description: Abstract
We used the full-potential linearized augmented plane-wave method within the density functional theory framework to investigate the structural, elastic, electronic and magnetic properties of the rock-salt (B1) Sr0.75Mn0.25X (X = S, Se and Te). The Wu-Cohen generalized gradient approximation (WC-GGA) was used to describe the exchange-correlation potential. To get appropriate results about the electronic properties of Sr0.75Mn0.25X (X = S, Se and Te) alloys, the Tran-Blaha modified Becke-Johnson (TB-mBJ) potentials were also used. The experimental, theoretical results and our optimized equilibrium structural parameters are in good accord.  Our elastic constants Cij were used to calculate the bulk modulus B, shear modulus S, Young's modulus Y, Poisson's modulus ν, Pugh's ratio, acoustic velocities, and Debye temperature. It is confirmed that these compounds have brittleness and mechanical stable. Electronic properties like the spin polarized band structure and electronic density of state, and charge density were carefully examined. The calculated band structures reveal that the analyzed materials are semiconductors ferromagnetic behavior. Moreover, a study of the magnetic properties of Sr 0.75Mn 0.25X (X = S, Se and Te) compounds indicates that the value of the total magnetic moment for each compound is approximately 5μB.

description: In questa nota si fornisce un esempio preliminare di analisi pragmatica delle strutture musicali. Nell’analisi, la stipulazione di una pragmatica musicale segue strettamente recenti proposte presentate in ambito semantico, in cui si illustrano le potenziali virtù rappresentazionali delle strutture musicali. In particolare, in questa nota si suggerisce la presenza di strategie di ricostruzione dei significati musicali le quali intervengono a prevenire la realizzazione di contenuti semantici contraddittori. L’evidenza utilizzata è ricavata da alcune misure del madrigale primo del II libro dei madrigali di Monteverdi (1590), e dal testo (di T. Tasso) che le accompagna; sviluppi dell’analisi qui proposta dovranno fondarsi su evidenze indipendenti e auspicabilmente naturali.

description: The ability of capital markets to distinguish firms of different value by size of their initial equity offerings is attenuated when insiders can sell equity more than once. A model is developed in which there is price risk from holding equity between periods. When the uncertainty is small, there must be pooling in the first period. When uncertainty is large, the pooling equilibria dominate the separating equilibrium.

description: We report on the observation of a new isomeric state in $^{68}$Ni. We suggest that the newly observed state at 168(1) keV above the first 2$^+$ state is a $π(2p-2h)$ 0$^{+}$ state across the major Z=28 shell gap. Comparison with theoretical calculations indicates a pure proton intruder configuration and the deduced low-lying structure of this key nucleus suggests a possible shape coexistence scenario involving a highly deformed state.

description: In the problem of signal detection in Gaussian white noise we show asymptotic minimaxity of kernel-based tests. The test statistics equal L2-norms of kernel estimates. The sets of alternatives are essentially nonparametric and are defined as the sets of all signals such that L2-norms of signal smoothed by the kernels exceed some constants ρε > 0. The constant ρε depends on the power ε of noise and ρε → 0 as ε → 0. Similar statements are proved also if an additional information on a signal smoothness is given. By theorems on asymptotic equivalence of statistical experiments these results are extended on the problems of testing nonparametric hypothesis on density and regression. The exact asymptotically minimax lower bounds of type II error probabilities are pointed out for all these settings. Similar results are also obtained in the problems of testing parametric hypothesis versus nonparametric sets of alternatives.
Toward a Theory of Rigidities

Publisher: name: Columbia University
Year: 1989
Subjects: Economics

description: The phenomena of dramatic variation in quantities and slight variation in prices has been a noted characteristics of business cycles. Applied to the labor market, this observation, that employment is far more variable over the cycle than wages, is one cornerstone of Keynesian theory. At the same time, real business cycle theorists accept it as a key business cycle fact to be explained. Yet attempts to provide a theoretical justification of these price rigidities have largely been unsuccessful. The article provides an explanation of this paradox based on three hypotheses; that firms act in a risk-averse manner; they are uncertain about consequences of their actions; and there is often greater uncertainty associated with pricing and wage decisions than with output and employment decisions. The first of these hypotheses is supported by ample empirical evidence; and the second, that firms are uncertain about consequences of their actions, seems uncontroversial. The third hypothesis is, however, the critical one and has been discussed in detail in the article.

