description: The article proposes a critical perspective on the potential impact of the growing cryptocurrency ecosystem on the process of democratizing money. After examining the various interpretations of the term “democratization”, we focus on one interpretation: that of financial inclusion. We propose a categorization of currently available cryptocurrencies, distinguishing four macro-categories: Bitcoin; altcoins, which include all alternative and/or complementary cryptocurrencies to Bitcoin; stablecoins, which are digital coins whose value is pegged to a fiat currency; and central bank digital currencies (CBDCs). We provide a description of the economic characteristics of each category and analyse how and whether these instruments can contribute to financial inclusion. While each category appears to be capable of contributing to the democratization of money, CBDCs are the only ones that can truly pursue the goal of financial inclusion. Therefore, we argue that it is not money as such that needs to be democratized, but rather the role that central banks play in the economic system.

description: We map the kinematics of stars in simulated galaxy disks with spiral arms using the velocity ellipsoid vertex deviation (l$_v$). We use test particle simulations, and for the first time, fully self-consistent high resolution N-body models. We compare our maps with the Tight Winding Approximation model analytical predictions. We see that for all barred models spiral arms rotate closely to a rigid body manner and the vertex deviation values correlate with the density peaks position bounded by overdense and underdense regions. In such cases, vertex deviation sign changes from negative to positive when crossing the spiral arms in the direction of disk rotation, in regions where the spiral arms are in between corotation (CR) and the Outer Lindblad Resonance (OLR). By contrast, when the arm sections are inside the CR and outside the OLR, l$_v$ changes from negative to positive.We propose that measurements of the vertex deviations pattern can be used to trace the position of the main resonances of the spiral arms. We propose that this technique might exploit future data from Gaia and APOGEE surveys. For unbarred N-body simulations with spiral arms corotating with disk material at all radii, our analysis suggests that no clear correlation exists between l$_v$ and density structures.

description: The internet is increasingly becoming a standard for both the production and consumption of data while at the same time cyber-crime involving the theft of private data is growing. Therefore in efforts to securely transact in data, privacy and security concerns must be taken into account to ensure that the confidentiality of individuals and entities involved is not compromised, and that the data published is compliant to privacy laws. In this paper, we take a look at noise addition as one of the data privacy providing techniques. Our endeavor in this overview is to give a foundational perspective on noise addition data privacy techniques, provide statistical consideration for noise addition techniques and look at the current state of the art in the field, while outlining future areas of research.

description: This paper develops a panel data econometric analysis in order to determine the main macroeconomic causes of household indebtedness in the European Union countries from 1995 to 2019. During that time, household indebtedness reached unprecedented and unsustainable levels, which played a crucial role in the emergence of the last financial and economic crisis. This is not clearly well interpreted by the mainstream economics, which advocates that household indebtedness is just an instrument to smooth consumption in a continuous process of utility maximization over life. This paper estimates a model according to which the household indebtedness depends on seven mainstream and non-mainstream macroeconomic causes, namely housing prices, financial asset prices, personal income inequality, the households’ labour income, welfare state expenditures, the working-age population and interest rates. This paper finds that housing prices, welfare state expenditures and interest rates impact positively on household indebtedness in the European Union countries, whilst the financial asset prices, personal income inequality and households’ labour income impact negatively on household indebtedness in the European Union countries. This paper also finds that the fall of household labour income and the rise of the housing prices have been the main triggers of household indebtedness in the European Union countries since 1995.

description: TikTok has been criticized for its low privacy standards, but little is known about how its adolescent users protect their privacy. Based on interviews with 54 adolescents in Switzerland, this study provides a comprehensive understanding of young TikTok users' privacy management practices related to the creation of videos. The data were explored using the COM-B model, an established behavioral analysis framework adapted for sociotechnical privacy research. Our overall findings are in line with previous research on other social networks: adolescents are aware of privacy related to their online social connections (social privacy) and perform conscious privacy management. However, we also identified new patterns related to the central role of algorithmic recommendations potentially relevant for other social networks. Adolescents are aware that TikTok's special algorithm, combined with the app's high prevalence among their peers, could easily put them in the spotlight. Some adolescents also reduce TikTok, which was originally conceived as a social network, to its extensive audio-visual capabilities and share TikToks via more private channels (e.g., Snapchat) to manage audiences and avoid identification by peers. Young users also find other creative ways to protect their privacy such as identifying stalkers or maintaining multiple user accounts with different privacy settings to establish granular audience management. Based on our findings, we propose various concrete measures to develop interventions that protect the privacy of adolescents on TikTok.

