description: This work presents a review of high-order hybridisable discontinuous Galerkin (HDG) methods in the context of compressible flows. Moreover, an original unified framework for the derivation of Riemann solvers in hybridised formulations is proposed. This framework includes, for the first time in an HDG context, the HLL and HLLEM Riemann solvers as well as the traditional Lax-Friedrichs and Roe solvers. HLL-type Riemann solvers demonstrate their superiority with respect to Roe in supersonic cases due to their positivity preserving properties. In addition, HLLEM specifically outstands in the approximation of boundary layers because of its shear preservation, which confers it an increased accuracy with respect to HLL and Lax-Friedrichs. A comprehensive set of relevant numerical benchmarks of viscous and inviscid compressible flows is presented. The test cases are used to evaluate the competitiveness of the resulting high-order HDG scheme with the aforementioned Riemann solvers and equipped with a shock treatment technique based on artificial viscosity.

description: We study stable spheroidal configurations of magnetized Strange Stars using an axially symmetric metric in spherical coordinates that uses a gamma parameter to link the anisotropy in the Equation of State due to the magnetic field with the deformation of the star. The stars are composed by magnetized Strange Quark Matter described within the framework of the MIT-Bag model. Their masses, radii, eccentricity, redshift and mass quadrupole moment are computed. Results are compared with spherical Strange Stars solutions obtained with TOV equations and observational data of Strange Stars candidates. In the spheroidal model the observables depend directly on the deformation of the stars, and even though it is small, the observables strongly deviate from the corresponding spherical configurations. Thus, the highest values of the mass quadrupole moment correspond to the intermediate mass regime. These differences might allow to discriminate between models with/without magnetic field when compared with observations.

description: A popular data-driven method for choosing the bandwidth in standard kernel regression is cross-validation. Even when there are outliers in the data, robust kernel regression can be used to estimate the unknown regression curve [Robust and Nonlinear Time Series Analysis. Lecture Notes in Statist. (1984) 26 163--184]. However, under these circumstances standard cross-validation is no longer a satisfactory bandwidth selector because it is unduly influenced by extreme prediction errors caused by the existence of these outliers. A more robust method proposed here is a cross-validation method that discounts the extreme prediction errors. In large samples the robust method chooses consistent bandwidths, and the consistency of the method is practically independent of the form in which extreme prediction errors are discounted. Additionally, evaluation of the method's finite sample behavior in a simulation demonstrates that the proposed method performs favorably. This method can also be applied to other problems, for example, model selection, that require cross-validation.

description: Degenerative disc disease is associated with increased expression of pro-inflammatory cytokines in the intervertebral disc (IVD). However, it is not completely clear how inflammation arises in the IVD and which cellular compartments are involved in this process. Recently, the endoplasmic reticulum (ER) has emerged as a possible modulator of inflammation in age-related disorders. In addition, ER stress has been associated with the microenvironment of degenerated IVDs. Therefore, the aim of this study was to analyze the effects of ER stress on inflammatory responses in degenerated human IVDs and associated molecular mechanisms. Gene expression of ER stress marker GRP78 and pro-inflammatory cytokines IL-6, IL-8, IL-1 beta, and TNF-alpha was analyzed in human surgical IVD samples (n = 51, Pfirrmann grade 2-5). The expression of GRP78 positively correlated with the degeneration grade in lumbar IVDs and IL-6, but not with IL-1 beta and TNF-alpha. Another set of human surgical IVD samples (n = 25) was used to prepare primary cell cultures. ER stress inducer thapsigargin (Tg, 100 and 500 nM) activated gene and protein expression of IL-6 and induced phosphorylation of p38 MAPK. Both inhibition of p38 MAPK by SB203580 (10 mu M) and knockdown of ER stress effector CCAAT-enhancer-binding protein homologous protein (CHOP) reduced gene and protein expression of IL-6 in Tg-treated cells. Furthermore, the effects of an inflammatory microenvironment on ER stress were tested. TNF-alpha (5 and 10 ng/mL) did not activate ER stress, while IL-1 beta (5 and 10 ng/mL) activated gene and protein expression of GRP78, but did not influence [Ca2+](i) flux and expression of CHOP, indicating that pro-inflammatory cytokines alone may not induce ER stress in vivo. This study showed that IL-6 release in the IVD can be initiated following ER stress and that ER stress mediates IL-6 release through p38 MAPK and CHOP. Therapeutic targeting of ER stress response may reduce the consequences of the harsh microenvironment in degenerated IVD.

description: Obiettivo: Stabilire se l'esercizio fisico possa esercitare effetti anti-infiammatori attraverso la riduzione dei livelli di HMGB1 nelle donne con cancro al seno (CM).

