In this study, FeCoNiMoW HEAs are synthesized into either amorphous nanosheets (HEANS) or crystalline nanoparticles (HEANP), which are then used to catalyze the lithium–sulfur (Li–S) reaction of Li–S batteries (LSBs). Evaluations in symmetric cells, coin cells, and pouch cells reveal that HEANS significantly enhance LSB performance, achieving initial discharge capacities up to 1632 mAh g−1. The batteries also exhibit excellent cycling stability over 1000 cycles at 3Cand maintain high-rate performance up to 10C with a capacity of 614 mAh g−1. Comprehensive in situ analyses and density functional theory calculations demonstrate that amorphous HEANS provide more active sites, better ionic conductivity and stronger chemical interactions with lithium polysulfides (LiPS). These properties effectively suppress the shuttle effect, promote the complete S8 → Li2S conversion by reducing the impedance of the solid-electrolyte interphase, and accelerate the Li2S4 → Li2S2 step by lowering the nucleation energy barrier. Overall, this study highlights the superior catalytic properties of amorphous 2D HEAs in LSBs and offers new insights into the mechanisms of LiPS conversion."}],"date_updated":"2026-07-23T11:42:17Z","OA_place":"publisher","date_published":"2026-01-15T00:00:00Z","OA_type":"hybrid","has_accepted_license":"1","ddc":["540"],"tmp":{"image":"/images/cc_by_nc_nd.png","short":"CC BY-NC-ND (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"},"keyword":["amorphous","high entropy alloy","in situ electrochemical impedance spec-troscopy","in situ Raman","Li–S batteries"],"article_type":"original","fulldoi":"https://doi.org/10.1002/adfm.202513859","isi":1,"das_tickbox":"1","day":"15","publisher":"Wiley","citation":{"mla":"He, Ren, et al. “Amorphous High Entropy Alloy Nanosheets Enabling Robust Li–S Batteries.” Advanced Functional Materials, vol. 36, no. 5, e13859, Wiley, 2026, doi:10.1002/adfm.202513859.","short":"R.

We consider the prototypical problem of estimating two statistically independent signals in a mixed generalized linear model with Gaussian covariates. Spectral methods are a popular class of estimators which output the top two eigenvectors of a suitable data-dependent matrix. However, despite the wide applicability, their design is still obtained via heuristic considerations, and the number of samples 𝑛 needed to guarantee recovery is superlinear in the signal dimension 𝑑. In this paper, we develop exact asymptotics on spectral methods in the challenging proportional regime in which 𝑛,𝑑 grow large and their ratio converges to a finite constant. This allows us optimize the design of the spectral method, and combine it with a simple linear estimator, to minimize the estimation error. Our characterization exploits a mix of tools from random matrices, free probability, and the theory of approximate message passing algorithms. Numerical simulations for mixed linear regression and phase retrieval demonstrate the advantage enabled by our analysis over existing designs of spectral methods.","lang":"eng"}],"date_updated":"2026-08-12T06:23:07Z","OA_place":"publisher","date_published":"2026-06-01T00:00:00Z","PlanS_conform":"1","has_accepted_license":"1","OA_type":"hybrid","ddc":["000"],"keyword":["spectral estimator","generalized linear models","mixed regression","high-dimensional asymptotics","random matrix theory","approximate message passing (AMP)"],"tmp":{"image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"article_type":"original","fulldoi":"https://doi.org/10.1137/24m1702854","arxiv":1,"das_tickbox":"0","day":"01","publisher":"SIAM","year":"2026","citation":{"chicago":"Zhang, Yihan, Marco Mondelli, and Ramji Venkataramanan. “Precise Asymptotics for Spectral Methods in Mixed Generalized Linear Models.” SIAM Journal on Mathematics of Data Science.

