text: We solve a problem of Dujmović and Wood (2007) by showing that a complete
convex geometric graph on n vertices cannot be decomposed into fewer than n-1
star-forests, each consisting of noncrossing edges. This bound is clearly tight.
We also discuss similar questions for abstract graphs.

text: We study turn-based stochastic zero-sum games with lexicographic preferences
over objectives. Stochastic games are standard models in control, verification,
and synthesis of stochastic reactive systems that exhibit both randomness as well
as controllable and adversarial non-determinism. Lexicographic order allows one
to consider multiple objectives with a strict preference order. To the best of
our knowledge, stochastic games with lexicographic objectives have not been studied
before. For a mixture of reachability and safety objectives, we show that deterministic
lexicographically optimal strategies exist and memory is only required to remember
the already satisfied and violated objectives. For a constant number of objectives,
we show that the relevant decision problem is in NP∩coNP, matching the current
known bound for single objectives; and in general the decision problem is PSPACE-hard
and can be solved in NEXPTIME∩coNEXPTIME. We present an algorithm that computes
the lexicographically optimal strategies via a reduction to the computation of
optimal strategies in a sequence of single-objectives games. For omega-regular
objectives, we restrict our analysis to one-player games, also known as Markov
decision processes. We show that lexicographically optimal strategies exist and
need either randomization or finite memory. We present an algorithm that solves
the relevant decision problem in polynomial time. We have implemented our algorithms
and report experimental results on various case studies.

text: Superconductor/semiconductor hybrid devices have attracted increasing interest
in the past years. Superconducting electronics aims to complement semiconductor
technology, while hybrid architectures are at the forefront of new ideas such
as topological superconductivity and protected qubits. In this work, we engineer
the induced superconductivity in two-dimensional germanium hole gas by varying
the distance between the quantum well and the aluminum. We demonstrate a hard
superconducting gap and realize an electrically and flux tunable superconducting
diode using a superconducting quantum interference device (SQUID). This allows
to tune the current phase relation (CPR), to a regime where single Cooper pair
tunneling is suppressed, creating a sin(2y) CPR. Shapiro experiments complement
this interpretation and the microwave drive allows to create a diode with ≈ 100%
efficiency. The reported results open up the path towards integration of spin
qubit devices, microwave resonators and (protected) superconducting qubits on the
same silicon technology compatible platform.

text: It is widely believed that information storage in neuronal circuits involves
nanoscopic structural changes at synapses, resulting in the formation of synaptic
engrams. However, direct evidence for this hypothesis is lacking. To test this
conjecture, we combined chemical potentiation, functional analysis by paired pre-postsynaptic
recordings, and structural analysis by electron microscopy (EM) and freeze-fracture
replica labeling (FRL) at the rodent hippocampal mossy fiber synapse, a key synapse
in the trisynaptic circuit of the hippocampus. Biophysical analysis of synaptic
transmission revealed that forskolin-induced chemical potentiation increased the
readily releasable vesicle pool size and vesicular release probability by 146%
and 49%, respectively. Structural analysis of mossy fiber synapses by EM and FRL
demonstrated an increase in the number of vesicles close to the plasma membrane
and the number of clusters of the priming protein Munc13-1, indicating an increase
in the number of both docked and primed vesicles. Furthermore, FRL analysis revealed
a significant reduction of the distance between Munc13-1 and CaV2.1 Ca2+ channels,
suggesting reconfiguration of the channel-vesicle coupling nanotopography. Our
results indicate that presynaptic plasticity is associated with structural reorganization
of active zones. We propose that changes in potential nanoscopic organization
at synaptic vesicle release sites may be correlates of learning and memory at
a plastic central synapse.

text: It is widely believed that information storage in neuronal circuits involves
nanoscopic structural changes at synapses, resulting in the formation of synaptic
engrams. However, direct evidence for this hypothesis is lacking. To test this
conjecture, we combined chemical potentiation, functional analysis by paired pre-postsynaptic
recordings, and structural analysis by electron microscopy (EM) and freeze-fracture
replica labeling (FRL) at the murine hippocampal mossy fiber synapse, a key synapse
in the trisynaptic circuit of the hippocampus. Biophysical analysis of synaptic
transmission revealed that forskolin-induced chemical potentiation increased the
readily releasable vesicle pool size and vesicular release probability by 146%
and 49%, respectively. Structural analysis of mossy fiber synapses by EM and FRL
demonstrated an increase in the number of vesicles close to the plasma membrane
and the number of clusters of the priming protein Munc13-1, indicating an increase
in the number of both docked and primed vesicles. Furthermore, FRL analysis revealed
a significant reduction of the distance between Munc13-1 and CaV2.1 Ca2+ channels,
suggesting reconfiguration of the channel-vesicle coupling nanotopography. Our
results indicate that presynaptic plasticity is associated with structural reorganization
of active zones. We propose that changes in potential nanoscopic organization
at synaptic vesicle release sites may be correlates of learning and memory at
a plastic central synapse.

