Performance of Cooperative Eigenvalue Spectrum Sensing with a Realistic Receiver Model under Impulsive Noise

Journal of Sensor and Actuator Networks, 2013
In this paper we present a unified comparison of the performance of four detection techniques for centralized data-fusion cooperative spectrum sensing in cognitive radio networks under impulsive noise, namely, the eigenvalue-based generalized likelihood ...

Quantum Kernel Learning for Small Dataset Modeling in Semiconductor Fabrication: Application to Ohmic Contact

Advanced Science, EarlyView.
A quantum kernel‐aligned regressor (QKAR) is developed for modeling Ohmic contact formation in GaN HEMT fabrication. Leveraging experimental data and a Pauli‐Z feature map enhanced with a quantum kernel alignment (QKA) layer, the model achieves superior predictive performance over classical methods.

Topological Singularities and Edge‐State Coupling Enable Robust on‐Chip Slow Light

Advanced Science, EarlyView.
This work demonstrates the first experimental observation of a topological quantum‐interference‐like effect in a 1D on‐chip system, utilizing two topological mechanisms for robust slow light. Topological charges ensure immunity to parameter deviations, while edge states provide robustness against disturbances.

Some inequalities for the Fan product of M-tensors

Journal of Inequalities and Applications, 2018
In this paper, we investigate some inequalities for the Fan product of M-tensors. We propose exact characterizations of M-tensors and establish some inequalities on the minimum eigenvalue for the Fan product of two M-tensors.

Rapid and Ultra‐Sensitive SARS‐CoV‐2 Subgenomic RNA Detection Using Single‐Molecule With a Large Transistor‐SiMoT Bioelectronic Platform

Advanced Electronic Materials, EarlyView.
The single‐molecule with a large transistor‐SiMoT is proposed for the detection of the subgenomic RNA of SARS‐CoV‐2, achieving a diagnostic sensitivity of 98.0% and a specificity of 87.8%. The SiMoT technology, currently at TRL‐5, is suitable for point‐of‐care settings and delivers the result to the end user in 30 min.

On the minimum number of eigenvalues of trees of diameter seven

The underlying graph $G$ of a symmetric matrix $M=(m_{ij})\in \mathbb{R}^{n\times n}$ is the graph with vertex set $\{v_1,\ldots,v_n\}$ such that a pair $\{v_i,v_j\}$ with $i\neq j$ is an edge if and only if $m_{ij}\neq 0$. Given a graph $G$, let $q(G)$ be the minimum number of distinct eigenvalues in a symmetric matrix whose underlying graph is $G$. A

Zwitterionic Heavier Pnictinidenes in Redox Catalysis

Angewandte Chemie, EarlyView.
Zwitterionic pnictinidenes: A new class of zwitterionic heavier pnictogen species stabilized by bis(N‐heterocyclic carbene)borate ligands is reported, enabling the isolation of Sb and Bi in multiple oxidation states. These thoroughly characterized systems exhibit cationic character and engage in redox catalysis, facilitating catalytic ...

Lignin Dissolution and Direct Ultrasmall‐Lignin‐Nanoparticle Formation in Acidic and Alkaline Deep Eutectic Solvents: A Molecular‐Level Insight

Angewandte Chemie, EarlyView.
Structural interpretation and molecular dynamics simulations reveal how molecular moieties and interaction networks influence the π–π stacking structures and conformational states of lignin during dissolution and aggregation: laterally shifted in deep eutectic solvents, offset‐stacked in tetrahydrofuran, and stretched in dimethyl sulfoxide.
