description: Experimental and numerical studies of the magnetic field dependence of the specific heat and magnetization of single crystals of CsNiF3 have been performed at 2.4 K, 2.9 K, and 4.2 K in magnetic fields up to 9 T oriented perpendicular to the easy plane. The experimental results confirm the presence of the theoretically predicted double peak structure in the specific heat arising from the formation of nonlinear spin modes. The demagnetizing effects are found to be negligible, and the overall agreement between the data and numerical predictions is better than reported for the case when the magnetic field was oriented in the easy plane. Demagnetizing effects might play a role in generating the difference observed between theory and experiment in previous work analyzing the excess specific heat using the sine-Gordon model.

description: We analyze the chargino contributions to the CP violating ratio $ε^{\prime}/ε$ in the left-right supersymmetric model. We study the possibility that these contributions alone can saturate the experimental value of $ε^{\prime}/ε$. We derive conservative bounds on supersymmetric flavor violation parameters in the up squark LL, RR, LR and RL sectors, using the mass insertion approximation. While the LL bounds are found to be consistent with the MSSM values, the LR constraints are new and much stronger.

description: We consider solutions of the word equation $X_1^2 \dotsm X_n^2 = (X_1 \dotsm X_n)^2$ such that the squares $X_i^2$ are minimal squares found in optimal squareful infinite words. We apply a method developed by the second author for studying word equations and prove that there are exactly two families of solutions: reversed standard words and words obtained from reversed standard words by a simple substitution scheme. A particular and remarkable consequence is that a word $w$ is a standard word if and only if its reversal is a solution to the word equation and $\gcd(|w|, |w|_1) = 1$. This result can be interpreted as a yet another characterization for standard Sturmian words. We apply our results to the symbolic square root map $\sqrt{\cdot}$ studied by the first author and M. A. Whiteland. We prove that if the language of a minimal subshift $Ω$ contains infinitely many solutions to the word equation, then either $Ω$ is Sturmian and $\sqrt{\cdot}$-invariant or $Ω$ is a so-called SL-subshift and not $\sqrt{\cdot}$-invariant. This result is progress towards proving the conjecture that a minimal and $\sqrt{\cdot}$-invariant subshift is necessarily Sturmian.

description: Firstly, we completely determine the self-similar Hausdorff spectrum of the group of $q$-adic automorphisms where $q$ is a prime power, answering a question of Grigorchuk. Indeed, we take a further step and completely determine its Hausdorff spectra restricted to the most important subclasses of self-similar groups, providing examples differing drastically from the previously known ones in the literature. Our proof relies on a new explicit formula for the computation of the Hausdorff dimension of closed self-similar groups and a generalization of iterated permutational wreath products.
 Secondly, we provide for every prime $p$ the first examples of just infinite branch pro-$p$ groups with zero Hausdorff dimension in $Γ_p$, giving strong evidence against a well-known conjecture of Boston.

description: We use models of stellar angular momentum evolution to determine ages for $\sim500$ stars in the APOGEE-\textit{Kepler} Cool Dwarfs sample. We focus on lower main-sequence stars, where other age-dating tools become ineffective. Our age distributions are compared to those derived from asteroseismic and giant samples and solar analogs. We are able to recover gyrochronological ages for old, lower-main-sequence stars, a remarkable improvement over prior work in hotter stars. Under our model assumptions, our ages have a median relative uncertainty of $14\%$, comparable to the age precision inferred for more massive stars using traditional methods. We investigate trends of galactic $α$-enhancement with age, finding evidence of a detection threshold between the age of the oldest $α$-poor stars and that of the bulk $α$-rich population. We argue that gyrochronology is an effective tool reaching ages of 10--12 Gyr in K- and early M-dwarfs. Finally, we present the first effort to quantify the impact of detailed abundance patterns on rotational evolution. We estimate a $\sim15\%$ bias in age for cool, $α$-enhanced (+ 0.4 dex) stars when standard solar-abundance-pattern rotational models are used for age inference, rather than models that appropriately account for $α$-enrichment.

