description: Recently the ATLAS and CMS experiments have presented data hinting at the presence of a Higgs boson at $m_h\simeq125$ GeV. The best-fit $h\rightarrowγγ$ rate averaged over the two experiments is approximately $2.1\pm0.5$ times the Standard Model prediction. We study the possibility that the excess relative to the Standard Model is due to $h\rightarrow aa$ decays, where $a$ is a light pseudoscalar that decays predominantly into $γγ$. Although this process yields $4γ$ final states, if the pseudoscalar has a mass of the order tens of MeV, the two photons from each $a$ decay can be so highly collimated that they may be identified as a single photon. Some fraction of the events then contribute to an effective $h\rightarrowγγ$ signal. We study the constraints on the parameter space where the net $h\rightarrowγγ$ rate is enhanced over the Standard Model by this mechanism and describe some simple models that give rise to the pseudoscalar-photon interaction. Further tests and prospects for searches in the near future are discussed.

description: The city of Louga, Senegal, represents one of 11 African cities participating in the Earth Institute at Columbia University's Millennium Cities Initiative (MCI). Complementing the already established Millennium Villages Project, the objectives of MCI are to help underserved sub-Saharan cities achieve the Millennium Development Goals (MDGs), attract foreign direct investment and design an urban development strategy that will result in economic growth and social sector improvements. With a population of just under 100,000, Louga is the smallest of the Millennium Cities; however, as a regional capital with strong economic ties to its rural surroundings, Louga epitomizes the situation in many sub-Saharan cities, serving, therefore, as an excellent and extremely telling model for the MCI. The specific goal of this needs assessment was to examine the status of the healthcare system in Louga and to gather the information required to bring about change that will be beneficial to the health of the population. The three health-specific MDGs – to reduce child mortality, improve maternal health and combat HIV/AIDS, malaria and other diseases – acted as the criteria for determining progress. Data collection occurred from May - July 2008 in Louga and, to a much smaller degree, in Dakar. The needs assessment utilized local administrative records where possible, with regional and national data estimations employed only where necessary. The use of the UN-Millennium Project health costing tool allowed for a detailed cost projection, estimating the amount of financial investment required to assist the city of Louga in achieving the health-specific MDGs from 2010 - 2015. Organized into five main sections, this report provides a comprehensive assessment of the public health situation in Louga and the costs associated with achieving the MDGs before 2015. The first introductory section reviews necessary background information, methodology and limitations; next, a description of the Senegalese health care system provides a context for the critical elements of this report – the analysis of each health-specific MDG in Louga. Finally, concluding remarks synthesize the researcher's findings and present some final comments and recommendations.
Magnetization of cloud cores and envelopes and other observational consequences of reconnection diffusion

description: Recent observational results for magnetic fields in molecular clouds reviewed by Crutcher (2012) seem to be inconsistent with the predictions of the ambipolar diffusion theory of star formation. These include the measured decrease in mass to flux ratio between envelopes and cores, the failure to detect any self-gravitating magnetically subcritical clouds, the determination of the flat PDF of the total magnetic field strengths implying that there are many clouds with very weak magnetic fields, and the observed scaling $B \propto ρ^{2/3}$ that implies gravitational contraction with weak magnetic fields. We consider the problem of magnetic field evolution in turbulent molecular clouds and discuss the process of magnetic field diffusion mediated by magnetic reconnection. For this process that we termed "reconnection diffusion" we provide a simple physical model and explain that this process is inevitable in view of the present day understanding of MHD turbulence. We address the issue of the expected magnetization of cores and envelopes in the process of star formation and show that reconnection diffusion provides an efficient removal of magnetic flux that depends only on the properties of MHD turbulence in the core and the envelope. As a result, the magnetic flux trapped during the collapse in the envelope is being released faster than the flux trapped in the core, resulting in much weaker fields in envelopes than in cores, as observed. We provide simple semi-analytical model calculations which support this conclusion and qualitatively agree with the observational results. We argue that magnetic reconnection provides a solution to the magnetic flux problem of star formation that agrees better with observations than the long-standing ambipolar diffusion paradigm.

