DOI: 10.1186/s40813-021-00195-1

Abstract: Background Genotypic variability in M. hyopneumoniae has been reported within and among herds. However, information regarding VNTR types within single lung lobes is lacking. The objective of his study was to analyse M. hyopneumoniae infections… read more here.

DOI: 10.1364/ol.449369

Abstract: In this paper, an optical phased array (OPA) with wide beam steering angle and low side-lobe level is designed based on the hybrid approach of particle swarm optimization (PSO) and convex optimization (CVX). The optimization… read more here.

DOI: 10.2528/pierc20060604

Abstract: In this paper, the performance of a concentric hexagonal antenna array (CHAA) is investigated with the exploitation of a robust variable diagonal loading (VDL) technique in the presence of direction of arrival (DOA) mismatch. The… read more here.
