Creators: name: Maya-Drysdale, David
name: Magni Johannsen, Rasmus
Publisher: name: Zenodo
Year: 2021

description: This report presents the modelling platform for developing energy-efficient scenarios for the countries of the European Union and the United Kingdom (EU27+UK), applying the Energy Efficiency First Principle. The platform consists of a data component and an energy-system analysis component – this report describes both components. Energy-efficient scenarios for the energy system of each country include all the energy sectors including transport, industry and buildings. The main aim of the following energy system modelling and energy system analysis is to balance energy efficiency and renewable energy integration, enabled by the modelling platform described in this report. The energy system scenario results will feed into a Handbook for science-based interaction with policy objectives aimed at achieving the Energy Efficiency First Principle.

Information Aggregation and Strategic Trading in Speculative Markets
Creators: name: Dutta, Prajit Kumar
Publisher: name: Columbia University
Year: 1992
Subjects: Economics

description: This paper examines the process by which private information is impounded in security prices in a market where some traders are consistently better informed about short-run asset values. We analyze equilibria where traders can adopt general non-cooperative strategies, and characterize the 'best' attainable equilibrium. Trading strategies in this equilibrium are nonlinear functions of information signals and exhibit history dependence. In contrast to previous papers, competition among informed traders need not lead to rapid revelation of private information. Although the volatility of fundamental prices is constant, transaction prices may exhibit time-varying volatility. Finally, in contrast to linear models, the degree to which prices impound private information depends on the signal itself.

description: We measure the statistical polarization of quadrupolar nuclear spins in a sub-micrometer (0.6 um^3) particle of GaAs using magnetic resonance force microscopy. The crystalline sample is cut out of a GaAs wafer and attached to a micro-mechanical cantilever force sensor using a focused ion beam technique. Nuclear magnetic resonance is demonstrated on ensembles containing less than 5 x 10^8 nuclear spins and occupying a volume of around (300 nm)^3 in GaAs with reduced volumes possible in future experiments. We discuss how the further reduction of this detection volume will bring the spin ensemble into a regime where random spin fluctuations, rather than Boltzmann polarization, dominate its dynamics. The detection of statistical polarization in GaAs therefore represents an important first step toward 3D magnetic resonance imaging of III-V materials on the nanometer-scale.

title: Design and Implementation of a High-Contrast, Millijoule-Level Ultrafast Optical Parametric Amplifier for High-Intensity Lasers
Creators: name: Zobus, Yannik
Publisher: name: UNSPECIFIED
Year: 2023

description: The objective of this work was the development of a laser module to improve the temporal contrast of high-intensity laser systems and its implementation at the high-power laser PHELIX at the GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt. By improving the temporal contrast, experiments with laser-plasma interaction under extreme peak intensities should be made possible without disturbing or destroying the target before the arrival of the main pulse. In the frame of this work, I have therefore developed an ultrafast optical parametric amplifier (uOPA), which enables high-temporal-contrast amplification of short laser pulses up to the millijoule range and can thus replace subsequent contrast-degrading amplifier systems. In addition to reducing amplified spontaneous emission, the occurrence of pre-pulses can also be prevented. I have additionally developed a dedicated pump module for this amplifier, which can be used in a wide spectral range around the central wavelength of 1 μm and thereby can be implemented on various laser systems as a pump laser for uOPA systems. Thus, in addition to the high-contrast amplifier for the Nd:glass laser system PHELIX, I have built a second uOPA module for use in the diode-pumped Yb:CaF2 laser system PENELOPE. I implemented the module on the high-power PHELIX laser as part of this work, which successfully replaced an amplifier, which generated intense pre-pulses, in the amplification chain. This allowed me to lower the pre-pulse contrast at PHELIX by nearly three orders of magnitude to a contrast level of 6.2·10⁻¹¹, keeping the pre-pulse intensity, even for the highest possible intensity at PHELIX, below 100 GW/cm².
Real Exchange Rate and U.S. Manufacturing Profits: Theoretical Framework with Some Empirical Support
Creators: name: Clarida, Richard H.
Publisher: name: Columbia University
Year: 1992
Subjects: Economics

