Modeling and Spatial Diversity-Based Receiving Improvement of In-Flight UAV FSO Communication Links
Applied Sciences, 2021 An in-flight unmanned aerial vehicle (UAV) free-space optical (FSO) communication channel model is proposed by considering the beam deviation of the UAV under different motion states and the phase distortion caused by atmospheric turbulences.

Spatial and evolutionary predictability of phytochemical diversity [PDF]
Proceedings of the National Academy of Sciences, 2021 Significance Phytochemical diversity affects plant fitness and is the source of numerous medicines. Despite this, we know remarkably little about how phytochemical diversity is distributed across the plant kingdom and the environment. To address this challenge, we coupled untargeted metabolomics on 416 grassland vascular plant species

Spatial diversity of spontaneous activity in the cortex. [PDF]
Front Neural Circuits, 2015 The neocortex is a layered sheet across which a basic organization is thought to widely apply. The variety of spontaneous activity patterns is similar throughout the cortex, consistent with the notion of a basic cortical organization. However, the basic organization is only an outline which needs adjustments and additions to account for the structural ...

Spatial modulation aided zero-padded single carrier transmission for dispersive channels [PDF]
, 2013 In this paper, we consider spatial modulation (SM) operating in a frequency-selective single-carrier (SC) communication scenario and propose zero-padding instead of the cyclic-prefix considered in the existing literature.
