The molecular charge-transfer distribution is topographically mapped, demonstrating that a uniformly delocalized passive electronic medium facilitates the charge-transfer between the phenolic electron donor and the cyano electron acceptors which lie at opposite ends of the molecule. Its ability to act as a “push–pull” π-conjugated molecule is quantified, relative to similar materials, by supporting empirical calculations; these include bond-length alternation and harmonic-oscillator stabilization energy (HOSE) tests. Such tests, together with frontier molecular orbital considerations, reveal that OH1 can exist readily in its aromatic (neutral) or quinoidal (charge-separated) state, thereby overcoming the “nonlinearity-thermal stability trade-off”. The HOSE calculation also reveals a correlation between the quinoidal resonance contribution to the overall structure of OH1 and the UV–vis absorption peak wavelength in the wider family of configurationally locked polyene framework materials. Solid-state tensorial coefficients of the molecular dipole, polarizability, and the first hyperpolarizability for OH1 are derived from the first-, second-, and third-order electronic moments of the experimental charge-density distribution. The overall solid-state molecular dipole moment is compared with those from gas-phase calculations, revealing that crystal field effects are very significant in OH1. The solid-state hyperpolarizability derived from this charge-density study affords good agreement with gas-phase calculations as well as optical measurements based on hyper-Rayleigh scattering (HRS) and electric-field-induced second harmonic (EFISH) generation. This lends support to the further use of charge-density studies to calculate solid-state hyperpolarizability coefficients in other organic NLO materials. Finally, this charge-density study is also employed to provide an advanced classification of hydrogen bonds in OH1, which requires more stringent criteria than those from conventional structure analysis. As a result, only the strongest OH···NC interaction is so classified as a true hydrogen bond. Indeed, it is this electrostatic interaction that influences the molecular charge transfer: the other four, weaker, nonbonded contacts nonetheless affect the crystal packing. Overall, the establishment of these structure–property relationships lays a blueprint for designing further, more NLO efficient, materials in this industrially leading organic family of compounds.","lang":"eng"}],"day":"09","publication_identifier":{"issn":["1932-7447","1932-7455"]},"doi":"10.1021/jp400648q","language":[{"iso":"eng"}],"quality_controlled":"1","page":"9416-9430","publisher":"American Chemical Society (ACS)","issue":"18","author":[{"first_name":"Tze-Chia","last_name":"Lin","full_name":"Lin, Tze-Chia"},{"first_name":"Jacqueline M.","last_name":"Cole","full_name":"Cole, Jacqueline M."},{"id":"4AD6785A-F248-11E8-B48F-1D18A9856A87","first_name":"Andrew P","last_name":"Higginbotham","orcid":"0000-0003-2607-2363","full_name":"Higginbotham, Andrew P"},{"full_name":"Edwards, Alison J.","last_name":"Edwards","first_name":"Alison J."},{"first_name":"Ross O.","last_name":"Piltz","full_name":"Piltz, Ross O."