description: With the large sample of young gamma-ray pulsars discovered by the Fermi Large Area Telescope (LAT), population synthesis has become a powerful tool for comparing their collective properties with model predictions. We synthesised a pulsar population based on a radio emission model and four gamma-ray gap models (Polar Cap, Slot Gap, Outer Gap, and One Pole Caustic) normalizing to the number of detected radio pulsars in select group of surveys. The luminosity and the wide beams from the outer gaps can easily account for the number of Fermi detections in 2 years of observations. The wide slot-gap beams requires an increase by a factor of ~10 of the predicted luminosity to produce a reasonable number of gamma-ray pulsars. Such large increases in the luminosity may be accommodated by implementing offset polar caps. The narrow polar-cap beams contribute at most only a handful of LAT pulsars. Standard distributions in birth location and pulsar spin-down power (Edot) fail to reproduce the LAT findings: all models under-predict the number of LAT pulsars with high Edot, and they cannot explain the high probability of detecting both the radio and gamma-ray beams at high Edot. The beaming factor remains close to 1 over 4 decades in Edot evolution for the slot gap whereas it significantly decreases with increasing age for the outer gaps. The evolution of the slot-gap luminosity with Edot is compatible with the large dispersion of gamma-ray luminosity seen in the LAT data. The stronger evolution predicted for the outer gap, which is linked to the polar cap heating by the return current, is apparently not supported by the LAT data. The LAT sample of gamma-ray pulsars therefore provides a fresh perspective on the early evolution of the luminosity and beam width of the gamma-ray emission from young pulsars, calling for thin and more luminous gaps.

description: Engineering project design, environmental impact analysis and water resources problems, particularly hydrological simulation and forecasting often require the estimation of streamflow. Simulation and forecasting techniques of streamflow time series have been applied widely for determining the dimensions of hydraulic works for risk assessment in urban water supply systems and irrigation, optimal operation of reservoir systems, optimization hydroelectric production, and so on. The present study uses two different artificial neural network (ANN) approaches for the stochastic modeling of the monthly mean streamflow of Karasu River located in the Upper Euphrates River Basin in the Eastern Anatolia part of Turkey. The ANN approaches used in this study are well known one-hidden layer feed forward back propagation (FFBP) architecture trained with the error back propagation and a variant of radial basis networks called Generalized Regression Neural Networks (GRNN). The study shows that the GRNN performs very well in the prediction of the hydrological time series. The performance of the GRNN is also found to be comparable with that of FFBP.

Fine della fine. Puccini e Turandot

description: Il presente contributo formula un’ipotesi sulle ragioni che impedirono a Puccini di portare a conclusione la sua opera Turandot. Di tali ragioni indaga le origini e il progressivo costituirsi lungo l’intero arco dell’attività creativa di Puccini. Il saggio esamina le interrelazioni fra la componente drammaturgica e la componente musicale nel finale di ciascuna opera, considerando i modi in cui gli equilibri fra le due dimensioni si evolvono da un’opera all’altra. Vengono individuate le traiettorie lungo le quali, nei lavori pucciniani, il finale d’opera, da problema formale legato a un genere specifico, si trasforma in questione linguistica. Viene mostrato come tale modulazione profonda governi la scelta dei soggetti, il taglio delle scene, la plasmazione dei personaggi, e tutti gli elementi costitutivi dello stile pucciniano. Tale dinamica viene letta come progressivo accostamento ai confini del linguaggio tonale, parte dei mutamenti linguistici che segnano l’epoca di Puccini. In questo senso, Turandot viene interpretata quale soglia linguistica.

