description: We present ac susceptibility measurements with the frequency spanning three orders of magnitude on single grain, icosahedral R - Mg - Zn (R = rare earth) quasicrystals. The freezing temperature in Gd-based, Heisenberg spin glasses in this family increases by ~ 2% with a frequency increase from 10 Hz to 10 kHz, whereas the freezing temperature in the non-Heisenberg members of the family is significantly more responsive to the frequency change (by 16 - 22 %), suggesting that an additional magnetic anisotropy distribution in the non-Heisenberg spin glasses causes changes in the low frequency magnetic dynamics.

description: In this paper we report a new high-pressure rhombohedral phase of Ce2Zr2O8 observed from high-pressure angle-dispersive x-ray diffraction and Raman spectroscopy studies up to nearly 12 GPa. The ambient-pressure cubic phase of Ce2Zr2O8 transforms to a rhombohedral structure beyond 5 GPa with a feeble distortion in the lattice. Pressure evolution of unit-cell volume showed a change in compressibility above 5 GPa. The unit-cell parameters of the high-pressure rhombohedral phase at 12.1 GPa are ah = 14.6791(3) Å, ch = 17.9421(5) Å, V = 3348.1(1) Å3. The structure relation between the parent cubic (P2_13) and rhombohedral (P3_2) phases were obtained by group-subgroup relations. All the Raman modes of the cubic phase showed linear evolution with pressure with the hardest one at 197 cm-1. Some Raman modes of the high-pressure phase have a non-linear evolution with pressure and softening of one low-frequency mode with pressure is found. The compressibility, equation of state, and pressure coefficients of Raman modes of Ce2Zr2O8 are also reported.

description: We investigate how the topological charge density in lattice QCD simulations is affected by violations of chiral symmetry in different fermion actions. To this end we compare lattice configurations generated with a number of different actions including first configurations generated with exact overlap quarks. We visualize the topological profiles after mild smearing. In the topological charge correlator we measure the size of the positive core, which is known to vanish in the continuum limit. To leading order we find the core size to scale linearly with the lattice spacing with the same coefficient for all actions, even including quenched simulations. In the subleading term the different actions vary over a range of about 10 %. Our findings suggest that non-chiral lattice actions at current lattice spacings do not differ much for this specific observable related to topology, both among themselves and compared to overlap fermions.

description: Granular Solid Hydrodynamics (GSH) is a broad-ranged continual mechanical description of granular media capable of accounting for static stress distributions, yield phenomena, propagation and damping of elastic waves, the critical state, shear band, and fast dense flow. An important input of GSH is an expression for the elastic energy needed to deform the grains. The original expression, though useful and simple, has some draw-backs. Therefore, a slightly more complicated expression is proposed here that eliminates three of them: (1) The maximal angle at which an inclined layer of grains remains stable is increased from $26^\circ$ to the more realistic value of $30^\circ$. (2)Depending on direction and polarization, transverse elastic waves are known to propagate at slightly different velocities. The old expression neglects these differences, the new one successfully reproduces them. (3) Most importantly, the old expression contains only the Drucker-Prager yield surface. The new one contains in addition those named after Coulomb, Lade-Duncan and Matsuoka-Nakai -- realizing each, and interpolating between them, by shifting a single scalar parameter.
The Semi-Chiral Quotient, Hyperkahler Manifolds and T-duality

description: We study the construction of generalized Kahler manifolds, described purely in terms of N=(2,2) semichiral superfields, by a quotient using the semichiral vector multiplet. Despite the presence of a b-field in these models, we show that the quotient of a hyperkahler manifold is hyperkahler, as in the usual hyperkahler quotient. Thus, quotient manifolds with torsion cannot be constructed by this method. Nonetheless, this method does give a new description of hyperkahler manifolds in terms of two-dimensional N=(2,2) gauged non-linear sigma models involving semichiral superfields and the semichiral vector multiplet. We give two examples: Eguchi-Hanson and Taub-NUT. By T-duality, this gives new gauged linear sigma models describing the T-dual of Eguchi-Hanson and NS5-branes. We also clarify some aspects of T-duality relating these models to N=(4,4) models for chiral/twisted-chiral fields and comment briefly on more general quotients that can give rise to torsion and give an example.

