Limit distributions for the greatest convex minorant and its derivative are considered for a general class of stochastic processes including partial sum processes and empirical processes, for independent, weakly dependent and long range dependent data. The results are applied to isotonic regression, isotonic regression after kernel smoothing, estimation of convex regression functions, and estimati

Fordonens körmönster, dvs hastighets- och accelerationsmönster påverkar mängden utsläpp i hög grad. I tidigare studier har parametern andel kraftig acceleration (a>1,5m/s2) visat sig ha en signifikant effekt framför allt för avgasutsläpp av NOx och HC men även för bränsleförbrukningen. Ett förarstöd som styr accelerationen kan därmed ha en positiv effekt för att minska emissioner och bränsleförbru

A flow-through microdispenser has been coupled to a micro HPLC separation system and used as a solvent elimination interface for Fourier transform infrared (FTIR) and Raman spectroscopic detection of the separated compounds. Using the microdispenser picoliter sized droplets can be generated and deposited on an appropriate target placed on a computerized x, y-stage. Evaporation of volatile solvent

Human blood group antigens are unique, inherited polymorphisms on the extracellular surface of red blood cells. They have been used as genetically discrete markers of human polymorphism since the discovery of the ABO system in 1900. Since then, many blood group antigens have been identified, the genes cloned, and their biological significance elucidated. Blood group antigens and antibodies play an

PURPOSE: To determine whether there is any involvement of sympathetic nerves in the regulation of ocular hyaluronan production in the normal and traumatized rabbit iris. METHODS: Unilateral sympathetic denervation was performed by removing the right superior cervical ganglion. Hyaluronan concentrations in the iris and aqueous were measured with a radiometric assay at various time intervals after d

The aims of this study were: (i) to assess the test-retest intrarater reliability of eccentric ankle dorsiflexor muscle performance in young healthy men and women using the Biodex dynamometer; and (ii) to examine different statistical indices for the interpretation of reliability. Thirty men and women (age 22.5 +/- 2.5 years, mean +/- S.D.) performed three maximal eccentric contractions at 30 degr

Popular Abstract in Swedish Inför hjärtkirurgi är bedömning av en patients individuella nytta av och risk vid en hjärtoperation en viktig komponent i utredningen inför operationen. En riskstratifiering innebär att patientens olika riskfaktorer (exempelvis sockersjuka, högt blodtryck, antal tidigare hjärtinfarkter, hjärtfunktion) vägs samman till en sannolikhets-bedömning av risken för en viss händThe aims of this research was to compare different risk score algorithms with regard to their validity to predict 30-day and one-year mortality after open-heart surgery, to evaluate if the preoperative risk stratification model EuroSCORE predicts the different components of resource utilization in cardiac surgery, and to systematically evaluate the accuracy and performance of artificial neural net

A fission fragment accelerator combined with the Munich high-flux reactor FRM-II is under design for the delivery of intense beams of mass separated very neutron-rich fission fragments with energies at the Coulomb barrier They can be used to produce very heavy neutron-rich nuclei in fusion reactions. The large neutron excess will result in much longer lifetimes of the produced heavy elements, comp

Popular Abstract in Swedish Hörselskadade elever i Jordanien - en studie av faktorer som påverkar elevernas skol- och fritidsaktiviteter. Det övergripande syftet med studien är att beskriva och analysera faktorer som påverkar hörselskadade elevers skol- och fritidsaktiviteter. För att uppnå syftet konstruerades enkäter som distribuerades till hörselskadade elever, deras lärare och föräldrar. FakThe main aim of this study is to describe and analyse the factors affecting the daily life activities of hearing-impaired students in Jordan from the point of view of hearing-impaired students, their teachers, and their parents. Two questionnaires were developed, one directed towards the activities, and the other to the factors affecting these activities. The two questionnaires were distributed am

Cells from the human teratocarcinoma line NTera-2 can be induced to terminally differentiate into postmitotic neurons when treated with retinoic acid. However, this differentiation process is rather time consuming as it takes between 42 and 54 days. Here, we propose a modified differentiation protocol which reduces the time needed for differentiation considerably without compromising the quantity

We discuss the stochastic dynamics of biological (and other) populations presenting a limit behaviour for large environments (called deterministic limit) and its relation with the dynamics in the limit. The discussion is circumscribed to linearly stable fixed points of the deterministic dynamics, and it is shown that the cases of extinction and non-extinction equilibriums present different feature

This work presents an integrated analytical system based on immobilized engineered microorganisms and bioluminescence measurements for monitoring of bioavailable heavy metal ions (Cu being chosen as a model ion). A strain of microorganisms from Alcaligenes eutrophus (AE1239) was genetically engineered by inserting a luxCDABE operon from Vibrio fischeri under the control of a copper-induced promote
