description: In order to develop infocommunications devices so that the capabilities of the human brain may interact with the capabilities of any artificially cognitive system a deeper knowledge of aging is necessary. Especially if society does not want to exclude elder people and wants to develop automatic systems able to help and improve the quality of life of this group of population, healthy individuals as well as those with cognitive decline or other pathologies. This paper tries to establish the variations in handwriting tasks with the goal to obtain a better knowledge about aging. We present the correlation results between several parameters extracted from online handwriting and the age of the writers. It is based on BIOSECURID database, which consists of 400 people that provided several biometric traits, including online handwriting. The main idea is to identify those parameters that are more stable and those more age dependent. One challenging topic for disease diagnose is the differentiation between healthy and pathological aging. For this purpose, it is necessary to be aware of handwriting parameters that are, in general, not affected by aging and those who experiment changes, increase or decrease their values, because of it. This paper contributes to this research line analyzing a selected set of online handwriting parameters provided by a healthy group of population aged from 18 to 70 years. Preliminary results show that these parameters are not affected by aging and therefore, changes in their values can only be attributed to motor or cognitive disorders.

description: We study the impacts of reheating temperature on the inflationary predictions of the spectral index and tensor-to-scalar ratio. Assuming sinusoidal oscillations and that reheating process is very fast, the reheating temperature can be constrained for sinusoidal oscillation within a factor of 10 - 100 or even better with the prospect of future observations. Beyond this, we find that the predictions can also be insensitive to the reheating temperature in certain models, including Higgs inflation.

These amplitudes, when expressed in terms of the appropriate kinematic invariants, are independent of the masses and therefore identical to the corresponding massless amplitudes.

description: Based on the notion of entrepreneurship-as-emancipation, we develop a model of humanistic entrepreneurship intended to achieve social justice-related outcomes. Humanistic entrepreneurship is the process of discovering, assessing, and pursuing opportunities through social innovation to achieve just social change. We integrate theories of moral conviction and resource mobilization to propose that humanistic entrepreneurs are morally motivated agents who utilize entrepreneurship to stimulate collective action, mobilize resources, and change institutional environments. The goal of humanistic entrepreneurs is to protect human dignity and alleviate the suffering of people experiencing the consequences of social injustice. We apply the model of humanistic entrepreneurship to the historic case of Frances Wright, a social enterprise pioneer who challenged institutions of social injustice.

description: Many techniques have been used to measure the Young’s modulus of ice. The purpose of this bachelor thesis is to develop a more effective and precise technique. The impulse-echo method has been used to measure the longitudinal ultrasonic velocities of three different types of specimens. From this, the Young’s modulus has been calculated. The specimens included homogeneous, inhomogeneous and a cracked polycrystalline ice Ih sample. The homogenous samples studied were found to be elastic isotropic, whereas the inhomogeneous and cracked sample were found to have an anisotropic elastic behaviour. For the cracked specimen, different decreases of the Young’s moduli were measured in different directions. The results showed an overall scatter and gives therefore only temporary and rough values for the longitudinal sound velocity in a homogenous polycrystalline ice specimen. Further, the applied method is applicable to detect different types of ice with different composites and manufacturing, and to identify a change of elastic properties after crack.

