text: "We study the problem of learning from multiple untrusted data sources, a
scenario of increasing practical relevance given the recent emergence of crowdsourcing
and collaborative learning paradigms. Specifically, we analyze the situation in
which a learning system obtains datasets from multiple sources, some of which
might be biased or even adversarially perturbed. It is\r\nknown that in the single-source
case, an adversary with the power to corrupt a fixed fraction of the training
data can prevent PAC-learnability, that is, even in the limit of infinitely much
training data, no learning system can approach the optimal test error. In this
work we show that, surprisingly, the same is not true in the multi-source setting,
where the adversary can arbitrarily\r\ncorrupt a fixed fraction of the data sources.
Our main results are a generalization bound that provides finite-sample guarantees
for this learning setting, as well as corresponding lower bounds. Besides establishing
PAC-learnability our results also show that in a cooperative learning setting
sharing data with other parties has provable benefits, even if some\r\nparticipants
are malicious. "

text: "The design and implementation of efficient concurrent data structures have\r\nseen
significant attention. However, most of this work has focused on\r\nconcurrent
data structures providing good \\emph{worst-case} guarantees. In real\r\nworkloads,
objects are often accessed at different rates, since access\r\ndistributions may
be non-uniform. Efficient distribution-adaptive data\r\nstructures are known in
the sequential case, e.g. the splay-trees; however,\r\nthey often are hard to
translate efficiently in the concurrent case.\r\n In this paper, we investigate
distribution-adaptive concurrent data\r\nstructures and propose a new design called
the splay-list. At a high level, the\r\nsplay-list is similar to a standard skip-list,
with the key distinction that\r\nthe height of each element adapts dynamically
to its access rate: popular\r\nelements ``move up,'' whereas rarely-accessed elements
decrease in height. We\r\nshow that the splay-list provides order-optimal amortized
complexity bounds for\r\na subset of operations while being amenable to efficient
concurrent\r\nimplementation. Experimental results show that the splay-list can
leverage\r\ndistribution-adaptivity to improve on the performance of classic concurrent\r\ndesigns,
and can outperform the only previously-known distribution-adaptive\r\ndesign in
certain settings."

text: Several realistic spin-orbital models for transition metal oxides go beyond
the classical expectations and could be understood only by employing the quantum
entanglement. Experiments on these materials confirm that spin-orbital entanglement
has measurable consequences. Here, we capture the essential features of spin-orbital
entanglement in complex quantum matter utilizing 1D spin-orbital model which accommodates
SU(2)⊗SU(2) symmetric Kugel-Khomskii superexchange as well as the Ising on-site
spin-orbit coupling. Building on the results obtained for full and effective models
in the regime of strong spin-orbit coupling, we address the question whether the
entanglement found on superexchange bonds always increases when the Ising spin-orbit
coupling is added. We show that (i) quantum entanglement is amplified by strong
spin-orbit coupling and, surprisingly, (ii) almost classical disentangled states
are possible. We complete the latter case by analyzing how the entanglement existing
for intermediate values of spin-orbit coupling can disappear for higher values
of this coupling.

text: Discrete-time Markov Chains (MCs) and Markov Decision Processes (MDPs) are
two standard formalisms in system analysis. Their main associated quantitative
objectives are hitting probabilities, discounted sum, and mean payoff. Although
there are many techniques for computing these objectives in general MCs/MDPs,
they have not been thoroughly studied in terms of parameterized algorithms, particularly
when treewidth is used as the parameter. This is in sharp contrast to qualitative
objectives for MCs, MDPs and graph games, for which treewidth-based algorithms
yield significant complexity improvements. In this work, we show that treewidth
can also be used to obtain faster algorithms for the quantitative problems. For
an MC with n states and m transitions, we show that each of the classical quantitative
objectives can be computed in O((n+m)⋅t2) time, given a tree decomposition
of the MC with width t. Our results also imply a bound of O(κ⋅(n+m)⋅t2) for
each objective on MDPs, where κ is the number of strategy-iteration refinements
required for the given input and objective. Finally, we make an experimental evaluation
of our new algorithms on low-treewidth MCs and MDPs obtained from the DaCapo benchmark
suite. Our experiments show that on low-treewidth MCs and MDPs, our algorithms
outperform existing well-established methods by one or more orders of magnitude.