A central puzzle has been the clear benefit of scaling architecture size and overfitting the training set in supervised learning tasks. This evidence, in apparent contradiction with classical statistical learning theory, pushed researchers to develop a new theory capturing the interplay between the algorithmic and architectural bias of training and the specific target function, differently from previous methods rooted in uniform stability.\r\nThis approach has enabled a grounded understanding of novel learning regimes, typically through formal limits where the number of training samples $n$, data dimensions $d$, and model parameters $p$ grow to infinity at different rates. \\\\\r\nIn this thesis, we follow this approach, focusing on the trustworthiness of high-dimensional models: properties that are difficult to control during training or deployment and often emerge under unpredictable or adversarial conditions. In such settings, it is crucial to formally ensure a priori the reliability of machine learning systems.\r\nFirst, we study data memorization, both as label fitting and as the storage of private information about training samples in trained parameters. We prove that $p = \\Omega(n)$ parameters are sufficient for a deep neural network to memorize a generic set of labels, and for a model to memorize spurious features across training data. We then give evidence that $p = \\Omega(dn)$ parameters are instead necessary for an adversary to reconstruct the full training set from the trained parameters.\r\nSecond, we study robustness, both to adversarial perturbations and to distribution shift. We first prove that $p = \\Omega(dn)$ parameters can be sufficient for a class of neural networks to overfit the training data while guaranteeing robustness to adversarial perturbations. Then, we focus on spurious correlations learning in high-dimensional regression, studying the effect of the ridge regularization parameter in the proportional regime $n = \\Theta(d)$, and connecting it via an equivalence argument to the role of over-parameterization $p = \\Omega(n)$ in neural networks. We also investigate the architectural bias of attention-based networks, showing that they are sensitive to the replacement of individual words in an embedded sentence, allowing them to generalize on sentences where the contextual meaning depends on one or few words.\r\nFinally, we study differentially private optimization in high-dimensional regimes. We prove that standard private gradient methods do not suffer in the over-parameterized regime $p = \\Omega(n)$, challenging the current wisdom based on stability-derived generalization bounds. We then consider linear regression in the proportional regime $n = \\Theta(d)$, showing that standard private gradient descent can achieve optimal rates under appropriate hyper-parameter scaling, such as sufficiently small gradient clipping constants, whose role is still debated in practice.","lang":"eng"}],"date_published":"2026-09-08T00:00:00Z","has_accepted_license":"1","ddc":["519"],"keyword":["machine learning","high-dimensional statistics","deep learning theory","privacy","memorization","robustness"],"fulldoi":"https://doi.org/10.15479/AT-ISTA-22857","OA_place":"publisher"},{"month":"10","department":[{"_id":"MaKw"}],"language":[{"iso":"eng"}],"publication_status":"epub_ahead","project":[{"grant_number":"E624","name":"THRESHOLDS IN SEMI-RANDOM PROCESSES AND GRAPH EMBEDDINGS","_id":"e19fef4c-1f3d-11f0-ac04-b8b1af6886d8"}],"quality_controlled":"1","supplementarymaterial":"no","date_created":"2026-10-18T22:01:53Z","article_processing_charge":"No","publication":"Discrete and Computational Geometry","mathsc":["05C05","05C35","11K38"],"author":[{"full_name":"Hollom, Lawrence","last_name":"Hollom","first_name":"Lawrence"},{"first_name":"Lyuben","full_name":"Lichev, Lyuben","last_name":"Lichev","id":"9aa8388e-d003-11ee-8458-c4c1d7447977"},{"full_name":"Mond, Adva","last_name":"Mond","first_name":"Adva"},{"first_name":"Julien","full_name":"Portier, Julien","last_name":"Portier"}],"scopus_import":"1","publication_identifier":{"eissn":["1432-0444"],"issn":["0179-5376"]},"title":"A note on high-dimensional discrepancy of subtrees","oa":1,"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2412.04170","open_access":"1"}],"doi":"10.1007/s00454-025-00790-x","type":"journal_article","arxiv":1,"das_tickbox":"1","day":"09","year":"2026","acknowledgement":"The authors would like to thank both Béla Bollobás and the anonymous reviewer for their careful readings of the manuscript and for their valuable comments.

We also settle a related conjecture on oriented discrepancy of subtrees by the same authors.","lang":"eng"}],"date_updated":"2026-10-19T08:20:42Z","OA_place":"repository","date_published":"2026-10-09T00:00:00Z","OA_type":"green","fulldoi":"https://doi.org/10.1007/s00454-025-00790-x","article_type":"original","keyword":["Trees","High-dimensional discrepancy","Oriented discrepancy"]},{"date_created":"2026-03-30T12:22:47Z","article_processing_charge":"No","quality_controlled":"1","volume":19,"language":[{"iso":"eng"}],"publication_status":"published","page":"31363-31370","month":"08","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2503.20946"}],"doi":"10.1021/acsnano.5c05186","type":"journal_article","publication_identifier":{"issn":["1936-0851"],"eissn":["1936-086X"]},"title":"Nanophotonic thermal management in X-ray tubes","oa":1,"extern":"1","scopus_import":"1","author":[{"last_name":"Pajovic","full_name":"Pajovic, Simo","first_name":"Simo"},{"first_name":"Charles","full_name":"Roques-Carmes, Charles","last_name":"Roques-Carmes","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82"},{"last_name":"Choi","full_name":"Choi, Seou","first_name":"Seou"},{"full_name":"Kooi, Steven E.","last_name":"Kooi","first_name":"Steven E."},{"first_name":"Rajiv","full_name":"Gupta, Rajiv","last_name":"Gupta"},{"first_name":"Michael E.","full_name":"Zalis, Michael E.","last_name":"Zalis"},{"first_name":"Ivan","full_name":"Čelanović, Ivan","last_name":"Čelanović"},{"full_name":"Soljačić, Marin","last_name":"Soljačić","first_name":"Marin"}],"publication":"ACS Nano","intvolume":" 19","external_id":{"arxiv":["2503.20946"]},"issue":"35","oa_version":"Preprint","_id":"21524","status":"public","citation":{"mla":"Pajovic, Simo, et al. “Nanophotonic Thermal Management in X-Ray Tubes.” ACS Nano, vol. 19, no. 35, American Chemical Society, 2025, pp. 31363–70, doi:10.1021/acsnano.5c05186.","short":"S.

