Accurate segmentation and evaluation of the anatomical and pathological features of retinal vessels are critical for the diagnosis and study of many ocular diseases. These include retinopathy of prematurity (ROP). ROP is a disorder of the retinal blood vessels that is a major cause of vision loss in premature neonates. It is proposed a methodology for extracting the vascular network in the huma...

section, a composite (deep-plane) rhytidectomy, and a subperiosteal face-lift. The results showed that the separate subcutaneous and sub-SMAS dissection interrupts the rich continuous anastomotic network between all these vessels. Arterial continuity is best maintained with the composite lift and the subperiosteal face-lift. The most significant arterial contribution of the face-lift flap is fr...

The intrinsic low conductivity of sulfur which leads to a low performance at a high current rate is one of the most limiting factors for the commercialization of lithium-sulfur battery. Here, we present an easy and convenient method to synthesize a mono-dispersed hollow carbon sphere with a thin graphitic wall which can be utilized as a support with a good electrical conductivity for the prepar...
