[{"title":"Influence of copper telluride nanodomains on the transport properties of n-type bismuth telluride","ec_funded":1,"abstract":[{"lang":"eng","text":"The high processing cost, poor mechanical properties and moderate performance of Bi2Te3–based alloys used in thermoelectric devices limit the cost-effectiveness of this energy conversion technology. Towards solving these current challenges, in the present work, we detail a low temperature solution-based approach to produce Bi2Te3-Cu2-xTe nanocomposites with improved thermoelectric performance. Our approach consists in combining proper ratios of colloidal nanoparticles and to consolidate the resulting mixture into nanocomposites using a hot press. The transport properties of the nanocomposites are characterized and compared with those of pure Bi2Te3 nanomaterials obtained following the same procedure. In contrast with most previous works, the presence of Cu2-xTe nanodomains does not result in a significant reduction of the lattice thermal conductivity of the reference Bi2Te3 nanomaterial, which is already very low. However, the introduction of Cu2-xTe yields a nearly threefold increase of the power factor associated to a simultaneous increase of the Seebeck coefficient and electrical conductivity at temperatures above 400 K. Taking into account the band alignment of the two materials, we rationalize this increase by considering that Cu2-xTe nanostructures, with a relatively low electron affinity, are able to inject electrons into Bi2Te3, enhancing in this way its electrical conductivity. The simultaneous increase of the Seebeck coefficient is related to the energy filtering of charge carriers at energy barriers within Bi2Te3 domains associated with the accumulation of electrons in regions nearby a Cu2-xTe/Bi2Te3 heterojunction. Overall, with the incorporation of a proper amount of Cu2-xTe nanoparticles, we demonstrate a 250% improvement of the thermoelectric figure of merit of Bi2Te3."}],"publication":"Chemical Engineering Journal","status":"public","publication_status":"published","day":"15","date_updated":"2025-04-14T07:43:52Z","oa_version":"Submitted Version","article_processing_charge":"No","date_published":"2021-08-15T00:00:00Z","publisher":"Elsevier","volume":418,"oa":1,"intvolume":"       418","publication_identifier":{"issn":["1385-8947"]},"quality_controlled":"1","month":"08","external_id":{"isi":["000655672000005"]},"type":"journal_article","citation":{"apa":"Zhang, Y., Xing, C., Liu, Y., Li, M., Xiao, K., Guardia, P., … Cabot, A.

In the present work, we investigate the effect of different dopants to enhance the Cu2−xS performance and also its thermal stability. Among the tested options, Pb-doped Cu2−xS shows the highest improvement in stability against sulfur volatilization. Additionally, Pb incorporation allows tuning charge carrier concentration, which enables a significant improvement of the power factor.

To understand how actin regulatory proteins work together to generate actin-rich structures such as filopodia, we analyzed the localization of diverse actin regulators within filopodia in Drosophila embryos and in a complementary in vitro system of filopodia-like structures (FLSs). We found that the composition of the regulatory protein complex where actin is incorporated (the filopodial tip complex) is remarkably heterogeneous both in vivo and in vitro. Our data reveal that different pairs of proteins correlate with each other and with actin bundle length, suggesting the presence of functional subcomplexes. This is consistent with a theoretical framework where three or more redundant subcomplexes join the tip complex stochastically, with any two being sufficient to drive filopodia formation. We provide an explanation for the observed heterogeneity and suggest that a mechanism based on multiple components allows stereotypical filopodial dynamics to arise from diverse upstream signaling pathways.","lang":"eng"}],"publication":"Journal of Cell Biology","status":"public","publication_status":"published","article_processing_charge":"No","date_published":"2021-03-19T00:00:00Z","day":"19","date_updated":"2026-04-02T13:59:43Z","oa_version":"Published Version","intvolume":"       220","publication_identifier":{"eissn":["1540-8140"]},"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"},"publisher":"Rockefeller University Press","oa":1,"volume":220,"month":"03","external_id":{"pmid":["33740033"],"isi":["000663160600002"]},"type":"journal_article","quality_controlled":"1","file":[{"content_type":"application/pdf","date_created":"2021-04-06T10:39:08Z","creator":"dernst","file_id":"9310","checksum":"4739ffd90f2c7e05ac5b00f057c58aa2","file_name":"2021_JCB_Dobramysl.pdf","date_updated":"2021-04-06T10:39:08Z","access_level":"open_access","file_size":9019720,"success":1,"relation":"main_file"}],"pmid":1,"citation":{"ama":"Dobramysl U, Jarsch IK, Inoue Y, et al.

