The growth of central and satellite galaxies in cosmological smoothed particle hydrodynamics simulations
theory formation
2014/12/23
We examine the accretion and merger histories of central and satellite galaxies in a smoothed particle hydrodynamics (SPH) cosmological simulation that resolves galaxies down to 7 × 109 M⊙. Most frien...
Growth of solid hcp 4He off the melting curve
Frozen pressure atomic solid melt curve cells transient temperature cells solidification
2014/12/19
We report studies of the growth of solid hcp 4He at pressures higher than the bulk freezing pressure using a cell design that allows us to inject atoms into the solid. Near the melting curve during in...
Mass flux and solid growth in solid 4He: 60 mK - 700 mK
Quartz glass rod solid dc magnetic flux flux waterfalls density and flow rate
2014/12/18
We use the thermo-mechanical effect to create a chemical potential difference between two liquid reservoirs connected to each other through Vycor rods in series with solid hcp 4He to confirm that a DC...
Invertebrate Phenology and Prey Selection of Three Sympatric Species of Salmonids; Implications for Individual Fish Growth
Invertebrate Phenology Prey Selection Three Sympatric Species Salmonids Individual Fish Growth
2014/12/12
Growth plays an important roll in the survival of individual salmonid fish. Diet inevitably plays a significant role in the determination of salmonid growth, with these diets consisting primarily of a...
Modulation of epidermal growth factor receptor function by mutations within the actin -binding domain
Genes actin internalization growth factors tyrosine phenylalanine glutamic acid phenylalanine residues
2014/12/11
The generation of site-directed mutants within the actin binding domain of the EGF receptor modulates receptor function in internalization and ligand binding. In addition, truncation of the EGFr at re...
Analysis of the interaction between the epidermal growth factor receptor and actin
Epidermal growth factor protein amino acids growth factors actin cell free system cytosol cells actin immune
2014/12/11
It has been shown that the epidermal growth factor receptor (EGFR) can directly interact with F-actin via an actin-binding domain (ABD) located at amino acid residues 984–996. In this study, we invest...
Estrogen and progesterone regulate p53 activity in the mouse mammary epithelium through transforming growth factor beta dependent pathways
P53 protein and tumor formation mammary gland p53 fertility estrogen and progesterone p53 radiation cells DNA damage
2014/12/11
Proper regulation of the p53 protein plays a critical role in suppressing tumor formation in a variety of tissues including the mammary gland. Activity of the p53 pathway is diminished in the mammary ...
Hormones, growth factors, and the regulation of tumor suppressor pathways involved in parity -induced protection of breast cancer
Women with breast cancer cases diagnosis and reproduction exogenous hormones ionizing radiation genetic factors
2014/12/11
Despite current advances in understanding breast cancer, in 2007 an estimated 178,480 new cases were diagnosed in female patients in the United States, and an estimated 40,640 deaths will occur due to...
Growth of galaxies in SPH simulations
Explore Galaxy formation. Smooth particle hydrodynamics The universe simulation Galactic gas Temperature history Galaxy star
2014/12/9
We explore the growth of galaxies formed in self-consistent Smoothed Particle Hydrodynamic (SPH) cosmological simulations. In the first Chapter, we examine the temperature history of gas accreted by f...
Adaptive method of lines for multi-component aerosol condensational growth and CCN activation
Adaptive method of lines multicomponent aerosol condensational growth CCN activation
2014/12/9
The process of formation of cloud droplets on an ensemble of aerosol particles is modelled by numerous investigators using the method of lines (MOL). The method involves discretisation of the aerosol ...
A Mathematical Growth Model of the Viral Population in Early HIV-1 Infections
HIV infection population genetics Viral dynamics
2014/12/8
In this thesis we develop a mathematical model to describe HIV-1 evolution during the first stages of infection (approximately within 40-60 days since onset), when one can assume exponential growth an...
