With ever-larger amounts of unstructured and limited labels, organizing and reconciling information from different sources and modalities is a central challenge in machine learning. This cutting-edge tutorial aims to introduce the multimodal entailment task, which can be useful for detecting semantic alignments when a single modality alone does not suffice for a whole content understanding. Starting with a brief overview of natural language processing, computer vision, structured data and neural graph learning, we lay the foundations for the multimodal sections to follow. We then discuss recent multimodal learning literature covering visual, audio and language streams, and explore case studies focusing on tasks which require fine-grained understanding of visual and linguistic semantics question answering, veracity and hatred classification. Finally, we introduce a new dataset for recognizing multimodal entailment, exploring it in a hands-on collaborative section. Overall, this tutorial gives an overview of multimodal learning, introduces a multimodal entailment dataset, and encourages future research in the topic.","lang":"eng"}],"_id":"10367","has_accepted_license":"1","type":"conference","language":[{"iso":"eng"}],"month":"08","page":"29-30","ddc":["000"],"date_created":"2021-11-28T23:01:30Z","citation":{"mla":"Ilharco, Cesar, et al. “Recognizing Multimodal Entailment.” 59th Annual Meeting of the Association for Computational Linguistics and the 11th International Joint Conference on Natural Language Processing, Tutorial Abstracts, Association for Computational Linguistics, 2021, pp. 29–30, doi:10.18653/v1/2021.acl-tutorials.6.","short":"C.

Lexicographic ranking functions provide a sound and practical approach for termination of non-probabilistic programs, and their extension to probabilistic programs is achieved via lexicographic ranking supermartingales (LexRSMs). However, LexRSMs introduced in the previous work have a limitation that impedes their automation: all of their components have to be non-negative in all reachable states. This might result in LexRSM not existing even for simple terminating programs. Our contributions are twofold: First, we introduce a generalization of LexRSMs which allows for some components to be negative. This standard feature of non-probabilistic termination proofs was hitherto not known to be sound in the probabilistic setting, as the soundness proof requires a careful analysis of the underlying stochastic process. Second, we present polynomial-time algorithms using our generalized LexRSMs for proving a.s. termination in broad classes of linear-arithmetic programs."}],"type":"conference","external_id":{"isi":["000758218600033"],"arxiv":["2108.02188"]},"language":[{"iso":"eng"}],"isi":1,"month":"11","acknowledgement":"This research was partially supported by the ERC CoG 863818 (ForM-SMArt), the Czech Science Foundation grant No. GJ19-15134Y, and the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie Grant Agreement No. 665385.","status":"public","scopus_import":"1","conference":{"name":"FM: Formal Methods","end_date":"2021-11-26","location":"Virtual","start_date":"2021-11-20"}},{"quality_controlled":"1","project":[{"name":"Teaching Old Crypto New Tricks","call_identifier":"H2020","_id":"258AA5B2-B435-11E9-9278-68D0E5697425","grant_number":"682815"}],"doi":"10.1007/978-3-030-92075-3_12","title":"Reverse firewalls for adaptively secure MPC without setup","department":[{"_id":"KrPi"}],"publication_status":"published","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","year":"2021","date_published":"2021-12-01T00:00:00Z","author":[{"first_name":"Suvradip","full_name":"Chakraborty, Suvradip","last_name":"Chakraborty","id":"B9CD0494-D033-11E9-B219-A439E6697425"},{"first_name":"Chaya","full_name":"Ganesh, Chaya","last_name":"Ganesh"},{"last_name":"Pancholi","full_name":"Pancholi, Mahak","first_name":"Mahak"},{"first_name":"Pratik","full_name":"Sarkar, Pratik","last_name":"Sarkar"}],"day":"01","article_processing_charge":"No","type":"conference","abstract":[{"lang":"eng","text":"We study Multi-party computation (MPC) in the setting of subversion, where the adversary tampers with the machines of honest parties. Our goal is to construct actively secure MPC protocols where parties are corrupted adaptively by an adversary (as in the standard adaptive security setting), and in addition, honest parties’ machines are compromised.\r\nThe idea of reverse firewalls (RF) was introduced at EUROCRYPT’15 by Mironov and Stephens-Davidowitz as an approach to protecting protocols against corruption of honest parties’ devices. Intuitively, an RF for a party P is an external entity that sits between P and the outside world and whose scope is to sanitize P ’s incoming and outgoing messages in the face of subversion of their computer. Mironov and Stephens-Davidowitz constructed a protocol for passively-secure two-party computation. At CRYPTO’20, Chakraborty, Dziembowski and Nielsen constructed a protocol for secure computation with firewalls that improved on this result, both by extending it to multi-party computation protocol, and considering active security in the presence of static corruptions. In this paper, we initiate the study of RF for MPC in the adaptive setting. We put forward a definition for adaptively secure MPC in the reverse firewall setting, explore relationships among the security notions, and then construct reverse firewalls for MPC in this stronger setting of adaptive security. We also resolve the open question of Chakraborty, Dziembowski and Nielsen by removing the need for a trusted setup in constructing RF for MPC. Towards this end, we construct reverse firewalls for adaptively secure augmented coin tossing and adaptively secure zero-knowledge protocols and obtain a constant round adaptively secure MPC protocol in the reverse firewall setting without setup. Along the way, we propose a new multi-party adaptively secure coin tossing protocol in the plain model, that is of independent interest."}],"_id":"10609","month":"12","isi":1,"external_id":{"isi":["000927876200012"]},"language":[{"iso":"eng"}],"status":"public","conference":{"name":"ASIACRYPT: International Conference on Cryptology in Asia","start_date":"2021-12-06","location":"Virtual, Singapore","end_date":"2021-12-10"},"scopus_import":"1","date_updated":"2025-04-14T07:22:06Z","oa":1,"alternative_title":["LNCS"],"oa_version":"Preprint","date_created":"2022-01-09T23:01:27Z","intvolume":" 13091","citation":{"short":"S.

