In 1966, Hadwiger showed that any mass distribution in R^3 admits an eight-partition; moreover, one can prescribe the normal direction of one of the three planes. The analogous result for finite point sets follows by a standard limit argument. We prove the following variant of this result: any mass distribution (or point set) in R^3 admits an eight-partition for which the intersection of two of the planes is a line with a prescribed direction. Moreover, we present an efficient algorithm for calculating an eight-partition of a set of n points in R^3 (with prescribed normal direction of one of the planes) in time O(n^7/3).

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. acknowledged_ssus: - _id: LifeSc - _id: Bio acknowledgement: "We gratefully acknowledge the Lab Support Facility (LSF) and the Imaging and Optics Facility (IOF) (both of ISTA) and the Hounsfield CT Facility (University of Nottingham) for support with imaging and the Growth Facility (IPMB) for plant cultivation.

Auxin signaling acts as a central regulatory hub in this process, yet the mechanisms that dynamically tune early auxin signalling in real time remain unknown. Here, we used the light-gated, Ca2+-permeable Channelrhodopsin 2 variant XXM2.0 to optogenetically impose defined Ca2+ signatures on Arabidopsis root cells. Repetitive light activation triggered cytosolic Ca2+ signals that in turn suppressed auxin-induced membrane depolarization and Ca2+ transients. Moreover, prolonged optogenetic Ca2+ stimulation affects auxin-responsive transcriptional reprogramming. As phenotypic output, reversible inhibition of root growth by suppressing cell division and elongation was observed. We further identify a candidate CaM7–CNGC14 module that likely mediates Ca2+-dependent gating of early auxin signalling. Our study thus introduces a synthetic biology approach to decompose calcium–auxin crosstalk in plant cells, and demonstrates that optogenetically imposed cytosolic Ca2+ signals act as dynamic regulators of auxin susceptibility in roots. acknowledgement: "We would like to thank Dirk Becker (University of Wuerzburg) for his help in making the optogenetic constructs and for his comments on the manuscript.

Decades-long efforts yielded TF-DNA interaction models that predict how strongly an individual TF binds arbitrary DNA sequences and how individual binding events on the CRE combine to affect gene expression. These insights can be synthesized into a global, biophysically realistic, and quantitative genotype–phenotype map for gene regulation, a ‘holy grail’ for the application of evolutionary theory. A global map provides a rare opportunity to simulate the long-term evolution of regulatory sequences and pose several fundamental questions: How long does it take to evolve CREs de novo? How many non-trivial regulatory functions exist in sequence space? How connected are they? For which regulatory architecture is CRE evolution most rapid and evolvable?

However, how sRNAs exert their function is largely unknown, likely due to their typical origin in non-genic regions, the lack of distinct gene targets, and the sparse characterization of their associated Argonaute (AGO) effector proteins. Here we show that Arabidopsis male reproductive sRNAs associate with AGO4, 5, 6 and 9, all of which are enriched in meiocytes along with RNA Polymerase V (Pol V). This enables these sRNAs to methylate loci with imperfect sequence homology. AGO4, AGO6 and AGO9 predominantly load 24-nucleotide (nt) Pol IV-derived sRNAs and mediate DNA methylation in meiocytes in a dosage-dependent manner. Despite closer homology to microRNA-associated AGO1 and AGO10, AGO5 primarily binds CLSY3- and Pol IV-derived 21-24 nt sRNAs. Transcriptomic and methylomic analyses of meiocytes from single and compound ago mutants demonstrate distinct yet complementary roles of AGO4/6/9 and AGO5 in regulating protein-coding genes and silencing transposons in the germline. These molecular disruptions are accompanied by significant meiotic defects. Together, our findings reveal how AGO4/6/9-mediated DNA methylation and AGO5, likely acting through post-transcriptional gene silencing, work together to promote male germline development. acknowledgement: We thank Michael J. Axtell for generously sharing ago4-4 ago6-2, ago6-2 ago9-1 double and ago4-4 ago6-2 ago9-1 triple mutants.

