text: We studied the effect of multilocus balancing selection on neutral nucleotide
variability at linked sites by simulating a model where diallelic polymorphisms
are maintained at an arbitrary number of selected loci by means of symmetric overdominance.
Different combinations of alleles define different genetic backgrounds that subdivide
the population and strongly affect variability. Several multilocus fitness regimes
with different degrees of epistasis and gametic disequilibrium are allowed. Analytical
results based on a multilocus extension of the structured coalescent predict that
the expected linked neutral diversity increases exponentially with the number
of selected loci and can become extremely large. Our simulation results show that
although variability increases with the number of genetic backgrounds that are
maintained in the population, it is reduced by random fluctuations in the frequencies
of those backgrounds and does not reach high levels even in very large populations.
We also show that previous results on balancing selection in single-locus systems
do not extend to the multilocus scenario in a straightforward way. Different patterns
of linkage disequilibrium and of the frequency spectrum of neutral mutations are
expected under different degrees of epistasis. Interestingly, the power to detect
balancing selection using deviations from a neutral distribution of allele frequencies
seems to be diminished under the fitness regime that leads to the largest increase
of variability over the neutral case. This and other results are discussed in
the light of data from the Mhc.

text: 'We extend current multilocus models to describe the effects of migration,
recombination, selection, and nonrandom mating on sets of genes in diploids with
varied modes of inheritance, allowing us to consider the patterns of nuclear and
cytonuclear associations (disequilibria) under various models of migration. We
show the relationship between the multilocus notation recently presented by Kirkpatrick,
Johnson, and Barton (developed from previous work by Barton and Turelli) and the
cytonuclear parameterization of Asmussen, Arnold, and Avise and extend this notation
to describe associations between cytoplasmic elements and multiple nuclear genes.
Under models with sexual symmetry, both nuclear-nuclear and cytonuclear disequilibria
are equivalent. They differ, however, in cases involving some type of sexual asymmetry,
which is then reflected in the asymmetric inheritance of cytoplasmic markers.
An example given is the case of different migration rates in males and females;
simulations using 2, 3, 4, or 5 unlinked autosomal markers with a maternally inherited
cytoplasmic marker illustrate how nuclear-nuclear and cytonuclear associations
can be used to separately estimate female and male migration rates. The general
framework developed here allows us to investigate conditions where associations
between loci with different modes of inheritance are not equivalent and to use
this nonequivalence to test for deviations from simple models of admixture. '

text: 'We calculate the fixation probability of a beneficial allele that arises
as the result of a unique mutation in an asexual population that is subject to
recurrent deleterious mutation at rate U. Our analysis is an extension of previous
works, which make a biologically restrictive assumption that selection against
deleterious alleles is stronger than that on the beneficial allele of interest.
We show that when selection against deleterious alleles is weak, beneficial alleles
that confer a selective advantage that is small relative to U have greatly reduced
probabilities of fixation. We discuss the consequences of this effect for the
distribution of effects of alleles fixed during adaptation. We show that a selective
sweep will increase the fixation probabilities of other beneficial mutations arising
during some short interval afterward. We use the calculated fixation probabilities
to estimate the expected rate of fitness improvement in an asexual population
when beneficial alleles arise continually at some low rate proportional to U.
We estimate the rate of mutation that is optimal in the sense that it maximizes
this rate of fitness improvement. Again, this analysis relaxes the assumption
made previously that selection against deleterious alleles is stronger than on
beneficial alleles. '

