Lived experiences of routine antenatal dietetic services among women with obesity : a qualitative phenomenological study.

Objective\ud
to understand the lived experiences and views of being referred to an antenatal dietetic service from the perspective of pregnant women with obesity.\ud
\ud
Design\ud
a qualitative, interpretive approach using one-to-one in-depth interviews to explore the lived experience of pregnant women with obesity following referral to an antenatal dietetics service. Thematic content analysis was carried out by two researchers independently to develop data-driven themes.\ud
\ud
Setting\ud
one NHS Trust maternity and dietetic services, North East England, UK.\ud
\ud
Participants\ud
fifteen pregnant women with a booking body mass index ≥30 kg/m2 attending an obesity-specific antenatal dietetic service. All women were White, parity between 0 and 2, and BMI range 30–51 kg/m2.\ud
\ud
Findings\ud
four themes were identified. (1) Women's overall experience of the service: experiences were predominately positive with only two negative cases identified. (2) Process of referral: women placed importance on informative and in-person communication about the service, with health professionals, at the point of referral. (3) Delivery of the service: dietitians were considered to be the experts and women wanted more frequent contact. (4) Content of the service: tailored advice enabled behaviour change, and women desired increased physical activity support and weight monitoring.\ud
\ud
Key conclusions\ud
women reported an overall positive experience and thought that dietitians were the expert health professionals to support them. Women in this study felt that tailoring advice specific to their personal circumstances helped them implement changes, and had a strong interest in the nutritional benefits for fetal development. Women considered weight monitoring to be a positive element of the service; however, further research is required given the limited and conflicting evidence-base.\ud
\ud
Implications for practice\ud
it is important to incorporate women's experiences in the development and delivery of antenatal weight management services to facilitate person-centred care. Communication by health professionals at the point of referral is particularly important to provide accurate expectations of services and to reduce anxieties. Dietitians are considered to be appropriate experts to deliver these services, although they may need additional support to address women's physical activity needs in pregnancy
Observations of the blazar 3C 66A with the magic telescopes in stereoscopic mode

We report new observations of the intermediate-frequency peaked BL Lacertae object 3C 66A with the MAGIC telescopes. The data sample we use were taken in 2009 December and 2010 January, and comprises 2.3 hr of good quality data in stereoscopic mode. In this period, we find a significant signal from the direction of the blazar 3C 66A. The new MAGIC stereoscopic system is shown to play an essential role for the separation between 3C 66A and the nearby radio galaxy 3C 66B, which is at a distance of only 6'. The derived integral flux above 100 GeV is 8.3% of the Crab Nebula flux and the energy spectrum is reproduced by a power law of photon index 3.64 ± 0.39stat ± 0.25sys. Within errors, this is compatible with the one derived by VERITAS in 2009. From the spectra corrected for absorption by the extragalactic background light, we only find small differences between the four models that we applied, and constrain the redshift of the blazar to z < 0.68
The spectral type of CHS 7797 - an intriguing very low mass periodic variable in the Orion Nebula Cluster

Aims: We present the spectroscopic characterization of the unusual high-amplitude very low mass pre-main-sequence periodic variable CHS 7797. Methods: This study is based on optical medium-resolution (R = 2200) spectroscopy in the 6450 − 8600   Å range, carried out with GMOS-GEMINI -S in March 2011. Observations of CHS 7797 have been carried out at two distinct phases of the 17.8 d period, namely at maximum (I ≈ 17.4 mag) and four days before maximum (I ≈ 18.5 mag). Four different spectral indices were used for the spectral classification at these two phases, all of them well-suited for spectral classification of young and obscured late M dwarfs. In addition, the gravity-sensitive Na I (8183/8195 Å) and K I (7665/7699 Å) doublet lines were used to confirm the young age of CHS 7797. Results: From the spectrum obtained at maximum light we derived a spectral type (SpT) of M 6.05  ±  0.25, while for the spectrum taken four days before maximum the derived SpT is M 5.75  ±  0.25. The derived SpTs confirm that CHS 7797 has a mass in the stellar-substellar boundary mass range. In addition, the small differences in the derived SpTs at the two observed phases may provide indirect hints that CHS 7797 is a binary system of similar mass components surrounded by a tilted circumbinary disk, a system similar to KH 15D.Fil: Rodriguez Ledesma, María V..

