Our main contribution is a homogenisation result that describes the effective behaviour of the discrete problems in terms of a continuous optimal transport problem. The effective energy density can be explicitly expressed in terms of a cell formula, which is a finite-dimensional convex programming problem that depends non-trivially on the local geometry of the discrete graph and the discrete energy density. Our homogenisation result is derived from a Γ\r\n-convergence result for action functionals on curves of measures, which we prove under very mild growth conditions on the energy density. We investigate the cell formula in several cases of interest, including finite-volume discretisations of the Wasserstein distance, where non-trivial limiting behaviour occurs."}],"doi":"10.1007/s00526-023-02472-z","intvolume":"        62","corr_author":"1","day":"28","quality_controlled":"1","citation":{"chicago":"Gladbach, Peter, Eva Kopfer, Jan Maas, and Lorenzo Portinale. “Homogenisation of Dynamical Optimal Transport on Periodic Graphs.” <i>Calculus of Variations and Partial Differential Equations</i>.

A natural way to approximate a smooth isomanifold M=f−1(0) is to consider its piecewise linear (PL) approximation M^\r\n based on a triangulation T of the ambient space Rd. In this paper, we describe a simple algorithm to trace isomanifolds from a given starting point. The algorithm works for arbitrary dimensions n and d, and any precision D. Our main result is that, when f (or M) has bounded complexity, the complexity of the algorithm is polynomial in d and δ=1/D (and unavoidably exponential in n). Since it is known that for δ=Ω(d2.5), M^ is O(D2)-close and isotopic to M\r\n, our algorithm produces a faithful PL-approximation of isomanifolds of bounded complexity in time polynomial in d. Combining this algorithm with dimensionality reduction techniques, the dependency on d in the size of M^ can be completely removed with high probability. We also show that the algorithm can handle isomanifolds with boundary and, more generally, isostratifolds. The algorithm for isomanifolds with boundary has been implemented and experimental results are reported, showing that it is practical and can handle cases that are far ahead of the state-of-the-art.

This “octave equivalence” is critical to perception and production of music and speech and occurs early in human development. Because it also occurs cross-culturally, a biological basis of octave equivalence has been hypothesized. Members of our team previousy suggested four human traits are at the root of this phenomenon: (1) vocal learning, (2) clear octave information in vocal harmonics, (3) differing vocal ranges, and (4) vocalizing together. Using cross-species studies, we can test how relevant these respective traits are, while controlling for enculturation effects and addressing questions of phylogeny. Common marmosets possess forms of three of the four traits, lacking differing vocal ranges. We tested 11 common marmosets by adapting an established head-turning paradigm, creating a parallel test to an important infant study. Unlike human infants, marmosets responded similarly to tones shifted by an octave or other intervals. Because previous studies with the same head-turning paradigm produced differential results to discernable acoustic stimuli in common marmosets, our results suggest that marmosets do not perceive octave equivalence. Our work suggests differing vocal ranges between adults and children and men and women and the way they are used in singing together may be critical to the development of octave equivalence.","lang":"eng"}],"doi":"10.1111/desc.13395","intvolume":"        26","day":"01","quality_controlled":"1","date_created":"2023-05-14T22:01:00Z","citation":{"ama":"Wagner B, Šlipogor V, Oh J, Varga M, Hoeschele M.

Nowadays, it can also be performed via automated machines that weave threads with high spatial accuracy. A characteristic feature of the appearance of the threads is a high degree of anisotropy. The anisotropic behavior is caused by depositing thin but long strings of thread. As a result, the stitched patterns convey both color and direction. Artists leverage this anisotropic behavior to enhance pure color images with textures, illusions of motion, or depth cues. However, designing colorful embroidery patterns with prescribed directionality is a challenging task, one usually requiring an expert designer. In this work, we propose an interactive algorithm that generates machine-fabricable embroidery patterns from multi-chromatic images equipped with user-specified directionality fields.We cast the problem of finding a stitching pattern into vector theory. To find a suitable stitching pattern, we extract sources and sinks from the divergence field of the vector field extracted from the input and use them to trace streamlines. We further optimize the streamlines to guarantee a smooth and connected stitching pattern. The generated patterns approximate the color distribution constrained by the directionality field. To allow for further artistic control, the trade-off between color match and directionality match can be interactively explored via an intuitive slider. We showcase our approach by fabricating several embroidery paths.","lang":"eng"}],"oa":1,"file_date_updated":"2023-05-16T08:28:37Z"},{"month":"07","project":[{"grant_number":"M03319","name":"Perception-Aware Appearance Fabrication","_id":"eb901961-77a9-11ec-83b8-f5c883a62027"}],"keyword":["reinforcement learning","deposition","control","color","multi-filament"],"oa_version":"Submitted Version","publication_status":"published","publisher":"IEEE","type":"conference","_id":"12976","publication_identifier":{"eisbn":["9798350323658"],"issn":["1050-4729"]},"isi":1,"date_updated":"2025-04-15T07:43:52Z","title":"Learning deposition policies for fused multi-material 3D printing","department":[{"_id":"BeBi"}],"author":[{"first_name":"Kang","last_name":"Liao","full_name":"Liao, Kang"},{"first_name":"Thibault","last_name":"Tricard","full_name":"Tricard, Thibault"},{"id":"62E473F4-5C99-11EA-A40E-AF823DDC885E","last_name":"Piovarci","orcid":"0000-0002-5062-4474","full_name":"Piovarci, Michael","first_name":"Michael"},{"first_name":"Hans-Peter","last_name":"Seidel","full_name":"Seidel, Hans-Peter"},{"last_name":"Babaei","full_name":"Babaei, Vahid","first_name":"Vahid"}],"external_id":{"isi":["001048371104068"]},"volume":2023,"date_published":"2023-07-04T00:00:00Z","file":[{"creator":"mpiovarc","file_id":"12977","relation":"main_file","date_updated":"2023-05-16T09:12:05Z","checksum":"daeaa67124777d88487f933ea3f77164","content_type":"application/pdf","access_level":"open_access","date_created":"2023-05-16T09:12:05Z","success":1,"file_name":"Liao2023.pdf","file_size":5367986}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","acknowledgement":"This work is graciously supported by FWF Lise Meitner (Grant M 3319).

