Evolution favors protein mutational robustness in sufficiently large populations

open access: yesBMC Biology, 2007
Background An important question is whether evolution favors properties such as mutational robustness or evolvability that do not directly benefit any individual, but can influence the course of future evolution.

Determinative developmental cell lineages are robust to cell deaths. [PDF]

open access: yesPLoS Genetics, 2014
All forms of life are confronted with environmental and genetic perturbations, making phenotypic robustness an important characteristic of life. Although development has long been viewed as a key component of phenotypic robustness, the underlying ...

Quantum computing of delocalization in small-world networks [PDF]

open access: yes, 2005
We study a quantum small-world network with disorder and show that the system exhibits a delocalization transition. A quantum algorithm is built up which simulates the evolution operator of the model in a polynomial number of gates for exponential number

Evolution of dominance in gene expression pattern associated with phenotypic robustness

open access: yesBMC Ecology and Evolution, 2021
Background Mendelian inheritance is a fundamental law of genetics. When we consider two genomes in a diploid cell, a heterozygote’s phenotype is dominated by a particular homozygote according to the law of dominance.

Degeneracy: a design principle for achieving robustness and evolvability

open access: yes, 2009
Robustness, the insensitivity of some of a biological system's functionalities to a set of distinct conditions, is intimately linked to fitness. Recent studies suggest that it may also play a vital role in enabling the evolution of species.

Upstream plasticity and downstream robustness in evolution of molecular networks

open access: yesBMC Evolutionary Biology, 2004
Background Gene duplication followed by the functional divergence of the resulting pair of paralogous proteins is a major force shaping molecular networks in living organisms.

Observation of a localized flat-band state in a photonic Lieb lattice [PDF]

open access: yes, 2015
We show experimentally how a non-diffracting state can be excited in a photonic Lieb lattice. This lattice supports three energy bands, including a perfectly flat middle band, which corresponds to an infinite effective mass with zero dispersion.

Direct evolution of genetic robustness in microRNA [PDF]

open access: yesProceedings of the National Academy of Sciences, 2006
Genetic robustness, the invariance of the phenotype in the face of genetic perturbations, can endow the organism with reduced susceptibility to mutations. A large body of work in recent years has focused on the origins, mechanisms, and consequences of robustness in a wide range of biological systems.

Neutral Evolution of Robustness in Drosophila microRNA Precursors [PDF]

open access: yesMolecular Biology and Evolution, 2011
Mutational robustness describes the extent to which a phenotype remains unchanged in the face of mutations. Theory predicts that the strength of direct selection for mutational robustness is at most the magnitude of the rate of deleterious mutation. As far as nucleic acid sequences are concerned, only long sequences in organisms with high deleterious ...

Implementing Health‐Related Quality of Life Assessment in Pediatric Oncology: A Feasibility Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background There is growing interest in embedding health‐related quality of life (HRQoL) assessment and patient‐reported outcome measures (PROMs) within clinical cancer care. This study evaluated the feasibility, acceptability, and usability of implementing an electronic PROM (ePROM) platform to measure HRQoL in children with cancer ...
