A case study of the induction experience of new teachers in one Catholic primary school
Creators: name: Thornton, Rhonda
Publisher: name: Australian Catholic University
Year: 1996

description: Many principals, as leaders in Catholic schools today, are concerned with building a strong school culture based on the common belief of Jesus Christ. Induction of new teachers into the school influences this culture as they bring with them a diversity of beliefs, experience, attitude, and professional maturity. The challenge principals, as leaders, face is continually renewing the shared vision of the community, and maintaining a balance between the corporate needs and those of individuals. The literature suggests that in building a strong culture of a school, a principal must engage in leadership which empowers others to see meaning in what they do, and share in the vision of the community. Building a strong school culture with a shared vision, requires a commitment to renewal. Induction, as an interrelated component of staff development, provides an opportunity for renewal of both school and individual goals. The purpose of the study is to investigate the experience of a formal induction program in one Catholic primary school. From this experience, the researcher endeavoured to develop a "rich picture" (Patching, 1990) of induction, which in turn, would inform the formulation of a set of guiding principles for future induction programs. A process of reflective deliberation (Bonser & Grundy, 1988) has enabled a rich picture to be gathered, as practitioners reflected on their recent experience of induction within one Catholic primary school. This methodology of action research, with its "moments" of planning, acting, and reflecting, was most suitable for involving practitioners in bringing about change. The research highlights some key insights into what are considered as important issues to focus on during induction. They are: telling the story of a culture rooted in beliefs and values; creating a relational climate; and professional development which recognises, cultivates, and respects differing values. Recommendations made by participants became guiding principles for the planning of future induction programs in the school, and these strengthened the argument of the need for openness to differences rather than the urge towards sameness (Nicholson, 1991).
Quasar Microlensing at High Magnification and the Role of Dark Matter: Enhanced Fluctuations and Suppressed Saddlepoints

description: Contrary to naive expectation, diluting the stellar component of the lensing galaxy in a highly magnified system with smoothly distributed ``dark'' matter increases rather than decreases the microlensing fluctuations caused by the remaining stars. For a bright pair of images straddling a critical curve, the saddlepoint (of the arrival time surface) is much more strongly affected than the associated minimum. With a mass ratio of smooth matter to microlensing matter of 4:1, a saddlepoint with a macro-magnification of mu = 9.5 will spend half of its time more than a magnitude fainter than predicted. The anomalous flux ratio observed for the close pair of images in MG0414+0534 is a factor of five more likely than computed by Witt, Mao and Schechter if the smooth matter fraction is as high as 93%. The magnification probability histograms for macro-images exhibit distinctly different structure that varies with the smooth matter content, providing a handle on the smooth matter fraction. Enhanced fluctuations can manifest themselves either in the temporal variations of a lightcurve or as flux ratio anomalies in a single epoch snapshot of a multiply imaged system. While the millilensing simulations of Metcalf and Madau also give larger anomalies for saddlepoints than for minima, the effect appears to be less dramatic for extended subhalos than for point masses. Morever, microlensing is distinguishable from millilensing because it will produce noticeable changes in the magnification on a time scale of a decade or less.

description: Efficiency in passage times is an important issue in designing networks, such as transportation or computer networks. The small-world networks have structures that yield high efficiency, while keeping the network highly clustered. We show that among all networks with the small-world structure, the most efficient ones have a single ``center'', from which all shortcuts are connected to uniformly distributed nodes over the network. The networks with several centers and a connected subnetwork of shortcuts are shown to be ``almost'' as efficient. Genetic-algorithm simulations further support our results.

description: Simulations of gauge theories on quantum computers require the digitization of continuous field variables. Digitization schemes that uses the minimum amount of qubits are desirable. We present a practical scheme for digitizing $SU(3)$ gauge theories via its discrete subgroup $S(1080)$. The $S(1080)$ standard Wilson action cannot be used since a phase transition occurs as the coupling is decreased, well before the scaling regime. We proposed a modified action that allows simulations in the scaling window and carry out classical Monte Carlo calculations down to lattice spacings of order $a\approx 0.08$ fm. We compute a set of observables with sub-percent precision at multiple lattice spacings and show that the continuum extrapolated value agrees with the full $SU(3)$ results. This suggests that this digitization scheme provides sufficient precision for NISQ-era QCD simulations.

