Over the past several decades, time-series photometry of CSPNe has yielded significant results including, but not limited to, discoveries of nearly 100 binary systems, insights into pulsations and winds in young white dwarfs, and studies of stars undergoing very late thermal pulses. We have undertaken a systematic study of optical photometric variability of cataloged CSPNe, using the light curves from the Zwicky Transient Facility (ZTF). By applying appropriate variability metrics, we arrive at a list of 94 highly variable CSPN candidates. Based on the timescales of the light-curve activity, we classify the variables broadly into short- and long-timescale variables. In this first paper in this series, we focus on the former, which is the majority class comprising 83 objects. We report periods for six sources for the first time, and recover several known periodic variables. Among the aperiodic sources, most exhibit a jitter around a median flux with a stable amplitude, and a few show outbursts. We draw attention to WeSb 1, which shows a different kind of variability: prominent deep and aperiodic dips, resembling transits from a dust/debris disk. We find strong evidence for a binary nature of WeSb 1 (possibly an F-type subgiant companion). The compactness of the emission lines and inferred high electron densities make WeSb 1 a candidate for either an EGB 6-type planetary nucleus, or a symbiotic system inside an evolved planetary nebula, both of which are rare objects. To demonstrate further promise with ZTF, we report three additional newly identified periodic sources that do not appear in the list of highly variable sources. Finally, we also introduce a two-dimensional metric space defined by the von Neumann statistics and Pearson Skew and demonstrate its effectiveness in identifying unique variables of astrophysical interest, like WeSb 1.","lang":"eng"}],"related_material":{"link":[{"url":"https://doi.org/10.1088/1538-3873/adbcd8","relation":"erratum"}]},"citation":{"apa":"Bhattacharjee, S., Kulkarni, S.

Here we study how electronic structure and magnetic interactions evolve with the number of layers, 𝑛, in thin film Ruddlesden-Popper nickelates Nd𝑛+1⁢Ni𝑛⁢O3⁢𝑛+1 with 𝑛=1,3, and 5 using resonant inelastic x-ray scattering (RIXS). The RIXS spectra are consistent with a high-spin |3⁢𝑑8⁢ 𝐿̲⟩ electronic configuration, resembling that of La2−𝑥⁢Sr𝑥⁢NiO4 and the parent perovskite, NdNiO3.

However, the relationship between melt ponds and adjacent ice cliffs has not been fully explored. We investigated the seasonal drainage patterns of a melt pond on the debris-covered Zhuxi Glacier in southeast Tibet and estimated the mass loss of its adjacent ice cliff during 2023-2024. Using hourly time-lapse photogrammetry we built a series of high-resolution point clouds to quantify the evolution of the ice cliff-pond system. Our findings indicate that subaerial melting and undercutting were the primary mechanisms of ice cliff mass loss during summer. In winter when the pond water level dropped, ice cliff calving became the dominant mode of ice loss. As the water level rose in spring, calving and subaerial melting occurred simultaneously and ice loss from calving accounted for approximately 19.5 % of total ice loss from February to July 2024. Our results reveal the transitional state of this ice cliff-pond system, exhibiting characteristics of both melt hotspots and lake-terminating calving fronts, and highlight the interplay between seasonal drainage-refill pond and differing modes of ice loss on adjacent ice cliff. Future research should focus on additional high-resolution monitoring of similar systems and incorporation of ice cliff-pond dynamics in glacier-scale numerical models.

QuAK implements algorithms for solving standard decision problems, e.g., emptiness and universality, as well as constructions for safety and liveness of quantitative automata. We present the architecture of QuAK, which reflects that all of these problems reduce to either checking inclusion between two quantitative automata or computing the highest value achievable by an automaton—its so-called top value. We improve QuAK by extending these two algorithms with an option to return, alongside their results, an ultimately periodic word witnessing the algorithm’s output, as well as implementing a new safety-liveness decomposition algorithm that can handle nondeterministic automata, making QuAK more informative and capable.","lang":"eng"}],"title":"Automating the analysis of quantitative automata with QuAK","_id":"19741","author":[{"id":"87e34708-d6c6-11ec-9f5b-9391e7be2463","first_name":"Marek","last_name":"Chalupa","full_name":"Chalupa, Marek"},{"full_name":"Henzinger, Thomas A","orcid":"0000-0002-2985-7724","first_name":"Thomas A","last_name":"Henzinger","id":"40876CD8-F248-11E8-B48F-1D18A9856A87"},{"id":"b26baa86-3308-11ec-87b0-8990f34baa85","last_name":"Mazzocchi","first_name":"Nicolas Adrien","full_name":"Mazzocchi, Nicolas Adrien"},{"id":"8C6B42F8-C8E6-11E9-A03A-F2DCE5697425","first_name":"Naci E","last_name":"Sarac","full_name":"Sarac, Naci E"}],"status":"public","date_created":"2025-05-25T22:17:07Z","date_updated":"2026-07-27T12:48:18Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","related_material":{"record":[{"id":"20147","relation":"dissertation_contains","status":"public"}]},"citation":{"short":"M.

