description: Classical mathematics (involving such notions as infinitely small/large and continuity) is usually treated as fundamental while finite mathematics is treated as inferior which is used only in special applications. We first argue that the situation is the opposite: classical mathematics is only a degenerate special case of finite one and finite mathematics is more pertinent for describing nature than standard one. Then we describe results of a quantum theory based on finite mathematics. Implications for foundation of mathematics are discussed.

Publisher: name: IFAC - International Federation of Automatic Control

description: This paper considers the synchronization problem of multi-agent SISO systems with general unidirectional communication structures. A distributed control strategy is presented which relies on relative output differences of neighboring agents and, thus, does not need relative state information. We propose a root locus design method to determine the synchronization gain. Since in directed networks the characteristic equation for synchronization might be complex valued, we use tools from the complex root locus technique to solve the synchronization task.
Promising Technosciences in the Economy of Attention: Why Have Pessimistic Stories of Disruption and “Artificial Intelligence” Performed so Well?
Creators: name: Audétat, Marc
Publisher: name: Tecnoscienza – Italian Journal of Science & Technology Studies
Year: 2023

description: The promises connected to emerging science and technology do not merely assist research and innovation, but are a part of it. Their diverse roles in producing hype and ensuring coordination have been extensively studied in the sociology of expectations. However, promises also circulate on a massive scale in the media sphere, as occurred with nanotechnology and artificial intelligence, recounting what the future will be like. The popularity that technoscientific visions manage to attract is less well studied and understood, although it is closely connected with how research is directed and innovation funded – and thus deserves more attention. This contribution explains why so much promising and visioneering is taking place, identifies a “regime of promising”, and discusses its implications for the relationship between science and society. Drawing on cultural and media studies to expand the sociology of expectations, it attempts to better understand the role of fiction in building socio-technical imaginaries.

description: When the kinetic energy of a collection of interacting two-dimensional (2D) electrons is quenched at very high magnetic fields so that the Coulomb repulsion dominates, the electrons are expected to condense into an ordered array, forming a quantum Wigner crystal (WC). Although this exotic state has long been suspected in high-mobility 2D electron systems at very low Landau level fillings ($ν<<1$), its direct observation has been elusive. Here we present a new technique and experimental results that directly probe the magnetic-field-induced WC. We measure the magneto-resistance of a bilayer electron system with unequal layer densities at high magnetic fields. One layer has a very low density and is in the WC regime ($ν<<1$), while the other ("probe") layer is near $ν=1/2$ and hosts a sea of composite fermions, quasi-particles formed by attaching two flux-quanta to each interacting electron. The composite fermions feel the periodic electric potential of the WC in the other layer and exhibit magneto-resistance maxima whenever their cyclotron orbit encircles certain integer number of the WC lattice points. The positions of the maxima reveal that the WC has a triangular lattice and yield a direct measure of its lattice constant. Our results provide a striking example of how one can probe an exotic many-body state of 2D electrons using equally exotic quasi-particles of another many-body state.

description: Advancements in Machine Learning (ML) techniques and satellite imagery in the last decade has enabled us to build and deploy scalable agricultural monitoring systems. However, challenges exist for expanding these solutions across the global development sector. Supervised ML models rely on high quality training data to learn the relationship between input and target variables. In many agricultural applications, training data is generated from ground reference data that is matched with corresponding satellite imagery. However, ground reference data collection is an extensive and expensive effort, and extremely scarce in remote and dangerous areas that would most benefit from remote sensing. In this project, we use a novel ML technique, Generative Adversarial Networks (GAN), to generate synthetic training data from multispectral satellite imagery.
Caratterizzazione del sistema attivatore del plasminogeno nella progressione metastatica del cancro prostatico umano