description: This paper investigates the relationship between manufacturing profits and the real exchange rate. Using Marston's (1990) model of pricing-to-market, we identify two channels, a valuation channel and volume channel, through which changes in the real exchange rate can shift the profits of a price-setting exporter. Employing the econometric approach developed Johansen (1990; 1991), we estimate a dynamic vector error correction model on quarterly data for real US manufacturing profits and five variables that theory suggests should be useful in accounting for the behavior of real profits in an open economy: domestically sold outpput, the real exchange rate, real unit costs, the relative price of domestically sold output, and real foreign income. Finding evidence of cointegration, we estimate via maximum likelihood the single cointegrating relationship that is defined by the conditional probability distribution of real manufacturing profits implied by the VECM. We test, and confirm, that both real profits and the real exchange rate are elements of this cointegrating vector, and interpret this cointegrating relationship as a long-run open economy profits equation. Our estimates imply that, holding constant domestic sales, real unit costs, the relative price of domestic output, and real foreign income, the long-run elasticity of real profits with respect to the real exchange rate exceeds 0.80.
Retail banking: Sanwa Bank: Sustaining long-term advantage through information technology

description: This retail banking case together with other cases3 support an initial research hypothesis that leading software users in the US and Japan are very sophisticated in the ways they have integrated software into their management strategies and use it to institutionalize organizational strengths and capture tacit knowledge on an iterative basis. In Japan this strategy has involved heavy reliance on customized and semi-customized software (Rapp 1995) but is changing towards a more selective use of package software managed via customized systems. In turn, US firms, such as Merck, who have often relied more on packaged software, are doing more customization, especially for systems needed to integrate software packages into something more closely linked with its business strategies, markets, and organizational structure. Thus, coming from different directions, there appears to be some convergence in approach by these leading software users. The cases thus confirm what some other analysts have hypothesized; a coherent business strategy is a necessary condition for a successful information technology strategy (Wold and Shriver 1993). These strategic links for Sanwa are presented in the following case.
Trade and growth: Import led or export led? Evidence from Japan and Korea

description: It is commonly argued that Japanese trade protection has enabled the nurturing and development internationally competitive firms. The results in our paper suggest that when it comes to TFP growth, this view of Japan is seriously erroneous. We find that lower tariffs and higher import. volumes would have been particularly beneficial for Japan during the period 1964 to 1973. Our results also lead us to question whether Japanese exports were a particularly important source of productivity growth. Our findings on Japan suggest that the salutary impact of imports stems more from their contribution to competition than to intermediate inputs. Instead, this paper suggests that Japan's performance was perhaps even more of a miracle than we thought, since it occurred despite the maintenance of protectionist barriers. Furthermore our results indicate a reason for why imports are important. Greater imports of competing products spur innovation. Our results suggest that competitive pressures and potentially learning from foreign rivals are important conduits for growth. These channels are even more important as industries converge with the market leader. This suggests that further liberalization by Japan and other East Asian countries may result in future dynamic gains. While our analysis has principally focused on Japan, we have also provided corroborating evidence suggesting that our conclusions apply more broadly. Imports into the US seem to be an important factor in promoting productivity growth. The evidence for Korea suggests similar impacts from imports and tariffs and no evidence that exports promoted productivity. Our results thus call the views of both the World Bank and the revisionists into question and provide support for those who advocate more liberal trade policies.
Worker discontent, voice, and EI programs in Japan: Evidence from the Japanese worker representation and participation survey

description: Using a unique new survey, the Japanese Worker Representation and Participation Survey (JWRPS), this paper documents that there is currently an alarming degree of worker discontent in Japan. Specifically, we find that: (i) nearly one in two Japanese workers usually do not look forward to going to work; (ii) almost one third of Japanese workers are dissatisfied with their current jobs and do not at all feel loyal to their employers or feel loyal only a little; (iii) nearly one in five Japanese workers either do not at all trust information provided by their firm or trust such information only a little; and (iv) fully 40 percent of Japanese workers rate labor management relations as only fair or poor. Estimating probit models, we find systematic evidence that such worker discontent is significantly related to the lack of strong employee voice on decisions affecting workplaces, and that the lack of or weakened use of Japan's once celebrated EI programs (such as Shopfloor Committees, Small Group Activities, and Joint Labor-Management Committees) is in part responsible for weak voice and hence an alarming degree of worker discontent. An important policy implication of our findings is that weakening Japan's participatory employment system (as the popular rhetoric at times suggests) may result in exacerbating the already alarming degree of worker discontent in Japan, and ultimately weakening the competitiveness of the Japanese economy.
Large-scale Bayesian computation using Stochastic Gradient Markov Chain
      Monte Carlo
Creators: name: Baker, Jack
Publisher: name: Lancaster University
Year: 2019

description: Markov chain Monte Carlo (MCMC), one of the most popular methods for
      inference on Bayesian models, scales poorly with dataset size. This is
      because it requires one or more calculations over the full dataset at each
      iteration. Stochastic gradient Markov chain Monte Carlo (SGMCMC) has
      become a popular MCMC method that aims to be more scalable at large
      datasets. It only requires a subset of the full data at each iteration.
      This thesis builds upon the SGMCMC literature by providing contributions
      that improve the efficiency of SGMCMC; providing software that improves
      its ease-of-use; and removes large biases in the method for an important
      class of model.

