description: Es wurden in drei deutschen Regionen Interviews mit Gründern über 50 Jahren durchgeführt. Die Daten dieser Regionen ergaben einen Überblick über die typischen deutschen Wirtschaftsstrukturen (Agrar- Industrie- und Dienstleistungssektor). Die Perspektive des Bankensektors, die Perspektive des Beratungssektors und die Perspektive der Seniorengründer selbst sind evaluiert worden. In den Interviews wurden Risikoneigung, Finanzierungsprobleme, Motivation, Selbstverwirklichung, Zeitmanagement, Hindernisse bei der Gründung sowie Gründungsmethoden und Innovationsfähigkeit älterer Gründer behandelt. Die Untersuchung zeigt die Vielfalt älterer Gründertypen und gibt Hinweise darauf, wie ältere Gründer unterstützt werden können.
description: We have conducted a series of interviews in three German regions. The data from these regions provided an overview of typical economic structures in Germany (industrial, service, and agriculture regions). The bank perspective, the consultant perspective, and the founder perspective have been evaluated. The interviews concerned risk and insurance, financing, motivation and self-realization, satisfaction, time management, chances and obstacles, products, ideas, and sectors, red and blue ocean strategies, and founding methods. The investigation reveals a very large range of founder types and their special opportunities and problems and may indicate ways to promote the founding activities of the elderly.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Analysis of the Relation between Quadratic Unconstrained Binary Optimization (QUBO) and the Spin Glass Ground-State Problem

description: We analyze the transformation of QUBO from its conventional Boolean presentation into an equivalent spin glass problem with coupled $\pm1$ spin variables exposed to a site-dependent external field. We find that in a widely used testbed for QUBO these fields tend to be rather large compared to the typical coupling and many spins in each optimal configurations simply align with the fields irrespective of their constraints. Thereby, the testbed instances tend to exhibit large redundancies - seemingly independent variables which contribute little to the hardness of the problem, however. We demonstrate various consequences of this insight, for QUBO solvers as well as for heuristics developed for finding spin glass ground states. To this end, we implement the Extremal Optimization (EO) heuristic, in a new adaptation for the QUBO problem. We also propose a novel way to assess the quality of heuristics for increasing problem sizes based on asymptotic scaling.

description: The current distribution of language size in terms of speaker population is generally described using a lognormal distribution. Analyzing the original real data we show how the double-Pareto lognormal distribution can give an alternative fit that indicates the existence of a power law tail. A simple Monte Carlo model is constructed based on the processes of competition and fragmentation. The results reproduce the power law tails of the real distribution well and give better results for a poorly connected topology of interactions.
Thermodynamics and phase transition of rotating regular-de Sitter black holes
Creators: name: Ali, Md Sabir

Publisher: name: arXiv
Year: 2019
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We analyze thermodynamic properties of the rotating regular black holes having mass ($M$), angular momentum ($a$), and a magnetic charge $(g)$, and encompass Kerr black hole ($g=0$). The mass $M$ has a minimum at the radius $r_+=r_+^{\star}$, where both the heat capacity and temperature vanish. The thermal phase transition is because of the divergence of heat capacity at a critical radius $r_{+}^C$ with stable (unstable) branches for $r_+r_+^C$). We also generalize the rotating regular black holes in de Sitter (dS) background and analyzed its horizon structure to show that for each $g$, there are two critical values of the mass parameter $M_{\text{cr1}}$ and $M_{\text{cr2}}$ which correspond to the degenerate horizons. Thus, we have rotating regular-dS black holes with an additional cosmological horizon apart from the inner (Cauchy) and the outer (event) horizons. Next, we discuss the effective thermodynamic quantities of the rotating regular-dS black holes in the extended phase space where the cosmological constant ($Λ$) is considered as thermodynamic pressure. Combining the first laws at the two horizons, we calculate the heat capacity at constant pressure $C_P$, the volume expansion coefficient $α$, and the isothermal compressibility $κ_T$. At a critical point, the specific heat at constant pressure, the volume expansion coefficient, and the isothermal compressibility of the regular-dS black holes exhibit an infinite peak suggesting a second-order phase transition.

