description: The electrical characteristics of composites based on polyimide and graphene were studied. The films of PI R-ODFO, in which the solvents N-MP and DMAA were used, were studied. The solvent content varied from 14% to 22%. It was found that the nature of the solvent, as well as its percentage (14% â 22%) do not affect the electrical properties of the composite material. The influence of the filler concentration on the conductivity of the composite has been studied. It was found that with a filler content of 0.5%, a percolation threshold is observed, while the conductivity increases by 7 orders of magnitude.

description: We have experimentally studied few-body impurity systems consisting of a single fermionic atom and a small bosonic field on the sites of an optical lattice. Quantum phase revival spectroscopy has allowed us to accurately measure the absolute strength of Bose-Fermi interactions as a function of the interspecies scattering length. Furthermore, we observe the modification of Bose-Bose interactions that is induced by the interacting fermion. Because of an interference between Bose-Bose and Bose-Fermi phase dynamics, we can infer the mean fermionic filling of the mixture and quantify its increase (decrease) when the lattice is loaded with attractive (repulsive) interspecies interactions.

description: Con questa breve ricerca quantitativa, a cui hanno partecipato alcuni docenti di scuola media del Cantone Ticino, si è cercato di esplorare qual è la loro opinione in merito alle persone omosessuali e quali sono i fattori che la influenzano. Agli insegnanti è stato chiesto di compilare un questionario inserendo dapprima degli indicatori sociodemografici, per poi rispondere a delle domande. Successivamente hanno dovuto esprimere il loro accordo o disaccordo rispetto a delle opinioni concernenti le persone omosessuali. I principali risultati dello studio sono: a) la maggior parte dei docenti reputa che l’istituto scolastico in cui insegna sia sicuro per le persone omosessuali; b) la maggior parte degli insegnanti non ha pregiudizi nei confronti delle persone omosessuali; c) il sesso, l’età, l’orientamento religioso, il titolo di studio e l’orientamento politico non influenzano le opinioni dei docenti. I dati raccolti ci permettono di avere uno sguardo sulla percezione dell’omosessualità di alcuni insegnanti che lavorano all’interno della scuola media ticinese, così da poter riflettere sulle ricadute educative e didattiche delle tematiche LGBTIQ+, poiché la visione del docente è l’anticamera del suo agire educativo.

description: Phenotypes are partly shaped by the environment, which can impact both short-term adaptation and long-term evolution. In dioecious species, the two sexes may exhibit different degrees of phenotypic plasticity and theoretical models indicate that such differences may confer an adaptive advantage when the population is subject to directional selection, either because of a systematically varying environment or of a load of deleterious mutations. The effect stems from the fundamental asymmetry between the two sexes: female fertility is more limited than male fertility. Whether this asymmetry is sufficient for sexual dimorphism in phenotypic plasticity to evolve is, however, not obvious. Here, we show that even in conditions where it provides an adaptive advantage, dimorphic phenotypic plasticity may be evolutionarily unstable due to sexual selection. This is the case, in particular, for panmictic populations where mating partners are formed at random. However, we show that the effects of sexual selection can be counteracted when mating occurs within groups of related individuals. Under this condition, sexual dimorphism in phenotypic plasticity cannot only evolve but offset the twofold cost of males. We demonstrate these points with a simple mathematical model through a combination of analytical and numerical results.

description: The number of BPS bound states of D-branes on a Calabi-Yau manifold depends on two sets of data, the BPS charges and the stability conditions. For D0 and D2-branes bound to a single D6-brane wrapping a Calabi-Yau 3-fold X, both are naturally related to the Kahler moduli space M(X). We construct unitary one-matrix models which count such BPS states for a class of toric Calabi-Yau manifolds at infinite 't Hooft coupling. The matrix model for the BPS counting on X turns out to give the topological string partition function for another Calabi-Yau manifold Y, whose Kahler moduli space M(Y) contains two copies of M(X), one related to the BPS charges and another to the stability conditions. The two sets of data are unified in M(Y). The matrix models have a number of other interesting features. They compute spectral curves and mirror maps relevant to the remodeling conjecture. For finite 't Hooft coupling they give rise to yet more general geometry \widetilde{Y} containing Y.

