text: Redox mediators could catalyse otherwise slow and energy-inefficient cycling
of Li-S and Li-O 2 batteries by shuttling electrons/holes between the electrode
and the solid insulating storage materials. For mediators to work efficiently
they need to oxidize the solid with fast kinetics yet the lowest possible overpotential.
Here, we found that when the redox potentials of mediators are tuned via, e.g.,
Li + concentration in the electrolyte, they exhibit distinct threshold potentials,
where the kinetics accelerate several-fold within a range as small as 10 mV. This
phenomenon is independent of types of mediators and electrolyte. The acceleration
originates from the overpotentials required to activate fast Li + /e – extraction
and the following chemical step at specific abundant surface facets. Efficient
redox catalysis at insulating solids requires therefore carefully considering
the surface conditions of the storage materials and electrolyte-dependent redox
potentials, which may be tuned by salt concentrations or solvents.

text: Insufficient understanding of the mechanism that reversibly converts sulphur
into lithium sulphide (Li2S) via soluble polysulphides (PS) hampers the realization
of high performance lithium-sulphur cells. Typically Li2S formation is explained
by direct electroreduction of a PS to Li2S; however, this is not consistent with
the size of the insulating Li2S deposits. Here, we use in situ small and wide
angle X-ray scattering (SAXS/WAXS) to track the growth and dissolution of crystalline
and amorphous deposits from atomic to sub-micron scales during charge and discharge.
Stochastic modelling based on the SAXS data allows quantification of the chemical
phase evolution during discharge and charge. We show that Li2S deposits predominantly
via disproportionation of transient, solid Li2S2 to form primary Li2S crystallites
and solid Li2S4 particles. We further demonstrate that this process happens in
reverse during charge. These findings show that the discharge capacity and rate
capability in Li-S battery cathodes are therefore limited by mass transport through
the increasingly tortuous network of Li2S / Li2S4 / carbon pores rather than electron
transport through a passivating surface film.

text: "The numerical simulation of dynamical phenomena in interacting quantum systems
is a notoriously hard problem. Although a number of promising numerical methods
exist, they often have limited applicability due to the growth of entanglement
or the presence of the so-called sign problem. In this work, we develop an importance
sampling scheme for the simulation of quantum spin dynamics, building on a recent
approach mapping quantum spin systems to classical stochastic processes. The importance
sampling scheme is based on identifying the classical trajectory that yields the
largest contribution to a given quantum observable. An exact transformation is
then carried out to preferentially sample trajectories that are close to the dominant
one. We demonstrate that this approach is capable of reducing the temporal growth
of fluctuations in the stochastic quantities, thus extending the range of accessible
times and system sizes compared to direct sampling. We discuss advantages and
limitations of the proposed approach, outlining directions\r\nfor further developments."

text: AMPA receptor (AMPAR) abundance and positioning at excitatory synapses regulates
the strength of transmission. Changes in AMPAR localisation can enact synaptic
plasticity, allowing long-term information storage, and is therefore tightly controlled.
Multiple mechanisms regulating AMPAR synaptic anchoring have been described, but
with limited coherence or comparison between reports, our understanding of this
process is unclear. Here, combining synaptic recordings from mouse hippocampal
slices and super-resolution imaging in dissociated cultures, we compare the contributions
of three AMPAR interaction domains controlling transmission at hippocampal CA1
synapses. We show that the AMPAR C-termini play only a modulatory role, whereas
the extracellular N-terminal domain (NTD) and PDZ interactions of the auxiliary
subunit TARP γ8 are both crucial, and each is sufficient to maintain transmission.
Our data support a model in which γ8 accumulates AMPARs at the postsynaptic density,
where the NTD further tunes their positioning. This interplay between cytosolic
(TARP γ8) and synaptic cleft (NTD) interactions provides versatility to regulate
synaptic transmission and plasticity.

text: Size control is a fundamental question in biology, showing incremental complexity
in plants, whose cells possess a rigid cell wall. The phytohormone auxin is a
vital growth regulator with central importance for differential growth control.
Our results indicate that auxin-reliant growth programs affect the molecular complexity
of xyloglucans, the major type of cell wall hemicellulose in eudicots. Auxin-dependent
induction and repression of growth coincide with reduced and enhanced molecular
complexity of xyloglucans, respectively. In agreement with a proposed function
in growth control, genetic interference with xyloglucan side decorations distinctly
modulates auxin-dependent differential growth rates. Our work proposes that auxin-dependent
growth programs have a spatially defined effect on xyloglucan’s molecular structure,
which in turn affects cell wall mechanics and specifies differential, gravitropic
hypocotyl growth.

