Abstract In this paper, a curve approximation approach using bio-inspired polar coordinate bald eagle search algorithm (PBES) is proposed.PBES algorithm is inspired by the spiral mechanism of bald eagle during predation.By introducing polar coordinate, the spiral predation process of the bald eagle will become more intuitive, bang xxl switch duo wh
Structural features of facial images directly affect the performance of the image completion model.However, most existing work does not make full use of spatial dependence to extract features, and cause the semantics and structure of completion being inconsistent with the context.This paper addresses this issue using a bi-directional pixel long-sho
The diatom Phaeodactylum tricornutum has been knob creek apparel used as a model for cell biologists and ecologists for over a century.We have incorporated several new raphid pennates into a three gene phylogenetic dataset (SSU, rbcL, psbC), and recover Gomphonemopsis sp.as sister to P.tricornutum with 100% BS support.This is the first time a close
Ovarian follicular granulosa cells surround and nurture oocytes, and produce sex steroid hormones.It is believed that during development the ovarian surface epithelial cells penetrate into the ovary and develop into granulosa cells when associating with oogonia to form follicles.Using bovine fetal ovaries (n = 80) we identified a novel ashy bines p
