Some novel mathematical results on the existence and uniqueness of generalized Caputo-type initial value problems with delay

open access: yesAIMS Mathematics, 2022
In this article, we propose some novel results on the existence and uniqueness of generalized Caputo-type initial value problems with delay by using fixed point theory.

THE EXISTENCE OF GOD

open access: yesPhilosophical Books, 1965
Abstract This book assesses the worth of arguments for and against the existence of God. Evidence confirms (makes more probable) a hypothesis that explains that (1) given the hypothesis, the evidence is to be expected, i.e. the hypothesis makes the evidence probable, (2) the evidence is not otherwise to be expected, (3) the hypothesis is

Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells

open access: yesFEBS Letters, EarlyView.
Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...

On well posed impulsive boundary value problems for p(t)-Laplacian's

open access: yesMathematical Modelling and Analysis, 2013
In this paper we investigate via variational methods and critical point theory the existence of solutions, uniqueness and continuous dependence on parameters to impulsive problems with a p(t)-Laplacian and Dirichlet boundary value conditions.

Self-realizing a lived existence in service of emancipation: Tsenay Serequeberhan’s activist hermeneutics

open access: yesActa Academica, 2023
Through his own activistic hermeneutics, Sereque­ berhan crafts a philosophy which allows African(a) persons pathways to self­-realization and self­-eman­cipation from Western cultural imperialism.

Kirchhoff equations in generalized Gevrey spaces: local existence, global existence, uniqueness [PDF]

open access: yes, 2009
In this note we present some recent results for Kirchhoff equations in generalized Gevrey spaces. We show that these spaces are the natural framework where classical results can be unified and extended.

This elusive objective existence

open access: yes, 2004
Zurek's existential interpretation of quantum mechanics suffers from three classical prejudices, including the belief that space and time are intrinsically and infinitely differentiated. They compel him to relativize the concept of objective existence in

Gunky time and indeterminate existence [PDF]

open access: yes, 2017
The paper criticizes an argument recently presented by Ross Cameron. The argument purports to show that, if time is gunky (that is, if there are no time atoms), and if changes in existence are underwritten by events of coming to be, then there are cases ...

Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

On the Solutions of the Higher Order Fractional Differential Equations of Riesz Space Derivative with Anti-Periodic Boundary Conditions

open access: yesCommunications in Advanced Mathematical Sciences, 2021
We present existence and uniqueness results for a class of higher order anti-periodic fractional boundary value problems with Riesz space derivative which is two-sided fractional operator.
