However, systems that require verification or monitoring by a third party to ensure compliance with a specification might contain sensitive information, causing privacy concerns when usual runtime verification approaches are used. Privacy is compromised if protected information about the system, or sensitive data that is processed by the system, is revealed. In addition, revealing the specification being monitored may undermine the essence of third-party verification.\r\n\r\nIn this thesis, we propose a protocol for privacy-preserving runtime verification of systems against formal sequential specifications. We develop the protocol in two steps. In the first step, the monitor verifies whether the system satisfies the specification without learning anything else, though both parties are aware of the specification. In the second step, we extend the protocol to ensure that the system remains oblivious to the monitored specification, while the monitor learns only whether the system satisfies the specification and nothing more. Our protocol adapts and improves existing techniques used in cryptography, and more specifically, multi-party computation.\r\n\r\nThe sequential specification defines the observation step of the monitor, whose granularity depends on the situation (e.g., banks may be monitored on a daily basis). Our protocol exchanges a single message per observation step, after an initialization phase. This design minimizes communication overhead, enabling relatively lightweight privacy-preserving monitoring. We implement our approach for monitoring specifications described by register automata and evaluate it experimentally.\r\n","lang":"eng"}],"degree_awarded":"MS","year":"2026","page":"60","corr_author":"1","supervisor":[{"last_name":"Henzinger","full_name":"Henzinger, Thomas A","first_name":"Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2985-7724"}],"project":[{"grant_number":"101020093","call_identifier":"H2020","name":"Vigilant Algorithmic Monitoring of Software","_id":"62781420-2b32-11ec-9570-8d9b63373d4d"},{"name":"Security and Privacy by Design for Complex Systems","_id":"34a4ce89-11ca-11ed-8bc3-8cc37fb6e11f","grant_number":"F8512"}],"status":"public","oa_version":"Published Version","type":"dissertation","citation":{"ista":"Karimi M. 2026.

While the former is starting to be well understood, the latter remains a major theoretical challenge, especially in programmable systems and the so-called semi-addressable regime, where binding is often nondeterministic and the formation of off-target structures negatively influences the assembly. Here, we show that it is possible to simultaneously sculpt the assembly outcome and the assembly kinetics through the underexplored design space of binding energies and particle concentrations. By formulating the assembly process as a complex reaction network, we calculate and optimize the tradeoff between assembly speed and quality and show that parameter optimization can speed up assembly by many orders of magnitude without lowering the yield of the target structure. Although the exact speedup varies from design to design, we find the largest speedups for nondeterministic systems where unoptimized assembly is the slowest, sometimes even making them assemble faster than optimized, fully addressable designs. Therefore, these results not only solve a key challenge in semi-addressable self-assembly but further emphasize the utility of semi-addressability, where designs have the potential to be faster as well as cheaper (fewer particle species) and better (higher yield). More broadly, our results highlight the importance of parameter optimization in programmable self-assembly and provide practical tools for simultaneous optimization of kinetics and yield in a wide range of systems.","lang":"eng"}],"publisher":"AIP Publishing","arxiv":1,"file":[{"checksum":"9bdb8870930e83edb973408da3038559","content_type":"application/pdf","file_id":"21415","relation":"main_file","access_level":"open_access","success":1,"creator":"dernst","file_name":"2026_JourChemPhysics_Huebl.pdf","file_size":6903766,"date_updated":"2026-03-09T10:38:55Z","date_created":"2026-03-09T10:38:55Z"}],"oa":1,"quality_controlled":"1","external_id":{"arxiv":["2510.07876"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2026-02-28T00:00:00Z","scopus_import":"1","ddc":["540"],"article_processing_charge":"Yes (via OA deal)","file_date_updated":"2026-03-09T10:38:55Z","date_created":"2026-03-08T23:01:45Z","_id":"21408","publication_status":"published","language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1089-7690"],"issn":["0021-9606"]},"day":"28","department":[{"_id":"CaGo"},{"_id":"GradSch"}],"has_accepted_license":"1","article_number":"084904","month":"02","article_type":"original","publication":"Journal of Chemical Physics","date_updated":"2026-03-09T10:40:41Z","doi":"10.1063/5.0304731","acknowledgement":"The research was supported by the Gesellschaft für Forschungsförderung Niederösterreich under Project No. FTI23-G-011.","OA_place":"publisher","author":[{"id":"5eb8629e-15b2-11ec-abd3-e6f3e5e01f32","first_name":"Maximilian","full_name":"Hübl, Maximilian","last_name":"Hübl"},{"orcid":"0000-0002-1307-5074","id":"EB352CD2-F68A-11E9-89C5-A432E6697425","full_name":"Goodrich, Carl Peter","first_name":"Carl Peter","last_name":"Goodrich"}],"OA_type":"hybrid","volume":164,"citation":{"ista":"Hübl M, Goodrich CP. 2026.

