Rev. Lett. 118, 095301 (2017)). Here we demonstrate that in the experimentally realized regime the angulon can be seen as a point charge on a 2-sphere interacting with a gauge field of a non-abelian magnetic monopole. Unlike in several other settings, the gauge fields of the angulon problem emerge in the real coordinate space, as opposed to the momentum space or some effective parameter space. Furthermore, we find a topological transition associated with making the monopole abelian, which takes place in the vicinity of the previously reported angulon instabilities. These results pave the way for studying topological phenomena in experiments on molecules trapped in superfluid helium nanodroplets, as well as on other realizations of orbital impurity problems.","lang":"eng"}],"scopus_import":"1","language":[{"iso":"eng"}],"article_number":"235301","volume":119,"doi":"10.1103/PhysRevLett.119.235301","external_id":{"isi":["000417132100007"],"arxiv":["1705.05162"]},"project":[{"_id":"25681D80-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","grant_number":"291734","name":"International IST Postdoc Fellowship Programme"},{"call_identifier":"H2020","_id":"25C6DC12-B435-11E9-9278-68D0E5697425","grant_number":"694227","name":"Analysis of quantum many-body systems"},{"name":"Quantum rotations in the presence of a many-body environment","grant_number":"P29902","_id":"26031614-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"}],"isi":1,"publisher":"American Physical Society","ec_funded":1,"publication":"Physical Review Letters","status":"public","date_created":"2018-12-11T11:49:36Z","type":"journal_article","day":"06","date_updated":"2025-04-14T07:26:54Z","arxiv":1,"year":"2017","publication_status":"published","oa_version":"Preprint","date_published":"2017-12-06T00:00:00Z","article_type":"original","corr_author":"1","author":[{"id":"38CB71F6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5973-0874","first_name":"Enderalp","last_name":"Yakaboylu","full_name":"Yakaboylu, Enderalp"},{"first_name":"Andreas","last_name":"Deuchert","full_name":"Deuchert, Andreas","id":"4DA65CD0-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-3146-6746"},{"full_name":"Lemeshko, Mikhail","first_name":"Mikhail","last_name":"Lemeshko","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6990-7802"}],"month":"12","issue":"23","citation":{"ista":"Yakaboylu E, Deuchert A, Lemeshko M. 2017.

This distinguishes it from earlier works that were fundamentally limited to fixed data representations and therefore incompatible with deep learning architectures. We show by experiments on CIFAR-100 and ImageNet ILSVRC 2012 data that iCaRL can learn many classes incrementally over a long period of time where other strategies quickly fail.

In contrast to previous work, which required that annotated training data must be available for all tasks, we consider a new setting, in which for some tasks, potentially most of them, only unlabeled training data is provided. Consequently, to solve all tasks, information must be transferred between tasks with labels and tasks without labels. Focusing on an instance-based transfer method we analyze two variants of this setting: when the set of labeled tasks is fixed, and when it can be actively selected by the learner. We state and prove a generalization bound that covers both scenarios and derive from it an algorithm for making the choice of labeled tasks (in the active case) and for transferring information between the tasks in a principled way. We also illustrate the effectiveness of the algorithm on synthetic and real data.

The outstanding functional properties of these materials stems from the relationship between their band structure and defect concentration, including charge carrier concentration and electronic conductivity character, which consequently affects their optoelectronic, optical, and plasmonic properties. This, combined with several metastable crystal phases and stoichiometries and the low energy of formation of defects, makes the reproducible synthesis of these materials, with tunable parameters, remarkable. Further to this, the review captures the progress of the hierarchical assembly of these NCs, which bridges the link between their discrete and collective properties. Their ubiquitous application set has cross-cut energy conversion (photovoltaics, photocatalysis, thermoelectrics), energy storage (lithium-ion batteries, hydrogen generation), emissive materials (plasmonics, LEDs, biolabelling), sensors (electrochemical, biochemical), biomedical devices (magnetic resonance imaging, X-ray computer tomography), and medical therapies (photochemothermal therapies, immunotherapy, radiotherapy, and drug delivery). The confluence of advances in the synthesis, assembly, and application of these NCs in the past decade has the potential to significantly impact society, both economically and environmentally.

