In this paper, we present a new color buffer compression algorithm for floating-point buffers. It can operate in either an approximate (lossy) mode or in an exact (lossless) mode. The approximate mode is error-bounded and the amount of introduced accumulated error is controlled via a few parameters. The core of the algorithm lies in an efficient representation and color space transform, followed b

Abstract in Danish Denne artikel stiller skarpt på nogle af de fremtrædende neo-marxistiske teoretikere,der de seneste årtier har bidraget til vores forståelse af samfundet, den politiske økonomi, nye sociale bevægelser og rummet.

Biogeographic gradients may facilitate divergent evolution between populations of the same species, leading to geographic variation and possibly reproductive isolation. Previous work has shown that New Zealand triplefin species (family Tripterygiidae) have diversified in habitat use, however, knowledge about the consistency of this pattern throughout their geographic range is lacking. Here we exam

The article tells the modern love story of the organic grower Eduardo and the people who savor his apples. One remarkable paradigm shift when it comes to contemporary food culture is that the product’s social, political and cultural entanglements are no longer hidden from view. This new context has created platforms where producers and consumer come together to co-produce. Here, I broaden the conc

The neuropsychological network is a complex structure. To identify processes location and network capacity the brain imaging techniques together and in combination with other neuropsychological techniques and the expanding of well elaborated designs provide us with a multidimensional understanding, and contributes to the understanding of each illicit drug's character, which is of importance in des

Background: While simultaneous saccharification and co-fermentation (SSCF) is considered to be a promising process for bioconversion of lignocellulosic materials to ethanol, there are still relatively little demo-plant data and operating experiences reported in the literature. In the current work, we designed a SSCF process and scaled up from lab to demo scale reaching 4% (w/v) ethanol using xylos

In 2007, the European Commission (EC) commissioned a group of experts to undertake the revision of Report RP91 'Criteria for Acceptability of Radiological (including Radiotherapy) and Nuclear Medicine Installations' written in 1997. The revised draft report was submitted to the EC in 2010, which issued it for public consultation. The EC commissioned the same group of experts to consider the commen

The observed lifetimes of gaseous protoplanetary discs place strong constraints on gas and ice giant formation in the core accretion scenario. The approximately 10-Earth-mass solid core responsible for the attraction of the gaseous envelope has to form before gas dissipation in the protoplanetary disc is completed within 1-10 million years. Building up the core by collisions between km-sized plane

The feasibility of applying laser-induced phosphorescence in a combustion environment was shown by testing the consistency of the emission-temperature relations of thermographic phosphor particles (YAG:Dy). The relations were calibrated before and after the phosphor particles had passed a flame front. The calibrations were performed in air and in pure oxygen. The emission-temperature relation prev

Aims To describe the outcome of pregnancy in patients with structural or ischaemic heart disease. Methods and results In 2007, the European Registry on Pregnancy and Heart disease was initiated by the European Society of Cardiology. Consecutive patients with valvular heart disease, congenital heart disease, ischaemic heart disease (IHD), or cardiomyopathy (CMP) presenting with pregnancy were enrol

Diffusion of ion-implanted Mn in semi-insulating (SI) and liquid encapsulated Czochralski (LEC)-grown GaAs has been determined employing the modified radiotracer technique. The effect of the growth technique and conditions on Mn diffusion in low temperature molecular beam epitaxy (LT-MBE)-grown GaAs has also been studied. Two distinct diffusion components appear in ion-implanted Mn diffusion in Ga

Natural enemies exert selection pressure on their prey. Predators and parasitoids drive their prey into the evolution of novel traits to cope with this stress. When eggs and juveniles are the target of enemies, defense strategies may rely on adults. However, it is not easy to predict whether adults should actively protect unrelated offspring. Females of the golden egg bug (Phyllomorpha laciniata)

A cochlear implant (CI) is a device that provides individuals with severe to profound hearing impairment (SPHI) with auditory stimulation, which makes it possible for them to develop skills related to spoken communication. We have little knowledge about how hearing with a CI influences cognitive and communicative development and there is a need for development of methods for assessment. The genera

Interleukin (IL)-17 (now synonymous with IL-17A) is an archetype molecule for an entire family of IL-17 cytokines. Currently believed to be produced mainly by a specific subset of CD4 cells, named Th-17 cells, IL-17 is functionally located at the interface of innate and acquired immunity. Specifically, it induces the release of chemokines and growth factors from mesenchymal cells and is now emergi

Internationally there is an on-going political struggle regarding whether to define prostitution as violence, sex or work. In Sweden, however, the national law that bans purchase of sexual services, by defining prostitution as violence against women, has strong support. The aim of this article is to identify and describe claims-making and mobilisation on the Internet against Swedish prostitution p
