A topological analysis of void spaces in tungstate frameworks:assessing storage properties for the environmentally important guest molecules and ions: CO2, UO2, PuO2, U, Pu, Sr2+, Cs+, CH4, and H2

The identification of inorganic materials, which are able to encapsulate environmentally important small molecules or ions via host-guest interactions, is crucial for the design and development of next-generation energy sources and for storing environmental waste. Especially sought after are molecular sponges with the ability to incorporate CO2, gas pollutants, or nuclear waste materials such as UO2 and PuO2 oxides or U, Pu, Sr2+ or Cs+ ions. Porous framework structures promise very attractive prospects for applications in environmental technologies, if they are able to incorporate CH4 for biogas energy applications, or to store H2, which is important for fuel cells e.g. in the automotive industry. All of these applications should benefit from the host being resistant to extreme conditions such as heat, nuclear radiation, rapid gas expansion, or wear and tear from heavy gas cycling. As inorganic tungstates are well known for their thermal stability, and their rigid open-framework networks, the potential of Na2O-Al2O3-WO3 and Na2O-WO3 phases for such applications was evaluated. To this end, all known experimentally-determined crystal structures with the stoichiometric formula MaM’bWcOd (M = any element) are surveyed together with all corresponding theoretically calculated NaaAlbWcOd and NaxWyOz structures that are statistically likely to form. Network descriptors that categorize these host structures are used to reveal topological patterns in the hosts, including the nature of porous cages which are able to accommodate a certain type of guest; this leads to the classification of preferential structure types for a given environmental storage application. Crystal structures of two new tungstates NaAlW2O8 (1) and NaAlW3O11 (2) and one updated structure determination of Na2W2O7 (3) are also presented from in-house X-ray diffraction studies, and their potential merits for environmental applications are assessed against those of this larger data-sourced survey. Overall, results show that tungstate structures with three-nodal topologies are most frequently able to accommodate CH4 or H2, while CO2 appears to be captured by a wide range of nodal structure types. The computationally generated host structures appear systematically smaller than the experimentally determined structures. For the structures of 1 and 2, potential applications in nuclear waste storage seem feasible
Ionization rates in the heliosheath and in astrosheaths: spatial dependence and dynamical relevance

Context. In the heliosphere, especially in the inner heliosheath, mass-, momentum-, and energy-loading induced by the ionization of
neutral interstellar species plays an important, but for some species, especially helium, an underestimated role.
Aims. We discuss the implementation of charge exchange and electron impact processes for interstellar neutral hydrogen and helium
and their implications for the subsequent modeling. We especially emphasize the importance of electron impact and a more sophisticated
numerical treatment of the charge exchange reactions. Moreover, we discuss the nonresonant charge exchange effects.
Methods. We discuss rate coeffcients and revise the influence of the cross-sections in the (magneto-)hydrodynamic equations for
different reactions and also their representation in the collision integrals.
Results. Electron impact is in some regions of the heliosphere, particularly in the heliotail, more effective than charge exchange, and
the ionization of neutral interstellar helium contributes about 40% to the mass- and momentum-loading in the heliosheath. The charge
exchange cross-sections need to be modeled with higher accuracy, especially in view of the latest developments made in describing
them.
Conclusions. The ionization of helium and the electron impact ionization of hydrogen need to be taken into account in modeling the
heliosheath and, in general, astrosheaths. Moreover, the charge exchange cross-sections need to be handled in a more sophisticated
way, either by developing better analytic approximations or by numerically solving the collision integralsK.S. and H.F. are grateful to the Deutsche Forschungsgemeinschaft,

Genetic variation near IRS1 associates with reduced adiposity and an impaired metabolic profile.

To access publisher full text version of this article. Please click on the hyperlink in Additional Links field.Genome-wide association studies have identified 32 loci influencing body mass index, but this measure does not distinguish lean from fat mass. To identify adiposity loci, we meta-analyzed associations between ∼2.5 million SNPs and body fat percentage from 36,626 individuals and followed up the 14 most significant (P < 10(-6)) independent loci in 39,576 individuals. We confirmed a previously established adiposity locus in FTO (P = 3 × 10(-26)) and identified two new loci associated with body fat percentage, one near IRS1 (P = 4 × 10(-11)) and one near SPRY2 (P = 3 × 10(-8)). Both loci contain genes with potential links to adipocyte physiology. Notably, the body-fat-decreasing allele near IRS1 is associated with decreased IRS1 expression and with an impaired metabolic profile, including an increased visceral to subcutaneous fat ratio, insulin resistance, dyslipidemia, risk of diabetes and coronary artery disease and decreased adiponectin levels. Our findings provide new insights into adiposity and insulin resistance
How doctors record breaking bad news in ovarian cancer.

