description: Recent years have seen the development of many open-source ML fairness toolkits aimed at helping ML practitioners assess and address unfairness in their systems. However, there has been little research investigating how ML practitioners actually use these toolkits in practice. In this paper, we conducted the first in-depth empirical exploration of how industry practitioners (try to) work with existing fairness toolkits. In particular, we conducted think-aloud interviews to understand how participants learn about and use fairness toolkits, and explored the generality of our findings through an anonymous online survey. We identified several opportunities for fairness toolkits to better address practitioner needs and scaffold them in using toolkits effectively and responsibly. Based on these findings, we highlight implications for the design of future open-source fairness toolkits that can support practitioners in better contextualizing, communicating, and collaborating around ML fairness efforts.

description: We apply the Bayesian framework to assess the presence of a correlation between two quantities. To do so, we estimate the probability distribution of the parameter of interest, $ρ$, characterizing the strength of the correlation. We provide an implementation of these ideas and concepts using python programming language and the pyMC module in a very short ($\sim$130 lines of code, heavily commented) and user-friendly program. We used this tool to assess the presence and properties of the correlation between planetary surface gravity and stellar activity level as measured by the log($R'_{\mathrm{HK}}$) indicator. The results of the Bayesian analysis are qualitatively similar to those obtained via p-value analysis, and support the presence of a correlation in the data. The results are more robust in their derivation and more informative, revealing interesting features such as asymmetric posterior distributions or markedly different credible intervals, and allowing for a deeper exploration. We encourage the reader interested in this kind of problem to apply our code to his/her own scientific problems. The full understanding of what the Bayesian framework is can only be gained through the insight that comes by handling priors, assessing the convergence of Monte Carlo runs, and a multitude of other practical problems. We hope to contribute so that Bayesian analysis becomes a tool in the toolkit of researchers, and they understand by experience its advantages and limitations.

 Abstract: Library aid in research data creation and usage is an important component in preparing researchers for ethical careers. Librarians as research guides, curators and advocates for open access information have been a long-established practice for some academic libraries, and while the topic of data in libraries is frequently discussed, libraries are often without guidance on how to launch these services. This paper explores data services available to online learners offered by R1 and R2 university libraries that academic libraries investigating the inclusion of data services may consider for their own research communities. While the investigator is unable to identify a common framework among these research institutions, study results demonstrate a higher proportion of services and information available in online formats by R1 institutions over R2 institutions.

description: We utilize electron counting techniques to distinguish a spin conserving fast tunneling process and a slower process involving spin flips in AlGaAs/GaAs-based double quantum dots. By studying the dependence of the rates on the interdot tunnel coupling of the two dots, we find that as many as 4% of the tunneling events occur with a spin flip related to spin-orbit coupling in GaAs. Our measurement has a fidelity of 99 % in terms of resolving whether a tunneling event occurred with a spin flip or not.

description: There are 134,459 distinct initial hands at the video poker game Jacks or Better, taking suit exchangeability into account. A computer program can determine the optimal strategy (i.e., which cards to hold) for each such hand, but a complete list of these strategies would require a book-length manuscript. Instead, a hand-rank table, which fits on a single page and reproduces the optimal strategy perfectly, was found for Jacks or Better as early as the mid 1990s. Is there a systematic way to derive such a hand-rank table? We show that there is indeed, and it involves finding the exact optimal conditional expected return, given the initial hand. In the case of Jacks or Better (paying 800, 50, 25, 9, 6, 4, 3, 2, 1, 0), this is a random variable with 1,153 distinct values, of which 766 correspond to garbage hands for which it is optimal to draw five new cards. We describe the hands corresponding to each of the remaining 387 values of the optimal conditional expected return (sorted from largest to smallest) and show how this leads readily to an optimal strategy hand-rank table for Jacks or Better. Of course, the method applies to other video poker games as well.

