description: We study a two-species bosonic Hubbard model on a two-dimensional square lattice by means of quantum Monte Carlo simulations. In addition to the usual contact repulsive interactions between the particles, the Hamiltonian has an interconversion term which allows the transformation of two particles from one species to the other. The phases are characterized by their solid or superfluid properties and by their polarization, i.e. the difference in the populations. When inter-species interactions are smaller than the intra-species ones, the system is unpolarized, whereas in the opposite case the system is unpolarized in even Mott insulator lobes and polarized in odd Mott lobes and also in the superfluid phase. We show that in the latter case the transition between the Mott insulator of total density two and the superfluid can be either of second or first order depending on the relative values of the interactions, whereas the transitions are continuous in all other cases.

description: In this work, the hydraulic process of preparing the wort is accepted for consideration.
The first chapter provides a detailed analysis of the entire technological process. A technique for constructing a hydraulic system model is considered and a transition algorithm is created. The second chapter discusses a thorough transition from the hydraulic system to electrical analogues for each stage, based on the electro-hydraulic analogy method. In the third chapter, mathematical models for all stages interacting with each other are developed and modeled. Studied the simulink embedded software package, the analysis of the interaction of processes. The resulting electrical circuits allow you to clearly demonstrate and analyze the results of hydraulic processes.

description: Operation of semiconductor scintillators requires optically-tight integration of the photoreceiver system on the surface of the scintillator slab. We have implemented an efficient and fast quaternary InGaAsP pin photodiode, epitaxially grown upon the surface of an InP scintillator wafer and sensitive to InP luminescence. The diode is characterized by an extremely low room-temperature dark current, about 1 nA/cm2 at the reverse bias of 2 V. The low leakage makes possible a sensitive readout circuitry even though the diode has a large area (1 mm/times1 mm) and therefore large capacitance (50 pF). Results of electrical, optical and radiation testing of the diodes are presented. Detection of individual α-particles and γ-photons is demonstrated.

description: The Press-Ryden-Spergel (PRS) algorithm is a modification to the field theory equations of motion, parametrized by two parameters ($α$ and $β$), implemented in numerical simulations of cosmological domain wall networks, in order to ensure a fixed comoving resolution. In this paper we explicitly demonstrate that the PRS algorithm provides the correct domain wall dynamics in $N+1$-dimensional Friedmann-Robertson-Walker (FRW) universes if $α+β/2=N$, fully validating its use in numerical studies of cosmic domain evolution. We further show that this result is valid for generic thin featureless domain walls, independently of the Lagrangian of the model.

description: Background. We examined whether a high-dose inactivated influenza vaccine was more efficacious in preventing hospitalizations than a standard-dose vaccine in the Veterans Health Administration (VHA) senior population. Methods. This study estimated the relative vaccine effectiveness (rVE) of high dose versus standard dose using a retrospective cohort of VHA patients 65 years of age or older in the 2015–2016 influenza season. To adjust for measured confounders, we matched each high-dose recipient with up to 4 standard-dose recipients vaccinated at the same location within a 2-week period and having 2 or more pre-existing medical comorbidities. We used the previous event rate ratio method (PERR), a type of difference-in-differences analysis, to adjust for unmeasured confounders. Results. We evaluated 104 965 standard-dose and 125 776 high-dose recipients; matching decreased the population to 49 091 standard-dose and 24 682 high-dose recipients. The matched, PERR-adjusted rVE was 25% (95% confidence interval [CI], 2%–43%) against influenza- or pneumonia-associated hospitalization, 7% (95% CI, −2% to 14%) against all-cause hospitalization, 14% (95% CI, −8% to 32%) against influenza- or pneumonia-associated outpatient visit, 5% (95% CI, 2%–8%) against all-cause outpatient visit, and 38% (95% CI, −5% to 65%) against laboratory-confirmed influenza. Conclusions. In protecting senior VHA patients against influenza- or pneumonia-associated hospitalization, a high-dose influenza vaccine is more effective than a standard-dose vaccine.