Relating molecular morphology to charge mobility in semicrystalline conjugated polymers

Published: February 22, 2016The molecular-level origins of the effects of annealing temperature and molecular weight on hole mobility in P3HT are elucidated using coarse-grained molecular dynamics, quantum chemical calculations, and kinetic Monte Carlo charge-transport simulations on a variety of realistic thin-film morphologies. The zero-field hole mobility is shown to increase as the annealing temperature or average molecular weights of samples are increased, in accordance with experimental results. Crystal structure analysis shows that the annealing temperature dependence of the mobility can be attributed to the size and structural order of the crystallites in both the chain-backbone and π-stacking directions. However, the molecular weight dependence of the mobility cannot be rationalized in the same way. Longer chains are shown to belong to more crystallites in the morphology, suggesting that the crystals become better connected as the molecular weight of the sample increases. We show that engineering samples to have an increased fraction of these long “tie chains” within the morphology improves mobility. As such, we propose that crystal connectivity in the noncrystalline portions of the morphology is similarly important in determining carrier mobility as crystallite size and order for semicrystalline conjugated polymers.M.

New insights in contact allergy and drug delivery. A study of formulation effects and hapten targets in skin using two-photon fluorescence microscopy

The skin is a remarkable barrier, protecting us from invasion of e.g. harmful microorganisms and UV-radiation. However, the skin is not adopted to resist repeated exposure to the multitude of xenobiotics introduced into modern society. Some of these chemicals are skin sensitizers, and exposure can lead to the development of contact allergy. Contact allergy has significant social and economic consequences, both for the individual and for society. It is therefore important to prevent sensitization. The skin also constitutes a potential route for administration of drugs, and much effort is put into the development of cutaneous and transdermal drug delivery systems. 
The work of this thesis aims to improve the understanding of processes related to the interactions between the skin and topically applied compounds, i.e. drugs and skin sensitizers. Specifically, two-photon microscopy has been used to study the cutaneous absorption and distribution of model drugs and a series of model skin sensitizers. 
Improved cutaneous absorption was demonstrated using formulations composed of lipid cubic phases. The work also showed elevated sensitization potency of haptens depending on delivery vehicles. Putative mechanistic explanations for the observed effects have been proposed. Specifically, phthalates were shown to increase the sensitization potency of isothiocyanates. The phthalate-induced effect could be linked to a PSU-targeted delivery of the haptens into the skin. It could also be shown that vehicles alter hapten reactivity to stratum corneum proteins leading to variations in sensitization potency. Moreover, hapten protein targets in skin have been identified using caged fluorescent model hapten. Specifically, basal cell keratinocytes and the keratins were identified as specific hapten targets in the skin.
In conclusion, the work presented in this thesis contributes to the general understanding of the mechanisms involved in the cutaneous absorption of topically applied drugs and skin sensitizers. It also demonstrates the capabilities of using TPM when investigating the interactions between the skin and xenobiotics
Regulation of monocyte functional heterogeneity by miR-146a and Relb.

