We address the problem of rate adaptation at the Source, given a congested packet based voice carrying network. We propose and analyze a novel method for perceptually based frame discarding. Thus, we propose a Perceptually Based Classifier (PBC) to do the discarding and we combine the PBC with a method for state synchronization, which exploits the knowledge of frame discards to combat the error pr

Recent magnetic-resonance work on Y-Z suggests that this species exhibits considerable motional flexibility in its functional site and that its phenol oxygen is not involved in a well-ordered hydrogen-bond interaction (Tang et al., submitted; Tommos et al., in press). Both of these observations are inconsistent with a simple electron-transfer function for this radical in photosynthetic water oxida

Transplantation of progenitor cells to the CNS has shown promise in neuronal and glial replacement and as a means of rescuing host neurons from apoptosis. Here we examined the effect of progenitor grafts on neurite extension in the degenerating retina of rd1 ( retinal degeneration 1) mice. Transplantation of retinal progenitor cells induced increased matrix metalloproteinase-2( MMP2) secretion, pa

Human preferences are likely to depend on such things as knowledge and information, propaganda and advertising, and formal (laws) and informal (norms) institutions. We focus on knowledge about how nature works and how this may be manifested in recognition of ecosystem services among the general public. Participants and non-participants in a plant nutrient abatement programme with detention ponds i

The BCR gene is implicated in the development of Ph-positive leukemia through its fusion with the nonreceptor tyrosine kinase gene ABL. The normal 160 kDa Bcr protein has several functional domains, and recently one specific role for Bcr was established in the regulation of respiratory burst activity in white blood cells. Bcr expression levels are relatively constant throughout mouse development u

Complement deficiencies are probably vastly under-diagnosed within clinical medicine. Judging from a Swedish study of C2 deficiency, a deficiency with an estimated prevalence of about 1/20,000 in Western countries, less than 10% of the deficiencies of the classical and alternative pathways and the late complement components are identified in Sweden. C1 inhibitor deficiency and deficiencies of MBL

Slave Morality: Theological Perspectives on the Law of Moses. The fusion between the regulations for human relations and behavior on the one hand and worship of and belief in YHWH on the other is the most prominent feature of Biblical Law. The historical background and growth of this characteristic is here investigated and some of its theological implications are scrutinized. Beginning with the la

The purpose of this work is to propose a detailed model for the formation of soot in turbulent reacting flow and to use this model to study a carbon black furnace. The model is based on a combination of a detailed reaction mechanism to calculate the gas phase chemistry, a detailed kinetic soot model based on the method of moments, and the joint composition probability density function (PDF) of the

We recently established that fibroblast growth factor (FGF)-1 promotes adipogenesis of primary human preadipocytes (phPA). In the current report, we have characterized the adipogenic effects of FGF-1 in phPA and also in a human PA strain derived from an individual with Simpson-Golabi-Behmel syndrome (SGBS PA), which exhibit an intrinsic capacity to differentiate with high efficiency. In further st

The distribution of 50 species in the south Swedish provinces of Skane (Scania). Halland, Blekinge, Oland and Smaland has been mapped. Many of the species are endemic to southern Scandinavia and some are local endemics within the investigated area. However, there are also several species with a wider North European distribution. Within the area, the number of species shows a regular decline from t

With the introduction of mammographic screening the incidence of ductal carcinoma in situ (DCIS) has increased to 10-15% of all breast cancers. The aim of this study was to investigate whether there were any morphological and cell biological differences between DCIS detected during the pre-screening (n = 39) as opposed to the screening period (n = 120). We could not demonstrate any statistically s
