description: This contribution begins the study of the complete superfield Lagrangian description of the interacting system of D=4 N=1 supergravity (SUGRA) and supermembrane. Firstly, we review a 'three form supergravity' by Ovrut and Waldram, which we prefer to call 'special minimal supergravity'. This off-shell formulation of simple SUGRA is appropriate for our purposes as the supermembrane action contains the so-called Wess-Zumino term given by the integral over a three form potential in superspace, C3. We describe this formulation in the frame of Wess--Zumino superfield approach, showing how the basic variations of minimal SUGRA are restricted by the conditions of the existence of a three-form potential C3 in its superspace. In this language the effect of dynamical generation of cosmological constant, known to be characteristic for this formulation of SUGRA, appears in its superfield form, first described by Ogievetsky and Sokatchev in their formulation of SUGRA as a theory of axial vector superfield. Secondly, we vary the supermembrane action with respect to the special minimal SUGRA superfields (basic variations) and obtain the supercurrent superfields as well as the supergravity superfield equations with the supermembrane contributions.

Saving-Investment Balance and Fiscal Sustainability of Japan: A View from the JGB Market

Finance

description: This paper provides an overview of the sustainability of Japan’s government debt, emphasizing the viewpoint of market participants in the Japanese government bonds (JGB) market. The Japanese government will be able to finance its debt as long as current surpluses continue, meaning there is sufficient domestic demand for JGB. Looking at domestic investors’ portfolio choices, both life insurance companies and pension funds are increasing their holdings of long-term government bonds to match the maturities of their assets and their payments to households. Japanese banks, on the other hand, are increasing their holdings of short-term government debt, almost proportionally to the increase in their deposits. However, there is substantial heterogeneity in portfolio choice. Three megabank groups (Mitsubishi–Tokyo–UFJ, Mizuho, Sumitomo–Mitsui) and large regional banks have decreased their portfolio weights of JGB recently. Smaller banks specializing in small-firm lending and agricultural lending as well as Japan Post Bank (Yu-cho) have increased the proportion of government debt in their portfolios. Hence, potential losses in their portfolios, once the JGB yield starts to increase, are much higher with the latter group of financial institutions.

description: Observations with the Plateau de Bure Interferometer in the most extended configuration toward two intermediate-mass star-forming regions, IRAS22198+6336 and AFGL5142, reveal the presence of several complex organic molecules at ~500 AU scales, confirming the presence of hot cores in both regions. The hot cores are not rich in CN-bearing molecules, as often seen in massive hot cores, and are mainly traced by CH3CH2OH, (CH2OH)2, CH3COCH3, and CH3OH, with additionally CH3CHO, CH3OD and HCOOD for IRAS22198+6336, and C6H, and O13CS for AFGL5142. The emission of complex molecules is resolved down to sizes of ~300 and ~600 AU, for IRAS22198+6336 and AFGL5142, respectively, and most likely is tracing protostellar disks rather than flattened envelopes or toroids as usually found. This is specially clear for the case of IRAS22198+6336, where we detect a velocity gradient for all the mapped molecules perpendicular to the most chemically rich outflow of the region, yielding a dynamic mass >4 Msun. As for AFGL5142, the hot core emission is resolved into two elongated cores separated 1800 AU. A detailed comparison of the complex molecule peaks to the new CO(2-1) data and H2O maser data from literature suggests that also for AFGL5142 the complex molecules are mainly associated with disks, except for a faint and extended molecular emission found to the west, which is possibly produced in the interface between one of the outflows and the dense surrounding gas.

description: This paper combines insights from A Behavioral Theory of the Firm and Neo-Institutional Theory to provide a more comprehensive understanding of how new practices are adopted and transformed. The setting is the spread of the Executive Officer System (EOS) in the Japanese electronics industry. While this system, based on the Anglo-American system of governance, was designed to separate executive and monitoring, in reality, firms that reduced the size of the board only, leaving membership heavily weighted to executive officers. Based on a combination of qualitative and quantitative studies, we argue that this is not merely decoupling or symbolic management; rather, the legitimacy of the EOS system made it readily accessible and salient to firms searching for a solution to problems in decision-making. The legitimacy of EOS as the “global standard” of corporate governance enabled top executives to frame difficult board reforms to internal actors. Through adoption of EOS, firms were able to “kill two birds with one stone” by appealing to investors as well as solving internal problems. This research contributes to our understanding of diffusion and variation, the nature of decoupling, global spread of Anglo-American corporate governance, and NIT and BTF accounts of diffusion of new practices.

