However, the long cultivation cycle and susceptibility to diseases hinder the advancement of the ginseng industry. Here, we demonstrate that the embryonic protoderm of ginseng can efficiently produce ginsenosides. Single-cell transcriptome and mass spectrometry imaging analyses reveal that ginsenosides accumulate in the protoderm of ginseng embryonic callus (EC) at levels comparable to those in forest ginseng. Epigenetic analyses indicate that elevated histone acetylation and enhanced chromatin accessibility at regeneration- and ginsenoside metabolism-related gene loci are associated with the ginsenoside-producing capacity of EC. Increasing histone acetylation levels or overexpressing the regeneration-related WUSCHEL-RELATED HOMEOBOX11 (WOX11) gene further enhances ginsenoside production in EC. Our findings suggest that the protoderm of EC could serve as an in situ biological compartment for high-efficiency ginsenoside producion, offering a complementary approach to traditional ginseng cultivation. acknowledgement: 'The authors are grateful to Professor Linfeng Li from the School of Life Science, Fudan University, for his assistance during the ginseng genome annotation.

However, in single-molecule circuits this magnetic field is usually weak. Here we show that radially π-conjugated carbon structures can support amplified circulating currents that generate local magnetic fields. Within tight-binding and density functional theory (DFT) frameworks, we first study cycloparaphenylene (CPP) junctions where both electrodes are attached to the same phenylene unit on the nanohoop. We observe an energy-dependent ring current component that traverses the whole macrocycle by mapping the local current density. Importantly, we find that destructive interference near degenerate resonances can reverse the ring current direction and amplify it strongly relative to the source–drain current. We show that this interference-driven design principle is general, and also carries over to C60 junctions. In fullerene, lower-lying degenerate resonances are more easily accessible through electrostatic gating, reaching a magnetic field of 14.2 mT under a 100 mV source–drain bias. This work thus provides new insights into ring currents in radially π-conjugated carbon structures and highlights their potential as design platforms for single-molecule electromagnets. acknowledgement: The authors thank Jascha Repp from the University of Regensburg for helpful discussions.

NMR spectroscopy provides this insight at atomic resolution, yet for large proteins the difficulty of resonance assignment has largely confined such studies to systems below ∼50 kDa, or to observing only methyl groups. Here we present an integrated magic-angle spinning (MAS) and solution NMR study of the 134 kDa tetrameric malate dehydrogenase from Ignicoccus islandicus (IiMDH), an enzyme of particular interest as an evolutionary intermediate between allosteric lactate\r\ndehydrogenases and non-allosteric malate dehydrogenases. By combining high-dimensional (up to 4D) MAS NMR experiments on sedimented protein with solution NMR, we achieved 92% backbone heavy- atom assignment and 91% assignment of all Ile-δ1, Leu-δ1/-δ2, Val-γ1/-γ2, Met-ε and Thr-γ methyl groups. Building on these assignments, we use various probes of backbone and sidechain dynamics: elevated MAS NMR 15N rotating-frame relaxation (R1ρ) points to microsecond motions in functionally critical regions, including the catalytic loop and the mobile surface loop. Complementary methyl-axis order parameters from solution NMR identified additional flexible sites in the hydrophobic core. Chemical shift perturbation experiments upon addition of the substrate analogue oxamate, monitored via backbone 1H-15N TROSY, revealed both active-site contacts and responses in helices α2F and α3G, regions implicated in allosteric signal transmission. The integrated approach demonstrated here exploits the distinct strengths of MAS and solution NMR, and provides a comprehensive view of structure, dynamics, and substrate interactions in a large oligomeric enzyme that would not be accessible by either technique alone." acknowledged_ssus: - _id: NMR - _id: LifeSc acknowledgement: This research was supported by the Scientific Service Units (SSU) of Institute of Science and Technology Austria (ISTA) through resources provided by the Nuclear Magnetic Resonance and the Lab Support Facilities.