However, its cost-effectiveness is seriously hampered by the relatively high production cost and low efficiency of current thermoelectric materials and devices. To overcome present challenges and enable a successful deployment of thermoelectric systems in their wide application range, materials with significantly improved performance need to be developed. Nanostructuration can help in several ways to reach the very particular group of properties required to achieve high thermoelectric performances. Nanodomains inserted within a crystalline matrix can provide large charge carrier concentrations without strongly influencing their mobility, thus allowing to reach very high electrical conductivities. Nanostructured materials contain numerous grain boundaries that efficiently scatter mid- and long-wavelength phonons thus reducing the thermal conductivity. Furthermore, nanocrystalline domains can enhance the Seebeck coefficient by modifying the density of states and/or providing type- and energy-dependent charge carrier scattering. All these advantages can only be reached when engineering a complex type of material, nanocomposites, with exquisite control over structural and chemical parameters at multiple length scales. Since current conventional nanomaterial production technologies lack such level of control, alternative strategies need to be developed and adjusted to the specifics of the field. A particularly suitable approach to produce nanocomposites with unique level of control over their structural and compositional parameters is their bottom-up engineering from solution-processed nanoparticles. In this work, we review the state-of-the-art of this technology applied to the thermoelectric field, including the synthesis of nanoparticles of suitable materials with precisely engineered composition and surface chemistry, their combination and consolidation into nanostructured materials, the strategies to electronically dope such materials and the attempts to fabricate thermoelectric devices using nanoparticle-based nanopowders and inks."}],"article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"volume":46,"external_id":{"pmid":["28470243"]},"doi":"10.1039/c6cs00567e"},{"publication_identifier":{"eissn":["1520-5002"],"issn":["0897-4756"]},"title":"Tuning branching in ceria nanocrystals","_id":"375","quality_controlled":"1","intvolume":"        29","publist_id":"7455","extern":"1","month":"04","citation":{"ama":"Berestok T, Guardia P, Blanco J, et al.

This combination of properties makes branched NCs particularly suitable for a range of applications where both interaction with the media and charge transport are involved. Herein we report on the colloidal synthesis of branched ceria NCs by means of a ligand-mediated overgrowth mechanism. In particular, the differential coverage of oleic acid as an X-type ligand at ceria facets with different atomic density, atomic coordination deficiency, and oxygen vacancy density resulted in a preferential growth in the [111] direction and thus in the formation of ceria octapods. Alcohols, through an esterification alcoholysis reaction, promoted faster growth rates that translated into nanostructures with higher geometrical complexity, increasing the branch aspect ratio and triggering the formation of side branches. On the other hand, the presence of water resulted in a significant reduction of the growth rate, decreasing the reaction yield and eliminating side branching, which we associate to a blocking of the surface reaction sites or a displacement of the alcoholysis reaction. Overall, adjusting the amounts of each chemical, well-defined branched ceria NCs with tuned number, thickness, and length of branches and with overall size ranging from 5 to 45 nm could be produced. We further demonstrate that such branched ceria NCs are able to provide higher surface areas and related oxygen storage capacities (OSC) than quasi-spherical NCs.\r\n\r\n"}]},{"doi":"10.1038/ncomms14081","volume":8,"scopus_import":"1","article_number":"14081","OA_type":"gold","language":[{"iso":"eng"}],"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","abstract":[{"lang":"eng","text":"Three-dimensional topological insulators are bulk insulators with Z 2 topological electronic order that gives rise to conducting light-like surface states. These surface electrons are exceptionally resistant to localization by non-magnetic disorder, and have been adopted as the basis for a wide range of proposals to achieve new quasiparticle species and device functionality. Recent studies have yielded a surprise by showing that in spite of resisting localization, topological insulator surface electrons can be reshaped by defects into distinctive resonance states. Here we use numerical simulations and scanning tunnelling microscopy data to show that these resonance states have significance well beyond the localized regime usually associated with impurity bands. At native densities in the model Bi2X3 (X=Bi, Te) compounds, defect resonance states are predicted to generate a new quantum basis for an emergent electron gas that supports diffusive electrical transport.

