The 0.1 < z < 1.65 evolution of the bright end of the [O II] luminosity function

Astronomy and Astrophysics 575 (2015): A40 reproduced with permission from Astronomy & Astrophysics, © ESOWe present the [OII] (λλ3729,3726) luminosity function measured in the redshift range 0.1 <z< 1.65 with unprecedented depth and accuracy. Our measurements are based on medium resolution flux-calibrated spectra of emission line galaxies with the visual and near UV FOcal Reducer and low dispersion Spectrograph (FORS2) for the Very Large Telescope (VLT) of the European Southern Observatory (ESO) and with the SDSS-III/BOSS spectrograph. The FORS2 spectra and the corresponding catalog containing redshifts and line fluxes are released along with this paper. In this work we use a novel method to combine these surveys with GAMA, zCOSMOS, and VVDS, which have different target selection, producing a consistent weighting scheme to derive the [OII] luminosity function. The[OII] luminosity function is in good agreement with previous independent estimates. The comparison with two state-of-the-art semi-analytical models is good, which is encouraging for the production of mock catalogs of [OII] flux limited surveys. We observe the bright end evolution over 8.5 Gyr: we measure the decrease of logL∗ from 42.4 erg/s at redshift 1.44 to 41.2 at redshift 0.165 and we find that the faint end slope flattens when redshift decreases. This measurement confirms the feasibility of the target selection of future baryonic acoustic oscillation surveys aiming at observing [OII] flux limited samplesJ.C. acknowledges financial support from MINECO (Spain) under project number AYA2012-31101.

Global Twisting Motion of Single Molecular KcsA Potassium Channel upon Gating.

Ion channels are signal transduction molecules that switch ion permeation pathways on and off (gating). Crystal structures of several kinds of potassium channels have revealed open and closed conformations, which provide static pictures of gating status. Here we studied KcsA potassium channels undergoing conformational changes at the single-molecule level. A KcsA channel with a gold nanocrystal attached was irradiated by white X-rays and motions of the diffraction spot from the nanocrystal were tracked in real time. Upon gating, the KcsA channels twisted around the axis of the pore. These conformational changes were prevented by an open-channel blocker, tetrabuthylammonium. Random clockwise and counterclockwise twisting in the range of several tens of degrees originated in the transmembrane domain and was transmitted to the cytoplasmic domain. This coupling suggests a mechanical interplay between the transmembrane and cytoplasmic domains
Measurement of the W(+/-)Z production cross section and limits on anomalous triple gauge couplings in proton-proton collisions at root s=7 TeV with the ATLAS detector

This Letter presents a measurement of W(+/-)Z production in 1.02 fb(-1) of pp collision data at root s = 7 TeV collected by the ATLAS experiment in 2011. Doubly leptonic decay events are selected with electrons, muons and missing transverse momentum in the final state. In total 71 candidates are observed, with a background expectation of 12.1 +/- 1.4(stat.)(-2.0)(+4.1)(syst.) events. The total cross section for W(+/-)Z production for Z/gamma* masses within the range 66 GeV to 116 GeV is determined to be sigma(tot)(WZ) = 20.5(-2.8)(+3.1)(stat.)(-1.3)(+1.4)(syst)(-0.8)(+0.9)(lumi.) pb, which is consistent with the Standard Model expectation of 17.3(0.8)(+1.3) pb. Limits on anomalous triple gauge boson couplings are extracted
Cardiovascular disease in dementia

The objective of this thesis was to characterize the burden of cardiovascular diseases in
patients with dementia, their treatment and association with survival. Further, we aimed to
explore whether cardiac structure in young adults can affect the aging brain. We performed 5
observational cohort studies, based on patients registered in the Swedish Dementia Registry
(Papers I-IV) and participants in a population-based study Coronary Artery Risk
Development in Young Adults (Paper V).



The results can be summarized as follows:



(I) Seventy per cent of patients with dementia are prescribed cardiovascular drugs.
Their use is highest in patients with vascular dementia and lowest in patients with
Parkinson´s disease dementia.



