description: L’introduzione al volume, oltre ad illustrare l’articolazione dello stesso nelle sue sottosezioni e il contenuto dei singoli saggi, propone anche una mappatura dei diversi momenti in cui la riflessione sul cinema si è incontrata in modo significativo con la questione del mito. Tale mappatura rende conto dell’influenza intermittente, eppure sostanziale, che le categorie mitiche hanno esercitato sui film studies, individuando quattro assi portanti del discorso. Il primo riguarda il rapporto tra dispositivo cinematografico e pensiero magico, ovvero l’idea del cinema come modalità di sopravvivenza del primitivo nel moderno (Morin). Il secondo ambito concerne invece gli studi sul divismo come forma di mitopoiesi (Barthes e anche qui Morin). La terza linea consiste nella riflessione condotta dalla Feminist Film Theory sull’immagine femminile, che la società patriarcale tende ad associare al mito come modalità di negazione di una soggettività pienamente storica dotata di agency. Quarto ed ultimo momento di intreccio tra cinema e mito è lo studio dei generi, che esso parta da prospettive strutturaliste, dalla psicoanalisi junghiana o da un impianto cognitivista.

Investigating gel properties of amino acid-based multicomponent low molecular weight gelators
Creators: name: Loos, Jeanette Nicole
Publisher: name: University of British Columbia
Year: 2024

description: Supramolecular gels were prepared from low molecular weight gelators and explored for their various properties. Amino acids were used for synthesizing the gelators, because of their biocompatibility and availability, creating a series of compounds to investigate for gel behavior. First, the properties of gels prepared from individual amino acid-based gelators were evaluated and compared with gels prepared from combinations of two gelators. Through the addition of a second gelator, it was found that the optical properties of the gel could be tuned between transparent and opaque by changing the component ratio in the gel. The properties were investigated using UV-Vis spectrophotometry, rheology, differential scanning calorimetry and small angle X-ray scattering. This work highlights the advantage of multicomponent gels to modify the gel’s behavior, allowing new soft materials to be developed. Second, a series of amino acid-based gelators was synthesized to understand the link between molecular design and gelation behavior. The self-assembly, minimum gelation concentration and structural design were compared by collecting data using differential scanning calorimetry and small angle X-ray scattering. The collected data were analyzed using statistical analysis where correlations were found between self-assembly/gelation concentration and gelator design. This allows for a design handbook to be created for researchers to design a gelator with known properties prior to testing, which currently is challenging to predict. Lastly, five multicomponent gelators were studied for their ability to form stable free-standing gels. Rheology experiments showed that the gels have excellent mechanical stability, so gels were cast in molds and retained their shape. Experiments were conducted to evaluate the diffusion of a guest in the gel, which showed the dynamic nature of the gel, with guest diffusion depending on solvent compatibility. These gels showed the dynamic nature of the supramolecular gel, as well as the mechanical stability possible using low gelator loadings. Multicomponent gels formed from low molecular weight gelators allows one to access a wide variety of soft materials from a limited number of molecular components. The discoveries described in this thesis help advance the field of gelators and make steps toward predicting the properties of gels formed from them.

description: It has been demonstrated that acoustic-emission (AE), inspection of structures can offer advantages over other types of monitoring techniques in the detection of damage; namely, an increased sensitivity to damage, as well as an ability to localise its source. There are, however, numerous challenges associated with the analysis of AE data. One issue is the high sampling frequencies required to capture AE activity. In just a few seconds, a recording can generate very high volumes of data, of which a significant portion may be of little interest for analysis. Identifying the individual AE events in a recorded time-series is therefore a necessary procedure to reduce the size of the dataset. Another challenge that is also generally encountered in practice, is determining the sources of AE, which is an important exercise if one wishes to enhance the quality of the diagnostic scheme. In this paper, a state-of-the-art technique is presented that can automatically identify AE events, and simultaneously help in their characterisation from a probabilistic perspective. A nonparametric Bayesian approach, based on the Dirichlet process (DP), is employed to overcome some of the challenges associated with these tasks. Two main sets of AE data are considered in this work: (1) from a journal bearing in operation, and (2) from an Airbus A320 main landing gear subjected to fatigue testing.

