description: Using 2-dimensional (2D) magnetohydrodynamics (MHD) simulations, we show that Petschek-type magnetic reconnection can be induced using a simple resistivity gradient in the reconnection outflow direction, revealing the key ingredient of steady fast reconnection in the collisional limit. We find that the diffusion region self-adjusts its half-length to fit the given gradient scale of resistivity. The induced reconnection x-line and flow stagnation point always reside within the resistivity transition region closer to the higher resistivity end. The opening of one exhaust by this resistivity gradient will lead to the opening of the other exhaust located on the other side of the x-line, within the region of uniform resistivity. Potential applications of this setup to reconnection-based thrusters and solar spicules are discussed. In a separate set of numerical experiments, we explore the maximum plausible reconnection rate using a large and spatially localized resistivity right at the x-line. Interestingly, the resulting current density at the x-line drops significantly so that the normalized reconnection rate remains bounded by the value $\simeq 0.2$, consistent with the theoretical prediction.

description: The ALICE detector at CERN uses properties of the magnetic field acting on charged particles as part of the particle tracking and identification system -- via measuring the strength of bending of charged particles in a magnetic field supplied by electromagnets. During the calibration of the detector the magnetic field was measured by the scientific team. The measurement points were then fitted using Chebyshev polynomials to create a field model. That model is used extensively in particle trajectory reconstruction, but for maximum compatibility it is handled by CPU-only software. We propose multiple approaches to the implementation of the model in a shader language, which allows it to run in a graphical GPU environment. This makes the model run more efficiently, as well as enables it to be used for field visualisation, which was not previously done for ALICE.

description: In a variety of situations, isolated polymer molecules are found in a vacuum and here we examine their properties. Angular momentum conservation is shown to significantly alter the average size of a chain and its conservation is only broken slowly by thermal radiation. The time autocorrelation for monomer position oscillates with a characteristic time proportional to chain length. The oscillations and damping are analyzed in detail. Short range repulsive interactions suppress oscillations and speed up relaxation but stretched chains still show damped oscillatory time correlations.

Semiclassical limit problems with concurrent use of several clocks in quantum cosmology

description: We revisit a recent proposal for a definition of time in quantum cosmology, to investigate the effects of having more than one possible type of clock "at the same time". We use as test tube an extension of Einstein gravity with a massless scalar field in which the gravitational coupling $G_N$ is only a constant on-shell, mimicking the procedure for $Λ$ in unimodular gravity. Hence we have two "simultaneous" clocks in the theory: a scalar field clock, and the conjugate of $G_N$. We find that attempts to use two coherent clocks concurrently are disastrous for recovering the classical limit. The Heisenberg relations, instead of being saturated, are always realized abundantly above their bound, with strong quantum effects expected at least in parts of the trajectory. Semi-classical states always result from situations where we effectively impose a single clock, either by making the other clock a failed clock (i.e. by choosing a state where its conjugate constant is infinitely sharp), or by choosing a basis of constants where all clocks but one are redundant, i.e. motion or change in phase space does not occur with the passing of their "times". We show how this conclusion generalizes to fluids with any equation of state. It also applies to systems where "sub-clocks" of the same type could be used, for example in mixtures of different fluids with the same equation of state.

description: Excerpts from the report: Grazed firebreaks are open strips of improved pasture with a twofold value. First, they help to stop or slow down the spread of forest fire, provide a strip from which to backfire when making prescribed burns or attacking wildfires, and serve as access roads for deployment of men and equipment. Second, they benefit livestock and game by producing good forage during a large part of the year and by providing a means of getting increased use of native plants in the woods. This leaflet furnishes guides for establishing and maintaining grazed firebreaks. It is directed particularly to southern forest landowners interested in coordinated production of timber, cattle, and game.

description: It is the assumption of the article that films contain both ideology and utopia when they depict the actual world. The empirical case analysed is the film Sin nombre (No name, Cary Fukunaga, 2009). It represents two basic questions of the global world: a) illegal emigration from South to North, in this case from Central America through Mexico to the U.S.A. and b) the violence of youth gangs, crime and parallel culture.

description: Henri Michaux (Namur, 1899 – Paris, 1984) and Nicolas Bouvier (Geneva, 1929-1998) are two travellers who write about their experiences between the real and the imaginary Their narrative are the fruit of complex and dynamic processes that deal in first instance with memory. In this paper, I propose to analyse the metamorphosis motivated by some journeys of the writers, enhancing the difficulties, often the pain, inherent to the act of writing. Firstly, we will look into the travelling and analyse how stories come to life, in which context and with which motivations, pointing out the differences between the physical and geographical journeys and those that are more mental and imaginative. Afterwards, we will look into the threads of memory and the necessary presence of forgetfulness as survival but also as a sphere for creativity in the appropriation and transformation of time and space. Finally, we will look into the challenge and resistance of both writers to the boundaries imposed by language and memory, understanding how mental geographies look for constant deterritorialisations.

