Impact of the COVID-19 pandemic on access to cancer surgery : analysis of surgical wait times in British Columbia, Canada
Creators: name: Shojaei, Delaram
Publisher: name: University of British Columbia
Year: 2022

description: Background: As COVID-19 spread, efforts were made to preserve hospital resources to prepare for the anticipated surge of COVID-19 patients. However, the relationship between COVID-19 hospitalizations and access to cancer surgery is unknown. In this project, we analyze the impact of COVID-19 patient volume and wait time for cancer surgery. We also investigate the effect on wait time for non-cancer surgery, the number of surgeries performed, and the number of patients waiting for surgery. Methods: We conducted a population-based retrospective study using electronic databases and registries and examined regional surgical wait times and COVID-19 patient volumes to produce a qualitative analysis. The regional volume of surgery and patients waiting for surgery were also analysed for cancer and non-cancer diagnosis groups. Results: Changes in regional, weekly median wait time for priority and other cancer surgery were independent of COVID-19 patient volume. In the first phase of the pandemic, volume of patients and wait time for urgent surgery is shortened while volume of patients and wait time for non-urgent surgery is extended. In the second phase, for all diagnosis groups, wait time recovers. In the third phase, volume of patients waiting for all surgeries increases. Conclusion: Regional COVID-19 patient hospitalization in critical and non-critical care did not affect cancer surgery access. If further supported by future studies, cancellation of non-urgent surgeries as mandated by provincial governments, and institutional actions in upholding the efficiency of the health system are likely to act as influential factors in access to cancer surgery.

description: The United States presently finds itself standing at a remarkable historical juncture. As the world's only "remaining superpower," it enjoys the benefit of military superiority, economic prosperity, and vast cultural influence. Yet despite its seeming superiority to other nations -or, perhaps, in spite of it- the future is not necessarily secured for the United States. While Americans may be able to take American power for granted, there is a general sense that the United States is either at or near the apex of its influence; that, as Samuel Huntington has argued, while the U.S. will remain strong, its strength will decline relative to that of other civilizations.

description: The lowest-lying glueball masses are computed in SU($N$) gauge theory on a spacetime lattice for constant value of the lattice spacing $a$ and for $N$ ranging from 3 to 8. The lattice spacing is fixed using the deconfinement temperature at temporal extension of the lattice $N_T = 6$. The calculation is conducted employing in each channel a variational ansatz performed on a large basis of operators that includes also torelon and (for the lightest states) scattering trial functions. This basis is constructed using an automatic algorithm that allows us to build operators of any size and shape in any irreducible representation of the cubic group. A good signal is extracted for the ground state and the first excitation in several symmetry channels. It is shown that all the observed states are well described by their large $N$ values, with modest ${\cal O}(1/N^2)$ corrections. In addition spurious states are identified that couple to torelon and scattering operators. As a byproduct of our calculation, the critical couplings for the deconfinement phase transition for N=5 and N=7 and temporal extension of the lattice $N_T=6$ are determined.

Exploring the vacuum structure of gravitationally induced neutrino masses

description: In this work, we explore the proposed mechanism in which the gravitational $θ$ anomaly generates neutrino masses. We highlight that the leading renormalizable interactions of the neutrino condensate forbid the possibility of generating hierarchical masses consistent with observation. This conclusion still holds when Standard Model loop corrections are accounted for. We show that higher-dimensional operators can alleviate this problem. The higher-dimensional operators could be generated from the gravitational anomaly itself, but there is no clear way to know without a deeper understanding of the low-energy description of this mechanism. Because of that, we explore the possibility of new particles generating neutrino mass splittings. We show that both new particles that alter the scalar potential of the condensate or new particles in loops for the neutrino self-energy can solve this problem.

description: We relate the problem of irreversibility of entanglement with the recently defined measures of quantum correlation - quantum discord and one-way quantum deficit. We show that the entanglement of formation is always strictly larger than the coherent information and the entanglement cost is also larger in most cases. We prove irreversibility of entanglement under LOCC for a family of entangled states. This family is a generalization of the maximally correlated states for which we also give an analytic expression for the distillable entanglement, the relative entropy of entanglement, the distillable secret key and the quantum discord.

