Most existing methods for estimating the face reflectance from a monocular image assume faces to be diffuse with very few approaches adding a specular component. This still leaves out important perceptual aspects of reflectance as higher-order global illumination effects and self-shadowing are not modeled. We present a new neural representation for face reflectance where we can estimate all components of the reflectance responsible for the final appearance from a single monocular image. Instead of modeling each component of the reflectance separately using parametric models, our neural representation allows us to generate a basis set of faces in a geometric deformation-invariant space, parameterized by the input light direction, viewpoint and face geometry. We learn to reconstruct this reflectance field of a face just from a monocular image, which can be used to render the face from any viewpoint in any light condition. Our method is trained on a light-stage training dataset, which captures 300 people illuminated with 150 light conditions from 8 viewpoints. We show that our method outperforms existing monocular reflectance reconstruction methods, in terms of photorealism due to better capturing of physical premitives, such as sub-surface scattering, specularities, self-shadows and other higher-order effects."}],"publication_status":"published","publication_identifier":{"isbn":["978-166544509-2"],"issn":["1063-6919"]},"file_date_updated":"2021-08-24T06:02:15Z","arxiv":1,"month":"09","department":[{"_id":"BeBi"}],"file":[{"file_id":"9958","date_updated":"2021-08-24T06:02:15Z","creator":"bbickel","file_size":4746649,"date_created":"2021-08-24T06:02:15Z","checksum":"961db0bde76dd87cf833930080bb9f38","relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_name":"R_Monocular_Reconstruction_of_Neural_Face_Reflectance_Fields_CVPR_2021_paper[1].pdf"}],"oa":1,"language":[{"iso":"eng"}],"citation":{"mla":"B R, Mallikarjun, et al. “Monocular Reconstruction of Neural Face Reflectance Fields.” <i>Proceedings of the IEEE Computer Society Conference on Computer Vision and Pattern Recognition</i>, IEEE, 2021, pp. 4791–800, doi:<a href=\"https://doi.org/10.1109/CVPR46437.2021.00476\">10.1109/CVPR46437.2021.00476</a>.","apa":"B R, M., Tewari, A., Oh, T.-H., Weyrich, T., Bickel, B., Seidel, H.-P., … Theobalt, C.

We analyze a simple, related model where these phenomena originate from spatiotemporal ordering in an effective Floquet unitary, corresponding to discrete time-crystalline behavior in a prethermal regime. Unlike conventional discrete time crystals, the subharmonic response exists only for Néel-like initial states, associated with quantum scars. We predict robustness to perturbations and identify emergent timescales that could be observed in future experiments.

We investigate and compare the scaling of Thouless energy across the many-body localization (MBL) transition in a Floquet model. We use a combination of methods that are reliable on the ergodic side of the transition (e.g., spectral form factor) and methods that work on the MBL side (e.g., typical matrix elements of local operators) to obtain a complete picture of the Thouless energy behavior across the transition. On the ergodic side, Thouless energy decreases slowly with the system size, while at the transition it becomes comparable to the level spacing. Different probes yield consistent estimates of Thouless energy in their overlapping regime of applicability, giving the location of the transition point nearly free of finite-size drift. This work establishes a connection between different definitions of Thouless energy in a many-body setting and yields insights into the MBL transition in Floquet systems."}],"publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"publication_status":"published","year":"2021","isi":1,"external_id":{"arxiv":["2012.15676"],"isi":["000689734500009"]},"project":[{"_id":"23841C26-32DE-11EA-91FC-C7463DDC885E","call_identifier":"H2020","name":"Non-Ergodic Quantum Matter: Universality, Dynamics and Control","grant_number":"850899"}],"status":"public","publication":"Physical Review B","ec_funded":1,"acknowledgement":"We thank S.