Above Tc, we observe fluence-dependent relaxation rates that begin at a temperature similar to the one where transport measurements first show signatures of antiferromagnetic correlations. Upon suppressing superconductivity with a magnetic field, it is found that the fluence and temperature dependence of relaxation rates are consistent with bimolecular recombination of electrons and holes across a gap (2ΔAF) originating from antiferromagnetic correlations which comprise the pseudogap in electron-doped cuprates. This can be used to learn about coupling between electrons and high-energy (ω&gt;2ΔAF) excitations in these compounds and set limits on the time scales on which antiferromagnetic correlations are static.","lang":"eng"}],"date_published":"2017-03-13T00:00:00Z","language":[{"iso":"eng"}],"volume":95,"author":[{"full_name":"Vishik, Inna","first_name":"Inna","last_name":"Vishik"},{"full_name":"Mahmood, Fahad","last_name":"Mahmood","first_name":"Fahad"},{"full_name":"Alpichshev, Zhanybek","first_name":"Zhanybek","last_name":"Alpichshev","orcid":"0000-0002-7183-5203","id":"45E67A2A-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Nuh","last_name":"Gedik","full_name":"Gedik, Nuh"},{"last_name":"Higgins","first_name":"Joshu","full_name":"Higgins, Joshu"},{"full_name":"Greene, Richard","first_name":"Richard","last_name":"Greene"}],"doi":"10.1103/PhysRevB.95.115125","issue":"11","citation":{"ama":"Vishik I, Mahmood F, Alpichshev Z, Gedik N, Higgins J, Greene R.

A fundamental barrier when parallelizing SGD is the high bandwidth cost of communicating gradient updates between nodes; consequently, several lossy compresion heuristics have been proposed, by which nodes only communicate quantized gradients. Although effective in practice, these heuristics do not always converge. In this paper, we propose Quantized SGD (QSGD), a family of compression schemes with convergence guarantees and good practical performance. QSGD allows the user to smoothly trade off communication bandwidth and convergence time: nodes can adjust the number of bits sent per iteration, at the cost of possibly higher variance. We show that this trade-off is inherent, in the sense that improving it past some threshold would violate information-theoretic lower bounds. QSGD guarantees convergence for convex and non-convex objectives, under asynchrony, and can be extended to stochastic variance-reduced techniques. When applied to training deep neural networks for image classification and automated speech recognition, QSGD leads to significant reductions in end-to-end training time. For instance, on 16GPUs, we can train the ResNet-152 network to full accuracy on ImageNet 1.8 × faster than the full-precision variant.

We examine training at reduced precision, both from a theoretical and practical perspective, and ask: is it possible to train models at end-to-end low precision with provable guarantees? Can this lead to consistent order-of-magnitude speedups? We mainly focus on linear models, and the answer is yes for linear models. We develop a simple framework called ZipML based on one simple but novel strategy called double sampling. Our ZipML framework is able to execute training at low precision with no bias, guaranteeing convergence, whereas naive quanti- zation would introduce significant bias. We val- idate our framework across a range of applica- tions, and show that it enables an FPGA proto- type that is up to 6.5 × faster than an implemen- tation using full 32-bit precision. We further de- velop a variance-optimal stochastic quantization strategy and show that it can make a significant difference in a variety of settings. When applied to linear models together with double sampling, we save up to another 1.7 × in data movement compared with uniform quantization. When training deep networks with quantized models, we achieve higher accuracy than the state-of-the- art XNOR-Net.