description: We discuss graded D-brane systems of the topological A model on a Calabi-Yau threefold, by means of their string field theory. We give a detailed analysis of the extended string field action, showing that it satisfies the classical master equation, and construct the associated BV system. The analysis is entirely general and it applies to any collection of D-branes (of distinct grades) wrapping the same special Lagrangian cycle, being valid in arbitrary topology. Our discussion employs a $\Z$-graded version of the covariant BV formalism, whose formulation involves the concept of {\em graded supermanifolds}. We discuss this formalism in detail and explain why $\Z$-graded supermanifolds are necessary for a correct geometric understanding of BV systems. For the particular case of graded D-brane pairs, we also give a direct construction of the master action, finding complete agreement with the abstract formalism. We analyze formation of acyclic composites and show that, under certain topological assumptions,all states resulting from the condensation process of a pair of branes with grades differing by one unit are BRST trivial and thus the composite can be viewed as a closed string vacuum. We prove that there are {\em six} types of pairs which must be viewed as generally inequivalent. This contradicts the assumption that `brane-antibrane' systems exhaust the nontrivial dynamics of topological A-branes with the same geometric support.

description: We introduce the filtered *-bialgebra which is a noncommutative analog of the *-bialgebra of multivariate polynomials with the canonical coproduct and counit. We study the associated filtered convolutions, random walks and random variables. The GNS representations of the limit states lead to filtered fundamental operators which are the CCR fundamental operators on the multiple symmetric Fock space, multiplied by appropriate projections. The importance of filtered random variables and fundamental operators stems from the fact that by addition and strong limits one obtains from them the main types of noncommutative random variables and fundamental operators, respectively, regardless of the type of noncommutative independence.

description: We have developed a novel detector, referred to as an "$α$-ToF detector", for correlated measurements of atomic masses and decay properties of low-yield, short-lived radioactive isotopes using a multi-reflection time-of-flight mass spectrograph. By correlating measured time-of-flight signals with decay events, it will be possible to suppress background events and obtain accurate, high-precision mass values even in cases of very low event rates. An offline test of the $α$-ToF detector has shown that the time-of-flight detection efficiency for 5.48~MeV $α$-rays is more than 90\% and yields a time resolution of 251.5(68)~ps and an energy resolution of 141.1(9)~keV. Using a two-dimensional spectrum of the correlated $α$-ray energy and time-of-flight, the $α$-rays from mixed $α$ sources could be fairly well resolved.

description: We implement a computer-assisted approach that, under appropriate conditions, allows the bifurcation analysis of the coarse dynamic behavior of microscopic simulators without requiring the explicit derivation of closed macroscopic equations for this behavior. The approach is inspired by the so-called time-step per based numerical bifurcation theory. We illustrate the approach through the computation of both stable and unstable coarsely invariant states for Kinetic Monte Carlo models of three simple surface reaction schemes. We quantify the linearized stability of these coarsely invariant states, perform pseudo-arclength continuation, detect coarse limit point and coarse Hopf bifurcations and construct two-parameter bifurcation diagrams.

description: We present VR observations of QSO 2237+0305 conducted by the GLITP collaboration from 1999 October 1 to 2000 February 3. The observations were made with the 2.56 m Nordic Optical Telescope at Roque de los Muchachos Observatory, La Palma (Spain). The PSF fitting method and an adapted version of the ISIS subtraction method have been used to derive the VR light curves of the four components (A-D) of the quasar. The mean errors range in the intervals 0.01-0.04 mag (PSF fitting) and 0.01-0.02 mag (ISIS subtraction), with the faintest component (D) having the largest uncertainties. We address the relatively good agreement between the A-D light curves derived using different filters, photometric techniques, and telescopes. The new VR light curves of component A extend the time coverage of a high magnification microlensing peak, which was discovered by the OGLE team.

