description: Hybrid nanowires with proximity-induced superconductivity in the topological regime host Majorana zero modes (MZMs) at their ends, and networks of such structures can produce topologically protected qubits. In a double-island geometry where each segment hosts a pair of MZMs, inter-pair coupling mixes the charge parity of the islands and opens an energy gap between the even and odd charge states at the inter-island charge degeneracy. Here, we report on the spectroscopic measurement of such an energy gap in an InAs/Al double-island device by tracking the position of the microwave-induced quasiparticle (qp) transitions using a radio-frequency (rf) charge sensor. In zero magnetic field, photon assisted tunneling (PAT) of Cooper pairs gives rise to resonant lines in the 2e-2e periodic charge stability diagram. In the presence of a magnetic field aligned along the nanowire, resonance lines are observed parallel to the inter-island charge degeneracy of the 1e-1e periodic charge stability diagram, where the 1e periodicity results from a zero-energy sub-gap state that emerges in magnetic field. Resonant lines in the charge stability diagram indicate coherent photon assisted tunneling of single-electron states, changing the parity of the two islands. The dependence of resonant frequency on detuning indicates a sizable (GHz-scale) hybridization of zero modes across the junction separating islands.

description: We propose an experimental realization of discrete quantum random walks using neutral atoms trapped in optical lattices. The random walk is taking place in position space and experimental implementation with present day technology --even using existing set-ups-- seems feasible. We analyze the influence of possible imperfections in the experiment and investigate the transition from a quantum random walk to the classical random walk for increasing errors and decoherence.

description: Episodic accretion-driven outbursts are an extreme manifestation of accretion variability. It has been proposed that the development of gravitational instabilities in the proto-circumstellar medium of massive young stellar objects (MYSOs) can lead to such luminous bursts, when clumps of fragmented accretion discs migrate onto the star. We simulate the early evolution of MYSOs formed by the gravitational collapse of rotating 100 M pre-stellar cores and analyze the characteristics of the bursts that episodically accompany their strongly time-variable protostellar lightcurve. We predict that MYSOs spend ~ 10^3 yr (~ 1.7\%) of their modelled early 60 kyr experiencing eruptive phases, during which the peak luminosity exceeds the quiescent pre-burst values by factors from 2.5 to more than 40. Throughout these short time periods, they can acquire a substential fraction (up to ~ 50 \%) of their zero-age-main sequence mass. Our findings show that fainter bursts are more common than brighter ones. We discuss our results in the context of the known bursting MYSOs, e.g. NGC6334I-MM1 and S255IR-NIRS3, and propose that these monitored bursts are part of a long-time ongoing series of eruptions, which might, in the future, be followed by other luminous flares.

description: The purpose of this participatory research was to gain the perspective from the youth of a plains tribe Native American community about their concept of mental health and wellness, and to discover how youth participants related these ideas and narratives to their life processes and experiences. This study also investigated the methodological use of participatory photo-elicitation for talking about mental health and using grounded research theory to explore what types of themes and testimony are most common. This participatory research was done in partnership with an American Indian-operated health promotion and disease prevention program that is tackling inequity in mental health youth outcomes. Forty-one children ages 9 to 17 participated in this qualitative study. Semi-structured one-one-one interviews using the participatory photo-elicitation method generated conversation and formed the basis of the raw data. Grounded theory was employed in both data collection and analysis. A “zig-zag” pattern of data collection defined basic subgroups of children by age, allowing for a saturation of themes.  The five major themes that emerged were: strategies for mental health, ecology and mental health, identity and mental health, social support/loss of social support and mental health, and, ambivalent feelings/thoughts about mental health. Categories within themes held across the three age groups and overlapping themes held theoretical importance. Photo-creation followed by photo-elicitation resulted in a rich relay of diverse testimony including literal translation, metaphor, analogy, shadowed data, and personally recounted lived experiences, often shared via expository dialogue.  The saturation of themes showed fidelity to developmental groupings. Identity, particularly Native identity overlapped with themes of strategy and ecology. This study heightens awareness that most older children in this sample identified loss of a loved one as part of their lived experience of mental health. A majority of children spoke of mental health and wellness strategies that included finding balance, healing, seeking social support and inhabiting at least one positive ecology.  Finally, many children related their concept of mental health to their natural surroundings and the sky. Some children used visual and verbal metaphors such as the medicine wheel, a Native quilt, the undulation of a landscape, and the tipi to help describe their concept of mental health and wellness.

