description: We analyze quantitatively the tuning of composite Higgs models with partial compositeness and its interplay with the predicted Higgs mass. In this respect we identify three classes of models, characterized by different quantum numbers of the fermionic colored resonances associated with the top quark, the so-called top partners. The main result of this classification is that in all models with moderate tuning a light Higgs, of 125 GeV mass, requires the presence of light top partners, around 1 TeV. The minimal tuning is comparable to the one of the most attractive supersymmetric models in particular the ones realizing Natural SUSY. This gives further support to an extensive program of top partners searches at the LHC that can already probe the natural region of composite Higgs models.

description: Project develops a stochastic dynamic programming technique for the optimal operation of a reservoir, to control salinity in the reservoir and thereby also in releases. These procedures are to meet irrigation and municipal demands.. A stochastic dynamic programming technique for the optimal operation of a reservoir to control salinity in the reservoir and thereby also in the releases, and to meet irrigation and municipal demands is developed. The technique defines the optimal policy for releases to meet salinity and irrigation water supply requirements. The problem for which the approach was specifically developed is characterised by the presence of a strongly stratified, essentially two-layer, condition in a reservoir used to supply irrigation water. The two-layer condtion exists over the winter months when cold and heavy saline flows enter the reservoir and flow to the bottom of the reservoir. The two-layer condition continues until mixing of the reservoir occurs in early summer. While the reservoir is stratified, it is possible to flush the saline water out of the reservoir by low level intakes. This flushing reduces the overall salinity level in the reservoir when mixing occurs at end of winter, and thereby reduces the salinity of reservoir summer. However, removing the saline bottom layer also reduces the volume of water available for irrigation. Hence there are limitations on the amount that can be withdrawn to reduce the salinity. The technique is an approach to optimising the performance of the reservoir to meet irrigation demands, while minimising salt concentration in the irrigation water. Stochastic dynamic programming is used to reflect the uncertainty in the inflows while chance-constraints are reservoir beginning of the irrigation season. Three different probabilistic nature of the salt inflows to the reservoir: 1) salt load is directly related to the volume of inflow, 2) salt load is independent of the volume of the inflow, and 3) salt load is conditioned on the volume of inflow. The model is demonstrated by application to the Wellington Reservoir in Western Australia for the case in which the salt load is conditioned on the inflow. The results of the application of the model for a range of different combinations of maximum allowable saltconcentration and probability of exceeding that are compared to each other and to the release policy generated in an earlier simulation analysis undertaken to manage the salinity question.
Determining the area of convergence in Bloodstain Pattern Analysis: a probabilistic approach

description: A complete procedure for identifying the area of convergence of blood drops originated from a single static source is presented. Both for bloodstains lying on an horizontal and on a vertical plane a complete study is developed, based on error analysis and on an opportunely defined joint probability density for the orientation of the horizontal projections of the trajectories of the drops. The method generates a probabilistic map for the area of convergence, directly linking the angles of impact, and their uncertainties, to the projection on the ground of the point of origin. One of the objectives consists in providing a statistical definition of area of convergence, extending to this topic the mathematical accuracy of the calculation of the angle of impact in bloodstain pattern analysis (BPA).

description: We extend the data-driven method of Sparse Identification of Nonlinear Dynamics (SINDy) developed by Brunton et al, Proc. Natl. Acad. Sci USA 113 (2016) to the case of delay differential equations (DDEs). This is achieved in a bilevel optimization procedure by first applying SINDy for fixed delay and then subsequently optimizing the error of the reconstructed SINDy model over delay times. We test the SINDy-delay method on a noisy short data set from a toy delay differential equation and show excellent agreement. We then apply the method to experimental data of gene expressions in the bacterium {\it Pseudomonas aeruginosa} subject to the influence of zinc. The derived SINDy model suggests that the increase of zinc concentration mainly affects the time delay and not the strengths of the interactions between the different agents controlling the zinc export mechanism.

