Tracing the evolution of the molecular gas content in galaxies is critical for a complete understanding of galaxy formation and evolution, as it provides the direct fuel for star formation. Studies of high-redshift (z>1) molecular gas reservoirs, most commonly traced by carbon monoxide (CO), have seen…

In 1940 the Germany occupiers ordered the dismissal of all Jewish staff of the university. This resulted in protest speeches by fellow academics.

The type-IV secretion system (T4SS) is a machinery able to transfer DNA and proteins between bacteria and in certain cases also to eukaryotic cells.

The symposium is open to all registered participants and consists of a one-day programme and a poster session.

In recent years, the use of primary data in terrorism research has increased. In order to maximise the benefits of this trend, we want to encourage terrorism scholars to implement open science practices more systematically. This article therefore presents different avenues towards open and reproducible…

Alzheimer's disease (AD) is the most frequent neurodegenerative disorder and the primary cause of dementia. The neuropathological features of AD include the occurrence of senile plaques, neurofibrillary tangles, decreased synaptic density, and loss of neurons. An obstacle in the study and treatment…

We aim to unravel the molecular mechanisms involved in the transformation of eukaryotic cells by Agrobacterium.

An exploration across thirteen essays by critics, translators and creative writers on the modern-day afterlives of Old English, delving into how it has been transplanted and recreated in the twentieth and twenty-first centuries.

Surreal Geographies recovers a forgotten archive of Holocaust representation. Examining art, literature, and film produced from the immediate postwar period up to the present moment, Kathryn L. Brackney investigates changing portrayals of Jewish victims and survivors.

Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

Low-carbon (LE) technologies have a significant potential to reduce the total carbon emissions in China.

The Leiden Slavery Studies Association (LSSA) is dedicated to promoting a greater understanding of slavery and post-slavery in any period and any geographical region.

This project envisions a broad evaluation of 20th century models of human development over the life course (ontogenesis, human constitution), including socialist and capitalist conceptions across both Eastern and Western Europe.

Understanding the water use of power production is an important step to both a sustainable energy transition and an improved understanding of water conservation measures. However, there are large differences across the literature that currently present barriers to decision making.

An Active Galactic Nucleus (AGN) is a highly luminous region at the center of a galaxy, powered by the accretion into a supermassive black hole and emitting energy from radio waves to gamma rays, often outshining the host galaxy.

The Rise and Decline of an Iberian Bourgeoisie is one of the first long-term studies in English of an Iberian town during the late medieval crisis. Focusing on the Catalonian city of Manresa, Jeff Fynn-Paul expertly integrates Iberian historiography with European narratives to place the city's social,…

Migration and Mobility in the Early Roman Empire by Luuk de Ligt and Laurens E. Tacoma (Eds.)

This series provides a venue for scholarly work—research monographs and edited volumes—that advances our understanding of the history of slavery and post-slavery in any period and any geographical region. It fills an important gap in academic publishing and builds upon two relatively recent developments…
