text: In this Letter, we investigate experimentally the nonequilibrium steady state
of an active colloidal suspension under gravity field. The active particles are
made of chemically powered colloids, showing self propulsion in the presence of
an added fuel, here hydrogen peroxide. The active suspension is studied in a dedicated
microfluidic device, made of permeable gel microstructures. Both the microdynamics
of individual colloids and the global stationary state of the suspension under
gravity are measured with optical microscopy. This yields a direct measurement
of the effective temperature of the active system as a function of the particle
activity, on the basis of the fluctuation-dissipation relationship. Our work is
a first step in the experimental exploration of the out-of-equilibrium properties
of active colloidal systems.

text: "We have found a new way to express the solutions of the RSM (Reynolds Stress
Model) equations that allows us to present the turbulent diffusivities for heat,
salt and momentum in a way that is considerably simpler and thus easier to implement
than in previous work. The RSM provides the dimensionless mixing efficiencies
Γα (α stands for heat, salt and momentum). However, to compute the diffusivities,
one needs additional information, specifically, the dissipation ε. Since a dynamic
equation for the latter that includes the physical processes relevant to the ocean
is still not available, one must resort to different sources of information outside
the RSM to obtain a complete Mixing Scheme usable in OGCMs.\r\nAs for the RSM
results, we show that the Γα’s are functions of both Ri and Rρ (Richardson number
and density ratio representing double diffusion, DD); the Γα are different for
heat, salt and momentum; in the case of heat, the traditional value Γh = 0.2 is
valid only in the presence of strong shear (when DD is inoperative) while when
shear subsides, NATRE data show that Γh can be three times as large, a result
that we reproduce. The salt Γs is given in terms of Γh. The momentum Γm has thus
far been guessed with different prescriptions while the RSM provides a well defined
expression for Γm(Ri, Rρ). Having tested Γh, we then test the momentum Γm by showing
that the turbulent Prandtl number Γm/Γh vs. Ri reproduces the available data quite
well.\r\n\r\nAs for the dissipation ε, we use different representations, one for
the mixed layer (ML), one for the thermocline and one for the ocean’s bottom.
For the ML, we adopt a procedure analogous to the one successfully used in PB
(planetary boundary layer) studies; for the thermocline, we employ an expression
for the variable εN−2 from studies of the internal gravity waves spectra which
includes a latitude dependence; for the ocean bottom, we adopt the enhanced bottom
diffusivity expression used by previous authors but with a state of the art internal
tidal energy formulation and replace the fixed Γα = 0.2 with the RSM result that
brings into the problem the Ri, Rρ dependence of the Γα; the unresolved bottom
drag, which has thus far been either ignored or modeled with heuristic relations,
is modeled using a formalism we previously developed and tested in PBL studies.\r\nWe
carried out several tests without an OGCM. Prandtl and flux Richardson numbers
vs. Ri. The RSM model reproduces both types of data satisfactorily. DD and Mixing
efficiency Γh(Ri, Rρ). The RSM model reproduces well the NATRE data. Bimodal ε-distribution.
NATRE data show that ε(Ri < 1) ≈ 10ε(Ri > 1), which our model reproduces. Heat
to salt flux ratio. In the Ri ≫ 1 regime, the RSM predictions reproduce the data
satisfactorily. NATRE mass diffusivity. The z-profile of the mass diffusivity
reproduces well the measurements at NATRE. The local form of the mixing scheme
is algebraic with one cubic equation to solve."

text: "The factors governing the rate of change in the amount of atmospheric water
vapor are analyzed in simulations of climate change. The global-mean amount of
water vapor is estimated to increase at a differential rate of 7.3% K − 1 with
respect to global-mean surface air temperature in the multi-model mean. Larger
rates of change result if the fractional change is evaluated over a finite change
in temperature (e.g., 8.2% K − 1 for a 3 K warming), and rates of change of zonal-mean
column water vapor range from 6 to 12% K − 1 depending on latitude.\r\nClausius–Clapeyron
scaling is directly evaluated using an invariant distribution of monthly-mean
relative humidity, giving a rate of 7.4% K − 1 for global-mean water vapor. There
are deviations from Clausius–Clapeyron scaling of zonal-mean column water vapor
in the tropics and mid-latitudes, but they largely cancel in the global mean.
A purely thermodynamic scaling based on a saturated troposphere gives a higher
global rate of 7.9% K − 1.\r\nSurface specific humidity increases at a rate of
5.7% K − 1, considerably lower than the rate for global-mean water vapor. Surface
specific humidity closely follows Clausius–Clapeyron scaling over ocean. But there
are widespread decreases in surface relative humidity over land (by more than
1% K − 1 in many regions), and it is argued that decreases of this magnitude could
result from the land/ocean contrast in surface warming."

