description: Diverse mass and mixing patterns between the quarks and leptons makes it challenging to construct a simple grand unified theory of flavor. We show that SO(10) SUSY GUTs with type II seesaw mechanism giving neutrino masses provide a natural framework for addressing this issue. A simple ansatz that the dominant Yukawa matrix (the 10-Higgs coupling to matter) has rank one, appears to simultaneously explain both the large lepton mixings as well as the observed quark flavor hierarchy in these models. A testable prediction of this ansatz is the neutrino mixing, U_{e3}, which should be observable in planned long baseline experiments.

On robustness of motion control systems
Creators: name: Ha, QP
Publisher: name: University Of Tasmania
Year: 2023

description: Robustness and intelligence are becoming increasingly important in motion control systems. In multi-mass electromechanical systems, the estimation of damping capability and design of robust controllers are among very important aspects. In this thesis, conventional control methods coupled with fuzzy logic and neural networks are used to address these issues. First, damping capability of multi-mass electromechanical systems is estimated. The maximal damping and complete damping cases are determined using the generalised model for a multi-mass electromechanical system. To eliminate the load variation influence and reduce elastic vibrations, robust modal control is proposed with observer-based state feedback and feedforward compensation. The use of fuzzy logic dealing with uncertainties is investigated. Good transient performance is obtained, even in the case of changing plant parameters, by fuzzy tuning of the proportional-integral (PI) controller parameters. It is shown that PI controllers with fuzzy tuning can be used in cascade control in a two-mass system. Fuzzy tuning schemes, based on expert knowledge, can be applied to sliding mode control to accelerate the reaching phase and reduce chattering for robustness enhancement. In robust modal control , taking into account uncertainties in the plant parameters and disturbance rate of change, an improvement of observer robustness is achieved via a fuzzy tuning scheme of the predictive coefficient. Insensitivity to load variations is enhanced by continuously tuning the feedforward compensation coefficients. These fuzzy tuning schemes can be applied to robust modal control of multi-mass systems in the presence of uncertainties. Since tuning is a continuous process, exponential membership functions are used. However, with Gaussian or sigmoidal membership functions, similar results can also be obtained. Observer robustness achieved by fuzzy tuning is demonstrated to be suitable for incipient fault detection in dynamic systems. Neural network-based techniques to the problem concerned are also presented. It is shown that a neural net controller can replace the role of a feedforward controller or a fuzzy logic controller. Moreover, a neural net-based controller can be used as a classifier for recognising the error and derivative-of-error patterns, and providing an appropriate control action to improve tracking performance. The proposed controller can be used in a two-mass system without a priori knowledge of the plant. Neuro-fuzzy approach is introduced with a feedforward compensation from an observer based control loop and robust enhancement from a neural network model. Tuning is a human experience to increase robustness. Fuzzy tuning is shown to be efficient thanks to the possibility of adopting this experience. Neurotuning with learning capability will be a subject for further research.

description: Gamma-ray burst (GRB) afterglows are well described by synchrotron emission originating from the interaction between a relativistic blast wave and the external medium surrounding the GRB progenitor. We introduce a code to reconstruct spectra and light curves from arbitrary fluid configurations, making it especially suited to study the effects of fluid flows beyond those that can be described using analytical approximations. As a check and first application of our code we use it to fit the scaling coefficients of theoretical models of afterglow spectra. We extend earlier results of other authors to general circumburst density profiles. We rederive the physical parameters of GRB 970508 and compare with other authors

