Significant work has gone towards investigating majority or consensus dynamics in this model: that is, assuming that every node is initially in one of two states X or Y, determine which state had higher initial count.\r\n\r\nIn this paper, we consider a natural generalization of majority/consensus, which we call comparison : in its simplest formulation, we are given two baseline states, X and Y, present in any initial configuration in fixed, but possibly small counts. One of these states has higher count than the other: we will assume |X_0| > C |Y_0| for some constant C > 1. The challenge is to design a protocol by which nodes can quickly and reliably decide on which of the baseline states X_0 and Y_0 has higher initial count. We begin by analyzing a simple and general dynamics solving the above comparison problem, which uses O( log n ) states per node, and converges in O(log n) (parallel) time, with high probability, to a state where the whole population votes on opinions X or Y at rates proportional to the initial concentrations of |X_0| vs. |Y_0|. We then describe how this procedure can be bootstrapped to solve comparison, i.e. have every node in the population reach the \"correct'' decision, with probability 1 - o(1), at the cost of O (log log n) additional states. Further, we prove that this dynamics is self-stabilizing, in the sense that it converges to the correct decision from arbitrary initial states, and leak-robust, in the sense that it can withstand spurious faulty reactions, which are known to occur in practical implementations of population protocols. Our analysis is based on a new martingale concentration result relating the discrete-time evolution of a population protocol to its expected (steady-state) analysis, which should be a useful tool when analyzing opinion dynamics and epidemic dissemination in the population model."}],"title":"Comparison dynamics in population protocols","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","fulldoi":"https://doi.org/10.1145/3465084.3467915","conference":{"location":"Virtual, Italy","end_date":"2021-07-30","name":"PODC: Symposium on Principles of Distributed Computing","start_date":"2021-07-26"},"publication_status":"published","date_created":"2021-08-22T22:01:20Z","day":"21","scopus_import":"1","language":[{"iso":"eng"}],"oa_version":"None","_id":"9951","author":[{"first_name":"Dan-Adrian","full_name":"Alistarh, Dan-Adrian","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","last_name":"Alistarh","orcid":"0000-0003-3650-940X"},{"id":"4B865388-F248-11E8-B48F-1D18A9856A87","last_name":"Töpfer","first_name":"Martin","full_name":"Töpfer, Martin"},{"last_name":"Uznański","first_name":"Przemysław","full_name":"Uznański, Przemysław"}],"page":"55-65","quality_controlled":"1","isi":1,"citation":{"ama":"Alistarh D-A, Töpfer M, Uznański P.

Spindle positioning has been extensively studied in cells dividing in two-dimensional (2D) environments and in epithelial tissues, where proteins such as NuMA (also known as NUMA1) orient division along the interphase long axis of the cell. However, little is known about how cells control spindle positioning in three-dimensional (3D) environments, such as early mammalian embryos and a variety of adult tissues. Here, we use mouse embryonic stem cells (ESCs), which grow in 3D colonies, as a model to investigate division in 3D. We observe that, at the periphery of 3D colonies, ESCs display high spindle mobility and divide asymmetrically. Our data suggest that enhanced spindle movements are due to unequal distribution of the cell–cell junction protein E-cadherin between future daughter cells. Interestingly, when cells progress towards differentiation, division becomes more symmetric, with more elongated shapes in metaphase and enhanced cortical NuMA recruitment in anaphase. Altogether, this study suggests that in 3D contexts, the geometry of the cell and its contacts with neighbors control division orientation and symmetry."}],"title":"Three-dimensional geometry controls division symmetry in stem cell colonies","intvolume":"       134","has_accepted_license":"1","type":"journal_article","article_processing_charge":"Yes (in subscription journal)","issue":"14","acknowledgement":"We would like to thank the entire Paluch and Baum laboratories at the MRC-LMCB and the Chalut lab at the Cambridge SCI for discussions and feedback throughout the project, and the MRC-LMCB microscopy platform, in particular Andrew Vaughan, for technical support.","article_number":"jcs255018","author":[{"first_name":"Agathe","full_name":"Chaigne, Agathe","last_name":"Chaigne"},{"first_name":"Matthew B.","full_name":"Smith, Matthew B.","last_name":"Smith"},{"last_name":"Cavestany","full_name":"Cavestany, R.

