  text: The development of complex tissues relies on the precise assignment of cell
    identity. At the molecular scale, this process depends on the deposition of epigenetic
    modifications—such as methylation—that are regulated by complex biochemical networks
    and occur at specific regions on the DNA and chromatin. Here we show that despite
    the complexity of epigenetic regulation, dynamical scaling and self-similarity
    of DNA methylation marks emerge in embryonic development. Drawing on single-cell
    multi-omics experiments, super-resolution microscopy and statistical physics,
    we demonstrate that these phenomena originate in dynamical feedback between DNA
    methylation and the formation of nanoscale dynamic chromatin aggregates. These
    nanoscale processes lead to genome-wide increase in DNA methylation marks following
    a power law and self-similar correlation functions. Using this framework, we identify
    methylation patterns that precede gene expression changes in embryonic symmetry
    breaking. Our work identifies linear sequencing measurements as a laboratory to
    study mesoscopic biophysical processes in vivo.

  text: "As neural-network-based models grow both in size and popularity, interest
    has grown in making the models smaller and more efficient to train. To that end,
    many methods have been proposed to prune models by reducing their number of nonzero
    parameters. Additionally, parameter-efficient fine-tuning, in which a much smaller
    number of parameters than the total contained in the model is updated during training,
    has become very popular, especially in the space of Large Language Models. At
    the same time, the increasingly routine deployment of machine learning in real-world
    applications has spurred a drive to make them more trustworthy - in the sense
    of, among other things, being unbiased, interpretable, and editable. In this thesis,
    we examine the interplay between efficiency and trustworthiness.\r\n\r\nFirst,
    we analyze the effects of model pruning on bias in computer vision models, demonstrating
    that increased sparsity leads to greater bias, largely as a function of increased
    model uncertainty in marginal cases. Based on this observation, we propose several
    bias mitigation techniques. Then, we demonstrate that example-specific model pruning
    can improve model interpretation methods while improving pruning efficiency to
    make example-specific model pruning feasible in real time. Then, we investigate
    the effectiveness of parameter-efficient and data-efficient model personalization
    via fine-tuning, demonstrating that it is highly feasible with very small computational
    and data resources. Finally, we consider efficiency in editing model knowledge
    using a custom synthetic data framework, demonstrating that parameter-efficient,
    low-rank fine-tuning frequently outperforms full-rank fine-tuning, and, additionally,
    that restricting which model blocks are fine-tuned frequently improves results.
    Together, the results in this thesis provide new insights and techniques for combining
    trustworthiness and efficiency during neural network inference and training.\r\n\r\n-----------------“In

  text: "The availability of powerful open-source large language models (LLMs) opens
    exciting use cases, such as using personal data to fine-tune these models to imitate
    a user’s unique writing style. Two key requirements for this functionality are
    personalization–in the sense that the output should recognizably reflect the user’s
    own writing style—and privacy–users may justifiably be wary of uploading extremely
    personal data, such as their email archive, to a third-party service. In this
    paper, we demonstrate the feasibility of training and running such an assistant,
    which we call Panza, on commodity hardware, for the specific use case of email
    generation. Panza’s personalization features are based on a combination of parameter-efficient
    fine-tuning using a variant of the Reverse Instructions technique [1] and Retrieval-Augmented
    Generation (RAG) [2]. We demonstrate that this combination allows us to fine-tune
    an LLM to reflect a user’s writing style using limited data, while executing on
    extremely limited resources, e.g. on a free Google Colab instance. Our key methodological
    contribution is the first detailed study of evaluation metrics for this task,
    and\r\nof how different choices of system components–the use of RAG and of different
    fine-tuning approaches–impact the system’s performance. Additionally, we demonstrate
    that very little data - under 100 email samples - are sufficient to create models
    that convincingly imitate humans, showcasing a previously unknown attack vector
    in language models. We are releasing the full Panza code as well as three new
    email datasets licensed for research use."

