Carbohydrate-Active enZYmes: functional and applicative aspects of glycoside hydrolases
Creators: name: Ferrara, Maria Carmina
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2013

description: Carbohydrates play an important role in a variety of biological and industrial processes. The elucidation of the structure/function relationship of glycoside hydrolases (GHs) can help us to understand their implication in various biological phenomena and to exploit their catalytic features, i. e. in pharmacological therapies or to optimize industrial processes.
On the basis of these observations, this thesis work is directed to the study of GHs structure/function relationship and, besides the general introduction illustrated in chapter 1, it can be subdivided in two principal experimental sections (chapter 2 and 3). In chapter 2, the research plan was focused on the identification and biochemical characterization of novel glycosidases activities in the hyperthermophilic crenarchaeon Sulfolobus solfataricus. This study allowed to identify the first N-acetylglucosaminidase in this living domain, to increase our knowledge on the phylogeny of this class of enzymes, and to achieve additional data concerning their structural and functional features. Chapter 3 reports the structure/function study of the human lysosomal α-glucosidase, shading light on the factors responsible of its stabilization. The informations gained are exploited to identify novel pharmacological chaperones for the therapy of the lysosomal storage disorder known as Pompe disease.

description: We construct the Hubble diagram (HD) of Gamma-Ray Bursts (GRBs) with redshifts reaching up to $z \sim 6$, by using five luminosity vs. luminosity indicator relations calibrated with the Cardassian cosmology. This model has a major interesting feature: despite of being matter-dominated and flat, it can explain the present accelerate expansion of the universe. This is the first study of this class of models using high redshift GRBs. We have performed a $χ$-square statistical analysis of the GRBs calibrated with the Cardassian model, and also combined them with both the current Cosmic Microwave Background and Baryonic Acoustic Oscillation data. Our results show consistency between the current observational data and the model predictions. In particular, the best-fit parameters obtained from the $χ^2$-analysis are in agreement with those obtained from the Concordance Cosmology ($Λ$-CDM). We determine the redshift at which the universe would start to follow the Cardassian expansion, i. e., \zc, and both the redshift at which the universe had started to accelerate, i. e., \zac, and the age-redshift relation $H_0t_0$. Our results also show that the universe, from the point of view of GRBs, had undergo a transition to acceleration at a redshift $z \approx 0.2-0.7$, which agrees with the SNIa results. Hence, after confronting the Cardassian scenario with the GRBs HD and proving its consistency with it, we conclude that GRBs should indeed be considered a complementary tool to several other astronomical observations for studies of high accuracy in cosmology.

Human DNA replication factors:
new interactions and functional significance
Creators: name: De Falco, Mariarosaria
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2013

description: The Mini-chromosome maintenance (Mcm) complex is a central component of the DNA unwinding reaction during eukaryotic DNA replication. DNA primase activity is required at the DNA replication fork to synthesize short RNA primers for DNA chain elongation on the lagging strand. Using purified Mcm and DNA polymerase α-primase complexes, we find that both Mcm4/6/7 and  Mcm2~7 complex  interact with  the DNA polymerase α-primase oloenzyme and also with  the hetero-dimeric DNA primase composed of the p48 and p58 subunits. Both the Mcm4/6/7 and Mcm2~7 complexes stimulate RNA primer synthesis by DNA primase in vitro. Our findingsindicate that a direct physical interaction between primase and Mcm may facilitate priming reaction.
The eukaryotic DNA replication protein Mcm10 associates with chromatin in early S-phase and is required for assembly and function of the replication fork protein machinery. Another essential component of the eukaryotic replication fork is Cdc45, which is required for both initiation and elongation of DNA replication. Here we report for the first time physical and functional interactions of human Mcm10 and Cdc45. We first demonstrated that Mcm10 and Cdc45 interact in vivo and in vitro. We have detected a direct physical interaction between CTD (C-Terminal Domain of Mcm10) while Mcm10 ID (Internal Domain) with Cdc45 takes place only in the presence of DNA. Both ID and CTD show DNA binding capability. Our results demonstrate that human Mcm10 and Cdc45 directly interact and establish a mutual cooperation in DNA binding.

