On the effect of renormalization group improvement on the cosmological power spectrum
European Physical Journal C: Particles and Fields, 2018 Asymptotically safe quantum gravity predicts running gravitational and cosmological constants, while it remains a meaningful quantum field theory because of the existence of a finite number of non-Gaussian ultraviolet fixed points.

Developing World Bioethics, EarlyView.ABSTRACT Mental privacy is a growing concern as neurotechnologies and digital mental health tools collect and process sensitive brain‐related data. In South Africa, cultural and religious diversity adds complexity to protecting mental privacy, with traditional healing practices, communal decision‐making, and spiritual beliefs influencing mental health ...

Enchanting the Otherwise: Magical Realism and the Gendered Ontologies of Organizational Becoming
Gender, Work &Organization, EarlyView.ABSTRACT This paper enacts a feminist‐posthumanist reimagining of gender as ontological disturbance, using magical realism not as metaphor but as epistemological method. Rejecting representational logics and the managerial rationalities of organizational realism, we advance gender not as identity or role but as spectral interference—a transversal ...

Cosmological perturbations without inflation [PDF]
Classical and Quantum Gravity, 2016 A particularly attractive feature of inflation is that quantum fluctuations inthe inflaton field may have seeded inhomogeneities in the cosmic microwavebackground (CMB) and the formation of large-scale structure. In this paper,we demonstrate that a scalar field with zero active mass, i.e., with anequation of state $\rho+3p=0$, where $\rho$ and $p$ are ...

Hamiltonian cosmological perturbation theory [PDF]
Physics Letters B, 2006 The Hamiltonian approach to cosmological perturbations in general relativity in finite space-time is developed, where a cosmological scale factor is identified with spatial averaging the metric determinant logarithm. This identification preserves the number of variables and leads to a cosmological perturbation theory with the scalar potential ...

The Heythrop Journal, EarlyView.Abstract In this essay I contend that, whatever one might say about F.W.J. Schelling's historical and conceptual influence on Paul Tillich's doctrines, the overall style of Tillich's project can helpfully be dubbed Schellingian to the extent it mixes together discourses, genres, and vocabularies into an ever‐expanding whole. To the extent that anything

The ANT‐Mobilities Framework: Transectionality and a Post‐Materialist Historical Sociology
Sociology Lens, EarlyView.ABSTRACT The ANT‐Mobilities framework synthesizes Actor‐Network Theory, the mobilities paradigm, and historical sociology to analyze complex social transformations. This paper develops the framework through empirical engagement with post‐disaster rehabilitation networks following the 2005 Pakistan earthquake, demonstrating how crisis contexts generate ...

Meteoritics &Planetary Science, EarlyView.Abstract Within the Danian Scaglia Rossa Formation appears a regionally correlatable horizon cutting across multiple sections and outcrops within the Umbria–Marche Basin of NE Italy, where it is intercalated with uniform pelagic carbonate successions. This horizon is called “ALE layer” and has tentatively been interpreted as a fine‐grained volcanic ash.

Stardust Mine: A 2024 gabbroic shergottite from Arizona, USA
Meteoritics &Planetary Science, EarlyView.Abstract This study provides an initial characterization of Stardust Mine, a fresh gabbroic enriched shergottite collected in Arizona, USA, in September 2024 and is the first Martian meteorite to be unequivocably collected on US soil. Analysis was conducted on the type specimen and finds that Stardust Mine is composed of equal proportions of pyroxene ...
