description: We put together the experimental results on muon component of extensive air showers (EAS) which were gained with various techniques at the detector complex of the Tien Shan mountain station. According to this comparison, the problem of the EAS muon content in the range of primary cosmic ray energies (1-100)PeV seems to be more complicated than it was usually supposed. Generally, from the models of nuclear interaction it follows that the EAS which have produced gamma-hadron families in the Tien Shan X-ray emulsion chamber did preferably originate from interaction of the light cosmic ray nuclei, such that their muon abundance must be ~1.5 times below an average calculated over all showers. In contrary, the experimental muon counts in the EAS with families demonstrate a (1.5-2)-fold excess above the average, and this difference starts to be observable in the showers with the energy above the 3PeV knee of the primary cosmic ray spectrum. Later on, the rise of muon production in EAS after the knee was confirmed at Tien Shan by another experiment on detection of the neutrons stemmed from interaction of cosmic ray muons. Thus, the results obtained by the two completely different methods do mutually agree with each other but contradict to the common models of hadron interaction.

description: Immer wieder kann eine synonyme Verwendung der Begriffe 'Islamfeindlichkeit' und 'Muslim*innenfeindlichkeit' beobachtet werden, was den Eindruck erwecken kann, es handele sich hierbei um dasselbe Phänomen. Mittlerweile gibt es jedoch sowohl theoretische Überlegungen zu einer potentiellen Differenzierung von feindlichen Einstellungen gegenüber der Religion des Islams und feindlichen Einstellungen gegenüber Menschen muslimischen Glaubens als auch empirische Evidenz für zwei statistisch unterscheidbare Dimensionen. Dieser Beitrag überträgt die theoretischen Überlegungen und die empirischen Befunde aus der Wissenschaft auf die Praxis und lotet Implikationen und Potentiale einer differenzierten Betrachtung von Islam- und Muslim*innenfeindlichkeit für die Soziale Arbeit aus.

description: We report a study of the low-lying states of deformed $^{21}$Ne within the framework of quantum-number projected generator coordinate method (PGCM), starting from a chiral two-nucleon-plus-three-nucleon (NN+3N) interaction. The wave functions of states are constructed as a linear combination of a set of axially-deformed Hartree-Fock-Bogliubov (HFB) wave functions with different quadrupole deformations. These HFB wave functions are projected onto different angular momenta and the correct neutron and proton numbers for $^{21}$Ne. The results of calculations based on the effective Hamiltonians derived by normal-ordering the 3N interaction with respect to three different reference states, including the quantum-number projected HFB wave functions for $^{20}$Ne, $^{22}$Ne, and an ensemble of them with equal weights, are compared. This study serves as a key step towards ab initio calculations of odd-mass deformed nuclei with the in-medium GCM.

description: We study singular real-analytic Levi-flat hypersurfaces in complex projective space. We define the rank of an algebraic Levi-flat hypersurface and study the connections between rank, degree, and the type and size of the singularity. In particular, we study degenerate singularities of algebraic Levi-flat hypersurfaces. We then give necessary and sufficient conditions for a Levi-flat hypersurface to be a pullback of a real-analytic curve in $\mathbb{C}$ via a meromorphic function. Among other examples, we construct a nonalgebraic semianalytic Levi-flat hypersurface with compact leaves that is a perturbation of an algebraic Levi-flat variety.

