description: We introduce new fast canonical local algorithms for discrete and continuous spin systems. We show that for a broad selection of spin systems they compare favorably to the known ones except for the Ising +/-1 spins. The new procedures use discretization scheme and the necessary information have to be stored in computer memory before the simulation. The models for testing discrete spins are the Ising +/-1, the general Ising S or Blume-Capel model, the Potts and the clock models. The continuous spins we examine are the O(N) models, including the continuous Ising model (N=1), the ϕ^4 Ising model (N=1), the XY model (N=2), the Heisenberg model (N=3), the ϕ^4 Heisenberg model (N=3), the O(4) model with applications to the SU(2) lattice gauge theory, and the general O(N) vector spins with N\ge5.

The Holocaust and dark tourism
Creators: name: Jangula, Craig
Publisher: name: University of British Columbia
Year: 2010

description: There are many different topics that continue to be explored in the vast field of "Holocaust Studies." In dealing with any segment of history there is always an intersection where various disciplines such as politics, history, philosophy and ethics seem to collide. This is especially true in the recently defined area of "Dark Tourism." Dark Tourism takes a closer look at why people travel to sites of death and disaster, and examines the complex historical, political, ethical and moral rational behind these developments. There are seemingly endless dark places that people travel to such as, the Anne Frank House, Vimy Ridge, the Somme, the D-Day beaches, Gettysburg, and the Channel Islands. In more recent years, sites such as the Dakota apartments (where John Lennon was shot), Oklahoma City and Ground Zero have also become centers of Dark Tourism. It seems that the popularity of traveling to these types of places is increasing. With this in mind, researchers have become interested in studying this Dark Tourism phenomenon. Arguably some of the "darkest" of the dark sites people currently travel to are sites associated with the Holocaust. The severity of the Holocaust often makes it stand out as a candidate for special consideration within the broader field of "Tourism Studies" or even "Dark Tourism Studies" for that matter. The central purpose of this thesis is to explore how these dark Holocaust sites became tourist venues. This thesis will explore the contests over the right to interpret, ethical and moral dilemmas and the emerging dynamics of the commercialization and marketing of Holocaust sites as tourist venues. Hence, this thesis will chronicle and present these emotionally-charged and unresolved issues, and highlight the Dark Tourism dilemmas that threaten to become unsolvable.

description: The established scaling laws of the conductivity with temperature and doping are strong indications for the quantum nature of the metal-insulator transition in YH$_x$. Here we report the first results on the frequency scaling of the conductivity. Samples were brought from the insulating to the metallic phase by carrier doping via illumination. In the metallic phase, the sub-terahertz conductivity coincides with the dc data. These results do not agree with the simplest picture of a quantum-phase transition.

description: El objetivo del presente estudio es aplicar una metodología rigurosa para estimar la incertidumbre de las mediciones utilizando el método adaptativo de la simulación de Monte Carlo (MCM). Se tomó como ejemplo la estimación de la incertidumbre en la medición del área de un triángulo. El valor del área (y) y su incertidumbre asociada (uy) se calcularon en base a un algoritmo que se programó en lenguaje Maple 12, generando un total de 10000 valores del mensurando. Para calcular el intervalo de confianza (o intervalo de cobertura), se exportaron estos valores a la hoja de cálculo MS Excel, se obtuvieron los porcentajes acumulados de la función de distribución de probabilidad (CPDF) y se evaluaron los valores extremos del intervalo de cobertura (yinf, ysup) a una probabilidad del 95%. A partir de los resultados se trazó el histograma y se demostró que siguen una distribución normal. Para verificar la estabilidad estadística se aplicó el procedimiento adaptativo del suplemento 1 de la guía GUM ISO 2008. Los cálculos se repitieron 3 veces, hasta que se obtuvo la precisión adecuada. Los valores de los parámetros finales del mensurando en cm2 fueron: y=50.72, uy=0.13, yinf=50.48, ysup=50.96. También se aplicó el método clásico GUM 1995 o ley de propagación de la incertidumbre, encontrándose los siguientes valores: y=50.72, uy=0.25, yinf=50.21, ysup=51.22. Al comparar los dos métodos se observó que la técnica de simulación tiene mayor precisión.