text: 'Stateless model checking (SMC) is one of the standard approaches to the verification
of concurrent programs. As scheduling non-determinism creates exponentially large
spaces of thread interleavings, SMC attempts to partition this space into equivalence
classes and explore only a few representatives from each class. The efficiency
of this approach depends on two factors: (a) the coarseness of the partitioning,
and (b) the time to generate representatives in each class. For this reason, the
search for coarse partitionings that are efficiently explorable is an active research
challenge. In this work we present RVF-SMC , a new SMC algorithm that uses a
novel reads-value-from (RVF) partitioning. Intuitively, two interleavings are
deemed equivalent if they agree on the value obtained in each read event, and
read events induce consistent causal orderings between them. The RVF partitioning
is provably coarser than recent approaches based on Mazurkiewicz and “reads-from”
partitionings. Our experimental evaluation reveals that RVF is quite often a very
effective equivalence, as the underlying partitioning is exponentially coarser
than other approaches. Moreover, RVF-SMC generates representatives very efficiently,
as the reduction in the partitioning is often met with significant speed-ups in
the model checking task.'

text: "Blood – this is what animals use to heal wounds fast and efficient. Plants
do not have blood circulation and their cells cannot move. However, plants have
evolved remarkable capacities to regenerate tissues and organs preventing further
damage. In my PhD research, I studied the wound healing in the Arabidopsis root.
I used a UV laser to ablate single cells in the root tip and observed the consequent
wound healing. Interestingly, the inner adjacent cells induced a\r\ndivision plane
switch and subsequently adopted the cell type of the killed cell to replace it.
We termed this form of wound healing “restorative divisions”. This initial observation
triggered the questions of my PhD studies: How and why do cells orient their division
planes, how do they feel the wound and why does this happen only in inner adjacent
cells.\r\nFor answering these questions, I used a quite simple experimental setup:
5 day - old seedlings were stained with propidium iodide to visualize cell walls
and dead cells; ablation was carried out using a special laser cutter and a confocal
microscope. Adaptation of the novel vertical microscope system made it possible
to observe wounds in real time. This revealed that restorative divisions occur
at increased frequency compared to normal divisions. Additionally,\r\nthe major
plant hormone auxin accumulates in wound adjacent cells and drives the expression
of the wound-stress responsive transcription factor ERF115. Using this as a marker
gene for wound responses, we found that an important part of wound signalling
is the sensing of the collapse of the ablated cell. The collapse causes a radical
pressure drop, which results in strong tissue deformations. These deformations
manifest in an invasion of the now free spot specifically by the inner adjacent
cells within seconds, probably because of higher pressure of the inner tissues.
Long-term imaging revealed that those deformed cells continuously expand towards
the wound hole and that this is crucial for the restorative division. These wound-expanding
cells exhibit an abnormal, biphasic polarity of microtubule arrays\r\nbefore the
division. Experiments inhibiting cell expansion suggest that it is the biphasic
stretching that induces those MT arrays. Adapting the micromanipulator aspiration
system from animal scientists at our institute confirmed the hypothesis that stretching
influences microtubule stability. In conclusion, this shows that microtubules
react to tissue deformation\r\nand this facilitates the observed division plane
switch. This puts mechanical cues and tensions at the most prominent position
for explaining the growth and wound healing properties of plants. Hence, it shines
light onto the importance of understanding mechanical signal transduction. "

text: Indirect reciprocity is a mechanism for the evolution of cooperation based
on social norms. This mechanism requires that individuals in a population observe
and judge each other’s behaviors. Individuals with a good reputation are more
likely to receive help from others. Previous work suggests that indirect reciprocity
is only effective when all relevant information is reliable and publicly available.
Otherwise, individuals may disagree on how to assess others, even if they all
apply the same social norm. Such disagreements can lead to a breakdown of cooperation.
Here we explore whether the predominantly studied ‘leading eight’ social norms
of indirect reciprocity can be made more robust by equipping them with an element
of generosity. To this end, we distinguish between two kinds of generosity. According
to assessment generosity, individuals occasionally assign a good reputation to
group members who would usually be regarded as bad. According to action generosity,
individuals occasionally cooperate with group members with whom they would usually
defect. Using individual-based simulations, we show that the two kinds of generosity
have a very different effect on the resulting reputation dynamics. Assessment
generosity tends to add to the overall noise and allows defectors to invade. In
contrast, a limited amount of action generosity can be beneficial in a few cases.
However, even when action generosity is beneficial, the respective simulations
do not result in full cooperation. Our results suggest that while generosity can
favor cooperation when individuals use the most simple strategies of reciprocity,
it is disadvantageous when individuals use more complex social norms.

