Modeling and optimization of the design of a bandpass filter based on a coaxial resonator
Authors: Zolnikov Konstantin , Achkasov Dmitriy
Published: June 2024

When developing radio receivers in the microwave range, engineers are faced with the task of creating filter circuits with sufficiently high selectivity. Discrete radio elements do not have a sufficient quality factor to construct such filters, therefore, to solve this problem, volumetric electromagnetic resonators are used, in particular vacuum coaxial resonators. This paper provides a review of existing techniques. The main factors influencing the behavior of the electromagnetic field in filters built on the basis of coaxial cavity resonators are also considered, a simulation of such a filter in the S-wave range is carried out, and the main recommendations and relationships used in its design are indicated. As practice shows, an accurate assessment of the parameters of complex microwave structures can only be made using computer numerical modeling methods, however, such calculations take a lot of time if carried out without any preliminary estimates, especially if we are talking about creating a high-order filter with a number of links of 4 or more. At the same time, the method for calculating filters outlined in this article makes it possible to find estimated filter parameters, the further optimization of which is advisable to carry out using numerical methods. The described approach allows us to significantly reduce development time and quickly select the geometric parameters necessary for good electrical matching.
The algorithm for diagnosing leaks of the target product under conditions of uncertainty for the hydraulic system
Authors: Sazonova Svetlana , Koshel' Aleksandr , Panteleev Igor' , Akamsina N. , Kazbanova Irina , Rylev Sergey
Published: June 2024

An algorithm for determining the presence or absence of leaks in functioning hydraulic systems is considered, based on existing methods for determining the location and volume of such leaks. Based on the collected data on the hydraulic parameters of such systems, it is proposed to create a statistical model with all the statistical parameters required for performing calculations. The emphasis is placed on the fact that it is necessary to take into account the features of the hydraulic system in question, depending on its purpose and the technologies used. Mathematical models and methods of leak diagnostics in hydraulic systems are considered, including the identification of the facts of the existence of a leak based on the use of mathematical models to determine the location and size of such leaks. In this article, the research focuses on the detection of leaks with unknown amplitudes based on the verification of two alternative hypotheses for a hydraulic system, taking into account interference from the stochasticity of the demand. It is noted that the transition from the task of verifying two alternative hypotheses to the task of verifying multiple alternative hypotheses or pattern recognition provides a deeper and more comprehensive analysis of leaks. This will allow for more accurate and efficient detection of unusual leaks and provide more reliable protection of hydraulic systems.
The Musical Representation of Jewish Faith in Ernest Bloch's 1923 "Baal Shem Suite"
Authors:   , Swartz Eric Gregory
Published: June 2024

Ernest Bloch (1880-1959) was a Swiss-American composer of music expressing his Jewish nationality. Through his music, he wanted to convey the importance of Jewish faith in countering antisemitism in the early 20th century. This thesis focuses on Bloch's employment of Jewish liturgical modes and melodic embellishments in his 1923 Baal Shem Suite. The Baal Shem Suite is a three-movement piece for violin and piano and is named after the Baal Shem Tov, founder of the Jewish Hasidic movement. As discussed in the document, the piece portrays Hasidic traditions. This thesis provides a Schenkerian analysis of motivic ideas derived from the Jewish modes and their embellishments, while also describing how both elements evoke Jewish spirituality. The document also identifies resemblances between motives in Bloch's suite and preexisting Jewish melodies. As the thesis states, Bloch likely drew inspiration from cantillation of the Hebrew Bible. He was also likely inspired by 19th-century "Jewish pieces" by Franz Schubert and another Jewish composer named David Popper. The document also references 20th century Jewish composers after Bloch who were likely inspired by his Baal Shem Suite. The thesis also identifies the liturgical modes and embellishments employed in some of the composers' musical works.

