text: "Background & Aims: To develop and validate a CT-based radiomics model to
assess HVPG and predict a composite endpoint of liver-related events (LRE: decompensation
and liver-related death) in patients with cirrhosis.\r\n\r\nMethods: This retrospective
study included 357 cirrhosis patients, who received invasive HVPG measurements,
120 liver-healthy controls (training cohort) and 85 and 100 cirrhosis patients
(internal and external validation cohorts, respectively), and contrast-enhanced
abdominal CTs. After volumetric segmentation of the liver and spleen on CT, Bayesian
parameter optimization was used for selection of extracted features and hyperparameter
tuning in random forest or elastic net models. Prediction accuracy was evaluated
using Pearson correlation coefficients of predicted (’radio-HVPG’) and invasive
HVPG. Discrimination between relevant HVPG cut-offs was determined by receiver
operating characteristic (ROC) analysis. The predictive value of radio-HVPG and
invasive-HVPG for LRE was compared using Cox regression models.\r\n\r\nResults:
Radio-HVPG, predicted by an optimized random forest model based on 74 selected
CT features, correlated with invasive-HVPG and detected clinically significant
portal hypertension (CSPH: HVPG ≥ 10 mmHg) on the internal (Pearson r = 0.63,
AUC 0.89 [95% CI: 0.81–0.96]) and external (Pearson r = 0.62, AUC 0.80 [95% CI:
0.64–0.91]) validation cohorts. Radio-HVPG predicted LRE when adjusting for MELD
and albumin (adjusted HR: 1.14 [95% CI: 1.04–1.25], p = 0.005) and performed similarly
to invasive-HVPG.\r\n\r\nConclusions: Radiomic features accurately predict HVPG
in patients with cirrhosis and allow risk stratification for LRE in a radiomics-clinical
signature."

text: The transport properties of nanofluidic channels are usually studied under
constant (DC) voltage or pressure driving. However, the frequency response under
sinusoidal (AC) drivings offers rich insights into the time-dependent transport
mechanisms. Inspired by recent electrochemical approaches, we investigate the
couplings between ionic and electronic transport under AC driving. We show that
conduction electrons of the channel walls participate in ionic current via capacitive
electrochemical coupling, defining a critical frequency and length scale where
electron-dominated conductivity emerges. We further analyze how electron–ion coupling
modifies electro-osmotic flows and demonstrate that fluctuation-induced momentum
transfer between the electrolyte and wall electrons produces distinct AC transport
signatures, depending on the charge carrier polarity. Altogether, we establish
a frequency-dependent transport matrix that couples ionic, electronic, and hydrodynamic
flows. These findings establish AC nanofluidic transport as a powerful probe of
interfacial phenomena under confinement and suggest new directions for engineering
nanofluidic functionalities through electron–electrolyte coupling.

text: The long-standing notion that genotypes map to phenotypes through simple one
gene–one trait relationships continues to shape both research in the life sciences
and public understanding, with implications for policy and funding priorities.
Yet this paradigm is increasingly recognized as inadequate for explaining continuous
phenotypic variation and the complex genetic architectures of the genotype–phenotype
map. Modern genetics emerged from the early 20th-century synthesis of Mendelian
and biometric schools of heredity, with R.A. Fisher demonstrating early on how
multiple discrete loci could collectively produce continuous variation. Despite
this fundamental insight, Mendelism—with its focus on single genes and standardized
genetic backgrounds—became the dominant framework, shaping current genetics research
and molecular biology as well as science education. The advent of large-scale
genomic data has revealed yet again the limitations of this reductionist approach.
Evidence from quantitative genetics now shows that most phenotypes arise from
complex networks of many interdependent genes and their dynamic responses to environmental
perturbations. Here we trace the historical roots of how Mendelian classical genetics
departed from the biometric school to create the current predominant paradigm
in genetics, despite fundamentally unresolved issues. Moving on from this one-sided
paradigm will require systematic development of integrative, evolutionarily grounded
experimental approaches that better capture the multigenic and context-dependent
nature of inheritance. Achieving such an extended perspective will require methodological
innovation, including advances in large-scale (e.g. automated) phenotyping. Dedicated
research programs will be necessary to advance a new era of genetic research into
the complex mechanisms underlying phenotypic variation.
acknowledgement: We thank a variety of further colleagues for the many inspiring discussions
on the nature of heredity, especially the workshops in Berlin. Special thanks also
to the Stellenbosch Institute for Advanced Studies (STIAS) to provide DT the leisure
and freedom to write up the first version of this perspective. Thanks also to three
reviewers who have helped to improve the manuscript. Two dedicated symposia on the
topic were funded by the Max-Planck Society.