description: Using neutron reflectivity together with an appropriate electrochemical cell, we have studied the effects of transverse electric field on the Bovine Serum Albumin (BSA) monolayer initially adsorbed at the interface of the aqueous solution and a conductive doped-silicon wafer. Depending on the sign of the initial potential, a second layer is adsorbed on top of the first whereas a subsequent reversal of potential has no effect. We show that this behavior reveals the slow and remanent electric polarization of the first BSA layer and suggest an analogy with spin glasses based on the dipolar structure of this protein.

description: Un bambino che si accinge a scrivere un testo fa capo al processo di interconnessione tra le parole secondo cui, da una parola, possono generarsene delle altre. Fra gli strumenti per facilitare questo processo vi sono le rime che possono essere associate ad altri elementi tipici della filastrocca, tra i quali, la struttura di tipo binario e la scansione ritmica facilmente assimilabile. Attraverso questa ricerca azione, svolta all’interno di una terza elementare, si vuole provare a comprendere se sia possibile favorire la scrittura di brevi testi in rima grazie al supporto di una struttura ritmica musicale. Come strumenti per questa sperimentazione sono state utilizzate delle autovalutazioni per gli allievi e delle tabelle osservative, grazie alle quali è stato possibile raccogliere una parte dei dati per la stesura di alcune ipotesi. A causa della situazione sanitaria venutasi a creare, dovuta al virus COVID19 e la conseguente chiusura delle scuole, questa ricerca non è stata portata a termine. Relatore: Matteo Piricò.
Solar fuel generation by graphitic carbon nitride composites
Creators: name: Lachance, Robert
Publisher: name: University of British Columbia
Year: 2020

description: Solar fuels are an attractive medium for long term storage of solar energy, but the low efficiency of photocatalysts in visible light prevents large scale adoption. Graphitic carbon nitride (g-CN) is a promising photocatalyst for solar fuel generation with a medium bandgap and demonstrated ability for photocatalyst engineering to improve charge recombination and charge mobility. In this work the improvement of g-CN material is investigated via phosphorous doping and post synthesis techniques to stabilize the g-CN surface chemistry and prepare the material for heterojunction integration. Further, the improved visible light absorption and activity of a self- assembled 2D-2D precious metal free g-CN type II heterojunction z-scheme is presented, targeting photocatalytic CO2 reduction and hydrogen evolution for solar fuel applications. The synergistic combination of highly reducing electrons in the conduction band of g-CN and very oxidizing holes in the valence band of BiVO4 enables tunable, small bandgap, visible light active materials to perform artificial photosynthesis. Strong interfacial ohmic contact induced by the electrostatic attraction of z-scheme constituent materials to promote charge separation is investigated with the addition of reduced graphene oxide (rGO) acting as an electron transfer medium. A realistic flat plate circulating batch reactor operating in the vapor phase, illuminated by a Xe arc solar simulator and coupled with online gas chromatography is employed for the evaluation of photocatalyst materials. This z-scheme employs facile synthesis techniques to achieve a visible light active, tunable band edge constituent material with similar reaction overpotentials to iii single, UV active materials such as TiO₂. Photoreduction of CO₂ improves over 100% and water splitting improves nearly 40% for the g-CN/BiVO₄ composite and is attributed to strong interfacial z-scheme charge transfer. Protonation and phosphorous doping are shown to influence the amount and oxidation state of the amine functional groups present on the g-CN surface, with protonation demonstrating nearly 4X increase in CO₂ reduction compared to washed g-CN and attributed to increased CO₂ adsorption. The work presented provides a pathway to electrostatic self-assembly of 2D-2D z-scheme heterojunctions for improved photocatalytic solar fuel generation.
Measuring Dynamical K/$π$ and p/$π$ Fluctuations in Au+Au Collisions from the STAR Experiment
Creators: name: Tarnowsky, Terence
Publisher: name: arXiv
Year: 2011
Subjects: subject: Nuclear Experiment (nucl-ex)

description: Results from new measurements of dynamical $K/π$ and $p/π$ ratio fluctuations are presented. Dynamical fluctuations in global conserved quantities such as baryon number, strangeness, or charge may be observed near a QCD critical point. The STAR experiment has previously acquired data in Au+Au collisions at the energies $\sqrt{s_{NN}}$ = 200, 130, 62.4, and 19.6 GeV and Cu+Cu collisions at $\sqrt{s_{NN}}$ = 200, 62.4, and 22.4 GeV. The commencing of a QCD critical point search at RHIC has extended the reach of possible measurements of dynamical $K/π$ and $p/π$ ratio fluctuations from Au+Au collisions to lower energies. New results are compared to previous measurements and to theoretical predictions from the UrQMD model.

