text: Creating a train of single photons and monitoring its propagation and interaction
is challenging in most physical systems, as photons generally interact very weakly
with other systems. However, when confining microwave frequency photons in a transmission
line resonator, effective photon-photon interactions can be mediated by qubits
embedded in the resonator. Here, we observe the phenomenon of photon blockade
through second-order correlation function measurements. The experiments clearly
demonstrate antibunching in a continuously pumped source of single microwave photons
measured by using microwave beam splitters, linear amplifiers, and quadrature
amplitude detectors. We also investigate resonance fluorescence and Rayleigh scattering
in Mollow-triplet-like spectra.

text: Continuous variable entanglement between two modes of a radiation field is
usually studied at optical frequencies. Here we demonstrate experiments that show
the entanglement between microwave photons of different energy in a broadband
squeezed beam. We use a Josephson parametric amplifier to generate the two-mode
correlated state and detect all four quadrature components simultaneously in a
two-channel heterodyne setup using amplitude detectors. Analyzing two-dimensional
phase space histograms for all possible pairs of quadratures allows us to determine
the full covariance matrix, which is in good agreement with the one expected for
a two-mode squeezed state.

text: Microwave cavities with high quality factors enable coherent coupling of distant
quantum systems. Virtual photons lead to a transverse interaction between qubits
when they are nonresonant with the cavity but resonant with each other. We experimentally
investigate the inverse scaling of the interqubit coupling with the detuning from
a cavity mode and its proportionality to the qubit-cavity interaction strength.
We demonstrate that the enhanced coupling at higher frequencies is mediated by
multiple higher-harmonic cavity modes. Moreover, we observe dark states of the
coupled qubit-qubit system and analyze their relation to the symmetry of the applied
driving field at different frequencies.

text: Many membrane channels and receptors exhibit adaptive, or desensitized, response
to a strong sustained input stimulus, often supported by protein activity-dependent
inactivation. Adaptive response is thought to be related to various cellular functions
such as homeostasis and enlargement of dynamic range by background compensation.
Here we study the quantitative relation between adaptive response and background
compensation within a modeling framework. We show that any particular type of
adaptive response is neither sufficient nor necessary for adaptive enlargement
of dynamic range. In particular a precise adaptive response, where system activity
is maintained at a constant level at steady state, does not ensure a large dynamic
range neither in input signal nor in system output. A general mechanism for input
dynamic range enlargement can come about from the activity-dependent modulation
of protein responsiveness by multiple biochemical modification, regardless of
the type of adaptive response it induces. Therefore hierarchical biochemical processes
such as methylation and phosphorylation are natural candidates to induce this
property in signaling systems.

text: The Levene model is the simplest mathematical model to describe the evolution
of gene frequencies in spatially subdivided populations. It provides insight into
how locally varying selection promotes a population’s genetic diversity. Despite
its simplicity, interesting problems have remained unsolved even in the diallelic
case. In this paper we answer an open problem by establishing that for two alleles
at one locus and J demes, up to 2J−1 polymorphic equilibria may coexist. We first
present a proof for the case of stable monomorphisms and then show that the result
also holds for protected alleles. These findings allow us to prove that any odd
number (up to 2J−1) of equilibria is possible, before we extend the proof to even
numbers. We conclude with some numerical results and show that for J>2, the
proportion of parameter space affording this maximum is extremely small.

text: Complex I is the first and largest enzyme of the respiratory chain, coupling
electron transfer between NADH and ubiquinone to the translocation of four protons
across the membrane. It has a central role in cellular energy production and has
been implicated in many human neurodegenerative diseases. The L-shaped enzyme
consists of hydrophilic and membrane domains. Previously, we determined the structure
of the hydrophilic domain. Here we report the crystal structure of the Esherichia
coli complex I membrane domain at 3.0 Ã. resolution. It includes six subunits,
NuoL, NuoM, NuoN, NuoA, NuoJ and NuoK, with 55 transmembrane helices. The fold
of the homologous antiporter-like subunits L, M and N is novel, with two inverted
structural repeats of five transmembrane helices arranged, unusually, face-to-back.
Each repeat includes a discontinuous transmembrane helix and forms half of a channel
across the membrane. A network of conserved polar residues connects the two half-channels,
completing the proton translocation pathway. Unexpectedly, lysines rather than
carboxylate residues act as the main elements of the proton pump in these subunits.
The fourth probable proton-translocation channel is at the interface of subunits
N, K, J and A. The structure indicates that proton translocation in complex I,
uniquely, involves coordinated conformational changes in six symmetrical structural
elements.

