Problems of code: ethnographic encounters with the Amazon Forest as a computational model

As environmental issues become increasingly datafied, computer code is becoming more important to the quotidian work of earth system scientists. Not only has code become central to their knowledge practices, it has become a way in which social relations travel through global know...

Innovation adoption across regions: psychological openness and the early diffusion of digital platforms

Early regional adoption is crucial for platform-enabled innovations because their viability depends on enough people within a region adopting them to generate network effects. Existing research on regional innovation diffusion explains early adoption largely through demographic,...

Agile in the Hybrid Era: Unpacking Meetings in Software Development

Hybrid work has become firmly established as a standard practice in software development in the post-pandemic era. In agile environments, meetings are pivotal for collaboration, making thoughtful consideration of their formats essential. This study explores how a broad range of r...

Asynchronous modal FRP: Ticking all the boxes

Over the past fifteen years, several languages for functionalreactive programming (FRP) have been suggested that use modaltypes to ensure properties like causality, productivity, and lack ofspace leaks. So far, almost all of these languages have included amodal operator for delay...

Adaptive cut reveals multiscale complexity in networks

Abstract Hierarchical clustering and community detection are important problems in machine learning and complex network analysis. A common approach to identify clusters is to simply cut dendrograms at some threshold. However, single-level cuts are often suboptimal in terms of cap...

Maximum List r-Colorable Induced Subgraphs in $$kP_3$$-Free Graphs

We show that, for every fixed positive integers r and k, Max-Weight List r-Colorable Induced Subgraph admits a polynomial-time algorithm on $$kP_3$$ -free graphs. This problem is a common generalization of Max-Weight Independent Set, Odd Cycle Transversal and List r-Coloring, amo...

Are fast test results preferable to high test sensitivity in contact-tracing strategies?

When an epidemic is spreading in a population, mitigation measures often rely on testing individuals, tracing possible secondary infections, and isolating known or suspected infected individuals. Because more accurate tests often take longer to analyse, and the benefits of contac...

Vocal encoding of heritable sociability prevails over emotions in sheep bleats

Vocalizations of animals are good indicators of their emotions. Temperament is known to influence the regulation and expression of emotions. However, how animal temperament affects their vocalizations and particularly their vocal expressions of emotions remains largely unexplored...

The effect of high-frequency light flicker on pattern-reversal and steady-state visual evoked potentials in healthy subjects

Abstract Purpose We investigated the effect of screen technology on visual evoked potentials (VEPs) by comparing a standard Cathode Ray Tube (CRT) screen with two Liquid Crystal Display (LCD) Light-Emitting Diode (LED) screens with differing levels of latency and high-frequency b...

Childhood body mass index trajectories and subtypes of endometrial cancer: A Danish cohort study

Background Obesity in adulthood is a well-established risk factor for endometrial cancer, a heterogeneous disease comprising several histological subtypes. Although childhood body mass index (BMI) is linked to endometrial cancer, the role of childhood growth patterns in different...

Towards molecular-based functional classification of fetal bovine serum

Quality and price of fetal bovine serum (FBS) are traditionally determined by geographical origin and parameters listed in the Certificate of Analysis (CoA). Despite its central role in cell culture, selecting suitable FBS batches remains costly and labor-intensive due to substan...

Integrating life cycle thinking into EU law on end‐of‐life vehicles

Abstract The European Union (EU) framework for end‐of‐life vehicles (ELVs) has progressed beyond waste disposal to formally cover vehicle design, producer responsibility and material recovery. However, it is less clear whether these provisions effectively connect across the relev...

Revealing Subject-Specific Temporal Patterns from Longitudinal Data

MOTIVATION: Temporal multivariate data is ubiquitous in many domains, for instance, being collected over time at planned visits (every few months/years) in longitudinal cohorts, or every few minutes/hours in challenge tests. The analysis of such data often focuses on revealing th...

lncRNAs contribute to caste differentiation as a regulatory layer in ants

Abstract Caste differentiation in ants represents one of the major evolutionary transitions and provides a unique model for studying developmental mechanisms underlying division of labor. Genetically identical individuals follow divergent epigenetically-regulated developmental tr...

Unlocking Scalable Ligand Residence Time Predictions with Koffee Unbinding Kinetics Simulations

A great number of drug discovery programs fail due to poor in vivo efficacy and ADMET liabilities. On- and off-target ligand residence times can act as important drivers of these problems. While modern experimental techniques have made measuring compound kinetics data more routin...

Compositional Neural-Cyber-Physical System Verification in the Interactive Theorem Prover of Your Choice

Formal verification of neuro-symbolic cyber-physical systems, such as drones, medical devices and robots, is complicated. Neural components must be trained to be optimal with respect to the available data as well as the safety specifications, and then verified using specialised s...

Hyperbolic confinement: self-assembly of asymmetric diblock co-polymers on triply periodic minimal surfaces

Abstract We investigate the self-assembly of compositionally asymmetric AB diblock co-polymers confined to thin hyperbolic films on the three cubic minimal surfaces: the primitive, the diamond and the gyroid. To analyse and quantify the assemblies, we use a computational pipeline...

A cross-cultural survey of Indigenous views on interspecies communication – Towards a consilience with scientific knowledge

Communication serves as a pivotal means for mutual understanding beyond species boundaries. Definitions of interspecific communication – particularly between humans and non-human organisms – vary not only across research disciplines, but also across cultures and societies driven...

Navigating the Battlefield: How Social Media Platforms Respond to Governance Demands From Legitimacy Communities in Geopolitical Conflicts

ABSTRACT Social media platforms have become central actors in governing online speech during geopolitical conflicts, navigating complex governance demands from diverse stake‐holding communities including states, civil society, and users. This paper explores these dynamics through...

A tale of ten cities: data bias in human mobility is pervasive and highly location specific

Abstract Large-scale human mobility datasets play increasingly critical roles in many algorithmic systems, business processes, and policy decisions. Unfortunately, there has been little focus on understanding bias and other fundamental shortcomings of these datasets and how they...
