Population Density and Air Pollution: Should Incentives Be the Same Across U.S. Cities and States?

Population concentration generates both economic benefits and environmental costs through agglomeration-related spatial externalities. This paper examines how population density shapes fine particulate matter (PM2.5) concentrations across U.S. states over the period 2000–2023, conceptualizing density as a structural dr...

Consumer Preferences for Electric Vehicle Fuel Taxation: The Role of Revenue Recycling and Tax Salience in South Korea

The rapid diffusion of electric vehicles (EVs) is weakening the conventional fuel tax base, creating new challenges for transport-energy taxation. Although South Korea does not currently tax EV charging electricity, such taxation is becoming increasingly relevant as EV adoption expands. This study examines consumer pre...

Learning Memory Operators with Physics-Informed Neural Networks: State Recovery, Kernel Reconstruction, and Parameter Identifiability

Memory-dependent evolution equations replace the time derivative of the state with a convolution against a memory kernel \( K(t) \), and appear throughout anomalous diffusion, viscoelasticity, and tumour-growth modelling.\( K \) is usually fixed a priori, most often to the power-law kernel of a Caputo fractional deriva...

POSTELLAR: Posterior Stellar Spectrum Sampling—An Alternative to Approximate Stellar Spectra for Exoplanetary Analysis

Abstract We present a novel approach to perform posterior sampling of the underlying stellar spectrum in high-resolution spectroscopic observations. Our method, postellar , coherently combines information from empirical observations and physics-based models, enabling more accurate spectral recovery while providing unce...

Oscillatory active Brownian motion: A minimal model for sperm dynamics

Abstract Active biological microswimmers typically combine persistent self-propulsion with cyclic motion generated by flagellar or ciliary beating. However, standard active Brownian motion (ABM) does not explicitly account for these intrinsic oscillations. This limitation is particularly relevant for sperm cells, whose...

Impacts of Fermi Level Pinning at Hole‐Selective Contacts in CdSeTe/CdTe Solar Cells

ABSTRACT P‐type doped CdTe free surfaces, Schottky contacts, and even interfaces with isostructural p‐ZnTe frequently exhibit downward band bending and moderate to high recombination velocities. Fermi level pinning by donor‐like states can explain these band diagram features, as well as CdTe‐based solar cell characteri...

NextCrystal: a Symmetry-Driven Generative Framework for Crystal Structure Prediction

Abstract Crystal structure prediction (CSP), which aims to predict the 3D atomic arrangement of a crystal from its composition, is central to materials discovery and mechanistic understanding. Crystal symmetry plays a crucial role in CSP, but given the composition in a unit cell, existing methods either struggle with t...

Data for reproducing figures in Mathematical modelling of cell layer growth in a hollow fibre bioreactor

Generating autologous tissue grafts of a clinically useful volume requires efficient and controlled expansion of cell populations harvested from patients. Hollow fibre bioreactors show promise as cell expansion devices, owing to their potential for scale-up. However, further research is required to establish how to spe...
