description: There has been tremendous recent progress in realizing topological insulator initiated by the proposal of Kane and Mele for the graphene system. They have suggested that the odd $Z_2$ index for the graphene manifests the spin filtered edge states for the graphene nanoribbons, which lead to the quantum spin Hall effect(QSHE). Here we investigate the role of the spin-orbit interaction both for the zigzag and armchair nanoribbons with special care in the edge geometry. For the pristine zigzag nanoribbons, we have shown that one of the $σ$ edge bands located near E=0 lifts up the energy of the spin filtered chiral edge states at the zone boundary by warping the $π$-edge bands, and hence the QSHE does not occur. Upon increasing the carrier density above a certain critical value, the spin filtered edge states are formed leading to the QSHE. We suggest that the hydrogen passivation on the edge can recover the original feature of the QSHE. For the armchair nanoribbon, the QSHE is shown to be stable. We have also derived the real space effective hamiltonian, which demonstrates that the on-site energy and the effective spin orbit coupling strength are strongly enhanced near the ribbon edges. We have shown that the steep rise of the confinement potential thus obtained is responsible for the warping of the $π$-edge bands.

Non-inclusive and non-deliberative : initiatives and referenda in comparative perspective
Creators: name: Ellis, Anthony
Publisher: name: University of British Columbia
Year: 2019

description: Initiatives and referenda may have deleterious effects on representative democracy in two ways. First, they may lead to outcomes that are not inclusive. Second, they undermine deliberation by providing binary choices. A most different systems methodology is used to explore the effect initiatives and referenda have on democracy in Washington State and Switzerland. It relies on the works of theorists of democratization, the existing comparative literature on referenda and initiatives, and contributions from scholars in fields outside political science such as biology and law. It concludes with a review of potential alternative institutions that reduce democratic deficits while mitigating the exclusionary risks posed by direct democratic mechanisms.

description: Magnetic p-n junction diodes are fabricated to investigate spin-polarized electron transport. The injection of spin-polarized electrons in a semiconductor is achieved by driving electrons from a ferromagnetic injector (Fe), into a bulk semiconductor (n-GaAs) via Schottky contact. For detection, a diluted magnetic semiconductor (p-GaMnAs) layer is used. Clear magnetoresistance was observed only when a high forward bias was applied across the p-n junction.

description: We observe the total filling factor νT=1 exciton condensate in independently contacted bilayer two-dimensional electron systems in samples with minute tunnel coupling. At balanced electron densities in the layers, we find for both drag and counter-flow current configurations, thermally activated transport with a monotonic increase of the activation energy for d/ℓB<1.65 with activation energies up to 0.4 K. In the imbalanced system the activation energies show a striking asymmetry around the balance point, implying that the gap to charge excitations is considerably different in the separate layers that form the bilayer condensate. This indicates that the measured activation energy is neither the binding energy of the excitons, nor their condensation energy.

description: Recent experiments on quantum Hall bilayers in the vicinity of total filling factor 1 (νT=1) have revealed many exciting observations characteristic of a superfluidic exciton condensate. We report on our experimental work involving the νT=1 exciton condensate in independently contacted bilayer two-dimensional electron systems. We observe previously reported phenomena as a zero-bias resonant tunneling peak, a quantized Hall drag resistivity, and in counter-flow configuration, the near vanishing of both ρxx and ρxy resistivity components. At balanced electron densities in the layers, we find for both drag and counter-flow current configurations, thermally activated transport with a monotonic increase of the activation energy for d/ℓB<1.65 with activation energies up to 0.4 K. In the imbalanced system the activation energies show a striking asymmetry around the balance point, implying that the gap to charge excitations is considerably different in the separate layers that form the bilayer condensate.

