Correction to: The relevance of the interpersonal theory of suicide for predicting past-year and lifetime suicidality in autistic adults (Molecular Autism, (2022), 13, 1, (14), 10.1186/s13229-022-00495-5)

Following publication of the original article [1], the authors reported missing information in the ‘Acknowledgements’ section. The corrected ‘Acknowledgements’ section reads: We thank our participants for their generosity in taking part in the present research and for their helpful feedback towards this and future research. We would like to thank the ACORN panel at Bournemouth University for the funding this research, and our supportive colleagues. Special thanks goes to Rebecca Ellis for her patience in assisting with participant payments. We thank our colleagues at the Autism Research Centre who helped us recruit through their participant panel; the staff at Autistica who allowed us to advertise to their research network; moderators and owners of Facebook groups who were willing to let us advertise our study. Dr. Moseley thanks Dr. Sarah George, Dr. Helen Bolderston, and Dr. Cécile Bardon for their advice around ensuring the safety of participants, with especial thanks to Dr. Bardon for her warm encouragement. Finally, the authors remember all autistic people whose lives were lost to suicide, both within our participant cohort and the broader autistic community. The original article [1] has been updated

The Primordial Inflation Explorer (PIXIE): A Nulling Polarimeter for Cosmic Microwave Background Observations

The Primordial Inflation Explorer (PIXIE) is an Explorer-class mission to measure the gravity-wave signature of primordial inflation through its distinctive imprint on the linear polarization of the cosmic microwave background. The instrument consists of a polarizing Michelson interferometer configured as a nulling polarimeter to measure the difference spectrum between orthogonal linear polarizations from two co-aligned beams. Either input can view the sky or a temperature-controlled absolute reference blackbody calibrator. PIXIE will map the absolute intensity and linear polarization (Stokes I, Q, and U parameters) over the full sky in 400 spectral channels spanning 2.5 decades in frequency from 30 GHz to 6 THz (1 cm to 50 um wavelength). Multi-moded optics provide background-limited sensitivity using only 4 detectors, while the highly symmetric design and multiple signal modulations provide robust rejection of potential systematic errors. The principal science goal is the detection and characterization of linear polarization from an inflationary epoch in the early universe, with tensor-to-scalar ratio r < 10^{-3} at 5 standard deviations. The rich PIXIE data set will also constrain physical processes ranging from Big Bang cosmology to the nature of the first stars to physical conditions within the interstellar medium of the Galaxy.Comment: 37 pages including 17 figures.

High-resolution calorimetry: limitations of doped semiconductor thermometers

Small thermal calorimeters operating at cryogenic temperatures have achieved an energy resolution for single X-ray photons that is a factor of 20 better than the theoretical limit for a silicon ionization detector. To determine the potential for further improvements and decide on likely routes for achieving them, we discuss detector design optimization, first for an ideal calorimeter, and then for the case where components exhibit non-ideal behavior. Two serious non-ideal properties of doped semiconductor thermometers are electron–phonon decoupling and excess noise. These have been characterized over a range of sensitivity and operating temperature, and their effects on design optimization and ultimate performance can be evaluated

Influences of nurses' scoring of children's postoperative pain

There is a lack of clarity as to why some nurses are not delivering optimal pain management to children post-operatively. This retrospective chart review study examined nurses’ pain scoring on 175 children during the first 24 hours post-operatively. Data were analysed on the amount of assessments made, assessment scores recorded, as well as the age, gender and type of surgery performed. One-quarter of children had no assessment record of their pain in the first 24 hours post-operatively. When the pain tool was part of an observation chart, nurses recorded more pain scores. Nurses’ scoring of children’s pain is influenced positively by children under five years of age and those who undergo abdominal surgery. Nurses who had access to one document for recording vital signs as well as pain scores were more likely to assess and record a child’s pain score than nurses who had to use a separate chart
