A Direct Construction of Inter-Group Complementary Code Set

IEEE Access, 2018
Complete complementary codes (CCCs) is a collection of mutually orthogonal complementary codes and Inter-group complementary (IGC) code set consists of multiple disjoint groups of 2-D codes.

Automatic Determination of Quasicrystalline Patterns from Microscopy Images

Advanced Intelligent Discovery, EarlyView.
This work introduces a user‐friendly machine learning tool to automatically extract and visualize quasicrystalline tiling patterns from atomically resolved microscopy images. It uses feature clustering, nearest‐neighbor analysis, and support vector machines. The method is broadly applicable to various quasicrystalline systems and is released as part of

Aperiodic quantum XXZ chains: Renormalization-group results

, 2005
We report a comprehensive investigation of the low-energy properties of antiferromagnetic quantum XXZ spin chains with aperiodic couplings. We use an adaptation of the Ma-Dasgupta-Hu renormalization-group method to obtain analytical and numerical results

Periodic and Statistically Distributed Surface Texturing of Surface‐Enhanced Raman Spectroscopy (SERS) Sensors with Spatially Selective Signal Mapping

Advanced Physics Research, EarlyView.
Molecular fingerprinting for the detection of biomolecules is highly sensitive and noninvasive through the surface‐enhanced Raman scattering (SERS) effect. This is a report on the commercially competitive performance of gold‐coated periodic structures and black Si (aperiodic) nanostructures as plasmonic SERS substrates.

Near-field-driven radiative thermal dynamics in aperiodic photonic nanostructures

JPhys Photonics
Harnessing structural correlations in near-field plasmonic and polaritonic systems hold untapped potential for controlling light–matter interactions at the nanoscale. By tuning these correlations, one can reshape mode localization, coupling, and spectral

Chaotic, mixed-mode and periodic oscillations during the electro-oxidation of copper in trichloroacetic acid [PDF]

Journal of the Serbian Chemical Society, 2004
The current oscillations of a copper electrode in trichloroacetic acid solutions were studied in this paper. The Cu/CCl3COOH system is a new electrochemical oscillator, showing rich dynamic behaviour on two controllable parameters: the trichloroacetic ...

New modelling technique for aperiodic-sampling linear systems

, 2010
A general input-output modelling technique for aperiodic-sampling linear systems has been developed. The procedure describes the dynamics of the system and includes the sequence of sampling periods among the variables to be handled.
