description: We present a combined analysis of XMM-Newton, Chandra and Rosat observations of the isolated neutron star RXJ0720.4-3125, spanning a total period of \sim 7 years. We develop a maximum likelihood periodogramme for our analysis based on the ΔC-statistic and the maximum likelihood method, which are appropriate for the treatment of sparse event lists. Our results have been checked "a posteriori" by folding a further BeppoSAX dataset with the period predicted at the time of that observation: the phase is found to be consistent. The study of the spin history and the measure of the spin-down rate is of extreme importance in discriminating between the possible mechanisms suggested for the nature of the X-ray emission. The value of \dot P, here measured for the first time, is \approx 10^{-14} s/s. This value can not be explained in terms of torque from a fossil disk. When interpreted in terms of dipolar losses, it gives a magnetic field of B \approx 10^{13} G, making also implausible that the source is accreting from the underdense surroundings. On the other hand, we also find unlikely that the field decayed from a much larger value (B\approx 10^{15} G, as expected for a magnetar powered by dissipation of a superstrong field) since this scenario predicts a source age of \approx 10^4 yrs, too young to match the observed X-ray luminosity. The observed properties are more compatible with a scenario in which the source is \approx 10^6 yrs old, and its magnetic field has not changed substantially over the lifetime.

description: The recently detected polarization of the cosmic microwave background (CMB) holds the potential for revealing the physics of inflation and gravitationally mapping the large-scale structure of the universe, if so called B-mode signals below 10^{-7}, or tenths of a uK, can be reliably detected. We provide a language for describing systematic effects which distort the observed CMB temperature and polarization fields and so contaminate the B-modes. We identify 7 types of effects, described by 11 distortion fields, and show their association with known instrumental systematics such as common mode and differential gain fluctuations, line cross-coupling, pointing errors, and differential polarized beam effects. Because of aliasing from the small-scale structure in the CMB, even uncorrelated fluctuations in these effects can affect the large-scale B modes relevant to gravitational waves. Many of these problems are greatly reduced by having an instrumental beam that resolves the primary anisotropies (FWHM << 10'). To reach the ultimate goal of an inflationary energy scale of 3 \times 10^{15} GeV, polarization distortion fluctuations must be controlled at the 10^{-2}-10^{-3} level and temperature leakage to the 10^{-4}-10^{-3} level depending on effect. For example pointing errors must be controlled to 1.5'' rms for arcminute scale beams or a percent of the Gaussian beam width for larger beams; low spatial frequency differential gain fluctuations or line cross-coupling must be eliminated at the level of 10^{-4} rms.

description: In the last decade, virtual reality technology has become widely available to the public and is now used for a variety of applications in industries such as education, medicine and entertainment. One of the most important problems however, is virtual reality sickness which most users will experience. It is similar to similar to motion sickness, and thought to be caused by a mismatch of sensory signals that occur when the virtual experience does not match the real world. This thesis presents a mixed methods research project, that was undertaken using the Design Science methodology. A literature review was completed that defined what virtual reality sickness is, factors that are known to influence it and ways that these factors are being addressed in modern virtual reality technology. A comparison of migraine triggers against these factors was conducted, which showed many similarities between the two conditions, and provided a list of potential sickness factors for the research project to investigate. A series of experiments were run to investigate these factors, using a HTC Vive as the virtual reality headset, and a custom built Unity application to provide participants with tasks to complete. It required navigating a large virtual environment, interacting with a cockpit control system and completing a list of tasks within that space.

description: Using the Haystack Observatory 37-m radio telescope we have undertaken a search for emission in the 2(0)-3(1)E rotational transition of methanol in its first torsionally excited state (v_t=1) at 44.9 GHz. We examined seven galactic sources -- six strong emitters of Class II methanol maser lines and Orion KL, the only source where this line had been previously detected. We confirm (at a level of 5σ) the previous detection and report two new detections -- a reliable (9σ) detection in W3(OH) and a marginal (3.5σ) detection in NGC 6334F. Upper limits for other sources are presented. Although we did not see obvious signatures of maser amplification in this transition in any source, arguments in favor of weak masing in W3(OH) are presented.

