Military interventions in the unipolarity: Lessons for security dynamics of US-China relations amid Trump's second term
Authors: Stekić Nenad
Published: February 2025

Humanitarian interventionism, a hallmark of the unipolar era following the Cold War, has been widely debated as a mechanism for addressing alleged human rights violations and safeguarding global security. Rooted in principles such as the Responsibility to Protect (R2P), these interventions have often intersected with the strategic interests of dominant powers, particularly the United States. This paper examines the evolving dynamics of humanitarian intervention within the shifting geopolitical landscape, focusing on the implications for USChina relations during President Donald Trump's second term in office. Building on historical precedents and theoretical frameworks, the study analyzes how the US might invoke humanitarian intervention as a dual-purpose tool - asserting moral leadership while countering China's growing influence in regions of strategic interest. It further explores the challenges of applying lessons from interventions in the unipolar era to a world increasingly defined by multipolarity and strategic rivalry. By contextualizing Trump's assertive foreign policy stance and examining potential justifications for interventionism, the paper offers critical insights into how humanitarian motives might align with or mask broader geopolitical objectives. Consequently, this analysis sheds light on the security implications for US-China relations, contributing to the wider discourse on the intersection of ethics, power, and global governance.
Digitalization and country image: Key influencing factors (a case example of Nigeria)
Authors: Wynn Martin , Adejumo Dauda , Vale Vera
Published: February 2025

This article examines the multi-faceted role of digital technologies in shaping a country’s image, with particular reference to Nigeria, the largest economy in West Africa. Digital technologies are playing an increasingly significant role in the development of country image, impacting cultural, economic, and political aspects, and this is drawing increasing interest and focus from the academic community. Here, the ways in which digital technologies contribute to the creation and projection of a country’s image are investigated via a two-stage research process. Firstly, a systematic literature review identifies key influencing factors (IFs) that are represented in a provisional conceptual framework (PCF). The IFs are the impact of social media, the level of digitalization and support infrastructure, cybersecurity vulnerabilities, technology innovation, standards and governance, and education and awareness. Secondly, a questionnaire based around the PCF was circulated to 10 leading academics and managers, in which they were asked for their views and experiences, and their assessment of the significance of each of the IFs. The exploratory paper concludes that digitalization has a significant influence on a country’s image, affecting perceptions of technological advancement, economic development, access to information, social transformation, and global competitiveness, and suggests that the framework put forward here may act as a model for cross-country comparisons in subsequent studies.

ZNAČAJ IZRADE I ZAŠTITE METALNIH KONSTRUKCIJA
Authors: Mehmedović Behrudin
Published: February 2025

Metalna konstrukcija, u građevinarstvu, je nosivi sustav građevine pretežno sastavljene od metalnih elemenata. Ta se konstrukcija primjenjuju u gotovo svim područjima građevinarstva: zgradarstvu (hale, hangari, garaže, neboderi, tornjevi, krovišta, nadstrešnice, dimnjaci, skele), mostogradnji (žel- jeznički, cestovni, pješački, cjevovodni mostovi) i hidrogradnji (zapornice, splavnice, cjevovodi pod tlakom, kesoni), te za transportna postrojenja (dizalice, žičare, kranske staze), spremišta (rezervoari, silosi, bunkeri), rudarska i metalurška postrojenja (bušaći i izvlačni tornjevi, visoke peći, podgrade), stupove različite namjene (rasvjetni, dalekovodni, antenski, radijski i televizijski, radarski) i drugo. Pogodnost primjene metala za nosive konstrukcije zasniva se na njihovoj velikoj čvrstoći, elastično- sti i plastičnosti. Među metalima, zbog jeftinih valjanih proizvoda, uveliko prevladava čelik, dok se mnogo lakše, aluminijske slitine primjenjuju kada vlastita težina nosive konstrukcije ima presudno značenje. Metalne konstrukcije izrađuju se od osnovnih elemenata: nosača, štapova, lamela, limova, cijevi i specijalnih profila.
SIGURNOST RAČUNALNIH MREŽA