description: Federated learning (FL) with its data privacy protection and communication efficiency has been considered as a promising learning framework for beyond-5G/6G systems. We consider a scenario where a group of downlink non-FL users are jointly served with a group of FL users using massive multiple-input multiple-output technology. The main challenge is how to utilise the resource to optimally serve both FL and non-FL users. We propose a communication scheme that serves the downlink of the non-FL users (UEs) and the uplink of FL UEs in each half of the frequency band. We formulate an optimization problem for optimizing transmit power to maximize the minimum effective data rates for non-FL users, while guaranteeing a quality-of-service time of each FL communication round for FL users. Then, a successive convex approximation-based algorithm is proposed to solve the formulated problem. Numerical results confirm that our proposed scheme significantly outperforms the baseline scheme.

description: This session will promote the cross-border collaboration needed to develop global research infrastructures for 2020 and beyond. Three EC-funded projects will join forces to showcase the development, deployment and operation of research e-infrastructures in different regions of the world. During the session projects will introduce their approaches on these issues and will stimulate discussions about the benefits of developing new world class research e-Infrastructures for the R&D communities. The aim of the session is to underline the necessity of establishing e-infrastructures as a sustainable utility and exploiting them as a factor of innovation in order to ensure that the wider scientific community in Europe and further afield are part of a truly connected world; it will therefore show how these three projects are working hand-in-hand to develop these global research infrastructures. The session has been accepted to be held at the TERENA Networking Conference 2016 (https://tnc16.geant.org/).

description: Since the stacking order sensitively affects various physical properties of layered materials, accurate determination of the stacking order is important for studying the basic properties of these materials as well as for device applications. Because 2H-molybdenum disulfide (MoS2) is most common in nature, most studies so far have focused on 2H-MoS2. However, we found that the 2H, 3R, and mixed stacking sequences exist in few-layer MoS2 exfoliated from natural molybdenite crystals. The crystal structures are confirmed by HR-TEM measurements. The Raman signatures of different polytypes are investigated by using 3 different excitation energies which are non-resonant and resonant with A and C excitons, respectively. The low-frequency breathing and shear modes show distinct differences for each polytype whereas the high-frequency intra-layer modes show little difference. For resonant excitations at 1.96 and 2.81 eV, distinct features are observed which enable determination of the stacking order.

description: Two dimensional materials are becoming increasingly popular as a platform for studies of quantum phenomena and for the production of prototype quantum technologies. Quantum emitters in 2D materials can host two level systems that can act as qubits for quantum information processing. Here, we characterize the behavior of position-controlled quantum emitters in hexagonal boron nitride at cryogenic temperatures. Over two dozen sites, we observe an ultra-narrow distribution of the zero phonon line at ~436 nm, together with strong linearly polarized emission. We employ resonant excitation to characterize the emission lineshape and find spectral diffusion and phonon broadening contribute to linewidths in the range 1-2 GHz. Rabi oscillations are observed at a range of resonant excitation powers, and under 1 $μ$W excitation a coherent superposition is maintained up to 0.90 ns. Our results are promising for future employment of quantum emitters in hBN for scalable quantum technologies.

description: The spin-1 Ising-Heisenberg diamond chain with the second-neighbor interaction between the nodal spins is rigorously solved using the transfer-matrix method. Exact results for the ground state, magnetization process and specific heat are presented and discussed in particular. It is shown that the further-neighbor interaction between the nodal spins gives rise to three novel ground states with a translationally broken symmetry, but at the same time, it does not increases the total number of intermediate plateaus in a zero-temperature magnetization curve compared with the simplified model without this interaction term. The zero-field specific heat displays interesting thermal dependencies with a single- or double-peak structure.

