text: Coherent flows of self-propelled particles are characterized by vortices and
jets that sustain chaotic flows, referred to as active turbulence. Here, we reveal
a crossover between defect-free active turbulence and active turbulence laden
with topological defects. Interestingly, we show that concurrent to the crossover
from defect-free to defect-laden active turbulence is the restoration of the previously
broken SO(2) symmetry signaled by the fast decay of the two-point correlations.
By stability analyses of the topological charge density field, we provide theoretical
insights on the criterion for the crossover to the defect-laden active turbulent
state. Despite the distinct symmetry features between these two active turbulence
regimes, the flow fluctuations exhibit universal statistical scaling behaviors
at large scales, while the spectrum of polarity fluctuations decays exponentially
at small length scales compared to the active energy injection length. These findings
reveal a dynamical crossover between distinct spatiotemporal organization patterns
in polar active matter.

text: In this paper, we study the eigenvalues and eigenvectors of the spiked invariant
multiplicative models when the randomness is from Haar matrices. We establish
the limits of the outlier eigenvalues λˆi and the generalized components (⟨v,uˆi⟩
for any deterministic vector v) of the outlier eigenvectors uˆi with optimal convergence
rates. Moreover, we prove that the non-outlier eigenvalues stick with those of
the unspiked matrices and the non-outlier eigenvectors are delocalized. The results
also hold near the so-called BBP transition and for degenerate spikes. On one
hand, our results can be regarded as a refinement of the counterparts of [12]
under additional regularity conditions. On the other hand, they can be viewed
as an analog of [34] by replacing the random matrix with i.i.d. entries with Haar
random matrix.

text: "The Kirchhoff rod model describes the bending and twisting of slender elastic
rods in three dimensions, and has been widely studied to enable the prediction
of how a rod will deform, given its geometry and boundary conditions. In this
work, we study a number of inverse problems with the goal of computing the geometry
of a straight rod that will automatically deform to match a curved target shape
after attaching its endpoints to a support structure. Our solution lets us finely
control the static equilibrium state of a rod by varying the cross-sectional profiles
along its length.\r\nWe also show that the set of physically realizable equilibrium
states admits a concise geometric description in terms of linear line complexes,
which leads to very efficient computational design algorithms. Implemented in
an interactive software tool, they allow us to convert three-dimensional hand-drawn
spline curves to elastic rods, and give feedback about the feasibility and practicality
of a design in real time. We demonstrate the efficacy of our method by designing
and manufacturing several physical prototypes with applications to interior design
and soft robotics."

text: Tattoos are a highly popular medium, with both artistic and medical applications.
Although the mechanical process of tattoo application has evolved historically,
the results are reliant on the artisanal skill of the artist. This can be especially
challenging for some skin tones, or in cases where artists lack experience. We
provide the first systematic overview of tattooing as a computational fabrication
technique. We built an automated tattooing rig and a recipe for the creation of
silicone sheets mimicking realistic skin tones, which allowed us to create an
accurate model predicting tattoo appearance. This enables several exciting applications
including tattoo previewing, color retargeting, novel ink spectra optimization,
color-accurate prosthetics, and more.

text: "We revisit two basic Direct Simulation Monte Carlo Methods to model aggregation
kinetics and extend them for aggregation processes with collisional fragmentation
(shattering). We test the performance and accuracy of the extended methods and
compare their performance with efficient deterministic finite-difference method
applied to the same model. We validate the stochastic methods on the test problems
and apply them to verify the existence of oscillating regimes in the aggregation-fragmentation
kinetics recently detected in deterministic simulations. We confirm the emergence
of steady oscillations of densities in such systems and prove the stability of
the\r\noscillations with respect to fluctuations and noise."

text: In the class of strictly convex smooth boundaries each of which has no strip
around its boundary foliated by invariant curves, we prove that the Taylor coefficients
of the “normalized” Mather’s β-function are invariant under C∞-conjugacies. In
contrast, we prove that any two elliptic billiard maps are C0-conjugate near their
respective boundaries, and C∞-conjugate, near the boundary and away from a line
passing through the center of the underlying ellipse. We also prove that, if the
billiard maps corresponding to two ellipses are topologically conjugate, then
the two ellipses are similar.