Metodi: Abbiamo analizzato i dati monocentrici del progetto DIANA-V (DIETA E ANDROGENI). La popolazione di studio consisteva di 94 pazienti randomizzati in due gruppi: 61 pazienti (53 ± 8 anni, gruppo training) sono stati assegnati a un intervento di esercizio fisico strutturato (3 volte / settimana per i primi 3 mesi, e una volta a settimana in nove mesi ); mentre 33 pazienti (52 ± 7 anni, gruppo di controllo) hanno seguito solo le indicazioni generali di aderire alle proposte di intervento di stile di vita del protocollo DIANA. All'inizio dello studio e dopo 12 mesi, tutti i pazienti sono stati sottoposti a: test da sforzo cardiopolmonare,  valutazione biochimica [HMGB1, proteina C-reattiva ad alta sensibilità (hs-CRP), interleuchina-6 (IL-6)], profilo lipidico e glicemico.

Risultati: Non ci sono state differenze significative tra i gruppi nel profilo clinico e infiammatorio al tempo zero. All'interno del gruppo training, solo 19 pazienti hanno avuto una alta aderenza al programma di esercizio. Dopo la  stratificazione della popolazione di studio in base al livello di aderenza all'esercizio, i livelli di HMGB1 ad 1 anno risultavano più bassi tra i pazienti più aderenti al training(p per trend = 0.001). Dopo ulteriore aggiustamento per età, indice di massa corporea e valori di base, i livelli di HMGB1 ad 1 anno risultavano significativamente e inversamente associati al livello di aderenza all'esercizio (B = -0.97, SE = 0,43, p = 0,01).

Conclusioni: Il training fisico ad intensità moderata in sopravvissuti del CM è associata a livelli di HMGB1 ridotti, i quali sono proporzionali al livello di aderenza al programma di training, indipendentemente da altri classici marcatori di infiammazione, suggerendo un effetto anti-infiammatorio indotto dall' esercizio fisico mediato dall' HMGB1.

description: The transfer of Microcystis aeruginosa from freshwater to estuaries has been described worldwide and salinity is reported as the main factor controlling the expansion of M. aeruginosa to coastal environments. Analyzing the expression levels of targeted genes and employing both targeted and non-targeted metabolomic approaches, this study investigated the effect of a sudden salt increase on the physiological and metabolic responses of two toxic M. aeruginosa strains separately isolated from fresh and brackish waters, respectively, PCC 7820 and 7806. Supported by differences in gene expressions and metabolic profiles, salt tolerance was found to be strain specific. An increase in salinity decreased the growth of M. aeruginosa with a lesser impact on the brackish strain. The production of intracellular microcystin variants in response to salt stress correlated well to the growth rate for both strains. Furthermore, the release of microcystins into the surrounding medium only occurred at the highest salinity treatment when cell lysis occurred. This study suggests that the physiological responses of M. aeruginosa involve the accumulation of common metabolites but that the intraspecific salt tolerance is based on the accumulation of specific metabolites. While one of these was determined to be sucrose, many others remain to be identified. Taken together, these results provide evidence that M. aeruginosa is relatively salt tolerant in the mesohaline zone and microcystin (MC) release only occurs when the capacity of the cells to deal with salt increase is exceeded.

L'obiettivo principale è fornire un'idea di come differenti regimi termici influiscano sul comportamento di questi animali.
Per la spigola si è proceduto ad una acclimatazione a tre differenti regimi termici per un periodo di 21 giorni, seguito da una serie di quattro test comportamentali (test di foraggiamento, test olfattivo, mirror test e test avversivo) che hanno mostrato un'influenza del regime termico su alcuni comportamenti.
Per il pesce zebra si è proceduto ad una acclimatazione a tre differenti regimi termici di due linee wild-type differenti, quella commerciale e quella AB.
Il trattamento termico nella linea commerciale è durato: i) per il primo gruppo quattro giorni, seguito da una serie di tre test comportamentali (novel diving tank test, dark/light preference test e group preference test); ii) per il secondo gruppo 21 giorni, seguito da una serie di quattro test comportamentali (novel diving tank test, dark/light preference test, group preference test e mirror test).
Il trattamento termico nella linea AB è durato 21 giorni, seguito da una serie di quattro test comportamentali (novel diving tank test, dark/light preference test, group preference test e mirror test).
In tutti i trattamenti termici si è potuto osservare un'influenza del regime termico sul comportamento del pesce zebra.
Quindi si è cercato di fornire un'idea di come valori non ottimali di temperatura possano influire sul comportamento di queste specie di pesci.

