description: We develop a consistent relativistic generalization of collective coordinate quantization of field theory solitons. Our principle of introducing collective coordinates is that the equations of motion of the collective coordinates ensure those of the original field theory. We illustrate this principle with the quantization of spinning degrees of freedom of Skyrmion representing baryons. We calculate the leading relativistic corrections to the static properties of nucleons, and find that the corrections are non-negligible ones of 10% to 20%.

description: Studies demonstrate that long non-coding RNAs (lncRNAs) play vital roles in cancer progression. However, the expression pattern and molecular mechanisms of lncRNA FAM83A-AS1 in lung cancer remain largely unclear. Here, we analyzed FAM83A-AS1 expression in lung cancer tissues from three RNA-sequencing (RNA-Seq) datasets and validated these results using quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) in an independent set of lung adenocarcinoma. Cell proliferation, migration, invasion, and autophagy were analyzed after knockdown FAM83A-AS1 with siRNAs. The underlying molecular mechanisms of FAM83A-AS1 were performed by Western blot, qRT-PCR, and RNA-seq analysis. We found that FAM83A-AS1 was up-regulated in lung cancer and elevated expression was associated with poor patient survival. These results were confirmed using RT-PCR in an independent set of lung cancer. Functional study indicated that FAM83A-AS1 knockdown reduced cell proliferation, migration, invasion, and colony formation in cancer cells. FAM83A-AS1 silencing induced autophagy and cell cycle arrest at G2. Mechanistically, serval oncogenic proteins such as EGFR, MET, PI3K, and K-RAS were decreased upon FAM83A-AS1 silencing, while phosphor AMPKα and ULK1 were increased. Based on the above results, we believe that FAM83A-AS1 may have potential as a diagnosis/prognosis marker and its oncogenic role and autophagy regulation may be through MET-AMPKα signaling, which could lead to potential targeting for lung cancer therapy.

Time-Varying Autoregressions in Speech: Detection Theory and Applications

description: This article develops a general detection theory for speech analysis based on time-varying autoregressive models, which themselves generalize the classical linear predictive speech analysis framework. This theory leads to a computationally efficient decision-theoretic procedure that may be applied to detect the presence of vocal tract variation in speech waveform data. A corresponding generalized likelihood ratio test is derived and studied both empirically for short data records, using formant-like synthetic examples, and asymptotically, leading to constant false alarm rate hypothesis tests for changes in vocal tract configuration. Two in-depth case studies then serve to illustrate the practical efficacy of this procedure across different time scales of speech dynamics: first, the detection of formant changes on the scale of tens of milliseconds of data, and second, the identification of glottal opening and closing instants on time scales below ten milliseconds.

Combined free and forced convection through vertical noncircular ducts and passages
Creators: name: Ansari, Saghir A.
Publisher: name: University of British Columbia
Year: 2011

description: The problem of laminar combined free and forced convection through vertical noncircular ducts and passages in the fully developed region has been treated. The fluid properties are considered to be constant, except the variation of the density in the buoyancy term of the momentum equation. Pressure work and viscous dissipation terms of the energy equation have been neglected. Heat flux has been considered to be constant in the flow direction. A general solution to the problem has been obtained in "the form of infinite series containing modified Bessel functions. Two possible thermal boundary conditions on the circumference of the heated wall have been analyzed, Case 1 - uniform circumferential wall temperature, and Case 2 - uniform circumferential wall heat flux. Information of engineering interest like Nusselt number, heat flux, ratio, shear stress ratio, temperature distribution on the' wall, velocity and temperature distributions in the flow field have been obtained for two sets of geometries, namely, (i) flow through regular polygonal ducts, and (ii) flow between cylinders arranged in regular arrays. For flow through regular polygonal ducts, the case of uniform circumferential wall temperature results in higher values of Nusselt numbers as compared to the case of uniform circumferential wall heat flux. This difference in Nusselt number values decreases as the number of sides of the regular polygon is increased, until for a circle it completely disappears. For both the cases, at higher values of Rayleigh number, the Nusselt number is less sensitive to the number of sides of the polygon. Also, at higher values of Rayleigh number, both the cases tend to produce the same results. For low sided polygons, an increase in Rayleigh number tends to shift the maximum value of shear stress from the centre of the duct wall towards the apex of the duct. For flow between cylinders arranged in regular arrays, Case 1 results in higher values of Nusselt number compared to Case 2, for low spacing ratios. However, as the spacing ratio is increased, the two cases tend to produce the same results. Cylinders arranged in equilateral triangular arrays produce higher values of Nusselt number compared to those in square arrays. This difference in Nusselt number values decreases when the spacing ratio is high. For higher values of Rayleigh number, however, the results are less sensitive to the type of arrays. Also, at higher values of Rayleigh number, both the cases tend to produce the same results.

