Topos theory and consistent histories: The internal logic of the set of all consistent sets [PDF]

open access: yesInternational Journal of Theoretical Physics, 1997
A major problem in the consistent-histories approach to quantum theory is contending with the potentially large number of consistent sets of history propositions. One possibility is to find a scheme in which a unique set is selected in some way. However, in this paper we consider the alternative approach in which all consistent sets are kept, leading ...

Submartingalas finitas, teoremas de convergencia y métodos no standard

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2012
Se examinan dos teoremas clásicos de convergencia de submartingalas en tiempo discreto, los de convergencia casi segura y en L^1, usando los métodos del análisis no standard. Se realiza para ello un estudio previo sobre las submartingalas finitas.

Evaluating investments in advanced manufacturing technology: A fuzzy set theory approach [PDF]

open access: yes, 2001
In this paper, a model for the evaluation of investments in advanced manufacturing technology is developed. Many authors have called for an integration of financial and non-financial factors in such evaluations and this paper demonstrates that it is ...

Second order logic or set theory? [PDF]

open access: yes, 2012
We try to answer the question which is the “right” foundation of mathematics, second order logic or set theory. Since the former is usually thought of as a formal language and the latter as a first order theory, we have to rephrase the question.

The method of averaging and functional differential equations with delay

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We present a natural extension of the method of averaging to fast oscillating functional differential equations with delay. Unlike the usual approach where the analysis is kept in an infinite-dimensional Banach space, our analysis is achieved in ℝn.

What internal set theory knows about standard sets

open access: yes, 1997
We characterize those standard models M of ZFC which are embeddable, as the class of all standard sets, in a model of internal set theory IST. The necessary and sufficient condition is that 1) there is a wellordering < of M which does not destroy the ZFC schemata, and 2) the truth relation for (M,

Fluctuations in the Ginzburg–Landau Theory of Dark Energy: Internal (In)consistencies in the Planck Data Set

open access: yesThe Astrophysical Journal, 2022
Abstract In this work, predictions of the Ginzburg–Landau theory of dark energy (GLT) for cosmic microwave background (CMB) lensing are studied. We find that the time and scale dependence of the dark energy fluctuations in this semiphenomenological model is favored by data in several ways.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
