Functional surface layers in relaxor ferroelectrics

Relaxor ferroelectrics are technologically important materials for applications in, for example, high-temperature capacitors, transducers and nano-positioning systems. These materials have often been reported to exhibit surface or skin layers with distinct physical properties to the bulk. The control of formation and functionality of these skin layers has remained elusive and is becoming increasin

Circulating Levels of Brain-Enriched MicroRNAs Correlate with Neuron Specific Enolase after Cardiac Arrest-A Substudy of the Target Temperature Management Trial

Outcome prognostication after cardiac arrest (CA) is challenging. Current multimodal prediction approaches would benefit from new biomarkers. MicroRNAs constitute a novel class of disease markers and circulating levels of brain-enriched ones have been associated with outcome after CA. To determine whether these levels reflect the extent of brain damage in CA patients, we assessed their correlation

Finnish study of intraoperative irrigation versus drain alone after evacuation of chronic subdural haematoma (FINISH) : a study protocol for a multicentre randomised controlled trial

INTRODUCTION: Chronic subdural haematomas (CSDHs) are one of the most common neurosurgical conditions. The goal of surgery is to alleviate symptoms and minimise the risk of symptomatic recurrences. In the past, reoperation rates as high as 20%-30% were described for CSDH recurrences. However, following the introduction of subdural drainage, reoperation rates dropped to approximately 10%. The stand

Single-single gravitational-wave captures in globular clusters : Eccentric deci-Hertz sources observable by DECIGO and Tian-Qin

We study the formation rate of binary black hole mergers formed through gravitational-wave emission between unbound, single black holes in globular clusters. While the formation of these binaries in very dense systems such as galactic nuclei has been well studied, we show here that this process can operate in lower-density stellar systems as well, forming binaries at a rate similar to other propos

In situ analysis of cast irons mechanical behaviour using synchrotron x-ray tomography and 3DXRD

When subjecting cast irons to mechanical loading the deformation and damage mechanisms occur on a microstructural level and are dependent on the inherent microstructure. A deeper understanding of the relation between the different microstructural constituents and the macroscopic mechanical behaviour would be beneficial in material development efforts and for the ability to design and cast componen

Mobile Formation Coordination and Tracking Control for Multiple Nonholonomic Vehicles

This article addresses forward motion control for trajectory tracking and mobile formation coordination for a group of nonholonomic vehicles on SE(2). First, by constructing an intermediate attitude variable which involves vehicles' position information and desired attitude, the translational and rotational control inputs are designed in two stages to solve the trajectory tracking problem. Second,

Assessing the black box of feedback neglect in a digital educational game for elementary school

Background: Previous research shows that critical constructive feedback, that scaffolds students to improve on tasks, often remains untapped. The paper’s aim is to illuminate at what stages students provided with such feedback drop out of feedback processing. Methods: In our model, students can drop out at any of five stages of feedback processing: (1) noticing, (2) decoding, (3) making sense, (4)

The utopian quest for an alternative

There is no alternative! Margaret Thatcher once proclaimed in order to defend neoliberalist reforms and – implicitly – the capitalist regime. But if one doesn’t agree with Thatcher’s definition of the situation and her (and her many followers’) subsequent analysis, what viable options does one really have? Is it possible to come up with an empirically grounded alternative to the dominant modes of

Compact City Planning and Development : Emerging Practices and Strategies for Achieving the Goals of Sustainable Development

Compact city planning and development has, over the last 30 years or so, been the hegemonic response to the challenges of sustainable development. Global and local policies promote the compact city model due to the positive outcomes of its design principles and strategics as to achieving sustainable cities in terms of their environmental, economic, and social goals. The aim of this paper is to exa

Assembly of Capsids from Hepatitis B Virus Core Protein Progresses through Highly Populated Intermediates in the Presence and Absence of RNA

The genetic material of viruses is protected by protein shells that are assembled from a large number of subunits in a process that is efficient and robust. Many of the mechanistic details underpinning efficient assembly of virus capsids are still unknown. The assembly mechanism of hepatitis B capsids has been intensively researched using a truncated core protein lacking the C-terminal domain resp

Reaching adulthood with Hirschsprung's disease : Patient experiences and recommendations for transitional care

Background/Purpose: The need for transitional care has gained increased focus in the treatment of patients with congenital colorectal disorders. We aimed to acquire in-depth knowledge about the experiences of adult patients with Hirschsprung's disease (HD) and their suggestions for transitional care. Methods: Binational study applying gender equal focus group interviews (FGI). Results: Seventeen (

Per-and polyfluoroalkyl substances in early pregnancy and risk for preeclampsia : A case-control study in southern Sweden

Preeclampsia is one of the most common causes of perinatal and maternal morbidity/ mortality. One suggested environmental risk factor is exposure to endocrine-disrupting pollutants such as per-and polyfluoroalkyl substances (PFAS). The present case-control study in southern Sweden aims to investigate the hypothesized association between serum concentrations of PFAS in early pregnancy and the risk

Detection and attribution of flood responses to precipitation change and urbanization : A case study in Qinhuai River Basin, Southeast China

Both flood magnitude and frequency might change under the changing environment. In this study, a procedure combining statistical methods, flood frequency analysis and attribution analysis was proposed to investigate the response of floods to urbanization and precipitation change in the Qinhuai River Basin, an urbanized basin located in Southeast China, over the period from 1986 to 2013. The Mann–K

Time trends in pediatric fractures in a Swedish city from 1950 to 2016

Background and purpose — As previous studies indicate time trends in pediatric fracture incidence, we followed the incidence in a Swedish city between 1950 and 2016. Patients and methods — Malmö city, Sweden had 322,574 inhabitants in 2015. We used diagnosis registry, charts, and radiographs of the only city hospital to classify fractures in individuals < 16 years in 2014–2016, and compared these

Height, body mass index and prostate cancer risk and mortality by way of detection and cancer risk category

Obesity is a risk factor for advanced, but not localised, prostate cancer (PCa), and for poor prognosis. However, the detection of localised PCa through asymptomatic screening might influence these associations. We investigated height and body mass index (BMI) among 431 902 men in five Swedish cohorts in relation to PCa risk, according to cancer risk category and detection mode, and PCa-specific m

Genetically programmed changes in transcription of the novel progranulin regulator

Abstract: Progranulin is a glycoprotein marking chronic inflammation in obesity and type 2 diabetes. Previous studies suggested PSRC1 (proline and serine rich coiled-coil 1) to be a target of genetic variants associated with serum progranulin levels. We aimed to identify potentially functional variants and characterize their role in regulation of PSRC1. Phylogenetic module complexity analysis (PMC
