Analytical applications of molecularly imprinted polymers: a personal view

Abstract Molecularly imprinted polymers (MIPs) are biomimetic counterparts of biomacromolecules that are synthesized by templating the target within a polymeric network. While the affinity of MIPs can compete with that of antibodies, the specific activity of natural enzymes remai...

Quantum circuits, hypercubeharmonic, and remote networked improvisation: a case study

Abstract Mathematics and theoretical physics not only allow us to investigate musical artworks, but also fuel artistic creativity and imagination. In this paper, we present an artistic framework inspired by mathematics and physics. We describe the HyperCubeHarmonic (HCH), an inte...

Agentic AI, medical morality and the transformation of the patient–physician relationship

Agentic artificial intelligence (AI) is an emerging development in the digital transformation of healthcare. Unlike conventional generative AI, agentic AI systems can perform autonomous, goal-directed actions and coordinate complex tasks. They promise to support or even collabora...

Valency (mis)matches in Baltic languages: contact, prefixation, and genealogy

Abstract This study investigates valency patterns in Latvian and Lithuanian using parallel film subtitles. The data reveals about 2.5 valency matches for every mismatch, with most matches stemming from parallel monovalent and transitive constructions. Systematic mismatches are at...

Metascience, Research Software, and the Case for RS Metascience: Extended Preprint

Metascience is the study of science itself, including how scientific research is conducted, evaluated, and improved. Rather than asking questions about the natural or social world, metascience asks questions about scientific research -- its methods, objects of study, participants...

Personality traits of entrepreneurs and the size of their firms

Abstract Personality research in entrepreneurship often focuses on venture entry and survival, leaving personality traits associated with firm size underexamined. Using novel data from the German Socio-Economic Panel that include a sample of owner-managers running larger firms, w...

Machine learning-based rescoring with MS²Rescore boosts peptide identification and taxonomic specificity in metaproteomics

Abstract Background Metaproteomics, the study of the collective proteome within microbial ecosystems, has gained increasing interest over the past decade. However, peptide identification rates in metaproteomics remain low compared to single-species proteomics. A key challenge is...

Shallow Landslides Align With Atmospheric Rivers in Coastal Steeplands

Abstract Rapid, shallow landslides in coastal mountains are triggered by extreme precipitation, shaping topography and impacting human settlements. Using an inventory of >700 landslides mapped from satellite imagery (2009–2024) and an atmospheric river database (1981–2019), this...

Developers’ Experience with Generative AI Beyond Productivity Assessment – Insights from an Empirical Mixed-Methods Field Study

With the growing adoption of AI-powered coding assistants, organizations and developers are increasingly seeking to optimize their interaction with these tools. Prior research has largely focused on output quality and productivity gains, with limited attention paid to developers’...

Geometric morphometric analyses of intragenus (Campylomormyrus) and intergenus hybrids in mormyrid fish

Abstract Natural hybrids within the weakly electric mormyrid fish genus Campylomormyrus have not been documented in the wild. However, recent advances have enabled the artificial production of both intragenus ( Campylomormyrus ) and intergenus ( Campylomormyrus and Gnathonemus )...

Quantifying non-Markovianity in magnetization dynamics via entropy production rates

Abstract Magnetization dynamics is commonly described by the stochastic Landau-Lifshitz-Gilbert (LLG) equation. However, on picosecond timescales, inertial and open-system extensions of the LLG equation are necessary to interpret recent experiments. While it has been anticipated...

From Idea to Energy: Examining the Relationship Between Creativity at Work and Vigor

Abstract: Although there are high expectations regarding employee creativity, its impact on individuals is insufficiently explored. This study investigates whether and how creativity benefits energy. We propose that workplace creativity is positively linked to vigor, mediated by...

Spectral analysis of groundwater level time series for robust estimation of aquifer response times

Abstract. Groundwater resources represent Germany's most important source of freshwater but they are increasingly under pressure. Climate change, societal developments, and rising abstraction rates are impacting subsurface storage in ways that are currently difficult to predict,...

A Theoretical Investigation of Nonadiabatic Dynamics and Time-Resolved NEXAFS Spectra of Uracil

Abstract Uracil, a fundamental RNA nucleobase, exhibits complex excited-state dynamics governed by nonadiabatic processes that prevent photodamage. Upon photoexcitation, population initially reaches the bright ππ* (S2) state and subsequently relaxes to the dark nπ* (S1) state via...

Ecological momentary insights into cannabis use and its contexts: a pre-post legalization study in Germany

Abstract Globally, cannabis ranks third in psychoactive substance prevalence after nicotine and alcohol, with heavy use linked to psychosis, anxiety, and depression. However, real-time data on how legal reforms influence consumption remain scarce. This Ecological Momentary Assess...

Ancient DNA reveals early use of melons in China’s Song dynasty

Abstract Melon ( Cucumis melo L.) domestication is thought to have occurred independently once in Northeast Africa and twice in India, but archaeobotanical seed remains point to a possible additional domestication in China. Because Cucumis seeds are difficult to diagnose morpholo...

Spin Polarized Transport in Copper Oxide Atomic Junctions Revealed by Anomalous Shot Noise Behavior in the Presence of the Kondo Effect

Abstract Noise measurements provide a valuable tool for revealing spin polarization effects in the electronic transport through quantum coherent conductors. We present an extension of the Landauer description of shot noise to include energy dependent transmission functions and ap...

Structural variation landscape reveals phenotypic divergence across cocoa populations

Abstract Structural variations (SVs) represent an important source of genomic diversity and can contribute substantially to phenotypic variation in crops. However, the population-scale distribution and phenotypic effects of SVs in Theobroma cacao L. (cocoa) remain poorly understo...

Animal Individual Factors Dictate Learning Strategy: An Integrated Analysis of Cattle Adaptation to a Virtual Fencing System

Virtual fencing (VF) is a promising technology for pasture management, but its successful implementation depends on understanding the factors that influence the animal learning. The aim of the present study was to evaluate the significance of individual animal factors that affect...
