description: We present the spectral energy distributions (SEDs) of a hard X-ray selected sample. The sample contains 136 sources with F(2-10 keV)>10^-14 erg/cm^2/s and 132 are AGNs. The sources are detected in a 1 square degree area of the XMM-Newton-Medium Deep Survey where optical data from the VVDS, CFHTLS surveys, and infrared data from the SWIRE survey are available. Based on a SED fitting technique we derive photometric redshifts with sigma(1+z)=0.11 and 6% of outliers and identify AGN signatures in 83% of the objects. This fraction is higher than derived when a spectroscopic classification is available. The remaining 17+9-6% of AGNs shows star-forming galaxy SEDs (SF class). The sources with AGN signatures are divided in two classes, AGN1 (33+6-1%) and AGN2 (50+6-11). The AGN1 and AGN2 classes include sources whose SEDs are fitted by type 1 and type 2 AGN templates, respectively. On average, AGN1s show soft X-ray spectra, consistent with being unabsorbed, while AGN2s and SFs show hard X-ray spectra, consistent with being absorbed. The analysis of the average SEDs as a function of X-ray luminosity shows a reddening of the IR SEDs, consistent with a decreasing contribution from the host galaxy at higher luminosities. The AGNs in the SF classes are likely obscured in the mid-infrared, as suggested by their low L(3-20micron)/Lcorr(0.5-10 keV) ratios. We confirm the previously found correlation for AGNs between the radio luminosity and the X-ray and the mid-infrared luminosities. The X-ray-radio correlation can be used to identify heavily absorbed AGNs. However, the estimated radio fluxes for the missing AGN population responsible for the bulk of the background at E>10 keV are too faint to be detected even in the deepest current radio surveys.

description: The random motion of a Brownian particle confined in some finite domain is considered. Quite generally, the relevant statistical properties involve infinite series, whose coefficients are related to the eigenvalues of the diffusion operator. Unfortunately, the latter depend on space dimensionality and on the particular shape of the domain, and an analytical expression is in most circumstances not available. In this article, it is shown that the series may in some circumstances sum up exactly. Explicit calculations are performed for 2D diffusion restricted to a circular domain and 3D diffusion inside a sphere. In both cases, the short-time behaviour of the mean square displacement is obtained.

description: The breakdown of finite element (FEM) computations for the flow of an Oldroyd-B fluid around a cylinder confined between parallel plates, at Weissenberg numbers Wi = O(1), is shown to arise due to a coil-stretch transition experienced by polymer molecules traveling along the centerline in the wake of the cylinder. With increasing Wi, the coil-stretch transition leads to an unbounded growth in the stress maximum in the cylinder wake. Finite element computations for a FENE-P fluid reveal that, although polymer molecules undergo a coil-stretch transition in the cylinder wake, the mean extension of the molecules saturates to a value close to the fully extended length, leading to bounded stresses with increasing Wi. The existence of a coil-stretch transition has been deduced by examining the behavior of ultra-dilute Oldroyd-B and FENE-P fluids. In this case, the solution along the centerline in the cylinder wake can be obtained exactly since the velocity field is uncoupled from the stress and conformation tensor fields. Estimation of the number of finite elements required to achieve convergence reveals the in-feasibility of obtaining solutions for the Oldroyd-B model for Wi > 1.

description: To understand large, connected systems, we cannot only zoom into the details. We also need to see the large-scale features from afar. One way to take a step back and get the whole picture is to model the systems as a network. However, many systems are not static, but consisting of contacts that are off and on as time progresses. This Chapter introduces the mathematical and computational modeling of such systems and thus an introduction to the rest of the book. We will cover some of the earlier developments that form the foundation for the more specialized topics of the other Chapters.

