Phosphate minerals, which are ubiquitous in terrestrial and extra-terrestrial rocks, are important carriers of trace elements, including U and Th, which provide chronological information because of t...
We consider equivariant solutions for the Schr¨odinger map problem from R2+1to H2 with finite energy and show that they are global in time and scatter.
Here we describe a new trait-based model for cellular resource allocation that we use to investigate the relative importance of different drivers for small cell size in phytoplankton. Using the model...
We investigated the spatial variability of picocyanobacterial community structure across the Costa Rica Dome(CRD), an offshore upwelling system characterized by high seasonal abundance of Synechococcu...
Studies in artificially confined, small-scale experimental systems with a homogeneous prey distribution suggest that selectivity in planktivorous fish for more conspicuous and rewarding prey (such as...
We report a study of DNA deformations using a coarsegrained mechanical model and quantitatively interpret the allosteric effects in protein−DNA binding affinity. A recent single-molecule study (...
Small unmanned aerial vehicles are increasingly being employed for environmental monitoring at local scale, which drives the demand for compact and lightweight spectral imagers. This paper describes t...
Place names play an important role in Borderlands Situation topics, while current focused crawling methods treat them in the same way as other common keywords, which may lead to the omission of many u...
There are hundreds of spatial reference frame (SRF) being applied, and the great difference among SRFs has blocked the share of global data on planet Earth. A conceptual spheroid of radius 12,800km a...
Trace metals in the surface sediments were measured to investigate the spatial distribution and annual variations of metals (Cr, Co, Ni, Cu, Zn, As, Cd, Pb, Hg) and to evaluate the pollution status f...
Geochemical mapping of 87Sr/86Sr ratios in Shikoku Island and the Kii Peninsula of Southwest Japan was performed using 233 samples of stream sediments (<180 μm). The spatial distribution of 87Sr/86Sr...
Slow-moving landslides (earth flows) can dominate hills lope sediment flux and landscape erosion in hilly terrain with mechanically weak, fine-grained rock. Controls on the occurrence of slow-moving ...
Slow-moving landslides (earthfl ows) can dominate hillslope sediment fl ux and landscape erosion in hilly terrain with mechanically weak, fi ne-grained rock. Controls on the occurrence of slow-moving ...
Nearly 15,000 shallow, saline or freshwater lakes and ponds coexist in close proximity in the Nhecolaˆndia, a 24,000 km2 subregion of the Pantanal wetland in Brazil. This study aims to understa...
For 173477 epicenters of earthquakes with М ≥ 4.5, which occurred at the globe in 1973-2010, the geomagnetic Z-component in Geocentric Solar Magnetospheric (GSM) coordinate system were evaluated for t...