description: A collection of pairwise mutually unbiased bases (in short: MUB) in d>1 dimensions may consist of at most d+1 bases. Such "complete" collections are known to exists in C^d when d is a power of a prime. However, in general little is known about the maximal number N(d) of bases that a collection of MUBs in C^d can have. In this work it is proved that a collection of d MUBs in C^d can be always completed. Hence N(d) cannot be d and when d>1 we have a dichotomy: either N(d)=d+1 (so that there exists a complete collection of MUBs), or N(d)\leq d-1. In the course of the proof an interesting new characterization is given for a linear subspace of M_d(C) to be a subalgebra.
description: v2: An interesting new characterization is added for a linear subspace of M_d(C) to be a subalgebra. This in turn is used to produce a more elegant proof for the main theorem. Also, more similarities are noted between the case of orthogonal Latin squares and that of mutually unbiased bases

description: We address the problem of diversification in religions by studying selection on cultural memes that colonize humans hosts. In analogy to studying the evolution of pathogens or symbionts colonizing animal hosts, we use models for host-pathogen dynamics known from theoretical epidemiology. In these models, religious memes colonize individual humans. Rates of transmission of memes between humans, i.e., transmission of cultural content, and rates of loss of memes (loss of faith) are determined by the phenotype of the cultural memes, and by interactions between hosts carrying different memes. In particular, based on the notion that religion can lead to oppression of lower classes once a religious society has reached a certain size, we assume that the rate of loss increases as the number of humans colonized by a particular meme phenotype increases. This generates frequency-dependent selection on cultural memes, and we use evolutionary theory to show that this frequency dependence can generate the emergence of coexisting clusters of different meme types. The different clusters correspond to different religions, and hence our model describes the emergence of distinct descendent religions from single ancestral religions.

An anti-episcopal drive and the beginning of the English revolution
Creators: name: Bugler Jr. , Henry
Publisher: name: University of British Columbia
Year: 2011

description: The anti-episcopal drive which took place during the first fifteen months of the Long Parliament has long been ignored as a problem worth studying for its own merits. Usually the episcopal crisis of 1640-1642 is considered to be part of a larger crisis since the expulsion of the bishops from the House of Lords was a prelude to the English Revolution. Yet the anti-episcopal drive is of great interest and significance both in itself and in the fact that it was the first time in English history that a popular outcry changed the constitutional foundation of the English Government. It is difficult to isolate this subject from the many other political currents of which it is a part, but this study intends to do so as much as possible. However, the fact remains that in fifteen months, from 3 November, 1640 when the Long Parliament commenced, to 15 February, 1642 when the bishops were excluded from the Lords, a popular revolution had already taken place. There were four major areas in which the popular voice expressed itself in the period under discussion. There were anti-episcopal riots in London. Hundreds of petitions came to Parliament from all over the country demanding that the bishops be removed from their temporal jurisdictions. Anti-prelatical sentiment was spread by means of pamphlets during the great pamphlet war of 1641. In Parliament, the anti-episcopal leadership wedded their own cause of constitutional reform to the popular cause against the bishops. In the end, the combination of these four factors resulted in the successful passage of laws needed to deprive the episcopate of their constitutional right to sit in Parliament. The anti-episcopal drive of 1640-1642 had its roots in the popular antipathy towards the episcopal office. The bishops were deprived of their voice in Parliament because the English people wanted them removed from the Lords. The English Revolution had already begun.

description: The vacuum expectation value of the fermionic current is evaluated for a massive spinor field in spacetimes with an arbitrary number of toroidally compactified spatial dimensions in presence of a constant gauge field. By using the Abel-Plana type summation formula and the zeta function technique we present the fermionic current in two different forms. Non-trivial topology of the background spacetime leads to the Aharonov-Bohm effect on the fermionic current induced by the gauge field. The current is a periodic function of the magnetic flux with the period equal to the flux quantum. In the absence of the gauge field it vanishes for special cases of untwisted and twisted fields. Applications of the general formulae to Kaluz-Klein type models and to cylindrical and toroidal carbon nanotubes are given. In the absence of magnetic flux the total fermionic current in carbon nanotubes vanishes, due to the cancellation of contributions from two different sublattices of the graphene hexagonal lattice.

