description: Let F_*(X, Y) be the space of base-point-preserving maps from a connected finite CW complex X to a connected space Y. Consider a CW complex of the form X cup_{alpha}e^{k+1} and a space Y whose connectivity exceeds the dimension of the adjunction space. Using a Quillen-Sullivan mixed type model for a based mapping space, we prove that, if the bracket length of the attaching map alpha: S^k --> X is greater than the Whitehead length WL(Y) of Y, then F_*(X cup_{alpha}e^{k+1}, Y) has the rational homotopy type of the product space F_*(X, Y) times Omega^{k+1}Y. This result yields that if the bracket lengths of all the attaching maps constructing a finite CW complex X are greater than WL(Y) and the connectivity of Y is greater than or equal to dim X, then the mapping space F_*(X, Y) can be decomposed rationally as the product of iterated loop spaces.

description: In the usual cosmological inflationary scenarios, the scalar field -- inflaton -- is usually assumed to be an elementary field. In this essay, we ask: What are the observational signatures, if the scalar field is a spinor condensate? and Is there a way to distinguish between the canonical scalar field and the spinor condensate driven models? In the homogeneous and isotropic background, we show that, although the dark-spinor (Elko) condensate leads to the identical acceleration equation as that of the canonical scalar field driven inflation, the dynamics of the two models are different. In the slow-roll limit, we show that the model, predicts a running of scalar spectral index consistent with the WMAP data. We show that the consistency relations between the spinor condensate and canonical scalar field driven model are different which can be tested using the future CMB and gravitational wave missions.

Momentum Dependent Dark Matter Scattering

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: It is usually assumed that WIMPs interact through spin-independent and spin-dependent interactions. Interactions which carry additional powers of the momentum transfer, q^2, are assumed to be too small to be relevant. In theories with new particles at the ~ GeV scale, however, these q^2-dependent interactions can be large, and, in some cases dominate over the standard interactions. This leads to new phenomenology in direct detection experiments. Recoil spectra peak at non-zero energies, and the relative strengths of different experiments can be significantly altered. We present a simple parameterization for models of this type which captures much of the interesting phenomenology and allows a comparison between experiments. As an application, we find that dark matter with momentum dependent interactions coupling to the spin of the proton can reconcile the DAMA annual modulation result with other experiments.

description: In this note, we calculate the branching ratio of B_c\to J/ψK in the framework of perturbative QCD approach based on k_T factorization. This decay can occur only via tree level diagrams in the Standard Model. We find that the branching ratio of B_c\to J/ψK is about (1-3)\times10^{-4}. The large branching ratio and the clear signals of the final states make the measurement of B_c\to J/ψK easily at LHC-b experiments.

The Effect of partial reinforcement before and after continuous reinforcement on acquisition level and resistance to extinction.
Creators: name: Husband, James Dalla Thorne
Publisher: name: University of British Columbia
Year: 2011

description: Sutherland, Mackintosh, and Wolfe (1965) demonstrated that continuous reinforcement given subsequent to partial reinforcement resulted in superior resistance to extinction than did continuous reinforcement administered prior to partial reinforcement. Because the experimenters did not make compensations for different acquisition asymptotes in their analysis of the extinction data, the interpretation of their results is questionable. Thelos and McGinnis (1967) obtained results contrary to those obtained by the latter experimenters. This study was run in order to obtain additional information pertaining to the effects of shifts of reinforcement schedules on resistance to extinction. Extended acquisition trials were used with the expectation of bringing the six experimental groups up to the same terminal asymptotic levels. When Ss were approximately 45 days old, Ss were randomly assigned to one of six acquisition conditions. These conditions were: 96 partial reinforcement trials, 192 partial reinforcement trials, 96 partial reinforcement trials followed by 96 continuous reinforcement trials, 96 continuous reinforcement trials followed by 96 partial reinforcement trials, 192 continuous reinforcement trials, and 96 continuous reinforcement trials. Following training in a straight runway, all Ss received 60 nonreward trials given in blocks of 6 trials a day. Time measures were taken of runway performance on acquisition and extinction trials. The results supported the hypothesis that extended training would produce equivalent terminal asymptotic running speeds in acquisition. None of the hypotheses made by Sutherland, Mackintosh, and Wolfe (1965) or by Thelos and McGinnis (1967) were supported by the results of the experiment; no significant partial reinforcement effect was obtained.

