Class decomposition for GA-based classifier agents – A Pitt approach [PDF]

open access: yes, 2004
Incremental learning has been widely addressed in the machine learning literature to cope with learning tasks where the learning environment is ever changing or training samples become available over time. However, most research work explores incremental

The Role of Mitotic Kinases and the RZZ Complex in Kinetochore-Microtubule Attachments: Doing the Right Link

open access: yesFrontiers in Cell and Developmental Biology, 2022
During mitosis, the interaction of kinetochores (KTs) with microtubules (MTs) drives chromosome congression to the spindle equator and supports the segregation of sister chromatids.

The genetic architecture of lipoprotein subclasses in Gullah-speaking African American families enriched for type 2 diabetes: The Sea Islands Genetic African American Registry (Project SuGAR)

open access: yesJournal of Lipid Research, 2010
We sought to partition the genetic and environmental influences on lipoprotein subclasses and identify genomic regions that may harbor genetic variants that influence serum lipoprotein levels in a sample of Gullah-speaking African-Americans. We genotyped

Inference of plasmid copy number mean and noise from single cell gene expression data

open access: yes, 2010
Plasmids are extra-chromosomal DNA molecules which code for their own replication. We previously reported a setup using genes coding for fluorescent proteins of two colors that allowed us, using a simple model, to extract the plasmid copy number noise in

In silico karyotyping of chromosomally polymorphic malaria mosquitoes in the Anopheles gambiae complex [PDF]

open access: yes, 2019
Chromosomal inversion polymorphisms play an important role in adaptation to environmental heterogeneities. For mosquito species in the Anopheles gambiae complex that are significant vectors of human malaria, paracentric inversion polymorphisms are ...

A nonparametric Bayesian approach to the rare type match problem

open access: yes, 2022
The "rare type match problem" is the situation in which the suspect's DNA profile, matching the DNA profile of the crime stain, is not in the database of reference.

The inner centromere is a biomolecular condensate scaffolded by the chromosomal passenger complex. [PDF]

open access: yes, 2019
The inner centromere is a region on every mitotic chromosome that enables specific biochemical reactions that underlie properties, such as the maintenance of cohesion, the regulation of kinetochores and the assembly of specialized chromatin, that can ...

Search for Risk Haplotype Segments with GWAS Data by Use of Finite Mixture Models [PDF]

open access: yes, 2015
The region-based association analysis has been proposed to capture the collective behavior of sets of variants by testing the association of each set instead of individual variants with the disease.

Chromosome partitioning in Escherichia coli: novel mutants producing anucleate cells [PDF]

open access: yesJournal of Bacteriology, 1989
To study the chromosomal partitioning mechanism in cell division, we have isolated a novel type of Escherichia coli mutants which formed anucleate cells, by using newly developed techniques. One of them, named mukA1, is not lethal and produces normal-sized anucleate cells at a frequency of 0.5 to 3% of total cells in exponentially growing populations ...

Coupling chromosome organization to genome segregation in Archaea

open access: yesNature Communications
Chromosome segregation is a fundamental process in all life forms and requires coordination with genome organization, replication and cell division. The mechanism that mediates chromosome segregation in archaea remains enigmatic.
