description: Within the Green's function and equations of motion formalism it is possible to exactly solve a large class of models useful for the study of strongly correlated systems. Here, we present the exact solution of the one-dimensional extended Hubbard model with on-site $U$ and first nearest neighbor repulsive V interactions in the presence of an external magnetic field h, in the narrow band limit. At zero temperature our results establish the existence of four phases in the three-dimensional space (U, n, h) - n is the filling - with relative phase transitions, as well as different types of charge ordering. The magnetic field may dramatically affect the behavior of thermodynamic quantities, inducing, for instance, magnetization plateaus in the magnetization curves, and a change from a single to a double-peak structure in the specific heat. According to the value of the particle density, we find one or two critical fields, marking the beginning of full or partial polarization. A detailed study of several thermodynamic quantities is also presented at finite temperature.

description: The Lagrangian view of passive scalar turbulence has recently produced interesting results and interpretations. Innovations in theory, experiments, simulations and data analysis of Lagrangian turbulence are reviewed here in brief. Part of the review is closely related to the so-called Kraichnan model for the advection of the passive scalar in synthetic turbulence. Possible implications for a better understanding of the passive scalar mixing in Navier-Stokes turbulence are also discussed.

The effects of entity and incremental views of ability and goal orientation on performance
Creators: name: Muskett, S
Publisher: name: University Of Tasmania
Year: 2023

description: This review assesses the implications of implicit views of ability; comparing the belief that intelligence is a stable, unchangeable trait (an entity view) with the belief that it is a repertoire of skills that can be expanded upon with learning and practice (an incremental view). Links between views of ability and goal orientation are examined, focusing on social comparison goals (where the primary aim is to vindicate one's ability in the eyes of other people) and mastery goals (where the primary aim is to achieve a criterion level of performance). A social.cognitive model examining these associations is assessed and the behavioural consequences of endorsing each of the fore~mentioned views of ability are highlighted. Links between views of ability and confidence in ability, attributional tendencies, as well as gender and age differences are also explored. Research suggests that people holding an incremental view of ability are more likely to pursue mastery goals resulting in more adaptive learning patterns, greater persistence and feeling challenged by failure. While people holding entity views are more likely to subscribe to social comparison goals resulting in less adaptive behaviours, such as decreased persistence. Further research assessing the extent to which experimental findings are generalisable to naturalistic settings is advised, as well as the role of persistence as it relates to views of ability and goal choice.

The galaxy-wide distributions of mean electron density in the HII regions of M51 and NGC 4449

description: Using ACS-HST images to yield continuum subtracted photometric maps in Hαof the Sbc galaxy M51 and the dwarf irregular galaxy NGC 4449, we produced extensive (over 2000 regions for M51, over 200 regions for NGC4449) catalogues of parameters of their HII regions: their Hαluminosities, equivalent radii and coordinates with respect to the galaxy centers. From these data we derived, for each region, its mean luminosity weighted electron density, , determined from the Hαluminosity and the radius, R, of the region. Plotting these densities against the radii of the regions we find excellent fits for varying as R^{-1/2}. This relatively simple relation has not, as far as we know, been predicted from models of HII region structure, and should be useful in constraining future models. Plotting the densities against the galactocentric radii, r, of the regions we find good exponential fits, with scale lengths of close to 10 kpc for both galaxies. These values are comparable to the scale lengths of the HI column densities for both galaxies, although their optical structures, related to their stellar components are very different. This result indicates that to a first approximation the HII regions can be considered in pressure equilibrium with their surroundings. We also plot the electron density of the HII regions across the spiral arms of M51, showing an envelope which peaks along the ridge lines of the arms.

Spacetime Transformation through Black Hole Jets and Quantum Entanglement in the Framework of the RMB Theory
Creators: name: Dellomonaco, Davide
Publisher: name: Zenodo
Year: 2025
Subjects: RMB Theory, spacetime, black hole, white hole, quantum entanglement, gravitational theory, theoretical physics
plasma jets, general relativity, quantum gravity, speculative physics

description: This work expands the RMB Theory (Space – Matter – Motion) by introducing a novel interpretation of astrophysical jets, as observed at the poles of rotating black holes. It proposes the hypothesis that these jets are not merely energetic outflows from the accretion disk, but rather represent the “exit side” of a physically transformed white hole. Within the RMB framework, the resulting structure is understood as an active spacetime transformation. Furthermore, the possibility of quantum entanglement between two black holes is discussed—specifically, between an entry point and a quantum-entangled exit point—which could offer new insights into the connectivity of spacetime.
To kill a mockingbird : documentation and theory papers

