Trauma, memory and landscape in Queensland: women writing ‘a new alphabet of moss and water’

The cultural association of Queensland with a condition of imagination or unreality has a strong history. Queensland has always ‘retained much of its quality as an abstraction, an idea’, asserts Thea Astley in her famous essay on the state\u27s identity (Astley 1976: 263). In one of the most quoted descriptions of Queensland\u27s literary representation, Pat Buckridge draws attention to its ‘othering’, suggesting that Queensland possesses ‘a different sense of distance, different architecture, a different apprehension of time, a distinctive preoccupation with personal eccentricity, and . . . a strong sense of cultural antitheses’ (1976: 30). Rosie Scott comes closest to the concerns of this present article when she asserts that this so-called difference ‘is definitely partly to do with the landscape. In Brisbane, for instance, the rickety old wooden Queenslanders drenched in bougainvillea, the palms, the astounding number of birds even in Red Hill where I lived, the jacarandas, are all unique in Australia’ (quoted in Sheahan-Bright and Glover 2002: xv). For Vivienne Muller, Buckridge\u27s ‘cultural antitheses’ are most clearly expressed in precisely this interpretation of Queensland as a place somewhere between imagined wilderness and paradise (2001: 72). Thus, as Gillian Whitlock suggests, such differences are primarily fictional constructs that feed ‘an image making process founded more on nationalist debates about city and bush, centre and periphery, the Southern states versus the Deep North than on any “real” sense of regionalism’ (quoted in Muller 2001: 80). Queensland, in this reading, is subject to the Orientalist discourse of an Australian national identity in which the so-called civilisation of the south-eastern urban capitals necessitates a dark ‘other’. I want to draw out this understanding of the landscape as it is imagined in Queensland women\u27s writing. Gail Reekie (1994: 8) suggests that, ‘Women\u27s sense of place, of region, is powerfully constructed by their marginality to History.’ These narratives do assert Queensland\u27s ‘difference’, but as part of an articulation of psychological extremity experienced by those living on the edges of a simultaneously ideological and geographically limited space. The Queensland landscape, I argue, is thus used as both setting for and symbol of traumatic experience
Reality of the quantum state: A new proof in terms of protective measurements

The ontological model framework provides a rigorous approach to address the question of whether the quantum state is ontic or epistemic. When considering only conventional projective measurements, auxiliary assumptions are always needed to prove the reality of the quantum state in the framework. For example, the Pusey-Barrett-Rudolph theorem is based on an additional preparation independence assumption. In this paper, we give a new proof of psi-ontology in terms of protective measurements in the ontological model framework. The proof does not rely on auxiliary assumptions, and it also applies to deterministic theories such as the de Broglie-Bohm theory. In addition, we give a simpler argument for psi-ontology beyond the framework, which is based on protective measurements and a weaker criterion of reality. The argument may be also appealing for those people who favor an anti-realist view of quantum mechanics
Cumulative culture in nonhumans: overlooked findings from Japanese monkeys?

Cumulative culture, generally known as the increasing complexity or efficiency of cultural behaviors additively transmitted over successive generations, has been emphasized as a hallmark of human evolution. Recently, reviews of candidates for cumulative culture in nonhuman species have claimed that only humans have cumulative culture. Here, we aim to scrutinize this claim, using current criteria for cumulative culture to re-evaluate overlooked qualitative but longitudinal data from a nonhuman primate, the Japanese monkey (Macaca fuscata). We review over 60 years of Japanese ethnography of Koshima monkeys, which indicate that food-washing behaviors (e.g., of sweet potato tubers and wheat grains) seem to have increased in complexity and efficiency over time. Our reassessment of the Koshima ethnography is preliminary and nonquantitative, but it raises the possibility that cumulative culture, at least in a simple form, occurs spontaneously and adaptively in other primates and nonhumans in nature
Isomap nonlinear dimensionality reduction and bimodality of Asian monsoon convection

It is known that the empirical orthogonal function method is unable to detect possible nonlinear structure in climate data. Here, isometric feature mapping (Isomap), as a tool for nonlinear dimensionality reduction, is applied to 1958–2001 ERA-40 sea-level pressure anomalies to study nonlinearity of the Asian summer monsoon intraseasonal variability. Using the leading two Isomap time series, the probability density function is shown to be bimodal. A two-dimensional bivariate Gaussian mixture model is then applied to identify the monsoon phases, the obtained regimes representing enhanced and suppressed phases, respectively. The relationship with the large-scale seasonal mean monsoon indicates that the frequency of monsoon regime occurrence is significantly perturbed in agreement with conceptual ideas, with preference for enhanced convection on intraseasonal time scales during large-scale strong monsoons. Trend analysis suggests a shift in concentration of monsoon convection, with less emphasis on South Asia and more on the East China Sea
A mathematical analysis of rebound in a target-mediated drug disposition model: I.Without feedback.