description: We show in a model-independent way that the inhomogeneous cosmological class II Stephani model fulfills both the the cosmological holographic principle, and that the entropy is increasing with time. By this we mean the result does not depend on any assumption on the time evolution of the scale factor, or on the matter content of the Universe, we also do not need to use the numerical values of the cosmological parameters, which are inferred in the framework of the usual homogeneous Friedmann model. Therefore our analysis is not affected by the tension of the current estimates of the Hubble parameter, and does not rely on any model-dependent assumption of the entropy amount at the present epoch. Our analysis allows us to set an upper limit for the inhomogeneity parameter of the model, an upper bound for the size that this type of universe can reach during the time evolution, a lower bound for the entropy abundance, and an estimate of the present day value of the deceleration parameter.

description: The redshifted 21 cm line is an emerging tool in cosmology, in principle permitting three-dimensional surveys of our Universe that reach unprecedentedly large volumes, previously inaccessible length scales, and hitherto unexplored epochs of our cosmic timeline. Large radio telescopes have been constructed for this purpose, and in recent years there has been considerable progress in transforming 21 cm cosmology from a field of considerable theoretical promise to one of observational reality. Increasingly, practitioners in the field are coming to the realization that the success of observational 21cm cosmology will hinge on software algorithms and analysis pipelines just as much as it does on careful hardware design and telescope construction. This review provides a pedagogical introduction to state-of-the-art ideas in 21 cm data analysis, covering a wide variety of steps in a typical analysis pipeline, from calibration to foreground subtraction to mapmaking to power spectrum estimation to parameter estimation.

description: This dissertation titled 'A critical ethnography of an online file sharing community: an actor-network theory perspective of controversies in the digital music world' aims to provide an understanding of file sharing activities, and the technologies and systems that support these activities, while also considering the influencing role that the power structures of the music recording industry have. In doing so, it is possible to find out more about the individuals who are part of this subculture, and their motivations for file sharing. Through exploring the roles, rules, rituals, norms, values, ideologies, and language in file sharing, this dissertation gives detailed insight into how distribution and social structures in the music recording industry are changing, and how these changes impact on the way people access (search and download) and use (listen and share) music. These activities make up an online music experience, which can be thought of in contrast to the music experience (access and use) before the Internet, which centred primarily on physical artifacts (CD’s, cassettes, albums) and other sources of music radio, concerts). To fulfil this research aim, this dissertation answers the research question: 'How do information systems support unauthorised file sharing activities within an underground online community?'. To understand file sharing activities in an underground online community, it is important to situate them within a wider social, political, legal and historical context. Within this wider context, this dissertation demonstrates the controversies that have emerged with the growth of the Internet as a distribution mechanism for music...

description: We report new millimeter observations of the circumstellar material surrounding the Herbig Ae A0.5 star HD 34282 performed with the IRAM array in CO J=2-1 and in continuum at 1.3 mm. These observations have revealed the existence of a large Keplerian disk around the star. We have analysed simultaneously the line and continuum emissions to derive the physical properties of both the gas and the dust. The analysis of our observations also shows that the Hipparcos distance to the star is somewhat underestimated ; the actual distance is probably about 400 pc. With this distance the disk around HD 34282 appears more massive and somewhat hotter than the observed disks around less massive T Tauri stars, but shares the general behaviour of passive disks.

