description: We calculate the mean electromotive force in plane Couette flows of a nonrotating conducting fluid under the influence of a large-scale magnetic field for driven turbulence. A vertical stratification of the turbulence intensity results in an alpha effect owing to the presence of horizontal shear. Here we discuss the possibility of an experimental determination of the components of the alpha tensor using both quasilinear theory and nonlinear numerical simulations. For magnetic Prandtl numbers of the order of unity, we find that in the high-conductivity limit the alpha effect in the direction of the flow clearly exceeds the component in spanwise direction. In this limit, alpha runs linearly with the magnetic Reynolds number Rm while in the low-conductivity limit it runs with the product Rm*Re, where Re is the kinetic Reynolds number so that for given Rm the alpha effect grows with decreasing magnetic Prandtl number. For the small magnetic Prandtl numbers of liquid metals, a common value for the horizontal elements of the alpha tensor appears, which makes it unimportant whether the alpha effect is measured in the spanwise or streamwise directions. The resulting effect should lead to an observable voltage in both directions of about 0.5 mV for magnetic fields of 1 kgauss and velocity fluctuations of about 1 m/s in a channel of 50 cm height (independent of its width).

description: At present, 30-40 per cent of the baryons in the local Universe is still undetected. According to theoretical predictions, this gas should reside in filaments filling the large-scale structure (LSS) in the form of a Warm-Hot Intergalactic Medium (WHIM), at temperatures of 10^5 - 10^7 K, thus emitting in the soft X-ray energies via free-free interaction and line emission from heavy elements. In this work we characterize the properties of the X-ray emission of the WHIM, and the LSS in general, focusing on the influence of different physical mechanisms, namely galactic winds (GWs), black-hole feedback and star-formation, and providing estimates of possible observational constraints. To this purpose we use a set of cosmological hydrodynamical simulations that include a self-consistent treatment of star-formation and chemical enrichment of the intergalactic medium, that allows us to follow the evolution of different metal species. We construct a set of simulated light-cones to make predictions of the emission in the 0.3-10 keV energy range. We obtain that GWs increase by a factor of 2 the emission of both galaxy clusters and WHIM. The amount of oxygen at average temperature and, consequently, the amount of expected bright Ovii and Oviii lines is increased by a factor of 3 due to GWs and by 20 per cent when assuming a top-heavy IMF. We compare our results with current observational constraints and find that the emission from faint groups and WHIM should account from half to all of the unresolved X-ray background in the 1-2 keV band.

Dynamic gene expression patterns during in vivo maturation of mouse hepatoblasts
Creators: name: Lee, Sam Chi-Hang
Publisher: name: University of British Columbia
Year: 2013

description: Hepatoblasts are bipotential fetal liver cells that differentiate into hepatocytes and cholangiocytes, the parenchymal cell types in the adult liver. While genes that regulate hepatoblast differentiation have been identified, less is known about the underlying regulatory networks. Transcriptome studies using mouse whole fetal livers have been undertaken to decipher those networks. However, as 70-80% of cells in the fetal liver are hematopoietic, the resulting transcriptome data were biased toward genes expressed in blood cells and not maturing hepatoblasts. To address this, I performed a temporal transcriptome analysis using highly purified mouse fetal hepatoblasts. First, I showed that the cell surface molecule DLK1 is specifically expressed on hepatoblasts throughout fetal development. Then, fetal liver DLK1⁺ cells were isolated on embryonic days 10.5, 12.5, 14.5 and 16.5, and their respective transcriptomes were captured in Tag-seq libraries. The Tag-seq data were specifically enriched for hepatic genes, and liver-enriched transcription factors that were detected at marginal levels in previous fetal liver microarray studies were now readily observed. Furthermore, while genes associated with hepatoblast identity were consistently observed in all four DLK1⁺ libraries, cholangiocyte genes showed a gradual decrease over time, implicating DLK1 to be repressed during cholangiocyte differentiation. To identify the temporal gene expression profiles underlying hepatoblast maturation, 5449 highly expressed genes in the Tag-seq libraries were subjected to K-means clustering to generate 14 gene groups with distinct temporal expression patterns. Gene Ontology terms were differentially enriched in the gene clusters, suggesting temporally co-regulated genes to share biological functions. Further analysis was performed on HMGA2, a transcription factor with high transcript expression in early hepatoblasts. Expression of the HMGA2 protein was prominent in nascent hepatoblasts but became restricted to a small subset of hepatoblasts over time. Hmga2 mutant embryos showed a slight reduction of hepatoblasts in the fetal liver, and high Hmga2 was correlated with suppressed expression of the hepatic transcription factor HNF4A in liver cells lines. Overall, this study provides the first genome-wide, temporal analysis of the mouse hepatoblast transcriptome, and the Tag-seq libraries provide a strong foundation for understanding genetic programs that drive in vivo hepatoblast differentiation.

