description: Networks of flexible filaments often involve regions of tight contact. Predictively understanding the equilibrium configurations of these systems is challenging due to intricate couplings between topology, geometry, large nonlinear deformations, and friction. Here, we perform an in-depth study of a simple yet canonical problem that captures the essence of contact between filaments. In the orthogonal clasp, two filaments are brought into contact, with each centerline lying in one of a pair of orthogonal planes. Our data from X-ray tomography (micro-CT) and mechanical testing experiments are in excellent agreement with the finite element method (FEM) simulations. Despite the apparent simplicity of the physical system, the data exhibits strikingly unintuitive behavior, even when the contact is frictionless. Specifically, we observe a curvilinear diamond-shaped ridge in the contact pressure field between the two filaments, sometimes with an inner gap. When a relative displacement is imposed between the filaments, friction is activated, and a highly asymmetric pressure field develops. These findings contrast to the classic capstan analysis of a single filament wrapped around a rigid body. Both the micro-CT and the FEM data indicate that the cross-sections of the filaments can deform significantly. Nonetheless, an idealized geometrical theory assuming undeformable tube cross-sections and neglecting elasticity rationalizes our observations qualitatively and highlights the central role of the small but finite tube radius of the filaments. We believe that our orthogonal clasp analysis provides a building block for future modeling efforts in frictional contact mechanics of more complex filamentary structures.

description: A model for the infrared emission of the high redshift ultraluminous infrared galaxy FSC 10214+4724 is presented. The model assumes three components of emission: a dusty torus viewed edge-on, clouds that are associated with the narrow-line region and a highly obscured starburst. It is demonstrated that the presence of clouds in the narrow-line region, with a covering factor of 17%, can explain why the mid-infrared spectrum of FSC 10214+4724 shows a silicate feature in emission despite the fact that its torus is viewed edge-on. It is also shown that the same model, but with the torus viewed face-on, predicts a spectrum with silicate emission features that is characteristic of the spectra of quasars recently observed with Spitzer.

Here we show a simple example of how the motion of a test particle under the influence of an inverse-quadratic potential in 1D is equivalent to that of another test particle moving freely in 2D Euclidean space and 3D Minkowskian space.

description: We propose an inclusive analysis of a stransverse mass (m_{T2}) using a hemisphere method for supersymmetry studies at the LHC . The hemisphere method is an algorithm to group collinear and high p_T particles and jets, assuming that there are two of such groups in a event. The m_{T2} is defined as a function of the unknown LSP mass, two hemisphere momenta, and missing transverse momentum. The kinematical end point of the m_{T2} distribution provides information on the squark and gluino masses. We perform a Monte Carlo simulation to study the inclusive m_{T2} distribution at the LHC. We show that the end point of the inclusive m_{T2} distribution has a cusp-like structure around the true LSP mass. The knowledge of the expected kinematical behavior near the end point for true events is important to establish the end point of the inclusive distribution. We find that the inclusive analysis is useful to obtain the information on the heaviest of the squark/gluino.

description: In a previous paper, we outlined a new Bayesian method for inferring the properties of extended gravitational lenses, given data in the form of resolved images. This method holds the most promise for optimally extracting information from the observed image, whilst providing reliable uncertainties in all parameters. Here, we apply the method to the well studied optical Einstein ring 0047-2808. Our results are in broad agreement with previous studies, showing that the density profile of the lensing galaxy is aligned within a few degrees of the light profile, and suggesting that the source galaxy (at redshift 3.6) is a binary system, although its size is only of order 1-2 kpc. We also find that the mass of the elliptical lensing galaxy enclosed by the image is (2.91$\pm$0.01)$\times10^{11}$ M$_{\sun}$. Our method is able to achieve improved resolution for the source reconstructions, although we also find that some of the uncertainties are greater than has been found in previous analyses, due to the inclusion of extra pixels and a more general lens model.

