Environmental Stressors Influence Spatial Complexity in a Fluvial Macrophyte meadow
Remote Sensing in Ecology and Conservation, EarlyView.This research investigates the nonlinear relationships between environmental stressors and the fine‐scale spatial complexity of a fluvial macrophytes meadow. The use of multivariate spatial analysis allowed us to identify two major environmental gradients (nutrients and light) and two major complexity gradients (related to abundance and fragmentation).

Investigation of EBG array performance on decreasing the mutual coupling and improve shield factor
Journal of Electrical Systems and Information Technology, 2015 In this paper EBG structures including parallel plates of EBGs are being used to reduce the mutual coupling between the two omni-directional antennas. Here, we have chosen the Discone antennas as omni directional antennas and comparisons between uniform ...

Small, EarlyView.This research demonstrates real‐time visualization of supramolecular sol‐gel transitions using Fluorescence Lifetime Imaging Microscopy (FLIM). By leveraging 5D visualization, integrating 3D space, time, and polarity resolution, we achieved maskless sub‐micrometric photopatterning within the gel matrix.

Analysis and design of Minkowski-like fractal antennas
Dianzi Jishu Yingyong, 2019 In order to achieve that an antenna works in ISM2.4G(2.4～2.483 5 GHz), Bluetooth,GPS,WLAN(2.4～2.48 GHz) and other multi-frequency band at the same time，the Minkowski fractal microstrip antenna based on the fractal theory is designed, and the original ...
