Extension complexity of stable set polytopes of bipartite graphs
, 2017 The extension complexity xc(P) of a polytope P is the minimum number of facets of a polytope that affinely projects to P. Let G be a bipartite graph with n vertices, m edges, and no isolated vertices.

Restricted Tweedie stochastic block models
Canadian Journal of Statistics, Volume 54, Issue 2, June 2026.Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

Environmental and Protection Effects of Shark‐Companion Associations Across Three Ocean Basins
Ecology and Evolution, Volume 16, Issue 6, June 2026.Companion species frequently associate with large marine hosts, yet the ecological drivers of these relationships remain poorly understood. Using a global dataset of midwater BRUVS deployments, we modelled the presence and abundance of shark‐companion associations across seven shark species and three ocean basins.

Note. On (4; r, 6) bipartite biregular graphs.
, 2023 In this note, first we show that the incidence graph of a finite net is a bipartite biregular graph of girth 6, which in some cases is of minimal size (cf e.g.[1] when the net is obtained from an affine plane) and then we determine the order of (4; r ;

Energy‐Based Phase‐Locking State Analysis in Brain State Identification
Human Brain Mapping, Volume 47, Issue 8, June 1, 2026.EPLSA constructs an energy landscape from BOLD phase synchrony, achieving superior brain state classification and providing novel stability metrics. It demonstrates strong clinical translatability in characterizing sleep–wake transitions and Alzheimer's disease.

MedComm, Volume 7, Issue 6, June 2026.Preeclampsia, a severe pregnancy‐induced disorder unique to humans, affects ∼5% of pregnancies globally. To understand the pathogenesis of preeclampsia, this study performed a comprehensive multi‐omics analysis of early pregnancy placental biopsies (chorionic villus samples) from pregnancies that later developed preterm/term preeclampsia, compared to ...

Normal components, Kekule patterns, and Clar patterns in plane bipartite graphs
, 2002 As a general case of molecular graphs of polycyclic alternant hydrocarbons, we consider a plane bipartite graph G with a Kekule pattern (perfect matching).

Networks, Volume 87, Issue 4, Page 343-371, June 2026.ABSTRACT The analysis of certain properties of the underlying graph of a public transport network generates insights about the network's structure. Hereby, the choice of the graph representation depends on a trade‐off between complexity reduction and information preservation to adequately model a public transport network.

Stratified sampling enhances the understanding of bat–fruit networks in the southern Atlantic Forest
Oikos, Volume 2026, Issue 6, June 2026.Few studies have sought to understand the vertical patterns of bat–fruit systems, and therefore, it is not possible to evaluate whether interpretations based on data collected from a single stratum adequately represent the interaction patterns of this system. In this context, we evaluated the dissimilarity in the assemblage of frugivorous bats, plants,