Language education and teacher education: The pre-service education of teachers of languages at the Centre for Education, University of Tasmania
Creators: name: de Salis, SC
Publisher: name: University Of Tasmania
Year: 2023

description: Recent developments and changes in language education have been described,and their implications explored by many theorists and practitioners with regard to their effects on language syllabuses, materials and assessment. There has been less discussion about how these changes should affect the initial preparation of those who are to teach languages in the schools. Changes discernible at present in language education include more overt support for such education and related changes in its aims and approaches which,by now,are sufficiently well-established to be summed up by the label of the 'communicative approach'. Despite this 'improvement' in the approach to language education, an examination of the student teachers' experiences as language learners during their secondary and tertiary years shows some deficiencies which have to be remedied during the Dip.Ed. year if they are to become competent and informed language teachers. The Dip.Ed. course at the Tasmanian Centre for Education is examined with particular reference to those components which introduce students to the specific areas of knowledge and skill required of language teachers. The Tasmanian course is compared with equivalent courses in other Australian states, in Britain and in the West German state of Bremen. An examination of the ways in which students are assessed suggests that there is a lack of coherence in the course which imposes an unnecessary burden on students in this area. The perennial question of the relationship between theory and practice is addressed, with reference to both language education and teacher education. Both are interlocking parts of one educational process, and several inadequacies of the Dip.Ed. course result from a destructive distinction between the two areas. There is also a failure to conceptualise the Dip.Ed. course as one part of an on-going developmental process which begins when students first become language learners, and which must continue after they have become language teachers. The concluding chapter describes ways in which the Dip.Ed. course could perform its role more effectively.

New Tests for Disruption Mechanisms of Star Clusters: Methods and Application to the Antennae Galaxies

description: We present new tests for disruption mechanisms of star clusters based on the bivariate mass-age distribution g(M,τ). In particular, we derive formulae for g(M,τ) for two idealized models in which the rate of disruption depends on the masses of the clusters and one in which it does not. We then compare these models with our Hubble Space Telescope observations of star clusters in the Antennae galaxies over the mass-age domain in which we can readily distinguish clusters from individual stars: τ\la10^7(M/10^4 M_{\odot})^{1.3} yr. We find that the models with mass-dependent disruption are poor fits to the data, even with complete freedom to adjust several parameters, while the model with mass-independent disruption is a good fit. The successful model has the simple form g(M,τ) \propto M^{-2} τ^{-1}, with power-law mass and age distributions, dN/dM propto M^{-2} and dN/dτ\proptoτ^{-1}. The predicted luminosity function is also a power law, dN/dL \propto L^{-2}, in good agreement with our observations of the Antennae clusters. The similarity of the mass functions of star clusters and molecular clouds indicates that the efficiency of star formation in the clouds is roughly independent of their masses. The age distribution of the massive young clusters is plausibly explained by the following combination of disruption mechanisms: (1) removal of interstellar material by stellar feedback, τ\la 10^7$ yr; (2) continued stellar mass loss, 10^7 yr \la τ\la 10^8 yr; (3), tidal disturbances by passing molecular clouds, τ\ga 10^8 yr. None of these processes is expected to have a strong dependence on mass, consistent with our observations of the Antennae clusters. We speculate that this simple picture also applies--at least approximately--to the clusters in many other galaxies.

Pasites villosus Friese, 1909: 438–439, holotype ♂ (type locality: Zeerust, South Africa) (ZMHB), examined.
Diagnosis
The female of S. villosa is unknown. The male can be separated from that of all other species by the combination of the following characters: metasoma at least partially red (Fig. 95B); fore legs usually black, with small reddish spots (Fig. 95A); head and mesosoma with black hair, sometimes mixed with lighter hair (Fig. 95C–D); mesoscutum sparsely, finely and shallowly punctate, very shiny (Fig. 95D); metapostnotum almost twice as wide as high (Fig. 95E); gonostylus, broad, rounded posteriorly and slightly bent inward (Fig. 96C–D).
This characteristic species was described in detail by Eardley & Brothers (1997). Thus, to facilitate the identification only images are provided (Figs 95–96) without repeating the description.
Additional material examined
None.
Distribution
Only known from the type locality Zeerust in NE South Africa. The specimen collected in Vanrhynsdorp, Namaqualand (Eardley & Brothers 1997: 404), could not be checked but it is unlikely that it represents the same species as it was collected in the Succulent Karoo biome in the winter rainfall region that is climatically completely different from the Savanna biome with summer rainfall around Zeerust.