text: Amide-proton-detected magic-angle-spinning NMR of deuterated proteins has
become a main technique in NMR-based structural biology. In standard deuteration
protocols that rely on D2O-based culture media, non-exchangeable amide sites remain
deuterated, making these sites unobservable. Here we demonstrate that proteins
produced with a H2O-based culture medium doped with deuterated cell lysate allow
scientists to overcome this “reprotonation bottleneck” while retaining a high
level of deuteration (ca. 80 %) and narrow linewidths. We quantified coherence
lifetimes of several proteins prepared with this labeling pattern over a range
of magic-angle-spinning (MAS) frequencies (40–100 kHz). We demonstrate that under
commonly used conditions (50–60 kHz MAS), the amide 1H linewidths with our labeling
approach are comparable to those of perdeuterated proteins and better than those
of protonated samples at 100 kHz. For three proteins in the 33–50 kDa size range,
many previously unobserved amides become visible. We report how to prepare the
deuterated cell lysate for our approach from fractions of perdeuterated cultures
which are usually discarded, and we show that such media can be used identically
to commercial media. The residual protonation of Hα sites allows for well-resolved
Hα-detected spectra and Hα resonance assignment, exemplified by the de novo assignment
of 168 Hα sites in a 39 kDa protein. The approach based on this H2O/cell-lysate
deuteration and MAS frequencies compatible with 1.3 or 1.9 mm rotors presents
a strong sensitivity benefit over 0.7 mm 100 kHz MAS experiments.

text: The GNOM (GN) Guanine nucleotide Exchange Factor for ARF small GTPases (ARF-GEF)
is among the best studied trafficking regulators in plants, playing crucial and
unique developmental roles in patterning and polarity. The current models place
GN at the Golgi apparatus (GA), where it mediates secretion/recycling, and at
the plasma membrane (PM) presumably contributing to clathrin-mediated endocytosis
(CME). The mechanistic basis of the developmental function of GN, distinct from
the other ARF-GEFs including its closest homologue GNOM-LIKE1 (GNL1), remains
elusive. Insights from this study largely extend the current notions of GN function.
We show that GN, but not GNL1, localizes to the cell periphery at long-lived structures
distinct from clathrin-coated pits, while CME and secretion proceed normally in
gn knockouts. The functional GN mutant variant GNfewerroots,
absent from the GA, suggests that the cell periphery is the major site of GN action
responsible for its developmental function. Following inhibition by Brefeldin
A, GN, but not GNL1, relocates to the PM likely on exocytic vesicles, suggesting
selective molecular associations en route to the cell periphery. A study of GN-GNL1
chimeric ARF-GEFs indicates that all GN domains contribute to the specific GN
function in a partially redundant manner. Together, this study offers significant
steps toward the elucidation of the mechanism underlying unique cellular and development
functions of GNOM.

text: Predicting the outcomes of adaptation is a major goal of evolutionary biology.
When temporal changes in the environment mirror spatial gradients, it opens up
the potential for predicting the course of adaptive evolution over time based
on patterns of spatial genetic and phenotypic variation. We assessed this approach
in a 30-year transplant experiment in the intertidal snail Littorina saxatilis.
In 1992, snails were transplanted from a predation-dominated environment to one
dominated by wave action. On the basis of spatial patterns, we predicted transitions
in shell size and morphology, allele frequencies at positions throughout the genome,
and chromosomal rearrangement frequencies. Observed changes closely agreed with
predictions and transformation was both dramatic and rapid. Hence, adaptation
can be predicted from knowledge of the phenotypic and genetic variation among
populations.

text: Gate-tunable transmons (gatemons) employing semiconductor Josephson junctions
have recently emerged as building blocks for hybrid quantum circuits. In this
study, we present a gatemon fabricated in planar Germanium. We induce superconductivity
in a two-dimensional hole gas by evaporating aluminum atop a thin spacer, which
separates the superconductor from the Ge quantum well. The Josephson junction
is then integrated into an Xmon circuit and capacitively coupled to a transmission
line resonator. We showcase the qubit tunability in a broad frequency range with
resonator and two-tone spectroscopy. Time-domain characterizations reveal energy
relaxation and coherence times up to 75 ns. Our results, combined with the recent
advances in the spin qubit field, pave the way towards novel hybrid and protected
qubits in a group IV, CMOS-compatible material.