text: "AM CVn stars are ultra-compact semi-detached binaries consisting of a white
dwarf primary and a hydrogen-depleted secondary. In this\r\npaper, we present
spectroscopic and photometric results of 15 transient sources pre-classified as
AM CVn candidates. Our analysis confirms\r\n9 systems of the type AM CVn, 3 hydrogen-rich
cataclysmic variables (accreting white dwarfs with near-main-sequence stars for
donors),\r\nand 3 systems that could be evolved cataclysmic variables. Eight of
the AM CVn stars are analysed spectroscopically for the first time,\r\nwhich increases
the number of spectroscopically confirmed AM CVns by about 10%. TESS data revealed
the orbital period of the AM CVn\r\nstar ASASSN-20pv to be Porb =27.282 min, which
helps to constrain the possible values of its mass ratio. TESS also helped to
determine\r\nthe superhump periods of one AM CVn star (ASASSN-19ct, Psh =30.94
min) and two cataclysmic variables we classify as WZ Sge stars\r\n(Psh =90.77
min for ZTF18aaaasnn and Psh =91.6min for ASASSN-15na).We identified very different
abundances in the spectra of theAM\r\nCVns binaries ASASSN-15kf and ASASSN-20pv
(both Porb ∼27.5min), suggesting different type of donors. Six of the studied
AMCVns are\r\nX-ray sources, which helped to determine their mass accretion rates.
Photometry shows that the duration of all the superoutbursts detected\r\nin the
AM CVns is consistent with expectations from the disc instability model. Finally,
we provide refined criteria for the identification of\r\nnew systems using all-sky
surveys such as LSST."

text: Little red dots (LRDs) are a newly identified class of broad-line active galactic
nuclei (AGNs) with a distinctive V-shaped spectrum characterized by red optical
and blue UV continuum emission. Their high abundance at redshifts of z ∼ 6–8 and
decline at lower redshifts suggest a transient origin. We propose that the spectral
shape of LRDs originates from compact binary black hole systems, in which each
black hole is surrounded by a mini-disk and embedded within a larger circumbinary
disk. With a binary separation of ≲103 Schwarzschild radii, the Wien tail of a
T ≃ 5000 K blackbody spectrum at the inner edge of the circumbinary disk produces
the red optical emission, while the mini-disks power the UV continuum. Binary
torques carve out a gap between the circumbinary disk and the mini-disks, setting
the turnover wavelength of the V-shaped spectrum around the Balmer limit. This
scenario naturally reproduces LRD spectra requiring only modest dust attenuation
(AV ≲ 1 mag), resolving overestimated luminosities for LRDs in previous studies
and alleviating a tension with the so-called Sołtan argument. This model predicts
distinct spectral evolution as the binary orbit decays through binary disk interactions
and gravitational-wave (GW) emission, linking early-stage “proto-LRD” binaries
to the broader AGN population and late-stage “LRD descendants” to coalescing binaries
detectable in GW experiments.

