APPLICATION OF B-SPLINE METHOD IN SURFACE FITTING PROBLEM [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Fitting a smooth surface on irregular data is a problem in many applications of data analysis. Spline polynomials in different orders have been used for interpolation and approximation in one or two-dimensional space in many researches. These polynomials

Self-Similar Crossover in Statistical Physics

, 2000
An analytical method is advanced for constructing interpolation formulae for complicated problems of statistical mechanics, in which just a few terms of asymptotic expansions are available.

A new multiscale algorithm for solving the heat conduction equation

Alexandria Engineering Journal, 2023
In this paper, a multiscale algorithm has been initially proposed for a numerical solution to the heat conduction equation. Firstly, the differential form of the heat conduction equation is transformed into an integral form, and then the time variable is

Ergothioneine supplementation improves pup phenotype and survival in a murine model of spinal muscular atrophy

FEBS Letters, EarlyView.
Spinal muscular atrophy (SMA) is a genetic disease affecting motor neurons. Individuals with SMA experience mitochondrial dysfunction and oxidative stress. The aim of the study was to investigate the effect of an antioxidant and neuroprotective substance, ergothioneine (ERGO), on an SMNΔ7 mouse model of SMA.

Exponentiation of parametric Hamiltonians via unitary interpolation

Physical Review Research
The effort to generate matrix exponentials and associated differentials, required to determine the time evolution of quantum systems, frequently constrains the evaluation of problems in quantum control theory, variational circuit compilation, or Monte ...

Learning near‐optimal broadcasting intervals in decentralized multi‐agent systems using online least‐square policy iteration

IET Control Theory & Applications, 2021
Here, agents learn how often to exchange information with neighbours in cooperative multi‐agent systems (MASs) such that their linear quadratic regulator (LQR)‐like performance indices are minimized. The investigated LQR‐like cost functions capture trade‐

A Non-Equilibrium Interpolation Scheme for IB-LBM Optimized by Approximate Force

Axioms, 2023
A non-equilibrium scheme and an optimized approximate force are proposed for the immersed boundary–lattice Boltzmann method (IB-LBM) to solve the fluid–structure interaction (FSI) equations.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Towards a precision computation of f_Bs in quenched QCD

, 2003
We present a computation of the decay constant f_Bs in quenched QCD. Our strategy is to combine new precise data from the static approximation with an interpolation of the decay constant around the charm quark mass region.
