description: A general scheme for axion electrodynamics is given, in which a surrounding medium of constant permittivity and permeability is assumed. Then, as an application we give simple numerical estimates for the electromagnetic current density produced by the electrically neutral time-dependent axions $a=a(t)$ in a strong magnetic field. As is known, the assumption $a=a(t)$ is common under astrophysical conditions. In the third part of the paper, we consider the implications by assuming instead an axion amplitude $a(z)$ depending on one coordinate $z$ only. If such an axion field is contained within two large metal plates one obtains an axion-generated splitting of the eigenmodes for the dispersion relation. These modes yield equal, though opposite, contributions to the pressure on the plates. We calculate the magnitude of the splitting effect, in a simple one-dimensional model.

INVOLVEMENT OF RIBOSOMAL PROTEINS IN RIBOSOME BIOGENESIS, CELL CYCLE PROGRESSION, AND BUDDING PATTERNS IN SACCHAROMYCES CEREVISIAE.

description: Ribosome biogenesis and cell cycle are coordinated processes (Du and Stillman, 2001 Bernstein and Baserga, 2004; Fatica and Tollervey, 2002; Li et al., 2009; Strezoska et al., 2002). Mutations in genes encoding factors that are involved in ribosome biogenesis cause defects in ribosomal RNA processing as well as cell cycle arrest. Recent studies with mammalian cell lines have shown that ribosome biogenesis is also linked to tumorgenesis, that is mutation or depletion of ribosomal factors, leads to cancer cell proliferation (Montanaro et al., 2008). The yeast Saccharomyces cerevisiae is a useful model organism for understanding the connections between ribosome biogenesis and cell cycle control. Only a handful of studies have been done and these have mainly focused on different transacting factors involved in ribosome biogenesis; few studies have focused on the roles of r-proteins themselves in linking cell cycle progression and rRNA processing. I wanted to investigate what roles these r-proteins may have in the progression of the cell cycle. My interest in this area was spurred by previous findings in our lab showing that depleting ribosomal protein RpL4 of S. cerevisiae results in defects in both rRNA processing and cell cycle- with accumulation of di- and tri-budded cells.  I analyzed strains constructed by Philip Milkereit's and John Woolford's labs in which the gene(s) for a given ribosomal protein were knocked out of the chromosome and a gene for that particular r-protein was placed under a galactose promoter (Pgal) either in the chromosome or a plasmid. In total, I analyzed constructs for twenty-nine 60S r-protein genes and twenty-seven 40S r-protein genes. To examine effects on the cell cycle of repression of the Pgal controlled gene, cells, were shifted to glucose medium, and the cultures were examined by flow cytometric analysis and sorting. Cells were also analyzed microscopically to look for abnormal cell morphology. I observed that depletion of r-proteins yields a variety of defects in DNA content and cell morphology, depending on which protein was repressed.  Depletion of RpL17 led to cells forming chains of varying lengths. I characterized this defect in more detail, analyzing, for example, spindle formation, chromosome segregation, and other cytological markers of the cell cycle. Ribosomal RNA processing and ribosome biogenesis for RpL17 were studied by Northern blots, sucrose gradients, pulse-chase analysis with radioactive uracil, and primer extension. These results showed that depletion of RpL17 leads to a defect in 27S processing and degradation of pre-existing ribosomes. My findings indicate that RpL17 plays a role in cell cycle progression, bud site-selection, ribosome biogenesis, and ribophagy, indicating a possibility that these pathways may be interconnected.