},{"full_name":"Pérez-Moreno, Javier","last_name":"Pérez-Moreno","first_name":"Javier"},{"first_name":"Ji-Youn","last_name":"Seo","full_name":"Seo, Ji-Youn"},{"last_name":"Lee","first_name":"Seung-Chul","full_name":"Lee, Seung-Chul"},{"last_name":"Clays","first_name":"Koen","full_name":"Clays, Koen"},{"first_name":"O-Pil","last_name":"Kwon","full_name":"Kwon, O-Pil"}],"_id":"6370","publication":"The Journal of Physical Chemistry C","intvolume":"       117","title":"Molecular origins of the high-performance nonlinear optical susceptibility in a phenolic polyene chromophore: Electron density distributions, hydrogen bonding, and ab initio calculations","month":"05","date_created":"2019-05-03T09:40:31Z","oa_version":"None","publication_status":"published"},{"publisher":"IST Austria","file_date_updated":"2020-07-14T12:47:30Z","language":[{"iso":"eng"}],"page":"23","pubrep_id":"124","month":"06","title":"Replacing competition with cooperation to achieve scalable lock-free FIFO queues ","alternative_title":["IST Austria Technical Report"],"department":[{"_id":"ToHe"}],"date_created":"2019-05-13T14:13:27Z","oa_version":"Published Version","publication_status":"published","author":[{"id":"40876CD8-F248-11E8-B48F-1D18A9856A87","full_name":"Henzinger, Thomas A","orcid":"0000−0002−2985−7724","last_name":"Henzinger","first_name":"Thomas A"},{"first_name":"Hannes","last_name":"Payer","full_name":"Payer, Hannes"},{"id":"4C7638DA-F248-11E8-B48F-1D18A9856A87","full_name":"Sezgin, Ali","first_name":"Ali","last_name":"Sezgin"}],"has_accepted_license":"1","_id":"6440","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","ddc":["000","005"],"file":[{"access_level":"open_access","relation":"main_file","creator":"dernst","file_id":"6441","checksum":"a219ba4eada6cd62befed52262ee15d4","file_size":549684,"date_created":"2019-05-13T14:11:39Z","file_name":"2013_TechRep_Henzinger.pdf","content_type":"application/pdf","date_updated":"2020-07-14T12:47:30Z"}],"oa":1,"abstract":[{"lang":"eng","text":"In order to guarantee that each method of a data structure updates the logical state exactly once, al-most all non-blocking implementations employ Compare-And-Swap (CAS) based synchronization. For FIFO  queue  implementations  this  translates  into  concurrent  enqueue  or  dequeue  methods competing among themselves to update the same variable, the tail or the head, respectively, leading to high contention and poor scalability. Recent non-blocking queue implementations try to alleviate high contentionby increasing the number of contention points, all the while using CAS-based synchronization. Furthermore, obtaining a wait-free implementation with competition is achieved by additional synchronization which leads to further degradation of performance.In this paper we formalize the notion of competitiveness of a synchronizing statement which can beused as a measure for the scalability of concurrent implementations.  We present a new queue implementation, the Speculative Pairing (SP) queue, which, as we show, decreases competitiveness by using Fetch-And-Increment (FAI) instead of CAS. We prove that the SP queue is linearizable and lock-free.We also show that replacing CAS with FAI leads to wait-freedom for dequeue methods without an adverse effect on performance.  In fact, our experiments suggest that the SP queue can perform and scale better than the state-of-the-art queue implementations."}],"day":"13","publication_identifier":{"issn":["2664-1690"]},"doi":"10.15479/AT:IST-2013-124-v1-1","type":"technical_report","date_published":"2013-06-13T00:00:00Z","year":"2013","citation":{"ieee":"T.

In this model, a porous-medium-type diffusive term and an advection term are in competition. The former induces forward motion, the latter may induce backward motion of the free boundary depending on the direction of advection. We deduce conditions on the growth of the initial data at the free boundary which ensure that at least initially the advection term is dominant. This implies local backward motion of the free boundary provided the advection is (locally) directed appropriately. Our result is based on a new class of moving test functions and Stampacchia's lemma.