Publisher: name: University of Calgary
Year: 2005

description: Bibliography: p. 152-159
description: Gas hydrates upon dissociation release fresh water and large volumes of gas into the sediment structure causing significant increases in pore fluid pressures and substantial reduction in soil strengths. In order to assess the role that gas hydrates play in submarine slope stability, a comprehensive literature review has been carried out. The history of gas hydrates, their physical properties, hydrate stability, formation, and dissociation, and the occurrence and detection of gas hydrates are all reviewed and discussed. This report presents a parametric analysis of the impact of gas hydrate dissociation on the stability of seabed soils. Using a material model which describes the stress changes induced by hydrate decomposition, coupled with two methods of slope stability analysis, the effects of gas hydrates were evaluated. The results show that a slope containing gas hydrates becomes less stable with decreasing water depth, decreasing overburden thickness above the hydrate bearing layer, increasing void ratio, and decreasing plasticity index.

description: We report on near-infrared J- and H-band linear polarimetric photometry of eight ultracool dwarfs (two late-M, five L0-L7.5, and one T2.5) with known evidence for photometric variability due to dust clouds, anomalous red infrared colors, or low-gravity atmospheres. The polarimetric data were acquired with the LIRIS instrument on the William Herschel Telescope. We also provide mid-infrared photometry in the interval 3.4-24 micron for some targets obtained with Spitzer and WISE, which has allowed us to confirm the peculiar red colors of five sources in the sample. We can impose modest upper limits of 0.9% and 1.8% on the linear polarization degree for seven targets with a confidence of 99%. Only one source, 2MAS, J02411151-0326587 (L0), appears to be strongly polarized (P ~ 3%) in the J-band with a significance level of P/sigma_P ~ 10. The likely origin of its linearly polarized light and rather red infrared colors may reside in a surrounding disk with an asymmetric distribution of grains. Given its proximity (66 +/- 8 pc), this object becomes an excellent target for the direct detection of the disk.

Probabilistic Traffic Forecasting with Dynamic Regression

Year: 2023

description: This paper proposes a dynamic regression (DR) framework that enhances existing deep spatiotemporal models by incorporating structured learning for the error process in traffic forecasting. The framework relaxes the assumption of time independence by modeling the error series of the base model (i.e., a well-established traffic forecasting model) using a matrix-variate autoregressive (AR) model. The AR model is integrated into training by redesigning the loss function. The newly designed loss function is based on the likelihood of a non-isotropic error term, enabling the model to generate probabilistic forecasts while preserving the original outputs of the base model. Importantly, the additional parameters introduced by the DR framework can be jointly optimized alongside the base model. Evaluation on state-of-the-art (SOTA) traffic forecasting models using speed and flow datasets demonstrates improved performance, with interpretable AR coefficients and spatiotemporal covariance matrices enhancing the understanding of the model.

description: This short but self-contained survey presents a number of elegant matrix/operator inequalities for general convex or concave functions, obtained with a unitary orbit technique. Jensen, sub or super-additivity type inequalities are considered. Some of them are substitutes to classical inequalities (Choi, Davis, Hansen-Pedersen) for operator convex or concave functions. Various trace, norm and determinantal inequalities are derived. Combined with an interesting decomposition for positive semi-definite matrices, several results for partitioned matrices are also obtained.

description: We study theoretically the shapes of a dividing epithelial monolayer of cells lying on top of an elastic stroma. The negative tension created by cell division provokes a buckling instability at a finite wave vector leading to the formation of periodic arrays of villi and crypts. The instability is similar to the buckling of a metallic plate under compression. We use the results to rationalize the various structures of the intestinal lining observed \emph{in vivo}. Taking into account the coupling between cell division and local curvature, we obtain different patterns of villi and crypts, which could explain the different morphologies of the small intestine and the colon.