description: Starting from Wilson's action, we calculate strong coupling series for the Polyakov loop susceptibility in lattice gauge theories for various small N_τin the thermodynamic limit. Analysing the series with Padé approximants, we estimate critical couplings and exponents for the deconfinement phase transition. For SU(2) pure gauge theory our results agree with those from Monte-Carlo simulations within errors, which for the coarser N_τ=1,2 lattices are at the percent level. For QCD we include dynamical fermions via a hopping parameter expansion. On a N_τ=1 lattice with N_f=1,2,3, we locate the second order critical point where the deconfinement transition turns into a crossover. We furthermore determine the behaviour of the critical parameters with finite chemical potential and find the first order region to shrink with growing μ. Our series moreover correctly reflects the known Z(N) transition at imaginary chemical potential.

description: Motivated by a recent conjecture by Hernandez and Leclerc [arXiv:0903.1452], we embed a Fomin-Zelevinsky cluster algebra [arXiv:math/0104151] into the Grothendieck ring R of the category of representations of quantum loop algebras U_q(Lg) of a symmetric Kac-Moody Lie algebra g, studied earlier by the author via perverse sheaves on graded quiver varieties [arXiv:math/9912158]. Graded quiver varieties controlling the image can be identified with varieties which Lusztig used to define the canonical base. The cluster monomials form a subset of the base given by the classes of simple modules in R, or Lusztig's dual canonical base. The positivity and linearly independence (and probably many other) conjectures of cluster monomials [arXiv:math/0104151] follow as consequences, when there is a seed with a bipartite quiver. Simple modules corresponding to cluster monomials factorize into tensor products of `prime' simple ones according to the cluster expansion.

description: We consider the question of how to distinguish quantum from classical transport through nanostructures. To address this issue we have derived two inequalities for temporal correlations in nonequilibrium transport in nanostructures weakly coupled to leads. The first inequality concerns local charge measurements and is of general validity; the second concerns the current flow through the device and is relevant for double quantum dots. Violation of either of these inequalities indicates that physics beyond that of a classical Markovian model is occurring in the nanostructure.

Development of the optic nerve head and foveation strategies in infants and young children with infantile nystagmus
Creators: name: Purohit, Ravi
Publisher: name: University of Leicester
Year: 2022
Subjects: Uncategorized

description: The three aims of this study were to:• Investigate the postnatal development of the optic nerve head (ONH) in infants and children with albinism, isolated infantile nystagmus (IIN) and achromatopsia against normal controls.• Investigate the asymmetry of ONH development in the four groups.• Explore the development of foveation strategy in albinism and IIN.Methods:Hand-held optical coherence (HH-OCT) tomography was used to image the ONH from 81 patients with albinism, 73 with IIN and 14 with achromatopsia and analysed using ImageJ, and statistically modelled using fractional polynomial regression. Child friendly stimuli were created to obtain eye movement traces and were correlated using LASSO regression and mixed linear models to foveal OCT parameters.Results:The disk width in albinism was wider than controls whereas IIN was consistent with controls, and in achromatopsia the disk was narrower than controls. In both albinism and IIN groups developed shallower narrower cups and larger nasal and temporal rim areas in the first 2 years of life. The optic cup in achromatopsia was shallower and narrower at birth, developing consistently with the control group. The nasal rim was larger at birth but normalised in the first 2 years of life, whereas the temporal rim was consistent with the control group throughout development. Inter ocular asymmetry of the ONH was subtle in the control group, but fewer asymmetric parameters were found in the albinism and IIN groups. In Both albinism and IIN measures of amplitude decreased with age. In IIN frequency increased with age. In both groups, the decrease in amplitude was associated to thickening of the inner segment at the fovea of the right eye. Parameters associated to frequency were positively correlated to parameters in the left eye in the photoreceptor layers. The beat direction was associated to thicker nasal outer segments of the right eye.Conclusion:The ONH in albinism and IIN has the appearance of crowded disks. This is associated to hypermetropia that is documented to be prevalent in these patient groups. In achromatopsia the appearance is similar to ONH hypoplasia. The development of these features is charted by the present study and gives important insight into the pathophysiology of these conditions. The retinal correlates of nystagmus characteristics allow for a greater understanding of why nystagmus develops. A theory pertaining to intra-retinal and inter-ocular rivalry is presented.

