One of the most important technical problems in reliable multicast protocol is reducing redundant NAKs to avoid NAK implosion. A number of NAK suppression mechanisms have been proposed to deal with this problem. In the MBONE, which is a virtual multicast network and makes multi-point communication across the Internet feasible, the source link, the links directly connected to or very close to th...
The Feldspar project aims to develop a domain specific language for Digital Signal Processing algorithm design. From functional descriptions, imperative code (currently C) is generated. The project partners are Ericsson, Chalmers and ELTE, Budapest. The background and motivation for the project have been documented elsewhere [3]. We aim to raise the level of abstraction at which algorithm devel...
The Nef protein of primate immunodeficiency viruses plays an important role in the pathogenesis of acquired immunodeficiency syndrome (AIDS) [1] [2]. The interaction of Nef with the Nef-associated kinase (NAK) is one of the most conserved properties of different human and simian immunodeficiency virus (HIV and SIV) Nef alleles. The role of NAK association is currently not known but it has been ...
We have recently identified the Nef-associated serine-threonine kinase (NAK) as the p21-activated kinase 2 (PAK2). Here we have taken advantage of the possibility to manipulate the functional properties of NAK by transfecting PAK2 cDNA or its mutant derivatives in order to further characterize the Nef-NAK complex. To exclude the possibility that some Nef variants might interact with PAK1 instea...
The effects of thyroid hormone on guinea pig myocardial NaK-ATPase activity, transmembrane monovalent cation active transport, and cardiac glycoside binding were were examined. NaK-ATPase activities of left atrial and left ventricular homogenates of control and triiodothyronine (T3)-treated animals were determined, and compared to activities of skeletal muscle and liver. T3 administration was a...
OBJECTIVE Alkali metal appears to be a promising tool in thermochemical ablation, but, it requires additional data on safety is required. The objective of this study was to explore the effectiveness of permeable oil-packed liquid alkali metal in the thermochemical ablation of tumors. METHODS Permeable oil-packed sodium-potassium (NaK) was prepared using ultrasonic mixing of different ratios o...
The internal layering and provenance of feldspar in 3 tills and in one outwash deposit at Gahanna, Ohio, were studied by determining pebble lithologies and Rb-Sr dates of feldspar. Variations in lithology of pebbles and in the Rb-Sr ratios of feldspar in the 125—250 micrometer fractions reveal discontinuities which divide the upper 2 tills into 2 subunits each. Each of the lower subunits appear...
INTRODUCTION Flexure of a dental composite can be detrimental to the success of a restoration. Flexibility considerations are thus important when comparing dental materials to optimize the success of resin restorations. AIMS AND OBJECTIVES Flexibility of 5.6 x 18.0 x 2.0 mm3 experimental alumina/feldspar and SR ADORO dental composites specimens were compared. It was hypothesized that alumina/...
Flux-dependent inactivation that arises from functional coupling between the inner gate and the selectivity filter is widespread in ion channels. The structural basis of this coupling has only been well characterized in KcsA. Here we present NMR data demonstrating structural and dynamic coupling between the selectivity filter and intracellular constriction point in the bacterial nonselective ca...
