In the primitive relay channel model, the source broadcasts a message to the relay and to the destination; and the relay facilitates this communication by sending an additional message to the destination through a separate channel. Two well-known coding approaches for this setting are decode-and-forward and compress-and-forward: in the former, the relay decodes the message and sends some of the information to the destination; in the latter, the relay does not attempt to decode, but it sends a compressed description of the received sequence to the destination via Wyner-Ziv coding. In our scheme, we transmit over pairs of blocks and we use compress-and-forward for the first block and decode-and-forward for the second. In particular, in the first block, the relay does not attempt to decode and it sends only a part of the compressed description of the received sequence; in the second block, the relay decodes the message and sends this information plus the remaining part of the compressed sequence relative to the first block. As a result, we strictly outperform both compress-and- forward and decode-and-forward. Furthermore, this paradigm can be implemented with a low-complexity polar coding scheme that has the typical attractive features of polar codes, i.e., quasi-linear encoding/decoding complexity and super-polynomial decay of the error probability. Throughout the paper we consider as a running example the special case of the erasure relay channel and we compare the rates achievable by our proposed scheme with the existing upper and lower bounds."}],"oa_version":"Preprint","author":[{"full_name":"Mondelli, Marco","orcid":"0000-0002-3242-7020","last_name":"Mondelli","id":"27EB676C-8706-11E9-9510-7717E6697425","first_name":"Marco"},{"last_name":"Hassani","full_name":"Hassani, Hamed","first_name":"Hamed"},{"first_name":"Rudiger","last_name":"Urbanke","full_name":"Urbanke, Rudiger"}],"external_id":{"arxiv":["1801.03153"]},"title":"A new coding paradigm for the primitive relay channel","date_updated":"2023-02-23T12:56:49Z","citation":{"ista":"Mondelli M, Hassani H, Urbanke R. 2018.

The structure consists of Sr2Pt3As layers alternating with Pt-only corrugated grids. Ab initio calculations predict a metallic character with a dominant role of the Pt d electrons. The electrical resistivity (ρ) and Seebeck coefficient confirm the metallic character, but surprisingly, ρ showed a near-flat temperature dependence. This observation fits the description of the Mooij correlation for electrical resistivity in disordered metals, originally developed for statistically distributed point defects. The discussed material has a long-range crystallographic order, but the high concentration of Pt vacancies, incommensurately ordered, strongly influences the electronic conduction properties. This result extends the range of validity of the Mooij correlation to long-range ordered incommensurately modulated vacancies. Motivated by the layered structure, the resistivity anisotropy was measured in a focused-ion-beam micro-fabricated well oriented single crystal. A low resistivity anisotropy indicates that the layers are electrically coupled and conduction channels along different directions are intermixed."}],"oa_version":"Published Version","author":[{"first_name":"Edoardo","last_name":"Martino","full_name":"Martino, Edoardo"},{"first_name":"Alla","full_name":"Arakcheeva, Alla","last_name":"Arakcheeva"},{"full_name":"Autès, Gabriel","last_name":"Autès","first_name":"Gabriel"},{"full_name":"Pisoni, Andrea","last_name":"Pisoni","first_name":"Andrea"},{"full_name":"Bachmann, Maja D.","last_name":"Bachmann","first_name":"Maja D."},{"orcid":"0000-0001-9760-3147","full_name":"Modic, Kimberly A","last_name":"Modic","first_name":"Kimberly A","id":"13C26AC0-EB69-11E9-87C6-5F3BE6697425"},{"first_name":"Toni","full_name":"Helm, Toni","last_name":"Helm"},{"first_name":"Oleg V.","full_name":"Yazyev, Oleg V.","last_name":"Yazyev"},{"full_name":"Moll, Philip J.

We find the electrical resistivity to be nearly independent of magnetic field up to 50 T: unusual for conventional metals but consistent with the chiral anomaly for Weyl fermions. Above 50 T we observe a two-order-of-magnitude increase in resistivity, indicating that a gap opens in the chiral Landau levels.

