While the MBL phase is robust to weak local perturbations, the fate of an MBL system coupled to a thermalizing quantum system that represents a “heat bath” is an open question that is actively investigated theoretically and experimentally. In this work, we consider the stability of an Anderson insulator with a finite density of particles interacting with a single mobile impurity—a small quantum bath. We give perturbative arguments that support the stability of localization in the strong interaction regime. Large-scale tensor network simulations of dynamics are employed to corroborate the presence of the localized phase and give quantitative predictions in the thermodynamic limit. We develop a phenomenological description of the dynamics in the strong interaction regime, and we demonstrate that the impurity effectively turns the Anderson insulator into an MBL phase, giving rise to nontrivial entanglement dynamics well captured by our phenomenology.","lang":"eng"}],"article_number":"L220203","main_file_link":[{"url":" https://doi.org/10.48550/arXiv.2109.07332","open_access":"1"}],"oa":1,"publication_status":"published","volume":105},{"author":[{"first_name":"Stefan","full_name":"Sack, Stefan","last_name":"Sack","orcid":"0000-0001-5400-8508","id":"dd622248-f6e0-11ea-865d-ce382a1c81a5"},{"last_name":"Medina Ramos","full_name":"Medina Ramos, Raimel A","first_name":"Raimel A","orcid":"0000-0002-5383-2869","id":"CE680B90-D85A-11E9-B684-C920E6697425"},{"last_name":"Michailidis","first_name":"Alexios","full_name":"Michailidis, Alexios","id":"36EBAD38-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8443-1064"},{"last_name":"Kueng","first_name":"Richard","full_name":"Kueng, Richard"},{"id":"47809E7E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2399-5827","last_name":"Serbyn","first_name":"Maksym","full_name":"Serbyn, Maksym"}],"type":"journal_article","day":"29","title":"Avoiding barren plateaus using classical shadows","ec_funded":1,"citation":{"short":"S.

The quantum hardware is used to implement a variational wave function and measure observables, whereas the classical computer is used to store and update the variational parameters. The optimization landscape of expressive variational ansätze is however dominated by large regions in parameter space, known as barren plateaus, with vanishing gradients, which prevents efficient optimization. In this work we propose a general algorithm to avoid barren plateaus in the initialization and throughout the optimization. To this end we define a notion of weak barren plateaus (WBPs) based on the entropies of local reduced density matrices. The presence of WBPs can be efficiently quantified using recently introduced shadow tomography of the quantum state with a classical computer. We demonstrate that avoidance of WBPs suffices to ensure sizable gradients in the initialization. In addition, we demonstrate that decreasing the gradient step size, guided by the entropies allows WBPs to be avoided during the optimization process. This paves the way for efficient barren plateau-free optimization on near-term devices.