Queer Faith, Wyrd Hope, Loving Struggle: A Reconsideration and Application of Karl Jaspers' Existenzphilosophie as Liberatory Praxis
Authors:   , Brown Keith Wayne
Published: June 2024

This dissertation delves into the oldest of all philosophical practices: Know thyself. Via a set of self-deconstructive reflections, the work explores the dynamics of existence within the context of marginalized communities, particularly focusing on queer liberation. To do this, the research introduces the concept of "transisting," a term inspired by eschewing mere resistance in order to self-disclose a path for overcoming customary structures of the everyday. Using the Existenzphilosophie of Karl Jaspers in light of Queer Theory, "transistance" provides a philosophical stance that transcends reactionary dynamics and encourages equanimity and overstanding (as opposed to understanding) the status quo. Providing a general overview of phenomenology and a focused perspective on Jaspers' notion of "ultimate boundaries" (or "limit situations"), the dissertation weaves together personal narratives, philosophical discourse, and a critique of contemporary societal norms on the way to a new kind of descriptor: "Wyrding," or the liberatory praxis of self-actualization that lives through weaving wandering wonderment.

Authors:   , Tubby Stephanie Marie
Published: June 2024

This dissertation aimed to expand the current literature's understanding of Indigenous epistemology within contemporary social media environments. The qualitative study used social descriptive analysis from forty TikTok videos and comment threads. The descriptive analysis captured major cultural themes, common informal learning behaviors, and perceptions of Indigenous culture. The findings revealed that Indigenous creators and audiences engaged in questions and answers, personal experience sharing, evaluative feedback, and expressed forms of appreciation to learn with TikTok content. Although the audience perceived Indigenous culture and content positively, community guideline considerations and power challenges to making cultural content available in social media environments still exist.
Examining STEM-Related College and Career Participation among Black Female Graduates from a STEM-Focused All Girls High School
Authors:   , Taylor Ragina Yolanda
Published: June 2024

The purpose of this qualitative case study was to investigate the experiences of Black alumni from an all girls STEM-focused high school to determine their college and career outcomes in STEM. I investigate how Black women describe their experiences related to STEM barriers and supports, their identities, and college and career choices, as they remain one of the most underrepresented groups in STEM. Three Black women, who are alumni from a Grades 6-12 STEM-focused all girls school, were interviewed and participated in a focus group. The study employed a theoretical lens of Black feminist thought intersectionality, and STEM identity in describing experiences through reflection and discourse, which drew on a phenomenological approach. The results of this study provided insights into the experiences of Black alumni from an all-girls STEM high school, and revealed that while the school promoted women's empowerment and a safe environment of familiarity, there is a need for more supportive learning environments that allow their voices; and representation of Black women that center their unique identities and experiences. Participants expressed the need for more guidance beyond high school in understanding the complexities of transitioning to adulthood that affect college and career outcomes. More longitudinal studies are needed in future research to better understand the educational journeys and career pathways of Black women in STEM and all girls schools so that we can prepare a more diverse, skilled and competitive STEM workforce, and empower Black women to excel in STEM fields.
Preparing for the Technical Challenges of Early Beethoven Sonatas: A Teacher's Guide for Intermediate Piano Students with Suggested Repertoire
Authors:   , Zhang Baolong
Published: June 2024

Beethoven's early sonatas have already revealed a complex and varied technique that can present significant difficulties for intermediate piano students. In particular, the absence of systematic methodological guidance, as well as the lack of suitable and high-quality repertoire, can result in students struggling to learn Beethoven's piano technique and not being satisfied with the results. By examining and analyzing the theories of great educators, pedagogues, and performers, some of the standard technical patterns are identified and methods of mastering them are summarized. A sampling of related late-elementary level and intermediate level repertoire is identified, providing study material for students starting to learn the Beethoven sonatas, and serving as a guide for their teachers.
Do Preferences of Performance Feedback Matter
Authors:   , Perdeep Singh Sidhu Samantha Kaur Sidhu
Published: June 2024

