The asymptotic distributions of the largest entries of sample correlation matrices

, 2004
Let X_n=(x_{ij}) be an n by p data matrix, where the n rows form a random sample of size n from a certain p-dimensional population distribution. Let R_n=(\rho_{ij}) be the p\times p sample correlation matrix of X_n; that is, the entry \rho_{ij} is the ...

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

Nordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Machine‐learning approaches for characterizing the raindrop size distributions in Western Pacific tropical cyclones

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Long‐term disdrometer observations are utilized to derive Z–R relationships for ‐the Western Pacific tropical cyclones. A hybrid moment‐based approach is employed to determine the interrelationships among pairs of gamma distribution parameters. Enhanced estimates of rainfall rate and slope parameter are obtained using machine‐learning techniques ...

Probabilistic Extensions of the Erd\H os-Ko-Rado Property

, 2005
The classical Erd\H os-Ko-Rado (EKR) Theorem states that if we choose a family of subsets, each of size (k), from a fixed set of size (n (n > 2k)), then the largest possible pairwise intersecting family has size (t ={n-1\choose k-1}).

Psychological Resilience to Climate Change: The Role of Self‐Efficacy, Mindfulness, Perceived Nature Restorativeness, and Subjective Well‐Being

Sustainable Development, EarlyView.
ABSTRACT The current study presents a causal model of climate‐induced psychological resilience by assessing the impact of dispositional mindfulness, self‐efficacy beliefs, and perceived restorativeness of nature. It further examines the associations among climate change coping strategies, subjective well‐being components, eco‐emotions, and resilience ...

Translated Poisson Approximation to Equilibrium Distributions of Markov Population Processes [PDF]

, 2018
The paper is concerned with the equilibrium distributions of continuous-time density dependent Markov processes on the integers. These distributions are known typically to be approximately normal, with $O( 1 /{\sqrt{n}})$ error as measured in Kolmogorov ...

The Nexus Between Circular Economy and Sustainable Supply Chain Management: PRISMA Methodology

Sustainable Development, EarlyView.
ABSTRACT The intersection of sustainable supply chain management (SSCM) and circular economy (CE) has attracted increasing academic and practical attention, emphasizing the need for integrated sustainability approaches. This study employs the PRISMA protocol and conceptualizes the CE–SSCM relationship as a dynamic system in which internal capabilities,

Critical evaluation of three cryo‐EM structures of particulate methane monooxygenase by quantum refinement

Acta Crystallographica Section D, EarlyView.
We have studied the copper sites in three cryogenic electron‐microscopy structures of particulate methane monooxygenase with quantum refinement. We show that the CuA, CuC and CuD sites are correctly modelled and that the CuB site is mononuclear in all structures, whereas we find no support for copper in the suggested trinuclear active site or two sites

Stein's method, Palm theory and Poisson process approximation

, 2004
The framework of Stein's method for Poisson process approximation is presented from the point of view of Palm theory, which is used to construct Stein identities and define local dependence.
