description: We present results from Chandra and XMM-Newton observations of the bright group of galaxies HCG 62. There are two cavities at about 30'' northeast and 20'' southwest of the central galaxy in the Chandra image. The energy spectrum shows no significant change in the cavity compared with that in the surrounding region. The radial X-ray profile is described by a sum of 3-beta components with core radii about 2, 10, and 160 kpc, respectively. We studied radial distributions of temperature and metal abundance with joint spectral fit for the Chandra and XMM-Newton data, and two temperatures were required in the inner r< 2' (35 kpc) region. The sharp drop of temperature at r about 5' implies the gravitational mass density even lower than the gas density, suggesting the gas may not be in hydrostatic equilibrium. Fe and Si abundances are 1-2 solar at the center and drop to about 0.1 solar at r about 10'. O abundance is less than 0.5 solar and shows a flatter profile. Observed metal distribution supports the view that iron and silicon are produced by type Ia supernova in the central galaxy, while galactic winds by type II supernova have caused wide distribution of oxygen. The supporting mechanism of the cavity is discussed. Pressure for the sum of electrons and magnetic field is too low to displace the hot group gas, and the required pressure due to high energy protons are nearly 700 times higher than the electron pressure. This leaves the origin of the cavities a puzzle, and we discuss other possible origins of the cavities.

description: This work generalizes the theory of arithmetic local constants, introduced by Mazur and Rubin, to better address abelian varieties with a larger endomorphism ring than $\mathbb{Z}$. We then study the growth of the $p^\infty$-Selmer rank of our abelian variety, and we address the problem of extending the results of Mazur and Rubin to dihedral towers $k\subset K\subset F$ in which $[F:K]$ is not a $p$-power extension.

description: We report the observation of strong exciton-photon coupling in a ZnSe based microcavity fabricated using epitaxial liftoff. Molecular beam epitaxial grown ZnSe/Zn$_{0.9}$Cd$_{0.1}$Se quantum wells with a one wavelength optical length at the exciton emission were transferred to a SiO$_2$/Ta$_2$O$_5$ mirror with a reflectance of 96% to form finesse matched microcavities. Analysis of our angle resolved transmission spectra reveals key features of the strong coupling regime: anticrossing with a normal mode splitting of $23.6 meV$ at $20 K$; composite evolution of the lower and upper polaritons; and narrowing of the lower polariton linewidth near resonance. The heavy hole exciton oscillator strength per quantum well is also deduced to be $1.78 \times 10^{13} cm^{-2}$.

Spin-two fields and general covariance
Creators: name: Heiderich, Karen Rachel
Publisher: name: University of British Columbia
Year: 2011

description: It has long been presumed that any consistent nonlinear theory of a spin-two field must be generally covariant. Using Wald's consistency criteria, we exhibit classes of nonlinear theories of a spin-two field that do not have general covariance. We consider four alternative formulations of the spin-two equations. As a first example, we consider a conformally invariant theory of a spin-two field coupled to a scalar field. In the next two cases, the usual symmetric rank-two tensor field, γab, is chosen as the potential. In the fourth case, a traceless symmetric rank-two tensor field is used as the potential. We find that consistent nonlinear generalization of these different formulations leads to theories of a spin-two field that are not generally covariant. In particular, we find types of theories which, when interpreted in terms of a metric, are invariant under the infinitesimal gauge transformation γab→γab + ∇ (a∇[symbol omitted]K[symbol omitted]), where Kab is an arbitrary two-form field. In addition, we find classes of theories that are conformally invariant. As a related problem, we compare the types of theories obtained from the nonlinear extension of a divergence- and curl-free vector field when it is described in terms of two of its equivalent formulations. We find that nonlinear extension of the theory is quite different in each case. Moreover, the resulting types of nonlinear theories may not necessarily be equivalent. A similar analysis is carried out for three-dimensional electromagnetism.