description: When developing strategies or policies to increase resilience, private and public decision makers need to anticipate to future shocks and stresses affecting the systems they manage. However, they face the difficulty that the future is not fully known. Uncertainty exists with respect to key factors affecting the actions of interest. Scenarios are a useful tool to cope with such future uncertainties and can be used both as a way to explore—not predict—the future through the identification of potential opportunities and threats and as a way to make action more future-proof. The objective of this deliverable is to develop medium- to long-term explorative scenarios describing possible futures for the external environment that EU farming systems face. The external environment will include environmental issues, economic issues and social issues. Consumer trends are typically not or insufficiently included in farming systems related scenarios and will therefore get particular attention. The purpose is to produce scenarios that encompass a wide range of issues characterised in both a quantitative and a qualitative way that can be used to guide further work in SURE-Farm.

description: Relatively little attention has been given to understanding the fault recovery characteristics and performance tuning of native IP multicast networks. This paper focuses on the interaction of the component protocols to understand their behavior in network failure and recovery scenarios. We consider a multicast environment based on the Protocol Independent Multicast (PIM) routing protocol, the Internet Group Management Protocol (IGMP) and the Open Shortest Path First (OSPF) protocol. Analytical models are presented to describe the interplay of all of these protocols in various multicast channel recovery scenarios. Quantitative results for the recovery time of IP multicast channels are given as references for network configurations, and protocol development. Simulation models are developed using the OPNET simulation tool to measure the fault recovery time and the associated protocol control overhead, and study the influence of important protocol parameters. A testbed with five Cisco routers is configured with PIM, OSPF, and IGMP to measure the multicast channel failure and recovery times for a variety of different link and router failures. In general, the failure recovery is found to be light-weight in terms of control overhead and recovery time. Failure recovery time in a WAN is found to be dominated by the unicast protocol recovery process. Failure recovery in a LAN is more complex, and strongly influenced by protocol interactions and implementation specifics. Suggestions for improvement of the failure recovery time via protocol enhancements, parameter tuning, and network configuration are provided.

description: Over the past few years, governments and non-state groups in the Middle East and North Africa have gone to great lengths to build cyber capabilities. The proliferation of cyber weapons in the region and their use as geopolitical tools has the potential to further shake and unsettle regional crises and larger Western interests.

The biggest risk for Western powers is to leave any doubt about their readiness to retaliate or to support their allies against any actors’ cyber aggressions. As actors around the world begin to grasp the opportunities offered by conducting geopolitical operations in cyberspace, the window for showing this readiness is small and closing.
Indiscipline, punishment, gender and race : examining Discipline and Punish in the context of the prison systems of the United States, and England and Wales
Creators: name: Pemberton, Sarah
Publisher: name: University of British Columbia
Year: 2011

description: This dissertation explores how the changing philosophy and practices of criminal punishment in the United States, England and Wales reflect broader techniques and relations of power in these societies. Two questions motivate this research: firstly, the extent to which Michel Foucault’s account of power and the prison is applicable now; and secondly, whether Foucault's later work provides an adequate conceptual framework for theorizing the aspects of power that he either overlooks or inadequately addresses in Discipline and Punish. I identify three trends in criminal justice over recent decades that challenge Foucault's account of penality: sharply rising incarceration rates, prison privatization, and the racialized and gendered nature of prison populations. I argue that although Foucault's concept of disciplinary power remains applicable, a fuller understanding of contemporary penality requires an analysis of how race and gender are constituted through biopower, and of how neoliberalism has shaped penal policy and contributed to greater socioeconomic inequality. Although I conclude that Foucault's theorization of power and the prison in Discipline and Punish is inadequate in light of the racialized and gendered nature of power relations in both historical and contemporary criminal justice systems, I draw on his later work to re-theorize power and inequality. I argue that Foucault's analysis of sex, sexuality, and race provides a valuable conceptual framework that generates important insights, particularly through the concepts of biopower and state racism. However, I critique aspects of Foucault's later work, arguing that his analysis of race is inattentive to the inter-relation of race, class and capitalism; that his analysis of sex and sexuality overlooks the question of gender; and that his account of neoliberalism is more descriptive than analytical. I therefore combine the conceptual framework provided by Foucault with insights from feminist theory, queer theory and critical race theory to show how racialized, gendered and sexed identities become constituted within institutions such as the prison. My conclusion is that criminal justice and prison systems serve to construct and reinforce racialized and gendered identities, and thereby contribute to racialized and gendered inequalities that extend far beyond the prison system.

