Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Achieving Ultra‐Low Megahertz Loss in Nanocrystalline Magnetic Powder Cores via Alloy Design and a Self‐Healing Organic–Inorganic‐Derived Hybrid Insulating Layer

open access: yesAdvanced Chemical Engineering, Volume 1, Issue 2, December 2026.
A novel self‐healing FePO4/B2O3/epoxy hybrid insulating layer is designed for high‐frequency Fe‐based nanocrystalline magnetic powder cores. During 530°C annealing, the low‐melting‐point B2O3 softens, flowing into micro‐cracks formed within the brittle FePO4 framework during cold pressing. This in situ gap‐filling mechanism effectively suppresses inter‐

Multi‐Vendor and Multi‐Site Characterization of 13C Coils for Clinical Studies

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 6, Page 2885-2893, December 2026.
ABSTRACT Purpose Due to the inherently low signal‐to‐noise ratio (SNR) domain for 13C imaging, optimal coil performance is essential to maximize data quality. Quality control (QC) for 13C coils employed in magnetic resonance spectroscopy (MRS) is of paramount importance.

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 17, Page 6124-6153, 10 December 2026.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

Quantitative Chemical Exchange Saturation Transfer Imaging With Golden‐Angle Radial k‐Space Sampling and Locally Low‐Rank Reconstruction

open access: yesNMR in Biomedicine, Volume 39, Issue 12, December 2026.
A radial CEST‐MR Fingerprinting method is demonstrated that avoids EPI distortion using low‐rank reconstruction and neural network quantification. It produced accurate 3D brain CEST maps in 11 min, with simulation errors below 14%, strong agreement with conventional fitting, high reproducibility (ICC up to 0.92), and limited motion‐related errors.

Simulation‐Based Analysis of Insert Pull‐Out in Nickel‐Polyurethane Hybrid Foams Using CT‐Derived Geometries

open access: yesAdvanced Engineering Materials, Volume 28, Issue 21, 4 November 2026.
CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.
