text: Most massive stars, the progenitors of core-collapse supernovae, are in close
binary systems and may interact with their companion through mass transfer or
merging. We undertake a population synthesis study to compute the delay-time distribution
of core-collapse supernovae, that is, the supernova rate versus time following
a starburst, taking into account binary interactions. We test the systematic robustness
of our results by running various simulations to account for the uncertainties
in our standard assumptions. We find that a significant fraction, 15+9-8%, of
core-collapse supernovae are “late”, that is, they occur 50–200 Myr after birth,
when all massive single stars have already exploded. These late events originate
predominantly from binary systems with at least one, or, in most cases, with both
stars initially being of intermediate mass (4–8 M⊙). The main evolutionary channels
that contribute often involve either the merging of the initially more massive
primary star with its companion or the engulfment of the remaining core of the
primary by the expanding secondary that has accreted mass at an earlier evolutionary
stage. Also, the total number of core-collapse supernovae increases by 14+15-14%
because of binarity for the same initial stellar mass. The high rate implies that
we should have already observed such late core-collapse supernovae, but have not
recognized them as such. We argue that φ Persei is a likely progenitor and that
eccentric neutron star – white dwarf systems are likely descendants. Late events
can help explain the discrepancy in the delay-time distributions derived from
supernova remnants in the Magellanic Clouds and extragalactic type Ia events,
lowering the contribution of prompt Ia events. We discuss ways to test these predictions
and speculate on the implications for supernova feedback in simulations of galaxy
evolution.

text: The behaviour of gene regulatory networks (GRNs) is typically analysed using
simulation-based statistical testing-like methods. In this paper, we demonstrate
that we can replace this approach by a formal verification-like method that gives
higher assurance and scalability. We focus on Wagner’s weighted GRN model with
varying weights, which is used in evolutionary biology. In the model, weight parameters
represent the gene interaction strength that may change due to genetic mutations.
For a property of interest, we synthesise the constraints over the parameter space
that represent the set of GRNs satisfying the property. We experimentally show
that our parameter synthesis procedure computes the mutational robustness of GRNs—an
important problem of interest in evolutionary biology—more efficiently than the
classical simulation method. We specify the property in linear temporal logic.
We employ symbolic bounded model checking and SMT solving to compute the space
of GRNs that satisfy the property, which amounts to synthesizing a set of linear
constraints on the weights.

text: One of the major challenges in physically based modelling is making simulations
efficient. Adaptive models provide an essential solution to these efficiency goals.
These models are able to self-adapt in space and time, attempting to provide the
best possible compromise between accuracy and speed. This survey reviews the adaptive
solutions proposed so far in computer graphics. Models are classified according
to the strategy they use for adaptation, from time-stepping and freezing techniques
to geometric adaptivity in the form of structured grids, meshes and particles.
Applications range from fluids, through deformable bodies, to articulated solids.

text: High-harmonic spectroscopy driven by circularly polarized laser pulses and
their counterrotating second harmonic is a new branch of attosecond science which
currently lacks quantitative interpretations. We extend this technique to the
midinfrared regime and record detailed high-harmonic spectra of several rare-gas
atoms. These results are compared with the solution of the Schrödinger equation
in three dimensions and calculations based on the strong-field approximation that
incorporate accurate scattering-wave recombination matrix elements. A quantum-orbit
analysis of these results provides a transparent interpretation of the measured
intensity ratios of symmetry-allowed neighboring harmonics in terms of (i) a set
of propensity rules related to the angular momentum of the atomic orbitals, (ii)
atom-specific matrix elements related to their electronic structure, and (iii)
the interference of the emissions associated with electrons in orbitals corotating
or counterrotating with the laser fields. These results provide the foundation
for a quantitative understanding of bicircular high-harmonic spectroscopy.

text: Strong-field photoelectron holography and laser-induced electron diffraction
(LIED) are two powerful emerging methods for probing the ultrafast dynamics of
molecules. However, both of them have remained restricted to static systems and
to nuclear dynamics induced by strong-field ionization. Here we extend these promising
methods to image purely electronic valence-shell dynamics in molecules using photoelectron
holography. In the same experiment, we use LIED and photoelectron holography simultaneously,
to observe coupled electronic-rotational dynamics taking place on similar timescales.
These results offer perspectives for imaging ultrafast dynamics of molecules on
femtosecond to attosecond timescales.