RNA genome packaging

description: All retroviruses selectively package two copies of their full-length, unspliced RNA genomes, both of which serve as templates for strand-transfer mediated recombination during reverse transcription. Genomes are selected for packaging as dimers, and RNA elements that promote dimerization and packaging are both located within the 5?-untranslated region (5?-UTR) of the viral RNA. Studies indicate that dimerization of the HIV-1 genome is mediated by a self-complementary GCGCGC sequence located within the loop of a pseudopalindromic hairpin (DIS), and that long range base pairing between residues of the 5?-Unique element (U5) and those overlapping the gag start codon (AUG) promotes dimerization by stabilizing a DIS loop-exposed conformation. The DIS hairpin of the closely related HIV-2 5?-UTR has also been proposed to contain a self-complementary dimer-promoting loop (GGUACC) and a long-range U5:AUG helix, but dimerization and mutagenesis studies have led to suggestions that U5:AUG formation inhibits, rather than promotes, HIV-2 RNA dimerization. To address facilitate comparative mechanistic studies and as a step toward determining the structural basis for HIV-2 genome selection, we have conducted quantitative RNA dimerization studies of native and mutant forms of the HIV-2 5?-UTR RNA using constructs and conditions similar to those employed previously for HIV-1. As observed previously, the HIV-2 5?-UTR RNA forms a much weaker dimer than that observed for HIV-1 5?-UTR. Unlike HIV-1 5?-UTR RNAs, HIV-2 RNAs are kinetically labile and dependent on Mg2+<2+< were only observed for deletion mutants and are attributed to RNA misfolding. Our findings indicate that U5:AUG formation promotes dimerization, and this may be a common feature of this class of hominine lentiviruses. Experiments also suggest that NC protein promotes the labile dimer formation. However, no significant difference is observed between U5:AUG enabled and disabled RNA constructs in the number of high affinity NC binding sites and the NC:RNA disassociation constant. In addition, we have identified the high affinity NC binding sites downstream of the DIS and found that the structure requirement for the exposure of the high affinity NC binding site (SL3) is a hairpin structure of AUG region.

description: Shortcut learning, in which models make use of easy-to-represent but unstable associations, is a major failure mode for robust machine learning. We study a flexible, causally-motivated approach to training robust predictors by discouraging the use of specific shortcuts, focusing on a common setting where a robust predictor could achieve optimal \emph{iid} generalization in principle, but is overshadowed by a shortcut predictor in practice. Our approach uses auxiliary labels, typically available at training time, to enforce conditional independences implied by the causal graph. We show both theoretically and empirically that causally-motivated regularization schemes (a) lead to more robust estimators that generalize well under distribution shift, and (b) have better finite sample efficiency compared to usual regularization schemes, even when no shortcut is present. Our analysis highlights important theoretical properties of training techniques commonly used in the causal inference, fairness, and disentanglement literatures.

description: The most conserved region of the HIV-1 genome, the 5’ - Untranslated Region (5’-UTR), is comprised of several structural elements that regulate various activities during the retroviral life cycle.  During the late phase of the HIV-1 replication cycle, assembling retroviruses selectively packaged two copies of their genomic RNA into viral particles. Recent phylogenetic analysis, secondary structure probing, and free-energy based secondary calculations suggest a novel long-range interaction between residues of the unique 5’ element and residues near the gag coding region. Utilizing Fluorescence Energy Resonance Transfer (FRET), Isothermal Titration Calorimetry (ITC), native polyacrylamide gel electrophoresis  (PAGE), and Nuclear Magnetic Resonance (NMR), we show that an 11-oligoribonucleotide spanning residues 105-115 of the 5’ - UTR (U5) binds to oligoribonucleotides containing the gag start codon (AUG), disrupts the pre-existing GNRA tetraloop, and forms a heterodimer (Kd = 0.47 +/- 0.16 μM) stabilized by Watson-Crick base pairs, indicating that the long-range U5:AUG interaction is feasible.  Recent studies suggest that the U5: AUG long-range interaction may play a significant role in controlling the monomer-dimer equilibrium of the HIV-1 5’ - UTR. Mutations in the 5’ - UTR that inhibit the proposed U5: AUG interaction, either by deletion of the AUG hairpin or stabilization of the AUG hairpin, strongly block dimerization. Furthermore, the addition of the AUG oligoribonucleotides in trans promotes dimerization by the GC-rich kissing loop in the DIS hairpin.  These finding imply that the DIS is sequestered in the monomeric RNA via a possible interaction with U5 and the formation of the U5: AUG long-range interaction exposes the DIS to promote dimerization.  Using mutagenesis and multi-dimensional NMR detection, we have devised an approach to directly probe for the novel U5: DIS interaction in the monomeric RNA.  Moreover, our studies provide preliminary evidence that the novel long-range interaction between U5 and DIS is possible.

