The biological process of aging is believed to be the result of an accumulation of cellular damage to biomolecules. Although there are numerous studies addressing mutation frequencies, morphological or transcriptional changes in aging mammalian tissues, few have measured global changes at the protein level. Here, we present an in depth proteomic analysis of three brain regions as well as heart ...

Time-sensitive Wireless Sensor Network (WSN) applications require finite delay bounds in critical situations. This paper provides a methodology for the modeling and the worst-case dimensioning of clustertree WSNs. We provide a fine model of the worst-case cluster-tree topology characterized by its depth, the maximum number of child routers and the maximum number of child nodes for each parent r...

The addition of iron to high-nutrient low-chlorophyll (HNLC) oceanic waters stimulates phytoplankton, leading to greater primary production. Large-scale artificial ocean iron fertilization (OIF) has been proposed as a means of mitigating anthropogenic atmospheric CO(2), but its impacts on ocean ecosystems below the photic zone are unknown. Natural OIF, through the addition of iron leached from ...

We have used the Wide Field Planetary Camera 2 on theHubble Space Telescope to image a star field in the wing of the Small Magellanic Cloud (SMC), near the H ii region N81. The images were taken in the F336W, F547M, F675W, and F814W filters. From photometry of stars in this field, we construct color-magnitude diagrams (CMDs) for about 4200 stars and compare them with theoretical isochrones. In ...

[1] Seawater dissolved iron isotope ratios (dFe) have been measured in the North Atlantic near Bermuda. In a full-depth profile, seawater dissolved dFe is isotopically heavy compared to crustal values throughout the water column (dFeIRMM-014 = +0.30‰ to +0.71‰). Iron isotope ratios are relatively homogenous in the upper water column (between +0.30‰ to +0.45‰ above 1500 m), and dFe increases bel...

A conceptual model of the Taupo Volcanic Zone (TVZ) is developed, to a depth of 25 km, formed from three constant density layers. The upper layer is formed from eruption products. A constant rate of eruption is assumed, which eventually implies a constant rate of extension, and a constant rate of volumetric creation in the middle and bottom layers. Tectonic extension creates volume which can ac...

The transformation of mature (urbanized) phase the ancient Indus civilisation between ?4200 and 3800 years Before Present (yr BP) overlaps with beginning Meghalayan Age (?4200 ± 100 yr BP). Though exact cause(s) for decline urbanized are not yet clear, researchers continue to debate whether monsoonal dryness was sole cause or several other regional factors manifested in a compounding manner. He...