text: 'The simulation preorder for labeled transition systems is defined locally,
and operationally, as a game that relates states with their immediate successor
states. Simulation enjoys many appealing properties. First, simulation has a denotational
characterization: system S simulates system I iff every computation tree embedded
in the unrolling of I can be embedded also in the unrolling of S. Second, simulation
has a logical characterization: S simulates I iff every universal branching-time
formula satisfied by S is satisfied also by I. It follows that simulation is a
suitable notion of implementation, and it is the coarsest abstraction of a system
that preserves universal branching-time properties. Third, based on its local
definition, simulation between finite-state systems can be checked in polynomial
time. Finally, simulation implies trace containment, which cannot be defined locally
and requires polynomial space for verification. Hence simulation is widely used
both in manual and in automatic verification. Liveness assumptions about transition
systems are typically modeled using fairness constraints. Existing notions of
simulation for fair transition systems, however, are not local, and as a result,
many appealing properties of the simulation preorder are lost. We propose a new
view of fair simulation by extending the local definition of simulation to account
for fairness: system View the MathML sourcefairly simulates system View the MathML
source iff in the simulation game, there is a strategy that matches with each
fair computation of View the MathML source a fair computation of View the MathML
source. Our definition enjoys a denotational characterization and has a logical
characterization: View the MathML source fairly simulates View the MathML source
iff every fair computation tree (whose infinite paths are fair) embedded in the
unrolling of View the MathML source can be embedded also in the unrolling of View
the MathML source or, equivalently, iff every Fair-∀AFMC formula satisfied by
View the MathML source is satisfied also by View the MathML source (∀AFMC is the
universal fragment of the alternation-free μ-calculus). The locality of the definition
leads us to a polynomial-time algorithm for checking fair simulation for finite-state
systems with weak and strong fairness constraints. Finally, fair simulation implies
fair trace containment and is therefore useful as an efficiently computable local
criterion for proving linear-time abstraction hierarchies of fair systems.'

text: Now that the low temperature properties of quantum-mechanical many-body systems
(bosons) at low density, ρ, can be examined experimentally it is appropriate to
revisit some of the formulas deduced by many authors 4-5 decades ago. For systems
with repulsive (i.e. positive) interaction potentials the experimental low temperature
state and the ground state are effectively synonymous -- and this fact is used
in all modeling. In such cases, the leading term in the energy/particle is 2πℏ2aρ/m
where a is the scattering length of the two-body potential. Owing to the delicate
and peculiar nature of bosonic correlations (such as the strange N7/5 law for
charged bosons), four decades of research failed to establish this plausible formula
rigorously. The only previous lower bound for the energy was found by Dyson in
1957, but it was 14 times too small. The correct asymptotic formula has recently
been obtained by us and this work will be presented. The reason behind the mathematical
difficulties will be emphasized. A different formula, postulated as late as 1971
by Schick, holds in two-dimensions and this, too, will be shown to be correct.
With the aid of the methodology developed to prove the lower bound for the homogeneous
gas, two other problems have been successfully addressed. One is the proof by
us that the Gross-Pitaevskii equation correctly describes the ground state in
the `traps' actually used in the experiments. For this system it is also possible
to prove complete Bose condensation, as we have shown. Another topic is a proof
that Foldy's 1961 theory of a high density Bose gas of charged particles correctly
describes its ground state energy.

text: The Bose-Einstein condensation (BEC) of the ground state of bosonic atoms
in a trap was discussed. The BEC was proved for bosons with two-body repulsive
interaction potentials in the dilute limit, starting from the basic Schrodinger
equation. The BEC was 100% into the state which minimized the Gross-Pitaevskii
energy functional. The analysis also included rigorous proof of BEC in a physically
realistic, continuum model.

text: Using the Pauli-Fierz model of non-relativistic quantum electrodynamics, we
calculate the binding energy of an electron in the field of a nucleus of charge
Z and in presence of the quantized radiation field. We consider the case of small
coupling constant α, but fixed Zα and ultraviolet cut-off Λ. We prove that after
renormalizing the mass the binding energy has, to leading order in α, a finite
limit as Λ goes to infinity; i.e., the cut-off can be removed. The expression
for the ground state energy shift thus obtained agrees with Bethe's formula for
small values of Zα, but shows a different behavior for bigger values.