An important shortcoming of this type of technology is its limited multi-material capabilities. While there are simple hardware designs that enable multi-material printing in principle, the required software is heavily underdeveloped. A typical hardware design fuses together individual materials fed into a single chamber from multiple inlets before they are deposited. This design, however, introduces a time delay between the intended material mixture and its actual deposition. In this work, inspired by diverse path planning research in robotics, we show that this mechanical challenge can be addressed via improved printer control. We propose to formulate the search for optimal multi-material printing policies in a reinforcement\r\nlearning setup. We put forward a simple numerical deposition model that takes into account the non-linear material mixing and delayed material deposition. To validate our system we focus on color fabrication, a problem known for its strict requirements for varying material mixtures at a high spatial frequency. We demonstrate that our learned control policy outperforms state-of-the-art hand-crafted algorithms.","lang":"eng"}]},{"tmp":{"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","short":"CC BY (4.0)"},"department":[{"_id":"BeBi"}],"title":"Gloss-aware color correction for 3D printing","date_updated":"2025-04-15T07:43:53Z","publication_identifier":{"isbn":["9798400701597"]},"isi":1,"_id":"12979","oa_version":"Published Version","type":"conference","publisher":"Association for Computing Machinery","publication_status":"published","keyword":["color","gloss","perception","color compensation","color management"],"project":[{"name":"Perception-Aware Appearance Fabrication","grant_number":"M03319","_id":"eb901961-77a9-11ec-83b8-f5c883a62027"}],"month":"07","file_date_updated":"2024-01-29T10:14:10Z","oa":1,"abstract":[{"lang":"eng","text":"Color and gloss are fundamental aspects of surface appearance. State-of-the-art fabrication techniques can manipulate both properties of the printed 3D objects. However, in the context of appearance reproduction, perceptual aspects of color and gloss are usually handled separately, even though previous perceptual studies suggest their interaction. Our work is motivated by previous studies demonstrating a perceived color shift due to a change in the object's gloss, i.e., two samples with the same color but different surface gloss appear as they have different colors. In this paper, we conduct new experiments which support this observation and provide insights into the magnitude and direction of the perceived color change. We use the observations as guidance to design a new method that estimates and corrects the color shift enabling the fabrication of objects with the same perceived color but different surface gloss. We formulate the problem as an optimization procedure solved using differentiable rendering. We evaluate the effectiveness of our method in perceptual experiments with 3D objects fabricated using a multi-material 3D printer and demonstrate potential applications.

To address this issue, we developed an unbiased stereology approach that uses systematic-random sampling and thin focal-plane optical sectioning of the scaffolds followed by estimation of total cell number (StereoCount). This approach was validated against an indirect method for measuring the total DNA (DNA content); and the Bürker counting chamber, the current reference method for quantifying cell number. We assessed the total cell number for cell seeding density (cells per unit volume) across four values and compared the methods in terms of accuracy, ease-of-use and time demands. The accuracy of StereoCount markedly outperformed the DNA content for cases with ~ 10,000 and ~ 125,000 cells/scaffold. For cases with ~ 250,000 and ~ 375,000 cells/scaffold both StereoCount and DNA content showed lower accuracy than the Bürker but did not differ from each other. In terms of ease-of-use, there was a strong advantage for the StereoCount due to output in terms of absolute cell numbers along with the possibility for an overview of cell distribution and future use of automation for high throughput analysis. Taking together, the StereoCount method is an efficient approach for direct cell quantification in 3D collagen scaffolds. Its major benefit is that automated StereoCount could accelerate research using 3D scaffolds focused on drug discovery for a wide variety of human diseases.","lang":"eng"}],"oa":1,"file_date_updated":"2023-05-22T07:57:37Z","related_material":{"link":[{"url":"https://doi.org/10.1038/s41598-023-37265-z","relation":"erratum"}]},"intvolume":"        13","doi":"10.1038/s41598-023-35162-z","citation":{"short":"A.