description: We report a flare on the M9 dwarf DENIS 104814.7-395606.1, whose mass places it directly at the hydrogen burning limit. The event was observed in a spectral sequence during 1.3 hours. Line shifts to bluer wavelengths were detected in H alpha, H beta, and in the Na D lines, indicating mass motions. In addition we detect a flux enhancement on the blue side of the two Balmer lines in the last spectrum of our series. We interpret this as rising gas cloud with a projected velocity of about 100 km/s which may lead to mass ejection. The higher Balmer lines H gamma to H 8 are not seen due to our instrumental setup, but in the last spectrum there is strong evidence for H 9 being in emission.

description: Modern agriculture in Australia is often viewed as utilitarian and neutral on the one hand, or as a destroyer of 'pristine' environments on the other. It is either a story of steady progress in technique and technology, of 'science with its sleeves rolled up', or one of disastrous environmental consequences of industrialisation and capitalism. Scientific agriculture in Australia is taken for granted as being about food, fibre and income, but these have not been its main purposes. Agriculture's social and cultural purposes, and its environmental purposes, have been more important factors shaping its advocacy and development. Broken Country explores how the explosion of knowledge in biology in the nineteenth and early twentieth centuries - entangled with cultural ideas about civilisation, inheritance, race and population - shaped modern agriculture in Australia. It examines the wider history of knowledge for agriculture and place through the story of the Darling and Macquarie River country after European agriculture first came to the semi-arid plains of western New South Wales. As the pastoral industry began collapsing at the end of the nineteenth century, colonial governments pushed agriculture based on scientific principles as a solution to anxieties about the effects of space and distance on civilisation, as well as a means to address the exploitative environmental culture of settlers on the inland plains. In the 1940s large engineering projects and the integration of the management of people and environment was supposed to address the social and environmental problems of the 1930s agricultural crisis, after World War II, it became a means of defending Australia from a hungry Asia and for preventing the spread of communism. How successful has scientific agriculture been in achieving these big fixes? How has it fared as the main vehicle for the changing environmental management philosophies of wise use, balance, integration, optimisation, sustainability, and recently, resilience? Is it a triumphant project that has made incredible increases in yield to feed a burgeoning global population, or has it left us precariously at risk of ecological collapse and left a billion people starving? What do scientific agriculture's cultural foundations say about our relationships with our environment each other, and what is Australia's role in this system?

description: The $s-$wave meson-baryon scattering is analyzed for the isospin-strangeness $I=1/2, S=0$ and $I=0,S=-1$ sectors, in a Bethe-Salpeter coupled channel formalism incorporating Chiral Symmetry. For both sectors, four channels have been considered: $πN$, $ηN$, $K Λ$, $K Σ$ and $πΣ$, $\bar K N$, $ηΛ$, $K Ξ$, respectively. The needed two particle irreducible matrix amplitudes are taken from lowest order Chiral Perturbation Theory in a relativistic formalism. There appear undetermined low energy constants, as a consequence of the renormalization of the amplitudes, which are obtained from fits to the available data: elastic $πN $ phase-shifts, $π^- p \to ηn$ and $π^- p \to K^0 Λ$ cross sections and to $πΣ\toπΣ$ mass-spectrum, the elastic $\bar K N \to \bar K N$ and $ \bar K N\to πΣ$ $t$--matrices and to the $ K^- p \to ηΛ$ cross section data. The position and residues of the complex poles in the second Riemann sheet of the scattering amplitude determine masses, widths and branching ratios of the $S_{11}-$ $N$(1535) and $-N$(1650) and $S_{01}-$ $Λ$(1405) and $-Λ$(1670) resonances, in reasonable agreement with experiment. A good overall description of data, from threshold up to around 2 GeV is achieved despite the fact that three-body channels have not been explicitly included.