(II) Patients with heart failure and dementia constitute an old and under-diagnosed
population. Heart failure with preserved ejection fraction is the most common
type of heart failure and vascular dementia the most frequent dementia disorder.



(III) The most common chronic cardiovascular disease in patients with dementia is
ischemic heart disease (23% of patients are affected), followed by cerebrovascular
diseases (20% of patients) and atrial fibrillation (19% of patients). The occurrence
and prognostic significant of chronic cardiovascular diseases differs in specific
dementia disorders.



(IV) Twenty one per cent of patients with dementia are managed invasively for acute
myocardial infarction. The use of invasive procedures is associated with lower
age and higher cognitive status. This study suggests that the invasive management
of myocardial infarction has a benefit for survival of patients with dementia.



(V) Higher left atrial volume in young adulthood is associated with lower white
matter integrity in mid-life. This study suggests that improvement of cardiac
function in young adults may benefit the aging brain
Observation of $\Upsilon(\mathrm{1S})$ pair production in proton-proton collisions at $\sqrt{s}$ = 8 TeV

Pair production of $\Upsilon(\mathrm{1S})$ mesons is observed at the LHC in proton-proton collisions at $ \sqrt{s} = $ 8 TeV by the CMS experiment in a data sample corresponding to an integrated luminosity of 20.7 fb$^{-1}$. Both $\Upsilon(\mathrm{1S})$ candidates are fully reconstructed via their decays to $\mu^{+}\mu^{- } $. The fiducial acceptance region is defined by an absolute $\Upsilon(\mathrm{1S})$ rapidity smaller than 2.0. The fiducial cross section for the production of $\Upsilon(\mathrm{1S})$ pairs, assuming that both mesons decay isotropically, is measured to be 68.8 $\pm$ 12.7 (stat) $\pm$ 7.4 (syst) $\pm$ 2.8 ($\mathcal{B}$) pb, where the third uncertainty comes from the uncertainty in the branching fraction of $\Upsilon(\mathrm{1S})$ decays to $\mu^{+}\mu^{-}$. Assuming instead that the $\Upsilon(\mathrm{1S})$ mesons are produced with different polarizations leads to variations in the measured cross section in the range from $-38\%$ to $+36\%$
Search for a very light NMSSM Higgs boson produced in decays of the 125 GeV scalar boson and decaying into tau leptons in pp collisions at sqrt(s) = 8 TeV

A search for a very light Higgs boson decaying into a pair of tau leptons is presented within the framework of the next- to-minimal supersymmetric standard model. This search is based on a data set corresponding to an integrated luminosity of 19.7 inverse femtobarns of proton-proton collisions collected by the CMS experiment at a centre-of- mass energy of 8 TeV. The signal is defined by the production of either of the two lightest scalars, h[1] or h[2], via gluon-gluon fusion and subsequent decay into a pair of the lightest Higgs bosons, a[1] or h[1]. The h[1] or h[2] boson is identified with the observed state at a mass of 125 GeV. The analysis searches for decays of the a[1] (h[1]) states into pairs of tau leptons and covers a mass range for the a[1] (h[1]) boson of 4 to 8 GeV. The search reveals no significant excess in data above standard model background expectations, and an upper limit is set on the signal production cross section times branching fraction as a function of the a[1] (h[1]) boson mass. The 95% confidence level limit ranges from 4.5 pb at m(a[1]) (m(h[1])) = 8 GeV to 10.3 pb at m(a[1]) (m(h[1])) = 5 GeV
Regularity of the Surface Density of States

AbstractWe prove that the integrated surface density of states of continuous or discrete Anderson-type random Schrödinger operators is a measurable locally integrable function rather than a signed measure or a distribution. This generalizes our recent results on the existence of the integrated surface density of states in the continuous case and those of A. Chahrour in the discrete case. The proof uses the new Lp-bound on the spectral shift function recently obtained by Combes, Hislop, and Nakamura. Also we provide a simple proof of their result on the Hölder continuity of the integrated density of bulk states
Secreted Ephrin Receptor A7 Promotes Somatic Cell Reprogramming by Inducing ERK Activity Reduction

