Weakly Supervised phrase-Grounding (WSG) deals with the task of using this data to learn to localize (or to ground) arbitrary text phrases in images without any additional annotations. However, most recent SotA methods for WSG assume an existence of a pre-trained object detector, relying on it to produce the ROIs for localization. In this work, we focus on the task of Detector-Free WSG (DF-WSG) to solve WSG without relying on a pre-trained detector. The key idea behind our proposed Grounding by Separation (GbS) method is synthesizing ‘text to image-regions’ associations by random alpha-blending of arbitrary image pairs and using the corresponding texts of the pair as conditions to recover the alpha map from the blended image via a segmentation network. At test time, this allows using the query phrase as a condition for a non-blended query image, thus interpreting the test image as a composition of a region corresponding to the phrase and the complement region. Our GbS shows an 8.5% accuracy improvement over previous DF-WSG SotA, for a range of benchmarks including Flickr30K, Visual Genome, and ReferIt, as well as a complementary improvement (above 7%) over the detector-based approaches for WSG."}],"date_updated":"2024-10-15T08:22:47Z","oa_version":"Preprint","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2024-10-08T13:02:34Z","OA_place":"repository","language":[{"iso":"eng"}],"external_id":{"arxiv":["2104.09829"]},"year":"2021","intvolume":"        15","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2104.09829","open_access":"1"}],"publisher":"Institute of Electrical and Electronics Engineers","arxiv":1,"doi":"10.1109/iccv48922.2021.00182","day":"20","OA_type":"green","scopus_import":"1"},{"scopus_import":"1","publisher":"Institute of Electrical and Electronics Engineers","arxiv":1,"doi":"10.1109/cvpr46437.2021.01176","OA_type":"green","day":"30","year":"2021","intvolume":"        38","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2012.04515","open_access":"1"}],"oa":1,"date_created":"2024-10-08T13:02:53Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","OA_place":"repository","language":[{"iso":"eng"}],"external_id":{"arxiv":["2012.04515"]},"abstract":[{"lang":"eng","text":"Mechanical image stabilization using actuated gimbals enables capturing long-exposure shots without suffering from blur due to camera motion. These devices, however, are often physically cumbersome and expensive, limiting their widespread use. In this work, we propose to digitally emulate a mechanically stabilized system from the input of a fast unstabilized camera. To exploit the trade-off between motion blur at long exposures and low SNR at short exposures, we train a CNN that estimates a sharp high-SNR image by aggregating a burst of noisy short-exposure frames, related by unknown motion. We further suggest learning the burst’s exposure times in an end-to-end manner, thus balancing the noise and blur across the frames. We demonstrate this method’s advantage over the traditional approach of deblurring a single image or denoising a fixed-exposure burst on both synthetic and real data."}],"volume":38,"month":"06","date_updated":"2024-10-15T08:42:37Z","oa_version":"Preprint","article_processing_charge":"No","citation":{"short":"O.

However, the usage of multiple receive channels lead to relative high costs and prevent the penetration of MIMOs in many areas such as the automotive industry. Over the last years, few studies concentrated on designing reduced measurement schemes and image reconstruction schemes for MIMO radars, however these problems have been so far addressed separately. On the other hand, recent works in optical computational imaging have demonstrated growing success of simultaneous learning-based design of the acquisition and reconstruction schemes, manifesting significant improvement in the reconstruction quality. Inspired by these successes, in this work, we propose to learn MIMO acquisition parameters in the form of receive (Rx) antenna elements locations jointly with an image neural-network based reconstruction. To this end, we propose an algorithm for training the combined acquisition-reconstruction pipeline end-to-end in a differentiable way. We demonstrate the significance of using our learned acquisition parameters with and without the neural-network reconstruction.

Fiber tractography takes advantage of diffusion Magnetic Resonance Imaging (dMRI) which allows measuring the apparent diffusivity of cerebral water along different spatial directions. Unfortunately, collecting such data comes at the price of reduced spatial resolution and substantially elevated acquisition times, which limits the clinical applicability of dMRI. This problem has been thus far addressed using two principal strategies. Most of the efforts have been extended towards improving the quality of signal estimation for any, yet fixed sampling scheme (defined through the choice of diffusion-encoding gradients). On the other hand, optimization over the sampling scheme has also proven to be effective. Inspired by the previous results, the present work consolidates the above strategies into a unified estimation framework, in which the optimization is carried out with respect to both estimation model and sampling design concurrently. The proposed solution offers substantial improvements in the quality of signal estimation as well as the accuracy of ensuing analysis by means of fiber tractography. While proving the optimality of the learned estimation models would probably need more extensive evaluation, we nevertheless claim that the learned sampling schemes can be of immediate use, offering a way to improve the dMRI analysis without the necessity of deploying the neural network used for their estimation.

