Prohibitions and Policy in the Global Gaming Industry: A Genealogy and Media Content Analysis of Gaming Restrictions in Contemporary Russia

In an era of widespread gaming expansion, Russia\u27s recent decision to contract its gaming industry stands out as a global anomaly. This article explores factors informing the 2009 restriction of gambling venues in Russia to four remote zones. After a brief discussion of gambling prohibition history across cultures, a genealogical analysis of the origins and development of gaming laws in Russia follows. The authors then use a qualitative content analysis technique to examine the rationales for this contraction that were expressed in Russian news outlets between 2003 and 2010 - the period when the new restrictions were debated, voted on, and enacted. This analysis revealed four major rationales cited by the media: 1) alleged ties between gambling and organized crime, 2) social cost themes associated with addiction and related problems with youth in Russia, 3) gambling\u27s enforcement of class boundaries, and 4) the protection of a Russian national identity. The results help us better understand anti-gambling arguments generally, and the unique dynamics of Russia\u27s crackdown in particular

Topological px+ipyp_{x}+ip_{y} Superfluid Phase of a Dipolar Fermi Gas in a 2D Optical Lattice

In a dipolar Fermi gas, the anisotropic interaction between electric dipoles can be turned into an effectively attractive interaction in the presence of a rotating electric field. We show that the topological $p_{x}+ip_{y}$ superfluid phase can be realized in a single-component dipolar Fermi gas trapped in a 2D square optical lattice with this attractive interaction at low temperatures. The $p_{x}+ip_{y}$ superfluid state has potential applications for topological quantum computing. We obtain the phase diagram of this system at zero temperature. In the weak-coupling limit, the p-wave superfluid phase is stable for all filling factors. As the interaction strength increases, it is stable close to filling factors $n=0$ or $n=1$, and phase separation takes place in between. When the interaction strength is above a threshold, the system is phase separated for any $0<n<1$. The transition temperature of the $p_{x}+ip_{y}$ superfluid state is estimated and the implication for experiments is discussed.Comment: 10 pages, 4 figure

Accurate Extraction of Noise Source Impedance of an SMPS Under Operating Conditions

An accurate measurement method to extract the common mode (CM) and the differential mode (DM) noise source impedances of a switched mode power supply (SMPS) under its operating condition is developed and validated. With a proper pre-measurement calibration process, the proposed method allows extraction of both the CM and the DM noise source impedances with very good accuracy. These noise source impedances come in handy to design an electromagnetic interference (EMI) filter for a SMPS systematically with minimum hassl

QCD evolution of naive-time-reversal-odd fragmentation functions

We study QCD evolution equations of the first transverse-momentum-moment of the naive-time-reversal-odd fragmentation functions - the Collins function and the polarizing fragmentation function. We find for the Collins function case that the evolution kernel has a diagonal piece same as that for the transversity fragmentation function, while for the polarizing fragmentation function case this piece is the same as that for the unpolarized fragmentation function. Our results might have important implications in the current global analysis of spin asymmetries.Comment: 8 pages,4 figure

Diagrammatic calculation of thermodynamical quantities in nuclear matter

In medium T-matrix calculations for symmetric nuclear matter at zero and finite temperatures are presented. The internal energy is calculated from the Galitskii-Koltun's sum rule and from the summation of the diagrams for the interaction energy. The pressure at finite temperature is obtained from the generating functional form of the thermodynamic potential. The entropy at high temperature is estimated and compared to expressions corresponding to a quasiparticle gas.Comment: 9 pages, 5 figure

Self-Interacting Dark Matter Subhalos in the Milky Way's Tides

We study evolution of self-interacting dark matter (SIDM) subhalos in the Milky Way (MW) tidal field. The interaction between the subhalos and the MW's tides lead to more diverse dark matter distribution in the inner region, compared to their cold dark matter counterparts. We test this scenario with two MW satellite galaxies, Draco and Fornax, opposite extremes in the inner dark matter content, and find that they can be accommodated within the SIDM model proposed to explain the diverse rotation curves of spiral galaxies in the field.Comment: 6 pages, 3 figures.