description: We report the results of a CCD imaging survey, complimented by astrometric and spectroscopic follow-up studies, that aims to probe the fate of heavy-weight intermediate mass stars by unearthing new, faint, white dwarf members of the rich, nearby, intermediate age open clusters NGC3532 and NGC2287. We identify a total of four white dwarfs with distances, proper motions and cooling times which can be reconciled with membership of these populations. We find that WDJ0643-203 in NGC2287, with an estimated mass of M=1.02-1.16Msun, is potentially the most massive white dwarf so far identified within an open cluster. Guided by the predictions of modern theoretical models of the late-stage evolution of heavy-weight intermediate mass stars, we conclude that there is a distinct possibility it has a core composed of O and Ne. We also determine that despite the cooling times of the three new white dwarfs in NGC3532 and the previously known degenerate member NGC3532-10 spanning ~90Myr, they all have remarkably similar masses (M~0.9-1Msun). This is fully consistent with the results from our prior work on a heterogeneous sample of ~50 white dwarfs from 12 stellar populations, on the basis of which we argued that the stellar initial mass-final mass relation is less steep at Minit>4Msun than in the adjacent lower initial mass regime. This change in the gradient of the relation could account for the secondary peak observed in the mass distribution of the field white dwarf population and mitigate the need to invoke close binary evolution to explain its existence. Spectroscopic investigation of numerous additional candidate white dwarf members of NGC3532 unearthed by a recent independent study would be useful to confirm (or otherwise) these conclusions.

description: Some inflationary models predict the existence of isocurvature primordial fluctuations, in addition to the well known adiabatic perturbation. Such mixed models are not yet ruled out by available data sets. In this paper we explore the possibility of obtaining better constraints on the isocurva- ture contribution from future astronomical data. We consider the axion and curvaton inflationary scenarios, and use Planck satellite experimental specifications together with SDSS galaxy survey to forecast for the best parameter error estimation by means of the Fisher information matrix formal- ism. In particular, we consider how CMB lensing information can improve this forecast. We found substantial improvements for all the considered cosmological parameters. In the case of isocurvature amplitude this improvement is strongly model dependent, varying between less than 1% and above 20% around its fiducial value. Furthermore, CMB lensing enables the degeneracy break between the isocurvature amplitude and correlation phase in one of the models. In this sense, CMB lensing information will be crucial in the analysis of future data.

Archetypal Analysis++: Rethinking the Initialization Strategy

Publisher: name: arXiv
Year: 2023
Subjects: subject: Machine Learning (cs.LG)
subject: FOS: Computer and information sciences

description: Archetypal analysis is a matrix factorization method with convexity constraints. Due to local minima, a good initialization is essential, but frequently used initialization methods yield either sub-optimal starting points or are prone to get stuck in poor local minima. In this paper, we propose archetypal analysis++ (AA++), a probabilistic initialization strategy for archetypal analysis that sequentially samples points based on their influence on the objective function, similar to $k$-means++. In fact, we argue that $k$-means++ already approximates the proposed initialization method. Furthermore, we suggest to adapt an efficient Monte Carlo approximation of $k$-means++ to AA++. In an extensive empirical evaluation of 15 real-world data sets of varying sizes and dimensionalities and considering two pre-processing strategies, we show that AA++ almost always outperforms all baselines, including the most frequently used ones.

From ranch to realty: the landscape history and heritage of former settlement schemes in the Bow Valley, west of Calgary, Alberta
Creators: name: Barge, Judith Victoria
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 229-243
description: This research focuses on the historic landscapes and heritage of the former settlement schemes of Mitford, Glenbow and Bowness Estates in the Bow Valley west of Calgary, Alberta. These settlement schemes were founded by privileged British and American settlers who had come to western Canada with the original intention of taking up ranching. The settlement of Mitford was founded towards the end of the 19th century, while Glenbow and Bowness arose in the early 20th century. The author has explained how these settlement schemes originated, their nature and development, and the reasons for their demise. In this regard, the author has considered not only the physical historic environment, but also where possible, the roles and thoughts of the people involved. In addition, the author has included a comparative analysis of these settlement schemes. The geographic area containing the remnants of these former settlement schemes was previously utilized as one of the major ranches in southern Alberta. In the last decade this area of land has been altered at an unprecedented rate by increasing urbanization with the result that much potential heritage has been lost. Therefore the author has provided an inventory of the remaining heritage of these settlement schemes. The author concludes by suggesting a plan for a heritage/recreation trail that could incorporate the significant heritage of Mitford, Glenbow and Bowness Estates.
Simulation and evaluation of the performance of the proposed Mars network constellation for positioning, orbit improvement, and establishment of a spatial reference frame for Mars

Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 175-182
description: In 1999, the NASA Jet Propulsion Lab presented a proposal for a six satellite navigation and communication network for Mars called the Mars Network. This thesis investigates the performance of the Mars Network both theoretically, using figures of merit commonly applied to satellite navigation systems on Earth, and in the position domain using simulated observations. The Mars Network is evaluated in terms of availability, accuracy, and reliability as a function of position and time by simulating network geometry for users distributed across the planet. The Network is found to provide the best service to users in equatorial and polar regions. Instantaneous positioning is limited due to the small number of satellites in the constellation. The addition of a height constraint is shown to increase the availability of instantaneous positioning. End-to-end simulation tools are developed for the simulation of Mars Network observations. The trajectories of the satellites are precisely modelled using numerical methods. Models are developed and implemented for the most significant error sources, including the effects on the navigation signals of the Mars ionosphere and troposphere. After the effect of orbital errors, the ionospheric effect is found to be the next largest error source. A positioning and orbit determination algorithm is developed based on a decentralized processing strategy that only requires network elements to exchange state vectors and covariance matrices while making observations of each other. The algorithm is tested in several scenarios using a simulated range and Doppler observations between the six Mars Network satellites and eight simulated landers. The ability of the Mars Network to position landers with sparse observations is demonstrated. The Mars Network is shown to be able to position landers on Mars to accuracies of 10 m after several hours of intermittent tracking. The limiting factor is found to be the growth of orbital errors. The ability of current and future lander missions to provide ground control for improving orbits and to improve lander positioning performance is demonstrated. The effect of inter-satellite observations is investigated. Recommendations are given for ways to improve the navigation performance of the constellation and areas of future research are discussed.
The off-prescription use of modafinil and methylphenidate: Perceived risks, benefits and impact on cognitive function
Creators: name: Teodorini, Rachel Deborah
Publisher: name: London South Bank University
Year: 2021

description: Many psychoactive pharmaceuticals, in addition to their intended clinical benefits, can also enhance cognitive functions in healthy populations. Popularity in cognitive enhancing drug (CED) use has raised concerns about its possible risks and harms. Modafinil and methylphenidate are, perhaps, the most consumed CEDs. This thesis sought to understand more about the modafinil and methylphenidate off-prescription user and whether they are self-medicating for poor cognitive performance or enhancing. Study 1, an online survey advertised on forum sites to reach the CED-using and student populations, revealed that CED users are mostly male, North American or British, educated, employed and in their mid-20s. Use of CEDs was associated with recreational drug use and psychiatric disorders. Daily use of modafinil was reported as providing the most benefits and that benefits increased with more frequent use. Modafinil was perceived as safe, whereas methylphenidate was perceived as more dangerous. Study 1 could not assess whether CED-using respondents were self-medicating or enhancing, therefore, Study 2, an online survey, addressed this via the Cognitive Failures Questionnaire (Broadbent, Cooper, Fitzgerald & Parks, 1982), the General Procrastination Questionnaire (Lay, 1986), and the Adult ADHD Self-Report Scale, in addition to questions on CED and recreational drug use. The results revealed that the CED-user groups reported having problems with inattention and procrastination compared with controls. Study 3, an experimental study, sought to verify this objectively. The cognitive performance of 43 reported off-prescription users of modafinil and methylphenidate and 47 controls was tested using the Arrow Flanker Task (Ridderinkhof, van der Molen, Band & Bashore, 1997) and the Antisaccade task (Hallett, 1978), together with the self-report Behaviour Rating Inventory of Executive Function - Adults questionnaire (Gioia, Isquith, Guy & Kenworthy, 2000). The results indicated that the CED-user group demonstrated good cognitive performance and therefore were likely to be enhancing rather than self-medicating. The implications of these findings are discussed in relation to future research, ethical debates, and government policy.

description: Immigrants coming to Canada have increased in the last three decades. Serious mental health problems exist among immigrant women, therefore the primary purpose of this study was to increase awareness and understanding of what would be helpful in meeting their mental health needs. Informed by post-colonial feminist perspective and Kleinman's explanatory model this qualitative exploratory study was conducted with seven health care providers who provided mental health services to immigrant women. In-depth interviews were used to obtain information about the women's mental health care experiences. The study's findings reveal that (a) immigrant women have difficulties accessing mental health care services due to insufficient language skills, unfamiliarity/unawareness of services and low socio economic status; (b) cultural background exerts positive and negative influences; ( c) health care provider-client relationship had profound effects on the immigrant woman seeking help. Strategies are suggested to help provide more culturally appropriate and accessible mental health care for immigrant women.

