description: Rubrafasciculus Ekins, Erpenbeck & Hooper gen. nov.
urn:lsid:zoobank.org:act: 628D9059-A8D3-4EED-893B-FEDBD4A8F3DB
Definition. Armoured with a sparse skeleton, primary fibres are sparse and fasciculated, laminated and cored with foreign debris. Debris is often a bark on the outside of the primary fibres. Secondary fibres are laminated and often cored, and form an irregular, netlike branching network. The whole sponge has a heavy collagenous matrix.
Diagnosis. Cherry red coloured, lobate, massive, fistular, sometimes semi-buried with only the fistules showing above the sand. The sponge has apically located oscules and a conulose surface showing a regular geometric pattern. The skeleton is irregular and supported by the heavy collagenous matrix. The sponges are sparely armoured and heavily associated with sand. The primary fibres are sparse and fasciculated, laminated and cored with foreign debris. The sand sometimes forms a bark on the outside of the primary fibres. Secondary fibres are laminated and often cored, and form an irregular, netlike branching network. The primary and secondary fibres are often of a similar size, but secondary fibres may be up to half the diameter of the primary fibres.
Remarks. Rubrafasciculus gen. nov. differs from Skolosachlys gen. nov. by lacking the coring of secondary fibres and lacking the partial striated armouring. It has armouring which distinguishes it from Fascaplysinopsis as well as by lacking the axial granular thread in the secondary fibres of Fascaplysinopsis. Rubrafasciculus gen. nov. differs from all other members of Thorectinae that have armouring i.e. Aplysinopsis, Thorecta and Thorectandra by the fasciculation of primary fibres. All other genera in Thorectinae lack armouring. Petrosaspongia, which has superficial armouring, also lacks the fasciculation of primary fibres (Table 1). Rubrafasciculus gen. nov. is identifiable in the field by the red colouration and the geometric pattern on the surface.
Etymology. Rubra, L. red, fasciculus L. dim. of fascis ‘bundle’
Type species: Rubrafasciculus cerasus sp. nov. here designated.

description: We investigate the effect on biomembrane mechanical properties due to the presence an external potential for a non-conductive non-compressible membrane surrounded by different electrolytes. By solving the Debye-Huckel and Laplace equations for the electrostatic potential and using the relevant stress-tensor we find: in (1.) the small screening length limit, where the Debye screening length is smaller than the distance between the electrodes, the screening certifies that all electrostatic interactions are short-range and the major effect of the applied potential is to decrease the membrane tension and increase the bending rigidity; explicit expressions for electrostatic contribution to the tension and bending rigidity are derived as a function of the applied potential, the Debye screening lengths and the dielectric constants of the membrane and the solvents. For sufficiently large voltages the negative contribution to the tension is expected to cause a membrane stretching instability. For (2.) the dielectric limit, i.e. no salt (and small wavevectors compared to the distance between the electrodes), when the dielectric constant on the two sides are different the applied potential induces an effective (unscreened) membrane charge density, whose long-range interaction is expected to lead to a membrane undulation instability.

description: The transformation of cortisol into prednisolone in cattle faeces was demonstrated and provided by literature, given the structural similarity of prednisolone with cortisol. In this study, we evaluated a possible neo-formation of prednisolone, as results of a faecal or environmental contamination. A saponine, α-solanine, and a sapogenin, diosgenin, were selected as possible precursors. A simple method without extraction was applied. The analyses were performed by HPLC–MSn to evaluate the possible transformations. The results showed that prednisolone was detected in the faecal suspension spiked with diosgenin at t= 8h, while cortisol was also detected at t = 24h in the sample of faeces spiked with α-solanine. In the feed and in the control samples, no transformations were observed.

description: In this paper we show that dark matter in the form of dense matter/antimatter nuggets could provide a natural and unified explanation for several distinct bands of diffuse radiation from the core of the Galaxy spanning over 12 orders of magnitude in frequency. We fix all of the phenomenological properties of this model by matching to x-ray observations in the keV band, and then calculate the unambiguously predicted thermal emission in the microwave band, at frequencies smaller by 10 orders of magnitude. Remarkably, the intensity and spectrum of the emitted thermal radiation are consistent with--and could entirely explain--the so-called "WMAP haze": a diffuse microwave excess observed from the core of our Galaxy by the Wilkinson Microwave Anisotropy Probe (WMAP). This provides another strong constraint of our proposal, and a remarkable nontrivial validation. If correct, our proposal identifies the nature of the dark matter, explains baryogenesis, and provides a means to directly probe the matter distribution in our Galaxy by analyzing several different types of diffuse emissions.

