Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

Associations of teachers of Japanese play an indispensable role in assisting not only teachers but also learners and impacting society by offering resources and opportunities for the growth of in-service teachers and pre-service teachers such as postgraduate students. Enhancing the quality of the resources and opportunities is expected to become effective when they know each other, learn from each other and work together. For this purpose, the Association of Japanese Language Teachers in Europe hosted a summit where the representatives of 22 European countries gathered to discuss the current and the future of Japanese language education in Europe. The aim of the current report is to present general but up-to-date information about the teachers, learners, institutions, associations, and features and challenges of each country. Furthermore, this report will illustrate the key discussions of the summit on the challenges and the possible actions for the viable future of Japanese language education in Europe. The Authors hope to contribute to creating the reference points for larger future studies on such associations while reflecting on the impact the summit possibly had.

Symmetry issues in shock ignited inertial fusion energy
Creators: name: Davie, Christopher
Publisher: name: Imperial College London
Year: 2014

description: Motivated by the shock ignition approach to improving the performance of inertial fusion targets, we make a series of studies of the stability of hydrodynamic shock waves. We first examine the behaviour of shocks moving through perturbations in background fluid in planar and 2D converging geometries, representing the ‘ignition’ shock moving through strongly perturbed material. To do this we follow the behaviour of finite amplitude perturbations on a 2D spherically converging shock wave, through convergence, reflection at its minimum radius and then into the expansion phase. We then extend this to pressure perturbations for converging shocks, representing asymmetries in the drive profile. These are then extended to 3D where we examine a uniquely 3D asymmetry, collapse and reflection of perturbed shock fronts without axial symmetry. We find that finite amplitude perturbations are transferred with little change through convergence into expansion, recovering their approximate ingoing form and find that shock fronts are robust against a range of asymmetries, specifically that the shock front is broadly stable against moderate perturbation, with only minor deviations from the symmetric behaviour. Even under fairly extreme, 3D perturbations in multiple parameters in convergent geometry the shock front remains robust and transfers with little change through convergence into expansion and recovers its approximate ingoing form. This stability of shock waves is at the root of the robustness of shock ignition and suggests this robustness is fully 3D.
Robustness of the $S$-deformation method for black hole stability analysis

description: The $S$-deformation method is a useful way to show the linear mode stability of a black hole when the perturbed field equation takes the form of the Schrödinger equation. While previous works where many explicit examples are studied suggest that this method works well, general discussion is not given yet explicitly. In this paper, we show the existence of a regular $S$-deformation when a black hole spacetime is stable under some reasonable assumptions. This $S$-deformation is constructed from a solution of a differential equation. We also show that the boundary condition for the differential equation which corresponds to a regular $S$-deformation has a one-parameter degree of freedom with a finite range. This is the reason why any fine-tune technique is not needed to find $S$-deformation numerically.

description: We present Keck LRIS spectroscopy along with NICMOS F110W (~J) and F160W (~H) images of the galaxy HDF4-473.0 (hereafter 4-473) in the Hubble Deep Field, with a detection of an emission line consistent with Ly-alpha at a redshift of z=5.60. Attention to this object as a high redshift galaxy was first drawn by Lanzetta, Yahil and Fernandez-Soto and appeared in their initial list of galaxies with redshifts estimated from the WFPC2 HDF photometry. It was selected by us for spectroscopic observation, along with others in the Hubble Deep Field, on the basis of the NICMOS F110W and F160W and WFPC2 photometry. For H_0 = 65 and q_0 = 0.125, use of simple evolutionary models along with the F814W (~I), F110W, and F160W magnitudes allow us to estimate the star formation rate (~13 M(solar)/yr). The colors suggest a reddening of E(B-V) ~ 0.06. The measured flux in the Ly-alpha line is approximately 1.0*10^(-17) ergs/cm/s and the restframe equivalent width, correcting for the absorption caused by intervening HI, is approximately 90AA. The galaxy is compact and regular, but resolved, with an observed FWHM of ~0.44". Simple evolutionary models can accurately reproduce the colors and these models predict the Ly-alpha flux to within a factor of 2. Using this object as a template shifted to higher redshifts, we calculate the magnitudes through the F814W and two NICMOS passbands for galaxies at redshifts 6 < z < 10.