text: UTe2 exhibits the remarkable phenomenon of re-entrant superconductivity, whereby
the zero-resistance state reappears above 40 tesla after being suppressed with
a field of around 10 tesla. One potential pairing mechanism, invoked in the related
re-entrant superconductors UCoGe and URhGe, involves transverse fluctuations of
a ferromagnetic order parameter. However, the requisite ferromagnetic order—present
in both UCoGe and URhGe—is absent in UTe2, and neutron scattering shows instead
that the magnetic susceptibility is peaked at an antiferromagnetic wavevector.
Here, we measure the magnetotropic susceptibility of UTe2 across two field-angle
planes. This quantity is sensitive to the magnetic susceptibility in a direction
transverse to the applied magnetic field—a quantity that is not accessed in conventional
magnetization measurements. We observe a very large decrease in the magnetotropic
susceptibility over a broad range of field orientations, indicating a large increase
in the transverse magnetic susceptibility. Because our technique probes the magnetic
susceptibility in the long wavelength (q = 0) limit, this suggests that the strong
transverse susceptibility arises from ferromagnetic spin fluctuations. These ferromagnetic
fluctuations are likely important for understanding the pairing mechanism in UTe2,
as all three superconducting phases of UTe2 surround this region of enhanced susceptibility
in the field-angle phase diagram.

text: 'We compile a sample of 83 little red dots (LRDs) with JWST imaging and find
that a substantial fraction (∼43%, rising to ≳80% for the most luminous LRDs)
host one or more spatially offset, UV-bright companions at projected separations
of 0.5 kpc ≲ d ≲ 5 kpc, with median 〈d〉 = 1.0 kpc. This fraction is even higher
when smaller spatial scales are probed at high signal-to-noise ratio: the two
most strongly lensed LRDs, A383-LRD1 and the newly discovered A68-LRD1, both have
UV-bright companions at separations of only d ∼ 0.3 kpc, below the resolution
limit of most unlensed JWST samples. We explore whether these ubiquitous red/blue
configurations may be physically linked to the formation of LRDs, in analogy with
the “synchronized pair” scenario originally proposed for direct-collapse black
hole formation. In this picture, UV radiation from the companions, with typically
modest stellar masses (M∗ ∼ 108−109 M⊙), suppresses molecular hydrogen cooling
in nearby gas, allowing nearly isothermal collapse and the formation of extremely
compact objects, such as massive black holes, supermassive stars, or quasi-stars.
Using component-resolved photometry and spectral energy distribution modeling,
we infer Lyman–Werner radiation fields of J21,LW ∼ 102.5–105 at the locations
of the red components, comparable to those required in direct-collapse models,
suggesting that the necessary photodissociation conditions are realized in many
LRD systems. This framework provides a simple and self-consistent explanation
for the extreme compactness and distinctive spectral properties of LRDs and links
long-standing theoretical models for early compact object formation directly to
a population now observed with JWST in the early Universe.'

text: Analog quantum simulators provide access to many-body dynamics beyond the
reach of classical computation. However, extracting physical insights from experimental
data is often hindered by measurement noise, limited observables, and incomplete
knowledge of the underlying microscopic model. Here, we develop a machine learning
approach based on a variational autoencoder (VAE) to analyze interference measurements
of tunnel-coupled one-dimensional Bose gases, which realize the sine-Gordon quantum
field theory. Trained in an unsupervised manner, the VAE learns a minimal latent
representation that strongly correlates with the equilibrium control parameter
of the system. Applied to nonequilibrium protocols, the latent space uncovers
signatures of frozen-in solitons following rapid cooling, and reveals anomalous
postquench dynamics not captured by conventional correlation-based methods. These
results demonstrate that generative models can extract physically interpretable
variables directly from noisy and sparse experimental data, providing complementary
probes of equilibrium and nonequilibrium physics in quantum simulators. More broadly,
our work highlights how machine learning can supplement established field-theoretical
techniques, paving the way for scalable, data-driven discovery in quantum many-body
systems.