text: We present a theory describing the interaction of structured light, such as
light carrying orbital angular momentum, with molecules. The light-matter interaction
Hamiltonian we derive is expressed through couplings between spherical gradients
of the electric field and the (transition) electric multipole moments of a particle
of any nontrivial rotation point group. Our model can therefore accommodate an
arbitrary complexity of the molecular and electric field structure, and it can
be straightforwardly extended to atoms or nanostructures. Applying this framework
to rovibrational spectroscopy of molecules, we uncover the general mechanism of
angular momentum exchange between the spin and orbital angular momenta of light,
molecular rotation, and its center-of-mass motion. We show that the nonzero vorticity
of Laguerre-Gaussian beams can strongly enhance certain rovibrational transitions
that are considered forbidden in the case of nonhelical light. We discuss the
experimental requirements for the observation of these forbidden transitions in
state-of-the-art spatially resolved spectroscopy measurements.

text: "The new era of Ge has opened up new possibilities in quantum computing. The
maturity of Ge\r\nspin qubits is unquestioned, while hybrid semiconductor-superconductor
Ge circuits are on track\r\nto enter the game. Gate-tunable transmons (gatemons)
employing semiconductor Josephson\r\njunctions have recently emerged as building
blocks for such hybrid quantum circuits. In this\r\nthesis, we present a gatemon
fabricated in planar Germanium. We induce superconductivity\r\nin a two-dimensional
hole gas by evaporating aluminum atop a thin spacer, which separates\r\nthe superconductor
from the Ge quantum well. The Josephson junction is then integrated\r\ninto an
Xmon circuit and capacitively coupled to a transmission line resonator. We showcase\r\nthe
qubit tunability in a broad frequency range with resonator and two-tone spectroscopy.\r\nTime-domain
characterizations reveal energy relaxation and coherence times up to 75 ns. Our\r\nresults,
combined with the recent advances in the spin qubit field, pave the way towards
novel\r\nhybrid and protected qubits in a group IV, CMOS-compatible material."

text: This is the supplementary data for the paper titled "Single-nucleus atlas
of the Artemia female reproductive system suggests germline repression of the
Z chromosome", where we described the generation and analysis of single-nucleus
expression and chromatin-accessibility data from the female reproductive system
of Artemia franciscana. We compared our dataset to the published Drosophila single-nucleus
data (over 400 million years of divergence) and highlighted the extreme conservation
of several of the molecular pathways of oogenesis and meiosis. We found evidence
of global transcriptional quiescence and chromatin condensation in late germ cells,
highlighting the conserved role of this repressive stage in arthropod oogenesis.
Additionally, we explored the expression patterns of the ZW sex chromosomes during
oogenesis. Our data shows that the Z-chromosome is consistently downregulated
in germline cells. While this is partly driven by a lack of dosage compensation
in the germline, a subset of cells show stronger repression of the Z chromosome.

text: We present a framework for the end-to-end optimization of metasurface imaging
systems that reconstruct targets using compressed sensing, a technique for solving
underdetermined imaging problems when the target object exhibits sparsity (e.g.,
the object can be described by a small number of nonzero values, but the positions
of these values are unknown). We nest an iterative, unapproximated compressed
sensing reconstruction algorithm into our end-to-end optimization pipeline, resulting
in an interpretable, data-efficient method for maximally leveraging metaoptics
to exploit object sparsity. We apply our framework to super-resolution imaging
and high-resolution depth imaging with a phase-change material. In both situations,
our end-to-end framework effectively optimizes metasurface structures for compressed
sensing recovery, automatically balancing a number of complicated design considerations
to select an imaging measurement matrix from a complex, physically constrained
manifold with millions of dimensions. The optimized metasurface imaging systems
are robust to noise, significantly improving over random scattering surfaces and
approaching the ideal compressed sensing performance of a Gaussian matrix, showing
how a physical metasurface system can demonstrably approach the mathematical limits
of compressed sensing.

