Published: November 2023

Abstract. In order to facilitate offshore wind farm tenders, Deutscher Wetterdienst (DWD, Germany's national meteorological service) provides reanalysis data and quality assessments to Bundesamt für Seeschifffahrt und Hydrographie (BSH, Federal Maritime and Hydrographic Agency). The regional reanalysis COSMO-REA6 is used besides the global reanalysis ERA5. New reanalyses and derived products getting available are (i) the regional reanalysis CERRA (C3S), (ii) COSMO-R6G2, a successor of COSMO-REA6 which is currently produced by DWD and (iii) HoKliSim-De, a convection-permitting climate simulation for Germany with COSMO-CLM as a regional downscaling of ERA5. In the present study, the quality of the different data sets for offshore wind energy application is compared using in-situ measurements of the wind speed and wind direction from the top anemometer and vane of the FINO1 research platform and satellite-based data of the near-surface wind speed from the Copernicus Marine Environment Monitoring Service (CMEMS) and the EUMETSAT Satellite Application Facility on Climate Monitoring (CM SAF). Evaluation at FINO1 focuses on the time period prior to the installation of nearby wind farms to avoid wake effects. COSMO-REA6, CERRA and HoKliSim-De show only small biases and resemble the observed distribution of the wind speed at FINO1 whereas ERA5 shows slightly lower values of the wind speed at 100 m. All model-based products tend to slightly underestimate the occurrence of south-westerly wind directions and overestimate wind directions from West to Northwest. Smallest directional biases are analysed for COSMO-REA6. Analysis of the windstorm CHRISTIAN suggests that ensemble information is required for the representation of individual extreme events. Evaluation of the near-surface wind speed using satellite-based data is performed for an area around the German Exclusive Economic Zone (EEZ) of the North Sea. The median bias of ERA5 and COSMO-REA6 is close to zero. CERRA shows a systematic overestimation of the near-surface wind speed compared to the satellite-based reference datasets. By contrast, a slight underestimation is analysed for HoKliSim-De. The bias distribution analysed for a first simulation stream of COSMO-R6G2 is similar to COSMO-REA6 which provides initial indication for the applicability of the new product.
Estimating the uncertainty of sea-ice area and sea-ice extent from satellite retrievals
Authors: Wernecke Andreas , Notz Dirk , Kern Stefan , Lavergne Thomas
Published: November 2023

Abstract. The net Arctic sea-ice area (SIA) can be estimated from the sea-ice concentration (SIC) by passive microwave measurements from satellites. To be a truly useful metric, for example of the sensitivity of the Arctic sea-ice cover to global warming, we need, however, reliable estimates of its uncertainty. Here we retrieve this uncertainty by taking into account the spatial and temporal error correlations  of the underlying local sea ice concentration products. We find that the observational uncertainties of both sea-ice area and sea-ice extent (SIE) in 2015 are about 300 000 km2 for daily and weekly estimates and 160 000 km2 for monthly estimates. This daily uncertainty corresponds to about seven percent of the 2015 sea-ice minimum and is about half of the spread in estimated sea-ice area from different passive microwave SIC products. This shows that random SIC errors play a role in SIA uncertainties comparable to inter-SIC-product biases. We further show that the September SIA, which is traditionally the month with least Arctic sea ice, has declined by 105 000 km2 a-1 ± 9 000 km2 a-1 for the period from 2002 to 2017. This is the first estimate of a SIA trend with an explicit representation of temporal error correlations.

Published: November 2023

Abstract. Atmospheric precipitable water vapor (PWV) is a very important meteorological factor for weather forecasting and climate change monitoring. GNSS observation and ERA5 reanalysis for the period of 2010–2022 are used to analyse the overall and seasonal distribution and interdecadal trend of PWV in North America. The results indicate that GNSS and ERA5 are in good agreement between the distribution and interdecadal trend of PWV. The overall PWV change from 2010 to 2022 shows an obvious upward trend. The mean PWV is less than 20 mm in most regions of North America except for the Southeast where mean PWV is more than 30 mm. The change trend and correlation of PWV and temperature in North America from 1940 to 2022 based on ERA5 reanalysis data are analysed. The results show that the PWV increases more significantly with the interdecadal trend of 0.17 mm decade-1. The results illustrate that there is a significant correlation between PWV and temperature with the correlation coefficient of 0.96, and that there are some differences between the actual increase and ideal increase of water vapor content derived from Clausius-Clapeyron equation for every 1 K increase in North America. In addition, the results also show a significant increase of PWV during strong El Nino events and a significant decrease of PWV during strong La Nino events, thereby indicating that El Nino and La Nino events have an important influence on the change of PWV in North America.