description: GnRH analogues are used for the treatment of prostate cancer (PCa) because their ability to suppress the activity of the pituitary-testicular axis, with consequent blockade of testosterone production. However, after an initial responsiveness to hormonal deprivation, PCa progresses and then metastatises. It is known that the system of the plasminogen activator (uPA, uPA inhibitors PAI-1/2 and uPA receptor, uPAR) has been involved in the local degradation of the extracellular matrix and PCa progression and metastases. Studies performed in our laboratory have demonstrated the presence of GnRH receptors, suggesting a direct effect of GnRH analogues in inhibiting the proliferation of human PCa cell lines. The aim of this study was to test the effect of an agonist (Leuprolide) and an antagonist (Cetrorelix) of GnRH on uPA/uPAR and PAI-1 expression and activity, on the migratory and invasion capabilities in the two androgen-independent cell lines, DU145 and PC3 cells. The results obtained in DU145 and PC3 cells show that both Leuprolide and Cetrorelix: 1) significantly decrease the enzymatic activity of uPA; 2) induce a marked decrease of uPA and a significant increase of PAI-1 protein levels; 3) increase the presence of soluble uPAR in the cell media; 4) decrease the migratory and invasion capabilities. In conclusions, GnRH analogues might interfere with the mechanisms of metastatic progression of human androgen-independent PCa by inhibiting the activity of the plasminogen activator system.

description: About 15 years ago, Jo Shaw asserted that what is the current art. 10 TFEU was "largely an empty vessel". Several years down the road, the present Article takes Shaw's statement as a starting point to ex-amine the two articles of the current EU Treaties that are most commonly associated with the idea of equality mainstreaming in contemporary EU law: art. 8 TFEU and art. 10 TFEU (section I). It is argued that these articles rather than fulfilling a new function, actually primarily illustrate and give visibility to a political will to use existing tools to enhance the protection of equal treatment in EU law. We will explain first why these articles taken in isolation can still be considered an empty vessel (section II). Yet, although the horizontal clauses have not had much added value, they have actually been used. We therefore subsequently explore how the clauses have been employed, both in ECJ case-law and in a broader EU governance context (section III). By way of concluding comments, we investigate the existence of other possible avenues for improving the equality agenda in the EU legal order (section IV).
Incidence Bounds for Block Designs

description: We prove three theorems giving extremal bounds on the incidence structures determined by subsets of the points and blocks of a balanced incomplete block design (BIBD). These results generalize and strengthen known bounds on the number of incidences between points and $m$-flats in affine geometries over finite fields. First, we show an upper bound on the number of incidences between sufficiently large subsets of the points and blocks of a BIBD. Second, we show that a sufficiently large subset of the points of a BIBD determines many t-rich blocks. Third, we show that a sufficiently large subset of the blocks of a BIBD determines many t-rich points. These last two results are new even in the special case of incidences between points and $m$-flats in an affine geometry over a finite field. As a corollary we obtain a tight bound on the number of t-rich points determined by a set of points in a plane over a finite field, and use it to sharpen a result of Iosevich, Rudnev, and Zhai on the number of triangles with distinct areas determined by a set of points in a plane over a finite field.

The Roots of Neglect: Towards a Sociology of Non-Imagination
Creators: name: Prainsack, Barbara
Publisher: name: Tecnoscienza – Italian Journal of Science & Technology Studies
Year: 2023

description: The sociology of expectations has helped academics and policy analysts to understand how socio-technical imaginaries are not only hypothetical and “in the future”, but how they create realities in the present. They do so by shaping what gets funded, who gets hired, and even how people lead their lives as they consider some futures more likely than others. While this focus on the performative power of specific visions and expectations has been hugely important, there is another situation that has arguably been at least equally impactful on the present: the absence of (alternative) expectations of the future. It is the absence of specific imaginations of the future that people deem desirable that explains why, despite being fully aware of political and economic practices and arrangements that are detrimental for human and planetary health, we have not changed these arrangements.