Here I will focus on the outermost regions of galaxies which can be observed with sufficient sensitivity and resolution at 21-cm as to enlighten the interplay between galaxies and the intergalactic gas, the competing race between the local dark matter gravity and the external ionizing radiation field. Tracing the gas distribution out to large galactocentric radii will be complementary to QSO's Ly$α$ absorption studies for understanding the evolution of the dark and visible matter of the Universe.

description: Popcorn is an extremely popular snack food in the world today. Thermodynamics can be used to analyze how popcorn is produced. By treating the popping mechanism of the corn as a thermodynamic expansion, a method of increasing the volume or size of a kernel of popcorn can be studied. By lowering the pressure surrounding the unpopped kernel, one can use a thermodynamic argument to show that the expanded volume of the kernel when it pops must increase. In this project, a variety of experiments are run to test the validity of this theory. The results show that there is a significant increase in the average kernel size when the pressure of the surroundings is reduced.

description: Consistency checks of $Λ$CDM predictions with current cosmological data sets may illuminate the types of changes needed to resolve cosmological tensions. To this end, we modify the CLASS Boltzmann code to create phenomenological amplitudes, similar to the lensing amplitude parameter $A_L$, for the Sachs-Wolfe, Doppler, early Integrated Sachs-Wolfe (eISW), and Polarization contributions to the CMB temperature anisotropy, and then we include these additional amplitudes in fits to the Planck TT power spectrum. We find that allowing one of these amplitudes to vary at a time results in little improvement over $Λ$CDM alone suggesting that each of these physical effects are being correctly accounted for given the current level of precision. Further, we find that the only pair of phenomenological amplitudes that results in a significant improvement to the fit to Planck temperature data results from varying the amplitudes of the Sachs-Wolfe and Doppler effects simultaneously. However, we show that this model is really just refinding the $Λ$CDM + $A_L$ solution. We test adding our phenomenological amplitudes as well as $N_{\textrm{eff}}$, $Y_{\textrm{He}}$, and $n_{\textrm{run}}$ to $Λ$CDM + $A_L$ and find that none of these model extensions provide significant improvement over $Λ$CDM + $A_L$ when fitting Planck temperature data. Finally, we quantify the contributions of both the eISW effect and lensing on the constraint of the physical matter density from Planck temperature data by allowing the phenomenological amplitude from each effect to vary. We find that these effects play a relatively small role (the uncertainty increases by $3.5\%$ and $16\%$ respectively) suggesting that the overall photon envelope has the greatest constraining power.

description: We present lifetime measurements of the 7S1/2 level and the 6p manifold of rubidium. We use a timecorrelated single-photon counting technique on a sample of 85Rb atoms confined and cooled in a magneto-optic trap. The upper state of the 5P1/2 repumping transition serves as the resonant intermediate level for twophoton excitation of the 7s level. A probe laser provides the second step of the excitation, and we detect the decay of atomic fluorescence to the 5P3/2 level at 741 nm. The decay process feeds the 6p manifold that decays to the 5s ground state emitting UV photons. We measure lifetimes of 88.07 +- 0.40 and 120.7 +- 1.2 ns for the 7S1/2 level and 6p manifold, respectively; the hyperfine splitting of the 7S1/2 level is 282.6 +- 1.6 MHz. The agreement with theoretical calculations confirms the understanding of the wave functions involved and provides confidence on the possibility of extracting weak interaction constants from a parity nonconservation measurement.

