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: Quantum illumination is a sensing technique that employs entangled signal-idler
beams to improve the detection efficiency of low-reflectivity objects in environments
with large thermal noise. The advantage over classical strategies is evident at
low signal brightness, a feature which could make the protocol an ideal prototype
for non-invasive scanning or low-power short-range radar. Here we experimentally
investigate the concept of quantum illumination at microwave frequencies, by generating
entangled fields using a Josephson parametric converter which are then amplified
to illuminate a room-temperature object at a distance of 1 meter. Starting from
experimental data, we simulate the case of perfect idler photon number detection,
which results in a quantum advantage compared to the relative classical benchmark.
Our results highlight the opportunities and challenges on the way towards a first

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.'

text: We consider the sum of two large Hermitian matrices A and B with a Haar unitary
conjugation bringing them into a general relative position. We prove that the
eigenvalue density on the scale slightly above the local eigenvalue spacing is
asymptotically given by the free additive convolution of the laws of A and B as
the dimension of the matrix increases. This implies optimal rigidity of the eigenvalues
and optimal rate of convergence in Voiculescu's theorem. Our previous works [4],
[5] established these results in the bulk spectrum, the current paper completely
settles the problem at the spectral edges provided they have the typical square-root
behavior. The key element of our proof is to compensate the deterioration of the
stability of the subordination equations by sharp error estimates that properly
account for the local density near the edge. Our results also hold if the Haar
unitary matrix is replaced by the Haar orthogonal matrix.

text: Fitness interactions between mutations can influence a population’s evolution
in many different ways. While epistatic effects are difficult to measure precisely,
important information is captured by the mean and variance of log fitnesses for
individuals carrying different numbers of mutations. We derive predictions for
these quantities from a class of simple fitness landscapes, based on models of
optimizing selection on quantitative traits. We also explore extensions to the
models, including modular pleiotropy, variable effect sizes, mutational bias and
maladaptation of the wild type. We illustrate our approach by reanalysing a large
dataset of mutant effects in a yeast snoRNA. Though characterized by some large
epistatic effects, these data give a good overall fit to the non-epistatic null
model, suggesting that epistasis might have limited influence on the evolutionary
dynamics in this system. We also show how the amount of epistasis depends on both
the underlying fitness landscape and the distribution of mutations, and so is
expected to vary in consistent ways between new mutations, standing variation
and fixed mutations.

text: Fitness interactions between mutations can influence a population’s evolution
in many different ways. While epistatic effects are difficult to measure precisely,
important information is captured by the mean and variance of log fitnesses for
individuals carrying different numbers of mutations. We derive predictions for
these quantities from a class of simple fitness landscapes, based on models of
optimizing selection on quantitative traits. We also explore extensions to the
models, including modular pleiotropy, variable effect sizes, mutational bias and
maladaptation of the wild type. We illustrate our approach by reanalysing a large
dataset of mutant effects in a yeast snoRNA. Though characterized by some large
epistatic effects, these data give a good overall fit to the non-epistatic null
model, suggesting that epistasis might have limited influence on the evolutionary
dynamics in this system. We also show how the amount of epistasis depends on both
the underlying fitness landscape and the distribution of mutations, and so is
expected to vary in consistent ways between new mutations, standing variation
and fixed mutations.

text: We prove a central limit theorem for the difference of linear eigenvalue statistics
of a sample covariance matrix W˜ and its minor W. We find that the fluctuation
of this difference is much smaller than those of the individual linear statistics,
as a consequence of the strong correlation between the eigenvalues of W˜ and W.
Our result identifies the fluctuation of the spatial derivative of the approximate
Gaussian field in the recent paper by Dumitru and Paquette. Unlike in a similar
result for Wigner matrices, for sample covariance matrices, the fluctuation may
entirely vanish.
