description: We consider on one hand the possibility that a supersymmetric ${\cal N}=1$ conformal gauge theory has a strongly coupled locus on the conformal manifold at which a different, dual, conformal gauge theory becomes a good weakly coupled description. On the other hand we discuss the possibility that strongly coupled theories, e.g. SCFTs in class ${\cal S}$, having exactly marginal ${\cal N}=1$ deformations admit a weakly coupled gauge theory description on some locus of the conformal manifold. We present a simple algorithm to search for such dualities and discuss several concrete examples. In particular we find conformal duals for ${\cal N}=1$ SQCD models with $G_2$ gauge group and a model with $SU(4)$ gauge group in terms of simple quiver gauge theories. We also find conformal weakly coupled quiver theory duals for a variety of class ${\cal S}$ theories: $T_4$, $R_{0,4}$, $R_{2,5}$, and rank $2n$ Minahan-Nemeschansky $E_6$ theories. Finally we derive conformal Lagrangians for four dimensional theories obtained by compactifying the E-string on genus $g>1$ surface with zero flux. The pairs of dual Lagrangians at the weakly coupled loci have different symmetries which are broken on a general point of the conformal manifold. We match the dimensions of the conformal manifolds, symmetries on the generic locus of the conformal manifold, anomalies, and supersymmetric indices. The simplicity of the procedure suggests that such dualities are ubiquitous.

description: Objective: This meta-analysis aimed to assess whether preoperative intravenous corticosteroids reduced postoperative pain in patients undergoing spinal fusion surgery. Methods: We systematically searched PubMed, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science and Google databases, from inception to March 29, 2018. Randomized controlled trials (RCTs) that compared preoperative intravenous glucocorticoids against a control treatment for the effect on pain following spinal fusion surgery were included. A meta-analysis was performed to generate a pooled risk ratio (RR) and weighted mean difference (WMD) with corresponding 95% confidence interval (CI) for discontinuous outcomes (the occurrence of postoperative nausea and vomiting [PONV] as well as surgical-site infections) and continuous outcomes (visual analog scale [VAS] scores at 12 h, 24 h, 48 h, and 72 h; total morphine consumption and the length of hospital stay), respectively. Results: Ten RCTs that compared intravenous corticosteroids versus placebo were included in our final meta-analysis. Compared with controls, intravenous corticosteroids were associated with a statistically significant reduction in pain VAS scores at 12 h, 24 h, 48 h, and 72 h. Additionally, intravenous corticosteroids decreased total morphine consumption, PONV, and the length of hospital stay. There was no significant difference between intravenous corticosteroids and controls, regarding the occurrence of infection (p > 0.05). Conclusions: In summary, our results indicated that intravenous corticosteroids not only reduce pain but also have anti-emetic effects. More studies should focus on the adverse effects of administering intravenous corticosteroids.
title: 'CLOSING THE GAP' Negotiating Alignment with Australia's First Peoples. A Comparative Discourse Analysis of the 2017 speeches presented by Australian Political Leaders.

description: In Australia, Closing the Gap is a highly profiled federal government policy aimed at closing the gap of disadvantage between Australia’s First Peoples and non-Indigenous Australians. This policy comprises of a yearly report providing statistical data addressing the progress of the initiative. As a significant parliamentary contribution towards the ideology of reconciliation in Australia, political leaders present a national address that responds to the statistical data of the report. This thesis presents a com-bined discourse analysis of the speeches presented in 2017, by Prime Minister Malcolm Turnbull and Leader of the Opposition Bill Shorten. Being a political discourse analy-sis, it focuses on the language features used by Australian political leaders to support their political ideology. Michèle Koven (2002) presented a model that explained how political leaders align (or misalign) themselves with other social actors. This research will adapt that model to identify how these leaders position themselves ideologically through their Closing the Gap speeches. Then by using critical discourse analysis, it will also present a typology of discursive strategies used in such political discourses, when negotiating an ideological alignment with Australia’s First Peoples. These two approaches will be further justified with two more supporting analyses. This compara-tive analysis contributes to a clearer understanding of how political language is used in Australia. Additionally, it contributes to the surprisingly minimal literature related to Australian political discourse analysis surrounding Indigenous issues, reconciliation and the Closing the Gap policy itself. By analysing such political speeches, reflection, engagement and empowerment then have the capacity to influence institutionalised notions of racism, poverty and class-consciousness with the view to rectifying them.

