Delay performance in random-access grid networks [PDF]
, 2013 We examine the impact of torpid mixing and meta-stability issues on the delay performance in wireless random-access networks. Focusing on regular meshes as prototypical scenarios, we show that the mean delays in an $L\times L$ toric grid with normalized ...

Plasmonic Nanosensors and Metasensors Based on New Physical Mechanisms
Chemosensors, 2022 Plasmonics can bind light to their surface while increasing its intensity. The confinement and enhancement of light allows high–density, independent, subwavelength sensor elements to be constructed in micrometer–sized arrays.

Generation of the First-Order OAM Modes in Ring Fibers by Exerting Pressure Technology
IEEE Photonics Journal, 2017 We have proposed an effective method of generating the first-order orbital angular momentum (OAM) modes in ring fibers. The first-order OAM modes (${\rm{L = \pm 1}}$ ) can be represented as the linear superposition of the ${\rm{HE}}_{{21}}^{{\rm{even}}}$

2-D DOA tracking using variational sparse Bayesian learning embedded with Kalman filter
EURASIP Journal on Advances in Signal Processing, 2018 In this paper, we consider the 2-D direction-of-arrival (DOA) tracking problem. The signals are captured by a uniform spherical array and therefore can be analyzed in the spherical harmonics domain.