Scenario analysis using carbon budget modelling for alternative forest management strategies in Turkey : the case study of Arikaya
Creators: name: Satir, Enes
Publisher: name: University of British Columbia
Year: 2017

description: Increasing carbon stock in forests is fundamental for climate change mitigation. Forest carbon management can also play a critical role in keeping forests healthy, while addressing multiple wildlife and human needs. To fulfill this potential, forest management practices require an improved understanding of annual carbon stocks and carbon dynamics. However, this information is oftentimes not properly accounted for in forest management plans, particularly in the case of developing countries. This thesis focuses on a case study in Turkey to demonstrate the potential to enhance Turkish forest management plans by including carbon stock accounting. The Forest Planning Studios Atlas (FPS-Atlas) and the Carbon Budget Model of the Canadian Forest Service (CBM-CFS3) software programs were used to assess three alternative forest management scenarios in the case study. Carbon stock estimates for each scenario were compared to a baseline based on the current management plan. The first alternative scenario assumed an accelerating harvest rate over time, driven mainly by population growth. The second alternative scenario assumed rehabilitation of non-productive areas, a practice that has been gaining attention in Turkey over the last two decades. The third alternative scenario assumed the rehabilitation practices are combined with a low harvest flow. A carbon price analysis was conducted comparing the baseline with the third alternative scenario. Results showed that accelerating harvest can negatively affect the carbon stocks in a period of one hundred years. Rehabilitation, on the other hand, showed a positive impact on carbon sequestration potential when compared to the baseline after a hundred years. The rehabilitation scenario with low harvest flow showed promising results for international carbon trading. Overall, the methods used in this research proved useful to improve current forest managements strategies in Turkey, particularly in relation to climate change mitigation.

description: The study of spin photocurrents in (110)-grown quantum well structures is reported. The investigated effects comprise the circular photogalvanic effect and so far not observed circular photon drag effect. The experimental data can be described by an analytical expression derived from a phenomenological theory. A microscopic model of the circular photon drag effect is developed demonstrating that the generated current has a spin dependent origin.
The Disability Rights Critique of Technologies that Eliminate Human Genetic Variation

description: The development and use of an expanding range of medical technologies that yield genetic information about embryos and fetuses has raised ethical questions about whether and how this increasingly routine set of practices discriminates against people with disabilities. A conversation in the form of academic articles and public media offers explications and critiques about the social and moral harms human gene editing and prenatal genetic testing and the selective reproduction practices it prompts bring to humanity. These purported harms range from increased social inequity—at the very least—to structural and individual violence—at the very most. This collection suggests that conversations about these technologies have changed over time and also reflects the varied communities engaged in those conversations over time and across social locations. The collection thus focuses on the health humanities in the broadest sense. This means that the data, evidence, and knowledge it gathers come from the lives of individuals, families, and human communities who live with disabilities and illnesses, not from medical-scientific or clinical data. The stories in the final section of this collection present a range of lived experience that suggests both the potential benefits and harms genetic disabilities bring over lifespans to individual people, their families, and their communities. These stories offer narrative data about distinctive human lives that may be more textured than the predominant measurement data that scientific medicine provides about human lives. The collection thus brings a humanistic, narrative, and phenomenological focus to the disability rights critique of technologies that aim to eliminate human genetic variation. It aims to open up perceptions about the ethics of gene editing and selection practices beyond the voices and perspectives of medical-scientific experts. As such, the collection responds to the perpetual call for broad public conversations and involvement from diverse stakeholders in decisions about the regulation, use, and development of genetic screening and intervention technologies. The literature in this collection reflects three conversation sites about the ethics of human gene editing and prenatal genetic testing and selective reproduction: disability rights, culture, and justice analyses of the harms of eliminating the human variations we think of as disabilities; healthcare ethics perspectives on the possible ethical harms of genetic testing and selective termination; public facing narratives about people living with a wide range of genetic disabilities in various relationships across life stages.

description: The release of conduction-band electrons from a metal surface by a sub-femtosecond extreme ultraviolet (XUV) pulse, and their propagation through the solid, provokes a dielectric response in the solid that acts back on the photoelectron wave packet. We calculated the (wake) potential associated with this photoelectron self-interaction in terms of bulk and surface plasmon excitations and show that it induces a considerable, XUV-frequency-dependent temporal shift in laser-streaked XUV photoemission spectra, suggesting the observation of the ultrafast solid-state dielectric response in contemporary streaked photoemission experiments.