description: Noise is one of the primary quality-of-life issues in urban environments. In addition to annoyance, noise negatively impacts public health and educational performance. While low-cost sensors can be deployed to monitor ambient noise levels at high temporal resolutions, the amount of data they produce and the complexity of these data pose significant analytical challenges. One way to address these challenges is through machine listening techniques, which are used to extract features in attempts to classify the source of noise and understand temporal patterns of a city's noise situation. However, the overwhelming number of noise sources in the urban environment and the scarcity of labeled data makes it nearly impossible to create classification models with large enough vocabularies that capture the true dynamism of urban soundscapes In this paper, we first identify a set of requirements in the yet unexplored domain of urban soundscape exploration. To satisfy the requirements and tackle the identified challenges, we propose Urban Rhapsody, a framework that combines state-of-the-art audio representation, machine learning, and visual analytics to allow users to interactively create classification models, understand noise patterns of a city, and quickly retrieve and label audio excerpts in order to create a large high-precision annotated database of urban sound recordings. We demonstrate the tool's utility through case studies performed by domain experts using data generated over the five-year deployment of a one-of-a-kind sensor network in New York City.

description: The world is in constant technological evolution, and this evolution is not only changing the way people communicate, interact, and have fun, but it is also reshaping teaching and learning. One of the most recent and promising innovations in this field is the concept of the metaverse, a shared virtual reality, whose boundaries between the physical and digital world become almost indistinguishable. Embarking on a transformed journey to learning, as the infinite opportunities and impact of the metaverse on education are explored is exciting, to say the least, and will bring a new movement to education, which is certainly already a transformative journey to learning. and a path of no return. Based on the foregoing, there is an emerging need to explore this topic more deeply, especially since it is a current and innovative topic, whose scientific publications are scarce.

description: We study the effect of impurity scattering effect in black phosphorurene (BP) in this work. For single impurity, we calculate impurity induced local density of states (LDOS) in momentum space numerically based on tight-binding Hamiltonian. In real space, we calculate LDOS and Friedel oscillation analytically. LDOS shows strong anisotropy in BP. Many impurities in BP are investigated using $T$-matrix approximation when the density is low. Midgap states appear in band gap with peaks in DOS. The peaks of midgap states are dependent on impurity potential. For finite positive potential, the impurity tends to bind negative charge carriers and vise versa. The infinite impurity potential problem is related to chiral symmetry in BP.

description: We construct a microscopic model of low-dissipation engines by driving a Brownian particle in a time-dependent harmonic potential. Shortcuts to adiabaticity and shortcuts to isothermality are introduced to realize the adiabatic and isothermal branches in a thermodynamic cycle, respectively. We derive an analytical expression of the efficiency at maximum power for this kind of engines. This expression satisfies the universal law of efficiency at maximum power up to the second order of the Carnot efficiency. We also analyze the issue of power at any given efficiency for general low-dissipation engines, and then obtain the supremum of the power in three limiting cases respectively.

On the example of the three-dimensional Ising model at criticality and using the simplest implementation of the FRG, we compute the probability distribution functions of the order parameter or equivalently its logarithm, called the rate functions in large deviations theory. We compute the entire family of universal scaling functions, obtained in the limit where the system size $L$ and the correlation length of the infinite system $ξ_{\infty}$ diverge, with the ratio $ζ=L/ξ_{\infty}$ held fixed. It compares very accurately with numerical simulations.

description: With the AfricaConnect series of projects, the lack of access to e-Infrastructures in Africa by African scientists is going to be tackled and hopefully solved. In the recently ended eI4Africa project it has been demonstrated clearly that it is possible to develop e-Infrastructures in Africa and that easy to use web portals, namely Science Gateways, are needed to help Communities of Practice (CoPs) in various scientific disciplines to easily access e-Infrastructure facilities and through these collaborate with CoPs in Europe and across the world. This paper presents the Sci-GaIA project which is the successor of eI4Africa. Sci-GaIA proposes to create clearly structured guides and educational materials that can be used to train and support representatives of NRENs, CoPs and, importantly, Universities to develop Science Gateways and other e-Infrastructures services. Sci-GaIA also plans to work with new and emerging CoPs to develop these technologies and to strengthen e-Infrastructure service provision, especially in terms of identity federations and open access linked data repositories. The paper has been submitted to AFRICOMM 2015.
Protocol for "Adult Use Cannabis Legalization: A Scoping Review of Outcome Monitoring Recommendations"
Creators: name: O'Grady, Megan
Publisher: name: figshare
Year: 2023
Subjects: classificationCode: 420603
subject: Health promotion

