Semi-Parametric Maximum Likelihood Method for Interaction in Case-Mother Control-Mother Designs: Package SPmlficmcm

open access: yesJournal of Statistical Software, 2015
The analysis of interaction effects involving genetic variants and environmental exposures on the risk of adverse obstetric and early-life outcomes is generally performed using standard logistic regression in the case-mother and control-mother design ...

Statistical analysis of maximum likelihood estimator images of human brain FDG PET studies [PDF]

open access: yes, 1993
The work presented evaluates the statistical characteristics of regional bias and expected error in reconstructions of real positron emission tomography (PET) data of human brain fluoro-deoxiglucose (FDG) studies carried out by the maximum likelihood ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Comparative analysis of the mitochondrial genome of Hypospila bolinoides and Lygephila dorsigera (Lepidoptera: Noctuoidea: Erebidae), with implications for their phylogeny

open access: yesEuropean Journal of Entomology, 2023
To analyse the phylogenetic relationships of members of the family Erebidae, the mitogenomes of two species namely, Hypospila bolinoides Guenée, 1852 and Lygephila dorsigera (Walker, 1865) were sequenced. H. bolinoides and L.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

A Maximum Likelihood Estimation Method for Underwater Radiated Noise Power

open access: yesApplied Sciences
Underwater radiated noise power estimation is crucial for the quantitative assessment of noise levels emitted by ships and underwater vehicles. This paper therefore proposes a maximum likelihood estimation method for determining the power of underwater ...

Implementation of the Multiple-Measure Maximum Likelihood strategy classification method in R [PDF]

open access: yesJudgment and Decision Making, 2010
One major challenge to behavioral decision research is to identify the cognitive processes underlying judgment and decision making. Gloeckner (2009) has argued that, compared to previous methods, process models can be more efficiently tested by ...

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.