Feedback is discussed in many disciplines. In behavior analysis, it has been discussed in terms of its functions, many coming to different conclusions. The present study evaluated whether therapists' preferred temporal and format of feedback shifted or changed during acquisition or maintenance of skills implementing a tact program using a token economy system after a brief exposure to all possible feedback combinations. Three participants completed a questionnaire before they were exposed to a feedback sampling phase and preferred feedback phase. Preferred way of recieving feedback was asked at the beginning of each session. Two out of three participants switched preferences after achieving mastery of task. Task mastery may make feedback delivered at the end of a session more desirable while task acquisition may make feedback delivered at the end of a trial more valuable. Limitations and future research were discussed.
An Analysis of Legal Liability of Florida Public Educators and School Systems for Negligent Supervision of Students
Authors:   , Robinson Deron Thomas
Published: June 2024

The doctrine of sovereign immunity in Florida has evolved over time as the common law and statutory environment within the state has changed. Public schools and public-school employees enjoy some level of immunity protection under both common law and statutory law. Nonetheless, Florida law creates a duty to provide a safe environment for students and creates potential liability in certain circumstances when a public school or public school employee fails to do so. In this dissertation, I analyzed litigation efforts and protections provided to public schools and public-school educators in Florida under the Florida Tort Claims Act (FTCA) of 1973 for claims of negligent supervision of students. This dissertation provided an in-depth analysis of negligence cases, statutes, protections, and lawsuits brought under common law after the passage of the Florida Tort Claims Act of 1973.

Fusion Based Object Detection for Autonomous Driving Systems
Authors:   , Dhakal Sudip
Published: June 2024

Object detection in autonomous driving systems is a critical functionality demanding precise implementation. However, existing solutions often rely on single-sensor systems, leading to insufficient data representation and diminished accuracy and speed in object detection. Our research addresses these challenges by integrating fusion-based object detection frameworks and augmentation techniques, incorporating both camera and LiDAR sensor data. Firstly, we introduce Sniffer Faster R-CNN (SFR-CNN), a novel fusion framework that enhances regional proposal generation by refining proposals from both LiDAR and image-based sources, thereby accelerating detection speed. Secondly, we propose Sniffer Faster R-CNN++, a late fusion network that integrates pre-trained single-modality detectors, improving detection accuracy while reducing computational complexity. Our approach employs enhanced proposal refinement algorithms to enhance the detection of distant objects, resulting in significant improvements in accuracy on challenging datasets like KITTI and nuScenes. Finally, to address the sparsity inherent in LiDAR data, we introduce a novel method that generates virtual LiDAR points from camera images, augmented with semantic labels to detect sparsely distributed and occluded objects effectively and integration of distance-aware data augmentation (DADA) further enhances the model's ability to recognize distant objects, leading to significant improvements in detection accuracy overall.
Metal-Organic Frameworks based on Newly Designed Polycarboxyaryl Linkers: Versatile Cooperative Non-Covalent Interactions and Applications on Small Hydrocarbon Separation and Carbon Capture
Authors:   , Islam Sheikh Mohammad Sirajul
Published: June 2024

Metal-organic frameworks (MOFs) have come to the forefront over the past two decades because of their potential application in hydrocarbon separation under ambient conditions. MOFs are coordination polymers constructed by joining metal ions or metal clusters with organic linkers containing Lewis basic binding atoms. The main focus of the research pursued in this dissertation was to design and synthesize new metal-organic frameworks based on larger polycarboxyaryl linkers developed by our group. The linker design was as such to add a phenyl ring and an unsaturated C2 spacer to the analogous linkers based on linker expansion strategy. The aim of the linker design was to potentially increase the surface area, by virtue of the overall larger linker size, and afford higher adsorption energy to the hydrocarbon molecules (especially to the unsaturated hydrocarbons) owing to π(hydrocarbon)-π(linker) possibly chemisorptive stacking interactions, hence increasing their separations from impurities. To accomplish this goal, we reported several new MOFs and studied their separation abilities. We were also able to report MOFs for the capture of CO2 from industrial flue gases under ambient conditions.

