description: We present a study of the radial distribution of dust species in young brown dwarf disks. Our work is based on a compositional analysis of the 10 and 20 micron silicate emission features for brown dwarfs in the Taurus-Auriga star-forming region. A fundamental finding of our work is that brown dwarfs exhibit stronger signs of dust processing in the cold component of the disk, compared to the higher mass T Tauri stars in Taurus. For nearly all of our targets, we find a flat disk structure, which is consistent with the stronger signs of dust processing observed in these disks. For the case of one brown dwarf, 2M04230607, we find the forsterite mass fraction to be a factor of ~3 higher in the outer disk compared to the inner disk region. Simple large-scale radial mixing cannot account for this gradient in the dust chemical composition, and some local crystalline formation mechanism may be effective in this disk. The relatively high abundance of crystalline silicates in the outer cold regions of brown dwarf disks provides an interesting analogy to comets. In this context, we have discussed the applicability of the various mechanisms that have been proposed for comets on the formation and the outward transport of high-temperature material. We also present Chandra X-ray observations for two Taurus brown dwarfs, 2M04414825 and CFHT-BD-Tau 9. We find 2M04414825, which has a ~12% crystalline mass fraction, to be more than an order of magnitude brighter in X-ray than CFHT-BD-Tau 9, which has a ~35% crystalline mass fraction. Combining with previous X-ray data, we find the inner disk crystalline mass fractions to be anti-correlated with the X-ray strength.

description: We have analyzed an efficient integration of the multi-qubit echo quantum memory into the quantum computer scheme on the atomic resonant ensembles in quantum electrodynamics cavity. Here, one atomic ensemble with controllable inhomogeneous broadening is used for the quantum memory node and other atomic ensembles characterized by the homogeneous broadening of the resonant line are used as processing nodes. We have found optimal conditions for efficient integration of multi-qubit quantum memory modified for this analyzed physical scheme and we have determined a specified shape of the self temporal modes providing a perfect reversible transfer of the photon qubits between the quantum memory node and arbitrary processing nodes. The obtained results open the way for realization of full-scale solid state quantum computing based on using the efficient multi-qubit quantum memory.

description: This thesis reconstructs the sinking of the RoPax Ferry MV Estonia on September 28th 1994, with a strong focus on describing the chain of events that caused the eventual sinking, and how the ship sank. Once the sinking is understood, this thesis explores possible safety improvements that should be implemented in the design of new vessels of this type. The investigation is based on a combination of testimonies of survivors as well as numerical calculations based on the framework of the testimonies. Sea loads on the bow visor broke its locks and hinges. Consequently, the bow visor separated from the vessel and with it the bow ramp was ripped open because of boxlike-housing of the visor at top of the bow ramp. The loss of watertight integrity was followed by massive water ingress on the Main Car Deck and MV Estonia partially capsized to a quasi-static equilibrium floating condition. This persisted for a few minutes, whilst several side ventilation openings became immersed. From that time on, a progressive flooding started, leading to consecutively submerged windows in the superstructure failing and allowing further water ingress. Finally, at a list of about 130°, the ferry hit the sea floor stern first and the bow subsided soon after.

description: This paper theoretically and experimentally presents a first report on broadband enhanced transmission through stacked metallic multi-layers perforated with coaxial annular apertures (CAAs). Different from previous studies on extraordinary transmission that occurs at a single frequency, the enhanced transmission of our system with two or three metallic layers can span a wide frequency range with a bandwidth about 60% of the central frequency. The phenomena arise from the excitation and hybridization of guided resonance modes in CAAs among different layers. Measured transmission spectra are in good agreement with calculations semi-analytically resolved by modal expansion method.

description: This thesis explored (a) the types (cash, materials, personnel) of Canadian educational aid; .{b) the countries in Asia, Africa and Latin America to which most of this aid was given in the year 1969-1970 or the most recent 12-month period; (c) the levels (e.g., elementary, secondary, etc . ) to which most of the aid was given; {d) the socio-demographic (e.g., rural/urban) dispersion of this aid; and (e) the language problem involved in the provision of aid. The investigation was restricted to non-governmental agencies. The method employed was the mailed questionnaire and the responses indicated the following results: the distribution of materials, personnel and cash in elementary, secondary and post-secondary levels was about equal; though concentration of aid was on African and Asian countries, an increased interest was shown on Latin American countries; elementary, secondary and adult education levels received the most emphasis; elementary and secondary levels compared favourably in rural and urban areas, but post-secondary education was neglected in rural areas while aid for adult education was channelled to rural areas. Canadian agencies supported specific projects which were directly related to development such as teacher education, teaching of mathematics and science, and the training of middle level medical personnel. Analysis of the language problem indicated that colonial languages were still the official languages for the majority of the aid-receiving countries but there was a tendency to use regional and/or indigenous national languages only at the lower levels and not at the post-secondary level. Educational materials were mostly in the metropolitan languages and very few attempts at translation were indicated. Although teachers formed the largest category of educational personnel sent, very few agencies indicated having orientation programs which included language learning. With the exception of religious missions, the agencies appeared to give very little attention to language training. Data on finance indicated that educational assistance programs formed an important section of non-governmental agencies and the trend was towards greater involvement. In depth analyses of the role countries such as Canada can play in bringing about fundamental changes of structure and content of the educational systems in developing nations would be helpful to policy makers.
Physical aging in polymer and polymer nanocomposite glasses
Creators: name: Liu, Amy
Publisher: name: University of British Columbia
Year: 2010

