A Methodological Framework for Structural Reliability Assessment of Marine Structural Elements

open access: yesJournal of Marine Science and Engineering, 2023
The aim of this paper is to provide a robust framework to assist researchers in deciding which methods to use, depending on the problem at hand, in order to estimate the probability of failure of marine structural parts that are subjected to variable ...

Ultrasonic Rainbow: A Meta‐Transducer for Frequency‐Selective Elastic Wave Control via Dithering‐Based Wavenumber Tuning

open access: yesAdvanced Intelligent Systems, EarlyView.
A piezoelectric meta‐transducer generates an ultrasonic rainbow, steering guided elastic waves to different angles according to frequency. A dithering‐based binary electrode design enables a closer realization of the target wavenumber filter, improving directional purity and suppressing unwanted lobes. Numerical and experimental validation demonstrates

Diffusion MRI and α‐Synuclein Seed Amplification Status in Parkinson's Disease

open access: yesAnnals of Neurology, EarlyView.
Objective Positive α‐synuclein seed amplification assay (SAA) is a biomarker found in most people with Parkinson's disease (PD). We explored if free‐water (FW) imaging detects microstructural differences in the brains of patients with early PD with SAA+ or SAA– status.

Design and Validation of a Low-Cost Structural Health Monitoring System for Dynamic Characterization of Structures

open access: yesApplied Sciences, 2022
Structural Health Monitoring (SHM) is essential to identifying problems that may cause human and material losses produced by disastrous and unexpected structural failures. The dynamic characterization of civil structures adopting SHM systems provides, at

Early stages of tooth development in the harbor porpoise Phocoena phocoena

open access: yesThe Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

Single‐Cell Level Characterization of B Cell Depletion and Repopulation Following Rituximab in Systemic Lupus Erythematosus

open access: yesArthritis &Rheumatology, EarlyView.
Objective Rituximab, a CD20+ B cell depletion therapy, is frequently used to treat systemic lupus erythematosus (SLE). However, variability in patient response highlights the need for a deeper understanding of the underlying immune cell dynamics of B cell depletion and repopulation.

Assessment of Sensor Technologies for Aircraft SHM Systems

open access: yesFatigue of Aircraft Structures, 2014
SHM is a monitoring system which uses sensors, actuators and data transmission, acquisition and analysis, permanently integrated with the inspected object. The objective of SHM is to detect, localize, identify and predict development of fatigue fractures,

The role of IgM anti‐acetylated protein antibodies and B cells in the origin of anti‐modified protein autoimmunity in rheumatoid arthritis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Rheumatoid arthritis (RA) is characterized by anti‐modified protein antibodies (AMPAs), including anti‐citrullinated (ACPA), anti‐carbamylated (anti‐CarP), and anti‐acetylated (AAPA) protein antibodies. In contrast to other AMPAs, AAPA IgM is found in healthy individuals, raising questions about its role in early immune responses.