description: In this article we introduce a body of research on drawing in the extended field and discuss a recent outcome – Reef, an installation at the Tin Shed gallery, Sydney. The research agenda has evolved from architectural sketch drawing, where rapidly drawn marks capture evocative presences yet are also coded, analytical, and need to be read. Lines refer to scale, form and materials in space beyond them, at the same time as recording the authors’ imaginative projection into those worlds. The research extends the open, evocative capacity of drawing to installation art works, of which Reef is the second in a series exploring the landscape phenomena of seismic shock.
Reef is an experimental installation that exists simultaneously in three overlapping dimensions: material space, virtual space and sound space. It is a sketch of a small section of seabed in Kaikōura, Aotearoa New Zealand. The Kaikōura reef is the visible part of a vast landscape that drops several kilometres below the sea’s surface and connects to an extensive canyon system that marks the junction of the pacific and Australian tectonic plates. Vast forces were released in the 2016 Kaikōura earthquake causing the submarine landscape to jolt upwards, and with it the reef.
This project uses a hybrid of cast concrete miniature sketches, sound sketches and sketches in VR and AR to capture the ambiguous scale and strange presence of this landscape. Visitors to the gallery are immersed in a single spatial sketch, composed of a cloud of elements that operate as grains of graphite in a rapidly sketched mark. These are an array that morphs from castings of the rock surface to gestural concrete sketches to digital interpretations. The reading of these sketches is augmented by overlapping soundscapes and images from a virtual sketch environment, creating a multi-sensory 3-dimensional drawing that surrounds the participant. The Reef installation highlights shifts in notions of drawing and its research agency.
Kovalevski exponents and integrability properties in class A homogeneous cosmological models

description: Qualitative approach to homogeneous anisotropic Bianchi class A models in terms of dynamical systems reveals a hierarchy of invariant manifolds. By calculating the Kovalevski Exponents according to Adler - van Moerbecke method we discuss how algebraic integrability property is distributed in this class of models. In particular we find that algebraic nonintegrability of vacuum Bianchi VII_0 model is inherited by more general Bianchi VIII and Bianchi IX vacuum types. Matter terms (cosmological constant, dust and radiation) in the Einstein equations typically generate irrational or complex Kovalevski exponents in class A homogeneous models thus introducing an element of nonintegrability even though the respective vacuum models are integrable.

Dimerization and effective decoupling in two spin-1 generalizations of the spin-1/2 Majumdar-Ghosh chain

Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We perform a systematic DMRG investigation of the two natural spin-1 generalizations of the spin-1/2 Majumdar-Ghosh chain, the spin-1 $J_1-J_2$ Heisenberg chain, where $J_2$ is a next-nearest neighbor Heisenberg coupling, and the spin-1 $J_1-J_3$ model, where $J_3$ refers to a three-site interaction defined by $J_3\left[({\bf S}_{i-1}\cdot {\bf S}_i)({\bf S}_i\cdot {\bf S}_{i+1})+\mathrm {H.c.}\right]$. Although both models are rigorously equivalent to the Majumdar-Ghosh chain for spin-1/2, their physics appears to be quite different for spin 1. Indeed, when all couplings are antiferromagnetic, the spin-1 $J_1-J_2$ model undergoes an effective decoupling into two next-nearest neighbour (NNN) Haldane chains upon increasing $J_2$, while the $J_1-J_3$ chain undergoes a spontaneous dimerization similar to the spin-1/2 Majumdar-Ghosh chain upon increasing $J_3$. By extending the phase diagram to all signs of the couplings, we show that both the dimerized and the NNN-Haldane phase are actually present in the $J_1-J_3$ model, the former one adjacent to the Haldane one, the latter one to the ferromagneric one, with an Ising transition between them. By contrast, the $J_1-J_2$ chain only has a NNN-Haldane phase between the Haldane phase and the ferromagnetic phase for positive $J_2$. In both cases, our DMRG data are consistent with a continuous Kosterlitz-Thouless transition between the NNN-Haldane and the ferromagnetic phases.

description: We present imaging and spectroscopic observations of 6478 Gault, a 6 km diameter inner main-belt asteroid currently exhibiting strong, comet-like characteristics. Three distinct tails indicate that ultra-slow dust (ejection speed 0.15+/-0.05 m/s) was emitted from Gault in separate episodes beginning UT 2018 October 28+/-5 (Tail A), UT 2018 December 31+/-5 (Tail B), and UT 2019 February 10+/-7, with durations of 10 to 20 days. With a mean particle radius 100 micron, the estimated masses of the tails are M_A = 2e7 kg, M_B = 3e6 kg and M_C = 3e5 kg, respectively, and the mass loss rates from the nucleus are 10 to 20 kg/s for Tail A, 2 to 3 kg/s for Tail B and about 0.2 kg/s for Tail C. In its optical colors Gault is more similar to C-type asteroids than to S-types, even though the latter are numerically dominant in the inner asteroid belt. A spectroscopic upper limit to the production of gas is set at 1 kg/s. Discrete emission in three protracted episodes effectively rules out an impact origin for the observed activity. Sublimation driven activity is unlikely given the inner belt orbit and the absence of detectable gas. In any case, sublimation would not easily account for the observed multiple ejections. The closest similarity is between Gault and active asteroid 311P/(2013 P5), an object showing repeated but aperiodic ejections of dust over a 9 month period. While Gault is 10 times larger than 311P/(2013 P5), and the spin-up time to radiation torques is 100 times longer, its properties are likewise most consistent with episodic emission from a body rotating near breakup.

