Performance of the CMS Cathode Strip Chambers with Cosmic Rays

The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. Measured noise levels are low, with the number of noisy channels well below 1%. Coordinate resolution was measured for all types of chambers, and fall in the range 47 microns to 243 microns. The efficiencies for local charged track triggers, for hit and for segments reconstruction were measured, and are above 99%. The timing resolution per layer is approximately 5 ns

Performance and Operation of the CMS Electromagnetic Calorimeter

The operation and general performance of the CMS electromagnetic calorimeter using cosmic-ray muons are described. These muons were recorded after the closure of the CMS detector in late 2008. The calorimeter is made of lead tungstate crystals and the overall status of the 75848 channels corresponding to the barrel and endcap detectors is reported. The stability of crucial operational parameters, such as high voltage, temperature and electronic noise, is summarised and the performance of the light monitoring system is presented

How Interdependent are Eastern European Economies and the Euro Area?

This article investigates the interrelations between the Euro area and five Central and Eastern European economies. Using an open economy framework, we derive theoretical restrictions to be imposed on the cointegration space of a structural vector error correction model. We employ generalized impulse response analysis to assess the effects of shocks in output, interest rates, the exchange rate, and relative prices on both areas. The results show strong international spillovers in output with the magnitude being similarly strong in both areas. Furthermore, we find multiplier effects in Central and Eastern Europe and some evidence for the European Central Bank´s desire toward price stability

Performance of CMS hadron calorimeter timing and synchronization using test beam, cosmic ray, and LHC beam data

This paper discusses the design and performance of the time measurement technique and of the synchronization systems of the CMS hadron calorimeter. Time measurement performance results are presented from test beam data taken in the years 2004 and 2006. For hadronic showers of energy greater than 100 GeV, the timing resolution is measured to be about 1.2 ns. Time synchronization and out-of-time background rejection results are presented from the Cosmic Run At Four Tesla and LHC beam runs taken in the Autumn of 2008. The inter-channel synchronization is measured to be within ±2 ns

Heterogeneous consumption in OLG model with horizontal innovations

The paper develops a general equilibrium endogenous growth model involving heterogeneous consumption by an age-structured population with uncertain but limited life span and balanced life-time budget without bequests. The heterogeneity is introduced via weights which the individuals attribute in their utility function to consumption of different goods depending on the vintage of the good. The goods are produced by monopolistically competitive firms and the variety of available goods/technologies is determined endogenously through R&D investments. A competitive bank sector provides financial resources for investments, secured by agents’ savings and future firms profits. The general equilibrium is characterized by a system of functional equations and is analytically or numerically determined for several particular weight functions. It is shown that the investments by agents alone may be insufficient to sustain growth, while additional investments provided by the bank sector may lead to growth. The resulting imbalance between agents’ assets and the total value of firms can grow unboundedly in the case of homogeneous consumption. The results exhibit the qualitative difference between the dynamics of the model with heterogeneous versus homogeneous consumption. In particular heterogeneous con- sumption (when old goods are discounted) reduces the additional investments by the financial sector so that the values of firms become balanced by the assets of agents in the long run.info:eu-repo/semantics/publishedVersio

Population, Wealth, and Economic Growth in the Asia and Pacific Region

We explore how demographic changes in the Asia and Pacific region are likely to influence economic growth and other features of the regional economy. While many low-income countries in the region will continue to experience a demographic dividend, over time population aging could drag on economic growth, especially in East Asia. A second potential problem from population aging is the strain on public transfer systems the effects of which, although smaller than those in Europe, Japan, or Latin America, will still be large. Countering these problems, however, population aging will lead to substantial capital deepening, an effect of the second demographic dividend. Given current patterns of old-age consumption, production, and transfers, the total demand for pension assets will increase very substantially over the coming decades. Under these circumstances, aging should not depress savings rates. Capital deepening and high standards of living are attainable despite significant population aging

The Impact of 3D Printing on Trade and FDI

This paper analyzes the effects of 3D printing technologies on the volume of trade and on the structure of FDI. A standard model with firm-specific heterogeneity generates three main predictions. First, 3D printers are introduced in areas with high economic activity that also face high transport costs. Second, technological progress related to 3D printing machines leads to a gradual replacement of FDI that relies on traditional production structures with FDI based on 3D printing techniques. At this stage international trade stays unaffected. Finally, at later stages, with 3D printing machines being widely used, further technological progress in 3D printing leads to a gradual replacement of international trade. Empirical evidence indicates that countries subject to higher transport costs and with high levels of economic activity are indeed among the ones that import more 3D printers. Anecdotal evidence also supports the second and third predictions of the model