Measurement of the magnetotropic coefficient in the spin-liquid candidate RuCl3 highlights its sensitivity to anisotropic phase transitions and allows a quantitative comparison to other thermodynamic coefficients via the Ehrenfest relations.","lang":"eng"}],"issue":"1","volume":9,"file":[{"checksum":"46a313c816e66899d4dad2cf3583e5b0","file_id":"7088","content_type":"application/pdf","access_level":"open_access","relation":"main_file","date_created":"2019-11-20T12:48:58Z","file_name":"2018_NatureComm_Modic.pdf","date_updated":"2020-07-14T12:47:48Z","file_size":1257681,"creator":"dernst"}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["2041-1723"]},"publication_status":"published","status":"public","type":"journal_article","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"_id":"7059","file_date_updated":"2020-07-14T12:47:48Z","extern":"1","ddc":["530"],"date_updated":"2021-01-12T08:11:37Z","quality_controlled":"1","publisher":"Springer Nature","oa":1,"date_published":"2018-09-28T00:00:00Z","doi":"10.1038/s41467-018-06412-w","date_created":"2019-11-19T13:02:20Z","page":"3975","day":"28","publication":"Nature Communications","has_accepted_license":"1","year":"2018","title":"Resonant torsion magnetometry in anisotropic quantum materials","author":[{"id":"13C26AC0-EB69-11E9-87C6-5F3BE6697425","first_name":"Kimberly A","orcid":"0000-0001-9760-3147","full_name":"Modic, Kimberly A","last_name":"Modic"},{"last_name":"Bachmann","full_name":"Bachmann, Maja D.","first_name":"Maja D."},{"first_name":"B.

The analysis of the reported discontinuity in torque, as an external magnetic field is rotated across the c axis in both crystals, suggests that they have a translationally invariant chiral spin order of the form ⟨Si⋅(Sj×Sk)⟩≠0 in the ground state and persisting over a very wide range of magnetic field and temperature. An extraordinary |B|B2 dependence of the torque for small fields, beside the usual B2 part, is predicted by the chiral spin order.

Other experiments such as inelastic scattering and thermal Hall effect and several questions raised by the discovery of chiral spin order, including its topological consequences, are discussed.","lang":"eng"}],"intvolume":" 98","month":"11","main_file_link":[{"url":"https://arxiv.org/abs/1807.06637","open_access":"1"}],"extern":"1","date_updated":"2021-01-12T08:11:36Z","_id":"7058","status":"public","type":"journal_article","article_type":"original","publication":"Physical Review B","day":"05","year":"2018","date_created":"2019-11-19T13:01:31Z","doi":"10.1103/physrevb.98.205110","date_published":"2018-11-05T00:00:00Z","oa":1,"publisher":"APS","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Modic, Kimberly A, B.

In particular, there has been intensive research on reducing the communication cost of training when using multiple computational devices, through reducing the precision of the underlying data representation. Naturally, such methods induce system trade-offs—lowering communication precision could de-crease communication overheads and improve scalability; but, on the other hand, it can also reduce the accuracy of training. In this paper, we study this trade-off space, and ask:Can low-precision communication consistently improve the end-to-end performance of training modern neural networks, with no accuracy loss?From the performance point of view, the answer to this question may appear deceptively easy: compressing communication through low precision should help when the ratio between communication and computation is high. However, this answer is less straightforward when we try to generalize this principle across various neural network architectures (e.g., AlexNet vs. ResNet),number of GPUs (e.g., 2 vs. 8 GPUs), machine configurations(e.g., EC2 instances vs. NVIDIA DGX-1), communication primitives (e.g., MPI vs. NCCL), and even different GPU architectures(e.g., Kepler vs. Pascal). Currently, it is not clear how a realistic realization of all these factors maps to the speed up provided by low-precision communication. In this paper, we conduct an empirical study to answer this question and report the insights."}],"oa_version":"Published Version","scopus_import":1,"month":"03","publication_status":"published","publication_identifier":{"issn":["2367-2005"],"isbn":["9783893180783"]},"language":[{"iso":"eng"}],"file":[{"file_id":"7118","checksum":"ec979b56abc71016d6e6adfdadbb4afe","relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_name":"2018_OpenProceedings_Grubic.pdf","date_created":"2019-11-26T14:23:04Z","creator":"dernst","file_size":1603204,"date_updated":"2020-07-14T12:47:49Z"}],"license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","citation":{"mla":"Grubic, Demjan, et al. “Synchronous Multi-GPU Training for Deep Learning with Low-Precision Communications: An Empirical Study.” Proceedings of the 21st International Conference on Extending Database Technology, OpenProceedings, 2018, pp. 145–56, doi:10.5441/002/EDBT.2018.14.","ama":"Grubic D, Tam L, Alistarh D-A, Zhang C.

