description: Online property business or known as e-commerce is currently experiencing an increase in home sales. Indonesia's e-commerce property business has positive trending shown by the increasing sales of more than 500% from 2011 to 2015. A prediction of the property price is important to help investors or the public to have accurate information before buying property. One of the methods for prediction is a classification based on several distinctive property industry attributes, such as building size, land size, number of rooms, and location. Today, data is easily obtained, there are many open data from E-commerce sites. E-commerce contains information about homes and other properties advertised to sell. People also regularly visit the site to find the right property or to sell the property using price information which collectively available as open data. To predict the property sales, this research employed two different classification methods in Data Mining which are Decision Tree and k-NN classification. We compare which model classification is better to predict property price and their attributes. We use Indonesia's biggest property-based e-commerce site Rumah123.com as our open data source, and choose location Bandung in our experiment. The accuracy result of the decision tree is 75% and KNN is 71%, other than that k-NN can explore more data patterns than the Decision Tree.

description: Ultra-compact X-ray binaries (UCXBs) are low-mass X-ray binaries with hydrogen-deficient mass-donors and ultra-short orbital periods. They have been suggested to be the potential Laser Interferometer Space Antenna (LISA) sources in the low-frequency region. Several channels for the formation of UCXBs have been proposed so far. In this article, we carried out a systematic study on the He star donor channel, in which a neutron star (NS) accretes matter from a He main-sequence star through Roche-lobe overflow, where the mass-transfer is driven by gravitational wave radiation. Firstly, we followed the long-term evolution of the NS+He main-sequence star binaries by employing the stellar evolution code Modules for Experiments in Stellar Astrophysics, and thereby obtained the initial parameter spaces for the production of UCXBs. We then used these results to perform a detailed binary population synthesis approach to obtain the Galactic rates of UCXBs through this channel. We estimate the Galactic rates of UCXBs appearing as LISA sources to be $\sim3.1-11.9\, \rm Myr^{-1}$ through this channel, and the number of such UCXB-LISA sources in the Galaxy can reach about $1-26$ calibrated by observations. The present work indicates that the He star donor channel may contribute significantly to the Galactic UCXB formation rate. We found that the evolutionary tracks of UCXBs through this channel can account for the location of the five transient sources with relatively long orbital periods quite well. We also found that such UCXBs can be identified by their locations in the mass-transfer rate versus the orbital period diagram.

description: We investigate a reversible polymerization process in which individual polymers aggregate and fragment at a rate proportional to their molecular weight. We find a nonequilibrium phase transition despite the fact that the dynamics are perfectly reversible. When the strength of the fragmentation process exceeds a critical threshold, the system reaches a thermodynamic steady state where the total number of polymers is proportional to the system size. The polymer length distribution has a sharp exponential tail in this case. When the strength of the fragmentation process falls below the critical threshold, the steady state becomes non-thermodynamic as the total number of polymers grows sub-linearly with the system size. Moreover, the length distribution has an algebraic tail and the characteristic exponent varies continuously with the fragmentation rate.

description: We publish the Keck/HIRES and Keck/ESI spectra that we have obtained during the first 10 years of Keck observatory operations. Our full sample includes 42 HIRES spectra and 39 ESI spectra along 65 unique sightlines providing abundance measurements on ~85 damped Lya systems. The normalized data can be downloaded from the journal or from our supporting website: http://www.ucolick.org/~xavier/DLA/. The database includes all of the sightlines that have been included in our papers on the chemical abundances, kinematics, and metallicities of the damped Lya systems. This data has also been used to argue for variations in the fine-structure constant. We present new chemical abundance measurements for 10 damped Lya systems and a summary table of high-resolution metallicity measurements (including values from the literature) for 153 damped Lya systems at z>1.6. We caution, however, that this metallicity sample (and all previous ones) is biased to higher N(HI) values than a random sample.