text: Most eukaryotic cells sense and respond to the mechanical properties of their
surroundings. This can strongly influence their collective behavior in embryonic
development, tissue function, and wound healing. We use a deformable substrate
to measure collective behavior in cell motion due to substrate mediated cell-cell
interactions. We quantify spatial and temporal correlations in migration velocity
and substrate deformation, and show that cooperative cell-driven patterns of substrate
deformation mediate long-distance mechanical coupling between cells and control
collective cell migration.

text: Eukaryotic cytosine methylation represses transcription but also occurs in
the bodies of active genes, and the extent of methylation biology conservation
is unclear. We quantified DNA methylation in 17 eukaryotic genomes and found that
gene body methylation is conserved between plants and animals, whereas selective
methylation of transposons is not. We show that methylation of plant transposons
in the CHG context extends to green algae and that exclusion of histone H2A.Z
from methylated DNA is conserved between plants and animals, and we present evidence
for RNA-directed DNA methylation of fungal genes. Our data demonstrate that extant
DNA methylation systems are mosaics of conserved and derived features, and indicate
that gene body methylation is an ancient property of eukaryotic genomes.

text: 'Cytosine methylation silences transposable elements in plants, vertebrates,
and fungi but also regulates gene expression. Plant methylation is catalyzed by
three families of enzymes, each with a preferred sequence context: CG, CHG (H
= A, C, or T), and CHH, with CHH methylation targeted by the RNAi pathway. Arabidopsis
thaliana endosperm, a placenta-like tissue that nourishes the embryo, is globally
hypomethylated in the CG context while retaining high non-CG methylation. Global
methylation dynamics in seeds of cereal crops that provide the bulk of human nutrition
remain unknown. Here, we show that rice endosperm DNA is hypomethylated in all
sequence contexts. Non-CG methylation is reduced evenly across the genome, whereas
CG hypomethylation is localized. CHH methylation of small transposable elements
is increased in embryos, suggesting that endosperm demethylation enhances transposon
silencing. Genes preferentially expressed in endosperm, including those coding
for major storage proteins and starch synthesizing enzymes, are frequently hypomethylated
in endosperm, indicating that DNA methylation is a crucial regulator of rice endosperm
biogenesis. Our data show that genome-wide reshaping of seed DNA methylation is
conserved among angiosperms and has a profound effect on gene expression in cereal
crops.'

text: We use numerical simulations to show how noninteracting hard particles binding
to a deformable elastic shell may self-assemble into a variety of linear patterns.
This is a result of the nontrivial elastic response to deformations of shells.
The morphology of the patterns can be controlled by the mechanical properties
of the surface, and can be fine-tuned by varying the binding energy of the particles.
We also repeat our calculations for a fully flexible chain and find that the chain
conformations follow patterns similar to those formed by the nanoparticles under
analogous conditions. We propose a simple way of understanding and sorting the
different structures and relate it to the underlying shape transition of the shell.
Finally, we discuss the implications of our results.

text: 'An extensive computational study of the conformational preferences of three
capped dipeptides: Ac-Xxx-Phe-NH2, Xxx = Gly, Ala, Val is reported. On the basis
of local second-order Møller–Plesset perturbation theory (LMP2) and DFT computations
we were able to identify the experimentally observed conformers as γL–γL(g−) and
β-turn I(g+) in Ac-Gly-Phe-NH2, and Ac-Ala-Phe-NH2, and as the closely related
γL(g+)–γL(g−) and β-turn I(a,g+) in Ac-Val-Phe-NH2. In contrast to the experimental
observation that peptides with bulky side chain have a propensity for β-turns,
we show that in Ac-Val-Phe-NH2 the minimum energy structure corresponds to the
experimentally non detected β-strand.'

text: 'We use numerical simulations to study the phase behavior of a system of purely
repulsive soft dumbbells as a function of size ratio of the two components and
their relative degree of deformability. We find a plethora of different phases,
which includes most of the mesophases observed in self-assembly of block copolymers
but also crystalline structures formed by asymmetric, hard binary mixtures. Our
results detail the phenomenological behavior of these systems when softness is
introduced in terms of two different classes of interparticle interactions: (a)
the elastic Hertz potential, which has a finite energy cost for complete overlap
of any two components, and (b) a generic power-law repulsion with tunable exponent.
We discuss how simple geometric arguments can be used to account for the large
structural variety observed in these systems and detail the similarities and differences
in the phase behavior for the two classes of potentials under consideration.'

