text: 'The developmental strategies used by progenitor cells to endure a safe journey
from their induction place towards the site of terminal differentiation are still
poorly understood. Here we uncovered a progenitor cell allocation mechanism that
stems from an incomplete process of epithelial delamination that allows progenitors
to coordinate their movement with adjacent extra-embryonic tissues. Progenitors
of the zebrafish laterality organ originate from the surface epithelial enveloping
layer by an apical constriction process of cell delamination. During this process,
progenitors retain long-term apical contacts that enable the epithelial layer
to pull a subset of progenitors along their way towards the vegetal pole. The
remaining delaminated progenitors follow apically-attached progenitors’ movement
by a co-attraction mechanism, avoiding sequestration by the adjacent endoderm,
ensuring their fate and collective allocation at the differentiation site. Thus,
we reveal that incomplete delamination serves as a cellular platform for coordinated
tissue movements during development. Impact Statement: Incomplete delamination
serves as a cellular platform for coordinated tissue movements during development,
guiding newly formed progenitor cell groups to the differentiation site.'

text: The family of feedback alignment (FA) algorithms aims to provide a more biologically
motivated alternative to backpropagation (BP), by substituting the computations
that are unrealistic to be implemented in physical brains. While FA algorithms
have been shown to work well in practice, there is a lack of rigorous theory proofing
their learning capabilities. Here we introduce the first feedback alignment algorithm
with provable learning guarantees. In contrast to existing work, we do not require
any assumption about the size or depth of the network except that it has a single
output neuron, i.e., such as for binary classification tasks. We show that our
FA algorithm can deliver its theoretical promises in practice, surpassing the
learning performance of existing FA methods and matching backpropagation in binary
classification tasks. Finally, we demonstrate the limits of our FA variant when
the number of output neurons grows beyond a certain quantity.

text: We propose a neural information processing system obtained by re-purposing
the function of a biological neural circuit model to govern simulated and real-world
control tasks. Inspired by the structure of the nervous system of the soil-worm,
C. elegans, we introduce ordinary neural circuits (ONCs), defined as the model
of biological neural circuits reparameterized for the control of alternative tasks.
We first demonstrate that ONCs realize networks with higher maximum flow compared
to arbitrary wired networks. We then learn instances of ONCs to control a series
of robotic tasks, including the autonomous parking of a real-world rover robot.
For reconfiguration of the purpose of the neural circuit, we adopt a search-based
optimization algorithm. Ordinary neural circuits perform on par and, in some cases,
significantly surpass the performance of contemporary deep learning models. ONC
networks are compact, 77% sparser than their counterpart neural controllers, and
their neural dynamics are fully interpretable at the cell-level.

text: High quality graphene heterostructures host an array of fractional quantum
Hall isospin ferromagnets with diverse spin and valley orders. While a variety
of phase transitions have been observed, disentangling the isospin phase diagram
of these states is hampered by the absence of direct probes of spin and valley
order. I will describe nonlocal transport measurements based on launching spin
waves from a gate defined lateral heterojunction, performed in ultra-clean Corbino
geometry graphene devices. At high magnetic fields, we find that the spin-wave
transport signal is detected in all FQH states between ν = 0 and 1; however, between
ν = 1 and 2 only odd numerator FQH states show finite nonlocal transport, despite
the identical ground state spin polarizations in odd- and even numerator states.
The results reveal that the neutral spin-waves are both spin and sublattice polarized
making them a sensitive probe of ground state sublattice structure. Armed with
this understanding, we use nonlocal transport signal to a magnetic field tuned
isospin phase transition, showing that the emergent even denominator state at
ν = 1/2 in monolayer graphene is indeed a multicomponent state featuring equal
populations on each sublattice.

text: We experimentally investigate twisted van der Waals heterostructures of monolayer
graphene rotated with respect to a bernal stacked graphene bilayer. We report
transport measurements for devices with twist angles between 0.9 and 1.4°. The
electric field allows efficient tuning of the width, isolation and the topology
of the moiré bands in this system. By comparing magnetoresistance measurements
to numerical simulations, we develop an understanding of the band structure. Finally,
we observe correlated states at half- and quarter-fillings, which arise when narrow
moire sublattice band is isolated by energy gaps from dispersive bands. We investigate
the effects of in-plane and out-of-plane magnetic field on these states and discuss
the implication for their spin- and valley- polarization.

