Water, Communication, Sight, and the Location of Fortifications on the Strata Diocletiana (Syria) in Late Antiquity

The Strata Diocletiana was a military road in Late Roman Period Syria. It ran from Damascus to the Euphrates by way of Palmyra. The road was fortified and received its name during the reign of Diocletian (284–305 CE), following the Roman sack and subsequent garrisoning of Palmyra after the city’s failed revolt 272–273 CE. The Strata Diocletiana is only one of several attested routes between Palmyra and western Syria and one of two between Palmyra and Damascus. In this study, we seek to understand why this route was chosen for the new fortified road. We compare the location of Late Roman fortifications along the Strata Diocletiana to the modern distribution of water in the Syrian Desert and the theoretical least-cost paths between Palmyra and Damascus, and Palmyra and the fortress of Sura on the Euphrates. The argument is made that some parts of the Roman road network in the Syrian Desert were planned in order to control major water sources along the desert rim, but that the new military road between Damascus and Palmyra in the late third century CE was constructed with the aim of monitoring and controlling access to settled regions from the desert, in addition to ease and speed of communication. The conclusions have bearings not only on our understanding of the Late Roman defence and communication system, but also on nomad-settled interaction in Late Antiquity and the use of GIS methodologies in the reconstruction of ancient communication networks.publishedVersio

Assyrisk militarisme og terror

Festskrift til Johan Henrik Schreine

Antikke samfunn i krig og fred

Festskrift til Johan Henrik SchreinerDenne boken er er festskrift ril professor Johan Henrik Schreiner i forbindelse med hans 70-årsdag. Den består av en samling artikler 0111 krig, konflikt og fredsslurninger i antikken. Krigen er alle tings mor, kunne det hete da, og mens verdenslitteraturen ofte fører sin stamtavle tilbake ril Homer og hans beskrivelse av Trojanerkrigen, fører hisroriefaget sin tilbake til Herodots og Thukydides' verker om perserkrigene og Peloponneserkrigen. Fascinasjonen for greske bystaters borger- og krigerkollekriv og store generaler som Alexander og Caesar har dessuten holdt seg godt i to tusen år. Denne boken vil forhåpentligvis bidra til videre interesse. Her vil man finne belyst mange sider ved antikke samfunns forhold til krig - både svært omdiskuterte og nye, lite omtalte. Bidragene strekker seg fra Assyrerriker ved jernalderens begynnelse til det seinantikke Romerriket. Artiklene er ført i pennen av antikkhistorikere, arkeologer og klassiskfilologer ved norske og danske universitet. De er skrevet også med tanke på et alminnelig inreressert publikum og bør kunne interessere både leg og lærd

The FLUXNET2015 dataset and the ONEFlux processing pipeline for eddy covariance data

The FLUXNET2015 dataset provides ecosystem-scale data on CO2, water, and energy exchange between the biosphere and the atmosphere, and other meteorological and biological measurements, from 212 sites around the globe (over 1500 site-years, up to and including year 2014). These sites, independently managed and operated, voluntarily contributed their data to create global datasets. Data were quality controlled and processed using uniform methods, to improve consistency and intercomparability across sites. The dataset is already being used in a number of applications, including ecophysiology studies, remote sensing studies, and development of ecosystem and Earth system models. FLUXNET2015 includes derived-data products, such as gap-filled time series, ecosystem respiration and photosynthetic uptake estimates, estimation of uncertainties, and metadata about the measurements, presented for the first time in this paper. In addition, 206 of these sites are for the first time distributed under a Creative Commons (CC-BY 4.0) license. This paper details this enhanced dataset and the processing methods, now made available as open-source codes, making the dataset more accessible, transparent, and reproducible.Peer reviewe

A low-gluten diet induces changes in the intestinal microbiome of healthy Danish adults

\ua9 2018, The Author(s). Adherence to a low-gluten diet has become increasingly common in parts of the general population. However, the effects of reducing gluten-rich food items including wheat, barley and rye cereals in healthy adults are unclear. Here, we undertook a randomised, controlled, cross-over trial involving 60 middle-aged Danish adults without known disorders with two 8-week interventions comparing a low-gluten diet (2 g gluten per day) and a high-gluten diet (18 g gluten per day), separated by a washout period of at least six weeks with habitual diet (12 g gluten per day). We find that, in comparison with a high-gluten diet, a low-gluten diet induces moderate changes in the intestinal microbiome, reduces fasting and postprandial hydrogen exhalation, and leads to improvements in self-reported bloating. These observations suggest that most of the effects of a low-gluten diet in non-coeliac adults may be driven by qualitative changes in dietary fibres

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