One of our contributions is that the convergence analysis and rate of convergence results are obtained using conditions which appear not complicated and restrictive as assumed in other previous related results in the literature. We then show that Fermat–Weber location problem and primal–dual three-operator splitting are special cases of fixed point problem of nonexpansive mapping and consequently obtain the convergence analysis of inertial iteration methods for Fermat–Weber location problem and primal–dual three-operator splitting in real Hilbert spaces. Some numerical implementations are drawn from primal–dual three-operator splitting to support the theoretical analysis."}],"status":"public","publication_status":"published","publication":"Results in Mathematics","article_processing_charge":"No","date_published":"2021-03-25T00:00:00Z","day":"25","date_updated":"2024-10-09T21:00:33Z","oa_version":"None"},{"acknowledgement":"We thank Carl Goodrich and the members of the Heisenberg and Hannezo groups, in particular Reka Korei, for help, technical advice, and discussions; and the Bioimaging and zebrafish facilities of the IST Austria for continuous support.

Here, we show that rigidity percolation provides a simple and robust theoretical framework to predict material/structural PTs of embryonic tissues from local cell connectivity. By using percolation theory, combined with directly monitoring dynamic changes in tissue rheology and cell contact mechanics, we demonstrate that the zebrafish blastoderm undergoes a genuine rigidity PT, brought about by a small reduction in adhesion-dependent cell connectivity below a critical value. We quantitatively predict and experimentally verify hallmarks of PTs, including power-law exponents and associated discontinuities of macroscopic observables. Finally, we show that this uniform PT depends on blastoderm cells undergoing meta-synchronous divisions causing random and, consequently, uniform changes in cell connectivity. Collectively, our theoretical and experimental findings reveal the structural basis of material PTs in an organismal context.","lang":"eng"}]},{"title":"The multi-cover persistence of Euclidean balls","ddc":["516"],"abstract":[{"lang":"eng","text":"Given a locally finite X⊆Rd and a radius r≥0, the k-fold cover of X and r consists of all points in Rd that have k or more points of X within distance r.

While standard methods suffice for the filtration in scale, we need novel geometric and topological concepts for the filtration in depth.