description: Dans son ouvrage, Le capital au XXIe siècle, Thomas Piketty souligne les risques d’une explosion des inégalités de patrimoine, car le capital augmenterait plus vite que le revenu dans plusieurs pays, dont la France. Nous reviendrions ainsi au niveau des inégalités du début du XXe siècle. Dans cette note, nous montrons que cette conclusion n’est pas plausible. D’abord, elle repose sur la hausse d’une seule des composantes du capital : le capital logement. Le capital dit "productif", hors immobilier, n’a que légèrement augmenté dans les dernières décennies, et sur le long terme, n’est pas en hausse tendancielle. Ensuite, si la valeur du capital immobilier mesurée dans les comptabilités nationales a augmenté sur cette période, c’est en raison de la hausse des prix de l’immobilier, qui ont crû beaucoup plus vite que les loyers et que les revenus depuis 2000. Or, les prix de l’immobilier ne sont pas corrélés aux revenus du capital logement. Au contraire, ce sont les loyers qui importent pour la dynamique des inégalités puisqu’ils représentent à la fois les revenus du capital des propriétaires-bailleurs et les dépenses économisées des propriétaires-occupants. Pour qualiﬁer la hausse des inégalités de patrimoine, il faut donc mesurer le capital immobilier à partir des loyers - la valeur d’un logement est une somme de ses loyers actualisés - et non à partir des prix d’acquisition et de cession des biens immobiliers. Notre conclusion est alors que sur les dernières décennies, le ratio capital sur revenu, correctement évalué, est resté stable en France, en Grande-Bretagne, aux Etats-Unis et au Canada, ce qui contredit donc assez nettement la thèse de l’auteur. Cela ne signiﬁe pas que les prix de l’immobilier n’ont aucun impact sur les inégalités : la valeur des logements ayant augmenté, les propriétaires détiennent une réserve de valeur plus importante, mobilisable en cas de perte majeure de revenus ; il est par ailleurs devenu plus difﬁcile pour une personne sans capital de départ d’accéder à la propriété. Cependant, les revenus immobiliers des propriétaires ne se sont pas accrus pour autant, et il est donc difﬁcile de maintenir la thèse d’une dynamique divergente d’accumulation du capital à partir de ces tendances.

description: Using the network of university classmates among corporate directors and politicians and the regression discontinuity design of close gubernatorial elections from 1999 to 2010, we identify the positive and significant impact of social-network based political connections on firm value. Firms connected to elected governors increase value by 1.36% on average surrounding the election date. Political connections are more valuable in a state with a higher level of regulation and corruption, in smaller firms, and in firms dependent on external finance. Firms connected to election winners invest more, earn better operating performance, hold more cash, and enjoy better long-term stock performance.

description: GRB 190829A is the fourth closest gamma-ray burst (GRB) to date ($z=0.0785$). Owing to its wide range of radio, optical, X-ray, and the very-high-energy (VHE) observations by H.E.S.S., it has become an essential new source examined by various models with complementary approaches. We here show in GRB 190829A the double-prompt pulses and the three-multiwavelength afterglows are consistent with the type II binary-driven hypernova (BdHN II) model. The progenitor is a binary composed of a carbon-oxygen (CO) star and a neutron star (NS) companion. The gravitational collapse of the iron core of the CO star produces a supernova (SN) explosion and leaves behind a new neutron star ($ν$NS) at its center. The accretion of the SN ejecta onto the NS companion and onto the $ν$NS via matter fallback spins up the NSs and produces the double-peak prompt emission. The synchrotron emission from the expanding SN ejecta with the energy injection from the rapidly spinning $ν$NS and its subsequently spin-down leads to the afterglow in the radio, optical, and X-ray. We model the sequence of physical and related radiation processes in BdHNe and focus on individuating the binary properties that play the relevant roles.

description: We use the latest Type Ia supernovae sample Pantheon+ to explore new physics on cosmic scales. Specifically, in light of this new sample, we constrain the interacting dark energy and Hu-Sawicki $f(R)$ gravity models and employ the model-independent Gaussian processes to investigate whether there is an evidence of dark energy evolution. We find that Pantheon+ alone just gives weak constraints. However, a data combination of Pantheon+ with cosmic microwave background, baryon acoustic oscillations and cosmic chronometers gives a strong constraint on the modified matter expansion rate $ε=0.048\pm0.026$, which indicates that the momentum may transfer from dark energy to dark matter in the dark sector of the universe at the $1.85\,σ$ confidence level. In the meantime, we obtain a very tight constraint on the deviation from general relativity $\log_{10} f_{R0}< -6.32$ at the $2\,σ$ confidence level. Interestingly, when combining Pantheon+ with cosmic chronometers and cosmic microwave background data, we find a quintessence-like dark energy signal beyond the $2\,σ$ confidence level in the redshift range $z\in[0.70,1.05]$. This implies the nature of dark energy may actually be dynamical.

description: We investigate the relationship between inter-jurisdictional cooperation and law enforcement in Mexico. Exploiting a Regression Discontinuity Design in close municipal elections, we study how improved opportunities for cooperation in crime prevention among neighboring municipalities - proxied by their degree of political alignment - may result in lower rates of violent crime. We find that municipalities in which the party in power in the majority of neighboring jurisdictions barely won experience significantly lower homicide rates during the mayor’s mandate than those in which it barely lost. This effect is sizeable and independent of which party is in power in the neighboring municipalities.