description: Assuming the source of the anomalies observed recently in $b \to s$ data to be new physics, there is a priori no reason to believe that - in the effective field theory language - only one type of operator is responsible for the tensions. We thus perform for the first time a global fit where all the Wilson coefficients which can effectively receive new physics contributions are considered, allowing for lepton flavour universality breaking effects as well as contributions from chirality flipped and scalar and pseudoscalar operators, and find the SM pull taking into account all effective parameters. As a result of the full fit to all available $b \to s$ data including all relevant Wilson coefficients, we obtain a total pull of 4.1$σ$ with the SM hypothesis assuming 10% error for the power corrections. Moreover, we make a statistical comparison to find whether the most favoured explanation of the anomalies is new physics or underestimated hadronic effects using the most general parameterisation which is fully consistent with the analyticity structure of the amplitudes. This Wilks' test will be a very useful tool to analyse the forthcoming $B\to K^* μ^+ μ^-$ data. Because the significance of the observed tensions in the angular observables in $B \to K^* μ^+μ^-$ is presently dependent on the theory estimation of the hadronic contributions to these decays, we briefly discuss the various available approaches for taking into account the long-distance hadronic effects and examine how the different estimations of these contributions result in distinct significance of the new physics interpretation of the observed anomalies.

Regularity of McKean-Vlasov stochastic differential equations and applications
Creators: name: McMurray, Eamon Finnian Valentine
Publisher: name: Imperial College London
Year: 2015

description: In this thesis, we study time-inhomogeneous and McKean-Vlasov type stochastic differential equations (SDEs), along with related partial differential equations (PDEs). We are particularly interested in regularity estimates and their applications to numerical methods. In the first part of the thesis, we build on the work of Kusuoka \& Stroock to develop sharp estimates on the derivatives of solutions to time-inhomogeneous parabolic PDEs. The basis of these estimates is an integration by parts formula for derivatives of the solution under the UFG condition, which is weaker than the uniform Hoermander condition. This integration by parts formula is obtained using Malliavin Calculus. The formula allows us to extend the notion of classical solution to a framework where differentiability does not necessarily hold in all directions. As an application, we extend the error analysis for the cubature on Wiener space method to time-inhomogeneous stochastic differential equations. We then present two cubature on Wiener space algorithms for the numerical solution of McKean-Vlasov SDEs with smooth scalar interaction. The analysis involves the regularity estimates proved previously and takes place under a uniform strong Hoermander condition. Finally, we develop integration by parts formulas on Wiener space for solutions of SDEs with general McKean-Vlasov interaction and uniformly elliptic coefficients. These formulas hold both for derivatives with respect to a real variable and derivatives with respect to a measure in the sense of Lions. This allows us to develop estimates on the density of solutions of the McKean-Vlasov SDEs. We also prove the existence of a classical solution to a related PDE with irregular terminal condition.

description: We study the Singlet-Doublet dark matter model in the regime of feeble couplings, where the dark matter abundance is obtained via the freeze-in mechanism. As a consequence of the small couplings, the heavier particles in the model are long-lived with decay length at typical scales of collider experiments. We analyse the collider signatures of the model, characterised by displaced $h$ and $Z$ bosons plus missing momentum, employing current LHC searches for displaced vertices and missing energy to significantly constrain the parameter space of the model. We also take into account the cosmological bounds relevant for our light dark matter candidate arising from Lyman-$α$ forest constraints. Our analysis emphasises the interplay between displaced signatures at the LHC and cosmology for dark matter candidates whose relic abundance is obtained through the freeze-in mechanism.

description: We construct a new class of differential operators that naturally act on AdS harmonic functions. These are weight shifting operators that change the spin and dimension of AdS representations. Together with CFT weight shifting operators, the new operators obey crossing equations that relate distinct representations of the conformal group. We apply our findings to the computation of Witten diagrams, focusing on the particular case of cubic interactions and on massive, symmetric and traceless fields. In particular we show that tree level 4-point Witten diagrams with arbitrary spins, both in the external fields and in the exchanged field, can be reduced to the action of weight shifting operators on similar 4-point Witten diagrams where all fields are scalars. We also show how to obtain the conformal partial wave expansion of these diagrams using the new set of operators. In the case of 1-loop diagrams with cubic couplings we show how to reduce them to similar 1-loop diagrams with scalar fields except for a single external spinning field (which must be a scalar in the case of a two-point diagram). As a bonus, we provide new CFT and AdS weight shifting operators for mixed-symmetry tensors.