description: Many data analysis methods cannot be applied to data that are not represented by a fixed number of real values, whereas most of real world observations are not readily available in such a format. Vector based data analysis methods have therefore to be adapted in order to be used with non standard complex data. A flexible and general solution for this adaptation is to use a (dis)similarity measure. Indeed, thanks to expert knowledge on the studied data, it is generally possible to define a measure that can be used to make pairwise comparison between observations. General data analysis methods are then obtained by adapting existing methods to (dis)similarity matrices. In this article, we propose an adaptation of Kohonen's Self Organizing Map (SOM) to (dis)similarity data. The proposed algorithm is an adapted version of the vector based batch SOM. The method is validated on real world data: we provide an analysis of the usage patterns of the web site of the Institut National de Recherche en Informatique et Automatique, constructed thanks to web log mining method.
Sexuelle Bildung und ihre Ungleichwertigkeiten

description: Auch die Sexualpädagogik hat in den letzten Jahren ihren Schwerpunkt zunehmend auf die Normalisierung von Vielfalt gelegt. Dabei geht es nicht nur um die sexuelle Vielfalt und die Anerkennung vielfältiger Lebensformen, sondern auch um den Umgang mit Differenzen jenseits der Sexualität und ihren Verknüpfungen mit dieser. Ziel ist es einen möglichst diskriminierungsfreien Raum zu schaffen, um Sexualität als eine biographisch relevante Größe aller Menschen zu behandeln und gleichzeitig dadurch deutlich zu machen, dass Sexualität immer auch ein gesellschaftlicher Faktor ist. In diesem Beitrag wird diese gesellschaftliche Relevanz von Sexualität mithilfe des Intersektionalitätskonzept deutlich gemacht, um aufzuzeigen, dass eine sexuelle Bildung, die sich mit Vielfalt auseinander setzt, immer auch Ungleichheitsstrukturen im Blick haben muss. Denn Sexualität ist, wie andere Ungleichheitskategorien auch, immer gekoppelt und verwoben mit verschiedenen Diskriminierungsdimensionen und muss daher intersektional verstanden werden.

THE CONTRIBUTION OF HERBERT SIMON'S THEORY  READAPTATION OF THE CUSTOMS DECLARATION MODEL : case of Morocco

Subjects: Bounded rationality ; customs declaration ; decision process ; adaptation ; risk analysis.

description: In the context of international trade, and whatever the means of transport used, all customs operations must be carried out under cover of a single customs declaration model. This article attempts to analyze this model which constitutes the informational basis of the customs risk analysis approach by mobilizing the theory of limited rationality of Herbert Simon as well as its derived model. This approach through the paradigm of limited rationality teaches us that customs has created its own limited rationality and continues on this path by limiting itself to a model which has not undergone any development or innovation which allows its enrichment with strategic information.This model remains limited in information and is no longer representative of the layout of the current customs environment. The absence of representative information from several stakeholders and interventions in the customs operations flow circuit constitutes the manifestation of this reality. Consequently, this declaration model is becoming obsolete and requires its adaptation to the profile of international trade and the international value chain in order to improve rationality in the decision-making process.

Für die empirische Betrachtung und Reflexion wird ethnografisches Material, aus einem situationsanalytischen Forschungsprojekt (Dissertationsprojekt) herangezogen. Anhand der analytischen Erkenntnisse kann gezeigt werden, wie Differenzen im schulischen Handlungsfeld und damit im Kontext (sozial-)pädagogischer Praxis in Bezug auf neuzugewanderte Kinder und Jugendliche nicht nur produziert werden. Vielmehr verdeutlichen sich dabei Differenzmarkierungen in denen kulturalisierende und ethnisierende Adressierungspraxen enthalten sind, die letztendlich auf eine diskursive Zugehörigkeitsordnung in der Migrationsgesellschaft verweisen.