description: We geometrically characterize one-qubit dissipators of a Lindblad type. An efficient parametrization in terms of 6 linear parameters opens the way to various optimizations with local dissipation. As an example, we study maximal steady-state singlet fraction that can be achieved with an arbitrary local dissipation and two qubit Hamiltonian. We show that this singlet fraction has a discontinuity as one moves from unital to non-unital dissipators and demonstrate that the largest possible singlet fraction is approximately 0.654. This means that for systems with a sufficiently entangled ground state there is a fundamental quantum limit to the lowest attainable energy. With local dissipation one is unable to cool the system below some limiting non-zero temperature.

Preserving the Past, Embracing the Future: A Study of the Design Solutions for Fostering Tea Culture Space in Modern Cities for the Younger Generation in China
Creators: Zheng, Zhiying (Peaches)
Publisher: name: University of Alberta Library
Year: 2023

Tea culture in China has a rich history, with roots dating back thousands of years. Despite its cultural significance, there has been a decline in tea culture among the millennial generation in modern cities in China. In an effort to address this issue, this thesis explores the design solutions for fostering tea culture space in modern cities for the millennial generation.

The design of modern tea culture spaces in China's cities has the potential to play a crucial role in connecting millennials with the past, traditions, and cultural heritage. By incorporating historical elements and creating social and communal experiences, these spaces can serve as a bridge between the traditional and the contemporary, promoting a deeper connection to cultural identity and a sense of belonging within a rapidly changing society. While tea culture serves as the main subject of the thesis, the broader aim is to explore how design solutions can foster a renewed appreciation and understanding of cultural heritage among the younger generation.

The research question guiding the study is: How can the use of design solutions to promote tea culture among the millennial generation in modern cities in China serve as a means to connect people with the past, traditions, and cultural heritage? The study provides a historical overview of Chinese tea culture field study, and case studies on the subject. This thesis aims to provide a comprehensive approach to creating tea culture spaces in modern cities in China, going beyond design solutions. The final solution includes the development of a tea brand, the creation of visually appealing packaging, the design of physical spaces, and the use of various design disciplines, such as interior design, furniture and sculpture. Additionally, the research includes the utilization of social media and physical prototyping to inform the design process. The focus is on creating a holistic and immersive experience, rather than simply providing a design solution. The conclusion provides a summary of the research findings and recommendations for future research. The study contributes to the understanding of the role of design in promoting cultural heritage and provides a framework for the development of tea culture spaces that appeal to the millennial generation in modern cities in China.

description: The digitally disruptive environment has evolved rapidly due to the introduction of new advancements within the field of smart applications. Applications of one of the most prominent technologies, Internet of Things (IoT), often appear in the retail sector, where smart services have transformed the customer experience holistically. Presented in this paper are the findings from an exploratory field study in the retail service sector, which drew on the views of experienced practitioners about the smart store experience and the associated changes. The paper presents an overview of the drivers of smart retail service diffusion and the relevant challenges, such as the business expectations and the heterogeneity of devices. The arising themes indicate that IoT security is a major challenge for businesses installing IoT devices in their journey towards smart store transformation. The paper highlights the importance of a secure data-sharing IoT environment that respects customer privacy as the smart experience in-store offers data-driven insights and services. Implications for research and practice are discussed in terms of the customer experience relevant to the identified challenges.

description: We calculate the polarization function of Dirac fermions in metallic armchair graphene nanoribbons for an arbitrary temperature and doping. We find that at finite temperatures due to the phase space redistribution among inter-band and intra-band electronic transitions in the conduction and valence bands, the full polarization function becomes independent of the temperature and the position of the chemical potential. As a result, for a given width of nanoribbons there exists a single plasmon mode, with the energy dispersion determined by the graphene's fine structure constant. In Coulomb-coupled nanoribbons, this plasmon splits into the basic in-phase and out-of-phase plasmon modes, with the splitting energy determined additionally by the inter-ribbon spacing.

