Reducing bias in dual flip angle T1-mapping in human brain at 7T

Purpose: To address the systematic bias in whole-brain dual flip angle (DFA) T1-mapping at7T by optimizing the flip angle pair and carefully selecting RF pulse shape and duration.Theory and Methods: Spoiled gradient echoes can be used to estimate whole-brain maps ofT1. This can be accomplished by using only two acquisitions with different flip angles, i.e., aDFA-based approach.

Auralization as a tool of historic reconstruction of Vadstena Abbey church

Throughout human history, there have been locations used for performance of speech and music. Many of these locations are considered part of our common cultural heritage, and more and more of them can be visited virtually as technology advances to produce better and better reconstructions. However, the technological capabilities are not the only limitations when it comes to historical reconstructi

Diffusers in public ordinary rooms

Traditionally, the room acoustic properties in an ordinary public room are defined by only one parameter, the reverberation time. However, research has showed that additional room acoustic parameters as sound strength and speech clarity are necessary to consider in order to achieve good acoustic conditions. In a room with acoustical ceiling treatment the effects of furniture and interiors on the r

Between 'Everyday' and 'Extraordinary' : Partition, violence and the communal riots of 1946 in Bihar

The year 1937 saw the establishment of Congress Ministries in eight of the eleven provinces in which the provincial elections had been held, Bihar being one of them. The resounding victory of the Congress which secured a clear majority in the province of Bihar and the dismal performance of the Muslim League seemed at the time to depict the mood of the people in general. It was taken as a clear rej

Plasma receptor tyrosine kinase RET in pulmonary arterial hypertension diagnosis and differentiation

Background: Pulmonary arterial hypertension (PAH) is a serious disease exhibiting unspecific symptoms, as a result of which diagnosis is often delayed and prognosis is poor. The underlying pathophysiology includes vasoconstriction and remodelling of small pulmonary arteries. As receptor tyrosine kinases (RTKs) and their ligands have been shown to promote PAH remodelling, our aim was to evaluate if

In-hospital cardiac arrest and preceding National Early Warning Score (NEWS) : A retrospective case-control study

We aimed to describe and evaluate the National Early Warning Score (NEWS) in the 24 hours preceding an in-hospital cardiac arrest among general somatic ward patients.The 24 hours preceding the in-hospital cardiac arrest were divided into four timespans and analysed by a medical record review of 127:254 matched case-control patients. The median NEWS ranged from 3 (2-6) to 6 (3-9) points for cases v

National Early Warning Score (NEWS) : A survey of registered nurses´ perceptions, experiences and barriers

AIMS & OBJECTIVES: Describe Registered Nurses (RN) perceptions and experiences of and barriers for using the National Early Warning Score (NEWS) in relation to their work experience and medical affiliation.BACKGROUND: Indications of inconsistencies in adherence to the NEWS has emerged.DESIGN: Web-based questionnaire study.METHODS: The questionnaire was sent to 3,165 RNs working in somatic hosp

Withholding or withdrawing of life-sustaining therapy in older adults (≥ 80 years) admitted to the intensive care unit

PURPOSE: To document and analyse the decision to withhold or withdraw life-sustaining treatment (LST) in a population of very old patients admitted to the ICU.METHODS: This prospective study included intensive care patients aged ≥ 80 years in 309 ICUs from 21 European countries with 30-day mortality follow-up.RESULTS: LST limitation was identified in 1356/5021 (27.2%) of patients: 15% had a withho

The first structure of an active mammalian dCTPase and its complexes with substrate analogues and products

Precise regulation of dNTPs within the cellular nucleotide pool is essential for high accuracy of DNA replication and is critical for retaining the genomic integrity. Recently, human dCTPase (deoxycytidine triphosphatase), also known as DCTPP1 (human all-alpha dCTP pyrophosphatase 1) has been revealed to be a key player in the balance of pyrimidine nucleotide concentrations within cells, with DCTP

Disappearing investment‐cash flow sensitivities: earnings have not become a worse proxy for cash flow

According to a recent conjecture in the literature, earnings have become a poorer proxy for cash flow from operations over time. We find that since 1988, when cash flow statements started to be consistently reported in Compustat, the cash effectiveness of earnings has actually increased for a large sample of U.S. manufacturing firms. This occurs despite the introduction of fair value accounting an

One-dimensional full-range mixture fraction measurements with femtosecond laser-induced plasma spectroscopy

Abstract: Femtosecond laser-induced plasma spectroscopy (FLIPS) was performed to achieve full-range mixture fraction measurements in non-reacting CH4/air flow fields. A femtosecond laser at 800 nm was used to generate a plasma channel with a uniform intensity distribution. Through measuring spatially resolved spectra and calibration, we found that the spectral intensity ratios of CH (431 nm)/N2 (3

Trends in the Study of Modern languages in Swedish Lower Secondary School (2000 – 2018) and the Impact of Grade Point Average Enhancement Credits

This paper investigates trends in the study of Modern languages or second foreign languages (SFLs) in Swedish lower secondary school between 2000 and 2018. Over the last decades, SFLs, i.e. French, German and Spanish, have been the target of several policy measures as a response to a declining interest. However, few reports on their impact have been published. We report the proportion of pupils st

AnthropoScenes : A climate fiction competition

In 2019, the Climaginaries project ran a climate fiction competition. Out of more than 40 entries, five winners were selected and published in this collection. More of the entries can be found on climaginaries.org/anthroposcenes.

Trajectory optimization of an oscillating industrial two-stage evaporator utilizing a Python-Aspen Plus Dynamics toolchain

Evaporators are integral parts of many separation processes across production industries, and they need to be well understood in order to be operated well, thereby enabling high resource-efficiency and productivity. In a previous investigation, the effects of disturbing oscillations in a two-stage evaporator system were quantified. In the current study, these oscillations were reduced through traj