description: In this paper the impact of the strength of hyperon-nucleon and hyperon-hyperon on the maximum neutron star mass is shown. The strong hyperon-hyperon coupling constant together with the additional nonlinear meson interaction terms lead to the essential softening of the equation of state and to the existence of another more compact branch of stable neutron star configurations. The analysis of the mass-radius relations leads to the conclusion that the additional stable configurations of hyperon-rich neutron stars are characterized by the reduced value of radii.

description: Motivated by recent experiments on colloidal systems with competing attractive and repulsive interactions, we simulate a two-dimensional system of colloids with competing interactions that can undergo fragmentation. In the absence of any other confining potential, the colloids can form stable clusters depending on the strength of the short range attractive term. By suddenly changing the strength of one of the interaction terms we find a rich variety of fragmentation behavior which is affected by the existence of "magic" cluster numbers. Such soft matter systems can be used to construct artificial nuclei.

description: We study the radiative energy loss of hard partons in a soft medium in the multiple soft scattering approximation. The soft medium is described by a 3D hydrodynamical model and we treat the averaging over all possible parton paths through the medium without approximation. While the nuclear suppression factor $R_{AA}$ does not reflect the high quality of the medium description (except in a reduced systematic uncertainty in extracting the quenching power of the medium), the hydrodynamical model also allows to study different centralities and in particular the angular variation of $R_{AA}$ with respect to the reaction plane, allowing for a controlled variation of the in-medium path-length. We study the angular dependence of $R_{AA}$ for different centralities, discuss the influence of hydrodynamical expansion and flow and comment on the comparison with preliminary data.

description: Within the framework of the $s$-$d(f)$ exchange model in the mean-field approximation for square, simple cubic, body-centered and face-centered cubic lattices, the formation of a ferromagnetic, spiral, and commensurate antiferromagnetic order is investigated. The possibility of the formation of inhomogeneous states (magnetic phase separation), which necessarily arises during first-order phase transitions in the electron filling parameter, is taken into account. The saturation of the antiferromagnetic and spiral states is studied depending on the parameters of the model. The results obtained include a rich variety of magnetic structures and phase transitions, allowing the interpretation of magnetic properties of semiconducting and metallic systems containing magnetic atoms.

An Efficient and Accurate Grid Method for Solving the Time-Dependent Schroedinger Equation: Application of Coulomb Wave Function DVR to Atomic Systems in Strong Laser Fields

description: We present an efficient and accurate grid method for solving the time-dependent Schrödinger equation of atomic systems interacting with intense laser pulses. As usual, the angular part of the wave function is expanded in terms of spherical harmonics. Instead of the usual finite difference (FD) scheme, the radial coordinate is discretized using the discrete variable representation which is constructed from the Coulomb wave function. For an accurate description of the ionization dynamics of atomic systems, the Coulomb wave function discrete variable representation (CWDVR) method needs 3-10 times less grid points than the FD method. The resultant grid points of CWDVR distribute unevenly so that one has finer grid near the origin and coarser one at larger distances. The other important advantage of the CWDVR method is that it treats the Coulomb singularity accurately and gives a good representation of continuum wave functions. The time propagation of the wave function is implemented using the well-known Arnoldi method. As examples, the present method is applied to the multiphoton ionization of both H and H$^-$ in intense laser fields. Short-time excitation and ionization dynamics of H by static electric fields is also investigated. For a wide range of photon energies and laser intensities, ionization rates calculated using this method are in excellent agreement with those from other theoretical calculations.

description: In this paper, we study the general form of three-point functions of conserved current multiplets $S_{α(k)}= S_{(α_1 \dots α_k)}$ of arbitrary rank in four-dimensional ${\mathcal N}=1$ superconformal theory. We find that the correlation function of three such operators $\langle \bar{S}_{\dotα(k)} (z_1) S_{β(k+l)} (z_2) \bar{S}_{\dotγ(l)} (z_3) \rangle$ is fixed by the superconformal symmetry up to a single complex coefficient though the precise form of the correlator depends on the values of $k$ and $l$. In addition, we present the general structure of mixed correlators of the form $\langle \bar{S}_{\dotα(k)} (z_1) S_{α(k)} (z_2) L(z_3) \rangle$ and $\langle \bar{S}_{\dotα(k)} (z_1) S_{α(k)} (z_2) J_{γ\dotγ} (z_3) \rangle$, where $L$ is the flavour current multiplet and $J_{γ\dotγ}$ is the supercurrent.