description: Phosphorene, a single layer of black phosphorus, is a direct-band gap two-dimensional semiconductor with promising charge and spin transport properties. The electronic band structure of phosphorene is strongly affected by the structural anisotropy of the underlying crystal lattice. We describe the relevant conduction and valence bands close to the $Γ$ point by four- and six-band (with spin) $k \cdot p$ models, including the previously overlooked interband spin-orbit coupling which is essential for studying anisotropic crystals. All the $k \cdot p$ parameters are obtained by a robust fit to {\it ab initio} data, by taking into account the nominal band structure and the $k$-dependence of the effective mass close to $Γ$-point. The inclusion of interband spin-orbit coupling allows us to determine dipole transitions along both armchair and zigzag directions. The interband coupling is also key to determine the effective g-factors and Zeeman splittings of the Landau levels. We predict the electron and hole g-factor correction of $\approx 0.03$ due to the intrinsic contributions in phosphorene, which lies within the existing range of experimental data. Furthermore, we investigate excitonic effects using the $k \cdot p$ models and find exciton binding energy (0.81 eV) and exciton diameters consistent with experiments and {\it ab initio} based calculations. The proposed $k \cdot p$ Hamiltonians should be useful for investigating magnetic, spin, transport, optical properties and many-body effects in phosphorene.

description: We consider the strangeness-changing decays of hyperons into another baryon and missing energy which is carried away by a pair of invisible spinless bosons. Pursuing a model-independent approach and taking into account constraints from the kaon sector, we find that these hyperon modes can have large rates, especially if the bosons have parity-odd effective couplings to light quarks. In that case the rates could attain values which are well within the expected reach of the currently running BESIII experiment. Since the branching fractions of hyperon decays with missing energy are tiny in the standard model, observing them at ongoing or upcoming facilities would likely be indicative of new physics. In addition, we show that the kaon restrictions may be weakened or absent if the bosons have nonnegligible mass. Specifically, if the bosons interact with the quarks solely via an axial-vector current, in the mass region from about 115 to 175 MeV the constraints from rare kaon decays no longer apply and a couple of the hyperon modes become the only direct probes of such interactions. We also make comparisons with the previously explored new-physics scenario where the invisible particles are spin-1/2 fermions.

description: The SoHO spacecraft made astrophysicists achieve a major breakthrough in the knowledge of the Sun. In helioseismology, both GOLF and MDI experiments aboard SoHO greatly improve the accuracy of seismic data. More specifically, the detection of an enhanced number of low degree low order modes improves the accuracy on the sound speed and density profiles in the solar core. After a description of these profiles, we build solar seismic models. Different models are considered and enable us to derive precise emitted neutrino fluxes. These ones are validated by the seismic data and are in agreement with the recent detected neutrinos, assuming 3 neutrino flavors. The seismic models are also used to put limits on large scale magnetic fields in the solar interior. This analysis puts some upper bounds of about 3x10^7 G in the radiative zone. Such a field could slightly improve the emitted neutrino flux, which remains in agreement with the Sudbury Neutrino Observatory result of 2001. From the models we deduce gravity mode predictions, and the electron and neutron radial densities that are useful to calculate the neutrino oscillations. We also begin to discuss how the external magnetic field may influence such quantities.

description: Body sizes in endothermic species tend to increase as temperature decreases in accordance with Bergmann’s rule. However, why do some species support Bergmann’s clines while others reverse it? This question should be solved by considering the relative contributions of mean age and growth rate on adult ectotherm body size. Here we studied altitudinal variation in mean body size, age, and growth rate in Rana kukunoris through 16 sites at different altitudes in the eastern Tibetan Plateau. Our results revealed that mean body size decreased as altitude increased in each sex, which fails to obey Bergmann’s rule, but supports the converse Bergmann’s rule. Frogs at lower altitudes tended to grow faster than individuals of the same species at higher altitudes. Conversely, age of adults did not significantly increase as altitude increased. Therefore, we suggest that lower growth rate limits the mean individual body size at the altitudes, explaining why this species follows the converse Bergmann’s rule. The effect of age cannot be ignored because decreasing body length with increasing altitudes is not significant when removing the effect of age.