At small magnetic fields we observe a linear increase of Δ with the magnetic field. The slope of Δ vs. B allows us to directly extract the composite fermion g-factor.
Deformability-based separation and single-cell sequencing of circulating tumor cells in prostate cancer
Creators: name: Park, Emily Sunyoung
Publisher: name: University of British Columbia
Year: 2019

description: Circulating tumor cells (CTCs) are malignant cells shed from a primary tumor into the bloodstream, where they have the potential to seed metastases responsible for >90% of all cancer related deaths. CTCs are particularly interesting for prostate cancer because metastases occur predominantly bone tissue, which makes biopsies difficult and low yielding. Since CTCs are accessible from peripheral blood, these cells represent a potential source of highly relevant tumor materials, which could be used to reveal new biomarkers for monitoring disease progression and evaluating drug efficacy. A key challenge in CTC isolation and characterization has been their extreme rarity in blood and their cell-to-cell heterogeneity. Both of these issues suggest the need to develop robust methods to isolate and analyze individual CTCs. This dissertation presents a new workflow to isolate, extract, and sequence single CTCs from patients with metastatic prostate cancer. Initially, we investigated the morphology of CTCs from patients with prostate cancer, and observed that CTCs and leukocytes were similar in size, but distinct in nucleus-to-cytoplasm ratio, which suggests the potential to separate CTCs based on deformability. Based on this result, a microfluidic device that separates CTCs based on cell deformability, as well as an accompanying analytical pipeline to identify CTCs using immunofluorescence, were developed, optimized, and tested. This workflow was used to successfully enumerate CTCs from 20 patients with metastatic castrate resistant prostate cancer, as well as 25 patients with localized prostate cancer. For the former cohort, we compared our process against existing technology and demonstrated 25× greater yield. We then developed a process to isolate single CTCs using laser capture microdissection for genome sequencing. Using this process, we enriched and isolated 30 single CTCs from 3 patients with metastatic prostate cancer, and sequenced 5 of these single CTCs from a patient with matched cell-free DNA. The sequencing data confirmed the presence of major driver mutations, including PTEN and TP53, as well as heterogeneous characteristics of individual CTCs. These results demonstrate the potential of our single cell sequencing workflow to discover clinically relevant mutations from single CTCs that may aid in monitoring disease progression and guiding treatment.

description: The existence of photonic stop bands in the self-assembled arrangement of pores in porous anodic alumina structures is investigated by means of rigorous 2D finite- difference time-domain calculations. Self-assembled porous anodic alumina shows a random distribution of domains, each of them with a very definite triangular pattern, constituting a quasi-random structure. The observed stop bands are similar to those of photonic quasicrystals or random structures. As the pores of nanoporous anodic alumina can be infiltrated with noble metals, nonlinear or active media, it makes this material very attractive and cost-effective for applications including inhibition of spontaneous emission, random lasing, LEDs and biosensors.

description: Relaxation of single defects in a nanometer-sized resonator is observed by coupling surface acoustic waves to a freely suspended beam. The surface waves act on the resonator as driving forces being able to modify the internal friction in the beam. In analogy to classical experiments on internal friction in macroscopic samples, we perform frequency, amplitude, and temperature-dependent experiments on the nano resonator and find a scenario which is consistent with the observation of single-defect relaxation.

description: We propose and implement a nondestructive measurement that distinguishes between two-electron spin states in a quantum dot. In contrast to earlier experiments with quantum dots, the spins are left behind in the state corresponding to the measurement outcome. By measuring the spin states twice within a time shorter than the relaxation time T1, correlations between the outcomes of consecutive measurements are observed. They disappear as the wait time between measurements becomes comparable to T1. The correlation between the postmeasurement state and the measurement outcome is measured to be ∼90% on average.

description: I present some applications of geometric flows in string theory and gravity. In some circumstances time evolution in string theory can be approximately identified with Ricci-flow parametric evolution of spatial sections. In four dimensions, homogeneous, self-dual, gravitational instantons of general relativity evolve in time exactly as geometric flows of homogeneous three-manifolds. For non-relativistic versions of gravity, this property persists in any dimension, under the assumption of detailed-balance condition.

