This laboratory demonstrator setup is a downscaled version of a 7.5-maperture telescope with dual-conjugate adaptive optics, a representativestatic atmosphere in the K-band and five natural guide stars in a cross.The demonstrator has been used to evaluate different modes of adaptiveoptics; conventional single-conjugate adaptive optics, field-averagedsingle-conjugate adaptive optics and dual-conjug

Abstract This study attempts to understand what problem Isa 53 addresses and seeks to answer. The question is asked as an historical question and it is argued that Isa 53 address a specific historical problem, arising out of the conflicts created after the return of those who had gone into exile. At the end of the exile, there was hope that the deported people would return to the land, that the l

“The implications and applications of biotechnology continue to be at the centre of public debate. In the light of rapid scientific advances and novel insights, the multi-faceted discussions are particularly fierce with regard to patents on DNA–related technology. In the often very emotionally-led debate basically two directly conflicting schools of thoughts can be identified. Some people believe

Multiple-input multiple-output (MIMO) is a mandatory feature of the Third Generation Partnership Project (3GPP) Long Term Evolution. This work investigates the performance of a low complexity channel estimator for LTE terminals with an emphasis on the 4 × 4 multiple antenna scheme. The presented work extends a promising low-complexity 2 × 2 MIMO channel estimator to the 4 × 4 MIMO case and evaluat

We report preliminary clinical results of autofluorescence imaging of malignant and benign skin lesions, using pulsed 355 nm laser excitation with synchronized detection. The novel synchronized detection system allows high signal-tonoise ratio to be achieved in the resulting autofluorescence signal, which may in turn produce high contrast images that improve diagnosis, even in the presence of ambi

Det är både tekniskt möjligt och ekonomiskt genomförbart att ställa om till ett CO 2-snålt samhälle2050. Men för att nå en sådan målsättning måste ett antal utmaningar och hinder övervinnas, vilketkan kräva både politisk styrning och institutionell förändring.Denna rapport fokuserar specifikt på samspelet mellan utvecklingen av godstransporter, logistik ochCO 2-utsläpp. Godstransporterna, som styr

Popular Abstract in Swedish Tillväxtfaktorer påverkar signaler mellan celler i hjärnan Människors hjärnor innehåller flera miljarder hjärnceller, vilka är förutsättningen för vårt beteende, våra känslor och våra tankar. Hjärncellerna bildar kontakter, synapser, med varandra. Genom dessa överförs signaler från en cell till en annan. Varje cell kontaktar en mängd andra celler, både sådana med liknanThe neurotrophins, notably brain-derived neurotrophic factor (BDNF) and neurotrophin 3 (NT3), modulate synaptic transmission and synaptic plasticity in the adult mammalian brain. Recent data suggest that neurotrophins might be mediators of activity-dependent synaptic plasticity. Such plasticity is believed to be a cellular correlate for important processes like learning, but also for diseases, for

One of the major ways in which economic inequality can increase is when the development of wages of ordinary workers trail productivity and GDP growth, meaning that the increasing riches fall in the hand of other social groups (top employees, owners of land and capital). This paper investigates the relationship between wages and GDP in Denmark, Norway and Sweden from 1800 to 1910, using wage serie

The intense debate on continuity in child grammars has largely focused on the existence of Functional Categories (FCs) in early grammars despite differences in language use with adults (e.g., omissions, word order errors, lack of case marking). Simplified, the major theoretical explanations for these properties range from Maturational accounts (Radford 1990 and later) claiming an initial absence o