text: 'Scintillation materials convert high-energy radiation to optical light through
a complex multistage process. The last stage of the process is spontaneous light
emission, which usually governs and limits the scintillator emission rate and
light yield. For decades, scintillator research focused on developing faster-emitting
materials or external photonic coatings for improving light yields. Here, we experimentally
demonstrate a fundamentally different approach: enhancing the scintillation rate
and yield via the Purcell effect, utilizing optical environment engineering to
boost spontaneous emission. This enhancement is universally applicable to any
scintillating material and dopant when the material’s nanoscale geometry is engineered.
We design a thin multilayer nanophotonic scintillator, demonstrating Purcell-enhanced
scintillation with 50% enhancement in emission rate and 80% enhancement in light
yield. The emission is robust to fabrication disorder, further highlighting its
potential for x-ray applications. Our results show prospects for bridging nanophotonics
and scintillator science toward reduced radiation dosage and increased resolution
for high-energy particle detection.'

text: 'A central challenge in the emerging field of free-electron quantum optics
is to achieve strong quantum interaction and single-photon nonlinearity between
a flying free electron and a photonic mode. Existing schemes are intrinsically
limited by electron diffraction, which puts an upper bound on the interaction
length and, therefore, on the strength of quantum coupling and nonlinearity. Here,
we propose “free-electron fibers”: effectively one-dimensional photonic systems
where free electrons copropagate with two guided modes. The first mode applies
a ponderomotive trap to the free electron, removing the limitations due to electron
diffraction. The second mode strongly couples to the guided free electron with
an enhanced coupling that is orders of magnitude larger than previous designs.
The extended interaction lengths enabled by our scheme allow for strong single-photon
nonlinearities mediated by free electrons. We predict novel quantum effects in
our system such as deterministic single-photon emission and nonlinear multimode
dynamics. Our proposal paves the way toward the realization of heralded macroscopic
nonclassical light generation, deterministic single-photon sources, and quantum
gates controlled by free-electron–photon interactions.'

text: Probabilistic machine learning utilizes controllable sources of randomness
to encode uncertainty and enable statistical modeling. Harnessing the pure randomness
of quantum vacuum noise, which stems from fluctuating electromagnetic fields,
has shown promise for high speed and energy-efficient stochastic photonic elements.
Nevertheless, photonic computing hardware which can control these stochastic elements
to program probabilistic machine learning algorithms has been limited. Here, we
implement a photonic probabilistic computer consisting of a controllable stochastic
photonic element – a photonic probabilistic neuron (PPN). Our PPN is implemented
in a bistable optical parametric oscillator (OPO) with vacuum-level injected bias
fields. We then program a measurement-and-feedback loop for time-multiplexed PPNs
with electronic processors (FPGA or GPU) to solve certain probabilistic machine
learning tasks. We showcase probabilistic inference and image generation of MNIST-handwritten
digits, which are representative examples of discriminative and generative models.
In both implementations, quantum vacuum noise is used as a random seed to encode
classification uncertainty or probabilistic generation of samples. In addition,
we propose a path towards an all-optical probabilistic computing platform, with
an estimated sampling rate of ~1 Gbps and energy consumption of ~5 fJ/MAC. Our

text: Multimode quantum light is enticing for several applications, spanning imaging,
spectroscopy, communication, and more. Parametric nonlinear processes have been
vital in realizing squeezed and other quantum states of light. However, most work
exploiting these processes has focused on generating multimode squeezed vacua
and squeezing in mode superpositions (supermodes). Bright squeezing in multiple
discrete frequency modes, if realized, could unlock novel applications in quantum-enhanced
spectroscopy and optical quantum computing. Here, we show how dissipation engineering
of a multimode nonlinear cavity with cascaded three-wave-mixing processes allows
us to shape above-threshold frequency combs that feature strong single-mode output
amplitude noise squeezing over 10 dB below the shot-noise limit, tunable across
the comb. In addition, we demonstrate squeezing for multiple discrete frequency
modes above threshold. This bright squeezing arises from enhancement of the (noiseless)
nonlinear rate relative to decay rates in the system due to the cascaded generation
of photons in a single idler “bath” mode. A natural consequence of the strong
nonlinear coupling in our system is the creation of an effective cavity in the
synthetic frequency dimension that sustains Bloch oscillations in the modal energy
distribution. Bloch mode engineering could provide an opportunity to better control
nonlinear energy flow in the synthetic frequency dimension, with exciting applications
in quantum random walks and topological photonics. Lastly, we show evidence of
long-range correlations in amplitude noise between discrete frequency modes, enabling
long-range entanglement in a synthetic frequency dimension and providing a new
resource for quantum communication.
