Three‐dimensional meso‐scale finite element modeling of recycled aggregate concrete using cohesive zone method

open access: yesStructural Concrete, EarlyView.
Abstract The presence of adhered mortar (AM) in recycled aggregates (RAs) significantly affects the mechanical performance of recycled aggregate concrete (RAC). Meso‐scale modeling provides valuable insights into complex phase interactions, enabling a better understanding of RAC behavior.

On α-uniformly close-to-convex and quasi-convex functions with negative coefficients

open access: yes, 2020
In this paper we study a class of α-uniformly starlike functions with negative coefficients, a class of α-uniformly convex functions with negative coefficients, a class of α-uniformly close-to-convex functions with negative coefficients and a class of ...

Camera trap distance sampling for density estimation of tiger prey in a Sumatran ecosystem restoration concession

open access: yesWildlife Biology, EarlyView.
Estimating prey species densities is critical for implementing effective tiger Panthera tigris recovery strategies. Several statistical models exist for density estimation of unmarked species from camera trap data, all of which rely on the random placement of cameras.

On the Consistency of Approximate Maximizing Estimator Sequences in the Case of Quasiconcave Functions [PDF]

open access: yes
This paper demonstrates consistency for estimators obtained by approximately maximizing a sequence of stochastic quasiconcave functions on RP that converges in probability pointwise to a non-stochastic function.

Micro‐Mechanism Informed Neural Networks for Process‐Property Prediction in Laser Powder Bed Fusion

open access: yesArtificial Intelligence for Engineering, EarlyView.
Hard physics embedding, where neural networks learn residuals relative to analytical baselines, substantially outperforms soft loss‐function constraints for extrapolation in LPBF process–property prediction. Physics integration architecture determines generalization capability more than constraint quantity.

Fault‐Tolerant Fuzzy Boundary Control for Nonlinear Distributed Parameter Systems Under Limited Measurements and Markovian Failures

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This paper proposes a boundary control method for nonlinear distributed parameter systems (DPSs) with limited boundary measurements (BMs), as typically encountered in networked cyber‐physical processes with spatially distributed dynamics such as thermal and biomedical diffusion systems.

A unified analytical framework for Mössbauer synchrotron sources

open access: yesJournal of Synchrotron Radiation, EarlyView.
We present a unified analytical framework for Mössbauer synchrotron and X‐ray free‐electron laser sources that provides exact, rotationally invariant expressions for resonance energies and transition probabilities in mixed magnetic dipole–electric quadrupole interactions without Hamiltonian diagonalization.

Facilitation influences when trees grow, but not growth rate in a dry temperate forest

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Accurately predicting the role of forests in the global carbon cycle requires a detailed understanding of the factors mediating the timing and magnitude of radial stem growth. While weather conditions and topo‐edaphic factors play a critical role in mediating short‐term