description: Super-puffs -- low-mass exoplanets with extremely low bulk density -- are attractive targets for exploring their atmospheres and formation processes. Recent studies suggested that the large radii of super-puffs may be caused by atmospheric dust entrained in the escaping atmospheres. In this study, we investigate how the dust grows in escaping atmospheres and influence the transit radii using a microphysical model of grain growth. Collision growth is efficient in many cases, leading to hinder the upward transport of dust via enhanced gravitational settling. We find that dust abundance in the outflow hardly exceeds the Mach number at the dust production region. Thus, dust formed at upper atmospheres, say $P\lesssim{10}^{-5}$ bar, are needed to launch a dusty outflow with high dust abundance. With sufficiently high dust production altitudes and rates, the dusty outflow can enhance the observable radius by a factor of $\sim$2 or even more. We suggest that photochemical haze is a promising candidate of high-altitude dust that can be entrained in the outflow. We also compute the synthetic transmission spectra of super-puff atmospheres and demonstrate that the dusty outflow produces a broad spectral slope and obscures molecular features, in agreement with recently reported featureless spectra. Lastly, using an interior structure model, we suggest that the atmospheric dust could drastically enhance the observable radius only for planets in a narrow mass range of $\sim2$--$5M_{\rm \oplus}$, in which the boil-off tends to cause total atmospheric loss. This may explain why super-puffs are uncommon despite the suggested universality of photochemical hazes.

Auch die Fachkräfte der Sozialen Arbeit haben es sich zu Aufgabe gemacht, Unrechtserfahrung zu bekämpfen, wozu auch Rassismuserfahrungen zählen. Um jedoch dem sozialarbeiterischen Auftrag gerecht zu werden, sind Sozialarbeitende dazu angehalten, ihre Eigenbeteiligung an (re-)produzierenden Prozessen rassismuskritisch zu hinterfragen. Dieser Beitrag erläutert zunächst, was unter soziale Bewegung zu verstehen ist. Anschließend daran wird der Entstehungskontext der BLM wiedergegeben, um dann schlussendlich der Frage nachzugehen, wie Fachkräfte der Sozialen Arbeit auf soziale Bewegungen reagieren sollten. Hierzu werden zum Schluss zwei Handlungsperspektiven für Sozialarbeitende formuliert.

description: We develop an experimental algorithm for the exact solving of the maximum independent set problem. The algorithm consecutively finds the maximal independent sets of vertices in an arbitrary undirected graph such that the next such set contains more elements than the preceding one. For this purpose, we use a technique, developed by Ford and Fulkerson for the finite partially ordered sets, in particular, their method for partition of a poset into the minimum number of chains with finding the maximum antichain. In the process of solving, a special digraph is constructed, and a conjecture is formulated concerning properties of such digraph. This allows to offer of the solution algorithm. Its theoretical estimation of running time equals to is $O(n^{8})$, where $n$ is the number of graph vertices. The offered algorithm was tested by a program on random graphs. The testing the confirms correctness of the algorithm.

description: We investigate Einstein-Gauss-Bonnet (EGB) 4D massive gravity coupled to nonlinear electrodynamics (NED) in an Anti-de-Sitter (AdS) background and find an exact magnetically charged black hole solution. The metric function was analyzed for different values of massive gravity parameters. We verified the first law of black hole thermodynamics and the generalized Smarr formula, treating the cosmological constant as thermodynamic pressure. Vacuum polarization is defined as the conjugate to the NED parameter. To analyze the local stability of the black hole, we compute specific heat. We investigated the Van der Waals-like/reentrant phase transition of the black holes and estimated the critical points. We observed small/large black hole (SBH/LBH) and small/intermediate/large black hole (SBH/IBH/LBH) phase transitions. The Joule-Thomson coefficient, inversion, and isenthalpic curves are discussed. Finally, the minimum inversion temperature and the corresponding event horizon radius are obtained using numerical techniques.

description: In data analysis new forms of complex data have to be considered like for example (symbolic data, functional data, web data, trees, SQL query and multimedia data, ...). In this context classical data analysis for knowledge discovery based on calculating the center of gravity can not be used because input are not $\mathbb{R}^p$ vectors. In this paper, we present an application on real world symbolic data using the self-organizing map. To this end, we propose an extension of the self-organizing map that can handle symbolic data.