Revealing the diagnosis of cancer to patients is a key event in their cancer journey. At present, there are no minimal legal recommendations for documenting such consultations. We reviewed the Hospital records of 359 patients with epithelial ovarian cancer in the Mersey Area between 1992 and 1994. We identified the following factors: age, hospital, postcode, surgeon, stage of disease and survival. These were compared to information recorded at the time of the interview such as person present, descriptive words used, prognosis, further treatment and emotional response. In 11.6%, there was no information recorded in the notes. The diagnosis was recorded in 304 (94.7%), prognosis in 66 (20.6%) and collusion with relatives in 33 (10.3%). A total of 42 separate words/phrases were identified relating to diagnosis; cancer was recorded in 60 (19.6%). Collusion was three times as common in the patients over 65 years (17.9 vs 5.7%, P=0.001). There was a reduction in the number of diagnostic words recorded in the patients over 65 years (90.3 vs 98.3%, P=0.002) and by type of surgeon (P=0.001). Information was often poorly recorded in the notes. We have shown that the quality of information varies according to patient age, surgeon and specialty.1757
CUTLASS observations of a high-m ULF wave and its consequences for the DOPE HF Doppler sounder

The CUTLASS (Co-operative UK Twin Located Auroral Sounding System) Finland HF radar, whilst operating in a high spatial and temporal resolution mode, has measured the ionospheric signature of a naturally occurring ULF wave in scatter artificially generated by the Tromsù Heater. The wave had a period of 100 s and exhibited curved phase fronts across the heated volume (about 180 km along a single radar beam). Spatial information provided by CUTLASS has enabled an m-number for the wave of about 38 to be determined. This high-m wave was not detected by the IMAGE (International Monitor for Auroral Geomagnetic Efects) network of ground magnetometers, as expected for a wave of a small spatial scale size. These observations over the first independent confirmation of the existence of the ground uncorrelated ULF wave signatures previously reported in measurements recorded from an HF Doppler sounder located in the vicinity of Tromsö. These results both demonstrate a new capability for geophysical exploration from the combined CUTLASS-EISCAT ionospheric Heater experiment, and provide a verification of the HF Doppler technique for the investigation of small scale ULF waves.4219
On the connection between probability boxes and possibility measures.

We explore the relationship between possibility measures (supremum preserving normed measures) and p-boxes (pairs of cumulative distribution functions) on totally preordered spaces, extending earlier work in this direction by De Cooman and Aeyels, among others. We start by demonstrating that only those p-boxes who have 0-1-valued lower or upper cumulative distribution function can be possibility measures, and we derive expressions for their natural extension in this case. Next, we establish necessary and sufficient conditions for a p-box to be a possibility measure. Finally, we show that almost every possibility measure can be modelled by a p-box, simply by ordering elements by increasing possibility. Whence, any techniques for p-boxes can be readily applied to possibility measures. We demonstrate this by deriving joint possibility measures from marginals, under varying assumptions of independence, using a technique known for p-boxes. Doing so, we arrive at a new rule of combination for possibility measures, for the independent case
From d logs to dilogs ; the super Yang-Mills MHV amplitude revisited.

Recently, loop integrands for certain Yang-Mills scattering amplitudes and correlation functions have been shown to be systematically expressible in dlog form, raising the possibility that these loop integrals can be performed directly without Feynman parameters. We do so here to give a new description of the planar 1-loop MHV amplitude in N = 4 super Yang-Mills theory. We explicitly incorporate the standard Feynman i epsilon prescription into the integrands. We find that the generic MHV diagram contributing to the 1-loop MHV amplitude, known as Kermit, is dual conformal invariant up to the choice of reference twistor explicit in our axial gauge (the generic MHV diagram was already known to be finite). The new formulae for the amplitude are nontrivially related to previous ones in the literature. The divergent diagrams are evaluated using mass regularization. Our techniques extend directly to higher loop diagrams, and we illustrate this by sketching the evaluation of a non-trivial 2-loop example. We expect this to lead to a simple and efficient method for computing amplitudes and correlation functions with less supersymmetry and without the assumption of planarity
The detection of wind turbine shaft misalignment using temperature monitoring.