Quantum Transport in Molecular Rings and Chains

Year: 1998
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: We study charge transport driven by deformations in molecular rings and chains. Level crossings and the associated Longuet-Higgins phase play a central role in this theory. In molecular rings a vanishing cycle of shears pinching a gap closure leads, generically, to diverging charge transport around the ring. We call such behavior homeopathic. In an infinite chain such a cycle leads to integral charge transport which is independent of the strength of deformation. In the Jahn-Teller model of a planar molecular ring there is a distinguished cycle in the space of uniform shears which keeps the molecule in its manifold of ground states and pinches level crossing. The charge transport in this cycle gives information on the derivative of the hopping amplitudes.

description: Surrogate models for hotspot ignition and growth rates were presented in Part I, where the hotspots were formed by the collapse of single cylindrical voids. Such isolated cylindrical voids are idealizations of the void morphology in real meso-structures. This paper therefore investigates the effect of non-cylindrical void shapes and void-void interactions on hotspot ignition and growth. Surrogate models capturing these effects are constructed using a Bayesian Kriging approach. The training data for machine learning the surrogates are derived from reactive void collapse simulations spanning the parameter space of void aspect ratio (AR), void orientation ($θ$), and void fraction ($ϕ$). The resulting surrogate models portray strong dependence of the ignition and growth rates on void aspect ratio and orientation, particularly when they are oriented at acute angles with respect to the imposed shock. The surrogate models for void interaction effects show significant changes in hotspot ignition and growth rates as the void fraction increases. The paper elucidates the physics of hotspot evolution in void fields due to the creation and interaction of multiple hotspots. The results from this work will be useful not only for constructing meso-informed macro-scale models of HMX, but also for understanding the physics of void-void interactions and sensitivity due to void shape and orientation.

On the energy of critical solutions of the binormal flow
Creators: name: Banica, Valeria
name: Vega, Luis
Publisher: name: arXiv
Year: 2019
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: The binormal flow is a model for the dynamics of a vortex filament in a 3-D inviscid incompressible fluid. The flow is also related with the classical continuous Heisenberg model in ferromagnetism, and the 1-D cubic Schrödinger equation. We consider a class of solutions at the critical level of regularity that generate singularities in finite time. One of our main results is to prove the existence of a natural energy associated to these solutions. This energy remains constant except at the time of the formation of the singularity when it has a jump discontinuity. When interpreting this conservation law in the framework of fluid mechanics, it involves the amplitude of the Fourier modes of the variation of the direction of the vorticity.

description: The mouse t haplotype, a variant 20 cM genomic region on Chromosome 17, harbors 16 embryonic control genes identified by recessive lethal mutations isolated from wild mouse populations. Due to technical constraints so far only one of these, the tw5 lethal, has been cloned and molecularly characterized. Here we report the molecular isolation of the tw18 lethal. Embryos carrying the tw18 lethal die from major gastrulation defects commencing with primitive streak formation at E6.5. We have used transcriptome and marker gene analyses to describe the molecular etiology of the tw18 phenotype. We show that both WNT and Nodal signal transduction are impaired in the mutant epiblast, causing embryonic patterning defects and failure of primitive streak and mesoderm formation. By using a candidate gene approach, gene knockout by homologous recombination and genetic rescue, we have identified the gene causing the tw18 phenotype as Ppp2r1a, encoding the PP2A scaffolding subunit PR65alpha. Our work highlights the importance of phosphatase 2A in embryonic patterning, primitive streak formation, gastrulation, and mesoderm formation downstream of WNT and Nodal signaling.

description: The `linear orbit' of a plane curve of degree d is its orbit in P^{d(d+3)/2} under the natural action of PGL(3). We classify curves with positive dimensional stabilizer, and we compute the degree of the closure of the linear orbits of curves supported on unions of lines. Together with the results of math.AG/9805020, this encompasses the enumerative geometry of all plane curves with small linear orbit. This information will serve elsewhere as an ingredient in the computation of the degree of the orbit closure of an arbitrary plane curve.