HOW FAR AWAY ARE GAMMA-RAY BURSTERS?
Creators: name: Paczynski, Bohdan
Publisher: name: arXiv
Year: 1995
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The positions of over 1000 gamma-ray bursts detected with the BATSE experiment on board of the Compton Gamma Ray Observatory are uniformly and randomly distributed in the sky, with no significant concentration to the galactic plane or to the galactic center. The strong gamma-ray bursts have an intensity distribution consistent with a number density independent of distance in Euclidean space. Weak gamma-ray bursts are relatively rare, indicating that either their number density is reduced at large distances or that the space in which they are distributed is non-Euclidean. In other words, we appear to be at the center of a spherical and bounded distribution of bursters. This is consistent with the distribution of all objects that are known to be at cosmological distances (like galaxies and quasars), but inconsistent with the distribution of any objects which are known to be in our galaxy (like stars and globular clusters). If the bursters are at cosmological distances then the weakest bursts should be redshifted, i.e. on average their durations should be longer and their spectra should be softer than the corresponding quantities for the strong bursts. There is some evidence for both effects in the BATSE data. At this time the cosmological distance scale is strongly favored over the galactic one, but is not proven. A definite proof (or dis-proof) could be provided with the results of a search for very weak bursts in the Andromeda galaxy (M31) with an instrument $ \sim 10 $ times more sensitive than BATSE. If the bursters are indeed at cosmological distances then they are the most luminous sources of electromagnetic radiation known in the universe. At this time we have no clue as to their nature, even though well over a hundred suggestions were published in the scientific journals. An experiment providing

Continuous versus Discontinuous Transitions in the $D$-Dimensional Generalized Kuramoto Model: Odd $D$ is Different

description: The Kuramoto model, originally proposed to model the dynamics of many interacting oscillators, has been used and generalized for a wide range of applications involving the collective behavior of large heterogeneous groups of dynamical units whose states are characterized by a scalar angle variable. One such application in which we are interested is the alignment of orientation vectors among members of a swarm. Despite being commonly used for this purpose, the Kuramoto model can only describe swarms in 2 dimensions, and hence the results obtained do not apply to the often relevant situation of swarms in 3 dimensions. Partly based on this motivation, as well as on relevance to the classical, mean-field, zero-temperature Heisenberg model with quenched site disorder, in this paper we study the Kuramoto model generalized to $D$ dimensions. We show that in the important case of 3 dimensions, as well as for any odd number of dimensions, the $D$-dimensional generalized Kuramoto model for heterogeneous units has dynamics that are remarkably different from the dynamics in 2 dimensions. In particular, for odd $D$ the transition to coherence occurs discontinuously as the inter-unit coupling constant $K$ is increased through zero, as opposed to the $D=2$ case (and, as we show, also the case of even $D$) for which the transition to coherence occurs continuously as $K$ increases through a positive critical value $K_c$. We also demonstrate the qualitative applicability of our results to related models constructed specifically to capture swarming and flocking dynamics in three dimensions.

Effect of precipitation and winds on sea surface elevation and storm surges
Creators: name: Wong, Benjamin
Publisher: name: Imperial College London
Year: 2015

description: Ocean circulation and storm surge models have neglected mass contributions from precipitation and can have a systematic bias in sea surface height (SSH). Here, a new rainfall scheme has been set up in the ocean circulation model Regional Ocean Modelling System (ROMS) to incorporate the effects of precipitation mass. When precipitation is added to the sea surface, it spreads out via surface gravity waves that increase in propagation speed with increasing water depth. Over several days, the increase in SSH due to the precipitation mass added created a geostrophic adjustment, generating clockwise-rotating geostrophic currents around the SSH increase. The transfer of momentum from precipitation to the sea surface, or rain stress, is investigated in ROMS. An error in the existing implementation of rain stress has been uncovered and corrected. The existing ROMS code generated an error in the direction of rain stress by up to 45 and systematically overestimated its magnitude by 41%. The SSH response to wind stress is examined. Positive and negative surges are generally generated by onshore and offshore winds respectively. While positive surges are widely studied, negative surges are less well understood. Negative surges are larger in magnitude and extend further across the coastline than positive surges. It is shown for the first time that the alongshore component of the wind stress is the main contributor to the asymmetrical surge response. Without this component, the ratio of negative to positive surge can decrease by more than half. This asymmetry also increases with increasing latitude and decreasing depth. In the case study of a real tropical cyclone, Monica, the effect of incorporating precipitation mass is compared with other processes affecting storm surge: surface wind, inverse barometer effect and rain stress. The maximum SSH response is 170.6 cm for the wind effect, 61.5 cm for the inverse barometer effect, 7.5 cm for the effect of rain stress and 6.4 cm for the effect of rain mass. Each process has been shown to have different spatial influences. The effect of rain mass has a strong remote influence compared to the inverse barometer effect and the effect of rain stress. This is particularly seen in semi-enclosed bays.

