The molecular events behind this fibril surface-mediated process remain largely inaccessible to current structural and imaging techniques. Using statistical mechanics, computer modeling, and chemical kinetics, we show that the catalytic structure of the fibril surface can be inferred from the aggregation behavior in the presence and absence of a fibril-binding inhibitor. We apply our approach to the case of Alzheimer’s A\r\n amyloid fibrils formed in the presence of proSP-C Brichos inhibitors.

In certain parameter regimes, just a few terms are enough for our recurrent procedure to predict ground-state energies close to the exact ones for several hundreds of sites.

Moreover, the usual growth conditions on the multiplicative noise are weakened considerably. Our new setting provides general conditions under which local and global existence and uniqueness hold. Moreover, we prove continuous dependence on the initial data. We show that many classical SPDEs, which could not be covered by the classical variational setting, do fit in the critical variational setting.

However, this restriction to trees leads to a construction that has time quadratic in the size of the network and does not parallelize well. \r\nIn this paper we study oblivious routing schemes based on electrical routing. In particular, we show that general networks with n vertices and m edges admit a routing scheme that has competitive ratio O(log² n) and consists of a convex combination of only O(√m) electrical routings.

They allow to compress the initial dataset while preserving its structure: running any algorithm on the coreset provides a guarantee almost equivalent to running it on the full data. In this work, we study coresets in a fully-dynamic setting: points are added and deleted with the goal to efficiently maintain a coreset with which a k-means solution can be computed. Based on an algorithm from Henzinger and Kale [ESA'20], we present an efficient and practical implementation of a fully dynamic coreset algorithm, that improves the running time by up to a factor of 20 compared to our non-optimized implementation of the algorithm by Henzinger and Kale, without sacrificing more than 7% on the quality of the k-means solution."}],"ec_funded":1,"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"eisbn":["9781611977929"]}},{"_id":"15009","status":"public","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)"},"ddc":["570"],"date_updated":"2024-02-26T09:59:30Z","department":[{"_id":"BeVi"}],"file_date_updated":"2024-02-26T09:54:59Z","pmid":1,"oa_version":"Published Version","abstract":[{"lang":"eng","text":"Since the commercialization of brine shrimp (genus Artemia) in the 1950s, this lineage, and in particular the model species Artemia franciscana, has been the subject of extensive research.

This approximation assumes that the timescale of the laser-molecule interaction is significantly shorter than the internal rotational period of the molecule, resulting in the rotational motion being instantaneously “frozen” during the interaction. This simplified description of the laser-molecule interaction is incorporated in various theoretical models predicting rotational dynamics of molecules driven by short laser pulses. In this theoretical work, we develop an effective theory for ultrashort laser pulses by examining the full time-evolution operator and solving the time-dependent Schrödinger equation at the operator level. Our findings reveal a critical angular momentum, lcrit, at which the impulsive limit breaks down. In other words, the validity of the sudden approximation depends not only on the pulse duration but also on its intensity, since the latter determines how many angular momentum states are populated. We explore both ultrashort multicycle (Gaussian) pulses and the somewhat less studied half-cycle pulses, which produce distinct effective potentials. We discuss the limitations of the impulsive limit and propose a method that rescales the effective matrix elements, enabling an improved and more accurate description of laser-molecule interactions.","lang":"eng"}],"oa_version":"Preprint","scopus_import":"1","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2307.07256","open_access":"1"}],"month":"02","intvolume":" 109","publication_identifier":{"eissn":["2469-9934"],"issn":["2469-9926"]},"publication_status":"published","language":[{"iso":"eng"}],"volume":109,"issue":"2","ec_funded":1},{"has_accepted_license":"1","year":"2024","file":[{"creator":"melkrewi","file_size":847,"date_updated":"2023-12-22T13:54:21Z","file_name":"readme.txt.txt","date_created":"2023-12-22T13:54:21Z","relation":"main_file","access_level":"open_access","content_type":"text/plain","success":1,"file_id":"14707","checksum":"bdaf1392867786634ec5466d528c36ca"},{"date_created":"2023-12-22T14:14:06Z","file_name":"data_artemia_franciscana_genome.zip","creator":"melkrewi","date_updated":"2023-12-22T14:14:06Z","file_size":343632753,"checksum":"973e1cbdab923a71709782177980829f","file_id":"14708","success":1,"access_level":"open_access","relation":"main_file","content_type":"application/x-zip-compressed"}],"day":"02","date_published":"2024-01-02T00:00:00Z","doi":"10.15479/AT:ISTA:14705","related_material":{"record":[{"relation":"used_in_publication","status":"public","id":"15009"}]},"contributor":[{"last_name":"Bett","id":"57854184-AAE0-11E9-8D04-98D6E5697425","first_name":"Vincent K","contributor_type":"researcher"},{"id":"2A0848E2-F248-11E8-B48F-1D18A9856A87","first_name":"Ariana","contributor_type":"project_member","last_name":"Macon"},{"last_name":"Vicoso","orcid":"0000-0002-4579-8306","id":"49E1C5C6-F248-11E8-B48F-1D18A9856A87","contributor_type":"supervisor","first_name":"Beatriz"},{"contributor_type":"researcher","first_name":"Marwan N","id":"0B46FACA-A8E1-11E9-9BD3-79D1E5697425","orcid":"0000-0002-5328-7231","last_name":"Elkrewi"}],"date_created":"2023-12-22T13:40:48Z","abstract":[{"text":"Since the commercialization of brine shrimp (genus Artemia) in the 1950s, this lineage, and in particular the model species Artemia franciscana, has been the subject of extensive research.

