  text: A new experimental technique is described that uses reaction−diffusion phenomena
    as a means of one-step microfabrication of complex, multilevel surface reliefs.
    Thin films of dry gelatin doped with potassium hexacyanoferrate are chemically
    micropatterned with a solution of silver nitrate delivered from an agarose stamp.
    Precipitation reaction between the two salts causes the surface to deform. The
    mechanism of surface deformation is shown to involve a sequence of reactions,
    diffusion, and gel swelling/contraction. This mechanism is established experimentally
    and provides a basis of a theoretical lattice-gas model that allows prediction
    surface topographies emerging from arbitrary geometries of the stamped features.
    The usefulness of the technique is demonstrated by using it to rapidly prepare
    two types of mold for passive microfluidic mixers.

  text: Self-assembled monolayers (SAMs) of alkane thiols on gold and other metals
    are versatile constructs with which to study interfacial phenomena and reactions
    at surfaces. Surface properties of SAMs - e.g., wettability, stability in diverse
    environments, propensity to interact with or to resist adsorption of macromolecules
    -- depend on and can be controlled flexibly by the properties of the functional
    (head) groups in the w position of the alkyl chain. SAMs provide a basis for many
    important scientific and technological applications, ranging from micropatterning
    methods, through sensing, to biological recognition. Despite their importance,
    the literature on SAMs and the synthesis of molecules that constitute them remains
    scattered and often conflicting. The purpose of this Review is (i) to summarize
    the applications and physical properties of SAMs and (ii) to systematize the strategies
    of synthesis of ω-functionalized alkane thiols. Generic retrosynthetic scheme
    is developed that allows efficient synthetic planning. Issues related to the selection
    of appropriate protecting groups and the ways of introduction of the thiol functionality
    are discussed in detail, and illustrated with examples of syntheses of several
    complex alkane thiols.

  text: The paper surveys the mirror symmetry conjectures of Hausel-Thaddeus and Hausel-Rodriguez-Villegas
    concerning the equality of certain Hodge numbers of SL(n, ℂ) vs. PGL(n, ℂ) flat
    connections and character varieties for curves, respectively. Several new results
    and conjectures and their relations to works of Hitchin, Gothen, Garsia-Haiman
    and Earl-Kirwan are explained. These use the representation theory of finite groups
    of Lie-type via the arithmetic of character varieties and lead to an unexpected
    conjecture for a Hard Lefschetz theorem for their cohomology.

  text: Building on a recent paper [8], here we argue that the combinatorics of matroids
    are intimately related to the geometry and topology of toric hyperkähler varieties.
    We show that just like toric varieties occupy a central role in Stanley’s proof
    for the necessity of McMullen’s conjecture (or g-inequalities) about the classification
    of face vectors of simplicial polytopes, the topology of toric hyperkähler varieties
    leads to new restrictions on face vectors of matroid complexes. Namely in this
    paper we will give two proofs that the injectivity part of the Hard Lefschetz
    theorem survives for toric hyperkähler varieties. We explain how this implies
    the g-inequalities for rationally representable matroids. We show how the geometrical
    intuition in the first proof, coupled with results of Chari [3], leads to a proof
    of the g-inequalities for general matroid complexes, which is a recent result
    of Swartz [20]. The geometrical idea in the second proof will show that a pure
    O-sequence should satisfy the g-inequalities, thus showing that our result is
    in fact a consequence of a long-standing conjecture of Stanley.

  text: We study an integration theory in circle equivariant cohomology in order to
    prove a theorem relating the cohomology ring of a hyperkähler quotient to the
    cohomology ring of the quotient by a maximal abelian subgroup, analogous to a
    theorem of Martin for symplectic quotients. We discuss applications of this theorem
    to quiver varieties, and compute as an example the ordinary and equivariant cohomology
    rings of a hyperpolygon space.

