We present here numerical simulations of surface solar convection which cover a box of 30 x 30 x 3.2 Mm(3) with a resolution of 315 x 315 x 82, which is used to investigate the dynamics of scales larger than granulation. No structure resembling supergranulation is present; possibly higher Reynolds numbers (i.e. higher numerical resolution), or magnetic fields, or greater depth are necessary. The r
A simulation model of the adaptive optics of the German Vacuum Tower Telescope (VTT), Observatorio del Teide, Tenerifes presented. The model uses modules from the integrated model of the Euro50 extremely large telescope, and includes submodels of a Shack-Hartmann wavefront sensor, a de-formable mirror, a tip-tilt mirror, high-voltage amplifier low-pass filters, a reconstructor and a controller. We
We show that the Galactic thick disk reaches at least solar metallicities and that it experienced strong chemical enrichment during a period of ~3 Gyr, ending around 8-9 Gyr ago. This finding puts further constraints on the relation and interface between the thin and thick disks and their formation processes. Our results are based on a detailed elemental abundance analysis of 261 kinematically sel
Stars form in clusters or groups. In these crowded environments, they are likely to experience encounters with one another. These encounters may perturb their planetary systems and cause the ejection of one or more planets. N-body simulations were performed to study the effect of encounters between stars on their planetary systems in young stellar clusters. Two categories of young clusters were mo
Repetitive DNA is quantitatively the main component of telomeres and centromeres, structures responsible for maintenance of the eukaryotic chromosome. The telomere is the specialized nucleoprotein complex that terminates linear chromosomes. In most species the DNA component consists of short repeats which are generated by the enzyme complex telomerase. However, there are important exceptions such
Gene expression profiling of tumors using DNA microarrays is a promising method for predicting prognosis and treatment response in cancer patients. It was recently reported that expression profiles of sporadic breast cancers could be used to predict disease recurrence better than currently available clinical and histopathological prognostic factors. Having observed an overlap in those data between
Lunds Civila Ryttarförening, LCR, is one of Sweden’s largest equestrian clubs with its facilities located in between Norra Fäladen to the north and LTH to the south. To the west of the horse facilities is “Smörlyckans Idrottsplats” with football pitches, tennis courts, a Jujutsu club and a Home Guard’s building. The club has approximately 500 weekly riders and offers a wide range of activities wit
An analog of Quantum Chromo Dynamics (QCD) sector known as mirror QCD (mQCD) can affect the cosmological evolution due to a non-trivial contribution to the Cosmological Constant analogous to that induced by the ground state in non-perturbative QCD. In this work, we explore a plausible hypothesis for trace anomalies cancellation between the usual QCD and mQCD. Such an anomaly cancellation between t
The proton has a substructure in terms of parton cascades, which in a high energy collision fills the whole rapidity range between projectile and target. In the Good–Walker formalism the fluctuations in the cascades will give rise to diffractive excitation. Within the Lund Dipole Cascade model, it is in this way possible to reproduce diffractive excitation in pp collisions and DIS. In central pp c
A short review is presented for the most commonly used general purpose event generators for heavy ion physics, HIJING, AMPT, and EPOS. A new model, called Angantyr, is presented. It is (similar to HIJING) an extrapolation of pp dynamics to collisions with nuclei. Diffractive excitation of individual nucleons has significant effects in nucleus collisions, and here Angantyr is the first model which
We discuss the dark phases of the Next-to-2-Higgs Doublet model. The model is an extension of the Standard Model with an extra doublet and an extra singlet that has four distinct CP-conserving phases, three of which provide dark matter candidates. We discuss in detail the vacuum structure of the different phases and the issue of stability at tree-level of each phase. Taking into account the most r
Background Murray's Law states that, when a parent blood vessel branches into daughter vessels, the cube of the radius of the parent vessel is equal to the sum of the cubes of the radii of daughter blood vessels. Murray derived this law by defining a cost function that is the sum of the energy cost of the blood in a vessel and the energy cost of pumping blood through the vessel. The cost is minim
We consider the impact of multi-parton interactions and colour reconnection on the modeling of vector boson fusion and vector boson scattering (VBS) final states at the Large Hadron Collider (LHC). We investigate how the variation of the model parameters, compatible with a reasonable spread of predictions around typical tuning observables, extrapolates into the VBS phase space. We study the implic
A series of previous papers develops a dipole model in initial state impact parameter space that includes subleading effects such as running alpha strong, unitarity, confinement and saturation. Here some recent work is presented, where the model is applied to a new set of data: vector meson production in photon-proton, DVCS and t-dependence in elastic proton-proton collisions. This allows us to tu