text: We report the observation of a quantized anomalous Hall effect in a moiré
heterostructure consisting of twisted bilayer graphene aligned to an encapsulating
hBN substrate. The effect occurs at a density of 3 electrons per superlattice
unit cell, where we observe magnetic hysteresis and a Hall resistance quantized
to within 0.1% of the resistance quantum at temperatures as high as 3K. In this
first of 3 talks, I will describe the fabrication procedure for our device as
well as basic transport characterization measurements. I will introduce the phenomenology
of twisted bilayer graphene and present evidence for hBN alignment as manifested
in the hierarchy of symmetry-breaking gaps and anomalous magnetoresistance.
acknowledgement: I would like to thank the MURI program, Sloan foundation, AFOSR,
and ARO for their generous support of this work.

text: This is the second of three talks describing the observation and characterization
of a ferromagnetic moiré heterostructure based on twisted bilayer graphene aligned
to hexagonal boron nitride. I will compare the qualitative and quantitative features
of this observed quantum anomalous Hall state to traditional systems engineered
from thin film (Bi,Sb)2Te3 topological insulators. In particular, we find that
the measured electronic energy gap of ~30K is several times higher than the Curie
temperature, consistent with a lack of disorder associated with magnetic dopants.
In this system, the quantization arises from spontaneous ferromagnetic polarization
into a single spin and valley moiré subband, which is topological despite the
lack of spin orbit coupling. I will also discuss the observation of current induced
switching, which allows the magnetic state of the heterostructure to be controllably
reversed with currents as small as a few nanoamperes.

text: This is the third of three talks describing the observation and characterization
of a ferromagnetic moiré heterostructure based on twisted bilayer graphene aligned
to hexagonal boron nitride. In this segment I will present scanning probe magnetometry
data acquired using a nanoSQUID-on-tip microscope, which provides ~150 nm spatial
resolution and a field sensitivity of ~10 nT/rtHz. We study the distribution of
magnetic domains within the device as a function of density, magnetic field training,
and DC current. Our data allow us to constrain the magnitude of the orbital magnetic
moment of the electrons in the QAH state. Comparison with simultaneously acquired
transport data allows us to precisely correlate single domain dynamics with discrete
jumps in the observed anomalous Hall signal.

text: Partially filled Landau levels host competing electronic orders. For example,
electron solids may prevail close to integer filling of the Landau levels before
giving way to fractional quantum Hall liquids at higher carrier density1,2. Here,
we report the observation of an electron solid with non-collinear spin texture
in monolayer graphene, consistent with solidification of skyrmions3—topological
spin textures characterized by quantized electrical charge4,5. We probe the spin
texture of the solids using a modified Corbino geometry that allows ferromagnetic
magnons to be launched and detected6,7. We find that magnon transport is highly
efficient when one Landau level is filled (ν=1), consistent with quantum Hall
ferromagnetic spin polarization. However, even minimal doping immediately quenches
the magnon signal while leaving the vanishing low-temperature charge conductivity
unchanged. Our results can be understood by the formation of a solid of charged
skyrmions near ν=1, whose non-collinear spin texture leads to rapid magnon decay.
Data near fractional fillings show evidence of several fractional skyrmion solids,
suggesting that graphene hosts a highly tunable landscape of coupled spin and
charge orders.

text: We introduce in this paper AMT2.0, a tool for qualitative and quantitative
analysis of hybrid continuous and Boolean signals that combine numerical values
and discrete events. The evaluation of the signals is based on rich temporal specifications
expressed in extended signal temporal logic, which integrates timed regular expressions
within signal temporal logic. The tool features qualitative monitoring (property
satisfaction checking), trace diagnostics for explaining and justifying property
violations and specification-driven measurement of quantitative features of the
signal. We demonstrate the tool functionality on several running examples and
case studies, and evaluate its performance.

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: "We introduce the notion of Witness Maps as a cryptographic notion of a proof
system. A Unique Witness Map (UWM) deterministically maps all witnesses for an
\ NP statement to a single representative witness, resulting in a computationally
sound, deterministic-prover, non-interactive witness independent proof system.
A relaxation of UWM, called Compact Witness Map (CWM), maps all the witnesses
to a small number of witnesses, resulting in a “lossy” deterministic-prover, non-interactive
proof-system. We also define a Dual Mode Witness Map (DMWM) which adds an “extractable”
mode to a CWM.\r\nOur main construction is a DMWM for all NP relations, assuming
sub-exponentially secure indistinguishability obfuscation ( iO ), along with
standard cryptographic assumptions. The DMWM construction relies on a CWM and
a new primitive called Cumulative All-Lossy-But-One Trapdoor Functions (C-ALBO-TDF),
both of which are in turn instantiated based on iO and other primitives. Our
instantiation of a CWM is in fact a UWM; in turn, we show that a UWM implies Witness
Encryption. Along the way to constructing UWM and C-ALBO-TDF, we also construct,
from standard assumptions, Puncturable Digital Signatures and a new primitive
called Cumulative Lossy Trapdoor Functions (C-LTDF). The former improves up on
a construction of Bellare et al. (Eurocrypt 2016), who relied on sub-exponentially
secure iO and sub-exponentially secure OWF.\r\nAs an application of our constructions,
we show how to use a DMWM to construct the first leakage and tamper-resilient
signatures with a deterministic signer, thereby solving a decade old open problem
posed by Katz and Vaikunthanathan (Asiacrypt 2009), by Boyle, Segev and Wichs
(Eurocrypt 2011), as well as by Faonio and Venturi (Asiacrypt 2016). Our construction
achieves the optimal leakage rate of 1−o(1) ."

