The heliocentric orbit and approximate absolute magnitude of Dinkinesh are known, but little additional information was available prior to its selection as a target. In particular, the lack of color spectrophotometry or spectra made it impossible to assign a spectral type to Dinkinesh from which its albedo could be estimated. We set out to remedy this knowledge gap by obtaining visible wavelength spectra with the Keck telescope on 2022 November 23 and with Gemini-South on 2022 December 27. The spectra measured with the Keck I/Low Resolution Imaging Spectrometer (LRIS) and the Gemini South/Gemini Multi-Object Spectrograph South (GMOS-S) are most similar to the average spectrum of S- and Sq-type asteroids. The most diagnostic feature is the ≈15 ± 1% silicate absorption feature at ≈0.9–1.0 μm. Small S- and Sq-type asteroids have moderately high albedos ranging from 0.17 to 0.35. Using this albedo range for Dinkinesh in combination with measured absolute magnitude, it is possible to derive an effective diameter and surface brightness for this body. The albedo, size and surface brightness are important inputs required for planning a successful encounter by the Lucy spacecraft.","lang":"eng"}],"author":[{"first_name":"B.T.","last_name":"Bolin","full_name":"Bolin, B.T."},{"first_name":"K.S.","last_name":"Noll","full_name":"Noll, K.S."},{"full_name":"Caiazzo, Ilaria","last_name":"Caiazzo","orcid":"0000-0002-4770-5388","id":"8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d","first_name":"Ilaria"},{"first_name":"C.","full_name":"Fremling, C.","last_name":"Fremling"},{"last_name":"Binzel","full_name":"Binzel, R.P.","first_name":"R.P."}],"title":"Keck and Gemini spectral characterization of Lucy mission fly-by target (152830) Dinkinesh","day":"07","year":"2023","quality_controlled":"1","external_id":{"arxiv":["2303.08130"]},"extern":"1","article_type":"original","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"oa":1,"date_published":"2023-04-07T00:00:00Z","doi":"10.1016/j.icarus.2023.115562","publisher":"Elsevier","language":[{"iso":"eng"}],"citation":{"mla":"Bolin, B.

As the velocity dispersion of stars in the local disc increases with age, a proposed explanation of these white dwarfs is that they experience a cooling delay that causes current cooling models to infer photometric ages much younger than their true ages. To explore this explanation, we investigate the kinematics of ultramassive white dwarfs within 200 pc of the Sun using the improved Gaia Early Data Release 3 observations. We analyse the transverse motions of 0.95–1.25 M⊙ white dwarfs, subdivided by mass and age, and determine the distributions of the three-dimensional components of the transverse velocities. The results are compared to expectations based on observed kinematics of local main-sequence stars. We find a population of photometrically young (∼0.5–1.5 Gyr) ultramassive (∼1.15–1.25 M⊙) white dwarfs for which the transverse velocity component in the direction of Galactic rotation is more dispersed than for local disc stars of any age; thus, it is too dispersed to be explained by any cooling delay in white dwarfs originating from the local disc. Furthermore, the dispersion ratio of the velocity components in the Galactic plane for this population is also inconsistent with a local disc origin. We discuss some possible explanations of this kinematically anomalous population, such as a halo origin or production through dynamical effects of stellar triple systems.","lang":"eng"}],"intvolume":"       520","date_updated":"2024-04-02T07:13:10Z","oa_version":"Preprint","author":[{"first_name":"Leesa","full_name":"Fleury, Leesa","last_name":"Fleury"},{"last_name":"Caiazzo","full_name":"Caiazzo, Ilaria","first_name":"Ilaria","id":"8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d","orcid":"0000-0002-4770-5388"},{"first_name":"Jeremy","full_name":"Heyl, Jeremy","last_name":"Heyl"}],"article_processing_charge":"No","status":"public","date_created":"2024-03-26T09:48:27Z","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2205.01015"}],"publication":"Monthly Notices of the Royal Astronomical Society","publication_identifier":{"issn":["0035-8711"],"eissn":["1365-2966"]},"_id":"15199","scopus_import":"1","month":"01","arxiv":1,"volume":520,"type":"journal_article","citation":{"chicago":"Fleury, Leesa, Ilaria Caiazzo, and Jeremy Heyl. “The Origin of Ultramassive White Dwarfs: Hints from <i>Gaia</i> EDR3.” <i>Monthly Notices of the Royal Astronomical Society</i>.

