  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: 'A corner cut in dimension d is a finite subset of N0d that can be separated
    from its complement in N0d by an affine hyperplane disjoint from N0d. Corner cuts
    were first investigated by Onn and Sturmfels [Adv. Appl. Math. 23 (1999) 29-48],
    their original motivation stemmed from computational commutative algebra. Let
    us write (Nd0k)cut for the set of corner cuts of cardinality k; in the computational
    geometer''s terminology, these are the k-sets of N0d. Among other things, Onn
    and Sturmfels give an upper bound of O(k2d(d-1)/(d+1)) for the size of (Nd0k)cut
    when the dimension is fixed. In two dimensions, it is known (see [Corteel et al.,
    Adv. Appl. Math. 23 (1) (1999) 49-53]) that #(Nd0k)cut = Θ(k log k). We will see
    that in general, for any fixed dimension d, the order of magnitude of #(Nd0k)cut
    is between kd-1 log k and (k log k)d-1. (It has been communicated to me that the
    same bounds have been found independently by G. Rémond.) In fact, the elements
    of (Nd0k)cut correspond to the vertices of a certain polytope, and what our proof
    shows is that the above upper bound holds for the total number of flags of that
    polytope.'

  text: Intersection graphs of disks and of line segments, respectively, have been
    well studied, because of both, practical applications and theoretically interesting
    properties of these graphs. Despite partial results, the complexity status of
    the Clique problem for these two graph classes is still open. Here, we consider
    the Clique problem for intersection graphs of ellipses which in a sense, interpolate
    between disc and ellipses, and show that it is APX-hard in that case. Moreover,
    this holds even if for all ellipses, the ratio of the larger over the smaller
    radius is some prescribed number. To our knowledge, this is the first hardness
    result for the Clique problem in intersection graphs of objects with finite description
    complexity. We also describe a simple approximation algorithm for the case of
    ellipses for which the ratio of radii is bounded.

  text: In this investigation, we report identification and characterization of a
    95 kDa postsynaptic density protein (PSD-95)/discs-large/ ZO-1 (PDZ) domain-containing
    protein termed tamalin, also recently named GRP1-associated scaffold protein (GRASP),
    that interacts with group 1 metabotropic glutamate receptors (mGluRs). The yeast
    two-hybrid system and in vitro pull-down assays indicated that the PDZ domain-containing,
    amino-terminal half of tamalin directly binds to the class I PDZ-binding motif
    of group 1 mGluRs. The C-terminal half of tamalin also bound to cytohesins, the
    members of guanine nucleotide exchange factors (GEFs) specific for the ADP-ribosylation
    factor (ARF) family of small GTP-binding proteins. Tamalin mRNA is expressed predominantly
    in the telencephalic region and highly overlaps with the expression of group 1
    mGluR mRNAs. Both tamalin and cytohesin-2 were enriched and codistributed with
    mGluR1a in postsynaptic membrane fractions. Importantly, recombinant and native
    mGluR1a/tamalin/cytohesin-2 complexes were coimmunoprecipitated from transfected
    COS-7 cells and rat brain tissue, respectively. Transfection of tamalin and mutant
    tamalin lacking a cytohesin-binding domain caused an increase and decrease in
    cell-surface expression of mGluR1a in COS-7 cells, respectively. Furthermore,
    adenovirus-mediated expression of tamalin and dominant-negative tamalin facilitated
    and reduced the neuritic distribution of endogenous mGluR5 in cultured hippocampal
    neurons, respectively. The results indicate that tamalin plays a key role in the
    association of group 1 mGluRs with the ARF-specific GEF proteins and contributes
    to intracellular trafficking and the macromolecular organization of group 1 mGluRs
    at synapses.