description: A \emph{tree-partition} of a graph $G$ is a proper partition of its vertex set into `bags', such that identifying the vertices in each bag produces a forest. The \emph{tree-partition-width} of $G$ is the minimum number of vertices in a bag in a tree-partition of $G$. An anonymous referee of the paper by Ding and Oporowski [\emph{J. Graph Theory}, 1995] proved that every graph with tree-width $k\geq3$ and maximum degree $Δ\geq1$ has tree-partition-width at most $24kΔ$. We prove that this bound is within a constant factor of optimal. In particular, for all $k\geq3$ and for all sufficiently large $Δ$, we construct a graph with tree-width $k$, maximum degree $Δ$, and tree-partition-width at least $(\eighth-ε)kΔ$. Moreover, we slightly improve the upper bound to ${5/2}(k+1)({7/2}Δ-1)$ without the restriction that $k\geq3$.
Transport of toroidal magnetic field by the meridional flow at the base of the solar convection zone

description: In this paper we discuss the transport of toroidal magnetic field by a weak meridional flow at the base of the convection zone. We utilize the differential rotation and meridional flow model developed by Rempel and incorporate feedback of a purely toroidal magnetic field in two ways: directly through the Lorentz force (magnetic tension) and indirectly through quenching of the turbulent viscosity, which affects the parametrized turbulent angular momentum transport in the model. In the case of direct Lorentz force feedback we find that a meridional flow with an amplitude of around 2 m/s can transport a magnetic field with a strength of 20 to 30 kG. Quenching of turbulent viscosity leads to deflection of the meridional flow from the magnetized region and a significant reduction of the transport velocity if the magnetic field is above equipartition strength.

description: Combinatorial chemistry is a powerful tool in developing chemical libraries, which undergo high-throughput screening for potential drug leads, catalysts and materials. To address this demand, large combinatorial libraries of peptides, oligonucleotides, and other organic compounds have been developed based on solid phase synthesis (SPS). Polystyrene is the most popular SPS support for the majority of peptide synthesis while silica is preferred for oligonucleotides synthesis, but less frequently investigated. We have explored silica as a SPS support since it is inexpensive and has a higher coupling rate than polystyrene. Slica-bound 1-hydroxybenzotriazole (Si-HOBt) and polystyrene-bound 1-hydroxybenzotriazole (P-HOBt) based solid supports were prepared. Using these supports, a small combinatorial library of acetamides and benzamides were synthesized. Acetamides were obtained in higher yield irrespective of the solid support. Silica based synthesis had better yield of benzamides in comparison to polystyrene based synthesis. Besides this, Si-HOBt had retained a higher activity after five reuses. Therefore, Si-HOBt was chosen for further applications in analytical chemistry. Biogenic amines are precursors of carcinogenic N-nitroso compounds, and have been reported to cause liver cirrhosis, muscular dystrophy, diabetes, Alzheimer's disease and scombroid food poisoning. Hence, it is imperative that biogenic amines be monitored in food samples. Analysis of biogenic amines by gas chromatography-flame ionization detection (GC-FID) exhibits peak tailing and adsorption on to the columns. To overcome these problems, Si-HOBt based solid phase analytical derivatization (SPAD) was performed to convert the biogenic amines into a thermally stable, non-polar benzamides. Each analyte was individually tested for SPAD. Later, the mixture of biogenic amines were collectively derivatized and analyzed by GC-FID. SPAD was optimized with respect to solvent, time, quantity of the reagent and mode of derivatization. In addition, the SPAD was validated by the determination of biogenic amines in tuna and mackerel. A two week study of mackerel sample at 3, 21 and 37 ?C showed increasing peak areas and varying concentrations of tyramine and phenethylamine. The details of development, optimization and validation of SPAD will be discussed.

description: We introduce a simple technique for proving the transience of certain processes defined on the random tree $\mathcal{G}$ generated by a supercritical branching process. We prove the transience for once-reinforced random walks on $\mathcal{G}$, that is, a generalization of a result of Durrett, Kesten and Limic [Probab. Theory Related Fields 122 (2002) 567--592]. Moreover, we give a new proof for the transience of a family of biased random walks defined on $\mathcal{G}$. Other proofs of this fact can be found in [Ann. Probab. 16 (1988) 1229--1241] and [Ann. Probab. 18 (1990) 931--958] as part of more general results. A similar technique is applied to a vertex-reinforced jump process. A by-product of our result is that this process is transient on the 3-ary tree. Davis and Volkov [Probab. Theory Related Fields 128 (2004) 42--62] proved that a vertex-reinforced jump process defined on the $b$-ary tree is transient if $b\ge 4$ and recurrent if $b=1$. The case $b=2$ is still open.