We apply the unbinned technique to models of the luminous X-ray pulsar Hercules X-1, for which we produce simulated observations using the IXPEOBSSIM package. We consider minimal knowledge about the actual physical process responsible for the polarized emission from the accreting pulsar and assume that the observed phase-dependent polarization angle can be described by the rotating vector model. Using the unbinned technique, the detector’s modulation factor, and the polarization information alone, we found that both the rotating vector model and the underlying spectro-polarimetry model can reconstruct equally well the geometric configuration angles of the accreting pulsar. However, the measured polarization fraction becomes biased with respect to the underlying model unless the energy dispersion and effective area of the detector are also taken into account. To this end, we present an energy-dispersed likelihood estimator that is proved to be unbiased. For different analyses, we obtain posterior distributions from multiple IXPEOBSSIM realizations and show that the unbinned technique yields \r\n smaller error bars than the binned technique. We also discuss alternative sources, such as magnetars, in which the unbinned technique and the rotating vector model might be applied."}],"title":"Unbinned likelihood analysis for X-ray polarization","day":"16","publication_identifier":{"eissn":["1365-2966"],"issn":["0035-8711"]},"publication":"Monthly Notices of the Royal Astronomical Society","main_file_link":[{"url":"https://arxiv.org/abs/2204.00140","open_access":"1"}],"date_created":"2024-03-26T09:49:52Z","status":"public","article_processing_charge":"No"},{"oa":1,"publisher":"American Astronomical Society","date_published":"2023-02-15T00:00:00Z","doi":"10.3847/2041-8213/acb703","language":[{"iso":"eng"}],"issue":"2","article_type":"original","extern":"1","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"external_id":{"arxiv":["2301.12919"]},"quality_controlled":"1","year":"2023","arxiv":1,"scopus_import":"1","month":"02","_id":"15202","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","citation":{"ieee":"S.

measurements. We present here the first Imaging X-ray Polarimetry Explorer observation of the magnetar 1RXS J170849.0-400910, jointly analyzed with a new Swift observation and archival NICER data. The total (energy- and phase-integrated) emission in the 2–8 keV energy range is linerarly polarized, at a ∼35% level. The phase-averaged polarization signal shows a marked increase with energy, ranging from ∼20% at 2–3 keV up to ∼80% at 6–8 keV, while the polarization angle remains constant. This indicates that radiation is mostly polarized in a single direction. The spectrum is well reproduced by a combination of either two thermal (blackbody) components or a blackbody and a power law. Both the polarization degree and angle also show a variation with the spin phase, and the former is almost anticorrelated with the source counts in the 2–8 and 2–4 keV bands. We discuss the possible implications and interpretations, based on a joint analysis of the spectral, polarization, and pulsation properties of the source. A scenario in which the surface temperature is not homogeneous, with a hotter cap covered by a gaseous atmosphere and a warmer region in a condensed state, provides a satisfactory description of both the phase- and energy-dependent spectro-polarimetric data. The (comparatively) small size of the two emitting regions, required to explain the observed pulsations, does not allow to reach a robust conclusion about the presence of vacuum birefringence effects."}]},{"article_processing_charge":"No","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1017/S1743921322000916"}],"date_created":"2024-03-26T10:35:20Z","status":"public","publication":"Proceedings of the International Astronomical Union","publication_identifier":{"eissn":["1743-9221"],"issn":["1743-9213"]},"title":"X-ray polarization at the crossroads","day":"27","oa_version":"Published Version","intvolume":"        16","date_updated":"2024-04-04T09:46:17Z","abstract":[{"lang":"eng","text":"We argue that measurements of X-ray polarization using the recently launched Imaging X-ray Polarimetry Explorer will answer many open questions about magnetars in particular the physical state of their surfaces, whether vacuum birefringence exists, and the nature of the hard X-ray emission from these objects.