Fluctuation diamagnetism around the superconducting transition in a cuprate crystal with a reduced Meissner fraction

description: The magnetization around the superconducting transition was measured in a Tl$_{0.5}$Pb$_{0.5}$Sr$_2$CaCu$_2$O$_7$ crystal affected by a considerable reduction ($\sim$55%) of its effective superconducting volume fraction but still with a relatively sharp low-field Meissner transition, a behaviour that may be attributed to the presence of structural inhomogeneities. By taking into account these inhomogeneities just through the Meissner fraction, the observed diamagnetism may still be explained, consistently above and below the superconducting transition, in terms of the conventional Ginzburg-Landau approach with fluctuations of Cooper pairs and vortices.

Retrofitting suburbs : case studies of the evolution of the urban fringe
Creators: name: Mortensen, Michael S.
Publisher: name: University of British Columbia
Year: 2009

description: As the first post-war suburbs turn fifty, there will be a window of opportunity to retrofit these places to meet contemporary housing and community needs. Field studies conducted in five postwar-era subdivisions in Richmond BC reveal that a cycle of housing demolition and redevelopment began in the late 1980s. Unfortunately, dated zoning bylaws continue to exclude forms of development that depart from the singlefamily template of the 1950s. There are, however, examples of better redevelopment practices within the older urban fabric. Case studies in Vancouver's first-ring of streetcar suburbs reveal that a wide range of housing redevelopment has been enabled by a participatory process of discretionary rezoning over the past twenty-five years. The concrete examples of urban form, land-use policies and planning processes offered by the Vancouver experience can be applied in the redevelopment of postwar suburbs. Recent planning in Delta BC suggests that this approach can be used with success.

description: Parallaxes measured by the Gaia mission have huge significance for astronomy, but parallaxes in Gaia DR2 are known to have systematic errors that depend on the source position and other quantities. We use the abundant information in faint Milky Way stars, along with the GOG simulation of the Gaia catalog, to probe the spatial dependence of Gaia DR2 parallax systematic errors in an empirical way. The parallax signal, concentrated in thick disk turnoff stars with magnitude G ~ 17, is sufficient to construct maps of the parallax systematic error over the majority of the sky. These maps show a locally regular "waffle pattern" on ~1 degree scales following Gaia scan directions, stronger linear "scar" features, and coherent variations on larger scales. The parallax bias maps also retain traces of astrophysical effects such as dust clouds. The waffle pattern, known from earlier maps of the Magellanic Clouds, extends over the entire sky; its local rms amplitude averages 15 microarcsec and varies by about a factor of two. The strength of this pattern increases by a factor ~6 from magnitude G = 13 to G = 20. Correlations with parallaxes of quasars and of stars with independent distance estimates support our bias estimates. Using similar methods, we map systematic errors in the proper motion and examine the relationship with the parallax systematics. We provide a code package to access and query our bias maps. Similar tests on the general stellar population should be useful in quantifying systematic errors in future Gaia releases.

A priori Wannier functions from modified Hartree-Fock and Kohn-Sham equations

Year: 2006
Subjects: subject: Other Condensed Matter (cond-mat.other)

description: The Hartree-Fock equations are modified to directly yield Wannier functions following a proposal of Shukla et al. [Chem. Phys. Lett. 262, 213-218 (1996)]. This approach circumvents the a posteriori application of the Wannier transformation to Bloch functions. I give a novel and rigorous derivation of the relevant equations by introducing an orthogonalizing potential to ensure the orthogonality among the resulting functions. The properties of these, so-called a priori Wannier functions, are analyzed and the relation of the modified Hartree-Fock equations to the conventional, Bloch-function-based equations is elucidated. It is pointed out that the modified equations offer a different route to maximally localized Wannier functions. Their computational solution is found to involve an effort that is comparable to the effort for the solution of the conventional equations. Above all, I show how a priori Wannier functions can be obtained by a modification of the Kohn-Sham equations of density-functional theory.