An Evaluation of Chironomidae Pupal Exuviae as Indicators of Changing Environmental Quality in North Central Texas Ponds along an Urban Gradient
Authors:   , Davis Kaitlynn Anne
Published: June 2024

Stormwater retention ponds, constructed primarily for services such as flood control, are abundant in urban landscapes and documented hotspots of aquatic biodiversity. A previous study completed in our lab measured benthic community structure in several stormwater retention ponds in North Central Texas along an urban gradient. Results showed that larval chironomids (Diptera: Chironomidae) were the dominant macroinvertebrates in all of the ponds. It was also determined that differences in pond conditions associated with urban development could only be determined when chironomids were identified to the genus-level. However, collection and identification of chironomid larvae is often time-consuming. The objective of this current study is to evaluate the efficacy of the Chironomidae pupal exuviae technique (CPET) to detect changes in water quality in the same series of urban ponds in North Central Texas over one year. Based on results, CPET is an effective method of analyzing chironomid community response to environmental changes associated with anthropogenic impact. A total of 16,635 pupal exuviae were collected during this study representing 80 chironomid taxa, which included 40 genera across three subfamilies. The chironomid communities differed between ponds in proportion to the intensity of the urban development within their watersheds. Additionally, CPET provided the emergence phenology of a highly diverse chironomid assemblage. Results indicated that urban ponds in North Central Texas can provide refuge for biodiversity in a semi-arid region. As urbanization is projected to increase globally, it is critical to monitor how rapid urban expansion affects biodiversity and freshwater ecosystem conditions.

Authors:   , Robins Boone Janetta Adelle
Published: June 2024

This dissertation aimed to expand knowledge and practical uses of educational technology tools in high-stakes team training environments. This study depicted the real-world impacts of virtual reality (VR) technology on learning and training for the Royal New Zealand Police Academy and those training teams in high-stakes environments. Recommendations for improvement in designing these technologies and training resulted from the study. The study involving VR and the Bedford Workload Scale employed pre- and post-training to determine if using that technology produced statistical significance and improved user learning in VR tactical police training. The final study resulted in similar pre- and post-test results from participants (n = 74), indicating VR may produce realistic levels of cognitive load in virtual participants, and one statistically significant finding for participants who had previous experience using VR, suggesting that cognitive load may be higher during training for those with previous experience. The findings revealed that VR shows promise for increasing the value and efficacy of compliance training in tactical police settings and similar high-stakes team training environments.

A Set of Compositions Inspired by Selected Performance Practices and Notational Systems of Anthony Braxton (b. 1945)
Authors:   , Van Leeuwen Christopher M.
Published: June 2024

Multi-instrumentalist, composer, and music philosopher Anthony Braxton (b. 1945) has developed performance practices and notational systems that are frequently disregarded by scholars of music, despite his prolific output and influence. His restructuralist aesthetic blurs the boundaries between philosophy, visual art, and numerous musical genres and stylistic practices to create an amalgam that is often difficult to categorize due to his perpetual quest to avoid confining definitions. The purpose of this dissertation is to draw attention to various facets of Anthony Braxton's notational and performance practices by using them as a springboard for personal creativity. Inspiration for these original works was drawn from a variety of Braxton's methods, particularly from his quartet music of the 1980s and his Ghost Trance Music, and drew heavily from his concepts of "moment time" and "individual presence," which are key themes arising throughout his music and the literature. Specific compositional techniques were either used verbatim or as inspiration for the development of original practices and are accompanied by an analysis and discussion.
"I forgive the brand because I trust it": Interplay of Brand Trust and Consumer Brand Identification in Influencing Brand Forgiveness
Authors:   , Rahman Md Merajur
Published: June 2024

