text: Krstic has carried out the first quantum mechanical calculations near threshold
for the charge transfer (CT) process H^+ + H_2(X ^1Sigma_g^+, nu=0, J=0) --> H(1s)
+ H_2^+. These results are relevant for models of primordial galaxy and first
star formation that require reliable atomic and molecular data for obtaining the
early universe hydrogen chemistry. Using the results of Krstic, we calculate the
relevant CT rate coefficient for temperatures between 100 and 30,000 K. We also
present a simple fit which can be readily implemented into early universe chemical
models. Additionally, we explore how the range of previously published data for
this reaction translates into uncertainties in the predicted gas temperature and
H_2 relative abundance in a collapsing primordial gas cloud. Our new data significantly
reduce these cosmological uncertainties that are due to the uncertainties in the
previously published CT rate coefficients.

text: Recent studies have suggested that during their coalescence, binary supermassive
black holes (SMBHs) experience typical gravitational recoil velocities that may
be as large as ≳100 km s^-1. These velocities exceed the escape velocity vesc
from typical dark matter (DM) halos at high redshift (z ≳ 6), and therefore put
constraints on scenarios in which early SMBHs grow at the centers of DM halos.
Here we quantify these constraints for the most distant known SMBH, with an inferred
mass in excess of 10^9 M☉, powering the bright quasar SDSS J1148+5251 discovered
in the Sloan Digital Sky Survey at z = 6.43. We assume that this SMBH grew via
a combination of accretion and mergers between preexisting seed BHs in individual
progenitor halos, and that mergers between progenitors with vesc < vkick disrupt
the BH growth process. Our results suggest that under these assumptions, the z
≈ 6 SMBHs had a phase during which they gained mass vary rapidly. In particular,
typical z ≈ 3 quasars with luminosities similar to that of SDSS J1148+5251 have
recently been inferred to have an average radiative efficiency of epsilon ≈ 20%.
The growth rate of the SMBH in SDSS J1148+5251 must have significantly exceeded
the Eddington accretion rate with this efficiency.

text: "We show that the abundance and redshift distribution (\U0001D451\U0001D441/\U0001D451\U0001D467)
of galaxy clusters in future high-yield cluster surveys, combined with the spatial
power spectrum [\U0001D443\U0001D450(\U0001D458)] of the same clusters, can place
significant constraints on the evolution of the dark energy equation of state,
\U0001D464=\U0001D464(\U0001D44E). We evaluate the expected errors on \U0001D464\U0001D44E=−\U0001D451\U0001D464/\U0001D451\U0001D44E
and other cosmological parameters using a Fisher matrix approach, and simultaneously
including cluster structure evolution parameters in our analysis. We study three
different types of forthcoming surveys that will identify clusters based on their
x-ray emission (such as DUO, the Dark Universe Observatory), their Sunyaev-Zel'dovich
(SZ) decrement (such as SPT, the South Pole Telescope), or their weak-lensing
shear (such as LSST, the Large Synoptic Survey Telescope). We find that combining
the cluster abundance and power spectrum significantly enhances constraints from
either method alone. We show that the weak-lensing survey can deliver a constraint
as tight as \U0001D6E5\U0001D464\U0001D44E∼0.1 on the evolution of the dark energy
equation of state, and that the x-ray and SZ surveys each yield \U0001D6E5\U0001D464\U0001D44E∼0.4
separately, or \U0001D6E5\U0001D464\U0001D44E∼0.2 when these two surveys are
combined. For the x-ray and SZ surveys, constraints on dark energy parameters
are improved by a factor of 2 by combining the cluster data with cosmic microwave
background anisotropy measurements by Planck, but degrade by a factor of 2 if
the survey is required to solve simultaneously for cosmological and cluster structure
evolution parameters. The constraint on \U0001D464\U0001D44E from the weak-lensing
survey is improved by ∼25% with the addition of Planck data."

