THRIVE elaborated
Introduction to THRIVE Elaborated:
Since we published the THRIVE framework a year ago in November 2014 it has generated a lot of
interest. We are delighted by this.
We want to take this opportunity to clarify and elaborate as relevant, including addressing areas of
potential confusion, as well as updating the document in light of our emerging thinking and elaboration
of elements of the framework.
It is important to note that nothing relating to the central ideas of the framework has
been changed
The SDSS Coadd: A Galaxy Photometric Redshift Catalog
We present and describe a catalog of galaxy photometric redshifts (photo-z's)
for the Sloan Digital Sky Survey (SDSS) Coadd Data. We use the Artificial
Neural Network (ANN) technique to calculate photo-z's and the Nearest Neighbor
Error (NNE) method to estimate photo-z errors for 13 million objects
classified as galaxies in the coadd with . The photo-z and photo-z
error estimators are trained and validated on a sample of
galaxies that have SDSS photometry and spectroscopic redshifts measured by the
SDSS Data Release 7 (DR7), the Canadian Network for Observational Cosmology
Field Galaxy Survey (CNOC2), the Deep Extragalactic Evolutionary Probe Data
Release 3(DEEP2 DR3), the VIsible imaging Multi-Object Spectrograph - Very
Large Telescope Deep Survey (VVDS) and the WiggleZ Dark Energy Survey. For the
best ANN methods we have tried, we find that 68% of the galaxies in the
validation set have a photo-z error smaller than . After
presenting our results and quality tests, we provide a short guide for users
accessing the public data.Comment: 16 pages, 13 figures, submitted to ApJ. Analysis updated to remove
proprietary BOSS data comprising small fraction (8%) of original
spectroscopic training set and erroneously included. Changes in results are
small compared to the errors and the conclusions are unaffected. arXiv admin

An Investigation of Sloan Digital Sky Survey Imaging Data and Multi-Band Scaling Relations of Spiral Galaxies (with Dynamical Information)
We have compiled a sample of 3041 spiral galaxies with multi-band gri imaging
from the Sloan Digital Sky Survey (SDSS) Data Release 7 and available galaxy
rotational velocities derived from HI line widths. We compare the data products
provided through the SDSS imaging pipeline with our own photometry of the SDSS
images, and use the velocities (V) as an independent metric to determine ideal
galaxy sizes (R) and luminosities (L). Our radial and luminosity parameters
improve upon the SDSS DR7 Petrosian radii and luminosities through the use of
isophotal fits to the galaxy images. This improvement is gauged via VL and RV
relations whose respective scatters are reduced by ~8% and ~30% compared to
similar relations built with SDSS parameters. The tightest VRL relations are
obtained with the i-band radius, R235i, measured at 23.5 mag/arcsec^-2, and the
luminosity L235i, measured within R235i. Our VRL scaling relations compare
well, both in scatter and slope, with similar studies (such comparisons however
depend sensitively on the nature and size of the compared samples). The typical
slopes, b, and observed scatters, sigma, of the i-band VL, RL and RV relations
are bVL=0.27+/-0.01, bRL=0.41+/-0.01, bRV=1.52+/-0.07, and sigmaVL=0.074,
sigmaRL=0.071, sigmaRV=0.154 dex. Similar results for the SDSS g and r bands
are also provided. Smaller scatters may be achieved for more pruned samples. We
also compute scaling relations in terms of the baryonic mass (stars + gas),
Mbar, ranging from 10^8.7 Msol to 10^11.6 Msol. Our baryonic velocity-mass (VM)
relation has slope 0.29+/-0.01 and a measured scatter sigma_meas = 0.076 dex.
While the observed VL and VM relations have comparable scatter, the stellar and
baryonic VM relations may be intrinsically tighter, and thus potentially more
fundamental, than other VL relations of spiral galaxies.Comment: Submitted to MNRAS, comments welcom