Our first contribution is about the strategy complexity, i.e the memory required for winning strategies: we prove that over general infinite-state graphs, memoryless strategies are sufficient for finitary Büchi, and finite-memory suffices for finitary parity games. We then study pushdown games with boundedness conditions, with two contributions. First we prove a collapse result for pushdown games with ωB-conditions, implying the decidability of solving these games. Second we consider pushdown games with finitary parity along with stack boundedness conditions, and show that solving these games is EXPTIME-complete."}],"doi":"10.4230/LIPIcs.CSL.2013.181","day":"01","ddc":["000"],"volume":23,"author":[{"orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu","first_name":"Krishnendu","last_name":"Chatterjee","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Fijalkow","first_name":"Nathanaël","full_name":"Fijalkow, Nathanaël"}],"_id":"1374","scopus_import":1,"title":"Infinite-state games with finitary conditions","pubrep_id":"624","alternative_title":["LIPIcs"],"intvolume":"        23","publication_status":"published","department":[{"_id":"KrCh"}],"date_created":"2018-12-11T11:51:39Z","file_date_updated":"2020-07-14T12:44:47Z","page":"181 - 196","series_title":"Leibniz International Proceedings in Informatics","ec_funded":1,"quality_controlled":"1","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik"},{"conference":{"start_date":"2013-10-20","name":"FMCAD: Formal Methods in Computer-Aided Design","end_date":"2013-10-23","location":"Portland, OR, United States"},"publisher":"IEEE","language":[{"iso":"eng"}],"page":"18 - 25","quality_controlled":"1","ec_funded":1,"month":"12","title":"Distributed synthesis for LTL fragments","publication_status":"published","oa_version":"None","project":[{"call_identifier":"FWF","_id":"2584A770-B435-11E9-9278-68D0E5697425","grant_number":"P 23499-N23","name":"Modern Graph Algorithmic Techniques in Formal Verification"},{"name":"Rigorous Systems Engineering","grant_number":"S 11407_N23","_id":"25832EC2-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"},{"_id":"2581B60A-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"Quantitative Graph Games: Theory and Applications","grant_number":"279307"},{"_id":"25EE3708-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","grant_number":"267989","name":"Quantitative Reactive Modeling"},{"_id":"2587B514-B435-11E9-9278-68D0E5697425","name":"Microsoft Research Faculty Fellowship"}],"date_created":"2018-12-11T11:51:40Z","department":[{"_id":"KrCh"},{"_id":"ToHe"}],"author":[{"full_name":"Chatterjee, Krishnendu","orcid":"0000-0002-4561-241X","last_name":"Chatterjee","first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Thomas A","last_name":"Henzinger","orcid":"0000−0002−2985−7724","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87"},{"id":"2FC5DA74-F248-11E8-B48F-1D18A9856A87","first_name":"Jan","last_name":"Otop","full_name":"Otop, Jan"},{"last_name":"Pavlogiannis","first_name":"Andreas","full_name":"Pavlogiannis, Andreas","orcid":"0000-0002-8943-0722","id":"49704004-F248-11E8-B48F-1D18A9856A87"}],"publication":"13th International Conference on Formal Methods in Computer-Aided Design","_id":"1376","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","related_material":{"record":[{"id":"5406","relation":"earlier_version","status":"public"}]},"abstract":[{"lang":"eng","text":"We consider the distributed synthesis problem for temporal logic specifications.

