At subparsec separations, SMBHBs can be identified as quasars with periodic variability, with previous periodicity searches uncovering significant candidates. However, these searches focused primarily on sinusoidal signals, while theoretical models and hydrodynamical simulations predict that binaries produce more complex non-sinusoidal pulse shapes. Here we examine the efficacy of the Lomb–Scargle periodogram (LSP; one of the most popular tools for periodicity searches in unevenly sampled lightcurves) to detect periodicities with a sawtooth shape mimicking results of hydrodynamical simulations. We simulate idealized well-sampled lightcurves, lightcurves that mimic the data in the Palomar Transient Factory (PTF) analyzed in M. Charisi et al. (2016), and lightcurves that resemble our expectations for single-band data in the upcoming Legacy Survey of Space and Time (LSST) of the Rubin Observatory. We approximate quasar variability with a damped random walk (DRW) model, inject sinusoidal and sawtooth pulse shapes, and assess their statistical significance. We find that in the presence of red noise, the LSP detects a relatively low fraction of the sinusoidal signals (∼45%, ∼24%, and ∼23%, in the PTF-like, idealized, and LSST-like lightcurves, respectively). The fraction is significantly reduced for sawtooth periodicity (with only ∼9% in PTF-like and ∼1% in idealized and LSST-like lightcurves). These low recovery rates imply that previous searches have missed the large majority of binaries. They also have significant implications for the detection of SMBHBs in upcoming LSST necessitating the development of advanced tools that go beyond the simple LSP."}],"day":"01","date_created":"2026-04-12T22:01:49Z","file_date_updated":"2026-05-04T10:24:49Z","volume":997,"title":"Lomb-scargle periodogram struggles with non-sinusoidal supermassive Black Hole binary signatures in quasar lightcurves","DOAJ_listed":"1","language":[{"iso":"eng"}]},{"OA_type":"gold","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"oa_version":"Published Version","file":[{"date_created":"2026-05-04T09:49:53Z","file_name":"2026_AstrophysicalJourLetters_Bartos.pdf","relation":"main_file","file_id":"21788","file_size":866725,"access_level":"open_access","content_type":"application/pdf","checksum":"ac46ba3d13f0150ccbc42665bed3ae47","creator":"dernst","success":1,"date_updated":"2026-05-04T09:49:53Z"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_identifier":{"eissn":["2041-8213"],"issn":["2041-8205"]},"OA_place":"publisher","corr_author":"1","has_accepted_license":"1","issue":"2","year":"2026","status":"public","publisher":"IOP Publishing","publication_status":"published","date_updated":"2026-05-04T09:54:18Z","article_type":"original","date_published":"2026-01-10T00:00:00Z","month":"01","department":[{"_id":"ZoHa"}],"article_number":"L44","article_processing_charge":"Yes","oa":1,"intvolume":" 996","arxiv":1,"external_id":{"arxiv":["2508.08558"]},"ddc":["520"],"acknowledgement":"The authors thank Davide Gerosa and Matthew Mould for valuable suggestions.

The component spins are both exceptionally high (a1 = 0.90 +0.10/-0.19, a2 = 0.80 +0.20/-0.51), which is difficult to explain with repeated mergers. Here we show that the black hole spin vectors are closely aligned with each other while significantly tilted relative to the binary’s orbital angular momentum, pointing to a common accretion-driven origin. We examine astrophysical formation channels capable of producing near-equal, high-mass, and mutually aligned spins consistent with GW231123—particularly binaries embedded in AGN disks and Population III remnants, which grew via coherent misaligned gas accretion. We further argue that other high-mass, high-spin events, e.g., GW190521, may share a similar evolutionary pathway. These findings underscore the critical role of sustained, coherent accretion in shaping the most extreme black hole binaries."}],"volume":996,"file_date_updated":"2026-05-04T09:49:53Z","language":[{"iso":"eng"}],"title":"Accretion is all you need: Black Hole spin alignment in merger GW231123 indicates accretion pathway","DOAJ_listed":"1"},{"language":[{"iso":"eng"}],"DOAJ_listed":"1","title":"Formation of Be stars via wind accretion: Case study on Black Hole + Be star binaries","volume":996,"file_date_updated":"2026-04-16T06:24:30Z","date_created":"2026-04-12T22:01:50Z","day":"10","abstract":[{"lang":"eng","text":"Be stars are rapidly rotating main-sequence stars that play a crucial role in understanding stellar evolution and binary interactions.