Chronic stress can influence all organs via the secretion of stress hormones, including glucocorticoids by the adrenal glands, which coordinate the stress response across the body. In the brain, glucocorticoid receptors (GR) are expressed by various cell types including microglia, which are its resident immune cells regulating stress-induced inflammatory processes. To study the roles of microglial GR under normal homeostatic conditions and following chronic stress, we generated a mouse model in which the GR gene is depleted in microglia specifically at adulthood to prevent developmental confounds. We first confirmed that microglia were depleted in GR in our model in males and females among the cingulate cortex and the hippocampus, both stress-sensitive brain regions. Then, cohorts of microglial-GR depleted and wild-type (WT) adult female mice were housed for 3 weeks in a standard or stressful condition, using a chronic unpredictable mild stress (CUMS) paradigm. CUMS induced stress-related behavior in both microglial-GR depleted and WT animals as demonstrated by a decrease of both saccharine preference and progressive ratio breakpoint. Nevertheless, the hippocampal microglial and neural mechanisms underlying the adaptation to stress occurred differently between the two genotypes. Upon CUMS exposure, microglial morphology was altered in the WT controls, without any apparent effect in microglial-GR depleted mice. Furthermore, in the standard environment condition, GR depleted-microglia showed increased expression of pro-inflammatory genes, and genes involved in microglial homeostatic functions (such as Trem2, Cx3cr1 and Mertk). On the contrary, in CUMS condition, GR depleted-microglia showed reduced expression levels of pro-inflammatory genes and increased neuroprotective as well as anti-inflammatory genes compared to WT-microglia. Moreover, in microglial-GR depleted mice, but not in WT mice, CUMS led to a significant reduction of CA1 long-term potentiation and paired-pulse ratio. Lastly, differences in adult hippocampal neurogenesis were observed between the genotypes during normal homeostatic conditions, with microglial-GR deficiency increasing the formation of newborn neurons in the dentate gyrus subgranular zone independently from stress exposure. Together, these findings indicate that, although the deletion of microglial GR did not prevent the animal’s ability to respond to stress, it contributed to modulating hippocampal functions in both standard and stressful conditions, notably by shaping the microglial response to chronic stress.","lang":"eng"}],"year":"2021","publication":"Brain, Behavior, and Immunity","date_updated":"2023-10-03T09:49:18Z","month":"10"},{"_id":"9957","scopus_import":"1","language":[{"iso":"eng"}],"oa_version":"Preprint","date_created":"2021-08-24T06:03:00Z","day":"01","ddc":["000"],"oa":1,"publication_status":"published","conference":{"end_date":"2021-06-25","location":"Nashville, TN, United States; Virtual","start_date":"2021-06-20","name":"CVPR: Conference on Computer Vision and Pattern Recognition"},"fulldoi":"https://doi.org/10.1109/CVPR46437.2021.00476","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","doi":"10.1109/CVPR46437.2021.00476","file_date_updated":"2021-08-24T06:02:15Z","department":[{"_id":"BeBi"}],"date_published":"2021-09-01T00:00:00Z","external_id":{"isi":["000739917304096"],"arxiv":["2008.10247"]},"publication_identifier":{"isbn":["978-166544509-2"],"issn":["1063-6919"]},"status":"public","publisher":"IEEE","quality_controlled":"1","isi":1,"citation":{"mla":"B R, Mallikarjun, et al. “Monocular Reconstruction of Neural Face Reflectance Fields.” <i>Proceedings of the IEEE Computer Society Conference on Computer Vision and Pattern Recognition</i>, IEEE, 2021, pp. 4791–800, doi:<a href=\"https://doi.org/10.1109/CVPR46437.2021.00476\">10.1109/CVPR46437.2021.00476</a>.","ista":"B R M, Tewari A, Oh T-H, Weyrich T, Bickel B, Seidel H-P, Pfister H, Matusik W, Elgharib M, Theobalt C. 2021.