Yet, it may be easy to formally specify a controller. For instance, for a pipelined processor it suffices to state that the visible behavior of the pipelined system should be identical to a non-pipelined reference system (Burch-Dill paradigm). We present a novel procedure to efficiently synthesize multiple Boolean control signals from a specification given as a quantified first-order formula (with a specific quantifier structure). Our approach uses uninterpreted functions to abstract details of the design. We construct an unsatisfiable SMT formula from the given specification. Then, from just one proof of unsatisfiability, we use a variant of Craig interpolation to compute multiple coordinated interpolants that implement the Boolean control signals. Our method avoids iterative learning and back-substitution of the control functions. We applied our approach to synthesize a controller for a simple two-stage pipelined processor, and present first experimental results."}],"day":"11","doi":"10.1109/FMCAD.2013.6679394","arxiv":1,"acknowledgement":"This research was supported by the European Commission through project\r\nDIAMOND  (FP7-2009-IST-4-248613), and  QUAINT  (I774-N23),  ","author":[{"last_name":"Hofferek","first_name":"Georg","full_name":"Hofferek, Georg"},{"full_name":"Gupta, Ashutosh","last_name":"Gupta","first_name":"Ashutosh","id":"335E5684-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Könighofer","first_name":"Bettina","full_name":"Könighofer, Bettina"},{"full_name":"Jiang, Jie","last_name":"Jiang","first_name":"Jie"},{"last_name":"Bloem","first_name":"Roderick","full_name":"Bloem, Roderick"}],"_id":"1385","title":"Synthesizing multiple boolean functions using interpolation on a single proof","date_created":"2018-12-11T11:51:43Z","department":[{"_id":"ToHe"}],"publication_status":"published","quality_controlled":"1","ec_funded":1,"page":"77 - 84","publisher":"IEEE","type":"conference","date_published":"2013-12-11T00:00:00Z","publist_id":"5825","oa":1,"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/1308.4767"}],"publication":"2013 Formal Methods in Computer-Aided Design","month":"12","project":[{"_id":"25832EC2-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"Rigorous Systems Engineering","grant_number":"S 11407_N23"},{"_id":"25EE3708-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","grant_number":"267989","name":"Quantitative Reactive Modeling"}],"oa_version":"Preprint","language":[{"iso":"eng"}],"conference":{"location":"Portland, OR, United States","end_date":"2013-10-23","start_date":"2013-10-20","name":"FMCAD: Formal Methods in Computer-Aided Design"}},{"language":[{"iso":"eng"}],"conference":{"name":"ICALP: Automata, Languages and Programming","start_date":"2013-07-08","end_date":"2013-07-12","location":"Riga, Latvia"},"has_accepted_license":"1","project":[{"call_identifier":"FWF","_id":"25832EC2-B435-11E9-9278-68D0E5697425","grant_number":"S 11407_N23","name":"Rigorous Systems Engineering"},{"call_identifier":"FP7","_id":"25EE3708-B435-11E9-9278-68D0E5697425","grant_number":"267989","name":"Quantitative Reactive Modeling"}],"oa_version":"Submitted Version","month":"07","file":[{"relation":"main_file","access_level":"open_access","creator":"dernst","file_id":"7857","checksum":"98bc02e3793072e279ec8d364b381ff3","file_size":276982,"date_created":"2020-05-15T11:05:50Z","file_name":"2013_ICALP_Boker.pdf","content_type":"application/pdf","date_updated":"2020-07-14T12:44:48Z"}],"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"conference","date_published":"2013-07-01T00:00:00Z","oa":1,"publist_id":"5823","quality_controlled":"1","ec_funded":1,"series_title":"Lecture Notes in Computer Science","page":"89 - 100","file_date_updated":"2020-07-14T12:44:48Z","publisher":"Springer","scopus_import":1,"_id":"1387","issue":"PART 2","author":[{"id":"31E297B6-F248-11E8-B48F-1D18A9856A87","full_name":"Boker, Udi","last_name":"Boker","first_name":"Udi"},{"first_name":"Denis","last_name":"Kuperberg","full_name":"Kuperberg, Denis"},{"full_name":"Kupferman, Orna","last_name":"Kupferman","first_name":"Orna"},{"last_name":"Skrzypczak","first_name":"Michał","full_name":"Skrzypczak, Michał"}],"department":[{"_id":"ToHe"}],"date_created":"2018-12-11T11:51:44Z","article_processing_charge":"No","publication_status":"published","intvolume":"      7966","alternative_title":["LNCS"],"title":"Nondeterminism in the presence of a diverse or unknown future","volume":7966,"acknowledgement":"and ERC Grant QUALITY.","ddc":["000"],"year":"2013","citation":{"chicago":"Boker, Udi, Denis Kuperberg, Orna Kupferman, and Michał Skrzypczak. “Nondeterminism in the Presence of a Diverse or Unknown Future.” Lecture Notes in Computer Science.