text: ESCRT-III filaments are composite cytoskeletal polymers that can constrict
and cut cell membranes from the inside of the membrane neck. Membrane-bound ESCRT-III
filaments undergo a series of dramatic composition and geometry changes in the
presence of an ATP-consuming Vps4 enzyme, which causes stepwise changes in the
membrane morphology. We set out to understand the physical mechanisms involved
in translating the changes in ESCRT-III polymer composition into membrane deformation.
We have built a coarse-grained model in which ESCRT-III polymers of different
geometries and mechanical properties are allowed to copolymerise and bind to a
deformable membrane. By modelling ATP-driven stepwise depolymerisation of specific
polymers, we identify mechanical regimes in which changes in filament composition
trigger the associated membrane transition from a flat to a buckled state, and
then to a tubule state that eventually undergoes scission to release a small cargo-loaded
vesicle. We then characterise how the location and kinetics of polymer loss affects
the extent of membrane deformation and the efficiency of membrane neck scission.
Our results identify the near-minimal mechanical conditions for the operation
of shape-shifting composite polymers that sever membrane necks.

text: Models of transcriptional regulation that assume equilibrium binding of transcription
factors have been less successful at predicting gene expression from sequence
in eukaryotes than in bacteria. This could be due to the non-equilibrium nature
of eukaryotic regulation. Unfortunately, the space of possible non-equilibrium
mechanisms is vast and predominantly uninteresting. The key question is therefore
how this space can be navigated efficiently, to focus on mechanisms and models
that are biologically relevant. In this review, we advocate for the normative
role of theory—theory that prescribes rather than just describes—in providing
such a focus. Theory should expand its remit beyond inferring mechanistic models
from data, towards identifying non-equilibrium gene regulatory schemes that may
have been evolutionarily selected, despite their energy consumption, because they
are precise, reliable, fast, or otherwise outperform regulation at equilibrium.
We illustrate our reasoning by toy examples for which we provide simulation code.

text: In this paper we consider the stochastic primitive equation for geophysical
flows subject to transport noise and turbulent pressure. Admitting very rough
noise terms, the global existence and uniqueness of solutions to this stochastic
partial differential equation are proven using stochastic maximal L² regularity,
the theory of critical spaces for stochastic evolution equations, and global a
priori bounds. Compared to other results in this direction, we do not need any
smallness assumption on the transport noise which acts directly on the velocity
field and we also allow rougher noise terms. The adaptation to Stratonovich type
noise and, more generally, to variable viscosity and/or conductivity are discussed
as well.

text: We report frictional drag reduction and a complete flow relaminarization of
elastic turbulence (ET) at vanishing inertia in a viscoelastic channel flow past
an obstacle. We show that the intensity of the observed elastic waves and wall-normal
vorticity correlate well with the measured drag above the onset of ET. Moreover,
we find that the elastic wave frequency grows with the Weissenberg number, and
at sufficiently high frequency it causes a decay of the elastic waves, resulting
in ET attenuation and drag reduction. Thus, this allows us to substantiate a physical
mechanism, involving the interaction of elastic waves with wall-normal vorticity
fluctuations, leading to the drag reduction and relaminarization phenomena at
low Reynolds number.

text: 'In repeated interactions, players can use strategies that respond to the
outcome of previous rounds. Much of the existing literature on direct reciprocity
assumes that all competing individuals use the same strategy space. Here, we study
both learning and evolutionary dynamics of players that differ in the strategy
space they explore. We focus on the infinitely repeated donation game and compare
three natural strategy spaces: memory-1 strategies, which consider the last moves
of both players, reactive strategies, which respond to the last move of the co-player,
and unconditional strategies. These three strategy spaces differ in the memory
capacity that is needed. We compute the long term average payoff that is achieved
in a pairwise learning process. We find that smaller strategy spaces can dominate
larger ones. For weak selection, unconditional players dominate both reactive
and memory-1 players. For intermediate selection, reactive players dominate memory-1
players. Only for strong selection and low cost-to-benefit ratio, memory-1 players
dominate the others. We observe that the supergame between strategy spaces can
be a social dilemma: maximum payoff is achieved if both players explore a larger
strategy space, but smaller strategy spaces dominate.'

