Analysis on the minimal representation of O(p,q) -- III. ultrahyperbolic
  equations on R^{p-1,q-1}

For the group O(p,q) we give a new construction of its minimal unitary
representation via Euclidean Fourier analysis.
  This is an extension of the q = 2 case, where the representation is the mass
zero, spin zero representation realized in a Hilbert space of solutions to the
wave equation. The group O(p,q) acts as the Moebius group of conformal
transformations on R^{p-1, q-1}, and preserves a space of solutions of the
ultrahyperbolic Laplace equation on R^{p-1, q-1}.
  We construct in an intrinsic and natural way a Hilbert space of
ultrahyperbolic solutions so that O(p,q) becomes a continuous irreducible
unitary representation in this Hilbert space.
  We also prove that this representation is unitarily equivalent to the
representation on L^2(C), where C is the conical subvariety of the nilradical
of a maximal parabolic subalgebra obtained by intersecting with the minimal
nilpotent orbit in the Lie algebra of O(p,q)
Fourth Order Gradient Symplectic Integrator Methods for Solving the
  Time-Dependent Schr\"odinger Equation

We show that the method of splitting the operator ${\rm e}^{\epsilon(T+V)}$
to fourth order with purely positive coefficients produces excellent algorithms
for solving the time-dependent Schr\"odinger equation. These algorithms require
knowing the potential and the gradient of the potential. One 4th order
algorithm only requires four Fast Fourier Transformations per iteration. In a
one dimensional scattering problem, the 4th order error coefficients of these
new algorithms are roughly 500 times smaller than fourth order algorithms with
negative coefficient, such as those based on the traditional Ruth-Forest
symplectic integrator. These algorithms can produce converged results of
conventional second or fourth order algorithms using time steps 5 to 10 times
as large. Iterating these positive coefficient algorithms to 6th order also
produced better converged algorithms than iterating the Ruth-Forest algorithm
to 6th order or using Yoshida's 6th order algorithm A directly.Comment: 11 pages, 2 figures, submitted to J. Chem. Phy
NMR Quantum Computation: a Critical Evaluation

Liquid state nuclear magnetic resonance (NMR) techniques have produced some
spectacular successes in the construction of small quantum computers, and NMR
is currently by far the leading technology for quantum computation. There are,
however, a number of significant problems with any attempt to scale up the
technology to produce computers of any useful size. While it is probable that
some of these will be successfully sidestepped during the next few years, it is
unlikely that they will all be solved; thus current liquid state NMR techniques
are unlikely to provide a viable technology for practical quantum computation.Comment: Prepared for Fortschritte der Physik special issue, Experimental

Circular and linear magnetic birefringences in xenon at $\lambda = 1064$
  nm

The circular and linear magnetic birefringences corresponding to the Faraday
and the Cotton-Mouton effects, respectively, have been measured in xenon at
$\lambda = 1064$ nm. The experimental setup is based on time dependent magnetic
fields and a high finesse Fabry-Perot cavity. Our value of the Faraday effect
is the first measurement at this wavelength. It is compared to theoretical
predictions. Our uncertainty of a few percent yields an agreement at better
than 1$\sigma$ with the computational estimate when relativistic effects are
taken into account. Concerning the Cotton-Mouton effect, our measurement, the
second ever published at $\lambda = 1064$ nm, agrees at better than $1\sigma$
with theoretical predictions. We also compare our error budget with those
established for other experimental published values
Accurate gamma and MeV-electron track reconstruction with an ultra-low
  diffusion Xenon/TMA TPC at 10 atmospheres

