Biological structural systems such as plant seedcoats, beak of woodpeckers or ammonites shells are characterized by complex wavy and re-entrant interlocking features.This allows to mitigate large deformations and deflect or arrest cracks, providing remarkable mechanical performances, much higher than those of the constituent materials.Nature-inspir
Pulmonary arterial hypertension is a progressive and ultimately life-limiting disease in which survival is closely linked to right ventricular function.The right Lubricants ventricle remains relatively understudied, as it is known to have key developmental and structural differences from the left ventricle.Here, we will highlight what is known abou
The ability to detect novel sounds in a complex acoustic context is crucial for survival.Neurons from midbrain through cortical levels adapt to repetitive stimuli, while maintaining responsiveness to rare stimuli, a phenomenon called stimulus-specific adaptation (SSA).The site of origin and mechanism of SSA are currently unknown.We used microiontop
This paper proposes a novel ultrawideband antenna with high gain and circular polarization.Its circular polarization can be easily changed to right-handed or left-handed.The antenna consists of four sophisticated antipodal Vivaldi antennas and an ultrawideband feeding network.The feeding network composes of four horizontal-to-vertical transitions,