description: The project service monitoring is one of the essential aspects of a company that ensures all project activities running well. In the current digital transformation era, competition in the digital world makes several companies to used efficient system in their business process, for example the business process at PT. Gerbang Sinergi Prima (GSP). In the prior observation, the project monitoring activities in GSP still use conventional way, which often requires more time and risk like data redundancy. Hence, this study developed a Front-End website for the project service monitoring with Scrum method to emphasize the development process in a complex manner and allow user needs. Differ from the other studies, the system testing used in this study uses the black box and usability testing from four participants with system usability scale (SUS). The results of the black box test showed a perfect score in the result. In addition, the results of testing using SUS got an average score of 63.125 which means this system can be acceptable quite good by users.

description: Rendering tactile effects on a touch screen via electrovibration has many potential applications. However, our knowledge on tactile perception of change in friction and the underlying contact mechanics are both very limited. In this study, we investigate the tactile perception and the contact mechanics for a step change in friction under electrovibration during a relative sliding between finger and the surface of a capacitive touchscreen. First, we conduct magnitude estimation experiments to investigate the role of normal force and sliding velocity on the perceived tactile intensity for a step increase and decrease in friction, called as rising friction (RF) and falling friction (FF). To investigate the contact mechanics involved in RF and FF, we then measure the frictional force, the apparent contact area, and the strains acting on the fingerpad during sliding at a constant velocity under three different normal loads using a custom-made experimental set-up. The results show that the participants perceived RF stronger than FF, and both the normal force and sliding velocity significantly influenced their perception. These results are supported by our mechanical measurements; the relative change in friction, the apparent contact area, and the strain in the sliding direction were all higher for RF than those for FF, especially for low normal forces. Taken together, our results suggest that different contact mechanics take place during RF and FF due to the viscoelastic behavior of fingerpad skin, and those differences influence our tactile perception of a step change in friction.

Effects of serotonin type 3 receptor activity on receptive and proceptive behaviours in female rats
Creators: name: Tanco, Sheryl Anne
Publisher: name: University of British Columbia
Year: 2011

description: The neurotransmitter serotonin (5-HT) influences many centrally-mediated behaviours. In female rats, 5-HT affects the expression of lordosis, a behavioural index of sexual receptivity. Conflicting empirical evidence regarding the role of 5-HT, with respect to lordosis, and identification of subtypes of central 5-HT receptors led to formulation of the hypothesis that 5-HT plays a dual role with respect to female sexual behaviour. Evidence suggests that 5-HT₁[symbol omitted] receptors inhibit, while 5-HT₂ receptors facilitate lordosis. The recently identified central 5-HT₃ receptor affects the release of neurotransmitters such as dopamine, norepinephrine and acetylcholine; modulates the effects of opiates, amphetamine and nicotine; and influences anxiety, learning, nociception, nausea and vomiting. It remains to be determined whether 5-HT₃ receptors also influence reproductive activity. In female rats sexual activity is comprised of two types of behaviours: receptive (lordosis) and proceptive (ear wiggling, hopping and darting). In the current literature, lordosis stands as the primary measure; proceptive behaviours are seldom reported. The purpose of this thesis is to further characterize the 5-HT₃ receptor with respect to female reproductive activity and to increase the understanding of neurochemical factors which influence receptive and proceptive behaviours in female rats. The current series of experiments investigated the effects of 5-HT₃ agonists and antagonists, administered alone and in conjunction with morphine and apomorphine, on sexual behaviours in ovariectomized, steroid-primed female rats. The 5-HT₃ antagonists MDL 72222, ondansetron and ICS 205-930 failed to affect receptive or proceptive behaviours, although a trend towards a facilitatory effect was evident in the case of ondansetron. Similarly, the 5-HT3 agonists 1-phenylbiguanide and 2-methyl-serotonin, administered intracerebroventricularly, did not significantly influence female copulatory behaviours. While low doses of morphine significantly inhibited sexual activity, this inhibition was not attenuated by any of the 5-HT₃ antagonists. Likewise, apomorphine profoundly inhibited both receptive and proceptive behaviours, but these effects were not antagonized by ICS 205-930. Although these data do not support the idea that 5-HT3 receptors are influential in the modulation of female reproductive behaviours, consideration of various pharmacological and methodological factors caution against a premature conclusion in this regard.