text: We study the Gross-Pitaevskii functional for a rotating two-dimensional Bose
gas in a trap. We prove that there is a breaking of the rotational symmetry in
the ground state; more precisely, for any value of the angular velocity and for
large enough values of the interaction strength, the ground state of the functional
is not an eigenfunction of the angular momentum. This has interesting consequences
on the Bose gas with spin; in particular, the ground state energy depends non-trivially
on the number of spin components, and the different components do not have the
same wave function. For the special case of a harmonic trap potential, we give
explicit upper and lower bounds on the critical coupling constant for symmetry
breaking.

text: We present a generalization of the Fefferman-de la Llave decomposition of
the Coulomb potential to quite arbitrary radial functions V on ℝn going to zero
at infinity. This generalized decomposition can be used to extend previous results
on N-body quantum systems with Coulomb interaction to a more general class of
interactions. As an example of such an application, we derive the high density
asymptotics of the ground state energy of jellium with Yukawa interaction in the
thermodynamic limit, using a correlation estimate by Graf and Solovej.

text: A commonly used theoretical definition of superfluidity in the ground state
of a Bose gas is based on the response of the system to an imposed velocity field
or, equivalently, to twisted boundary conditions in a box. We are able to carry
out this program in the case of a dilute interacting Bose gas in a trap, and we
prove that a gas with repulsive interactions is 100% superfluid in the dilute
limit in which the Gross-Pitaevskii equation is exact. This is the first example
in an experimentally realistic continuum model in which superfluidity is rigorously
verified.

text: Metabotropic glutamate receptors (mGluRs) from group III reduce glutamate
release. Because these receptors reduce cAMP levels, we explored whether this
signaling pathway contributes to release inhibition caused by mGluRs with low
affinity for L-2-amino-4-phosphonobutyrate (L-AP4). In biochemical experiments
with the population of cerebrocortical nerve terminals we find that L-AP4 (1 mM)
inhibited the Ca2+dependent-evoked release of glutamate by 25%. This inhibitory
effect was largely prevented by the pertussis toxin but was insensitive to inhibitors
of protein kinase C bisindolylmaleimide and protein kinase A H-89. Furthermore,
this inhibition was associated with reduction in N-type Ca2+ channel activity
in the absence of any detectable change in cAMP levels. In the presence of forskolin,
however, L-AP4 decreased the levels of cAMP. The activation of this additional
signaling pathway was very efficient in counteracting the facilitation of glutamate
release induced either by forskolin or the β-adrenergic receptor agonist isoproterenol.
Imaging experiments to measure Ca2+ dynamics in single nerve terminals showed
that L-AP4 strongly reduced the Ca2+ response in 28% of the nerve terminals. Moreover,
immunochemical experiments showed that 25-35% of the nerve terminals that were
immunopositive to synaptophysin were also immunoreactive to the low affinity L-AP4-sensitive
mGluR7. Then, mGluR7 mediates the inhibition of glutamate release caused by 1
mM L-AP4, primarily by a strong inhibition of Ca2+ channels, although high cAMP
uncovers the receptor ability to decrease cAMP.

text: Synapses exhibit different short-term plasticity patterns and this behaviour
influences information processing in neuronal networks. We tested how the short-term
plasticity of excitatory postsynaptic currents (EPSCs) depends on the postsynaptic
cell type, identified by axonal arborizations and molecular markers in the hippocampal
CA1 area. Three distinct types of short-term synaptic behaviour (facilitating,
depressing and combined facilitating-depressing) were defined by fitting a dynamic
neurotransmission model to the data. Approximately 75 % of the oriens-lacunosum-moleculare
(O-LM) interneurones received facilitating EPSCs, but in three of 12 O-LM cells
EPSCs also showed significant depression. Over 90 % of the O-LM cells were immunopositive
for somatostatin and mGluR1α and all tested cells were decorated by strongly mGluR7a
positive axon terminals. Responses in eight of 12 basket cells were described
well with a model involving only depression, but the other cells displayed combined
facilitating-depressing EPSCs. No apparent difference was found between the plasticity
of EPSCs in cholecystokinin- or parvalbumin-containing basket cells. In oriens-bistratified
cells (O-Bi), two of nine cells showed facilitating EPSCs, another two depressing,
and the remaining five cells combined facilitating-depressing EPSCs. Seven of
10 cells tested for somatostatin were immunopositive, but mGluR1α was detectable
only in two of 11 tested cells. Furthermore, most O-Bi cells projected to the
CA3 area and the subiculum, as well as outside the hippocampal formation. Postsynaptic
responses to action potentials recorded in vivo from a CA1 place cell were modelled,
and revealed great differences between and within cell types. Our results demonstrate
that the short-term plasticity of EPSCs is cell type dependent, but with significant
heterogeneity within all three interneurone populations.