It couples the transfer of two electrons between NADH and quinone to translocation of four protons across the membrane. It is the largest protein assembly of bacterial and mitochondrial respiratory chains, composed, in mammals, of up to 45 subunits with a total molecular weight of ∼1 MDa. Bacterial enzyme is about half the size, providing the important “minimal” model of complex I. The l-shaped complex consists of a hydrophilic arm, where electron transfer occurs, and a membrane arm, where proton translocation takes place. Previously, we have solved the crystal structures of the hydrophilic domain of complex I from Thermus thermophilus and of the membrane domain from Escherichia coli, followed by the atomic structure of intact, entire complex I from T. thermophilus. Recently, we have solved by cryo-EM a first complete atomic structure of mammalian (ovine) mitochondrial complex I. Core subunits are well conserved from the bacterial version, whilst supernumerary subunits form an interlinked, stabilizing shell around the core. Subunits containing additional cofactors, including Zn ion, NADPH and phosphopantetheine, probably have regulatory roles. Dysfunction of mitochondrial complex I is implicated in many human neurodegenerative diseases. The structure of mammalian enzyme provides many insights into complex I mechanism, assembly, maturation and dysfunction, allowing detailed molecular analysis of disease-causing mutations.","lang":"eng"}],"publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"None","year":"2017","corr_author":"1","language":[{"iso":"eng"}],"editor":[{"full_name":"Wikström, Mårten","first_name":"Mårten","last_name":"Wikström"}],"author":[{"id":"338D39FE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0977-7989","last_name":"Sazanov","first_name":"Leonid A","full_name":"Sazanov, Leonid A"}],"citation":{"ista":"Sazanov LA. 2017.Structure of respiratory complex I: “Minimal” bacterial and “de luxe” mammalian versions.

In this work we consider the behavior of the Loschmidt echo in the many-body localized phase, which is characterized by emergent local integrals of motion and provides a generic example of nonergodic dynamics. We demonstrate that the fluctuations of the Loschmidt echo decay as a power law in time in the many-body localized phase, in contrast to the exponential decay in few-body ergodic systems. We consider the spin-echo generalization of the Loschmidt echo and argue that the corresponding correlation function saturates to a finite value in localized systems. Slow, power-law decay of fluctuations of such spin-echo-type overlap is related to the operator spreading and is present only in the many-body localized phase, but not in a noninteracting Anderson insulator. While most of the previously considered probes of dephasing dynamics could be understood by approximating physical spin operators with local integrals of motion, the Loschmidt echo and its generalizations crucially depend on the full expansion of the physical operators via local integrals of motion operators, as well as operators which flip local integrals of motion. Hence these probes allow one to get insights into the relation between physical operators and local integrals of motion and access the operator spreading in the many-body localized phase.","lang":"eng"}],"language":[{"iso":"eng"}],"volume":96,"doi":"10.1103/PhysRevB.96.014202","external_id":{"arxiv":["1701.07772"]},"oa":1,"publist_id":"7378","extern":"1","main_file_link":[{"url":"https://arxiv.org/abs/1701.07772","open_access":"1"}],"intvolume":"        96","title":"Loschmidt echo in many body localized phases","_id":"445","year":"2017","oa_version":"Preprint","publication_status":"published","date_published":"2017-07-12T00:00:00Z","author":[{"orcid":"0000-0002-2399-5827","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","first_name":"Maksym","last_name":"Serbyn","full_name":"Serbyn, Maksym"},{"first_name":"Dimitry","last_name":"Abanin","full_name":"Abanin, Dimitry"}],"month":"07","citation":{"apa":"Serbyn, M., &#38; Abanin, D.