description: We report the discovery of two bright arcs in what turns out to be the brightest X--ray cluster in the ROSAT band ever observed, RXJ1347.5-1145. Its luminosity is $(6.2\pm0.6) \cdot10^{45}$erg s$^{-1}$ (in the range 0.1--2.4~keV). The arcs are most probably gravitationally lensed images of background galaxies. They were found serendipitously during our ongoing large--scale redshift survey of X--ray clusters detected by the ROSAT All Sky Survey. The arcs are almost opposite to each other with respect to the cluster centre, with a distance from it of about $35''$ ($=240 h^{-1}_{50}$ kpc), a radius that enables the probing of a rather large cluster volume. In this Letter we limit ourselves to the discussion of the general optical and X--ray features of this cluster and to the potential implications of the gravitational arcs. A more detailed discussion of the different mass estimates and of the cosmological implications for this exceptional object are left for future work based on more accurate optical and X--ray data, which are currently being collected.

Chemical proteomic profiling to investigate lipoprotein biogenesis in Clostridium difficile
Creators: name: Charlton, Thomas
Publisher: name: Imperial College London
Year: 2015

description: Bacterial lipoproteins feature an N-terminal Type II signal peptide, containing a lipobox motif which targets these proteins for post-translational lipidation. Following secretion, pre-prolipoprotein diacylglyceryl transferase (Lgt) catalyses the addition of an S-diacylglyceryl moiety to the lipobox cysteine thiol. The signal peptide sequence is then cleaved by a lipoprotein signal peptidase (Lsp), leaving the modified cysteine as the N-terminal residue of the mature Gram-positive lipoprotein. Lipoproteins are surface exposed and play an important role at the host-pathogen interface, as well as being implicated in nutrient uptake, sporulation and antibiotic resistance. Clostridium difficile is a Gram-positive, spore forming, obligate anaerobe which causes severe gastrointestinal disease in humans. Spores are the transmissible agent of C. difficile, with infection typically occurring via the faecal-oral route. Lipoproteins of C. difficile are known to function in nutrient uptake and adhesion and the lipoproteome is likely to be important in transmission and colonisation. Bacterial lipidation is difficult to study by traditional methods, however, metabolic tagging with bioothogonally-tagged lipid analogues has recently emerged as a powerful method to study lipidated proteins. This thesis describes the development and optimisation of metabolic tagging and quantitative chemical proteomics to investigate lipidation in C. difficile. The application of this approach to profile the lipoproteomes of 630 Δerm and the clinically relevant “hypervirulent” strain R20291 is described. This work includes the use of these probes, in combination with genetic and chemical inactivation of lgt, lspA and lspA2, to investigate lipoprotein biogenesis in C. difficile and to demonstrate the presence of two active Lsps. A combination of quantitative proteomics and phenotypic analysis has identified new functions for the C. difficile lipoproteome, including a role in the regulation of flagella and toxin production and in the initiation of sporulation.

description: We evaluate dust-corrected far ultraviolet (FUV) star formation rates (SFRs) for samples of star-forming galaxies at $z\sim0$ and $z\sim0.7$ and find significant differences between values obtained through corrections based on UV colour, from a hybrid mid-infrared (MIR) plus FUV relation, and from a radiative transfer based attenuation correction method. The performances of the attenuation correction methods are assessed by their ability to remove the dependency of the corrected SFR on inclination, as well as returning, on average, the expected population mean SFR. We find that combining MIR (rest-frame $\sim$13$μ$m) and FUV luminosities gives the most inclination independent SFRs and reduces the intrinsic SFR scatter out of the methods tested. However, applying the radiative transfer based method of Tuffs et al. gives corrections to the FUV SFR that are inclination independent and in agreement with the expected SFRs at both $z\sim0$ and $z\sim0.7$. SFR corrections based on the UV-slope perform worse than the other two methods tested. For our local sample, the UV-slope method works on average but does not remove inclination biases. At $z\sim$0.7 we find that the UV-slope correction used locally flattens the inclination dependence compared to the raw FUV measurements but was not sufficient to correct for the large attenuation observed at $z\sim$0.7.

