While Bitcoin,\r\nbased on Proof-of-Work (PoW), was the first protocol in this model, significant\r\nresearch has focused on permissionless protocols using alternative physical resources,\r\nspecifically Proof-of-Space (PoSpace) and Verifiable Delay Functions (VDFs). This\r\nthesis investigates the theoretical limits and design space of longest-chain protocols in\r\nthe fully permissionless and dynamically available settings using these three resources.\r\nFirst, we address the feasibility of blockchains relying solely on storage as a resource.\r\nWe prove a fundamental impossibility result: there exists no secure longest-chain\r\nprotocol based exclusively on Proof-of-Space in the fully permissionless or dynamically\r\navailable settings. Further, we quantify the adversarial capabilities required to execute\r\na double-spend attack. Our result formally justifies the necessity of coupling PoSpace\r\nwith time-dependent primitives (such as VDFs) or to move to less permissive settings\r\n(quasi-permissionless or permissioned) to ensure security.\r\nSecond, we generalize Nakamoto-like heaviest chain consensus to protocols utilizing\r\ncombinations of multiple physical resources. We analyze chain selection rules governed\r\nby a weight function Γ(S, V,W), which assigns weight to blocks based on recorded\r\nSpace (S), VDF speed (V ), and Work (W). We provide a complete classification\r\nof secure weight functions, proving that a weight function is secure against private\r\ndouble-spend attacks if and only if it is homogeneous in the timed resources (V,W)\r\nand sub-homogeneous in S. This framework unifies existing protocols like Bitcoin and\r\nChia under a single theoretical model and provides a powerful tool for designing new\r\nlongest-chain blockchains from a mix of physical resources.","lang":"eng"}],"month":"03","license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","related_material":{"record":[{"status":"public","id":"21134","relation":"part_of_dissertation"},{"relation":"part_of_dissertation","id":"20587","status":"public"}]},"department":[{"_id":"GradSch"},{"_id":"KrPi"}],"OA_place":"publisher","_id":"21651","file_date_updated":"2026-04-15T07:37:25Z","year":"2026","publication_identifier":{"isbn":["978-3-99078-078-7"],"issn":["2663-337X"]},"degree_awarded":"PhD","title":"On secure chain selection rules from physical resources in a permissionless setting","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode","short":"CC BY-NC-SA (4.0)","name":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","image":"/images/cc_by_nc_sa.png"},"status":"public","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","day":"04","doi":"10.15479/AT-ISTA-21651","date_published":"2026-03-04T00:00:00Z","oa_version":"Published Version","ddc":["000"],"publisher":"Institute of Science and Technology Austria","type":"dissertation","article_processing_charge":"No","date_created":"2026-04-02T09:31:34Z","has_accepted_license":"1","supervisor":[{"id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-9139-1654","first_name":"Krzysztof Z","full_name":"Pietrzak, Krzysztof Z","last_name":"Pietrzak"}],"citation":{"short":"M.A. Baig, On Secure Chain Selection Rules from Physical Resources in a Permissionless Setting, Institute of Science and Technology Austria, 2026.","ama":"Baig MA.

In this Letter, we propose a new formation scenario for black hole (BH) + Be star binaries (hereafter BHBe binaries), where the Be star is produced through the wind Roche lobe overflow (WRLOF) mechanism. 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.","lang":"eng"}],"month":"01","publication":"The Astrophysical Journal Letters","department":[{"_id":"YlGo"}],"OA_place":"publisher","_id":"21714","scopus_import":"1","file_date_updated":"2026-04-16T06:24:30Z","year":"2026","arxiv":1,"citation":{"apa":"Li, Z., Jia, S., Wei, D., Ge, H., Chen, H., Zhang, Y., … Han, Z.

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"}],"corr_author":"1","date_updated":"2026-04-16T06:20:23Z","author":[{"last_name":"Grober","first_name":"Daniel B","full_name":"Grober, Daniel B","id":"c692f879-718d-11ee-81f0-da7caa79c783"},{"last_name":"Dhar","full_name":"Dhar, Tanumoy","first_name":"Tanumoy"},{"first_name":"David","full_name":"Saintillan, David","last_name":"Saintillan"},{"full_name":"Palacci, Jérémie A","first_name":"Jérémie A","last_name":"Palacci","orcid":"0000-0002-7253-9465","id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d"}],"quality_controlled":"1","article_type":"original","oa":1,"OA_type":"hybrid","publication_status":"epub_ahead","language":[{"iso":"eng"}],"citation":{"ieee":"D.

