Through X-ray photoemission spectroscopy and X-ray absorption measurements, we find that the molecule fragments at the Sn–benzyl bond when exposed to Au surfaces at temperatures as low as −110 °C. The resulting benzyl species is stabilized by the presence of Au(111) but only forms covalent Au–C bonds on more reactive Au surfaces like Au(110). We also present spectroscopic proof for the existence of an electronic “gateway” state localized on the Au–C bond that is responsible for its unique electronic properties. Finally, we use DFT-based nudged elastic band calculations to elucidate the crucial role played by the under-coordinated Au surface in the formation of Au–C bonds."}],"date_updated":"2025-01-02T13:49:12Z","publication":"Journal of the American Chemical Society","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","pmid":1,"date_published":"2014-08-14T00:00:00Z","citation":{"ieee":"A.

Here, we demonstrate that the energy profile for metallic single-atom contacts and single-molecule junctions can be mapped by fitting ambient atomic force microscope measurements carried out in the near-equilibrium regime to a physical, but simple, functional form. We extract bond energies for junctions formed through metallic bonds as well as metal–molecule link bonds from atomic force microscope data and find that our results are in excellent quantitative agreement with density functional theory based calculations for exemplary junction structures. Furthermore, measurements from a large number of junctions can be collapsed to a single, universal force–extension curve, thus revealing a surprising degree of similarity in the overall shape of the potential surface that governs these chemical bonds. Compared to previous studies under ambient conditions where analysis was confined to trends in rupture force, our approach significantly expands the quantitative information extracted from these measurements, particularly allowing analysis of the trends in bond energy directly.","lang":"eng"}],"title":"Quantitative bond energetics in atomic-scale junctions","author":[{"full_name":"Aradhya, Sriharsha V.","last_name":"Aradhya","first_name":"Sriharsha V."},{"full_name":"Nielsen, Aileen","last_name":"Nielsen","first_name":"Aileen"},{"last_name":"Hybertsen","first_name":"Mark S.","full_name":"Hybertsen, Mark S."},{"full_name":"Venkataraman, Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","last_name":"Venkataraman","first_name":"Latha","orcid":"0000-0002-6957-6089"}],"external_id":{"pmid":["24945851"]},"date_created":"2024-09-09T11:07:34Z","type":"journal_article","publication_identifier":{"issn":["1936-0851"],"eissn":["1936-086X"]},"status":"public","volume":8,"page":"7522-7530","issue":"7","doi":"10.1021/nn502836e","extern":"1","year":"2014","language":[{"iso":"eng"}],"month":"06"},{"OA_type":"green","date_published":"2014-04-18T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","pmid":1,"publication":"Nano Letters","date_updated":"2025-01-02T14:11:49Z","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1411.5463"}],"abstract":[{"lang":"eng","text":"We have designed and synthesized five azulene derivatives containing gold-binding groups at different points of connectivity within the azulene core to probe the effects of quantum interference through single-molecule conductance measurements. We compare conducting paths through the 5-membered ring, 7-membered ring, and across the long axis of azulene. We find that changing the points of connectivity in the azulene impacts the optical properties (as determined from UV–vis absorption spectra) and the conductivity. Importantly, we show here that simple models cannot be used to predict quantum interference characteristics of nonalternant hydrocarbons. As an exemplary case, we show that azulene derivatives that are predicted to exhibit destructive interference based on widely accepted atom-counting models show a significant conductance at low biases. Although simple models to predict the low-bias conductance do not hold with all azulene derivatives, we demonstrate that the measured conductance trend for all molecules studied actually agrees with predictions based on the more complete GW calculations for model systems."}],"date_created":"2024-09-09T11:09:56Z","external_id":{"arxiv":["1411.5463"],"pmid":["24745894"]},"author":[{"first_name":"Jianlong","last_name":"Xia","full_name":"Xia, Jianlong"},{"last_name":"Capozzi","first_name":"Brian","full_name":"Capozzi, Brian"},{"last_name":"Wei","first_name":"Sujun","full_name":"Wei, Sujun"},{"full_name":"Strange, Mikkel","first_name":"Mikkel","last_name":"Strange"},{"first_name":"Arunabh","last_name":"Batra","full_name":"Batra, Arunabh"},{"first_name":"Jose R.","last_name":"Moreno","full_name":"Moreno, Jose R."},{"full_name":"Amir, Roey J.","last_name":"Amir","first_name":"Roey J."},{"last_name":"Amir","first_name":"Elizabeth","full_name":"Amir, Elizabeth"},{"last_name":"Solomon","first_name":"Gemma C.","full_name":"Solomon, Gemma C."},{"first_name":"Latha","last_name":"Venkataraman","orcid":"0000-0002-6957-6089","full_name":"Venkataraman, Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf"},{"last_name":"Campos","first_name":"Luis M.","full_name":"Campos, Luis M."}],"title":"Breakdown of interference rules in azulene, a nonalternant hydrocarbon","day":"18","_id":"17985","oa_version":"Preprint","article_processing_charge":"No","article_type":"letter_note","scopus_import":"1","intvolume":"        14","publisher":"American Chemical Society","quality_controlled":"1","citation":{"apa":"Xia, J., Capozzi, B., Wei, S., Strange, M., Batra, A., Moreno, J.

