Mathematical modeling and data & Survey
No full textThis research examines brand loyalty and team identification among fans of National Football League (NFL) teams and how loyalty to football, NFL teams and athletes is impacted by the changing dynamics of the fanbase. Brand loyalty in sports is complex and fan attachment to their teams often provoke intense emotional responses. The research employed a Likert-type survey questionnaire pre- and post-test and an emotional response pictorial assessment using Self-Assessment Manakin (SAM) to measure emotional dimensions. Descriptive and parametric statistics were used to measure the relationships between NFL team loyalty (team commitment and team identification), emotional response (pleasure-arousal-dominance) and team and player social activist behaviors. The research also assesses the relationships between demographic and background and team and player activist behaviors to determine changes in fan dynamics. The findings show moderate positive relationships between team loyalty, team and player activist behaviors, younger age and middle income.

Continuously variable topological charge of a vector vortex beam generated by an integrated metasurface
No full textWe propose and numerically verify a new method for generating a vector vortex beam, in which the twist of the wavefront varies continuously along the beam axis, offering potential benefits for distance detection
Generation of longitudinally varying vector vortex beams using dielectric metasurfaces
No full textWe numerically demonstrate the generation of vector vortex beams using dielectric metasurfaces, where the beams' topological features evolve longitudinally during propagation. This distinctive characteristic, along with the ability to control it, could enable new applications in remote sensing for topological light
Melting Enhancement of Phase Change Material with Fins and Graphene Nanoplatelets Under Micro/Low Gravity for Thermal Management in Space Detector
No full textThermal energy storage is an efficient way for thermal control of near-earth and deep space detectors, but the melting rate is restricted by low heat transfer performance of phase change material (PCM) and disappearance or suppression of natural convection under micro/low gravity. To accelerate melting of PCM under micro/low gravity, graphene nanoplatelet (GNP)-enhanced PCM with fins are proposed. The effects of fin shape, GNP concentration and gravity level on dynamic melting characteristics considering thermocapillary convection are investigated. The results show that the improvement effect of rectangular fins on melting rate is higher than that of triangular fins under microgravity; with the decrease of gravity level, the melting rate is reduced. The presence of GNP significantly promotes the melting under micro/low gravity. At GNP concentration of 0.03 vol%, the reduction of melting time can reach 58.2%, 49.4% and 51.6% at microgravity, moon's gravity of 1.625 m s-2 and Mars' gravity of 3.711 m s-2, respectively

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Rh-Catalyzed Reagent-Free Ring Expansion of Cyclobutenones and Benzocyclobutenones
No full textHere we report a reagent-free rhodium-catalyzed ring-expansion reaction via C-C cleavage of cyclobutenones. A variety of poly-substituted cyclopentenones and 1-indanones can be synthesized from simple cyclobutenones and benzocyclobutenones. The reaction condition is near pH neutral without additional oxidants or reductants. The potential for developing a dynamic kinetic asymmetric transformation of this reaction has also been demonstrated. Further study supports the proposed pathway involving Rh-insertion into the cyclobutenone C-C bond, followed by beta-hydrogen elimination, olefin insertion and reductive elimination.CPRIT R 1118NIGMS R01GM109054-01Welch Foundation F 1781Chemistr