Die Ergebnisse weisen auf eine hohe Berufszufriedenheit. Allerdings sind durchaus auch Einschränkungen der Zufriedenheit zu verzeichnen, die teilweise auf die typische Arbeitskultur in IT-Berufen zurückzuführen sind. Daneben wird das Arbeitsklima zwischen  Männern und Frauen durchaus unterschiedlich wahrgenommen, auch der Wunsch nach einem ausgewogenen Verhältnis von Arbeits- und Privatleben (work/life balance) zeigt Unterschiede zwischen Männern und Frauen. Insgesamt lassen sich aus den Ergebnissen Hinweise ableiten, durch welche Maßnahmen das Studium und die Berufstätigkeiten in IT-Berufen attraktiver gestaltet werden und damit dem Fachkräftemangel entgegengewirkt werden kann.

description: We consider an electro-weak scale model for Dark Matter (DM) and radiative neutrino mass generation. Despite the leptophilic nature of DM with no direct couplings to quarks and gluons, scattering with nuclei is induced at the 1-loop level through photon exchange. Effectively, there are charge-charge, dipole-charge and dipole-dipole interactions. We investigate the parameter space consistent with constraints from neutrino masses and mixing, charged lepton-flavour violation, perturbativity, and the thermal production of the correct DM abundance, and calculate the expected event rate in DM direct detection experiments. We show that current data from XENON100 start to constrain certain regions of the allowed parameter space, whereas future data from XENON1T has the potential to significantly probe the model.

description: Many recent models of trade dynamics use the simple idea of wealth exchanges among economic agents in order to obtain a stable or equilibrium distribution of wealth among the agents. In particular, a plain analogy compares the wealth in a society with the energy in a physical system, and the trade between agents to the energy exchange between molecules during collisions. In physical systems, the energy exchange among molecules leads to a state of equipartition of the energy and to an equilibrium situation where the entropy is a maximum. On the other hand, in the majority of exchange models, the system converges to a very unequal condensed state, where one or a few agents concentrate all the wealth of the society while the wide majority of agents shares zero or almost zero fraction of the wealth. So, in those economic systems a minimum entropy state is attained. We propose here an analytical model where we investigate the effects of a particular class of economic exchanges that minimize the entropy. By solving the model we discuss the conditions that can drive the system to a state of minimum entropy, as well as the mechanisms to recover a kind of equipartition of wealth.
Asymptotic properties of wall-induced chaotic mixing in point vortex pairs

Publisher: name: arXiv
Year: 2011
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: The purpose of this work is to analyze the flow due to a potential point vortex pair in the vicinity of a symmetry line (or "wall"), in order to understand why the presence of the wall, even far from the vortices, accelerates fluid mixing around the vortex pair. An asymptotic analysis, in the limit of large distances to the wall, allows to approximate the wall effect as a constant translation of the vortex pair parallel to the wall, plus a straining flow which induces a natural blinking vortex mechanism with period half the rotation period. A Melnikov analysis of lagrangian particles, in the frame translating and rotating with the vortices, shows that a homoclinic bifurcation indeed occurs, so that the various separatrices located near the vortex pair (and rotating with it) do not survive when a wall is present. The thickness of the resulting inner stochastic layer is estimated by using the separatrix map method, and is shown to scale like the inverse of the squared distance to the wall. This estimation provides a lower-bound to the numerical thickness measured from either Poincaré sections or simulations of lagrangian particles transported by the exact potential velocity field in the laboratory frame. In addition, it is shown that the outer homoclinic cycle, separating the vortices from the external (open) flow, is also perturbed from inside by the rotation of the vortex pair. As a consequence, a stochastic layer is shown to exist also in the vicinity of this cycle, allowing fluid exchange between the vortices and the outer flow. However, the thickness of this outer stochastic zone is observed to be much smaller than the one of the inner stochastic zone near vortices, as soon as the distance to the wall is large enough.

description: This paper discusses the benefits and risks that financial globalization entails for developing countries. Financial globalization can lead to large benefits, particularly to the development of the financial system. But financial globalization can also come with crises and contagion. The net effect of financial globalization is likely positive in the long run, with risks being more prevalent right after countries liberalize. So far, only some countries, sectors, and firms have taken advantage of globalization. As financial systems turn global, governments lose policy instruments, so there is an increasing scope for some form of international financial policy cooperation.
Search for supersymmetry in events with three leptons and missing transverse momentum in sqrt(s) = 7 TeV pp collisions with the ATLAS detector

description: A search for the weak production of charginos and neutralinos into final states with three electrons or muons and missing transverse momentum is presented. The analysis uses 2.06 fb^-1 of sqrt(s) = 7 TeV proton-proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with standard model expectations in two signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric and simplified models. For the simplified models, degenerate lightest chargino and next-to-lightest neutralino masses up to 300 GeV are excluded for mass differences from the lightest neutralino up to 300 GeV.

