We report the effect of the double Rayleigh backscattering (DRB) noise, in which the interference of the signal light with the double Rayleigh backscattered light, on the fiber-optic radio-frequency (RF) transfer system. Here, we theoretically analyze and experimentally demonstrate that the DRB nois...

This paper investigates the codebook design for the novel parallel dynamic subarrays for millimeter-wave (mmWave) massive MIMO systems. To generate high-resolution patterns, we design a novel parallel dynamic subarray structure where each radio frequency (RF) chain is dynamically connected to a suba...

Abstract Innovative groundwater management strategies are needed to preserve aquifers for crop irrigation. For sustainability to be lasting, any strategy must balance environmental goals with the economic aims of farmers. These tradeoffs are difficult to manage due to the inherent uncertainty in far...

Abstract Recent advances in urban climate modeling resolution have improved the representation of complex urban environments, with large‐eddy simulation (LES) as a key approach, capturing not only building effects but also urban vegetation and other critical urban processes. Coupling these ultrafine...

Existing CRISPR-based genome editing techniques for Bacillus subtilis (B. subtilis) are limited due to the large size of the cas gene. IscB, a recently reported DNA nuclease, is one-third the size of Cas9, making it a potential tool for genome editing; however, its application in B. subtilis remains...

Ralstonia spp. are highly adaptable bacteria that are widely distributed across diverse environments. Here, we isolated four Ralstonia pickettii (R. pickettii) genomes from cultures of Dolichospermum spp., and using a comparative genomic framework of 228 Ralstonia genomes. We performed phylogenetic...