description: Quantum certainty mechanics is a theory for measuring the position and momentum of a particle. Mathematically proven certainty principle from uncertainty principle, which is basically one of the most important formulas of quantum certainty mechanics theory. The principle of uncertainty can be proved by the principle of certainty and why uncertainty comes can also be proved. The principle of certainty can be proved from the theory of relativity and in the uncertainty principle equation, the principle of certainty can be proved by fulfilling the conditions of the principle of uncertainty by multiplying the uncertain constant with the certain values ​​of momentum-position and energy-time. The principle of certainty proves that the calculation of θ ≥π/2 between the particle and the wave involved in the particle leads to uncertainty. But calculating with θ=0 does not bring uncertainty. Again, if the total energy E of the particle is measured accurately in the laboratory, the momentum and position can be measured with certainty. Quantum certainty mechanics has been established by combining Newtonian mechanics, relativity theory and quantum mechanics. Quantum entanglement can be explained by protecting the conservation law of energy.

description: Recent low-temperature scanning tunnelling spectroscopy experiments on the surface of BSCCO-2212 have revealed a strong positive correlation between the position of localized resonances at -960 meV identified with interstitial oxygen dopants and the size of the local spectral gap. We review efforts to understand these correlations within a model where the dopants modulate the pair interaction on an atomic scale. We provide further evidence for this model by comparing the correlations between the dopants and the local density of states with experimental results.

description: In the search for life in the cosmos, NASA's Transiting Exoplanet Survey Satellite (TESS) mission has already monitored about 74% of the sky for transiting extrasolar planets, including potentially habitable worlds. However, TESS only observed a fraction of the stars long enough to be able to find planets like Earth. We use the primary mission data - the first two years of observations - and identify 4,239 stars within 210pc that TESS observed long enough to see 3 transits of an exoplanet that receives similar irradiation to Earth: 738 of these stars are located within 30pc. We provide reliable stellar parameters from the TESS Input Catalog that incorporates Gaia DR2 and also calculate the transit depth and radial velocity semi-amplitude for an Earth-analog planet. Of the 4,239 stars in the Revised TESS HZ Catalog, 9 are known exoplanet hosts - GJ 1061, GJ 1132, GJ 3512, GJ 685, Kepler-42, LHS 1815, L98-59, RR Cae, TOI 700 - around which TESS could identify additional Earth-like planetary companions. 37 additional stars host yet unconfirmed TESS Objects of Interest: three of these orbit in the habitable zone - TOI 203, TOI 715, and TOI 2298. For a subset of 614 of the 4,239 stars, TESS has observed the star long enough to be able to observe planets throughout the full temperate, habitable zone out to the equivalent of Mars' orbit. Thus, the Revised TESS Habitable Zone Catalog provides a tool for observers to prioritize stars for follow-up observation to discover life in the cosmos. These stars are the best path towards the discovery of habitable planets using the TESS mission data.

Measuring Power Distribution System Resistance Variations for Application to Design for Manufacturability and Physical Unclonable Functions

Year: 2008
Subjects: Engineering, Electronics and Electrical (0544)

description: Metal resistance variations in back-end-of-line processes can be significant, particularly  during process bring-up. In this thesis, I propose a simple method to measure resistance variations in the Power Distribution System (PDS) of an IC, and describe how these  measurements can be applied to a Physical Unclonable Function (PUF). Our technique exploits the PDS, which is an existing distributed resource in all ICs, and provides a means of characterizing metal resistance in the context of an actual circuit design. By applying a sequence of tests using small on-chip support circuits attached to the PDS, the resistance of components of the PDS can be obtained from the solution to a set of simultaneous equations.  The results from hardware experiments involving two sets of test chips fabricated  in an IBM 65nm technology show significant changes in the resistance variation of some  components of the PDS as the process evolved.  This process variation data can be applied to hardware security by forming a PUF from  the various resistance components of the PDS.We demonstrate that this PUF signature can then be used to uniquely identify each IC, even in the more evolved set of test chips. Based on a population of 24 ICs, we have determined that the PUF is capable of distinguishing all but 47 out of 10,000 ICs. The signature may require only 46 bytes per IC.