text: 'A simple drawing D(G) of a graph G is one where each pair of edges share
at most one point: either a common endpoint or a proper crossing. An edge e in
the complement of G can be inserted into D(G) if there exists a simple drawing
of G+e extending D(G). As a result of Levi’s Enlargement Lemma, if a drawing
is rectilinear (pseudolinear), that is, the edges can be extended into an arrangement
of lines (pseudolines), then any edge in the complement of G can be inserted.
In contrast, we show that it is NP -complete to decide whether one edge can
be inserted into a simple drawing. This remains true even if we assume that the
drawing is pseudocircular, that is, the edges can be extended to an arrangement
of pseudocircles. On the positive side, we show that, given an arrangement of
pseudocircles A and a pseudosegment σ , it can be decided in polynomial time
whether there exists a pseudocircle Φσ extending σ for which A∪{Φσ} is
again an arrangement of pseudocircles.'

text: Mitochondrial complex I couples NADH:ubiquinone oxidoreduction to proton pumping
by an unknown mechanism. Here, we present cryo-electron microscopy structures
of ovine complex I in five different conditions, including turnover, at resolutions
up to 2.3 to 2.5 angstroms. Resolved water molecules allowed us to experimentally
define the proton translocation pathways. Quinone binds at three positions along
the quinone cavity, as does the inhibitor rotenone that also binds within subunit
ND4. Dramatic conformational changes around the quinone cavity couple the redox
reaction to proton translocation during open-to-closed state transitions of the
enzyme. In the induced deactive state, the open conformation is arrested by the
ND6 subunit. We propose a detailed molecular coupling mechanism of complex I,
which is an unexpected combination of conformational changes and electrostatic
interactions.

text: In vitro work revealed that excitatory synaptic inputs to hippocampal inhibitory
interneurons could undergo Hebbian, associative, or non-associative plasticity.
Both behavioral and learning-dependent reorganization of these connections has
also been demonstrated by measuring spike transmission probabilities in pyramidal
cell-interneuron spike cross-correlations that indicate monosynaptic connections.
Here we investigated the activity-dependent modification of these connections
during exploratory behavior in rats by optogenetically inhibiting pyramidal cell
and interneuron subpopulations. Light application and associated firing alteration
of pyramidal and interneuron populations led to lasting changes in pyramidal-interneuron
connection weights as indicated by spike transmission changes. Spike transmission
alterations were predicted by the light-mediated changes in the number of pre-
and postsynaptic spike pairing events and by firing rate changes of interneurons
but not pyramidal cells. This work demonstrates the presence of activity-dependent
associative and non-associative reorganization of pyramidal-interneuron connections
triggered by the optogenetic modification of the firing rate and spike synchrony
of cells.

text: "In ecology, climate and other fields, (sub)systems have been identified that
can transition into a qualitatively different state when a critical threshold
or tipping point in a driving process is crossed. An understanding of those tipping
elements is of great interest given the increasing influence of humans on the
biophysical Earth system. Complex interactions exist between tipping elements,
e.g. physical mechanisms connect subsystems of the climate system. Based on earlier
work on such coupled nonlinear systems, we systematically assessed the qualitative
long-term behaviour of interacting tipping elements. We developed an understanding
of the consequences of interactions\r\non the tipping behaviour allowing for tipping
cascades to emerge under certain conditions. The (narrative) application of\r\nthese
qualitative results to real-world examples of interacting tipping elements indicates
that tipping cascades with profound consequences may occur: the interacting Greenland
ice sheet and thermohaline ocean circulation might tip before the tipping points
of the isolated subsystems are crossed. The eutrophication of the first lake in
a lake chain might propagate through the following lakes without a crossing of
their individual critical nutrient input levels. The possibility of emerging cascading
tipping dynamics calls for the development of a unified theory of interacting
tipping elements and the quantitative analysis of interacting real-world tipping
elements."

coupling of cysteine oxidation, disulfide bond formation and structure formation
in nascent chains has remained elusive. Here, we investigate the eye-lens protein
γB-crystallin in the ribosomal exit tunnel. Using mass spectrometry, theoretical
simulations, dynamic nuclear polarization-enhanced solid-state nuclear magnetic
resonance and cryo-electron microscopy, we show that thiol groups of cysteine
residues undergo S-glutathionylation and S-nitrosylation and form non-native disulfide
bonds. Thus, covalent modification chemistry occurs already prior to nascent chain
release as the ribosome exit tunnel provides sufficient space even for disulfide
bond formation which can guide protein folding.

