text: The 3′,5′-cyclic adenosine monophosphate (cAMP) is a versatile second messenger
in many mammalian signaling pathways. However, its role in plants remains not
well-recognized. Recent discovery of adenylate cyclase (AC) activity for transport
inhibitor response 1/auxin-signaling F-box proteins (TIR1/AFB) auxin receptors
and the demonstration of its importance for canonical auxin signaling put plant
cAMP research back into spotlight. This insight briefly summarizes the well-established
cAMP signaling pathways in mammalian cells and describes the turbulent and controversial
history of plant cAMP research highlighting the major progress and the unresolved
points. We also briefly review the current paradigm of auxin signaling to provide
a background for the discussion on the AC activity of TIR1/AFB auxin receptors
and its potential role in transcriptional auxin signaling as well as impact of
these discoveries on plant cAMP research in general.

text: Three-dimensional (3D) reconstruction of living brain tissue down to an individual
synapse level would create opportunities for decoding the dynamics and structure–function
relationships of the brain’s complex and dense information processing network;
however, this has been hindered by insufficient 3D resolution, inadequate signal-to-noise
ratio and prohibitive light burden in optical imaging, whereas electron microscopy
is inherently static. Here we solved these challenges by developing an integrated
optical/machine-learning technology, LIONESS (live information-optimized nanoscopy
enabling saturated segmentation). This leverages optical modifications to stimulated
emission depletion microscopy in comprehensively, extracellularly labeled tissue
and previous information on sample structure via machine learning to simultaneously
achieve isotropic super-resolution, high signal-to-noise ratio and compatibility
with living tissue. This allows dense deep-learning-based instance segmentation
and 3D reconstruction at a synapse level, incorporating molecular, activity and
morphodynamic information. LIONESS opens up avenues for studying the dynamic functional
(nano-)architecture of living brain tissue.

text: We give a simple argument to prove Nagai’s conjecture for type II degenerations
of compact hyperkähler manifolds and cohomology classes of middle degree. Under
an additional assumption, the techniques yield the conjecture in arbitrary degree.
This would complete the proof of Nagai’s conjecture in general, as it was proved
already for type I degenerations by Kollár, Laza, Saccà, and Voisin [10] and independently
by Soldatenkov [18], while it is immediate for type III degenerations. Our arguments
are close in spirit to a recent paper by Harder [8] proving similar results for
the restrictive class of good degenerations.

text: This paper is a collection of results on combinatorial properties of codes
for the Z-channel . A Z-channel with error fraction τ takes as input a length-
n binary codeword and injects in an adversarial manner up to n τ asymmetric errors,
i.e., errors that only zero out bits but do not flip 0’s to 1’s. It is known that
the largest ( L - 1)-list-decodable code for the Z-channel with error fraction
τ has exponential size (in n ) if τ is less than a critical value that we call
the ( L - 1)- list-decoding Plotkin point and has constant size if τ is larger
than the threshold. The ( L -1)-list-decoding Plotkin point is known to be L -1/L-1
– L -L/ L-1 , which equals 1/4 for unique-decoding with L -1 = 1. In this paper,
we derive various results for the size of the largest codes above and below the
list-decoding Plotkin point. In particular, we show that the largest ( L -1)-list-decodable
code ε-above the Plotkin point, for any given sufficiently small positive constant
ε > 0, has size Θ L (ε -3/2 ) for any L - 1 ≥ 1. We also devise upper and lower
bounds on the exponential size of codes below the list-decoding Plotkin point.

text: "Consider a geodesic triangle on a surface of constant curvature and subdivide
it recursively into four triangles by joining the midpoints of its edges. We show
the existence of a uniform δ>0\r\n such that, at any step of the subdivision,
all the triangle angles lie in the interval (δ,π−δ)\r\n. Additionally, we exhibit
stabilising behaviours for both angles and lengths as this subdivision progresses."

text: "In this paper, we prove the convexity of trace functionals (A,B,C)↦Tr|BpACq|s,\r\nfor
parameters (p, q, s) that are best possible, where B and C are any n-by-n positive-definite
matrices, and A is any n-by-n matrix. We also obtain the monotonicity versions
of trace functionals of this type. As applications, we extend some results in
Carlen et al. (Linear Algebra Appl 490:174–185, 2016), Hiai and Petz (Publ Res
Inst Math Sci 48(3):525-542, 2012) and resolve a conjecture in Al-Rashed and Zegarliński
(Infin Dimens Anal Quantum Probab Relat Top 17(4):1450029, 2014) in the matrix
setting. Other conjectures in Al-Rashed and Zegarliński (Infin Dimens Anal Quantum
Probab Relat Top 17(4):1450029, 2014) will also be discussed. We also show that
some related trace functionals are not concave in general. Such concavity results
were expected to hold in different problems."

