description: Structural behavior and equation of state of atomic and molecular crystal phases of dense hydrogen at pressures up to 3.5 TPa are systematically investigated with density functional theory. The results indicate that the Vinet EOS model that fitted to low-pressure experimental data overestimates the compressibility of dense hydrogen drastically when beyond 500 GPa. Metastable multi-atomic molecular phases with weak covalent bonds are observed. When compressed beyond about 2.8 TPa, these exotic low-coordinated phases become competitive with the groundstate and other high-symmetry atomic phases. Using nudged elastic band method, the transition path and the associated energy barrier between these high-pressure phases are evaluated. In particular for the case of dissociation of diatomic molecular phase into the atomic metallic Cs-IV phase, the existent barrier might raise the transition pressure about 200 GPa at low temperatures. Plenty of flat and broad basins on the energy surface of dense hydrogen have been discovered, which should take a major responsibility for the highly anharmonic zero point vibrations of the lattice, as well as the quantum structure fluctuations in some extreme cases. At zero pressure, our analysis demonstrates that all of these atomic phases of dense hydrogen known so far are unquenchable. NOTE: In the previous version of this paper (1010.3392v1) we made a mistake when evaluating the enthalpy of Cs-IV phase, which misled us to a conclusion that taking the multi-atomic molecular phases as the ground-state. After corrected this error, however, the atomic phase of Cs-IV becomes the static structure with the lowest enthalpy. Current version not only includes a substantial improvement of the previous one, but also contains many NEW interesting topics that were not touched before.

description: Trying to address the security challenges of a cloud-centric software deployment paradigm, silicon and cloud vendors are introducing confidential computing - an umbrella term aimed at providing hardware and software mechanisms for protecting cloud workloads from the cloud provider and its software stack. Today, Intel SGX, AMD SEV, Intel TDX, etc., provide a way to shield cloud applications from the cloud provider through encryption of the application's memory below the hardware boundary of the CPU, hence requiring trust only in the CPU vendor. Unfortunately, existing hardware mechanisms do not automatically enable the guarantee that a protected system was not tampered with during configuration and boot time. Such a guarantee relies on a hardware RoT, i.e., an integrity-protected location that can store measurements in a trustworthy manner, extend them, and authenticate the measurement logs to the user.
 In this work, we design and implement a virtual TPM that virtualizes the hardware RoT without requiring trust in the cloud provider. To ensure the security of a vTPM in a provider-controlled environment, we leverage unique isolation properties of the SEV-SNP hardware that allows us to execute secure services as part of the enclave environment protected from the cloud provider. We further develop a novel approach to vTPM state management where the vTPM state is not preserved across reboots. Specifically, we develop a stateless ephemeral vTPM that supports remote attestation without any persistent state on the host. This allows us to pair each confidential VM with a private instance of a vTPM completely isolated from the provider-controlled environment and other VMs. We built our prototype entirely on open-source components. Though our work is AMD-specific, a similar approach could be used to build remote attestation protocols on other trusted execution environments.

Intrinsic stationarity for vector quantization: Foundation of dual quantization
Creators: name: Pagès, Gilles

Publisher: name: arXiv
Year: 2010
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: We develop a new approach to vector quantization, which guarantees an intrinsic stationarity property that also holds, in contrast to regular quantization, for non-optimal quantization grids. This goal is achieved by replacing the usual nearest neighbor projection operator for Voronoi quantization by a random splitting operator, which maps the random source to the vertices of a triangle of $d$-simplex. In the quadratic Euclidean case, it is shown that these triangles or $d$-simplices make up a Delaunay triangulation of the underlying grid. Furthermore, we prove the existence of an optimal grid for this Delaunay -- or dual -- quantization procedure. We also provide a stochastic optimization method to compute such optimal grids, here for higher dimensional uniform and normal distributions. A crucial feature of this new approach is the fact that it automatically leads to a second order quadrature formula for computing expectations, regardless of the optimality of the underlying grid.

description: The stable critical points and their corresponding cosmology are derived in the teleparallel gravity with an added Gauss-Bonnet topological invariant term. We have analyzed the dynamics of the Universe by presenting two cosmological viable models, showing the potential to describe different phases of the evolution of the Universe. The value of the deceleration parameter ($q$), total equation of state parameter ($ω_{tot}$) and dark energy equation of state parameter ($ω_{DE}$) have been presented against each critical point. The existence and stability conditions are also presented. We study the behavior of the phase space trajectories at each critical point. Finally, the evolutionary behavior of the deceleration parameter and the equation of state parameters have been assessed with the initial condition of the dynamical variables, and compatibility has been observed in connection with the present cosmological scenario.

