description: Data sonification-mapping data variables to auditory variables, such as pitch or volume-is used for data accessibility, scientific exploration, and data-driven art (e.g., museum exhibitions) among others. While a substantial amount of research has been made on effective and intuitive sonification design, software support is not commensurate, limiting researchers from fully exploring its capabilities. We contribute Erie, a declarative grammar for data sonification, that enables abstractly expressing auditory mappings. Erie supports specifying extensible tone designs (e.g., periodic wave, sampling, frequency/amplitude modulation synthesizers), various encoding channels, auditory legends, and composition options like sequencing and overlaying. Using standard Web Audio and Web Speech APIs, we provide an Erie compiler for web environments. We demonstrate the expressiveness and feasibility of Erie by replicating research prototypes presented by prior work and provide a sonification design gallery. We discuss future steps to extend Erie toward other audio computing environments and support interactive data sonification.

We start giving a brief introduction of the GDE in General Relativity in the case of the standard cosmology. Next we generalize the GDE for metric f(R) gravity using again the FLRW metric. A generalization of the Mattig relation is also obtained. Finally we give and equivalent expression to the Dyer-Roeder equation in General Relativity in the context of f(R) gravity.

description: In view of the recent progress in experiments on charge transport through various Josephson junctions made out of graphene, we have made a careful comparison between the theory and some of the available experimental results. Within the framework of a transfer matrix approach, we have first analytically derived the spectrum of Andreev bound states (ABS) in a superconductor -graphene-superconductor (SGS) junction for a wide range of experimentally relevant parameters. We have particularly considered the case of monolayer graphene (MLG). The theoretical results can account for both the retro Andreev reflection (RAR) and the specular Andreev reflection (SAR) in the relevant parameter range. Using the ABS spectrum we have evaluated the current through such junctions and the junction conductance from the analytically derived expressions at different bias voltages for a range of other system parameters directly taken from the experimental works. These theoretical results have then been compared with experimental results. Evaluated current and the conductance show scaling behaviour with change in the junction length and agree well with the experimental results. In the relevant parameter regime where the SAR process is dominant, the calculated values of the current and the conductivity have been found much lower than the corresponding values observed when the RAR process is dominant.

description: Higher-order scalar field models in two dimensions, including the $ϕ^8$ model, have been researched. It has been shown that for some special cases of the minima positions of the potential, the explicit kink solutions can be found. However, in physical applications, it is very important to know all the explicit solutions of a model for any minima position. In the present study, with the help of some deformation functions, we have shown that higher-order scalar field theories can be obtained with explicit kinks. In particular, we introduced two deformation functions that, when applied to the well known $ϕ^4$ and $ϕ^6$ models, produce modified $ϕ^8$ and $ϕ^{10}$ models, respectively, with all their explicit kink-like solutions which depend on a single parameter. Since this parameter controls the position of the minima of the potential, we have found interesting new solutions in many distinct cases. We have also studied the kink mass, the behavior of the excitation spectra and several kink-antikink collisions for these two new modified models. The collision outcome is determined by the initial configuration, specifically the sequence in which the kink-antikink and antikink-kink pairings emerge. Another interesting finding is the suppression of resonance windows, which may be explained by the presence of a set of internal modes in the model.

description: The main characteristics of panic disorder (PD) include recurrent panic attacks and persistent worry, accompanied by other physical and cognitive symptoms. While recent studies have revealed that gut bacteria play an important role in anxiety and depression, little is known about the relationship between oral microbiota and PD. Therefore, the objective of this study was to explore a possible correlation between oral microbiota and PD. We conducted 16S rRNA sequencing to compare differences in the oral microbiota of patients with PD (n = 26) and healthy controls (n = 40). Patients with PD exhibited higher alpha diversity (abundance and evenness) in their oral microbiota than healthy controls, while analysis of beta diversity revealed that the two groups differed in microbial community composition. Moreover, the relative abundance of 61 genera differed between them. Overall, PD resulted in distinct oral microbial profiles that could be potential diagnostic markers and therapeutic targets.