However, detecting excitatory postsynaptic potentials (EPSPs) or currents (EPSCs) in behaving animals remains challenging, because of unfavorable signal-to-noise ratio, high frequency, fluctuating amplitude, and variable time course of synaptic events.\r\nNew method: We developed a method for synaptic event detection, termed MOD (Machine-learning Optimal-filtering Detection-procedure), which combines concepts of supervised machine learning and optimal Wiener filtering. Experts were asked to manually score short epochs of data. The algorithm was trained to obtain the optimal filter coefficients of a Wiener filter and the optimal detection threshold. Scored and unscored data were then processed with the optimal filter, and events were detected as peaks above threshold.\r\nResults: We challenged MOD with EPSP traces in vivo in mice during spatial navigation and EPSC traces in vitro in slices under conditions of enhanced transmitter release. The area under the curve (AUC) of the receiver operating characteristics (ROC) curve was, on average, 0.894 for in vivo and 0.969 for in vitro data sets, indicating high detection accuracy and efficiency.\r\nComparison with existing methods: When benchmarked using a (1 − AUC)−1 metric, MOD outperformed previous methods (template-fit, deconvolution, and Bayesian methods) by an average factor of 3.13 for in vivo data sets, but showed comparable (template-fit, deconvolution) or higher (Bayesian) computational efficacy.\r\nConclusions: MOD may become an important new tool for large-scale, real-time analysis of synaptic activity."}],"ec_funded":1,"ddc":["570"],"title":"MOD: A novel machine-learning optimal-filtering method for accurate and efficient detection of subthreshold synaptic events in vivo","article_processing_charge":"Yes (via OA deal)","date_published":"2021-03-09T00:00:00Z","date_updated":"2025-06-12T06:39:15Z","day":"09","oa_version":"Published Version","acknowledged_ssus":[{"_id":"SSU"}],"status":"public","publication_status":"published","publication":"Journal of Neuroscience Methods","department":[{"_id":"PeJo"},{"_id":"ScienComp"}],"date_created":"2021-04-18T22:01:39Z","author":[{"first_name":"Xiaomin","last_name":"Zhang","id":"423EC9C2-F248-11E8-B48F-1D18A9856A87","full_name":"Zhang, Xiaomin"},{"full_name":"Schlögl, Alois","id":"45BF87EE-F248-11E8-B48F-1D18A9856A87","last_name":"Schlögl","orcid":"0000-0002-5621-8100","first_name":"Alois"},{"first_name":"David H","orcid":"0000-0001-7577-1676","id":"3AE48E0A-F248-11E8-B48F-1D18A9856A87","last_name":"Vandael","full_name":"Vandael, David H"},{"orcid":"0000-0001-5001-4804","first_name":"Peter M","full_name":"Jonas, Peter M","last_name":"Jonas","id":"353C1B58-F248-11E8-B48F-1D18A9856A87"}],"has_accepted_license":"1","doi":"10.1016/j.jneumeth.2021.109125","_id":"9329","scopus_import":"1","acknowledgement":"This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement number 692692 to P.J.) and the Fond zur Förderung der Wissenschaftlichen Forschung (Z 312-B27, Wittgenstein award to P.J.).

Here we show that α2δ subunits are essential for the formation and organization of glutamatergic synapses. Using a cellular α2δ subunit triple-knockout/knockdown model, we demonstrate a failure in presynaptic differentiation evidenced by defective presynaptic calcium channel clustering and calcium influx, smaller presynaptic active zones, and a strongly reduced accumulation of presynaptic vesicle-associated proteins (synapsin and vGLUT). The presynaptic defect is associated with the downscaling of postsynaptic AMPA receptors and the postsynaptic density. The role of α2δ isoforms as synaptic organizers is highly redundant, as each individual α2δ isoform can rescue presynaptic calcium channel trafficking and expression of synaptic proteins. Moreover, α2δ-2 and α2δ-3 with mutated metal ion-dependent adhesion sites can fully rescue presynaptic synapsin expression but only partially calcium channel trafficking, suggesting that the regulatory role of α2δ subunits is independent from its role as a calcium channel subunit. Our findings influence the current view on excitatory synapse formation. First, our study suggests that postsynaptic differentiation is secondary to presynaptic differentiation. Second, the dependence of presynaptic differentiation on α2δ implicates α2δ subunits as potential nucleation points for the organization of synapses. Finally, our results suggest that α2δ subunits act as transsynaptic organizers of glutamatergic synapses, thereby aligning the synaptic active zone with the postsynaptic density."}],"title":"Presynaptic α2δ subunits are key organizers of glutamatergic synapses","ddc":["570"],"oa_version":"Published Version","acknowledged_ssus":[{"_id":"EM-Fac"}],"day":"06","date_updated":"2025-06-12T06:56:21Z","date_published":"2021-04-06T00:00:00Z","article_processing_charge":"No","status":"public","publication_status":"published","publication":"Proceedings of the National Academy of Sciences of the United States of America","quality_controlled":"1","external_id":{"pmid":["33782113"],"isi":["000637398300002"]},"type":"journal_article","month":"04","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"},"oa":1,"volume":118,"publisher":"National Academy of Sciences","publication_identifier":{"eissn":["1091-6490"]},"intvolume":"       118","article_type":"original","project":[{"name":"In situ analysis of single channel subunit composition in neurons: physiological implication in synaptic plasticity and behaviour","_id":"25CA28EA-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"694539"}],"citation":{"ama":"Schöpf CL, Ablinger C, Geisler SM, et al.