Therefore, thermal management is a critical barrier to the development of more powerful X-ray tubes with higher brightness and spatial coherence, which are needed to translate imaging modalities such as phase-contrast imaging to the clinic. In rotating anode X-ray tubes, the most common design, thermal radiation is a bottleneck that prevents efficient cooling of the anode─the hottest part of the device by far. We predict that nanophotonic patterning of the anode of an X-ray tube enhances heat dissipation via thermal radiation, enabling it to operate at higher powers without an increase in temperature. The focal spot size, which is related to the spatial coherence of generated X-rays, can also be reduced at a constant temperature. A major advantage of our “nanophotonic thermal management” approach is that in principle, it allows complete control over the spectrum and direction of thermal radiation, which can lead to optimal thermal routing and improved performance.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"quality_controlled":"1","date_created":"2026-07-27T12:30:24Z","article_processing_charge":"No","month":"04","volume":19,"language":[{"iso":"eng"}],"publication_status":"published","article_number":"044057","extern":"1","publication_identifier":{"eissn":["1748-9326"]},"oa":1,"title":"Hydrological regimes and evaporative flux partitioning at the climatic ends of high mountain Asia","doi":"10.1088/1748-9326/ad25a0","main_file_link":[{"url":"https://doi.org/10.1088/1748-9326/ad25a0","open_access":"1"}],"type":"journal_article","publication":"Environmental Research Letters","author":[{"last_name":"Fugger","full_name":"Fugger, S","first_name":"S"},{"last_name":"Shaw","full_name":"Shaw, T E","first_name":"T E"},{"last_name":"Jouberton","full_name":"Jouberton, A","first_name":"A"},{"last_name":"Miles","full_name":"Miles, E S","first_name":"E S"},{"first_name":"P","full_name":"Buri, P","last_name":"Buri"},{"last_name":"McCarthy","full_name":"McCarthy, M","first_name":"M"},{"first_name":"C","full_name":"Fyffe, C","last_name":"Fyffe"},{"full_name":"Fatichi, Simone","id":"cf8e546b-a9b0-11f0-a43b-aa89ed1b56d6","last_name":"Fatichi","first_name":"Simone"},{"first_name":"M","last_name":"Kneib","full_name":"Kneib, M"},{"first_name":"Peter","full_name":"Molnar, Peter","last_name":"Molnar"},{"last_name":"Pellicciotti","full_name":"Pellicciotti, F","first_name":"F"}],"scopus_import":"1","issue":"4","intvolume":" 19","day":"09","das_tickbox":"1","citation":{"chicago":"Fugger, S, T E Shaw, A Jouberton, E S Miles, P Buri, M McCarthy, C Fyffe, et al. “Hydrological Regimes and Evaporative Flux Partitioning at the Climatic Ends of High Mountain Asia.” Environmental Research Letters.

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, 24 K, 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 24 K, 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"}],"date_updated":"2026-08-07T11:03:46Z"},{"date_updated":"2025-04-14T07:43:56Z","file_date_updated":"2023-07-31T09:02:27Z","abstract":[{"lang":"eng","text":"Recent experimental advances have inspired the development of theoretical tools to describe the non-equilibrium dynamics of quantum systems.

It provides structural scaffolding for the cells embedded within it and is essential in regulating numerous physiological processes, including cell migration and proliferation, wound healing, and stem cell fate. \r\nDespite extensive study, detailed structural knowledge of ECM components in physiologically relevant conditions is still rudimentary. This is due to methodological limitations in specimen preparation protocols which are incompatible with keeping large samples, such as the ECM, in their native state for subsequent imaging. Conventional electron microscopy (EM) techniques rely on fixation, dehydration, contrasting, and sectioning. This results in the alteration of a highly hydrated environment and the potential introduction of artifacts. Other structural biology techniques, such as nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography, allow high-resolution analysis of protein structures but only work on homogenous and purified samples, hence lacking contextual information. Currently, no approach exists for the ultrastructural and structural study of extracellular components under native conditions in a physiological, 3D environment. \r\nIn this thesis, I have developed a workflow that allows for the ultrastructural analysis of the ECM in near-native conditions at molecular resolution. The developments I introduced include implementing a novel specimen preparation workflow for cell-derived matrices (CDMs) to render them compatible with ion-beam milling and subsequent high-resolution cryo-electron tomography (ET). \r\nTo this end, I have established protocols to generate CDMs grown over several weeks on EM grids that are compatible with downstream cryo-EM sample preparation and imaging techniques. Characterization of these ECMs confirmed that they contain essential ECM components such as collagen I, collagen VI, and fibronectin I in high abundance and hence represent a bona fide biologically-relevant sample. I successfully optimized vitrification of these specimens by testing various vitrification techniques and cryoprotectants. \r\nIn order to obtain high-resolution molecular insights into the ultrastructure and organization of CDMs, I established cryo-focused ion beam scanning electron microscopy (FIBSEM) on these challenging and complex specimens. I explored different approaches for the creation of thin cryo-lamellae by FIB milling and succeeded in optimizing the cryo-lift-out technique, resulting in high-quality lamellae of approximately 200 nm thickness. \r\nHigh-resolution Cryo-ET of these lamellae revealed for the first time the architecture of native CDM in the context of matrix-secreting cells. This allowed for the in situ visualization of fibrillar matrix proteins such as collagen, laying the foundation for future structural and ultrastructural characterization of these proteins in their near-native environment. \r\nIn summary, in this thesis, I present a novel workflow that combines state-of-the-art cryo-EM specimen preparation and imaging technologies to permit characterization of the ECM, an important tissue component in higher organisms. This innovative and highly versatile workflow will enable addressing far-reaching questions on ECM architecture, composition, and reciprocal ECM-cell interactions.","lang":"eng"}],"file_date_updated":"2024-02-08T23:30:04Z","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","fulldoi":"https://doi.org/10.15479/at:ista:12491","keyword":["cryo-EM","cryo-ET","FIB milling","method development","FIBSEM","extracellular matrix","ECM","cell-derived matrices","CDMs","cell culture","high pressure freezing","HPF","structural biology","tomography","collagen"],"ddc":["570"],"has_accepted_license":"1","date_published":"2023-02-02T00:00:00Z","OA_place":"publisher","oa_version":"Published Version","status":"public","_id":"12491","citation":{"ama":"Zens B.

