A close look at the Centaurus A group of galaxies IV. Recent star formation histories of late-type dwarfs around CenA [PDF]
, 2012 We study a sample of 5 dwarf irregular galaxies in the CenA/M83 group, which are companions to the giant elliptical CenA. We aim at deriving their physical properties over their lifetime and compare them to those of dwarfs located in different ...

Fear, concealment, and time of day interactively predict group size of a common ungulate
Ecosphere, 2023 Animals commonly form groups with conspecifics. Hypotheses on the drivers of group size often (but not always) pertain to fear of predation and food availability or quality.

Feedback Loops in Opinion Dynamics of Agent-Based Models with Multiplicative Noise
Entropy, 2022 We introduce an agent-based model for co-evolving opinions and social dynamics, under the influence of multiplicative noise. In this model, every agent is characterized by a position in a social space and a continuous opinion state variable.

Group-cluster merging and the formation of starburst galaxies [PDF]
, 1998 A significant fraction of clusters of galaxies are observed to have substructure, which implies that merging between clusters and subclusters is a rather common physical process of cluster formation. It still remains unclear how cluster merging affects

Journal of Internet Services and Applications, 2014 Abstract Imagine a network of entities, being it replica servers aiming to minimize the probability of data loss, players of online team-based games and tournaments, or companies that look into co-branding opportunities. The objective of each entity in any of these scenarios is to find a few suitable partners to help them achieve a shared ...

Dwarf Spheroidal Satellite Formation in a Reionized Local Group [PDF]
, 2014 Dwarf spheroidal satellite galaxies have emerged a powerful probe of small-scale dark matter clustering and of cosmic reionization. They exhibit structural and chemical continuity with dwarf irregular galaxies in the field and with spheroidal galaxies in

A new dynamic approach for grouping learners using a genetic algorithm in social collaborative learning environments [PDF]
Computer Science Journal of MoldovaSocial media and social networking have spread widely in everyday life, so it is important to use them in collaborative learning. Forming appropriate learning groups is, therefore, an important objective. This paper presents a novel approach based on
