Dynamic Analysis of a Family of Iterative Methods with Fifth-Order Convergence

Fractal and Fractional
In this paper, a new class of fifth-order Chebyshev–Halley-type methods with a single parameter is proposed by using the polynomial interpolation method. The convergence order of the new method is proved.

A New Explicit Magnus Expansion for Nonlinear Stochastic Differential Equations

Mathematics, 2020
In this paper, based on the iterative technique, a new explicit Magnus expansion is proposed for the nonlinear stochastic equation d y = A ( t , y ) y d t + B ( t , y ) y ∘ d W . One of the most important features of the explicit Magnus method is

Stellar winds from Massive Stars [PDF]

, 2000
We review the various techniques through which wind properties of massive stars - O stars, AB supergiants, Luminous Blue Variables (LBVs), Wolf-Rayet (WR) stars and cool supergiants - are derived. The wind momentum-luminosity relation (e.g.

n-th Order Functional Problems with Resonance of Dimension One

Mathematics, 2021
We consider the nonlinear n-th order boundary value problem Lu=u(n)=f(t,u(t),u′(t),…,u(n−1)(t))=Nu given arbitrary bounded linear functional conditions Bi(u)=0, i=1,…,n and develop a method that allows us to study all such resonance problems of order one,

Holographic microscopy reconstruction in both object and image half spaces with undistorted 3D grid [PDF]

, 2015
We propose an holographic microscopy reconstruction method, which propagates the hologram, in the object half space, in the vicinity of the object. The calibration yields reconstructions with an undistorted reconstruction grid i.e.

Measurement of R(D) and R(D*) with a Semileptonic Tagging Method

Physical review letters, 2020
The experimental results on the ratios of branching fractions R(D)=B(¯B→Dτ−¯ντ)/B(¯B→Dℓ−¯νℓ) and R(D∗)=B(¯B→D∗τ−¯ντ)/B(¯B→D∗ℓ−¯νℓ), where ℓ denotes an electron or a muon, show a long-standing discrepancy with the standard model predictions, and might hint at a violation of lepton flavor universality. We report a new simultaneous measurement of R(D) and
