Can the Clobber game become a classroom-based tool for screening students' executive functions?

The use of games for cognitive screening is not new and involves employing simple tasks as well as virtual reality. In this work, we introduce the use of the combinatorial game Clobber, created by the mathematicians Albert, Grossman, Nowakowski and Wolfe in 2001 in a classroom-based experiment and analyzed how it can assess cognitive functions. Specifically, this study tries to address how the use of the Clobber game can target executive functions (EFs) and why it may be a valuable game to assess EFs.

Identifying simultaneous rearrangements in cancer genomes.

Motivation: The traditional view of cancer evolution states that a cancer genome accumulates a sequential ordering of mutations over a long period of time. However, in recent years it has been suggested that a cancer genome may instead undergo a one-time catastrophic event, such as chromothripsis, where a large number of mutations instead occur simultaneously. A number of potential signatures of chromothripsis have been proposed.

New Genome Similarity Measures based on Conserved Gene Adjacencies.

Many important questions in molecular biology, evolution, and biomedicine can be addressed by comparative genomic approaches. One of the basic tasks when comparing genomes is the definition of measures of similarity (or dissimilarity) between two genomes, for example, to elucidate the phylogenetic relationships between species. The power of different genome comparison methods varies with the underlying formal model of a genome.

Genomic Distance with High Indel Costs.

We determine complexity of computing the DCJ-indel distance, when DCJ and indel operations have distinct constant costs, by showing an exact formula that can be computed in linear time for any choice of (constant) costs for DCJ and indel operations. We additionally consider the problem of triangular inequality disruption and propose an algorithmically efficient correction on each member of the family of DCJ-indel.

DCJ-indel and DCJ-substitution distances with distinct operation costs.

Background: Classical approaches to compute the genomic distance are usually limited to genomes with the same content and take into consideration only rearrangements that change the organization of the genome (i.e. positions and orientation of pieces of DNA, number and type of chromosomes, etc.

Restricted DCJ-indel model: sorting linear genomes with DCJ and indels.

Background: The double-cut-and-join (DCJ) is a model that is able to efficiently sort a genome into another, generalizing the typical mutations (inversions, fusions, fissions, translocations) to which genomes are subject, but allowing the existence of circular chromosomes at the intermediate steps. In the general model many circular chromosomes can coexist in some intermediate step. However, when the compared genomes are linear, it is more plausible to use the so-called restricted DCJ model, in which we proceed the reincorporation of a circular chromosome immediately after its creation.

Metabolism of a lipid nanoemulsion resembling low-density lipoprotein in patients with grade iii obesity.

Introduction: Obesity increases triglyceride levels and decreases high-density lipoprotein concentrations in plasma. Artificial emulsions resembling lipidic plasma lipoprotein structures have been used to evaluate low-density lipoprotein metabolism. In grade III obesity, low density lipoprotein metabolism is poorly understood.
