recommendations! Published in 2019 at "Circuits, Systems, and Signal Processing"

DOI: 10.1007/s00034-018-0976-4

Abstract: The small aperture microphone array becomes more and more popular in the consumer electronics. However, the small aperture usually limits the performance of the traditional DoA estimation methods. The differential microphone array (DMA) has attracted… read more here.

DOI: 10.1007/s11760-018-1396-4

Abstract: The traditional wideband direction-of-arrival (DOA) estimation algorithms usually require the preliminary DOA estimations, which determine the accuracy of the final DOA estimations. To remedy the apparent performance degradation, this paper introduces a novel direction-of-arrival (DOA)… read more here.

DOI: 10.1016/j.jinsphys.2017.01.005

Abstract: Mutations at the Darkener of Apricot (Doa) locus of Drosophila melanogaster alter sexual differentiation by disrupting sex-specific splicing of doublesex pre-mRNA, a key regulator of sex determination. Here, we study the effect of seven Doa… read more here.

DOI: 10.1016/j.psj.2021.101220

Abstract: Effects of the in ovo-injection of vitamin D3 (D3) and 25-hydroxyvitamin D3 (25OHD3) on broiler performance, carcass characteristics, and woody breast myopathy (WBM) incidence were investigated. Live embryonated Ross 708 broiler hatching eggs (2,880) were… read more here.

recommendations! Published in 2020 at "Scientific Reports"

DOI: 10.1038/s41598-020-69563-1

Abstract: MEMS acoustic sensors have been developed to mimic the highly-accurate sound-locating system of the Ormia ochracea fly, which detects sound wavelengths much larger than its hearing organ. A typical ormia-based MEMS directional sound sensor possesses… read more here.

recommendations! Published in 2020 at "International Journal of Electronics"

DOI: 10.1080/00207217.2020.1793403

Abstract: ABSTRACT It is interesting to determine the direction of arrival (DOA) of signals in the presence of impulsive noise for monostatic multiple-input multiple-output (MIMO) radar. Inspired by the robust statistics property of M-estimation theory and… read more here.

recommendations! Published in 2023 at "Measurement Science and Technology"

DOI: 10.1088/1361-6501/accdf8

Abstract: Uniform linear array (ULA) is commonly used for collecting underwater acoustic signals, and the direction-of-arrival (DOA) is obtained by array signal processing methods. The ULA-based multi-source DOA tracking suffers from the performance degradation caused by… read more here.

DOI: 10.1098/rspb.2022.1989

Abstract: ‘Evolve and resequence’ (E&R) studies in Drosophila melanogaster have identified many candidate loci underlying the evolution of ageing and life history, but experiments that validate the effects of such candidates remain rare. In a recent… read more here.

DOI: 10.1109/access.2018.2871028

Abstract: In this paper, we construct the generalized 3-D coprime array (G-TDCA) configuration, which consists of two 2-D uniform subarrays, by selecting three pairs of coprime integers to obtain the extension of inter-element spacing. Meanwhile, we… read more here.