description: Objective: We propose to conduct a scoping review to understand the potential size and scope of literature that makes recommendations about the outcomes that States, counties, and/or municipalities in the United States may aim to monitor as they are planning and undergoing adult use cannabis legalization.Introduction: Legalization of adult use cannabis continues to expand across the United States. From a public health perspective, monitoring of cannabis outcomes is important to understand health, social, and financial impacts of legalization, which in turn may inform state and national policies regarding adult use cannabis legalization. This scoping review will identify the scope and size of the literature on cannabis outcome monitoring and provide valuable insights to enhance evidence-based decision-making, data monitoring and national policy development.Inclusion criteria: The inclusion criteria requires papers to offer recommendations on outcomes, measures, and or topical areas that should be monitored and should be specific to adult-use cannabis legalization. The scope of eligible papers encompasses policy/commentary articles, reviews, and empirical studies. The exclusion criteria excludes papers that are not published in the English language, that do not discuss recommendations specific to the United States, that are mainly an empirical study in which outcome monitoring recommendations are made in the discussion section with limited scope, or that are not relevant to adult use cannabis legalization (e.g., focus on medical cannabis legalization only).Methods: PubMed/MEDLINE, Embase, Scopus, PsycInfo, Web of Science, Dissertations & Theses Global, the Trip Database, and the RAND website will be searched from date of inception to 8/16/2023 to retrieve all relevant records. We will also identify relevant reports from the CTSE website. Two reviewers will screen abstracts and titles to identify the initial set of articles to be considered. Disagreements will be solved via discussion and third party advice as necessary and inter-rater reliability of screening results will be calculated. They will then assess full text articles for final inclusion. Included articles will be coded using a standardized form. Findings will be organized using PRISMA for scoping reviews (PRISMA-ScR).
D8.2.1 Life Cycle Cost Assessment (LCCA) - Report

Publisher: name: Zenodo
Year: 2023

description: The report covers the first phase (M25 report) of the D8.2 that focuses on the assessment of the economic impacts of ASTEP modular systems throughout the life cycle. It includes a systematic literature review on the economic impact of different solar thermal plants like parabolic trough (PT), linear Fresnel (LFR), solar tower (ST) and solar dish (SD) plants. Different types of financial metrics like levelized cost of Energy (LCOE), net present value (NPV), investment/capital cost, total life cycle cost (TLCC), payback period, benefit- cost ratio (BRC), internal rate of return (IRR) and revenues were considered. It was found that ST plant had a lower average Levelized Cost of Energy (LCOE) than the PT plant at 100 MW and 200 MW capacity. The ST plant had a higher average NPV than the PT plant at 50 MW and 100 MW capacity. A lack of studies on the external environmental costs of solar thermal plants was observed. There is a need for more research in the economic assessment of solar thermal plants with capacities below 50 MW and above 100 MW to enable the economic comparison of solar thermal plants of different plant capacities.
 The report covers economic LCA of the ASTEP system that will be developed and applied on two end-users, Mandrekas & ArcelorMittal, located in Greece and Romania, at two different latitudes. Finally, the report explains the development of a new software tool using dynamic LCA to improve the results of the static LCA of the ASTEP system. The LCA tool will be used for the environmental and economic assessment of the systems that use solar thermal energy and high temperatures to provide heating and cooling for industrial processes such as the ASTEP system.

