Using genetic algorithms with grammar encoding to generate neural networks [PDF]

open access: yes, 1995
Kitano's approach to neural network design is extended in the sense that not just the neural network structure, but also the values of the weights are coded in the chromosome.

Induction of crossover by introduction of aro554 Tn10 into Salmonella chromosome

open access: yesFrontiers in Bioscience, 2015
One of the ancient methods for the generation of bacterial mutants was to insert the composite transposable elements (e.g. Tn10) flanked by desired gene sequences, into the bacterial chromosome. This mechanism of DNA integrating into a chromosome can sometimes not only lead to the creation of desired mutants but also induced other recombination event ...

An Adaptive Elephant Herd Optimization‐based Load Balancing Algorithm for energy efficient Networks

open access: yesIET Networks, Accepted Article.
Distributing resources among PCs, networks, and servers enables organizations to better manage their workloads and applications. The AEHO algorithm was used in this study to design a load‐balancing system. The elephant population is alienated into clans, with each point on the elephant's trunk denoting a different type of solution.

Role of the Srs2-Rad51 Interaction Domain in Crossover Control in Saccharomyces cerevisiae. [PDF]

open access: yes, 2019
Saccharomyces cerevisiae Srs2, in addition to its well-documented antirecombination activity, has been proposed to play a role in promoting synthesis-dependent strand annealing (SDSA).

Matefin/SUN-1 phosphorylation is part of a surveillance mechanism to coordinate chromosome synapsis and recombination with meiotic progression and chromosome movement.

open access: yesPLoS Genetics, 2013
Faithful chromosome segregation during meiosis I depends on the establishment of a crossover between homologous chromosomes. This requires induction of DNA double-strand breaks (DSBs), alignment of homologs, homolog association by synapsis, and repair of

Advent of NK3R Antagonists for the Treatment of Menopausal Hot Flushes: A Narrative Review

open access: yesBJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT The menopause transition is marked by symptoms predominantly attributed to declining oestrogen levels. Approximately 80% of women experience associated symptoms, and 25% experience severe symptoms. The commonest are vasomotor symptoms (VMS), collectively referring to hot flushes and/or night sweats.

Synapsis and recombination of autosomes and sex chromosomes in two terns (Sternidae, Charadriiformes, Aves)

open access: yesВавиловский журнал генетики и селекции, 2017
The frequency of recombination and the patterns of crossover site distribution along the chromosomes vary considerably among animal species, including closely related species.

SOX30 Governs Synaptonemal Complex Assembly and Homologous Recombination in Male Meiosis

open access: yesCell Proliferation, EarlyView.
The transcription factor SOX30 directly binds promoter regions of SYCE1 and SYCE2 to mediate their transcriptional activation, thereby enabling proper assembly of central elements within the synaptonemal complex. Structural destabilisation of the synaptonemal complex in Sox30 KK spermatocytes triggers synaptic discontinuity, impairs homologous ...

Achiasmy: Male fruit flies are not ready to mix

open access: yesFrontiers in Cell and Developmental Biology, 2016
Maintenance of the chromosomal copy number over generations and recombination between homologous chromosomes is a hallmark of meiotic cell division.