Monocytes serve as a central defense system against infection and injury but can also promote pathological inflammatory responses. Considering the evidence that monocytes exist in at least two subsets committed to divergent functions, we investigated whether distinct factors regulate the balance between monocyte subset responses in vivo. We identified a microRNA (miRNA), miR-146a, which is differentially regulated both in mouse (Ly-6C(hi)/Ly-6C(lo)) and human (CD14(hi)/CD14(lo)CD16(+)) monocyte subsets. The single miRNA controlled the amplitude of the Ly-6C(hi) monocyte response during inflammatory challenge whereas it did not affect Ly-6C(lo) cells. miR-146a-mediated regulation was cell-intrinsic and depended on Relb, a member of the noncanonical NF-κB/Rel family, which we identified as a direct miR-146a target. These observations not only provide mechanistic insights into the molecular events that regulate responses mediated by committed monocyte precursor populations but also identify targets for manipulating Ly-6C(hi) monocyte responses while sparing Ly-6Clo monocyte activity
Determinants of Sovereign Bond Yield Spreads in the EMU. An Optimal Currency Area Perspective

In the light of the recent financial crisis, we take a panel cointegration approach that allows for structural breaks to the analysis of the determinants of sovereign bond yield spreads in nine economies of the European Monetary Union. While we find evidence for a level break in the cointegrating relationship, we do not find empirical support for a regime shift and hence for a change in the pricing of the determinants of sovereign spreads. Moreover, results show that (i) fiscal imbalances (namely expected government debt-to-GDP differentials) are the main long-run drivers of sovereign spreads; (ii) liquidity risks and cumulated inflation differentials have non-negligible weights; but (iii) all conclusions are ultimately connected to whether or not the sample of countries is composed of members of an Optimal Currency Area (OCA). In particular, we establish (i) that results are overall driven by those countries not passing the OCA test; and (ii) that investors closely monitor and severely punish the deterioration of expected debt positions of those economies exhibiting significant gaps in competitiveness
Perceptions of organ donors and willingness to donate organs upon death : a test of the prototype/willingness model

Understanding people's organ donation decisions may narrow the gap between organ supply and demand. In two studies, participants who had not recorded their posthumous organ donation decision (Study 1, N = 210; Study 2, N = 307) completed items assessing prototype/willingness model (PWM; attitude, subjective norm, donor prototype favorability and similarity, willingness) constructs. Attitude, subjective norm, and prototype similarity predicted willingness to donate. Prototype favorability and a Prototype Favorability × Similarity interaction predicted willingness (Study 2). These findings provide support for the PWM in altruistic health contexts, highlighting the importance of people's perceptions about organ donors in their donation decisions
Estimating photometric redshifts for X-ray sources in the X-ATLAS field using machine-learning techniques

We present photometric redshifts for 1031 X-ray sources in the X-ATLAS field using the machine-learning technique TPZ. X-ATLAS covers 7.1 deg observed with XMM-Newton within the Science Demonstration Phase of the H-ATLAS field, making it one of the largest contiguous areas of the sky with both XMM-Newton and Herschel coverage. All of the sources have available SDSS photometry, while 810 additionally have mid-IR and/or near-IR photometry. A spectroscopic sample of 5157 sources primarily in the XMM/XXL field, but also from several X-ray surveys and the SDSS DR13 redshift catalogue, was used to train the algorithm. Our analysis reveals that the algorithm performs best when the sources are split, based on their optical morphology, into point-like and extended sources. Optical photometry alone is not enough to estimate accurate photometric redshifts, but the results greatly improve when at least mid-IR photometry is added in the training process. In particular, our measurements show that the estimated photometric redshifts for the X-ray sources of the training sample have a normalized absolute median deviation, nmad - 0.06, and a percentage of outliers, - = 10-14%, depending upon whether the sources are extended or point like. Our final catalogue contains photometric redshifts for 933 out of the 1031 X-ray sources with a median redshift of 0.9.The research leading to these results has received funding from the European Union’s Horizon 2020 Programme under the AHEAD project (grant agreement No. 654215).

Measurement of the production cross section of jets in association with a Z boson in pp collisions at √s = 7 TeV with the ATLAS detector

Measurements of the production of jets of particles in association with a Z boson in pp collisions at s√ = 7 TeV are presented, using data corresponding to an integrated luminosity of 4.6 fb[superscript −1] collected by the ATLAS experiment at the Large Hadron Collider. Inclusive and differential jet cross sections in Z events, with Z decaying into electron or muon pairs, are measured for jets with transverse momentum p [subscript T] > 30 GeV and rapidity |y| < 4.4. The results are compared to next-to-leading-order perturbative QCD calculations, and to predictions from different Monte Carlo generators based on leading-order and next-to-leading-order matrix elements supplemented by parton showers.United States.