We show that the codes that achieve optimal compression in MDL are critical in a very precise sense. First, when they are taken as generative models of samples, they generate samples with broad empirical distributions and with a high value of the relevance, defined as the entropy of the empirical frequencies. These results are derived for different statistical models (Dirichlet model, independent and pairwise dependent spin models, and restricted Boltzmann machines). Second, MDL codes sit precisely at a second order phase transition point where the symmetry between the sampled outcomes is spontaneously broken. The order parameter controlling the phase transition is the coding cost of the samples. The phase transition is a manifestation of the optimality of MDL codes, and it arises because codes that achieve a higher compression do not exist. These results suggest a clear interpretation of the widespread occurrence of statistical criticality as a characterization of samples which are maximally informative on the underlying generative process.","lang":"eng"}],"oa_version":"Published Version","month":"10","intvolume":" 20","publication_identifier":{"issn":["1099-4300"]},"publication_status":"published","file":[{"content_type":"application/pdf","relation":"main_file","access_level":"open_access","checksum":"d642b7b661e1d5066b62e6ea9986b917","file_id":"7127","file_size":1366813,"date_updated":"2020-07-14T12:47:50Z","creator":"rcubero","file_name":"entropy-20-00755-v2.pdf","date_created":"2019-11-26T22:23:08Z"}],"language":[{"iso":"eng"}],"volume":20,"issue":"10","_id":"7126","article_type":"original","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"status":"public","keyword":["Minimum Description Length","normalized maximum likelihood","statistical criticality","phase transitions","large deviations"],"date_updated":"2021-01-12T08:11:56Z","extern":"1","ddc":["519"],"file_date_updated":"2020-07-14T12:47:50Z","quality_controlled":"1","publisher":"MDPI","oa":1,"has_accepted_license":"1","year":"2018","day":"01","publication":"Entropy","date_published":"2018-10-01T00:00:00Z","doi":"10.3390/e20100755","date_created":"2019-11-26T22:18:05Z","article_number":"755","citation":{"ista":"Cubero RJ, Marsili M, Roudi Y. 2018.

However, O2 evolution, as would be expected according to the decomposition reaction 2 Li2CO3→4 Li++4 e−+2 CO2+O2, is not detected. O atoms are thus unaccounted for, which was previously ascribed to unidentified parasitic reactions. Here, we show that highly reactive singlet oxygen (1O2) forms upon oxidizing Li2CO3 in an aprotic electrolyte and therefore does not evolve as O2.

The potential of hydrogels, such as those based on perylene bisimides, lies in their chemical, physical, optical, and electronic properties, which are governed by the supramolecular structure of the gel. However, the structural motifs and their precise role for long-range conductivity are yet to be explored. Here, we present a comprehensive structural picture of a perylene bisimide hydrogel, suggesting that its long-range conductivity is limited by charge transfer between electronic backbones. We reveal nanocrystalline ribbon-like structures as the electronic and structural backbone units between which charge transfer is mediated by polar solvent bridges. We exemplify this effect with sensing, where exposure to polar vapor enhances conductivity by 5 orders of magnitude, emphasizing the crucial role of the interplay between structural motif and surrounding medium for the rational design of devices based on nanocrystalline hydrogels."}],"intvolume":" 12","month":"06","language":[{"iso":"eng"}],"file":[{"checksum":"050f7f0ba5d845c5c71779ef14ad5ef3","file_id":"8052","access_level":"open_access","relation":"main_file","content_type":"application/pdf","date_created":"2020-06-29T14:56:40Z","file_name":"Manuscript 20092017_subm.pdf","creator":"sfreunbe","date_updated":"2020-07-14T12:47:55Z","file_size":1333353}],"publication_status":"published","publication_identifier":{"issn":["1936-0851"]},"issue":"6","volume":12,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"mla":"Burian, Max, et al. “Inter-Backbone Charge Transfer as Prerequisite for Long-Range Conductivity in Perylene Bisimide Hydrogels.” ACS Nano, vol. 12, no. 6, ACS, 2018, pp. 5800–06, doi:10.1021/acsnano.8b01689.","ieee":"M.