  text: Large future galaxy cluster surveys, combined with cosmic microwave background
    observations, can achieve a high sensitivity to the masses of cosmologically important
    neutrinos. We show that a weak lensing selected sample of ≳100 000 clusters could
    tighten the current upper bound on the sum of masses of neutrino species by an
    order of magnitude, to a level of 0.03 eV. Since this statistical sensitivity
    is below the best existing lower limit on the mass of at least one neutrino species,
    a future detection is likely, provided that systematic errors can be controlled
    to a similar level.

  text: The z = 10 galaxy recently discovered by Pello and coworkers has a strong
    Lyα emission line that does not appear to have the expected asymmetry with more
    transmission on the red side. The blue wing of a Lyα line originating at high
    redshift should be strongly suppressed by resonant hydrogen absorption along the
    line of sight, an expectation borne out by the observed asymmetric shapes of the
    existing sample of Lyα-emitting sources at lower redshifts (3 < z < 6.7). The
    observed line is inconsistent with the galaxy being embedded in a fully neutral
    intergalactic medium (IGM) and having no receding peculiar velocity relative to
    the surrounding absorbing gas at the 95.0%-98.8% confidence level. Absorption
    on the blue side of the line of the Pello et al. source could be reduced if the
    IGM in the vicinity of the galaxy is highly ionized, but we show that this requires
    an unrealistically high ionizing emissivity. We suggest instead that the Lyα-emitting
    gas is receding relative to the surrounding gas with a velocity of ≳35 km s-1,
    which reduces the inconsistency confidence level to less than 76.0%-94.5%. We
    find that with this velocity shift, the observed strength and shape of the line
    is more consistent with the galaxy being surrounded by its own Strömgren sphere
    embedded in a fully neutral IGM. More generally, we predict that at any given
    redshift, the bright Lyα emitters with broader lines would exhibit stronger asymmetry
    than fainter ones. Bright galaxies with symmetric Lyα lines may be signposts for
    groups and clusters of galaxies, within which they can acquire random velocities
    comparable to or larger than their line widths.

  text: 'Background: Murine leukemia virus (MLV) vector particles can be pseudotyped
    with a truncated variant of the human immunodeficiency virus type 1 (HIV-1) envelope
    protein (Env) and selectively target gene transfer to human cells expressing both
    CD4 and an appropriate co-receptor. Vector transduction mimics the HIV-1 entry
    process and is therefore a safe tool to study HIV-1 entry. Results: Using FLY
    cells, which express the MLV gag and pol genes, we generated stable producer cell
    lines that express the HIV-1 envelope gene and a retroviral vector genome encoding
    the green fluorescent protein (GFP). The BH10 or 89.6 P HIV-1 Env was expressed
    from a bicistronic vector which allowed the rapid selection of stable cell lines.
    A codon-usage-optimized synthetic env gene permitted high, Rev-independent Env
    expression. Vectors generated by these producer cells displayed different sensitivity
    to entry inhibitors. Conclusion: These data illustrate that MLV/HIV-1 vectors
    are a valuable screening system for entry inhibitors or neutralizing antisera
    generated by vaccines.'

  text: We address the problem of recovering a scene recorded through a semireflecting
    medium (i.e. planar lens), with a virtual reflected image being superimposed on
    the image of the scene transmitted through the semirefelecting lens. Recent studies
    propose imaging through a linear polarizer at several orientations to estimate
    the reflected and the transmitted components in the scene. In this study we extend
    the sparse ICA (SPICA) technique and apply it to the problem of separating the
    image of the scene without having any a priori knowledge about its structure or
    statistics. Recent novel advances in the SPICA approach are discussed. Simulation
    and experimental results demonstrate the efficacy of the proposed methods.

  text: "The problem of isometry-invariant representation and comparison of surfaces
    is of cardinal importance in pattern recognition applications dealing with deformable
    objects. Particularly, in three-dimensional face recognition treating facial expressions
    as isometries of the facial surface allows to perform robust recognition insensitive
    to expressions.\r\nIsometry-invariant representation of surfaces can be constructed
    by isometrically embedding them into some convenient space, and carrying out the
    comparison in that space. Presented here is a discussion on isometric embedding
    into S3, which appears to be superior over the previously used Euclidean space
    in sense of the representation accuracy."