Published: February 2025

Računala koja povezujemo u mrežu služe da bismo izmjenjivali podatke, koji se nalaze u radnoj memoriji računala. Sam prijenos podataka može se obavljati isto tako i elektroničkim signalima, a te veze mogu biti bežične mreže, i žičane mreže. Bitovi koji šalju jedan za drugim istodobno odgo- varajućom brzinom, i pretvaraju digitalni signal u analogni signal i obrnuto obavljaju moderno. Računala također mogu biti povezana i u lokalnu mrežu i u razgranatu mrežu. Svako računalo koje je spojeno na mrežu ima svoj jedinstveni broj (adresu) iz koje se može prepoznati na kojem je kon- tinentu, i u kojoj je državi te na koju je adresu poslužitelj povezan. Podaci se šalju u skladu s prije dogovorenim protokolom, i to u obliku paketa. Sigurnost zaštite osjetljivih podataka i dokumenata postoji već odavno u svijetu. Tokom povijesti mnogo se metoda razvijalo u pogledu zaštite podataka i sigurnosti na internetu. Metode pružanja zaštite na internetu ponekad nisu bile efikasne i nisu pružale u dovoljnoj mjeri zaštitu koja je bila potrebna. Razvojem kriptografije i tehnologije otkriveni su vrlo dobri načini kriptiranja i zaštite dokumenata. Informacijski sustavi su temelj osnovnog i modernog poslovanja. Njihova temeljna zadaća je da se baziraju na sustav mreža,te njihovo poslo- vanje i sigurnost. Zbog toga je izuzetno važno da se što bolje upoznamo sa sigurnosnim problemima računalnih mreža, i načinima na koji se ti problem rješavaju. Današnje se računalne mreže sve više temelje na TCP-IP protokolu, zbog jednostavnog definiranja adresa uređaja na mreži te zbog mo- gućnosti povezivanja na internet i korištenje njegovih mrežnih usluga. Planiranje zaštite sigurnosnih sustava temelji se na ispitivanju poznatih prijetnji te prijedloge rješenja kao rezultat kompromisa. No efikasna zaštita ne primjenjuje samo jedno rješenje, već kombinaciju puno više različitih drugih opcija zaštite i sigurnosti mreža. U ovom radu ćemo se u kratkim crtama osvrnuti na općenito sustav mreža, a isto tako i njihova sigurnost, nastanak, te njihovu podjelu.

Authors: Mazin Zeki Nameer , M. Z. Othman Karam , Fakri Mustafa Yasser
Published: February 2025

The greater development in the computational tools and the presence of a huge number of established chemical libraries emerge the inquiry about the ability to integrate the computational techniques in the drug discovery process. This review emphasizes the role of computational tools and software to accelerate the steps in the drug discovery pipeline. The data were gathered from the trendiest research articles and reviews that were indexed in the well-established scholarly search engines. Different vital techniques, such as virtual screening, pharmacophore modeling, molecular docking, molecular dynamic simulations, and quantitative structure activity relationship, are widely employed for target recognition, lead refining, and forecasting binding behavior at the atomic level. The advancement in artificial cognitive computing software significantly expanded the capabilities for rapid analysis of substantial data sets and the generation of toxicity and bioactivity predictive models of drugs. The contributions of these software tools tackled global problems, like drug repurposing during the coronavirus outbreak, and the direction toward personalized medicaments highlight their crucial role in the swift discovery of new treatments. In addition, computational tools are widely employed to enhance the drug formulations, which leads to discovering drugs with optimum pharmacokinetic and toxicity profiles. The difficulties in analyzing the multi-target binding behaviors and the limited success rates of the generated candidates in the experimental validations were the main existing limitations. However, the steep development in the field of artificial intelligence and the hybrid biochemical-computational approaches provided promising horizons to tackle these limitations. Chemical computational tools significantly affect the future of pharmaceutical research by boosting the drug discovery process toward affordable and efficient medicaments.

Published: February 2025

This study explores coffee visitor profiles in slow bar at Bangkok and Jakarta, two prominent megapolitan cities in Southeast Asia. A quantitative approach using structured surveys was conducted with 82 respondents in Bangkok and 80 respondents in Jakarta. Purposive sampling targeted visitors who had visited slow bars within the past three months. Data were analyzed using descriptive statistics, including frequency distributions and cross-tabulations, to identify consumer patterns and differences. The results indicate similarities in income levels and visitation frequency, with most visitors earning above the regional minimum wage and favoring weekly visits. A preference for local coffee origins was observed, with 53.6% of Bangkok respondents and 60% of Jakarta respondents favoring local beans. However, notable differences emerged in gender distribution (women dominate in Bangkok at 53.7%, while men dominate in Jakarta at 87.5%) and brewing method preferences (Bangkok favors Espresso Extraction at 51.22%, while Jakarta prefers Pour Over at 61.25%). This study provides critical insights into evolving coffee consumption trends in megapolitan cities, offering opportunities for targeted marketing strategies, local coffee promotion, and experience enhancement to further develop the slow bar industry.

