description: The AMIGA project aims to build a well defined and statistically significant reference sample of isolated galaxies in order to estimate the environmental effects on the formation and evolution of galaxies. The goal of this paper is to provide a measure of the environment of the isolated galaxies in the AMIGA sample, quantifying the influence of the candidate neighbours identified in our previous work and their potential effects on the evolution of the primary galaxies. Here we provide a quantification of the isolation degree of the galaxies in this sample. Our starting sample is the Catalogue of Isolated Galaxies (CIG). We used two parameters to estimate the influence exerted by the neighbour galaxies on the CIG galaxy: the local number density of neighbour galaxies and the tidal strength affecting the CIG galaxy. We show that both parameters together provide a comprehensive picture of the environment. For comparison, those parameters have also been derived for galaxies in denser environments such as triplets, groups and clusters. The CIG galaxies show a continuous spectrum of isolation, as quantified by the two parameters, from very isolated to interacting. The fraction of CIG galaxies whose properties are expected to be influenced by the environment is however low (159 out of 950 galaxies). The isolated parameters derived for the comparsion samples gave higher values than for the CIG and we found clear differences for the average values of the 4 samples considered, proving the sensitivity of these parameters. The environment of the galaxies in the CIG has been characterised, using two complementary parameters quantifying the isolation degree, the local number density of the neighbour galaxies and the tidal forces affecting the isolated galaxies.

Evolution of a Mode of Oscillation Within Turbulent Accretion Disks

description: We investigate the effects of subsonic turbulence on a normal mode of oscillation [a possible origin of the high-frequency quasi-periodic oscillations (HFQPOs) within some black hole accretion disks]. We consider perturbations of a time-dependent background (steady state disk plus turbulence), obtaining an oscillator equation with stochastic damping, (mildly) nonlinear restoring, and stochastic driving forces. The (long-term) mean values of our turbulent functions vanish. In particular, turbulence does not damp the oscillation modes, so `turbulent viscosity' is not operative. However, the frequency components of the turbulent driving force near that of the mode can produce significant changes in the amplitude of the mode. Even with an additional (phenomenological constant) source of damping, this leads to an eventual `blowout' (onset of effects of nonlinearity) if the turbulence is sufficiently strong or the damping constant is sufficiently small. The infrequent large increases in the energy of the mode could be related to the observed low duty cycles of the HFQPOs. The width of the peak in the power spectral density (PSD) is proportional to the amount of nonlinearity. A comparison with observed continuum PSDs indicates the conditions required for visibility of the mode.

description: This thesis studies methods to reduce latency in multi-user Augmented Reality (AR) environments, particularly focusing on applications over wireless Local Area Networks (WLANs). The two methods were proposed and evaluated: Dedicated AR Networks (DARN) and LAN-gaming Inspired Local Host Networks. DARN has been demonstrated as an effective approach to decrease latency and packet loss in AR traffic over WLANs, by prioritizing AR data through VLAN segmentation and optimizing network infrastructure. LAN Gaming-Inspired Techniques highlighted the benefits of localized processing and peer-to-peer communication models. These techniques, mimicking the low-latency environment in LAN gaming, reduced latency, particularly for internal server communications within AR applications. Combining DARN and LAN local host technology was proved to further enhance latency reduction.

description: Epigenetic mechanisms such as histone methylation are considered as one of the most important mediators that control stem cell behaviors such as proliferation, senescence and differentiation. G9a, a histone methyltransferase, has recently generated intense attention as potential target for controlling many diseases such as cancers. The aim of the present study was to evaluate the effect of in vivo administration of A366, a G9a inhibitor, on proliferative and differentiation potential of bone marrow-derived mesenchymal stem cells (BM-MSCs). We inhibited G9a using intraperitoneally administration of A366, and we evaluated BM-MSC proliferation and differentiation behaviors in vitro. Colony formation assay of BM-MSCs at primary culture showed that in vivo administration of A366 reduced the colony forming capacity of BM-MSCs. Moreover, PDT of BM-MSC isolated from A366-treated rats was higher than control, especially in the early passages. BM-MSC isolated from A366-treated rats showed higher adipogenic potential compared to the control at the early passages as determined by gene expression and Oil Red staining. Whereas, osteogenic potential of BM-MSC isolated from A366-treated rats was lower than control, especially at early passages. Our results suggest that the epigenetic modifier such as A366, which seems to be a therapeutic approach for controlling diseases such as cancer, might also influence the proliferation and differentiation capacity of MSCs both in vitro and in vivo. Moreover, epigenetic modifying chemicals seem to be a strategy to manipulate MSC expansion capacity and differentiation propensity, as well as to efficiently involvement of MSCs in tissue homeostasis, cell-based therapy and tissue engineering.

