description: Zu den Symptomen, die Patienten mit affektiven Stoerungen zeigen, kann eine Beeintraechtigung der Kognition und der kognitiven Funktionen gehoeren. Zudem scheint es einen Zusammenhang zwischen Depression und Inflammation zu geben. Um den Einfluss des Zusammenhangs auf sozialkognitive Faehigkeiten zu untersuchen, wurden in dieser Studie Daten von 146 MDD-, 35 BD-Patienten, 67 HC ausgewertet. Die Ergebnisse weisen auf einen negativen Einfluss erhoehter IL-6-Spiegel auf die sozialkognitiven Faehigkeiten bei Patienten mit BD hin. Bei unipolar depressiven Patienten scheinen hoehere IL-1-beta-Spiegel eine positive Wirkung auf die sozialkognitiven Faehigkeiten zu haben. Somit deuten die Ergebnisse auf einen Zusammenhang zwischen Inflammation und sozial-kognitiven Faehigkeiten bei Patienten mit affektiven Stoerungen hin.

Expatriates in Papua New Guinea: constructions of expatriates in Canadian oral narratives
Creators: name: Upton, Sian Reiko
Publisher: name: University of British Columbia
Year: 2009

description: Despite social scientists' interest in globalization, mobility, the effects of colonialism, and the intercultural situations that result, little attention has been devoted to expatriates as a contemporary transnational group. This thesis is an enquiry into the ways eight individuals define themselves as expatriates, through their oral narratives of life in Papua New Guinea. The paper focuses on expatriates' characterizations of themselves in terms of: their communities; their relationships with locals; their status as foreigners in post-colonial Papua New Guinea; arid their experiences of mobility. Set against social scientific notions of expatriates and contemporary ideas of mobility and its relation to identity, expatriates' personal narratives indicate that scholarly depictions are too simplistic to access contemporary expatriates or the complex situations in which they live.

Ogni traduzione, come ogni lettura profonda, entra nella vita e nei sogni del traduttore e del lettore. Tradurre, però, a differenza di leggere, è un lavoro lungo, che oltre a richiedere tempo e fatica obbliga a restare dentro il testo fino a sentirsi mancare l’aria.

description: Context: L-type ultra-cool dwarfs and brown dwarfs have cloudy atmospheres that could host weather-like phenomena. The detection of photometric or spectral variability would provide insight into unresolved atmospheric heterogeneities, such as holes in a global cloud deck. Aims: It has been proposed that growth of heterogeneities in the global cloud deck may account for the L- to T-type transition as brown dwarf photospheres evolve from cloudy to clear conditions. Such a mechanism is compatible with variability. We searched for variability in the spectra of five L6 to T6 brown dwarfs in order to test this hypothesis. Methods: We obtained spectroscopic time series using VLT/ISAAC, over 0.99-1.13um, and IRTF/SpeX for two of our targets, in J, H and K bands. We search for statistically variable lines and correlation between those. Results: High spectral-frequency variations are seen in some objects, but these detections are marginal and need to be confirmed. We find no evidence for large amplitude variations in spectral morphology and we place firm upper limits of 2 to 3% on broad-band variability, on the time scale of a few hours. The T2 transition brown dwarf SDSS J1254-0122 shows numerous variable features, but a secure variability diagnosis would require further observations. Conclusions: Assuming that any variability arises from the rotation of patterns of large-scale clear and cloudy regions across the surface, we find that the typical physical scale of cloud cover disruption should be smaller than 5-8% of the disk area for four of our targets. The possible variations seen in SDSS J1254-0122 are not strong enough to allow us to confirm the cloud breaking hypothesis.

