title: A new Pattern for Quantum Evolutionary Algorithms

description: Quantum Evolutionary Algorithms have been discussed in the literature in different forms. One branch in these efforts studies approaches for the representation of genetic information, i.e., problem information, in terms of qubits. A typical downside of this representation has been the loss of quantum information in the evaluation and selection steps of the algorithm. I.e., algorithms are implemented in a hybrid-classical setup and require measurements in each iteration. This inevitably destroys superpositions and entanglement structures in the genome representation. In this work, we propose a new implementation approach for genetic information and the evaluation and selection phase, which realizes those steps within the quantum circuit. To achieve this, we utilize qudits for representing the evolving entities. Additionally, we make use of patterns for the design of quantum sub-circuits to compose control structures known from the classical realm. As a result, we show a quantum circuit design for anytime algorithms that does not have to be measured in every iteration and that does not depend on classical control. The overall progress of the evolutionary process only needs to be checked occasionally on a flag-qubit. The approach currently comes with some limitations e.g., in the objective function. It is presented here for the toy problem Leading Ones.

description: Die Möglichkeiten für Cyberkriminelle, Straftaten im Internet anonym zu begehen, haben mit der Entwicklung von Darknet-Technologien erheblich zugenommen. Zur Aufklärung dieser Straftaten kommt aus technischer Perspektive die Nutzung von Open Source Intelligence (OSINT) in Betracht. Diese Methode bezeichnet einen Vorgang, bei dem Daten aus öffentlich zugänglichen Quellen gesammelt werden, um durch deren Auswertung an ermittlungsrelevante Erkenntnisse zu gelangen. Der folgende Beitrag thematisiert die Nutzung von OSINT zur Strafverfolgung im Darknet und wirft die Frage auf, was nach dem aktuellen Stand der Technik möglich und was auf Grundlage der geltenden strafprozessualen Vorgaben rechtlich zulässig ist. Die Verfasser*innen kommen zu dem Ergebnis, dass ein legislatives „Update“ der StPO unvermeidbar sein wird, wenn die rechtlichen Vorgaben mit den technischen Möglichkeiten Schritt halten sollen. Dieses Ergebnis wird damit begründet, dass die Nutzung von OSINT aufgrund ihrer grundrechtlichen Eingriffsintensität in vielen Fällen nicht mehr auf die Ermittlungsgeneralklausel der §§ 161, 163 StPO gestützt werden kann.

description: We construct Hadamard states for Klein-Gordon fields in a spacetime $M_{0}$ equal to the interior of the future lightcone $C$ from a base point $p$ in a globally hyperbolic spacetime $(M, g)$. Under some regularity conditions at future infinity of $C$, we identify a boundary symplectic space of functions on $C$, which allows to construct states for Klein-Gordon quantum fields in $M_{0}$ from states on the CCR algebra associated to the boundary symplectic space. We formulate the natural microlocal condition on the boundary state on $C$ ensuring that the bulk state it induces in $M_{0}$ satisfies the Hadamard condition. Using pseudodifferential calculus on the cone $C$ we construct a large class of Hadamard boundary states on the boundary with pseudodifferential covariances, and characterize the pure states among them. We then show that these pure boundary states induce pure Hadamard states in $M_{0}$.

description: The Digital Product Passport (DPP) is a concept to collect and share product-related information along a product's lifecycle. The aim is to provide all stakeholders during the product lifecycle with the information they need such that a successful Circular Economy can be implemented. At the moment, several varieties of DPPs are being developed, most of them sector-specific. As of today, however, there is no common standard as to what a DPP should look like. This paper collects requirements for the DPP from different perspectives that must be fulfilled to make it broadly applicable.

