Quantum–Kinetic Dark Energy (QKDE): A GR-preserving dark energy framework with a time-dependent scalar kinetic normalization Open
This work introduces Quantum–Kinetic Dark Energy (QKDE), a minimal extension of late-time cosmology that keeps General Relativity intact while allowing the kinetic normalization of a single scalar field to drift gently with cosmic time. By…

A matter of perspective: how nanoscale optical defects limit cosmic-scale gravitational wave observations Open
Ground-based gravitational-wave (GW) detectors, such as LIGO, Virgo, and KAGRA, have revolutionised as- tronomy. Now, future detectors like the Einstein Telescope and Cosmic Explorer aim to achieve even greater sensitivity. Advanced optica…

Discovery of active mouse, plant and fungal cytochrome P450s in endogenous proteomes and upon expression<i>in planta</i> Open
Eukaryotes produce a large number of cytochrome P450s that mediate the synthesis and degradation of diverse endogenous and exogenous metabolites. Yet, most of these P450s are uncharacterized and global tools to study these challenging, mem…

A <span>Before‐After Control‐Impact</span> experiment reveals that culling reduces the impacts of invasive deer on endangered peatlands Open
Invasive deer have undesirable impacts on native ecosystems. Culling is commonly used to reduce those impacts, but is expensive and sometimes controversial. It is therefore important to robustly assess how culling reduces the impacts of in…

A Semi-Automatic Method to Measure the Rotation of Sunspots Open
Sunspots have been observed to undergo rotation about their umbral centre. This is typically a slow rotation, with even the fastest sunspot rotations only reaching angular velocities of a few degrees per hour. This rotation may inject magn…

A Qualitative Investigation into the Representations of Habit by Lay People Open
Objective: There is continued debate regarding the most useful and meaningful way to measure habit and how to form habits via intervention. To date, lay representations of habit have rarely been explored. Such understandings may provide cl…

The mediating role of constructs representing reasoned-action and automatic processes on the past behavior-future behavior relationship Open
Objective: Past behavior has been consistently shown to predict and explain future behavior. It has been proposed that past behavior effects reflect both reasoned-action and automatic processes. The current study sought to explore the medi…

Beam Energy and Centrality Dependence of Direct-Photon Emission from Ultrarelativistic Heavy-Ion Collisions Open
The PHENIX collaboration presents first measurements of low-momentum (0.45 GeV/c), but when results from different collision energies are compared, an additional sqrt[s_{NN}]-dependent multiplicative factor is needed to describe the integr…