The cerebral cortex is the largest site of neural integration in the central nervous system. Concerted radial migration of newly born cortical projection neurons, from their birthplace to their final position, is a key step in the assembly of the cerebral cortex. The cellular and molecular mechanisms regulating radial neuronal migration in vivo are however still unclear. Recent evidence suggests that distinct signaling cues act cell-autonomously but differentially at certain steps during the overall migration process. Moreover, functional analysis of genetic mosaics (mutant neurons present in wild-type/heterozygote environment) using the MADM (Mosaic Analysis with Double Markers) analyses in comparison to global knockout also indicate a significant degree of non-cell-autonomous and/or community effects in the control of cortical neuron migration. The interactions of cell-intrinsic (cell-autonomous) and cell-extrinsic (non-cell-autonomous) components are largely unknown. In part of this thesis work we established a MADM-based experimental strategy for the quantitative analysis of cell-autonomous gene function versus non-cell-autonomous and/or community effects. The direct comparison of mutant neurons from the genetic mosaic (cell-autonomous) to mutant neurons in the conditional and/or global knockout (cell-autonomous + non-cell-autonomous) allows to quantitatively analyze non-cell-autonomous effects. Such analysis enable the high-resolution analysis of projection neuron migration dynamics in distinct environments with concomitant isolation of genomic and proteomic profiles. Using these experimental paradigms and in combination with computational modeling we show and characterize the nature of non-cell-autonomous effects to coordinate radial neuron migration. Furthermore, this thesis discusses recent developments in neurodevelopment with focus on neuronal polarization and non-cell-autonomous mechanisms in neuronal migration.","lang":"eng"}],"department":[{"_id":"GradSch"},{"_id":"SiHi"}],"file":[{"file_id":"9971","embargo_to":"open_access","date_created":"2021-08-30T09:17:39Z","file_size":10629190,"creator":"ahansen","date_updated":"2022-09-03T22:30:04Z","relation":"source_file","checksum":"66b56f5b988b233dc66a4f4b4fb2cdfe","file_name":"Thesis_Hansen.docx","access_level":"closed","content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document"},{"file_size":13457469,"date_created":"2021-08-30T09:29:44Z","creator":"ahansen","embargo":"2022-09-02","date_updated":"2022-09-03T22:30:04Z","file_id":"9972","file_name":"Thesis_Hansen_PDFA-1a.pdf","content_type":"application/pdf","access_level":"open_access","relation":"main_file","checksum":"204fa40321a1c6289b68c473634c4bf3"}],"supervisor":[{"id":"37B36620-F248-11E8-B48F-1D18A9856A87","full_name":"Hippenmeyer, Simon","last_name":"Hippenmeyer","orcid":"0000-0003-2279-1061","first_name":"Simon"}],"month":"09","citation":{"ama":"Hansen AH.

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."}],"publication_status":"published","publication_identifier":{"isbn":["978-1-6654-4501-6"],"eisbn":["978-3-9031-7639-3"],"eissn":["1861-2288"]},"oa_version":"Submitted Version","title":"LightPIR: Privacy-preserving route discovery for payment channel networks","day":"21","scopus_import":"1","author":[{"orcid":"0000-0002-9139-1654","first_name":"Krzysztof Z","last_name":"Pietrzak","id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","full_name":"Pietrzak, Krzysztof Z"},{"first_name":"Iosif","full_name":"Salem, Iosif","last_name":"Salem"},{"first_name":"Stefan","last_name":"Schmid","full_name":"Schmid, Stefan"},{"first_name":"Michelle X","id":"2D82B818-F248-11E8-B48F-1D18A9856A87","full_name":"Yeo, Michelle X","last_name":"Yeo"}],"date_created":"2021-08-29T22:01:16Z","language":[{"iso":"eng"}],"oa":1,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"ista":"Pietrzak KZ, Salem I, Schmid S, Yeo MX. 2021.