In this work, we aim to explore the existence of Lyα haloes around individual UV-selected galaxies, rather than around Lyα emitters (LAEs), at high redshifts. Our sample was continuum-selected with F775W ≤ 27.5, and spectroscopic redshifts were assigned or constrained for all the sources thanks to the deepest (100- to 140-h) existing Very Large Telescope (VLT)/Multi-Unit Spectroscopic Explorer (MUSE) data with adaptive optics. The final sample includes 21 galaxies that are purely F775W-magnitude selected within the redshift range z ≈ 2.9 − 4.4 and within a UV magnitude range −20 ≤ M1500 ≤ −18, thus avoiding any bias toward LAEs. We tested whether galaxy’s Lyα emission is significantly more extended than the MUSE PSF-convolved continuum component. We find 17 LAHs and four non-LAHs. We report the first individual detections of extended Lyα emission around non-LAEs. The Lyα halo fraction is thus as high as 81.0−11.2+10.3%, which is close to that for LAEs at z = 3 − 6 in the literature. This implies that UV-selected galaxies generally have a large amount of hydrogen in their CGM. We derived the mean surface brightness (SB) profile for our LAHs with cosmic dimming corrections and find that Lyα emission extends to 5.4 arcsec (≃40 physical kpc at the midpoint redshift z = 3.6) above the typical 1σ SB limit. The incidence rate of surrounding gas detected in Lyα per one-dimensional line of sight per unit redshift, dn/dz, is estimated to be 0.76−0.09+0.09 for galaxies with M1500 ≤ −18 mag at z ≃ 3.7. Assuming that Lyα emission and absorption arise in the same gas, this suggests, based on abundance matching, that LAHs trace the same gas as damped Lyα systems (DLAs) and sub-DLAs."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: high-redshift / galaxies: formation / galaxies: evolution / cosmology: observations"],"fulldoi":"https://doi.org/10.1051/0004-6361/202142302","article_type":"original","date_published":"2022-04-07T00:00:00Z","oa_version":"Published Version","status":"public","_id":"11488","publisher":"EDP Sciences","year":"2022","acknowledgement":"We thank the anonymous referee for constructive comments and suggestions.

