Second-order kinematic invariants for the design of compliant auxetic symmetrical structures

Auxetic structures have great potential in modern engineering, and their design represents an emerging field in industrial applications. The accurate synthesis of the elements of such structures requires multidisciplinary approaches that combine kinematics and structural mechanics. Design methodologies are often based on complex time-consuming numerical methods and with considerable computational burden for exploring a large set of alternatives. The aim of the present work is to propose a nov...

Bidimensional fuzzy-based propagation of interdependent uncertainty in pseudo-rigid multibody models of spur gears

In gear analysis, pseudo-rigid multibody models offer a strategic compromise between accuracy and computational efficiency. However, these models are characterized by parameters affected by epistemic uncertainty, which is often neglected. This work proposes a bidimensional fuzzy representation to quantify such uncertainty while explicitly accounting for physical correlations between key parameters, such as joint positions and elastic element values. The approach is applied to both quasi-stati...

Influence of profile modifications on spur gear sliding power losses: an integrated approach with advanced mesh stiffness and partial EHL

This study investigates the impact of profile modifications on sliding power loss in cylindrical gears, a critical aspect of gear efficiency. Profile modifications are widely adopted in gear design to improve load distribution, mitigate noise and vibrations, and enhance durability. Although much of the existing research has focused on their dynamic benefits, such as reducing noise and vibration, their influence on gear meshing efficiency, particularly sliding power losses, remains insufficien...

In memoriam: Professor Ettore Pennestrì (1957–2024): a life dedicated to science, mentorship, and the art of kinematics

This paper commemorates the first anniversary of the passing of Professor Ettore Pennestrì (1957–2024), a distinguished scholar in Mechanism and Machine Science, who left an indelible mark on the scientific and engineering community. Pennestrì made pioneering contributions across diverse areas including theoretical kinematics, mechanism synthesis, gear analysis, multibody dynamics, compliant mechanisms, biomechanics, and vibration dampers. He was renowned for his interdisciplinary approach, s...

Report of the Italian Cohort with Activated Phosphoinositide 3-Kinase δ Syndrome in the Target Therapy Era

Background: Activated Phosphoinositide 3-Kinase (PI3K) δ Syndrome (APDS), an inborn error of immunity due to upregulation of the PI3K pathway, leads to recurrent infections and immune dysregulation (lymphoproliferation and autoimmunity). Methods: Clinical and genetic data of 28 APDS patients from 25 unrelated families were collected from fifteen Italian centers. Results: Patients were genetically confirmed with APDS-1 (n = 20) or APDS-2 (n = 8), with pathogenic mutations in the PIK3CD or PIK3...