Verso una pedagogia innovativa della lettura: codici testuali e codici digitali

Publisher: name: Studi sulla Formazione
Year: 2015

description: This paper presents a reflection on the subject of traditional reading and digital reading, and focuses on the pedagogical implications when moving from print to a digital reading environment. It stresses out the differences between the digital reading of the texts, such as the e-books, and the digital reading on the Internet. Based on the acquisitions coming mainly from the neuroscientific scope, it suggests the complexity of online reading is not favorable to the readers who are at the beginning of their path of literacy. The paper notes that for the novice read- ers is more appropriate to read both on printed page and on digital content that maintain largely the printing features - such as stability, linearity, the fulfillment of the content. These features attract the full attention of the reader and encour-age the development of cognitive processes at the base of a deep reading. These processes must be strengthened expecially at the beginning of the reading learning process.
The online reading can be addressed later, using metacognitive techniques and self-regulated strategies that accustom the reader to stop on a text and to monitor his/her comprehension, to resist a superficial reading, and to engage the research for a deeper meaning.
The article emphasizes the importance of integrating the two forms of reading and to promote the best of both literacies.

description: This paper investigates the initial boundary value problem for a non-stationary one-dimensional heat equation that simulates the temperature distribution in freshwater ice near the Earth's poles. The mathematical model has been constructed taking into account solid-liquid phase transitions. Data from meteorological stations were used to determine the model parameters, with the help of which the necessary physical and thermophysical characteristics of the computational domain were obtained. For the numerical solution of the problem, the finite volume method (FVM) was used. For the obtained periodic regime, the temperature versus depth dependences for each month were plotted, and the depth of the active layer, as well as the depth of zero annual amplitudes were found for each meteorological station. A forecast of the ice temperature regime for 2100 was modeled for three Representative Concentration Pathway (RCP) scenarios of global warming: moderate RCP2.6, corresponding to the current emissions of RCP7 and adopted at the Paris Agreement in 2015 RCP1.9. By analyzing the impact of an additional 0,5 degrees Celsius of warming on other areas, a reduction in the full range of risks to humanity and the planet as a whole becomes evident with the proper efforts of the global community. Thus, the conducted modeling has confirmed the need to reduce the rate of global warming.

description: OBJECTIVES: To define ultrasonographic patterns reflecting different states of Peyronie's disease (PD) and to use them to evaluate the natural history of the disease. MATERIAL AND METHODS: Diagnosis of PD was based on medical and sexual history, physical examination, intracavernosal injection test, and penile ultrasonography. Patients with penile fracture history were excluded from the study. Three groups were formed according to ultrasonographic patterns: solitary hyperechoic lesion without acoustic shadow (group A), moderately hyperechoic multiple scattered calcified lesions with acoustic shadows (group B), dense calcified hyperechoic plaque with acoustic shadow (group C). All patients entered a watchful waiting protocol for 1 yr followed by a new penile ultrasonography. RESULTS: Ninety-five 95 patients with PD were included in the study (mean age, 57.2+/-9.1 yr; mean duration of disease, 12.9+/-8.9 mo). Risk factors associated with cardiovascular disease were present in 79 of 95 patients (83.16%). Eleven (11.6%), 35 (36.8%), and 49 (51.6%) patients were classified into groups A, B and C, respectively. At the end of the study, in group A, reduction of fibrotic lesions and curvature angle was noticed in 9 of 11 (81.8%) patients, whereas plaque formation was noticed in 2 of 11 (18.2%) patients. In group B, plaque and curvature reduction was noticed in 15 of 35 (42.9%) and 12 of 35 (34.3%) respectively, whereas in the rest a dense calcified plaque was noticed. In group C, no ultrasonographic evidence of improvement was noticed; curvature angle was reduced in 4 of 49 (8.2%), owing to the extension of the plaque circumferentially. Significant hemodynamic changes were noticed at the two time points tested (30.53% diagnosed with vascular disease at baseline vs. 46.32% at the end of the study, p=0.03). CONCLUSIONS: Corporal ultrasonography in patients with PD allows objective evaluation and classification of disease. The density of echogenic areas and presence of acoustic shadows are predictors of disease stability

