Inverse Extremal Eigenvalue Problems for Multi-Arrowhead Pentadiagonal Matrices
MathematicsWe address the inverse extremal eigenvalue problem (IEEP) for multi-arrowhead pentadiagonal matrices, a structured class that combines pentadiagonal bandwidth with an alternating arrowhead structure.

Advanced Materials, EarlyView.Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Extremal Values of Half-Eigenvalues for
Boundary Value Problems, 2010 For one-dimensional -Laplacian with weights in balls, we are interested in the extremal values of the th positive half-eigenvalues associated with Dirichlet, Neumann, and generalized periodic boundary conditions, respectively.

Extremal problems for logarithmic capacity and extremal length. [PDF]
, 1995 We solve extremal problems for two conformal invariants in the complex plane, logarithmic capacity and extremal length. For a finitely-connected domain $\Omega$ containing $\infty ,$ with boundary $\Gamma ,$ the logarithmic capacity $d(\Gamma )$ is ...

On the Extremal Aspect of the Frobenius Problem
Journal of Combinatorial Theory, Series A, 1996 Concerning the Frobenius number \(g= g(a_1, \dots, a_n)\) (cf. the review above) \textit{P. Erdös} and \textit{R. L. Graham} [Acta Arith. 21, 399-408 (1972; Zbl 0246.10010)] defined \(g(n, \ell)= \max_{a_n= \ell} g\), the maximum being taken over all sets of \(n\) coefficients with the maximal coefficient \(\ell\) \((\ell \geq n)\).

Advanced Materials, EarlyView.The perspective presents an integrated view of neuromorphic technologies, from device physics to real‐time applicability, while highlighting the necessity of full‐stack co‐optimization. By outlining practical hardware‐level strategies to exploit device behavior and mitigate non‐idealities, it shows pathways for building efficient, scalable, and ...