For decades, biologists have considered meiotic drivers as interesting, albeit esoteric, case studies. It is now clear, however, that meiotic drive is more common and phylogenetically widespread than previously supposed. Indeed, intensive study of a few well-known cases has begun to reveal the evolutionary genomic consequences of meiotic drive. We argue here that many features of genome evolution, content, and organization that are seemingly inexplicable by organismal adaptation or nearly neutral processes are instead best accounted for by recurrent histories of meiotic drive. We review how meiotic drive can affect the evolution of sequences, gene copy numbers, genes with functions in meiosis and gametogenesis, signatures of “selection,” chromosome rearrangements, and karyotype evolution. We also explore the interactions of meiotic drive elements with other classes of selfish genetic elements, including satellite DNAs, transposable elements, and with the endogenous host genes involved in drive suppression. Finally, we argue that some aspects of drive-mediated genome evolution are now sufficiently well established that we might reverse the direction of discovery—rather than ask how drive affects genome evolution, we can use genome data to discover new putative drive elements.","lang":"eng"}],"status":"public","DOAJ_listed":"1","intvolume":"        43","PlanS_conform":"1","title":"The evolutionary genomics of meiotic drive","citation":{"chicago":"Presgraves, Daven C., R.

These re-routing mechanisms rely on pre-installed static re-routing rules at the nodes (the routers), which depend only on local failure information, namely on the failed links incident to the node. Ideally, a network is perfectly resilient: the re-routing rules ensure that packets are always successfully routed to their destinations as long as the source and the destination are still physically connected in the underlying network after the failures. Unfortunately, there are examples where achieving perfect resilience is not possible. Surprisingly, only very little is known about the algorithmic aspect of when and how perfect resilience can be achieved. We investigate the computational complexity of analyzing such local fast re-routing mechanisms. Our main result is a negative one: we show that even checking whether a given set of static re-routing rules ensures perfect resilience is coNP-complete. Additionally, we investigate other fundamental variations of the problem. In particular, we show that our coNP-completeness proof also applies to scenarios where the re-routing rules have specific patterns (known as skipping in the literature). On the positive side, for scenarios where nodes do not have information about the link from which a packet arrived (the so-called in-port), we present a linear-time algorithm to realize perfect resilience whenever possible (which we show can also be determined in linear time).

However, switching AFM domains is challenging, as magnetic fields do not couple to the bulk antiferromagnetic order parameter. Here we show that magnetic-field-driven switching of AFM domains can in many cases be enabled by a generic reduction of magnetic exchange at surfaces. We use statistical mechanics and Monte Carlo simulations to demonstrate that an inequivalence in magnetic exchange between top and bottom surface moments, combined with the enhanced magnetic susceptibility of surface spins, can enable deterministic selection of antiferromagnetic domains depending on the magnetic-field ramping direction. We further show that this mechanism provides a natural interpretation for experimental observations of hysteresis in magneto-optical response of the van der Waals AFM $\\mathrm{MnBi_2Te_4}$. Our findings highlight the critical role of surface spins in responses of antiferromagnets to magnetic fields.

