description: The dipole ordering in Sn(Pb)$_2$P$_2$S(Se)$_6$ materials may be tuned by chemical substitution realizing a ferroelectric quantum phase transition and quantum glassy or relaxor type phenomena on different parts of the phase diagram. The introduction of Ge impurity increases the temperature of the phase transitions and initiates a more pronounced Ising type critical anomaly in Sn$_2$P$_2$S$_6$ crystal, does not shift the coordinate of the Lifshitz point $x_{\textrm {LP}}$ in Sn$_2$P$_2$(Se$_x$S$_{1-x}$)$_6$ mixed crystals, induces the appearance of a ferroelectric phase transition in quantum paraelectrics Pb$_2$P$_2$S$_6$ and inhomogeneous polar ordering in (Pb$_{0.7}$Sn$_{0.3}$)$_2$P$_2$S(Se)$_6$ crystals. For Pb$_2$P$_2$S$_6$ crystal, the real part of the dielectric susceptibility in the quantum critical regime varies as $1/T^2$ instead of the expected $1/T^3$ behavior for uniaxial materials. This can be partially explained by a screening phenomenon in the semiconductor materials of the Sn(Pb)$_2$P$_2$S(Se)$_6$ system, which weakens the long range electric dipole interactions, and also provides, at high temperatures, a critical behavior near the Lifshitz point (studied by thermal diffusivity) similar to the one predicted in the case of systems with short range interactions. At low temperatures, a quantum critical behavior in Pb$_2$P$_2$S$_6$ crystal can be established by the nonlinear coupling between polar and antipolar fluctuations. An increase in thermal conductivity is induced by Ge impurity in Pb$_2$P$_2$S$_6$ crystal, which is explained through the weakening of the acoustic phonons resonance scattering by soft optic phonons because of the appearance of ferroelectric phase polar clusters.
Consistent Definitions of Flux and Electric and Magnetic Current in Abelian Projected SU(2) Lattice Gauge Theory

description: Through the use of a lattice U(1) Ward-Takahashi identity, one can find a precise definition of flux and electric four-current that does not rely on the continuum limit. The magnetic four-current defined for example by the DeGrand-Toussaint construction introduces order a^2 errors in the field distributions. We advocate using a single definition of flux in order to be consistent with both the electric and magnetic Maxwell's equations at any lattice spacing. In a U(1) theory the monopoles are slightly smeared by this choice, i.e. are no longer associated with a single lattice cube. In Abelian projected SU(2) the consistent definition suggests further modifications. For simulations in the scaling window, we do not foresee large changes in the standard analysis of the dual Abrikosov vortex in the maximal Abelian gauge because the order a^2 corrections have small fluctuations and tend to cancel out. However in other gauges, the consequences of our definitions could lead to large effects which may help in understanding the choice of gauge. We also examine the effect of truncating all monopoles except for the dominant cluster on the profile of the dual Abrikosov vortex.

description: While the positive effect of economic integration on trade is commonly accepted, we still lack a proper understanding of the complex patterns behind this phenomenon. In particular, it is important to better understand how the structure of trade linkages evolves. This is because there are reasons to assume that countries within an economic integration agreement do not trade with each other on random basis. On the contrary, one may argue that they select trade linkages and this choice may be driven by various factors. In this paper we test two specific predictions that originate from the recent literature and which could be informative in this respect. First, we show that the size of the initial trade network is positively correlated with building new trade linkages. In other words, a greater initial number of trading partners facilitates establishing new connections. Second, we also provide some evidence in support of the hypothesis that the evolution of trade network for a given country depends on the trade network of its trading partners. In this case however, our results are slightly less robust.
Effects of counterion fluctuations in a polyelectrolyte brush

description: We investigate the effect of counterion fluctuations in a single polyelectrolyte brush in the absence of added salt by systematically expanding the counterion free energy about Poisson-Boltzmann mean field theory. We find that for strongly charged brushes, there is a collapse regime in which the brush height decreases with increasing charge on the polyelectrolyte chains. The transition to this collapsed regime is similar to the liquid-gas transition, which has a first-order line terminating at a critical point. We find that for monovalent counterions the transition is discontinuous in theta solvent, while for multivalent counterions the transition is generally continuous. For collapsed brushes, the brush height is not independent of grafting density as it is for osmotic brushes, but scales linear with it.

