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

open access: yesJournal 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 ...

Symmetry Breaking in Chemical Systems: Engineering Complexity Through Self‐Organization and Marangoni Flows

open access: yesAdvanced Science, EarlyView.
We show that solutal Marangoni flows in thin films climbing the outer surfaces of hydrophilic obstacles break circular Belousov‐Zhabotinsky waves into striking flower‐like patterns. Evaporation‐driven surface‐tension gradients, coupled with gravity, trigger the instability; above a threshold, petal number scales linearly with obstacle diameter ...

Some inequalities for the Fan product of M-tensors

open access: yesJournal 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.

Scrambling‐Enhanced Quantum Battery Charging in Black Hole Analogues

open access: yesAdvanced Science, EarlyView.
By employing a black‐hole‐analog quantum battery constructed from a position‐dependent XY model, its dynamical behavior is investigated through a quench of the scrambling parameter. It is systematically quantified that how the simulated scrambling improves key performance metrics‐namely, stored energy, peak power, and charging time‐thereby offering a ...

MIM‐Diode‐Like Rectification in Lateral 1T/1H/1T‐MoS2 Homojunctions via Interfacial Dipole Engineering

open access: yesAdvanced Electronic Materials, EarlyView.
The metallic 1T and semiconducting 1H phases of MoS2 enable phase‐engineered 1T/1H/1T homojunctions that exhibit MIM‐diode‐like rectification without dissimilar electrodes. Asymmetric 1T/1H interfaces induce interface dipoles and a built‐in potential drop across the 1H barrier, creating a trapezoidal tunnel barrier at zero bias and yielding diode‐like ...

The Role of Coordination Mechanisms and Transaction Costs Promoting Sustainability Performance in Agri‐Food Supply Chains: Evidence From Ecuador

open access: yesAgribusiness, EarlyView.
ABSTRACT Social tensions and resource depletion pose significant challenges to the agri‐food sector, highlighting the need for coordinated strategies to ensure sustainability in supply chains. Despite its critical importance, the relationship between coordination mechanisms and sustainability performance remains underexplored.

Note on the product of the largest and the smallest eigenvalue of a graph

open access: yesSpecial Matrices
In this note, we use eigenvalue interlacing to derive an inequality between a graph’s maximum degree and its maximum and minimum adjacency eigenvalues. The equality case is fully characterized.
