[{"abstract":[{"text":"An in-operando electro-intercalation method for the on-chip synthesis of alkali-metal-intercalated materials and their Raman spectroscopic and transport characterization in ultrahigh vacuum (UHV) is developed. We apply this method to synthesize fulleride superconductors via Rb+ intercalation into a C60 film. During the intercalation, we monitor the stoichiometry via UHV-Raman spectroscopy and probe superconductivity via transport measurements. An increase of the superconducting transition temperature from 7.0 K to 14.5 K is observed when the stoichiometry is tuned from Rb2.7C60 to Rb3C60. In our experiment, an ionic Rb+ flux into the host material is induced by an applied electronic current via a Butler–Volmer-type mechanism. Electro-intercalation captivates through improved stoichiometric precision, the ability to smoothly vary stoichiometry via duration of current application, and the absence of a lower limit of the volume of the host material. It represents a powerful concept for the on-chip synthesis of intercalated materials, battery research, and beyond.","lang":"eng"}],"file_date_updated":"2026-06-29T08:58:12Z","PlanS_conform":"1","page":"17360-17372","scopus_import":"1","license":"https://creativecommons.org/licenses/by/4.0/","external_id":{"pmid":["42260723"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"On-chip tuning of superconductivity in fullerides via current-driven Rb+ intercalation","status":"public","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"day":"23","year":"2026","acknowledgement":"A.G. and K.P.S. acknowledge the DFG through CRC 1238 (277146847, A01) and DFG project SE 2575.

Yet, electron transfer often imposes structural demands on molecular scaffolds, raising the question of whether internal mechanical constraints can directly regulate access to reactive states and, in turn, catalytic outcomes. Addressing this question has remained challenging because mechanical effects are typically inseparable from changes in composition or electronic structure. Here, we achieve this separation by exploiting two constitutionally identical molecular catalysts whose only distinction is ligand geometry. This minimal geometric variation enables or suppresses intramolecular hydrogen bonding, thereby encoding distinct mechanical constraints that isolate molecular mechanics as a variable in redox accessibility. In the α isomer, molecular constraints impose a mechanically enforced barrier that severely limits access to the reactive redox state. This disrupts the temporal ordering of elementary steps, and diverts reactivity toward competing hydrogen evolution, eroding both selectivity and stability. In contrast, mechanical compliance in the β isomer enables facile access to the redox-active state, allowing CO2 activation to intrinsically outpace water activation and yielding CO selectivities exceeding 92%. Operando spectroscopy and real-time mass spectrometry, combined with computational simulation, directly resolve this mechanically gated reaction sequence as it unfolds. Molecular mechanics thus emerge as determinants that link electron flow to reaction sequencing and catalytic selectivity, revealing that constitutionally similar catalysts can be mechanically, and therefore catalytically, distinct."}],"doi":"10.1021/jacs.6c02632","article_processing_charge":"No","publication":"Journal of the American Chemical Society","publisher":"American Chemical Society","citation":{"short":"R.M.

Whether CA3–CA3 recurrent connectivity is genetically preconfigured or environmentally shaped during ongoing memory storage is currently unknown. To address this question, we performed multicellular patch-clamp-based circuit mapping of up to eight CA3 PNs in the mouse hippocampus at multiple postnatal time points (P7–8, P18–25, and P45–50). Here, we show that the hippocampal CA3 network undergoes a developmental transformation from local, dense, and random connectivity to a distributed, sparse, and structured configuration. Thus, sparse and structured connectivity may emerge via experience-dependent mechanisms. In parallel, the strength of single synapses is downregulated; single synaptic events are sufficient to trigger postsynaptic spiking early in development, whereas spatial summation of several inputs is required at later time points. Biologically inspired models of memory storage by Hebbian synaptic plasticity and retrieval via pattern completion suggest that developmental changes improve specific aspects of memory storage and retrieval. Our results imply a developmental transformation of the neuronal code and the memory functions in the hippocampal CA3 network.</jats:p>"}],"file_date_updated":"2026-07-01T06:46:06Z","PlanS_conform":"1","_id":"22229","article_number":"5540","type":"journal_article","month":"06","quality_controlled":"1","acknowledgement":"We thank Jose Guzman, Simon Hippenmeyer, and Tim Vogels for critically reading the manuscript, Jozsef Csicsvari for useful discussions, Florian Marr for technical assistance, and Eleftheria Kralli-Beller for manuscript editing.

