Dante's Blood Elegies
Creators: name: Fritz-Morkin, Maggie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: “Tragice, sive comice, sive elegiace sint canenda” (treat [poetic subjects] in tragic, comic, or elegiac style) writes a mid-career Dante in De vulgari eloquentia 2.4.5–6 (ca. 1303–4).1 The poem challenges its readers’ notions of stylistic/genric categories quite explicitly, since Dante twice refers to his stylistically innovative work as “comedìa” (Inferno 16.128; Inf. 21.2) in clear contrast to the “alta . . . tragedia” (Inf. 20.113) of Virgil’s Aeneid Elegy, by contrast, is never named in the Commedia. Does this notable omission amount to a condemnation of the style? An assertion of its irrelevance to the project? Or is elegy simply too broad a category to bring to bear on a text where souls’ laments over death and loss are omnipresent? Readers have intuitively (and correctly, I believe) described some of the most sentimentally appealing speeches of the dead as “elegiac,” especially where the sweetness of memory sharpens the bitterness of present punishment.2 One task of this essay is to look closely at the definitions and theories of elegy informing Dante’s late engagement with the style in the Commedia. A significant amount of scholarship has already traced the influence of classical and medieval concepts of elegy—especially that which laments erotic frustration—on Dante’s early lyric, as well as on his metaliterary considerations in De vulgari eloquentia and Convivio.3 I will suggest that he revisits erotic elegy in the Francesca episode of Inferno 5. Illustrative of the moral hazards of courtly romance and stilnovist lyric, Francesca’s speech features some formal and thematic markers of erotic elegy, implying Dante’s condemnation of this genre as well. But while his critique of erotic elegy can be traced back to the Vita nova, in the Commedia he takes up a broader conception of elegy that is not [End Page 107] limited to lost love. I will argue that this more thorough and nuanced condemnation of elegy is one of Dante’s aims in presenting Pier della Vigna as a parody of Boethius, the elegist of record in Dante’s day.
Title Epidemic Model of a Concept within the Subject Classes of Patents: A Case Study on the Term RFID
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2016

description: The current research aims at studying the epidemic model of the term RFID within the classes of patents. Methodology: The research is descriptive and has been conducted based on the mathematical models of diseases. Research population consists of 35,627 granted patents from the USPTO database those which the terms RFID or Radio Frequency Identification occur in their titles or abstracts. Data analysis was performed through software like Excel, SPSS, and Ravar-Matrix. Findings show that the cumulative growth of sub-classes with the term RFID follows an S-logistic model. This is an evidence of natural growth rate for assigning the term RFID to the USPTO sub-classes over the years.  Other finding reveals that the term RFID has been entered into and exited from the sub-classes of patents like the SIS epidemic model of diseases. As a final conclusion, the most technical fields those that are susceptible for RFID technology, have been met this technology. On the base of SIS model, the epidemic of RFID technology has been reached a balance.
Poetry and Poetics in Gilles of Corbeil and Gentile da Foligno’s Carmina de urinarum iudiciis

Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Some medical treatises from medieval France and Italy demonstrate surprising rhetorical exuberance, especially in the paratexts where an authorial persona can emerge in the first person. This essay launches from the scatological metaphors and epithets in the exordia of works and commentaries by the physicians Archimattheus, Gilles of Corbeil, and Gentile da Foligno. In captationes benevolentiae styled after Ciceronian precepts, these authors attack their rivals before presenting their own superior science. Their scurrilous invectives—“Hoc salernitani cacantes sanitatem nominant!” (This is what the shitting Salernitans call health!); “discursores alienis fecibus imbuti” (vagrants steeped in other dreck)—tap into carnivalesque modes where excrement is organic, filthy, vituperative, and comic, in contrast to the sterility of the treatises’ technical, Scholastic discourse. A close reading of Gilles’s twelfth-century Carmina de urinarum iudiciis (Songs on Judging Urine) and Gentile’s fourteenth-century commentary on this verse treatise shows that both of these experts in uroscopy tie their excremental imagery into a nuanced poetics that extends from the paratexts into the heart of the work. Both writers demonstrate acute metaliterary sensibility, and respectable training in classical and medieval theories of rhetoric and poetry. Gilles defends his choice to write in verse through a constellation of metaphors pitting the synthetic clarity of both urine and poetry against the muddled confusion of feces and prose. He further ennobles his work by comparing the hermeneutics of uroscopy with allegorical interpretation. Gentile assumes the role of exegete, interpreting Gilles’s verses and unveiling their philosophical and theoretical underpinnings.