text: We present a theoretical formalism for the calculation of attosecond delays
in molecular photoionization. It is shown how delays relevant to one-photon-ionization,
also known as Eisenbud-Wigner-Smith delays, can be obtained from the complex dipole
matrix elements provided by molecular quantum scattering theory. These results
are used to derive formulae for the delays measured by two-photon attosecond interferometry
based on an attosecond pulse train and a dressing femtosecond infrared pulse.
These effective delays are first expressed in the molecular frame where maximal
information about the molecular photoionization dynamics is available. The effects
of averaging over the emission direction of the electron and the molecular orientation
are introduced analytically. We illustrate this general formalism for the case
of two polyatomic molecules. N2O serves as an example of a polar linear molecule
characterized by complex photoionization dynamics resulting from the presence
of molecular shape resonances. H2O illustrates the case of a non-linear molecule
with comparably simple photoionization dynamics resulting from a flat continuum.
Our theory establishes the foundation for interpreting measurements of the photoionization
dynamics of all molecules by attosecond metrology.

text: Time-resolved x-ray absorption spectroscopy (TR-XAS) has so far practically
been limited to large-scale facilities, to subpicosecond temporal resolution,
and to the condensed phase. We report the realization of TR-XAS with a temporal
resolution in the low femtosecond range by developing a tabletop high-harmonic
source reaching up to 350 electron volts, thus partially covering the spectral
region of 280 to 530 electron volts, where water is transmissive. We used this
source to follow previously unexamined light-induced chemical reactions in the
lowest electronic states of isolated CF4+ and SF6+ molecules in the gas phase.
By probing element-specific core-to-valence transitions at the carbon K-edge or
the sulfur L-edges, we characterized their reaction paths and observed the effect
of symmetry breaking through the splitting of absorption bands and Rydberg-valence
mixing induced by the geometry changes.

text: Attosecond delays between photoelectron wave packets emitted from different
electronic shells are now well established. Is there any delay between electrons
originating from the same electronic shell but leaving the cation in different
fine-structure states? This question is relevant for all attosecond photoemission
studies involving heavy elements, be it atoms, molecules or solids. We answer
this fundamental question by measuring energy-dependent delays between photoelectron
wave packets associated with the 2P3/2 and 2P1/2 components of the electronic
groundstates of Xe+ and Kr+. We observe delays reaching up to 33±6 as in the case
of Xe. Our results are compared with two state-of-the-art theories. Whereas both
theories quantitatively agree with the results obtained for Kr, neither of them
fully reproduces the experimental results in Xe. Performing delay measurements
very close to the ionization thresholds, we compare the agreement of several analytical
formulas for the continuum-continuum delays with experimental data. Our results
show an important influence of spin-orbit coupling on attosecond photoionization
delays, highlight the requirement for additional theory development, and offer
a precision benchmark for such work.

text: High-harmonic spectroscopy driven by circularly polarized laser pulses and
their counterrotating second harmonic is a new branch of attosecond science which
currently lacks quantitative interpretations. We extend this technique to the
midinfrared regime and record detailed high-harmonic spectra of several rare-gas
atoms. These results are compared with the solution of the Schrödinger equation
in three dimensions and calculations based on the strong-field approximation that
incorporate accurate scattering-wave recombination matrix elements. A quantum-orbit
analysis of these results provides a transparent interpretation of the measured
intensity ratios of symmetry-allowed neighboring harmonics in terms of (i) a set
of propensity rules related to the angular momentum of the atomic orbitals, (ii)
atom-specific matrix elements related to their electronic structure, and (iii)
the interference of the emissions associated with electrons in orbitals corotating
or counterrotating with the laser fields. These results provide the foundation
for a quantitative understanding of bicircular high-harmonic spectroscopy.

system such that there exists a control strategy to ensure that the trajectories
satisfy a temporal logic specification with probability 1 (almost-surely). We
focus on discrete-time, stochastic linear dynamics and specifications given as
formulas of the Generalized Reactivity(1) fragment of Linear Temporal Logic over
linear predicates in the states of the system. We propose a solution based on
iterative abstraction-refinement, and turn-based 2-player probabilistic games.
While the theoretical guarantee of our algorithm after any finite number of iterations
is only a partial solution, we show that if our algorithm terminates, then the
result is the set of all satisfying initial states. Moreover, for any (partial)
solution our algorithm synthesizes witness control strategies to ensure almost-sure
satisfaction of the temporal logic specification. While the proposed algorithm
guarantees progress and soundness in every iteration, it is computationally demanding.
We offer an alternative, more efficient solution for the reachability properties
that decomposes the problem into a series of smaller problems of the same type.
All algorithms are demonstrated on an illustrative case study.

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.