A hierarchical congestion approximator (HCA) consists of a laminar family of cuts in the graph and has numerous applications in approximating cut and flow problems in graphs, designing efficient routing schemes, and managing distributed networks.\r\nThere is a tradeoff between the running time for computing an HCA and its approximation quality. The best polynomial-time construction in an n-node graph gives an HCA with approximation quality O(log1.5n loglogn). Among near-linear time algorithms, the best previous result achieves approximation quality O(log4 n). We improve upon the latter result by giving the first near-linear time algorithm for computing an HCA with approximation quality O(log2 n loglogn). Additionally, our algorithm can be implemented in the parallel setting with polylogarithmic span and near-linear work, achieving the same approximation quality. This improves upon the best previous such algorithm, which has an O(log9n) approximation quality. We also present a lower bound of Ω(logn) for the approximation guarantee of hierarchical congestion approximators.\r\nCrucial for achieving a near-linear running time is a new partitioning routine that, unlike previous such routines, manages to avoid recursing on large subgraphs. To achieve the improved approximation quality, we introduce the new concept of border routability of a cut and provide an improved sparsest cut oracle for general vertex weights."}],"project":[{"_id":"bd9ca328-d553-11ed-ba76-dc4f890cfe62","call_identifier":"H2020","grant_number":"101019564","name":"The design and evaluation of modern fully dynamic data structures"},{"name":"Static and Dynamic Hierarchical Graph Decompositions","grant_number":"I05982","_id":"bda196b2-d553-11ed-ba76-8e8ee6c21103"}],"file_date_updated":"2026-07-06T06:57:16Z","page":"1417-1428","scopus_import":"1","title":"An improved quality hierarchical congestion approximator in near-linear time","external_id":{"arxiv":["2511.03716"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","arxiv":1,"status":"public","year":"2026","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"day":"09","OA_place":"publisher","acknowledgement":"We thank Evangelos Kosinas for helpful discussions on this topic.\r\nFunded by the European Union.

At the core of our new method is an analytical reduction of the surface integral that defines the winding number, resulting in a single ray-mesh intersection test and an elementary sum over boundary edges per evaluation. This construction is orders of magnitude more efficient than the state of the art in practice, which we show in an extensive performance benchmark. Conveniently, the method also reduces to the best-available asymptotic complexity in the worst case, and it introduces no approximations apart from floating-point errors. Our algorithm is conceptually simple to understand, straightforward to implement and debug, and it works reliably even on extremely noisy and corrupt input geometry."}],"file_date_updated":"2026-07-06T06:13:12Z","PlanS_conform":"1","status":"public","day":"03","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"year":"2026","scopus_import":"1","title":"Fast and exact winding numbers for triangle meshes","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","quality_controlled":"1","acknowledgement":"We thank Sadashige Ishida and Ryusuke Sugimoto for their insightful discussions and proofreading and other members of the ISTA\r\nVisual Computing Group for their general feedback.