The SDSS Coadd: Cosmic Shear Measurement
Stripe 82 in the Sloan Digital Sky Survey was observed multiple times,
allowing deeper images to be constructed by coadding the data. Here we analyze
the ellipticities of background galaxies in this 275 square degree region,
searching for evidence of distortions due to cosmic shear. The E-mode is
detected in both real and Fourier space with - significance on
degree scales, while the B-mode is consistent with zero as expected. The
amplitude of the signal constrains the combination of the matter density
and fluctuation amplitude to be .Comment: 17 pages, 19 figures, submitted to ApJ. Analysis updated using

THRIVE framework for system change
What is the THRIVE Framework? The THRIVE Framework provides a set of principles for creating coherent and resource-efficient communities of mental health and wellbeing support for children, young people and families.It aims to talk about mental health and mental health support in a common language that everyone understands.The Framework is needs-led. This means that mental health needs are defined by children, young people and families alongside professionals through shared decision making. Needs are not based on severity, diagnosis or health care pathways
Function of the anion transporter AtCLC-d in the trans-Golgi network
Anion transporting proteins of the CLC type are involved in anion homeostasis in a variety of organisms. CLCs from Arabidopsis have been shown to participate in nitrate accumulation and storage. In this study, the physiological role of the functional chloride transporter AtCLC-d from Arabidopsis was investigated. AtCLC-d is weakly expressed in various tissues, including the root. When transiently expressed as a GFP fusion in protoplasts, it co-localized with the VHA-a1 subunit of the proton-transporting V-type ATPase in the trans-Golgi network (TGN). Stable expression in plants showed that it co-localized with the endocytic tracer dye FM4-64 in a brefeldin A-sensitive compartment. Immunogold electron microscopy confirmed the localization of AtCLC-d to the TGN. Disruption of the AtCLC-d gene by a T-DNA insertion did not affect the nitrate and chloride contents. The overall morphology of these clcd-1 plants was similar to that of the wild-type, but root growth on synthetic medium was impaired. Moreover, the sensitivity of hypocotyl elongation to treatment with concanamycin A, a blocker of the V-ATPase, was stronger in the clcd-1 mutant. These phenotypes could be complemented by overexpression of AtCLC-d in the mutant background. The results suggest that the luminal pH in the trans-Golgi network is adjusted by AtCLC-d-mediated transport of a counter anion such as Cl− or NO3−

Loss of the interleukin-6 receptor causes immunodeficiency, atopy, and abnormal inflammatory responses
Abstract: IL-6 excess is central to the pathogenesis of multiple inflammatory conditions and this is targeted in clinical practice by immunotherapy that blocks the IL-6 receptor encoded by IL6R. We describe two patients with homozygous mutations in IL6R who presented with recurrent infections, abnormal acute phase responses, elevated IgE, eczema, and eosinophilia. This study identifies a novel primary immunodeficiency, clarifying the contribution of IL-6 to the phenotype of patients with mutations in IL6ST, STAT3 and ZNF341, genes encoding different components of the IL-6 signalling pathway, and alerts us to the potential toxicity of drugs targeting the IL-6R.J.E.D.T. is supported by the MRC (RG95376 and MR/L006197/1).

This research was made possible through access to the data and findings generated by two pilot studies for the 100,000 Genomes Project. The enrolment for one pilot study was coordinated by the NIHR BioResource (preprint from doi: https://doi.org/10.1101/507244) and the other by Genomics England Limited (GEL), a wholly owned company of the Department of Health in the UK. Over 90% of participants in the pilot studies have been enrolled in the NIHR BioResource. These pilot studies were mainly funded by grants from the National Institute for Health Research (NIHR) in England to the University of Cambridge and GEL, respectively. Additional funding was provided by the BHF, MRC, NHS England, the Wellcome Trust, amongst many other funders. The pilot studies use data provided by patients and their close relatives and collected by the NHS and other healthcare providers as part of their care and support.
