Comparing the power of phylogenetic, trait and network structure information to predict plant–frugivore interactions

open access: yesOikos, EarlyView.
Due to the constraints of limited effort and sampling error, observed species interaction networks are an imperfect representation of the ‘true' underlying community. Link prediction methods allow us to construct a potentially more complete representation of a given empirical network by guiding targeted sampling of predicted links, as well as offer ...

Output Feedback Design for Parameter Varying Systems Subject to Persistent Disturbances and Control Rate Constraints

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper develops a framework for designing output feedback controllers for constrained linear parameter‐varying systems that experience persistent disturbances. We specifically propose an incremental parameter‐varying output feedback control law to address control rate constraints, as well as state and control amplitude constraints.

On Distance-Based Topological Descriptors of Subdivision Vertex-Edge Join of Three Graphs

open access: yesIEEE Access, 2019
The analysis of networks and graphs through topological descriptors carries out a useful role to derive their underlying topologies. This process has been widely used in biomedicine, cheminformatics, and bioinformatics, where assessments based on graph ...

Moments in graphs [PDF]

open access: yes, 2012
Let $G$ be a connected graph with vertex set $V$ and a {\em weight function} $\rho$ that assigns a nonnegative number to each of its vertices. Then, the {\em $\rho$-moment} of $G$ at vertex $u$ is defined to be $M_G^{\rho}(u)=\sum_{v\in V} \rho(v)\dist ...

“Bad Things Happen in Philadelphia”: Managing Stigma and Threats in the Wake of False Criminal Accusations

open access: yesSymbolic Interaction, EarlyView.
In the aftermath of the 2020 U.S. election, the boundary between activism and extremism blurred, with election officials reporting violent threats and false accusations of election fraud. From a symbolic interactionist perspective, these attacks provide a unique lens for examining the consequences of being falsely labeled a criminal.

The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

STbayes: An R package for creating, fitting and understanding Bayesian models of social transmission

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract A critical consequence of joining social groups is the possibility of social transmission of information related to novel behaviours or resources. Network‐based diffusion analysis (NBDA) has emerged as a leading frequentist framework for inferring and quantifying social transmission, particularly in non‐human animal populations.

Harary and hyper-Wiener indices of some graph operations

open access: yesJournal of Inequalities and Applications
In this paper, we obtain the Harary index and the hyper-Wiener index of the H-generalized join of graphs and the generalized corona product of graphs. As a consequence, we deduce some of the results in (Das et al. in J. Inequal. Appl. 2013:339, 2013) and

Effects of Lombard Reflex on the Performance of Deep-Learning-Based Audio-Visual Speech Enhancement Systems

open access: yes, 2018
Humans tend to change their way of speaking when they are immersed in a noisy environment, a reflex known as Lombard effect. Current speech enhancement systems based on deep learning do not usually take into account this change in the speaking style ...

The public agglomeration effect: Urban–rural divisions in government efficiency and political preferences

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Why and when do cities vote for the left? The emergence of the urban–rural divide in the United States in the 1930s is inconsistent with canonical theories of cleavages. This paper introduces an explanation: agglomeration effects. The provision of government services is more efficient in urban environments because of nonrivalries, economies of