Our analysis is based on numerical simulations of the WRLOF process in massive binaries, building on recent theoretical work. We demonstrate that the WRLOF model can efficiently form BHBe binaries under reasonable assumptions on stellar wind velocities. Using rapid binary population synthesis, we estimate the population of such systems in the Milky Way, predicting ∼1800−3200 currently existing BHBe binaries originating from the WRLOF channel. These systems are characterized by high eccentricities and exceptionally wide orbits, with typical orbital periods exceeding 1000 days and a peak distribution around ∼10,000 days. Due to their long orbital separations, these BHBe binaries are promising targets for future detection via astrometric and interferometric observations."}],"scopus_import":"1","quality_controlled":"1","author":[{"first_name":"Zhenwei","full_name":"Li, Zhenwei","last_name":"Li"},{"last_name":"Jia","first_name":"Shi","full_name":"Jia, Shi"},{"full_name":"Wei, Dandan","first_name":"Dandan","id":"5dd129bd-0601-11ef-b325-833284687b76","last_name":"Wei"},{"last_name":"Ge","first_name":"Hongwei","full_name":"Ge, Hongwei"},{"first_name":"Hailiang","full_name":"Chen, Hailiang","last_name":"Chen"},{"last_name":"Zhang","first_name":"Yangyang","full_name":"Zhang, Yangyang"},{"first_name":"Xuefei","full_name":"Chen, Xuefei","last_name":"Chen"},{"full_name":"Han, Zhanwen","first_name":"Zhanwen","last_name":"Han"}],"_id":"21714","doi":"10.3847/2041-8213/ae3008","type":"journal_article","publication":"The Astrophysical Journal Letters","external_id":{"arxiv":["2512.18565"]},"ddc":["520"],"citation":{"ieee":"Z.

Leveraging X-ray through far-infrared observations of two of the most luminous known little red dots, we directly measure their bolometric luminosities. We find evidence that more than half of the bolometric luminosity likely emerges in the rest-frame optical, with Lbol/L5100 = 5, roughly half the value for “standard” active galactic nuclei. Meanwhile, the X-ray emitting corona, UV-emitting blackbody, and reprocessed mid to far-infrared emission are all considerably subdominant, assuming that the far-infrared luminosity is well below current measured limits. We present new bolometric corrections that dramatically lower inferred bolometric luminosities by a factor of 10 compared to published values in the literature. These bolometric corrections are in accord with expectations from models in which gas absorption and reprocessing are responsible for the red rest-frame optical colors of little red dots. We discuss how this lowered luminosity scale suggests a lower mass scale for the population by at least an order of magnitude (e.g., ∼105–107 M⊙ black holes, and ∼108 M⊙ galaxies), alleviating tensions with clustering, overmassive black holes, and the integrated black hole mass density in the Universe.","lang":"eng"}],"language":[{"iso":"eng"}],"title":"What you see is what you get: Empirically measured bolometric luminosities of Little Red Dots","DOAJ_listed":"1","volume":996,"file_date_updated":"2026-05-04T11:19:48Z","oa_version":"Published Version","file":[{"date_updated":"2026-05-04T11:19:48Z","access_level":"open_access","content_type":"application/pdf","file_size":684400,"checksum":"7b3cb025d4bcaa35c6e52bd0c8fb6cf4","creator":"dernst","success":1,"file_id":"21792","date_created":"2026-05-04T11:19:48Z","file_name":"2026_AstrophysicalJour_Greene.pdf","relation":"main_file"}],"OA_type":"gold","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"OA_place":"publisher","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","has_accepted_license":"1","issue":"2","status":"public","year":"2026","publisher":"IOP Publishing","date_updated":"2026-05-04T11:20:42Z","publication_status":"published","month":"01","article_type":"original","date_published":"2026-01-10T00:00:00Z","PlanS_conform":"1","article_processing_charge":"Yes","article_number":"129","department":[{"_id":"JoMa"}],"oa":1},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_identifier":{"eissn":["1879-0356"],"issn":["1369-5266"]},"OA_place":"publisher","OA_type":"hybrid","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"oa_version":"Published Version","issue":"6","status":"public","year":"2026","has_accepted_license":"1","corr_author":"1","PlanS_conform":"1","publication_status":"epub_ahead","date_updated":"2026-05-04T11:15:57Z","date_published":"2026-04-01T00:00:00Z","article_type":"original","month":"04","publisher":"Elsevier","oa":1,"department":[{"_id":"XiFe"}],"article_number":"102881","article_processing_charge":"Yes (via OA deal)","publication":"Current Opinion in Plant Biology","type":"journal_article","intvolume":" 91","ddc":["580"],"acknowledgement":"This work was supported by JSPS KAKENHI (grant number JP22J01430) and the Osamu Hayaishi Memorial Scholarship for Study Abroad for H.N.","citation":{"ieee":"H.