We report the performance of a 10 atm Xenon/trimethylamine time projection
chamber (TPC) for the detection of X-rays (30 keV) and gamma-rays (0.511-1.275
MeV) in conjunction with the accurate tracking of the associated electrons.
When operated at such a high pressure and in 1%-admixtures, trimethylamine
(TMA) endows Xenon with an extremely low electron diffusion (1.3 +-0.13
mm-sigma (longitudinal), 0.8 +-0.15 mm-sigma (transverse) along 1 m drift)
besides forming a convenient Penning-Fluorescent mixture. The TPC, that houses
1.1 kg of gas in its active volume, operated continuously for 100 live-days in
charge amplification mode. The readout was performed through the recently
introduced microbulk Micromegas technology and the AFTER chip, providing a 3D
voxelization of 8mm x 8mm x 1.2mm for approximately 10 cm/MeV-long electron
tracks. This work was developed as part of the R&D program of the NEXT
collaboration for future detector upgrades in the search of the 0bbnu decay in
136Xe, specifically those based on novel gas mixtures. Therefore we ultimately
focus on the calorimetric and topological properties of the reconstructed
MeV-electron tracks
Solar science with the Atacama Large Millimeter/submillimeter Array - A
  new view of our Sun

The Atacama Large Millimeter/submillimeter Array (ALMA) is a new powerful
tool for observing the Sun at high spatial, temporal, and spectral resolution.
These capabilities can address a broad range of fundamental scientific
questions in solar physics. The radiation observed by ALMA originates mostly
from the chromosphere - a complex and dynamic region between the photosphere
and corona, which plays a crucial role in the transport of energy and matter
and, ultimately, the heating of the outer layers of the solar atmosphere. Based
on first solar test observations, strategies for regular solar campaigns are
currently being developed. State-of-the-art numerical simulations of the solar
atmosphere and modeling of instrumental effects can help constrain and optimize
future observing modes for ALMA. Here we present a short technical description
of ALMA and an overview of past efforts and future possibilities for solar
observations at submillimeter and millimeter wavelengths. In addition, selected
numerical simulations and observations at other wavelengths demonstrate ALMA's
scientific potential for studying the Sun for a large range of science cases.Comment: 73 pages, 21 figures ; Space Science Reviews (accepted December 10th,

The accretion dynamics of EX Lupi in quiescence:The star, the spot, and
  the accretion column

EX Lupi is a young star, prototype of EXor variables. Its spectrum is very
rich in emission lines, including many metallic lines. It has been also
proposed to have a close companion. We use the metallic emission lines to study
the accretion structures and to test the companion hypothesis. We analyse 54
spectra taken in 5 years of quiescence time. We study the line profile
variability and the radial velocity of the metallic emission lines. We use the
velocity signatures of different species with various excitation conditions and
their time dependency to track the dynamics associated to accretion. We observe
periodic velocity variations in the line components consistent with rotational
modulation. The modulation is stronger for lines with higher excitation
potentials. We propose that the narrow line components are produced in the
post-shock region, while the broad components originate in the more extended,
pre-shock material. All the emission lines suffer velocity modulation due to
the rotation of the star. The broad components are responsible for the
line-dependent veiling observed in EX Lupi. Rotationally-modulated
line-dependent veiling can explain the radial velocity signatures, making the
close-in companion hypothesis unnecessary. The accretion structure is locked to
the star and very stable during the 5 years of observations. Not all stars with
similar spectral types and accretion rates show the same metallic emission
lines, maybe related to differences in temperature and density in their
accretion structure(s). The contamination of photospheric lines by accretion
processes can be turned into a very useful tool to determine the innermost
details of the accretion channels in the proximities of the star. Emission
lines from very stable accretion columns will nevertheless be a very strong
limitation for the detection of companions by radial velocity in young stars.