description: Monolayer semiconductors are atomically thin quantum wells with strong confinement of electrons in two-dimensional (2D) plane. Here, we experimentally study the out-of-plane polarizability of excitons in hBN-encapsulated monolayer WSe$_{2}$ in strong electric fields of up to 1.6 V/nm (16 MV/cm). We monitor free and bound exciton photoluminescence peaks with increasing electric fields at a constant carrier density, carefully compensating for unintentional photodoping in our double-gated device at 4K. We show that the Stark shift is < 0.4 meV despite the large electric fields applied, yielding an upper limit of polarizability α$_{z}$ to be ~ 10$^{-11}$ Dm/V. Such a small polarizability, which is nearly two orders of magnitude smaller than the previously reported value for MoS$_{2}$, indicates strong atomic confinement of electrons in this 2D system and highlights the unusual robustness of free excitons against surface potential fluctuations.

description: UBC owns and operates many buildings where a large population live, study or work. UBC intends to manage the impact of these buildings on sustainability and wellbeing of the people through Green Building Action Plan (GBAP) towards a human and ecological net positive condition by 2035. Five components including Air, Water, Light, Nourishment and Movement of the GBAP which are under the Health and Wellbeing emergent component are studied in this report. The context of this report is focused on the institutional buildings at UBC. Through review and analysis of existing UBC standards and guidelines as well as other industry standards and guidelines, this research project has identified recommendations for improvements that support health and wellbeing in UBC buildings. Through a SWOT analysis, it concludes the applicability and its corresponding requirements in relation to UBC’s policies. This report recommends UBC to extend its guidelines to evaluate implementation of established assessment frameworks to the wide range of buildings, focus on retrofit in addition to new design, and raise awareness among stakeholders and collaborators between various disciplines. It is recommended to consider the effectiveness of the certification process on achievement of UBC goals and objectives. Several gaps and shortcomings have been identified, most notably behavioural requirements, better documentation, and developing measurement and monitoring tools.

subject: Architecture--Preservation

description: This thesis contributes to the understanding of the history of preservation design by examining one of its main modes of expression: the “window to the past.” Appearing in architectural publications beginning in the early 1980s and becoming emblematic of the aesthetics of preservation design by the 1990s and 2000s, this visual device represents the historic origins of the building through the peeling away of layers on a single surface to expose materiality, texture, craft, or color.  The development of windows to the past was documented by examining three architectural journals from 1945 through 2013: The Architectural Review, Casabella, and Detail. Windows to the past were disseminated in architectural journals through photographic framing, creative layouts, journal editorship, and color photography and printing. Despite its ubiquity in projects that incorporated old buildings and new designs, the approach, through the framing of existing architecture and the use of contemporary architectural materials, is often opportunistic, exploiting the visual characteristics of historic architecture and diminishing the role of history as part of architectural discourse. However, when successfully employed, the technique can function as a device that moves beyond the nostalgic notion of age and into the realm of didacticism, where it can inform the audience not only of the building’s age, but also of its craft, construction techniques, and history. By evaluating one of the most significant and prevalent modes of expression in preservation design, architectural criticism and discourse can begin to better understand the relationship between the existing and the intervening.
Absorbing Boundary Conditions for Time-dependent Schrödinger equations: A Density-matrix Formulation

Year: 2018
Subjects: subject: Numerical Analysis (math.NA)

description: This paper presents some absorbing boundary conditions (ABC) for simulations based on the time-dependent density-functional theory (TDDFT). The boundary conditions are expressed in terms of the elements of the density-matrix, and it is derived from the full model over a much larger domain. To make the implementation much more efficient, several approximations for the convolution integral will be constructed with guaranteed stability. These approximations lead to modified density-matrix equations at the boundary. The effectiveness is examined via numerical tests.

