A Chemo‐Mechanically Fully Coupled Multiphase‐Field Model for Multicomponent Systems Accounting for Balance Equations on Singular Surfaces

open access: yesPAMM, Volume 26, Issue 1, March 2026.
ABSTRACT Chemo‐mechanically coupled phenomena such as stress‐driven diffusion and diffusion‐induced stresses are of high interest, for example, in battery materials and metals. In this work, a chemo‐mechanically fully coupled multiphase‐field model for a multicomponent system is derived and validated with a sharp interface solution. Ensuring mechanical

Solving a Random Asymmetric TSP Exactly in Quasi‐Polynomial Time W.H.P.

open access: yesRandom Structures &Algorithms, Volume 68, Issue 2, March 2026.
ABSTRACT Let the costs C(i,j)$$ C\left(i,j\right) $$ for an instance of the Asymmetric Traveling Salesperson Problem (ATSP) be independent copies of a nonnegative random variable C$$ C $$ from a class of distributions that include the uniform [0,1]$$ \left[0,1\right] $$ distribution and the exponential mean 1 distribution with mean 1.

Bootstrap Tests for Nonlinear Simplex Models

open access: yesStat, Volume 15, Issue 1, March 2026.
ABSTRACT We provide important contributions regarding hypothesis tests on the class of nonlinear simplex regression models. The performance of traditional asymptotic tests based on the maximum likelihood estimation (MLE) tends to exhibit considerable size distortions in finite samples.

On Wind Directions Estimated by Nacelle Lidar Under Different Reconstruction Methods

open access: yesWind Energy, Volume 29, Issue 3, March 2026.
ABSTRACT The wind direction is closely linked to the power performance and structural loads of wind turbines. Conventional nacelle‐mounted vanes or sonic anemometers face errors associated with airflow distortions caused by turbine blades. Nacelle‐mounted lidar systems offer line‐of‐sight speed measurements from multiple positions ahead of the rotor ...

A Mixture Transition Distribution Modeling for Higher‐Order Circular Markov Processes

open access: yesJournal of Time Series Analysis, Volume 47, Issue 2, Page 304-320, March 2026.
ABSTRACT This study considers the stationary higher‐order Markov process for circular data by employing the mixture transition distribution modeling. The underlying circular transition distribution is based on Wehrly and Johnson's bivariate joint circular models.

Cointegrating Polynomial Regressions With Power Law Trends

open access: yesJournal of Time Series Analysis, Volume 47, Issue 2, Page 331-344, March 2026.
ABSTRACT The common practice in cointegrating polynomial regressions (CPRs) often confines nonlinearities in the variable of interest to stochastic trends, thereby overlooking the possibility that they may be caused by deterministic components. As an extension, we propose univariate and multivariate CPRs that incorporate power law deterministic trends.

The ∞$\infty$‐categorical reflection theorem and applications

open access: yesJournal of Topology, Volume 19, Issue 1, March 2026.
Abstract We prove an ∞$\infty$‐categorical version of the reflection theorem of AdÁmek and Rosický [Arch. Math. 25 (1989), no. 1, 89–94]. Namely, that a full subcategory of a presentable ∞$\infty$‐category that is closed under limits and κ$\kappa$‐filtered colimits is a presentable ∞$\infty$‐category.

Entropy rigidity for cusped Hitchin representations

open access: yesJournal of Topology, Volume 19, Issue 1, March 2026.
Abstract We establish an entropy rigidity theorem for Hitchin representations of geometrically finite Fuchsian groups which generalizes a theorem of Potrie and Sambarino for Hitchin representations of closed surface groups. In the process, we introduce the class of (1,1,2)‐hypertransverse groups and show for such a group that the Hausdorff dimension of

Efficient Gradient‐Enhanced Bayesian Optimizer with Comparisons to Conjugate‐Gradient and Quasi‐Newton Optimizers for Unconstrained Local Optimization

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 4, 28 February 2026.
ABSTRACT The probabilistic surrogates used by Bayesian optimizers make them popular methods when function evaluations are noisy or expensive to evaluate. While Bayesian optimizers are traditionally used for global optimization, their benefits are also valuable for local optimization.