description: This paper addresses the nature of competition in an industry in which firms experience learning-by-doing. It identifies conditions under which competition leads to an emergence of monopoly and conditions under which competition persists. Certain distinguished industrial and trade policies are then studied. The per-se doctrine is examined. Conditions are located in which the infant industry is valid. By way of contrast, it is argued that, if foreign learning is likely to be vastly superior, there may be a case for import subsidies.
Products, joins, meets, and ranges in restriction categories
Creators: name: Guo, Xiuzhan
Publisher: name: University of Calgary

description: Bibliography: p. 244-247
description: Restriction categories provide a convenient abstract formulation of partial function. However, restriction categories can have a variety of structures such as finite partial products (cartesiane s), joins, meets, and ranges which are of interest in computability theory, semigroup theory, topology, and algebraic geometry. This thesis studies these structures. For finite partial products (cartesiane ) , a construction to add finite partial product to an arbitrary restriction category freely is provided. For joins, we introduce the notion of join restriction categories, describe a construction for the join completion of a restriction category, and show the completeness of join restriction categories in partial map categories using M-adhesive categories and Mgaps. As the join completion for inverse semigroups is well-known in semigroup theory we how the relationships between the join completion for restriction categories and the join completion for inverse semigroups by providing adjunctions among restriction categories, join restriction categories, inverse categories, and join inverse categories. For meet , we introduce the notion of meet restriction categories, show the completeness of meet restriction categories in partial map categories whose M-maps include the regular monies, and provide a meet completion for restriction categories and discuss its connections with the meet completion for inverse semigroups. Finally, for ranges, Schein's representation theorem for a certain class of semigroups ( called type 3 function system) is generalized to range categories and when a partial map category satisfies Schein's condition ([RR.6]) that guarantees each map is an epimorphism onto its range is studied.
Convex relaxations of the maximin dispersion problem
Creators: name: Haines, Sheena Ayla
Publisher: name: University of British Columbia
Year: 2011

description: Recently, convex relaxations have achieved notable success in solving NP-hard optimization problems. This thesis studies semidefinite and second-order cone programming convex relaxations of the maximin dispersion problem. Providing nontrivial approximation bounds, we believe that our SDP and SOCP relaxation methods are useful in large-scale optimization. The thesis is organized as follows. We begin by recalling some basic concepts from convex analysis, nonsmooth analysis, and optimization. We then introduce the weighted maximin dispersion optimization problem; locating point(s) in a given region X ⊆ R^{n} that is/are furthest from a given set of m points. Also given are several reformulations of the original problem, including a convex relaxation problem and semidefinite and second order cone programming relaxations. Using well known results on Lipschitz functions and subdifferentials of Lipschitz functions we then derive a theoretical characterization of the optimal solutions for a given convex region X and equal weights. Next, we provide a proof that the weighted maximin dispersion problem is NP-hard even in the case where X is a box and the weights are equal. We then propose an algorithm for finding an approximate solution using the SDP relaxation, and derive an approximation bound that depends on the subset X. In the case that X is a box or a product of low-dimensional spheres, we show that the convex relaxation reduces to a second-order cone program, and provide further results on the bound provided. Lastly, we provide numerical examples using the SDP and SOCP relaxations, and suggest future work.
Sternenmomente. Karlheinz Stockhausen und die Morphologie der Zeit

description: The article tries to investigate the problem of time by following a dialectical and morphological approach derived from Goethe’s studies on nature and translated into a philosophy of time and history by Benjamin, but also from Husserl’s internal time consciousness. This research focuses especially on composers like Messiaen, Stockhausen, Xenakis and others. If Beethoven’s conception of time was teleological and monistic – just as the Hegelian one – Messiaen elaborated a dualistic and Stockhausen a pluralistic one. More in detail the research involves concepts like translation, aion and chronos, thus eternity and continuity in time or the discretional instant and the continuity of duration. Starting with the musical point of view it becomes also possible to take a look at the way, the several dimensions of time and their combinations work in other human spheres like history and policy or life and death.

A lattice-based privacy aware access control model

description: Bibliography: p. 128-132
description: Privacy is a leading concern for individuals who utilize computing resources for a variety of reasons, such as shopping online or visiting their health care provider. As service pro­viders are collecting more data from customers, it becomes more crucial to the data pro­viders how their data is treated after being collected. Hence, the fundamental part of this thesis is about data privacy. There are several ways proposed in the literature to preserve the privacy of data one of them is using access control models. Conventional access con­trol models are not suitable for privacy preserving uses and a new model should be de­signed based on the characteristics of privacy predicates. One important aspect that is not sufficiently addressed by the research community is to consider the privacy preferences of data providers as well as the practices of collectors. Hence, in the new privacy aware access control there is a mechanism to give the opportunity to the data providers to ex­press their privacy preferences about how the provided data is used.
Il concetto del tempo nella musica di Anton Webern