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.

The evolutionary success of these populations is fundamentally dictated by the organization of genetic variation—the genomic architecture—in the face of severe demographic constraints, such as the founder effects and genetic bottlenecks that frequently accompany colonization. A central question in evolutionary biology is whether rapid adaptation relies on major-effect loci, such as chromosomal inversions, or on many small-effect loci dispersed across the genome. Furthermore, the genomic architecture strongly influences the extent to which evolutionary outcomes are predictable. Using introduced populations of the marine snail, Littorina saxatilis, as a model, this thesis investigates how genetic variation and genomic structure drive adaptation following introduction. We employed a population genomics approach on experimentally and accidentally introduced populations to dissect the specific genomic features that underpin divergence in newly colonized environments.\r\n\r\nIn Chapter 2, we tested the predictability of local adaptation through an uncommon 30-year transplant experiment in nature. By distinguishing allele and chromosomal inversion frequency changes from neutral expectations, we found that evolutionary change was highly predictable at the macro-scale (phenotypes and chromosomal inversions), but less robust at the level of individual collinear loci. This result demonstrates that evolution can be predictable when a population possesses sufficient standing genetic variation (SGV), with chromosomal inversions acting as key integrated units that facilitate a rapid response to selection. Building on this, Chapter 3 applied whole-genome sequencing to three accidentally introduced populations (Venice, San Francisco, and Redwood City) to investigate their likely source and genomic patterns of divergence. We identified genomic regions of remarkable divergence potentially associated with local adaptation, and likely fuelled by SGV, while explicitly acknowledging the difficulty in disentangling selection signals from the genome-wide effects of demographic processes. Furthermore, we found that the divergence patterns relied extensively on the collinear genome in these introduced populations, and less clearly on the chromosomal inversions. This observation contrasts with local adaptation observed in the experimental system that relied on both collinear loci and highly selected chromosomal inversions, highlighting how demographic history and genomic architecture influence the detectable signature of local adaptation.\r\n\r\nA major limitation to conducting large-scale comparative evolutionary studies is the lack of data standardization, which prevents the integration of community knowledge and high-resolution environmental and genetic data. Chapter 4 addresses this by developing a community database for the Littorina system. This platform implements standardized protocols for the integration of diverse phenotypic and environmental data from multiple Littorina species. Likewise, the platform also centralizes the availability of associated genomic data through links to external repositories. This database represents a crucial tool to test complex, large-scale evolutionary hypotheses.\r\n\r\nCollectively, this thesis strongly reinforces the fundamental importance of SGV as the raw material for successful local adaptation, a conclusion supported by evidence in both experimental and accidental introductions. Furthermore, this work highlights the critical role of the genomic architecture—specifically chromosomal inversions—in driving the predictability and effectiveness of adaptive responses. Our findings underscore how the interplay between SGV and genomic architecture dictates the trajectory and detectability of evolution in colonizing populations, while simultaneously providing a necessary tool to advance comparative evolutionary genomics in emerging model organisms."}],"month":"01","related_material":{"record":[{"id":"18498","status":"public","relation":"research_data"},{"id":"18491","status":"public","relation":"part_of_dissertation"}]},"department":[{"_id":"GradSch"},{"_id":"NiBa"}],"_id":"20991","OA_place":"publisher","file_date_updated":"2026-01-16T13:08:59Z","year":"2026","file":[{"date_updated":"2026-01-16T12:25:13Z","access_level":"closed","file_name":"2026_Garcia_Diego_Thesis.docx","file_size":22456421,"content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document","file_id":"20996","creator":"dgarciac","date_created":"2026-01-16T12:25:13Z","relation":"source_file","checksum":"841f1bc073d667125729b2a017f8c37a"},{"access_level":"open_access","date_updated":"2026-01-16T12:25:13Z","file_name":"2026_Garcia_Diego_Thesis.pdf","file_size":9556719,"creator":"dgarciac","file_id":"20997","content_type":"application/pdf","success":1,"relation":"main_file","date_created":"2026-01-16T12:25:13Z","checksum":"a1f33d4f183ce7072eee42a6ccf5340b"},{"file_name":"2026_DiegoGarcia_LittorinaDB