Publisher: name: University Of Tasmania

description: During my sculpturally active years (88-91) I have almost been entirely concerned with the use of the man-made object. Two groups of sculptors in whom I have an interest, the British ie. Cragg, Allington, Woodrow and the Americans ie. Koons, Steinbach, Mccollum, use the manufactured object within their sculptural practice. The British object sculptors use their materials with nostalgia, seeing them as carriers of our collective cultural memory, whilst the Americans have a nihilistic approach, seeing their materials as inert, emptying the product of meaning. I wish to explore both these attitudes towards the object, the metaphorical and the rhetorical in the anticipation of discovering some of my own relationships to the manufactured world. As the work will be experimental numerous pieces will be produced. They will ultimately be of a human scale with the use of furniture and building materials.

Dynamic versus Static Hadronic Structure Functions
Creators: name: Brodsky, Stanley J.
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: "Static" structure functions are the probabilistic distributions computed from the square of the light-front wavefunctions of the target hadron. In contrast, the "dynamic" structure functions measured in deep inelastic lepton-hadron scattering include the effects of rescattering associated with the Wilson line. Initial- and final-state rescattering, neglected in the parton model, can have a profound effect in QCD hard-scattering reactions, producing single-spin asymmetries, diffractive deep inelastic scattering, diffractive hard hadronic reactions, the breakdown of the Lam-Tung relation in Drell-Yan reactions, nuclear shadowing, and non-universal nuclear antishadowing--novel leading-twist physics not incorporated in the light-front wavefunctions of the target computed in isolation. I also review how "direct" higher-twist processes -- where a proton is produced in the hard subprocess itself -- can explain the anomalous proton-to-pion ratio seen in high centrality heavy ion collisions.

description: In colorectal cancer (CRC), both tumor invasion and immunological analysis at the tumor invasive margin (IM) are significantly associated with patient prognosis, but have traditionally been reported independently. We propose a new scoring system, the TGP-I score, to assess the association and interactions between tumor growth pattern (TGP) and tumor infiltrating lymphocytes at the IM and to predict its prognostic validity for CRC patient stratification. The types of TGP were assessed in hematoxylin and eosin-stained whole-slide images. The CD3+ T-cells density at the IM was automatically quantified on immunohistochemical-stained slides using a deep learning method. A discovery (N = 347) and a validation (N = 132) cohorts were used to evaluate the prognostic value of the TGP-I score for overall survival. The TGP-I score3 (trichotomy) was an independent prognostic factor, with higher TGP-I score3 associated with worse prognosis in the discovery (unadjusted hazard ratio [HR] for high vs. low 3.62, 95% confidence interval [CI] 2.22–5.90; p < 0.001) and validation cohort (unadjusted HR for high vs. low 5.79, 95% CI 1.84–18.20; p = 0.003). The relative contribution of each parameter to predicting survival was analyzed. The TGP-I score3 had similar importance compared to tumor-node-metastasis staging (31.2% vs. 32.9%) and was stronger than other clinical parameters. This automated workflow and the proposed TGP-I score could further provide accurate prognostic stratification and have potential value for supporting the clinical decision-making of stage I–III CRC patients.

Essays and documentation of work towards the MFA degree of the University of Tasmania
Creators: name: Marwood, Jim
Publisher: name: University Of Tasmania
Year: 2023

description: Contains essays and documentation of work towards the MFA degree of the University of Tasmania, 1989. The career of South Australian artist Walter Grosser is discussed. His production of stereoscopic photographs is placed in the context of the history of this medium. Scientific investigation of stereoscopic vision up to the present time is summarised, and reasons are sought for the virtual exclusion of the medium from the art world. Although the Arabs may have recognised the importance of binocular vision a thousand years ago, stereopsis was ignored by Western philosophers until Wheatstone's discovery in 1838. Wheatstone's invention of the stereoscope was adapted to photography by Brewster. The device became popular, especially in the United States, where it was developed commercially, importing images, and exporting card-sets and cheap stereoscopes all over the world (including Australia). About 1910, Walter Grosser was struggling to make a living as a commercial photographer in the small South Australian town of Millicent. His commercial work included stereoscopic views but he made also a small opus of unusual and intensely personal work in the medium (illustrated). His photographic production ceased by 1914, probably as a result of wartime anti-German sentiment. After Wheatstone and Brewster, science ignored stereopsis for a century. Research resumed only after the commercial development had virtually ended in the 1930's.. Theories of visual space-perception were based on analogies of camera and range-finder. In 1960 Julesz used computer-generated patterns to show these analogies to be inappropriate. Current theory suggests visual space-perception is achieved by cortical scanning and comparison of the two visual fields. Other 'cue-systems' are usually of secondary importance. The paper ends by suggesting reasons for lack of interest in stereoscopic work such as that of Grosser within the fine arts, and fantasises on connexions yet to be established between stereoscopic photography and holography.
Concentrating the Dark Matter in Galaxy Clusters through Tidal Stripping of Baryonically-Compressed Galactic Halos