Tropical geometry over the tropical hyperfield

Publisher: name: arXiv
Year: 2019
Subjects: subject: Algebraic Geometry (math.AG)
subject: FOS: Mathematics

description: In this text, we merge ideas around the tropical hyperfield with the theory of ordered blueprints to give a new formulation of tropical scheme theory. The key insight is that a nonarchimedean absolute value can be considered as a morphism into the tropical hyperfield. In turn, ordered blueprints make it possible to consider the base change of a classical variety to the tropical hyperfield. We call this base change the scheme theoretic tropicalization of the classical variety. Our first main result describes the Berkovich analytification and the tropicalization of a classical variety as sets of rational points of scheme theoretic tropicalizations, including a characterization of the respective topologies. Our second main result shows that the Giansiracusa bend relations can be derived by a natural construction from the scheme theoretic tropicalization.

Artificial Intelligence Enhances the Performance of Chaos-based Wireless Communication

description: Some new findings for chaos-based wireless communication systems have been identified recently. First, chaos has proven to be the optimal communication waveform because chaotic signals can achieve the maximum signal to noise ratio at receiver with the simplest matched filter. Second, the information transmitted in chaotic signals is not modified by the multipath wireless channel. Third, chaos properties can be used to relief inter-symbol interference (ISI) caused by multipath propagation. Although recent work has reported the method of obtaining the optimal threshold to eliminate the ISI in chaos-based wireless communication, its practical implementation is still a challenge. By knowing the channel parameters and all symbols, especially the future symbol to be transmitted in advance, it is almost an impossible task in the practical communication systems. Owning to Artificial intelligence (AI) recent developments, Convolutional Neural Network (CNN) with deep learning structure is being proposed to predict future symbols based on the received signal, so as to further reduce ISI and obtain better bit error rate (BER) performance as compared to that used the existing sub-optimal threshold. The feature of the method involves predicting the future symbol and obtaining a better threshold suitable for time variant channel. Numerical simulation and experimental results validate our theory and the superiority of the proposed method.

description: We consider the group structure of quantum cellular automata (QCA) modulo circuits and show that it is abelian even without assuming the presence of ancillas, at least for most reasonable choices of control space; this is a corollary of a general method of ancilla removal. Further, we show how to define a group of QCA that is well-defined without needing to use families, by showing how to construct a coherent family containing an arbitrary finite QCA; the coherent family consists of QCA on progressively finer systems of qudits where any two members are related by a shallow quantum circuit. This construction applied to translation invariant QCA shows that all translation invariant QCA in three dimensions and all translation invariant Clifford QCA in any dimension are coherent.

description: A conjecture of Morel asserts that the sheaf of $\mathbb A^1$-connected components of a space is $\mathbb A^1$-invariant. Using purely algebro-geometric methods, we determine the sheaf of $\mathbb A^1$-connected components of a smooth projective surface, which is birationally ruled over a curve of genus $>0$. As a consequence, we show that Morel's conjecture holds for all smooth projective surfaces over an algebraically closed field of characteristic $0$.

description: The goal of this project is to present an idea to mimic the human vision i.e. the development of electronic eyes or Bionic Eyes with the aid of a nanosensor. In this project the progress made in the field of visual prosthesis, particularly in the photo-stimulation of a blind retina with the help of nanotechnology is discussed. A wire-free photo-reception approach has been adopted. A novel structure for the retinal photo-stimulation, based on a combination of two nanomaterial systems ideally suited for neurostimulation: semiconductor nanorods (NRs) and carbon nanotubes (CNTs) has been presented. The complete design paradigm along with the fabrication techniques adopted and the complete characterization of such complex optoelectronic systems has been given. It is our belief that successful stimulation of such a light-sensitive system suggests the potential use of these novel platform in future artificial retina applications.