description: We study in this paper the sine-Gordon model using functional Renormalization Group (fRG) at Local Potential Approximation (LPA) using different RG schemes. In $d=2$, using Wegner-Houghton RG we demonstrate that the location of the phase boundary is entirely driven by the relative position to the Coleman fixed point even for strongly coupled bare theories. We show the existence of a set of IR fixed points in the broken phase that are reached independently of the bare coupling. The bad convergence of the Fourier series in the broken phase is discussed and we demonstrate that these fixed-points can be found only using a global resolution of the effective potential. We then introduce the methodology for the use of Average action method where the regulator breaks periodicity and show that it provides the same conclusions for various regulators. The behavior of the model is then discussed in $d\ne 2$ and the absence of the previous fixed points is interpreted.

description: We use large-scale molecular dynamics simulations to study the kinetics of the liquid-gas phase separation if the temperature is lowered across the glass transition of the dense phase. We observe a gradual change from phase separated systems at high temperatures to nonequilibrium, gel-like structures that evolve very slowly at low temperatures. The microscopic mechanisms responsible for the coarsening strongly depend on temperature, and change from diffusive motion at high temperature to a strongly intermittent, heterogeneous and thermally activated dynamics at low temperature, leading to logarithmically slow growth of the typical domain size.

description: Management of data is an important element of large scale multi-disciplinary projects. As such, MARBEL will be collecting, using and generating a heterogeneous set of data throughout its lifecycle. This deliverable is the initial version of the project’s Data Management Plan and explains the proposed actions for the overall control of MARBEL’s data and publications. More specifically the following points are addressed:

The guiding principles for data management in the project

Data Summary, including an overview of what data will be gathered and processed in the project

Provisions and principles for finable, accessible, interoperable, and reusable (FAIR) Data Management

Allocation of resources and the costs for data management in this project

Provisions for data security as well as the adherence to the General Data Protection Directive (GDPR)

Ethical aspects, the MARBEL privacy strategy as well as IPR issues.

The DMP provides a framework for good data handling by identifying the research data that the project expects to generate and describing which parts of the data can be shared with the public. Furthermore, it provides guidelines on naming conventions and metadata, storage of research data and steps to make them public available.MARBEL will make use or open research data repositories such as Zenodo to comply with the Horizon 2020 Open Access policy. Public deliverables, publications and anonymized datasets will be made available with open access. Datasets generated by MARBEL will be given a persistent identifier (Digital Object Identifier, DOI), supplied with relevant metadata referencing the project name and grant agreement number. Ethical aspects related to data collection, generation and sharing will be considered for data collection, use and sharing. The DMP is a living document and will be periodically updated, as part of the project’s periodic reports in order to reflect the actual research data generated during the project and include updated instructions on accessing open data.

The Large-Scale Mining (LSM) - informal Artisanal-Scale Mining (ASM) interface in Peru : exploring a key policy "bottleneck" through Qualitative Comparative Analysis (QCA)
Creators: name: Cano Roncagliolo, Alvaro
Publisher: name: University of British Columbia
Year: 2020

