White Matter and Perivascular Imaging Changes in Alzheimer's Disease and Cerebral Amyloid Angiopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Peak‐width of skeletonized mean diffusivity (PSMD) and diffusion tensor imaging–analysis along the perivascular space (DTI‐ALPS), reflecting white matter integrity and glymphatic function, are altered in Alzheimer's disease (AD).

Short‐Term Response to Biologic Therapy in Psoriatic Arthritis Is Not Influenced by Disease Duration at Initiation of Therapy

Arthritis Care &Research, EarlyView.
Objective We aimed to determine whether the short‐term response to biologics in biologic‐naive psoriatic arthritis (PsA) is better in patients initiating biologic treatment early in the disease course. Methods Patients with PsA who started on biologic therapy from the year 2000 to 2025 were included for analysis.

Flexural Behavior of 3D‐Printed Porous Bouligand‐Structured Polymers: Influence of Pitch Angle and Porosity

Advanced Engineering Materials, EarlyView.
This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight

Analysis of Grading Ring Design Parameters and Heat Sink Numbers Effect on Voltage Distribution and Leakage Current in Metal Oxide Surge Arrester

Iranian Journal of Electrical and Electronic Engineering, 2014
Metal oxide surge arresters (ZNO) are used widely in power system to protect equipments from over voltages. Non uniform potential distribution leads to the depressed service life and low safe reliability, so grading ring is applied on HV surge arrester ...

Time-Delay Estimation for Partial Discharge in Arresters Using Joint Denoising and HB-Weighted Cross-Correlation

Energies
Partial discharge (PD) detection is a crucial means for the early warning of incipient insulation defects in arresters. However, under strong electromagnetic interference and background noise, PD signals are prone to distortion, making it difficult to ...

Distinct Microstructural Characteristic Lengths Defining Notch Fatigue Crack Initiation and Propagation, and Defect Tolerance in Advanced Steels

Advanced Engineering Materials, EarlyView.
Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...