In the present study, we have explored the role of brand trust and consumer brand identification in evoking brand forgiveness when individuals are exposed to communications related to corporate social responsibility (CSR) wrongdoings. Grounded in attribution theory, we have developed and empirically tested a conceptual model to assess the effectiveness of brand trust in facilitating the attribution of wrongdoings either internally (e.g., believing that the brand had wrong intentions) or externally (e.g., believing that there are other factors beyond the brand's control) in influencing brand forgiveness. We conducted an online experiment utilizing Amazon Mechanical Turk (MTurk) to recruit participants from the U.S. national population (N = 620) following a quota sampling method. Structural equation modeling (SEM) was performed in Mplus to analyze the hypothesized direct and mediation relationships. Multivariate analysis of variance (MANOVA) was performed to test the moderating hypotheses in SPSS (i.e., the interplay of brand trust and consumer brand identification in influencing internal and external attributions). Supporting the hypotheses, we found that brand trust positively influenced external attribution and external attributions, evoking brand forgiveness when individuals are exposed to communications related to CSR wrongdoings. However, contrary to our expectation, we found that the brand trust positively influenced internal attribution which indicated that higher the degree of faith individuals had in the brands, higher their tendency was to consider the possibility that the brand was indeed involved in unethical CSR practices.
Role of Organizational Status, Race, and Emotional Expression in Perceptions of Working Women
Authors:   , Briggs Madasen Renae
Published: June 2024

Social perceptions tied to stereotyping remain a strong contributor to women's experiences, particularly in the workplace. Emotion stereotypes, working in tandem with gendered-racial stereotypes, have been shown to be an important factor in workplace experiences. However, findings on the specific effects of emotional expression have been inconsistent based on the emotions investigated, women's identity characteristics, and workplace contexts. The present project investigated the contributions of race, organizational status, and emotional expression on perceptions of working women across three studies conducted in 2023. Study 1 experimentally investigated the role of organizational status and emotional expression on perceptions of a woman's competence and perceived emotional appropriateness. Study 2 replicated Study 1's methodologically while also experimentally manipulating the race of the woman exposed to participants. Study 3 used qualitative interviewing to investigate woman leaders' experiences with emotions in the workplace. Multi-level modeling for Studies 1 and 2 revealed that participants harbor a strong preference for women displaying neutral emotions, regardless of women's racial identity or power level. In alignment with these results, through reflexive thematic analysis, I identified that the woman leaders in Study 3 face discouragement around their emotional expression. However, they continue to perform various forms of emotional labor, as well as leverage individual emotions to accomplish their goals. Findings can guide future investigations into these stereotypes' influence on workplace interactions and refine our understanding of perceptions that can contribute to inequitable workplace experiences.
Special Education Teacher Job Satisfaction and Its Impact on Teacher Shortages
Authors:   , Hooston Michelle Marie
Published: June 2024

This study examined the link between special education teacher job satisfaction and its impact on teacher shortages. Covariation of administrative support and job satisfaction was evaluated with school sector also evaluated for relevance to special education teacher job satisfaction. A quantitative, cross-sectional research model was used for the data collection and analysis process. The population for the study was special education teachers, and data was extracted from the National Teacher and Principal Survey. Data was collected for this survey by the National Center for Education Statistics using paper documents and internet questionnaires. Multiple regression was used to test the relationships between special education teacher satisfaction and administrative support. The findings indicate as perceived supportiveness and encouragement from administration increased, a corresponding increase in job satisfaction from special education teachers occurred. The findings from this study showed no significant moderation effect of the school sector between public and private schools. These outcomes further suggested that the role of administrative support was crucial regardless of the public or private nature of the school. As a result, it is imperative for school administrators to focus on building a culture of support and encouragement, paying special attention to providing emotional and professional support to teachers. Additionally, schools should consider implementing policies that ensure equitable access to resources and support for all teachers, irrespective of their demographic characteristics. Lastly, considering the minor but significant role of gender in influencing job satisfaction, schools should be mindful of gender dynamics and strive to create a more inclusive and supportive environment for all teachers, regardless of their gender identity.