The heroine in modern Punjabi literature and the politics of desire
Creators: name: Dhariwal, Parvinder
Publisher: name: University of British Columbia
Year: 2013

description: This thesis project focuses on the representation of the heroine in three works of contemporary modern Punjabi literature. More specifically, I address questions regarding the importance of the heroine in literature as well as the manner in which she is portrayed. Part of the work I have done is historical in scope, as each of the heroines is constructed in accordance with the needs and perspectives of the time of her creation. I argue that the preoccupation of writers centralizing their work around women was to address the rebellion that each heroine undertakes against their subordinate position in society. However, the rebellions that occurred took place within specific historical circumstances and within larger projects within which women’s roles would be defined. The first chapter begins with Sikh reformist Bhai Vir Singh’s Sundri written in 1898. Bhai Vir Singh constructs a role model Sundri, to re-energize a sleeping community. Problematically, through this process his heroine Sundri has to sacrifice her sexuality and is transformed into a goddess whose perfection is unattainable. The second chapter analyzes a literary movement that emerges alongside the nationalist movement. Gurbaksh Singh Preetlari’s novel Anviahi Maa (Unmarried Mother) was published in 1942. The heroine of this novel is a Bengali woman named Prabha who is shunned from society for being a woman who expresses and acts on her desire. The final chapter investigates the politics of desire in Shiv Kumar Batalvi’s Loona (1965). The women in this verse play are brought to the forefront to reveal the injustices that have been committed toward them by the patriarchal society that they are trapped in. Within these three works I analyze the constructed boundaries from which these heroines cannot escape. I critique the context in which each author defends or abandons his heroine. I argue in conclusion that that there is no appropriate space in Indian society or Punjabi literature for women to present themselves as sexual beings, without being chastised.
Existence, stability and nonlinear dynamics of vortices and vortex clusters in anisotropic Bose-Einstein condensates

description: We study vortex excitations in one-component Bose-Einstein condensates, with a special emphasis on the role of anisotropic confinement for the existence, stability and dynamical properties of vortices and particularly few-vortex clusters. Symmetry breaking features are pervasive within this system even in its isotropic installment, where cascades of symmetry breaking bifurcations give rise to the multi-vortex clusters, but also within the anisotropic realm which naturally breaks the rotational symmetry of the multi-vortex states. Our first main tool for analyzing the system consists of a weakly nonlinear (bifurcation) approach which starts from the linear states of the problem and examines their continuation and bifurcation into novel symmetry-broken configurations in the nonlinear case. This is first done in the isotropic limit and the modifications introduced by the anisotropy are subsequently presented. The second main tool concerns the highly nonlinear regime where the vortices can be considered as individual topologically charged "particles" which precess within the parabolic trap and interact with each other, similarly to fluid vortices. The conclusions stemming from both the bifurcation and the interacting particle picture are corroborated by numerical computations which are also used to bridge the gap between these two opposite-end regimes.

Endogeneity in high dimensions

Year: 2012
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: Most papers on high-dimensional statistics are based on the assumption that none of the regressors are correlated with the regression error, namely, they are exogenous. Yet, endogeneity can arise incidentally from a large pool of regressors in a high-dimensional regression. This causes the inconsistency of the penalized least-squares method and possible false scientific discoveries. A necessary condition for model selection consistency of a general class of penalized regression methods is given, which allows us to prove formally the inconsistency claim. To cope with the incidental endogeneity, we construct a novel penalized focused generalized method of moments (FGMM) criterion function. The FGMM effectively achieves the dimension reduction and applies the instrumental variable methods. We show that it possesses the oracle property even in the presence of endogenous predictors, and that the solution is also near global minimum under the over-identification assumption. Finally, we also show how the semi-parametric efficiency of estimation can be achieved via a two-step approach.

