A moment problem for pseudo-positive definite functionals

A moment problem is presented for a class of signed measures which are termed pseudo-positive. Our main result says that for every pseudo-positive definite functional (subject to some reasonable restrictions) there exists a representing pseudo-positive measure. The second main result is a characterization of determinacy in the class of equivalent pseudo-positive representation measures. Finally the corresponding truncated moment problem is discussed.Comment: 23

Identifying domains of health-related quality of life: the perspective of individuals with low back pain

Abstract Background Identifying the most relevant HRQOL domains for LBP from the perspective of individuals with lived experience with LBP is necessary to prioritize domains that will be most informative for evaluating the impact of pain and interventions while overcoming the burden of using long-form assessment tools. This study aimed to identify which domains of HRQOL are most important from the perspective of individuals with chronic LBP. Methods Semi-structured interviews were conducted with 26 individuals with LBP. Participants first responded to questions related to the impact of their LBP on their HRQOL. Then, using a card sorting method, they were asked to select and indicate HRQOL domains that were most relevant to them from a list of 18 cards that represented different HRQOL domains. Participants were asked to explain the reasoning for their selection. Results Participants identified physical activity restriction (50%), severity of pain (31%), social activity restriction (23%), and work performance restriction (23%) as the most important domains. The most frequently selected HRQOL domains during card sorting were social function (69%), pain intensity (62%), physical function (58%), fatigue (58%), and pain interference (42%). Conclusion The most important domains of HRQOL perceived by participants were pain intensity, social function, physical function, fatigue, and pain interference. Identifying these domains will inform clinical decision-making and guide treatment choices for health care providers

Pigs and humans in Early Neolithic South-eastern Europe: New zooarchaeological and stable isotopic data from late 7th-early 6th millennium BC Džuljunica-Smărdeš, Bulgaria.

The Bulgarian site Džuljunica-Smărdeš, dating to 6205-5529 cal. BC, is one of the oldest Neolithic sites in Europe. Both domestic cattle and caprines are present in the zooarchaeological assemblage, but Sus, in contrast, is extremely rare. It is not known if the earliest Neolithic people in Europe did rear domestic pigs, practised some form of pig management, or only hunted wild boar. This research investigates the human pig relationships, using biometry, kill-off patterns and isotopic dietary analysis. With this integrated methodological approach, it might be possible to characterize human-suid relationships in this pivotal Early Neolithic site with greater accuracy. Understanding this relationship at this site contributes to the broader debate on how Neolithisation and domesticates spread through Europe, and which bio-cultural mechanisms were responsible for differential patterns of animal exploitation.Bioarchaeolog

Préhistoires méditerranéennes Hors Série Multilingual lexicon of bone industries Version 2 sous la direction d' Aline Averbouh

International audienceCe lexique multilingue a été établi dans le cadre des travaux du Groupement De Recherche Européen « Exploitation des matières osseuses dans l’Europe préhistorique » (GDRE PREHISTOS) du CNRS. Il est conçu comme un outil de travail qui vise à répertorier et à traduire dans les différentes langues parlées au sein du Groupement, les principaux termes - d’ordre technique, typologique ou fonctionnel - utilisés dans l’étude des industries en matières dures animales. Cette version fait suite à celle publiée en 2010 et propose une liste élargie de termes traduits en 12 langues (français, anglais, allemand, danois, espagnol, italien, portugais, roumain, bulgare, polonais, russe et hongrois)
