Dielectric laser acceleration (DLA) is the technique utilizing strong electric fields in lasers to accelerate electrons in the proximity of nanoscaled dielectric gratings. The concept was recently demonstrated in experimental studies. Here, we describe the experimental DLA investigation setup design including laser system and scanning electron microscope (SEM). We also present the grating manuf...

We examine the branch structure of radial diffusion-limited aggregation (DLA) clusters for evidence of multifractality. The lacunarity of DLA clusters is measured and the generalized dimensions D(q) of their mass distribution is estimated using the sandbox method. We find that the global n-fold symmetry of the aggregates can induce anomalous scaling behavior into these measurements. However, ne...

After demonstrating their general expressions valid at all x, double differential 1-particle inclusive distributions inside a quark and a gluon jet produced in a hard process, together with the inclusive k⊥ distributions, are calculated at small x in the Modified Leading Logarithmic Approximation (MLLA), as functions of the transverse momentum k⊥ of the outgoing hadron. Results are compared wit...

Abrin, a galactose specific lectin was purified using sepharose 4B affinity column from seeds of Abrus precatorius. It exhibited antitumour activity in mice when used at a sublethal dose of 7.5 micrograms/kg every alternate day for 10 days. Both intralesional and intraperiloneal (i.p.) administration of abrin was effective in reducing solid tumour mass development induced by Dalton's Lymphoma A...

The galaxy giving rise to the damped Lyα absorbing system in the QSO OI 363 with z = 0.221 has been found. A galaxy which is probably associated with the second DLA in this same QSO at z = 0.0912 has also been found. Neither galaxy is very luminous, and neither galaxy shows signs of extensive current star formation, a massive disk or lots of gas. The impact parameters for each of the two galaxi...

In the recent years, several concurrent logical systems for reasoning about agency and social interaction and for representing game properties have been proposed. The aim of the present paper is to put some order in this ‘jungle’ of logics by studying the relationship between the dynamic logic of agency DLA and the game description language GDL. The former has been proposed as a variant of the ...

We use Sloan Digital Sky Survey Data Release 2 QSO spectra to constrain the dust-reddening caused by intervening damped Lyα systems (DLAs). Comparing the spectral index distribution of a 79 sight-line DLA sample with that of a large control sample reveals no evidence for dust-reddening at z∼3. Our limit on the shift in spectral index, |∆α|<0.14 (3 σ), corresponds to a limit on the colour excess...

A parallel algorithm for diffusion-limited aggregation (DLA) is described and analyzed from the perspective of computational complexity. The dynamic exponent z of the algorithm is defined with respect to the probabilistic parallel random-access machine (PRAM) model of parallel computation according to T ∼ L z , where L is the cluster size, T is the running time, and the algorithm uses a number ...

There is a variety of methods for ranking objectives in multiobjective optimization and some are difficult to define because they require information a priori (e.g. establishing weights in a weighted approach or setting the ordering in a lexicographic approach). In manyobjective optimization problems, those methods may exhibit poor diversification and intensification performance. We propose the...

We investigate some basic properties of Damped Lyman alpha systems based on the Semi-Analytical model of disk galaxy formation theory. We derive the DLA metallicity, column density, number density, gas content and cosmic star formation rate by assuming that disks form at the center of dark halos, and the modelled DLAs are selected by Monte Carlo simulation according to the distributions of halo...
