Understanding driver deviations from intended routes under social routing recommendations in navigation apps

To understand drivers’ route choice behavior under social routing recommendations, this study investigates data from a mobile navigation app that captures drivers’ stated route intentions before trips and their actual trajectories during trips. An inconsistency can occur when dri...

Large deviations of SLE0+ variants in the capacity parameterization

We prove large deviation principles (LDPs) for full chordal, radial, and multichordal SLE0+ curves parameterized by capacity. The rate function is given by the appropriate variant of the Loewner energy. There are two key novelties in the present work. First, we strengthen the top...

The Mobile Hospital delivers outreach acute care to nursing homes: healthcare staff interviews

Abstract Background Nursing home residents often face unnecessary risks when visiting the emergency department (ED). Due to the limited rapid response capabilities of primary care and lack of equipment for acute illnesses, onsite specialized outreach units present a novel alterna...

Automated Structure Discovery for Tip-Enhanced Raman Spectroscopy

Tip-Enhanced Raman Spectroscopy (TERS) provides nanoscale chemical fingerprints alongside high-resolution topographic mapping of molecules, offering a powerful tool for materials discovery. However, TERS image datasets are challenging to interpret and typically demand time-consum...

Intraoperative monitoring of myocardial oxygenation during open-heart surgery: feasibility and initial performance

Abstract Myocardial protection during cardiopulmonary bypass relies on intermittent administrations of cardioplegia without continuous, tissue‑level feedback on myocardial oxygen supply and mitochondrial metabolic status. Extended near‑infrared spectroscopy (eNIRS) can enable rea...

ChatGPT Sensemaking and Appropriation in Everyday Life

ChatGPT has been adopted at an unprecedented pace, yet the processes through which people explore, adapt, and integrate it into everyday lives remain underexplored. We analyzed 300 Reddit comments and conducted 20 interviews, synthesizing insights from both collective sensemaking...

Propulsion and attitude control for Foresail-2: harnessing water electrolysis propulsion in a 6U CubeSat mission

Abstract The Foresail-2 mission, a 6U CubeSat developed by the Finnish Center of Excellence in Research of Sustainable Space, seeks to investigate ultra-low-frequency waves in the inner magnetosphere and validate innovative de-orbiting technologies. The mission’s demanding attitu...

Poisson subspace clustering: focusing on the essentials in count data

Abstract Count data represented as a matrix of non-negative integer values, such as contingency tables, are prevalent across diverse domains. When clustering such data sets, specific methods are required, as generic algorithms often fail to consider their unique distributional pr...

The Importance of Thermodynamic Data for Pyrrole Pyrolysis and Combustion Chemistry

In this work, the CCSD(T)/Extrapolate(3/4,def2)//PBE0/def2‐QZVP levels of theory were utilized in ORCA 6.1.1 to derive enthalpy and entropy of formation at 298.15 K for 32 species that include both radicals and stable molecules relevant to the pyrolysis and combustion of pyrrole....

Heroism as cultural ferment: Reframing entrepreneurial agency in the polycrisis

This research note re-centers heroic entrepreneurial agency by foregrounding heroism as cultural ferment. Previous critical literature has largely converged on an anti-heroic vision of entrepreneurship, thereby downplaying individuals’ capacity for agency. Yet it is precisely thr...

From search agents to dissemination interfaces: understanding human trust in health information from conversational search

Large Language Models (LLMs) deployed through Conversational User Interfaces (CUIs) are transforming health information-seeking by offering immediate, interactive experiences compared to traditional search engines like Google. However, how trust is influenced by both the types of...

Thermodynamic Aspects of Mixed-Linkage Glucan and Nanocellulose Interactions

Abstract This study addresses knowledge gaps concerning interactions between barley mixed-linkage glucans (MLGs) and TEMPO-oxidized cellulose nanocrystals (TCNC), focusing on underlying physiochemical and thermodynamic principles. Combining dynamic light scattering (DLS), quartz...

Characterization and stability assessment of rare earth tailings under dry and paste stacking conditions

The management of rare earth element (REE) tailings presents unique challenges due to their fine-grained nature, carbonate-rich composition, and potential environmental sensitivity. As Europe develops new carbonatite and phosphate-hosted REE projects, large volumes of tailings wi...

Flying through the plasmasphere to optimize low-energy ion measurements

The Juice flyby of Earth in August 2024 gave us the first chance to evaluate the performance of the Jovian Plasma Dynamics and Composition analyzer (JDC) in environments similar to those expected at Jupiter. JDC is one of the sensors belonging to the Particle Environment Package...

Estimating Mutual Information and Pearson Correlation on Neural Evoked Responses

Abstract In neural evoked responses, small variations in the timing or duration of responses can be observed when the same functional response is recorded in different trials, different experimental conditions or by different sensors. These variations limit the ability of correla...

Hunting grounds for predatory publishers

Abstract Are some preprint platforms more attractive to predatory publishers than others? To explore this question, we analyze unsolicited messages received for a research paper spanning the social and health sciences. The paper was posted on two major preprint platforms: Researc...

Stereometric Molecular Engineering for Ultra‐Stable Aqueous Zinc‐Ion Batteries

ABSTRACT Aqueous zinc‐ion batteries (AZIBs) offer a safe and low‐cost energy storage platform yet are plagued by interfacial instability. Here, we investigate the relationship between molecular stereoisomerism and interfacial adsorption using inositol as a model system. Theoretic...

Comparison of Virgin LDPE and an Industrial Multilayer Plastic Film in a Continuous Pilot-Scale Fluidized-Bed Pyrolysis Reactor

Abstract Thermal pyrolysis of industrial multilayer plastic film was experimentally investigated in a pilot-scale fluidized-bed reactor with steam as the carrier gas. Experimental design was constructed by using two different feeds: virgin-quality LDPE and multilayer plastic (MLP...

Can Common Recycling Targets Deliver Convergence? Evidence From EU Municipal Waste Recycling, 2004–2023

ABSTRACT The EU Waste Framework Directive sets common municipal waste recycling targets for all Member States, yet large cross‐country gaps persist. This paper examines whether EU‐27 recycling rates converged over 2004–2023, whether convergence stalled after 2018, and which facto...

Fingerprinting Superconductors by Disentangling Andreev and Quasiparticle Currents Across Tunable Tunnel Junctions

ABSTRACT Tunneling Andreev reflection (TAR) spectroscopy provides a new approach to identify superconducting pairing symmetry at the atomic scale. Using atomistic superconducting transport simulations, we reveal the mechanism by which TAR can distinguish between pairing symmetrie...
