Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

Advanced Science, EarlyView.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

Fuzzy computation on ensemble deep network for the performance of vampire attack detection model in WSN

EURASIP Journal on Wireless Communications and Networking
Context Wireless sensor network (WSN) is susceptible to vampire attacks. It is a type of denial of service (DoS) attack that drains sensor nodes’ energy, leading to network failure. The study addresses the challenge by detecting these attacks to conserve

Breaking the Bottleneck in Limit of Detection of Surface Refractive Index Sensing by Harnessing Meta‐Waveguide Microring Resonators

Advanced Science, EarlyView.
Mode splitting in meta‐waveguide microring resonators (MWMRs) effectively suppresses baseline drift and measurement noise while maintaining high refractive‐index sensitivity. This reflection‐induced mode splitting strategy enables quantitative detection of ultra‐weak surface perturbations and establishes MWMRs as a robust, drift‐immune platform for ...
