Bifurcation analysis of a normal form for excitable media: Are stable dynamical alternans on a ring possible?

description: We present a bifurcation analysis of a normal form for travelling waves in one-dimensional excitable media. The normal form which has been recently proposed on phenomenological grounds is given in form of a differential delay equation. The normal form exhibits a symmetry preserving Hopf bifurcation which may coalesce with a saddle-node in a Bogdanov-Takens point, and a symmetry breaking spatially inhomogeneous pitchfork bifurcation. We study here the Hopf bifurcation for the propagation of a single pulse in a ring by means of a center manifold reduction, and for a wave train by means of a multiscale analysis leading to a real Ginzburg-Landau equation as the corresponding amplitude equation. Both, the center manifold reduction and the multiscale analysis show that the Hopf bifurcation is always subcritical independent of the parameters. This may have links to cardiac alternans which have so far been believed to be stable oscillations emanating from a supercritical bifurcation. We discuss the implications for cardiac alternans and revisit the instability in some excitable media where the oscillations had been believed to be stable. In particular, we show that our condition for the onset of the Hopf bifurcation coincides with the well known restitution condition for cardiac alternans.

Political appeal of an ambiguous idea: explaining the institutionalisation of food sovereignty in Nepal
Creators: name: Sharma, Puspa
Publisher: name: The Australian National University
Year: 2019

description: The idea of food sovereignty lacks clarity and is imprecise. Yet, some countries have accepted the idea and included it in their constitutions and legislation. Existing literature on food sovereignty tends to argue that the reason for the institutionalisation of the idea of food sovereignty by some countries is that these countries have accepted the demands made by social movements on food sovereignty and are willing to make changes in the food and agriculture sector accordingly. I argue that this explanation regarding the institutionalisation of the idea of food sovereignty does not hold much ground. Rather, the institutionalisation of the idea of food sovereignty can be better explained by the "coalition magnet" thesis. A coalition magnet is an idea with political appeal that attracts a diversity of individuals and groups, and is used strategically by policy entrepreneurs to frame their interests, mobilise supporters and build coalitions. For an idea to be called a coalition magnet, three things are essential: 1) effective manipulation of the idea by policy entrepreneurs, 2) embracing or promotion of the idea by key actors in the policy process, and 3) coming together of actors who previously seemed to be at odds. I find that the idea of food sovereignty possesses these three attributes, and this helps explain the institutionalisation of food sovereignty by Nepal. In Nepal, there were policy entrepreneurs who propagated the idea of food sovereignty, and other actors also found the idea appealing, more so because they could interpret and accept the idea of food sovereignty in their own particular ways. This facilitated agenda setting as can be seen in the inclusion of "food sovereignty" in Nepal's Constitution, and also in relevant policy and planning documents. However, the incorporation of the idea of food sovereignty in these official documents has been vague and imprecise. In terms of operationalising the idea of food sovereignty, there has not been much progress. This shows that ideas that are coalition magnets could be useful for agenda setting. But the nature of a coalition magnet also explains why the idea might be difficult to implement.
Coating maintenance optimization for steel penstocks
Creators: name: Siu, Milton
Publisher: name: University of British Columbia
Year: 2009

description: Two methods for minimizing coating maintenance costs for steel penstocks are presented in this thesis. The first method performs a life-cycle cost analysis using equivalent annual costs to compare the three maintenance strategies: touch-up, overcoat, and, strip and recoat. The strategy with the lowest annual costs is considered to be optimal. The second method uses a dynamic programming approach to obtain the minimum costs resulting from a sequence of rehabilitation choices. A computer application, Penstock Maintenance Program (PMP), was developed based on the two optimization procedures. It was intended for this program to serve as a practical tool to minimize the yearly costs of penstock coating maintenance. The program was therefore developed on a platform which is both accessible and familiar. An on-line help feature has also been provided to ease the use of the program. In addition to performing the two optimization procedures, PMP allows the user to enter trial sequences of rehabilitation strategies to compare equivalent annual costs. Interval calculations have also been implemented to handle imprecisely defined cost data.

