A Multiple Imputation Approach to Distinguish Curative From Life‐Prolonging Effects in the Presence of Missing Covariates

Biometrical Journal, Volume 68, Issue 3, June 2026.
ABSTRACT Medical advances have increased cancer survival rates and the possibility of finding a cure. Hence, it is crucial to evaluate the impact of treatments both in terms of cure and prolongation of survival. To achieve this, we may use a Cox proportional hazards cure model.

Input Layer Regularization and Automated Regularization Hyperparameter Tuning for Myelin Water Estimation Using Deep Learning

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
We propose a novel deep learning algorithm for predicting the myelin water fraction from multiple gradient‐echo or spin‐echo pulse sequences arising in magnetic resonance relaxometry (MRR) measurements of the human brain. Our method incorporates both regularized nonlinear least squares and pure deep learning through a concatenation paradigm known as ...

A nonstandard difference-integral method for the viscous Burgers’ equation [PDF]

, 2008
We develop a nonstandard difference-integral method based on a nonstandard finite difference method coupled with a CE–SE scheme. We use the viscous Burgers’ equation with preestablished conditions as a benchmark for testing our method.

Solving a fractional diffusion PDE using some standard and nonstandard finite difference methods with conformable and Caputo operators

Frontiers Appl. Math. Stat.
Fractional diffusion equations offer an effective means of describing transport phenomena exhibiting abnormal diffusion pat-terns, often eluding traditional diffusion models.We construct four finite difference methods where fractional derivatives are ...

AI‐Organized Multiscale Battery Modeling: Linking Structure and Property from Quantum to Device Scales

Small Structures, Volume 7, Issue 6, June 2026.
Multiscale modeling of battery systems combines quantum‐mechanical calculations, atomistic simulations, and mesoscale phase‐field approaches to describe processes spanning from reaction energetics to morphology evolution. Establishing consistent links between these scales remains a key challenge, particularly for the transfer of physical descriptors ...

An Accurate Predictor-Corrector-Type Nonstandard Finite Difference Scheme for an SEIR Epidemic Model

Journal of Mathematics, 2020
The present work deals with the construction, development, and analysis of a viable normalized predictor-corrector-type nonstandard finite difference scheme for the SEIR model concerning the transmission dynamics of measles. The proposed numerical scheme

But what about me? An exploration of who seeks and negotiates flexibility i‐deals

Journal of Occupational and Organizational Psychology, Volume 99, Issue 2, June 2026.
Abstract Our research undertakes two studies to address three questions: (1) who is likely to seek flexibility i‐deals; (2) who (among those who ask) is likely to have their request granted; and (3) what is the impact of a flexibility i‐deal on employee work–life balance and well‐being over time?