description: We measure thermodynamic magnetization of a low-disordered, strongly correlated two-dimensional electron system in silicon. Pauli spin susceptibility is observed to grow critically at low electron densities - behavior that is characteristic of the existence of a phase transition. A new, parameter-free method is used to directly determine the spectrum characteristics (Lande g-factor and the cyclotron mass) when the Fermi level lies outside the spectral gaps and the inter-level interactions between quasiparticles are avoided. It turns out that, unlike in the Stoner scenario, the critical growth of the spin susceptibility originates from the dramatic enhancement of the effective mass, while the enhancement of the g-factor is weak and practically independent of the electron density.

description: Ultraviolet filters (UVFs) are used in a variety of personal care products, including sunscreens and cosmetics, to protect against ultraviolet (UV) radiation. Three of the most commonly employed UVFs are oxybenzone (OXY), octocrylene (OC), and octinoxate (OMC). While these compounds provide protection against harmful UV radiation, they also represent a unique human and ecological health risk. To address these concerns, ozone application to UVFs in water and wastewater matrices was carried out and transformation efficiency was calculated. Transformation efficiency varied with water/wastewater quality. For example, an applied ozone dose of 6 mol O3/mol OXY transformed approximately 62, 44, 23, and 13% of OXY in DI water, surface water, wastewater effluent, and raw wastewater, respectively. Second order rate constants were measured for UVF reaction with ozone; reactivity with ozone varied.  Second-order rate constants for OXY  kO3,app,OXY ranged from 3.65?102 to 1.68?106  M-1s-1; for OMC, kO3,OMC was 22(?2.14)?104 M-1s-1; and for OC, kO3,OC was 1.56 (?0.18) M-1s-1. The characteristic UV absorbance of solutions containing UVFs was measured as a function of wavelength, pH, and treatment level providing innovative insight into ozone attack mechanisms and identification of transformation products. Several transformation products were identified for ozonation of OXY, OMC, and OC and the corresponding structures represent similar environmental concerns as the parent UVFs.

description: We propose an analytical approach for computing the eigenspectrum and corresponding eigenstates of a hyperbolic double well potential of arbitrary height or width, which goes beyond the usual techniques applied to quasi-exactly solvable models. We map the time-independent Schrödinger equation onto the Heun confluent differential equation, which is solved by using an infinite power series. The coefficients of this series are polynomials in the quantisation parameter, whose roots correspond to the system's eigenenergies. This leads to a quantisation condition that allows us to determine a whole spectrum, instead of individual eigenenergies. This method is then employed to perform an in depth analysis of electronic wave-packet dynamics, with emphasis on intra-well tunneling and the interference-induced quantum bridges reported in a previous publication [H. Chomet et al, New J. Phys. 21, 123004 (2019)]. Considering initial wave packets of different widths and peak locations, we compute autocorrelation functions and Wigner quasiprobability distributions. Our results exhibit an excellent agreement with numerical computations, and allow us to disentangle the different eigenfrequencies that govern the phase-space dynamics.

description: Technological advances are creating exciting new opportunities that have the potential to move HPC well beyond traditional computational workloads. In this paper we focus on the potential for HPC to be instrumental in responding to disasters such as wildfires, hurricanes, extreme flooding, earthquakes, tsunamis, winter weather conditions, and accidents. Driven by the VESTEC EU funded H2020 project, our research looks to prove HPC as a tool not only capable of simulating disasters once they have happened, but also one which is able to operate in a responsive mode, supporting disaster response teams making urgent decisions in real-time. Whilst this has the potential to revolutionise disaster response, it requires the ability to drive HPC interactively, both from the user's perspective and also based upon the arrival of data. As such interactivity is a critical component in enabling HPC to be exploited in the role of supporting disaster response teams so that urgent decision makers can make the correct decision first time, every time.