description: We introduce a class of randomly time-changed fast mean-reverting stochastic volatility models and, using spectral theory and singular perturbation techniques, we derive an approximation for the prices of European options in this setting. Three examples of random time-changes are provided and the implied volatility surfaces induced by these time-changes are examined as a function of the model parameters. Three key features of our framework are that we are able to incorporate jumps into the price process of the underlying asset, allow for the leverage effect, and accommodate multiple factors of volatility, which operate on different time-scales.

description: Films of metal-insulator nanogranular composites M$_x$D$_{100-x}$ with different composition and percentage of metal and dielectric phases (M = Fe, Co, CoFeB; D = Al$_2$O$_3$, SiO$_2$, LiNbO$_3$; x $\approx$ 15-70 at.%) are investigated by magnetic resonance in a wide range of frequencies (f = 7-37 GHz) and temperatures (T = 4.2-360 K). In addition to the usual ferromagnetic resonance signal from an array of nanogranules, the experimental spectra contain an additional absorption peak, which we associate with the electron paramagnetic resonance (EPR) of Fe and Co ions dispersed in the insulating space between the granules. In contrast to the traditional EPR of Fe and Co ions in weakly doped non-magnetic matrices, the observed peak demonstrates a number of unusual properties, which we explain by the presence of magnetic interactions between ions and granules.
Essential self-adjointness of Wick squares in quasi-free Hadamard representations on curved spacetimes
Creators: name: Sanders, Ko
Publisher: name: arXiv
Year: 2010
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: We investigate whether a second order Wick polynomial T of a free scalar field, including derivatives, is essentially self-adjoint on the natural (Wightman) domain in a quasi-free (i.e. Fock space) Hadamard representation. We restrict our attention to the case where T is smeared with a test-function from a particular class S, namely the class of sums of squares of testfunctions. This class of smearing functions is smaller than the class of all non-negative testfunctions -- a fact which follows from Hilbert's Theorem. Exploiting the microlocal spectrum condition we prove that T is essentially self-adjoint if it is a Wick square (without derivatives). More generally we show that T is essentially self-adjoint if its compression to the one-particle Hilbert space is essentially self-adjoint. For the latter result we use Wüst's Theorem and an application of Konrady's trick in Fock space. In this more general case we also prove that one has some control over the spectral projections of T, by describing it as the strong graph limit of a sequence of essentially self-adjoint operators.

description: We present a version of acoustic black holes by using the principle of the Josephson effect. We find that in the case two superconductors $A$ and $B$ are separated by an insulating barrier, an acoustic black hole may be created in the middle region between the two superconductors. We discuss in detail how to describe an acoustic black hole in the Josephson junction and write the metric in the langauge of the superconducting electronics. Our final results infer that for big enough tunneling current and thickness of the junction, experimental verification of the Hawking temperature could be possible.

description: Resonant inelastic x-ray spectroscopy (RIXS) has emerged as an important tool to explore magnetism in two-dimensional (2D) antiferromagnet realized in strongly correlated materials. Here we consider the Heisenberg model with nearest and next nearest neighbor hopping relevant to the study of magnetic excitations of the cuprate family. We compute the RIXS cross-section within the ultra-short core-hole lifetime (UCL) expansion of the Kramers-Heisenberg scattering amplitude that allows perturbative solution within linear spin wave theory (LSWT). We report detailed results for both spin-conserving and non-conserving channels. Apart from the widely discussed single magnon and bimagnon contributions, we show that three-magnon contributions in the spin non-conserving channel are useful to explain certain features of the RIXS data for two-dimensional cuprates. We confirm the qualitative correctness of the LSWT conclusions for the three-magnon excitation with exact diagonalization. Our work puts constraints on the dispersion of the three-magnon in the Brillouin zone, opening new avenues for realizing higher modes of quasiparticles using RIXS.

description: Introduction: This study was undertaken to report long-term outcomes after laparoscopic Heller myotomies performed more than 15 years ago to determine if outcomes are salutary and durable, and support continued application of laparoscopic Heller myotomy as first-line therapy for achalasia.

Methods: With IRB approval, patients have been prospectively followed after Heller myotomy. Patients scored the frequency and severity of symptoms using a Likert scale (0=never/not bothersome to 10=always/very bothersome). Pre- and post-operative outcomes with Heller myotomy are compared. Data are presented as median or median (mean ± SD), where appropriate.