Heisenberg uncertainty relation for photons

description: The idea to base the uncertainty relation for photons on the electromagnetic energy distribution in space enabled us to derive a sharp inequality that expresses the uncertainty relation [Phys. Rev. Lett. {\bf 108}, 140401 (2012)]. An alternative version of the uncertainty relation derived in this paper is closer in spirit to the original Heisenberg relation because it employs the analog of the position operator for the photon---the center of energy operator. The noncommutativity of the components of the center of energy operator results in the increase of the bound $3/2\,\hbar$ in the standard Heisenberg uncertainty relation in three dimensions. This difference diminishes with the increase of the photon energy. In the limiting case of infinite momentum frame, the lower bound in the Heisenberg uncertainty relations for photons is the same as in nonrelativistic quantum mechanics.

description: This paper considers the enumeration of ternary trees (i.e. rooted ordered trees in which each vertex has 0 or 3 children) avoiding a contiguous ternary tree pattern. We begin by finding recurrence relations for several simple tree patterns; then, for more complex trees, we compute generating functions by extending a known algorithm for pattern-avoiding binary trees. Next, we present an alternate one-dimensional notation for trees which we use to find bijections that explain why certain pairs of tree patterns yield the same avoidance generating function. Finally, we compare our bijections to known "replacement rules" for binary trees and generalize these bijections to a larger class of trees.

Una teoria della razionalità: il modello BDI
Creators: name: Larese, Costanza
Publisher: name: Rivista Italiana di Filosofia Analitica Junior
Year: 2013

description: In quest’articolo propongo un’analisi di una teoria della razionalità, il modello Belief-Desire-Intention (BDI), con l’obiettivo di stabilirne la fecondità teoretica. Interpreto il modello come il risultato dell’indebolimento di alcuni principi cardine della teoria della scelta razionale: se questa è di natura normativa e considera agenti altamente idealizzati, il modello BDI è invece motivato dallo scopo di dare una caratterizzazione cognitivamente plausibile delle azioni degli
individui e inserisce nella definizione di razionalità aspetti non normativi. Per questa ragione, la teoria BDI introduce il concetto di intenzione e complica la propria ontologia: le intenzioni pongono dei vincoli di consistenza sulla componente motivazionale dell’individuo e fungono da filtro di ammissibilità sulla selezione di altre intenzioni (Bratman, 1987). Presento ed analizzo di seguito due formalizzazioni, sviluppatesi in due diverse aree di ricerca (logica e intelligenza artificiale), dei principi filosofici della teoria: il sistema BDICTL*-W3 (Georgeff e Rao, 1998) ed un esempio di Agent Control Loop (Wooldridge, 2000). La discussione vuole rilevare le peculiarità dei vari approcci alla teoria in oggetto, individuare i nodi concettuali comuni ma anche le specificità di ciascun apporto. Concludo quindi
con alcune osservazioni di carattere epistemologico sui vantaggi di un approccio plurale.

Measurement of the transverse momentum distribution of W bosons in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

description: This paper describes a measurement of the W boson transverse momentum distribution using ATLAS pp collision data from the 2010 run of the LHC at sqrt(s) = 7 TeV, corresponding to an integrated luminosity of about 31 pb^-1. Events from both W -> e nu and W -> mu nu are used, and the transverse momentum of the W candidates is measured through the energy deposition in the calorimeter from the recoil of the W. The resulting distributions are unfolded to obtain the normalized differential cross sections as a function of the W boson transverse momentum. We present results for pTW < 300 GeV in the electron and muon channels as well as for their combination, and compare the combined results to the predictions of perturbative QCD and a selection of event generators.

description: Modern quantum theory introduces quantum structures (decompositions into subsystems) as a new discourse that is not fully comparable with the classical-physics counterpart. To this end, so-called Entanglement Relativity appears as a corollary of the universally valid quantum mechanics that can provide for a deeper and more elaborate description of the composite quantum systems. In this paper we employ this new concept to describe the hydrogen atom. We offer a consistent picture of the hydrogen atom as an open quantum system that naturally answers the following important questions: (a) how do the so called "quantum jumps" in atomic excitation and de-excitation occur? and (b) why does the classically and seemingly artificial "center-of-mass + relative degrees of freedom" structure appear as the primarily operable form in most of the experimental reality of atoms?

On-off intermittency over an extended range of control parameter

description: We propose a simple phenomenological model exhibiting on-off intermittency over an extended range of control parameter. We find that the distribution of the 'off' periods has as a power-law tail with an exponent varying continuously between -1 and -2, at odds with standard on-off intermittency which occurs at a specific value of the control parameter, and leads to the exponent -3/2. This non-trivial behavior results from the competition between a strong slowing down of the dynamics at small values of the observable, and a systematic drift toward large values.