description: Approximately 20% of the world's gold is produced by the Artisanal and Small-Scale Mining (ASSM) sector and over 150 million people depend on the activity to sustain their livelihoods. Between 2002 and 2012, the price of gold in the international metal market caused an explosion of informal ASM activities in Peru, modifying, in key “mining corridors”, the relationships between formal mining (mostly Large-Scale Mining or LSM and Medium-Scale Mining (MSM) and informal mining (mostly Artisanal-Scale Mining or ASM). It is estimated that there are between 300,000 and 500,000 artisanal miners in Peru and further 1 million people linked to the activity, which produces 20% of Peruvian gold. Only 60,000 are registered in the State’s formalization process but to complete the formalization process, at least 64% of these cases require an “Exploitation Contract (EC)”, granted by the formal concession holder. This instrument has been the main “bottleneck” in the Peruvian formalization process and at the interface between these types of mining since 2012. This study applies a Qualitative Comparative Analysis (QCA) methodology to explore the influence that 5 theorized conditions may have played in bringing about an Exploitation Contract between formal-LSM and informal-ASM scales. The absence or presence of these 5 conditions are arranged in a binary “Truth Table” for an intermediate “N” of 20 cases of the interface, representing diversity in terms of positive and negative outcomes. The results indicate that arriving at an EC in Peru, due to the lack of state presence in mining regions, is an issue to be solved mainly among private parties. Accordingly, the QCA application indicates that there are two necessary conditions to arrive at an EC: (1) a strong willingness to formalize a mining business on behalf of ASSM producers and, (2) a strong corporate incentive or “business case” for LSM companies to support ASM formalization within their concessions. In addition, the participation of a third actor or State’s active role, and a corporate culture appropriate to engage ASM producers, while not necessary conditions to bring about the EC, are consistently present in the “pathways” or “solution formulas” that arrive at an EC.

description: It is demonstrated that upon pulsed microwave excitation, the temporal behavior of a spin-wave induced inverse spin Hall voltage in a magnetic insulator-nonmagnetic metal structure is distinctly different from the temporal evolution of the directly excited spin-wave mode from which it originates. The difference in temporal behavior is attributed to the excitation of long-lived secondary spin-wave modes localized at the insulator-metal interface.
Influence of Quantum Critical Point of First Order Valence Transition on Ce- and Yb-Based Heavy Fermions

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

description: Influence of quantum critical point (QCP) of first-order valence transition (FOVT) on Ce- and Yb-based heavy fermions is discussed as a key origin of anomalies such as non-Fermi liquid, metamagnetism, and unconventional superconductivity. Even in intermediate-valence materials, the QCP of the FOVT is shown to be induced by applying a magnetic field, which creates a new characteristic energy distinct from the Kondo temperature. It is stressed that the key concept is closeness to the QCP of the FOVT by pointing out that the proximity of the QCP explains sharp contrast between X=Ag and X=Cd in YbXCu4, field-induced valence crossover in X=Au, and field-induced first order transition as well as non-Fermi-liquid critical behaviours in CeIrIn5. The valence fluctuations can be a key origin of unresolved phenomena in this family of materials.

description: The danger posed by falsified media, commonly referred to as deepfakes, has been well researched and documented. The software Faceswap to was used to swap the faces of two politician (Joe Biden and Donald Trump). The testing was performed using an affordable consumer GPU (an AMD Radeon RX 570) over 100,000 iterations. The process and results for the two attempts with the best results (and largest differences) were recorded. The result was ultimately unconvincing, while the software was able to recreate the facial structure the lighting and skin tone did not blend at all.
Factorization and infrared properties of non-perturbative contributions to DIS structure functions

description: In this paper we present a new derivation of the QCD factorization. We deduce the k_T- and collinear factorizations for the DIS structure functions by consecutive reductions of a more general theoretical construction. We begin by studying the amplitude of the forward Compton scattering off a hadron target, representing this amplitude as a set of convolutions of two blobs connected by the simplest, two-parton intermediate states. Each blob in the convolutions can contain both the perturbative and non-perturbative contributions. We formulate conditions for separating the perturbative and non-perturbative contributions and attributing them to the different blobs. After that the convolutions correspond to the QCD factorization. Then we reduce this totally unintegrated (basic) factorization first to the k_T- factorization and finally to the collinear factorization. In order to yield a finite expression for the Compton amplitude, the integration over the loop momentum in the basic factorization must be free of both ultraviolet and infrared singularities. This obvious mathematical requirement leads to theoretical restrictions on the non-perturbative contributions (parton distributions) to the Compton amplitude and the DIS structure functions related to the Compton amplitude through the Optical theorem. In particular, our analysis excludes the use of the singular factors x^{-a} (with a > 0) in the fits for the quark and gluon distributions because such factors contradict to the integrability of the basic convolutions for the Compton amplitude. This restriction is valid for all DIS structure functions in the framework of both the k_T- factorization and the collinear factorization if we attribute the perturbative contributions only to the upper blob.