  text: "An expression-invariant 3D face recognition approach is presented. Our basic
    assumption is that facial expressions can be modelled as isometries of the facial
    surface. This allows to construct expression-invariant representations of faces
    using the bending-invariant canonical forms approach. The result is an efficient
    and accurate face recognition algorithm, robust to facial expressions, that can
    distinguish between identical twins (the first two authors). We demonstrate a
    prototype system based on the proposed algorithm and compare its performance to
    classical face recognition methods.\r\n\r\nThe numerical methods employed by our
    approach do not require the facial surface explicitly. The surface gradients field,
    or the surface metric, are sufficient for constructing the expression-invariant
    representation of any given face. It allows us to perform the 3D face recognition
    task while avoiding the surface reconstruction stage."

  text: We pose the problem of tissue classification in MRI as a blind source separation
    (BSS) problem and solve it by means of sparse component analysis (SCA). Assuming
    that most MR images can be sparsely represented, we consider their optimal sparse
    representation. Sparse components define a physically-meaningful feature space
    for classification. We demonstrate our approach on simulated and real multi-contrast
    MRI data. The proposed framework is general in that it is applicable to other
    modalities of medical imaging as well, whenever the linear mixing model is applicable.

  text: Recently, it was proven empirically that facial expressions can be modelled
    as isometries, that is, geodesic distances on the facial surface were shown to
    be significantly less sensitive to facial expressions compared to Euclidean ones.
    Based on this assumption, the 3DFACE face recognition system was built. The system
    efficiently computes expression invariant signatures based on isometry-invariant
    representation of the facial surface. One of the crucial steps in the recognition
    system was embedding of the face geometric structure into a Euclidean (flat) space.
    Here, we propose to replace the flat embedding by a spherical one to construct
    isometric invariant representations of the facial image. We refer to these new
    invariants as spherical canonical images. Compared to its Euclidean counterpart,
    spherical embedding leads to notably smaller metric distortion. We demonstrate
    experimentally that representations with lower embedding error lead to better
    recognition. In order to efficiently compute the invariants we introduce a dissimilarity
    measure between the spherical canonical images based on the spherical harmonic
    transform.

  text: The relative Newton algorithm, previously proposed for quasi-maximum likelihood
    blind source separation and blind deconvolution of one-dimensional signals is
    generalized for blind deconvolution of images. Smooth approximation of the absolute
    value is used as the nonlinear term for sparse sources. In addition, we propose
    a method of sparsification, which allows blind deconvolution of arbitrary sources,
    and show how to find optimal sparsifying transformations by supervised learning.

  text: We propose a relative optimization framework for quasi-maximum likelihood
    (QML) blind deconvolution and the relative Newton method as its particular instance.
    Special Hessian structure allows fast Newton system construction and solution,
    resulting in a fast-convergent algorithm with iteration complexity comparable
    to that of gradient methods. We also propose the use of rational infinite impulse
    response (IIR) restoration kernels, which constitute a richer family of filters
    than the traditionally used finite impulse response (FIR) kernels. We discuss
    different choices of nonlinear functions that are suitable for deconvolution of
    super- and sub-Gaussian sources and formulate the conditions under which the QML
    estimation is stable. Simulation results demonstrate the efficiency of the proposed
    methods.

  text: In this correspondence, we consider the problem of multi-input multi output
    (MIMO) quasi maximum likelihood (QML) blind deconvolution. We examine two classes
    of estimators, which are commonly believed to be suitable for super and sub-Gaussian
    sources. We state the consistency conditions and demonstrate a source distribution,
    for which the studied estimators are unsuitable, in the sense that they are inconsistent.

