text: 'Tunneling of a particle through a potential barrier remains one of the most
remarkable quantum phenomena. Owing to advances in laser technology, electric
fields comparable to those electrons experience in atoms are readily generated
and open opportunities to dynamically investigate the process of electron tunneling
through the potential barrier formed by the superposition of both laser and atomic
fields. Attosecond-time and angstrom-space resolution of the strong laser-field
technique allow to address fundamental questions related to tunneling, which are
still open and debated: Which time is spent under the barrier and what momentum
is picked up by the particle in the meantime? In this combined experimental and
theoretical study we demonstrate that for strong-field ionization the leading
quantum mechanical Wigner treatment for the time resolved description of tunneling
is valid. We achieve a high sensitivity on the tunneling barrier and unambiguously
isolate its effects by performing a differential study of two systems with almost
identical tunneling geometry. Moreover, working with a low frequency laser, we
essentially limit the non-adiabaticity of the process as a major source of uncertainty.
The agreement between experiment and theory implies two substantial corrections
with respect to the widely employed quasiclassical treatment: In addition to a
non-vanishing longitudinal momentum along the laser field-direction we provide
clear evidence for a non-zero tunneling time delay. This addresses also the fundamental
question how the transition occurs from the tunnel barrier to free space classical
evolution of the ejected electron.'

text: 'This review captures the synthesis, assembly, properties, and applications
of copper chalcogenide NCs, which have achieved significant research interest
in the last decade due to their compositional and structural versatility. The
outstanding functional properties of these materials stems from the relationship
between their band structure and defect concentration, including charge carrier
concentration and electronic conductivity character, which consequently affects
their optoelectronic, optical, and plasmonic properties. This, combined with several
metastable crystal phases and stoichiometries and the low energy of formation
of defects, makes the reproducible synthesis of these materials, with tunable
parameters, remarkable. Further to this, the review captures the progress of the
hierarchical assembly of these NCs, which bridges the link between their discrete
and collective properties. Their ubiquitous application set has cross-cut energy
conversion (photovoltaics, photocatalysis, thermoelectrics), energy storage (lithium-ion
batteries, hydrogen generation), emissive materials (plasmonics, LEDs, biolabelling),
sensors (electrochemical, biochemical), biomedical devices (magnetic resonance
imaging, X-ray computer tomography), and medical therapies (photochemothermal
therapies, immunotherapy, radiotherapy, and drug delivery). The confluence of
advances in the synthesis, assembly, and application of these NCs in the past
decade has the potential to significantly impact society, both economically and
environmentally. '

text: The conversion of thermal energy to electricity and vice versa by means of
solid state thermoelectric devices is extremely appealing. However, its cost-effectiveness
is seriously hampered by the relatively high production cost and low efficiency
of current thermoelectric materials and devices. To overcome present challenges
and enable a successful deployment of thermoelectric systems in their wide application
range, materials with significantly improved performance need to be developed.
Nanostructuration can help in several ways to reach the very particular group
of properties required to achieve high thermoelectric performances. Nanodomains
inserted within a crystalline matrix can provide large charge carrier concentrations
without strongly influencing their mobility, thus allowing to reach very high
electrical conductivities. Nanostructured materials contain numerous grain boundaries
that efficiently scatter mid- and long-wavelength phonons thus reducing the thermal
conductivity. Furthermore, nanocrystalline domains can enhance the Seebeck coefficient
by modifying the density of states and/or providing type- and energy-dependent
charge carrier scattering. All these advantages can only be reached when engineering
a complex type of material, nanocomposites, with exquisite control over structural
and chemical parameters at multiple length scales. Since current conventional
nanomaterial production technologies lack such level of control, alternative strategies
need to be developed and adjusted to the specifics of the field. A particularly
suitable approach to produce nanocomposites with unique level of control over
their structural and compositional parameters is their bottom-up engineering from
solution-processed nanoparticles. In this work, we review the state-of-the-art
of this technology applied to the thermoelectric field, including the synthesis
of nanoparticles of suitable materials with precisely engineered composition and
surface chemistry, their combination and consolidation into nanostructured materials,
the strategies to electronically dope such materials and the attempts to fabricate
thermoelectric devices using nanoparticle-based nanopowders and inks.

