Hadronic resonance production with the ALICE experiment in pp and Pb-Pb collisions at LHC energies

Hadronic resonances $\mathrm{K}^{*}(892)^{0}$, $\phi$(1020) and $\Sigma(1385)^{\pm}$ have been measured by the ALICE experiment in pp collisions at $\sqrt{s}=7$ TeV and in Pb-Pb collisions at $\sqrt{s_{_\mathrm{NN}}}=2.76$ TeV. Transverse momentum spectra, particle ratios, nuclear modification factor and comparison with model predictions are discussed. In addition, ALICE results are compared with data obtained at RHIC energy.Comment: 3 pages, 3 figures, Proceedings of 16th Lomonosov Conference on Elementary Particle Physics, Moscow, 22/08/2013 - 28/08/201

Light modulation in planar aligned short-pitch deformed-helix ferroelectric liquid crystals

We study both experimentally and theoretically modulation of light in a planar aligned deformed-helix ferroelectric liquid crystal (DHFLC) cell with subwavelength helix pitch, which is also known as a short-pitch DHFLC. In our experiments, azimuthal angle of the in-plane optical axis and electrically controlled parts of the principal in-plane refractive indices were measured as a function of voltage applied across the cell. Theoretical results giving the effective optical tensor of a short-pitch DHFLC expressed in terms of the smectic tilt angle and the refractive indices of FLC are used to fit the experimental data. Optical anisotropy of the FLC material is found to be weakly biaxial. For both the transmissive and reflective modes, the results of fitting are applied to model phase and amplitude modulation of light in the DHFLC cell. We demonstrate that, if the thickness of the DHFLC layer is about 50 $\mu$m, the detrimental effect of field-induced rotation of the in-plane optical axes on the characteristics of an axicon designed using the DHFLC spatial light modulator in the reflective mode is negligible.Comment: 14 pages, 11 figure

Eliminating fuzzy duplicates in crowdsourced lexical resources

Collaboratively created lexical resources is a trending approach to creating high quality thesauri in a short time span at a remarkably low price. The key idea is to invite non-expert participants to express and share their knowledge with the aim of constructing a resource. However, this approach tends to be noisy and error-prone, thus making data cleansing a highly topical task to perform. In this paper, we study different techniques for synset deduplication including machine- and crowd-based ones. Eventually, we put forward an approach that can solve the deduplication problem fully automatically, with the quality comparable to the expert-based approach

Tungstate and Carbonate Ions Sorption Using Anion Exchangers AV-17-8 and Purolite A400

The current paper shows the results of tungstate and carbonate ion sorption using strongly basic anion exchangers AV-17-8 and Purolite A400. It has been established that anion exchanger AV-17-8 in the chloride form with parameters of 168 g of tungstate ion and 157 g of carbonate ion per 1 kg of anion exchanger has the maximum capacity for the tungstate and carbonate ions

Hadronic resonance production with ALICE at the LHC

We present recent results on short-lived hadronic resonances obtained by the ALICE experiment at LHC energies. Results include system-size and collision-energy evolution of transverse momentum spectra, yields and ratios of resonance yields to those of longer lived particles, and nuclear modification factors. The results are compared with model predictions and measurements at lower energies

Age-related differences in reaction time task performance in young children

Performance of reaction time (RT) tasks was investigated in young children and adults to test the hypothesis that age-related differences in processing speed supersede a “global” mechanism and are a function of specific differences in task demands and processing requirements. The sample consisted of 54 4-year-olds, 53 5-year-olds, 59 6-year-olds, and 35 adults from Russia. Using the regression approach pioneered by Brinley and the transformation method proposed by Madden and colleagues and Ridderinkhoff and van der Molen, age-related differences in processing speed differed among RT tasks with varying demands. In particular, RTs differed between children and adults on tasks that required response suppression, discrimination of color or spatial orientation, reversal of contingencies of previously learned stimulus–response rules, and greater stimulus–response complexity. Relative costs of these RT task differences were larger than predicted by the global difference hypothesis except for response suppression. Among young children, age-related differences larger than predicted by the global difference hypothesis were evident when tasks required color or spatial orientation discrimination and stimulus–response rule complexity, but not for response suppression or reversal of stimulus–response contingencies. Process-specific, age-related differences in processing speed that support heterochronicity of brain development during childhood were revealed

FORMATION AND DEVELOPMENT OF RESOURCE POTENTIAL OF THE RUSSIAN PENSION SYSTEM

Objective: This article examines he potential and resources available within the pension framework, highlighting the key financial mechanisms supporting individuals during times of job cessation or facing significant life risks.Methods: The study employs a social-dynamic approach, analyzing the components and financial strategies of the pension system through extensive forecasting and systemic analysis.Results: The study advocates for the adoption of a social-dynamic approach to evaluate and enhance the financial capabilities integral to the pension infrastructure. The concept and categorization of the resources and services within the pension scheme are introduced by the author. The analysis reveals that discrepancies and inconsistencies in understanding the pension framework's composition and fiscal strategies lead to operational flaws, conflicts, and instability.Conclusion: The study concludes that a revised pension framework must be adopted, emphasizing a hybrid model that incorporates both contributory and capital-funded schemes. This model should enhance the resilience of the pension system, ensuring its capability to meet the demands of current and future retirees and stabilize the financial foundation of the pension provision
