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.

Evaluative conditioning (EC) is a key effect in attitude formation, leading to changes in the liking of neutral attitude objects due to their pairing with positive or negative stimuli. Despite EC's significance, current theories and most empirical findings are limited to stimulus pairings with a single affective stimulus at a time. In contrast, social environments often involve more complex combinations of affective stimuli.

In this paper, we present a new processing method, called MOSES-Impacts, for the detection of micrometer-sized damage on glass plate surfaces. It extends existing methods by a separation of damaged areas, called impacts, to support state-of-the-art recycling systems in optimizing their parameters. These recycling systems are used to repair process-related damages on glass plate surfaces, caused by accelerated material fragments, which arise during a laser-matter interaction in a vacuum.

The intracellular delivery of cargos via cell penetrating peptides (CPPs) holds significant promise as a drug delivery vehicle, but a major issue is their lack of cell type specificity, which can lead to detrimental off-target effects. We use an ADEPT-like concept to introduce conditional and selective activation of cellular uptake by using the lysine-rich, cationic, and amphiphilic L17E peptide as a model CPP. By masking the lysine residues of the L17E peptide with enzyme-cleavable acetyl protecting groups, the delivery of the covalently conjugated fluorophore TAMRA to HeLa cells was diminished.

We report on high-precision measurements that were performed with superconducting waveguide networks with the geometry of a tetrahedral and a honeycomb graph. They consist of junctions of valency three that connect straight rectangular waveguides of equal width but incommensurable lengths. The experiments were performed in the frequency range of a single transversal mode, where the associated Helmholtz equation is effectively one-dimensional and waveguide networks may serve as models of quantum graphs with the joints and waveguides corresponding to the vertices and bonds.

People prefer prototypical stimuli over atypical stimuli. The dominant explanation for this prototype preference effect is that prototypical stimuli are processed more fluently. However, a more recent account proposes that prototypes are more strongly associated with their category's valence, leading to a reversed prototype preference effect for negative categories.

Article Synopsis
  • Depression is linked to a higher risk of developing type 2 diabetes, with the study assessing the impact of current and persistent depressive symptoms on diabetes risk over a five-year period.
  • The analysis of data from over 15,000 participants indicated that current (recent) depression significantly increases the risk of developing type 2 diabetes, while a past history of depression alone did not show a notable effect.
  • The effect of depression on diabetes risk was similar for both men and women, suggesting that gender does not significantly modify this association.

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.

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.