Published: February 2025

Inarguably, the choice of the appropriate method to use for country population projection still remains one major factor to consider in production of precise population forecast of country. This study aims at providing an investigative study of population forecast approaches of the yearend population in Nigeria using the National Population Commission population projection method (i.e. the cohort component) as based comparison. Precisely this study empirically examined the performances of five population projection approaches namely ARIMA, Linear Regression, Log-Linear Regression, Exponential Regression and Cohort Component methods in modelling and forecasting the total Nigeria population using the nation population data spanning from 2006 to 2022. The empirical results established ARIMA(1,2,0) with lowest AIC and returned the model as the most parsimonious ARIMA model. Also, the empirical results revealed ,  and  as the estimated Linear Regression, Log-Linear Regression and Exponential Regression model respectively. Similarly, a Cohort Component model was fitted for the total population. Results from four accuracy measure criteria i.e., RMSE, MSE, MAE and MAPE criteria established that the estimated Exponential Regression   with the minimum accuracy values across the four (4) evaluation criteria. This study concludes that Exponential Regression based population projection approach outperformed the ARIMA, Linear Regression, Log-Linear Regression and Cohort Component methods, thus Exponential Regression based population projection approach is more robust and efficient to project the Nigeria total population for the examined period. This study recommended Exponential Regression based extrapolation approach to be employed over the conventional Cohort Component approach for modelling and predicting total population of a country over time.

Authors: Podungge Moh. Reza , Mangkona A. Arsita Soraya , Sirajuddin Zaenal
Published: February 2025

Pedestrian pathways are public facilities designed to support the comfort and safety of pedestrians. However, the pedestrian pathway in front of the Faculty of Engineering is often underutilized by its users. This phenomenon is believed to be influenced by various environmental factors, particularly the high intensity of sunlight. This study aims to identify the factors contributing to the low usage of the pedestrian pathway. Using a qualitative approach, the research employs in-depth interviews, field observations, and document analysis. Data were collected from various informants, including students and lecturers, to gain diverse perspectives on the issue. The results of the study indicate that intense sunlight is one of the main obstacles, exacerbated by a lack of supporting elements such as shade trees or canopies. In addition, the poor condition of the pedestrian pathway, including inadequate connectivity and discomfort during use, also affects its utilization. These findings provide a deeper understanding of the barriers to pedestrian pathway usage in the Faculty of Engineering area and can serve as a foundation for strategic improvements to the facilities, promoting more comfortable and sustainable mobility.

Authors: Darwis Darwis , Sirajuddin Zaenal
Published: February 2025

This research explores the dual function of the breakwater in the coastal area of Palu Fishermen Village, which not only serves as a barrier against large waves but also as a popular gathering spot for the local community. Through direct observation and in-depth interviews with breakwater users, it was found that this structure is visited at least once a week by local residents. Activities carried out in this area are diverse, including strolling, fishing, relaxing, and light exercises such as jogging. Visitors feel safe and comfortable due to the availability of various culinary facilities, such as somay and meatball vendors, which add to the area's appeal. Beyond its protective function, the breakwater also plays a significant role in enhancing social interactions among community members. This area serves as an ideal meeting point for interacting with friends and family, strengthening community bonds, and providing space for recreational activities. The findings of this study highlight the importance of inclusive design in public infrastructure that considers not only technical aspects but also social and recreational functions. Thus, the breakwater in Palu Fishermen Village functions not only as coastal protection but also as a public space that supports the social well-being of the local community.