description: Cephennium jonicum group
Cephennium jonicum, which was previously represented by two named subspecies, the nominal subspecies from Corfu and C. jonicum petraeum APFELBECK, 1911 from Bosnia-Herzegovina and Croatia, belongs to a group of species characterized by an aedeagus with a bulbous capsule and with two minute apico-median internal structures. An examination of material from various regions in Greece (including Corfu) revealed that these structures differ between populations. As a result of their small size, the observed differences are, of course, less pronounced to the human eye than those between aedeagi of species belonging to other groups with larger internal structures. In addition, the aedeagi significantly differ in size. Moreover, a representative of the C. jonicum with similarly small internal structures of constantly different shape was recently discovered also in Turkey (ASSING & MEYBOHM in press). Since, finally, there is neither zoogeographic nor morphological evidence (transitional conditions) suggesting that the differences found in the C. jonicum group should be attributed to intersubspecific rather than interspecific variation, C. jonicum and allied taxa (including C. petraeum) are regarded as distinct species. Besuchet (unpublished notes) examined another undescribed species from the Croatian island Mljet ("Meleda"); the internal structures of the aedeagus are illustrated in Fig. 50.
Besuchet (unpublished notes) examined five males and two females of C. petraeum ("Neum a.M., Herceg.", "Pravno, Hercegov", "Hrasno") deposited in HNHM, NHMW, coll. Dodero, coll. Cauchois, and in his own collection. The internal structures of the aedaeagus of C. petraeum are illustrated in Fig. 49.

description: We present the results of our search for variable stars using the long-term Las Cumbres Observatory (LCO) monitoring of white dwarf ZTF J0139+5245 with the two 1.0-m telescope nodes located at McDonald Observatory using the Sinistro imaging instrument. In this search, we find 38 variable sources, of which 27 are newly discovered or newly classified (71%) based on comparisons with previously published catalogs, thereby increasing the number of detections in the field-of-view under consideration by a factor of $\approx$ 2.5. We find that the improved photometric precision per-exposure due to longer exposure time for LCO images combined with the greater time-sampling of LCO photometry enables us to increase the total number of detections in this field-of-view. Each LCO image covers a field-of-view of $26' \times 26'$ and observes a region close to the Galactic plane ($b = -9.4^\circ$) abundant in stars with an average stellar density of $\approx 8$ arcmin$^{-2}$. We perform aperture photometry and Fourier analysis on over 2000 stars across 1560 LCO images spanning 537 days to find 28 candidate BY Draconis variables, 3 candidate eclipsing binaries of type EA, and 7 candidate eclipsing binaries of type EW. In assigning preliminary classifications to our detections, we demonstrate the applicability of the Gaia color-magnitude diagram (CMD) as a powerful classification tool for variable star studies.

description: We propose and study a continuum model for the dynamics of amorphizable surfaces undergoing ion-beam sputtering (IBS) at intermediate energies and oblique incidence. After considering the current limitations of more standard descriptions in which a single evolution equation is posed for the surface height, we overcome (some of) them by explicitly formulating the dynamics of the species that transport along the surface, and by coupling it to that of the surface height proper. In this we follow recent proposals inspired by ``hydrodynamic'' descriptions of pattern formation in aeolian sand dunes and ion-sputtered systems. From this enlarged model, and by exploiting the time-scale separation among various dynamical processes in the system, we derive a single height equation in which coefficients can be related to experimental parameters. This equation generalizes those obtained by previous continuum models and is able to account for many experimental features of pattern formation by IBS at oblique incidence, such as the evolution of the irradiation-induced amorphous layer, transverse ripple motion with non-uniform velocity, ripple coarsening, onset of kinetic roughening and other. Additionally, the dynamics of the full two-field model is compared with that of the effective interface equation.

