text: "Substrate induces mechanical strain on perovskite devices, which can result
in alterations to its lattice dynamics and thermal transport. Herein, we have
performed a theoretical investigation on the anharmonic lattice dynamics and thermal
property of perovskite Rb2SnBr6 and Cs2SnBr6 under strains using perturbation
theory up to the fourth-order terms and the unified thermal transport theory.
We demonstrate a pronounced hardening of low-frequency optical phonons as temperature
increases, indicating strong lattice anharmonicity and the necessity of adopting
temperature-dependent interatomic force constants in the lattice thermal conductivity
(\r\nκL) calculations. It is found that the low-lying optical phonon modes of
Rb2SnBr6 are extremely soft and their phonon energies are almost strain independent,
which ultimately lead to a lower \r\nκL and a weaker strain dependence than Cs2SnBr6.
We further reveal that the strain dependence of these phonon modes in the A2XB6-type
perovskites weakens as their ibrational frequency decreases. This study deepens
the understanding of lattice thermal transport in perovskites A2XB6 and provides
a perspective on the selection of materials that meet the expected thermal behaviors
in practical applications."

text: Atom-based quantum simulators have had many successes in tackling challenging
quantum many-body problems, owing to the precise and dynamical control that they
provide over the systems' parameters. They are, however, often optimized to address
a specific type of problem. Here, we present the design and implementation of
a 6Li-based quantum gas platform that provides wide-ranging capabilities and is
able to address a variety of quantum many-body problems. Our two-chamber architecture
relies on a robust combination of gray molasses and optical transport from a laser-cooling
chamber to a glass cell with excellent optical access. There, we first create
unitary Fermi superfluids in a three-dimensional axially symmetric harmonic trap
and characterize them using in situ thermometry, reaching temperatures below 20
nK. This allows us to enter the deep superfluid regime with samples of extreme
diluteness, where the interparticle spacing is sufficiently large for direct single-atom
imaging. Second, we generate optical lattice potentials with triangular and honeycomb
geometry in which we study diffraction of molecular Bose-Einstein condensates,
and show how going beyond the Kapitza-Dirac regime allows us to unambiguously
distinguish between the two geometries. With the ability to probe quantum many-body
physics in both discrete and continuous space, and its suitability for bulk and
single-atom imaging, our setup represents an important step towards achieving
a wide-scope quantum simulator.

text: 'Direct reciprocity is a powerful mechanism for cooperation in social dilemmas.
The very logic of reciprocity, however, seems to require that individuals are
symmetric, and that everyone has the same means to influence each others’ payoffs.
Yet in many applications, individuals are asymmetric. Herein, we study the effect
of asymmetry in linear public good games. Individuals may differ in their endowments
(their ability to contribute to a public good) and in their productivities (how
effective their contributions are). Given the individuals’ productivities, we
ask which allocation of endowments is optimal for cooperation. To this end, we
consider two notions of optimality. The first notion focuses on the resilience
of cooperation. The respective endowment distribution ensures that full cooperation
is feasible even under the most adverse conditions. The second notion focuses
on efficiency. The corresponding endowment distribution maximizes group welfare.
Using analytical methods, we fully characterize these two endowment distributions.
This analysis reveals that both optimality notions favor some endowment inequality:
More productive players ought to get higher endowments. Yet the two notions disagree
on how unequal endowments are supposed to be. A focus on resilience results in
less inequality. With additional simulations, we show that the optimal endowment
allocation needs to account for both the resilience and the efficiency of cooperation.'

text: We present a dynamic data structure for maintaining the persistent homology
of a time series of real numbers. The data structure supports local operations,
including the insertion and deletion of an item and the cutting and concatenating
of lists, each in time O(log n + k), in which n counts the critical items and
k the changes in the augmented persistence diagram. To achieve this, we design
a tailor-made tree structure with an unconventional representation, referred to
as banana tree, which may be useful in its own right.