Bluefors and Zurich Instruments have supported the growth of this field from the 2010s onwards by providing well-engineered and reliable measurement infrastructure [2]– [6]. Having a long and stable qubit lifetime is a critical system property. Therefore, considerable effort has already gone into measuring qubit energy-relaxation timescales and their fluctuations, see Refs. [7]–[10] among others. Accurately extracting the statistics of a quantum device requires users to perform time consuming measurements. One measurement challenge is that the detection of the state-dependent\r\nresponse of a superconducting resonator due to a dispersively-coupled qubit requires an inherently low signal level. Consequently, measurements must be performed using a microwave probe that contains only a few microwave photons. Improving the signal-to-noise ratio (SNR) by using near-quantum limited parametric amplifiers as well as the use of optimized signal processing enabled by efficient room temperature instrumentation help to reduce measurement time. An empirical observation for fixed frequency transmons from recent literature is that as the energy-relaxation time 𝑇𝑇1 increases, so do its natural temporal fluctuations [7], [10]. This necessitates many repeated measurements to understand the statistics (see for example, Ref. [10]). In addition, as state-of-the-art qubits increase in lifetime, longer\r\nmeasurement times are expected to obtain accurate statistics. As described below, the scaling of the widths of the qubit energy-relaxation distributions also reveal clues about the origin of the energy-relaxation.","lang":"eng"}]},{"publication_identifier":{"eissn":["2329-0501"]},"volume":23,"article_type":"original","date_created":"2022-01-23T23:01:28Z","citation":{"short":"M.E.