description: Physical aging in polymer glasses is a nonequilibrium phenomenon characterized by spontaneous processes that lead to changes in almost all physical properties. While all glasses undergo physical aging, polymer glasses are among the most widely used glasses in research and engineering due to their good glass-forming properties and wide applications. This master’s thesis uses molecular dynamics (MD) simulations to explore recently observed experimental phenomena related to physical aging in polymer glasses and polymer nanocomposites. Two manuscripts (published and to be published) have been produced in the duration of this work and are included in chapters 2 and 3. The first manuscript focuses on the effect of mechanical stresses on physical aging in polymer glasses. This is a complicated and controversial subject as experimental observations have provided evidence both for and against mechanical rejuvenation and overaging. Specifically, we use MD simulations on a coarse-grained bead spring model to investigate the stress-enhanced yielding of polymer glasses. Understanding the origin of this behavior will not only verify whether this can be considered as an example of mechanically induced overaging; it will facilitate the development of more realistic constitutive relations for the yield response of glassy polymers, a subject that has been awarded considerable attention in the last few decades. The second manuscript is concerned with a relatively new area of research, which involves altering the aging behavior of polymer glasses with the addition of nanoscopic fillers. These polymer nanocomposite systems are difficult to explore due to the complicated interactions between the fillers and the polymer matrix. Unfortunately, limited experimental work (and no simulation work known to the author) have been devoted to investigating the physical aging properties of these systems. In this work, we attempt to develop a coarse-grained polymer nanocomposite MD model to study the impact of nanoparticles on the physical aging behavior of glassy polymers. This thesis should motivate the use of simulations in conjunction with experiments when studying physical aging in glasses.
title: Weitere Zunahme der sozialversicherungspflichtigen Beschäftigung ab 50 Jahren

description: Auf einen Blick...

Noch nie waren so viele Ältere ab 50 Jahren sozialversicherungspflichtig beschäftigt wie heute. Im Jahr 2010 waren 7,2 Millionen sozialversicherungspflichtig Beschäftigte bzw. über ein Viertel der sozialversicherungspflichtig Beschäftigten (26,2 Prozent) mindestens 50 Jahre alt. Das sind über eine Million Personen mehr als 2006 (5,9 Mio., 22,7 Prozent) und zwei Millionen mehr als vor gut 10 Jahren (1999: 5,2 Mio., 17,9 Prozent).
Ursachen für diese Zunahme sind das Nachrücken geburtenstarker Jahrgänge in die Altersgruppe der 50-Jährigen und Älteren und die steigende Erwerbsbeteiligung der Frauen. Zudem trägt auch ein längerer Verbleib in sozialversicherungspflichtiger Beschäftigung, also das Hinausschieben des Erwerbsaustritts, zu diesem Ergebnis bei.
Der Trend zur späteren Beendigung sozialversicherungspflichtiger Beschäftigungsverhältnisse, d.h. zu einem geringeren altersvariaten Abbau der Beschäftigtenzahlen in später geborenen im Vergleich zu früheren Kohorten, erweist sich als nahezu universell. Er ist festzustellen für beide Geschlechter, in Ost- und Westdeutschland und in allen Qualifikationsstufen.
Allerdings bestehen nach wie vor große Unterschiede zwischen Branchen. In der Öffentlichen Verwaltung werden überdurchschnittlich viele Ältere beschäftigt, im Baugewerbe und im Gastgewerbe hingegen nur wenig.
Obwohl die Zahl derjenigen, die jenseits des 60. Lebensjahres sozialversicherungspflichtig beschäftigt sind, stark gestiegen ist, geht sie auch in den derzeit jüngsten Kohorten mit jedem zusätzlichen Lebensjahr deutlich zurück. Nach wie vor wird die heutige Regelaltersgrenze von 65 Jahren nur von einer Minderheit in sozialversicherungspflichtiger Beschäftigung erreicht.