description: Foot and Mouth Disease (FMD) poses a serious threat to the agricultural sector due to its highly contagious nature. Outbreaks of FMD can lead to substantial disruptions to livestock markets due to loss of production and access to international markets. In a previously FMD-free country, the use of vaccination to augment control of an FMD outbreak is increasingly being recognised as an alternative control strategy to direct slaughtering (Stamping-Out). Specific choice of eradication strategies depends on their costs and benefits. Economic impact assessments are often based on Benefit-Cost frameworks, which provide detailed information on the changes in profit for a farm or budget implications for a government (Rich et al., 2005). However, this framework cannot capture price changes caused by the outbreak. Market equilibrium and hence prices are expected to change due to the outbreak as both production and demand (especially export) would be disrupted. The implications of a particular control strategy on the different market aspects can be positive or negative. Therefore, modelling systems able to capture the market impacts are needed for strategy evaluation. This paper provides assessment of sectoral level impacts of the eradication choices of FMD outbreaks, which are typically not available from Benefit-Cost frameworks, in the context of the UK. The FAPRI-UK model, a partial equilibrium model of the agricultural sector, is utilised to investigate market outcomes of different control strategies (namely, Stamping-Out, and Vaccinate-to-Die) in the case of FMD outbreaks. The outputs from the simulations of the EXODIS epidemiological model (number of animals culled/vaccinated and duration of outbreak) are used as inputs within the economic model to capture the overall price impact of the animal destruction and export ban.

description: A model of optimal control of ventilation has recently been developed for humans. This model highlights the importance of the localization of the transition between a convective and a diffusive transport of respiratory gas. This localization determines how ventilation should be controlled in order to minimize its energetic cost at any metabolic regime. We generalized this model to any mammal, based on the core morphometric characteristics shared by all mammalian lungs and on their allometric scaling from the literature. Since the main energetic costs of ventilation are related to convective transport, we prove that, for all mammals, the localization of the shift from a convective transport to a diffusive transport plays a critical role on keeping this cost low while fulfilling the lung function. Our model predicts for the first time the localization of this transition in order to minimize the energetic cost of ventilation, depending on mammal mass and metabolic regime. From this optimal localization, we are able to predict allometric scaling laws for both tidal volumes and breathing rates, at any metabolic rate. We ran our model for the three common metabolic rates -- basal, field and maximal -- and showed that our predictions reproduce accurately experimental data available in the literature. Our analysis supports the hypothesis that mammals allometric scaling laws of tidal volumes and breathing rates at a given metabolic rate are driven by a few core geometrical characteristics shared by mammalian lungs and by the physical processes of respiratory gas transport.

description: We use a rich yearly time series dataset to estimate demand and supply price- and cross-elasticities on the market for construction round wood in Switzerland, on the period 1949-2013. We consider both short term and long term relationships, thanks to the Error Correction Model and correct for the price endogeneity using a supply-demand equations system estimated with the 3 Stages Least Squares approach. Given the importance of wood products in CO2 sequestration, an increase in the use of local wood for construction purposes may help reducing the CO2 net emissions. Yet, the Swiss forest industry suffers from the low price of wood and is unwilling to produce more timber, despite the important potential of wood mobilization in Switzerland. Financial incentives may help meeting the goals of both environmental and economic sustainability, if actors respond to price changes. We find that both demand and supply are sensitive to price changes in the long and short run but that the simultaneous increasing demand for energy wood may have counterproductive impacts on the construction wood production.
Dynamical bar-mode instability of differentially rotating stars: Effects of equations of state and velocity profiles

description: As an extension of our previous work, we investigate the dynamical instability against nonaxisymmetric bar-mode deformations of differentially rotating stars in Newtonian gravity varying the equations of state and velocity profiles. We performed the numerical simulation and the followup linear stability analysis adopting polytropic equations of state with the polytropic indices n=1, 3/2, and 5/2 and with two types of angular velocity profiles (the so-called j-constant-like and Kepler-like laws). It is confirmed that rotating stars of a high degree of differential rotation are dynamically unstable against the bar-mode deformation, even for the ratio of the kinetic energy to the gravitational potential energy $β$ of order 0.01. The criterion for onset of the bar-mode dynamical instability depends weakly on the polytropic index n and the angular velocity profile as long as the degree of differential rotation is high. Gravitational waves from the final nonaxisymmetric quasi-stationary states are calculated in the quadrupole formula. For proto-neutron stars of mass $1.4M_{\odot}$, radius $\sim 30$ km and $β\alt 0.1$, such gravitational waves have the frequency of $\sim$ 600--1,400 Hz, and the effective amplitude is larger than $10^{-22}$ at a distance of about 100 Mpc irrespective of n and the angular velocity profile.