description: São Paulo is the largest city in South America, with high criminality rates. The number and type of crimes varies considerably around the city, assuming different patterns depending on urban and social characteristics. In this scenario, enabling tools to explore particular locations of the city is very important for domain experts to understand how urban features as to mobility, passersby behavior, and urban infrastructures can influence the quantity and type of crimes. In present work, we present CrimAnalyzer, a visualization assisted analytic tool that allows users to analyze crime behavior in specific regions of a city, providing new methodologies to identify local crime hotspots and their corresponding patterns over time. CrimAnalyzer has been developed from the demand of experts in criminology and it deals with three major challenges: i) flexibility to explore local regions and understand their crime patterns, ii) Identification of not only prevalent hotspots in terms of number of crimes but also hotspots where crimes are frequent but not in large amount, and iii) understand the dynamic of crime patterns over time. The effectiveness and usefulness of the proposed system are demonstrated by qualitative/quantitative comparisons as well as case studies involving real data and run by domain experts.

description: We implement a Chern-Simons (CS) contribution into the compact QED3 description of the antiferromagnetic Heisenberg model in two dimensions at zero temperature. The CS term allows for the conservation of the SU(2) symmetry of the quantum spin system and fixes the flux through a plaquette to be a multiple of pi as was shown by Marston. We work out the string tension of the confining potential which acts between the spinons and show that the CS term induces a screening effect on the magnetic field only. The confining potential between spinons is not affected by the CS flux. The strict site-occupation by a single spin 1/2 is enforced by the introduction of an imaginary chemical potential constraint.

Comparison of Canadian and Korean preadolescent’s attribution patterns affecting inductive rule learning
Creators: name: Lee, Hyun Sook
Publisher: name: University of British Columbia
Year: 2009

description: The primary purpose of this study was to test the attribution theory of motivation cross-culturally by comparing performance and attribution patterns on inductive rule learning in two different cultures (Canadian & Korean) within the framework of collectivism vs. individualism. Two hypotheses were formed: 1) Korean and Canadian students would show differences in attribution patterns following success or failure outcome due to different cultural emphasis. 2) Given the effort attribution of failure, Korean students would perform more accurately on the reasoning task than Canadian students, and given higher ability attribution of success, Canadian students may perform better or at least equally as well as Korean students. A Total of 120 grade seven students (60 Canadian and 60 Korean) from a middle-class community from Korea and Canada participated in the computerized experimental tasks. The research design involved two culture groups (Canadian and Korean) and three outcome feedback (control, failure, and success), as independent variables, and the number of instances, response rate and accuracy on the inductive reasoning tasks as dependent variables. Findings of this study indicate that Canadian culture may not be defined as more individualistic than Korean culture. The study results did not provide a clear cut distinction of collectivistic vs. individualistic cultures between Korean and Canadian cultures. In terms of attribution patterns, both culture groups showed similar patterns, but different from Weiner's theory of motivation, not only effort but also ability attribution influenced positively the accuracy of performance on the subsequent task upon receiving failure feedback. Given failure feedback, Korean grade seven students performed better, while Canadian counterparts' performance level on the subsequent task deteriorated with failure feedback. Further research on cross-cultural study of attribution theory has been suggested along with educational implications.

description: We construct an action of the braid group B_N on the twisted quantized enveloping algebra U'_q(o_N) where the elements of B_N act as automorphisms. In the classical limit q -> 1 we recover the action of B_N on the polynomial functions on the space of upper triangular matrices with ones on the diagonal. The action preserves the Poisson bracket on the space of polynomials which was introduced by Nelson and Regge in their study of quantum gravity and re-discovered in the mathematical literature. Furthermore, we construct a Poisson bracket on the space of polynomials associated with another twisted quantized enveloping algebra U'_q(sp_{2n}). We use the Casimir elements of both twisted quantized enveloping algebras to re-produce some well-known and construct some new polynomial invariants of the corresponding Poisson algebras.

description: Due to the incompatibility of the nonlinear realization of superconformal symmetry and dilatation symmetry with the dilaton as the compensator field, in the present paper it shows an alternative mechanism of spontaneous breaking the N=2 superconformal symmetry to the N=0 case. By using the approach of nonlinear transformations it is found that it leads to a space-filling brane theory with Weyl scale W(1,3) symmetry. The dynamics of the resulting Weyl scale invariant brane, along with that of other Nambu-Goldstone fields, is derived in terms of the building blocks of the vierbein and the covariant derivative from the Maurer-Cartan oneforms. A general coupling of the matter fields localized on the brane world volume to these NG fields is also constructed.