description: Based on a Glauber model, a statistical analysis of all mid-rapidity J/psi hadroproduction and leptoproduction data on nuclear targets is carried out. This allows us to determine the J/psi-nucleon inelastic cross section, whose knowledge is crucial to interpret the J/psi suppression observed in heavy-ion collisions, at SPS and at RHIC. The values of sigma are extracted from each experiment. A clear tension between the different data sets is reported. The global fit of all data gives sigma=3.4+/-0.2 mb, which is significantly smaller than previous estimates. A similar value, sigma=3.5+/-0.2 mb, is obtained when the nDS nuclear parton densities are included in the analysis, although we emphasize that the present uncertainties on gluon (anti)shadowing do not allow for a precise determination of sigma. Finally, no significant energy dependence of the J/psi-N interaction is observed, unless strong nuclear modifications of the parton densities are assumed.

description: Electron transmission through nanosystems is blocked if there are no states connecting the left and the right reservoir. Electron-electron scattering can lift this blockade and we show that this feature can be conveniently implemented by considering a transport model based on many-particle states. We discuss typical signatures of this phenomena, such as the presence of a current signal for a finite bias window.

description: We study the $D^+ \to π^+ ηη$ and $D^+ \to π^+ π^0 η$ reactions, which are single Cabibbo suppressed and can proceed both through internal and external emission. The primary mechanisms at quark level are considered, followed by hadronization to produce three mesons in the $D^+$ decay, and after that the final state interaction of these mesons leads to the production of the $a_0(980)$ resonance, seen in the $π^+ η$, $π^0 η$ mass distributions. The theory has three unknown parameters to determine the shape of the distributions and the ratio between the $D^+ \to π^+ ηη$ and $D^+ \to π^+ π^0 η$ rates. This ratio restricts much the sets of parameters but there is still much freedom leading to different shapes in the mass distributions. We call for a measurement of these mass distributions that will settle the reaction mechanism, while at the same time provide relevant information on the way that the $a_0(980)$ resonance is produced in the reactions.

description: We present novel data-processing inequalities relating the mutual information and the directed information in systems with feedback. The internal blocks within such systems are restricted only to be causal mappings, but are allowed to be non-linear, stochastic and time varying. These blocks can for example represent source encoders, decoders or even communication channels. Moreover, the involved signals can be arbitrarily distributed. Our first main result relates mutual and directed informations and can be interpreted as a law of conservation of information flow. Our second main result is a pair of data-processing inequalities (one the conditional version of the other) between nested pairs of random sequences entirely within the closed loop. Our third main result is introducing and characterizing the notion of in-the-loop (ITL) transmission rate for channel coding scenarios in which the messages are internal to the loop. Interestingly, in this case the conventional notions of transmission rate associated with the entropy of the messages and of channel capacity based on maximizing the mutual information between the messages and the output turn out to be inadequate. Instead, as we show, the ITL transmission rate is the unique notion of rate for which a channel code attains zero error probability if and only if such ITL rate does not exceed the corresponding directed information rate from messages to decoded messages. We apply our data-processing inequalities to show that the supremum of achievable (in the usual channel coding sense) ITL transmission rates is upper bounded by the supremum of the directed information rate across the communication channel. Moreover, we present an example in which this upper bound is attained. Finally, ...

In this note some basic elements of geometry of these domains are introduced and an analogue of the C-spectral sequence in this context is studied. This, in particular, allows cohomological interpretation and analysis of initial data, boundary conditions, etc, for general partial differential equations and of transversality conditions in calculus of variations. This kind applications and extensions to arbitrary diffieties will be considered in subsequent publications.

The Pastoral After Environmentalism: Nature and Culture in Stephen Albert’s Symphony: RiverRun
Creators: name: Watkins, Holly
Publisher: name: Current Musicology
Year: 2007

description: In the arts, a suspicion of progress narratives, which had been gathering steam in the 1960s, fueled the search for alternatives to modernism and its principals of artistic autonomy, abstraction and the evolution of technique. Just as the revival of tonality has inspired controversy among composers and music critics committed to modernist ideals, the reemergence of a relatively tradition form of the pastoral raises questions about the significance of this genre in the late twentieth and early twenty-first centuries. Viewed in tandem with official and grass roots efforts to stem the tide of environmental damage, the pastoral's traditional themes of innocence and retreat into nature might appear merely quaint, or even dangerously out of touch with a world in need of concrete solutions to problems of global proportions.