description: Stochastic simulations are often sensitive to the source of randomness that character-izes the statistical quality of their results. Consequently, we need highly reliable Random Number Generators (RNGs) to feed such applications. Recent developments try to shrink the computa-tion time by relying more and more General Purpose Graphics Processing Units (GP-GPUs) to speed-up stochastic simulations. Such devices bring new parallelization possibilities, but they also introduce new programming difficulties. Since RNGs are at the base of any stochastic simulation, they also need to be ported to GP-GPU. There is still a lack of well-designed implementations of quality-proven RNGs on GP-GPU platforms. In this paper, we introduce ShoveRand, a frame-work defining common rules to generate random numbers uniformly on GP-GPU. Our framework is designed to cope with any GPU-enabled development platform and to expose a straightfor-ward interface to users. We also provide an existing RNG implementation with this framework to demonstrate its efficiency in both development and ease of use.

description: Metal-poor dwarf galaxies in the local universe, such as those found in the RESOLVE galaxy survey, often produce high [O III]/Hβ ratios close to the star-forming demarcation lines of the diagnostic BPT diagram. Modelling the emission from these galaxies at lower metallicities generally underpredicts this line ratio, which is typically attributed to a deficit of photons >35 eV. We show that applying a model that includes empirical abundances scaled with metallicity strongly influences the thermal balance in HII regions and preserves the [O III]/Hβ offset even in the presence of a harder radiation field generated by interacting binaries. Additional heating mechanisms are more successful in addressing the offset. In accordance with the high sSFR typical of dwarf galaxies in the sample, we demonstrate that cosmic ray heating serves as one mechanism capable of aligning spectral synthesis predictions with observations. We also show that incorporating a range of physical conditions in our modelling can create even better agreement between model calculations and observed emission-line ratios. Together these results emphasize that both the hardness of the incident continuum and the variety of physical conditions present in nebular gas clouds must be accurately accounted for prior to drawing conclusions from emission-line diagnostic diagrams.

description: Since the discovery of the fullerene C60, many very interesting structures have been proposed, such as Ti8C12, Au20, Au32, Au42, TM@Sin, Eu@Si20, B80, and B_{40}^{-/0}. Here, an exceptionally stable hollow cage containing 20 scandiums and 60 carbons was identified. This Sc20C60 molecular cluster has a Th point group symmetry and a volleyball-like shape, that we refer to below as Volleyballene. Electronic structure analysis shows that the formation of delocalized π bonds between Sc atoms and neighboring five-membered carbon rings is crucial for stabilizing the cage structure. A relatively large HOMO-LUMO gap was found. The results of vibrational frequency analysis and molecular dynamics simulations also demonstrate that this Volleyballene molecule is exceptionally stable.

description: In this paper, we first address the space-time decay properties for higher order derivatives of strong solutions to the Boussinesq system in the usual Sobolev space. The decay rates obtained here are optimal. The proof is based on a parabolic interpolation inequality, bootstrap argument and some weighted estimates. Secondly, we present a new solution integration formula for the Boussinesq system, which will be employed to establish the existence of strong solutions in scaling invariant function spaces. We further investigate the asymptotic profiles and decay properties of these strong solutions. Our results recover and extend the important results in Brandolese and Schonbek (Tran. A. M.S.