Bachama Folktales and the Radio today
Creators: name: Solomon, Racheal
Publisher: name: Zenodo
Year: 2023

description: Folktales in African societies act as repositories of moral, social, religious instructions as well as traditions primarily narrated by grandparents and parents through time This paper, using the functionalist theory, examines how Orature survives through its relationships with electronic mass media in the form of radio. To collect data, a survey questionnaire, three semi-structured interviews, and analysis of a radio program were employed. Sixty respondents (aged 20-50 years) provided responses to the questionnaire; the interviews were held with two community members alongside an acting director to gain their perspective of how radio has impacted the narration of traditional folktales.Findings indicate that Orature such as the Bachama(Bwatiye) Folktales are like fossils that refuse to die; rather they adapt and adjust, and still re-emerge as formidable means of entertainment and education. Narrators on radio put efforts to ensure that certain characteristics found in the primary orality are still maintained in the secondary narrations. There is a need to preserve oral traditions, as these oral traditions are gradually declining and the mass media provides an opportunity to reach to a wider range of audiences, which will promote preservation.

description: Recent advances in prototypical learning have shown remarkable potential to provide useful decision interpretations associating activation maps and predictions with class-specific training prototypes. Such prototypical learning has been well-studied for various single-label diseases, but for quite relevant and more challenging multi-label diagnosis, where multiple diseases are often concurrent within an image, existing prototypical learning models struggle to obtain meaningful activation maps and effective class prototypes due to the entanglement of the multiple diseases. In this paper, we present a novel Cross- and Intra-image Prototypical Learning (CIPL) framework, for accurate multi-label disease diagnosis and interpretation from medical images. CIPL takes advantage of common cross-image semantics to disentangle the multiple diseases when learning the prototypes, allowing a comprehensive understanding of complicated pathological lesions. Furthermore, we propose a new two-level alignment-based regularisation strategy that effectively leverages consistent intra-image information to enhance interpretation robustness and predictive performance. Extensive experiments show that our CIPL attains the state-of-the-art (SOTA) classification accuracy in two public multi-label benchmarks of disease diagnosis: thoracic radiography and fundus images. Quantitative interpretability results show that CIPL also has superiority in weakly-supervised thoracic disease localisation over other leading saliency- and prototype-based explanation methods.

description: We study the $O(N)$ model in dimension three (3$d$) at large and infinite $N$ and show that the line of fixed points found at $N=\infty$ --the Bardeen-Moshe-Bander (BMB) line-- has an intriguing origin at finite $N$. The large $N$ limit that allows us to find the BMB line must be taken on particular trajectories in the $(d,N)$-plane: $d=3-α/N$ and not at fixed dimension $d=3$. Our study also reveals that the known BMB line is only half of the true line of fixed points, the second half being made of singular fixed points. The potentials of these singular fixed points show a cusp for a finite value of the field and their finite $N$ counterparts a boundary layer.

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: I present an observational review of the five currently known accretion-driven millisecond X-ray pulsars. A prominent place in this review is given to SAX J1808.4-3658; it was the first such system discovered and currently four outbursts have been observed from this source. This makes SAX J1808.4-3658 the best studied example of the group. Its most recent outburst in October 2002 is of particular interest because of the discovery of two simultaneous kilohertz quasi-periodic oscillations and nearly coherent oscillations during type-I X-ray bursts. This is the first time that such phenomena are observed in a system for which the neutron star spin frequency is exactly known. The other four systems were discovered within the last two years and only limited results have been published. Since new exiting results are to be expected in the future for all five sources, this review will only represent a snap-shot of the current observational knowledge of accretion-driven millisecond X-ray pulsars.

description: This work presents the implementation, numerical examples and experimental convergence study of first- and second-order optimization methods applied to one-dimensional periodic gratings. Through boundary integral equations and shape derivatives, the profile of a grating is optimized such that it maximizes the diffraction efficiency for given diffraction modes for transverse electric polarization. We provide a thorough comparison of three different optimization methods: a first-order method (gradient descent); a second-order approach based on a Newton iteration, where the usual Newton step is replaced by taking the absolute value of the eigenvalues given by the spectral decomposition of the Hessian matrix to deal with non-convexity; and the Broyden-Fletcher-Goldfarb-Shanno (BFGS) algorithm, a quasi-Newton method. Numerical examples are provided to validate our claims. Moreover, two grating profiles are designed for high efficiency in the Littrow configuration and then compared to a high efficiency commercial grating. Conclusions and recommendations, derived from the numerical experiments, are provided as well as future research avenues.

