Workshop 3 : Changes in neural orchestration and the neural code W 3-1 : Neural synchrony during bimanual motor behaviour and visuotactile integration

Christian Gerloff University Medical Center Hamburg-Eppendorf, Department of Neurology Converging evidence indicates that information can be represented in the brain by the functional coupling of distant brain areas. Here, 3 sets of experiments addressing interregional neural synchrony in humans during integrative sensorimotor behaviour are reviewed. The conclusion of a first study (Andres et al. 1999) was that task-related coherence (TRCoh) reflects changes in interhemispheric communication that are specifically related to bimanual learning and may be relayed through the corpus callosum. Further analyses with partial task-related coherence and directed transfer function as well as with fMRI pointed to a crucial role of the posterior parietal cortex as a region acting as a driver of bimanual motor integration. The conclusion of a second set of experiments (Hummel and Gerloff 2005) was that the amount of long-range synchrony is quantitatively linked with the degree of behavioural success in humans in a visuo-tactile integration paradigm. The ability to generate topographically specific synchrony of high amplitude appeared to be functionally relevant for behavioural success. In this study, the divergence between (unchanged) local activation and (dynamically modulated) TRCoh raised the possibility that magnitude of regional activation is less representative of the efficacy of brain functioning than interregional synchrony. The conclusion of a third set of experiments (Plewnia et al. 2008) was that synchronous bifocal transcranial magnetic stimulation (TMS) is feasible for selective modulation of interregional EEG coherence. In summary, (i) EEG coherence shows specific modulations during tasks requiring large-scale neuronal interaction, (ii) variations of interregional neural synchrony are quantitatively linked to the level of behavioural performance, and (iii) it is possible to modulate interregional synchrony with bifocal TMS, rendering it possible in the future to address the functional causal relationship between connectivity measures and behaviour more directly.
Secure Domain Name System (DNS) Deployment Guide

The Domain Name System (DNS) is a distributed computing system that enables access to Internet resources by user-friendly domain names rather than IP addresses, by translating domain names to IP addresses and back. The DNS infrastructure is made up of computing and communication entities called Name Servers each of which contains information about a small portion of the domain name space. The domain name data provided by DNS is intended to be available to any computer located anywhere in the Internet.This document provides deployment guidelines for securing DNS within an enterprise. Because DNS data is meant to be public, preserving the confidentiality of DNS data. The primary security goals for DNS are data integrity and source authentication, which are needed to ensure the authenticity of domain name information and maintain the integrity of domain name information in transit. This document provides extensive guidance on maintaining data integrity and performing source authentication. DNS components are often subjected to denial-of-service attacks intended to disrupt access to the resources whose domain names are handled by the attacked DNS components. This document presents guidelines for configuring DNS deployments to prevent many denial-of-service attacks that exploit vulnerabilities in various DNS components.
On North Pacific Temperature, Salinity, Sound Velocity and Density Frontsand their Relation to the Wind and Energy Flux Fields

Abstract The main oceanic fronts of the North Pacific are investigated and the principal frontogenetic processesdescribed. Fronts are features of the upper ocean and occur near mass transport and energy flux convergencezones. Frontogenesis in the upper layers of the ocean is strongly dependent upon the configuration of thewind stress field. Temperature and salinity fronts in the upper ocean are not necessarily coincident, nor arethey always accompanied by density fronts. During periods of strong and persistent winds, the upper andlower portions of the front may separate at pycnocline depth by as much as 200 km, suggesting Ekman-typedisplacement of the upper layer. Multiple temperature and salinity fronts, spaced 60-70 km apart andsuggestive oi baroclinic Rossby waves, are observed off northeastern Japan at the confluence ol the Kurosniowith the Oyashio. Not all temperature and salinity fronts are accompanied by strong baroclinic flow and themaximum baroclinic flow often occurs several kilometers distant f.
What's that gene (or protein)? Online resources for exploring functions of genes, transcripts, and proteins

The genomic era has enabled research projects that use approaches including genome-scale screens, microarray analysis, next-generation sequencing, and mass spectrometry–based proteomics to discover genes and proteins involved in biological processes. Such methods generate data sets of gene, transcript, or protein hits that researchers wish to explore to understand their properties and functions and thus their possible roles in biological systems of interest. Recent years have seen a profusion of Internet-based resources to aid this process. This review takes the viewpoint of the curious biologist wishing to explore the properties of protein-coding genes and their products, identified using genome-based technologies. Ten key questions are asked about each hit, addressing functions, phenotypes, expression, evolutionary conservation, disease association, protein structure, interactors, posttranslational modifications, and inhibitors. Answers are provided by presenting the latest publicly available resources, together with methods for hit-specific and data set–wide information retrieval, suited to any genome-based analytical technique and experimental species. The utility of these resources is demonstrated for 20 factors regulating cell proliferation. Results obtained using some of these are discussed in more depth using the p53 tumor suppressor as an example. This flexible and universally applicable approach for characterizing experimental hits helps researchers to maximize the potential of their projects for biological discovery.
Work based assessment

