description: Quantum Key Distribution (QKD) is a technology that allows secure key exchange between two distant users. A widespread adoption of QKD requires the development of simple, low-cost, and stable systems. However, implementation of the current QKD requires a complex self-alignment process during the initial stage and an additional hardware to compensate the environmental disturbances. In this study, we have presented the implementation of a simple QKD with the help of a stable transmitter-receiver scheme, which simplifies the self-alignment and is robust enough to withstand environmental disturbances. In case of the stability test, the implementation system is able to remain stable for 48 hours and exhibits an average quantum bit error rate of less than 1\% without any feedback control. The scheme is also tested over a fiber spool, obtaining a stable and secure finite key rate of 7.32k bits per second over a fiber spool extending up to 75 km. The demonstrated long-term stability and obtained secure key rate prove that our method of implementation is a promising alternative for practical QKD systems, in particular, for Cubesat platform and satellite applications.

title: Reconstructing the 1980s on contemporary American television
Creators: name: Varadi, Anna Johanna
Publisher: name: University of Reading
Year: 2023

description: This thesis examines the reconstruction of the 1980s in nine American television programmes produced during the 2010s. It argues that recurring preoccupations with intimacy, identity politics, and performativity across vastly different programmes highlight continuities and tensions between past and present social issues in the USA. To do this, it asks how the formal and stylistic conventions of television contribute to contemporary depictions of the 1980s’ cultural heritage in America. By using an interdisciplinary approach, the thesis synthesises the close textual analysis of a wide range of recent programmes (The Americans, Red Oaks, Deutschland 83, The Carrie Diaries, Glow, Halt and Catch Fire, the Black Mirror episode ‘San Junipero’, The Goldbergs, and Stranger Things) with the analysis of 1980s and 2010s political contexts. The thesis begins by exploring the rising popularity of the 1980s in American television during the 2010s, highlighting key areas of comparison between the two decades, such as escalating racial and gender divides and similarities between Ronald Reagan and Donald Trump’s presidential campaigns. Chapter 1 situates the thesis within scholarship on media representations of the past, specifically regarding the parallels between the British heritage debate and scholarship on screening the American past. Chapter 2 analyses the performative construction of an American national community through shared historical myths pertaining to Reagan’s image, the English language, national symbols, and whiteness. Chapter 3 examines shifts and debates in feminist thought since the 1980s to explore why two programmes produced just five years apart use their 1980s setting in contrasting ways to explore white and black women’s experiences of privilege and prejudice, respectively. Chapter 4 reflects on historical developments in representations of sex and sexuality in American media to suggest that the 1980s becomes emotionally resonant for contemporary viewers through haptic images, immersive soundtracks, and references to the style of MTV. Lastly, Chapter 5 engages with Cold War-era anxiety about nuclear war in relation to television’s role in creating culturally significant images, the dissolution of the nuclear family, and a nostalgic return to 1980s childhood. The thesis concludes that the popularity of the 1980s in the 2010s is prompted by socio-political parallels that go beyond surface-level references to reveal the ways in which we negotiate social issues today. By using cultural and aesthetic codes of the 1980s, contemporary television engages with turbulent shifts in American society throughout the 2010s, making a case for reading the case studies as exponents of the lasting impact of the 1980s.

description: The nature of the low energy spectrum of frustrated quantum spin systems is investigated by means of a topological test introduced by Y. Hatsugai which enables to infer the possible existence or absence of a gap between the ground state and excited states of these systems. The test relies on the determination of an order parameter which is a Berry phase. The structure of the spectra of even and odd-legged systems in 2d and 3d is analyzed. Results are confronted with previous work.

description: Given a finite number of copies of an unknown qubit state that have already been measured optimally, can one still extract any information about the original unknown state? We give a positive answer to this question and quantify the information obtainable by a given observer as a function of the number of copies in the ensemble, and of the number of independent observers that, one after the other, have independently measured the same ensemble of qubits before him. The optimality of the protocol is proven and extensions to other states and encodings are also studied. According to the general lore, the state after a measurement has no information about the state before the measurement. Our results manifestly show that this statement has to be taken with a grain of salt, specially in situations where the quantum states encode confidential information.