description: In a previous paper [Phys. Rev. D 68, 034017 (2003)], we investigated the inclusive production of prompt J/psi mesons in polarized hadron-hadron, photon-hadron, and photon-photon collisions in the factorization formalism of nonrelativistic quantum chromodynamics providing compact analytic results for the double longitudinal-spin asymmetry A_{LL}. For convenience, we adopted a simplified expression for the tensor product of the gluon polarization four-vector with its charge conjugate, at the expense of allowing for ghost and anti-ghosts to appear as external particles. While such ghost contributions cancel in the cross section asymmetry A_{LL} and thus were not listed in our previous paper, they do contribute to the absolute cross sections. For completeness and the reader's convenience, they are provided in this addendum.

description: Cytokinesis is the final stage of cell division where major rearrangements of the cytoskeleton occur that result in the formation and constriction of a contractile ring at the equator of the cell. The GTPase Rho is essential for cytokinesis and it is the role of the Rho GTPase Exchange Factor (GEF) Pbl to stimulate the accumulation of an equatorial band of active Rho. Accumulation of Pbl at the midzone requires an interaction with the GTPase Activating Protein (GAP) Tum, which forms a heterotetrameric complex with the microtubule motor protein Pavarotti (Pav). It is the motor activity of Pav that localizes Pbl and Tum to the equator where they activate downstream cytokinetic effectors and thereby induce contractile ring formation and constriction. However, the mechanism/s regulate the Pbl-Tum interaction during cytokinesis are unknown. This thesis describes two strategies that probe the Pbl-Tum interaction using a structure-function analysis. The first strategy details attempts to over-express and purify Pbl and Tum in an effort to obtain enough pure protein with which to perform structural studies. The second strategy compares the effect of wild-type and mutant transgenes to identify phosphorylation events that mediate the Pbl-Tum interaction. Through this work I identified a previously uncharacterized phosphorylation event in Tum that is required to bind and localize Pbl to the equator in vivo in Drosophila.

description: Within the scope of extended matter research, we present new spectral analysis results of an active binary system AR Lac. The low and high resolution spectra of this system were taken during the period 2013-2016. The evaluation of low dispersion spectra together with the B, V, Rc, Ic and WISE photometric data showed that AR Lac has an excess radiation in W2 band. In addition, the spectral energy distribution and the minima depth ratios of the light curves of this active binary system were studied to examine the flux contributions of the components of the system depending on wavelengths and on orbital phase. Furthermore, high resolution spectral analysis showed evidence of prominence-like structures and a possible extended matter around the cooler component of AR Lac binary system.

description: Ever since Ernest Rutherford scattered alpha-particles from gold foils(1), collision experiments have revealed insights into atoms, nuclei and elementary particles(2). In solids, many-body correlations lead to characteristic resonances(3)-called quasiparticles-such as excitons, dropletons(4), polarons and Cooper pairs. The structure and dynamics of quasiparticles are important because they define macroscopic phenomena such as Mott insulating states, spontaneous spin-and charge-order, and high-temperature superconductivity(5). However, the extremely short lifetimes of these entities(6) make practical implementations of a suitable collider challenging. Here we exploit lightwave-driven charge transport(7-24), the foundation of attosecond science(9-13), to explore ultrafast quasiparticle collisions directly in the time domain: a femtosecond optical pulse creates excitonic electron-hole pairs in the layered dichalcogenide tungsten diselenide while a strong terahertz field accelerates and collides the electrons with the holes. The underlying dynamics of the wave packets, including collision, pair annihilation, quantum interference and dephasing, are detected as light emission in high-order spectral sidebands(17-19) of the optical excitation. A full quantum theory explains our observations microscopically. This approach enables collision experiments with various complex quasiparticles and suggests a promising new way of generating sub-femtosecond pulses.
Plant growth promoting rhizobacteria (PGPR) for interior spruce (Picea engelmannii x P. glauca) seedlings
Creators: name: Shishido, Masahiro
Publisher: name: University of British Columbia
Year: 2009