zdjela supe (a bowl of soup) : rebuilding through community, culture, and materiality
Creators: name: Kisin, Renata
Publisher: name: The University of British Columbia
Year: 2022

description: Postwar reconstruction relies heavily on foreign investment and external actors. While necessary for immediate crisis response, these approaches often lack cultural, social, and material sensitivities which continue to alter post-conflict societies well after the dust has settled. By examining the architectural ruins of war and their potential for reuse, this thesis speculates on what culture-led rebuilding might look like for those whose culture was once under attack. Examining the region of former Yugoslavia, and the city of Sarajevo more specifically, it is evident that postwar reconstruction efforts often contribute to the erasure of collective memory in favour of serving particular narratives. This thesis argues for a reconceptualization of post-conflict reconstruction whereby local actors are the agents in transforming the damaged built environment. By making use of ruins, the layering of history tells a complete story and a bottom-up approach allows residents to literally build a better future for themselves.
Full wave models in linear time invariant signal processing

description: Full wave models have assumed a niche role in signal processing due to their complexity, limitation to (mostly) empty space, often absent sources, lack of intuition, and insufficient integration with the theory of signal processing in general. This thesis removes these shortcomings and derives closed form solutions for source generated wave fields in the presence of arbitrarily shaped objects. This is made possible by including absorption effects, substantially augmenting the eigenfunction expansion method, and combining both with linear system theory. The result is a generic closed form state space model and impulse response formula which reduces wave models to linear filters, both theoretically and practically, yet contains only elementary functions. The reasons for this is the explicit use of rectangular regions which also furnishes a considerably simpler derivation of some existing results like dimensionality scaling laws because the corresponding Fourier series naturally connects dimensionality with signal bandwidth. Furthermore, the thesis uses the Fourier series to link boundary value problems with information theory and shows how to store and retrieve information in a wave field, exemplified by an elastic rubber string. Despite simplifying some existing results, the main focus is on source generated wave fields and their connection to linear filters, as underlined with closed form solutions for waves in a wave guide, around the human head, in an urban street area, and more. These examples also emphasise how the results from this thesis allow everyone with a signal processing - but not necessarily a Partial Differential Equation (PDE) - background to use full wave models because these have been reduced to linear filters with a closed form impulse- and frequency response. This makes full wave models less intimidating to approach, adds intuition, and reduces many complex wave problems to simpler ones, as shown for the source localisation problem in highly reverberant environments. The thesis also extends the reach of signal processing beyond standard wave problems to include linearised water models, bio-heat transfer, chemical diffusion, and more in the same fashion.
Dynamical Detection of Level Repulsion in the One-Particle Aubry-André Model

description: The analysis of level statistics provides a primary method to detect signatures of chaos in the quantum domain. However, for experiments with ion traps and cold atoms, the energy levels are not as easily accessible as the dynamics. In this work, we discuss how properties of the spectrum that are usually associated with chaos can be directly detected from the evolution of the number operator in the one-dimensional, noninteracting Aubry-André model. Both the quantity and the model are studied in experiments with cold atoms. We consider a single-particle and system sizes experimentally reachable. By varying the disorder strength within values below the critical point of the model, level statistics similar to those found in random matrix theory are obtained. Dynamically, these properties of the spectrum are manifested in the form of a dip below the equilibration point of the number operator. This feature emerges at times that are experimentally accessible. This work is a contribution to a special issue dedicated to Shmuel Fishman.