description: We present a numerical study of ground states of the dilute versions of the Sherrington-Kirkpatrick (SK) mean-field spin glass. In contrast to so-called "sparse" mean-field spin glasses that have been studied widely on random networks of finite (average or regular) degree, the networks studied here are randomly bond-diluted to an overall density $p$, such that the average degree diverges as $\sim pN$ with the system size $N$. Ground-state energies are obtained with high accuracy for random instances over a wide range of fixed $p$. Since this is a NP-hard combinatorial problem, we employ the Extremal Optimization heuristic to that end. We find that the exponent describing the finite-size corrections, $ω$, varies continuously with $p$, a somewhat surprising result, as one would not expect that gradual bond-dilution would change the $T=0$ universality class of a statistical model. For $p\to1$, the familiar result of $ω(p=1)\approx\frac{2}{3}$ for SK is obtained.

description: Introduction: Human activities have resulted in global warming by high CO2 emissions. Poor dietary choices are linked to health diseases and high CO2 emissions. Most studies focus on the changes the average population diet, often suggesting radical changes to our diets. Methodology: An optimisation algorithm will be created to minimise CO2 emissions without changing greatly the current food intake of each individual. Diets of 212 individuals will be used, along with CO2 emissions for each food item in the sample. Results: Current diets contribute 6.94kg of CO2 emissions per person per day, which was reduced by 30% after the optimisation. 100 out of 212 individuals had an optimised diet as the result (47%). Meat and dairy contribute significantly more in CO2 emissions from diets compared to fruits and vegetables. Meat, dairy products, fruits and vegetables are 12% of our food intake each, however after the optimisation, meat and dairy were decreased by 23% whereas fruits and vegetables were increased by 30% and 4% respectively. Conclusions: Optimising food intake led to a healthy diet low in CO2 emissions by combining foods in current diets. It is possible to achieve this by making small changes to the food intake consumed.

description: We implement a three-body potential to model associative bond swaps, and release it as part of the HOOMD-blue software. The use of a three-body potential to model swaps has been proven to be effective and has recently provided useful insights into the mechanics and dynamics of adaptive network materials such as vitrimers. It is elegant because it can be used in plain molecular dynamics simulations without the need for topology-altering Monte Carlo steps, and naturally represents typical physical features such as slip-bond behavior. It is easily tunable with a single parameter to control the average swap rate. Here, we show how associative bond swaps can be used to speed up the equilibration of systems that self-assemble by avoiding traps and pitfalls, corresponding to long-lived metastable configurations. Our results demonstrate the possibilities of these swaps not only for modeling systems that are associative by nature, but also for increasing simulation efficiency in other systems that are modellable in HOOMD-blue.

description: Di era modern ini, berbagai masalah sosial muncul di wilayah perkotaan dan pedesaan, termasuk di kalangan remaja yang sering terlibat dalam tindakan pidana. Remaja dalam fase transisi dari anak-anak menuju dewasa sangat dipengaruhi oleh lingkungan, sehingga rentan melakukan perilaku menyimpang seperti penyalahgunaan narkoba. WHO menyatakan bahwa remaja adalah fase adaptasi dari anak menuju dewasa, dengan rentang usia 12 hingga 24 tahun. Kenakalan remaja yang tidak ditangani dengan baik dapat berkembang menjadi pelanggaran hukum serius, terutama bagi mereka dari keluarga tidak stabil. Dukungan sosial yang memadai dari keluarga, teman, dan lingkungan sangat penting untuk membantu remaja mengatasi dampak negatif dari konflik hukum dan meningkatkan kesejahteraan psikologis mereka. Penelitian ini mengkaji pengaruh dukungan sosial terhadap kesejahteraan psikologis remaja berkonflik hukum di Lapas X, menggunakan pendekatan kuantitatif dengan regresi linear dan melibatkan 150 remaja laki-laki berusia 18-22 tahun sebagai sampel. Instrumen penelitian menggunakan skala Guttman dengan uji validitas dan reliabilitas yang memadai. Hasil penelitian menunjukkan hubungan positif signifikan antara dukungan sosial dan kesejahteraan psikologis, dengan koefisien korelasi 0,851 dan kontribusi sebesar 72,4%. Kesimpulan menegaskan pentingnya meningkatkan dukungan sosial untuk kesejahteraan psikologis remaja berkonflik hukum, serta menyarankan penelitian lebih lanjut dengan jumlah responden lebih besar. Penelitian ini memberikan wawasan penting bagi lembaga pemasyarakatan dalam upaya rehabilitasi remaja serta pengembangan program intervensi yang efektif.

