Who is in the transition gap? Transition from CAMHS to AMHS in the Republic of Ireland
Objective: The ITRACK study explored the process and predictors of transition between Child and Adolescent Mental Health Services (CAMHS) and Adult Mental Health Services (AMHS) in the Republic of Ireland. Method: Following ethical approval, clinicians in each of Ireland's four Health Service Executive (HSE) areas were contacted, informed about the study and invited to participate. Clinicians identified all cases who had reached the transition boundary (i.e. upper age limit for that CAMHS team ) between January and December 2010. Data were collected on clinical and socio-demographic details and factors that informed the decision to refer or not refer to AMHS and case notes were scrutinised to ascertain the extent of information exchanged between services during transition
Anti-Tumour Effect In Vitro of Lymphocytes and Macrophages from Mice Treated with Corynebacterium Parvum
Cells from the spleen, lymph node, peripheral blood and peritoneal exudate of mice treated with C. parvum were tested for their ability to inhibit tumour growth in vitro. The peritoneal exudate cells from C. parvum treated mice were extremely effective in inhibiting tumour growth whereas the spleen and peripheral blood cells were only moderately so. In contrast, the lymph node cells caused only a modest inhibition of tumour growth at a very high effector to target cell ratio. Spleen cells from normal mice also exerted a moderate anti-tumour effect
GoSam-2.0: a tool for automated one-loop calculations within the Standard Model and beyond
We present the version 2.0 of the program package GoSam for the automated
calculation of one-loop amplitudes. GoSam is devised to compute one-loop QCD
and/or electroweak corrections to multi-particle processes within and beyond
the Standard Model. The new code contains improvements in the generation and in
the reduction of the amplitudes, performs better in computing time and
numerical accuracy, and has an extended range of applicability. The extended
version of the "Binoth-Les-Houches-Accord" interface to Monte Carlo programs is
also implemented. We give a detailed description of installation and usage of
the code, and illustrate the new features in dedicated examples.Comment: replaced by published version and reference adde
Warped Phenomenology
We explore the phenomenology associated with the recently proposed localized
gravity model of Randall and Sundrum where gravity propagates in a
5-dimensional non-factorizable geometry and generates the 4-dimensional
weak-Planck scale hierarchy by an exponential function of the compactification
radius, called a warp factor. The Kaluza-Klein tower of gravitons which emerge
in this scenario have strikingly different properties than in the factorizable
case with large extra dimensions. We derive the form of the graviton tower
interactions with the Standard Model fields and examine their direct production
in Drell-Yan and dijet events at the Tevatron and LHC as well as the KK
spectrum line-shape at high-energy linear \epem colliders. In the case where
the first KK excitation is observed, we outline the procedure to uniquely
determine the parameters of this scenario. We also investigate the effect of KK
tower exchanges in contact interaction searches. We find that present
experiments can place meaningful constraints on the parameters of this model.Comment: 14 pages, LaTex, 3 fig
GoSam: A program for automated one-loop Calculations
The program package GoSam is presented which aims at the automated
calculation of one-loop amplitudes for multi-particle processes. The amplitudes
are generated in terms of Feynman diagrams and can be reduced using either
D-dimensional integrand-level decomposition or tensor reduction, or a
combination of both. GoSam can be used to calculate one-loop corrections to
both QCD and electroweak theory, and model files for theories Beyond the
Standard Model can be linked as well. A standard interface to programs
calculating real radiation is also included. The flexibility of the program is
demonstrated by various examples.Comment: 10 pages, Talk given at the International Workshop on Advanced

Observations on an apparent population extension of Glossina tachinoides Westwood in Southern Ivory Coast
Recent entomological surveys in the Bouaflé sleeping sickness focus of the Ivory Coast have revealed that Glossina tachinoides is considerably more widely distributed than hitherto. Some flies were found in the fringing riverine forests of tributaries of the River Marahoué. However, the greatest concentrations were found in villages and settlements where domestic pigs were kept. The southern limit of G. tachinoides now appears to lie one half degree of latitude further south than that reported by earlier investigators. The authors think there is good evidence that G. tachinoides is extending its range eastwards and southwards through and beyond the Bouaflé area, and the epidemiological significance of this is briefly discusse
Interaction of reed and acoustic resonator in clarinetlike systems
Sound emergence in clarinetlike instruments is investigated in terms of
instability of the static regime. Various models of reed-bore coupling are
considered, from the pioneering work of Wilson and Beavers ["Operating modes of
the clarinet", J. Acoust. Soc. Am. 56, 653--658 (1974)] to more recent modeling
including viscothermal bore losses and vena contracta at the reed inlet. The
pressure threshold above which these models may oscillate as well as the
frequency of oscillation at threshold are calculated. In addition to Wilson and
Beavers' previous conclusions concerning the role of the reed damping in the
selection of the register the instrument will play on, the influence of the
reed motion induced flow is also emphasized, particularly its effect on playing
frequencies, contributing to reduce discrepancies between Wilson and Beavers'
experimental results and theory, despite discrepancies still remain concerning
the pressure threshold. Finally, analytical approximations of the oscillating
solution based on Fourier series expansion are obtained in the vicinity of the
threshold of oscillation. This allows to emphasize the conditions which
determine the nature of the bifurcation (direct or inverse) through which the
note may emerge, with therefore important consequences on the musical playing
performances
Schottky mass measurements of heavy neutron-rich nuclides in the element range 70\leZ \le79 at the ESR
Storage-ring mass spectrometry was applied to neutron-rich Au
projectile fragments. Masses of Lu, Hf, Ta,
W, and Re nuclei were measured for the first time. The
uncertainty of previously known masses of W and Os nuclei
was improved. Observed irregularities on the smooth two-neutron separation
energies for Hf and W isotopes are linked to the collectivity phenomena in the
corresponding nuclei.Comment: 10 pages, 9 figures, 2 table
Maximising the power of deep extragalactic imaging surveys with the James Webb Space Telescope
We present a new analysis of the potential power of deep, near-infrared,
imaging surveys with the James Webb Space Telescope (JWST) to improve our
knowledge of galaxy evolution. In this work we properly simulate what can be
achieved with realistic survey strategies, and utilise rigorous signal:noise
calculations to calculate the resulting posterior constraints on the physical
properties of galaxies. We explore a broad range of assumed input galaxy types
(>20,000 models, including extremely dusty objects) across a wide redshift
range (out to z~12), while at the same time considering a realistic mix of
galaxy properties based on our current knowledge of the evolving population (as
quantified through the Empirical Galaxy Generator: EGG). While our main focus
is on imaging surveys with NIRCam, spanning lambda(obs) = 0.6-5.0 microns, an
important goal of this work is to quantify the impact/added-value of: i)
parallel imaging observations with MIRI at longer wavelengths, and ii) deeper
supporting optical/UV imaging with HST (potentially prior to JWST launch) in
maximising the power and robustness of a major extragalactic NIRCam survey. We
show that MIRI parallel 7.7-micron imaging is of most value for better
constraining the redshifts and stellar masses of the dustiest (A_V > 3)
galaxies, while deep B-band imaging (reaching~28.5 AB mag) with ACS on HST is
vital for determining the redshifts of the large numbers of faint/low-mass, z <
5 galaxies that will be detected in a deep JWST NIRCam survey.Comment: 19 Pages, 11 Figures, Submitted to MNRA