Most existing methods for estimating the face reflectance from a monocular image assume faces to be diffuse with very few approaches adding a specular component. This still leaves out important perceptual aspects of reflectance as higher-order global illumination effects and self-shadowing are not modeled. We present a new neural representation for face reflectance where we can estimate all components of the reflectance responsible for the final appearance from a single monocular image. Instead of modeling each component of the reflectance separately using parametric models, our neural representation allows us to generate a basis set of faces in a geometric deformation-invariant space, parameterized by the input light direction, viewpoint and face geometry. We learn to reconstruct this reflectance field of a face just from a monocular image, which can be used to render the face from any viewpoint in any light condition. Our method is trained on a light-stage training dataset, which captures 300 people illuminated with 150 light conditions from 8 viewpoints. We show that our method outperforms existing monocular reflectance reconstruction methods, in terms of photorealism due to better capturing of physical premitives, such as sub-surface scattering, specularities, self-shadows and other higher-order effects.","lang":"eng"}],"year":"2021","publication":"Proceedings of the IEEE Computer Society Conference on Computer Vision and Pattern Recognition","file":[{"date_updated":"2021-08-24T06:02:15Z","file_name":"R_Monocular_Reconstruction_of_Neural_Face_Reflectance_Fields_CVPR_2021_paper[1].pdf","file_id":"9958","access_level":"open_access","file_size":4746649,"date_created":"2021-08-24T06:02:15Z","checksum":"961db0bde76dd87cf833930080bb9f38","content_type":"application/pdf","creator":"bbickel","relation":"main_file"}],"month":"09","arxiv":1,"date_updated":"2023-08-11T11:08:35Z"},{"type":"journal_article","article_processing_charge":"No","issue":"9","acknowledgement":"We thank Dmitry Abanin, Ehud Altman, Iris Cong, Sepehr Ebadi, Alex Keesling, Harry Levine, Ahmed Omran, Hannes Pichler, Rhine Samajdar, Guilia Semeghini, Tout Wang, Norman Yao, and Harry Zhou or stimulating discussions.

Recently, quench experiments in Rydberg atom arrays [Bluvstein et al. Science 371, 1355 (2021)] demonstrated that coherent revivals associated with quantum many-body scars can be stabilized by periodic driving, generating stable subharmonic responses over a wide parameter regime. We analyze a simple, related model where these phenomena originate from spatiotemporal ordering in an effective Floquet unitary, corresponding to discrete time-crystalline behavior in a prethermal regime. Unlike conventional discrete time crystals, the subharmonic response exists only for Néel-like initial states, associated with quantum scars. We predict robustness to perturbations and identify emergent timescales that could be observed in future experiments. Our results suggest a route to controlling entanglement in interacting quantum systems by combining periodic driving with many-body scars.","lang":"eng"}],"intvolume":"       127","title":"Discrete time-crystalline order enabled by quantum many-body scars: Entanglement steering via periodic driving","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","fulldoi":"https://doi.org/10.1103/PhysRevLett.127.090602","volume":127,"project":[{"grant_number":"850899","call_identifier":"H2020","_id":"23841C26-32DE-11EA-91FC-C7463DDC885E","name":"Non-Ergodic Quantum Matter: Universality, Dynamics and Control"}],"publication_status":"published","oa":1,"ec_funded":1,"day":"27","date_created":"2021-08-28T08:08:58Z","scopus_import":"1","language":[{"iso":"eng"}],"oa_version":"Submitted Version","_id":"9960","author":[{"last_name":"Maskara","first_name":"N.","full_name":"Maskara, N."},{"full_name":"Michailidis, Alexios","first_name":"Alexios","orcid":"0000-0002-8443-1064","last_name":"Michailidis","id":"36EBAD38-F248-11E8-B48F-1D18A9856A87"},{"first_name":"W.

