There is intense debate in the industry about best practices for marking, managing and mitigating counterparty risk charges and funding costs. The inclusion of funding valuation adjustment(FVA) for ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Let Xt be a linear process defined by Xt=Σ k=0 ∞ψ kε t-k, where {ψ k,k≥ 0} is a sequence of real numbers and {ε k, k = 0,±1,±2,...} is a sequence of random variables. Two basic results, on the ...

In recent papers, McLeish and others have obtained invariance principles for weak convergence of martingales to Brownian motion. We generalize these results to prove that solutions of discrete-time ...

Symmetry and invariance lie at the heart of modern physical theories, serving as guiding principles in our understanding of the natural world. These ideas are central to elucidating conservation laws ...

Organizing principles are needed to link organismal, community and ecosystem attributes across spatial and temporal scales. Here we extend allometric theory—how attributes of organisms change with ...

IN THE span of 18 months, Isaac Newton invented calculus, constructed a theory of optics, explained how gravity works and discovered his laws of motion. As a result, 1665 and the early months of 1666 ...
