The Urban Building Community Model for Earth System Modeling: Model Formulation and Evaluation

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract A new urban canopy model is presented. Unlike the two‐dimensional (2D) canyon assumption used in most urban canopy models, this model proposes a three‐dimensional (3D) building community conceptualization. A key parameter, the building height‐to‐side‐length ratio (H/L), is introduced to replace the canyon height‐to‐width ratio (H/W) used in ...

An Eikonal‐Based Angle‐Domain Least‐Squares Kirchhoff Depth Migration in General Anisotropic Media

open access: yesGeophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Least‐squares migration (LSM) is an inversion‐based imaging method that seeks a reflectivity model whose predicted data best fit the recorded seismic data in a least‐squares sense. However, conventional LSM can be unreliable for anisotropic reflection data if reflection angles are neglected.

On the Kirchhoff index of hypergraphs

open access: yes
summary:Let $\mathcal {H}$ be a connected $k$-uniform hypergraph on $n$ vertices and $m$ hyperedges. K. Feng, W. Li (1996) introduced an adjacency matrix $\mathcal {A}(\mathcal {H})$ for hypergraphs. We consider the corresponding Laplacian matrix.

Photosynthetic Responses to Rising CO2 and Temperature: Mechanisms, Models, and Field Evidence

open access: yesGlobal Change Biology, Volume 32, Issue 9, September 2026.
This review revisits the mechanistic basis of CO2 × temperature interactions in C3 photosynthesis and evaluates how subsequent research has refined this framework. We synthesize evidence showing how acclimation, diffusive limitations, and canopy processes modify photosynthetic responses to rising CO2 and warming across scales.

Combinatorial Designs with Two Singular Values I. Uniform Multiplicative Designs [PDF]

open access: yes
In this and a sequel paper [10] we study combinatorial designs whose incidence matrix has two distinct singular values.These generalize 2-(v, k, É) designs, and include partial geometric designs and uniform multiplicative designs.Here we study the latter,