Authors:   , Taylor Jenna Leigh
Published: June 2024

The present meta-analytic study examined the overall effectiveness of child-centered play therapy (CCPT) and child-parent relationship therapy (CPRT) for children experiencing internalizing problems. After conducting a comprehensive literature search and review, 25 studies published between 2000 and 2023 met the following inclusion criteria: (a) published and peer-reviewed; (b) used CCPT or CPRT as an intervention; (c) participants were ages 3 to 13 or parents of children ages 3 to 13; (d) study outcomes related to children's internalizing problems, such as anxiety, depression, or withdrawal; (e) used single group within study or between study design, including randomized controlled trials and non-randomized controlled trials; (f) published between January 2000 and April 2023; (g) published in English; (h) used standardized measurements; and (i) reported effect sizes, or means and standard deviations, or the author disclosed the means and standard deviations upon request. Final analysis included 28 individual effect sizes using a random effects model to determine the overall effect size for 6 analyses that included CCPT/CPRT combined between, CCPT/CPRT combined within, CCPT between, CCPT within, CPRT between, CPRT within. Moderating variables included gender, age, ethnicity, and number of CCPT sessions. CCPT and CPRT effect sizes were statistically significant and ranged from small to large effects. Results support the use of CCPT and CPRT with children for the reduction of internalizing problems. Procedures and results, including the coding process, limitations, and implications are discussed.
Additive Manufacturing of Refractory Metals
Authors:   , Awasthi Prithvi Dev
Published: June 2024

Keen interest in additive manufacturing (AM) of refractory metals such as tungsten has been motivated by the demand for materials capable of enduring extreme temperatures in aerospace and nuclear applications. The aims of this work were to develop alloy compositions for high-temperature applications in the space propulsion and nuclear fusion sectors, and to establish processing windows for these compositions fabricated using laser powder bed fusion additive manufacturing (LPBF-AM). Tungsten (W)-based alloys are well-suited for high working temperatures because of their high melting points, excellent thermal conductivity, low corrosion resistance, and low coefficient of thermal expansion. The integrated computational materials engineering (ICME) approach was implemented to establish the connections among composition-printability-microstructure-properties-performance framework. ThermoCalc-CALPHAD software was used for Scheil-Gulliver solidification simulation (SGSS) of W-based compositions with various alloying element additions. Chromium, vanadium, and niobium were down-selected as suitable alloying elements based on SGSS results. Further, addition of carbon enhanced printability due to eutectic solidification by the formation of various carbides towards the end of solidification leading to crack-free microstructure as well as being vital for control of oxygen. This work demonstrates the successful manufacturing of multiple crack-free W-based alloy components using LPBF-AM, which had a wide range of working temperatures and enhanced mechanical properties.
Psychological Distress in Collegiate Music Students: Examining Latent Relationships through Structural Equation Modeling
Authors:   , McGoldrick Brian B.
Published: June 2024

The purpose of this study was to characterize psychological distress in collegiate music students via analysis of related latent constructs. The relationships between psychological distress, perceived stress, perception of learning environment, financial stress, social support, and resilience were examined simultaneously via structural equation modeling with psychological distress as the primary endogenous variable. A structural model was developed a priori based on established relationships between the latent variables in the extant literature. Each construct was quantified via indicators drawn from appropriate psychometric inventories. Each inventory, and the total measurement model, was assessed for model fit via confirmatory factor analysis. Following this, structural equation modeling was run with the weighted least square mean and variance adjusted (WLSMV) estimator to test the a priori structural model. Significant direct relationships were found between perception of learning environment and perceived stress and between perceived stress and psychological distress. Significant correlational relationships were found among perception of learning environment, financial stress, social support, and resilience. In this study, perception of learning environment predicted perceived stress in a sample of college music students. Additionally, perceived stress was the primary predictor of psychological distress in this sample.
A Figured World of Whiteness: Teacher Agency in Newcomer Secondary English Classrooms
Authors:   , Sari Gulhan
Published: June 2024