We investigate how magnetization, flickering jet power and the interplay between them affects the morphology of radio galaxies. We present a grid of relativistic magnetohydrodynamic simulations using the pluto code covering constant and variable jets with two levels of magnetization. We find that the constant high-magnetization jets can lead to highly asymmetrical cocoon morphologies, while the variable high-magnetization jet can exhibit a broken morphology, caused by a discontinuous jet beam. Our work highlights the importance of magnetization and variability on the stability and resulting morphology of radio-loud AGN jets, suggesting both are significant factors in addition to jet power or environment. Furthermore, we show that the interaction between magnetization and variability can lead to the development of localized kink instabilities along the jet beam. Finally, we discuss the effects of hydrodynamic mixing in low-magnetization jets and the role of viewing-angle dependence in comparisons between our simulations and observed sources. To facilitate this comparison we present a library of simulated radio images at different times in the simulations and from various viewing angles, which highlight a diverse set of complex morphologies. acknowledgement: 'JHM and ELE acknowledge funding from a Royal Society University Research Fellowship (URF\R1\221062).

Across scales, \r\ngeometry plays a central role: the shape of active units and the structure of their environment \r\nstrongly influence how order emerges in these far-from-equilibrium systems. In this thesis, \r\nwe combine minimal active-matter models with bottom-up in vitro experiments to identify \r\nthe principles by which geometry and activity shape collective behavior in biological matter. \r\nAt the subcellular scale, we investigate how the physical properties of chiral FtsZ filaments \r\ngovern their large-scale organization. Using a mesoscopic model validated by reconstituted \r\nfilament assays, we show that filament shape, intrinsic curvature, and flexibility, together with \r\nactivity-driven straightening, determine whether filaments form chiral rings, polar bands, or \r\nnematic-like states. Our model shows that small changes in filament mechanics produce large \r\nshifts in collective structures, revealing how the geometry of individual filaments amplifies \r\nthrough activity to control patterns relevant for bacterial cytokinesis. \r\nAt the cellular scale, we examine how geometry of the external environment influences \r\ncollective cancer cell migration. Experiments in controlled microfabricated obstacle \r\nenvironments demonstrate that geometric disorder alone can induce a transition from \r\ncollective to single-cell invasion. A minimal model of active particles in disordered geometries \r\nreproduces these effects, demonstrating that cell dissemination results both from local \r\ngeometrical constraints and a global integration of spatial disorder over time. Surprisingly, \r\nthis transition is accompanied by a change in the universality class of interface dynamics, \r\nrevealing that cell-environment interactions can shift the collective behavior of an invasive \r\nfront purely through mechanics. \r\nIn the last system, we study how cell-intrinsic geometry and chirality affect collective motion \r\nin confined and unconfined settings. Using a minimal model inspired by in vitro experiments, \r\nwe analyze motile cells that exhibit persistent rotation due to intrinsic left-right asymmetry. \r\nIn circular confinement, this simplified chiral model reproduces several experimentally \r\nobserved features within specific parameter regimes. At high densities in unconfined \r\nenvironments, however, intrinsic chirality becomes masked even before the onset of the \r\njamming transition. These results show that single-cell geometric asymmetry does not \r\nnecessarily translate into large-scale chiral flows, offering new insight into how forces and \r\nsymmetries shape collective motion in dense cellular systems. \r\nOverall, this work uncovers how geometric constraints – embedded in the intrinsic \r\narchitecture of an active filament or encoded in the complexity of a microenvironment \r\ncouple to active forces to generate different classes of complex behaviors.

[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.

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).

A potential realization necessitates systems with low-frequency dynamics at an optimal mass scale, for which the microgram-to-milligram range is a strong contender. Here, after refining a figure-of-merit for the problem, we present a 1-milligram torsional pendulum operating at 18 Hz. We demonstrate laser cooling its motion from room temperature to 240~microkelvins, surpassing by over 20-fold the coldest motions attained for oscillators ranging from micrograms to kilograms. We quantify and contrast the utility of the current approach with other platforms. The achieved performance and large improvement potential highlight milligram-scale torsional pendulums as a powerful platform for precision measurements relevant to future studies at the quantum-gravity interface. article_processing_charge: No author: - first_name: Sofya full_name: Agafonova, Sofya id: 09501ff6-dca7-11ea-a8ae-b3e0b9166e80 last_name: Agafonova orcid: 0000-0003-0582-2946 citation: ama: 'Agafonova S.