For mediators to work efficiently they need to oxidize the solid with fast kinetics yet the lowest possible overpotential. Here, we found that when the redox potentials of mediators are tuned via, e.g., Li + concentration in the electrolyte, they exhibit distinct threshold potentials, where the kinetics accelerate several-fold within a range as small as 10 mV. This phenomenon is independent of types of mediators and electrolyte. The acceleration originates from the overpotentials required to activate fast Li + /e – extraction and the following chemical step at specific abundant surface facets. Efficient redox catalysis at insulating solids requires therefore carefully considering the surface conditions of the storage materials and electrolyte-dependent redox potentials, which may be tuned by salt concentrations or solvents."}],"has_accepted_license":"1","file_date_updated":"2021-08-31T14:02:19Z","publication_identifier":{"eissn":["2693-5015"]},"publication_status":"submitted","title":"Sharp kinetic acceleration potentials during mediated redox catalysis of insulators","oa_version":"Preprint","day":"18","author":[{"last_name":"Cao","full_name":"Cao, Deqing","first_name":"Deqing"},{"first_name":"Xiaoxiao","full_name":"Shen, Xiaoxiao","last_name":"Shen"},{"first_name":"Aiping","full_name":"Wang, Aiping","last_name":"Wang"},{"first_name":"Fengjiao","last_name":"Yu","full_name":"Yu, Fengjiao"},{"first_name":"Yuping","full_name":"Wu, Yuping","last_name":"Wu"},{"first_name":"Siqi","full_name":"Shi, Siqi","last_name":"Shi"},{"orcid":"0000-0003-2902-5319","first_name":"Stefan Alexander","last_name":"Freunberger","id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","full_name":"Freunberger, Stefan Alexander"},{"full_name":"Chen, Yuhui","last_name":"Chen","first_name":"Yuhui"}],"date_created":"2021-08-31T12:54:16Z","language":[{"iso":"eng"}],"oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ama":"Cao D, Shen X, Wang A, et al.

Typically Li2S formation is explained by direct electroreduction of a PS to Li2S; however, this is not consistent with the size of the insulating Li2S deposits. Here, we use in situ small and wide angle X-ray scattering (SAXS/WAXS) to track the growth and dissolution of crystalline and amorphous deposits from atomic to sub-micron scales during charge and discharge. Stochastic modelling based on the SAXS data allows quantification of the chemical phase evolution during discharge and charge. We show that Li2S deposits predominantly via disproportionation of transient, solid Li2S2 to form primary Li2S crystallites and solid Li2S4 particles. We further demonstrate that this process happens in reverse during charge. These findings show that the discharge capacity and rate capability in Li-S battery cathodes are therefore limited by mass transport through the increasingly tortuous network of Li2S / Li2S4 / carbon pores rather than electron transport through a passivating surface film."}],"page":"21","keyword":["Li2S","Lithium Sulphur Batteries","SAXS","WAXS"],"department":[{"_id":"StFr"}],"month":"08","year":"2021","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","acknowledgement":"This project has received funding from the European Union’s Horizon 2020 research and innovation program under the Marie Skłodowska-Curie grant NanoEvolution, grant agreement No 894042.

Although a number of promising numerical methods exist, they often have limited applicability due to the growth of entanglement or the presence of the so-called sign problem. In this work, we develop an importance sampling scheme for the simulation of quantum spin dynamics, building on a recent approach mapping quantum spin systems to classical stochastic processes. The importance sampling scheme is based on identifying the classical trajectory that yields the largest contribution to a given quantum observable. An exact transformation is then carried out to preferentially sample trajectories that are close to the dominant one. We demonstrate that this approach is capable of reducing the temporal growth of fluctuations in the stochastic quantities, thus extending the range of accessible times and system sizes compared to direct sampling. We discuss advantages and limitations of the proposed approach, outlining directions\r\nfor further developments."}],"intvolume":"        11","has_accepted_license":"1","article_number":"048","file":[{"file_id":"9984","date_created":"2021-09-02T14:05:43Z","file_size":373833,"date_updated":"2021-09-02T14:05:43Z","creator":"cchlebak","relation":"main_file","checksum":"e4ec69d893e31811efc6093cb6ea8eb7","file_name":"2021_SciPostPhys_DeNicola.pdf","success":1,"content_type":"application/pdf","access_level":"open_access"}],"department":[{"_id":"MaSe"}],"month":"09","arxiv":1,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","issue":"3","citation":{"ista":"De Nicola S. 2021.

