Advanced Engineering Materials, EarlyView.Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Local density of states for different cancer cells in a one-dimensional photonic biosensor
Materials Research ExpressIn this work, we use dyadic Green’s functions to calculate local density of states in a finite-size one-dimensional photonic crystal surrounded by air.

Advanced Engineering Materials, EarlyView.A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

The cohomology of higher-dimensional shifts of finite type [PDF]
Pacific Journal of Mathematics, 1995 Combined review for the paper cited before and the present paper. The authors ask the question why `good' actions of the higher rank abelian groups \(\mathbb{Z}^d\) and \(\mathbb{R}^d\), for \(d\geq 2\) are much more rare and rigid than for similar actions on \(\mathbb{Z}\) and \(\mathbb{R}\). An example due to \textit{J. W. Kammeyer} [J. Anal.

Advanced Engineering Materials, EarlyView.Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Representation of right zero semigroups and their semilattices by a transformation semigroup
Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2022 Background. As is known, an arbitrary semigroup can be represented by a semigroup of transformations that are right shifts either in this semigroup itself or in the extended semigroup obtained from the original one by adding an outer unit. The problems

Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Involutions of Shifts of Finite Type: Fixed Point Shifts, Orbit Quotients, and the Dimension Representation [PDF]
, 2008 This thesis addresses several questions in symbolic dynamics. These involve the image of the dimension representation of a shift of finite type (SFT), the fixed point shifts of involutions of SFTs, and the conjugacy classes of orbit quotients of ...

Machine Learning Adversarial Attacks Using Partial Sinkhorn Optimization
IEEE Open Journal of Control SystemsAdversarial attacks are often modeled as pointwise perturbations of individual samples, which can miss structured distributional effects and may waste perturbation budget on examples that are already misclassified.