description: Structural moiré superstructures arising from two competing lattices may lead to unexpected electronic behavior, such as superconductivity or Mottness. Most investigated moiré heterostructures are based on van der Waals (vdW) materials, as strong interface interactions typically lead to the formation of strained films or regular surface reconstructions. Here we successfully synthesize ultrathin Sb films, that are predicted to show thickness-dependent topological properties, on semi-insulating InSb(111)A. Despite the covalent nature of the substrate surface, we prove by scanning transmission electron microscopy (STEM) that already the first layer of Sb atoms grows completely unstrained, while azimuthally aligned. Rather than compensating the lattice mismatch of -6.4% by structural modifications, the Sb films form a pronounced moiré pattern as we evidence by scanning tunneling microscopy (STM) topography up to film thicknesses of several bilayers. Our model calculations based on density functional theory (DFT) assign the moiré pattern to a periodic surface corrugation. In agreement with DFT predictions, irrespective of the moiré modulation, the topological surface state known on thick Sb film is experimentally confirmed to persist down to low film thicknesses, and the Dirac point shifts towards lower binding energies with decreasing Sb thickness.

description: The consumers are considered to play one of the most significant roles in the district heating transition process towards the 4th generation.  Unfortunately, the lack of information and widespread consumer ignorance of interconnections and dependencies in the district heating system can lead to a situation where consumers are not interested in the development of the district heating system, or might even choose other heat sources. One of the possible solutions to provide information and educate consumers is a user-friendly, simplified mobile app that can show actual heat consumption structure, provide the possibility to compare the district heating supply with other heat supply solutions and provide information on how consumer behaviour affects the district heating system and how the district heating system transition towards the 4th generation will change the primary energy consumption and CO2 emissions. In this article, the authors present the concept and algorithm of a DHS promo mobile app that will be used at the national level in Estonia, that will allow consumers even with an insufficient amount of data available to each apartment/building owner to receive comprehensive information about the existing DHS and analyse how DHS improvements will affect the fuel mix and consumption amount required for heat supply per consume.

description: The Landau free-energy of a compound that benefits from a linear coupling of an electric field and a magnetic field includes a product of the two fields, one polar and time-even and one axial and time-odd. In ME compounds, expectation values of some atomic magnetic tensors are invariant with respect to anti-inversion. An invariance shared by the Dirac monopole (an element of charge allowed in Maxwell's equations that has not been observed) and a Zeldovich anapole, also known as a Dirac dipole. From the science of materials perspective, it has been established that Dirac multipoles contribute to the diffraction of x-rays and neutrons. We identify Dirac monopoles in bulk magnetic properties of iron tellurate (Fe2TeO6) and a spin ladder (SrFe2S2O). Both cited compounds present a simple antiferromagnetic configuration of axial dipoles, and their different magnetic crystal classes allow a linear ME effect. However, the Kerr effect is symmetry allowed in the spin ladder and forbidden in iron tellurate. Anapoles are forbidden in iron tellurate and allowed in the spin ladder compound, a difference evident in diffraction patterns fully informed by symmetry. More generally, we identify a raft of Dirac multipoles, and axial multipoles beyond dipoles, visible in future experiments using standard techniques with beams of neutrons or x-rays tuned in energy to an iron atomic resonance. ME invariance imposes a phase relationship between nuclear (charge) and magnetic contributions to neutron (x-ray) diffraction amplitudes. In consequence, intensities of Bragg spots in an x-ray pattern do not change when helicity in the primary beam is reversed. A like effect occurs in the magnetic diffraction of polarized neutrons.
A dynamical systems study of the inhomogeneous Lambda-CDM model

description: We consider spherically symmetric inhomogeneous dust models with a positive cosmological constant, $Λ$, given by the Lemaitre-Tolman-Bondi metric. These configurations provide a simple but useful generalization of the Lambda-CDM model describing cold dark matter (CDM) and a Lambda term, which seems to fit current cosmological observations. The dynamics of these models can be fully described by scalar evolution equations that can be given in the form of a proper dynamical system associated with a 4-dimensional phase space whose critical points and invariant subspaces are examined and classified. The phase space evolution of various configurations is studied in detail by means of two 2-dimensional subspaces: a projection into the invariant homogeneous subspace associated with Lambda-CDM solutions with FLRW metric, and a projection into a subspace generated by suitably defined fluctuations that convey the effects of inhomogeneity. We look at cases with perpetual expansion, bouncing and loitering behavior, as well as configurations with "mixed" kinematic patters, such as a collapsing region in an expanding background. In all cases, phase space trajectories emerge from and converge to stable past and future attractors in a qualitatively analogous way as in the case of the FLRW limit. However, we can identify in both projections of the phase space various qualitative features absent in the FLRW limit that can be useful in the construction of toy models of astrophysical and cosmological inhomogeneities.