This platform provides an integrated and compact method to generate spin-polarized electrons, implementable with millimeter scale chips and tabletop lasers."}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1103/3c1m-d3hh"}],"year":"2026","scopus_import":"1","_id":"21555","OA_place":"publisher"},{"date_updated":"2026-04-27T10:01:35Z","article_type":"original","quality_controlled":"1","extern":"1","author":[{"last_name":"Cheng","full_name":"Cheng, Dali","first_name":"Dali"},{"first_name":"Heming","full_name":"Wang, Heming","last_name":"Wang"},{"first_name":"Janet","full_name":"Zhong, Janet","last_name":"Zhong"},{"last_name":"Lustig","full_name":"Lustig, Eran","first_name":"Eran"},{"id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","first_name":"Charles","full_name":"Roques-Carmes, Charles","last_name":"Roques-Carmes"},{"first_name":"Shanhui","full_name":"Fan, Shanhui","last_name":"Fan"}],"abstract":[{"text":"Non-Hermiticity naturally arises in physical systems that exchange energy with their environment. The presence of non-Hermiticity leads to many topological physics phenomena and device applications. In the non-Hermitian energy band theory, the foundation of these physics and applications, both energies and wave vectors take complex values. The energy bands thus become a Riemann surface, and such an energy-band Riemann surface underlies all important signatures of non-Hermitian topology. Despite a long history and recent theoretical interests, the energy-band Riemann surface has not been experimentally studied. Here, we provide a photonic observation of the energy-band Riemann surface of a non-Hermitian system. This is achieved by a tunable imaginary gauge transformation in photonic synthetic frequency dimensions. From measured topologies of the Riemann surface, we reveal the complex-energy winding, the open-boundary-condition spectrum, the generalized Brillouin zone, and the branch points. Our findings demonstrate a unified framework in the studies of diverse effects in non-Hermitian topological physics through an experimental observation of energy-band Riemann surfaces.","lang":"eng"}],"month":"03","publication":"Science Advances","scopus_import":"1","year":"2026","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1126/sciadv.aec8239"}],"OA_place":"publisher","_id":"21583","title":"Experimental observation of energy-band Riemann surface","DOAJ_listed":"1","publication_identifier":{"issn":["2375-2548"]},"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"18","issue":"12","oa_version":"Published Version","doi":"10.1126/sciadv.aec8239","date_published":"2026-03-18T00:00:00Z","intvolume":"        12","volume":12,"type":"journal_article","article_processing_charge":"No","publisher":"American Association for the Advancement of Science","date_created":"2026-03-30T12:22:48Z","citation":{"ama":"Cheng D, Wang H, Zhong J, Lustig E, Roques-Carmes C, Fan S.