type A in detail as well as its connections with quantum XXZ spin chains and trigonometric
Ruijsenaars-Schneider models. Finally we study a limit which produces a K-theoretic
version of results of Givental and Kim, connecting quantum geometry of flag varieties
and Toda lattice.

text: 'The developmental strategies used by progenitor cells to endure a safe journey
from their induction place towards the site of terminal differentiation are still
poorly understood. Here we uncovered a progenitor cell allocation mechanism that
stems from an incomplete process of epithelial delamination that allows progenitors
to coordinate their movement with adjacent extra-embryonic tissues. Progenitors
of the zebrafish laterality organ originate from the surface epithelial enveloping
layer by an apical constriction process of cell delamination. During this process,
progenitors retain long-term apical contacts that enable the epithelial layer
to pull a subset of progenitors along their way towards the vegetal pole. The
remaining delaminated progenitors follow apically-attached progenitors’ movement
by a co-attraction mechanism, avoiding sequestration by the adjacent endoderm,
ensuring their fate and collective allocation at the differentiation site. Thus,
we reveal that incomplete delamination serves as a cellular platform for coordinated
tissue movements during development. Impact Statement: Incomplete delamination
serves as a cellular platform for coordinated tissue movements during development,
guiding newly formed progenitor cell groups to the differentiation site.'

text: The family of feedback alignment (FA) algorithms aims to provide a more biologically
motivated alternative to backpropagation (BP), by substituting the computations
that are unrealistic to be implemented in physical brains. While FA algorithms
have been shown to work well in practice, there is a lack of rigorous theory proofing
their learning capabilities. Here we introduce the first feedback alignment algorithm
with provable learning guarantees. In contrast to existing work, we do not require
any assumption about the size or depth of the network except that it has a single
output neuron, i.e., such as for binary classification tasks. We show that our
FA algorithm can deliver its theoretical promises in practice, surpassing the
learning performance of existing FA methods and matching backpropagation in binary
classification tasks. Finally, we demonstrate the limits of our FA variant when
the number of output neurons grows beyond a certain quantity.

text: We propose a neural information processing system obtained by re-purposing
the function of a biological neural circuit model to govern simulated and real-world
control tasks. Inspired by the structure of the nervous system of the soil-worm,
C. elegans, we introduce ordinary neural circuits (ONCs), defined as the model
of biological neural circuits reparameterized for the control of alternative tasks.
We first demonstrate that ONCs realize networks with higher maximum flow compared
to arbitrary wired networks. We then learn instances of ONCs to control a series
of robotic tasks, including the autonomous parking of a real-world rover robot.
For reconfiguration of the purpose of the neural circuit, we adopt a search-based
optimization algorithm. Ordinary neural circuits perform on par and, in some cases,
significantly surpass the performance of contemporary deep learning models. ONC
networks are compact, 77% sparser than their counterpart neural controllers, and
their neural dynamics are fully interpretable at the cell-level.

text: We introduce in this paper AMT2.0, a tool for qualitative and quantitative
analysis of hybrid continuous and Boolean signals that combine numerical values
and discrete events. The evaluation of the signals is based on rich temporal specifications
expressed in extended signal temporal logic, which integrates timed regular expressions
within signal temporal logic. The tool features qualitative monitoring (property
satisfaction checking), trace diagnostics for explaining and justifying property
violations and specification-driven measurement of quantitative features of the
signal. We demonstrate the tool functionality on several running examples and
case studies, and evaluate its performance.

text: We consider the sum of two large Hermitian matrices A and B with a Haar unitary
conjugation bringing them into a general relative position. We prove that the
eigenvalue density on the scale slightly above the local eigenvalue spacing is
asymptotically given by the free additive convolution of the laws of A and B as
the dimension of the matrix increases. This implies optimal rigidity of the eigenvalues
and optimal rate of convergence in Voiculescu's theorem. Our previous works [4],
[5] established these results in the bulk spectrum, the current paper completely
settles the problem at the spectral edges provided they have the typical square-root
behavior. The key element of our proof is to compensate the deterioration of the
stability of the subordination equations by sharp error estimates that properly
account for the local density near the edge. Our results also hold if the Haar
unitary matrix is replaced by the Haar orthogonal matrix.

text: Recent discoveries have shown that, when two layers of van der Waals (vdW)
materials are superimposed with a relative twist angle between them, the electronic
properties of the coupled system can be dramatically altered. Here, we demonstrate
that a similar concept can be extended to the optics realm, particularly to propagating
phonon polaritons–hybrid light-matter interactions. To do this, we fabricate stacks
composed of two twisted slabs of a vdW crystal (α-MoO3) supporting anisotropic
phonon polaritons (PhPs), and image the propagation of the latter when launched
by localized sources. Our images reveal that, under a critical angle, the PhPs
isofrequency curve undergoes a topological transition, in which the propagation
of PhPs is strongly guided (canalization regime) along predetermined directions
without geometric spreading. These results demonstrate a new degree of freedom
(twist angle) for controlling the propagation of polaritons at the nanoscale with
potential for nanoimaging, (bio)-sensing, or heat management.