description: An electron beam ion trap (EBIT) is used to measure extreme ultraviolet spectra between 10 nm and 25 nm from highly-charged ions of tungsten with an open 3d shell (W XLVIII through W LVI). We found that almost all strong lines are due to the forbidden magnetic-dipole (M1) transitions within $3d^n$ ground configurations. A total of 37 spectral lines are identified for the first time using detailed collisional-radiative (CR) modeling of the EBIT spectra. A new level-merging scheme for compactification of rate equations is described. The CR simulations for Maxwellian plasmas show that several line ratios involving these M1 lines can be used to reliably diagnose temperature and density in hot fusion devices.

description: The spectra of O and B supergiants are known to be affected by a significant form of extra line broadening (usually referred to as macroturbulence) in addition to that produced by stellar rotation. Recent analyses of high resolution spectra have shown that the interpretation of this line broadening as a consequence of large scale turbulent motions would imply highly supersonic velocity fields in photospheric regions, making this scenario quite improbable. Stellar oscillations have been proposed as a likely alternative explanation. As part of a long term observational project, we are investigating the macroturbulent broadening in O and B supergiants and its possible connection with spectroscopic variability phenomena and stellar oscillations. In this letter, we present the first encouraging results of our project, namely firm observational evidence for a strong correlation between the extra broadening and photospheric line-profile variations in a sample of 13 supergiants with spectral types ranging from O9.5 to B8.

description: For understanding the origin of life, it is essential to explain the development of a compartmentalized structure, which undergoes growth and division, from a set of chemical reactions. In this study, a hypercycle with two chemicals that mutually catalyze each other is considered in order to show that the reproduction of a protocell with a growth-division process naturally occurs when the replication speed of one chemical is considerably slower than that of the other chemical. It is observed that the protocell divides after a minority molecule is replicated at a slow synthesis rate, and thus, a synchrony between the reproduction of a cell and molecule replication is achieved. The robustness of such protocells against the invasion of parasitic molecules is also demonstrated.

Photoprotection of wood using metal acetylacetonates
Creators: name: Zhu, Yuner
Publisher: name: University of British Columbia
Year: 2019

description: Wood is a versatile material with a pleasant appearance that is widely used in architectural and interior applications. However, wood (including clear-coated wood) undergoes degradation when it is exposed outdoors. Wood can be protected from surface photodegradation (weathering) using reactive metal ions that are able to cross-link wood’s molecules and create complexes that are resistant to photodegradation. Metal acetylacetonates are coordination complexes of metal ions and the acetylacetonate anion. Metal acetylacetonates are used by industry to cross-link chemicals, and they have also been used as photostabilizers for polymers. One study has shown that titanium acetylacetonate can reduce the photodegradation of radiata pine veneers exposed to natural weathering. My general hypothesis is that metal acetylacetonates will be able to protect wood from photodegradation on their own or in combination with other protective systems, including clear finishes, oils and UV absorbers. I compared the photoprotective effects of six metal acetylacetonates on yellow cedar veneers and clear-coated yellow cedar and Scots pine panels. I found that the ability of metal acetylacetonates to photostabilize yellow cedar veneers varies depending on the metal in the coordination complex. Nickel, manganese, titanium and iron acetylacetonate were more effective than cobalt acetylacetonate at photostabilizing wood, based on the different measures I used to assess the degradation of weathered veneers. Iron acetylacetonate was more effective at photostabilizing lignin in weathered veneers than the other metal acetylacetonates. Manganese and titanium acetylacetonate had some positive effects on the performance of a clear polyurethane coating on Scots pine and particularly yellow cedar panels exposed to artificial accelerated weathering. Oils when combined with titanium acetylacetonate provided additional protection to wood surfaces, most notably water repellency, but the oils had negative effects (mould growth) on the appearance of panels exposed to natural weathering. I conclude that metal acetylacetonates can photostabilize wood surfaces and improve the performance of a clear polyurethane coating on wood, However, the effectiveness of metal acetylacetonates depends on the metal in the coordination complex and the wood species that are treated with the acetylacetonate. Finally, I conclude that metal acetylacetonates have potential as protective treatments, particular photoprotective primers for coatings.