Η επιχειρηματική απόδοση, μετρήθηκε με βάση ερωτηματολόγια που εστάλησαν σε επιχειρηματίες-επιχειρήσεις. Τα ερωτηματολόγια περιείχαν ερωτήσεις με ποιοτικά χαρακτηριστικά της απόδοσης των επιχειρήσεων για τα τελευταία χρόνια της οικονομικής κρίσης. Τα αποτελέσματα ταξινομήθηκαν ανάλογα με την νομική μορφή τους και η επιμέρους ανάλυση επικεντρώθηκε στην έρευνα της σύνδεσης μεταξύ της νομικής μορφής τους και της απόδοσης. Η μέχρι τώρα βιβλιογραφία δεν είχε εντοπίσει άμεση σύνδεση μεταξύ της νομικής μορφής και της επιχειρηματικής απόδοσης, ως εκ τούτου τα ευρήματα της παρούσας έρευνας ήταν αναμενόμενα. Σημαντικός περιορισμός στην παρούσα έρευνα, αποτέλεσε το μικρό ποσοστό απόκρισης που οδήγησε σε δείγμα που δεν είχε ικανό αριθμό αποκρίσεων ανά νομική μορφή.

description: The present study attempts to find the relationship between legal entity types available in the Greek legal system and business performance. The crisis which the Greek economy has been going through the past years has made it infinitely more important to find the optimal legal entity to engage in business activity in Greece. Business performance was measured via questionnaires sent to businesspersons and business entities. Respondents were required to answer qualitative questions regarding performance of their business during the years of the economic crisis. The results were then taxonomized according to legal form of the entity and further analysis focused on finding a connection between legal form and business performance. Available research and bibliography have not so far been able to find a connection between business performance and the choice of legal entity, therefore the results of the study were expected. However, an important limitation to this study was the low response rate which led to a small sample per legal type. The present study contributes to the bibliography and research that has been thus far completed, as far as the data that has been collected by businesspersons-businesses which has led to the result that there is no direct connection between business performance and legal entity type

description: In the context of modern marketing, Twitter is considered a communication platform to spread information. Many companies create and acquire several Twitter accounts to support and perform varieties of marketing mix activities. Initially, each accounts used to capture a specific market profile. Together, the accounts create a network of information that provide consumer to the information they need depends on their contextual utilization. From many accounts available, we have the fundamental question on how to measure the influence of each account in the market based not only on their relations but also on the effects of their postings. The magnitude of Influence (MOI) metric is adapted together with Influence Rank (IR) measurement of accounts in their social network neighborhood. We use social network analysis approach to analyze 65 accounts in the social network of an Indonesian mobile phone network operator, Telkomsel which involved in marketing communications mix activities through series of related tweets. Using social network provide the idea of the activity in building and maintaining relationships with the target audience. This paper shows the results of the most potential accounts based on the network structure and engagement. Based on this research, the more number of followers one account has, the more responsibility it has to generate the interaction from their followers in order to achieve the expected effectiveness. The focus of this paper is to determine the most potential accounts in the application of marketing communications mix in Twitter.

description: The distribution of visual interstellar extinction $A_V$ has been mapped in selected areas over the Northern sky, using available LAMOST DR5 and Gaia DR2/EDR3 data. $A_V$ was modelled as a barometric function of galactic latitude and distance. The function parameters were then approximated by spherical harmonics. The resulting analytical tridimensional model of the interstellar extinction can be used to predict $A_V$ values for stars with known parallaxes, as well as the total Galactic extinction in a given location in the sky.