description: 2b. Euphorbia clivicola subsp. calcritica Bruyns, subsp. nov.
This new subspecies differs from subsp. clivicola by the slightly rhizomatous habit, the longer spines, the pale stripe along the middle of the branches and the brownish yellow cyathial glands.
Type:— SOUTH AFRICA. Limpopo. 20 km from Zebediela towards Roedtan (2429AD), 1030 m, 31 October 2011, Bruyns 12045 (holotype BOL!).
Slightly rhizomatous succulent forming small clusters of branches to 150 mm in diam. Branches 40–60(–150) × 6−10 mm, subcylindrical, grey-green to brownish green with pale stripe between rows of tubercles; tubercles with spine-shields 5–10 × 1–3 mm, ± 3 mm broad above spines and 4–8 mm long slender and finely acute below spines, bearing 2 spreading initially reddish brown (later grey) spines 5–12 mm long; leaf-rudiments ± 0.5 × 0.7–1.2 mm, erect, fleeting, ovate, with irregular tiny stipular prickles ± 0.25 mm long. Cyathia and glands slightly brownish yellow with reddish bracts.
Distribution & Habitat: — Subsp. calcritica has only been recorded between Zebediela and Roedtan (Fig. 2), though it is likely to occur more widely in this area. At the type locality it grows in flat patches with much calcritic rubble on and beneath the surface, among short bushes (mostly <20 cm tall) between larger and scattered clumps of trees.
Discussion: —This new subspecies has been known since a record made by Frank Bayer in 1942 at PRE (photo only), but there are no specimens other than the type. It shares with subsp. clivicola the prominent tubercles which are not joined into angles, differing from subsp. clivicola by the slightly rhizomatous habit, the paler markings on the branches and the brownish yellow cyathial glands.

description: We summarize the most important arguments why a perturbative description of finite-temperature QCD is unlikely to be possible and review various well-established approaches to deal with this problem. Then, using a recently proposed method, we investigate nonperturbative contributions to the QCD pressure and other observables (like energy, anomaly and bulk viscosity) obtained by imposing a functional cutoff at the Gribov horizon. Finally, we discuss how such contributions fit into the picture of consecutive effective theories, as proposed by Braaten and Nieto, and give an outline of the next steps necessary to improve this type of calculation.

description: Time-sharing Experiments for the Social Sciences (TESS) offers researchers the opportunity to capture the internal validity of experiments. Investigators submit proposals, and TESS fields successful proposals for free on a representative sample of adults in the United States. This experiment was conducted to investigate the impact that the architectural designs of police stations have on public perceptions and behavioral intent. Half of the participants were randomly assigned to view an image set of one of three hostile buildings and the other half were assigned to view an image set of one of three welcoming buildings. A total of 732 respondents participated. Respondents answered measures of their emotional reaction to the building viewed at a distance and up-close, their level of confidence in their criminal complaint being taken seriously, perceptions of the level of professionalism that individuals in the building possess, and likelihood of entering into the police building to report the crime. After treatment, respondents answered questions about their perceptions of the criminal justice system. This allowed for comparison of affective states and behaviorally relevant perceptions across building designs and respondent demographics.

description: Over the past few years, my students have increasingly claimed that they are overworked and that they don’t have a life. They are worried about their grades, their ability to find a job after graduation and repay their student loans. In this article, I grapple with this growing anxiety and stress that I have witnessed among my students. I explore the correlation between the neoliberalization of education, the ideology of human capital and student state of panic and anxiety. I argue that the neoliberal education reform has intensified overwork and exhaustion, as students have internalized the logic that they are human capital, constantly needing to compete and increase their value on the market. I further call upon the humanities to question the neoliberal work ethic and fight for a higher education whose ultimate objective is not the creation of human capital.

description: We study semileptonic B meson decays B to K_1(1270) l^+ l^- and K_1(1400) l^+ l^- (l=e, mu, tau), where the strange P-wave mesons, K_1(1270) and K_1(1400), are the mixtures of the K_{1A} and K_{1B}, which are the 1^3P_1 and 1^1P_1 states, respectively. We show that the ratio R_l = Br(B to K_1(1400) l^+ l^-)/Br(B to K_1(1270) l^+ l^-), insensitive to new-physics parameters, is suitable for determining the K_1(1270)-K_1(1400) mixing angle, theta_{K_1}. The forward-backward asymmetry shows a weak theta_{K_1}-dependence for B to K_1(1270) mu^+ mu^-, but relatively strong for B to K_1(1400) mu^+ mu^-. We investigate model-independent new-physics corrections to operators relevant to the b to s l^+ l^- electroweak-penguin and weak-box diagrams. Furthermore, for the B to K_1(1270) mu^+ mu^- decay the position of the forward-backward asymmetry zero, which is almost independent of the value of theta_{K_1}, can be dramatically changed under variation of new-physics parameters.