It arises in many physical contexts. We are mostly concerned\r\nwith models applicable in the context of an impurity atom in a Bose-Einstein condensate as\r\nwell as the problem of electrons moving in polar crystals.\r\nThe model has a simple structure in which the interaction of the particle with the field is given\r\nby a term linear in the field’s creation and annihilation operators. In this work, we investigate\r\nthe properties of this model by providing rigorous estimates on various energies relevant to the\r\nproblem. The estimates are obtained, for the most part, by suitable operator techniques which\r\nconstitute the principal mathematical substance of the thesis.\r\nThe first application of these techniques is to derive the polaron model rigorously from first\r\nprinciples, i.e., from a full microscopic quantum-mechanical many-body problem involving an\r\nimpurity in an otherwise homogeneous system. We accomplish this for the N + 1 Bose gas\r\nin the mean-field regime by showing that a suitable polaron-type Hamiltonian arises at weak\r\ninteractions as a low-energy effective theory for this problem.\r\nIn the second part, we investigate rigorously the ground state of the model at fixed momentum\r\nand for large values of the coupling constant. Qualitatively, the system is expected to display\r\na transition from the quasi-particle behavior at small momenta, where the dispersion relation\r\nis parabolic and the particle moves through the medium dragging along a cloud of phonons, to\r\nthe radiative behavior at larger momenta where the polaron decelerates and emits free phonons.\r\nAt the same time, in the strong coupling regime, the bosonic field is expected to behave purely\r\nclassically. Accordingly, the effective mass of the polaron at strong coupling is conjectured to\r\nbe asymptotically equal to the one obtained from the semiclassical counterpart of the problem,\r\nfirst studied by Landau and Pekar in the 1940s. For polaron models with regularized form\r\nfactors and phonon dispersion relations of superfluid type, i.e., bounded below by a linear\r\nfunction of the wavenumbers for all phonon momenta as in the interacting Bose gas, we prove\r\nthat for a large window of momenta below the radiation threshold, the energy-momentum\r\nrelation at strong coupling is indeed essentially a parabola with semi-latus rectum equal to the\r\nLandau–Pekar effective mass, as expected.\r\nFor the Fröhlich polaron describing electrons in polar crystals where the dispersion relation is\r\nof the optical type and the form factor is formally UV–singular due to the nature of the point\r\ncharge-dipole interaction, we are able to give the corresponding upper bound. In contrast to\r\nthe regular case, this requires the inclusion of the quantum fluctuations of the phonon field,\r\nwhich makes the problem considerably more difficult.\r\nThe results are supplemented by studies on the absolute ground-state energy at strong coupling,\r\na proof of the divergence of the effective mass with the coupling constant for a wide class of\r\npolaron models, as well as the discussion of the apparent UV singularity of the Fröhlich model\r\nand the application of the techniques used for its removal for the energy estimates.\r\n"}],"_id":"11473","date_published":"2022-07-01T00:00:00Z","file":[{"content_type":"application/pdf","relation":"main_file","file_id":"11486","date_created":"2022-07-05T08:12:56Z","success":1,"file_name":"thes1_no_isbn_2_1b.pdf","creator":"kmysliwy","file_size":1830973,"checksum":"7970714a20a6052f75fb27a6c3e9976e","date_updated":"2022-07-05T08:12:56Z","access_level":"open_access"},{"date_created":"2022-07-05T08:15:52Z","file_id":"11487","relation":"source_file","content_type":"application/zip","checksum":"647a2011fdf56277096c9350fefe1097","access_level":"closed","date_updated":"2022-07-05T08:17:12Z","creator":"kmysliwy","file_size":5831060,"file_name":"thes_source.zip"}],"article_processing_charge":"No","acknowledged_ssus":[{"_id":"SSU"}],"publication_identifier":{"issn":["2663-337X"]},"date_updated":"2023-09-07T13:43:52Z","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","year":"2022","oa_version":"Published Version","has_accepted_license":"1","status":"public","department":[{"_id":"GradSch"},{"_id":"RoSe"}],"degree_awarded":"PhD","publisher":"Institute of Science and Technology Austria","supervisor":[{"id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6781-0521","last_name":"Seiringer","first_name":"Robert","full_name":"Seiringer, Robert"}],"date_created":"2022-06-30T12:15:03Z","month":"07","page":"138","doi":"10.15479/at:ista:11473","ddc":["515","539"],"language":[{"iso":"eng"}],"project":[{"name":"International IST Doctoral Program","grant_number":"665385","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"related_material":{"record":[{"id":"10564","relation":"part_of_dissertation","status":"public"},{"id":"8705","relation":"part_of_dissertation","status":"public"}]},"author":[{"last_name":"Mysliwy","first_name":"Krzysztof","full_name":"Mysliwy, Krzysztof","id":"316457FC-F248-11E8-B48F-1D18A9856A87"}],"type":"dissertation","alternative_title":["ISTA Thesis"],"day":"01","title":"Polarons in Bose gases and polar crystals: Some rigorous energy estimates","citation":{"apa":"Mysliwy, K.