Young child interview responses to anatomically detailed dolls : implications for practice and research in child sexual abuse
Creators: name: Goranson, Sandra Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: Assessments of allegations of sexual abuse of young children are being made based on investigative interviews with children using anatomically detailed dolls. These decisions are not based on a researched body of knowledge. This qualitative exploratory study involved interviewing fourteen, 3-5 year old children selected as likely to have a low risk of having been sexually abused using a model of the child sexual abuse investigative interview. It was found that the behaviours these children exhibited included those which are often of concern in regular assessments and may even be considered to be indicative of sexual abuse. The conceptual findings indicate that: 1) the anatomically detailed dolls appear to be a useful but not essential tool that should be used with considerable caution; 2) all such interviews should be video taped; 3) interviewers need to be knowledgable in the areas of child sexual abuse and child development. Further research is needed to establish the total range of investigative interview behaviours exhibited by nonabused children as well as to clarify what interview factors enhance and distort a child's presentation of a past history of child sexual abuse. Until this is accomplished the assumptions which are used to validate allegations of child sexual abuse will continue to fluctuate from interview to interview.

description: Recently, it has been shown that the radiation arising from quantum fields placed in a gravitational background (e.g. Hawking radiation) can be derived using a quasi-classical calculation. Here we show that this method has a previously overlooked temporal contribution to the quasi--classical amplitude. The source of this temporal contribution lies in different character of time in general relativity versus quantum mechanics. Only when one takes into account this temporal contribution does one obtain the canonical temperature for the radiation. Although in this letter the specific example of radiation in de Sitter space--time is used, the temporal contribution is a general contribution to the radiation given off by any gravitational background where the time coordinate changes its signature upon crossing a horizon. Thus, the quasi--classical method for gravitational backgrounds contains subtleties not found in the usual quantum mechanical tunneling problem.

description: Over the course of the last two decades, traditional models of planet formation have been repeatedly challenged by the emerging census of extrasolar planets. Key among them is the orbital architecture problem: while standard models of orbital migration predict resonant orbits for short-period objects, most planets do not appear to lie in orbital resonances. Here we show that the four-planet system Kepler-221, not previously recognized to have active orbital resonances, has a three-body commensurability relation unique within the Kepler sample. Using a suite of numerical experiments as well as a perturbative analysis, we demonstrate that this system likely began as a resonant chain and proceeded to undergo large-scale divergence away from resonance, under the action of tidal dissipation. Our results further indicate that obliquity tides, driven by a secular spin-orbit resonance and mutual inclination, are an excellent candidate for driving this orbital divergence, and that the high tidal luminosity may also explain the anomalous size of planet b, which lies within the Fulton radius gap.

Intervalley Tunneling and Crossover from the Positive to Negative Interlayer Magnetoresistance in Quasi-Two-Dimensional Dirac Fermion System with or without Mass Gap

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We theoretically investigate the interlayer magnetoresistance in quasi-two-dimensional Dirac fermion systems, where the Fermi energy is at the Dirac point. If there is an intermediate insulating layer that has an overlap with the wave functions in the Dirac fermion layers, there appears a positive magnetoresistance regime due to the intervalley tunneling. We show that the interlayer magnetoresistance can be used to find whether Dirac fermions are massive or not from the minimum in the interlayer magnetoresistance. As a specific system, we consider \alphaI under high pressure. We also discuss that one has to be careful in analyzing the crossover temperature from the positive to negative magnetoresistance. A simple picture is applied to the crossover in the zero temperature limit but it does not apply to the data at finite temperatures. We show that the ratio of the Fermi velocity to the scattering rate is evaluated from the zero temperature limit of the crossover temperature.

