Under the assumptions of stationarity and ergodicity, we characterize the Gamma-limit of a micromagnetic energy functional defined on magnetizations taking value in the unit sphere and including both symmetric and antisymmetric exchange contributions. This Gamma-limit corresponds to a micromagnetic energy functional with homogeneous coefficients. We provide explicit formulas for the effective magnetic properties of the composite material in terms of homogenization correctors. Additionally, the variational analysis of the two exchange energy terms is performed in the more general setting of functionals defined on manifold-valued maps with Sobolev regularity, in the case in which the target manifold is a bounded, orientable smooth surface with tubular neighborhood of uniform thickness. Eventually, we present an explicit characterization of minimizers of the effective exchange in the case of magnetic multilayers, providing quantitative evidence of Dzyaloshinskii’s predictions on the emergence of helical structures in composite ferromagnetic materials with stochastic microstructure."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"14884","intvolume":" 34","status":"public","title":"Stochastic homogenization of micromagnetic energies and emergence of magnetic skyrmions","oa_version":"Preprint"},{"intvolume":" 25","ddc":["570"],"status":"public","title":"Ana1/CEP295 is an essential player in the centrosome maintenance program regulated by Polo kinase and the PCM","_id":"14933","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"Published Version","file":[{"file_name":"2023_EmboReports_PimentaMarques.pdf","access_level":"open_access","creator":"dernst","file_size":9645056,"content_type":"application/pdf","file_id":"14941","relation":"main_file","date_created":"2024-02-05T12:35:03Z","date_updated":"2024-02-05T12:35:03Z","success":1,"checksum":"53c3ef43d9bd6d7bff3ffcf57d763cac"}],"type":"journal_article","issue":"1","abstract":[{"text":"Centrioles are part of centrosomes and cilia, which are microtubule organising centres (MTOC) with diverse functions. Despite their stability, centrioles can disappear during differentiation, such as in oocytes, but little is known about the regulation of their structural integrity. Our previous research revealed that the pericentriolar material (PCM) that surrounds centrioles and its recruiter, Polo kinase, are downregulated in oogenesis and sufficient for maintaining both centrosome structural integrity and MTOC activity. We now show that the expression of specific components of the centriole cartwheel and wall, including ANA1/CEP295, is essential for maintaining centrosome integrity. We find that Polo kinase requires ANA1 to promote centriole stability in cultured cells and eggs. In addition, ANA1 expression prevents the loss of centrioles observed upon PCM-downregulation. However, the centrioles maintained by overexpressing and tethering ANA1 are inactive, unlike the MTOCs observed upon tethering Polo kinase. These findings demonstrate that several centriole components are needed to maintain centrosome structure. Our study also highlights that centrioles are more dynamic than previously believed, with their structural stability relying on the continuous expression of multiple components.","lang":"eng"}],"page":"102-127","article_type":"original","citation":{"chicago":"Pimenta-Marques, Ana, Tania Perestrelo, Patricia Dos Reis Rodrigues, Paulo Duarte, Ana Ferreira-Silva, Mariana Lince-Faria, and Mónica Bettencourt-Dias. “Ana1/CEP295 Is an Essential Player in the Centrosome Maintenance Program Regulated by Polo Kinase and the PCM.” EMBO Reports.

In the 1970s, Stephen Jay Gould presented the first extensive data on antler size in the Irish elk and combined these with comparative data from other deer to test the hypothesis that the gigantic antlers were the outcome of a positive allometry that constrained large-bodied deer to have proportionally even larger antlers. He concluded that the Irish elk had antlers as predicted for its size and interpreted this within his emerging framework of developmental constraints as an explanatory factor in evolution. Here we reanalyze antler allometry based on new morphometric data for 57 taxa of the family Cervidae. We also present a new phylogeny for the Cervidae, which we use for comparative analyses. In contrast to Gould, we find that the antlers of Irish elk were larger than predicted from the allometry within the true deer, Cervini, as analyzed by Gould, but follow the allometry across Cervidae as a whole. After dissecting the discrepancy, we reject the allometric-constraint hypothesis because, contrary to Gould, we find no similarity between static and evolutionary allometries, and because we document extensive non-allometric evolution of antler size across the Cervidae."}],"type":"journal_article","language":[{"iso":"eng"}],"date_published":"2024-01-29T00:00:00Z","doi":"10.1007/s11692-023-09624-1","article_type":"original","quality_controlled":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1007/s11692-023-09624-1"}],"oa":1,"citation":{"ama":"Tsuboi M, Kopperud BT, Matschiner M, et al.