On topological recursion for Wilson loops in $\mathcal N=4$ SYM at strong coupling

Year: 2021
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We consider $U(N)$ $\mathcal N=4$ super Yang-Mills theory and discuss how to extract the strong coupling limit of non-planar corrections to observables involving the $\frac{1}{2}$-BPS Wilson loop. Our approach is based on a suitable saddle point treatment of the Eynard-Orantin topological recursion in the Gaussian matrix model. Working directly at strong coupling we avoid the usual procedure of first computing observables at finite planar coupling $λ$, order by order in $1/N$, and then taking the $λ\gg 1$ limit. In the proposed approach, matrix model multi-point resolvents take a simplified form and some structures of the genus expansion, hardly visible at low order, may be identified and rigorously proved. As a sample application, we consider the expectation value of multiple coincident circular supersymmetric Wilson loops as well as their correlator with single trace chiral operators. For these quantities we provide novel results about the structure of their genus expansion at large tension, generalising recent results in arXiv:2011.02885.

Observing quantum non-locality in the entanglement between modes of massive particles

description: We consider the question of whether it is possible to use the entanglement between spatially separated modes of massive particles to observe nonlocal quantum correlations. Mode entanglement can be obtained using a single particle, indicating that it requires careful consideration before concluding whether experimental observation, e.g. violation of Bell inequalities, is possible or not. In the simplest setups analogous to optics experiments, that observation is prohibited by fundamental conservation laws. However, we show that using auxiliary particles, mode entanglement can be converted into forms that allow the observation of quantum non-locality. The probability of successful conversion depends on the nature and number of auxiliary particles used. In particular, we find that an auxiliary Bose-Einstein condensate allows the conversion arbitrarily many times with a small error that depends only on the initial state of the condensate.

An integrated approach to programming and performance modeling of multicomputers
Creators: name: Sreekantaswamy, Halsur V.
Publisher: name: University of British Columbia
Year: 2009

description: The relative ease with which it is possible to build inexpensive, high-performance multicomputers using regular microprocessors has made them very popular in the last decade. The major problem with multicomputers is the difficulty in effectively programming them. Programmers are often faced with the choice of using high level programming tools that are easy to use but provide poor performance or low level tools that take advantage of specific hardware characteristics to obtain better performance but are difficult to use. In general, existing parallel programming environments do not provide any guarantee of performance and they provide little support for performance evaluation and tuning. This dissertation explores an approach in which users are provided with programming support based on parallel programming paradigms. We have studied two commonly used parallel programming paradigms: Processor Farm and Divide-and-Conquer. Two runtime systems, Pfarm and TrEK, were designed and developed for applications that fit these paradigms. These systems hide the underlying complexities of multicomputers from the users, and are easy-to-use and topology independent. Performance models are derived for these systems, taking into account the computation and communication characteristics of the applications in addition to the characteristics of the hardware and software system. The models were experimentally validated on a large transputer-based system. The models are accurate and proved useful for performance prediction and tuning. Pfarm and TrEK were integrated into Parsec, a programming environment that supports program development and execution tools such as a graphical interface, mapper, loader and debugger. They have also been used to develop several image processing and numerical analysis applications.

description: We present a revised measurement of the optical extragalactic background light (EBL), based on the contribution of resolved galaxies to the integrated galaxy light (IGL). The cosmic optical background radiation (COB), encodes the light generated by star-formation, and provides a wealth of information about the cosmic star formation history (CSFH). We combine wide and deep galaxy number counts from the Galaxy And Mass Assembly survey (GAMA) and Deep Extragalactic VIsible Legacy Survey (DEVILS), along with the Hubble Space Telescope (HST) archive and other deep survey datasets, in 9 multi-wavelength filters to measure the COB in the range from 0.35 micron to 2.2 micron. We derive the luminosity density in each band independently and show good agreement with recent and complementary estimates of the optical-EBL from very high-energy (VHE) experiments. Our error analysis suggests that the IGL and Gamma-ray measurements are now fully consistent to within ~10%, suggesting little need for any additional source of diffuse light beyond the known galaxy population. We use our revised IGL measurements to constrain the cosmic star-formation history, and place amplitude constraints on a number of recent estimates. As a consistency check, we can now demonstrate convincingly, that the CSFH, stellar mass growth, and the optical-EBL provide a fully consistent picture of galaxy evolution. We conclude that the peak of star-formation rate lies in the range 0.066-0.076 Msol/yr/Mpc^3 at a lookback time of 9.1 to 10.9 Gyrs.

