Abstract. We introduce an innovative 2-week educational block course held at the University of Bonn during the 2023 winter semester, focusing on Cloud Model 1 (CM1) and its convection-resolving capabilities. During the course, participants gained essential skills in setting up and customizing CM1 simulations on a high-performance computing cluster while gaining insights into moist-convection dynamics. An additional introduction to three-dimensional visualization software allowed the participants to transform numerical data into compelling visualizations, deepening their insights into cloud dynamics. The participants applied their gained knowledge in research projects of their own choice that will be presented here and in the Supplement.
Examining Urban-Rural Public Service Equalization and Common Prosperity in China: A Data-Driven Study on Regional Disparity
Authors: Hao Liang  
Published: May 2024

Achieving equal access to basic public services between urban and rural areas in China has become an important pathway to eliminating inequality, improving national welfare, and ultimately achieving common prosperity. Through data analysis and a data-driven approach, it is possible to better guide future policy formulation and implementation to help China achieve its goal of inclusive growth. This research endeavors to examine the interrelations between the discrepancies in basic public services provision in urban and rural areas, establishing a comprehensive evaluation indicator framework, while delving into the intricate dynamics between such service equalization and the attainment of common prosperity. Moreover, it aims to uncover the varying degrees of regional disparities witnessed during the journey to common prosperity in different parts of China, thereby providing valuable insights and references for nations and regions striving to enhance social equality. This study focused on the 31 provincial-level administrative regions of China(excluding the regions of Hong Kong, Macau, and Taiwan) The research methodology entails employing the entropy weight method to determine the weights of evaluation indicators, supplemented by a coupling coordination model to analyze the level of harmonization between urban and rural areas. Furthermore, the Dagum Gini coefficient method and kernel density estimation were utilized for an in-depth exploration of the distribution and disparities observed in regional coordination. The findings of this study reveal that between 2012 and 2021, the disparities in the equalization of basic public services between China’s urban and rural areas witnessed a progressive widening, despite modest improvements in the overall level of common prosperity. The prevailing pattern observed can be summarized as “high coupling, low coordination”. Notably, these disparities are particularly conspicuous in the western regions of the country. Additionally, this research identifies the imbalanced development of basic public service equalization between urban and rural areas as the primary cause for the observed low level of coordination. This study emphasized the intrinsic nexus and coordinated interplay existing between the equalization of urban and rural public services and the achievement of common prosperity. To foster enhanced coordination between urban and rural areas, it is imperative to prioritize the implementation of policies that promote the amalgamation of urban and rural realms, while concurrently striking a harmonious balance in the pursuit of multi-dimensional objectives. Furthermore, region-specific policies need to be formulated, with particular attention to addressing the disparities in coordination and the polarization issues prevalent in the western regions, ensuring the effectiveness and precision of these measures.
Patch-based Reversible Steganography for Secured Communication over Wireless Channels
Authors: Mukund D. Maid  
Published: May 2024

Securing the perceptual quality of the cover image (CI) and acquiring higher security for hidden information in stego images (STIs) are two sides of the same coin. There is always a trade-off between perceptual quality and level of security when secret bits (SBs) of the secret image (SI) are embedded in a CI. Non-reversible techniques are adopted where a higher level of security is required as in communication, while reversible schemes are preferred to maintain the visual quality of the CI. This article proposes a novel Patch-Based LSB Embedding (LSBE) Data Hiding (PB-LSB-EDH) scheme that provides better security to SBs and maintains stego quality. The scheme embeds a secret byte in a 3x3 patch of the CI. The starting byte in the neighborhood where the SBs are hidden is computed from the center pixels of the 3x3 patch window and continues to embed pixels clockwise. The PB-LSB-DH scheme is highly immune to external noise or attacks when the intensity value of the center pixels is equal to or greater than 12 since the starting index of bit embedding is computed using a natural logarithm. Experimental analysis of four different CIs and SIs showed that the proposed PB-LSB-DH scheme maintains the better perceptual quality of the CI and a higher peak signal-to-noise ratio (PSNR) above 50.
Design and Performance Evaluation of Fuzzy Controller based Energy Storage Enabled Statcom for Electrical Distribution Network
Authors: Srinu Bhukya  
Published: May 2024

