On the relationship between nucleotide hydrolysis and microtubule assembly : Studies with a GTP-regenerating system
(1987)The assembly of pure tubulin dimer has been studied in two buffer systems (containing low and high glycerol/Mg), using a regeneration system protocol to assess the amount of GDP-tubulin in the assembling polymer. For both ... -
On the representation of time in interaction
(University of Hertfordshire, 1999)The growth in interactive, distributed and multimedia systems and particularly the explosion in use of the World Wide Web means that the concept of time is being recognised as of increasing importance in systems which are ... -
On the shape of the mass-function of dense clumps in the Hi-GAL fields . I : Spectral energy distribution determination and global properties of the mass-functions
(2013-03-01)Context. Stars form in dense, dusty clumps of molecular clouds, but little is known about their origin and evolution. In particular, the relationship between the mass distribution of these clumps (also known as the clump ... -
On the shape of the mass-function of dense clumps in the Hi-GAL fields II : Using Bayesian inference to study the clump mass function
(2014-04)Context. Stars form in dense, dusty clumps of molecular clouds, but little is known about their origin, their evolution, and their detailed physical properties. In particular, the relationship between the mass distribution ... -
On the skeleton of a finite transformation semigroup
(2010)There are many ways to construct hierarchical decompositions of transformation semigroups. The holonomy algorithm is especially suitable for computational implementations and it is used in our software package. The structure ... -
On the spatial distributions of stars and gas in numerical simulations of molecular clouds
(2015-08-21)We compare the spatial distribution of stars which form in hydrodynamical simulations to the spatial distribution of the gas, using the Q -parameter. The Q-parameter enables a self-consistent comparison between the stars ... -
On the spectral depolarisation and lidar ratio of mineral dust provided in the AERONET version 3 inversion product
(2018-09-04)Knowledge of the particle lidar ratio (Sγ) and the particle linear depolarisation ratio (δγ) for different aerosol types allows for aerosol typing and aerosol-Type separation in lidar measurements. Reference values generally ... -
On the time to ruin for a dependent delayed capital injection risk model
(2019-07-01)In this paper, we propose a generalisation to the Cramér–Lundberg risk model, by allowing for a delayed receipt of the required capital injections whenever the surplus of an insurance firm is negative. Delayed capital ... -
On the turbulent flow models in modelling of omni-flow wind turbine
(2014-10)The computational fluid dynamics (CFD) has a wide application in the wind energy industry. In CFD simulations, a turbulence model plays a significantly important role in accuracy and resource cost. In this paper, a novel ... -
On the unreasonable reliability of mathematical inference
(2022-08-03)In (Avigad, 2020), Jeremy Avigad makes a novel and insightful argument, which he presents as part of a defence of the ‘Standard View’ about the relationship between informal mathematical proofs (that is, the proofs that ... -
On the use of decoupled and adapted Gaussian mixture models for open-set speaker identification
(Office for Official Publications of the European Communities, 2005)This paper presents a comparative analysis of the performance of decoupled and adapted Gaussian mixture models (GMMs) for open-set, text-independent speaker identification (OSTISI). The analysis is based on a set of ... -
On the use of discrete adjoints in goal error estimation for shallow water equations
(2010)Goal oriented dual weight error estimation has been used in context of computational fluid dynamics for several years. The adaptation of this method to geophysical models is the subject of this paper. A differentiation-enabled ... -
On the use of vibration parameters for the estimation of damage in laminated composite plates
(2010-01-01)The dynamic response of a structure depends on the system's particular characteristics, namely its mass, stiffness and damping properties. Vibration-based damage detection techniques assume that damage will induce a local ... -
On the α /Fe Bimodality of the M31 Disks
(2023-10-10)An outstanding question is whether the α/Fe bimodality exists in disk galaxies other than in the Milky Way. Here we present a bimodality using our state-of-the-art galactic chemical evolution models that can explain various ... -
On undecidability results of real programming languages
(2009)Often, it is argued that some problems in data-flow analysis such as e.g. worst case execution time analysis are undecidable (because the halting problem is) and therefore only a conservative approximation of the desired ... -
On Virtuality and the aesthetics of spectacle: Nationalist Imaginations of Mthwakazi and its passions of semblance : Nationalist Imaginations of Mthwakazi and its passions of semblance
(2017-08-14)Abstract Social networking and the individuated privacy of the virtual space have emerged as new forms of conflating social identities and free speech for most subaltern communities. While it is clearly accepted that the ... -
On what we may infer from artistic and scientific representations of time
(2012)We consider the extent to which artistic and scientific representations can give us knowledge of how things are or could be. Focusing on representations of time, we take two case studies: simultaneity and temporal order; ...
