description: The dramatic adoption of Bitcoin and other cryptocurrencies in the USA has revolutionized the financial landscape and provided unprecedented investment and transaction efficiency opportunities. The prime objective of this research project is to develop machine learning algorithms capable of effectively identifying and tracking suspicious activity in Bitcoin wallet transactions. With high-tech analysis, the study aims to create a model with a feature for identifying trends and outliers that can expose illicit activity. The current study specifically focuses on Bitcoin transaction information in America, with a strong emphasis placed on the importance of knowing about the immediate environment in and through which such transactions pass through. The dataset is composed of in-depth Bitcoin wallet transactional information, including important factors such as transaction values, timestamps, network flows, and addresses for wallets. All entries in the dataset expose information about financial transactions between wallets, including received and sent transactions, and such information is significant for analysis and trends that can represent suspicious activity. This study deployed three accredited algorithms, most notably, Logistic Regression, Random Forest, and Support Vector Machines. In retrospect, Random Forest emerged as the best model with the highest F1 Score, showcasing its ability to handle non-linear relationships in the data. Insights revealed significant patterns in wallet activity, such as the correlation between unredeemed transactions and final balances. The application of machine algorithms in tracking cryptocurrencies is a tool for creating transparent and secure U.S. markets.

description: Tras la publicación en su totalidad en acceso abierto en 2022 en DraCor (Fisher et al 2019) bajo el nombre CalDraCor, la codificación en formato TEI de un corpus de 205 obras teatrales de Calderón de la Barca abrió nuevos caminos para la investigación del Siglo de Oro con métodos digitales, incluyendo el análisis cuantitativo (p.e., Ehrlicher et al 2020). Sin embargo, el desarrollo de nuevas preguntas de investigación ha generado la necesidad de un enriquecimiento del corpus más allá de la codificación original. A modo de ejemplo, este póster se centrará en la codificación TEI para el análisis de las redes sociales. Presentaremos la metodología que desarrollamos para realizar la segmentación de actos en escenas a partir de las acotaciones que indican entradas y salidas de personajes a fin de captar la interacción y discutiremos la plusvalía de la codificación TEI con ejemplos del teatro calderoniano.
description: Following the publication in full in open access in 2022 in DraCor (Fisher et al 2019) under the name CalDraCor, the TEI encoding of a corpus of 205 plays by Calderón de la Barca opened up new avenues for Golden Age research with digital methods, including quantitative analysis (e.g., Ehrlicher et al 2020). However, the development of new research questions has generated the need for an enrichment of the corpus beyond the original encoding. As an example, this poster will focus on TEI markup for social network analysis. We will present the methodology we developed for segmenting acts into scenes based on the stages indicating characters' entrances and exits in order to capture interaction and discuss the added value of TEI coding with examples from Calderón's theatre.

description: Dark matter coupled solely gravitationally can be produced through the decay of primordial black holes in the early universe. If the dark matter is lighter than the initial black hole temperature, it could be warm enough to be subject to structure formation constraints. In this paper we perform a more precise determination of these constraints. We first evaluate the dark matter phase-space distribution, without relying on the instantaneous decay approximation. We then interface this phase-space distribution with the Boltzmann code CLASS to extract the corresponding matter power spectrum, which we find to match closely those of warm dark matter models, albeit with a different dark matter mass. This mapping allows us to extract constraints from Lyman-$α$ data without the need to perform hydrodynamical simulations. We robustly rule out the possibility, consistent with previous analytic estimates, of primordial black holes having come to dominate the energy density of the universe and simultaneously given rise to all the DM through their decay. Consequences and implications for dark radiation and leptogenesis are also briefly discussed.

description: Manipulating spin currents in magnetic insulators is a key technology in spintronics. We theoretically study a simple inversion-asymmetric model of quantum antiferromagnets, where both the exchange interaction and the magnetic field are staggered. We calculate spin currents generated by external electric and magnetic fields by using a quantum master equation. We show that an ac electric field with amplitude $E_0$ leads, through exchange-interaction modulation, to the dc and second-harmonic spin currents proportional to $E_0^2$. We also show that dc and ac staggered magnetic fields $B_0$ generate the dc and ac spin currents proportional to $B_0$, respectively. We elucidate the mechanism by an exactly solvable model, and thereby propose the ways of spin current manipulation by electromagnetic fields.