First, we study the structure of positive harmonic functions of H and give their precise behavior. Second, under quite general conditions we prove an upper bound for the correspond heat kernel p(x, y, t) of the type 0 \textless{} p(x, y, t) $\le$ C t -- N 2 U (min{|x|, $\sqrt$ t})U (min{|y|, $\sqrt$ t}) U ($\sqrt$ t) 2 exp -- |x -- y| 2 Ct for all x, y $\in$ R N and t \textgreater{} 0, where U is a positive harmonic function of H. Third, if U 2 is an A 2 weight on R N , then we prove a lower bound of a similar type.

description: In general, flat outputs of a nonlinear system may depend on the system's state and input as well as on an arbitrary number of time derivatives of the latter. If a flat output which also depends on time derivatives of the input is known, one may pose the question whether there also exists a flat output which is independent of these time derivatives, i.e., an (x,u)-flat output. Until now, the question whether every flat system also possesses an (x,u)-flat output has been open. In this contribution, this conjecture is disproved by means of a counterexample. We present a two-input system which is differentially flat with a flat output depending on the state, the input and first-order time derivatives of the input, but which does not possess any (x,u)-flat output. The proof relies on the fact that every (x,u)-flat two-input system can be exactly linearized after an at most dim(x)-fold prolongation of one of its (new) inputs after a suitable input transformation has been applied.

description: We deal with direct and inverse problems of the calculus of variations on arbitrary time scales. Firstly, using the Euler-Lagrange equation and the strengthened Legendre condition, we give a general form for a variational functional to attain a local minimum at a given point of the vector space. Furthermore, we provide a necessary condition for a dynamic integro-differential equation to be an Euler-Lagrange equation (Helmholtz's problem of the calculus of variations on time scales). New and interesting results for the discrete and quantum settings are obtained as particular cases. Finally, we consider very general problems of the calculus of variations given by the composition of a certain scalar function with delta and nabla integrals of a vector valued field.

description: Being able to release and exploit open data gathered in information systems is crucial for researchers, enterprises and the overall society. Yet, these data must be anonymized before release to protect the privacy of the subjects to whom the records relate. Differential privacy is a privacy model for anonymization that offers more robust privacy guarantees than previous models, such as $k$-anonymity and its extensions. However, it is often disregarded that the utility of differentially private outputs is quite limited, either because of the amount of noise that needs to be added to obtain them or because utility is only preserved for a restricted type and/or a limited number of queries. On the contrary, $k$-anonymity-like data releases make no assumptions on the uses of the protected data and, thus, do not restrict the number and type of doable analyses. Recently, some authors have proposed mechanisms to offer general-purpose differentially private data releases. This paper extends such works with a specific focus on the preservation of the utility of the protected data. Our proposal builds on microaggregation-based anonymization, which is more flexible and utility-preserving than alternative anonymization methods used in the literature, in order to reduce the amount of noise needed to satisfy differential privacy. In this way, we improve the utility of differentially private data releases. Moreover, the noise reduction we achieve does not depend on the size of the data set, but just on the number of attributes to be protected, which is a more desirable behavior for large data sets. The utility benefits brought by our proposal are empirically evaluated and compared with related works for several data sets and metrics.

description: Using high-statistics datasets generated in (2+1)-flavor QCD calculations at finite temperature we construct estimators for the radius of convergence from an eighth order series expansion of the pressure as well as the number density. We show that the estimator for pressure and number density will be identical in the asymptotic limit. In the vicinity of the pseudo-critical temperature, $T_{pc}\simeq 156.5$~MeV, we find the estimator of the radius of convergence to be $μ_B/T \gtrsim\ 3$ for strangeness-neutral matter. We also present results for the pole structure of the Padé approximants for the pressure at non-zero values of the baryon chemical potential and show that the pole structure of the [4,4] Padé is consistent with not having a critical point at temperatures larger than $135~$MeV and a baryon chemical potential smaller than $μ_B/T \sim \ 2.5$.