      While SGMCMC has improved per-iteration computational cost over
      traditional MCMC, there have been empirical results suggesting that its
      overall computational cost (i.e. the cost for the algorithm to reach an
      arbitrary level of accuracy) is still $O(N)$, where $N$ is the dataset
      size. In light of this, we show how control variates can be used to
      develop an SGMCMC algorithm of $O(1)$, subject to two one-off
      preprocessing steps which each require a single pass through the dataset.

      While SGMCMC has gained significant popularity in the machine learning
      community, uptake among the statistics community has been slower. We
      suggest this may be due to lack of software, so as part of the
      contributions in this thesis we provide an R software package that
      automates much of the procedures required to build SGMCMC algorithms.
      Finally, we show that current algorithms for sampling from the simplex
      space using SGMCMC have inherent biases, especially when some of the
      parameter components are close to zero. To get around this, we develop an
      algorithm that is provably asymptotically unbiased. We empirically
      demonstrate its performance on a latent Dirichlet allocation model and a
      Dirichlet process model.

description: The population activity of random networks of excitatory and inhibitory leaky integrate-and-fire (LIF) neurons has been studied extensively. In particular, a state of asynchronous activity with low firing rates and low pairwise correlations emerges in sparsely connected networks. We apply linear response theory to evaluate the influence of detailed network structure on neuron dynamics. It turns out that pairwise correlations induced by direct and indirect network connections can be related to the matrix of direct linear interactions. Furthermore, we study the influence of characteristics of the neuron model. Interpreting the reset as self-inhibition we examine its influence, via the spectrum of single neuron activity, on network autocorrelation functions and the overall correlation level. The neuron model also affects the form of interaction kernels and consequently the time-dependent correlation functions. We finally find that a linear instability of networks with Erdős-Rényi topology coincides with a global transition to a highly correlated network state. Our work shows that recurrent interactions have a profound impact on spike train statistics and provides tools to study effects of specific network topologies.

description: Previous climate-crime studies are primarily grounded on conventional statistical methods, leaving the possible non-linear nature of the climate-crime association insufficiently explored. In the present study, we employed both multiple linear regression and wavelet analyses and compared their results to detect and verify the possible non-linear effect of temperature and precipitation change on crimes in an urban setting. Nine types of crimes in Hampton Roads, Virginia, USA during 1973–2009 were analyzed. Results show that temperature was the significant determinant of crimes in both of the analyses. Wavelet coherency analysis demonstrates that temperature and crimes exhibited common modes of oscillation in ∼1-year periodicity, which may be attributable to the seasonality of crimes. We further found that the seasonality of crimes was determined by the seasonal change of temperature rather than that of precipitation. In parallel, precipitation and crimes exhibited common modes of oscillation in ∼11-year periodicity, revealing their association at the decadal scale. Our results indicate that temperature and precipitation determine crime rates at different time scales. Nonetheless, when the crests of the temperature-crime and the precipitation-crime cycles overlap, crime rates may be reinforced to their greatest extent. The above findings may help inform and prepare necessary security arrangements in advance. Further research could be conducted to see whether the above findings could be applied to the metropolitan regions with the similar geographic settings of Hampton Roads, such as the Jing-Jin-Ji (Beijing-Tianjin-Hebei) region in northern China.

description: SDSS J120136.02+300305.5 was detected in an XMM-Newton slew from June 2010 with a flux 56 times higher than an upper limit from ROSAT, corresponding to Lx~3x10^44 ergs/s. It has the optical spectrum of a quiescent galaxy (z=0.146). Overall the X-ray flux has evolved consistently with the canonical t^-5/3 model, expected for returning stellar debris from a tidal disruption event, fading by a factor ~300 over 300 days. In detail the source is very variable and became invisible to Swift between 27 and 48 days after discovery, perhaps due to self-absorption. The X-ray spectrum is soft but is not the expected tail of optically thick thermal emission. It may be fit with a Bremsstrahlung or double-power-law model and is seen to soften with time and declining flux. Optical spectra taken 12 days and 11 months after discovery indicate a deficit of material in the broad line and coronal line regions of this galaxy, while a deep radio non-detection implies that a jet was not launched during this event.

