The article provides an overview of ongoing research and key characteristics of Cognitive Semiotics, an emerging field dedicated to the transdiciplinary study of meaning, involving above all researchers from semiotics, linguistics, developmental and comparative psychology and philosophy. The combination of the following features distinguishes it from other synthetic approaches: (a) integration of
To characterise geographical distribution and time trends of chronic kidney disease (CKD) mortality in the context of the epidemic of Mesoamerican nephropathy (MeN), likely related to occupational heat stress and other, unknown, factors.
This paper presents a hysteretic (sliding mode) control IC for a buck DC/DC converter for use as an envelope tracking power supply to increase the efficiency of an RF power amplifier. The IC integrates a high-bandwidth error amplifier, a comparator with hysteresis, and a high-side driver for an external N-channel power MOSFET. The total control loop delay using the implemented IC is 35ns, this is
Pilgrimage is an important element of Christianity right from the start, being rooted in the Jewish religion. Pilgrimage to sites in the Holy Land develops strongly in the fourth century as the sites are made accessible and are adorned with sanctuaries by the Emperor. The Cross of Christ becomes an important object of devotion to pilgrims, but the story of its discovery is considered by many schol
Popular Abstract in Swedish Hur gick det till när det svenska riket expanderade norrut och införlivade Hälsingland? Denna bok är uppställd som en generalhypotes över denna långt utdragna process, som tar sin utgångspunkt i den samhälleliga kollaps som är skönjbar under 500-talet. De inhemska maktstrukturer som gradvis byggdes upp efteråt kom under medeltidens inledande århundraden att få känna på In which way did the power structures of central Sweden expand into the territories north of the forest Ödmården during the Middle Ages? This text reads like a general hypothesis for this process, which attempts to incorporate all relevant elements in the Medieval landscape of power. The study area chosen is the province of Hälsingland. The chronological take-off is the 6th century AD, when settle
BACKGROUND: Microarray experiments are increasing in size and samples are collected asynchronously over long time. Available data are re-analysed as more samples are hybridized. Systematic use of collected data requires tracking of biomaterials, array information, raw data, and assembly of annotations. To meet the information tracking and data analysis challenges in microarray experiments we reimp
Möjligheterna att använda trä och andra brännbara material som ytskikt i t ex samlingslokaler är av brandtekniska skäl begränsad. Trots det har man ibland haft önskemål om att kunna använda dessa material och det har därför efter hand uppkommit vissa s k tumregler om var och hur mycket brännbart material som får användas. Med den utveckling av pyrolysmodeller inom CFD-program som har skett de sena
Kulturartikel om James Bond-seriens förändring sedan 1960-talet och förändringen i mottagandet av filmerna.
SUMMARY: Detecting a new area of contrast enhancement in or in the vicinity of a previously treated brain tumor always causes concern for both the patient and the physician. The question that immediately arises is whether this new lesion is recurrent tumor or a treatment effect. The differentiation of recurrent tumor or progressive tumor from radiation injury after radiation therapy is often a rad
