Predicting The Peak Bloom Of Yoshino Cherry Blossoms In Washington, Dc With Random Forest Regression, James Watkins, Ian Forde, Rene Salinas Jan 2026

Predicting The Peak Bloom Of Yoshino Cherry Blossoms In Washington, Dc With Random Forest Regression, James Watkins, Ian Forde, Rene Salinas

Spora: A Journal of Biomathematics

Springtime ushers in a bouquet of flowering arrangements that create ripe economic and social opportunities. Since the Japanese ambassador's gift of 3020 Yoshino cherry trees to the National Mall in Washington, DC, the National Cherry Blossom Festival has occurred annually beginning in 1935. This festival is unique in that over one million visitors parade the Capitol area each year, drawing inspiration from the peak blooming date of the characteristic cherry trees. The NPS provided data on the several stages of Yoshino cherry trees leading to peak bloom from 2004–2024, while local climate data exists for temperature, rainfall, and other factors …

Decoding Early Covid-19 Responses Using Mathematical Modeling Of Social Distancing Strategies Across Multiple Countries, Sri Gunturu, Suki Lewis, Katelyn Nguyen, Asma Azizi Jan 2026

Decoding Early Covid-19 Responses Using Mathematical Modeling Of Social Distancing Strategies Across Multiple Countries, Sri Gunturu, Suki Lewis, Katelyn Nguyen, Asma Azizi

Spora: A Journal of Biomathematics

During the early phase of the COVID-19 pandemic, before vaccines were available, countries implemented diverse combinations of social-distancing (SD) measures shaped by cultural norms and public acceptance. These differences produced varied outcomes in controlling viral spread, offering lessons for future health-crisis preparedness. We performed a reverse-engineering analysis of early COVID-19 case data from five socioculturally distinct countries—India, Vietnam, Italy, Finland, and the United States—selected to capture a range of initial prevalence levels. Using mathematical modeling and data fitting, we inferred the relative contributions of three SD interventions: face masking, quarantine, and isolation of infected individuals. We then employed an efficiency …

Optimal Intervention Strategies In Age-Structured Sirvd Model: Epidemiological And Economic Analysis Of Covid-19 In Korea, Joon Chun, Melisa Hendrata Jan 2026

Optimal Intervention Strategies In Age-Structured Sirvd Model: Epidemiological And Economic Analysis Of Covid-19 In Korea, Joon Chun, Melisa Hendrata

Spora: A Journal of Biomathematics

This study employed an age-structured Susceptible-Infected-Recovered-Vaccinated-Deceased (SIRVD) model to design optimal COVID‑19 intervention strategies by integrating epidemiological dynamics with economic costs. Using empirical data from South Korea, we estimated transmission parameters and analyzed quarantine-based non-pharmaceutical interventions (NPIs) alongside targeted vaccination scenarios. Our results indicated that a stronger form of mild NPI (upper range of Level I), when combined with targeted vaccination that prioritized seniors, achieved substantial reductions in infection peaks and overall economic burden. These findings underscore the effectiveness of age-specific strategies in epidemic management and offer critical insights for policymakers seeking balanced, resource-efficient approaches.

Inhomogeneous Branching Random Walks: Incorporating Genealogy And Density Effects, Lauren Ajax, Beatrice Durham, Pratima Hebbar, Cade Johnston, Jiayi Zhang Jan 2026

Inhomogeneous Branching Random Walks: Incorporating Genealogy And Density Effects, Lauren Ajax, Beatrice Durham, Pratima Hebbar, Cade Johnston, Jiayi Zhang

Spora: A Journal of Biomathematics

We introduce a novel framework using inhomogeneous branching random walks (BRWs) to model biological processes, specifically by introducing genealogy-dependence in branching rates and displacement distributions to model bacterial colony growth. Current stochastic models often either assume independent and identical behavior of individual agents or incorporate only spatiotemporal inhomogeneity, ignoring the effect of genealogy-based inhomogeneity on the long-time behavior of these processes. Such asymptotics are of independent mathematical interest and are crucial in understanding the emergence of patterns. We propose several inhomogeneous BRW models in 2D space where displacement distributions and branching rates vary with time, space, and genealogy. A combined …

