Coresets are one the main tools developed recently to solve this problem in a big data context. 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."}],"oa_version":"Preprint","department":[{"_id":"MoHe"}],"date_updated":"2024-02-26T09:51:31Z","type":"conference","conference":{"location":"Alexandria, VA, United States","end_date":"2024-01-08","start_date":"2024-01-07","name":"ALENEX: Workshop on Algorithm Engineering and Experiments"},"status":"public","_id":"14769","page":"220-233","doi":"10.1137/1.9781611977929.17","date_published":"2024-01-04T00:00:00Z","date_created":"2024-01-09T16:22:47Z","year":"2024","day":"04","publication":"2024 Proceedings of the Symposium on Algorithm Engineering and Experiments","quality_controlled":"1","publisher":"Society for Industrial & Applied Mathematics","oa":1,"acknowledgement":"This project has received funding from the Euro-pean Research Council (ERC) under the EuropeanUnion’s Horizon 2020 research and innovation programme (Grant agreement No. 101019564 “The De-sign of Modern Fully Dynamic Data Structures (Mo-DynStruct)” and the Austrian Science Fund (FWF)project Z 422-N, project “Static and Dynamic Hierar-chical Graph Decompositions”, I 5982-N, and project“Fast Algorithms for a Reactive Network Layer (Re-actNet)”, P 33775-N, with additional funding from thenetidee SCIENCE Stiftung, 2020–2024.D.

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."}]},{"_id":"14705","status":"public","project":[{"name":"The highjacking of meiosis for asexual reproduction","grant_number":"F8810","_id":"34ae1506-11ca-11ed-8bc3-c14f4c474396"}],"keyword":["sex chromosome evolution","genome assembly","dosage compensation"],"type":"research_data","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":["576"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ama":"Elkrewi MN.

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","department":[{"_id":"GeKa"},{"_id":"NanoFab"}],"date_updated":"2024-02-26T10:36:35Z","ddc":["530"],"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)"},"article_type":"original","type":"journal_article","keyword":["Mechanical Engineering","Mechanics of Materials","Condensed Matter Physics","General Materials Science"],"status":"public","_id":"15018"}]
