Effects of deacetylation degree of chitosan on the structure of aerogels
International Journal of Biological Macromolecules, 2023 Chitosan aerogels, obtained by (supercritical) CO2 drying of hydrogels, are novel adsorbents because of their large surface area and high porosity. Intrinsic properties of chitosan such as molecular weight (MW) and degree of deacetylation (DDA) had large impacts on the characteristics of chitosan aerogels.

On Shrinkage Estimators and “Effective Degrees of Freedom”
, 2020 Explicit expressions for the estimated mean \(\tilde {\mathbf {y}}_k = X\tilde {\boldsymbol {\beta }}_k = H_k\mathbf {y}\) and effective degrees of freedomνk = tr(Hk) by penalized least squares, with penalty k||Dβ||2, can be found readily when X′X + D′D is nonsingular.

Effect of degree distribution on evolutionary search
Proceedings of the 11th Annual conference on Genetic and evolutionary computation, 2009 This paper introduces a method to generate hierarchically modular networks with prescribed node degree list and proposes a metric to measure network modularity based on the notion of edge distance. The generated networks are used as test problems to explore the effect of modularity and degree distribution on evolutionary algorithm performance.