description: The ritterazine and cephalostatin natural products have biological activities and structures that are interesting to synthetic organic chemists. These products have been found to exhibit significant cytotoxicity against P388 murine leukemia cells, and therefore have the potential to be used as anticancer drugs. The ritterazines and cephalostatins are steroidal dimers joined by a central pyrazine ring. Given that the steroid halves are unsymmetrical and highly oxygenated, there are several challenges in synthesizing these compounds in an organic laboratory.

Ritterazine B is the most potent derivative in the ritterazine family. Its biological activity is comparable to drugs that are being used to treat cancer today. For this reason, and the fact that there are no reported syntheses of ritterazine B to date, our lab set out to synthesize this natural product.

Herein, efforts toward the synthesis of the western fragment of ritterazine B are described. Two different routes are explored to access a common intermediate. An alkyne conjugate addition reaction was initially investigated due to the success of this key reaction in the synthesis of the eastern fragment. However, it has been found that a propargylation reaction has greater reactivity and yields, and has the potential to reduce the step count of the synthesis of the western fragment of ritterazine B.

description: We have considered the complexity and asymptotic stability in the process of biochemical substance exchange in a coupled ring of cells. We have used coupled maps to model this process. It includes the coupling parameter, cell affinity and environmental factor as master parameters of the model. We have introduced: (i) the Kolmogorov complexity spectrum and (ii) the Kolmogorov complexity spectrum highest value to analyze the dynamics of two cell model. The asymptotic stability of this dynamical system using an eigenvalue-based method has been considered. Using these complexity measures we have noticed an 'island' of low complexity in the space of the master parameters for the weak coupling. We have explored how stability of the equilibrium of the biochemical substance exchange in a multi-cell system (N=100) is influenced by the changes in the master parameters of the model for the weak and strong coupling. We have found that in highly chaotic conditions there exists space of master parameters for which the process of biochemical substance exchange in a coupled ring of cells is stable.

Democracy and Equality in Latin America: Elite-captured systems and Multidimensional Inequalities
Creators: name: Davalos Arias, German Ignacio
Publisher: name: University of Chicago
Year: 2023

description: Despite the intuitive theoretical relationship suggested by the standard (Meltzer & Richard, 1981) model, the empirical results of the vast literature studying the effects of democracy on redistribution and inequality are many times ambiguous and don’t point towards a clear consensus. Acemoglu et al. (2015) developed a unified framework to capture the more nuanced relationship between these variables, and to incorporate some of the theoretical mechanisms proposed by the literature to explain its ambiguous results. This paper follows this framework, first validating its results on a reduced sample (Latin American countries) and extended data; and then expands on it by first considering a broader conception of inequality —based on Sen’s (1999) capabilities approach— and then by exploring the role that “elite-captured” political systems —operationalized following Albertus & Menaldo (2018)— may play in explaining the sometimes-contradictory empirical relationship between democracy and inequality. The results from this exploratory quantitative analysis provide support to the hypotheses of both extensions being potentially relevant for a complete analysis of democracy and inequality in the Latin American region, and the most robust findings suggest that elite-power in Latin America mitigates the inequality-decreasing effects of democratization.

description: Among various methods to learn a second language (L2), such as listening and shadowing, Extensive Viewing involves learning L2 by watching many videos. However, it is difficult for many L2 learners to smoothly and effortlessly comprehend video contents made for native speakers at the original speed. Therefore, we developed a language learning assistance system that automatically adjusts the playback speed according to the learner's comprehension. Our system judges that learners understand the contents if they laugh at the punchlines of comedy dramas, and vice versa. Experimental results show that this system supports learners with relatively low L2 ability (under 700 in TOEIC Score in the experimental condition) to understand video contents. Our system can widen learners' possible options of native speakers' videos as Extensive Viewing material.

