A note on the multitype measure branching process [PDF]

Advances in Applied Probability, 1992
The existence of a class of multitype measure branching processes is deduced from a single-type model introduced by Li [8], which extends the work of Gorostiza and Lopez-Mimbela [5] and shows that the study of a multitype process can sometimes be reduced to that of a single-type one.

Detecting Changes in Space‐Varying Parameters of Local Poisson Point Processes

Environmetrics, Volume 36, Issue 5, July 2025.
ABSTRACT Recent advances in local models for point processes have highlighted the need for flexible methodologies to account for the spatial heterogeneity of external covariates influencing process intensity. In this work, we introduce tessellated spatial regression, a novel framework that extends segmented regression models to spatial point processes,

The simple harmonic urn

, 2011
We study a generalized Polya urn model with two types of ball. If the drawn ball is red it is replaced together with a black ball, but if the drawn ball is black it is replaced and a red ball is thrown out of the urn.

Automated seismic event detection considering faulty data interference using deep learning and Bayesian fusion

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 14, Page 1910-1931, 3 June 2025.
Abstract Structural health monitoring (SHM) aims to assess civil infrastructures' performance and ensure safety. Automated detection of in situ events of interest, such as earthquakes, from extensive continuous monitoring data, is important to ensure the timeliness of subsequent data analysis.

Multitype branching processes in random environments [PDF]

Journal of Applied Probability, 1971
Consider the classical Galton-Watson process described by Harris ((1963), Chapter 1). Recently this model has been generalized in Smith (1968), Smith and Wilkinson (1969), and Wilkinson (1967). They removed the restrictive assumption that the particles always divide in accordance with the same p.g.f.

Using a Plant Hydrodynamic Model, FETCH4, to Supplement Measurements and Characterize Hydraulic Traits in a Mixed Temperate Forest

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 4, April 2025.
Abstract Species‐specific hydraulic traits play an important role in ecosystem response to water stress; however, representation of biodiverse forest canopies remains a challenge in land surface models. We introduce FETCH4, a multispecies, canopy‐level, hydrodynamic model, which builds upon previous versions of the finite‐difference ecosystem‐scale ...

The role of drones in disaster response: A literature review of operations research applications

International Transactions in Operational Research, Volume 32, Issue 2, Page 545-589, March 2025.
Abstract The increasing use of drones has led to growing interest in their potential applications in disaster response. In this study, we examine the role of drones in disaster management under three categories of operation types, which are information collection, delivery, and communication network recovery.

Moment formulas for multitype continuous state and continuous time branching processes with immigration [PDF]

, 2016
Recursions for moments of multitype continuous state and continuous time branching process with immigration are derived. It turns out that the kth (mixed) moments and the kth (mixed) central moments are polynomials of the initial value of the process ...

Dynamics and Control of Sugarcane Smut Using Deterministic and Stochastic Epidemic Models

Natural Resource Modeling, Volume 38, Issue 1, February 2025.
ABSTRACT Sugarcane smut disease is a serious issue for farmers as it can greatly reduce sugarcane yield. It is important to manage this disease effectively to prevent economic losses. Farmers can use resistant varieties of sugarcane, remove diseased plants manually, or apply appropriate fungicides to control the spread of the disease; however, the ...
