Abstract Insect eggshells must meet various demands of developing embryos.These demands sometimes conflict with each other; therefore, there are tradeoffs between eggshell properties, such as robustness and permeability.To meet these conflicting demands, particular eggshell structures have evolved in diverse insect species.Here, we report a rare eg
In energy harvesting Internet of Things (IoT) systems, the age of information (AoI) should be maintained at a low level to guarantee the accuracy and reliability of derived decisions.In this paper, we design an information freshness-guaranteed and energy-efficient data generation control system (IFE-DGCS) where an IoT gateway with a directional ant
Based on the static analysis, dynamic model of C80 heavy haul train was built to investigate the influence of partial load on running safety of heavy haul train.Under the different partial load condition, the derailment coefficient and the wheel load Omegas reduction rate were calculated when the train passed the curve.The analysis results show tha
Influenza A virus causes annual epidemics and occasional pandemics of short-term respiratory infections associated with considerable morbidity and mortality.The pandemics occur when new human-transmissible viruses that have the major surface protein of influenza A viruses from other host species are introduced into the human population.Between such