text: Recent discoveries have shown that, when two layers of van der Waals (vdW)
materials are superimposed with a relative twist angle between them, the electronic
properties of the coupled system can be dramatically altered. Here, we demonstrate
that a similar concept can be extended to the optics realm, particularly to propagating
phonon polaritons–hybrid light-matter interactions. To do this, we fabricate stacks
composed of two twisted slabs of a vdW crystal (α-MoO3) supporting anisotropic
phonon polaritons (PhPs), and image the propagation of the latter when launched
by localized sources. Our images reveal that, under a critical angle, the PhPs
isofrequency curve undergoes a topological transition, in which the propagation
of PhPs is strongly guided (canalization regime) along predetermined directions
without geometric spreading. These results demonstrate a new degree of freedom
(twist angle) for controlling the propagation of polaritons at the nanoscale with
potential for nanoimaging, (bio)-sensing, or heat management.

text: In recent years, the nuclear pore complex (NPC) has emerged as a key player
in genome regulation and cellular homeostasis. New discoveries have revealed that
the NPC has multiple cellular functions besides mediating the molecular exchange
between the nucleus and the cytoplasm. In this review, we discuss non-transport
aspects of the NPC focusing on the NPC-genome interaction, the extreme longevity
of the NPC proteins, and NPC dysfunction in age-related diseases. The examples
summarized herein demonstrate that the NPC, which first evolved to enable the
biochemical communication between the nucleus and the cytoplasm, now doubles as
the gatekeeper of cellular identity and aging.

an unresolved experimental challenge. Here, we generated induced vascular endothelial
cells (iVECs) and smooth muscle cells (iSMCs) by direct reprogramming of healthy
human fibroblasts from donors of different ages and Hutchinson-Gilford Progeria
Syndrome (HGPS) patients. iVECs induced from old donors revealed upregulation
of GSTM1 and PALD1, genes linked to oxidative stress, inflammation and endothelial
junction stability, as vascular aging markers. A functional assay performed on
PALD1 KD VECs demonstrated a recovery in vascular permeability. We found that
iSMCs from HGPS donors overexpressed bone morphogenetic protein (BMP)−4, which
plays a key role in both vascular calcification and endothelial barrier damage
observed in HGPS. Strikingly, BMP4 concentrations are higher in serum from HGPS
vs. age-matched mice. Furthermore, targeting BMP4 with blocking antibody recovered
the functionality of the vascular barrier in vitro, hence representing a potential
future therapeutic strategy to limit cardiovascular dysfunction in HGPS. These
results show that iVECs and iSMCs retain disease-related signatures, allowing
modeling of vascular aging and HGPS in vitro.

text: Aging of the circulatory system correlates with the pathogenesis of a large
spectrum of diseases. However, it is largely unknown which factors drive the age-dependent
or pathological decline of the vasculature and how vascular defects relate to
tissue aging. The goal of the study is to design a multianalytical approach to
identify how the cellular microenvironment (i.e., fibroblasts) and serum from
healthy donors of different ages or Alzheimer disease (AD) patients can modulate
the functionality of organ-specific vascular endothelial cells (VECs). Long-living
human microvascular networks embedding VECs and fibroblasts from skin biopsies
are generated. RNA-seq, secretome analyses, and microfluidic assays demonstrate
that fibroblasts from young donors restore the functionality of aged endothelial
cells, an effect also achieved by serum from young donors. New biomarkers of vascular
aging are validated in human biopsies and it is shown that young serum induces
angiopoietin-like-4, which can restore compromised vascular barriers. This strategy
is then employed to characterize transcriptional/functional changes induced on
the blood–brain barrier by AD serum, demonstrating the importance of PTP4A3 in
the regulation of permeability. Features of vascular degeneration during aging
and AD are recapitulated, and a tool to identify novel biomarkers that can be
exploited to develop future therapeutics modulating vascular function is established.