It is a challenging problem to construct a protocol with similar security guarantees that can efficiently scale to large groups. A major bottleneck are the frequent key rotations users need to perform to achieve post compromise forward security.\r\n\r\nIn current proposals – most notably in TreeKEM (which is part of the IETF’s Messaging Layer Security (MLS) protocol draft) – for users in a group of size n to rotate their keys, they must each craft a message of size log(n) to be broadcast to the group using an (untrusted) delivery server.\r\n\r\nIn larger groups, having users sequentially rotate their keys requires too much bandwidth (or takes too long), so variants allowing any T≤n users to simultaneously rotate their keys in just 2 communication rounds have been suggested (e.g. “Propose and Commit” by MLS). Unfortunately, 2-round concurrent updates are either damaging or expensive (or both); i.e. they either result in future operations being more costly (e.g. via “blanking” or “tainting”) or are costly themselves requiring Ω(T) communication for each user [Bienstock et al., TCC’20].\r\n\r\nIn this paper we propose CoCoA; a new scheme that allows for T concurrent updates that are neither damaging nor costly. That is, they add no cost to future operations yet they only require Ω(log2(n)) communication per user. To circumvent the [Bienstock et al.] lower bound, CoCoA increases the number of rounds needed to complete all updates from 2 up to (at most) log(n); though typically fewer rounds are needed.\r\n\r\nThe key insight of our protocol is the following: in the (non-concurrent version of) TreeKEM, a delivery server which gets T concurrent update requests will approve one and reject the remaining T−1. In contrast, our server attempts to apply all of them. If more than one user requests to rotate the same key during a round, the server arbitrarily picks a winner. Surprisingly, we prove that regardless of how the server chooses the winners, all previously compromised users will recover after at most log(n) such update rounds.\r\n\r\nTo keep the communication complexity low, CoCoA is a server-aided CGKA. That is, the delivery server no longer blindly forwards packets, but instead actively computes individualized packets tailored to each user. As the server is untrusted, this change requires us to develop new mechanisms ensuring robustness of the protocol."}],"_id":"11476","date_published":"2022-05-25T00:00:00Z","publication_status":"published","main_file_link":[{"open_access":"1","url":"https://eprint.iacr.org/2022/251"}],"oa":1,"volume":13276,"citation":{"apa":"Alwen, J., Auerbach, B., Cueto Noval, M., Klein, K., Pascual Perez, G., Pietrzak, K.

However, organoids usually lack microglia, brain-resident immune cells, which are present in the early embryonic brain and participate in neuronal circuit development. Here, we find IBA1+ microglia-like cells alongside retinal cups between week 3 and 4 in 2.5D culture with an unguided retinal organoid differentiation protocol. Microglia do not infiltrate the neuroectoderm and instead enrich within non-pigmented, 3D-cystic compartments that develop in parallel to the 3D-retinal organoids. When we guide the retinal organoid differentiation with low-dosed BMP4, we prevent cup development and enhance microglia and 3D-cysts formation. Mass spectrometry identifies these 3D-cysts to express mesenchymal and epithelial markers. We confirmed this microglia-preferred environment also within the unguided protocol, providing insight into microglial behavior and migration and offer a model to study how they enter and distribute within the human brain."}],"_id":"11478","date_published":"2022-07-15T00:00:00Z","publication_status":"published","oa":1,"file_date_updated":"2022-07-04T08:19:25Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"volume":25,"citation":{"ama":"Bartalska K, Hübschmann V, Korkut M, et al.

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.","lang":"eng"}],"article_number":"A44"},{"publication_identifier":{"issn":["1422-0067"]},"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","date_updated":"2023-08-09T10:13:57Z","external_id":{"pmid":["35683031"],"isi":["000808733300001"]},"has_accepted_license":"1","oa_version":"Published Version","year":"2022","article_type":"original","volume":23,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"file_date_updated":"2022-07-06T07:36:59Z","oa":1,"publication_status":"published","_id":"11489","abstract":[{"text":"Much of plant development depends on cell-to-cell redistribution of the plant hormone auxin, which is facilitated by the plasma membrane (PM) localized PIN FORMED (PIN) proteins. Auxin export activity, developmental roles, subcellular trafficking, and polarity of PINs have been well studied, but their structure remains elusive besides a rough outline that they contain two groups of 5 alpha-helices connected by a large hydrophilic loop (HL). Here, we focus on the PIN1 HL as we could produce it in sufficient quantities for biochemical investigations to provide insights into its secondary structure. Circular dichroism (CD) studies revealed its nature as an intrinsically disordered protein (IDP), manifested by the increase of structure content upon thermal melting. Consistent with IDPs serving as interaction platforms, PIN1 loops homodimerize. PIN1 HL cytoplasmic overexpression in Arabidopsis disrupts early endocytic trafficking of PIN1 and PIN2 and causes defects in the cotyledon vasculature formation. In summary, we demonstrate that PIN1 HL has an intrinsically disordered nature, which must be considered to gain further structural insights. Some secondary structures may form transiently during pairing with known and yet-to-be-discovered interactors.","lang":"eng"}],"date_published":"2022-06-06T00:00:00Z","file":[{"file_size":2324542,"creator":"cchlebak","file_name":"2022_IntJMolSci_Bilanovicova.pdf","checksum":"e997a57a928ec9d51fad8ce824a05935","access_level":"open_access","date_updated":"2022-07-06T07:36:59Z","relation":"main_file","file_id":"11492","content_type":"application/pdf","date_created":"2022-07-06T07:36:59Z","success":1}],"issue":"11","article_processing_charge":"Yes","ddc":["570"],"doi":"10.3390/ijms23116352","language":[{"iso":"eng"}],"acknowledgement":"We thank Charo del Genio from Coventry University and Richard Napier from the University of Warwick for helpful discussion concerning protein modeling and inspiration concerning CD spectroscopy, respectively.

