description: In the 1950's Wigner and collaborators provided an explanation for the spectrum of hadronic excitations in terms of Random Matrix Theory. In the 1980's it was understood that some hadronic spectral properties were generic to systems whose classical limit is chaotic. We use string theory to demonstrate explicitly how, under very general conditions, recent holographic models of strong interactions have a spectrum compatible with Wigner's conjecture.

Quantum reading of digital memory with non-Gaussian entangled light

description: It has been shown recently (Phys. Rev. Lett. 106, 090504 (2011)) that entangled light with Einstein-Podolsky-Rosen (EPR) correlations retrieves information from digital memory better than any classical light. In identifying this, a model of digital memory with each cell consisting of reflecting medium with two reflectivities (each memory cell encoding the binary numbers 0 or 1) is employed. The readout of binary memory essentially corresponds to discrimination of two Bosonic attenuator channels characterized by different reflectivities. The model requires an entire mathematical paraphernalia of continuous variable Gaussian setting for its analysis, when arbitrary values of reflectivities are considered. Here we restrict to a basic quantum read-out mechanism with non-Gaussian entangled states of light, with the binary channels to be discriminated being ideal memory characterized by reflectivity one i.e., an identity channel and thermal noise channel, where the signal light illuminating the memory location gets completely lost (zero reflectivity) and only a white thermal noise hitting the upper side of the memory reaches the decoder. We compare the quantum reading efficiency of entangled light with any classical source of light in this model. We show that entangled transmitters offer better reading performance than any classical transmitters of light in the regime of low signal intensity.

description: We study the excitonic phase transition in a system of the conduction band electrons and valence band holes described by the three-dimensional (3D) extended Falicov-Kimball (EFKM) model with the tunable Coulomb interaction $U$ between both species. By lowering the temperature, the electron-hole system may become unstable with respect to the formation of the excitons, i.e, electron-hole pairs at temperature $T=T_Δ$, exhibiting a gap $Δ$ in the particle excitation spectrum. To this end we implement the functional integral formulation of the EFKM, where the Coulomb interaction term is expressed in terms of U(1) phase variables conjugate to the local particle number, providing a useful representation of strongly correlated system. The effective action formalism allows us to formulate a problem in the phase-only action in the form of the quantum rotor model and to obtain analytical formula for the critical lines and other quantities of physical interest like charge gap, chemical potential and the correlation length.

Tailoring Anderson localization by disorder correlations in 1D speckle potentials

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)

description: We study Anderson localization of single particles in continuous, correlated, one-dimensional disordered potentials. We show that tailored correlations can completely change the energy-dependence of the localization length. By considering two suitable models of disorder, we explicitly show that disorder correlations can lead to a nonmonotonic behavior of the localization length versus energy. Numerical calculations performed within the transfer-matrix approach and analytical calculations performed within the phase formalism up to order three show excellent agreement and demonstrate the effect. We finally show how the nonmonotonic behavior of the localization length with energy can be observed using expanding ultracold-atom gases.

description: We introduce and analyse an individual-based evolutionary model, in which a population of genetically diverse organisms compete with each other for limited resources. Through theoretical analysis and stochastic simulations, we show that the model exhibits a pattern-forming instability which is highly amplified by the effects of demographic noise, leading to the spontaneous formation of genotypic clusters. This mechanism supports the thesis that stochasticity has a central role in the formation and coherence of species.

description: We investigate the metallic transport in the organic superconductor (TMTSF)2PF6 under pressure within the framework of the spin density wave theory in the proximity of a Peierls quantum critical point (QCP). We use a simple transport model of hot and cold regions around the Fermi surface, driven by the proximity to the QCP in order to provide a template to fit the experimental results. Successful agreement with the data comforts the interpretation of extended criticality around the antiferromagnetic QCP in the normal phase of quasi one-dimensional organic superconductors.

description: We consider an analogue of the Kac random walk on the special orthogonal group $SO(N)$, in which at each step a random rotation is performed in a randomly chosen 2-plane of $\bR^N$. We obtain sharp asymptotics for the rate of convergence in total variance distance, establishing a cut-off phenomenon in the large $N$ limit. In the special case where the angle of rotation is deterministic this confirms a conjecture of Rosenthal \cite{Rosenthal}. Under mild conditions we also establish a cut-off for convergence of the walk to stationarity under the $L^2$ norm. Depending on the distribution of the randomly chosen angle of rotation, several surprising features emerge. For instance, it is sometimes the case that the mixing times differ in the total variation and $L^2$ norms. Our estimates use an integral representation of the characters of the special orthogonal group together with saddle point analysis.