Year: 2023

description: In the last decade, science and technology studies have paid increasing attention to the role of futures, anticipatory expectations, and forward-looking statements in co-defining the nexus between science, technology and society. This broad interest is articulated into several research streams, from the assessment of long-term futures of technological innovation and setting out how future-oriented socio-technical imaginaries act upon real-time technoscientific innovation to actionable anticipatory frameworks and scenarios adopted to intervene in science, technology and innovation governance. This paper introduces the special section Disentangling Features, which collects four lectures from the teaching and mutual learning activities held during the VI STS Italia Summer School, organised at the University of Padova in September 2022. By situating the four lectures within a composite conceptual framework, the paper discusses the relationship between the future and technoscientific processes in the context of science and technology studies with an emphasis on the performative role of futures and imaginaries in co-shaping knowledge-making practices and technological developments.

description: 3D printers based on the Fused Decomposition Modeling create objects layer-by-layer dropping fused material. As a consequence, strong overhangs cannot be printed because the new-come material does not find a suitable support over the last deposed layer. In these cases, one can add some support structures (scaffolds) which make the object printable, to be removed at the end. In this paper we propose a level set method to create object-dependent support structures, specifically conceived to reduce both the amount of additional material and the printing time. We also review some open problems about 3D printing which can be of interests for the mathematical community.

Year: 2014
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: We construct spherically symmetric solutions to the Einstein-Euler equations, which give models of gaseous stars in the framework of the general theory of relativity. We assume a realistic barotropic equation of state. Equilibria of the spherically symmetric Einstein-Euler equations are given by the Tolman-Oppenheimer-Volkoff equations, and time periodic solutions around the equilibrium of the linearized equations can be considered. Our aim is to find true solutions near these time-periodic approximations. Solutions satisfying so called physical boundary condition at the free boundary with the vacuum will be constructed using the Nash-Moser theorem. This work also can be considered as a touchstone in order to estimate the universality of the method which was originally developed for the non-relativistic Euler-Poisson equations.

title: Dynamic corrosion risk assessment in the oil and gas production and processing facility
Creators: name: Taleb Berrouane, Mohammed
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Corrosion is a major cause of process equipment deterioration in the oil and gas industry. It represents a significant threat to asset integrity and process safety. Corrosion can lead to leakage, which subsequently, leads to contamination by the spill of hazardous materials, vapour cloud explosions or toxic releases, depending on the geolocation and nature of the fluid carried inside the process equipment. For metal structures, the deteriorative process caused by corrosion reduces the residual ultimate strength leading to structural failure when exceeding the total stress. Localized corrosion is reported to be the most hazardous form of corrosion leading to catastrophic failures. Among corrosion modes, microbiologically influenced corrosion (MIC) is particularly complex to predict, detect and mitigate. Hence, significant attention should be given to prediction of the occurrence of MIC and assessment of the associated risks. Several studies by microbiologists and corrosion scientists focused on the understanding of MIC initiation and development mechanisms. However, in-depth assessment of MIC susceptibility and risk quantification is still lacking. This thesis advances the understanding of MIC susceptibility and risk assessment by providing enhanced probabilistic models developed to fit the complexity of the microbiological corrosive process. Bayesian analysis was employed to assess the potential of having MIC while considering: chemical, physical, biological and molecular variables. A new modelling tool based on Stochastic Petri-nets enhanced with Bayesian updating capabilities was developed to address the main shortcomings of traditional Bayesian networks. This work also proposes an MIC risk assessment framework using Bow-Tie analysis and a corrosion resilience model based on Stochastic Petri-nets. The application of the proposed methods is demonstrated using different case studies. The outcomes of this research provide advanced probability-based methods adapted to the corrosion field. Application of the proposed methods enhances the prediction and remediation of localized corrosion processes, especially MIC.

description: We investigate the approximation of the Monge problem (minimizing \int\_$Ω$ |T (x) -- x| d$μ$(x) among the vector-valued maps T with prescribed image measure T \# $μ$) by adding a vanishing Dirichlet energy, namely $ε$ \int\_$Ω$ |DT |^2. We study the $Γ$-convergence as $ε$ $\rightarrow$ 0, proving a density result for Sobolev (or Lipschitz) transport maps in the class of transport plans. In a certain two-dimensional framework that we analyze in details, when no optimal plan is induced by an H ^1 map, we study the selected limit map, which is a new "special" Monge transport, possibly different from the monotone one, and we find the precise asymptotics of the optimal cost depending on $ε$, where the leading term is of order $ε$| log $ε$|.