description: Large amounts of CH4 in the form of solid hydrates are stored on continental margins and in permafrost regions. If these CH4 hydrates could be converted into CO2 hydrates, they would serve double duty as CH4 sources and CO2 storage sites. Herein, we report the swapping phenomena between global warming gas and various structures of natural gas hydrate including sI, sII, and sH through 13C solid-state nuclear magnetic resonance, and FT-Raman spectrometer. The present outcome of 85% CH4 recovery rate in sI CH4 hydrate achieved by the direct use of binary N2 + CO2 guests is quite surprising when compared with the rate of 64 % for a pure CO2 guest attained in the previous approach. The direct use of a mixture of N2 + CO2 eliminates the requirement of a CO2 separation/purification process. In addition, the simultaneously-occurring dual mechanism of CO2 sequestration and CH4 recovery is expected to provide the physicochemical background required for developing a promising large-scale approach with economic feasibility. In the case of sII and sH CH4 hydrates, we observe a spontaneous structure transition to sI during the replacement and a cage-specific distribution of guest molecules. A significant change of the lattice dimension due to structure transformation induces a relative number of small cage sites to reduce, resulting in the considerable increase of CH4 recovery rate. The mutually interactive pattern of targeted guest-cage conjugates possesses important implications on the diverse hydratebased inclusion phenomena as clearly illustrated in the swapping process between CO2 stream and complex CH4 hydrate structure.

description: $SU(2)$ gauge fields and axions can have a stable, isotropic and homogeneous configuration during inflation. However, couplings to other matter species lead to particle production, which in turn induces backreaction on and destabilization of the non-abelian and axion background. In this paper, we first study the particle production by a $SU(2)$ gauge field coupled to a massive Dirac doublet. To carry out this calculation we have made two technical improvements compared to what has been done in the literature. First, we apply the anti-symmetrization of the operators to treat particles and anti-particles on equal footing, second, to deal with the UV divergences, we apply instantaneous subtraction. We find that, the backreaction of produced fermions on the $SU(2)$ background is negligible for model parameters of observational interest. Next, we consider production of fermions due to coupling to the axion. The tree-level backreaction on the gauge fields, as well as on the axion, is vanishingly small. We also provide an estimate for the loop effects.

description: Polyelectrolytes of opposite charge in aqueous solution can undergo a liquid-liquid phase separation known as complex coacervation. Complex coacervation of ampholytic proteins with oppositely charged polyelectrolytes is of increasing interest as it results in a protein rich phase that has potential applications in food science, protein therapeutics, protein purification, and biocatalysis. However, many globular proteins do not phase separate when mixed with an oppositely charged polyelectrolyte, and those that do phase separate do so over narrow concentration, pH, and ionic strength ranges. Much of the work that has been done on complex coacervates looks at polymer-polymer systems. While there have been some initial studies showing that proteins can undergo complex coacervation, the major design factor studied to date has been overall protein charge. The tools of genetic engineering, which allow the precise tuning and placement of charge have not been used to more fully understand the design criteria for protein complex coacervation. In this dissertation, we developed a model protein library based on green fluorescent protein (GFP) to study the impact of protein net charge and charge distribution on protein phase separation with polyelectrolytes. We developed a short, ionic polypeptide sequence (6-18 amino acids) that can drive the liquid-liquid phase separation of globular proteins. We characterize the phase behavior of the protein library with a homopolymer and diblock copolymer of similar chemistry to elucidate how protein design impacts macro- and microphase separation. In these phase characterization studies, differences in the nature of phase separation as well as the salt stability of the protein coacervates with the different polymer species are identified. We finally used this model protein library to study the effects of the protein design and phase separation behavior for coacervate-based applications including intracellular protein delivery, purification, and protein stabilization.

Our main goal is to analyse the morphology of faint galaxies in order to estimate the epoch of formation of the Hubble classification sequence. The high resolution of STIS images (0.05'') is ideal for this work and enable us to perform a morphological classification and to analyse the internal structures of galaxies. We find that 40% of the 290 galaxies are early types and that there are more irregulars and ellipticals at the fainter magnitudes.

description: We investigate the implications on the dark matter (DM) signal from the AMS-02 cosmic antiproton flux. Global fits to the data are performed under different propagation and hadronic interaction models. The uncertainties from the injection spectrum, propagation effects and solar modulation of the cosmic rays are taken into account comprehensively. Since we need to investigate extended parameter regions with multiple free parameters in the fit, the machine learning method is adopted to maintain a realistic time cost. We find all the effects considered in the fitting process interplay with each other, among which the hadronic interaction model is the most important factor affecting the result. In most hadronic interaction and CR propagation models no DM signal is found with significance larger than $2σ$ except that the EPOS-LHC interaction model requires a more than $3σ$ DM signal with DM mass around $1\,\mathrm{TeV}$. For the diffusive reacceleration propagation model there is a highly significant DM signal with mass around $100\,\mathrm{GeV}$. However, the signal becomes less than $1σ$ if we take a charge dependent solar modulation potential in the analysis.