We consider the possibility of free receptor (antigen/cytokine) levels rebounding to higher than the baseline level after one or more applications of an antibody drug using a target-mediated drug disposition model. Using geometry and dynamical systems analysis, we show that rebound will occur if and only if the elimination rate of the drug-receptor product is slower than the elimination rates of the drug and of the receptor. We also analyse the magnitude of rebound through approximations and simulations and demonstrate that it increases if the drug dose increases or if the difference between the elimination rate of the drug-receptor product and the minimum of the elimination rates of the drug and of the receptor increases
Essential competencies in prescribing : A first european cross‐sectional study among 895 final‐year medical students

European medical students should have acquired adequate prescribing competencies before graduation, but it is not known whether this is the case. In this international multicenter study, we evaluated the essential knowledge, skills, and attitudes in clinical pharmacology and therapeutics (CPT) of final‐year medical students across Europe. In a cross‐sectional design, 26 medical schools from 17 European countries were asked to administer a standardized assessment and questionnaire to 50 final‐year students. Although there were differences between schools, our results show an overall lack of essential prescribing competencies among final‐year students in Europe. Students had a poor knowledge of drug interactions and contraindications, and chose inappropriate therapies for common diseases or made prescribing errors. Our results suggest that undergraduate teaching in CPT is inadequate in many European schools, leading to incompetent prescribers and potentially unsafe patient care. A European core curriculum with clear learning outcomes and assessments should be urgently developed
Masses of excited heavy baryons in the relativistic quark-diquark
  picture

The mass spectra of the excited heavy baryons consisting of two light (u,d,s)
and one heavy (c,b) quarks are calculated in the heavy-quark--light-diquark
approximation within the constituent quark model. The light quarks, forming the
diquark, and the light diquark in the baryon are treated completely
relativistically. The expansion in v/c up to the second order is used only for
the heavy (b and c) quarks. The internal structure of the diquark is taken into
account by inserting the diquark-gluon interaction form factor. An overall good
agreement of the obtained predictions with available experimental data is
found.Comment: 13 pages; changed title; added Table VIII, note on new experimental

Terrestrial and submarine evidence for the extent and timing of the Last Glacial Maximum and the onset of deglaciation on the maritime-Antarctic and sub-Antarctic islands

This paper is the maritime and sub–Antarctic contribution to the Scientific Committee for Antarctic Research (SCAR) Past Antarctic Ice Sheet Dynamics (PAIS) community Antarctic Ice Sheet reconstruction. The overarching aim for all sectors of Antarctica was to reconstruct the Last Glacial Maximum (LGM) ice sheet extent and thickness, and map the subsequent deglaciation in a series of 5000 year time slices. However, our review of the literature found surprisingly few high quality chronological constraints on changing glacier extents on these timescales in the maritime and sub–Antarctic sector. Therefore, in this paper we focus on an assessment of the terrestrial and offshore evidence for the LGM ice extent, establishing minimum ages for the onset of deglaciation, and separating evidence of deglaciation from LGM limits from those associated with later Holocene glacier fluctuations. Evidence included geomorphological descriptions of glacial landscapes, radiocarbon dated basal peat and lake sediment deposits, cosmogenic isotope ages of glacial features and molecular biological data. We propose a classification of the glacial history of the maritime and sub–Antarctic islands based on this assembled evidence. These include: (Type I) islands which accumulated little or no LGM ice; (Type II) islands with a limited LGM ice extent but evidence of extensive earlier continental shelf glaciations; (Type III) seamounts and volcanoes unlikely to have accumulated significant LGM ice cover; (Type IV) islands on shallow shelves with both terrestrial and submarine evidence of LGM (and/or earlier) ice expansion; (Type V) Islands north of the Antarctic Polar Front with terrestrial evidence of LGM ice expansion; and (Type VI) islands with no data. Finally, we review the climatological and geomorphological settings that separate the glaciological history of the islands within this classification scheme
Sets of finite perimeter and the Hausdorff-Gauss measure on the Wiener
  space