description: In 2003, three U.S. banking regulatory agencies combined resources to revolutionize the collection, editing, storage, and dissemination of Commercial Bank Reports of Income and Condition. The regulatory agencies relied heavily on web-based technology and the XBRL transmission protocol. This paper will review the creation of an interagency data collection and dissemination facility. It will focus on the business problem that needed to be solved, the evolution of the technology that enabled the project, and what is XBRL and why was it selected as the transmission protocol. The paper will also review the challenges and benefits associated with using a standard transmission protocol versus creating a customized XML transmission facility.
Deep Collaborative Embedding for information cascade prediction

description: Recently, information cascade prediction has attracted increasing interest from researchers, but it is far from being well solved partly due to the three defects of the existing works. First, the existing works often assume an underlying information diffusion model, which is impractical in real world due to the complexity of information diffusion. Second, the existing works often ignore the prediction of the infection order, which also plays an important role in social network analysis. At last, the existing works often depend on the requirement of underlying diffusion networks which are likely unobservable in practice. In this paper, we aim at the prediction of both node infection and infection order without requirement of the knowledge about the underlying diffusion mechanism and the diffusion network, where the challenges are two-fold. The first is what cascading characteristics of nodes should be captured and how to capture them, and the second is that how to model the non-linear features of nodes in information cascades. To address these challenges, we propose a novel model called Deep Collaborative Embedding (DCE) for information cascade prediction, which can capture not only the node structural property but also two kinds of node cascading characteristics. We propose an auto-encoder based collaborative embedding framework to learn the node embeddings with cascade collaboration and node collaboration, in which way the non-linearity of information cascades can be effectively captured. The results of extensive experiments conducted on real-world datasets verify the effectiveness of our approach.
Pleasurably Painful : Biological horror as interpretation and design methodology for new aesthetic experiences in industrial ruins
Creators: name: Lam, Mason
Publisher: name: The University of British Columbia
Year: 2021

description: Pleasurably Painful is a conceptual exploration on the usage of biological horror as a lens to view and design industrial ruin sites. Suspended between stages of decline and redevelopment, these sites are largely regarded as worthless areas and are quick to be designed into parks or housing. However, this effaces the potential for new aesthetic experiences in industrial ruins, which can deepen our understanding of the complex urban landscape. The aesthetic of the post-industrial site is associated with the sublime, a landscape character which overwhelms the mind in a way that has been described as “pleasurably painful.” This project argues that horror fiction, an experience that is similarly pleasurably painful provides a way to both interpret and design industrial ruins. Furthermore, the subgenre of biological horror, which evokes the violation of natural laws, encapsulates the intricate interweaving of natural and cultural processes inherent to post-industrial sites. The experience of the industrial ruin landscape is simultaneously pleasure and pain, a contradictory hybrid of emotions that can be understood and appreciated through the lens of biological horror.
New approach to nonlinear electrodynamics: dualities as symmetries of interaction

description: We elaborate on the duality-symmetric nonlinear electrodynamics in a new formulation with auxiliary tensor fields. The Maxwell field strength appears only in bilinear terms of the corresponding generic Lagrangian, while the self-interaction is presented by a function E depending on the auxiliary fields. Two types of dualities inherent in the nonlinear electrodynamics models admit a simple off-shell characterization in terms of this function. In the standard formulation, the continuous U(1) duality symmetry is nonlinearly realized on the Maxwell field strength. In the new setting, the same symmetry acts as linear U(1) transformations of the auxiliary field variables. The nonlinear U(1) duality condition proves to be equivalent to the linear U(1) invariance of the self-interaction E. The discrete self-duality (or self-duality by Legendre transformation) amounts to a weaker reflection symmetry of E. For a class of duality- symmetric Lagrangians we introduce an alternative representation with the auxiliary scalar field and find new explicit examples of such systems.