description: EVOC (for EVOlution of Culture) is a computer model of culture that enables us to investigate how various factors such as barriers to cultural diffusion, the presence and choice of leaders, or changes in the ratio of innovation to imitation affect the diversity and effectiveness of ideas. It consists of neural network based agents that invent ideas for actions, and imitate neighbors' actions. The model is based on a theory of culture according to which what evolves through culture is not memes or artifacts, but the internal models of the world that give rise to them, and they evolve not through a Darwinian process of competitive exclusion but a Lamarckian process involving exchange of innovation protocols. EVOC shows an increase in mean fitness of actions over time, and an increase and then decrease in the diversity of actions. Diversity of actions is positively correlated with population size and density, and with barriers between populations. Slowly eroding borders increase fitness without sacrificing diversity by fostering specialization followed by sharing of fit actions. Introducing a leader that broadcasts its actions throughout the population increases the fitness of actions but reduces diversity of actions. Increasing the number of leaders reduces this effect. Efforts are underway to simulate the conditions under which an agent immigrating from one culture to another contributes new ideas while still fitting in.

description: The structure of cones of positive and k-positive maps acting on a finite-dimensional Hilbert space is investigated. Special emphasis is given to their duality relations to the sets of superpositive and k-superpositive maps. We characterize k-positive and k-superpositive maps with regard to their properties under taking compositions. A number of results obtained for maps are also rephrased for the corresponding cones of block positive, k-block positive, separable and k-separable operators, due to the Jamiolkowski-Choi isomorphism. Generalizations to a situation where no such simple isomorphism is available are also made, employing the idea of mapping cones. As a side result to our discussion, we show that extreme entanglement witnesses, which are optimal, should be of special interest in entanglement studies.

Symplectic Three-Algebra Unifying N=5,6 Superconformal Chern-Simons-Matter Theories

description: We define a 3-algebra with structure constants being symmetric in the first two indices. We also introduce an invariant anti-symmetric tensor into this 3-algebra and call it a symplectic 3-algebra. The general N=5 superconformal Chern-Simons-matter (CSM) theory with SO(5) R-symmetry in three dimensions is constructed by using this algebraic structure. We demonstrate that the supersymmetry can be enhanced to N=6 if the sympelctic 3-algebra and the fields are decomposed in a proper fashion. By specifying the 3-brackets, some presently known N=5, 6 superconformal theories are described in terms of this unified 3-algebraic framework. These include the N=5, Sp(2N) X O(M) CSM theory with SO(5) R-symmetry , the N=6, Sp(2N) X U(1) CSM theory with SU(4) R-symmetry, as well as the ABJM theory as a special case of U(M) X U(N) theory with SU(4) R-symmetry.

A Critical study of Byron's Cain
Creators: name: Jones, Lindsay Maxwell
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is a critical study of Lord Byron's poetic drama, Cain. Most critics in the past have seen the work as a personal statement of religious skepticism on the part of Lord Byron, and hence as an out-and-out attack on traditional, Christian doctrine. With this preconception in mind, they have concerned themselves with pointing out attitudes and ideas in the play which may be said to be antithetical to the Christian world view, and they have then assessed the play simply in these terms. It is the contention of this paper that this presupposition has led the critics away from the realm of meaning intended by Lord Byron, and that a proper understanding of the play can only arise from a full, critical study of the central issue with which this "metaphysical" drama is concerned. The method followed is to analyse the differences in form, structure and argument between two accounts of this story - that found in the Bible, and Byron's poetic drama - on the assumption that such radical changes as we shall note are essential to the conveyance of Byron's peculiar meaning, and that a study of them must reveal the proper coherence and unity of Byron's work. We shall see that Cain is not a mere recounting of this story, but rather that it is a reconceptualization of the predicament facing Adam and Eve and the first family, structured so as to focus upon the human situation, so chat in the work Byron is not concerned with religious values, but with human values; not concerned to advance or refute traditional, religious concepts, but to reveal his insights into the common, human predicament.

