A Comparison of CPU and GPU Implementations for the LHCb Experiment Run 3 Trigger

The Large Hadron Collider beauty (LHCb) experiment at CERN is undergoing an upgrade in preparation for the Run 3 data collection period at the Large Hadron Collider (LHC). As part of this upgrade, the trigger is moving to a full software implementation operating at the LHC bunch crossing rate. We present an evaluation of a CPU-based and a GPU-based implementation of the first stage of the high-level trigger. After a detailed comparison, both options are found to be viable. This document summarizes the performance and implementation details of these options, the outcome of which has led to the choice of the GPU-based implementation as the baseline.

Sensitivity of scale resolving aft-body flow simulations to numerical model parameter variations

The sensitivity of hybrid RANS-LES methods like Improved Delayed Detached Eddy Simulation (IDDES) to numerical model parameter variations related to generic space launch vehicle aft-body flows is investigated. In particular, the changes resulting from the choice of the time-step size, the turbulence model, the fluid modelling, the circumferential grid resolution, the filter length definition, and the data collection period is considered. The results are also compared to experimental and numerical data taken from the available literature. The sensitivity to the time-step size and the turbulence model is minuscule with respect to the obtained mean flow field, wall pressure distributions, azimuthal modes, and wall pressure frequency spectra. However, circumferential resolution, fluid model, and filter length definition affect the solution to a higher extent. Buffeting spectra are very sensitive to the data collection period.

Process Evaluation of a Mixed Methods Feasibility Study to Identify Hospital Patients with Palliative Care Needs in Portugal

Introduction: Evidence shows most patients are not recognised by their attending healthcare professionals as having palliative needs. This feasibility study aimed to aid healthcare professionals identify hospital patients with palliative needs.Material and Methods: Mixed-methods, cross-sectional, observational study. The patient inclusion criteria comprised: age over 18 years old, being mentally capable to give consent judged as such by participating healthcare professionals, and if unable, having a legal substitute to consent, having a diagnosis of an incurable, potentially life-threatening illness. Field notes were taken for reflexive purposes. Outcome measures included: Integrated Palliative Care Outcome scale, surprise question, phase of illness, referral request status, The Eastern Cooperative Oncology Group Performance Status and social needs assessment. An interim data collection period meeting assessed implementation outcomes in each context. A web-based survey was sent to all participating healthcare professionals at the end of data collection period to explore overall experiences of participation and implementation outcomes.Results: Forty-two departments in four hospitals were contacted. The study was presented in nine departments. The field notes were vital to understand the recruitment process and difficulties experienced: time constraints, fear of additional work, department dynamics and organisation, relationships between departments and need of training in palliative care and research. One department agreed to participate. There were six participating healthcare professionals and only 45 patients included. Three participating healthcare professionals responded to the web-based survey.Discussion: The response rate was very low. Legislating palliative care is not enough, and an integrated palliative care plan needs to be implemented at country and institution level.Conclusion: There is an urgent need to provide generalist palliative care training to clinicians.

Prevalence and Comparisons of Alcohol, Candy, Energy Drink, Snack, Soda, and Restaurant Brand and Product Marketing on Twitch, Facebook Gaming, and YouTube Gaming

Objective: To compare and evaluate the prevalence of food and beverage marketing on the livestreaming platforms Twitch, Facebook Gaming, and YouTube Gaming, as well as examine growth of food and beverage marketing on these platforms over a 17-month period of data collection.Design: Cross-sectional data was analyzed across three livestreaming platforms and six food and beverage categories: alcohol, candy, energy drinks, snacks, sodas, and restaurants.Setting: Stream titles of livestreamed events as well as corresponding hours watched on Twitch, Facebook Gaming, and YouTube Gaming.Participants: NoneResults: There were significant differences between food and beverage brand mentions across all three studied platforms (p<0.05), as well as hours watched (p<0.05). Energy drinks dominated food and beverage brand mentions across platforms, followed by restaurants, soda, and snacks. All platforms demonstrated growth over the 17-month data collection period. Post-hoc analyses revealed that the COVID-19 pandemic impacted both immediate and sustained growth across all platforms, with the greatest impact observed on the Twitch platform.Conclusions: Food and beverage marketing as measured through stream titles is widely prevalent across the three most popular livestreaming platforms, particularly for energy drinks. Food marketing on these platforms experienced growth over the past 17-months which was accelerated substantially by the COVID-19 pandemic. Future work should assess the sustained impact this growth may have on marketing practices and eating behavior.

DIGITALISATION OF THE HUMAN RESOURCES DEPARTMENT

The new digital trends are triggering the interest in the evolution of the future of work. The use of digitalisation in various sectors of activity has become an essential element in the success of organisations. An important role within organisations is played by the human resources department, seen as a business partner. It has the task of using the tools appropriate to the transformations existing on the labour market and meet the challenges posed by the new generations, but also globalisation. Thus, the purpose of this paper was to identify how human resources specialists relate to digital technologies and what are the advantages of using it. The research involved 40 subjects working in the field, in companies in the counties of Iasi, Suceava, Bucharest and Cluj. We found that the digitalisation of the human resources department means for the chosen sample, the increase of work efficiency and the implementation of technical measures to allow the proper functioning of technologies. The research method used in this paper was the sociological survey. The tool used was the online questionnaire, the data collection period being May - June 2020.