  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: A new solvent-free composite polymer electrolyte consisting of high-molecular
    mass polyethylene oxide (PEO) filled with titanium oxide and containing LiI and
    I2 was developed. The introduction of the inorganic filler (TiO2 Degussa P25)
    into the polymer matrix produces dramatic morphological changes to the host polymer
    structure. Upon addition of the inorganic oxide, the surface roughness increases,
    with respect to the original polymer and in parallel, the fractal dimension decreases.
    Both the thermograms and the atomic force microscope (AFM) pictures confirm the
    amorphicity of the composite electrolyte. The polymer sub-units are held together
    in a parallel orientation, forming straight long chains of about 500 nm in width,
    along which TiO2 spherical particles of about 20-25 nm in diameter are distributed.
    The polymer chains separated by the titania particles are arranged in a three-dimensional,
    mechanically stable network, that creates free space and voids into which the
    iodide/triodide anions can easily migrate. All solid-state dye-sensitized solar
    cells fabricated using this composite electrolyte present high efficiencies (typical
    maximum incident photon to current efficiency (IPCE) as high as 40% at 520 nm
    and overall conversion efficiency (η) of 0.96% (Voc = 0.67 V, Jsc = 2.050 mA/cm2,
    FF = 39%) under direct solar irradiation. Further improvement of the photovoltaic
    performance is expected by optimization of the electrolyte parameters and of the
    cell assembly.

  text: New dyes of the type Ru(II)(bdmpp)(bpy) [where bdmpp is 2,6-bis(3,5-dimethyl-N-pyrazoyl)pyridine
    and bpy is 2,2′-bipyridine-4,4′-dicarboxylic acid] are prepared and characterized
    by infra-red (IR), mass (MS) and electrospray mass spectroscopy (ES-MS) as well
    as 1H NMR (1D and 2D) spectroscopies. The compounds present broad and very high
    intensity MLCT absorption bands in the visible and can be chemically anchored
    on TiO2 films via ester-like linkage involving carboxylato groups. These complexes
    have been tested with success as potential molecular antennas in dye-sensitized
    solar cells. Both opaque and transparent nanocrystalline TiO2 thin film electrodes
    obtained by a doctor blade technique sensitized by these complexes were incorporated
    in a sandwich type regenerative photoelectrochemical solar cell containing 0.1M
    LiI +0.01M I2 in propylene carbonate as well as a platinized conductive glass
    counter electrode. The cell was characterized by Raman spectroscopy under anodic
    and cathodic bias. Two new vibration bands were observed in the lower frequency
    region. The first one at 112 cm-1 is due to tri-iodide formed on the photoactive
    electrode, and the second one at 167 cm-1 is a sign of the dye/iodide interaction
    and corresponds to a vibration in a chemically stable &quot;DI&quot; intermediate
    species. Under direct sunlight illumination (solar irradiance of 60 mW/cm2) by
    using a composite polymer solid state electrolyte, the cell ITO/TiO2/[Ru(II)(bdmpp)(bpy)(NCS)](PF6)/electrolyte/Pt-ITO
    produced a continuous photocurrent as high as 4.29mA/cm2, and gave IPCE values
    about half of the corresponding values obtained by the standard N3 dye under the
    same conditions. The photovoltage is about 600 mV and the overall energy conversion
    cell's efficiency is as high as 1.72%.

  text: Poly(ethylene oxide)/titania polymer electrolyte based photoelectrochemical
    cells have been fabricated with Ru(dcbpy)2(NCS)2 complex as the sensitizer and
    nanoporous TiO2 films as photoanodes. The introduction of the titania filler into
    the poly(ethylene oxide) matrix reduces the crystallinity of the polymer and enhances
    the mobility of the 1-/13 - redox couple, resulting in outstanding overall conversion
    efficiency (4.2% under direct sunlight illumination) of the corresponding dye-sensitized
    nanocrystalline TiO2 solar cell, one of the best efficiencies reported to date
    for a solid-state device.