description: We find that the CAPM beta has little ability to explain the cross section of average returns on Japanese stocks when the TOPIX return is used as the proxy for the return on the aggregate wealth portfolio. The relation between average return and beta is flat, with an R-Square of less than 3%. The empirical performance of the CAPM improves substantially if a measure of the return on human capital is also included when measuring the return on the aggregate wealth portfolio -- the R-Square rises to 75%. There is little evidence against the CAPM specification with this modification. It performs almost as well as the linear factor model which, following Fama and French, uses the TOPIX return and the payoffs on portfolios that capture the size and book to price effects found in the data as the three factors.
Three Essays in Finance
Creators: name: Zhang, Feng
Publisher: name: University of British Columbia
Year: 2011

description: This dissertation contains three studies. Chapter 2 investigates interactions between antitakeover provisions and managerial ownership, two corporate governance mechanisms. Antitakeover provisions weaken the incentive effect of managerial ownership and magnify its entrenchment effect, and thus will decrease the effect of managerial ownership on firm value. I show that the value effect of managerial ownership crucially depends on the strength of antitakeover provisions. For firms with weak antitakeover provisions, managerial ownership enhances firm value, unless managers have very high ownership. For firms with strong antitakeover provisions, however, increasing managerial ownership always destroys firm value. Also, managerial ownership significantly decreases with the strength of antitakeover provisions. These findings support the hypotheses that antitakeover provisions decrease the value effect of managerial ownership and affect managers' compensation contract. Chapter 3 proposes a model to investigate the role of information precision in IPO pricing. The model shows that more precise information will exert more influence on the offer price. In strong support of the model, I find that the proportion of the industry return during the waiting period that is incorporated into the offer price increases with a proxy for precision of the industry return as a measure of the change in the IPO firm's value during the waiting period. This study enhances our understanding of the partial adjustment phenomenon: noisy information will be partially incorporated into the offer price. Chapter 4 shows that young male CEOs appear to be combative: they are four percent more likely to be acquisitive and, having initiated an acquisition, they are over 20 percent more likely to withdraw an offer. Furthermore, a young target male CEO is two percent more likely to force a bidder to resort to a tender offer. We argue that this combative nature is a result of testosterone levels that are higher in young males. Testosterone is a hormone associated with male dominance seeking. The acts of attempting or resisting an acquisition can be viewed as striving to achieve dominance. We argue that the evidence reported in this paper is consistent with the presence of a significant hormone effect in M&As.

We determine the two point galaxy correlation function at linear order in perturbation theory. Redshift space distortions are taken into account for arbitrary angular and redshift separations. We discuss the shape of the longitudinal and the transversal correlation functions which are very different from each other and from their real space counterpart. We then go on and suggest how to measure both, the Hubble parameter, $H(z)$, and the angular diameter distance, $D_A(z)$, separately from these correlation functions and perform an Alcock-Paczynski test.

The correctness of the results of the numerical evaluation of new eighth order QED corrections to the electron anomaly are supported by the demonstration of their consistency with the new analytical expressions for the QED contributions to $a_e$ from the diagrams with fourth-order light-by-light scattering muon and tau-lepton loops. The consistency of the similar results are demonstrated in the case of eighth order massive dependent contribution to the muon anomalous magnetic moment.

description: The tropical mountainous area of the southeastern Tibetan Plateau (TP) is a hotspot of ecological environment research because of its rich biodiversity. However, limited knowledge regarding modern pollen rain within this area has impeded further investigation of eco-environmental evolution using the pollen record. We collected 62 modern pollen samples from lowland tropics to the subalpine region (740–3550 m a.s.l.) in Medog County, located in the southeastern TP, and performed pollen analysis. Cluster analysis, redundancy analysis, variance partitioning analysis, and boosted regression trees were employed to investigate the relationship between pollen and vegetation/climate. Additionally, Hill numbers (N0, N1, N2) and specificity–occupancy plots were utilized to explore plant diversity. The results indicate that modern pollen rain in Medog reflects well the current characteristics of the vegetation, encompassing both primary and secondary features. Pollen of Cyclobalanopsis, Tsuga and Abies, which are dominant components of the primary vegetation above 2100 m a.s.l., can serve as indicator species for paleovegetation reconstructions. Mean annual precipitation is the most important climatic determinant affecting pollen distribution. Pollen indices reveal that the plant diversity in this study area has a bimodal pattern of ‘relatively high–low–highest–low’ with increasing altitude. The plant diversity above 2100 m a.s.l. is mainly decided by primary vegetation, whereas below 2100 m a.s.l. it can be explained by the intermediate disturbance hypothesis. Furthermore, it is advisable to exercise caution when dealing with arboreal pollen evenness in open mountainous environments due to the increased potential pollen source area caused by valley wind.

