We present a method to add confidence limits to level curves, drawn on a map of a Gaussian random surface, measured with or without error on a regular or irregular grid. The method is based on the conditional level crossing intensity measure for non-stationary Gaussian fields.
Med anledning av Leif Tibells 60-årsdag, utkom sent i höstas en "Festschrift" helt ägnad åt lavar. Det är en rejäl lunta på omkring 500 sidor med 32 artiklar författade på engelska av lichenologer från hela världen. Jag har försökt extrahera resultat och nyheter ur denna bok som har särskilt intresse för svensk lichenologi.
Urinary tract infections (UTIs) are clustered in certain individuals but the molecular basis of disease susceptibility is not known. A single gene was shown to control the susceptibility to acute pyelonephritis and renal scarring in mice. The IL-8 receptor homologue (mIL-8Rh) controls neutrophil function during acute infection and the mIL-8Rh deletion causes tissue damage through neutrophil entrap
There is a general lack of rapid, sensitive, and quantitative methods for the detection of differentiating human embryonic stem cells (hESCs). Using light microscopy and immunohistochemistry, we observed that morphological changes of differentiating hESCs precede any major alterations in the expression of several commonly used hESC markers (SSEA-3, SSEA-4, TRA-1-60, TRA-1-81, Oct-4, and Nanog). In
Structures the concept of flexibility by making clear distinctions in three generic dimensions, describes the use of the framework for manufacturing flexibility by working through a concrete example. The framework was presented in “Making manufacturing flexibility operational – part 1: a framework”, IMS, Vol. 6 No. 2. Makes distinctions between the concept of flexibility in the three generic dimen
BACKGROUND AND PURPOSE: The purpose of this study was to evaluate whether grafting of fetal neocortical tissue 1 week after focal brain ischemia improved behavioral outcome and reduced secondary thalamic atrophy. METHODS: One week after distal ligation of the right middle cerebral artery in spontaneously hypertensive male rats, blocks of fetal neocortex (embryonic day 17) were homografted to rats
Previous research suggests that an inclination to eat in response to unlabeled anxiety and a strong dependence on environmental stimuli are more common in overweight individuals than in normal-weight controls. In particular, individuals who habitually use food and eating in order to alleviate painful feelings have to face these feelings when dieting, unless they can be neutralised by psychological
Recently, the origins and pathways of cerebrovascular acetylcholine- and vasoactive intestinal polypeptide-containing nerves have been elucidated in detail in the rat: The sphenopalatine ganglion is the major source for postganglionic parasympathetic fibers to the vascular beds of the cerebral hemispheres. To clarify the functional role of the nerves on cerebral blood vessels in vivo, brain cortic
The epithelia are the avascular layers of cells that cover the environment-exposed surfaces of the body. It appears that T cells localize to selected sites in or adjacent to epithelia via the selective expression of adhesion molecules and chemokine receptors on T cells. These bind to counter-receptors and to chemokines expressed by epithelial cells. Recently, there has been an advance in our under
Earlier detailed studies of cnidarian planula larvae have revealed a simple nervous system but no eyes or identifiable light sensing structures. Here, we describe the planula of a box jellyfish, Tripedalia cystophora, and report that these larvae have an extremely simple organization with no nervous system at all. Their only advanced feature is the presence of 10-15 pigment-cup ocelli, evenly spac

We have predicted that in suitable multiple barrier structures without applied bias, the thermopower may change sign because of quantum transport process. We have performed detailed numerical calculation to show that the predicted thermopower anomaly can be experimentally observed. This thermopower anomaly does not violate thermodynamic laws.
In our previous genome-wide scan of Finnish nuclear families, obesity was linked to chromosome Xq24. Here we analyzed this 15-Mb region by genotyping 9 microsatellite markers and 36 single nucleotide polyp morphisms (SNPs) for 11 positional and functional candidate genes in an extended sample of 218 obese Finnish sibling pairs (sibpairs) (BMI > 30 kg/m(2)). Evidence of linkage emerged mainly from
The life histories of holo-anhydrobiotic animals differ from those of all other organisms by a regular or irregular entrance into an ametabolic state induced by desiccation. Such ametabolic periods will arrest growth and reproduction completely and thus affect primary life history parameters dramatically. The selective forces and the genetic and physiological trade-offs acting on anhydrobiotic ani