Relaxation paths for single modes of vibrations in isolated molecules

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A numerical simulation of vibrational excitation of molecules was devised, and used to excite computational models of common molecules into a prescribed, pure, normal vibration mode in the ground electronic state, with varying, controlable energy content. The redistribution of this energy (either non-chaotic or irreversible IVR) within the isolated, free molecule is then followed in time with a view to determining the coupling strength between modes. This work was triggered by the need to predict the general characters of the infrared spectra to be expected from molecules in interstellar space, after being excited by photon absorption or reaction with a radical. It is found that IVR from a pure normal mode is very "restricted" indeed at energy contents of one mode quantum or so. However, as this is increased, or when the excitation is localized, our approach allows us to isolate, describe and quantify a number of interesting phenomena, known to chemists and in non-linear mechanics, but difficult to demonstrate experimentally: frequency dragging, mode locking or quenching or, still, instability near a potential surface crossing, the first step to generalized chaos as the energy content per mode is increased.

description: Majorana bound states are zero-energy states predicted to emerge in topological superconductors and intense efforts seeking a definitive proof of their observation are still ongoing. A standard route to realize them involves antagonistic orders: a superconductor in proximity to a ferromagnet. Here we show this issue can be resolved using antiferromagnetic rather than ferromagnetic order. We propose to use a chain of antiferromagnetic skyrmions, in an otherwise collinear antiferromagnet, coupled to a bulk conventional superconductor as a novel platform capable of supporting Majorana bound states that are robust against disorder. Crucially, the collinear antiferromagnetic region neither suppresses superconductivity nor induces topological superconductivity, thus allowing for Majorana bound states localized at the ends of the chain. Our model introduces a new class of systems where topological superconductivity can be induced by editing antiferromagnetic textures rather than locally tuning material parameters, opening avenues for the conclusive observation of Majorana bound states.

Determination of Black Hole Mass in Cyg X-1 by Scaling of Spectral Index-QPO Frequency Correlation

Year: 2007

description: It is well established that timing and spectral properties of Galactic Black Hole (BH) X-ray binaries (XRB) are strongly correlated. In particular, it has been shown that low frequency Quasi-Periodic Oscillation (QPO) frequency - photon index correlation curves have a specific pattern. In a number of sources the shape of the index-low frequency QPO correlations are self-similar with a position offset in the QPO frequency-Gamma plane. Titarchuk & Fiorito presented strong theoretical and observational arguments that the QPO frequency values in this QPO frequency-Gamma correlation should be inversely proportional to M_{BH}. A simple translation of the correlation for a given source along the frequency axis leads to the observed correlation for another source. As a result of this translation one can obtain a scaling factor which is simply a BH mass ratio for these particular sources. This property of the correlations offers a fundamentally new method for BH mass determination in XRBs. Here we use the observed QPO-index correlations observed in three BH sources: GRO J1655-40, GRS 1915+105 and Cyg X-1. The BH mass of (6.3 +/- 0.5) M_Sun in GRO J1655-40 is obtained using optical observations. RXTE observations during the recent 2005 outburst yielded sufficient data to establish the correlation pattern during both rise and decay of the event. We use GRO J1655-40 as a standard reference source to measure the BH mass in Cyg X-1. We also revisit the GRS 1915+105 data as a further test of our scaling method. We infer the value of BH mass of (15.6 +/- 1.5) M_Sun in this source which is consistent with the previous BH mass estimate in GRS 1915 of (13.3 +/- 4) M_Sun. We obtain the BH mass in Cyg X-1 in the range (8.7 +/- 0.8) M_Sun.