  text: As artificial neural networks, and specifically large language models, have
    improved rapidly in capabilities and quality, they have increasingly been deployed
    in real-world applications, from customer service to Google search, despite the
    fact that they frequently make factually incorrect or undesirable statements.
    This trend has inspired practical and academic interest in model editing, that
    is, in adjusting the weights of the model to modify its likely outputs for queries
    relating to a specific fact or set of facts. This may be done either to amend
    a fact or set of facts, for instance, to fix a frequent error in the training
    data, or to suppress a fact or set of facts entirely, for instance, in case of
    dangerous knowledge. Multiple methods have been proposed to do such edits. However,
    at the same time, it has been shown that such model editing can be brittle and
    incomplete. Moreover the effectiveness of any model editing method necessarily
    depends on the data on which the model is trained, and, therefore, a good understanding
    of the interaction of the training data distribution and the way it is stored
    in the network is necessary and helpful to reliably perform model editing. However,
    working with large language models trained on real-world data does not allow us
    to understand this relationship or fully measure the effects of model editing.
    We therefore propose Behemoth, a fully synthetic data generation framework. To
    demonstrate the practical insights from the framework, we explore model editing
    in the context of simple tabular data, demonstrating surprising findings that,
    in some cases, echo real-world results, for instance, that in some cases restricting
    the update rank results in a more effective update.

  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: Magneto-optic Kerr effect (MOKE) is a powerful probe of broken time-reversal
    symmetry (T), typically used to study ferromagnets. While MOKE has been observed
    in some antiferromagnets (AFMs) with vanishing magnetization, it is often associated
    with structures whose symmetry is lower than basic collinear, bipartite order.
    In contrast, theory predicts a mechanism for MOKE intrinsic to all AFMs of A-type,
    i.e. layered AFMs in which ferromagnetic layers are antiferromagnetically aligned.
    Here we report the experimental confirmation of this mechanism in a bulk AFM.
    We achieve this by measuring the imaginary component of MOKE as a function of
    photon energy in MnBi2Te4, an A-type AFM where T is preserved in combination with
    a translation, and comparing the experimental results with model calculations.
    Our model suggests that observable MOKE should be expected in all collinear A-type
    AFMs with out-of-plane spin order, thus enabling optical detection of AFM domains
    and expanding the scope of MOKE to few-layer AFMs.

  text: "I review recent contributions on nonlinear Dirichlet forms. Then, I specialise
    to the case of 2-\r\nhomogeneous and local forms. Inspired by the theory of Finsler
    manifolds and metric measure spaces, I establish new properties of such nonlinear
    Dirichlet forms, which are reminiscent of differential calculus formulae."

  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.

  text: Three-dimensional (3D) printing has rapidly developed from a niche hobbyist
    activity into a widely accessible and indispensable technology across multiple
    scientific disciplines. Within microscopy, optical engineering laboratories and
    imaging core facilities, 3D printing enables creating customised solutions for
    sample holders, optical components and everyday laboratory tools that traditionally
    required specialised machining. By providing rapid prototyping, low-cost production
    and reproducibility, 3D printing facilitates innovation and efficiency in facility
    operations. This article provides a perspective on the possibilities, challenges,
    and practical aspects of implementing 3D printing within microscopy core facilities.
    Instead of providing technical review about 3D printing, we focus on service organisation,
    user engagement, resource management and community-driven repositories for design
    dissemination. Our aim is to share insights with those considering the implementation
    of 3D printing as a service for developing add-on components to ease the operation
    of different aspects of the machine-park driven services and those who are managing
    advanced instrumentation within research groups.

  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: Redox-mediated flow batteries boost energy density by utilizing dissolved
    redox species as charge carriers for solid charge-storage materials. This strategy
    strongly depends on the thermodynamics and kinetics between the solid booster
    and dissolved redox species. Conventional electrochemical methods often convolute
    intrinsic reactivity with mass transport effects, introducing complexity in determining
    limiting steps. We propose a strategy that confines solid boosters within recessed
    microelectrodes and employs scanning electrochemical microscopy (SECM) to estimate
    reaction kinetics between booster and dissolved active redox species. Confining
    the solid booster in the recessed microelectrode overcomes mass transport limitations
    of dissolved redox species and enables controlled polarization of the booster
    material, allowing deconvolution of key rate-determining factors. As an initial
    model system, Prussian blue-ferricyanide/ferrocyanide [Fe(CN)6]3−/4− was used
    as solid booster and dissolved redox active species, respectively. The methodology
    was further explored for copper hexacyanoferrate with N,N,N-2,2,6,6-heptamethylpiperidinyl
    oxy-4-ammonium chloride and nickel hydroxide with [Fe(CN)6]3−/4− and extended
    to Mn-based Prussian blue analogues in combination with organic redox species.
    Our results demonstrate that SECM coupled with the proposed recessed microelectrode
    strategy provides a powerful platform to disentangle interfacial kinetics and
    guide the rational design of solid booster-dissolved redox species and electrolytes
    for high-performance redox-mediated flow batteries.

  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.