description: We describe a grid generation procedure designed to construct new classes of orthogonal coordinate systems for binary black hole spacetimes. The computed coordinates offer an alternative approach to current methods, in addition to providing a framework for potentially more stable and accurate evolutions of colliding black holes. As a particular example, we apply our procedure to generate appropriate numerical grids to evolve Misner's axisymmetric initial data set representing two equal mass black holes colliding head-on. These new results are compared with previously published calculations, and we find generally good agreement in both the waveform profiles and total radiated energies over the allowable range of separation parameters. Furthermore, because no specialized treatment of the coordinate singularities is required, these new grids are more easily extendible to unequal mass and spinning black hole collisions.

description: Refrigeration and chiller optimization is an important and well studied topic in mechanical engineering, mostly taking advantage of physical models, designed on top of over-simplified assumptions, over the equipments. Conventional optimization techniques using physical models make decisions of online parameter tuning, based on very limited information of hardware specifications and external conditions, e.g., outdoor weather. In recent years, new generation of sensors is becoming essential part of new chiller plants, for the first time allowing the system administrators to continuously monitor the running status of all equipments in a timely and accurate way. The explosive growth of data flowing to databases, driven by the increasing analytical power by machine learning and data mining, unveils new possibilities of data-driven approaches for real-time chiller plant optimization. This paper presents our research and industrial experience on the adoption of data models and optimizations on chiller plant and discusses the lessons learnt from our practice on real world plants. Instead of employing complex machine learning models, we emphasize the incorporation of appropriate domain knowledge into data analysis tools, which turns out to be the key performance improver over state-of-the-art deep learning techniques by a significant margin. Our empirical evaluation on a real world chiller plant achieves savings by more than 7% on daily power consumption.

Note on the space group selection rule for closed strings on orbifolds

description: It is well-known that the space group selection rule constrains the interactions of closed strings on orbifolds. For some examples, this rule has been described by an effective Abelian symmetry that combines with a permutation symmetry to a non-Abelian flavor symmetry like $D_4$ or $Δ(54)$. However, the general case of the effective Abelian symmetries was not yet fully understood. In this work, we formalize the computation of the Abelian symmetry that results from the space group selection rule by imposing two conditions only: (i) well-defined discrete charges and (ii) their conservation. The resulting symmetry, which we call the space group flavor symmetry $D_S$, is uniquely specified by the Abelianization of the space group. For all Abelian orbifolds with $N=1$ supersymmetry we compute $D_S$ and identify new cases, for example, where $D_S$ contains a $Z_2$ dark matter-parity with charges 0 and 1 for massless and massive strings, respectively.

description: I examined the relationship between teacher effectiveness as measured by the number of learn units students required to meet an objective and the number of competencies mastered within the categories of teacher repertoires composing the CABAS® rank. Twenty preschool teachers participated in the study. A statistical analysis was used to investigate the degree to which these variables negatively correlated with each other. The results showed that the more competencies teachers mastered, the fewer learn units students required to meet an objective. A second experiment was conducted as an experimental analysis of the correlations found in the descriptive analysis. An adapted alternating treatments design was used to analyze the relationship between the number of competencies teachers mastered and the number of learn units their student required to meet an objective. Four teachers and four teacher assistants participated in the study. The teachers and teacher assistants each taught two sight word objectives for a student with bidirectional naming and a student without bidirectional naming. The results did not show a functional relationship between the number of competencies mastered and a lower LUC (learn unit to criterion). Teachers with more competencies mastered did not present fewer learn units for their students to meet an objective when compared to teacher assistants who had fewer competencies mastered. Possible explanations for a lack of a functional relationship found in Experiment 2 are discussed.