A review of the administration of the health services in Tasmania
Creators: name: Matthews, EHG

description: The term \Health Services\" embraces a multitude of activities. It also covers a multitude of organisational sins. Since 1945 when the Executive in its wisdom decided to appoint a Director of Hospital and Medical Services a Director of Tuberculosis and.a Director of Mental Hygiene in addition to the existing position of Director of Public Health and then placed a layman the Secretary in the position of Permanent Head the sorry tale of disorganisation has increased in woe year by year until the situation as it exists in 1959 threatens a complete breakdown. My criticism of the arrangements made in 1945 has nothing to do with the appointment of a layman as Permanent Head indeed I consider a trained and experienced lay administrator to have a better chance of success than the average.medical practitioner. It is to the lack of foresight shown by those senior officers charged with advising the Government that I allude. Knowing that the Public Health Act of 1935 was framed to give wide powers to an officer also endowed with the authority of a Permanent Head under the Public Service Act1923 those senior officers apparently saw no incompatibility between the powers of the Director of Public Health now to be a subordinate officer and the new Permanent Head. If they did foresee difficulties then it seems that they took the line of least resistance by hoping that the new arrangement would be made to work somehow; but the fact remains that the Office of Director of Public Health retained all its public health powers when it became a subordinate position and thereby provided fertile ground for clashes of personality with a Permanent Head be he layman or medico."
Efficiency of protein utilization by growing chinchilla fed two levels of protein.
Creators: name: Rogier, John Charles
Publisher: name: University of British Columbia
Year: 2011

description: Six male and six female chinchilla (Chinchilla lanigera) in the late phase of growth were used to study the effects of sex, crude protein level in the ration and duration of experiment on body weight gains, digestibility of energy, dry matter, organic matter and protein and efficiency of protein utilization, as measured by biological value and net protein utilization. Two isocaloric rations of differing crude protein content (16.25% and 19.56%) were supplied ad libitum for three one-week experimental periods. The results showed that female chinchilla had significantly (P<0.05) greater body weight gains than males after adjustment for initial body weight and feed intake. There was a significant (P<0.05) effect of ration on the digestibility coefficients studied. The mean apparent digestibility coefficients for energy, dry matter, organic matter and protein for ration 1 (16.25% crude protein) were 65.09, 66.44, 67.73 and 62.83%, respectively; while for ration 2 (19.56% crude protein) the values were 67.32, 68.52, 70.21 and 73.23%, respectively. On the other hand, sex had no significant (P<0.05) effect on digestibility. There was a significant (P<0.05) effect of ration on the protein utilization indices studied. Biological value was not significantly (P<0.05) different for the two rations. The mean values for biological value and net protein utilization for ration 1 (16.25% crude protein) were 66.38 and 42.02%, respectively; while for ration 2 (19.56% crude protein) the values were 66.96 and 48.17%, respectively. On the other hand, sex had no significant (P<0.05) effect on protein utilization. The sensitivity of growing chinchilla to protein quality suggests a major role for prececal digestion and absorption although this does not preclude the synthesis and subsequent breakdown of microbial protein in the postcecal part of the gut.
Equations of state and stability of color-superconducting quark matter cores in hybrid stars

Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: The stable configurations of non-rotating and rotating hybrid stars composed of colour superconducting quark matter core are constructed using several equations of state (EOSs). We use a set of diverse EOSs for the nuclear matter which represents the low density phase. The EOSs at higher densities correspond to the quark matter in the colour superconducting phase and are computed within the NJL-like model for different values of the scalar diquark and vector current couplings strengths. The phase transition to the quark matter is computed by a Maxwell construction. We find that the stability of the hybrid stars are mainly governed by the behaviour of the EOSs for the colour superconducting quark matter. However the compositions of hybrid star are sensitive to the EOS of the nuclear matter. The value of the critical rotation frequency for the hybrid star depends strongly on the EOS of the nuclear matter as well as that for the colour superconducting quark matter. Our results indicate that the EOS for the colour superconducting quark matter can be obtained, by adjusting the parameters of the NJL model, to yield the stable configurations of the hybrid star having the maximum mass $\sim 1.5M_\odot$ in the non-rotating limit and the critical rotation frequency $\sim 1$ kHz.