description: A fully algebraic general approach is developed to treat the pairs emission and absorption in the presence of some uniform external background field. In particular, it is shown that the pairs production and annihilation operators, together with the pairs number operator, do actually fulfill the SU(2) functional Lie algebra. As an example of application, the celebrated Schwinger formula is consistently and nicely recovered, within this novel approach, for a Dirac spinor field in the presence of a constant and homogeneous electric field in four spacetime dimensions.

title: "With a Joint View to the Entertainment and Information of Mankind:" The Development of Eighteenth Century British Tourism
Creators: name: Wegener, Sarah Caroline
Publisher: name: Utah State University
Year: 2003

description: Tourism in its current form did not exist until the nineteenth century with the emergence of the railroads. However, crucial developments in mid-eighteenth century Great Britain started the process leading to modem tourism. Over the course of the eighteenth century, the concept behind tourism expanded and its motivations were transformed. Early eighteenth century tourism was associated with wealth and class. United in their various interests by a common desire, tourists sought experience to assist them in their future life. By the end of the century a shift had taken place, and tourism took on a new face. Though this form of travel did not die until the twentieth century, it lost its position as the sole model of travel. Modem tourism is a product of late eighteenth century theories and practices.

description: The revamping of existing high temperature district heating systems with low temperature solutions will ensure a better usage of primary energy thanks to the reduction of thermal losses through the networks and to the possibility of use low grade enthalpy heat for the scope, including renewables and waste heat. However, several criticalities are present that make the evolution from the 3rd to the 4th generation of district heating not immediate.


The paper aims to identify general technological and non-technological barriers in the revamping of traditional district heating networks into low temperature ones, with a particular focus on the Italian framework. Possible solutions are suggested, including also relevant advices for decision makers. Furthermore, the paper analyses how the possible solutions required for the up-grade of the existing district heating network can be classified through the Analytic Hierarchy Process (AHP) to prioritize the best resulting ones for more advanced evaluations.

description: The paper presents a modelling framework that may be used to plan the integration of large-scale HPs in district heating (DH) areas. By use of the methodology both optimal HP capacities to be installed and optimal choice of heat source to be used during the year are identified by minimizing total cost of ownership including investment and operational costs. The modelling framework uses mixed-integer linear programming and hourly calculations over one year. Seasonal variations of the heat source temperatures, capacity limitations and HP coefficient of performance as well as technical constraints were taken into account.


The DH network of Tallinn, Estonia, was used as a case study. Six different heat source types were identified for 13 potential locations of large-scale HPs.


The results showed that the integration of large-scale HPs in the DH network of Tallinn is economically feasible. It was found that 122 MW HP capacity could be installed without compromising the operation of sustainable base load units. The heat sources needed for obtaining this solution were sewage water, river water, ambient air, seawater and groundwater. It was further shown that the Lorenz efficiency depends on the variations of heat source temperatures.

description: To work with lowering the system temperatures in district heating (DH) grids is an important factor for system efficiency. Lower system temperatures are related to for example heat losses and production unit efficiency. One obstacle to lower supply temperatures are so called bottlenecks in DH networks. Bottlenecks are areas in the DH network that have very low differential pressure, which makes it difficult to supply them with enough heat. There are many possible solutions to bottlenecks, but presently the decision making process most often do not include all possible bottleneck solutions and also often do not include all important factors affecting the outcome. The aim of this study is to propose a structured and general modus operandi, in order to find the best bottleneck solution for a specific situation. In this study we conducted analyses of previous bottleneck studies, workshops and interviews. The results show a decision making process developed to be a tool when choosing a bottleneck solution. Coupled to the decision making process, a summary of advantages and disadvantages for different factors and bottlenecks solutions is presented, as well as a real case where the decision making process is used.

description: We design, simulate, and experimentally characterize an acoustic metasurface comprising of a 1D array of open, sound-hard, cavities, modulated with beyond-nearest-neighbor (BNN) couplings in the form of additional connecting cavities embedded beneath the surface. The hidden complex structure is realized readily with additive manufacturing techniques (3D printing). The dispersive properties of the supported localized acoustic surface waves are influenced by competing power-flow channels provided by the BNN couplings, that generate extrema in the dispersion spectra within the first Brillouin zone. The structure supports negatively dispersing 'backwards' waves that we experimentally verify. Such structures thereby provide a route to enhanced acoustic sensing by acoustic metasurfaces.

