Black holes, first-order flow equations and geodesics on symmetric spaces
, 2009 For both extremal and non-extremal spherically symmetric black holes in theories with massless scalars and vectors coupled to gravity, we derive a general form of first-order gradient flow equations, equivalent to the equations of motion.

Design of Two-phase Slug Flow Microreactors Using Reduced Order Flow Model
Chemical Engineering TransactionsTwo-phase slug flow microreactors (SFMRs) are known to be capable of achieving more efficient mass and heat transfer than conventional reactors. However, no method for designing SFMRs has been established so far.

On higher order geometric and renormalisation group flows
, 2010 Renormalisation group flows of the bosonic nonlinear \sigma-model are governed, perturbatively, at different orders of \alpha', by the perturbatively evaluated \beta--functions. In regions where \frac{\alpha'}{R_c^2}

Non-flow correlations and elliptic flow fluctuations in gold-gold collisions at sqrt(s_NN)= 200 GeV
, 2010 This paper presents results on event-by-event elliptic flow fluctuations in Au+Au collisions at sqrt(s_NN)=200Gev, where the contribution from non-flow correlations has been subtracted.

Exchange Rate Fundamentals and Order Flow (July 2004) [PDF]
This paper addresses the striking ability of transaction flows to explain exchange rate movements. Specifically, we examine whether this arises because transaction flows convey incremental information about fundamentals.

Third-order analysis of pseudopotential lattice Boltzmann model for multiphase flow
, 2016 In this work, a third-order Chapman-Enskog analysis of the multiple-relaxation-time (MRT) pseudopotential lattice Boltzmann (LB) model for multiphase flow is performed for the first time.

, 2015 In the following we study the qualitative properties of solutions to the geodesic flow induced by a higher order two-component Camassa-Holm system. In particular, criteria to ensure the existence of temporally global solutions are presented.

Flow-based nonperturbative simulation of first-order phase transitions
Journal of High Energy PhysicsWe present a flow-based method for simulating and calculating nucleation rates of first-order phase transitions in scalar field theory on a lattice. Motivated by recent advancements in machine learning tools, particularly normalizing flows for lattice ...

A fractional-order approach for transient creeping flow of spheres
AIP Advances, 2019 We provide experimental observations of power-law temporal response for spheres in the transient regime of a Stokes flow under the effect of gravity. The analysis of the fundamental physical mechanism leading to this unexpected behavior is performed via ...
