text: Rational design strategies for self-assembly require a detailed understanding
of both the equilibrium state and the assembly kinetics. While the former is starting
to be well understood, the latter remains a major theoretical challenge, especially
in programmable systems and the so-called semi-addressable regime, where binding
is often nondeterministic and the formation of off-target structures negatively
influences the assembly. Here, we show that it is possible to simultaneously sculpt
the assembly outcome and the assembly kinetics through the underexplored design
space of binding energies and particle concentrations. By formulating the assembly
process as a complex reaction network, we calculate and optimize the tradeoff
between assembly speed and quality and show that parameter optimization can speed
up assembly by many orders of magnitude without lowering the yield of the target
structure. Although the exact speedup varies from design to design, we find the
largest speedups for nondeterministic systems where unoptimized assembly is the
slowest, sometimes even making them assemble faster than optimized, fully addressable
designs. Therefore, these results not only solve a key challenge in semi-addressable
self-assembly but further emphasize the utility of semi-addressability, where
designs have the potential to be faster as well as cheaper (fewer particle species)
and better (higher yield). More broadly, our results highlight the importance
of parameter optimization in programmable self-assembly and provide practical
tools for simultaneous optimization of kinetics and yield in a wide range of systems.

text: Three-dimensional (3D) crystals offer a route to scaling up trapped-ion systems
for quantum sensing and quantum simulation applications; however, engineering
coherent spin-motion couplings and effective spin-spin interactions in large crystals
poses technical challenges associated with decoherence and prolonged timescales
to generate appreciable entanglement. Here, we explore the possibility of speeding
up these interactions in 3D crystals via parametric amplification. For this purpose,
we derive a general Hamiltonian for the parametric amplification of spin-motion
coupling that is broadly applicable to normal modes with motion transverse to
or along the spatial extent of the crystal. Unlike in lower-dimensional crystals,
we find that the ability to faithfully (uniformly) amplify the spin-spin interactions
in 3D crystals depends on the physical implementation of the spin-motion coupling.
We consider the light-shift gate, and the so-called phase-insensitive and phase-sensitive
Mølmer-Sørensen (MS) gates, and we find that only the phase-sensitive MS gate
can be faithfully amplified in general 3D crystals. We discuss a situation where
nonuniform amplification can be advantageous. We also reconsider the effect of
counter-rotating terms on parametric amplification and find that they are not
as detrimental as previous studies suggest.

text: Galaxies exhibit a tight correlation between their star formation rate (SFR)
and stellar mass over a wide redshift range known as the star-forming main sequence
(SFMS). With JWST, the SFMS can now be investigated at high redshifts down to
masses of ∼106 M⊙, using sensitive star formation rate tracers such as the Hα
emission, which allow us to probe the variability in the star formation histories.
We present inferences of the SFMS based on 316 Hα-selected galaxies at z ∼ 4 − 5
with log(M★/M⊙) = 6.4 − 10.6. These galaxies were identified behind the Abell
2744 lensing cluster with NIRCam grism spectroscopy from the survey All the Little
Things (ALT). At face value, our data suggest a shallow slope in the SFMS (SFR ∝ M★α,
with α = 0.45). After we corrected this for the Hα-flux limited nature of our
survey using a Bayesian framework, the slope steepened to α = 0.59+0.10−0.09,
whereas current data on their own are inconclusive on the mass dependence of the
scatter. These slopes differ significantly from the slope of ∼1 that is expected
from the observed evolution of the galaxy stellar mass function and from simulations.
When we fixed the slope to α = 1, we found evidence for a decreasing intrinsic
scatter with stellar mass (from ∼0.5 dex at M★ = 108 M⊙ to 0.4 dex at M★ = 1010
M⊙). This difference might be explained by a (combination of) luminosity-dependent
SFR(Hα) calibration, a population of (mini)-quenched low-mass galaxies, or underestimated
dust attenuation in high-mass galaxies. Future deep observations with different
facilities can quantify these processes, which will enable us to achieve better
insights into the variability of the star formation histories.

