Rhinolophidae or Horseshoe bats emit long and narrowband calls.Fluttering insect prey generates echoes in which amplitude and frequency shifts are present, i.e.glints.These glints are reliable cues about the presence of prey and also encode certain properties of the prey.In this paper, we propose that these glints, i.e.the dominant glints, are also
ABSTRACTArbuscular mycorrhizal fungi (AMF) could establish symbiosis with plant roots, which enhances plant resistance to various stresses, including drought stress and salt stress.Besides AMF, chemical stimulants such as trehalose (Tre) can also play an important role in helping plants alleviate damage of adversity.However, the mechanism of the ef
Quenched and Tempered (Q&T) steels are widely used in the construction of military vehicles due to its high strength to weight ratio and high hardness.These steels are prone to hydrogen induced cracking (HIC) in the heat affected zone (HAZ) after welding.The use of austenitic stainless steel (ASS) 5318008 consumables to weld the above steel was the
ABSTRACT: An electromagnetic parametrically excited rolling pendulum energy harvester with self-tuning mechanisms subject to multi-frequency excitation is proposed and investigated in this paper.The system consists of two uncoupled rolling pendulum.The resonance frequency of each the liftmaster header bracket rolling pendulum can be automatically t