text: Mutations in NDUFS4, which encodes an accessory subunit of mitochondrial oxidative
phosphorylation (OXPHOS) complex I (CI), induce Leigh syndrome (LS). LS is a poorly
understood pediatric disorder featuring brain-specific anomalies and early death.
To study the LS pathomechanism, we here compared OXPHOS proteomes between various
Ndufs4−/− mouse tissues. Ndufs4−/− animals displayed significantly lower CI subunit
levels in brain/diaphragm relative to other tissues (liver/heart/kidney/skeletal
muscle), whereas other OXPHOS subunit levels were not reduced. Absence of NDUFS4
induced near complete absence of the NDUFA12 accessory subunit, a 50% reduction
in other CI subunit levels, and an increase in specific CI assembly factors. Among
the latter, NDUFAF2 was most highly increased. Regarding NDUFS4, NDUFA12 and NDUFAF2,
identical results were obtained in Ndufs4−/− mouse embryonic fibroblasts (MEFs)
and NDUFS4-mutated LS patient cells. Ndufs4−/− MEFs contained active CI in situ
but blue-native-PAGE highlighted that NDUFAF2 attached to an inactive CI subcomplex
(CI-830) and inactive assemblies of higher MW. In NDUFA12-mutated LS patient cells,
NDUFA12 absence did not reduce NDUFS4 levels but triggered NDUFAF2 association
to active CI. BN-PAGE revealed no such association in LS patient fibroblasts with
mutations in other CI subunit-encoding genes where NDUFAF2 was attached to CI-830
(NDUFS1, NDUFV1 mutation) or not detected (NDUFS7 mutation). Supported by enzymological
and CI in silico structural analysis, we conclude that absence of NDUFS4 induces
near complete absence of NDUFA12 but not vice versa, and that NDUFAF2 stabilizes
active CI in Ndufs4−/− mice and LS patient cells, perhaps in concert with mitochondrial
inner membrane lipids.

text: During embryonic and postnatal development, organs and tissues grow steadily
to achieve their final size at the end of puberty. However, little is known about
the cellular dynamics that mediate postnatal growth. By combining in vivo clonal
lineage tracing, proliferation kinetics, single-cell transcriptomics, andin vitro
micro-pattern experiments, we resolved the cellular dynamics taking place during
postnatal skin epidermis expansion. Our data revealed that harmonious growth is
engineered by a single population of developmental progenitors presenting a fixed
fate imbalance of self-renewing divisions with an ever-decreasing proliferation
rate. Single-cell RNA sequencing revealed that epidermal developmental progenitors
form a more uniform population compared with adult stem and progenitor cells.
Finally, we found that the spatial pattern of cell division orientation is dictated
locally by the underlying collagen fiber orientation. Our results uncover a simple
design principle of organ growth where progenitors and differentiated cells expand
in harmony with their surrounding tissues.

text: "We prove a lower bound for the free energy (per unit volume) of the two-dimensional
Bose gas in the thermodynamic limit. We show that the free energy at density \U0001D70C
and inverse temperature \U0001D6FD differs from the one of the noninteracting
system by the correction term \U0001D70B\U0001D70C\U0001D70C\U0001D6FD\U0001D6FD
. Here, is the scattering length of the interaction potential, and \U0001D6FD
is the inverse Berezinskii–Kosterlitz–Thouless critical temperature for superfluidity.
The result is valid in the dilute limit \U0001D70C and if \U0001D6FD\U0001D70C

text: Phonon polaritons—light coupled to lattice vibrations—in polar van der Waals
crystals are promising candidates for controlling the flow of energy on the nanoscale
due to their strong field confinement, anisotropic propagation and ultra-long
lifetime in the picosecond range1,2,3,4,5. However, the lack of tunability of
their narrow and material-specific spectral range—the Reststrahlen band—severely
limits their technological implementation. Here, we demonstrate that intercalation
of Na atoms in the van der Waals semiconductor α-V2O5 enables a broad spectral
shift of Reststrahlen bands, and that the phonon polaritons excited show ultra-low
losses (lifetime of 4 ± 1 ps), similar to phonon polaritons in a non-intercalated
crystal (lifetime of 6 ± 1 ps). We expect our intercalation method to be applicable
to other van der Waals crystals, opening the door for the use of phonon polaritons
in broad spectral bands in the mid-infrared domain.