Publisher: name: arXiv

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: Gravitational lensing observations of massive X-ray clusters imply a steep characteristic density profile marked by a central concentration of dark matter. The observed mass fraction within a projected radius of 150 kpc is twice that found in state-of-the-art dark matter simulations of the standard Lambda-CDM cosmology. A central baryon enhancement that could explain this discrepancy is not observed, leaving a major puzzle. We propose a solution based on the merger histories of clusters. A significant fraction of the final dark matter content of a cluster halo originates within galaxy-sized halos, in which gas can cool and compress the dark matter core to high densities. The subsequent tidal stripping of this compressed dark matter occurs in denser regions that are closer to the center of the cluster halo. Eventually, the originally cooled gas must be dispersed into the intracluster medium through feedback, for consistency with observations that do not find central baryon enhancements in clusters. Still, the early adiabatic compression of the galactic dark matter leaves a net effect on the cluster. Using a simple model for this process, we show that the central cluster profile is substantially modified, potentially explaining the observed discrepancy.

Localized Cumulative Distributions and a Multivariate Generalization of the Cramér-von Mises Distance
Creators: name: Hanebeck, Uwe D.
name: Klumpp, Vesa
Publisher: name: Karlsruhe
Year: 2008

description: This paper is concerned with distances for comparing multivariate random vectors with a special focus on the case that at least one of the random vectors is of discrete type, i.e., assumes values from a discrete set only. The first contribution is a new type of characterization of multivariate random quantities, the so called Localized Cumulative Distribution (LCD) that, in contrast to the conventional definition of a cumulative distribution, is unique and symmetric. Based on the LCDs of the random vectors under consideration, the second contribution is the definition of generalized distance measures that are suitable for the multivariate case. These distances are used for both analysis and synthesis purposes. Analysis is concerned with assessing whether a given sample stems from a given continuous distribution. Synthesis is concerned with both density estimation, i.e., calculating a suitable continuous approximation of a given sample, and density discretization, i.e., approximation of a given continuous random vector by a discrete one.

Soviet science fiction
Creators: name: Wormeli, Charles Theodore
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this paper is to explore Soviet science fiction; that is, all science fiction published in Russia after 1917 to about 1967. The selection of literature from the 1960's was random; the selection from previous years was determined principally by its availability: about three-fourths of all the works examined belong to the last decade insofar as I can determine from publishing dates and critical sources; somewhat less than three-fourths of all the authors whose works were read wrote mainly in the post World War II era, and half of the novel-length works used in the preparation of the paper were published before World War II. It is impossible to ascertain if these proportions accurately reflect the varying production of science fiction during this period, but it is probably true that much more sf was published in the last decade in Russia than in previous years. What are the themes with which the authors of science fiction are occupied? Have they changed since the 'twenties? How closely does science fiction resemble the rest of Soviet literature? Has it become, as American science fiction after World War II became, a vehicle for social criticism? It is a rapidly growing body of literature that has just recently begun to attract serious consideration of its literary merits. It has a small but devoted audience. I intend to explain what this audience reads and evaluate the genre objectively and critically.

Dispersive regime of circuit QED: photon-dependent qubit dephasing and relaxation rates

description: Superconducting electrical circuits can be used to study the physics of cavity quantum electrodynamics (QED) in new regimes, therefore realizing circuit QED. For quantum information processing and quantum optics, an interesting regime of circuit QED is the dispersive regime, where the detuning between the qubit transition frequency and the resonator frequency is much larger than the interaction strength. In this paper, we investigate how non-linear corrections to the dispersive regime affect the measurement process. We find that in the presence of pure qubit dephasing, photon population of the resonator used for the measurement of the qubit act as an effective heat bath, inducing incoherent relaxation and excitation of the qubit. Measurement thus induces both dephasing and mixing of the qubit, something that can reduce the quantum non-demolition aspect of the readout. Using quantum trajectory theory, we show that this heat bath can induce quantum jumps in the qubit state and reduce the achievable signal-to-noise ratio of a homodyne measurement of the voltage.

