Mechanical Mechanisms of Chromosome Segregation [PDF]

open access: yesCells, 2021
Chromosome segregation—the partitioning of genetic material into two daughter cells—is one of the most crucial processes in cell division. In all Eukaryotes, chromosome segregation is driven by the spindle, a microtubule-based, self-organizing subcellular structure.

Imprinting Mechanisms [PDF]

open access: yesGenome Research, 1998
A number of recent studies have provided new insights into mechanisms that regulate genomic imprinting in the mammalian genome. Regions of allele-specific differential methylation (DMRs) are present in all imprinted genes examined. Differential methylation is erased in germ cells at an early stage of their development, and germ-line-specific ...

Application of sparry grain limestone petrographic analysis combining image processing and deep learning

open access: yesShiyou shiyan dizhi, 2023
Traditional carbonate rock slice identification is based on manual observation and description, which is highly subjective, mainly qualitative and difficult to quantify.

Review on molecular structures of asphaltene macromolecules and instrumental analytical approaches

open access: yesShiyou shiyan dizhi, 2023
As one of the major fractions of petroleum and/or source rock extracts, asphaltene is commonly characte-rized by complicate molecular structures as well as relatively higher molecular weight (MW).

Reallocation Mechanisms [PDF]

open access: yes, 2014
We consider reallocation problems in settings where the initial endowment of each agent consists of a subset of the resources. The private information of the players is their value for every possible subset of the resources.

Ribosome Mechanics Informs about Mechanism [PDF]

open access: yesJournal of Molecular Biology, 2016
The essential aspects of the ribosome's mechanism can be extracted from coarse-grained simulations, including the ratchet motion, the movement together of critical bases at the decoding center, and movements of the peptide tunnel lining that assist in the expulsion of the synthesized peptide. Because of its large size, coarse graining helps to simplify

Interplay between ADP-ribosyltransferases and essential cell signaling pathways controls cellular responses

open access: yesCell Discovery, 2021
Signaling cascades provide integrative and interactive frameworks that allow the cell to respond to signals from its environment and/or from within the cell itself.

Modelling and simulation of a waste sorting mechatronic system for multi-floor residential buildings [PDF]

open access: yesE3S Web of Conferences, 2019
The paper presents modelling and simulation of a mechatronic sorting system for residential buildings where the “wet” garbage can be used as fuel in an energy generation system.

Virophages and retrotransposons colonize the genomes of a heterotrophic flagellate

open access: yeseLife, 2021
Virophages can parasitize giant DNA viruses and may provide adaptive anti-giant virus defense in unicellular eukaryotes. Under laboratory conditions, the virophage mavirus integrates into the nuclear genome of the marine flagellate Cafeteria burkhardae ...

Exotic mitotic mechanisms [PDF]

open access: yes, 2012
The emergence of eukaryotes around two billion years ago provided new challenges for the chromosome segregation machineries: the physical separation of multiple large and linear chromosomes from the microtubule-organizing centres by the nuclear envelope.