SummaryThe role of secreted molecules in cellular reprogramming has been poorly understood. Here we identify a truncated form of ephrin receptor A7 (EPHA7) as a key regulator of reprogramming. Truncated EPHA7 is prominently upregulated and secreted during reprogramming. EPHA7 expression is directly regulated by OCT3/4. EphA7 knockdown results in marked reduction of reprogramming efficiency, and the addition of truncated EPHA7 is able to restore it. ERK activity is markedly reduced during reprogramming, and the secreted, truncated EPHA7 is responsible for ERK activity reduction. Remarkably, treatment of EphA7-knockdown MEFs with the ERK pathway inhibitor restores reprogramming efficiency. Analyses show that truncated EPHA7-induced ERK activity reduction plays an important role in the middle phase of reprogramming. Thus, our findings uncover the importance of secreted EPHA7-induced ERK activity reduction in reprogramming
Neutron-induced Fission Cross Section of240,242Pu

A sensitivity analysis for the new generation of fast reactors [Salvatores (2008)] has shown the importance\ud
of improved cross section data for several actinides. Among them, the240,242Pu(n,f) cross sections require an\ud
accuracy improvement to 1-3% and 3-5%, respectively, from the current level of 6% and 20%. At the Van de Graaff\ud
facility of the Institute for Reference Materials and Measurements (JRC-IRMM) the fission cross section of the two\ud
isotopes was measured relative to two secondary standard reactions,237Np(n,f) and238U(n,f), using a twin Frisch-grid\ud
ionization chamber. The secondary standard reactions were benchmarked through measurements against the primary\ud
standard reaction235U(n,f) in the same geometry. Sample masses were determined by means of low-geometry alpha\ud
counting or/and a 2p Frisch-grid ionization chamber, with an uncertainty lower than 2%. The neutron flux and the\ud
impact of scattering from material between source and target was examined, the largest effect having been found\ud
in cross section ratio measurements between a fissile and a fertile isotope. Our240,242Pu(n,f) cross sections are in\ud
agreement with previous experimental results and slightly lower than present evaluations. In case of the242Pu(n,f)\ud
reaction no evidence for a resonance at En=1.1 MeV was found.Postprint (published version
Anti-de-Sitter regular electric multipoles: Towards Einstein–Maxwell-AdS solitons

AbstractWe discuss electrostatics in Anti-de-Sitter (AdS) spacetime, in global coordinates. We observe that the multipolar expansion has two crucial differences to that in Minkowski spacetime. First, there are everywhere regular solutions, with finite energy, for every multipole moment except for the monopole. Second, all multipole moments decay with the same inverse power of the areal radius, 1/r, as spatial infinity is approached. The first observation suggests there may be regular, self-gravitating, Einstein–Maxwell solitons in AdS spacetime. The second observation, renders a Lichnerowicz-type no-soliton theorem inapplicable. Consequently, we suggest Einstein–Maxwell solitons exist in AdS, and we support this claim by computing the first order metric perturbations sourced by test electric field multipoles, which are obtained analytically in closed form
The kappa in E791 data for D→Kππ

AbstractA combined fit is made to E791 data on D→Kππ, LASS data on Kπ elastic scattering, and BES II data on J/Ψ→K∗(890)Kπ. In all cases, the Kπ S-wave is fitted well with a κ pole and K0(1430); the κ requires an s-dependent width with an Adler zero near threshold. The pole position of the κ is at M=(750−55+30)−i(342±60) MeV. The E791 Collaboration fitted their data using a form factor for the production process D→κπ. It is shown that this form factor is not needed. The data require point-like production with an RMS radius <0.38 fm with 95% confidence
Bethe–Salpeter bound-state structure in Minkowski space

AbstractThe quantitative investigation of the scalar Bethe–Salpeter equation in Minkowski space, within the ladder-approximation framework, is extended to include the excited states. This study has been carried out for an interacting system composed by two massive bosons exchanging a massive scalar, by adopting (i) the Nakanishi integral representation of the Bethe–Salpeter amplitude, and (ii) the formally exact projection onto the null plane. Our analysis, on one hand, confirms the reliability of the method already applied to the ground state and, on the other one, extends the investigation from the valence distribution in momentum space to the corresponding quantity in the impact-parameter space, pointing out some relevant features, like (i) the equivalence between Minkowski and Euclidean transverse-momentum amplitudes, and (ii) the leading exponential fall-off of the valence wave function in the impact-parameter space
Spin(7)-manifolds and symmetric Yang–Mills instantons

