Similar to the role of Markov decision processes in reinforcement learning, Markov games (also known as stochastic games) form the basis for the study of multi-agent reinforcement learning and sequenc...
Sarcopenia is defined as the loss of muscle mass and function with aging, which accelerates after the seventh decade of life and is a harbinger for the onset of disability and institutionalization (1)...
The oft-quoted proverb, “Too many cooks spoil the broth,” is apt wisdom for describing challenges facing policy makers, public resource managers, ag producers, industry, residents and other ...
Segmentation of time-varying systems and signals into models whose parameters are piecewise constant in time is an important and well studied problem. It is here formulated as a least-squares problem ...
The problem of maximizing a sum of sigmoidal functions over a convex constraint set arises in many application areas. This objective captures the idea of decreasing marginal returns to investment, and...
For metaplectic covers of these groups, the Whittaker models may or may not be unique. Gelbart and Piatetski-Shapiro considered the representations of the double cover of SL2 that have unique Whitta...
We consider the problem of fitting given data with a convex polynomial. A technique to solve this problem using sum of squares polynomials is presented. This technique is extended to enforce convexity...
We present a methodology for analyzing robust independent-of-delay and delay-dependent stability of equilibria of systems described by nonlinear Delay Differential Equations by algorithmically constru...
We present an analysis of four sum rules, each based on chiral symmetry and containing the difference ρV(s) − ρA(s) of isovector vector and axialvector spectral functions. Experimental data from...
There is a ``toy'' weak matrix element which can be expressed as an integral over the vector and axial vector spectral functions, $\rho_V (s) - \rho_A (s)$. I review our recent evaluation of these spe...
A general class of inverse-moment sum rules was previously derived by the authors in a chiral perturbation theory (ChPT) study at two-loop order of the isospin and hypercharge vector-current propagato...
A new calculation of the isospin and hypercharge axial-vector current propagators [ ΔA33μν(q2) and ΔA88μν(q2)] to two loops in SU(3)×SU(3) chiral perturbation theory is used to derive chiral spectral ...
We reconsider the DMO sum rule in light of our recent two-loop calculations of isospin and hypercharge vector and axialvector current propagators in chiral perturbation theory. A modified derivation v...
We derive a sum rule which establishes a linear relation between a particle's anomalous magnetic moment and a quantity connected to the photoabsorption cross section. This quantity cannot be measured ...