Changes in AMPAR localisation can enact synaptic plasticity, allowing long-term information storage, and is therefore tightly controlled. Multiple mechanisms regulating AMPAR synaptic anchoring have been described, but with limited coherence or comparison between reports, our understanding of this process is unclear. Here, combining synaptic recordings from mouse hippocampal slices and super-resolution imaging in dissociated cultures, we compare the contributions of three AMPAR interaction domains controlling transmission at hippocampal CA1 synapses. We show that the AMPAR C-termini play only a modulatory role, whereas the extracellular N-terminal domain (NTD) and PDZ interactions of the auxiliary subunit TARP γ8 are both crucial, and each is sufficient to maintain transmission. Our data support a model in which γ8 accumulates AMPARs at the postsynaptic density, where the NTD further tunes their positioning. This interplay between cytosolic (TARP γ8) and synaptic cleft (NTD) interactions provides versatility to regulate synaptic transmission and plasticity."}],"volume":12,"article_type":"original","date_created":"2021-09-05T22:01:23Z","author":[{"orcid":"0000-0002-8698-3823","first_name":"Jake","id":"63836096-4690-11EA-BD4E-32803DDC885E","full_name":"Watson, Jake","last_name":"Watson"},{"last_name":"Pinggera","full_name":"Pinggera, Alexandra","first_name":"Alexandra"},{"first_name":"Hinze","last_name":"Ho","full_name":"Ho, Hinze"},{"first_name":"Ingo H.","full_name":"Greger, Ingo H.","last_name":"Greger"}],"scopus_import":"1","day":"23","title":"AMPA receptor anchoring at CA1 synapses is determined by N-terminal domain and TARP γ8 interactions","oa_version":"Published Version","issue":"1","citation":{"ista":"Watson J, Pinggera A, Ho H, Greger IH. 2021.

As scheduling non-determinism creates exponentially large spaces of thread interleavings, SMC attempts to partition this space into equivalence classes and explore only a few representatives from each class. The efficiency of this approach depends on two factors: (a) the coarseness of the partitioning, and (b) the time to generate representatives in each class. For this reason, the search for coarse partitionings that are efficiently explorable is an active research challenge. In this work we present   RVF-SMC , a new SMC algorithm that uses a novel reads-value-from (RVF) partitioning. Intuitively, two interleavings are deemed equivalent if they agree on the value obtained in each read event, and read events induce consistent causal orderings between them. The RVF partitioning is provably coarser than recent approaches based on Mazurkiewicz and “reads-from” partitionings. Our experimental evaluation reveals that RVF is quite often a very effective equivalence, as the underlying partitioning is exponentially coarser than other approaches. Moreover,   RVF-SMC  generates representatives very efficiently, as the reduction in the partitioning is often met with significant speed-ups in the model checking task."}],"publication_identifier":{"eissn":["1611-3349"],"eisbn":["978-3-030-81685-8"],"isbn":["978-3-030-81684-1"],"issn":["0302-9743"]},"publication_status":"published","file_date_updated":"2022-05-13T07:00:20Z"},{"day":"13","author":[{"last_name":"Hörmayer","id":"2EEE7A2A-F248-11E8-B48F-1D18A9856A87","full_name":"Hörmayer, Lukas","first_name":"Lukas","orcid":"0000-0001-8295-2926"}],"title":"Wound healing in the Arabidopsis root meristem","oa_version":"Published Version","date_created":"2021-09-09T07:37:20Z","has_accepted_license":"1","acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"}],"tmp":{"image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)"},"abstract":[{"lang":"eng","text":"Blood – this is what animals use to heal wounds fast and efficient. Plants do not have blood circulation and their cells cannot move. However, plants have evolved remarkable capacities to regenerate tissues and organs preventing further damage. In my PhD research, I studied the wound healing in the Arabidopsis root. I used a UV laser to ablate single cells in the root tip and observed the consequent wound healing. Interestingly, the inner adjacent cells induced a\r\ndivision plane switch and subsequently adopted the cell type of the killed cell to replace it. We termed this form of wound healing “restorative divisions”. This initial observation triggered the questions of my PhD studies: How and why do cells orient their division planes, how do they feel the wound and why does this happen only in inner adjacent cells.\r\nFor answering these questions, I used a quite simple experimental setup: 5 day - old seedlings were stained with propidium iodide to visualize cell walls and dead cells; ablation was carried out using a special laser cutter and a confocal microscope. Adaptation of the novel vertical microscope system made it possible to observe wounds in real time. This revealed that restorative divisions occur at increased frequency compared to normal divisions. Additionally,\r\nthe major plant hormone auxin accumulates in wound adjacent cells and drives the expression of the wound-stress responsive transcription factor ERF115. Using this as a marker gene for wound responses, we found that an important part of wound signalling is the sensing of the collapse of the ablated cell. The collapse causes a radical pressure drop, which results in strong tissue deformations. These deformations manifest in an invasion of the now free spot specifically by the inner adjacent cells within seconds, probably because of higher pressure of the inner tissues. Long-term imaging revealed that those deformed cells continuously expand towards the wound hole and that this is crucial for the restorative division. These wound-expanding cells exhibit an abnormal, biphasic polarity of microtubule arrays\r\nbefore the division. Experiments inhibiting cell expansion suggest that it is the biphasic stretching that induces those MT arrays. Adapting the micromanipulator aspiration system from animal scientists at our institute confirmed the hypothesis that stretching influences microtubule stability. In conclusion, this shows that microtubules react to tissue deformation\r\nand this facilitates the observed division plane switch. This puts mechanical cues and tensions at the most prominent position for explaining the growth and wound healing properties of plants. Hence, it shines light onto the importance of understanding mechanical signal transduction.

