A spectral line survey of Orion KL in the bands 486-492 and 541-577 GHz with the Odin satellite: II. Data analysis

Aims.We investigate the physical and chemical conditions in a typical star forming region, including an unbiased search for new molecules in a spectral region previously unobserved.Methods.Due to its proximity, the Orion KL region offers a unique laboratory of molecular astrophysics in a chemically rich, massive star forming region. Several ground-based spectral line surveys have been made, but due to the absorption by water and oxygen, the terrestrial atmosphere is completely opaque at frequencies around 487 and 557 GHz. To cover these frequencies we used the Odin satellite to perform a spectral line survey in the frequency ranges 486-492 GHz and 541-577 GHz, filling the gaps between previous spectral scans. Odin's high main beam efficiency, = 0.9, and observations performed outside the atmosphere make our intensity scale very well determined.Results.We observed 280 spectral lines from 38 molecules including isotopologues, and, in addition, 64 unidentified lines. A few U-lines have interesting frequency coincidences such as ND and the anion SH. The beam-averaged emission is dominated by CO, HO, SO, SO, CO and CHOH. Species with the largest number of lines are CHOH, (CHO, SO, CHOH, CHCN and NO. Six water lines are detected including the ground state rotational transition 1-1 of -HO, its isotopologues -HO and -HO, the Hot Core tracing -HO transition 6-7, and the 2-1 transition of HDO. Other lines of special interest are the 1-0 transition of NH and its isotopologue NH. Isotopologue abundance ratios of D/H, C/C, S/S, S/S, and O/O are estimated. The temperatures, column densities and abundances in the various subregions are estimated, and we find very high gas-phase abundances of HO, NH, SO, SO, NO, and CHOH. A comparison with the ice inventory of ISO sheds new light on the origin of the abundant gas-phase molecules.. © 2007 ESO.published_or_final_versio
Annular crustal accretion and reworking around the Yangtze nuclei during Neoproterozoic: a link to the initiation and termination of annular subduction of oceanic crust

This journal supplement has title: Awards Ceremony Speeches and Abstracts of the 19th Annual V.M. Goldschmidt ConferenceSubduction zones are primary sites of crustal growth and thus subsequent continental accretion on the Earth. In the modern cases, continental crustal growth along subduction zones generally takes place at one side of continental margins. However, the Yangtze Block provides us an annular style for the crustal growth and subsequent continental crust accretion during the late Mesoproterozoic to early Neoproterozoic. A series of lithologic associations at the time, including ophiolites, arc basalts, blueschist-facies metamorphic rocks, Stype and I-type granites, and high-K volcanic rocks, occur along the margins of the Yangtze Block. Hf isotopes in zircons from Neoproterozoic magmatic rocks around the Yangtze Block suggest growth of juvenile crust at ca. 0.95-1.3 Ga, indicating an annular subduction of oceanic crust around the Yangtze nuclei. The arc terranes may be accreted to the margins of the Yangtze Block during arc-continent collision of 0.95-0.86 Ga, with some newly-formed arc-derived rocks immediately remelted to generate syn-collisional volcanic rocks and granites. A subsequent giant reworking event of juvenile and old crustal materials took place at 0.85-0.80, which may be resulted from the upwelling of deep mantle and extension of lithosphere due to the termination of annular subduction. The mafic rocks of 0.85-0.80 Ga generally show geochemical features similar to the typical arc basalts, suggesting their sources may have been metasomatized during early subduction. The 0.95-0.86 Ga arc-continent collision and associated remelting has provided an efficient way not only for growth of continental nuclei during the late Precambrian, but also for chemical differentiation of crustal composition from basaltic to granitic ones.postprintThe 19th Annual Goldschmidt Conference, Davos, Switzerland, 21-26 June 2009.

Fluorescence ratiometric detection of ligand-induced receptor internalization using extracellular coiled-coil tag-probe labeling.

We report a new method for the detection of ligand-induced receptor internalization by fluorescence ratiometric imaging of pH in endosomes in combination with a recently developed posttranslational labeling system based on the formation of a heterodimeric coiled-coil structure. The N-terminus of the β2-adrenergic receptor expressed on the cell surface was doubly labeled with pH-sensitive fluorescein and pH-insensitive tetramethylrhodamine. A significant increase in the tetramethylrhodamine-to-fluorescein fluorescence intensity ratio was observed after incubation with agonists in a concentration-dependent manner. This simple and accurate method of detecting the agonistic activity of receptors will be useful for high-throughput screening of drug candidates
Campi Flegrei active seismic experiments waveforms compilation