The fundamental processes are conceptually well understood, though the magnitudes of cooling and presence of glacier winds are poorly quantified in space and time, increasing the forcing uncertainty for melt models. We utilize a new data set of on-glacier meteorological measurements on three neighboring glaciers in the Swiss Alps to explore their distinct response to regional climate under the extreme 2022 summer. We find that synoptic wind origins and local terrain modifications, not only glacier size, play an important role in the ability of a glacier to cool the near-surface air. Warm air intrusions from valley or synoptically-driven winds onto the glacier can occur between ∼19% and 64% of the time and contribute between 3% and 81% of the total sensible heat flux to the surface during warm afternoon hours, depending on the fetch of the glacier flowline and its susceptibility to boundary layer erosion. In the context of extreme summer warmth, indicative of future conditions, the boundary layer cooling (up to 6.5°C cooler than its surroundings) and resultant katabatic wind flow are highly heterogeneous between the study glaciers, highlighting the complex and likely non-linear response of glaciers to an uncertain future."}],"issue":"2","type":"journal_article","date_published":"2024-01-28T00:00:00Z","publication":"Journal of Geophysical Research: Atmospheres","citation":{"ista":"Shaw T, Buri P, McCarthy M, Miles ES, Pellicciotti F. 2024.

In High Mountain Asia (HMA), where a wide range of climates from semi-arid to monsoonal exist, the importance of the cryospheric contributions to the water budget varies with the amount and seasonal distribution of precipitation. Losses due to evapotranspiration and sublimation are to date largely unquantified components of the water budget in such catchments, although they can be comparable in magnitude to glacier melt contributions to streamflow. 
Here, we simulate the hydrology of three high elevation headwater catchments in distinct climates in HMA over 10 years using an ecohydrological model geared towards high-mountain areas including snow and glaciers, forced with reanalysis data. 
Our results show that evapotranspiration and sublimation together are most important at the semi-arid site, Kyzylsu, on the northernmost slopes of the Pamir mountain range. Here, the evaporative loss amounts to 28% of the water throughput, which we define as the total water added to, or removed from the water balance within a year. In comparison, evaporative losses are 19% at the Central Himalayan site Langtang and 13% at the wettest site, 24K, on the Southeastern Tibetan Plateau. At the three sites, respectively, sublimation removes 15%, 13% and 6% of snowfall, while evapotranspiration removes the equivalent of 76%, 28% and 19% of rainfall. In absolute terms, and across a comparable elevation range, the highest ET flux is 413 mm yr-1 at 24K, while the highest sublimation flux is 91 mm yr-1 at Kyzylsu. During warm and dry years, glacier melt was found to only partially compensate for the annual supply deficit.","lang":"eng"}],"quality_controlled":"1","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"main_file_link":[{"url":"https://doi.org/10.1088/1748-9326/ad25a0","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"10.1088/1748-9326/ad25a0","month":"02","publication_identifier":{"issn":["1748-9326"]},"publication_status":"accepted","department":[{"_id":"FrPe"}],"publisher":"IOP Publishing","year":"2024","date_created":"2024-02-05T09:01:11Z","date_updated":"2024-02-06T08:35:39Z","author":[{"full_name":"Fugger, Stefan","first_name":"Stefan","last_name":"Fugger","id":"86698d64-c4c6-11ee-af02-cdf1e6a7d31f"},{"first_name":"Thomas","last_name":"Shaw","id":"3caa3f91-1f03-11ee-96ce-e0e553054d6e","orcid":"0000-0001-7640-6152","full_name":"Shaw, Thomas"},{"first_name":"Achille","last_name":"Jouberton","full_name":"Jouberton, Achille"},{"full_name":"Miles, Evan","last_name":"Miles","first_name":"Evan"},{"full_name":"Buri, Pascal","last_name":"Buri","first_name":"Pascal","id":"317987aa-9421-11ee-ac5a-b941b041abba"},{"last_name":"McCarthy","first_name":"Michael","id":"22a2674a-61ce-11ee-94b5-d18813baf16f","full_name":"McCarthy, Michael"},{"full_name":"Fyffe, Catriona Louise","id":"001b0422-8d15-11ed-bc51-cab6c037a228","last_name":"Fyffe","first_name":"Catriona Louise"},{"first_name":"Simone","last_name":"Fatichi","full_name":"Fatichi, Simone"},{"first_name":"Marin","last_name":"Kneib","full_name":"Kneib, Marin"},{"last_name":"Molnar","first_name":"Peter","full_name":"Molnar, Peter"},{"full_name":"Pellicciotti, Francesca","id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","orcid":"0000-0002-5554-8087","first_name":"Francesca","last_name":"Pellicciotti"}]},{"date_created":"2023-08-22T14:19:59Z","date_updated":"2024-02-12T08:56:23Z","oa_version":"Published