description: The present work investigates the links between Ricardian and Sraffian economic analyses and the emerging themes of ecological macroeconomics, namely the impact of global warming and ecological or natural crises, the depletion of non-produced material resources, and the energy transition. The objectives of the work are: (a) to introduce the foundations of ecological economics through a simple representation of Ricardo’s economic theory of the falling rate of profit (i.e., the stationary state), explaining the socio-economic impact of ecological crises linked to production process (global warming, land pollution, flooding, etc.) and of the shrinkages in the supply (extraction) of non-produced factors like energy materials (oil, coal, liquefied natural gas, etc.); (b) to evaluate the institutional conditions that must be met to make the energy transition from fossil fuels to renewable resources economically meaningful when capital accumulation is the main driver of economic growth; and (c) to broaden the field of research and perspectives within heterodox approaches to ecological macroeconomics by introducing new foundations based on modern Classical political economy.

We show theoretical estimates for the standard polarization parameters for different frames usually adopted in the literature, in the large $P_T$ region, namely $P_T\gg Λ_\text{QCD}$, where collinear factorization is expected to hold. We adopt both the Color Singlet Model and the Nonrelativistic QCD approach, paying special attention to the role of different sets of Long Distance Matrix Elements. Finally we present a preliminary analysis of some frame independent polarization invariants.

description: In $\mathrm{U(1)}$ lattice gauge theory in three spacetime dimensions, confinement can be analytically shown to persist at all values of the coupling. Furthermore, the explicit predictions for the dependence of string tension $σ$ and mass gap $m_0$ on the coupling allow one to tune their ratio at will. These features, and the possibility of obtaining high-precision numerical results via an exact duality map to a spin model, make this theory an ideal laboratory to test the effective string description of confining flux tubes. In this contribution, we discuss our investigation of next-to-leading-order corrections to the confining potential and of the finite-temperature behavior of the flux tube width. Our data provide a very stringent test of the theoretical predictions for these quantities and allow to test their dependence on the $m_0/\sqrtσ$ ratio.

We prove that there is an elliptic curve $C\subset X$ such that the generic rank over $k$ of $X$ after a base extension by $C$ is strictly larger than the generic rank of $X$. Moreover, if the generic rank of $π_j$ is positive then there are infinitely many fibers of $π_i$ ($j\neq i$) with rank at least the generic rank of $π_i$ plus one.

description: The purpose of this study is to assess, from a Balance of Payment Constraint Growth (BPCG) theoretical perspective, current key challenges of developing countries that spring from two broad exogenous factors. These factors are: i) global shocks that affect the world economy, and ii) major economic policy changes in developed countries. The BPCG perspective helps to identify to what extent these challenges are rooted in the developing countries’ vulnerabilities and structural weaknesses linked to their role in international trade and capital markets. To discuss the current uncertain global environment potential implications for developing economies – growing inflation, hawkish monetary policy, cross-border flows redistribution, as well as the geopolitical redefinition of international trade and global value chains, among others - the present work builds a BPCG model for the post-COVID era and applies it to evaluate challenges to growth in six countries: Chile, Colombia, Ghana, India, Mexico, and Turkey.

description: With the advent of virtualization and artificial intelligence, research on networked systems has progressed substantially. As the technology progresses, we expect a boom in not only the systems research but also in the network of systems domain. It is paramount that we understand and develop methodologies to connect and communicate among the plethora of devices and systems that exist today. One such area is mobile ad-hoc and space communication, which further complicates the task of networking due to myriad of environmental and physical conditions. Developing and testing such systems is an important step considering the large investment required to build such gigantic communication arrangements. We address two important aspects of network emulation in this work. We propose a network emulation framework, which emulates the functioning of a hierarchical software defined network. One such use-case is described using a mobile ad-hoc network (MANET) topology within a single system by leveraging contemporary network virtualization technologies. We present various aspects of the network, such as the dynamic communication in the software domain and provide a novel approach to build upon existing emulation techniques. The second part of the thesis presents a dynamic network link emulator. This emulator enables suitable link property re-configurations such as bandwidth, delay and packet loss for networked systems using simulation software. We characterize the results of tests for the link emulation using a hardware and software testbed. Through this thesis, we aim to make a small yet crucial contribution to the niche area of software defined networks.