description: Research Objective: Feasibility study of the Family and Women’s Studies Thesaurus considering the expansion of information in the field of women and family studies, as well as the wide span of related vocabulary and the development of vocabulary lists and bibliographies, the Family and Women’s Studies Thesaurus can be a professional tool for indexing and retrieval of women’s information in databases, library collections, archives and documentation centers as well as the Internet. Using this thesaurus, an indexing system will be developed which can be used for indexing, storage and retrieval of family and women’s databases.\n\nMethodology: The research method used in this study is documentary-based and the data gathering method was through library search in printed and electronic resources as well as interviewing professionals in the field of family and Women’s Studies. Through building a concept network between the terms, first the main structure of the thesaurus was determined using the inductive method and then the detailed structure was developed. Using this concept network, terms of the field were determined in a specific system and their interrelations were clarified.\n\nFindings: By studying resources including books, theses and articles in the field of women and family studies, and using ISO 25964-1 standard, the following 13 major categories were determined for the Family and Women’s Studies Thesaurus : 1. Religion; 2. Health and Hygiene; 3. Politics; 4. Economics; 5.Social Sciences; 6. Education; 7. Psychology; 8. History; 9. Culture and Literature; 10. International Relations; 11. Law; 12. Science and Technology; 13. Sports. There exists a rich vocabulary pool in the above categories; in fact around 6000 terms were identified.\n\nConclusion: Based upon the collected vocabulary and after building the references and scope notes, 243 keywords including 160 preferred terms, 124 related terms, 83 scope notes and 82 non-preferred terms were identified and entered into the Thesaurus Builder software. The alphabetical index, tree index, rotated index and the English-Persian index were developed as a model for the main thesaurus. As a result, the Family and Women’s Studies Thesaurus can be developed based upon the vocabulary and the model at hand.

description: The discovery around the turn of the millennium of a population of very massive (M* > 2 × 106 M☉) compact stellar systems (CSS) with physical properties (radius, velocity dispersion, stellar mass etc.) that are intermediate between those of the classical globular cluster (GC) population and galaxies led to questions about their exact nature. Recently a consensus has emerged that these objects, usually called ultracompact dwarfs (UCDs), are a mass-dependent mixture of high-mass star clusters and remnant nuclei of tidally disrupted galaxies. The existence of genuine star clusters with stellar masses >107 M☉ naturally leads to questions about the upper mass limit of the star cluster formation process. In this work we compile a comprehensive catalogue of CSS, and reinforce the evidence that the true ancient star cluster population has a maximum mass of M* ∼ 5 × 107 M☉, corresponding to a stellar mass at birth of close to 108 M☉. We then discuss several physical and statistical mechanisms potentially responsible for creating this limiting mass.

description: We study the X-ray properties of a sample of 14 optically-selected low-mass AGN whose masses lie within the range 1E5 -2E6 M(solar) with XMM-Newton. Only six of these low-mass AGN have previously been studied with sufficient quality X-ray data, thus, we more than double the number of low-mass AGN observed by XMM-Newton with the addition of our sample. We analyze their X-ray spectral properties and variability and compare the results to their more massive counterparts. The presence of a soft X-ray excess is detectable in all five objects which were not background dominated at 2-3 keV. Combined with previous studies, this gives a total of 8 low-mass AGN with a soft excess. The low-mass AGN exhibit rapid, short-term variability (hundreds to thousands of seconds) as well as long-term variability (months to years). There is a well-known anti-correlation between black hole mass and variability amplitude (normalized excess variance). Comparing our sample of low-mass AGN with this relation we find that all of our sample lie below an extrapolation of the linear relation. Such a flattening of the relation at low masses (below about 1E6 M(solar)) is expected if the variability in all AGN follows the same shape power spectrum with a break frequency that is dependent on mass. Finally, we also found two objects that show significant absorption in their X-ray spectrum, indicative of type 2 objects, although they are classified as type 1 AGN based on optical spectra.

description: We measure the environmental dependence, where environment is defined by the distance to the third nearest neighbor, of multiple galaxy properties inside the Environmental COntext (ECO) catalog. We focus primarily on void galaxies, which we define as the 10% of galaxies having the lowest local density. We compare the properties of void and non-void galaxies: baryonic mass, color, fractional stellar mass growth rate (FSMGR), morphology, and gas-to-stellar-mass ratio (estimated from a combination of H I data and photometric gas fractions calibrated with the REsolved Spectroscopy Of a Local VolumE survey). Our void galaxies typically have lower baryonic masses than galaxies in denser environments, and they display the properties expected of a lower mass population: they have more late types, are bluer, have a higher FSMGR, and are more gas-rich. We control for baryonic mass and investigate the extent to which void galaxies are different at fixed mass. Void galaxies are bluer, more gas-rich, and more star-forming at fixed mass than non-void galaxies, which is a possible signature of galaxy assembly bias. Furthermore, we show that these trends persist even at fixed mass and morphology, and we find that voids host a distinct population of early types that are bluer and more star-forming than the typical red and quenched early types. In addition to these empirical observational results, we also present theoretical results from mock catalogs with built-in galaxy assembly bias. We show that a simple matching of galaxy properties to (sub)halo properties, such as mass and age, can recover the observed environmental trends in ECO galaxies.
The Investigation of the Librarians’ Mental Model Completeness Scale of the Icons in the Circulation and Cataloging Modules of Azarakhsh, Simorgh and Nika Digital Library Applications
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2016