description: We investigate the effects of an oscillating gas filament on the dynamics of its embedded stellar clusters. Motivated by recent observational constraints, we model the host gas filament as a cylindrically symmetrical potential, and the star cluster as a Plummer sphere. In the model, the motion of the filament will produce star ejections from the cluster, leaving star cluster remnants that can be classified into four categories: a) Filament Associated clusters, which retain most of their particles (stars) inside the cluster and inside the filament; b) destroyed clusters, where almost no stars are left inside the filament, and there is no surviving bound cluster; c) ejected clusters, that leave almost no particles in the filament, since the cluster leaves the gas filament; and d) transition clusters, corresponding to those clusters that remain in the filament, but that lose a significant fraction of particles due to ejections induced by filament oscillation. Our numerical investigation predicts that the Orion Nebula Cluster is in the process of being ejected, after which it will most likely disperse into the field. This scenario is consistent with observations which indicate that the Orion Nebula Cluster is expanding, and somewhat displaced from the Integral Shaped Filament ridgeline.

description: In this study, we explore the new wormhole solutions in the framework of new modified $f(R,L_m)$ gravity. To obtain a characteristic wormhole solution, we use anisotropic matter distribution and a specific form of energy density. As second adopt the isotropic case with a linear EoS relation as a general technique for the system and discuss several physical attributes of the system under the wormhole geometry. Detailed analytical and graphical discussion about the matter contents via energy conditions is discussed. In both cases, the shape function of wormhole geometry satisfies the required conditions. Several interesting points have evolved from the entire investigation along with the features of the exotic matter within the wormhole geometry. Finally, we have concluding remarks.

Thixotropy and slip of model kaolinite hybrid and oil tailings suspensions
Creators: name: Piette, Jourdain
Publisher: name: University of British Columbia
Year: 2022

description: In this thesis, two clay colloidal systems are studied and rheologically characterized. The first is a suspension of kaolinite particles with and without the addition of cationic and anionic surfactant, namely Cetyl Trimethyl Ammonium Bromide (CTAB), and sodium dodecyl sulfate (SDS). The second system is Mature Fine Tailings (MFT), a by-product of oil sands bitumen extraction. The former system is studied as a model system to understand the more complex behavior of oil tailings. The steady-shear behavior of the kaolinite suspensions with surfactant is explored above and below the critical micelle concentration (CMC). SDS was shown to weaken the network structure at concentrations below the CMC. At concentrations greater than the CMC, SDS causes an increase in the yield stress due to network formation of micellar structures The yield stress was found to increase monotonically with CTAB concentration, which can be explained by the improved network strength. Both kaolinite and kaolinite-CTAB systems were found to exhibit thixotropic and anti-thixotropic behavior at short and longtime scales respectively. The rheological characteristics of mature fine tailings (MFTs) were examined in steady shear flow. MFT samples exhibited thixotropic behavior as well as apparent slip, which was suppressed by using sandpaper of grit 80 (200 μm) at the wall of the parallel-plate geometry. The real yield stress of MFTs with shear-thinning behavior was retrieved after fitting to a Herschel–Bulkley equation. The presence of bitumen remaining in the MFTs (up to 2 wt. %) suppressed the apparent slip to a substantial extent due to the immobilization of the particles at the interface. Finally, the effect of temperature on the rheology of both suspension systems was studied in detail over the range of 0–50 °C, showing a minimum viscosity and yield stress at about 20 °C, demonstrating a non-monotonic increase with the increase in temperature. This was found to be due to the increase of kaolinite particle charge with increase of temperature.

description: We describe a new, microscopic model for diffusion that captures diffusion induced fluctuations at scales where the concept of concentration gives way to discrete particles. We show that in the limit as the number of particles $N \to \infty$, our model is equivalent to the classical stochastic diffusion equation (SDE). We test our new model and the SDE against Langevin dynamics in numerical simulations, and show that our model successfully reproduces the correct ensemble statistics, while the classical model fails.

