Design and Analysis of Compression–Torsion Coupling Metamaterials Using the Golden Section Method

Advanced Engineering Materials, EarlyView.
A novel compression–torsion metamaterial is engineered using inclined rods and symmetry breaking. To optimize its torsional performance, the golden section method is employed. The mechanical response of the metamaterial is validated through both numerical analysis and experimental validation.

Tailoring Li‐ion Storage and Transport in Two‐Dimensional Conjugated Metal‐Organic Frameworks via Precise Nitrogen Incorporation

Advanced Functional Materials, EarlyView.
Two nitrogen‐doped 2D conjugated metal‐organic frameworks (2D c‐MOFs, namely Cu‐Nx‐OHBA, x = 2 or 4) are synthesized, featuring precise nitrogen incorporation via rational ligand design. The Cu‐Nx‐OHBA 2D c‐MOFs are largely tailorable by varying skeletal nitrogen density, with respect to electrical conductivity, Li‐storage capacitance, and Li‐transport

Reduced Graphene Oxide Transparent Electrodes Enabling Compact Soft Tunable Lenses

Advanced Functional Materials, EarlyView.
By spray‐coating an elastomeric membrane with reduced graphene oxide (rGO) at various surface densities, elastomeric actuators are manufactured. Electro‐mechano‐optical characterizations show the suitability of rGO as an effective material for compliant, semi‐transparent electrodes, enabling soft electrically tunable lenses with a compact form factor ...

Bessel-type inequalities in semi-Hilbert spaces with applications to operator tuples

Journal of Inequalities and Applications
Consider a non-zero positive operator A on a complex Hilbert space ( H , 〈 ⋅ , ⋅ 〉 ) $(\mathfrak{H}, \langle \cdot , \cdot \rangle )$ . This operator induces an A-semi-inner product defined by ( u ∣ v ) A : = 〈 A u , v 〉 $(u \mid v)_{\mathbf{A ...

Extending Polynomially Normal Operators to (P, Q)-Normal Operators in Semi-Hilbertian Spaces

Mathematics
This paper is devoted to the introduction and systematic study of (P,Q)-normal operators in the context of semi-Hilbertian spaces, where P and Q are non-constant complex polynomials in one variable.

PIP-Space Valued Reproducing Pairs of Measurable Functions

Axioms, 2019
We analyze the notion of reproducing pairs of weakly measurable functions, a generalization of continuous frames. The aim is to represent elements of an abstract space Y as superpositions of weakly measurable functions belonging to a space Z : = Z ...

$\mathcal{A}$-Joint Numerical Radius Bounds for Operator Pairs in Semi-Hilbert Spaces with Applications

Mathematics
Consider a complex Hilbert space X,⟨·,·⟩ equipped with a positive (semidefinite) bounded linear operator A on X. The A-joint numerical radius for two A-bounded operators T and S is defined as ωA,e(T,S)=sup∥x∥A=1⟨Tx,x⟩A2+⟨Sx,x⟩A2.