text: During mitosis, transcription of genomic DNA is dramatically reduced, before
it is reactivated during nuclear reformation in anaphase/telophase. Many aspects
of the underlying principles that mediate transcriptional memory and reactivation
in the daughter cells remain unclear. Here, we used ChIP-seq on synchronized cells
at different stages after mitosis to generate genome-wide maps of histone modifications.
Combined with EU-RNA-seq and Hi-C analyses, we found that during prometaphase,
promoters, enhancers, and insulators retain H3K4me3 and H3K4me1, while losing
H3K27ac. Enhancers globally retaining mitotic H3K4me1 or locally retaining mitotic
H3K27ac are associated with cell type-specific genes and their transcription factors
for rapid transcriptional activation. As cells exit mitosis, promoters regain
H3K27ac, which correlates with transcriptional reactivation. Insulators also gain
H3K27ac and CCCTC-binding factor (CTCF) in anaphase/telophase. This increase of
H3K27ac in anaphase/telophase is required for posttranscriptional activation and
may play a role in the establishment of topologically associating domains (TADs).
Together, our results suggest that the genome is reorganized in a sequential order,
in which histone methylations occur first in prometaphase, histone acetylation,
and CTCF in anaphase/telophase, transcription in cytokinesis, and long-range chromatin
interactions in early G1. We thus provide insights into the histone modification
landscape that allows faithful reestablishment of the transcriptional program
and TADs during cell division.

text: Nucleoporin 93 (Nup93) expression inversely correlates with the survival of
triple-negative breast cancer patients. However, our knowledge of Nup93 function
in breast cancer besides its role as structural component of the nuclear pore
complex is not understood. Combination of functional assays and genetic analyses
suggested that chromatin interaction of Nup93 partially modulates the expression
of genes associated with actin cytoskeleton remodeling and epithelial to mesenchymal
transition, resulting in impaired invasion of triple-negative, claudin-low breast
cancer cells. Nup93 depletion induced stress fiber formation associated with reduced
cell migration/proliferation and impaired expression of mesenchymal-like genes.
Silencing LIMCH1, a gene responsible for actin cytoskeleton remodeling and up-regulated
upon Nup93 depletion, partially restored the invasive phenotype of cancer cells.
Loss of Nup93 led to significant defects in tumor establishment/propagation in
vivo, whereas patient samples revealed that high Nup93 and low LIMCH1 expression
correlate with late tumor stage. Our approach identified Nup93 as contributor
of triple-negative, claudin-low breast cancer cell invasion and paves the way
to study the role of nuclear envelope proteins during breast cancer tumorigenesis.

text: We investigated the ultraviolet (UV) spectral properties of faint Lyman-α
emitters (LAEs) in the redshift range 2.9 ≤ z ≤ 4.6, and we provide material to
prepare future observations of the faint Universe. We used data from the MUSE
Hubble Ultra Deep Survey to construct mean rest-frame spectra of continuum-faint
(median MUV of −18 and down to MUV of −16), low stellar mass (median value of
108.4 M⊙ and down to 107 M⊙) LAEs at redshift z ≳ 3. We computed various averaged
spectra of LAEs, subsampled on the basis of their observational (e.g., Lyα strength,
UV magnitude and spectral slope) and physical (e.g., stellar mass and star-formation
rate) properties. We searched for UV spectral features other than Lyα, such as
higher ionization nebular emission lines and absorption features. We successfully
observed the O III]λ1666 and [C III]λ1907+C III]λ1909 collisionally excited emission
lines and the He IIλ1640 recombination feature, as well as the resonant C IVλλ1548,1551
doublet either in emission or P-Cygni. We compared the observed spectral properties
of the different mean spectra and find the emission lines to vary with the observational
and physical properties of the LAEs. In particular, the mean spectra of LAEs with
larger Lyα equivalent widths, fainter UV magnitudes, bluer UV spectral slopes,
and lower stellar masses show the strongest nebular emission. The line ratios
of these lines are similar to those measured in the spectra of local metal-poor
galaxies, while their equivalent widths are weaker compared to the handful of
extreme values detected in individual spectra of z > 2 galaxies. This suggests
that weak UV features are likely ubiquitous in high z, low-mass, and faint LAEs.
We publicly released the stacked spectra, as they can serve as empirical templates
for the design of future observations, such as those with the James Webb Space
Telescope and the Extremely Large Telescope.