description: Extreme outbursts in young stars may be a common stage of pre-main-sequence stellar evolution. These outbursts, caused by enhanced accretion and accompanied by increased luminosity, can also strongly impact the evolution of the circumstellar environment. We present ALMA and VLA observations of EX Lupi, a prototypical outburst system, at 100 GHz, 45 GHz, and 15 GHz. We use these data, along with archival ALMA 232 GHz data, to fit radiative transfer models to EX Lupi's circumstellar disk in its quiescent state following the extreme outburst in 2008. The best fit models show a compact disk with a characteristic dust radius of 45 au and a total mass of 0.01 M$_{\odot}$. Our modeling suggests grain growth to sizes of at least 3 mm in the disk, possibly spurred by the recent outburst, and an ice line that has migrated inward to $0.2-0.3$ au post-outburst. At 15 GHz, we detected significant emission over the expected thermal disk emission which we attribute primarily to stellar (gyro)synchrotron and free-free disk emission. Altogether, these results highlight what may be a common impact of outbursts on the circumstellar dust.

description: We study the shape resonance effect associated with the confined transverse superconducting modes of a cylindrical nanowire in the clean limit. Results of numerical investigations of the Bogoliubov-de Gennes equations show significant deviations of the energy gap parameter from its bulk value with a profound effect on the transition temperature. The most striking is that the size of the resonances is found to be by about order of magnitude larger than in ultrathin metallic films with the same width.

description: The minuteness of the nuclear binding energy requires that mass measurements be highly precise and accurate. Here we report on new measurements $^{29-33}$Mg and $^{26}$Na performed with the {\sc Mistral} mass spectrometer at {\sc Cern}'s {\sc Isolde} facility. Since mass measurements are prone to systematic errors, considerable effort has been devoted to their evaluation and elimination in order to achieve accuracy and not only precision. We have therefore conducted a campaign of measurements for calibration and error evaluation. As a result, we now have a satisfactory description of the {\sc Mistral} calibration laws and error budget. We have applied our new understanding to previous measurements of $^{26}$Ne, $^{26-30}$Na and $^{29,32}$Mg for which re-evaluated values are reported.

description: Planck Galactic Cold Clumps (PGCCs) are contemplated to be the ideal targets to probe the early phases of star formation. We have conducted a survey of 72 young dense cores inside PGCCs in the Orion complex with the Atacama Large Millimeter/submillimeter Array (ALMA) at 1.3\,mm (band 6) using three different configurations (resolutions $\sim$ 0$\farcs$35, 1$\farcs$0, and 7$\farcs$0) to statistically investigate their evolutionary stages and sub-structures. We have obtained images of the 1.3\,mm continuum and molecular line emission ($^{12}$CO, and SiO) at an angular resolution of $\sim$ 0$\farcs$35 ($\sim$ 140\,au) with the combined arrays. We find 70 substructures within 48 detected dense cores with median dust-mass $\sim$ 0.093\,M$_{\sun}$ and deconvolved size $\sim$ 0$\farcs$27. Dense substructures are clearly detected within the central 1000\,au of four candidate prestellar cores. The sizes and masses of the substructures in continuum emission are found to be significantly reduced with protostellar evolution from Class\,0 to Class\,I. We also study the evolutionary change in the outflow characteristics through the course of protostellar mass accretion. A total of 37 sources exhibit CO outflows, and 20 ($>$50\%) show high-velocity jets in SiO. The CO velocity-extents ($Δ$Vs) span from 4 to 110 km/s with outflow cavity opening angle width at 400\,au ranging from $[Θ_{obs}]_{400}$ $\sim$ 0$\farcs$6 to 3$\farcs$9, which corresponds to 33$\fdg$4$-$125$\fdg$7. For the majority of the outflow sources, the $Δ$Vs show a positive correlation with $[Θ_{obs}]_{400}$, suggesting that as protostars undergo gravitational collapse, the cavity opening of a protostellar outflow widens and the protostars possibly generate more energetic outflows.

description: This study is on total quality management and customer satisfaction in hospitality industry in Delta State. The main objective of this study is to determine the relationship between total quality management and customer satisfaction in hospitality industry in Delta State. While the specific objectives are to: determine the relationship between customer focus and customer expectations and to ascertain the relationship between continuous improvement and service quality in hospitality industry in Delta State. The study used the descriptive survey design approach. The primary source of data was the administration of questionnaire.Quota sampling was used to select the sample of two hundred (250) respondents i.e. fifty (50) respondents each that visit the selected hotels during the period of data collection for this study.The data obtained were presented in frequency distribution tables and the corresponding values were expressed in percentages and the hypotheses developed for the study were tested using correlations analysis with the aid of statistical package for social sciences (SPSS Version 26). The results of the study revealed that there is a significant positive relationship between customer focus and customer expectations in the hospitality industry in Delta State.It also showed that there is a significant positive relationship between continuous improvement and service quality in the hospitality industry in Delta State.It was concluded thatfor the hospitality industry in Delta State to thrive, it is imperative to embrace TQM principles that focus on both customer needs and continuous service quality improvement.It was recommended among other things that hospitality businesses should regularly gather and analyze customer feedback to tailor services to meet evolving guest expectations, ensuring a customer-centric approach that boosts satisfaction and loyalty