In Euclidean space, the integration by parts formula for a set of finite
perimeter is expressed by the integration with respect to a type of surface
measure. According to geometric measure theory, this surface measure is
realized by the one-codimensional Hausdorff measure restricted on the reduced
boundary and/or the measure-theoretic boundary, which may be strictly smaller
than the topological boundary. In this paper, we discuss the counterpart of
this measure in the abstract Wiener space, which is a typical
infinite-dimensional space. We introduce the concept of the measure-theoretic
boundary in the Wiener space and provide the integration by parts formula for
sets of finite perimeter. The formula is presented in terms of the integration
with respect to the one-codimensional Hausdorff-Gauss measure restricted on the
measure-theoretic boundary.Comment: There are no changes of the mathematical part from the first version;

The Baum-Connes conjecture for free orthogonal quantum groups

We prove an analogue of the Baum-Connes conjecture for free orthogonal
quantum groups. More precisely, we show that these quantum groups have a $
\gamma $-element and that $ \gamma = 1 $. It follows that free orthogonal
quantum groups are $ K $-amenable. We compute explicitly their $ K $-theory and
deduce in the unimodular case that the corresponding reduced $ C^* $-algebras
do not contain nontrivial idempotents. Our approach is based on the
reformulation of the Baum-Connes conjecture by Meyer and Nest using the
language of triangulated categories. An important ingredient is the theory of
monoidal equivalence of compact quantum groups developed by Bichon, De Rijdt
and Vaes. This allows us to study the problem in terms of the quantum group $
SU_q(2) $. The crucial part of the argument is a detailed analysis of the
equivariant Kasparov theory of the standard Podle\'s sphere.Comment: 34 pages, final versio
The soft supersymmetry breaking in D=5 supergravity compactified on
  S_1/Z_2 orbifolds

We study the origin of the supersymmetry breaking induced by the mediation of
gravity and the radion multiplet from the hidden to the visible brane in the
context of the N=2, D=5 supergravity compactified on S_1/Z_2 orbifolds. The
soft supersymmetry breaking terms for scalar masses, trilinear scalar couplings
and gaugino masses are calculated to leading order in the five dimensional
Newton's constant k_5^2 and the gravitino mass m_{3/2}. These are finite and
non-vanishing, with the scalar soft masses be non-tachyonic, and are all
expressed in terms of the gravitino mass and the length scale R of the fifth
dimension. The soft supersymmetry breaking parameters are thus correlated and
the phenomenological implications are discussed.Comment: 16 pages, 3 figures, 1 Table, final version to appear in Physics

The Jacobi matrices approach to Nevanlinna-Pick problems

A modification of the well-known step-by-step process for solving
Nevanlinna-Pick problems in the class of $\bR_0$-functions gives rise to a
linear pencil $H-\lambda J$, where $H$ and $J$ are Hermitian tridiagonal
matrices. First, we show that $J$ is a positive operator. Then it is proved
that the corresponding Nevanlinna-Pick problem has a unique solution iff the
densely defined symmetric operator $J^{-1/2}HJ^{-1/2}$ is self-adjoint and some
criteria for this operator to be self-adjoint are presented. Finally, by means
of the operator technique, we obtain that multipoint diagonal Pad\'e
approximants to a unique solution $\varphi$ of the Nevanlinna-Pick problem
converge to $\varphi$ locally uniformly in $\dC\setminus\dR$. The proposed
scheme extends the classical Jacobi matrix approach to moment problems and
Pad\'e approximation for $\bR_0$-functions.Comment: 24 pages; Section 5 is modifed; some typos are correcte
Implications of 3-step swimming patterns in bacterial chemotaxis