Indeed, recent global warming has decreased major crop yields, emphasizing the urgent need to elucidate the molecular and cellular mechanisms underlying heat-induced male sterility. This review synthesizes current knowledge on how heat stress disrupts microsporogenesis and microgametogenesis, and how plants counteract these stresses through diverse thermotolerance mechanisms. We emphasize temperature-sensitive processes, including meiotic progression in male germ cells, programmed cell death of somatic tapetal nurse cells, and post-meiotic pollen tube development. We further discuss how epigenetic regulators enhance thermotolerance by reprogramming DNA methylation landscapes and modulating histone variant distribution. Finally, we propose future directions aimed at understanding the mechanisms of reproductive thermotolerance from the epigenetic perspective.","lang":"eng"}]},{"volume":40,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2505.04539"}],"language":[{"iso":"eng"}],"title":"Qualitative analysis of ω-regular objectives on robust MDPs","date_created":"2026-04-12T22:01:50Z","day":"14","abstract":[{"lang":"eng","text":"Robust Markov Decision Processes (RMDPs) generalize classical MDPs that consider uncertainties in transition probabilities by defining a set of possible transition functions. An objective is a set of runs (or infinite trajectories) of the RMDP, and the value for an objective is the maximal probability that the agent can guarantee against the adversarial environment. We consider (a) reachability objectives, where given a target set of states, the goal is to eventually arrive at one of them; and (b) parity objectives, which are a canonical representation for ω-regular objectives. The qualitative analysis problem asks whether the objective can be ensured with probability 1. In this work, we study the qualitative problem for reachability and parity objectives on RMDPs without making any assumption over the structures of the RMDPs, e.g., unichain or aperiodic. Our contributions are twofold. We first present efficient algorithms with oracle access to uncertainty sets that solve qualitative problems of reachability and parity objectives. We then report experimental results demonstrating the effectiveness of our oracle-based approach on classical RMDP examples from the literature scaling up to thousands of states."}],"scopus_import":"1","author":[{"full_name":"Asadi, Ali","first_name":"Ali","id":"02d96aae-000e-11ec-b801-cadd0a5eefbb","last_name":"Asadi"},{"last_name":"Chatterjee","orcid":"0000-0002-4561-241X","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","full_name":"Chatterjee, Krishnendu"},{"last_name":"Kafshdar Goharshadi","orcid":"0000-0002-8595-0587","id":"103b4fa0-896a-11ed-bdf8-87b697bef40d","full_name":"Kafshdar Goharshadi, Ehsan","first_name":"Ehsan"},{"orcid":"0009-0007-5253-9170","last_name":"Karrabi","full_name":"Karrabi, Mehrdad","first_name":"Mehrdad","id":"67638922-f394-11eb-9cf6-f20423e08757"},{"last_name":"Shafiee","full_name":"Shafiee, Ali","first_name":"Ali","id":"2783031a-7378-11f0-b2d0-f17f1db2ebad"}],"page":"36137-36145","quality_controlled":"1","project":[{"grant_number":"863818","call_identifier":"H2020","name":"Formal Methods for Stochastic Models: Algorithms and Applications","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E"}],"_id":"21717","doi":"10.1609/aaai.v40i43.40931","publication":"Proceedings of the 40th AAAI Conference on Artificial Intelligence","type":"conference","intvolume":" 40","arxiv":1,"external_id":{"arxiv":["2505.04539"]},"citation":{"short":"A.