description: L’articolo prende in esame il concetto del “tempo” nella musica di Anton Webern, autore che ha svolto il ruolo di punto di riferimento fondamentale per le avanguardie della seconda metà del Novecento. Dalla disamina effettuata, corredata da esempi musicali, emergono due aspetti caratteristici della musica di Webern: una concezione del tempo come “durata interiore” fortemente influenzata dalla filosofia di Bergson; un’estetica musicale che si colloca, sempre per quanto concerne l’aspetto temporale, in una posizione equidistante sia dai rigidi schematismi del tempo cristallizzato e meccanizzato della tradizione tonale, sia dalla modalità immediata, “surrealista”, del puro divenire in cui lo hanno inteso le successive avanguardie. This article examines the concept of "time" in the music of Anton Webern, an author who played the role of a reference point for the avant-gardes of the second half of the Twentieth Century. From the examination carried out here, accompanied by musical examples, two characteristic aspects of Webern's music emerge: a conception of time as "inner duration" strongly influenced by Bergson's philosophy; a musical aesthetic that is placed, again with regard to the temporal aspect, in an equidistant position both from the rigid schematism of the crystallized and mechanized time of the tonal tradition, and from the immediate, “surrealist” modality (as “pure becoming”) in which the successive avant-gardes understood it.

La Configurazione del tempo nell'opera di Pierre Boulez

description: All'inizio della seconda metà del '900, il compositore, direttore d’orchestra e saggista Pierre Boulez diede avvio a una ricerca sul concetto di tempo in musica, i cui risultati devono tuttora essere adeguatamente assimilati. Tra questi, i più importanti gravitano attorno alla scoperta del tempo mobile e del tempo liscio: per loro tramite, l’artista può estendere la manipolazione del materiale tempo svolto in partitura (ad esempio sulle indicazioni dinamiche o sulle misure del battito) oltre il piano della notazione scritta. La ricerca di Boulez ha inoltre inaugurato una diversa e più precisa configurazione del tessuto temporale in musica, nella misura in cui è stata capace di includere nella struttura di un’opera sia le contingenze dell’esecuzione, che l’esperienza vissuta dell’ascoltatore. In the early 1950s, composer, conductor and essayist Pierre Boulez embarked upon an inquiry into the notion of time in music whose outcomes are yet to be thoroughly assimilated. Some of the most important results lie in the conceptualization of mobile and smooth time, which comes up with new possibilities for the artist to unfold the compositional process beyond the craftship of time signature and dynamics on the sheet alone. His research paved also the way for a different and more accurate framework of time in music itself, as it tried to outline the structure of a musical piece which includes not only the otherwise unruly happenstances of the execution, but the living experience of the listener too.

A generic execution management framework for long running jobs in grid environments
Creators: name: Elahi, Tanvire
Publisher: name: University of Calgary
Year: 2012

description: Bibliography: p. 188-202
description: Over the last decade, the grid has emerged as a paradigm of distributed and collabora­tive computing focusing on the sharing of computational and storage resources spanning across geographical and organizational domains. Greater access to high-end computa­tional facilities provides researchers fom a broad spectrum of domains an inexpensive option of carrying out sophisticated computational experiments. However, the inher­ent dynamics and heterogeneity of grid environments make the execution of resource and compute intensive applications a challenging task. Increasing fault tolerance by checkpointing and migrating jobs between resources requires significant expertise and intervention from users. Automation of such tasks can allow them to focus more on the scientific results and less on the technical details. This thesis addresses the issues associated with management of execution of long run­ning applications in grid environments. It presents a generic framework for automating execution of such applications. The framework is driven by a set of information mod­els that capture knowledge about the resources and the applications. Crucial to the functioning of the framework is information on two application characteristics: the con­figurability, and the memory usage behaviour. Separate models are presented to encode knowledge of both of these characteristics. Use of a common representation of knowledge abstracts the heterogeneity of both the resources and the applications and makes the framework functional without the need to be tailored to any specific application. Two important issues that need to be considered in managing job execution are the amount of memory required by the job and the wait time the job may experience on a specific resource. The framework presented in this thesis is equipped with mechanisms to address both of these issues. It is able to make estimations about the wait time for jobs with different resource requirements. A learning system has been designed as part of the framework to characterize the memory usage behaviour of application instances. The system facilitates execution management operations by providing accurate estimation of job's memory usage.
Examining Alternative Macroeconomic Theories

