text: 'BACKGROUND: Gene duplications have a major role in the evolution of new biological
functions. Theoretical studies often assume that a duplication per se is selectively
neutral and that, following a duplication, one of the gene copies is freed from
purifying (stabilizing) selection, which creates the potential for evolution of
a new function. RESULTS: In search of systematic evidence of accelerated evolution
after duplication, we used data from 26 bacterial, six archaeal, and seven eukaryotic
genomes to compare the mode and strength of selection acting on recently duplicated
genes (paralogs) and on similarly diverged, unduplicated orthologous genes in
different species. We find that the ratio of nonsynonymous to synonymous substitutions
(Kn/Ks) in most paralogous pairs is <<1 and that paralogs typically evolve
at similar rates, without significant asymmetry, indicating that both paralogs
produced by a duplication are subject to purifying selection. This selection is,
however, substantially weaker than the purifying selection affecting unduplicated
orthologs that have diverged to the same extent as the analyzed paralogs. Most
of the recently duplicated genes appear to be involved in various forms of environmental
response; in particular, many of them encode membrane and secreted proteins. CONCLUSIONS:
The results of this analysis indicate that recently duplicated paralogs evolve
faster than orthologs with the same level of divergence and similar functions,
but apparently do not experience a phase of neutral evolution. We hypothesize
that gene duplications that persist in an evolving lineage are beneficial from
the time of their origin, due primarily to a protein dosage effect in response
to variable environmental conditions; duplications are likely to give rise to
new functions at a later phase of their evolution once a higher level of divergence
is reached.'

text: We study fitness landscape in the space of protein sequences by relating sets
of human pathogenic missense mutations in 32 proteins to amino acid substitutions
that occurred in the course of evolution of these proteins. On average, ≈10% of
deviations of a nonhuman protein from its human ortholog are compensated pathogenic
deviations (CPDs), i.e., are caused by an amino acid substitution that, at this
site, would be pathogenic to humans. Normal functioning of a CPD-containing protein
must be caused by other, compensatory deviations of the nonhuman species from
humans. Together, a CPD and the corresponding compensatory deviation form a Dobzhansky-Muller
incompatibility that can be visualized as the corner on a fitness ridge. Thus,
proteins evolve along fitness ridges which contain only ≈10 steps between sucessive
corners. The fraction of CPDs among all deviations of a protein from its human
ortholog does not increase with the evolutionary distance between the proteins,
indicating that subtitutions that carry evolving proteins around these corners
occur in rapid succession, driven by positive selection. Data on fitness of interspecies
hybrids suggest that the compensatory change that makes a CPD fit usually occurs
within the same protein. Data on protein structures and on cooccurrence of amino
acids at different sites of multiple orthologous proteins often make it possible
to provisionally identify the substitution that compensates a partiCUlar CPD.

text: "Recent experimental breakthroughs in the treatment of dilute Bose gases have
renewed interest in their quantum mechanical description, respectively in approximations
to it. The ground state properties of dilute Bose gases confined in external potentials
and interacting via repulsive short range forces are usually described by means
of the Gross-Pitaevskii energy functional. In joint work with Elliott H. Lieb
and Jakob Yngvason its status as an approximation for the quantum mechanical many-body
ground state problem has recently been rigorously clarified. We present a summary
of this work, for both the two-and three-dimensional case.\r\n"

text: We study the ground state properties of an atom with nuclear charge Z and
N bosonic "electrons" in the presence of a homogeneous magnetic field
B. We investigate the mean field limit N→∞ with N / Z fixed, and identify three
different asymptotic regions, according to B≪Z2,B∼Z2,andB≫Z2 . In Region 1 standard
Hartree theory is applicable. Region 3 is described by a one-dimensional functional,
which is identical to the so-called Hyper-Strong functional introduced by Lieb,
Solovej and Yngvason for atoms with fermionic electrons in the region B≫Z3 ; i.e.,
for very strong magnetic fields the ground state properties of atoms are independent
of statistics. For Region 2 we introduce a general magnetic Hartree functional,
which is studied in detail. It is shown that in the special case of an atom it
can be restricted to the subspace of zero angular momentum parallel to the magnetic
field, which simplifies the theory considerably. The functional reproduces the
energy and the one-particle reduced density matrix for the full N-particle ground
state to leading order in N, and it implies the description of the other regions
as limiting cases.