Nonlinear wavelength selection in surface faceting under electromigration

description: We report on the control of the faceting of crystal surfaces by means of surface electromigration. When electromigration reinforces the faceting instability, we find perpetual coarsening with a wavelength increasing as $t^{1/2}$. For strongly stabilizing electromigration, the surface is stable. For weakly stabilizing electromigration, a cellular pattern is obtained, with a nonlinearly selected wavelength. The selection mechanism is not caused by an instability of steady-states, as suggested by previous works in the literature. Instead, the dynamics is found to exhibit coarsening {\it before} reaching a continuous family of stable non-equilibrium steady-states.

description: Proximity coupled spin-orbit quantum wires have recently been shown to support midgap Majorana states at critical points. We show that in the presence of disorder these systems are prone to the buildup of a second bandcenter anomaly, which is of different physical origin but shares key characteristics with the Majorana state: it is narrow in width, insensitive to magnetic fields, carries unit spectral weight, and is rigidly tied to the band center. Depending on the parity of the number of subgap quasiparticle states, a Majorana mode does or does not coexist with the impurity generated peak. The strong 'entanglement' between the two phenomena may hinder an unambiguous detection of the Majorana by spectroscopic techniques.

description: The trade deficit, which together with the budget deficit constitutes one side of America's "twin deficits," is still an enormous sum. Since Japan accounts for one third of the trade deficit, one has to pay close attention to it in the sense that the deficit trend forecasts the future of U.S.-Japan economic friction. The trade deficit's continuation became a headache for Washington's policy makers as well as something beyond the predictions of economists and academics. In general they saw this phenomenon as something running counter to "theory," or as nothing more than a sign that the dollar's fall had been insufficient. Such macroeconomic approaches as the bilateral comparison of the balance of savings and consumption provide a large framework for explaining America's trade deficit. However, paying attention to the kinds of changes which occurred in American industry in the period in which were adopted exceptional policies to stimulate a consumption which left behind huge budget deficits should provide one with a clue. Although these changes were in some sense irreversible, they were not noticed as such at the time.

description: Team climate is a construct that has been researched extensively with business teams and has been shown to be positively correlated with performance. The business world and the sporting world have many similarities, so a logical step forward would be to explore whether the construct is present in sport. The Team Climate Questionnaire for Sport was developed to examine whether team climate is a salient construct amongst sports teams. An exploratory factor analysis was performed, resulting in a seven factor solution. Many of the factors were directly related to the previous factors extracted in business research. Correlations with existing sport specific questionnaires, the Group Environment Questionnaire and the Athlete Satisfaction Questionnaire (GEQ & ASQ) were undertaken in order to determine if the new questionnaire was able to measure different constructs. The TCQS displayed strong psychometric properties overall and results indicated that it shows promise for measuring the construct of team climate in sports teams. Further examination of the TCQS is justified in order to confirm the factor structure and refine the format.

description: Computernetzwerke sind schon seit vielen Jahren ein nicht mehr wegzudenkender Teil der Infrastruktur nahezu aller Unternehmen und Institutionen. Sie werden genutzt um sowohl öffentliche als auch private und sicherheitskritische Informationen bereitzustellen. Aus diesem Grund ist die Netzwerksicherheit immer ein relevantes Thema, das sehr viele Aspekte hat. Neben einer gesicherten Übertragung von Daten, ist die Netzwerkzugriffskontrolle ein wichtiger Teil der Netzwerksicherheit. Insbesondere für öffentlich zugängliche Institutionen, wie die Hochschule Hannover, ist es wichtig, den Netzwerkzugriff zu beschränken. Zur Zeit wird im kabelgebundenen Netzwerk der Abteilung Informatik der Hochschule Hannover ein Sicherheitskonzept auf Basis von MAC-Adressen genutzt. Dieses Konzept bietet nur ein geringes Maß an Sicherheit und hält einem gezielten Angriff nicht Stand. Eine effektive Netzwerkzugriffskontrolle findet nicht statt. Eine bessere Alternative ist der Standard IEEE 802.1X, der eine Netzwerkzugriffskontrolle unter Verwendung verschiedener Authentifizierungsmethoden ermöglicht. Das Ziel dieser Arbeit ist die Erstellung eines Konzepts für die Implementierung dieses Standards im Netzwerk der Abteilung Informatik. Dieses Konzept soll gewährleisten, dass ein Netzwerkzugriff ausschließlich für autorisierte Geräte und Personen möglich ist. Zu diesem Zweck wird analysiert, welche Teile des Netzwerks von 802.1X profitieren und welche Authentifizierungsmethoden sich für diese am besten eignen. Bei der Erstellung des Konzepts werden unterschiedliche Möglichkeiten zum Umgang mit Geräten ohne Unterstützung für den 802.1X-Standard geprüft. Darüberhinaus wird auch eine Hochverfügbarkeitslösung für den Authentifizierungsdienst erarbeitet, um sicherzustellen, dass ein Netzwerkzugriff auch nach der Implementierung von 802.1X jederzeit möglich ist. Abschließend wird die Realisierbarkeit des Konzepts durch die Implementierung in einer Testumgebung geprüft.