"A black writing upon the sky" : the interplay of knowledge, discourse, and power in Susanna Clarke's Jonathan Strange & Mr. Norrell
Creators: name: Fraser, Samuel Thomas
Publisher: name: University of British Columbia
Year: 2023

description: Susanna Clarke’s fantasy novel Jonathan Strange & Mr. Norrell depicts a feud between two magicians with opposing philosophies regarding the study and practice of magic in an alternate version of nineteenth-century England. Where Gilbert Norrell favours a ritualistic doctrine of textual analysis and logocentrism, Jonathan Strange takes a more experimental approach, adapting and extrapolating on old magical principles from both textual sources and oral folklore in order to suit new circumstances. Norrell’s highly structured process assumes a textual point of origin for every conceivable magical effect: every signifier has a single, clearly identifiable and unalterable signified, and thus reinterpretation is not possible. By contrast, Strange’s approach embraces ambiguous signifiers and contradictory signifieds, and acknowledges that a given word may have multiple meanings at the same time. For Strange, ambiguity and contradiction represent opportunities for reinvention and experimentation. Strange and Norrell’s disagreement over which methodology is superior reflects a larger tension between, on the one hand, formulaic modes of expression that are well-suited to standardized hierarchies of knowledge, authority, and power in a conservative status quo, and on the other hand, more elastic modes of expression better suited to subversive actors who achieve success outside of or despite the normative institutional frameworks of nineteenth-century English society. Through its depiction of the interaction between Regency England’s conservative halls of power and an increasingly subversive corpus of magical lore, the novel repeatedly exposes the limits and hypocrisies inherent in the static, restrained epistemology that Norrell champions. Because a form of this same epistemology also manifests in the ideological construction of social hierarchies, the novel simultaneously exposes the weaknesses of so-called “traditional” hierarchies and power structures. Instead, in multiple key moments, the novel focuses on individuals who do not conform to societal conventions, and highlights the successes they achieve by doing that which is unexpected. In this way, JSMN suggests that a more elastic form of discourse, which embraces ambiguity, contradiction, and experimentation, affords its users greater opportunities for success and has the potential to lead us to a more equitable future by challenging traditional modes of knowledge exchange.

A Python approach for GRB afterglow analysis: sAGa (Software for AfterGlow Analysis)
Creators: name: MARONGIU, MARCO
name: GUIDORZI, CRISTIANO
Publisher: name: O.A. Cagliari
Year: 2021

description: This technical note describes a fully self-consistent code in Python – called sAGa (Software for AfterGlow Analysis) – to cope with the complex landscape of GRB afterglows. sAGa adds up to other pre-existing broadband fitting tools in the literature and provides an independent check, emphasising the broadband study of GRB afterglows over the last two decades. This code aims to model GRB afterglow data within a self-consistent physically grounded picture. Built adopting a Bayesian approach, all the data set, from radio to gamma-rays, is modelled. By-products are plots of spectra and light-curves, and computation of the break frequencies and normalisations as a function of the shock microphysical parameters, such as the power-law index of the electron energy distribution, the fractions of the blastwave energy delivered to relativistic electrons and magnetic fields, and other parameters such as the kinetic energy of the explosion and the density of the circumburst medium (CBM). Dust extinction of optical along the sightline and scintillation in radio frequencies are also accounted for. sAGa has been successfully tested on the broadband data of the afterglows of GRB120521C, GRB090423, and GRB050904. Our results are consistent with those reported in the literature within 2 sigma. Moreover, the values of the power-law index of the electron energy distribution obtained from sAGa analysis are compatible with the inferences based on the lines of reasoning based on the observation of the optical/X-ray spectra.

description: We study the behaviour of geodesics on a Riemannian manifold near a generalized conical or cuspidal singularity. We show that geodesics entering a small neighbourhood of the singularity either hit the singularity or approach it to a smallest distance $δ$ and then move away from it, winding around the singularity a number of times. We study the limiting behaviour $δ\to0$ in the second case. In the cuspidal case the number of windings goes to infinity as $δ\to0$, and we compute the precise asymptotic behaviour of this number. The asymptotics have explicitly given leading term determined by the warping factor that describes the type of cuspidal singularity. We also discuss in some detail the relation between differential and metric notions of conical and cuspidal singularities.

description: This presentation was given at the Open Science Barcamp 2019 in Berlin.