A new experiment called SERAPIS (SEismic Reflection/Refraction
Acquisition Project for Imaging complex volcanic Structures) has been planned
and carried out, based on off-shore seismic energization and data acquisition on
land and on sea-bottom. The experiment was performed in September, 2001
during which the vessel NADIR of IFREMER (equipped with 12, 16-liters airgun)
produced more than 5000 air gun shots recorded at a sea-bottom seismograph
array of 72 OBS and 62 stations installed on-land. Active seismic refraction
DSS (Deep Seismic Soundings) acquired during the surveys conducted in
1980 and 1985 were recovered jointly with seismic data acquired in the Campi
Flegrei area in the framework of the MareVes97 (an experiment devoted to the
definition of the structure of the Somma-Vesuvio complex) offshore survey.
The data set acquired during the SERAPIS experiment has been successfully
used to infer 3D images of the volcanic structures of Campi Flegrei and
Neapolitan bay. Active seismic waveforms and related P-picks (more than
90000 data) from the SERAPIS experiment are also available in the project data

The acute inotropic effects of cardiac contractility modulation (CCM) are associated with action potential duration shortening and mediated by β1-adrenoceptor signalling.

Despite promising results in clinical trials conducted to date, little is known about how cardiac contractile modulation (CCM) mediated inotropic enhancement occurs and how CCM affects the electrophysiological characteristics of the heart. The aims of the present study were to 1) investigate how the stimulation parameters of the CCM signal and the location of stimulus delivery influence the contractile response, 2) characterise the effect of CCM on ventricular electrophysiology, and 3) investigate the potential physiological mechanisms underlying these acute inotropic and electrophysiological effects. Experiments were conducted in isolated rabbit hearts with simultaneous measurement of ventricular contractility and monophasic action potential duration (MAPD). Biphasic square wave pulses were applied to the left ventricle, timed to coincide with the absolute refractory period. CCM mediated responses were assessed over a range of signal amplitudes (2-30 mA), durations (2-15 ms) and delays from the activation of the locally recorded monophasic action potential (0-30 ms). Responses were assessed during perfusion with the β1-adrenoceptor antagonist metoprolol (1.8 μM) and HMR 1556 (500 nM), an inhibitor of the slow delayed rectifying potassium current. Norepinephrine content was collected and assessed by ELISA from samples of coronary effluent collected during CCM. CCM induced a significant increase in left ventricular pressure (LVP) in a manner dependent upon the amplitude and duration of the CCM signal but independent of the delay of the stimulus within the action potential plateau and was associated with an increase in norepinephrine in coronary effluent (Mean: 46±9 pg/ml). CCM promoted a shortening of MAPD-90% close to the site of stimulation (-19±3%) but had no effect on those recorded at distant sites (0±1%). The increase in LVP (4.7±1.8 vs. 0.7±0.9%, P<0.01) and shortening of local MAPD-90% (-15±3 vs. 1±1%, P<0.01) was abolished with metoprolol. Perfusion with HMR 1556 caused a significant inhibition of local MAPD shortening (-27±2 vs. -21±3 ms, P<0.05). CCM is associated with a shortening of ventricular MAPD in a manner dependent upon β-adrenoceptor stimulation resulting from catecholamine release, a finding which may be of clinical significance in regard to the development of malignant ventricular arrhythmias.

On the thermodynamics of periodic AdS black branes.

We consider asymptotically AdS black brane solutions that are dual to CFTs with periodic dependence on the spatial directions, arising from either a spontaneous or an explicit breaking of translational symmetry. We derive a simple expression for the variation of the free-energy with respect to changing the periods. This explains some observations, based on numerics, that have arisen in the explicit construction of thermodynamically preferred black holes in the case that the spatial directions are infinite in extent and the symmetry is spontaneously broken. It also leads to Smarr-type relations involving the boundary stress tensor
The mass-hierarchy and CP-violation discovery reach of the LBNO long-baseline neutrino experiment.\ud

The next generation neutrino observatory proposed by the LBNO collaboration will address fundamental questions in particle and astroparticle physics. The experiment consists of a far detector, in its first stage a 20 kt LAr double phase TPC and a magnetised iron calorimeter, situated at 2300 km from CERN and a near detector based on a highpressure argon gas TPC. The long baseline provides a unique opportunity to study neutrino flavour oscillations over their 1st and 2nd oscillation maxima exploring the L/E behaviour, and distinguishing effects arising from δ CP and matter.\ud
\ud
In this paper we have reevaluated the physics potential of this setup for determining the mass hierarchy (MH) and discovering CP-violation (CPV), using a conventional neutrino beam from the CERN SPS with a power of 750 kW. We use conservative assumptions on the knowledge of oscillation parameter priors and systematic uncertainties. The impact of each systematic error and the precision of oscillation prior is shown. We demonstrate that the first stage of LBNO can determine unambiguously the MH to > 5σ C.L. over the whole phase space. We show that the statistical treatment of the experiment is of very high importance, resulting in the conclusion that LBNO has ~ 100% probability to determine the MH in at most 4-5 years of running. Since the knowledge of MH is indispensable to extract δ CP from the data, the first LBNO phase can convincingly give evidence for CPV on the 3σ C.L. using today’s knowledge on oscillation parameters and realistic assumptions on the systematic uncertainties
Solvent mediated interactions close to fluid-fluid phase separation: microscopic treatment of bridging in a soft-core fluid