description: The relationship between interior spruce (Picea engelmannii Parry x P. glauca (Moench) Voss) and plant growth promoting rhizobacteria (PGPR) was studied under controlled environments and in the field. Large, statistically significant biomass increases were detected in spruce seedlings after PGPR inoculation, but seedling growth responses were variable. Coadaptation involving host plants, PGPR and forest floor soils did not appear to explain such variability. Synergistic effects of PGPR and mycorrhizal fungi on seedling growth were detected, but growth promotion also occurred in the absence of mycorrhizae, which suggests that bacteria x mycorrbizae interactions were unrelated to seedling growth response variability. PGPR colonization of seedling tissues was assessed using immunofluorescent microscopy and dilution plate counts. When three Bacillus and three Pseudomonas strains were inoculated onto spruce seedling roots under gnotobiotic conditions, only Bacillus Pw2R and Pseudomonas Sm3RN were detected inside stem vascular tissues four months later. A field experiment was performed to evaluate differences in root colonization and seedling growth promotion between these endophytic and non-endophytic PGPR. Relative growth rates of spruce seedlings in the field suggested that once induced in the greenhouse, seedling growth promotion persisted under field conditions for at least four months. However, endophytic PGPR offered no apparent advantage over non-endophytes as growth promoters. Mechanistic studies of plant growth promotion in sterile microcosms suggested that strains L6-16R, Pw2R, S20R, Sm3RN and Sw5RN did not depend on the presence of other deleterious microorganisms to promote seedling growth, but that strain Ss2RN might. However, addition of sterilized forest soil extracts facilitated seedling growth promotion by most PGPR. These results suggest that abiotic soil compounds may act as precursor substrates for PGPR production of plant growth stimulating substances, possibly, but not restricted to, phytohormones. Patchy distribution of such precursors in soil could cause seedling growth variability in response to PGPR inoculation. Finally, PGPR were observed to change soil microbial community population sizes and carbon substrate utilization patterns. Seedlings buffered these effects in only one of two forest soils evaluated, indicating that the origin of the soil microbial community is important in determining microfloral responses to PGPR introduction.

description: The Discrete Element Method (DEM) is frequently used to model complex granular systems and to augment the knowledge that we obtain through theory, experimentation, and real-world observations. Numerical simulations are a particularly powerful tool for studying the regolith-covered surfaces of asteroids, comets, and small moons, where reduced-gravity environments produce ill-defined flow behaviors. In this work, we present a method for validating soft-sphere DEM codes for both terrestrial and small-body granular environments. The open-source code Chrono is modified and evaluated first with a series of simple two-body-collision tests, and then, with a set of piling and tumbler tests. In the piling tests, we vary the coefficient of rolling friction to calibrate the simulations against experiments with 1 mm glass beads. Then, we use the friction coefficient to model the flow of 1 mm glass beads in a rotating drum, using a drum configuration from a previous experimental study. We measure the dynamic angle of repose, the flowing layer thickness, and the flowing layer velocity for tests with different particle sizes, contact force models, coefficients of rolling friction, cohesion levels, drum rotation speeds and gravity levels. The tests show that the same flow patterns can be observed at Earth and reduced-gravity levels if the drum rotation speed and the gravity-level are set according to the dimensionless parameter known as the Froude number. Chrono is successfully validated against known flow behaviors at different gravity and cohesion levels, and will be used to study small-body regolith dynamics in future works.