Participatory research, that is when people who are not employed as scientists do research – on their own, in groups and potentially in cooperation with people who are employed as scientists. There are many different methodologies and approaches to participatory research, for instance DIY science, Community-based Research, Participatory Action Research and Citizen Science.

Such concepts are not often considered in discussions on Open Science, which are usually focussing on developments within scientific institutions. In my talk I will argue that it is important to extend the idea of Open Science beyond academia by considering another shade of openness – openness for participation of volunteers and cooperations with civil society organisations.

With a focus on Citizen Science, I will introduce a pluralistic concept of participatory research, highlight current developments and discuss challenges of this growing field of practice in Europe.

description: CAT(0) metric spaces constitute a far-reaching common generalization of Euclidean and hyperbolic spaces and simple polygons: any two points x and y of a CAT(0) metric space are connected by a unique shortest path γ(x,y). In this paper, we present an efficient algorithm for answering two-point distance queries in CAT(0) rectangular complexes and two of theirs subclasses, ramified rectilinear polygons (CAT(0) rectangular complexes in which the links of all vertices are bipartite graphs) and squaregraphs (CAT(0) rectangular complexes arising from plane quadrangulations in which all inner vertices have degrees \geq4). Namely, we show that for a CAT(0) rectangular complex K with n vertices, one can construct a data structure D of size $O(n^2)$ so that, given any two points x,y in K, the shortest path γ(x,y) between x and y can be computed in O(d(p,q)) time, where p and q are vertices of two faces of K containing the points x and y, respectively, such that γ(x,y) is contained in K(I(p,q)) and d(p,q) is the distance between p and q in the underlying graph of K. If K is a ramified rectilinear polygon, then one can construct a data structure D of optimal size O(n) and answer two-point shortest path queries in O(d(p,q)logΔ) time, where Δ is the maximal degree of a vertex of G(K). Finally, if K is a squaregraph, then one can construct a data structure D of size O(nlogn) and answer two-point shortest path queries in O(d(p,q)) time.

description: We consider axial (or odd-parity) perturbations of non-spinning hairy black holes (BH) in shift-symmetric DHOST (Degenerate Higher-Order Scalar-Tensor) theories, including terms quartic and cubic in second derivatives of the scalar field. We give a new formulation of the effective metric in which axial perturbations propagate as in general relativity. We then introduce a generic parametrization of the effective metric in the vicinity of the background BH horizon. Writing the dynamics of the perturbations in terms of a Schrödinger-like operator, we discuss in which cases the operator is (essentially) self-adjoint, thus leading to an unambiguous time evolution, according to the choice of parameters characterizing the near-horizon effective metric. This is in particular useful to investigate the stability of the perturbations. We finally illustrate our general analysis with two examples of BH solutions.

Compact electro/optical packaging enabled by photonics wire bonding
Creators: name: Yu, Shangxuan
Publisher: name: University of British Columbia
Year: 2023

description: Three-dimensional freeform optical waveguides, or photonic wired bonding (PWB), is a versatile technology that enables low-loss interconnects between photonics components. With two-photon lithography, PWB can match the mode profile and position mismatch between single-mode fibers, photonics integrated chips (PIC), and semiconductor lasers, rendering the costly active alignment obsolete. Despite the advantages of the PWB technology, compact packaging solutions must be developed to fully cultivate its potential in interconnecting photonics components and work with existing integrated photonics functionalities. We review the basics of photonics packaging. The working principle and technical specifications of PWB are summarized. Laser integration and fiber attachment methods are reviewed. More technical details like the fabrication process and structure of PWB are introduced. Moreover, we proposed a series of simulations to optimize the PWB geometry for efficient coupling. The mode coupler shape and its vertical offset tolerance are simulated by mode overlapping, and the constant cross-section waveguide's single operation condition and bending loss are investigated. The mode size convertor between mode couplers and constant cross-section waveguide is optimized to balance the footprint and good transmission. An intensity-modulated microring modulator (IM-MRR) based optical computing unit is demonstrated with PCB-based co-packaging with PWB for optical interconnection. A chip post-processing recipe is developed and calibrated for metalization rework. This is the first demonstration of using PWB for packaging neuromorphic systems. The potential of PWB to enable high-density optical I/O for the neuromorphic system is discussed. We propose a hybrid on-chip laser integration technology enabled by PWB. The photonics integrated chip (PIC) post-process and packaging process is illustrated. The deep reactive ion etching (DRIE) process is calibrated for etching on-chip recess cavities. Pure indium and Au₈₀S₂₀ preforms are tested for laser die soldering on bare silicon and gold-coated surface. A PWB-compatible compact assembly solution for electrical/optical co-packaging is developed. The assembly solution is implemented for investigating short-range optical feedback effects on distributed feedback lasers. The methods feature the least change on existing nanofabrication techniques while maintaining flexibility for off-the-shelf laser dies integration. This approach has great potential to enable low-cost hybrid integration for low-to-medium volume applications.

