text: Reachability analysis aims at identifying states reachable by a system within
a given time horizon. This task is known to be computationally expensive for linear
hybrid systems. Reachability analysis works by iteratively applying continuous
and discrete post operators to compute states reachable according to continuous
and discrete dynamics, respectively. In this paper, we enhance both of these operators
and make sure that most of the involved computations are performed in low-dimensional
state space. In particular, we improve the continuous-post operator by performing
computations in high-dimensional state space only for time intervals relevant
for the subsequent application of the discrete-post operator. Furthermore, the
new discrete-post operator performs low-dimensional computations by leveraging
the structure of the guard and assignment of a considered transition. We illustrate
the potential of our approach on a number of challenging benchmarks.

text: 'Maintaining fertility in a fluctuating environment is key to the reproductive
success of flowering plants. Meiosis and pollen formation are particularly sensitive
to changes in growing conditions, especially temperature. We have previously identified
cyclin-dependent kinase G1 (CDKG1) as a master regulator of temperature-dependent
meiosis and this may involve the regulation of alternative splicing (AS), including
of its own transcript. CDKG1 mRNA can undergo several AS events, potentially producing
two protein variants: CDKG1L and CDKG1S, differing in their N-terminal domain
which may be involved in co-factor interaction. In leaves, both isoforms have
distinct temperature-dependent functions on target mRNA processing, but their
role in pollen development is unknown. In the present study, we characterize the
role of CDKG1L and CDKG1S in maintaining Arabidopsis fertility. We show that the
long (L) form is necessary and sufficient to rescue the fertility defects of the
cdkg1-1 mutant, while the short (S) form is unable to rescue fertility. On the
other hand, an extra copy of CDKG1L reduces fertility. In addition, mutation of
the ATP binding pocket of the kinase indicates that kinase activity is necessary
for the function of CDKG1. Kinase mutants of CDKG1L and CDKG1S correctly localize
to the cell nucleus and nucleus and cytoplasm, respectively, but are unable to
rescue either the fertility or the splicing defects of the cdkg1-1 mutant. Furthermore,
we show that there is partial functional overlap between CDKG1 and its paralog
CDKG2 that could in part be explained by overlapping gene expression.'

text: "Superconductor insulator transition in transverse magnetic field is studied
in the highly disordered MoC film with the product of the Fermi momentum and the
mean free path kF*l close to unity. Surprisingly, the Zeeman paramagnetic effects
dominate over orbital coupling on both sides of the transition. In superconducting
state it is evidenced by a high upper critical magnetic field \U0001D435\U0001D4502,
by its square root dependence on temperature, as well as by the Zeeman splitting
of the quasiparticle density of states (DOS) measured by scanning tunneling microscopy.
At \U0001D435\U0001D4502 a logarithmic anomaly in DOS is observed. This anomaly
is further enhanced in increasing magnetic field, which is explained by the Zeeman
splitting of the Altshuler-Aronov DOS driving\r\nthe system into a more insulating
or resistive state. Spin dependent Altshuler-Aronov correction is also needed
to explain the transport behavior above \U0001D435\U0001D4502."

text: Skeletal muscle activity is continuously modulated across physiologic states
to provide coordination, flexibility and responsiveness to body tasks and external
inputs. Despite the central role the muscular system plays in facilitating vital
body functions, the network of brain-muscle interactions required to control hundreds
of muscles and synchronize their activation in relation to distinct physiologic
states has not been investigated. Recent approaches have focused on general associations
between individual brain rhythms and muscle activation during movement tasks.
However, the specific forms of coupling, the functional network of cortico-muscular
coordination, and how network structure and dynamics are modulated by autonomic
regulation across physiologic states remains unknown. To identify and quantify
the cortico-muscular interaction network and uncover basic features of neuro-autonomic
control of muscle function, we investigate the coupling between synchronous bursts
in cortical rhythms and peripheral muscle activation during sleep and wake. Utilizing
the concept of time delay stability and a novel network physiology approach, we
find that the brain-muscle network exhibits complex dynamic patterns of communication
involving multiple brain rhythms across cortical locations and different electromyographic
frequency bands. Moreover, our results show that during each physiologic state
the cortico-muscular network is characterized by a specific profile of network
links strength, where particular brain rhythms play role of main mediators of
interaction and control. Further, we discover a hierarchical reorganization in
network structure across physiologic states, with high connectivity and network
link strength during wake, intermediate during REM and light sleep, and low during
deep sleep, a sleep-stage stratification that demonstrates a unique association
between physiologic states and cortico-muscular network structure. The reported
empirical observations are consistent across individual subjects, indicating universal
behavior in network structure and dynamics, and high sensitivity of cortico-muscular
control to changes in autonomic regulation, even at low levels of physical activity
and muscle tone during sleep. Our findings demonstrate previously unrecognized
basic principles of brain-muscle network communication and control, and provide
new perspectives on the regulatory mechanisms of brain dynamics and locomotor
activation, with potential clinical implications for neurodegenerative, movement
and sleep disorders, and for developing efficient treatment strategies.