description: Large scale natural phenomena such as earthquakes, storms and bushfire hover at the edge of human perception and appear almost sentient in their capacity to shape-shift and morph, as they envelop terrains and evade human’s urgent responses. Sophisticated scientific modelling and analysis is able to rationalise such phenomena, but it doesn’t capture their almost-human dynamics. We explore this hybrid space of phenomena, as a strange coalescence of material performances and human affective and imaginative registers.

The work is grounded in spatial practices of drawing, focussing on the architectural sketch. The sketch’s open, ‘non-totalizing’ capacity (Nancy, 2013: 1), to draw impressions of space without fully fixing them, is directed toward natural phenomena. We expand the irresolute capacity of the sketch through installations composed of sculptural objects, virtual environments and spatial sound. These are used to capture phenomena as an anthropo-natural hybrid space, blending human imagination, technology, matter and other-than-human forces: In these installations, spatial ‘blurrings’ map to the imagination of ungraspable, peripheral characteristics in phenomena.

To date two mixed-media installations have explored this agenda, drawing presences from the geology and dramatic seismic activity of Aotearoa New Zealand. These operate as immersive drawings, prompting visceral witnessing of open, unfixed, sketched phenomena. We reflect on this previous work and present a work-in-progress: a sketch of large-scale bushfire phenomena. The key concept that informs the work is sympoiēsis, or ‘making together’, a way to re-think the entangled relations between human and other-than-human actants (Harraway, 2016:4). The expanded sketch gives us a way of merging artistic research practices, where the agency of matter – material and digital - ties to thought. In our creative practice, we are interested in how matter pushes back, how sketches can be sympoiētic, ‘made together’ by human thought and action in concert with other-than human forces.

description: State-of-the-art approaches for clustering high-dimensional data utilize deep auto-encoder architectures. Many of these networks require a large number of parameters and suffer from a lack of interpretability, due to the black-box nature of the auto-encoders. We introduce Mixture Model Auto-Encoders (MixMate), a novel architecture that clusters data by performing inference on a generative model. Derived from the perspective of sparse dictionary learning and mixture models, MixMate comprises several auto-encoders, each tasked with reconstructing data in a distinct cluster, while enforcing sparsity in the latent space. Through experiments on various image datasets, we show that MixMate achieves competitive performance compared to state-of-the-art deep clustering algorithms, while using orders of magnitude fewer parameters.

description: Our paper reflects on three recent projects employing multi-modal architectural drawing to sketch natural phenomena: Canyon, Reef, and Bush fire. The work explores aleatory, intangible conditions within natural phenomena, conditions at the cusp of awareness, spatially felt as much as known by other means. Through multi-sensory drawing installations, phenomena such as oceanic immensity, seismic latency and shapeshifting bushfires are sketched. The drawing installations immerse participants in an array of sculptural, virtual, and sonic sketches, causing the sketches of phenomena to be ‘inhabitable’ as dynamic, drawn worlds.
The sketches begin with rapidly drawn, smudged, graphite marks, proceeding to three-dimensional, gestural acts of sketching, through manipulating castings of rock, latex, wax and concrete. These are interpreted through digital software and new drawings created algorithmically, populating an immersive virtual environment entirely composed of irresolute, abstract, sketched marks. In the gallery space, the gestural concrete sketches are arrayed as a cloud of miniature sculptural objects. Moving through this is akin to walking through the pixels, or graphite grains, in a single sketch, following currents and eddies in its ideation. The sketch also has zones of sound, with overlapping three-dimensional ‘sound sketches’ creating an abstract accompaniment to the shifts and changes in the cloud of cast objects, inflecting and jolting the reading of the sketch. Soundscapes also occur in the parallel VR and AR sketch environments which provide portals to a dynamic and shifting abstract sketch-space.
The sketches in Expanded Drawing seek to resist fixity of thought and conclusion through expanding the sketch’s power to be ‘open’ through “an essential incompleteness, a non-closure or non-totalizing of form” (Nancy, 2013: 1). The work also expands the gestural characteristics of the architectural sketch, intensifying it as a mode of architectural thought involving “knowing-thinking-feeling” (Gansterer et al, 2017: 9). This research by creative practice develops techniques to extend the sketch as a way of capturing unfixed, intangible presences between drawer, sketch medium and imagined space. The work is beginning to coalesce a strange spatiality—the complex terrain flowing between drawing’s matter, its subject matter, and human gesture and imagination is gradually emerging as a sketch-like hybrid space.

