Protein interactions are important in understanding various protein relevant cellular and technological processes.This is a challenging task due to the intrinsically irregular shape and inhomogeneous surface distribution of neutral, charged, hydrophobic amino acid residues. This results inmore or less anisotropic interactions depending on external parameters such assalt and pH. However, a deeper uProtein interactions are important in understanding various protein relevant cellular and technological processes.This is a challenging task due to the intrinsically irregular shape and inhomogeneous surface distribution of neutral, charged, hydrophobic amino acid residues.

Introduction: It has previously been found that strongly predicted words can be pre-activated in constraining contexts (e.g. DeLong, Urbach & Kutas, 2005). Furthermore, it has been suggested that an anticipated continuation from one syllable to another can be pre-activated before it is present in the input (Roll, Söderström, Mannfolk, Shtyrov, Johansson, van Westen & Horne, 2015). We descr

The literature in the Strategic Entrepreneurship (SE) is increasingly embracingthe concept and implications of knowledge spillovers. In this paper, we add to thetheoretical repertoire on SE and knowledge spillovers by investigating the types ofknowledge spillovers and what they imply for various dimensions of SE. On the one hand,we distinguish between spatial and aspatial knowledge spillovers. On

Purpose - The aim of this paper is to explore the implementation of self-service at public libraries from the perspective of their users. The implementation of self-service is related to a diverse societal context including for example an overall digitalisation, budget constraints and political expectations on public libraries to contribute to marketing the local community.Methodology - Semi-struc

Introduction. We present qualitative questionnaires, originally an ethnological method for documenting and collecting material about everyday life, as a fruitful method for information studies. Method. Since the early 20th century qualitative questionnaires, on various themes, have been sent out to informants. The answers to qualitative questionnaires consist of memories, opinions and experiences.

Power consumption is an important design parameter for battery operated devices, and an especially sensitive issue in embedded Java systems. This paper presents a solution to reduce leakage power consumption of the heap memory characteristic of Java processors. By partitioning the heap into several memory banks and taking advantage of a compacting garbage collector, our method dynamically powers o

Today’s multimedia and DSP applications impose requirements on performance and power consumption that only custom processor architectures with SIMD capabilities can satisfy. However, the specific features of such architectures, including vector operations and high-bandwidth complex memory organization, make them notoriously complicated and time consuming to program. In this paper we present an aut

We investigate antenna correlation of an M-antenna massive multiple-input multiple-output (MIMO) setup with the purpose of obtaining a low-rank representation of the instantaneous massive MIMO channel. Low-rank representation bases using short-term and long-term antenna correlation statistics are defined, and their performance is evaluated with data sets obtained from channel measurements in both

Coordinated Multi Point (CoMP) transmission and reception techniques are used in order to improve the performance of single or multiple cells in wireless systems. A system using CoMP techniques is capable of jointly optimizing its transmission and/or reception and, hence, achieving higher performance. In this work, performance evaluation of three CoMP techniques are performed based on simulations

In this paper, the effect of polarization on the downlink sum-rate capacity of multi-user Cooperative Multi-Point (CoMP) systems using synchronous multi-link measurement data, for two different antenna arrangements, is studied. In the first setup, four antenna patches each of which with dual-polarized antenna elements at the base station (BS) with inter-patch distance varied from half wavelength tIn this paper, the effect of polarization on the downlink achievable sum-rate of multi-user Cooperative Multi-Point (CoMP) systems is studied using synchronous multi-link channel measurements with two different antenna arrangements. In the first setup, four dual-polarized antenna patches with inter-patch distance varied from half wavelength to 8 m are considered at the base station (BS). In the se

The possibility of using radio over fiber (RoF) analog transmissions to characterize the wireless propagation channel of distributed antenna systems is investigated. In particular, the coherence time of kilometer-long, fiber-based networks is analyzed. Joint measurements of the phase noise of parallel links to the same site (intra-site) and to different sites (inter-site) in such a network are pre

This paper presents an approach to the synthesis of low-power fault-tolerant hard real-time applications mapped on distributed heterogeneous embedded systems. Our synthesis approach decides the mapping of tasks to processing elements, as well as the voltage and frequency levels for executing each task, such that transient faults are tolerated, the timing constraints of the application are satisfie
