During surfactant treatment of respiratory distress syndrome, 23 premature newborns were investigated with continuous amplitude-integrated electroencephalography (cerebral function monitors). Simultaneously, arterial blood pressure and transcutaneous blood gas values were recorded. A short (less than 10 minutes) but significant decrease in cerebral activity was seen in almost all neonates immediat

The basic underlying mechanisms behind atrial fibrillation (AF), the most abundant therapy demanding cardiac dysrhythmia, have until recently being largely unknown. Once established, AF is not only self-perpetuating but also self-destructive, prompting rapid treatment against possible initiating mechanisms. Recent observations reveal that the ectopic beats, initiating AF, often originate in the wa

Background. Early enteral nutrition with solutions containing prebiotics (fiber) and probiotics (Lactobacillus) is suggested to reduce bacterial translocation and minimize the incidence of infections after liver transplantation. Methods. In a prospective, randomized placebo-controlled trial consisting of 95 patients, we compared the incidence of postoperative infections and other complications aft

The topic of low computational complexity frequency estimation of a single complex sinusoid corrupted by additive white Gaussian noise has received significant attention over the last decades due to the wide applicability of such estimators in a variety of fields. In this letter, we propose a computationally fast and statistically improved hybrid phase-based estimator that outperforms other recent

Selective lifetime measurements by time-resolved laser-induced fluorescence spectroscopy for 5 levels belonging to the 4f(3)5d configuration of doubly ionized neodymium provide a first and useful experimental test of the relativistic Hartree-Fock calculations in this ion of astrophysical interest. As a consequence, the accuracy of the transition probabilities deduced in the present work is well as

The ISO standard tapping machine, used as an excitation source in rating the impact-sound level of a floor structure, interacts with the floor structure during the hammer impact. Expressions for the force spectrum due to the impact are presented. The 6 dB difference at low frequencies of the force spectrum, evident in measurements, and reasons for it, are discussed. The interaction is investigated

We present a simple model for the arterial part of the cardiovascular system, based on Poiseuille flow constrained by the power dissipated into the cells lining the vessels. This, together with the assumption of a volume-filling network, leads to correct predictions for the evolution of vessel radii, vessel lengths and blood pressure in the human arterial system. The model can also be used to find

eta(c)(2980) production in gammagamma interactions has been detected via its decays into K(s)(0)K(-/+)pi(-/+), K+K-K+K- and K(+)K(-)pi(+)pi(-) in the data taken with the DELPHI detector at LEP1 and LEP2 energies. The two-photon radiative width averaged over all observed decay channels is Gammagammagamma=13.9+/-2.0(stat.)+/-1.4(syst.)+/-2.7 (BR) keV. No direct decay channel eta(c)-->pi(+)pi(-)pi(+)

We have analyzed the M-bcr breakpoint position in 133 Philadelphia-positive chronic myeloid leukemia patients and correlated the findings with clinical, hematologic, and cytogenetic data. We also investigated the splicing pattern of the BCR-ABL mRNA in 30 patients, using reverse transcriptase PCR. No statistically significant differences were found between breakpoint position within M-bcr and clin

An on-chip clock for frequencies up to 190 MHz is presented. This clock generator can be used for application specific digital signal processors which are clocked faster than the off-chip system clock. It is useful for both processors with a few cycles per sample or for high frequency bit-serial processors which need a large number of cycles

Aim This paper presents a probabilistic method of pollen spectra analysis. The method relies on a pollen taxon characterization using biotic and abiotic plant attribute modes, and their occurrence in a given pollen spectrum at a specific site. This type of analysis can provide an interpretation, which can lead to the reconstruction of the biome and, to an extent, of the abiotic conditions at the s

The article examines different attempts to analyse the Christian men's movement, Promise Keepers, and the fatherhood responsibility movement. Complexity used as an argument to abandon the search for a gender ideology in the movements is criticized. Despite the presence of complex features, for example, regarding Promise Keepers' view on gender roles in the family, there are common assumptions of g