We present a case study of ID53 at z = 4.77, the UV-brightest (but L⋆) star-forming galaxy at z > 3 in the MUSE eXtremely Deep Field with a mass of ≈109 M⊙. In addition to very strong Lyman-α (Lyα) emission, we clearly detect the (stellar) continuum and an N V P Cygni feature, interstellar absorption, fine-structure emission and nebular C IV emission lines in the 140 h spectrum. Continuum emission from two spatially resolved components in Hubble Space Telescope data are blended in the MUSE data, but we show that the nebular C IV emission originates from a subcomponent of the galaxy. The UV spectrum can be fit with recent BPASS stellar population models combined with single-burst or continuous star formation histories (SFHs), a standard initial mass function, and an attenuation law. Models with a young age and low metallicity (log10(age/yr) = 6.5–7.6 and [Z/H] = −2.15 to −1.15) are preferred, but the details depend on the assumed SFH. The intrinsic Hα luminosity of the best-fit models is an order of magnitude higher than the Hα luminosity inferred from Spitzer/IRAC data, which either suggests a high escape fraction of ionising photons, a high relative attenuation of nebular to stellar dust, or a complex SFH. The metallicity appears lower than the metallicity in more massive galaxies at z = 3 − 5, consistent with the scenario according to which younger galaxies have lower metallicities. This chemical immaturity likely facilitates Lyα escape, explaining why the Lyα equivalent width is anti-correlated with stellar metallicity. Finally, we stress that uncertainties in SFHs impose a challenge for future inferences of the stellar metallicity of young galaxies. This highlights the need for joint (spatially resolved) analyses of stellar spectra and photo-ionisation models."}],"date_published":"2022-03-30T00:00:00Z","keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: high-redshift / techniques: spectroscopic / galaxies: stellar content / galaxies: formation"],"fulldoi":"https://doi.org/10.1051/0004-6361/202142187","article_type":"original","publication_status":"published","volume":660,"language":[{"iso":"eng"}],"month":"03","article_processing_charge":"No","date_created":"2022-07-05T15:25:35Z","quality_controlled":"1","scopus_import":"1","publication":"Astronomy & Astrophysics","author":[{"full_name":"Matthee, Jorryt J","id":"7439a258-f3c0-11ec-9501-9df22fe06720","last_name":"Matthee","orcid":"0000-0003-2871-127X","first_name":"Jorryt J"},{"first_name":"Anna","last_name":"Feltre","full_name":"Feltre, Anna"},{"first_name":"Michael","last_name":"Maseda","full_name":"Maseda, Michael"},{"last_name":"Nanayakkara","full_name":"Nanayakkara, Themiya","first_name":"Themiya"},{"full_name":"Boogaard, Leindert","last_name":"Boogaard","first_name":"Leindert"},{"first_name":"Roland","last_name":"Bacon","full_name":"Bacon, Roland"},{"full_name":"Verhamme, Anne","last_name":"Verhamme","first_name":"Anne"},{"full_name":"Leclercq, Floriane","last_name":"Leclercq","first_name":"Floriane"},{"first_name":"Haruka","full_name":"Kusakabe, Haruka","last_name":"Kusakabe"},{"first_name":"Tanya","last_name":"Urrutia","full_name":"Urrutia, Tanya"},{"first_name":"Lutz","full_name":"Wisotzki, Lutz","last_name":"Wisotzki"}],"title":"Deciphering stellar metallicities in the early universe: Case study of a young galaxy at z = 4.77 in the MUSE eXtremely Deep Field","oa":1,"publication_identifier":{"issn":["0004-6361"],"eissn":["1432-0746"]},"type":"journal_article","main_file_link":[{"url":"https://arxiv.org/abs/2111.14855","open_access":"1"}],"doi":"10.1051/0004-6361/202142187","article_number":"A10","extern":"1"},{"_id":"11497","status":"public","oa_version":"Published Version","arxiv":1,"day":"25","citation":{"apa":"Kerutt, J., Wisotzki, L., Verhamme, A., Schmidt, K.

The hydrogen Lyman α line is often the only measurable feature in optical spectra of high-redshift galaxies. Its shape and strength are influenced by radiative transfer processes and the properties of the underlying stellar population. High equivalent widths of several hundred Å are especially hard to explain by models and could point towards unusual stellar populations, for example with low metallicities, young stellar ages, and a top-heavy initial mass function. Other aspects influencing equivalent widths are the morphology of the galaxy and its gas properties.\r\nAims. The aim of this study is to better understand the connection between the Lyman α rest-frame equivalent width (EW0) and spectral properties as well as ultraviolet (UV) continuum morphology by obtaining reliable EW0 histograms for a statistical sample of galaxies and by assessing the fraction of objects with large equivalent widths.\r\nMethods. We used integral field spectroscopy from the Multi Unit Spectroscopic Explorer (MUSE) combined with broad-band data from the Hubble Space Telescope (HST) to measure EW0. We analysed the emission lines of 1920 Lyman α emitters (LAEs) detected in the full MUSE-Wide (one hour exposure time) and MUSE-Deep (ten hour exposure time) surveys and found UV continuum counterparts in archival HST data. We fitted the UV continuum photometric images using the Galfit software to gain morphological information on the rest-UV emission and fitted the spectra obtained from MUSE to determine the double peak fraction, asymmetry, full-width at half maximum, and flux of the Lyman α line.\r\nResults. The two surveys show different histograms of Lyman α EW0. In MUSE-Wide, 20% of objects have EW0 > 240 Å, while this fraction is only 11% in MUSE-Deep and ≈16% for the full sample. This includes objects without HST continuum counterparts (one-third of our sample), for which we give lower limits for EW0. The object with the highest securely measured EW0 has EW0 = 589 ± 193 Å (the highest lower limit being EW0 = 4464 Å). We investigate the connection between EW0 and Lyman α spectral or UV continuum morphological properties.\r\nConclusions. The survey depth has to be taken into account when studying EW0 distributions.