Here, we explore the possibility of speeding up these interactions in 3D crystals via parametric amplification. For this purpose, we derive a general Hamiltonian for the parametric amplification of spin-motion coupling that is broadly applicable to normal modes with motion transverse to or along the spatial extent of the crystal. Unlike in lower-dimensional crystals, we find that the ability to faithfully (uniformly) amplify the spin-spin interactions in 3D crystals depends on the physical implementation of the spin-motion coupling. We consider the light-shift gate, and the so-called phase-insensitive and phase-sensitive Mølmer-Sørensen (MS) gates, and we find that only the phase-sensitive MS gate can be faithfully amplified in general 3D crystals. We discuss a situation where nonuniform amplification can be advantageous. We also reconsider the effect of counter-rotating terms on parametric amplification and find that they are not as detrimental as previous studies suggest.","lang":"eng"}],"year":"2026","intvolume":"        25","PlanS_conform":"1","corr_author":"1","status":"public","project":[{"_id":"bdb108fd-d553-11ed-ba76-83dc74a9864f","name":"QUANTUM INFORMATION SYSTEMS BEYOND CLASSICAL CAPABILITIES / P5- Integration of Superconducting Quantum Circuits","grant_number":"F07105"}],"file_date_updated":"2026-03-16T09:24:53Z","article_processing_charge":"Yes (via OA deal)","date_created":"2026-03-15T23:01:35Z","scopus_import":"1","date_published":"2026-03-01T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","ddc":["530"],"quality_controlled":"1","oa":1,"external_id":{"arxiv":["2507.16741"]},"arxiv":1,"publisher":"American Physical Society","file":[{"access_level":"open_access","relation":"main_file","success":1,"checksum":"f0dc6a50222b778fd75cc72a28d38689","file_id":"21456","content_type":"application/pdf","file_size":1421954,"date_updated":"2026-03-16T09:24:53Z","date_created":"2026-03-16T09:24:53Z","file_name":"2026_PhysicalReviewApplied_Hawaldar.pdf","creator":"dernst"}],"date_updated":"2026-04-14T09:04:08Z","publication":"Physical Review Applied","article_type":"original","month":"03","article_number":"034004","has_accepted_license":"1","publication_identifier":{"eissn":["2331-7019"]},"department":[{"_id":"JoFi"},{"_id":"GradSch"}],"day":"01","publication_status":"published","_id":"21449","language":[{"iso":"eng"}],"type":"journal_article","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"},"oa_version":"Published Version","title":"Parametric amplification of spin-motion coupling in three-dimensional trapped-ion crystals","citation":{"apa":"Hawaldar, S., Nikhil, N., Rey, A.

Therefore, evolutionary models predict that massive stars in lower-Z environments are able to retain more of their hydrogen-rich layers and evolve into brighter cool supergiants (cool SGs; Teff < 7 kK). Surprisingly, in galaxies in the metallicity range 0.2 ≲ Z/Z⊙ ≲ 1.5, previous studies have not found a metallicity dependence on the upper luminosity limit Lmax of cool SGs. Here, we add four galaxies to the sample studied for this purpose with data from the Hubble Space Telescope and the James Webb Space Telescope (JWST). Observations of the extremely metal-poor dwarf galaxy I Zw 18 from JWST allow us to extend the studied metallicity range down to Z/Z⊙ ≈ 1/40. For cool SGs in all studied galaxies, including I Zw 18, we find a constant value of Lmax ≈ 105.6 L⊙, similar to literature results for 0.2 ≲ Z/Z⊙ ≲ 1.5. In I Zw 18 and the other studied galaxies, the presence of Wolf-Rayet stars has been previously inferred. Although we cannot rule out that some of them become intermediate-temperature objects, this paints a picture in which evolved stars with L > 105.6 L⊙ burn helium as hot, helium-rich stars down to extremely low metallicity. We argue that metallicity-independent late-phase mass loss would be the most likely mechanism responsible for this. Regardless of the exact stripping mechanism (winds or, for example, binary interaction), for the Early Universe our results imply a limitation on black hole masses and a contribution of stars born with M ≳ 30 M⊙ to its surprisingly strong nitrogen enrichment. We propose a scenario in which single stars at low metallicity emit sufficiently hard ionizing radiation to produce He II and C IV lines. In this scenario, late-phase metallicity-independent mass loss produces hot, helium-rich stars. Due to the well-understood metallicity dependence on the radiation-driven winds of hot stars, a window of opportunity would open below 0.2 Z⊙, where self-stripped helium-rich stars can exist without dense Wolf-Rayet winds that absorb hard ionizing radiation."}],"status":"public","DOAJ_listed":"1","intvolume":"       707","PlanS_conform":"1","title":"A constant upper luminosity limit of cool supergiant stars down to the extremely low metallicity of I Zw 18","citation":{"short":"A.