In most prior work, the same metal, typically Au, Pt, or Ag, is used for both tip and substrate. For such noble metal electrodes, the density of electronic states is approximately constant within a narrow energy window relevant to charge transport. Here, we form molecular junctions using the STM-BJ technique, with an Au metal tip and a microfabricated graphite substrate, and measure the conductance of a series of graphite/amine-terminated oligophenyl/Au molecular junctions. The remarkable mechanical strength of graphite and the single-crystal properties of our substrates allow measurements over few thousand junctions without any change in the surface properties. We show that conductance decays exponentially with molecular backbone length with a decay constant that is essentially the same as that for measurements with two Au electrodes. More importantly, despite the inherent symmetry of the oligophenylamines, we observe rectification in these junctions. State-of-art ab initio conductance calculations are in good agreement with experiment, and explain the rectification. We show that the highly energy-dependent graphite density of states contributes variations in transmission that, when coupled with an asymmetric voltage drop across the junction, leads to the observed rectification. Together, our measurements and calculations show how functionality may emerge from hybrid molecular-scale devices purposefully designed with different electrodes beyond the so-called “wide band limit,” opening up the possibility of assembling molecular junctions with dissimilar electrodes using layered 2D materials.","lang":"eng"}],"date_updated":"2025-01-03T07:49:30Z","intvolume":"       111","scopus_import":"1","article_type":"original","oa_version":"None","article_processing_charge":"No","_id":"17990","day":"14","quality_controlled":"1","citation":{"ista":"Kim T, Liu Z-F, Lee C, Neaton JB, Venkataraman L. 2014.

It mediates basically all multicellular development ranging from embryogenesis and de novo organ formation till responses to various environmental stimuli. In plants, the awe-inspiring number of such processes is regulated by phytohormone auxin and its directional, cell-to-cell transport. The mediators of this transport, PIN auxin transporters, are asymmetrically localized at the plasma membrane, and this polar localization determines the directionality of intercellular auxin flow. Thus, auxin transport contributes crucially to the generation of local auxin gradients or maxima, which instruct given cell to change its developmental program. Here, we introduce and discuss the molecular components and cellular mechanisms regulating the generation and maintenance of cellular PIN polarity, as the general hallmarks of cell polarity in plants.","lang":"eng"}],"date_updated":"2024-10-09T20:55:54Z","publication":"Auxin and Its Role in Plant Development","language":[{"iso":"eng"}],"publication_status":"published","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","year":"2014","page":"143 - 170","corr_author":"1","doi":"10.1007/978-3-7091-1526-8_8","date_published":"2014-04-01T00:00:00Z","quality_controlled":"1","citation":{"ista":"Baster P, Friml J. 2014.Auxin on the road navigated by cellular PIN polarity.

