On Non‐Compact Extended Bach Solitons

open access: yesMathematische Nachrichten, Volume 299, Issue 5, Page 1140-1151, May 2026.
ABSTRACT We study the characterization of non‐compact solitons of the extended Bach flow, known as an extended Bach soliton. We prove that a weakly conformally flat extended Bach soliton (Mn,g,V)$(M^n,g,V)$ with harmonic Weyl tensor is Bach‐flat and the potential vector field V$V$ is conformal.

Ethanol‐Responsive Nanostructures in Glycerol Monooleate/Triolein Dispersions

open access: yesMolecular Nutrition &Food Research, Volume 70, Issue 10, 27 May 2026.
Ethanol acts as a compositional trigger for nanostructural transitions in dispersed GMO and TO/GMO lipid nanocarriers. By modulating interfacial curvature and lipid packing, ethanol induces transformations from cubic to sponge, vesicular, and micellar structures, with macroscopic phase separation at elevated ethanol levels, enabling tunable lipid‐based

Deforming the Double‐Scaled SYK and Reaching the Stretched Horizon From Finite Cutoff Holography

open access: yesFortschritte der Physik, Volume 74, Issue 5, May 2026.
ABSTRACT We study the properties of the double‐scaled SYK (DSSYK) model under chord Hamiltonian deformations based on finite cutoff holography for general dilaton gravity theories with Dirichlet boundaries. The formalism immediately incorporates a lower‐dimensional analog of TT¯(+Λ2)$\text{T}\overline{\text{T}}(+\Lambda _2)$ deformations, denoted T2 ...

Autoparallels and the Inverse Problem of the Calculus of Variations

open access: yesFortschritte der Physik, Volume 74, Issue 5, May 2026.
ABSTRACT We prove that autoparallel curves associated with a torsion‐free but not necessarily metric‐compatible affine connection can be derived from an action principle. We explicitly construct the action functional and show by standard variational techniques that it produces the desired equations.

Stochastic Dynamics From Maximum Entropy in Action Space

open access: yesFortschritte der Physik, Volume 74, Issue 5, May 2026.
ABSTRACT We develop an information‐theoretic formulation of stochastic dynamics in which the fundamental stochastic variable is the total action connecting spacetime points, rather than individual paths. By maximizing Shannon entropy over a joint distribution of actions and endpoints, subject to normalization and a constraint on the mean action, we ...

Quantum Protocol Architectures and Secure Control Frameworks For 7G+ Networks: Standards, Synchronization, Use Cases, and Challenges

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 5, May 2026.
ABSTRACT Quantum‐native communication systems are reshaping secure, programmable, and coherence‐aware networking beyond the classical paradigm. As intelligent physical infrastructures, ranging from unmanned aerial vehicle swarms to satellite Quantum Key Distribution (QKD) platforms, demand trust, synchronization, and ultra‐reliability, conventional ...

Toward Efficient and Reliable Chemical Upgrading Using Solid Oxide Electrochemical Reactors, Mechanisms, Challenges, and Design Principles

open access: yesSmall, Volume 22, Issue 27, 14 May 2026.
Solid oxide electrochemical reactors (SOERs) offer a compelling pathway for coupling renewable electricity with chemical manufacturing, but their real application is still limited by low efficiency and instability. This review systematically summarizes SOER reaction mechanisms, performance‐limiting factors, and recent progress toward high‐efficiency ...

Active Particles in Tunable Compressible Environments

open access: yesSmall Science, Volume 6, Issue 5, May 2026.
Gold‐capped active microparticles powered by electric fields plough their way through a matrix of repulsive spheres, shoveling them aside. At high densities and field strengths, an initial strong direction fluctuation may compress the matrix asymmetrically and lead to an asymmetric reaction favoring sustained turns to the same side (spontaneous ...

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model

open access: yesSystems Research and Behavioral Science, Volume 43, Issue 3, Page 1212-1228, May/June 2026.
ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

Impact Plasma Amplification of the Ancient Mercury Magnetic Field

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Spacecraft measurements of Mercury indicate that it has a core dynamo with a surface field of 200–800 nT. These data also indicate that the northern hemisphere crust contains remanent magnetization likely produced by an ancient magnetic field. The inferred magnetization intensity is consistent with a wide range of paleofield strengths (0.2–50 ...