description: Proton‐responsive photochromic molecules are attractive for their ability to react on non‐invasive rapid optical stimuli and the importance of protonation/deprotonation processes in various fields. Conventionally, their acidic/basic sites are on hetero‐atoms, which are orthogonal to the photo‐active π‐center. Here, we incorporate azulene, an acid‐sensitive pure hydrocarbon, into the skeleton of a diarylethene‐type photoswitch. The latter exhibits a novel proton‐gated negative photochromic ring‐closure and its optical response upon protonation in both open and closed forms is much more pronounced than those of diarylethene photoswitches with hetero‐atom based acidic/basic moieties. The unique behavior of the new photoswitch can be attributed to direct protonation on its π‐system, supported by 1H NMR and theoretical calculations. Our results demonstrate the great potential of integrating non‐alternant hydrocarbons into photochromic systems for the development of multi‐responsive molecular switches.

description: For $x>0$ let $π(x)$ denote the number of primes not exceeding $x$. For integers $a$ and $m>0$, we determine when there is an integer $n>1$ with $π(n)=(n+a)/m$. In particular, we show that for any integers $m>2$ and $a\le\lceil e^{m-1}/(m-1)\rceil$ there is an integer $n>1$ with $π(n)=(n+a)/m$. Consequently, for any integer $m>4$ there is a positive integer $n$ with $π(mn)=m+n$. We also pose several conjectures for further research; for example, we conjecture that for each $m=1,2,3,\ldots$ there is a positive integer $n$ such that $m+n$ divides $p_m+p_n$, where $p_k$ denotes the $k$-th prime.

The You Yangs batholith in Southeastern Australia, the sources of its magmas and inferences for local crustal architecture

description: The 365-Ma You Yangs batholith is a mainly I-type monzogranitic body, containing rocks with both clinopyroxene and hornblende, but with a 2–2.5 km-wide rim of S-type rocks. In places, the margins of the intrusion wedge out laterally. A laccolithic shape may explain there being only low-grade contact metamorphism of the Ordovician metasedimentary wall rocks. The chemical and isotopic characteristics of the granitic rocks suggest that the magmas formed by partial melting of a source that contained some meta-igneous rocks but was dominated by chemically immature metasedimentary types, to impart an evolved Sr isotope signature (87Sr/86Srt = 0.70877–0.71066 for the main monzogranitic rocks), combined with relatively non-radiogenic εNdt (–2.4 to –1.9). Crystal fractionation played little role in shaping the compositions of the granitic magmas, with the main variations interpreted to be source-inherited. Igneous-textured microgranular enclaves (IMEs) are prominent in the monzogranitic rocks. The IMEs probably had an ultimate enriched-mantle source, and their magmas did not mix significantly with the crustally derived granitic host magmas. The characteristics of the monzogranitic rocks hosting the enclaves suggest the possibility that an unrecognised metasediment-dominated terrane of ancient arc crust may be present beneath the Bendigo Zone.

description: Non-locality is the phenomenon of observing strong correlations among the outcomes of local measurements of a multipartite physical system. No-signaling boxes are the abstract objects for studying non-locality, and wirings are local operations on the space of no-signaling boxes. This means that, no matter how non-local the nature is, the set of physical non-local correlations must be closed under wirings. Then, one approach to identify the non-locality of nature is to characterize closed sets of non-local correlations. Although non-trivial examples of wirings of no-signaling boxes are known, there is no systematic way to study wirings. In particular, given a set of no-signaling boxes, we do not know a general method to prove that it is closed under wirings. In this paper, we propose the first general method to construct such closed sets of non-local correlations. We show that a well-known measure of correlation, called maximal correlation, when appropriately defined for non-local correlations, is monotonically decreasing under wirings. This establishes a conjecture about the impossibility of simulating isotropic boxes from each other, implying the existence of a continuum of closed sets of non-local boxes under wirings. To prove our main result, we introduce some mathematical tools that may be of independent interest: we define a notion of maximal correlation ribbon as a generalization of maximal correlation, and provide a connection between it and a known object called hypercontractivity ribbon; we show that these two ribbons are monotone under wirings too.