description: We report the magnetic susceptibility and NMR studies of a spin-gapped layered compound Na2Cu2TeO6 (the spin gap $Δ\sim$ 250 K), the hole doping effect on the Cu2TeO6 plane via a topochemical Na deficiency by soft chemical treatment, and the static spin vacancy effect by nonmagnetic impurity Zn substitution for Cu. A finite Knight shift at the $^{125}$Te site was observed for pure Na2Cu2TeO6. The negative hyperfine coupling constant $^{125}A_{tr}$ is an evidence for the existence of a superexchange pathway of the Cu-O-Te-O-Cu bond. It turned out that both the Na deficiency and Zn impurities induce a Curie-type magnetism in the uniform spin susceptibility in an external magnetic field of 1 T, but only the Zn impurities enhance the low-temperature $^{23}$Na nuclear spin-lattice relaxation rate whereas the Na deficiency suppresses it. A spin glass behavior was observed for the Na-deficient samples but not for the Zn-substituted samples. The dynamics of the unpaired moments of the doped holes are different from that of the spin vacancy in the spin-gapped Cu2TeO6 planes.

description: The last 15 years have witnessed important progresses in our understanding of the mechanism of superconductivity in the high-$T_{c}$ cuprates. There is now strong evidence that the strange metal behavior is induced by the quantum critical fluctuation at the pseudogap end point, where the Fermi surface changes its topology from hole-like to electron-like. However, experiments show that the quantum critical behavior in the high-$T_{c}$ cuprates is qualitatively different from that observed in the heavy Fermion systems and the iron-based superconductors, in both of which the quantum critical behavior can be attributed to the quantum phase transition toward a symmetry breaking phase. The fact that the pseudogap exists as a spectral gap without a corresponding symmetry breaking order, together with the fact that the strange metal behavior occurs as a quantum critical behavior without a corresponding symmetry breaking phase transition, exposes the central difficulty of the field: the lack of a universal low energy effective theory description of the high-$T_{c}$ phenomenology beyond the Landau paradigm. Recent experiments imply that the dualism between the local moment and the itinerant quasiparticle character of the electron in the high-$T_{c}$ cuprates may serve as an organizing principle to go beyond the Landau paradigm and may hold the key to the mystery of the pseudogap phenomena and the strange metal behavior.

description: In holographic models of gauge theories with matter, there generically exists a first order phase transition in which mesons dissociate. We perform a careful analysis of the meson and quasi-particle spectra in the overheated resp. undercooled regimes close to the junction of the two phases. We show that all overheated finite meson masses eventually become infinitely degenerate, which implies that any connection to the quasi-particle spectrum is more subtle than previously suggested. For the Sakai-Sugimoto model no smooth connection between these spectra is possible.

description: We study a general set of models of social network evolution and dynamics. The models consist of both a dynamics on the network and evolution of the network. Links are formed preferentially between 'similar' nodes, where the similarity is defined by the particular process taking place on the network. The interplay between the two processes produces phase transitions and hysteresis, as seen using numerical simulations for three specific processes. We obtain analytic results using mean field approximations, and for a particular case we derive an exact solution for the network. In common with real-world social networks, we find coexistence of high and low connectivity phases and history dependence.

description: The spacetime of a boosted Bondi-Sachs rotating black hole is considered as a proper background to examine electromagnetic configurations connected to analytic solutions of Maxwell equations. In our analysis, we first use the Bondi-Sachs transformations in order to bring the boosted rotating black hole metric into the Kerr-Schild form, from which zero angular momentum observers (ZAMOs) are constructed via the ADM formalism. In Kerr-Schild coordinates we obtain the Killing fields as sources of Maxwell electrodynamics, and we fix a ZAMO in order to evaluate the components of the electric and magnetic fields, from which we obtain nonsingular patterns of an eventual momentum-energy emission of a boosted Kerr-Schild black hole. Distinct patterns are examined and discussed in the case of variations of the boost parameter $γ$. We extend our analysis by considering the nonsingular electromagnetic emission in the framework of a boosted Bondi-Sachs rotating black hole, as it moves at relativistic speeds. We also discuss possible mechanisms that may resemble magnetospheres of rotating boosted black holes and give rise to hydromagnetic flows from accretion discs and to the production of jets.

