text: Tropisms, growth responses to environmental stimuli such as light or gravity,
are spectacular examples of adaptive plant development. The plant hormone auxin
serves as a major coordinative signal. The PIN auxin exporters, through their
dynamic polar subcellular localizations, redirect auxin fluxes in response to
environmental stimuli and the resulting auxin gradients across organs underly
differential cell elongation and bending. In this review, we discuss recent advances
concerning regulations of PIN polarity during tropisms, focusing on PIN phosphorylation
and trafficking. We also cover how environmental cues regulate PIN actions during
tropisms, and a crucial role of auxin feedback on PIN polarity during bending
termination. Finally, the interactions between different tropisms are reviewed
to understand plant adaptive growth in the natural environment.

text: To overcome nitrogen deficiency, legume roots establish symbiotic interactions
with nitrogen-fixing rhizobia that is fostered in specialized organs (nodules).
Similar to other organs, nodule formation is determined by a local maximum of
the phytohormone auxin at the primordium site. However, how auxin regulates nodule
development remains poorly understood. Here, we found that in soybean, (Glycine
max), dynamic auxin transport driven by PIN-FORMED (PIN) transporter GmPIN1 is
involved in nodule primordium formation. GmPIN1 was specifically expressed in
nodule primordium cells and GmPIN1 was polarly localized in these cells. Two nodulation
regulators, (iso)flavonoids trigger expanded distribution of GmPIN1b to root cortical
cells, and cytokinin rearranges GmPIN1b polarity. Gmpin1abc triple mutants generated
with CRISPR-Cas9 showed impaired establishment of auxin maxima in nodule meristems
and aberrant divisions in the nodule primordium cells. Moreover, overexpression
of GmPIN1 suppressed nodule primordium initiation. GmPIN9d, an ortholog of Arabidopsis
thaliana PIN2, acts together with GmPIN1 later in nodule development to acropetally
transport auxin in vascular bundles, fine-tuning the auxin supply for nodule enlargement.
Our findings reveal how PIN-dependent auxin transport modulates different aspects
of soybean nodule development and suggest that establishment of auxin gradient
is a prerequisite for the proper interaction between legumes and rhizobia.

text: The set of known stable phases of water may not be complete, and some of the
phase boundaries between them are fuzzy. Starting from liquid water and a comprehensive
set of 50 ice structures, we compute the phase diagram at three hybrid density-functional-theory
levels of approximation, accounting for thermal and nuclear fluctuations as well
as proton disorder. Such calculations are only made tractable because we combine
machine-learning methods and advanced free-energy techniques. The computed phase
diagram is in qualitative agreement with experiment, particularly at pressures ≲ 8000
bar, and the discrepancy in chemical potential is comparable with the subtle uncertainties
introduced by proton disorder and the spread between the three hybrid functionals.
None of the hypothetical ice phases considered is thermodynamically stable in
our calculations, suggesting the completeness of the experimental water phase
diagram in the region considered. Our work demonstrates the feasibility of predicting
the phase diagram of a polymorphic system from first principles and provides a
thermodynamic way of testing the limits of quantum-mechanical calculations.

text: We introduce a new graph problem, the token dropping game, and we show how
to solve it efficiently in a distributed setting. We use the token dropping game
as a tool to design an efficient distributed algorithm for stable orientations
and more generally for locally optimal semi-matchings. The prior work by Czygrinow
et al. (DISC 2012) finds a stable orientation in O(Δ^5) rounds in graphs of maximum
degree Δ, while we improve it to O(Δ^4) and also prove a lower bound of Ω(Δ).
For the more general problem of locally optimal semi-matchings, the prior upper
bound is O(S^5) and our new algorithm runs in O(C · S^4) rounds, which is an improvement
for C = o(S); here C and S are the maximum degrees of customers and servers, respectively.