AbstractIn this Letter we establish a relationship between symmetric SU(2) Yang–Mills instantons and metrics with Spin(7) holonomy. Our method is based on a slight extension of that of Bryant and Salamon developed to construct explicit manifolds with special holonomies in 1989.More precisely, we prove that making use of symmetric SU(2) Yang–Mills instantons on Riemannian spin-manifolds, we can construct metrics on the chiral spinor bundle whose holonomy is within Spin(7). Moreover, if the resulting space is connected, simply connected and complete, the holonomy coincides with Spin(7).The basic explicit example is the metric constructed on the chiral spinor bundle of the round four-sphere by using a generic SU(2)-instanton of unit action; hence it is a five-parameter deformation of the Bryant–Salamon example, also found by Gibbons, Page and Pope
SU(2) Dirac–Yang–Mills quantum mechanics of spatially constant quark and gluon fields

AbstractThe quantum mechanics of spatially constant SU(2) Yang–Mills- and Dirac-fields minimally coupled to each other is investigated as the strong coupling limit of 2-color-QCD. Using a canonical transformation of the quark and gluon fields, which Abelianises the Gauss law constraints to be implemented, the corresponding unconstrained Hamiltonian and total angular momentum are derived. In the same way as this reduces the colored spin-1 gluons to unconstrained colorless spin-0 and spin-2 gluons, it reduces the colored spin-12 quarks to unconstrained colorless spin-0 and spin-1 quarks. These however continue to satisfy anti-commutation relations and hence the Pauli-exclusion principle. The obtained unconstrained Hamiltonian is then rewritten into a form, which separates the rotational from the scalar degrees of freedom. In this form the low-energy spectrum can be obtained with high accuracy. As an illustrative example, the spin-0 energy-spectrum of the quark–gluon system is calculated for massless quarks of one flavor. It is found, that only for the case of 4 reduced quarks (half-filling) satisfying the boundary condition of particle–antiparticle C-symmetry, states with energy lower than for the pure-gluon case are obtained. These are the ground state, with an energy about 20% lower than for the pure-gluon case and the formation of a quark condensate, and the sigma–antisigma excitation with an energy about a fifth of that of the first glueball excitation
Nickel nanocatalyst exsolution from (La,Sr) (Cr,M,Ni)O3 (MMn,Fe) perovskites for the fuel oxidation layer of Oxygen Transport Membranes

AbstractLa0.75Sr0.25Cr0.5Mn0.5O3 (LSCM) and La0.75Sr0.25Cr0.5Fe0.5O3 (LSCF) perovskites with partial substitution of the B-site by 5mol% of Ni were synthesised and characterised for the fuel oxidation layer of Oxygen Transport Membranes (OTMs). X-ray diffraction showed that single phase compounds were obtained at 1300°C. LSCM exhibits a rhombohedral structure and LSCF an orthorhombic structure. Both materials retain their structures, after doping the B site with Ni, with small changes on the unit cell parameters. Thermal analysis under reducing conditions was used to investigate the reducibility of these perovskites up to 900°C, which appears to be enhanced by doping with Ni. The formation of Ni nanoparticles (30–50nm) on the LSCMNi and LSCFNi grains was observed by scanning electron microscopy, after reducing the samples in 5% H2/Ar at 900°C, indicating possible enhanced catalytic activity and potential benefits for the development of the OTMs. DC conductivity measurements conducted under a redox cycle, indicate that LSCFNi presents a better redox stability than LSCMNi
Justice and conservation: The need to incorporate recognition