description: In this study, we address the phase coherent transport in a sub-micrometer-sized Hall bar made of epitaxial Bi2Se3 thin film by probing the weak antilocalization (WAL) and the magnetoresistance fluctuation below 22 K. The WAL effect is well described by the Hikami-Larkin-Nagaoka model, where the temperature dependence of the coherence length indicates that electron conduction occurs quasi-one-dimensionally in the narrow Hall bar. The temperature-dependent magnetoresistance fluctuation is analyzed in terms of the universal conductance fluctuation, which gives a coherence length consistent with that derived from the WAL effect.

description: In classical random matrix theory the Gaussian and chiral Gaussian random matrix models with a source are realized as shifted mean Gaussian, and chiral Gaussian, random matrices with real $(β= 1)$, complex ($β= 2)$ and real quaternion $(β= 4$) elements. We use the Dyson Brownian motion model to give a meaning for general $β> 0$. In the Gaussian case a further construction valid for $β> 0$ is given, as the eigenvalue PDF of a recursively defined random matrix ensemble. In the case of real or complex elements, a combinatorial argument is used to compute the averaged characteristic polynomial. The resulting functional forms are shown to be a special cases of duality formulas due to Desrosiers. New derivations of the general case of Desrosiers' dualities are given. A soft edge scaling limit of the averaged characteristic polynomial is identified, and an explicit evaluation in terms of so-called incomplete Airy functions is obtained.

description: Privacy in the context of ubiquitous social computing systems has become a major concern for the society at large. As the number of online social computing systems that collect user data grows, this privacy threat is further exacerbated. There has been some work (both, recent and older) on addressing these privacy concerns. These approaches typically require extra computational resources, which might be beneficial where privacy is concerned, but when dealing with Green Computing and sustainability, this is not a great option. Spending more computation time results in spending more energy and more resources that make the software system less sustainable. Ideally, what we would like are techniques for designing software systems that address these privacy concerns but which are also sustainable - systems where privacy could be achieved "for free," i.e., without having to spend extra computational effort. In this paper, we describe how privacy can be achieved for free - an accidental and beneficial side effect of doing some existing computation - and what types of privacy threats it can mitigate. More precisely, we describe a "Privacy for Free" design pattern and show its feasibility, sustainability, and utility in building complex social computing systems.

description: We present a microscopic study of the nuclear magnetic relaxation rate 1/T1 based on the five-orbital model for iron-based superconductors. We mainly discuss the effect of the "inelastic" quasi-particle damping rate γ due to many-body interaction on the size of the coherence peak, for both s++ and s+- wave superconducting states. We focus on Ba(Fe1-xCox)2As2, and systematically evaluate γ in the normal state from the experimental resistivity, from optimally to over-doped compounds. Next, γ in the superconducting state is calculated microscopically based on the second order perturbation theory. In optimally doped compounds (Tc ~ 30 K), it is revealed that the coherence peak on 1/T1T is completely suppressed due to large γ for both s++ and s+- wave states. On the other hand, in heavily over doped compounds with Tc < 10 K, the coherence peak could appear for both pairing states, since γ at Tc is quickly suppressed in proportion to Tc^2. By making careful comparison between theoretical and experimental results, we conclude that it is difficult to discriminate between s++ and s+- wave states from the present experimental results.