Search for weakly decaying $\bar{\Lambda\mathrm{n}}$ and $\Lambda\Lambda
  $ exotic bound states in central Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ =
  2.76 TeV

We present results of a search for two hypothetical strange dibaryon states,
i.e. the H-dibaryon and the possible $\bar{\Lambda\mathrm{n}}$ bound state. The
search is performed with the ALICE detector in central (0-10%) Pb-Pb collisions
at $ \sqrt{s_{\rm{NN}}} = 2.76$ TeV, by invariant mass analysis in the decay
modes $\bar{\Lambda\mathrm{n}} \rightarrow \bar{\mathrm{d}} \pi^{+} $ and
H-dibaryon $\rightarrow \Lambda \mathrm{p} \pi^{-}$. No evidence for these
bound states is observed. Upper limits are determined at 99% confidence level
for a wide range of lifetimes and for the full range of branching ratios. The
results are compared to thermal, coalescence and hybrid UrQMD model
expectations, which describe correctly the production of other loosely bound
states, like the deuteron and the hypertriton.Comment: 19 pages, 5 captioned figures, 2 tables, authors from page 14,

Programming Robosoccer agents by modelling human behavior

The Robosoccer simulator is a challenging environment for artificial intelligence, where a human has to program a team of agents and introduce it into a soccer virtual environment. Most usually, Robosoccer agents are programmed by hand. In some cases, agents make use of Machine learning (ML) to adapt and predict the behavior of the opposite team, but the bulk of the agent has been preprogrammed. The main aim of this paper is to transform Robosoccer into an interactive game and let a human control a Robosoccer agent. Then ML techniques can be used to model his/her behavior from training instances generated during the play. This model will be used later to control a Robosoccer agent, thus imitating the human behavior. We have focused our research on low-level behavior, like looking for the ball, conducting the ball towards the goal, or scoring in the presence of opponent players. Results have shown that indeed, Robosoccer agents can be controlled by programs that model human play.Publicad
Policy delivery for low carbon energy infrastructure in the UK

The authors acknowledge the ESRC and the law firm Simpson and Marwick for supporting the conference.The ambition of this conference was to deliver a first examination of how policy is delivered in the context of low-carbon energy infrastructure in the UK. The UK has been developing policy in this area since 2002 (Heffron, 2013). Finally, as the decade passed, in November 2012 an Energy Bill was put before the UK Parliament. One of the chief purposes of this Energy Bill is to establish the right environment for new electricity generation infrastructure in the low-carbon sector. There is significant debate on how this will be achieved and, indeed, whether this piece of legislation will actually deliver this outcome. This conference aimed to examine the dynamics of policy delivery. Throughout the day, there was entertaining discussion as a variety of conference presenters provided interesting contributions on how to deliver such policy goals. In total, there were twelve speakers throughout the day representing the UK (University of Oxford, Pinsent Masons Law Firm, University of Stirling, University of Dundee and University of Aberdeen), and also those who provided lessons from abroad from the University of Copenhagen, Central European University, Milieu Ltd., Pillsbury Law Firm (Washington DC, US) and the Conservation Law Foundation (MA, US).PostprintPeer reviewe
Psychometric properties of reaction time based experimental paradigms measuring anxiety-related information-processing biases in children.

Theoretical frameworks highlight the importance of threat-related information-processing biases for understanding the emergence of anxiety in childhood. The psychometric properties of several tasks measuring these biases and their associations with anxiety were examined in an unselected sample of 9-year-old children (N=155). In each task, threat bias was assessed using bias scores reflecting task performance on threat versus non-threat conditions. Reliability was assessed using split-half and test-retest correlations of mean reaction times (RTs), accuracy and bias indices. Convergence between measures was also examined. Mean RTs showed substantial split-half and test-retest correlations. Bias score reliability coefficients were near zero and non-significant, suggesting poor reliability in children of this age. Additionally, associations between bias scores and anxiety were weak and inconsistent and performance between tasks showed little convergence. Bias scores from RT based paradigms in the current study lacked adequate psychometric properties for measuring individual differences in anxiety-related information-processing in children

Integrated Modelling of an Unmanned High-Altitude Solar-Powered Aircraft for Control Law Design Analysis

