The problem of generalised minimum variance control of linear time-varying discrete-time systems is studied. Standard time-varying controlled autoregressive moving average models are considered, and the sum of plant output tracking error variance plus a penalty term on plant input is chosen as the cost functional. The timevarying controller described is able to minimise the generalised tracking...
This paper studies a new randomized quasi-Monte Carlo method for estimating the mean and variance of the Pareto distribution. In many Monte Carlo simulations, there are some stability problems for estimating the population Pareto variance by using the sample variance. In this paper, we propose a randomized quasi-random number generator [quasiRNG] to generate Pareto random samples, such that the...
In this paper, the effect of a change in the distribution of age differences between sexual partners on the dynamics of the HIV epidemic is studied. In a gender- and age-structured compartmental model, it is shown that if the variance of the distribution is small enough, an increase in this variance strongly increases the basic reproduction number. Moreover, if the variance is large enough, the...

Mechanism of photoprotection in the cyanobacterial ancestor of plant antenna proteins pp287 291 Hristina Staleva, Josef Komenda, Mahendra K Shukla, Václav Šlouf, Radek Kaňa, Tomáš Polívka & Roman Sobotka Light-harvesting complexes (LHCs) manage energy flux into photosynthesis and dissipate excess light energy. The demonstration of dissipative energy transfer from chlorophyll-a to β-carotene in ...
There are stable individual differences in exposure to stressful circumstances over time. The current study employed a latent trait-state model to estimate the magnitude of that stability and its sources. Adults (N = 327; age M = 43.9 years, SD = 6.15) provided reports of hassles and depressive symptoms every three months for two years. A Trait-State-Error model suggested that 60% of the varian...
The average copy number, the level of ampicillin resistance conferred by one plasmid, and the degree of plasmid multimerization were determined for several ColE1-like and pBR322-like plasmids. From the results obtained, the variance of the units of partition corresponding to each plasmid studied was calculated. Experimentally determined plasmid stability was compared with that calculated using ...
