Work Versus Force: Simultaneous Processes for Describing Interactions
Advanced Physics Research, EarlyView.ABSTRACT Achieving a unified description of interactions remains an open challenge in theoretical physics, which currently describes four fundamental forces. This situation may be viewed differently when interactions are formulated in terms of processes (work as actio) rather than forces (force as actio), not only at the macroscopic level but also at ...

Deep Learning Spinfoam Vertex Amplitudes: The Euclidean Barrett–Crane Model
UniverseSpinfoam theories propose a well-defined path-integral formulation for quantum gravity, and it is hoped that they will provide the dynamics of loop quantum gravity. However, it is computationally hard to calculate spinfoam amplitudes.

Quantifying the Impact of Relativistic Precession on Tidal Disruption Event Light Curves
Astronomische Nachrichten, EarlyView.ABSTRACT The tidal field of a black hole can turn a star into a gas stream whose orbit can precess, especially if the a black hole is rapidly spinning. In this work, we investigate the impact of precession on the light curves of tidal disruption events (TDE).

Business Strategy and the Environment, EarlyView.ABSTRACT Drawing upon ecological modernization theory as the analytical framework, this study employs macro‐level longitudinal tracking data covering China's major regions as research samples. It measures the green and low‐carbon development (GLCD) of manufacturing from the four dimensions—“carbon reduction, pollution mitigation, ecological expansion ...

Carbon Energy, EarlyView.Recent strategies address these challenges through ion‐specific regulation, encompassing chloride‐tolerant and chloride‐regulating anodes together with cathode designs that suppress OH− accumulation and Mg2+/Ca2+ coupling. This ion‐management‐oriented framework provides general guidelines for achieving stable, selective, and scalable seawater ...

Sodium Tetraazidoaurate(III)—From Na[AuCl4]·2H2O to Na[Au(N3)4] and Beyond One Step at a Time
Chemistry – A European Journal, EarlyView.Novel sodium chlorido‐/azidoaurate(III) dihydrates Na[AuCl4–x(N3)x]·2H2O (x = 0, 1, 2, 3, 4) provide the first example of a complete series of gradual substitution on tetramer complex anions to be described. Controlled dehydration of Na[Au(N3)4]·2H2O leads to Na[Au(N3)4]·H2O and Na[Au(N3)4], the latter being a highly explosive material.

Quantum Field Theory of Black Hole Perturbations with Backreaction: I General Framework
UniverseIn a seminal work, Hawking showed that natural states for free quantum matter fields on classical spacetimes that solve the spherically symmetric vacuum Einstein equations are KMS states of non-vanishing temperature.
