First-principles investigation of dynamical properties of molecular devices under a steplike pulse
First-principles investigation dynamical properties of molecular devices
2010/11/22
We report a computationally tractable approach to first principles investigation of time-dependent current of molecular devices under a step-like pulse. For molecular devices, all the resonant states ...
Critical-doping universality for cuprate superconductors: Oxygen nuclear-magnetic-resonance investigation of Ca(x)La(1-x)Ba(1.75-x)La(0.25+x)Cu(3)O(y)
cuprate superconductors Oxygen nuclear-magnetic-resonance investigation
2010/11/18
The critical doping levels in cuprates, where the ground state changes its nature (from an an-
tiferromagnet to a spin glass to superconductor to metal), are not universal. We investigate the origin ...
A numerical stability investigation of strong ZND detonations for Majda's model
numerical stability investigation ZND Majda's model
2010/11/12
We carry out a systematic numerical stability analysis of ZND detonations of Majda's model with Arrhenius-type ignition function, a simplified model for reacting flow, as heat release and activation ...
Investigation for the enrichment pattern of the element abundances in r+s star HE 0338-3945: a special r-II star?
the enrichment pattern the element abundances r+s star HE 0338-3945
2011/1/10
The very metal-poor star HE 0338-3945 shows a double-enhanced pattern of the neutron-capture elements. The study to this sample could make people gain a better understanding of s- and r-process nucleo...
Experimental investigation of the predictive capabilities of data driven modeling techniques in hydrology - Part 1: Concepts and methodology
Experimental investigation the predictive capabilities data driven modeling techniques
2010/12/22
A comprehensive data driven modeling experiment is presented in a two-part paper. In this first part, an extensive data-driven modeling experiment is proposed. The most important concerns regarding th...
Investigation of Dynamics of Self-Similarly Evolving Magnetic Clouds
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
Magnetic clouds (MCs) are "magnetized plasma clouds" moving in the solar wind. MCs transport magnetic flux and helicity away from the Sun. These structures are not stationary but feature temporal evol...
An investigation of the close environment of beta Cep with the VEGA/CHARA interferometer
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
High-precision interferometric measurements of pulsating stars help to characterize their close environment. In 1974, a close companion was discovered around the pulsating star beta Cep using the spec...
Investigation of the hadronic interaction models using WILLI detector
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/27
The WILLI detector, built in IFIN-HH Bucharest, in collaboration with KIT Karlsruhe, is a rotatable modular detector for measuring charge ratio for cosmic muons with energy $<$ 1 GeV. It is under cons...
Investigation of the correlation between odd oxygen and secondary organic aerosol in Mexico City and Houston
the correlation odd oxygen and secondary organic aerosol Mexico City Houston
2010/10/11
Many recent models underpredict secondary organic aerosol (SOA) particulate matter (PM) concentrations in polluted regions, indicating serious deficiencies in the models' chemical mechanisms and/or mi...
An experimental investigation for external RC shear wall applications
An experimental investigation external RC shear wall applications
2010/10/21
The strength and rigidity of most reinforced concrete (RC) buildings in Turkey, which are frequently hit by destructive earthquakes, is not at a sufficient level. Therefore, the result of earthquakes ...

Micromorphology investigation of sepiolite bearing petrocalcic horizons formed from lacustrine sediments on the southern high planes of Texas and New Mexico
micromorphology investigation petrocalcic horizons lacustrine sediments
2011/11/8
The presence of sepiolite in soils has long been thought to have been attributed to inheritance from alternative parent material via secondary (eolian, alluvial) depositional processes due to sepiolit...
An investigation of the sub-grid variability of trace gases and aerosols for global climate modeling
the sub-grid variability trace gases and aerosols global climate modeling
2010/8/16
One fundamental property and limitation of grid based models is their inability to identify spatial details smaller than the grid cell size. While decades of work have gone into developing sub-grid tr...
Hygroscopic properties of Amazonian biomass burning and European background HULIS and investigation of their effects on surface tension with two models linking H-TDMA to CCNC data
Hygroscopic properties H-TDMA CCNC data surface tension
2010/8/13
HUmic-LIke Substances (HULIS) have been identified as major contributors to the organic carbon in atmospheric aerosol. The term "HULIS" is used to describe the organic material found in aerosol partic...