description: Embedded real-time devices for monitoring, controlling, and collaboration purposes in cyber-physical systems are now commonly equipped with IP networking capabilities. However, the reception and processing of IP packets generates workloads in unpredictable frequencies as networks are outside of a developer's control and difficult to anticipate, especially when networks are connected to the internet. As of now, embedded network controllers and IP stacks are not designed for real-time capabilities, even when used in real-time environments and operating systems. Our work focuses on real-time aware packet reception from open network connections, without a real-time networking infrastructure. This article presents two experimentally evaluated modifications to the IP processing subsystem and embedded network interface controllers of constrained IoT devices. The first, our software approach, introduces early packet classification and priority-aware processing in the network driver. In our experiments this allowed the network subsystem to remain active at a seven-fold increase in network traffic load before disabling the receive interrupts as a last resort. The second, our hardware approach, makes changes to the network interface controller, applying interrupt moderation based on real-time priorities to minimize the number of network-generated interrupts. Furthermore, this article provides an outlook on how the software and hardware approaches can be combined in a co-designed packet receive architecture.

description: In this paper, we study the $μ$-variant of the periodic $b$-equation and show that this equation can be realized as a metric Euler equation on the Lie group $\Diff^{\infty}(§)$ if and only if $b=2$ (for which it becomes the $μ$-Camassa-Holm equation). In this case, the inertia operator generating the metric on $\Diff^{\infty}(§)$ is given by $L=μ-\partial_x^2$. In contrast, the $μ$-Degasperis-Procesi equation (obtained for $b=3$) is not a metric Euler equation on $\Diff^{\infty}(§)$ for any regular inertia operator $A\in\mathcal L_{\text{is}}^{\text{sym}}(C^{\infty}(§))$. The paper generalizes some recent results of [J. Escher and B. Kolev, DOI 10.1007/s00209-010-0778-2], [J. Escher and J. Seiler, J. Math. Phys. 51 (2010), 053101.1-053101.6] and [B.

description: In this paper, we study two-component versions of the periodic Hunter-Saxton equation and its $μ$-variant. Considering both equations as a geodesic flow on the semidirect product of the circle diffeomorphism group $\Diff(§)$ with a space of scalar functions on $§$ we show that both equations are locally well-posed. The main result of the paper is that the sectional curvature associated with the 2HS is constant and positive and that 2$μ$HS allows for a large subspace of positive sectional curvature. The issues of this paper are related to some of the results for 2CH and 2DP presented in [J. Escher, M. Kohlmann, and J. Lenells, J. Geom. Phys. 61 (2011), 436-452].

description: In order to explain the main characteristics of the observed population of extrasolar planets and the giant planets in the Solar System, we need to get a clear understanding of which are the initial conditions that allowed their formation. To this end we develop a semi-analytical model for computing planetary systems formation based on the core instability model for the gas accretion of the embryos and the oligarchic growth regime for the accretion of the solid cores. With this model we explore not only different initial discs profiles motivated by similarity solutions for viscous accretion discs, but we also consider different initial conditions to generate a variety of planetary systems assuming a large range of discs masses and sizes according to the last results in protoplanetary discs observations. We form a large population of planetary systems in order to explore the effects in the formation of assuming different discs and also the effects of type I and II regimes of planetary migration, which were found to play fundamental role in reproducing the distribution of observed exoplanets. Our results show that the observed population of exoplanets and the giant planets in the Solar System are well represented when considering a surface density profile with a power law in the inner part characterized by an exponent of -1, which represents a softer profile when compared with the case most similar to the MMSN model case.

description: We discuss the multiband energy release in a model of a collapsing galactic nucleus, and we try to interpret the unique super-long cosmic gamma-ray event Swift J164449.3+573451 (GRB 110328A by early classification) in this scenario. Neutron stars and stellar-mass black holes can form evolutionary a compact self-gravitating subsystem in the galactic center. Collisions and merges of these stellar remnants during an avalanche contraction and collapse of the cluster core can produce powerful events in different bands due to several mechanisms. Collisions of neutron stars and stellar-mass black holes can generate gamma-ray bursts (GRBs) similar to the ordinary models of short GRB origin. The bright peaks during the first two days may also be a consequence of multiple matter supply (due to matter release in the collisions) and accretion onto the forming supermassive black hole. Numerous smaller peaks and later quasi-steady radiation can arise from gravitational lensing, late accretion of gas onto the supermassive black hole, and from particle acceleration by shock waves. Even if this model will not reproduce exactly all the Swift J164449.3+573451 properties in future observations, such collapses of galactic nuclei can be available for detection in other events.