Zeasampa

description: Zeasampa Nomura and Leschen, new genus  (Figs. 18B, 21, 22)
 Type species: Zeasampa nunni Nomura and Leschen, new species.
 Diagnosis. Body relatively small (2.14–2.38 mm), with dorsal surfaces of the head, pronotum, and elytra smooth (Fig. 18B). Head transverse, wider than prothorax and broad, widest just before antennal base, strongly flattened anteriad, weakly narrowed posteriad, vertex almost flat, with pair of dorsal tentorial pits; posterior constriction not notched, with lateral fovea present; postgenae moderate, venter not bearded (Fig. 21B). Eyes very small, not visible in dorsal view (Fig. 18B). Antennae long and slender, each reaching elytral base, with insertions hidden in dorsal view; antennomere I very large, asymmetrically thickened in male, about as long as antennomeres II–V; antennal club formed by VII–XI in male; antennal tubercles absent. Maxillary palpi short, elongate; palpomere IV largest, subcylindrical. Pronotum narrower than head, rounded laterally, with pair of small lateral foveae at about basal 1/3 (Fig. 21A). Metaventrite very large, weakly convex (Fig. 21E). Elytra very large, about as long as head + pronotum in dorsal view, slightly broadened posteriad, each elytron gently flattened dorsally, with complete adsutural sulcus, without basal foveae (Fig. 21F). Prosternum lacking lateral and median longitudinal carinae. Ventral foveae simple and reduced, those present as follows: gula (head); lateral procoxal (prosternum). Legs long, slender, smooth on dorsal surface; 1 tarsal claw present.
Abdomen about as long as and slightly narrower than elytra, sides subparallel; abdominal segments II–VII subequal in length, each transverse, IV–VI each with pair of narrow, subparallelsided paratergites (Fig. 21G). Male genitalia weakly sclerotized, median lobe asymmetrical (Fig. 22D, E).
 Remarks. Zeasampa may be allied to Neosampa in having an elongate body, a transverse and anteriorly flattened head, the prosternum lacking lateral carinae, and a subparallel-sided abdomen. However, Zeasampa is remarkably different by the smooth and broad head, pronotum and elytra smooth on dorsal surface, the very thick head, asymmetrically thickened antennomere I, and elytra completely lacking basal foveae.
 Etymology. This new generic name is formed by the prefix “ Zea -” combined with the latter part of the related genus Neosampa.

description: Magnetic flux trapped during the cooldown of superconducting radio-frequency cavities through the transition temperature due to incomplete Meissner state is known to be a significant source of radio-frequency losses. The sensitivity of flux trapping depends on the distribution and the type of defects and impurities which pin vortices, as well as the cooldown dynamics when the cavity transitions from a normal to superconducting state. Here we present the results of measurements of the flux trapping sensitivity on 1.3 GHz elliptical cavities made from large-grain niobium with different purity for different cooldown dynamics and surface treatments. The results show that lower purity material results in a higher fraction of trapped flux and that the trapped flux sensitivity parameter $S$ is significantly affected by surface treatments but without much change in the mean free path $l$. We discuss our results within an overview of published data on the dependencies of $S(l,f)$ on $l$ and frequency $f$ using theoretical models of rf losses of elastic vortex lines driven by weak rf currents in the cases of sparse strong pinning defects and collective pinning by many weak defects. Our analysis shows how multiscale pinning mechanisms in cavities can result in a maximum in $S(l)$ similar to that observed by the FNAL and Cornell groups and how pinning characteristics can be extracted from the experimental data. Here the main contribution to $S$ come from weak pinning regions at the cavity surface, where dissipative oscillations along trapped vortices perpendicular to the surface propagate into the bulk well beyond the layer of rf screening current.

description: The proton-induced $α$ knockout reaction has been utilized for decades to investigate the $α$ cluster states of nuclei, of the ground state in particular. However, even in recent years, it is reported that the deduced $α$ spectroscopic factors from $α$ knockout experiments and reaction analyses with a phenomenological $α$ cluster wave function diverge depending on the kinematical condition of the reaction. In the present study we examine the theoretical description of the $^{20}$Ne($p$,$pα$)$^{16}$O cross section based on the antisymmetrized molecular dynamics and the distorted wave impulse approximation by comparing with existing experimental data. We also investigate the correspondence between the $α$ cluster wave function and the $α$ knockout cross section. The existing $^{20}$Ne($p$,$pα$)$^{16}$O data at 101.5 MeV is well reproduced by the present framework. Due to the peripherality of the reaction, the surface region of the cluster wave function is selectively reflected to the knockout cross section. A quantitatively reliable $α$ cluster wave function, $p$-$α$ cross section, and distorting potentials between scattering particles, $α$-$^{16}$O in particular, are crucial for the quantitative description of the ($p$,$pα$) cross section. Due to the peripherality of the reaction, the ($p$,$pα$) cross section is a good probe for the surface $α$ amplitude.