Description: Body length 1.3-1.4 mm; antenna 0.7 mm long. Habitus (Fig. 1) robust (body rather broad and strongly convex in cross-section). Body reddish-brown to dark-brown with the elytra at least slightly darker than head and pronotum.
Eyes composed of approximately ten ommatidia with pigmentation. Antenna with antennomeres V and VII longer and more oblong than antennomeres VI and VIII; antennomeres X approximately 1.5 times as broad as long and XI approximately twice as long as broad.
Pronotum approximately 1.2 times as broad as long, strongly convex in cross-section, posteriorly with weakly keel-shaped median elevation; punctation very fine.
Elytra broader than pronotum, strongly convex in cross-section, anteriorly each with a transverse impression with tomentose whitish pubescence; punctation very fine.
♂: protibia apically strongly excavate and curved; metaventrite extensively and shallowly impressed; aedeagus (Figs 17-18) 0.38-0.40 mm long; median lobe subapically dilated and apically with a short median projection in ventral view; internal structures distinctive; parameres curved and slender, nearly reaching apex of median lobe, with moderately long apical seta.
Comparative notes: Based on external (robust habitus; body strongly convex in cross-section) and the male primary and secondary sexual characters (protibia apically curved and excavate; median lobe of aedeagus long and slender, apically with a median process in ventral view; parameres curved and with relatively long apical seta), C. dilatatum belongs to the C. perispinctum group (see ASSING & MEYBOHM in press). It is reliably distinguished from other species of this group only by the shape and internal structures of the aedeagus.
Distribution and natural history: The type specimens were found in two localities in Oros Pangéo (Northeast Greece), a mountain remarkably rich in endemic species. They were sifted from leaf litter and fern roots in beech forests at altitudes of 1080 and 1410 m.

A test of social identity theory : intergroup discrimination and self-esteem in the minimal group paradigm
Creators: name: Lemyre, Louise
Publisher: name: University of British Columbia
Year: 2010

description: To study categorization effects in an experimental context the minimal group paradigm has been designed by Henri Tajfel. Subjects are categorized into two groups on an ad hoc, trivial criterion and asked to allocate points to two anonymous persons. The reliable finding in this minimal situation consists of intergroup discrimination; i.e. ingroup favoritism plus maximum intergroup differentiation. Social Identity Theory attempts to explain such intergroup discrimination in the 'real world' as well as in the context of the minimal group paradigm. The theory postulates a basic need for positive self-esteem and a process of social identification. In situations of social categorization, social identity (i.e. the group membership) can mediate self-esteem. Relative positive group distinctiveness in favor of the ingroup is sought through competitive social comparison and can be achieved by intergroup discrimination. It consequently leads to higher self-esteem. This research was aimed at verifying experimentally whether or not self-esteem was indeed involved in intergroup discrimination, and at which of several possible levels: social categorization, cognitive differentiation of the ingroup and the outgroup, or the actual competitive discrimination against the outgroup. Eight conditions concurrently run and randomly assigned among 135 undergraduates manipulated: (a) social categorization, (b) intergroup discrimination via a point allocation task, and (c); the moment at which self-esteem was assessed; all within the minimal group paradigm. Four conditions determined a 2x2 factorial design and four others added specific supplementary controls. The dependent measures included Rosenberg's Self-Esteem scale, the Twenty Statements test, nine semantic differential scales, Sherwood's Self-Concept Inventory, and a single global rating of self-esteem. Overall the hypothesis was supported. Intergroup discrimination contributed to self-esteem as predicted by Social Identity Theory. A significant interaction effect was found using a two-way MANOVA on the 2x2 design. Specifically, categorized and discriminative subjects were equivalent to baseline subjects on self-esteem and they were higher than those who were either categorized and did not do the point allocation task, or were not categorized but did the task. The supplementary conditions confirmed that for categorized subjects, intergroup discrimination benefitted self-esteem. The results suggested that threat was perceived for those who were facing an unresolved social comparison situation which lowered their self-esteem.

description: 4. Euphorbia louwii Leach (1980: 207).
Type:— SOUTH AFRICA. Transvaal (Limpopo): ± 14 km east of Marken, 900 m, 1 November 1975, Leach et al. 15555 (holotype PRE!, isotypes K!, SRGH).
Discussion:— Euphorbia louwii is known from a small area around the hamlet of Marken, north-east of the Waterberg in Limpopo Province, South Africa. It is most easily distinguished from the other members of the E. schinzii -complex by the 5- to 7-angled branches and the considerably longer and more slender leaf-rudiments. Five spines and prickles per spine-shield is typical of E. louwii and is also found occasionally in E. aeruginosa. The two also share a very similar colour of the branches and spine-shields, though the pale streak between the angles in E. louwii is missing in E. aeruginosa.