Stiefel-Whitney Numbers for Singular Varieties

description: This paper determines which Stiefel-Whitney numbers can be defined for singular varieties compatibly with small resolutions. First an upper bound is found by identifying the F_2-vector space of Stiefel-Whitney numbers invariant under classical flops, equivalently by computing the quotient of the unoriented bordism ring by the total spaces of RP^3 bundles. These Stiefel-Whitney numbers are then defined for any real projective normal Gorenstein variety and shown to be compatible with small resolutions whenever they exist. In light of Totaro's result [Tot00] equating the complex elliptic genus with complex bordism modulo flops, equivalently complex bordism modulo the total spaces of twisted(CP^3) bundles, these findings can be seen as hinting at a new elliptic genus, one for unoriented manifolds.

description: Haros graphs have been recently introduced as a set of graphs bijectively related to real numbers in the unit interval. Here we consider the iterated dynamics of a graph operator $\cal R$ over the set of Haros graphs. This operator was previously defined in the realm of graph-theoretical characterisation of low-dimensional nonlinear dynamics, and has a renormalization group (RG) structure. We find that the dynamics of $\cal R$ over Haros graphs is complex and includes unstable periodic orbits or arbitrary period and non-mixing aperiodic orbits, overall portraiting a chaotic RG flow. We identify a single RG stable fixed point whose basin of attraction is the set of rational numbers, associate periodic RG orbits with (pure) quadratic irrationals and aperiodic RG orbits with (non-mixing) families of non-quadratic algebraic irrationals and trascendental numbers. Finally, we show that the entropy gradients inside periodic RG orbits are constant. We discuss the possible physical interpretation of such chaotic RG flow and speculate on the entropy-constant periodic orbits as a possible confirmation of a (quantum field-theoretic) $c$-theorem applied inside the invariant set of a RG flow.
Distinguishing Non-Standard Interaction and Lorentz Invariance Violation at Protvino to Super-ORCA experiment

description: As the two phenomena, non-standard interaction (NSI) in neutrino propagation and Lorentz invariance violation (LIV) modify the Hamiltonian of neutrino oscillation in a similar fashion, it is very difficult to distinguish these two effects. The only difference between them lies in the fact that NSI depends on the matter density, whereas LIV is independent of the earth matter effect. Therefore for a fixed baseline experiment, where matter density is constant, the theories describing NSI and LIV are exactly equivalent. However, as the present and future bounds of the NSI and LIV parameters are not equivalent, one can distinguish these two scenarios in the long-baseline neutrino experiments depending on their statistics with respect to the present and future bounds of these parameters. In this paper, we attempt to differentiate between LIV and NSI in the context of DUNE and P2SO, as these two future experiments are believed to be sensitive to the strongest matter effect and will have very large statistics. Taking LIV in the data and NSI in theory, our results show that, indeed it is possible to have good discrimination between LIV and NSI. The best separation between LIV and NSI at $3 σ$ C.L. is achieved for the parameter $a_{μμ}$ with P2SO. In this case, the value of LIV parameter for which separation is possible, lies within its future bound, if one considers the value of NSI parameter to be constrained by the present experiments. Between DUNE and P2SO, the latter has better sensitivity for such discrimination.

description: Vertical van der Waals heterostructures of semiconducting transition metal dichalcogenides realize moiré systems with rich correlated electron phases and moiré exciton phenomena. For material combinations with small lattice mismatch and twist angles as in MoSe$_2$-WSe$_2$, however, lattice reconstruction eliminates the canonical moiré pattern and instead gives rise to arrays of periodically reconstructed nanoscale domains and mesoscopically extended areas of one atomic registry. Here, we elucidate the role of atomic reconstruction in MoSe$_2$-WSe$_2$ heterostructures synthesized by chemical vapor deposition. With complementary imaging down to the atomic scale, simulations, and optical spectroscopy methods we identify the coexistence of moiré-type cores and extended moiré-free regions in heterostacks with parallel and antiparallel alignment. Our work highlights the potential of chemical vapor deposition for applications requiring laterally extended heterosystems of one atomic registry or exciton-confining heterostack arrays.