description: We study the marine terraces of the southern side of the Sibari Plain in Northern Calabria (Italy) through the use of traditional and quantitative analyses of the Digital Terrain Model (DTM). The main aim of the present work consists in the extensive use of GIS tools that were never used before in the area, and in checking the applicability of this procedure. The terraced surfaces identified using photo interpretation and those recognized semi-automatically through the GIS tools were compared to finally produce a consensus map. In the final map, we identified 272 terraced surfaces and 62 morphological features associated with inner margins (i.e. paleoshorelines). The main map shows a well-developed flight of seven orders of marine terraces with elevation ranging from 45 to 360 m asl and age ranging from Marine Isotope Stage (MIS) 5a to 11.

description: We study the massless field on $D_n = D \cap \tfrac{1}{n} \Z^2$, where $D \subseteq \R^2$ is a bounded domain with smooth boundary, with Hamiltonian $\CH(h) = \sum_{x \sim y} \CV(h(x) - h(y))$. The interaction $\CV$ is assumed to be symmetric and uniformly convex. This is a general model for a $(2+1)$-dimensional effective interface where $h$ represents the height. We take our boundary conditions to be a continuous perturbation of a macroscopic tilt: $h(x) = n x \cdot u + f(x)$ for $x \in \partial D_n$, $u \in \R^2$, and $f \colon \R^2 \to \R$ continuous. We prove that the fluctuations of linear functionals of $h(x)$ about the tilt converge in the limit to a Gaussian free field on $D$, the standard Gaussian with respect to the weighted Dirichlet inner product $(f,g)_\nabla^β= \int_D \sum_i β_i \partial_i f_i \partial_i g_i$ for some explicit $β= β(u)$. In a subsequent article, we will employ the tools developed here to resolve a conjecture of Sheffield that the zero contour lines of $h$ are asymptotically described by $SLE(4)$, a conformally invariant random curve.

description: Jibei Island, in Taiwan's Penghu area, is famous for its abundance of stone fish weirs (SFWs). This research used historical charts, archives, and high-resolution orthophoto images for the SFWs mapping and spatial pattern analysis exercise. We found that the birthplace of SFWs was in the southern part of Jibei Port and Mudou Isle. In the early stage of the Japanese governing period (1895–1945), SFWs were mainly constructed in the North and North-West parts of the Jibel Isle and gradually migrated toward the east and north. In the middle to late Japanese governing period, the SFWs’ construction hot zone was in the South-West and South-East sides of the Jibei Isle. Understanding the SFW's evolution in the Jibel area is critical for local and regional cultural history, offering insights into land use and fish culture in Penghu and shedding light on ancient fishing culture in the broader pan-Pacific region.

Creating and Analysing Rauzy Graphs for DNA Sequences
Creators: name: Nahodil, D
Publisher: name: University Of Tasmania
Year: 2023

description: Bioinformatics is a new and interesting field of research, and genuine discoveries are being made all the time. This project aims to investigate the application of a mathematical tool, called a Rauzy graph, to the problem of classifying DNA sequences. This project aims to learn more about the properties of DNA, and the nature of the graphs themselves. The work for the project involves developing an algorithm for the computer to generate Rauzy graphs. Different sets of DNA sequences are used to build graphs from, and their properties analysed to investigate their behaviour in the biology domain. The results of the work show that differences in DNA sequences do affect the structure of their Rauzy graphs and that, through this, the properties of the Rauzy graphs of DNA sequences could be used to classify those sequences.

description: Various terms in orthopedics are formed using or incorporating the name of native bones and these terms then describe a clinical entity or a procedure. The term thus created, however, may or may not be directly related to the bone associated. There are a few interesting examples of such terms that are encountered in the orthopedic literature. A short recollection of those few notable terms that have the name of a known bone within their terminology is described here for general reading and knowledge.