description: Joint femtosecond fluorescence upconversion experiments and theoretical calculations provide a hitherto unattained degree of characterization and understanding of the mutagenic etheno adduct 3,N4-etheno-2'-deoxycytidine ($ε$dC) excited state relaxation. This endogenously formed lesion is attracting great interest because of its ubiquity in human tissues and its highly mutagenic properties. The $ε$dC fluorescence is modified with respect to that of the canonical base dC, with a 3-fold increased lifetime and quantum yield at neutral pH. This behavior is amplified upon protonation of the etheno ring ($ε$dCH+). Quantum mechanical calculations show that the lowest energy state $π$$π$*1 is responsible for the fluorescence and that the main nonradiative decay pathway to the ground state goes through an ethene-like conical intersection, involving the out-of-plane motion of the C5 and C6 substituents. This conical intersection is lower in energy than the $π$$π$* state ($π$$π$*1) minimum, but a sizable energy barrier explains the increase of $ε$dC and $ε$dCH+ fluorescence lifetimes with respect to that of dC.

description: The idea of the rule of law is fundamentally based on the idea of a fair trial, and the ideas of "due process" and "the rule of law" are essential to the defence of human rights. Therefore, the core of every legal system must be a mechanism for the assertion of legal rights and the correction of violations via the course of a fair trial in court, as the law is useless without effective remedies. In criminal proceedings, the fairness of the judicial system is especially important since it guards against violations of human rights. Since the death sentence is an irrevocable punishment, constitutional due process and basic justice demand that the judicial functions of trial and sentencing be carried out with fundamental fairness. This article provides a critical analysis of the right to a fair trial in the adversarial System and highlights the difficulties the Indian criminal justice system faces.

description:  How social phenomenon are defined – or framed – is assumed to inform subsequent policy. Yet, the actual relationship between framing and policymaking remains understudied and undertheorized. This article aims to remedy this deficit by drawing on three broad sociological and political science literatures that rarely speak to each other but which together provide insights and theoretical leverage for addressing this question. Specifically, it draws on the literature on social movements and framing, social problem construction, and political theory (on agenda setting, ideas-driven policy, and policy instruments). It presents theoretical propositions for predicting relative consistency between dominant social problem frames and subsequent public policy, in order to animate and guide subsequent research. It argues that the relationship between social problem framing and policymaking – whether seemingly consistent or inconsistent – must be systematically problematized.
Unsupervised Night Image Enhancement: When Layer Decomposition Meets Light-Effects Suppression

description: Night images suffer not only from low light, but also from uneven distributions of light. Most existing night visibility enhancement methods focus mainly on enhancing low-light regions. This inevitably leads to over enhancement and saturation in bright regions, such as those regions affected by light effects (glare, floodlight, etc). To address this problem, we need to suppress the light effects in bright regions while, at the same time, boosting the intensity of dark regions. With this idea in mind, we introduce an unsupervised method that integrates a layer decomposition network and a light-effects suppression network. Given a single night image as input, our decomposition network learns to decompose shading, reflectance and light-effects layers, guided by unsupervised layer-specific prior losses. Our light-effects suppression network further suppresses the light effects and, at the same time, enhances the illumination in dark regions. This light-effects suppression network exploits the estimated light-effects layer as the guidance to focus on the light-effects regions. To recover the background details and reduce hallucination/artefacts, we propose structure and high-frequency consistency losses. Our quantitative and qualitative evaluations on real images show that our method outperforms state-of-the-art methods in suppressing night light effects and boosting the intensity of dark regions.

description: In this paper we take a cross-country perspective to study these issues. Our first objective is to investigate to which extent crime rates are declining in some major developed countries. Specifically, we look at the evolution of crime rates across the two sides of the Atlantic, namely United States and European countries between the 1970 and 2010. A crosscountry perspective is useful insofar we can learn if the apparent decline in crime rates is a global pattern. In doing this, we question the reliability of official crime statistics in assessing the trends in crime rates and some crucial factors impacting on criminal activity. A careful approach at the descriptive and inferential level has been suggested in the last years by several prominent scholars (Aebi, 2004; Dills et al., 2008; Goldberger and Rosenfeld, 2009; Durlauf et al., 2010): crime is a complex and by nature hidden social phenomenon and data need a careful inspection. While in other critical policy sectors data are collected systematically both at national and international level, descriptive information on crime trends across countries are not uniformly and systematically collected (...).

