Recent Results From CHORUS Charm Analysis

The CHORUS experiment was designed to search for $\nu_{\mu}\to \nu_{\tau}$ oscillation by detecting the decay topology of the $\tau$ in charged current (CC) $\nu_{\tau}$ events. The detector was exposed to the Wide Band Neutrino Beam of the CERN SPS during the years 1994-1997. About $10^{6} \nu_{\mu}$ CC events were collected in the nuclear emulsion target. Up to now, about 170,000 $\nu_{\mu}$ events have been located and analysed. The speed of the automated emulsion scanning systems increases each year. With the present performance of these systems, it has become possible to perform large volume scanning. All tracks belonging to an interaction vertex can be recognized and measured precisely. This technique is not only applied to the search for neutrino oscillation but can also be used for the recognition of events where charmed particles are produced. Results obtained from the analysis of a sub-sample of the data on the production rate in $\nu_\mu$ CC interactions of neutral charmed mesons ($D^0$) and charmed baryons ($\Lambda_c$) are presented. In addition a new measurement of the branching ratio for the decays of charmed hadrons into muons is given. Also measurements of topological branching ratios of $D^0$ and $\Lambda_c$ are presented. Finally, a search for associated charm production is discussed.Comment: 6 pages, 1 figure, to appear in the proceedings of the Conference: XXXVIII Rencontres de Moriond: Electroweak Interactions and Unified Theories Les Arcs, France, March 15-22, 200

Novel Feedback Calculation Technique for Improved Transmit Scheme

Extended balanced space-time block coding (EBSTBC) is able to achieve large coding gain and guarantee full diversity for any number of transmit antennas. Performance of the EBSTBC has been improved with improved transmit scheme (ITS) which is combination of the EBSTBC with transmit antenna selection. Performance of the ITS with a limited number of feedback bits approaches to performance of ideal beamforming which requires ideal channel state information at the transmitter. However, the calculation of feedback information at the receiver employs exhaustive searching scheme which is very complex and energy inefficient process. In this work, a low complexity and energy efficient feedback information scheme for the ITS receiver is proposed. Theoretical and simulation results show that the calculation complexity of feedback information is decreased more than 87% and the proposed scheme yields the same bit error rate performance with the ITS. Moreover, the proposed scheme requires very low addition memory with respect to alternative schemes

Assortative mating and Turkish marriage market

The degree of assortative mating shows the degree of similarity within couples. Many papers try to calculate earnings correlations between husbands and wives. This paper tries to calculate the earnings correlations for Turkey and consider the effect of the sample selection. Our results show that there is a weak positive assortative mating in Turkey, and the bias from the selection is small. In addition, we look at the assortative mating coefficients in different regions in Turkey. Akdeniz region has the biggest correlation coefficient. Karadeniz has the lowest coefficient which is almost zero.assortative mating, marriage, earnings

On the Financial Repression in Japan During the High Growth Period (1953-73)

Japanese financial policies during the so called High Growth Period (HGP-roughly 1953-1973) stand at sharp contrast with the presumptions of the financial liberalization literature. Against the Japanese example, McKinnon (1991) and Horiuchi (1984) have argued, based on relatively high interest rates in Japan during this period compared to developed economies, that the Japanese financial market was not repressed. In this paper, Japanese financial policies during the HGP are examined to show the heavy and distortionary but purposeful government intervention in the financial markets. Moreover evidence is provided against those of McKinnon and Horiuchi to show that major interest rates have been repressed during the HGP. Finally, the reasons that forced the Japanese government to implement financial liberalization after 1973 are discussed. These reasons do not include considerations related to growth and the growth performance have declined after 1973.Japanese financial policies

Marriage Premium in Turkey

This paper contributes to the literature in three ways. Our first contribution is calculating the marriage premium for Turkey. Our results suggest that married men earn 27 percent more than single men and married women earn 4 percent less than single women. Our second contribution is calculating the marriage premium for Turkey’s regions. For men, the wage difference is the smallest, 0.43, in Istanbul. The difference is highest in Akdeniz region. For women, the wage difference is smallest, -0.04, in Ege and the highest, 0.62, in Dogu Anadolu. Finally, we estimated the relationship between age and the marriage premium. We found that for men, at younger ages the difference is high. For women, in most of ages single women earn more than married women.marriage, earnings, marriage premium