text: 'We discuss a simple model for the growth of supermassive black holes (BHs)
at the center of spheroidal stellar systems. In particular, we assess the hypotheses
that (1) star formation in spheroids and BH fueling are proportional to one another,
and (2) the BH accretion luminosity stays near the Eddington limit during luminous
quasar phases. With the aid of this simple model, we are able to interpret many
properties of the QSO luminosity function, including the puzzling steep decline
of the characteristic luminosity from redshift z=2 to to z=0: indeed the residual
star formation in spheroidal systems is today limited to a small number of bulges,
characterized by stellar velocity dispersions a factor of 2-3 smaller those of
the elliptical galaxies hosting QSOs at z > 2. A simple consequence of our hypotheses
is that the redshift evolution of the QSO emissivity and of the star formation
history in spheroids should be roughly parallel. We find this result to be broadly
consistent with our knowledge of the evolution of both the global star formation
rate, and of the evolution of the QSO emissivity, but we identify interesting
discrepancies at both low and high redshifts, to which we offer tentative solutions.
Finally, our hypotheses allow us to present a robust method to derive the duty
cycle of QSO activity, based on the observed QSO luminosity function, and on the
present-day relation between the masses of supermassive BHs and those of their
spheroidal host stellar systems. The duty cycle is found to be substantially less
than unity, with characteristic values in the range (3-6)x10^(-3), and we compute
that the average bolometric radiative efficiency is epsilon=0.07. Finally, we
find that the growth in mass of individual black holes at high redshift (z>2)
can be dominated by mergers, and is therefore not necessarily limited by accretion.'

text: Over the last few years, the Sloan Digital Sky Survey (SDSS) has discovered
several hundred quasars with redshift between 4.0 and 6.4. Including the effects
of magnification bias, one expects a priori that an appreciable fraction of these
objects are gravitationally lensed. We have used the Advanced Camera for Surveys
on the Hubble Space Telescope to carry out a snapshot imaging survey of high-redshift
SDSS quasars to search for gravitationally split lenses. This paper, the first
in a series reporting the results of the survey, describes snapshot observations
of four quasars at z = 5.74, 5.82, 5.99, and 6.30, respectively. We find that
none of these objects has a lensed companion within 5 mag with a separation larger
than 0farcs3; within 2.5 mag we can rule out companions within 0farcs1. Based
on the nondetection of strong lensing in these four systems, we constrain the
z ∼ 6 luminosity function to a slope of β > -4.63 (3 σ), assuming a break in the
quasar luminosity function at M = -24.1. We discuss the implications of this constraint
on the ionizing background due to quasars in the early universe. Given that these
quasars are not highly magnified, estimates of the masses of their central engines
by the Eddington argument must be taken seriously, possibly challenging models
of black hole formation.

text: A population of black holes (BHs) at high redshifts (z ≳ 6) that contributes
significantly to the ionization of the intergalactic medium (IGM) would be accompanied
by the copious production of hard (≳10 keV) X-ray photons. The resulting hard
X-ray background would redshift and be observed as a present-day soft X-ray background
(SXB). Under the hypothesis that BHs are the main producers of reionizing photons
in the high-redshift universe, we calculate their contribution to the present-day
SXB. We find that accreting BHs with a hard spectrum (be it luminous quasars or
their lower mass "miniquasar" counterparts) could not fully reionize the universe
without saturating the unresolved component of the 0.5-2 keV SXB at the ≥2 σ level.
Distant miniquasars that produce enough X-rays to only partially ionize the IGM
to a level of at most xe ~ 50% saturate the unresolved SXB by ≲1 σ. Improved determinations
of the unresolved component of the SXB can provide a powerful constraint on the
contribution of accreting BHs to partial or full reionization.

text: A remarkable result of the Wilkinson Microwave Anisotropy Probe (WMAP) observations
is that the universe was significantly reionized at large redshifts. The standard
explanation is that massive stars formed early and reionized the universe around
redshift z ≈ 17. Here we explore an alternative possibility in which the universe
was reionized in two steps. An early boost of reionization is provided by a decaying
sterile neutrino whose decay products, relativistic electrons, result in partial
ionization of the smooth gas. We demonstrate that a neutrino with a mass of mν
~ 200 MeV and a decay time of t ~ 4 × 1015 s can account for the electron scattering
optical depth τ ≈ 0.16 measured by WMAP without violating existing astrophysical
limits on the cosmic microwave and gamma-ray backgrounds. Reionization is then
completed by subsequent star formation at lower redshifts. This scenario alleviates
constraints on structure formation models with reduced small-scale power, such
as those with a running or tilted scalar index, or warm dark matter models.

text: "Recently, a 3D face recognition approach based on geometric invariant signatures,
has been proposed. The key idea is a representation of the facial surface, invariant
to isometric deformations, such as those resulting from facial expressions. One
important stage in the construction of the geometric invariants involves in measuring
geodesic distances on triangulated surfaces, which is carried out by the fast
marching on triangulated domains algorithm.\r\n\r\nProposed here is a method that
uses only the metric tensor of the surface for geodesic distance computation.
That is, the explicit integration of the surface in 3D from its gradients is not
needed for the recognition task. It enables the use of simple and cost-efficient
3D acquisition techniques such as photometric stereo. Avoiding the explicit surface
reconstruction stage saves computational time and reduces numerical errors."