How spinal circuits and their cell types evolved to support this transition remains unclear. We leverage frog metamorphosis, which recapitulates this transition within a single organism, to define how spinal circuits generate aquatic versus terrestrial motor patterns. At swim stages, spinal architecture is uniform, with a transcriptionally and anatomically homogeneous motor and interneurons. As limbs develop and their movement complexifies, spinal circuits expand in neuron number and subtype diversity. This expansion is most pronounced for V1 inhibitory neurons, which increase ∼70-fold and diversify into transcriptionally distinct subtypes. Disrupting transcription factors defining emerging motor and V1 populations reveals molecular segregation between swim and limb circuits, highlighting the role of subtype diversity in motor coordination. A multifold increase in inhibitory neuron diversity thus underlies the tail-to-limb locomotor transition, providing a framework for spinal circuit adaptation during vertebrate evolution. acknowledged_ssus: - _id: Bio - _id: LifeSc acknowledgement: 'We would like to thank the members of the Sweeney Lab, Mario de Bono, Michael Forsthofer, Katharina Lust, and Meital Oren, for comments on the manuscript.

Furthermore, we also consider the case of MLS and provide the first lower bound showing that its communication complexity is much worse than previously believed, i.e., it is very far from $ \\log(N) $.\r\nFinally, we also propose a variant of MLS which provably achieves the same security properties with a much lower communication cost." alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Miguel full_name: Cueto Noval, Miguel id: ffc563a3-f6e0-11ea-865d-e3cce03d17cc last_name: Cueto Noval orcid: 0000-0002-2505-4246 citation: ama: Cueto Noval M.

The objects of interest can be often realized as cohomological invariants of algebraic\r\nvarieties, and good understanding of their geometry sheds light into the original questions.\r\nSuch techniques have seen immense applications in the Langlands program, where they go\r\nunder the label of geometric representation theory.\r\n\r\nOne source of powerful invariants in algebraic geometry comes from algebraic K-theory,\r\nHochschild homology, and their relatives. These localizing invariants contain large amount\r\nof information, but are quite hard to compute. For this reason, their usage in geometric\r\nrepresentation theory has been limited.\r\n\r\nThe aim of this thesis is to showcase how to control such invariants in the situations of\r\ninterest and use them to obtain new insights. We start by reinterpreting equivariant Hochschild\r\nhomology in terms of functions on certain fixed-point schemes, which are of independent\r\ninterest. We compare it to equivariant K-theory via the trace map. We give new computations\r\nand comparisons of such invariants of affine Schubert varieties in Gr, including arithmetic\r\nsituations. We show that they behave much better than expected.\r\n\r\nWe finally utilize this circle of ideas in a purely topological setting. We describe the varying\r\nfixed points of the extended torus action on the affine Grassmannian, and use it to compute\r\nits equivariant topological K-theory ring. The answer is nontrivial and verifies an outstanding\r\nconjecture in the subject.\r\n\r\nWe compare, partly conjecturally, the resulting K-theory ring to the completed center of an\r\nintegral even hybrid quantum group and its deformed quantum category O.

We establish various structural results for equivariant perfect algebraic K-theory on the way; we believe these are of independent interest. acknowledgement: "I would like to thank the following people for fruitful discussions,\r\nhelpful sanity checks or comments on previous drafts: Roman Bezrukavnikov, Jens Niklas Eberhardt, Mischa Elkner, Tamás Hausel, Andres Fernandez Herrero, Adeel Khan,\r\nBernhard Köck, Andrei Konovalov, Quoc Ho, Mirko Mauri, Matthew Morrow, Charanya\r\nRavi, Kamil Rychlewicz, Shyiu Shen, Vladimir Sosnilo, Georg Tamme, Xinwen Zhu.