description: In this paper, we consider how to formulate semiclassical problems in the context of the AdS/CFT correspondence, based on the proposal of Compere and Marolf. Our prescription involves the effective action with self-action term for boundary dynamical fields, which can be viewed as imposing mixed boundary conditions for the gravity dual. We derive the semiclassical Einstein equations sourced by boundary CFT stress-energy tensor. Analyzing perturbations of the holographic semiclassical Einstein equations, we find a universal parameter $γ_d$ which controls the contribution from boundary CFTs and specifies dynamics on the AdS boundary. As a simple example, we examine the semiclassical Einstein equations in $3$-dimensions with $4$-dimensional AdS gravity dual, and show that the boundary BTZ black hole with vanishing expectation value of the stress-energy tensor becomes unstable due to the backreaction from quantum stress-energy tensor when the parameter $γ_d$ exceeds a certain critical value.

With this, I confirm a conjecture from simulations that the velocity autocorrelation function decays algebraically, ψ(t) ~ t^{-3/2}, if momentum is conserved. I show that the slow decay is due to the coupling to transverse currents.

description: Slides of the presentation given at the 2022 LIS Bibliometrics Conference (day 2) held on October 12th 2022. The main theme of the conference was "Measuring What Matters". Abstract  The Impact Factor (IF) has been the subject of much criticism and controversy, particularly in the current state of advocacy for more responsible metrics and reforms of research assessment. Much of this criticism focuses on how and why the metric itself is flawed, i.e. how it favors citation-dense fields, how it presents skewed citation distribution in using average data, and how it does not correlate with quality of research, nor its reliability. Little attention, however, has been paid to how and why the IF brand may jeopardize bibliodiversity in the scholarly publishing landscape, i.e. diversity as it can relate to journal-level variables such as publishing model, world regions and language(s) of publication, subject categories, publisher, and APC prices (if any). Measuring these variables and assessing in what ways they may reflect a lack of bibliodiversity is of crucial importance if we want to promote an equitable and sustainable scholarly publishing landscape and research assessment culture. This lightning talk will present highlights of this counting-back strategy, which we applied to IF journals included in the 2021 Journal Citations Report. Our results indicate that the IF brand shows little diversity in terms of languages and country of publications, reinforces the oligopoly of academic publishing, and produces disincentives for fair and equitable Open Access by favoring hybrid journals and high APC prices. On the whole, this lack of bibliodiversity is very much sustained by big commercial publishers and the Global North. We suggest that this state of bibliodiversity of the IF brand should also be taken into account in future endeavors of research assessment reforms, which cannot happen without a reflection on the decolonization of scholarly publishing.

title: Metric Learning via Linear Embeddings for Human Motion Recognition
Creators: name: Kong, ByoungDoo
Publisher: name: University of Massachusetts Amherst
Year: 2020

description: We consider the application of Few-Shot Learning (FSL) and dimensionality reduction to the problem of human motion recognition (HMR). The structure of human motion has unique characteristics such as its dynamic and high-dimensional nature. Recent research on human motion recognition uses deep neural networks with multiple layers. Most importantly, large datasets will need to be collected to use such networks to analyze human motion. This process is both time-consuming and expensive since a large motion capture database must be collected and labeled. Despite significant progress having been made in human motion recognition, state-of-the-art algorithms still misclassify actions because of characteristics such as the difficulty in obtaining large-scale leveled human motion datasets. To address these limitations, we use metric-based FSL methods that use small-size data in conjunction with dimensionality reduction. We also propose a modified dimensionality reduction scheme based on the preservation of secants tailored to arbitrary useful distances, such as the geodesic distance learned by ISOMAP. We provide multiple experimental results that demonstrate improvements in human motion classification.
Nonlocal Kondo effect and two-fluid picture revealed in an exactly solvable model