We recently found that marine bacteria Vibrio alginolyticus execute a cyclic
3-step (run- reverse-flick) motility pattern that is distinctively different
from the 2-step (run-tumble) pattern of Escherichia coli. How this novel
swimming pattern is regulated by cells of V. alginolyticus is not currently
known, but its significance for bacterial chemotaxis is self- evident and will
be delineated herein. Using an approach introduced by de Gennes, we calculated
the migration speed of a cell executing the 3-step pattern in a linear chemical
gradient, and found that a biphasic chemotactic response arises naturally. The
implication of such a response for the cells to adapt to ocean environments and
its possible connection to E. coli 's response are also discussed.Comment: 18 pages, 4 figures, submitted to biophysical journa
m_u+m_d From Isovector Pseudoscalar Sum Rules

We revisit the isovector pseudoscalar sum rule determination of m_u+m_d,
using families of finite energy sum rules known to be very accurately satisfied
in the isovector vector channel. The sum rule constraints are sufficiently
strong to allow a determination of both m_u+m_d and the excited resonance decay
constants. The corresponding Borel transformed sum rules are also very well
satisfied, providing a non-trivial consistency check on the treatment of direct
instanton contributions. We obtain [m_u+m_d](2 GeV)=7.8\pm 1.1 MeV (in the MS
bar scheme), only marginally compatible with the most recent sum rule
determinations, but in good agreement with recent unquenched lattice
extractions.Comment: 15 pages, 6 figure
The Riddle of Polarization in $B \to VV$ Transitions

Measurements of polarization fractions in $B \to VV$ transitions, with $V$ a
light vector meson, show that the longitudinal amplitude dominates in $B^0 \to
\rho^+ \rho^-$, $B^+ \to \rho^+ \rho^0$, and $B^+ \to \rho^0 K^{*+}$ decays and
not in the penguin induced decays $B^0 \to \phi K^{*0}$, $B^+ \to \phi K^{*+}$.
We study the effect of rescattering mediated by charmed resonances, finding
that in $B \to \phi K^*$ it can be responsible of the suppression of the
longitudinal amplitude. For the decay $B \to \rho K^*$ we find that the
longitudinal fraction cannot be too large without invoking new effects.Comment: LaTex, 14 pages, 3 figure
Stau-catalyzed $^6$Li Production in Big-Bang Nucleosynthesis

If the gravitino mass is in the region from a few GeV to a few 10's GeV, the
scalar lepton X such as stau is most likely the next lightest supersymmetry
particle. The negatively charged and long-lived X^- may form a Coulomb bound
state (A X) with a nucleus A and may affect the big-bang nucleosynthesis
through catalyzed fusion process. We calculate a production cross section of
Li6 from the catalyzed fusion (He4 X^-) + d \to Li6 + X^- by solving the
Schr\"{o}dinger equation exactly for three-body system of He4, d, and X. We
utilize the state-of-the-art coupled-channel method, which is known to be very
accurate to describe other three-body systems in nuclear and atomic reactions.
The importance of the use of appropriate nuclear potential and the exact
treatment of the quantum tunneling in the fusion process are emphasized. We
find that the astrophysical S-factor at the Gamow peak corresponding to T=10
keV is 0.038 MeV barn. This leads to the Li6 abundance from the catalyzed
process as Li6|_{CBBN}\simeq 4.3\times 10^{-11} (D/2.8\times 10^{-5})
([n_{X^-}/s]/10^{-16}) in the limit of long lifetime of X. Particle physics
implication of this result is also discussed.Comment: 16 pages, 7 figure
Status of the two-Higgs-doublet model of type II

We determine the allowed parameter space of the CP-conserving
two-Higgs-doublet model (2HDM) of type II with a softly broken Z_2 symmetry.
Our analysis includes theoretical constraints from vacuum stability and
perturbativity as well as experimental constraints from signal strengths of the
126 GeV Higgs boson, the non-observation of additional Higgs resonances and
electroweak precision and flavour observables. If the 126 GeV resonance is
interpreted as the light CP-even Higgs boson of the 2HDM our analysis shows
that scenarios where the couplings of this boson deviate substantially from
those of the SM Higgs boson are disfavoured at one standard deviation and
completely excluded for small values of tan(beta). We also discuss bounds on
the masses of the heavy 2HDM Higgs bosons and their implications for the
possible decay modes of these particles. We find that the region in which both
non-standard neutral Higgs bosons are simultaneously lighter than 300 GeV is
excluded at two standard deviations
The nature of LINER galaxies: Ubiquitous hot old stars and rare
  accreting black holes