description: The present study intended to investigate the librarians’ mental model completeness scale of the icons in the circulation and cataloging modules of Azarakhsh, Simorgh and Nika digital library applications. Following a survey research design, The population of this research consisted of the librarians who were familiar with at least one of the digital library applications. Since the number of them was limited (174), they were selected using census. According to the results, in both circulation and cataloging modules, the librarians’ mental model of the icons was more complete in Simorgh application than those of Azarakhsh and Nika. Furthermore, a list of icons in the circulation and cataloging modules of the three applications, in which the librarians’ mental model of the icons’ functions was complete and incomplete, was provided. Since the users’ mental models of the icons in both circulation and cataloging modules might be incomplete or incorrect, one can determine the required instruction for the librarians by investigating the mental models’ completeness scale. Furthermore, providing a list of icons in which the librarians’ mental model of the icons’ functions is complete helps designers to design user interface in such a way that it corresponds to the users’ mental models as much as possible.

description: We consider the problem of extinction processes on random networks with a given structure. For sufficiently large well-mixed populations, the process of extinction of one or more state variable components occurs in the tail of the quasi-stationary probability distribution, thereby making it a rare event. Here we show how to extend the theory of large deviations to random networks to predict extinction times. In particular, we use the theory to find the most probable path leading to extinction. We apply the methodology to epidemic models and discover how mean extinction times scale with epidemiological and network parameters in Erdos-Renyi networks. The results are shown to compare quite well with Monte Carlo simulations of the network in predicting both the most probable paths to extinction and mean extinction times.

description: Existing star-forming vs. active galactic nucleus (AGN) classification schemes using optical emission-line diagnostics mostly fail for low-metallicity and/or highly star-forming galaxies, missing AGN in typical z ∼0 dwarfs. To recover AGN in dwarfs with strong emission lines (SELs), we present a classification scheme optimizing the use of existing optical diagnostics. We use Sloan Digital Sky Survey emission-line catalogs overlapping the volume- and mass-limited REsolved Spectroscopy Of a Local VolumE (RESOLVE) and Environmental COntex (ECO) surveys to determine the AGN percentage in SEL dwarfs. Our photoionization grids show that the [O iii]/Hβ versus [S ii]/Hα diagram (S ii plot) and [O iii]/Hβ versus [O i]/Hα diagram (O i plot) are less metallicity sensitive and more successful in identifying dwarf AGN than the popular [O iii]/Hβ versus [N ii]/Hα diagnostic (N ii plot or "BPT diagram"). We identify a new category of "star-forming AGN"(SF-AGN) classified as star-forming by the N ii plot but as AGN by the S ii and/or O i plots. Including SF-AGN, we find the z ∼0 AGN percentage in dwarfs with SELs to be 1/43%-16%, far exceeding most previous optical estimates (1/41%). The large range in our dwarf AGN percentage reflects differences in spectral fitting methodologies between catalogs. The highly complete nature of RESOLVE and ECO allows us to normalize strong emission-line galaxy statistics to the full galaxy population, reducing the dwarf AGN percentage to 1/40.6%-3.0%. The newly identified SF-AGN are mostly gas-rich dwarfs with halo mass <1011.5 M , where highly efficient cosmic gas accretion is expected. Almost all SF-AGN also have low metallicities (Z 2 0.4 Z ), demonstrating the advantage of our method.

