Across the edge: Spatial segregation drives community structure in tri-trophic multilayer networks at a forest-grassland edge. [PDF]
J Anim EcolThis study reveals how forest–grassland edges act as ecological barriers that shape tri‐trophic interaction networks. Using multilayer network theory, it uncovers how species influence and biodiversity patterns emerge across spatial layers, offering novel insights into edge‐driven community assembly and conservation in fire‐prone mosaics.

Data-efficient Neuroevolution with Kernel-Based Surrogate Models [PDF]
, 2018 Surrogate-assistance approaches have long been used in computationally expensive domains to improve the data-efficiency of optimization algorithms. Neuroevolution, however, has so far resisted the application of these techniques because it requires the ...

Spectral characterizations of complex unit gain graphs [PDF]
, 2022 While eigenvalues of graphs are well studied, spectral analysis of complex unit gain graphs is still in its infancy. This thesis considers gain graphs whose gain groups are gradually less and less restricted, with the ultimate goal of classifying gain ...

Gewichtung der visuellen Evidenz – Experimente zur Wahrnehmung von Datengrafiken [PDF]
, 2020 Data graphs are common in science and everyday life, providing a foundation for scientific conclusions and decision-making. Studies on the perception of graphs can improve the quality of these aspects. Two important tasks, visual estimation of model-data

The trace norm of r-partite graphs and matrices
, 2015 The trace norm $\left\Vert G\right\Vert _{\ast}$ of a graph $G$ is the sum of its singular values, i.e., the absolute values of its eigenvalues. The norm $\left\Vert G\right\Vert _{\ast}$ has been intensively studied under the name of graph energy, a ...

Beyond graph energy: norms of graphs and matrices
, 2016 In 1978 Gutman introduced the energy of a graph as the sum of the absolute values of graph eigenvalues, and ever since then graph energy has been intensively studied.

Smart Molecules, EarlyView.Conformational bifurcation in n‐alk‐1‐yne molecular junctions drives dual transport regimes, with unsupervised machine learning and XPS revealing distinct planar and skewed conformers influencing conductance and tunneling efficiency. This discovery highlights anchor‐group control as a key design principle for tailoring molecular electronic devices ...

American Journal of Political Science, EarlyView.Abstract How can defense alliances reap the efficiency gains of working together when coordination and opportunism costs are high? Although specializing as part of a collective comes with economic and functional benefits, states must bargain over the distribution of those gains and ensure the costs of collective action are minimized.