description: Core-collapse supernova neutrinos undergo a variety of phenomena when they travel from the high neutrino density region and large matter densities to the Earth. We perform analytical calculations of the supernova neutrino fluxes including collective effects due to the neutrino-neutrino interactions, the Mikheev-Smirnov-Wolfenstein (MSW) effect due to the neutrino interactions with the background matter and decoherence of the wave packets as they propagate in space. We predict the numbers of one- and two-neutron charged and neutral-current electron-neutrino scattering on lead events. We show that, due to the energy thresholds, the ratios of one- to two-neutron events are sensitive to the pinching parameters of neutrino fluxes at the neutrinosphere, almost independently of the presently unknown neutrino properties. Besides, such events have an interesting sensitivity to the spectral split features that depend upon the presence/absence of energy equipartition among neutrino flavors. Our calculations show that a lead-based observatory like the Helium And Lead Observatory (HALO) has the potential to pin down important characteristics of the neutrino fluxes at the neutrinosphere, and provide us with information on the neutrino transport in the supernova core.

description: Recent claims that the strength B_IGMF of the intergalactic magnetic field (IGMF) is >~ 1e-15 G are based on upper limits to the expected cascade flux in the GeV band produced by blazar TeV photons absorbed by the extragalactic background light. This limit depends on an assumption that the mean blazar TeV flux remains constant on timescales >~2 (B_ IGMF/1e-18 G)^2 / (E/{10 GeV})^2 yr for an IGMF coherence length ~ 1 Mpc, where E is the measured photon energy. Restricting TeV activity of 1ES 0229+200 to ~3 -- 4 years during which the source has been observed leads to a more robust lower limit of B_IGMF >~ 1e-18 G, which can be larger by an order of magnitude if the intrinsic source flux above ~5 -- 10 TeV from 1ES 0229+200 is strong.

description: Even though American women had higher rates of involvement in the Vietnam War than any previous war, poems about their experiences were extremely scarce until over a decade after American troops withdrew. A major contributor to the lack of literary representation is the critical dismissal of women’s war poetry as being unable to teach readers meaningful “truths” about war. This thesis examines two collections of female-authored poems, Visions of War, Dreams of Peace and Shallow Graves, which were published in 1991 and 1986 respectively. The former contains poems from 40 women, most of whom served as army nurses; the latter combines the experiences of Wendy Wilder Larsen, an American woman who lived in Vietnam for two years, and Tran Thi Nga, a Vietnamese woman who immigrated to America. The collections reveal that most American women responded to critical expectations either through self-erasure or active rebellion. In contrast to the American women, Nga is granted authority by critics because her Vietnamese perspective is unique in English literature, but her authorship is instead challenged during the process of adapting her story for an American audience.

description: Quantum simulators are controllable quantum systems that can reproduce the dynamics of the system of interest, which are unfeasible for classical computers. Recent developments in quantum technology enable the precise control of individual quantum particles as required for studying complex quantum systems. Particularly, quantum simulators capable of simulating frustrated Heisenberg spin systems provide platforms for understanding exotic matter such as high-temperature superconductors. Here we report the analog quantum simulation of the ground-state wavefunction to probe arbitrary Heisenberg-type interactions among four spin-1/2 particles . Depending on the interaction strength, frustration within the system emerges such that the ground state evolves from a localized to a resonating valence-bond state. This spin-1/2 tetramer is created using the polarization states of four photons. The single-particle addressability and tunable measurement-induced interactions provide us insights into entanglement dynamics among individual particles. We directly extract ground-state energies and pair-wise quantum correlations to observe the monogamy of entanglement.
Virginity as metaphor : reconciling tradition and imperium in Achilles Tatius
Creators: name: Gao, Dora Yuanxing
Publisher: name: University of British Columbia
Year: 2020