Authors: Nofiyanti Fifi , Rahmanita Myrza , Adawiyah Robiatul , Abduh M. Syaltut
Published: February 2025

Hereditary legends play an important role in cultural preservation and cultural-based tourism development. In the context of sustainable tourism, the integration of local wisdom, including legends, can be an effective strategy to achieve the Sustainable Development Goals (SDGs), especially in cultural preservation (SDGs 11) and local economic development (SDGs 8). However, the phenomenon of fading interest in folklore among the younger generation and the potential for over-commercialization in the development of cultural attractions are challenges that need to be overcome. This study aims to explore the role of local wisdom-based tourist attractions, especially legends, in supporting sustainable tourism and cultural preservation. Based on the literature review, this study identified five main indicators in the development of tourist attractions, namely economy, socio-culture, environment, education, and community welfare. The results of the study indicate that the management of legend-based tourist attractions not only has a positive impact on the local economy, but also increases cultural awareness, supports environmental preservation, and plays a role in the education of the younger generation. However, active involvement of local communities and careful management are essential to optimize this potential. Thus, this study emphasizes the importance of maintaining a balance between commercialization and cultural preservation in the development of sustainable legend-based tourism.

Authors: Epga Gabkwet Anthony , Owoicho Igoh Emmanuel , Jimoh Salaam Abdul , Folake Taiwo Yetunde , Moses Danjem Samuel , Daniel Pam Stephen
Published: February 2025

Introduction: Lumbosacral transitional vertebrae (LSTV) are common spinal congenital anomalies that affect both genders, and their association with low back pain has been debated in the literature for decades.
Objective: To assess the prevalence and association of LSTV and low back pain (LBP), evaluate the association between degenerative lumbosacral changes and LSTV using standard lumbosacral radiographs in a Nigerian population.
Methods: Standard anterior-posterior and lateral views of the lumbosacral spine of 399 patients who presented with low back pain (LBP) were reviewed and the transverse processes of L5 were graded according to Castellvi classification of LSTV.
Results: Out of the 399 radiographs reviewed, 168(42.1%) were males while 231(57.9%) were females with a ratio of 0.7:1. The prevalence of LSTV in the study was 30.1% with a higher rate in men than in women (35.1% vs 26.4%). Of the 120(30.1%) individuals with LSTV, 23.3% were Type I (dysplastic enlarged transverse process), 6.3% were Type II (pseudoarticulation), and 0.5% were type IV (one transverse process fused and one with pseudoarticulation). Of the 399 patients with low back pain, 218(54.6%) had degenerative changes of the lumbosacral spine while 181(45.4%) showed nil degenerative changes of the lumbosacral spine. The study also showed, 22(10.1%), 33(15.1%), 5(2.3%) and 12(5.5%) who had degenerative change had type IA, IB, IIA and IIB respectively while 18(9.9%), 20(11.0%), 4(2.2%) 4(2.2%) and 2(1.1%) without degenerative change had type IA, IB, IIA, IIB, and type 4 respectively.
Conclusion: Our study demonstrates an association between LSTV with LBP and the male gender shows a higher prevalence of LSTV when compared with the female gender.

Authors: Amah Cletus Okey , Jumbo Victor Kalada
Published: February 2025

This study is anchored in the resource-based view theory as well as the relational view theory, and sought to investigate the relationship between Supply chain Integration and Organisational Agility in the hospitality industry. With specific focus on four-star hotels in the iconic Niger Delta city of Port Harcourt, the study adopted a survey approach, using primary data obtained from staff of these hotels (being the population of the study). Four hypotheses were tested using Spearman’s Rank Correlation to evaluate the relationship between the operational dimensions of Supply Chain Integration (the dependent variable) and Organisational Agility (the independent variable). Results from these analyses reveal a strong correlation between the operational dimensions of Supply Chain Integration – Internal Integration and Supplier Integration – with those of Organisational Agility – Operational Flexibility and Adaptability. Going by these findings, the study concludes that Supply Chain Integration (as measured by Internal Integration and Supplier Integration) is a strong predictor of Organisational Agility, the criterion variable. The research has thus demonstrated the potential to enhance operational flexibility and adaptability by these firms in the industry while concurrently meeting customer service criteria. It is recommended herein that hospitality firms in the Niger Delta, especially four-star hotels, strive to enhance their organizational agility leveraging on supply chain integration as an essential strategic management tool for improving intra-firm communication and coordination across the critical functional domains. This could be mostly achieved through improved integration of data and information system exchange.