Transduction of microglia is mostly excluded from this strategy, likely due to the cells’ heterogeneous state upon environmental changes, which makes AAV design challenging. Here, we established the retina as a model system for microglial AAV validation and optimization. First, we show that AAV2/6 transduced microglia in both synaptic layers, where layer preference corresponds to the intravitreal or subretinal delivery method. Surprisingly, we observed significantly enhanced microglial transduction during photoreceptor degeneration. Thus, we modified the AAV6 capsid to reduce heparin binding by introducing four point mutations (K531E, R576Q, K493S, and K459S), resulting in increased microglial transduction in the outer plexiform layer. Finally, to improve microglial-specific transduction, we validated a Cre-dependent transgene delivery cassette for use in combination with the Cx3cr1CreERT2 mouse line. Together, our results provide a foundation for future studies optimizing AAV-mediated microglia transduction and highlight that environmental conditions influence microglial transduction efficiency.\r\n"}],"_id":"10655","has_accepted_license":"1","corr_author":"1","article_processing_charge":"Yes","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"},"date_published":"2021-12-10T00:00:00Z","author":[{"last_name":"Maes","id":"3838F452-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9642-1085","first_name":"Margaret E","full_name":"Maes, Margaret E"},{"last_name":"Wögenstein","full_name":"Wögenstein, Gabriele M.","first_name":"Gabriele M."},{"last_name":"Colombo","orcid":"0000-0001-9434-8902","id":"3483CF6C-F248-11E8-B48F-1D18A9856A87","first_name":"Gloria","full_name":"Colombo, Gloria"},{"first_name":"Raquel","full_name":"Casado Polanco, Raquel","last_name":"Casado Polanco","id":"15240fc1-dbcd-11ea-9d1d-ac5a786425fd","orcid":"0000-0001-8293-4568"},{"full_name":"Siegert, Sandra","first_name":"Sandra","orcid":"0000-0001-8635-0877","id":"36ACD32E-F248-11E8-B48F-1D18A9856A87","last_name":"Siegert"}],"day":"10","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","year":"2021","publication_status":"published","file":[{"date_created":"2022-01-24T07:43:09Z","relation":"main_file","checksum":"77dc540e8011c5475031bdf6ccef20a6","content_type":"application/pdf","success":1,"file_size":4794147,"date_updated":"2022-01-24T07:43:09Z","creator":"cchlebak","file_id":"10657","access_level":"open_access","file_name":"2021_MolTherMethodsClinDev_Maes.pdf"}],"title":"Optimizing AAV2/6 microglial targeting identified enhanced efficiency in the photoreceptor degenerative environment","department":[{"_id":"SaSi"},{"_id":"SiHi"}],"quality_controlled":"1","project":[{"_id":"25D4A630-B435-11E9-9278-68D0E5697425","grant_number":"715571","name":"Microglia action towards neuronal circuit formation and function in health and disease","call_identifier":"H2020"}],"acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"},{"_id":"PreCl"}],"doi":"10.1016/j.omtm.2021.09.006"},{"quality_controlled":"1","project":[{"name":"Formal methods for the design and analysis of complex systems","call_identifier":"FWF","_id":"25F42A32-B435-11E9-9278-68D0E5697425","grant_number":"Z211"}],"doi":"10.34727/2021/isbn.978-3-85448-046-4_23","editor":[{"first_name":"Piskac","full_name":"Ruzica, Piskac","last_name":"Ruzica"},{"last_name":"Whalen","first_name":"Michael W.","full_name":"Whalen, Michael W."}],"title":"The Civl verifier","department":[{"_id":"ToHe"}],"file":[{"file_size":390555,"success":1,"checksum":"35438ac9f9750340b7f8ae4ae3220d9f","content_type":"application/pdf","date_created":"2022-01-26T08:04:29Z","relation":"main_file","file_id":"10689","access_level":"open_access","file_name":"2021_FCAD2021_Kragl.pdf","creator":"cchlebak","date_updated":"2022-01-26T08:04:29Z"}],"publication_status":"published","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","year":"2021","date_published":"2021-10-01T00:00:00Z","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"},"author":[{"first_name":"Bernhard","full_name":"Kragl, Bernhard","last_name":"Kragl","id":"320FC952-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7745-9117"},{"last_name":"Qadeer","full_name":"Qadeer, Shaz","first_name":"Shaz"}],"day":"01","corr_author":"1","article_processing_charge":"No","type":"conference","abstract":[{"text":"Civl is a static verifier for concurrent programs designed around the conceptual framework of layered refinement,\r\nwhich views the task of verifying a program as a sequence of program simplification steps each justified by its own invariant.