description:
The Democratic Republic of the Congo (DRC) harbors 11% of global malaria cases, yet little is known about the spatial and genetic structure of the parasite population in that country. We sequence 2537 Plasmodium falciparum infections, including a nationally representative population sample from DRC and samples from surrounding countries, using molecular inversion probes - a high-throughput genotyping tool. We identify an east-west divide in haplotypes known to confer resistance to chloroquine and sulfadoxine-pyrimethamine. Furthermore, we identify highly related parasites over large geographic distances, indicative of gene flow and migration. Our results are consistent with a background of isolation by distance combined with the effects of selection for antimalarial drug resistance. This study provides a high-resolution view of parasite genetic structure across a large country in Africa and provides a baseline to study how implementation programs may impact parasite populations.

We use ACS images from the Hubble Space Telescope in F435W and F814W bands. The galaxies in the sample represent different interaction phases and cover a wide luminosity range (11.46 \leq log (L_IR (Lsun)) \leq 12.54). With a median size of 32 pc, most of the nearly 3000 knots detected consists of complexes of star clusters. Some of the knots (~15%) are so blue that their colors indicate a young (i.e., < 30 Myr) and almost extinction-free population. There is a clear correlation of the mass of these blue knots with their radius, M \propto R^{1.91\pm0.14}, similar to that found in complexes of clusters in M51 and in Giant Molecular Clouds. This suggests that the star formation within the knots is proportional to the gas density at any given radius. The star formation of all the knots is characterized by luminosity functions (LFs) of the knots with slopes close to 2. Though, we see a marginally significant indication that the LF evolves with the interaction process, becoming steeper from early to advanced merger phases. Due to size-of-sample effects we are probably sampling knots in ULIRGs intrinsically more luminous (x4) than in less luminous systems. They also have sizes and are likely to have masses characteristic of clumps in galaxies at z \gtrsim 1. Knots in post-mergers are on average larger (x 1.3-2), more luminous (2 mag) in the I-band, and 0.5 mag redder than those in systems in earlier phases. Two scenarios are briefly discussed: (1) the likely presence of relatively high extinction in the most advanced mergers; (2) the dissolution of the less massive clusters and/or their coalescence into more massive, evolved superclusters.

Correlation functions of three heavy operators - the AdS contribution

description: We consider operators in N=4 SYM theory which are dual, at strong coupling, to classical strings rotating in S^5. Three point correlation functions of such operators factorize into a universal contribution coming from the AdS part of the string sigma model and a state-dependent S^5 contribution. Consequently a similar factorization arises for the OPE coefficients. In this paper we evaluate the AdS universal factor of the OPE coefficients which is explicitly expressed just in terms of the anomalous dimensions of the three operators.

description: Oil fluid property gradients at regional, field and reservoir scales are ubiquitous in heavy oil and bitumen deposits in the Alberta Basin and develop via biodegradation at oilwater transition zones, oil charge to the reservoir top and advective-diffusive mixing controlled by oil composition and reservoir geometry. Orders of magnitude variations in bitumen viscosity with reservoir depth adversely impact total recovery from SAGD and cold production operations which require uniform fluid mobility. Regional decreasing biodegradation trends to the west in northern Alberta result from reservoir pasteurization near 80°C, west of Peace River oil sands (PROS), and increasingly cooler time-integrated reservoir temperatures to the east, in the PROS and Athabasca oil sands. Simple charge-degrade box models of these deposits show that early oil charge around 100 to 90 Ma and limitation of the biodegradation rate due to reservoir temperature, water and nutrient availability and oil composition are required to predict observed westerly decreasing trends in oil biodegradation. Reservoir-scale concentration gradients in PROS reservoirs are related to reservoir geometry, local shale barriers and biodegradation rates controlled by water saturation, biodegradation susceptibility and diffusivity of hydrocarbon substrates. 1D compositional diffusion models match observed oil component concentration gradients by inclusion of geological barriers, variable thickness oil-water biodegradation zones. Numerical models of carbon isotope systematics identify the dominant reaction pathway of subsurface hydrocarbon biodegradation as methanogenic alkane degradation using carbon dioxide reduction, which produces isotopically light methane and heavy CO2 in solution gas. Basin models show that regional biodegradation significantly impacts oil quality, and fill, spill and leakage histories due to generation and migration of biogenic gas. Full physics models of hydrocarbon biodegradation predict replacement of thermogenic gas with biogenic gas, dissolution of biogenic CO2 into the water leg and development of gas caps over geological time. None of these models adequately predict fluid properties required for exploration and production operations, thus multivariate statistics models of hydrocarbon composition were developed to predict PROS dead oil viscosity. Oil viscosity assessed from core samples can increase dramatically during core storage and oil recovery and a core storage time correction algorithm was developed to minimize "noise" in calibration data sets.

