description: The stochastic multi-armed bandit model is a simple abstraction that has proven useful in many different contexts in statistics and machine learning. Whereas the achievable limit in terms of regret minimization is now well known, our aim is to contribute to a better understanding of the performance in terms of identifying the m best arms. We introduce generic notions of complexity for the two dominant frameworks considered in the literature: fixed-budget and fixed-confidence settings. In the fixed-confidence setting, we provide the first known distribution-dependent lower bound on the complexity that involves information-theoretic quantities and holds when m is larger than 1 under general assumptions. In the specific case of two armed-bandits, we derive refined lower bounds in both the fixed-confidence and fixed-budget settings, along with matching algorithms for Gaussian and Bernoulli bandit models. These results show in particular that the complexity of the fixed-budget setting may be smaller than the complexity of the fixed-confidence setting, contradicting the familiar behavior observed when testing fully specified alternatives. In addition, we also provide improved sequential stopping rules that have guaranteed error probabilities and shorter average running times. The proofs rely on two technical results that are of independent interest : a deviation lemma for self-normalized sums (Lemma 19) and a novel change of measure inequality for bandit models (Lemma 1).

We also propose a new method for PageRank problem based on the reduction of this problem to the matrix game. We solve this (sparse) matrix game with randomized mirror descent. It should be mentioned that we used non-standard randomization (in KL-projection) goes back to Grigoriadis-Khachiayn (1995).

Ariadne: Evolving test data using grammatical evolution
Creators: name: Anjum, Muhammad Sheraz
Publisher: name: University of Limerick
Year: 2022

description: Heuristic-based optimization techniques have been increasingly used to automate different types of code coverage analysis. Several studies suggest that interdependencies (in the form of comparisons) may exist between the condition constructs of variables and constant values in the different branching conditions of real-world programs e.g. while(i <= 100) and if(i == j), etc. In this work, by interdependencies we refer to the situations where, in order to satisfy a branching condition, there must be a certain relationship between the values of some specific condition constructs (which may or may not be a part of the respective condition predicates). We propose a Grammatical Evolution (GE)-based test data generator, Ariadne, which employs a novel seeding strategy. Our proposed system employs a simple attribute grammar to exploit different kinds of existing interdependencies (involving both variables and constant values) throughout the search process, which enables it to efficiently evolve complex test data. Our results demonstrate that Ariadne dramatically improves both effectiveness and efficiency when compared with existing GA-based techniques, based upon well-established criteria, attaining high levels of coverage (the standard software testing success metric for these sorts of problems) with far fewer fitness evaluations. Moreover, we also performed rigorous performance and scalability analyses to gain better insights about the working and performance of Ariadne and to examine its scalability, respectively. Our results suggest that the improvements achieved by Ariadne are highly cost-effective and that it remains highly scalable when compared to GA-based test data generation approach.

Open Science Assessment and Incentives at the YUFE Alliance

Publisher: name: Zenodo
Year: 2022

description: While the movement for OS has gained momentum in recent years, there remain concerns about how to recognise researchers’ efforts in OS and how to change the research assessment systems toward more responsible and encompassing ones. Apart from some efforts being taken for example in the Netherlands, there are few examples how universities could embed OS into their incentivisation structures; a gap this project aims to cover. We present two proposals promoted by the YUFE alliance: an OS indicator toolkit for evaluating researchers’ performance in OS and an incentivisation initiative to foster open science at the research group level. These initiatives operate with different incentives (connecting OS performance in recruitment processes; tangible rewards, and advocating OS by showing off institutional forerunner research groups; symbolic rewards). The project provides new insights into the open knowledge landscape within the European YUFE alliance and beyond, and ways of promoting OS paths in the institutional framework.