description: Development of new polymeric binders can help enable the use of silicon-rich anodes in Li-ion batteries, by providing stronger adhesion to the active material particles. The compositional features that improve interfacial interactions and mechanical properties can often impart electronic conductivity and redox activity to these polymers, which are generally seen as beneficial to cell performance. Alternatively, it is also possible that the addition of charge-transferring centers to the electrode can accelerate cell degradation. Here, we use an aromatic polyimide (~320 mAh/g of reversible capacity) to explore how a redox-active conductive polymer can affect cell performance. We demonstrate that the lithiated polymer is less stable than the traditional binders upon storage, leading to increased rates of calendar aging. Furthermore, we show that the adhesion properties of the polymer deteriorate upon repeated cycling, to an extent that is proportional to the degree of delithiation of the binder. More critically, we show that progressive degradation of the redox behavior of the polymer leads to the release of extra Li+ into the cell, which can give the false perception of good performance even under conditions of poor stability. Our work suggests that redox-active conductive binders can sometimes be detrimental to cell performance, and that works evaluating new polymers must include careful experimental validation under realistic conditions.

description: The microstructure of black holes is a mystery. There is yet no resolution of basic questions such as what the constituent particles are. We work here with black hole thermodynamics (BHT), and the metric geometry of thermodynamics, which connects to interparticle interactions via the invariant thermodynamic Ricci scalar curvature $R$. $R$ may be calculated with BHT. In ordinary thermodynamics (OT), $R$ is positive/negative for interparticle interactions repulsive/attractive. Its magnitude is the correlation length. The basic universality of thermodynamics leads us to expect similar relations for BHT. Our contribution here is motivated by a physical simplification that frequently occurs at low temperatures $T$ in OT: complicated interactions tend to freeze out, leaving only basic quantum statistical interactions, those of ideal Fermi or Bose gasses. Our hope is that similar simplification happens in black holes in the extremal limit, where the BHT temperature $T \to 0$. We evaluate the extremal $R$ for twelve BHT literature models, working with the independent variables mass, angular momentum, charge, and the cosmological constant, $\{M,J,Q,Λ\}$, respectively. We allowed only two of these variables to fluctuate at a time, with the other two fixed. $M$ always fluctuated, either $J$ or $Q$ fluctuated, and $Λ$ was always fixed. At constant average $M$, $R$ has limiting divergence $R=c\,T^{-1}$, with the nonsingular constant $c$ depending only on $M$ and the two fixed parameters. $c$ is positive for $11/12$ of the models we examined, and negative only for the tidal charged model. The positive sign for $R$ indicates a BHT microstructure composed of particles with repulsive (fermionic) interactions. The limiting BHT expression for $R$ resembles that for 2D and 3D ideal Fermi gasses at constant volume, which also have limiting divergence $R=c\,T^{-1}$, with positive $c$.

description: In low-dimensional topology, many important decision algorithms are based on normal surface enumeration, which is a form of vertex enumeration over a high-dimensional and highly degenerate polytope. Because this enumeration is subject to extra combinatorial constraints, the only practical algorithms to date have been variants of the classical double description method. In this paper we present the first practical normal surface enumeration algorithm that breaks out of the double description paradigm. This new algorithm is based on a tree traversal with feasibility and domination tests, and it enjoys a number of advantages over the double description method: incremental output, significantly lower time and space complexity, and a natural suitability for parallelisation. Experimental comparisons of running times are included.

