In many familiar cases (e.g., Anosov systems) the growth is exponential, but arbitrarily fast growth is possible; in fact, the first author has shown that arbitrarily fast growth is topologically (Baire) generic for C2 or smoother diffeomorphisms. In the present work we show that, by contrast, for a measure-theoretic notion of genericity we call “prevalence”, the growth is not much faster than exponential. Specifically, we show that for each ρ,δ>0, there is a prevalent set of C1+ρ (or smoother) diffeomorphisms for which the number of periodic n points is bounded above by exp(Cn1+δ) for some C independent of n. We also obtain a related bound on the decay of hyperbolicity of the periodic points as a function of n, and obtain the same results for 1-dimensional endomorphisms. The contrast between topologically generic and measure-theoretically generic behavior for the growth of the number of periodic points and the decay of their hyperbolicity show this to be a subtle and complex phenomenon, reminiscent of KAM theory. Here in Part I we state our results and describe the methods we use. We complete most of the proof in the 1-dimensional C2-smooth case and outline the remaining steps, deferred to Part II, that are needed to establish the general case.\r\n\r\nThe novel feature of the approach we develop in this paper is the introduction of Newton Interpolation Polynomials as a tool for perturbing trajectories of iterated maps.","lang":"eng"}],"article_processing_charge":"No","publication_status":"published","month":"01","intvolume":"       165","language":[{"iso":"eng"}],"status":"public","_id":"8512","oa_version":"None","article_type":"original","issue":"1"},{"intvolume":"        81","month":"07","publication_status":"published","_id":"860","status":"public","issue":"1","page":"32 - 43","author":[{"first_name":"Olga","full_name":"Plotnikova, Olga V","last_name":"Plotnikova"},{"orcid":"0000-0001-8243-4694","full_name":"Fyodor Kondrashov","first_name":"Fyodor","id":"44FDEF62-F248-11E8-B48F-1D18A9856A87","last_name":"Kondrashov"},{"last_name":"Vlasov","full_name":"Vlasov, Peter K","first_name":"Peter"},{"last_name":"Grigorenko","first_name":"Anastasia","full_name":"Grigorenko, Anastasia P"},{"first_name":"Evgeny","full_name":"Ginter, Evgeny K","last_name":"Ginter"},{"full_name":"Rogaev, Evgeny I","first_name":"Evgeny","last_name":"Rogaev"}],"quality_controlled":0,"abstract":[{"lang":"eng","text":"We identified a mutation in the CRYGD gene (P23S) of the γ-crystallin gene cluster that is associated with a polymorphic congenital cataract that occurs with frequency of ∼0.3% in a human population. To gain insight into the molecular mechanism of the pathogenesis of γ-crystallin isoforms, we undertook an evolutionary analysis of the available mammalian and newly obtained primate sequences of the γ-crystallin genes. The cataract-associated serine at site 23 corresponds to the ancestral state, since it was found in CRYGD of a lower primate and all the surveyed nonprimate mammals. Crystallin proteins include two structurally similar domains, and substitutions in mammalian CRYGD protein at site 23 of the first domain were always associated with substitutions in the structurally reciprocal sites 109 and 136 of the second domain. These data suggest that the cataractogenic effect of serine at site 23 in the N-terminal domain of CRYGD may be compensated indirectly by amino acid changes in a distal domain. We also found that gene conversion was a factor in the evolution of the γ-crystallin gene cluster throughout different mammalian clades. The high rate of gene conversion observed between the functional CRYGD gene and two primate γ-crystallin pseudogenes (CRYGEP1 and CRYGFP1) coupled with a surprising finding of apparent negative selection in primate pseudogenes suggest a deleterious impact of recently derived pseudogenes involved in gene conversion in the γ-crystallin gene cluster."}],"acknowledgement":"This study was supported by the Biodiversity and Dynamics of Gene Pools program of the Presidium of the Russian Academy of Sciences (support to E.I.R.).

