Dynamical Systems on Graphs
Authors:   , Sclosa Davide
Published: January 2025

A group of people exchanging opinions. An artificial neural network
making predictions. A virus spreading through a population. A brain
retrieving a memory. A server allocating tasks to multiple computers. A
power grid balancing supply and demand. A self-replicating machine in a
cellular automaton. A random walk on the set of vertices of a graph. A
random walk on the set of graphs with given number of vertices.
Each of these phenomena can be viewed as a dynamical system on a graph,
where vertices represent evolving quantities and edges represent interactions.
This thesis concerns the relation between graph structure and dynamics.
The first part of the thesis considers deterministic dynamics on finite
graphs. For di!usive systems, we prove an upper bound on the dimension of
the equilibrium set based on graph homology and a lower bound based on
graph coverings. For the specific Kuramoto model, we solve a conjecture by
constructing finite graphs with infinitely many stable equilibria, and classify
nilpotent equilibria using Eulerian cycles. For general systems of equations
with “a graph structure”, we show how solutions are controlled by subgraphs
and apply the result to dynamical systems as well as spectral graph theory.
The second part of the thesis concerns stochastic dynamics on finite
graphs. More precisely, it considers occupancy processes, which include
several interactive particle systems and random graph models as particular
cases. We prove that finite-time deviations from typical behavior are controlled
by the geometry of the graph as perceived by a random walker on the vertices.
The third part of the thesis concerns dynamics on graph limits and their
symmetries. Graph limits are describe the structure of graphs as the number
of vertices grows to infinity. We prove that symmetries of graph limits lead
to symmetries of their associated—typically infinite dimensional—dynamics,
and use this fact to determine invariant patterns.
Relations between graph structure and dynamics heavily depend on the
specific evolution equations considered. Certain relations are model-specific,
others vary between discrete and continuous time, and still others di!er
between deterministic or stochastic dynamics. Yet, many of the ideas and
tools developed for one class of graph dynamical systems often shed light on
others.
The impact of an international advisory board on the management of cancer during pregnancy
Authors:   , Heimovaara Joosje Heleen
Published: January 2025

When cancer is diagnosed during pregnancy, multidisciplinary care and the opinion of experts is of most importance to achieve the best possible outcome for both mother and child. Before this PhD thesis, no central information or access to an advisory board is available for clinicians with questions regarding the treatment of pregnant women with cancer. This thesis examines the impact of an international advisory board on the management of cancer during pregnancy. The research explores the establishment of the Advisory Board on Cancer in Pregnancy (ABCIP), focusing on its role in improving care through multidisciplinary collaboration and real-time consultations. The thesis also discusses clinical challenges in treating cancer during pregnancy, including maternal mortality, treatment options for specific cancers like sarcoma, and the use of innovative therapies such as immunotherapy and proton therapy. Key findings include the need for structured care and the potential benefits of advisory boards in standardizing treatment and improving outcomes for both mother and child. Future research directions involve enhancing knowledge on cancer treatment during pregnancy, especially for emerging therapies and palliative care.

Published: January 2025

Deepwater seismic data acquisition and processing pose significant challenges due to the complex subsurface conditions and the need for high-resolution imaging in harsh offshore environments. This paper explores innovative processing adaptations for deepwater seismic data, focusing on conceptual advances in 3D and 4D imaging techniques designed to enhance the interpretation of complex reservoirs. The paper introduces a conceptual framework that integrates advanced signal processing algorithms, machine learning models, and real-time data analytics to optimize seismic data quality and improve subsurface imaging. Key innovations discussed include the use of multi-frequency and multi-azimuthal data collection techniques, which enable more precise imaging of geologically complex reservoirs. These techniques allow for improved resolution of target layers and fault zones, crucial for accurate reservoir characterization. Additionally, the integration of machine learning algorithms facilitates automated detection of seismic events, noise suppression, and adaptive data processing, significantly enhancing imaging quality and reducing manual intervention. The adaptation of 4D seismic imaging, which incorporates time-lapse data to track changes in reservoir conditions, is also explored. By combining 3D imaging with dynamic monitoring over time, 4D imaging offers a more comprehensive understanding of fluid movement, reservoir behavior, and production optimization. The paper discusses the benefits of integrating advanced seismic inversion techniques with 4D data to improve the accuracy of reservoir models and guide decision-making for field development. Real-time data analytics play a critical role in this conceptual framework, enabling immediate feedback on seismic survey quality and adjustments during acquisition. This reduces operational downtime and ensures that the data collected is of the highest quality, optimizing survey time and cost efficiency. A case study demonstrates the effectiveness of these innovations in improving seismic imaging for a deepwater oil field, showcasing significant advancements in imaging resolution and cost efficiency. The paper concludes by highlighting future research directions, including the integration of artificial intelligence for predictive modeling and further refinement of 4D seismic technologies.

