Mitigating the Curse of Dimensionality: Sparse Grid Characteristics Method for Optimal Feedback Control and HJB Equations [PDF]

, 2016
We address finding the semi-global solutions to optimal feedback control and the Hamilton--Jacobi--Bellman (HJB) equation. Using the solution of an HJB equation, a feedback optimal control law can be implemented in real-time with minimum computational ...

Virtual element methods for HJB equations with Cordes coefficients

Computer Methods in Applied Mechanics and Engineering
In this paper, we propose and analyze both conforming and nonconforming virtual element methods (VEMs) for the fully nonlinear second-order elliptic Hamilton-Jacobi-Bellman (HJB) equations with Cordes coefficients. By incorporating stabilization terms, we establish the well-posedness of the proposed methods, thus avoiding the need to construct a ...

Breastmilk and medium‐chain triglyceride supplementation: Retrospective study on outcomes in biliary atresia infants after Kasai

Journal of Pediatric Gastroenterology and Nutrition, Volume 82, Issue 5, Page 1269-1277, May 2026.
Does breastmilk with medium‐chain triglycerides (MCT) after Kasai support growth and improve surgical outcomes? Abstract Objective To relate post‐surgical feeding regimens to growth and surgical outcomes in children with biliary atresia (BA) after hepato‐portoenterostomy (Kasai).

Nationwide pediatric prehospital blood product use after motor vehicle crashes 2020–2023

Transfusion, Volume 66, Issue S1, Page S124-S129, May 2026.
Abstract Background Previous studies suggest that in children with hemorrhagic shock following injury, prehospital blood transfusion improves survival. Quantifying and understanding the current demand for blood transfusion will help us improve the use and availability of prehospital blood for pediatric patients.

Stochastic Optimal Control with Delay in the Control: solution through partial smoothing

, 2015
Stochastic optimal control problems governed by delay equations with delay in the control are usually more difficult to study than the the ones when the delay appears only in the state.

Speciation, Structural Refinement, and Distribution of Ti Sites in Titanium Silicalite‐1 From 47/49Ti NMR Crystallography at 28.2 Tesla

Angewandte Chemie, Volume 138, Issue 15, 6 April 2026.
Titanium silicalite‐1 (TS‐1), used in industrial selective oxidation processes, depends on specific, yet still unresolved Ti sites, dispersed within the framework of an MFI‐zeolite. Applying high field (28.2 T) 47/49Ti NMR and 17O NMR spectroscopy for an array of TS‐1 catalysts enables the development of an NMR crystallography protocol and the ...

HJB Equation for Maximization of Wealth Under Insider Trading

Mediterranean Journal of Mathematics
Abstract In this paper, we combine the techniques of enlargement of filtrations and stochastic control theory to establish an extension of the verification theorem, where the coefficients of the stochastic controlled equation are adapted to the underlying filtration and the controls are adapted to a bigger filtration

Robust Exponential Hedging in a Brownian Setting [PDF]

This paper studies the robust exponential hedging in a Brownian factor model, giving a solvable example using a PDE argument. The dual problem is reduced to a standard stochastic control problem, of which the HJB equation admits a classical solution ...