text: We give upper bounds for the number of spin-1/2 particles that can be bound
to a nucleus of charge Z in the presence of a magnetic field B, including the
spin-field coupling. We use Lieb's strategy, which is known to yield Nc < 2Z
+ 1 for magnetic fields that go to zero at infinity, ignoring the spin-field interaction.
For particles with fermionic statistics in a homogeneous magnetic field our upper
bound has an additional term of the order of Z × min {(B/Z3)2/5, 1 + | 1n(B/Z3)|2}.

where ρ̅ is the average particle density and a the scattering length, the ground
state energy and density are rigorously shown to be given to leading order by
a Gross–Pitaevskii (GP) energy functional with a coupling constant g~1/|1n(ρ̅a
2)|. In contrast to the 3D case the coupling constant depends on N through the
mean density. The GP energy per particle depends only on Ng. In 2D this parameter
is typically so large that the gradient term in the GP energy functional is negligible
and the simpler description by a Thomas–Fermi type functional is adequate.

text: This paper concerns the asymptotic ground state properties of heavy atoms
in strong, homogeneous magnetic fields. In the limit when the nuclear charge Z
tends to ∞ with the magnetic field B satisfying B ≫ Z4/3 all the electrons are
confined to the lowest Landau band. We consider here an energy functional, whose
variable is a sequence of one-dimensional density matrices corresponding to different
angular momentum functions in the lowest Landau band. We study this functional
in detail and derive various interesting properties, which are compared with the
density matrix (DM) theory introduced by Lieb, Solovej and Yngvason. In contrast
to the DM theory the variable perpendicular to the field is replaced by the discrete
angular momentum quantum numbers. Hence we call the new functional a discrete
density matrix (DDM) functional. We relate this DDM theory to the lowest Landau
band quantum mechanics and show that it reproduces correctly the ground state
energy apart from errors due to the indirect part of the Coulomb interaction energy.

text: To study the role of mGlu7 receptors (mGluR7), we used homologous recombination
to generate mice lacking this metabotropic receptor subtype (mGluR7 -/-). After
the serendipitous discovery of a sensory stimulus-evoked epileptic phenotype,
we tested two convulsant drugs, pentylenetetrazole (PTZ) and bicuculline. In animals
aged 12 weeks and older, subthreshold doses of these drugs induced seizures in
mGluR7 -/-, but not in mGluR7 +/-, mice. PTZ-induced seizures were inhibited by
three standard anticonvulsant drugs, but not by the group III selective mGluR
agonist (R,S)-4-phosphonophenylglycine (PPG). Consistent with the lack of signs
of epileptic activity in the absence of specific stimuli, mGluR7 -/- mice showed
no major changes in synaptic properties in two slice preparations. However, slightly
increased excitability was evident in hippocampal slices. In addition, there was
slower recovery from frequency facilitation in cortical slices, suggesting a role
for mGluR7 as a frequency-dependent regulator in presynaptic terminals. Our findings
suggest that mGluR7 receptors have a unique role in regulating neuronal excitability
and that these receptors may be a novel target for the development of anticonvulsant
drugs.

text: In this paper we describe an intrinsically geometric way of producing magnetic
fields on S3 and R3 for which the corresponding Dirac operators have a non-trivial
kernel. In many cases we are able to compute the dimension of the kernel. In particular
we can give examples where the kernel has any given dimension. This generalizes
the examples of Loss and Yau [1].

text: We establish the exact low-energy asymptotics of the integrated density of
states (Lifschitz tail) in a homogeneous magnetic field and Poissonian impurities
with a repulsive single-site potential of Gaussian decay. It has been known that
the Gaussian potential tail discriminates between the so-called “classical” and
“quantum” regimes, and precise asymptotics are known in these cases. For the borderline
case, the coexistence of the classical and quantum regimes was conjectured. Here
we settle this last remaining open case to complete the full picture of the magnetic
Lifschitz tails.

text: We consider the time evolution of N bosonic particles interacting via a mean
field Coulomb potential. Suppose the initial state is a product wavefunction.
We show that at any finite time the correlation functions factorize in the limit
N → ∞. Furthermore, the limiting one particle density matrix satisfies the nonlinear
Hartree equation. The key ingredients are the uniqueness of the BBGKY hierarchy
for the correlation functions and a new apriori estimate for the many-body Schrödinger
equations.