description: Project "theorises the engagement in an educational participatory action research project from the localised site of a nursing home for elderly people in Victoria".. This thesis presents the theoretical and practical development of a participatory action research project from the perspective of a localised site of action, a nursing home. The research design is inductively developed by participating staff of the nursing home, both nurses and non-nurses; the design and the range of participation are both unusual features of a nursing action research project in comparison with those conducted internationally to date. The role of the 'outsider' researcher, a nursing academic and a clinical nurse, was concurrently theorised and practically developed with the changing dynamics of this research project. A process of on-going theoretical and practical analysis of the research process and action in the nursing home was achieved through the use of 'critical incidents'. 'Critical incidents' arising during this participatory action research project have been theorised through a Foucauldian view of the history of institutions and the nature of modern power (Foucault, 1977). They gave rise to new understandings of the nature of nursing in a nursing home, and paid attention to issues of power, gender and ethics within this context. Social actions within the nursing home and the research process are explored, described and considered in the change process as being gendered in production. A focus on ethics, both of self ethics within the research process and of the development of situated, negotiated ethics in relation to others' daily actions in the nursing home, is explored and theorised through some of the critical incidents. Examples of the fourteen critical incidents include the exploration of aromatherapy which formed a way of interrupting the dominant production of medical interests in social actions of the nursing home, and the challenge to new staffing and catering decisions which interrupted managerial interests. A theoretical shift in this participatory action research project, and this thesis, is to see that undertaking new action rather than reflection may be the first step in liberatory processes and that these involve altering the boundaries of self.

description: In this work, we modify the standard flux tube simulation domain to include arbitrary ion gyroradius-scale variation in the radial profile of the safety factor. To determine how to appropriately include such a modification, we add a strong ion gyroradius-scale source (inspired by electron cyclotron current drive) to the Fokker-Planck equation, then perform a multi-scale analysis that distinguishes the fast electrons driven by the source from the slow bulk thermal electrons. This allows us to systematically derive the needed changes to the gyrokinetic model. We find new terms that adjust the ion and electron parallel streaming to be along the modified field lines. These terms have been successfully implemented in a gyrokinetic code (while retaining the typical Fourier representation), which enables flux tube studies of non-monotonic safety factor profiles and the associated profile shearing. As an illustrative example, we investigate tokamaks with positive versus negative triangularity plasma shaping and find that the importance of profile shearing is not significantly affected by the change in shape.

description: The nitrogen-vacancy color center in diamond is one of the most important systems in the fast-growing field of sensing. This color centers are used in both high-resolution and high-sensitivity sensors. However, techniques for quick and efficient formations of this color center are still in the development stage. In this paper, we present a study on the influence of the electron irradiation dose on the conversion of substitutional nitrogen into $\text{N}{\text{V}^{-}}$ centers. The study was done on diamonds that were highly enriched with nitrogen (~100 ppm), which on one hand should maximize the effect of irradiation, and on another be of interest for high-sensitivity magnetometers. The maximum achieved conversion efficiency was as high as ${37\pm 3.7}$, with no observed saturation on the electron dose even with the simplest annealing procedure. The measurements of the corresponding dephasing time made it possible to estimate for shot-noise limited sensitivity per unit volume of a stationary field sensor with such a diamond to be ${9\pm 1\times {{10}^{-14}}\text{T}}/{\sqrt{\text{Hz}\cdot \text{m}{\text{m}^{-3}}}}\;$.

description: In August of 2017, a new court called the North Lawndale Restorative Justice Community Court (NLRJCC) opened in North Lawndale, Chicago. Unlike traditional criminal courts, the NLRJCC is predicated on the theory of restorative justice, which is a philosophy for repairing harm that seeks to rehabilitate the offender while reconciling them to their victim and the community. Using a combination of participation, ethnography, stakeholder interviews, and document review, this thesis argues that the NLRJCC is challenging our country’s inequitable social order, and the criminal justice system that upholds it. As the NLRJCC is demonstrating, justice need not be what it has always been — if we have the courage and willingness to think differently.

description: Projects aims to provide school administrators and policy makers with the results of educational change - in this case the introduction of a vertical timetable and its impact on the school community, in particular the teachers.. This thesis presents an examination of the way in which an educational initiative, delivery of the curriculum using a vertical timetable, impinges upon the education community concerned, in particular the teachers. The research aims to provide school administrators and policy makers with insights into the impact of an educational change. The investigation was conducted over the period of 2 years in a group of schools where the vertical timetable was introduced. Teachers, administrators, students and parents/guardians participated in the study. The researcher adhered to a constructivist approach to the research and employed a case study method. Responses were gathered using questionnaires and a focus group interview. The study identified key issues for students and teachers. Analysis of these themes yielded several practical recommendations for administrators who plan to implement vertical timetabling.