description: We begin with the existence of groups with trivial duals for cardinals aleph_n (n in omega). Then we derive results about strongly aleph_n-free abelian groups of cardinality aleph_n (n in omega) with prescribed free, countable endomorphism ring. Finally we use combinatorial results of [Sh:108], [Sh:141] to give similar answers for cardinals >aleph_omega. As in Magidor and Shelah [MgSh:204], a paper concerned with the existence of kappa-free, non-free abelian groups of cardinality kappa, the induction argument breaks down at aleph_omega. Recall that aleph_omega is the first singular cardinal and such groups of cardinality aleph_omega do not exist by the well-known Singular Compactness Theorem (see [Sh:52]).

description: We discuss several methods for unambiguous state discrimination of N symmetric coherent states using linear optics and photodetectors. One type of measurements is shown to be optimal in the limit of small photon numbers for any N. For the special case of N=4 this measurement can be fruitfully used by the receiving end (Bob) in an implementation of the BB84 quantum key distribution protocol using faint laser pulses. In particular, if Bob detects only a single photon the procedure is equivalent to the standard measurement that he would have to perform in a single-photon implementation of BB84, if he detects two photons Bob will unambiguously know the bit sent to him in 50% of the cases without having to exchange basis information, and if three photons are detected, Bob will know unambiguously which quantum state was sent.

What Should We Interpret First In An Archaeological Site: A Value-Based Identification Of Character-Defining Features In First Qin Emperor’s Mausoleum

description: This thesis proposed a method for the value-based identification of the site’s character-defining features. I contribute to solving a common problem at large heritage sites, which is how to present a sense of the whole site when only small pieces are visible and have been excavated.

As a case study, I focus on the First Qin Emperor’s Mausoleum constructed from 247-208 BC, because if reflects this tension between the entire heritage site and the excavated fragments. The Terra-Cotta Army Museum is known around the world, but it is only a small portion of the entire mausoleum site, the first in-situ museum as built in 1979 to exhibit the pits of terra-cotta figures, and it is an astounding 1.5 km east of the core mausoleum area. To fix the problem, and present a more complete site interpretation, the Shaanxi Cultural Relics Bureau constructed the mausoleum site park in 2009.

However, it failed to solve the problem. The official tourist investigation survey done between 2012 and 2014 revealed that the Terra-Cotta Army Museum was still eclipsing the rest of the site.
My thesis shows that in order to better understand the whole site, its major character-defining features must be presented to the public in a visible, physical way. Through my value-based method, I identified the axial paths and perimeter walls as the character-defining features that although primary in the hierarchy of importance, are not sufficiently visible to the public and therefore go by un-noticed. Because what is most important is not visible, I conclude by arguing for a partial reconstruction of the perimeter wall next to the remaining wall fragment and on the ancient foundation.
Dynamical Vacuum in Quantum Cosmology

description: By regarding the vacuum as a perfect fluid with equation of state p=-rho, de Sitter's cosmological model is quantized. Our treatment differs from previous ones in that it endows the vacuum with dynamical degrees of freedom. Instead of being postulated from the start, the cosmological constant arises from the degrees of freedom of the vacuum regarded as a dynamical entity, and a time variable can be naturally introduced. Taking the scale factor as the sole degree of freedom of the gravitational field, stationary and wave-packet solutions to the Wheeler-DeWitt equation are found. It turns out that states of the Universe with a definite value of the cosmological constant do not exist. For the wave packets investigated, quantum effects are noticeable only for small values of the scale factor, a classical regime being attained at asymptotically large times.

description: While mathematical problem solving and problem posing are central to good mathematics teaching and mathematical learning, no criteria exist for what makes a good mathematics problem. This grounded theory study focused on defining attributes of good mathematics problems as determined by students, teachers, and mathematicians. The research questions explored the similarities and differences of the responses of these three populations. The data were analyzed using the grounded theory approach of the constant comparative method. Fifty eight students from an urban private school, 15 teachers of mathematics, and 7 mathematicians were given two sets of problems, one with 10 algebra problems and one with 10 number theory problems, and were asked choose which problems they felt were the “best” and the “least best”. Once their choices were made, they were asked to list the attributes of the problems that lead to their choices. Responses were coded and the results were compared within each population between the two different problem sets and between populations. The results of the study show that while teachers and mathematicians agree, for the most part, about what attributes make a good mathematics problem, neither of those populations agreed with the students. The results from this study may be useful for teachers as they write or evaluate problems to use in their classes.