In order to fulfill the demand for power, the production of locally accessible resources, such as solar and wind energy, has increased dramatically during the past ten years. Their integration into the distribution of electrical network (EDN) has affected the operation of the network. Variations in the real power flow and an increase in reactive power demand have impacted the EDN voltage/frequency profiles and distribution transformer strain. Hence to improve the voltage regulation and reduce the active power fluctuations, there is a need for a system network of electrical distribution (EDN). It has the ability to support both reactive and active power. Thus, the energy storage device with STATCOM is introduced i.e. an energy storage device linked to Statcom (EsSt) has been proposed in this paper. The Common Coupling Point (CCP) voltage can be adjusted by energy storage connected to Statcom (EsSt) to satisfy the amount of power required actively at EDN. The EsSt has an integrated battery storage system and may be controlled using a voltage source converter by employing the proper control strategy to deliver the necessary energy support and VAR compensation. The voltage at the dc-link has been integrated using DC-DC converter based half bridge. The use of conventional PI controllers provides poor transient response. To improve the transient performance, It is suggested that a fuzzy logic controller be used in place of the PI controller. Analysis of comparison using MATLAB. The rule-based fuzzy logic controller performs better than the PI controller, according to the Simulink environment.

Published: May 2024

Objectives: Healthcare analytics requires classifying diabetic patient datasets for quicker diagnosis and personalized treatment. This study used SVM, Decision Trees, KNN, ANN, and Logistic Regression to predict type 1 and 2 diabetes. Our detailed performance research shows these algorithms' utility in handling diabetic patient data's complexity.
Methods: We compare SVM, Decision Trees, KNN, ANN, and Logistic Regression for diabetes patient dataset classification. While each approach has pros and cons, ANN and logistic regression are promising clinical possibilities. Diagnoses, proactive therapies, and diabetes patient outcomes increase with these breakthroughs.
Results: SVM has 84.3% accuracy in type 1 and type 2 diabetics. SVM recognized complicated dataset patterns with great accuracy and recall. Decision trees were more interpretable and could record diverse choice limits, with accuracy rates of 86.15% for both types. With 90.6% accuracy, KNN predicted type 1 diabetes well. KNN was ideal for complex datasets because to its greater accuracy and recall using data point similarities. ANN and Logistic Regression had the highest accuracy for type 1 and type 2 diabetes patients at 96.1% and 97%, respectively.
Novelty: Layered ANN and logistic regression identified complicated dataset relationships with accuracy, recall, and F1 scores exceeding 0.94. ANN with logistic regression may change diabetes patient classification with unequaled prediction power and accuracy.
An Efficient Cross-Domain Recommendation System Based on Clustering Approach and User-Score
Authors: Shwetal Raipure  
Published: May 2024

Growing consumers and online commercial products have put a great challenge on Recommender systems. Abundant browsing and online shopping across the world have provided immense opportunities to E-commercial giants to effectively learn the behaviour and attract users. However, due to the variety of available products and distinct consumers, crucial issues of data sparsity and cold start problems have been introduced. Single-domain recommendation systems are unable to handle such issues and research has been concentrated on developing more sophisticated cross-domain recommendation systems. Concerning other systems, non-overlapping domains form the most difficult part to solve using the cross-domain approach. This article focuses on partially overlapping domains and suggests a simple and efficient approach based on mapping users' interests by clustering books and movies. The cluster information from the auxiliary domain is transferred to the target domain using the user score and mapped properly to recommend books. The user and item scores in both domains are computed using the transfer frequency-inverse document frequency approach. The proposed recommender system offers low computational complexity and requires less time.