text: Viscous flows through pipes and channels are steady and ordered until, with
increasing velocity, the laminar motion catastrophically breaks down and gives
way to turbulence. How this apparently discontinuous change from low- to high-dimensional
motion can be rationalized within the framework of the Navier-Stokes equations
is not well understood. Exploiting geometrical properties of transitional channel
flow we trace turbulence to far lower Reynolds numbers (Re) than previously possible
and identify the complete path that reversibly links fully turbulent motion to
an invariant solution. This precursor of turbulence destabilizes rapidly with
Re, and the accompanying explosive increase in attractor dimension effectively
marks the transition between deterministic and de facto stochastic dynamics.
acknowledgement: We thank Baofang Song as well as the developers of Channelflow for
sharing their numerical codes, and Mukund Vasudevan and Holger Kantz for fruitful
discussions. This work was supported by a grant from the Simons Foundation (662960,

text: Recent experimental advances have inspired the development of theoretical
tools to describe the non-equilibrium dynamics of quantum systems. Among them
an exact representation of quantum spin systems in terms of classical stochastic
processes has been proposed. Here we provide first steps towards the extension
of this stochastic approach to bosonic systems by considering the one-dimensional
quantum quartic oscillator. We show how to exactly parameterize the time evolution
of this prototypical model via the dynamics of a set of classical variables. We
interpret these variables as stochastic processes, which allows us to propose
a novel way to numerically simulate the time evolution of the system. We benchmark
our findings by considering analytically solvable limits and providing alternative
derivations of known results.

text: We present a numerical analysis of spin-1/2 fermions in a one-dimensional
harmonic potential in the presence of a magnetic point-like impurity at the center
of the trap. The model represents a few-body analogue of a magnetic impurity in
the vicinity of an s-wave superconductor. Already for a few particles we find
a ground-state level crossing between sectors with different fermion parities.
We interpret this crossing as a few-body precursor of a quantum phase transition,
which occurs when the impurity "breaks" a Cooper pair. This picture is further
corroborated by analyzing density-density correlations in momentum space. Finally,
we discuss how the system may be realized with existing cold-atoms platforms.

text: Semiconductor-superconductor hybrid systems are the harbour of many intriguing
mesoscopic phenomena. This material combination leads to spatial variations of
the superconducting properties, which gives rise to Andreev bound states (ABSs).
Some of these states might exhibit remarkable properties that render them highly
desirable for topological quantum computing. The most prominent and hunted of
such states are Majorana zero modes (MZMs), quasiparticles equals to their own
quasiparticles that they follow non-abelian statistics. In this thesis, we first
introduce the general framework of such hybrid systems and, then, we unveil a
series of mesoscopic phenomena that we discovered. Firstly, we show tunneling
spectroscopy experiments on full-shell nanowires (NWs) showing that unwanted quantum-dot
states coupled to superconductors (Yu-Shiba-Rusinov states) can mimic MZMs signatures.
Then, we introduce a novel protocol which allowed the integration of tunneling
spectroscopy with Coulomb spectroscopy within the same device. Employing this
approach on both full-shell NWs and partial-shell NWs, we demonstrated that longitudinally
confined states reveal charge transport phenomenology similar to the one expected
for MZMs. These findings shed light on the intricate interplay between superconductivity
and quantum confinement, which brought us to explore another material platform,
i.e. a two-dimensional Germanium hole gas. After developing a robust way to induce
superconductivity in such system, we showed how to engineer the proximity effect
and we revealed a superconducting hard gap. Finally, we created a superconducting
radio frequency driven ideal diode and a generator of non-sinusoidal current-phase
relations. Our results open the path for the exploration of protected superconducting
qubits and more complex hybrid devices in planar Germanium, like Kitaev chains
and hybrid qubit devices.