Some results of algebraic geometry over Henselian rank one valued fields

description: We develop geometry of affine algebraic varieties in $K^{n}$ over Henselian rank one valued fields $K$ of equicharacteristic zero. Several results are provided including: the projection $K^{n} \times \mathbb{P}^{m}(K) \to K^{n}$ and blow-ups of the $K$-rational points of smooth $K$-varieties are definably closed maps, a descent property for blow-ups, curve selection for definable sets, a general version of the Łojasiewicz inequality for continuous definable functions on subsets locally closed in the $K$-topology and extending continuous hereditarily rational functions, established for the real and $p$-adic varieties in our joint paper with J. Kollár. The descent property enables application of resolution of singularities and transformation to a normal crossing by blowing up in much the same way as over the locally compact ground field. Our approach relies on quantifier elimination due to Pas and a concept of fiber shrinking for definable sets, which is a relaxed version of curve selection. The last three sections are devoted to the theory of regulous functions and sets over such valued fields. Regulous geometry over the real ground field $\mathbb{R}$ was developed by Fichou--Huisman--Mangolte--Monnier. The main results here are regulous versions of Nullstellensatz and Cartan's Theorems A and B.

(2009), Tibshirani (2014)], used for univariate nonparametric regression, to graphs. Analogous to the univariate case, graph trend filtering exhibits a level of local adaptivity unmatched by the usual $\ell_2$-based graph smoothers. It is also defined by a convex minimization problem that is readily solved (e.g., by fast ADMM or Newton algorithms). We demonstrate the merits of graph trend filtering through examples and theory.

Creators: name: Gering, Stefan
name: Adamy, Jürgen
Publisher: name: IFAC - International Federation of Automatic Control
Year: 2023

description: This paper presents an approach for stabilization of equilibria in recurrent fuzzy systems. This type of dynamic fuzzy systems being defined via linguistic rules can be interpreted as interpolation between constant gradients, and therefore as hybrid dynamical system. It is shown that the latter viewpoint allows for a precise description of the system dynamics, but on the other hand lacks transparency. In order to render a given equilibrium of the recurrent fuzzy system globally asymptotically stable, local polynomial controllers are computed via sum of squares optimization to allow only for deterministic mode transitions on a micro level. In addition, the controlled recurrent fuzzy system can then be interpreted as finite deterministic automaton, thus allowing for analysis of system properties on a more abstract macro level. Relaxations are proposed in cases where recurrent fuzzy systems may not be rendered deterministic and the method is applied to two examples.

description: Thermal stress response is an essential physiological trait that determines occurrence and temporal succession in nature, including response to climate change. We compared temperature-related demography in closely related heat-tolerant and heat-sensitive Brachionus rotifer species. We found significant differences in heat response, with the heat-sensitive species adopting a strategy of long survival and low population growth, while the heat-tolerant followed the opposite strategy. In both species, we examined the genetic basis of physiological variation by comparing gene expression across increasing temperatures. Comparative transcriptomic analyses identified shared and opposing responses to heat. Interestingly, expression of heat shock proteins (hsps) was strikingly different in the two species and mirrored differences in population growth rates, showing that hsp genes are likely a key component of a species’ adaptation to different temperatures. Temperature induction caused opposing patterns of expression in further functional categories including energy, carbohydrate and lipid metabolism, and in genes related to ribosomal proteins. In the heat-sensitive species, elevated temperatures caused up-regulation of genes related to meiosis induction and post-translational histone modifications. This work demonstrates the sweeping reorganizations of biological functions that accompany temperature adaptation in these two species and reveals potential molecular mechanisms that might be activated for adaptation to global warming.