Published: November 2023

The low treatment rate, low treatment success rate and high mortality rate of patients with pre-extensively drug-resistant tuberculosis (pre-XDR-TB) and extensively drug-resistant TB (XDR-TB) need serious attention. The aim of this study was to describe the profiles of patients with pre-XDR-TB and XDR-TB cases and to determine associated risk factors of their incidence in Indonesia. A retrospective case-control study was conducted at H. Adam Malik General Hospital in Medan, North Sumatra of which all sensitive-drug TB (SD-TB), pre-XDR-TB, and XDR-TB patients aged 18 years or older treated between October 2019 to June 2022 were included. Chi-squared test or Kruskal Wallis test and multiple logistic regression were used to determine the risk factors associated with pre-XDR-TB and XDR-TB incidence. A total 16 patients of case group (15 pre-XDR-TB and one XDR-TB) and 116 SD-TB patients (control group) were included in the final analysis. Out of total patients within case group, 62.5% were male, 43.8% aged between 56–65 years, 62.5% graduated from high school or equivalent, and 25% were unemployed. The majority of patients had no comorbid (62.5%), had history of anti-TB treatment (93.8%), and had secondary resistance (93.8%). Multivariate analysis indicated that age (OR: 10.01; 95%CI: 1.49–66.91, p=0.018) and previous history of anti-TB treatment (OR: 216.25; 95%CI: 18.62–2511.60, p<0.001) were significantly associated with incidence of pre-XDR-TB and XDR-TB. This study highlights that having previous history of anti-TB treatment and older age are the predictors of the incidence of pre-XDR-TB and XDR-TB.

Published: November 2023

Esta investigación de tesis presenta los resultados obtenidos durante los estudios geoarqueológicos realizados en la localidad Touro Passo, municipio de Uruguaiana, Brasil. Alli se reubicaron los sitios paleoindios estudiados por el equipo del PRONAPA Programa Nacional de Investigaciones Arqueológicas en las décadas de 1960 y 1970 y han sido reconocidos otros con excelente potencial de estudio. Los sitios arqueológicos están situados en las planicies aluviales del Río Uruguay y del Arroyo Touro Passo y corresponden a la transición Pleistoceno tardío-Holoceno temprano. El enfoque geoarqueológico permitió la comprensión de la secuencia estratigráfica y los procesos de formación y perturbación posdepositacional de los sitios arqueológicos en ambiente fluvial. Fueron realizadas excavaciones arqueológicas, sondeos, relevamiento de perfiles-estratigráficos, correlaciones de secuencias y fechados numéricos. Se registró la dispersión de los artefactos en superficie y en las cárvavas de erosión, y se realizó, un estudio de tafonomía lítica. Se analizaron 4 sitios paleoindios situados en la Formación Touro Passo: Barranca Grande, RS-I-66:Milton Almeida, RS-I-69: Laranjito y Casualidade. En lo sitio Barranca Grande se recuperaron fragmentos de carbón asociados con artefactos líticos que proporcionaron una edad de ca. 9900 años C AP. Por debajo de estos se obtuvo una muestra de troncos carbonizados con una edad de ca.10.500 años C AP. En los sitios RS-I-69: Laranjito y Casualidade, debido a la ausencia de carbones arqueológicos, se tomaron muestras para dataciones por luminiscencia estimulada ópticamente - OSL. La incorporación de una perspectiva geoarqueológica, los análisis tecno-tipológicos y tafonómicos. Las nuevas cronologías a nivel local y la comparación regional con sitios temprano en el Uruguay han posibilitado ampliar el conocimiento y contribuir con las discusiones sobre el proceso de ocupación humana inicial de esta parte de Sudamérica.
Morphisms between Aristotelian Diagrams
Authors: Klerck Alexander De
Published: November 2023

In logical geometry, Aristotelian diagrams are studied in a precise and systematic way. Although there has recently been a good amount of progress in logical geometry, it is still unknown which underlying mathematical framework is best suited for formalizing the study of these diagrams. Hence, in this paper, the main aim is to formulate such a framework, using the powerful language of category theory. We build multiple categories, which all have Aristotelian diagrams as their objects, while having different kinds of morphisms between these diagrams.

