text: 'Two key processes are in the basis of morphogenesis: the spatial allocation
of cell types in fields of naïve cells and the regulation of growth. Both are
controlled by morphogens, which activate target genes in the growing tissue in
a concentration-dependent manner. Thus the morphogen model is an intrinsically
quantitative concept. However, quantitative studies were performed only in recent
years on two morphogens: Bicoid and Decapentaplegic. This review covers quantitative
aspects of the formation and precision of the Decapentaplegic morphogen gradient.
The morphogen gradient concept is transitioning from a soft definition to a precise
idea of what the gradient could really do.'

text: We study the mechanics of tissue growth via cell division and cell death (apoptosis).
The rearrangements of cells can on large scales and times be captured by a continuum
theory which describes the tissue as an effective viscous material with active
stresses generated by cell division. We study the effects of anisotropies of cell
division on cell rearrangements and show that average cellular trajectories exhibit
anisotropic scaling behaviors. If cell division and apoptosis balance, there is
no net growth, but for anisotropic cell division the tissue undergoes spontaneous
shear deformations. Our description is relevant for the study of developing tissues
such as the imaginal disks of the fruit fly Drosophila melanogaster, which grow
anisotropically.

text: When strained Stranski-Krastanow islands are used as "self-assembled
quantum dots," a key goal is to control the island position. Here we show
that nanoscale grooves can control the nucleation of epitaxial Ge islands on Si(001),
and can drive lateral motion of existing islands onto the grooves, even when the
grooves are very narrow and shallow compared to the islands. A position centered
on the groove minimizes energy. We use as prototype grooves the trenches which
form naturally around islands. During coarsening, the shrinking islands move laterally
to sit directly astride that trench. In subsequent growth, we demonstrate that
islands nucleate on the "empty trenches" which remain on the surface
after complete dissolution of the original islands.

text: The field of cavity quantum electrodynamics (QED), traditionally studied in
atomic systems, has gained new momentum by recent reports of quantum optical experiments
with solid-state semiconducting and superconducting systems. In cavity QED, the
observation of the vacuum Rabi mode splitting is used to investigate the nature
of matter-light interaction at a quantum-mechanical level. However, this effect
can, at least in principle, be explained classically as the normal mode splitting
of two coupled linear oscillators. It has been suggested that an observation of
the scaling of the resonant atom-photon coupling strength in the Jaynes-Cummings
energy ladder with the square root of photon number n is sufficient to prove that
the system is quantum mechanical in nature. Here we report a direct spectroscopic
observation of this characteristic quantum nonlinearity. Measuring the photonic
degree of freedom of the coupled system, our measurements provide unambiguous
spectroscopic evidence for the quantum nature of the resonant atom-field interaction
in cavity QED. We explore atom-photon superposition states involving up to two
photons, using a spectroscopic pump and probe technique. The experiments have
been performed in a circuit QED set-up, in which very strong coupling is realized
by the large dipole coupling strength and the long coherence time of a superconducting
qubit embedded in a high-quality on-chip microwave cavity. Circuit QED systems
also provide a natural quantum interface between flying qubits (photons) and stationary
qubits for applications in quantum information processing and communication.

text: Quantum theory predicts that empty space is not truly empty. Even in the absence
of any particles or radiation, in pure vacuum, virtual particles are constantly
created and annihilated. In an electromagnetic field, the presence of virtual
photons manifests itself as a small renormalization of the energy of a quantum
system, known as the Lamb shift. We present an experimental observation of the
Lamb shift in a solid-state system. The strong dispersive coupling of a superconducting
electronic circuit acting as a quantum bit (qubit) to the vacuum field in a transmission-line
resonator leads to measurable Lamb shifts of up to 1.4% of the qubit transition
frequency. The qubit is also observed to couple more strongly to the vacuum field
than to a single photon inside the cavity, an effect that is explained by taking
into account the limited anharmonicity of the higher excited qubit states.

text: High quality on-chip microwave resonators have recently found prominent new
applications in quantum optics and quantum information processing experiments
with superconducting electronic circuits, a field now known as circuit quantum
electrodynamics (QED). They are also used as single photon detectors and parametric
amplifiers. Here we analyze the physical properties of coplanar waveguide resonators
and their relation to the materials properties for use in circuit QED. We have
designed and fabricated resonators with fundamental frequencies from 2 to 9 GHz
and quality factors ranging from a few hundreds to a several hundred thousands
controlled by appropriately designed input and output coupling capacitors. The
microwave transmission spectra measured at temperatures of 20 mK are shown to
be in good agreement with theoretical lumped element and distributed element transmission
matrix models. In particular, the experimentally determined resonance frequencies,
quality factors, and insertion losses are fully and consistently explained by
the two models for all measured devices. The high level of control and flexibility
in design renders these resonators ideal for storing and manipulating quantum
electromagnetic fields in integrated superconducting electronic circuits.