text: Complex I is the first enzyme of the respiratory chain and plays a central
role in cellular energy production. It has been implicated in many human neurodegenerative
diseases, as well as in ageing. One of the biggest membrane protein complexes,
it is an L-shaped assembly consisting of hydrophilic and membrane domains. Previously,
we have determined structures of the hydrophilic domain in several redox states.
Last year was marked by fascinating breakthroughs in the understanding of the
complete structure. We described the architecture of the membrane domain and of
the entire bacterial complex I. X-ray analysis of the larger mitochondrial enzyme
has also been published. The core subunits of the bacterial and mitochondrial
enzymes have remarkably similar structures. The proposed mechanism of coupling
between electron transfer and proton translocation involves long-range conformational
changes, coordinated in part by a long α-helix, akin to the coupling rod of a
steam engine.

text: 'Modern α-proteobacteria are thought to be closely related to the ancient
symbiont of eukaryotes, an ancestor of mitochondria. Respiratory complex I from
α-proteobacteria and mitochondria is well conserved at the level of the 14 "core"
subunits, consistent with that notion. Mitochondrial complex I contains the core
subunits, present in all species, and up to 31 "supernumerary" subunits,
generally thought to have originated only within eukaryotic lineages. However,
the full protein composition of an α-proteobacterial complex I has not been established
previously. Here, we report the first purification and characterization of complex
I from the α-proteobacterium Paracoccus denitrificans. Single particle electron
microscopy shows that the complex has a well defined L-shape. Unexpectedly, in
addition to the 14 core subunits, the enzyme also contains homologues of three
supernumerary mitochondrial subunits as follows: B17.2, AQDQ/18, and 13 kDa (bovine
nomenclature). This finding suggests that evolution of complex I via addition
of supernumerary or "accessory" subunits started before the original
endosymbiotic event that led to the creation of the eukaryotic cell. It also provides
further confirmation that α-proteobacteria are the closest extant relatives of
mitochondria.'

In Escherichia coli, the pole-to-pole oscillation of the Min proteins directs septum formation to midcell, which is required for symmetric cell division. In vitro, protein waves emerge from the self-organization of MinD, a membrane-binding ATPase, and its activator MinE. For wave propagation, the proteins need to cycle through states of collective membrane binding and unbinding. Although MinD presumably undergoes cooperative membrane attachment, it is unclear how synchronous detachment is coordinated. We used confocal and single-molecule microscopy to elucidate the order of events during Min wave propagation. We propose that protein detachment at the rear of the wave, and the formation of the E-ring, are accomplished by two complementary processes: first, local accumulation of MinE due to rapid rebinding, leading to dynamic instability; and second, a structural change induced by membrane-interaction of MinE in an equimolar MinD-MinE (MinDE) complex, which supports the robustness of pattern formation.

text: One of the most fundamental features of biological systems is probably their
ability to self-organize in space and time on different scales. Despite many elaborate
theoretical models of how molecular self-organization can come about, only a few
experimental systems of biological origin have so far been rigorously described,
due mostly to their inherent complexity. The most promising strategy of modern
biophysics is thus to identify minimal biological systems showing self-organized
emergent behavior. One of the best-understood examples of protein self-organization,
which has recently been successfully reconstituted in vitro, is represented by
the oscillations of the Min proteins in Escherichia coli. In this review, we summarize
the current understanding of the mechanism of Min protein self-organization in
vivo and in vitro. We discuss the potential of the Min oscillations to sense the
geometry of the cell and suggest that spontaneous protein waves could be a general
means of intracellular organization. We hypothesize that cooperative membrane
binding and unbinding, e.g., as an energy-dependent switch, may act as an important
regulatory mechanism for protein oscillations and pattern formation in the cell.

text: Many species have morphologically and genetically differentiated sex chromosomes,
such as the XY pair of mammals. Y chromosomes are often highly degenerated and
carry few functional genes, so that XY males have only one copy of most Xlinked
genes (whereas females have two). As a result, chromosome-wide mechanisms of dosage
compensation, such as the mammalian X-inactivation, often evolve to reestablish
expression balance. A similar phenomenon is expected in femaleheterogametic species,
where ZW females should suffer from imbalances due to W-chromosome degeneration.
However, no global dosage compensation mechanisms have been detected in the two
independent ZW systems that have been studied systematically (birds and silkworm),
leading to the suggestion that lack of global dosage compensation may be a general
feature of female-heterogametic species. However, analyses of other independently
evolved ZW systems are required to test if this is the case. In this study, we
use published genomic and expression data to test for the presence of global dosage
compensation in Schistosoma mansoni, a trematode parasite that causes schistosomiasis
in humans. We find that Z-linked expression is reduced relative to autosomal expression
in females but not males, consistent with incomplete or localized dosage compensation.
This gives further support to the theory that female-heterogametic species may
not require global mechanisms of dosage compensation.