Agha, Jantson Hoh, Abdulmutalib Alabeed Allaq, Amjad Abdulhadi Mohammed, Muneer Mohammed Saleh Alsayadi

AUIQ Complementary Biological System

Mesenchymal stem cells (MSCs) are widely used in regenerative medicine due to their self-renewal capacity, multilineage differentiation potential, and paracrine activity. Limitations associated with the sourcing and scalability of human MSCs have increased interest in xenogeneic alternatives, particularly sheep umbilical cord–derived MSCs (sUC-MSCs). These cells display high proliferative capacity, stable karyotypes, and a typical MSC immunophenotype (CD44, CD73, CD90, CD105), with low basal immunogenicity. sUC-MSCs exhibit osteogenic, chondrogenic, and adipogenic differentiation potential and secrete angiogenic and immunomodulatory factors, including VEGF, HGF, IGF-1, TGF-β, and IL-10. Owing to their biological similarities to human MSCs and accessibility from perinatal tissue, …

Strategic Distribution, Digital Marketing, And Open Innovation: Toward Integrated Capability Development For Sme Performance, Johannes Baptista Halik, Maria Yessica Halik, Septin Basongan, Jhoel Mapau

Asia Marketing Journal

This study examines the impact of Distribution Strategy on SME performance, with Digital Marketing and Open Innovation as mediating variables. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), data were analyzed from 250 SMEs in Makassar, Indonesia. The results show that Distribution Strategy positively affects performance, both directly and indirectly through Open Innovation. However, Digital Marketing does not serve as a significant mediator, indicating that its use among SMEs may still be limited to tactical functions. Open Innovation emerges as the strongest contributor, highlighting its role in converting distribution capabilities into performance gains. The study enriches Resource Advantage (R-A) Theory …

Mitigating Appearance Threats: The Differential Effects Of Compensatory Consumption On Self-Control, Yi-Seo Jo, Eunice Eun-Sil Kim Jan 2026

Mitigating Appearance Threats: The Differential Effects Of Compensatory Consumption On Self-Control, Yi-Seo Jo, Eunice Eun-Sil Kim

Asia Marketing Journal

Appearance threats, arising from gaps between one’s appearance and societal beauty standards, weaken self-control the capacity to favor long-term goals over immediate impulses. This research explores how compensatory consumption mitigates these effects, focusing on type (within-domain vs. across-domain) and timing (near-future vs. distant-future) across two studies. Rooted in symbolic self-completion and construal level theories, Study 1 examines how compensation type affects self-control under appearance threats, with rumination as a mediator. Findings show across-domain compensation sustains self-control by diverting focus from appearance concerns, unlike within-domain compensation, which heightens rumination and impairs self-regulation. Study 2 investigates how compensation timing moderates these outcomes, …

When And Why Managerial Responseswork: A Dual-Process Model Of Linguistic Cues, Review Rating, And Usefulness, Jungwon Lee, Cheol Park Jan 2026

When And Why Managerial Responseswork: A Dual-Process Model Of Linguistic Cues, Review Rating, And Usefulness, Jungwon Lee, Cheol Park

Asia Marketing Journal

This research develops and empirically tests a contingency model explaining how specific linguistic characteristics of a firm's response to an online review influence the review's usefulness. We argue that the diagnostic value of different linguistic cues is contingent upon the reader's information processing mode-systematic versus heuristic-which is triggered by the valence of the original review's rating. An econometric analysis of 41,704 review-response dyads from TripAdvisor reveals that a conceptual cue (personalization, operationalized as topical relevance) and a perceptual cue (readability) both significantly increase review usefulness. In contrast, another perceptual cue (Linguistic Style Matching) decreases usefulness, a finding we interpret as …

“It’S A Dupe, Not A Counterfeit!” An Exploration Of Motives For Dupe Consumption Motives, Jungyong Ahn

Asia Marketing Journal

This study was designed to explore consumer motives for dupe consumption and to measure the influence of these identified motives on consumer satisfaction with dupe products and intention to sharing dupe products. Through a literature review and in-depth interviews, five key consumer motives were anticipated: (1) self-protection, (2) saving money, (3) anti-materialism, (4) mimicry, and (5) enjoyment. Corresponding measurement items were developed to assess these motives. A factor analysis conducted on survey data collected from 300 respondents successfully confirmed the extraction of these five motives as expected. Moreover, regression analysis further demonstrated the statistically significant positive impact of these motives …

