Symplecticity‐Preserving Prediction of Parameter‐Dependent Hamiltonian Dynamics by Generalized Kernel Interpolation

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT We extend the kernel‐based symplectic predictor introduced by Herkert et al. (2026) to a parameter‐augmented setting in which the learned flow‐map surrogate depends not only on the state, but also on additional variables such as physical parameters and macro time‐step sizes. The method uses a product kernel ansatz on a parameter and macro step

Multiple ortho‐mosaicking software pipelines produce comparable imagery‐derived wheat phenotypes

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Unmanned aerial systems (UAS) equipped with multispectral and RGB sensors offer valuable data for monitoring crop health and assessing disease severity. However, the wide range of available photogrammetric software complicates software selection for high‐throughput plant phenotyping.

A Gaussian Mixture Model for Multiple Instance Learning With Both Bag‐ and Instance‐Level Features

Stat, Volume 15, Issue 4, December 2026.
ABSTRACT The core challenge of multiple instance learning (MIL) is to predict bag‐level labels with partially or completely unobserved instance‐level labels. Most existing methods focus on instance‐level features and ignore commonly available bag‐level covariates. To address this issue, this paper proposes a novel Gaussian mixture model (GMM) framework

A Geometric Multigrid Preconditioner for Discontinuous Galerkin Shifted Boundary Method

International Journal for Numerical Methods in Engineering, Volume 127, Issue 21, 15 November 2026.
ABSTRACT I introduce a geometric multigrid preconditioner for the Shifted Boundary Method (SBM) designed to solve PDEs on complex geometries. While the SBM simplifies mesh generation by using a nonconforming background grid, it often results in nonsymmetric linear systems, a complete analysis of which is missing from the literature, especially with ...

Arboreality in Wild Western Lowland Gorillas (G. g. gorilla) at the Mondika Research Center, Republic of Congo

American Journal of Primatology, Volume 88, Issue 11, November 2026.
A group of western gorillas at Mondika Research Center, Republic of Congo, shifted toward lower tree strata and consumed more fruit and flowers as fruit availability increased. During low‐fruit periods, gorillas used higher strata more frequently and relied more heavily on leaves and bark.
