Incorporating Emoji Descriptions Improves Tweet Classification

Description: Article presenting a simple strategy to process emojis in Tweets: replace them with their natural language description and use pretrained word embeddings as normally done with standard words. Results show that this strategy is more effective than using pretrained emoji embeddings for tweet classification.

Investigation of structural morphology and electrical properties of graphene-C₆₀ hybrids

Description: This article reports on the electrophoretic deposition of C₆₀ on graphene. The results suggest that graphene based C₆₀ structures are attractive as flexible transparent electrodes and are excellent electron accepting/charge transport materials for the construction of efficient photovoltaic devices.

Biocompatible, large-format, inkjet printed heterostructure molybdenum disulfide-graphene photodetectors on conformable substrates

Description: This article describes an inkjet printed, biocompatible, heterostructure photodetector that was constructed using inks of photo-active molybdenum disulfide (MoS2) and electrically conducting graphene which facilitated charge collection of the photocarriers. The importance of such devices stems from their potential utility in age-related-macular degeneration, which is a condition where the photosensitive retinal tissue degrades with aging, eventually compromising vision. The absence of effective… more

3D Atom Probe Tomography Study on Segregation of Yttrium in Modified Aluminum-Silicon Alloys

Description: In this article, yttrium segregation behavior in Al-Si alloys has been studied using the three-dimensional atom probe tomography technique. Al-Si alloys were prepared by casting method, and yttrium was added to modify the eutectic silicon morphology in these alloys. The results indicated that yttrium is preferentially located within the Si phase, with the highest concentration at the interface between eutectic Al and eutectic Si.

An experimental design to study decommitment in a collaborative multi-agent system in a scheduling domain

Description: This article describes the theoretical background and experimental design of new research based on previous multi-agent research on collaborative agents. The research extends the concept of agent decommitment into a resource scheduling domain. The problem is no longer time constrained, however, the number of agents is increased dramatically. The actual experimentation is yet to be performed. The authors state that results of the experimentation will be reported in a future article.