description: Deep Gaussian processes (DGPs) upgrade ordinary GPs through functional composition, in which intermediate GP layers warp the original inputs, providing flexibility to model nonstationary dynamics. Two DGP regimes have emerged in recent literature. A “big data” regime, prevalent in machine learning, favors approximate, optimization-based inference for fast, high-fidelity prediction. A “small data” regime, preferred for computer surrogate modeling, deploys posterior integration for enhanced uncertainty quantification (UQ). We aim to bridge this gap by expanding the capabilities of Bayesian DGP posterior inference through the incorporation of the Vecchia approximation, allowing linear computational scaling without compromising accuracy or UQ. We are motivated by surrogate modeling of simulation campaigns with upwards of 100,000 runs—a size too large for previous fully-Bayesian implementations—and demonstrate prediction and UQ superior to that of “big data” competitors. All methods are implemented in the deepgp package on CRAN. Supplementary materials for this article are available online.

description: Deep Gaussian processes (DGPs) upgrade ordinary GPs through functional composition, in which intermediate GP layers warp the original inputs, providing flexibility to model non-stationary dynamics. Two DGP regimes have emerged in recent literature. A “big data” regime, prevalent in machine learning, favors approximate, optimization-based inference for fast, high-fidelity prediction. A “small data” regime, preferred for computer surrogate modeling, deploys posterior integration for enhanced uncertainty quantification (UQ). We aim to bridge this gap by expanding the capabilities of Bayesian DGP posterior inference through the incorporation of the Vecchia approximation, allowing linear computational scaling without compromising accuracy or UQ. We are motivated by surrogate modeling of simulation campaigns with upwards of 100,000 runs – a size too large for previous fully-Bayesian implementations – and demonstrate prediction and UQ superior to that of “big data” competitors.

2nd release

description: This document reports on the 2nd release of the Atmospheric Thematic services and the software underlying each service. This report, NEANIAS deliverable 3.6, comes out right after the second thematic atmospheric services release, deliverable D3.5.
 The A1 Service, named “ATMO-FLUD”, (for flux densities) provides a set of algorithms for the calculation of flux densities of Sensible Heat, Latent Heat, Turbulent Kinetic Energy and other scalars like GHGs. The input data to the service is user provided although test data are available for trial runs. Real data should be experimentally obtained by the user bearing in mind that the fundamental method employed in this service is the “Eddy Covariance”.
 The A2 Service comprises two services: one named “ATMO-STRESS” calculates the trajectories of tectonic stress based on a series of local data of stress and presents them as a map (stress field). The second service, named “ATMO-SEISM”, compares a series of parameters regarding the seismicity of a region and the variation of gas emission in the atmosphere, in order to find possible correlations.
 The A3 Service, named “ATMO-4CAST”, is responsible for Air quality estimation, monitoring and forecasting, providing users with the ability to obtain and visualize meteorological and air quality forecasts based on their own datasets through a central server. This is done by processing the incoming data, passing it through popular models such as WRF-ARW and CMAQ, and processing and creating visualizations based on their outputs.
 For each released service a point-of-access is provided, as well as an interface through which it may interact with other services, and documentation explaining how to use it. Documentation of all NEANIAS atmospheric services is organized under NEANIAS docs service.
 Services reported here have gone through the second release round, most services have been integrated to NEANIAS authentication system service, the documentation workflow, and integrated with GARR infrastructure services. As expected, this second milestone of services, has the services integrated to NEANIAS core services, have achieved stability in cloud environments and are currently scaling for growing user demands, datasets increment, and output products publication.

Detecting very long-lived gravitational-wave transients lasting hours to weeks

description: We explore the possibility of very long-lived gravitational-wave transients (and detector artifacts) lasting hours to weeks. Such very long signals are both interesting in their own right and as a potential source of systematic error in searches for persistent signals, e.g., from a stochastic gravitational-wave background. We review possible mechanisms for emission on these time scales and discuss computational challenges associated with their detection: namely, the substantial volume of data involved in a search for very long transients can require vast computer memory and processing time. These computational difficulties can be addressed through a form of data compression known as coarse-graining, in which information about short time spans is discarded in order to reduce the computational requirements of a search. Using data compression, we demonstrate an efficient radiometer (cross-correlation) algorithm for the detection of very long transients. In the process, we identify features of a very long transient search (related to the rotation of the Earth) that make it more complicated than a search for shorter transient signals. We implement suitable solutions.