The categories developed here are assessed according to their ability to generalize previous work from logical geometry as well as their interesting category-theoretical properties. According to these evaluations, the most promising category has as its morphisms those functions on fragments that increase in informativity on both the opposition and implication relations. Focusing on this category can significantly increase the effectiveness of further research in logical geometry.

Authors: Merdas Hussam , Mousa Ayad
Published: November 2023

Iraq is considered one of the first countries in the world to export Dates of all kinds. This sector at present needs support and serious work to improve sales to provide the country's economy with more revenues. This study proposes building an integrated artificial intelligence model that predicts the quantities of Dates that Iraq will produce in the coming years based on previous data and based on two main points: The first point is to make a comparison between three different food datasets with a different correlation between their features, as the first dataset is of high correlation, the second is of medium correlation, and the third is of weak correlation. The second point is to apply twelve Machine Learning algorithms and evaluate their results to obtain the best three algorithms. The model was applied to predict the quantities of Dates that Iraq will produce for the next five years. The proposed three algorithms were used and gave the following results: (Gradient Boosting: 99.51, Random Forest: 97.05, and Bagging Regressor: 98.54). This study constitutes a starting point for future studies in terms of the process of choosing the datasets, as well as the machine learning technique.

Authors: Fernandes Wania Ribeiro , De Lima Maisa Lemos
Published: November 2023

The study aimed to describe how the process of inclusion of people with disabilities in the settlement school has occurred. The debate is articulated with the following problematization: how has the inclusion of people with disabilities occurred in settlement schools? To this end, we carried out bibliographic and documentary research to meet specific objectives: a) present the concept of equity in light of the Universal Declaration of Human Rights and public inclusion policies; b) discuss the complexity of the inclusion process in a settlement school; identify the facilitating and hindering factors in implementing school inclusion for students with disabilities. When presenting the context of inclusion in settlements, we saw that these discursive practices introduced by inclusion policies constitute strategies based on Foucault's concept of biopolitics and governmentality, thinking about diversity and difference from the perspective of the State.

Published: November 2023

Every day, our workplace is influenced by the presence of emotions, which form an essential part of our biological makeup. These emotions accompany us into the professional setting each morning, shaping our actions and reactions. The different dimensions of EQ, as well as its consequences on workers and their organisations, are now the focus of research. EQ boosts efficiency and effectiveness in the workplace. It has a big impact on the results an employee achieves and the rapport he or she has with coworkers. Leaders and managers in IT have found work-life balance to be a difficult problem, and studies have taken notice. This study's literature evaluation on emotional intelligence and work-life balance has enlightened the researcher on several issues. It also gives guidance in planning the current research. The researcher felt compelled to conduct the current study after reviewing the existing literature and identifying the void. There were 375 IT workers in Bangalore, India, chosen at random. Both men and women working in IT were included in the sample. To determine how many people from each of the three categories of management level would participate in the survey, a judgmental sampling method was used. This inquiry will spark a series of thoughtful and fruitful conversations on leadership in the workplace. The findings of this research show that retail businesses may achieve greater profitability and gain a competitive edge by emphasising both emotional intelligence and work-life balance.

Research on Psychological Adaptation Strategies of Employees in Enterprise Change Management
Authors: Li Yutong
Published: November 2023

Due to the impact of economic globalization and market internationalization, many enterprises are facing increasingly serious environmental problems. Only by means of transformation can enterprises continuously adapt to the external environment and seek better survival and development. Major changes in enterprises may cause core employees to be forced to adapt to new tasks and environments, or they may become potential losers due to changes in the pattern of benefits brought about by the changes. Therefore, the uncertainty of enterprise change is a risk for core employees, and facing risks will inevitably lead to psychological confusion and affect the development of enterprise work. For a long time in the past, domestic enterprises did not have a sufficient understanding of the importance of employee psychological health, and generally did not pay enough attention to counseling employees on psychological issues. This has led to many problems in enterprise management, not only causing harm to employee psychology, but also being very detrimental to the healthy development of the enterprise. Especially during the period of social transformation, the changes and challenges faced by Chinese enterprises are unprecedented and complex. Once interpersonal relationships are in good condition, the mental state of employees and the performance of the enterprise will be problematic. Based on this, this article studies employee psychological adaptation strategies in enterprise change management.