description: The long awaited baryonic $B$ decay $\bar B{}^0\to p\bar p$ was recently observed by LHCb with a branching fraction of order $10^{-8}$. All the earlier model predictions are too large compared with experiment. In this work, we point out that for a given tree operator $O_i$, the contribution from its Fiertz transformed operator, an effect often missed in the literature, tends to cancel the internal $W$-emission amplitude induced from $O_i$. The wave function of low-lying baryons are symmetric in momenta and the quark flavor with the same chirality, but antisymmetric in color indices. Using these symmetry properties and the chiral structure of weak interactions, we find that half of the Feynman diagrams responsible for internal $W$-emission cancel. Since this feature holds in the charmless modes but not in the charmful ones, we advocate that the partial cancellation accounts for the smallness of the tree-dominated charmless two-body baryonic $B$ decays. This also explains why most previous model calculations predicted too large rates as the above consideration was not taken into account. Finally, we emphasize that, contrary to the claim in the literature, the internal $W$-emission tree amplitude should be proportional to the Wilson coefficient $c_1+c_2$ rather than $c_1-c_2$.

Double-winding Wilson loops and monopole confinement mechanisms

description: We consider "double-winding" Wilson loops in SU(2) gauge theory. These are contours which wind once around a loop $C_1$ and once around a loop $C_2$, where the two co-planar loops share one point in common, and where $C_1$ lies entirely in (or is displaced slightly from) the minimal area of $C_2$. We discuss the expectation value of such double-winding loops in abelian confinement pictures, where the spatial distribution of confining abelian fields is controlled by either a monopole Coulomb gas, a caloron ensemble, or a dual abelian Higgs model, and argue that in such models an exponential falloff in the sum of areas $A_1+A_2$ is expected. In contrast, in a center vortex model of confinement, the behavior is an exponential falloff in the difference of areas $A_2-A_1$. We compute such double-winding loops by lattice Monte Carlo simulation, and find that the area law falloff follows a difference-in-areas law. The conclusion is that even if confining gluonic field fluctuations are, in some gauge, mainly abelian in character, the spatial distribution of those abelian fields cannot be the distribution predicted by the simple monopole gas, caloron ensemble, or dual abelian Higgs actions, which have been used in the past to explain the area law falloff of Wilson loops.

description: Current observational facilities have yet to conclusively detect 103-104 M ⊙ intermediate-mass black holes (IMBHs) that fill in the evolutionary gap between seed black holes in the early universe and z ∼0 supermassive black holes. Dwarf galaxies present an opportunity to reveal active IMBHs amidst persistent star formation. We introduce photoionization simulations tailored to address key physical uncertainties: coincident versus noncoincident mixing of IMBH and starlight excitation, open versus closed geometries of surrounding gas clouds, and different shapes of the spectral energy distribution of active galactic nuclei (AGN). We examine possible AGN emission line diagnostics in the optical and mid-IR, and find that the diagnostics are often degenerate with respect to the investigated physical uncertainties. In spite of these setbacks, and in contrast to recent work, we are able to show that [O iii]/Hβ typically remains bright for dwarf AGN powered by IMBHs down to 103 M ⊙. Dwarf AGN are predicted to have inconsistent star-forming and Seyfert/LINER classifications using the most common optical diagnostics. In the mid-IR, [O iv] 25.9 μm and [Ar ii] 6.98 μm are less sensitive to physical uncertainties than are optical diagnostics. Based on these emission lines, we provide several diagrams of mid-IR emission line diagnostic diagrams with demarcations for separating starbursts and AGN with varying levels of activity. The diagrams are valid over a wide range of ionization parameters and metallicities out to z ∼0.1, so will prove useful for future JWST observations of local dwarf AGN in the search for IMBHs. We make our photoionization simulation suite freely available.
Scientific mapping of Iranian Inventor’s Patent Database(IPD) during1970-2014