description: We extend the SDSS Stripe 82 Standard Stars Catalog with post-2007 SDSS imaging data. This improved version lists averaged SDSS ugriz photometry for nearly a million stars brighter than r~22 mag. With 2-3x more measurements per star, random errors are 1.4-1.7x smaller than in the original catalog, and about 3x smaller than for individual SDSS runs. Random errors in the new catalog are ~< 0.01 mag for stars brighter than 20.0, 21.0, 21.0, 20.5, and 19.0 mag in u, g, r, i, and z-bands, respectively. We achieve this error threshold by using the Gaia Early Data Release 3 (EDR3) Gmag photometry to derive gray photometric zeropoint corrections, as functions of R.A. and Declination, for the SDSS catalog, and use the Gaia BP-RP colour to derive corrections in the ugiz bands, relative to the r-band. The quality of the recalibrated photometry, tested against Pan-STARRS1, DES, CFIS and GALEX surveys, indicates spatial variations of photometric zeropoints <=0.01 mag (RMS), with typical values of 3-7 millimag in the R.A., and 1-2 millimag in the Declination directions, except for

description: (Abridged) We present deep, sub-horizontal branch, multi-colour photometry of the Andromeda II dwarf spheroidal (And II dSph) taken with Subaru Suprime-Cam. We identify a red clump population in this galaxy, the first time this feature has been detected in a M31 dSph, which are normally characterized as having no significant intermediate age populations. We construct radial profiles for the various stellar populations and show that the horizontal branch has a nearly constant density spatial distribution out to large radius, whereas the reddest red giant branch stars are centrally concentrated in an exponential profile. We argue that these populations trace two distinct structural components in And II and show that this assumption provides a good match to the overall radial profile of this galaxy. The extended component dominates the stellar populations at large radius, whereas the exponential component dominates the inner few arcminutes. We show that the two components have very different stellar populations; the exponential component has an average age of $\sim 7 - 10$ Gyrs old, is relatively metal-rich ([Fe/H] $\sim -1$) but with a significant tail to low metallicities, and possesses a red clump. The extended component, on the other hand, is ancient ($\sim 13$ Gyrs), metal-poor ([Fe/H] $\sim -1.5$) with a narrower dispersion $σ_{\rm [Fe/H]} \simeq 0.28$, and has a well developed blue horizontal branch. The extended component contains approximately three-quarters of the light of And II and its unusual density profile is unique in Local Group dwarf galaxies. This suggests that its formation and/or evolution may have been quite different to other dwarf galaxies.

The standard "static" spherically symmetric ansatz with perfect fluid source revisited

description: Considering the standard "static" spherically symmetric ansatz ds2 = -B(r) dt2 + A(r) dr2 + r2 dOmega2 for Einstein's Equations with perfect fluid source, we ask how we can interpret solutions where A(r) and B(r) are not positive, as they must be for the static matter source interpretation to be valid. Noting that the requirement of Lorentzian signature implies A(r) B(r) >0, we find two possible interpretations: (i) The nonzero component of the source four-velocity does not have to be u0. This provides a connection from the above ansatz to the Kantowski-Sachs (KS) spacetimes. (ii) Regions with negative A(r) and B(r) of "static" solutions in the literature must be interpreted as corresponding to tachyonic source. The combinations of source type and four-velocity direction result in four possible cases. One is the standard case, one is identical to the KS case, and two are tachyonic. The dynamic tachyonic case was anticipated in the literature, but the static tachyonic case seems to be new. We derive Oppenheimer-Volkoff-like equations for each case, and find some simple solutions. We conclude that new "simple" black hole solutions of the above form, supported by a perfect fluid, do not exist.

Characterization of the Critical Submanifolds in Quantum Ensemble Control Landscapes

description: A quantum control landscape is defined as the physical objective as a function of the control variables to be optimized. Analyzing the topology of these landscapes is important for understanding the origins of the increasing number of laboratory successes in the optimal control of quantum processes. This paper proposes a simple scheme to compute the characteristics of the critical topology of the quantum ensemble control landscapes for observables, showing that the set of disjoint critical submanifolds one-to-one corresponds to a finite number of contingency tables that solely depend on the degeneracy structure of the eigenvalues of the initial system density matrix and the observable to be controlled. The landscape characteristics can be calculated as functions of the table entries, including the dimensions and the numbers of positive and negative eigenvalues of the Hessian quadratic form of each of the connected components of the critical submanifolds. Typical examples are given to illustrate the effectiveness of this method.