A Non-Deterministic Approach to Restructuring Flow Graphs

Publisher: name: Columbia University

Subjects: Computer science

description: The history of programming is filled with works about the properties of program flow graphs. There are many approaches to defining the quality of such graphs, and to improving a given flow graph by restructuring the underlying source code. We present here a new, twofold approach to restructuring the control flow of arbitrary source code. The first part of the method is a classical deterministic algorithm; the second part is non-deterministic and involves user interaction. The method is based on node splitting, enabling it to satisfy the definition of the extended Nassi-Shneiderman diagrams.

description: Dirac electrons in graphene in the presence of Coulomb interactions of strength $β$ have been shown to display power law behavior with $β$ dependent exponents in certain correlation functions, which we call the mass susceptibilities of the system. In this work, we first discuss how this phenomenon is intimately related to the excitonic insulator transition, showing the explicit relation between the gap equation and response function approaches to this problem. We then provide a general computation of these mass susceptibilities in the ladder approximation, and present an analytical computation of the static exponent within a simplified kernel model, obtaining $η_0 =\sqrt{1-β/β_c}$ . Finally we emphasize that the behavior of these susceptibilities provides new experimental signatures of interactions, such as power law Kohn anomalies in the dispersion of several phonons, which could potentially be used as a measurement of $β$.

description: Fraud and terrorism have a close connect in terms of the processes that enables and promote them. In the era of Internet, its various services that include Web, e-mail, social networks, blogs, instant messaging, chats, etc. are used in terrorism not only for communication but also for i) creation of ideology, ii) resource gathering, iii) recruitment, indoctrination and training, iv) creation of terror network, and v) information gathering. A major challenge for law enforcement and intelligence agencies is efficient and accurate gathering of relevant and growing volume of crime data. This paper reports on use of established Naïve Bayesian filter for classification of threat e-mails. Efficiency in filtering threat e-mail by use of three different Naïve Bayesian filter approaches i.e. single keywords, weighted multiple keywords and weighted multiple keywords with keyword context matching are evaluated on a threat e-mail corpus created by extracting data from sources that are very close to terrorism.

Domain wall annihilations create vortices while monopole-string annihilations result in instantons. We find that twisted domain wall rings are vortices, whereas twisted monopole rings are instantons.

description: We examine several effects of an applied magnetic field on Anderson-type models for both single- and two-level quantum dots, and make direct comparison between numerical renormalization group (NRG) calculations and recent conductance measurements. On the theoretical side the focus is on magnetization, single-particle dynamics and zero-bias conductance, with emphasis on the universality arising in strongly correlated regimes; including a method to obtain the scaling behavior of field-induced Kondo resonance shifts over a very wide field range. NRG is also used to interpret recent experiments on spin-1/2 and spin-1 quantum dots in a magnetic field, which we argue do not wholly probe universal regimes of behavior; and the calculations are shown to yield good qualitative agreement with essentially all features seen in experiment. The results capture in particular the observed field-dependence of the Kondo conductance peak in a spin-1/2 dot, with quantitative deviations from experiment occurring at fields in excess of $\sim$ 5 T, indicating the eventual inadequacy of using the equilibrium single-particle spectrum to calculate the conductance at finite bias.

description: The amount of data generated every day by online applications is continuously growing, which results in a demand for capable real-time stream processing frameworks. Numerous monitoring algorithms have been proposed over the years, yielding exceptional results but with common shortcomings. The problem not yet addressed by previous work on monitoring algorithms is their integration into large data-stream processing frameworks. Part of the reason
may be the lack of uniformity each monitoring algorithm presents and the requirements it imposes on the system architecture. That’s where Apache Flink comes into play. It is an open-source framework and distributed processing engine for stateful computation over unbounded data-streams. Flink is a very versatile tool, designed to run in all common cluster environments and perform computations at any scale. This thesis describes the implementation of the
Functional Geometric Monitoring algorithm on Apache Flink, while comparing the extracted results with these of previous simulated implementations of monitoring algorithms.