description: We have developed an analytical method based on forward-modeling techniques to characterize the high-mass end of the red sequence (RS) galaxy population at redshift $z\sim0.55$, from the DR10 BOSS CMASS spectroscopic sample, which comprises $\sim600,000$ galaxies. The method, which follows an unbinned maximum likelihood approach, allows the deconvolution of the intrinsic CMASS colour-colour-magnitude distributions from photometric errors and selection effects. This procedure requires modeling the covariance matrix for the i-band magnitude, g-r colour and r-i colour using Stripe 82 multi-epoch data. Our results indicate that the error-deconvolved intrinsic RS distribution is consistent, within the photometric uncertainties, with a single point ($<0.05~{\rm{mag}}$) in the colour-colour plane at fixed magnitude, for a narrow redshift slice. We have computed the high-mass end ($^{0.55}M_i \lesssim -22$) of the $^{0.55}i$-band RS Luminosity Function (RS LF) in several redshift slices within the redshift range $0.52

description: Learning Spaces are certain set systems that are applied in the mathematical modeling of education. We propose a suitable compression (without loss of information) of such set systems to facilitate their logical and statistical analysis. Under certain circumstances compression is the prerequisite to calculate the Learning Space in the first place.

description: We derive an exact $f(T)$ gravity in the absence of ordinary matter in Friedmann-Robertson-Walker (FRW) universe, where $T$ is the teleparallel torsion scalar. We show that vanishing of the energy-momentum tensor $\mathcal{T}^{μν}$ of matter does not imply vanishing of the teleparallel torsion scalar, in contrast to general relativity, where the Ricci scalar vanishes. The theory provides an exponential (inflationary) scale factor independent of the choice of the sectional curvature. In addition, the obtained $f(T)$ acts just like cosmological constant in the flat space model. Nevertheless, it is dynamical in non-flat models. In particular, the open universe provides a decaying pattern of the $f(T)$ contributing directly to solve the fine-tuning problem of the cosmological constant. The equation of state (EoS) of the torsion vacuum fluid has been studied in positive and negative Hubble regimes. We study the case when the torsion is made of a scalar field (tlaplon) which acts as torsion potential. This treatment enables to induce a tlaplon field sensitive to the symmetry of the spacetime in addition to the reconstruction of its effective potential from the $f(T)$ theory. The theory provides six different versions of inflationary models. The real solutions are mainly quadratic, the complex solutions, remarkably, provide Higgs-like potential.

description: We present integral field spectrograph (IFS) with laser guide star adaptive optics (LGS-AO) observations of z=2 quasi-stellar objects (QSOs) designed to resolve extended nebular line emission from the host galaxy. Our data was obtained with W. M. Keck and Gemini-North Observatories using OSIRIS and NIFS coupled with the LGS-AO systems. We have conducted a pilot survey of five QSOs, three observed with NIFS+AO and two observed with OSIRIS+AO at an average redshift of z=2.15. We demonstrate that the combination of AO and IFS provides the necessary spatial and spectral resolutions required to separate QSO emission from its host. We present our technique for generating a PSF from the broad-line region of the QSO and performing PSF subtraction of the QSO emission to detect the host galaxy. We detect H$α$ and [NII] for two sources, SDSS J1029+6510 and SDSS J0925+06 that have both star formation and extended narrow-line emission. Assuming that the majority of narrow-line H$α$ is from star formation, we infer a star formation rate for SDSS J1029+6510 of 78.4 M$_\odot$yr$^{-1}$ originating from a compact region that is kinematically offset by 290 - 350 km/s. For SDSS J0925+06 we infer a star formation rate of 29 M$_\odot$yr$^{-1}$ distributed over three clumps that are spatially offset by $\sim$ 7 kpc. The null detections on three of the QSOs are used to infer surface brightness limits and we find that at 1.4 kpc distance from the QSO that the un-reddened star formation limit is $

We characterize continuous space-valued sheaves on these conically smooth stratified spaces in terms of tangential data, and we similarly characterize 1-excisive invariants of stratified spaces. These results are based on the existence of open handlebody decompositions for conically smooth stratified spaces, an inverse function theorem, a tubular neighborhood theorem, an isotopy extension theorem, and functorial resolutions of singularities to smooth manifolds with corners.