description: In this work we present a theoretical investigation into an antiferromagnetically coupled spin system, specifically ${\rm Cu}_{3}-X$ ($\mathrm{X=As,Sb}$), which exhibits an isosceles triangular configuration or slightly distorted equilateral triangular configuration, as previously identified in reference {[}Phys. Rev. Lett. \textbf{96}, 107202 (2006){]}. This system can be effectively represented by the Heisenberg model on a triangular structure, taking into account the exchange interaction, the Dzyaloshinskii-Moriya interaction, g-factors and external magnetic field, as delineated in the aforementioned reference. By using numerical approach we explore both zero-temperature and finite-temperature behaviors of a ${\rm Cu}_{3}$-like antiferromagnetically coupled spin system. At zero temperature, the system displays a 1/3 quasi-plateau magnetization, when the magnetic field is varied. Moreover, we place particular emphasis on magnetic properties including magnetization, magnetic susceptibility, entropy, and specific heat at finite temperatures. Furthermore, we investigate the magnetocaloric effect as a function of an externally imposed magnetic field, oriented both parallel and perpendicular to the plane of the triangular structure. Interestingly, these configurations demonstrate remarkably similar behavior for both orientations of the magnetic field. Our investigation also includes an analysis of the adiabatic curve, the Grüneisen parameter, and the variation in entropy when applied or removed the magnetic field. The magnetocaloric effect is found to be more prominent in low the temperature region, typically at $T\sim1$K, for both parallel and perpendicular magnetic fields at $\sim4.5$T and $\sim5$T, respectively.

description: We discuss implications of recent experimental data for B decays into two pseudoscalar mesons, with emphasis on those with $η$ and $η'$ in the final states. Applying a U-spin argument, we show that tree and penguin amplitudes, both in $B^+ \to π^+ η$ and in $B^+ \to π^+ η'$, are of comparable magnitudes. Nontrivial relative weak and strong phases between the tree-level amplitudes and penguin-loop amplitudes in the $B^{\pm} \to π^{\pm} η$ modes are extracted. We predict possible values for the averaged branching ratio and CP asymmetry of the $B^{\pm} \to π^{\pm} η'$ modes. We test the assumption of a singlet-penguin amplitude with the same weak and strong phases as the QCD penguin in explaining the large branching ratios of $η' K$ modes, and show that it is consistent with current branching ratio and CP asymmetry data of the $B^+ \to (π^0, η, η') K^+$ modes. We also show that the strong phases of the singlet-penguin and tree-level amplitudes can be extracted with further input of electroweak penguin contributions and a sufficiently well-known branching ratio of the $ηK^+$ mode. Using SU(3) flavor symmetry, we also estimate required data samples to detect modes that have not yet been seen.

description: We have developed a numerical framework for a full solution of the relativistic Boltzmann equations for the quark-gluon matter using the multiple Graphics Processing Units (GPUs) on distributed clusters. Including all the $2 \to 2$ scattering processes of 3-flavor quarks and gluons, we compute the time evolution of distribution functions in both coordinate and momentum spaces for the cases of pure gluons, quarks and the mixture of quarks and gluons. By introducing a symmetrical sampling method on GPUs which ensures the particle number conservation, our framework is able to perform the space-time evolution of quark-gluon system towards thermal equilibrium with high performance. We also observe that the gluons naturally accumulate in the soft region at the early time, which may indicate the gluon condensation.

description: The DDI Discovery Vocabulary represents the most important parts of DDI-Codebook and DDI-Lifecycle in the Web of Data covering the discovery use case. Now, researchers have the possibility to publish and link their data and metadata in the Linked Open Data Cloud. In various software projects in the statistical domain these basic DDI concepts are reused to a large extent. Thus, the DDI Discovery Vocabulary could serve as a common abstract data model for all of these software projects. As software products have individual requirements, the common abstract data model has to be customized in form of individual data models. The projects MISSY and StarDat are used to document variable and study information, respectively. They could serve as representative use cases to show how abstract data models and project-specific data models cover the requirements of these kind of projects. This presentation gives an overview of the project's software architecture and the interaction of their layers and components. In addition, the succeeding talk about the detailed technical perspective (on use-case-driven challenges for software architectures to document study and variable information) describes how to implement the proposed software architecture and how to implement different persistence formats like DDI-XML, DDI-RDF, and relational databases.