description: Malnutrition is a significant problem in the hospital setting, contributing to adverse outcomes for patients, such as increased risks of complications and death, and also for the health care system, through increased hospital costs and length of stay. Malnutrition is also an identified risk factor for pressure injury. Nutritional intervention for pressure injury prevention is therefore an important consideration in the hospital setting, to avoid substantial costs and patient burden associated with pressure injury. Adopting a suitable framework for intervention planning in the clinical setting may improve the likelihood of its success. Public health nutrition, whilst having a different focus to clinical dietetics, may give new insight into nutrition intervention planning in the hospital setting. Public health nutrition focuses on the prevention of nutrition related health conditions by addressing upstream determinants of the problem at a broader population level. In contrast, clinical dietetics traditionally focuses on the treatment of established nutrition related conditions by providing individualised dietetic care. However, there is an increasing focus on preventative care in hospitals, particularly in relation to pressure injury prevention. Given a considerable proportion of pressure injuries in hospitals may be attributable to malnutrition, adopting a public health nutrition framework for intervention planning may be suitable in the clinical setting. That is, applying a nutrition intervention at a broader hospital population level, to address upstream determinants of pressure injury (i.e. malnutrition) in order for its prevention. This thesis therefore explores the utility of a public health nutrition framework, the bi-cycle model (Hughes and Margetts 2011), for intervention planning and delivery in the clinical setting.

description: The variations of short-range correlations (SRC) across nuclei can be quantified in an approximately model-independent fashion in terms of the so-called SRC scaling factors. We provide predictions for the SRC scaling factors for both bound protons and bound neutrons across the nuclear periodic table and determine the contribution of the different nucleon pair combinations to this quantity. Thereby we employ the low-order correlation operator approximation (LCA) to compute the SRC contribution to the single-nucleon momentum distribution. We do this for a sample of fifteen nuclei from He to Pb thereby gaining access to the evolution of the SRC scaling factor with the nuclear mass and the neutron-to-proton ratio. For the studied sample of fifteen nuclei, the total SRC scaling factor is in the range 4.05-5.14. The computed SRC scaling factors in the LCA are in line with those of ab-initio calculations and with measured quantities from SRC-sensitive inclusive electron-scattering data. In asymmetric nuclei there are sizeable differences between the SRC scaling factors for protons and neutrons. It is suggested that this phenomenon may impact the variations of the magnitude of the European muon collaboration (EMC) effect across nuclei. Our results corroborate the finding that SRC physics can be qualitatively understood by universal principles that build on local modifications of mean-field wave functions of nucleon pairs.

description: In order to recognize environmental effects on the evolution of dwarf galaxies in clusters of galaxies, it is first necessary to quantify the properties of objects which have evolved in relative isolation. With oxygen abundance as the gauge of metallicity, two key diagnostics of the evolution of dwarf irregular galaxies in the field are re-examined: the metallicity-luminosity relationship and the metallicity-gas fraction relationship. Gas fractions are evaluated from the masses of luminous components only, i.e., constituents of the nucleogenetic pool. Results from new optical spectroscopy obtained for H II regions in five dwarf irregular galaxies in the Local Volume are incorporated into a new analysis of field dwarfs with [O III]4363 detections and good distances. The updated fit to the metallicity-luminosity relationship is consistent with results reported in the literature. The fit to the metallicity-gas fraction relation shows an excellent correlation consistent with expectations of the simple "closed box" model of chemical evolution. The simplest explanation consistent with the data is that flow rates are zero, although the observations allow for the possibility of modest flows. The derived oxygen yield is one-quarter of the value for the solar neighbourhood.