In 1990 psychologist George Miller proposed a framework for assessing clinical competence. At the lowest level of the pyramid is knowledge (knows), followed by competence (knows how), performance (shows how), and action (does). In this framework, Miller distinguished between “action” and the lower levels. “Action” focuses on what occurs in practice rather than what happens in an artificial testing situation. Work based methods of assessment target this highest level of the pyramid and collect information about doctors' performance in their normal practice. Other common methods of assessment, such as multiple choice questions, simulation tests, and objective structured clinical examinations (OSCEs) target the lower levels of the pyramid. Underlying this distinction is the sensible but still unproved assumption that assessments of actual practice are a much better reflection of routine performance than assessments done under test conditions. This article explains what is meant by work based assessment and presents a classification scheme for current methods Fig 1 Miller's pyramid for assessing clinical competence Although the focus of this article is on practising doctors, work based assessment methods apply to medical students and trainees as well. These methods can be classified in many ways, but this article classifies them in two dimensions. The first dimension describes the basis for making judgments about the quality of performance. The second dimension is concerned with how data are collected. Classification for work based assessment methods ### Outcomes In judgments about the outcomes of their patients, the quality of a cardiologist, for example, might be judged by the mortality of his or her patients within 30 days of acute myocardial infarction. Historically, outcomes have been limited to mortality and morbidity, but in recent years the number of clinical end points has been expanded. Patients' satisfaction, functional status, cost effectiveness, and intermediate outcomes—for example, HbA1c and lipid concentrations for diabetic …
Nutrient Physiology , Metabolism , and Nutrient-Nutrient Interactions Diacylglycerol Oil Does Not Affect Portal Vein Transport of Nonesterified Fatty Acids but Decreases the Postprandial Plasma Lipid Response in Catheterized Pigs 1

Studies have shown several beneficial effects of dietary diacylglycerol oil (DAG oil), but the mechanism behind these effects is still not clear. One hypothesis is that an increase in portal vein transport of nonesterified fatty acids (NEFA) with subsequent oxidation in the liver might be responsible for the positive effects. We examined the portal vein transport of NEFA and other lipid related variables, in response to DAG and triacylglycerol (TAG) bolus feeding and a bolus of standard pig feed in 4 portal vein and mesenteric artery catheterized pigs. Also, the effect of the boluses on postprandial lipid variables was examined. Portal vein transport of NEFA did not differ when pigs were administered the 2 oil bolus diets, consistent with the similar portal plasma concentrations of oleic and linolenic acids during h 1 after feeding. Glycerol, on the contrary, was transported by the portal vein to a much higher degree after intake of DAG oil (P , 0.001; 20, 40, and 60 min). The postprandial arterial TAG response at 5 and 6 h postprandially was significantly lower after the DAG bolus intake. Analysis of D AUC for the 6-h postprandial period of selected and total fatty acids showed a lower concentration of vaccenic acid (P 1⁄4 0.002) after the DAG bolus diet. In conclusion, DAG bolus feeding did not increase the portal transport of NEFA, but it did increase the portal transport of glycerol and lower the postprandial lipid concentration in arterial plasma.

QUANTIFICATION DES EBOULEMENTS/ECROULEMENTS DANS LES PAROIS A PERMAFROST DE HAUTE MONTAGNE: QUATRE ANNEES DE RELEVES LASER TERRESTRES DANS LE MASSIF DU MONT-BLANC

In the last decade, major rockfalls have occurred in high mountains around the world. If the hypothesis of a relationship between rockfalls and global warming through permafrost degradation gains force today, frequency and intensity of rockfalls are still poorly known because of a lack of systematic observations. Here we present the applied methodology for geomorphological monitoring of rockwalls in the Mont-Blanc massif. It consists in acquiring high resolution 3D models by laserscanning once or twice a year, and in comparing these diachronic models in order to measure the detached rock volumes between two surveys. This is carried out using an Optech ILRIS-3D terrestrial laserscanner, ranging up to 800 m in the best conditions of reflectivity of the rock surfaces. Points are obtained at a frequency of 2000 points per second, and the accuracy of measurement at a distance of 100 m is about 7-8 mm. We also present and discuss the main results of the first four years of measurement for the different studied rockwalls.
The Economics of China: Successes and Challenges