Solar-powered high-altitude unmanned platforms are highly optimized and integrated aircraft. In order to account for the complex, multi-physical interactions between their systems, we propose using integrated simulation models throughout the aircraft’s life cycle. Especially small teams with limited ressources should benefit from this approach. In this paper, we describe our approach to an integrated model of the Electric High-Altitude Solar-Powered Aircraft ELHASPA. It includes aspects of the environment, flight mechanics, energy system, and aeroelasticity. Model variants can be derived easily. The relevant parts of the model are described and the model’s application is demonstrated
MAGIC search for vhe γ-ray emission from ae aquarii in a multiwavelength context

Context. It has been claimed that the nova-like cataclysmic variable (CV) AE Aquarii (AE Aqr) is a very-high-energy (VHE, E >100 GeV) source both on observational and theoretical grounds. \ud
Aims. We search for VHE γ-ray emission from AE Aqr during different states of the source at several wavelengths to confirm or rule out previous claims of detection of γ-ray emission from this object.\ud
Methods. We report on observations of AE Aqr performed by MAGIC. The source was observed during 12 hours as part of a multiwavelength campaign carried out between May and June 2012 covering the optical, X-ray, and γ-ray ranges. Besides MAGIC, the other facilities involved were the KVA, Skinakas, and Vidojevica telescopes in the optical and Swift in X-rays. We calculated integral upper limits coincident with different states of the source in the optical. We computed upper limits to the pulsed emission limiting the signal region to 30% of the phaseogram and we also searched for pulsed emission at different frequencies applying the Rayleigh test \ud
Results. AE Aqr was not detected at VHE energies during the multiwavelength campaign. We establish integral upper limits at the 95% confidence level for the steady emission assuming the differential flux proportional to a power-law function dφ/dE ∝ E^(−Γ) , with a Crab-like photon spectral index of Γ=2.6. The upper limit above 200 GeV is 6.4×10^(−12) cm^(−2) s ^(−1) and above 1 TeV is 7.4×10^(−13) cm^(−2) s^( −1) . We obtained an upper limit for the pulsed emission of 2.6×10^(−12) cm^(−2) s^(−1) for energies above 200 GeV. Applying the Rayleigh test for pulsed emission at different frequencies we did not find any significant signal. Conclusions. Our results indicate that AE Aqr is not a VHE γ-ray emitter at the level of emission previously claimed. We have established the most constraining upper limits for the VHE γ-ray emission of AE Aqr
Competing particle–hole excitations in 30 Na: Constraining state-of-the-art effective interactions

The odd–odd nucleus 30 Na is studied via a one-proton, one-proton–one-neutron and one-neutron removal reaction using an intermediate-energy 31 Mg, 32 Mg and 31 Na radioactive ion beam, respectively. Combining high-resolution γ -ray spectroscopy with the selectivity of the three reaction mechanisms, we are able to distinguish multiple particle–hole configurations. Negative-parity states in 30 Na are observed for the first time, providing an important measure of the excitation of the 1p1h/3p3h configuration and hence the sd – pf shell gap. The extracted band structures and level energies serve as invaluable input for the theoretical refinement of the effective interactions used in this region
Hypernuclear production cross section in the reaction of 6 Li + 12 C at 2A GeV

Hypernuclear production cross sections have been deduced for the first time with induced reaction of heavy ion beam on fixed target and by means of the invariant mass method by the HypHI Collaboration exploiting the reaction of 6 Li + 12 C at 2A GeV or sNN=2.70 GeV . A production cross section of 3.9±1.4 μb for 3 Λ H and of 3.1±1.0 μb for 4 Λ H respectively in the projectile rapidity region was inferred as well as the total production cross section of the Λ hyperon was measured and found to be equal to 1.7±0.8 mb . A global fit based on a Bayesian approach was performed in order to include and propagate statistical and systematic uncertainties. Production ratios of 3 Λ H/ 4 Λ H, 3 Λ H/Λ and 4 Λ H/Λ were included in the inference procedure. The strangeness population factors S 3 and S 4 of 3 Λ H and 4 Λ H respectively were extracted. In addition, the multiplicities of the Λ hyperon, 3 Λ H, and 4 Λ H together with the rapidity and transversal momentum density distributions of the observed hypernuclei were extracted and reported
Thermodynamics of static dyonic AdS black holes in the ω -deformed Kaluza–Klein gauged supergravity theory