description: This thesis investigates Achilles Tatius’s treatment of virginity as a metaphor for Greek tradition in his Leucippe and Clitophon. As one of the five surviving Greek novels from the Second Sophistic period, the text follows the adventures of two lovers who are separated and must weather various hardships across Egypt and Anatolia in order finally to reunite and marry. While previous scholarship on the novel has focused on genre, prose, and narrative elements, the present work approaches the text by centering its analysis on vulnerable populations associated with Artemis and her cult at Ephesus. Such a reading pushes our understanding of the Second Sophistic past usual studies of the philological responses of elite, educated men to upheaval. It instead focuses our attention on marginalized groups who have traditionally been excluded from the historical record and frames processes of cultural interaction and change as a negotiation of agency. In order to do so, this study first explores Achilles Tatius’s construction of Artemis as a goddess defined primarily by her connection to and protection of virgins, as traditionally depicted throughout Greek mythology. By also portraying the goddess in the context of her worship at Ephesus, he simultaneously constructs her as a Panhellenic goddess and the deity of a large and influential cult within the Roman Empire. The next chapter then analyzes Achilles Tatius’s treatment of virginity as a peculiarly feminine concern which both problematizes the institution of marriage and invites readers to consider alternate interpretations of the novel’s ending. Finally, this thesis discusses the Greek practice of asylum, specifically in the context of refuge at the Ephesian Artemisium, and the ways in which the author’s emphasis on virgin asylum seekers both responds to Roman anxieties and depicts the custom in a positive light. Taken together, these three chapters demonstrate how Achilles Tatius’s use of virginity as a metaphor for Greek heritage allows him to frame the reconciliation of Greek tradition with Roman imperium as a negotiation of agency between marginalized groups and power.

description: We calculate the drag and diffusion coefficients in low temperature QED plasma and go beyond the leading order approximation. The non-Fermi-liquid behavior of these coefficients are clearly revealed. We observe that the subleading contributions due to the exchange of soft transverse photon in both cases are larger than the leading order terms coming from the longitudinal sector. The results are presented in closed form at zero and low temperature.

title: Human Behavior Is a Significant Flaw in Maintaining Cyber Security
Creators: name: Jackson, Elizabeth
Publisher: name: Old Dominion University Libraries

description: Human behavior and data security utilization must be intertwined; in order to mitigate the negative effects of cyber attacks. No consumer wants their data hacked, breached, stolen, shared or wiped out. It is imperative to survey the type of education is needed to keep users safe and interested in securing their data. This can be done by simply seeking out the consumer's view of data security. The information obtained would allow the cybersecurity community to offer a simple way for consumers to protect their mobile data. There is a constant interaction between human behavior and the need for increased data encryption. Because technology increases convenience to the human experience; there will always be a point where the fine line between the two poses a significant risk to providing adequate cybersecurity.

Humanity's emotional involvement in this complex process leads to outcomes that do not reflect the need for optimized data encryption. Thus there is an inherent need to practice logic and pragmatism in decision making regarding when to protect it and ultimately how to protect one's data. Having total protection along with overall security is deemed impractical due. The dilemma is always how much security is too much and how much opened data is too much. This is an individual question that most of us struggle with in today's environment. The most secure storage device is a rock, but it does not share data very efficiently.

That does not mean that optimal data protection (freedom of use and encrypted use) cannot be achieved; without regard to emotive decision making. The objective of this paper is to identify how human behavior is one of the greatest contributing factors is human behavior contributing to the lack of security. My focus will be narrowed down to weaknesses that occur due to inadequate cell phone data encryption methods being used. The lapse in data security lends the wireless community vulnerable to critical data breaches. These breaches permit threats that affect corporations, communities, and end users on a global scale. Where there is a lapse in data encryption there is also an exploitable loophole for malware and hackers.