text: 'Despite the success of mRNA therapeutics, challenges remain in optimizing
immune responses and minimizing side effects. Cell-specific antigen delivery may
help reduce required doses and improve vaccine efficacy. In this study, we report
on a targeted delivery system for mRNA to a specific subset of skin-resident antigen-presenting
cells: Langerhans cells. By functionalizing lipid nanoparticles with a langerin-specific
glycomimetic ligand, we achieve selective mRNA delivery to both murine and human
primary Langerhans cells with minimal off-target uptake, at the same time resulting
in significantly increased mRNA translation. This targeted mRNA delivery not only
enhances antigen presentation and T-cell responses but also enables dose-sparing
and superior antitumor immunity compared with conventional immunization in a B16-OVA
tumor model. Importantly, our platform’s high compatibility with various lipid
nanoparticle formulations offers a flexible and precise tool for skin-directed
mRNA delivery.'

text: Glutamate excitotoxicity is a cell death mechanism triggered by accumulation
of glutamate in the extracellular space. The α-ketoglutarate dehydrogenase complex
(αKGDHC), an enzyme of the tricarboxylic acid cycle, represents a branching point
controlling glutamate formation and its consumption as a fuel. Hence, modulation
of the activity of αKGDHC might alter the amount of glutamate available for excitotoxic
effects. To address this hypothesis, hippocampal neurons in primary co-culture
with glial cells were exposed to zero-Mg2 buffer to elicit excitotoxicity through
N-methyl-D-aspartic acid (NMDA) receptor disinhibition. Pretreatment of the cultures
with succinyl phosphonate, to inhibit αKGDHC, enhanced excitotoxity, whereas promotion
of αKGDHC activity by pretreatment with thiamine caused an opposite action. Moreover,
NMDA receptor currents – but not those mediated by α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic
acid (AMPA) receptors – were potentiated in neurons with impaired αKGDHC activity
and diminished in neurons with boosted αKGDHC activity. The sensitization of NMDA
receptors involved mGluR1 activation and was accompanied by enhanced neuronal
discharge activity, elevated basal cytosolic Ca2+ levels, and augmented Ca2+ responses
evoked by glutamate application. These results suggest that mGluR1-mediated potentiation
of NMDA receptors contributes to a mechanism by which inhibition of αKGDHC might
exacerbate glutamate excitotoxicity.

