Topology Optimization in Civil Engineering − On the Consideration of Concrete Failure Characteristic and Self‐Weight

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT The mechanical efficiency of civil engineering structures is a key factor in the sustainable transformation of the building sector. This study presents topology optimization in civil engineering design. The static load profile of civil engineering structures is typically dominated by their self‐weight, which introduces, as a special ...

Evaluation of combined root exudate and rhizosphere microbiota sampling approaches to elucidate plant–soil–microbe interactions

New Phytologist, Volume 250, Issue 6, Page 4077-4092, June 2026.
Summary Deciphering the root exudate‐driven interplay between plants and the rhizosphere microbiota is essential for understanding plant adaptation to the environment and future‐proofing crop production. However, sampling root exudates and rhizosphere soil remains challenging due to the low throughput and destructive nature of the process.

Prescribing the nodal set of the first eigenfunction in each conformal class [PDF]

, 2015
We consider the problem of prescribing the nodal set of the first nontrivial eigenfunction of the Laplacian in a conformal class. Our main result is that, given a separating closed hypersurface $\Sigma$ in a compact Riemannian manifold $(M,g_0)$ of ...