description: This paper presents 7DS, a novel peer-to-peer resource sharing system. 7DS is an architecture, a set of protocols and an implementation enabling the exchange of data among peers that are not necessarily connected to the Internet. Peers can be either mobile or stationary. We focus on three different facets of cooperation, namely, data sharing, message relaying and network connection sharing. 7DS enables wireless devices to discover, disseminate, relay information among each other to increase the data access. We evaluate via extensive simulations the effectiveness of our system for data dissemination and message relaying among mobile devices with a large number of user mobility scenarios. We model several general data dissemination approaches and investigate the effect of the wireless coverage range, 7DS host density, and cooperation strategy among the mobile hosts as a function of time. We also present a power conservation mechanism that is beneficial, since it increases the power savings, without degrading the data dissemination. Using theory from random walks, random environments and diffusion of controlled processes, we model one of these data dissemination schemes and show that the analysis confirms the simulation results for this scheme.

description: This study proposes a bioclimatic characterization and a new biogeographic division for the Antarctic territories up to the province level following the criteria and models of Rivas-Martínez et al. The Antarctic Kingdom comprises the continent of Antarctica, the surrounding ice-covered Antarctic islands, and the associated cold oceanic islands and archipelagos. It has two biogeographic regions: the Antarctic Region and the Subantarctic Insular Region. The Antarctic Region includes the entire pergelid Antarctic continent and the surrounding islands and archipelagos, and is characterized by upper suprapolar hyperoceanic and oceanic or Polar pergelid bioclimates on the coasts. The region has been divided into three pr6ovinces: Maritime Antarctica, West Antarctica and East Antarctica. The Subantarctic Insular Region comprises the circumantarctic islands and archipelagos that are widespread at the southern tip of the planet’s most important oceans, mostly in the subtemperate latitudinal zone inside or not far from the Antarctic Convergence. Bioclimatically, all insular subantarctic territories (excluding the South-American Tierra de Fuego, Terra Magellanica and large islands) are characterized by thermo-suprapolar and semipolar antarctic hyperoceanic bioclimates on the coasts. Four provinces – Falklandian-South Georgian, Kerguelenian, Macquarian and Aucklandian-Campbellian – have been recognized in this region. All these units are characterized by floristic bioindicators.

description: CAG trinucleotide repeats in androgen receptor (AR) gene encode a polyglutamine tract in AR N-terminal transactivation domain. Studies have been conducted to evaluate the effect of CAG repeat length on male infertility, which have yielded contradictory results. This study aimed to explore the number of AR-CAG repeats in 150 fertile controls and 150 idiopathic infertile men, divided into four azoospermia, oligozoospermia, asthenozoospermia, and teratozoospermia subgroups. In addition, a meta-analysis was conducted based on previous studies to assess the association of the mentioned variation with male infertility in recent years. Polymerase chain reaction (PCR) targeting followed by an electrophoresis on polyacrylamide gel was used for AR-CAG genotype detecting. Moreover, a systematic search was performed in PubMed, Web of Science, Science Direct, and Google Scholar databases to collect eligible studies for meta-analysis purpose. According to the results, a significant association was observed between increased length of AR-CAG polymorphism and male infertility (p< 0.0001). Furthermore, there were similar significant associations in the azoospermia (p= 0.048), asthenozoospermia (p= 0.013) and teratozoospermia (p= 0.002) subgroups. In addition, meta-analysis on forty studies showed a significant association between AR-CAG polymorphism in the overall analysis (SMD= 0.199, 95 % CI= 0.112-0.287, p

description: The increasing popularity of online courses has highlighted the need for collaborative learning tools for student groups. In addition, the introduction of lecture videos into the online curriculum has drawn attention to the disparity in the network resources available to students. We present an e-Learning architecture and adaptation model called AI2TV (Adaptive Interactive Internet Team Video), which allows groups of students to collaboratively view a video in synchrony. AI2TV upholds the invariant that each student will view semantically equivalent content at all times. A semantic compression model is developed to provide instructional videos at different level-of-details to accommodate dynamic network conditions and usersÃ¤Ã³Â» system requirements. We take advantage of the semantic compression algorithmÃ¤Ã³Â»s ability to provide different layers of semantically equivalent video by adapting the client to play at the appropriate layer that provides the client with the richest possible viewing experience. Video player actions, like play, pause and stop, can be initiated by any group member and and the results of those actions are synchronized with all the other students. These features allow students to review a lecture video in tandem, facilitating the learning process. Experimental trials show that AI2TV successfully synchronizes instructional videos for distributed students while concurrently optimizing the video quality, even under conditions of fluctuating bandwidth, by adaptively adjusting the quality level for each student while still maintaining the invariant.

