Rab-interacting lysosomal protein (RILP) is a regulator of late stages of endocytosis. Recent work proved that depletion of RILP promotes migration of breast cancer cells in wound healing assay, whereas its overexpression influences re-arrangements of actin cytoskeleton. Here, we further characterized the role of RILP in cell migration by analyzing several aspects of this process. We showed tha...

Seismic migration requires an accurate background velocity model that correctly predicts the kinematics of wave propagation in the true subsurface. Least-squares migration, which seeks the inverse rather than the adjoint of a forward modeling operator, is especially sensitive to errors in this background model, which can result in traveltime differences between predicted and observed data that ...

Although numerous workers, especially Northrop and DeKruif (1922) and Winslow, et al. (1923 and 1926), have studied the influence of electrolytes upon the electrophoretic migration velocity of bacteria by washing them free of their metabolic products and suspending them in solutions of the electrolytes, little attention has been given to the effect upon electrophoretic potential of electrolytes...

We analyze the kinematic properties of offset-domain Common Image Gathers (CIGs) and Angle-Domain CIGs (ADCIGs) computed by wavefield-continuation migration. Our results are valid regardless of whether the CIGs were obtained by using the correct migration velocity. They thus can be used as a theoretical basis for developing Migration Velocity Analysis (MVA) methods that exploit the velocity inf...

A simple zero-velocity method to determine the particle magnetic susceptibility by measuring the magnetophoretic velocity was proposed. The principle is that the magnetophoretic velocity of a particle in a liquid medium must be zero when the magnetic susceptibilities of the medium and the particle are equal, or the gravity force and the magnetophoretic force are balanced. By changing the medium...

The main objective of this thesis is to study new methods for estimating the macro velocity model, which controls the wave kinematics, in the context of reflection seismology. Migration velocity analysis evaluates the quality of the velocity model used for imaging seismic data by comparing images of the subsurface structures as a function of extension parameters, such as offset, reflection angl...

If the velocity of the medium is known and the medium does not incorporate different reflectors that have identical surface seismic measurements that remain identical under small perturbations of the medium, map migration achieves a one-to-one correspondence between the reflections recorded at the surface, and the reflectors in the subsurface, through explicit use of the slopes in the data.