Effect of multiple reusing of simulated air showers in detector simulations

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: The study of high energy cosmic rays requires detailed Monte Carlo simulations of both, extensive air showers and the detectors involved in their detection. In particular, the energy calibration of several experiments is obtained from simulations. Also, in composition studies simulations play a fundamental role because the primary mass is determined by comparing experimental with simulated data. At the highest energies the detailed simulation of air showers is very costly in processing time and disk space due to the large number of secondary particles generated in interactions with the atmosphere. Therefore, in order to increase the statistics, it is quite common to recycle single showers many times to simulate the detector response. As a result, the events of the Monte Carlo samples generated in this way are not fully independent. In this work we study the artificial effects introduced by the multiple use of single air showers for the detector simulations. In particular, we study in detail the effects introduced by the repetitions in the kernel density estimators which are frequently used in composition studies.

The use of artificial intelligence to predict road traffic noise
Creators: name: Doolan, BL
Publisher: name: University Of Tasmania
Year: 2023

description: This research has been motivated by the fact that present road traffic noise prediction models have not improved significantly since their development in the 1970s and 1980s, although road traffic noise nuisance is a significant and growing issue in Australia and elsewhere. This thesis reviews the nature of road traffic noise, its measurement, and interpretation of noise levels in terms of noise nuisance. It then examines the principal noise propagation influences that are described by road traffic noise prediction models such as ST AM SON and TNOISE, and outlines how these quasi-empirical models produce noise level predictions. Present road traffic noise prediction models are essentially pattern recognition tools, but while they perform satisfactorily for very simple situations, accurate noise prediction in more complex situations is beyond their ability. However, artificial intelligence pattern recognition tools have proven their power and usefulness in a variety of applications in recent years, and this thesis examines the hypothesis that a neural network approach to predicting road traffic noise offers a way to move forward in noise impact assessment. A simple two-layer feed-forward neural network architecture is found to be able to easily mimic present road traffic noise prediction models, with tangent-sigmoidal transfer functions specified for the input layer of 20-30 neurons, and a linear transfer function specified for the single output neuron. A priori rescaling of input values to roughly match the requirements of the transfer function facilitates the neural network training using a backpropagation algorithm with momentum and adaptive learning. Ways of avoiding the problem of overfitting are discussed. A case study based on a 1993 noise impact assessment project is presented that demonstrates that a neural network can easily be trained from fairly limited field data to satisfactorily predict road traffic noise in site-specific situations, and the case study was one in which a model such as STAMSON or TNOISE is not able to perform well. The effort and expertise needed for this exercise is comparable to an air emission dispersion modelling exercise, a conclusion that should prove of great interest to road and environment authorities. The thesis then proposes a strategy whereby grid-based neural networks can be developed to enable road traffic noise prediction in complex situations. The methodology is explained with the aid of a barrier adjustment calculation. The development of such a model for a sitespecific situation is quite straightforward, but there is also clear potential to develop a generic 2-dimension modelling capability. The basic approach to this parallels the modelling strategy of present noise prediction models, but with reference sound levels and adjustments referred to a grid, and determined using neural networks.

description: Morphogen profiles play a vital role in biology by specifying position in embryonic development. However, the factors that influence the shape of a morphogen profile remain poorly understood. Since morphogens should provide precise positional information, one significant factor is the robustness of the profile to noise. We compare three classes of morphogen profiles (linear, exponential, algebraic) to see which is most precise when subject to both external embryo-to-embryo fluctuations and internal fluctuations due to intrinsically random processes such as diffusion. We find that both the kinetic parameters and the overall gradient shape (e.g. exponential versus algebraic) can be optimised to generate maximally precise positional information.