Results: 100 patients (55% men, age 48 years, BMI 24 kg/m2) underwent laparoscopic Heller myotomy prior to 2000. For all patients, follow-up is 10 years (10 ± 5.3); with myotomy, dysphagia frequency fell from 10 (9 ± 2.1) to 4 (4 ± 2.8) and dysphagia severity fell from 10 (9 ± 2.4) to 2 (3 ± 2.9) (p<0.001 for each) without the development of reflux related symptoms (e.g., heartburn) (Table). 29 patients were followed to death 7 years (7 ± 4.4) after Heller myotomy undertaken at age 71 years (69 ± 12.7), 55 patients are currently “lost to follow-up” after follow-up of 9 years (8 ± 4.03), and 16 patients are “currently followed” at 17 years (17 ± 1.1). Duration of follow-up did not impact the frequency or severity of symptoms (Table). 83% of patients are satisfied or very satisfied and 89% would have the operation again, knowing what they now know.

Conclusions:  Long-term follow-up after laparoscopic Heller myotomy documents patient satisfaction and durable symptomatic relief without troublesome new symptoms. Durable salutary benefits after laparoscopic Heller myotomy justify its continued application as first-line therapy for achalasia.

description: We study the $Z_{cs}(3985)$ and $Z_{cs}(4000)$ exotic states in the decays of $Λ_b$ baryons through a molecular scenario. In the final state interaction, the $Λ_b\to Λ_c^+ D_s^{(*)-}$ decays are followed by the $Λ_c^+ D_s^{(*)-}$ to $Z^-_{cs}p$ rescatterings via exchange of a $D^{(*)}$ meson. We predict a branching fraction of $(3.1^{+1.4}_{-2.6})\times 10^{-4}$ for $Λ_b\to Z^-_{cs}p$, which can be measured in the $Λ_b\to J/ψK^{(*)-}p$ decay. This study proposes a new approach to test the molecular model, and guides future experimental searches for the $Z_{cs}(3985)$ and $Z_{cs}(4000)$.

description: We consider the problem of secure communications over the two-way wiretap channel under a strong secrecy criterion. We improve existing results by developing an achievable region based on strategies that exploit both the interference at the eavesdropper's terminal and cooperation between legitimate users. We leverage the notion of channel resolvability for the multiple-access channel to analyze cooperative jamming and we show that the artificial noise created by cooperative jamming induces a source of common randomness that can be used for secret-key agreement. We illustrate the gain provided by this coding technique in the case of the Gaussian two-way wiretap channel, and we show significant improvements for some channel configurations.

description: A large family of new black hole solutions in 2+1-dimensional Einstein-Power-Maxwell (EPM) gravity with prescribed physical properties is derived. We show with particular examples that according to the power parameter k of the Maxwell field, the obtained solutions may be asymptotically flat for 1/21 in the vanishing cosmological constant limit. We study the thermodynamic properties of the solution with two different models and it is shown that thermodynamic quantities satisfy the first law. The behaviour of the heat capacity indicates that by employing the 1+1-dimensional dilaton analogy the local thermodynamic stability is satisfied.

Slicing Sets and Measures, and the Dimension of Exceptional Parameters

Subjects: subject: Classical Analysis and ODEs (math.CA)

description: We consider the problem of slicing a compact metric space Ωwith sets of the form π_λ^{-1}\{t\}, where the mappings π_λ \colon Ω\to \R, λ\in \R, are \emph{generalized projections}, introduced by Yuval Peres and Wilhelm Schlag in 2000. The basic question is: assuming that Ωhas Hausdorff dimension strictly greater than one, what is the dimension of the 'typical' slice π_λ^{-1}{t}, as the parameters λand t vary. In the special case of the mappings π_λ being orthogonal projections restricted to a compact set Ω\subset \R^{2}, the problem dates back to a 1954 paper by Marstrand: he proved that for almost every λthere exist positively many $t \in \R$ such that \dim π_λ^{-1}{t} = \dim Ω- 1. For generalized projections, the same result was obtained 50 years later by Järvenpää, Järvenpää and Niemelä. In this paper, we improve the previously existing estimates by replacing the phrase 'almost all λ' with a sharp bound for the dimension of the exceptional parameters.