However, it remains unclear how environmental variation shapes adaptation, what is learned, and when memory of past conditions is retained. Here we show how cyclic environmental change can produce robust memory. Using a model athermal disordered solid trained by inverse design to attain target elastic properties over a prescribed range, we find that the system evolves toward a marginally absorbing manifold (MAM), meaning that training is reversible within the training range but not beyond it, which encodes a memory of that range. We further propose a general mechanism for MAM formation and memory encoding based on discontinuities in the gradient of the trained quantity. These results provide a simple, broadly applicable physical framework for how adaptive systems learn under changing environments and retain memory of past conditions.","lang":"eng"}],"month":"06","issue":"2","type":"journal_article","article_number":"023029","_id":"22248","date_updated":"2026-07-06T07:28:45Z","volume":4,"OA_place":"publisher","acknowledgement":"We thank Nathan Keim, Aayush Desai, Nicholas Barton,\r\nand Gašper Tkacik for important and stimulating discussions. ˇ\r\nThe work was funded by the Institute of Science and Technology Austria.","quality_controlled":"1","date_created":"2026-07-05T22:01:37Z","supplementarymaterial":"no","language":[{"iso":"eng"}],"author":[{"full_name":"Zu, Mengjie","id":"26dd9e7c-e86a-11eb-a854-82ac731c9ae2","last_name":"Zu","first_name":"Mengjie"},{"first_name":"Carl Peter","orcid":"0000-0002-1307-5074","last_name":"Goodrich","id":"EB352CD2-F68A-11E9-89C5-A432E6697425","full_name":"Goodrich, Carl Peter"}],"article_processing_charge":"Yes","doi":"10.1103/48k2-cw3b","publication":"PRX Life","has_accepted_license":"1","intvolume":"         4","article_type":"original","publication_status":"published","das_tickbox":"1","ddc":["570"],"date_published":"2026-06-18T00:00:00Z","publisher":"American Physical Society","citation":{"ama":"Zu M, Goodrich CP.

Deciding whether an input hypergraph admits LO k-colouring with a fixed number of colours is NP-complete (and in the special case of graphs, LO colouring coincides with the usual graph colouring).\r\nHere, we investigate the complexity of approximating the “linearly ordered chromatic number” of a hypergraph. We prove that the following promise problem is NP-complete: Given a 3-uniform hypergraph, distinguish between the case that it is LO 3-colourable, and the case that it is not even LO 4-colourable. We prove this result by a combination of algebraic, topological, and combinatorial methods, building on and extending a topological approach for studying approximate graph colouring introduced by Krokhin, Opršal, Wrochna, and Živný (2023).","lang":"eng"}],"issue":"2","month":"05","type":"journal_article","article_number":"10","_id":"22247","date_updated":"2026-07-06T09:06:29Z","volume":18,"acknowledgement":"This research was supported by the Charles University project PRIMUS/21/SCI/014, by the Ministry of Education, Youth\r\nand Sports of the Czech Republic under the project MSCAfellow5_MUNI (CZ.02.01.01/00/22_010/0003229), and by the\r\nAustrian Science Fund (FWF project P31312-N35).