Yet, due to the exceeding difficulty of creating stably spinning objects of asymmetric shape in a manual trial-and-error process, there has been little departure from rotationally symmetric designs. With modern 3D printing technologies, however, we can manufacture shapes of almost unbounded complexity at the press of a button, shifting this design complexity toward computation. In this article, we describe an algorithm to generate designs for spinning objects by optimizing their mass distribution: as input, the user provides a solid 3D model and a desired axis of rotation. Our approach then modifies the interior mass distribution such that the principal directions of the moment of inertia align with the target rotation frame. To create voids inside the model, we represent its volume with an adaptive multiresolution voxelization and optimize the discrete voxel fill values using a continuous, nonlinear formulation. We further optimize for rotational stability by maximizing the dominant principal moment. Our method is well-suited for a variety of 3D printed models, ranging from characters to abstract shapes. We demonstrate tops and yo-yos that spin surprisingly stably despite their asymmetric appearance.","lang":"eng"}],"doi":"10.1145/3068766","volume":60,"page":"92 - 99","acknowledgement":"This project was supported in part by the ERC Starting Grant iModel (StG-2012-306877).

Members of the kinesin-5 subfamily were initially described as unidirectional plus-end-directed motors and shown to produce piconewton forces. However, some fungal kinesin-5 motors are bidirectional. The force production of a bidirectional kinesin-5 has not yet been measured. Therefore, it remains unknown whether the mechanism of the unconventional minus-end-directed motility differs fundamentally from that of plus-end-directed stepping. Using force spectroscopy, we have measured here the forces that ensembles of purified budding yeast kinesin-5 Cin8 produce in microtubule gliding assays in both plus- and minus-end direction. Correlation analysis of pause forces demonstrated that individual Cin8 molecules produce additive forces in both directions of movement. In ensembles, Cin8 motors were able to produce single-motor forces up to a magnitude of ∼1.5 pN. Hence, these properties appear to be conserved within the kinesin-5 subfamily. Force production was largely independent of the directionality of movement, indicating similarities between the motility mechanisms for both directions. These results provide constraints for the development of models for the bidirectional motility mechanism of fission yeast kinesin-5 and provide insight into the function of this mitotic motor."}],"scopus_import":"1","OA_type":"hybrid","language":[{"iso":"eng"}],"quality_controlled":"1","intvolume":"       113","publication_identifier":{"eissn":["1542-0086"],"issn":["0006-3495"]},"file":[{"creator":"system","file_size":977192,"date_created":"2018-12-12T10:14:03Z","file_id":"5052","access_level":"open_access","date_updated":"2020-07-14T12:46:31Z","content_type":"application/pdf","relation":"main_file","checksum":"99a2474088e20ac74b1882c4fbbb45b1","file_name":"IST-2018-965-v1+1_2017_Duellberg_Ensembles_of.pdf"}],"title":"Ensembles of bidirectional kinesin Cin8 produce additive forces in both directions of movement","_id":"453","has_accepted_license":"1","ddc":["570"],"oa":1,"publist_id":"7369","department":[{"_id":"MaLo"}],"author":[{"last_name":"Fallesen","first_name":"Todd","full_name":"Fallesen, Todd"},{"first_name":"Johanna","last_name":"Roostalu","full_name":"Roostalu, Johanna"},{"orcid":"0000-0001-6335-9748","id":"459064DC-F248-11E8-B48F-1D18A9856A87","last_name":"Düllberg","first_name":"Christian F","full_name":"Düllberg, Christian F"},{"full_name":"Pruessner, Gunnar","first_name":"Gunnar","last_name":"Pruessner"},{"last_name":"Surrey","first_name":"Thomas","full_name":"Surrey, Thomas"}],"month":"11","citation":{"short":"T.