Specifically, our framework dynamically maintains a variant of the hierarchical 𝑗-tree decomposition of [Madry FOCS’10], achieving a poly-logarithmic approximation factor to the graph’s cut structure and supporting edge updates in 𝑂(𝑛𝜀) amortized update time, for any arbitrarily small constant 𝜀 ∈(0,1).\r\nConsequently, we obtain new trade-offs between approximation and update/query time for fundamental cut-based optimization problems in the fully dynamic setting, including all-pairs minimum cuts, sparsest cut, multi-way cut, and multi-cut. For the last three problems, these trade-offs give the first fully-dynamic algorithms achieving poly-logarithmic approximation in sub-linear time per operation.\r\nThe main technical ingredient behind our dynamic hierarchy is a dynamic cut-sparsifier algorithm that can handle vertex splits with low recourse. This is achieved by white-boxing the dynamic cut sparsifier construction of [Abraham et al. FOCS’16], based on forest packing, together with new structural insights about the maintenance of these forests under vertex splits.

They are force-free and can be described as hydrodynamic force dipoles: pushers or pullers. This modelling description is broadly used in biological physics and active matter research, and it has successfully predicted, for example, the superfluid behaviour of suspensions of pushers or the bend instability and emergence of turbulent flows in active nematics. However, this description accounts only for the translational motion of the swimming body and neglects the effects of hydrodynamic torque dipoles, which are relevant to bacteria with rotary motor-driven flagella, such as swimming Escherichia coli. Here we show that the torque dipole of confined swimming E. coli can power the persistent rotation of symmetric discs. The torque dipole leads to a traction force on the discs, an additive mechanism that is both contactless and independent of the orientation of the bacteria. Our results indicate that the torque dipole of swimming E. coli is notable in confined geometries, which is relevant to bacterial transport through porous materials, biofilms and the development of chiral fluids.","lang":"eng"}],"day":"27","date_created":"2026-04-12T22:01:51Z","title":"The hydrodynamic torque dipole from rotary bacterial flagella powers symmetric discs","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://doi.org/10.1038/s41567-026-03189-4","open_access":"1"}],"scopus_import":"1","doi":"10.1038/s41567-026-03189-4","_id":"21721","project":[{"_id":"bdac72da-d553-11ed-ba76-eae56e802b74","name":"VULCAN: matter, powered from within","grant_number":"101086998"}],"quality_controlled":"1","author":[{"first_name":"Daniel B","full_name":"Grober, Daniel B","id":"c692f879-718d-11ee-81f0-da7caa79c783","last_name":"Grober"},{"first_name":"Tanumoy","full_name":"Dhar, Tanumoy","last_name":"Dhar"},{"full_name":"Saintillan, David","first_name":"David","last_name":"Saintillan"},{"id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","first_name":"Jérémie A","full_name":"Palacci, Jérémie A","last_name":"Palacci","orcid":"0000-0002-7253-9465"}],"acknowledgement":"We thank E.

The most basic objective is the reachability objective, where a target set must be eventually visited, and the more general parity objectives can model all omega-regular specifications. For such objectives, the computational analysis problems are the following: (a) qualitative analysis that asks whether the objective can be satisfied with probability 1 (almost-sure winning) or probability arbitrarily close to 1 (limit-sure winning); and (b) quantitative analysis that asks for the approximation of the optimal probability of satisfying the objective. For general POMDPs, almost-sure analysis for reachability objectives is EXPTIME-complete, but limit-sure and quantitative analyses for reachability objectives are undecidable; almost-sure, limit-sure, and quantitative analyses for parity objectives are all undecidable. A special class of POMDPs, called revealing POMDPs, has been studied recently in several works, and for this subclass the almost-sure analysis for parity objectives was shown to be EXPTIME-complete.

