Researchers new minor planets beyond Neptune
2020/3/27
Using data from the Dark Energy Survey, National Science Foundation-funded researchers at the University of Pennsylvania have found more than 300 objects beyond Neptune, minor planets located in the f...
Seismogenesis in Central Apennines,Italy:an integrated analysis of minor earthquake sequences and structural data in the Amatrice-Campotosto area
seismic hazard normal faulting seismicity seismotectonics active stress
2015/9/11
We present a seismotectonic study of the Amatrice-Campotosto area (Central Italy) based on an integrated analysis of minor earthquake sequences, geological data and crustal rheology. The area has been...
Large ionospheric disturbances during a minor geomagnetic storm on June 23,2000
Ionospheric storm Minor geomagnetic disturbance Energy transfer
2015/8/24
We investigate the variations in the ionosphere during a small geomagnetic storm on June 23, 2000, using the total electron content of the Jet Propulsion Laboratory global positioning system, and the ...
Influence of plant-associated microbial communities on heavy metal uptake by the aquatic plant Lemna minor
Aquatic plants bacteria heavy metal duckweed aquatic plants pollution of bacteria plants
2015/1/28
We present research aimed at determining how bacteria associated with aquatic plants influence phytoextraction of heavy metals. We focused on the aquatic plant Lemna minor and its response to cadmium ...
COLUMBUS, Ohio: Astronomers have gotten the closest look yet at what happens when a black hole takes a bite out of a star—and the star lives to tell the tale.
The Minor inequalities in the description of the Set Covering Polyhedron of Circulant Matrices
polyhedral combinatorics set covering circulant matrices Combinatorics
2012/6/25
In this work we give a complete description of the set covering polyhedron of circulant matrices $C^k_{sk}$ with $s = 2,3$ and $k\geq 3 $ by linear inequalities. In particular, we prove that every non...
Reddening and metallicity maps of the Milky Way Bulge from VVV and 2MASS. I.The method and minor axis maps
Galaxy: bulge - ISM: dust, extinction - stars: abundances
2011/10/18
We present a method to obtain reddening maps and to trace structure and metallicity gradients of the bulge using data from the recently started ESO public survey Vista Variables in the Via Lactea (VVV...
Galaxy Zoo: Dust lane early-type galaxies are tracers of recent, gas-rich minor mergers
galaxies: evolution — galaxies: interactions — galaxies: active — galax-ies: elliptical and lenticular
2011/10/17
We present the second of two papers concerning the origin and evolution of local early-type galaxies exhibiting dust features. We use optical and radio data to examine the nature of AGN activity in th...
A WFC3 study of globular clusters in NGC 4150 - an early-type minor merger
galaxies: star clusters - galaxies: individual: NGC 4150 - galaxies: ellipti-cal and lenticular, cD - galaxies: evolution galaxies: interactions - ultraviolet: galaxies
2011/10/19
We combine near-ultraviolet (NUV; 2250 {\AA}) and optical (U, B, V, I) imaging from the Wide Field Camera 3 (WFC3), on board the Hubble Space Telescope (HST), to study the globular cluster (GC) popula...
Quantum query complexity of minor-closed graph properties
Quantum query minor-closed graph properties
2010/11/8
We study the quantum query complexity of minor-closed graph properties, which include such problems as determining whether a graph is planar, is a forest, or does not contain a path of a given length....
We de ne the limiting density of a minor-closed family of simple graphs F to be the smallest
number k such that every n-vertex graph in F has at most kn(1+o(1)) edges, and we investigate
the set of ...
Comprehensive analysis for major, minor and trace element contents and Sr-Nd-Pb-Hf isotope ratios in sediment reference materials, JSd-1 and MAG-1
Sediment standard JSd-1 MAG-1 trace elements Sr-Nd-Pb-Hf isotope ratios
2017/8/9
In view of the requirement of a well-characterized and easily available aquatic sediment reference material, a comprehensive analysis comprising of fifty major, minor and trace elements as well as Sr-...