Looking after country : examining conditions for effective community-based natural resource management in Aboriginal Australia

description: Over the last few decades Aboriginal land management (ALM) has received increased interest and investment as a strategy to both conserve Australia's environment and assist in improving Aboriginal livelihoods. Yet thirty years of international community based natural resource management (CBNRM) experience shows that attempting to combine conservation and livelihood goals and integrate local knowledge and interests into environmental management is a serious challenge, particularly in areas involving Indigenous people. Based on a case study with Warlpiri people from the Southern Tanami region of Central Australia, this research examined conditions for effective CBNRM in remote Aboriginal Australia, that which promotes both livelihood and environmental outcomes and equitably integrates Indigenous knowledge into conservation. Findings from this research show that a major challenge to CBNRM in remote Australia is the limited recognition and reconciliation of the ontological differences that exist in this context. A key contribution of this thesis is in elucidating the pivotal role of brokers, the individuals who carry primary responsibility for mediating ontological differences at the cultural interface of ALM (usually known as 'coordinators' or 'facilitators'). This research explores the challenges brokers face and the dependence on non-Aboriginal brokers in Central Australian ALM, highlighting the task of navigating differing systems of accountability at the cultural interface. This research shows that supporting and investing in cross-cultural partnerships at the local level is essential for improved CBNRM in Aboriginal Australia. It implies the need for greater re-examination of the human-environment relationship in CBNRM theory and policy. Overall, this research highlights the importance of acknowledging process, relationships and inherent power dynamics for effective CBNRM, and indicates that Aboriginal people use the term 'two-ways' in an attempt to focus ALM discourse on these issues.

description: The thesis examines the manuscript Laon, Bibliothèque Municipale, MS 422 (L) and the contents of the astronomical and computistical compilation De astronomia et compoto held therein. The central focus was placed on the chapters containing materials from the Hiberno-Latin tract on the divisions of time, De diuisionibus temporum (DDT) with the aim of revealing the different strands of textual strata which make up these chapters. The thesis makes two significant contributions to knowledge. Firstly, it offers an analysis of the DDT chapters of the compilation in L, whose composition, it is argued, was the work of an Irish scholar operating on the continent in the last quarter of the eighth century. The in-depth analysis of a selection of L’s DDT chapters demonstrates the use of two different DDT tracts, and the elements of authorial contribution repeatedly align with Irish or Irish-associated scholarship of the eighth century. Secondly, the thesis contributes to the evolving understanding of the wider DDT tradition. Using the corpus of manuscript witnesses gathered by Bisagni in his 2019 study of DDT, the ‘expanded’ versions are used as comparanda for L and to illustrate the intersection of textual materials found in circulation during the Carolingian period, but which were distinct from the conventional and more commonly transmitted Standard DDT. This study argues that DDT should not be regarded as a single text, since, as demonstrated in this study, there were at least four distinct DDT tracts in circulation by the early ninth century. Accordingly, this thesis aims to contribute towards our understanding of the reception and transmission of Irish and Irish-influenced scholarly culture on the Carolingian continent.

Scholastes hirtiventris

description: Scholastes hirtiventris, new species. Male and female. A black species much like S. distigma Hendel, but differing from it and any other species known to me in having the large discal abdominal plate of the female furnished with dense long stiff hairs that are sparser basally. Head testaceous yellow, black on occiput except margin, two broad frontal bands as in S. aitapensis, a large mark on genae, a narrow line across lower extremities of facial foveae, a spot between base of each antenna and eye and another on central facial carina between antenna! bases. Antennae red, third segment dark on upper edge; palpi red. Frons a little longer than its anterior width, slightly narrowed behind; anterior carina distinct; bristles normal. Arista long haired to near apex, without apical pallette. Thorax black, humeri yellow, with a black spot, the usual pale yellow sublateral lines conspicuous, as is also the one around the apex of scutellum and one on upper margin of pleura. Supra-alar bristle strong; dorsocentrals 2 pairs; prescutellar pair of acrostichals as strong as posterior dorsocentral pair. Lqgs black, fore coxae brown, basal segment of all tarsi except its extreme apex whitish yellow. Wings grayish hya!ine, with blackish brown marks as follows: a fascia from basal half of the stigma passing through discal cell before middle, and not attaining hind margin, another fascia from apex of first vein passing over outer cross vein and divided from middle of latter to hind margin, a large subquadrate mark over apical fourth of second vein that extends backward over fourth vein and usually forks from there to hind margin, a spot in wing tip that does not extend entirely to edge of wing, a partial streak from costa to inner cross vein, and some spots in basal third of wing. Fifth vein bare. Abdomen black, with distinct blue tinge. Tergites in male with numerous short black hairs, in female, the large dorsal plate has dense, long, stiff, apically directed black hairs except basally, and in this sex, membrane between large plate and sternites also densely covered with rather shorter stiff black hairs. Length, 7-8 mm. Agana, May 25, 0. H. Swezey, type female; Ritidian Pt., April 15, Bryan, allotype male. The description of the wing markings is drawn from the wings of the male as those of the female are rather badly torn.

