New Acceleration Schemes with the Asymptotic Expansion in Monte Carlo Simulation (Revised in June 2005, subsequently published in "Advances in Mathematical Economics", Vol.8, 411-431, 2006. ) [PDF]

In the present paper, we propose a new computational technique with the Asymptotic Expansion (AE) approach to achieve variance reduction of the Monte-Carlo integration appearing especially in finance.

Association Between Genetic Ancestry and Multiple Sclerosis Severity

Annals of Neurology, EarlyView.
Objective The objective of this study was to determine whether genetic ancestry is associated with differences in the clinical course of multiple sclerosis (MS). Methods Participants with MS living in the United Kingdom >18 years old were recruited from 2021 to 2025 and genotyped from saliva using a commercial array. Genetic ancestry was inferred using

Proposal of a Novel Physical Parameter Characterizing Solar Wind Speed in a Wave-driven Model

The Astrophysical Journal
Empirical solar wind speed models play an important role in enabling space weather forecasting with low computational cost. Among these, one model (called the Wang–Sheeley model) is based on the asymptotic expansion factor.

Serum Chitotriosidase Links to Activated Glia at Chronic Active Lesion Rims in Multiple Sclerosis Brain

Annals of Neurology, EarlyView.
Objective The objective of this study was to explore the association between 18 kDa translocator protein (TSPO)‐positron emission tomography (PET)–measurable glial activation and serum chitotriosidase (CHIT1) in people with multiple sclerosis (pwMS), and its expression in postmortem MS brain tissue.

Hybrid Inertial–Centrifugal Gas–Liquid Separator: CFD‐Driven Optimization Using Coupled Discrete Phase and Wall‐Film Modeling With Response Surface Methodology

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Efficient removal of liquid aerosols from compressed gas streams is essential in chemical and energy processes. Conventional separators relying on a single mechanism (inertial or centrifugal) struggle to capture both fine and coarse droplets simultaneously.

Residual Strength Prediction of Chemically Reactive Two‐Phase Nanofluid Flow in a Bingham–Papanastasiou Rheological Theory Using a Morlet‐Based Wavelet Neural Network Approach

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The behavior of nanofluid flow involving a zero‐mass flux condition has received considerable interest because of a realistic scenario. In reality, this condition confines the optimistic accumulation or disappearance of nanoparticles past a sheet, constructing a more physically realistic demonstration through several applications, such as heat

Streamline and Isotherm Visual Analysis of Darcy–Forchheimer von Karman Spinning Flow of Maxwell Fluid Over a Stretching Disk With Quadratic Temperature‐Dependent Heat Source

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This research paper provides an extensive study of the effects of Darcy–Forchheimer von‐Karman spinning flow of Maxwell fluid across a stretching disk including the effect of heat generation based on a nonlinear function of temperature. The flow system is influenced by thermal radiations and Arrhenius activation energy.

MHD Maxwell Hybrid Nanofluid Transport Featuring Solar Radiation and Thermo‐Diffusive Impacts Over a Permeable Slanted Stretching Sheet

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Hybrid nanofluids have emerged as next‐generation working fluids for advanced engineering application due to their superior heat transport capability in relation to the conventional nanofluids. Motivated by the rising demand for accurate prediction of transport phenomena under realistic operating situations, the present study examines the ...