text: The operator precedence languages (OPLs) represent the largest known subclass
of the context-free languages which enjoys all desirable closure and decidability
properties. This includes the decidability of language inclusion, which is the
ultimate verification problem. Operator precedence grammars, automata, and logics
have been investigated and used, for example, to verify programs with arithmetic
expressions and exceptions (both of which are deterministic pushdown but lie outside
the scope of the visibly pushdown languages). In this paper, we complete the picture
and give, for the first time, an algebraic characterization of the class of OPLs
in the form of a syntactic congruence that has finitely many equivalence classes
exactly for the operator precedence languages. This is a generalization of the
celebrated Myhill-Nerode theorem for the regular languages to OPLs. As one of
the consequences, we show that universality and language inclusion for nondeterministic
operator precedence automata can be solved by an antichain algorithm. Antichain
algorithms avoid determinization and complementation through an explicit subset
construction, by leveraging a quasi-order on words, which allows the pruning of
the search space for counterexample words without sacrificing completeness. Antichain
algorithms can be implemented symbolically, and these implementations are today
the best-performing algorithms in practice for the inclusion of finite automata.
We give a generic construction of the quasi-order needed for antichain algorithms
from a finite syntactic congruence. This yields the first antichain algorithm
for OPLs, an algorithm that solves the ExpTime-hard language inclusion problem
for OPLs in exponential time.

text: Machine-learned systems are in widespread use for making decisions about humans,
and it is important that they are fair, i.e., not biased against individuals based
on sensitive attributes. We present runtime verification of algorithmic fairness
for systems whose models are unknown, but are assumed to have a Markov chain structure.
We introduce a specification language that can model many common algorithmic fairness
properties, such as demographic parity, equal opportunity, and social burden.
We build monitors that observe a long sequence of events as generated by a given
system, and output, after each observation, a quantitative estimate of how fair
or biased the system was on that run until that point in time. The estimate is
proven to be correct modulo a variable error bound and a given confidence level,
where the error bound gets tighter as the observed sequence gets longer. Our monitors
are of two types, and use, respectively, frequentist and Bayesian statistical
inference techniques. While the frequentist monitors compute estimates that are
objectively correct with respect to the ground truth, the Bayesian monitors compute
estimates that are correct subject to a given prior belief about the system’s
model. Using a prototype implementation, we show how we can monitor if a bank
is fair in giving loans to applicants from different social backgrounds, and if
a college is fair in admitting students while maintaining a reasonable financial
burden on the society. Although they exhibit different theoretical complexities
in certain cases, in our experiments, both frequentist and Bayesian monitors took
less than a millisecond to update their verdicts after each observation.

text: "Superconductor/semiconductor hybrid devices have attracted increasing\r\ninterest
in the past years. Superconducting electronics aims to complement\r\nsemiconductor
technology, while hybrid architectures are at the forefront of\r\nnew ideas such
as topological superconductivity and protected qubits. In this\r\nwork, we engineer
the induced superconductivity in two-dimensional germanium\r\nhole gas by varying
the distance between the quantum well and the aluminum. We\r\ndemonstrate a hard
superconducting gap and realize an electrically and flux\r\ntunable superconducting
diode using a superconducting quantum interference\r\ndevice (SQUID). This allows
to tune the current phase relation (CPR), to a\r\nregime where single Cooper pair
tunneling is suppressed, creating a $ \\sin\r\n\\left( 2 \\varphi \\right)$ CPR.
Shapiro experiments complement this\r\ninterpretation and the microwave drive
allows to create a diode with $ \\approx\r\n100 \\%$ efficiency. The reported
results open up the path towards monolithic\r\nintegration of spin qubit devices,
microwave resonators and (protected)\r\nsuperconducting qubits on a silicon technology
compatible platform."

text: The emergence of large-scale order in self-organized systems relies on local
interactions between individual components. During bacterial cell division, FtsZ—a
prokaryotic homologue of the eukaryotic protein tubulin—polymerizes into treadmilling
filaments that further organize into a cytoskeletal ring. In vitro, FtsZ filaments
can form dynamic chiral assemblies. However, how the active and passive properties
of individual filaments relate to these large-scale self-organized structures
remains poorly understood. Here we connect single-filament properties with the
mesoscopic scale by combining minimal active matter simulations and biochemical
reconstitution experiments. We show that the density and flexibility of active
chiral filaments define their global order. At intermediate densities, curved,
flexible filaments organize into chiral rings and polar bands. An effectively
nematic organization dominates for high densities and for straight, mutant filaments
with increased rigidity. Our predicted phase diagram quantitatively captures these
features, demonstrating how the flexibility, density and chirality of the active
filaments affect their collective behaviour. Our findings shed light on the fundamental
properties of active chiral matter and explain how treadmilling FtsZ filaments
organize during bacterial cell division.