The embedding process may result in a change of the topology of the input data, e.g., by introducing self-intersections, which is undesirable or even disastrous for many applications. In this paper we present a watermarking framework for two-dimensional vector graphics that employs conventional watermarking techniques but still provides the guarantee that the topology of the input data is preserved. The geometric part of this framework computes so-called maximum perturbation regions (MPR) of vertices. We propose two efficient algorithms to compute MPRs based on Voronoi diagrams and constrained triangulations. Furthermore, we present two algorithms to conditionally correct the watermarked data in order to increase the watermark embedding capacity and still guarantee topological correctness. While we focus on the watermarking of input formed by straight-line segments, one of our approaches can also be extended to circular arcs. We conclude the paper by demonstrating and analyzing the applicability of our framework in conjunction with two well-known watermarking techniques.","lang":"eng"}],"author":[{"first_name":"Stefan","last_name":"Huber","orcid":"0000-0002-8871-5814","id":"4700A070-F248-11E8-B48F-1D18A9856A87","full_name":"Huber, Stefan"},{"full_name":"Held, Martin","first_name":"Martin","last_name":"Held"},{"full_name":"Meerwald, Peter","last_name":"Meerwald","first_name":"Peter"},{"last_name":"Kwitt","first_name":"Roland","full_name":"Kwitt, Roland"}],"title":"Topology-preserving watermarking of vector graphics","date_created":"2018-12-11T11:54:10Z","day":"16","oa_version":"Published Version","_id":"1816","scopus_import":1,"department":[{"_id":"HeEd"}],"intvolume":"        24","publist_id":"5290","publisher":"World Scientific Publishing","quality_controlled":"1","citation":{"mla":"Huber, Stefan, et al. “Topology-Preserving Watermarking of Vector Graphics.” <i>International Journal of Computational Geometry and Applications</i>, vol. 24, no. 1, World Scientific Publishing, 2014, pp. 61–86, doi:<a href=\"https://doi.org/10.1142/S0218195914500034\">10.1142/S0218195914500034</a>.","short":"S.

The fraction of atoms that are transported over the entire distance comes near to unity, while the heating of the cloud is in the range of a few microkelvin. We characterize the position stability of the focus and show that residual drift rates in focus position can be compensated for by counteracting with the tunable lenses. Beyond being a compact and robust scheme to transport ultracold atoms, the reported control of laser beams makes dynamic tailoring of trapping potentials possible.

These predictions get more accurate over time, hence the behaviors need to be continuously modified. As a result, movement templates with a learned global shape need to be adapted during the execution so that the racket reaches a target position and velocity that will return the ball over to the other side of the net or court. It requires altering learned movements to hit a varying target with the necessary velocity at a specific instant in time. Such a task cannot be incorporated straightforwardly in most movement representations suitable for learning. For example, the standard formulation of the dynamical system based motor primitives (introduced by Ijspeert et al (2002b)) does not satisfy this property despite their flexibility which has allowed learning tasks ranging from locomotion to kendama. In order to fulfill this requirement, we reformulate the Ijspeert framework to incorporate the possibility of specifying a desired hitting point and a desired hitting velocity while maintaining all advantages of the original formulation.We show that the proposed movement template formulation works well in two scenarios, i.e., for hitting a ball on a string with a table tennis racket at a specified velocity and for returning balls launched by a ball gun successfully over the net using forehand movements."}],"scopus_import":1,"intvolume":"        97","department":[{"_id":"ChLa"}],"alternative_title":["Springer Tracts in Advanced Robotics"],"day":"01","_id":"1829","series_title":"From Algorithms to Robot Experiments","type":"book_chapter","oa_version":"None","volume":97,"citation":{"chicago":"Muelling, Katharina, Oliver Kroemer, Christoph Lampert, and Bernhard Schölkopf. “Movement Templates for Learning of Hitting and Batting.” In <i>Learning Motor Skills</i>, edited by Jens Kober and Jan Peters, 97:69–82.

