text: Two of the most fundamental prototypes of greedy optimization are the matching
pursuit and Frank-Wolfe algorithms. In this paper, we take a unified view on both
classes of methods, leading to the first explicit convergence rates of matching
pursuit methods in an optimization sense, for general sets of atoms. We derive
sublinear (1/t) convergence for both classes on general smooth objectives, and
linear convergence on strongly convex objectives, as well as a clear correspondence
of algorithm variants. Our presented algorithms and rates are affine invariant,
and do not need any incoherence or sparsity assumptions.

text: Greedy optimization methods such as Matching Pursuit (MP) and Frank-Wolfe
(FW) algorithms regained popularity in recent years due to their simplicity, effectiveness
and theoretical guarantees. MP and FW address optimization over the linear span
and the convex hull of a set of atoms, respectively. In this paper, we consider
the intermediate case of optimization over the convex cone, parametrized as the
conic hull of a generic atom set, leading to the first principled definitions
of non-negative MP algorithms for which we give explicit convergence rates and
demonstrate excellent empirical performance. In particular, we derive sublinear
(O(1/t)) convergence on general smooth and convex objectives, and linear convergence
(O(e−t)) on strongly convex objectives, in both cases for general sets of atoms.
Furthermore, we establish a clear correspondence of our algorithms to known algorithms
from the MP and FW literature. Our novel algorithms and analyses target general
atom sets and general objective functions, and hence are directly applicable to
a large variety of learning settings.

text: 'The bacteriophage M13 has found frequent applications in nanobiotechnology
due to its chemically and genetically tunable protein surface and its ability
to self-assemble into colloidal membranes. Additionally, its single-stranded (ss)
genome is commonly used as scaffold for DNA origami. Despite the manifold uses
of M13, upstream production methods for phage and scaffold ssDNA are underexamined
with respect to future industrial usage. Here, the high-cell-density phage production
with Escherichia coli as host organism was studied in respect of medium composition,
infection time, multiplicity of infection, and specific growth rate. The specific
growth rate and the multiplicity of infection were identified as the crucial state
variables that influence phage amplification rate on one hand and the concentration
of produced ssDNA on the other hand. Using a growth rate of 0.15 h−1 and a multiplicity
of infection of 0.05 pfu cfu−1 in the fed-batch production process, the concentration
of pure isolated M13 ssDNA usable for scaffolded DNA origami could be enhanced
by 54% to 590 mg L−1. Thus, our results help enabling M13 production for industrial
uses in nanobiotechnology. Biotechnol. Bioeng. 2017;114: 777–784.'

text: We describe an approach to bottom-up fabrication that allows integration of
the functional diversity of proteins into designed three-dimensional structural
frameworks. A set of custom staple proteins based on transcription activator–like
effector proteins folds a double-stranded DNA template into a user-defined shape.
Each staple protein is designed to recognize and closely link two distinct double-helical
DNA sequences at separate positions on the template. We present design rules for
constructing megadalton-scale DNA-protein hybrid shapes; introduce various structural
motifs, such as custom curvature, corners, and vertices; and describe principles
for creating multilayer DNA-protein objects with enhanced rigidity. We demonstrate
self-assembly of our hybrid nanostructures in one-pot mixtures that include the
genetic information for the designed proteins, the template DNA, RNA polymerase,
ribosomes, and cofactors for transcription and translation.

text: DNA nanotechnology, in particular DNA origami, enables the bottom-up self-assembly
of micrometre-scale, three-dimensional structures with nanometre-precise features1,2,3,4,5,6,7,8,9,10,11,12.
These structures are customizable in that they can be site-specifically functionalized13
or constructed to exhibit machine-like14,15 or logic-gating behaviour16. Their
use has been limited to applications that require only small amounts of material
(of the order of micrograms), owing to the limitations of current production methods.
But many proposed applications, for example as therapeutic agents or in complex
materials3,16,17,18,19,20,21,22, could be realized if more material could be used.
In DNA origami, a nanostructure is assembled from a very long single-stranded
scaffold molecule held in place by many short single-stranded staple oligonucleotides.
Only the bacteriophage-derived scaffold molecules are amenable to scalable and
efficient mass production23; the shorter staple strands are obtained through costly
solid-phase synthesis24 or enzymatic processes25. Here we show that single strands
of DNA of virtually arbitrary length and with virtually arbitrary sequences can
be produced in a scalable and cost-efficient manner by using bacteriophages to
generate single-stranded precursor DNA that contains target strand sequences interleaved
with self-excising ‘cassettes’, with each cassette comprising two Zn2+-dependent
DNA-cleaving DNA enzymes. We produce all of the necessary single strands of DNA
for several DNA origami using shaker-flask cultures, and demonstrate end-to-end
production of macroscopic amounts of a DNA origami nanorod in a litre-scale stirred-tank
bioreactor. Our method is compatible with existing DNA origami design frameworks
and retains the modularity and addressability of DNA origami objects that are
necessary for implementing custom modifications using functional groups. With
all of the production and purification steps amenable to scaling, we expect that
our method will expand the scope of DNA nanotechnology in many areas of science
and technology.