Radiative capture and decays in ab initio nuclear theory
Creators: name: Gysbers, Peter
Publisher: name: University of British Columbia
Year: 2023

description: Atomic nuclei exhibit many phenomena not limited to excited states, decays, reactions, and clustering. Nuclear processes control the evolution of stars and explain the abundances of chemical elements in the universe. Nuclear physics can be used to answer fundamental questions about underlying particle physics and cosmology, such as the symmetry between matter and antimatter or the nature of neutrinos. The discrepancy between theoretical predictions and observations motivates improved theory and can provide evidence for new physics. A predictive model of nuclei is needed as input for experimental tests and for astrophysical models. Nuclei are complex strongly-interacting quantum many-body systems. Accurate the- oretical techniques are required to predict the rate of nuclear decay processes, the cross section of nuclear reactions and the distribution of the emitted particles. Ab initio nuclear theory takes advantage of the recent rapid increase in computing power to calculate nuclear structure and reactions solely from realistic interactions between the constituent nucleons. In this thesis, we first present beta-decay calculations using the ab initio no-core shell model. Our calculations provide an explanation for the quenching of Gamow-Teller beta- decays, provide nuclear structure corrections to the beta-spectrum necessary to interpret experiments seeking to find new physics and provide estimates for the hypothetical process of neutrinoless double-beta decay. Second, we present radiative capture calculations using the no-core shell model with continuum, an extension which places bound and scattering states on equal footing. The rate of radiative capture reactions in big bang nucleosynthesis is required to estimate the abundance of isotopes in the early universe. In addition, anomalies in recent radiative capture experiments claim the discovery of a new boson. Comparing to these experiments requires prediction of the distribution of electron-positron pairs produced by radiative capture.

description: It was predicted and recently experimentally confirmed that systems with microscopically reversible dynamics in locally quadratic potentials warm up faster than they cool down. This thermal relaxation asymmetry challenged the local-equilibrium paradigm valid near equilibrium. Because the intuition and proof hinged on the dynamics obeying detailed balance, it was not clear whether the asymmetry persists in systems with irreversible dynamics. To fill this gap, we here prove the relaxation asymmetry for systems driven out of equilibrium by a general linear drift. The asymmetry persists due to a non-trivial isomorphism between driven and reversible processes. Moreover, rotational motions emerge that, strikingly, occur in opposite directions during heating and cooling. This highlights that noisy systems do not relax by passing through local equilibria.

description: We propose formulas for the Lüscher type finite size energy correction of multiparticle states on the interval and evaluate them for the simplest case in the AdS/CFT setting. By this we determine the leading wrapping correction to the anomalous dimension of the simplest determinant type operator, which corresponds to a one particle state on the Y=0 brane.

description: We theoretically and experimentally study the universal scaling property of the spin-1/2 Kondo state in the magnetic field dependence of bias-voltage linear conductance through a quantum dot at low temperatures. We discuss an efficient and reliable procedure to evaluate the Kondo temperature defined at the ground state from experimental or numerical data sets of the magnetic field dependence of the linear conductance or the magnetization of the quantum dot. This procedure is helpful for quantitative comparison of the theory and the experiment, and useful in Kondo-correlated systems where temperature control over a wide range is difficult, such as for cold atoms. We demonstrate its application to experimentally measured electric current through a carbon nanotube quantum dot.

description: In a quasi-particle model of QCD matter at finite temperature with thermal masses for quarks and gluons from hard thermal loops, the equation of state (EOS) can be described by an effective temperature dependence of the strong coupling $g(T)$. Assuming the same effective coupling between the exchanged gluon and thermal partons, the EOS can also be related to parton energy loss.} Based on the quasi-particle linear Boltzmann transport (QLBT) model coupled to a (3+1)-dimensional viscous hydrodynamic model of the quark-gluon plasma (QGP) evolution and a hybrid fragmentation-coalescence model for heavy quark hadronization, we perform a Bayesian analysis of the experimental data on $D$ meson suppression $R_{\rm AA}$ and anisotropy $v_2$ at RHIC and the LHC. We achieve a simultaneous constraint on the QGP EOS and the heavy quark transport coefficient, both consistent with the lattice QCD results.

