To solve the information overload problem of multimodal answers in community question answering (CQA), this paper proposes a multimodal representative answer extraction method.First, the method of similarity calculation between multimodal answers is constructed, and multimodal clustering is used to cluster answers.Then, a binary multi-objective opt
Abstract Biohydrogen production through dark fermentation is very attractive as a solution to help mitigate the effects of climate change, via cleaner bioenergy production.Dark fermentation is a process where organic substrates are converted into bioenergy, driven by a complex community of microorganisms of different functional guilds.Understanding
Background and Purpose: This study aimed to identify the imaging characteristics and discriminate the etiology of acute internal carotid artery occlusion (ICAO) on computed tomography angiography (CTA) in patients with acute ischemic stroke.Materials and Methods: We retrospectively evaluated consecutive patients who underwent endovascular thrombect
Purifying selection during dengue viral infection has been suggested as the driving force of viral evolution and the higher complexity of the intra-host quasi-species is thought to offer an adaptive advantage for arboviruses as they cycle between arthropod and vertebrate hosts.However, very few studies have been performed to investigate the viral g
Abstract Dromaeosaurids were bird-like dinosaurs with a predatory ecology known to forage on fish, mammals and other dinosaurs.We describe Daurlong wangi gen.et sp.nov., a dromaeosaurid from the Lower Cretaceous Jehol Biota of Inner Mongolia, China.Exceptional farmhouse magnolia wreath preservation in this specimen includes a large bluish layer in