description: An outbreak with a remarkable Listeria monocytogenes clone causing 163 cases of non-invasive listeriosis occurred in Germany in 2015. Core genome multi locus sequence typing grouped non-invasive outbreak isolates and isolates obtained from related food samples into a single cluster, but clearly separated genetically close isolates obtained from invasive listeriosis cases. A comparative genomic approach identified a premature stop codon in the chiB gene, encoding one of the two L. monocytogenes chitinases, which clustered with disease outcome. Correction of this premature stop codon in one representative gastroenteritis outbreak isolate restored chitinase production, but effects in infection experiments were not found. While the exact role of chitinases in virulence of L. monocytogenes is still not fully understood, our results now clearly show that ChiB-derived activity is not required to establish L. monocytogenes gastroenteritis in humans. This limits a possible role of ChiB in human listeriosis to later steps of the infection.
Towards the quantum S-matrix of the Pohlmeyer reduced version of AdS_5 x S^5 superstring theory

description: We investigate the structure of the quantum S-matrix for perturbative excitations of the Pohlmeyer reduced version of the AdS_5 x S^5 superstring following arXiv:0912.2958. The reduced theory is a fermionic extension of a gauged WZW model with an integrable potential. We use as an input the result of the one-loop perturbative scattering amplitude computation and an analogy with simpler reduced AdS_n x S^n theories with n=2,3. The n=2 theory is equivalent to the N=2 2-d supersymmetric sine-Gordon model for which the exact quantum S-matrix is known. In the n=3 case the one-loop perturbative S-matrix, improved by a contribution of a local counterterm, satisfies the group factorization property and the Yang-Baxter equation, and reveals the existence of a novel quantum-deformed 2-d supersymmetry which is not manifest in the action. The one-loop perturbative S-matrix of the reduced AdS_5 x S^5 theory has the group factorisation property but does not satisfy the Yang-Baxter equation suggesting some subtlety with the realisation of quantum integrability. As a possible resolution, we propose that the S-matrix of this theory may be identified with the quantum-deformed [psu(2|2)]^2 x R^2 symmetric R-matrix constructed in arXiv:1002.1097. We conjecture the exact all-order form of this S-matrix and discuss its possible relation to the perturbative S-matrix defined by the path integral. As in the AdS_3 x S^3 case the symmetry of the S-matrix may be interpreted as an extended quantum-deformed 2-d supersymmetry.

Daughter of a vice president : the double life of Louisa Burr
Creators: name: Maillard, Mary Jane Ward
Publisher: name: University of British Columbia
Year: 2022

description: There is no documentary evidence that Louisa Burr (c.1784-1878) and her better-known brother John Pierre Burr (1792-1864) are the biracial children of U.S. Vice President Aaron Burr. The oral history of their parentage, however, is persuasive and consistent over a period of 230 years. Descendants have continued to tell their children and grandchildren of their descent from Aaron Burr through as many as eight generations. Drawing on archival research, fiction, memoir, biography, news clippings, and naming practices, as valid evidence that supports oral history and situates it within the context of historical events that had the effect of silencing, I will recover the biography of one woman of color and pose research questions for the ongoing search for her mother. Louisa Burr’s various Philadelphia house addresses throughout her life, the social connections among Aaron Burr and his associates in 1790s Philadelphia, and the political activities of Louisa Burr’s family and friends in the first half of the nineteenth century, all provide circumstantial evidence that supplements the oral family history and demonstrates that Aaron Burr’s family of color not only participated in the growth of the Early Republic but made significant contributions to early African American activism, culture, and literature. The complex portrait of Louisa Burr that emerges is one of a biracial Northern woman who lived simultaneously—and apparently harmoniously—in both abolitionist and Southern-sympathizing households. Louisa Burr’s double life, bound by conflicting loyalties, gave her a rare ground-view perspective of the sectional crisis—a perspective that we can only now appreciate through the traces of refracted light emanating from her family and friends.