text: "Branched nanocrystals (NCs) enable high atomic surface exposure within a
crystalline network that provides avenues for charge transport. This combination
of properties makes branched NCs particularly suitable for a range of applications
where both interaction with the media and charge transport are involved. Herein
we report on the colloidal synthesis of branched ceria NCs by means of a ligand-mediated
overgrowth mechanism. In particular, the differential coverage of oleic acid as
an X-type ligand at ceria facets with different atomic density, atomic coordination
deficiency, and oxygen vacancy density resulted in a preferential growth in the
[111] direction and thus in the formation of ceria octapods. Alcohols, through
an esterification alcoholysis reaction, promoted faster growth rates that translated
into nanostructures with higher geometrical complexity, increasing the branch
aspect ratio and triggering the formation of side branches. On the other hand,
the presence of water resulted in a significant reduction of the growth rate,
decreasing the reaction yield and eliminating side branching, which we associate
to a blocking of the surface reaction sites or a displacement of the alcoholysis
reaction. Overall, adjusting the amounts of each chemical, well-defined branched
ceria NCs with tuned number, thickness, and length of branches and with overall
size ranging from 5 to 45 nm could be produced. We further demonstrate that such
branched ceria NCs are able to provide higher surface areas and related oxygen
storage capacities (OSC) than quasi-spherical NCs.\r\n\r\n"

text: 'Three-dimensional topological insulators are bulk insulators with Z 2 topological
electronic order that gives rise to conducting light-like surface states. These
surface electrons are exceptionally resistant to localization by non-magnetic
disorder, and have been adopted as the basis for a wide range of proposals to
achieve new quasiparticle species and device functionality. Recent studies have
yielded a surprise by showing that in spite of resisting localization, topological
insulator surface electrons can be reshaped by defects into distinctive resonance
states. Here we use numerical simulations and scanning tunnelling microscopy data
to show that these resonance states have significance well beyond the localized
regime usually associated with impurity bands. At native densities in the model
Bi2X3 (X=Bi, Te) compounds, defect resonance states are predicted to generate
a new quantum basis for an emergent electron gas that supports diffusive electrical
transport. '

text: We used femtosecond optical pump-probe spectroscopy to study the photoinduced
change in reflectivity of thin films of the electron-doped cuprate La2-xCexCuO4
(LCCO) with dopings of x=0.08 (underdoped) and x=0.11 (optimally doped). Above
Tc, we observe fluence-dependent relaxation rates that begin at a temperature
similar to the one where transport measurements first show signatures of antiferromagnetic
correlations. Upon suppressing superconductivity with a magnetic field, it is
found that the fluence and temperature dependence of relaxation rates are consistent
with bimolecular recombination of electrons and holes across a gap (2ΔAF) originating
from antiferromagnetic correlations which comprise the pseudogap in electron-doped
cuprates. This can be used to learn about coupling between electrons and high-energy
(ω>2ΔAF) excitations in these compounds and set limits on the time scales on
which antiferromagnetic correlations are static.

text: 'We use a three-pulse ultrafast optical spectroscopy to study the relaxation
processes in a frustrated Mott insulator Na2IrO3. By being able to independently
produce the out-of-equilibrium bound states (excitons) of doublons and holons
with the first pulse and suppress the underlying antiferromagnetic order with
the second one, we were able to elucidate the relaxation mechanism of quasiparticles
in this system. By observing the difference in the exciton dynamics in the magnetically
ordered and disordered phases we found that the mass of this quasiparticle is
mostly determined by its interaction with the surrounding spins. '

text: 'We show that very weak topological assumptions are enough to ensure the existence
of a Helly-type theorem. More precisely, we show that for any non-negative integers
b and d there exists an integer h(b, d) such that the following holds. If F is
a finite family of subsets of Rd such that βi(∩G)≤b for any G⊊F and every 0 ≤
i ≤ [d/2]-1 then F has Helly number at most h(b, d). Here βi denotes the reduced
Z2-Betti numbers (with singular homology). These topological conditions are sharp:
not controlling any of these [d/2] first Betti numbers allow for families with
unbounded Helly number. Our proofs combine homological non-embeddability results
with a Ramsey-based approach to build, given an arbitrary simplicial complex K,
some well-behaved chain map C*(K)→C*(Rd).'

