Reslice3Dto2D: Introduction of a software tool to reformat 3D volumes into reference 2D slices in cardiovascular magnetic resonance imaging.

Objective: Cardiovascular magnetic resonance enables the quantification of functional and morphological parameters with an impact on therapeutical decision making. While quantitative assessment is established in 2D, novel 3D techniques lack a standardized approach. Multi-planar-reformatting functionality in available software relies on visual matching location and often lacks necessary functionalities for further post-processing.

Post-hoc standardisation of parametric T1 maps in cardiovascular magnetic resonance imaging: a proof-of-concept.

Background: In cardiovascular magnetic resonance imaging parametric T1 mapping lacks universally valid reference values. This limits its extensive use in the clinical routine. The aim of this work was the introduction of our self-developed Magnetic Resonance Imaging Software for Standardization (MARISSA) as a post-hoc standardisation approach.

The fight for power: historical women's movements of Russia and Great Britain in comparison.

In the second half of the 19th century, women began to organize worldwide to achieve the goal of gender equality. National women's movements emerged and were followed somewhat later by the first transnational political mobilization of women on a larger scale. The range of topics that were on the national and international agenda included, alongside the access to education and the enforcement of equal civil rights, as well as the fight for political participation, with the women's right to vote taking center stage.

Lazy Luna: Extendible software for multilevel reader comparison in cardiovascular magnetic resonance imaging.

Background And Objectives: Cardiovascular Magnetic Resonance (CMR) imaging is a growing field with increasing diagnostic utility in clinical routine. Quantitative diagnostic parameters are typically calculated based on contours or points provided by readers, e.g.

Inelastic mean-free path and mean escape depth of 10-140 eV electrons in SiO nanoparticles determined by Si 2p photoelectron yields.

We report on photoelectron spectra of SiO nanoparticles ( = 157 ± 6 nm) above the Si 2p threshold in the photon energy range 118-248 eV with electron kinetic energy 10-140 eV and analyze the photoelectron yield as a function of photon energy. Comparison of the experimental results with Monte-Carlo simulations on electron transport allows us to quantify the inelastic mean-free path and mean escape depth of photoelectrons in the nanoparticle samples. The influence of the nanoparticle geometry and electron elastic scattering on photoelectron yields is highlighted.

Introduction of a cascaded segmentation pipeline for parametric T1 mapping in cardiovascular magnetic resonance to improve segmentation performance.

The manual and often time-consuming segmentation of the myocardium in cardiovascular magnetic resonance is increasingly automated using convolutional neural networks (CNNs). This study proposes a cascaded segmentation (CASEG) approach to improve automatic image segmentation quality. First, an object detection algorithm predicts a bounding box (BB) for the left ventricular myocardium whose 1.

Introduction of Lazy Luna an automatic software-driven multilevel comparison of ventricular function quantification in cardiovascular magnetic resonance imaging.

Cardiovascular magnetic resonance imaging is the gold standard for cardiac function assessment. Quantification of clinical results (CR) requires precise segmentation. Clinicians statistically compare CRs to ensure reproducibility.

Revealing the formation mechanism and band gap tuning of SbS nanoparticles.

SbS is a promising nanomaterial for application in solar cells and in the fields of electronics and optoelectronics. Herein, SbS nanoparticles were prepared via the hot-injection approach. In contrast to earlier work, the reaction temperature was decreased to 150 °C so that the reaction was slowed down and could be stopped at defined reaction stages.

Effect of different silica coatings on the toxicity of upconversion nanoparticles on RAW 264.7 macrophage cells.

Upconversion nanoparticles (UCNPs), consisting of NaYF doped with 18% Yb and 2% Er, were coated with microporous silica shells with thickness values of 7 ± 2 and 21 ± 3 nm. Subsequently, the negatively charged particles were functionalized with -(6-aminohexyl)-3-aminopropyltrimethoxysilane (AHAPS), which provide a positive charge to the nanoparticle surface. Inductively coupled plasma optical emission spectrometry (ICP-OES) measurements revealed that, over the course of 24h, particles with thicker shells release fewer lanthanide ions than particles with thinner shells.

Coating of upconversion nanoparticles with silica nanoshells of 5-250 nm thickness.

A concept for the growth of silica shells with a thickness of 5-250 nm onto oleate-coated NaYF:Yb/Er upconversion nanoparticles (UCNP) is presented. The concept enables the precise adjustment of shell thicknesses for the preparation of thick-shelled nanoparticles for applications in plasmonics and sensing. First, an initial 5-11 nm thick shell is grown onto the UCNPs in a reverse microemulsion.

Millennials: sickness presenteeism and its correlates: a cross-sectional online survey.

Objective: Sickness presenteeism (SP) is a well-documented phenomenon in the current workforce. However, little is known about the SP of future employees (Millennials). We investigated rate and propensity of presenteeism and health-related and work-related correlates in university students to obtain information about the relevance of SP in the future workforce.

Lessons Learned From Applications of the Stage Model of Self-Regulated Behavioral Change: A Review.

Stage models are becoming increasingly popular in explaining change from current behavior to more environmentally friendly alternatives. We review empirical applications of a recently introduced model, the stage model of self-regulated behavioral change (SSBC). In the SSBC, change toward pro-environmental behavior takes place in four, qualitatively different stages (predecisional, preactional, actional, and postactional) which are each influenced by constructs taken from theories previously established to describe and predict pro-environmental behavior.

Using Card Sorting to Explore the Mental Representation of Energy Transition Pathways Among Laypeople.

Meeting international emission targets will require major changes in the energy system. This paper addresses the public perception of different pathways to energy transition, and their mental representation in particular. A study is reported that employed card sorting to explore how laypeople categorize possible pathway components with respect to their perceived similarity (Norwegian sample, = 61; German sample, = 71).

Gathering, evaluating and managing customer feedback during aircraft production.

This paper proposes a systematic approach for gathering requirements during production through customers' remote access to the partially and fully assembled aircraft and its modules. The paper also proposes an evaluation and management of these recorded requirements and their utilization in the development of an aircraft. Modular product architecture is used for the modular organization of the product, product-service, and production system for the gathering, evaluation and management of feedback for product development perspectives.

Problem gambling and the five-factor model of personality: a large population-based study.

Background And Aims: Knowledge of the personality characteristics of individuals who develop gambling problems is important for designing targeted prevention efforts. Previous studies of the relationship between the five-factor model of personality and gambling problems were based on small samples not representative of the general population. We estimated differences in neuroticism, extroversion, intellect, agreeableness and conscientiousness between non-problem gamblers and individuals with low, moderate and severe gambling problems.