description: An overview of rare events algorithms based on large deviation theory (LDT) is presented. It covers a range of numerical schemes to compute the large deviation minimizer in various setups, and discusses best practices, common pitfalls, and implementation trade-offs. Generalizations, extensions, and improvements of the minimum action methods are proposed. These algorithms are tested on example problems which illustrate several common difficulties which arise e.g. when the forcing is degenerate or multiplicative, or the systems are infinite-dimensional. Generalizations to processes driven by non-Gaussian noises or random initial data and parameters are also discussed, along with the connection between the LDT-based approach reviewed here and other methods, such as stochastic field theory and optimal control. Finally, the integration of this approach in importance sampling methods using e.g. genealogical algorithms is explored.

The purpose of this study is to try to understand the factors that are driving cryptocurrency-related trading activities. Focusing on the well-established cryptocurrency called Bitcoin, we find that online search popularity and the volume of trade in unrelated stock markets positively and negatively, respectively, influence Bitcoin trading volume. We also find no statistical evidence that the underlying sentiment behind relevant financial news influence Bitcoin trading volume. We believe these results might be of great value to investors interested in cryptocurrencies and might instigate further research on this topic.

description: Kerr microresonators generate interesting and useful fundamental states of electromagnetic radiation through nonlinear interactions of continuous-wave (CW) laser light. Using photonic-integration techniques, functional devices with low noise, small size, low-power consumption, scalable fabrication, and heterogeneous combinations of photonics and electronics can be realized. Kerr solitons, which stably circulate in a Kerr microresonator, have emerged as a source of coherent, ultrafast pulse trains and ultra-broadband optical-frequency combs. Using the f-2f technique, Kerr combs support carrier-envelope-offset phase stabilization for optical synthesis and metrology. In this paper, we introduce a Kerr-microresonator optical clockwork based on optical-frequency division (OFD), which is a powerful technique to transfer the fractional-frequency stability of an optical clock to a lower frequency electronic clock signal. The clockwork presented here is based on a silicon-nitride (Si$_3$N$_4$) microresonator that supports an optical-frequency comb composed of soliton pulses at 1 THz repetition rate. By electro-optic phase modulation of the entire Si$_3$N$_4$ comb, we arbitrarily generate additional CW modes between the Si$_3$N$_4$ comb modes; operationally, this reduces the pulse train repetition frequency and can be used to implement OFD to the microwave domain. Our experiments characterize the residual frequency noise of this Kerr-microresonator clockwork to one part in $10^{17}$, which opens the possibility of using Kerr combs with high performance optical clocks. In addition, the photonic integration and 1 THz resolution of the Si$_3$N$_4$ frequency comb makes it appealing for broadband, low-resolution liquid-phase absorption spectroscopy, which we demonstrate with near infrared measurements of water, lipids, and organic solvents.

description: The Chinese American is a major part of the fast growing Asian population in the City of New York. This thesis focuses on the change in the spatial distribution of the Chinese Americans in city during 1970-­‐2010, whether the Chinese Americans are getting assimilated with other ethnic groups in this period and what kind of neighborhoods they tend to concentrate in. Using U.S. Census and PUMS data, I found that the cultural and ethnic ties may trump other factors in Chinese Americans’ location choices and they are not largely assimilated into the major population.