description: 1-D Eulerian Vlasov-Maxwell simulations are presented which show kinetic enhancement of stimulated Raman backscatter (SRBS) due to electron trapping in regimes of heavy linear Landau damping. The conventional Raman Langmuir wave is transformed into a set of beam acoustic modes [L. Yin et al., Phys. Rev. E 73, 025401 (2006)]. For the first time, a low phase velocity electron acoustic wave (EAW) is seen developing from the self-consistent Raman physics. Backscatter of the pump laser off the EAW fluctuations is reported and referred to as electron acoustic Thomson scatter. This light is similar in wavelength to, although much lower in amplitude than, the reflected light between the pump and SRBS wavelengths observed in single hot spot experiments, and previously interpreted as stimulated electron acoustic scatter [D. S. Montgomery et al., Phys. Rev. Lett. 87, 155001 (2001)]. The EAW is strongest well below the phase-matched frequency for electron acoustic scatter, and therefore the EAW is not produced by it. The beating of different beam acoustic modes is proposed as the EAW excitation mechanism, and is called beam acoustic decay. Supporting evidence for this process, including bispectral analysis, is presented. The linear electrostatic modes, found by projecting the numerical distribution function onto a Gauss-Hermite basis, include beam acoustic modes (some of which are unstable even without parametric coupling to light waves) and a strongly-damped EAW similar to the observed one. This linear EAW results from non-Maxwellian features in the electron distribution, rather than nonlinearity due to electron trapping.

This formalism unifies the entanglement-assisted formalism and classical error correction, and includes encoding, error correction, and decoding steps such that the encoded quantum and classical information can be correctly recovered by the receiver. We formally define this kind of quantum code using both stabilizer and symplectic language, and derive the appropriate error-correcting conditions. We give several examples to demonstrate the construction of such codes.

Aboriginal and Torres Strait Islander Commission

description: ABSTRACT This paper is the first of two focusing on resource allocation policy and practice in the Aboriginal and Torres Strait Islander Commission (A TSIC). The current approach to the distribution of funds is examined here, while CAEPR Discussion Paper No. 42 examines the potential relevance and implications of fiscal equalisation for A TSIC's future funding policy and practice. A review of ATSIC's current financial structure and powers forms the context for a wider consideration of the financial relationships evolving between the organisation's structural elements. In the complex budgetary process, ATSIC's existing functionally-based program structure is linked to legally specified funding roles. The budgetary procedures and related program framework are critically examined. The role of regional councils and regional planning are discussed and the implications of financial tensions emerging between councils are raised. The emerging relationship between A TSIC's Board of Commissioners, administrative am1 and regional councils is posed as crucial, as is that between the newly-formed State Advisory Committees and councils . The paper considers the implications for A TSIC's current funding role of its representative regional structure, its program structure and emerging pressures towards decentralisation, arguing that ATSIC is in need of an integrated, holistic funding policy and procedures which link regional planning and service needs to national decisions about resource distribution.

description: We study the dynamical generation of masses for fundamental fermions in quenched quantum electrodynamics in the presence of weak magnetic fields using Schwinger-Dyson equations. Contrary to the case where the magnetic field is strong, in the weak field limit the coupling should exceed certain critical value in order for the generation of masses to take place, just as in the case where no magnetic field is present. The weak field limit is defined as eB << m(0)^2, where m(0) is the value of the dynamically generated mass in the absence of the field. We carry out a numerical analysis to study the magnetic field dependence of the mass function above critical coupling and show that in this regime the dynamically generated mass and the chiral condensate for the lowest Landau level increase proportionally to (eB)^2.

description: As a result of the Hund's coupling, the band structure of the conducting electrons in the skyrmion crystal (SkX) shares similar topological properties with that of graphene, such as its cone-like shape, nonzero band Chern number, edge states, and etc. In this work, we rigorously demonstrate that the Klein tunneling phenomena is also shared by these two. We use the Green's function technique and calculated the transmission probability of the electrons tunneling through an electrostatic barrier in the SkX expressed by the double exchange model. Numerical results of the SkX reproduced the Dirac model obtained by linear fitting the two-dimensional band structure of the SkX.
The road back from hell? : First Nations, self-government, and the universal goal of child protection in Canada
Creators: name: Harris, Sonia Ruth
Publisher: name: University of British Columbia
Year: 2009

