Portfolios selected based on the sample covariance estimates may not be stable or robust, particularly so in situations with a large number of assets. The l1 or l2 norm constrained portfolio optimization method has been used as a robust method to control the sparsity or to shrink the estimated...

Biomass fast pyrolysis is a thermochemical conversion process to produce biofuels. However, the aqueous portion of pyrolysis liquid is usually considered a low-value product. This aqueous liquid can be used as an all-natural food flavoring referred to as liquid smoke in the food industry. This...

Liquid smoke as an all-natural food indigent is traditionally produced by smouldering. This process has a low efficiency and causes air pollution. Biomass pyrolysis is an advanced thermochemical process, which can replace smouldering and hence, transition the production towards a circular...

It is well established that phenotype and genotype misclassification errors reduce the power to detect genetic association. Resampling a subset of the data (e.g, double-sampling) of genotype and/or phenotype with a gold standard measurement is one method to address this issue. We derive the...

The transmission disequilibrium test (TDT) is a standard method to detect association using family trio design. It is optimal for an additive genetic model. Other TDT-type tests optimal for recessive and dominant models have also been developed. Association tests using family data, including the...