description: In this paper, the unified gas-kinetic wave-particle (UGKWP) method is further developed for diatomic gas with the energy exchange between translational and rotational modes for flow study in all regimes. The multiscale transport mechanism in UGKWP is coming from the direct modeling in a discretized space, where the cell's Knudsen number, defined by the ratio of particle mean free path over the numerical cell size, determines the flow physics simulated by the wave particle formulation. The non-equilibrium distribution function in UGKWP is tracked by the discrete particle and analytical wave. The weights of distributed particle and wave in different regimes are controlled by the accumulating evolution solution of particle transport and collision within a time step, where distinguishable macroscopic flow variables of particle and wave are updated inside each control volume. With the variation of local cell's Knudsen number, the UGKWP becomes a particle method in the highly rarefied flow regime and converges to the gas-kinetic scheme (GKS) for the Navier-Stokes solution in the continuum flow regime without particles. Even targeting on the same solution as the discrete velocity method (DVM)-based unified gas-kinetic scheme (UGKS), the computational cost and memory requirement in UGKWP could be reduced by several orders of magnitude for the high speed and high temperature flow simulation, where the translational and rotational non-equilibrium becomes important in the transition and rarefied regime. As a result, 3D hypersonic computations around a flying vehicle in all regimes can be conducted using a personal computer. The UGKWP method for diatomic gas will be validated in various cases from one dimensional shock structure to three dimensional flow over a sphere, and the numerical solutions will be compared with the reference DSMC results and experimental measurements.

description: We explore numerically the synchronization effects in a heterogeneous two-layer network of two-dimensional (2D) lattices of van der Pol oscillators.The inter-layer coupling of the multiplex network has an attractive character. One layer of 2D lattices is characterized by attractive coupling of oscillators and demonstrates a spiral wave regime for both the local and nonlocal interaction. The oscillators in the second layer are coupled through active elements and the interaction between them has the repulsive character. We show that the lattice with the repulsive type of coupling demonstrates complex spatiotemporal cluster structures, which can be called as labyrinth-like structures. We show for the first time that this multiplex network with fundamentally different types of intra-layer coupling demonstrates the mutual synchronization and a competition between two types of structures. Our numerical study indicates that the synchronization threshold and the type of spatiotemporal patterns in both the layers strongly depend on the ratio of the intra-layer coupling strength of the two lattices. We also analyze the impact of intra-layer coupling ranges on the synchronization effects.

description: It has, quite recently, become fashionable to study a certain class of holographic-inspired models for the dark energy. These investigations have, indeed, managed to make some significant advances towards explaining the empirical data. Nonetheless, surprisingly little thought has been given to conceptual issues such as the composition and the very nature of the implicated energy source. In the current discourse, we attempt to fill this gap by the way of some speculative yet logically self-consistent arguments. Our construction takes us along a path that begins with an entanglement entropy and ends up at a Hubble-sized gas of exotic particles. Moreover, our interpretation of the dark energy turns out to be suggestive of a natural resolution to the cosmic-coincidence problem.

description: Coherent macroscopic tunneling of a Bose-Einstein condensate between two parts of an optical lattice separated by an energy barrier is theoretically investigated. We show that by a pulsewise change of the barrier height, it is possible to switch between tunneling regime and a self-trapped state of the condensate. This property of the system is explained by effectively reducing the dynamics to the nonlinear problem of a particle moving in a double square well potential. The analysis is made for both attractive and repulsive interatomic forces, and it highlights the experimental relevance of our findings.
Almost uniform sampling via quantum walks

Publisher: name: arXiv
Year: 2006

description: Many classical randomized algorithms (e.g., approximation algorithms for #P-complete problems) utilize the following random walk algorithm for {\em almost uniform sampling} from a state space $S$ of cardinality $N$: run a symmetric ergodic Markov chain $P$ on $S$ for long enough to obtain a random state from within $ε$ total variation distance of the uniform distribution over $S$. The running time of this algorithm, the so-called {\em mixing time} of $P$, is $O(δ^{-1} (\log N + \log ε^{-1}))$, where $δ$ is the spectral gap of $P$. We present a natural quantum version of this algorithm based on repeated measurements of the {\em quantum walk} $U_t = e^{-iPt}$. We show that it samples almost uniformly from $S$ with logarithmic dependence on $ε^{-1}$ just as the classical walk $P$ does; previously, no such quantum walk algorithm was known. We then outline a framework for analyzing its running time and formulate two plausible conjectures which together would imply that it runs in time $O(δ^{-1/2} \log N \log ε^{-1})$ when $P$ is the standard transition matrix of a constant-degree graph. We prove each conjecture for a subclass of Cayley graphs.