Version","file":[{"file_id":"14978","relation":"main_file","date_updated":"2024-02-12T08:40:36Z","date_created":"2024-02-12T08:40:36Z","success":1,"checksum":"8fad894c34f1b3d5a14fb8ffb12f7277","file_name":"2024_CPAL_Lao.pdf","access_level":"open_access","creator":"dernst","file_size":8038511,"content_type":"application/pdf"}],"author":[{"first_name":"Dong","last_name":"Lao","full_name":"Lao, Dong"},{"last_name":"Hu","first_name":"Zhengyang","full_name":"Hu, Zhengyang"},{"full_name":"Locatello, Francesco","id":"26cfd52f-2483-11ee-8040-88983bcc06d4","orcid":"0000-0002-4850-0683","first_name":"Francesco","last_name":"Locatello"},{"full_name":"Yang, Yanchao","first_name":"Yanchao","last_name":"Yang"},{"last_name":"Soatto","first_name":"Stefano","full_name":"Soatto, Stefano"}],"status":"public","title":"Divided attention: Unsupervised multi-object discovery with contextually separated slots","ddc":["000"],"publication_status":"published","department":[{"_id":"FrLo"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"14213","year":"2024","abstract":[{"lang":"eng","text":"We introduce a method to segment the visual field into independently moving regions, trained with no ground truth or supervision. It consists of an adversarial conditional encoder-decoder architecture based on Slot Attention, modified to use the image as context to decode optical flow without attempting to reconstruct the image itself. In the resulting multi-modal representation, one modality (flow) feeds the encoder to produce separate latent codes (slots), whereas the other modality (image) conditions the decoder to generate the first (flow) from the slots. This design frees the representation from having to encode complex nuisance variability in the image due to, for instance, illumination and reflectance properties of the scene. Since customary autoencoding based on minimizing the reconstruction error does not preclude the entire flow from being encoded into a single slot, we modify the loss to an adversarial criterion based on Contextual Information Separation. The resulting min-max optimization fosters the separation of objects and their assignment to different attention slots, leading to Divided Attention, or DivA. DivA outperforms recent unsupervised multi-object motion segmentation methods while tripling run-time speed up to 104FPS and reducing the performance gap from supervised methods to 12% or less. DivA can handle different numbers of objects and different image sizes at training and test time, is invariant to permutation of object labels, and does not require explicit regularization."}],"file_date_updated":"2024-02-12T08:40:36Z","type":"conference","language":[{"iso":"eng"}],"conference":{"location":"Hong Kong, China","start_date":"2024-01-03","end_date":"2024-01-03","name":"CPAL: Conference on Parsimony and Learning"},"date_published":"2024-01-03T00:00:00Z","quality_controlled":"1","publication":"1st Conference on Parsimony and Learning","external_id":{"arxiv":["2304.01430"]},"citation":{"chicago":"Lao, Dong, Zhengyang Hu, Francesco Locatello, Yanchao Yang, and Stefano Soatto. “Divided Attention: Unsupervised Multi-Object Discovery with Contextually Separated Slots.” In 1st Conference on Parsimony and Learning, 2024.","mla":"Lao, Dong, et al. “Divided Attention: Unsupervised Multi-Object Discovery with Contextually Separated Slots.” 1st Conference on Parsimony and Learning, 2024.","short":"D.

Torsional oscillators present an opportunity in this regard due to their remarked isolation from environmental noise. For torsional motion, an effective employment of optical cavities to enhance optomechanical interactions—as already established for linear oscillators—so far faced certain challenges. Here, we propose a concept for sensing and manipulating torsional motion, where exclusively the torsional rotations of a pendulum are mapped onto the path length of a single two-mirror optical cavity. The concept inherently alleviates many limitations of previous approaches. A proof-of-principle experiment is conducted with a rigidly controlled pendulum to explore the sensing aspects of the concept and to identify practical limitations in a potential state-of-the art setup. Based on this study, we anticipate development of precision torque sensors utilizing torsional pendulums that can support sensitivities below 10−19Nm/√Hz, while the motion of the pendulums are dominated by quantum radiation pressure noise at sub-microwatts of incoming laser power. These developments will provide horizons for experiments at the interface of quantum mechanics and gravity."}]}]
