Generalised species of rigid resource terms

Takeshi Tsukada, Kazuyuki Asada, C.-H. Luke Ong
2017 2017 32nd Annual ACM/IEEE Symposium on Logic in Computer Science (LICS)  
This paper introduces a variant of the resource calculus, the rigid resource calculus, in which a permutation of elements in a bag is distinct from but isomorphic to the original bag.  ...  It is designed so that the Taylor expansion within it coincides with the interpretation by generalised species of Fiore et al., which generalises both Joyal's combinatorial species and Girard's normal  ...  This is a generalised species by the action of isomorphisms to rigid resource terms defined in Section IV.  ...

Quantitative semantics of the lambda calculus: Some generalisations of the relational model

C.-H. Luke Ong
2017 2017 32nd Annual ACM/IEEE Symposium on Logic in Computer Science (LICS)  
We then consider two recent generalisations of the relational model: first, R-weighted relational models where R is a complete commutative semiring, as studied by Laird et al.; secondly, generalised species  ...  We present an overview of some recent work on the quantitative semantics of the λ-calculus. Our starting point is the fundamental degenerate model of linear logic, the relational model.  ...  Acknowledgements Much of this work was done in collaboration with Takeshi Tsukada, and also with Kazuyuki Asada.  ...

Robustness of rigid and adaptive networks to species loss

Savannah Nuwagaba, Feng Zhang, Cang Hui, Irene Sendiña-Nadal
2017 PLoS ONE  
We also show that adaptive behaviour renders networks vulnerable to species loss at initial stages but enhances long term stability of the system.  ...  However, whether adaptive networks are more robust to species loss than rigid ones depends on the structure of the network.  ...  Krasnov for providing interaction matrices of 27 real host-parasite networks and two anonymous reviewers for their valuable comments.

Non-breeding habitat preference affects ecological speciation in migratory waders

Ken Kraaijeveld
2007 Die Naturwissenschaften  
In this study, I test this hypothesis in waders of the sub-order Charadrii using the number of morphological sub-species per species as an index of diversity.  ...  Models of ecological speciation predict that certain types of habitat should be more conducive to species diversification than others.  ...  Acknowledgements I thank Martine Maan, David Roshier and Danny Rogers for their constructive comments on earlier versions of this paper.

Use of Game-Theoretical Methods in Biochemistry and Biophysics

Stefan Schuster, Jan-Ulrich Kreft, Anja Schroeter, Thomas Pfeiffer
2008 Journal of biological physics (Print)  
Thus, the outcome of the strategy adopted by one species (e.g., as a result of mutation and selection) depends on the strategy adopted by the other species.  ...  For example, some yeast species use metabolic pathways that waste nutrients, and in a dense tree canopy, trees grow taller than would be optimal for biomass productivity.  ...  The generalisation of the PD to more than two players has been termed "Tragedy of the Commons" [23] (see also [24] ).  ...

Effects of Turtle Excluder Devices on bycatch and discard reduction in the demersal fisheries of Mediterranean Sea

Among the four TEDs tested, both the semi-rigid TED and the Supershooter performed in accordance with the design objectives: total discards were reduced but total commercial catches were not significantly  ...  Due to lack of entry of turtles it was not possible to evaluate the ability of the different TEDs to release turtles, but one large loggerhead turtle (C. caretta) was captured during the experimental tows  ...  We would also like to thank Louise Henson (British Institutes, Italy) for helpful revision of the manuscript.  ...