description: The goal of this article is to deepen our understanding of geographical differences in the ability to attract funding from the European Union’s Framework Programs for Research and Innovation (EU FPs), by changing focus from country to a) the regional (NUTS-2) and b) sectorial level of Europe, where we explore variations between regions’ three main R&D sectors: higher education, business, and government. The study covers 57,795 EU funded projects from 2007 to 2020, showing that within each country, there are large difference in attractiveness between regions, and that within each region there are remarkable differences in comparative attractiveness of different sectors. Moreover, we observe a tendency of increasing divergence between regions in their level of EU FP funding attraction.

Dynamics and stability of a discrete breather in a harmonically excited chain with vibro-impact on-site potential

description: We investigate the existence and stability of discrete breathers in a chain of masses connected by linear springs and subjected to vibro-impact on-site potentials. The latter are comprised of harmonic springs and rigid constraints limiting the possible motion of the masses. Local dissipation is introduced through a non-unit restitution coefficient characterizing the impacts. The system is excited by uniform time-periodic forcing. The present work is aimed to study the existence and stability of similar breathers in the space of parameters, if additional harmonic potentials are introduced. Existence-stability patterns of the breathers in the parameter space and possible bifurcation scenarios are investigated analytically and numerically. In particular, it is shown that the addition of harmonic on-site potential can substantially extend the stability domain, at least close to the anti-continuum limit. This result can be treated as an increase in the robustness of the breather from the perspective of possible practical applications.

description: Open Data impliziert die freie Zugänglichkeit, Verfügbarkeit und Wiederverwendbarkeit von Datensätzen. Obwohl hochwertige Datensätze öffentlich verfügbar sind, ist der Zugang zu diesen und die Transparenz über die Formate nicht immer gegeben. Dies mindert die optimale Nutzung des Potenzials zur Wertschöpfung, trotz der vorherrschenden Einigkeit über ihre Chancen. Denn Open Data ermöglicht das Vorantreiben von Compliance-Themen wie Transparenz und Rechenschaftspflicht bis hin zur Förderung von Innovationen. Die Nutzung von Open Data erfordert Mut und eine gemeinsame Anstrengung verschiedener Akteure und Branchen. Im Rahmen des vorliegenden Beitrags werden auf Grundlage des Design Science-Ansatzes eine Open Data Capability Map sowie darauf aufbauend eine Datenarchitektur für Open Data in der Luftfahrtindustrie an einem Beispiel entwickelt.

description: In this Article, we assess to what extent art. 9 TFEU, which contains the social mainstreaming clause, may be used to shore up the social dimension of the EU Single Market. The story of hope of a more socially inclusive internal market starts with the "porous" EU internal market legal framework itself and ends with art. 153 TFEU and the European Pillar of Social Rights. Yet, there are also fears that, despite the language of social mainstreaming, the EU cannot deliver on the promise of art. 9 TFEU for various reasons, including the limited legislative competences of the EU to pursue social policies. While we mainly want to emphasize the story of hope, we will also look into the fears and how some of these could be addressed.

description: We give an explicit relation, up to second-order terms, between scalar-field fluctuations defined on spatially-flat slices and the curvature perturbation on uniform-density slices. This expression is a necessary ingredient for calculating observable quantities at second-order and beyond in multiple-field inflation. We show that traditional cosmological perturbation theory and the `separate universe' approach yield equivalent expressions for superhorizon wavenumbers, and in particular that all nonlocal terms can be eliminated from the perturbation-theory expressions.

description: We consider a strongly coupled system of partial differential equations as a model for the dynamics of a thermo-visco-elasto-plastic solid under phase transitions. It consists of the momentum balance equation for the displacement, the energy balance equation for the absolute temperature, and an order parameter equation describing the dynamics of the phase transition. Both the phase transition and the strain-stress law involve hysteresis dependence represented by hysteresis operators. We show the thermodynamic consistency of the model, and prove its well-posedness.