Two of the most challenging ones, which have been debated for decades, concern the effect of disorder on superconductivity and quantum magnetism. Recent progress in ultracold atomic gases paves the way towards realization of versatile quantum simulators which will be useful to solve these questions. In addition, ultracold gases offer original situations and viewpoints, which open new perspectives to the field of disordered systems.

description: A geological, geomorphological and geo-touristic map, at 1:5000 scale, has been produced for the most representative area of the regional ‘Special Nature Reserve of Montalbano Jonico Badlands’, with the aim to represent the scientific and landscape features which allowed the establishment of the Reserve. The area is located in the Province of Matera (Basilicata), on the southwestern sector of the Apennines Quaternary foredeep, in Southern Italy. The map highlights stratigraphic signatures of international interest and badland landscapes, imprinted on a clayey marine succession straddling the Early-Middle Pleistocene boundary. This stratigraphic interval can be considered as an international reference section for global paleoclimatic signatures during Marine Oxygen Isotopic Stages 20–18 and for the base of the Middle Pleistocene Subseries/Subepoch. With the goal to disseminate these knowledges, to improve future research and to promote sustainable geo-tourism, the map allows visitors to enjoy the scientific features and scenery of the Reserve.

Most of our results are obtained without the assumption of the existence of unique equilibrium measures or the differentiability of pressure functions. Some examples are constructed to illustrate the irregularity and the complexity of multifractal behaviors in the sub-additive case and in the case that the entropy map that is not upper-semi continuous.

Applying Expert System Technology in a Distributed Monitoring System: An Efficient Response Mechanism for Unknown Threats
Creators: name: Cooke, HBM
Publisher: name: University Of Tasmania
Year: 2023

description: Detecting unknown threats is a paradox; how do you detect a threat if it is not known to exist? The answer is that unknown threat detection is the process of making a previously unknown threat identifiable in the shortest possible time frame. This thesis examines the possibility of creating an unknown threat detection mechanism that security experts can use for developing a flexible protection system for networks. A system that allows the detection of unknown threats through distributed host based monitoring and the incorporation of dynamic and flexible logics with situational knowledge is described as well as the mechanisms used to develop such a system is illustrated. The system not only allows the detection of new threats but does so in a fast and efficient manner to increase the available time for responding to these threats.

description: We have grown lead iron niobate thin films with composition Pb(Fe1/2Nb1/2)O3 (PFN) on (0 0 1) SrTiO3 substrates by pulsed laser deposition. The influence of the deposition conditions on the phase purity was studied. Due to similar thermodynamic stability spaces, a pyrochlore phase often coexists with the PFN perovskite phase. By optimizing the kinetic parameters, we succeeded in identifying a deposition window which resulted in epitaxial perovskite-phase PFN thin films with no identifiable trace of impurity phases appearing in the X-ray diffractograms. PFN films having thicknesses between 20 and 200 nm were smooth and epitaxially oriented with the substrate and as demonstrated by RHEED streaks which were aligned with the substrate axes. X-ray diffraction showed that the films were completely c-axis oriented and of excellent crystalline quality with low mosaicity (X-ray rocking curve FWHM<0.09). The surface roughness of thin films was also investigated by atomic force microscopy. The root-mean-square roughness varies between 0.9 nm for 50-nm-thick films to 16 nm for 100-nm-thick films. We also observe a correlation between grain size, surface roughness and film thickness.

description: The geographical configuration of northwest Ethiopia has changed often and significantly during the previous four centuries, according to a meta-analysis of historical maps. Boundary lines of languages in use and of territorial control were reported on the Main Map. Sixty-six coeval historical maps depict the territorial control of Western Tigray, also known as Welkait and its surrounding districts. The area is specifically recorded as part of Tigray from 1707 to 1794, 1831 to 1886, and 1939 to 1941. From 1891 to 1909 and 1944 to 1990, it is labelled as being a part of Amhara or Gondar. Welkait is shown in other eras as either being autonomous or a component of a broader Mezaga lowland territory. The agreement of 32 ethnolinguistic maps of northern Ethiopia from the twentieth century sustains the post-1991 extent of the Tigray region in the districts located between the Tekeze River and the Sudanese border. In Ethiopia, the current regional organisation is determined by ethnolinguistic demographics rather than the historical dominance of a group over that land.In Western Tigray (north Ethiopia), there have been challenges with identity and territorial conquest.Based on ancient maps, we drew the successive positions of the border between the western portions of Tigray and Amhara.Territorial organisation varied strongly throughout the centuries, with most maps showing borders positioned south of the current boundary of the two regions.According to the near consensus of 20th C. language maps, the present size of the Tigray Region matches the extent of the Tigrinya language in Ethiopia.This map supports an approach where the resolution of territorial disputes reflects the ethnolinguistic makeup.