description: From observations collected with the ESPaDOnS and NARVAL spectropolarimeters, we report the detection of Zeeman signatures on the classical T Tauri star BP Tau. Circular polarisation signatures in photospheric lines and in narrow emission lines tracing magnetospheric accretion are monitored throughout most of the rotation cycle of BP Tau at two different epochs in 2006. We observe that rotational modulation dominates the temporal variations of both unpolarised and circularly polarised spectral proxies tracing the photosphere and the footpoints of accretion funnels. From the complete data sets at each epoch, we reconstruct the large-scale magnetic topology and the location of accretion spots at the surface of BP Tau using tomographic imaging. We find that the field of BP Tau involves a 1.2 kG dipole and 1.6 kG octupole, both slightly tilted with respect to the rotation axis. Accretion spots coincide with the two main magnetic poles at high latitudes and overlap with dark photospheric spots; they cover about 2% of the stellar surface. The strong mainly-axisymmetric poloidal field of BP Tau is very reminiscent of magnetic topologies of fully-convective dwarfs. It suggests that magnetic fields of fully-convective cTTSs such as BP Tau are likely not fossil remants, but rather result from vigorous dynamo action operating within the bulk of their convective zones. Preliminary modelling suggests that the magnetosphere of BP Tau extends to distances of at least 4 R* to ensure that accretion spots are located at high latitudes, and is not blown open close to the surface by a putative stellar wind. It apparently succeeds in coupling to the accretion disc as far out as the corotation radius, and could possibly explain the slow rotation of BP Tau.

description: Linear Spectral Unmixing (LSU) has been widely used in remote sensing community. By considering Magnetic Resonance (MR) images as multispectral images, LSU can be also applied to MR image analysis. This thesis investigates issues in spectral classification for MR images using LSU approaches. Due to a limited number of MR images acquired by MR sequences, the ability of the LSU cannot be fully explored and utilized. In order to mitigate this dilemma, two approaches are developed to address this issue. One is Band Expansion Process (BEP) to expand an original set of MR images to an augmented set of multispectral images by including additional spectral band images that can be generated from the original MR images using a set of nonlinear functions. In this case, the LSU will have sufficient spectral bands to accommodate signal sources to be unmixed. The other is Kernel-based Principal Components Analysis (KPCA) to expand the original data space to a higher dimensional feature space in which the LSU can perform more effectively. In order to demonstrate the utility of the LSU in MR image analysis, two sets of MR images, synthetic MR images available on website and real MR images, are used for experiments. Experimental results show that the LSU can be a very effective technique in quantifying MR substances to calculate their partial volumes for further MR image analysis.

description: In our previous work of Ref. [5] we studied the stability of the RS2-model with a nonminimally coupled bulk scalar field $ϕ$, and we found that in appropriate regions of $ξ$ the standard RS2-vacuum becomes unstable. The question that arises is whether there exist other new static stable solutions where the system can relax. In this work, by solving numerically the Einstein equations with the appropriate boundary conditions on the brane, we find that depending on the value of the nonminimal coupling $ξ$, this model possesses three classes of new static solutions with different characteristics. We also examine what happens when the fine tuning of the RS2-model is violated, and we obtain that these three classes of solutions are preserved in appropriate regions of the parameter space of the problem. The stability properties and possible physical implications of these new solutions are discussed in the main part of this paper. Especially in the case where $ξ=ξ_c$ ($ξ_c$ is the five dimensional conformal coupling) and the fine tuning is violated, we obtain a physically interesting static stable solution.

Deterrents to participation in diabetes education : perspectives of elderly Sikh Indo-Canadians
Creators: name: Sanghera, Rema Rajeeta
Publisher: name: University of British Columbia
Year: 2009