Trust and environmental valuation: The impact of culture as system
Creators: name: Lee, Kelvin
Publisher: name: The Australian National University
Year: 2019

description: Economists use various contingent valuation schemes to assess how the environment should be factored in development issues. A standard critique of economics is that it takes preferences as given and does not question where attitudes come from. The thesis examines how contextual factors, institutions, rules, and culture affect people's valuation of environmental goods and services. Drawing on previous literature this thesis examines a set of contextual factors that help determine different attitudes toward environmental evaluation across different countries using specific questions from the World Values Survey. Two of the central figures in this area are Elinor Ostrom and Toshio Yamagishi. Through public goods experiments Ostrom demonstrates the importance of trust for reciprocity for collective action but equally important are the rules that govern the regulation of interpersonal exchanges. There is a large body of work from cross-cultural psychologists who emphasize that there is an individualism-collectivism dimension of culture and that helps explains how much trust there exists in different countries. Building on Ostrom's work, Yamagishi critiques this work. He builds on Ostrom's account arguing that innate motivations driven by culture are not important; rather, it is the mutual formal and informal monitoring and sanctioning that impacts upon individuals' reputations for trustworthiness. The thesis examines Yamagishi's claims in comparison to those of the cross-cultural psychologists' thesis with regard to individuals' environmental valuation measured in terms of their environmental attitudes. Using specific questions that have been posed in the World Values Survey the effects of two groups of independent variables in particular are examined: institutional variables represented by a state's rule of law as proxy for monitoring and sanctioning other actors; and cultural variables operationalized in terms of an individual's cultural orientation and a state's cultural frame. Multilevel ordered logistic regression is utilized to analyze cross-country data by comparing results from the wave 5 dataset against those from the longitudinal dataset of the World Values Survey. The thesis demonstrates that a state's rule of law has a positive impact on one's environmental attitudes when interacted with interpersonal trust and trust in institutions. However, culture's impact on individuals' environmental attitudes seems to contradict expectations of the cross-cultural psychologists; rather, Yamagishi's arguments provide a better explanation. This study further supports Ostrom's and Yamagishi's arguments for the importance of legal institutions and interpersonal trust in influencing one's valuation of the environment.

description: A new coding and queue management algorithm is proposed for communication networks that employ linear network coding. The algorithm has the feature that the encoding process is truly online, as opposed to a block-by-block approach. The setup assumes a packet erasure broadcast channel with stochastic arrivals and full feedback, but the proposed scheme is potentially applicable to more general lossy networks with link-by-link feedback. The algorithm guarantees that the physical queue size at the sender tracks the backlog in degrees of freedom (also called the virtual queue size). The new notion of a node "seeing" a packet is introduced. In terms of this idea, our algorithm may be viewed as a natural extension of ARQ schemes to coded networks. Our approach, known as the drop-when-seen algorithm, is compared with a baseline queuing approach called drop-when-decoded. It is shown that the expected queue size for our approach is $O(\frac1{1-ρ})$ as opposed to $Ω(\frac1{(1-ρ)^2})$ for the baseline approach, where $ρ$ is the load factor.

description: We analysed archival molecular line data of pre-main sequence (PMS) stars in the Lupus and Taurus star-forming regions obtained with ALMA surveys with an integration time of a few minutes per source. We stacked the data of $^{13}$CO and C$^{18}$O (J = 2-1 & 3-2) and CN (N = 3-2, J = 7/2-5/2) lines to enhance the signal-to-noise ratios, and measured the stellar masses of 45 out of 67 PMS stars from the Keplerian rotation in their circumstellar disks. The measured dynamical stellar masses were compared to the stellar masses estimated from the spectroscopic measurements with seven different stellar evolutionary models. We found that the magnetic model of Feiden (2016) provides the best estimate of the stellar masses in the mass range of $0.6~M_{\odot}\leq M_{\star} \leq 1.3~M_{\odot}$ with a deviation of $2σ$) from the dynamical masses, and other, non-magnetic stellar evolutionary models of Siess et al. (2000), Baraffe et al. (2015) and Feiden (2016) show better agreements with the dynamical masses with the deviations of 1.4$σ$ to 1.6$σ$. Our results show the mass dependence of the accuracy of these stellar evolutionary models.