description: We propose a simple unconventional geometric scenario to achieve a kind of nontrivial multi-qubit operations with superconducting charge qubits placed in a microwave cavity. The proposed quantum operations are insensitive not only to the thermal state of cavity mode but also to certain random operation errors, and thus may lead to high-fidelity quantum information processing. Executing the designated quantum operations, a class of highly entangled cluster states may be generated efficiently in the present scalable solid-state system, enabling one to achieve one-way quantum computation.

Musical Meaning for the Few: Instances of Private Reception in the Music of Brahms
Creators: name: Parmer, Dillon R.
Publisher: name: Current Musicology
Year: 2007

description: The received view of Brahms as a champion of “absolute” music has dominated the scholarly reception of his compositional output for over a century, and with good reason. Except in a few early works, Brahms rarely published his instrumental music with any of the suggestive clues that his contemporaries used in their program music, while his preference for the apparently more classical genres, forms, and procedures seems to distance him from the overtly progressive tendencies of Romanticism that eschewed reliance on classical conventions. What transpired in purely musical terms also was evident in the written word, both that of Brahms and of others. In what follows, I steer a middle ground by arguing that Brahms’s music has a double reception history: within his circle of intimates, Brahms often transmitted suggestive, even programmatic, clues but in the public sphere, he refrained from stipulating any such clues whatsoever, thereby distancing the same music from the more openly specified extramusical associations that characterized program music in the latter half of the nineteenth century. What emerges in this compromise is a hitherto unacknowledged species of music that exists simultaneously in two contrary ways: as program music for those to whom Brahms stipulated suggestive titles, poetic mottoes, or actual literary texts; as “abstract” or “absolute” music for everyone else.

Creators: name: Boynton, Susan
Publisher: name: Current Musicology
Year: 2007

description: Mary O’Neill’s book makes a valuable contribution to our understanding of an important monophonic repertory that has received relatively little attention from musicologists, despite its preservation in numerous manuscripts. The reasons for this neglect are well known: scholarship on the music of the trouvères has generally addressed their songs alongside or in relation to those of the troubadours. Consequently, the trouvère corpus is often viewed through the lens of a historiography that typically privileges the troubadours because of their chronological priority, casting the trouvères as derivative imitators. O’Neill seeks to understand the trouvères on their own terms. Given the wealth of melodies in medieval manuscripts of trouvère poetry (many in multiple versions), a monograph in English devoted entirely to the music of the trouvères is long overdue, particularly when considering that many of the new perspectives on genre, voice, orality, gender, sexuality, and performance in Old French lyric poetry have come from scholars of literature. O’Neill’s study may not satisfy all expectations-at 226 pages including bibliography and indices, it is a slim volume for such a vast subject-but the analyses in Courtly Love Songs offer many insights into the structures and forms of trouvère song and provide ample material for further reflection.

Policy learning

description: Approximately 6.1 million Americans have currently lost their right to vote due to a felon disenfranchisement law (FDL). Forty-eight states participate in this punitive practice but vary in their level of restriction. This report explores the reasons for this variability by analyzing the diffusion of FDL, its transformation, and the growth of less restrictive versions over time. It uses policy diffusion as a theoretical lens to test for the role of internal determinants and external mechanisms driving the diffusion of less restrictive FDL. To further understand this policy shift, this report also examines the policy history of states with policy reversals and specifically discusses recent policy changes in multiple states. We conclude this report with key findings and the role of public opinion in further research.