However, an up to date, manually curated database of mitochondrially encoded tRNAs from higher animals is currently not available. Description: We obtained the complete mitochondrial sequence for 277 tetrapod species from GenBank and re-annotated all of the tRNAs based on a multiple alignment of each tRNA gene and secondary structure prediction made independently for each tRNA. The mitochondrial (mt) tRNA sequences and the secondary structure based multiple alignments are freely available as Supplemental Information online. Conclusion: We compiled a manually curated database of mitochondrially encoded tRNAs from tetrapods with completely sequenced genomes. In the course of our work, we reannotated more than 10% of all tetrapod mt-tRNAs and subsequently predicted the secondary structures of 6060 mitochondrial tRNAs. This carefully constructed database can be utilized to enhance our knowledge in several different fields including the evolution of mt-tRNA secondary structure and prediction of pathogenic mt-tRNA mutations. In addition, researchers reporting novel mitochondrial genome sequences should check their tRNA gene annotations against our database to ensure a higher level of fidelity of their annotation."}],"type":"journal_article","date_created":"2018-12-11T11:48:54Z","tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"volume":8,"publist_id":"6789","date_published":"2007-11-14T00:00:00Z","extern":1,"doi":"10.1186/1471-2105-8-441","year":"2007","title":"A manually curated database of tetrapod mitochondrially encoded tRNA sequences and secondary structures","date_updated":"2021-01-12T08:20:18Z","citation":{"ama":"Popadin K, Mamirova L, Kondrashov F.

Initially, the Si capping layers are removed by etching selectively Si over Ge and then the composition of the disclosed islands is addressed by selectively etching Ge over Si. For samples grown at 580 °C the authors show that even when overgrowth leads to a flat Si surface and the islands undergo strong morphological changes, a Ge-rich core region is still preserved in the dot. At high growth and overgrowth temperatures (740 °C), the experiments show that the newly formed base of the buried islands is more Si rich than their top. Furthermore, the authors find that for the growth conditions used, no lateral motion takes place during capping."}],"author":[{"full_name":"Georgios Katsaros","first_name":"Georgios","id":"38DB5788-F248-11E8-B48F-1D18A9856A87","last_name":"Katsaros"},{"last_name":"Stoffel","full_name":"Stoffel, Mathieu","first_name":"Mathieu"},{"full_name":"Rastelli, Armando","first_name":"Armando","last_name":"Rastelli"},{"last_name":"Schmidt","full_name":"Schmidt, Oliver G","first_name":"Oliver"},{"full_name":"Kern, Klaus","first_name":"Klaus","last_name":"Kern"},{"first_name":"Jerry","full_name":"Tersoff, Jerry","last_name":"Tersoff"}],"quality_controlled":0},{"status":"public","_id":"1762","month":"12","intvolume":"       318","publication_status":"published","issue":"5858","quality_controlled":0,"author":[{"last_name":"Leek","full_name":"Leek, Peter J","first_name":"Peter"},{"id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","last_name":"Fink","orcid":"0000-0001-8112-028X","full_name":"Johannes Fink","first_name":"Johannes M"},{"last_name":"Blais","full_name":"Blais, Alexandre","first_name":"Alexandre"},{"first_name":"R","full_name":"Bianchetti, R","last_name":"Bianchetti"},{"first_name":"M","full_name":"Göppl, M","last_name":"Göppl"},{"last_name":"Gambetta","full_name":"Gambetta, Jay M","first_name":"Jay"},{"last_name":"Schuster","full_name":"Schuster, David I","first_name":"David"},{"last_name":"Frunzio","first_name":"Luigi","full_name":"Frunzio, Luigi"},{"first_name":"Robert","full_name":"Schoelkopf, Robert J","last_name":"Schoelkopf"},{"first_name":"Andreas","full_name":"Wallraff, Andreas","last_name":"Wallraff"}],"page":"1889 - 1892","acknowledgement":"Supported by the EC via an Intra-European Marie Curie Fellowship (P.J.L.), the Natural Sciences and Engineering Research Council of Canada, Canadian Institute for Advanced Research, and Fonds Québécois de la Recherche sur la Nature et les Technologies (A.B.), the National Security Agency under the Army Research Office, NSF, and Yale University (D.I.S., L.F., and R.J.S.), Consiglio Nazionale delle Ricerche–Istituto di Cibernetica, Pozzuoli, Italy (L.F.), the Ontario Research Development Challenge Fund and Mathematics of Information Technology and Complex Systems (J.M.G.), the Swiss National Science Foundation, and ETH Zürich","abstract":[{"lang":"eng","text":"In quantum information science, the phase of a wave function plays an important role in encoding information.