Content Themes and Influential Voices Within Vaccine Opposition on Twitter, 2019

Objectives. To report on vaccine opposition and misinformation promoted on Twitter, highlighting Twitter accounts that drive conversation. Methods. We used supervised machine learning to code all Twitter posts. We first identified codes and themes manually by using a grounded theoretical approach and then applied them to the full data set algorithmically. We identified the top 50 authors month-over-month to determine influential sources of information related to vaccine opposition. Results. The data collection period was June 1 to December 1, 2019, resulting in 356 594 mentions of vaccine opposition. A total of 129 Twitter authors met the qualification of a top author in at least 1 month. Top authors were responsible for 59.5% of vaccine-opposition messages. We identified 10 conversation themes. Themes were similarly distributed across top authors and all other authors mentioning vaccine opposition. Top authors appeared to be highly coordinated in their promotion of misinformation within themes. Conclusions. Public health has struggled to respond to vaccine misinformation. Results indicate that sources of vaccine misinformation are not as heterogeneous or distributed as it may first appear given the volume of messages. There are identifiable upstream sources of misinformation, which may aid in countermessaging and public health surveillance.

P05 An audit of proton pump inhibitor prescribing, in adherence with the trust’s guidance, in gastro-oesophageal reflux disease

AimThe effectiveness of proton pump inhibitors (PPIs) have been demonstrated. Nevertheless, the choice of PPI that should be used is less absolute. The clinical effectiveness, availability of the formulation, co-morbidities, route of administration and lowest acquisition cost are all considerations that should be accounted for when determining the appropriate therapy. Current Trust guidance recommends lansoprazole capsules and oral dispersible tablets as the first line PPI, unless other indications preclude its use. Other UK hospitals have audited PPI prescribing and their findings highlight that adherence upon deployment was poor.1 2 This audit aims to assess if written outpatient prescriptions are adhering to the guidelines.MethodThis study was conducted prospectively in the outpatient pharmacy, between February and March 2019. The defined data collection period was 5 weeks, which included a 1-week pilot study. The accumulation of data involved reviewing all outpatient prescriptions, whereby PPIs were prescribed, noting if the Trust’s guidance on PPI prescribing was being adhered to. Data was collected via a structured pro forma to assess the percentage compliance against the three predetermined standards:Standard 1 - Is the PPI prescribed appropriate?Standard 2 - Is there a documented indication for the prescribed PPI?Standard 3 - Is the dose appropriate for the patient?ResultsThere were a total of 84 prescriptions received from 13 different specialties. The age range of patients was 1 month to 16 years with a mean (± median) age of 7.66 ± 7 years. The overall compliance with the Trust’s guidelines for standards 1, 2 and 3 were 76%, 88% and 100% respectively. The infant and toddler age group (28 days – 23 months) showed the least compliance in standard 1, the choice of appropriate PPI (63%). The most common indication was gastro oesophageal reflux disease. Paediatric Gastroenterology received the greatest number of prescriptions over the data collection period. 12% of prescriptions did not have a documented indication and the most common PPI prescribed in the outpatient pharmacy was lansoprazole, which accounted for 64 (77%) of the prescriptions.ConclusionThe findings in this study are synonymous to that of other audits conducted in UK hospitals, where compliance with PPI guidelines were explored. Possible factors that could be attributed to the low levels of adherence are problems with implementation, lack of enforcement of the guidelines, patient/guardian preferences and presence of enteral feeding tubes. Clinicians should monitor their prescribing and where applicable, switch patients who are currently on omeprazole suspension, to lansoprazole oral dispersible tablets/capsules. This could lead to significant monetary savings for the Trust.ReferencesDerbyshire Joint Area Prescribing Committee.

The UK national registry of ENT surgeons with coronavirus disease 2019

BackgroundENT surgeons are likely to be at high risk of coronavirus disease 2019 exposure.MethodsA national registry of UK ENT surgeons with suspected or confirmed coronavirus disease 2019 was created with the support of ENT UK. Voluntary entry was made by either the affected individual or a colleague, using a web-based platform.ResultsA four-month data collection period is reported, comprising 73 individuals. Coronavirus disease 2019 was test-confirmed in 35 respondents (47.9 per cent). There was a need for hospitalisation in two cases (2.7 per cent) and tragically one individual died. Symptom onset peaked in March. The majority suspected their exposure to have been in the workplace, with a significant proportion attributing their disease to a lack of personal protective equipment at a time before formal guidance had been introduced.ConclusionThe registry suggests that a significant number of ENT clinicians in the UK have contracted coronavirus disease 2019, and supports the need for tailored personal protective equipment guidance and service planning.
