Bees have a diversified natural history, thus the methods applied to study such diversity are varied.When it comes to studies of nesting biology, bees which nest in pre-existing cavities have been reasonably well studied since researchers started using trap-nests.However, bees whose nests are built underground are poorly studied due Coats to the di

Abstract Background Mesenchymal stem cells (MSCs) are considered to be an effective tool Kids hats for regenerative medicine with promising applications for clinical therapy.However, incongruent data has been reported partially owing to their functional heterogeneity.To provide sufficient and suitable clinical seed cells derived from the placenta f

Given the imaging characteristics of synthetic aperture radar (SAR) images and the inherent speckle noise in them, scale-invariant feature transform based algorithms are unable to perform satisfactorily.To improve registration efficiency between SAR images, we propose a robust and efficient registration method with three main contributions.First, c
