  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: Robust Markov Decision Processes (RMDPs) generalize classical MDPs that consider
    uncertainties in transition probabilities by defining a set of possible transition
    functions. An objective is a set of runs (or infinite trajectories) of the RMDP,
    and the value for an objective is the maximal probability that the agent can guarantee
    against the adversarial environment. We consider (a) reachability objectives,
    where given a target set of states, the goal is to eventually arrive at one of
    them; and (b) parity objectives, which are a canonical representation for ω-regular
    objectives. The qualitative analysis problem asks whether the objective can be
    ensured with probability 1. In this work, we study the qualitative problem for
    reachability and parity objectives on RMDPs without making any assumption over
    the structures of the RMDPs, e.g., unichain or aperiodic. Our contributions are
    twofold. We first present efficient algorithms with oracle access to uncertainty
    sets that solve qualitative problems of reachability and parity objectives. We
    then report experimental results demonstrating the effectiveness of our oracle-based
    approach on classical RMDP examples from the literature scaling up to thousands
    of states.

  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: "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: 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: "Solitons - localized wave packets that travel without spreading - play a
    central role in understanding transport and properties of nonlinear systems. In
    quantum many-body systems, however, such robust excitations are typically destroyed
    by thermalization. Here, we theoretically demonstrate the existence of solitonic
    excitations in high-energy states of Rydberg atom chains in the regime of strong
    nearest-neighbor Rydberg blockade. \r\nThese localized wave packets propagate
    directionally atop a special class of reviving initial states related to quantum
    many-body scars and are capable of carrying energy. Exhibiting long coherence
    times, these states constitute a form of non-ergodic quantum dynamics and can
    be efficiently implemented on Rydberg atom simulators. In this work, in addition
    to a phenomenological description of solitons, we identify their counterpart in
    a classical nonlinear dynamical system, demonstrate their potential use in quantum
    information transfer, and conjecture their relevance for anomalous energy transport
    reported in numerical studies of Rydberg atom arrays."

  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.
