships. In the last part of article, the problem of the selection of relevant knowledge provider is solved, using modified TOPSIS method. The proposed approach and directions of research will help to add flexibility to conceptual modeling of problematic situations by intelligent agents.

Workflow is a sequence of repeated and controlled steps aimed at completing a specific task or work. The urgency of the task of optimizing such works contributed to the development of methods and means of operations research to optimize such processes for the needs of various subject areas. Information technologies to support such workflow are workflow engines that enable faster automation, ensure compliance with norms and standards, formalize business processes, improve communication, etc. The workflow management systems are divided into the following categories: automation using robotics, intelligent integration platforms, intelligent business process management systems, open-source engines, the cloud-supported, as well as data flow processing systems. For a more detailed analysis, it is advisable to choose the following engines and services: built-in, cloud-oriented, and those to support both scenarios (jBPM, Camunda, Zeebe, Amazon Step Functions). It is appropriate to define evaluation criteria and compare such workflow automation systems to form further recommendations regarding their selection and application. Such criteria are development activity, stability and history of commercial use, versioning support, standards support, support for timers and asynchronous execution, support for human-oriented and manual tasks, integration with other solutions, monitoring and logging, scaling, cloud support, the possibility of scanning in private infrastructure, the presence of a visual interface, the convenience of local development and testing, open source code, the necessary programming for implementation and cost. A comparison of advantages and disadvantages can be used to decide on a workflow automation system.

The article develops an intelligent system of analysis and neural network forecasting of battery charge consumption for automated vehicles (AGVs). For this purpose, the types of AGV and the methods of effective forecasting of their battery charge consumption were analyzed. It is established that they are based on optimal robot control processes; application of technologies to increase capacity and extend service life. The data for the forecast was collected using the UAExpert OPC UA client, which allowed to convert the informative components of the data vector into a format suitable for further processing (csv). To eliminate outliers in the signals, a dispersion analysis of each parameter of AGV was carried out. Data for which the sigma value exceeded 1.5 were considered partialle lost and were replaced by a moving average of 12 points (the number of ANN inputs). For training, verification and testing of neural networks, parameters with high and medium positive correlation dependence were selected according to the Pearson correlation coefficient. Short-term and medium-term forecasting of battery charge consumption for AKTZ was carried out on the basis of ANN with deep learning, the model of which was tested in two modes: forecasting and prediction. The effectiveness of the developed system was investigated by testing it on the data obtained from Formica-1 AGV. The average absolute testing error was less than 1%. The highest value of the prediction error was less than 9 % when predicting such parameters as current position and X-coordinate, which are correlated with battery charge consumption for AGV. It has been established experimentally that the accuracy of the forecast of battery charge consumption for various types of AGV has been improved.

Published: August 2023

Military symbols play a key role in the command and control of military forces. By communicating information that meets basic requirements, situational awareness can be quickly achieved; by its graphical nature, it provides a common operating language that greatly facilitates interaction across cultural and linguistic barriers. With the advent of information technology, the need arose for rapidly recognized international standards that could then be taught to computers. The fusion of high standard air, sea and land symbols on APP-6 paper resulted in Mil-Std-2525 and NATO APP-6D. This standard applies to all NATO ground components that are directly or partially involved in C4I operations, system operations, systems development and training in the context of NATO ground component operations. When designing and developing signs, composing their components, factors such as the ability to easily recognize signs, their legibility in different lighting conditions on a diverse cartographic basis, in different sizes and types of electronic screens with different degrees of physical and intellectual fatigue should be taken into account. The conventional signs standard concentrates signs for use in modern multi-chromatic electronic systems. At the same time, all signs can be used in monochrome systems and for freehand decoration. Development of this software will allow creating comfortable conditions for performing such actions as: create and edit tactical graphics of military symbols; ensuring compliance with all standards regarding the conditions of standardization of APP-6D; performing secure transmission of characters between multiple users. The object of the research is an automatic generator of conventional symbols in the tactical military standard APP-6D. The subject of the research is software for automatic generation of tactical symbols in the APP-6D standard. The aim of the work is to develop software that will automatically generate tactical insignia in the APP-6D standard. A comparative analysis of various methods for the development of such systems for generating symbols has been carried out. The project was being developed and it does not have a single equivalent in the Ukrainian language. Also, there are not a single desktop implementation. The project can be part of the software used by the Ukrainian military.