text: "Point sets, geometric networks, and arrangements of hyperplanes are fundamental
objects in\r\ndiscrete geometry that have captivated mathematicians for centuries,
if not millennia. This\r\nthesis seeks to cast new light on these structures by
illustrating specific instances where a\r\ntopological perspective, specifically
through discrete Morse theory and persistent homology,\r\nprovides valuable insights.\r\n\r\nAt
first glance, the topology of these geometric objects might seem uneventful: point
sets\r\nessentially lack of topology, arrangements of hyperplanes are a decomposition
of Rd, which\r\nis a contractible space, and the topology of a network primarily
involves the enumeration\r\nof connected components and cycles within the network.
However, beneath this apparent\r\nsimplicity, there lies an array of intriguing
structures, a small subset of which will be uncovered\r\nin this thesis.\r\n\r\nFocused
on three case studies, each addressing one of the mentioned objects, this work\r\nwill
showcase connections that intertwine topology with diverse fields such as combinatorial\r\ngeometry,
algorithms and data structures, and emerging applications like spatial biology.\r\n\r\n"

text: Global storm-resolving models (GSRMs) use strongly refined horizontal grids
compared with the climate models typically used in the Coupled Model Intercomparison
Project (CMIP) but employ comparable vertical grid spacings. Here, we study how
changes in the vertical grid spacing and adjustments to the integration time step
affect the basic climate quantities simulated by the ICON-Sapphire atmospheric
GSRM. Simulations are performed over a 45 d period for five different vertical
grids with between 55 and 540 vertical layers and maximum tropospheric vertical
grid spacings of between 800 and 50 m, respectively. The effects of changes in
the vertical grid spacing are compared with the effects of reducing the horizontal
grid spacing from 5 to 2.5 km. For most of the quantities considered, halving
the vertical grid spacing has a smaller effect than halving the horizontal grid
spacing, but it is not negligible. Each halving of the vertical grid spacing,
along with the necessary reductions in time step length, increases cloud liquid
water by about 7 %, compared with an approximate 16 % decrease for halving the
horizontal grid spacing. The effect is due to both the vertical grid refinement
and the time step reduction. There is no tendency toward convergence in the range
of grid spacings tested here. The cloud ice amount also increases with a refinement
in the vertical grid, but it is hardly affected by the time step length and does
show a tendency to converge. While the effect on shortwave radiation is globally
dominated by the altered reflection due to the change in the cloud liquid water
content, the effect on longwave radiation is more difficult to interpret because
changes in the cloud ice concentration and cloud fraction are anticorrelated in
some regions. The simulations show that using a maximum tropospheric vertical
grid spacing larger than 400 m would increase the truncation error strongly. Computing
time investments in a further vertical grid refinement can affect the truncation
errors of GSRMs similarly to comparable investments in horizontal refinement,
because halving the vertical grid spacing is generally cheaper than halving the
horizontal grid spacing. However, convergence of boundary layer cloud properties
cannot be expected, even for the smallest maximum tropospheric grid spacing of
50 m used in this study.

text: The paper is devoted to the analysis of the global well-posedness and the
interior regularity of the 2D Navier–Stokes equations with inhomogeneous stochastic
boundary conditions. The noise, white in time and coloured in space, can be interpreted
as the physical law describing the driving mechanism on the atmosphere–ocean interface,
i.e. as a balance of the shear stress of the ocean and the horizontal wind force.

text: Speciation is a key evolutionary process that is not yet fully understood.
Combining population genomic and ecological data from multiple diverging pairs
of marine snails (Littorina) supports the search for speciation mechanisms. Placing
pairs on a one-dimensional speciation continuum, from undifferentiated populations
to species, obscured the complexity of speciation. Adding multiple axes helped
to describe either speciation routes or reproductive isolation in the snails.
Divergent ecological selection repeatedly generated barriers between ecotypes,
but appeared less important in completing speciation while genetic incompatibilities
played a key role. Chromosomal inversions contributed to genomic barriers, but
with variable impact. A multidimensional (hypercube) approach supported framing
of questions and identification of knowledge gaps and can be useful to understand
speciation in many other systems.

text: As a key liquid organic hydrogen carrier, investigating the decomposition
of formic acid (HCOOH) on the Pd (1 1 1) transition metal surface is imperative
for harnessing hydrogen energy. Despite a multitude of studies, the major mechanisms
and key intermediates involved in the dehydrogenation process of formic acid remain
a great topic of debate due to ambiguous adsorbate interactions. In this research,
we develop an advanced microkinetic model based on first-principles calculations,
accounting for adsorbate–adsorbate interactions. Our study unveils a comprehensive
mechanism for the Pd (1 1 1) surface, highlighting the significance of coverage
effects in formic acid dehydrogenation. Our findings unequivocally demonstrate
that H coverage on the Pd (1 1 1) surface renders formic acid more susceptible
to decompose into H2 and CO2 through COOH intermediates. Consistent with experimental
results, the selectivity of H2 in the decomposition of formic acid on the Pd (1
1 1) surface approaches 100 %. Considering the influence of H coverage, our kinetic
analysis aligns perfectly with experimental values at a temperature of 373 K.