text: Development of the nervous system undergoes important transitions,
including one from neurogenesis to gliogenesis which occurs late during embryonic
gestation. Here we report on clonal analysis of gliogenesis in mice using Mosaic
Analysis with Double Markers (MADM) with quantitative and computational methods.
Results reveal that developmental gliogenesis in the cerebral cortex occurs in
a fraction of earlier neurogenic clones, accelerating around E16.5, and giving
rise to both astrocytes and oligodendrocytes. Moreover, MADM-based genetic deletion
of the epidermal growth factor receptor (Egfr) in gliogenic clones revealed that
Egfr is cell autonomously required for gliogenesis in the mouse dorsolateral cortices.
A broad range in the proliferation capacity, symmetry of clones, and competitive
advantage of MADM cells was evident in clones that contained one cellular lineage
with double dosage of Egfr relative to their environment, while their sibling
Egfr-null cells failed to generate glia. Remarkably, the total numbers of glia
in MADM clones balance out regardless of significant alterations in clonal symmetries.
The variability in glial clones shows stochastic patterns that we define mathematically,
which are different from the deterministic patterns in neuronal clones. This study
sets a foundation for studying the biological significance of stochastic and deterministic
clonal principles underlying tissue development, and identifying mechanisms that
differentiate between neurogenesis and gliogenesis.

text: The actin-related protein (Arp)2/3 complex nucleates branched actin filament
networks pivotal for cell migration, endocytosis and pathogen infection. Its activation
is tightly regulated and involves complex structural rearrangements and actin
filament binding, which are yet to be understood. Here, we report a 9.0 Å resolution
structure of the actin filament Arp2/3 complex branch junction in cells using
cryo-electron tomography and subtomogram averaging. This allows us to generate
an accurate model of the active Arp2/3 complex in the branch junction and its
interaction with actin filaments. Notably, our model reveals a previously undescribed
set of interactions of the Arp2/3 complex with the mother filament, significantly
different to the previous branch junction model. Our structure also indicates
a central role for the ArpC3 subunit in stabilizing the active conformation.

text: "Currently several projects aim at designing and implementing protocols for
privacy preserving automated contact tracing to help fight the current pandemic.
Those proposal are quite similar, and in their most basic form basically propose
an app for mobile phones which broadcasts frequently changing pseudorandom identifiers
via (low energy) Bluetooth, and at the same time, the app stores IDs broadcast
by phones in its proximity. Only if a user is tested positive, they upload either
the beacons they did broadcast (which is the case in decentralized proposals as
DP-3T, east and west coast PACT or Covid watch) or received (as in Popp-PT or
ROBERT) during the last two weeks or so.\r\n\r\nVaudenay [eprint 2020/399] observes
that this basic scheme (he considers the DP-3T proposal) succumbs to relay and
even replay attacks, and proposes more complex interactive schemes which prevent
those attacks without giving up too many privacy aspects. Unfortunately interaction
is problematic for this application for efficiency and security reasons. The countermeasures
that have been suggested so far are either not practical or give up on key privacy
aspects. We propose a simple non-interactive variant of the basic protocol that\r\n(security)
Provably prevents replay and (if location data is available) relay attacks.\r\n(privacy)
The data of all parties (even jointly) reveals no information on the location
or time where encounters happened.\r\n(efficiency) The broadcasted message can
fit into 128 bits and uses only basic crypto (commitments and secret key authentication).\r\n\r\nTowards
this end we introduce the concept of “delayed authentication”, which basically
is a message authentication code where verification can be done in two steps,
where the first doesn’t require the key, and the second doesn’t require the message."

