Les relations sociales, frein ou moteur de la durabilité
Development paths may include contradictions between the different dimensions of sustainability. This article shows the usefulness of the notion of radius of trust in order to evaluate the contribution of social relationships to sustainability.

Objectives The bony shoulder stability ratio (BSSR) allows for quantification of the bony stabilisers in vivo. We aimed to biomechanically validate the BSSR, determine whether joint incongruence affects the stability ratio (SR) of a shoulder model, and ...

Data‐Driven Distributed Safe Control Design for Multi‐Agent Systems
This paper presents a data‐driven control barrier function (CBF) technique for ensuring safe control of multi‐agent systems (MASs) with uncertain linear dynamics. A data‐driven quadratic programming (QP) optimization is first developed for CBF‐based safe control of single‐agent systems using a nonlinear controller. This approach is then extended to the

The unrolling of the peltate leaves in Syngonium podophyllum is analyzed and quantified (left‐hand side to center). These measurements serve to verify a mathematical model for leaf unrolling based on the model used in Schmidt (2007). An additional formula for obtaining a layer mismatch from a prescribed radius is derived.

On calculation of the stability radius for a minimum spanning tree
We consider a minimum spanning tree problem in the situation where weights of edges are exposed to independent perturbations. We study a quantitative characteristic of stability for a given optimal solutions of the problem.

Hydrogel‐Based Capacitive Sensor Model for Ammonium Monitoring in Aquaculture
Traditional techniques for monitoring aquaculture water quality, particularly ammonium levels, harm fish. This work presents a novel capacitive sensor with an ionic hydrogel transducer to monitor ammonium concentration in real time based on the ammonium‐induced hydrogel dissociation and osmotic pressure. Monitoring aquaculture water quality, especially

The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

The Effect of Rounding in Bump Foil Structure on the Dynamic Performance of Foil Journal Bearings
The performance of air foil journal bearings is closely related to the stiffness of the bump foil. In this paper, the stiffness characteristics of bump foil having a rounding in the structure are investigated and compared with previous models.