On the ergodic side, Thouless energy decreases slowly with the system size, while at the transition it becomes comparable to the level spacing. Different probes yield consistent estimates of Thouless energy in their overlapping regime of applicability, giving the location of the transition point nearly free of finite-size drift.

However, during the discovery of cost-efficient routes for the transaction, critical information may be revealed about the transacting entities. This paper initiates the study of privacy-preserving route discovery mechanisms for payment channel networks. In particular, we present LightPIR, an approach which allows a client to learn the shortest (or cheapest in terms of fees) path between two nodes without revealing any information about the endpoints of the transaction to the servers. The two main observations which allow for an efficient solution in LightPIR are that: (1) surprisingly, hub labelling algorithms – which were developed to preprocess “street network like” graphs so one can later efficiently compute shortest paths – also perform well for the graphs underlying payment channel networks, and that (2) hub labelling algorithms can be conveniently combined with private information retrieval. LightPIR relies on a simple hub labeling heuristic on top of existing hub labeling algorithms which leverages the specific topological features of cryptocurrency networks to further minimize storage and bandwidth overheads. In a case study considering the Lightning network, we show that our approach is an order of magnitude more efficient compared to a privacy-preserving baseline based on using private information retrieval on a database that stores all pairs shortest paths."}],"year":"2021","arxiv":1,"date_updated":"2026-04-07T13:29:44Z","month":"06","article_processing_charge":"No","type":"conference"},{"_id":"9973","scopus_import":"1","oa_version":"Published Version","corr_author":"1","language":[{"iso":"eng"}],"date_created":"2021-08-30T10:07:44Z","day":"30","ddc":["621"],"ec_funded":1,"oa":1,"publication_status":"published","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"volume":387,"project":[{"name":"IST Austria Open Access Fund","_id":"B67AFEDC-15C9-11EA-A837-991A96BB2854"},{"grant_number":"754411","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"},{"grant_number":"F6504","_id":"fc31cba2-9c52-11eb-aca3-ff467d239cd2","name":"Taming Complexity in Partial Differential Systems"}],"fulldoi":"https://doi.org/10.1007/s00220-021-04199-4","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","keyword":["Mathematical Physics","Statistical and Nonlinear Physics"],"doi":"10.1007/s00220-021-04199-4","file_date_updated":"2021-09-08T09:46:34Z","department":[{"_id":"JaMa"}],"article_type":"original","date_published":"2021-08-30T00:00:00Z","publication_identifier":{"issn":["0010-3616"],"eissn":["1432-0916"]},"external_id":{"pmid":["34776525"],"arxiv":["2007.13506"],"isi":["000691214200001"]},"status":"public","publisher":"Springer Nature","quality_controlled":"1","isi":1,"citation":{"ieee":"M.

For mediators to work efficiently they need to oxidize the solid with fast kinetics yet the lowest possible overpotential. Here, we found that when the redox potentials of mediators are tuned via, e.g., Li + concentration in the electrolyte, they exhibit distinct threshold potentials, where the kinetics accelerate several-fold within a range as small as 10 mV. This phenomenon is independent of types of mediators and electrolyte. The acceleration originates from the overpotentials required to activate fast Li + /e – extraction and the following chemical step at specific abundant surface facets. Efficient redox catalysis at insulating solids requires therefore carefully considering the surface conditions of the storage materials and electrolyte-dependent redox potentials, which may be tuned by salt concentrations or solvents.","lang":"eng"}],"related_material":{"record":[{"id":"10813","relation":"later_version","status":"public"}]},"title":"Sharp kinetic acceleration potentials during mediated redox catalysis of insulators","has_accepted_license":"1","date_updated":"2024-10-09T21:01:46Z","file":[{"file_name":"2021_ResearchSquare_Cao.pdf","date_updated":"2021-08-31T14:02:19Z","access_level":"open_access","file_id":"9979","date_created":"2021-08-31T14:02:19Z","file_size":1019662,"content_type":"application/pdf","checksum":"1878e91c29d5769ed5a827b0b7addf00","creator":"cchlebak","relation":"main_file","success":1}],"month":"08","publication":"Research Square","acknowledgement":"This work was financially supported by the National Natural Science Foundation of China (51773092, 21975124, 11874254, 51802187, U2030206).

