Bayesian and non-bayesian evidential updating

open access: yesArtificial Intelligence, 1987
Orthodox probability theory supposes that (1) we commence with known statistical distributions, (2) these distributions give rise to real- valued probabilities, and (3) these probabilities can be updated by the use of Bayes' theorem. Each of these suppositions has been challenged by recent work in computer science concerning the representation and ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

An explanatory differential item functioning (DIF) model by the WinBUG 1.4 [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2007
This study proposed a multilevel logistic regression model to evaluate a source of DIF. The model accounts for the three levels nested structure of the data and combines results of logistic regression analysesto identify level-3 unit characteristic ...

Single‐cell DNA methylation profiling: Technologies, computation, and applications in precision oncology

open access: yesMolecular Oncology, EarlyView.
Single‐cell DNA methylation (scDNAme) profiling maps epimutational clonal evolution, revealing mechanisms of malignancy and therapeutic resistance across diverse cancer types. By providing a high‐resolution landscape of intratumoral heterogeneity, these technologies empower precise patient stratification, guide the development of enhanced ...

Probabilistic optimization in the human perceptuo-motor system

open access: yesJournal of Physical Fitness and Sports Medicine, 2013
Despite the variability of internal and external environments, the human central nervous system (CNS) can generate precise and stable perception and motor behaviors. What mechanism enables this ability?

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

open access: yesMolecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Modeling forest bird population trends at U.S. Army Garrison Pōhakuloa Training Area, Hawaiʻi

open access: yesAvian Conservation and Ecology
Hawaiian avifaunal communities have suffered irrevocable harm and significant threats remain for extant species. It is increasingly important to monitor and document bird density to improve our understanding of how remaining species respond to changing ...

Transcranial Direct Current Stimulation (tDCS) over the Intraparietal Sulcus Does Not Influence Working Memory Performance

open access: yesPsychologica Belgica, 2021
Mixed results of the impact of transcranial direct current stimulation (tDCS) on working memory have been reported. Contrarily to previous studies who focused mainly on stimulating the dorsolateral prefrontal cortex, we modulated the left intraparietal ...