The State of Unpaywall: Analyzing the Consistency of Open Access Data
Creators: name: Sanford, Henning
Publisher: name: Zenodo
Year: 2022

description: These result highlight the difficulties of identifying the open access status of a publication. Especially for less rigid OA subgroups like Hybrid and Bronze OA the classification task is a process of iterating over improved algorithms. Generally, it can be assumed that these iterations lead towards a more accurate reflection of the true OA status. This process, however, has implications for the academic users of Unpaywall data. Studies that use these data to analyze OA status and especially OA subgroups should be aware that the reliability of the data and reproducibility of the results are dependent on time and infrastructural design choice. This observation poses essential background information for OA studies that rely on Unpaywall data at a single point in time. For the OA transformation, the results also highlight the importance of author-choice based contributions. Publisher-choice based contributions appear to be harder to identify but also volatile in their status over time. For Open Access studies, these findings provide empirical reasons for caution when including data on Bronze OA into their analysis. For the OA transformation in general, the findings highlight authors as the key contributors to a successful transformation.

description: Excerpts from the report: Part I: The purpose of this paper is to present this simple approach to multiple curvilinear correlation. The method employed will be demonstrated with six examples, or cases, of actual problems chosen from different fields of economic relationships, in the hope that this “case” method of presentation will not only make clear the simple steps involved, but will also suggest their application to similar problems likely to be encountered by the analyst of variations in economic data. Part II: The simplified method of correlation already described in considerable detail elsewhere may be further illustrated by applying it to three additional problems dealing with actual changes in acreage, livestock numbers and yields. The cases selected for illustration deal with changes (a) in the United States acreage of cabbage, (b) in the total number of hogs on farms and (c) in the yield per acre of wheat in an eastern State.
A new polarisation amplitude bias reduction method

description: Polarisation amplitude estimation is affected by a positive noise bias, particularly important in regions with low signal-to-noise ratio (SNR). We present a new approach to correct for this bias in the case there is additional information about the polarisation angle. We develop the 'known-angle estimator' that works in the special case when there is an independent and high signal-to-noise ratio ($\gtrsim 2σ$) measurement of the polarisation angle. It is derived for the general case where the uncertainties in the Q,U Stokes parameters are not symmetric. This estimator completely corrects for the polarisation bias if the polarisation angle is perfectly known. In the realistic case, where the angle template has uncertainties, a small residual bias remains, but that is shown to be much smaller that the one left by other classical estimators. We also test our method with more realistic data, using the noise properties of the three lower frequency maps of WMAP. In this case, the known-angle estimator also produces better results than methods that do not include the angle information. This estimator is therefore useful in the case where the polarisation angle is expected to be constant over different data sets with different SNR.

Saturated Graphs of Prescribed Minimum Degree

description: A graph $G$ is $H$-saturated if it contains no copy of $H$ as a subgraph but the addition of any new edge to $G$ creates a copy of $H$. In this paper we are interested in the function sat$_{t}(n,p)$, defined to be the minimum number of edges that a $K_{p}$-saturated graph on $n$ vertices can have if it has minimum degree at least $t$. We prove that sat$_{t}(n,p) = tn - O(1)$, where the limit is taken as $n$ tends to infinity. This confirms a conjecture of Bollobás when $p = 3$. We also present constructions for graphs that give new upper bounds for sat$_{t}(n,p)$ and discuss an analogous problem for saturated hypergraphs.

description: Loop-weighted walk with parameter $λ\geq 0$ is a non-Markovian model of random walks that is related to the loop $O(N)$ model of statistical mechanics. A walk receives weight $λ^{k}$ if it contains $k$ loops; whether this is a reward or punishment for containing loops depends on the value of $λ$. A challenging feature of loop-weighted walk is that it is not purely repulsive, meaning the weight of the future of a walk may either increase or decrease if the past is forgotten. Repulsion is typically an essential property for lace expansion arguments. This article circumvents the lack of repulsion and proves, via the lace expansion, that for any $λ\geq 0$ loop-weighted walk is diffusive in high dimensions.

