ACT-R Based Models For Learning Interactive Layouts
… of interactive layouts. I develop two models based on a theory of cognition known as ACT-R (Adaptive Control of Thought–Rational). I validate them against experimental data collected by other researchers. The first model is a simulation model that emulates the transition from novice to expert …

Virologic outcomes of HIV-infected children undergoing a single-class drug substitution from Lopinavir/Ritonavir- to Efavirenz-based antiretroviral treatment: A retrospective cohort study
… (WHO) recommends lopinavir/ritonavir-based (LPV/r) cART as first-line for children <36 months old with the option to substitute LPV/r with a non-nucleoside reverse transcriptase inhibitor if virologic suppression is maintained. This simplification strategy is potentially cost-saving, …

Experimental determination of the yield locus of anisotropic metal sheets using digital image correlation
… from the stress-strain response. Hill's 1948 R-based and stress-based yield criteria, Hill's 1979 planar-isotropic yield criterion and Barlat's Yld2000-2d yield function were evaluated at each value of plastic work per unit volume, and compared against the experimental yield data obtained. A low …

MULTI-OMICS PROFILING DECODES BACE2-DEPENDENT METABOLIC REWIRING IN METASTATIC MELANOMA
… metabolomics, and LiP-MS within an integrative R-based analytical framework, we characterized metabolic alterations dependent on BACE2 activity. Our results reveal that BACE2 functions as a regulator of lipid uptake by modulating the shedding of key lipid transporters, thereby preventing excessive …

RNA sequencing for the study of gene expression regulation
… In the first part of my thesis I developed an R based pipeline for pre-processing, expression estimation and data quality assessment of RNA-seq datasets, which formed the basis for my subsequent work on the evolution of gene expression regulation in mammals. Since changes in gene expression …

Comparing vector-based and ACT-R memory models using large-scale datasets: User-customized hashtag and tag prediction on Twitter and StackOverflow
… they predict a user’s chosen tags: an ACT-R based Bayesian model and a random permutation vector-based model. Millions of posts and tweets were collected, and both declarative memory models were used to predict Twitter hashtags and StackOverflow tags. The results show that past user behavior …

On complex reflection groups G(m, 1, r) and their Hecke algebras
… finite Coxeter groups to the groups G(m, 1, r). Based on this, we prove that a character value of any element in an Ariki-Koike algebra (the Hecke algebra of a G(m, 1, r)) can be determined by the character values of some special elements in the algebra. These special elements correspond to the …

Multiscale coarse-grained models for biological phase separation: Development and applications
… the rest of the interactions, while keeping R–based interactions stronger than K–based ones. The parameterisation is based on atomistic PMF calculations and bioinformatics data on π-based contacts. The Mpipi Recharged model is a finer and more optimised version of Mpipi, that appropriately …

Hybrid methodology for Markovian epidemic models
… it is often the case that estimates of R₀ based on data from the initial stages of an outbreak are positively biased. This bias may be the result of various features such as the geography and demography of the outbreak. However, a consideration which is often overlooked is that the outbreak …