text: Plants contain a novel unique subfamily of Rho GTPases, vital components of
cellular signalling networks. Here we report a general role for some members of
this family in polarized plant growth processes. We show that Arabidopsis AtRop4
and AtRop6 encode functional GTPases with similar intrinsic GTP hydrolysis rates.
We localized AtRop proteins in root meristem cells to the cross-wall and cell
plate membranes. Polar localization of AtRops in trichoblasts specifies the growth
sites for emerging root hairs. These sites were visible before budding and elongation
of the Arabidopsis root hair when AtRops accumulated at their tips. Expression
of constitutively active AtRop4 and AtRop6 mutant proteins in root hairs of transgenic
Arabidopsis plants abolished polarized growth and delocalized the tip-focused
Ca2+ gradient. Polar localization of AtRops was inhibited by brefeldin A, but
not by other drugs such as latrunculin B, cytochalasin D or caffeine. Our results
demonstrate a general function of AtRop GTPases in tip growth and in polar diffuse
growth.

text: Polar auxin transport is crucial for the regulation of auxin action and required
for some light-regulated responses during plant development. We have found that
two mutants of Arabidopsis - doc1, which displays altered expression of light-regulated
genes, and tir3, known for its reduced auxin transport - have similar defects
and define mutations in a single gene that we have renamed BIG. BIG is very similar
to the Drosophila gene Calossin/Pushover, a member of a gene family also present
in Caenorhabditis elegans and human genomes. The protein encoded by BIG is extraordinary
in size, 560 kD, and contains several putative Zn-finger domains. Expression-profiling
experiments indicate that altered expression of multiple light-regulated genes
in doc1 mutants can be suppressed by elevated levels of auxin caused by overexpression
of an auxin biosynthetic gene, suggesting that normal auxin distribution is required
to maintain low-level expression of these genes in the dark. Double mutants of
tir3 with the auxin mutants pin1, pid, and axr1 display severe defects in auxin-dependent
growth of the inflorescence. Chemical inhibitors of auxin transport change the
intracellular localization of the auxin efflux carrier PIN1 in doc1/tir3 mutants,
supporting the idea that BIG is required for normal auxin efflux.

text: Auxins represent an important class of plant hormone that regulate plant development.
Plants use specialized carrier proteins to transport the auxin indole-3-acetic
acid (IAA) to target tissues. To date, efflux carrier-mediated polar auxin transport
has been assumed to represent the sole mode of long distance IAA movement. Localization
of the auxin permease AUX1 in the Arabidopsis root apex has revealed a novel phloem-based
IAA transport pathway. AUX1, asymmetrically localized to the plasma membrane of
root protophloem cells, is proposed to promote the acropetal, post-phloem movement
of auxin to the root apex. MS analysis shows that IAA accumulation in aux1 mutant
root apices is impaired, consistent with an AUX1 phloem unloading function. AUX1
localization to columella and lateral root cap tissues of the Arabidopsis root
apex reveals that the auxin permease regulates a second IAA transport pathway.
Expression studies using an auxin-regulated reporter suggest that AUX1 is necessary
for root gravitropism by facilitating basipetal auxin transport to distal elongation
zone tissues.

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.

text: Empirical studies of the first generation of stars and quasars will likely
become feasible within the next decade in several different wavelength bands.
Microwave anisotropy experiments, such as MAP or Planck, will set constraints
on the ionization history of the intergalactic medium due to these sources. In
the infrared, the Next Generation Space Telescope (NGST) will be able to directly
detect sub-galactic objects at redshifts z>10. In the optical, data from the Hubble
Deep Field already places a constraint on the abundance of high-redshift quasars.
However, the epoch of the first quasars might be first probed in X-ray bands,
by instruments such as the Chandra X-ray Observatory (CXO) and the X-ray Multi-mirror
Mission (XMM). In a 500 Ksec integration, CXO reaches a sensitivity of 2x10-16
erg/s cm^2. Based on simple hierarchical CDM models, we find that at this flux
threshold approx. 100 quasars might be detectable from redshifts z>5, and approx.
1 quasar at z=10, in each 17x17 arcmin field. Measurement of the power spectrum
of the unresolved soft X-ray background will further constrain models of faint,
high-redshift quasars.

text: "Over the coming decade, the observational samples available for studies of
cluster abundance evolution will increase from tens to hundreds, or possibly to
thousands, of clusters. Here we assess the power of future surveys to determine
cosmological parameters. We quantify the statistical differences among cosmologies,
including the effects of the cosmic equation of state parameter w, in mock cluster
catalogs simulating a 12 deg^2 Sunyaev-Zel’dovich Effect (SZE) survey and a deep
10^4 deg^2 X-ray survey. The constraints from clusters are complementary to those
from studies of high-redshift Supernovae (SNe), CMB anisotropies, or counts of
high-redshift galaxies. Our results indicate that a statistical uncertainty of
a few percent on both Ωm\r\n and w can be reached when cluster surveys are used
in combination with any of these other datasets."