Borders, Migration, and Technology in the Age of Security: Intervening with STS

Publisher: name: Tecnoscienza – Italian Journal of Science & Technology Studies
Year: 2023

description: In recent years, a broad and multidisciplinary literature has emerged at the intersection of critical border and migration studies, critical security studies, and science and technologies studies (STS). This literature has produced a rich conceptual repertoire for the analysis of digital technologies and infrastructures of border control and mobility governance. This scenario conceptually maps some of the core strands in this debate, which portray borders as complex and multi-located arrangements that create spaces of control and circulation, notions and images of “trusted” and/or “risky” travelers, and a globalized hierarchy of mobility rights. Furthermore, the scenario reflects on some major research avenues for STS to intervene in this debate and expose how border regimes are today imagined, designed, maintained, and critiqued.

description: The integration clause contained in art. 12 TFEU has been rarely invoked in European policymaking. This is due to the generic language adopted by the EU legislator, who does not impose an obligation on the EU bodies to integrate consumer protection in other Union policies or on Member States, thus reducing the justiciability of the provision. Compared to other TFEU provisions dedicated to consumer protection, the strength of art. 12 TFEU seems extremely low. However, art. 12 TFEU may come in handy in the development of a more sustainable economy in which the interests of consumers are not only focused on strengthening the internal market but also on safeguarding the environment and reducing industrial waste. This Article evaluates whether and how art. 12 TFEU may impact the choices of European bodies on the circular economy, the European Green Deal and the re-cent Consumer Agenda strengthening the role of consumers in the green transition.

Year: 2023

description: We consider multi-agent decision making, where each agent optimizes its cost function subject to constraints. Agents’ actions belong to a compact convex Euclidean space and the agents’ cost functions are coupled. We propose a distributed payoff-based algorithm to learn Nash equilibria in the game between agents. Each agent uses only information about its current cost value to compute its next action. We prove convergence of the proposed algorithm to a Nash equilibrium in the game leveraging established results on stochastic processes. The performance of the algorithm is analyzed with a numerical case study.
Study of nonclassicality in tripartite correlations beyond standard Bell nonlocality paradigm

Publisher: name: arXiv
Year: 2014
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In the nonsignaling framework, nonclassicality in correlation arising from two spatially separated input-output devices gets manifested, solely, through its \emph{nonlocal} behavior. Study of correlations based on this said feature is commonly known as local-nonlocal paradigm. While in two-party scenario correlations can be of only two types either local or nonlocal, the situation gets more involved for multi-party scenario, \emph{e.g.,} for tripartite scenario, correlations can be of three types: fully local, two-way local, and genuinely nonlocal. Nonsignaling correlations having quantum realization are termed physical. Fully local and certain quantum realizable two-way local tripartite correlations always have a quantum realization with tripartite biseparable states if there is no restriction on the local Hilbert-space dimensions. In this work, we study the quantum simulation of fully local and two-way local tripartite correlations with restricted local Hilbert-space dimensions, in particular we consider $\mathbb{C}^2\otimes\mathbb{C}^2\otimes\mathbb{C}^2$ quantum systems. Interestingly, in this restricted simulation scenario we find that simulation of certain fully local and two-way local correlations necessarily requires \emph{genuine quantumness} in the three qubit states. This, going beyond the standard nonlocality paradigm, captures a new notion of genuine nonclassicality even in the fully local and two-way local correlations. To explore this newly introduced notion of genuine nonclassicality, we propose two quantities of interest, called \emph{Svetlichny strength} and \emph{Mermin strength}, and extensively study their properties.

description: Old age is at the core of complex constellations composed by media discourses, care and mundane activities, and affective and technological practices that involve a wide range of human and non-human actors. While during the last years concepts such as “active” and “successful” ageing have more and more emphasised the individual responsibility of older adults in managing their own health, in the context of the Covid-19 pandemic elderly have been increasingly framed as vulnerable subjects. This Crossing Boundaries will explore the different instances assumed by the “old age” as an emerging object by the enactment of discourses and materialities. In doing so, this Crossing Boundaries mobilizes different theoretical perspectives, such as STS, media studies and sociology of health. The authors will explore three main issues: 1) the public discourse about the health status of older people; 2) the collective management of Alzheimer’s disease in and outside institutions; 3) the involvement of older adults in designing information and communication technologies.

This provides a theoretical justification for plug-in procedures, for example the use of certain credible sets for sufficiently smooth linear functionals. We use this general approach to construct optimal frequentist confidence sets based on the posterior distribution. We also provide simulations to numerically illustrate our approach and obtain a visual representation of the geometries involved.