description: We analyze the rest-optical emission-line spectra of $z\sim2.3$ star-forming galaxies in the complete MOSFIRE Deep Evolution Field (MOSDEF) survey. In investigating the origin of the well-known offset between the sequences of high-redshift and local galaxies in the [O III]5008/H$β$ vs. [N II]6585/H$α$ ("[N II] BPT") diagram, we define two populations of $z\sim2.3$ MOSDEF galaxies. These include the "high" population that is offset towards higher [O III]5008/H$β$ and/or [N II]6585/H$α$ with respect to the local SDSS sequence and the "low" population that overlaps the SDSS sequence. These two groups are also segregated within the [O III]5008/H$β$ vs. [S II]6718,6733/H$α$ and the [O III]4960,5008/[O II]3727,3730 (O$_{32}$) vs. ([O III]4960,5008+[O II]3727,3730)/H$β$ (R$_{23}$) diagram, which suggests qualitatively that star-forming regions in the more offset galaxies are characterized by harder ionizing spectra at fixed nebular oxygen abundance. We also investigate many galaxy properties of the split sample and find that the "high" sample is on average smaller in size and less massive, but has higher specific star-formation rate and star-formation-rate surface density values and is slightly younger compared to the "low" population. From Cloudy+BPASS photoionization models, we estimate that the "high" population has a lower stellar metallicity (i.e., harder ionizing spectrum) but slightly higher nebular metallicity and higher ionization parameter compared to the "low" population. While the "high" population is more $α$-enhanced (i.e., higher $α$/Fe) than the "low" population, both samples are significantly more $α$-enhanced compared to local star-forming galaxies with similar rest-optical line ratios. These differences must be accounted for in all high-redshift star-forming galaxies -- not only those "offset" from local excitation sequences.

The securitisation of humanitarian migration
Creators: name: Watson, Scott D.
Publisher: name: University of British Columbia
Year: 2010

description: The different responses of Canada and Australia to the arrival of asylum seekers present an interesting puzzle for IR scholars. My analysis analyzes how the use of the coercive capacity of the state against refugees and asylum seekers has come to be regarded as essential in some liberal democratic states while in others these policies remain unacceptable? Using a focused case comparison between Canada and Australia, I show that discursive practices of influential societal and political actors construct the identity of refugees and the receiving state in such a way that makes certain policy choices acceptable to state leaders. In cases where the securitising discourse constructs refugees as the primary referent object of a security threat and the receiving state as a responsible humanitarian international citizen, state leaders adopt policies consistent with norms of the international refugee regime. In cases where this discourse is challenged, societal actors attempt to reconstruct the identity of refugees as security threats to the receiving state. When these securitising attempts are successful, state leaders more readily adopt policies designed to ’protect’ the state rather than refugees. To support these conclusions, I employ discourse and textual analysis during three notable refugee ’crises’ in each state. In the Australian case, the three crises are: the 1979 Indo-Chinese boat people exodus, the 1992 boat arrivals and the 2001 Tampa affair. In Canada, I examine the 1979 Indo-Chinese boat people exodus, the 1986-1987 boat landings and the 1999 boat arrivals. In all six crises, humanitarian and communitarian securitising discourses reconstructed the identity of asylum seekers, their home states and the receiving states, limiting policy options available to state leaders. My findings have important broader theoretical and practical implications. Theoretically, my work contributes to a better theoretical understanding of the conditions under which the coercive capacity the state can be employed; also, the dissertation makes a significant contribution to understanding the role of discursive practices in limiting policy options and has important practical implications for the media and societal leaders in influencing/challenging the securitising attempts of state leaders.

description: Coherent imaging through scatter is a challenging task in computational imaging. Both model-based and data-driven approaches have been explored to solve the inverse scattering problem. In our previous work, we have shown that a deep learning approach can make high-quality and highly generalizable predictions through unseen diffusers. Here, we propose a new deep neural network (DNN) model that is agnostic to a broader class of perturbations including scatterer change, displacements, and system defocus up to 10X depth of field. In addition, we develop a new analysis framework for interpreting the mechanism of our DNN model and visualizing its generalizability based on an unsupervised dimension reduction technique. We show that our DNN can unmix the scattering-specific information and extract the object-specific information so as to achieve generalization under different scattering conditions. Our work paves the way to a highly robust and interpretable deep learning approach to imaging through scattering media.
title: Diversity, Distribution and Evolution of the Planktonic Diatom Family Chaetocerotaceae
Creators: name: Gaonkar, Chetan Chandrakant
Publisher: name: The Open University
Year: 2017

description: The number and abundance of diatom species in environmental samples are counted traditionally by means of light microscopy (LM). However, recognizing –let alone, counting- species is often challenging because of the existence of cryptic species and intraspecific phenotypic plasticity. Proper characterization requires isolation of cells, growing them into monoclonal cultures, and characterizing the cultures genetically and morphologically. However, not all species grow in culture, featureless ones are less likely to be isolated, and the procedure is laborious. High-throughput sequencing (HTS) metabarcoding bypasses morphology; DNA is collected from environmental samples, a particular marker sequenced, and the resulting sequences sorted into clusters or terminal clades assumed to represent species. Yet, reference barcodes of taxonomically validated species are needed to identify these clades. This exercise is the main aim of my thesis.

