Branch-depth: Generalizing tree-depth of graphs [PDF]
European J. Combin., 90(December 2020), 103186, 2019 We present a concept called the branch-depth of a connectivity function, that generalizes the tree-depth of graphs. Then we prove two theorems showing that this concept aligns closely with the notions of tree-depth and shrub-depth of graphs as follows.

Characterization and Inverse Design of Stochastic Mechanical Metamaterials Using Neural Operators
Advanced Materials, EarlyView.This study presents a DeepONet‐based machine learning framework for designing stochastic mechanical metamaterials with tailored nonlinear mechanical properties. By leveraging sparse but high‐quality experimental data from in situ micro‐mechanical tests, high predictive accuracy and enable efficient inverse design are achieved.

Pseudo-finiteness of arbitrary graphs of bounded shrub-depth [PDF]
arXiv, 2022 We consider classes of arbitrary (finite or infinite) graphs of bounded shrub-depth, specifically the classes $\mathrm{TM}_r(d)$ of arbitrary graphs that have tree models of height $d$ and $r$ labels. We show that the graphs of $\mathrm{TM}_r(d)$ are $\mathrm{MSO}$-pseudo-finite relative to the class $\mathrm{TM}^{\text{f}}_r(d)$ of finite graphs of ...

Bird Population Changes Following the Establishment of a Diverse Stand of Woody Plants in a Former Crop Field in North Dakota, 1975– 2015 [PDF]
, 2018 Changes in the coverage of trees and shrubs on the North Dakota landscape since Euro- American settlement have likely had a pronounced impact on bird species that favor woody vegetation.

Advanced Science, EarlyView.Japanese encephalitis virus (JEV) employs a cap‐independent (CI) translation strategy to evade host translational shutoff. During the shut‐off of host cellular canonical translation, DEAD‐box protein 3 (DDX3) bind to JEV UTRs to establish a closed‐loop architecture, and its interaction with poly(A)‐binding protein 1 (PABP1) to form DDX3/PABP1/eIF4G ...

Extreme fire severity interacts with seed traits to moderate post‐fire species assemblages
American Journal of Botany, EarlyView.Abstract Premise Climate change is globally pushing fire regimes to new extremes, with unprecedented large‐scale severe fires. Persistent soil seed banks are a key mechanism for plant species recovery after fires, but extreme fire severity may generate soil temperatures beyond thresholds seeds are adapted to.

Shading contributes to Sphagnum decline in response to warming
Ecology and Evolution, 2023 Experimental warming of an ombrotrophic bog in northern Minnesota has caused a rapid decline in the productivity and areal cover of Sphagnum mosses, affecting whole‐ecosystem carbon balance and biogeochemistry.