description: It has been widely observed that there exists a fundamental trade-off between the minimum (Hamming) distance properties and the iterative decoding convergence behavior of turbo-like codes. While capacity achieving code ensembles typically are asymptotically bad in the sense that their minimum distance does not grow linearly with block length, and they therefore exhibit an error floor at moderate-to-high signal to noise ratios, asymptotically good codes usually converge further away from channel capacity. In this paper, we introduce the concept of tuned turbo codes, a family of asymptotically good hybrid concatenated code ensembles, where asymptotic minimum distance growth rates, convergence thresholds, and code rates can be traded-off using two tuning parameters, λ and μ. By decreasing λ, the asymptotic minimum distance growth rate is reduced in exchange for improved iterative decoding convergence behavior, while increasing λ raises the asymptotic minimum distance growth rate at the expense of worse convergence behavior, and thus the code performance can be tuned to fit the desired application. By decreasing μ, a similar tuning behavior can be achieved for higher rate code ensembles.

description: Monte Carlo integration is a widely used numerical method for approximating integrals, which is often computationally expensive. In recent years, quantum computing has shown promise for speeding up Monte Carlo integration, and several quantum algorithms have been proposed to achieve this goal. In this paper, we present an application of Quantum Machine Learning (QML) and Grover's amplification algorithm to build a new tool for estimating Monte Carlo integrals. Our method, which we call Quantum Fourier Iterative Amplitude Estimation (QFIAE), decomposes the target function into its Fourier series using a Parametrized Quantum Circuit (PQC), specifically a Quantum Neural Network (QNN), and then integrates each trigonometric component using Iterative Quantum Amplitude Estimation (IQAE). This approach builds on Fourier Quantum Monte Carlo Integration (FQMCI) method, which also decomposes the target function into its Fourier series, but QFIAE avoids the need for numerical integration of Fourier coefficients. This approach reduces the computational load while maintaining the quadratic speedup achieved by IQAE. To evaluate the performance of QFIAE, we apply it to a test function that corresponds with a particle physics scattering process and compare its accuracy with other quantum integration methods and the analytic result. Our results show that QFIAE achieves comparable accuracy while being suitable for execution on real hardware. We also demonstrate how the accuracy of QFIAE improves by increasing the number of terms in the Fourier series. In conclusion, QFIAE is a promising end-to-end quantum algorithm for Monte Carlo integrals that combines the power of PQC with Fourier analysis and IQAE to offer a new approach for efficiently approximating integrals with high accuracy.

How do trust and decentralization impact adoption? : an agent-based model for diffusion of blockchain-based COVID-19 contact tracing apps
Creators: name: Zhang, Jundong
Publisher: name: University of British Columbia
Year: 2023

description: Although contact tracing apps are effective in containing the impacts of COVID-19, their centralized management model cause significant user concerns about privacy and information security. Blockchain-based contact tracing apps have received increasing attention as a better alternative. However, the adoption of blockchain-based solutions is slow. This paper investigates how user perceptions and technical features of blockchain-based contact tracing apps individually and jointly influence users' adoption intention in the short and long term. The collection of apps and users is viewed as a Complex Adaptive System. An Agent-Based Modeling technique is adopted in this paper, where users are regarded as agents. In addition, agents are adaptive to the environment and interact with each other according to behavioral rules. Via a trust-centered lens, several simulation studies were conducted with different pre-determined parameters to investigate the impacts of various characteristics of users and solutions. Finally, survey-based validations and sensitivity analyses were conducted to validate the rationality of the model. The results show that both cognitive and emotional trusts of the users are positive and crucial to the adoption diffusion. Regarding app characteristics, compatibility level and scalability resistance could positively affect adoption. Moreover, service providers can choose to invest in highly connected communities. This study takes the first step to developing a dynamic diffusion model of blockchain-based COVID-19 contact tracing apps. In addition, it provides theoretical and practical implications to facilitate the implementation of blockchain-based solutions.