Five studies in life history evolution

Publisher: name: University of British Columbia

description: Assortative mating by fitness has the potential population-level benefit of reducing migration load during times of environmental stasis, while allowing introgression of immigrant genetic variation in the event of environmental change. Assortative mating by fitness was examined with respect to within-population spread of a recombination modifier under selective sweep and mutation-selection balance scenarios. Only the latter scenario boosted modifier frequency, given a strength of assortative mating unlikely to be present in most species. In a second attempt to identify a new general advantage for sexual reproduction, the focus was on how inter-individual reproduction might reduce noise in inheritance and increase the power of selection. Individuals can experience good and bad "luck" at various stages of their life history, in any habitat, and it was found that combining gametes from two separate experiences of this ecological noise could indeed reduce noise in inheritance. The puzzle of small mammal population density cycles was approached from an evolutionary, rather than a population regulation perspective. An appropriate pattern of reproductive effort would seem key to survival through repeated population crashes to low numbers. Small mammals reproduce below their apparent potential through the decline and into the low phase of a cycle, and determining whether this reproductive pattern is adaptive is an important question. A standard cycling analytical model, the Rosenzweig-MacArthur, was carefully examined for the basis of this life history work, and found wanting even after considering several modifications. So an individual-based simulation was done. For simplicity and generality a novel mechanism was used: the "cumulative recent activity" of a population predicts several mortality causes, and has the property of delayed density dependence required to drive cycles. If animals cue from this quantity, then some controversy-causing experimental results might be explained. Branching theory and the simulation model showed that reproductive slowdown evolves under high mortality rates and, given a premium on short term persistence such as might exist at low numbers or densities, at low mortality rates. This explains the reproductive pattern observed in cycling mammals. The known reproductive suppression by stress physiology now appears to be adaptive, rather than inadvertent.

description: In this study, a model that draws upon the Resource-Demand perspective, Karasek' s Job Demands-Control theory and Role theory was developed to understand the determinants of work-to-family and work-to-parent conflict. Hypotheses about the effects of work and family demands and resources and gender, were tested using secondary data from 646 Alberta lawyers. Results suggest that work domain variables are important for understanding work-to-family conflict. While family demands did not significantly contribute to work-to-family conflict, family resources such as paid help with childcare and housework, were important in moderating the harmful effects of work and family demands on work-to-family conflict. The model was less successful in explaining work-to-parent conflict and it was proposed that work-to-parent conflict may be better understood as an outcome of work-to-family conflict. More research is needed to investigate this possibility, as well as to understand why women experience more work-to-family and work-to-parent conflict than men.

description: Validating experimental results from articles has finally become a norm at many HPC and systems conferences. Nowadays, more than half of accepted papers pass artifact evaluation and share related code and data. Unfortunately, lack of a common experimental framework, common research methodology and common formats places an increasing burden on evaluators to validate a growing number of ad-hoc artifacts. Furthermore, having too many ad-hoc artifacts and Docker snapshots is almost as bad as not having any (!), since they cannot be easily reused, customized and built upon.

While overviewing more than 100 papers during artifact evaluation at HPC conferences, we noticed that many of them use similar experimental setups, benchmarks, models, data sets, environments and platforms. This motivated us to develop Collective Knowledge (CK), an open workflow framework with a unified Python API to automate common researchers’ tasks such as detecting software and hardware dependencies, installing missing packages, downloading data sets and models, compiling and running programs, performing autotuning and co-design, crowdsourcing time-consuming experiments across computing resources provided by volunteers similar to SETI@home, reproducing results, automatically generating interactive articles, and so on: http://cKnowledge.org .

In this talk I will introduce CK concepts and present several real world use cases from the Raspberry Pi foundation, ACM, General Motors, Amazon and Arm on collaborative benchmarking, autotuning and co-design of efficient software/hardware stacks for emerging workloads including deep learning. I will also present our latest initiative to create an open repository of reusable research components and workflows at HPC conferences. We plan to use it to automate the Student Cluster Competition Reproducibility Challenge at the Supercomputing conference.