In several applications, most notably synthesis, the future is diverse or unknown, leading to algorithms that are based on deterministic automata. Hoping to retain some of the advantages of nondeterministic automata, researchers have studied restricted classes of nondeterministic automata. Three such classes are nondeterministic automata that are good for trees (GFT; i.e., ones that can be expanded to tree automata accepting the derived tree languages, thus whose choices should satisfy diverse futures), good for games (GFG; i.e., ones whose choices depend only on the past), and determinizable by pruning (DBP; i.e., ones that embody equivalent deterministic automata). The theoretical properties and relative merits of the different classes are still open, having vagueness on whether they really differ from deterministic automata. In particular, while DBP ⊆ GFG ⊆ GFT, it is not known whether every GFT automaton is GFG and whether every GFG automaton is DBP. Also open is the possible succinctness of GFG and GFT automata compared to deterministic automata. We study these problems for ω-regular automata with all common acceptance conditions. We show that GFT=GFG⊃DBP, and describe a determinization construction for GFG automata.","lang":"eng"}]},{"type":"dissertation","date_published":"2013-09-05T00:00:00Z","oa":1,"publist_id":"5802","supervisor":[{"first_name":"Thomas A","last_name":"Henzinger","orcid":"0000−0002−2985−7724","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87"}],"publication_identifier":{"issn":["2663-337X"]},"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","status":"public","related_material":{"record":[{"relation":"part_of_dissertation","id":"2847","status":"public"},{"status":"public","id":"3251","relation":"part_of_dissertation"},{"status":"public","id":"4361","relation":"part_of_dissertation"}]},"file":[{"success":1,"relation":"main_file","access_level":"open_access","file_id":"9176","creator":"dernst","date_created":"2021-02-22T11:28:36Z","file_size":1514906,"checksum":"ed2d7b52933d134e8dc69d569baa284e","date_updated":"2021-02-22T11:28:36Z","content_type":"application/pdf","file_name":"2013_Zufferey_thesis_final.pdf"},{"file_id":"10298","creator":"cchlebak","access_level":"closed","relation":"main_file","date_updated":"2021-11-17T13:47:58Z","content_type":"application/pdf","file_name":"2013_Zufferey_thesis_final_pdfa.pdf","date_created":"2021-11-16T14:42:52Z","file_size":1378313,"checksum":"cecc4c4b14225bee973d32e3dba91a55"}],"main_file_link":[{"url":"http://dzufferey.github.io/files/2013_thesis.pdf"}],"has_accepted_license":"1","month":"09","project":[{"name":"Rigorous Systems Engineering","grant_number":"S 11407_N23","_id":"25832EC2-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"},{"call_identifier":"FP7","_id":"25EE3708-B435-11E9-9278-68D0E5697425","name":"Quantitative Reactive Modeling","grant_number":"267989"}],"oa_version":"Published Version","language":[{"iso":"eng"}],"year":"2013","citation":{"ama":"Zufferey D.

Depth-bounded systems are one of the most expressive known fragment of the π-calculus for which interesting verification problems are still decidable. Even though they are infinite state systems depth-bounded systems are well-structured, thus can be analyzed algorithmically. We give an interpretation of depth-bounded systems as graph-rewriting systems. This gives more flexibility and ease of use to apply depth-bounded systems to other type of systems like shared memory concurrency.\r\n\r\nFirst, we develop an adequate domain of limits for depth-bounded systems, a prerequisite for the effective representation of downward-closed sets. Downward-closed sets are needed by forward saturation-based algorithms to represent potentially infinite sets of states. Then, we present an abstract interpretation framework to compute the covering set of well-structured transition systems. Because, in general, the covering set is not computable, our abstraction over-approximates the actual covering set. Our abstraction captures the essence of acceleration based-algorithms while giving up enough precision to ensure convergence. We have implemented the analysis in the PICASSO tool and show that it is accurate in practice.

Here we use zebrafish epiboly as a model system to study the cellular and molecular mechanisms underlying the spreading of epithelial sheets. During zebrafish epiboly the enveloping cell layer (EVL), a simple squamous epithelium, spreads over the embryo to eventually cover the entire yolk cell by the end of gastrulation. The EVL leading edge is anchored through tight junctions to the yolk syncytial layer (YSL), where directly adjacent to the EVL margin a contractile actomyosin ring is formed that is thought to drive EVL epiboly. The prevalent view in the field was that the contractile ring exerts a pulling force on the EVL margin, which pulls the EVL towards the vegetal pole. However, how this force is generated and how it affects EVL morphology still remains elusive. Moreover, the cellular mechanisms mediating the increase in EVL surface area, while maintaining tissue integrity and function are still unclear. Here we show that the YSL actomyosin ring pulls on the EVL margin by two distinct force-generating mechanisms. One mechanism is based on contraction of the ring around its circumference, as previously proposed. The second mechanism is based on actomyosin retrogade flows, generating force through resistance against the substrate. The latter can function at any epiboly stage even in situations where the contraction-based mechanism is unproductive. Additionally, we demonstrate that during epiboly the EVL is subjected to anisotropic tension, which guides the orientation of EVL cell division along the main axis (animal-vegetal) of tension. The influence of tension in cell division orientation involves cell elongation and requires myosin-2 activity for proper spindle alignment. Strikingly, we reveal that tension-oriented cell divisions release anisotropic tension within the EVL and that in the absence of such divisions, EVL cells undergo ectopic fusions. We conclude that forces applied to the EVL by the action of the YSL actomyosin ring generate a tension anisotropy in the EVL that orients cell divisions, which in turn limit tissue tension increase thereby facilitating tissue spreading.","lang":"eng"}],"citation":{"ista":"Campinho P. 2013.

