text: Morphogens are secreted signalling molecules that act in a graded manner to
control the pattern of cellular differentiation in developing tissues. An example
is Sonic hedgehog (Shh), which acts in several developing vertebrate tissues,
including the central nervous system, to provide positional information during
embryonic patterning. Here we address how Shh signalling assigns the positional
identities of distinct neuronal subtype progenitors throughout the ventral neural
tube. Assays of intracellular signal transduction and gene expression indicate
that the duration as well as level of signalling is critical for morphogen interpretation.
Progenitors of the ventral neuronal subtypes are established sequentially, with
progressively more ventral identities requiring correspondingly higher levels
and longer periods of Shh signalling. Moreover, cells remain sensitive to changes
in Shh signalling for an extended time, reverting to antecedent identities if
signalling levels fall below a threshold. Thus, the duration of signalling is
important not only for the assignment but also for the refinement and maintenance
of positional identity. Together the data suggest a dynamic model for ventral
neural tube patterning in which positional information corresponds to the time
integral of Shh signalling. This suggests an alternative to conventional models
of morphogen action that rely solely on the level of signalling.

text: The epitaxial growth of germanium on silicon leads to the self-assembly of
SiGe nanocrystals by a process that allows the size, composition and position
of the nanocrystals to be controlled. This level of control, combined with an
inherent compatibility with silicon technology, could prove useful in nanoelectronic
applications. Here, we report the confinement of holes in quantum-dot devices
made by directly contacting individual SiGe nanocrystals with aluminium electrodes,
and the production of hybrid superconductor- semiconductor devices, such as resonant
supercurrent transistors, when the quantum dot is strongly coupled to the electrodes.
Charge transport measurements on weakly coupled quantum dots reveal discrete energy
spectra, with the confined hole states displaying anisotropic gyromagnetic factors
and strong spin-orbit coupling with pronounced dependences on gate voltage and
magnetic field.

text: We investigate electronic transport in n-i-n GaN nanowires with and without
AlN double barriers. The nanowires are grown by catalyst-free, plasma-assisted
molecular beam epitaxy enabling abrupt GaN/AlN interfaces as well as longitudinal
n-type doping modulation. At low temperature, transport in n-i-n GaN nanowires
is dominated by the Coulomb blockade effect. Carriers are confined in the undoped
middle region, forming single or multiple islands with a characteristic length
of ∼100 nm. The incorporation of two AlN tunnel barriers causes confinement to
occur within the GaN dot in between. In the case of a 6 nm thick dot and 2 nm
thick barriers, we observe characteristic signatures of Coulomb-blockaded transport
in single quantum dots with discrete energy states. For thinner dots and barriers,
Coulomb-blockade effects do not play a significant role while the onset of resonant
tunneling via the confined quantum levels is accompanied by a negative differential
resistance surviving up to ∼150 K.

text: It has been proposed that primordial gas in early dark matter halos, with
virial temperatures above 10^4 K, can avoid fragmentation and undergo rapid collapse,
possibly resulting in a supermassive black hole (SMBH). This requires the gas
to avoid cooling and to remain at temperatures near T=10^4 K. We show that this
condition can be satisfied in the presence of a sufficiently strong primordial
magnetic field, which heats the collapsing gas via ambipolar diffusion. If the
field has a strength above B = 3.6 (comoving) nG, the collapsing gas is kept warm
(T=10^4K) until it reaches the critical density n_crit=10^3 cm^{-3} at which the
roto-vibrational states of H_2 approach local thermodynamic equilibrium. H_2-cooling
then remains inefficient, and the gas temperature stays near 10^4K, even as it
continues to collapse to higher densities. The critical magnetic field strength
required to permanently suppress H_2-cooling is somewhat higher than upper limit
of approx. 2 nG from the cosmic microwave background (CMB). However, it can be
realized in the rare (2-3)-sigma regions of the spatially fluctuating B-field;
these regions contain a sufficient number of halos to account for the z=6 quasar
BHs.

text: In the absence of H_2 molecules, the primordial gas in early dark matter halos
with virial temperatures just above T_vir >~ 10^4 K cools by collisional excitation
of atomic H. Although it cools efficiently, this gas remains relatively hot, at
a temperature near T ~ 8000 K, and consequently might be able to avoid fragmentation
and collapse directly into a supermassive black hole (SMBH). In order for H_2--formation
and cooling to be strongly suppressed, the gas must be irradiated by a sufficiently
intense ultraviolet (UV) flux. We performed a suite of three--dimensional hydrodynamical
adaptive mesh refinement (AMR) simulations of gas collapse in three different
protogalactic halos with T_vir >~ 10^4 K, irradiated by a UV flux with various
intensities and spectra. We determined the critical specific intensity, Jcrit,
required to suppress H_2 cooling in each of the three halos. For a hard spectrum
representative of metal--free stars, we find (in units of 10^{-21} erg s^{-1}

