Introduction: Phoenix showed the presence of ~1% perchlorate in the landing site regolith [1]. This ion is associated to sodium and magnesium [2], making these compounds ideal candidates for liquid brines on the surface. In addition, hydration-dehydration cycles may control the humidity. We study the stability of perchlorates (liquids and salts) under Martian conditions using a combination of e...

Network coordinate (NC) system allows efficient Internet distance prediction with scalable measurements. Most of the NC systems are based on embedding hosts into a low dimensional Euclidean space. Unfortunately, the accuracy of predicted distances is largely hurt by the persistent occurrence of Triangle Inequality Violation (TIV) in measured Internet distances. IDES is a dot product based NC sy...

The Phoenix Zoo is currently housing three female wild-born Asian elephants (Elephas maximus) who came to us from other organizations with a variety of health and behavioral problems, some of which have been exasperated since arriving at our facility. Each of these elephants has had a troubled past and they were labeled as ‘problem animals’. The Phoenix Zoo, through various circumstances, acqui...

Mars is a natural laboratory for testing the physical and chemical processes that shape planetary surfaces under cold and arid climate conditions [1-3]. The Phoenix lander has discovered a wide range of chemical constituents [3-6] in samples of high latitude portions of the martian latitude-dependent mantle (LDM) [7, 8]. Critical questions remain as to whether the identified species formed in-s...