This mechanism requires that individuals in a population observe and judge each other’s behaviors. Individuals with a good reputation are more likely to receive help from others. Previous work suggests that indirect reciprocity is only effective when all relevant information is reliable and publicly available. Otherwise, individuals may disagree on how to assess others, even if they all apply the same social norm. Such disagreements can lead to a breakdown of cooperation. Here we explore whether the predominantly studied ‘leading eight’ social norms of indirect reciprocity can be made more robust by equipping them with an element of generosity. To this end, we distinguish between two kinds of generosity. According to assessment generosity, individuals occasionally assign a good reputation to group members who would usually be regarded as bad. According to action generosity, individuals occasionally cooperate with group members with whom they would usually defect. Using individual-based simulations, we show that the two kinds of generosity have a very different effect on the resulting reputation dynamics. Assessment generosity tends to add to the overall noise and allows defectors to invade. In contrast, a limited amount of action generosity can be beneficial in a few cases. However, even when action generosity is beneficial, the respective simulations do not result in full cooperation. Our results suggest that while generosity can favor cooperation when individuals use the most simple strategies of reciprocity, it is disadvantageous when individuals use more complex social norms.","lang":"eng"}],"has_accepted_license":"1","article_number":"17443","file":[{"file_size":2424943,"date_created":"2021-09-13T10:31:21Z","date_updated":"2021-09-13T10:31:21Z","creator":"cchlebak","file_id":"10006","success":1,"file_name":"2021_ScientificReports_Schmid.pdf","access_level":"open_access","content_type":"application/pdf","relation":"main_file","checksum":"19df8816cf958b272b85841565c73182"}],"department":[{"_id":"GradSch"},{"_id":"KrCh"}],"month":"08","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","issue":"1","citation":{"ama":"Schmid L, Shati P, Hilbe C, Chatterjee K.

