description: The COVID-19 pandemic has shown companies that their on-premise infrastructures often reach their limits with a large number of remote accesses. The transition to cloud-based solutions could represent a more efficient alternative. However, many German companies, especially small and medium-sized enterprises (SME), are still hesitant to take this big step of transferring applications to the cloud. For this reason, this paper examines the question of whether existing migration approaches in the analysis phase fit the specific requirements of SMEs. Using a literature review methodology, we first identify and analyze determinant factors for cloud adoption in SMEs. On this basis, we analyze existing methods in the analysis phase for migrations from on-premise software to cloud solutions. We investigate whether these factors are considered in the analysis phase of the approaches and conclude their suitability for SMEs. Of the migration approaches we examined, none included all the factors we identified as relevant to SMEs. Fewer have considered all factors fully and in detail. We present the results of the literature search process in tabular form and conclude this paper with a discussion and synthesis of the literature as well as an outlook on further research fields.

description: In this paper, I present a review of the main results obtained in the last 10 years in the field of radio-detection of cosmic-ray air showers in the MHz range. All results from all experiments cannot be reported here so that I will focus on the results more than on the experiments themselves. Modern experiments started in 2003 with CODALEMA and LOPES. In 2006, small-size autonomous prototypes setup were installed at the Pierre Auger Observatory site, to help the design of the Auger Engineering Radio Array (AERA). We will discuss the principal aspects of the radio data analysis and the determination of the primary cosmic ray characteristics: the arrival direction, the lateral distribution of the electric field, the correlation with the primary energy, the emission mechanisms and the sensitivity to the composition of the cosmic rays.

description: Recent advances in Artificial Intelligence extend the boundaries of what machines can do in all industries and business sectors. The economic potential to apply AI in manufacturing results in an increasing number of companies striving to gain a competitive advantage through AI and move into new markets. In this context, particular importance is given to the predictive maintenance of machines. Predictive maintenance promises the possibility of avoiding unexpected machine downtimes and thus increasing the availability of production lines. However, only a few machine manufacturers have a marketable offering of AI-based products or services in their portfolio. Even if technical feasibility is proven, companies lack an understanding of how to integrate AI solutions into new Business Models. This paper thus presents three case studies and their Business Models as examples. Practical considerations and recommendations on the strategical adoption of predictive maintenance technologies are derived.

description: We consider a two-mode atomic Josephson junction realized with dilute dipolar bosons confined by a double-well. We employ the two-site extended Bose-Hubbard Hamiltonian and characterize the ground-state of this system by the Fisher information, coherence visibility, and entanglement entropy. These quantities are studied as functions of the interaction between bosons in different wells. The emergence of Schroedinger-cat like state with a loss of coherence is also commented.

Requirements for Human-Centric Informational Complexity Management in Production in the Context of the Matrix Fusion Factory

description: For four years now, the concept of the Matrix Fusion Factory MFF has been developed and studied. The MFF dissolves the separation between digital and real entities and focuses on value creation in production. The MFF is based on two prerequisites: first, an organizational structure for assessing value creation in factories whose modular hardware and software structures are constantly reconfigured; and second, the fragmentation logic presupposes increasing complexity, which in turn requires methods for evaluating and reducing complexity. This paper focuses on the reduction and management of informational complexity since different ways of information management (i.e. capturing, selecting, compressing, and providing information) lead to different effects on the production system, especially if the information is processed by humans. Therefore, the central assessment approach for information management must be value creation. Thus, this paper discusses the impact of information management on value creation and how information management can support value creation. In particular, it is clarified how informational complexity in production can be reduced without distorting the underlying information and the implications for technology and organization are discussed.
Density Perturbations from Modulated Decay of the Curvaton

description: We study density perturbations, including their non-Gaussianity, in models in which the decay rate of the curvaton depends on another light scalar field, denoted the modulaton. Although this model shares some similarities with the standard curvaton and modulated reheating scenarios, it exhibits interesting predictions for f_NL and g_NL that are specific to this model. We also discuss the possibility that both modulaton and curvaton fluctuations contribute to the final curvature perturbation. Our results naturally include the standard curvaton and modulated reheating scenarios as specific limits and are thus useful to present a unified treatment of these models and their variants.

