Background: The aims of this bibliometric analysis were (1) a longitudinal analysis of the publication landscape in the field of pain (1975–2020) and (2) to characterize the overall publication profiles for two selected journals: European Journal of Pain and PAIN® utilizing an automated approach. Methods: Database searches in Scopus extracted all journals with 'pain' in their title. For the two specific journals, papers were manually/automatically profiled into preclinical, human and translational studies. Results: A gross list of 64 journals in the field of pain consisting of both active and ceased journals in Scopus were included in this analysis which identified 62,565 papers with approximately 4000 papers published/year. These papers include 2759 and 9156 papers in Eur. J. Pain and PAIN®, respectively. Currently, there are 24 active 'pain' journals. Authors/paper increase from 2 to 7 indicating a development from mono‐disciplinary to multi‐disciplinary studies. The overall publication profiles assessing preclinical, human (experimental/clinical) and translational papers in Eur. J. Pain and PAIN® were almost similar (14%, 75% and 10% versus 26%, 63% and 10%). Papers have changed over the years from mono‐disciplinary studies (e.g. behavioural studies) to multi‐disciplinary studies (e.g. combined behavioural and cell studies). After optimization, the search model matched the manual screening by 100%, 98% and 96% for the preclinical, clinical and healthy volunteer categories. Conclusions: Over the last 45 years, more than 60,000 pain‐related papers have been published. Papers develop over the years from mono‐disciplinary to multi‐disciplinary studies. The overall publication profile including preclinical, human (experimental/clinical) and translational papers was almost similar in Eur. J. Pain and PAIN®. Significance: The bibliometric analysis of a pain journal provides information on which specific areas of research are published, how this may have changed over the years and how a journal is positioned compared with other journals in the field.

During machining of structural components, material inherent stresses are removed and additional residual stresses are induced into the subsurface of the workpiece. Both effects may result in distortions of the workpiece leading to shape deviations and time consuming repair processes. The research objective of this paper is to reduce part distortion caused by residual stresses of machined aircraft components by utilizing a distortion simulation in advance. The presented method is able to predict the part distortion caused by initial and process induced residual stresses. The results are verified in an experimental setup by comparison of measured and predicted distortions of a structural part. Based on the simulated results two basic strategies to minimize part distortion are described. Both strategies have a high potential for direct transfer into industrial application. In addition, three more advanced strategies with the objective of zero distortion are presented. [ABSTRACT FROM AUTHOR]

Paratuberculosis (Johne's disease) is a chronic infectious disease of ruminants, caused by Mycobacterium avium subspecies paratuberculosis (MAP). Because of its long incubation period, high economic losses, difficulties in diagnosis and possible links to Morbus Crohn in humans, paratuberculosis is one of the most important diseases of ruminants today. An abattoir-based nationwide survey on the occurrence of MAP in the Austrian cattle population was performed using serology (SVANOVIRTM-ELISA) as well as culture, ZN-stain and IS900-PCR on faeces and lymph node samples. A total of 756 Austrian slaughter cattle were serologically, bacteriologically and molecularbiologically tested for the occurrence of MAP and specific antibodies respectively. Samples were collected following a statistical plan to obtain balanced specimens from the whole country. Nineteen per cent of the animals tested were serological positive, 10.1% gave an inconclusive result and 70.9% showed no specific antibodies against MAP. Only in four individuals MAP could be detected by stain, bacteriology or Polymerase Chain Reaction. The calculated prevalence of 19.0% positive cattle, each representing one farm, showing specific antibodies against MAP is rather high in terms of animal-level but low in herd level prevalence compared with other countries. When this study is compared with a similar study performed in Austria 1999, a significant increase of positive cattle and farms could be seen in Austria. [ABSTRACT FROM AUTHOR]
