Some Applications of Supra Preopen Sets

open access: yesJournal of Mathematics, 2020
The aim of this work is to define some concepts on supra topological spaces using supra preopen sets and investigate main properties. We started this paper by correcting some results obtained in previous study and presenting further properties of supra ...

The emergence of geometry: a two-dimensional toy model

open access: yes, 2010
We review the similarities between the effective chiral lagrangrian, relevant for low-energy strong interactions, and the Einstein-Hilbert action. We use these analogies to suggest a specific mechanism whereby gravitons would emerge as Goldstone bosons ...

Low-Altitude Reconnection Inflow-Outflow Observations during a 2010 November 3 Solar Eruption [PDF]

open access: yes, 2012
For a solar flare occurring on 2010 November 3, we present observations using several SDO/AIA extreme-ultraviolet (EUV) passbands of an erupting flux rope followed by inflows sweeping into a current sheet region. The inflows are soon followed by outflows

Supra R-homeomorphism in supra topological ordered spaces

open access: yesInternational Journal of Algebra and Statistics, 2017
In this work, The notions of supra R-open sets and and increasing (decreasing, balancing) sets are utilized to initiate some ordered maps namely, x- supra R-continuous, x-supra R-open, x-supra R-closed and x-supra R homeomorphism maps, for x ∈ {I,D,B}. The equivalent conditions for each concept are given and the relationships among them are illustrated

A weak acceleration effect due to residual gravity in a multiply connected universe

open access: yes, 2006
Could cosmic topology imply dark energy? We use a weak field (Newtonian) approximation of gravity and consider the gravitational effect from distant, multiple copies of a large, collapsed (virialised) object today (i.e.

Loss of brain inter-frequency hubs in Alzheimer's disease [PDF]

open access: yes, 2017
Alzheimer's disease (AD) causes alterations of brain network structure and function. The latter consists of connectivity changes between oscillatory processes at different frequency channels. We proposed a multi-layer network approach to analyze multiple-

Supra b Maps via Topological Ordered Spaces

open access: yesEuropean Journal of Pure and Applied Mathematics, 2019
The authors utilize the notions of increasing, decreasing and balancing supra $b$-open sets to introduce and study several types of supra continuous, supra open, supra closed and supra homeomorphism maps in supra topological ordered spaces. They give the equivalent conditions for each one of these notions and illustrate the relationships among them ...

Persistently Increased Expression of PKMzeta and Unbiased Gene Expression Profiles Identify Hippocampal Molecular Traces of a Long‐Term Active Place Avoidance Memory and “Shadow” Proteins

open access: yesAdvanced Science, EarlyView.
Protein complexes like KIBRA‐PKMζ are crucial for maintaining memories, forming month‐long protein traces in memory‐tagged neurons, but conventional RNA‐seq analysis fails to detect their transcript changes, leaving memory molecules undetected in the shadows of abundantly‐expressed genes.

The Inhuman Overhang: On Differential Heterogenesis and Multi-Scalar Modeling [PDF]

open access: yes, 2020
As a philosophical paradigm, differential heterogenesis offers us a novel descriptive vantage with which to inscribe Deleuze’s virtuality within the terrain of “differential becoming,” conjugating “pure saliences” so as to parse economies, microhistories,