AbstractIn light of the Aichi target to manage protected areas equitably by 2020, we ask how the conservation sector should be incorporating concerns for social justice. We focus in particular on ‘recognition’, because it is the least well understood aspect of environmental justice, and yet highly relevant to conservation because of its concern with respect for local knowledge and cultures. In order to explore the meaning of recognition in the conservation context, we take four main steps. First, we identify four components of recognition to serve as our analytical framework: subjects of justice, the harms that constitute injustice, the mechanisms that produce injustices, and the responses to alleviate these. Secondly, we apply this framework to explore four traditions of thinking about recognition: Hegelian intersubjectivity, critical theory, southern decolonial theory, and the capabilities approach. Thirdly, we provide three case studies of conservation conflicts highlighting how different theoretical perspectives are illustrated in the claims and practices of real world conservation struggles. Fourthly, we finish the paper by drawing out some key differences between traditions of thinking, but also important areas of convergence. The convergences provide a basis for concluding that conservation should look beyond a distributive model of justice to incorporate concerns for social recognition, including careful attention to ways to pursue equality of status for local conservation stakeholders. This will require reflection on working practices and looking at forms of intercultural engagement that, for example, respect alternative ways of relating to nature and biodiversity
Relative Contribution of Feedforward Excitatory Connections to Expression of Ocular Dominance Plasticity in Layer 4 of Visual Cortex

SummaryBrief monocular deprivation (MD) shifts ocular dominance (OD) in primary visual cortex by causing depression of responses to the deprived eye. Here we address the extent to which the shift is expressed by a modification of excitatory synaptic transmission. An OD shift was first induced with 3 days of MD, and then the influences of intracortical polysynaptic inhibitory and excitatory synapses were pharmacologically removed, leaving only “feedforward” thalamocortical synaptic currents. The results show that the rapid OD shift following MD is strongly expressed at the level of thalamocortical synaptic transmission
Efficient Patterns for Model Checking Partial State Spaces in CTL ∩ LTL

AbstractCompositional model checks of partial Kripke structures are efficient but incomplete as they may fail to recognize that all implementations satisfy the checked property. But if a property holds for such checks, it will hold in all implementations. Such checks are therefore under-approximations. In this paper we determine for which popular specification patterns, documented at a communityled pattern repository, this under-approximation is precise in that the converse relationship holds as well for all model checks. We find that many such patterns are indeed precise. Those that aren't lose precision because of a sole propositional atom in mixed polarity. Hence we can compute, with linear blowup only, a semantic minimization in the same temporal logic whose efficient check renders the precise result for the original imprecise pattern. Thus precision can be secured for all patterns at low cost
Virtual coupling potential for elastic scattering of 10,11Be on proton and carbon targets

AbstractThe 10,11Be(p, p) and (12C, 12C) reactions were analyzed to determine the influence of the weak binding energies of exotic nuclei on their interaction potential. The elastic cross sections were measured at GANIL in inverse kinematics using radioactive 10,11Be beams produced at energies of 39.1A and 38.4A MeV. The elastic proton scattering data were analyzed within the framework of the microscopic Jeukenne–Lejeune–Mahaux (JLM) nucleon–nucleus potential. The angular distributions are found to be best reproduced by reducing the real part of the microscopic optical potential, as a consequence of the coupling to the continuum. These effects modify deeply the elastic potential. Including the Virtual Coupling Potential (VCP), we show the ability of the general optical potentials to reproduce the data for scattering of unstable nuclei, using realistic densities. Finally, the concepts needed to develop a more general and microscopic approach of the VCP are discussed
Scaling of hadron masses and widths in thermal models for ultrarelativistic heavy-ion collisions

AbstractBy means of a simple rescaling, modifications of hadron masses and widths are incorporated into the thermal analysis of particle ratios in ultrarelativistic heavy-ion collisions. We find that moderate, up to 20%, changes of hadron masses do not spoil the quality of the fits, which remain as good as those obtained without modifications. Larger changes are not likely. The fits with the modified masses yield modified values of the optimal temperature and baryon chemical potential. In particular, with decreasing masses of all hadrons (except for pseudo-Goldstone bosons) the fitted values of the temperature and the baryon chemical potential are lowered, with the change approximately proportional to the scaling of masses. In addition, we find that the broadening of the hadron widths by less than a factor of two practically does not affect the fits