description: Diabetes is a chronic disease which affects approximately 5% of all Canadians and contributes to considerable health care costs. At present diabetes can be controlled but not cured. Increased recognition that the provision of diabetes education is essential in diabetes management has led to the development of education programs in many Canadian hospitals. However, participation surveys done in the United States indicate that only 12 to 35% of individuals with diabetes receive education through formal programs. This study seeks to identify factors deterring participation of elderly Sikh Indo-Canadians with NIDDM in education programs. In depth interviews were conducted with the research participants. The Adapted Chain of Response Model was used as the framework to develop questions for the interview guide and to collect, organize and analyze the data. Deterrents identified in previous studies and supported by this study include: older age, low self-confidence, questioning the worth of the program, being on oral medications versus insulin, having one's own ways of self-care, having a family doctor for treating diabetes, financial concerns, time constraints and transportation problems, and an underestimation of the seriousness of NIDDM by doctors. Deterrents unique to the study include: viewing self as healthy, desiring anonymity, reliance on religion, not valuing non-doctors, lacking familial support, perceiving health professionals as lacking cultural sensitivity, lacking awareness of program purpose and existence, and not being referred at time of diagnosis. Family doctors not valuing diabetes education and/or services of health professionals and not encouraging individuals to attend were also identified as deterrents. This study makes recommendations for practice and research which may be useful to diabetes educators, health care organizations and researchers in assisting them to fully understand and address challenges involved in making diabetes education a reality for a greater number of individuals with diabetes.

For this purpose we calculate the overlap of the mean-field Slater determinant with one containg pure Gaussians and perfect spin and isospin symmetry, optimizing the overlap by varying the alpha-particle positions and radii. In some cases a coherent sum over different configurations is also employed. We find quite large overlaps for some of the lighter systems that diminish for nuclei above Ne20 but again strong clustering in Ar36.

description: Elastic geodesic grids (EGG) are lightweight structures that can be easily deployed to approximate designer provided free-form surfaces. In the initial configuration the grids are perfectly flat, during deployment, though, curvature is induced to the structure, as grid elements bend and twist. Their layout is found geometrically, it is based on networks of geodesic curves on free-form design-surfaces. Generating a layout with this approach encodes an elasto-kinematic mechanism to the grid that creates the curved shape during deployment. In the final state the grid can be fixed to supports and serve for all kinds of purposes like free-form sub-structures, paneling, sun and rain protectors, pavilions, etc. However, so far these structures have only been investigated using small-scale desktop models. We investigate the scalability of such structures, presenting a medium sized model. It was designed by an architecture student without expert knowledge on elastic structures or differential geometry, just using the elastic geodesic grids design-pipeline. We further present a fabrication-process for EGG-models. They can be built quickly and with a small budget.

description: Despite successful education campaigns through the media, and the evolution of numerous treatments, ischaemic heart disease remains one of the biggest causes of morbidity and mortality in the Western World. Development of anti-arrhythmic drugs was largely halted in the late'80s and early '90s prior to the discovery of the myocardial persistent sodium current and in particular, prior to the discovery that the myocardial persistent sodium current is considerably enhanced by hypoxia. We hypothesised that persistent sodium current blockade may reduce the extent of myocardial damage and the incidence of arrhythmias, and in particular lethal arrhythmias, arising from ischaemic heart disease. METHODS: Patch clamping and fluorescence studies were performed to determine whether Riluzole blocked persistent sodium currents and calcium influx during hypoxia and reperfusion. Isolated heart studies were performed to determine whether Riluzole provided cardioprotection during ischaemia-reperfusion. Whole animal studies were performed to determine whether Riluzole reduced the extent of myocardial damage and the incidence of arrhythmias from ischaemia and/or from ischaemia-reperfusion. Whole animal studies were also performed to determine whether Riluzole reduced the extent of skeletal muscle damage from ischaemia and/or reperfusion. RESULTS: Riluzole was found to: block persistent but not transient sodium currents, inhibit calcium influx and enhance cell shortening, enhance recovery from global ischaemia, not affect monophasic action potentials, reduce the extent of ischaemic myocardial damage, reduce the extent of reperfusion myocardial damage, halve the number of animals developing sustained arrhythmias, not alter the phases of arrhythmias, reduce the incidence of all types of ischaemic Phase 2 arrhythmias, reduce the incidence of all types ofreperfusion Phase 2 arrhythmias, be a more selective persistent sodium current blocker and better antiarrhythmic and anti-ischaemic than Lidocaine, not possess class 1 antiarrhythmic properties, be positively inotropic, be positively lusitropic, reduce the extent of ischaemic damage in skeletal muscle, reduce the extent of reperfusion damage in skeletal muscle, and most importantly, be safe for administration at doses similar to those used for treating Amyotrophic Lateral Sclerosis. CONCLUSIONS: Riluzole appears to be extremely potent for treating ischaemic heart disease and for providing cardioprotection in the current setting where there are no other satisfactory drugs. Riluzole also appears to have potential in treating skeletal muscle ischaemic and reperfusion.