Here, we introduce an emissivity framework based on Lyα emitters (LAEs), which naturally hones in on the subset of galaxies responsible for the ionizing background due to the intimate connection between production and escape of Lyα and LyC photons. Using constraints on the escape fractions of bright LAEs (LLyα > 0.2L*) at z ≈ 2 obtained from resolved Lyα profiles, and arguing for their redshift-invariance, we show that: (i) quasars and LAEs together reproduce the relatively flat emissivity at z ≈ 2–6, which is non-trivial given the strong evolution in both the star formation density and quasar number density at these epochs and (ii) LAEs produce late and rapid reionization between z ≈ 6−9 under plausible assumptions. Within this framework, the >10 × rise in the UV population-averaged fesc between z ≈ 3–7 naturally arises due to the same phenomena that drive the growing LAE fraction with redshift. Generally, a LAE dominated emissivity yields a peak in the distribution of the ionizing budget with UV luminosity as reported in latest simulations. Using our adopted parameters (fesc=50 per cent, ξion = 1025.9 Hz erg−1 for half the bright LAEs), a highly ionizing minority of galaxies with MUV < −17 accounts for the entire ionizing budget from star-forming galaxies. Rapid flashes of LyC from such rare galaxies produce a ‘disco’ ionizing background. We conclude proposing tests to further develop our suggested Lyα-anchored formalism."}],"date_updated":"2024-10-14T11:32:26Z","issue":"4","external_id":{"arxiv":["2110.11967"]},"intvolume":" 512","arxiv":1,"day":"01","publisher":"Oxford University Press","year":"2022","acknowledgement":"We thank an anonymous referee for an encouraging and constructive report that helped improving the quality of this work.

Plants are\r\nsessile organisms, thus to compensate for their lack of mobility, they evolved a variety of\r\nmechanisms enabling them to flexibly adjust their physiological, growth and developmental\r\nprocesses to fluctuating temperatures and to survive in harsh environments. While these unique\r\nadaptation abilities provide an important evolutionary advantage, overall modulation of plant\r\ngrowth and developmental program due to non-optimal temperature negatively affects biomass\r\nproduction, crop productivity or sensitivity to pathogens. Thus, understanding molecular\r\nprocesses underlying plant adaptation to increased temperature can provide important\r\nresources for breeding strategies to ensure sufficient agricultural food production.\r\nAn increase in ambient temperature by a few degrees leads to profound changes in organ growth\r\nincluding enhanced hypocotyl elongation, expansion of petioles, hyponastic growth of leaves and\r\ncotyledons, collectively named thermomorphogenesis (Casal & Balasubramanian, 2019). Auxin,\r\none of the best-studied growth hormones, plays an essential role in this process by direct\r\nactivation of transcriptional and non-transcriptional processes resulting in elongation growth\r\n(Majda & Robert, 2018).To modulate hypocotyl growth in response to high ambient temperature\r\n(hAT), auxin needs to be redistributed accordingly. PINs, auxin efflux transporters, are key\r\ncomponents of the polar auxin transport (PAT) machinery, which controls the amount and\r\ndirection of auxin translocated in the plant tissues and organs(Adamowski & Friml, 2015). Hence,\r\nPIN-mediated transport is tightly linked with thermo-morphogenesis, and interference with PAT\r\nthrough either chemical or genetic means dramatically affecting the adaptive responses to hAT.\r\nIntriguingly, despite the key role of PIN mediated transport in growth response to hAT, whether\r\nand how PINs at the level of expression adapt to fluctuation in temperature is scarcely\r\nunderstood.\r\nWith genetic, molecular and advanced bio-imaging approaches, we demonstrate the role of PIN\r\nauxin transporters in the regulation of hypocotyl growth in response to hAT. We show that via\r\nadjustment of PIN3, PIN4 and PIN7 expression in cotyledons and hypocotyls, auxin distribution is modulated thereby determining elongation pattern of epidermal cells at hAT. Furthermore, we\r\nidentified three Zinc-Finger (ZF) transcription factors as novel molecular components of the\r\nthermo-regulatory network, which through negative regulation of PIN transcription adjust the\r\ntransport of auxin at hAT. Our results suggest that the ZF-PIN module might be a part of the\r\nnegative feedback loop attenuating the activity of the thermo-sensing pathway to restrain\r\nexaggerated growth and developmental responses to hAT."}],"file_date_updated":"2023-09-09T22:30:03Z","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","date_updated":"2026-04-07T14:30:39Z","alternative_title":["ISTA Thesis"],"OA_place":"publisher","fulldoi":"https://doi.org/10.15479/at:ista:11879","keyword":["high ambient temperature","auxin","PINs","Zinc-Finger proteins","thermomorphogenesis","stress"],"ddc":["580"],"date_published":"2022-08-17T00:00:00Z","has_accepted_license":"1","year":"2022","citation":{"ieee":"C.