Immigrant-origin students, particularly newcomer students, are a rapidly growing demographic in schools. Educational settings serve as the first contact zones where newcomer immigrant students interact with society. Therefore, their school environment plays a crucial role in their adaptations, forming identities, and analyzing the socio-political issues. Teachers have a profound impact on this process by creating a dynamic interplay between their self-capacities and the learning environment through reflecting on their biases and using their agencies. This study was based on the premise that literacy is an ongoing process of identity formation through social interaction, and it serves as a means of learning about the world. For the purpose of this research an exploratory case study design was employed to investigate the literacy practices of four English as a Second Language (ESL) teachers in two urban high schools. The data was collected by conducting interviews and classroom observations using purposeful sampling. The research findings highlighted that teachers' perceptions and attitudes have a significant impact on the development of students' identities. Teachers used their mainstream coding system to interpret and comprehend the cultural, linguistic, and ethnic diversity that was present in their classrooms. The findings of the study also indicated that power dynamics, standardized exams, and prescribed curricula have an impact on the ways teachers utilize their agency, pedagogy, and facilitation roles. Several implications have been discussed based on the research findings.

Published: June 2024

This study investigates how the terms "greenwashing" and "fashion sustainability" are transmitted among social entities, as well as who impacts this social discourse in terms of structure, pattern, and substance. Three specific research objectives are: identifying opinion influencers in greenwashing and sustainable fashion communication, determining the diffusion structure of greenwashing discourse in social media (i.e., Twitter) communication, and investigating the associated social discourse regarding keywords' semantic networks on Twitter. This study employs social network analysis (SNA) to perform cluster mapping and semantic analysis on Twitter networks, with a focus on investigating the social discourse around greenwashing in fashion sustainability initiatives.The identification and diffusion of content and discourse on Twitter concerning sustainability and greenwashing in the fashion industry may be facilitated by utilizing theories such as two-step flow communication and selective exposure theory. This study discovered the critical significance of social influencers, diffusion structures, and communication in generating the discourse of greenwashing in fashion sustainability practices through shared networks. Based on the findings, we provide crucial theoretical contributions and managerial implications for businesses concerned with greenwashing and sustainable fashion. Findings from data networks may help organizations and people understand communication patterns, community growth on social media, and different types of discourse inside the network.

W ostatniej części omówiono szczegóły pobytu Bonifilego w Krakowie w latach 1444-1450 oraz jego inicjatyw na rzecz Polaków w Rzymie w latach 1450-1453. W tej części szczególną uwagę poświęcono relacjom Marka z kilkoma wybitnymi przedstawicielami Uniwersytetu Krakowskiego i duchowieństwem. Dlatego też głównym celem artykułu jest rekonstrukcja biografii Bonifilego w oparciu o dokumenty bazylejskie i polskie oraz wskazanie jego wieloaspektowych powiązań z elitą intelektualną i wyższym duchowieństwem Polski późnośredniowiecznej, m.in. ze Stanisławem Sobniowskim, Janem Elgotem, Mikołajem Spicymirem, Janem z Dąbrówki, Janem Długoszem i Zbigniewem Oleśnickim.

W 1986 roku Hiszpania, której integralną częścią jest Katalonia, dołączyła do Wspólnot Europejskich, a siedem lat później powstała Unia Europejska. Artykuł podejmuje problematykę aktywności Katalonii we Wspólnotach Europejskich/Unii Europejskiej w latach 1986-2021. Jego celem jest ukazanie ewolucji polityki tej wspólnoty autonomicznej w WE/UE w kontekście budowania jej pozycji politycznej. Dla przeprowadzenia badań dotyczących uczestnictwa Katalonii w WE/UE jako elementu budowania jej autonomistycznej polityki posłużą określone pytania badawcze. Problem badawczy obejmuje m.in. relacje Katalonii z władzami centralnymi państwa hiszpańskiego, udział Katalonii w kształtowaniu stosunków Hiszpanii z WE UE oraz pośrednie i bezpośrednie zaangażowanie administracji katalońskiej na poziomie wspólnotowym instytucjonalnym. Aby przeprowadzić dogłębną analizę, autor odwołuje się do danych ilościowych i jakościowych oraz do literatury przedmiotu.
Optimal Regularized Online Allocation by Adaptive Re-Solving

