Bayesian clustering of multivariate extremes

Canadian Journal of Statistics, EarlyView.
Abstract The asymptotic dependence structure between multivariate extreme values is fully characterized by their projections on the unit simplex. Under mild conditions, the only constraint on the resulting distributions is that their marginal means must be equal, which results in a nonparametric model that can be difficult to use in applications ...

On Markov Chains with Uncertain Data [PDF]

In this paper, a general method is described to determine uncertainty intervals for performance measures of Markov chains given an uncertainty region for the parameters of the Markov chains.

Path decompositions for Markov chains

, 2004
We present two path decompositions of Markov chains (with general state space) by means of harmonic functions, which are dual to each other. They can be seen as a generalization of Williams' decomposition of a Brownian motion with drift.

When Dihedral Angles Mask Denticity in Molecular Conductance

ChemPhysChem, EarlyView.
This study tests whether higher molecule–electrode denticity increases conductance in single‐molecule junctions. Using nonequilibrium Green's function technique in conjunction with density functional theory simulations and mechanically controlled break‐junction experiments on a tetradentate N‐heterohexacene, it is found that conductance depends mainly ...

Straight to Phase III: Model‐Informed Approach Speeds Depemokimab Clinical Development in Interleukin‐5‐Driven Diseases

Clinical Pharmacology &Therapeutics, EarlyView.
Straight to Phase III: Model‐informed approach speeds depemokimab clinical development in interleukin‐5‐driven diseases. IL‐5, a key mediator of type 2 inflammation, underlies various diseases, including severe asthma, CRSwNP, EGPA, and HES. Reduction in blood eosinophil count (BEC), a biomarker of IL‐5 activity, is commonly used to evaluate the ...

TimeFlow 2: An Unsupervised Cell Lineage Detection Method for Flow Cytometry Data

Cytometry Part A, EarlyView.
TimeFlow 2 is a new method for cell lineage inference in flow cytometry data. It constructs cell state paths along pseudotime and aggregates them into biologically informative groups. It allows tracking of cytometry markers within each automatically inferred lineage.

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

Ecography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Dependent Discrete Risk Processes - Calculation of the Probability of Ruin

Operations Research and Decisions, 2010
This paper is devoted to discrete processes of dependent risks. The random variables describing the time between claims can be dependent in such processes, unlike under the classical approach.

Twenty years of dynamic occupancy models: a review of applications and look to the future

Ecography, EarlyView.
Since their introduction over 20 years ago, dynamic occupancy models (DOMs) have become a powerful and flexible framework for estimating species occupancy across space and time while accounting for imperfect detection. As their popularity has increased and extensions have further expanded their capabilities, DOMs have been applied to increasingly ...

Application of Markov chain and entropy analysis to lithologic succession — an example from the early Permian Barakar Formation, Bellampalli coalfield, Andhra Pradesh, India

Journal of Earth System Science, 2009
A statistical approach by a modified Markov process model and entropy function is used to prove that the early Permian Barakar Formation of the Bellampalli coalfield developed distinct cyclicities during deposition. From results, the transition path of lithological states typical for the Bellampalli basin is as: coarse to medium-grained sandstone ...
