description: In 1542, the first Europeans entered the territory of the Caddo, the indigenous peoples of northeastern Texas and adjacent areas. Over the next few centuries, the Caddo would be drawn into new economic, social, and cultural connections with both European and indigenous newcomers, connecting them to the growing “Atlantic world”. At the same time as they were drawn into the Atlantic world, the Caddo maintained much older and deeper connections with indigenous communities surrounding them. Despite the dramatic changes European colonialism brought to their homeland, the Caddo retained sovereignty, continuing to govern themselves and their lands. This paper seeks to explore how the Caddo were connected to the world around them, both before and after colonization, and to determine how the Caddo responded to and navigated the changes brought by the European invasion. To do so, I examine a variety of historical sources, including written European sources, modern-day archaeological data, and Caddo oral history, all of which document the era through different lenses and offer insight into Caddo connections and changes across time.

description: The interplay between parasites and their hosts is found in all kinds of species and plays an important role in understanding the principles of evolution and coevolution. Usually, the different genotypes of hosts and parasites oscillate in their abundances. The well-established theory of oscillatory Red Queen dynamics proposes an ongoing change in frequencies of the different types within each species. So far, it is unclear in which way Red Queen dynamics persists with more than two types of hosts and parasites. In our analysis, an arbitrary number of types within two species are examined in a deterministic framework with constant or changing population size. This general framework allows for analytical solutions for internal fixed points and their stability. For more than two species, apparently chaotic dynamics has been reported. Here we show that even for two species, once more than two types are considered per species, irregular dynamics in their frequencies can be observed in the long run. The nature of the dynamics depends strongly on the initial configuration of the system; the usual regular Red Queen oscillations are only observed in some parts of the parameter region.

description: We propose unsupervised representation learning and feature extraction from dendrograms. The commonly used Minimax distance measures correspond to building a dendrogram with single linkage criterion, with defining specific forms of a level function and a distance function over that. Therefore, we extend this method to arbitrary dendrograms. We develop a generalized framework wherein different distance measures and representations can be inferred from different types of dendrograms, level functions and distance functions. Via an appropriate embedding, we compute a vector-based representation of the inferred distances, in order to enable many numerical machine learning algorithms to employ such distances. Then, to address the model selection problem, we study the aggregation of different dendrogram-based distances respectively in solution space and in representation space in the spirit of deep representations. In the first approach, for example for the clustering problem, we build a graph with positive and negative edge weights according to the consistency of the clustering labels of different objects among different solutions, in the context of ensemble methods. Then, we use an efficient variant of correlation clustering to produce the final clusters. In the second approach, we investigate the combination of different distances and features sequentially in the spirit of multi-layered architectures to obtain the final features. Finally, we demonstrate the effectiveness of our approach via several numerical studies.

description: We propose a novel approach for trip prediction by analyzing user's trip histories. We augment users' (self-) trip histories by adding 'similar' trips from other users, which could be informative and useful for predicting future trips for a given user. This also helps to cope with noisy or sparse trip histories, where the self-history by itself does not provide a reliable prediction of future trips. We show empirical evidence that by enriching the users' trip histories with additional trips, one can improve the prediction error by 15%-40%, evaluated on multiple subsets of the Nancy2012 dataset. This real-world dataset is collected from public transportation ticket validations in the city of Nancy, France. Our prediction tool is a central component of a trip simulator system designed to analyze the functionality of public transportation in the city of Nancy.

description: We present two methods for determining the significance of a stochastic gravitational-wave (GW) background affecting a pulsar-timing array, where detection is based on evidence for quadrupolar spatial correlations between pulsars. Rather than constructing noise simulations, we eliminate the GWB spatial correlations in the true datasets to assess detection significance with all real data features intact. In our first method, we perform random phase shifts in the signal-model basis functions. This phase shifting eliminates signal phase coherence between pulsars, while keeping the statistical properties of the pulsar timing residuals intact. We then explore a method to null correlations between pulsars by using a "scrambled" overlap-reduction function in the signal model for the array. This scrambled function is orthogonal to what we expect of a real GW background signal. We demonstrate the efficacy of these methods using Bayesian model selection on a set of simulated datasets that contain a stochastic GW signal, timing noise, undiagnosed glitches, and uncertainties in the Solar system ephemeris. Finally, we introduce an overarching formalism under which these two techniques are naturally linked. These methods are immediately applicable to all current pulsar-timing array datasets, and should become standard tools for future analyses.