The assessment of the layer and the interface qualities for a buried strained Ge layer embedded in Si0.3Ge0.7 layers is reported. The XRD reciprocal space mapping confirmed that the reduction of the growth temperature enables the 2-dimensional growth of the Ge layer fully strained with respect to the Si0.3Ge0.7. Nevertheless, dislocations at the top and/or bottom interface of the Ge layer were observed by means of electron channeling contrast imaging, suggesting the importance of the careful dislocation assessment. The interface abruptness does not depend on the selection of the precursor gases, but it is strongly influenced by the growth temperature which affects the coverage of the surface H-passivation. The mobility of 2.7 × 105 cm2/Vs is promising, while the low percolation density of 3 × 1010 /cm2 measured with a Hall-bar device at 7 K illustrates the high quality of the heterostructure thanks to the high Si0.3Ge0.7 SRB quality.","lang":"eng"}],"oa_version":"Published Version","volume":174,"issue":"5","publication_status":"epub_ahead","publication_identifier":{"issn":["1369-8001"]},"language":[{"iso":"eng"}],"project":[{"_id":"34c0acea-11ca-11ed-8bc3-8775e10fd452","name":"Integrated GermaNIum quanTum tEchnology","grant_number":"101069515"}],"article_number":"108231","article_processing_charge":"No","author":[{"first_name":"Yosuke","full_name":"Shimura, Yosuke","last_name":"Shimura"},{"first_name":"Clement","full_name":"Godfrin, Clement","last_name":"Godfrin"},{"first_name":"Andriy","full_name":"Hikavyy, Andriy","last_name":"Hikavyy"},{"first_name":"Roy","full_name":"Li, Roy","last_name":"Li"},{"id":"2A67C376-F248-11E8-B48F-1D18A9856A87","first_name":"Juan L","last_name":"Aguilera Servin","full_name":"Aguilera Servin, Juan L","orcid":"0000-0002-2862-8372"},{"last_name":"Katsaros","full_name":"Katsaros, Georgios","orcid":"0000-0001-8342-202X","id":"38DB5788-F248-11E8-B48F-1D18A9856A87","first_name":"Georgios"},{"full_name":"Favia, Paola","last_name":"Favia","first_name":"Paola"},{"last_name":"Han","full_name":"Han, Han","first_name":"Han"},{"full_name":"Wan, Danny","last_name":"Wan","first_name":"Danny"},{"full_name":"de Greve, Kristiaan","last_name":"de Greve","first_name":"Kristiaan"},{"full_name":"Loo, Roger","last_name":"Loo","first_name":"Roger"}],"title":"Compressively strained epitaxial Ge layers for quantum computing applications","citation":{"ieee":"Y.