The strongest main UV emission line, Lyα, has been instrumental in advancing the general knowledge of galaxy formation in the early universe. However, observing Lyα emission becomes increasingly challenging at z ≳ 6 when the neutral hydrogen fraction of the circumgalactic and intergalactic media increases. Secondary weaker UV emission lines provide important alternative methods for studying galaxy properties at high redshift. We present a large sample of rest-frame UV emission line sources at intermediate redshift for calibrating and exploring the connection between secondary UV lines and the emitting galaxies’ physical properties and their Lyα emission. The sample of 2052 emission line sources with 1.5 < z < 6.4 was collected from integral field data from the MUSE-Wide and MUSE-Deep surveys taken as part of Guaranteed Time Observations. The objects were selected through untargeted source detection (i.e., no preselection of sources as in dedicated spectroscopic campaigns) in the three-dimensional MUSE data cubes. We searched optimally extracted one-dimensional spectra of the full sample for UV emission features via emission line template matching, resulting in a sample of more than 100 rest-frame UV emission line detections. We show that the detection efficiency of (non-Lyα) UV emission lines increases with survey depth, and that the emission line strength of He IIλ1640 Å, [O III] λ1661 + O III] λ1666, and [Si III] λ1883 + Si III] λ1892 correlate with the strength of [C III] λ1907 + C III] λ1909. The rest-frame equivalent width (EW0) of [C III] λ1907 + C III] λ1909 is found to be roughly 0.22 ± 0.18 of EW0(Lyα). We measured the velocity offsets of resonant emission lines with respect to systemic tracers. For C IVλ1548 + C IVλ1551 we find that ΔvC IV ≲ 250 km s−1, whereas ΔvLyα falls in the range of 250−500 km s−1 which is in agreement with previous results from the literature. The electron density ne measured from [Si III] λ1883 + Si III] λ1892 and [C III] λ1907 + C III] λ1909 line flux ratios is generally < 105 cm−3 and the gas-phase abundance is below solar at 12 + log10(O/H)≈8. Lastly, we used “PhotoIonization Model Probability Density Functions” to infer physical parameters of the full sample and individual systems based on photoionization model parameter grids and observational constraints from our UV emission line searches. This reveals that the UV line emitters generally have ionization parameter log10(U) ≈ −2.5 and metal mass fractions that scatter around Z ≈ 10−2, that is Z ≈ 0.66 Z⊙. Value-added catalogs of the full sample of MUSE objects studied in this work and a collection of UV line emitters from the literature are provided with this paper."}],"article_processing_charge":"No","date_created":"2022-07-06T08:49:03Z","quality_controlled":"1","publication_status":"published","volume":654,"language":[{"iso":"eng"}],"month":"10","oa":1,"title":"Recovery and analysis of rest-frame UV emission lines in 2052 galaxies observed with MUSE at 1.5 < z < 6.4","publication_identifier":{"eissn":["1432-0746"],"issn":["0004-6361"]},"type":"journal_article","doi":"10.1051/0004-6361/202140876","main_file_link":[{"url":"https://arxiv.org/abs/2108.01713","open_access":"1"}],"article_number":"A80","extern":"1","scopus_import":"1","publication":"Astronomy & Astrophysics","author":[{"full_name":"Schmidt, K.

These structures have been observed in overdensities of Lyα emitters in the MUSE Extremely Deep Field, a 140 h deep MUSE observation located in the Hubble Ultra-Deep Field. Among the 22 overdense regions identified, five are likely to harbor very extended Lyα emission at high significance with an average surface brightness of 5 × 10−20 erg s−1 cm−2 arcsec−2. Remarkably, 70% of the total Lyα luminosity from these filaments comes from beyond the circumgalactic medium of any identified Lyα emitter. Fluorescent Lyα emission powered by the cosmic UV background can only account for less than 34% of this emission at z ≈ 3 and for not more than 10% at higher redshift. We find that the bulk of this diffuse emission can be reproduced by the unresolved Lyα emission of a large population of ultra low-luminosity Lyα emitters (< 1040 erg s−1), provided that the faint end of the Lyα luminosity function is steep (α ⪅ −1.8), it extends down to luminosities lower than 1038 − 1037 erg s−1, and the clustering of these Lyα emitters is significant (filling factor < 1/6). If these Lyα emitters are powered by star formation, then this implies their luminosity function needs to extend down to star formation rates < 10−4 M⊙ yr−1. These observations provide the first detection of the cosmic web in Lyα emission in typical filamentary environments and the first observational clue indicating the existence of a large population of ultra low-luminosity Lyα emitters at high redshift."}],"external_id":{"arxiv":["2102.05516"]},"intvolume":" 647","_id":"11500","status":"public","oa_version":"Published Version","arxiv":1,"day":"18","publisher":"EDP Sciences","year":"2021","citation":{"mla":"Bacon, R., et al. “The MUSE Extremely Deep Field: The Cosmic Web in Emission at High Redshift.” Astronomy & Astrophysics, vol. 647, A107, EDP Sciences, 2021, doi:10.1051/0004-6361/202039887.","short":"R.