A cocoon of dense excited gas is emerging as a key component to explain the most striking properties of LRDs, such as strong Balmer breaks and Balmer absorption, as well as the weak IR emission. To dissect the structure of LRDs, we analyzed new deep JWST/NIRSpec PRISM and G395H spectra of FRESCO-GN-9771, one of the most luminous known LRDs at z = 5.5. These spectra reveal a strong Balmer break, broad Balmer lines, and very narrow [O III] emission. We revealed a forest of optical [Fe II] lines, which we argue are emerging from a dense (nH = 109 − 10 cm−3) warm layer with electron temperature Te ≈ 7000 K. The broad wings of Hα and Hβ have an exponential profile due to electron scattering in this same layer. The high Hα : Hβ : Hγ flux ratio of ≈10.4 : 1 : 0.14 is an indicator of collisional excitation and resonant scattering dominating the Balmer line emission. A narrow Hγ component, unseen in the other two Balmer lines due to outshining by the broad components, could trace the ISM of a normal host galaxy with a star formation rate of ∼5 M⊙ yr−1. The warm layer is mostly opaque to Balmer transitions, producing a characteristic P Cygni profile in the line centers suggesting outflowing motions. This same layer is responsible for shaping the Balmer break. The broadband spectrum can be reasonably matched by a simple photoionized slab model that dominates the λ > 1500 Å continuum and a low-mass (∼108 M⊙) galaxy that could explain the narrow [O III], with only a subdominant contribution to the UV continuum. Our findings indicate that Balmer lines are not directly tracing the gas kinematics near the SMBH and that the BH mass scale is likely much lower than virial indicators suggest.","lang":"eng"}],"project":[{"name":"Young galaxies as tracers and agents of cosmic reionization","_id":"bd9b2118-d553-11ed-ba76-db24564edfea","grant_number":"101076224"}],"DOAJ_listed":"1","status":"public","PlanS_conform":"1","corr_author":"1","intvolume":"       707","volume":707,"citation":{"ama":"Torralba Torregrosa A, Matthee JJ, Pezzulli G, et al.

With JWST, the SFMS can now be investigated at high redshifts down to masses of ∼106 M⊙, using sensitive star formation rate tracers such as the Hα emission, which allow us to probe the variability in the star formation histories. We present inferences of the SFMS based on 316 Hα-selected galaxies at z ∼ 4 − 5 with log(M★/M⊙) = 6.4 − 10.6. These galaxies were identified behind the Abell 2744 lensing cluster with NIRCam grism spectroscopy from the survey All the Little Things (ALT). At face value, our data suggest a shallow slope in the SFMS (SFR ∝ M★α, with α = 0.45). After we corrected this for the Hα-flux limited nature of our survey using a Bayesian framework, the slope steepened to α = 0.59+0.10−0.09, whereas current data on their own are inconclusive on the mass dependence of the scatter. These slopes differ significantly from the slope of ∼1 that is expected from the observed evolution of the galaxy stellar mass function and from simulations. When we fixed the slope to α = 1, we found evidence for a decreasing intrinsic scatter with stellar mass (from ∼0.5 dex at M★ = 108 M⊙ to 0.4 dex at M★ = 1010 M⊙). This difference might be explained by a (combination of) luminosity-dependent SFR(Hα) calibration, a population of (mini)-quenched low-mass galaxies, or underestimated dust attenuation in high-mass galaxies. Future deep observations with different facilities can quantify these processes, which will enable us to achieve better insights into the variability of the star formation histories.","lang":"eng"}],"DOAJ_listed":"1","project":[{"grant_number":"101076224","_id":"bd9b2118-d553-11ed-ba76-db24564edfea","name":"Young galaxies as tracers and agents of cosmic reionization"}],"status":"public","corr_author":"1","PlanS_conform":"1","intvolume":"       707","ddc":["520"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2026-03-01T00:00:00Z","scopus_import":"1","date_created":"2026-03-15T23:01:36Z","file_date_updated":"2026-03-16T10:48:07Z","article_processing_charge":"No","file":[{"checksum":"c056b00ce7324849754521fde10fb7ca","file_id":"21459","content_type":"application/pdf","relation":"main_file","access_level":"open_access","success":1,"creator":"dernst","file_name":"2026_AstronomyAstrophysics_DiCesare.pdf","file_size":1821411,"date_created":"2026-03-16T10:48:07Z","date_updated":"2026-03-16T10:48:07Z"}],"publisher":"EDP Sciences","arxiv":1,"external_id":{"arxiv":["2510.19044"]},"quality_controlled":"1","oa":1},{"publication_identifier":{"eissn":["1947-5713"],"issn":["1947-5705"]},"department":[{"_id":"FrPe"}],"day":"04","publication_status":"published","_id":"21454","language":[{"iso":"eng"}],"article_number":"2639085","has_accepted_license":"1","article_type":"original","month":"03","date_updated":"2026-03-16T10:21:38Z","publication":"Geomatics Natural Hazards and Risk","acknowledgement":"The work is partially financed by USDMA and WIHG, Dehradun.