description: Circumstellar disks are the cradles of planetary systems and their physical and chemical properties directly influence the planet formation process. As most planets supposedly form in the inner disk regions, i.e., within a few tens of AU, it is crucial to study circumstellar disk on these scales to constrain the conditions for planet formation. Our aims are to characterize the inner regions of the circumstellar disk around the young Herbig Ae/Be star HD97048 in polarized light. We use VLT/NACO to observe HD97048 in polarimetric differential imaging (PDI) mode in the H and Ks band. We spatially resolve the disk around HD97048 in polarized flux in both filters on scales between ~0.1"-1.0" corresponding to the inner ~16-160 AU. Fitting isophots to the flux calibrated H-band image between 13 - 14 mag/arcsec^2 and 14 - 15 mag/arcsec^2 we derive a apparent disk inclination angle of 34+-5 deg and 47+-2 deg, respectively. The disk position angle in both brightness regimes is almost identical and roughly 80 deg. Along the disk major axis the surface brightness of the polarized flux drops from ~11 mag/arcsec^2 at ~0.1" (~16 AU) to ~15.3 mag/arcsec^2 at ~1.0" (~160 AU). The brightness profiles along the major axis are fitted with power-laws falling off as ~r^(-1.78+-0.02) in H and ~r^(-2.34+-0.04) in Ks. As the surface brightness drops off more rapidly in Ks compared to H the disks becomes relatively bluer at larger separations possibly indicating changing dust grain properties as a function of radius. For the first time the inner ~0.1"-1.0" (~16-160 AU) of the surface layer of the HD97048 circumstellar disk have been imaged in scattered light demonstrating the power of ground-based imaging polarimetry. Our data fill an important gap in a large collection of existing data including resolved thermal dust and PAH emission images as well as resolved gas emission lines.

description: By means of exact diagonalizations, the Bernevig-Hughes-Zhang model at quarter-filling in the limit of strong Hubbard on-site repulsion is investigated. We find that the non-interacting metallic state will be turned into a Chern insulator with saturated magnetization under strong correlations. That is, at such a metal-insulator transition, both the topological and the magnetic properties of the system are changed due to spontaneous breaking of time reversal symmetry in the ground states. According to our findings, this topological phase transition seems to be of first order. Our results illustrate the interesting physics in topological Mott transitions and provide guidance to the search of more interaction-induced topological phases in similar systems.

description: We present a method to measure the magnetic properties of monolayers and ultra-thin films of magnetic material. The method is based on low energy muon spin rotation and $β$-detected nuclear magnetic resonance measurements. A spin probe is used as a "proximal" magnetometer by implanting it in the substrate, just below the magnetic material. We calculate the expected magnetic field distribution sensed by the probe and discuss its temperature and implantation depth dependencies. This method is highly suitable for measuring the magnetic properties of monolayers of single molecule magnets, but can also be extended to ultra-thin magnetic films.

description: We present the results of astrometic observations of H2O masers associated with the star forming region G192.16-3.84 with the VLBI Exploration of Radio Astrometry (VERA). The H2O masers seem to be associated with two young stellar objects (YSOs) separated by \sim1200 AU as reported in previous observations. In the present observations, we successfully detected an annual parallax of 0.66 \pm 0.04 mas for the H2 O masers, which corresponds to a distance to G192.16-3.84 of D = 1.52 \pm 0.08 kpc from the Sun. The determined distance is shorter than the estimated kinematic distance. Using the annual parallax distance and the estimated parameters of the millimeter continuum emission, we estimate the mass of the disk plus circumstellar cloud in the southern young stellar object to be 10.0+4.3M\cdot. We also estimate the galactocentric distance and the peculiar motion -3.6 of G192.16-3.84, relative to a circular Galactic rotation: R\star = 9.99 \pm 0.08 kpc, Z\star = -0.10 \pm 0.01 kpc, and (U\star,V\star,W\star)=(-2.8\pm1.0,-10.5\pm0.3,4.9\pm2.7)[kms-1]respectively. The peculiar motion of G192.16-3.84 is within that typically found in recent VLBI astrometric results. The angular distribution and three-dimensional velocity field of H2O maser features associated with the northern YSO indicate the existence of a bipolar outflow with a major axis along the northeast-southwest direction.

