The Spatial Distribution of Tree Dieback Affected by Mistletoe in Relation to their Crown Characteristics [PDF]

جغرافیا و پایداری محیط, 2016
1- Introduction One of the main problems in The Zagros Forests is oak trees dieback. What is really certain and important is the fact that the tree dieback crisis caused the declining of oak in oak forest of Zagros. Oak decline is characterized by crown

Variational and Monte Carlo Methods for Bayesian Inversion of Dynamic Subsurface Flow Simulations Using Seismic and Fluid Pressure Data

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract In order to predict future performance of subsurface fluid reservoirs under possible operating scenarios, a dynamic, porous‐medium flow simulation model must be tuned to include representative properties of the reservoir. Estimating subsurface reservoir properties given remotely sensed or borehole‐based observations typically involves finding ...

How Variable Are Cold Pools?

Geophysical Research Letters
Cold pools formed by precipitating convective clouds are an important source of mesoscale temperature variability. However, their sub‐mesoscale (100 m–10 km) structure has not been quantified, impeding validation of numerical models and understanding of ...

OccuGAMs: Non‐linear occupancy and abundance modelling with imperfect detection

Methods in Ecology and Evolution, Volume 17, Issue 3, Page 929-946, March 2026.
Abstract Hierarchical occupancy and abundance models (HOAMs) have become a leading approach for inferring wildlife population dynamics because they explicitly account for imperfect detection. HOAMs are suitable for sampling approaches that produce detection histories from repeated visits to the same sites, including direct observations (e.g. bird point

Spatial Autocorrelation of Species Diversity and Distributions in Time and Across Spatial Scales

Global Ecology and Biogeography, Volume 35, Issue 3, March 2026.
ABSTRACT Aim Spatial autocorrelation (SAC), also known as aggregation or clumping, reflects species niche and dispersal, has conservation significance, and affects ecological models. Yet, we know little about the spatial and temporal patterns of SAC in empirical data.

Heat Transfer in Nuclear Waste Glasses: Measurements and Modeling of Thermal Radiation Properties

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
ABSTRACT We measured and modeled near‐infrared extinction of nuclear waste glasses from 300°C to 1150°C to enable predictive radiation heat transfer and thermal conductivity estimates. A composition‐ and redox‐informed model resolved contributions from key chromophores (Fe+2‐O‐Fe+3, V+4, free and bonded ≡Si‐OH groups) and, when present, spinel ...

Properties of the intrinsically stationary stochastic processes

Журнал Белорусского государственного университета: Математика, информатика, 2017
Intrinsically stationary random processes with continuous time are investigated. Their connections with second-order stationary processes and processes with the second-order stationary increments are studied.