Copyright 2005 American Institute of Physics. This article may be downloaded for personal use only. Any other use requires prior permission of the author and the American Institute of Physics. The following article appeared in Journal of Chemical Physics, 2005, 122 (8), 084513 and may be found at: http://dx.doi.org/10.1063/1.1855878Using density functional theory we calculate the density profiles of a binary solvent adsorbed around a pair of big solute particles. All species interact via repulsive Gaussian potentials. The solvent exhibits fluid-fluid phase separation, and for thermodynamic states near to coexistence the big particles can be surrounded by a thick adsorbed "wetting" film of the coexisting solvent phase. On reducing the separation between the two big particles we find there can be a "bridging" transition as the wetting films join to form a fluid bridge. The effective (solvent mediated) potential between the two big particles becomes long ranged and strongly attractive in the bridged configuration. Within our mean-field treatment the bridging transition results in a discontinuity in the solvent mediated force. We demonstrate that accounting for the phenomenon of bridging requires the presence of a nonzero bridge function in the correlations between the solute particles when our model fluid is described within a full mixture theory based upon the Ornstein-Zernike equations
X-Ray Polarimetry with the Polarization Spectroscopic Telescope Array
  (PolSTAR)

This paper describes the Polarization Spectroscopic Telescope Array
(PolSTAR), a mission proposed to NASA's 2014 Small Explorer (SMEX) announcement
of opportunity. PolSTAR measures the linear polarization of 3-50 keV
(requirement; goal: 2.5-70 keV) X-rays probing the behavior of matter,
radiation and the very fabric of spacetime under the extreme conditions close
to the event horizons of black holes, as well as in and around magnetars and
neutron stars. The PolSTAR design is based on the technology developed for the
Nuclear Spectroscopic Telescope Array (NuSTAR) mission launched in June 2012.
In particular, it uses the same X-ray optics, extendable telescope boom,
optical bench, and CdZnTe detectors as NuSTAR. The mission has the sensitivity
to measure ~1% linear polarization fractions for X-ray sources with fluxes down
to ~5 mCrab. This paper describes the PolSTAR design as well as the science
drivers and the potential science return.Comment: (Astroparticle Physics in press, 34 pages, 23 figures, 6 tables
The mutable nature of particle-core excitations with spin in the
  one-valence-proton nucleus 133Sb

The gamma-ray decay of excited states of the one-valence-proton nucleus 133Sb
has been studied using cold-neutron induced fission of 235U and 241Pu targets,
during the EXILL campaign at the ILL reactor in Grenoble. By using a highly
efficient HPGe array, coincidences between gamma-rays prompt with the fission
event and those delayed up to several tens of microseconds were investigated,
allowing to observe, for the first time, high-spin excited states above the
16.6 micros isomer. Lifetimes analysis, performed by fast-timing techniques
with LaBr3(Ce) scintillators, reveals a difference of almost two orders of
magnitude in B(M1) strength for transitions between positive-parity medium-spin
yrast states. The data are interpreted by a newly developed microscopic model
which takes into account couplings between core excitations (both collective
and non-collective) of the doubly magic nucleus 132Sn and the valence proton,
using the Skyrme effective interaction in a consistent way. The results point
to a fast change in the nature of particle-core excitations with increasing
spin
Coulomb branches for rank 2 gauge groups in 3d N=4 gauge theories

The Coulomb branch of 3-dimensional N=4 gauge theories is the space of bare
and dressed BPS monopole operators. We utilise the conformal dimension to
define a fan which, upon intersection with the weight lattice of a GNO-dual
group, gives rise to a collection of semi-groups. It turns out that the unique
Hilbert bases of these semi-groups are a sufficient, finite set of monopole
operators which generate the entire chiral ring. Moreover, the knowledge of the
properties of the minimal generators is enough to compute the Hilbert series
explicitly. The techniques of this paper allow an efficient evaluation of the
Hilbert series for general rank gauge groups. As an application, we provide
various examples for all rank two gauge groups to demonstrate the novel
interpretation.Comment: v2: 98 pages, 30 figures, 34 tables, 1 appendix, matches JHEP versio
Pleasure: A forgotten dimension of physical activity in older age.