A Drinking Problem just like Grandpa’s
Creators: name: Jensen, Mikkel
Publisher: name: Akademisk kvarter | Academic Quarter
Year: 2012

description: Mikkel Jensen’s article “A Drinking Problem just like Grandpa’s” is a close reading of a single short story from Douglas Coupland’s 1994 short story cycle Life After God. The story, “Little Creatures”, portrays a gloomy drive a father takes with his child up to meet the child’s grandfather, referred to as “the golf-wino”. In this story the journey is represented as two parallel narratives of develop-ment as both the father as well as the child faces some truths either about themselves and/or the world which neither of them is ready for. Seeing how the short story chronicles a drive from an urban center through a western Canada countryside, the article comments on – with specific reference to pastoral literature – how this story marks Coupland’s departure from idealizing rural locations.

The Travails of Sal Paradise
Creators: name: Sørensen, Bent
Publisher: name: Akademisk kvarter | Academic Quarter
Year: 2012

description: The article considers one of two unresolvable paradoxes in Kerouac’s life and writing, namely his desire for constant motion while simultaneously requiring order and stability, and his desire to valorize deviance and madness positively in others, while deeply fearing it within himself. The journeys in On the Road (1957) are thus a metaphor for socially triggered psychological travails. The central observing character, Sal Paradise, is caught in a double bind. He is explicitly searching for ‘kicks’ and an elusive essence of being by traveling incessantly across the American continent, discovering its foreignness from within through encounters with eccentric yet simultaneously Sal secretly pursues a more conventional project of self-realization, namely finding the right girl to settle down with. Paradise ultimately fails on both counts in the novel, and his psy¬cho-geography can be mapped very directly onto the movements of his physical journeys.

description: We explore the transition from order to chaos for the Bohmian trajectories of a simple quantum system corresponding to the superposition of three stationary states in a 2D harmonic well with incommensurable frequencies. We study in particular the role of nodal points in the transition to chaos. Our main findings are: a) A proof of the existence of bounded domains in configuration space which are devoid of nodal points, b) An analytical construction of formal series representing regular orbits in the central domain as well as a numerical investigation of its limits of applicability. c) A detailed exploration of the phase-space structure near the nodal point. In this exploration we use an adiabatic approximation and we draw the flow chart in a moving frame of reference centered at the nodal point. We demonstrate the existence of a saddle point (called X-point) in the vicinity of the nodal point which plays a key role in the manifestation of exponential sensitivity of the orbits. One of the invariant manifolds of the X-point continues as a spiral terminating at the nodal point. We find cases of Hopf bifurcation at the nodal point and explore the associated phase space structure of the nodal point - X-point complex. We finally demonstrate the mechanism by which this complex generates chaos. Numerical examples of this mechanism are given for particular chaotic orbits, and a comparison is made with previous related works in the literature.

Heading South in Search of Female Development
Creators: name: Kim, Minjeong
Publisher: name: Akademisk kvarter | Academic Quarter
Year: 2012

description: In this essay, Minjeong Kim examines the ways in which D.H. Lawrence’s 1920 novel The Lost Girl describes its female protagonist Alvina Houghton’s journey to southern Italy. This novel introduces the motif of journey as part of the female Bildungsroman structure. Alvina travels to Pescocalascio, repudiating the patriarchal restrictions in her parochial British hometown of Woodhouse and pursuing development outside home. But the colonial fear and anxiety about what lies outside European civilization inform the narrative view of the untrod¬den southern Italian town of Pescocalascio. Where European civilization begins to fade out and sinister primitivism opens its jaw, our female protagonist becomes lost. Hence the representation of Italian primitivism in the novel frustrates Alvina’s pursuit of development, but the foreign landscape and the presence of the colonial Other within Lawrence’s text disrupt the Bildungsroman’s self-contained, teleological structure.