We also provide conditions that guarantee uniqueness for solutions to such problems.

description: Let $G$ be an affine group scheme over a noetherian commutative ring $R$. We show that every $G$-equivariant vector bundle on an affine toric scheme over $R$ with $G$-action is extended from $\Spec(R)$ for several cases of $R$ and $G$. We show that given two affine schemes with group scheme actions, an equivalence of the equivariant derived categories implies isomorphism of the equivariant $K$-theories as well as equivariant $K'$-theories.

That Obscure Object of Desire: Some Notes for a Slow Art-Science
Creators: name: Casini, Silvia
Publisher: name: Tecnoscienza – Italian Journal of Science & Technology Studies
Year: 2023

description: Although not a book that can be labelled as “art-science”, the novel Atlante Occidentale (1985), published in English as Lines of Light, was conceived by the Italian writer Daniele Del Giudice during a fieldwork visit at the CERN laboratory in Geneva in the early 1980s. The two protagonists, the writer Ira Epstein and the physicist Pietro Brahe, have a common obsession: the drive to experimentation. Both characters seek to create new tools (machines) out of existing material for understanding reality – Pietro a particle collider, Ira the written word. As I argue in the article, Atlante Occidentale, a work of fiction, makes a point which should be at the core of any attempt to better understand art-science collaboration: art and science are both ways of world-making. The article provides readers with a brief overview of the mainstream narratives on and in art-science collaboration and suggests a series of strategies apt for challenging those narratives. First, I argue that experimentation rather than creativity is the glue making any collaboration between art and science possible. Second, I show the importance for both scholars and artists of carrying out laboratory fieldwork and archival research to access science in the making and, hence, to engage in potentially transformative art-science collaborative work. Finally, I call for a radical rethinking of the scale and syntax of art-science projects given that some of the most successful models of such collaborative endeavours are in deep crisis.

description: Since the Paris Agreement entered into force, climate neutrality and associated compensation schemes are even more on the agenda of politics and companies. Challenges of existing offsetting schemes include the rather theoretical saving scenario and the limited scope of considered impacts. To address some of these limitations, this paper proposes the Circular Ecosystem Compensation (CEC) approach based on monetization of LCA results and Ecosystem Valuation. CEC consists of six steps: i) carrying out a life cycle assessment, ii) reducing the environmental impacts, iii) determining environmental costs applying monetization methods, iv) deriving the environmental value based on restoration costs methods, v) implementing the ecological restoration of ecosystems and vi) monitoring of the renaturation measures. Thus, CEC allows to offset a broad set of environmental impacts beyond climate change (e.g., acidification, eutrophication, land use, water use) in a real ecosystem by renaturation of degraded ecosystems. Environmental burdens and environmental benefits are balanced on a monetary basis, as the renaturation measures are monetized and used to compensate the monetized LCA results, e.g., of a product, organization or individual. In a case study, the implementation of the approach is presented to show the practical implementation of the CEC. The challenges of CEC include the integration of further impact categories, the availability of up-to-date and reliable monetization methods, the asynchrony and time-lag of the compensation from an ecosystem and biodiversity perspective and the proof of cost-efficiency of the renaturation measures. It is further discussed, if CEC can be a step beyond “climate neutrality” towards “environmental neutrality”. The proposed approach should be further tested and is intended to foster progress in more comprehensive and robust offsetting of environmental impacts beyond climate change.
Remaking Intelligence? Of Machines, Media, and Montage

description: Over the last decade, there has been a renewed interest in “artificial intelligence” (AI), notably in the form of “machine learning” (ML). This renewed interest may seem paradoxical, insofar as John McCarthy introduced the term “AI” in the mid-1950s to mark a distinction with ML, championing deductive reasoning over automated induction (e.g., Cardon et al. 2018). By contrast, the current reversal, towards ML-based forms of “AI,” marks the statistical, if not spectacular, revival of automated induction. However, the terms used – revival, renewal, reversal – beg the question of the common ground of the involved alternatives. Taking its cue from recent historical (e.g., Penn 2020), relevant conceptual (e.g., Shanker 1998), and prior critical (e.g., Agre 1997) inquiries, this paper outlines a praxeological answer to the raised question. For the purpose, the paper develops a practice-based video analysis of a recent demonstration of “machine intelligence,” the video demonstration of an “agent system” playing Breakout at “superhuman level,” if not opening the gate for the advent of “general AI” (Hassabis 2017). In examining and engaging in “remaking intelligence” in situ, the paper dwells on the tricky interplay between machines, media, and montage, while making explicit and reflecting upon how particular configurations of “enchanted determinism” (Campolo and Crawford 2020) are staged and locally performed.