description: Two first order strongly hyperbolic formulations of scalar-tensor theories of gravity (STT) allowing nonminimal couplings (Jordan frame) are presented along the lines of the 3+1 decomposition of spacetime. One is based on the Bona-Masso formulation while the other one employs a conformal decomposition similar to that of Baumgarte-Shapiro-Shibata-Nakamura. A modified Bona-Masso slicing condition adapted to the scalar-tensor theory is proposed for the analysis. This study confirms that the scalar-tensor theory posses a well posed Cauchy problem even when formulated in the Jordan frame.

description: Spark discharges induce a complex flow field consisting of a shock wave at early times (~ 1 $μ$ s), a pair of vortex rings, and a hot gas kernel. The vortex rings entrain ambient gas into the hot gas kernel and control its cooling and expansion. In this work, we investigate the shock wave's contribution in producing the vortex ring vorticity. We analyze high-speed (700 kHz) schlieren images of the shock wave for a range of electrical energies to measure the shock properties and estimate shock velocity and curvature. These measurements are combined with a model to calculate the vorticity generated. The measurements show that the highest vorticity is generated near the peak shock curvature location, and the shock curvature and strength increase with electrical energy deposited. A comparison of the vorticity estimated from the model to vorticity measurements from stereoscopic particle image velocimetry shows the results to be statistically equivalent. This suggests that the shock curvature and velocity contribute to the vortex rings induced by spark discharges.

Subjects: subject: Algebraic Topology (math.AT)

description: The formula is $\partial{e}=({\rm ad}_e)b+\sum_{i=0}^\infty{\frac{B_i}{i!}}({\rm ad}_e)^i(b-a)\>,$ with $\partial{a}+{1\over2}[a,a] =0$ and $\partial{b}+{1\over2}[b,b] =0$, where $a$, $b$ and $e$ in degrees $-1$, $-1$ and 0 are the free generators of a completed free graded Lie algebra $L[a,b,e]$. The coefficients are defined by ${x\over{e^x-1}}=\sum_{n=0}^\infty{B_n\over{}n!}x^n$. The theorem is that (I) this formula for $\partial$ on generators extends to a derivation of square zero on $L[a,b,e]$, (II) the formula for $\partial{e}$ is unique satisfying the first property, once given the formulae for $\partial{a}$ and $\partial{b}$, along with the condition that the "flow" generated by $e$ moves $a$ to $b$ in unit time. The immediate significance of this formula is that it computes the infinity cocommutative coalgebra structure on the chains of the closed interval. It may be derived and proved using the geometrical idea of flat connections and one parameter groups or flows of gauge transformations. The deeper significance of such general DGLAs which want to combine deformation theory and rational homotopy theory is proposed as a research problem.

description: One-dimensional systems proximity-coupled to a superconductor can be driven into a topological superconducting phase by an external magnetic field. Here, we investigate the effect of vortices created by the magnetic field in a type-II superconductor providing the proximity effect. We identify different ways in which the topological protection of Majorana modes can be compromised and discuss strategies to circumvent these detrimental effects. Our findings are also relevant to topological phases of proximitized quantum Hall edge states.