description: Path-integral molecular dynamics simulations in the isothermal-isobaric (NPT) ensemble have been carried out to study the dependence of the lattice parameter of 3C-SiC upon isotope mass. This computational method allows a quantitative and nonperturbative study of such anharmonic effect. Atomic nuclei were treated as quantum particles interacting via a tight-binding-type potential. At 300 K, the difference Delta a between lattice parameters of 3C-SiC crystals with 12C and 13C amounts to 2.1 x 10^{-4} A. The effect due to Si isotopes is smaller, and amounts to 3.5 x 10^{-5} A when replacing 28Si by 29Si. Results of the PIMD simulations are interpreted in terms of a quasiharmonic approximation for the lattice vibrations.

Shear viscosity to entropy density ratio of a relativistic Hagedorn resonance gas

description: The new state of matter produced at Relativistic Heavy Ion Collider reveals a strongly coupled quark-gluon plasma with an extremely small shear viscosity to entropy density ratio eta/s. We calculate the eta/s of an equilibrated hadron matter characterized by a relativistic hadron resonance gas with a Hagedorn mass spectrum that grows exponentially with the hadron mass. We find with increase in temperature of the system the eta/s value decreases due to rapid increase in the multiplicity of massive resonances. In the vicinity of the critical temperature for deconfinement transition, the minimum value of eta/s in the Hagedorn resonance gas is found to be consistent with the current estimates for a strongly coupled quark-gluon plasma.

description: How does one go about ridding society of its obvious evils, that is, the great contrasts between rich and poor, the privileged and the deprived and even the healthy and the sick? By the late nineteenth century a wide spectrum of European, and indeed world, thought had come to identify these evils with the capitalist mode of production, a tribute certainly to the analysis of society provided by Marx and Engels, but, more than that, an admission that if the capitalist mode of production could be overthrown and replaced by a new social order in which the worker no longer had seized from him the products of his labour by exploiters, there would be sufficient of the better things of life for all men.Men would become equal and even the division into healthy and sick might be to a large extent eliminated, for so many health problems were attributed to the squalid conditions in which the poor lived and their inability to afford medical care.

Design and development of an oblique incidence interferometer
Creators: name: Bajaj, Vijay Kumar
Publisher: name: University of British Columbia
Year: 2011

description: Interferometry offers great scope in the study of surface topography and small surface displacements. The fundamentals of surface as encountered in engineering practice and a few of the optical methods available for the metrology of surface have been reviewed. In particular, Oblique Incidence Interferometry has been developed in detail for the study of relatively rough surfaces. The relationship between this method and the recent and more general method of holography has been explained. Some preliminary experiments were conducted to gain a feeling for the latter two methods and an oblique incidence interferometer was designed, constructed, and tested for its suitability for measuring industrial surfaces of approximately 22 inches in span from the following aspects: 1. The determination of surface topography of rough surfaces; 2. The measurement of small surface displacements; 3. The execution of forward scatter and back scatter holography for normal qualitative recording and subsequent comparison—holographic interferometry. A rough turned surface of a 12 inch diameter circular aluminium plate was examined. Small surface displacements of the same plate were measured and compared with theoretical predictions. Further holographic interferometry was performed on a turbine blade. Some of the difficulties encountered, such as the significance of diffraction effects at edges and marks on the surface and the determination of scale were studied and are discussed. Future studies on tubes and cylinders are discussed.

description: Geometry arising from two diffusion operators (smooth semi-elliptic, second order differential operators) on different spaces but intertwined by a smooth map is described. Particular cases arise from Riemannian submersions when the operators are Laplace-Beltrami operators, from equivariant operators on the total space of a principal bundle, and for the operators on the diffeomorphism group arising from stochastic flows. Classical non-linear filtering problems also lead to such conffigurations. A basic tool is the, possibly, non-linear "semi-connection" induced by this set up, leading to a canonical decomposition of the operator on the domain space. Topics discussed include: generalised Wietzenbock curvatures arising in the equivariant case, skew -product decompositions of diffusion processes, conditioned processes, classical filtering, decomposition of stochastic flows, and connections determined by stochastic differential equations.