Typically Li2S formation is explained by direct electroreduction of a PS to Li2S; however, this is not consistent with the size of the insulating Li2S deposits. Here, we use in situ small and wide angle X-ray scattering (SAXS/WAXS) to track the growth and dissolution of crystalline and amorphous deposits from atomic to sub-micron scales during charge and discharge. Stochastic modelling based on the SAXS data allows quantification of the chemical phase evolution during discharge and charge. We show that Li2S deposits predominantly via disproportionation of transient, solid Li2S2 to form primary Li2S crystallites and solid Li2S4 particles. We further demonstrate that this process happens in reverse during charge. These findings show that the discharge capacity and rate capability in Li-S battery cathodes are therefore limited by mass transport through the increasingly tortuous network of Li2S / Li2S4 / carbon pores rather than electron transport through a passivating surface film."}],"main_file_link":[{"url":"https://www.researchsquare.com/article/rs-818607/v1","open_access":"1"}],"status":"public","author":[{"last_name":"Prehal","first_name":"Christian","full_name":"Prehal, Christian"},{"last_name":"Talian","full_name":"Talian, Sara Drvarič","first_name":"Sara Drvarič"},{"last_name":"Vizintin","full_name":"Vizintin, Alen","first_name":"Alen"},{"last_name":"Amenitsch","first_name":"Heinz","full_name":"Amenitsch, Heinz"},{"last_name":"Dominko","first_name":"Robert","full_name":"Dominko, Robert"},{"first_name":"Stefan Alexander","full_name":"Freunberger, Stefan Alexander","id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","last_name":"Freunberger","orcid":"0000-0003-2902-5319"},{"first_name":"Vanessa","full_name":"Wood, Vanessa","last_name":"Wood"}],"page":"21","date_updated":"2021-12-03T10:35:42Z","month":"08","citation":{"mla":"Prehal, Christian, et al. “Mechanism of Li2S Formation and Dissolution in Lithium-Sulphur Batteries.” <i>Research Square</i>, doi:<a href=\"https://doi.org/10.21203/rs.3.rs-818607/v1\">10.21203/rs.3.rs-818607/v1</a>.","ista":"Prehal C, Talian SD, Vizintin A, Amenitsch H, Dominko R, Freunberger SA, Wood V.

