This paper investigates the role of ecological interactions in the evolution of complexity through the results of simulations. Webworld is a robust model of evolution in food webs. It is extended for variability of organism complexity under evolution. Statistical and network analysis indicates a clear tendency for complexification within the model, led by adaptations that initially disconnect s...

Software evolution requires an intelligent planning of evolution and maintenance activities in an organization. Intelligent planning means integrating the long-term strategy of a product’s evolution with short-term maintenance activities. This paper describes a successful example of software evolution in the context of the applied-research project APPLICATION2WEB. The paper describes experience...

Through a combination of deep wideeld imaging and near-IR spectroscopy, the NGST will be able to chart with unprecedented accuracy the evolution of cosmic structures after the `dark ages' (z < 5), when galaxies are thought to assemble and form the bulk of their stars. In particular, accurate measurements at all redshifts of the frequencies of Type II and Ia SNe could be used as a probe of the s...

 The Evolution of SDN and OpenFlow: A Standards Perspective Jean Tourrilhes; Puneet Sharma; Sujata Banerjee; Justin Pettit HP Laboratories HPL-2014-41 SDN; OpenFlow; Networking SDN is designed to address networking needs that are poorly addressed by existing networks, and therefore the OpenFlow protocol and its specification process are significantly different from most traditional network pro...

semilinear stochastic evolution equations with multiplicative l&apos;evy noise are considered‎. ‎the drift term is assumed to be monotone nonlinear and with linear growth‎. ‎unlike other similar works‎, ‎we do not impose coercivity conditions on coefficients‎. ‎we establish the continuous dependence of the mild solution with respect to initial conditions and also on coefficients. ‎as corollarie...

Aims. Our main goals are to get a deeper insight into the evolution and final fates of intermediate-mass, extremely metal-poor (EMP) stars. We also aim to investigate the C, N, and O yields of these stars. Methods. Using the Monash University Stellar Evolution code MONSTAR we computed and analysed the evolution of stars of metallicity Z = 10−5 and masses between 4 and 9 M , from their main sequ...

The availability of complete genome sequences for 12 Drosophila species provides an unprecedented resource for large-scale studies of genome evolution. In this study, we looked for correlated shifts in the patterns of genome and proteome evolution within the genus Drosophila. Specifically, we asked if the nucleotide composition of the Drosophila willistoni genome--which is significantly less GC...