description: The Canadian child welfare system has increasingly found itself under attack for its treatment of First Nations children. The charge is made that it imposes a colonial regime on First Nations families which negates the importance of their cultural identity, and devalues their cultural practices and traditions. Self-government is consistently advanced as the only appropriate response. The question this thesis addresses is whether too much faith is placed in self-government, without sufficient protections for children in the communities. The issue of First Nations child welfare is placed within the wider debates over the need for decolonisation in Canada. It is a premise of this thesis that First Nations hold an inherent right to self-government which demands respect for their sovereign authority in core areas such as child welfare. However, self-government is not a panacea for First Nations communities. The legacy of colonialism continues to manifest itself in the socioeconomic problems prevalent on many reserves/These problems pose a direct challenge to self-governing child welfare agencies and to the safety of the children in their care. This raises the dilemma of how to ensure the fundamental rights of First Nations children are effectively protected, whilst also respecting the 'sovereign' jurisdiction of First Nations communities. The attempts of non-native society to impose controls on First Nations governments, principally through the imposition of the Canadian Charter, are rejected on the basis they continue to perpetuate a colonial philosophy. However, adopting a theory of 'rejuvenated universalism,' and on the basis of a dialogue with three native controlled child welfare agencies in British Columbia, it is argued that agreement on fundamental standards of child welfare could be forged across native and non-native cultures. It is suggested these standards should be guaranteed in a Children's Charter binding all governments in Canada. A Children's Charter which has been developed through fully inclusive cross-cultural dialogue, and which consequently reflects the values of all the various cultures, would provide an essential mechanism for the external evaluation and review of child welfare agencies in Canada, whether native or non-native, according to their own freely accepted values and principles.

description: Exploration using borehole drilling is a key activity in determining the most appropriate locations for the petroleum industry to develop oil fields. However, estimating the amount of Oil In Place (OIP) relies on computing with a very significant number of geological models, which, due to the ever increasing capability to capture and refine data, is becoming infeasible. As such, data reduction techniques are required to reduce this set down to a smaller, yet still fully representative ensemble. In this paper we explore different approaches to identifying the key grouping of models, based on their most important features, and then using this information select a reduced set which we can be confident fully represent the overall model space. The result of this work is an approach which enables us to describe the entire state space using only 0.5\% of the models, along with a series of lessons learnt. The techniques that we describe are not only applicable to oil and gas exploration, but also more generally to the HPC community as we are forced to work with reduced data-sets due to the rapid increase in data collection capability.

description: The variational static formulation contributed in [International Journal of Engineering Science 143, 73-91 (2019)] is generalized in the present paper to model axial and flexural dynamic behaviors of elastic nano-beams by nonlocal strain and stress gradient approaches. Appropriate forms of non-standard boundary conditions are detected and properly prescribed. Equivalence between differential laws and integral convolutions is elucidated and invoked to analytically evaluate size-dependent axial and flexural fundamental frequencies of cantilever and fully-clamped beams which significantly characterize new-generation nano-actuators. The proposed methodology and ensuing results are tested by pertinent outcomes in literature. Advantageously, in comparison with available nonlocal gradient models, the developed formulation of elasticity leads to well-posed dynamic structural problems of nano-mechanics. Outcomes obtained by the well-established strain-driven and stress-driven nonlocal and gradient theories of Engineering Science are recovered under special ad hoc assumptions. The present study offers a simple and effective strategy to predict peculiar stiffening and softening dynamic responses of nano-scaled components of advanced technological devices, such as Nano-Electro-Mechanical-Systems (NEMS), and modern composite nano-structures.

description: The instability of mixing in the Kuramoto model of coupled phase oscillators is the key to understanding a range of spatiotemporal patterns, which feature prominently in collective dynamics of systems ranging from neuronal networks, to coupled lasers, to power grids. In this paper, we describe a codimension-2 bifurcation of mixing whose unfolding, in addition to the classical scenario of the onset of synchronization, also explains the formation of clusters and chimeras. We use a combination of linear stability analysis and Penrose diagrams to identify and analyze a variety of spatiotemporal patterns including stationary and traveling coherent clusters and twisted states, as well as their combinations with regions of incoherent behavior called chimera states. The linear stability analysis is used to estimate of the velocity distribution within these structures. Penrose diagrams, on the other hand, predict accurately the basins of their existence. Furthermore, we show that network topology can endow chimera states with nontrivial spatial organization. In particular, we present twisted chimera states, whose coherent regions are organized as stationary or traveling twisted states. The analytical results are illustrated with numerical bifurcation diagrams computed for the Kuramoto model with uni-, bi-, and tri-modal frequency distributions and all-to-all and nonlocal nearest-neighbor connectivity.