description: We study the fully nonlinear dynamics of black hole spontaneous scalarizations in Einstein-Maxwell scalar theory with coupling function $f(ϕ)=e^{-bϕ^{2}}$, which can transform usual Reissner-Nordström Anti-de Sitter (RN-AdS) black holes into hairy black holes. Fixing the Arnowitt-Deser-Misner mass of the system, the initial scalar perturbation will destroy the original RN-AdS black hole and turn it into a hairy black hole provided that the constant $-b$ in the coupling function and the charge of the original black hole are sufficiently large, while the cosmological constant is small enough. In the scalarization process, we observe that the black hole irreducible mass initially increases exponentially, then it approaches to and finally saturates at a finite value. Choosing stronger coupling and larger black hole charge, we find that the black hole mass exponentially grows earlier and it takes a longer time for a hairy black hole to be developed and stabilized. We further examine phase structure properties in the scalarization process and confirm the observations in the non-linear dynamical study.

description: Consider a model of particles (nucleons) which has a two-body interaction which leads to bound composites with saturation properties. These properties are : all composites have the same density and the ground state energies of composites with k nucleons are given by -kW+σk^{2/3} where W and σare positive constants. W represents a volume term and σa surface tension term. These values are taken from nuclear physics. We show that in the large N limit where N is the number of particles such an assembly in a large enclosure at finite temperature shows properties of liquid-gas phase transition. We do not use the two-body interaction but the gross properties of the composites only. We show that (a) the p-ρisotherms show a region where pressure does not change as $ρ$ changes just as in Maxwell construction of a Van der Waals gas, (b) in this region the chemical potential does not change and (c) the model obeys the celebrated Clausius-Clapeyron relations. A scaling law for the yields of composites emerges. For a finite number of particles N (upto some thousands) the problem can be easily solved on a computer. This allows us to study finite particle number effects which modify phase transition effects. The model is calculationally simple. Monte-Carlo simulations are not needed.

description: On the surface, Armida seems to project binary oppositions. The opera features a brave European hero, Rinald (whose name represents the Czech version of the more familiar “Rinaldo”). Rinald intrudes, together with his fellow crusaders, into the mysterious kingdom of the Syrian King Hydraot during their campaign to liberate Jerusalem. Rinald endangers the war plans of the crusaders by falling love with Hydraot’s daughter Armida, and , as a result, he has to fight the brutal magician Ismen. At the end of the opera, Rinald and the crusaders overcome their Muslim opponents and continue their (colonizing) campaign in Syria. A closer consideration of the opera’s libretto and music reveals the distinction between the European crusaders and Muslims is not straightforward as a simple Us/Them dichotomy would prescribe-a fact that several writers have commented upon.

description: In the area of customer support, understanding customers' intents is a crucial step. Machine learning plays a vital role in this type of intent classification. In reality, it is typical to collect confirmation from customer support representatives (CSRs) regarding the intent prediction, though it can unnecessarily incur prohibitive cost to ask CSRs to assign existing or new intents to the mis-classified cases. Apart from the confirmed cases with and without intent labels, there can be a number of cases with no human curation. This data composition (Positives + Unlabeled + multiclass Negatives) creates unique challenges for model development. In response to that, we propose a semi-supervised multi-task learning paradigm. In this manuscript, we share our experience in building text-based intent classification models for a customer support service on an E-commerce website. We improve the performance significantly by evolving the model from multiclass classification to semi-supervised multi-task learning by leveraging the negative cases, domain- and task-adaptively pretrained ALBERT on customer contact texts, and a number of un-curated data with no labels. In the evaluation, the final model boosts the average AUC ROC by almost 20 points compared to the baseline finetuned multiclass classification ALBERT model.