description: One of the primary goals of the Large Hadron Collider is to understand the electroweak symmetry breaking mechanism. In the Standard Model, electroweak symmetry breaking is described by the Higgs mechanism which includes a scalar Higgs boson. Electroweak measurements constrain the Standard Model Higgs boson mass to be in the 114.4 to 157 GeV/c^2 range. Within this mass window, the Higgs predominantly decays into two b-quarks. As such, we investigate the prospect of observing the Standard Model Higgs decaying to b\bar{b} produced in weak-boson-fusion with an associated central photon. An isolated, high pt, central photon trigger is expected to be available at the ATLAS and CMS experiments. In this study, we investigated the effects originating from showering, hadronization, the underlying event model, and jet performance including b-jet calibration on the sensitivity of this channel. We found that the choice of Monte Carlo and Monte Carlo tune has a large effect on the efficacy of the central jet veto and consequently the signal significance. A signal significance of about 1.86 can be achieved for m(Higgs)=115 GeV/c^2 with 100 1/fb of integrated luminosity which correspond to one year at design luminosity at 14 TeV pp collisions.

description: Il tema di questa ricerca concerne l’avvicinamento spontaneo dei bambini di Scuola dell’Infanzia al codice della lingua scritta. In particolare, l’interrogativo è quello di verificare se, e in quale misura, l’introduzione di uno spazio specificatamente dedicato al contatto con la scrittura, come il “Laboratorio della posta”, in questo ordine scolastico, può favorire l’evoluzione delle concezioni circa la funzionalità del linguaggio scritto e del livello di concettualizzazione dello stesso. La ricerca si è basata sulla somministrazione di un’intervista volta a indagare le rappresentazioni della lingua scritta di un gruppo campione di bambini, e sulla raccolta e l’analisi delle loro produzioni scritte prima e dopo la sperimentazione. Al fine di ottenere un ulteriore riscontro sui dati raccolti, la stessa intervista è stata condotta anche con un gruppo di controllo. Per quanto riguarda l’intervista, si è registrata un’evoluzione delle rappresentazioni della lingua scritta per il gruppo campione. L’analisi delle produzioni, invece, ha mostrato tratti di evoluzione a livello qualitativo. Tale ricerca ha contribuito a mostrare che i bambini, ben prima dell’entrata nella scuola elementare, possiedono delle personali concezioni sul linguaggio scritto. Compito di una docente di Scuola dell’Infanzia è quello di creare delle situazioni volte a incentivare l’interesse spontaneo di tutti i bambini nei confronti del codice scritto, partendo proprio dalle loro concezioni e favorendone lo sviluppo.

Using the two-state Landau-Zener model for illustrative simulations of a controlled qubit, we generate optimal controls for π/2- and π-pulses, and investigate their inherent robustness to uncertainty in the magnitude of the drift Hamiltonian. Next, we construct a quantum-control protocol to improve system-drift robustness by combining environment-decoupling pulse criteria and optimal control theory for unitary operations. By perturbatively expanding the unitary time-evolution operator for an open quantum system, previous analysis of environment-decoupling control pulses has calculated explicit control-field criteria to suppress environment-induced errors up to (but not including) third order from π/2- and π-pulses. We systematically integrate this criteria with optimal control theory, incorporating an estimate of the uncertain parameter, to produce improvements in gate fidelity and robustness, demonstrated via a numerical example based on double quantum dot qubits. For the qubit model used in this work, post facto analysis of the resulting controls suggests that realistic control-field fluctuations and noise may contribute just as significantly to gate errors as system and environment fluctuations.

