Improved Multilevel Monte Carlo Convergence using the Milstein Scheme [PDF]

, 2008
In this paper we show that the Milstein scheme can be used to improve the convergence of the multilevel Monte Carlo method for scalar stochastic differential equations. Numerical results for Asian, lookback, barrier and digital options demonstrate that the computational cost to achieve a root-mean-square error of e is reduced to O(e -2).

Topics as Outcomes: Modeling the Influence of Intergovernmental Grants on Policy Diffusion

Policy Studies Journal, EarlyView.
ABSTRACT Intergovernmental grants stimulate the diffusion of policy reforms, as the federal government provides states with a financial incentive to adopt policies aligned with federal priorities. Less is known about the extent to which these grants also stimulate horizontal diffusion across states.

COVARIANCE ESTIMATION USING h-STATISTICS IN MONTE CARLO AND MULTILEVEL MONTE CARLO METHODS

International Journal for Uncertainty Quantification
We present novel Monte Carlo (MC) and multilevel Monte Carlo (MLMC) methods to determine the unbiased covariance of random variables using h-statistics. The advantage of this procedure lies in the unbiased construction of the estimator's mean square error in a closed form. This is in contrast to conventional MC and MLMC covariance estimators, which are

The Drivers of Science Referenced in US EPA Regulatory Impact Analyses: Open Access, Professional Popularity, and Agency Involvement

Regulation &Governance, EarlyView.
ABSTRACT We perform bibliometric analysis on documents for 255 Regulatory Impact Analyzes (RIAs) prepared by the US Environmental Protection Agency (EPA) from 1980 through 2024. Using a series of automated information extraction methods, we extract references from these documents and match them to bibliographic records.

Navigating the Path to Mathematics Success: Exploring Academic Performance and Exclusionary School Discipline Among Black Students

School Science and Mathematics, EarlyView.
ABSTRACT This study examines the predictive relationships among early mathematics and reading achievement, school discipline, and later mathematics performance for Black students. Using path analysis, we analyze a cohort of 36,668 Black students in Texas public schools from fourth to seventh grade.

Proprioceptive integration in motor control

The Journal of Physiology, EarlyView.
Abstract figure legend A virtual reality (VR)‐based reaching task reveals how proprioceptive feedback affects the perceived and actual movement speed of active movements, as well as the perceived hand position. When an antagonist vibration was applied, subjects tended to overestimate their movement speed while also decreasing their actual movement ...

Supporting the Synergy Between School Meal Programs and Food Banks to Combat Food Insecurity Among Children: A Bayesian Mindsponge Framework Analysis

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background and Aims Food banks play a major role in the food aid sector by distributing donated and purchased groceries directly to food‐insecure families, which helps reduce food insecurity. On the other hand, school meal programs are implemented in many countries to combat food insecurity among school‐aged children.

A Longitudinal Mediation Analysis of Quality of Life After Metabolic and Bariatric Surgery

Obesity Science &Practice, Volume 12, Issue 2, April 2026.
ABSTRACT Background and Aim Severe obesity is associated with physical comorbidity and impaired health‐related quality of life (HRQoL). Although metabolic and bariatric surgery (MBS) is generally associated with improvements in HRQoL and mental health, inter‐individual variability is substantial, and the functional mechanisms through which preoperative

Integration of Machine Learning With PBPK and QSAR Modeling Approaches to Facilitate Drug Discovery and Development

CPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 4, April 2026.
ABSTRACT This review examines the application of machine learning (ML) in physiologically based pharmacokinetic (PBPK) modeling through improved prediction of input parameters, particularly via quantitative structure–activity relationship (QSAR) models, for absorption, distribution, metabolism, and excretion (ADME) properties across drug development ...