text: "Terahertz (THz) spectroscopy is a powerful probe of low-energy excitations
in complex materials. Extending it into the nonlinear regime broadens its scope
and can provide valuable insight into interactions among these modes. However,
interpreting nonlinear spectra is challenging because resonant features in this
case do not always reflect intrinsic material dynamics. Here, we study nonlinear
THz-induced Kerr effect in a generic material LaAlO3. After detailed analysis
of temporal oscillations of the Kerr signal, we identify an \U0001D438\U0001D454
Raman mode at 1.1 THz excited through a two-photon process, while two additional
peaks (0.86 and 0.36 THz) arise from phase matching of the near-infrared probe
beam with co- and counterpropagating THz pump fields, mediated by off-resonant
electronic hyperpolarizability. These results demonstrate the crucial role of
kinematic effects in shaping THz-induced Kerr response and establish a framework
for interpreting nonlinear spectroscopies in complex materials."

text: Controlling the size and shape of assembled structures is a fundamental challenge
in self-assembly and is highly relevant in material design and biology. Here,
we show that specific but promiscuous short-range binding interactions make it
possible to economically assemble linear filaments of user-defined length. Our
approach leads to independent control over the mean and width of the filament
size distribution and allows us to smoothly explore design trade-offs between
assembly quality (spread in size) and cost (number of particle species). We employ
a simple hierarchical assembly protocol to minimize assembly times and show that
multiple stages of hierarchy make it possible to extend our approach to the assembly
of higher-dimensional structures. Our work provides a conceptually simple solution
to size control that is applicable to a broad range of systems, from DNA nanoparticles
to supramolecular polymers and beyond.

text: Insulating oxides are among the most abundant solid materials in the universe1,2,3.
Of the many ways in which they influence natural phenomena, perhaps the most consequential
is their capacity to transfer electrical charge during contact4,5,6,7,8,9,10—which
occurs even between samples of the same oxide—yet the symmetry-breaking parameter
that causes this remains unidentified11,12. Here we show that adventitious carbonaceous
molecules adsorbed from the environment are the symmetry-breaking factor in same-material
oxide contact electrification (CE). We use acoustic levitation to measure charge
exchange between a sphere and a plate composed of identical amorphous silicon
dioxide (SiO2). Although charging polarity is random for co-prepared samples,
we control it with baking or plasma treatment. Observing the charge-exchange relaxation
afterwards, we see dynamics over a timescale of hours and connect this directly
to the presence of adventitious carbon with time-of-flight mass spectrometry,
low-energy ion scattering and infrared spectroscopy. Going further, we confirm
that adventitious carbon can even determine charge exchange among different oxides.
Our results identify the symmetry-breaking parameter that causes insulating oxides
to exchange charge in settings ranging from desert sands4 to volcanic plumes5,6,
while simultaneously highlighting an overlooked factor in CE more broadly.

text: "Blockchains enable distributed consensus in permissionless settings, where
participants\r\nare unknown, dynamically changing, and do not trust each other.
While Bitcoin,\r\nbased on Proof-of-Work (PoW), was the first protocol in this
model, significant\r\nresearch has focused on permissionless protocols using alternative
physical resources,\r\nspecifically Proof-of-Space (PoSpace) and Verifiable Delay
Functions (VDFs). This\r\nthesis investigates the theoretical limits and design
space of longest-chain protocols in\r\nthe fully permissionless and dynamically
available settings using these three resources.\r\nFirst, we address the feasibility
of blockchains relying solely on storage as a resource.\r\nWe prove a fundamental
impossibility result: there exists no secure longest-chain\r\nprotocol based exclusively
on Proof-of-Space in the fully permissionless or dynamically\r\navailable settings.
Further, we quantify the adversarial capabilities required to execute\r\na double-spend
attack. Our result formally justifies the necessity of coupling PoSpace\r\nwith
time-dependent primitives (such as VDFs) or to move to less permissive settings\r\n(quasi-permissionless
or permissioned) to ensure security.\r\nSecond, we generalize Nakamoto-like heaviest
chain consensus to protocols utilizing\r\ncombinations of multiple physical resources.
We analyze chain selection rules governed\r\nby a weight function Γ(S, V,W), which
assigns weight to blocks based on recorded\r\nSpace (S), VDF speed (V ), and Work
(W). We provide a complete classification\r\nof secure weight functions, proving
that a weight function is secure against private\r\ndouble-spend attacks if and
only if it is homogeneous in the timed resources (V,W)\r\nand sub-homogeneous
in S. This framework unifies existing protocols like Bitcoin and\r\nChia under
a single theoretical model and provides a powerful tool for designing new\r\nlongest-chain
blockchains from a mix of physical resources."

