Modelling and in vitro testing of the HIV-1 Nef fitness landscape. [PDF]

open access: yes, 2019
An effective vaccine is urgently required to curb the HIV-1 epidemic. We have previously described an approach to model the fitness landscape of several HIV-1 proteins, and have validated the results against experimental and clinical data.

Fitness functions for RNA structure design

open access: yesNucleic Acids Research, 2022
Abstract An RNA design algorithm takes a target RNA structure and finds a sequence that folds into that structure. This is fundamentally important for engineering therapeutics using RNA. Computational RNA design algorithms are guided by fitness functions, but not much research has been done on the merits of these functions.

A function fitting method

open access: yesJournal of Applied Analysis, 2020
Abstract In this article, we describe a function fitting method that has potential applications in machine learning and also prove relevant theorems. The described function fitting method is a convex minimization problem which can be solved using a gradient descent algorithm.

Visual function and fitness to drive [PDF]

open access: yesBritish Medical Bulletin, 2008
Driving is recognized to be a visually intensive task and accordingly there is a legal minimum standard of vision required for all motorists. The purpose of this paper is to review the current United Kingdom (UK) visual requirements for driving and discuss the evidence base behind these legal rules.

Arm-crank training improves postural stability and physical functioning in older people [PDF]

open access: yes, 2018
Background: Arm crank ergometry (ACE) has been shown to elicit marked improvements in lower body exercise capacity among older individuals. It is currently unknown whether ACE is effective in alleviating functional consequences of aging, such as balance ...