In the second and third parts this is the foundation of an analysis of the main characters of the novel. Ahab and Ishmael, who represent two complementary perspectives of experience of the journey as existential, subjective project. In the final part of the article it is demonstrated how the relation between these two positions of subjects form the background of both the compositional tension between plot and digression as well as the novel's genre and its enunciation.

description: The paper reports on top-down nanofabricated Ni3Si2 nanowires and tests of their electron field emission capabilities. The results include low turn on electric field, moderate work function, and the field enhancement factor, customizable through nanofabrication. The paper also reports on the issues ahead in the field of nanowires-based electron mission, as there are quantitative limitations of the applicability of the Fowler-Nordheim model, which will become increasingly apparent as we continue to optimize field emission of electrons. To this end, we suggest adding the studies of surface-to-volume ratio effects of the nanowires as another standard for comparison, in order to lead to the input form of the density of states as quantum effects becoming more prominent.

These works are part of a specific segment in art in which the displacement, the journey, and/or the walk itself assume a major role in the creative process. They are relevant because they push us to reflect on the issue of mobility at the same time that they collaborate to expand the borders in moving images.

Spectators’ Journeys

Publisher: name: Akademisk kvarter | Academic Quarter
Year: 2012

description: This articles looks at two theatrical performances from the point of view of their spectators. The act of going to the theatre is in itself a journey immediately followed by the confrontation of an unknown world during the performance. This article questions the position and roles of the spectators in contemporary, interactive performances, where spectators become central within the theatrical set-up. It analyzes two plays, Le Bardo and EUX, both presented at La Chartreuse in Villeneuve-lès-Avignon. The two plays present spectators with mixed territories of actual, fictional and virtual, and accentuate immersive processes by using virtual or augmented realities. The article argues that in those apparatus, spectators must undertake an intro-directed journey and renegotiate their own sense of being there, while remaining at the center of attention. This allows them to appropriate the territories with which they are confronted and eventually participate in the plays, in a process similar to that of the traveler.

Modeling and estimating atmospheric effects in Landsat imagery
Creators: name: Lee, Tim Kam
Publisher: name: University of British Columbia
Year: 2010

description: The values recorded by the Landsat series of sensors are influenced by local topography and atmosphere, as well as by ground cover. In order to determine the albedo at a point in the satellite image, effects due to topography and atmosphere must be removed. Topographic effects can be predicted by a reflectance map. Atmospheric effects are modeled mathematically in terms of solar irradiance, sky irradiance, path radiance and optical depth. There are six unknown parameters in the model. These are estimated with the help of a digital elevation data. Finally the albedo map is generated.

description: The song "Sirena" by Gloc-9 has become widely popular and controversial in the Philippines, especially to gays, the song's primary subject matter. This song depicts the experiences of gay individuals starting from childhood up to adulthood by portraying an image of how gays deal with their sexual preferences and how society established its perception in viewing gays. Thus, Filipino setting of a family raised conservatively and traditionally, religious affiliations, cultural norms, and family expectations are the dominating elements that influence gay individuals in dealing with their sexuality. Further, this study utilizes Interpretative Phenomenological Analysis (IPA) to describe the respondents' lived experiences, challenges, and coping mechanisms. Moreover, the implications of the study were discussed, and recommendations were suggested.

description: We extended our formulation of causal dissipative hydrodynamics [T. Koide \textit{et al.}, Phys. Rev. \textbf{C75}, 034909 (2007)] to be applicable to the ultra-relativistic regime by considering the extensiveness of irreversible currents. The new equation has a non-linear term which suppresses the effect of viscosity. We found that such a term is necessary to guarantee the positive definiteness of the inertia term and stabilize numerical calculations in ultra-relativistic initial conditions. Because of the suppression of the viscosity, the behavior of the fluid is more close to that of the ideal fluid. Our result is essentially same as that from the extended irreversible thermodynamics, but is different from the Israel-Stewart theory. A possible origin of the difference is discussed.

description: Excerpts from the report Foreword: The subject of hog cholera was closely identified with the United States Department of Agriculture from the time the former Bureau of Animal Industry was established in 1884. Indeed, it was primarily hog cholera, with its ravages to the swine industry, that indicated the need for an organization to study and control animal diseases on a national basis and led to the establishment of the Bureau of Animal Industry. This report brings under one cover the hog cholera research work of the Department of Agriculture. Originally, it was intended to be a report of the history of hog cholera research of the former Bureau of Animal Industry from its establishment in 1884 to the end of 1953, when the Bureau lost its identity in the reorganization of the Department. However, hog cholera research has been a continuing function in the Department. An account of the research activities since 1954 is included in an Addendum.
Exploring a type-theoretic approach to accessibility constraint modelling

description: The type-theoretic modelling of DRT that [degroote06] proposed features continuations for the management of the context in which a clause has to be interpreted. This approach, while keeping the standard definitions of quantifier scope, translates the rules of the accessibility constraints of discourse referents inside the semantic recipes. In this paper, we deal with additional rules for these accessibility constraints. In particular in the case of discourse referents introduced by proper nouns, that negation does not block, and in the case of rhetorical relations that structure discourses. We show how this continuation-based approach applies to those accessibility constraints and how we can consider the parallel management of various principles.