I will discuss future prospect to discriminate between different magnetar’s emission mechanisms, as well as a potential detection of the signal of vacuum birefringence using IXPE.\r\n\r\n"}],"intvolume":"        16","date_updated":"2024-04-04T12:54:59Z","oa_version":"Published Version","author":[{"first_name":"Denis","last_name":"González-Caniulef","full_name":"González-Caniulef, Denis"},{"last_name":"Caiazzo","full_name":"Caiazzo, Ilaria","id":"8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d","first_name":"Ilaria","orcid":"0000-0002-4770-5388"},{"full_name":"Heyl, Jeremy","last_name":"Heyl","first_name":"Jeremy"}],"day":"27","title":"IXPE simulations for magnetars"},{"year":"2023","publisher":"ACM","language":[{"iso":"eng"}],"date_published":"2023-08-01T00:00:00Z","doi":"10.1145/3606037.3606836","file":[{"content_type":"video/mp4","date_updated":"2024-04-03T14:58:24Z","file_size":58770929,"file_id":"15293","file_name":"video.mp4","access_level":"open_access","checksum":"88bdef929ca262ee0eefae0bbc649139","relation":"main_file","creator":"yichen","success":1,"date_created":"2024-04-03T14:58:24Z"},{"date_created":"2024-04-03T14:58:23Z","relation":"main_file","creator":"yichen","success":1,"file_id":"15294","file_name":"frictionPoster_clean.pdf","checksum":"c06881ba847da365a74ac09c953eaffd","access_level":"open_access","content_type":"application/pdf","date_updated":"2024-04-03T14:58:23Z","file_size":3951968}],"oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","corr_author":"1","type":"conference_poster","publication_status":"published","citation":{"apa":"Chen, Y.-L., Ly, M., &#38; Wojtan, C.

Despite its apparent simplicity, the underlying mechanics behind knowledge distillation (KD) are not yet fully understood. In this work, we shed new light on the inner workings of this method, by examining it from an optimization perspective. Specifically, we show that, in the context of linear and deep linear models, KD can be interpreted as a novel type of stochastic variance reduction mechanism. We provide a detailed convergence analysis of the resulting dynamics, which hold under standard assumptions for both strongly-convex and non-convex losses, showing that KD acts as a form of \\emph{partial variance reduction}, which can reduce the stochastic gradient noise, but may not eliminate it completely, depending on the properties of the teacher'' model. Our analysis puts further emphasis on the need for careful parametrization of KD, in particular w.r.t. the weighting of the distillation loss, and is validated empirically on both linear models and deep neural networks."}],"oa_version":"Published Version","intvolume":"        36","date_updated":"2025-04-14T07:54:55Z","ddc":["000"],"day":"15","alternative_title":["NeurIPS"],"title":"Knowledge distillation performs partial variance reduction","department":[{"_id":"DaAl"}],"project":[{"name":"IST-BRIDGE: International postdoctoral program","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","grant_number":"101034413","call_identifier":"H2020"}],"has_accepted_license":"1","publication_identifier":{"issn":["1049-5258"]},"ec_funded":1,"conference":{"start_date":"2023-12-10","location":"New Orleans, LA, United States","name":"NeurIPS: Neural Information Processing Systems","end_date":"2023-12-16"},"publication":"36th Conference on Neural Information Processing Systems","acknowledgement":"MS has received funding from the European Union’s Horizon 2020 research and innovation programme\r\nunder the Marie Skłodowska-Curie grant agreement No 101034413.","date_created":"2024-05-05T22:01:04Z","status":"public","file_date_updated":"2024-05-22T08:08:08Z","article_processing_charge":"Yes"},{"status":"public","file_date_updated":"2024-05-22T07:34:00Z","date_created":"2024-05-05T22:01:05Z","acknowledgement":"Moses Charikar was supported by a Simons Investigator award.

