Scatter factor : molecular characteristics and effect on the invasiveness of epithelial cells [PDF]

open access: yes, 1990
The generation of invasiveness in transformed cells represents an essential step of tumor progression. We have previously shown that MDCK epithelial cells, which are deprived of intracellular adhesion by the addition of anti-Arc-1/uvomorulin antibodies ...

Activation of Hepatocyte Growth Factor-Met Autocrine Loop Enhances Tumorigenicity in a Human Lung Adenocarcinoma Cell Line

open access: yesNeoplasia: An International Journal for Oncology Research, 2000
Hepatocyte growth factor (HGF) is a multifunctional cytokine with effects on the proliferation, motility, and differentiation of cells that express its receptor Met.

Li I and K I Scatter in Cool Pleiades Dwarfs [PDF]

open access: yes, 2010
We utilize high-resolution (R~60,000), high S/N (~100) spectroscopy of 17 cool Pleiades dwarfs to examine the confounding star-to-star scatter in the 6707 Li I line strengths in this young cluster.

A Multivariable Method for Calculating Failure Probability of Aeroengine Rotor Disk

open access: yesAerospace, 2023
The probabilistic damage tolerance analysis of aeroengine rotor disks is essential for determining if the disk is safe. To calculate the probability of failure, the numerical integration method is efficient if the integral formula of the probability ...

Front-End Design for SiPM-Based Monolithic Neutron Double Scatter Imagers

open access: yesSensors, 2022
Neutron double scatter imaging exploits the kinematics of neutron elastic scattering to enable emission imaging of neutron sources. Due to the relatively low coincidence detection efficiency of fast neutrons in organic scintillator arrays, imaging ...

Mass-Temperature Relation of Galaxy Clusters: A Theoretical Study [PDF]

open access: yes, 2001
Combining conservation of energy throughout nearly-spherical collapse of galaxy clusters with the virial theorem, we derive the mass-temperature relation for X-ray clusters of galaxies $T=CM^{2/3}$.

Analytical Formula for the total scatter factor of the Small Radiation Field Size [PDF]

open access: yesJournal of Research in Applied and Basic Medical Sciences, 2021
Background & Aims:  We present an analytical formula (AF) to calculate the total scatter factor of the MLC-shaped small radiation beams. Materials & Methods: Pinpoint, Semiflex, and Farmer ion chambers were used for MLC/Jaw-shaped fields extending from ...

Evidence for Correlated Titanium and Deuterium Depletion in the Galactic ISM [PDF]

open access: yes, 2004
Current measurements indicate that the deuterium abundance in diffuse interstellar gas varies spatially by a factor of ~4 among sightlines extending beyond the Local Bubble.
