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"}],"license":"https://creativecommons.org/licenses/by/4.0/","volume":174,"issue":"5","language":[{"iso":"eng"}],"publication_status":"epub_ahead","publication_identifier":{"issn":["1369-8001"]},"keyword":["Mechanical Engineering","Mechanics of Materials","Condensed Matter Physics","General Materials Science"],"status":"public","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","_id":"15018","department":[{"_id":"GeKa"},{"_id":"NanoFab"}],"ddc":["530"],"date_updated":"2024-02-26T10:36:35Z","oa":1,"publisher":"Elsevier","quality_controlled":"1","acknowledgement":"The Ge project received funding from the European Union's Horizon Europe programme under the Grant Agreement 101069515 – IGNITE.

We revisit the question of accurate BERT-pruning during fine-tuning on downstream datasets, and propose a set of general guidelines for successful pruning, even on the challenging SMC benchmark. First, we perform a cost-vs-benefits analysis of pruning model components, such as the embeddings and the classification head; second, we provide a simple-yet-general way of scaling training, sparsification and learning rate schedules relative to the desired target sparsity; finally, we investigate the importance of proper parametrization for Knowledge Distillation in the context of LLMs. Our simple insights lead to state-of-the-art results, both on classic BERT-pruning benchmarks, as well as on the SMC benchmark, showing that even classic gradual magnitude pruning (GMP) can yield competitive results, with the right approach."}],"intvolume":" 234","month":"01","main_file_link":[{"url":"https://proceedings.mlr.press/v234/kurtic24a","open_access":"1"}],"scopus_import":"1","alternative_title":["PMLR"],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"eissn":["2640-3498"]},"volume":234,"_id":"15011","status":"public","conference":{"name":"CPAL: Conference on Parsimony and Learning","start_date":"2024-01-03","end_date":"2024-01-06","location":"Hongkong, China"},"type":"conference","date_updated":"2024-02-26T10:30:52Z","department":[{"_id":"DaAl"}]},{"date_created":"2024-02-25T23:00:55Z","date_published":"2024-02-14T00:00:00Z","doi":"10.1063/5.0188215","publication":"Journal of Chemical Physics","day":"14","year":"2024","has_accepted_license":"1","oa":1,"publisher":"AIP Publishing","quality_controlled":"1","acknowledgement":"The author thanks Lydéric Bocquet, Baptiste Coquinot, and Mathieu Lizée for fruitful discussions.

The effects of these correlations on the solvent itself remain, however, much less clear. In particular, the addition of salt has been consistently reported to affect the solution’s viscosity, but most modeling attempts fail to reproduce experimental data even at moderate salt concentrations. Here, we use an approach based on stochastic density functional theory, which accurately captures charge fluctuations and correlations. We derive a simple analytical expression for the viscosity correction in concentrated electrolytes, by directly linking it to the liquid’s structure factor. Our prediction compares quantitatively to experimental data at all temperatures and all salt concentrations up to the saturation limit. This universal link between the microscopic structure and viscosity allows us to shed light on the nanoscale dynamics of water and ions under highly concentrated and correlated conditions."}],"file_date_updated":"2024-02-27T08:12:52Z","department":[{"_id":"EdHa"}],"ddc":["540"],"date_updated":"2024-02-27T08:16:06Z","status":"public","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","_id":"15024"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"mla":"Erdös, László, and Benjamin McKenna. “Extremal Statistics of Quadratic Forms of GOE/GUE Eigenvectors.” Annals of Applied Probability, vol. 34, no. 1B, Institute of Mathematical Statistics, 2024, pp. 1623–62, doi:10.1214/23-AAP2000.","short":"L.

The current models place GN at the Golgi apparatus (GA), where it mediates secretion/recycling, and at the plasma membrane (PM) presumably contributing to clathrin-mediated endocytosis (CME). The mechanistic basis of the developmental function of GN, distinct from the other ARF-GEFs including its closest homologue GNOM-LIKE1 (GNL1), remains elusive. Insights from this study largely extend the current notions of GN function. We show that GN, but not GNL1, localizes to the cell periphery at long-lived structures distinct from clathrin-coated pits, while CME and secretion proceed normally in gn knockouts. The functional GN mutant variant GNfewerroots, absent from the GA, suggests that the cell periphery is the major site of GN action responsible for its developmental function. Following inhibition by Brefeldin A, GN, but not GNL1, relocates to the PM likely on exocytic vesicles, suggesting selective molecular associations en route to the cell periphery. A study of GN-GNL1 chimeric ARF-GEFs indicates that all GN domains contribute to the specific GN function in a partially redundant manner. Together, this study offers significant steps toward the elucidation of the mechanism underlying unique cellular and development functions of GNOM."}],"oa_version":"Published Version","ec_funded":1,"volume":13,"publication_status":"epub_ahead","publication_identifier":{"issn":["2050-084X"]},"language":[{"iso":"eng"}],"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)"},"type":"journal_article","article_type":"original","keyword":["General Immunology and Microbiology","General Biochemistry","Genetics and Molecular Biology","General Medicine","General Neuroscience"],"status":"public","_id":"15033","department":[{"_id":"JiFr"}],"date_updated":"2024-02-28T12:29:43Z","ddc":["580"]}]