Online resource allocation is challenging when the decision maker aims to achieve fairness, load balancing, diversity, and so on. In “Optimal Regularized Online Allocation by Adaptive Re-Solving,” Ma, Cao, Tsang, and Xia examine the online allocation problem equipped with a nonseparable regularizer, which is commonly adopted to promote fairness and beyond. Under certain regularity, smoothness, and nondegeneracy assumptions of the dual problem, the authors show that a dual-based optimization strategy with adaptively updated resource constraints and history-based re-solving can achieve optimal logarithmic regret, even without the notorious log-log factor. The authors also demonstrate that an optimal regret upper bound can be achieved using infrequent re-solving and that an even faster algorithm is available if nearly optimal regret performance is acceptable. Their results demonstrate that optimal logarithmic regret is achievable under the max-min fairness or load-balancing constraints.

Background: Hypertrophic pachymeningitis (HP) is a disease with diverse aetiologies, including the autoimmune one, either associated with antineutrophil cytoplasmic antibodies or immunoglobulin G4. Case description: A 65-year-old woman with a history of systemic arterial hypertension, presented with intense progressive headaches. HP and hemispheric vasogenic oedema were observed by nuclear magnetic resonance (NMR) study. During the six months before the headache, she had developed progressive hearing loss which she attributed to age. A biopsy of dura mater showed necrotising vasculitis with peripheral inflammatory infiltrate, made up of accumulations of epithelioid cells and multinucleated giant cells, and abundant eosinophils. A final diagnosis of HP with eosinophilic granulomatosis with polyangiitis (EGPA) was made. Discussion: The patient had eosinophilic granulomatosis with polyangiitis (EGPA) histology, ANCA-negative serology and HP. This case is important because it shows that EGPA seems to have a spectrum of clinical diseases, including HP with negative serology, and bilateral sensorineural hearing loss. Conclusion: We are facing a wide spectrum of EGPA, breaking the paradigm of only systemic involvement.
Navigating diagnostic challenges: a case of acquired hepatocerebral degeneration presenting as worsening hepatic encephalopathy in chronic liver disease

This case report details the complex diagnostic odyssey of a 60-year-old female grappling with chronic liver disease, initially diagnosed with hepatic encephalopathy (HE). Despite initial treatment with lactulose and rifaximin, her neurological symptoms worsened, leading to the identification of concurrent acquired hepatocerebral degeneration (AHD). This condition is characterised by cognitive decline, movement disorders and distinctive imaging abnormalities. The discussion highlights the challenges in distinguishing AHD from HE, underscoring the sophisticated diagnostic and management strategies required for such intricate cases in the realm of chronic liver disease.
Unveiling the deadly dance of hypocalcemia and lactic acidosis in a 59-year-old woman with B-cell lymphoma

Calcium plays a crucial role in the heart’s electrical conduction system and facilitating the contraction of cardiac muscles. Hypocalcemia can result in electrocardiogram findings such as a prolonged QTC interval and eventually torsade de pointes, which in severe cases can progress to cardiac arrest. In cases of B-cell lymphoma, hypocalcemia may arise from various factors. Tumor infiltration can disrupt calcium homeostasis by affecting the parathyroid glands or bone tissue. Acidosis in the context of B-cell lymphoma can cause significant cardiovascular adverse effects. It will reduce peripheral vascular resistance and cardiac muscle contractility, promote dysrhythmias, and disturb oxygen uptake in the lungs. These combined effects markedly compromise cardiac function, increasing the likelihood of cardiac arrest. These mechanisms necessitate comprehensive management strategies in B-cell lymphoma patients. In this case report we present a case of cardiac arrest in a 59-year-old female woman with hypocalcemia and lactic acidosis secondary to B-cell lymphoma.