text: Water is known to play an important role in collagen self-assembly, but it
is still largely unclear how water–collagen interactions influence the assembly
process and determine the fibril network properties. Here, we use the H2O/D2O
isotope effect on the hydrogen-bond strength in water to investigate the role
of hydration in collagen self-assembly. We dissolve collagen in H2O and D2O and
compare the growth kinetics and the structure of the collagen assemblies formed
in these water isotopomers. Surprisingly, collagen assembly occurs ten times faster
in D2O than in H2O, and collagen in D2O self-assembles into much thinner fibrils,
that form a more inhomogeneous and softer network, with a fourfold reduction in
elastic modulus when compared to H2O. Combining spectroscopic measurements with
atomistic simulations, we show that collagen in D2O is less hydrated than in H2O.
This partial dehydration lowers the enthalpic penalty for water removal and reorganization
at the collagen–water interface, increasing the self-assembly rate and the number
of nucleation centers, leading to thinner fibrils and a softer network. Coarse-grained
simulations show that the acceleration in the initial nucleation rate can be reproduced
by the enhancement of electrostatic interactions. These results show that water
acts as a mediator between collagen monomers, by modulating their interactions
so as to optimize the assembly process and, thus, the final network properties.
We believe that isotopically modulating the hydration of proteins can be a valuable
method to investigate the role of water in protein structural dynamics and protein
self-assembly.

this synapse is accessible to direct presynaptic recording, allowing a rigorous
investigation of the biophysical mechanisms of synaptic transmission and plasticity.
Furthermore, because of its placement in the very center of the hippocampal memory
circuit, this synapse seems to be critically involved in several higher network
functions, such as learning, memory, pattern separation, and pattern completion.
Recent work based on new technologies in both nanoanatomy and nanophysiology,
including presynaptic patch-clamp recording, paired recording, super-resolution
light microscopy, and freeze-fracture and “flash-and-freeze” electron microscopy,
has provided new insights into the structure, biophysics, and network function
of this intriguing synapse. This brings us one step closer to answering a fundamental
question in neuroscience: how basic synaptic properties shape higher network computations.'

text: Cell division in all domains of life requires the orchestration of many proteins,
but in Archaea most of the machinery remains poorly characterized. Here we investigate
the FtsZ-based cell division mechanism in Haloferax volcanii and find proteins
containing photosynthetic reaction centre (PRC) barrel domains that play an essential
role in archaeal cell division. We rename these proteins cell division protein
B 1 (CdpB1) and CdpB2. Depletions and deletions in their respective genes cause
severe cell division defects, generating drastically enlarged cells. Fluorescence
microscopy of tagged FtsZ1, FtsZ2 and SepF in CdpB1 and CdpB2 mutant strains revealed
an unusually disordered divisome that is not organized into a distinct ring-like
structure. Biochemical analysis shows that SepF forms a tripartite complex with
CdpB1/2 and crystal structures suggest that these two proteins might form filaments,
possibly aligning SepF and the FtsZ2 ring during cell division. Overall our results
indicate that PRC-domain proteins play essential roles in FtsZ-based cell division
in Archaea.

text: In this paper we consider an SPDE where the leading term is a second order
operator with periodic boundary conditions, coefficients which are measurable
in (t,ω) , and Hölder continuous in space. Assuming stochastic parabolicity conditions,
we prove Lp((0,T)×Ω,tκdt;Hσ,q(Td)) -estimates. The main novelty is that we do
not require p=q . Moreover, we allow arbitrary σ∈R and weights in time. Such
mixed regularity estimates play a crucial role in applications to nonlinear SPDEs
which is clear from our previous work. To prove our main results we develop a
general perturbation theory for SPDEs. Moreover, we prove a new result on pointwise
multiplication in spaces with fractional smoothness.