description: This paper introduces a simple variant of the new Keynesian approach to describing macroeconomic behavior that is based on informational imperfections in financial and labor markets. The basic characteristics of that model are contrasted with the characteristics of a traditional wage-rigidity based macromodel and a new classical model in which macroeconomic disturbances result from productivity shocks. The separate implications of these models are then compared to the broad empirical characteristics of business cycles in several postwar industrial economies (including the United States, United Kingdom, West Germany, Australia, and Japan) and to aspects of the prewar behavior of these economies.

description: This research concerns about the development and application of a mathematical model, based on the Saint-Venant hydrodynamic equations, to study the behavior of the propagation of a flood wave in Natural River. The model is capable of evaluating the behavior of the control variables related to the flow in terms of the hydraulic and hydrological parameters of the basin. The governing partial differential equations are solved with the aid of finite differences, and for the solution of the system of nonlinear algebraic equations the iterative Newton-Raphson algorithm is employed. A computer program QUARIGUA (Risk Quantitative Analysis of Flooding in Urban Rivers) is used to perform the simulations. To evaluate the behavior of the control variables, several scenarios for the main channel as well as for the flood waves are considered and different simulations are performed. The simulations demonstrate that roughness coefficient and bed slope of the channel play a strong game on the behavior of the flood wave propagation.

description: BACKGROUND: Health sciences librarians and nursing journal contributors have expressed concern about the impact of using strict parameters when searching the literature. PURPOSE: The purpose of this study was to explore the use of strict search criteria (eg, 5-year rule, "nurse as author") by direct care nurses and nursing students. METHODS: Fourteen online focus groups were conducted with 54 participants: direct care nurses, health sciences librarians, nursing faculty, and nursing students. Nursing faculty and health sciences librarians were included as participants to add perspective to the origins and effects of the use of stringent search criteria. RESULTS: The majority of the nurses viewed the 5-year rule and nurse as author search limits favorably, while noting that a strict date range may hamper successful searching. Librarians viewed these search criteria more unfavorably but recognized the value of topic-appropriate search limits. CONCLUSION: Reliance on strict limits can be detrimental to pertinent results; however, appropriate use is essential for relevant results. Pedagogy focused on searching the nursing literature needs to emphasize that limits are tools to be used judiciously.

description: This paper examines optimal decision making under three different organizational forms: committees, hierarchies, and polyarchies. Focus is on the trade-off between errors of rejecting good projects versus errors of accepting bad projects, and on the trade-off between gains from more extensive evaluations of projects versus costs of evaluation. The authors characterize the optimal sizes of these organizations (as well as the optimal level of consensus in committees), and then analyze how these optima change under different organizational environments. They also analyze the influence of organizational environment on the relative performance of these alternative organizational forms.

description: In this dissertation I explore environmental practices and environmental regulations in Alberta, Canada's in situ oil sands industry. The in situ oil sands industty provides an interesting context for studying these two phenomena because it was undergoing a period of high growth and subject to immense public scrutiny, particularly in regards to environmental issues. I begin by asking the question: Who does what institutional work on environmental regulations and practices in Canada's oil sands? I explore this broad research question using analytic induction, a qualitative research method that allows the researcher to explore phenomena from a pre­determined theoretical lens. In my case, this lens is institutional work. I include many different types of organizations in my san1ple of 67 semi-structured interviews. As I progress through my analysis I discover that much of the work done on practices and regulations involves boundaries. Boundary work emerges as an important aspect of institutional change, as does the type of actor doing the work and the boundary being worked on. I develop propositions based on the strength of boundaries, the position of actors in the field of in situ oil sands, and the boundary the work is done on.