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."}],"article_number":"A10","article_processing_charge":"No","arxiv":1,"doi":"10.1051/0004-6361/202142187","keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: high-redshift / techniques: spectroscopic / galaxies: stellar content / galaxies: formation"],"language":[{"iso":"eng"}],"acknowledgement":"We thank the referee for thoughtful and constructive comments that have improved the quality of this manuscript.

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. We find that in general, high EW0 objects can have a wide range of spectral and UV morphological properties, which might reflect that the underlying causes for high EW0 values are equally varied.","lang":"eng"}],"date_published":"2022-03-25T00:00:00Z","external_id":{"arxiv":["2202.06642"]},"scopus_import":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2022-07-19T09:47:16Z","publication_identifier":{"issn":["0004-6361"],"eissn":["1432-0746"]},"article_type":"original","oa_version":"Published Version","year":"2022","publisher":"EDP Sciences","publication":"Astronomy & Astrophysics","quality_controlled":"1","status":"public","intvolume":"       659","month":"03","extern":"1","date_created":"2022-07-06T08:17:27Z","acknowledgement":"We thank the referee for thoughtful and constructive comments that have improved the quality of this manuscript.

Nine out of the 13 candidates are EMPGs with an oxygen abundance (O/H) less than ∼10% solar value (O/H)⊙, and four sources are contaminants of moderately metal-rich galaxies or no emission-line objects. Notably, two out of the nine EMPGs have extremely low stellar masses and oxygen abundances of 5 × 10⁴x–7 × -10⁵ M⊙ and 2%–3% (O/H)⊙, respectively. With a sample of five EMPGs with (Fe/O) measurements, two (three) of which are taken from this study (the literature), we confirm that two EMPGs with the lowest (O/H) ratios of ∼2% (O/H)⊙ show high (Fe/O) ratios of ∼0.1, close to the solar abundance ratio. Comparing galaxy chemical enrichment models, we find that the two EMPGs cannot be explained by a scenario of metal-poor gas accretion/episodic star formation history due to their low (N/O) ratios. We conclude that the two EMPGs can be reproduced by the inclusion of bright hypernovae and/or hypothetical pair-instability supernovae (SNe) preferentially produced in a metal-poor environment. This conclusion implies that primordial galaxies at z ∼ 10 could have a high abundance of Fe that did not originate from Type Ia SNe with delays and that Fe may not serve as a cosmic clock for primordial galaxies."}],"_id":"11509","date_published":"2022-01-31T00:00:00Z","article_number":"111","issue":"2","article_processing_charge":"No","arxiv":1,"doi":"10.3847/1538-4357/ac3509","language":[{"iso":"eng"}],"keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"acknowledgement":"We thank the referee for the valuable comments.

