In this paper we determine the weak-interaction corrections of order αs α to hadronic top-quark pair production. First we compute the one-loop weak corrections to tt̄ production due to gluon fusion and the order αs α corrections to tt̄ production due to (anti)quark gluon scattering in the Standard Model. With our previous result [20] this yields the complete corrections of order αs α to gg, qq̄, q...

BACKGROUND The pathways of resistance to atazanavir (ATV) and amprenavir (APV) converge at position 50 of HIV protease. The determinants of cross-resistance were analysed during in vitro sequential or concomitant combination pressure with both drugs. METHODS Recombinant viruses containing in vitro and in vivo selected I50L and I50V proteases were constructed and cultured in increasing concent...

Yang [20] studies a deteriorating inventory model in which the supplier simultaneously offers the retailer either a conditional delay in payments or a cash discount. While considering the same inventory problem as that of Yang [20] in a systematic manner, the main purpose of this paper is twofold: First of all, since Yang [20] does not seem to have defined his inventory problem precisely, this ...

For the second time in the last three years the Skin Forum held its Annual Meeting in conjunction with the APV. This time the meeting took place in Prague at the IMG Conference Centre with the APV Headquarters in the form of Dr. Bornhöft and Ms. Schmidt leading the meeting organizational efforts. About 200 skin scientists attended the meeting and gave it, with their discussions in the lectures ...

Expectancy of future reward is an important factor guiding the speed of instrumental behavior. The present study sought to explore whether signals transmitted via the NMDA subtype of glutamate receptors and via dopamine D(2) receptors in the nucleus accumbens (NAc) are critical for the determination of reaction times (RTs) of instrumental responses by the expectancy of future reward. A simple R...

The EGNOS System Test Bed (ESTB) is the EGNOS prototype which has been broadcasting a Signal in Space since February 2000. Accuracy, integrity, continuity and availability are the main concepts in this European component of the Satellite Based Augmentation System which is designed to support en route through precision approach aircraft navigation. In this work, for the first half of the year of...

Forty-nine protease inhibitor (PI)-experienced but amprenavir (APV)-naïve patients experiencing virological failure were treated with ritonavir (RTV) (100 mg twice a day [b.i.d.]) plus APV (600 mg b.i.d.). Patients responded to therapy with a median viral load decrease of -1.32 log(10) by week 12. The addition of low-dose RTV enhanced the minimal APV concentration in plasma (APV C(min)) up to 1...

The electroluminescence (EL) at 1.54 μm of metal–oxide–semiconductor (MOS) devices withEr3C ions embedded in the silicon-rich silicon oxide (SRSO) layer has been investigated under different polarization conditions and compared with that of erbium doped SiO2 layers. EL time-resolved measurements allowed us to distinguish between two different excitation mechanisms responsible for the Er3C emiss...

The genes encoding the putative small hydrophobic (SH), attachment (G) and polymerase (L) proteins of the Colorado isolate of subgroup C avian pneumovirus (APV) were entirely or partially sequenced. They all included metapneumovirus (MPV)-like gene start and gene end sequences. The deduced Colorado SH protein shared 26.9 and 21.7 % aa identity with its counterpart in human MPV (hMPV) and APV su...

A paucity of information is available on the activity of protease inhibitors (PI) in chronically-infected monocyte-derived macrophages (MDM) and on the kinetics of viral-rebound after PI removal in vitro. To fill this gap, the activity of different concentrations of amprenavir (AMP) was evaluated in chronically-infected MDM by measuring p24-production every day up to 12 days after drug administ...