Within Type IIA string theory with intersecting D6-branes, we spell out specific conditions for the emergence of such couplings and provide a class of supersymmetric local SU(5) Grand Unified models, based on the Z_2 x Z'_2 orientifold compactification, where perturbatively absent Dirac neutrino masses can be generated by D2-brane instantons in the experimentally observed mass regime, while Majorana masses remain absent, thus providing an intriguing mechanism for the origin of small neutrino masses due to non-perturbative stringy effects.

Dubravka Ugrešićs Romane "Des Alleinseins müde" und "Baba Jaga legt ein Ei" als Beispiele paradigmatischer, weiblicher Prosa

description: Diese Arbeit untersucht den Roman „Des Alleinseins müde“ und „Baba Jaga legt ein Ei“ von Dubravka Ugrešić unter den Gesichtspunkten der paradigmatischen, weiblichen Prosa. Dubravka Ugrešić definierte die paradigmatische, weibliche Prosa im Zuge einer literaturwissenschaftlichen Analyse weiblich geprägter, sowjetischer Prosa der 1960er und 1970er Jahre. Die paradigmatische, weibliche Prosa umfasst zwei maßgebliche Kriterien: Einerseits eine dem russischen Skaz ähnliche Erzählform und andererseits einen thematischen Fokus auf den Alltag von Frauen. Die Arbeit legt in einem ersten Schritt die Entwicklung des jugoslawischen Neofeminismus dar und erläutert dessen wichtigste ExponentInnen und Werke. Des Weiteren wird Dubravka Ugrešićs Schreiben im Kontext des jugoslawischen Neofeminismus behandelt. Es wird auf ihre Rolle hinsichtlich der Hexen von Rio Causa eingegangen und inwiefern sich dieses Ereignis auf ihr weiteres Schreiben auswirkte.

description: In this second paper, we pursue the analysis of the 180 ks XMM-Newton campaign towards the young open cluster NGC 6231 and we focus on its rich OB star population. We present a literature-based census of the OB stars in the field of view with more than one hundred objects, among which 30% can be associated with an X-ray source. All the O-type stars are detected in the X-ray domain as soft and reasonably strong emitters. In the 0.5-10.0 keV band, their X-ray luminosities scale with their bolometric luminosities as $\log L_\mathrm{X} - \log L_\mathrm{bol}=-6.912\pm0.153$. Such a scaling law holds in the soft (0.5-1.0 keV) and intermediate (1.0-2.5 keV) bands but breaks down in the hard band. While the two colliding wind binaries in our sample clearly deviate from this scheme, the remaining O-type objects show a very limited dispersion (40% or 20% according to whether `cool' dwarfs are included or not), much smaller than that obtained from previous studies. At our detection threshold and within our sample, the sole identified mechanism that produces significant modulations in the O star X-ray emission is related to wind interaction. The intrinsic X-ray emission of non-peculiar O-type stars seems thus constant for a given star and the level of its X-ray emission is accurately related to the its luminosity or, equivalently, to its wind properties. Among B-type stars, the detection rate is only about 25% in the sub-type range B0-B4 and remains mostly uniform throughout the different sub-populations while it drops significantly at later sub-types. The associated X-ray spectra are harder than those of O-type stars. Our analysis points towards the detected emission being associated with a physical PMS companion >...