text: Supermassive black holes (SMBHs) are common in local galactic nuclei, and
SMBHs as massive as several billion solar masses already exist at redshift z=6.
These earliest SMBHs may arise by the combination of Eddington-limited growth
and mergers of stellar-mass seed BHs left behind by the first generation of metal-free
stars, or by the rapid direct collapse of gas in rare special environments where
the gas can avoid fragmenting into stars. In this contribution, I review these
two competing scenarios. I also briefly mention some more exotic ideas and how
the different models may be distinguished in the future by LISA and other instruments.

text: Finding electromagnetic (EM) counterparts of future gravitational wave (GW)
sources would bring rich scientific benefits. A promising possibility, in the
case of the coalescence of a supermassive black hole binary (SMBHB), is that the
prompt emission from merger-induced disturbances in a supersonic circumbinary
disc may be detectable. We follow the post-merger evolution of a thin, zero-viscosity
circumbinary gas disc with two-dimensional simulations, using the hydrodynamic
code flash. We analyse perturbations arising from the 530 km s−1 recoil of a 106
M⊙ binary, oriented in the plane of the disc, assuming either a non-radiative
gamma-law or a pseudo-isothermal equation of state for the gas. We find that a
single-armed spiral shock wave forms and propagates outwards, sweeping up ∼40
per cent of the mass of the disc. The morphology and evolution of the perturbations
agrees well with those of caustics predicted to occur in a collisionless disc.
Assuming that the disc radiates nearly instantaneously to maintain a constant
temperature, we estimate the amount of dissipation and corresponding post-merger
light curve. The luminosity rises steadily on the time-scale of months, and reaches
few ×1043 erg s−1, corresponding to ≈10 per cent of the Eddington luminosity of
the central SMBHB. We also analyse the case in which gravitational wave emission
results in a 5 per cent mass loss in the merger remnant. The mass loss reduces
the shock overdensities and the overall luminosity of the disc by ≈15–20 per cent,
without any other major effects on the spiral shock pattern.

text: The coalescence of a supermassive black hole binary (SMBHB) is thought to
be accompanied by an electromagnetic (EM) afterglow, produced by the viscous infall
of the surrounding circumbinary gas disk after the merger. It has been proposed
that once the merger has been detected in gravitational waves (GWs) by LISA, follow-up
EM searches for this afterglow can help identify the EM counterpart of the LISA
source. Here we study whether the afterglows may be sufficiently bright and numerous
to be detectable in EM surveys alone. The viscous afterglow, which lasts for years
to decades for SMBHBs in LISA's sensitivity window, is characterized by rapid
increases in both the bolometric luminosity and in the spectral hardness of the
source. If quasar activity is triggered by the same major galaxy mergers that
produce SMBHBs, then the afterglow could be interpreted as a signature of the
birth of a quasar. Using an idealized model for the post-merger viscous spreading
of the circumbinary disk and the resulting light curve, and using the observed
luminosity function of quasars as a proxy for the SMBHB merger rate, we delineate
the survey requirements for identifying such birthing quasars. If circumbinary
disks have a high disk surface density and viscosity, an all-sky soft X-ray survey
with a sensitivity of ~<3x10^-14 erg s^-1 cm^-2 and a time resolution of ~months
could identify dozens of birthing quasars with sustained brightening rates of
>10%/yr. If >1% of the X-ray emission is reprocessed into optical frequencies,
birthing quasars could also be identified in optical transient surveys such as
the LSST. Distinguishing a birthing quasar from other variable sources may be
facilitated by the monotonic hardening of its spectrum, but will likely remain
challenging. This reinforces the notion that joint EM-plus-GW observations offer
the best prospects for identifying the EM signatures of SMBHB mergers.

text: Clusters of galaxies have been extensively used to determine cosmological
parameters. A major difficulty in making the best use of Sunyaev–Zel'dovich (SZ)
and X-ray observations of clusters for cosmology is that using X-ray observations
it is difficult to measure the temperature distribution and therefore determine
the density distribution in individual clusters of galaxies out to the virial
radius. Observations with the new generation of SZ instruments are a promising
alternative approach. We use clusters of galaxies drawn from high-resolution adaptive
mesh refinement cosmological simulations to study how well we should be able to
constrain the large-scale distribution of the intracluster gas (ICG) in individual
massive relaxed clusters using AMiBA in its configuration with 13 1.2 m diameter
dishes (AMiBA13) along with X-ray observations. We show that non-isothermal β
models provide a good description of the ICG in our simulated relaxed clusters.
We use simulated X-ray observations to estimate the quality of constraints on
the distribution of gas density, and simulated SZ visibilities (AMiBA13 observations)
for constraints on the large-scale temperature distribution of the ICG. We find
that AMiBA13 visibilities should constrain the scale radius of the temperature
distribution to about 50% accuracy. We conclude that the upgraded AMiBA, AMiBA13,
should be a powerful instrument to constrain the large-scale distribution of the
ICG.