A significant fraction of these could be powered by coalescing massive black hole (MBH) binaries, since many quasars are believed to be triggered by mergers. We show that under plausible assumptions about the luminosity functions, lifetimes, and binary fractions of quasars, we expect the full LSST quasar catalogue to contain between 20 and 100 million compact MBH binaries with masses M = 105–9M⊙, redshifts z = 0–6, and orbital periods P = 1–70 d. Their light-curves are expected to be distinctly periodic, which can be confidently distinguished from stochastic red-noise variability, because LSST will cover dozens, or even hundreds of cycles. A very small subset of 10–150 ultracompact (P ≲ 1 d) binary quasars among these will, over ∼5–15 yr, evolve into the mHz gravitational-wave frequency band and can be detected by LISA. They can therefore be regarded as ‘LISA verification binaries’, analogous to short-period Galactic compact-object binaries.

Based on the performance of LISA Pathfinder, it is now expected that LISA will have a duty cycle of ≈0.75 , which would reduce the effective span of usable data to 3 years. This paper reports the results of a study by the LISA Science Group, which was charged with assessing the additional science return of increasing the mission lifetime. We explore various observational scenarios to assess the impact of mission duration on the main science objectives of the mission. We find that the science investigations most affected by mission duration concern the search for seed black holes at cosmic dawn, as well as the study of stellar-origin black holes and of their formation channels via multi-band and multi-messenger observations. We conclude that an extension to 6 years of mission operations is recommended."}],"_id":"17593","month":"12","language":[{"iso":"eng"}],"article_number":"3","date_published":"2021-12-27T00:00:00Z","author":[{"first_name":"Pau","full_name":"Amaro Seoane, Pau","last_name":"Amaro Seoane"},{"last_name":"Arca Sedda","first_name":"Manuel","full_name":"Arca Sedda, Manuel"},{"full_name":"Babak, Stanislav","first_name":"Stanislav","last_name":"Babak"},{"first_name":"Christopher P.

Several scenarios have been proposed to date to explain massive BH formation, from the low-mass seed BH remnants of the first generation of stars to the massive seed BHs resulting from the rapid collapse of massive gas clouds. However, the plausibility of some of these scenarios to occur within the progenitors of high-z quasars has not yet been thoroughly explored. In this work, we investigate, by combining dark-matter only N-body simulations with a semi-analytic framework, whether the conditions for the formation of massive seed BHs from synchronised atomic-cooling halo pairs and/or dynamically-heated mini-haloes are fulfilled in the overdense regions where the progenitors of a typical high-redshift quasar host form and evolve. Our analysis shows that the peculiar conditions in such regions, i.e. strong halo clustering and high star formation rates, are crucial to produce a non-negligible number of massive seed BH host candidates: we find ≈1400 dynamically heated metal-free mini-haloes, including one of these which evolves to a synchronised pair and ends up in the massive quasar-host halo by z=6. This demonstrates that the progenitors of high-redshift quasar host haloes can harbour early massive seed BHs. Our results further suggest that multiple massive seed BHs may form in or near the quasar host's progenitors, potentially merging at lower redshifts and yielding gravitational wave events.","lang":"eng"}],"_id":"17610","type":"journal_article","article_type":"original","main_file_link":[{"url":" https://doi.org/10.48550/arXiv.2102.05051","open_access":"1"}],"volume":503,"publication_identifier":{"issn":["0035-8711","1365-2966"]},"page":"5046-5060","date_created":"2024-09-05T13:22:23Z","citation":{"short":"A.

A common approach is to design molecular backbones where destructive quantum interference (QI) between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) produces a nonlinear energy-dependent tunnelling probability near the electrode Fermi energy (EF)5,6,7,8. However, tuning such systems is not straightforward, as aligning the frontier orbitals to EF is hard to control9. Here, we instead create a molecular system where constructive QI between the HOMO and LUMO is suppressed and destructive QI between the HOMO and strongly coupled occupied orbitals of opposite phase is enhanced. We use a series of fluorene oligomers containing a central benzothiadiazole10 unit to demonstrate that this strategy can be used to create highly nonlinear single-molecule circuits.

