Much research on dolphin echolocation has focused on animals that have been trained to remain stationary or to carry a device that allows the animals to move but restricts the location of the sonar beam. In such cases, a small number of hydrophones measures sonar characteristics while dolphins solve echolocation tasks. As a result, much is known about the beam axis but relatively little is known a
In industrialised countries atopic dermatitis (AD) is the most common chronic inflammatory disease among children. Many factors influence this disease in a negative way and contact allergy is one such factor. The aim of the study was to examine the frequency of contact allergy among children with the diagnosis AD in Malmö, Sweden and to evaluate if a significant degree of contact allergies in thes
Resolving the genetic basis of complex diseases like rheumatoid arthritis will require knowledge of the corresponding diseases in experimental animals to enable translational functional studies. Mapping of quantitative trait loci in mouse models of arthritis, such as collagen-induced arthritis (CIA), using F-2 crosses has been successful, but can resolve loci only to large chromosomal regions. Usi
The cross-section average (CA) augmentation approach of Pesaran (A simple panel unit root test in presence of cross-section dependence. Journal of Applied Econometrics 2007; 22: 265–312) and Pesaran et al. (Panel unit root test in the presence of a multifactor error structure. Journal of Econometrics 2013; 175: 94–115), and the principal components-based panel analysis of non-stationarity in idios
Branding är det begrepp som används för att beteckna det arbete som läggs ner för att bygga starka varumärken. Branding har allt mer kommit att handla om att bygga upp en identitet och en image kring verksamheter, för att på så vis skapa konkurrensfördelar. I litteraturen betonas vikten av att den valda identiteten ska förmedlas genom alla de kommunikationskanaler och kontaktytor som finns tillgänBranding is the term used to denote the work being done to build strong brands. Branding has increasingly come to focus on building an identity and a brand image around businesses to create competitive advantages. The literature emphasizes the importance of the selected identity to be communicated through all communication channels and interfaces available. Thus, branding can include everything fr
Plasma levels of islet cell cytoplasmic and cytotoxic antibodies were determined in 10 children with insulin-dependent diabetes mellitus (IDDM) treated with plasmapheresis shortly after diagnosis, and in 9 children with IDDM treated by conventional means alone. Islet cell cytoplasmic antibody (ICA) titers were determined by indirect immunofluorescence using unfixed sections of human pancreas, and
BACKGROUND: The first generation of genome sequence assemblies and annotations have had a significant impact upon our understanding of the biology of the sequenced species, the phylogenetic relationships among species, the study of populations within and across species, and have informed the biology of humans. As only a few Metazoan genomes are approaching finished quality (human, mouse, fly and w
A promising approach for upgrading the performance of an established low-bandgap solar technology without adding much cost is to deposit a high bandgap polycrystalline semiconductor on top to make a tandem solar cell. We use a transparent silver nanowire electrode on perovskite solar cells to achieve a semi-transparent device. We place the semi-transparent cell in a mechanically-stacked tandem con
Some theological schools consider the human conscience to be subordinate as a means to revelation of God’s nature compared to the biblical text. This can lead the reader of these texts to do violence to their own conscience by conforming it to the perceived biblical witness, although the two (the reader’s conscience and the biblical witness) can appear as in stark contrast to one another. A cognit
Vertical nanowire n-type (InAs) and p-type (GaSb) transistors are co-processed and co-integrated using a gate-last process, enabling short gate-lengths (Lg=40 nm) and allowing selective digital etching of the channel. Two different common gate-stacks, including various pre-treatments, were compared and evaluated. The process was optimized to achieve high n-type performance while demonstrating
We consider the problem of finding an event-based sampling scheme that optimizes the trade-off between average sampling rate and control performance in a linear-quadratic-Gaussian (LQG) control problem setting with output feedback. Our analysis is based on a recently presented sampled-data controller structure, which remains LQG-optimal for any choice of sampling scheme. We show that optimization
This paper has two purposes. The first purpose is methodological and aims to extend previous work on efficiency analysis by implementing a multiple-output stochastic ray frontier production function model. This model generalizes the single-output stochastic frontier model to multiple-input, multiple-output technologies and allows simultaneous estimation of technical efficiency and analysis of infl