description: Nuclear effective field theories (EFTs) have been developed over the last quarter-century with considerable impact on the description of light and even medium-mass nuclei. At the core of any EFT is a systematic expansion of observables, which is usually obtained from a rule based on an assumption of naturalness. I discuss naturalness in the context of the relatively weak binding of nuclei, where discrete scale invariance plays a role in the emergence of complexity.

description: The scope for improving the economic and financial performance of beef businesses by changing breeder herd management practices and reproduction efficiency was investigated across a range of regions in northern Australia from early 2013 to late 2015. Case studies and desktop analyses were applied to identify the relative and absolute value of altering management strategies such as: weaning, pregnancy testing, herd segregation, supplementation, genetic improvement, mating, culling, infrastructure investment, enterprise selection, herd bull use and age of turnoff. In more extensive herds with uncontrolled mating, emphasis was placed on answering the question: what are the costs of out-of-season calving? The project provided insight into: • the value of changing management strategies, • the capacity of industry participants to appropriately assess the value of strategies, • the nature and value of indicators applied by industry to assess strategies. Analysis identified that a relatively large proportion (>50%) of the changes in management strategy selected by project co-operators were unlikely to improve profit, with about one-third likely to significantly reduce profit. The inability of beef business managers to nominate profitable changes in management strategy was due, in large part, to a lack of appropriate skills in identifying the most profitable option for change and to the use of spurious indicators unlikely to assist in the identification of profitable change. The provision of decision support frameworks that incorporate an appropriate disciplinary balance and focus on developing skills and knowledge are identified as important in helping beef enterprise managers make better choices.

description: In a recent paper 1/ we examined the relationship between inflation and unemployment and the effect of these upon the poor. The purpose of that study was to suggest that neither a tax increase or a cutback in government spending in FY 1967 is desirable or necessary unless the 3% unemployment level is approached. The logic involves three steps. We cone hided that : 1. The acceleration of inflation may ·be both small and one-time only. There is neither a prior nor empirical justification for believing that price increases will enter a continuing spiral. 2. That further decreases in unemployment are very important to the poort and 3. That inflation hurts the poor only very little. This paper will discuss certain aspects of point 2 and then expand in detail and supplement the arguments underlying point 3. The discussion will be keyed less to the present condition of the economy than was the previous paper.
Two-step dynamics of photoinduced phonon entanglement generation between remote electron-phonon systems

description: The generation of quantum entanglement between phonons in photoirradiated remote electron-phonon systems is numerically studied. Upon excitation by a visible/ultraviolet laser pulse, the entanglement of electrons is immediately generated and that of phonons follows via electron-phonon interactions, i.e., the entanglement generation of phonons is a two-step process. Therefore, it is important to design the temporal properties of incident optical pulses in order to control the entanglement of electrons and/or phonons. These features are revealed by the quantum mutual information and the composite modes derived from the Heisenberg equation of motion. The calculated results also show that the dynamics of the phonon entanglement can be observed by time-resolved spectroscopy on the scattered light.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: The decoupling of epitaxial factors influencing on the dynamic instabilities of AlGaN/GaN metal-insulator semiconductor high electron mobility transistors is investigated. Three different sets of samples have been analyzed by means of dynamic instabilities in the threshold voltage (V$_{\mathrm{th}}$ shift). Secondary ion mass spectroscopy, steady-state photoluminescence (PL) measurements have been performed in conjunction with electrical characterization. The device dynamic performance is found to be significantly dependent on both the C concentration close to the channel as well as on the distance between the channel and the higher doped C region. Additionally, we note that experiments studying trapping should avoid large variations in the sheet carrier density (N$_{\mathrm{s}}$). This change in the N$_{\mathrm{s}}$ itself has a significant impact on the V$_{\mathrm{th}}$ shift. This experimental trends are also supported by a basic model and device simulation. Finally, the relationship between the yellow luminescence (YL) and the band edge (BE) ratio and the V$_{\mathrm{th}}$ shift is investigated. As long as the basic layer structure is not changed, the YL/BE ratio obtained from steady-state PL is demonstrated to be a valid method in predicting trap concentrations in the GaN channel layer.