Here, we study nonlinear THz-induced Kerr effect in a generic material LaAlO3. After detailed analysis of temporal oscillations of the Kerr signal, we identify an 𝐸𝑔 Raman mode at 1.1 THz excited through a two-photon process, while two additional peaks (0.86 and 0.36 THz) arise from phase matching of the near-infrared probe beam with co- and counterpropagating THz pump fields, mediated by off-resonant electronic hyperpolarizability. These results demonstrate the crucial role of kinematic effects in shaping THz-induced Kerr response and establish a framework for interpreting nonlinear spectroscopies in complex materials.","lang":"eng"}],"issue":"10"},{"author":[{"full_name":"Bahl, Monika","first_name":"Monika","last_name":"Bahl"},{"last_name":"Koutentakis","full_name":"Koutentakis, Georgios","first_name":"Georgios","id":"d7b23d3a-9e21-11ec-b482-f76739596b95"},{"orcid":"0000-0003-4074-2570","last_name":"Maslov","full_name":"Maslov, Mikhail","first_name":"Mikhail","id":"2E65BB0E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Tom","full_name":"Jungnickel, Tom","last_name":"Jungnickel"},{"first_name":"Timo","full_name":"Gaßen, Timo","last_name":"Gaßen"},{"full_name":"Lemeshko, Mikhail","first_name":"Mikhail","last_name":"Lemeshko","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6990-7802"},{"last_name":"Heckl","first_name":"Oliver H.","full_name":"Heckl, Oliver H."}],"OA_type":"hybrid","OA_place":"publisher","doi":"10.1088/2515-7647/ae3506","acknowledgement":"This research was funded in whole or in part by the Austrian Science Fund (FWF) [10.55776/F1004].

In optical fields, where multiple vortices coexist, the local nature of vortex OAM and the absence of a common rotation axis make the total OAM of the field difficult to quantify. Here, we introduce the R index—a metric that captures the intrinsic OAM content of any structured optical field, from pure Laguerre–Gaussian modes to arbitrary multi vortex superpositions. Not only does this metric quantify the total OAM, it also assesses field purity, providing insight into the fidelity and robustness of the OAM generation. By unifying OAM characterization into a single figure of merit, the R index enables direct comparison across diverse beam profiles and facilitates the identification of optimal configurations for both foundational studies and applied technologies."}],"year":"2026"},{"author":[{"id":"a19ed178-1337-11ed-9389-c30ab879a82a","full_name":"Backlund, Sofia Maria","first_name":"Sofia Maria","last_name":"Backlund"},{"id":"43161670-5719-11EA-8025-FABC3DDC885E","last_name":"Stankowski","full_name":"Stankowski, Sean","first_name":"Sean"},{"first_name":"Rosina Matilde","full_name":"Soler Schaller, Rosina Matilde","last_name":"Soler Schaller","id":"9e668447-8c32-11ed-b0c7-8dc2d7b80803"}],"OA_type":"hybrid","OA_place":"publisher","doi":"10.1002/ajb2.70175","acknowledgement":"We thank the Barton group at the Institute of Scienceand Technology Austria for many fruitful conversationsthat triggered the germination of the ideas and questions discussed here.