description: We present a sub-matrix update algorithm for the continuous-time auxiliary field method that allows the simulation of large lattice and impurity problems. The algorithm takes optimal advantage of modern CPU architectures by consistently using matrix instead of vector operations, resulting in a speedup of a factor of $\approx 8$ and thereby allowing access to larger systems and lower temperature. We illustrate the power of our algorithm at the example of a cluster dynamical mean field simulation of the Néel transition in the three-dimensional Hubbard model, where we show momentum dependent self-energies for clusters with up to 100 sites.
Augusta Bagiennorum, la sua eventuale orientazione astronomica e l'anno di fondazione sotto Augusto

description: L’articolo discute un possibile orientamento astronomico della colonia di Augusta Bagiennorum, sita nel comune di Bene Vagienna. Nel caso di questa colonia, la direzione del sorgere del sole non può esser chiamata in causa, né per la direzione del decumano né per quella del cardo. Resta un sola possibilità, allineare il cardo alla direzione più meridionale possibile di levata della luna. Questo accadeva attorno al 24 a.C., quando Ottaviano era già diventato Augusto ed attorno al 5 a.C.. Se si assume che la direzione del cardo sia stata determinata con un allineamento astronomico, secundum coelum quindi, si potrebbe arrivare a datare la fondazione della colonia attorno al 24 a.C. o al 5 a.C.. E’ anche però vero che l’orientazione potrebbe essere stata fatta secundum naturam, ossia secondo la natura del luogo, e quindi la datazione dovrebbe essere determinata solo attraverso dati storici ed archeologici. Un’analisi storica, ci porta a propendere ad una fondazione tra il 6 ed il 4 a.C., un periodo di tempo anche in ottimo accordo coi dati astronomici.

description: We derive conditions under which random sequences of polarizations (two-point symmetrizations) converge almost surely to the symmetric decreasing rearrangement. The parameters for the polarizations are independent random variables whose distributions need not be uniform. The proof of convergence hinges on an estimate for the expected distance from the limit that also yields a bound on the rate of convergence. In the special case of i.i.d. sequences, we obtain almost sure convergence even for polarizations chosen at random from suitable small sets. As corollaries, we find bounds on the rate of convergence of Steiner symmetrizations that require no convexity assumptions, and show that full rotational symmetry can be achieved by randomly alternating Steiner symmetrization in a finite number of directions that satisfy an explicit non-degeneracy condition. We also present some negative results on the rate of convergence and give examples where convergence fails.

description: AbsThis study delves into the emerging field of entrepreneurship education in the performing arts, aiming to investigate current practices and evaluate the effectiveness of entrepreneurial endeavors within this domain. Focusing on Nigerian graduate and undergraduate prospective entrepreneurs, commonly referred to as theatrepreneurs, who pursue careers in drama, dancing, script writing, and other performing arts disciplines. The research utilizes qualitative methods. Forty purposefully selected respondents were interviewed, employing a mediated interview approach to identify theatrepreneurs' characteristics, motivations, and the significant challenges they encounter in their professional and entrepreneurial journeys. The findings demonstrate that participants opt for the performing arts primarily for personal career development rather than financial incentives. They highlight the benefits of talent development, confidence building, and professional growth. Nevertheless, the study identifies major obstacles such as time management, financial constraints, adaptation to the performing arts environment, unethical practices, and personal style, which significantly affect career development. Despite these challenges, respondents express optimism about the future of the profession. Based on the study's outcomes, it is recommended to introduce entrepreneurship education programs that nurture students' abilities to think creatively, reflectively, strategically, and analytically about their artistic practices. Such initiatives would further enhance professional career development within the performing arts industry.

description: We study single-crystal CeCoIn5 with uniaxial pressure up to 3.97 kbar applied along the c-axis. We find a non-linear dependence of the superconducting transition temperature Tc on pressure, with a maximum close to 2 kbar. The transition also broadens significantly as pressure increases. We discuss the temperature dependence in terms of the general trend that Tc decreases in anisotropic heavy-fermion compounds as they move towards three-dimensional behavior.