text: We propose counting peaks in weak lensing (WL) maps, as a function of their
height, to probe models of dark energy and to constrain cosmological parameters.
Because peaks can be identified in two-dimensional WL maps directly, they can
provide constraints that are free from potential selection effects and biases
involved in identifying and determining the masses of galaxy clusters. We have
run cosmological N-body simulations to produce WL convergence maps in three models
with different constant values of the dark energy equation of state parameter,
w=-0.8, -1, and -1.2, with a fixed normalization of the primordial power spectrum
(corresponding to present-day normalizations of sigma8=0.742, 0.798, and 0.839,
respectively). By comparing the number of WL peaks in 8 convergence bins in the
range of -0.1 < kappa < 0.2, in multiple realizations of a single simulated 3x3
degree field, we show that the first (last) pair of models can be distinguished
at the 95% (85%) confidence level. A survey with depth and area (20,000 sq. degrees),
comparable to those expected from LSST, should have a factor of approx. 50 better
parameter sensitivity. We find that relatively low-amplitude peaks (kappa = 0.03),
which typically do not correspond to a single collapsed halo along the line of
sight, account for most of this sensitivity. We study a range of smoothing scales
and source galaxy redshifts (z_s). With a fixed source galaxy density of 15/arcmin^2,
the best results are provided by the smallest scale we can reliably simulate,
1 arcminute, and z_s=2 provides substantially better sensitivity than z_s< 1.5.

text: We present the realization of a cavity quantum electrodynamics setup in which
photons of strongly different lifetimes are engineered in different harmonic modes
of the same cavity. We achieve this in a superconducting transmission line resonator
with superconducting qubits coupled to the different modes. One cavity mode is
strongly coupled to a detection line for qubit state readout, while a second long
lifetime mode is used for photon storage and coherent quantum operations. We demonstrate
sideband-based measurement of photon coherence, generation of n photon Fock states
and the scaling of the sideband Rabi frequency with √n using a scheme that may
be extended to realize sideband-based two-qubit logic gates.

text: The quantum properties of electromagnetic, mechanical or other harmonic oscillators
can be revealed by investigating their strong coherent coupling to a single quantum
two level system in an approach known as cavity quantum electrodynamics (QED).
At temperatures much lower than the characteristic energy level spacing the observation
of vacuum Rabi oscillations or mode splittings with one or a few quanta asserts
the quantum nature of the oscillator. Here, we study how the classical response
of a cavity QED system emerges from the quantum one when its thermal occupation-or
effective temperature-is raised gradually over 5 orders of magnitude. In this
way we explore in detail the continuous quantum-to-classical crossover and demonstrate
how to extract effective cavity field temperatures from both spectroscopic and
time-resolved vacuum Rabi measurements.

text: A number of superconducting qubits, such as the transmon or the phase qubit,
have an energy level structure with small anharmonicity. This allows for convenient
access of higher excited states with similar frequencies. However, special care
has to be taken to avoid unwanted higher-level populations when using short control
pulses. Here we demonstrate the preparation of arbitrary three level superposition
states using optimal control techniques in a transmon. Performing dispersive readout,
we extract the populations of all three levels of the qutrit and study the coherence
of its excited states. Finally we demonstrate full quantum state tomography of
the prepared qutrit states and evaluate the fidelities of a set of states, finding
on average 95%.

text: Retinitis pigmentosa refers to a diverse group of hereditary diseases that
lead to incurable blindness, affecting two million people worldwide. As a common
pathology, rod photoreceptors die early, whereas light-insensitive, morphologically
altered cone photoreceptors persist longer. It is unknown if these cones are accessible
for therapeutic intervention. Here, we show that expression of archaebacterial
halorhodopsin in light-insensitive cones can substitute for the native phototransduction
cascade and restore light sensitivity in mouse models of retinitis pigmentosa.
Resensitized photoreceptors activate all retinal cone pathways, drive sophisticated
retinal circuit functions (including directional selectivity), activate cortical
circuits, and mediate visually guided behaviors. Using human ex vivo retinas,
we show that halorhodopsin can reactivate light-insensitive human photoreceptors.
Finally, we identified blind patients with persisting, light-insensitive cones
for potential halorhodopsin-based therapy.