description: We present a sample of nine high resolution cosmological simulations in the mass range of M_vir=7x10^11-4x10^12 M_sun starting from LambdaCDM initial conditions. Our simulations include primordial radiative cooling, photoionization, star formation, supernova II feedback, but exclude supernova driven winds and AGN feedback. The simulated galaxies assemble in two phases, with the initial growth dominated by compact (rr_eff) resulting in an assembly redshift of z_{f,acc}~0.5-1.5 with much larger scatter. We find a positive correlation between the fraction of accreted stars and the final mass of our galaxies. We show that gravitational feedback strongly suppresses late star formation in massive galaxies contributing to the observed galaxy color bimodality. The accretion of stellar material is also responsible for the observed size growth of early-type galaxies. In addition, we find that the dark matter fractions within the stellar half-mass radii continuously increase towards lower redshift from about f_DM~0.05 at z~3 to f_DM~0.1-0.3 at z=0. Furthermore, the logarithmic slope of the total density profile is nearly isothermal at the present-day (gamma'~1.9-2.2). Finally, the input of gravitational heating lowers the central dark matter densities in the galaxies, with the effect being smaller compared to simulations without supernova feedback.

Studies of hydrogen storage in the sodium borohydride and magnesium nickel hydride composite system
Creators: name: Afonso, Louis Greg
Publisher: name: University of British Columbia
Year: 2013

description: Complex metal hydrides typically have high enthalpies which lead to desorption temperatures that are too high for practical use. Thermodynamic destabilization is one method used to lower the enthalpy of decomposition and hence lower the temperature of desorption of a complex metal hydride. A lower temperature (less than 100ºC) would enable waste heat from a PEM(Polymer Electrolyte Membrane) fuel cell to drive the hydrogen desorption reaction. NaBH₄ was destabilized by ball milling NaBH₄ and Mg₂NiH₄ in a 4:5 molar ratio, respectively. Ball milling periods of up to 2 hours did not have an effect on the thermodynamics or the kinetics of the system. Grain sizes of the two phases, NaBH₄ and Mg₂NiH₄, were reduced during the first 30 minutes of ball milling. The decomposition enthalpy of the system was measured and found to be 67 ± 4 kJ mol⁻¹ H₂ for the decomposition of Mg₂NiH₄ in the composite, 76 ± 5 kJ mol⁻¹ for the decomposition of NaBH₄ and 95 ± 7 kJ mol⁻¹ H₂ for the decomposition of NaH, which corresponds to measured desorptions at 275, 360 and 420 ºC respectively. The enthalpy of absorption corresponding to Mg₂NiH₄ in the composite was 59 ± 4 kJ mol⁻¹ H₂ . During dehydrogenation of the NaBH₄ phase, the ternary boride phase MgNi₂.₅B₂ is formed under a hydrogen back pressure of vacuum, 1 bar and 5 bar. The total capacity of the system is 5.1 wt%, and a capacity loss of 2.25 wt% hydrogen was noted during cycling studies partially due to the formation of MgNi₂, which is a nonhydriding phase, loss of Na from the sample holder, and the formation of large crystals of Mg that could not be hydrogenated easily. Kinetic analysis was conducted and an activation energy of 131 ± 24 kJ mol⁻¹ was determined for the decomposition of the Mg₂NiH₄ phase of the composite. XRD phase analysis showed that the Mg₂NiH₄ decomposed first starting at about 275 ºC, followed by the decomposition of NaBH₄ at around 360 ºC. By 400 ºC, XRD analysis showed that the MgNi₂.₅B₂ phase had formed. The effect of cycling on the crystallographic phases showed a change from monoclinic to cubic for the Mg₂NiH₄ phase of the composite as well as the formation of MgNi₂.

description: Observations of a rare long-duration solar event of GOES class X1.2 from 26 October 2003 are presented. This event showed a pronounced burst of hard X-ray and microwave emission, which was extremely delayed (>60 min) with respect to the main impulsive phase and did not have any significant response visible in soft X-ray emission. We refer to this phenomenon as a "burst-on-tail". Based on TRACE observations of the growing flare arcade and some simplified estimation, we explain why a reaction of active region plasma to accelerated electrons may change drastically over time. We suggest that, during the "burst-on-tail", non-thermal electrons were injected into magnetic loops of larger spatial scale than during the impulsive phase bursts, thus resulting in much smaller values of plasma temperature and emission measure in their coronal volume, and hence little soft X-ray flux. The nature of the long gap between the main impulsive phase and the "burst-on-tail" is, however, still an open question.

description: The problem of separating classical from quantum correlations is in general intractable and has been solved explicitly only in few cases. In particular, known methods cannot provide general solutions for an arbitrary number of settings. We provide the complete characterization of the classical correlations and the corresponding maximal quantum violations for the case of n >= 4 observables X_0, ...,X_{n-1}, where each consecutive pair {X_i,X_{i+1}}, sum modulo n, is jointly measurable. This generalizes both the Clauser-Horne-Shimony-Holt and the Klyachko-Can-Binicioglu-Shumovsky scenarios, which are the simplest ones for, respectively, locality and noncontextuality. In addition, we provide explicit quantum states and settings with maximal quantum violation and minimal quantum dimension.

