Variational methods are becoming increasingly popular for inference and learning in probabilistic models. By providing bounds on quantities of interest, they offer a more controlled approximation framework than techniques such as Laplace’s method, while avoiding the mixing and convergence issues of Markov chain Monte Carlo methods, or the possible computational intractability of exact algorithm...

Micromechanical communication circuits fabricated via IC-compatible MEMS technologies and capable of low-loss filtering, mixing, switching, and frequency generation, are described with the intent to miniaturize wireless transceivers. Possible transceiver front-end architectures are then presented that use these micromechanical circuits in large quantities to substantially reduce power consumpti...

Micromechanical (or “μmechanical) communication circuits fabricated via IC-compatible MEMS technologies and capable of low-loss filtering, mixing, switching, and frequency generation, are described with the intent to miniaturize wireless transceivers. Possible MEMS-based receiver front-end architectures are then presented that use these micromechanical circuits in large quantities to enhance ro...

We re-derive the renormalization group equation for the effective coupling of the dimension five operator which corresponds to a Majorana mass matrix for the Standard Model neutrinos. We find a result which differs somewhat from earlier calculations, leading to modifications in the evolution of leptonic mixing angles and CP phases. We also present a general method for calculating β-functions fr...

• it stores and releases large quantities of heat, freshwater and soluble gases, • heat, freshwater and gas releases are sometimes substantially separated in space and time from their point of storage, due to ocean dynamics and mixing • freshwater and gas fluxes are determined partly by direct and indirect effects of ocean surface temperatures • carbon fluxes, storage and natural sequestration ...

After a brief discussion of the promise and limitations of the lattice technique, I review lattice QCD results for several quantities of phenomenological interest. These are: matrix elements for heavy-to-light meson decays, leptonic decay constants f B and f D , the parameters B B and B K for neutral B and K meson mixing respectively, the strong coupling constant, light quark masses and the lig...

The basic reproduction number R(0) is one of the most important quantities in epidemiology. However, for epidemic models with explicit social structure involving small mixing units such as households, its definition is not straightforward and a wealth of other threshold parameters has appeared in the literature. In this paper, we use branching processes to define R(0), we apply this definition ...

We show that a simple mixing idea allows to establish a number of explicit formulas for ruin probabilities and related quantities in collective risk models with dependence among claim sizes and among claim inter-occurrence times. Examples include compound Poisson risk models with completely monotone marginal claim size distributions that are dependent according to Archimedean survival copulas a...