An investigation into stress-induced analgesia and pain during non-suicidal self-injury
Creators: name: Dykes, K
Publisher: name: University Of Tasmania
Year: 2023

description: The present study investigated the mechanisms of non-suicidal self-injury (NSSI) and the differences in the experience of pain during the act. In particular, the study investigated the potential explanations as to why some individuals experience pain during NSSI whereas others report an absence of pain during the act. Of particular interest was the impact of dissociative experiences and a history of trauma on the experience of pain during NSSI. A personalised, staged guided imagery methodology was employed to assess the psychological and psychophysiological reactions of 20 individuals with a history of NSSI. Furthermore, a cold pressor test was used to investigate individual‚ÄövÑvºs responses to painful stimuli. Unexpectedly, both individuals who do and do not feel pain during the act experienced a consistent pattern and strength of tension reduction following NSSI. Additionally, when investigating responses to painful stimuli in individuals who do and do not feel pain during NSSI, there were no significant differences in threshold, tolerance or perception of pain. When considering the impact of dissociation on the experience of pain during NSSI (n = 30), contrary to the hypothesis, there were no differences in the strength or frequency of individuals‚ÄövÑvº dissociative experiences. The relationship between trauma and pain during NSSI was then investigated in 52 individuals. It was found that individuals who experience a lack of pain during NSSI reported significantly more childhood abuse and trauma, higher levels of neglect and punishment, and a more negative home environment than individuals who feel pain during the act. The results add to the literature on, and provide interesting insights into the complex relationship between childhood abuse and trauma, NSSI and pain.
Non-adiabatic pumping through interacting quantum dots

description: We study non-adiabatic two-parameter charge and spin pumping through a single-level quantum dot with Coulomb interaction. For the limit of weak tunnel coupling and in the regime of pumping frequencies up to the tunneling rates, $Ω\lesssim Γ/\hbar$, we perform an exact resummation of contributions of all orders in the pumping frequency. As striking non-adiabatic signatures, we find frequency-dependent phase shifts in the charge and spin currents, which allow for an effective single-parameter pumping as well as pure spin without charge currents.

description: Magnesium dihydride ($\mgh$) stores 7.7 weight % hydrogen, but it suffers from a high thermodynamic stability and slow (de)hydrogenation kinetics. Alloying Mg with lightweight transition metals (TM = Sc, Ti, V, Cr) aims at improving the thermodynamic and kinetic properties. We study the structure and stability of Mg$_x$TM$_{1-x}$H$_2$ compounds, $x=[0$-1], by first-principles calculations at the level of density functional theory. We find that the experimentally observed sharp decrease in hydrogenation rates for $x\gtrsim0.8$ correlates with a phase transition of Mg$_x$TM$_{1-x}$H$_2$ from a fluorite to a rutile phase. The stability of these compounds decreases along the series Sc, Ti, V, Cr. Varying the transition metal (TM) and the composition $x$, the formation enthalpy of Mg$_x$TM$_{1-x}$H$_2$ can be tuned over the substantial range 0-2 eV/f.u. Assuming however that the alloy Mg$_x$TM$_{1-x}$ does not decompose upon dehydrogenation, the enthalpy associated with reversible hydrogenation of compounds with a high magnesium content ($x=0.75$) is close to that of pure Mg.

description: The role that various areas of law may play in addressing sustainability objectives is currently under debate. In competition law, the topic is part of a larger discussion about the use of antitrust law to further non-economic objectives and its alignment with the traditional consumer welfare standard. The process of revising the Horizontal Block Exemption Regulations provided an opportunity for the European Commission to address sustainability agreements. The new Horizontal Guidelines, adopted in June 2023, include a specific chapter dedicated to them. This paper analyses the main features of this chapter, within which a significant part is devoted to sustainability standards. The analysis highlights that the Commission has cautiously confirmed its traditional stance while considering broader forms of benefits in the competitive assessment, providing a soft safe harbour for sustainability standards, and maintaining a certain degree of flexibility.

