1. 1. A new generation density functional towards chemical accuracy

   Författare :Zhang Ying; Luo Yi; Head-Gordon Martin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioengineering; Bioteknik;

   Sammanfattning : Density functional theory (DFT) has become the leading method in calculating theelectronic structures and properties from first principles. In practical applicationsof DFT in the frame work of Kohn-Sham (KS) method, an approximate exchange-correlation functional has to be chosen. LÄS MER

3. 2. Bacterial Degradation and Use of Chitin in Aquatic Habitats

   Författare :Sara Beier; Stefan Bertilsson; Ian Head; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chitin; organic matter degradation; microbial ecology; functional guild; Biology; Biologi;

   Sammanfattning : Chitin belongs to the most abundant biopolymers on earth where it has an important role as a structural element in crustaceans, insects, fungi and some phytoplankton. Missing evidence for long-term accumulation of chitin in nature implies fast turnover and as chitin is composed of aminosugar subunits it holds central roles in both carbon and nitrogen cycles.

4. 3. On the Relative Order of Adverbs in the I-domain: A study of English and Swedish

   Författare :Fabian Beijer; Engelska; []
   Nyckelord :HUMANIORA; HUMANITIES; Relativized Minimality; Starke 2001 ; Cinque 1999 ; Minimalist Program; PAROLE; BNC; functional sequence; functional projection; functional head; hierarchical order; Swedish; English; I-domain; AdvP; adverb phrase; adverb; adverbial; syntactic features; word order; merge; English language and literature; Engelska språk och litteratur ;

   Sammanfattning : This dissertation is a theoretical and empirical investigation of the ordering of adverbs in the I-domain. Within the generative-minimalist framework, adverbs have traditionally been analysed as adjuncts, adjoined to the syntactic structure in semantically appropriate positions (e.g. Jackendoff 1972).

5. 4. Autonomic Management of System of Systems Security

   Författare :Silia Maksuti; Jerker Delsing; Markus Tauber; Radu Grosu; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; System of Systems; Security; Self-Adaptation; Autonomic Management; Eclipse Arrowhead; Cyberfysiska system; Cyber-Physical Systems;

   Sammanfattning : The digitalization of manufacturing industry and the profound reliance on interconnected System of Systems (SoS) is demanding for innovative solutions that can handle production processes, while making use of the new data that is being generated by various connected devices. Innovations based on collecting, evaluating, and using this data can improve existing processes and create new business models. LÄS MER

7. 5. Modeling glioblastoma heterogeneity to decipher its biology

   Författare :Yuan Xie; Lene Uhrbom; Massimo Squatrito; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioblastoma multiforme; biobank; GBM cells; cell of origin; LGR5; OPCs;

   Sammanfattning : Glioblastoma multiforme (GBM) is the most common and lethal form of primary brain tumor that mainly affects adults. GBM displays remarkable intra- and inter-tumoral heterogeneity and contains a subpopulation of cells named glioma stem cells that is believed to be responsible for tumor maintenance, progression and recurrence.
