Direction modulation based on planar rectangular non‐linear frequency diverse array
Electronics Letters, 2023 Since its inception, the frequency diverse array (FDA) has attracted extensive attention and research because of its unique properties. However, most of the research primarily focuses on linear geometry FDA, with fewer studies on planar FDA.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Antenna Beampattern With Range Null Control Using Weighted Frequency Diverse Array
IEEE Access, 2020 The range-angle-dependent beampattern of frequency diverse array (FDA) makes it capable of dealing with range-dependent interference, which cannot be handled by conventional phased array. However, current publications pay more attention to the dot-shaped

A Short-Range Range-Angle Dependent Beampattern Synthesis by Frequency Diverse Array
IEEE Access, 2018 In this paper, we propose a new technique to generate a range-angle dependent transmit beampattern by introducing a nonlinear frequency modulation scheme based on arctangent function in the frequency diverse array (FDA) system. The propagation process of

RIPK4 function interferes with melanoma cell adhesion and metastasis
Molecular Oncology, EarlyView.RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Cognitive MIMO Frequency Diverse Array Radar with High LPI Performance
International Journal of Antennas and Propagation, 2016 Frequency diverse array (FDA) has its unique advantage in realizing low probability of intercept (LPI) technology for its dependent beam pattern. In this paper, we proposed a cognitive radar based on the frequency diverse array multiple-input multiple ...