B_s mixing phase and lepton flavor violation in supersymmetric SU(5)

We inspect consequences of the latest B_s mixing phase measurements on lepton
flavor violation in a supersymmetric SU(5) theory. The O(1) phase, preferring a
non-vanishing squark mixing, generically implies tau -> (e + mu) gamma and mu
-> e gamma. Depending on the gaugino and the scalar mass parameters as well as
tan beta, the rates turn out to be detectable or even already excessive, if the
RR mass insertion of down-type squarks is nonzero. We find that it becomes easy
to reconcile B_s mixing phase with lepton flavor violation given: gaugino to
scalar squared mass ratio around 1/12, both LL and RR insertions with decent
sizes, and low tan beta.Comment: 11 pages, updated using phi_s from HFAG, conclusion unchange
Pade-resummed high-order perturbation theory for nuclear structure
  calculations

We apply high-order many-body perturbation theory for the calculation of
ground-state energies of closed-shell nuclei using realistic nuclear
interactions. Using a simple recursive formulation, we compute the perturbative
energy contributions up to 30th order and compare to exact no-core shell model
calculations for the same model space and Hamiltonian. Generally, finite
partial sums of this perturbation series do not show convergence with
increasing order, but tend to diverge exponentially. Nevertheless, through a
simple resummation via Pade approximants it is possible to extract rapidly
converging and highly accurate results for the ground state energy.Comment: 6 pages, 2 figures, 1 tabl
Enhancements to the GW space-time method

We describe the following new features which significantly enhance the power
of the recently developed real-space imaginary-time GW scheme (Rieger et al.,
Comp. Phys. Commun. 117, 211 (1999)) for the calculation of self-energies and
related quantities of solids: (i) to fit the smoothly decaying time/energy
tails of the dynamically screened Coulomb interaction and other quantities to
model functions, treating only the remaining time/energy region close to zero
numerically and performing the Fourier transformation from time to energy and
vice versa by a combination of analytic integration of the tails and
Gauss-Legendre quadrature of the remaining part and (ii) to accelerate the
convergence of the band sum in the calculation of the Green's function by
replacing higher unoccupied eigenstates by free electron states (plane waves).
These improvements make the calculation of larger systems (surfaces, clusters,
defects etc.) accessible.Comment: 10 pages, 6 figure
Luminosity Function from dedicated SDSS-III and MMT data of quasars in
  0.7<z<4.0 selected with a new approach

We present a measurement of the quasar luminosity function in the range
0.68<z<4 down to extinction corrected magnitude g_dered=22.5, using a simple
and well understood target selection technique based on the time-variability of
quasars. The completeness of our sample was derived directly from a control
sample of quasars, without requiring complex simulations of quasar light-curves
or colors. A total of 1877 quasar spectra were obtained from dedicated programs
on the Sloan telescope (as part of the SDSS-III/BOSS survey) and on the
Multiple Mirror Telescope. They allowed us to derive the quasar luminosity
function. It agrees well with previously published results in the redshift
range 0.68<z<2.6. Our deeper data allow us to extend the measurement to z=4. We
measured quasar densities to g_dered<22.5, obtaining 30 QSO per deg^2 at z<1,
99 QSO per deg^2 for 1<z<2.15, and 47 QSO per deg^2 at z>2.15. Using pure
luminosity evolution models, we fitted our LF measurements, and predicted
quasar number counts as a function of redshift and observed magnitude. These
predictions are useful inputs for future cosmology surveys such as those
relying on the observation of quasars to measure baryon acoustic oscillations.Comment: 15 pages, 14 figs, accepted for publication in A&
Deformations of large N=(4,4) 2D SCFT from 3D gauged supergravity