text: 'In prokaryotes, thermodynamic models of gene regulation provide a highly
quantitative mapping from promoter sequences to gene-expression levels that is
compatible with in vivo and in vitro biophysical measurements. Such concordance
has not been achieved for models of enhancer function in eukaryotes. In equilibrium
models, it is difficult to reconcile the reported short transcription factor (TF)
residence times on the DNA with the high specificity of regulation. In nonequilibrium
models, progress is difficult due to an explosion in the number of parameters.
Here, we navigate this complexity by looking for minimal nonequilibrium enhancer
models that yield desired regulatory phenotypes: low TF residence time, high specificity,
and tunable cooperativity. We find that a single extra parameter, interpretable
as the “linking rate,” by which bound TFs interact with Mediator components, enables
our models to escape equilibrium bounds and access optimal regulatory phenotypes,
while remaining consistent with the reported phenomenology and simple enough to
be inferred from upcoming experiments. We further find that high specificity in
nonequilibrium models is in a trade-off with gene-expression noise, predicting
bursty dynamics—an experimentally observed hallmark of eukaryotic transcription.
By drastically reducing the vast parameter space of nonequilibrium enhancer models
to a much smaller subspace that optimally realizes biological function, we deliver
a rich class of models that could be tractably inferred from data in the near
future.'

text: Quantum illumination uses entangled signal-idler photon pairs to boost the
detection efficiency of low-reflectivity objects in environments with bright thermal
noise. Its advantage is particularly evident at low signal powers, a promising
feature for applications such as noninvasive biomedical scanning or low-power
short-range radar. Here, we experimentally investigate the concept of quantum
illumination at microwave frequencies. We generate entangled fields to illuminate
a room-temperature object at a distance of 1 m in a free-space detection setup.
We implement a digital phase-conjugate receiver based on linear quadrature measurements
that outperforms a symmetric classical noise radar in the same conditions, despite
the entanglement-breaking signal path. Starting from experimental data, we also
simulate the case of perfect idler photon number detection, which results in a
quantum advantage compared with the relative classical benchmark. Our results
highlight the opportunities and challenges in the way toward a first room-temperature
application of microwave quantum circuits.

text: "Microwave photonics lends the advantages of fiber optics to electronic sensing
and communication systems. In contrast to nonlinear optics, electro-optic devices
so far require classical modulation fields whose variance is dominated by electronic
or thermal noise rather than quantum fluctuations. Here we demonstrate bidirectional
single-sideband conversion of X band microwave to C band telecom light with a
microwave mode occupancy as low as 0.025 ± 0.005 and an added output noise of
less than or equal to 0.074 photons. This is facilitated by radiative cooling
and a triply resonant ultra-low-loss transducer operating at millikelvin temperatures.
The high bandwidth of 10.7 MHz and total (internal) photon conversion\r\nefficiency
of 0.03% (0.67%) combined with the extremely slow heating rate of 1.1 added output
noise photons per second for the highest available pump power of 1.48 mW puts
near-unity efficiency pulsed quantum transduction within reach. Together with
the non-Gaussian resources of superconducting qubits this might provide the practical
foundation to extend the range and scope of current quantum networks in analogy
to electrical repeaters in classical fiber optic communication."

text: Quantum transduction, the process of converting quantum signals from one form
of energy to another, is an important area of quantum science and technology.
The present perspective article reviews quantum transduction between microwave
and optical photons, an area that has recently seen a lot of activity and progress
because of its relevance for connecting superconducting quantum processors over
long distances, among other applications. Our review covers the leading approaches
to achieving such transduction, with an emphasis on those based on atomic ensembles,
opto-electro-mechanics, and electro-optics. We briefly discuss relevant metrics
from the point of view of different applications, as well as challenges for the
future.

