Identification of stage-specific surface markers in early B cell development provides novel tools for identification of progenitor populations

Whereas the characterization of B lymphoid progenitors has been facilitated by the identification of lineage-and stage-specific surface markers, the continued identification of differentially expressed proteins increases our capacity to explore normal and malignant B cell development. To identify novel surface markers with stage-specific expression patterns, we explored the reactivity of CD19+ B c

Neurite density imaging versus imaging of microscopic anisotropy in diffusion MRI : A model comparison using spherical tensor encoding

In diffusion MRI (dMRI), microscopic diffusion anisotropy can be obscured by orientation dispersion. Separation of these properties is of high importance, since it could allow dMRI to non-invasively probe elongated structures such as neurites (axons and dendrites). However, conventional dMRI, based on single diffusion encoding (SDE), entangles microscopic anisotropy and orientation dispersion with

Den offentliga ekonomen : En svårbestämd multikonstnär

Under de senaste tjugo åren har offentlig sektor blivit alltmer präglad av New Public Management (NPM). Såväl beskrivningar som konkretiseringar av NPM varierar men två drag återkommer som gemensam nämnare; dels att offentlig sektor har närmat sig den privata i sättet att styra och organisera verksamheten, dels att betoningen har skiftat från ansvar för processer till ansvar för resultat.Med resul

Perceptions of the European Union's Fledgling Delegations: More Coherence, More Effectiveness?

The debate surrounding the challenge of improving coherence in European Union (EU) foreign policy is ongoing. EU Delegations (EUDs), operating under the European External Action Service (EEAS) were recently established to provide a focal point for the EU in third countries, providing potential for improving EU coherence. Using the case study of the EUDs, this article adds to theorizations of EU co

An integration strategy for controls and computing systems at a large particle accelerator based research facility

This paper presents a novel approach for the elaboration of an integration strategy for controls and computing systems at large particle accelerator based research facilities. The approach is applied in a specific case study conducted at the world-leading neutron science facility European Spallation Source (ESS). First, an introduction to the term 'integration' in the Systems Engineering literatur

Det motsägelsefulla beslutet : Om kvinnors syn på och erfarenheter av mammografiscreening

Cancer har kommit att bli en av de största folksjukdomarna i den industrialiserade västvärlden och enbart i Sverige insjuknar över 55 000 personer varje år. Det faktum att var tredje person kommer att drabbas av en cancersjukdom någon gång under sin livstid innebär, förutom ett stort mänskligt lidande, att samhället står inför stora folkhälsopolitiska utmaningar att nå medborgarna med sina hälsofr

Predicting bee community responses to land-use changes : Effects of geographic and taxonomic biases

Land-use change and intensification threaten bee populations worldwide, imperilling pollination services. Global models are needed to better characterise, project, and mitigate bees' responses to these human impacts. The available data are, however, geographically and taxonomically unrepresentative; most data are from North America and Western Europe, overrepresenting bumblebees and raising concer

A continuous growth model for plant tissue

Morphogenesis in plants and animals involves large irreversible deformations. In plants, the response of the cell wall material to internal and external forces is determined by its mechanical properties. An appropriate model for plant tissue growth must include key features such as anisotropic and heterogeneous elasticity and cell dependent evaluation of mechanical variables such as turgor pressur

Auxin Acts through MONOPTEROS to Regulate Plant Cell Polarity and Pattern Phyllotaxis

The periodic formation of plant organs such as leaves and flowers gives rise to intricate patterns that have fascinated biologists and mathematicians alike for hundreds of years [1]. The plant hormone auxin plays a central role in establishing these patterns by promoting organ formation at sites where it accumulates due to its polar, cell-to-cell transport [2-6]. Although experimental evidence as

A Model Analysis of Mechanisms for Radial Microtubular Patterns at Root Hair Initiation Sites

Plant cells have two main modes of growth generating anisotropic structures. Diffuse growth where whole cell walls extend in specific directions, guided by anisotropically positioned cellulose fibers, and tip growth, with inhomogeneous addition of new cell wall material at the tip of the structure. Cells are known to regulate these processes via molecular signals and the cytoskeleton. Mechanical s

China’s innovation system : ten years on

In their 2006 article on innovation in China in this journal, Gu and Lundvall pointed to some weaknesses and challenges for China’s growth and they also outlined ideas for policy action to overcome those. In this short note, written in collaboration with Sylvia Schwag Serger, they go back and assess China's social and economic development in the 10 years that followed in the light of their origina

Exploring the Electronic Band Structure of Organometal Halide Perovskite via Photoluminescence Anisotropy of Individual Nanocrystals

Understanding electronic processes in organometal halide perovskites, flourishing photovoltaic, and emitting materials requires unraveling the origin of their electronic transitions. Light polarization studies can provide important information regarding transition dipole moment orientations. Investigating individual methylammonium lead triiodide perovskite nanocrystals enabled us to detect the pol

Everyday Online Participation : Strategies and Practices in a Multi-Platform Media Landscape

This chapter addresses potential political implications of social media by looking into everyday appropriations of the political opportunities offered to active citizens. It presents and analyses data from interviews with 33 Swedish online participating citizens to gain insight into how they work both with separate and in-between (cross) internet applications as part of their political participati

Biocomposite macroporous cryogels as potential carrier scaffolds for bone active agents augmenting bone regeneration

Osteoinduction can be enhanced by combining scaffolds with bone morphogenic protein-2 (BMP-2). However, BMP's are known to also cause bone resorption. This can be controlled using bisphosphonates like zoledronic acid (ZA). In this study, we produced two different scaffolds containing silk-fibroin, chitosan, agarose and hydroxyapatite (HA) with and without bioactive glass. The aims of the study wer

Models of Mechanics and Growth in Developmental Biology: A Computational Morphodinamics approach

Recent evidence has revealed the role of mechanical cues in the development of shapes in organisms. This thesis is an effort to test some of the fundamental hypotheses about the relation between mechanics and patterning in plants. To do this, we develop mechanical models designed to include specific features of plant cell walls. These are heterogeneous stiffness and material anisotropy as well as

Effects of Economic Policy Uncertainty Shocks on the Long-Run US-UK Stock Market Correlation

We use the economic policy uncertainty indices of Baker, Bloom, and Davis (2016) in combination with the mixed data sampling (MIDAS) approach to investigate the US and UK stock market movements. The long-run US-UK stock market correlation depends positively on US economic policy uncertainty shocks. The US long-run stock market volatility depends significantly on the US economic policy uncertainty