Many are also invasive, including species of termites, the red imported fire ant, and the Argentine ant. While invasive social insects have been a problem in Southern Europe for some time, Central Europa was free of invasive ant species until recently because most ants are adapted to warmer climates. Only in the 1990s, did Lasius neglectus, a close relative of the common black garden ant, arrive in Germany. First described in 1990 based on individuals collected in Budapest, the species has since been detected for example in France, Germany, Spain, England, and Kyrgyzstan. The species is spread with soil during construction work or plantings, and L. neglectus therefore is often found in parks and botanical gardens. Another invasive ant now spreading in southern Germany is Formica fuscocinerea, which occurs along rivers, including in the sandy floodplains of the river Isar. As is typical of pioneer species, F. fuscocinerea quickly becomes extremely abundant and therefore causes problems for example on playgrounds in Munich. All invasive ant species are characterized by cooperation across nests, leading to strongly interconnected, very large super-colonies. The resulting dominance results in the extinction of native ant species as well as other arthropod species and thus in the reduction of biodiversity."}],"article_processing_charge":"No","pubrep_id":"962","volume":46,"page":"105 - 116","file_date_updated":"2020-07-14T12:46:32Z","publication":"Rundgespräche Forum Ökologie","publisher":"Verlag Dr. Friedrich Pfeil","tmp":{"short":"CC BY-ND (4.0)","image":"/image/cc_by_nd.png","name":"Creative Commons Attribution-NoDerivatives 4.0 International (CC BY-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nd/4.0/legalcode"},"day":"04","type":"journal_article","date_updated":"2024-10-09T20:58:13Z","status":"public","date_created":"2018-12-11T11:46:35Z","corr_author":"1","publication_status":"published","oa_version":"Published Version","year":"2017","date_published":"2017-04-04T00:00:00Z","citation":{"mla":"Cremer, Sylvia. “Invasive Ameisen in Europa: Wie Sie Sich Ausbreiten Und Die Heimische Fauna Verändern.” <i>Rundgespräche Forum Ökologie</i>, vol. 46, Verlag Dr. Friedrich Pfeil, 2017, pp. 105–16.","apa":"Cremer, S.

However, whether developmental methylation reprogramming during the sporophytic life cycle of flowering plants regulates genes is presently unknown. Here we report a distinctive gene-targeted RNA-directed DNA methylation (RdDM) activity in the Arabidopsis thaliana male sexual lineage that regulates gene expression in meiocytes. Loss of sexual-lineage-specific RdDM causes mis-splicing of the MPS1 gene (also known as PRD2), thereby disrupting meiosis. Our results establish a regulatory paradigm in which de novo methylation creates a cell-lineage-specific epigenetic signature that controls gene expression and contributes to cellular function in flowering plants."}],"article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"OA_type":"green","scopus_import":"1","volume":50,"external_id":{"pmid":["29255257"]},"doi":"10.1038/s41588-017-0008-5","oa":1,"main_file_link":[{"open_access":"1","url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7611288/"}],"extern":"1","department":[{"_id":"XiFe"}],"intvolume":"        50","quality_controlled":"1","_id":"12193","title":"Sexual-lineage-specific DNA methylation regulates meiosis in Arabidopsis","publication_identifier":{"eissn":["1546-1718"],"issn":["1061-4036"]},"date_published":"2017-12-18T00:00:00Z","OA_place":"repository","publication_status":"published","oa_version":"Submitted Version","year":"2017","article_type":"original","keyword":["Genetics"],"author":[{"full_name":"Walker, James","last_name":"Walker","first_name":"James"},{"full_name":"Gao, Hongbo","last_name":"Gao","first_name":"Hongbo"},{"last_name":"Zhang","first_name":"Jingyi","full_name":"Zhang, Jingyi"},{"full_name":"Aldridge, Billy","first_name":"Billy","last_name":"Aldridge"},{"full_name":"Vickers, Martin","first_name":"Martin","last_name":"Vickers"},{"last_name":"Higgins","first_name":"James D.","full_name":"Higgins, James D."},{"id":"e0164712-22ee-11ed-b12a-d80fcdf35958","orcid":"0000-0002-4008-1234","first_name":"Xiaoqi","last_name":"Feng","full_name":"Feng, Xiaoqi"}],"issue":"1","citation":{"ama":"Walker J, Gao H, Zhang J, et al.