We demonstrate that the dispersion relation ω(k), obtained from dynamical density functional theory for the uniform density system, is a highly versatile tool for predicting where in the phase diagram complex crystals form. The sign of ω(k) determines whether density modes with wave number k grow or decay over time. We demonstrate the predictive power by investigating the complex phase behavior of particles interacting via core-shoulder pair potentials. With complementary Monte Carlo simulations, we show that regions of the phase diagram where ωðkÞ has one or several unstable (growing) wave numbers are also where crystalline phases occur. Going further, by tuning these\r\nunstable wave numbers via the interaction-potential and state-point parameters, we design systems with quasicrystals in the phase diagram. We identify a system with a certain shoulder range exhibiting at least ten different phases. Our general approach accelerates considerably the mapping of complex phase diagrams, crucial for the design of new materials.","lang":"eng"}],"publication":"Physical Review Letters","month":"04","department":[{"_id":"AnSa"},{"_id":"GradSch"}],"OA_place":"publisher","_id":"21764","scopus_import":"1","file_date_updated":"2026-04-28T06:58:40Z","year":"2026","article_type":"original","file":[{"access_level":"open_access","date_updated":"2026-04-28T06:58:40Z","file_name":"2026_PhysicalReviewLetters_Wassermair.pdf","file_id":"21769","content_type":"application/pdf","creator":"dernst","file_size":4336488,"success":1,"checksum":"8ffb139122a185fcddbe6a9c901a287c","date_created":"2026-04-28T06:58:40Z","relation":"main_file"}],"quality_controlled":"1","author":[{"id":"23d132c4-4e98-11ef-b275-9e8d4cd8c917","first_name":"Michael","full_name":"Wassermair, Michael","last_name":"Wassermair","orcid":"0009-0003-6339-4051"},{"last_name":"Kahl","full_name":"Kahl, Gerhard","first_name":"Gerhard"},{"last_name":"Roth","first_name":"Roland","full_name":"Roth, Roland"},{"last_name":"Archer","first_name":"Andrew J.","full_name":"Archer, Andrew J."}],"date_updated":"2026-04-28T07:03:48Z","issue":"14","PlanS_conform":"1","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"10","doi":"10.1103/nbvt-fgjy","date_published":"2026-04-10T00:00:00Z","oa_version":"Published Version","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"title":"Navigating complex phase diagrams in soft matter systems","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"}},{"article_number":"045604","OA_type":"closed access","language":[{"iso":"eng"}],"publication_status":"published","citation":{"ieee":"M.

The fact that particles can become highly charged as a result of this effect has significant consequences for many settings, both in nature and industry, such as thunderstorms, volcanic eruptions, particle aggregation during meteorite and planet formation, and the clogging of industrial granular systems. Toward understanding these systems, great efforts have been made to develop precise in situ measurements for particle charge, e.g., to determine ensemble charge distributions or measure exchange during individual contacts. Here, we present experimental results concerning the particle size scaling of the stationary-state charge distributions of oxide particles in the sub-millimeter range. We measure the charge distributions for large ensembles of monodisperse ZrO2:SiO2 composite spheres, ranging from 172 to 545µ⁢m in diameter. These distributions are non-Gaussian and collapse to a single master curve when plotted as functions of the surface charge density Σ=𝑞/4⁢𝜋⁢𝑅2. X-ray fluorescence and atomic force microscopy measurements show that the differences in the measured charge distributions are not due to variations in chemical composition or surface roughness, but rather to size alone. Our findings provide constraints on microscopic models for charge exchange, namely that they should lead to steady-state distributions that are non-Gaussian and scale in a specific way with particle size.","lang":"eng"}],"date_updated":"2026-04-28T07:13:56Z","author":[{"last_name":"Lara","full_name":"Lara, Macarena","first_name":"Macarena"},{"last_name":"Flores","full_name":"Flores, Marcos","first_name":"Marcos"},{"first_name":"Gustavo","full_name":"Castillo, Gustavo","last_name":"Castillo"},{"last_name":"Tassara","first_name":"Santiago","full_name":"Tassara, Santiago"},{"id":"3A1FFC16-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2299-3176","last_name":"Waitukaitis","full_name":"Waitukaitis, Scott R","first_name":"Scott R"},{"last_name":"Mujica","first_name":"Nicolás","full_name":"Mujica, Nicolás"}],"article_type":"original","quality_controlled":"1"},{"title":"Symplectic structures on the space of space curves","publication_identifier":{"eissn":["1432-1467"],"issn":["0938-8974"]},"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"15","issue":"2","PlanS_conform":"1","oa_version":"Published Version","doi":"10.1007/s00332-026-10266-8","date_published":"2026-04-15T00:00:00Z","date_updated":"2026-04-28T09:59:01Z","quality_controlled":"1","file":[{"file_name":"2026_JourNonlinearScience_Bauer.pdf","access_level":"open_access","date_updated":"2026-04-28T09:55:32Z","success":1,"checksum":"760de2631b6fd7d57bcd5115ed36c0a2","date_created":"2026-04-28T09:55:32Z","relation":"main_file","file_id":"21770","content_type":"application/pdf","creator":"dernst","file_size":1108518}],"article_type":"original","author":[{"first_name":"Martin","full_name":"Bauer, Martin","last_name":"Bauer"},{"id":"6F7C4B96-A8E9-11E9-A7CA-09ECE5697425","last_name":"Ishida","full_name":"Ishida, Sadashige","first_name":"Sadashige","orcid":"0000-0002-3121-3100"},{"full_name":"Michor, Peter W.","first_name":"Peter W.","last_name":"Michor"}],"related_material":{"record":[{"relation":"earlier_version","id":"17361","status":"public"}]},"department":[{"_id":"GradSch"},{"_id":"ChWo"}],"abstract":[{"text":"We present symplectic structures on the shape space of unparameterized space curves that generalize the classical Marsden–Weinstein structure.