text: We give a short and self-contained proof for rates of convergence of the Allen--Cahn
equation towards mean curvature flow, assuming that a classical (smooth) solution
to the latter exists and starting from well-prepared initial data. Our approach
is based on a relative entropy technique. In particular, it does not require a
stability analysis for the linearized Allen--Cahn operator. As our analysis also
does not rely on the comparison principle, we expect it to be applicable to more
complex equations and systems.

text: We consider the free additive convolution of two probability measures μ and
ν on the real line and show that μ ⊞ v is supported on a single interval if μ
and ν each has single interval support. Moreover, the density of μ ⊞ ν is proven
to vanish as a square root near the edges of its support if both μ and ν have
power law behavior with exponents between −1 and 1 near their edges. In particular,
these results show the ubiquity of the conditions in our recent work on optimal
local law at the spectral edges for addition of random matrices [5].

text: Quantum information technology based on solid state qubits has created much
interest in converting quantum states from the microwave to the optical domain.
Optical photons, unlike microwave photons, can be transmitted by fiber, making
them suitable for long distance quantum communication. Moreover, the optical domain
offers access to a large set of very well‐developed quantum optical tools, such
as highly efficient single‐photon detectors and long‐lived quantum memories. For
a high fidelity microwave to optical transducer, efficient conversion at single
photon level and low added noise is needed. Currently, the most promising approaches
to build such systems are based on second‐order nonlinear phenomena such as optomechanical
and electro‐optic interactions. Alternative approaches, although not yet as efficient,
include magneto‐optical coupling and schemes based on isolated quantum systems
like atoms, ions, or quantum dots. Herein, the necessary theoretical foundations
for the most important microwave‐to‐optical conversion experiments are provided,
their implementations are described, and the current limitations and future prospects
are discussed.

text: "Distributed ledgers provide high availability and integrity, making them
a key enabler for practical and secure computation of distributed workloads among
mutually distrustful parties. Many practical applications also require strong
confidentiality, however. This work enhances permissioned and permissionless blockchains
with the ability to manage confidential data without forfeiting availability or
decentralization. The proposed Calypso architecture addresses two orthogonal challenges
confronting modern distributed ledgers: (a) enabling the auditable management
of secrets and (b) protecting distributed computations against arbitrage attacks
when their results depend on the ordering and secrecy of inputs.\r\n\r\nCalypso
introduces on-chain secrets, a novel abstraction that enforces atomic deposition
of an auditable trace whenever users access confidential data. Calypso provides
user-controlled consent management that ensures revocation atomicity and accountable
anonymity. To enable permissionless deployment, we introduce an incentive scheme
and provide users with the option to select their preferred trustees. We evaluated
our Calypso prototype with a confidential document-sharing application and a decentralized
lottery. Our benchmarks show that transaction-processing latency increases linearly
in terms of security (number of trustees) and is in the range of 0.2 to 8 seconds
for 16 to 128 trustees."

text: 'Many-body localization provides a mechanism to avoid thermalization in isolated
interacting quantum systems. The breakdown of thermalization may be complete,
when all eigenstates in the many-body spectrum become localized, or partial, when
the so-called many-body mobility edge separates localized and delocalized parts
of the spectrum. Previously, De Roeck et al. [Phys. Rev. B 93, 014203 (2016)]
suggested a possible instability of the many-body mobility edge in energy density.
The local ergodic regions—so-called “bubbles”—resonantly spread throughout the
system, leading to delocalization. In order to study such instability mechanism,
in this work we design a model featuring many-body mobility edge in particle density:
the states at small particle density are localized, while increasing the density
of particles leads to delocalization. Using numerical simulations with matrix
product states, we demonstrate the stability of many-body localization with respect
to small bubbles in large dilute systems for experimentally relevant timescales.
In addition, we demonstrate that processes where the bubble spreads are favored
over processes that lead to resonant tunneling, suggesting a possible mechanism
behind the observed stability of many-body mobility edge. We conclude by proposing
experiments to probe particle density mobility edge in the Bose-Hubbard model.'