Bartha-strain derivatives spread only in the retrograde direction [13]. There is evidence that infected cells function normally for a while during GFP expression [7]. Here we combine transsynaptic PRV labeling, two-photon laser microscopy, and electrophysiological techniques to trace the local circuit of different ipRGC subtypes in the mouse retina and record light-evoked activity from the transsynaptically labeled ganglion cells. First, we show that ipRGCs are connected by monostratified amacrine cells that provide strong inhibition from classical-photoreceptor-driven circuits. Second, we show evidence that dopaminergic interplexiform cells are synaptically connected to ipRGCs. The latter finding provides a circuitry link between light-dark adaptation and ipRGC function.","lang":"eng"}],"date_created":"2018-12-11T11:54:04Z","type":"journal_article","volume":17,"publist_id":"5313","date_published":"2007-06-05T00:00:00Z","doi":"10.1016/j.cub.2007.04.058","extern":1,"title":"Local retinal circuits of melanopsin-containing ganglion cells identified by transsynaptic viral tracing","year":"2007","citation":{"chicago":"Viney, Tim, Kamill Bálint, Dániel Hillier, Sandra Siegert, Zsolt Boldogköi, Lynn Enquist, Markus Meister, Constance Cepko, and Botond Roska. “Local Retinal Circuits of Melanopsin-Containing Ganglion Cells Identified by Transsynaptic Viral Tracing.” <i>Current Biology</i>.

It catalyses the transfer of two electrons from NADH to quinone coupled to the translocation of four protons across the membrane. Although we have solved recently the crystal structure of the peripheral arm, the structure of the complete enzyme and the coupling mechanism are not yet known. The membrane domain of Escherichia coli complex I consists of seven different subunits with total molecular mass of 258 kDa. It is significantly more stable than the whole enzyme, which allowed us to obtain well-ordered two-dimensional crystals of the domain, belonging to the space group p22121. Comparison of the projection map of negatively stained crystals with previously published low-resolution structures indicated that the characteristic curved shape of the membrane domain is remarkably well conserved between bacterial and mitochondrial enzymes, helping us to interpret projection maps in the context of the intact complex. Two pronounced stain-excluding densities at the distal end of the membrane domain are likely to represent the two large antiporter-like subunits NuoL and NuoM. Cryo-electron microscopy on frozen-hydrated crystals allowed us to calculate a projection map at 8 Å resolution. About 60 transmembrane α-helices, both perpendicular to the membrane plane and tilted, are present within one membrane domain, which is consistent with secondary structure predictions. A possible binding site and access channel for quinone are found at the interface with the peripheral arm. Tentative assignment of individual subunits to the features of the map has been made. The location of subunits NuoL and NuoM at substantial distance from the peripheral arm, which contains all the redox centres of the complex, indicates that conformational changes are likely to play a role in the mechanism of coupling between electron transfer and proton pumping."}],"_id":"1965","status":"public","publication_status":"published","intvolume":"       366","month":"02","issue":"1","title":"Projection structure of the membrane domain of Escherichia coli respiratory Complex I at 8 Å resolution","year":"2007","date_updated":"2021-01-12T06:54:23Z","citation":{"ama":"Baranova E, Holt P, Sazanov LA.

When the internal surfaces of the 3D model are revealed as it is cut, carved, or simply clipped, we synthesize their texture from the input photographs. Our texture synthesis algorithm is best classified as a morphing technique, which efficiently outputs the texture attributes of each surface point on demand. For determining source points and their weights in the morphing algorithm, we propose an interpolation domain based on BSP trees that naturally resembles planar splitting of real objects. In the context of the interpolation domain, we define efficient warping and morphing operations that allow for real-time synthesis of textures. Overall, our modeling paradigm, together with its realization through our texture morphing algorithm, allow users to author 3D models that reveal highly realistic internal surfaces in a variety of artistic flavors."}],"acknowledgement":"This research was supported in part by the NCCR Co-Me of the Swiss National Science Foundation.