description: Nei primi due decenni del Novecento si diffonde anche in Italia uno stile espressionista, in cui le icone sintetiche del Simbolismo sono sottoposte a un trattamento brutale che elimina richiami ultra-terreni a favore di “visioni” crude e immanenti,  caratterizzate da una ripresa sistematica del passato italiano. Questo “Primitivismo” si attua anche grazie a una potente “deformazione”, soprattutto in Toscana. La “linea sintetica” dell’arte toscana evidenzia il rapporto che lega gli artisti del periodo ai predecessori Macchiaioli, soffermandosi sui alcuni protagonisti (Lorenzo Viani, Spartaco Carlini, Moses Levy, Amedeo Modigliani), fino agli sconfinamenti regressivi nel mondo popolare ed infantile  che nel caso di Alberto Magri diventa un vero e proprio “primitivismo candido”, collegato idealmente alla pittura premoderna del Duecento, del Trecento e del primo Quattrocento. Infine il caso di Osvaldo Licini, analizzato nelle prime due fasi della sua carriera che l’artista stesso schematicamente definì Primitivismo fantastico (1913-1915) ed Episodi di guerra (1915-1920).
Educational drama : one teacher's search for significance
Creators: name: Jardine, Laurie
Publisher: name: University of British Columbia

description: This study describes the journey of one teacher and her students through a year of change in thinking about, planning and implementing the secondary drama program. The change occurred as a result of a six-week summer course which I took in 1990, with leading drama theorist, Gavin Bolton. In September, 1990, I began to use the methodology and theory presented by Bolton in my own secondary drama program for Grade Eight, Nine and Ten students. The data for the study came from the student journals, teacher/ researcher observation, interviews, samples of student writing-in-role and post-unit evaluative strategies collected throughout this year of transition. The results indicate that the change of methodology had an impact on the perceived learning outcomes for both students and teacher. As well, strong evidence surfaced to support my belief that teaching drama in this manner has benefits which may not be easily achieved by other means. This study was written for teachers and students in the belief that both may find a more significant learning experience through the use of educational drama.

description: We calculate the microstates free entropy dimension of natural generators in an amalgamated free product of certain von Neumann algebras, with amalgamation over a hyperfinite subalgebra. In particular, some `exotic' Popa algebra generators of free group factors are shown to have the expected free entropy dimension. We also show that microstates and non--microstates free entropy dimension agree for generating sets of many groups. In the appendix by Wolfgang Lueck, the first L^2-Betti number for certain amalgamated free products of groups is calculated.
description: The second revised version significantly generalized the main result of the original one, (see the abstract) and contains a new appendix by Wolfgang Lueck. The third and fourth revisions correct some minor mistakes. The fifth version adds a result about embeddability of amalgmated free products
Noncommutative-geometry wormholes with isotropic pressure

description: The strategy adopted in the original Morris-Thorne wormhole was to retain complete control over the geometry at the expense of certain engineering considerations. The purpose of this paper is to obtain several complete wormhole solutions by assuming a noncommutative-geometry background with a concomitant isotropic-pressure condition. This condition allows us to consider a cosmological setting with a perfect-fluid equation of state. An extended form of the equation generalizes the first solution and subsequently leads to the generalized Chaplygin-gas model and hence to a third solution. The solutions obtained extend several previous results. This paper also reiterates the need for a noncommutative-geometry background to account for the enormous radial tension that is characteristic of Morris-Thorne wormholes.