The essential sun: Its past, present, and future
Authors: Ke Jiayi
Published: November 2023

The sun provides warmth and light essential to human life, making it important to investigate its formation, current state, and future evolution. This article includes information on the formation of the sun and an overview of its current state. The sun formed about 4.6 billion years ago from a giant nebula in one of the spiral arms of the Milky Way galaxy, after which the solar system formed from. As for its structure, the sun consists of six layers: core, radiative zone, convection zone, photosphere, chromosphere, and corona. The sun is a main sequence star and is situated at a considerable distance from the earth. This distance is calculated using the parallax method, which involves measuring the parallax angle and applying trigonometry. Another approach to determine the distance is by utilizing Kepler's Third Law. The sun continually undergoes fusion in its core due to specific conditions that allow for fusion reactions to occur, including extremely high temperatures, high density, and a suitable containment vessel. In the future, the sun will evolve into a red giant star before ultimately becoming a white dwarf star. Eventually, the earth will be engulfed by the sun as the sun evolves.
A criterion of periodic point stability based on Lyapunov exponent
Authors: Yang Zhenyu
Published: November 2023

The logistics equation is the most classical model of population growth. Influenced by external environmental factors and growth inertia, the total population is in a state of periodic equilibrium. so, studying the stability of the periodic solution of the logistics equation is an important issue. If the logistics equation is considered as a function, the general method to judge the stability of the periodic point is to bring in the derivative of the function after iterating n times to take the value. The Lyapunov exponent is originally an important method used to judge the stability of dynamical systems. If the logistics map is considered as a discrete dynamical system, applying the Lyapunov exponent to the determination of the periodic solution will largely reduce the computational effort.
Lobachevsky's formula and its applications to several definite integrals
Authors: Wang Yu-Hsiang
Published: November 2023

The definite integral is a fundamental concept in calculus that has many applications in various fields such as physics, engineering, and economics. However, integration can be difficult and requires a variety of skills such as substitutions and partial integration. In this paper, Lobachevskys formula is explored, which provides a new way to evaluate definite integrals. It should be noted that Lobachevskys formula can only be applied in specific cases where the integrand is even and -periodic. However, it is demonstrated to be an effective method in these cases. In this paper, the proof of the theorem is given, and a variety of examples are solved by virtue of this method. Hence, this paper may serve as a reference for relevant research in the field of calculus and provide insights into the applications of Lobachevskys formula.
Baryonic impacts on dark matter at different scales
Authors: Kong Chuiyang
Published: November 2023

Contemporarily, dark matter remains a mysterious part of the universe where no exact model has been confirmed experimentally. Nevertheless, various studies have discussed possible impacts on dark matter based on theoretical framework and numerical simulations in recent years. In this study, it aims to find baryonic impacts on dark matter by comparing dark matter distribution in dark matter only simulations and hydrodynamic simulations on different scales (cosmic web and dark matter halos). To be specific, some previous results are compared between several studies analysing baryonic impacts, mainly focusing on the mass fraction and volume fraction of cosmic web, halo shape, halos orbital properties, phase space density, some physical processes related to baryons, etc. Additionally, the state-of-art hydrodynamic simulations and dark matter only simulations are introduced briefly as a basic knowledge. Overall, these results shed light on guiding further exploration of dark matter behaviours on different scales under the impact of baryons.
Exploring the galactic center through gravitational microlensing: Prospects and possibilities with next-generation infrared telescopes
Authors: Qiu Zijian (Max) , Jiang Peng
Published: November 2023

We aim to present a solution to the lack of observational support to our theoretical model of the Supermassive Black Hole (SMBH) and the Galactic Center (GC). To do so, we revisit the abundance of microlensing events produced by the SMBH at the GC as a fixed lens, based on the methods given by Alexander & Loeb 2001 (AL01). By applying updated observational constraints for the distribution of stars within a few arcseconds of the SMBH, we estimate the number of lensing events of distant background sources by the SMBH alone or by it and secondary stellar lenses that lie within the GC. We find our new results to be generally consistent with AL01. We predict that in any snapshot of the central ~1 region taken with a modern detection threshold of 27-28 mag, ~10 microlensed background sources will be amplified for more than 500% in brightness. As more potential microlensing events in the GC are being identified by K-band surveys with a much higher precision than previous speckled observations, we would be able to test our predictions and offer validations on the theoretical models of GC and the SMBH.
The Boltzmann distribution in gravity field
Authors: Hao Junyao
Published: November 2023

