Following the approach introduced by Cavers and Ho, the performance of component-interleaved multidimensional constellations over the Rayleigh fading channel is evaluated analytically. Error probabilities are approximated by the union bound using an exact expression of the pairwise error probability. Simulation results show that this bound can be used effectively as a design criterion for the s...

Investigation of non-pairwise protein structure score functions using sets of decoy structures

Given an edge weighted tree T and two non-negative real numbers dmin and dmax, a pairwise compatibility graph of T for dmin and dmax is a graph G = (V, E), where each vertex u ∈ V corresponds to a leaf u of T and there is an edge (u, v) ∈ E if and only if dmin ≤ dT (u, v) ≤ dmax in T . Here, dT (u, v) denotes the distance between u and v in T , which is the sum of the weights of the edges on th...

Most protein design algorithms search over discrete conformations and an energy function that is residue-pairwise, that is, a sum of terms that depend on the sequence and conformation of at most two residues. Although modeling of continuous flexibility and of non-residue-pairwise energies significantly increases the accuracy of protein design, previous methods to model these phenomena add a sig...

The paper proposes an intertemporal model of bargaining among heterogeneous buyers and sellers placed on an endogenous bipartite network. First, we characterize those networks whose trading restrictions are non-binding in that the induced outcome is “arbitrage-free,” i.e. all trade is conducted at the same price. Second, we assume that the network is endogenously determined, as captured by the ...