For this aim an environemntal content analysis-focusing in forest-of the whole books of the primary school has been carried out. Also a questionnaire has been filled by 1219 pupils of 6th class, who live in urvan, semi-urban, plain and mountainous areas of Macedonia. According to the results, it has been find out that the satisfactory results of pupils in knowledge matters, have a significant improvement after their participation in programms of enviromental education. Also, the pupils who live in environmental decomposed areas appear to be more sensitive and are willing to undertake initiative for the salvation of our forests. Pupils who live in mountainous areas are very concerned about their inadiquate protection and talk about the need of taking measures for their protection. Taking under consideration, the results of the research, the major deficiences of school books and childrens' enthousiasm about forest, we created environmental material for the forest

In this paper we study the relationship between the functor which deforms a pair (\sF,σ), σ\in H^0(\sF), and the functor which deforms the corresponding pair (X,ξ) given as in the Serre correspondence. We prove that the scheme structure of e.g. the moduli scheme M_Y(P) of stable sheaves on a threefold Y at (\sF), and the scheme structure at (X) of the Hilbert scheme of curves on Y are closely related. Using this relationship we get criteria for the dimension and smoothness of M_Y(P) at (\sF), without assuming Ext^2(\sF,\sF) = 0. For reflexive sheaves on Y = \proj{3} whose deficiency module M = H_{*}^1(\sF) satisfies Ext^2(M,M) = 0 in degree zero (e.g. of diameter at most 2), we get necessary and sufficient conditions of unobstructedness which coincide in the diameter one case. The conditions are further equivalent to the vanishing of certain graded Betti numbers of the free graded minimal resolution of H_{*}^0(\sF). It follows that every irreducible component of M_{\proj{3}}(P) containing a reflexive sheaf of diameter one is reduced (generically smooth). We also determine a good lower bound for the dimension of any component of M_{\proj{3}}(P) which contains a reflexive stable sheaf with "small" deficiency module M.

description: The Harper-Hofstadter problem for two-dimensional electron gas with Rashba spin-orbit coupling subject to periodic potential and perpendicular magnetic field is studied analytically and numerically. The butterfly-like energy spectrum, spinor wave functions as well as the spin density and average spin polarization are calculated for actual parameters of semiconductor structure. Our calculations show that in two-dimensional electron gas subject to periodic potential and uniform magnetic field the effects of energy spectrum splitting caused by large spin-orbit Rashba coupling can be observed experimentally.

description: In this paper, inference for the parametric component of a semiparametric model based on sampling from the posterior profile distribution is thoroughly investigated from the frequentist viewpoint. The higher-order validity of the profile sampler obtained in Cheng and Kosorok [Ann. Statist. 36 (2008)] is extended to semiparametric models in which the infinite dimensional nuisance parameter may not have a root-$n$ convergence rate. This is a nontrivial extension because it requires a delicate analysis of the entropy of the semiparametric models involved. We find that the accuracy of inferences based on the profile sampler improves as the convergence rate of the nuisance parameter increases. Simulation studies are used to verify this theoretical result. We also establish that an exact frequentist confidence interval obtained by inverting the profile log-likelihood ratio can be estimated with higher-order accuracy by the credible set of the same type obtained from the posterior profile distribution. Our theory is verified for several specific examples.

Defining the Chinese other : White supremacy, schooling and social structure in British Columbia before 1923
Creators: name: Stanley, Timothy John
Publisher: name: University of British Columbia
Year: 2011

description: During the late nineteenth and early twentieth centuries, racism, in the form of white supremacy, shaped relations between whites and Chinese British Columbians. In resisting and accommodating to white supremacy, the Chinese were active participants, along with the members of the dominant society, in shaping these relations. White supremacy was consequently a dynamic system, one whose many parts were continually in flux, and whose central constructs—notions of "race" and British Columbia as "a White Man's province"—were largely political in nature. The thesis argues that white supremacy, as both ideology and organization, was deeply imbedded in British Columbia society. Exclusion based on "race" was incorporated into government institutions as they were remade at Confederation in an effort to enhance the power of white male property-owners. By the early twentieth century, ideological constructs of "the Chinaman" and "the Oriental" were used as foils in the creation of identities as "whites" and as "Canadians." The official public school curriculum transmitted these notions, while schools themselves organized supremacy in practice by imposing racial segregation on many Chinese students. In reaction, the Chinese created their own institutions and ideologies. While these institutions often had continuities with the culture of South China, the place of origin of most B.C. Chinese, they were primarily adaptations to the conditions of British Columbia, including the realities of racism. Chinese language schools played an especially important role in helping to create a Chinese merchant public separate from the dominant society. This public was at once the consequence of exclusion and the greatest community resource in resisting white supremacy. The study concludes by questioning the workability of contemporary anti-racist strategies which treat racism as a marginal phenomenon, or as merely a set of mistaken ideas. Instead, it suggests that such strategies must recognize that racism is one of the major structures of Canadian society.