text: 'Parallel implementations of stochastic gradient descent (SGD) have received
significant research attention, thanks to its excellent scalability properties.
A fundamental barrier when parallelizing SGD is the high bandwidth cost of communicating
gradient updates between nodes; consequently, several lossy compresion heuristics
have been proposed, by which nodes only communicate quantized gradients. Although
effective in practice, these heuristics do not always converge. In this paper,
we propose Quantized SGD (QSGD), a family of compression schemes with convergence
guarantees and good practical performance. QSGD allows the user to smoothly trade
off communication bandwidth and convergence time: nodes can adjust the number
of bits sent per iteration, at the cost of possibly higher variance. We show that
this trade-off is inherent, in the sense that improving it past some threshold
would violate information-theoretic lower bounds. QSGD guarantees convergence
for convex and non-convex objectives, under asynchrony, and can be extended to
stochastic variance-reduced techniques. When applied to training deep neural networks
for image classification and automated speech recognition, QSGD leads to significant
reductions in end-to-end training time. For instance, on 16GPUs, we can train
the ResNet-152 network to full accuracy on ImageNet 1.8 × faster than the full-precision
variant. '

text: 'Recently there has been significant interest in training machine-learning
models at low precision: by reducing precision, one can reduce computation and
communication by one order of magnitude. We examine training at reduced precision,
both from a theoretical and practical perspective, and ask: is it possible to
train models at end-to-end low precision with provable guarantees? Can this lead
to consistent order-of-magnitude speedups? We mainly focus on linear models, and
the answer is yes for linear models. We develop a simple framework called ZipML
based on one simple but novel strategy called double sampling. Our ZipML framework
is able to execute training at low precision with no bias, guaranteeing convergence,
whereas naive quanti- zation would introduce significant bias. We val- idate our
framework across a range of applica- tions, and show that it enables an FPGA proto-
type that is up to 6.5 × faster than an implemen- tation using full 32-bit precision.
We further de- velop a variance-optimal stochastic quantization strategy and show
that it can make a significant difference in a variety of settings. When applied
to linear models together with double sampling, we save up to another 1.7 × in
data movement compared with uniform quantization. When training deep networks
with quantized models, we achieve higher accuracy than the state-of-the- art XNOR-Net. '

text: Pancreatic cancer has a five-year survival rate of ~8%, with characteristic
molecular heterogeneity and restricted treatment options. Targeting metabolism
has emerged as a potentially effective therapeutic strategy for cancers such as
pancreatic cancer, which are driven by genetic alterations that are not tractable
drug targets. Although somatic mitochondrial genome (mtDNA) mutations have been
observed in various tumors types, understanding of metabolic genotype-phenotype
relationships is limited.

text: Complex I (NADH:ubiquinone oxidoreductase) plays a central role in cellular
energy generation, contributing to the proton motive force used to produce ATP.
It couples the transfer of two electrons between NADH and quinone to translocation
of four protons across the membrane. It is the largest protein assembly of bacterial
and mitochondrial respiratory chains, composed, in mammals, of up to 45 subunits
with a total molecular weight of ∼1 MDa. Bacterial enzyme is about half the size,
providing the important “minimal” model of complex I. The l-shaped complex consists
of a hydrophilic arm, where electron transfer occurs, and a membrane arm, where
proton translocation takes place. Previously, we have solved the crystal structures
of the hydrophilic domain of complex I from Thermus thermophilus and of the membrane
domain from Escherichia coli, followed by the atomic structure of intact, entire
complex I from T. thermophilus. Recently, we have solved by cryo-EM a first complete
atomic structure of mammalian (ovine) mitochondrial complex I. Core subunits are
well conserved from the bacterial version, whilst supernumerary subunits form
an interlinked, stabilizing shell around the core. Subunits containing additional
cofactors, including Zn ion, NADPH and phosphopantetheine, probably have regulatory
roles. Dysfunction of mitochondrial complex I is implicated in many human neurodegenerative
diseases. The structure of mammalian enzyme provides many insights into complex
I mechanism, assembly, maturation and dysfunction, allowing detailed molecular
analysis of disease-causing mutations.