text: "Atoms and photons, two things so different but yet so alike. The former,
the building block of matter, something we learn about in school and imagine it
as some tiny marbles encircled by other tinier marbles. The latter, an electromagnetic
wave, a light particle or an excitation of the electromagnetic field. Quantum
mechanics tells us about the properties of these two entities. And even if it
sounds, looks and writes counter-intuitive, it has proven right for over a century
now.\r\n\r\nIn this work, I elaborate on how we tested the laws of quantum mechanics
and how we used them learn more about the tiny building blocks of nature and the
fields they use to talk to each other. The atoms we use, are artificial. Superconducting
qubits, small electrical circuits with quantized energy levels behave like electrons
that transition between different orbitals in an atom. One of the qubits' advantages,
is also a big disadvantage. We design the circuits' energy levels and fabricate
them in a cleanroom. This allows for arbitrary spaced energy levels but in contrast
to real atoms, prevents two superconducting qubits from being alike. Still, this
qubit platform is one of the frontrunners for future quantum computing technology
and testing fundamental physics due to their scalability.\r\n\r\nWe interface
superconducting qubits, which operate in the GHz regime, with microwave photons.
We use 3D aluminum cavities as mediators between qubits and photons. The cavities
allow for non-destructive readout of the qubit state, they shield the qubits from
noise at the qubit frequency and they give us an easy way to frequency-tune these
joint systems.\r\n\r\nWe need to operate superconducting qubits and their cavities
at millikelvin temperatures in dilution refrigerators. At higher temperatures,
superconductivity suffers and even worse, the environment is filled with thermal
noise photons. This poses a fundamental limitation on the scalability of superconducting
qubit devices. Also connecting multiple devices in different fridges does not
work over room temperature links because the microwave photons used for this purpose
will be covered in noise and the quantum information they carry, will be unusable.\r\n\r\nInfrared
photons do not suffer from this noise problem since there are close to zero thermal
noise photons at their frequencies at room temperature. We cannot simply interface
superconducting devices with optical photons due their frequency mismatch and
the destructive effect of optical photons on superconductors. Therefore, we use
microwave-to-optics transducers that allow to convert microwave photons into optical
ones and vice-versa. The transducers that we use are macroscopic electro-optic
transducers using the Pockels effect in a disk-shaped Lithium Niobate whispering
gallery mode resonator. By using a strong optical pump, photons from the two frequency
domains experience a beam-splitter interaction and get converted from one to the
other.\r\n\r\nWe measure the generated optical photons using elaborate optical
setups, optical heterodyning and single photon detectors to gain knowledge about
the qubit state or the converted microwave photons. Bridging the microwave and
the optical world allows us to take advantage of both of their strengths but it
also requires deep knowledge about both of their working principles.\r\n\r\nIn
this work, we describe two experiments that our group conducted to showcase the
opportunities that arise from interfacing superconducting qubits with optical
photons but also the pitfalls, one may encounter on the way.\r\n\r\nIn the first
experiment, we managed to all-optically read out a superconducting qubit. We show
that the assignment fidelity, the probability that a measurement of the qubit
state matches the prepared state, is close to equal for all-optical, microwave-to-optics
and conventional microwave readout. We show T1 and T2 measurements for all three
readout types and give an analysis of the noise caused by the optics. Finally,
we show that the infrared light does not affect the qubit performance in a negative
way but that the heating it causes does. This is an important insight that we
used in the next experiment.\r\n\r\nThe second experiment is the upconversion
of itinerant single microwave photons to the optical domain. We show that we can
generate single microwave photons from a qubit-cavity system. We upconvert these
single photons, measure them with a single photon detector and reconstruct their
shape. By conducting a single photon Rabi measurement, we show correlations between
the microwave and the optical domain. And by thorough signal-to-noise measurements
and noise analysis, we find that we can generate single infrared photons with
high signal-to-noise ratio 5.1 and low transducer added noise (<0.012 quanta).
We show that this measurement creates a path towards entanglement of a superconducting
qubit and an optical photon and what parameters need to be improved to achieve
it. Additionally, this experiment is a proof of principle for an on-demand infrared
single photon source. More generally, it allows to link microwave quantum technology
in general to the optical domain."

text: Superconducting qubits are a leading candidate for utility-scale quantum computing
due to their fast gate speeds and steadily decreasing error rates. The requirement
for millikelvin operating temperatures, however, creates a significant scaling
bottleneck. Modular architectures using optical fiber links could bridge separate
cryogenic nodes, but superconducting circuits do not have coherent optical transitions
and microwave-to-optical conversion has not been shown for any non-classical photon
state. In this work, we demonstrate the on-demand generation and tomographic reconstruction
of itinerant single microwave photons at 8.9 GHz from a superconducting qubit.
We upconvert this non-Gaussian state with a transducer added noise below 0.012
quanta and count the converted telecom photons at 193.4 THz with a signal-to-noise
ratio of up to 5.1$\pm$1.1. We characterize the trade-offs between throughput
and noise, and establish a viable path toward heralded entanglement distribution
and gate teleportation. Looking ahead, these results empower existing superconducting
devices to take a key role in distributed quantum technologies and heterogeneous
quantum systems.