text: The relative motion of three impenetrable particles on a ring, in our case
two identical fermions and one impurity, is isomorphic to a triangular quantum
billiard. Depending on the ratio κ of the impurity and fermion masses, the billiards
can be integrable or non-integrable (also referred to in the main text as chaotic).
To set the stage, we first investigate the energy level distributions of the billiards
as a function of 1/κ ∈ [0, 1] and find no evidence of integrable cases beyond
the limiting values 1/κ = 1 and 1/κ = 0. Then, we use machine learning tools to
analyze properties of probability distributions of individual quantum states.
We find that convolutional neural networks can correctly classify integrable and
non-integrable states. The decisive features of the wave functions are the normalization
and a large number of zero elements, corresponding to the existence of a nodal
line. The network achieves typical accuracies of 97%, suggesting that machine
learning tools can be used to analyze and classify the morphology of probability
densities obtained in theory or experiment.

text: Inhibition or targeted deletion of histone deacetylase 3 (HDAC3) is neuroprotective
in a variety neurodegenerative conditions, including retinal ganglion cells (RGCs)
after acute optic nerve damage. Consistent with this, induced HDAC3 expression
in cultured cells shows selective toxicity to neurons. Despite an established
role for HDAC3 in neuronal pathology, little is known regarding the mechanism
of this pathology.

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: 'Markov chains are the de facto finite-state model for stochastic dynamical
systems, and Markov decision processes (MDPs) extend Markov chains by incorporating
non-deterministic behaviors. Given an MDP and rewards on states, a classical optimization
criterion is the maximal expected total reward where the MDP stops after T steps,
which can be computed by a simple dynamic programming algorithm. We consider a
natural generalization of the problem where the stopping times can be chosen according
to a probability distribution, such that the expected stopping time is T, to optimize
the expected total reward. Quite surprisingly we establish inter-reducibility
of the expected stopping-time problem for Markov chains with the Positivity problem
(which is related to the well-known Skolem problem), for which establishing either
decidability or undecidability would be a major breakthrough. Given the hardness
of the exact problem, we consider the approximate version of the problem: we show
that it can be solved in exponential time for Markov chains and in exponential
space for MDPs.'

text: We study systems of nonlinear partial differential equations of parabolic
type, in which the elliptic operator is replaced by the first-order divergence
operator acting on a flux function, which is related to the spatial gradient of
the unknown through an additional implicit equation. This setting, broad enough
in terms of applications, significantly expands the paradigm of nonlinear parabolic
problems. Formulating four conditions concerning the form of the implicit equation,
we first show that these conditions describe a maximal monotone p-coercive graph.
We then establish the global-in-time and large-data existence of a (weak) solution
and its uniqueness. To this end, we adopt and significantly generalize Minty’s
method of monotone mappings. A unified theory, containing several novel tools,
is developed in a way to be tractable from the point of view of numerical approximations.

text: The present thesis is concerned with the derivation of weak-strong uniqueness
principles for curvature driven interface evolution problems not satisfying a
comparison principle. The specific examples being treated are two-phase Navier-Stokes
flow with surface tension, modeling the evolution of two incompressible, viscous
and immiscible fluids separated by a sharp interface, and multiphase mean curvature
flow, which serves as an idealized model for the motion of grain boundaries in
an annealing polycrystalline material. Our main results - obtained in joint works
with Julian Fischer, Tim Laux and Theresa M. Simon - state that prior to the formation
of geometric singularities due to topology changes, the weak solution concept
of Abels (Interfaces Free Bound. 9, 2007) to two-phase Navier-Stokes flow with
surface tension and the weak solution concept of Laux and Otto (Calc. Var. Partial
Differential Equations 55, 2016) to multiphase mean curvature flow (for networks
in R^2 or double bubbles in R^3) represents the unique solution to these interface
evolution problems within the class of classical solutions, respectively. To the
best of the author's knowledge, for interface evolution problems not admitting
a geometric comparison principle the derivation of a weak-strong uniqueness principle
represented an open problem, so that the works contained in the present thesis
constitute the first positive results in this direction. The key ingredient of
our approach consists of the introduction of a novel concept of relative entropies
for a class of curvature driven interface evolution problems, for which the associated
energy contains an interfacial contribution being proportional to the surface
area of the evolving (network of) interface(s). The interfacial part of the relative
entropy gives sufficient control on the interface error between a weak and a classical
solution, and its time evolution can be computed, at least in principle, for any
energy dissipating weak solution concept. A resulting stability estimate for the
relative entropy essentially entails the above mentioned weak-strong uniqueness
principles. The present thesis contains a detailed introduction to our relative
entropy approach, which in particular highlights potential applications to other
problems in curvature driven interface evolution not treated in this thesis.