text: Here we describe an approach to bottom-up fabrication with nanometer-precision
that allows integrating the functional diversity of proteins in designed three-dimensional
structural frameworks. We reimagined the successful DNA origami design principle
using a set of custom staple proteins to fold a double-stranded DNA template into
a user-defined shape. Each staple protein recognizes two distinct double-helical
DNA sequences and can carry additional functionalities. The staple proteins we
present here are based on the transcription activator-like (TAL) effector proteins.
Due to their repetitive structure these proteins offer a unique programmability
that enables us to construct numerous staple proteins targeting any desired DNA
sequence. Our approach is general, meaning that many different objects may be
created using the same set of rules, and it is modular, because components can
be modified or exchanged individually. We present rules for constructing megadalton-scale
DNA-protein hybrid nanostructures; introduce important structural motifs, such
as curvature, corners, and vertices; describe principles for creating multi-layer
DNA-protein objects with enhanced rigidity; and demonstrate the possibility to
combine our DNA-protein hybrid origami with conventional DNA nanotechnology. Since
all components can be encoded genetically, our structures should be amenable to
biotechnological mass-production. Moreover, since the target objects can self-assemble
at room temperature in near-physiological buffer, our hybrid origami may also
provide an attractive method to realize positioning and scaffolding tasks in vivo.
We expect our method to find application both in scaffolding protein functionalities
and in manipulating the spatial arrangement of genomic DNA.

text: Establishing precise control over the shape and the interactions of the microscopic
building blocks is essential for design of macroscopic soft materials with novel
structural, optical and mechanical properties. Here, we demonstrate robust assembly
of DNA origami filaments into cholesteric liquid crystals, one-dimensional supramolecular
twisted ribbons and two-dimensional colloidal membranes. The exquisite control
afforded by the DNA origami technology establishes a quantitative relationship
between the microscopic filament structure and the macroscopic cholesteric pitch.
Furthermore, it also enables robust assembly of one-dimensional twisted ribbons,
which behave as effective supramolecular polymers whose structure and elastic
properties can be precisely tuned by controlling the geometry of the elemental
building blocks. Our results demonstrate the potential synergy between DNA origami
technology and colloidal science, in which the former allows for rapid and robust
synthesis of complex particles, and the latter can be used to assemble such particles
into bulk materials.

text: Magnetic anisotropy in strontium iridate (Sr2IrO4) is found to be large because
of the strong spin-orbit interactions. In our work, we studied the in-plane magnetic
anisotropy of Sr2IrO4 and traced the anisotropic exchange interactions between
the isospins in the crystal. The magnetic-field-dependent torque τ(H) showed a
prominent transition from the canted antiferromagnetic state to the weak ferromagnetic
(WFM) state. A comprehensive analysis was conducted to examine the isotropic and
anisotropic regimes and probe the easy magnetization axis along the a b plane.
The angle-dependent torque τ(θ) revealed a deviation from the sinusoidal behavior,
and small differences in hysteresis were observed around 0° and 90° in the low-magnetic-field
regime. This indicates that the orientation of the easy axis of the FM component
is along the b axis, where the antiferromagnetic to WFM spin-flop transition occurs.
We compared the coefficients of the magnetic susceptibility tensors and captured
the anisotropy of the material. The in-plane τ(θ) revealed a tendency toward isotropic
behavior for fields with values above the field value of the WFM transition.

text: We study the lengths of curves passing through a fixed number of points on
the boundary of a convex shape in the plane. We show that, for any convex shape
K, there exist four points on the boundary of K such that the length of any curve
passing through these points is at least half of the perimeter of K. It is also
shown that the same statement does not remain valid with the additional constraint
that the points are extreme points of K. Moreover, the factor ½ cannot
be achieved with any fixed number of extreme points. We conclude the paper with
a few other inequalities related to the perimeter of a convex shape.