text: The Loschmidt echo, defined as the overlap between quantum wave function evolved
with different Hamiltonians, quantifies the sensitivity of quantum dynamics to
perturbations and is often used as a probe of quantum chaos. In this work we consider
the behavior of the Loschmidt echo in the many-body localized phase, which is
characterized by emergent local integrals of motion and provides a generic example
of nonergodic dynamics. We demonstrate that the fluctuations of the Loschmidt
echo decay as a power law in time in the many-body localized phase, in contrast
to the exponential decay in few-body ergodic systems. We consider the spin-echo
generalization of the Loschmidt echo and argue that the corresponding correlation
function saturates to a finite value in localized systems. Slow, power-law decay
of fluctuations of such spin-echo-type overlap is related to the operator spreading
and is present only in the many-body localized phase, but not in a noninteracting
Anderson insulator. While most of the previously considered probes of dephasing
dynamics could be understood by approximating physical spin operators with local
integrals of motion, the Loschmidt echo and its generalizations crucially depend
on the full expansion of the physical operators via local integrals of motion
operators, as well as operators which flip local integrals of motion. Hence these
probes allow one to get insights into the relation between physical operators
and local integrals of motion and access the operator spreading in the many-body
localized phase.

text: We consider last passage percolation (LPP) models with exponentially distributed
random variables, which are linked to the totally asymmetric simple exclusion
process (TASEP). The competition interface for LPP was introduced and studied
in Ferrari and Pimentel (2005a) for cases where the corresponding exclusion process
had a rarefaction fan. Here we consider situations with a shock and determine
the law of the fluctuations of the competition interface around its deter- ministic
law of large number position. We also study the multipoint distribution of the
LPP around the shock, extending our one-point result of Ferrari and Nejjar (2015).

text: 'Spinning tops and yo-yos have long fascinated cultures around the world with
their unexpected, graceful motions that seemingly elude gravity. Yet, due to the
exceeding difficulty of creating stably spinning objects of asymmetric shape in
a manual trial-and-error process, there has been little departure from rotationally
symmetric designs. With modern 3D printing technologies, however, we can manufacture
shapes of almost unbounded complexity at the press of a button, shifting this
design complexity toward computation. In this article, we describe an algorithm
to generate designs for spinning objects by optimizing their mass distribution:
as input, the user provides a solid 3D model and a desired axis of rotation. Our
approach then modifies the interior mass distribution such that the principal
directions of the moment of inertia align with the target rotation frame. To create
voids inside the model, we represent its volume with an adaptive multiresolution
voxelization and optimize the discrete voxel fill values using a continuous, nonlinear
formulation. We further optimize for rotational stability by maximizing the dominant
principal moment. Our method is well-suited for a variety of 3D printed models,
ranging from characters to abstract shapes. We demonstrate tops and yo-yos that
spin surprisingly stably despite their asymmetric appearance.'

text: Most kinesin motors move in only one direction along microtubules. Members
of the kinesin-5 subfamily were initially described as unidirectional plus-end-directed
motors and shown to produce piconewton forces. However, some fungal kinesin-5
motors are bidirectional. The force production of a bidirectional kinesin-5 has
not yet been measured. Therefore, it remains unknown whether the mechanism of
the unconventional minus-end-directed motility differs fundamentally from that
of plus-end-directed stepping. Using force spectroscopy, we have measured here
the forces that ensembles of purified budding yeast kinesin-5 Cin8 produce in
microtubule gliding assays in both plus- and minus-end direction. Correlation
analysis of pause forces demonstrated that individual Cin8 molecules produce additive
forces in both directions of movement. In ensembles, Cin8 motors were able to
produce single-motor forces up to a magnitude of ∼1.5 pN. Hence, these properties
appear to be conserved within the kinesin-5 subfamily. Force production was largely
independent of the directionality of movement, indicating similarities between
the motility mechanisms for both directions. These results provide constraints
for the development of models for the bidirectional motility mechanism of fission
yeast kinesin-5 and provide insight into the function of this mitotic motor.