LRs are issued from non-dividing cells entering consecutive steps of formative divisions, proliferation and elongation. The chromatin remodeling protein PICKLE (PKL) negatively regulates auxin-mediated LR formation through a mechanism that is not yet known. Here we show that PKL interacts with RETINOBLASTOMA-RELATED 1 (RBR1) to repress the LATERAL ORGAN BOUNDARIES-DOMAIN 16 (LBD16) promoter activity. Since LBD16 function is required for the formative division of LR founder cells, repression mediated by the PKL–RBR1 complex negatively regulates formative division and LR formation. Inhibition of LR formation by PKL–RBR1 is counteracted by auxin, indicating that, in addition to auxin-mediated transcriptional responses, the fine-tuned process of LR formation is also controlled at the chromatin level in an auxin-signaling dependent manner."}],"scopus_import":"1","issue":"8","acknowledgement":"This research was supported by a postdoctoral fellowship of the Carl Tryggers Foundation (to K.Ö.) and by grants from Vetenskapsrådet (Nr.: 621-2004-2921 to L.B.) and VINNOVA (to L.B. and S.R.).\r\nWe thank Frederic Berger, Hidehiro Fukaki, Malcolm Bennett, Claudia Köhler, Jiri Friml for providing pRBR1::RBR1-RFP, ssl2-1, slr-1, pPKL::PKL-GFP seeds and the DR5 expressing vector, respectively.

In the present note we prove that a similar approximation holds for t=O(α2) if one includes a nontrivial effective dynamics for the phonons that is generated by an operator proportional to α−2 and quadratic in creation and annihilation operators. Our result implies that the electron ground state remains close to its initial state for times of order α2, while the phonon fluctuations around the coherent state ξα can be described by a time-dependent Bogoliubov transformation.","lang":"eng"}],"status":"public","publication_status":"published","publication":"Letters in Mathematical Physics","date_published":"2021-04-05T00:00:00Z","article_processing_charge":"No","oa_version":"Published Version","day":"05","date_updated":"2026-04-02T13:58:00Z","publication_identifier":{"issn":["0377-9017"],"eissn":["1573-0530"]},"intvolume":"       111","publisher":"Springer Nature","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":111,"oa":1,"external_id":{"isi":["000637359300002"]},"month":"04","type":"journal_article","quality_controlled":"1","citation":{"apa":"Mitrouskas, D.

However, these polaritons present a crucial limitation: their directional propagation is intrinsically determined by the crystal structure of the host material, imposing forbidden directions of propagation. Here, we demonstrate that directional polaritons (in-plane hyperbolic phonon polaritons) in a vdW crystal (α-phase molybdenum trioxide) can be directed along forbidden directions by inducing an optical topological transition, which emerges when the slab is placed on a substrate with a given negative permittivity (4H–silicon carbide). By visualizing the transition in real space, we observe exotic polaritonic states between mutually orthogonal hyperbolic regimes, which unveil the topological origin of the transition: a gap opening in the dispersion. This work provides insights into optical topological transitions in vdW crystals, which introduce a route to direct light at the nanoscale.","lang":"eng"}],"file":[{"file_name":"2021_ScienceAdv_Duan.pdf","checksum":"4b383d4a1d484a71bbc64ecf401bbdbb","file_id":"9343","creator":"dernst","date_created":"2021-04-19T11:17:29Z","content_type":"application/pdf","relation":"main_file","success":1,"date_updated":"2021-04-19T11:17:29Z","file_size":717489,"access_level":"open_access"}],"citation":{"ama":"Duan J, Álvarez-Pérez G, Voronin KV, et al.