description: Spontaneous CP violation motivates the introduction of two Higgs doublets in the electroweak theory. Such a simple extension of the standard model has three neutral Higgs bosons and a pair charged Higgs, especially it leads to rich CP-violating sources including the induced Kobayashi-Maskawa CP-violating phase, the mixing of the neutral Higgs bosons due to the CP-odd Higgs and the effective complex Yukawa couplings of the charged and neutral Higgs bosons. Within this model, we present the production of a charged Higgs boson in association with a W boson at the LHC, and calculate in detail the cross section and the transverse momentum distribution of the associated W boson.

description: A recent paper of Arnold, Falk, and Winther [Bull AMS, 47 (2010)] showed that a large class of mixed finite element methods can be formulated naturally on Hilbert complexes, where using a Galerkin-like approach, one solves a variational problem on a finite-dimensional subcomplex. In a seemingly unrelated research direction, Dziuk [Lect Notes in Math, vol 1357 (1988)] analyzed a class of nodal finite elements for the Laplace-Beltrami equation on smooth 2-surfaces approximated by a piecewise-linear triangulation; Demlow later extended this analysis [SIAM J Numer Anal, 47 (2009)] to 3-surfaces, as well as to higher-order surface approximation. In this article, we bring these lines of research together, first developing a framework for the analysis of variational crimes in abstract Hilbert complexes, and then applying this abstract framework to the setting of finite element exterior calculus on hypersurfaces. Our framework extends the work of Arnold, Falk, and Winther to problems that violate their subcomplex assumption, allowing for the extension of finite element exterior calculus to approximate domains, most notably the Hodge-de Rham complex on approximate manifolds. As an application of the latter, we recover Dziuk's and Demlow's a priori estimates for 2- and 3-surfaces, demonstrating that surface finite element methods can be analyzed completely within this abstract framework. Moreover, our results generalize these earlier estimates dramatically, extending them from nodal finite elements for Laplace-Beltrami to mixed finite elements for the Hodge Laplacian, and from 2- and 3-dimensional hypersurfaces to those of arbitrary dimension. By developing this analytical framework using a combination of general tools from differential geometry and functional analysis, we are led to a more geometric analysis of surface finite element methods, whereby the main results become more transparent.

An evaluation of mining camp food waste management practices in Canada : an overview
Creators: name: Sayannyambuu, Mandakh-Erdene
Publisher: name: University of British Columbia
Year: 2020

description: The mining industry is facing increasing scrutiny to demonstrate that sustainability considerations are taken into account in their operations. This research approaches food waste as an overlooked, yet important issue that can advance not only environmental responsibility but also social and economic concerns within the mining industry. The implications of food waste generation on greenhouse gases, use of energy, groundwater contamination, and landfill space required are also critical concerns for the mining industry in the context of sustainability. This study evaluates the efforts that food service supply companies in mining camps are implementing to limit their food waste and assesses whether the prevention of food waste is a priority for these companies. This study used an online survey as the primary methodology for data collection. The survey resulted in a sample of eight respondents. Survey responses were structured based on the type of food waste, quantity, and causes of the waste. These were then mapped into pre- and post-consumer phases of the food services. Results indicated that proactive action to prevent food waste was not a priority for the respondents. The findings showed that the "vegetable" category had the highest amount of food waste throughout the different phases. Six out of eight companies did not measure the quantity of wasted food. During pre-consumer phase, difficulty in assessing demand, and confusion over dates were the most frequently cited causes for wastage. At the same time, overproduction was the leading cause of wastage in the post-consumer phase. Further complimenting the survey findings, the potential for the re-utilization of food waste through the creation of compost and alternative energy sources, was evaluated. The improvements identified with regard to food handling practices and potential re-utilization, are significant. Suggestions regarding the prevention of food waste highlighted many ways in which foodservice supply companies, as well as the mining industry, could benefit. Within these benefits, there exist great opportunities to contribute to Sustainable Development Goals, especially SDG12.3. Increased efficiencies with respect to food waste would reduce the environmental footprint, lead to potential re-utilization of food waste for electricity and gas generation, and increase profitability.