Globalisation and residential real estate in Canadian cities: a spatial approach
Creators: name: Tutchener, Judith Karen
Publisher: name: University of British Columbia
Year: 2009

description: Research on house prices and housing markets has traditionally been concerned with the modelling of house price determinants using hedonic regression equations and other methods of data interpretation. While this research has unveiled some useful insights into the relationships between housing supply, housing demand, and selling price, more recent work has focused on the "specialness" of housing as a commodity and the subsequent dismissal of regression techniques that only serve to throw us into a "statistical soup". Recent research is different in two key respects. First, forces other than macro-level variables (eg. interest rates and the availability of finance) and micro-level variables (household income, size, proximity to work) are believed to contribute to the fluctuations in housing prices over time and through space: specifically, more subjective evaluations of locational amenity, identity construction, and community are now considered in the valorisation of housing. Furthermore, newer research also understands that exogenous influences (eg. immigration, foreign investment) now play a key role in the determination of residential value. This research on residential real estate markets in Canada engages in discussions revolving around the latter of the two approaches using both qualitative and quantitative methods. At the inter-urban scale, analysis of house price movements in Canada's largest cities shows the divergence of Toronto and Vancouver from other CMAs, a trend that coincides with the increasing globalisation of both cities over the last 15 years. Further, intra-urban analyses of both Toronto and Vancouver demonstrate differential impacts of globalisation and economic restructuring within each city with particular neighbourhoods being placed on more of a "global" real estate market (eg. gentrified neighbourhoods, residential areas experiencing offshore investment, and areas of settlement for wealthy immigrants). The particular impacts of globalisation are, however, very different in each city and is dependant upon the nature of the global flows that converge there. Moreover, these results are not politically mute; considerable effort has been expended in Vancouver at least to obscure the actual effects of internationalisation on the regional housing market.

description: We present interferometric observations of the Be star 51 Ophiuchi. These observations were obtained during the science demonstration phase of the MIDI instrument at the Very Large Telescope Interferometer (VLTI). Using MIDI, a Michelson 2 beam combiner that operates at the N band (8 to 13 microns), we obtained for the first time observations of 51 Oph in the mid-infrared at high-angular resolution. It is currently known that this object presents a circumstellar dust and gas disk that shows a very different composition from other Herbig Ae disks. The nature of the 51 Oph system is still a mystery to be solved. Does it have a companion? Is it a protoplanetary system? We still don't know. Observations with MIDI at the VLTI allowed us to reach high-angular resolution (20 mas).We have several uv points that allowed us to constrain the disk model. We have modeled 51 Oph visibilities and were able to constrain the size and geometry of the 51 Oph circumstellar disk.

description: Recent studies have shown that linear electron optics can be used to generate entangled two-particle states from nonentangled ones if additional measurements of charge or parity are performed. We have investigated such nondeterministic entanglement production in electronic versions of the Mach-Zehnder interferometer, where spin-dependent interference occurs due to the presence of electric-field tunable Rashba spin splitting. Adjustment of the spin-precession length turns out to switch the entangler on and off, as well as control the detailed form of entangled output states.

description: The concept of the electron localization function (ELF) is extended to two-dimensional (2D) electron systems. We show that the topological properties of the ELF in 2D are considerably simpler than in molecules studied previously. We compute the ELF and demonstrate its usefulness for various physical 2D systems, focusing on semiconductor quantum dots that effectively correspond to a confined 2D electron gas. The ELF visualizes the shell structure of harmonic quantum dots and provides insight into electron bonding in quantum-dot molecules. In external magnetic fields the ELF is found to be a useful measure of vorticity when analyzing the properties of quantum-Hall droplets. We show that the current-dependent term in the ELF expression is important in magnetic fields.

description: We have performed sub-Doppler spectroscopy on the narrow intercombination line of cold calcium atoms using the amplified output of a femtosecond laser frequency comb. Injection locking of a 657-nm diode laser with a femtosecond comb allows for two regimes of amplification, one in which many lines of the comb are amplified, and one where a single line is predominantly amplified. The output of the laser in both regimes was used to perform kilohertz-level spectroscopy. This experiment demonstrates the potential for high-resolution absolute-frequency spectroscopy over the entire spectrum of the frequency comb output using a single high-finesse optical reference cavity.