The molecular specimen will be held on a free-standing sheet of graphene. Due to the high conductivity of graphene, electrons lost by ionization would be rapidly replaced, enabling repeated nondestructive interrogation. Limits of resolution, maximum particle size and required electron flux are assessed.

description: Let $G$ be a group acting continuously on a space $X$ and let $X/G$ be its orbit space. Determining the topological or cohomological type of the orbit space $X/G$ is a classical problem in the theory of transformation groups. In this paper, we consider this problem for cohomology lens spaces. Let $X$ be a finitistic space having the mod 2 cohomology algebra of the lens space $L_p^{2m-1}(q_1,...,q_m)$. Then we classify completely the possible mod 2 cohomology algebra of orbit spaces of arbitrary free involutions on $X$. We also give examples of spaces realizing the possible cohomology algebras. In the end, we give an application of our results to non-existence of $\mathbb{Z}_2$-equivariant map $\mathbb{S}^n \to X$.

description: Recent work has demonstrated the viability of using crowdsourcing as a tool for evaluating the truthfulness of public statements. Under certain conditions such as: (1) having a balanced set of workers with different backgrounds and cognitive abilities; (2) using an adequate set of mechanisms to control the quality of the collected data; and (3) using a coarse grained assessment scale, the crowd can provide reliable identification of fake news. However, fake news are a subtle matter: statements can be just biased ("cherrypicked"), imprecise, wrong, etc. and the unidimensional truth scale used in existing work cannot account for such differences. In this paper we propose a multidimensional notion of truthfulness and we ask the crowd workers to assess seven different dimensions of truthfulness selected based on existing literature: Correctness, Neutrality, Comprehensibility, Precision, Completeness, Speaker's Trustworthiness, and Informativeness. We deploy a set of quality control mechanisms to ensure that the thousands of assessments collected on 180 publicly available fact-checked statements distributed over two datasets are of adequate quality, including a custom search engine used by the crowd workers to find web pages supporting their truthfulness assessments. A comprehensive analysis of crowdsourced judgments shows that: (1) the crowdsourced assessments are reliable when compared to an expert-provided gold standard; (2) the proposed dimensions of truthfulness capture independent pieces of information; (3) the crowdsourcing task can be easily learned by the workers; and (4) the resulting assessments provide a useful basis for a more complete estimation of statement truthfulness.

Subjects: subject: Logic in Computer Science (cs.LO)

description: In the logic programming paradigm, a program is defined by a set of methods, each of which can be executed when specific conditions are met during the current state of an execution. The semantics of these programs can be elegantly represented using sequent calculi, in which each method is linked to an inference rule. In this context, proof search mirrors the program's execution. Previous works introduced a framework in which the process of constructing proof nets is employed to model executions, as opposed to the traditional approach of proof search in sequent calculus.
 This paper further extends this investigation by focussing on the pure multiplicative fragment of this framework. We demonstrate, providing practical examples, the capability to define logic programming methods with context-sensitive behaviors solely through specific resource-preserving and context-free operations, corresponding to certain generalized multiplicative connectives explored in existing literature. We show how some of these methods, although still multiplicative, escape the purely multiplicative fragment of Linear Logic (MLL).

description: We employ the phenomenological Lawrence-Doniach model to compute the contributions of the superconducting fluctuations to the third-harmonic magnetic response, denoted here by $\overline{M_{3}}$, which can be measured in a precise way using ac magnetic fields and lock-in techniques. We show that, in an intermediate temperature regime, this quantity behaves as the third-order nonlinear susceptibility, which shows a power-law dependence with the reduced temperature $ε=\frac{T-T_{c}}{T_{c}}$ as $ε^{-5/2}$. Very close to $T_{c}$, however, $\overline{M_{3}}$ saturates due to the nonzero amplitude of the ac field. We compare our theoretical results with experimental data for three conventional superconductors -- lead, niobium, and vanadium -- and for the unconventional superconductor Sr$_{2}$RuO$_{4}$ (SRO). We find good agreement between theory and experiment for the elemental superconductors, although the theoretical values for the critical field systematically deviate from the experimental ones. In the case of SRO, however, the phenomenological model completely fails to describe the data, as the third-harmonic response remains sizable over a much wider reduced temperature range compared to Pb, Nb, and V. We show that an inhomogeneous distribution of $T_{c}$ can partially account for this discrepancy, since regions with a locally higher $T_{c}$ contribute to the fluctuation $\overline{M_{3}}$ significantly more than regions with the "nominal" $T_{c}$ of the clean system. However, the exponential temperature dependence of $\overline{M_{3}}$ first reported in Ref. [3] is not captured by the model with inhomogeneity. We conclude that, while inhomogeneity is an important ingredient to understand the superconducting fluctuations of SRO and other perovskite superconductors, additional effects may be at play, such as non-Gaussian fluctuations or rare-region effects.