Transfer Of Learnt Knowledge With Card Games
Creators: name: Livingston, JR
Publisher: name: University Of Tasmania
Year: 2023

description: Reinforcement learning algorithms are an important machine learning technique, which can be applied to the process of learning many tasks. Much of the existing work on improving these algorithms, and analysis into the usefulness, only considers agents which have to perform one task. Many real-world applications of reinforcement learning algorithms require that an agent can cope with small variations in their given task, and the application of their learnt knowledge to those tasks. I consider the application of reinforcement learning algorithms to several card games, and the process of transferring learnt knowledge between these card games. The two card games used, Cut-Throat Euchre and Sergent-Major, are similar in their rules and the strategies that are used to play the game. The differences between the two games are used to measure the effectiveness of transferring knowledge between them, using a common-state approach. These simulations of playing card-games indicate that the tasks of playing these two games are similar enough that knowledge can effectively be shared between the two. An improvement in the ability of an agent to play one of the games, results in a significant improvement in the ability of the agent to play the other game.

description: Experiments that look for nonlinear quantum dynamics test the fundamental premise of physics that one of two separate systems can influence the physical behavior of the other only if there is a force between them, an interaction that involves momentum and energy. The premise is tested because it is the assumption of a proof that quantum dynamics must be linear. Here variations of a familiar example are used to show how results of nonlinear dynamics in one system can depend on correlations with the other. Effects of one system on the other, influence without interaction between separate systems, not previously considered possible, would be expected with nonlinear quantum dynamics. Whether it is possible or not is subject to experimental tests together with the linearity of quantum dynamics. Concluding comments and questions consider directions our thinking might take in response to this surprising unprecedented situation.

description: A goal of the emerging field of quantum control is to develop methods for quantum technologies to function robustly in the presence of noise. Central issues are the fundamental limitations on the available information about quantum systems and the disturbance they suffer in the process of measurement. In the context of a simple quantum control scenario--the stabilization of non-orthogonal states of a qubit against dephasing--we experimentally explore the use of weak measurements in feedback control. We find that, despite the intrinsic difficultly of implementing them, weak measurements allow us to control the qubit better in practice than is even theoretically possible without them. Our work shows that these more general quantum measurements can play an important role for feedback control of quantum systems.

Duality covariant variables for STU-model in presence of non-holomorphic corrections

description: It is known that non-holomorphic corrections are necessary in order to get duality invariant free energy and entropy function. However the present methods of incorporating non-holomorphic corrections are in conflict with special geometry properties of moduli space. The moduli fields do not transform in duality covariant way and their duality transformation also involves the graviphoton field strength. In the present note we construct duality covariant moduli fields for STU-model perturbatively in powers of the graviphoton field strength and demonstrated their existence upto second order.

Novels and the poetry of Philip Larkin.
Creators: name: Mayne, Joan Sheila
Publisher: name: University of British Columbia
Year: 2011