Temperature is a parameter increasingly monitored in wind turbine systems. This paper details a potential temperature monitoring technique for use on shaft couplings. Such condition monitoring methods aid fault detection in other areas of wind turbines. However, application to shaft couplings has not previously been widely researched.\ud
\ud
A novel temperature measurement technique is outlined, using an infra-red thermometer which can be applied to online condition monitoring. The method was validated and investigated through real time shaft alignment tests. Different modes of misalignment including offset and angular were investigated. This allowed analysis of the relationship between a change in shaft alignment and a change in temperature. The rate of change was found to be a factor of condition through exploring changes in ambient and operating temperatures. The test rig allowed quantification on a small scale and potential causes and effects of temperature changes are discusse
Search for a low-mass pseudoscalar Higgs boson produced in association
  with a b b-bar pair in pp collisions at sqrt(s) = 8 TeV

A search is reported for a light pseudoscalar Higgs boson decaying to a pair
of tau leptons, produced in association with a b b-bar pair, in the context of
two-Higgs-doublet models. The results are based on pp collision data at a
centre-of-mass energy of 8 TeV collected by the CMS experiment at the LHC and
corresponding to an integrated luminosity of 19.7 inverse femtobarns.
Pseudoscalar boson masses between 25 and 80 GeV are probed. No evidence for a
pseudoscalar boson is found and upper limits are set on the production cross
section times branching fraction to tau pairs between 7 and 39 pb at the 95%
confidence level. This excludes pseudoscalar A bosons with masses between 25
and 80 GeV, with standard model-like Higgs boson negative couplings to
down-type fermions, produced in association with b b-bar pairs, in Type-II,
two-Higgs-doublet models.Comment: Replaced with published version. Put in journal reference and DOI.

Observation of b$_2$ symmetry vibrational levels of the SO$_2$
  $\tilde{\mbox{C}}$ $^1$B$_2$ state: Vibrational level staggering, Coriolis
  interactions, and rotation-vibration constants

The $\mathrm{\tilde{C}}$ $^1$B$_2$ state of SO$_2$ has a double-minimum
potential in the antisymmetric stretch coordinate, such that the minimum energy
geometry has nonequivalent SO bond lengths. However, low-lying levels with odd
quanta of antisymmetric stretch (b$_2$ vibrational symmetry) have not
previously been observed because transitions into these levels from the
zero-point level of the $\mathrm{\tilde{X}}$ state are vibronically forbidden.
We use IR-UV double resonance to observe the b$_2$ vibrational levels of the
$\mathrm{\tilde{C}}$ state below 1600 cm$^{-1}$ of vibrational excitation. This
enables a direct characterization of the vibrational level staggering that
results from the double-minimum potential. In addition, it allows us to
deperturb the strong $c$-axis Coriolis interactions between levels of a$_1$ and
b$_2$ vibrational symmetry, and to determine accurately the vibrational
dependence of the rotational constants in the distorted $\mathrm{\tilde{C}}$
electronic state

                  157043pub.pdf (publisher's version ) (Closed access)In spite of the differences in human resource management (HRM) practices between the non-profit health care sector and business life, the majority of health care sector research appears to be based on the HRM (for human resources management) blueprint for business life staff policy and practice. This study is aimed to better understand the impact of workplace social support in the context of French hospitals. Concrete, the first objective of this article comprises a thorough conceptualization and operationalization of workplace social support (i.e. both professional and personal social support). Data were collected in a French hospital among a sample of 62 respondents (for the qualitative part of our study), and among a sample of 171 health care professionals (nurses and nurse aids) (for the quantitative part of our study). Our outcomes indicate that, especially, personal support given by one's supervisor is strongly and positively related to nurses' and nurse aides' affective commitment. After a discussion about the outcomes, followed by some recommendations for future research, the article concludes with some practical implications for management in hospitals
Cotangent models of integrable systems

We associate cotangent models to a neighbourhood of a Liouville torus in symplectic and Poisson manifolds focusing on b-Poisson/b-symplectic manifolds. The semilocal equivalence with such models uses the corresponding action-angle theorems in these settings: the theorem of Liouville–Mineur–Arnold for symplectic manifolds and an action-angle theorem for regular Liouville tori in Poisson manifolds (Laurent- Gengoux et al., IntMath Res Notices IMRN 8: 1839–1869, 2011). Our models comprise regular Liouville tori of Poisson manifolds but also consider the Liouville tori on the singular locus of a b-Poisson manifold. For this latter class of Poisson structures we define a twisted cotangent model. The equivalence with this twisted cotangent model is given by an action-angle theorem recently proved by the authors and Scott (Math. Pures Appl. (9) 105(1):66–85, 2016). This viewpoint of cotangent models provides a new machinery to construct examples of integrable systems, which are especially valuable in the b-symplectic case where not many sources of examples are known. At the end of the paper we introduce non-degenerate singularities as lifted cotangent models on b-symplectic manifolds and discuss some generalizations of these models to general Poisson manifolds.Peer ReviewedPostprint (author's final draft
Radiographers practice concerning breast compression in mammography: gradual versus no gradual

