The first real-time profile control experiments integrating magnetic and kinetic variables were performed on DIII-D in view of regulating and extrapolating advanced tokamak scenarios to steady state devices and burning plasma experiments. The integrated model-based approach that was used is generic and is being developed under the framework of the International Tokamak Physics Activity for Inte...

In a recent pair of papers published in Cell, Gregor et al. provide an unprecedented glimpse into the dynamics of Bicoid (Bcd), a classical morphogen whose graded distribution along the anterior-posterior axis of the Drosophila embryo provides a key polarity cue guiding embryonic patterning (Gregor et al., 2007a, 2007b). With their data, the authors challenge the prevailing view of how the Bico...

In this paper, we describe the design of a profile generator toolkit, which aims to automatically create realistic user profiles for a mobile personalized portal service. These profiles simulate actual user behavior and are utilized to experiment with a personalized crawling system, called eRACE. With the help of this tool, we will assess the performance and scalability of the eRACE system by c...

introduction: the prevalence of hearing loss in neonates is 2-5 out of every 1,000 live births. global health committee, american academy of otolaryngology, and american academy of pediatrics have recommended that hearing loss in infants be identified, and treated when possible, prior to 6 months of age. this study was designed with the aim to screen the hearing of neonates in mashhad, iran. me...

The objective of this research is to examine the steady incompressible two-dimensional hydromagnetic boundary layer flow nanofluid passing through a stretched sheet in influence viscous and ohmic dissipations. present problem obtained with help an analytical technique called DTM-Pade Approximation. mathematical modeling considered form partial differential equation transformed into suitable sim...

Morphogen gradients are established by the localized production and subsequent diffusion of signaling molecules. It is generally assumed that cell fates are induced only after morphogen profiles have reached their steady state. Yet, patterning processes during early development occur rapidly, and tissue patterning may precede the convergence of the gradient to its steady state. Here we consider...

In human skin, two main populations of dendritic cells (DC) can be discriminated: dermal DC (DDC) and epidermal Langerhans cells (LC). Although extensively studied, most of the knowledge about DDC and LC phenotype and function is obtained from studying DDC and LC cultured in vitro or DDC and LC migrated from skin explants. These studies have left the exact relationship between steady-state huma...

We introduce and discuss spatially homogeneous Maxwell-type models of the nonlinear Boltzmann equation undergoing binary collisions with a random component. The random contribution to collisions is such that the usual collisional invariants of mass, momentum and energy do not hold pointwise, even if they all hold in the mean. Under this assumption it is shown that, while the Boltzmann equation ...

The relaxation-time limit from the quantum hydrodynamic model to the quantum drift-diffusion equations in R3 is shown for solutions which are small perturbations of the steady state. The quantum hydrodynamic equations consist of the isentropic Euler equations for the particle density and current density including the quantum Bohm potential and a momentum relaxation term. The momentum equation i...
