Short interspersed DNA elements and miRNAs: a novel hidden gene regulation layer in zebrafish?
In this study, we investigated by in silico analysis the possible correlation between microRNAs (miRNAs) and Anamnia V-SINEs (a superfamily of short interspersed nuclear elements), which belong to those retroposon families that have been preserved in vertebrate genomes for millions of years and are actively transcribed because they are embedded in the 3? untranslated region (UTR) of several genes. We report the results of the analysis of the genomic distribution of these mobile elements in zebrafish (Danio rerio) and discuss their involvement in generating miRNA gene loci.
Continuity properties of solutions to the p-Laplace system
A sharp integrability condition on the right-hand side of the p-Laplace system for all its solutions
to be continuous is exhibited. Their uniform continuity is also analyzed and estimates for their modulus
of continuity are provided. The relevant estimates are shown to be optimal as the right-hand side ranges in
classes of rearrangement-invariant spaces, such as Lebesgue, Lorentz, Lorentz-Zygmund, and Marcinkiewicz
spaces, as well as some customary Orlicz spaces.
Global existence and asymptotic stability of smooth solutions to a fluid dynamics model of biofilms in one space dimension
In this paper, we present an analytical study, in the one space dimensional case, of the fluid dynamics system proposed in [3] to model the formation of biofilms. After showing the hyperbolicity of the system, we show that, in an open neighborhood of the physical parameters, the system is totally dissipative near its unique non-vanishing equilibrium point.
CFD Maneuvering Prediction of a Twin Screw Vessel with Different Stern Appendages Configuration
The turning circle maneuver of a self-propelled tanker like ship model is numerically simulated through the integration of the unsteady Reynolds averaged Navier-Stokes (uRaNS) equations coupled with the equations of the motion of a rigid body. The solution is achieved by means of the unsteady RANS solver ?navis developed at CNR-INSEAN. The focus here is on the analysis of the maneuvering behavior of the ship with two different stern appendages configurations; namely, a twin screw with a single rudder and a twin screw, twin rudder with a central skeg.
ON THE MODULUS OF CONTINUITY OF SOLUTIONS TO THE n-LAPLACE EQUATION
Solutions to the n-Laplace equation with a right-hand side f are considered. We exhibit the largest rearrangement-invariant space to which f has to belong for every local weak solution to be continuous. Moreover, we find the optimal modulus of continuity of solutions when f ranges in classes of rearrangement-invariant spaces, including Lorentz, Lorentz-Zygmund and various standard Orlicz spaces.