text: The effect of the partial antiaromaticity of biphenylene on its substitution
chemistry, its oxidation potential, and its single-molecule conductance is explored.
Biphenylene and fluorene molecules with linkers of two amino groups or two cyclic
thioether groups were synthesized and their conduction properties were investigated
using scanning tunneling microscopy (STM) break-junction techniques and DFT calculations.
Despite the partial antiaromaticity of biphenylene, which causes the biphenylenes
to be much more easily oxidizable, no significant increase in molecular conductance
was found.

text: We measure the conductance of single Au−molecule−Au junctions with a series
of air-stable diphenylphosphine-terminated molecules using the scanning tunneling
microscope-based break junction technique. Thousands of conductance versus displacement
traces collected for each molecule are used to statistically analyze junction
conductance and evolution upon elongation. Measured conductances for a series
of alkane-based molecules exhibit an exponential decrease with increasing length,
as expected for saturated molecules, with a tunneling decay constant of 0.98 ±
0.04. Measurements of junction elongation indicate strong metal−molecule binding,
with a length that increases with the number of methylene groups in the backbone.
Measured conductance histograms for four molecules with short, unsaturated backbones
(e.g., benzene) are much broader with less well-defined peaks. These measurements
are supported by density function theory calculations. The phosphine binds selectively
to under-coordinated gold atoms through a donor−acceptor bond with a binding energy
of about 1 eV. The calculated tunnel coupling correlates very well with experiment.

text: Using photoemission spectroscopy, we determine the relationship between electronic
energy level alignment at a metal−molecule interface and single-molecule junction
transport data. We measure the position of the highest occupied molecular orbital
(HOMO) relative to the Au metal Fermi level for three 1,4-benzenediamine derivatives
on Au(111) and Au(110) with ultraviolet and resonant X-ray photoemission spectroscopy.
We compare these results to scanning tunnelling microscope-based break-junction
measurements of single molecule conductance and to first-principles calculations.
We find that the energy difference between the HOMO and Fermi level for the three
molecules adsorbed on Au(111) correlate well with changes in conductance and agree
well with quasiparticle energies computed from first-principles calculations incorporating
self-energy corrections. On the Au(110) that presents Au atoms with lower-coordination,
critical in break-junction conductance measurements, we see that the HOMO level
shifts further from the Fermi level. These results provide the first direct comparison
of spectroscopic energy level alignment measurements with single molecule junction
transport data.

text: We have measured the conductance and characterized molecule−electrode binding
geometries of four pyridine-terminated molecules by elongating and then compressing
gold point contacts in a solution of molecules. We have found that all pyridine-terminated
molecules exhibit bistable conductance signatures, signifying that the nature
of the pyridine−gold bond allows two distinct conductance states that are accessed
as the gold−molecule−gold junction is elongated. We have identified the low-conductance
state as corresponding to a molecule fully stretched out between the gold electrodes,
where the distance between contacts correlates with the length of the molecule;
the high-conductance state is due to a molecule bound at an angle. For all molecules,
we have found that the distribution of junction elongations in the low-conductance
state is the same, while in the high-conductance state, the most likely elongation
length increases linearly with molecule length. The results of first-principles
conductance calculations for the four molecules in the low-conductance geometry
agree well with the experimental results and show that the dominant conducting
channel in the conjugated pyridine-linked molecules is through the π* orbital.

text: Invariant image descriptors play an important role in many computer vision
and pattern recognition problems such as image search and retrieval. A dominant
paradigm today is that of “bags of features”, a representation of images as distributions
of primitive visual elements. The main disadvantage of this approach is the loss
of spatial relations between features, which often carry important information
about the image. In this paper, we show how to construct spatially-sensitive image
descriptors in which both the features and their relation are affine-invariant.
Our construction is based on a vocabulary of pairs of features coupled with a
vocabulary of invariant spatial relations between the features. Experimental results
show the advantage of our approach in image retrieval applications.

text: Automatic detection of symmetries, regularity, and repetitive structures in
3D geometry is a fundamental problem in shape analysis and pattern recognition
with applications in computer vision and graphics. Especially challenging is to
detect intrinsic regularity, where the repetitions are on an intrinsic grid, without
any apparent Euclidean pattern to describe the shape, but rising out of (near)
isometric deformation of the underlying surface. In this paper, we employ multidimensional
scaling to reduce the problem of intrinsic structure detection to a simpler problem
of 2D grid detection. Potential 2D grids are then identified using an autocorrelation
analysis, refined using local fitting, validated, and finally projected back to
the spatial domain. We test the detection algorithm on a variety of scanned plaster
models in presence of imperfections like missing data, noise and outliers. We
also present a range of applications including scan completion, shape editing,
super-resolution, and structural correspondence.