This paper is the first chapter in the Oxford Companion to the Economics of China (Oxford University Press, forthcoming). Rather than trying to summarize other contributors' views, we provide our own perspectives on the Economics of China--the past experience and the future prospects. Our reading of China's economic development over the past 35 years raises two major sets of issues, one of which is inward looking, and the other of which is outward looking. While Chinese aggregate development is impressive, it has raised the question of whether the growth is sustainable, and has led to a set of distributional issues and well-being concerns. We argue that these internal issues combine with those raised by China's rapid integration and ever growing presence in the international arena, to jointly frame the challenges faced by China in the next 35 years, as it approaches the 100th anniversary of the People's Republic in 2049.
The Economics of Latin American Art: Creativity Patterns and Rates of Return

In this paper I use a large data set to analyze two aspects of the Latin American arts: (1) the nature of artistic creative process, and (2) Latin American art as an investment. I use data on auctions to understand the relation between artists' age and the value of their work. The analysis on creativity suggests that Latin American artists have followed very different patterns from that followed by U.S. artists. There is strong evidence suggesting that American artists born after 1920 did their best work at an earlier age than their older colleagues; exactly the opposite is true for the case of Latin America. Indeed, the results reported in this paper suggest that Latin American artists born after 1920 did their best work at a significantly older age than their colleagues from earlier cohorts. The analysis of art as an investment is based on the estimation of hedonic price indexes, and indicates that Latin American art has had a relatively high rate of return indeed much higher than that of other type of paintings. The results also indicate that returns on Latin American art have a very low degree of correlation that is, a very low beta relative to an international portfolio comprised of equities. This means that adding Latin American art will lower the overall risk of an international portfolio.
Footprints in the sand: appraising the archaeology of the Willandra Lakes, western New South Wales, Australia

Here is a paper of pivotal importance to all prehistorians attempting to reconstruct societies from assemblages of shells or stone artefacts in dispersed sites deposited over tens of thousands of years. The authors demonstrate the perilous connections between the distribution and content of sites, their geomorphic formation process and the models used to analyse them. In particular they warn against extrapolating the enticing evidence from Pleistocene Willandra into behavioural patterns by drawing on the models presented by nineteenth-century anthropologists. They propose new strategies at once more revealing and more ethical.
LISPB revisited: a new look under the Caledonides of northern Britain

SUMMARY The Lithospheric Seismic Profile in Britain (LISPB), shot in 1974, included a 700 km long north-south profile of the crust and upper mantle of northern Britain. The wide-angle seismic data from LISPB was of exceptional quality and coverage making a reinterpretation using current modelling programs worthwhile. This reinterpretation shows that the original crustal model published by Bamford et al. (1978) satisfies the observed first arrival traveltimes, but that further detail of crustal velocity structure may be obtained by model shows strong variations in crustal velocity structure that appear to be correlated with geological and tectonic structures mapped at the surface. The new lithospheric model is compatible with the observed gravity field when converted to appropriate densities, and the variations in loading along the base of the density model show that the lithosphere is close to local isostatic equilibrium. Profiles of the variation of velocity and density with depth from the new model are compared with measurements of Lewisian rocks made at confining pressures up to 8 kbar, allowing the seismic model to be interpreted geologically. A synthetic normal incidence profile of the new model is superimposed on the nearby NEC deep seismic reflection profile, and the features imaged by the two techniques are compared.
Entropy measures and unconditional security in cryptography

One of the most important properties of a cryptographic system is a proof of its security. In the present work, information-theoretic meth¬ ods are used for proving the security of unconditionally secure cryptosystems. The security of such systems does not depend on unproven intractability assumptions. A survey of entropy measures and their applications in cryptography is presented. A new information measure, smooth entropy, is intro¬ duced to quantify the number of almost uniform random bits that can be extracted from a source by probabilistic algorithms. Smooth entropy unifies previous work on privacy amplification in cryptography and on entropy smoothing in theoretical computer science. It enables a system¬ atic investigation of the spoiling knowledge proof technique to obtain lower bounds on smooth entropy. The Renyi entropy of order at least 2 of a random variable is a lower bound for its smooth entropy, whereas an assumption about Renyi entropy of order 1, which is equivalent to the Shannon entropy, is too weak to guarantee any non-trivial amount of smooth entropy. The gap between Renyi entropy of order 1 and 2 is closed by proving that Renyi entropy of order a between 1 and 2 is a lower bound for smooth entropy, up to a small parameter depending on a, the alphabet size, and the failure probability. The operation of many unconditionally secure cryptosystems can be divided into the three phases advantage distillation, information recon¬ ciliation, and privacy amplification. The relation between privacy am¬ plification and information reconciliation is investigated, in particular, the effect of side information, obtained by an adversary through an ini¬ tial reconciliation step, on the size of the secret key that can be distilled safely by subsequent privacy amplification. It is shown that each bit of side information reduces the size of the key that can be generated by at