text: Quantum computers are increasing in size and quality but are still very noisy.
Error mitigation extends the size of the quantum circuits that noisy devices can
meaningfully execute. However, state-of-the-art error mitigation methods are hard
to implement and the limited qubit connectivity in superconducting qubit devices
restricts most applications to the hardware's native topology. Here we show a
quantum approximate optimization algorithm (QAOA) on nonplanar random regular
graphs with up to 40 nodes enabled by a machine learning-based error mitigation.
We use a swap network with careful decision-variable-to-qubit mapping and a feed-forward
neural network to optimize a depth-two QAOA on up to 40 qubits. We observe a meaningful
parameter optimization for the largest graph which requires running quantum circuits
with 958 two-qubit gates. Our paper emphasizes the need to mitigate samples, and
not only expectation values, in quantum approximate optimization. These results
are a step towards executing quantum approximate optimization at a scale that
is not classically simulable. Reaching such system sizes is key to properly understanding
the true potential of heuristic algorithms like QAOA.

text: The extracellular matrix (ECM) serves as a scaffold for cells and plays an
essential role in regulating numerous cellular processes, including cell migration
and proliferation. Due to limitations in specimen preparation for conventional
room-temperature electron microscopy, we lack structural knowledge on how ECM
components are secreted, remodeled, and interact with surrounding cells. We have
developed a 3D-ECM platform compatible with sample thinning by cryo-focused ion
beam milling, the lift-out extraction procedure, and cryo-electron tomography.
Our workflow implements cell-derived matrices (CDMs) grown on EM grids, resulting
in a versatile tool closely mimicking ECM environments. This allows us to visualize
ECM for the first time in its hydrated, native context. Our data reveal an intricate
network of extracellular fibers, their positioning relative to matrix-secreting
cells, and previously unresolved structural entities. Our workflow and results
add to the structural atlas of the ECM, providing novel insights into its secretion
and assembly.

text: For some k∈Z≥0∪{∞}, we call a linear forest k-bounded if each of its components
has at most k edges. We will say a (k,ℓ)-bounded linear forest decomposition of
a graph G is a partition of E(G) into the edge sets of two linear forests Fk,Fℓ
where Fk is k-bounded and Fℓ is ℓ-bounded. We show that the problem of deciding
whether a given graph has such a decomposition is NP-complete if both k and ℓ
are at least 2, NP-complete if k≥9 and ℓ=1, and is in P for (k,ℓ)=(2,1). Before
this, the only known NP-complete cases were the (2,2) and (3,3) cases. Our hardness
result answers a question of Bermond et al. from 1984. We also show that planar
graphs of girth at least nine decompose into a linear forest and a matching, which
in particular is stronger than 3-edge-colouring such graphs.

text: Primary implant stability, which refers to the stability of the implant during
the initial healing period is a crucial factor in determining the long-term success
of the implant and lays the foundation for secondary implant stability achieved
through osseointegration. Factors affecting primary stability include implant
design, surgical technique, and patient-specific factors like bone quality and
morphology. In vivo, the cyclic nature of anatomical loading puts osteosynthesis
locking screws under dynamic loads, which can lead to the formation of micro cracks
and defects that slowly degrade the mechanical connection between the bone and
screw, thus compromising the initial stability and secondary stability of the
implant. Monotonic quasi-static loading used for testing the holding capacity
of implanted screws is not well suited to capture this behavior since it cannot
capture the progressive deterioration of peri‑implant bone at small displacements.
In order to address this issue, this study aims to determine a critical point
of loss of primary implant stability in osteosynthesis locking screws under cyclic
overloading by investigating the evolution of damage, dissipated energy, and permanent
deformation. A custom-made test setup was used to test implanted 2.5 mm locking
screws under cyclic overloading test. For each loading cycle, maximum forces and
displacement were recorded as well as initial and final cycle displacements and
used to calculate damage and energy dissipation evolution. The results of this
study demonstrate that for axial, shear, and mixed loading significant damage
and energy dissipation can be observed at approximately 20 % of the failure force.
Additionally, at this load level, permanent deformations on the screw-bone interface
were found to be in the range of 50 to 150 mm which promotes osseointegration
and secondary implant stability. This research can assist surgeons in making informed
preoperative decisions by providing a better understanding of the critical point
of loss of primary implant stability, thus improving the long-term success of
the implant and overall patient satisfaction.