However, the accurate acquisition of the depth profile is an expensive and challenging process. Here, we introduce a novel method that learns to recognize faces from stereo camera systems without the need to explicitly compute the facial surface or depth map. The raw face stereo images along with the location in the image from which the face is extracted allow the proposed CNN to improve the recognition task while avoiding the need to explicitly handle the geometric structure of the face. This way, we keep the simplicity and cost efficiency of identity authentication from a single image, while enjoying the benefits of geometric data without explicitly reconstructing it. We demonstrate that the suggested method outperforms both existing single-image and explicit depth based methods on largescale benchmarks, and even capable of recognize spoofing attacks. We also provide an ablation study that shows that the suggested method uses the face locations in the left and right images to encode informative features that improve the overall performance.","lang":"eng"}],"month":"01","date_updated":"2024-12-12T10:10:29Z","date_published":"2021-01-19T00:00:00Z","article_number":"9320359","author":[{"first_name":"Amir","last_name":"Livne","full_name":"Livne, Amir"},{"full_name":"Aviv, Ziv","last_name":"Aviv","first_name":"Ziv"},{"full_name":"Grofit, Shahaf","last_name":"Grofit","first_name":"Shahaf"},{"id":"58f3726e-7cba-11ef-ad8b-e6e8cb3904e6","first_name":"Alexander","last_name":"Bronstein","orcid":"0000-0001-9699-8730","full_name":"Bronstein, Alexander"},{"first_name":"Ron","last_name":"Kimmel","full_name":"Kimmel, Ron"}],"title":"Do we need depth in state-uf-the-art face authentication?","conference":{"start_date":"2020-11-25","location":"Fukuoka, Japan","end_date":"2020-11-28","name":"8th International Conference on 3D Vision"},"quality_controlled":"1","extern":"1","publication":"2020 International Conference on 3D Vision (3DV)","publication_status":"published","day":"19","arxiv":1,"doi":"10.1109/3dv50981.2020.00099","publisher":"IEEE","scopus_import":"1","language":[{"iso":"eng"}],"external_id":{"arxiv":["2003.10895"]},"date_created":"2024-10-08T13:04:02Z","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","oa":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2003.10895"}],"year":"2021"},{"date_published":"2021-11-01T00:00:00Z","author":[{"first_name":"Benjamin","full_name":"Harrop-Griffiths, Benjamin","last_name":"Harrop-Griffiths"},{"first_name":"Rowan","full_name":"Killip, Rowan","last_name":"Killip"},{"last_name":"Visan","full_name":"Visan, Monica","id":"056daca0-b8d1-11f0-964f-f91054abf8ca","first_name":"Monica"}],"title":"Microscopic conservation laws for integrable lattice models","publication":"Monatshefte für Mathematik","extern":"1","quality_controlled":"1","publication_status":"published","page":"477-504","_id":"22063","status":"public","article_processing_charge":"No","citation":{"short":"B.