description: We study theoretically the length dependence of both conductance and thermopower in metal-molecule-metal junctions made up of dithiolated oligophenylenes contacted to gold electrodes. We find that while the conductance decays exponentially with increasing molecular length, the thermopower increases linearly as suggested by recent experiments. We also analyze how these transport properties can be tuned with methyl side groups. Our results can be explained by considering the level shifts due to their electron-donating character as well as the tilt-angle dependence of conductance and thermopower. Qualitative features of the substituent effects in our density-functional calculations are explained using a tight-binding model. In addition, we observe symmetry-related even-odd transmission channel degeneracies as a function of molecular length.

description: Accurate brain tumor segmentation in the early stages of the disease is crucial for the treatment's effectiveness, avoiding exhaustive visual inspection of a qualified specialist on 3D MR brain images of multiple protocols (e.g., T1, T2, T2-FLAIR, T1-Gd). Several networks exist for Glioma segmentation, being nnU-Net one of the best. In this work, we evaluate self-calibrated convolutions in different parts of the nnU-Net network to demonstrate that self-calibrated modules in skip connections can significantly improve the enhanced-tumor and tumor-core segmentation accuracy while preserving the wholetumor segmentation accuracy.

Okanagana occidentalis

description: Okanagana occidentalis (Walker in Lord, 1866)
Cicada occidentalis — Walker in Lord, 1866: 339.
Tibicen occidentalis — Woodworth, 1888: 68 (Incorrect synonymy).
Okanagana occidentalis — Van Duzee, 1915: 44 (Revised status).
Okanagana lurida — Davis, 1919: 192. New junior subjective synonym
Type locality: Canada, British Columbia, Chilliwack (Sanborn & Webb 2001). Lectotype deposited in the British Museum of Natural History (Sanborn & Heath 2017).
Rationale for synonymy: O. lurida from British Columbia, Canada, resolved at the crown of a paraphyletic grade of multiple samples of O. occidentalis (Figs. 4–7) separated by negligible genetic distance (COI uncorrected distance 0.00–1.45%; Supp. Table 2). We conclude that O. lurida is an uncommon color pattern variant of O. occidentalis (Fig. 12). Davis (1926, 1939) remarked upon the similarity between the two species in appearance and on the geographic distribution shared with O. occidentalis (Sanborn & Phillips 2013). Examination of numerous specimens of O. lurida in SEMK and CAS confirm that this color pattern variant occurs among specimens of O. occidentalis from throughout the distribution. Field observations have found O. lurida among large numbers of O. occidentalis (JAC, pers. obs.). O. lurida is therefore made a junior subjective synonym of O. occidentalis.

