Multi‐Scaled Cellulosic Nanonetworks from Tunicates

Advanced Functional Materials, Volume 35, Issue 30, July 24, 2025.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–

An engineer, for what? On the different invitations a university extends to its students to acquire a professional identity

Journal of Engineering Education, Volume 114, Issue 3, July 2025.
Abstract Background The inquiry into the ultimate purpose of engineering practice and into how engineering students develop a professional identity aligned with it is a matter of great ethical and political importance. Engineering education programs play a key role here by interpellating or inviting students, both in explicit and implicit ways, to ...

Chemostat models with Monod and Haldane consumption functions and random environmental fluctuations

Mathematical Methods in the Applied Sciences, Volume 48, Issue 7, Page 7412-7431, 15 May 2025.
In this paper, we study the asymptotic dynamics of two chemostat models with random environmental fluctuations modeled by means of real noise, where different consumption functions for the consumer species (Monod and Haldane) are taking into account. For each model, our main goal is to investigate the existence of deterministic attracting sets.

Generalized finite difference method applied to solve seismic wave propagation problems. Examples of 3D simulations

Mathematical Methods in the Applied Sciences, Volume 48, Issue 7, Page 7706-7726, 15 May 2025.
The simulation of seismic wave propagation generally requires dealing with complex tridimensional geometries that are irregular in shape and have non‐uniform properties, features that make the application of the generalized finite difference method in this field interesting. This work continues the extensive developments by the research team focused on

Transport and Depositional Processes of Neogene Pumice Fragments in a Distal Fluvial System of the Northern Patagonian Foreland (Argentina)

Basin Research, Volume 37, Issue 3, May/June 2025.
In this work we analyse the origin, transport, and deposition processes of pumice fragments up to 30 cm in size, deposited in the Northern Patagonian Foreland more than 200 km from the Andean volcanic arc. ABSTRACT There are numerous studies analysing volcaniclastic supply to continental environments in distal areas from source volcanoes.

Systematic and taxonomic revision of the genus Austrocactus (Cactaceae) based on morphology and genome wide SNP‐data

TAXON, Volume 74, Issue 2, Page 386-416, April 2025.
Abstract The post‐Miocene climatic history of arid environments in South America has been identified as a key driver of dispersal and diversification, particularly among plant groups such as Cactaceae. Despite their iconic status, many cactus genera remain poorly understood, and comprehensive taxonomic and systematic revisions using morphological and ...

Discussing trust and resilience: The need for a healthy dose of distrust 探讨信任与复原力——适度不信任的必要性 Debatir sobre confianza y resiliencia: la necesidad de una buena dosis de desconfianza

Risk, Hazards &Crisis in Public Policy, Volume 16, Issue 1, March 2025.
Abstract How are trust and reslience related? There is a lack of conceptual discussions. This paper analyzes trust and resilience with respect to the system of critical infrastructures and engineers working on critical infrastructure resilience. The results are three findings based on the assumption that resilience and trust are mechanisms to cope with