 Neu für Österreich. H. fastuosum, ein sehr seltener Endemit der Ostalpen, war bisher nur aus Südtirol (Pfossental, Mühlwaldtal u. Staller Sattel), dem Trentino (Monte Ziolera) und aus Friaul-Julisch-Venetien (Karnische Alpen) bekannt (vgl. ZAHN 1937: 418, GOTTSCHLICH 2001: 584, 2004: 134 (Abb.), 146, 2007: 62, 194/195 (Abb. Lectotypus), 2008a: 18, 2008b: 1013, GOTTSCHLICH & PUJATTI 2002: 301 u. WILHALM et al. 2006: 99). Die in ZAHN (1906: 664 f.) für die Schweiz unter H. fastuosum angeführte Subspezies trichopicris wurde von ihm in seiner monographischen Bearbeitung für "Das Pflanzenreich" (ZAHN 1921: 851) zu H. picroides gezogen.
Die fünf herbarisierten Pflanzen vom Rotgüldensee entsprechen im wesentlichen dem Merkmalsspektrum des Typenmaterials im Herbarium Huter (BRIX), das der Verfasser dankenswerterweise über W. Neuner (Herbarium IBF) entlehnen konnte.

description: We investigate the role weakly damped modes play in the selection of Faraday wave patterns forced with rationally-related frequency components m*omega and n*omega. We use symmetry considerations to argue for the special importance of the weakly damped modes oscillating with twice the frequency of the critical mode, and those oscillating primarily with the "difference frequency" |n-m|*omega and the "sum frequency" (n+m)*omega. We then perform a weakly nonlinear analysis using equations of Zhang and Vinals (1997, J. Fluid Mech. 336) which apply to small-amplitude waves on weakly inviscid, semi-infinite fluid layers. For weak damping and forcing and one-dimensional waves, we perform a perturbation expansion through fourth order which yields analytical expressions for onset parameters and the cubic bifurcation coefficient that determines wave amplitude as a function of forcing near onset. For stronger damping and forcing we numerically compute these same parameters, as well as the cubic cross-coupling coefficient for competing waves travelling at an angle theta relative to each other. The resonance effects predicted by symmetry are borne out in the perturbation results for one spatial dimension, and are supported by the numerical results in two dimensions. The difference frequency resonance plays a key role in stabilizing superlattice patterns of the SL-I type observed by Kudrolli, Pier and Gollub (1998, Physica D 123).

description: We explore two methods for single crystal growth of the theoretically proposed magnetic Weyl semimetals $R$AlGe ($R$ = Pr,Ce), which prove that a floating zone technique, being both crucible- and flux-free, is crucial to obtain perfectly stoichiometric $R$AlGe crystals. In contrast, the crystals grown by a flux growth technique tend to be Al-rich. We further present both structural and elemental analysis, along with bulk magnetization and electrical resistivity data on the crystals prepared by the floating zone technique. Both systems with the intended 1:1:1 stoichiometry crystallize in the anticipated polar I4$_{1}$md (No. 109) space group, although neither displays the theoretically expected ferromagnetic ground state. Instead PrAlGe displays a spin-glass-like transition below 16 K with an easy-c-axis and CeAlGe has an easy-ab-plane antiferromagnetic order below 5 K. The grown crystals provide an ideal platform for microscopic studies of the magnetic field-tunable correlation physics involving magnetism and topological Weyl nodes.

description: We report here on the observation of Kes 27, a proto-typical mixed-morphology SNR, using ASCA. It clearly shows a filled-center structure in the X-ray region while a shell structure in the radio region. There are two radio bright regions: one is in the center, while the other is in the east rim. The X-ray intensity peak coincides well with the radio bright region at the center. The X-ray spectrum was well-fitted by a collisional ionization equilibrium model with solar abundances. Taking into account the ionization parameter (>10^{12} cm^{-3} s) and the plasma density (0.39 cm^{-3}), we found that the age of the SNR is longer than 8x10^4 yr. The hardness ratio map indicates that the inner region shows a harder spectrum than that in the outer region, which does not come from the heavier interstellar absorption feature, but from the higher temperature. There is a temperature gradient from the innner region (0.84 keV) toward outer region (0.59 keV), indicating that the thermal conduction does not play an important role.