description: We propose to Transform Scene Graphs (TSG) into more descriptive captions. In TSG, we apply multi-head attention (MHA) to design the Graph Neural Network (GNN) for embedding scene graphs. After embedding, different graph embeddings contain diverse specific knowledge for generating the words with different part-of-speech, e.g., object/attribute embedding is good for generating nouns/adjectives. Motivated by this, we design a Mixture-of-Expert (MOE)-based decoder, where each expert is built on MHA, for discriminating the graph embeddings to generate different kinds of words. Since both the encoder and decoder are built based on the MHA, as a result, we construct a homogeneous encoder-decoder unlike the previous heterogeneous ones which usually apply Fully-Connected-based GNN and LSTM-based decoder. The homogeneous architecture enables us to unify the training configuration of the whole model instead of specifying different training strategies for diverse sub-networks as in the heterogeneous pipeline, which releases the training difficulty. Extensive experiments on the MS-COCO captioning benchmark validate the effectiveness of our TSG. The code is in: https://github.com/GaryJiajia/TSG.

description: This thesis describes applications of computer simulation and bioinformatics techniques in conjunction with experiments to understand various biological systems. In Chapter 2, we used molecular dynamics simulations to uncover the structural details of an experimentally observed interaction between the ALS-associated protein superoxide dismutase 1 (SOD1), and TNF receptor-associated factor 6. Residues present in their heterodimer binding interface were predicted through unbiased and metadynamics simulations and tested in cultured cells. In Chapter 3, we used a quick computational scan to identify two de novo mutations of SOD1, A89R and K128N that were expected to be destabilizing and stabilizing respectively. Expression in cell cultures and zebrafish confirmed that A89R produces pathologies similar to the ALS-associated mutant A4V, and that K128N is WT-like. Interestingly, unlike WT-SOD1, K128N rescued the aberrant phenotype of zebrafish motor neurons when coinjected with A4V-SOD1. To explain this, we used computational alchemy to calculate heterodimerization free energies for A4V-SOD1 with WT-SOD1 and K128N-SOD1, but could not confirm a "heterodimer-rescue" mechanism. In Chapter 4, we studied the conformational landscape of the SARS-CoV-2 spike protein. The conserved residues 980-990, normally buried under the receptor binding domain, have been reported to be transiently accessible to antibodies. Through umbrella sampling simulations we found that direct exposure of the epitope through dynamic motions is not a likely mechanism for this accessibility. Further, glycans play an important role in preventing such dynamics. During its normal function, this epitope undergoes a large-scale conformational change from a bent to an extended state. To aid development of a vaccine antigen containing the conserved fragment, we studied the free energy cost of this change and found that a bent pre-fusion-like conformation is preferred. Moving on from protein studies, in Chapter 5 we were interested in the biophysics of genome organization, and its evolution in early ancestors of all animals. The basal metazoan Mnemiopsis leidyi is well-suited for such studies but has not been standardized as a model organism. We developed protocols for laboratory culture of this organism, and obtained a highly contiguous reference genome for an inbred lineage.

description: The identification of microscopic models describing the low-energy properties of correlated materials has been a central goal of spectroscopic measurements. We demonstrate how 2D non-linear spectroscopy can be used to distinguish effective spin models whose linear responses show similar behavior. Motivated by recent experiments on the quasi-1D Ising magnet CoNb$_2$O$_6$, we focus on two proposed models, the ferromagnetic twisted Kitaev chain with bond dependent interactions and the transverse field Ising model. The dynamical spin structure factor probed in linear response displays similar broad spectra for both models from their fermionic domain wall excitations. In sharp contrast, the 2D non-linear spectra of the two models show clear qualitative differences: those of the twisted Kitaev model contain off-diagonal peaks originating from the bond dependent interactions and transitions between different fermion bands absent in the transverse field Ising model. We discuss the different signatures of spin fractionalization in integrable and non-integrable regimes of the models and their connection to experiments.

description: We compute the dark matter relic densities of neutralinos and axions in a supersymmetric model with a gauged anomalous U(1) symmetry, kinetically mixed with $U(1)_Y$ of hypercharge. The model is a variant of the USSM (the U(1) extended NMSSM), containing an extra U(1) symmetry and an extra singlet in the superpotential respect to the MSSM, where gauge invariance is restored by Peccei-Quinn interactions using a Stuckelberg multiplet. This approach introduces an axion (Im b) and a saxion (Re b) in the spectrum and generates an axino component for the neutralino. The Stuckelberg axion (Im b) develops a physical component (the gauged axion) after electroweak symmetry breaking. We classify all the interactions of the Lagrangian and perform a complete simulation study of the spectrum, determining the neutralino relic densities using micrOMEGAs. We discuss the phenomenological implications of the model analyzing mass values for the axion from the milli-eV to the MeV region. The possible scenarios that we analyze are significantly constrained by a combination of WMAP data, the exclusion limits from direct axion searches and the veto on late entropy release at the time of nucleosynthesis.