Our solutions include IIB backgrounds with no three form flux turned on, and arise as near horizon limits of branewave spacetimes. We show that there is a hypersurface in the space of these theories where an instability appears in the gravitational description, indicating a phase transition in the nonrelativistic field theory dual. We also present simple embeddings of duals for nonrelativistic critical points where the dynamical critical exponent can take many values z \neq 2.

description: In the technical world all the computer networks tend to become more and more complicated. The more difficulty here is to manage the routes and find which route is the best route. In this paper introduce a novel multiple constraints QoS multicast routing optimization algorithm in MANET called SRMBAR (Secure Reverse Multicast Bellman Ford Adhoc Routing) with the combination of ant colony optimization algorithm(ACO) that ensure Quality of service (QoS) guarantee by allowing reverse multicast routing on possible multiple paths between source and. The proposed SRMBAR and ACO can improve reliability of data transmission and optimize the maximum link utilization which achieves data integrity and then reduce the consumption of time and the transmission delay. Experimental results show that the reverse multicasting approach is efficient when compared with an existing algorithm, has promising performance in multicast traffic engineering and for evaluating the route stability in dynamic mobile networks.

Diagram spaces, diagram spectra, and spectra of units

Publisher: name: arXiv
Year: 2009
Subjects: subject: Algebraic Topology (math.AT)
subject: FOS: Mathematics

description: This article compares the infinite loop spaces associated to symmetric spectra, orthogonal spectra, and EKMM S-modules. Each of these categories of structured spectra has a corresponding category of structured spaces that receives the infinite loop space functor Ω^\infty. We prove that these models for spaces are Quillen equivalent and that the infinite loop space functors Ω^\infty agree. This comparison is then used to show that two different constructions of the spectrum of units gl_1 R of a commutative ring spectrum R agree.

description: We propose here a robust scheme to infer the physical parameters of compact stars from their f-mode gravitational wave signals. We first show that the frequency and the damping rate of f-mode oscillation of compact stars can be expressed in terms of universal functions of stellar mass and moment of inertia. By employing the universality in the f-mode one can then infer accurate values of the mass, the moment of inertia and the radius of a compact star. In addition, we demonstrate that our new scheme works well for both realistic neutron stars and quark stars, and hence provides a unifying way to infer the physical parameters of compact stars.

Temporal changes in south east Tasmanian saltmarshes

Subjects: Environmental management

description: Coastal saltmarshes are unique and highly productive ecosystems. They form a major part of the enclosed waterways of south east Tasmania, especially within the Pitt Water, Pipe Clay Lagoon and Ralphs Bay areas. The Pitt Water saltmarshes are acknowledged to be the most diverse and extensive of Tasmanian saltmarshes with extremely high floristic and faunal values, some recognised internationally while some remain unstudied. A study conducted in 1975 detailed the extent and vegetation community composition of the saltmarshes in the Pitt Water, Pipe Clay Lagoon and Ralphs Bay areas. More than 30 years since then, the change in these important ecological communities remained unstudied. Elsewhere in Australia and internationally, temporal studies of saltmarshes have reported substantial changes in morphology, extent and vegetation. This has led to several policy and management actions directed at conserving the function and values of saltmarshes. The objective of the present study was to investigate the spatial and temporal changes in saltmarshes mapped in 1975 to inform policy and planning concerning their management and conservation. Most saltmarshes have had losses in their areal extent, with nearly 17 hectares of area (5%) lost on the seaward side primarily due to coastal erosion. The saltmarsh shorelines have been eroding at about 6 cm to 20 cm a year, with erosion highest on the shorelines more exposed to wind-generated waves. Nearly 6% of the saltmarsh area had been lost due to land reclamation. While some area had been gained through accretion and landward transgression, it was less than a quarter of the saltmarsh area lost. Results for vegetation change show that low marsh plants, which are more adapted to waterlogging, have replaced long lived high marsh plants as the dominant vegetation community of the saltmarshes. A general shift of vegetation zones inland was observed, suggesting a response to sea level rise. Extensive areas within the marsh have been denuded of plant cover and have turned to salt pans/flats and “rotten spots” possibly affected by an increase in tidal inundation, increases in soil salinity related to climate change and increased nutrient inputs from irrigated land. These changes have several implications for the conservation of both the floristic and faunal values of saltmarshes and their contribution to the health and productivity of the coastal waterways. This study highlights a compelling need for strategic planning for the future conservation and management of these important coastal ecosystems in a time of change and contributes key information and methods to assist these efforts.
Regelfolgen im Kontext. Die kontextualistische Auflösung des Regelfolgeparadoxons

description: Die Dissertation versucht argumentativ das Regelfolgeparadoxon aufzulösen. Ausgehend vom sogenannten Regelfolgeparadoxon in den «Philosophischen Untersuchungen» Wittgensteins wird die Forschungsdiskussion dargestellt. Die beiden Ansätze des Kontextualismus erweitern den Fokus auf Wittgensteins «Über Gewissheit» als für die Thematik relevanten Text. Die Folgerungen aus den Erörterungen in «Über Gewissheit» führen zu einem Kontextbegriff, aus dem das Regelfolgeparadoxen gar nicht erst entstehen kann.