  text: "The recent discovery of bright quasars around redshift z=6 suggests that
    black holes (BHs) with masses in excess of 10^9 Msun have already assembled at
    a very early stage in the evolution of the universe. An alternative interpretation
    is that these quasars are powered by less massive BHs, but their fluxes are strongly
    magnified through gravitational lensing by intervening galaxies. Here we analyze
    the flux distribution of the Ly alpha emission of the quasar with the highest
    known redshift, SDSS 1030+0524, at z=6.28. We show that this object could not
    have been magnified by lensing by more than a factor of five. The constraint arises
    from the large observed size, 30 (comoving) Mpc, of the ionized region around
    this quasar, and relies crucially only on the assumption that the quasar is embedded
    in a largely neutral IGM. Based on the line/continuum ratio of SDSS 1030+0524,
    we argue further that this quasar also cannot be beamed by a significant factor.
    We conclude that the minimum mass for its resident BH is 4 x 10^8 Msun (for magnification
    by a factor of five); if the mass is this low, then the quasars had to switch
    on prior to redshift z=9.\r\nFrom the size of the ionized region, we are also
    able to place an absolute lower bound on the age of this quasar at t > 2 x 10^7
    years."

  text: An extensive sample of galaxy clusters will be available in the coming years,
    detected through their Sunyaev-Zeldovich effect (SZE). We use a semianalytic model
    to study the scientific yield of combining SZE data with X-ray and optical follow-up
    observations. If clusters at a given redshift z0 can be identified with virialized,
    spherical halos, they populate a well-defined "fundamental plane" (FP) in the
    parameter space of the three observables virial temperature (T), total Sunyaev-Zeldovich
    flux decrement (ΔSν), and angular size (θ). The location and orientation of the
    FP, as well as its redshift evolution, are sensitive to both the internal evolution
    of clusters and to the underlying cosmological parameters. We show that if clusters
    are not standard candles (e.g., because of feedback or energy injection), then
    this can be inferred from the FP. Likewise, we study the dependence of the FP
    on the cosmological parameters h, σ8, and Ω0, and quantify future constraints
    on these parameters. We also show that in the absence of any nongravitational
    effects, the scatter in the (ΔSν,T)-plane is significantly smaller than in either
    the (θ,T) or the (θ,ΔSν) planes. As a result, the ΔSν-T relation can be an exceptionally
    sensitive probe of both cluster physics and cosmological parameters. A comparison
    of the amount of scatter in these three scaling relations will test the origin
    (cosmological vs. stochastic) of the scatter.

  text: For a source of Lyα radiation embedded in a neutral intergalactic medium (IGM)
    prior to the reionization epoch, the Lyα emission line is strongly suppressed
    by the intervening IGM. The damping wing of the so-called Gunn-Peterson trough
    can extend to the red side of the emission line and erase a significant fraction
    of the total line flux. However, the transmitted fraction increases with the size
    of the local cosmological H II region surrounding the source, and therefore with
    the ionizing luminosity and age of the source. Motivated by the recent discovery
    of a Lyα-emitting galaxy at a redshift z = 6.56 (Hu et al.), possibly prior to
    the reionization of the IGM, we revisit the effects of a neutral IGM on the Lyα
    emission line. We show that for faint sources with little or even no ionizing
    continuum, a sufficiently broad (Δv ≳ 300 km s^-1) emission line can still remain
    observable. In particular, the line detected by Hu et al. is consistent with a
    source embedded in a neutral IGM. We provide characterizations of the asymmetry
    and total transmitted flux of the Lyα line as functions of the ionizing emissivity
    of its source. We argue that a statistical sample of Lyα emitters extending beyond
    the reionization redshift can be a useful probe of reionization.

  text: The first generation of stars is thought to have formed in low-mass halos
    with Tvir < 10^4 K where H2 cooling is paramount. However, the efficiency of H2
    formation and cooling in these halos may have been severely limited by feedback
    processes. In this paper we investigate the radiative cooling and collapse of
    halos with virial temperatures Tvir > 10^4 K, i.e., those that can cool in the
    absence of H2 via neutral atomic lines. The evolution of these halos differs from
    their less massive counterparts. Efficient atomic line radiation allows rapid
    cooling to ~8000 K; subsequently the gas can contract nearly isothermally at this
    temperature. In the absence of H2 molecules, the gas would likely settle into
    a locally stable disk, and only disks with unusually low spin would be unstable.
    However, we find that the initial atomic line cooling leaves a large, out-of-equilibrium
    residual free electron fraction. This allows the molecular fraction to build up
    to a universal value of x ≈ 10^-3, almost independently of initial density and
    temperature. We show that this is a nonequilibrium freeze-out value that can be
    understood in terms of timescale arguments. Unlike in less massive halos, H2 formation
    and cooling is largely impervious to feedback from external UV fields, due to
    the high initial densities achieved by atomic cooling. The newly formed molecules
    cool the gas further to ~100 K and allow the gas to fragment on scales of a few
    times 100 M☉. We investigate the importance of various feedback effects such as
    H2 photodissociation from internal UV fields and radiation pressure due to Lyα
    photon trapping, which are likely to regulate the efficiency of star formation.