Here, semiconductor–metal composites are produced by just blending nanoparticles of a sulfide semiconductor obtained in aqueous solution and at room temperature with a metallic Cu powder. The obtained blend is annealed in a reducing atmosphere and afterward consolidated into dense polycrystalline pellets through spark plasma sintering (SPS). We observe that, during the annealing process, the presence of metallic copper activates a partial reduction of the PbS, resulting in the formation of PbS–Pb–CuxS composites. The presence of metallic lead during the SPS process habilitates the liquid-phase sintering of the composite. Besides, by comparing the transport properties of PbS, the PbS–Pb–CuxS composites, and PbS–CuxS composites obtained by blending PbS and CuxS nanoparticles, we demonstrate that the presence of metallic lead decisively contributes to a strong increase of the charge carrier concentration through spillover of charge carriers enabled by the low work function of lead. The increase in charge carrier concentration translates into much higher electrical conductivities and moderately lower Seebeck coefficients. These properties translate into power factors up to 2.1 mW m–1 K–2 at ambient temperature, well above those of PbS and PbS + CuxS. Additionally, the presence of multiple phases in the final composite results in a notable decrease in the lattice thermal conductivity. Overall, the introduction of metallic copper in the initial blend results in a significant improvement of the thermoelectric performance of PbS, reaching a dimensionless thermoelectric figure of merit ZT = 1.1 at 750 K, which represents about a 400% increase over bare PbS. Besides, an average ZTave = 0.72 in the temperature range 320–773 K is demonstrated.","lang":"eng"}],"author":[{"first_name":"Mengyao","last_name":"Li","full_name":"Li, Mengyao"},{"last_name":"Liu","orcid":"0000-0001-7313-6740","full_name":"Liu, Yu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","first_name":"Yu"},{"full_name":"Zhang, Yu","last_name":"Zhang","first_name":"Yu"},{"first_name":"Xu","full_name":"Han, Xu","last_name":"Han"},{"last_name":"Xiao","full_name":"Xiao, Ke","first_name":"Ke"},{"full_name":"Nabahat, Mehran","last_name":"Nabahat","first_name":"Mehran"},{"first_name":"Jordi","last_name":"Arbiol","full_name":"Arbiol, Jordi"},{"first_name":"Jordi","last_name":"Llorca","full_name":"Llorca, Jordi"},{"full_name":"Ibáñez, Maria","last_name":"Ibáñez","orcid":"0000-0001-5013-2843","first_name":"Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Andreu","last_name":"Cabot","full_name":"Cabot, Andreu"}],"date_published":"2021-10-19T00:00:00Z","title":"PbS–Pb–CuxS composites for thermoelectric application","pmid":1,"quality_controlled":"1","publication":"ACS Applied Materials and Interfaces","page":"51373–51382","publication_status":"published","day":"19","doi":"10.1021/acsami.1c15609","publisher":"American Chemical Society","acknowledgement":"This work was supported by the European Regional Development Funds.

Its advantages include the abundance, low cost, and safety of its elements and a high performance at relatively elevated temperatures. However, stability issues limit its operation current and temperature, thus calling for the optimization of the material performance in the middle temperature range. Here, we present a synthetic protocol for large scale production of covellite CuS nanoparticles at ambient temperature and atmosphere, and using water as a solvent. The crystal phase and stoichiometry of the particles are afterward tuned through an annealing process at a moderate temperature under inert or reducing atmosphere. While annealing under argon results in Cu1.8S nanopowder with a rhombohedral crystal phase, annealing in an atmosphere containing hydrogen leads to tetragonal Cu1.96S. High temperature X-ray diffraction analysis shows the material annealed in argon to transform to the cubic phase at ca. 400 K, while the material annealed in the presence of hydrogen undergoes two phase transitions, first to hexagonal and then to the cubic structure. The annealing atmosphere, temperature, and time allow adjustment of the density of copper vacancies and thus tuning of the charge carrier concentration and material transport properties. In this direction, the material annealed under Ar is characterized by higher electrical conductivities but lower Seebeck coefficients than the material annealed in the presence of hydrogen. By optimizing the charge carrier concentration through the annealing time, Cu2–xS with record figures of merit in the middle temperature range, up to 1.41 at 710 K, is obtained. We finally demonstrate that this strategy, based on a low-cost and scalable solution synthesis process, is also suitable for the production of high performance Cu2–xS layers using high throughput and cost-effective printing technologies."}],"volume":15,"month":"03","keyword":["General Engineering","General Physics and Astronomy","General Materials Science"],"article_type":"original","author":[{"first_name":"Mengyao","last_name":"Li","full_name":"Li, Mengyao"},{"id":"2A70014E-F248-11E8-B48F-1D18A9856A87","first_name":"Yu","last_name":"Liu","orcid":"0000-0001-7313-6740","full_name":"Liu, Yu"},{"first_name":"Yu","full_name":"Zhang, Yu","last_name":"Zhang"},{"full_name":"Han, Xu","last_name":"Han","first_name":"Xu"},{"full_name":"Zhang, Ting","last_name":"Zhang","first_name":"Ting"},{"full_name":"Zuo, Yong","last_name":"Zuo","first_name":"Yong"},{"last_name":"Xie","full_name":"Xie, Chenyang","first_name":"Chenyang"},{"last_name":"Xiao","full_name":"Xiao, Ke","first_name":"Ke"},{"full_name":"Arbiol, Jordi","last_name":"Arbiol","first_name":"Jordi"},{"first_name":"Jordi","last_name":"Llorca","full_name":"Llorca, Jordi"},{"first_name":"Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","full_name":"Ibáñez, Maria","last_name":"Ibáñez","orcid":"0000-0001-5013-2843"},{"first_name":"Junfeng","full_name":"Liu, Junfeng","last_name":"Liu"},{"full_name":"Cabot, Andreu","last_name":"Cabot","first_name":"Andreu"}],"date_published":"2021-03-01T00:00:00Z","title":"Effect of the annealing atmosphere on crystal phase and thermoelectric properties of copper sulfide","publication":"ACS Nano","pmid":1,"quality_controlled":"1","page":"4967–4978","publication_status":"published"},{"date_updated":"2026-07-06T12:22:26Z","issue":"16","volume":127,"abstract":[{"lang":"eng","text":"We investigate the effect of coupling between translational and internal degrees of freedom of composite quantum particles on their localization in a random potential.