We also point out why extending this result to smoother quotients remains an intriguing challenge."}]},{"ddc":["520"],"intvolume":"       706","publisher":"EDP Sciences","type":"journal_article","volume":706,"article_processing_charge":"Yes","acknowledgement":"We thank Lynne Hillenbrand and Soumyadeep Bhattacharjee for helpful discussions, and Kishalay De for his help with the WIRC\r\nreduction pipeline.

The merger remnants that do not explode in a Type Ia supernova are expected to initially be rapidly rotating and highly magnetized. In this work, we present our discovery of the variable white dwarf ZTF J200832.79+444939.67, hereafter ZTF J2008+4449, as a likely merger remnant showing signs of circumstellar material without a stellar or substellar companion. The nature of ZTF J2008+4449 as a merger remnant is supported by its physical properties: it is hot (35 500 ± 300 K) and massive (1.12 ± 0.03 M\r\n                    <jats:sub>⊙</jats:sub>\r\n                    ), rapidly rotating with a period of ≈6.6 minutes, and likely possesses exceptionally strong magnetic fields (∼400−600 MG) at its surface. Remarkably, we detect a significant period derivative of (1.80 ± 0.09)×10\r\n                    <jats:sup>−12</jats:sup>\r\n                    s/s, indicating that the white dwarf is spinning down, and a soft X-ray emission that is inconsistent with photospheric emission. As the presence of a mass-transferring stellar or brown dwarf companion is excluded by infrared photometry, the detected spin-down and X-ray emission could be tell-tale signs of a magnetically driven wind or of interaction with circumstellar material, possibly originating from the fallback of gravitationally bound merger ejecta or from the tidal disruption of a planetary object. We also detect Balmer emission, which requires the presence of ionized hydrogen in the vicinity of the white dwarf, showing Doppler shifts as high as ≈2000 km s\r\n                    <jats:sup>−1</jats:sup>\r\n                    .

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.","lang":"eng"}],"month":"03","publication":"Nature","related_material":{"link":[{"url":"https://ista.ac.at/en/news/colliding-dust-and-the-sparks-of-creation/","relation":"press_release","description":"News on ISTA website"}]},"department":[{"_id":"ScWa"},{"_id":"GradSch"},{"_id":"LifeSc"}],"language":[{"iso":"eng"}],"pmid":1,"publication_status":"published","citation":{"ista":"Grosjean GM, Ostermann M, Sauer M, Hahn M, Pichler CM, Fahrnberger F, Pertl F, Balazs D, Link MM, Kim SH, Schrader DL, Blanco A, Gracia F, Mujica N, Waitukaitis SR. 2026.