description: We compute the first order chiral phase transition for an instanton motivated quark model with a local six-quark interaction. In order to compare different solutions of the gap equation we compute the bosonic effective action -- a two particle irreducible free energy functional. We find that the first order transition ends for a critical current quark mass, with continuous crossover for larger quark masses. Furthermore, we investigate different possible order parameters, including a color octet condensate. We also compare our formalism with mean field theory.

description: Deregulation can create new opportunities for rural America, but it may also introduce new costs. Rural areas are susceptible to changes in the industry that increase electricity costs because such areas are already expensive to serve, and the cooperatives that serve them tend to be small. This article discusses four electricity deregulation issues of importance to rural areas: transmission pricing and investment, retail competition, market power and mergers, and distributed generation.

description: Combination of different nontrivial topological states in a single material is capable of realizing multiple functionalities and exotic physics, but such materials are still very sparse. We report herein the results of magnetotransport measurements and ab initio calculations on single crystalline CaAl2Si2 semimetal. The transport properties could be well understood in connection with the two-band model, agreeing well with the theoretical calculations indicating four main sheets of Fermi surface consisting of three hole pockets centered at the Γ point and one electron pocket centered at the M point in the Brillouin zone. The single fundamental frequency imposed in the quantum oscillations of magnetoresistance corresponds to the electron Fermi pocket. Without spin-orbit coupling (SOC), the ab initio calculations suggest CaAl2Si2 as a system hosting a topological nodal-line setting around the Γ point in the Brillouin zone close to the Fermi level. Once including the SOC, the fragile nodal-line will be gapped and a pair of Dirac points emerge along the high symmetric Γ-A direction, which is about 1.22 eV below the Fermi level. The SOC can also induce a topological insulator state along the Γ-A direction with a gap of about 3 meV. The results demonstrate CaAl2Si2 as an excellent platform for the study of novel topological physics with multiple topological states.

In contrast to the power law inflation in standard model, we find that the inflationary phase can exit spontaneously without any mechanism. The running of the index of scalar perturbation spectrum can take an enough large value to match the observation data, while other parameters are in a reasonable region.

SDMX and the DDI: Using the Right Tool for the Job
Creators: name: Arofan Gregory
Publisher: name: Zenodo
Year: 2008

description: This paper covers the major features of the SDMX standard, and positions it relative to DDI versions 1.*/2.* and 3.0. It describes the typical use cases for each of the standards, and how to make an informed decision about which one best fits your needs. The two standards are complimentary, and the way in which they can be usefully employed in a single system is also addressed. There is an obvious overlap when dealing with multi-dimensional data, but there are many other points of alignment between the standards, and these are presented. Although DDI 3.0 was designed to be used in registry applications, it contains no specification of a standard registry, which SDMX does. The integration of DDI metadata into a standard SDMX registry implementation is described, to support collection, dissemination, data sourcing, and question, concept, and variable banks. Available tools and their integration are also discussed.

description: China is placing a high priority on urbanizing and raising the incomes of its huge rural population. The government is pursuing a strategy that seeks to channel rural people into small cities and towns rather than large cities. This strategy faces challenges in creating jobs for new residents and financing new town construction. Farms and businesses in rural America may increasingly compete and do business with their counterparts in rural China as trade between the two countries increases.

description: Immigration is changing the face of rural America, and employment in the food processing industry is a major draw to the rural Midwest. This article compares perceptions of economic strain, community concerns, community services, and nutritional well-being between long-term community residents and Hispanic immigrants in three rural Nebraska meatpacking communities. Several patterns emerged. Long-term residents reporting greater personal economic strain also reported poorer nutrition and those reporting more concern with community issues (e.g., language barriers) also reported greater difficulty obtaining community services (e.g., food assistance, affordable housing). Immigrants reporting greater economic strain also reported more concern with community issues and poorer nutrition.

description: In a Partially Aligned Two Higgs Doublet Model, where only is allowed flavor violation between third and second generation of fermions, we propose a mechanism to generate the second Yukawa matrix through a Unitary V-Spin flavor transformation on the mass matrix for quarks and leptons. Also we assume that this flavor transformation is universal, this is, we use the same parameters to generate Yukawa matrix elements in both sectors, reducing drastically the number of free parameters. As consequence we obtained a serie of relations between Yukawa matrix elements, that we called the Universality Constraint. Also, we obtained an interval of values for the second Yukawa matrix elements, expressed in terms of the Cheng and Sher ansatz, for $τ\to\ muμ^+μ^-$ and $τ\toγμ$ coming from the Universality Constraint and experimental bounds for light scalar masses. Finally, we show the allowed region of parameters for the flavor transformation from $B_s\toμμ$ decays, $B_s^0-\bar{B}_s^0$ mixing, $τ\toμμ^+μ^-$ and $τ\toγμ$ experimental bounds.