text: "Frequency-independent selection is generally considered as a force that acts
to reduce the genetic variation in evolving populations, yet rigorous arguments
for this idea are scarce. When selection fluctuates in time, it is unclear whether
frequency-independent selection may maintain genetic polymorphism without invoking
additional mechanisms. We show that constant frequency-independent selection with
arbitrary epistasis on a well-mixed haploid population eliminates genetic variation
if we assume linkage equilibrium between alleles. To this end, we introduce the
notion of frequency-independent selection at the level of alleles, which is sufficient
to prove our claim and contains the notion of frequency-independent selection
on haploids. When selection and recombination are weak but of the same order,
there may be strong linkage disequilibrium; numerical calculations show that stable
equilibria are highly unlikely. Using the example of a diallelic two-locus model,
we then demonstrate that frequency-independent selection that fluctuates in time
can maintain stable polymorphism if linkage disequilibrium changes its sign periodically.
We put our findings in the context of results from the existing literature and
point out those scenarios in which the possible role of frequency-independent
selection in maintaining genetic variation remains unclear.\r\n"

text: We develop a probabilistic technique for colorizing grayscale natural images.
In light of the intrinsic uncertainty of this task, the proposed probabilistic
framework has numerous desirable properties. In particular, our model is able
to produce multiple plausible and vivid colorizations for a given grayscale image
and is one of the first colorization models to provide a proper stochastic sampling
scheme. Moreover, our training procedure is supported by a rigorous theoretical
framework that does not require any ad hoc heuristics and allows for efficient
modeling and learning of the joint pixel color distribution.We demonstrate strong
quantitative and qualitative experimental results on the CIFAR-10 dataset and
the challenging ILSVRC 2012 dataset.

text: Pools of air cooled by partial rain evaporation span up to several hundreds
of kilometers in nature and typically last less than 1 day, ultimately losing
their identity to the large-scale flow. These fundamentally differ in character
from the radiatively-driven dry pools defining convective aggregation. Advancement
in remote sensing and in computer capabilities has promoted exploration of how
precipitation-induced cold pool processes modify the convective spectrum and life
cycle. This contribution surveys current understanding of such cold pools over
the tropical and subtropical oceans. In shallow convection with low rain rates,
the cold pools moisten, preserving the near-surface equivalent potential temperature
or increasing it if the surface moisture fluxes cannot ventilate beyond the new
surface layer; both conditions indicate downdraft origin air from within the boundary
layer. When rain rates exceed ∼ 2 mm h−1, convective-scale downdrafts can bring
down drier air of lower equivalent potential temperature from above the boundary
layer. The resulting density currents facilitate the lifting of locally thermodynamically
favorable air and can impose an arc-shaped mesoscale cloud organization. This
organization allows clouds capable of reaching 4–5 km within otherwise dry environments.
These are more commonly observed in the northern hemisphere trade wind regime,
where the flow to the intertropical convergence zone is unimpeded by the equator.
Their near-surface air properties share much with those shown from cold pools
sampled in the equatorial Indian Ocean. Cold pools are most effective at influencing
the mesoscale organization when the atmosphere is moist in the lower free troposphere
and dry above, suggesting an optimal range of water vapor paths. Outstanding questions
on the relationship between cold pools, their accompanying moisture distribution
and cloud cover are detailed further. Near-surface water vapor rings are documented
in one model inside but near the cold pool edge; these are not consistent with
observations, but do improve with smaller horizontal grid spacings.

text: Convective self-aggregation, the spontaneous organization of initially scattered
convection into isolated convective clusters despite spatially homogeneous boundary
conditions and forcing, was first recognized and studied in idealized numerical
simulations. While there is a rich history of observational work on convective
clustering and organization, there have been only a few studies that have analyzed
observations to look specifically for processes related to self-aggregation in
models. Here we review observational work in both of these categories and motivate
the need for more of this work. We acknowledge that self-aggregation may appear
to be far-removed from observed convective organization in terms of time scales,
initial conditions, initiation processes, and mean state extremes, but we argue
that these differences vary greatly across the diverse range of model simulations
in the literature and that these comparisons are already offering important insights
into real tropical phenomena. Some preliminary new findings are presented, including
results showing that a self-aggregation simulation with square geometry has too
broad distribution of humidity and is too dry in the driest regions when compared
with radiosonde records from Nauru, while an elongated channel simulation has
realistic representations of atmospheric humidity and its variability. We discuss
recent work increasing our understanding of how organized convection and climate
change may interact, and how model discrepancies related to this question are
prompting interest in observational comparisons. We also propose possible future
directions for observational work related to convective aggregation, including
novel satellite approaches and a ground-based observational network.