Orthopteran diversity and distribution in the Monviso Natural Park (Western Italian Alps) (Insecta: Orthoptera)
Creators: name: Giuliano, Davide
Publisher: name: Fragmenta entomologica
Year: 2022

description: The Alps represent a biodiversity hotspot in Europe, especially due to the occurrence of many endemic plant and animal species. In particular, the southwestern portions of the Alpine range have been identified as a centre of endemism for many taxa, including Orthoptera, thanks to the peculiar biogeographical history of this area. In this research, the orthopteran fauna living in one of the main massifs of the Italian western Alps (Monviso massif, Cottian Alps) was investigated, focusing on the Monviso Natural Park and the SAC/SPA IT1160058 “Gruppo del Monviso e Bosco dell’Alevé” territories. Merging field data with information gathered from bibliographical sources, public and private databases, a checklist of 51 species was compiled for the study area, including 7 W-Alpine endemic species and 4 Near-threatened taxa according to the European IUCN orthopteran Red List. Species distribution has been mapped in detail within the park, identifying core areas for endemic and near-threatened species, as well as for the overall orthopteran diversity, where desirable research and conservation efforts should be focused in future. In addition, combining field data with the information obtained by means of a little systematic review, the known elevation extremes of 43 orthopteran species observed in the study area are updated for the W-Alpine region, significantly improving the current knowledge on their altitudinal distribution in this area, especially in view of the upward range shifts expected in the ongoing climate change scenario.

Recognition of emotional facial expression by abusive mothers and their children
Creators: name: During, Sara May
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this investigation was to examine the ability of abused children and their abusive mothers to decode facial expressions of emotion relative to non-abused children and their mothers and to assess the intradyadic relationship of these abilities. Forty-six children and their mothers (23 normal and 23 abusive dyads) were individually presented with a series of photographs of six posed emotional expressions, and asked to make a first-, second- and third-choice for each target emotion. Results indicated that abused children were less accurate than non-abused children in the identification of emotional expression, that younger children were less accurate that older children, and that children were less accurate with pictures of adults versus pictures of children. In comparison to the non-abused children, the abused children also appeared to be less orderly and systematic in their structuring of emotions. Conversely, the results indicated that abusive and non-abusive mothers did not significantly differ in the identification of emotional expression, nor in the structuring of the emotion domain. Additionally, abusive mothers did not show significantly greater unrealistic expectations of their children's behavior than did non-abusive mothers, but did perceive their children as having more behavior problems than did non-abusive mothers. The results were discussed in terms of issues related to maternal and child behavior and cognitions, patterning of emotional recognition responses, and the specific methodology employed in this study.

description: Deficit of information zero-way was proposed in HorodeckiHHOSSS2005 as one of possible measures of quantumness of correlations. Numerical calculations suggested that there exist such states for which this quantity is almost equal to mutual information. In this paper we present a family of states for which we have equality between above measure of quantumness of correlations and the measure of total correlations -- mutual information. It means that whole correlations in these states have, in some sense, quantum character and that quantum correlations do not necessarily imply classical correlations. We prove this intriguing feature for a subclass of 2x2 separable states. We also present numerical result suggesting that this interesting situation might also happen for 2x2 entangled states.

description: We study the effects of spatial constraints on the structural properties of networks embedded in one or two dimensional space. When nodes are embedded in space, they have a well defined Euclidean distance $r$ between any pair. We assume that nodes at distance $r$ have a link with probability $p(r) \sim r^{- δ}$. We study the mean topological distance $l$ and the clustering coefficient $C$ of these networks and find that they both exhibit phase transitions for some critical value of the control parameter $δ$ depending on the dimensionality $d$ of the embedding space. We have identified three regimes. When $δ2d$ the networks are ``large'' worlds $l \sim N^{1/d}$ with high clustering. Our results indicate that spatial constrains have a significant impact on the network properties, a fact that should be taken into account when modeling complex networks.