description: Dynamical tunneling has been observed in atom optics experiments by two groups. We show that the experimental results are extremely well described by time-periodic Hamiltonians with momentum quantized in units of the atomic recoil. The observed tunneling has a well defined period when only two Floquet states dominate the dynamics. Beat frequencies are observed when three Floquet states dominate. We find frequencies which match those observed in both experiments. The dynamical origin of the dominant Floquet states is identified.

description: It was found that s-wave scattering of chiral fermion off dilaton black-hole when studied with a model generated from the chiral Schwinger model with standard Jackiw-Rajaraman type of anomaly provided information non preserving result. However this scattering problem when studied with a model generated from chiral Schwinger model with generalized Faddeevian type of anomaly. rendered information preserving result and it had well agreement with Hawking's revised proposal related to information loss. A minute and equitable investigation in detail has been carried out here to show how Faddeevian type of anomaly scores over the Jackiw-Rajaraman type of anomaly in connection with the s-wave scattering of chiral fermion of dilaton black-hole related to preservation of information.

description: In this article we perform the quantization of graphene plasmons using both a macroscopic approach based on the classical average electromagnetic energy and a quantum hydrodynamic model, in which graphene charge carriers are modeled as a charged fluid. Both models allow to take into account the dispersion of graphenes optical response, with the hydrodynamic model also allowing for the inclusion of non-local effects. Using both methods, the electromagnetic field mode-functions, and the respective frequencies, are determined for two different graphene structures. we show how to quantize graphene plasmons, considering that graphene is a dispersive medium, and taking into account both local and nonlocal descriptions. It is found that the dispersion of graphene's optical response leads to a non-trivial normalization condition for the mode-functions. The obtained mode-functions are then used to calculate the decay of an emitter, represented by a dipole, via the excitation of graphene surface plasmon-polaritons. The obtained results are compared with the total spontaneous decay rate of the emitter and a near perfect match is found in the relevant spectral range. It is found that non-local effects in graphene's conductivity, become relevant for the emission rate for small Fermi energies and small distances between the dipole and the graphene sheet.

description: The Submillimetre Common User Bolometer Array (SCUBA) instrument has been operating on the James Clerk Maxwell Telescope (JCMT) since 1997. The data archive is now sufficiently large that it can be used to investigate instrumental properties and the variability of astronomical sources. This paper describes the automated calibration and reduction scheme used to process the archive data with particular emphasis on `jiggle-map' observations of compact sources. We demonstrate the validity of our automated approach at both 850- and 450-microns and apply it to several of the JCMT secondary flux calibrators. We determine light curves for the variable sources IRC+10216 and OH231.8. This automation is made possible by using the ORAC-DR data reduction pipeline, a flexible and extensible data reduction pipeline that is used on UKIRT and the JCMT.

description: Iterated functions system (IFS) is defined by specifying a set of functions in a classical phase space, which act randomly on an initial point. In an analogous way, we define a quantum iterated functions system (QIFS), where functions act randomly with prescribed probabilities in the Hilbert space. In a more general setting a QIFS consists of completely positive maps acting in the space of density operators. We present exemplary classical IFSs, the invariant measure of which exhibits fractal structure, and study properties of the corresponding QIFSs and their invariant states.

"Dispersion management" for solitons in a Korteweg-de Vries system

description: The existence of ``dispersion-managed solitons'', i.e., stable pulsating solitary-wave solutions to the nonlinear Schrödinger equation with periodically modulated and sign-variable dispersion is now well known in nonlinear optics. Our purpose here is to investigate whether similar structures exist for other well-known nonlinear wave models. Hence, here we consider as a basic model the variable-coefficient Korteweg-de Vries equation; this has the form of a Korteweg-de Vries equation with a periodically varying third-order dispersion coefficient, that can take both positive and negative values. More generally, this model may be extended to include fifth-order dispersion. Such models may describe, for instance, periodically modulated waveguides for long gravity-capillary waves. We develop an analytical approximation for solitary waves in the weakly nonlinear case, from which it is possible to obtain a reduction to a relatively simple integral equation, which is readily solved numerically. Then, we describe some systematic direct simulations of the full equation, which use the soliton shape produced by the integral equation as an initial condition. These simulations reveal regions of stable and unstable pulsating solitary waves in the corresponding parametric space. Finally, we consider the effects of fifth-order dispersion.