description: Low-temperature transport measurements were performed on a two-terminal Aharonov–Bohm interferometer with one Coulomb-blockaded quantum dot (QD) embedded in each of the two interfering paths. Layered local anodic oxidation of the Ga[Al]As heterostructure and a thin titanium top gate give full tunability of the inter-dot tunnel coupling from purely capacitive to the QD molecule regime and of the tunnel coupling of the dots to the Aharonov–Bohm ring leads. Aharonov–Bohm oscillations are observed in the cotunneling regime far away from conductance resonances. This indicates that transport in the cotunneling regime is at least partially phase coherent. The phase of the Aharonov–Bohm oscillations is monitored as one crosses conductance resonances around a degeneracy point in the charge stability diagram. The phase in this two-terminal device is constant in the cotunneling regime between conductance resonances.

description: In competitions involving many participants running many races the final rank is determined by the score of each participant, obtained by adding its ranks in each individual race. The "Statistical Curse of the Second Half Rank" is the observation that if the score of a participant is even modestly worse than the middle score, then its final rank will be much worse (that is, much further away from the middle rank) than might have been expected. We give an explanation of this effect for the case of a large number of races using the Central Limit Theorem. We present exact quantitative results in this limit and demonstrate that the score probability distribution will be gaussian with scores packing near the center. We also derive the final rank probability distribution for the case of two races and we present some exact formulae verified by numerical simulations for the case of three races. The variant in which the worst result of each boat is dropped from its final score is also analyzed and solved for the case of two races.

description: We demonstrate experimentally a read-out method that distinguishes between two-electron spin states in a quantum dot. This scheme combines the advantages of the two existing mechanisms for spin-to-charge conversion with single-shot charge detection: a large difference in energy between the two states and a large difference in tunnel rate between the states and a reservoir. As a result, a spin measurement fidelity of 97% was achieved, which is much higher than previously reported fidelities.

description: We present measurements of the magnetoresistance of a two-dimensional electron gas (2DEG) under continuous microwave as a function of the irradiation frequency. In a previous work by Simovič et al. [Phys. Rev. B 71 (2005) 233303], the magnetoresistance under microwave was shown to be modulated by oscillations of large amplitude that are periodic with magnetic field, their period and phase depending strongly on the electron density. Here we show that the phase and the amplitude of the microwave-induced oscillations also depend on the frequency of irradiation and the sign of the magnetic field.

description: Low-temperature transport experiments on a quantum point contact under the influence of a scanning gate are reported. The scanning gate is the metallic tip of a scanning force microscope operating at a temperature of 300 mK. In particular, the influence of the scanning tip on conductance resonances observed in the gate-characteristics of the point contact is studied. The strongest conductance resonances appear to be related to the local potential within the channel of the point contact. As a consequence, the point contact with its conductance resonances can be used as a sensor for the local tip-induced potential.

description: With baureka.online the Chair of Architectural History at RWTH Aachen University, the Department of Building History and History of Urban Development at the TU Berlin and FIZ Karlsruhe – Leibniz Institute for Information Infrastructure are in the process of setting up a subject-specific digital portal that will allow  an effective search, secure archiving and sustainable publication of research data for researchers and practitioners from the field of Building Archaeology and its related disciplines.
Building Archaeology studies built structures, their genesis and their further development in a historical perspective. The results of these studies are large volumes of heterogeneous data in a wide variety of different formats. Despite the amount of data generated in the course of the respective projects there is still a lack of portals and platforms to archive, publish, search and exchange these data.
The goal of baueka.online therefore is to provide digital architectural documentation to a wider range of players concerned with historic buildings and to promote synergies between scholarly research, heritage preservation and architectural practice by improving the findability and reusability of research data.
The development of the platform started in 2021 and is being funded by the DFG.
Our poster will illustrate baureka.online, its single components and their independency. It will also display how baureka.online will support the digital transformation in the field of Building Archaeology and establish the format of research data publications.