“She parted the curtains; she looked”: finestre spalancate su realtà apparentemente inconciliabili in Mrs Dalloway di Virginia Woolf
Creators: name: Negrello, Giulia
Publisher: name: Università degli  Studi di Milano
Year: 2015
Subjects: Finestra, follia, doppio, suicidio, percezione

description: Mrs Dalloway is probably the most multifaceted and complex novel by Virginia Woolf; this complexity derives from the writer’s desire to represent life seen both from the points of view of the insane and the sane: “the world seen by the sane and the insane side by side” (D2, 14 ottobre 1922, p. 207). The novel, thus, is structured on two main plots, whose protagonists are Mrs Dalloway on one side (representing the ‘sane truth’) and the veteran Septimus Warren-Smith on the other (representing the ‘insane truth’). During one single day, the stories of the protagonists develop without intersecting in the city of London. In such a complex design, the window becomes a strong symbol of communication and connection between these two worlds which only seem to be detached and independent. Not only that, but since the beginning of the novel the window symbolises also the passage from a time frame to another, from the present moment to a more or less distant past, thus permitting the author to linger on the past of the characters, revealing aspects of their personalities that, otherwise, would remain unknown. This essay then will present the symbology of the window in Virginia Woolf’s novel through the analysis of the most effective episodes of Mrs Dalloway, where this object becomes a mean of communication between apparently disconnected realities like sanity and madness, youth and adulthood, past and present and life and death.

Year: 2015

description: The window can include a lot of different symbolic values and can be considered at the same time a border and a protection area: this architectural element allows the pessoan heteronomy Álvaro de Campos to observe other people’s life, taking place in the road. His gaze, attentive and absorbed at the same time, leads to the birth of the poem Tabacaria (1928). It is a poem that from the beginning portrays the collapse of illusion: the poet is a man who chooses not to live his own life, preferring to take refuge behind a window, a profound disillusionment narrated through the dialectics of ‘outside and inside’. In Tabacaria the window allows two opposing worlds – otherwise incompatible – to come together, although they remain separate, a contrast defined by the Pessoa-Campos as alienating, reminiscent of the perceptual dialectic theorized by the philosopher Merleau-Ponty. A window, an architectural barrier that allows you to see and be seen at the same time, putting together two seemingly irreconcilable worlds. ‘Tecnema’, which has always fascinated and here becomes the place of observation of the ‘tabacaria’, is the symbol of an illusory world. From a real and ordinary situation, ‘finished’ and enclosed by the walls of the attic, the poet conveys a feeling of infinity, eternity, through an expansion of the senses disintegrated from the tediousness of the existential poetic subject.

description: We study the quasinormal modes and non-linear dynamics of a simplified model of semi-holography, which consistently integrates mutually interacting perturbative and strongly coupled holographic degrees of freedom such that the full system has a total conserved energy. We show that the thermalization of the full system can be parametrically slow when the mutual coupling is weak. For typical homogeneous initial states, we find that initially energy is transferred from the black brane to the perturbative sector, later giving way to complete transfer of energy to the black brane at a slow and constant rate, while the entropy grows monotonically for all time. Larger mutual coupling between the two sectors leads to larger extraction of energy from the black brane by the boundary perturbative system, but also quicker irreversible transfer of energy back to the black brane. The quasinormal modes replicate features of a dissipative system with a softly broken symmetry including the so-called k-gap. Furthermore, when the mutual coupling is below a critical value, there exists a hybrid zero mode with finite momentum which becomes unstable at higher values of momentum, indicating a Gregory-Laflamme type instability. This could imply turbulent equipartitioning of energy between the boundary and the holographic degrees of freedom in the presence of inhomogeneities.

DISENCHANTMENT WITH LIBERALISM IN POST-SOVIET SOCIETIES

description: In post-Soviet societies, liberalism has come to be perceived as contradictory to the rule of law and norms of decency, even as the antithesis of order and associated with chaos. However, it may be accurate to talk about disenchantment with misperceived liberalism and a defensive reflex by societies that are struggling with their post-totalitarian burdens in the face of misrepresented liberal ideas. It is important to analyze the reasons for, implications of, and ways to overcome this awkward phenomenon, since the major problems of the region cannot be solved without recourse to liberal ideas.

