Many cells express receptors for plasminogen (Pg), although the responsible molecules in most cases are poorly defined. In contrast, the group A streptococcal surface protein PAM contains a domain with two 13-amino acid residue long repeated sequences (a1 and a2) responsible for Pg binding. Here we identify the region in Pg that interacts with PAM. A radiolabeled proteolytic plasminogen fragment c

Innovation has been regarded a crucial means by which organizations adapt to the changes in the environment. Previous studies have identified organizational culture as a key factor that influences innovation, suggesting that a culture with certain characteristics can lead to superior innovation performance. This culture is referred to as “innovation culture”, a notion which has recently enjoyed gr

The process of selecting requirements for a release of a software product is challenging as the decision-making is based on uncertain predictions of issues such as market value and development cost. This paper presents a method aimed at supporting software product development organisations in the identification of process improvement proposals to increase requirements selection quality. The method

In this paper, an efficient technique to enhance the isolation between two closely spaced PIFAs for MIMO mobile terminals is introduced. The proposed decoupling method is based on a T-shape slot impedance transformer and it enables an inter-PIFA spacing of 1 mm to be achieved. The 10 dB impedance bandwidth and 20 dB isolation bandwidth cover the 2.4 GHz WLAN band (2.4-2.48 GHz), with a maximum iso

In search of more environmentally friendly polymer materials, polyhydroxyalkanoates (PHAs) have been considered as promising candidates. PHAs exhibit a broad range of material properties, can be produced from renewable resources and are completely biodegradable. Nevertheless, high production costs associated with traditional PHA production based on fermentation by pure microbial cultures have so f

Jag får ofta frågan om den här övervakningshysterin som diskuterats högt och ljudligt senaste tiden faktiskt berör gemene man. Det är en bra fråga. Svaret är att det är oklart. Hela övervakningsfrågan är en balansgång mellan sådant som effektivitet i brottsbekämpning och allas vår personliga integritet.

This paper stems from an inductive research problem: the support given to the military-deep state by the youth revolutionary movement in Egypt’s political upheavals of summer 2013. Why would the youth revolutionary movement choose to support the military-deep state’s political maneuverings, and what is the precise nature of this support? To answer these questions, this paper chooses to explore two

In this paper we consider control signal properties, such as maximum magnitude and activity, as well as system robustness measures. We derive an ideal controller and control signal for exponential disturbance rejection for a first order process with time delay. For the resulting closed-loop system, it is shown analytically that there are strong interconnections between robustness measures and cont

In this paper propagation of transient electromagnetic waves in a reciprocal bi-isotropic medium is presented. The constitutive relations are convolution integrals with two susceptibility kernels that model the medium. The propagation problem is solved by the introduction of a wave-splitting technique. This wave-splitting is used to solve the propagation problem using either an imbedding approach