Such CI statements correspond to determinantal conditions on a matrix whose entries are probabilities of events involving the observed random variables. We focus on an example that generalizes the CI ideals of the intersection axiom. In this example, the minimal primes are again determinantal ideals, which is not true in general.

description: Standard agglomerative clustering suggests establishing a new reliable linkage at every step. However, in order to provide adaptive, density-consistent and flexible solutions, we study extracting all the reliable linkages at each step, instead of the smallest one. Such a strategy can be applied with all common criteria for agglomerative hierarchical clustering. We also study that this strategy with the single linkage criterion yields a minimum spanning tree algorithm. We perform experiments on several real-world datasets to demonstrate the performance of this strategy compared to the standard alternative.

description: Traditional network embedding primarily focuses on learning a continuous vector representation for each node, preserving network structure and/or node content information, such that off-the-shelf machine learning algorithms can be easily applied to the vector-format node representations for network analysis. However, the learned continuous vector representations are inefficient for large-scale similarity search, which often involves finding nearest neighbors measured by distance or similarity in a continuous vector space. In this paper, we propose a search efficient binary network embedding algorithm called BinaryNE to learn a binary code for each node, by simultaneously modeling node context relations and node attribute relations through a three-layer neural network. BinaryNE learns binary node representations through a stochastic gradient descent based online learning algorithm. The learned binary encoding not only reduces memory usage to represent each node, but also allows fast bit-wise comparisons to support faster node similarity search than using Euclidean distance or other distance measures. Extensive experiments and comparisons demonstrate that BinaryNE not only delivers more than 25 times faster search speed, but also provides comparable or better search quality than traditional continuous vector based network embedding methods. The binary codes learned by BinaryNE also render competitive performance on node classification and node clustering tasks.

description: Propagation-based X-ray phase contrast enables nanoscale imaging of biological tissue by probing not only the attenuation, but also the real part of the refractive index of the sample. Since only intensities of diffracted waves can be measured, the main mathematical challenge consists in a phase-retrieval problem in the near-field regime. We treat an often used linearized version of this problem known as contract transfer function model. Surprisingly, this inverse problem turns out to be well-posed assuming only a compact support of the imaged object. Moreover, we establish bounds on the Lipschitz stability constant. In general this constant grows exponentially with the Fresnel number of the imaging setup. However, both for homogeneous objects, characterized by a fixed ratio of the induced refractive phase shifts and attenuation, and in the case of measurements at two distances, a much more favorable algebraic dependence on the Fresnel number can be shown. In some cases we establish order optimality of our estimates.

Comments: The species is distributed for most of the territory of Chile between the provinces of Choapa and Magallanes (González 2006). The Tierra del Fuego record needs to be verified.
Summary: The Coccinellidae fauna of the Isla Grande de Tierra del Fuego is composed by eight species, seven of them natives (one possibly endemic) and one introduced. Six species are shared with nearby territories including the Magallanes province. Only two species reach areas of Central Chile.
Note: Brèthes (1925) mentioned many species from “Valle del Lago Blanco, Patagonia”. Even if that locality exists near Porvenir in the Isla Grande de Tierra del Fuego, it seems more likely that the real locality corresponds to Lago Blanco, in Chubut, Argentina, as it is considered by Gordon (1994) and against what is suggested by Zúñiga-Reinoso (2011). That is why the species mentioned by Brèthes are not included here.