Authors: Chadwick Verity , Mills Georgia , Tang Catherine , Anazodo Antoinette , Dear Rachel , Rogers Rachael , Lavee Orly , Milliken Samuel , McCaughan Georgia , Hamad Nada
Published: February 2025

Background: Cancer treatment can significantly reduce reproductive potential in female patients. This study sought to explore the incidence of fertility counseling in women of childbearing potential before, during, and after anticancer therapies. Methods: We conducted a retrospective medical record review at a major Australian cancer center of premenopausal females aged 18 to 49 years diagnosed with cancer between 2017 and 2020. Results: A total of 143 patients met inclusion criteria. Of these patients, only 12.6% had a reproductive health history documented at the first consult and just more than half (58%) had a fertility preservation discussion documented with their primary hematologist or oncologist. A quarter (25.9%) saw a specialist gynecologist to discuss fertility preservation options, and 11.2% were offered a referral but declined. Conclusions: In an Australian major cancer center, only half of women with a new malignancy diagnosis had documented reproductive counseling. Promoting and facilitating reproductive counseling needs to be addressed through strengthening working relationships between fertility preservation specialists and oncologists/hematologists, implementing technology systems to ensure fertility preservation documentation, and improving staff education.

Published: February 2025

Background: Interventions to address sexual health in hematopoietic stem cell transplant (HSCT) survivors are limited. Methods: We conducted a pilot randomized trial of a digital app, SHIFT (Sexual Health and Intimacy Following Transplant), to address sexual dysfunction in HSCT survivors who were ≥3 months post autologous or allogeneic HSCT. Patients were randomly assigned to SHIFT or enhanced usual care. All participants first underwent a brief physical examination by a trained HSCT clinician. Participants assigned to the intervention received access to SHIFT for 8 weeks. SHIFT consists of 5 modules addressing the biological, interpersonal, social, and psychological causes of sexual dysfunction. The primary endpoint was feasibility, defined a priori as ≥60% enrollment of eligible patients, and 60% of those assigned to SHIFT completing ≥70% of the modules. We assessed patient satisfaction with sex, interest in sex, orgasm pleasure (using the Patient-Reported Outcomes Measurement Information System [PROMIS]), quality of life (QoL; using the Functional Assessment of Cancer Therapy – Bone Marrow Transplant [FACT-BMT]), and anxiety and depression symptoms (using the Hospital Anxiety and Depression Scale [HADS]) at baseline, 8 weeks, and 12 weeks. The preliminary effects of SHIFT on study outcomes were explored using analysis of covariance (ANCOVA) and estimates of effect size at 8 weeks (Cohen’s d). Results: We enrolled 64.2% (61/95) of eligible patients. Of those assigned to the intervention, 70.0% completed 4 of the 5 SHIFT modules and 66.7% completed all SHIFT modules. At 8 weeks, SHIFT participants reported improved satisfaction with sex (14.6 vs 12.3; d=0.46), interest in sex (6.7 vs 5.7; d=0.59), orgasm pleasure (9.7 vs 8.3; d=0.37), QoL (115.6 vs 108.3; d=0.45), and symptoms of anxiety (4.5 vs 6.4; d=0.47) and depression (3.6 vs 5.4; d=0.62) compared with the control group. Conclusions: The SHIFT digital app to address sexual dysfunction demonstrated feasibility and promising preliminary efficacy in improving sexual health outcomes, QoL, and psychological distress for HSCT survivors.

Published: February 2025

Background: It is unclear whether patients of all races and ethnicities with gastroenteropancreatic (GEP) neuroendocrine neoplasm (NEN) have equivalent incidence and cancer-specific survival. Patients and Methods: Using the California Cancer Registry, all patients with GEP-NEN in California’s large and diverse population from 1992 to 2019 were identified. Age-adjusted incidence rates (AIRs) and cancer-specific mortality (CSM) risks were compared across racial and ethnic subgroups using structural equation modeling. Results: The non-Hispanic (NH) Black population had the highest rate of diagnosis every year (AIR2019, 7.4 per 100,000; 95% CI, 6.4–8.5). The AIRs across races and ethnicities and primary sites vary, and in 2019 statistically significantly increased for stomach, small intestine, pancreatic, and rectal NEN and for only the NH White population. Risk of mortality was neutral across many races and ethnicities for many primary sites. The only statistically significant disparity was a higher CSM rate for Hispanic patients compared with NH Black patients with small intestine NEN (subdistribution hazard ratio, 1.45; 95% CI, 1.10–1.91; P=.008). Findings suggest a higher CSM among NH Black and NH White patients with rectal NEN. Disparities in who presents with GEP-NEN were revealed across racial and ethnic populations and primary sites. The NH Black population incurred the highest rate overall consistently every year. This is the first study to evaluate cancer-specific survival disparities in all GEP-NEN primary sites across the Asian American/Native Hawaiian/Pacific Islander, Hispanic, NH Black, and NH White racial and ethnic populations. Many clinical and sociodemographic measures associated with risk of mortality differed across race and ethnicities. After careful control of those imbalances, there were few racial and ethnic disparities in risk of CSM. Conclusions: There is room to improve equity in the health care system and close the gap in diagnoses for the NH Black population with all GEP-NEN and in mortality for the Hispanic population with small intestine NEN.
The Link between Physical Evidence, Customer Satisfaction and Customer Loyalty: An Empirical Analysis
Authors: Idrus Nanda Lutfiah , Yendra Yendra , Marihi La Ode
Published: February 2025

