The Kauffman model describes a particularly simple class of random Boolean networks. Despite the simplicity of the model, it exhibits complex behavior and has been suggested as a model for real world network problems. This work is based on an earlier paper where we introduced a novel approach to analyzing attractors in random Boolean networks. Applying this approach to Kauffman networks, we prove
It is important to understand the relative contribution of primary and secondary particles to regional and global aerosol so that models can attribute aerosol radiative forcing to different sources. In large-scale models, there is considerable uncertainty associated with treatments of particle formation (nucleation) in the boundary layer (BL) and in the size distribution of emitted primary particl
Abstract Background: Eleven years ago we had described three patients with missing nexin links as a possible cause of primary ciliary dyskinesia (PCD). The assumption was substantiated last year by finding a mutation in these patients. Materials and Methods: We counted the nexin links, inner (IDA) and outer (ODA) dynein arms and microtubuli in each of, if possible, 50 cilia in 41 patients with nor
Objectives: Our aim was to elicit data representative of normal findings on 3-dimensional (3D) transvaginal gray-scale and power Doppler sonography of ovaries in women of fertile age. Methods: A total of 303 gynecologically asymptomatic white women 20 to 39 years old with spontaneous regular menstrual cycles were examined with transvaginal 3D gray-scale and power Doppler sonography on cycle days
Components that have defects after release, but not during testing, are very undesirable as they point to 'holes' in the testing process. Either new components were not tested enough, or old ones were broken during enhancements and defects slipped through testing undetected. The latter is particularly pernicious, since customers are less forgiving when existing functionality is no longer working t
It is has been suggested that decreased production of the vasodilatory and anti-aggregative substance NO (nitric oxide) may result in lower cerebral blood flow (CBF) in injured areas of the traumatized brain. The NO-precursor L-arginine has been shown to counteract CBF decreases early after trauma, but microcirculatory and more long-term effects on CBF of L-arginine have not been investigated. In
The effect of long-term ethanol exposure on muscarinic receptors was investigated in human neuroblastoma SH-SY5Y cells. Exposure to 100 mM ethanol for 4 days enhanced both peak and steady-state levels of carbachol-stimulated inositol 1,4,5-bisphosphate increase. An ethanol concentration of 50 mM was sufficient for an enhancement of this event. The carbachol-stimulated decrease in [3H]inositol-labe
Ovarian cancer, often called the silent killer due to its diffuse symptoms at early stage, poor prognosis after treatments and high mortality, is also a heterogeneous disease consisting of different histological subtypes with potentially different origins. About 90% of all cases derive from epithelial cells and high-grade serous ovarian carcinoma (HGSOC) is the most common and aggressive form of e
The streaming instability provides an efficient way of overcoming the growth barriers in the initial stages of the planet formation process. Considering the realistic case of a particle size distribution, the dynamics of the system is altered compared to the outcome of single size models. In order to understand the outcome of the multispecies streaming instability in detail, we perform a large par