description: Project models the reliability of an urban water distribution network.. Reliability is one of the fundamental considerations in the design of urban water distribution networks. The reliability of a network can be modelled by the probability of the connectedness of a stochastic graph. The enumeration of a set of cuts of the graph, and the calculation of the disjoint probability products of the cuts, are two fundamental steps in the network reliability assessment. An improved algorithm for the enumeration of all the minimal cutsets of a graph is presented. Based on this, a recursive algorithm for the enumeration of all Buzacott cuts (a particular set of ordered cuts) of a graph has been developed. The final algorithm presented in this thesis incorporates the enumeration of Buzacott cuts and the calculation of the disjoint probability products of the cuts to obtain the network reliability. As a result, it is tightly coupled, and very efficient. Experimental results show that this algorithm has a higher efficiency than other reported methods. The parallelism existing in the reliability assessment is investigated. The final algorithm has been implemented in a concurrent computer program. The effectiveness of parallel programming techniques in reducing the computing time required by the reliability assessment has also been discussed.

Transition from band insulator to Mott insulator and formation of local moment in half-filled ionic SU($N$) Hubbard model

description: We investigate the local moment formation in the half-filled SU($N$) Hubbard model under a staggered ionic potential. As the Hubbard $U$ increases, the charge fluctuations are suppressed and eventually frozen when $U$ is above a critical value $U_c$, marking the development of well-defined local moment with integer $m$ fermions on the A-sublattice and $(N-m)$ fermions on the B-sublattice, respectively. We obtain an analytical solution for $U_c$ for the paramagnetic ground state within the variational Gutzwiller approximation and renormalized mean field theory. For large $N$, $U_c$ is found to depend on $N$ linearly with fixed $m/N$, but sublinearly with fixed $m$. The local moment formation is accompanied by a peculiar phase transition from the band insulator to the Mott insulator, where the ionic potential and quasiparticle weight are renormalized to zero simultaneously. Inside the Mott phase, the low energy physics is described by the SU($N$) Heisenberg model with conjugate representations, which is widely studied in the literature.

description: We construct a class of supersymmetric vacua of type IIB string theory describing systems of three- and seven-branes non-perturbatively completed by brane instantons. The vacua are specified by a set of holomorphic functions defined over a complex plane up to non-trivial U-duality monodromies around the brane locations. In the simplest setting, the solutions can be seen as a generalization of F-theory elliptic fibrations, where the torus fiber is replaced by a genus two Riemann surface with periods encoding the information on the axio-dilaton, the warp factor and the NS-NS and R-R fluxes.

description: It is commonly assumed that the stochastic background of gravitational waves on cosmological scales follows an almost scale-independent power spectrum, as generically predicted by the inflationary paradigm. However, it is not inconceivable that the spectrum could have strongly scale-dependent features, generated, e.g., via transient dynamics of spectator axion-gauge fields during inflation. Using the temperature and polarisation maps from the \textit{Planck} and BICEP/Keck datasets, we search for such features, taking the example of a log-normal bump in the primordial tensor spectrum at CMB scales. We do not find any evidence for the existence of bump-like tensor features at present, but demonstrate that future CMB experiments such as LiteBIRD and CMB-S4 will greatly improve our prospects of determining the amplitude, location and width of such a bump. We also highlight the role of delensing in constraining these features at angular scales $\ell\gtrsim 100$.

description: The demand for fish meal in aquaculture is an expensive part of aquaculture operations and this has generated interest in alternate food sources and use of natural live food. Use of traditional live food such as microalgae and zooplankton in aquaculture is reviewed. The current taxonomy of the redclaw Cherax quadricarinatus (von Martens, 1868), silver perch Bidyanus bidyanus (Mitchell, 1838), and the oligochaetes; Aulophorus sp. (Schmarda, 1861), Branchiura sowerbyi (Beddard, 1892), Tubifex tubifex (Muller, 1774) and the terrestial worm Dendrodrilus rubidus (Savigny, 1826) was elucidated. Culture requirements for worm species and the nutritional and culture requirements for the aquaculture target species were determined as follows: The best substrate for mass production of Aulophorus was 100% cowdung, at a water temperature of 15°C. There was a significant correlation between oxygen concentration and reproduction in Aulophorus sp. with production levels of 3194.5 mg of T. tubifex per cm2 reached within 60 days and 4242.5 mg per cm2 of B. sowerbyi. Both were cultured in a mixture of 75% cowdung, 20% fine sand and 5% mud. An alternate substrate/food (ground peanut/shell, wheat pollard, rolled oats and lucerne pellets) was utilised for the mass propagation of T. tubifex and B. sowerbyi. Production of 2352 mg T. tubifex per cm2 and 2339.34 mg per cm2 of B. sowerbyi was obtained after 60 days. The population density was significantly influenced by substrate type, with highest population densities in the cowdung based substrate. Experimental culture of the terrestial worm D. rubidus was also carried out. Percentage increase in number and mean weight increase of the inoculated worms after a month was 532.2% and 0.50 g and an average of 2797 juveniles weighing 839.1 g was collected from each culture container after four weeks. Trials of oligochaete species as food for C. quadricarinatus juveniles, were conducted, single species and combinations of worm species being used. The nutritive values of T. tubifex and B. sowerbyi, for redclaw stocks from the Gregory, Mitchell, Gilbert, Flinders and Leichhardt river systems of North Queensland were compared with a commercial pellet (Aquafeed) as a reference diet and a lucerne pellet. The nutritive values of Aulophorus sp. and Dendrodrilus rubidus were compared with Aquafeed. Digestibility experiments were performed using Aulophorus sp. and B. sowerbyi.
The impacts of ultraviolet radiation feedback on galaxies during the epoch of reionization