This situation restrains predictive theory. Here, we build on bacterial “growth laws,” which capture physiological feedback between translation and cell growth, to construct a minimal biophysical model for the combined action of ribosome-targeting antibiotics. Our model predicts drug interactions like antagonism or synergy solely from responses to individual drugs. We provide analytical results for limiting cases, which agree well with numerical results. We systematically refine the model by including direct physical interactions of different antibiotics on the ribosome. In a limiting case, our model provides a mechanistic underpinning for recent predictions of higher-order interactions that were derived using entropy maximization. We further refine the model to include the effects of antibiotics that mimic starvation and the presence of resistance genes. We describe the impact of a starvation-mimicking antibiotic on drug interactions analytically and verify it experimentally. Our extended model suggests a change in the type of drug interaction that depends on the strength of resistance, which challenges established rescaling paradigms. We experimentally show that the presence of unregulated resistance genes can lead to altered drug interaction, which agrees with the prediction of the model. While minimal, the model is readily adaptable and opens the door to predicting interactions of second and higher-order in a broad range of biological systems.","lang":"eng"}],"month":"01","volume":17,"date_updated":"2026-07-06T12:44:35Z","keyword":["Modelling and Simulation","Genetics","Molecular Biology","Antibiotics","Drug interactions"],"article_type":"original","related_material":{"record":[{"relation":"research_data","status":"public","id":"8930"},{"relation":"earlier_version","id":"7673","status":"public"}]},"date_published":"2021-01-07T00:00:00Z","article_number":"e1008529","author":[{"orcid":"0000-0001-6041-254X","last_name":"Kavcic","full_name":"Kavcic, Bor","id":"350F91D2-F248-11E8-B48F-1D18A9856A87","first_name":"Bor"},{"full_name":"Tkačik, Gašper","last_name":"Tkačik","orcid":"0000-0002-6699-1455","first_name":"Gašper","id":"3D494DCA-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Bollenbach","orcid":"0000-0003-4398-476X","full_name":"Bollenbach, Tobias","id":"3E6DB97A-F248-11E8-B48F-1D18A9856A87","first_name":"Tobias"}],"title":"Minimal biophysical model of combined antibiotic action","file":[{"date_created":"2021-02-04T12:30:48Z","file_size":3690053,"file_name":"2021_PlosComBio_Kavcic.pdf","content_type":"application/pdf","file_id":"9092","access_level":"open_access","checksum":"e29f2b42651bef8e034781de8781ffac","success":1,"creator":"dernst","relation":"main_file","date_updated":"2021-02-04T12:30:48Z"}],"publication":"PLOS Computational Biology","quality_controlled":"1","pmid":1,"publication_status":"published","day":"07","publisher":"Public Library of Science","doi":"10.1371/journal.pcbi.1008529","scopus_import":"1","acknowledgement":"This work was supported in part by Tum stipend of Knafelj foundation (to B.K.), Austrian Science Fund (FWF) standalone grants P 27201-B22 (to T.B.) and P 28844(to G.T.), HFSP program Grant RGP0042/2013 (to T.B.), German Research Foundation (DFG) individual grant BO 3502/2-1 (to T.B.), and German Research Foundation (DFG) Collaborative Research Centre (SFB) 1310 (to T.B.).