baureka.storage will provide a repository for storing and publishing primary research data with DOIs.
baureka.index will establish a catalogue of published research data with cross-institutional references. This will allow users to search for data published in baureka.online but also for information about data in other sources.
A newly-developed metadata schema will make it possible to describe research data with subject specific criterias.
baureka.online will also ensure that the published data is findable and reusable and complies with FAIR principles.
The poster will also present the intentions for the second funding period:

With baureka.publications, a data journal will be integrated into the portal, enabling building archaeologists to publish selected data sets comprehensively and in an appropriate manner.
Mask formulas for cograssmannian Kazhdan-Lusztig polynomials

description: We give two contructions of sets of masks on cograssmannian permutations that can be used in Deodhar's formula for Kazhdan-Lusztig basis elements of the Iwahori-Hecke algebra. The constructions are respectively based on a formula of Lascoux-Schutzenberger and its geometric interpretation by Zelevinsky. The first construction relies on a basis of the Hecke algebra constructed from principal lower order ideals in Bruhat order and a translation of this basis into sets of masks. The second construction relies on an interpretation of masks as cells of the Bott-Samelson resolution. These constructions give distinct answers to a question of Deodhar.

Spatiotemporal patterns and reliability of bobcat and Canada lynx occurrence records in British Columbia

Publisher: name: University of British Columbia

description: Understanding the distribution of a species is imperative for proper management and conservation to occur, especially in the wake of climate change and other biotic and abiotic changes that are currently occurring across the globe. Numerous species are shifting their ranges in response to these changes; tracking these shifts is the first step in conserving current and future habitats. Provincial or state-wide records, as well as citizen science, can be used to estimate broad-scale distributions, whereas camera trapping has become a common tool for detecting species at smaller scales. However, cryptic and elusive species such as mesocarnivores are difficult to monitor. Here, I use bobcats (Lynx rufus) and Canada lynx (L. canadensis) in British Columbia, Canada, as a case study to examine the data sources available for mapping mesocarnivore distributions, use those data to assess whether bobcat and lynx distributions have undergone any shifts over the past century, and determine whether these very similar-looking species can be reliably identified from camera images. I estimated the distributions of bobcats and lynx in BC using five independent data sources. Trapping records, hunting records, vehicle-kill records, trapper surveys that I distributed, and images that I solicited from the public all indicated that bobcats were restricted to southern BC, whereas lynx occurred throughout most of the interior of the province. I used trapping records and trapper surveys to determine whether bobcats or lynx have shifted their range in BC; these data suggest that distributions have remained stable over the past century. Lastly, I measured agreement among experts in classifying images of bobcats and lynx, and revealed that even experts find it difficult to distinguish between bobcats and lynx from camera images; agreement among experts in their classifications of the images was poor, and experts were inconsistent when asked to reclassify images weeks later.

description: Possible phase transition of strongly interacting matter from hadron to a Quark-Gluon Plasma (QGP) state have in the p ast received considerable interest. It has been suggested that this problem might be treated by percolation theory. Th e Color String Percolation Model (CSPM) is used to determine the equation of state (EOS) of the QGP produced in central Au-Au collisions at RHIC energies. The bulk thermodynamic quantities- energy density, entropy density and t he sound velocity- are obtained in the framework of CSPM. It is shown that the results are in excellent agreement with the recent lattice QCD calculations(LQCD).

description: The generation, manipulation and detection of spin-polarized electrons in low-dimensional semiconductors are at the heart of spintronics. Pure spin currents, that is, fluxes of magnetization without charge current, are quite attractive in this respect. A paradigmatic example is the spin Hall effect, where an electrical current drives a transverse spin current and causes a non-equilibrium spin accumulation observed near the sample boundary1, 2. Here we provide evidence for an another effect causing spin currents which is fundamentally different from the spin Hall effect. In contrast to the spin Hall effect, it does not require an electric current to flow: without bias the spin separation is achieved by spin-dependent scattering of electrons in media with suitable symmetry. We show, by free-carrier absorption of terahertz (THz) radiation, that spin currents flow in a wide range of temperatures. Moreover, the experimental results provide evidence that simple electron gas heating by any means is already sufficient to yield spin separation due to spin-dependent energy-relaxation processes.
