text: 'BACKGROUND: Detection of changes in a protein''s evolutionary rate may reveal
cases of change in that protein''s function. We developed and implemented a simple
relative rates test in an attempt to assess the rate constancy of protein evolution
and to detect cases of functional diversification between orthologous proteins.
The test was performed on clusters of orthologous protein sequences from complete
bacterial genomes (Chlamydia trachomatis, C. muridarum and Chlamydophila pneumoniae),
complete archaeal genomes (Pyrococcus horikoshii, P. abyssi and P. furiosus) and
partially sequenced mammalian genomes (human, mouse and rat). RESULTS: Amino-acid
sequence evolution rates are significantly correlated on different branches of
phylogenetic trees representing the great majority of analyzed orthologous protein
sets from all three domains of life. However, approximately 1% of the proteins
from each group of species deviates from this pattern and instead shows variation
that is consistent with an acceleration of the rate of amino-acid substitution,
which may be due to functional diversification. Most of the putative functionally
diversified proteins from all three species groups are predicted to function at
the periphery of the cells and mediate their interaction with the environment.
CONCLUSIONS: Relative rates of protein evolution are remarkably constant for the
three species groups analyzed here. Deviations from this rate constancy are probably
due to changes in selective constraints associated with diversification between
orthologs. Functional diversification between orthologs is thought to be a relatively
rare event. However, the resolution afforded by the test designed specifically
for genomic-scale datasets allowed us to identify numerous cases of possible functional
diversification between orthologous proteins.'

text: In this Letter we exhibit a one-parameter family of new Taub-NUT instantons
parameterized by a half-line. The endpoint of the half-line will be the reducible
Yang-Mills instanton corresponding to the Eguchi-Hanson-Gibbons L2 harmonic 2-form,
while at an inner point we recover the Pope-Yuille instanton constructed as a
projection of the Levi-Civitá connection onto the positive su(2)+ ⊂ so(4) subalgebra.
Our method imitates the Jackiw-Nohl-Rebbi construction originally designed for
flat R4. That is we find a one-parameter family of harmonic functions on the Taub-NUT
space with a point singularity, rescale the metric and project the obtained Levi-Civitá
connection onto the other negative su(2)- ⊂ so(4) part. Our solutions will possess
the full U(2) symmetry, and thus provide more solutions to the recently proposed
U(2) symmetric ansatz of Kim and Yoon.

text: We address the problem of finding Abelian instantons of finite energy on the
Euclidean Schwarzschild manifold. This amounts to construct self-dual L2 harmonic
2-forms on the space. Gibbons found a non-topological L2 harmonic form in the
Taub-NUT metric, leading to Abelian instantons with continuous energy. We imitate
his construction in the case of the Euclidean Schwarzschild manifold and find
a non-topological self-dual L2 harmonic 2-form on it. We show how this gives rise
to Abelian instantons and identify them with SU(2)-instantons of Pontryagin number
2n2 found by Charap and Duff in 1977. Using results of Dodziuk and Hitchin we
also calculate the full L2 harmonic space for the Euclidean Schwarzschild manifold.

text: 'Motivation: The context of the start codon (typically, AUG) and the features
of the 5′ Untranslated Regions (5′ UTRs) are important for understanding translation
regulation in eukaryotic mRNAs and for accurate prediction of the coding region
in genomic and cDNA sequences. The presence of AUG triplets in 5′ UTRs (upstream
AUGs) might effect the initiation rate and, in the context of gene prediction,
could reduce the accuracy of the identification of the authentic start. To reveal
potential connections between the presence of upstream AUGs and other features
of 5′ UTRs, such as their length and the start codon context, we undertook a systematic
analysis of the available eukaryotic 5′ UTR sequences. Results: We show that a
large fraction of 5′ UTRs in the available cDNA sequences, 15-53% depending on
the organism, contain upstream ATGs. A negative correlation was observed between
the information content of the translation start signal and the length of the
5′ UTR. Similarly, a negative correlation exists between the ''strength'' of the
start context and the number of upstream ATGs. Typically, cDNAs containing long
5′ UTRs with multiple upstream ATGs have a ''weak'' start context, and in contrast,
cDNAs containing short 5′ UTRs without ATGs have ''strong'' starts. These counter-intuitive
results may be interpreted in terms of upstream AUGs having an important role
in the regulation of translation efficiency by ensuring low basal translation
level via double negative control and creating the potential for additional regulatory
mechanisms. One of such mechanisms, supported by experimental studies of some
mRNAs, includes removal of the AUG-containing portion of the 5′ UTR by alternative
splicing.'