Among more common somatic genomic alterations are loss of heterozygosity (LOH). Large LOH events are potentially detectable in single cell RNA sequencing (scRNA-seq) datasets as tracts of monoallelic expression for constitutionally heterozygous single nucleotide variants (SNVs) located among contiguous genes. We identified runs of monoallelic expression, consistent with LOH, uniquely distributed throughout the genome in single cell brain cortex transcriptomes of F1 hybrids involving different inbred mouse strains. We then phylogenetically reconstructed single cell lineages and simultaneously identified cell types by corresponding gene expression patterns. Our results are consistent with progenitor cells giving rise to multiple cortical cell types through stereotyped expansion and distinct waves of neurogenesis. Compared to engineered recording systems, LOH events accumulate throughout the genome and across the lifetime of an organism, affording tremendous capacity for encoding lineage information and increasing resolution for later cell divisions. This approach can conceivably be computationally incorporated into scRNA-seq analysis and may be useful for organisms where genetic engineering is prohibitive, such as humans.","lang":"eng"}],"date_updated":"2026-07-06T12:46:11Z","language":[{"iso":"eng"}],"date_published":"2021-01-01T00:00:00Z","author":[{"first_name":"Donovan J.","full_name":"Anderson, Donovan J.","last_name":"Anderson"},{"first_name":"Florian","id":"48EA0138-F248-11E8-B48F-1D18A9856A87","full_name":"Pauler, Florian","last_name":"Pauler","orcid":"0000-0002-7462-0048"},{"full_name":"McKenna, Aaron","last_name":"McKenna","first_name":"Aaron"},{"first_name":"Jay","full_name":"Shendure, Jay","last_name":"Shendure"},{"orcid":"0000-0003-2279-1061","last_name":"Hippenmeyer","full_name":"Hippenmeyer, Simon","id":"37B36620-F248-11E8-B48F-1D18A9856A87","first_name":"Simon"},{"full_name":"Horwitz, Marshall S.","last_name":"Horwitz","first_name":"Marshall S."}],"title":"Simultaneous identification of brain cell type and lineage via single cell RNA sequencing","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2021-02-04T07:23:23Z","das_tickbox":"1","oa":1,"main_file_link":[{"url":"https://doi.org/10.1101/2020.12.31.425016","open_access":"1"}],"publication":"bioRxiv","ec_funded":1,"year":"2021","department":[{"_id":"SiHi"}],"publication_status":"submitted","project":[{"name":"Principles of Neural Stem Cell Lineage Progression in Cerebral Cortex Development","_id":"260018B0-B435-11E9-9278-68D0E5697425","grant_number":"725780","call_identifier":"H2020"}]},{"author":[{"id":"38C393BE-F248-11E8-B48F-1D18A9856A87","first_name":"Georgi A","last_name":"Dimchev","orcid":"0000-0001-8370-6161","full_name":"Dimchev, Georgi A"},{"last_name":"Amiri","full_name":"Amiri, Behnam","first_name":"Behnam"},{"first_name":"Florian","id":"404F5528-F248-11E8-B48F-1D18A9856A87","full_name":"Fäßler, Florian","orcid":"0000-0001-7149-769X","last_name":"Fäßler"},{"first_name":"Martin","full_name":"Falcke, Martin","last_name":"Falcke"},{"id":"48AD8942-F248-11E8-B48F-1D18A9856A87","first_name":"Florian KM","last_name":"Schur","orcid":"0000-0003-4790-8078","full_name":"Schur, Florian KM"}],"acknowledged_ssus":[{"_id":"ScienComp"},{"_id":"LifeSc"},{"_id":"Bio"},{"_id":"EM-Fac"}],"date_published":"2021-11-03T00:00:00Z","article_number":"107808","title":"Computational toolbox for ultrastructural quantitative analysis of filament networks in cryo-ET data","publication":"Journal of Structural Biology","file":[{"success":1,"checksum":"6b209e4d44775d4e02b50f78982c15fa","relation":"main_file","creator":"cchlebak","date_updated":"2021-11-15T13:11:27Z","date_created":"2021-11-15T13:11:27Z","file_size":16818304,"access_level":"open_access","content_type":"application/pdf","file_id":"10291","file_name":"2021_JournalStructBiol_Dimchev.pdf"}],"quality_controlled":"1","publication_status":"published","_id":"10290","status":"public","citation":{"ama":"Dimchev GA, Amiri B, Fäßler F, Falcke M, Schur FK.