  text: Recent discoveries by the Sloan Digital Sky Survey (SDSS) of four bright z
    ~ 6 quasars could constrain the mechanism by which the supermassive black holes
    powering these sources are assembled. Here we compute the probability that the
    fluxes of the quasars are strongly amplified by gravitational lensing and therefore
    the likelihood that the black hole masses are overestimated when they are inferred
    assuming Eddington luminosities. The poorly constrained shape of the intrinsic
    quasar luminosity function (LF) at redshift ~6 results in a large range of possible
    lensing probabilities. If the LF is either steep or extends to faint magnitudes,
    the probability for amplification by a factor μ ≳ 10 (and with only one image
    detectable by SDSS) can reach essentially 100%. We show that future observations,
    in particular, of either the current four quasars at the high angular resolution
    provided by the Hubble Space Telescope or an increased sample of ~20 z ~ 6 quasars
    at the current angular resolution, should either discover several gravitational
    lenses or else provide interesting new constraints on the shape of the z ~ 6 quasar
    LF.

  text: The Sloan Digital Sky Survey (SDSS) is an imaging and spectroscopic survey
    that will eventually cover approximately one-quarter of the celestial sphere and
    collect spectra of ≈106 galaxies, 100,000 quasars, 30,000 stars, and 30,000 serendipity
    targets. In 2001 June, the SDSS released to the general astronomical community
    its early data release, roughly 462 deg2 of imaging data including almost 14 million
    detected objects and 54,008 follow-up spectra. The imaging data were collected
    in drift-scan mode in five bandpasses (u, g, r, i, and z); our 95% completeness
    limits for stars are 22.0, 22.2, 22.2, 21.3, and 20.5, respectively. The photometric
    calibration is reproducible to 5%, 3%, 3%, 3%, and 5%, respectively. The spectra
    are flux- and wavelength-calibrated, with 4096 pixels from 3800 to 9200 Å at R
    ≈ 1800. We present the means by which these data are distributed to the astronomical
    community, descriptions of the hardware used to obtain the data, the software
    used for processing the data, the measured quantities for each observed object,
    and an overview of the properties of this data set.

  text: The Sloan Digital Sky Survey has confirmed the existence of populations of
    broad absorption line (BAL) quasars with various unusual properties. We present
    and discuss 23 such objects and consider the implications of their wide range
    of properties for models of BAL outflows and quasars in general. We have discovered
    one BAL quasar with a record number of absorption lines. Two other similarly complex
    objects with many narrow troughs show broad Mg II absorption extending longward
    of their systemic host galaxy redshifts. This can be explained as absorption of
    an extended continuum source by the rotation-dominated base of a disk wind. Five
    other objects have absorption that removes an unprecedented ∼90% of all flux shortward
    of Mg II. The absorption in one of them has varied across the ultraviolet with
    an amplitude and rate of change as great as ever seen. This same object may also
    show broad Hβ absorption. Numerous reddened BAL quasars have been found, including
    at least one reddened mini-BAL quasar with very strong Fe II emission. The five
    reddest objects have continuum reddenings of E(B-V) ≃ 0.5, and in two of them
    we find strong evidence that the reddening curve is even steeper than that of
    the SMC. We have found at least one object with absorption from Fe III but not
    Fe II. This may be due to a high column density of moderately high ionization
    gas, but the Fe III level populations must also be affected by some sort of resonance.
    Finally, we have found two luminous, probably reddened high-redshift objects that
    may be BAL quasars whose troughs partially cover different regions of the continuum
    source as a function of velocity.
