We have developed the Monte Carlo simulation program Jewel 1.0 (Jet Evolution With Energy Loss), which interfaces a perturbative final state parton shower with medium effects occurring in ultrarelativistic heavy ion collisions. This is done by comparing for each jet fragment the probability of further perturbative splitting with the density-dependent probability of scattering with the medium. A...

A jet of a Newtonian liquid impacting on a wall at right angle spreads as a thin liquid sheet which preserves the radial symmetry of the jet. We report that for a viscoelastic jet (solution of polyethylene glycol in water) this symmetry can break; close to the wall, the jet cross section becomes faceted and radial steady liquid films (wings) form, which connect the cross-section vertices to the...

We present preliminary results of measurements of charged particle jet properties in proton-proton collisions at √ s = 7 TeV using the ALICE detector. Jets are reconstructed using anti − kT, kT and SISCone jet finding algorithms with resolution parameter R = 0.4 in the range of transverse momentum from 20 to 100 GeV/c in the midrapidity region (| η | < 0.5). The uncorrected charged jet spectra ...

Observations of the core of the giant radio galaxy NGC315 made with VLBI interferometers are discussed in the context of a relativistic jet. The sidedness asymmetry suggests Doppler favoritism from a relativistic jet. The presence of moving features in the jet as well as jet counter–jet brightness ratios hint at an accelerating, relativistic jet. An increasing jet velocity is also supported by ...

Azimuthal correlation functions are used to study jetand di-jet properties as a function of centrality in Au+Au collisions at √ s NN =200 GeV. Utilizing a novel technique to decompose the correlation function into a (di-)jet and an underlying event, the jet-pair distribution is extracted and compared to similar results for d+Au collisions obtained at the same collision energy. A striking simila...

Junctional ectopic tachycardia (JET) often occurs in the setting of surgery for congenital heart disease [1]. A congenital variety of JET not related to any surgery has also been described [2]. While post surgical JET has a mortality upto 14% [1], congenital JET has a mortality upto 34% [3]. A case of JET associated with myocarditis, has also been reported [4]. Electrocardiographic diagnosis of...

Context. Astrophysical jets from various sources seem to be stratified, with a fast inner jet and a slower outer jet. As it is likely that the launching mechanism for each component is different, their interface will develop differential rotation, while the outer jet radius represents a second interface where disruptions may occur. Aims. We explore the stability of stratified, rotating, relativ...

Numerical simulation has been performed by solving full Navier–Stokes equations governing the three-dimensional unsteady compressible flows. The main goal of the present work is to investigate the flow characteristics of a square jet issuing transversally into a cross-flow at three injection angles of 90°, 60° and 30°, and thus to provide some deeper insights into the physical flow mechanism go...

[1] The ISUAL gigantic jets (GJs) are categorized into three types from their generating sequence and spectral properties. Generating sequence of the type I GJs resembles that reported previously; after the fully developed jet (FDJ) established the discharge channel, the ISUAL photometers registered a peak that was from a return‐stroke‐like process. The associated ULF (ultra‐low‐frequency) sfer...
