Whose Tweets are Surveilled for the Police: An Audit of Social-Media Monitoring Tool via Log Files [PDF]

, 2020
Social media monitoring by law enforcement is becoming commonplace, but little is known about what software packages for it do. Through public records requests, we obtained log files from the Corvallis (Oregon) Police Department's use of social media monitoring software called DigitalStakeout. These log files include the results of proprietary searches

ACSEE: Antagonistic Crowd Simulation Model with Emotional Contagion and Evolutionary Game Theory [PDF]

IEEE Transactions on Affective Computing (2019), 2019
Antagonistic crowd behaviors are often observed in cases of serious conflict. Antagonistic emotions, which is the typical psychological state of agents in different roles (i.e. cops, activists, and civilians) in crowd violent scenes, and the way they spread through contagion in a crowd are important causes of crowd antagonistic behaviors.

Percolation on interacting, antagonistic networks [PDF]

J. Stat. Mech. (2013) P05005, 2012
Recently, new results on percolation of interdependent networks have shown that the percolation transition can be first order. In this paper we show that, when considering antagonistic interactions between interacting networks, the percolation process might present a bistability of the equilibrium solution.

Towards Toxic and Narcotic Medication Detection with Rotated Object Detector [PDF]

arXiv, 2021
Recent years have witnessed the advancement of deep learning vision technologies and applications in the medical industry. Intelligent devices for special medication management are in great need of, which requires more precise detection algorithms to identify the specifications and locations.

Percolation on interdependent networks with a fraction of antagonistic interactions [PDF]

Journal of Statistical Physics, 152,1069 (2013), 2013
Recently, the percolation transition has been characterized on interacting networks both in presence of interdependent and antagonistic interactions. Here we characterize the phase diagram of the percolation transition in two Poisson interdependent networks with a percentage q of antagonistic nodes. We show that this system can present a bistability of

The Evolution of Substance Use Coverage in the Philadelphia Inquirer [PDF]

arXiv, 2023
The media's representation of illicit substance use can lead to harmful stereotypes and stigmatization for individuals struggling with addiction, ultimately influencing public perception, policy, and public health outcomes. To explore how the discourse and coverage of illicit drug use changed over time, this study analyzes 157,476 articles published in

Random Antagonistic Matrices [PDF]

J. Phys. A: Math. Theor. 49 (2016) 375601 (16pp), 2016
The ensemble of antagonistic matrices is introduced and studied. In antagonistic matrices the entries $\mathcal A_{i,j}$ and $\mathcal A_{j,i}$ are real and have opposite signs, or are both zero, and the diagonal is zero. This generalization of antisymmetric matrices is suggested by the linearized dynamics of competitive species in ecology.

Sex-specific recombination rates and allele frequencies affect the invasion of sexually antagonistic variation on autosomes [PDF]

Journal of Evolutionary Biology 26 (2013) 2428, 2013
The introduction and persistence of novel sexually antagonistic alleles can depend upon factors that differ between males and females. Understanding the conditions for invasion in a two-locus model can elucidate these processes. For instance, selection can act differently upon the sexes, or sex-linkage can facilitate the invasion of genetic variation ...

Emotional Contagion-Aware Deep Reinforcement Learning for Antagonistic Crowd Simulation [PDF]

arXiv, 2021
The antagonistic behavior in the crowd usually exacerbates the seriousness of the situation in sudden riots, where the antagonistic emotional contagion and behavioral decision making play very important roles. However, the complex mechanism of antagonistic emotion influencing decision making, especially in the environment of sudden confrontation, has ...

Extreme antagonism arising from gene-environment interactions [PDF]

, 2020
Antagonistic interactions in biological systems, which occur when one perturbation blunts the effect of another, are typically interpreted as evidence that the two perturbations impact the same cellular pathway or function. Yet, this interpretation ignores extreme antagonistic interactions wherein an otherwise deleterious perturbation compensates for ...