description: Plants have represent a promising alternative for biopharmaceutical proteins (Ma et al., 2003; Rossi et al., 2014). Many plant based edible vaccines have been shown to be effective in inducing local immune responses (Rossi et al., 2013). Edible vaccines can activate both mucosal and systemic immunity, as they come in contact with the digestive tract lining. This dual effect would provide first-line defense against pathogens invading through the mucosa. The antigens are released in the intestines are taken up by M cells that are present over the Payer’s patches (in the ileum) and the gut associated lymphoid tissue (GALT). Edible vaccines represent an important worldwide goal for the prevention of the enteric diseases, also in livestock. In particular, the enteric infections are a significant clinical problem in pigs. Verocytotoxic Escherichia (E.) coli strains are responsible for serious enterotoxaemia that causes important economic losses in the pig industry. The production of a vaccine for oral administration of transgenic seeds could be a practical and efficient system to prevent the infection and to reduce the antibiotic use. This study was focused on tobacco plants, previously transformed by agroinfection for the seed-specific expression of antigenic proteins (F18 adhesive fimbriae and the B subunit of the Vt2e toxin) as model of edible vaccines against verocytotoxic E. coli strains. The dietary administration of transgenic tobacco seeds promotes a significant increase in the number of mucosal IgA-producing cells of the tunica propria in both small and large intestine in mice (Rossi et al., 2013). A protective effect of oral administration of transgenic tobacco seeds was also observed against verocytotoxic Escherichia coli infection in piglets (Rossi et al., 2014). The aim of this study was to assess the seed-expression stability, that is a important requirement in the vaccine production, of F 18 and Vt2e-B heterologous genes into the progeny of transformed tobacco plants.

description: Scanning diamond magnetometers based on the optically detected magnetic resonance of the nitrogen-vacancy centre offer very high sensitivity and non-invasive imaging capabilities when the stray fields emanating from ultrathin magnetic materials are sufficiently low (< 10 mT). Beyond this low-field regime, the optical signal quenches and a quantitative measurement is challenging. While the field-dependent NV photoluminescence can still provide qualitative information on magnetic morphology, this operation regime remains unexplored particularly for surface magnetisation larger than $\sim$ 3 mA. Here, we introduce a multi-angle reconstruction technique (MARe) that captures the full nanoscale domain morphology in all magnetic-field regimes leading to NV photoluminescence quench. To demonstrate this, we use [Ir/Co/Pt]$_{14}$ multilayer films with surface magnetisation an order of magnitude larger than previous reports. Our approach brings non-invasive nanoscale magnetic field imaging capability to the study of a wider pool of magnetic materials and phenomena.

description: We discuss the influence of periodic orbits on the dissociation of a model diatomic molecule driven by a strong bichromatic laser fields. Through the stability of periodic orbits we analyze the dissociation probability when parameters like the two amplitudes and the phase lag between the laser fields, are varied. We find that qualitative features of dissociation can be reproduced by considering a small set of short periodic orbits. The good agreement with direct simulations demonstrates the importance of bifurcations of short periodic orbits in the dissociation dynamics of diatomic molecules.

description: We investigate in detail two physical properties of the metric f(R) theory developed by Sobouti (2007). We first look for the possibility of producing gravitational waves that travel at the speed of light. We then check the possibility of producing extra bending in the lenses produced by the theory. We do this by using standard weak field approximations to the gravitational field equations that appear in Sobouti's theory. We show in this article that the metric theory of gravitation proposed by Sobouti (2007) predicts the existence of gravitational waves travelling at the speed of light in vacuum. In fact, this is proved in general terms for all metric theories of gravity which can be expressed as powers of Ricci's scalar. We also show that an extra additional lensing as compared to the one predicted by standard general relativity is produced. These two points are generally considered to be of crucial importance in the development of relativistic theories of gravity that could provide an alternative description to the dark matter paradigm.

description: We study the death and restoration of collective oscillations in networks of oscillators coupled through random-walk diffusion. Differently than the usual diffusion coupling used to model chemical reactions, here the equilibria of the uncoupled unit is not a solution of the coupled ensemble. Instead, the connectivity modifies both, the original unstable fixed point and the stable limit-cycle, making them node-dependent. Using numerical simulations in random networks we show that, in some cases, this diffusion induced heterogeneity stabilizes the initially unstable fixed point via a Hopf bifurcation. Further increasing the coupling strength the oscillations can be restored as well. Upon numerical analysis of the stability properties we conclude that this is a novel case of amplitude death. Finally we use a heterogeneous mean-field reduction of the system in order to proof the robustness of this phenomena upon increasing the system size.