text: "Research in the field of colloidal semiconductor nanocrystals (NCs) has progressed
tremendously, mostly because of their exceptional optoelectronic properties. Core@shell
NCs, in which one or more inorganic layers overcoat individual NCs, recently received
significant attention due to their remarkable optical characteristics. Reduced
Auger recombination, suppressed blinking, and enhanced carrier multiplication
are among the merits of core@shell NCs. Despite their importance in device development,
the influence of the shell and the surface modification of the core@shell NC assemblies
on the charge carrier transport remains a pertinent research objective. Type-II
PbTe@PbS core@shell NCs, in which exclusive electron transport was demonstrated,
still exhibit instability of their electron \r\n ransport. Here, we demonstrate
the enhancement of electron transport and stability in PbTe@PbS core@shell NC
assemblies using iodide as a surface passivating ligand. The combination of the
PbS shelling and the use of the iodide ligand contributes to the addition of one
mobile electron for each core@shell NC. Furthermore, both electron mobility and
on/off current modulation ratio values of the core@shell NC field-effect transistor
are steady with the usage of iodide. Excellent stability in these exclusively
electron-transporting core@shell NCs paves the way for their utilization in electronic
devices. "

text: "Appropriately designed nanocomposites allow improving the thermoelectric
performance by several mechanisms, including phonon scattering, modulation doping
and energy filtering, while additionally promoting better mechanical properties
than those of crystalline materials. Here, a strategy for producing Bi2Te3–Cu2xTe
nanocomposites based on the consolidation of heterostructured nanoparticles is
described and the thermoelectric properties of the obtained materials are investigated.
We first detail a two-step solution-based process to produce Bi2Te3–Cu2xTe heteronanostructures,
based on the growth of Cu2xTe nanocrystals on the surface of Bi2Te3 nanowires.
We characterize the structural and chemical properties of the synthesized nanostructures
and of the nanocomposites\r\nproduced by hot-pressing the particles at moderate
temperatures. Besides, the transport properties of the nanocomposites are investigated
as a function of the amount of Cu introduced. Overall, the presence of Cu decreases
the material thermal conductivity through promotion of phonon scattering, modulates
the charge carrier concentration through electron spillover, and increases the
Seebeck coefficient through filtering of charge carriers at energy barriers. These
effects result in an improvement of over 50% of the thermoelectric figure of merit
of Bi2Te3."

text: "Efficiently handling time-triggered and possibly nondeterministic switches\r\nfor
hybrid systems reachability is a challenging task. In this paper we present\r\nan
approach based on conservative set-based enclosure of the dynamics that can\r\nhandle
systems with uncertain parameters and inputs, where the uncertainties\r\nare bound
to given intervals. The method is evaluated on the plant model of an\r\nexperimental
electro-mechanical braking system with periodic controller. In\r\nthis model,
the fast-switching controller dynamics requires simulation time\r\nscales of the
order of nanoseconds. Accurate set-based computations for\r\nrelatively large
time horizons are known to be expensive. However, by\r\nappropriately decoupling
the time variable with respect to the spatial\r\nvariables, and enclosing the
uncertain parameters using interval matrix maps\r\nacting on zonotopes, we show
that the computation time can be lowered to 5000\r\ntimes faster with respect
to previous works. This is a step forward in formal\r\nverification of hybrid
systems because reduced run-times allow engineers to\r\nintroduce more expressiveness
in their models with a relatively inexpensive\r\ncomputational cost."

text: 'The superconducting circuit community has recently discovered the promising
potential of superinductors. These circuit elements have a characteristic impedance
exceeding the resistance quantum RQ ≈ 6.45 kΩ which leads to a suppression of
ground state charge fluctuations. Applications include the realization of hardware
protected qubits for fault tolerant quantum computing, improved coupling to small
dipole moment objects and defining a new quantum metrology standard for the ampere.
In this work we refute the widespread notion that superinductors can only be implemented
based on kinetic inductance, i.e. using disordered superconductors or Josephson
junction arrays. We present modeling, fabrication and characterization of 104
planar aluminum coil resonators with a characteristic impedance up to 30.9 kΩ
at 5.6 GHz and a capacitance down to ≤ 1 fF, with lowloss and a power handling
reaching 108 intra-cavity photons. Geometric superinductors are free of uncontrolled
tunneling events and offer high reproducibility, linearity and the ability to
couple magnetically - properties that significantly broaden the scope of future
quantum circuits. '

text: We consider various modeling levels for spatially homogeneous chemical reaction
systems, namely the chemical master equation, the chemical Langevin dynamics,
and the reaction-rate equation. Throughout we restrict our study to the case where
the microscopic system satisfies the detailed-balance condition. The latter allows
us to enrich the systems with a gradient structure, i.e. the evolution is given
by a gradient-flow equation. We present the arising links between the associated
gradient structures that are driven by the relative entropy of the detailed-balance
steady state. The limit of large volumes is studied in the sense of evolutionary
Γ-convergence of gradient flows. Moreover, we use the gradient structures to derive
hybrid models for coupling different modeling levels.