text: How do statistical dependencies in measurement noise influence high-dimensional
inference? To answer this, we study the paradigmatic spiked matrix model of principal
components analysis (PCA), where a rank-one matrix is corrupted by additive noise.
We go beyond the usual independence assumption on the noise entries, by drawing
the noise from a low-order polynomial orthogonal matrix ensemble. The resulting
noise correlations make the setting relevant for applications but analytically
challenging. We provide characterization of the Bayes optimal limits of inference
in this model. If the spike is rotation invariant, we show that standard spectral
PCA is optimal. However, for more general priors, both PCA and the existing approximate
message-passing algorithm (AMP) fall short of achieving the information-theoretic
limits, which we compute using the replica method from statistical physics. We
thus propose an AMP, inspired by the theory of adaptive Thouless–Anderson–Palmer
equations, which is empirically observed to saturate the conjectured theoretical
limit. This AMP comes with a rigorous state evolution analysis tracking its performance.
Although we focus on specific noise distributions, our methodology can be generalized
to a wide class of trace matrix ensembles at the cost of more involved expressions.
Finally, despite the seemingly strong assumption of rotation-invariant noise,
our theory empirically predicts algorithmic performance on real data, pointing
at strong universality properties.

text: Although budding yeast has been extensively used as a model organism for studying
organelle functions and intracellular vesicle trafficking, whether it possesses
an independent endocytic early/sorting compartment that sorts endocytic cargos
to the endo-lysosomal pathway or the recycling pathway has long been unclear.
The structure and properties of the endocytic early/sorting compartment differ
significantly between organisms; in plant cells, the trans-Golgi network (TGN)
serves this role, whereas in mammalian cells a separate intracellular structure
performs this function. The yeast syntaxin homolog Tlg2p, widely localizing to
the TGN and endosomal compartments, is presumed to act as a Q-SNARE for endocytic
vesicles, but which compartment is the direct target for endocytic vesicles remained
unanswered. Here we demonstrate by high-speed and high-resolution 4D imaging of
fluorescently labeled endocytic cargos that the Tlg2p-residing compartment within
the TGN functions as the early/sorting compartment. After arriving here, endocytic
cargos are recycled to the plasma membrane or transported to the yeast Rab5-residing
endosomal compartment through the pathway requiring the clathrin adaptors GGAs.
Interestingly, Gga2p predominantly localizes at the Tlg2p-residing compartment,
and the deletion of GGAs has little effect on another TGN region where Sec7p is
present but suppresses dynamics of the Tlg2-residing early/sorting compartment,
indicating that the Tlg2p- and Sec7p-residing regions are discrete entities in
the mutant. Thus, the Tlg2p-residing region seems to serve as an early/sorting
compartment and function independently of the Sec7p-residing region within the
TGN.

text: We prove the Eigenstate Thermalisation Hypothesis (ETH) for local observables
in a typical translation invariant system of quantum spins with L-body interactions,
where L is the number of spins. This mathematically verifies the observation first
made by Santos and Rigol (Phys Rev E 82(3):031130, 2010, https://doi.org/10.1103/PhysRevE.82.031130)
that the ETH may hold for systems with additional translational symmetries for
a naturally restricted class of observables. We also present numerical support
for the same phenomenon for Hamiltonians with local interaction.

text: Bohnenblust–Hille inequalities for Boolean cubes have been proven with dimension-free
constants that grow subexponentially in the degree (Defant et al. in Math Ann
374(1):653–680, 2019). Such inequalities have found great applications in learning
low-degree Boolean functions (Eskenazis and Ivanisvili in Proceedings of the 54th
annual ACM SIGACT symposium on theory of computing, pp 203–207, 2022). Motivated
by learning quantum observables, a qubit analogue of Bohnenblust–Hille inequality
for Boolean cubes was recently conjectured in Rouzé et al. (Quantum Talagrand,
KKL and Friedgut’s theorems and the learnability of quantum Boolean functions,
2022. arXiv preprint arXiv:2209.07279). The conjecture was resolved in Huang et
al. (Learning to predict arbitrary quantum processes, 2022. arXiv preprint arXiv:2210.14894).
In this paper, we give a new proof of these Bohnenblust–Hille inequalities for
qubit system with constants that are dimension-free and of exponential growth
in the degree. As a consequence, we obtain a junta theorem for low-degree polynomials.
Using similar ideas, we also study learning problems of low degree quantum observables
and Bohr’s radius phenomenon on quantum Boolean cubes.