Hyperholomorpic connections on coherent sheaves and stability

description: Let $M$ be a hyperkaehler manifold, and $F$ a torsion-free and reflexive coherent sheaf on $M$. Assume that $F$ (outside of its singularities) admits a connection with a curvature which is invariant under the standard SU(2)-action on 2-forms. If the curvature is square-integrable, then $F$ is stable and its singularities are hyperkaehler subvarieties in $M$. Such sheaves (called hyperholomorphic sheaves) are well understood. In the present paper, we study sheaves admitting a connection with SU(2)-invariant curvature which is not necessarily square-integrable. This situation arises often, for instance, when one deals with higher direct images of holomorphic bundles. We show that such sheaves are stable.

description: Let G be a torsion free discrete group and let \bar{Q} denote the field of algebraic numbers in C. We prove that \bar{Q}[G] fulfills the Atiyah conjecture if G lies in a certain class of groups D, which contains in particular all groups which are residually torsion free elementary amenable or which are residually free. This result implies that there are no non-trivial zero-divisors in C[G]. The statement relies on new approximation results for L2-Betti numbers over \bar{Q}[G], which are the core of the work done in this paper. Another set of results in the paper is concerned with certain number theoretic properties of eigenvalues for the combinatorial Laplacian on L2-cochains on any normal covering space of a finite CW complex. We establish the absence of eigenvalues that are transcendental numbers, whenever the covering transformation group is either amenable or in the Linnell class \mathcal{C}. We also establish the absence of eigenvalues that are Liouville transcendental numbers whenever the covering transformation group is either residually finite or more generally in a certain large bootstrap class \mathcal{G}. Please take the errata to Schick: "L2-determinant class and approximation of L2-Betti numbers" into account, which are added at the end of the file, rectifying some unproved statements about "amenable extension". As a consequence, throughout, amenable extensions should be extensions with normal subgroups.

description: Body sizes in endothermic species tend to increase as temperature decreases in accordance with Bergmann’s rule. However, why do some species support Bergmann’s clines while others reverse it? This question should be solved by considering the relative contributions of mean age and growth rate on adult ectotherm body size. Here we studied altitudinal variation in mean body size, age, and growth rate in Rana kukunoris through 16 sites at different altitudes in the eastern Tibetan Plateau. Our results revealed that mean body size decreased as altitude increased in each sex, which fails to obey Bergmann’s rule, but supports the converse Bergmann’s rule. Frogs at lower altitudes tended to grow faster than individuals of the same species at higher altitudes. Conversely, age of adults did not significantly increase as altitude increased. Therefore, we suggest that lower growth rate limits the mean individual body size at the altitudes, explaining why this species follows the converse Bergmann’s rule. The effect of age cannot be ignored because decreasing body length with increasing altitudes is not significant when removing the effect of age.

description: Selective two-electron oxygen reduction reaction (ORR) offers a promising route for hydrogen peroxide synthesis, and defective sp2 carbon-based materials are attractive, low-cost electrocatalysts for this process. However, due to a wide range of possible defect structures formed during material synthesis, identification and fabrication of precise active sites remain a challenge. Here, we report a graphene edgebased electrocatalyst for two-electron ORR - nanowire-templated three-dimensional fuzzy graphene (NT3DFG). NT-3DFG exhibits excellent efficiency (onset potential of 0.79 $\pm$ 0.01 V versus RHE), selectivity (93 $\pm$ 3 % H2O2), and tunable ORR activity as a function of graphene edge site density. Using spectroscopic surface characterization and density functional theory calculations, we find that NT-3DFG edge sites are readily functionalized by carbonyl (C=O) and hydroxyl (C-OH) groups under alkaline ORR conditions. Our calculations indicate that multiple site configurations at both armchair and zigzag edges may achieve a local coordination environment that allows selective, two-electron ORR. We derive a general geometric descriptor based on the local coordination environment that provides activity predictions of graphene surface sites within ~0.1 V of computed values. Herein we combine synthesis, spectroscopy, and simulations to improve active site characterization and accelerate carbon-based electrocatalyst discovery.
