NICH: a preliminary theoretical study on Natural Interaction applied to Cultural Heritage contexts

Gesture-based interaction constitutes a new paradigm in human-machine interaction. The possibility to control a technical system with gestures on surfaces or in mid air makes it possible to design user interfaces that go beyond the WIMP paradigm (Windows Icons Menus and Pointers), the dominating interaction paradigm since the 1970's. After mainly having been of interest in the human-computer inter

Polarized-Light Processing in Insect Brains: Recent Insights from the Desert Locust, the Monarch Butterfly, the Cricket, and the Fruit Fly

The pattern of linearly polarized light in the sky can be used for orientation behavior by many insects. Although such behavioral responses have been well described in bees and ants over several decades, until recently it remained largely elusive how polarized-light information is processed in the insect brain. However, over the last decade, substantial advances in understanding polarized- light p

First principles methods for electronic structure calculations of solids

A straightforward gradient expansion of the exchange energy of a perturbed electron gas is performed. Studied perturbations range from very weak to those that produce, e.g., a silicon-like band structure with a band gap. The expansions involve density gradients up to fourth degree and we include all terms originating in linear- and second-order response theory. The expansion reproduces exactly cal

Regional Innovation Policy beyond ‘Best Practice’: Lessons from Sweden

This paper deals with policy measures in the regional innovation system of Scania, Southern Sweden. Focus is dedicated to requirements on innovation policy from actors representing different industries. Previous studies have identified profound differences with regard the organization of knowledge sourcing between firms and other actors in industries drawing on different knowledge bases. In corres

Studies for the Low Emittance MAX-IV Storage Rings

This thesis discusses the feasibility of a low emittance lattice proposed for the MAX-IV storage rings. The MAX-IV facility will have two storage rings that are identical but operated at two different energies, 1.5 GeV for soft X-ray and 3 GeV for hard X-ray production. The lattice is built to take advantage of the small gap insertion devices that imply small apertures in the magnet elements whic

Soil-living archaea: Influence of pH, carbon and nitrogen on their abundance and activity

Popular Abstract in Swedish På 70-talet upptäckte man att en grupp mikroorganismer, som man tidigare katalogiserat som bakterier, bildade en helt egen grupp. Dessa kallades ärkebakterier och fick senare namnet arkéer. Arkéer är små (ca 1 tusendels millimeter) encelliga organismer precis som bakterier, men de skiljer sig på många sätt från dem. Till exempel har de en kemiskt annorlunda uppbyggd celDuring the last decade it has been discovered that around 2% of the soil-living prokaryotes belong to the domain Archaea. In many soils the most abundant archaeal group is the ammonia-oxidizing archaea (AOA) that, in addition to ammonia-oxidizing bacteria (AOB), preform the first and rate-limiting step in the nitrification process. The knowledge of factors that regulates the archaeal abundance and

Helicobacter pylori cell surface interactions with glycosaminoglycans. Identification and characterisation of proteins binding to heparin/heparan sulphate.

Popular Abstract in Swedish Helicobacter pylori är en bakterie som orsakar såväl magkatarr, magsår som magsäckscancer. H. pylori producerar olika virulensfaktorer såsom enzymet ureas, ett cell vakuolbildande toxin (VacA), andra cytotoxiska proteiner (cagA eller pathogenicity island-associated proteins), flageller och adhesiner. För etablering av H. pylori infektion, måste dessa virulensfaktorer inHelicobacter pylori is a gastric pathogen which cause chronic type B gastritis and peptic ulcer disease. H. pylori produces virulence factors such as urease, vacuolating cytotoxin VacA, cag pathogenicity island-associated proteins, flagella and adhesins. These proteins interact with several host cell molecules such as sialylated cell surface glycoproteins, some of glycolipids and mucins. Glycosami