title: Rational utilisation of a common resource by multiple agents
Creators: name: Haider, Alexander
Publisher: name: TU Wien
Year: 2013

description: The behaviour of multiple agents who utilise one common resource will be investigated in this thesis, where different growth models for the resource are taken into account. The agents' utility depends on the stock of the resource, their extraction rate and their technological level, which can be increased with investments. The influence of how much one agent is future-oriented will be the key point for the optimal control strategies. The main focus is on the one agent problem, how the optimal solution of this one agent changes if a second agent is introduced, and at last, how the optimal outcome of these two agents can be increased, if instead of a full competition on the market the agents mutually agree on a certain commitment strategy in order to jointly extract the resource optimally. It will turn out that in any case a certain commitment is of benefit for both agents and will increase their output compared to the non-commitment strategy. Solutions will be obtained by applying Pontryagins Maximum Principle and the concept of Nash equilibria in a differential game setup and the obtained numerical solutions for the two agent cases are explicitly given and analysed.

title: Thresholds in the optimal treatment of infected heterogeneous populations
Creators: name: Hollick, Iris
Publisher: name: TU Wien
Year: 2013

description: This thesis investigates thresholds in an epidemic, heterogenenous model and how they are in uenced by the heterogeneity. First aepidemical models is introduced, where it could be optimal to treat at a maximal possible level or not to treat at all, depending on the particular parameters and initial state. Therefore an homogeneous epidemiological model is presented, whose heterogeneity is introduced with respect to the time the individual is already infected. Afterwards the optimal control problem is introduced for a restricted, constant control variable. The fourth section presents thresholds, rstly in a homogeneous version of the heterogeneous model. Based on these results, heterogeneity is introduced to the model and it is investigated how the thresholds are changing for dierent distribution functions. Finally a sensitivity analysis is conducted with respect to the infectivity of the disease.
Z2 spin liquid in S=1/2 Heisenberg model on Kagome lattice: A projective symmetry group study of Schwinger-fermion mean-field states

description: With strong geometric frustration and quantum fluctuations, S=1/2 quantum Heisenberg antiferromagnets on the Kagome lattice has long been considered as an ideal platform to realize spin liquid (SL), a novel phase with no symmetry breaking and fractionalized excitations. A recent numerical study of Heisenberg S=1/2 Kagome lattice model (HKLM) show that in contrast to earlier studies, the ground state is a singlet-gapped SL with signatures of Z2 topological order. Motivated by this numerical discovery, we use projective symmetry group to classify all 20 possible Schwinger-fermion mean-field states of Z2 SLs on Kagome lattice. Among them we found only one gapped Z2 SL (which we call Z2[0,π]βstate) in the neighborhood of U(1)-Dirac SL state, whose energy is found to be the lowest among many other candidate SLs including the uniform resonating-valentce-bond states. We thus propose this Z2[0,π]βstate to be the numerically discovered SL ground state of HKLM.

Churches and public participation : the case of the Flint water crisis
Creators: name: Cicekci, Nazli
Publisher: name: University of British Columbia
Year: 2022

description: Scholars have examined how social and economic factors make local governments ineffective and contribute to environmental crises. In response to these crises, which vary from activism to advocacy, environmental non-governmental organizations (ENGOs) have strived for environmental and social justice. Consequently, research into ENGOs has received significant attention in current literature. However, the current literature has failed to consider the role of faith-based organizations (FBOs), particularly churches, in promoting community participation and activism. Hence, by diverting the main focus from NGOs to FBOs, this thesis aims to explore the roles of churches as a faith-based organizations in developing community participation in Flint, Michigan in response to the water crisis. Employing a qualitative approach, the thesis engages in thematic analysis to understand the emerging role of churches and their effectiveness in developing community-based participation and collective political mobilization in the Flint water crisis. The research finds that churches are involved in the process and outcomes of community-based participation in Flint to various degrees. The thesis explores the implications of church involvement in facilitating desired community participation and policy outcomes and concludes by recommending further work to develop a complete picture of the role of churches in community development in Flint.

description: We study the problem of Upward Point-Set Embeddability, that is the problem of deciding whether a given upward planar digraph $D$ has an upward planar embedding into a point set $S$. We show that any switch tree admits an upward planar straight-line embedding into any convex point set. For the class of $k$-switch trees, that is a generalization of switch trees (according to this definition a switch tree is a $1$-switch tree), we show that not every $k$-switch tree admits an upward planar straight-line embedding into any convex point set, for any $k \geq 2$. Finally we show that the problem of Upward Point-Set Embeddability is NP-complete.