description: Glycation of whey proteins results in food-grade composites with modified physicochemical properties. Here, the reaction between glucose and bovine serum albumin (BSA) is promoted under wet-heating conditions. The glycated protein is characterized in depth and compared to the native counterpart and the impact of glycation on properties like net surface charge, particle size and surface hydrophobicity are observed. Conjugation with glucose reduced the surface hydrophobicity of BSA but the interactions between albumin and curcumin became stronger, which contradicts the direct relationship between curcumin binding affinity and protein surface hydrophobicity described in the literature. Nonetheless, curcumin was still capable of quenching the intrinsic fluorescence of the protein after conjugation with glucose and leads to the conclusion that curcumin and BSA interact in a different manner upon glycation. This thesis also depicts mucin as a forthcoming model in the study of nanoparticle interactions with intestinal mucus and glycation posed no effect on such interactions.

description: We give a generalization of the concept of near-symplectic structures to 2n dimensions. According to our definition, a closed 2-form ωon a 2n-manifold M is near-symplectic, if it is symplectic outside a submanifold Z of codimension 3, where ω^{n-1} vanishes. This extends the concept known in dimension 4. We depict how this notion relates to near-symplectic 4-manifolds and broken Lefschetz fibrations via some examples. We define a generalized broken Lefschetz fibration, or BLF, as a singular map with indefinite folds and Lefschetz-type singularities. We show that given such a map on a 2n-manifold over a symplectic base of codimension 2, then the total space carries such a near-symplectic structure, whose singular locus corresponds precisely to the singularity set of the fibration. A second part studies the geometry around the codimension--3 singular locus Z. We describe a splitting property of the normal bundle N_Z that is also present in dimension four. A tubular neighbourhood for Z is provided, which has as a corollary a Darboux-type theorem for near-symplectic forms.

description: We develop a kinetic equation description of Coulomb drag between ballistic one-dimensional electron systems, which enables us to demonstrate that equilibration processes between right- and left-moving electrons are crucially important for establishing dc drag. In one-dimensional geometry, this type of equilibration requires either backscattering near the Fermi level or scattering with small momentum transfer near the bottom of the electron spectrum. Importantly, pairwise forward scattering in the vicinity of the Fermi surface alone is not sufficient to produce a nonzero dc drag resistivity $ρ_{\rm D}$, in contrast to a number of works that have studied Coulomb drag due to this mechanism of scattering before. We show that slow equilibration between two subsystems of electrons of opposite chirality, "bottlenecked" by inelastic collisions involving cold electrons near the bottom of the conduction band, leads to a strong suppression of Coulomb drag, which results in an activation dependence of $ρ_{\rm D}$ on temperature---instead of the conventional power law. We demonstrate the emergence of a drag regime in which $ρ_{\rm D}$ does not depend on the strength of interwire interactions, while depending strongly on the strength of interactions inside the wires.

A sociological study of Indigenous adolescent offending in Queensland

subject: Sociology of migration, ethnicity and multiculturalism

subject: Criminological theories

description: The aim of this thesis is to achieve a better understanding of Indigenous adolescent offending in Queensland. Although much has been written on this topic, there has been no research into patterns of Indigenous adolescent offending across urban, rural and remote areas in Queensland, or anywhere else in Australia. Similarly, no studies have compared a wide range of demographic, social, economic and cultural factors with rates of Indigenous adolescent offences. This study shows that there are discernible differences in rates and patterns of Indigenous adolescent offences across different geographical areas of Queensland. The similarities and differences are explained using a sociological perspective, with particular emphasis on the work of Jock Young. The study is based on offence data supplied by the Queensland Police Service for 110 Local Government Areas (LGAs) in Queensland for the period from 1 July 2005 to 30 June 2007. The LGAs were further categorised according to geographical and social characteristics, resulting in 27 ‘urban’, 49 ‘rural’, 19 ‘Aboriginal’, and 15 ‘Island’ councils or LGAs. After an initial comparison of Indigenous and non-Indigenous adolescent offending to put the study in context, Indigenous adolescent offending in the four categories of LGA was analysed according to the sex of the offender, the age of the offender, the type of offence committed, and the type of police action taken against the offender. Following on from this examination of rates and patterns of offending, correlation and regression analyses were used to elucidate relationships between Indigenous adolescent offending and various social, economic and cultural variables. The study found that rates and patterns of Indigenous adolescent offences varied greatly among the four categories of LGA, with offending being most pronounced in Aboriginal councils and least in Island councils. This pattern persisted when offending was analysed according to age, sex, type of offence, and type of police action. Nevertheless, a sociological interpretation of the results suggests that particular forms of structural exclusion and relative deprivation associated with Indigeneity underlie the high rates of Indigenous adolescent offences in Queensland, although they manifest in different ways depending on the type of Indigenous community. Following on from this, it is argued that socioeconomic status alone cannot account for the high overrepresentation of Indigenous adolescents in the Queensland criminal justice system. Despite the importance of the underlying factors mentioned above, the differences between Indigenous communities and the variations in rates and patterns of offending mean that the approaches taken to address this problem must be tailored to suit each community.