description: We have investigated the pattern formation in systems described by the nonlocal Fisher--Kolmogorov--Petrovskii--Piskunov equation for the cases where the dimension of the pattern concentration area is less than that of independent variables space. We have obtained a system of integro-differential equations which describe the dynamics of the concentration area and the semiclassically limited distribution of a pattern in the class of trajectory concentrated functions. Also, asymptotic large-time solutions have been obtained that describe the semiclassically limited distribution of a quasi-steady-state pattern on the concentration manifold. The approach is illustrated by an example for which the analytical solution is in good agreement with the prediction of a numerical simulation.

description: The system-environment interaction is simulated by light propagating in coupled photonic waveguides. The profile of the electromagnetic field provides intuitive physical insight to study the Markovian and non-Markovian dynamics of open quantum systems. The transition from non-Markovian to Markovian process is demonstrated by increasing the size of environment, as the energy evolution changes from oscillating to an exponential decay, and the revival period increases. Moreover, the dynamical decoupling with a sequence of phase modulations is introduced to such a photonic open system to form a band structure in time dimension, where the energy dissipation can be significantly accelerated or inhibited. It opens the possibility to tune the dissipation in photonic system, similar to the dynamic decoupling of spins.

We give the Levi-Civita connections and explicit formulas for computing sectional curvatures of these metrics and show that all these spaces have constant scalar curvature. We also show that they are flat or they have only non-negative or non-positive sectional curvature.

description: A quantum system whose internal Hamiltonian is not strongly regular or/and control Hamiltonians are not full connected, are thought to be in the degenerate cases. In this paper, convergence problems of the multi-control Hamiltonians closed quantum systems in the degenerate cases are solved by introducing implicit function perturbations and choosing an implicit Lyapunov function based on the average value of an imaginary mechanical quantity. For the diagonal and non-diagonal tar-get states, respectively, control laws are designed. The convergence of the control system is proved, and an explicit design principle of the imaginary mechanical quantity is proposed. By using the proposed method, the multi-control Hamiltonians closed quantum systems in the degenerate cases can converge from any initial state to an arbitrary target state unitarily equivalent to the initial state. Finally, numerical simulations are studied to verify the effectiveness of the proposed control method.

description: In this paper we aim to prove two inequalities involving the classical approximation constants $w_{n}^{\prime}(ζ),\hat{w}_{n}^{\prime}(ζ)$ that stem from the simultaneous approximation problem $|ζ^{j}x-y_{j}|$, $1\leq j\leq n$, on the one side and the constants $w_{n}^{\ast}(ζ),\hat{w}_{n}^{\ast}(ζ)$ connected to approximation with algebraic numbers of degree $\leq n$ on the other side. We concretely prove $w_{n}^{\ast}(ζ)\hat{w}_{n}^{\prime}(ζ)\geq 1$ and $\hat{w}_{n}^{\ast}(ζ)w_{n}^{\prime}(ζ)\geq 1$. The first result is due to W. Schmidt, however our method of proving it allows to derive the other inequality as a dual result. Finally we will discuss estimates of $w_{n}^{\ast}(ζ), \hat{w}_{n}^{\ast}(ζ)$ uniformly in $ζ$ depending only on $n$ as an application.

Slight compressibility and sensitivity to changes in Poisson's ratio

description: Finite Element simulations of rubbers and biological soft tissue usually assume that the material being deformed is slightly compressible. It is shown here that in shearing deformations the corresponding normal stress distribution can exhibit extreme sensitivity to changes in Poisson's ratio. These changes can even lead to a reversal of the usual Poynting effect. Therefore the usual practice of arbitrarily choosing a value of Poisson's ratio when numerically modelling rubbers and soft tissue will, almost certainly, lead to a significant difference between the simulated and actual normal stresses in a sheared block because of the difference between the assumed and actual value of Poisson's ratio. The worrying conclusion is that simulations based on arbitrarily specifying Poisson's ratio close to 1/2 cannot accurately predict the normal stress distribution even for the simplest of shearing deformations. It is shown analytically that this sensitivity is due to the small volume changes which inevitably accompany all deformations of rubber-like materials. To minimise these effects, great care should be exercised to accurately determine Poisson's ratio before simulations begin.

Although there are those literary critics who assert that a poem should be read entirely out of the context, there is much to be gained by looking at the poem with the additional background information about the author, particularly what the primary influences of the author are. Such is the intent with this essay in providing a behind-the-scenes look at what shaped and created the Golliwogg collection.

Convergence rate of Markov chain methods for genomic motif discovery
Creators: name: Woodard, Dawn B.