New Calculations of Recombination Rates for Cold $^4$He Atoms and Determination of Universal Scaling Functions

description: Three-body recombination rates for cold $^4$He are calculated with a new method which exploits the simple relationship between the imaginary part of the atom-dimer elastic scattering phase shift and the $S$-matrix for recombination. The elastic phase shifts are computed above breakup threshold by solving a three-body Faddeev equation in momentum space with inputs based on a variety of modern atom-atom potentials. Recombination coefficients for the HFD-B3-FCII potential agree very well with the only previously published results. Since the elastic scattering and recombination processes for $^4$He are governed by "Efimov physics", they depend on universal functions of a scaling variable. The newly computed recombination coefficients for potentials other than HFD-B3-FCII make it possible to determine these universal functions for the first time.

description: We build a framework allowing for a systematic investigation of the issue: "Which quantum states are universal resources for one-way quantum computation?" We start by re-examining what is exactly meant by "universality" in quantum computation, and what the implications are for universal one-way quantum computation. Given the framework of a measurement-based quantum computer, where quantum information is processed by local operations only, the most general universal one-way quantum computer is one which is capable of accepting arbitrary classical inputs and producing arbitrary quantum outputs--we refer to this property as CQ-universality. We then show that a systematic study of CQ-universality in one-way quantum computation is possible by identifying entanglement features that must be present in every universal resource. These insights are used to identify several states as being not universal, such as 1D cluster states, W states, and ground states of non-critical 1D spin systems. Our criteria are strengthened by considering the efficiency of a quantum computation, and we find that entanglement measures must obey a certain scaling law with the system size for all efficient universal resources. This again leads to examples of non-universal resources, such as, e.g., ground states of critical 1D spin systems. We also provide several examples of efficient universal resources, namely graph states corresponding to hexagonal, triangular and Kagome lattices. Finally, we consider the more general notion of encoded CQ-universality, where quantum outputs are allowed to be produced in an encoded form. Again we provide entanglement-based criteria for encoded universality. Moreover, we present a general procedure to construct encoded universal resources.

Shifting the Universe: Early Dark Energy and Standard Rulers

description: The presence of dark energy at high redshift influences both the cosmic sound horizon and the distance to last scattering of the cosmic microwave background. We demonstrate that through the degeneracy in their ratio, early dark energy can lie hidden in the CMB temperature and polarization spectra, leading to an unrecognized shift in the sound horizon. If the sound horizon is then used as a standard ruler, as in baryon acoustic oscillations, then the derived cosmological parameters can be nontrivially biased. Fitting for the absolute ruler scale (just as supernovae must be fit for the absolute candle magnitude) removes the bias but decreases the leverage of the BAO technique by a factor 2.

Determining the complete spectrum for sparse symmetric matrices
Creators: name: Cavers, Ian Alfred
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation studies a restricted form of the fundamental algebraic eigenvalue prob lem. From the broad spectrum of eigenvalue problems and solution methods, it focuses upon sequential direct methods for determining moderately large subsets of eigenvalues or the complete spectrum of large sparse symmetric matrices. The thesis uses a combination of theoretical analysis and experimentation with symbolic and numeric implementations to develop generally applicable, reliable, efficient and accurate algorithms that are easily applied by novice and expert practitioners alike. This dissertation’s approach is to reexam- ine eigenvalue methods based on the similarity reduction of matrices to tridiagonal form, developing algorithms that more fully exploit matrix sparsity. Using specially developed sparse reduction tools, the thesis identifies the deficiencies and limitations of existing direct tridiagonalization methods, providing an improved un derstanding of the underlying fill characteristics of sparse reductions. The best previ ously published approach combines a bandwidth reducing preordering with Rutishauser and Schwarz’s O(bn2) band-preserving tridiagonalization algorithm. This approach places complete reliance upon the preordering to exploit sparsity, but it typically leaves the band of the matrix relatively sparse prior to reduction. The thesis presents several novel sparse reduction algorithms, including the hybrid tridiagonalization methods HYBBC and HYB SBC, that rearrange the elimination of nonzero entries to improve band sparsity utilization. HYBBC combines Bandwidth Contraction, a diagonally-oriented sparse reduction, with Rutishauser and Schwarz’s column-oriented tridiagonalization. For a wide range of 70 prac- tical sparse problems the new algorithm reduces CPU requirements by an average of 31%, with reductions as high as 63%. HYBSBC improves upon HYBBC’s successful techniques by substituting the novel Split Bandwidth Contraction algorithm for Bandwidth Contraction. The Split Bandwidth Contraction algorithm takes additional advantage of band sparsity to significantly improve the efficiency of partial bandwidth contractions. In addition, HYB- SBC employs the Z-transition strategy to precisely regulate the transition between its two reduction stages, permitting tridiagonalization in as little as 1/5 the time of Rutishauser and Schwarz. Finally, to demonstrate the relative efficiency of sparse tridiagonalization based eigenvalue methods, the thesis compares variants of the Lanczos algorithm to HYBSBC using theoretical analysis and experimentation with leading Lanczos codes.