description: We explore the impacts of ultraviolet (UV) radiation feedback on galaxies during the epoch of reionisation by cosmological simulations in which hydrodynamics and the transfer of the H and He ionising photons are consistently coupled. Moreover we take into account H_2 non-equilibrium chemistry, including photo-dissociation. The most striking feature of the simulations is a high spatial resolution for the radiative transfer (RT) calculation which enables us to start considering not only external UV feedback processes but also internal UV feedback processes in each galaxy. We find that the star formation is significantly suppressed due to the internal UV and supernova (SN) feedback. In low mass galaxies with M<10^9Msun, a large amount of gas is evacuated by photo-evaporation as previous studies have shown, which results in the suppression of star formation. Surprisingly, star formation in massive halos is also strongly suppressed despite the fact that these halos hardly lose any gas by photo-evaporation. The suppression of star formation in massive halos is mainly caused by following two factors; (i) small scale clumpy structures in the galaxies are smoothened by the internal feedback, (ii) although the dense gas in the galaxies is mostly neutral, the H_2 formation and cooling processes are disturbed by mild photo-heating. Photo-dissociating radiations actually suppress star formation, but the magnitude of the effect is not so large in massive galaxies. Even though our simulation volume is too small to be a representative patch of the Universe during reionisation, we find that our simulated star formation rate densities and HI fractions at z=6-7 are consistent with those found in observations.

description: Modern data analytics applications prefer to use column-storage formats due to their improved storage efficiency through encoding and compression. Parquet is the most popular file format for column data storage that provides several of these benefits out of the box. However, geospatial data is not readily supported by Parquet. This paper introduces Spatial Parquet, a Parquet extension that efficiently supports geospatial data. Spatial Parquet inherits all the advantages of Parquet for non-spatial data, such as rich data types, compression, and column/row filtering. Additionally, it adds three new features to accommodate geospatial data. First, it introduces a geospatial data type that can encode all standard spatial data types in a column format compatible with Parquet. Second, it adds a new lossless and efficient encoding method, termed FP-delta, that is customized to efficiently store geospatial coordinates stored in floating-point format. Third, it adds a light-weight spatial index that allows the reader to skip non-relevant parts of the file for increased read efficiency. Experiments on large-scale real data showed that SpatialParquet can reduce the data size by a factor of three, even without compression. Compression can further reduce the storage size. Additionally, Spatial Parquet can reduce the reading time by two orders of magnitude when the light-weight index is applied. This initial prototype can open new research directions to further improve geospatial data storage in column format.

description: We review the theoretical and experimental situation for long-lived heavy quarks, or bound states thereof, arising in simple extensions of the Standard Model. If these particles propagate large distances before their decay, they give rise to specific signatures requiring dedicated analysis methods. In particular, vector-like quarks with negligible couplings to the three known families could have eluded the past experimental searches. While most analyses assume prompt decays at the production vertex, novel heavy quarks might lead to signatures involving displaced vertices, new hadronic bound states, or decays happening outside of the detector acceptance. We perform reinterpretations of existing searches for short- and long-lived particles, and give suggestions on how to extend their reach to long-lived heavy quarks.