We study thermodynamical properties of static dyonic AdS black holes in four-dimensional ω -deformed Kaluza–Klein gauged supergravity theory, and find that the differential first law requires a modification via introducing a new pair of thermodynamical conjugate variables (X,Y) . To ensure such a modification, we then apply the quasi-local ADT formalism developed in Kim et al. (2013) [20] to calculate the quasi-local conserved charge and identify that the new pair is precisely the one previously introduced to modify the differential form of the first law
Entanglement entropy and duality in AdS 4

Small variations of the entanglement entropy δS and the expectation value of the modular Hamiltonian δE are computed holographically for circular entangling curves in the boundary of AdS4 , using gravitational perturbations with general boundary conditions in spherical coordinates. Agreement with the first law of thermodynamics, δS=δE , requires that the line element of the entangling curve remains constant. In this context, we also find a manifestation of electric–magnetic duality for the entanglement entropy and the corresponding modular Hamiltonian, following from the holographic energy–momentum/Cotton tensor duality
Jet (de)coherence in Pb–Pb collisions at the LHC

We study the modifications of jets created in heavy-ion collisions at LHC energies. The inherent hierarchy of scales governing the jet evolution allows to distinguish a leading jet structure, which interacts coherently with the medium as a single color charge, from softer sub-structures that will be sensitive to effects of color decoherence. We argue how this separation comes about and show that this picture is consistent with experimental data on reconstructed jets at the LHC, providing a quantitative description simultaneously of the jet nuclear modification factor, the missing energy in di-jet events and the modification of the fragmentation functions. In particular, we demonstrate that effects due to color decoherence are manifest in the excess of soft particles measured in fragmentation functions in Pb–Pb compared to proton–proton collisions
A large genome-wide association study of age-related macular degeneration highlights contributions of rare and common variants

This is the author accepted manuscript. The final version is available from Nature Publishing Group via http://dx.doi.org/10.1038/ng.3448Advanced age-related macular degeneration (AMD) is the leading cause of blindness in the elderly, with limited therapeutic options. Here we report on a study of >12 million variants, including 163,714 directly genotyped, mostly rare, protein-altering variants. Analyzing 16,144 patients and 17,832 controls, we identify 52 independently associated common and rare variants (P < 5 × 10−8) distributed across 34 loci. Although wet and dry AMD subtypes exhibit predominantly shared genetics, we identify the first genetic association signal specific to wet AMD, near MMP9 (difference P value = 4.1 × 10−10). Very rare coding variants (frequency <0.1%) in CFH, CFI and TIMP3 suggest causal roles for these genes, as does a splice variant in SLC16A8. Our results support the hypothesis that rare coding variants can pinpoint causal genes within known genetic loci and illustrate that applying the approach systematically to detect new loci requires extremely large sample sizes.We thank all participants of all the studies included for enabling this research by their participation in these studies.

Flexibility-based predictions of folding cores:characterization of the cyclophilin A - cyclosporin A complex

Determining the folding core of a protein yields information about its folding process and dynamics. The experimental procedures for identifying the amino acids that make up the folding core include hydrogen-deuterium exchange and F-value analysis and can be expensive and time consuming. Because of this, there is a desire to improve upon existing methods for determining protein folding cores theoretically. We have obtained HDX data for the complex of cyclophilin A with the immunosuppressant cyclosporin A. We compare these data, as well as literature values for uncomplexed cyclophilin A, to theoretical predictions using a combination of rigidity analysis and coarse-grained simulations of protein motion. We find that in this case, the most specific prediction of folding cores comes from a combined approach that models the rigidity of the protein using the First software suite and the dynamics of the protein using the FRODA tool
