Prototype Detector for Ultrahigh Energy Neutrino Detection

Necessary technical experience is being gained from successful construction and deployment of current prototype detectors to search for UHE neutrinos in Antarctica, Lake Baikal in Russia, and the Mediterranean. The prototype detectors have also the important central purpose of determining whether or not UHE neutrinos do in fact exist in nature by observation of at least a few UHE neutrino-induced leptons with properties that are not consistent with expected backgrounds. We discuss here the criteria for a prototype detector to accomplish that purpose in a convincing way even if the UHE neutrino flux is substantially lower than predicted at present.Comment: 18 pages, 8 figures, submitted to Astroparticle Physic

Explaining global surface aerosol number concentrations in terms of primary emissions and particle formation

We use observations of total particle number concentration at 36 worldwide sites and a global aerosol model to quantify the primary and secondary sources of particle number. We show that emissions of primary particles can reasonably reproduce the spatial pattern of observed condensation nuclei (CN) (R2=0.51) but fail to explain the observed seasonal cycle at many sites (R2=0.1). The modeled CN concentration in the free troposphere is biased low (normalised mean bias, NMB=−88%) unless a secondary source of particles is included, for example from binary homogeneous nucleation of sulfuric acid and water (NMB=−25%). Simulated CN concentrations in the continental boundary layer (BL) are also biased low (NMB=−74%) unless the number emission of anthropogenic primary particles is increased or an empirical BL particle formation mechanism based on sulfuric acid is used. We find that the seasonal CN cycle observed at continental BL sites is better simulated by including a BL particle formation mechanism (R2=0.3) than by increasing the number emission from primary anthropogenic sources (R2=0.18). Using sensitivity tests we derive optimum rate coefficients for this nucleation mechanism, which agree with values derived from detailed case studies at individual sites

Symptom burden and lived experiences of patients, caregivers and healthcare professionals on the management of malignant bowel obstruction: A qualitative systematic review

Background: Malignant bowel obstruction occurs in up to 50% of people with advanced ovarian and 15% of people with gastrointestinal cancers. Evaluation and comparison of interventions to manage symptoms are hampered by inconsistent evaluations of efficacy and lack of agreed core outcomes. The patient perspective is rarely incorporated. Aim: To synthesise the qualitative data regarding patient, caregiver and healthcare professionals’ views and experience of malignant bowel obstruction to inform the development of a core outcome set for the evaluation of malignant bowel obstruction. Design: A qualitative systematic review was conducted, with narrative synthesis. The review protocol was registered prospectively (https://www.crd.york.ac.uk/prospero, CRD42020176393). Data sources: MEDLINE, EMBASE, CINAHL, PsycINFO and Scopus databases were searched for studies published between 2010 and 2021. Reference lists were screened for further relevant publications, and citation tracking was performed. Results: Nine papers were included, reporting on seven studies which described the views and experiences of malignant bowel obstruction through the perspectives of 75 patients, 13 caregivers and 62 healthcare professionals. Themes across the papers included symptom burden, diverse experiences of interventions, impact on patient quality of life, implications and trajectory of malignant bowel obstruction, mixed experience of communication and the importance of realistic goals of care. Conclusion: Some of the most devastating sequelae of malignant bowel obstruction, such as pain and psychological distress, are not included routinely in its clinical or research evaluation. These data will contribute to a wider body of work to ensure the patient and caregiver perspective is recognised in the development of a core outcome set
