Experimental investigation of Coandã flow attachment in automotive windshield defrosting
Abstract This paper examines the occurrence of the Coandã effect in the context of automotive windshield defrosting. A generic, parameterized pseudo-2D test rig representing the main windshield defrosting components of a passenger vehicle is introduced. By externally controlling...

High‐Efficiency Deep Blue Single‐Gaussian Europium(II) Emitters and Their Emitter‐Host Interactions
ABSTRACT Eu(II) complexes are attractive emitters for deep‐blue organic light‐emitting diodes (OLEDs) due to their narrow, parity‐allowed 4 f –5 d emission; however, their implementation in vacuum‐processed OLEDs has remained limited. Here, we introduce a new molecular design con...

The evolution of the Dutch heat early warning system (2007 - 2025)
Heat early warning systems (HEWS) are critical tools for anticipating hazardous heat and enabling timely response. While some of the earliest systems were developed over two decades ago, little is known about how they have evolved in practice. This study examines the evolution of...

Genomic consequences of admixture in an experimentally founded sand lizard population
Abstract Conservation interventions are increasingly required for species threatened by population declines and isolation due to anthropogenic pressures. Small, isolated populations are particularly vulnerable to the loss of genetic diversity, increased inbreeding, and the accumu...

The chromomagnetic moment of a heavy quark with hyperasymptotic precision
A bstract We determine the normalization of the leading infrared renormalon of the chromomagnetic moment of a heavy quark. Estimates of higher order coefficients of the perturbative series are given. We compute the hyperfine splitting of the B and D mesons for the ground state wi...

Do green bonds deliver? Environmental outcomes and greenwashing tests in Europe
Green bonds are designed to finance sustainable projects, acting also as a signal of firms’ commitment to environmental goals. Using a panel of European-based firms over 2013–2024, we examine whether green bond issuance is followed by significant environmental improvements. Compa...

Density matrix of de Sitter JT gravity
A bstract Jackiw-Teitelboim (JT) gravity in two-dimensional de Sitter space is an intriguing toy model for a quantum mechanical description of an inflationary phase of the universe, including initial conditions. Starting from exact solutions of the Wheeler-DeWitt equation, we stu...

GRACE-OFF: A Machine-Learned Interatomic Potential for Organic Liquids Using the GRACE Architecture
Abstract Machine-learned interatomic potentials (MLIPs) have become an increasingly important tool for molecular dynamics (MD) simulations, enabling near quantum-mechanical accuracy at significantly reduced computational cost. Recent studies indicate that the Graph Atomic Cluster...

Almost 200 years of anthocyanin research: What we know, what we assume and what remains unknown
Flavonoids are frequently presented as health-beneficial plant metabolites, and their subclass anthocyanins is best known for striking flower colours. The biosynthesis of flavonoids has been studied for decades and has developed into a model system in plant biology. Despite thous...