description: The existence of long lived superheavy nuclei (SHN) is controlled mainly by spontaneous fission and $α$-decay processes. According to microscopic nuclear theory, spherical shell effects at Z=114, 120, 126 and N=184 provide the extra stability to such SHN to have long enough lifetime to be observed. To investigate whether the so-called "stability island" could really exist around the above Z, N values, the $α$-decay half lives along with the spontaneous fission and $β$-decay half lives of such nuclei are studied. The $α$-decay half lives of SHN with Z=102-120 are calculated in a quantum tunneling model with DDM3Y effective nuclear interaction using $Q_α$ values from three different mass formulae prescribed by Koura, Uno, Tachibana, Yamada (KUTY), Myers, Swiatecki (MS) and Muntian, Hofmann, Patyk, Sobiczewski (MMM). Calculation of spontaneous fission (SF) half lives for the same SHN are carried out using a phenomenological formula and compared with SF half lives predicted by Smolanczuk {\it et al}. Possible source of discrepancy between the calculated $α$-decay half lives of some nuclei and the experimental data of GSI, JINR-FLNR, RIKEN are discussed. In the region of Z=106-108 with N$\sim$ 160-164, the $β$-stable SHN $^{268}_{106}Sg_{162}$ is predicted to have highest $α$-decay half life ($T_α\sim 3.2hrs$) using $Q_α$ value from MMM. Interestingly, it is much greater than the recently measured $T_α$ ($\sim 22s$) of deformed doubly magic $^{270}_{108}Hs_{162}$ nucleus. A few fission-survived long-lived SHN which are either $β$-stable or having large $β$-decay half lives are predicted to exist near $^{294}110_{184}$, $^{293}110_{183}$, $^{296}112_{184}$ and $^{298}114_{184}$. These nuclei might decay predominantly through $α$-particle emission.

description: We consider stochastic difference equation x_{n+1} = x_n (1 - h f(x_n) + \sqrt{h} g(x_n) ξ_{n+1}), where functions f and g are nonlinear and bounded, random variables ξ_i are independent and h>0 is a nonrandom parameter. We establish results on asymptotic stability and instability of the trivial solution x_n=0. We also show, that for some natural choices of the nonlinearities f and g, the rate of decay of x_n is approximately polynomial: we find α>0 such that x_n decay faster than n^{-α+ε} but slower than n^{-α-ε} for any ε>0. It also turns out that if g(x) decays faster than f(x) as x->0, the polynomial rate of decay can be established exactly, x_n n^α-> const. On the other hand, if the coefficient by the noise does not decay fast enough, the approximate decay rate is the best possible result.

Universal Features of Higher-Form Symmetries at Phase Transitions

description: We investigate the behavior of higher-form symmetries at various quantum phase transitions. We consider discrete 1-form symmetries, which can be either part of the generalized concept "categorical symmetry" (labelled as $\tilde{Z}_N^{(1)}$) introduced recently, or an explicit $Z_N^{(1)}$ 1-form symmetry. We demonstrate that for many quantum phase transitions involving a $Z_N^{(1)}$ or $\tilde{Z}_N^{(1)}$ symmetry, the following expectation value $ \langle \left( \log O_\mathcal{C} \right)^2 \rangle$ takes the form $\langle \left( \log O_\mathcal{C} \right)^2 \rangle \sim - \frac{A}ε P+ b \log P $, where $O_\mathcal{C}$ is an operator defined associated with loop $\mathcal{C}$ (or its interior $\mathcal{A}$), which reduces to the Wilson loop operator for cases with an explicit $Z_N^{(1)}$ 1-form symmetry. $P$ is the perimeter of $\mathcal{C}$, and the $b \log P$ term arises from the sharp corners of the loop $\mathcal{C}$, which is consistent with recent numerics on a particular example. $b$ is a universal microscopic-independent number, which in (2+1)d is related to the universal conductivity at the quantum phase transition. $b$ can be computed exactly for certain transitions using the dualities between (2+1)d conformal field theories developed in recent years. We also compute the "strange correlator" of $O_\mathcal{C}$: $S_{\mathcal{C}} = \langle 0 | O_\mathcal{C} | 1 \rangle / \langle 0 | 1 \rangle$ where $|0\rangle$ and $|1\rangle$ are many-body states with different topological nature.

