The social implications of winner and loser effects

L. A. Dugatkin, M. Druen
2004 Proceedings of the Royal Society of London. Biological Sciences  
We report the results of experimentally manipulated winner and loser effects on hierarchy formation in a socially living species, the green swordtail, Xiphophorus helleri.  ...  To our knowledge, experimental work, however, has focused exclusively on pairwise interactions, and not the extent to which winner and loser effects impact hierarchy formation.  ...  Table 1 . 1 The expected types of hierarchy if winner and loser effects had no impact on hierarchy formation versus the observed hierarchy formation.  ...

2008 Proceedings of the 2008 GECCO conference companion on Genetic and evolutionary computation - GECCO '08  
This paper analyses the default hierarchy formation theory presented by [14] as a way of favoring the hierarchical arrangement of rules, and also the organizational learning theory [17] for adjusting the  ...  We suggest a new method, combining both organizational learning and default hierarchy formation, for solving multi-label problems.  ...  DEFAULT HIERARCHY FORMATION Default Hierarchies are layered rule sets where default rules cover a broad part of the system responses, and exception rules are responsible for handling responses where the  ...

Machine learning and concept formation

Pat Langley
1987 Machine Learning  
Pat Langley University of California, Irvine Langley@CIP.UCI.EDU  ...  We believe these features characterize much of the process of human concept learning. Models of concept formation Exceptions to the above trends certainly exist.  ...  Thus, models of concept learning should address the formation of conceptual hierarchies as well as the formation of individual 4' categories.  ...

Structures of the neutrino mass spectrum and of lepton mixing as results of mirror-symmetry breaking

I. T. Dyatlov
2017 Physics of Atomic Nuclei  
The peculiarities of the Standard Model (SM): quark and lepton mass hierarchy and the neutrino spectrum different from this hierarchy appear to be necessary conditions for reproduction of such a structure  ...  The specific violated mirror symmetry model is capable of generating the observed lepton weak mixing matrix with a structure similar to the observed one that almost lacks any visible regularities (the  ...  It is obvious that (7) In both cases, all properties except the weak ones, R⟷L, must be identical.  ...

Encoding the Java Virtual Machine's Instruction Set

Michael Eichberg, Andreas Sewe
2011 Electronical Notes in Theoretical Computer Science  
The XML format hereby specifies both the format of the instructions and their effect on the stack and the local registers upon execution.  ...  To assess the usefulness of our approach, we have used the encoding of the Java Virtual Machine's instruction set to develop a framework for the analysis and transformation of Java class files.  ...  For example, exceptions < (exception @type)+ > specifies that the XML-element exceptions has one or more exception child elements that always have the attribute type.  ...

The First Description of Dominance Hierarchy in Captive Giraffe: Not Loose and Egalitarian, but Clear and Linear

Edita Horová, Karolína Brandlová, Markéta Gloneková, Elissa Z. Cameron
2015 PLoS ONE  
Based on the differences in resource-holding potential, we suggested that the rank of an individual would be affected by age and sex.  ...  Consequently, we suggest that agonistic encounters should be more frequent, leading to the establishment of the dominance hierarchy.  ...  We are grateful to collaborating staff of the zoos, namely, to Jaroslav Šimek, Jan Marek, Barbora Dobiášová, and Kateřina Pechrová from Prague Zoo, Luboš Melichar from Liberec Zoo, and Luděk Čulík from  ...

3D Scene Description and Recording Mechanism: A Comparative Study of Various 3D Create Tools

2020 Journal of system and management sciences  
The proposed technique is to classify 3D contents into asset, hierarchy, and script, and then reanalyze and mainly focused on the hierarchy and script transformation.  ...  As a result, content created in one 3D create tool is often not available in another 3D create tool.  ...  Among them, we focused on the conversion of hierarchy and scripts, except for assets and multimedia files that are independent of 3D create tools.  ...

Quantify entanglement by concurrence hierarchy

Heng Fan, Keiji Matsumoto, Hiroshi Imai
2003 Journal of Physics A: Mathematical and General  
We propose to use this concurrence hierarchy as measurement of entanglement. This measurement does not increase under local quantum operations and classical communication.  ...  The first one is the original concurrence defined by Wootters et al in 2-level quantum system and generalized to d-level pure quantum states case.  ...  Acknowlegements: One of the authors, H.F. would like to thank W.Y.Hwang, T.Shimono, X.B.Wang, and H.Yura for numerous useful discussions, and stimulating talks in ERATO internal seminars.  ...

Modelling Dominance Hierarchies Under Winner and Loser Effects

Klodeta Kura, Mark Broom, Anne Kandler
2015 Bulletin of Mathematical Biology  
In this paper we develop a model of dominance hierarchy formation based upon the concept of winner and loser effects using a simulation-based model, and consider the linearity of our hierarchy using existing  ...  We are particularly interested in the question of how many fights are necessary to establish a dominance hierarchy.  ...  Landau ( [31] , [32] ) considered the combined effects of winner and loser effects on hierarchy formation.  ...
