We present simultaneous, quality fits to final BRAHMS, PHOBOS, STAR and PHENIX data on particle spectra and two-particle Bose-Einstein or HBT correlations as measured in Au+Au collisions at root(S)NN = 130 GeV. Using the Buda-Lund hydro model, the best fit is achieved when the most central 1/8th of the particle emitting volume is superheated to T > T-c = 170 MeV. In contrast, we find no indication
PURPOSE: To compare chemotherapy treatment monitoring in astrocytoma by 201thallium single photon emission computed tomography (SPECT) and photon magnetic resonance spectroscopy (1H-MRS) with magnetic resonance imaging (MRI), and to evaluate the influence of morphological tumor changes on cerebral 201thallium uptake and metabolic changes in 1H-MRS. MATERIALS AND METHODS: Six patients with highly m
The small Neogene Krong Pa graben is situated within the continental Song Ba Rift, which is bounded by strike-slip faults that were reactivated as extensional faults in Middle Miocene time. The 500 m thick graben-fill shows an overall depositional development reflecting the structural evolution, which is very similar to much larger and longer-lived graben. The basal graben-fill consists of thin fl
A patient undergoing cytostatic therapy for osteosarcoma of the right humerus had bone scans at 2-mo intervals. A skeletal focus of increased radiotracer accumulation occurred and subsequently was confirmed by CT and MRI. A necrotic metastasis was found during biopsy. There were no remaining viable tumor cells. This finding confirms the presence of the flare phenomenon in skeletal metastases in pr
Background Murray's Law states that, when a parent blood vessel branches into daughter vessels, the cube of the radius of the parent vessel is equal to the sum of the cubes of the radii of daughter blood vessels. Murray derived this law by defining a cost function that is the sum of the energy cost of the blood in a vessel and the energy cost of pumping blood through the vessel. The cost is minim
We tested the hypothesis that early brain recovery in hypoxic newborn piglets is improved by resuscitating with an O2 supply close to the minimum level required by the newborn piglet brain. Severely hypoxic 2-5-d-old anaesthetized piglets were randomly divided into three resuscitation groups: hypoxaemic (n = 8), 21% O2 (n = 8), and 100% O2 groups (n = 8). The hypoxaemic group was mechanically vent
Popular Abstract in Swedish Protein kinas C (PKC) är en familj serin/treonin kinaser som har en viktig roll i regleringen av olika funktioner i cellen. PKC kan delas in i klassiska (alpha, betaI, betaII and gamma), nya (delta, epsilon, eta and theta) och atypiska (zeta and iota/lambda) isoformer beroende på skillnader i hur de regleras. När PKCalpha är inaktivt bidrar intramolekylära bindningar tiMembers of the protein kinase C (PKC) family of serine/threonine kinases play critical roles in cellular regulation. Depending on differences in regulation, PKCs can be divided into classical (alpha, betaI, betaII and gamma), novel (delta, epsilon, eta and theta) and atypical (zeta and iota/lambda) isoforms. When PKCalpha is inactive it is maintained in a closed conformation by intramolecular inte

Popular Abstract in Swedish Föreliggande avhandling behandlar dynamiken hos styckvist hyperboliska system på begränsade mänder i planet och på intervallet. Avhandlingen är baserad på tre artiklar och därutöver annat stoff. I de två första artiklarna undersöks två olika klasser av styckvisa affina och hyperboliska avbildningar på begränsade mängder i planet. För båda dessa klasser gäller att tangeThis thesis is about dynamics of piecewise hyperbolic maps on bounded sets in the plane and on the interval. It is based on the following papers: T. Persson, A piecewise hyperbolic map with absolutely continuous invariant measure, Dynamical Systems: An International Journal, 21:3 (2006), 363--378 T. Persson, Absolutely continuous invariant measures for some piecewise hyperbolic affine maps, Prep
Laser-induced autofluorescence spectra from humans were recorded in vivo at three different clinics in a study aimed at investigating the capability of this method to discriminate between malignant tumours and normal surrounding tissues. For the recordings a mobile trolley with the necessary equipment was constructed for use in an examination room or in an operating theatre environment. Laser ligh
In this paper we show the density-dependent harvest rates of optimal Bayesian foragers exploiting prey occurring with clumped spatial distribution. Rodriguez-Girones and Vasquez (1997) recently treated the issue, but they used a patch-leaving rule (current value assessment rule) that is not optimal for the case described here. An optimal Bayesian forager exploiting prey whose distribution follows
This study examines the effect of three regimens (organizations of activities) on the realism in dyad’s confidence judgments. The effect of letting the pair members first work alone when selecting an answer and/or when confidence rating the correctness of this answer was compared with working directly in pairs. No improvement in the realism of the dyads’ final confidence judgments was found as an
Visits to nest holes by birds other than their owners is a familiar phenomenon for students of breeding biology. In this study, we evaluate that behavior using a transponder reading system. Eighty-five males and females were Fitted with transponders at the end of the incubation period or just after hatching. Nest boxes were fitted with transponder readers from just after hatching until all nestlin
