A tunable microwave absorption metamaterial inspired by moths evading bat detection
Electromagnetic radiation in the current environment has become complex and uncontrollable due to the advancement of wireless technology. Inspired by the moth surface cilia to bend and evade bat sonar detection, our work introduces a metamaterial incorporating broadband and tunable microwave absorption properties combined with deep learning algorithms.

Abstract Background Early enteral nutrition is recommended for critically ill patients. However, feeding an ischemic gastrointestinal tract with enteral nutrition may lead to gut necrosis. Although gut tolerance of enteral nutrition is assessed by various symptoms, none of them provide conclusive evidence of gut ischemia. We investigated the blood flow

Predicting potential Arctic kelp distribution and lower‐depth biomass from seafloor irradiance
Abstract Kelps have an extensive distribution in Arctic coastal waters. However, quantifying their role in the Arctic food web and carbon cycle is challenged by the scarcity of documented geographical distribution, standing stocks and production. Here we present a framework based on an empirical function to predict the potential kelp distribution and ...