Published: August 2023

Abdullahi Ahmed an-Na'im's Sharia Deconstruction is an alternative thought in sharia-based law reform. This thinking tries to reflect back on the dominant authority and interpretation in the Islamic legal tradition, by proposing an approach that is based on universal values such as fairness, fairness, and protection of human rights. An-Na'im argues that Islamic law must be seen as a social construction formed through a historical process and a particular context, and must be reconstructed in accordance with the demands of modern times. An-Na'im's sharia deconstruction approach also emphasizes the importance of freedom of religion and equality in society. He proposed peace between religion and the state, in which the state must treat neutrally and treat all citizens without taking sides or discriminating against certain religions. This thinking aims to create a legal system that is more inclusive and democratic, which involves the active participation of the community in determining appropriate laws and policies. Even though an-Na'im's deconstruction of sharia provides an alternative perspective in sharia-based legal reform, this view is still the subject of presumption among Islamic scholars and scholars. There are various viewpoints in interpreting and applying Islamic law, and the an-Na'im approach is only one of many existing approaches.

Background: The health system nationally and internationally, due to the recent advent of the Covid-19 pandemic, has faced a multitude of difficulties in its functioning. The pandemic posed a serious threat to
human health, causing rapid changes to the health systems and the health professionals, such as nursing staff, who were called upon to make every effort to respond to the difficulties by working intensively long hours. In these unprecedented circumstances, staff burnout has swelled and may pose a threat to patient safety.
Purpose: The purpose of this study is to investigate the role of nurses’ burnout and workload in predicting covid-19 patients’ length of stay.
Method: A total of 160 nurses of a General Hospital participated in the survey and 160 records were kept of 22 patients in the Intensive Care Unit (ICU) Covid-19. The Maslach questionnaire (Maslach Burnout Inventory (MBI)) was used as a study tool to measure burnout, the Nursing Activity Score (NAS) for nursing workload and the duration of hospitalization for Covid-19 patients were taken from hospital records. Multiple regression analysis was performed with the stepwise selection method, in order to be able to determine the factors that affect the patients’ length of stay.
Results: Nurses’ burnout in ICU Covid-19 was found to be high as well as their workload. However, only the nursing workload (β =, 452 t = 2,124, p = 0,35) was associated with a longer patients’ length of stay in the ICU
(F (1,158) = 4,512, p <, 001) and not the dimensions of burnout.
Conclusions: The current pandemic pointed out the existing gaps in the health system. Nurses are unable to influence the uncontrollable course of Covid-19 disease, which has hampered their daily work and mental
health and their workload has an impact on patient safety.

Introduction: Addiction is a condition in which a person acquires a habit which affects the behavior and psyche and makes it difficult to confront with. When we talk about internet addiction, we are referring to problematic
internet use that is associated with significant social, psychological and occupational dysfunction.
Purpose: To identify whether the citizens of Patras, in the current period, are addicted to the internet.
Materials-method: Young’s questionnaire which containing 20 questions was used. The sample (n=527) were citizens from Patras. The statistical analysis was performed using the SPSS 25.
Results: Participants had a score from 10-73 (mean, 31.52) which considered “average online user” who has control over use. More precisely, 30.4% of the sample answered that it often happens to them to stay online longer than intended while 53.1% of the sample prefers fun with friends instead of the excitement to internet. Also, 52.6% answered that they have not tried to hide their time spent online and 33% believed that they do not create new relationships through Internet. It is important to mention that 62.8% of the participants state that most people feel depressed, moody or nervous when they are offline and they do not overcome these feeling even if they are online. Furthermore, participants who lived in an urban area had a higher score (r = .087, p<0.05) than those who lived in rural and island areas. Finally, participants with the highest level of education (University degree) had a higher score (r = -.088, p<0.05) than the participants with middle school and high school education.
Conclusions: Internet addiction seems to have appeared in our country as well, but participants have control over usage. The state needs to ensure that sufficient and correct information needs to be delivered to citizens
so that the phenomenon of internet addiction can be treated in time and further negative consequences for the population can be avoided.
Liebesblicke im Spiegel. Zu Narcissus und Hermaphroditus in Ovids Metamorphosen
Authors: Beer Beate
Published: August 2023

Ovids Metamorphosen schildern Liebeserfahrungen oft in der Reaktionsfolge von Blick und Begehren. In den Erzählungen über Narcissus (met. 3,339–510) und Hermaphroditus (met. 4,274–388) werden sie durch das Medium des Spiegels intensiviert. Der spiegelnde Teich wirft Narcissus und Salmacis als Figuren, die begehren, ein Bild entgegen. Hermaphroditus, der ohne Begehren gezeigt wird, blickt dagegen durch den Spiegel hindurch auf den Grund des Teiches. Der komparatistische Zugang zeigt, wie Liebe und Begehren durch die unterschiedliche Wirkung des Spiegels als Auseinandersetzung mit Alterität, die Narcissus an sich selbst erfährt, und Identität, die Hermaphroditus vor der Liebeserfahrung am Teich fremd ist, entworfen werden. Das Konzept von Alterität und Identität macht beide Liebeserfahrungen als bacchische Erfahrungen beschreib- und aufeinander beziehbar. Es erhellt ausserdem Hermaphroditus’ äusserlich wenig fassbare Verwandlung als Entdeckung seiner Identität.