The air is comprised of innumerable particles. In the atmosphere, the particles are mostly gas molecules, including nitrogen, oxygen, and hydrogen, extending in the air in a gravitational field caused by Earth. With thermal statistics, there are methods to calculate and observe some microscopic properties of this group of particles. This essay aims to disclose the density distribution of gas particles in the air from different altitudes and at different speeds. All the calculations have proceeded on the approximately ideal circumstance with some corrections. The calculation and observation method is based on ideal gas law and rudimentary Boltzmann distribution using knowledge of thermal dynamics and thermal statistics. At the end of the main body of this essay, the final formula is given with graphs created in Matlab providing more ocular illustrations. These parameters are mostly composed of physical fundamental constants and do not require information from a database.

Authors: Shi Junzhe
Published: November 2023

This report aims to determine the probability range of the number of collisions under the optimum collision condition. The optimum condition was obtained by determining the average values of the given variables in the Glauber Model. Graphs of against eccentricity 1, 2, and 3 (Ecc1, 2, and 3) were plotted respectively according to the data generated from the Glauber Model Simulation in CERN ROOT. Then, the optimum average value was plotted as a vertical line on the graph to determine the range of . The probability ratio of an optimum collision versus maximum probability in an event was concluded to fall in a certain range of 0.30 0.07, and this range is verified to be a stable range that could be used for prediction of optimum collision numbers in future nuclei collision experiment. This probability ratio can be used to predict the optimum collision with only provided.
The study the angle of attack and lift magnitude of a wing using COMSOL software
Authors: Chen Runpeng , Zhao Yongqi
Published: November 2023

Angle of attack (A.O.A.) is defined as the angle at which the chord of an aircrafts wing meets the relative wind. At low angles of attack, the wing could just create a small amount of lift, and it also experience a small amount of drag. As the A.O.A. increases, both lift and drag will increase. However, when the wing reaches a critical angle of attack, the lift it could produce will quickly decrease, since the separation of the air flow and the wing surface. The objective of this study is to find the relationship between the angle of attack and the lift coefficient(which is proportional to the lift it could produce) of the wing. And as a conclusion, we find that the A.O.A. increase, the lift coefficient will also increase, and if the inlet velocity, the wings surface area and the velocity remains constant, when the lift coefficient increase, the lift will also increase.
Multiclass classification of body performance based on LightGBM
Authors: Lu Ziniu
Published: November 2023

The fitness industry is transforming due to the Covid-19 pandemic, and the demand for personal training is growing. The absence of a standardized and accurate body performance measuring framework can lead to misjudgement of the clients physical condition and risks of injuries or dissatisfaction with the service. This paper applies LightGBM on a dataset containing 13393 instances from Kaggle.com for body performance level classification analysis. The model is built with 12 predictors, such as age, gender, body fat percentage, sit and bend forward distance, and a target variable class, representing the body performance level of a person. The accuracy score obtained from the confusion matrix is used as the key metric for model performance. A grid search on hyperparameters including regularization term, maximum number of leaves, and maximum depth of the tree is conducted for parameter tuning. The outcome of the model gives insight into the importance of various features to body performance and helps fitness trainers to better understand their clients physical conditions. Results of this research show that sit and bend forward distance and sit ups counts are the most important factors of body performance. The quality of the classifier solution makes it a useful decision aid for personal trainers to access their clients physical condition.

Does gravitational time dilation influence the propagation of the change of gravitational field?
Authors: Wang Xinghong
Published: November 2023

This article uses thought experiments and strict logical deductions to discuss the propagation the change of gravity field and find that all current gravity fields are generated some time before and they are not static but are constantly propagating. If there is a change of the gravity field of a celestial body, it takes time for this change to propagate before interacting with this another celestial body. However, for a binary black hole system, the positions of the two black holes constantly changes relative to each other, resulting in changes of the gravity fields of both black holes, and, it also takes time for the change of gravity field of one black hole to reach the other black hole. If gravitational time dilation governs, it takes forever for the change of the gravity field of one black hole to propagate across the event horizon of the other black hole and interact gravitationally with it. If so, one black hole will never be able to respond to the change of the location of the other black hole. This is impossible. Thus, gravitational time dilation should not have the same influence upon the propagation of the change of gravity field as it has on light.