Year: 2016

description: Patents, one of the important outputs of science and technology, have a tremendous role in wealth creation from knowledge and knowledge-Based economy. Patents are important indicators of determining the rate of a country progress in creativity development. This study, using scientometrics, identifies core inventors and highly cited (hot) inventions, and investigates the level of co-operation of Iranian inventors with other Iranian and non-Iranian co-operators in international patent databases, including United States Patent and Trademarks (USPT), World Intellectual Property Organization (WIPO), European Patent Office (EPO) and Japanese Patent Office (JPO), between 1970 and 2014. Microsoft Excel has been utilized to analyze the data. Also, Gephi software (8.2 edition) is used in order to depict the related scientific maps. The results of the research showed that the average of all Iranian invention registration in international databases has been 10.8 % per year. The most number and the most cited of inventions are in human necessities categories (agriculture, food stuffs, hygiene, and recreation). Besides, the least number and the least cited inventions are in paper and textiles category. All in all, 1054 Iranian inventors with foreign counterparts have had cooperated to register 475 patents, in which Iranian contribution rate has been 2.2%. The results also indicated that, the invention growth rate in international database had been rising in such a way that in 2014 the most number of inventions had been registered. Additionally, the inventions had been founded on the most prominent necessities of human being.
Research on alternative measures in the F1000 system with Google Scholar citation index
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2016

description: The purpose of this study was to assess the relationship between altmetrics measures of F1000 website and citation Indexes of Google scholar. Applied research and survey methods, citation analysis, and webometrics with descriptive analytical approach are used. The study population comprised 218 biomedical research papers have been indexed in F1000 system in the period 2012-2014. A sample of 100 research articles were purposely selected from F1000 system based on the purpose of the research. Variables associated with altmetrics measures were extracted from F1000 and variables associated with citation measures were from Google scholar. Data analysis was conducted by SPSS software version 16 using descriptive and inferential statistics. The results of this study indicate a significant positive correlation between variables associated with altmetrics and citation measures. They also confirm a strong positive correlation between Altmetrics indicators. However, the measures of the number of the authors and the funding supply of the articles show no significant correlation with altmetrics and citation measures. So an Altmetrics measure presents a new way to measure the impact of writers and publications which is a complementary to traditional assessment indicators. The significant correlation between altmetrics and citation metrics indicate that combination of traditional and altmetrics indicators presents a more complete history of the writer or the article  which provides clear dimensions of scientific assessment of research.
Coarsening dynamics at unstable crystal surfaces
Creators: name: Politi, Paolo
Publisher: name: arXiv
Year: 2015
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: In this paper we focus on crystal surfaces led out of equilibrium by a growth or erosion process. As a consequence of that the surface may undergo morphological instabilities and develop a distinct structure: ondulations, mounds or pyramids, bunches of steps, ripples. The typical size of the emergent pattern may be fixed or it may increase in time through a coarsening process which in turn may last forever or it may be interrupted at some relevant length scale. We study dynamics in three different cases, stressing the main physical ingredients and the main features of coarsening: a kinetic instability, an energetic instability, and an athermal instability.

description: Current study aims to investigate the status of user interfaces of non-Iranian digital libraries’ based on social bookmarking capabilities and characteristics to use by Iranian digital libraries. This research studies the characteristics and capabilities of top digital libraries’ user interfaces in the world based on social bookmarking used by library users. This capability facilitates producing, identifying, organizing, and sharing contents using tags. Survey method was used with descriptive-analytical approach in this study. Populations include non-Iranian digital libraries interfaces. Top ten digital libraries’ interfaces were selected as the sample. A researcher-made checklist prepared based on literature review and investigating four distinguished websites (Library Thing, Delicious, Amazon, and Google Book). Faced validity evaluated by 10 experts’ viewpoints, then reliability calculated 0.87.Findings of this study are important because of two reasons: first, it provides a comprehensive and an unambiguous vision for recognizing user interfaces’ basic capabilities and characteristics based on social bookmarking. Second, it can provide a base for designing digital libraries in Iran. The results showed that the majority of digital libraries around the world had not used web 2.0 characteristics such as producing, identifying, organizing, and sharing contents except two digital libraries (Google Books, and Ibiblio).

description: We give a explicit construction of $d$ locally indistinguishable orthogonal maximally entangled states in $\mathbb{C}^d\otimes\mathbb{C}^d$ for any $d\geq 4$. This gives an answer to the conjecture proposed by S. Bandyopadhyay in 2009. Thus it reflects the nonlocality of the fundamental feature of quantum mechanics.