description: Over a two year period (1995-1997), we have conducted a diffraction-limited imaging study at 2.2 microns of the inner 6"x6" of the Galaxy's central stellar cluster using the Keck 10-m telescope. The K band images obtained reveal a large population of faint stars. We use an unbiased approach for identifying and selecting stars to be included in this proper motion study, which results in a sample of 90 stars with brightness ranging from K=9-17 and velocities as large as 1,400+-100 km/sec. Compared to earlier work (Eckart et al. 1997; Genzel et al. 1997), the source confusion is reduced by a factor of 9, the number of stars with proper motion measurement in the central 25 arcsec^2 of our galaxy is doubled, and the accuracy of the velocity measurements in the central 1 arcsec^2 is improved by a factor of 4. The peaks of both the stellar surface density and the velocity dispersion are consistent with the position of the unusual radio source and blackhole candidate, Sgr A*, suggesting that Sgr A* is coincident (+-0."1) with the dynamical center of the Galaxy. As a function of distance from Sgr A*, the velocity dispersion displays a falloff well fit by Keplerian motion about a central dark mass of 2.6(+-0.2)x10^6 Mo confined to a volume of at most 10^-6 pc^3, consistent with earlier results. Although uncertainties in the measurements mathematically allow for the matter to be distributed over this volume as a cluster, no realistic cluster is physically tenable. Thus, independent of the presence of Sgr A*, the large inferred central density of at least 10^12 Mo/pc^3, which exceeds the volume-averaged mass densities found at the center of any other galaxy, leads us to the conclusion that our Galaxy harbors a massive central black hole.

description: We compare GGA+U calculations with available experimental data and analyze the origin of magnetic anisotropies in MnF$_2$, FeF$_2$, CoF$_2$, and NiF$_2$. We confirm that the magnetic anisotropy of MnF$_2$ stems almost completely from the dipolar interaction, while magnetocrystalline anisotropy energy plays a dominant role in the other three compounds, and discuss how it depends on the details of band structure. The latter is critically compared to available optical measurements. The case of CoF$_2$, where magnetocrystalline anisotropy energy strongly depends on $U$, is put into contrast with FeF$_2$ where theoretical predictions of magnetic anisotropies are nearly quantitative.

The organizational health of healthcare organisations: the concept and its measure
Creators: name: Nicolay, Christopher Robert
Publisher: name: Imperial College London

description: The concept of organisational health originates from fields as diverse as psychology, management, education and occupational health and stems back to the 1950s with the publication ‘The Organisation: What makes it healthy?’. One definition states, ‘organisational health blends the pursuit of individual wellness with organisational effectiveness (that can be optimised with contemporary business improvement initiatives such as Lean and Six Sigma) to yield a strategy for economic resilience’. In fields outside of healthcare e.g. business and education, correlations have been shown between organisational health and organisational performance (outcome measures), but is the same true in healthcare? At a time of financial difficulty within the NHS, and also with the need for improving patient outcomes, in wake of The Mid Staffordshire NHS Foundation Trust Public Inquiry for example, organisational health could become increasingly important in our hospitals. The methodologies used include systematic review, qualitative interview analysis, questionnaire development, and exploratory and confirmatory factor analyses (EFA & CFA) for questionnaire validation and data collection. This thesis begins with a systematic review of the organisational health literature followed by a qualitative interview study to establish the elements of organisational health for acute NHS Trusts in England. It then describes how, from this data, a pilot questionnaire was developed to measure organisational health and then exploratory factor analysis followed by confirmatory factor analysis techniques were used to create a reliable validated organisational health questionnaire containing 112-items across 8 sections. The next study describes the use of this questionnaire by almost 10,000 NHS staff at 29 acute Trusts in England to measure organisational health. The final study correlates these organisational health scores with hospital outcome measures, revealing that the healthiest organisations have improved outcomes for their patients, including a significantly lower mortality rate.