Local assessment of transient stability for generator tripping
Creators: name: Mihirig, Ali Mohamed
Publisher: name: University of British Columbia
Year: 2010

description: The local variables of a synchronous generator are investigated as possible indicators of the transient stability of the generator. A number of case studies are carried out on three test systems to find out which generator variable or variables can be used. By comparing the conventional swing curve of each generator with its local acceleration curve during the same transient period, a new criterion for transient stability assessment is developed to replace existing generator tripping schemes that rely upon pre-determined contingency studies. The new criterion is based upon the behavior of the acceleration of the generator following a disturbance to the system. No measurements from any other machine in the system are required to assess the stability of the generator.

description: Charged particle therapy (CPT) is an advanced modality of radiation therapy which has grown rapidly worldwide, driven by recent developments in technology and methods of delivery. To ensure safe and high quality treatments, various instruments are used for a range of different measurements such as for quality assurance, monitoring and dosimetry purposes. With the emergence of new and enhanced delivery techniques, systems with improved capabilities are needed to exceed existing performance limitations of conventional tools. The Medipix3 is a hybrid pixel detector able to count individual protons with millisecond time resolution at clinical flux with near instant readout and count rate linearity. The system has previously demonstrated use in medical and other applications, showing wide versatility and potential for particle therapy. In this work we present measurements of the Medipix3 detector in the 60 MeV ocular proton therapy beamline at the Clatterbridge Cancer Centre, UK. The beam current and lateral beam profiles were evaluated at multiple positions in the treatment line and compared with EBT3 Gafchromic film. The recorded count rate linearity and temporal analysis of the beam structure was measured with Medipix3 across the full range of available beam intensities, up to $3.12 \times 10^{10}$ protons/s. We explore the capacity of Medipix3 to provide non-reference measurements and its applicability as a tool for dosimetry and beam monitoring for CPT. This is the first known time the performance of the Medipix3 detector technology has been tested within a clinical, high proton flux environment.

description: Dr. Jens Bakker, Islamwissenschaftler mit Schwerpunkt auf Geistes- und Wissenschaftsgeschichte der islamischen Welt und Mitglied der Forschungsgruppe „Soziale Arbeit in der Migrationsgesellschaft“ am Institut für Islamische Theologie der Universität Osnabrück, zeigt in diesem als Einführung konzipierten Artikel, dass Wohlfahrtspflege zur Lebensmitte der islamischen Religion gehört, also eines ihrer zentralen Anliegen bildet. Dazu werden Offenbarungstexte und Quellen für die klassische Theologie des sunnitischen Islam betrachtet, die Arten und Normativität der Wohlfahrtspflege behandeln: Es wird deutlich, dass die Forderung, in der Gesellschaft Bedarfsausgleich zu schaffen, zu den ältesten Elementen der islamischen Offenbarung gehört und in der historisch wirkmächtigsten Ausprägung sunnitischer Theologie verschiedene Handlungsformen hinsichtlich ihrer Verbindlichkeit und konkreten Gestalt differenziert diskutiert werden. Außerdem wird einschlägige Sekundärliteratur herangezogen, die einen Blick in die Umsetzung der Forderung der Religion nach Wohlfahrtspflege in der Geschichte erlaubt.

description: For dark matter (DM) direct detections, the kinematic effects such as those of the inelastic scattering can play important role in light DM searches. The light DM detection is generally difficult because of its small recoil energy. But the recoil energy of the exothermic inelastic DM scattering could exceed the detection threshold due to the contribution from the DM mass-splitting, making the direct detection of sub-GeV DM feasible. In this work, we systematically study signatures of the light exothermic inelastic DM from the recoil spectra including both the DM-electron scattering and Migdal effect. Such inelastic DM has mass around (sub-)GeV scale with DM mass-splitting of $O(1-10^2)$keV. We analyze the direct detection sensitivities to such light inelastic DM. For different inelastic DM masses and mass-splittings, we find that the DM-electron recoil and Migdal effect can contribute significantly and differently to the direct detection signatures. The DM-lepton and/or DM-quark interactions may vary for different DM models, and their interplay leads to a diversity in the recoil spectra. Hence, it is important to perform a combined analysis to include both the DM-electron recoil and Migdal effect. We further demonstrate that this analysis has strong impacts on the cosmological and laboratory bounds for the inelastic DM.