Popular clustering algorithms such as Lloyd's algorithm and k-means++ can make Ω(ndk) time when clustering n points in a d-dimensional space (represented by an n×d matrix X) into k clusters. On massive datasets with moderate to large k, the multiplicative \r\nk factor can become very expensive. We introduce a simple randomized clustering algorithm that provably runs in expected time O(nnz(X)+nlogn) for arbitrary k. Here nnz(X) is the total number of non-zero entries in the input dataset X, which is upper bounded by nd and can be significantly smaller for sparse datasets. We prove that our algorithm achieves approximation ratio ˜O(k4) on any input dataset for the k-means objective, and our experiments show that the quality of the clusters found by our algorithm is usually much better than this worst-case bound. We use our algorithm for k-means clustering and for coreset construction; our experiments show that it gives a new tradeoff between running time and cluster quality compared to previous state-of-the-art methods for these tasks. Our theoretical analysis is based on novel results of independent interest. We show that the approximation ratio achieved after a random one-dimensional projection can be lifted to the original points and that k-means++ seeding can be implemented in expected time O(nlogn) in one dimension."}],"oa":1,"file":[{"file_name":"2023_Neurips_Charikar.pdf","access_level":"open_access","checksum":"d169a147a2adf55878e0a99e36a9d468","file_id":"15416","file_size":1445159,"content_type":"application/pdf","date_updated":"2024-05-22T07:34:00Z","date_created":"2024-05-22T07:34:00Z","success":1,"relation":"main_file","creator":"dernst"}],"language":[{"iso":"eng"}],"date_published":"2023-12-15T00:00:00Z","external_id":{"arxiv":["2310.16752"]},"year":"2023","quality_controlled":"1","arxiv":1,"month":"12","scopus_import":"1","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"_id":"15364","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"short":"M.

We found that in alkaline, drying conditions in bulk and at heated air‐water interfaces, 2′,3′‐cyclic nucleotides oligomerised without additional catalyst, forming up to 10‐mers within a day. The oligomerisation proceeded at a pH range of 7–12, at temperatures between 40–80 °C and was marginally enhanced by K<jats:sup>+</jats:sup> ions. Among the canonical ribonucleotides, cGMP oligomerised most efficiently. Quantification was performed using HPLC coupled to ESI‐TOF by fitting the isotope distribution to the mass spectra. Our study suggests a oligomerisation mechanism where cGMP aids the incorporation of the relatively unreactive nucleotides C, A and U. The 2′,3′‐cyclic ribonucleotides are byproducts of prebiotic phosphorylation, nucleotide syntheses and RNA hydrolysis, indicating direct recycling pathways. The simple reaction condition offers a plausible entry point for RNA to the evolution of life on early Earth.","lang":"eng"}],"license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","author":[{"first_name":"Avinash Vicholous","last_name":"Dass","full_name":"Dass, Avinash Vicholous"},{"first_name":"Sreekar","last_name":"Wunnava","full_name":"Wunnava, Sreekar"},{"first_name":"Juliette","full_name":"Langlais, Juliette","last_name":"Langlais"},{"full_name":"von der Esch, Beatriz","last_name":"von der Esch","first_name":"Beatriz"},{"first_name":"Maik","last_name":"Krusche","full_name":"Krusche, Maik"},{"first_name":"Lennard","full_name":"Ufer, Lennard","last_name":"Ufer"},{"last_name":"Chrisam","full_name":"Chrisam, Nico","first_name":"Nico"},{"full_name":"Dubini, Romeo C.

A gambler is sent values online, sampled from an instance of independent distributions, in an adversarial, random or selected order, depending on the model. When observing each value, the gambler either accepts it as a reward or irrevocably rejects it and proceeds to observe the next value. The goal of the gambler, who cannot see the future, is maximising the expected value of the reward while competing against the expectation of a prophet (the offline maximum). In other words, one seeks to maximise the gambler-to-prophet ratio of the expectations.\r\nThe model, in which the gambler selects the arrival order first, and then observes the values, is known as Order Selection. In this model a ratio of 0.7251 has been proved to be attainable for any instance. In very recent work, this has been improved up to 0.7258. If the gambler chooses the arrival order (uniformly) at random, we obtain the Random Order model. The worst case ratio over all possible instances has been extensively studied for at least 40 years. In the recent work aforementioned, through simulations, this ratio has been shown to be at most 0.7254 for the Random Order model, thus establishing for the first time that carefully choosing the order, instead of simply taking it at random, benefits the gambler. We give an alternative, more rigorous proof of this fact, by showing mathematically that in the Random Order model, no algorithm can achieve a ratio larger than 0.7235. This sets a new state-of-the-art hardness for this model, and establishes more formally that there is a real benefit in choosing the order."}],"type":"preprint","title":"Prophet inequalities: Separating random order from order selection","arxiv":1,"day":"08","month":"04","_id":"17100","department":[{"_id":"KrCh"}],"project":[{"_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020","grant_number":"863818","name":"Formal Methods for Stochastic Models: Algorithms and Applications"}],"ec_funded":1,"external_id":{"arxiv":["2304.04024"]},"year":"2023","publication":"arXiv","date_created":"2024-06-03T07:44:54Z","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2304.04024","open_access":"1"}],"status":"public","oa":1,"date_published":"2023-04-08T00:00:00Z","doi":"10.48550/arXiv.2304.04024","language":[{"iso":"eng"}],"acknowledgement":"This research was partially supported by the EPSRC grant EP/W005573/1, the ERC CoG 863818 (ForM-SMArt) grant, and the ANID Chile grant ACT210005.

