Compact-Corrected MUSCL: A Flexible, Low-Cost High-Accuracy Scheme for High-Speed Flow Simulation

Algorithms
High-order numerical methods are essential for achieving predictive fidelity in modern computational fluid dynamics, yet many existing schemes face significant trade-offs between accuracy, robustness, and computational efficiency.

A robust, mass conservative scheme for two-phase flow in porous media including Hölder continuous nonlinearities

, 2017
In this work, we present a mass conservative numerical scheme for two-phase flow in porous media. The model for flow consists of two fully coupled, nonlinear equations: a degenerate parabolic equation and an elliptic one.

Representation of Sickle Cell Disease Patients in Pediatric and Adult Care: What We Discovered Using Informatics for Integrating Biology and the Bedside (i2b2) Data

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Transitioning from pediatric to adult care is a high‐risk period for individuals with sickle cell disease (SCD). An initial observation at one academic medical center suggested a sex‐based disparity in clinic populations, prompting a national investigation.

A numerical scheme for BSDEs

The Annals of Applied Probability, 2004
The author considers the decoupled system of forward-backward stochastic differential equations \[ \begin{aligned} X_t&=x + \int_0^t b(s,X_s) \,ds + \int_0^t \sigma(s,X_s)\,dW_s,\\ Y_t&= \Phi(X)+\int_t^Tf(s,X_s,Y_s,Z_s)\,ds-\int_t^TZ_s\,dW_s, \end{aligned} \tag{1} \] where \(b,\,\sigma\) and \(f\) are deterministic functions and \(W\) is a standard ...

Some numerical enhancements in a data assimilation scheme

, 2013
In this work we show preliminary numerical improvements in OceanVar, a 3D-Variational Scheme for data assimilation. The original assimilation scheme computes the horizontal error covariances by using a recursive gaussian filter of the first order (1st-RF)

Simulations of Compressible, Diffusive, Reactive Flows with Detailed Chemistry Using a High-Order Hybrid WENO-CD Scheme [PDF]

, 2012
A hybrid weighted essentially non-oscillatory (WENO)/centered-difference (CD) numerical method, with low numerical dissipation, high-order shock-capturing, and structured adaptive mesh refinement (SAMR), has been developed for the direct numerical ...

Lorlatinib‐Containing Therapy for MYCN‐Amplified, ALK‐Mutated Neuroblastoma With Bulky Leptomeningeal Relapse: A Case Report

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Central nervous system (CNS) relapse of neuroblastoma carries a poor prognosis, and craniospinal irradiation (CSI) poses substantial long‐term toxicity in young children. We report a toddler with MYCN‐amplified neuroblastoma harboring somatic ALK R1275Q who developed extensive leptomeningeal relapse with paraplegia.

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.