How Does A Consumer’S Anticipated Happiness Influence Participation In Value Co-Creation? : Focusing On Definition Of Happiness, Minsik Cho, Suna La Jan 2026

How Does A Consumer’S Anticipated Happiness Influence Participation In Value Co-Creation? : Focusing On Definition Of Happiness, Minsik Cho, Suna La

Asia Marketing Journal

Value co-creation (VCC) is essential for a new product development, transforming ideas into collaboratively created value-in-use, particularly under Service-Dominant Logic (S-D Logic). Recognizing that consumers engage in VCC with the goal of achieving happiness, this study investigates how anticipated happiness—arising from affective forecasting of VCC experiences—encourages customers’ participation in high-technology VCC initiatives. It also examines how individuals’ definitions of happiness—calmness vs. excitement—influence this process in VCC, using a validated temporal focus manipulation to induce these differing happiness orientations. Results indicate that future-focused individuals tend to define their happiness as excitement, while present-focused individuals associate it with calmness. Then, definitions of …

The Impact Of Sense Of Power On Consumer Click-Through Intention Under Ai Personalized Recommendation, Li Li, Dhakir Abbas Ali Jan 2026

The Impact Of Sense Of Power On Consumer Click-Through Intention Under Ai Personalized Recommendation, Li Li, Dhakir Abbas Ali

Asia Marketing Journal

This study investigates how consumers' sense of power influences their click-through intentions in AI-driven personalized recommendation systems. While prior research has explored personalized marketings impact on consumer behavior, the role of perceived power remains understudied. Through scenario-based experiments, we find that a heightened sense of power enhances engagement with AI recommendations, with self-efficacy as a key mediator. However, this effect weakens when privacy concerns are high, highlighting privacy as a critical moderating factor. Specifically, empowered consumers are more likely to interact with AI recommendations, but only when privacy risks are minimal. These findings deepen our understanding of consumer-AI interactions, emphasizing …

Blockchain-Based Peer-To-Peer Renewable Energy Trading And Traceability Of Transmission And Distribution Losses, Amit Kumar Vishwakarma, Pratyush Kumar Patro, Adolf Acquaye, Raja Jayaraman, Khaled Salah Jan 2026

Blockchain-Based Peer-To-Peer Renewable Energy Trading And Traceability Of Transmission And Distribution Losses, Amit Kumar Vishwakarma, Pratyush Kumar Patro, Adolf Acquaye, Raja Jayaraman, Khaled Salah

Industrial Engineering: Faculty & Staff Publications

In attempts to progress the transition towards decarbonizing energy systems and achieving sustainable development goals linked to energy, renewable energy sources (RES), which are decentrally deployed, are being widely promoted. However, RES are constrained by many barriers, some of which are technical in nature, such as energy losses. For instance, traditional peer-to-peer (P2P) trading systems have been used as a mechanism to advance RES because they offer a promising solution for decentralized energy trading without third-party intermediaries. However, it faces significant challenges, notably in accounting for energy losses during transmission and distribution, thus reducing overall system efficiency. We propose an …

Retroactive Eligibility Waivers: Innovative Or Ineffective?, Mohamed Kacem Benyamine Jan 2026

Retroactive Eligibility Waivers: Innovative Or Ineffective?, Mohamed Kacem Benyamine

Theses and Dissertations

Medicaid’s retroactive eligibility provision covers medical expenses for beneficiaries up to 90 days before the application date. Retroactive eligibility insulates uninsured, low-income households from expensive healthcare emergencies. New Hampshire, Arkansas, and Iowa recently obtained waivers to end retroactive coverage. Using a difference-in-differences design and data from the Behavioral Risk Factor Surveillance System, I evaluate whether changes in retroactive coverage affect enrollment rates and self-reported health. Removing retroactive eligibility has no statistically significant effects on insurance enrollment or self-reported health. However, it does increase rates of access to a doctor by 1.0% overall and by 1.6% for women. Removing retroactive eligibility …