description: Superior corporate governance forms the bedrock of a prosperous economy. An integral component of outstanding corporate governance is the role of transparent, accurate and freely available information with respect to a company’s books and records. Numerous stakeholders including current and potential investors, business partners, employees, regulators and the public, rely on the integrity of the financial reporting. The law on external auditors in Jordan has undergone significant improvement, yet substantial gaps exist between current law and best 113 VOL. 11 (2023) practices. The Article focuses on the role of the auditor in ensuring superior corporate governance. The goal of this Article is to assess the legal regime of the external auditors as provided in the Jordanian Company Legislation of 1997 and its amendments, as shareholder jurisdiction, with the UK Companies Act of 2006 and, at the same time, to provide suggestions for improvement in the current legal regime. Then, the Article presents the general perspective of the duties and obligations of external auditors in the context of corporate governance noting various shortcomings and inconsistencies between rights and duties of auditors. The Article sheds light on some of the major global financial scandals. Finally, the Article analyzes in detail the specific provisions related to external auditors in Jordan and UK laws.

description: Gaia Data Release 3 provides novel flux-calibrated low-resolution spectrophotometry for about 220 million sources in the wavelength range 330nm - 1050nm (XP spectra). Synthetic photometry directly tied to a flux in physical units can be obtained from these spectra for any passband fully enclosed in this wavelength range. We describe how synthetic photometry can be obtained from XP spectra, illustrating the performance that can be achieved under a range of different conditions - for example passband width and wavelength range - as well as the limits and the problems affecting it. Existing top-quality photometry can be reproduced within a few per cent over a wide range of magnitudes and colour, for wide and medium bands, and with up to millimag accuracy when synthetic photometry is standardised with respect to these external sources. Some examples of potential scientific application are presented, including the detection of multiple populations in globular clusters, the estimation of metallicity extended to the very metal-poor regime, and the classification of white dwarfs. A catalogue providing standardised photometry for ~220 million sources in several wide bands of widely used photometric systems is provided (Gaia Synthetic Photometry Catalogue; GSPC) as well as a catalogue of $\simeq 10^5$ white dwarfs with DA/non-DA classification obtained with a Random Forest algorithm (Gaia Synthetic Photometry Catalogue for White Dwarfs; GSPC-WD).

description: We review the history and status of the famous classification of extraterrestrial civilizations given by the great Russian astrophysicist Nikolai Semenovich Kardashev, roughly half a century after it has been proposed. While Kardashev's classification (or Kardashev's scale) has often been seen as oversimplified, and multiple improvements, refinements, and alternatives to it have been suggested, it is still one of the major tools for serious theoretical investigation of SETI issues. During these 50+ years, several attempts at modifying or reforming the classification have been made; we review some of them here, together with presenting some of the scenarios which present difficulties to the standard version. Recent results in both theoretical and observational SETI studies, especially the G-hat infrared survey (2014-2015), have persuasively shown that the emphasis on detectability inherent in Kardashev's classification obtains new significance and freshness. Several new movements and conceptual frameworks, such as the Dysonian SETI, tally extremely well with these developments. So, the apparent simplicity of the classification is highly deceptive: Kardashev's work offers a wealth of still insufficiently studied methodological and epistemological ramifications and it remains, in both letter and spirit, perhaps the worthiest legacy of the SETI "founding fathers".

description: In this letter, an effective image saliency detection method is proposed by constructing some novel spaces to model the background and redefine the distance of the salient patches away from the background. Concretely, given the backgroundness prior, eigendecomposition is utilized to create four spaces of background-based distribution (SBD) to model the background, in which a more appropriate metric (Mahalanobis distance) is quoted to delicately measure the saliency of every image patch away from the background. After that, a coarse saliency map is obtained by integrating the four adjusted Mahalanobis distance maps, each of which is formed by the distances between all the patches and background in the corresponding SBD. To be more discriminative, the coarse saliency map is further enhanced into the posterior probability map within Bayesian perspective. Finally, the final saliency map is generated by properly refining the posterior probability map with geodesic distance. Experimental results on two usual datasets show that the proposed method is effective compared with the state-of-the-art algorithms.
