الوصف: The preservation of organic and human remains in Early Nordic Bronze Age mounds (1700 BCE -1100 BCE) permits new provenance work on this important period. Studies have shown that different mobility/non-mobility patterns were exercised by elite women during this time. To extend the database, we conducted strontium isotope analyses of the enamel from the second and third molars from the elite female grave from Ginderup in Thisted County, Denmark. Among other items, this grave included the textile remains of a possible corded skirt or fringed blanket. We complemented analyses of this woman’s enamel with strontium isotope analyses of the first molar from Grave B as well as osteological analysis of the individuals from Early Nordic Bronze Age Graves A, B and C. Our results revealed that the strontium isotope ratios obtained from the woman wearing a possible corded skirt yielded one local ratio (M2) and one non-local ratio (M3). The results from Grave B yielded a ratio which falls within the local baseline of present-day Denmark. Our results suggest that the Ginderup Woman was probably of local origin, but that she also was repeatedly mobile during her life. These data are further evidence for the Nordic Bronze Age’s complex socio-dynamics.

الوصف: The Copernicus European Ground Motion Service (EGMS) provides consistent, regular, standardised, harmonised and reliable information regarding natural and anthropogenic ground motion phenomena over the Copernicus Participating States and across national borders, with millimetre accuracy. The EGMS is based on the multitemporal interferometric analysis of Sentinel-l radar images at full resolution. Global navigation satellite systems (GNSS) data are used to calibrate the interferometric measurements. EGMS provides an unprecedent opportunity to study geohazards and human-induced deformation over Europe, such as slow-moving landslides, natural subsidence or due to groundwater exploitation or underground mining activities, volcanic unrests and many other phenomena. This paper offers a first look at the products distributed by EGMS through relevant case studies in different environmental contexts of Europe. © 2022 IEEE. ; This work is part of the Spanish Grant SARAI, PID2020-116540RB-C21, funded by MCIN/AEI/ 10.13039/501100011033.

مصطلحات موضوعية: SAR, Persistent Scatterer Interferometry, Copernicus, European Ground Motion Service

الوصف: The Advanced Differential Interferometric SAR (A-DInSAR) technique is a class of powerful techniques to monitor ground motion. In the last two decades, the A-DInSAR technique has undergone an important development in terms of processing algorithms and the capability to monitor wide areas. This has been accompanied by an important increase of the Synthetic Aperture Radar (SAR) data acquisition capability by spaceborne sensors. An important step forward was the launch of the Copernicus Sentinel-1 constellation. The development of A-DInSAR based ground deformation services is now technically feasible. This paper describes some of the most important features of A-DInSAR. Then, it describes the European Ground Motion Service (EGMS), part of the Copernicus Land Monitoring Service, which represents a unique initiative for performing ground deformation monitoring on a European scale. ; This work has been partially funded by AGAUR, Generalitat de Catalunya, through the Consolidated Research Group RSE, "Remote Sensing" (Ref: 2017-SGR-00729).

By examining these new body of data as a whole, patterns may emerge. There is a scholarly movement which is beginning to go beyond producing evidence for movement/non-movement to starting to assess social strategies which may have caused mobility/non-mobility (Reiter & Frei 2019)

الوصف: Changes in funerary practices are key to the understanding of social transformations of past societies. Over the course of the Nordic Bronze Age, funerary practices changed from inhumation to cremation. The aim of this study is to shed light on this fundamental change through a cross-examination of archaeometric provenance data and archaeological discussions of the context and layouts of early cremation graves. To this end, we conducted 19 new provenance analyses of strontium isotopes from Early Nordic Bronze age contexts in Thisted County and Zealand and Late Bronze Age contexts from Thisted County and Vesthimmerland (Denmark). These data are subsequently compared with data from other extant relevant studies, including those from Late Bronze Age Fraugde on the Danish island of Fyn. Overall, the variations within our provenience data suggest that the integration and establishment of cremation may not have had a one-to-one relationship with in-migration to Nordic Bronze Age Denmark. Moreover, there seems to be no single blanket scenario which dictated the uptake of cremation as a practice within this part of Southern Scandinavia. By addressing habitus in relation to the deposition of cremations as juxtaposed with these provenance data¸ we hypothesize several potential pathways for the uptake of cremation as a new cultural practice within the Danish Nordic Bronze Age and suggest that this may have been a highly individual process, whose tempo may have been dictated by the specificities of the region(s) concerned.

الوصف: Background The gut microbiome is altered in patients with inflammatory bowel disease, yet how these alterations contribute to intestinal inflammation is poorly understood. Murine models have demonstrated the importance of the microbiome in colitis since colitis fails to develop in many genetically susceptible animal models when re-derived into germ-free environments. We have previously shown that Wiskott-Aldrich syndrome protein (WASP)-deficient mice (Was −/− ) develop spontaneous colitis, similar to human patients with loss-of-function mutations in WAS. Furthermore, we showed that the development of colitis in Was −/− mice is Helicobacter dependent. Here, we utilized a reductionist model coupled with multi-omics approaches to study the role of host-microbe interactions in intestinal inflammation. Results Was −/− mice colonized with both altered Schaedler flora (ASF) and Helicobacter developed colitis, while those colonized with either ASF or Helicobacter alone did not. In Was −/− mice, Helicobacter relative abundance was positively correlated with fecal lipocalin-2 (LCN2), a marker of intestinal inflammation. In contrast, WT mice colonized with ASF and Helicobacter were free of inflammation and strikingly, Helicobacter relative abundance was negatively correlated with LCN2. In Was −/− colons, bacteria breach the mucus layer, and the mucosal relative abundance of ASF457 Mucispirillum schaedleri was positively correlated with fecal LCN2. Meta-transcriptomic analyses revealed that ASF457 had higher expression of genes predicted to enhance fitness and immunogenicity in Was −/− compared to WT mice. In contrast, ASF519 Parabacteroides goldsteinii’s relative abundance was negatively correlated with LCN2 in Was −/− mice, and transcriptional analyses showed lower expression of genes predicted to facilitate stress adaptation by ASF519 in Was −/− compared to WT mice. Conclusions These studies indicate that the effect of a microbe on the immune system can be context dependent, with the same bacteria eliciting a ...

الوصف: This paper provides a discussion of the increasing amount of mobility data from the Early Nordic Bronze Age (Early NBA), c. 1600-1100 BCE with particular focus on NBA II and III (c. 1500-1100 BCE). As a male-oriented study, the intent is to develop current perspectives on gender roles in the Early NBA in relation to mobility. In order to achieve our aim, we conducted strontium isotope analyses and radiocarbon dating combined with an in-depth archaeological investigation of grave goods obtained from two male burials from the Vejle region, SE Jutland. To contextualise the case study results, we also conducted network analyses of male gear from burials and ritual deposits on a regional scale, which reveal differentiated roles among men in the upper social echelon. The warrior emerged as an overall identity for high-ranking males whilst differences in male weaponry interestingly suggest that a minimum of three kinds of warriors were distinguished, reflecting social roles in war and society. The results suggest that one of the individuals was local while the other might have moved. The overall aim is to demonstrate that robust results regarding gendered mobilities will depend on the combination of several methods, datasets and scales of inquiry.