Combined transmission and diffraction around a floating breakwater
Creators: name: Garceau, Nathalie
Publisher: name: University of British Columbia
Year: 2009

description: Wave conditions on the sheltered side of a floating breakwater are commonly approximated by supperposing the results of the transmitted wave field across the breakwater, and the diffracted wave field around the ends of the breakwater, both obtained separately. This thesis describes an experimental and numerical investigation of the suitability of this approach. To evaluate the wave field downwave of the breakwater, three set of laboratory tests were conducted. One relates diffraction around a fixed breakwater extending to the seabed; another to the two-dimensional case of wave transmission across a breakwater located at the water surface; and the third to the three-dimensional case of combined wave transmission and diffraction past a breakwater at the water surfaces. The experiments were carried out for a rectangular caisson with three wave conditions and for both a fixed and freely floating breakwater. Three numerical models of a rectangular breakwater based on linear potential theory were used to predict results relating to transmission coefficient in the case of wave transmission only, wave diffraction only and combined wave transmission and diffraction. The results from the laboratory experiments and the numerical models were compared to validate the numerical models. Also, the addition of the transmission and diffraction solutions were compared with the combined solution, on the basis of experimental results as well as numerical results. The numerical and experimental results have indicated that the superposition approximation generally overestimates the combined situation, particularly for longer waves.

description: Andreev reflection, which corresponds to the tunneling of two electrons from a metallic lead to a superconductor lead as a Cooper pair (or vice versa), can be exploited to measure high frequency noise. A detector is proposed, which consists of a normal lead--superconductor circuit, which is capacitively coupled to a mesoscopic circuit where noise is to be measured. We discuss two detector circuits: a single normal metal -- superconductor tunnel junction and a normal metal separated from a superconductor by a quantum dot operating in the Coulomb blockade regime. A substantial DC current flows in the detector circuit when an appropriate photon is provided or absorbed by the mesoscopic circuit, which plays the role of an environment for the junction to which it couples. Results for the current can be cast in all cases in the form of a frequency integral of the excess noise of the environment weighted by a kernel which is specific to the transport process (quasiparticle tunneling, Andreev reflection,...) which is considered. We apply these ideas to the measurement of the excess noise of a quantum point contact and we provide numerical estimates of the detector current.

description: Multivector fields and differential forms at the continuum level have respectively two commutative associative products, a third composition product between them and various operators like $\partial$, $d$ and $*$ which are used to describe many nonlinear problems. The point of this paper is to construct consistent direct and inverse systems of finite dimensional approximations to these structures and to calculate combinatorially how these finite dimensional models differ from their continuum idealizations. In a Euclidean background there is an explicit answer which is natural statistically.

Morphs in search of meaning: Southeast Solomonic transitive morphology in diachronic perspective
Creators: name: Naitoro, Katerina
Publisher: name: The Australian National University
Year: 2019

description: In this thesis I examine the distribution, functions and the development of transitive morphology in Southeast Solomonic languages, a subgroup of the Oceanic language family. The valency changing devices, and their allomorphs, are analysed both synchronically and diachronically. The synchronic transitivity marking and argument structure systems are compared with the reconstructed system of the ancestral language Proto Oceanic, and the thesis discusses processes which underpin the changes that have taken place, and their motivations. This study of development of transitive morphology in a group of closely related languages allows for both fine grained analysis of cognate and meaning sets as well as for identification of broader patterns. Despite the Southeast Solomonic languages being considered rather conservative in their treatment of the transitive morphology inherited from Proto Oceanic, the data show considerable divergence from the ancestral system and radically different patterns existing among the sister languages. The synchronic differences are largely due to the loss of some valency increasing affixes in some languages and to the different frequencies of use of morphological and analytical devices among the related languages. I propose that the main mechanisms underpinning the changes were analogical extension of existing patterns and reanalysis of surface forms. Extension of use of existing patterns with new verbs is found both in increased use of some devices, in some functions, and in the decreased use of others. Reanalysis has occurred with different devices and has led to a shift in morpheme boundaries as well as to a rise of new forms. Both semantic and phonological similarity is argued to have played an important role in these changes. The composite changes that have taken place in the history of the Southeast Solomonic languages include not only grammaticalisation but notably also counterdirectional change: debonding of previously bound forms, and degrammation. Debonding appears to have taken place more than once and occurred with more than one affix. This makes the Southeast Solomonic languages stand out since this type of change is thought not to be very common cross linguistically. I conclude that the transitivity systems of the Southeast Solomonic languages diverged from the ancestral system, and from each other, through the same processes of change taking place repeatedly over time, with different verbs. Because these processes did not take place in isolation, their outcomes differed depending on the context and the presence and function of other devices in a given language. This highlights the need to consider change holistically as occurring within a linguistic system. Furthermore, multiple motivations for change need to be considered.

description: We propose the phase dynamics induced by spin waves in a superconductor/ferromagnet/superconductor (SC/FM/SC) Josephson junction. The resistively shunted junction (RSJ) model, which describes the dynamics of superconducting phase difference, is extended to include the spin wave excitation by ferromagnetic resonance (FMR) using the gauge invariant phase difference between two s-wave superconductors. The current-voltage characteristics show step structures when the magnetization in FM is driven by tuning the microwave frequency to FMR in the SC/FM/SC junction. The result presents a new route to observe the spin wave excitation using the Josephson effect.