description: Il carcinoma epatico (HCC) rappresenta uno dei cancri più comuni nell’uomo rappresentando la 5a causa di tumore nel mondo. Il trattamento ottimale di questa neoplasia è rappresentato dalla chirurgia ma  purtroppo solo il 5-15% dei pazienti in cui viene messa in evidenza una lesione neoplastica del fegato può essere sottoposto a chirurgia resettiva potenzialmente curativa o a trapianto epatico. Negli ultimi anni si sono messe a punto metodiche alternative, cosidette non resettive o ablative, per il trattamento di lesioni non suscettibili di trattamento chirurgico. La tesi riporta l’esperienza nello sviluppo e sperimentazione in laboratorio e in test clinici preliminari di un innovativo sistema computerizzato di realtà virtuale che consente a partire da immagini TAC del paziente, di ricostruire in tre dimensioni organi ed eventuali lesioni tumorali del fegato. Queste immagini tridimensionali vengono quindi utilizzate per la pianificazione e la simulazione virtuale della procedura di inserimento dell’ago per radiofrequenza prima dell’intervento e nel corso della procedura per guidare realmente l’inserzione dell’ago senza bisogno di ulteriori sistemi di acquisizione di immagine tipo TAC.

description: The neutrino-nucleus reaction cross sections of 4He and 12C are evaluated using new shell model Hamiltonians. Branching ratios of various decay channels are calculated to evaluate the yields of Li, Be, and B produced through the nu-process in supernova explosions. The new cross sections enhance the yields of 7Li and 11B produced during the supernova explosion of a 16.2 M_odot star model compared to the case using the conventional cross sections by about 10%. On the other hand, the yield of 10B decreases by a factor of two. The yields of 6Li, 9Be, and the radioactive nucleus 10Be are found at a level of 10^{-11} M_odot. The temperature of nu_{mu,tau}- and bar{nu}_{mu,tau}-neutrinos inferred from the supernova contribution of 11B in Galactic chemical evolution models is constrained to the 4.3-6.5 MeV range. The increase in the 7Li and 11B yields due to neutrino oscillations is demonstrated with the new cross sections.

description: Learning from non-stationary data streams and overcoming catastrophic forgetting still poses a serious challenge for machine learning research. Rather than aiming to improve state-of-the-art, in this work we provide insight into the limits and merits of rehearsal, one of continual learning's most established methods. We hypothesize that models trained sequentially with rehearsal tend to stay in the same low-loss region after a task has finished, but are at risk of overfitting on its sample memory, hence harming generalization. We provide both conceptual and strong empirical evidence on three benchmarks for both behaviors, bringing novel insights into the dynamics of rehearsal and continual learning in general. Finally, we interpret important continual learning works in the light of our findings, allowing for a deeper understanding of their successes.

description: Explainable AI has emerged to be a key component for black-box machine learning approaches in domains with a high demand for reliability or transparency. Examples are medical assistant systems, and applications concerned with the General Data Protection Regulation of the European Union, which features transparency as a cornerstone. Such demands require the ability to audit the rationale behind a classifier's decision. While visualizations are the de facto standard of explanations, they come short in terms of expressiveness in many ways: They cannot distinguish between different attribute manifestations of visual features (e.g. eye open vs. closed), and they cannot accurately describe the influence of absence of, and relations between features. An alternative would be more expressive symbolic surrogate models. However, these require symbolic inputs, which are not readily available in most computer vision tasks. In this paper we investigate how to overcome this: We use inherent features learned by the network to build a global, expressive, verbal explanation of the rationale of a feed-forward convolutional deep neural network (DNN). The semantics of the features are mined by a concept analysis approach trained on a set of human understandable visual concepts. The explanation is found by an Inductive Logic Programming (ILP) method and presented as first-order rules. We show that our explanation is faithful to the original black-box model. The code for our experiments is available at https://github.com/mc-lovin-mlem/concept-embeddings-and-ilp/tree/ki2020.