description: This paper describes the software DRAGraces (Data Reduction and Analysis for GRACES), which is a pipeline reducing spectra from GRACES (Gemini Remote Access to the CFHT ESPaDOnS Spectrograph) at the Gemini North Telescope. The code is written in the IDL language. It is designed to find all the GRACES frames in a given directory, automatically determine the list of bias, flat, arc and science frames, and perform the whole reduction and extraction within a few minutes. We compare the output from DRAGraces with that of OPERA, a pipeline developed at CFHT that also can extract GRACES spectra. Both pipelines were developed completely independently, yet they give very similar extracted spectra. They both have their advantages and disadvantages. For instance, DRAGraces is more straightforward and easy to use and is less likely to be derailed by a parameter that needs to be tweaked, while OPERA offers a more careful extraction that can be significantly superior when the highest resolution is required and when the signal-to-noise ratio is low. One should compare both before deciding which one to use for their science. Yet, both pipelines deliver a fairly comparable resolution power (R~52.8k and 36.6k for DRAGraces and R~58k and 40k for OPERA in high and low-resolution spectral modes, respectively), wavelength solution and signal-to-noise ratio per resolution element.

description: We define, for a locally compact quantum group $G$ in the sense of Kustermans--Vaes, the space of $LUC(G)$ of left uniformly continuous elements in $L^\infty(G)$. This definition covers both the usual left uniformly continuous functions on a locally compact group and Granirer's uniformly continuous functionals on the Fourier algebra. We show that $LUC(G)$ is an operator system containing the $C^*$-algebra $C_0(G)$ and contained in its multiplier algebra $M(C_0(G))$. We use this to partially answer an open problem by Bedos--Tuset: if $G$ is co-amenable, then the existence of a left invariant mean on $M(C_0(G))$ is sufficient for $G$ to be amenable. Furthermore, we study the space $WAP(G)$ of weakly almost periodic elements of $L^\infty(G)$: it is a closed operator system in $L^\infty(G)$ containing $C_0(G)$ and--for co-amenable $G$--contained in $LUC(G)$. Finally, we show that--under certain conditions, which are always satisfied if $G$ is a group--the operator system $LUC(G)$ is a $C^*$-algebra.

description: Manually authoring 3D shapes is difficult and time consuming; generative models of 3D shapes offer compelling alternatives. Procedural representations are one such possibility: they offer high-quality and editable results but are difficult to author and often produce outputs with limited diversity. On the other extreme are deep generative models: given enough data, they can learn to generate any class of shape but their outputs have artifacts and the representation is not editable. In this paper, we take a step towards achieving the best of both worlds for novel 3D shape synthesis. We propose ShapeAssembly, a domain-specific "assembly-language" for 3D shape structures. ShapeAssembly programs construct shapes by declaring cuboid part proxies and attaching them to one another, in a hierarchical and symmetrical fashion. Its functions are parameterized with free variables, so that one program structure is able to capture a family of related shapes. We show how to extract ShapeAssembly programs from existing shape structures in the PartNet dataset. Then we train a deep generative model, a hierarchical sequence VAE, that learns to write novel ShapeAssembly programs. The program captures the subset of variability that is interpretable and editable. The deep model captures correlations across shape collections that are hard to express procedurally. We evaluate our approach by comparing shapes output by our generated programs to those from other recent shape structure synthesis models. We find that our generated shapes are more plausible and physically-valid than those of other methods. Additionally, we assess the latent spaces of these models, and find that ours is better structured and produces smoother interpolations. As an application, we use our generative model and differentiable program interpreter to infer and fit shape programs to unstructured geometry, such as point clouds.