On Entropy Approximation for Gaussian Mixture Random Vectors
Creators: name: Huber, Marco F.
name: Bailey, Tim
name: Durrant-Whyte, Hugh
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2008

description: For many practical probability density representations such as for the widely used Gaussian mixture densities, an analytic evaluation of the differential entropy is not possible and thus, approximate calculations are inevitable. For this purpose, the first contribution of this paper deals with a novel entropy approximation method for Gaussian mixture random vectors, which is based on a component-wise Taylor-series expansion of the logarithm of a Gaussian mixture and on a splitting method of Gaussian mixture components. The employed order of the Taylor-series expansion and the number of components used for splitting allows balancing between accuracy and computational demand. The second contribution is the determination of meaningful and efficiently to calculate lower and upper bounds of the entropy, which can be also used for approximation purposes. In addition, a refinement method for the more important upper bound is proposed in order to approach the true entropy value.

Some aspects of buffering of acid soils of the Lower Fraser Valley
Creators: name: Wiens, John H.
Publisher: name: University of British Columbia
Year: 2011

description: A study was made to: i) determine the nature of acidity and buffering in acid soils of the Lower Fraser Valley of British Columbia, ii) evaluate and develop methods of predicting buffer capacities of these soils. Results of this study are described in a series of four papers, each describing different phases of this study. The Woodruff and Shoemaker, McLean and Pratt buffer methods proved to be unsuitable for use with these soils when compared to Ca(OH)₂ titration because the buffer pH depression was too small per unit lime requirement and there was considerable scatter about the regression calibration lime. Measurements of lime potential and corrected lime potential as well as pH were found to be significantly correlated with measures of exchangeable acidity but not with measures of pH-dependent acidity. The pH-dependent component of potential acidity was found to be highest for horizons highest in organic matter and in acid ammonium oxalate extractable Al and Fe. Regression equations derived for predicting buffer capacities explained the largest degree of variation of titrable acidity in the pH ranges below pH 5 and above pH 6. The model developed, combining these equations for prediction of buffer capacities to selected end pH values predicted buffer capacities as determined by a Ca(OH)₂ titration reasonably well. Comparison of NaOCl with H₂O₂ for oxidation of organic matter prior to acid ammonium oxalate extraction showed the former to be less destructive to sesquioxides, while at the same time as good or better for the oxidation of organic matter. Results of titrations of soils before and after oxalate extraction following treatment with NaOCl gave inconclusive results with respect to acidity due to the oxalate extractable component. This was due not to the method of removal of organic matter, however, but to uncertainties with respect to the nature of the exchange phase.
Direct Fusion of Dirac Mixture Densities using an Efficient Approximation in Joint State Space
Creators: name: Klumpp, Vesa
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2008