PoS were introduced as a more ecological and economical replacement for proofs of work which are currently used to secure blockchains like Bitcoin. In this work we investigate extensions of PoS which allow the prover to embed useful data into the dedicated space, which later can be recovered. Our first contribution is a security proof for the original PoS from CRYPTO'15 in the random oracle model (the original proof only applied to a restricted class of adversaries which can store a subset of the data an honest prover would store). When this PoS is instantiated with recent constructions of maximally depth robust graphs, our proof implies basically optimal security. As a second contribution we show three different extensions of this PoS where useful data can be embedded into the space required by the prover. Our security proof for the PoS extends (non-trivially) to these constructions. We discuss how some of these variants can be used as proofs of catalytic space (PoCS), a notion we put forward in this work, and which basically is a PoS where most of the space required by the prover can be used to backup useful data. Finally we discuss how one of the extensions is a candidate construction for a proof of replication (PoR), a proof system recently suggested in the Filecoin whitepaper.

Genes in the vicinity of these rsCpGs were found to be enriched in Homeobox transcription factors and the Wnt signalling pathway, both of which are related to ageing processes. Furthermore, we investigated the SNP effect on the random slope. We found that 4 out of 1507 rsCpGs had one significant (P < 5 × 10−8/1507) SNP effect and 343 rsCpGs had at least one SNP effect (436 SNP-probe pairs) reaching genome-wide significance (P < 5 × 10−8). Ninety-five percent of the significant (P < 5 × 10−8) SNPs are on different chromosomes from their corresponding probes.\r\nConclusions: We identified CpG sites that have variability in the rate of change of DNA methylation between individuals, and our results suggest a genetic basis of this variation.

While the motivation for undertaking genome-wide association studies (GWAS) is identification of genetic markers associated with complex traits, once generated these data can be used for many other analyses. GWAS have demonstrated that complex traits exhibit a highly polygenic genetic architecture, often with shared genetic risk factors across traits. New methods to analyse data from GWAS are increasingly being used to address a diverse set of questions about the aetiology of complex traits and diseases, including psychiatric disorders. Here, we give an overview of some of these methods and present examples of how they have contributed to our understanding of psychiatric disorders. We consider: (i) estimation of the extent of genetic influence on traits, (ii) uncovering of shared genetic control between traits, (iii) predictions of genetic risk for individuals, (iv) uncovering of causal relationships between traits, (v) identifying causal single-nucleotide polymorphisms and genes or (vi) the detection of genetic heterogeneity. This classification helps organise the large number of recently developed methods, although some could be placed in more than one category. While some methods require GWAS data on individual people, others simply use GWAS summary statistics data, allowing novel well-powered analyses to be conducted at a low computational burden."}],"extern":"1","date_updated":"2021-01-12T08:15:05Z","status":"public","article_type":"original","type":"journal_article","_id":"7721"},{"article_type":"original","type":"journal_article","status":"public","_id":"7754","article_number":"4348","article_processing_charge":"No","author":[{"last_name":"Goodrich","orcid":"0000-0002-1307-5074","full_name":"Goodrich, Carl Peter","id":"EB352CD2-F68A-11E9-89C5-A432E6697425","first_name":"Carl Peter"},{"full_name":"Brenner, Michael P.","last_name":"Brenner","first_name":"Michael P."},{"full_name":"Ribbeck, Katharina","last_name":"Ribbeck","first_name":"Katharina"}],"title":"Enhanced diffusion by binding to the crosslinks of a polymer gel","citation":{"apa":"Goodrich, C.

Thus, filtering requires the interacting particles to transiently reorganize the gel’s internal structure. While significant advances, e.g., in DNA engineering, have enabled the design of nano-materials with programmable interactions, it is not clear what physical principles such a designer gel could exploit to achieve selective permeability.