description: Collective excitations contain rich information about photoinduced transient states in correlated systems. In a Mott insulator, charge degrees of freedom are frozen, but can be activated by photodoping. The energy-momentum distribution of the charge excitation spectrum reflects the propagation of charge degrees of freedom, and provides information about the interplay among various intertwined instabilities on the time scale set by the pump. To reveal charge excitations out of equilibrium, we simulate time-resolved x-ray absorption and resonant inelastic x-ray scattering using a Hubbard model. After pumping, the former resolves photodoping, while the latter characterizes the formation, dispersion, weight, and nonlinear effects of collective excitations. Intermediate-state information from time-resolved resonant inelastic x-ray scattering (trRIXS) can be used to decipher the origin of these excitations, including bimagnons, Mott-gap excitations, doublon and single-electron in-gap states, and anti-Stokes relaxation during an ultrafast pump. This paper provides a theoretical foundation for existing and future trRIXS experiments.

description: We present new BeppoSAX LECS, MECS, and PDS observations of four flat-spectrum radio quasars (FSRQ) having effective spectral indices alpha_ro and alpha_ox typical of high-energy peaked BL Lacs. Our sources have X-ray-to-radio flux ratios on average ~ 70 times larger than ``classical'' FSRQ and lie at the extreme end of the FSRQ X-ray-to-radio flux ratio distribution. The collected data cover the energy range 0.1 - 10 keV (observer's frame), reaching ~ 100 keV for one object. The BeppoSAX band in one of our sources, RGB J1629+4008, is dominated by synchrotron emission peaking at ~ 2 x 10^16 Hz, as also shown by its steep (energy index alpha_x ~ 1.5) spectrum. This makes this object the FIRST known FSRQ whose X-ray emission is not due to inverse Compton radiation. Two other sources display a flat BeppoSAX spectrum (alpha_x ~ 0.7), with weak indications of steepening at low X-ray energies. The combination of BeppoSAX and ROSAT observations, (non-simultaneous) multifrequency data, and a synchrotron inverse Compton model suggest synchrotron peak frequencies ~ 10^15 Hz, although a better coverage of their spectral energy distributions is needed to provide firmer values. If confirmed, these values would be typical of ``intermediate'' BL Lacs for which the synchrotron and inverse Compton components overlap in the BeppoSAX band. Our sources, although firmly in the radio-loud regime, have powers more typical of high-energy peaked BL Lacs than of FSRQ, and indeed their radio powers put them near the low-luminosity end of the FSRQ luminosity function. We discuss this in terms of an anti-correlation between synchrotron peak frequency and total power, based on physical arguments, and also as possibly due to a selection effect.

description: Learning through examples is a central and widely used instructional device for teaching mathematically-based subjects such as statistical probability. However, the applications of the superficial variability of examples remain controversial. This dissertation investigates how the superficial variability of multiple examples influences students' learning and transfer of probability problem-solving. Moreover, the author discovers whether content difficulty affects the influence of examples' superficial variability. Three conditions were developed and compared: consistent-surface condition (CS), varied-surface-within-rule condition (VSWR), and varied-surface-between-rule condition (VSBR). For the purpose of exploration and methodology improvement for the dissertation study, two pilot studies were conducted. However, conflicting results were shown in those two studies. In the first pilot study, students in CS condition performed the worst. In the second pilot study, students in VSBR condition performed the worst. These conflicting results encouraged the author, even more, to conduct the dissertation study with a larger sample size and improved methodology. In this dissertation study, the author found that students' performance on the posttests in VSBR was significantly worse than in the other two conditions, which was consistent with the second pilot study, and that their performance in CS and VSWR condition was not different. Contrary to expectation, the strength of the pattern of the effect of the superficial variability of examples did not vary between the easy and difficult types of problems. Moreover, the pattern was the same when the difficulty variable was not included. These results suggested that examples' superficial consistency between different problem types promotes more effective learning than superficial variation between different problem types. The consistency can be one single cover story used multiple times for each type of problem or the same battery of varied cover stories used repeatedly for different types of problem. Moreover, the pattern of the influence of superficial variability of examples is robust among types of the problem at varying difficulty levels.

description: In this paper we review some general properties of probability distributions which exibit a singular behavior. After introducing the matter with several examples based on various models of statistical mechanics, we discuss, with the help of such paradigms, the underlying mathematical mechanism producing the singularity and other topics such as the condensation of fluctuations, the relationships with ordinary phase-transitions, the giant response associated to anomalous fluctuations, and the interplay with Fluctuation Relations.