description: In this paper, we present a direct fusion algorithm for processing the combination of two Dirac mixture densities. The proposed approach allows the multiplication of two Dirac mixture densities without requiring identical support and thus enables the fusion of two independently generated sample sets. The resulting posterior Dirac mixture density is an approximation of the true continuous density that would result from the processing of the underlying true continuous density functions. This procedure is based on a suboptimal greedy approximation of the joint state space by means of a Dirac mixture that iteratively increases the resolution of the fusion result while considering only the relevant regions in the joint state space, where the fusion constraint holds.
The role of established voluntary neighbourhood groups in disseminating environmental information
Creators: name: McDonnell, Jennifer
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examines the role of voluntary established neighbourhood groups in the dissemination of environmental educational material. It used a participatory case study approach to involve eight neighbourhood groups in an education program disseminating information about wood-smoke pollution and how smoke could be minimised through correct woodheater operation. A primary goal of the program was to determine whether or not an environmental issue such as wood-smoke pollution could be linked in and 'piggybacked' on established groups which have other principal interests. An information kit about the problems associated with wood-smoke and clear steps that can be taken to reduce wood-smoke was prepared and given to eight neighbourhood groups in Hobart and Launceston, Tasmania. The information kit comprised of overheads for a seminar, an information booklet, and a pamphlet. The groups were asked to disseminate the information in any way they thought fit. The researcher acted as a facilitator and was available to participate in education efforts and provided support to the groups. The neighbourhood groups were surveyed to see what initiatives they took to distribute and promote the wood-smoke educational material. Observations were also made about the group processes within neighbourhood groups involved in the case study. The outcomes of the case study indicated that a considerable multiplier effect can occur by using established neighbourhood groups and their existing communication networks and interpersonal channels. The education activities carried out by the neighbourhood groups included public seminars on the topic of wood-smoke pollution, a door knocking campaign with wood-smoke pamphlets from the information kit, and education information was published in numerous newsletters. Overall the findings from the thesis indicate that established neighbourhood groups are willing to take environmental issues 'on-board' that are outside their principal interest. Observations of the groups that became more fully involved in the education program were encouraging, and a range of group characteristics were identified which would be useful to target suitable neighbourhood groups for future studies. Assessment of the information kit showed that the pamphlet and seminar materials were of high quality. A telephone survey conducted as part of the assessment of the case study activities revealed that council newsletters may have limited success as a means of disseminating information. This thesis has revealed that there are neighbourhood groups in the wider community that have established infrastructure, communication networks and channels that can benefit the distribution of environmental information. Supplying information to these groups on urban environmental issues such as the wood-smoke issue may provide a double benefit. Environmental education could be spread in an interpersonal manner and public interest and support for neighbourhood groups may increase.

In this paper, by presenting the mass-independent potentials of Kaluza--Klein (KK) modes in the corresponding Schrödinger equations, we investigate the localization and mass spectra of various bulk matter fields on the symmetric and asymmetric $dS$ thick branes. It is shown that the spectrum of scalar KK modes on the symmetric $dS$ brane contains only one bound mode (the massless mode). However, for the asymmetric $dS$ brane with a large asymmetric factor $a$, there are two bound scalar KK modes: a zero mode and a massive mode. For spin 1 vectors, the spectra of KK modes on both $dS$ branes consist of a bound massless mode and a set of continuous ones, i.e., the asymmetric factor does not change the number of the bound vector KK modes. For spin 1/2 fermions with the scalar-fermion coupling $η\barΨ\sin(ϕ/ϕ_0)\cos^{-δ}(ϕ/ϕ_0)Ψ$, there exist some discrete bound KK modes and a series of continuous ones. The asymmetric factor $a$ reduces the number of the bound fermion KK modes.

description: We show that in analogy to the introduction of Poisson structures twisted by a closed 3-form by Park and Klimcik-Strobl, the study of three dimensional sigma models with Wess-Zumino term leads in a likewise way to twisting of Courant algebroid structures by closed 4-forms H. The presentation is kept pedagogical and accessible to physicists as well as to mathematicians, explaining in detail in particular the interplay of field transformations in a sigma model with the type of geometrical structures induced on a target. In fact, as we also show, even if one does not know the mathematical concept of a Courant algebroid, the study of a rather general class of 3-dimensional sigma models leads one to that notion by itself. Courant algebroids became of relevance for mathematical physics lately from several perspectives - like for example by means of using generalized complex structures in String Theory. One may expect that their twisting by the curvature H of some 3-form Ramond-Ramond gauge field will become of relevance as well.

Critical comparison of retention models for use in computer aided interpretive optimisation of separation in anion chromatography
Creators: name: Madden, John
Publisher: name: University Of Tasmania
Year: 2023