text: Sex is thought to facilitate accumulation of initially rare beneficial mutations
by allowing simultaneous allele replacements at many loci. However, this advantage
of sex depends on a restrictive assumption that the fitness of a genotype is determined
by fitness potential, a single intermediate variable to which all loci contribute
additively, so that new alleles can accumulate in any order. Individual-based
simulations of sexual and asexual populations reveal that under generic selection,
sex often retards adaptive evolution. When new alleles are beneficial only if
they accumulate in a prescribed order, a sexual population may evolve two or more
times slower than an asexual population because only asexual reproduction allows
some overlap of successive allele replacements. Many other fitness surfaces lead
to an even greater disadvantage of sex. Thus, either sex exists in spite of its
impact on the rate of adaptive allele replacements, or natural fitness surfaces
have rather specific properties, at least at the scale of intrapopulation genetic
variability.

text: Genes with new functions often evolve by gene duplication. Alternative splicing
is another means of evolutionary innovation in eukaryotes, which allows a single
gene to encode functionally diverse proteins. We investigate a connection between
these two evolutionary phenomena. For ∼10% of the described cases of substitution
alternative splicing, such that either one or another amino acid sequence is included
into the protein, evidence of origin by tandem exon duplication was found. This
is a conservative estimate because alternative exons are typically short and,
on many occasions, duplicates may have diverged beyond recognition. Dating exon
duplications through a combination of the available experimental data on alternative
splicing in orthologous genes from different species and computational analysis
indicates that most of the duplications antedate at least the radiation of mammalian
orders or even the radiation of vertebrate classes. At present, tandem exon duplication
is the only mechanism of evolution of substitution alternative splicing that can
be specifically demonstrated. Along with gene duplication, this could be a major
route for generating functional diversity during evolution of multicellular eukaryotes.

text: 'The study and comparison of mutation(al) spectra is an important problem
in molecular biology, because these spectra often reflect on important features
of mutations and their fixation. Such features include the interaction of DNA
with various mutagens, the function of repair/replication enzymes, and properties
of target proteins. It is known that mutability varies significantly along nucleotide
sequences, such that mutations often concentrate at certain positions, called
"hotspots," in a sequence. In this paper, we discuss in detail two approaches
for mutation spectra analysis: the comparison of mutation spectra with a HG-PUBL
program, (FTP: sunsite.unc.edu/pub/academic/ biology/dna-mutations/hyperg) and
hotspot prediction with the CLUSTERM program (www.itba.mi.cnr.it/webmutation;
ftp.bionet.nsc.ru/pub/biology/dbms/clusterm.zip). Several other approaches for
mutational spectra analysis, such as the analysis of a target protein structure,
hotspot context revealing, multiple spectra comparisons, as well as a number of
mutation databases are briefly described. Mutation spectra in the lacI gene of
E. coli and the human p53 gene are used for illustration of various difficulties
of such analysis.'

text: Hyperlink analysis algorithms significantly improve the relevance of the search
results on the Web, so much so that all major Web search engines claim to use
some type of hyperlink analysis. However, the search engines do not disclose details
about the type of hyperlink analysis they perform, mostly to avoid manipulation
of search results by Web-positioning companies. The article discusses how hyperlink
analysis can be applied to ranking algorithms, and surveys other ways Web search
engines can use this analysis.