The influence of the exchange-correlation functional on the results is examined in detail. Our findings indicate that the consistent use of the HSE hybrid functional reproduces experimental results much better than the commonly used PBE functional. The HSE functional offers not only a more accurate description of the electronic band gap but also shifts the onset of molecular dissociation in the molecular dynamics simulations to significantly higher pressures. We also highlight the importance of using accurate reference standards in reflectivity experiments and reanalyze infrared and optical reflectivity data from recent experiments. Thus, our combined theoretical and experimental work explains and resolves lingering discrepancies between calculations and measurements for the investigated molecular substances under shock compression.","lang":"eng"}],"month":"04","article_type":"original","publication_status":"published","publisher":"American Physical Society","type":"journal_article","oa_version":"None","_id":"13039","isi":1,"publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"date_updated":"2023-08-01T14:45:25Z","title":"Ab initio calculation of the reflectivity of molecular fluids under shock compression","department":[{"_id":"BiCh"}]},{"month":"07","article_type":"original","type":"journal_article","publication_status":"published","publisher":"Wiley","oa_version":"Published Version","isi":1,"publication_identifier":{"eissn":["1864-564X"],"issn":["1864-5631"]},"_id":"13041","pmid":1,"tmp":{"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","short":"CC BY (4.0)"},"title":"Triarylamines as catholytes in aqueous organic redox flow batteries","department":[{"_id":"StFr"}],"date_updated":"2023-11-14T11:28:23Z","status":"public","acknowledgement":"The authors (N.L.F and R.B.J) would like to acknowledge the funding contributions of Shell and the EPRSC via I–Case studentships (grants no.

Tris(4-aminophenyl)amine was found to be the strongest candidate. Solubility and initial electrochemical performance were promising; however, polymerisation was observed during electrochemical cycling leading to rapid capacity fade prescribed to a loss of accessible active material and the limitation of ion transport processes within the cell. A mixed electrolyte system of H3PO4 and HCl was found to inhibit polymerisation producing oligomers that consumed less active material reducing rates of degradation in the redox flow battery. Under these conditions Coulombic efficiency improved by over 4 %, the maximum number of cycles more than quadrupled and an additional theoretical capacity of 20 % was accessed. This paper is, to our knowledge, the first example of triarylamines as catholytes in all-aqueous redox flow batteries and emphasises the impact supporting electrolytes can have on electrochemical performance.","lang":"eng"}],"file_date_updated":"2023-11-14T11:27:16Z","oa":1,"article_processing_charge":"Yes (in subscription journal)","article_number":"e202300128","has_accepted_license":"1"},{"publisher":"Electronic Journal of Combinatorics","type":"journal_article","publication_status":"published","oa_version":"Published Version","arxiv":1,"month":"05","article_type":"original","date_updated":"2024-10-09T21:05:26Z","title":"A note on long cycles in sparse random graphs","tmp":{"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","short":"CC BY (4.0)"},"department":[{"_id":"MaKw"}],"_id":"13042","isi":1,"publication_identifier":{"eissn":["1077-8926"]},"year":"2023","language":[{"iso":"eng"}],"publication":"Electronic Journal of Combinatorics","issue":"2","date_published":"2023-05-05T00:00:00Z","file":[{"file_size":448736,"file_name":"2023_JourCombinatorics_Anastos.pdf","success":1,"access_level":"open_access","content_type":"application/pdf","date_created":"2023-05-22T07:43:19Z","checksum":"6269ed3b3eded6536d3d9d6baad2d5b9","date_updated":"2023-05-22T07:43:19Z","relation":"main_file","creator":"dernst","file_id":"13046"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","volume":30,"author":[{"first_name":"Michael","full_name":"Anastos, Michael","id":"0b2a4358-bb35-11ec-b7b9-e3279b593dbb","last_name":"Anastos"}],"external_id":{"arxiv":["2105.13828"],"isi":["000988285500001"]},"acknowledgement":"We would like to thank the reviewers for their helpful comments and remarks.","status":"public","article_number":"P2.21","article_processing_charge":"No","has_accepted_license":"1","ddc":["510"],"abstract":[{"text":"Let Lc,n denote the size of the longest cycle in G(n, c/n),c >1 constant.

