ROV (Remotely Operated Vehicle) is a product of technological development, functioning to perform tasks in the water.Big tasks such as coral reef exploration, oil refineries, underwater monitoring, and sea accident rescue are carried out by such Peeler technology.ROV or unmanned submarines have 6 degrees of freedom, but for diving it requires only
Larvae of lacewings (Neuroptera) are known to be fierce predators.According to the morphology of fossil forms thisseems to have been the case already in the Early Cretaceous.While being predators, lacewing larvae are also food itemsfor other organisms.Here we report two pieces of amber from Myanmar providing instances of such cases.In one amberpiec
SUNGLASSES Interface dislocations may dramatically change the electric properties, such as polarization, of the piezoelectric crystals.In this paper, we study the linear interactions of two interface dislocation loops with arbitrary shape in generally anisotropic piezoelectric bi-crystals.A simple formula for calculating the interaction energy of t
Recent advances have enabled fast magnetic resonance imaging (MRI) of solid materials.This development Hazard Gaffer Tape has opened up new applications for MRI, but, at the same time, uncovered new challenges.Previously, MRI-invisible materials like the housing of MRI detection coils are now readily depicted and either cause artifacts or lead to a
