La lògica de l'espai construït al Sudest de la Península Ibèrica durant l'Argar (2200 - 1550 cal ANE) : una aproximació metodològica [PDF]

, 2014
L'estudi de l'arquitectura domèstica emprada per les societats del sud-est de la península Ibèrica durant l'Edat del Bronze requereix una sistematització de coneixements per esbrinar, en primer lloc, de quina manera construïen i sobretot quan temps ...

Fluorescent Probe for δ‐Cyclodextrin Enables Guest Encapsulation Studies via an Indicator Displacement Assay

ChemistryEurope, Volume 3, Issue 3, May 2025.
A molecular probe that partially unfolds and exhibits fluorescence enhancement upon binding to δ‐cyclodextrin (δ‐CD) is presented. Its implementation in a fluorescence indicator displacement assay to test the binding of various guest to δ‐CD is demonstrated.

Grups i la paradoxa de Banach-Tarski [PDF]

, 2009
En aquest article exposarem una demostració de la paradoxa de Banach– Tarski per a R3, així com del fet que la paradoxa no és possible a R2. Ambdues demostracions tenen un punt crucial on intervenen els grups discrets, especialment al voltant del ...

Stochastic thermodynamics for biological functions

Quantitative Biology, Volume 13, Issue 1, March 2025.
Abstract Living systems operate within physical constraints imposed by nonequilibrium thermodynamics. This review explores recent advancements in applying these principles to understand the fundamental limits of biological functions. We introduce the framework of stochastic thermodynamics and its recent developments, followed by its application to ...

How Does Trade Policy Uncertainty Affects Innovative Behavior in Export‐Oriented Enterprise: Evidence From Listed Export Companies of Chinese

Discrete Dynamics in Nature and Society, Volume 2025, Issue 1, 2025.
This paper discusses the impact of trade policy uncertainty (TPU) on innovative behavior in export‐oriented enterprises using data of nonfinancial Chinese A‐share listed companies from 2007 to 2021. TPU index is constructed using a tariff measurement method and a text mining method after China’s accession to the WTO.

A Concrete Resistivity Method Based on a Simple Measuring Cell for Onsite Corrosion Monitoring: Study on Concrete Under Varying Conditions

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
Concrete resistivity (ρ) is commonly monitored in situ using sensors based on the rebar‐disc (RDM) or four‐electrode (FEM) methods. This study validates, for the first time in reinforced concrete, an innovative corrosion sensor approach (CSA) previously tested only in simulated pore solutions.

Numerical investigations on the influence of the nominal hole clearance on the plate resilience of high strength preloaded bolted joints Numerische Untersuchungen zum Einfluss des Nennlochspiels auf die Plattennachgiebigkeit von hochfest vorgespannten Schraubenverbindungen

Materialwissenschaft und Werkstofftechnik, Volume 55, Issue 12, Page 1687-1706, December 2024.
Zur Erhöhung des Nennlochspiels kommen in geschraubten Verbindungen häufig Langlöcher zum Einsatz. Um dennoch eine reibschlüssige Tragwirkung gewährleisten zu können, muss u. a. ein Hineinziehen der Scheiben in das Langloch vermieden werden. Slotted holes are often used in bolted connections to increase the nominal hole clearance.