text: Organized convection in the tropics occurs across a range of spatial and temporal
scales and strongly influences cloud cover and humidity. One mode of organization
found is “self-aggregation,” in which moist convection spontaneously organizes
into one or several isolated clusters despite spatially homogeneous boundary conditions
and forcing. Self-aggregation is driven by interactions between clouds, moisture,
radiation, surface fluxes, and circulation, and occurs in a wide variety of idealized
simulations of radiative–convective equilibrium. Here we provide a review of convective
self-aggregation in numerical simulations, including its character, causes, and
effects. We describe the evolution of self-aggregation including its time and
length scales and the physical mechanisms leading to its triggering and maintenance,
and we also discuss possible links to climate and climate change.

text: Infections with potentially lethal pathogens may negatively affect an individual’s
lifespan and decrease its reproductive value. The terminal investment hypothesis
predicts that individuals faced with a reduced survival should invest more into
reproduction instead of maintenance and growth. Several studies suggest that individuals
are indeed able to estimate their body condition and to increase their reproductive
effort with approaching death, while other studies gave ambiguous results. We
investigate whether queens of a perennial social insect (ant) are able to boost
their reproduction following infection with an obligate killing pathogen. Social
insect queens are special with regard to reproduction and aging, as they outlive
conspecific non-reproductive workers. Moreover, in the ant Cardiocondyla obscurior,
fecundity increases with queen age. However, it remained unclear whether this
reflects negative reproductive senescence or terminal investment in response to
approaching death. Here, we test whether queens of C. obscurior react to infection
with the entomopathogenic fungus Metarhizium brunneum by an increased egg-laying
rate. We show that a fungal infection triggers a reinforced investment in reproduction
in queens. This adjustment of the reproductive rate by ant queens is consistent
with predictions of the terminal investment hypothesis and is reported for the
first time in a social insect.

text: We propose a dual decomposition and linear program relaxation of the NP-hard
minimum cost multicut problem. Unlike other polyhedral relaxations of the multicut
polytope, it is amenable to efficient optimization by message passing. Like other
polyhedral relaxations, it can be tightened efficiently by cutting planes. We
define an algorithm that alternates between message passing and efficient separation
of cycle- and odd-wheel inequalities. This algorithm is more efficient than state-of-the-art
algorithms based on linear programming, including algorithms written in the framework
of leading commercial software, as we show in experiments with large instances
of the problem from applications in computer vision, biomedical image analysis
and data mining.

text: Previous numerical studies of the dissipation of internal tides in idealized
settings suggest the existence of a critical latitude (~29°) where dissipation
is enhanced. But observations only indicate a modest enhancement at this latitude.
To resolve this difference between observational and numerical results, the authors
study the latitudinal dependence of internal tides’ dissipation in more realistic
conditions. In particular, the ocean is not a quiescent medium; the presence of
large-scale currents or mesoscale eddies can impact the propagation and dissipation
of internal tides. This paper investigates the impact of a weak background mean
current in numerical simulations. The authors focus on the local dissipation of
high spatial mode internal waves near their generation site. The vertical profile
of dissipation and its variation with latitude without the mean current are consistent
with earlier studies. But adding a weak mean current has a major impact on the
latitudinal distribution of dissipation. The peak at the critical latitude disappears,
and the dissipation is closer to a constant, albeit with two weak peaks at ~25°
and ~35° latitude. This disappearance results from the Doppler shift of the internal
tides’ frequency, which hinders the nonlinear transfer of energy to small-scale
secondary waves via the parametric subharmonic instability (PSI). The new two
weak peaks correspond to the Doppler-shifted critical latitudes of the left- and
right-propagating waves. The results are confirmed in simulations with simple
sinusoidal topography. Thus, although nonlinear transfers via PSI are efficient
at dissipating internal tides, the exact location of the dissipation is sensitive
to large-scale oceanic conditions.

text: We study the quadratic assignment problem, in computer vision also known as
graph matching. Two leading solvers for this problem optimize the Lagrange decomposition
duals with sub-gradient and dual ascent (also known as message passing) updates.
We explore this direction further and propose several additional Lagrangean relaxations
of the graph matching problem along with corresponding algorithms, which are all
based on a common dual ascent framework. Our extensive empirical evaluation gives
several theoretical insights and suggests a new state-of-the-art anytime solver
for the considered problem. Our improvement over state-of-the-art is particularly
visible on a new dataset with large-scale sparse problem instances containing
more than 500 graph nodes each.

text: Advances in colloidal synthesis allow for the design of particles with controlled
patches. This article reviews routes towards colloidal locomotion, where energy
is consumed and converted into motion, and its implementation with active patchy
particles. A special emphasis is given to phoretic swimmers, where the self-propulsion
originates from an interfacial phenomenon, raising experimental challenges and
opening up opportunities for particles with controlled anisotropic surface chemistry
and novel behaviors.