text: We propose a new weak solution concept for (two-phase) mean curvature flow
which enjoys both (unconditional) existence and (weak-strong) uniqueness properties.
These solutions are evolving varifolds, just as in Brakke's formulation, but are
coupled to the phase volumes by a simple transport equation. First, we show that,
in the exact same setup as in Ilmanen's proof [J. Differential Geom. 38, 417-461,
(1993)], any limit point of solutions to the Allen-Cahn equation is a varifold
solution in our sense. Second, we prove that any calibrated flow in the sense
of Fischer et al. [arXiv:2003.05478] - and hence any classical solution to mean
curvature flow - is unique in the class of our new varifold solutions. This is
in sharp contrast to the case of Brakke flows, which a priori may disappear at
any given time and are therefore fatally non-unique. Finally, we propose an extension
of the solution concept to the multi-phase case which is at least guaranteed to
satisfy a weak-strong uniqueness principle.

text: We derive a weak-strong uniqueness principle for BV solutions to multiphase
mean curvature flow of triple line clusters in three dimensions. Our proof is
based on the explicit construction of a gradient-flow calibration in the sense
of the recent work of Fischer et al. [arXiv:2003.05478] for any such cluster.
This extends the two-dimensional construction to the three-dimensional case of
surfaces meeting along triple junctions.

text: "Auxin plays a dual role in growth regulation and, depending on the tissue
and concentration of the hormone, it can either promote or inhibit division and
expansion processes in plants. Recent studies have revealed that, beyond transcriptional
reprogramming, alternative auxincontrolled mechanisms regulate root growth. Here,
we explored the impact of different concentrations of the synthetic auxin NAA
that establish growth-promoting and -repressing conditions on the root tip proteome
and phosphoproteome, generating a unique resource. From the phosphoproteome data,
we pinpointed (novel) growth regulators, such as the RALF34-THE1 module. Our results,
together with previously published studies, suggest that auxin, H+-ATPases, cell
wall modifications and cell wall sensing receptor-like kinases are tightly embedded
in a pathway regulating cell elongation. Furthermore, our study assigned a novel
role to MKK2 as a regulator of primary root growth and a (potential) regulator
of auxin biosynthesis and signalling, and suggests the importance of the MKK2\r\nThr31
phosphorylation site for growth regulation in the Arabidopsis root tip."

text: We study the temporal dissipation of variance and relative entropy for ergodic
Markov Chains in continuous time, and compute explicitly the corresponding dissipation
rates. These are identified, as is well known, in the case of the variance in
terms of an appropriate Hilbertian norm; and in the case of the relative entropy,
in terms of a Dirichlet form which morphs into a version of the familiar Fisher
information under conditions of detailed balance. Here we obtain trajectorial
versions of these results, valid along almost every path of the random motion
and most transparent in the backwards direction of time. Martingale arguments
and time reversal play crucial roles, as in the recent work of Karatzas, Schachermayer
and Tschiderer for conservative diffusions. Extensions are developed to general
“convex divergences” and to countable state-spaces. The steepest descent and gradient
flow properties for the variance, the relative entropy, and appropriate generalizations,
are studied along with their respective geometries under conditions of detailed
balance, leading to a very direct proof for the HWI inequality of Otto and Villani
in the present context.