description: In this paper, a stochastic asymptotic stabilization method is proposed for deterministic input-affine control systems, which are randomized by including Gaussian white noises in control inputs. The sufficient condition is derived for the diffucion coefficients so that there exist stochastic control Lyapunov functions for the systems. To illustrate the usefulness of the sufficient condition, the authors propose the stochastic continuous feedback law, which makes the origin of the Brockett integrator become globally asymptotically stable in probability.

I would like to offer a few observations on how the project to establish a common European currency is progressing and then to trace through some of the implications of that currency, the Euro, for the dollar, the yen, and the financial markets more generally. But before turning to that important subject, I want to make some comments on the recent turmoil in the world’s financial markets."
Recruitment of synaptic vesicles to developing synapses
Creators: name: Sun, Yu
Publisher: name: University of British Columbia
Year: 2011

description: Synapse formation begins with the recognition of appropriate targets and formation of incipient contacts, and culminates with the recruitment of pre- and postsynaptic proteins to points of cell-cell contact. It is still unclear how cell-cell contact translates into the recruitment of synaptic proteins. Previous studies have shown that the cadherin/β-catenin cell adhesion complex plays an important role in localizing synaptic vesicles to developing synapses. This dissertation discusses work elucidating the transduction pathway that is activated following cell-cell contact, leading to the recruitment and retention of synaptic vesicles to presynaptic compartments. Using rat and mouse primary hippocampal cultures as a model system, we have demonstrated that β-catenin mediates the localization of synaptic vesicles to synapses through its recruitment of the PDZ scaffold protein, scribble, and it’s subsequent recruitment of the Rac/Cdc42 guanine nucleotide exchange factor, β-pix. We further demonstrate that β-pix enhances actin polymerization at these discrete sites, which is important for the “trapping” of synaptic vesicles as they translocate along the axon. We have demonstrated that cadherin, β-catenin, scribble, and β-pix form a complex at developing synapses using immunohistochemistry coupled with immunoprecipitation assays using synaptosomal fractions. Knockdown of β-catenin, scribble or β-pix using RNA interference (RNAi) disrupts the appropriate localization of synaptic vesicles at synapses. We have ordered this pathway and have shown that β-catenin is important for the recruitment and clustering of scribble to synapses, but that scribble knockdown does not affect β-catenin localization. We have also demonstrated that scribble knockdown disrupts the clustering of β-pix at synaptic sites. This complex has shown to control vesicle localization through β-pix-mediated enhancement of actin polymerization at these discrete sites. Indeed, β-pix knockdown results in decreased actin polymerization at synapses. Importantly, restoring actin polymerization at synapses through cortactin overexpression rescues the mislocalization of synaptic vesicles. This work provides novel insights into the molecular and cellular mechanisms underlying the development presynaptic compartments.

description: Most of the discussions and analyses of Japanese banks focus on the lingering effects of the collapse of the bubble economy during the 1990's. There is limited foreign coverage of the forward-looking projects of Japanese banks. This paper attempts to fill this void by providing an overview of the recent development of electronic money in Japan. While these projects are not unusually remarkable, the experiences of Japanese banks during the 1990's will provide them with ample growth opportunities in the next century.

description: It is arguable whether history is made by great men and women or vice versa, but undoubtably social connections shape history. Analysing Wikipedia, a global collective memory place, we aim to understand how social links are recorded across cultures. Starting with the set of biographies in the English Wikipedia we focus on the networks of links between these biographical articles on the 15 largest language Wikipedias. We detect the most central characters in these networks and point out culture-related peculiarities. Furthermore, we reveal remarkable similarities between distinct groups of language Wikipedias and highlight the shared knowledge about connections between persons across cultures.
