Spin-fluctuation theory beyond Gaussian approximation [PDF]
, 2010 A characteristic feature of the Gaussian approximation in the functional-integral approach to the spin-fluctuation theory is the jump phase transition to the paramagnetic state.

Polytopes and $C^1$-convex bodies [PDF]
Discrete Mathematics & Theoretical Computer Science, 2014 The face numbers of simplicial polytopes that approximate $C^1$-convex bodies in the Hausdorff metric is studied. Several structural results about the skeleta of such polytopes are studied and used to derive a lower bound theorem for this class of ...

Multiple Initial Point Approach to Solving Power Flows for Monte Carlo Studies
Energies, 2022 Power flow solvers typically start from an initial point of power injection. This paper constructs a system of multiple initial points (SMIP) to enable selection of an appropriate initial point, with the objective to achieve a balanced improvement in the

Rule induction based on rough sets from information tables having continuous domains
CAAI Transactions on Intelligence Technology, 2019 Information tables having continuous domains are handled by neighborhood rough sets. Two approximations in complete information tables are extended to handle incomplete information.

Electronic structure and x-ray magnetic dichroism in random substitutional alloys of f-electron elements [PDF]
, 1995 The Koringa-Kohn-Rostoker —coherent-potential-approximation method combines multiple-scattering theory and the coherent-potential approximation to calculate the electronic structure of random substitutional alloys of transition metals.

Universal Function Approximation by Deep Neural Nets with Bounded Width and ReLU Activations
Mathematics, 2019 This article concerns the expressive power of depth in neural nets with ReLU activations and a bounded width. We are particularly interested in the following questions: What is the minimal width w min ( d ) so that ReLU nets of width w ...

Integrating out the Dirac sea in the Walecka model [PDF]
, 2010 We derive a purely fermionic no-sea effective theory, featuring positive-energy states only for the Walecka model. In contrast to the so-called mean-field theory approach with the no-sea approximation, where the Dirac sea is simply omitted from the ...

Several rough set models in quotient space
CAAI Transactions on Intelligence Technology, 2022 In order to deal with coarse‐grained and multi‐grained calculation problems, as well as granularity transformation problems in information system, quotient space theory is introduced in rough set theory.