Purpose: This study aims to examine the effect of physical evidence on customer loyalty mediated by customer satisfaction at Shadow Edge Park Jayapura Cafe. The hypothesis is that customer satisfaction mediates the impact of physical evidence on customer loyalty.
Research Design and Methodology: The method used was descriptive quantitative with a survey design. Data were collected from 120 Shadow Edge Park Jayapura Cafe consumers through questionnaires. The data were analyzed using Structural Equation Modeling (SEM) with AMOS 22 software.
Findings and Discussion: The results show that physical evidence positively and significantly influences customer satisfaction, mediating this influence on customer loyalty. The findings support the Servicescapes theory, suggesting that physical elements such as interior design, cleanliness, and ambiance of the café are key factors that influence customer satisfaction and loyalty.
Implications: Café managers should focus on managing physical evidence elements to increase customer satisfaction and loyalty. Further research is needed to explore factors such as social interaction and service quality that may influence customer loyalty. Future studies could expand geographic and cultural coverage to test the consistency of these findings.

Background: Atrial fibrillation/flutter (AF/AFl) is commonly diagnosed arrhythmia, associated with increased morbidity and mortality. Therefore, we have to improve our early AF/AFl diagnostics. Several studies indicated association between conduction delay, excessive atrial ectopic beats (AEBs) and AF/AFl onset. Association with some other AEB features is less clear.
Objective: To validate the role of early AEBs from Holter-ECG in relation to documented AF/AFl events.
Methods and Results: We enrolled 14 consecutive patients (6 female, median 60.5 years) with documented AF/AFl during or within 6 months after Holter-ECG (AF-group). Control group consisted of 10 clinically similar consecutive patients (5 female, median 64.5 years), without any evidence of AF/AFl, but with comparable burden of AEBs. Holter-ECGs were examined with 3-channel Holter system (Schiller, Darwin2 software). 24-hour data were analyzed for number and/or burden (%) of: a) AF/AFl, b) AEBs, c) early-AEBs (coupling interval cut-off <530 ms), d) AEB pairs, triplets, runs, and e) bigeminy. In addition, P-wave duration (cut-off <130 ms), PQ, QRS, and QTc were measured. AF-group had higher burden of early-AEBs (p<0.03) and longer P-waves (p<0.05) than controls. In both groups, non-conducted and aberrantly-conducted early-AEBs, AEBs in bigeminy, pairs, triplets and runs were found, as-well-as no difference for PQ, QRS, and QTc (p=NS). The majority of 243 AF/AFl events started during day-time and in 83% with early-AEBs. Before AF onset, outbursts of early-AEBs were encountered in 58% of patients.
Conclusion: A higher burden of early AES in the Holter ECG and a longer P-wave duration predict the occurrence of AF/AU.

Hankel operators plus orthogonal polynomials yield combinatorial identities
Authors:   Grinnell College, Herman E. A.
Published: February 2025

A Hankel operator \( H = [h_{i+j}] \) can be factored as \( H = MM^* \), where \( M \) maps a space of \( L^2 \) functions to the corresponding moment sequences. Furthermore, a necessary and sufficient condition for a sequence to be in the range of \( M \) can be expressed in terms of an expansion in orthogonal polynomials. Combining these two results yields a wealth of combinatorial identities that incorporate both the matrix entries \( h_{i+j} \) and the coefficients of the orthogonal polynomials.
Polynomial largeness of sumsets and totally ergodic sets
Authors:   Department of Mathematics, University of Wisconsin, Madison 480 Lincoln Drive Madison, WI 53706, Fish Alexander
Published: February 2025