text: We use numerical simulations to show how a fully flexible filament binding
to a deformable cylindrical surface may acquire a macroscopic persistence length
and a helical conformation. This is a result of the nontrivial elastic response
to deformations of elastic sheets. We find that the filament’s helical pitch is
completely determined by the mechanical properties of the surface, and can be
easily tuned by varying the surface stretching rigidity. We propose simple scaling
arguments to understand the physical mechanism behind this phenomenon and present
a phase diagram indicating under what conditions one should expect a fully flexible
chain to behave as a helical semiflexible filament. Finally, we discuss the implications
of our results.

text: Recent years have seen tremendous progress in the field of cold and ultracold
molecules. A central goal in the field is currently the realization of stable
rovibronic ground-state molecular samples in the regime of quantum degeneracy,
e.g. in the form of molecular Bose-Einstein condensates, molecular degenerate
Fermi gases, or, when an optical lattice is present, molecular Mott-insulator
phases. However, molecular samples are not readily cooled to the extremely low
temperatures at which quantum degeneracy occurs. In particular, laser cooling,
the \'workhorse\' for the field of atomic quantum gases, is generally not applicable
to molecular samples. Here we take an important step beyond previous work1 and
provide details on the realization of an ultracold quantum gas of ground-state
dimer molecules trapped in an optical lattice as recently reported in Ref. 2.
We demonstrate full control over all internal and external quantum degrees of
freedom for the ground-state molecules by deterministically preparing the molecules
in a single quantum state, i.e. in a specific hyperfine sublevel of the rovibronic
ground state, while the molecules are trapped in the motional ground state of
the individual lattice wells. We circumvent the problem of cooling by associating
weakly-bound molecules out of a zero-temperature atomic Mott-insulator state and
by transferring these to the absolute ground state in a four-photon STIRAP process.
Our preparation procedure directly leads to a long-lived, lattice-trapped molecular
many-body state, which we expect to form the platform for many of the envisioned
future experiments with molecular quantum gases, e.g. on precision molecular spectroscopy,
quantum information science, and dipolar quantum systems.

text: Control over all internal and external degrees of freedom of molecules at
the level of single quantum states will enable a series of fundamental studies
in physics and chemistry1,2. In particular, samples of ground-state molecules
at ultralow temperatures and high number densities will facilitate new quantum-gas
studies3 and future applications in quantum information science4. However, high
phase-space densities for molecular samples are not readily attainable because
efficient cooling techniques such as laser cooling are lacking. Here we produce
an ultracold and dense sample of molecules in a single hyperfine level of the
rovibronic ground state with each molecule individually trapped in the motional
ground state of an optical lattice well. Starting from a zero-temperature atomic
Mott-insulator state with optimized double-site occupancy6, weakly bound dimer
molecules are efficiently associated on a Feshbach resonance7 and subsequently
transferred to the rovibronic ground state by a stimulated four-photon process
with >50% efficiency. The molecules are trapped in the lattice and have a lifetime
of 8 s. Our results present a crucial step towards Bose-Einstein condensation
of ground-state molecules and, when suitably generalized to polar heteronuclear
molecules, the realization of dipolar quantum-gas phases in optical lattices8-10.

text: We report on the observation of confinement-induced resonances in strongly
interacting quantum-gas systems with tunable interactions for one- and two-dimensional
geometry. Atom-atom scattering is substantially modified when the s-wave scattering
length approaches the length scale associated with the tight transversal confinement,
leading to characteristic loss and heating signatures. Upon introducing an anisotropy
for the transversal confinement we observe a splitting of the confinement-induced
resonance. With increasing anisotropy additional resonances appear. In the limit
of a two-dimensional system we find that one resonance persists.