The history of policing is also discussed, from the early convict days to the methods employed by the Queensland Police Service.. This study explores how the residential and business sectors of the community in the southern Gold Coast area perceive the police service provided to them. The study also records the community level of satisfaction with that service. To provide a .context for theses community outcomes, contemporary policing issues in Australia are discussed, in particular how policing has developed from the early convict days to the current methods used by the Queensland Police Service to deliver its service. This study discusses such issues in policing as technology and the current concepts underlying police response times and police numbers and the impact this has on crime and community satisfaction levels. International concepts in crime prevention and community policing are explored and are highlighted by examples of community policing case studies conducted by the Queensland Police Service. Various studies relating to crime prevention are reviewed and the community fear of crime is discussed. Of particular interest is the expansion and theoretical considerations of situational crime prevention as relates to routine crime prevention activity and the role of guardians. The role of police as guardians for break and enter crime is of particular interest. The study concludes that a police response in this role is inadequate and alternative strategies must be implemented. Alternative strategies of guardianship could find the police implementing activities that empower the community with knowledge and resources to perform the role of guardians against break and enter crime themselves.

description: We consider a two-dimensional honeycomb lattice of metallic nanoparticles, each supporting a localized surface plasmon, and study the quantum properties of the collective plasmons resulting from the near field dipolar interaction between the nanoparticles. We analytically investigate the dispersion, the effective Hamiltonian and the eigenstates of the collective plasmons for an arbitrary orientation of the individual dipole moments. When the polarization points close to the normal to the plane the spectrum presents Dirac cones, similar to those present in the electronic band structure of graphene. We derive the effective Dirac Hamiltonian for the collective plasmons and show that the corresponding spinor eigenstates represent Dirac-like massless bosonic excitations that present similar effects to electrons in graphene, such as a non-trivial Berry phase and the absence of backscattering off smooth inhomogeneities. We further discuss how one can manipulate the Dirac points in the Brillouin zone and open a gap in the collective plasmon dispersion by modifying the polarization of the localized surface plasmons, paving the way for a fully tunable plasmonic analogue of graphene.

L’OHMi NUNAVIK tend à développer un cadre de recherche holistique et intégrateur faisant tomber les barrières entre disciplines d’une part, et types de savoirs (scientifiques / autochtones) d’autre part. Il vise ainsi à créer une structure de recherche innovante en Arctique par le prisme (i) des représentations arctiques des Inuits et des Qallunaat, (ii) les collaborations entre chercheurs, gestionnaires territoriaux et habitants. L’objectif de l’OHMi NUNAVIK porte sur l’acquisition de connaissances et de nouvelles manières de les produire afin d’identifier les impacts cumulatifs des programmes de développements économiques du Nunavik et des Plans Nord successifs du Québec depuis 2011, et des changements socio-environnementaux globaux sur cette aire d’étude. Au total, sept projets de recherche se déploient au sein de l’OHMi NUNAVIK ; quatre d’entre eux (Nuna, Kingaq, Niqiliriniq et Siqiniq) sont ici mobilisés pour illustrer le fonctionnement de l’OHMi NUNAVIK, les techniques d’observations utilisées, les collaborations produites.

description: Demonstrates the procedure and flexibility of using the information theory approach to evaluate the performance of water quality monitoring networks. Specific application of these are used in the evaluation of the Isaac River water quality monitoring network in Central Queensland.. Continued population growth, improved standards of living, and an increasing concern for the environment require careful management strategies to ensure the ecologically sustainable development and future availability of water resources. Water quality monitoring is an integral component of this management process. A water quality monitoring network is a monitoring system which provides management with the status of water quality conditions at a variety of locations and instances of time. While a range of significant challenges exist within the effective and efficient design of the monitoring system, one of the most critical of these challenges is the need for the selection of representative temporal and spatial sampling frequencies which neither replicate nor compromise the 'informativeness' and effectiveness of the monitoring. Recent research has employed information entropy concepts of transferred information and loss of information content to measure the representativeness and 'informativeness' of water quality monitoring networks. On the basis of a review of the principles and theory which underpin the concepts in their application to evaluation of performance, an improved methodology based on entropy theory was developed and applied to a typical Central Queensland water quality monitoring network. Success was particularly achieved in identifying the optimal selections of water quality variables and monitoring station locations. Other significant results from the analysis include the recognition of relationships between the transfer function and the criteria of transferred information, evidence of a 'priority order' for the removal of variables from a monitoring programme and a relationship between the co-variance matrix determinant and the class interval size which may alleviate the problem of calculating unstable joint entropies.