description: We performed elastic neutron scattering experiments on solid solution CeRh1-xCoxIn5 with x=0.4 to clarify the nature of the antiferromagnetic (AF) phase in the vicinity of the quantum critical point. We observed the incommensurate AF order below T_Nh=3.5 K. The structure of the incommensurate AF order is basically unchanged from that for pure CeRhIn5. We further found the evolution of a new commensurate AF order with the modulation of q_c=(1/2,1/2,1/2) below T_Nc=2.9 K. The volume-averaged moments for the incommensurate and commensurate AF phases are 0.38 mu_B/Ce and 0.21 mu_B/Ce, respectively, which are reduced from the incommensurate AF moment (0.75 mu_B/Ce) for pure CeRhIn5. We suggest from these results that the commensurate magnetic correlation may be tightly coupled with the superconductivity observed below T_c=1.4 K.

description: Barriers to the migration of fish limit access to suitable habitat and have been identified as a major contributor to the decline of freshwater fish species. GIS and fine scale elevation data were used to create a model to identify physical barriers to fish migration on the Cotter River in the ACT, Australia. The effect of spatial resolution on the efficacy of the model was also examined. Elevation data gridded at 1m, 5m, 10m and 20m were used to simulate the terrain. Two types of models were analysed for barrier identification: logistic regression and non-hierarchical clustering. Logistic regression based on 1m resolution terrain data was found to create the best models. The 1m model using transect averages predicted 88% of the barriers identified in the field. The relative steepness parameter was found to be a key variable for predicting barriers. A general trend of increased accuracy of barrier prediction of field surveyed barriers with a decrease in grid cell size was found for grid spacing less than 20m. The model allows for a semi-automated process to rapidly assess catchments for instream barriers to fish passage. The predictions from the model provide the means for prioritizing areas containing possible physical barriers in the Cotter River. It is intended to be used in conjunction with traditional barrier identification.

description: We present a simple nonlinear digital pre-distortion (DPD) of optical transmitter components, which consists of concatenated blocks of a finite impulse response (FIR) filter, a memoryless nonlinear function and another FIR filter. The model is a Wiener-Hammerstein (WH) model and has essentially the same structure as neural networks or multilayer perceptions. This awareness enables one to achieve complexity-efficient DPD owing to the model-aware structure and exploit the well-developed optimization scheme in the machine learning field. The effectiveness of the method is assessed by electrical and optical back-to-back (B2B) experiments, and the results show that the WH DPD offers a 0.52-dB gain in signal-to-noise ratio (SNR) and 6.0-dB gain in optical modulator output power at a fixed SNR over linear-only DPD.

description: Herein is discussed the performance of spaceborne nulling interferometers searching for extra-solar planets, in terms of their extinction maps projected on-sky. In particular, it is shown that the designs of Spatial Filtering (SF) and Achromatic Phase Shifter (APS) subsystems, both required to achieve planet detection and characterization, can sensibly affect the nulling maps produced by a simple Bracewell interferometer. Analytical relationships involving cross correlation products are provided and numerical simulations are performed, demonstrating marked differences in the aspect of extinction maps and the values of attained fringes contrasts. It is concluded that depending on their basic principles and designs, FS and APS will result in variable capacities for serendipitous discoveries of planets orbiting around their parent star. The mathematical relationships presented in this paper are assumed to be general, i.e. they should apply to other types of multi-apertures nulling interferometers.