Morphosyntax

description: The selector is a central aspect of the grammar of Gorwaa, and of Southern Cushitic languages in general. But our understanding of the selector is still indeterminate, or even vague. In analysing the Gorwaa selector as an auxiliary verb, using both morphological and distributional evidence, this talk seeks to present a novel analysis, as well as provide a basis for further research on the verbal morphosyntax of Gorwaa.
description: Note: This talk has not gone through a process of peer review, and findings should therefore be treated as preliminary and subject to change.

Excitonic transverse and amplitude fluctuations in the noncollinear and charge-ordered RbFe$^{2+}$Fe$^{3+}$F$_{6}$

description: RbFe$^{2+}$Fe$^{3+}$F$_{6}$ is an example of an antiferromagnet with charge ordering of the octahedrally coordinated Fe$^{2+}$ and Fe$^{3+}$ ions. As well as different spin values, Fe$^{2+}$ ($S=2$) and Fe$^{3+}$ ($S={5\over2}$) possess differing orbital ground states with Fe$^{2+}$ having an orbital degeneracy with an effective orbital angular momentum of $l=1$. The resulting low temperature magnetic structure is non collinear with the spins aligned perpendicular to nearest neighbors (S. W. Kim \textit{et al.} Chem. Sci. {\bf{3}}, 741 (2012)). The combination of an orbital degeneracy and non collinear spin arrangements introduces the possibility for unusual types of excitations such as amplitude modes of the order parameter. In this paper we investigate this by applying a multi-level analysis to model neutron spectroscopy data (M. Songvilay \textit{et al.} Phys. Rev. Lett. {\bf{121}}, 087201 (2018)). In particular, we discuss the possible origins of the momentum and energy broadened continuum scattering observed in terms of amplitude fluctuations allowed through the presence of an orbital degree of freedom on the Fe$^{2+}$ site. We extend previous spin-orbit exciton models based on a collinear spin structure to understand the measured low-energy excitations and also to predict and discuss possible amplitude mode scattering in RbFe$^{2+}$Fe$^{3+}$F$_{6}$.

description: This paper is a sequel to \cite{Choi} in Math. Ann. In that paper we studied the subharmonicity of Kähler-Einstein metrics on strongly pseudoconvex domains of dimension greater than or equal to $3$. In this paper, we study the variations Kähler-Einstein metrics on bounded strongly pseudoconvex domains of dimension $2$. In addition, we discuss the previous result with general bounded pseudoconvex domain and local triviality of a family of bounded strongly pseudoconvex domains.

description: L’hôpital a traditionnellement bénéficié d’une certaine autonomie organisationnelle, qui résultait de la conjonction de l’autonomie des professionnels de santé et de logiques politiques territoriales (Moisdon & Tonneau, 1996). L’hôpital est désormais engagé dans un processus d’intégration bureaucratique tout à la fois diffus, transversal et relativement puissant. Nous proposons d’illustrer les manifestations de ce processus dans les contextes hospitaliers locaux, à partir d’une enquête sur l’introduction des indicateurs nationaux de qualité hospitalière en Aquitaine, première région à avoir expérimenté ces indicateurs, dès 2008, avant leur généralisation à l’ensemble du territoire dans le cadre des procédures nationales de certification.
Growth of power spectrum due to decrease of sound speed during inflation

description: We study the amplification of the curvature perturbations due to a small sound speed and find that its origin is different completely from that due to the ultraslow-roll inflation. This is because when the sound speed is very small the enhancement of the power spectrum comes from the fact that the curvature perturbations at the scales smaller than the cosmic microwave background (CMB) scale becomes scale-variant, rather than growing that leads to the amplification of the curvature perturbations during the ultraslow-roll inflation. At large scales the power spectrum of the curvature perturbations remains to be scale invariant, which is consistent with the CMB observations, and then it will have a transient $k^2$ growth and finally approach a $k^4$ growth as the scale becomes smaller and smaller. Thus the power spectrum can be enhanced to generate a sizable amount of primordial black holes. Furthermore, when the high order correction in the dispersion relation of the curvature perturbations is considered the growth of the power spectrum of the curvature perturbations has the same origin as that in the case without this correction.