Despite its ubiquity, the microscopic origin of CE remains unclear. In this thesis, we investigate CE from three complementary perspectives: developing a quantitative method to measure charge at the nanoscale, exploring the dynamic behavior of charge on insulating surfaces, and uncovering the role of mechanical history in forming a triboelectric series.\r\n\r\nIn the first part, we establish a rigorous framework for converting qualitative Kelvin probe force microscopy (KPFM) voltage maps into quantitative charge density distributions. Using finite element method (FEM) simulations, we determine the point-spread function of the KPFM tip–sample geometry and demonstrate that the true surface charge can be reconstructed by numerical deconvolution. This procedure enables the recovery of both the magnitude and sign of charge density with high fidelity, resolving nanoscale features that are otherwise obscured. Applying the method to contact-charged SiO$_2$ surfaces, we show that existing analytical approximations, such as parallel plate or spherical models, can miscalculate charge magnitude by orders of magnitude. Our hybrid FEM/KPFM approach therefore provides a fast and general method to convert qualitative KPFM signals into quantitative charge data, enabling nanoscale charge mapping under realistic experimental conditions.\r\n\r\nIn the second part, we study the temporal stability of CE-induced charges and identify the key material factors that determine whether KPFM can capture meaningful charge patterns. Through time-resolved experiments combining a custom-built transfer system with both microscopic and macroscopic measurements, we demonstrate that only the best insulators, such as SiO$_2$, preserve CE charge long enough for stationary imaging. For less conductive polymers, such as PDMS, charge decays within the duration of a single KPFM scan due to bulk conduction. Using a simple capacitor-based model, we reproduce the observed decay dynamics and confirm that the transferred charge decays characteristic to the sample's bulk conductivity. Further, we always observe homogeneous charge transfer.\r\n\r\nIn the third part, we address the question: can we form a triboelectric series with identical materials? Using controlled repetitive contact experiments, we show that nominally identical materials can progressively order themselves into a triboelectric series, where surfaces with more contact history charge negatively relative to fresher ones. By constructing a minimal model based on this ``contact bias'', we replicate the evolution from random to ordered charging observed in experiments. Supporting surface analyses, including atomic force microscopy, reveal that repeated contact induces nanoscale morphological changes, suggesting a mechanism tightly coupled to mechanical strain. These results highlight the crucial role of surface history and nanoscale mechanics in dictating charge transfer, motivating further exploration of mechanisms such as mechanochemical bond cleavage and flexoelectric polarization." acknowledged_ssus: - _id: NanoFab - _id: ScienComp - _id: LifeSc - _id: M-Shop - _id: EM-Fac acknowledgement: "This project has received financing from the European Research Council grant agreement\r\nno. 949120 under the European Union’s Horizon 2020 research and innovation programme.\r\nThis research was supported by the Scientific Service Units of The Institute of Science\r\nand Technology Austria (ISTA) through resources provided by the Miba Machine Shop, the\r\nNanofabrication Facility, the Lab Support Facility, the Scientific Computing Facility and the\r\nElectron Microscopy Facility.

The plasmid-encoded ParMRC system forms actin-like filaments that segregate low–copy number plasmids. In multicellular cyanobacteria such as Anabaena sp., we found that a chromosomally encoded ParMR system has evolved into a cytoskeletal system named CorMR with a function in cell shape control rather than DNA segregation. Live-cell imaging, in vitro reconstitution, and cryo–electron microscopy revealed that CorM formed dynamically unstable, antiparallel double-stranded filaments that were recruited to the membrane by CorR through an amphipathic helix conserved in multicellular cyanobacteria. CorMR filaments were regulated by MinC, which excluded them from the poles and division plane. Comparative genomics indicated that the repurposing of ParMR and Min systems coevolved with cyanobacterial multicellularity, highlighting the evolutionary plasticity of cytoskeletal systems in bacteria. acknowledged_ssus: - _id: Bio - _id: ScienComp - _id: EM-Fac - _id: LifeSc acknowledgement: "We thank all members of the Loose lab at ISTA for helpful discussions; M.

[Foteini Baldimtsi et al., 2022]. The general idea is to try out many inputs to some cryptographic algorithm until the output (e.g. a public-key or some hash value) falls into some sparse set and thus can be compressed: by trying out an expected 2^k different inputs one will find an output that starts with k zeros.\r\nUsing such truncation one can for example save substantial gas fees on Blockchains where storing values is very expensive. While [Foteini Baldimtsi et al., 2022] show that truncation preserves the security of the underlying primitive, they only consider a setting without preprocessing. In this work we show that lower bounds on the time-space tradeoff for inverting random functions and permutations also hold with truncation, except for parameters ranges where the bound fails to hold for \"trivial\" reasons.\r\nConcretely, it’s known that any algorithm that inverts a random function or permutation with range N making T queries and using S bits of auxiliary input must satisfy S⋅ T ≥ Nlog N. This lower bound no longer holds in the truncated setting where one must only invert a challenge from a range of size N/2^k, as now one can simply save the replies to all N/2^k challenges, which requires S = log N⋅ N /2^k bits and allows to invert with T = 1 query.\r\nWe show that with truncation, whenever S is somewhat smaller than the log N⋅ N /2^k bits required to store the entire truncated function table, the known S⋅ T ≥ Nlog N lower bound applies." alternative_title: - LIPIcs article_number: 4:1-4:10 article_processing_charge: Yes author: - first_name: Krzysztof Z full_name: Pietrzak, Krzysztof Z id: 3E04A7AA-F248-11E8-B48F-1D18A9856A87 last_name: Pietrzak orcid: 0000-0002-9139-1654 - first_name: Pengxiang full_name: Wang, Pengxiang last_name: Wang citation: ama: 'Pietrzak KZ, Wang P.