description: This work concerns noise reduction for one-dimensional spectra in the case that the signal is corrupted by an additive white noise. The proposed method starts with mapping the noisy spectrum to a partial circulant matrix. In virtue of singular-value decomposition of the matrix, components belonging to the signal are determined by inspecting the total variations of left singular vectors. Afterwards, a smoothed spectrum is reconstructed from the low-rank approximation of the matrix consisting of the signal components only. The denoising effect of the proposed method is shown to be highly competitive among other existing nonparametric methods, including moving average, wavelet shrinkage, and total variation. Furthermore, its applicable scenarios in precision storage-ring mass spectrometry are demonstrated to be rather diverse and appealing.
title: Study of Atypical Alarmone Synthesis in Clostridioides difficile

description: Clostridioides difficile is a Gram-positive anaerobic bacterium that causes infections in humans that costs healthcare systems billions per year. C. difficile infection has high rates of recurrence due to multiple antibiotic resistance. When bacteria are in stressful environments, they produce hyperphosphorylated guanosine ribonucleotide signaling molecules called alarmones. The accumulation of alarmones activates the stringent response (SR), in which bacterial cells induce transcription of stress survival genes to delay growth and replication. The C. difficile SR is regulated by enzymatic activity of a bifunctional synthetase/hydrolase, RelA/SpoT homolog (RSH), and a monofunctional small alarmone synthetase (RelQ). Additionally, the SR is potentially regulated by a third putative synthetase (RelC) which has an uncharacterized domain. Unlike other characterized SR-utilizing bacteria, C. difficile exclusively produces a single triphosphate alarmone through atypical mechanisms despite high active site sequence homology. The first goal of this project was in silico mutational analysis of RSH and RelQ to highlight important residues potentially responsible for the unique alarmone metabolism and the second goal was to predict the functionality of RelC. Together, these aims provide the theoretical framework to identify the structural basis of unusual SR activity in C. difficile.
Test of Einstein's Mass-Energy Relation

description: The Einstein's mass-energy relation $E=mc^2$ is one of the most fundamental formulae in physics, but it has not been seriously tested by an elaborated experiment, and only some indirect evidences in nuclear reaction suggested that it holds to high precision. Manifestly, for a particle, different self potential leads to different energy-speed relation, which can be used as the fingerprints of them. In this letter, we propose an experiment to test this relation. The experiment only involves low energy of particles and measurement of speed, which can be easily realized. The experiment may shed lights on a number of fundamental puzzles in physics.

description: For the quantum affine algebra $U_q(\hat{\mathfrak{g}})$ with $\mathfrak{g}$ of classical type, let $χ_{λ/μ,a}$ be the Jacobi-Trudi type determinant for the generating series of the (supposed) $q$-characters of the fundamental representations. We conjecture that $χ_{λ/μ,a}$ is the $q$-character of a certain finite dimensional representation of $U_q(\hat{\mathfrak{g}})$. We study the tableaux description of $χ_{λ/μ,a}$ using the path method due to Gessel-Viennot. It immediately reproduces the tableau rule by Bazhanov-Reshetikhin for $A_n$ and by Kuniba-Ohta-Suzuki for $B_n$. For $C_n$, we derive the explicit tableau rule for skew diagrams $λ/μ$ of three rows and of two columns, and give the implicit tableau rule in terms of paths for general $λ/μ$.

description: We present NLO QCD results for W/Z gauge boson production with bottom quark pairs at the Tevatron including full bottom-quark mass effects. We study the impact of QCD corrections on both total cross-section and invariant mass distribution of the bottom-quark pair. Including NLO QCD corrections greatly reduces the dependence of the tree-level cross-section on the renormalization and factorization scales. We also compare our calculation to a calculation that considers massless bottom quarks and find that the bottom-quark mass effects amount to about 8-10% of the total NLO QCD cross-section and can impact the shape of the bottom-quark pair invariant mass distribution, in particular in the low invariant mass region.

description: We demonstrate using micromagnetic simulations and a theoretical model that a gradient in the saturation magnetization ($M_s$) of a perpendicularly magnetized ferromagnetic film induces a non-reciprocal spin wave propagation and, consequently an asymmetric dispersion relation. The $M_s$ gradient adds a linear potential to the spin wave equation of motion consistent with the presence of a force. We consider a transformation from an inertial reference frame in which the $M_s$ is constant to an accelerated reference frame where the resulting inertial force corresponds to the force from the $M_s$ gradient. As in the Doppler effect, the frequency shift leads to an asymmetric dispersion relation. Additionally, we show that under certain circumstances, unidirectional propagation of spin waves can be achieved which is essential for the design of magnonic circuits. Our results become more relevant in light of recent experimental works in which a suitable thermal landscape is used to dynamically modulate the saturation magnetization.

