Motivated by recent successes on learning 3D feature representations, we present a Siamese network to generate representative 3D descriptors for 3D point matching in point cloud registration.Our system, dubbed HAF-Net, consists of feature extraction module, hierarchical feature reweighting and recalibration module (HRR), as well as feature aggregat
In recent years, microfiltration (MF) has gained great interest as an excellent technique for clarification of biological suspensions.This paper addresses a direct comparison of efficiency, performance and susceptibility to cleaning of the ceramic and polymeric MF membranes applied for purification of 1,3-propanediol (1,3-PD) fermentation broths an
During the last few decades it has been recognized that cell death is not King Sleigh Headboard the consequence of accidental injury, but is the expression of a cell suicide programme.Kerr et al.(1972) introduced the term apoptosis.This form of cell death is under the influence of hormones, growth factors and cytokines, which depending upon the rec
