Lagrangian Reduction, the Euler--Poincar\'{e} Equations, and Semidirect Products [PDF]

open access: yes, 1997
There is a well developed and useful theory of Hamiltonian reduction for semidirect products, which applies to examples such as the heavy top, compressible fluids and MHD, which are governed by Lie-Poisson type equations.

Parental involvement and engagement during COVID‐19 lockdowns: School staff and parents' reflections about children's learning at home

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Valuing parental engagement, as part of home–school collaboration, can benefit children's learning. This article focuses on parents and school‐based staff's (N = 120) experiences of children's learning occurring at home during the COVID‐19 lockdowns (2020–2021), both school‐mandated and other learning activities.

A Parameter-Based Ostrowski–Grüss Type Inequalities with Multiple Points for Derivatives Bounded by Functions on Time Scales

open access: yesMathematics, 2018
In this paper, we present some Ostrowski⁻Grüss-type inequalities on time scales for functions whose derivatives are bounded by functions for k points via a parameter. The 2D versions of these inequalities are also presented.

Gaussian Subordination for the Beurling-Selberg Extremal Problem [PDF]

open access: yes, 2011
We determine extremal entire functions for the problem of majorizing, minorizing, and approximating the Gaussian function $e^{-\pi\lambda x^2}$ by entire functions of exponential type.

New time scale generalizations of the Ostrowski-Grüss type inequality for k points

open access: yesJournal of Inequalities and Applications, 2017
Two Ostrowski-Grüss type inequalities for k points with a parameter λ ∈ [ 0 , 1 ] $\lambda\in[0, 1]$ are hereby presented. The first generalizes a recent result due to Nwaeze and Tameru, and the second extends the result of Liu et al. to k points.

Accurate numerical methods for two and three dimensional integral fractional Laplacian with applications

open access: yes, 2019
In this paper, we propose accurate and efficient finite difference methods to discretize the two- and three-dimensional fractional Laplacian $(-\Delta)^{\frac{\alpha}{2}}$ ($0 < \alpha < 2$) in hypersingular integral form.

The Case of the Missing Green Iguana Predators: Reviews of Ecological Literature Should Go Beyond Google Scholar

open access: yesThe Bulletin of the Ecological Society of America, EarlyView.
Abstract Knowing about species interactions is essential for ecological research, conservation efforts, resource management, and maintaining healthy ecosystems, but many of these, such as reports of predation, may not always be published in easily located resources—if they are published at all.

A Guide to Bayesian Optimization in Bioprocess Engineering

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Bayesian optimization has become widely popular across various experimental sciences due to its favorable attributes: it can handle noisy data, perform well with relatively small data sets, and provide adaptive suggestions for sequential experimentation.

Efficient long division via Montgomery multiply [PDF]

open access: yes, 2016
We present a novel right-to-left long division algorithm based on the Montgomery modular multiply, consisting of separate highly efficient loops with simply carry structure for computing first the remainder (x mod q) and then the quotient floor(x/q ...