description: Der folgende Beitrag geht von der Annahme aus, dass der Wirtschaftsskandal ein zentraler Gegenstand für die soziologische Analyse der sozialen Ordnung von Märkten ist. Durch Nutzung eines praxistheoretischen Ansatzes soll die Skandalisierung von gesetzwidrigen und moralisch zweifelhaften Verhaltensweisen ökonomischer Akteure als ein Aspekt symbolischer Herrschaftsformen untersucht werden, um daraus Rückschlüsse zu ziehen, inwieweit die offenbar zunehmende öffentliche Kommunikation über Wirtschaftsskandale in den Massenmedien als Anzeichen für einen strukturellen Wandel von Herrschaft gedeutet werden kann. Hierfür wird zunächst die Bedeutung von Wirtschaftsskandalen für die soziologische Analyse der Ordnung von Märkten diskutiert (1). Danach werden bestehende wirtschaftssoziologische Ansätze für eine Erklärung von ökonomischen Skandalen und rechtswidrigen Verhaltensweisen in Unternehmen vorgestellt und in ihrer Relevanz für eine Soziologie des Wirtschaftsskandals eingeschätzt (2). Daran anschließend werden Ansatzpunkte für eine praxistheoretische Analyse von Wirtschaftsskandalen skizziert (3). Abschließend wird die Zunahme einer Skandalisierung von Management und Unternehmen unter der Fragestellung diskutiert, inwiefern die Skandalberichte über ökonomisches Fehlverhalten als Indikator für einen "Strukturwandel von Herrschaft" interpretiert werden können (4).

It generalizes and improves a method introduced in cite{MacVos97} which is based on rational Hermitean interpolation of the secular equation. Taking advantage of a further rational approximation of the secular equation which is essentially for free and which yields lower bounds of lambda_1 we obtain an improved stopping criterion.

description: PURPOSE: Failure to respond to induction chemotherapy portends a poor outcome in childhood acute lymphoblastic leukemia (ALL) and is more frequent in T-cell ALL (T-ALL) than B-cell ALL. We aimed to address the limited understanding of clinical and genetic factors that influence outcome in a cohort of patients with T-ALL induction failure (IF). METHODS: We studied all cases of T-ALL IF on two consecutive multinational randomized trials, UKALL2003 and UKALL2011, to define risk factors, treatment, and outcomes. We performed multiomic profiling to characterize the genomic landscape. RESULTS: IF occurred in 10.3% of cases and was significantly associated with increasing age, occurring in 20% of patients age 16 years and older. Five-year overall survival (OS) rates were 52.1% in IF and 90.2% in responsive patients (P < .001). Despite increased use of nelarabine-based chemotherapy consolidated by hematopoietic stem-cell transplant in UKALL2011, there was no improvement in outcome. Persistent end-of-consolidation molecular residual disease resulted in a significantly worse outcome (5-year OS, 14.3% v 68.5%; HR, 4.10; 95% CI, 1.35 to 12.45; P = .0071). Genomic profiling revealed a heterogeneous picture with 25 different initiating lesions converging on 10 subtype-defining genes. There was a remarkable abundance of TAL1 noncoding lesions, associated with a dismal outcome (5-year OS, 12.5%). Combining TAL1 lesions with mutations in the MYC and RAS pathways produces a genetic stratifier that identifies patients highly likely to fail conventional therapy (5-year OS, 23.1% v 86.4%; HR, 6.84; 95% CI, 2.78 to 16.78; P < .0001) and who should therefore be considered for experimental agents. CONCLUSION: The outcome of IF in T-ALL remains poor with current therapy. The lack of a unifying genetic driver suggests alternative approaches, particularly using immunotherapy, are urgently needed.

description: The CDF and D0 collaborations have recently reported a large forward-backward asymmetry in the ttbar system which deviates from the next to-leading order QCD standard model prediction. We study the asymmetry in the ttbar system within the framework of singlet extensions of the Minimal Supersymmetric Standard Model. For this purpose, we introduce non-renormalizable couplings between first and third generation of quarks to scalars. We analyze two limiting cases of the model, characterized by the size of the supersymmetric mass for the singlet superfield. We study both the small and large limits of this mass parameter. We find that in the region of small singlet supersymmetric mass we can obtain a large asymmetry while being consistent with limits on the ttbar production cross section. These results are also consistent with constraints arising from flavor physics, quark masses and top quark decays.