Furthermore, the distance sketches themselves are planar graphs. First, we show that every unweighted string graph G has an O(1)-distortion planar emulator: that is, there exists an edge-weighted planar graph H containing every vertex in G, such that every pair of vertices (u,v) satisfies δG(u,v) ≤ δH(u,v) ≤ O(1) · δG(u,v). Furthermore, we show that for any constant ε > 0, there is an edge-weighted planar graph H′ such that every pair of vertices (u,v) satisfies δG(u,v) ≤ δH′(u,v) ≤ (1+ε) · δG(u,v) + O(ε−4polylogn). No previous constructions of sparse distance sketches were known even for intersection graphs of simple shapes like axis-parallel rectangles or fat convex polygons.\r\nAs applications, we construct the first (1+ε, +O(1)) mixed-distortion tree cover and distance oracle for arbitrary string graphs, as well as the first additive +(εΔ+O(1))-distortion embedding of string graphs G with diameter Δ into graphs of constant treewidth O(ε−4)."}],"tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"day":"09","year":"2026","status":"public","external_id":{"arxiv":["2510.21700"]},"title":"Cutting planarians: Planar emulators for string graphs","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","arxiv":1,"scopus_import":"1"},{"publication_status":"published","article_processing_charge":"No","doi":"10.15479/AT-ISTA-21423","acknowledged_ssus":[{"_id":"ScienComp"}],"has_accepted_license":"1","author":[{"first_name":"Zuzana","last_name":"Dunajova","id":"4B39F286-F248-11E8-B48F-1D18A9856A87","full_name":"Dunajova, Zuzana"}],"language":[{"iso":"eng"}],"related_material":{"record":[{"status":"public","id":"13314","relation":"part_of_dissertation"},{"status":"public","relation":"research_data","id":"13116"},{"relation":"research_data","id":"21439","status":"public"},{"status":"public","id":"21427","relation":"part_of_dissertation"}]},"date_created":"2026-03-11T08:30:49Z","publication_identifier":{"issn":["2663-337X"],"isbn":["978-3-99078-076-3"]},"department":[{"_id":"GradSch"},{"_id":"EdHa"}],"file":[{"relation":"main_file","content_type":"application/pdf","file_id":"21446","checksum":"47ce6a48a0c63f28eca6e64c9ffd2c84","date_created":"2026-03-12T20:38:52Z","creator":"zdunajov","file_name":"2026_Dunajova_Zuzana_Thesis_pdfA.pdf","access_level":"closed","file_size":14662770,"date_updated":"2026-03-12T20:38:52Z","embargo":"2026-09-11","embargo_to":"open_access"},{"access_level":"closed","file_size":32961408,"date_updated":"2026-03-13T11:19:21Z","file_name":"Thesis-Dunajova_source_file.docx","relation":"source_file","content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document","file_id":"21447","creator":"zdunajov","checksum":"5dec5afdffd47c2b0b162d0fe1bed925","date_created":"2026-03-12T20:40:18Z"}],"oa_version":"Published Version","corr_author":"1","publisher":"Institute of Science and Technology Austria","citation":{"ieee":"Z.

The concern is that initial deforestation could critically impair the forest’s water recycling capacities, further harming the remaining forest through reduced annual precipitation. Many studies have focused on annual mean precipitation changes, due to its widespread perception as a central control on the Amazon rain forest’s stability. However, the impact of deforestation goes beyond changes in the annual mean precipitation. Yet, global coarse-resolution climate models are not well suited to investigate changes in short-duration and localized events due to their coarse resolution. Here, we circumvent these issues by analyzing a full-deforestation scenario simulated by a global storm-resolving model. We focus on changes in the tail of the hourly distribution of precipitation, temperature, and wind. Hourly precipitation becomes more extreme in the absence of the forest than in an intact forest, with an increased occurrence of both no rain and intense rainfall. These changes are driven by enhanced moisture convergence that strengthens vertical velocity. On average, the near-surface temperature rises significantly by about 3.84 °C, and the daily minimum temperature after deforestation becomes similar to the daily maximum temperature before deforestation. Except for wet-bulb temperature, human heat stress indicators shift to more severe levels, with implications for health and a significant reduction in work productivity. Finally, the mean 10 m wind speed intensifies by a factor of four, with the 99th percentile wind speed doubling. To summarize, our findings, while based on an idealized case, provide a stark warning of the effects of continuing deforestation of the Amazon."}],"_id":"21233","issue":"1","month":"02","type":"journal_article","quality_controlled":"1","date_updated":"2026-07-06T12:55:02Z","volume":17,"acknowledgement":"AY acknowledges funding by the CLICCS centre of excellence subproject A3 funded by DFG.

