Direct Simulation of Low-Pressure Supersonic Gas Expansions and its Experimental Verification

, 2008
The use of gas expansions to generate atomic or molecular beams has become a standard technique in nuclear and hadron physics for the production of polarized ion beams and gas targets.

Beyond direct simulation Monte Carlo (DSMC) modelling of collision environments [PDF]

, 2019
Direct simulation Monte Carlo (DSMC) models have been successfully adopted and adapted to describe gas flows in a wide range of environments since the method was first introduced by Bird in the 1960s.

“Steak Dry Aging”: An Innovative Approach to Producing High‐Yield, High‐Quality Dry‐Aged Beef

Journal of Food Science, Volume 91, Issue 4, April 2026.
ABSTRACT This study evaluated a novel steak dry‐aging (StDA) protocol in which portioned beef steaks were dry‐aged until reaching an average weight loss of 15% and subsequently wet‐aged to achieve a total aging time of either 14 or 28 days. The new protocol was compared with conventional dry aging (DA) for 28 days and unaged controls.

Stochastic Hard-Sphere Dynamics for Hydrodynamics of Non-Ideal Fluids [PDF]

, 2008
A novel stochastic fluid model is proposed with non-ideal structure factor consistent with compressibility, and adjustable transport coefficients. This Stochastic Hard Sphere Dynamics (SHSD) algorithm is a modification of the Direct Simulation Monte ...

Combined therapy with dutasteride and tadalafil vs dutasteride or tadalafil monotherapy in benign prostatic hyperplasia: a randomised phase III trial

BJU International, Volume 137, Issue 4, Page 698-707, April 2026.
Objectives To evaluate the efficacy and safety of a fixed‐dose combination (FDC) of dutasteride and tadalafil vs monotherapy in patients with benign prostatic hyperplasia (BPH). Patients and Methods This phase III trial enrolled 667 patients. After screening and washout, eligible patients were stratified by the baseline International Prostate Symptom ...

Simulating fluid flows in micro and nano devices : the challenge of non-equilibrium behaviour [PDF]

, 2009
We review some recent developments in the modelling of non-equilibrium (rarefied) gas flows at the micro- and nano-scale, concentrating on two different but promising approaches: extended hydrodynamic models, and lattice Boltzmann methods.

Chemistry Composition and Bioaccessibility Study of Phenolic Compounds and Carotenoids of New Brazilian Biofortified Sweet Potato “CIP BRS Nuti”

Food Chemistry International, Volume 2, Issue 1, Page 23-33, March 2026.
Phenolic compounds of sweet potato CIP BRS Nuti were evaluated for the first time. Catechin, epicatechin, and procyanidin B1 exhibited high bioaccessibility. ABSTRACT Sweet potatoes biofortified in carotenoids have been an alternative to combat malnutrition in vulnerable populations. This work is the first comprehensive study of the bioactive potential

Multiscale simulation of rarefied gas dynamics via direct intermittent GSIS-DSMC coupling

Advances in Aerodynamics
The general synthetic iterative scheme (GSIS) has proven its efficacy in modeling rarefied gas dynamics, where the steady-state solutions are obtained after dozens of iterations of the Boltzmann equation, with minimal numerical dissipation even using ...

Investigation of concentration variation of the components of a three-component gas mixtures in the radial and axial direction of a gas centrifuge machine under “total reflux flow” conditions by using the DSMC method [PDF]

مجله علوم و فنون هسته‌ای, 2019
In this paper, using a new combinatory meshing technique in the axisymmetric coordinate, a MCC-DSMC solver is introduced. Using this solver, the flow and the concentration variation inside a centrifuge machine in a rigid body rotation mode with the DSMC ...
