Accelerating DSMC data extraction. [PDF]

, 2006
In many direct simulation Monte Carlo (DSMC) simulations, the majority of computation time is consumed after the flowfield reaches a steady state. This situation occurs when the desired output quantities are small compared to the background fluctuations. For example, gas flows in many microelectromechanical systems (MEMS) have mean speeds more than two

Boosting the convergence of DSMC by GSIS

Journal of Computational Physics
A deterministic-stochastic coupling scheme is developed for simulating rarefied gas flows, where the key process is the alternative solving of the macroscopic synthetic equations [Su et al., J. Comput. Phys., 407 (2020) 109245] and the mesoscopic equation via the asymptotic-preserving time-relaxed Monte Carlo scheme [Fei, J. Comput.

Comparison of discrete BGK-Shakhov system with DSMC [PDF]

AIP Conference Proceedings, 2012
Results obtained by numerically solving the discrete Boltzmann equation, using the Bhattnagar-Gross-Krook (BGK) relaxation approximation with Shakhov target distribution, are compared to those obtained by the Direct Simulation Monte-Carlo (DSMC) method. The relaxation dynamics of the BGK-Shakhov system are also compared to DSMC results.

Agar‐Based Optical Sensing System With a Phosphorescent Grid Pattern for Measuring Stress Distributions of Root Growth Using the Sampling Moiré Method

Advanced Materials Technologies, EarlyView.
This paper presents an agar medium with a phosphorescent grid pattern that measures the stress distribution generated by growing plant roots. Using phosphorescence, the system optically separates the grid pattern from the root and extracts the grid deformation.

Depth of Invasion Predicts Vocal Fold Motility and Muscle Invasion in Glottic Carcinoma

The Laryngoscope, EarlyView.
To determine whether depth of invasion (DOI) provides an objective surrogate for vocal fold motility and vocal muscle invasion in glottic squamous cell carcinoma. Methods and Results: In derivation and external validation cohorts, radiologic DOI strongly correlated with pathologic DOI and accurately predicted altered vocal fold motility and muscle ...

Sex Steroids Measurement by Mass Spectrometry in Hypogonadal Men in a Real‐World Setting: Serum Estradiol (E2) and E2 to Total Testosterone Ratio Do Not Differ Between Patients With Klinefelter Syndrome and Non‐Klinefelter Syndrome Hypogonadism

Andrology, EarlyView.
ABSTRACT Background Traditionally, Klinefelter syndrome (KS) was considered a clinical condition associated with hyperestrogenism. Aim To compare circulating sex steroids, particularly estrogens, in a cohort of KS and non‐KS hypogonadal men. Materials and Methods A cohort of hypogonadal men, treated and untreated, was prospectively enrolled in a real ...

A Two Degree of Freedom Approach for Discrete‐Time Sliding Mode Control

International Journal of Robust and Nonlinear Control, Volume 36, Issue 13, Page 6540-6551, 10 September 2026.
ABSTRACT This paper proposes a new two degree of freedom (2‐DOF) framework for discrete‐time sliding mode control (DSMC) that decouples the disturbed evolution from its nominal counterpart. The novel nominal/disturbed subsystem separation for DSMC can be used to define multiple closed‐loop specifications. The nominal regulation (or tracking) controller

Synergistic Engineering of Nanostructures via Anodic Aluminum Oxide Templates and Atomic Layer Deposition: Design Principles, Mechanisms, and Applications

Small Structures, Volume 7, Issue 8, August 2026.
Anodic aluminum oxide (AAO) templates combined with atomic layer deposition (ALD) constitute a synergistic platform for engineering functional nanostructures within highly ordered, high‐aspect‐ratio porous architectures. By linking precursor transport modeling, surface chemistry control, and tailored ALD strategies, this review establishes a unified ...
