Abstract The Subglacial Antarctic Lakes Scientific Access (SALSA) Project accessed Mercer Lake using environmentally clean hot-water drilling to examine interactions among ice, water, sediment, rock, microbes and carbon reservoirs within the lake water column underlying sediments. A ~0.4 m diameter borehole was melted through 1087 of ice maintained over ~10 days, allowing observation properties...

The systematic development of reduced low-dimensional stochastic climate models from observations or comprehensive high dimensional climate models is an important topic for atmospheric low-frequency variability, climate sensitivity, and improved extended range forecasting. Recently, techniques from applied mathematics have been utilized to systematically derive normal forms for reduced stochast...

buffer (50 mmol/liter Tris-HC1, pH 7.5, containing 300 mmol of NaCl per liter). The BB values are significantly different in samples 1, 3, and 8, where the true MB activity is >40 U/liter. The remaining samples with <40 U of MB per liter do not show any significant carryover of MB to BB. We are in the process of changing the MB buffer-salt content; this will essentially eliminate the MB to BB c...

Myosin Va belongs to the unconventional myosin family that has been identified in many non-muscle tissues of vertebrates and invertebrates. All known myosins bind actin and produce mechanical force through ATP hydrolysis. Myosin Va is only expressed in melanocytes and in cells of the neuronal system (Mercer et al., 1991). In melanocytes it is part of the melanosome transport complex (Wu et al.,...

Training support vector machines (SVM) with indefinite kernels has recently attracted attention in the machine learning community. This is partly due to the fact that many similarity functions that arise in practice are not symmetric positive semidefinite, i.e. the Mercer condition is not satisfied, or the Mercer condition is difficult to verify. Previous work on training SVM with indefinite ke...
