Rocking-Sliding of a Rigid Block: Friction Influence on Free Motion
Engineering Transactions, 2015 Many technical problems involve contact and impact between bodies. The contact problem is locally characterized by normal and shear forces; this contact may represent different types of phenomena such as rolling, sliding, impact and shock, unilateral ...

Some remarks on the damage unilateral effect modelling for microcracked materials [PDF]
, 2002 This study deals with the macroscopic modelling of the mechanical behaviour of microcracked materials and particularly with the unilateral aspect of such damage which leads, at the closure of microcracks, to a partial damage deactivation.

, 2013 In this paper, beam models accounting for non-linear elastic bimodular constitutive behavior and frictionless unilateral contact conditions are rationally deduced from three-dimensional elasticity by means of a variational constrained approach ...

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Chronic rhinosinusitis with nasal polyp (CRSwNP) is a heterogeneous Type 2 inflammatory disease characterized by enhanced eosinophilic infiltration. Both innate and adaptive immunity are involved in the onset and progression of CRSwNP.

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Healing dynamics after anterior skull base (ASB) reconstruction following transnasal endoscopic surgery (TES) for sinonasal malignancies remain poorly characterized. This study aimed to describe the postoperative healing process, quantify time to healing, identify factors influencing healing, and assess radiologic evolution over ...

An Elastic Frictional Contact Problem with Unilateral Constraint
Mediterranean Journal of Mathematics, 2018 We consider a mathematical model which describes the equilibrium of an elastic body in contact with two obstacles. We derive its weak formulation which is in a form of an elliptic quasi-variational inequality for the displacement field. Then, under a smallness assumption, we establish the existence of a unique weak solution to the problem.

Animal Models and Experimental Medicine, EarlyView.D‐limonene supplementation enhances testicular recovery following orchiopexy in a rat model of bilateral cryptorchidism. Treatment with D‐limonene reduces oxidative stress (↓MDA, ↑SOD, ↑GPx, ↑TAC), downregulates pro‐apoptotic proteins (↓TNF‐α, ↓BAX, ↓Caspase‐3), and upregulates anti‐apoptotic Bcl‐2 expression.

Establishment and characterization of mouse lymph node fibrosis models
Animal Models and Experimental Medicine, EarlyView.The design of the entire paper. Schematic illustration of four strategies for establishing mouse lymph node (LN) fibrosis models. The study further compares their fibrotic remodeling patterns and immune alterations. Abstract Background Lymph node (LN) fibrosis occurs in a variety of pathological conditions, including HIV infection, obesity, cancer, and

Annals of Neurology, EarlyView.Objective Memory impairment is a frequent comorbidity of focal epilepsy, incompletely explained by seizure frequency or structural pathology. Ictal and postictal hippocampal dysfunction disrupt memory processes, but their cumulative impact remains poorly quantified.