text: This chapter presents a method for real-time animation of highly detailed
facial expressions based on sparse motion captures data and a limited set of static
example poses. The method for real-time animation of highly detailed facial expressions
decomposes geometry into large-scale motion and fine-scale details, such as expression
wrinkles. Both large- and fine-scale deformation algorithms run entirely on the
GPU, and our implementation based on CUDA achieves an overall performance of about
30 fps. The face conveys the most relevant visual characteristics of human identity
and expression. Hence, realistic facial animations or interactions with virtual
avatars are important for storytelling and gameplay. However, current approaches
are either computationally expensive, require very specialized capture hardware,
or are extremely labor intensive. At runtime, given an arbitrary facial expression,
the algorithm computes the skin strain from the relative distance between marker
points and derives fine-scale corrections for the largescale deformation. During
gameplay only the sparse set of marker-point positions is transmitted to the GPU.
The face animation is entirely computed on the GPU where the resulting mesh can
directly be used as input for the rendering stages. This data can be easily obtained
by traditional capture hardware. The proposed in-game algorithm is fast. It also
is easy to implement and maps well onto programmable GPUs.

text: We present a new technique for passive and markerless facial performance capture
based on anchor frames. Our method starts with high resolution per-frame geometry
acquisition using state-of-theart stereo reconstruction, and proceeds to establish
a single triangle mesh that is propagated through the entire performance. Leveraging
the fact that facial performances often contain repetitive subsequences, we identify
anchor frames as those which contain similar facial expressions to a manually
chosen reference expression. Anchor frames are automatically computed over one
or even multiple performances. We introduce a robust image-space tracking method
that computes pixel matches directly from the reference frame to all anchor frames,
and thereby to the remaining frames in the sequence via sequential matching. This
allows us to propagate one reconstructed frame to an entire sequence in parallel,
in contrast to previous sequential methods. Our anchored reconstruction approach
also limits tracker drift and robustly handles occlusions and motion blur. The
parallel tracking and mesh propagation offer low computation times. Our technique
will even automatically match anchor frames across different sequences captured
on different occasions, propagating a single mesh to all performances.

text: Acquiring panoramic images using stitching takes a lot of time and moving
objects may cause ghosting. It is also difficult to obtain a full spherical panorama,
because the downward picture cannot be captured while the camera is mounted on
the tripod.

text: Let P be the Ornstein-Uhlenbeck semigroup associated with the stochastic Cauchy
problem dU(t)=AU(t)dt+dWH(t), where A is the generator of a C 0-semigroup S on
a Banach space E, H is a Hilbert subspace of E, and W H is an H-cylindrical Brownian
motion. Assuming that S restricts to a C 0-semigroup on H, we obtain L p -bounds
for D H P(t). We show that if P is analytic, then the invariance assumption is
fulfilled. As an application we determine the L p -domain of the generator of
P explicitly in the case where S restricts to a C 0-semigroup on H which is similar
to an analytic contraction semigroup. The results are applied to the 1D stochastic
heat equation driven by additive space-time white noise.

text: We study, in L1(R̃n; γ) with respect to the gaussian measure, non- tangential
maximal functions and conical square functions associ- ated with the Ornstein-Uhlenbeck
operator by developing a set of techniques which allow us, to some extent, to
compensate for the non-doubling character of the gaussian measure. The main result
asserts that conical square functions can be controlled in L1-norm by non-tangential
maximal functions. Along the way we prove a change of aperture result for the
latter. This complements recent results on gaussian Hardy spaces due to Mauceri
and Meda.

Let K be an irreducible and reversible Markov kernel on a finite set X. We construct a metric W on the set of probability measures on X and show that with respect to this metric, the law of the continuous time Markov chain evolves as the gradient flow of the entropy. This result is a discrete counterpart of the Wasserstein gradient flow interpretation of the heat flow in Rn by Jordan, Kinderlehrer and Otto (1998). The metric W is similar to, but different from, the L2-Wasserstein metric, and is defined via a discrete variant of the Benamou–Brenier formula.

text: A (diatomic) shape resonance is a metastable state of a pair of colliding
atoms quasi-bound by the centrifugal barrier imposed by the angular momentum involved
in the collision. The temporary trapping of the atoms' scattering wavefunction
corresponds to an enhanced atom pair density at low interatomic separations. This
leads to larger overlap of the wavefunctions involved in a molecule formation
process such as photoassociation, rendering the process more efficient. However,
for an ensemble of atoms, the atom pair density will only be enhanced if the energy
of the resonance comes close to the temperature of the atomic ensemble. Herein
we explore the possibility of controlling the energy of a shape resonance by shifting
it toward the temperature of atoms confined in a trap. The shifts are imparted
by the interaction of non-resonant light with the anisotropic polarizability of
the atom pair, which affects both the centrifugal barrier and the pair's rotational
and vibrational levels. We find that at laser intensities of up to 5×109 W/cm2
the pair density is increased by one order of magnitude for 87Rb atoms at 100μK
and by two orders of magnitude for 88Sr atoms at 20μK.

text: We show that dressing polar molecules with a far-off-resonant optical field
leads to new types of intermolecular potentials, which undergo a crossover from
the inverse power to oscillating behavior depending on the intermolecular distance,
and whose parameters can be tuned by varying the laser intensity and wavelength.
We present analytic expressions for the potential energy surfaces, thereby providing
direct access to the parameters of an optical field required to design intermolecular
interactions experimentally.