We prove that a sumset of a TE subset of N (these sets can be viewed as “aperiodic” sets) with a set of positive upper density intersects any polynomial sequence. For WM sets (subclass of TE sets) we prove that the intersection has lower Banach density one. In addition we obtain a generalization of the latter result to the case of several polynomials.

e consider a bivariate rational generating function
\[
F(x, y) = \frac{P(x, y)}{Q(x, y)} = \sum_{r, s \geq 0} a_{r,s} x^r y^s
\]
under the assumption that the complex algebraic curve \( \mathcal{V} \) on which \( Q \) vanishes is smooth. Formulae for the asymptotics of the coefficients \( \{a_{r,s}\} \) are derived in [PW02]. These formulae are in terms of algebraic and topological invariants of \( \mathcal{V} \), but up to now these invariants could be computed only under a minimality hypothesis, namely that the dominant saddle must lie on the boundary of the domain of convergence. In the present paper, we give an effective method for computing the topological invariants, and hence the asymptotics of {\(a_{rs}\)}, without the minimality assumption. This leads to a theoretically rigorous algorithm, whose implementation is in progress at http://www.mathemagix.org

Let \( F(x) = \sum_{\nu \in \mathbb{N}^d} F_\nu x^\nu \) be a multivariate power series with complex coefficients that converges in a neighborhood of the origin. Assume \( F = G / H \) for some functions \( G \) and \( H \) holomorphic in a neighborhood of the origin. We derive asymptotics for the coefficients \( F_{r\alpha} \) as \( r \to \infty \) with \( r\alpha \in \mathbb{N}^d \) for \( \alpha \) in a permissible subset of \( d \)-tuples of positive reals. More specifically, we give an algorithm for computing arbitrary terms of the asymptotic expansion for \( F_{r\alpha} \) when the asymptotics are controlled by a transverse multiple point of the analytic variety \( H = 0 \). This improves upon earlier work by R. Pemantle and M. C. Wilson. We have implemented our algorithm in Sage and apply it to obtain accurate numerical results for several rational combinatorial generating functions.

Let \( A \) be a subset of \( \mathbb{F}_p^n \), the \( n \)-dimensional linear space over the prime field \( \mathbb{F}_p \), of size at least \( \delta N \) (\( N = p^n \)), and let \( S_v = P^{-1}(v) \) be the level set of a homogeneous polynomial map \( P : \mathbb{F}_p^n \to \mathbb{F}_p^R \) of degree \( d \), for \( v \in \mathbb{F}_p^R \). We show that, under appropriate conditions, the set \( A \) contains at least \( c N|S| \) arithmetic progressions of length \( l \leq d \) with common difference in \( S_v \), where \( c \) is a positive constant depending on \( \delta \), \( l \), and \( P \). We also show that the conditions are generic for a class of sparse algebraic sets of density \( \approx N^{-\gamma} \).

Published: February 2025

We present in this work results on some distributions of permutation statistics of random elements of the wreath product \( G_{r,n} = C_r \wr S_n \). We consider the distribution of the descent number, the flag major index, the excedance, and the number of fixed points, over the whole group \( G_{r,n} \), or over the subclasses of derangements and involutions. We compute the mean, variance and moment generating function, and establish the asymptotic distributions of these statistics.
Counting fixed-length permutation patterns
Authors:   Department of Mathematics University of Florida Gainesville, FL, Homberger Cheyne
Published: February 2025

We consider the problem of packing fixed-length patterns into a permutation, and develop a connection between the number of large patterns and the number of bonds in a permutation. Improving upon a result of Kaplansky and Wolfowitz, we obtain exact values for the expectation and variance for the number of large patterns in a random permutation. Finally, we are able to generalize the idea of bonds to obtain results on fixed-length patterns of any size, and present a construction that maximizes the number of patterns of a fixed size.

In this paper, we generalize an earlier statistic on square-and-domino tilings by considering only those squares covering a multiple of k, where k is a fixed positive integer. We consider the distribution of this statistic jointly with the one that records the number of dominos in a tiling. We derive both finite and infinite sum expressions for the corresponding joint distribution polynomials, the first of which reduces when k = 1 to a prior result. The cases q = 0 and q = −1 are noted for general k. Finally, the case k = 2 is considered specifically, where further results may be given, including a combinatorial proof when q = −1.