description: The success of analytic waveform modeling within the effective-one-body (EOB) approach relies on the precise understanding of the physical importance of each technical element included in the model. The urgency of constructing progressively more sophisticated and complete waveform models (e.g. including spin precession and eccentricity) partly defocused the research from a careful comprehension of each building block (e.g. Hamiltonian, radiation reaction, ringdown attachment). Here we go back to the spirit of the first EOB works. We focus first on nonspinning, quasi-circular, black hole binaries and analyze systematically the mutual synergy between numerical relativity (NR) informed functions and the high post-Newtonian corrections (up to 5PN) to the EOB potentials. Our main finding is that it is essential to correctly control the noncircular part of the dynamics during the late plunge up to merger. We then improve the {\tt TEOBResumS-GIOTTO} waveform model for quasi-circular, spin-aligned black hole binaries. We obtain maximal EOB/NR unfaithfulness ${\bar{F}}^{\rm max}_{\rm EOBNR}\sim 10^{-3}$ (with Advanced LIGO noise and in the total mass range $10-200M_\odot$) for the dominant $\ell=m=2$ mode all over the 534 spin-aligned configurations available through the Simulating eXtreme Spacetime catalog. The model performance, also including higher modes, is then explored using the NR surrogates \nrsurqeight{} and \nrsurqfifteen, to validate it up to mass ratio $m_1/m_2=15$. We find that, over the set of configurations considered, more than $98\%$ of the total-mass-maximized unfaithfulness lie below the $3\%$ threshold when comparing to the surrogate models.

description: This work examines the deformed fuzzy sphere, as an example of a fuzzy space that can be described through a spectral triple, using computer visualisations. We first explore this geometry using an analytic expression for the eigenvalues to examine the spectral dimension and volume of the geometry.
 In the second part of the paper we extend the code from our past work with Abel Stern, in which the truncated sphere was visualized through localized states. This generalisation allows us to examine finite spectral triples. In particular, we apply this code to the deformed fuzzy sphere as a first step in the more ambitious program of using it to examine arbitrary finite spectral triples, like those generated from random fuzzy spaces.

description: The spin Hall effect (SHE) can generate a pure spin current by an electric current, which is promisingly used to electrically control magnetization. To reduce power consumption of this control, a giant spin Hall angle (SHA) in the SHE is desired in low-resistivity systems for practical applications. Here, critical spin fluctuation near the antiferromagnetic (AFM) phase-transition is proved as an effective mechanism to create an additional part of SHE, named as fluctuation spin Hall effect (FSHE). This FSHE enhances the SHA due to the AFM spin fluctuation between conduction electrons and local spins. We detect the FSHE with the inverse and direct spin Hall effect (ISHE and DSHE) set-up and their temperature (T) dependences in the Cr/MgO/Fe magnetic tunnel junctions (MTJs). The SHA is significantly enhanced when temperature is approached to the Néel temperature (T_N) and has a peak value of -0.34 at 200 K near T_N. This value is higher than the room-temperature value by 240% and comparable to that of heavy metals Ta and W. Furthermore, the spin Hall resistivity of Cr well fits the modeled T-dependence when T approaches T_N from low temperatures, implying the AFM spin fluctuation nature of strong SHA enhancement. Thus, this study demonstrates the critical spin fluctuation as a prospective way of increasing SHA and enriches the AFM material candidates for spin-orbitronic devices.

description: OBJECTIVES: Although morphological attributes of cells and their substructures are recognized readouts of physiological or pathophysiological states, these have been relatively understudied in amyotrophic lateral sclerosis (ALS) research. MATERIALS AND METHODS: In this study, we integrate multichannel fluorescence high-content microscopy data with deep-learning imaging methods to reveal - directly from unsegmented images - novel neurite-associated morphological perturbations associated with (ALS-causing) VCP-mutant human motor neurons (MNs). RESULTS: Surprisingly, we reveal that previously unrecognized disease-relevant information is withheld in broadly used and often considered 'generic' biological markers of nuclei (DAPI) and neurons (β III-tubulin). Additionally, we identify changes within the information content of ALS-related RNA binding protein (RBP) immunofluorescence imaging that is captured in VCP-mutant MN cultures. Furthermore, by analysing MN cultures exposed to different extrinsic stressors, we show that heat stress recapitulates key aspects of ALS. CONCLUSIONS: Our study therefore reveals disease-relevant information contained in a range of both generic and more specific fluorescent markers, and establishes the use of image-based deep learning methods for rapid, automated and unbiased identification of biological hypotheses.