abstract:
- lang: eng
text: This paper introduces a simple method for simulating highly anisotropic elastoplastic
material behaviors like the dissolution of fibrous phenomena (splintering wood,
shredding bales of hay) and materials composed of large numbers of irregularly‐shaped
bodies (piles of twigs, pencils, or cards). We introduce a simple transformation
of the anisotropic problem into an equivalent isotropic one, and we solve this
new “fictitious” isotropic problem using an existing simulator based on the material
point method. Our approach results in minimal changes to existing simulators,
and it allows us to re‐use popular isotropic plasticity models like the Drucker‐Prager
yield criterion instead of inventing new anisotropic plasticity models for every
phenomenon we wish to simulate.

text: "The “procedural” approach to animating ocean waves is the dominant algorithm
for animating larger bodies of water in\r\ninteractive applications as well as
in off-line productions — it provides high visual quality with a low computational
demand. In this paper, we widen the applicability of procedural water wave animation
with an extension that guarantees the satisfaction of boundary conditions imposed
by terrain while still approximating physical wave behavior. In combination with
a particle system that models wave breaking, foam, and spray, this allows us to
naturally model waves interacting with beaches and rocks. Our system is able to
animate waves at large scales at interactive frame rates on a commodity PC."

text: Resources are rarely distributed uniformly within a population. Heterogeneity
in the concentration of a drug, the quality of breeding sites, or wealth can all
affect evolutionary dynamics. In this study, we represent a collection of properties
affecting the fitness at a given location using a color. A green node is rich
in resources while a red node is poorer. More colors can represent a broader spectrum
of resource qualities. For a population evolving according to the birth-death
Moran model, the first question we address is which structures, identified by
graph connectivity and graph coloring, are evolutionarily equivalent. We prove
that all properly two-colored, undirected, regular graphs are evolutionarily equivalent
(where “properly colored” means that no two neighbors have the same color). We
then compare the effects of background heterogeneity on properly two-colored graphs
to those with alternative schemes in which the colors are permuted. Finally, we
discuss dynamic coloring as a model for spatiotemporal resource fluctuations,
and we illustrate that random dynamic colorings often diminish the effects of
background heterogeneity relative to a proper two-coloring.

text: One of the hallmarks of quantum statistics, tightly entwined with the concept
of topological phases of matter, is the prediction of anyons. Although anyons
are predicted to be realized in certain fractional quantum Hall systems, they
have not yet been unambiguously detected in experiment. Here we introduce a simple
quantum impurity model, where bosonic or fermionic impurities turn into anyons
as a consequence of their interaction with the surrounding many-particle bath.
A cloud of phonons dresses each impurity in such a way that it effectively attaches
fluxes or vortices to it and thereby converts it into an Abelian anyon. The corresponding
quantum impurity model, first, provides a different approach to the numerical
solution of the many-anyon problem, along with a concrete perspective of anyons
as emergent quasiparticles built from composite bosons or fermions. More importantly,
the model paves the way toward realizing anyons using impurities in crystal lattices
as well as ultracold gases. In particular, we consider two heavy electrons interacting
with a two-dimensional lattice crystal in a magnetic field, and show that when
the impurity-bath system is rotated at the cyclotron frequency, impurities behave
as anyons as a consequence of the angular momentum exchange between the impurities
and the bath. A possible experimental realization is proposed by identifying the
statistics parameter in terms of the mean-square distance of the impurities and
the magnetization of the impurity-bath system, both of which are accessible to
experiment. Another proposed application is impurities immersed in a two-dimensional
weakly interacting Bose gas.

text: Breakdown of vascular barriers is a major complication of inflammatory diseases.
Anucleate platelets form blood-clots during thrombosis, but also play a crucial
role in inflammation. While spatio-temporal dynamics of clot formation are well
characterized, the cell-biological mechanisms of platelet recruitment to inflammatory
micro-environments remain incompletely understood. Here we identify Arp2/3-dependent
lamellipodia formation as a prominent morphological feature of immune-responsive
platelets. Platelets use lamellipodia to scan for fibrin(ogen) deposited on the
inflamed vasculature and to directionally spread, to polarize and to govern haptotactic
migration along gradients of the adhesive ligand. Platelet-specific abrogation
of Arp2/3 interferes with haptotactic repositioning of platelets to microlesions,
thus impairing vascular sealing and provoking inflammatory microbleeding. During
infection, haptotaxis promotes capture of bacteria and prevents hematogenic dissemination,
rendering platelets gate-keepers of the inflamed microvasculature. Consequently,
these findings identify haptotaxis as a key effector function of immune-responsive
platelets.