text: 'We present a faster symbolic algorithm for the following central problem
in probabilistic verification: Compute the maximal end-component (MEC) decomposition
of Markov decision processes (MDPs). This problem generalizes the SCC decomposition
problem of graphs and closed recurrent sets of Markov chains. The model of symbolic
algorithms is widely used in formal verification and model-checking, where access
to the input model is restricted to only symbolic operations (e.g., basic set
operations and computation of one-step neighborhood). For an input MDP with n vertices
and m edges, the classical symbolic algorithm from the 1990s for the MEC decomposition
requires O(n2) symbolic operations and O(1) symbolic space. The only other
symbolic algorithm for the MEC decomposition requires O(nm−−√) symbolic operations
and O(m−−√) symbolic space. A main open question is whether the worst-case O(n2) bound
for symbolic operations can be beaten. We present a symbolic algorithm that requires O˜(n1.5) symbolic
operations and O˜(n−−√) symbolic space. Moreover, the parametrization of our
algorithm provides a trade-off between symbolic operations and symbolic space:
for all 0<ϵ≤1/2 the symbolic algorithm requires O˜(n2−ϵ) symbolic operations
and O˜(nϵ) symbolic space ( O˜ hides poly-logarithmic factors). Using our techniques
we present faster algorithms for computing the almost-sure winning regions of ω
-regular objectives for MDPs. We consider the canonical parity objectives for ω
-regular objectives, and for parity objectives with d -priorities we present
an algorithm that computes the almost-sure winning region with O˜(n2−ϵ) symbolic
operations and O˜(nϵ) symbolic space, for all 0<ϵ≤1/2 .'

text: Elastic bending of initially flat slender elements allows the realization
and economic fabrication of intriguing curved shapes. In this work, we derive
an intuitive but rigorous geometric characterization of the design space of plane
elastic rods with variable stiffness. It enables designers to determine which
shapes are physically viable with active bending by visual inspection alone. Building
on these insights, we propose a method for efficiently designing the geometry
of a flat elastic rod that realizes a target equilibrium curve, which only requires
solving a linear program. We implement this method in an interactive computational
design tool that gives feedback about the feasibility of a design, and computes
the geometry of the structural elements necessary to realize it within an instant.
The tool also offers an iterative optimization routine that improves the fabricability
of a model while modifying it as little as possible. In addition, we use our geometric
characterization to derive an algorithm for analyzing and recovering the stability
of elastic curves that would otherwise snap out of their unstable equilibrium
shapes by buckling. We show the efficacy of our approach by designing and manufacturing
several physical models that are assembled from flat elements.

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: "Fabrication of curved shells plays an important role in modern design, industry,
and science. Among their remarkable properties are, for example, aesthetics of
organic shapes, ability to evenly distribute loads, or efficient flow separation.
They find applications across vast length scales ranging from sky-scraper architecture
to microscopic devices. But, at\r\nthe same time, the design of curved shells
and their manufacturing process pose a variety of challenges. In this thesis,
they are addressed from several perspectives. In particular, this thesis presents
approaches based on the transformation of initially flat sheets into the target
curved surfaces. This involves problems of interactive design of shells with nontrivial
mechanical constraints, inverse design of complex structural materials, and data-driven
modeling of delicate and time-dependent physical properties. At the same time,
two newly-developed self-morphing mechanisms targeting flat-to-curved transformation
are presented.\r\nIn architecture, doubly curved surfaces can be realized as cold
bent glass panelizations. Originally flat glass panels are bent into frames and
remain stressed. This is a cost-efficient fabrication approach compared to hot
bending, when glass panels are shaped plastically. However such constructions
are prone to breaking during bending, and it is highly\r\nnontrivial to navigate
the design space, keeping the panels fabricable and aesthetically pleasing at
the same time. We introduce an interactive design system for cold bent glass façades,
while previously even offline optimization for such scenarios has not been sufficiently
developed. Our method is based on a deep learning approach providing quick\r\nand
high precision estimation of glass panel shape and stress while handling the shape\r\nmultimodality.\r\nFabrication
of smaller objects of scales below 1 m, can also greatly benefit from shaping
originally flat sheets. In this respect, we designed new self-morphing shell mechanisms
transforming from an initial flat state to a doubly curved state with high precision
and detail. Our so-called CurveUps demonstrate the encodement of the geometric
information\r\ninto the shell. Furthermore, we explored the frontiers of programmable
materials and showed how temporal information can additionally be encoded into
a flat shell. This allows prescribing deformation sequences for doubly curved
surfaces and, thus, facilitates self-collision avoidance enabling complex shapes
and functionalities otherwise impossible.\r\nBoth of these methods include inverse
design tools keeping the user in the design loop."