description: Studies about how to convey a message through a communication campaign abound, but another important aspect is what to communicate, in other words, selecting the information content of the campaign. In many situations where the degree of knowledge is directly related to consumption of a food product, choosing what to communicate is crucial. The present study proposes a model to decide what the consumer needs to know in order to take the decision to consume. The model is based on a Qualitative Comparative Analysis method with some subsequent conversions. It was applied to a real situation: selecting the information content of a communication campaign to boost the consumption of virgin olive oils in the Spanish market. The main findings suggest that campaigns should inform about virgin olive oils are the highest quality and most healthy, that there is a basic difference between olive oil and virgin olive oil in that olive oil is a mixture of virgin and refined olive oils, and that they are both equally fattening.
Practical Metadata Lessons: Utilising Metadata Standards for Archiving Data at Statistics New Zealand

description: At Statistics New Zealand we have been developing a data archiving solution in preparation for an organisation wide strategy (The "Business Model Transformation Strategy" (BmTS)) which will redesign processes, systems and tools for managing and storing data and metadata. The data archiving solution has been developed to apply to our current data stores and to archive surveys which will not transition as part of the BmTS. To fulfil the needs of the metadata component of the archiving solution we have used two standards: the Data Documentation Initiative (DDI) and the Preservation Metadata Implementation Strategies (PREMIS). The implementation of these standards has proven both a challenge and a learning experience. This presentation will cover some of the lessons we have learnt when implementing the two standards, as separate entities and in conjunction with each other, along with some of the benefits that have come from utilizing such open and established standards.
Of cloud and land

description: As an uncertain future looms, it is vital to explore the relationship between the city and the power structures and technologies that shape it. Today’s new empires of technology emerge to remake the city for their gain. They adopt narratives of sustainability, resilience, and a utopian belief in the possibility of improving life through technology. Through this lens, the city becomes a programmable space, reduced to 'solutionist' terms, where the messiness of urban life can be understood and logically optimized with enough data. While this claims to be in favor of innovation and improvement, these developments often benefit from and further enable existing power structures. They obscure environmental and social impacts through tools of sleek aesthetics and words like ‘the cloud’. In reality, cities built by the cloud are shaped by a controlled, exclusionary logic. They are designed around enclosure, centralization, monopolization, and the commodification of urban life for corporate gain. This project proposes moments of resistance that celebrate friction, complexity, and community at Amazon’s corporate headquarters in Seattle.

description: We consider the persistence probability, the occupation-time distribution and the distribution of the number of zero crossings for discrete or (equivalently) discretely sampled Gaussian Stationary Processes (GSPs) of zero mean. We first consider the Ornstein-Uhlenbeck process, finding expressions for the mean and variance of the number of crossings and the `partial survival' probability. We then elaborate on the correlator expansion developed in an earlier paper [G. C. M. A. Ehrhardt and A. J. Bray, Phys. Rev. Lett. 88, 070602 (2001)] to calculate discretely sampled persistence exponents of GSPs of known correlator by means of a series expansion in the correlator. We apply this method to the processes d^n x/dt^n=η(t) with n > 2, incorporating an extrapolation of the series to the limit of continuous sampling. We extend the correlator method to calculate the occupation-time and crossing-number distributions, as well as their partial-survival distributions and the means and variances of the occupation time and number of crossings. We apply these general methods to the d^n x/dt^n=η(t) processes for n=1 (random walk), n=2 (random acceleration) and larger n, and to diffusion from random initial conditions in 1-3 dimensions. The results for discrete sampling are extrapolated to the continuum limit where possible.

