The Once and Future Hydrology Is Whole Earth Hydrology

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract We here argue for a new paradigm to advance pursuit of truth in global freshwater science. Our proposed Whole Earth Hydrology is hydrology that is explicitly empirical and discovery‐based, grounded in primary data, detailed at scale, and incorporates humans as essential.

Relational dynamics and Page-Wootters formalism in group field theory [PDF]

Quantum
Group field theory posits that spacetime is emergent and is hence defined without any background notion of space or time; dynamical questions are formulated in relational terms, in particular using (scalar) matter degrees of freedom as time.

Advancing Digital Transformation in Material Science: The Role of Workflows Within the MaterialDigital Initiative

Advanced Engineering Materials, Volume 27, Issue 8, April 2025.
The MaterialDigital initiative drives the digital transformation of material science by promoting findable, accessible, interoperable, and reusable principles and enhancing data interoperability. This article explores the role of scientific workflows, highlights challenges in their adoption, and introduces the Workflow Store as a key tool for sharing ...

Acoustic Rayleigh Wave Turbulence in Soft Viscoelastic Matter

Advanced Science, Volume 12, Issue 15, April 17, 2025.
Discrete acoustic Rayleigh wave turbulence (DARWT) is observed on the free surface of viscoelastic materials under monochromatic excitation. Governed by bulk shear rigidity supporting inertial modes against surface tension, the nonlinear Rayleigh waves exhibit distinct power‐law scaling and turbulence features in their Kolmogorov–Zakharov spectra. This

The Space of Connections as the Arena for (Quantum) Gravity

Symmetry, Integrability and Geometry: Methods and Applications, 2011
We review some properties of the space of connections as the natural arena for canonical (quantum) gravity, and compare to the case of the superspace of 3-metrics.

4D Biofabrication of Magnetically Augmented Callus Assembloid Implants Enables Rapid Endochondral Ossification via Activation of Mechanosensitive Pathways

Advanced Science, Volume 12, Issue 15, April 17, 2025.
Magnetically augmented biohybrid cartilaginous microtissues enable remote microtissue motion control and assembly as well as targeted differentiation. This study demonstrates accelerated endochondral ossification under magnetic stimulation, highlighting cartilaginous assembloid constructs’ ability to retain long‐term magnetic properties.

Quantum-Wave Equation and Heisenberg Inequalities of Covariant Quantum Gravity

Entropy, 2017
Key aspects of the manifestly-covariant theory of quantum gravity (Cremaschini and Tessarotto 2015–2017) are investigated. These refer, first, to the establishment of the four-scalar, manifestly-covariant evolution quantum wave equation, denoted as ...

THOR2: Topological Analysis for 3D Shape and Color‐Based Human‐Inspired Object Recognition in Unseen Environments

Advanced Intelligent Systems, Volume 7, Issue 4, April 2025.
This work addresses the challenge of object recognition by mobile robots in previously unseen, cluttered indoor spaces. It introduces a new human cognition‐inspired recognition framework that uses topological analysis to encode object 3D shapes and colors from camera images.

Entropic Forces and Newton’s Gravitation

Entropy, 2020
Our subject of interest here is entropic forces, as re-interpreted by Verlinde with reference to gravitation, that is, by appealing to Verlinde’s conception of an entropic (statistically emergent) gravity advanced in [Physica A 2018, 511, 139].

Roadmap on Weak Measurements in Optics

Advanced Physics Research, Volume 4, Issue 4, April 2025.
Quantum weak measurements have attracted considerable recent attention for both addressing fundamental questions in quantum mechanics and for numerous potential applications. This review aims to compile both the fundamental aspects and the ongoing metrological applications of weak measurements in the domain of quantum and classical optics in a concise ...