text: Structural and functional differences between brain hemispheres are a common
feature of animal nervous systems with reduced bilateral asymmetry often linked
to impaired cognitive performance. How neuronal left-right asymmetry is initiated
and integrated into a bilaterally symmetrical ground pattern is poorly understood.
Here, we show that the directional asymmetry of a Drosophila central brain circuit
originates from axonal interactions of two types of bilateral pioneer neurons.
Subsequent recruitment of neighboring neurons into the asymmetric neuropil primordium
results in hemisphere-specific microcircuits. Circuit lateralization requires
dynamic expression of the cell adhesion molecule Fasciclin 2 to maintain structural
plasticity in axonal remodeling. Reduced circuit asymmetry following cell type–specific
Fasciclin 2 manipulation affects adult brain function. These results reveal an
unexpected degree of developmental plasticity of late-born Drosophila neurons
in the formation of a circuit node via the lateralized recruitment of symmetric
circuit components.

text: In calculus, l'Hopital's rule provides a simple way to evaluate the limits
of quotient functions when both the numerator and denominator vanish. But what
happens when we move beyond real functions on a real interval? In this article,
we study when the quotient of two complex-valued functions in higher dimension
can be defined continuously at the points where both functions vanish. Surprisingly,
the answer is far subtler than in the real-valued setting. We provide a complete
characterization for the continuity of the quotient function. We also point out
why extending this result to smoother quotients remains an intriguing challenge.

text: We present symplectic structures on the shape space of unparameterized space
curves that generalize the classical Marsden–Weinstein structure. Our method integrates
the Liouville 1-form of the Marsden–Weinstein structure with Riemannian structures
that have been introduced in mathematical shape analysis. We also derive Hamiltonian
vector fields for several classical Hamiltonian functions with respect to these
new symplectic structures.

text: Reactive oxygen species (ROS) have been implicated in multiple signaling processes
in plants, but the underlying mechanisms and roles remain enigmatic. In this study,
we developed a method of live imaging of apoplastic ROS at the root surface. Distinct
signals, including auxin, extracellular adenosine triphosphate, and rapid alkalinization
factor 1 peptide, induce cytosolic calcium transients and apoplastic ROS bursts.
Genetic and optogenetic manipulations of Arabidopsis identified calcium transients
as necessary and sufficient for ROS bursts through activation of reduced nicotinamide
adenine dinucleotide phosphate (NADPH) oxidases RBOHC and RBOHF. Apoplastic ROS
bursts are not required, but they do limit gravity-induced root bending. Root
bending is sensed by the stretch-activated calcium channel MCA1, leading to NADPH
oxidase activation. The resulting ROS production stiffens cell walls to facilitate
soil penetration. Apoplastic ROS thus provides a means to balance tissue flexibility
and stiffness to navigate soil.

text: "Colloidal fluids can exhibit complex phase behavior and determining phase
diagrams via experiments or computer simulations can be laborious. We demonstrate
that the dispersion relation ω(k), obtained from dynamical density functional
theory for the uniform density system, is a highly versatile tool for predicting
where in the phase diagram complex crystals form. The sign of ω(k) determines
whether density modes with wave number k grow or decay over time. We demonstrate
the predictive power by investigating the complex phase behavior of particles
interacting via core-shoulder pair potentials. With complementary Monte Carlo
simulations, we show that regions of the phase diagram where ωðkÞ has one or several
unstable (growing) wave numbers are also where crystalline phases occur. Going
further, by tuning these\r\nunstable wave numbers via the interaction-potential
and state-point parameters, we design systems with quasicrystals in the phase
diagram. We identify a system with a certain shoulder range exhibiting at least
ten different phases. Our general approach accelerates considerably the mapping
of complex phase diagrams, crucial for the design of new materials."

text: Pyridyl motifs equipped with N-substituents can be powerful ligands for catalysis,
yet their broader adoption is limited by the lack of a practical method to prepare
these scaffolds. We report a modular, robust, and versatile Buchwald–Hartwig amination
protocol that enables the rapid synthesis of bipyridine, phenanthroline, terpyridine,
and pybox ligands bearing dialkylamine, diarylamine, and heteroaromatic N-substituents.
These conditions streamline ligand library synthesis and will facilitate systematic
studies in catalysis and related applications.