description: The increase in aquaculture operations worldwide has provided new opportunities for the transmission of aquatic viruses. The occurrence of viral diseases remains a significant limiting factor in aquaculture production and for the sustainability. The ability to identify quickly the presence/absence of a pathogenic organism in fish would have significant advantages for the aquaculture systems. Several molecular methods have found successful application in fish pathology both for confirmatory diagnosis of overt diseases and for detection of asymptomatic infections. However, a lot of different variants occur among fish host species and virus strains and consequently specific methods need to be developed and optimized for each pathogen and often also for each host species. The first chapter of this PhD thesis presents a complete description of the major viruses that infect fish and provides a relevant information regarding the most common methods and emerging technologies for the molecular diagnosis of viral diseases of fish. The development and application of a real time PCR assay for the detection and quantification of lymphocystivirus was described in the second chapter. It showed to be highly sensitive, specific, reproducible and versatile for the detection and quantitation of lymphocystivirus. The use of this technique can find multiple application such as asymptomatic carrier detection or pathogenesis studies of different LCDV strains. The third chapter, a multiplex RT-PCR (mRT-PCR) assay was developed for the simultaneous detection of viral haemorrhagic septicaemia (VHS), infectious haematopoietic necrosis (IHN), infectious pancreatic necrosis (IPN) and sleeping disease (SD) in a single assay. This method was able to efficiently detect the viral RNA in tissue samples, showing the presence of single infections and co-infections in rainbow trout samples. The mRT-PCR method was revealed to be an accurate and fast method to support traditional diagnostic techniques in the diagnosis of major viral diseases of rainbow trout.
Analysis, Performance, and Images of Musical Sound: Surfaces, Cyclical Relationships and the Musical Work

description: In this paper we hope to reinscribe the familiar musicological concepts of analysis and performance, drawing them into new relationships, in order to turn them against their presuppositions and produce new configurations. Though an exploration of analysis, performance and images of musical sound, these new configurations highlight surface details and offer a alternative approach to previous analysis and performance paradigms, leading to a reformulation of the concept of musical “work”. In order to focus our argument we define “analysis” as the methodological activity of analyzing a score as practiced in most Western art music analytical journals published today. Likewise, while the concept of musical performance can encompass improvisation and physical gesture, we take “performance” to mean the Western art music performance tradition, as practiced today, of score interpretation. Although both definitions are admittedly limited, they represent typical approaches and activities within both fields.

description: Abstract

The promotion carried out by Holywings in the religious community is a promotional strategy that carries a big risk considering that the majority of Indonesian people are Muslims where liquor is an unlawful item. This was considered a violation and sparked various reactions in society. In the digital era, data sourced from social media is important data to understand the response of the Indonesian people to the violation of the Holywings issue. The research method used is explorative because marketing communication research based on social media data is still new. The research method is descriptive and quantitative by describing variables such as user volume, reach, conversation trends, top tweets, sentiments, influencers, and communication networks between social media users. The research sample uses the period from 23 June 2022 to 30 June 2022. The results of this research indicate that the issue of the Holywings violation is viral compared to other issues. The scope of the issue of violations at Café Holywings spreads throughout Indonesia and is dominant in DKI Jakarta Province. Even though Bali is the biggest branch of Café Holywings, there was very little reaction to the violation of Café Holywings. This is following the theory of expectation violations that the size of the violation reaction on social media is highly dependent on individual characteristics, context, and reaction.

description: We briefly report on our recent results regarding the introduction of a notion of a q-quaternion and the construction of instanton solutions of a would-be deformed su(2) Yang-Mills theory on the corresponding SO_q(4)-covariant quantum space. As the solutions depend on some noncommuting parameters, this indicates that the moduli space of a complete theory will be a noncommutative manifold.

description: We present a photometric and kinematical analysis of two and poorly studied open clusters; Koposov 12 (FSR 802) and Koposov 43 (FSR 848) by using cross-matched data from PPMXL and Gaia DR2 catalog. We use astrometric parameters to identify 285 and 310 cluster members for Koposov 12 and Koposov 43, respectively. Using the extracted member candidates and isochrone fitting to near-infrared (J, H, Ks) and Gaia DR2 bands (G, GBP, GRP), and Color Magnitude Diagrams (CMDs), we have estimated ages: log (age/yr) = 9.00 +/- 0.20 and 9.50 +/- 0.20, and distances d = 1850 +/- 43 pc and 2500 +/- 50 pc for Koposov 12 and Koposov 43, respectively, assuming Solar metallicity (Z=0.019). The estimated masses of the cluster derived using initial mass function and synthetic CMD are 364 +/- 19 M_sun and 352 +/- 19 M_sun. We have also computed their velocity ellipsoid parameters based on (3x3) matrix elements (mu_ij).