description: Atomic gases confined in curved geometries are characterized by distinctive features that are absent in their flat counterparts, such as periodic boundaries, local curvature, and nontrivial topologies. The recent experiments with shell-shaped quantum gases and the study of ring-shaped superfluids point out that the manifold of a quantum gas could soon become a controllable feature, thus allowing to address the fundamental study of curved many-body quantum systems. Here, we review the main geometries realized in the experiments, analyzing the theoretical and experimental status on their phase transitions and on the superfluid dynamics. In perspective, we delineate the study of vortices, the few-body physics, and the search for analog models in various curved geometries as the most promising research areas.

description: The distribution engendered by successive splitting of one point vortex are considered. The process of splitting a vortex in three using a reverse three-point vortex collapse course is analysed in great details and shown to be dissipative. A simple process of successive splitting is then defined and the resulting vorticity distribution and vortex populations are analysed.

description: We propose the operatorial form of Baxter's TQ-relations in a general form of the operatorial Bäcklund flow describing the nesting process for the inhomogeneous rational gl(K|M) quantum (super)spin chains with twisted periodic boundary conditions. The full set of Q-operators and T-operators on all levels of nesting is explicitly defined. The results are based on a generalization of the identities among the group characters and their group co-derivatives with respect to the twist matrix, found by one of the authors and P.Vieira [V.Kazakov and P.Vieira, JHEP 0810 (2008) 050 [arXiv:0711.2470]]. Our formalism, based on this new "master" identity, allows a systematic and rather straightforward derivation of the whole set of nested Bethe ansatz equations for the spectrum of quantum integrable spin chains, starting from the R-matrix.

description: Rapid access to accurate equation-of-state (EOS) data is crucial in the warm-dense matter regime, as it is employed in various applications, such as providing input for hydrodynamic codes to model inertial confinement fusion processes. In this study, we develop neural network models for predicting the EOS based on first-principles data. The first model utilizes basic physical properties, while the second model incorporates more sophisticated physical information, using output from average-atom calculations as features. Average-atom models are often noted for providing a reasonable balance of accuracy and speed; however, our comparison of average-atom models and higher-fidelity calculations shows that more accurate models are required in the warm-dense matter regime. Both the neural network models we propose, particularly the physics-enhanced one, demonstrate significant potential as accurate and efficient methods for computing EOS data in warm-dense matter.

description: Controlling marine vehicles in challenging environments is a complex task due to the presence of nonlinear hydrodynamics and uncertain external disturbances. Despite nonlinear model predictive control (MPC) showing potential in addressing these issues, its practical implementation is often constrained by computational limitations. In this paper, we propose an efficient controller for trajectory tracking of marine vehicles by employing a convex error-state MPC on the Lie group. By leveraging the inherent geometric properties of the Lie group, we can construct globally valid error dynamics and formulate a quadratic programming-based optimization problem. Our proposed MPC demonstrates effectiveness in trajectory tracking through extensive-numerical simulations, including scenarios involving ocean currents. Notably, our method substantially reduces computation time compared to nonlinear MPC, making it well-suited for real-time control applications with long prediction horizons or involving small marine vehicles.

description: A numerical approach is employed to explain transport characteristics in realistic, quantum Hall based Aharonov-Bohm interferometers. First, the spatial distribution of incompressible strips, and thus the current channels, are obtained applying a self-consistent Thomas-Fermi method to a realistic heterostructure under quantized Hall conditions. Second, the time-dependent Schrödinger equation is solved for electrons injected in the current channels. Distinctive Aharonov-Bohm oscillations are found as a function of the magnetic flux. The oscillation amplitude strongly depends on the mutual distance between the transport channels and on their width. At an optimal distance the amplitude and thus the interchannel transport is maximized, which determines the maximum visibility condition. On the other hand, the transport is fully suppressed at magnetic fields corresponding to half-integer flux quanta. The results confirm the applicability of realistic Aharonov-Bohm interferometers as controllable current switches.