description: Philip Larkin has been considered primarily in terms of his contribution to the Movement of the Fifties; this thesis considers Larkin as an artist in his own right. His novels, Jill and A Girl in Winter, and his first volume of poetry, The North Ship, have received very little critical attention. Larkin's last two volumes of poetry, The Less Deceived and The Whitsun Weddings, have been considered as two very similar works with little or no relation to his earlier work. This thesis is an attempt to demonstrate that there is a very clear line of development running through Larkin's work, in which the novels play as important a part as the poetry. The North Ship contains in embryonic form those themes which become important in the later work; it is different in technique, largely because it is immature and influenced very strongly by the poetry which Larkin was reading at the time of writing. The lyric element in this volume of poetry anticipates the later development in Larkin's poetic technique. The novels are considered as novel-poems and their poetic quality is demonstrated through close analysis which reveals their closely patterned quality and that the narrative level is important only as it mirrors the internal action of the central characters. The novels develop ideas which are present in The North Ship and they represent a considerable advance in the writer's confidence in handling his material in his own way. The Less Deceived and The Whitsun Weddings use many of the techniques of the novels and are very closely linked with them in their basic themes. The Less Deceived shows Larkin becoming increasingly self-aware and from this awareness examining his society in a new light. In The Whitsun Weddings his self-awareness is increased and he is more tolerant of his own failings. His tolerance is extended also to his society and the volume as a whole represents Larkin's attempt to view man and society clearly and to accept them as they are. Both the novels and the later poetry contain lyric elements of an unusual nature. The development throughout his work is based on his ability to develop his technique to express his changing ideas. He moves from the use of totally conventional forms to express conventional ideas to the use of individualistic forms, developed from traditional material including the lyric, to express his sense of a society looking for, but not finding, order in traditional values.
Entanglement, invariants, and phylogenetics
Creators: name: Sumner, JG
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis develops and expands upon known techniques of mathematical physics relevant to the analysis of the popular Markov model of phylogenetic trees required in biology to reconstruct the evolutionary relationships of taxonomic units from biomolecular sequence data. The techniques of mathematical physics are plethora and have been developed for some time. The Markov model of phylogenetics and its analysis is a rela- tively new technique where most progress to date has been achieved by using discrete mathematics. This thesis takes a group theoretical approach to the problem by beginning with a remarkable mathematical parallel to the process of scattering in particle physics. This is shown to equate to branching events in the evolutionary history of molecular units. The major technical result of this thesis is the derivation of existence proofs and computational techniques for calculating polynomial group invariant functions on a multi-linear space where the group action is that relevant to a Markovian time evolution. The practical results of this thesis are an extended analysis of the use of invariant functions in distance based methods and the presentation of a new recon- struction technique for quartet trees which is consistent with the most general Markov model of sequence evolution.

description: We have shown both experimentally and theoretically that polarization-independent broad-band absorption of electromagnetic waves by an overdense plasma, caused by surface plasmon-polaritons (SPP) excitation, can be achieved due to combination of two factors: a non-zero angle of incidence and a two-dimensional circular diffraction grating placed at a properly chosen distance in front of the plasma boundary. Direct detection of SPP has been achieved for the first time using a miniature antenna imbedded in the plasma.

Sharp ill-posedness result for the periodic Benjamin-Ono equation
Creators: name: Molinet, Luc
Publisher: name: arXiv
Year: 2008
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics
subject: 35B20, 35Q53

description: We prove the discontinuity for the weak $ L^2(\T) $-topology of the flow-map associated with the periodic Benjamin-Ono equation. This ensures that this equation is ill-posed in $ H^s(\T) $ as soon as $ s<0 $ and thus completes exactly the well-posedness result obtained by the author.
description: This paper has been withdrawn by the author since there were errors in the calculus of the defect coefficient in Page 11. The corrected calculus gives actually zero which do not lead to a contradiction on the continuity of the flow-map of the Benjamin-Ono equation. The author warmly thank Professor Patrick G\'erard for having pointing out this error to him

description: Landslide inventory maps are the first and main information level in studies of reactivation of previous landslides and susceptibility, hazard and risk maps of future landslides. Due to its geographical location and tectonic setting, the Dominican Republic is exposed to several geological risks, among which landslides stand out. In this study, we present a landslide inventory elaborated in three selected zones with particular geographical, lithological, tectonic and climatic characteristics: Puerto Plata, Santiago de los Caballeros and Jarabacoa. A total of 6085 landslides have been recorded (56% in S, 29% in P and 15% in J), which have been classified according to their geometry, propagation mechanism, affected material, thickness and activity. The detected factors that control the distribution and type of gravitational deposits are lithology and geologic structure, as well as rainfall and active faulting along the Camú, Septentrional and Bonao-La Guácara fault zones.
Leading corrections to local approximations

description: For the kinetic energy of 1d model finite systems the leading corrections to local approximations as a functional of the potential are derived using semiclassical methods. The corrections are simple, non-local functionals of the potential. Turning points produce quantum oscillations leading to energy corrections, which are completely different from the gradient corrections that occur in bulk systems with slowly-varying densities. Approximations that include quantum corrections are typically much more accurate than their local analogs. The consequences for density functional theory are discussed.