description: A two qubit quantum gate, namely the C-Phase, has been realized by exploiting the longitudinal momentum (i.e. the optical path) degree of freedom of a single photon. The experimental setup used to engineer this quantum gate represents an advanced version of the high stability closed-loop interferometric setup adopted to generate and characterize 2-photon 4-qubit Phased Dicke states. Some experimental results, dealing with the characterization of multipartite entanglement of the Phased Dicke states are also discussed in detail.

description: We use numerical models, supported by our laboratory data, to predict the dust densities of ejecta outflux at any altitude within the Hill spheres of Europa and Ganymede. The ejecta are created by micrometeoroid bombardment and five different dust populations are investigated as sources of dust around the moons. The impacting dust flux (influx) causes the ejection of a certain amount of surface material (outflux). The outflux populates the space around the moons, where a part of the ejecta escapes and the rest falls back to the surface. These models were validated against existing Galileo DDS (Dust Detector System) data collected during Europa and Ganymede flybys. Uncertainties of the input parameters and their effects on the model outcome are also included. The results of this model are important for future missions to Europa and Ganymede, such as JUICE (JUpiter ICy moon Explorer), recently selected as ESA's next large space mission to be launched in 2022.
Das spätkaiserzeitliche-frühvölkerwanderungszeitliche Gräberfeld von Lampertheim (Bergstraße)

description: Vor fast 90 Jahren wurde im Südhessischen Lampertheim (Lkr. Bergstraße) das spätantike germanisch geprägte Gräberfeld „Am Kurzen Klippelacker“ entdeckt und ausgegraben. Mit seinen über 50 Bestattungen ist es bis heute der einzige Bestattungsplatz dieser Größe auf ehemals römischem rechtsrheinischem Gebiet. Aufgrund dessen, und der Lage am Rhein fast unmittelbar gegenüber der alten Niebelungenstadt Worms, war das Gräberfeld regelmäßig Bestandteil unterschiedlichster Beiträge. Bezüglich der Datierung, Umstände und besonders der ethnischen Zuordnung wurden immer wieder einige Teilaspekte beleuchtet. Dass eine ausführliche Untersuchung des gesamten Gräberfeldes seit der Erstveröffentlichung 1936 jedoch nicht vorlag, war 2012 Anlass einer Magisterarbeit, die hier nun in bearbeiteter vollständiger Form vorliegt.

Optical phase dynamics in mutually coupled diode laser systems exhibiting power synchronization

description: We probe the physical mechanism behind the known phenomenon of power synchronization of two diode lasers that are mutually coupled via their delayed optical fields. In a diode laser, the amplitude and the phase of the optical field are coupled by the so-called linewidth enhancement factor, $α$. In this work, we explore the role of optical phases of the electric fields in amplitude (and hence power) synchronization through $α$ in such mutually delay-coupled diode laser systems. Our numerical results show that the synchronization of optical phases drives the powers of lasers to synchronized death regimes. We also find that as $α$ varies for different diode lasers, the system goes through a sequence of in-phase amplitude-death states. Within the windows between successive amplitude-death regions, the cross-correlation between the field amplitudes exhibits a universal power-law behaviour with respect to $α$.

description: Highway traffic states data collected from a network of sensors can be considered a high-dimensional nonlinear dynamical system. In this paper, we develop a novel data-driven method -- anti-circulant dynamic mode decomposition with sparsity-promoting (circDMDsp) -- to study the dynamics of highway traffic speed data. Particularly, circDMDsp addresses several issues that hinder the application of existing DMD models: limited spatial dimension, presence of both recurrent and non-recurrent patterns, high level of noise, and known mode stability. The proposed circDMDsp framework allows us to numerically extract spatial-temporal coherent structures with physical meanings/interpretations: the dynamic modes reflect coherent spatial bases, and the corresponding temporal patterns capture the temporal oscillation/evolution of these dynamic modes. Our result based on Seattle highway loop detector data showcases that traffic speed data is governed by a set of periodic components, e.g., mean pattern, daily pattern, and weekly pattern, and each of them has a unique spatial structure. The spatiotemporal patterns can also be used to recover/denoise observed data and predict future values at any timestamp by extrapolating the temporal Vandermonde matrix. Our experiments also demonstrate that the proposed circDMDsp framework is more accurate and robust in data reconstruction and prediction than other DMD-based models.
