A STEP IN STONE. ONTOLOGIES OF PODOMORPHIC PETROGLYPHS IN SOUTHERN SCANDINAVIAN BRONZE AGE

Oxford Journal of Archaeology, EarlyView.
Summary During the Bronze Age, a particular type of podomorphic petroglyph was produced on the outcrops by the sea in southern Scandinavia. In this text, their distribution, organization and articulation are analyzed in the Mälaren region of central‐eastern Sweden.

Extra-dimensional axion expectations

Journal of High Energy Physics
Axions arising as modes of higher-dimensional gauge fields are known to offer a compelling solution to the axion quality problem and to naturally arise in string theory.

Cross‐Species Plasticity and Divergence Under Alkaline Soil Signature Conditions Differentiating PYE From FIT Target Transcripts in the Arabidopsis thaliana Ferrome

Plant, Cell &Environment, EarlyView.
ABSTRACT Soil pH is an influential abiotic environmental factor. Here, we identify responses to central stimuli associated with calcareous alkaline soils in Arabidopsis and comparatively explore the potential of the closely related Arabidopsis halleri for addressing how plants cope with local soil pH.

High quality QCD axion via electric-magnetic duality

Journal of High Energy Physics
We propose a novel paradigm for the QCD axion with high-quality Peccei-Quinn (PQ) symmetry on the basis of electric-magnetic duality in the conformal window of a supersymmetric gauge theory.

Ecological niches and biogeography of nitrogen‐fixing plants in Europe

Plant Biology, EarlyView.
Despite sharing N fixation as a common trait, European legume and actinorhizal plant lineages occupy strikingly divergent ecological niches shaped by their evolutionary histories and physiological adaptations. Advanced symbiont control allows IRLC legumes to expand into northern, mesic regions, while non‐IRLC legumes are more common in Mediterranean ...

Heavy QCD axions at high-energy muon colliders

Journal of High Energy Physics
We study the physics potential of heavy QCD axions at high-energy muon colliders. Unlike typical axion-like particles, heavy QCD axions solve the strong CP problem with phenomenology driven by the anomalous gluon aG G ~ $$ \left( aG\overset{\sim }{G ...

New trajectories in the production of environmental knowledge about river restoration: contrasting scientific practices in Rhône River research

Restoration Ecology, EarlyView.
Abstract Introduction Restoration ecology relies on interactions between scientists and managers, yet these interactions are shaped by broader academic, social, and political contexts that influence how scientific knowledge is produced and mobilized. Objective This article aims to examine how scientific knowledge is produced within a long‐term river ...

Accidental Peccei-Quinn symmetry from gauged U(1) and a high quality axion

Journal of High Energy Physics
We construct explicit models that solve the axion quality problem originating from quantum gravitational effects. The general strategy we employ is to supplement the Standard Model and its grand unified extensions by an anomaly-free axial U(1) a symmetry
