Algebraic properties of the binomial edge ideal of a complete bipartite graph
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014 Let JG denote the binomial edge ideal of a connected undirected graph on n vertices. This is the ideal generated by the binomials xiyj − xjyi, 1 ≤ i < j≤ n, in the polynomial ring S = K[x1, . . . , xn, y1, . . . , yn] where {i, j} is an edge of G.

Fitting the Fractional Polynomial Model to Non-Gaussian Longitudinal Data
Frontiers in Psychology, 2017 As in cross sectional studies, longitudinal studies involve non-Gaussian data such as binomial, Poisson, gamma, and inverse-Gaussian distributions, and multivariate exponential families. A number of statistical tools have thus been developed to deal with

Some Algebraic Aspects of Morse Code Sequences [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 Morse code sequences are very useful to give combinatorial interpretations of various properties of Fibonacci numbers. In this note we study some algebraic and combinatorial aspects of Morse code sequences and obtain several q-analogues of Fibonacci ...

Half a century of echinoid population decline in the northern Gulf of Aqaba, Red Sea
Journal of Animal Ecology, EarlyView.Multi‐decadal monitoring in the Gulf of Aqaba, northern Red Sea, reveals severe (>90%) declines of key echinoid grazers. These declines signify a collapse of crucial herbivory functions underpinning coral reef resilience. Results implicate accelerating anthropogenic stress as a principal driver, emphasizing the urgent need for sustained, species ...

Health Services Research, EarlyView.ABSTRACT Objective To estimate changes in lung cancer screening at age 65, the age of nearly universal Medicare coverage. Study Setting and Design Screening reduces lung cancer mortality but is underutilized. We used a regression discontinuity design to measure the impact of nearly universal Medicare coverage at age 65 on first‐time receipt of ...

Methods in Ecology and Evolution, EarlyView.Abstract Passive acoustic telemetry systems are widely deployed to track animals in aquatic environments. However, investments in integrative methods of data analysis have remained comparatively limited, with current workflows typically considering individual movements separately from space use, home ranges and residency.

Animal Conservation, EarlyView.Identifying the most effective criterion to assess the conservation status of vulnerable species in threatened tropical regions is crucial to evaluate recovery plans. We investigated the influence of environmental heterogeneity on the extent of occurrence (EOO), area of occupied habitat (AOH), and density variation of two Amazonian riparian frog ...
