From homophily to exclusion in small social systems.

The actors are placed at nodes of the complete weighted graph. They are endowed with densities of contact with the other actors and with positions in a social hierarchy. These characteristics evolve in time according to the homophily principle and the Matthew effect.

A family with gallstone disease: defining inherited risk in the era of clinical genetic testing.

Gallstones are among the most frequent hepatobiliary conditions. Although in most cases, they remain asymptomatic, they can cause complications and, in such cases, invasive treatments like endoscopic retrograde cholangiography (ERC) or cholecystectomy are required. Here, we present the results of genetic testing of a single family with a high incidence of symptomatic gallstones and cholestatic liver phenotypes.

Support for temporary protection of displaced populations in the EU: A conjoint experiment.

Millions of people were forced to flee Ukraine after Russia's invasion on February 24, 2022, one of the fastest displacements in decades. Citizens' response in EU countries (where most displaced Ukrainians arrived) has been considerably more positive than in past refugee crises. This study investigates several possible drivers of this difference.

Optical excitation and detection of high-frequency Sezawa modes in Si/SiO system decorated with NiFe nanodot arrays.

Surface acoustic waves have emerged as one of the potential candidates for the development of next-generation wave-based information and computing technologies. For practical devices, it is essential to develop the excitation techniques for different types of surface acoustic waves, especially at higher microwave frequencies, and to tailor their frequency versus wave vector characteristics. We show that this can be done by using ultrashort laser pulses incident on the surface of a multilayer decorated with a periodic array of metallic nanodots.
