Leibniz entre logicisme, formalisme et intuitionnisme ?

open access: yesPhilosophia Scientiæ
Leibniz has often been presented as one of the precursors of logicism or formalism but more rarely a precursor of intuitionism. He was a staunch defender of the Tertium non datur, reasoning in forma and blind thought, so at first glance he appears far ...

O Platonismo de Russell na metafísica e na matemática

open access: yesKriterion, 2005
Neste artigo, analiso o surgimento e a superação do Platonismo em B. Russell, tanto na sua filosofia da matemática como na sua metafísica. Começo por explicitar os argumentos que levaram Russell a aderir ao chamado "Platonismo Proposicional" - posição ...

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

La Fundamentación Filosófica de los Principios No-Empíricos de Investigación

open access: yesPrincipia: An International Journal of Epistemology, 2004
Non-empirical principles have always been a subject of interest of philoso-phers. Authors from different times and traditions agree that principles such as analogy or simplicity are present in the scientific practice.

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

open access: yesAdvanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Ludwig Wittgenstein e i fondamenti della matematica. Quattro studi: Cantor, Dedekind, il Logicismo, la scoperta in matematica

open access: yesNóema, 2013
La critica che Ludwig Wittgenstein muove ai presupposti filosofici del dibattito sui fondamenti della matematica si estende oltre le tematiche specifiche di tale dibattito ed investe un’intera tradizione di pensiero. Dietro alle argomentazioni di Frege e

Embedded Ferroelectric Nanoclusters Can Drive Polarization Reversal in a Non‐Ferroelectric Polar Film via the Proximity Effect

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

Gilson on Dogmatism [PDF]

open access: yesStudia Gilsoniana, 2016
The article aims at uncovering reasons why philosophy may become conducive to dogmatism which inevitably leads to the failure of philosophy. In the light of Gilson’s considerations contained in his The Unity of Philosophical Experience, the author ...

La naturaleza de la Matemática, sus concepciones y su influencia en el salón de clase

open access: yesEducación y Ciencia, 2011
Aunque en las últimas dos décadas la situación tiende a cambiar, históricamente se ha tenido la creencia de que para enseñar matemáticas sólo se requiere el buen dominio de los temas, sin tener en cuenta que implícitamente hay una actitud frente a la ...

Monolithic Oxidation Enables Ultrathin Vertically Graded Tantalum Oxide for Low‐Voltage, Low‐Variability Memristive Switching

open access: yesAdvanced Functional Materials, EarlyView.
Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.