description: Epidemiology is maturing as a discipline, with increasingly standardized approaches to how we design studies to answer questions of scientific, clinical, and public health interest. Over time, the repertoire changes, and it is likely to continue to evolve for both technological and methodological reasons. With regard to the former, approaches change because of both the phase-out of older technologies (such as a move away from telephone surveys as patterns of phone coverage and usage shifted) and the introduction of new technologies (such as the utilization of novel environmental data through satellite mapping or of the rapidly evolving ways of collecting real-time assessment of exposure and health status from smart phone users). The latter category includes both methodological innovations (such as increased reliance on nested studies) and the recognition of methodological flaws in older methods (such as the gradual abandonment of hospital-based case-control studies).

description: Eta bound states in nuclei are sensitive to the flavour-singlet component in the eta. The bigger the singlet component, the more attraction and the greater the binding. eta-etaprime mixing plays an important role in understanding the value of the eta-nucleon scattering length a_{ηN}. Working with the Quark Meson Coupling model, we find a factor of two enhancement from mixing relative to the prediction with a pure octet eta.

Angular momentum transport by thermal emission in black hole accretion disks

Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: We calculate the amount of angular momentum that thermal photons carry out of a viscous black hole accretion disc, due to the strong Doppler shift imparted to them by the high orbital velocity of the radiating disc material. While the emission of radiation can not drive accretion on its own, we find that it does result in a loss of specific angular momentum, thereby contributing to an otherwise viscosity-driven accretion flow. In particular, we show that the fraction of the angular momentum that is lost to thermal emission at a radius r in a standard, multi-color disc is ~ 0.4r_s/r, where r_s is the Schwarzschild radius of the black hole. We briefly highlight the key similarities between this effect and the closely related Poynting-Robertson effect.

description: Under certain circumstances, the time behavior of a random walk is modulated by logarithmic periodic oscillations. The goal of this paper is to present a simple and pedagogical explanation of the origin of this modulation for diffusion on a substrate with two properties: self-similarity and finite ramification order. On these media, the time dependence of the mean-square displacement shows log-periodic modulations around a leading power law, which can be understood on the base of a hierarchical set of diffusion constants. Both the random walk exponent and the period of oscillations are analytically obtained for a pair of examples, one fractal, the other non-fractal, and confirmed by Monte Carlo simulations.

description: Large volume metrology is a key enabler of autonomous precision manufacturing. For component positioning, the optical-based metrology technique of photogrammetry could be used more widely if its accuracy was improved. These positional measurements are subject to uncertainties which can be greater than manufacturing tolerances. One source of uncertainty is due to thermal gradients, which cause the refraction of the light rays in large-scale industrial environments. This paper uses light-based sensor data to reconstruct a heterogeneous spatial map of the refractive index in air. We use this reconstructed refractive index map to discount the refractive effects and thereby reduce the uncertainty of this positioning problem. This new inverse problem employs Voronoi tessellations to spatially parameterize the refractive index map, the Fast Marching Method to solve the forward problem of calculating the light rays through this medium, and a Bayesian approach in the inversion. Using simulated data, this methodology leads to positioning improvements of up to 37%.

Discovery of a Planetary-mass Companion to a Brown Dwarf in Taurus

description: We have performed a survey for substellar companions to young brown dwarfs in the Taurus star-forming region using the Wide Field Planetary Camera 2 on board the Hubble Space Telescope. In these data, we have discovered a candidate companion at a projected separation of 0.105" from one of the brown dwarfs, corresponding to 15 AU at the distance of Taurus. To determine if this object is a companion, we have obtained images of the pair at a second epoch with the adaptive optics system at Gemini Observatory. The astrometry from the Hubble and Gemini data indicates that the two objects share similar proper motions and thus are likely companions. We estimate a mass of 5-10 Mjup for the secondary based on a comparison of its bolometric luminosity to the predictions of theoretical evolutionary models. This object demonstrates that planetary-mass companions to brown dwarfs can form on a timescale of <=1 Myr. Companion formation on such a rapid timescale is more likely to occur via gravitational instability in a disk or fragmentation of a cloud core than through core accretion. The Gemini images also reveal a possible substellar companion (rho=0.23") to a young low-mass star that is 12.4" from the brown dwarf targeted by Hubble. If these four objects comprise a quadruple system, then its hierarchical configuration would suggest that the fragmentation of molecular cloud cores can produce companions below 10 Mjup.