A total of 90 species was recorded in the area, which together with literature data made a final list of 104 species. For several species this area is beyond the northern, north-eastern or north-western limits of their known distribution. We collected new data for 19 globally or locally threatened species. Tundra Swan Cygnus columbianus, Emperor Goose Anser canagica, American Golden Plover Pluvialis dominica, Western Sandpiper Calidris mauri, Semipalmated Sandpiper C. pusilla, Northern House Martin Delichon urbica and Barn Swallow Hirundo rustica were all confirmed to be breeding. Breeding of Brent Goose Branta bernicla nigricans, Spectacled Eider Somateria fischeri and Steller's Eider Polysticta stelleri was judged to be 'very likely'. There was no evidence for breeding of Ross's Gull Rhodostethia rosea despite several records. Two Eurasian Dotterels Eudromias morinellus were recorded displaying for the first time in the area, but the status of the species is unclear. The area is important for Snowy Owl Nyctea scandiaca, and as moulting grounds for Emperor Goose. Canada Goose Branta canadensis, Baikal Teal Anas formosa, Bar-tailed Godwit Limosa lapponica, Slaty-backed Gull Larus schistisagus, Thayer's Gull L. thayeri, Black-headed Gull L. ridibundus, White-tailed Eagle Haliaeetus albicilla, Steller's Sea Eagle H. pelagicus, Osprey Pandion haliaetus, Arctic Warbler Phylloscopus borealis and House Sparrow Passer domesticus are more likely to be rare vagrants or migrants.

The dynamic assembly results from a competition between self-propulsion of particles and an attractive interaction induced respectively by osmotic and phoretic effects and activated by light.

Internal tides can be generated by topographic horizontal scales ranging from hundreds of meters to tens of kilometers. State of the art topographic products barely resolve scales smaller than ∼10 km in the deep ocean. On these scales abyssal hills dominate ocean floor roughness. The impact of abyssal hill roughness on internal‐tide generation is evaluated in this study. The conversion of M2 barotropic to baroclinic tidal energy is calculated based on linear wave theory both in real and spectral space using the Shuttle Radar Topography Mission SRTM30_PLUS bathymetric product at 1/120° resolution with and without the addition of synthetic abyssal hill roughness. Internal tide generation by abyssal hills integrates to 0.1 TW globally or 0.03 TW when the energy flux is empirically corrected for supercritical slope (i.e., ∼10% of the energy flux due to larger topographic scales resolved in standard products in both cases). The abyssal hill driven energy conversion is dominated by mid‐ocean ridges, where abyssal hill roughness is large. Focusing on two regions located over the Mid‐Atlantic Ridge and the East Pacific Rise, it is shown that regionally linear theory predicts an increase of the energy flux due to abyssal hills of up to 100% or 60% when an empirical correction for supercritical slopes is attempted. Therefore, abyssal hills, unresolved in state of the art topographic products, can have a strong impact on internal tide generation, especially over mid‐ocean ridges.","lang":"eng"}],"doi":"10.1002/2013jc009212","day":"07","extern":"1","volume":118,"publication":"Journal of Geophysical Research: Oceans","month":"11","oa_version":"Published Version","language":[{"iso":"eng"}],"date_published":"2013-11-07T00:00:00Z","type":"journal_article","oa":1,"publication_identifier":{"issn":["2169-9275"]},"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","status":"public","main_file_link":[{"url":"https://doi.org/10.1002/2013JC009212","open_access":"1"}]}]