description: With the couplings between the eight gluons constrained by the structure constants of the su(3) algebra in QCD, one would expect that there should exist a special basis (or set of bases) for the algebra wherein, unlike in a Cartan-Weyl basis, {\em all} gluons interact identically (cyclically) with each other, explicitly on an equal footing. We report here particular such bases, which we have found in a computer search, and we indicate associated $3 \times 3$ representations. We conjecture that essentially all cyclic bases for su(3) may be obtained from these making appropriate circulant transformations,and that cyclic bases may also exist for other su(n), n>3.

As an example, for $\mathbb{C}^{12n}\bigotimes\mathbb{C}^{12n}$ systems, we show that there are at least two sets of UMEBs which are not equivalent.

description: Die Erfahrungen der letzten Jahre im Bereich Data Science zeigen immer deutlicher, dass es ein Umdenken bei der Ausbildung bedarf, da die sozialen Nuancen in Daten nicht erfasst oder ethische Kriterien bei der Entwicklung datengetriebener Software zu selten berücksichtigt werden. Diese Lücke soll mit dem Ansatz der Human-Centered Data Science geschlossen werden. Im Rahmen einer Lehrveranstaltung mit Informatikstudierenden haben wir daher diesen Ansatz umgesetzt. Die Ergebnisse einer im Anschluss durchgeführten Interviewstudie zeigen, dass Studierende ein gesteigertes Bewusstsein für die gesellschaftlichen Auswirkungen von Data Science haben. Nichtsdestotrotz hatten wir jedoch den Eindruck, dass sie nicht über eine „Toolbox“ verfügen, die es ihnen erlaubt, diese Einsicht nachhaltig in ihren Datenpraktiken zu verankern. Infolgedessen schlagen wir einen konzeptionellen Rahmen für die Förderung einer kritisch-reflexiven Praxis in der Data Science-Ausbildung vor, den wir in diesem Artikel näher vorstellen. Anhand einer beispielhaften Umsetzung erläutern wir jede der vier aufeinander aufbauenden Phasen, die in zukünftiger Forschung evaluiert werden.

Intell. pp. 1--26 (2013)) in which they study the computational complexity of bribery schemes when voters have conditional preferences that are modeled by CP-nets. For most of the cases they considered, they could show that the bribery problem is solvable in polynomial time. Some cases remained open---we solve two of them and extend the previous results to the case that voters are weighted. Moreover, we consider negative (weighted) bribery in CP-nets, when the briber is not allowed to pay voters to vote for his preferred candidate.

description: This paper re-examines the relationship between per capita income, inequality, and per capita emissions while accounting for nonhomotheticity in green preferences and nonlinearities in the impact of economic growth on GHG emissions. Theoretically, our research is motivated by the fact that if environmental quality is a need with low priority on the hierarchical scale, the effect of inequality on emissions should vary depending on the level of income per capita. Specifically, for a given level of income per capita, a richer median voter will be more likely to approve of more stringent environmental policies, and thus, lower inequality is beneficial for the environment. With nonhomothetic preferences, the beneficial environmental effect of reducing inequality emerges only for countries that are sufficiently rich. We test this hypothesis by augmenting a standard EKC equation with the interaction between income per capita and the Gini coefficient. Our results for CO2, SO2 and N2O emissions corroborate our main hypothesis: reducing inequality is beneficial for the environment only for rich countries.

description: We introduce our approach for incremental truth inference over the contributions provided by players of Games with a Purpose: we motivate the need for such a method with the specificity of GWAP vs. traditional crowdsourcing; we explain and formalize the proposed process and we explain its positive consequences; finally, we illustrate the results of an experimental comparison with state-of-the-art approaches, performed on data collected through two different GWAPs, thus showing the properties of our proposed framework.
Convergence of functions of self-adjoint operators and applications
Creators: name: Brown, Lawrence G.
Publisher: name: arXiv