description: We consider the orthogonality graph Omega(n) with 2^n vertices corresponding to the 0-1 n-vectors, two vertices adjacent if and only if the Hamming distance between them is n/2. We show that the stability number of Omega(16) is alpha(Omega(16))= 2304, thus proving a conjecture by Galliard. The main tool we employ is a recent semidefinite programming relaxation for minimal distance binary codes due to Schrijver. As well, we give a general condition for Delsarte bound on the (co)cliques in graphs of relations of association schemes to coincide with the ratio bound, and use it to show that for Omega(n) the latter two bounds are equal to 2^n/n.

description: A new large-area Washington M,T_2+DDO51 filter survey of more than 10 deg^2 around the Carina dSph galaxy reveals a spectroscopically confirmed power law radial density "break" population of Carina giant stars extending several degrees beyond the central King profile. Magellan telescope MIKE spectroscopy establishes the existence of Carina stars to at least 4.5 times its central King limiting radius, r_lim and primarily along Carina's major axis. To keep these stars bound to the dSph would require a global Carina mass-to-light ratio of M/L > 6,300 M/L_sun. The MIKE velocities, supplemented with ~950 additional Carina field velocities from archived VLT+GIRAFFE spectra with r<=r_lim, demonstrate a nearly constant Carina velocity dispersion to just beyond r = r_lim, and both a rising velocity dispersion and a velocity shear at still larger radii. Together, the observational evidence suggests that the discovered extended Carina population represents tidal debris from the dSph. Of 65 giant candidates at large angular radii from the Carina center for which MIKE spectra have been obtained 94% are associated either with Carina or a second, newly discovered diffuse, but strongly radial velocity-coherent (velocity dispersion of 9.8 km s^-1), foreground halo system. The fifteen stars in this second, retrograde velocity population have (1) a mean metallicity ~1 dex higher than that of Carina, and (2) colors and magnitudes consistent with the red clump of the Large Magellanic Cloud (LMC). Additional spectroscopy of giant star candidates in fields linking Carina and the LMC shows a smooth velocity gradient between the LMC and the retrograde Carina moving group. We conclude that we have found Magellanic stars almost twice as far (22 deg) from the LMC center than previously known.

Molecular studies of the LysR-type regulator, mexT and its regulation of the outer membrane porin protein OprD
Creators: name: McCusker, Matthew Patrick
Publisher: name: University of British Columbia
Year: 2009

description: Pseudomonas aeruginosa OprD is a specific porin which facilitates the uptake of basic amino acids and imipenem, a carbepenem antibiotic with high potency against P.aeruginosa. Resistance to imipenem occurs frequently during antibiotic therapy of patients with P.aeruginosa infections. This study was initiated to investigate the regulatory mechanisms in P.aeruginosa for the regulation of oprD. A putative LysR-type regulator, designated mexT, was cloned on a 1.2 kb PCR fragment. DNA sequencing predicted a 304 amino acid mature MexT protein. It showed strong homology to other LysR-type regulators. When overexpressed it induced expression of the mexEF-oprN efflux operon while repressing transcription of oprD. A second line of investigation was to try and identify conditions where this mexT gene might play a role in the regulation of its target genes in P.aeruginosa. Salicylate, an aromatic weak acid known to reduce porin expression and induce low levels of multiple antibiotic resistance in other bacteria, was found to reduce expression of oprD via transcription. No change in expression of any of the efflux operons was noted. Sodium benzoate, another aromatic weak acid, was shown to reduce the levels of OprD in the outermembranes of P.aeruginosa but the mechanism of reduction was found not to via transcription. Neither iron or zinc concentrations were found effect expression of oprD or any of the efflux operons. Finally, expression of these genes during growth phase was examined. No changes were noticed.