Effects of confining pressure and static shear on liquefaction resistance of Fraser river sand
Creators: name: Stedman, James David.
Publisher: name: University of British Columbia
Year: 2009

description: A comprehensive investigation into the effects of confining stress and static shear levels on the resistance to liquefaction of Fraser river sand is presented. A wide range of initial states characterized by static shear, confining stress and relative density levels are considered. It is shown that both Kσ and Kα factors that are used to modify the cyclic resistance value at a reference confining stress of 100 kPa and no static shear to account for higher confining stresses and static shear depend on all initial state parameters; density, confining stress and static shear levels. The currently used modifying factors Kσ Kα proposed by Seed and Harder (1990) grossly underestimate the cyclic resistance of Fraser river sand regardless of the magnitude of confining stress, static shear and relative density. The under prediction is the largest for loose density states for which the greatest potential for liquefaction exists.

description: We present a detailed study of the spectral and temporal properties of the X-ray and optical emission of GRB050713a up to 0.5 day after the main GRB event. The X-ray light curve exhibits large amplitude variations with several rebrightenings superposed on the underlying three-segment broken powerlaw that is often seen in Swift GRBs. Our time-resolved spectral analysis supports the interpretation of a long-lived central engine, with rebrightenings consistent with energy injection in refreshed shocks as slower shells generated in the central engine prompt phase catch up with the afterglow shock at later times. Our sparsely-sampled light curve of the optical afterglow can be fitted with a single power law without large flares. The optical decay index appears flatter than the X-ray one, especially at later times.

As'adiyah traditions : the construction and reproduction of religious authority in contemporary South Sulawesi
Creators: name: Halim, Wahyuddin
Publisher: name: The Australian National University
Year: 2018

description: As'adiyah is the largest and most significant religious institution in South Sulawesi from the second part of the twentieth century, and Anregurutta Muhammad As'ad al-Bugis (1907-1952), the founder of this institution, has been a significant figure in the formation, transformation and reproduction of Islamic authority in the region. The literature on Islamic education and Islamic authority in Indonesia has tended to focus on Java and to a lesser extent on Sumatra. In addition, most of these studies still pay little attention on the complex relation between religious educational institutions and the formation and reproduction of religious authority, a topic of great significance to understand. This study contributes to our understanding of the significant role of religious education and institutions in Indonesia and their crucial influence on the construction and reproduction of religious authority, through a study of a major non-Java based religious network. This anthropological study explores the multiple dimensions of influence of As'adiyah as a religious and educational institution in especially local community. It contributes to our understanding of the development of Islam in South Sulawesi and beyond, particularly in the Bugis diaspora. In the unique context of the hierarchical Bugis society, As'adiyah has provided an avenue for an upwards social mobility for all people, regardless of their social status. Through its educational and religious programs, in particular, this institution has enabled many young Muslims to obtain religious knowledge and to accumulate social and cultural capital which are essential for their claim for religious authority and for their becoming elite members of society. As'adiyah was first merely madrasah (Islamic school) and pesantren (Islamic boarding school) which later developed into a socio-religious institution whose programs encompassed religious, social, cultural and economic aspects of the local Muslim community. In the field of Islamic education, As'adiyah operates various formal and non-formal Islamic education programs, the branches of which can be found in many parts of South Sulawesi province and elsewhere. This study looks at how religious authority disseminated, exercised and maintained by As'adiyah within the Muslim society in Wajo and examines the role of this institution as the transmitter, interpreter and mediator of global, textual Islam to the local context of Muslim society. Finally, this study investigates the process though which As'adiyah has come to provide a sub-religious Islamic identity as well as sustaining cultural (Bugis) identity among its students, graduates, members and affiliates.