text: Proliferating cell populations at steady-state growth often exhibit broad
protein distributions with exponential tails. The sources of this variation and
its universality are of much theoretical interest. Here we address the problem
by asymptotic analysis of the population balance equation. We show that the steady-state
distribution tail is determined by a combination of protein production and cell
division and is insensitive to other model details. Under general conditions this
tail is exponential with a dependence on parameters consistent with experiment.
We discuss the conditions for this effect to be dominant over other sources of
variation and the relation to experiments.

text: Complex I of respiratory chains transfers electrons from NADH to ubiquinone,
coupled to the translocation of protons across the membrane. Two alternative coupling
mechanisms are being discussed, redox-driven or conformation-driven. Using "zero-length"
cross-linking reagent and isolated hydrophilic domains of complex I from Escherichia
coli and Thermus thermophilus, we show that the pattern of cross-links between
subunits changes significantly in the presence of NADH. Similar observations were
made previously with intact purified E. coli and bovine complex I. This indicates
that, upon reduction with NADH, similar conformational changes are likely to occur
in the intact enzyme and in the isolated hydrophilic domain (which can be used
for crystallographic studies). Within intact E. coli complex I, the cross-link
between the hydrophobic subunits NuoA and NuoJ was abolished in the presence of
NADH, indicating that conformational changes extend into the membrane domain,
possibly as part of a coupling mechanism. Unexpectedly, in the absence of any
chemical cross-linker, incubation of complex I with NADH resulted in covalent
cross-links between subunits Nqo4 (NuoCD) and Nqo6 (NuoB), as well as between
Nqo6 and Nqo9. Their formation depends on the presence of oxygen and so is likely
a result of oxidative damage via reactive oxygen species (ROS) induced cross-linking.
In addition, ROS- and metal ion-dependent proteolysis of these subunits (as well
as Nqo3) is observed. Fe-S cluster N2 is coordinated between subunits Nqo4 and
Nqo6 and could be involved in these processes. Our observations suggest that oxidative
damage to complex I in vivo may include not only side-chain modifications but
also protein cross-linking and degradation.

Complex I (NADH:ubiquinone oxidoreductase) is the largest protein complex of bacterial and mitochondrial respiratory chains. The first three-dimensional structure of bacterial complex I in vitrified ice was determined by electron cryo-microscopy and single particle analysis. The structure of the Escherichia coli enzyme incubated with either NAD+ (as a reference) or NADH was calculated to 35 and 39 Å resolution, respectively. The X-ray structure of the peripheral arm of Thermus thermophilus complex I was docked into the reference EM structure. The model obtained indicates that Fe-S cluster N2 is close to the membrane domain interface, allowing for effective electron transfer to membrane-embedded quinone. At the current resolution, the structures in the presence of NAD+ or NADH are similar. Additionally, side-view class averages were calculated for the negatively stained bovine enzyme. The structures of bovine complex I in the presence of either NAD+ or NADH also appeared to be similar. These observations indicate that conformational changes upon reduction with NADH, suggested to occur by a range of studies, are smaller than had been thought previously. The model of the entire bacterial complex I could be built from the crystal structures of subcomplexes using the EM envelope described here.

text: In the bacterium Escherichia coli, the Min proteins oscillate between the
cell poles to select the cell center as division site. This dynamic pattern has
been proposed to arise by self-organization of these proteins, and several models
have suggested a reaction-diffusion type mechanism. Here, we found that the Min
proteins spontaneously formed planar surface waves on a flat membrane in vitro.
The formation and maintenance of these patterns, which extended for hundreds of
micrometers, required adenosine 5′-triphosphate (ATP), and they persisted for
hours. We present a reaction-diffusion model of the MinD and MinE dynamics that
accounts for our experimental observations and also captures the in vivo oscillations.

text: 'Population genetics models show that, under certain conditions, the X chromosome
is expected to be under more efficient selection than the autosomes. This could
lead to ''faster-X evolution'', if a large proportion of mutations are fixed by
positive selection, as suggested by recent studies in Drosophila. We used a multispecies
approach to test this: Muller''s element D, an autosomal arm, is fused to the
ancestral X chromosome in Drosophila pseudoobscura and its sister species, Drosophila
affinis. We tested whether the same set of genes had higher rates of non-synonymous
evolution when they were X-linked (in the D. pseudoobscura/D. affinis comparison)
than when they were autosomal (in Drosophila melanogaster/Drosophila yakuba).
Although not significant, our results suggest this may be the case, but only for
genes under particularly strong positive selection/weak purifying selection. They
also suggest that genes that have become X-linked have higher levels of codon
bias and slower synonymous site evolution, consistent with more effective selection
on codon usage at X-linked sites.'