description: Given a finite dimensional Lie algebra $L$ let $I$ be the augmentation ideal in the universal enveloping algebra $U(L)$. We study the conditions on $L$ under which the $Ext$-groups $Ext (k,k)$ for the trivial $L$-module $k$ are the same when computed in the category of all $U(L)$-modules or in the category of $I$-torsion $U(L)$-modules. We also prove that the Rees algebra $\oplus _{n\geq 0}I^n$ is Noetherian if and only if $L$ is nilpotent. An application to cohomology of equivariant sheaves is given.

description: Many rural areas, like their urban counterparts, face problems with their local infrastructure (public services and facilities). The challenge for rural areas, though, is different—that of building and financing new bridges, roads, waterworks, and the like rather than repairing deteriorating facilities. Such problems are especially acute during periods of high population growth because of the additional demands placed on the system. This article describes the findings of a recent survey of rural facilities in order to: -- Give a national quantitative perspective to a problem that had previously been defined only by local anecdotal evidence. -- Establish a benchmark level of public services and facilities against which future progress can be charted.
Linear Stability Analysis of Differentially Rotating Polytropes -- New results for the m = 2 f-mode dynamical instability --

description: We have studied the $f$-mode oscillations of differentially rotating polytropes by making use of the linear stability analysis. We found that the critical values of $T/|W|$ where the dynamical instability against the $m = 2$ $f$-mode oscillations sets in decrease down to $T/|W| \sim 0.20$ as the degree of differential rotation becomes higher. Here $m$ is an azimuthal mode number and $T$ and $W$ are the rotational energy and the gravitational potential energy, respectively. This tendency is almost independent of the compressibility of the polytropes. These are the {\it first exact results} of the linear stability analysis for the occurrence of the dynamical instability against the $m = 2$ $f$-modes.

description: We demonstrate voltage-tunable thermo-optic bi- and tri-stability in silicon photonic microring resonators with lateral p-i-n junctions and present a technique for characterizing the thermo-optic transient response of integrated optical resonators. Our method for thermo-optic transient response measurement is applicable to any integrated photonics platform and uses standard equipment. Thermo-optic relaxation in encapsulated waveguides is found to be approximately logarithmic in time, consistent with the analytic solution for 2D heat diffusion. We develop a model for thermo-optic microring multi-stability and dynamics which agrees with experiment data over a wide range of operating conditions. Our work highlights the fundamental connection in semiconductor waveguides between active free-carrier removal and thermo-optic heating, a result of particular relevance to Kerr soliton state stability and on-chip frequency comb generation. The devices studied here were fabricated in a CMOS foundry process and as a result our model is useful for design of silicon photonic waveguide devices.

description: The work treats smoothing and dispersive properties of solutions to the Schrodinger equation with magnetic potential. Under suitable smallness assumption on the potential involving scale invariant norms we prove smoothing - Strichartz estimate for the corresponding Cauchy problem. An application that guarantees absence of pure point spectrum of the corresponding perturbed Laplace operator is discussed too.

description: The three-body energy-dependent effective interaction given by the Bloch-Horowitz (BH) equation is evaluated for various shell-model oscillator spaces. The results are applied to the test case of the three-body problem (triton and He3), where it is shown that the interaction reproduces the exact binding energy, regardless of the parameterization (number of oscillator quanta or value of the oscillator parameter b) of the low-energy included space. We demonstrate a non-perturbative technique for summing the excluded-space three-body ladder diagrams, but also show that accurate results can be obtained perturbatively by iterating the two-body ladders. We examine the evolution of the effective two-body and induced three-body terms as b and the size of the included space Lambda are varied, including the case of a single included shell, Lambda hw=0 hw. For typical ranges of b, the induced effective three-body interaction, essential for giving the exact three-body binding, is found to contribute ~10% to the binding energy.