text: In this paper, we introduce a random environment for the exclusion process
in obtained by assigning a maximal occupancy to each site. This maximal occupancy
is allowed to randomly vary among sites, and partial exclusion occurs. Under the
assumption of ergodicity under translation and uniform ellipticity of the environment,
we derive a quenched hydrodynamic limit in path space by strengthening the mild
solution approach initiated in Nagy (2002) and Faggionato (2007). To this purpose,
we prove, employing the technology developed for the random conductance model,
a homogenization result in the form of an arbitrary starting point quenched invariance
principle for a single particle in the same environment, which is a result of
independent interest. The self-duality property of the partial exclusion process
allows us to transfer this homogenization result to the particle system and, then,
apply the tightness criterion in Redig et al. (2020).

text: Ferromagnetism is most common in transition metal compounds but may also arise
in low-density two-dimensional electron systems, with signatures observed in silicon,
III-V semiconductor systems, and graphene moiré heterostructures. Here we show
that gate-tuned van Hove singularities in rhombohedral trilayer graphene drive
the spontaneous ferromagnetic polarization of the electron system into one or
more spin- and valley flavors. Using capacitance measurements on graphite-gated
van der Waals heterostructures, we find a cascade of density- and electronic displacement
field tuned phase transitions marked by negative electronic compressibility. The
transitions define the boundaries between phases where quantum oscillations have
either four-fold, two-fold, or one-fold degeneracy, associated with a spin and
valley degenerate normal metal, spin-polarized `half-metal', and spin and valley
polarized `quarter metal', respectively. For electron doping, the salient features
are well captured by a phenomenological Stoner model with a valley-anisotropic
Hund's coupling, likely arising from interactions at the lattice scale. For hole
filling, we observe a richer phase diagram featuring a delicate interplay of broken
symmetries and transitions in the Fermi surface topology. Finally, by rotational
alignment of a hexagonal boron nitride substrate to induce a moiré superlattice,
we find that the superlattice perturbs the preexisting isospin order only weakly,
leaving the basic phase diagram intact while catalyzing the formation of topologically
nontrivial gapped states whenever itinerant half- or quarter metal states occur
at half- or quarter superlattice band filling. Our results show that rhombohedral
trilayer graphene is an ideal platform for well-controlled tests of many-body
theory and reveal magnetism in moiré materials to be fundamentally itinerant in
nature.

text: Superconductor-semiconductor hybrids are platforms for realizing effective
p-wave superconductivity. Spin-orbit coupling, combined with the proximity effect,
causes the two-dimensional semiconductor to inherit p±ip intraband pairing, and
application of magnetic field can then result in transitions to the normal state,
partial Bogoliubov Fermi surfaces, or topological phases with Majorana modes.
Experimentally probing the hybrid superconductor-semiconductor interface is challenging
due to the shunting effect of the conventional superconductor. Consequently, the
nature of induced pairing remains an open question. Here, we use the circuit quantum
electrodynamics architecture to probe induced superconductivity in a two dimensional
Al-InAs hybrid system. We observe a strong suppression of superfluid density and
enhanced dissipation driven by magnetic field, which cannot be accounted for by
the depairing theory of an s-wave superconductor. These observations are explained
by a picture of independent intraband p±ip superconductors giving way to partial
Bogoliubov Fermi surfaces, and allow for the first characterization of key properties
of the hybrid superconducting system.