For example, besides the prediction quality, this could be the efficiency, robustness or fairness of the learned models, or any of their combinations. Multi-objective learning offers a natural framework for handling such problems without having to commit to early trade-offs. Surprisingly, statistical learning theory so far offers almost no insight into the generalization properties of multi-objective learning. In this work, we make first steps to fill this gap: We establish foundational generalization bounds for the multi-objective setting as well as generalization and excess bounds for learning with scalarizations. We also provide the first theoretical analysis of the relation between the Pareto-optimal sets of the true objectives and the Pareto-optimal sets of their empirical approximations from training data. In particular, we show a surprising asymmetry: All Pareto-optimal solutions can be approximated by empirically Pareto-optimal ones, but not vice versa.' acknowledgement: Open access funding provided by Institute of Science and Technology (IST Austria). article_processing_charge: Yes (via OA deal) article_type: original arxiv: 1 author: - first_name: Peter full_name: Súkeník, Peter id: d64d6a8d-eb8e-11eb-b029-96fd216dec3c last_name: Súkeník - first_name: Christoph full_name: Lampert, Christoph id: 40C20FD2-F248-11E8-B48F-1D18A9856A87 last_name: Lampert orcid: 0000-0001-8622-7887 citation: ama: Súkeník P, Lampert C.

A new frontier in this area is given by dynamic, non-uniform compression methods, which adjust the compression levels (e.g., sparsity) per-block or even per-layer in order to minimize accuracy loss, while guaranteeing a global compression threshold. Yet, current methods rely on estimating the "importance" of a given layer, implicitly assuming that layers contribute independently to the overall compression error. We begin from the motivating observation that this independence assumption does not generally hold for LLM compression: pruning a model further may even significantly recover performance. To address this, we propose EvoPress, a novel evolutionary framework for dynamic LLM compression. By formulating dynamic compression as a general optimization problem, EvoPress identifies optimal compression profiles in a highly efficient manner, and generalizes across diverse models and compression techniques. Via EvoPress, we achieve state-of-the-art performance for dynamic compression of Llama, Mistral, and Phi models, setting new benchmarks for structural pruning (block/layer dropping), unstructured sparsity, and quantization with dynamic bitwidths.' alternative_title: - PMLR article_processing_charge: No arxiv: 1 author: - first_name: Oliver full_name: Sieberling, Oliver last_name: Sieberling - first_name: Denis full_name: Kuznedelev, Denis last_name: Kuznedelev - first_name: Eldar full_name: Kurtic, Eldar id: 47beb3a5-07b5-11eb-9b87-b108ec578218 last_name: Kurtic - first_name: Dan-Adrian full_name: Alistarh, Dan-Adrian id: 4A899BFC-F248-11E8-B48F-1D18A9856A87 last_name: Alistarh orcid: 0000-0003-3650-940X citation: ama: 'Sieberling O, Kuznedelev D, Kurtic E, Alistarh D-A.

We develop a general layer-wise quantization framework with tight variance and code-length bounds, adapting to the heterogeneities over the course of training. We then apply a new layer-wise quantization technique within distributed variational inequalities (VIs), proposing a novel Quantized Optimistic Dual Averaging (QODA) algorithm with adaptive learning rates, which achieves competitive convergence rates for monotone VIs. We empirically show that QODA achieves up to a 150% speedup over the baselines in end-to-end training time for training Wasserstein GAN on 12+GPUs. acknowledgement: "This work was supported by Hasler Foundation Program: Hasler Responsible AI (project number 21043).
