Four distinct trajectories of tau deposition identified in Alzheimer’s disease

Alzheimer’s disease (AD) is characterized by the spread of tau pathology throughout the cerebral cortex. This spreading pattern was thought to be fairly consistent across individuals, although recent work has demonstrated substantial variability in the population with AD. Using tau-positron emission tomography scans from 1,612 individuals, we identified 4 distinct spatiotemporal trajectories of ta

Multidimensional Incongruence, Political Disaffection, and Support for Anti-Establishment Parties

To what extent do representational gaps between parties and voters destabilise party systems and create electoral opportunities for anti-establishment parties on the left and right? In this paper, we use multiple measures of party-partisan incongruence to evaluate whether issue-level incongruence contributes to an increase of political disaffection and anti-establishment politics. For this analysi

Radiofrequency bias correction of magnetization prepared rapid gradient echo MRI at 7.0 Tesla using an external reference in a sequential protocol

At field strengths of 7 T and above, T1-weighted imaging of human brain suffers increasingly from radiofrequency (RF) B1 inhomogeneities. The well-known MP2RAGE (magnetization prepared two rapid acquisition gradient echoes) sequence provides a solution but may not be readily available for all MR systems. Here, we describe the implementation and evaluation of a sequential protocol to obtain normali

Analyzing the Cross-National Comparability of Party Positions on the Socio-Cultural and EU dimensions in Europe

Using survey vignettes and scaling techniques, we estimate common socio-cultural and European integration dimensions for political parties across the member states of the European Union. Previous research shows that party placements on the economic left-right dimension are cross-nationally comparable across the EU; however, the socio-cultural dimension is more complex, with different issues formin

Developing shared languages : The fundamentals of mutual learning and problem solving in transdisciplinary collaboration

This issue of the AILA Review focuses on transdisciplinarity as the key to developing shared languages in and across domains and professional settings. The relationship and collaboration between researchers and practitioners have long been discussed within and across applied sciences and theoretical disciplines, mainly in the framework of transdisciplinarity (see AILA Review 31, 2018, for a recent

Party Responsiveness to Public Opinion in Young Democracies

Are political parties in young democracies responsive to the policy preferences of the public? Compared to extensive scholarship on party responsiveness in established democracies, research on party responsiveness in young democracies is limited. We argue that weaker programmatic party–voter linkages in post-communist democracies create incentives for parties to respond to their supporters rather

Assessing the potential and hydrological usefulness of the CHIRPS precipitation dataset over a complex topography in Pakistan

This study evaluates the spatial and temporal performance of the Climate Hazard Group InfraRed Precipitation Satellite (CHIRPS) against Tropical Rainfall Measuring Mission (TRMM) Multi-Satellite Precipitation Analysis (TMPA) 3B42/3B43 v. 7 and Global Precipitation Measurement (GPM)-based Integrated Multi-Satellite Retrievals for GPM (IMERG V06), from 2000 to 2013. Several statistical metrics were

Congruence and Party Responsiveness in Western Europe in the 21st Century

Research on party responsiveness in established democracies suggests that parties follow shifts in the preferences of either the general electorate or party supporters. Drawing on theoretical models of party competition and research on party-voter congruence, we argue in this article that in the 21st century Western European mainstream parties respond to their partisan constituents. Parties adjust

Hypothermia versus normothermia after out-of-hospital cardiac arrest

BACKGROUND Targeted temperature management is recommended for patients after cardiac arrest, but the supporting evidence is of low certainty. METHODS In an open-label trial with blinded assessment of outcomes, we randomly assigned 1900 adults with coma who had had an out-of-hospital cardiac arrest of presumed cardiac or unknown cause to undergo targeted hypothermia at 33°C, followed by controlled

Shrub-dwelling species are joining the Arctic passerine bird community in the Chaun Delta (Western Chukotka, Russia)

Avian communities play a pivotal role in Arctic ecosystems and birds have become the key model taxa for climate change research. Due to funding priorities, Arctic passerines have been studied less intensively than waterfowl and shorebirds. In our study, we aim to partly fill this gap and look at the change in passerine community species composition in the Chaun River Delta in Northeast Siberia (68

A Clash of Sexual Gender Norms and Understandings : A Qualitative Study of Homosexual, Bisexual, Transgender, and Queer Adolescents’ Experiences in Junior High Schools

The objective of this study is to explore the inclusiveness of lesbian, gay, bisexual, transgender, and queer (LGBTQ) adolescents in junior high school from the perspective of LGBTQ adolescents in Sweden. Semi-structured in-depth interviews were conducted with 10 GBTQ adolescents, aged 16 to 19. The study was approved by the Swedish Ethical Review Authority (Dnr: 2019-03816). A Braun and Clark ins

Outcome after acute ischemic stroke is linked to sex-specific lesion patterns

Acute ischemic stroke affects men and women differently. In particular, women are often reported to experience higher acute stroke severity than men. We derived a low-dimensional representation of anatomical stroke lesions and designed a Bayesian hierarchical modeling framework tailored to estimate possible sex differences in lesion patterns linked to acute stroke severity (National Institute of H

Intergenerational care in corona times: Practices of care in Swedish families during the pandemic

Objective: This paper analyses intergenerational relationships in Sweden during the corona pandemic, with a special focus on practices of care. The research question is: How is care between generations – between grandparents, adult children and grandchildren – done during pandemic conditions? Background: In Sweden, where an extensive welfare state provides affordable child- and eldercare, the coro

RIFM fragrance ingredient safety assessment, 4,8-decadienal, (4Z,8Z)-, CAS Registry Number 1958027-35-4

Summary: The existing information supports the use of this material as described in this safety assessment. 4,8-Decadienal, (4Z,8Z)- was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analogs 4,7-decadienal (CAS # 934534-30-2) and nona-2-tran

Trade-Offs in Decentralized Multi-Antenna Architectures: The WAX Decomposition

Current research on multi-antenna architectures is trending towards increasing the amount of antennas in the base stations (BSs) so as to increase the spectral efficiency. As a result, the interconnection bandwidth and computational complexity required to process the data using centralized architectures is becoming prohibitively high. Decentralized architectures can reduce these requirements by pr

Measurement of the very rare K+→π+νν- decay

The NA62 experiment reports the branching ratio measurement BR(K+→π+νν¯)=(10.6−3.4+4.0|stat±0.9syst)×10−11 at 68% CL, based on the observation of 20 signal candidates with an expected background of 7.0 events from the total data sample collected at the CERN SPS during 2016–2018. This provides evidence for the very rare K+→π+νν¯ decay, observed with a significance of 3.4σ. The experiment achieves a