We show that this phenomenon is captured by particular Lagrangian discretizations of the porous medium and the thin film equations, and we obtain sufficient criteria for the occurrence of waiting times that are consistent with the known ones for the original PDEs. For the spatially discrete solution, the waiting time phenomenon refers to a deviation of the edge of support from its original position by a quantity comparable to the mesh width, over a mesh-independent time interval. Our proof is based on estimates on the fluid velocity in Lagrangian coordinates. Combining weighted entropy estimates with an iteration technique à la Stampacchia leads to upper bounds on free boundary propagation. Numerical simulations show that the phenomenon is already clearly visible for relatively coarse discretizations.","lang":"eng"}],"title":"The waiting time phenomenon in spatially discretized porous medium and thin film equations","day":"01","date_updated":"2023-08-08T13:10:40Z","oa_version":"Preprint","article_processing_charge":"No","date_published":"2021-01-01T00:00:00Z","status":"public","publication_status":"published","publication":"SIAM Journal on Numerical Analysis","author":[{"orcid":"0000-0002-0479-558X","first_name":"Julian L","full_name":"Fischer, Julian L","last_name":"Fischer","id":"2C12A0B0-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Daniel","full_name":"Matthes, Daniel","last_name":"Matthes"}],"date_created":"2021-04-18T22:01:42Z","department":[{"_id":"JuFi"}],"_id":"9335","doi":"10.1137/19M1300017","acknowledgement":"This research was supported by the DFG Collaborative Research Center TRR 109, “Discretization in Geometry and Dynamics”.","issue":"1","scopus_import":"1","main_file_link":[{"url":"https://arxiv.org/abs/1911.04185","open_access":"1"}],"language":[{"iso":"eng"}],"isi":1,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","year":"2021"},{"oa_version":"Preprint","day":"07","date_updated":"2023-08-08T13:15:11Z","date_published":"2021-04-07T00:00:00Z","article_processing_charge":"No","publication_status":"published","status":"public","publication":"Journal of Functional Analysis","abstract":[{"lang":"eng","text":"We consider the stochastic quantization of a quartic double-well energy functional in the semiclassical regime and derive optimal asymptotics for the exponentially small splitting of the ground state energy.

Although it has been intensively studied by both biologists and physicists, a commonly accepted definition of cell-cell adhesion is still being debated. Cell-cell adhesion has been described at the molecular scale as a function of adhesion receptors controlling binding affinity, at the cellular scale as resistance to detachment forces or modulation of surface tension, and at the tissue scale as a regulator of cellular rearrangements and morphogenesis. In this review, we aim to summarize and discuss recent advances in the molecular, cellular, and theoretical description of cell-cell adhesion, ranging from biomimetic models to the complexity of cells and tissues in an organismal context. In particular, we will focus on cadherin-mediated cell-cell adhesion and the role of adhesion signaling and mechanosensation therein, two processes central for understanding the biological and physical basis of cell-cell adhesion.","lang":"eng"}],"ddc":["570"],"title":"Holding it together: when cadherin meets cadherin"},{"author":[{"first_name":"Kay","last_name":"Kirkpatrick","full_name":"Kirkpatrick, Kay"},{"first_name":"Simone Anna Elvira","orcid":"0000-0001-5059-4466","last_name":"Rademacher","id":"856966FE-A408-11E9-977E-802DE6697425","full_name":"Rademacher, Simone Anna Elvira"},{"first_name":"Benjamin","last_name":"Schlein","full_name":"Schlein, Benjamin"}],"department":[{"_id":"RoSe"}],"date_created":"2021-04-25T22:01:30Z","_id":"9351","has_accepted_license":"1","doi":"10.1007/s00023-021-01044-1","acknowledgement":"The authors gratefully acknowledge Gérard Ben Arous for suggesting this kind of result.