This is the author’s version of a work that was accepted for publication in Social Science and Medicine. Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published in Social Science and Medicine, Vol. 115(2014)and can be accessed via the DOI in this record.Pleasure is an under-researched and under theorized concept within health and health-related areas, particularly in relation to physical activity in older age. This gap is addressed here. The paper forms part of a larger qualitative project conducted between March 2011 and July 2013 within which fifty-one physically active older adults (age sixty to ninety-two years) were interviewed about their experiences of physical activity. Twenty-seven of these participants were also involved in a photo elicitation exercise whereby they responded to photographic images of themselves doing their activity. The paper reports in-depth on one of the themes - pleasure - that was initially identified through a rigorous categorical-content analysis of this data. An original typology of pleasure for physical activity in older age is developed, which details four significant ideal types of pleasure: sensual pleasure; documented pleasure; the pleasure of habitual action; and the pleasure of immersion. The implications of this typology for debates around embodiment, affect, and narratives of ageing are discussed in relation to health promotion and future research in this underserved area.Economic and Social Research Counci
First evidence for the two-body charmless baryonic decay

The results of a search for the rare two-body charmless baryonic decays TeX and TeX are reported. The analysis uses a data sample, corresponding to an integrated luminosity of 0.9 fb−1, of pp collision data collected by the LHCb experiment at a centre-of-mass energy of 7 TeV. An excess of TeX candidates with respect to background expectations is seen with a statistical significance of 3.3 standard deviations. This is the first evidence for a two-body charmless baryonic B 0 decay. No significant TeX signal is observed, leading to an improvement of three orders of magnitude over previous bounds. If the excess events are interpreted as signal, the 68.3% confidence level intervals on the branching fractions are $ TeX $ where the first uncertainty is statistical and the second is systematic
A search for flavour changing neutral currents in top-quark decays in pp collision data collected with the ATLAS detector at root s=7 TeV

A search for flavour changing neutral current (FCNC) processes in top-quark decays by the ATLAS Collaboration is presented. Data collected from pp collisions at the LHC at a centre-of-mass energy of root s = 7 TeV during 2011, corresponding to an integrated luminosity of 2.1 fb(-1), were used. A search was performed for top-quark pair-production events, with one top quark decaying through the t -> Zq FCNC (q = u, c) channel, and the other through the Standard Model dominant mode t -> Wb. Only the decays of the Z boson to charged leptons and leptonic W-boson decays were considered as signal. Consequently, the final-state topology is characterised by the presence of three isolated charged leptons, at least two jets and missing transverse momentum from the undetected neutrino. No evidence for an FCNC signal was found. An upper limit on the t -> Zq branching ratio of BR(t -> Zq) < 0.73% is set at the 95% confidence level
On the Ginzburg–Landau Functional in the Surface Superconductivity Regime

Revision of the version published in Communications in Mathematical Physics 332  (3), 1297-1343 (2014).  Minor mistakes corrected and Theorem 2.4 reformulated accordingly.We present new estimates on the two-dimensional Ginzburg-Landau energy of a type-II superconductor in an applied magnetic field varying between the second and third critical fields. In this regime, superconductivity is restricted to a thin layer along the boundary of the sample. We provide new energy lower bounds, proving that the Ginzburg-Landau energy is determined to leading order by the minimization of a simplified 1D functional in the direction perpendicular to the boundary. Estimates relating the density of the Ginzburg-Landau order parameter to that of the 1D problem follow. In the particular case of a disc sample, a refinement of our method leads to a pointwise estimate on the Ginzburg-Landau order parameter, thereby proving a strong form of uniformity of the surface superconductivity layer, related to a conjecture by Xing-Bin Pan
Maritime Shipping and Emissions: A three-layered, damage based approach

-Policy emphasis in ship design must be shifted away from global and idealized towards regional based and realistic vessel operating conditions. The present approach to reducing shipping emissions through technical standards tends to neglect how damages and abatement opportunities vary according to location and operational conditions. Since environmental policy originates in damages relating to ecosystems and jurisdictions, a three-layered approach to vessel emissions is intuitive and practical. Here, we suggest associating damages and policies with ports, coastal areas possibly defined as Emission Control Areas (ECA) as in in North Sea and the Baltic, and open seas globally. This approach offers important practical opportunities: in ports, clean fuels or even electrification is possible; in ECAs, cleaner fuels and penalties for damaging fuels are important, but so is vessel handling, such as speeds and utilization. Globally we argue that it may be desirable to allow burning very dirty fuels at high seas, due to the cost advantages, the climate cooling benefits, and the limited ecosystem impacts. We quantify the benefits and cost savings from reforming current IMO and other approaches towards environmental management with a three-layered approach, and argue it is feasible and worth considering