description: Background Weight-related stigmatization is a widespread problem. Particularly the internalization of weight-related stereotypes and prejudices (weight bias internalization, WBI) is related to mental and physical health impairments. To date, little is known about the risk factors of WBI. Previous studies are mainly cross-sectional and based on adult samples. As childhood is a sensitive period for the development of a healthy self-concept, we examined predictors of WBI in children. Methods The final sample included 1,463 schoolchildren (6–11 years, 51.7% female) who took part in a prospective study consisting of three measurement waves. The first two waves delivered data on objective weight status and self-reported weight-related teasing, body dissatisfaction, relevance of one’s own figure, self-esteem and depressive symptoms; WBI was measured during the third wave. To examine predictors of WBI, we ran hierarchical regression analyses and exploratory mediation analyses. Results Lower parental education level, higher child weight status, female gender, experience of teasing, higher body dissatisfaction, higher figure-relevance, and higher depression scores were found to be predictive for higher WBI scores. Body dissatisfaction (only for girls) and the relevance of one’s own figure (both genders) mediated the association between self-esteem and WBI; no weight-related differences were observed. Conclusions Our study offers longitudinal evidence for variables that enable the identification of children who are at risk for WBI. Thus, the findings deliver starting points for interventions aimed at the prevention of adverse health developments that come along with WBI.

These sets ${\rm wt}_J \mathbb{V}^λ$ are defined for each highest weight module $\mathbb{V}^λ$ and each subset $J$ of simple roots; we term them "standard parabolic subsets of weights". It is shown that for any highest weight module, the sets of simple roots whose corresponding standard parabolic subsets of weights are equal form intervals in the poset of subsets of the set of simple roots under containment. Moreover, we provide closed-form expressions for the maximum and minimum elements of the aforementioned intervals for all highest weight modules $\mathbb{V}^λ$ over semisimple Lie algebras $\mathfrak{g}$. Surprisingly, these formulas only require the Dynkin diagram of $\mathfrak{g}$ and the integrability data of $\mathbb{V}^λ$. As a consequence, we extend classical work by Satake, Borel-Tits, Vinberg, and Casselman, as well as recent variants by Cellini-Marietti to all highest weight modules. We further compute the dimension, stabilizer, and vertex set of standard parabolic faces of highest weight modules, and show that they are completely determined by the aforementioned closed-form expressions. We also compute the $f$-polynomial and a minimal half-space representation of the convex hull of the set of weights. These results were recently shown for the adjoint representation of a simple Lie algebra, but analogues remain unknown for any other finite- or infinite-dimensional highest weight module. Our analysis is uniform and type-free, across all semisimple Lie algebras and for arbitrary highest weight modules.

description: A facile synthesis of novel 3-functionalized pyridine derivatives has been accomplished through the reaction of 4-hydroxy-3-benzoylpyridin-2(1H)-ones and β-nitrostyrenes in the presence of catalytic amount of pyrrolidine (10 mol%). In this process, the desired products were obtained with 72–87% yields using ethanol as solvent at 80 °C for 4 h. In addition, a total of 19 examples were obtained, which exhibited the broad substrate scope of the transformation. The reaction process may involve the formation of an unstable enamine intermediate and then undergo hydrolysis to afford 4-hydroxy-3-benzoylpyridin-2(1H)-one derivatives.
Comparison of metadata with relevance for bibliometrics between Microsoft Academic Graph and OpenAlex until 2020
Creators: name: Scheidsteger, Thomas
Publisher: name: Zenodo
Year: 2022

description: OpenAlex has transferred practically all works from MAG preserving their bibliographic data publication year, volume, first and last page, DOI as well as the number of references that are important ingredients of citation analysis. More than 90% of the MAG documents have equivalent document types in OpenAlex. Of the remaining ones, especially reclassifications to the OpenAlex document types journal-article and book-chapter seem to be valid and amount to more than 7%, so that the document type specifications have improved significantly from MAG to OpenAlex. So far, OpenAlex seems to be more suited for bibliometric analyses than MAG. As last item of bibliometric relevant metadata, we looked at the paper-based subject classification via FoS in MAG and in OpenAlex. We found significantly more documents with a FoS assignment in OpenAlex than in MAG. On the first and second level, the FoS structure is identical resp. nearly identical, but on the deeper levels the number of available FoSs is drastically reduced to about 10%. But this would not pose a problem if using only the upper two levels for bibliometric analyses as was done by Scheidsteger, et al. However, the reclassifications might cause changes to conclusions of previous studies. The consequences of the proliferation and abundant reclassification of top-level FoSs need to be studied more in detail. Reclassifications at the deeper levels should be studied, too. Overall, OpenAlex seems to be at least as suited for bibliometric analyses as MAG for publication years before 2021. However, this first impression needs to be checked by further detailed studies.