Here we show that in zebrafish, the geometry of the fertilized egg—specifically its curvature and volume—serves as a critical initial condition triggering a cascade of events that influence development. The embryo geometry guides patterned asymmetric cell divisions in the blastoderm, generating radial gradients of cell volume and nucleocytoplasmic ratio. These gradients generate mitotic phase waves, with the nucleocytoplasmic ratio determining individual cell cycle periods independently of other cells. We demonstrate that reducing cell autonomy reshapes these waves, emphasizing the instructive role of geometry-derived volume patterns in setting the intrinsic period of the cell cycle oscillator. In addition to organizing cell cycles, early embryo geometry spatially patterns zygotic genome activation at the midblastula transition, a key step in establishing embryonic autonomy. Disrupting the embryo shape alters the zygotic genome activation pattern and causes ectopic germ layer specification, underscoring the developmental significance of geometry. Together, our findings reveal a symmetry-breaking function of early embryo geometry in coordinating cell cycle and transcriptional patterning.","lang":"eng"}],"department":[{"_id":"EdHa"},{"_id":"CaHe"}],"related_material":{"link":[{"description":"News on ISTA website","url":"https://ista.ac.at/en/news/geometry-shapes-life/","relation":"research_data"}]},"_id":"21015","OA_place":"publisher","year":"2026","scopus_import":"1","file_date_updated":"2026-01-21T08:21:11Z","author":[{"first_name":"Nikhil","full_name":"Mishra, Nikhil","last_name":"Mishra","orcid":"0000-0002-6425-5788","id":"C4D70E82-1081-11EA-B3ED-9A4C3DDC885E"},{"last_name":"Li","full_name":"Li, Yuting I","first_name":"Yuting I","id":"ee7a5ca8-8b71-11ed-b662-b3341c05b7eb"},{"orcid":"0000-0001-6005-1561","full_name":"Hannezo, Edouard B","first_name":"Edouard B","last_name":"Hannezo","id":"3A9DB764-F248-11E8-B48F-1D18A9856A87"},{"id":"39427864-F248-11E8-B48F-1D18A9856A87","last_name":"Heisenberg","first_name":"Carl-Philipp J","full_name":"Heisenberg, Carl-Philipp J","orcid":"0000-0002-0912-4566"}],"article_type":"original","file":[{"checksum":"0ab7ac2fbcb61a364dba57152db64ed7","relation":"main_file","date_created":"2026-01-21T08:21:11Z","success":1,"content_type":"application/pdf","file_id":"21026","creator":"dernst","file_size":7335694,"file_name":"2026_NaturePhysics_Mishra.pdf","date_updated":"2026-01-21T08:21:11Z","access_level":"open_access"}],"quality_controlled":"1","date_updated":"2026-04-28T12:55:30Z","corr_author":"1","PlanS_conform":"1","day":"05","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","status":"public","date_published":"2026-01-05T00:00:00Z","doi":"10.1038/s41567-025-03122-1","oa_version":"Published Version","publication_identifier":{"issn":["1745-2473"],"issnl":[" 1745-2473"],"eissn":["1745-2481"]},"title":"Geometry-driven asymmetric cell divisions pattern cell cycles and zygotic genome activation in the zebrafish embryo","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"acknowledged_ssus":[{"_id":"PreCl"},{"_id":"Bio"},{"_id":"ScienComp"},{"_id":"LifeSc"}],"volume":22,"article_processing_charge":"Yes (via OA deal)","type":"journal_article","publisher":"Springer Nature","ec_funded":1,"acknowledgement":"We thank N.

Paradoxically, perovskites are also known for having very short exciton decay times. Here, we resolve this apparent contradiction by showing that key optoelectronic properties of perovskites can be explained by localized flexoelectric polarization confined to interfaces between domains of spontaneous strain. Using birefringence imaging, electrochemical staining, and zero-bias photocurrent measurements, we visualize the domain structure and directly probe the associated internal fields in nominally cubic single crystals of methylammonium lead bromide. We demonstrate that localized flexoelectric fields spatially separate electrons and holes to opposite sides of domain walls, exponentially suppressing recombination. Domain walls thus act as efficient mesoscopic transport channels for long-lived photocarriers, microscopically linking structural heterogeneity to charge transport and offering mechanistically informed design principles for perovskite solar-energy technologies."}],"publication":"Nature Communications","month":"02","scopus_import":"1","file_date_updated":"2026-03-02T14:27:56Z","year":"2026","OA_place":"publisher","_id":"21382","date_updated":"2026-04-28T12:12:46Z","quality_controlled":"1","file":[{"file_name":"2026_NatureComm_Rak.pdf","date_updated":"2026-03-02T14:27:56Z","access_level":"open_access","relation":"main_file","date_created":"2026-03-02T14:27:56Z","checksum":"dd7a98de892d0b5abefca7e290ca0f77","success":1,"file_size":2570918,"file_id":"21390","content_type":"application/pdf","creator":"dernst"}],"article_type":"original","author":[{"last_name":"Rak","first_name":"Dmytro","full_name":"Rak, Dmytro","id":"70313b46-47c2-11ec-9e88-cd79101918fe"},{"id":"40D8A3E6-F248-11E8-B48F-1D18A9856A87","last_name":"Lorenc","full_name":"Lorenc, Dusan","first_name":"Dusan"},{"id":"302BADF6-85FC-11EA-9E3B-B9493DDC885E","orcid":"0000-0001-7597-043X","first_name":"Daniel","full_name":"Balazs, Daniel","last_name":"Balazs"},{"full_name":"Zhumekenov, Ayan A.","first_name":"Ayan A.","last_name":"Zhumekenov"},{"full_name":"Bakr, Osman M.","first_name":"Osman M.","last_name":"Bakr"},{"orcid":"0000-0002-7183-5203","last_name":"Alpichshev","first_name":"Zhanybek","full_name":"Alpichshev, Zhanybek","id":"45E67A2A-F248-11E8-B48F-1D18A9856A87"}],"corr_author":"1","OA_type":"gold","article_number":"946","external_id":{"pmid":["41698893"]},"oa":1,"citation":{"chicago":"Rak, Dmytro, Dusan Lorenc, Daniel Balazs, Ayan A.