description: We discuss instrumental and analytic methods that have been developed for the first generation of bolometric cosmic microwave background (CMB) polarimeters. The design, characterization, and analysis of data obtained using Polarization Sensitive Bolometers (PSBs) are described in detail. This is followed by a brief study of the effect of various polarization modulation techniques on the recovery of sky polarization from scanning polarimeter data. Having been successfully implemented on the sub-orbital Boomerang experiment, PSBs are currently operational in two terrestrial CMB polarization experiments (QUaD and the Robinson Telescope). We investigate two approaches to the analysis of data from these experiments, using realistic simulations of time ordered data to illustrate the impact of instrumental effects on the fidelity of the recovered polarization signal. We find that the analysis of difference time streams takes full advantage of the high degree of common mode rejection afforded by the PSB design. In addition to the observational efforts currently underway, this discussion is directly applicable to the PSBs that constitute the polarized capability of the Planck HFI instrument.

Imprint of nuclear bubble in nucleon-nucleus diffraction

description: Background: The density of most nuclei is constant in the central region and is smoothly decreasing at the surface. A depletion in the central part of the nuclear density can have nuclear structure effects leading to the formation of "bubble" nuclei. However, probing the density profile of the nuclear interior is, in general, very challenging. Purpose: The aim of this paper is to investigate the nuclear bubble structure, with nucleon-nucleus scattering, and quantify the effect that has on the nuclear surface profile. Method: We employed high-energy nucleon-nucleus scattering under the aegis of the Glauber model to analyze various reaction observables, which helps in quantifying the nuclear bubble. The effectiveness of this method is tested on $^{28}$Si with harmonic-oscillator (HO) densities, before applying it on even-even $N = 14$ isotones, in the $22 \leq A \leq 34$ mass range, with realistic densities obtained from antisymmetrized molecular dynamics (AMD). Results: Elastic scattering differential cross sections and reaction probability for the proton-$^{28}$Si reaction are calculated using the HO density to design tests for signatures of nuclear bubble structure. We then quantify the degree of bubble structure for $N = 14$ isotones with the AMD densities by analyzing their elastic scattering at 325, 550 and 800 MeV incident energies. The present analyses suggest $^{22}$O as a candidate for a bubble nucleus, among even-even $N = 14$ isotones, in the $22 \leq A \leq 34$ mass range. Conclusion: We have shown that the bubble structure information is imprinted on the nucleon-nucleus elastic scattering differential cross section, especially in the first diffraction peak. Bubble nuclei tend to have a sharper nuclear surface and deformation seems to be a hindrance in their emergence.

description: Aims: We have carried out an infrared study of the southern Galactic massive star forming region associated with IRAS 14416-5937. Methods: This star forming region has been mapped simultaneously in two far infrared bands at ~ 150 & 210 micron using the TIFR 1-m balloon borne telescope with ~ 1' angular resolution. We have used 2MASS JHK$_s$ as well as Spitzer-GLIMPSE data of this region to study the stellar populations of the embedded young cluster. This region comprises of two sources, designated as A & B and separated by ~ 2 pc. The spectrum of a region located close to the source A obtained using the Long Wavelength Spectrometer (LWS) on-board the Infrared Space Observatory (ISO), is presented. Emission from warm dust and from Unidentified Infrared Bands (UIBs) is estimated using the mid-infrared data of the MSX survey. Results: The spatial distributions of (1) the temperature of cool dust and (2) optical depth at 200 micron have been obtained taking advantage of the similar beams in both the TIFR bands. A number of atomic fine structure lines have been detected in the ISO-LWS spectrum, which have been used to estimate the electron density and the effective temperature of the ionising radiation in this region. From the near and mid infrared images, we identify a dust lane due north-west of source A. The dust lane is populated by Class I type sources. Class II type sources are found further along the dust lane as well as below it. Self consistent radiative transfer models of the two sources (A and B) are in good agreement with the observed spectral energy distributions. Conclusions: The spatial distribution of young stellar objects in and around the dust lane suggests that active star formation is taking place along the dust lane and is possibly triggered by the expanding HII regions of A and B.

description: We consider classes $ \mathcal{A}_M(S) $ of functions holomorphic in an open plane sector $ S $ and belonging to a strongly non-quasianalytic class on the closure of $ S $. In $ \mathcal{A}_M(S) $, we construct functions which are flat at the vertex of $ S $ with a sharp rate of vanishing. This allows us to obtain a Borel-Ritt type theorem for $ \mathcal{A}_M(S) $ extending previous results by Schmets and Valdivia. We also derive a division property for ideals of flat ultradifferentiable functions, in the spirit of a classical $ C^\infty $ result of Tougeron.