description: Recently the so-called Atiyah conjecture about l^2-Betti numbers has been disproved. The counterexamples were found using a specific method of computing the spectral measure of a matrix over a complex group ring. We show that in many situations the same method allows to compute homology gradients, i.e. generalizations of l^2-Betti numbers to fields of arbitrary characteristic. As an application we point out that (i) the homology gradient over any field of characteristic different than 2 can be an irrational number, and (ii) there exists a finite CW-complex with the property that the homology gradients of its universal cover taken over different fields have infinitely many different values.

A cut-off tubular geometry of loop space

description: Motivated by the computation of loop space quantum mechanics as indicated in [7], here we seek a better understanding of the tubular geometry of loop space ${\cal L}{\cal M}$ corresponding to a Riemannian manifold ${\cal M}$ around the submanifold of vanishing loops. Our approach is to first compute the tubular metric of $({\cal M}^{2N+1})_{C}$ around the diagonal submanifold, where $({\cal M}^N)_{C}$ is the Cartesian product of $N$ copies of ${\cal M}$ with a cyclic ordering. This gives an infinite sequence of tubular metrics such that the one relevant to ${\cal L}{\cal M}$ can be obtained by taking the limit $N\to \infty$. Such metrics are computed by adopting an indirect method where the general tubular expansion theorem of [12] is crucially used. We discuss how the complete reparametrization isometry of loop space arises in the large-$N$ limit and verify that the corresponding Killing equation is satisfied to all orders in tubular expansion. These tubular metrics can alternatively be interpreted as some natural Riemannian metrics on certain bundles of tangent spaces of ${\cal M}$ which, for ${\cal M} \times {\cal M}$, is the tangent bundle $T{\cal M}$.

title: Singleton-Based Two-String Inference in Recurrent Fuzzy Systems
Creators: name: Schneider, Moritz
name: Adamy, Jürgen
Publisher: name: IFAC - International Federation of Automatic Control
Year: 2023

description: Two-string fuzzy inference consists of two separate inference mechanisms: One conventional fuzzy inference system that processes recommending rules, as well as a mechanism for processing negative rules, which prevent the system from outputting their associated values when their premise is fulfilled. Two-string inference has valuable applications in pattern recognition and control tasks. We present a method rendering two-string inference applicable and computationally feasible in recurrent fuzzy systems, i.e. Mamdami-type fuzzy inference systems equipped with defuzzified state feedback. We show the efficiency of our approach by means of an illustrative example from biological systems modelling and suggest application areas for recurrent two-string fuzzy systems.
Afterpulsing model based on the quasi-continuous distribution of deep levels in single-photon avalanche diodes

description: We have performed a statistical characterization of the effect of afterpulsing in a free-running silicon single-photon detector by measuring the distribution of afterpulse waiting times in response to pulsed illumination and fitting it by a sum of exponentials. We show that a high degree of goodness of fit can be obtained for 5 exponentials, but the physical meaning of estimated characteristic times is dubious. We show that a continuous limit of the sum of exponentials with a uniform density between the limiting times gives excellent fitting results in the full range of the detector response function. This means that in certain detectors the afterpulsing is caused by a continuous band of deep levels in the active area of the photodetector.

title: Synchronizing Linear Heterogeneous Networks by Output Homogenization

Publisher: name: IFAC - International Federation of Automatic Control

description: This article deals with the synchronization of heterogeneous multi-agent systems. A simple distributed control law is provided to solve the problem. The presented approach is based on the idea to ascribe the heterogeneous case to a homogeneous synchronization task, for which the solution is well known. The presented method is applicable to networks of completely different agents, even with different dimensions. Additionally, the communication effort is minimized because only the states which are to be synchronized need to be exchanged through the network. An example illustrates the efficiency of the concept.