description: We study the long-time behavior of decoupled continuous-time random walks characterized by superheavy-tailed distributions of waiting times and symmetric heavy-tailed distributions of jump lengths. Our main quantity of interest is the limiting probability density of the position of the walker multiplied by a scaling function of time. We show that the probability density of the scaled walker position converges in the long-time limit to a non-degenerate one only if the scaling function behaves in a certain way. This function as well as the limiting probability density are determined in explicit form. Also, we express the limiting probability density which has heavy tails in terms of the Fox $H$-function and find its behavior for small and large distances.

description: The German economy is stuck in a period of stagnation: Following two years of consecutive slight declines in GDP, growth is not expected for 2025 either. Weak exports, rising unemployment worries, and the resulting reserved private consumption and economic policy uncertainty are slowing the economy. Structural adjustment processes and the erratic trade policy of the Trump administration are weighing on German industry. A recovery, albeit gradual, is not expected until the summer. Once a government is formed, the economic policy framework will be clearer, the labor market will stabilize, and private consumption will pick up speed a little. Further interest rate cuts by the European Central Bank should support investment. In addition, the prospective upcoming government coalition of the CDU/CSU and the SPD has agreed on a special fund for infrastructure. Without this fund, the German economy is projected to grow by 1.1 percent in 2026, and with the fund, growth is expected to be a good two percent. The global economy has largely stayed on course so far, although current US trade policy is leaving noticeable marks. Despite this, global economic output is unlikely to grow less than in 2024, with 3.5-percent growth in 2025 and 3.6-percent growth in 2026.

description: Recently, the authors have proposed a new approach to the theory of random metrics, making an explicit link between probability measures on the space of metrics on a Kahler manifold and random matrix models. We consider simple examples of such models and compute the one and two-point functions of the metric. These geometric correlation functions correspond to new interesting types of matrix model correlators. We study a large class of examples and provide in particular a detailed study of the Wishart model.

description: The price of cryptocurrency Bitcoin has risen sharply over the past ten years, with many investors adding Bitcoin to their portfolios, benefitting from price increases and diversifying their investments. But is Bitcoin suitable for this purpose? This Weekly Report examines the extent to which Bitcoin, like gold, can contribute to the diversification of an investment portfolio. To achieve this, we have calculated the correlation of monthly returns over the last ten years between U.S. and German stocks, bonds, gold, and Bitcoin. The results of our calculations indicate that, unlike gold, Bitcoin has shown a high correlation with stock market returns over time. As a result, an investment portfolio heavily weighted towards stocks cannot achieve the same level of diversification with Bitcoin as it could with gold.

Dispersion of expiratory airborne droplets in a model single patient hospital recovery room with stratified ventilation

Publisher: name: University of British Columbia
Year: 2013

description: Concerns about the environment, energy costs, and airborne infection risk have revived interest in ventilation systems for health care facilities. Low energy ventilation systems (e.g. stratified air ventilation) have received attention as a means of providing a better air quality at a lower energy cost. The sensitivity of such ventilation systems to boundary conditions in removing airborne contaminants produced by expiratory injections is of concern and studied experimentally and numerically in this work. A three step methodology is adopted. First, an air-assist internally mixing atomizer is developed to generate a poly-disperse distribution of droplets for ventilation testing. A series of near-field experiments reveal droplet size, velocity, and diffusivity in radial and axial directions for steady and transient atomization. Second, the atomizer is used to inject droplets into a mock-up of a patient recovery room with an underfloor air distribution ventilation system. A series of far-field size-resolved concentration measurements are conducted at locations representative of an occupant (receptor). Third, Computational Fluid Dynamics (CFD) simulations are used to predict airborne droplet exposure among various cases in the far-field experiments. Both tracer gas and discrete phase approaches are implemented. Based on the findings we recommend guidelines for ventilation design and room usage in real single patient hospital recovery rooms with stratified ventilation systems. It is desired to have expiratory injections at low momentum, preferably directed towards the walls or upwards. It is also advisable that occupant suspects spend most of their time away from the injection source, possibly at the corner of the room or behind the source. The variations in occupant thermal plume is not likely to affect exposure to airborne droplets in statistically significant ways. It is advisable to used air change rates greater than four since expiratory injections are likely to break down the vertical contaminant stratification. It is likely that dispersion rates be higher for sub micrometer droplets but lower for larger droplets. This has implications for ventilation design strategy as a function of pathogen or pathogen carrying droplet size.