description: This study carries out hedonic price analysis of goat’s characteristics in five major markets of Pakistan. Data were collected about the various characteristics of each traded animal during the year 2016 through a structured questionnaire by using a personal interview method. A log-linear model was fitted to a sample of 500 observations in order to examine the determinants of observed goat prices. The results of the study showed that live weight, age, and sex were goat characteristics preferred by buyers and had significant positive effects on the prices of goats. Further, significant premiums were associated with the purpose of buying and marketplace. This study indicates that goat producers can improve their profitability when they target goat sales based on weight, marketing place, age, sex and time of sale, especially at the Muslim festival, Eid-ul-Azha.

description: The repercussions of reforming an agricultural market are mainly observed at the most vulnerable segment of the value chain, namely, the producers. In the current commodity market created with trade through the Ethiopian Commodity Exchange (ECX), coffee is less traceable to its producers. Only cooperatives that sell certified coffee through the unions they belong to, are allowed to bypass the more commodified ECX market. This study aims to investigate if small-scale coffee producers in southwestern Ethiopia that sell coffee through the certified cooperative are better off. It is assumed that the coffee sales through, and membership of, a cooperative, allows farmers to improve their coffee production as well as to improve other aspects of their livelihood. A sustainable livelihood approach was used as the inspiration for the welfare indicators that needed to be considered, data collected amongst members and non-members of certified cooperatives, and a propensity score model to investigate the impact of cooperative membership on the livelihood indicators. Results suggest that members of certified cooperatives indeed receive, on average, better prices. Yet, no evidence was found that indicates that the higher price is translated into better household income. Furthermore, coffee plantation productivity of those members who were interviewed was lower than that of the non-members. This finding could explain the failure to find an overall effect. Since the majority of the producers’ income emanate from coffee, a sustainable way of enhancing the productivity of the coffee could revitalize the welfare of the coffee producers.

description: Prompt optical emission of gamma-ray bursts (GRBs) is known to have important effects on the surrounding environment. In this paper, we study rotational disruption and alignment of dust grains by radiative torques (RATs) induced by GRB afterglows and predict their signatures on the observational properties of GRB afterglows. We first study grain disruption using RAdiative Torque Disruption (RATD) mechanism and find that large grains (size $>0.1 μ\rm m$) within a distance of $d< 40$ pc from the source can be disrupted into smaller grains. We then model the extinction curve of GRB afterglows and find that optical-NIR extinction is rapidly decreased, and UV extinction increases due to the conversion of large grains into smaller ones via RATD. The total-to-selective visual extinction ratio is found to decrease from the standard value of $R_{V}\sim 3.1$ to $\sim 1.5$ after disruption time $t_{\rm disr} \lesssim 10^{4}$ s. Next, we study grain alignment by RATs induced by GRB afterglows and model the wavelength-dependence polarization produced by grains aligned with magnetic fields. We find that polarization degree first increases due to enhanced alignment of small grains and then decreases when grain disruption by RATD begins. The maximum polarization wavelength $ λ_{\rm max}$ decreases rapidly from the standard value of $\sim 0.55 μ\rm m$ to $\sim 0.15 μ\rm m$ over alignment time of $t_{\rm align} \lesssim 30$ s due to enhanced alignment of small grains. Finally, we found that RATD induces a significant decrease in optical/NIR extinction, producing an optical re-brightening in the observed light curve of GRB afterglows. We show that our theoretical predictions can explain various observational properties of GRB afterglows, including steep extinction curves, time-variability of colors, and optical re-brightening of GRB afterglows.

description: Using Amartya Sen’s capability approach and household survey data from Inner Mongolia, China, this paper constructs a welfare index in order to examine the impact of crop insurance on the welfare of farmers. Fuzzy comprehensive evaluation methods were used to measure changes in farmers’ welfare before and after participating in crop insurance, and these were empirically tested to identify differences in the factors affecting farmers’ welfare. It was found that after participating in crop insurance, the overall welfare level of farmers slightly increased. Many functional indicators improved, such as family economic status, working status, protective security, and psychological experience; however, the living environment and leisure time of farmers deteriorated after participation. From the perspective of conversion factors, variables such as the educational level of the head of household, the total number of members in a given household, the policy of crop insurance and regional economic development level all have a significant impact on the changes in farmers’ welfare.