description: Strategy evaluation schemes are a crucial factor in any agent-based market model, as they determine the agents' strategy preferences and consequently their behavioral pattern. This study investigates how the strategy evaluation schemes adopted by agents affect their performance in conjunction with the market circumstances. We observe the performance of three strategy evaluation schemes, the history-dependent wealth game, the trend-opposing minority game, and the trend-following majority game, in a stock market where the price is exogenously determined. The price is either directly adopted from the real stock market indices or generated with a Markov chain of order $\le 2$. Each scheme's success is quantified by average wealth accumulated by the traders equipped with the scheme. The wealth game, as it learns from the history, shows relatively good performance unless the market is highly unpredictable. The majority game is successful in a trendy market dominated by long periods of sustained price increase or decrease. On the other hand, the minority game is suitable for a market with persistent zig-zag price patterns. We also discuss the consequence of implementing finite memory in the scoring processes of strategies. Our findings suggest under which market circumstances each evaluation scheme is appropriate for modeling the behavior of real market traders.

Simulating hydromagnetic processes in star formation: introducing ambipolar diffusion into an adaptive mesh refinement code

description: Given the importance of simulating hydromagnetic processes that impact star formation, we have earlier developed a 3D adaptive mesh approach that allows us to include hydromagnetic processes during the formation and evolution of cores, discs, and stars in observed regions of star formation. In this paper, we take the next step in this program - namely - to develop a modified version of the 3D adaptive mesh refinement (AMR) code FLASH in which the ambipolar diffusion of the magnetic field in poorly ionized molecular gas is implemented. We approach the problem using a single-fluid approximation to simplify numerical calculations. In this paper, we present a series of test cases including oblique isothermal and non--isothermal C-shocks. We also present a study of the quasi-static collapse of an initial uniform, self-gravitating, magnetized sphere that is initially supported by its magnetic field against collapse (i.e. magnetically subcritical). Applications to the collapse of a pre-stellar Bonnor-Ebert sphere are presented in a companion paper.

Phase transition for the mixing time of the Glauber dynamics for coloring regular trees

description: We prove that the mixing time of the Glauber dynamics for random k-colorings of the complete tree with branching factor b undergoes a phase transition at $k=b(1+o_b(1))/\ln{b}$. Our main result shows nearly sharp bounds on the mixing time of the dynamics on the complete tree with n vertices for $k=Cb/\ln{b}$ colors with constant C. For $C\geq1$ we prove the mixing time is $O(n^{1+o_b(1)}\ln{n})$. On the other side, for $C<1$ the mixing time experiences a slowing down; in particular, we prove it is $O(n^{1/C+o_b(1)}\ln{n})$ and $Ω(n^{1/C-o_b(1)})$. The critical point C=1 is interesting since it coincides (at least up to first order) with the so-called reconstruction threshold which was recently established by Sly. The reconstruction threshold has been of considerable interest recently since it appears to have close connections to the efficiency of certain local algorithms, and this work was inspired by our attempt to understand these connections in this particular setting.

Frustrated local moment models for Fe-pnictide magnetism

description: The low energy spin excitations of the Fe pnictide parent compounds have been determined by inelastic neutron scattering and interpreted within the local moment J_1a,b-J_2 Heisenberg model with orthorhombic symmetry. This has led to alternative exchange models that strongly differ in the size of anisotropy. Although the compounds are itinerant the localised spin model can explain basic features of the excitations. The inherent frustration of this model leads to quantum fluctuations and possible moment reduction. We investigate this question in detail using spin wave approximation and partly exact diagonalisation Lanczos calculations for finite clusters. We find that the orthorhombic anisotropy stabilizes the columnar AF phase and its moment. For the exchange models proposed from inelastic neutron scattering we can exclude a strong influcence of frustration on the moment size. We also investigate dependence of magnetisation and susceptibility on field and temperature.