Essays on inequality and macroeconomic policies
Creators: name: Yan, Weinan
Publisher: name: No Publisher Supplied
Year: 2020

description: This dissertation studies the effects of inequality on macroeconomic policies. Inequality has become a very important issue, but there are few studies about the effects of inequality on monetary and fiscal policies. This dissertation attempts to fill this gap. The dissertation consists of three chapters. Chapter 1, “Inequality and the Interwar Gold Standard” studies the relationship between inequality and the interwar gold standard. Many economic historians have argued that adherence to the gold standard was an important obstacle to recovery from the Great Depression. It is therefore important to understand the factors that affected a country’s determination to remain on gold. Many proximate determinants of adherence have been identified, including democracy, creditor status, sterling bloc membership and the structure of a country’s trade network. Here I explore a neglected but fundamental determinant: inequality. I find that countries with higher inequality at the start of the Great Depression remained on gold longer than countries with lower inequality. I conduct a survival analysis using two discrete time hazard models to test the effect of inequality on the probability of exiting gold for each country. The paper lays out the econometric evidence for this relationship and analyzes the underlying political economy that explains the relationship between inequality and adherence to the gold standard. Four detailed case studies of the relationship are provided: Australia, New Zealand, France and the U.S., four cases that illustrate the general proposition. Chapter 2, “The Short-Run and Long-Run Effects of Inequality on Inflation in the United States” studies effects of inequality on inflation in the in the United States. It uses a wide range of inequality measures. The cointegration test provides evidence that there exists a long-run relationship between inequality and inflation in the United States. The Vector Error Correction Model (VECM) and impulse response function indicate that inequality has a negative effect on inflation in the long run, however, the short-run effect is not significant. Chapter 3, “The Short-Run and Long-Run Effects of Inequality on Inflation- Panel Data Analysis” expands the dataset to several panels and studies the effects of inequality on inflation. It uses several panels of international data covering different periods and monetary regimes. The Autoregressive Distributed Lag (ARDL) model shows a negative long-run relationship between inequality and inflation, and the Arellano-Bond GMM estimator reveals a negative causal effect running from inequality to inflation in the short run. The paper lays out the econometric evidence for these relationships and analyzes the underlying political economy that explains the relationships between inequality and inflation.

description: We discuss the spin-orbit orientation of the Fomalhaut planetary system composed of a central A4V star, a debris disk, and a recently discovered planetary companion. We use spectrally resolved, near-IR long baseline interferometry to obtain precise spectro-astrometric measurements across the brG absorption line. The achieved astrometric accuracy of 3 nu-as and the spectral resolution R=1500 from the AMBER/VLTI instrument allow us to spatially and spectrally resolve the rotating photosphere. We find a position angle PAstar=65deg pm 3deg for the stellar rotation axis, perfectly perpendicular with the literature measurement for the disk position angle (PAdisk=156deg pm 0.3deg). This is the first time such test can be performed for a debris disk, and in a non-eclipsing system. Additionally, our measurements suggest unexpected backward-scattering properties for the circumstellar dust grains. Our observations validate the standard scenario for star and planet formation, in which the angular momentum of the planetary systems are expected to be collinear with the stellar spins.

description: We propose to use the Kolmogorov-Smirnov test to uncover non-statistical differences between events created in heavy ion collisions within the same centrality class. The advantage of the method over other approaches which are currently in use, is that it is sensitive to any difference between the events and is not restricted to simple moments of the distribution of hadrons. The particular application examined here is the identification of the fireball decay due to spinodal fragmentation and/or sudden rise of the bulk viscosity.