This study aims to analyze the noise pollution levels in significant areas in Damoh City. Noise is usually an unwanted, unpleasant or disagreeable sound that causes uneasiness.  Today, one of the major causes of environmental pollution due to human-caused or influenced activities is noise pollution. The present study is concerned with assessing ambient noise levels in different locations of Damoh City in August 2024. Noise levels were studied at 10 locations in two distinct zones (commercial and silent) in Damoh City. Recorded noise data were elucidated as parameters Leq, L10, L50, L90 and LNP. The Leq and LNP Values in different hours at different locations compared with the prescribed standard of the Central Pollution Control Board were observed. The study area's sound level was much above the maximum permissible limit per hour. For commercial locations, LNP was in the range of 74.0 -114.3 dB(A) and for silent locations, LNP was in the range of 63.9 -76.8 dB(A). This study reveals that different areas of Damoh City are highly susceptible to noise pollution, and there is a warrant to adopt suitable control measures to reduce noise.

Authors: Chairunnisa Ema , M. Asyrakal  , Haris Abdul , Yazid Syamsurizal
Published: January 2025

This study aims to elaborate on the concept of children's character education within the family environment according to Buya Hamka. It employs a qualitative approach with a library research method. The data for this study were collected using documentation techniques, which involved reviewing and searching for information in the form of notes, books, journals, and other general scientific works. The analysis was conducted using content analysis techniques. The findings reveal that Buya Hamka emphasizes that the foundation of children's character education begins in the family environment. In this context, parents, specifically fathers and mothers, play a central role in shaping a child's character. The primary aspect of children's education starts and is implemented within the family setting. According to Buya Hamka, several methods can be applied to instill and shape a child’s character. These methods include exemplary behavior, advice, practice, habituation, discussion, and punishment. Additionally, three key steps for character building are identified. Firstly, parents, as the primary educators, must possess a pure and sincere spirit in nurturing their children’s character. Secondly, parents are obligated to provide advice to their children. Thirdly, parents should frequently engage their children in discussions.
The CHIKUNGUNYA FEVER SURVEILLANCE, OUTBREAK INVESTIGATION, RESPONSE AND ITS DETERMINANTS FACTORS IN PESHAWAR, PAKISTAN: A DESCRIPTIVE AND UNMATCHED CASE-CONTROL STUDY
Authors: Irshad Roghani  , Muhammad Ashfaq  , Muhammad Junaid Hassan Sharif  , Qasim Khan  , Noreen Taj
Published: January 2025

Background: Chikungunya is a viral disease transmitted by Aedes aegypti and Aedes albopictus mosquitoes. It is characterized by fever, joint pain, and rash. The first officially confirmed outbreak in Peshawar, Pakistan, was identified in Shamshatoo Camp, which is an Afghan refugee settlement, in 2024. The objective of this study was to identify the determinants of the outbreak, access the magnitude of the outbreak, and implement control measures. Methods: The study design was a descriptive study followed by an unmatched case-control study (1:1 ratio) conducted between October 10 and November 26, 2024. Data were collected by administering structured questionnaires, active case search, and review of health facility records. In all, 154 cases were recruited and an equal number of controls. Univariate and multivariable logistic regression were computed to determine the relationship between the outcome and associated factors. Mosquito breeding sites were noted in the environmental survey, and later, laboratory testing confirmed 14 positive chikungunya cases out of 43 samples. Results: During the outbreak a total of 416 cases were reported with the peak on November 1, 2024 (32 cases). Females constituted 55% of the total cases and the most affected group belonged to the age group 10–19 years. Other significant risk factors were the presence of mosquito larvae in households (OR 3.2; 95% CI 2.0–5.2), open storage containers for water (OR 3.0; 95% CI 2.0–4.9), and less use of mosquito protection measures (OR 3.4; 95% CI 1.7–6.8). Precaution measures on awareness against vector-borne diseases showed protective effects (OR 0.03; 95% CI 0.01–0.14). Conclusion: The outbreak was driven by inadequate mosquito control, favourable climatic conditions (20–30 °C), and community laxity in eliminating breeding sites. Targeted interventions, including vector control, health education, and distribution of insecticide-treated nets, contributed to the decline in cases. However, the absence of a dedicated health facility and poor health-seeking behaviour remain challenges. Comprehensive surveillance and community engagement are essential to prevent future outbreaks.

