To offer location-based services, service providers need to have access to Location Information (LI) regarding the users which they wish to serve; this is a potential privacy threat. Constraints, i.e. statements limiting the use and distribution of LI, that are securely bound to the LI, have been proposed as a means to reduce this threat. However, constraints may themselves reveal information t...

Stars destroy lithium (Li) in their normal evolution. The convective envelopes of evolved red giants reach temperatures of millions of K, hot enough for the Li(p, α)He reaction to burn Li efficiently. Only about 1% of first-ascent red giants more luminous than the luminosity function bump in the red giant branch exhibit A(Li) > 1.5. Nonetheless, Li-rich red giants do exist. We present 15 Li-ric...

The inhomogeneous Li electrodeposition of lithium metal electrode has been a major impediment to the realization of rechargeable lithium metal batteries. Although single ion conducting ionomers can induce more homogeneous Li electrodeposition by preventing Li(+) depletion at Li surface, currently available materials do not allow room-temperature operation due to their low room temperature condu...

The objective of the present work is to study the casting characteristics of various A1-Li alloys, which include fluidity and strengths of the alloys and their interaction with cast molds. Materials investigated are Al-Li-Mg and Al-Li-Cu-Mg alloys with Li content of 2.5 wt%. The results show that sand molds with resin binders are good for A1-Li casting. Ceramic coatings can further reduce the m...

COCA (Collaborative Objects Coordination Architecture) was proposed as a novel means to model and support collaborations over the Internet. Our approach separates coordination policies from user interfaces and the policies are speci ed in a logic-based language. Over the past year, both the collaboration model and the speci cation language have been substantially re ned and evaluated through ou...

The present study investigated whether peroxynitrite (ONOO)-elicited cytotoxicity on human brain vessel smooth muscle cells (HBVSMCs) was related to alteration in programmed cell death 4 (PDCD4) gene expression. Cell viability, morphological changes and apoptosis were determined by methylthiazoletetrazolium (MTT) assay, acridine orange staining and flow cytometry, respectively. Expressions of P...