Although a number of promising numerical methods exist, they often have limited applicability due to the growth of entanglement or the presence of the so-called sign problem. In this work, we develop an importance sampling scheme for the simulation of quantum spin dynamics, building on a recent approach mapping quantum spin systems to classical stochastic processes. The importance sampling scheme is based on identifying the classical trajectory that yields the largest contribution to a given quantum observable. An exact transformation is then carried out to preferentially sample trajectories that are close to the dominant one. We demonstrate that this approach is capable of reducing the temporal growth of fluctuations in the stochastic quantities, thus extending the range of accessible times and system sizes compared to direct sampling. We discuss advantages and limitations of the proposed approach, outlining directions\r\nfor further developments.","lang":"eng"}],"year":"2021","publication":"SciPost Physics","arxiv":1,"date_updated":"2025-05-14T10:51:45Z","file":[{"date_updated":"2021-09-02T14:05:43Z","file_name":"2021_SciPostPhys_DeNicola.pdf","file_id":"9984","access_level":"open_access","file_size":373833,"date_created":"2021-09-02T14:05:43Z","checksum":"e4ec69d893e31811efc6093cb6ea8eb7","content_type":"application/pdf","creator":"cchlebak","relation":"main_file","success":1}],"month":"09","article_number":"048","issue":"3","article_processing_charge":"No","type":"journal_article"},{"publication":"Nature Communications","file":[{"date_updated":"2021-09-08T12:57:06Z","file_name":"2021_NatureCommunications_Watson.pdf","file_id":"9991","access_level":"open_access","file_size":18310502,"date_created":"2021-09-08T12:57:06Z","checksum":"1bf4f6a561f96bc426d754de9cb57710","content_type":"application/pdf","creator":"cchlebak","relation":"main_file","success":1}],"month":"08","date_updated":"2023-08-11T11:07:51Z","has_accepted_license":"1","title":"AMPA receptor anchoring at CA1 synapses is determined by N-terminal domain and TARP γ8 interactions","intvolume":"        12","abstract":[{"text":"AMPA receptor (AMPAR) abundance and positioning at excitatory synapses regulates the strength of transmission. Changes in AMPAR localisation can enact synaptic plasticity, allowing long-term information storage, and is therefore tightly controlled. Multiple mechanisms regulating AMPAR synaptic anchoring have been described, but with limited coherence or comparison between reports, our understanding of this process is unclear. Here, combining synaptic recordings from mouse hippocampal slices and super-resolution imaging in dissociated cultures, we compare the contributions of three AMPAR interaction domains controlling transmission at hippocampal CA1 synapses. We show that the AMPAR C-termini play only a modulatory role, whereas the extracellular N-terminal domain (NTD) and PDZ interactions of the auxiliary subunit TARP γ8 are both crucial, and each is sufficient to maintain transmission. Our data support a model in which γ8 accumulates AMPARs at the postsynaptic density, where the NTD further tunes their positioning.

The phytohormone auxin is a vital growth regulator with central importance for differential growth control. Our results indicate that auxin-reliant growth programs affect the molecular complexity of xyloglucans, the major type of cell wall hemicellulose in eudicots. Auxin-dependent induction and repression of growth coincide with reduced and enhanced molecular complexity of xyloglucans, respectively. In agreement with a proposed function in growth control, genetic interference with xyloglucan side decorations distinctly modulates auxin-dependent differential growth rates. Our work proposes that auxin-dependent growth programs have a spatially defined effect on xyloglucan’s molecular structure, which in turn affects cell wall mechanics and specifies differential, gravitropic hypocotyl growth."}],"article_processing_charge":"Yes","pmid":1,"type":"journal_article","article_number":"9222","issue":"17","acknowledgement":"We are grateful to Paul Knox, Markus Pauly, Malcom O’Neill, and Ignacio Zarra for providing published material; the BOKU-VIBT Imaging Center for access and M.

As scheduling non-determinism creates exponentially large spaces of thread interleavings, SMC attempts to partition this space into equivalence classes and explore only a few representatives from each class. The efficiency of this approach depends on two factors: (a) the coarseness of the partitioning, and (b) the time to generate representatives in each class. For this reason, the search for coarse partitionings that are efficiently explorable is an active research challenge. In this work we present   RVF-SMC , a new SMC algorithm that uses a novel reads-value-from (RVF) partitioning. Intuitively, two interleavings are deemed equivalent if they agree on the value obtained in each read event, and read events induce consistent causal orderings between them. The RVF partitioning is provably coarser than recent approaches based on Mazurkiewicz and “reads-from” partitionings. Our experimental evaluation reveals that RVF is quite often a very effective equivalence, as the underlying partitioning is exponentially coarser than other approaches. Moreover,   RVF-SMC  generates representatives very efficiently, as the reduction in the partitioning is often met with significant speed-ups in the model checking task."}],"year":"2021","has_accepted_license":"1","title":"Stateless model checking under a reads-value-from equivalence","related_material":{"record":[{"status":"public","relation":"dissertation_contains","id":"10199"}]},"publication":"33rd International Conference on Computer-Aided Verification ","file":[{"file_id":"11368","access_level":"open_access","date_updated":"2022-05-13T07:00:20Z","file_name":"2021_LNCS_Agarwal.pdf","success":1,"relation":"main_file","creator":"dernst","content_type":"application/pdf","checksum":"4b346e5fbaa8b9bdf107819c7b2aadee","file_size":1516756,"date_created":"2022-05-13T07:00:20Z"}],"month":"07","alternative_title":["LNCS"],"date_updated":"2026-04-08T07:00:30Z","arxiv":1},{"status":"public","publisher":"Springer Nature","citation":{"apa":"Koroteev, P., Pushkar, P., Smirnov, A.

