The maximal subgroups of the classical groups in dimension 13, 14 and 15 [PDF]

open access: yes, 2015
One might easily argue that the Classification of Finite Simple Groups is one of the most important theorems of group theory. Given that any finite group can be deconstructed into its simple composition factors, it is of great importance to have a ...

Thermodynamic limits and performance optimization of nighttime thermoradiative energy conversion systems with non-idealities

open access: yesCase Studies in Thermal Engineering, 2023
To address the challenge of the growing global energy crisis and the greenhouse effect, employing the thermoradiative effect of photodiodes to harvest radiative energy from colder outer space is considered a promising approach for direct nighttime ...

On rings of real valued clopen continuous functions

open access: yesApplied General Topology, 2018
Among variant kinds of strong continuity in the literature, the clopen continuity or cl-supercontinuity (i.e., inverse image of every open set is a union of clopen sets) is considered in this paper.

Mechanical muscle properties and intermuscular coordination in maximal and submaximal cycling: theoretical and practical implications [PDF]

open access: yes, 2014
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel UniversityThe ability of an individual to perform a functional movement is determined by a range of mechanical properties including the force and power producing ...

Sectional representation of Banach modules and their multipliers

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
Let X be a Banach module over the commutative Banach algebra A with maximal ideal space Δ. We show that there is a norm-decreasing representation of X as a space of bounded sections in a Banach bundle π:ℰ→Δ, whose fibers are quotient modules of X.

Maximal ideal space of function algebras [PDF]

open access: yesJournal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1997
AbstractWe present a representation theory for the maximal ideal space of a real function algebra, endowed with the Gelfand topology, using the theory of uniform spaces. Application are given to algebras of differentiable functions in a normęd space, improving and generalizing some known results.

A Note on Some Uniform Algebra Generated by Smooth Functions in the Plane

open access: yesJournal of Function Spaces and Applications, 2012
We determine, via classroom proofs, the maximal ideal space, the Bass stable rank as well as the topological and dense stable rank of the uniform closure of all complex-valued functions continuously differentiable on neighborhoods of a compact planar set

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