description: Representing human performance at high-fidelity is an essential building block in diverse applications, such as film production, computer games or videoconferencing. To close the gap to production-level quality, we introduce HumanRF, a 4D dynamic neural scene representation that captures full-body appearance in motion from multi-view video input, and enables playback from novel, unseen viewpoints. Our novel representation acts as a dynamic video encoding that captures fine details at high compression rates by factorizing space-time into a temporal matrix-vector decomposition. This allows us to obtain temporally coherent reconstructions of human actors for long sequences, while representing high-resolution details even in the context of challenging motion. While most research focuses on synthesizing at resolutions of 4MP or lower, we address the challenge of operating at 12MP. To this end, we introduce ActorsHQ, a novel multi-view dataset that provides 12MP footage from 160 cameras for 16 sequences with high-fidelity, per-frame mesh reconstructions. We demonstrate challenges that emerge from using such high-resolution data and show that our newly introduced HumanRF effectively leverages this data, making a significant step towards production-level quality novel view synthesis.

description: This research explores how Development Education and Global Learning (DEGL) is conceptualised and informed by theory in the context of practitioners working in Development Education Centres (DECs) in England. Whilst the literature exploring DEGL has grown significantly in recent years, very little of this has focused specifically on the perspective of practitioners. Furthermore, a perception prevails that practice remains under-theorised and lacks a coherent conceptual base, contributing to ongoing marginalisation of DECs. Informed by Critical Grounded Theory, the research analyses data obtained through a series of focus groups. These were designed to engage practitioners in a process of collaborative reflexivity which involved them overtly in the process of interpreting data and the implications for their work. Findings highlight the way practitioners conceptualise DEGL as a process of enabling change at individual level, with the potential for transformative and wider social change. This reflects the shift towards process-orientated and pedagogical approaches seen in the literature. It also reveals a complex interplay of tensions between personal motivations and values, theoretical influences and the social, political and discursive contexts in which DECs’ operate. More significantly, by exploring the emphasis on DEGL as a practice and, drawing on wider literature on professional practice knowledge, evidence was found of practitioners engaging with DEGL through embodied and knowing practice. This challenged assumptions about a theory-practice divide and opened up new insights into the ways theory can support evidence of growing alignment between theory, critical pedagogy and practice. Drawing these insights together, it was possible to see how DECs might realise their potential as catalysts for change across the organisational and contextual spaces for their work. However, this also depends upon developing their practice and its relationship with knowledge, and their collective capacity, through a community of practice.

description: Background: Spinal cord injuries can have profound long-term consequences. However, less is known about the experiences of people with incomplete spinal cord injuries who can ambulate. Objectives: 1) To identify the needs and strengths of people with incomplete spinal cord injury who can ambulate and explore potential supports, services, and programs that would help them in the community. 2) To examine associations between subjective quality of life and other socio-demographic variables in this population and to explore differences in experiences of people with different levels of quality of life (i.e., low, moderate, and high). Materials and methods: Study 1, was a qualitative descriptive study, and study 2 was a mixed-method study. Semi-structured interviews and standardized measures of function, health, mobility, and life satisfaction were used as the main means of data collection. In study 1 quantitative data were used descriptively, and in study 2, participants were categorized into three levels of quality of life, and the experiences of participants in these groups were explored quantitatively and qualitatively. Results: The 24 participants were 55 years old on average, with 54% being male. In study 1, we identified three themes: (1) ‘I really couldn’t go there’, described the physical and social barriers experienced by participants (2) ‘In this netherworld’ revealed participant’s desire for greater social understanding of incomplete spinal cord injury, and (3) ‘I just don’t quit’, displayed the perseverance that participants demonstrated following their injury. In study 2, the quantitative portion indicated that the variables male sex, having attended rehabilitation, and being married were strongly associated with increased quality of life. The qualitative portion revealed how people with a low quality of life felt that the neighborhood-built environment was not supportive. People with a low and moderate level of quality of life reported feeling devalued by able-bodied people and reported that their mobility was deteriorating over time. Conclusion: The study findings emphasize how changes to the built and social environment are needed to improve accessibility and promote the inclusion of people with incomplete spinal cord injuries who can ambulate.