description: Using molecular dynamics (MD) simulations in conjunction with the SPC/E water model, we optimize ionic force-field parameters for seven different halide and alkali ions, considering a total of eight ion-pairs. Our strategy is based on simultaneous optimizing single-ion and ion-pair properties, i.e., we first fix ion water parameters based on single-ion solvation free energies, and in a second step determine the cation-anion interaction parameters (traditionally given by mixing or combination rules) based on the Kirkwood-Buff theory without modification of the ion-water interaction parameters. In doing so, we have introduced scaling factors for the cation-anion Lennard-Jones (LJ) interaction that quantify deviations from the standard mixing rules. For the rather size-symmetric salt solutions involving bromide and chloride ions, the standard mixing rules work fine. On the other hand, for the iodide and fluoride solutions, corresponding to the largest and smallest anion considered in this work, a rescaling of the mixing rules was necessary. For iodide, the experimental activities suggest more tightly bound ion pairing than given by the standard mixing rules, which is achieved in simulations by reducing the scaling factor of the cation-anion LJ energy. For fluoride, the situation is different and the simulations show too large attraction between fluoride and cations when compared with experimental data. For NaF, the situation can be rectified by increasing the cation-anion LJ energy. For KF, it proves necessary to increase the effective cation-anion Lennard-Jones diameter. The optimization strategy outlined in this work can be easily adapted to different kinds of ions.
title: Chasing the Dragon: The Resilience of a Species to Climate Change in the Wet Tropics, Australia

Subjects: subject: Lizards habitat
subject: Boyd’s forest dragon (Hypsilurus boydii, Macleay)
subject: Climate change, Australia

description: Throughout history, climatic changes have caused environmental systems to shift and have influenced biotic assemblages. Most of these changes have occurred slowly, over millions of years, enabling species to either adapt to new conditions, endure the changes, or shift distributions to maintain their habitat requirements. Due to the fast rate at which climate change is currently occurring, it is unknown if species will be able to use these mechanisms to successfully respond to this rapidly changing environment. Areas that have small geographical extents, elevated uplands and high numbers of endemic species, such as the Wet Tropics in north-eastern Queensland, are expected to be particularly vulnerable to climate change. The endemic species in this at-risk area are also expected to be more susceptible to climate change. The endemic Boyd’s forest dragon (Hypsilurus boydii, Macleay) is a highly camouflaged, large lizard that inhabits lowland and upland forests from the northern to the southern boundary of the Wet Tropics. Determining how H. boydii has responded to previous climate change may give insight into how the species may respond to future climatic changes. The main aims of this study were to understand how geographical features and climate have influenced the genetic makeup, morphology and distribution of H. boydii, and to use this information to determine how climate change may influence future populations. This study used genetic analyses to identify evolutionary and geographical relationships across the Wet Tropics (north vs. south of the Black Mountain corridor [BMC] and upland vs. lowland) and within each of these regions; explore morphological variation across the regions and examine conformity to three eco-geographical rules (Bergmann’s rule, Allen’s rule, and the isolation rule); and attempt to predict species distribution patterns of the species throughout the Wet Tropics during past, present and future climatic scenarios. Seventy-seven dragons were collected from nine sites across the Wet Tropics, with a blood sample (for genetic analyses) taken from each individual, 47 of these individuals, from eight of the sites, were sampled for morphological measurements. Due to the cryptic and ambush nature of the species, sample sizes were low and uneven.

description: Urban parks provide environmental, social and economic benefits to users. A notable model that sought to integrate green spaces and create self-sufficient, healthy and pleasant places to live by combining the best aspects of urban and rural life was the garden city model. This led to the creation of many green areas across many African cities, including Kumasi, Ghana. However, considering the rapid decline and deterioration of urban parks in African cities, a key question being asked by the paper is that: is there decline in urban parks and their usage because users are not satisfied with them and thus do not patronise them? Premised on this, this paper examines the factors that influence the satisfaction and patronage of the Rattray Park in Nhyiaeso, commissioned in 2015 and remains the only functional recreational and urban green park in the city of Kumasi. Data was obtained from 237 park users along four indicators, namely (i) sociability, (ii) user and activities, (iii) accessibility and linkage and (iv) comfort and image. The results showed sociability as the most significant factor which influenced users’ satisfaction and patronage of the park, i.e. users were more concerned about the provision of facilities for recreation and socialisation. The major contribution of this paper is that sustaining urban parks will happen when there are conscious attempts by relevant stakeholders to identify, appreciate and understand the varying needs of users. This study further contributes to better understanding the garden city model and provides some suggestions to improve upon the quality and patronage of parks.