The intra-daily exchange rate dynamics and monetary policies after the G5 agreement
Creators: name: Ito, Takatoshi
Publisher: name: Columbia University
Year: 1987
Subjects: Economics
Commerce

description: This short paper focuses on the three main dimensions of the U.S.-Japan trade relationship: macroeconomic, namely the overall immense respective trade and current account deficits and surpluses; microeconomic, namely sectoral issues of American business access to Japanese markets (and, less marred by bilateral frictions but of systemic importance, the nature of restrictions of Japanese access to U.S. markets); and systemic, namely the way in which the resolution of bilateral trade issues affect the rules of the game and nature of the GATT-based, multilateral, relatively open international trading system. Recent trends and their causes are assessed, as are current policy issues and actions, and the important implications are drawn. In the final section the effects on other Pacific Basin economies are considered; that discussion is relevant for the world as a whole though the management of the U.S.-Japan trade relationship has a particularly large Pacific Basin impact.
The problem of shot selection in basketball

description: In basketball, every time the offense produces a shot opportunity the player with the ball must decide whether the shot is worth taking. In this paper, I explore the question of when a team should shoot and when they should pass up the shot by considering a simple theoretical model of the shot selection process, in which the quality of shot opportunities generated by the offense is assumed to fall randomly within a uniform distribution. I derive an answer to the question "how likely must the shot be to go in before the player should take it?", and show that this "lower cutoff" for shot quality $f$ depends crucially on the number $n$ of shot opportunities remaining (say, before the shot clock expires), with larger $n$ demanding that only higher-quality shots should be taken. The function $f(n)$ is also derived in the presence of a finite turnover rate and used to predict the shooting rate of an optimal-shooting team as a function of time. This prediction is compared to observed shooting rates from the National Basketball Association (NBA), and the comparison suggests that NBA players tend to wait too long before shooting and undervalue the probability of committing a turnover.

Capital Market Liberalization, Poverty and Inequality
Creators: name: Cobham, Alex
Publisher: name: Columbia University
Year: 2004
Subjects: Managerial economics
Economics

description: Research has typically addressed capital account liberalisation in terms of its growth effects. While no systematic growth benefits have been identified, potentially damaging poverty and inequality impacts have been overlooked. This paper identifies a number of channels through which these may occur. For policymakers, these are: increased instability of government finances, restricted policy freedom through "market discipline" and the direct costs of managing inflows. Financial market and industrial structure effects include: greater volatility in access to finance for households and small businesses, increasing industrial concentration and shifts in taxation away from capital and towards labour and consumption. The paper makes a number of suggestions to address these potential dangers of liberalisation. These include measures to encourage the taking of longer-term positions in developing country markets by institutional investors in richer countries, and support for reserve requirements on capital inflows. The paper finally argues that requirements for equal treatment of investors (in WTO negotiations or elsewhere) should be resisted, where this is likely to prevent policymakers taking a selective approach to foreign direct investment.

description: In this thesis, the transport properties and relaxation phenomena in 1D interacting
systems are studied. The electrical transport is investigated in Josephson junction (JJ) chains which show
the remarkable phenomenon of a superconductor-insulator transition. These systems also offer
the possibility to examine relaxation phenomena: we consider the decay of excited plasmonic
waves in such devices. In addition to the relaxation of bosonic excitations in JJ chains, we dis-
cuss the relaxation of high-energy fermions in quantum wires.

description: Die Generation der ab den 1980er Jahren Geborenen, genannt Generation Y, tritt seit einiger Zeit als Arbeitnehmer in die Arbeitsmärkte ein. Im Jahr 2020 wird diese Gruppe die Hälfte der Arbeitnehmer in der Bundesrepublik ausmachen. Lebensstil, Globalisierung, kulturelles und mediales Angebot führen bei dieser Generation auch in der Arbeitswelt zu anderen Erwartungen und Ansprüchen als dies bei vorherigen Generationen der Fall war. In Literatur und Studien wird diese Generation fast ausschließlich als selbstbewusst, ehrgeizig, aufstrebend, sozial engagiert und mobil beschrieben. Vor dem Hintergrund des zu erwartenden Fachkräftemangels widmet sich diese Arbeit unter anderem der Frage, mit welchen Instrumenten das Personalmanagement der Unternehmen auf diese Situation reagieren kann, um bei der Gewinnung und Bindung von Mitarbeitern erfolgreich zu sein.