This is particularly true for dynamic extra- and intracellular filamentous assemblies, playing a role in cell motility, cell integrity, cytokinesis, tissue formation and maintenance. For example, genetic manipulation or modulation of actin regulatory proteins frequently manifests in changes of the morphology, dynamics, and ultrastructural architecture of actin filament-rich cell peripheral structures, such as lamellipodia or filopodia. However, the observed ultrastructural effects often remain subtle and require sufficiently large datasets for appropriate quantitative analysis. The acquisition of such large datasets has been enabled by recent advances in high-throughput cryo-electron tomography (cryo-ET) methods. This also necessitates the development of complementary approaches to maximize the extraction of relevant biological information. We have developed a computational toolbox for the semi-automatic quantification of segmented and vectorized filamentous networks from pre-processed cryo-electron tomograms, facilitating the analysis and cross-comparison of multiple experimental conditions. GUI-based components simplify the processing of data and allow users to obtain a large number of ultrastructural parameters describing filamentous assemblies. We demonstrate the feasibility of this workflow by analyzing cryo-ET data of untreated and chemically perturbed branched actin filament networks and that of parallel actin filament arrays. In principle, the computational toolbox presented here is applicable for data analysis comprising any type of filaments in regular (i.e. parallel) or random arrangement. We show that it can ease the identification of key differences between experimental groups and facilitate the in-depth analysis of ultrastructural data in a time-efficient manner.","lang":"eng"}],"related_material":{"record":[{"relation":"software","status":"public","id":"14502"}]},"article_type":"original","keyword":["Structural Biology"],"corr_author":"1","external_id":{"isi":["000720259500002"]},"language":[{"iso":"eng"}],"file_date_updated":"2021-11-15T13:11:27Z","das_tickbox":"1","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2021-11-15T12:21:42Z","project":[{"_id":"9B954C5C-BA93-11EA-9121-9846C619BF3A","name":"Structure and isoform diversity of the Arp2/3 complex","grant_number":"P33367"},{"_id":"2674F658-B435-11E9-9278-68D0E5697425","name":"Protein structure and function in filopodia across scales","call_identifier":"FWF","grant_number":"M02495"}],"intvolume":"       213","year":"2021","department":[{"_id":"FlSc"}],"day":"03","publisher":"Elsevier","doi":"10.1016/j.jsb.2021.107808","scopus_import":"1","ddc":["572"],"acknowledgement":"This research was supported by the Scientific Service Units (SSUs) of IST Austria through resources provided by Scientific Computing (SciComp), the Life Science Facility (LSF), the BioImaging Facility (BIF), and the Electron Microscopy Facility (EMF).

If the mutation-free genotype is absent, generally the only stable equilibrium is the one that corresponds to fixation of the mutant allele at the locus where it is less deleterious. This result suggests that fixation of a deleterious allele that follows a click of the Muller’s ratchet is governed by natural selection, instead of random drift.","lang":"eng"}],"volume":524,"month":"04","date_updated":"2026-07-06T12:58:31Z","status":"public","_id":"9387","type":"journal_article","publication_identifier":{"issn":["0022-5193"]},"article_processing_charge":"No","citation":{"ista":"Khudiakova K, Neretina TY, Kondrashov AS. 2021.

These molecules or ions can end up in the particles as surface adsorbates and interfere in the material properties. This work demonstrates that ionic adsorbates, in particular Na⁺ ions, are electrostatically adsorbed in SnSe particles synthesized in water and play a crucial role not only in directing the material nano/microstructure but also in determining the transport properties of the consolidated material. In dense pellets prepared by sintering SnSe particles, Na remains within the crystal lattice as dopant, in dislocations, precipitates, and forming grain boundary complexions.

A broad theoretical framework was introduced by Jafargholi et al. [Crypto’17] for this purpose. In this paper we initiate the study of lower bounds on loss in adaptive security for certain cryptographic protocols considered in the framework. We prove lower bounds that almost match the upper bounds (proven using the framework) for proxy re-encryption, prefix-constrained PRFs and generalized selective decryption, a security game that captures the security of certain group messaging and broadcast encryption schemes. Those primitives have in common that their security game involves an underlying graph that can be adaptively built by the adversary. Some of our lower bounds only apply to a restricted class of black-box reductions which we term “oblivious” (the existing upper bounds are of this restricted type), some apply to the broader but still restricted class of non-rewinding reductions, while our lower bound for proxy re-encryption applies to all black-box reductions. The fact that some of our lower bounds seem to crucially rely on obliviousness or at least a non-rewinding reduction hints to the exciting possibility that the existing upper bounds can be improved by using more sophisticated reductions. Our main conceptual contribution is a two-player multi-stage game called the Builder-Pebbler Game. We can translate bounds on the winning probabilities for various instantiations of this game into cryptographic lower bounds for the above-mentioned primitives using oracle separation techniques."}],"month":"11","volume":13043,"related_material":{"record":[{"relation":"earlier_version","status":"public","id":"10048"}]},"isi":1,"oa_version":"Preprint","citation":{"ama":"Kamath Hosdurg C, Klein K, Pietrzak KZ, Walter M.