Unsupervised Representation Learning with Minimax Distance Measures

description: We investigate the use of Minimax distances to extract in a nonparametric way the features that capture the unknown underlying patterns and structures in the data. We develop a general-purpose and computationally efficient framework to employ Minimax distances with many machine learning methods that perform on numerical data. We study both computing the pairwise Minimax distances for all pairs of objects and as well as computing the Minimax distances of all the objects to/from a fixed (test) object. We first efficiently compute the pairwise Minimax distances between the objects, using the equivalence of Minimax distances over a graph and over a minimum spanning tree constructed on that. Then, we perform an embedding of the pairwise Minimax distances into a new vector space, such that their squared Euclidean distances in the new space equal to the pairwise Minimax distances in the original space. We also study the case of having multiple pairwise Minimax matrices, instead of a single one. Thereby, we propose an embedding via first summing up the centered matrices and then performing an eigenvalue decomposition to obtain the relevant features. In the following, we study computing Minimax distances from a fixed (test) object which can be used for instance in K-nearest neighbor search. Similar to the case of all-pair pairwise Minimax distances, we develop an efficient and general-purpose algorithm that is applicable with any arbitrary base distance measure. Moreover, we investigate in detail the edges selected by the Minimax distances and thereby explore the ability of Minimax distances in detecting outlier objects. Finally, for each setting, we perform several experiments to demonstrate the effectiveness of our framework.

description: Structural variants are large-scale genome rearrangement events, such as chromosomal inversions, duplications, and deletions, that can lead to innovative evolution that is not possible with point mutations. They can be especially important for microbial speciation and pathogenesis. We developed and tested an algorithm to detect newly evolved structural variants in microbial genomes from paired-end sequencing data. The method looks for read pairs with anomalous distances or orientations between where the two reads map to a reference genome. Then, it scores putative predictions using a statistical model trained on read pairs spanning normal positions in the chromosome. A computational pipeline for carrying out this analysis was implemented in R. The code was tested on genome sequencing data from a population of bacteria from the Lenski Long-Term Evolution Experiment with Escherichia coli that evolved to colonize a new nutrient niche through tandemly duplicating a region of the chromosome. This code could be integrated into the open-source breseq mutation prediction pipeline in the future to improve its ability to detect structural variants.

description: Double Weyl nodes are topologically protected band crossing points which carry chiral charge $\pm2$. They are stabilized by $C_{4}$ point group symmetry and are predicted to occur in $\mathrm{SrSi_{2}}$ or $\mathrm{HgCr_{2}Se_{4}}$. We study their stability and physical properties in the presence of a disorder potential. We investigate the density of states and the quantum transport properties at the nodal point. We find that, in contrast to their counterparts with unit chiral charge, double Weyl nodes are unstable to any finite amount of disorder and give rise to a diffusive phase, in agreement with predictions of Goswami and Nevidomskyy [Phys. Rev. B 92, 214504 (2015)] and Bera, Sau, and Roy [Phys. Rev. B 93, 201302(R) (2016)]. However, for finite system sizes a crossover between pseudodiffusive and diffusive quantum transport can be observed.

description: We study the collective oscillations of three-dimensional Bose-Einstein condensates (BECs) excited by a vortex ring. We identify independent, integrated, and stationary modes of the center-of-mass oscillation of the condensate with respect to the vortex ring movement. We show that the oscillation amplitude {of the center-of-mass of the condensate} depends strongly on the initial radius of the vortex ring, the inter-atomic interaction, and the aspect ration of the trap, while the oscillation frequency is fixed and equal to the frequency of the harmonic trap in the direction of the ring movement. However, when applying Kelvin wave perturbations on the vortex ring, the center-of-mass oscillation of the BEC is changed nontrivially with respect to the perturbation modes, the long-scale perturbation strength as well as the wave number of the perturbations. The parity of the wave number of the Kelvin perturbations plays important role on the mode of the center-of-mass oscillation of the condensate.

description: The media coverage of migration has changed in significant ways to include a distinct narrative of mass migration. In this report, I conducted a comparative cross-national content analysis of national media within the United States and Mexico that focuses on the depiction of migrant caravans in news articles from October of 2018 to December of 2019. These newspaper articles were derived based on the word search of, “Migrant Caravan”, or its equivalent in Spanish, “Caravana Migrante”, from The New York Times and El Universal respectively. This analysis of national media across two countries and within fifteen months will follow the development of the 2018 Honduran Migrant Caravan within news articles both printed and available online. With this, I hope to demonstrate key differences in the depiction of mass migration in the form of migrant caravans and the implications of media coverage as a medium for the representation of migrants.