description: This work deals with the optimisation of the eluent composition for the separation of anions using Ion Chromatography, specifically using an Iterative Interpretive Optimisation Strategy. Firstly a series of retention models is introduced that are suitable for use in an Interpretive Optimisation strategy. These models include the Linear Solvent Strength model (Dominant Equilibrium and Competing Ion Effective Charge Approaches), Hoover model, Dual Eluent Species model, Kuwamoto model, Extended Dual Eluent Species model, Multiple Species Eluent/Analyte model and the newly developed Empirical End Points model. Also included is the commercially available 3-point model of DryLab. The theory and mathematics behind these models are also discussed. These models have been critically compared to determine their suitability for use in an Iterative Interpretive Optimisation strategy. This comparison is broken into three parts, non-suppressed ion chromatography, suppressed ion chromatography, and single eluent species ion chromatography. For single eluent species ion chromatography the list of models was reduced to the Linear Solvent Strength model, the Empirical End Points model and the 3-point model of DryLab, which were found to be the only models suitable for this type of chromatography. The 3-point model of DryLab was found to be unsuitable for multiple species eluent ion chromatography. A number of trends were noted across the comparison, the most significant of which were that the Empirical End Points and Linear Solvent Strength models were the only two models that were applicable to the entire data set. The Empirical End Points model was consistently the best performed model while the Linear Solvent Strength model was consistently the worst, and the solution requirements for the Empirical End Points model were found to be the most suitable for an optimisation process. Thus the Empirical End Points model was chosen as the retention model for the optimisation process. Next, a procedure for an Iterative Interpretive Optimisation process was developed and a computer program written to handle the large number of calculations required for the process. The computer program was for the Iterative Interpretive Optimisation process of the eluent concentration only. A case study using a carbonate eluent was conducted to test the program and procedure, resulting in the separation of 20 anions within 12 minutes. Finally, the use of an Artificial Neural Network as a retention model was studied. Artificial Neural Networks were found to require a large amount of training compared with theoretical retention models, but their high level of accuracy and low system knowledge requirements make them a prospect worthy of further evaluation.

description: Frequent transitions between core clinical rotations in medical school increase anxiety and cognitive load. Few formalized programs exist to ease these transitions. Our institutional needs-assessment found that approximately 85% of students believed that additional rotation-specific information prior to starting a new rotation would reduce anxiety and increase success. We developed a novel web-based peer-to-peer handoff tool available to all clerkship students at a single, large academic institution. The tool contains the names and contact information of students who most recently completed rotations on each service for all clerkships. A handoff checklist was also created with suggested discussion points for handoffs. Students were encouraged to schedule a handoff 1-2 weeks before starting a new rotation. Overall, 83 students (66%) utilized the handoff tool, with use and efficacy decreasing with time during the clinical year. Of tool users, 65% expressed that having access to the tool prior to starting a new rotation helped to reduce anxiety, and 74% felt that the information gained helped to ease transitions. Our peer-to-peer handoff tool may help students feel more prepared to start a new rotation, decrease anxiety during clerkship year, and ease transitions. This low-resource intervention may be implemented at other institutions to provide students with equal opportunities to receive valuable information prior to starting new rotations, regardless of pre-existing peer connections. An automated update system, which we are implementing at our institution, could greatly decrease the time required to maintain a handoff tool and improve sustainability.

description: We prove that the relative K-groups associated with a nilpotent extension of Z/p^N Z-algebras and the bi-relative K-groups associated with a Milnor square of Z/p^N Z-algebras are p-primary torsion groups of bounded exponent. We also show that, in general, the cyclotomic trace map extends from Quillen K-theory to Bass completed non-connective algebraic K-theory.

Dirac Mixture Trees for Fast Suboptimal Multi-Dimensional Density Approximation
Creators: name: Klumpp, Vesa

Publisher: name: Karlsruhe
Year: 2008

description: We consider the problem of approximating an arbitrary multi-dimensional probability density function by means of a Dirac mixture density. Instead of an optimal solution based on minimizing a global distance measure between the true density and its approximation, a fast suboptimal anytime procedure is proposed, which is based on sequentially partitioning the state space and component placement by local optimization. The proposed procedure adaptively covers the entire state space with a gradually increasing resolution. It can be efficiently implemented by means of a pre-allocated tree structure in a straightforward manner. The resulting computational complexity is linear in the number of components and linear in the number of dimensions. This allows a large number of components to be handled, which is especially useful in high-dimensional state spaces.

description: We study critical properties of the relaxation time at a threshold point in switching processes between bistable states under change of external fields. In particular, we investigate the relaxation processes near the spinodal point of the infinitely long-range interaction model (the Husimi-Temperley model) by analyzing the scaling properties of the corresponding Fokker-Planck equation. We also confirm the obtained scaling relations by direct numerical solution of the original master equation, and by kinetic Monte Carlo simulation of the stochastic decay process. In particular, we study the asymptotic forms of the divergence of the relaxation time near the spinodal point, and reexamine its scaling properties. We further extend the analysis to transient critical phenomena such as a threshold behavior with diverging switching time under a general external driving perturbation. This models photo-excitation processes in spin-crossover materials. In the ongoing development of nano-size fabrication, such size-dependence of switching processes should be an important issue, and the properties obtained here will be applicable to a wide range of physical processes.
