Bayesian evolutionary model testing in the phylogenomics era: matching model complexity with computational efficiency KU Leuven
The advent of new sequencing technologies has led to increasing amounts of data being available to perform phylogenetic analyses, with genomic data giving rise to the field of phylogenomics. High-performance computing is becoming an indispensable research tool to fit complex evolutionary models, which take into account specific genomic properties, to large datasets. Here, we perform an extensive Bayesian phylogenetic model selection study, ...
Cylinders or walls? A new computational model to estimate the MR transverse relaxation rate dependence on trabecular bone architecture. Vrije Universiteit Brussel
OBJECTIVE:
Bone density is distributed in a complex network of interconnecting trabecular plates and rods that are interspersed with bone marrow. A computational model to assess the dependence of the relaxation rate on the geometry of bone can consider the distribution of bone material in the form of two components: cylinders and open walls (walls with gaps). We investigate whether the experimentally known dependence of the ...

How creative should creators be to optimize the evolution of ideas? A computational model Vrije Universiteit Brussel
There are both benefits and drawbacks to creativity. In a social group it is not necessary for all
members to be creative to benefit from creativity; some merely imitate or enjoy the fruits of others'
creative efforts. What proportion should be creative? This paper outlines investigations of this question
carried out using a computer model of cultural evolution referred to as EVOC (for EVOlution
of Culture). EVOC is ...

Computational fluid dynamics model to predict the dynamical behavior of the cerebrospinal fluid through implementation of physiological boundary conditions Universiteit Gent
Improved alpha-beta power reduction via combined electrical and ultrasonic stimulation in a parkinsonian cortex-basal ganglia-thalamus computational model Universiteit Gent
Objective. To investigate computationally the interaction of combined electrical and ultrasonic modulation of isolated neurons and of the parkinsonian cortex-basal ganglia-thalamus loop. Approach. Continuous-wave or pulsed electrical and ultrasonic neuromodulation is applied to isolated Otsuka plateau-potential generating subthalamic nucleus (STN) and Pospischil regular, fast and low-threshold spiking cortical cells in a temporally alternating ...
New regression model with four regression structures and computational aspects Universiteit Hasselt Universiteit Antwerpen
A new general class of exponentiated sinh Cauchy regression models for location, scale, and shape parameters is introduced and studied. It may be applied to censored data and used more effectively in survival analysis when compared with the usual models. For censored data, we employ a frequentist analysis for the parameters of the proposed model. Further, for different parameter settings, sample sizes, and censoring percentages, various ...
