The ice breaker effect

Pearce, Eiluned; Launay, Jacques; Dunbar, Robin I. M. (The Royal Society, 2015)

It has been proposed that singing evolved to facilitate social cohesion. However, it remains unclear whether bonding arises out of properties intrinsic to singing or whether any social engagement can have a similar effect. ...

Iconicity can ground the creation of vocal symbols

Perlman, Marcus; Dale, Rick; Lupyan, Gary (2015)

Studies of gestural communication systems find that they originate from spontaneously created iconic gestures. Yet, we know little about how people create vocal communication systems, and many have suggested that vocalizations ...

Identifying diabetes-related important protein targets with few interacting partners with the PageRank algorithm

Grolmusz, Vince I. (2015)

Diabetes is a growing concern for the developed nations worldwide. New genomic, metagenomic and gene-technologic approaches may yield considerable results in the next several years in its early diagnosis, or in advances ...

Image analysis of weaverbird nests reveals signature weave textures

Bailey, Ida E.; Backes, André; Walsh, Patrick T. (The Royal Society, 2015)

In nature, many animals build structures that can be readily measured at the scale of their gross morphology (e.g. length, volume and weight). Capturing individuality as can be done with the structures designed and built ...

Image Processing Techniques for Unsupervised Pattern Classification

Botte-Lecocq, C.; Hammouche, K.; Moussa, A. (INTECH Open Access Publisher, 2007)

All the clustering methods presented in this chapter tend to generalize bi-dimensional procedures initially developed for image processing purpose. Among them, thresholding, edge detection, probabilistic relaxation, ...

Impact behaviour of freeze-dried and fresh pomelo peel

Thielen, Marc; Speck, Thomas; Seidel, Robin (2015)

Pomelos (Citrus maxima) are known for their thick peel which—inter alia—serves as energy dissipator when fruits impact on the ground after being shed. It protects the fruit from splitting open and thus enables the contained ...

Implementing and testing Bayesian and maximum-likelihood supertree methods in phylogenetics

Akanni, Wasiu A.; Wilkinson, Mark; Creevey, Christopher J (2015)

Since their advent, supertrees have been increasingly used in large-scale evolutionary studies requiring a phylogenetic framework and substantial efforts have been devoted to developing a wide variety of supertree methods ...

The importance of delineating networks by activity type in bottlenose dolphins (Tursiops truncatus) in CedarKey, Florida

Gazda, Stefanie; Iyer, Swami; Killingback, Timothy (The Royal Society, 2015)

Network analysis has proved to be a valuable tool for studying the behavioural patterns of complex social animals. Often such studies either do not distinguish between different behavioural states of the organisms or simply ...

Improved community detection inweighted bipartite networks

Beckett, Stephen J. (2016)

Real world complex networks are composed of non random quantitative interactions. Identifying communities of nodes that tend to interact more with each other than the network as a whole is a key research focus across ...

In the mood the dynamics of collective sentiments on Twitter

Charlton, Nathaniel (2016)

We study the relationship between the sentiment levels of Twitter users and the evolving network structure that the users created by @-mentioning each other. We use a large dataset of tweets to which we apply three sentiment ...

Increased natural mortality at low abundance can generate an Allee effect in amarine fish

Kuparinen, Anna; Hutchings, Jeffrey A. (2014)

Negative density dependent regulation of population dynamics promotes population growth at low abundance and is therefore vital for recovery following depletion. Inversely, any process that reduces the compensatory ...

Incubator-independent cell-culture perfusion platform for continuous long-termmicroelectrode array electrophysiology and time-lapse imaging

Saalfrank, Dirk; Konduri, Anil Krishna; Latifi, Shahrzad (2015)

Mostin vitro electrophysiology studies extract information and draw conclusions from representative, temporally limited snapshot experiments. This approach bears the risk of missing decisive moments that may make a difference ...

An individual based forest model links canopy dynamics and shade tolerances along a soil moisture gradient Jean Liénard and Nikolay Strigul

Liénard, Jean; Strigul, Nikolay (2016)

Understanding how forested ecosystems respond to climatic changes is a challenging problem as forest self-organization occurs simultaneously across multiple scales. Here, we explore the hypothesis that soil water availability ...