Hanging on the edge of the house: African refugees, housing, and identity in Metro Vancouver
Creators: name: Francis, Jenny
Publisher: name: University of British Columbia
Year: 2009

description: For African refugees arriving in Metro Vancouver, housing is a crucial component of settlement and integration. Given Metro Vancouver’s expensive housing market, high levels of homelessness, and consistently low vacancy rate, how are they coping in Vancouver’s housing market? What barriers do they face and what are some possible solutions? By providing an overview of the housing challenges African refugees face and identifying gaps in available services, this study expands the knowledge base upon which improved settlement policy and service provision may be built. The results show that, due to a complex combination of factors, including lack of affordable housing, discrimination, low incomes, and long application processing times, African refugees are facing a housing availability and affordability crisis in Metro Vancouver that forces them to accept substandard housing which is unsuitable, inadequate, and unaffordable. These unstable conditions are both symptomatic and generative of other problems, including poverty, debt, hunger, and a high risk of homelessness. Importantly, the study also reveals how these material conditions, which are the effect of policies grounded in theoretical perspectives around multiculturalism and notions of Canadian identity, are reflective of those underlying ideological frameworks. The author also argues that an enhanced understanding of the historical roots of current discriminatory practices is required in order to effect positive social change for the future.
Constraints from the CMB temperature and other common observational data-sets on variable dark energy density models

description: The thermodynamic and dynamical properties of a variable dark energy model with density scaling as rho_x \propto (1+z)^m, z being the redshift, are discussed following the outline of Jetzer et al. This kind of models are proven to lead to the creation/disruption of matter and radiation, which affect the cosmic evolution of both matter and radiation components in the Universe. In particular, we have concentrated on the temperature-redshift relation of radiation, which has been constrained using a very recent collection of cosmic microwave background (CMB) temperature measurements up to z ~ 3. For the first time, we have combined this observational probe with a set of independent measurements (Supernovae Ia distance moduli, CMB anisotropy, large-scale structure and observational data for the Hubble parameter), which are commonly adopted to constrain dark energy models. We find that, within the uncertainties, the model is indistinguishable from a cosmological constant which does not exchange any particles with other components. Anyway, while temperature measurements and Supernovae Ia tend to predict slightly decaying models, the contrary happens if CMB data are included. Future observations, in particular measurements of CMB temperature at large redshift, will allow to give firmer bounds on the effective equation of state parameter w_eff of this kind of dark energy models.

description: In this paper we study the enumeration and the construction, according to the number of ones, of particular binary words avoiding a fixed pattern. The growth of such words can be described by particular jumping and marked succession rules. This approach enables us to obtain an algorithm which constructs all binary words having a fixed number of ones and then kills those containing the forbidden pattern.

description: in diesem Dokument werden zwei mittlerweile vergriffene Originalbeiträge dieser Reihe aus dem Jahr 1993 wieder veröffentlicht. Inzwischen ist das Forschungsprojekt, aus dessen Kontext diese Arbeiten stammen, dokumentiert und veröffentlicht. Kernstück dieser Arbeiten ist ein arbeitspsychologisches Kooperationsmodell. Dass diese beiden Texte nicht nur eine wichtige Ergänzung und Hintergrundinformation zu diesem Modell bilden, sondern eine eigenständige Aktualität besitzen, zeigt die Tatsache, dass Gruppen und Teamkonzepte eine anhaltenden Aufschwung erleben und in der industriellen Praxis von freiwilligen Selbsthilfegruppen zur Karriereplanung (empowerment teams) bis zu einer Retaylorisierung der Gruppenfertigung in der Automobilindustrie reichen. So erinnern diese Texte auch daran, dass nicht die Tatsache der Gruppenarbeit als solche eine persönlichkeitsfördernde oder innovative Qualität besitzt, sondern der Grad an Kooperationsspielräumen, den sie eröffnet.

description: An investigation of members of the soil keratinophilic fungi community in China resulted in the identification of one new monotypic genus, Zongqia, and 10 new species, 2 of which are affiliated with Solomyces, 1 with the new genus Zongqia, 4 with Pseudogymnoascus, and 3 with Scedosporium. These novel taxa form an independent lineage distinct from other species, based on morphological and multi-loci phylogenetic analyses. Descriptions, illustrations, and notes are provided for each taxon. These new taxa of the soil keratinophilic fungi add to the increasing number of fungi known from China, and it is now evident that numerous novel taxa are awaiting to be described.

description: Monte Carlo simulations of hard-sphere (HS) crystal grown on a square patterned wall under gravity have been performed. While previous simulations were performed with step-wise controlled gravity, in the present simulations constant gravity has been applied from the first. In the case in which a flat wall is used as the bottom wall, if a large gravity is suddenly applied, the system does polycrystallize. On the other hand, in the present simulations, despite the sudden application of gravity, the system has not polycrystallize. Crystalline nucleation on the square pattern and successive crystal growth upward are suggested to overcome the homogeneous nucleation inside and result in. Defect disappearance, which has been essentially the same as that for the case with step-wise controlled gravity, has also observed for the present case. The characteristic of the square patterned bottom wall simulation with a large horizontal system size has been existence of triangular defects suggesting stacking tetrahedra.