description: Critical probes of dark matter come from tests of its elastic scattering with nuclei. The results are typically assumed to be model-independent, meaning that the form of the potential need not be specified and that the cross sections on different nuclear targets can be simply related to the cross section on nucleons. For point-like spin-independent scattering, the assumed scaling relation is $σ_{χA} \propto A^2 μ_A^2 σ_{χN}\propto A^4 σ_{χN}$, where the $A^2$ comes from coherence and the $μ_A^2\simeq A^2 m_N^2$ from kinematics for $m_χ\gg m_A$. Here we calculate where model independence ends, i.e., where the cross section becomes so large that it violates its defining assumptions. We show that the assumed scaling relations generically fail for dark matter-nucleus cross sections $σ_{χA} \sim 10^{-32}-10^{-27}\;\text{cm}^2$, significantly below the geometric sizes of nuclei, and well within the regime probed by underground detectors. Last, we show on theoretical grounds, and in light of existing limits on light mediators, that point-like dark matter cannot have $σ_{χN}\gtrsim10^{-25}\;\text{cm}^2$, above which many claimed constraints originate from cosmology and astrophysics. The most viable way to have such large cross sections is composite dark matter, which introduces significant additional model dependence through the choice of form factor. All prior limits on dark matter with cross sections $σ_{χN}>10^{-32}\;\text{cm}^2$ with $m_χ\gtrsim 1\;\text{GeV}$ must therefore be re-evaluated and reinterpreted.

description: This three-year research project began in January 2014 and investigated whether, during the Victorian period, the professions formed a distinct self-sustaining social group with its own mores and values. The project looked at 16,000 individuals drawn from census data for Alnwick, Brighton, Bristol, Dundee, Greenock, Leeds, Merthyr Tydfil, Morpeth, and Winchester. The research project was funded by the UK Economic & Social Research Council and was based at the Universities of Oxford and Northumbria.
The degree of Competition in Ethiopian Banking Industry
Creators: name: Bethelhem, Melkamu
Publisher: name: National Academic Digital Repository of Ethiopia

description: This study tries to investigate competitive condition of Ethiopian banking industry based on 16 private banks using quarterly panel data over the period of 2013-2017. The study applies both structural and non-structural methods. The result of structural measures; Concentration Ratio and Herfindahl-Hirschman index confirm banking sector in Ethiopia moderately concentrated and decreasing from time to time. A modern empirical analysis based on the non-structural method developed by Panzar and Rosse (1987) regressions with fixed effects were used to calculate the H statistic. The H-statistic is estimated using both interest revenue and total revenue as dependant variables. As explanatory variables: three factor input prices, bank specific and macroeconomic control variables used. The result of non-structural model; Panzar-Rosse confirm banking industry operate under perfect competitive and the equilibrium test results confirm that the market is in long-run equilibrium but interest revenue based market is lower than non-interest based market, that is price competition is relatively low in Ethiopian banking sector. The bank revenue highly explained by price of fund than other input prices, that implying interest expense is the main element of variable cost among banks. The result of non-structural model also confirms the structural argument that concentration is not a proxy of market structural.

Miracles in March: A breakdown of the peripheral effects created by Cinderella teams in Men’s Division I College Basketball

description: The NCAA men’s college basketball tournament, also known as March Madness, is a collegiate sporting event that occurs for three weeks every March and April and is used to determine the men’s college basketball champion in the United States. Throughout the three weeks, teams who unexpectedly make deep runs into the tournament, arise and are dubbed Cinderella teams by the public. Through the unexpected nature of these runs, curiosity from outsiders of these schools arises and generates buzz around the school’s name and image. This buzz can be used in positive ways to leverage the schools and their basketball program’s shareholders into a healthier position financially and socially. The paths to these healthier positions created through Cinderella runs can come through changes in admissions and academic standings of the schools, financials, conference affiliation, media exposure, career paths of team personnel, and name-image-likeness rules among many other effects. Through these, a potential for recklessness and poor decisions by school executives is spotted in the false belief that sports and their effects are inherently good for all involved. As this is not true, these executives need to monitor how changes to their institutions are implemented after Cinderella runs whether that’s in regards to the allocation of funding or the overall image of the school among other things. Effects through these runs are something that is constantly evolving and have the potential to create additional impacts in the coming years in the NCAA men’s and women’s basketball tournaments through the NCAA Transformation Committee’s recommended changes.