Purpose: Evaluate the type of breast compression (gradual or no gradual) that
provides less discomfort to the patient. Methods and Materials: The standard projections were simulated [craniocaudal/(CC) and mediolateral-oblique/(MLO)] with the two breast compressions in 90 volunteers women aged between 19 and 86. The women were organised in groups according to the breast density. The intensity of discomfort was evaluated using the scale that have represented several faces (0-10) proposed by Wong Baker in the end of each simulation. It was also
applied an interview using focus group to debate the score that were attributed during pain evaluation and to identify the criteria that were considered to do the classification. Results: The women aged between 19-29y (with higher breast density)
classified the pain during no gradual compression as 4 and the gradual compression as 2 for both projections. The MLO projection was considered the most uncomfortable. During the focus group interview applied to this group was highlighted that compression did not promoted pain but discomfort. They considered that the high expectations of pain did not correspond to the discomfort that they felt. Similar results were identified for the older women (30-50y; > 50y). Conclusion: The radiographers should considerer the technique for breast compression. The gradual compression was considered for the majority of the women as the most comfortable regardless of breast density. The MLO projection was considered as uncomfortable due to the positioning (axila and inclusion of pectoral muscle) and due to the higher breast compression compared to the CC projection
Search for extra dimensions using diphoton events in 7 TeV proton-proton collisions with the ATLAS detector ATLAS collaboration

Using data recorded in 2011 with the ATLAS detector at the Large Hadron Collider, a search for evidence of extra spatial dimensions has been performed through an analysis of the diphoton final state. The analysis uses data corresponding to an integrated luminosity of 2.12 fb(-1) of root s = 7 TeV proton-proton collisions. The diphoton invariant mass (m(gamma gamma)) spectrum is observed to be in good agreement with the expected Standard Model background. In the large extra dimension scenario of Arkani-Hamed, Dimopoulos and Dvali, the results provide 95% CL lower limits on the fundamental Planck scale between 2.27 and 3.53 TeV, depending on the number of extra dimensions and the theoretical formalism used. The results also set 95% CL lower limits on the lightest Randall-Sundrum graviton mass of between 0.79 and 1.85 TeV, for values of the dimensionless coupling k/(M) over bar (Pl) varying from 0.01 to 0.1. Combining with previously published ATLAS results from the dielectron and dimuon final states, the 95% CL lower limit on the Randall-Sundrum graviton mass for k/(M) over bar (Pl) = 0.01 (0.1) is 0.80 (1.95) TeV
Search for anomalous production of prompt same-sign lepton pairs and pair-produced doubly charged higgs bosons with root s=8 Tev pp collisions using the ATLAS detector

Çetin, Serkant Ali (Dogus Author)A low-background inclusive search for new physics in events with same-sign dileptons is presented. The search uses proton-proton collisions corresponding to 20.3 fb(-1) of integrated luminosity taken in 2012 at a centre-of-mass energy of 8TeV with the ATLAS detector at the LHC. Pairs of isolated leptons with the same electric charge and large transverse momenta of the type e(+/-) e(+/-), e(+/-) mu(+/-), and mu(+/-) mu(+/-) are selected and their invariant mass distribution is examined. No excess of events above the expected level of Standard Model background is found. The results are used to set upper limits on the cross-sections for processes beyond the Standard Model. Limits are placed as a function of the dilepton invariant mass within a fiducial region corresponding to the signal event selection criteria. Exclusion limits are also derived for a specific model of doubly charged Higgs boson production
Organising Collective Action for Effective Environmental Management and Social Learning in Wales

The paper explored key factors that might lead to successful agri-environmental social learning and collective action in order to deliver landscape-scale resource management within agri-environment schemes. Using the theory of collective action as an analytical framework the paper examined findings from in-depth interviews with 20 members of two co-operative initiatives in Wales and two participatory workshops. Consideration of the theory helped in understanding how individuals come together to provide public goods, and the conditions that make this activity a success. Factors of importance for organising and delivering collective agri-environment schemes were: locally adaptable engagement strategies; working with group members previously known to each other; institutional arrangements that limited group size and which allowed groups to develop their own solutions and implementation rules; and external support offering the services of a local facilitator and funding for both planning and management stages. A clear finding from the research was the extent to which both business and social confidence can grow within such groups which opens up further development opportunities. The paper identifies key factors that could be used to encourage and enhance the success of co-operative groups in delivering landscape-scale agri-environment schemes. The research findings identify appropriate mechanisms for the design and delivery of collective agri-environment schemes and environment management in the UK, which can also be applied to other parts of Europe