title: Katalysator- und Prozessentwicklung für die Umwandlung von CO₂ zu Diethylcarbonat
Creators: name: Buchmann, Marco
Publisher: name: UNSPECIFIED
Year: 2022

description: Der fortschreitende Klimawandel, verändertes Umweltbewusstsein und sich verringernde Kohle-, Öl- und Gasvorräte machen die Erschließung neuer Rohstoffquellen nötig. CO₂ kommt hier eine besondere Rolle zu, da es sowohl für einen Großteil des Klimawandels verantwortlich ist als auch eine Kohlenstoffquelle mit weltweiter Verfügbarkeit darstellt. In einem ersten Schritt konnte ein Ceroxidkatalysator entwickelt werden, der eine gute Performance in der Diethylcarbonatsynthese zeigt. Hierbei ist eine pH-Wert- und temperaturgesteuerte Katalysatorfällung, als auch die Beachtung thermodynamischer Limitierungen in der Carbonatsynthese notwendig. Die größte Herausforderung in der Diethylcarbonatsynthese stellt dabei die Gleichgewichtslimitierung auf Seite der Edukte dar. Einzig die Entfernung von Wasser aus dem Gleichgewicht erweist sich als zweckmäßig. Zum Einsatz kommen hier organische und anorganische Membranen, welche jedoch nicht langzeitstabil gegenüber CO₂ sind, sodass ein erfolgreicher Verfahrensansatz nicht weiterverfolgt werden kann. Zur Erweiterung des potentiellen Produktspektrums in der Verwendung von Diethylcarbonat als Brückenmolekül in der CO₂-Nutzung wird die Hydrierung zu Methanol untersucht. Erste Versuchsreihen weisen eine gute Ausbeute bei der Verwendung von kombinierten Kupfer-Ceroxidkatalysatoren auf. Hier kann in einer weiterführenden Arbeit eine direkte Hydrierung/Carboxylierung untersucht werden, was entscheidende Vorteile und Vereinfachungen im verfahrenstechnischen Sinne mit sich bringen kann.
Energy, entropy, and spacetime : lessons from semiclassical black holes
Creators: name: Costa, Bruno Arderucio
Publisher: name: University of British Columbia
Year: 2020

description: This doctoral thesis explores semiclassical effects on black hole physics. Semiclassical theory refers to the application of quantum field theory in curved, classical background geometries, which respond to the expectation value of the regularised stress-energy tensor of the quantum matter. Among the original findings, I develop a few useful techniques to help regularise the stress-energy tensor in two dimensions. I apply them to a model of stellar collapse to analyse the importance of quantum mechanical effects in the collapse itself. I find an explicit example showing that the behaviour of the late-time Hawking radiation does not depend on the details of the collapse and argue that any quantum mechanical effect is negligible for the collapse of an astrophysical object (whose mass is comparable to the solar mass). In the realm of black hole thermodynamics, I prove the first law for stationary black holes and propose a definition for the entropy in piecewise stationary black holes which I show to obey the generalised second law of thermodynamics. After also discussing the zeroth law, it becomes clear that this set of laws is rooted in semiclassical physics and give the hypotheses which are necessary for it to hold. My derivation of the laws of black hole thermodynamics also contributes towards the answer to the long-standing question of interpreting the Bekenstein-Hawking entropy. My work suggests that it is understood from the information perspective as accounting for the information hidden behind the horizon.

description: We obtain, via the formalism of tensor actions, a complete classification of the localizing subcategories of the stable derived category of any affine scheme with hypersurface singularities and of any local complete intersection over a field; in particular this classifies the thick subcategories of the singularity categories of such rings. The analogous result is also proved for certain locally complete intersection schemes. It is also shown that from each of these classifications one can deduce the (relative) telescope conjecture.

description: When ultrafast laser pulse strikes the crystal with a van Hove singularity in the phonon density of states, it can create a pair of anti-correlated in wave-vector acoustic phonons. As a result, the atomic fluctuations in either position or momentum become squeezed in such a way that their size might fall below the vacuum level. The ultrafast pulses can also generate a two-phonon bound (biphonon) state in which the constituent phonons are correlated and/or entangled. Here we show that via the interplay between one- and two-phonon interference the bound and squeezed two-phonon state in (110) oriented ZnTe single crystal can be manipulated. We demonstrate experimentally that when two biphonon ensembles are temporally and spatially overlapped, the strength of phonon squeezing and correlation can be controlled. However, due to the complementarity of one- and two-phonon interference a larger correlation comes at the expense of a reduced squeezing.

