On the Existence and Uniqueness of the Scientific Method. [PDF]
Biol Theory, 2014 The ultimate utility of science is widely agreed upon: the comprehension of reality. But there is much controversy about what scientific understanding actually means, and how we should proceed in order to gain new scientific understanding. Is there a method for acquiring new scientific knowledge? Is this method unique and universal?

Existence and uniqueness of Bowen-York Trumpets [PDF]
Classical and Quantum Gravity, 2011 We prove the existence of initial data sets which possess an asymptotically flat and an asymptotically cylindrical end. Such geometries are known as trumpets in the community of numerical relativists.Comment: This corresponds to the published version in ...

Existence and uniqueness for a semilinear sixth-order ODE
Electronic Journal of Qualitative Theory of Differential Equations, 2022 By using variational methods and maximum principles we discuss the existence, uniqueness and multiplicity of solutions for a semilinear sixth-order ODE. The main difference between our work and other related papers is that we treat a general case and we

Straightening: existence, uniqueness and stability [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 Abstract One of the least studied universal deformations of incompressible nonlinear elasticity, namely the straightening of a sector of a circular cylinder into a rectangular block, is revisited here and, in particular, issues of existence and stability are addressed.

Existence and Uniqueness of Algebraic Closures
Formalized Mathematics, 2022 Summary This is the second part of a two-part article formalizing existence and uniqueness of algebraic closures, using the Mizar [2], [1] formalism. Our proof follows Artin’s classical one as presented by Lang in [3]. In the first part we proved that for a given field F there exists a field extension E such that every non-constant ...

A Malaria Status Model: The Perspective of Mittag-Leffler Function with Stochastic Component
Communication in Biomathematical Sciences, 2022 Malaria continues to affect many individuals irrespective of the status or class particularly in Sub-Saharan Africa. In this work, an existing malaria status classical model is studied in fractionalized perspective.

Fractional stochastic modelling of monkeypox dynamics
Results in Control and Optimization, 2023 Monkeypox virus is primarily transferred to humans via wild animals including rodents and more often the transmission ensues between humans to humans. This disease has been neglected in the past and little effort has been made by research to study the ...