The paper argues that the methods used to bring liberalism to a number of post-Soviet societies, particularly Russia, proved to be wrong. Nonetheless, we have to be optimistic about the prospects for developing liberal ideas in the region. For one thing, contrary to what is usually stated, the seeming disenchantment with liberalism does not follow from the civilizational underpinnings of contemporary post-Soviet societies. The basic ideas of liberal philosophy are not something unwanted by or alien to the great majority of post-Soviet people. Their disenchantment with liberalism is not a matter of general principles, but rather a collateral result of abuses of liberalism and systematic disinformation.

It seems proper to assert that, after the collapse of the totalitarian system, post-Soviet societies have returned to their natural path of developing liberal values, which had been seriously interrupted by the Soviet system. A liberal outlook is indispensable to finding durable solutions to most problems and difficulties that have befallen post-Soviet societies. In the examples of Russia and Kazakhstan, it can be argued that a post-Soviet society will inevitably transition to a society with a more liberal outlook, if the internal demands for achieving this goal can be maintained. However, robust internal demands for liberalization can emerge only through promoting a kind of liberalism that is acceptable to the minds and hearts of the people and elites of post-Soviet countries, which takes into account the peculiarities of their economic and social structures.

description: We present an analysis of the dispersed spectral data from 11 epochs (March 2011 to September 2018) of supernova remnant (SNR) 1987A observations performed with Chandra. These observations were performed with the High Energy Transmission Grating (HETG) as part of our ongoing Chandra monitoring campaign of SNR 1987A, whose 1st-order dispersed spectrum provides a significantly greater energy resolution than the previously-published 0th-order spectrum. Our data sets with moderate exposure times of ~50-70ks per epoch cover the time period between deep Chandra HETG observations (with individual exposures >200ks) taken in March 2011 and March 2018. These data have a much higher cadence than the widely-spaced deep high-resolution spectra, at the expense of total exposure time. While statistical uncertainties are large due to low photon count statistics in the observed 1st-order spectra, we find that spectral model parameters are generally in line with the shock wave propagating into the medium beyond the dense inner ring, as suggested by Frank et al. 2016. As the reverse shock begins ionizing the heavier elements of the supernova ejecta interior to the equatorial ring, spectral fit parameters are expected to change as the chemical makeup and physical properties of the shocked gas evolve. Based on our broadband spectral model fits, we find that abundance values appear to be constant in this time period. While our results are somewhat limited due to photon statistics, we demonstrate the utility of the dispersed HETG spectral analysis that can be performed with our regular Chandra monitoring observations of SNR 1987A.

description: Volumetric distributed Denial-of-Service (DDoS) attacks have become one of the most significant threats to modern telecommunication networks. However, most existing defense systems require that detection software operates from a centralized monitoring collector, leading to increased traffic load and delayed response. The recent advent of Data Plane Programmability (DPP) enables an alternative solution: threshold-based volumetric DDoS detection can be performed directly in programmable switches to skim only potentially hazardous traffic, to be analyzed in depth at the controller. In this paper, we first introduce the BACON data structure based on sketches, to estimate per-destination flow cardinality, and theoretically analyze it. Then we employ it in a simple in-network DDoS victim identification strategy, INDDoS, to detect the destination IPs for which the number of incoming connections exceeds a pre-defined threshold. We describe its hardware implementation on a Tofino-based programmable switch using the domain-specific P4 language, proving that some limitations imposed by real hardware to safeguard processing speed can be overcome to implement relatively complex packet manipulations. Finally, we present some experimental performance measurements, showing that our programmable switch is able to keep processing packets at line-rate while performing volumetric DDoS detection, and also achieves a high F1 score on DDoS victim identification.

