Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

This paper explores the long-term endurance of “breath” as a schema of personhood in the Austronesian-speaking world, from a comparative-ethnographic approach to the “Man with No Breath” figure featured in Philippine epics. This is one of two contributions from Myfel D. Paluga and Andrea Malaya M.…

We explored how to morphologically classify well-resolved jetted radio-loud active galactic nuclei (RLAGN) in the LOw Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) using machine learning.

A monthly seminar on complex networks, aimed at scientists from all disciplines.

Programs that aim to reduce symptoms of social anxiety in children generally include multiple components, such as exposure and cognitive restructuring. It is unknown if separate components yield positive intervention effects in children or whether a combination of components is required.

Due to the modern techniques of combinatorial chemistry and high-throughput screening, data on the biological activity of many millions of compounds is known. However, it is still very difficult to transfer this data into knowledge: if we know that compounds A and B bind to a certain protein with high…

Can a newly developed, app-based, personalized maintenance program enhance the effectiveness of the exposure-based one-session-treatment for children with a specific phobia?

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

To be able to measure small forces or small deviations from Boltzmann, the external vibrations at the resonance frequency must be very low. To achieve this, we have developed a very soft vibration isolation system and combine it with several other measures to reduce vibrations in our dilution refrigerators.…

The programme of the 3rd International Workshop on Klinefelter Syndrome, Trisomy X, and XYY. International Workshop theme: 'A life-course perspective'

This study aims to answer two main research questions: (1) What are the main predictors of work ability in employees with migraine? (2) Can we optimise work ability in employees with migraine using a web-based intervention focused on these relevant predictors?

What is the effectiveness of two school-based skills-training programs in promoting mental health?

Tens of thousands of soldiers and civilians have died as a result of Russia’s invasion of Ukraine in February 2022 and the continuing armed conflict. Many forms of critical infrastructure have been destroyed. Much of this devastation has been caused by weapons that utilise forms of artificial intelligence…