description: We report the results of an extensive set of direct numerical simulations of forced, incompressible, magnetohydrodynamic turbulence with a strong guide field. The aim is to resolve the controversy regarding the power law exponent (α, say) of the field perpendicular energy spectrum E(k_\perp) \propto k_\perp ^ α. The two main theoretical predictions, α=-3/2 and α=-5/3, have both received some support from numerical simulations carried out by different groups. Our simulations have a resolution of 512^3 mesh points, a strong guide field, an anisotropic simulation domain, and implement a broad range of large-scale forcing routines, including those previously reported in the literature. Our findings indicate that the spectrum of well developed, strong incompressible MHD turbulence with a strong guide field is E(k_{\perp})\propto k_{\perp}^{-3/2}.

description: Abridged abstract: The Red MSX Source (RMS) survey is an ongoing effort to return a large, well-selected sample of massive young stellar objects (MYSOs) within our Galaxy. A series of ground-based follow-up observations are being undertaken in order to remove contaminant objects from our list of 2000 candidates, and to begin characterising these MYSOs. As a part of these follow-up observations, high resolution (~1") mid-IR imaging aids the identification of contaminant objects which are resolved (UCHII regions, PN) as opposed to those which are unresolved (YSOs, evolved stars) as well as identifying YSOs near UCHII regions and other multiple sources. We present 10.4 micron imaging observations for 346 candidate MYSOs in the RMS survey in the Southern Hemisphere, primarily outside the region covered by the GLIMPSE Spitzer Legacy Survey. These were obtained using TIMMI2 on the ESO 3.6m telescope in La Silla, Chile. Our photometric accuracy is of order 0.05Jy, and our astrometric accuracy is 0.8", which is an improvement over the nominal 2" accuracy of the MSX PSC.

description: We present an update of 3C 273's database hosted by the ISDC, completed with data from radio to gamma-ray observations over the last 10 years. We use this large data set to study the multiwavelength properties of this quasar,especially focussing on its variability behaviour. We study the amplitude of the variations and the maximum variability time scales across the broad-band spectrum and correlate the light curves in different bands, specifically with the X-rays, to search for possible connections between the emission at different energies. 3C 273 shows variability at all frequencies, with amplitudes and time scales strongly depending on the energy and being the signatures of the different emission mechanisms. The variability properties of the X-ray band imply the presence of either two separate components (possibly a Seyfert-like and a blazar-like) or at least two parameters with distinct timing properties to account for the X-ray emission below and above ~20 keV. The dominant hard X-ray emission is most probably not due to electrons accelerated by the shock waves in the jet as their variability does not correlate with the flaring millimeter emission, but seems to be associated to long-timescale variations in the optical. This optical component is consistent with being optically thin synchrotron radiation from the base of the jet and the hard X-rays would be produced through inverse Compton processes (SSC and/or EC) by the same electron population. We show evidence that this synchrotron component extends from the optical to the near-infrared domain, where it is blended by emission of heated dust that we find to be located within about 1 light-year from the ultraviolet source.

description: We study the effects of dissipation on electron transport in a semiconductor superlattice with an applied bias voltage and a magnetic field that is tilted relative to the superlattice axis.In previous work, we showed that although the applied fields are stationary,they act like a THz plane wave, which strongly couples the Bloch and cyclotron motion of electrons within the lowest miniband. As a consequence,the electrons exhibit a unique type of Hamiltonian chaos, which creates an intricate mesh of conduction channels (a stochastic web) in phase space, leading to a large resonant increase in the current flow at critical values of the applied voltage. This phase-space patterning provides a sensitive mechanism for controlling electrical resistance. In this paper, we investigate the effects of dissipation on the electron dynamics by modifying the semiclassical equations of motion to include a linear damping term. We demonstrate that even in the presence of dissipation,deterministic chaos plays an important role in the electron transport process. We identify mechanisms for the onset of chaos and explore the associated sequence of bifurcations in the electron trajectories. When the Bloch and cyclotron frequencies are commensurate, complex multistability phenomena occur in the system. In particular, for fixed values of the control parameters several distinct stable regimes can coexist, each corresponding to different initial conditions. We show that this multistability has clear, experimentally-observable, signatures in the electron transport characteristics.