Here we uncovered a progenitor cell allocation mechanism that stems from an incomplete process of epithelial delamination that allows progenitors to coordinate their movement with adjacent extra-embryonic tissues. Progenitors of the zebrafish laterality organ originate from the surface epithelial enveloping layer by an apical constriction process of cell delamination. During this process, progenitors retain long-term apical contacts that enable the epithelial layer to pull a subset of progenitors along their way towards the vegetal pole. The remaining delaminated progenitors follow apically-attached progenitors’ movement by a co-attraction mechanism, avoiding sequestration by the adjacent endoderm, ensuring their fate and collective allocation at the differentiation site. Thus, we reveal that incomplete delamination serves as a cellular platform for coordinated tissue movements during development.

The three-dimensional shape of a woven structure emerges through a complex interplay of the elastic bending behavior of the ribbons and the contact forces at their crossings. Curvature can be injected by carefully placing topological singularities in the otherwise regular weaving pattern. However, shape control through topology is highly non-trivial and inherently discrete, which severely limits the range of attainable woven geometries. Here, we demonstrate how to construct arbitrary smooth free-form surface geometries by weaving carefully optimized curved ribbons. We present an optimization-based approach to solving the inverse design problem for such woven structures. Our algorithm computes the ribbons' planar geometry such that their interwoven assembly closely approximates a given target design surface in equilibrium. We systematically validate our approach through a series of physical prototypes to show a broad range of new woven geometries that is not achievable by existing methods. We anticipate our computational approach to significantly enhance the capabilities for the design of new woven structures. Facilitated by modern digital fabrication technology, we see potential applications in material science, bio- and mechanical engineering, art, design, and architecture.","lang":"eng"}],"article_processing_charge":"No","extern":"1","type":"journal_article","issue":"4","publisher":"Association for Computing Machinery","status":"public","page":"1-15","author":[{"full_name":"Ren, Yingying","first_name":"Yingying","last_name":"Ren","id":"93d68d10-3540-11ef-a265-f748a50dba3d"},{"last_name":"Panetta","first_name":"Julian","full_name":"Panetta, Julian"},{"last_name":"Chen","full_name":"Chen, Tian","first_name":"Tian"},{"first_name":"Florin","full_name":"Isvoranu, Florin","last_name":"Isvoranu"},{"full_name":"Poincloux, Samuel","first_name":"Samuel","last_name":"Poincloux"},{"full_name":"Brandt, Christopher","first_name":"Christopher","last_name":"Brandt"},{"full_name":"Martin, Alison","first_name":"Alison","last_name":"Martin"},{"last_name":"Pauly","full_name":"Pauly, Mark","first_name":"Mark"}],"quality_controlled":"1","citation":{"ama":"Ren Y, Panetta J, Chen T, et al. 3D weaving with curved ribbons. <i>ACM Transactions on Graphics</i>. 2021;40(4):1-15. doi:<a href=\"https://doi.org/10.1145/3450626.3459788\">10.1145/3450626.3459788</a>","ista":"Ren Y, Panetta J, Chen T, Isvoranu F, Poincloux S, Brandt C, Martin A, Pauly M. 2021. 3D weaving with curved ribbons.