Existence of a periodic solution for a state-dependent delay differential equation with a singular perturbation
Authors: Nehari Mohamed 
Published: May 2024

The idea of this article came from the works dones by Khung and Smith on the one hand in [2] for and Arino and Al in [1] for on the other hand, to proves the existence of a slowly oxillating preriodic solution by the fixed point theorem of Picard. I proposed the following question: Do the result remain valid if 1 ? by the same method with using the homotopy well defined link between the application of Khung and Smith and the application of Arino and and indeed, I came to prove existence of a slowly oxillating preriodic solution by the fixed point theorem of Picard, therefore the result obtained in this work is generalization of two special cases. A State-dependent Delay Differential equation play important role in recent years to modeling of several phenomenon, in dynamics of populations, in biology and even in the social life for example: When we take our driving test, we learn that the reaction time of our nervous system when driving is of the order of a few seconds, and that we must take care to maintain a sufficient distance between two cars following each other, from this example, we notice that the delay can be useful. Although this work has added a new addition to the scientific field which is a generalization and linking between two special cases, it remains somewhat limited because it takes special case of Arino and Al. Therefore in the futur, we are thinking about a new work that takes into account the general case of Arino and .

As cirurgias parciais ou totais por lesão em menisco, seja por sutura ou refixação, são comumente aplicadas nos casos de ruptura do menisco do joelho. Além disso, a meniscectomia parcial é realizada com maior frequência, mas resulta em déficits funcionais significativos, principalmente na diminuição da força muscular dos extensores do joelho, dos quais influenciam na estabilidade adequada do joelho e distribuição normal de cargas entre as superfícies da articulação. Logo, um programa de fisioterapia antes, durante e após a identificação da lesão em menisco é fator importante para designar possíveis tratamentos, seja ele conservador ou invasivo. Dessa forma, com o crescente corpo de literatura sobre a reabilitação após meniscectomia de joelhos, e os aspectos gerais dessa cirurgia, foi possível a realização de uma revisão integrativa de literatura em diversas bases de dados indexadas reconhecidas por sua confiabilidade e relevância na área médica, com seleção e análise criteriosa dos artigos, a fim de revisar e analisar as evidências atuais sobre as características gerais da meniscectomia e a reabilitação na cirurgia de joelho, e possível prevenção à cirurgia de menisco. Nesta revisão foi identificado que a tomada de decisão quanto a melhor linha de tratamento em doenças degenerativas de joelho e ou rupturas; deve ser investigada com grande atenção pela equipe de médicos e fisioterapeutas para a escolha do melhor tratamento, evitando assim uma maior gama de complicações e efeitos deletérios quanto a estrutura articular do joelho. Portanto, o tratamento em conjunto com a fisioterapia na reabilitação de cirurgias no joelho, como foco em meniscectomia do joelho, é de extrema importância quando levando em consideração a necessidade de tratamento conservador e preventivo.

As deformidades dento-esqueléticas (DDE) são definidas como desproporções dentárias e faciais decorrentes de alterações de crescimento dos ossos da face. Podem levar à diminuição do espaço da via aérea superior (VAS), contribuindo para o desenvolvimento de distúrbios respiratórios graves, como a síndrome da apneia obstrutiva do sono (SAOS). Este estudo avalia mudanças no espaço aéreo faríngeo dos pacientes portadores da SAOS que foram submetidos a cirurgia de avanço bimaxilar para correção das DDE, a fim de detectar possível aumento da VAS como tratamento cirúrgico definitivo da SAOS. Para a avaliação do espaço aéreo utilizou-se um novo protocolo de delimitação da VAS, onde foram avaliadas tomografias computadorizadas (TC) no pré e pós-operatório da cirurgia ortognática de nove pacientes com perfil facial Classe II que apresentavam a SAOS associada, a fim de mensurar o diâmetro da VAS e o novo posicionamento do osso hioide. Uma vez coletados os valores mensurados, estes foram submetidos ao tratamento estatístico, através do programa SPSS (24.0). Aplicou-se o teste de normalidade de Shapiro-Wilk para averiguar a distribuição dos dados. E o teste t emparelhado para a comparação entre as mensurações no pré e pós-operatório. Observou-se um aumento estatisticamente significativo da VAS no corte sagital (média 0,35; p=0,001) e no corte axial (média 0,51; p=0,001). Já em relação às mudanças de posição do osso hióide, não houve diferenças estatisticamente significativas (p=0,551). A partir dos dados em análise, foi possível concluir que o manejo cirúrgico permitiu um aumento nos diâmetros da VAS e, consequente, redução no índice de apneia e hipopneia (IAH) para níveis próximos à normalidade. Entretanto novos estudos devem ser realizados para um acompanhamento longitudinal desses pacientes.
