In this paper, we analyze the way in which international Facebook users who had recently moved to the United States used different languages to selectively self-disclose to their old (native-language) and new (English-speaking) social circles. We found significantly more intimate self-disclosure, covering a broader range of cognitive and emotional topics,(More)
In distant collaborations, interruptions increase significantly due to the limited awareness of colleagues' availability. In this paper we evaluate OpenMessenger, an instant messaging prototype that provides awareness information. Results suggest that the use of OM benefits group task performance and the social attraction developed between group members.(More)
We have studied the competitive entry of potassium and sodium into carbon nanotubes using molecular dynamics simulations. Our results demonstrate how a combination of strong sodium hydration coupled with strong potassium-chlorine interaction leads to enhanced potassium selectivity at certain diameters. We detail the reasons behind this, and show how(More)
The ion selective transport plays an important role in the function of cell membranes, and promotes the application of artificial permeable membranes. This phenomenon has been studied in case for different diameters and functional groups of nanopores. In this work, we focus on the effect of anions on cation selectivity, in particular the influence of(More)
Advanced malignant ascites is accompanied by gastrointestinal dysmotility, and patients often feel abdominal pain, abdominal distention, nausea and constipation. Gastrointestinal dysmotility is not only painful for the patients, but it reduces the absorption of nutrients and affects the physical recovery of patients with malignant ascites. It is reported(More)
Water transport through aquaporin water channels occurs extensively in cell membranes. Hourglass-shaped (biconical) pores resemble the geometry of these aquaporin channels and therefore attract much research attention. We assumed that hourglass-shaped nanopores are capable of high water permeation like biological aquaporins. In order to prove the(More)