description: Pre-main sequence (PMS) stars are known to produce powerful X-ray flares which resemble magnetic reconnection solar flares scaled by factors up to 10^4. However, numerous puzzles are present including the structure of X-ray emitting coronae and magnetospheres, effects of protoplanetary disks, and effects of stellar rotation. To investigate these issues in detail, we examine 216 of the brightest flares from 161 PMS stars observed in the Chandra Orion Ultradeep Project (COUP). These constitute the largest homogeneous dataset of PMS, or indeed stellar flares at any stellar age, ever acquired. Our effort is based on a new flare spectral analysis technique that avoids nonlinear parametric modeling. It can be applied to much weaker flares and is more sensitive than standard methods. We provide a catalog with >30 derived flare properties and an electronic atlas for this unique collection of stellar X-ray flares. The current study (Paper I) examines the flare morphologies, and provides general comparison of COUP flare characteristics with those of other active X-ray stars and the Sun. Paper II will concentrate on relationships between flare behavior, protoplanetary disks, and other stellar properties. Several results are obtained. First, the COUP flares studied here are among the most powerful, longest, and hottest stellar X-ray flares ever studied. Second, no significant statistical differences in peak flare luminosity or temperature distributions are found among different morphological flare classes, suggesting a common underlying mechanism for all flares. Third, comparison with the general solar-scaling laws indicates that COUP flares may not fit adequately proposed power-temperature and duration-temperature solar-stellar fits. Fourth, COUP super-hot flares are found to be brighter but shorter than ... ABRIDGED

Year: 1948

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: We perform a hierarchical Bayesian inference to investigate the population properties of the coalescing compact binaries involving at least one neutron star (NS). With the current observation data, we can not rule out either of the Double Gaussian, Single Gaussian and Uniform NS mass distribution models, although the mass distribution of the Galactic NSs is slightly preferred by the gravitational wave (GW) observations. The mass distribution of black holes (BHs) in the neutron star-black hole (NSBH) population is found to be similar to that for the Galactic X-ray binaries. Additionally, the ratio of the merger rate densities between NSBHs and BNSs is estimated to be about 3 : 7. The spin properties of the binaries, though constrained relatively poor, play nontrivial role in reconstructing the mass distribution of NSs and BHs. We find that a perfectly aligned spin distribution can be ruled out, while a purely isotropic distribution of spin orientation is still allowed.
Sex-role orientation and sex stereotyping influences on same- and cross-sex friendships

description: This study was designed to investigate the influence of two individual difference variables--sex-role orientation and level of sex stereotyping—on the quality of people's own same- and opposite-sex friendships, and their attitudes toward same- and opposite-sex friendships in general. It was predicted that androgynous individuals would experience the highest quality in their friendships, followed by the sex-typed and undifferentiated. Level of stereotyping was predicted to influence both the quality of peoples' friendships, and their evaluations of the concepts same- and opposite-sex friendships. High-sex stereotyped persons were expected to have lower quality friendships and have less favorable attitudes toward cross-sex friendships compared with the low stereotyped. One hundred and one adults (62 females, 39 males) sampled from the City of Vancouver completed a series of questions designed to tap the quality of their same-and cross-sex friendships, and their attitudes toward sairie-and cross-sex friendships. The Bern Sex-Role Inventory (BSRI, Bern, 1974) was used to measure sex typing (androgynous, sex-typed, undifferentiated) and an instrument developed by the author was used to test level of sex stereotyping. As predicted, androgyny was related to better quality friendships. Androgynous individuals had significantly higher quality scores than either sex-typed or undifferentiated persons. Quality scores were not significantly different for sex-typed individuals compared with undifferentiated. These findings were interpreted in terms of the greater behavioral flexibility associated with androgyny. Although not predicted, sex typing was also a significant factor in evaluations of friendships and attitudes toward cross-sex friendships specifically. Androgynous individuals gave significantly higher evaluations to friendships and were more accepting of cross-sex friendships than persons in the other two sex-role orientation groups. In light of this finding a modification was made to the original theoretical framework to account for sex typing effects on evaluations of friendships. None of the predictions for level of sex stereotyping influences on quality and evaluation of friendships was supported. Psychometric problems with the measures used in the present study may have contributed to these non-significant findings. Other findings showed same-sex friendships received significantly higher quality ratings than cross-sex and same-sex friendships received more positive evaluations compared with opposite-sex friendships, although these latter findings were non-significant.