This function is mediated by conserved cell adhesion molecules, which are tightly regulated to allow for coordinated neuronal outgrowth. Here, we show that the proprotein convertase KPC-1 (homolog of mammalian furin) regulates the Menorin adhesion complex during development of PVD dendritic arbors in Caenorhabditis elegans. We found a finely regulated antagonistic balance between PVD-expressed KPC-1 and the epidermally expressed putative cell adhesion molecule MNR-1 (Menorin). Genetically, partial loss of mnr-1 suppressed partial loss of kpc-1, and both loss of kpc-1 and transgenic overexpression of mnr-1 resulted in indistinguishable phenotypes in PVD dendrites. This balance regulated cell-surface localization of the DMA-1 leucine-rich transmembrane receptor in PVD neurons. Lastly, kpc-1 mutants showed increased amounts of MNR-1 and decreased amounts of muscle-derived LECT-2 (Chondromodulin II), which is also part of the Menorin adhesion complex. These observations suggest that KPC-1 in PVD neurons directly or indirectly controls the abundance of proteins of the Menorin adhesion complex from adjacent tissues, thereby providing negative feedback from the dendrite to the instructive cues of surrounding tissues."}],"title":"Convertase-dependent regulation of membrane-tethered and secreted ligands tunes dendrite adhesion","ddc":["570"],"day":"18","OA_type":"hybrid","has_accepted_license":"1"},{"ddc":["550"],"day":"05","month":"06","title":"A 3D glacier dynamics-line plume model to estimate the frontal ablation of Hansbreen","department":[{"_id":"FrPe"}],"_id":"18634","author":[{"first_name":"José M","id":"e1037a6d-646e-11ef-b402-e0ed9ab0901e","full_name":"Muñoz Hermosilla, José M","last_name":"Muñoz Hermosilla"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","OA_place":"repository","type":"research_data_reference","corr_author":"1","abstract":[{"text":"There are 4 tar.xz files with the result of the model for the paper: A 3D glacier dynamics-line plume model to estimate the frontal ablation of Hansbreen, Svalbard.

Primarily sites of photosynthesis, chloroplasts are unique sites also for the biosynthesis of precursors of the growth regulator auxin and for sensing environmental stress, but their role in intracellular auxin homeostasis, vital for plant growth and survival in changing environments, remains poorly understood. Here, we identified two ATP-binding cassette (ABC) subfamily B transporters, ABCB28 and ABCB29, which export auxin across the chloroplast envelope to the cytosol in a concerted action in vivo. Moreover, we provide evidence for an auxin biosynthesis pathway in Arabidopsis thaliana chloroplasts. The overexpression of ABCB28 and ABCB29 influenced stomatal regulation and resulted in significantly improved water use efficiency and survival rates during salt and drought stresses. Our results suggest that chloroplast auxin production and transport contribute to stomata regulation for conserving water upon salt stress. ABCB28 and ABCB29 integrate photosynthesis and auxin signals and as such hold great potential to improve the adaptation potential of crops to environmental cues.","lang":"eng"}],"article_number":"7","oa_version":"Published Version","intvolume":"        13","date_updated":"2025-01-29T09:07:53Z","ddc":["580"],"day":"19","title":"Chloroplast auxin efflux mediated by ABCB28 and ABCB29 fine-tunes salt and drought stress responses in Arabidopsis","department":[{"_id":"EvBe"}],"OA_type":"gold","has_accepted_license":"1"}]