description: In this paper, in terms of the relation between the state and the reduced states of it, we obtain two inequalities which are valid for all separable states in infinite-dimensional bipartite quantum systems. One of them provides an entanglement criterion which is strictly stronger than the computable cross-norm or realignment (CCNR) criterion.

description: Some species intrinsically have a high invasiveness capacity, shown by high phenotypic plasticity and rapid growth, enabling a wide distribution across their native habitats and successful invasion in the introduced range. For such species, information from native habitats is critically important. An example is Glechoma hederacea, native to Eurasia but introduced and widespread in the USA. Our main objective was to investigate variation in traits of native G. hederacea populations across contrasting habitats: open, forest edge and understory. Vegetation was sampled and the ecophysiological and morphological traits were measured with accompanying environmental parameters. Results showed that in native habitats environmental conditions cover wide gradients of light and soil moisture. Plants had the highest cover in nutrient-rich, shaded habitats, representing the optimal habitat, indicating shade tolerance of G. hederacea. Plants from forest understory exhibited strong similarities in investigated traits to plants from the forest edge, even though this was a drier, sunnier habitat. Plants from open, sunny habitats experienced stress as indicated by the quantum efficiency of PSII and significantly higher sexual reproduction. Results show that G. hederacea is moderately tolerant simultaneously to shade and drought, a characteristic that has been reported for numerous invasive species, while at the same time it shares some characteristics with weedy plants.

description: We investigate the scalar perturbation in the Lee-Wick bouncing universe driven by an ordinary scalar field plus a ghost field. We consider only a symmetric evolution of the universe and the scalar fields about the bouncing point. The gauge invariant Sasaki-Mukhanov variable is numerically solved in the spatially flat gauge. We find a new form of the initial perturbation growing during the contracting phase. After the bouncing, this growing mode stabilizes to a constant mode which is responsible for the late-time power spectrum.

Optimal stabilization policy when wages and prices are sticky: The case of a distorted steady state
Creators: name: Benigno, Pierpaolo

Year: 2004
Subjects: Economics

description: Erceg et al. (2000) show that when both wages and prices are sticky, maximization of expected utility is equivalent to minimizing a loss function with three terms, involving measures of the variability of wage inflation, price inflation and the output gap respectively. Here we generalize their analysis, most importantly by not assuming the existence of output and employment subsidies that eliminate the distortions resulting from market power in goods and labor markets, so that the equilibrium level of output under flexible wages and prices would not necessarily be optimal. We show that a quadratic loss function can still be justified that involves the same three terms, albeit with different relative weights and a different definition of the output gap. Many conclusions of Erceg et al. are thus found to apply more generally. However, we argue that in the presence of significant steady-state distortions, simple rules of the kind that they examine are likely to approximate optimal policy less closely than is suggested by their numerical results.

Combining Microarray Expression Data and Phylogenetic Profiles to Learn Gene Functional Categories Using Support Vector Machines

Subjects: Computer science

description: A primary goal in biology is to understand the molecular machinery of the cell. The sequencing projects currently underway provide one view of this machinery. A complementary view is provided by data from DNA microarray hybridization experiments. Synthesizing the information from these disparate types of data requires the development of improved computational techniques. We demonstrate how to apply a machine learning algorithm called support vector machines to a heterogeneous data set consisting of expression data as well as phylogenetic profiles derived from sequence similarity searches against a collection of complete genomes. The two types of data provide accurate pictures of overlapping subsets of the gene functional categories present in the cell. Combining the expression data and phylogenetic profiles within a single learning algorithm frequently yields superior classification performance compared to using either data set alone. However, the improvement is not uniform across functional classes. For the data sets investigated here, 23-element phylogenetic profiles typically provide more information than 79-element expression vectors. Often, adding expression data to the phylogenetic profiles introduces more noise than information. Thus, these two types of data should only be combined when there is evidence that the functional classification of interest is clearly reflected in both data sets.