Publisher: name: arXiv
Year: 2013
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: We analyze the convergence rate of a simplified version of a popular Gibbs sampling method used for statistical discovery of gene regulatory binding motifs in DNA sequences. This sampler satisfies a very strong form of ergodicity (uniform). However, we show that, due to multimodality of the posterior distribution, the rate of convergence often decreases exponentially as a function of the length of the DNA sequence. Specifically, we show that this occurs whenever there is more than one true repeating pattern in the data. In practice there are typically multiple such patterns in biological data, the goal being to detect the most well-conserved and frequently-occurring of these. Our findings match empirical results, in which the motif-discovery Gibbs sampler has exhibited such poor convergence that it is used only for finding modes of the posterior distribution (candidate motifs) rather than for obtaining samples from that distribution. Ours are some of the first meaningful bounds on the convergence rate of a Markov chain method for sampling from a multimodal posterior distribution, as a function of statistical quantities like the number of observations.

description: A test can be defined as an orchestrated attempt to reveal an entity's potentially unknown properties or capacities. There are stress tests and screen tests, personality tests and citizenship tests, tests of strength and tests of faith. Tests have become such a familiar genre that today it seems almost anything can be a test situation. The challenge that a new sociology of testing must address is that ubiquitous testing changes the relations between science, engineering and sociology: Engineering is today in the very stuff of where society happens. It is not that the tests of 21st Century engineering occur within a social context but that it is the very fabric of the social that is being put to the test.

description: Durch die Migrationsbewegungen der letzten Jahrzehnte hat sich der Anteil junger Menschen mit eigener Migrationserfahrung im schulpflichtigen Alter in Deutschland erhöht. Um diesen Schüler*innen eine gerechte und erfolgreiche Bildungsteilhabe zu ermöglichen, bedarf es evidenzbasierter Maßnahmen. Dabei ist es u.a. essenziell, Forschungsergebnisse zu sprachlichen und fachlichen Kompetenzen der Schüler*innen sowie ihrer Entwicklung zu berücksichtigen. In Form eines Scoping Reviews widmet sich der vorliegende Beitrag der Erstellung und Präsentation einer systematischen Überblicksdarstellung der im deutschsprachigen Raum vorliegenden Forschungsarbeiten. Die Ergebnisse der einschlägigen Studien zeigen u.a. eine starke Heterogenität innerhalb der Gruppe und Bestätigen die Notwendigkeit durchgängiger sprachlicher Bildung. Insgesamt lässt sich festhalten, dass dieser Bereich wenig erforscht ist und es weiterer Studien bedarf.

description: The small mission A-STAR (All-Sky Transient Astrophysics Reporter) aims to locate the X-ray counterparts to ALIGO and other gravitational wave detector sources, to study the poorly-understood low luminosity gamma-ray bursts, and to find a wide variety of transient high-energy source types, A-STAR will survey the entire available sky twice per 24 hours. The payload consists of a coded mask instrument, Owl, operating in the novel low energy band 4-150 keV, and a sensitive wide-field focussing soft X-ray instrument, Lobster, working over 0.15-5 keV. A-STAR will trigger on ~100 GRBs/yr, rapidly distributing their locations.

description: We show that the European airspace can be represented as a multi-scale traffic network whose nodes are airports, sectors, or navigation points and links are defined and weighted according to the traffic of flights between the nodes. By using a unique database of the air traffic in the European airspace, we investigate the architecture of these networks with a special emphasis on their community structure. We propose that unsupervised network community detection algorithms can be used to monitor the current use of the airspaces and improve it by guiding the design of new ones. Specifically, we compare the performance of three community detection algorithms, also by using a null model which takes into account the spatial distance between nodes, and we discuss their ability to find communities that could be used to define new control units of the airspace.

Hodge-Newton Filtration for $p$-Divisible Groups with Ramified Endomorphism Structure
Creators: name: Marrama, Andrea
Publisher: name: Deutsche Mathematiker-Vereinigung
Year: 2022

description: Let $\mathcal{O}_K$ be a complete discrete valuation ring of mixed characteristic $(0,p)$ with perfect residue field. We prove the existence of the Hodge-Newton filtration for $p$-divisible groups over $\mathcal{O}_K$ with additional endomorphism structure for the ring of integers of a finite, possibly ramified field extension of $\mathbb{Q}_p$. The argument is based on the Harder-Narasimhan theory for finite flat group schemes over $\mathcal{O}_K$. In particular, we describe a sufficient condition for the existence of a filtration of $p$-divisible groups over $\mathcal{O}_K$ associated to a break point of the Harder-Narasimhan polygon.