We further engineer SnTe–Cu2SnTe3 nanocomposites with a homogeneous phase distribution by decomposing the liquid SnTe precursor containing a dispersion of Cu1.5Te colloidal nanoparticles. The presence of Cu within the SnTe and the segregated semimetallic Cu2SnTe3 phase effectively improves the electrical conductivity of SnTe while simultaneously reducing the lattice thermal conductivity without compromising the Seebeck coefficient. Overall, power factors up to 3.63 mW m–1 K–2 and thermoelectric figures of merit up to 1.04 are obtained at 823 K, which represent a 167% enhancement compared with pristine SnTe.","lang":"eng"}],"oa":1,"file_date_updated":"2023-05-30T07:38:44Z","article_processing_charge":"No","has_accepted_license":"1","quality_controlled":"1","citation":{"short":"B.

Most studies have focused on spherical objects, whereas biologically relevant shapes can be highly anisotropic. In this letter, we use an experimental model system based on Giant Unilamellar Vesicles (GUVs) and dumbbell-shaped colloidal particles to mimic and investigate the first stage of the passive endocytic process: engulfment of an anisotropic object by the membrane. Our model has specific ligand–receptor interactions realized by mobile receptors on the vesicles and immobile ligands on the particles. Through a series of experiments, theory, and molecular dynamics simulations, we quantify the wrapping process of anisotropic dumbbells by GUVs and identify distinct stages of the wrapping pathway.

Peroxiredoxins (PRDXs) eliminate reactive oxygen species such as hydrogen peroxide through a catalytic cycle of Cys oxidation and reduction. Additionally, upon Cys oxidation PRDXs undergo extensive conformational rearrangements that may underlie their presently structurally poorly defined functions as molecular chaperones. Rearrangements include high molecular-weight oligomerization, the dynamics of which are, however, poorly understood, as is the impact of disulfide bond formation on these properties. Here we show that formation of disulfide bonds along the catalytic cycle induces extensive μs time scale dynamics, as monitored by magic-angle spinning NMR of the 216 kDa-large Tsa1 decameric assembly and solution-NMR of a designed dimeric mutant. We ascribe the conformational dynamics to structural frustration, resulting from conflicts between the disulfide-constrained reduction of mobility and the desire to fulfill other favorable contacts."}],"ddc":["540"],"doi":"10.1021/jacs.3c01200","intvolume":"       145","related_material":{"record":[{"relation":"research_data","status":"public","id":"12820"}]},"day":"04","corr_author":"1","scopus_import":"1","citation":{"ista":"Troussicot L, Vallet A, Molin M, Burmann BM, Schanda P. 2023.

Plasma membrane rupture was long thought to be driven by osmotic pressure, but it has recently been shown to be in many cases an active process, mediated by the protein ninjurin-18 (NINJ1). Here we resolve the structure of NINJ1 and the mechanism by which it ruptures membranes. Super-resolution microscopy reveals that NINJ1 clusters into structurally diverse assemblies in the membranes of dying cells, in particular large, filamentous assemblies with branched morphology. A cryo-electron microscopy structure of NINJ1 filaments shows a tightly packed fence-like array of transmembrane α-helices. Filament directionality and stability is defined by two amphipathic α-helices that interlink adjacent filament subunits. The NINJ1 filament features a hydrophilic side and a hydrophobic side, and molecular dynamics simulations show that it can stably cap membrane edges. The function of the resulting supramolecular arrangement was validated by site-directed mutagenesis. Our data thus suggest that, during lytic cell death, the extracellular α-helices of NINJ1 insert into the plasma membrane to polymerize NINJ1 monomers into amphipathic filaments that rupture the plasma membrane. The membrane protein NINJ1 is therefore an interactive component of the eukaryotic cell membrane that functions as an in-built breaking point in response to activation of cell death."}],"ddc":["570"],"has_accepted_license":"1","article_processing_charge":"Yes (via OA deal)","day":"29","date_created":"2023-05-28T22:01:04Z","quality_controlled":"1","citation":{"apa":"Degen, M., Santos, J.

This behaviour potentially plays a role in explaining the origin of the multipolar magnetic fields of Uranus and Neptune, whose mantles are thought to result from a mixture of H2O, NH3 and CH4 ices. Determining the stability domain, melting curve and electrical conductivity of these superionic phases is therefore crucial for modelling planetary interiors and dynamos. Here we report the melting curve of superionic ammonia up to 300 GPa from laser-driven shock compression of pre-compressed samples and atomistic calculations. We show that ammonia melts at lower temperatures than water above 100 GPa and that fluid ammonia’s electrical conductivity exceeds that of water at conditions predicted by hot, super-adiabatic models for Uranus and Neptune, and enhances the conductivity in their fluid water-rich dynamo layers."}],"article_processing_charge":"No","day":"01","scopus_import":"1","quality_controlled":"1","citation":{"mla":"Hernandez, J.