Open clusters offer the most straightforward way to empirically determine the IFMR, as their well-defined ages allow for direct progenitor lifetime estimates. We construct the most comprehensive open cluster WD IFMR to date by combining new spectroscopy of 22 WDs with an extensive literature review of WDs with strong cluster associations. To minimize systematics, we restrict our analysis to spectroscopically confirmed hydrogen-atmosphere (DA) WDs consistent with single-stellar origins. We separately analyze a subset with reliable Gaia-based astrometric membership assessments, as well as a full sample that adds WDs with strong cluster associations whose membership cannot be reliably assessed with Gaia. The Gaia-based sample includes 69 spectroscopically confirmed DA WDs, more than doubling the sample size of previous Gaia-based open cluster IFMRs. The full sample, which includes 53 additional literature WDs,\r\nincreases the total number of cluster WDs by over 50% relative to earlier works. We provide functional forms for both the Gaia-based and full-sample IFMRs. The Gaia-based result useful for Mi � 2.67 M⊙ is Mf = [0.179 0.100H (Mi 3.84 M )] × (Mi 3.84 M ) + 0.628 M , where H(x) is the Heaviside step function. Comparing our IFMR to recent literature, we identify significant deviations from best-fit IFMRs derived from both Gaia-based volume-limited samples of field WDs and double WD binaries, with the largest discrepancy occurring for initial masses of about 5 M⊙.","lang":"eng"}],"day":"01","date_created":"2026-04-12T22:01:52Z","scopus_import":"1"},{"publication":"Nature Materials","type":"journal_article","citation":{"chicago":"Baykusheva, Denitsa Rangelova, Deven Carmichael, Clara S.

Floquet engineering, the coherent dressing of quantum states with periodic non-resonant optical fields, has become an important strategy for quantum control. Most applications to solid-state systems have targeted weakly interacting or single-ion states, leaving the manipulation of many-body wavefunctions largely unexplored. Here we use Floquet engineering to achieve quantum control of a strongly correlated Hubbard exciton in the one-dimensional Mott insulator Sr2CuO3. A non-resonant mid-infrared optical field coherently dresses the exciton wavefunction, driving its rotation between bright and dark states. We use resonant third-harmonic generation to quantify ultrafast π/2 rotations on the Bloch sphere spanned by these exciton states. Our work advances the quest towards programmable control of correlated states and exciton-based quantum sensing.","lang":"eng"}],"day":"09","date_created":"2026-04-12T22:01:53Z","OA_place":"repository","publication_identifier":{"eissn":["1476-4660"],"issn":["1476-1122"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"Preprint","OA_type":"green","year":"2026","status":"public","corr_author":"1","month":"03","date_published":"2026-03-09T00:00:00Z","article_type":"original","date_updated":"2026-04-13T07:29:34Z","publication_status":"epub_ahead","publisher":"Springer Nature","oa":1,"article_processing_charge":"No","department":[{"_id":"DeBa"}]},{"acknowledged_ssus":[{"_id":"LifeSc"}],"publisher":"Royal Society of Chemistry","date_published":"2026-04-10T00:00:00Z","month":"04","article_type":"original","publication_status":"epub_ahead","date_updated":"2026-04-16T05:44:49Z","department":[{"_id":"StFr"}],"article_processing_charge":"No","OA_type":"closed access","oa_version":"None","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_identifier":{"issn":["2050-750X"],"eissn":["2050-7518"]},"corr_author":"1","year":"2026","status":"public","pmid":1,"scopus_import":"1","abstract":[{"lang":"eng","text":"Hydrogen peroxide (H2O2) is a crucial member of the reactive oxygen species (ROS) family, playing roles in cellular signalling and immune responses in human health. Moreover, it is a potential biomarker of diabetes when present in aberrant concentrations. Therefore, monitoring trace levels of H2O2 has become a research hotspot for analytical and sensor chemists. In this context, we report a rhodamine-based fluorescent probe (RN), which shows excellent fluorescent enhancement at 555 nm upon the addition of H2O2 along with a low limit of detection (LOD) of 0.67 ppm and fast response (∼2 min). The probe is highly selective for H2O2, showing no fluorescence enhancement with other ROS. RN is synthesised in a one-pot chemical reaction using rhodamine 6G (R6G) and 4,7,10-trioxa-1,13-tridecanediamine (TTDA). H2O2 detection in pre-treated milk samples proves its real-world viability. We found that RN shows low cytotoxicity, which allowed us to successfully explore its potential to monitor H2O2 generation in a diabetic L929 skin cell line and diabetic mice liver tissue.

