2014/12/26
We present Submillimeter Wave Astronomy Satellite observations of water vapor in two cold starless clouds, B68 and core D in ρ Ophiuchi. Sensitive nondetections of the 110-101 transition of o-H2O are ...
Galaxies in a simulated Lambda CDM Universe - I. Cold mode and hot cores
cooling fl ows feedback cluster
2014/12/23
We study the formation of galaxies in a large volume (50 h−1 Mpc, 2 × 2883 particles) cosmological simulation, evolved using the entropy and energy-conserving smoothed particle hydrodynamics (SP...
THE MASS DISTRIBUTION OF STARLESS AND PROTOSTELLAR CORES IN GOULD BELT CLOUDS

2014/12/22
Using data from the SCUBA Legacy Catalogue (850 μm) and Spitzer Space Telescope (3.6-70 μm), we explore dense cores in the Ophiuchus, Taurus, Perseus, Serpens, and Orion molecular clouds. We develop a...
Downscale cascades in tracer transport test cases: an intercomparison of the dynamical cores in the Community Atmosphere Model CAM5
tracer transport test cases the dynamical cores Community Atmosphere Model CAM5
2014/12/10
The accurate modeling of cascades to unresolved scales is an important part of the tracer transport component of dynamical cores of weather and climate models. This paper aims to investigate the abili...
Hypoxic Cell Waves around Necrotic Cores in Glioblastoma: A Biomathematical Model and its Therapeutic Implications
Glioblastoma multiforme tumor hypoxia pseudopalisades invasion mathematical model
2012/5/2
Glioblastoma is a rapidly evolving high-grade astrocytoma that is distinguished pathologically from lower grade gliomas by the presence of necrosis and microvascular hiperplasia. Necrotic areas are ty...
Analysis of historical trend of carotenoid concentrations in sediment cores from Lake Shinji, Japan

2017/4/11
The historical trend of the concentrations of carotenoids originating from phytoplankton in sediment cores collected at
two sites in Lake Shinji, a eutrophic oligohaline lake was investigated to clar...

2011/10/20
Icy grain mantles are commonly observed through infrared spectroscopy toward dense clouds, cloud cores, protostellar envelopes and protoplanetary disks. Up to 80% of the available oxygen, carbon and n...
The Spitzer ice legacy: Ice evolution from cores to protostars
Spitzer ice legacy Ice evolution cores protostars
2011/10/20
Ices regulate much of the chemistry during star formation and account for up to 80% of the available oxygen and carbon. In this paper, we use the Spitzer c2d ice survey, complimented with data sets on...
Emission Measure Distribution and Heating of Two Active Region Cores
Emission Measure Distribution Heating Active Region Cores
2011/10/13
Using data from the Extreme-ultraviolet Imaging Spectrometer aboard Hinode, we have studied the coronal plasma in the core of two active regions. Concentrating on the area between opposite polarity mo...
Clustered Star Formation in Magnetic Clouds: Properties of Dense Cores Formed in Outflow-Driven Turbulence
Magnetic Clouds: Properties Dense Cores Formed Outflow-Driven Turbulence
2011/10/11
We investigate the physical properties of dense cores formed in turbulent, magnetized, parsec-scale clumps of molecular clouds, using three-dimensional numerical simulations that include protostellar ...

2011/2/28
We study minimal reductions of edge ideals of graphs containing a unique even cycle, and determine restrictions on the coefficients of the generators of these minimal reductions.
Chemical Variation in Molecular Cloud Cores in the Orion A Cloud
Chemical Variation Molecular Cloud Cores the Orion A Cloud
2011/1/10
We have observed molecular cloud cores in the Orion A giant molecular cloud (GMC) in CCS, HC3N, DNC, and HN13C to study their chemical characteristics. We have detected CCS in the Orion A GMC for the ...
The central slope of dark matter cores in dwarf galaxies: Simulations vs. THINGS

2010/11/15
We make a direct comparison of the derived dark matter (DM) distributions between hydrody-
namical simulations of dwarf galaxies assuming a CDM cosmology and the observed dwarf galaxies sample from ...
Spin-Density Wave near the Vortex Cores of Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$
Spin-Density Wave Vortex Cores
2010/11/18
Competition with magnetism is at the heart of high temperature superconductivity, most intensely felt near a vortex core. To investigate vortex magnetism we have developed a spatially resolved probe u...
CS Lines Profiles in Hot Cores
