Two-tensor, bimetric (or ‘‘f-g’’) gravity (BMG) was born as the fusion of the strong-interaction resonances of the 1960s (specifically that of a massive spin 2 field) with general relativity’s (GR) massless metric [1]. The idea was to join the two symmetrically by giving each its own Einstein-Hilbert action, then coupling the two resulting ‘‘spaces’’ through a nonderivative ‘‘mass term’’ that n...

One of the key characteristics of the contemporary network is its scale. The cloud data center network, which is considered as a key component of the current Internet, is normally composed of tens of thousands of devices. Besides, networks which connect data centers and their users are getting larger and becoming more complex because of the growing bandwidth requirement and user demands. This p...

Sperm competition is thought to be a major force driving the evolution of sperm shape and function. However, previous studies investigating the relationship between the risk of sperm competition and sperm morphometry revealed inconclusive results and marked differences between taxonomic groups. In a comparative study of two families of passerines (Fringillidae and Sylviidae) and also across spe...

Much work has gone into the construction of quasicontinuum energies that reduce the coupling error along the interface between atomistic and continuum regions. The largest consistency errors are typically pointwise O( 1 ε ) errors, and in some cases this has been reduced to pointwise O(1) errors. In this paper we show that one cannot create a coupling method using a finite-range coupling interf...