 Since it is impossible to do this for all the diversity within a PhD thesis project, we selected Chaetocerotaceae, an abundant and diverse family of marine planktonic diatoms, containing two genera: Chaetoceros and Bacteriastrum. Its members uniquely share setae; thin siliceous tubes emerging from the valve corners, facilitating detection in samples. Strains were obtained from the Gulf of Naples (GoN), from Central Chile and Roscoff – at sites for which LTER time series data are available.

 A total of 270 strains were obtained from these sites, and their 18S- and partial 28S rDNA sequences and morphological information gathered. The strains grouped into 60 genetically distinct species, thus providing a dataset of validated Chaetocerotacean 18S reference barcodes. Inferred molecular phylogenies showed monophyletic Chaetocerotaceae as well as monophyletic Bacteriastrum inside paraphyletic Chaetoceros, and the presence of cryptic diversity. To start with taxonomic updates, the species C. sporotruncatus and C. dichatoensis were described within the C. socialis species-complex based on spore morphology and sequence differences. Several rDNA sequences contained spliceosomal introns (ca. 100bp) and/or group-I introns (ca. 400bp). Phylogenies inferred from the introns did not corroborate rDNA phylogenies, suggesting horizontal gene transfer. Presence/absence of introns in conspecific strains sampled in different seasons suggests population differentiation between these seasons. A HTS dataset consisting of V4-sequences (part of 18S) from 48 seawater samples taken over the seasons in the GoN revealed 76 terminal clades of which 46 grouped with a reference barcode. Some of these species occur year-round whereas most others are seasonal. Surprisingly, of the 30 clades belonging to unknown Chaetocerotacean species, two appear to be among the most abundant in the GoN.

description: The ATLAS and CMS collaborations at the Large Hadron Collider (LHC) have performed a wide range of searches for physics beyond the standard model (BSM), during their run 1 at \Unit{8}{TeV}. Many of these searches target supersymmetric signatures. In order to ease the interpretation of these results, simplified models have been introduced recently. They provide a context in which the experimental results are interpreted as upper limits on production cross sections, introducing only a limited set of new BSM particles. Given a full theoretical model, it is nevertheless still a non-trivial task to decide, whether any of these simplified models results exclude the theory or not. A software framework called \smodels has been developed recently. It decomposes a given $\mathbb{Z}_2$-symmetric BSM model into its simplified models spectra (SMS) topologies and matches them with a database of the experimental simplified models results. The database that contains the experimental upper limits was maintained and improved within the scope of this thesis. A software tool to access the database as conveniently as possible was developed and constantly enhanced. This tool was used to validate the framework and restructure the database. The latest official version of the software tool, \smodelsv was applied to a scan over a parameter space determined by a low fine tuned (LFT) scenario. This scenario is a subset of the 19-parameter phenomenological minimal supersymmetric model (pMSSM). The motivation behind this region of parameter space is the question of ``naturalness'' within the pMSSM, i.e. how the mass of the newly found Higgs boson is stabilized at the electroweak scale. Another instance is to understand, if the concept of naturalness is compatible with the fact, that no experimental evidence for the existence of supersymmetry has been found so far. The scan is analysed and interpreted in this thesis. The mass spectrum in this LFT scenario is found to have very light top and bottom squarks often accompanied by light electro weak sparticles, allowing rather complex decay patterns. Amongst others this results in several interesting SMS topologies, for which no applicable simplified model results are available by now. Those topologies are understood in terms of supersymmetric decay chains. Regions of parameter space, which still remain unchallenged by current SUSY searches at the LHC are provided. Interesting new topologies for future SMS interpretation of data collected by the ATLAS and the CMS collaborations are proposed.

