Incremental Model Order Reduction of Smoothed‐Particle Hydrodynamic Simulations

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
The paper presents the development of an incremental singular value decomposition strategy for compressing time‐dependent particle simulation results, addressing gaps in the data matrices caused by temporally inactive particles. The approach reduces memory requirements by about 90%, increases the computational effort by about 10%, and preserves the ...

The density variance -- Mach number relation in supersonic, isothermal turbulence

open access: yes, 2010
We examine the relation between the density variance and the mean-square Mach number in supersonic, isothermal turbulence, assumed in several recent analytic models of the star formation process.

Cost‐effectiveness of a randomized controlled trial comparing low‐dose aspirin to placebo for the prevention of recurrent preterm birth

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 399-407, April 2025.
Abstract To assess the cost‐effectiveness of low‐dose aspirin compared to placebo for the prevention of recurrent preterm birth from a healthcare perspective. This was a cost‐effectiveness analysis alongside a multicenter, randomized, double‐blinded, placebo‐controlled trial.

AMR for low Mach number reacting flow [PDF]

open access: yes, 2006
We present a summary of recent progress on the development and application of adaptive mesh refinement algorithms for low Mach number reacting flows. Our approach uses a form of the low Mach number equations based on a general equation of state that discretely conserves both mass and energy.

Comparison of experimental and theoretical boundary-layer separation for inlets at incidence angle at low-speed conditions [PDF]

open access: yes
Comparisons between experimental and theoretical Mach number distributions and separation locations are presented for the internal surfaces of four different subsonic inlet geometries with exit diameters of 13.97 centimeters.

A Moving Frame Algorithm for High Mach Number Hydrodynamics

open access: yes, 2003
We present a new approach to Eulerian computational fluid dynamics that is designed to work at high Mach numbers encountered in astrophysical hydrodynamic simulations.

Probing polarization response of monolayer cell cultures with entangled photon pairs

open access: yesJournal of Biophotonics, EarlyView.
Innovative optical detection using polarization and quantum techniques is presented for biological sample analysis. This method utilizes non‐classical light, specifically entangled photon pairs, for enhanced sensitivity in low‐photon‐flux environments.