text: The social insects bees, wasps, ants, and termites are species-rich, occur
in many habitats, and often constitute a large part of the biomass. Many are also
invasive, including species of termites, the red imported fire ant, and the Argentine
ant. While invasive social insects have been a problem in Southern Europe for
some time, Central Europa was free of invasive ant species until recently because
most ants are adapted to warmer climates. Only in the 1990s, did Lasius neglectus,
a close relative of the common black garden ant, arrive in Germany. First described
in 1990 based on individuals collected in Budapest, the species has since been
detected for example in France, Germany, Spain, England, and Kyrgyzstan. The species
is spread with soil during construction work or plantings, and L. neglectus therefore
is often found in parks and botanical gardens. Another invasive ant now spreading
in southern Germany is Formica fuscocinerea, which occurs along rivers, including
in the sandy floodplains of the river Isar. As is typical of pioneer species,
F. fuscocinerea quickly becomes extremely abundant and therefore causes problems
for example on playgrounds in Munich. All invasive ant species are characterized
by cooperation across nests, leading to strongly interconnected, very large super-colonies.
The resulting dominance results in the extinction of native ant species as well
as other arthropod species and thus in the reduction of biodiversity.

text: We investigate transient behaviors induced by magnetic fields on the dynamics
of the flow of a ferrofluid in the gap between two concentric, independently rotating
cylinders. Without applying any magnetic fields, we uncover emergence of flow
states constituted by a combination of a localized spiral state (SPIl) in the
top and bottom of the annulus and different multi-cell flow states (SPI2v, SPI3v)
with toroidally closed vortices in the interior of the bulk (SPIl+2v = SPIl +
SPI2v and SPIl+3v = SPIl + SPI3v). However, when a magnetic field is presented,
we observe the transient behaviors between multi-cell states passing through two
critical thresholds in a strength of an axial (transverse) magnetic field. Before
the first critical threshold of a magnetic field strength, multi-stable states
with different number of cells could be observed. After the first critical threshold,
we find the transient behavior between the three- and two-cell flow states. For
more strength of magnetic field or after the second critical threshold, we discover
that multi-cell states are disappeared and a localized spiral state remains to
be stimulated. The studied transient behavior could be understood by the investigation
of various quantities including a modal kinetic energy, a mode amplitude of the
radial velocity, wavenumber, angular momentum, and torque. In addition, the emergence
of new flow states and the transient behavior between their states in ferrofluidic
flows indicate that richer and potentially controllable dynamics through magnetic
fields could be possible in ferrofluic flow.

text: The computation of the winning set for parity objectives and for Streett objectives
in graphs as well as in game graphs are central problems in computer-aided verification,
with application to the verification of closed systems with strong fairness conditions,
the verification of open systems, checking interface compatibility, well-formedness
of specifications, and the synthesis of reactive systems. We show how to compute
the winning set on n vertices for (1) parity-3 (aka one-pair Streett) objectives
in game graphs in time O(n5/2) and for (2) k-pair Streett objectives in graphs
in time O(n2+nklogn). For both problems this gives faster algorithms for dense
graphs and represents the first improvement in asymptotic running time in 15 years.

text: 'The edit distance between two words w 1 , w 2 is the minimal number of word
operations (letter insertions, deletions, and substitutions) necessary to transform
w 1 to w 2 . The edit distance generalizes to languages L 1 , L 2 , where the
edit distance from L 1 to L 2 is the minimal number k such that for every word
from L 1 there exists a word in L 2 with edit distance at most k . We study the
edit distance computation problem between pushdown automata and their subclasses.
The problem of computing edit distance to a pushdown automaton is undecidable,
and in practice, the interesting question is to compute the edit distance from
a pushdown automaton (the implementation, a standard model for programs with recursion)
to a regular language (the specification). In this work, we present a complete
picture of decidability and complexity for the following problems: (1) deciding
whether, for a given threshold k , the edit distance from a pushdown automaton
to a finite automaton is at most k , and (2) deciding whether the edit distance
from a pushdown automaton to a finite automaton is finite. '