Supersymmetric and non-supersymmetric deformations of large $N=(4,4)$ SCFT
with superconformal symmetry $D^1(2,1;\alpha)\times D^1(2,1;\alpha)$ are
explored in the gravity dual described by a Chern-Simons $N=8$, $(SO(4)\times
SO(4))\ltimes \mathbf{T}^{12}$ gauged supergravity in three dimensions. For
$\alpha>0$, the gauged supergravity describes an effective theory of the
maximal supergravity in nine dimensions on $AdS_3\times S^3\times S^3$ with the
parameter $\alpha$ being the ratio of the two $S^3$ radii. We consider the
scalar manifold of the supergravity theory of the form $SO(8,8)/SO(8)\times
SO(8)$ and find a number of stable non-supersymmetric $AdS_3$ critical points
for some values of $\alpha$. These correspond to non-supersymmetric IR fixed
points of the UV $N=(4,4)$ SCFT dual to the maximally supersymmetric critical
point. We study the associated RG flow solutions interpolating between these
fixed points and the UV $N=(4,4)$ SCFT. Possible supersymmetric flows to
non-conformal field theories are also investigated. Additionally, a
half-supersymmetric domain wall within this gauged supergravity is obtained.Comment: 32 pages, 4 figures, typos corrected and some changes in the

Algebraic Bethe ansatz for the XXX chain with triangular boundaries and
  Gaudin model

We implement fully the algebraic Bethe ansatz for the XXX Heisenberg spin
chain in the case when both boundary matrices can be brought to the
upper-triangular form. We define the Bethe vectors which yield the strikingly
simple expression for the off shell action of the transfer matrix, deriving the
spectrum and the corresponding Bethe equations. We explore further these
results by obtaining the off shell action of the generating function of the
Gaudin Hamiltonians on the Bethe vectors through the so-called quasi-classical
limit.Comment: 31 pages; typos correcte
Monopoles in Space-Time Noncommutative Born-Infeld theory

We transform static solutions of space-noncommutative Dirac-Born-Infeld
theory (DBI) into static solutions of space-time noncommutative DBI. Via
Seiberg-Witten map we match this symmetry transformation with a corresponding
symmetry of commutative DBI. This allows to: 1) study new BPS type magnetic
monopoles, with constant electric and magnetic background and describe them
both in the commutative and in the noncommutative setting; 2) relate by
S-duality space-noncommutative magnetic monopoles to space-noncommutative
electric monopolesComment: LaTeX, 6 pages. Talk presented at the Symposium: 100 Years Werner

Integration in the GHP formalism; 2, an operator approach for spacetimes with Killing vectors, with applications to twisting type n spaces

Held has proposed a coordinate- and gauge-free integration procedure within the GHP formalism built around four functionally independent zero-weighted scalars constructed from the spin coefficients and the Riemann tensor components. Unfortunately, a spacetime with Killing vectors will be unable to supply the full quota of four scalars of this type. However, for such a spacetime additional scalars are supplied by the components of the Killing vectors; by using these alongside the spin coefficients and the Riemann tensor components we have the possibility of constructing the full quota of four functionally independent zero-weighted scalars, and of exploiting Held's procedure. As an illustration we investigate the vacuum Type N spaces admitting a Killing vector and a homothetic Killing vector. In a direct manner, we reduce the problem to a pair of ordinary differential operator `master equations', making use of a new zero-weighted GHP operator. By first rewriting the master equations as a closed set of complex first order equations, we reduce the problem to one real third order operator differential equation for a complex function of a real variable --- but with still the freedom to choose explicitly our fourth coordinate. An alternative, more algorithmic approach, using a closed chain of real first order equations for real functions, reduces the problem to the same order, but in a more natural and much more concise form. It is also outlined how the various other third order differential equations, which have been derived previously by other workers on this problem, can be deduced from our master equations