We find a correlation between Ly α luminosity (LLy α) and rest-frame UV (MUV), with best fit MUV=−1.6+0.2−0.3log10(LLyα/ergs−1)+47+12−11 and a shallower relation between LLy α and stellar mass (M⋆), with best fit log10(M⋆/M⊙)=0.9+0.1−0.1log10(LLyα/ergs−1)−28+4.0−3.8. An increasing LLy α cut predominantly lowers the number density of faint MUV and low M⋆ LAEs. We estimate a proxy for the full UV LFs and SMFs of LAEs with simple assumptions of the faint end slope. For the UV LF, we find a brightening of the characteristic UV luminosity (M∗UV) with increasing redshift and a decrease of the characteristic number density (Φ*). For the SMF, we measure a characteristic stellar mass (M∗⋆/M⊙) increase with increasing redshift, and a Φ* decline. However, if we apply a uniform luminosity cut of log10(LLyα/ergs−1)≥43.0, we find much milder to no evolution in the UV and SMF of LAEs. The UV luminosity density (ρUV) of the full sample of LAEs shows moderate evolution and the stellar mass density (ρM) decreases, with both being always lower than the total ρUV and ρM of more typical galaxies but slowly approaching them with increasing redshift. Overall, our results indicate that both ρUV and ρM of LAEs slowly approach the measurements of continuum-selected galaxies at z > 6, which suggests a key role of LAEs in the epoch of reionization.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_type":"original","fulldoi":"https://doi.org/10.1093/mnras/stab1218","keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: evolution","galaxies: high-redshift","galaxies: luminosity function","mass function"],"date_published":"2021-07-01T00:00:00Z","oa_version":"Preprint","status":"public","_id":"11524","year":"2021","citation":{"mla":"Santos, S., et al. “The Evolution of the UV Luminosity and Stellar Mass Functions of Lyman-α Emitters from z ∼ 2 to z ∼ 6.” Monthly Notices of the Royal Astronomical Society, vol. 505, no. 1, Oxford University Press, 2021, pp. 1117–34, doi:10.1093/mnras/stab1218.","short":"S.

For simplicity we focus on massive Dirac fermions with nonzero chemical potential, and work in 1 + 1 space-time dimensions. Using the entanglement entropy on an interval, we construct an entropic c-function that is finite. Unlike what happens in Lorentz-invariant theories, this c-function exhibits a strong violation of monotonicity; it also encodes the creation of long-range entanglement from the Fermi surface. Motivated by previous works on lattice models, we next calculate numerically the Renyi entropies and find Friedel-type oscillations; these are understood in terms of a defect operator product expansion. Furthermore, we consider the mutual information as a measure of correlation functions between different regions. Using a long-distance expansion previously developed by Cardy, we argue that the mutual information detects Fermi surface correlations already at leading order in the expansion. We also analyze the relative entropy and its Renyi generalizations in order to distinguish states with different charge and/or mass. In particular, we show that states in different superselection sectors give rise to a super-extensive behavior in the relative entropy. Finally, we discuss possible extensions to interacting theories, and argue for the relevance of some of these measures for probing non-Fermi liquids."}],"file_date_updated":"2024-04-10T09:18:38Z"},{"external_id":{"isi":["000747220900010"],"pmid":["34460295"]},"intvolume":" 55","day":"30","isi":1,"year":"2021","acknowledgement":"The authors would like to thank Feyza Nur Arslan, Suyash Naik, Diana Pinheiro, Alexandra Schauer, and Shayan Shamipour for their comments on the draft.

Morphogenesis involves an interplay between several factors, ranging from the gene regulatory networks determining cell fate and differentiation to the mechanical processes underlying cell and tissue shape changes. Thus, the study of morphogenesis has historically been based on multidisciplinary approaches at the interface of biology with physics and mathematics. Recent technological advances have further improved our ability to study morphogenesis by bridging the gap between the genetic and biophysical factors through the development of new tools for visualizing, analyzing, and perturbing these factors and their biochemical intermediaries. Here, we review how a combination of genetic, microscopic, biophysical, and biochemical approaches has aided our attempts to understand morphogenesis and discuss potential approaches that may be beneficial to such an inquiry in the future.","lang":"eng"}],"ec_funded":1,"date_updated":"2026-06-18T08:39:48Z","project":[{"grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020"}],"quality_controlled":"1","date_created":"2021-12-05T23:01:41Z","article_processing_charge":"No","month":"08","page":"209-233","department":[{"_id":"CaHe"}],"volume":55,"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["0066-4197"],"eissn":["1545-2948"]},"pmid":1,"oa":1,"title":"Dissecting organismal morphogenesis by bridging genetics and biophysics","doi":"10.1146/annurev-genet-071819-103748","main_file_link":[{"url":"https://doi.org/10.1146/annurev-genet-071819-103748","open_access":"1"}],"type":"journal_article","publication":"Annual Review of Genetics","author":[{"first_name":"Nikhil","orcid":"0000-0002-6425-5788","id":"C4D70E82-1081-11EA-B3ED-9A4C3DDC885E","last_name":"Mishra","full_name":"Mishra, Nikhil"},{"id":"39427864-F248-11E8-B48F-1D18A9856A87","last_name":"Heisenberg","full_name":"Heisenberg, Carl-Philipp J","first_name":"Carl-Philipp J","orcid":"0000-0002-0912-4566"}],"corr_author":"1","scopus_import":"1"}]