These mysterious systems offer unique insight into the complex interplay between magnetic fields, stellar rotation and atmospheric activity in single white dwarfs. DAHe stars have detectable magnetic fields through Zeeman-split spectral lines, whereas DAe stars lack such splitting. We report the first discovery and characterization of magnetism in the DAe white dwarf WD J165335.21−100116.33 with new time-resolved spectropolarimetry from FORS2. We detect a weak but variable longitudinal magnetic field with values Bz > −9.2 ± 2.4 kG and Bz < −2.2 ± 1.0 kG. Independent ZTF and ATLAS photometry reveal a consistent period of P = 80.3070 ± 0.0007 h. Time-resolved optical spectroscopy obtained with six ground-based instruments demonstrates strong modulation in the strength of the Hα and Hβ Balmer line emission with P = 80.2922 ± 0.0108 h. The photometric flux and Balmer emission strength vary in antiphase, with the strongest magnetic detections coinciding with phases of low photometric flux and strong line emission. These characteristicssupport the theory that a magnetically active, temperature-inverted spot/region is producing an optically thin chromospheric emission region. Comparison with other DAe and DAHe white dwarfsreveals all systems have a strikingly similar antiphase phenomenology, reinforcing the theory that they are subject to a unified physical mechanism. With the detection of a weak magnetic field, we reclassify WD J165335.21−100116.33 as a low-field DAHe white dwarf.

How spinal circuits and their cell types evolved to support this transition remains unclear. We leverage frog metamorphosis, which recapitulates this transition within a single organism, to define how spinal circuits generate aquatic versus terrestrial motor patterns. At swim stages, spinal architecture is uniform, with a transcriptionally and anatomically homogeneous motor and interneurons. As limbs develop and their movement complexifies, spinal circuits expand in neuron number and subtype diversity. This expansion is most pronounced for V1 inhibitory neurons, which increase ∼70-fold and diversify into transcriptionally distinct subtypes. Disrupting transcription factors defining emerging motor and V1 populations reveals molecular segregation between swim and limb circuits, highlighting the role of subtype diversity in motor coordination. A multifold increase in inhibitory neuron diversity thus underlies the tail-to-limb locomotor transition, providing a framework for spinal circuit adaptation during vertebrate evolution.","lang":"eng"}],"date_created":"2026-04-19T22:07:43Z","DOAJ_listed":"1","title":"Multifold increase in spinal inhibitory cell types with emergence of limb movement","language":[{"iso":"eng"}],"file_date_updated":"2026-05-04T12:20:10Z","volume":45,"pmid":1,"scopus_import":"1","doi":"10.1016/j.celrep.2026.117227","_id":"21746","project":[{"_id":"ebb66355-77a9-11ec-83b8-b8ac210a4dae","grant_number":"101041551","name":"Development and Evolution of Tetrapod Motor Circuits"},{"name":"Stem Cell Modulation in Neural Development and Regeneration/ P14-Swim-to-limb transition: cell type to connection diversity","grant_number":"F7814","_id":"8da85f50-16d5-11f0-9cad-eab8b0ff6c9e"},{"name":"Tools for automation and feedback microscopy","grant_number":"CZI01","_id":"c08e9ad1-5a5b-11eb-8a69-9d1cf3b07473"},{"_id":"bd73af52-d553-11ed-ba76-912049f0ac7a","grant_number":"FTI21-D-046","name":"Development of V1 interneuron diversity during swim-to-walk transition of Xenopus