Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.

An etude on recursion relations and triangulations

open access: yesJournal of High Energy Physics, 2019
Following [1], we derive a recursion relation by applying a one-parameter deformation of kinematic variables for tree-level scattering amplitudes in bi-adjoint ϕ 3 theory.

Magnetic particle capture in high‐gradient magnetic separation: A theoretical and experimental study

open access: yesAIChE Journal, EarlyView.
Abstract High‐gradient magnetic separation (HGMS) has traditionally been used in mineral processing, with many effective models developed for typically employed rod‐wire shaped matrices. However, its potential in bioprocessing, especially for high‐value products, introduces new demands on plant and matrix design. This study presents a multi‐scale model

Notes on biadjoint amplitudes, Trop G(3, 7) and X(3, 7) scattering equations

open access: yesJournal of High Energy Physics, 2020
In these notes we use the recently found relation between facets of tropical Grassmannians and generalizations of Feynman diagrams to compute all “biadjoint amplitudes” for n = 7 and k = 3.

Reprogrammable, In‐Materia Matrix‐Vector Multiplication with Floppy Modes

open access: yesAdvanced Intelligent Systems, EarlyView.
This article describes a metamaterial that mechanically computes matrix‐vector multiplications, one of the fundamental operations in artificial intelligence models. The matrix multiplication is encoded in floppy modes, near‐zero force deformations of soft matter systems.

Adjoint orbits, generalised parallelisable spaces and consistent truncations

open access: yesJournal of High Energy Physics, 2019
The aim of this note is to present some new explicit examples of O(d, d)generalised Leibniz parallelisable spaces arising as the normal bundles of adjoint orbits O $$ \mathcal{O} $$ of some semi-simple Lie group G.

Submanifolds and Quotient Manifolds in Noncommutative Geometry [PDF]

open access: yes, 1995
We define and study noncommutative generalizations of submanifolds and quotient manifolds, for the derivation-based differential calculus introduced by M.~Dubois-Violette and P.~Michor. We give examples to illustrate these definitions.

Scattering forms, worldsheet forms and amplitudes from subspaces

open access: yesJournal of High Energy Physics, 2018
We present a general construction of two types of differential forms, based on any (n−3)-dimensional subspace in the kinematic space of n massless particles.

Are Australian students' academic skills declining? Interrogating 25 years of national and international standardised assessment data

open access: yesAustralian Journal of Social Issues, EarlyView.
Abstract Standardised tests of academic basic skills are an established feature of contemporary Australian schooling. Assessment results are widely reported and directly influence educational policymaking. Furthermore, Australian national educational priorities are linked to educational system accountability via the results of standardised tests. Given