description: Understanding the nature of local-itinerant transition of strongly correlated electrons is one of the central problems in condensed matter physics. Heavy fermion systems describe the f-electron delocalization through Kondo interactions with conduction electrons. Tremendous efforts have been devoted to the so-called Kondo-destruction scenario, which predicts a dramatic local-to-itinerant quantum phase transition of f-electrons at zero temperature. On the other hand, two-fluid behaviors have been observed in many materials, suggesting coexistence of local and itinerant f-electrons over a broad temperature range but lacking a microscopic theoretical description. To elucidate this fundamental issue, here we propose an exactly solvable Kondo-Heisenberg model in which the spins are defined in the momentum space and the k-space Kondo interaction corresponds to a highly nonlocal spin scattering in the coordinate space. Its solution reveals a continuous evolution of the Fermi surfaces with Kondo interaction and two-fluid behaviors similar to those observed in real materials. The electron density violates the usual Luttinger's theorem, but follows a generalized one allowing for partially enlarged Fermi surfaces due to partial Kondo screening in the momentum space. Our results highlight the consequence of nonlocal Kondo interaction relevant for strong quantum fluctuation regions, and provide important insight into the microscopic description of two-fluid phenomenology in heavy fermion systems.

description: Football is a sport that involves a combination of continuous and intermittent effort. Therefore, players need to be able to recover quickly between moments of high intensity to continue to perform at a high level of output throughout the entire match. The present study aimed to evaluate the effect of an intermittent exercise protocol on the rate of high-intensive force production through the countermovement test (CMJ) in elite Portuguese female soccer players. The sample consisted of 12 players from the first division of women's football in Portugal (Age = 18.1 ± 0.9 years; Weight = 60.10 ± 5.8 Kg; Height = 1.63 ± 4.8 cm; BMI = 22.48 ± 1.5 kg/m2). The players performed an intermittent exercise protocol on a cycle ergometer, lasting 8 minutes, in which each minute corresponded to 40 seconds of high-intensity (4W/kg, based on the player's body weight) and 20 seconds of low-intensity (75W). Before and after the protocol, the players performed the CMJ. Through the results obtained, it was possible to observe that players presented a significant decrease in the height of the CMJ between the two moments (before- 29.92 ± 3.55cm vs after- 26.92 ± 4.05cm; p < 0.01). The present study allowed us to conclude that intermittent exercise protocol promoted a negative influence on CMJ performance.

description: Bounded confidence opinion dynamics model the propagation of information in social networks. However in the existing literature, opinions are only viewed as abstract quantities without semantics rather than as part of a decision-making system. In this work, opinion dynamics are examined when agents are Bayesian decision makers that perform hypothesis testing or signal detection, and the dynamics are applied to prior probabilities of hypotheses. Bounded confidence is defined on prior probabilities through Bayes risk error divergence, the appropriate measure between priors in hypothesis testing. This definition contrasts with the measure used between opinions in standard models: absolute error. It is shown that the rapid convergence of prior probabilities to a small number of limiting values is similar to that seen in the standard Krause-Hegselmann model. The most interesting finding in this work is that the number of these limiting values and the time to convergence changes with the signal-to-noise ratio in the detection task. The number of final values or clusters is maximal at intermediate signal-to-noise ratios, suggesting that the most contentious issues lead to the largest number of factions. It is at these same intermediate signal-to-noise ratios at which the degradation in detection performance of the aggregate vote of the decision makers is greatest in comparison to the Bayes optimal detection performance.

description: This paper presents a preliminary comparison of the Eurosystem response to the Global Financial Crisis and Eurozone Crises with the onset of the Coronavirus Pandemic in 2020. It analyzes bank, national central bank (NCB), and government balance sheets to show the effect of ECB decisions to consrain or enable liquidity provision across the Eurozone, particularly along core and peripheral lines. It argues that these dynamics reflect Post-Keynesian theories of endogenous money, and the potential for monetary authorities to structurally influence liquidity preference and provision. As Eurozone governments debate whether to continue these practices, systemic liquidity crises that hurt financial and fiscal activity remain a risk at the time of writing.