text: The nature of little red dots (LRDs) has largely been investigated through
their continuum emission, with lines assumed to arise from a broad-line region.
In this paper, we instead use recombination lines to infer the intrinsic properties
of the central engine. Our analysis first reveals a tension between the ionizing
properties implied from Hα and He ii λ4686. The high Hα EWs require copious H-ionizing
photons, more than the bluest active galactic nucleus (AGN) ionizing spectra can
provide. In contrast, He ii emission is marginally detected, and its low EW is,
at most, consistent with the softest AGN spectra. The low He ii/Hβ (∼10−2, <20× local
AGN median) further points to an unusually soft ionizing spectrum. We extend our
analysis to dense gas envelopes (quasi-star/black-hole star) and find that hydrogen
recombination lines become optically thick and lose diagnostic power, but He ii
remains optically thin and a robust tracer. Photoionization modeling with Cloudy
rules out standard AGN accretion disk spectra. Alternative explanations include
exotic AGN with red rest-optical emission, high average optical depth (>10) from
gas/dust, and soft ionizing spectra with abundant H-ionizing photons, consistent
with, e.g., a cold accretion disk or a composite of AGN and stars. The latter
is an intriguing scenario since high hydrogen densities are highly conducive for
star formation, and nuclear star clusters are found in the vicinity of local massive
black holes. While previous studies have mostly focused on features dominated
by the absorbing hydrogen cloud, the He ii-based diagnostic proposed here represents
a crucial step toward understanding the central engine of LRDs.

Dα and add a small number of random edges to it, will typically contain a fixed

Araujo, Balogh, Krueger, Piga and Treglown and generalizes the corresponding result
for randomly perturbed graphs by Krivelevich, Kwan and Sudakov. More specifically,
we prove that there exists a constant c=c(α,Δ) such that if \r\nT is an oriented

text: "The Dean–Kawasaki equation—one of the most fundamental SPDEs of\r\nfluctuating
hydrodynamics—has been proposed as a model for density fluctuations in weakly
interacting particle systems. In its original form, it is highly\r\nsingular and
fails to be renormalizable, even by approaches such as regularity structures and
paracontrolled distributions, hindering mathematical approaches to its rigorous
justification. It has been understood recently that it is\r\nnatural to introduce
a suitable regularization, for example, by applying a formal spatial discretization
or by truncating high-frequency noise: This yields\r\nwell-posed equations that
should still precisely approximate the law of the\r\nparticle density fluctuations.\r\nIn
the present work, we prove that a regularization in the form of a formal\r\ndiscretization
of the Dean–Kawasaki equation indeed accurately describes\r\ndensity fluctuations
in systems of weakly interacting diffusing particles: We\r\nshow that, in suitable
weak metrics, the law of fluctuations as predicted by\r\nthe discretized Dean–Kawasaki
SPDE approximates the law of fluctuations\r\nof the original particle system,
up to an error that is of arbitrarily high order in\r\nthe inverse particle number
and a discretization error. In particular, the Dean–\r\nKawasaki equation provides
a means for efficient and accurate simulations of\r\ndensity fluctuations in weakly
interacting particle systems."

text: The mammalian brain organises knowledge about entities in the world and relationships
between them using cognitive maps. When forming a cognitive map, there is a necessary
trade-off between extending the map to make novel inferences, and storing a veridical
copy of past experience. However, the neural mechanisms that control this trade-off
remain unknown. Using a cross-scale approach that combines a pharmacological intervention
in humans with neural network modelling, we show that the neuromodulator noradrenaline
elicits a significant ‘spread of association’ across hippocampal cognitive maps.
This neural spread of association can be explained by changes in synaptic plasticity
that predict overgeneralisation in behaviour. Thus, elevated noradrenaline during
learning increases the ‘smoothing kernel’ for plasticity across the cognitive
map, allowing disparate memories to become linked and distorted.