description: Optically addressable spins in materials are important platforms for quantum technologies, such as repeaters and sensors. Identification of such systems in two-dimensional (2d) layered materials offers advantages over their bulk counterparts, as their reduced dimensionality enables more feasible on-chip integration into devices. Here, we report optically detected magnetic resonance (ODMR) from previously identified carbon-related defects in 2d hexagonal boron nitride (hBN). We show that single-defect ODMR contrast can be as strong as 6% and displays a magnetic-field dependence with both positive or negative sign per defect. This bipolarity can shed light into low contrast reported recently for ensemble ODMR measurements for these defects. Further, the ODMR lineshape comprises a doublet resonance, suggesting either low zero-field splitting or hyperfine coupling. Our results offer a promising route towards realising a room-temperature spin-photon quantum interface in hexagonal boron nitride.

description: The generation of the fermion mass hierarchy in the standard model of particle physics is a long-standing puzzle. The recent discoveries from neutrino physics suggests that the mixing in the lepton sector is large compared to the quark mixings. To understand this asymmetry between the quark and lepton mixings is an important aim for particle physics. In this regard, two promising approaches from the theoretical side are grand unified theories and family symmetries. In this note we try to understand certain general features of grand unified theories with Abelian family symmetries by taking the simplest SU(5) grand unified theory as a prototype. We construct an SU(5) toy model with $U(1)_F \otimes Z'_2\otimes Z''_2 \otimes Z'''_2$ family symmetry that, in a natural way, duplicates the observed mass hierarchy and mixing matrices to lowest approximation. The system for generating the mass hierarchy is through a Froggatt-Nielsen type mechanism. One idea that we use in the model is that the quark and charged lepton sectors are hierarchical with small mixing angles while the light neutrino sector is democratic with larger mixing angles. We also discuss some of the difficulties in incorporating finer details into the model without making further assumptions or adding a large scalar sector.

L’umanesimo di Aristotele fra politica, conoscenza e educazione

description: According to the author of this study, the nature of Aristotle’s work is, at the same time, humanistic and anthropocentric, unlike Plato’s work, which is hu- manistic and theocentric. The author arrives at this conclusion through exami- nation of the philosopher’s pedagogical ideas: the definition of the purposes and means of education is related to the quality of the responses on the organisation of human societies, on the problem of the common good, and on the nature of man both as a rational being and with reference to his place in the natural world.

description: Originally described from a sample collected in the Pamir Mountains at the end of the nineteenth century, Cyclotella lacunarum Hustedt is a centric diatom species that is not-well defined and seldom reported in the scientific literature. Our investigations revealed that the type locality of this taxon, now referred to as Lindavia lacunarum (Hustedt) Nakov et al., is actually in western China and not in Tajikistan, as wrongly assumed previously. Light microscope (LM) and scanning electron microscope (SEM) observations of the type material and of modern material collected at the type locality allowed us to emend the description of this species. Its most remarkable character is that it possesses central fultoportulae with only two satellite pores instead of three as generally reported for similar species of Lindavia. Lindavia lacunarum was then compared to two similar populations of Lindavia collected from high elevation lakes in Tajikistan and Nepal. These two populations were originally identified as Cyclotella/Lindavia lacunarum and represent the only reported occurrences of this taxon outside its type locality. The population from Tajikistan differs from L. lacunarum by having cells of smaller size, with an almost flat valve face and has been described as a new variety Lindavia lacunarum var. karakulensis var. nov. The Nepalese population is more clearly differentiated from L. lacunarum by having a different type of colliculate pattern in the central area and significantly lower density of central fultoportulae and is therefore described as a new species, Lindavia nepalensis sp. nov.