text: 'This paper presents a novel method for real-time animation of highly-detailed
facial expressions based on a multi-scale decomposition of facial geometry into
large-scale motion and fine-scale details, such as expression wrinkles. Our hybrid
animation is tailored to the specific characteristics of large- and fine-scale
facial deformations: Large-scale deformations are computed with a fast linear
shell model, which is intuitively and accurately controlled through a sparse set
of motion-capture markers or user-defined handle points. Fine-scale facial details
are incorporated using a novel pose-space deformation technique, which learns
the correspondence of sparse measurements of skin strain to wrinkle formation
from a small set of example poses. Our hybrid method features real-time animation
of highly-detailed faces with realistic wrinkle formation, and allows both large-scale
deformations and fine-scale wrinkles to be edited intuitively. Furthermore, our
pose-space representation enables the transfer of facial details to novel expressions
or other facial models.'

text: 'We consider the linear stochastic Cauchy problem dX (t) =AX (t) dt +B dWH
(t), t≥ 0, where A generates a C0-semigroup on a Banach space E, WH is a cylindrical
Brownian motion over a Hilbert space H, and B: H → E is a bounded operator. Assuming
the existence of a unique minimal invariant measure μ∞, let Lp denote the realization
of the Ornstein-Uhlenbeck operator associated with this problem in Lp (E, μ∞).
Under suitable assumptions concerning the invariance of the range of B under the
semigroup generated by A, we prove the following domain inclusions, valid for
1 < p ≤ 2: Image omitted. Here WHk, p (E, μinfin; denotes the kth order Sobolev
space of functions with Fréchet derivatives up to order k in the direction of
H. No symmetry assumptions are made on L p.'

text: 'We present an analytic model of thermal state-to-state rotationally inelastic
collisions of polar molecules in electric fields. The model is based on the Fraunhofer
scattering of matter waves and requires Legendre moments characterizing the “shape”
of the target in the body-fixed frame as its input. The electric field orients
the target in the space-fixed frame and thereby effects a striking alteration
of the dynamical observables: both the phase and amplitude of the oscillations
in the partial differential cross sections undergo characteristic field-dependent
changes that transgress into the partial integral cross sections. As the cross
sections can be evaluated for a field applied parallel or perpendicular to the
relative velocity, the model also offers predictions about steric asymmetry. We
exemplify the field-dependent quantum collision dynamics with the behavior of
the Ne–OCS(Σ1) and Ar–NO(Π2) systems. A comparison with the close-coupling calculations
available for the latter system [Chem. Phys. Lett.313, 491 (1999)] demonstrates
the model’s ability to qualitatively explain the field dependence of all the scattering
features observed.'

text: 'We present the physics of the quantum Zeno effect, whose gist is often expressed
by invoking the adage "a watched pot never boils". We review aspects
of the theoretical and experimental work done on the effect since its inception
in 1977, and mention some applications. We dedicate the article - with our very
best wishes - to Rudolf Zahradnik at the occasion of his great jubilee. Perhaps
Rudolf''s lasting youthfulness and freshness are due to that he himself had been
frequently observed throughout his life: until the political turn-around in 1989
by those who wished, by their surveillance, to prevent Rudolf from spoiling the
youth by his personal culture and his passion for science and things beautiful
and useful in general. This attempt had failed. Out of gratitude, the youth has
infected Rudolf with its youthfulness. Chronically. Since 1989, Rudolf has been
closely watched by the public at large. For the same traits of his as before,
but with the opposite goal and for the benefit of all generations. We relish keeping
him in sight...'

text: Despite the growing geological evidence that fluid boiling and vapour-liquid
separation affect the distribution of metals in magmatic-hydrothermal systems
significantly, there are few experimental data on the chemical status and partitioning
of metals in the vapour and liquid phases. Here we report on an in situ measurement,
using X-ray absorption fine structure (XAFS) spectroscopy, of antimony speciation
and partitioning in the system Sb2O3-H2O-NaCl-HCl at 400°C and pressures 270–300
bar corresponding to the vapour-liquid equilibrium. Experiments were performed
using a spectroscopic cell which allows simultaneous determination of the total
concentration and atomic environment of the absorbing element (Sb) in each phase.
Results show that quantitative vapour-brine separation of a supercritical aqueous
salt fluid can be achieved by a controlled decompression and monitoring the X-ray
absorbance of the fluid phase. Antimony concentrations in equilibrium with Sb2O3
(cubic, senarmontite) in the coexisting vapour and liquid phases and corresponding
SbIII vapour-liquid partitioning coefficients are in agreement with recent data
obtained using batch-reactor solubility techniques. The XAFS spectra analysis
shows that hydroxy-chloride complexes, probably Sb(OH)2Cl0, are dominant both
in the vapour and liquid phase in a salt-water system at acidic conditions. This
first in situ XAFS study of element fractionation between coexisting volatile
and dense phases opens new possibilities for systematic investigations of vapour-brine
and fluid-melt immiscibility phenomena, avoiding many experimental artifacts common
in less direct techniques.

text: We revisit recent work of Heath-Brown on the average order of the quantity
r(L1(x))⋯r(L4(x)), for suitable binary linear forms L1,...,L4, as x=(x1,x2) ranges
over quite general regions in ℤ2. In addition to improving the error term in Heath-Browns
estimate, we generalise his result to cover a wider class of linear forms.
