Validation of Physics‐Based Simulated Accelerograms for Seismic Fragility Analyses of Italian RC Existing Building Types

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
This article aims at exploring and validating the use of 3D physics‐based simulated ground motions as seismic input for the derivation of seismic fragility curves based on nonlinear dynamic numerical analyses. Fragility curves are computed for a set of pre‐code (i.e., designed only for vertical loads), reinforced concrete building types representative ...

Ricci-Curvature-Enhanced Temporal Graph Convolutional Networks for Traffic Speed Forecasting

open access: yesIEEE Access
Accurate long-horizon traffic speed forecasting is essential for intelligent transportation systems, yet spatiotemporal graph neural networks can suffer from over-squashing when information must traverse topological bottlenecks. We propose Ricci-T-GCN, a

On the equivalence of two curvature conditions for Lorentzian hypersurfaces

open access: yesArab Journal of Mathematical Sciences, 2017
Let n≥3. We show that semi-symmetry and Ricci-semisymmetry conditions are equivalent for any n-dimensional Lorentzian hypersurface in a Lorentzian space form with nonzero curvature.

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.

Eco‐Friendly Preparation of Porous Starch via Water‐Induced Amylose Solubilization

open access: yesPolymers for Advanced Technologies, Volume 37, Issue 5, May 2026.
ABSTRACT Starch is a safe and biocompatible excipient in pharmaceutical formulations. Introducing pores into its granules transforms it into a biodegradable carrier suitable for drug delivery. Various strategies have been developed to induce pore formation, including physical methods (e.g., microwave, ultrasound), chemical methods (e.g., solvent ...

Geometry of Supergravity and the Batalin–Vilkovisky Formulation of the N=1$\mathcal N=1$ Theory in Ten Dimensions

open access: yesFortschritte der Physik, Volume 74, Issue 5, May 2026.
ABSTRACT We provide full details of a BV formulation of N=1$\mathcal N=1$ supergravity in 10 dimensions, to all orders in fermions, built from the generalised geometry description of the theory. In contrast to standard treatments, we introduce neither the degrees of freedom corresponding to orthonormal frames for the metric nor the local Lorentz ...

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 ...

k-Almost Newton-Conformal Ricci Solitons on Hypersurfaces Within Golden Riemannian Manifolds with Constant Golden Sectional Curvature

open access: yesAxioms
The current work establishes the geometrical bearing for hypersurfaces in a Golden Riemannian manifold with constant golden sectional curvature with respect to k-almost Newton-conformal Ricci solitons.

Enhancing Infrastructure Resilience in Service Utilities through Embedding Versatility in System Architecture

open access: yesSystems Research and Behavioral Science, Volume 43, Issue 3, Page 1295-1313, May/June 2026.
ABSTRACT Enhancing infrastructure resilience, a key component of transforming and sustainably developing service utilities, requires a transdisciplinary and systems engineering framework. Addressing vulnerabilities in system architecture offers opportunities for resilience improvements, thereby mitigating the environmental, social, and economic impacts

Untargeted Metabolomics Coupled With Machine Learning Unravels Crop‐Specific Versus Generalized Effects of Biostimulants in Cucumber, Pepper, and Tomato

open access: yesPhysiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT In recent years, agricultural practices have shifted toward sustainability, aiming to reduce the use of agrochemicals and rely more on bio‐based solutions. However, the effectiveness of these latter suffers from inconsistency. Understanding how different crops respond to biostimulants, instead of referring to a specific trial or crop, is a ...
