¿Váscones o Wascónes? Acerca del Ducado de Cantabria y la fundación de ciudades en el norte peninsular en época visigoda

open access: yesE-Spania, 2013
The Chronicles of Juan de Biclaro and Isidore of Seville news Visigothic foundation of two cities in Vasconia: Victoriacum and Ologicus. Traditionally identified with a point near Vitoria, the first, and the villa of Olite in Navarra, the second, this ...

Entropy zero area preserving diffeomorphisms of $S^2$

open access: yes, 2012
In this paper we formulate and prove a structure theorem for area preserving diffeomorphisms of genus zero surfaces with zero entropy. As an application we relate the existence of faithful actions of a finite index subgroup of the mapping class group of ...

Spin‐Crossover Confinement in Mesoporous Matrices Enables Tunable Porosity for Molecular Sensing

open access: yesAdvanced Materials Interfaces, EarlyView.
The integration of hierarchically organized porous frameworks with spin‐crossover nanodomains enables cooperative interactions across multiple length scales. This hybrid design merges dynamic molecular switching with tunable porosity, yielding materials whose structural and functional responses are actively modulated by confinement and guest uptake ...

An elementary proof of Franks' lemma for geodesic flows [PDF]

open access: yes, 2013
Given a Riemannian manifold $(M,g)$ and a geodesic $\gamma$, the perpendicular part of the derivative of the geodesic flow $\phi_g^t: SM \rightarrow SM$ along $\gamma$ is a linear symplectic map. We give an elementary proof of the following Franks' lemma,

Gold Nanorods in Cardiac Millitissues: Assessing Mechanical and Contractile Dynamics in a Living Engineering Myocardium Model

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a novel platform for assessing the active mechanical behavior of living cardiac microbundles through localized nanoindentation, integrated with temperature regulation and dual‐camera imaging systems. The developed system enables quantitative evaluation of dynamic micromechanics in engineered cardiac tissues in vitro, offering ...

Identification of a change in climate state using regional flood data [PDF]

open access: yesHydrology and Earth System Sciences, 2002
Flood frequency analysis typically assumes that annual floods arise from a single distribution and are independent. However, there is significant evidence for the existence of persistent climate modes. Timescales associated with climate variability range

A meta‐review of “lifestyle psychiatry”: the role of exercise, smoking, diet and sleep in the prevention and treatment of mental disorders

open access: yesWorld Psychiatry, 2020
There is increasing academic and clinical interest in how “lifestyle factors” traditionally associated with physical health may also relate to mental health and psychological well‐being. In response, international and national health bodies are producing

Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing

open access: yesAdvanced Materials Technologies, EarlyView.
Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the

The Politics of Stalemate: Local Power, U.S. Military Bases, and the Japanese Courts

open access: yesThe ASIANetwork Exchange: A Journal for Asian Studies in the Liberal Arts, 2017
The continued controversy over the presence of American bases in Okinawa has once again raised the question of whether the issue will ultimately be resolved by the Japanese courts.

The rationality of history and the history of rationality: Menachem Fisch on the analytic idealist predicament

open access: yesOpen Philosophy, 2020
Two essential Kantian insights are the significance for rationality of the capacity for criticism and the limits of cognition, discovered when criticism is pursued methodically, that are due to the perspectival character of the human standpoint.
