Limnology and Oceanography: Methods, EarlyView.Abstract Acoustic cameras, or imaging sonars, are often used to monitor marine energy sites in regions where the water is too dark or turbid for optical sensing. To do so more effectively, scientists are investigating automated detection methodologies to use on these data.

Networks, EarlyView.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.

Some Properties of Regular Line Graphs
مجلة علوم ذي قار, 2019 In this paper, the concept of regular line graph has been introduced. The maximum number of vertices with different degrees in the regular line graphs has also been studied.

Sidorenko's conjecture for blow-ups
Discrete Analysis, 2021 Sidorenko's conjecture for blow-ups, Discrete Analysis 2021:2, 13 pp. Let $G$ be a bipartite graph with finite vertex sets $X$ and $Y$. If $G$ has density $\alpha$, then the average degree of the vertices in $X$ is $\alpha|Y|$, so the mean-square degree

Stratified sampling enhances the understanding of bat–fruit networks in the southern Atlantic Forest
Oikos, EarlyView.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,

Using random walks to generate associations between objects.
PLoS ONE, 2014 Measuring similarities between objects based on their attributes has been an important problem in many disciplines. Object-attribute associations can be depicted as links on a bipartite graph.

Adaptive Bipartite Consensus of Second-Order Multi-Agent Systems With Bounded Disturbances
IEEE Access, 2020 This paper investigates distributed adaptive bipartite consensus for second-order multi-agent systems (MASs) with bounded disturbances under a signed graph. Based on adaptive variable structure control strategies, an adaptive bipartite consensus protocol

4-Factor-criticality of vertex-transitive graphs [PDF]
, 2014 A graph of order $n$ is $p$-factor-critical, where $p$ is an integer of the same parity as $n$, if the removal of any set of $p$ vertices results in a graph with a perfect matching.

People and Nature, EarlyView.Abstract Protected areas represent complex social‐ecological systems that require governance and management approaches that valorise and enhance positive relationships between people and nature. This study analyses the alignment between social and ecological systems to detect the social‐ecological fit of projects focused on biodiversity conservation ...