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: A defining feature of quantum many-body systems is the exponential scaling
of the Hilbert space with the number of degrees of freedom. This exponential complexity
naïvely renders a complete state characterization, for instance via the complete
set of bipartite Renyi entropies for all disjoint regions, a challenging task.
Recently, a compact way of storing subregions' purities by encoding them as amplitudes
of a fictitious quantum wave function, known as entanglement feature, was proposed.
Notably, the entanglement feature can be a simple object even for highly entangled
quantum states. However the complexity and practical usage of the entanglement
feature for general quantum states has not been explored. In this work, we demonstrate
that the entanglement feature can be efficiently learned using only a polynomial
amount of samples in the number of degrees of freedom through the so-called tensor
cross interpolation (TCI) algorithm, assuming it is expressible as a finite bond
dimension MPS. We benchmark this learning process on Haar and random MPS states,
confirming analytic expectations. Applying the TCI algorithm to quantum eigenstates
of various one dimensional quantum systems, we identify cases where eigenstates
have entanglement feature learnable with TCI. We conclude with possible applications
of the learned entanglement feature, such as quantifying the distance between
different entanglement patterns and finding the optimal one-dimensional ordering
of physical indices in a given state, highlighting the potential utility of the
proposed purity interpolation method.

text: 'The import of proteins into mitochondria poses fundamental mechanistic challenges:
aggregation-prone precursor proteins must be maintained in aqueous compartments
and threaded through narrow pores without becoming stuck or mislocalized. Recent
evidence from mitochondrial protein import studies and other chaperone systems
underscores the critical role of dynamics in balancing sufficiently tight binding,
promiscuity, specificity, and release. Dynamic binding of client precursor proteins
to import machinery components arises naturally from the avidity of their interactions.
Conformational entropy enhances their stability, while the multivalent nature
of these interactions ensures that client transfer to downstream insertases occurs
without a substantial energy barrier. Here, we discuss this emerging paradigm
of dynamic protein handling, using examples where dynamic structures have been
resolved and highlight outstanding questions.'

text: The cerebral cortex consists of immense numbers of neuronal and glial cell-types
derived from radial glial progenitor (RGP) cells. How RGPs generate appropriate
quantities of distinct cortical cell-types to safeguard a brain of correct size,
is not well understood. However, genetic aberration in human, including mutations
in PTEN, lead to cortical malformation such as macrocephaly, albeit with unknown
etiology. Here we utilized Mosaic Analysis with Double Markers (MADM)-based clonal
analysis and single cell phenotyping to decipher the role of Pten in neurogenic
and gliogenic RGP lineage progression during cortical ontogeny. While neurogenic
RGP lineage progression and projection neuron production was moderately altered
in the absence of Pten, cortical astrocyte production was drastically increased.
Through genetic epistasis experiments we show that the loss of Pten uncouples
astrocyte generation from essential growth factor signaling hubs, funneling into
MAPK. Collectively, our results suggest that Pten regulates RGP lineage progression
with distinct sequential functions in cortical projection neurogenesis and astrocyte
production to ensure the emergence of a correctly-sized cerebral cortex.

text: For Hamiltonian actions of semidirect products G = FxH, we study 2-cocycles
arising from residual Hamiltonian actions of F on Hamiltonian reductions for H.
The motivation comes from the study of Teichmüller spaces for surfaces with boundary,
which carry Hamiltonian actions of the Virasoro algebra. In this paper, we give
a general setup for the problem, and we suggest an easier way to obtain the Gelfand-Fuchs
2-cocycles for Hamiltonian actions on Teichmüller spaces.
