The asymptotic approach to the continuum of lattice QCD spectral observables

Physics Letters B, 2022
We consider spectral quantities in lattice QCD and determine the asymptotic behaviour of their discretization errors. Wilson fermion with O(a)-improvement, (Möbius) Domain wall fermion (DWF), and overlap Dirac operators are considered in combination with

Minimum power multicasting with delay bound constraints in Ad Hoc wireless networks [PDF]

, 2005
In this paper, we design a new heuristic for an important extension of the minimum power multicasting problem in ad hoc wireless networks. Assuming that each transmission takes a fixed amount of time, we impose constraints on the number of hops allowed ...

An O(kn)-Time Algorithm to Solve Steiner (k, k′)-Eccentricity on Trees

Axioms
Steiner (k,k′)-eccentricity on a given fixed k′-subset in a graph G is the maximum Steiner distance over all k-subsets of V(G) which contain the fixed k′-set, where the Steiner distance of a set is the size of a minimum Steiner tree on this set in a ...

Machine Learning Methods for the Prediction of the Inclusion Content of Clean Steel Fabricated by Electric Arc Furnace and Rolling

Metals, 2021
Machine Learning classification models have been trained and validated from a dataset (73 features and 13,616 instances) including experimental information of a clean cold forming steel fabricated by electric arc furnace and hot rolling. A classification

Predicting Foliar Nutrient Concentrations across Geologic Materials and Tree Genera in the Northeastern United States Using Spectral Reflectance and Partial Least Squares Regression Models

Journal of Remote Sensing
Spectral data can potentially offer a rapid assessment of nutrients in leaves and reveal information about the geologic history of the soil. This study evaluated the capability of the partial least squares regression (PLSR) for estimating foliar macro ...

Evolution of spectral behavior and chemical composition in the tree canopy of a dehesa ecosystem

Revista de Teledetección, 2016
In the context of the BIOSPEC and FLUXPEC projects (http://www.lineas.cchs.csic.es/fluxpec/), spectral and biophysical variables measurements at leaf level have been conducted in the tree canopy of a holm oak dehesa (Quercus ilex) ecosystem during four ...

Tree-level (pi, K)-amplitude and analyticity

, 1996
We consider the tree-level amplitude, describing all 3 channels of the binary (pi ,K)-reaction, as a meromorphic polynomially bounded function of 3 dependent complex variables.