description: This article assesses the effects of real exchange rate misalignment on long-term growth, between 1995 and 2018, in a set of 151 countries. Our findings indicate that a competitive real exchange rate is positively associated with growth over the long run. The novel element here is our demonstration that the enhanced international competitiveness generated by lower labor costs may increase growth. The study also includes a series of robustness checks and alternative estimates to better understand this association, using seven different measures of real exchange rate misalignment, controlling for the possibility that the real exchange rate has a non-monotonic effect on growth, testing the Washington Consensus, separately estimating the effects of real exchange rate devaluation and overvaluation, testing the argument that a real exchange rate policy is an important factor in explaining why Asian economies perform better than Latin American and African ones, and employing alternative measures for real exchange rate misalignment.

description: The foundation for both the neo-Schumpeterian and original institutional economics school of thought is the emphasis on evolutionary processes in economies. The relationship between technology and the social rules and norms that coordinate the behavior of people provides the focus for their respective conceptualizations of such processes. However, the seemingly familial relation of their analytical frameworks is tempered by how they conceptualize social rules and norms. We discuss the differences between neo-Schumpeterian and original institutional economics. These differences are a result of each approach’s conceptualizations of social rules and norms, in particular when it comes to evolutionary processes and innovation dynamics.

description: These Sessional Clippings books cover the period 1891 to 1972, and include newspaper accounts written by various legislative reporters who covered debates occurring in the British Columbia Legislative Assembly. Transcripts of debates of the Legislative Assembly (Hansard) were not published in B.C. until 1970; hence these "Sessional Clipping Books" augment the "Journals", the record of daily proceedings of the Legislative Assembly. Selected clippings from various newspapers including the Vancouver Sun, the Vancouver Province, the Colonist, and the Times newspapers, relating to the newspaper reports concerning activities of the Legislature. The original sessional clippings books comprise 351 ledger size print volumes, held at the Legislative Library in Victoria BC. The print volumes were microfilmed onto 26 reels in 1977 under a Tri University Libraries (TRIUL) project by Precision Micrographic Services (Vancouver, B.C.), with the permission of the Legislative Library, Victoria, British Columbia. This digital collection was created by scanning the 26 microfilm reels.
title: A Study on Latent Thermal Energy Storage (LTES) using Phase Change Materials (PCMs) 2020

description: The significant increase in energy requirements across the world, provides several opportunities for innovative methods to be developed to facilitate the storage and utilization of energy. The major energy demand is in the form of electrical energy for domestic as well as industrial sectors, a large part of which are the heating and cooling requirements. Appropriate utilization of thermal energy storage can effectively aid in reducing the electrical demand by storage and release of this thermal energy during peak hours.
Thermal Energy Storage using Phase Change Materials (PCMs) is an attractive method of energy storage, with a wide variety of potential applications. Several configurations have been tested by researchers to develop energy storage devices with PCMs. The cycling of melting and solidification of PCMs results in storage and release of heat at a relatively small temperature difference. Design and deployment of these storage systems have certain challenges and considerations associated to them for instance, when used in buildings, PCMs should be non-toxic, non-corrosive, and others.
In this thesis, we aim to provide models for designing Latent Thermal Energy Storage (LTES) devices with PCMs, based on their operating conditions, thermophysical properties of materials, and geometric parameters. The models are developed considering fluid dynamics and heat transfer involved in melting and solidification of PCMs. Parameters like inlet temperature and velocity, and volume of storage container are varied to determine the time taken for melting or solidification. For sizing and predicting performance of the storage devices we aim at presenting an analytical correlation, with time taken for melting as the variable defining the ‘charging/discharging time’ of storage device. Along with this, a transient model is developed to predict amount of PCM melted/solidified, along with rate of latent energy storage in defined time period intervals.
