1. 1. Antonyms in Context : A Corpus-Based Semantic Analysis of Swedish Descriptive Adjectives

   Författare :Caroline Willners; Allmän språkvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; Nordiska språk språk och litteratur ; Scandinavian languages and literature; WordNet; semantic frameword; semantic network; sentential co-occurrence; semantic range; adjectives; antnoymy; lexical semantics; corpus-based methods; Lexicology; Lexikologi; Grammar; semantics; semiotics; syntax; Grammatik; semantik; semiotik;

   Sammanfattning : How are antonym relations acquired? What types of lexical information can be extracted from corpora and how? How can this information be encoded in a lexicon? The work in this book was developed within the framework of WordNet. A further elaborated lexical model is suggested, as well as methods for implementing it. LÄS MER

3. 2. Systems and Synthetic Biology: ​“Mining human gut microbial metabolism through in vitro and in silico approaches”

   Författare :Promi Das; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gut; bile acids; metatranscriptomics; in vitro co-cultures; metagenomics; co-occurrence network; short chain fatty acids; metabolomics; metabolism; vitamins;

   Sammanfattning : The human gut microbiome is a consequence of mutual co-evolutionary interaction between the eukaryotic and prokaryotic parts of the mammalian holobiont. Based on the environmental and dietary inputs, there is a succession of microorganisms living inside the human colon. LÄS MER

4. 3. Global functional association network inference and crosstalk analysis for pathway annotation

   Författare :Christoph Ogris; Erik Sonnhammer; Alfonso Valencia; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biological networks; genome wide functional association networks; global gene association networks; gene networks; protein networks; functional association; functional coupling; network biology pathway analysis; pathway annotation; pathway enrichment; network-based enrichment; enrichment; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

   Sammanfattning : Cell functions are steered by complex interactions of gene products, like forming a temporary or stable complex, altering gene expression or catalyzing a reaction. Mapping these interactions is the key in understanding biological processes and therefore is the focus of numerous experiments and studies. LÄS MER

5. 4. Regime Shifts in the Anthropocene

   Författare :Juan Carlos Rocha; Garry Peterson; Reinette Biggs; Örjan Bodin; Kevin Noone; Sarah Cornell; Ingo Fretzer; Steven Lade; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; regime shifts; critical transitions; network analysis; dynamic tipping points; Sustainability Science; vetenskap om hållbar utveckling; Systems Ecology; systemekologi;

   Sammanfattning : Regime shifts are large, abrupt and often hard to reverse changes in the function and structure of socal-ecological systems. These regime shifts have been documented in a broad range of systems and scales both in marine, terrestrial and polar ecosystems. LÄS MER

7. 5. Structural changes in marine ecosystems – the application of novel network approaches to understand marine regime shift

   Författare :Johanna Yletyinen; Thorsten Blenckner; Örjan Bodin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Anthropogenic drivers, such as climate change and fishing, have severe, often unexpected impacts on marine ecosystems. Species responses to drivers may have cascading effects through ecological communities, potentially changing the structure and functioning of the food web. LÄS MER