A record of this evolution is preserved in galaxy stellar populations, which we can access using absorption-line spectroscopy. Here we explore the large LEGA-C survey (DR3) to investigate the role of the environment and stellar mass on stellar populations at z ∼ 0.6–1 in the COSMOS field. Leveraging the statistical power and depth of LEGA-C, we reveal significant gradients in Dn4000 and Hδ equivalent widths (EWs) distributions over the stellar mass versus environment 2D spaces for the massive galaxy population (M > 1010 M⊙) at z ∼ 0.6–1.0. Dn4000 and Hδ EWs primarily depend on stellar mass, but they also depend on environment at fixed stellar mass. By splitting the sample into centrals and satellites, and in terms of star-forming galaxies and quiescent galaxies, we reveal that the significant environmental trends of Dn4000 and Hδ EW, when controlling for stellar mass, are driven by quiescent galaxies. Regardless of being centrals or satellites, star-forming galaxies reveal Dn4000 and Hδ EWs, which depend strongly on their stellar mass and are completely independent of the environment at 0.6 < z < 1.0. The environmental trends seen for satellite galaxies are fully driven by the trends that hold only for quiescent galaxies, combined with the strong environmental dependency of the quiescent fraction at fixed stellar mass. Our results are consistent with recent predictions from simulations that point toward massive galaxies forming first in overdensities or the most compact dark matter haloes."}],"publication_status":"published","oa":1,"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2112.08372"}],"volume":926,"article_type":"original","oa_version":"Published Version","year":"2022","date_updated":"2022-07-19T09:37:42Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","scopus_import":"1","external_id":{"arxiv":["2112.08372"]},"publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]}},{"external_id":{"arxiv":["2102.04561"]},"scopus_import":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2022-07-19T09:38:03Z","publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"article_type":"original","year":"2022","oa_version":"Published Version","volume":924,"publication_status":"published","main_file_link":[{"url":"https://arxiv.org/abs/2102.04561","open_access":"1"}],"oa":1,"article_number":"73","abstract":[{"text":"The ratio of α-elements to iron in galaxies holds valuable information about the star formation history (SFH) since their enrichment occurs on different timescales. The fossil record of stars in galaxies has mostly been excavated for passive galaxies, since the light of star-forming galaxies is dominated by young stars, which have much weaker atmospheric absorption features. Here we use the largest reference cosmological simulation of the EAGLE project to investigate the origin of variations in stellar α-enhancement among star-forming galaxies at z = 0, and their impact on integrated spectra. The definition of α-enhancement in a composite stellar population is ambiguous. We elucidate two definitions—termed “mean” and “galactic” α-enhancement—in more detail. While a star-forming galaxy has a high “mean” α-enhancement when its stars formed rapidly, a galaxy with a large “galactic” α-enhancement generally had a delayed SFH. We find that absorption-line strengths of Mg and Fe correlate with variations in α-enhancement. These correlations are strongest for the “galactic” α-enhancement. However, we show that these are mostly caused by other effects that are cross-correlated with α-enhancement, such as variations in the light-weighted age. This severely complicates the retrieval of α-enhancements in star-forming galaxies. The ambiguity is not severe for passive galaxies, and we confirm that spectral variations in these galaxies are caused by measurable variations in α-enhancements. We suggest that this more complex coupling between α-enhancement and SFHs can guide the interpretation of new observations of star-forming galaxies.","lang":"eng"}],"_id":"11511","date_published":"2022-01-13T00:00:00Z","arxiv":1,"article_processing_charge":"No","issue":"2","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"language":[{"iso":"eng"}],"doi":"10.3847/1538-4357/ac350b","acknowledgement":"We thank our anonymous referee for the constructive feedback.

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.

In many systems, similar environmental contrasts occur repeatedly, sometimes driving parallel phenotypic evolution. Understanding the genomic basis of local adaptation and parallel evolution is a major goal of evolutionary genomics. It is now known that by preventing the break-up of favourable combinations of alleles across multiple loci, genetic architectures that reduce recombination, like chromosomal inversions, can make an important contribution to local adaptation. However, little is known about whether inversions also contribute disproportionately to parallel evolution. Our aim here is to highlight this knowledge gap, to showcase existing studies, and to illustrate the differences between genomic architectures with and without inversions using simple models. We predict that by generating stronger effective selection, inversions can sometimes speed up the parallel adaptive process or enable parallel adaptation where it would be impossible otherwise, but this is highly dependent on the spatial setting. We highlight that further empirical work is needed, in particular to cover a broader taxonomic range and to understand the relative importance of inversions compared to genomic regions without inversions.","lang":"eng"}],"_id":"11546","date_published":"2022-08-01T00:00:00Z","issue":"1856","article_processing_charge":"Yes (via OA deal)"},{"issue":"1","article_processing_charge":"No","_id":"11551","date_published":"2022-06-23T00:00:00Z","abstract":[{"text":"Imbalanced mitochondrial dNTP pools are known players in the pathogenesis of multiple human diseases. Here we show that, even under physiological conditions, dGTP is largely overrepresented among other dNTPs in mitochondria of mouse tissues and human cultured cells. In addition, a vast majority of mitochondrial dGTP is tightly bound to NDUFA10, an accessory subunit of complex I of the mitochondrial respiratory chain. NDUFA10 shares a deoxyribonucleoside kinase (dNK) domain with deoxyribonucleoside kinases in the nucleotide salvage pathway, though no specific function beyond stabilizing the complex I holoenzyme has been described for this subunit. We mutated the dNK domain of NDUFA10 in human HEK-293T cells while preserving complex I assembly and activity. The NDUFA10E160A/R161A shows reduced dGTP binding capacity in vitro and leads to a 50% reduction in mitochondrial dGTP content, proving that most dGTP is directly bound to the dNK domain of NDUFA10. This interaction may represent a hitherto unknown mechanism regulating mitochondrial dNTP availability and linking oxidative metabolism to DNA maintenance.","lang":"eng"}],"file":[{"date_created":"2022-07-13T07:44:58Z","success":1,"content_type":"application/pdf","relation":"main_file","file_id":"11571","checksum":"965f88bbcef3fd0c3e121340555c4467","date_updated":"2022-07-13T07:44:58Z","access_level":"open_access","file_name":"2022_communicationsbiology_Molina-Granada.pdf","creator":"kschuh","file_size":2335369}],"article_number":"620","oa":1,"publication_status":"published","volume":5,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"file_date_updated":"2022-07-13T07:44:58Z","oa_version":"Published Version","year":"2022","has_accepted_license":"1","publication_identifier":{"eissn":["23993642"]},"date_updated":"2023-08-03T11:51:58Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","scopus_import":"1","external_id":{"pmid":[" 35739187"],"isi":["000815098500002"]},"date_created":"2022-07-10T22:01:52Z","month":"06","isi":1,"publisher":"Springer Nature","status":"public","intvolume":"         5","department":[{"_id":"LeSa"}],"quality_controlled":"1","publication":"Communications Biology","title":"Most mitochondrial dGTP is tightly bound to respiratory complex I through the NDUFA10 subunit","citation":{"short":"D.