description: The enormous amount of code required to design modern hardware implementations often leads to critical vulnerabilities being overlooked. Especially vulnerabilities that compromise the confidentiality of sensitive data, such as cryptographic keys, have a major impact on the trustworthiness of an entire system. Information flow analysis can elaborate whether information from sensitive signals flows towards outputs or untrusted components of the system. But most of these analytical strategies rely on the non-interference property, stating that the untrusted targets must not be influenced by the source's data, which is shown to be too inflexible for many applications. To address this issue, there are approaches to quantify the information flow between components such that insignificant leakage can be neglected. Due to the high computational complexity of this quantification, approximations are needed, which introduce mispredictions. To tackle those limitations, we reformulate the approximations. Further, we propose a tool QFlow with a higher detection rate than previous tools. It can be used by non-experienced users to identify data leakages in hardware designs, thus facilitating a security-aware design process.

description: We consider the quasinormal spectrum of a charged scalar field in the (charged) Reissner-Nordstrom spacetime, which has two horizons. The spectrum is characterized by two distinct families of asymptotic resonances. We suggest and demonstrate the according to Bohr's correspondence principle and in agreement with the Bekenstein-Mukhanov quantization scheme, one of these resonances corresponds to a fundamental change of Delta A=4hbar ln2 in the surface area of the black-hole outer horizon. The second asymptotic resonance is associated with a fundamental change of Delta Atot=4hbar ln3 in the total area of the black hole (in the sum of the surface areas of the inner and outer horizons), in accordance with a suggestion of Makela and Repo.

description: The results of dc and ac magnetization, electrical resistance and heat capacity studies in an admixed rare earth alloy Nd0.75Gd0.25Rh3B2, which is close to the zero magnetization limit, are reported. Novel observations include the two antiferromagnetic like transitions, concomitant repeated/multiple magnetic compensation behaviour and a characteristic oscillatory magnetic response, with temperature dependence of magnetization at low fields crossing the M = 0 axis thrice. The effective coercive field relating to the residual remanence also has an oscillatory response, with two minima located close to two zero-crossover temperatures. The unusual behavior in Nd0.75Gd0.25Rh3B2 is conjectured to arise from its anisotropic hexagonal structure, with planar anisotropy, resulting in a quasi one dimensional electronic structure and the accentuated role of conduction electron polarization near the zero magnetization limit.

description: We derive the form of the infrared gluon propagator by proving a mapping in the infrared of the quantum Yang-Mills and $λϕ^4$ theories. The equivalence is complete at a classical level. But while at a quantum level, the correspondence is spoiled by quantum fluctuations in the ultraviolet limit, we prove that it holds in the infrared where the coupling constant happens to be very large. The infrared propagator is then obtained from the quantum field theory of the scalar field producing a full spectrum. The results are in fully agreement with recent lattice computations. We get a finite propagator at zero momentum, the ghost propagator going to infinity as $1/p^{2+2κ}$ with $κ=0$.

description: We investigate a two-parameter entropy introduced by Schwämmle and Tsallis and obtain its probability distribution in the canonical ensemble. The probability distribution is given in terms of the Lambert W-function which has been used in many branches of physics, especially in fractal structures. Also, extensivity of $S_{q,q'}$ is discussed and a relationship is found to exist between the probabilities of a composite system and its subsystems so that the two-parameter entropy, $S_{q,q'}$, is extensive.

Designing a portable natural language database interface
Creators: name: Booth, Allan David
Publisher: name: University of British Columbia
Year: 2010

description: Allowing a user to inquire into a database in his native language is becoming an increasingly desirable feature. Consequently, there have been a number of attempts to attach a natural language front end to an existing database management system. However, few database systems today are competent in processing natural language queries. The main stumbling block is the adaptation of an existing natural language front end to a new domain of discourse. The development of a domain independent natural language interface to an existing database management system is discussed here. The underlying domain independent features of natural language are examined and combined into one linguistic core. The domain specific information is gathered into an information dictionary for the linguistic core to process. Finally, the interface to the database handling routines is modularized with standard inputs and outputs.