text: The phenomenon of matter-wave interference lies at the heart of quantum physics.
It has been observed in various contexts in the limit of non-interacting particles
as a single-particle effect. Here we observe and control matter-wave interference
whose evolution is driven by interparticle interactions. In a multi-path matter-wave
interferometer, the macroscopic manybody wave function of an interacting atomic
Bose-Einstein condensate develops a regular interference pattern, allowing us
to detect and directly visualize the effect of interaction-induced phase shifts.
We demonstrate control over the phase evolution by inhibiting interaction-induced
dephasing and by refocusing a dephased macroscopic matter wave in a spin-echo-type
experiment. Our results show that interactions in a many-body system lead to a
surprisingly coherent evolution, possibly enabling narrow-band and high-brightness
matterwave interferometers based on atom lasers.

text: Particles in a perfect lattice potential perform Bloch oscillations when subject
to a constant force, leading to localization and preventing conductivity. For
a weakly interacting Bose-Einstein condensate of Cs atoms, we observe giant center-of-mass
oscillations in position space with a displacement across hundreds of lattice
sites when we add a periodic modulation to the force near the Bloch frequency.
We study the dependence of these "super" Bloch oscillations on lattice
depth, modulation amplitude, and modulation frequency and show that they provide
a means to induce linear transport in a dissipation-free lattice.

text: Quantum many-body systems can have phase transitions even at zero temperature;
fluctuations arising from Heisenbergĝ€™s uncertainty principle, as opposed to
thermal effects, drive the system from one phase to another. Typically, during
the transition the relative strength of two competing terms in the systemĝ€™s
Hamiltonian changes across a finite critical value. A well-known example is the
Mottĝ€" Hubbard quantum phase transition from a superfluid to an insulating
phase, which has been observed for weakly interacting bosonic atomic gases. However,
for strongly interacting quantum systems confined to lower-dimensional geometry,
a novel type of quantum phase transition may be induced and driven by an arbitrarily
weak perturbation to the Hamiltonian. Here we observe such an effectĝ€"the
sineĝ€"Gordon quantum phase transition from a superfluid Luttinger liquid
to a Mott insulatorĝ€ "in a one-dimensional quantum gas of bosonic caesium
atoms with tunable interactions. For sufficiently strong interactions, the transition
is induced by adding an arbitrarily weak optical lattice commensurate with the
atomic granularity, which leads to immediate pinning of the atoms. We map out
the phase diagram and find that our measurements in the strongly interacting regime
agree well with a quantum field description based on the exactly solvable sineĝ€"Gordon
model. We trace the phase boundary all the way to the weakly interacting regime,
where we find good agreement with the predictions of the one-dimensional Boseĝ€"Hubbard
model. Our results open up the experimental study of quantum phase transitions,
criticality and transport phenomena beyond Hubbard-type models in the context
of ultracold gases.

text: "Inspired by online ad allocation, we study online stochastic packing integer
programs from theoretical and practical standpoints. We first present a near-optimal
online algorithm for a general class of packing integer programs which model various
online resource allocation problems including online variants of routing, ad allocations,
generalized assignment, and combinatorial auctions. As our main theoretical result,
we prove that a simple dual training-based algorithm achieves a (1 − o(1))-approximation
guarantee in the random order stochastic model. This is a significant improvement
over logarithmic or constant-factor approximations for the adversarial variants
of the same problems (e.g. factor 1−1\U0001D452 for online ad allocation, and
log(m) for online routing). We then focus on the online display ad allocation
problem and study the efficiency and fairness of various training-based and online
allocation algorithms on data sets collected from real-life display ad allocation
system. Our experimental evaluation confirms the effectiveness of training-based
algorithms on real data sets, and also indicates an intrinsic trade-off between
fairness and efficiency."

text: Starting with two models fifty years ago, the discrete marriage game [1] and
the continuous assignment game [2], the study of stable matchings has evolved
into a rich theory with applications in many areas. Most notably, it has lead
to a number of truthful mechanisms that have seen a recent rejuvenation in the
context of sponsored search. In this paper we survey the history of these problems
and provide several links to ongoing research in the field.

text: Two-sided matching markets play a prominent role in economic theory. A prime
example of such a market is the sponsored search market where $n$ advertisers
compete for the assignment of one of $k$ sponsored search results, also known
as ``slots'', for certain keywords they are interested in. Here, as in other markets
of that kind, market equilibria correspond to stable matchings. In this paper,
we show how to modify Kuhn's Hungarian Method (Kuhn, 1955) so that it finds an
optimal stable matching between advertisers and advertising slots in settings
with generalized linear utilities, per-bidder-item reserve prices, and per-bidder-item
maximum prices. The only algorithm for this problem presented so far (Aggarwal
et al., 2009) requires the market to be in ''general position''. We do not make
this assumption.