metamorphosis"}],"quality_controlled":"1","author":[{"last_name":"Vijatovic","id":"cf391e77-ec3c-11ea-a124-d69323410b58","full_name":"Vijatovic, David","first_name":"David"},{"last_name":"Toma","id":"2f73f876-f128-11eb-9611-b96b5a30cb0e","first_name":"Florina Alexandra ","full_name":"Toma, Florina Alexandra "},{"full_name":"Ignatyev, Y","first_name":"Y","last_name":"Ignatyev"},{"last_name":"Harrington","orcid":"0009-0008-0158-4032","id":"a8144562-32c9-11ee-b5ce-d9800628bda2","first_name":"Zoe P","full_name":"Harrington, Zoe P"},{"last_name":"Sommer","orcid":"0000-0003-1216-9105","id":"4DF26D8C-F248-11E8-B48F-1D18A9856A87","first_name":"Christoph M","full_name":"Sommer, Christoph M"},{"last_name":"Hauschild","orcid":"0000-0001-9843-3522","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","first_name":"Robert","full_name":"Hauschild, Robert"},{"id":"7a231d52-e216-11ee-a0bb-8acd55f8f1f0","first_name":"Matthijs Geert","full_name":"Smits, Matthijs Geert","last_name":"Smits"},{"last_name":"Dalla Vecchia","id":"02a7a869-ff06-11ed-a87f-86649d6077e5","first_name":"Marco","full_name":"Dalla Vecchia, Marco"},{"last_name":"Trevisan","full_name":"Trevisan, Alexandra J.","first_name":"Alexandra J."},{"first_name":"Phillip","full_name":"Chapman, Phillip","last_name":"Chapman"},{"id":"1cf464b2-dc7d-11ea-9b2f-f9b1aa9417d1","full_name":"Julseth, Mara","first_name":"Mara","last_name":"Julseth"},{"full_name":"Brenner-Morton, Susan","first_name":"Susan","last_name":"Brenner-Morton"},{"full_name":"Gabitto, Mariano I.","first_name":"Mariano I.","last_name":"Gabitto"},{"last_name":"Dasen","first_name":"Jeremy S.","full_name":"Dasen, Jeremy S."},{"first_name":"Jay B.","full_name":"Bikoff, Jay B.","last_name":"Bikoff"},{"last_name":"Sweeney","orcid":"0000-0001-9242-5601","id":"56BE8254-C4F0-11E9-8E45-0B23E6697425","full_name":"Sweeney, Lora Beatrice Jaeger","first_name":"Lora Beatrice Jaeger"}],"citation":{"chicago":"Vijatovic, David, Florina Alexandra Toma, Y Ignatyev, Zoe P Harrington, Christoph M Sommer, Robert Hauschild, Matthijs Geert Smits, et al. “Multifold Increase in Spinal Inhibitory Cell Types with Emergence of Limb Movement.” Cell Reports.

Here, we present an alternate realization that avoids the complexity of homodyne measurements and potential loopholes in their implementation. We violate a Bell inequality by performing joint measurements on two copies of the same single-photon entangled state, where one photon acts as a phase reference for the other, making it self-referential. We observe CHSH parameters of 2.71 = 0.09 and 2.23 = 0.07, depending on the joint measurements implemented. This offers a perspective on single-photon nonlocality and a more accessible experimental route, potentially applicable to general mode-entangled states in diverse platforms."}],"day":"20","date_created":"2026-04-19T22:07:44Z","publication":"Optica","type":"journal_article","arxiv":1,"intvolume":" 13","acknowledgement":"European Union ERC (101071779 (GRAVITES)); European Union Horizon 2020 Research and Innovation Programme (899368 (EPIQUS)); European Union Horizon 2020 Research and Innovation Programme Marie Sklodowska-Curie (956071 (AppQInfo)); European Union HORIZON Europe Research and Innovation Programme (101135288 (EPIQUE)); FWF Austrian Science Fund (10.55776/COE1 (Quantum Science Austria), 10.55776/F71 (BeyondC), 10.55776/FG5 (Research Group 5)); United States Air Force Office of Scientific Research (FA9550-21-1-0355 (Q-Trust), FA8655-23-1-7063 (TIQI)).","citation":{"ieee":"D.