text: Ultracompact binary systems, consisting of two compact objects in an orbit
$\lesssim 0.5 {\rm R}_\odot$, should exhibit measurable rates of orbital period
change ($\dot{P} \ne 0$) due to the emission of gravitational waves (GWs). Measurements
of $\dot{P}$ have so far been limited to the shortest-period ultracompact binaries
($\lesssim 20$ min). Among the AM CVn-type subclass, several works have proposed
the presence of extra angular momentum loss beyond GW emission, with magnetic
braking being a widely discussed mechanism. If present, this magnetic braking
would dominate the angular momentum loss of AM CVn-type binaries with orbital
periods $\gtrsim 30$ min. In this work, we present a long-term eclipse timing
study of two AM CVn-type binaries, YZ LMi and Gaia14aae, with respective orbital
periods of 28.3 min and 49.7 min and continuous observations since 2006 and 2015.
Both systems show $\dot{P}$ consistent with zero within $2\sigma$. Their $3\sigma$
upper limits are $1.1 \times 10^{-13}\, {\rm s \, s}^{-1}$ and $9.7 \times 10^{-14}\,
{\rm s \, s}^{-1}$, respectively. These non-detections are most simply explained
by a scenario in which secular angular momentum loss is not substantially stronger
than GW emission at all orbital periods, but is combined with deviations from
the secular $\dot{P}$ whose time-scales span decades but whose amplitude is $\lesssim
10^{-13}\, {\rm s \, s}^{-1}$. Our non-detections of $\dot{P}$ represent a limit
on the strength of any enhanced angular momentum loss beyond pure GW emission.

text: We investigate the nature and spectroscopic diversity of early galaxies from
a sample of 41 sources at $z\geqslant 10$ with James Webb Space Telescope (JWST)/NIRSpec
prism observations. We compare the properties of strong ultraviolet (UV) line
emitters, traced by intense C iv emission, with those of more ‘typical’ sources
with weak or undetected C iv. The more typical (or ‘C iv-weak’) sources reveal
significant scatter in their C iii] line strengths, UV continuum slopes, and physical
sizes, spanning C iii] equivalent widths (EWs) of $\sim$1–51 Å, UV slopes of $\beta
\sim -1.6$ to $-2.6$, and half-light radii of $\sim$50–1000 pc. In contrast, C iv-strong
sources occupy the tail of these distributions, with C iii] EWs of 16–51 Å, UV
slopes $\beta \lesssim -2.5$, compact morphologies ($r_{\rm 50} \lesssim 100$ pc),
and elevated star formation surface densities ($\Sigma _{\rm SFR} \gtrsim 100\,
M_\odot \, \mathrm{yr}^{-1}\, \mathrm{kpc}^{-2}$). These properties suggest concentrated
starbursts that temporarily outshine the host galaxy. Comparing average properties
from composite spectra, we find the diversity of the sample is primarily driven
by bursty star formation on very short time-scales ($\le$3 Myr), with strong C iv
emitters observed at the apex of the bursts and sources devoid of emission lines
during relative inactivity. An apparent association between strong C iv and enhanced
nitrogen abundance suggests both may be modulated by the same duty cycle, reflecting
a generic mode of star formation. We show that active galactic nuclei are unlikely
to contribute significantly to this duty cycle based on UV line diagnostics and
photoionization models. Our results support a picture whereby brief bursts and
lulls can explain the spectral diversity and early growth of bright galaxies in
the first 500 Myr.

text: Cell extrusion is an essential mechanism for controlling cell density in epithelial
tissues. Another essential element of epithelia is curvature, which is required
to achieve complex shapes, like in the lung or intestine. Here, we introduce a
three-dimensional bubbly vertex model to study the interplay between extrusion
and curvature. We find a generic cellular bulging instability at topological defects,
which is much stronger than for standard vertex models. Analyzing cell shapes
in three-dimensional imaging data of spherical mouse colon organoids, we infer
that pentagonal cells have an increased basal interfacial tension, suggesting
that cells at topological defects react to the different force conditions. Using
the bubbly vertex model, we show that such basal tensions stabilize against the
predicted instability and result in better cell shape control than tissue-scale
mechanisms such as lumen pressure and spontaneous curvature. Our theory suggests
that epithelial curvature naturally leads to bulged and extrusionlike cell shapes
because the interfacial curvature of individual cells at the defects strongly
amplifies buckling effected by tissue-scale topological defects in elastic sheets.
Our results highlight the complex interplay of forces across scales in three-dimensional
tissue organization.
