text: Chromosomes in the eukaryotic nucleus are highly compacted. However, for many
functional processes, including transcription initiation, the pairwise motion
of distal chromosomal elements such as enhancers and promoters is essential and
necessitates dynamic fluidity. Here, we used a live-imaging assay to simultaneously
measure the positions of pairs of enhancers and promoters and their transcriptional
output while systematically varying the genomic separation between these two DNA
loci. Our analysis reveals the coexistence of a compact globular organization
and fast subdiffusive dynamics. These combined features cause an anomalous scaling
of polymer relaxation times with genomic separation leading to long-ranged correlations.
Thus, encounter times of DNA loci are much less dependent on genomic distance
than predicted by existing polymer models, with potential consequences for eukaryotic
gene expression.

text: 'Determining the degree of inherent parallelism in classical sequential algorithms
and leveraging it for fast parallel execution is a key topic in parallel computing,
and detailed analyses are known for a wide range of classical algorithms. In this
paper, we perform the first such analysis for the fundamental Union-Find problem,
in which we are given a graph as a sequence of edges, and must maintain its connectivity
structure under edge additions. We prove that classic sequential algorithms for
this problem are well-parallelizable under reasonable assumptions, addressing
a conjecture by [Blelloch, 2017]. More precisely, we show via a new potential
argument that, under uniform random edge ordering, parallel union-find operations
are unlikely to interfere: T concurrent threads processing the graph in parallel
will encounter memory contention O(T2 · log |V| · log |E|) times in expectation,
where |E| and |V| are the number of edges and nodes in the graph, respectively.
We leverage this result to design a new parallel Union-Find algorithm that is
both internally deterministic, i.e., its results are guaranteed to match those
of a sequential execution, but also work-efficient and scalable, as long as the
number of threads T is O(|E|1 over 3 - ε), for an arbitrarily small constant ε
> 0, which holds for most large real-world graphs. We present lower bounds which
show that our analysis is close to optimal, and experimental results suggesting
that the performance cost of internal determinism is limited.'

text: "Motivation: Boolean networks are simple but efficient mathematical formalism
for modelling complex biological systems. However, having only two levels of activation
is sometimes not enough to fully capture the dynamics of real-world biological
systems. Hence, the need for multi-valued networks (MVNs), a generalization of
Boolean networks. Despite the importance of MVNs for modelling biological systems,
only limited progress has been made on developing theories, analysis methods,
and tools that can support them. In particular, the recent use of trap spaces
in Boolean networks made a great impact on the field of systems biology, but there
has been no similar concept defined and studied for MVNs to date.\r\n\r\nResults:
In this work, we generalize the concept of trap spaces in Boolean networks to
that in MVNs. We then develop the theory and the analysis methods for trap spaces
in MVNs. In particular, we implement all proposed methods in a Python package
called trapmvn. Not only showing the applicability of our approach via a realistic
case study, we also evaluate the time efficiency of the method on a large collection
of real-world models. The experimental results confirm the time efficiency, which
we believe enables more accurate analysis on larger and more complex multi-valued
models."

text: In this study, we propose a computational framework for optimizing the continuity
of the toolpath in fabricating surface models on an extrusion-based 3D printer.
Toolpath continuity is a critical issue that influences both the quality and the
efficiency of extrusion-based fabrication. Transfer moves lead to rough and bumpy
surfaces, where this phenomenon worsens for materials with large viscosity, like
clay. The effects of continuity on the surface models are even more severe in
terms of the quality of the surface and the stability of the model. We introduce
a criterion called the one–path patch (OPP) to represent a patch on the surface
of the shell that can be traversed along one path by considering the constraints
on fabrication. We study the properties of the OPPs and their merging operations
to propose a bottom-up OPP merging procedure to decompose the given shell surface
into a minimal number of OPPs, and to generate the “as-continuous-as-possible”
(ACAP) toolpath. Furthermore, we augment the path planning algorithm with a curved-layer
printing scheme that reduces staircase defects and improves the continuity of
the toolpath by connecting multiple segments. We evaluated the ACAP algorithm
on ceramic and thermoplastic materials, and the results showed that it improves
the fabrication of surface models in terms of both efficiency and surface quality.

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."