Whereas animal studies have offered cellular- and synaptic-level accounts of these effects, human neuroimaging studies show that exercise improves hippocampal-cortical connectivity at the macroscale level. However, the neurophysiological basis of exercise-induced effects on hippocampal-cortical circuits remains unknown. Experimental evidence supports the idea that hippocampal sharp wave-ripples (SWR) play a critical role in learning and memory. Coupling between SWRs in the hippocampus and neocortex may reflect modulations in inter-regional connectivity required by mnemonic processes. Here, we examine the hypothesis that exercise modulates hippocampal-cortical ripple dynamics in the human brain. We performed intracranial recordings in epilepsy patients undergoing pre-surgical evaluation, during awake resting state, before and after an exercise session. Exercise increased ripple rate in the hippocampus. Exercise also enhanced the coupling and phase-synchrony between cortical ripples in the limbic and the default mode (DM) cortical networks and hippocampal SWRs. Further, a higher heart rate during exercise, reflecting exercise intensity, was related to a subsequent increase in resting state ripples across specific cortical networks, including the DM network. These results offer the first direct evidence that a single exercise session elicits changes in ripple events, a well-established neurophysiological marker of mnemonic processing. The characterisation and anatomical distribution of the described modulation points to hippocampal ripples as a potential mechanism by which exercise elicits its reported short-term effects in cognition.","lang":"eng"}],"issue":"2","year":"2026","oa":1,"quality_controlled":"1","publisher":"Oxford University Press","file":[{"success":1,"relation":"main_file","access_level":"open_access","file_id":"21478","content_type":"application/pdf","checksum":"b5b45c16defeaf88056fc3b939bd0350","date_updated":"2026-03-23T14:27:39Z","date_created":"2026-03-23T14:27:39Z","file_size":33974419,"creator":"dernst","file_name":"2026_BrainCommunications_Cardenas.pdf"}],"article_processing_charge":"Yes","file_date_updated":"2026-03-23T14:27:39Z","date_created":"2026-03-22T23:04:34Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","scopus_import":"1","date_published":"2026-03-09T00:00:00Z","ddc":["570"]},{"acknowledgement":"We acknowledge insightful discussions with Antoine Browaeys, Mari Carmen Bañuls, Soonwon Choi, Thierry Lahaye, Daniel Stilck-França, Georgios Styliaris, and Xavier Waintal.

Under the same conditions, we also provide an efficient scheme to estimate fidelities between the learned and the experimental states.

