The overall designing of one 90nm CMOS reflective-type phase shifter for the first three channels in 60 GHz band is described. The performance investigation is based on full wave electromagnetic analysis and optimization. The simulation predicts a phase tuning range of 360° as a function of control voltage with an average insertion loss of 5.5 dB over all phase states. The linearity of the phase s

To support countries in reforming their research and innovation systems, the Directorate-General for Research & Innovation (DG RTD) of the European Commission set up a Policy Support Facility (PSF) under the European Framework Programme for Research & Innovation ‘Horizon 2020’. It aims to support Member States and associated countries in improving their national science, technology and inn

The degradation of the chemotherapy drug 5-fluorouracil by a non-pristine metal surfaces is studied. Using density functional theory, X-ray photoelectron spectroscopy and X-ray absorption spectroscopy we show that the drug is entirely degraded by medical-grade silver surfaces, already at body temperature, and that all of the fluorine has left the molecule, presumably as HF. Remarkably, this degrad

Cereal β-glucan is well known for its beneficial health effects, such as lowering of blood cholesterol values and a reduced risk of coronary heart disease. These effects are often discussed in relation to the dissolution and aggregation behavior of the β-glucan during human digestion. Furthermore, potential proteinaceous material present is believed to have an important impact on the formation of

One year ago, we discovered a new family of insect RYamide neuropeptides, which has the C-terminal consensus sequence FFXXXRYamide, and which is widely occurring in most insects, including the fruitfly Drosophila melanogaster and the red flour beetle Tribolium castaneum (F. Hauser et al., J. Proteome Res. 9 (2010) 5296-5310). Here, we identify a Drosophila G-protein-coupled receptor (GPCR) coded f

Expression of minigenes encoding tetra- or pentapeptides MXLX or MXLXV (E peptides), where X is a nonpolar amino acid, renders cells erythromycin resistant whereas expression of minigenes encoding tripeptide MXL does not. By using a 3A' reporter gene system beginning with an E-peptide-encoding sequence, we asked whether the codons UGG and GGG, which are known to promote peptidyl-tRNA drop-off at e

This chapter deals with the performance of commercial and financial services in Europe. Companies in both sectors have undergone considerable concentration in all analysed countries, but those from Great Britain, Germany, and France emerged as the largest companies in Europe from the early twentieth century onwards. Most impressive, however, has been the expansion of the size and business of banks

The integration of sociocultural valuations (SCV) within an ecosystem services (ES) framework is increasingly being required in environmental management contexts. Yet, this raises important questions: how do we approach SCV when people's perceptions are based on unbalanced information and advocate for detrimental actions? How then should SCV results be used? Should they be used to steer decisions?

Degradation of membrane phospholipids (PLs) is a well known phenomenon in acute brain injuries and is thought to underlie the disturbance of vital cellular membrane functions. In the present study glycerol, an end product of PL degradation, was examined in brain interstitial fluid as a marker of PL breakdown following experimental traumatic brain injury (TBI) using microdialysis. TBI was induced i

Melanoma represents a malignant disease with steadily increasing incidence. UV-irradiation is a recognized key factor in melanoma initiation. Therefore, the efficient prevention of UV tissue damage bears a critical potential for melanoma prevention. In this study, we tested the effect of UV irradiation of normal keratinocytes and their consequent interaction with normal and cancer-associated fibro

OBJECT: When evaluating the results of intracerebral microdialysis, the in vivo performance of the microdialysis probe must be considered, because this determines the fraction of the interstitial concentration obtained in the microdialysis samples. The in vivo performance is dependent on several factors, for example, the interstitial compartment's diffusion characteristics, which may vary during t

A new fully-integrated concurrent dual band CMOS power amplifier (PA) which covers the first and third channels of IEEE 802.15.3c standard is presented. In order to achieve concurrent operation of the 60 GHz PA in two desired narrow frequency bands, the multi-frequency passive coupling matching networks design is proposed. The full wave electromagnetic analysis (by the conventional Method of Momen

Enriched environments elicit brain plasticity in animals. In humans it is unclear which environment is enriching. Living in a city has been associated with increased amygdala activity in a stress paradigm, and being brought up in a city with increased pregenual anterior cingulate cortex (pACC) activity. We set out to identify geographical characteristics that constitute an enriched environment aff

The influences on gene expression by codons at positions +2, +3, +5 and +7 downstream of the initiation codon have been compared. Most of the +2 codons that are known to give low gene expression are associated with a higher expression if placed at the later positions. The NGG codons AGG, CGG, UGG and GGG, but not GGN or GNG (where N is non-G), are unique since they are associated with a very low g
