A PtdIns 4-kinase was purified extensively from rat liver exocytotic vesicles. The enzyme had a low Km for ATP, was inhibited by adenosine, and had an apparent molecular mass of 54 kDa, indicating it to be a type II PtdIns-kinase. The activity of the purified enzyme was enhanced several-fold by PtdCho, and to some extent by other phospholipids with basic polar head groups, and was inhibited by Ptd

Many computing systems are constrained by power budgets. While they could temporarily draw more power, doing so creates unsustainable temperatures and unwanted electricity consumption. Developing systems that operate within power budgets is a constrained optimization problem: configuring the components within the system to maximize performance while maintaining sustainable power consumption. This

The homogenization of cubically arranged, homogeneous spherical inclusions in a background material is addressed. This is accomplished by the solution of a local problem in the unit cell. An exact series representation of the effective relative permittivity of the heterogeneous material is derived, and the functional behavior for small radii of the spheres is given. The solution is utilizing the tr

From a historical view point, one of the most striking features in the Caucasian languages is the preservation of archaic linguistic structures, often represented by the active alignment. These languages might have had contact with non-Caucasian languages but the contact-induced changes may not be as obvious as those in other languages in Europe. In this paper, it is argued that the preservation o

This paper presents low power hardware generation, based on a CAL actor language dataflow implementation. The CAL language gives a higher level of abstraction and generate both hardware and software description. The original CAL flow is targeted for hardware-software co-design of complex systems on FPGA. Modifications are done to the original CAL flow to facilitate low power ASIC implementations.

Computationally hard problems, such as operations on n-dimensional maps, are in need of efficient solutions. Cellular Neural Networks have this promise. This paper explores digital realizations of such computational paradigms through the case of real-time image processing. It is shown that a behaviour-based spatial unrolling of the time-critical numerical convergence loop outperforms a classical f

Report on the deserted medieval chapel of Gussnava in Scania, Sweden. The report is part of a never fullfiled plan of publishing short building archaeological reports on all the medieval churches of the two counties Ljunits and Herrestad at Ystad in Scania as part. The investigation was conducted as a part of the research project "The Cultural Landscape during 6000 years in Southern Sweden", also

Abstract in UndeterminedThe purpose of this paper is to report on the development of a methodology and an associatedmeasurement instrument for diagnosing innovation excellence, and to show how this methodology wasapplied in a case study. The conceptual model behind the measurement instrument has been developedbased on the specific enabler criteria and criteria parts from the European Excellence Mo