Subjects: subject: Functional Analysis (math.FA)
subject: FOS: Mathematics

description: The main result (roughly) is that if (H_i) converges weakly to H and if also f(H_i) converges weakly to f(H), for a single strictly convex continuous function f, then (H_i) must converge strongly to H. One application is that if f(pr(H)) = pr(f(H)), where pr denotes compression to a closed subspace M, then M must be invariant for H. A consequence of this is the verification of a conjecture of Arveson, that Theorem 9.4 of [Arv] remains true in the infinite dimensional case. And there are two applications to operator algebras. If h and f(h) are both quasimultipliers, then h must be a multiplier. Also (still roughly stated) if h and f(h) are both in pA_sa p, for a closed projection p, then h must be strongly q-continuous on p.
description: This paper is intended for a dual audience. Section 2, which contains the main result, is suitable for a general audience. Section 3 concerns technical operat or algebraic questions, though I have tried to present it with a minimum of tech nicality. As with all my papers, I welcome comments, especially for this paper, since I know almost nothing about Korovkin type theorems

description: Based on the analogies between knot theory and number theory, we study a deformation theory for SL_2-representations of knot groups, following after Mazur's deformation theory of Galois representations. Firstly, by employing the pseudo-SL_2-representations, we prove the existence of the universal deformation of a given SL_2-representation of a finitely generated group Pi over a field whose characteristic is not 2. We then show its connection with the character scheme for SL_2-representations of Pi when k is an algebraically closed field. We investigate examples concerning Riley representations of 2-bridge knot groups and give explicit forms of the universal deformations. Finally we discuss the universal deformation of the holonomy representation of a hyperbolic knot group in connection with Thurston's theory on deformations of hyperbolic structures.

description: Kirwan identified a condition on a smooth function under which the usual techniques of Morse-Bott theory can be applied to this function. We prove that if a function satisfies this condition locally then it also satisfies the condition globally. As an application, we use the local normal form theorem to recover Kirwan's result that the norm-square of a momentum map satisfies Kirwan's condition.

description: We introduce a collection of convex polytopes associated to a torus-equivariant vector bundle on a smooth complete toric variety. We show that the lattice points in these polytopes correspond to generators for the space of global sections and we relate edges to jets. Using the polytopes, we also exhibit toric vector bundles that are ample but not globally generated, and toric vector bundles that are ample and globally generated but not very ample.

description: We consider superfluidity and quantum vorticity in rotating spacetimes. The system is described by a complex scalar satisfying a nonlinear Klein-Gordon equation. Rotation terms are identified and found to lead to the transfer of angular momentum of the spacetime to the scalar field. The scalar field responds by rotating, physically behaving as a superfluid, through the creation of quantized vortices. We demonstrate the vortex nucleation through numerical simulation.

A Study of Snake-like Locomotion Through the Analysis of a Flexible Robot Model

description: We examine the problem of snake-like locomotion by studying a system consisting of a planar inextensible elastic rod that is able to control its spontaneous curvature. Using a Cosserat model we derive, through variational principles, the equations of motion for two special cases: one in which the system is confined inside a frictionless channel, and one in which it is placed in an anisotropic frictional environment, modeling the dynamical setting of the slithering of snakes on flat surfaces. The presence of constraints in both cases leads to non-standard boundary conditions, that allow us to close the equations of motion reducing them to a differential and an integro-differential equation, respectively, for one end point (the tail) of the active rod. For the snake-like case we also provide analytic solutions for a special class of motions. We highlight the role of the spontaneous curvature in the pushing (and the steering, in the snake-like setting) needed to power locomotion. Comparisons with available experiments confirm that the model is able to capture many of the essential findings in the zoological literature. The complete solvability and the existence of analytic solutions offers a tool that may prove valuable for the design of bio-inspired soft robots.