description: We show that the following five categories are equivalent: (1) the opposite category of commutative von Neumann algebras; (2) compact strictly localizable enhanced measurable spaces; (3) measurable locales; (4) hyperstonean locales; (5) hyperstonean spaces. This result can be seen as a measure-theoretic counterpart of the Gelfand duality between commutative unital C*-algebras and compact Hausdorff topological spaces.

description: Two mechanisms for the breakdown of step flow growth, in the sense of the appearance of steps of opposite sign to the original vicinality, are studied by kinetic Monte Carlo simulations and scaling arguments. The first mechanism is the nucleation of islands on the terraces, which leads to mound formation if interlayer transport is sufficiently inhibited. The second mechanism is the formation of vacancy islands due to the self-crossing of strongly meandering steps. The competing roles of the growth of the meander amplitude and the synchronization of the meander phase are emphasized. The distance between vacancy islands along the step direction appears to be proportional to the square of the meander wavelength

FROM WARRIORS TO ADMINISTRATORS: CAPITAL AND COERCION IN THE EARLY PROCESS OF STATE FORMATION IN ARABIA (1900-1938)
Creators: name: Alowfi, Ahmed Saad
Publisher: name: American University
Year: 2023

description: The major scholarship on state formation tends to privilege external (colonial or post-colonial) factors when it addresses cases of non-European states. Contributing to a growing literature that complicates such a tendency, this thesis challenges the standard view of the rise of Arab national states by demonstrating how the formation of the Saudi Arabian modern state was primarily driven by internal factors. It suggests that the emergence of a centralized state in the early twentieth century Arabia was largely a response to internal threats rather than a consequence of war threats or a construction of a colonial project. Based on secondary materials and a sample of primary documents, the thesis presents a historical analysis of the period from 1900 to 1938. It utilizes Charles Tilly's conceptual framework that highlights the effect of war and revenues in the development of the national state. The findings indicate that, in conformity with Charles Tilly's stipulations, the coercive-intensive state in the phase of expansion (1902-1924) yielded an indirect rule of a tribute tanking empire. The transition from an empire-state to a centralized, bureaucratized national state in the early 1930s, however, was not, the findings suggest, determined by external threats, made insignificant by the imperial protection of the British. The episode of the Ikhwan Revolt, the study shows, was decisive in transforming the polity into a national state.

description: Cameron {\it et al.}~2019 (hereafter C19) recommends a more cautious and rigorous approach to statistical analysis in astronomy. We welcome this particular side of their communication as it helps stimulating the effort towards the adoption of better statistical methods in galaxy rotation curves, an effort to which we contributed with Rodrigues {\it et al.}~2018 (hereafter R18). Indeed, R18 was the first work that, in order to conclude on the universality of the acceleration scale $a_0$, studied the posterior distributions on $a_0$ of a large set of galaxies. As C19 agrees, the credible intervals were found within the Bayesian framework, that is, the marginalized posteriors on $a_0$ were found using Bayes' theorem to update the priors in light of the observational data; this process was done without introducing any approximation. Considering R18, C19 also remarks that: i) better methods to select the nuisance parameters and the corresponding priors could be used; ii) a quality cut based on $χ^2$ values should not be used, and iii) the compatibility of the posteriors should be assessed in a more robust way. In the following, after first clarifying the context of our work, we address these criticisms.

description: We performed computer simulations based on a two-dimensional Distinct Element Method to study granular systems of magnetized spherical particles. We measured the angle of repose and the surface roughness of particle piles, and we studied the effect of magnetization on avalanching. We report linear dependence of both angle of repose and surface roughness on the ratio $f$ of the magnetic dipole interaction and the gravitational force (\emph{interparticle force ratio}). There is a difference in avalanche formation at small and at large interparticle force ratios. The transition is at $f_c \approx 7$. For $f < f_c$ the particles forming the avalanches leave the system in a quasi-continuous granular flow (\emph{granular regime}), while for $f > f_c$ the avalanches are formed by long particle clusters (\emph{correlated regime}). The transition is not sharp. We give plausible estimates for $f_c$ based on stability criteria.