These geometries are typically defined using either the shortest path length (geodesic distance), or properties of heat diffusion (diffusion distance) on the surface. Both measures are implicitly derived from the metric induced by the ambient Euclidean space. In this paper, we depart from this restrictive assumption by observing that a different choice of the metric results in a richer set of geometric invariants. We apply equi-affine geometry for analyzing arbitrary shapes with positive Gaussian curvature. The potential of the proposed framework is explored in a range of applications such as shape matching and retrieval, symmetry detection, and computation of Voroni tessellation. We show that in some shape analysis tasks, equi-affine-invariant intrinsic geometries often outperform their Euclidean-based counterparts. We further explore the potential of this metric in facial anthropometry of newborns. We show that intrinsic properties of this homogeneous group are better captured using the equi-affine metric.","lang":"eng"}],"month":"09","title":"Equi-affine invariant geometry for shape analysis","author":[{"first_name":"Dan","last_name":"Raviv","full_name":"Raviv, Dan"},{"orcid":"0000-0001-9699-8730","last_name":"Bronstein","first_name":"Alexander","id":"58f3726e-7cba-11ef-ad8b-e6e8cb3904e6","full_name":"Bronstein, Alexander"},{"last_name":"Bronstein","first_name":"Michael M.","full_name":"Bronstein, Michael M."},{"last_name":"Waisman","first_name":"Dan","full_name":"Waisman, Dan"},{"last_name":"Sochen","first_name":"Nir","full_name":"Sochen, Nir"},{"full_name":"Kimmel, Ron","last_name":"Kimmel","first_name":"Ron"}],"date_created":"2024-10-15T11:20:54Z","date_published":"2014-09-01T00:00:00Z","page":"144-163","doi":"10.1007/s10851-013-0467-y","extern":"1","publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2014","language":[{"iso":"eng"}],"publication":"Journal of Mathematical Imaging and Vision"},{"author":[{"full_name":"Sprechmann, Pablo","last_name":"Sprechmann","first_name":"Pablo"},{"first_name":"Alexander","last_name":"Bronstein","orcid":"0000-0001-9699-8730","id":"58f3726e-7cba-11ef-ad8b-e6e8cb3904e6","full_name":"Bronstein, Alexander"},{"last_name":"Sapiro","first_name":"Guillermo","full_name":"Sapiro, Guillermo"}],"title":"Supervised non-euclidean sparse NMF via bilevel optimization with applications to speech enhancement","date_created":"2024-10-15T11:20:54Z","month":"06","abstract":[{"text":"Traditionally, NMF algorithms consist of two separate stages: a training stage, in which a generative model is learned; and a testing stage in which the pre-learned model is used in a high level task such as enhancement, separation, or classification.

For example, they have been successfully employed in correspondence, registration, and retrieval tasks. In recent years, significant attention has been devoted to descriptors obtained from the spectral decomposition of the Laplace-Beltrami operator associated with the shape. Notable examples in this family are the heat kernel signature (HKS) and the recently introduced wave kernel signature (WKS). The Laplacian-based descriptors achieve state-of-the-art performance in numerous shape analysis tasks; they are computationally efficient, isometry-invariant by construction, and can gracefully cope with a variety of transformations. In this paper, we formulate a generic family of parametric spectral descriptors. We argue that to be optimized for a specific task, the descriptor should take into account the statistics of the corpus of shapes to which it is applied (the \"signal\") and those of the class of transformations to which it is made insensitive (the \"noise\"). While such statistics are hard to model axiomatically, they can be learned from examples. Following the spirit of the Wiener filter in signal processing, we show a learning scheme for the construction of optimized spectral descriptors and relate it to Mahalanobis metric learning. The superiority of the proposed approach in generating correspondences is demonstrated on synthetic and scanned human figures. We also show that the learned descriptors are robust enough to be learned on synthetic data and transferred successfully to scanned shapes."}],"date_updated":"2024-12-12T12:42:56Z","date_created":"2024-10-15T11:20:55Z","external_id":{"pmid":["24231874"]},"title":"Learning spectral descriptors for deformable shape correspondence","author":[{"first_name":"R.","last_name":"Litman","full_name":"Litman, R."},{"id":"58f3726e-7cba-11ef-ad8b-e6e8cb3904e6","full_name":"Bronstein, Alexander","orcid":"0000-0001-9699-8730","last_name":"Bronstein","first_name":"Alexander"}],"_id":"18413","oa_version":"None","article_processing_charge":"No","day":"01","intvolume":"        36","scopus_import":"1","publisher":"IEEE","quality_controlled":"1","citation":{"ieee":"R.