description: The Heusler compound ScInAu$_2$ was previously reported to have a superconducting ground state with a critical temperature of 3.0 K. Recent high throughput calculations have also predicted that the material harbors a topologically non-trivial band structure similar to that reported for beta-PdBi$_2$. In an effort to explore the interplay between the superconducting and topological properties properties, electrical resistance, magnetization, and x-ray diffraction measurements were performed on polycrystalline ScInAu$_2$. The data reveal that high-quality polycrystalline samples lack the super-conducting transition present samples that have not been annealed. These results indicate the earlier reported superconductivity is non-intrinsic. Several compounds in the Au-In-Sc ternary phase space (ScAu$_2$, ScIn$_3$, and ScInAu$_2$) were explored in an attempt to identify the secondary phase responsible for the non-intrinsic superconductivity. The results suggest that elemental In is responsible for the reported superconductivity in ScInAu$_2$.

description: A microscopic model is constructed which is able to describe multiple magnetic flux transitions as observed in recent ultra-low temperature tunnel experiments on an aluminum superconducting ring with normal metal - insulator - superconductor junctions [Phys. Rev. B \textbf{70}, 064514 (2004)]. The unusual multiple flux quantum transitions are explained by the formation of metastable states with large vorticity. Essential in our description is the modification of the pairing potential and the superconducting density of states by a sub-critical value of the persistent current which modulates the measured tunnel current. We also speculate on the importance of the injected non-equilibrium quasiparticles on the stability of these metastable states.

description: Josephson junctions based on InAs semiconducting nanowires and Nb superconducting electrodes are fabricated in-situ by a special shadow evaporation scheme for the superconductor electrode. Compared to other metallic superconductors such as Al, Nb has the advantage of a larger superconducting gap which allows operation at higher temperatures and magnetic fields. Our junctions are fabricated by shadow evaporation of Nb on pairs of InAs nanowires grown selectively on two adjacent tilted Si (111) facets and crossing each other at a small distance. The upper wire relative to the deposition source acts as a shadow mask determining the gap of the superconducting electrodes on the lower nanowire. Electron microscopy measurements show that the fully in-situ fabrication method gives a clean InAs/Nb interface. A clear Josephson supercurrent is observed in the current-voltage characteristics, which can be controlled by a bottom gate. The excess current of 0.68 indicates a high junction transparency. Under microwave radiation, pronounced integer Shapiro steps are observed suggesting a sinusoidal current-phase relation. Owing to the large critical field of Nb, the Josephson supercurrent can be maintained to magnetic fields exceeding 1 T. Our results show that in-situ prepared Nb/InAs nanowire contacts are very interesting candidates for superconducting quantum circuits requiring large magnetic fields.

description: For parents of young children and adolescents, the digital age has introduced many new challenges, including excessive screen time, inappropriate online content, cyber predators, and cyberbullying. To address these challenges, many parents rely on numerous parental control solutions on different platforms, including parental control network devices (e.g., WiFi routers) and software applications on mobile devices and laptops. While these parental control solutions may help digital parenting, they may also introduce serious security and privacy risks to children and parents, due to their elevated privileges and having access to a significant amount of privacy-sensitive data. In this paper, we present an experimental framework for systematically evaluating security and privacy issues in parental control software and hardware solutions. Using the developed framework, we provide the first comprehensive study of parental control tools on multiple platforms including network devices, Windows applications, Chrome extensions and Android apps. Our analysis uncovers pervasive security and privacy issues that can lead to leakage of private information, and/or allow an adversary to fully control the parental control solution, and thereby may directly aid cyberbullying and cyber predators.