We show an efficient way of generating cluster states directly using either the iSWAP gate for the XY model, or the $\sqrt{\rm SWAP}$ gate for the Heisenberg model. Our approach thus makes one-way quantum computing more feasible for solid-state devices.

description: Edible Cities Network (EdiCitNet) is a European demonstration program that recognizes the social importance of urban agriculture initiatives for the city. There are a multitude of initiatives of urban agriculture around the world, but EdiCitNet aims to empower local communities to overcome social problems by their inclusive and participatory dynamics and to create new green businesses
 and jobs, and thereby local economic growth and social cohesion. The overall objective of EdiCitNet is to launch and develop a sustainable and constantly growing network of cities, empowering their inhabitants by a common methodology: • to systematically explore the wealth and diversity of existing Edible City Solutions (ECS) and to build and share a common knowledge base,
 • to adapt, plan and implement successfully proven ECS in their specific urban
 context. The selection of the current EdiCitNet Living Labs (LL) (Andernach, Berlin, Oslo, Rotterdam and Havana) focuses on the most important societal challenges in European cities. In addition, the Living Lab Havana, as a pioneer of self-sustaining ECS, can reflect beneficial experiences and facilitate mutual support and interconnections beyond Europe. The EdiCitNet Living Labs represent not only different social, economic, and ecological requirements of a varied Europe, but already have a broad basis of Nature Based Solutions (NBS) experience. Every single living lab is convinced by ECS and has invested in its development and programmes for years. The different EdiCitNet living labs are to serve both as knowledge and application base for the following cities, as well as to raise ECS in the front runner cities to a new, solid level. The EdiCitNet Front-Runner Cities (FRC) do not necessarily follow the attempt of representing geopolitical large-scale zones via punctual case studies, but strictly highlight urgent urban problems like inclusiveness, social cohesion, wellbeing, mental and physical health, safety, and criminality. In their original Implementation Project Plans (IPPs, described in detail in the updated versions of D3.1) each city has formulated their own strategy to foster the urban agriculture initiatives in their cities. These strategies all include a co-creational framework in which all stakeholders concerned can partake in overcoming local challenges. The present document D3.2, contains a “Status report on the implementation of the living labs in the front-runner cities”. Apart from a detailed description of the implementations in the FRC since 2019 the document also provides insights on the unexpected impacts on the IPPs during the last years and gives an outlook on measures that will ensure the sustainability of the LLs.

description: The development of complex functional materials poses a multi-objective optimization problem in a large multidimensional parameter space. Solving it requires reproducible, user independent laboratory work and intelligent preselection of experiments. However, experimental materials science is a field where manual routines are still predominant, although other domains like pharmacy or chemistry have long used robotics and automation. As the number of publications on Materials Acceleration Platforms (MAPs) increases steadily, we review selected systems and fit them into the stages of a general material development process to examine the evolution of MAPs. Subsequently we present our approach to laboratory automation in materials science. We introduce AMANDA (Autonomous Materials and Device Application Platform), a generic platform for distributed materials research comprising a self-developed software backbone and several MAPs. One of them, LineOne (L1), is specifically designed to produce and characterize solution processed thin-film devices like organic solar cells (OSC). It is designed to perform precise closed-loop screenings of up to 272 device variations per day yet allows further upscaling. Each individual solar cell is fully characterized and all process steps are comprehensively documented. We want to demonstrate the capabilities of AMANDA L1 with OSCs based on PM6:Y6 with 13.7% efficiency when processed in air. Further we discuss challenges and opportunities of highly automated research platforms and elaborate on the future integration of additional techniques, methods and algorithms in order to advance to fully autonomous self-optimizing systems - a paradigm shift in functional materials development leading to the laboratory of the future.

description: Poly(benzimidazole) (PBI) has received considerable attention as an effective high-temperature polymer electrolyte membrane for fuel cells. In this work, the Grotthuss mechanism for bifunctional proton transfer in PBI membranes was studied using density functional theory and transition state theory. This study focused on the reaction paths and kinetics for bifunctional proton transfer scenarios in neutral ([PBI]2), single (H+[PBI]2) and double-protonated (H2+[PBI]2) dimers. The theoretical results showed that the energy barriers and strength for H-bonds are sensitive to the local dielectric environment. For [PBI]2 with ε = 1, the uphill potential energy curve is attributed to extraordinarily strong ion-pair H-bonds in the transition structure, regarded as a ‘dipolar energy trap’. For ε = 23, the ion-pair charges are partially neutralized, leading to a reduction in the electrostatic attraction in the transition structure. The dipolar energy trap appears to prohibit interconversion between the precursor, transition and proton transferred structures, which rules out the possibility for [PBI]2 to be involved in the Grotthuss mechanism. For H+[PBI]2 and H2+[PBI]2 with ε = 1, the interconversion involves a low energy barrier, and the increase in the energy barrier for ε = 23 can be attributed to an increase in the strength of the protonated H-bonds in the transition structure: the local dielectric environment enhances the donor–acceptor interaction of the protonated H-bonds. Analysis of the rate constants confirmed that the quantum effect is not negligible for the N–H+ … N H-bond especially at low temperatures. Agreement between the theoretical and experimental data leads to the conclusion that the concerted bifunctional proton transfer in H2+[PBI]2 in a high local dielectric environment is ‘the rate-determining scenario’. Therefore, a low local dielectric environment can be one of the required conditions for effective proton conduction in acid-doped PBI membranes. These theoretical results provide insights into the Grotthuss mechanism, which can be used as guidelines for understanding the fundamentals of proton transfers in other bifunctional H-bond systems.