description: PandaX-4T, the new generation of the PandaX detector, is a xenon dual-phase detector with about six tons of liquid xenon as target for dark matter search. A cryogenics and xenon handling system is designed to liquify and purify this large detector. In this paper, the results on the commission of the cryogenics and gas handling system are reported. The maximum cooling power of ~ 580 W at 178 K with three cooperating coldheads has been achieved. The filling rate with an assisted liquid nitrogen cooling can reach ~ 700 kg/day. The average rate of recuperation by liquid nitrogen is around 440 kg/day. The maximum total purification speed of two circulation loops is up to ~ 155 slpm. Each loop is using a large heat exchanger with a measured heat exchange efficiency of ~ 97.5+-0.5%.

description: The hard disc system plays a fundamental role in the study of two-dimensional matters [1-3]. High-precision compressibility data from computer simulations have been reported for all the phases and phase transition regions [4-15]. In particular, Bernard and Krauth (Phys. Rev. Lett., 107, 155704, 2011) [10] presented a complete and accurate picture of the phase transitions of the hard disc system with simulation results. However, thorough descriptions of the system depend on analytical equations of state (EoS) over the entire density range. While majority of EoS published are for the stable fluid region only [1,16], few attempted the liquid-hexact transition region (Phys. Rev. Lett., 11, 241, 1963 [17]; Phys. Rev. E. 63, 042201, 2001 [18]; 74, 061106, 2006 [19]). All the EoS currently available are incapable of quantitative descriptions of the phase transitions. Here we construct a simple EoS to reproduce high-precision simulation data for all the stable liquid, liquid-hexatic transition region and hexatic phase. A global EoS is then obtained when the new EoS is smoothly united with a revisited EoS for the solid phase. Using this global equation, we are able to accurately identify all the phases and the phase transitions from the stable liquid to hexatic, then to solid phases. The liquid-hexatic transition is found to be of weak first-order, namely discontinuous in density and the Gibbs free energy while continuous in entropy and the Helmholtz free energy. The hexatic-solid transition is a continuous high-order phase transition.

description: It is shown that the so-called generic instabilities that appear in the framework of relativistic linear irreversible thermodynamics, describing the fluctuations of a simple fluid close to equilibrium, arise due to the coupling of heat with hydrodynamic acceleration which appears in Eckart's formalism of relativistic irreversible thermodynamics. Further, we emphasize that such behavior should be interpreted as a contradiction to the postulates of linear irreversible thermodynamics (LIT), namely a violation of Onsager's hypothesis on the regression of fluctuations, and not as fluid instabilities. Such contradictions can be avoided within a relativistic linear framework if a Meixner-like approach to the phenomenological equations is employed.

The English lyrics of the Henry VIII manuscript
Creators: name: Siemens, Raymond G.
Publisher: name: University of British Columbia

description: The Henry VIII MS (BL Additional MS 31,922)—a song book with lyrics by Henry VIII, Thomas Wyatt, William Cornish, and other literary figures of the early Henrician court—is a document that contributes greatly to a critical understanding of the connections between poetry, patronage, and power in early Renaissance society because of the prominence of its chief author, the King himself, and the manuscript's reflection of literary, social, and political elements of the early Tudor court. Acknowledging that the contents of the Henry VIII MS have been thoroughly treated as "words for music" by the musicologist John Stevens, whose Music and Poetry in the Early Tudor Court and Music at the Court of Henry VIII are the standard works in the area, my thesis builds on existing scholarship to treat the lyrics of H chiefly as "words," as literary texts. The chief focus of this work is the fifty-three English lyrics longer than one line, many of which are extant in the Henry VIII MS alone; the four English incipits and seventeen foreign lyrics and incipits are gathered in the appendices. Intended to be the beginning of a larger work toward the demonstration of the Henry VIII MS' importance both as a poetic and cultural document, my thesis provides the first text of the English lyrics of this manuscript intended for an audience of literary scholars and students. In introductory chapters, my thesis provides an analysis of the manuscript's content, text, and context; ultimately, my work aims to provide the basis for a more complete consideration of the Henry VIII MS' foundation in literary tradition, its influence, and its place within the court culture of early Tudor England.