description: The intrinsic pathway of apoptosis is regulated by the Bcl-2 family of proteins. Inhibition of the anti-apoptotic members represents a strategy to induce apoptotic cell death in cancer cells. We have measured the membrane binding properties of a series of peptides, including modified α/β-peptides, designed to exhibit enhanced membrane permeability to allow cell entry and improved access for engagement of Bcl-2 family members. The peptide cargo is based on the pro-apoptotic protein Bim, which interacts with all anti-apoptotic proteins to initiate apoptosis. The α/β-peptides contained cyclic β-amino acid residues designed to increase their stability and membrane permeability. Dual polarisation interferometry was used to study the binding of each peptide to two different model membrane systems designed to mimic either the plasma membrane or the outer mitochondrial membrane. The impact of each peptide on the model membrane structure was also investigated, and the results demonstrated that the modified peptides had increased affinity for the mitochondrial membrane and significantly altered the structure of the bilayer. The results also showed that the presence of an RRR motif significantly enhanced the ability of the peptides to bind to and insert into the mitochondrial membrane mimic, and provide insights into the role of selective membrane targeting of peptides.

description: Anterior cruciate ligament and meniscus tears are injuries that are known risk factors for post-traumatic OA in humans, presumably because of residual abnormal knee mechanics. This work sought to determine whether abnormal motion of the tibiofemoral joint surfaces was related to early cartilage damage in two ovine joint injury models: combined anterior cruciate and medial collateral ligament transection (ACL/MCLx), and lateral meniscectomy (Mx). Five descriptions of in vivo tibiofemoral inter-surface motion (i.e., "surface interactions") were selected based on their speculated relationship to mechanical mechanisms known to damage cartilage in vitro. The hypotheses were: H1. increasingly abnormal surface interactions would correlate with cartilage damage, H2. the number of significant correlations would be greatest in ACL/MCLx sheep, and H3. locations of cartilage damage would qualitatively coincide with. that of altered surface interactions. 21 sheep were allocated to four groups: 6 ACL/MCLx, 5 Mx, 4 sham-operated, and 6 non-operated controls. Baseline in vivo kinematics were measured prior to injury, and serially up to 20 weeks post­injury, and expressed as the difference from Intact. Cartilage damage was quantified and mapped at sacrifice. Repeated measures ANOVAs and Pearson correlation coefficients were used to determine whether surface interactions were significantly different from Intact and correlated with cartilage damage. Results partially supported the hypotheses. ACL/MCLx surface interactions were significantly abnormal, and 3/5 interactions correlated with the magnitude of cartilage damage but not its distribution. The number of significant correlations was greatest in ACL/MCLx sheep and had a cumulative effect on cartilage damage that was individual- and surface-specific, suggesting that different surface interactions may be more damaging in different individuals. Lateral compartment joint space was significantly reduced following meniscectomy, but only correlated with cartilage damage at discrete gait points for two surface interactions 20 weeks post-Mx, suggesting that surface interactions presently quantified did not reflect the primary mechanism responsible for damage in this model, likely contact stress. The presence of significant correlations between multiple surface interactions and cartilage damage in both injury models add strong support to the paradigm that altered mechanics play a pivotal role in the aetiology of early cartilage damage following these joint injuries.

description: We extend previous measurements of cosmic infrared background (CIB) fluctuations to ~ 1 deg using new data from the Spitzer Extended Deep Survey. Two fields, with depths of ~12 hr/pixel over 3 epochs, are analyzed at 3.6 and 4.5 mic. Maps of the fields were assembled using a self-calibration method uniquely suitable for probing faint diffuse backgrounds. Resolved sources were removed from the maps to a magnitude limit of AB mag ~ 25, as indicated by the level of the remaining shot noise. The maps were then Fourier-transformed and their power spectra were evaluated. Instrumental noise was estimated from the time-differenced data, and subtracting this isolates the spatial fluctuations of the actual sky. The power spectra of the source-subtracted fields remain identical (within the observational uncertainties) for the three epochs indicating that zodiacal light contributes negligibly to the fluctuations. Comparing to 8 mic power spectra shows that Galactic cirrus cannot account for the fluctuations. The signal appears isotropically distributed on the sky as required for an extragalactic origin. The CIB fluctuations continue to diverge to > 10 times those of known galaxy populations on angular scales out to < 1 deg. The low shot noise levels remaining in the diffuse maps indicate that the large scale fluctuations arise from the spatial clustering of faint sources well below the confusion noise. The spatial spectrum of these fluctuations is in reasonable agreement with an origin in populations clustered according to the standard cosmological model (LCDM) at epochs coinciding with the first stars era.
