Despite the great progress made in the last decade, bioprinting still faces several challenges.
Despite the great progress, the synthesis of hollow core-shell nanostructure, especially ternary transition metal with core-in-hollow-shell nanostructure, is rarely reported.
Despite the great progress in their synthesis, a facile and scalable method is still highly appealing for the fabrication of NCs in one step, including the in situ N doping.
Despite the great progress, the user-friendliness of iris-based recognition systems is still a challenging issue and degrades significantly when iris images are affected by degradation factors such as motion blurriness, lack of focus, and eyelids and eyelashes occlusion.
Despite the great progress made in human-computer interaction, most of the existing interfaces are unidirectional and unfriendly in the sense that they do not allow the computer to understand the emotional state of the user [1 3].
Despite the great progress in nanotechnologies, comparatively little is known to date on the effects that exposure to NPs may have on the human body, in general and specifically on the brain.
Despite the great progress in NiO-based materials for supercapacitors in recent years, the tested specific capacitance of NiO-based materials is usually much lower than its theoretical specific capacitance.
Despite the great progress in the field of mesoporous silica materials, there are few reports on mesoporous spherical silica nanoparticles (MSSNPs) synthesized by hydrolysis and co-condensation of tetraethyl orthosilicate (TEOS) and n-octadecyltrimethoxysilane (C18TMS).
Despite the great progress on interactive image segmentation, image co-segmentation, 2D and 3D segmentation, there is still no workable solution to the problem: given a set of calibrated or un-calibrated multi-view images (say, more than 40 images), by interactively cutting 3 ∼ 4 images, can the foreground object of the rest images be quickly cutout automatically and accurately?
Despite the great progress made with the Voting Rights Act of 1965, we are backsliding at such rapid pace that it's scary to think where black participation in electoral politics might be if the trend continues.