description: This report examines Indigenous community perspectives on the Arts & Culture District at UBC and on night time campus events. While there is a lack of academic literature on the topic, students from minority and non-dominant backgrounds are susceptible to negative experiences in higher education systems. A mixed-methods approach was utilized for this engagement, which took place in the First Nations House of Learning. An Indigenous medicine wheel was included in order to incorporate Indigenous epistemology as a method of welcoming and acknowledging our Aboriginal participants in a respectful way. The research uncovered a recognizable cohort of young students who live very close to campus and identify as Indigenous women. A majority of the participants were not familiar with the UBC Arts & Culture district, though some had attended events. Significant barriers for attending Arts & Culture events revolved around cost, content and inclusivity. Suggestions from participants for future events almost exclusively included Indigenous pop-culture and Indigenous arts-related content. If UBC wishes to host events that appeal to the Indigenous community, strong considerations should be given to the inclusion of Indigenous artists and cultural celebrations. This will provide an opportunity for an inclusive event that centralizes Indigeneity at UBC while still welcoming the broader UBC population to experience the strong cultural identity of First Nations Peoples.

description: Ptychopseustis sharporum sp. n.
Imago (fig. 34): Wingspan 10–13 mm. Head and appendages pale orange-brown, palpi porrect, maxillary palpus ¾ diameter of eye, labial palpus 1.5 × diameter of eye, antenna ⅔ length of forewing. Thorax and tegulae pale orangebrown. Forewing ground colour pale orange-brown, costa with various clusters of dark fuscous scales, antemedian fascia a dark fuscous line angled at costa then bent towards dorsum making an irregular line, an oblique fuscous discal spot, second fascia similar to first meeting costa at ⅔, a sequence of blackish dots before termen, fringe with dark brown line. Hindwing plain, paler than forewing. Legs whitish with a scattering of dark fuscous scales.
Male genitalia (fig. 71): Uncus a rounded triangle, gnathos reaching as far as uncus, heavily sclerotised near apex; valva broad at base then narrow with distal ¼ bent downwards; aedeagus partly curved, cornuti comprised of two serrate strips ¼ length of aedeagus.
Female genitalia (fig. 98): Ostium weak, about half width of ovipositor, antrum sclerotised, three times as long as wide, ductus widening gradually from antrum to corpus bursae, a sclerotised ring before corpus, corpus spherical much of the interior covered with minute spines.
Diagnosis: Distinguished from other species in the genus by its comparatively small size, and the oblique discal spot between the two fascias of the forewing; in the male genitalia by the shape of the distal part of the valva.
 Life history: has been reared from Capparis tomentosa.
Derivation: Named after A. and I. Sharp who reared the species.
Distribution: South Africa, Kenya.

On the existence of bright IR galaxies at z>2: tension between Herschel and SCUBA-2 results?

description: Recent derivations of the galaxy star formation rate density (SFRD) obtained from sub-millimetre (sub-mm) surveys (e.g., SCUBA-2) show a tension with previous works based on Herschel and multi-wavelength data. Some of these works claim that the SFRD derived by pushing the Herschel surveys beyond z~2 are incorrect. However, the current sub-mm surveys obtained from SCUBA-2 data and the methods used to construct the total infrared (IR) luminosity function (LF) and the SFRD could be affected by some limitations. Here we show how these limitations (i.e., selection bias and incompleteness effects) might affect the total IR LF, making the resulting dusty galaxy evolution of difficult interpretation. In particular, we find that the assumed spectral energy distribution (SED) plays a crucial role in the total IR LF derivation, moreover, we confirm that the long-wavelength (e.g., 850-micron) surveys can be incomplete against "warm" SED galaxies, and that the use of a wide spectral coverage of IR wavelengths is crucial to limit the uncertainties and biases.

Itemsets for Real-valued Datasets

description: Pattern mining is one of the most well-studied subfields in exploratory data analysis. While there is a significant amount of literature on how to discover and rank itemsets efficiently from binary data, there is surprisingly little research done in mining patterns from real-valued data. In this paper we propose a family of quality scores for real-valued itemsets. We approach the problem by considering casting the dataset into a binary data and computing the support from this data. This naive approach requires us to select thresholds. To remedy this, instead of selecting one set of thresholds, we treat thresholds as random variables and compute the average support. We show that we can compute this support efficiently, and we also introduce two normalisations, namely comparing the support against the independence assumption and, more generally, against the partition assumption. Our experimental evaluation demonstrates that we can discover statistically significant patterns efficiently.