  text: Gravitational lensing can amplify the apparent brightness of distant sources.
    Images that are highly magnified are often part of multiply imaged systems, but
    we consider the possibility of having large magnifications without additional
    detectable images. In rare but nonnegligible situations, lensing can produce a
    single highly magnified image; this phenomenon is mainly associated with massive
    cluster-scale halos (≳1013.5 M☉). Alternatively, lensing can produce multiply
    imaged systems in which the extra images are either unresolved or too faint to
    be detectable. This phenomenon is dominated by galaxies and lower mass halos (≲1012
    M☉) and is very sensitive to the inner density profile of the halos. Although
    we study the general problem, we customize our calculations to four quasars at
    redshift z ≈ 6 in the Sloan Digital Sky Survey (SDSS), for which Richards et al.
    (2004) have ruled out the presence of extra images down to an image splitting
    of Δθ = 0farcs3 and a flux ratio of f = 0.01. We predict that 9%-29% of all z
    ≈ 6 quasars that are magnified by a factor of μ > 10 would lack detectable extra
    images, with 5%-10% being true singly imaged systems. The maximum of 29% is reached
    only in the unlikely event that all low-mass (≲1010 M☉) halos have highly concentrated
    (isothermal) profiles. In more realistic models in which dwarf halos have flatter
    (Navarro-Frenk-White) inner profiles, the maximum probability is ~10%. We conclude
    that the probability that all four SDSS quasars are magnified by a factor of 10
    is ≲10-4. The only escape from this conclusion is if there are many (>10) multiply
    imaged z ≈ 6 quasars in the SDSS database that have not yet been identified, which
    seems unlikely. In other words, lensing cannot explain the brightnesses of the
    z ≈ 6 quasars, and models that invoke lensing to avoid having billion-solar-mass
    black holes in the young universe are not viable.

  text: We discuss currently available observational constraints on the reionization
    history of the intergalactic medium (IGM), and the extent to which accreting black
    holes (BHs) can help explain these observations. We show new evidence, based on
    the combined statistics of Lyman α and β absorption in quasar spectra, that the
    IGM contains a significant amount of neutral hydrogen, and is experiencing rapid
    ionization at redshift z~ 6. However, we argue that quasar BHs, even faint ones
    that are below the detection thresholds of existing optical surveys, are unlikely
    to drive the evolution of the neutral fraction around this epoch, because they
    would over–produce the present–day soft X–ray background. On the other hand, the
    seeds of the z~ 6 quasar BHs likely appeared at much earlier epochs (z~ 20), and
    produced hard ionizing radiation by accretion. These early BHs are promising candidates
    to account for the high redshift (z~ 15) ionization implied by the recent cosmic
    microwave anisotropy data from WMAP. Using a model for the growth of BHs by accretion
    and mergers in a hierarchical cosmology, we suggest that the early growth of quasars
    must include a super-Eddington growth phase, and that, although not yet optically
    identified, the FIRST radio survey may have already detected several thousand
    >108M⊙ BHs at z>6.

  text: An enhanced temperature-index glacier melt model, incorporating incoming shortwave
    radiation and albedo, is presented. The model is an attempt to combine the high
    temporal resolution and accuracy of physically based melt models with the lower
    data requirements and computational simplicity of empirical melt models, represented
    by the ‘degree-day’ method and its variants. The model is run with both measured
    and modelled radiation data, to test its applicability to glaciers with differing
    data availability. Five automatic weather stations were established on Haut Glacier
    d’Arolla, Switzerland, between May and September 2001. Reference surface melt
    rates were calculated using a physically based energy-balance melt model. The
    performance of the enhanced temperature-index model was tested at each of the
    four validation stations by comparing predicted hourly melt rates with reference
    melt rates. Predictions made with three other temperature-index models were evaluated
    in the same way for comparison. The enhanced temperature-index model offers significant
    improvements over the other temperature-index models, and accounts for 90–95%
    of the variation in the reference melt rate. The improvement is lower, but still
    significant, when the model is forced by modelled shortwave radiation data, thus
    offering a better alternative to existing models that require only temperature
    data input.