In particular, ultracold atoms in optical lattices provide a highly controllable and adaptable platform to study such new types of quantum matter. However, finding a clear route to realize non-Abelian quantum Hall states in these systems remains challenging. Here we use the density-matrix renormalization-group (DMRG) method to study the Hofstadter-Bose-Hubbard model at filling factor 𝜈=1 and find strong indications that at 𝛼=1/6 magnetic flux quanta per plaquette the ground state is a lattice analog of the continuum non-Abelian Pfaffian. We study the on-site correlations of the ground state, which indicate its paired nature at 𝜈=1, and find an incompressible state characterized by a charge gap in the bulk. We argue that the emergence of a charge density wave on thin cylinders and the behavior of the two- and three-particle correlation functions at short distances provide evidence for the state being closely related to the continuum Pfaffian. The signatures discussed in this letter are accessible in current cold atom experiments and we show that the Pfaffian-like state is readily realizable in few-body systems using adiabatic preparation schemes.","lang":"eng"}],"type":"journal_article","article_number":"L161101","language":[{"iso":"eng"}],"external_id":{"arxiv":["2011.02477"]},"month":"04","status":"public","scopus_import":"1","issue":"16"},{"oa":1,"date_updated":"2026-06-18T19:28:41Z","related_material":{"record":[{"id":"6933","status":"public","relation":"earlier_version"}]},"oa_version":"Published Version","page":"463-487","intvolume":" 34","citation":{"short":"K.

The idea behind expansion microscopy is to embed the biological sample in a swellable gel, and then to expand it isotropically, thereby increasing the distance between the fluorophores. This approach breaks the diffraction barrier by simply separating the emission point-spread-functions of the fluorophores. The resolution attainable in expansion microscopy is thus directly dependent on the separation that can be achieved, i.e. on the expansion factor. The original implementation of the technique achieved an expansion factor of fourfold, for a resolution of 70–80 nm. The subsequently developed X10 method achieves an expansion factor of 10-fold, for a resolution of 25–30 nm. This technique can be implemented with minimal technical requirements on any standard fluorescence microscope, and is more easily applied for multi-color imaging than either deterministic or stochastic super-resolution approaches. This renders X10 expansion microscopy a highly promising tool for new biological discoveries, as discussed here, and as demonstrated by several recent applications."}],"type":"book_chapter","external_id":{"pmid":["33478696"]},"language":[{"iso":"eng"}],"month":"01","status":"public","pmid":1,"scopus_import":"1"},{"volume":22,"publication_identifier":{"eissn":["1471-0048"],"issn":["1471-003X"]},"article_type":"letter_note","date_created":"2020-11-15T23:01:18Z","intvolume":" 22","citation":{"ama":"Bozelos P, Vogels TP.

However, during the discovery of cost-efficient routes for the transaction, critical information may be revealed about the transacting entities. This paper initiates the study of privacy-preserving route discovery mechanisms for payment channel networks. In particular, we present LightPIR, an approach which allows a client to learn the shortest (or cheapest in terms of fees) path between two nodes without revealing any information about the endpoints of the transaction to the servers. The two main observations which allow for an efficient solution in LightPIR are that: (1) surprisingly, hub labelling algorithms – which were developed to preprocess “street network like” graphs so one can later efficiently compute shortest paths – also perform well for the graphs underlying payment channel networks, and that (2) hub labelling algorithms can be conveniently combined with private information retrieval. LightPIR relies on a simple hub labeling heuristic on top of existing hub labeling algorithms which leverages the specific topological features of cryptocurrency networks to further minimize storage and bandwidth overheads. In a case study considering the Lightning network, we show that our approach is an order of magnitude more efficient compared to a privacy-preserving baseline based on using private information retrieval on a database that stores all pairs shortest paths."}]}]