description: L’objet de ce travail est d’analyser la contagion émotionnelle entre enseignant·e·s et élèves. Le but est de vérifier si cette transmission des émotions a un impact, ou non, sur l’engagement des élèves lors de cours d’éducation physique et de natation. Cette étude est menée avec des élèves de troisième et quatrième année HARMOS elle se base sur des analyses de six vidéos réalisées lors de cours d’éducation physique et de natation, grâce à des entretiens d’auto-confrontation menés par Madame Descoeudres, pour les deux premiers, puis par nous-mêmes, pour ceux restants. Il y a peu d’études menées jusqu’à présent au sujet de la contagion émotionnelle en classe et ses impacts sur les élèves, au niveau de l’engagement. C’est pourquoi, notre recherche a permis d’approfondir le sujet et de nous questionner quant à notre pratique de futures enseignantes. Ce sujet, qui est un enjeu majeur de l’école et souvent négligé, fait partie des objectifs à atteindre. En effet, tout comme l’affirme Ramseier (2021), « on ne peut pas faire l’économie de parler des émotions » (p.5).

description: Combinatorial trees can be used to represent genealogies of asexual individuals. These individuals can be endowed with birth and death times, to obtain a so-called `chronological tree'. In this work, we are interested in the continuum analogue of chronological trees in the setting of real trees. This leads us to consider totally ordered and measured trees, abbreviated as TOM trees. First, we define an adequate space of TOM trees and prove that under some mild conditions, every compact TOM tree can be represented in a unique way by a so-called contour function, which is right-continuous, admits limits from the left and has non-negative jumps. The appropriate notion of contour function is also studied in the case of locally compact TOM trees. Then we study the splitting property of (measures on) TOM trees which extends the notion of `splitting tree' studied in \cite{MR2599603}, where during her lifetime, each individual gives birth at constant rate to independent and identically distributed copies of herself. We prove that the contour function of a TOM tree satisfying the splitting property is associated to a spectrally positive Lévy process that is not a subordinator, both in the critical and subcritical cases of compact trees as well as in the supercritical case of locally compact trees.

On the Global Dynamics of an Electroencephalographic Mean Field Model of the Neocortex

description: This paper investigates the global dynamics of a mean field model of the electroencephalogram developed by Liley et al., 2002. The model is presented as a system of coupled ordinary and partial differential equations with periodic boundary conditions. Existence, uniqueness, and regularity of weak and strong solutions of the model are established in appropriate function spaces, and the associated initial-boundary value problems are proved to be well-posed. Sufficient conditions are developed for the phase spaces of the model to ensure nonnegativity of certain quantities in the model, as required by their biophysical interpretation. It is shown that the semigroups of weak and strong solution operators possess bounded absorbing sets for the entire range of biophysical values of the parameters of the model. Challenges towards establishing a global attractor for the model are discussed and it is shown that there exist parameter values for which the constructed semidynamical systems do not possess a compact global attractor due to the lack of the asymptotic compactness property. Finally, using the theoretical results of the paper, instructive insights are provided into the complexity of the behavior of the model and computational analysis of the model.

description: In a representation of a graph $G$ as an edge intersection graph of paths on a grid (EPG) every vertex of $G$ is represented by a path on a grid and two paths share a grid edge iff the corresponding vertices are adjacent. In a monotonic EPG representation every path on the grid is ascending in both rows and columns. In a (monotonic) $B_k$-EPG representation every path on the grid has at most $k$ bends. The (monotonic) bend number $b(G)$ ($b^m(G)$) of a graph $G$ is the smallest natural number $k$ for which there exists a (monotonic) $B_k$-EPG representation of $G$. In this paper we deal with the monotonic bend number of outerplanar graphs and show that $b^m(G)\leqslant 2$ holds for every outerplanar graph $G$. Moreover, we characterize the maximal outerplanar graphs and the cacti with (monotonic) bend number equal to $0$, $1$ and $2$ in terms of forbidden induced subgraphs. As a byproduct we obtain low-degree polynomial time algorithms to construct (monotonic) EPG representations with the smallest possible number of bends for maximal outerplanar graphs and cacti.
