AIMS MathematicsIn this present paper, we introduce graphical Branciari $ \aleph $-metric space and prove the fixed point theorem for $ \varOmega $-$ \mathcal{Q} $-contraction on complete graphical Branciari $ \aleph $ -metric spaces.

Los manuscritos de Borges: « Imaginar una realidad más compleja que la declarada al lector »
Cuadernos LIRICO, 2012 This article proposes a summary of the possibilities for studying Borges’ manuscripts, while at the same time describing a number of them, in particular those of the short stories in Ficcionesand El Aleph.

Statistics in Medicine, Volume 45, Issue 1-2, January 2026.ABSTRACT Causal variable selection in time‐varying treatment settings is challenging due to evolving confounding effects. Existing methods mainly focus on time‐fixed exposures and are not directly applicable to time‐varying scenarios. We propose a novel two‐step procedure for variable selection when modeling the treatment probability at each time point.

Where Mathematical Symbols Come From
Topics in Cognitive Science, Volume 18, Issue 1, Page 169-186, January 2026.Abstract There is a sense in which the symbols used in mathematical expressions and formulas are arbitrary. After all, arithmetic would be no different if we would replace the symbols ‘+$+$’ or ‘8’ by different symbols. Nevertheless, the shape of many mathematical symbols is in fact well motivated in practice.

Abnormalities of Dopamine D Receptor Signaling in the Diseased Brain
Journal of Central Nervous System Disease, 2017 Dopamine D 3 receptors (D 3 R) modulate neuronal activity in several brain regions including cortex, striatum, cerebellum, and hippocampus. A growing body of evidence suggests that aberrant D 3 R signaling contributes to multiple brain diseases, such as ...

Beyond the Hodge theorem: Curl and asymmetric pseudodifferential projections
Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.Abstract We develop a new approach to the study of spectral asymmetry. Working with the operator curl:=∗d$\operatorname{curl}:={*}\mathrm{d}$ on a connected oriented closed Riemannian 3‐manifold, we construct, by means of microlocal analysis, the asymmetry operator — a scalar pseudodifferential operator of order −3$-3$.

The Aleph Zero or Zero Dichotomy [PDF]
, 2006 The Aleph Zero or Zero Dichotomy is a strong version of Zeno's Dichotomy II which being entirely derived from the topological successiveness of the w-order comes to the same Zeno's ...

A Brief Note on Supercooled Glacial Deep Waters
Paleoceanography and Paleoclimatology, Volume 40, Issue 12, December 2025.Abstract According to hydrographic profiles, approximately 2%–5% of the present‐day deep Southern Ocean contains supercooled waters that are below the freezing point. Which role these supercooled waters may have played under glacial conditions is an open question.

Revista Técnica de la Facultad de Ingeniería, 2011 In this paper we define the ";aleph"; partial derivative through an adequate generalization of the usual concept of. finite increment. The main properties of this operator are also established. This derivative extends the classical partial derivative in