We define bounce rules governing how the robot should reorient after reaching a boundary, such as reorienting relative to its heading prior to collision, or relative to the normal of the boundary. We then generate plans as sequences of rules, using the bounce visibility graph generated from a polygonal environment definition, while assuming we have unavoidable non-determinism in our actuation. Our planner can be queried to determine the feasibility of tasks such as reaching goal sets and patrolling (repeatedly visiting a sequence of goals). If the task is found feasible, the planner provides a sequence of non-deterministic interaction rules, which also provide information on how precisely the robot must execute the plan to succeed. We also show how to compute stable cyclic trajectories and use these to limit uncertainty in the robot’s position. </jats:p>","lang":"eng"}],"year":"2021","intvolume":"        40","title":"A visibility-based approach to computing non-deterministic bouncing strategies","fulldoi":"https://doi.org/10.1177/0278364921992788","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"publication_status":"published","volume":40,"day":"01","date_created":"2024-08-12T10:01:27Z","_id":"17422","scopus_import":"1","oa_version":"Published Version","language":[{"iso":"eng"}],"quality_controlled":"1","citation":{"ama":"Nilles AQ, Ren Y, Becerra I, LaValle SM.

In this paper, we propose a new approach to this problem: a type system we call RefinedC, which combines ownership types (for modular reasoning about shared state and concurrency) with refinement types (for encoding precise invariants on C data types and Hoare-style specifications for C functions).\r\nRefinedC is both automated (requiring minimal user intervention) and foundational (producing a proof of program correctness in Coq), while at the same time handling a range of low-level programming idioms such as pointer arithmetic. In particular, following the approach of RustBelt, the soundness of the RefinedC type system is justified semantically by interpretation into the Coq-based Iris framework for higher-order concurrent separation logic. However, the typing rules of RefinedC are also designed to be encodable in a new “separation logic programming” language we call Lithium. By restricting to a carefully chosen (yet expressive) fragment of separation logic, Lithium supports predictable, automatic, goal-directed proof search without backtracking. We demonstrate the effectiveness of RefinedC on a range of representative examples of C code."}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1145/3453483.3454036"}],"doi":"10.1145/3453483.3454036","title":"RefinedC: Automating the foundational verification of C code with refined ownership types","page":"158-174","date_updated":"2024-09-10T11:54:22Z","author":[{"last_name":"Sammler","id":"510d3901-2a03-11ee-914d-d9ae9011f0a7","full_name":"Sammler, Michael Joachim","first_name":"Michael Joachim"},{"first_name":"Rodolphe","full_name":"Lepigre, Rodolphe","last_name":"Lepigre"},{"last_name":"Krebbers","first_name":"Robbert","full_name":"Krebbers, Robbert"},{"full_name":"Memarian, Kayvan","first_name":"Kayvan","last_name":"Memarian"},{"full_name":"Dreyer, Derek","first_name":"Derek","last_name":"Dreyer"},{"last_name":"Garg","first_name":"Deepak","full_name":"Garg, Deepak"}],"month":"06","citation":{"short":"M.J.

It addresses the science case and some implementation issues of a space-borne radio interferometric system for ultra-sharp imaging of celestial radio sources at the level of angular resolution down to (sub-) microarcseconds. THEZA focuses at millimetre and sub-millimetre wavelengths (frequencies above \r\n300 GHz), but allows for science operations at longer wavelengths too. The THEZA concept science rationale is focused on the physics of spacetime in the vicinity of supermassive black holes as the leading science driver. The main aim of the concept is to facilitate a major leap by providing researchers with orders of magnitude improvements in the resolution and dynamic range in direct imaging studies of the most exotic objects in the Universe, black holes. The concept will open up a sizeable range of hitherto unreachable parameters of observational astrophysics. It unifies two major lines of development of space-borne radio astronomy of the past decades: Space VLBI (Very Long Baseline Interferometry) and mm- and sub-mm astrophysical studies with “single dish” instruments. It also builds upon the recent success of the Earth-based Event Horizon Telescope (EHT) – the first-ever direct image of a shadow of the super-massive black hole in the centre of the galaxy M87. As an amalgam of these three major areas of modern observational astrophysics, THEZA aims at facilitating a breakthrough in high-resolution high image quality studies in the millimetre and sub-millimetre domain of the electromagnetic spectrum."}]}]