ABORDAGENS TERAPÊUTICAS NA DIABETES MELLITUS TIPO 2: AVANÇOS E DESAFIOS CLÍNICOS
Authors: de Mendonça Matheus Jannuzzi Moreira , De Macedo Ryan Rafael Barros
Published: January 2025

INTRODUÇÃO: O diabetes mellitus tipo 2 (DM2) representa uma condição crônica e progressiva que afeta uma proporção crescente da população mundial. Sua prevalência tem aumentado substancialmente, impulsionada por fatores como o envelhecimento da população, a urbanização, a dieta inadequada e o sedentarismo, levando a uma crescente carga para os sistemas de saúde. A relação entre a obesidade e o DM2 é bem documentada, uma vez que a obesidade amplifica a suscetibilidade genética e os fatores ambientais, contribuindo para a resistência à insulina, uma característica central da patogênese do DM2 (RUZE et al., 2023). Além disso, a expansão ectópica do tecido adiposo e o acúmulo de determinados nutrientes e metabólitos comprometem o equilíbrio metabólico, exacerbando a desregulação imunometabólica e acelerando a perda funcional das células β, o que culmina na elevação da glicemia.

Desta forma, este estudo teve como objetivo principal, analisar o poder de predição das competências socioemocionais baseadas em mindfulness sobre o estresse em professores. A coleta foi realizada com uma amostra de 203 participantes. Para a coleta de dados foram utilizados dois instrumentos. O primeiro foi uma escala de competências socioemocionais baseada em mindfulness e o segundo, uma escala de estresse no trabalho. Os resultados mostraram que alguns fatores de competências socioemocionais foram capazes de prever as dimensões de apoio social e demanda, do instrumento de estresse no trabalho. Complementarmente, foram identificas algumas diferenças significativas de escores de competências para as variáveis sexo e idade. Conclui-se que as competências socioemocionais baseadas em mindfulness são preditoras de estresse no trabalho.

Introduction: The available scientific evidence3-4 allows us to state that the development and progression of heart failure are underlain by immunological and inflammatory mechanisms that are associated with oxidative stress. Objective: To determine the characteristics of hematological markers of inflammation in hospitalized patients with HF on admission.Material and methods: A descriptive-cross-sectional study of 100 patients who were admitted to the Cardiology ward with a diagnosis of HF from 2018 to 2020 was carried out. For data collection, the survey that was filled out during the review of medical records was used. clinics once the patient is discharged. For the processing, a database was created with the SPSS system. The principles of the Declaration of Helsinki were respected.Results: It was shown that the greatest left atrial dilation is significantly correlated with the elevation of the elevated neutrophils / lymphocytes (NRL) (80%), while only 20% of these patients present the NLR up to 2.9. There is a significant association between the RNL up to 2.9 and the state at discharge alive, represented by 63%, as well as the elevated platelet/lymphocyte ratio (≥ 116) with the deceased discharge (100%), while the live discharged with this same condition were only 22.8%.Conclusions: The hematological markers of inflammation and oxidative stress, Neutrophils/lymphocytes and platelets/lymphocytes ratio, are characterized by their significant association with mortality in patients hospitalized for heart failure.

Authors: Milivoy Ancieta
Published: January 2025

IntroductionThe study analyzed the phases of eruption and dental chronology, highlighting the importance of primary teeth in dental development and the consequences of their premature loss. The order of eruption and exfoliation of primary teeth was described, emphasizing that the loss of space due to the absence of these teeth generates malocclusions and affects the development of the permanent dentition.DevelopmentThe phases of dental eruption (pre-eruptive, pre-functional eruptive and functional eruptive) and the factors that influence their chronology, such as genetics, climate, nutrition and systemic diseases were discussed. The clinical manifestations related to dental eruption, such as irritability and excessive salivation, were also discussed. In addition, the main causes of premature loss of primary teeth, including caries, trauma and congenital anomalies, and how these affect the correct eruption of permanent teeth, were highlighted.ConclusionPremature loss of primary teeth has a significant impact on the masticatory function, phonetics and psychological well-being of the child, in addition to generating malocclusions and alterations in the chronology of the dentition. Prevention through proper oral hygiene, healthy diet and early dental care is crucial to avoid complications and promote comprehensive oral health.

Urinary tract infections are of great importance in the health care of patients, as they are caused by bacteria that enter the urethra and then the bladder. A urinary tract infection can occur at different points in the urinary tract including the bladder, kidneys, ureters, urethra. Women tend to get them more frequently, because their urethra is shorter than that of men. This causes a high percentage of morbidity. The aim of this intervention plan is to work with the nurses of the different shifts in the adult ICU to reduce urinary tract infections. It will be oriented to the training of urinary catheter placement and maintenance, therefore, an intervention work will be addressed, specifying the technique, to achieve the proposed objective. That is why we will work together with the head of the service, to see the daily provision of nursing staff and thus be able to plan the training schedule, also will be provided with different tools to reduce urinary tract infections. Likewise, the process will be continuously supervised and an evaluation instrument will be provided..
