Sensitive Spectral and Temporal–Spatial Characteristic Analysis of Leaf SPAD in Maize Under Variety and Nitrogen Coupling Effects

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
The data processing flow was shown in graphical abstract. The first phase was construction of dataset, including acquisition and inordinate value elimination of spectral data and SPAD of maize leaves. The second phase was the dynamic growth effect analysis of SPAD value of maize leaves at different growth stages and leaf positions.

Clinical Applications of Electrical Conductivity Imaging Using MRI

open access: yesJournal of Magnetic Resonance Imaging, Volume 63, Issue 5, Page 1224-1245, May 2026.
ABSTRACT Magnetic resonance imaging (MRI) has emerged as a noninvasive technique for probing the electrical properties of biological tissues: electrical conductivity and relative permittivity. This review focuses on the electrical conductivity and provides a comprehensive overview of applications across both low‐ and high‐frequency regimes.

Velocity Spectrum Imaging Using Velocity Encoding Preparation Pulses

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2568-2579, May 2026.
ABSTRACT Purpose The goal of this article is to introduce a technique to measure the velocity distribution of water inside each voxel of an MR image. The method is based on the use of motion sensitizing gradients with changing first moment to encode velocity. As such, it is completely non‐invasive and requires no contrast injections.

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 ...

Vector Field‐Based Collision‐Free Navigation in Tunnel‐Like Environments

open access: yesJournal of Field Robotics, Volume 43, Issue 3, Page 2521-2547, May 2026.
ABSTRACT Tunnel‐like environments, renowned for their vast scale, confined spaces, and limited visibility, present significant challenges for autonomous robot navigation. This study addresses the critical issue of guiding robots through such environments while ensuring collision‐free navigation and maintaining a specified safety margin from both tunnel
