Lateral fligh control design for a highly flexible aircraft using a nonsmooth method [PDF]

, 2009
This paper describes a nonsmooth optimization technique for designing a lateral flight control law for a highly flexible aircraft. Flexible modes and high-dimensional models pose a major challenge to modern control design tools.

A CECT‐Based 2PI System as a Novel Noninvasive Prognostic Tool for Hepatocellular Carcinoma: A Dual‐Validation Study

Cancer Science, EarlyView.
Using differential weighting, we developed a 2PI‐based risk stratification system for HCC recurrence. A comprehensive prognostic model incorporating clinical variables and the 2PI score further enhanced postoperative prediction in solitary HCC and showed initial generalizability across SR and RFA cohorts.

An Adaptive Multiple Shooting Strategy for Optimal Control

Optimal Control Applications and Methods, Volume 47, Issue 6, Page 1453-1471, November/December 2026.
We study how multiple shooting affects the convergence of Newton‐type methods for optimal control, comparing several shooting strategies across 40 benchmark problems. The study covers interior‐point and sequential quadratic programming methods with both Quasi‐Newton approximations and exact Hessians.

Mission‐Aligned Learning‐Informed Control of Autonomous Systems: Formulation and Foundations

Expert Systems, Volume 43, Issue 11, November 2026.
ABSTRACT Research, innovation and practical capital investment have been increasing rapidly toward the realization of autonomous physical agents. This includes industrial and service robots, unmanned aerial vehicles, embedded control devices, and a number of other realizations of cybernetic/mechatronic implementations of intelligent autonomous devices.

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

ACR 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.

Random Carbon Tax Policy and Investment Into Emission Abatement Technologies

Mathematical 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.

L∞$L^\infty$ compactness of solutions of quasilinear problems and applications

Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract For a (not necessarily smooth) bounded domain Ω$\Omega$ of RN$\mathbb {R}^N$, N⩾2$N \geqslant 2$ and a Carathéodory vector‐valued function a:Ω×RN→RN$a:\Omega \times \mathbb {R}^N \rightarrow \mathbb {R}^N$, we study the compactness of the inverse of the Leray–Lions operator A(u)=−div(a(x,∇u))$A(u)=-\text{div}(a(x, \nabla u))$, u∈W01,p(Ω)$u\in ...

The Dirichlet problem for discontinuous perturbations of the mean curvature operator in Minkowski space

Electronic Journal of Qualitative Theory of Differential Equations, 2015
Using the critical point theory for convex, lower semicontinuous perturbations of locally Lipschitz functionals, we prove the solvability of the discontinuous Dirichlet problem involving the operator $u\mapsto\mbox{div} \Big(\frac{\nabla u}{\sqrt{1 ...