description: We present a study of the ultra-faint Milky Way dwarf satellite galaxy Tucana II using deep photometry from the 1.3m SkyMapper telescope at Siding Spring Observatory, Australia. The SkyMapper filter-set contains a metallicity-sensitive intermediate-band $v$ filter covering the prominent Ca II K feature at 3933.7A. When combined with photometry from the SkyMapper $u, g$, and $i$ filters, we demonstrate that $v$ band photometry can be used to obtain stellar metallicities with a precision of $\sim0.20$dex when [Fe/H] $> -2.5$, and $\sim0.34$dex when [Fe/H] $< -2.5$. Since the $u$ and $v$ filters bracket the Balmer Jump at 3646A, we also find that the filter-set can be used to derive surface gravities. We thus derive photometric metallicities and surface gravities for all stars down to a magnitude of $g\sim20$ within $\sim$75 arcminutes of Tucana II. Photometric metallicity and surface gravity cuts remove nearly all foreground contamination. By incorporating Gaia proper motions, we derive quantitative membership probabilities which recover all known members on the red giant branch of Tucana II. Additionally, we identify multiple likely new members in the center of the system and candidate members several half-light radii from the center of the system. Finally, we present a metallicity distribution function derived from the photometric metallicities of likely Tucana II members. This result demonstrates the utility of wide-field imaging with the SkyMapper filter-set in studying UFDs, and in general, low surface brightness populations of metal-poor stars. Upcoming work will clarify the membership status of several distant stars identified as candidate members of Tucana II.

description: "No free lunch" results state the impossibility of obtaining meaningful bounds on the error of a learning algorithm without prior assumptions and modelling. Some models are expensive (strong assumptions, such as as subgaussian tails), others are cheap (simply finite variance). As it is well known, the more you pay, the more you get: in other words, the most expensive models yield the more interesting bounds. Recent advances in robust statistics have investigated procedures to obtain tight bounds while keeping the cost minimal. The present paper explores and exhibits what the limits are for obtaining tight PAC-Bayes bounds in a robust setting for cheap models, addressing the question: is PAC-Bayes good value for money?
Pion damping width from SU(2) x SU(2) NJL model

description: Within the framework of the NJL model, we investigate the modification of the pion damping width in a hot pion gas for temperatures ranging from 0 to 180 MeV. The pion is found to broaden noticeably at T > 60 MeV. Near the chiral phase transition T ~ 180 MeV, the pion width is saturated and amounts to 70 MeV. The main contribution to the width comes from pion-pion collisions. Other contributions are found negligibly small.

description: We introduce several-dozen experimentally-found invariants of Poncelet N-periodics in the confocal ellipse pair (Elliptic Billiard). Recall this family is fully defined by two integrals of motion (linear and angular momentum), so any "new" invariants are dependent upon them. Nevertheless, proving them may require sophisticated methods. We reference some two-dozen proofs already contributed. We hope this article will motivate contributions for those still lacking proof.

Calculation of the Critical Temperature for 2- and 3-Dimensional Ising Models and for 2-Dimensional Potts Models Using the Transfer Matrix Method

description: A new graphical method is developed to calculate the critical temperature of 2- and 3-dimensional Ising models as well as that of the 2-dimensional Potts models. This method is based on the transfer matrix method and using the limited lattice for the calculation. The reduced internal energy per site has been accurately calculated for different 2-D Ising and Potts models using different size-limited lattices. All calculated energies intersect at a single point when plotted versus the reduced temperature. The reduced temperature at the intersection is 0.4407, 0.2746, and 0.6585 for the square, triangular, and honeycombs Ising lattices and 1.0050, 0.6309, and 1.4848 for the square, triangular, and honeycombs Potts lattices, respectively. These values are exactly the same as the critical temperatures reported in the literature, except for the honeycomb Potts lattice. For the two-dimensional Ising model, we have shown that the existence of such an intersection point is due to the duality relation. The method is then extended to the simple cubic Ising model, in which the intersection point is found to be dependent on the lattice sizes. We have found a linear relation between the lattice size and the intersection point. This relation is used to obtain the critical temperature of the unlimited simple cubic lattice. The obtained result, 0.221(2), is in a good agreement with the accurate value of 0.22165 reported by others.
