BackgroundSexual dysfunctions in individuals with social anxiety disorder (SAD) have been previously reported. However, most of these results refer to physical and behavioral measures. [...]

Green ammonia is emerging as a key enabler for decarbonizing fertilizer production and providing a renewable energy carrier. Its production from intermittent renewable power requires highly flexible operation of the Haber–Bosch process, which can cause rapid equipment deterioration without a suitable control strategy. [...]

Decarbonization targets for the maritime sector until 2050 require greenhouse gas (GHG) mitigation options like alternative fuels and on-board carbon capture (OCC). This study assesses GHG mitigation and side-effects of OCC via Life Cycle Assessment of two LNG-fueled ships, the large crane ship Sleipnir and an LNG carrier, and their distinct operational profiles. [...]

The treatment of ultrapure water with electrochemically produced O3 is a common means for disinfection yet leads to the formation of a variety of reactive oxygen species (ROS). The present study draws a comprehensive comparison between three commonly used photometric and fluorometric assays for ROS analysis and quantifies the individual signal responses for dissolved O3, ·OH and H2O2, respectively, to account for cross-sensitivities. [...]

BackgroundIsolated rapid-eye-movement behavior disorder (iRBD) often precedes the development of alpha-synucleinopathies such as Parkinson’s disease (PD). Magnetic resonance imaging (MRI) studies have revealed structural brain alterations in iRBD partially resembling those observed in PD. [...]

Background: The internet is a key source of health information, but the quality of content from popular search engines varies, posing challenges for users—especially those with low health or digital health literacy. To address this, the “tala-med” search engine was developed in 2020 to provide access to high-quality, evidence-based content. [...]

Resource allocation of wide-area internet networks is inherently a combinatorial optimization problem that if solved quickly, could provide near real-time adaptive control of internet-protocol traffic ensuring increased network efficacy and robustness, while minimizing energy requirements coming from power-hungry transceivers. In recent works we demonstrated how such a problem could be cast as a quadratic unconstrained binary optimization (QUBO) problem that can be embedded onto the D-Wave Advantage™ quantum annealer system, demonstrating proof of principle. [...]

‘Perennial wild plant mixtures’ (WPM) cultivation is a novel approach to combine biomass provisioning for biogas production with biodiversity enhancement at field scale in Germany. But the methane yield is about 40% lower compared with silage maize. [...]

The optimization of anion exchange membrane water electrolyzers (AEMWEs) relies on active, stable catalysts and well-designed catalyst layers. This study investigates the impact of tumbler ball milling on a nickel–iron layered double hydroxide (Ni3Fe-LDH) catalyst for the oxygen evolution reaction (OER). [...]