Strong Purifying Selection at Synonymous Sites in D. melanogaster

description: Synonymous sites are generally assumed to be subject to weak selective constraint. For this reason, they are often neglected as a possible source of important functional variation. We use site frequency spectra from deep population sequencing data to show that, contrary to this expectation, 22% of four-fold synonymous (4D) sites in D. melanogaster evolve under very strong selective constraint while few, if any, appear to be under weak constraint. Linking polymorphism with divergence data, we further find that the fraction of synonymous sites exposed to strong purifying selection is higher for those positions that show slower evolution on the Drosophila phylogeny. The function underlying the inferred strong constraint appears to be separate from splicing enhancers, nucleosome positioning, and the translational optimization generating canonical codon bias. The fraction of synonymous sites under strong constraint within a gene correlates well with gene expression, particularly in the mid-late embryo, pupae, and adult developmental stages. Genes enriched in strongly constrained synonymous sites tend to be particularly functionally important and are often involved in key developmental pathways. Given that the observed widespread constraint acting on synonymous sites is likely not limited to Drosophila, the role of synonymous sites in genetic disease and adaptation should be reevaluated.

description: In recent years, the automated digital capture of traffic infrastructure has gained importance. Apart from large-scale map providers, also automotive manufacturers and traffic infrastructure providers rely on digital spatial information for different purposes. There are two main drivers for this field of research: the need for precise spatial digital twins to enable simulation and driving functions, especially for autonomous mobility the need for predictive maintenance and asset management of infrastructure.
A Tutorial on the Optimization of Amplify-and-Forward MIMO Relay Systems

description: The remarkable promise of multiple-input multiple-output (MIMO) wireless channels has motivated an intense research activity to characterize the theoretical and practical issues associated with the design of transmit (source) and receive (destination) processing matrices under different operating conditions. This activity was primarily focused on point-to-point (single-hop) communications but more recently there has been an extensive work on two-hop or multi-hop settings in which single or multiple relays are used to deliver the information from the source to the destination. The aim of this tutorial is to provide an up-to-date overview of the fundamental results and practical implementation issues of designing amplify-and-forward MIMO relay systems.

description: In this paper we study flag curvature of invariant $(α,β)$-metrics of the form $\frac{(α+β)^2}α$ on homogeneous spaces and Lie groups. We give a formula for flag curvature of invariant metrics of the form $F=\frac{(α+β)^2}α$ such that $α$ is induced by an invariant Riemannian metric $g$ on the homogeneous space and the Chern connection of $F$ coincides to the Levi-Civita connection of $g$. Then some conclusions in the cases of naturally reductive homogeneous spaces and Lie groups are given.

description: We have successfully grown the single crystal of a low carrier density system Y$_3$Ru$_4$Ge$_{13}$ which crystallizes in the cubic crystal structure with the space group Pm3n. Y$_3$Ru$_4$Ge$_{13}$ exhibits super conductivity below 2.85 K as determined from the electrical resistivity, magnetic susceptibility and heat capacity measurements. The bulk measurements indicate multiband superconductivity in this low carrier system. Hall effect measurements show that the Hall coefficient R$_H$ is positive and it decreases rapidly with temperature which is highly unusual. The simple estimation of the carrier concentration gives a value (\sim 10$^{20}$/cm$^3$) which is 2-3 orders of magnitude lower than that of a conventional metal like Cu which seems to suggest that Y$_3$Ru$_4$Ge$_{13}$ is a semimetal that display multiband superconductivity.

description: In a one-dimensional spinless p-wave superconductor with coherence length ξ, disorder induces a phase transition between a topologically nontrivial phase and a trivial insulating phase at the critical mean free path l=ξ/2. Here, we show that a multichannel spinless p-wave superconductor goes through an alternation of topologically trivial and nontrivial phases upon increasing the disorder strength, the number of phase transitions being equal to the channel number N. The last phase transition, from a nontrivial phase into the trivial phase, takes place at a mean free path l = ξ/(N+1), parametrically smaller than the critical mean free path in one dimension. Our result is valid in the limit that the wire width W is much smaller than the superconducting coherence length ξ.