description: In the spotting light of an intensive climate policy and an evolving dependency on imported fossil fuels in the mobility sector, electric vehicles receive a lot of attention. The deployment of electric vehicles is regarded as an effective policy strategy to meet emissions (CO2) reduction targets. Sustainable and climate friendly policies should encourage innovation as this can stimulate efficiency when using the natural capital and thus foster new economic opportunities. The innovations, regarded as new technologies, should be properly directed towards a beneficial diffusion that would include social, economic and environmental improvements, by enabling winwin synergies between market components like government, industry and consumer. Following the need of identifying proper models for integrating the electric mobility in a common market, it became clear that solely market forces cannot facilitate such a transition alone. Thus, the market remains just a catalyzer for the electric mobility in the case when the policy, the relevant industries and the consumer are decisively committed to such a technological change. Functioning market models rely on synergetic and productive relationships and interaction between the participants. Moreover the participants activities, considered as specific business models, should be viable in the long term in order to consolidate the market positions. Exactly such strategy is adopted by most of existing players; however, the pace of deployment is relatively slow but has a stable up-trend. In the end, the deployment of E-mobility will mostly depend not on the way that technologies will be developed and promoted, but predominantly on the capability to organize and administer the operations of sophisticated terrain of market actors

description: We revisit the problem of point-contact tunnel junctions involving one-dimensional superconductors and present a simple scheme for computing the full current-voltage characteristics within the framework of the non-equilibrium Keldysh Green function formalism. We address the effects of different pairing symmetries combined with magnetic fields and finite temperatures at arbitrary bias voltages. We discuss extensively the importance of these results for present-day experiments. In particular, we propose ways of measuring the effects found when the two sides of the junction have dissimilar superconducting gaps and when the symmetry of the superconducting states is not the one of spin-singlet pairing. This last point is of relevance for the study of the superconducting state of certain organic materials like the Bechgaard salts and, to some extent, for ruthenium compounds.

Boosting Freeze-in through Thermalization

description: If the interaction rates between the visible and the dark sectors were never strong enough, the observed dark matter relic abundance could have been produced in the early Universe by non-thermal processes. This is what occurs in the so-called freeze-in mechanism. In the simplest version of the freeze-in paradigm, after dark matter is produced from the standard model thermal bath, its abundance is frozen and remains constant. However, thermalization and number-changing processes in the dark sector can have strong impacts, in particular enhancing the dark matter relic abundance by several orders of magnitude. Here we show that this enhancement can be computed from general arguments as the conservation of energy and entropy, independently from the underlying particle physics details of the dark sector. We also note that this result is quite general, and applies to FIMP production independently of being UV- or IR-dominated.

description: Neutral hydrogen mapping of several small, very low column density High Velocity Clouds (HVC), using the Arecibo telescope, is reported. Some were found serendipitously superimposed at distinct velocities on largerHVCs; others were found to comprise the four most isolated low column density sources in the observations of Lockman et al. but proved to be individually much smaller than the Green Bank 140 Foot telescope beam. We call these clouds ``mini-HVC'' to distinguish them from the larger and denser Compact High Velocity Clouds (CHVC). Peak column densities are typically a few X 10^18 cm^-2 averaged over the Arecibo 3.2' beam, and diameters to our detection limit ~ 10^18 cm^-2 range from 9' to 35'. These column densities and angular diameters overlap with those for CHVC, but are typically smaller. We consider three possiblities: (1) that most mini-HVC are related to the Magellanic Stream, (2) that most mini-HVC are part of M31's retinue of CHVC, or (3) that the mini-HVC are simply the low column density tail of the distribution of CHVC. None of these possibilities can be rejected as yet, given the selection biases in our sample. We also discuss controversies about the amount of ionized hydrogen in CHVC and mini-HVC, which may be mainly ionized, and the implications of these small clouds for Lyman Limit Systems.