Galaxies, which often contain ionised gas, sometimes also exhibit a so-called
low-ionisation nuclear emission line region (LINER). For 30 years this was
attributed to a central mass-accreting supermassive black hole (AGN) of low
luminosity, making LINER galaxies the largest AGN-sub-population, dominating in
numbers over higher luminosity Seyfert galaxies and quasars. This, however,
poses a serious problem. While the inferred energy balance is plausible, many
LINERs clearly do not contain any other independent signatures of an AGN. Using
integral field spectroscopic data from the CALIFA survey, we aim at comparing
the observed radial surface brightness profiles with what is expected from
illumination by an AGN. Essential for this analysis is a proper extraction of
emission-lines, especially weak lines such as the Balmer Hb line which is
superposed on an absorption trough. To accomplish this, we use the GANDALF code
which simultaneously fits the underlying stellar continuum and emission lines.
We show for 48 galaxies with LINER-like emission, that the radial emission-line
surface brightness profiles are inconsistent with ionisation by a central
point-source and hence cannot be due to an AGN alone. The most probable
explanation for the excess LINER-like emission is ionisation by evolved stars
during the short but very hot and energetic phase known as post-AGB. This leads
us to an entirely new interpretation. Post-AGB stars are ubiquitous and their
ionising effect should be potentially observable in every galaxy with gas
present and stars older than ~1 Gyr, unless a stronger radiation field from
young hot stars or an AGN outshines them. This means that galaxies with
LINER-like emission are in fact not a class defined by a property, but rather
by the absence of a property. It also explains why LINER emission is observed
mostly in massive galaxies with old stars and little star formation.Comment: 8 pages, 7 figure
Giant magnon solution and dispersion relation in string theory in AdS_3
  x S^3 x T^4 with mixed flux

We address the question about the exact form of the dispersion relation for
light-cone string excitations in string theory in AdS3 x S3 x T4 with mixed R-R
and NS-NS 3-form fluxes. The analogy with string theory in AdS5 x S5 suggests
that in addition to the data provided by the perturbative near-BMN expansion
and the symmetry algebra considerations there is also another source of
information about the dispersion relation -- the semiclassical giant magnon
solution. In earlier work in arXiv:1303.1037 and arXiv:1304.4099 it was found
that the symmetry algebra constraints consistent with perturbative expansion do
not completely determine the form of the dispersion relation. The aim of the
present paper is to fix it by constructing a generalization of the known dyonic
giant magnon soliton on S3 to the presence of a non-zero NS-NS flux described
by a WZ term in the string action. We find that the angular momentum of this
soliton gets shifted by a term linear in world-sheet momentum. We also discuss
the symmetry algebra of the string light-cone S-matrix and show that the exact
dispersion relation, which should have the correct perturbative BMN and
semiclassical giant magnon limits, should also contain such a linear momentum
term. The simplicity of the resulting bound-state picture provides a strong
argument in favour of this dispersion relation.Comment: 32 pages. v2: minor comments adde
Entanglement and Correlations near Extremality: CFTs dual to
  Reissner-Nordstr\"om AdS${}_5$

We use the AdS/CFT correspondence to study models of entanglement and
correlations between two $d=4$ CFTs in thermofield double states at finite
chemical potential. Our bulk spacetimes are planar Reissner-Nordstr\"om AdS
black holes. We compute both thermo-mutual information and the two-point
correlators of large-dimension scalar operators, focussing on the
small-temperature behavior -- an infrared limit with behavior similar to that
seen at large times. The interesting feature of this model is of course that
the entropy density remains finite as $T \rightarrow 0$ while the bulk geometry
develops an infinite throat. This leads to a logarithmic divergence in the
scale required for non-zero mutual information between equal-sized strips in
the two CFTs, though the mutual information between one entire CFT and a
finite-sized strip in the other can remain non-zero even at $T=0$. Furthermore,
despite the infinite throat, there can be extremally charged operators for
which the two-point correlations remain finite as $T \rightarrow 0$. This
suggests an interestingly mixed picture in which some aspects of the
entanglement remain localized on scales set by the chemical potential, while
others shift to larger and larger scales. We also comment on implications for
the localized-quasiparticle picture of entanglement.Comment: 29+8 pages, 10 figure