Here we uncovered a progenitor cell allocation mechanism that stems from an incomplete process of epithelial delamination that allows progenitors to coordinate their movement with adjacent extra-embryonic tissues. Progenitors of the zebrafish laterality organ originate from the surface epithelial enveloping layer by an apical constriction process of cell delamination. During this process, progenitors retain long-term apical contacts that enable the epithelial layer to pull a subset of progenitors along their way towards the vegetal pole. The remaining delaminated progenitors follow apically-attached progenitors’ movement by a co-attraction mechanism, avoiding sequestration by the adjacent endoderm, ensuring their fate and collective allocation at the differentiation site. Thus, we reveal that incomplete delamination serves as a cellular platform for coordinated tissue movements during development. Impact Statement: Incomplete delamination serves as a cellular platform for coordinated tissue movements during development, guiding newly formed progenitor cell groups to the differentiation site.","lang":"eng"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"intvolume":"        10","publication_status":"published","publication_identifier":{"eissn":["2050-084X"]},"file_date_updated":"2022-05-13T08:03:37Z","author":[{"last_name":"Pulgar","full_name":"Pulgar, Eduardo","first_name":"Eduardo"},{"last_name":"Schwayer","full_name":"Schwayer, Cornelia","id":"3436488C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5130-2226","first_name":"Cornelia"},{"first_name":"Néstor","full_name":"Guerrero, Néstor","last_name":"Guerrero"},{"full_name":"López, Loreto","last_name":"López","first_name":"Loreto"},{"last_name":"Márquez","full_name":"Márquez, Susana","first_name":"Susana"},{"full_name":"Härtel, Steffen","last_name":"Härtel","first_name":"Steffen"},{"full_name":"Soto, Rodrigo","last_name":"Soto","first_name":"Rodrigo"},{"first_name":"Carl Philipp","full_name":"Heisenberg, Carl Philipp","last_name":"Heisenberg"},{"full_name":"Concha, Miguel L.","last_name":"Concha","first_name":"Miguel L."}],"scopus_import":"1","day":"27","title":"Apical contacts stemming from incomplete delamination guide progenitor cell allocation through a dragging mechanism","oa_version":"Published Version","volume":10,"article_type":"original","date_created":"2021-09-12T22:01:23Z","oa":1,"language":[{"iso":"eng"}],"citation":{"mla":"Pulgar, Eduardo, et al. “Apical Contacts Stemming from Incomplete Delamination Guide Progenitor Cell Allocation through a Dragging Mechanism.” <i>ELife</i>, vol. 10, e66483, eLife Sciences Publications, 2021, doi:<a href=\"https://doi.org/10.7554/eLife.66483\">10.7554/eLife.66483</a>.","apa":"Pulgar, E., Schwayer, C., Guerrero, N., López, L., Márquez, S., Härtel, S., … Concha, M.

Inspired by the structure of the nervous system of the soil-worm, C. elegans, we introduce ordinary neural circuits (ONCs), defined as the model of biological neural circuits reparameterized for the control of alternative tasks. We first demonstrate that ONCs realize networks with higher maximum flow compared to arbitrary wired networks. We then learn instances of ONCs to control a series of robotic tasks, including the autonomous parking of a real-world rover robot. For reconfiguration of the purpose of the neural circuit, we adopt a search-based optimization algorithm. Ordinary neural circuits perform on par and, in some cases, significantly surpass the performance of contemporary deep learning models. ONC networks are compact, 77% sparser than their counterpart neural controllers, and their neural dynamics are fully interpretable at the cell-level.","lang":"eng"}],"tmp":{"image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/3.0/legalcode","short":"CC BY-NC-ND (3.0)"},"publication_identifier":{"issn":["2640-3498"]},"publication_status":"published","file_date_updated":"2022-01-26T11:08:51Z","author":[{"last_name":"Hasani","full_name":"Hasani, Ramin","first_name":"Ramin"},{"first_name":"Mathias","last_name":"Lechner","id":"3DC22916-F248-11E8-B48F-1D18A9856A87","full_name":"Lechner, Mathias"},{"first_name":"Alexander","full_name":"Amini, Alexander","last_name":"Amini"},{"first_name":"Daniela","last_name":"Rus","full_name":"Rus, Daniela"},{"first_name":"Radu","last_name":"Grosu","full_name":"Grosu, Radu"}],"scopus_import":"1","title":"A natural lottery ticket winner: Reinforcement learning with ordinary neural circuits","oa_version":"Published Version","date_created":"2022-01-25T15:50:34Z","oa":1,"language":[{"iso":"eng"}],"citation":{"ieee":"R.

We prove that the eigenvalue density on the scale slightly above the local eigenvalue spacing is asymptotically given by the free additive convolution of the laws of A and B as the dimension of the matrix increases. This implies optimal rigidity of the eigenvalues and optimal rate of convergence in Voiculescu's theorem. Our previous works [4], [5] established these results in the bulk spectrum, the current paper completely settles the problem at the spectral edges provided they have the typical square-root behavior. The key element of our proof is to compensate the deterioration of the stability of the subordination equations by sharp error estimates that properly account for the local density near the edge. Our results also hold if the Haar unitary matrix is replaced by the Haar orthogonal matrix.","lang":"eng"}]}]