description: When an accretion disk falls prey to the runaway instability, a large portion of its mass is devoured by the black hole within a few dynamical times. Despite decades of effort, it is still unclear under what conditions such an instability can occur. The technically most advanced relativistic simulations to date were unable to find a clear sign for the onset of the instability. In this work, we present three-dimensional relativistic hydrodynamics simulations of accretion disks around black holes in dynamical space-time. We focus on the configurations that are expected to be particularly prone to the development of this instability. We demonstrate, for the first time, that the fully self-consistent general relativistic evolution does indeed produce a runaway instability.

description: Large-N_c QCD matter at intermediate baryon density and low temperatures has been conjectured to be in the so-called quarkyonic phase, i.e., to have a quark Fermi surface and on top of it a confined spectrum of excitations. It has been suggested that the presence of the quark Fermi surface leads to a homogeneous phase with restored chiral symmetry, which is unstable towards creating condensates breaking both the chiral and translational symmetry. Motivated by these exotic features, we investigate properties of cold baryonic matter in the single flavor Sakai-Sugimoto model searching for a holographic realization of the quarkyonic phase. We use a simplified mean-field description and focus on the regime of parametrically large baryon densities, of the order of the square of the 't Hooft coupling, as they turn out to lead to new physical effects similar to the ones occurring in the quarkyonic phase. One effect, the appearance of a particular marginally stable mode breaking translational invariance and linked with the presence of the Chern-Simons term in the flavor brane Lagrangian, is known to occur in the deconfined phase of the Sakai-Sugimoto model, but turns out to be absent here. The other, completely new phenomenon that we, preliminarily, study using strong simplifying assumptions are density-enhanced interactions of the flavor brane gauge field with holographically represented baryons. These seem to significantly affect the spectrum of vector and axial mesons and might lead to approximate chiral symmetry restoration in the lowest part of the spectrum, where the mesons start to qualitatively behave like collective excitations of the dense baryonic medium. We discuss the relevance of these effects for holographic searches of the quarkyonic phase and conclude with a discussion of various subtleties involved in constructing a mean-field holographic description of a dense baryonic medium.

description: We study the thermodynamics of quantum projective measurements by using the set up for the Jarzynski equality. We prove the fluctuations of energy change induced by measurements satisfy the Jarzynski equality, revealing that the quantum projective measurements perform a work on a measured system. When the system is brought into a thermal contact with a reservoir after measurements, the work done by projective measurements is totally dissipated in the form of heat from the system into the reservoir. Explicitly showing that the measurements always increase the total entropy, we prove the link between the second law of thermodynamics and the quantum measurement, and also provide a clue to the Landau-Lifshitz conjecture on the thermodynamic consequence of measurements.

description: ARIANNA (The Antarctic Ross Ice Shelf Antenna Neutrino Array) is a proposed 100 km^3 detector for ultra-high energy (above 10^17 eV) astrophysical neutrinos. It will study the origins of ultra-high energy cosmic rays by searching for the neutrinos produced when these cosmic rays interact with the cosmic microwave background. Over 900 independently operating stations will detect the coherent radio Cherenkov emission produced when astrophysical neutrinos with energy above 10^17 eV interact in the Antarctic Ross Ice Shelf. Each station will use 8 log periodic dipole antennas to look for short RF pulses, with the most important frequencies between 80 MHz and 1 GHz. By measuring the pulse polarization and frequency spectrum, the neutrino arrival direction can be determined. In one year of operation, the full array should observe a clear GZK neutrino signal, with different models predicting between 3 and 51 events, depending on the nuclear composition of the cosmic-rays and on the cosmic evolution of their sources.

description: In the framework of a simple quantum field theory describing the decay of a scalar state into two (pseudo)scalar ones we study the pole(s) motion(s) of its propagator: besides the expected pole on the second Riemann sheet, we find -- for a large enough coupling constant -- a second, additional pole on the first Riemann sheet below threshold, which corresponds to a stable state. We then perform a numerical study for a hadronic system in which a scalar particle couples to pions. We investigate under which conditions a stable state below the two-pion threshold can emerge. In particular, we study the case in which this stable state has a mass of 38 MeV, which corresponds to the recently claimed novel scalar state E(38). Moreover, we also show that the resonance $f_{0}(500)$ and the stable state E(38) could be two different manifestation of the same `object'. Finally, we also estimate the order of magnitude of its coupling to photons.