description: $CP$ violation of the decay $B^{\pm}\rightarrow π^{\pm}π^{+}π^{-}$ in the $f_{0}(500)-ρ(770)^{0}$ interfering region is analyzed. The forward-backward asymmetries (FBAs) and the corresponding $CP$ asymmetries FB-$CP$As are particularly investigated. To isolate the $CP$V caused by the interference of different partial wave more cleanly, we also introduce the direct-$CP$V-subtracted FB-$CP$A. Based on the LHCb data, we extract the FBAs, FB-$CP$As, direct-$CP$V-subtracted FB-$CP$A, as well as the regional $CP$As with invariant mass of the $π^{+}π^{-}$ pair in the range 0.2 GeV/$c^{2}<\sqrt{s_{\text{low}}}<1.8$ GeV/$c^{2}$. It is found that the (direct-$CP$V-subtracted) FB-$CP$As are quite large in the $f_{0}(500)-ρ(770)^{0}$ interfering region, which confirms that the interference of the intermediate resonances $f_{0}(500)$ and $ρ(770)^{0}$ plays an important role for the $CP$ violation of the three-body decay channel $B^{\pm}\rightarrow π^{\pm}π^{+}π^{-}$.

description: Generating power system states that have similar distribution and dependency to the historical ones is essential for the tasks of system planning and security assessment, especially when the historical data is insufficient. In this paper, we described a generative model for load profiles of industrial and commercial customers, based on the conditional variational autoencoder (CVAE) neural network architecture, which is challenging due to the highly variable nature of such profiles. Generated contextual load profiles were conditioned on the month of the year and typical power exchange with the grid. Moreover, the quality of generations was both visually and statistically evaluated. The experimental results demonstrate our proposed CVAE model can capture temporal features of historical load profiles and generate `realistic' data with satisfying univariate distributions and multivariate dependencies.

Coulomb drag between two graphene layers at different temperatures

description: We theoretically study the Coulomb drag in graphene when there is a temperature difference between the layers. Within the degenerate limit for equal layer densities, we find that this can lead to significant deviations from the usual quadratic temperature dependence of the drag resistivity. The exact behavior depends strongly on the phase space available for intraband scattering, and is not symmetrical when the temperatures of the layers are interchanged. In particular, when one layer is at a much higher temperature $T$ than the other, the drag resistivity behaves as $ρ_D\sim T/d^5$, where $d$ is the interlayer separation. The magnitude of the drag in this limit is always larger when the active layer is at the higher temperature.

description: SN2011ht has been described both as a true supernova and as an impostor. In this paper, we conclude that it does not match some basic expectations for a core-collapse event. We discuss SN2011ht's spectral evolution from a hot dense wind to a cool dense wind, followed by the post-plateau appearance of a faster low density wind during a rapid decline in luminosity. We identify a slow dense wind expanding at only 500--600 km/s, present throughout the eruption. A faster wind speed V ~ 900 km/s may be identified with a second phase of the outburst. There is no direct or significant evidence for any flow speed above 1000 km/s; the broad asymmetric wings of Balmer emission lines in the hot wind phase were due to Thomson scattering, not bulk motion. We estimate a mass loss rate of order 0.04 Msun/yr during the hot dense wind phase of the event. There is no evidence that the kinetic energy substantially exceeded the luminous energy, roughly 2 X 10^49 ergs; so the total energy was far less than a true SN. We suggest that SN2011ht was a giant eruption driven by super-Eddington radiation pressure, perhaps beginning about 6 months before the discovery. A strongly non-spherical SN might also account for the data, at the cost of more free parameters.

Spontaneous R-symmetry breaking from the renormalization group flow

description: We propose a mechanism of R-symmetry breaking in four-dimensional DSB models based on the RG properties of the coupling constants. By constraining the UV sector, we generate new hierarchies amongst the couplings that allow a spontaneously broken R-symmetry in models with pure chiral fields of R-charges R = 0 and R = 2 only. The result is obtained by a combination of one- and two-loop effects, both at the origin of field space and in the region dominated by leading log potentials.

description: We study the linear stability properties of spatially localized single- and multi-peak states generated in a subcritical Turing bifurcation in the Meinhardt model of branching. In one spatial dimension, these states are organized in a foliated snaking structure owing to peak-peak repulsion but are shown to be all linearly unstable, with the number of unstable modes increasing with the number of peaks present. Despite this, in two spatial dimensions direct numerical simulations reveal the presence of stable single- and multi-spot states whose properties depend on the repulsion from nearby spots as well as the shape of the domain and the boundary conditions imposed thereon. Front propagation is shown to trigger the growth of new spots while destabilizing others. The results indicate that multi-variable models may support new types of behavior that are absent from typical two-variable models.