description: This file is a supplementary document for the paper "A Fast Quantum Algorithm for Searching the Quasi-optimal Solutions of Unit Commitment". Four sections are included. Section 1 introduces some basic quantum gates. Section 2 is the proof of Theorem 1 of the paper. In Section 3, an 11-qubit quantum circuit that performs Grover's search is described in detail, which consists of an oracle built with a physics-informed circuit and a variational quantum circuit. In Section 4, it is elaborated how a nonlinear support vector machine (SVM) can be trained to separate from the infeasible and non-suboptimal ones the union of ϵ-suboptimal solutions of a bundle of UC problem instances.
University student records : privacy and research access
Creators: name: Isaac, Glen E.
Publisher: name: University of British Columbia

description: This thesis examines the legal, ethical, and procedural issues faced by Canadian university archivists who seek to develop sound policies for research access to student records. The study begins by reviewing the basic types of student records created by university administrative offices--including academic, personnel, financial, medical, and counselling files—as well as some of the current and potential uses of the records by researchers. The thesis then turns to a study of the "right to privacy" itself, and explores how the privacy concerns of the subjects of personal records have been been addressed in government studies and in Canadian law. The existing records policies of Canadian universities and various ethical statements of both university administrators and researchers are also examined. In this manner, the complex problem of balancing privacy rights with research needs is viewed from the perspective of the subjects, creators, and users of student records. The study concludes by reviewing the choices open to archivists with regards to the formulation of access policies. Several opposing views of privacy are evaluated in order to identify those views which can be supported by archivists and those which cannot. The argument is made that archivists need to construct a solid theoretical framework for their access policies by analyzing carefully such factors as the ends to be served by the protection of privacy, the types of research access to be provided to student files, and the nature of the university administrative environment. It is contended that such an analysis indicates a need for policies consisting of graduated sets of access restrictions--policies which are sufficiently flexible and sensitive to guard against unwarranted invasions of student privacy while still permitting a broad range of research studies to be conducted.

description: We propose a scheme which implements a controllable change of the state of the target spin qubit in such a way that both the control and the target spin qubits remain in their ground states. The interaction between the two spins is mediated by an auxiliary spin, which can transfer to its excited state. Our scheme suggests a possible relationship between the gate and adiabatic quantum computation.

description: The unexpected Ebola virus outbreak in West Africa in 2014 involving the Zaire ebolavirus made clear that other regions outside Central Africa, its previously documented niche, were at risk of future epidemics. The complex transmission cycle and a lack of epidemiological data make mapping areas at risk of the disease challenging. We used a Geographic Information System-based multicriteria evaluation (GIS-MCE), a knowledge-based approach, to identify areas suitable for Ebola virus spillover to humans in regions of Guinea, Congo and Gabon where Ebola viruses already emerged. We identified environmental, climatic and anthropogenic risk factors and potential hosts from a literature review. Geographical data layers, representing risk factors, were combined to produce suitability maps of Ebola virus spillover at the landscape scale. Our maps show high spatial and temporal variability in the suitability for Ebola virus spillover at a fine regional scale. Reported spillover events fell in areas of intermediate to high suitability in our maps, and a sensitivity analysis showed that the maps produced were robust. There are still important gaps in our knowledge about what factors are associated with the risk of Ebola virus spillover. As more information becomes available, maps produced using the GIS-MCE approach can be easily updated to improve surveillance and the prevention of future outbreaks.