AM Canum Venaticorum (AM CVn) stars are ultra-compact binary systems composed of a white dwarf primary accreting from a hydrogen-deficient donor. They play a crucial role in astrophysics as potential progenitors of Type Ia supernovae and as laboratories for gravitational wave studies. However, their formation and evolutionary history remain incomplete. Three formation channels have been discussed in the literature: the white dwarf, He-star, and cataclysmic variable channels.\r\n\r\nAims. The chemical composition of the accretor atmosphere reflects the material transferred from the donor. In this work we took the first accurate measurements of the fundamental parameters of the accreting white dwarf in ZTF J225237.05−051917.4, including the abundances of key elements such as carbon, nitrogen, and silicon, by analysing ultraviolet spectra obtained with the Hubble Space Telescope (HST). These measurements provide new insight into the evolutionary history of the system and, together with existing optical observations, establish it as a benchmark to develop our pipeline, paving the way for its application to a larger sample of AM CVn systems.\r\n\r\nMethods. We determined the binary parameters through photometric analysis and constrained the atmospheric parameters of the white dwarf accretor, including its effective temperature, surface gravity, and chemical abundances, by fitting the HST ultraviolet spectrum with synthetic spectral models. We then inferred the system’s formation channel by comparing the results with theoretical evolutionary models.\r\n\r\nResults. According to our measurements, the accretor’s effective temperature (Teff) is 23 300 ± 600 K and the surface gravity (log g) is 8.4 ± 0.3, which imply an accretor mass (MWD) of 0.86 ± 0.16 M⊙. We find a high nitrogen-to-carbon abundance ratio by mass of > 153.\r\n\r\nConclusions. The accretor is significantly hotter than previous estimates based on simplified blackbody fits to the spectral energy distribution, underscoring the importance of detailed spectral modelling for accurately determining system parameters. Our results show that ultraviolet spectroscopy is well suited to constraining the formation channels of AM CVn systems. Of the three proposed formation channels, the He-star channel can be excluded given the high nitrogen-to-carbon ratio. Our results are consistent with both the white dwarf and cataclysmic variable channels.","lang":"eng"}],"year":"2026","day":"01","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"status":"public","arxiv":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","external_id":{"arxiv":["2512.04147"]},"title":"The evolutionary history of ultra-compact accreting binaries: I.

Perhaps the most surprising features of this population are the presence of Balmer absorption and ubiquitous strong Balmer breaks. Recent models link these features to an active supermassive black hole (SMBH) cocooned in very dense gas (NH ∼ 1024 cm−2). We present a stringent test of such models using VLT/MUSE observations of A2744-45924, the most luminous LRD known to date (LHα ≈ 1044 erg s−1), located behind the Abell-2744 lensing cluster at z = 4.464 (μ = 1.8). We detect a moderately extended Lyα nebula (h ≈ 5.7 pkpc), spatially offset from the point-like Hα seen by JWST by ≈1.6 pkpc. The Lyα emission is narrow (FWHM = 270 ± 15 km s−1), and faint (Lyα = 0.07Hα) compared to Lyα nebulae typically observed around quasars of similar luminosity. We detect compact N IV]λ1486 emission, spatially aligned with Hα, and a spatial shift in the far-UV continuum matching the Lyα offset. We discuss that Hα and Lyα have distinct physical origins: Hα originates from the AGN, while Lyα is powered by star formation. In the environment of A2744-45924, we identified four extended Lyα halos (Δz < 0.02, Δr < 100 pkpc). Their Lyα luminosities match the expectations based on Hα emission, and show no evidence for radiation from A2744-45924 affecting its surroundings. The lack of strong, compact, and broad Lyα and the absence of a luminous extended halo, suggest that the UV AGN light is obscured by dense gas cloaking the SMBH with a covering factor close to unity."}],"project":[{"name":"Young galaxies as tracers and agents of cosmic reionization","grant_number":"101076224","_id":"bd9b2118-d553-11ed-ba76-db24564edfea"}],"file_date_updated":"2026-02-16T07:35:03Z","PlanS_conform":"1","scopus_import":"1","external_id":{"arxiv":["2505.09542"]},"arxiv":1,"title":"A weak Ly α halo for an extremely bright little red dot.