The technology to create such models is accessible to private individuals, and training and running such models can be done cheaply on consumer-grade hardware. While these advancements are a huge gain for usability and privacy, this position paper argues that the practical feasibility of impersonating specific individuals also introduces novel safety risks. For instance, this technology enables the creation of phishing emails\r\nor fraudulent social media accounts, based on small amounts of publicly available text, or by the individuals themselves to escape AI text detection. We further argue that these risks are complementary to—and distinct from—the much-discussed risks of other impersonation attacks such as image, voice, or video deepfakes, and are not adequately addressed by the larger research community, or the current generation of open- and closed-source models.","lang":"eng"}],"oa_version":"Preprint","type":"preprint","status":"public","author":[{"full_name":"Iofinova, Eugenia B","orcid":"0000-0002-7778-3221","first_name":"Eugenia B","last_name":"Iofinova","id":"f9a17499-f6e0-11ea-865d-fdf9a3f77117"},{"full_name":"Jovanovic, Andrej","last_name":"Jovanovic","first_name":"Andrej"},{"full_name":"Alistarh, Dan-Adrian","orcid":"0000-0003-3650-940X","last_name":"Alistarh","first_name":"Dan-Adrian","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87"}],"date_created":"2026-05-11T08:55:23Z","_id":"21858","title":"Position: It's time to act on the risk of efficient personalized text generation","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","date_updated":"2026-07-27T12:50:03Z","project":[{"grant_number":"101158077","name":"FastML: Efficient and Cost-Effective Distributed Machine Learning","_id":"8e35c14b-16d5-11f0-9cad-a3fc35339161"},{"_id":"9B9290DE-BA93-11EA-9121-9846C619BF3A","name":"Vienna Graduate School on Computational Optimization","grant_number":"W1260-N35"}],"citation":{"ieee":"E.

Since in some SDP instances all feasible solutions have irrational entries, numerical solvers that work with rational numbers can only find an approximate solution. We study the following question: Is it possible to certify feasibility of a given SDP using an approximate solution that is sufficiently close to some exact solution? Existing approaches make the assumption that there exist rational feasible solutions (and use techniques such as rounding and lattice reduction algorithms). We propose an alternative approach that does not need this assumption. More specifically, we show how to construct a system of polynomial equations whose set of real solutions is guaranteed to have an isolated correct solution (assuming that the target exact solution is maximum-rank). This allows, in particular, for us to use algorithms from real algebraic geometry for solving systems of polynomial equations, yielding a hybrid (or symbolic-numerical) method for SDPs. We experimentally compare it with a pure symbolic method in [D. Henrion, S. Naldi, and M. Safey El Din, SIAM J. Optim., 26 (2016), pp. 2512–2539]; the hybrid method was able to certify feasibility of many SDP instances on which the aforementioned paper failed.