description: The study of adverse childhood experiences and their consequences has emerged over the past 20 years. In this study, we aimed to leverage explainable artificial intelligence, and propose a proof-of-concept prototype for a knowledge-driven evidence-based recommendation system to improve surveillance of adverse childhood experiences. We used concepts from an ontology that we have developed to build and train a question-answering agent using the Google DialogFlow engine. In addition to the question-answering agent, the initial prototype includes knowledge graph generation and recommendation components that leverage third-party graph technology. To showcase the framework functionalities, we here present a prototype design and demonstrate the main features through four use case scenarios motivated by an initiative currently implemented at a children hospital in Memphis, Tennessee. Ongoing development of the prototype requires implementing an optimization algorithm of the recommendations, incorporating a privacy layer through a personal health library, and conducting a clinical trial to assess both usability and usefulness of the implementation. This semantic-driven explainable artificial intelligence prototype can enhance health care practitioners ability to provide explanations for the decisions they make.

description: 5D superconformal theories involve vacuum valleys characterized in the simplest case by the vacuum expectation value of a real scalar field. If it is nonzero, conformal invariance is spontaneously broken and the theory is not renormalizable. In the conformally invariant sector with zero scalar v.e.v., the theory is intrinsically nonperturbative. We study classical and quantum dynamics of this theory in the limit when field dependence of the spatial coordinates is disregarded. The classical trajectories ``fall'' on the singularity at the origin of scalar moduli space. The quantum spectrum involves ghost states with unbounded from below negative energies, but such states fail to form complete 16-plets as is dictated by the presence of four complex supercharges and should be rejected by that reason. Physical excited states come in supermultiplets and have all positive energies. We conjecture that the spectrum of the complete field theory hamiltonian is nontrivial and has a similar nontrivial ghost-free structure and also speculate that the ghosts in higher-derivative supersymmetric field theories are exterminated by a similar mechanism.

The hierarchy of rogue wave solutions in nonlinear systems
Creators: name: Kedziora, David Jacob
Publisher: name: The Australian National University
Year: 2018

description: Oceanic freak waves, optical spikes and extreme events in numerous contexts can arguably be modelled by modulationally unstable solutions within nonlinear systems. In particular, the fundamental nonlinear Schroedinger equation (NLSE) hosts a high-amplitude spatiotemporally localised solution on a plane-wave background, called the Peregrine breather, which is generally considered to be the base-case prototype of a rogue wave. Nonetheless, until very recently, little was known about what to expect when observing or engineering entire clusters of extreme events. Accordingly, this thesis aims to elucidate this matter by investigating complicated structures formed from collections of Peregrine breathers. Many novel NLSE solutions are discovered, all systematically classifiable by their geometry. The methodology employed here is based on the well-established concept of Darboux transformations, by which individual component solutions of an integrable system are nonlinearly superimposed to form a compound wavefunction. It is primarily implemented in a numerical manner within this study, operating on periodically modulating NLSE solutions called breathers. Rogue wave structures can only be extracted at the end of this process, when a limit of zero modulation frequency is applied to all components. Consequently, a requirement for breather asymmetry ensures that a multi-rogue wavefunction must be formed from a triangular number of individual Peregrine breathers (e.g. 1, 3, 6, 10, ...), whether fused or separated. Furthermore, the arrangements of these are restricted by a maximum phase-shift allowable along an evolution trajectory through the relevant wave field. Ultimately, all fundamental high-order rogue wave solutions can be constructed via polynomial relations between origin-translating component shifts and squared modulation frequency ratios. They are simultaneously categorisable by both these mathematical existence conditions and the corresponding visual symmetries, appearing spatiotemporally as triangular cascades, pentagrams, heptagrams, and so on. These parametric relations do not conflict with each other, meaning that any arbitrary NLSE rogue wave solution can be considered a hybridisation of this elementary set. Moreover, this hierarchy of structures is significantly general, with complicated arrangements persisting even on a cnoidal background.