description: We construct a series of homomorphisms from the $Y$-filtration on the monoid of homology cylinders to torsion modules via the mod $\mathbb{Z}$ reduction of the LMO functor. The restriction of our homomorphism to the lower central series of the Torelli group does not factor through Morita's refinement of the Johnson homomorphism. We use it to show that the abelianization of the Johnson kernel of a closed surface has torsion elements. We also determine the third graded quotient $Y_3\mathcal{IC}_{g,1}/Y_4$ of the $Y$-filtration.

description: This article explores the metaphor of Science as provider of sharp images of our environment, using the epistemological framework of Objective Cognitive Constructivism. These sharp images are conveyed by precise scientific hypotheses that, in turn, are encoded by mathematical equations. Furthermore, this article describes how such knowledge is produced by a cyclic and recursive develop, perfection and reinforcement process, leading to the emergence of eigen-solutions characterized by the four essential properties of precision, stability, separability and composability. Finally, this article discusses the role played by ontology and metaphysics in the scientific production process, and in which sense the resulting knowledge can be considered objective.
A Bounded Measure for Estimating the Benefit of Visualization

description: Information theory can be used to analyze the cost-benefit of visualization processes. However, the current measure of benefit contains an unbounded term that is neither easy to estimate nor intuitive to interpret. In this work, we propose to revise the existing cost-benefit measure by replacing the unbounded term with a bounded one. We examine a number of bounded measures that include the Jenson-Shannon divergence and a new divergence measure formulated as part of this work. We use visual analysis to support the multi-criteria comparison, narrowing the search down to those options with better mathematical properties. We apply those remaining options to two visualization case studies to instantiate their uses in practical scenarios, while the collected real world data further informs the selection of a bounded measure, which can be used to estimate the benefit of visualization.

description: Shear-wave elastography (SWE) measures shear-wave speed (SWS), which is related to the underlying shear modulus of soft tissue. SWE methods generally assume that soft tissue viscoelasticity is independent of mechanical loading, however, soft tissues are known to have viscoelasticity changing nonlinearly with pre-compression. Hence, characterization by SWS alone is insufficient, where nonlinear properties can be seen as confounders but may also be utilized as additional bio-markers. The viscoelastic nature of a medium is fully characterized by its storage and loss moduli, which are related to SWS and shear-wave attenuation (SWA). In this work, we study SWA characteristics as a function of applied strain to measure nonlinear viscoelastic parameters in soft tissues. For this purpose, we apply incremental quasi-static compression on the samples while measuring SWS and SWA, from which we derive storage and loss moduli to estimate nonlinear viscoelastic parameters as a function of applied strain using acoustoelasticity (AE) theory. Results from tissue-mimicking phantoms with varying oil percentages and ex-vivo porcine liver experiments demonstrate the feasibility of the proposed approach. In both these experiments, SWA was observed to decrease with applied strain. For 10 % compression in ex-vivo livers, shear-wave attenuation decreased on average by 28 % (93 Np/m), while SWS increased on average by 20 % (0.26 m/s).

description: The Hessian matrix plays an important role in correct interpretation of the multiple scattered wave fields inside the FWI frame work. Due to the high computational costs, the computation of the Hessian matrix is not feasible. Consequently, FWI produces overburden related artifacts inside the target zone model, due to the lack of the exact Hessian matrix. We have shown here that Marchenko-based target-oriented Full Waveform Inversion can compensate the need of Hessian matrix inversion by reducing the non-linearity due to overburden effects. This is achieved by exploiting Marchenko-based target replacement to remove the overburden response and its interactions with the target zone from residuals and inserting the response of the updated target zone into the response of the entire medium. We have also shown that this method is more robust with respect to prior information than the standard gradient FWI. Similarly to standard Marchenko imaging, the proposed method only requires knowledge of the direct arrival time from a focusing point to the surface and the reflection response of the medium.