description: Let X be a translation invariant point process on the complex plane and let D be a bounded open set whose boundary has zero Lebesgue measure. We ask what does the point configuration obtained by taking the points of X outside D tell us about the point configuration inside D? We show that for the Ginibre ensemble, it determines the number of points in D. For the translation-invariant zero process of a planar Gaussian Analytic Function, we show that it determines the number as well as the centre of mass of the points in D. Further, in both models we prove that the outside says "nothing more" about the inside, in the sense that the conditional distribution of the inside points, given the outside, is mutually absolutely continuous with respect to the Lebesgue measure on its supporting submanifold.

description: A survey of the community of helminths in Emydura krefftii Gray in central and northern Queensland was undertaken. Then a detailed study of Sychnocotyle kholo Ferguson, Cribb and Smales, 1999, a newly described aspidogastrean parasite of E. krefftii, was conducted. The principal aim of this study was to examine the life history, fine morphology and phylogenetic relationships of this species. Specimens of Emydura krefftii were sampled from six coastal catchments from Cooktown to Bundaberg in northern and central Queensland. Concurrently data were collated on the community structure of helminths of E. krefftii. To examine the life history of S. kholo, molluscs were collected and examined for juvenile aspidogastreans from areas sampled for turtles and S. kholo eggs were collected from the faeces of collected turtles. The study of morphology of this helminth involved staining whole mounts and sections for light microscopy for gross morphology and examination of organ systems. Scanning electron microscopy was used to examine the outer surface of the worm in detail. For fine morphology of organs, transmission electron microscopy and confocal microscopy were applied. Finally characters were identified for a phylogenetic analysis and a data matrix was constructed and executed with Phylogenetic Analysis Using Parsimony (PAUP) software.

Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: Let $E$ be an elliptic curve defined over $\Q$ and with complex multiplication by $\mO_K$, the ring of integers in an imaginary quadratic field $K$. It is known that $E(\F_p)$ has a structure E(\F_p)\simeq \Z/d_p\Z \oplus \Z/e_p\Z. with $d_p|e_p$. We give an asymptotic formula for the average order of $e_p$, with improved error term, and upper bound estimate for the average of $d_p$.

A tunable coupler with ScS quantum point contact to mediate strong interaction between flux qubits

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: In this paper we propose a kind of quantum inductance couplers (QUINC) which represents a superconducting loop closed by ScS quantum point contact, operating in deep quantum low-temperature regime to provide tunable (Ising-type) ZZ interaction between flux qubits. This coupler is shown to be well tunable by an external control magnetic flux and to provide large inter-qubit interaction energies $|J/k_{\rm B}|\simeq1$ K thus being very promising as a qubit-coupling device in a quantum register as well as for studying fundamental low-temperature quantum phenomena. Some entanglement measures of a two-qubit system are analyzed as functions of inter-qubit interaction strength.

Citation analysis may severely underestimate the impact of clinical research as compared to basic research

description: Background: Citation analysis has become an important tool for research performance assessment in the medical sciences. However, different areas of medical research may have considerably different citation practices, even within the same medical field. Because of this, it is unclear to what extent citation-based bibliometric indicators allow for valid comparisons between research units active in different areas of medical research. Methodology: A visualization methodology is introduced that reveals differences in citation practices between medical research areas. The methodology extracts terms from the titles and abstracts of a large collection of publications and uses these terms to visualize the structure of a medical field and to indicate how research areas within this field differ from each other in their average citation impact. Results: Visualizations are provided for 32 medical fields, defined based on journal subject categories in the Web of Science database. The analysis focuses on three fields. In each of these fields, there turn out to be large differences in citation practices between research areas. Low-impact research areas tend to focus on clinical intervention research, while high-impact research areas are often more oriented on basic and diagnostic research. Conclusions: Popular bibliometric indicators, such as the h-index and the impact factor, do not correct for differences in citation practices between medical fields. These indicators therefore cannot be used to make accurate between-field comparisons. More sophisticated bibliometric indicators do correct for field differences but still fail to take into account within-field heterogeneity in citation practices. As a consequence, the citation impact of clinical intervention research may be substantially underestimated in comparison with basic and diagnostic research.

description: We consider the rank reduction problem for matroids: Given a matroid M and an integer k, find a minimum size subset of elements of M whose removal reduces the rank of M by at least k. When M is a graphical matroid this problem is the minimum k-cut problem, which admits a 2-approximation algorithm. In this paper we show that the rank reduction problem for transversal matroids is essentially at least as hard to approximate as the densest k-subgraph problem. We also prove that, while the problem is easily solvable in polynomial time for partition matroids, it is NP-hard when considering the intersection of two partition matroids. Our proof shows, in particular, that the maximum vertex cover problem is NP-hard on bipartite graphs, which answers an open problem of B. Simeone.