description: The decreasing importance of state evoked the debate about the role of professional networks in the IR. The epistemic communities also became relevant actors of international politics. This paper specifies conditions of how they involve in the political negotiations about poverty eradication within the frame of the 2030 Agenda. The paper uses a social constructivist concept of the epistemic community which explains the relation between its professional coherence and its involvement in the political negotiations. The epistemic communities have involved in the political negotiations about poverty eradication, but this has not been reflected in related scholarly literature yet. The analysis confirms the link between the weak inner professional coherence of a network associating an epistemic community and its weak ability to spread a belief during political negotiations. It also reveals relationship between higher political support and higher level of consideration of the beliefs of governmental networks associating epistemic communities in political negotiations that were created by resolutions of the UNGA and the ECOSOC.

Type material: Holotype ♂: " GR-Makedonia, Umg. Litóhoro, Mt. Olimbos, O-Seite ca. 500 m, 19.5.87, leg. Brachat / Holotypus ♂ Cephennium olympicum sp. n. det. V. Assing 2020" (cAss). Paratypes: 1♂, 1♀: same data as holotype (cAss).
Etymology: The specific epithet is an adjective derived from Olympos, the name of the mountain where the type locality is situated.
Description: Body length 1.3-1.4 mm; antenna approximately 0.75 mm long. Colouration: head and pronotum reddish-brown; elytra blackish-brown. Habitus (Fig. 2), size, and other external characters as in C. dilatatum, except as follows:
Antennae more slender; antennomeres IX and X barely 1.5 times as broad as long. Pronotum with very indistinct median elevation posteriorly.
♂: protibia subapically strongly excavate, only very weakly curved, and apically distinctly dilated; aedeagus (Fig. 19) 0.37-0.38 mm long; median lobe apically acute; internal structures rather massive, rather strongly sclerotized, and of distinctive shapes; parameres slender, not reaching apex of median lobe, with rather long apical seta.
Comparative notes: Like C. dilatatum, C. olympicum belongs to the C. perispinctum group. It differs from other representatives of this group particularly by the modifications of the male protibiae and by the structure of the aedeagus. From C. assingi, with which it shares a similar shape of the aedeagus, it differs in the internal structures of the aedeagus and by the modifications of the male protibiae.
Distribution and natural history: Thetypelocalityissituated in eastern slopes of Oros Olympos at an altitude of approximately 500 m.

description: In this paper, the isodiametric problem for centrally symmetric convex bodies in the Euclidean d-space R^d containing no interior non-zero point of a lattice L is studied. It is shown that the intersection of a suitable ball with the Dirichlet-Voronoi cell of 2L is extremal, i.e., it has minimum diameter among all bodies with the same volume. It is conjectured that these sets are the only extremal bodies, which is proved for all three dimensional and several prominent lattices.

description: Magneto-optical imaging and magnetization measurements were applied to investigate local formation of superconducting phase effected by a random neck synthesis in Y-Ba-Cu-O system. Polished pellets of strongly inhomogeneous ceramic samples show clearly the appearance of superconducting material in the intergrain zones of binary primary particles reacted under different conditions. Susceptibility measurements allows evaluation of superconducting critical temperature, which turned out to be close to that of optimally doped YBCO.

description: We carry out a detailed analysis of sparticle mass spectrum in supersymmetric grand unified theories. We consider the spectroscopy of the squarks and sleptons in SU(5) and SO(10) grand unified theories, and show how the underlying supersymmetry breaking parameters of these theories can be determined from a measurement of different sparticle masses. This analysis is done analytically by integrating the one-loop renormalization group equations with appropriate boundary conditions implied by the underlying grand unified gauge group. We also consider the impact of non-universal gaugino masses on the sparticle spectrum, especially the neutralino and chargino masses which arise in supersymmetric grand unified theories with non-minimal gauge kinetic function. In particular, we study the interrelationships between the squark and slepton masses which arise in grand unified theories at the one-loop level, which can be used to distinguish between the different underlying gauge groups and their breaking pattern to the Standard Model gauge group. We also comment on the corrections that can affect these one-loop results.