With the advent of JWST, we are now able to routinely observe Hα in galaxies at high redshift (z ≳ 3) and thus measure their star formation rates (SFRs). However, using classical SFR(Hα) calibrations to derive the SFRs leads to biased results because high-redshift galaxies are commonly characterized by low metallicities and bursty star formation histories, affecting the conversion factor between the Hα luminosity (LHα) and the SFR. We developed a set of new SFR(Hα) calibrations that allowed us to predict the SFRs of Hα-emitters at z ≳ 3 with very little error. We used the SPHINX cosmological simulations to select a sample of star-forming galaxies representative of the Hα-emitter population observed with JWST. We then derived linear corrections to the classical SFR(Hα) calibrations that took variations in the physical properties (e.g., stellar metallicities) among individual galaxies into account. We obtained two new SFR(Hα) calibrations that compared to the classical calibrations reduce the root mean squared error (RMSE) in the predicted SFRs by ΔRMSE ≈ 0.04 dex and ΔRMSE ≈ 0.06 dex, respectively. Using the recent JWST NIRCam/grism observations of Hα-emitters at z ∼ 6, we show that the new calibrations affect the high-redshift galaxy population statistics: (i) the estimated cosmic SFR density decreases by ΔρSFR ≈ 12%, and (ii) the observed slope of the star formation main sequence increases by Δ∂logSFR/∂logM★ = 0.08 ± 0.02."}],"project":[{"grant_number":"101076224","name":"Young galaxies as tracers and agents of cosmic reionization","_id":"bd9b2118-d553-11ed-ba76-db24564edfea"}],"DOAJ_listed":"1","status":"public","PlanS_conform":"1","corr_author":"1","intvolume":"       707","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2026-03-05T00:00:00Z","ddc":["520"],"article_processing_charge":"No","file_date_updated":"2026-03-23T15:44:09Z","date_created":"2026-03-23T14:58:03Z","arxiv":1,"publisher":"EDP Sciences","file":[{"success":1,"access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_id":"21492","checksum":"7429076b381dd498084f40ffd199e714","date_created":"2026-03-23T15:44:09Z","date_updated":"2026-03-23T15:44:09Z","file_size":904565,"creator":"dernst","file_name":"2026_AstronomyAstrophysics_Kramarenko.pdf"}],"oa":1,"quality_controlled":"1","external_id":{"arxiv":["2509.05403"]}},{"status":"public","project":[{"grant_number":"FTI23-G-011","name":"Dynamically reconfigurable self-assembly with triangular DNA-origami bricks","_id":"8dd93da8-16d5-11f0-9cad-d2c70200d9a5"}],"DOAJ_listed":"1","intvolume":"         8","corr_author":"1","year":"2026","abstract":[{"lang":"eng","text":"Controlling the size and shape of assembled structures is a fundamental challenge in self-assembly and is highly relevant in material design and biology. Here, we show that specific but promiscuous short-range binding interactions make it possible to economically assemble linear filaments of user-defined length. Our approach leads to independent control over the mean and width of the filament size distribution and allows us to smoothly explore design trade-offs between assembly quality (spread in size) and cost (number of particle species). We employ a simple hierarchical assembly protocol to minimize assembly times and show that multiple stages of hierarchy make it possible to extend our approach to the assembly of higher-dimensional structures. Our work provides a conceptually simple solution to size control that is applicable to a broad range of systems, from DNA nanoparticles to supramolecular polymers and beyond."}],"oa":1,"quality_controlled":"1","file":[{"file_size":2680924,"date_updated":"2026-03-23T15:53:29Z","date_created":"2026-03-23T15:53:29Z","file_name":"2026_PhysicalReviewResearch_Huebl.pdf","creator":"dernst","relation":"main_file","access_level":"open_access","success":1,"checksum":"6d8a68e4a19f8dad5abdf75f72316f3d","file_id":"21493","content_type":"application/pdf"}],"publisher":"American Physical Society","ddc":["530"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2026-03-05T00:00:00Z","date_created":"2026-03-23T14:58:31Z","article_processing_charge":"Yes","file_date_updated":"2026-03-23T15:53:29Z","department":[{"_id":"CaGo"},{"_id":"GradSch"}],"day":"05","publication_identifier":{"eissn":["2643-1564"]},"language":[{"iso":"eng"}],"_id":"21482","publication_status":"published","article_number":"L012054","has_accepted_license":"1","article_type":"original","month":"03","date_updated":"2026-03-23T15:59:11Z","publication":"Physical Review Research","acknowledgement":"We thank Maitane Muñoz-Basagoiti for helpful discussions.

Of the many ways in which they influence natural phenomena, perhaps the most consequential is their capacity to transfer electrical charge during contact4,5,6,7,8,9,10—which occurs even between samples of the same oxide—yet the symmetry-breaking parameter that causes this remains unidentified11,12. Here we show that adventitious carbonaceous molecules adsorbed from the environment are the symmetry-breaking factor in same-material oxide contact electrification (CE). We use acoustic levitation to measure charge exchange between a sphere and a plate composed of identical amorphous silicon dioxide (SiO2). Although charging polarity is random for co-prepared samples, we control it with baking or plasma treatment. Observing the charge-exchange relaxation afterwards, we see dynamics over a timescale of hours and connect this directly to the presence of adventitious carbon with time-of-flight mass spectrometry, low-energy ion scattering and infrared spectroscopy. Going further, we confirm that adventitious carbon can even determine charge exchange among different oxides. Our results identify the symmetry-breaking parameter that causes insulating oxides to exchange charge in settings ranging from desert sands4 to volcanic plumes5,6, while simultaneously highlighting an overlooked factor in CE more broadly."}],"publisher":"Springer Nature","file":[{"success":1,"access_level":"open_access","relation":"main_file","file_id":"21494","content_type":"application/pdf","checksum":"dafef9ed575b44be4263e948a47ae056","date_created":"2026-03-24T06:57:08Z","date_updated":"2026-03-24T06:57:08Z","file_size":12245694,"file_name":"2026_Nature_Grosjean.pdf","creator":"dernst"}],"quality_controlled":"1","oa":1,"external_id":{"pmid":["41851325"]},"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","date_published":"2026-03-18T00:00:00Z","ec_funded":1,"pmid":1,"ddc":["540"],"article_processing_charge":"Yes (via OA deal)","file_date_updated":"2026-03-24T06:57:08Z","date_created":"2026-03-23T15:04:00Z"}]