description: We study the gravitational description of conformal half-BPS domain wall operators in N=4 SYM, which are described by defect CFT's. These defect CFT's arise in the low energy limit of a Hanany-Witten like brane setup and are described in a probe brane approximation by a Karch-Randall brane configuration. The gravitational backreaction takes the five-branes in AdS_5xS^5 through a geometric transition and turns them into appropriate fluxes which are supported on non-trivial three-spheres.

description: We study the spectra of two-gluon glueballs and three-gluon oddballs and corresponding equation of state in $5$-dimensional deformed holographic QCD models in the graviton-dilaton system, where the metric, the dilaton field and dilaton potential are self-consistently solved from each other through the Einstein field equations and the equation of motion of the dilaton field. We compare the models by inputting the dilaton field, inputting the deformed metric and inputting the dilaton potential, and find that with only 2 parameters, the $5$-dimensional holographic QCD model predictions on glueballs/oddballs spectra in general are in good agreement with lattice results except two oddballs $0^{+-}$ and $2^{+-}$. From the results of glueballs/oddballs spectra at zero temperature and the equation of state at finite temperature, we observe that the model with quadratic dilaton field can simultaneously describe glueballs/oddballs spectra as well as equation of state of pure gluon system. The model with quadratic $A_{E}(z)$ can describe glueballs/oddballs spectra, but its corresponding equation of state behaves more like $N_{f}=2+1$ quark matter. These are consistent with dimension analysis at UV boundary.

description: The abundance of Li, Be, and B isotopes in galactic cosmic rays (GCR) between E=50-200 MeV/nucleon has been observed by the Cosmic Ray Isotope Spectrometer (CRIS) on NASA's ACE mission since 1997 with high statistical accuracy. Precise observations of Li, Be, B can be used to constrain GCR propagation models. \iffalse Precise observations of Li, Be, and B in addition to well-measured production cross-sections are used to further constrain GCR propagation models. \fi We find that a diffusive reacceleration model with parameters that best match CRIS results (e.g. B/C, Li/C, etc) are also consistent with other GCR observations. A $\sim$15--20% overproduction of Li and Be in the model predictions is attributed to uncertainties in the production cross-section data. The latter becomes a significant limitation to the study of rare GCR species that are generated predominantly via spallation.

description: A centralized access to sources, editions, and further kinds of publications facilitates the research process and provides a comprehensive overview of existing information. To connect musicological collections and repositories, we created a metasearch for annotated music: IncipitSearch. It is a tool and a service specifically tailored for research on music incipits, the initial sequences of notes that characterize a work. IncipitSearch is a service to interconnect musical pieces via metadata. It is also a tool that can be reintegrated into existing digital research platforms. By connecting some of the largest digital collections of music metadata it already offers access to around 1 million incipits. In four comprehensible steps, this poster will be a guide explaining how data owners can add their data to IncipitSearch and how the reimplementation of the search functionality can be carried out.
