Svensk sammanfattningEfter mer än 50 år av utforskande av rymden och studier av ett växande antal kända nedslagskratrar på jorden så har bildandet av nedslagskratrar utvecklats från att anses vara en sällsynt geologisk företeelse till en fundamental del av jordens, och solsystemets, historia.I dag vet vi att nedslagskratrar är en av de vanligaste landformerna på himlakroppar i inre solsystemet, saImpact cratering was once considered a rare geological process of no, or little, importance to the evolution of the Solar System and planet Earth. After more than 50 years of space exploration and the discovery of numerous (~190 as of October 2016) impact structures on Earth, this view has changed, and it is now clear that impact craters are in fact one of the most common morphological features on

The purchasing strategies in the construction industry have been considered by many writers in construction management as short-term and arms-length. However, a different picture is portrayed in the manufacturing industry, where the purchasing strategies are mostly long-term to secure supply for production. Industrialized building is at the crossroad between construction and manufacturing, which rThe purchasing strategies in the construction industry have been considered by many writers in construction management as short-term and arms-length.

Liaison is a phenomenon of external sandhi that involves the production of a latent coda consonant (liaisonconsonant, LC) in prevocalic contexts (e.g. [z] in des [de] + ânes [an] → des ânes [dezan], (some) donkeys,but not in des [de] + poules [pul] → des poules [depul], (some) hens. The segmental content of the LC isthus dependent on the first word but produced as the onset of the second word: [de

Wikipedia has become a reference knowledge source for scores of NLP applications. One of its invaluable features lies in its multilingual nature, where articles on a same entity or concept can have from one to more than 200 different versions. The interlinking of language versions in Wikipedia has undergone a major renewal with the advent of Wikidata, a unified scheme to identify entities and their

Exceptionally preserved specimens of the Cambrian stem-group brachiopod Mickwitzia occidens Walcott, 1908 are described in detail from the Indian Springs Lagerstatte in Nevada, USA. Shell structure and preserved mantle setae from these specimens reveal a variable diagenetic (taphonomic) history and provide insight into the phylogenetic position of mickwitziids. Morphologic and morphometric compari

In 2018, an AI system named by its creator DABUS (Device for the Autonomous Bootstrapping of Unified Sentience) was credited by its creator to have independently invented a neural flame and a fractal container. According to its creator, DABUS is a ‘sentient artificial general intelligence can replicate all aspects of human cognition, including perception, creativity, consciousness, and sentience’

Denna artikel diskuterar arkivkällor med känslig information och behovet av olika etiska angreppssätt. Avsikten med att lyfta dessa frågor är att frambringa en diskussion om hur historiker kan arbeta med känsligt material på ett etiskt sätt. Artikeln lyfter fram främst tre begrepp: processetik, omsorgsetik och dygdetik.In comparison to disciplines within the humanities and social sciences working directly with living humans, as well as in comparison to oral history, historians primarily working with archival sources lack a living discussion on ethics in connection with our methods. At the same time, archival sources that contain sensitive personal information are central in many fields – such as queer history –

This chapter describes the Back to the Future (BTF) approach with illustrations of different data sets and their conclusions and stimulates the growth of such studies. The BTF Project included several studies that "discovered" old data sets, digitized them, carried out analyses and made data and analyses available in publications. An important aspect of the BTF approach is that the evidence of cha
