Towards Unbiased BFS Sampling

Breadth First Search (BFS) is a widely used approach for sampling large graphs. However, it has been empirically observed that BFS sampling is biased toward high-degree nodes, which may strongly affect the measurement results. In this paper, we quantify an ...

Preference is biased by crowded facial expressions

Nathan Quentin Faivre

Crowding occurs when nearby flankers impede the identification of a peripheral stimulus. Here, we studied whether crowded features containing inaccessible emotional information can nevertheless affect preference judgments. We relied on gaze-contingent crow ...

Glucocorticoids act on glutamatergic pathways to affect memory processes

Maria del Carmen Sandi Perez

Glucocorticoids can acutely affect memory processes, with both facilitating and impairing effects having been described. Recent work has revealed that glucocorticoids may affect learning and memory processes by interacting with glutamatergic mechanisms. In ...

Models of 802.11 Multi-Hop Networks: Theoretical Insights and Experimental Validation

Patrick Thiran, Olivier Dousse, Adel Aziz, Mathilde Durvy

Wireless Multi-Hop CSMA/CA Networks are challenging to analyze. On the one hand, their dynamics are complex and rather subtle effects may severely affect their performance. Yet, understanding these effects is critical to operate upper layer protocols, such ...

AdS/QCD: the relevance of the geometry

Andrea Wulzer, Michele Redi, Diego Becciolini

We investigate the relevance of the metric and of the geometry in five-dimensional models of hadrons. Generically, the metric does not affect strongly the results and even flat space agrees reasonably well with the data. Nevertheless, we observe a preferen ...

A 3-D Audio-Visual Corpus of Affective Communication

Communication between humans deeply relies on the capability of expressing and recognizing feelings. For this reason, research on human-machine interaction needs to focus on the recognition and simulation of emotional states, prerequisite of which is the c ...

On the evolution of sexual reproduction in hosts coevolving with multiple parasites

Marcel Salathé

Host-parasite coevolution has been studied extensively in the context of the evolution of sex. Although hosts typically coevolve with several parasites, most studies considered one-host/one-parasite interactions. Here, we study population-genetic models in ...