How these opposing requirements are balanced within spreading tissues is not yet well understood. Here, we show that keratin intermediate filaments function in epithelial spreading by adapting tissue mechanical resilience to the stresses arising in the tissue during the spreading process. By analysing the expansion of the enveloping cell layer (EVL) over the large yolk cell in early zebrafish embryos in vivo, we found that keratin network maturation in EVL cells is promoted by stresses building up within the spreading tissue. Through genetic interference and tissue rheology experiments, complemented by a vertex model with mechanochemical feedback, we demonstrate that stress-induced keratin network maturation in the EVL increases tissue viscosity, which is essential for preventing tissue rupture. Interestingly, keratins are also required in the yolk cell for mechanosensitive actomyosin network contraction and flow, the force-generating processes pulling the EVL. These dual mechanosensitive functions of keratins enable a balance between pulling force production in the yolk cell and the mechanical resilience of the EVL against stresses generated by these pulling forces, thereby ensuring uniform and robust tissue spreading."}],"year":"2025","oa_version":"Preprint","type":"preprint","publication_status":"draft","date_created":"2025-10-14T07:25:27Z","author":[{"id":"2C0B105C-F248-11E8-B48F-1D18A9856A87","first_name":"Suyash","last_name":"Naik","orcid":"0000-0001-8421-5508","full_name":"Naik, Suyash"},{"last_name":"Keta","first_name":"Yann-Edwin","full_name":"Keta, Yann-Edwin"},{"full_name":"Pranjic-Ferscha, Kornelija","id":"4362B3C2-F248-11E8-B48F-1D18A9856A87","first_name":"Kornelija","last_name":"Pranjic-Ferscha"},{"id":"3A9DB764-F248-11E8-B48F-1D18A9856A87","last_name":"Hannezo","first_name":"Edouard B","orcid":"0000-0001-6005-1561","full_name":"Hannezo, Edouard B"},{"full_name":"Henkes, Silke","last_name":"Henkes","first_name":"Silke"},{"full_name":"Heisenberg, Carl-Philipp J","orcid":"0000-0002-0912-4566","first_name":"Carl-Philipp J","last_name":"Heisenberg","id":"39427864-F248-11E8-B48F-1D18A9856A87"}],"status":"public","tmp":{"image":"/image/cc_by_nd.png","short":"CC BY-ND (4.0)","name":"Creative Commons Attribution-NoDerivatives 4.0 International (CC BY-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nd/4.0/legalcode"},"_id":"20465","title":"Keratins coordinate tissue spreading by balancing spreading forces with tissue material properties","doi":"10.1101/2025.02.14.638262","language":[{"iso":"eng"}],"OA_place":"repository","month":"02","department":[{"_id":"CaHe"},{"_id":"EdHa"}],"corr_author":"1","oa":1,"day":"17","publication":"bioRxiv"},{"has_accepted_license":"1","file_date_updated":"2026-01-04T12:58:49Z","date_published":"2025-12-09T00:00:00Z","alternative_title":["ISTA Master's Thesis"],"article_processing_charge":"No","degree_awarded":"MS","fulldoi":"https://doi.org/10.15479/AT-ISTA-20735","ddc":["570","596","005"],"publication_status":"published","year":"2025","doi":"10.15479/AT-ISTA-20735","file":[{"file_size":566072368,"content_type":"application/zip","date_updated":"2026-01-02T13:05:07Z","file_name":"tadpoleAdEx.zip","file_id":"20919","relation":"source_file","creator":"awilson","access_level":"closed","date_created":"2026-01-01T17:26:30Z","checksum":"9e3b6b73f8cbec2c3687d17fe8e30410"},{"success":1,"date_created":"2026-01-04T12:58:49Z","checksum":"13f4c0d33923e9d5c9d56731345cf21d","access_level":"open_access","relation":"main_file","creator":"awilson","file_id":"20923","file_name":"Masters_Thesis_Alexia_Wilson_FINAL_pdfA.pdf","content_type":"application/pdf","date_updated":"2026-01-04T12:58:49Z","file_size":7170097}],"day":"09","oa":1,"corr_author":"1","doi_confirm":"1","publisher":"Institute of Science and Technology Austria","month":"12","department":[{"_id":"GradSch"},{"_id":"TiVo"},{"_id":"LoSw"}],"related_material":{"record":[{"status":"public","relation":"part_of_dissertation","id":"13097"}]},"page":"110","citation":{"chicago":"Wilson, Alexia C. “Modelling the Spinal Cord of a Tadpole: Exploring Different Ways to Model the Spinal Cord in the Xenopus Frog.” Institute of Science and Technology Austria, 2025. https://doi.org/10.15479/AT-ISTA-20735.","apa":"Wilson, A.

This thesis investigates how\r\nmodels spanning multiple levels of abstraction—from biophysically detailed Hodgkin–Huxley (HH)\r\nneurons to adaptive integrate–and–fire (I&F) formulations and synfire-chain modules—can account\r\nfor the generation of fictive swimming in the spinal cord of the Xenopus laevis tadpole. The guiding\r\nhypothesis is that a small set of neuronal mechanisms is sufficient to reproduce the essential features\r\nof rhythmic alternation, and that moving between modeling scales helps distinguish core principles\r\nfrom biological detail.\r\nA minimal bilateral HH network comprising only four canonical neuron classes—excitatory\r\ndescending interneurons (dINs), inhibitory commissural interneurons (cINs), ipsilateral inhibitory\r\ninterneurons (aINs) and motoneurons—served as a biophysical proof of concept. Tuned to reproduce\r\nexperimentally observed firing modes, the model demonstrated that rebound-prone dIN excitability,\r\ncontralateral inhibition and modest electrical coupling are sufficient to generate stable alternating\r\nactivity, even in very small networks. These results motivated the transition to simpler models\r\ncapable of efficient analysis and scaling.\r\nAdaptive exponential I&F (AdEx) neurons were calibrated to physiological recordings using\r\nsimulation-based inference, yielding tonic and phasic/rebound templates that preserved the key\r\ndynamical signatures of the HH model. Phase-plane analysis clarified the mechanisms underlying\r\nsingle-spike responses and rebound firing in dINs. At network level, the I&F models robustly\r\nreproduced left–right alternation, while highlighting constraints on synaptic kinetics and adaptation\r\nneeded to avoid multi-spike responses.\r\nFinally, a synfire-chain framework provided a complementary, timing-centric perspective, demonstrating how precise spike synchrony, synaptic delays and minimal inhibitory coupling can generate\r\nalternating left–right sequences in a feedforward setting. Together, these approaches converge on a\r\ncommon conclusion: rebound-prone ipsilateral excitation combined with precisely timed contralateral inhibition constitutes a sufficient substrate for alternating spinal rhythms.\r\nBy integrating bottom-up and top-down modeling strategies, this thesis provides a unified, extensible framework for studying spinal pattern generation. The results show that essential locomotor\r\ndynamics can be captured across multiple abstraction levels, offering both mechanistic insight and\r\npractical tools for future data-driven investigations of spinal circuit development, robustness and\r\nmodulation.","lang":"eng"}],"OA_place":"publisher","language":[{"iso":"eng"}],"publication_identifier":{"issn":["2791-4585"]}}]