description: We address the problem of deriving, from the observed projected metallicity gradients, the intrinsic metallicity distribution of elliptical galaxies as a function of their integrals of motion. The method is illustrated by an application to anisotropic spherical Hernquist models. We also compare the derived metallicity distribution with those expected from two very simple models of galaxy formation and find that the more dissipative scheme agrees better with the typical metallicity distribution of ellipticals.

description: Bouchet et al. (1992) showed that in an open or closed Universe with only pressureless matter, gravitational instability from Gaussian initial conditions induces a normalized skewness, $S_3 \equiv \VEV{δ^3} \VEV{δ^2}^{-2}$, that has only a very weak dependence on the nonrelativistic-matter density. Here we generalize this result to a plethora of models with various contributions to the total energy density, including nonrelativistic matter, a cosmological constant, and other forms of missing energy. Our numerical results show that the skewness (and bispectrum) depend only very weakly ($\lesssim 2%$) on the expansion history. Thus, the skewness and bispectrum provide a robust test of gravitational instability from Gaussian initial conditions, independent of the underlying cosmological model.

description: Galaxy redshift surveys provide a distorted picture of the universe due to the non-Hubble component of galaxy motions. By measuring such distortions in the linear regime one can constrain the quantity $β= Ω^{0.6}/b$ where $Ω$ is the cosmological density parameter and $b$ is the (linear) bias factor for optically-selected galaxies. In this paper we apply two techniques for estimating $β$ from the Stromlo-APM redshift survey --- (1) measuring the anisotropy of the redshift space correlation function in spherical harmonics and (2) comparing the amplitude of the direction-averaged redshift space correlation function to the real space correlation function. We test the validity of these techniques, particularly whether the assumption of linear theory is justified, using two sets of large $N$-body simulations. We find that the first technique is affected by non-linearities on scales up to $\sim 30 \hMpc$. The second technique is less sensitive to non-linear effects and so is more useful for existing redshift surveys. The Stromlo-APM survey data favours a low value for $β$, with $β\simlt 0.6$. A bias parameter $b \approx 2$ is thus required if $Ω\equiv 1$. However, higher-order correlations measured from the APM galaxy survey (Gaztañaga and Frieman 1994) indicate a low value for the bias parameter $b \approx 1$, requiring that $Ω\simlt 0.5$. We also measure the relative bias for samples of galaxies of various luminosity and morphological type and find that low-luminosity galaxies are roughly three times less biased than $L^*$ galaxies. For the galaxy population as a whole, we measure a real space variance of galaxy counts in $8 \hMpc$ spheres of $(σ^2_8)_g = 0.89 \pm 0.05$.

description: We consider transverse-momentum resummation for top-quark pair production in hadron collisions. At small transverse momenta of the top-quark pair, the logarithmically-enhanced QCD contributions are resummed to all orders up to next-to-leading logarithmic accuracy. At intermediate and large values of transverse momenta, the resummation is consistently combined with the complete result at fixed perturbative order. We present numerical results for the transverse-momentum distribution of top-quark pairs at LHC energies. We perform a detailed study of the scale dependence of the results to estimate their perturbative uncertainty. We comment on the comparison with ATLAS and CMS data.

description: We use a free-energy minimization approach to describe the secular and dynamical instabilities as well as the bifurcations along equilibrium sequences of rotating, self-gravitating fluid systems. Our approach is fully nonlinear and stems from the Landau-Ginzburg theory of phase transitions. Here we examine higher than 2nd-harmonic disturbances applied to Maclaurin spheroids, the corresponding bifurcating sequences, and their relation to nonlinear fission processes. The triangle and ammonite sequences bifurcate from the two 3rd-harmonic neutral points on the Maclaurin sequence while the square and one-ring sequences bifurcate from two of the three known 4th harmonic neutral points. In the other three cases, secular instability does not set in at the corresponding bifurcation points because the sequences stand and terminate at higher energies relative to the Maclaurin sequence. There is no known bifurcating sequence at the point of 3rd-harmonic dynamical instability. Our nonlinear approach easily identifies resonances between the Maclaurin sequence and various multi-fluid-body sequences that cannot be detected by linear stability analyses. Resonances appear as first-order phase transitions at points where the energies of the two sequences are nearly equal but the lower energy state belongs to one of the multi-fluid-body sequences.