description: We use the RTT realization of the quantum affine superalgebra associated with the Lie superalgebra $\mathfrak{gl}(M,N)$ to study its finite-dimensional representations and their tensor products. In the case $\mathfrak{gl}(1,1)$, the cyclicity condition of tensor products of finite-dimensional simple modules is determined completely in terms of zeros and poles of rational functions. This in turn induces cyclicity of some particular tensor products of Kirillov-Reshetikhin modules related to $\mathfrak{gl}(M,N)$.

description: Photoisomerization is a fundamental process in several classes of photoreceptors. Phytochromes sense red and far-red light in their Pr and Pfr states, respectively. Upon light absorption, these states react via individual photoreactions to the other state. Cph1 phytochrome shows a photoisomerization of its phycocyanobilin (PCB) chromophore in the Pfr state with a time constant of 0.7 ps. The dynamics of the PCB chromophore has been described, but whether or not the apoprotein exhibits an ultrafast response too, is not known. Here, we compare the photoreaction of 13C/15N labeled apoprotein with unlabeled apoprotein to unravel ultrafast apoprotein dynamics in Cph1. In the spectral range from 1750 to 1620 cm−1 we assigned several signals due to ultrafast apoprotein dynamics. A bleaching signal at 1724 cm−1 is tentatively assigned to deprotonation of a carboxylic acid, probably Asp207, and signals around 1670 cm−1 are assigned to amide I vibrations of the capping helix close to the chromophore. These signals remain after photoisomerization. The apoprotein dynamics appear upon photoexcitation or concomitant with chromophore isomerization. Thus, apoprotein dynamics occur prior to and after photoisomerization on an ultrafast time-scale. We discuss the origin of the ultrafast apoprotein response with the ‘Coulomb hammer’ mechanism, i.e. an impulsive change of electric field and Coulombic force around the chromophore upon excitation.

description: This work examines the influence of iron oxide nanoparticles (Fe3O4 NPs) on neutron and gamma-ray radiation shielding characteristics of Portland cement paste. Experimental evaluations were supplemented with theoretical studies using NXCom program. Portland cement pastes with 5, 10, 15, 20, and 30 wt% of nanomagnetite cement replacement were produced. Moreover, rheological, early strength development, compressive strength, and mercury intrusion porosimetry (MIP) tests were performed. The results showed that increasing the amount of Fe3O4 NPs in a mix leads to a gradual increment in measured viscosity and yield stress. High nano-Fe3O4 content substantially impeded the early strength development process and led to a decrement in the 7- and 28-day compressive strength of cement paste. The MIP studies exhibited a gradual increment in total porosity, and average pore volume, as nano-Fe3O4 content was increased. All the macroscopic cross-sections of slow, fast and thermal neutrons constantly increased as a result of the addition of magnetite nanoparticles, with their variations being markedly linear. Similarly, gamma attenuation test results indicated that the addition of Fe3O4 powder enhances the shielding capability of paste in the energy range of interest (0.08–2.614 MeV). In conclusion, Fe3O4 nanoparticles can be successfully used in producing lead-free cementitious composites with improved gamma-ray and neutron shielding properties. However, certain drawbacks related to an increment in matrix porosity and thus a decrement in mechanical performance should be taken into account.

description: We describe the definition of Jacobi (generalized)-Lie bialgebras $(({\bf{g}},ϕ_{0}),({\bf{g}}^{*},X_{0}))$ in terms of structure constants of the Lie algebras ${\bf{g}}$ and ${\bf{g}}^{*}$ and components of their 1-cocycles $X_{0}\in {\bf{g}}$ and $ϕ_{0}\in {\bf{g}}^{*}$ in the basis of the Lie algebras. Then, using adjoint representations and automorphism Lie groups of Lie algebras, we give a method for classification of real low dimensional Jacobi-Lie bialgebras. In this way, we obtain and classify real two and three dimensional Jacobi-Lie bialgebras.