description: We introduce a novel class of higher-order, three-mode states called K-dimensional trio coherent states. We study their mathematical properties and prove that they form a complete set in a truncated Fock space. We also study their physical content by explicitly showing that they exhibit nonclassical features such as oscillatory number distribution, sub-poissonian statistics, Cauchy-Schwarz inequality violation and phase-space quantum interferences. Finally, we propose an experimental scheme to realize the state with K=2 in the quantized vibronic motion of a trapped ion.

description: We address Bessel photonic lattices of radial symmetry imprinted in cubic Kerr-type nonlinear media and show that they support families of stable dipole-mode solitons featuring two out-of-phase light spots located in different lattice rings. We show that the radial symmetry of the Bessel lattices afford a variety of unique soliton dynamics including controlled radiation-free rotation of the dipole-mode solitons.

description: Bereits im April/Mai 2006 und im April/Mai 2008 wurde die Zufriedenheit der Landmaschinenhändler mit ihren Herstellern im Rahmen einer schriftlichen Befragung abgefragt. Eine Online-Befragung erfolgte dann im April/Mai 2015. Insgesamt nahmen 160 Händler an der Befragung teil. Wie 2006 und 2008 wurde auch 2015 die Bewertung der Händler zu fünf unterschiedlichen Kategorien abgefragt: - Traktoren - Mähdrescher - Futtererntetechnik - Bodenbearbeitung und Saat - Technik für Pflanzenschutz und Düngung. Abgefragt wurden z.B.: - Gesamtzufriedenheit mit jeweiligem Hauptlieferanten - Zufriedenheit mit einzelnen Marketingmaßnahmen im Detail Die Marketingmaßnahmen umfassen z.B. die Bereiche: - Produktprogramm - Zukunft der Lieferanten im Wettbewerb - Beziehung zu Lieferanten. Die Gesamtzufriedenheit setzt sich aus der Zufriedenheit in den einzelnen Bereichen zusammen. Um die Bedeutung einzelner Bereiche für die Gesamtzufriedenheit zu bewerten, wurde der Korrelationskoeffizient zwischen der Gesamtzufriedenheit und dem jeweiligen Bereich berechnet. Zusammenfassend kann man einen zumindest leichten Anstieg bei der Gesamtzufriedenheit feststellen. Lediglich in der Produktgruppe der Mähdrescher kam es zu einer insgesamt schlechteren Bewertung als 2006. Bezogen auf alle Beurteilungen konnte die Futtererntetechnik wie schon in den Vorjahren am besten abschneiden.
The Cosmological OTOC: Formulating new cosmological micro-canonical correlation functions for random chaotic fluctuations in Out-of-Equilibrium Quantum Statistical Field Theory

description: The out-of-time-ordered correlation (OTOC) function is an important new probe in quantum field theory which is treated as a significant measure of random quantum correlations. In this paper, with the slogan "Cosmology meets Condensed Matter Physics" we demonstrate a formalism using which for the first time we compute the Cosmological OTOC during the stochastic particle production during inflation and reheating following canonical quantization technique. In this computation, two dynamical time scales are involved, out of them at one time scale the cosmological perturbation variable and for the other the canonically conjugate momentum is defined, which is the strict requirement to define time scale separated quantum operators for OTOC and perfectly consistent with the general definition of OTOC. Most importantly, using the present formalism not only one can study the quantum correlation during stochastic inflation and reheating, but also study quantum correlation for any random events in Cosmology. Next, using the late time exponential decay of cosmological OTOC with respect to the dynamical time scale of our universe which is associated with the canonically conjugate momentum operator in this formalism we study the phenomena of quantum chaos by computing the expression for {\it Lyapunov spectrum}. Further, using the well known Maldacena Shenker Stanford (MSS) bound, on Lyapunov exponent, $λ\leq 2π/β$, we propose a lower bound on the equilibrium temperature, $T=1/β$, at the very late time scale of the universe. On the other hand, with respect to the other time scale with which the perturbation variable is associated, we find decreasing but not exponentially decaying behaviour, which quantifies the random correlation at out-of-equilibrium. Finally, we have studied the classical limit of the OTOC to check the consistency with the large time limiting behaviour.