description: We develop a novel method in classifying the multipartite entanglement state of $2\times N\times N$ under stochastic local operation and classical communication. In this method, all inequivalent classes of true entangled state can be assorted directly without knowing the classification information of lower dimension ones for any given dimension $N$. It also gives a nature explanation for the non-local parameters remaining in the entanglement classes while $N\geq 4$ .

description: We study the behavior of black hole singularities across the Hawking-Page phase transitions, uncovering possible connections between the physics inside and outside the horizon. We focus on the case of spacelike singularities in Einstein-scalar theory which are of the Kasner form. We find that the Kasner exponents are continuous and non-differentiable during the second order phase transitions, while discontinuous in the first order phase transitions. We give some arguments on the universality of this behavior. We also discuss possible observables in the dual field theory which encode the Kasner exponents.

description: We address quantum critical systems as a resource in quantum estimation and derive the ultimate quantum limits to the precision of any estimator of the coupling parameters. In particular, if L denotes the size of a system and λis the relevant coupling parameters driving a quantum phase transition, we show that a precision improvement of order 1/L may be achieved in the estimation of λat the critical point compared to the non-critical case. We show that analogue results hold for temperature estimation in classical phase transitions. Results are illustrated by means of a specific example involving a fermion tight-binding model with pair creation (BCS model).

description: The growth of methane concentration in the atmosphere affects climate change (United States Environmental Protection Agency (EPA), 2021). Methane has a global warming potential over100 years that is 25 times higher than Carbon dioxide (CO2) per ton gas released (Forster & Ramaswamy, 2007). About 60% of global methane emissions are coming from human activities, including oil and gas, which contributes 33% (United Nations Economic Commission for Europe (UNECE), 2021). Methane emissions are possible across the whole supply chain of the oil and gas industry, from oil exploration to the end-user. This study focuses on the emission group in the oil upstream segment, associated with the well's failed sealingsystem. The first objective of this report is to assess the possible reduction of methaneemissions associated with failures of the well's sealing system in those cases where repair is technically feasible. The second objective is to evaluate the required costs for implementing such measures in the context of additional expenses for each produced ton of oil.Several chapters of the study introduce the reader to the term well integrity, explaining the basic principles of the well construction process and the possible causes of integrity failures.Emissions reduction estimation requires several parameters, and some are not available (e.g.,not measured), such as the share of the oil wells in Russia with integrity issues. Therefore,experts with vast experience in Russia's oil and gas industry were surveyed to fill the informational gaps and determine the required parameters.The study discovers that it is possible to reduce methane emissions associated with the well'sintegrity issues by 78 kt CH4 a year, representing 17% of the category "Oil and venting" from the oil upstream segment in Russia (462 kt CH4 per year as of 2017). Additional costs would be required to restore the integrity of wells in Russia to mitigate methane emissions estimates as 3 US$ per ton of oil produced. Well integrity restoration has a double positive implication.The positive effect on climate change by methane emissions reduction. Additionally, the oilproducers would also benefit from the integrity restoration due to the extended life of the well,and increased of oil production. Therefore, targeting oil wells' integrity to reduce methaneemissions could be quick to implement and relatively low-cost solution for methane emissionsreduction in the oil upstream segment.

description: Digital transformation is reshaping African economies, yet a noticeable divide exists between Anglophone and Francophone countries regarding cybersecurity and digital maturity. This paper examines how cultural, legal, and historical legacies influence these differing trajectories. Drawing on theories of colonial legacy, cultural capital, and innovation systems, a mixed-methods approach—including qualitative case studies and quantitative comparisons—highlights differences in regulatory frameworks, private sector engagement, and educational infrastructures. The findings suggest that anglophone countries’ adaptable legal systems, robust international partnerships, and access to English-dominant digital resources offer distinct advantages over their francophone counterparts. Implications for policy reform and harmonizing digital strategies across the continent are discussed.