description: Using case studies of the bamboo and cinnamon value chains in rural areas of northern Vietnam, this paper contributes to the existing literature by analyzing barriers and suggests conditions under which value chain lending would be an effective tool for improving smallholder farmers’ access to credit. A mixed method using both in-depth interviews with relevant stakeholders and a two-stage Heckman model is employed to explain the existing credit gap. Findings show that in both chains, bank decision-making on lending is typically limited to individual chain actors instead of considering the whole chain. Commercial banks predominately use conventional lending approaches heavily dependent on collateral which typically results in a shortage of credit available to the chain actors. Value chain lending is constrained by weak chain linkages and limited ownership of private bank accounts. Drawing from these cases in Vietnam, the article concludes by arguing that status quo value chain lending in lower-income countries merits considerable rethinking. The lending approaches of banks require innovation to ‘think beyond collateral’ in improving chain cohesion. Multistakeholder partnerships are important for successful value chain lending. In addition, farmer-based unions have the potential to address issues of information asymmetry in the credit market.
Supersymmetric Intersections of M-branes and pp-waves

description: We study supersymmetric intersections of M2 and M5 branes with different pp-waves of M-theory. We consider first M-brane probes in the background of pp-waves and determine under which conditions the embedding is supersymmetric. We particularize our formalism to the case of pp-waves with 32, 24 and 20 supersymmetries. We also construct supergravity solutions for the brane-wave system. Generically these solutions are delocalised along some directions transverse to the brane and preserve the same number of supersymmetries as in the brane probe approach.

description: The prevailing description for dissipative quantum dynamics is given by the Lindblad form of a Markovian master equation, used under the assumption that memory effects are negligible. However, in certain physical situations, the master equation is essentially of a non-Markovian nature. This paper examines master equations that possess a memory kernel, leading to a replacement of white noise by colored noise. The conditions under which this leads to a completely positive, trace-preserving map are discussed for an exponential memory kernel. A physical model that possesses such an exponential memory kernel is presented. This model contains a classical, fluctuating environment based on random telegraph signal stochastic variables.

description: The efficiency of working capital is a major determinant of firm profitability. So, the grasp of working capital dynamics is extremely important for managers, but also for policy makers, since inefficient working capital management is an important source of industrial sickness. This study focuses on the profitability impacts of working capital policies of Turkish agribusinesses, and aims to investigate the potential effects of globalization on these interrelated relationships. The findings obtained from pooled panel analyses demonstrate that Turkish agribusinesses can enhance their profitability and value by adopting a conservative working capital policy through lengthening the cash conversion cycle up to an optimal level. Besides, globalization is found to deteriorate their efficiency and profitability where economic globalization seems to have the highest impact raising questions on the effectiveness of Turkish agribusinesses in coping with competition. Thus, both the managers and the policy makers should concern with the competitiveness impacts of globalization.

description: We report the first observation of the charmless hyperonic B decay, B^+ --> Lambda Lambdabar K^+, using a 140 fb^-1 data sample recorded at the Upsilon(4S) resonance with the Belle detector at the KEKB e^+e^- collider. The measured branching fraction is B(B^+ --> Lambda Lambdabar K^+) = 2.91 ^{+0.90}_{-0.70} +/- 0.38 *10^-6 . We also perform a search for the related decay mode B^+ --> Lambda Lambdabar pi^+, but do not find a significant signal. We set a 90% confidence-level upper limit of B(B^+ --> Lambda Lambdabar pi^+) < 2.8 * 10^-6.

description: Single shot x-ray diffraction (XRD) experiments have been performed with a x-ray free electron laser (XFEL) under pulsed high magnetic fields up to 16 T generated with a nondestructive minicoil. The antiferromagnetic insulator phase in a perovskite manganaite, Pr$_{0.6}$Ca$_{0.4}$MnO$_{3}$, is collapsed at a magnetic field of $\approx 8$ T with an emergence of the ferromagnetic metallic phase, which is observed via the accompanying lattice changes in a series of the single shot XRD. The feasibility of the single shot XRD experiment under ultrahigh magnetic fields beyond 100 T is discussed, which is generated with a portable destructive pulse magnet.
