I present an algorithm to reconstruct direct regulatory interactions in gene networks from the effects of genetic perturbations on gene activity. Genomic technology has made feasible large-scale experiments that perturb the activity of many genes and then assess the effect of each individual perturbation on all other genes in an organism. Current experimental techniques can not distinguish betw...

One of the main challenges in autonomous manipulation is to generate appropriate multi-modal reference trajectories that enable feedback controllers to compute control commands that compensate for unmodeled perturbations and therefore to achieve the task at hand. We propose a data-driven approach to incrementally acquire reference signals from experience and decide online when and to which succ...

In this paper we report the observation of a natural generated internal particle transport barrier ( pITB ) in purely Ohmically heated plasmas in the HL-2A tokamak. The pITB have been observed when the line average electron density exceeds a threshold, which is nc=2.2×10m. The phenomenon is perfectly reproducible and identified by profile analysis, perturbative transport studies with Supersonic...

We make a theoretical study of the J/Ψ decays into ωππ, φππ, ωKK̄ and φKK̄ using the techniques of the chiral unitary approach stressing the important role of the scalar resonances dynamically generated through the final state interaction of the two pseudoscalar mesons. We also discuss the importance of new mechanisms with intermediate exchange of vector and axial-vector mesons and the role playe...

where Λ is the physical scale of the theory related to the running coupling αs = αs(Q ) at the scale Q. Since Λ has no expansion in αs, perturbative contributions are present only in W0, which from power counting is quartically divergent in the UV region. The term with the power Λ/Q is absent since there are no gauge invariant operators of dimension two. In the lattice theory all frequencies ar...

LLE Review, Volume 95 139 Introduction The compression of an inertial confinement fusion (ICF)1 target must achieve high hot-spot temperatures (T 10 keV) and shell areal densities (rR 300 mg/cm2) to ignite. An ICF implosion is subject to the Rayleigh–Taylor (RT)2,3 instability as the shell accelerates inward and as the shell decelerates toward stagnation, causing small perturbations in the shel...

Abstract. We study electromagnetic streaming instabilities in thermal viscous regions of rotating astrophysical objects, such as, protostellar and protoplanetary magnetized accretion disks, molecular clouds, their cores, and elephant trunks. The obtained results can also be applied to any regions of interstellar medium, where different equilibrium velocities between charged species can arise. W...

Jupiter and Saturn play host to an impressive array of satellites, making it reasonable to suspect that similar systems of moons might exist around giant extrasolar planets. Furthermore, a significant population of such planets is known to reside at distances of several Astronomical Units (AU), leading to speculation that some moons thereof might support liquid water on their surfaces. However,...

We performed computational reconstruction of the in silico gene regulatory networks in the DREAM3 Challenges. Our task was to learn the networks from two types of data, namely gene expression profiles in deletion strains (the 'deletion data') and time series trajectories of gene expression after some initial perturbation (the 'perturbation data'). In the course of developing the prediction meth...
