Purpose: To implement and evaluate a sequential approach to obtain semi-quantitative T1-weighted MPRAGE images, unbiased by B1 inhomogeneities at 7T.Methods: In the reference gradient echo used for normalization of the MPRAGE image, flipangle (αGE) and acquisition voxel size (Vref) was varied to optimize tissue contrast and acquisition time (Tacq). The finalized protocol was implemented at three d
Background: Magnetization transfer (MT) saturation reflects the additional saturation of the MRI signal imposed by an MT pulse and is largely driven by the saturation of the bound pool. This reduction of the bound polarization by the MT pulse is less efficient than predicted by the differential B1-square law of absorption. Thus, B1 inhomogeneities lead to a residual bias in the MT saturation maps.
This paper proposes a BP-based algorithm for sequential detection and estimation of MPC parameters based on radio signals. Under dynamic channel conditions with moving transmitter and/or receiver, the number of MPCs reflected from visible geometric features, the MPC dispersion parameters (delay, angle, Doppler frequency, etc), and the number of false alarm contributions are unknown and time-varyin
The resistance and resilience provided by functional redundancy, a common feature of microbial communities, is not always advantageous. An example is nitrite oxidation in partial nitritation-anammox (PNA) reactors designed for nitrogen removal in wastewater treatment, where suppression of nitrite oxidizers like Nitrospira is sought. In these ecosystems, biofilms provide microhabitats with oxygen g

In this article, I draw on the experiences of Iraqi diasporas in the UK and Sweden after the 2003 US-led intervention to demonstrate how ethno-sectarianism in Iraq has affected their political transnationalism. Using the concepts of intersectionality and positionality, I show how the reconfiguration of the social positions of individuals and groups in the diaspora affects their types of political
While the literature has expounded diaspora’s involvement in homeland politics through lobbying efforts to influence hostland foreign policies, involvement in homeland conflicts and peace-building, this paper addresses a less-explored area in the diaspora literature related to the development of democracy through transnational civil society building. Using the case study of the Iraqi diaspora in S
How do we explain change in political transnationalism over time? In what way does this change affect diasporic identities? And how does this change alter the relationship and power of diasporic actors towards their homeland states? This paper addresses these questions in relation to Iraqi Shi’a political transnationalism between London and Iraq pre and post-2003. I argue that the confluence of po
This article explores the role of religion in political transnationalism using the case of the Shi'a Iraqi diaspora since 2003. The article focuses on three areas that capture important trends in Shi'a transnationalism and their implications for transnational Shi'a identity politics. These include Shi'a diasporic politics, transnational Shi'a civic activism, and the cultural production of Iraqi Sh
Iraqi diaspora mobilization and the future development of Iraq – authored by Dr. Oula Kadhum, explores Iraqi diaspora mobilization before and after the 2003 invasion and fall of the regime of Saddam Hussein. It looks at the ways members of the diaspora sought to help in the rebuilding of their country of origin, at both the elite and grassroots levels, as well as investigating changes over time. I
During the last decade it has been increasingly acknowledged that carbon (C) contained in root exudates can accelerate decomposition of soil organic matter (SOM), a phenomenon known as rhizosphere priming effect (RPE). However, the controlling factors and the role of different soil microorganisms in RPE are not yet well understood. There are some indications that the response of the soil microbial
Land-cover changes have a clear impact on local climates via biophysical effects. European land cover has been affected by human activities for at least 6000 years, but possibly longer. It is thus highly probable that humans altered climate before the industrial revolution (AD1750–1850). In this study, climate and vegetation 6000 years (6 ka) ago is investigated using one global climate model, two
We present the archaeological discovery and microscale X-ray Computed Tomography (µCT) scanning of a silver coin purse lost in a medieval shipwreck while the king who issued many of the coins was aboard. The find demonstrates that shipwrecks are extraordinary repositories of historical information, in this case providing insight into one of the most important and dramatic events of medieval Scandi
Efter flera krig övergick på 1600-talet Skåne, Halland och Blekinge från Danmark till Sverige, medan Bornholm förblev danskt. Övergången var gradvis, inte utan motstånd, och den varierade mellan och även inom landskapen. Artikeln undersöker hur dansk och svensk överhöghet synliggjordes i kyrkorna under denna övergångstid med bilder på riksvapnet, kungliga namn och monogram, särskilt på altaruppsat