description: Background: The relationship between mastitis and antiretroviral therapy among HIV-positive, breast-feeding women is unclear. Methods: In the Breastfeeding, Antiretrovirals, and Nutrition (BAN) study, conducted in Lilongwe, Malawi, 2369 mother-infant pairs were randomized to a nutritional supplement group and to one of three treatment groups: maternal antiretroviral therapy (ART), infant nevirapine (NVP) or standard of care for 24 weeks of exclusive breast-feeding and 4 weeks of weaning. Among 1472 HIV-infected women who delivered live infants between 2004 and 2007, we estimated cumulative incidence functions and sub-distribution hazard ratios (HR) of mastitis or breast inflammation comparing women in maternal ART (n = 487) or infant nevirapine (n = 492) groups to the standard of care (n = 493). Nutritional supplement groups (743 took, 729 did not) were also compared. Results: Through 28-weeks post-partum, 102 of 1472 women experienced at least one occurrence of mastitis or breast inflammation. The 28-week risk was higher for maternal ART (risk difference (RD) 4.5, 95% confidence interval (CI) 0.9, 8.1) and infant NVP (RD 3.6, 95% CI 0.3, 6.9) compared to standard of care. The hazard of late-appearing mastitis or breast inflammation (from week 5–28) was also higher for maternal ART (HR 6.7, 95% CI 2.0, 22.6) and infant NVP (HR 5.1, 95% CI 1.5, 17. 5) compared to the standard of care. Conclusions: Mastitis or breast inflammation while breast-feeding is a possible side effect for women taking prophylactic ART and women whose infants take NVP, warranting additional research in the context of postnatal HIV transmission.

description: Several heavy-fermion metals display a quantum phase transition from an antiferromagnetic metal to a heavy Fermi liquid. In some materials, however, recent experiments seem to find that the heavy Fermi liquid phase can be directly tuned into a non-Fermi liquid phase without apparent magnetic order. We analyze a candidate state for this scenario where the local moment system forms a spin liquid with gapless fermionic excitations. We discuss the thermal conductivity and spin susceptibility of this fractionalized state both in two and, in particular, three spatial dimensions for different temperature regimes. We derive a variational functional for the thermal conductivity and solve it with a variational ansatz dictated by Keldysh formalism. In sufficiently clean samples and for an appropriate temperature window, we find that thermal transport is dominated by the spinon contribution which can be detected by a characteristic maximum in the Wiedemann-Franz ratio. For the spin susceptibility, the conduction electron Pauli paramagnetism is much smaller than the spinon contribution whose temperature dependence in three dimensions is logarithmically enhanced as compared to the Fermi liquid result.

description: We apply variational principles in the context of geometrothermodynamics. The thermodynamic phase space ${\cal T}$ and the space of equilibrium states ${\cal E}$ turn out to be described by Riemannian metrics which are invariant with respect to Legendre transformations and satisfy the differential equations following from the variation of a Nambu-Goto-like action. This implies that the volume element of ${\cal E}$ is an extremal and that ${\cal E}$ and ${\cal T}$ are related by an embedding harmonic map. We explore the physical meaning of geodesic curves in ${\cal E}$ as describing quasi-static processes that connect different equilibrium states. We present a Legendre invariant metric which is flat (curved) in the case of an ideal (van der Waals) gas and satisfies Nambu-Goto equations. The method is used to derive some new solutions which could represent particular thermodynamic systems.

description: Despite many ARPES investigations of iron pnictides, the structure of the electron pockets is still poorly understood. By combining ARPES measurements in different experimental configurations, we clearly resolve their elliptic shape. Comparison with band calculation identify a deep electron band with the dxy orbital and a shallow electron band along the perpendicular ellipse axis with the dxz/dyz orbitals. We find that, for both electron and hole bands, the lifetimes associated with dxy are longer than for dxz/dyz. This suggests that the two types of orbitals play different roles in the electronic properties and that their relative weight is a key parameter to determine the ground state.