text: "This PhD thesis is primarily focused on the study of discrete transport problems,
introduced for the first time in the seminal works of Maas [Maa11] and Mielke
[Mie11] on finite state Markov chains and reaction-diffusion equations, respectively.
More in detail, my research focuses on the study of transport costs on graphs,
in particular the convergence and the stability of such problems in the discrete-to-continuum
limit. This thesis also includes some results concerning\r\nnon-commutative optimal
transport. The first chapter of this thesis consists of a general introduction
to the optimal transport problems, both in the discrete, the continuous, and the
non-commutative setting. Chapters 2 and 3 present the content of two works, obtained
in collaboration with Peter Gladbach, Eva Kopfer, and Jan Maas, where we have
been able to show the convergence of discrete transport costs on periodic graphs
to suitable continuous ones, which can be described by means of a homogenisation
result. We first focus on the particular case of quadratic costs on the real line
and then extending the result to more general costs in arbitrary dimension. Our
results are the first complete characterisation of limits of transport costs on
periodic graphs in arbitrary dimension which do not rely on any additional symmetry.
In Chapter 4 we turn our attention to one of the intriguing connection between
evolution equations and optimal transport, represented by the theory of gradient
flows. We show that discrete gradient flow structures associated to a finite volume
approximation of a certain class of diffusive equations (Fokker–Planck) is stable
in the limit of vanishing meshes, reproving the convergence of the scheme via
the method of evolutionary Γ-convergence and exploiting a more variational point
of view on the problem. This is based on a collaboration with Dominik Forkert
and Jan Maas. Chapter 5 represents a change of perspective, moving away from the
discrete world and reaching the non-commutative one. As in the discrete case,
we discuss how classical tools coming from the commutative optimal transport can
be translated into the setting of density matrices. In particular, in this final
chapter we present a non-commutative version of the Schrödinger problem (or entropic
regularised optimal transport problem) and discuss existence and characterisation
of minimisers, a duality result, and present a non-commutative version of the
well-known Sinkhorn algorithm to compute the above mentioned optimisers. This
is based on a joint work with Dario Feliciangeli and Augusto Gerolin. Finally,
Appendix A and B contain some additional material and discussions, with particular
attention to Harnack inequalities and the regularity of flows on discrete spaces."

text: The ⊗*-monoidal structure on the category of sheaves on the Ran space is not
pro-nilpotent in the sense of [3]. However, under some connectivity assumptions,
we prove that Koszul duality induces an equivalence of categories and that this
equivalence behaves nicely with respect to Verdier duality on the Ran space and
integrating along the Ran space, i.e. taking factorization homology. Based on
ideas sketched in [4], we show that these results also offer a simpler alternative
to one of the two main steps in the proof of the Atiyah-Bott formula given in
[7] and [5].

text: 'Many security definitions come in two flavors: a stronger “adaptive” flavor,
where the adversary can arbitrarily make various choices during the course of
the attack, and a weaker “selective” flavor where the adversary must commit to
some or all of their choices a-priori. For example, in the context of identity-based
encryption, selective security requires the adversary to decide on the identity
of the attacked party at the very beginning of the game whereas adaptive security
allows the attacker to first see the master public key and some secret keys before
making this choice. Often, it appears to be much easier to achieve selective security
than it is to achieve adaptive security. A series of several recent works shows
how to cleverly achieve adaptive security in several such scenarios including
generalized selective decryption [Pan07][FJP15], constrained PRFs [FKPR14], and
Yao’s garbled circuits [JW16]. Although the above works expressed vague intuition
that they share a common technique, the connection was never made precise. In
this work we present a new framework (published at Crypto ’17 [JKK+17a]) that
connects all of these works and allows us to present them in a unified and simplified
fashion. Having the framework in place, we show how to achieve adaptive security
for proxy re-encryption schemes (published at PKC ’19 [FKKP19]) and provide the
first adaptive security proofs for continuous group key agreement protocols (published
at S&P ’21 [KPW+21]). Questioning optimality of our framework, we then show that
currently used proof techniques cannot lead to significantly better security guarantees
for "graph-building" games (published at TCC ’21 [KKPW21a]). These games cover
generalized selective decryption, as well as the security of prominent constructions
for constrained PRFs, continuous group key agreement, and proxy re-encryption.
Finally, we revisit the adaptive security of Yao’s garbled circuits and extend
the analysis of Jafargholi and Wichs in two directions: While they prove adaptive
security only for a modified construction with increased online complexity, we
provide the first positive results for the original construction by Yao (published
at TCC ’21 [KKP21a]). On the negative side, we prove that the results of Jafargholi
and Wichs are essentially optimal by showing that no black-box reduction can provide
a significantly better security bound (published at Crypto ’21 [KKPW21c]).'