text: 'Developmental responses to the plant hormone auxin are thought to be mediated
by interacting pairs from two protein families: short-lived inhibitory IAA proteins
and ARF transcription factors binding to auxin-response elements. Monopteros mutants
lacking activating ARF5 and the auxin-insensitive mutant bodenlos fail to initiate
the root meristem during early embryogenesis. Here we show that the bodenlos phenotype
results from an amino-acid exchange in the conserved degradation domain of IAA12.
BODENLOS and MONOPTEROS interact in the yeast two-hybrid assay and the two genes
are coexpressed in early embryogenesis, suggesting that BODENLOS inhibits MONOPTEROS
action in root meristem initiation.'

text: The hydra mutants of Arabidopsis are characterized by a pleiotropic phenotype
that shows defective embryonic and seedling cell patterning, morphogenesis, and
root growth. We demonstrate that the HYDRA1 gene encodes a Δ8-Δ7 sterol isomerase,
whereas HYDRA2 encodes a sterol C14 reductase, previously identified as the FACKEL
gene product. Seedlings mutant for each gene are similarly defective in the concentrations
of the three major Arabidopsis sterols. Promoter::reporter gene analysis showed
misexpression of the auxin-regulated DR5 and ACS1 promoters and of the epidermal
cell file-specific GL2 promoter in the mutants. The mutants exhibit enhanced responses
to auxin. The phenotypes can be rescued partially by inhibition of auxin and ethylene
signaling but not by exogenous sterols or brassinosteroids. We propose a model
in which correct sterol profiles are required for regulated auxin and ethylene
signaling through effects on membrane function.

text: Ran GTPase plays important roles in nucleocytoplasmic transport in interphase
[1, 2] and in both spindle formation and nuclear envelope (NE) assembly during
mitosis [3, 4, 5]. The latter functions rely on the presence of high local concentrations
of GTP-bound Ran near mitotic chromatin [3, 4, 5]. RanGTP localization has been
proposed to result from the association of Ran's GDP/GTP exchange factor, RCC1,
with chromatin [6, 7, 8, 9], but Ran is shown here to bind directly to chromatin
in two modes, either dependent or independent of RCC1, and, where bound, to increase
the affinity of chromatin for NE membranes. We propose that the Ran binding capacity
of chromatin contributes to localized spindle and NE assembly.

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: '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 Note we present pairs of hyperkähler orbifolds which satisfy two
different versions of mirror symmetry. On the one hand, we show that their Hodge
numbers (or more precisely, stringy E-polynomials) are equal. On the other hand,
we show that they satisfy the prescription of Strominger, Yau, and Zaslow (which
in the present case goes back to Bershadsky, Johansen, Sadov and Vafa): that a
Calabi-Yau and its mirror should fiber over the same real manifold, with special
Lagrangian fibers which are tori dual to each other. Our examples arise as moduli
spaces of local systems on a curve with structure group SL(n); the mirror is the
corresponding space with structure group PGL(n). The special Lagrangian tori come
from an algebraically completely integrable Hamiltonian system: the Hitchin system.'

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.
