A conjugate gradient algorithm and its application in large-scale optimization problems and image restoration

open access: yesJournal of Inequalities and Applications, 2019
To solve large-scale unconstrained optimization problems, a modified PRP conjugate gradient algorithm is proposed and is found to be interesting because it combines the steepest descent algorithm with the conjugate gradient method and successfully fully ...

IgG4‐to‐IgG Ratio and Orbital Involvement Predict Clinical Response to B Cell Depletion in IgG4‐Related Disease

open access: yesACR Open Rheumatology, Volume 8, Issue 10, October 2026.
Objective IgG4‐related disease (RD) demonstrates ethnic variations in phenotype, but data from diverse US populations are limited. We characterized ethnic differences in organ involvement and evaluated predictors of treatment response in a multiethnic cohort.

Factorization Machine‐Based Active Learning for Functional Materials Design with Optimal Initial Data

open access: yesAdvanced Intelligent Discovery, Volume 2, Issue 5, October 2026.
This work investigates the optimal initial data size for surrogate‐based active learning in functional material optimization. Using factorization machine (FM)‐based quadratic unconstrained binary optimization (QUBO) surrogates and averaged piecewise linear regression, we show that adequate initial data accelerates convergence, enhances efficiency, and ...

Random Carbon Tax Policy and Investment Into Emission Abatement Technologies

open access: yesMathematical Finance, Volume 36, Issue 4, Page 804-825, October 2026.
ABSTRACT We analyze the problem of a profit‐maximizing electricity producer, subject to carbon taxes, who decides on investments into CO2$\rm CO_2$ abatement technologies. We assume that the carbon tax policy is random and that the investment in the abatement technology is divisible, irreversible, and subject to transaction costs.