description: The interlace polynomial q was introduced by Arratia, Bollobas, and Sorkin. It encodes many properties of the orbit of a graph under edge local complementation (ELC). The interlace polynomial Q, introduced by Aigner and van der Holst, similarly contains information about the orbit of a graph under local complementation (LC). We have previously classified LC and ELC orbits, and now give an enumeration of the corresponding interlace polynomials of all graphs of order up to 12. An enumeration of all circle graphs of order up to 12 is also given. We show that there exist graphs of all orders greater than 9 with interlace polynomials q whose coefficient sequences are non-unimodal, thereby disproving a conjecture by Arratia et al. We have verified that for graphs of order up to 12, all polynomials Q have unimodal coefficients. It has been shown that LC and ELC orbits of graphs correspond to equivalence classes of certain error-correcting codes and quantum states. We show that the properties of these codes and quantum states are related to properties of the associated interlace polynomials.

Royal power and the war with Granada
Creators: name: Conroy, James George
Publisher: name: University of British Columbia
Year: 2010

description: One of the most important issues faced by the society of the Iberian Peninsula during the fifteenth century was the conflict between the demands of the monarchy and the accumulated rights of the nobility. The Reconquista facilitated the growth of a privileged warrior class, which resulted in a nobility entrenched in their wealth and historic privileges of rule. The Crown frequently challenged this domination, yet with little success, until the reigns of Isabel of Castile and Fernando of Aragon. These monarchs successfully channeled the power of the nobility into forms that increased the power of the monarchy without alienating the wealth and prestige of the nobles. The purpose of this thesis is to show how the process of controlling the nobility was aided largely by the growth in military power of the monarchy, developed and expanded through the war with Granada, from 1480 to 1492. This war demanded a vast increase in the size and a change in the composition of the Castilian army, with a corresponding increase in the financial, social and technological infrastructure needed to support it. The campaigns against Granada were focused primarily around numerous sieges, with gunpowder siege artillery as the primary weapon. The dissertation shows how this artillery was vital to the eventual success of Castile over Granada. In support of the artillery, large infantry armies were raised by the Monarchs to conduct the actual sieges and protect Castilian supply lines. The cavalry, formerly the dominant arm of the Castilian army, was relegated to skirmishing. The introduction of effective firepower placed at the disposal of the monarchs sufficient military force to control the nobility and extend their influence throughout Castile, Aragon, Granada, and Navarre, and to unify politically much of the Peninsula. This reorientation of the emphasis in the Castilian military system had enormous political, social, financial and military ramifications for Castile. The State intruded into much of Castilian society, in the form of bureaucrats and tax collectors. The financial affairs of the monarchs expanded to fit the demands of the war effort, eventually absorbing a large proportion of the revenues of the Church and that of the nobility as well. This growth of state power eventually overrode much of the legal isolation of the different areas of the Peninsula. The massive effort required of the peoples of Spain also promoted a social unification, in that the concept of a vital task successfully concluded was shared by all. The success of the war also fostered a crusade mentality among Spaniards and the strengthening of the influence of the Catholic religion under the direction of the monarchs. In these ways, the military demands of a decade of war against Granada facilitated and forced the growth of a centralized, bureaucratic state on a society dominated by aristocratic pretensions and regional factionalism.

description: The EU is surrounded by areas of limited statehood (ALS) and contested orders (CO) in its southern and eastern neighbourhood. Resilience has become a focus of attention in the academic debate on how to successfully deal with ALS and CO. Moreover, resilience-building is a new cornerstone in the EU’s foreign and security policy. However, to what extent is resilience a mechanism to cope with ALS and CO? What are the sources of resilience? To what extent does the EU act as a resilience builder or spoiler in its neighbourhood? By presenting a new conceptual framework for analysing the interplay between risks, resilience, and governance breakdown/violent conflict as well as through in-depth empirical evidence, this special issue puts forward three key arguments. First, resilience is a key mechanism to prevent governance breakdown and violent conflict in the EU’s neighbourhood. Second, three sources are key in building resilience: Social trust within societies and communities, legitimacy of (state and non-state) governance actors and institutions, as well as effective, fair, and inclusive governance institutions. Third, if external actors, such as the EU, seek to build resilience, they need to factor in long-time horizons, in-depth local knowledge, and a clearly designed strategy.