text: Presented here is a generalization of the modified relative Newton method,
recently proposed in [1] for quasi-maximum likelihood blind source separation.
Special structure of the Hessian matrix allows to perform block-coordinate Newton
descent, which significantly reduces the algorithm computational complexity and
boosts its performance. Simulations based on artificial and real data show that
the separation quality using the proposed algorithm outperforms other accepted
blind source separation methods.

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 in modelling the log probability density function, which is suitable
for sparse sources. We propose a method of sparsification, which allows blind
deconvolution of sources with arbitrary distribution, and show how to find optimal
sparsifying transformations by training.

text: We propose a relative optimization framework for quasi maximum likelihood
blind deconvolution and the relative Newton method as its particular instance.
Special Hessian structure allows its fast approximate construction and inversion
with complexity comparable to that of gradient methods. The use of rational IIR
restoration kernels provides a richer family of filters than the traditionally
used FIR kernels. Smoothed absolute value and the smoothed deadzone functions
allow accurate and robust deconvolution of super- and sub-Gaussian sources, respectively.
Simulation results demonstrate the efficiency of the proposed methods.

text: Blind deconvolution is considered as a problem of quasi maximum likelihood
(QML) estimation of the restoration kernel. Simple closed-form expressions for
the asymptotic estimation error are derived. The asymptotic performance bounds
coincide with the Cramér-Rao bounds, when the true ML estimator is used. Conditions
for asymptotic stability of the QML estimator are derived. Special cases when
the estimator is super-efficient are discussed.

text: Presented here is a block-coordinate version of the relative Newton method,
recently proposed for quasi-maximum likelihood blind source separation. Special
structure of the Hessian matrix allows performing block-coordinate Newton descent
efficiently. Simulations show that typically our method converges in near constant
number of iterations (order of 10) independently of the problem size.

text: We discuss the synthesis between the 3D and the 2D data in three-dimensional
face recognition. We show how to compensate for the illumination and racial expressions
using the 3D facial geometry and present the approach of canonical images, which
allows us to incorporate geometric information into standard face recognition
approaches.

text: The writhing number measures the global geometry of a closed space curve or
knot. We show that this measure is related to the average winding number of its
Gauss map. Using this relationship, we give an algorithm for computing the writhing
number for a polygonal knot with n edges in time roughly proportional to n(1.6).
We also implement a different, simple algorithm and provide experimental evidence
for its practical efficiency.

text: We combine topological and geometric methods to construct a multiresolution
representation for a function over a two-dimensional domain. In a preprocessing
stage, we create the Morse-Smale complex of the function and progressively simplify
its topology by cancelling pairs of critical points. Based on a simple notion
of dependency among these cancellations, we construct a hierarchical data structure
supporting traversal and reconstruction operations similarly to traditional geometry-based
representations. We use this data structure to extract topologically valid approximations
that satisfy error bounds provided at runtime.

text: Given a Morse function f over a 2-manifold with or without boundary, the Reeb
graph is obtained by contracting the connected components of the level sets to
points. We prove tight upper and lower bounds on the number of loops in the Reeb
graph that depend on the genus, the number of boundary components, and whether
or not the 2-manifold is orientable. We also give an algorithm that constructs
the Reeb graph in time O(n log n), where n is the number of edges in the triangulation
used to represent the 2-manifold and the Morse function.

text: The two actin-related subunits of the Arp2/3 complex, Arp2 and Arp3, are proposed
to form a pseudo actin dimer that nucleates actin polymerization. However, in
the crystal structure of the inactive complex, they are too far apart to form
such a nucleus. Here, we show using EM that yeast and bovine Arp2/3 complexes
exist in a distribution among open, intermediate and closed conformations. The
crystal structure docks well into the open conformation. The activator WASp binds
at the cleft between Arp2 and Arp3, and all WASp-bound complexes are closed. The
inhibitor coronin binds near the p35 subunit, and all coronin-bound complexes
are open. Activating and loss-of-function mutations in the p35 subunit skew conformational
distribution in opposite directions, closed and open, respectively. We conclude
that WASp stabilizes p35-dependent closure of the complex, holding Arp2 and Arp3
closer together to nucleate an actin filament.