Here, we develop a new algorithmic paradigm based on approximate message passing (genomic vector approximate message passing [gVAMP]) for identifying DNA sequence variants associated with complex traits and common diseases in large-scale whole-genome sequencing (WGS) data. We show that gVAMP accurately localizes associations to variants with the correct frequency and position in the DNA, outperforming existing fine-mapping methods in selecting the appropriate genetic variants within WGS data. We then apply gVAMP to jointly model the relationship of tens of millions of WGS variants with human height in hundreds of thousands of UK Biobank individuals. We identify 59 rare variants and gene burden scores alongside many hundreds of DNA regions containing common variant associations and show that understanding the genetic basis of complex traits will require the joint analysis of hundreds of millions of variables measured on millions of people. The polygenic risk scores obtained from gVAMP have high accuracy (including a prediction accuracy of ∼46% for human height) and outperform current methods for downstream tasks such as mixed linear model association testing across 13 UK Biobank traits. In conclusion, gVAMP offers a scalable foundation for a wider range of analyses in WGS data."}],"corr_author":"1","date_updated":"2026-04-28T12:08:37Z","author":[{"id":"0b77531d-dbcd-11ea-9d1d-a8eee0bf3830","first_name":"Al","full_name":"Depope, Al","last_name":"Depope"},{"full_name":"Bajzik, Jakub","first_name":"Jakub","last_name":"Bajzik","id":"b995e25b-8c4b-11ed-a6d8-f71b7bcd6122"},{"id":"27EB676C-8706-11E9-9510-7717E6697425","orcid":"0000-0002-3242-7020","last_name":"Mondelli","first_name":"Marco","full_name":"Mondelli, Marco"},{"id":"E5D42276-F5DA-11E9-8E24-6303E6697425","last_name":"Robinson","first_name":"Matthew Richard","full_name":"Robinson, Matthew Richard","orcid":"0000-0001-8982-8813"}],"quality_controlled":"1","article_type":"original","oa":1,"article_number":"101162","OA_type":"gold","publication_status":"epub_ahead","language":[{"iso":"eng"}],"citation":{"short":"A.

However, more physical insight is needed before we can take full advantage of this vast design space to assemble nanostructures with complex form and function. Here we show how a substantial part of this design space can be quickly and comprehensively understood by identifying a class of thermodynamic constraints that act on it. These thermodynamic constraints form a high-dimensional convex polyhedron that determines which nanostructures can be assembled at high equilibrium yield and reveals limitations that govern the coexistence of structures. We validate our predictions through detailed, quantitative assembly experiments of nanoscale particles synthesized using DNA origami. Our results uncover physical relationships underpinning many-component programmable self-assembly in equilibrium and form the basis for robust inverse design, applicable to various systems from biological protein complexes to synthetic nanomachines."}],"month":"01","publication":"Nature Physics","related_material":{"link":[{"url":"https://ista.ac.at/en/news/behind-natures-blueprints/","relation":"press_release","description":"News on ISTA website"}]},"department":[{"_id":"CaGo"},{"_id":"GradSch"}],"OA_place":"publisher","_id":"21006","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1038/s41567-025-03120-3"}],"year":"2026"}]