Our observations show that the D2 molecules inside helium nanodroplets essentially rotate as free D2 molecules.","lang":"eng"}],"date_published":"2022-06-16T00:00:00Z","article_number":"243201","issue":"24","article_processing_charge":"No","arxiv":1,"doi":"10.1103/PhysRevLett.128.243201","language":[{"iso":"eng"}],"project":[{"_id":"2688CF98-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"801770","name":"Angulon: physics and applications of a new quasiparticle"},{"name":"International IST Doctoral Program","grant_number":"665385","call_identifier":"H2020","_id":"2564DBCA-B435-11E9-9278-68D0E5697425"}],"type":"journal_article","author":[{"full_name":"Qiang, Junjie","first_name":"Junjie","last_name":"Qiang"},{"last_name":"Zhou","full_name":"Zhou, Lianrong","first_name":"Lianrong"},{"first_name":"Peifen","full_name":"Lu, Peifen","last_name":"Lu"},{"first_name":"Kang","full_name":"Lin, Kang","last_name":"Lin"},{"last_name":"Ma","first_name":"Yongzhe","full_name":"Ma, Yongzhe"},{"last_name":"Pan","full_name":"Pan, Shengzhe","first_name":"Shengzhe"},{"last_name":"Lu","first_name":"Chenxu","full_name":"Lu, Chenxu"},{"first_name":"Wenyu","full_name":"Jiang, Wenyu","last_name":"Jiang"},{"full_name":"Sun, Fenghao","first_name":"Fenghao","last_name":"Sun"},{"full_name":"Zhang, Wenbin","first_name":"Wenbin","last_name":"Zhang"},{"last_name":"Li","first_name":"Hui","full_name":"Li, Hui"},{"full_name":"Gong, Xiaochun","first_name":"Xiaochun","last_name":"Gong"},{"last_name":"Averbukh","full_name":"Averbukh, Ilya Sh","first_name":"Ilya Sh"},{"last_name":"Prior","full_name":"Prior, Yehiam","first_name":"Yehiam"},{"last_name":"Schouder","first_name":"Constant A.","full_name":"Schouder, Constant A."},{"last_name":"Stapelfeldt","first_name":"Henrik","full_name":"Stapelfeldt, Henrik"},{"id":"339C7E5A-F248-11E8-B48F-1D18A9856A87","first_name":"Igor","full_name":"Cherepanov, Igor","last_name":"Cherepanov"},{"orcid":"0000-0002-6990-7802","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","full_name":"Lemeshko, Mikhail","first_name":"Mikhail","last_name":"Lemeshko"},{"last_name":"Jäger","full_name":"Jäger, Wolfgang","first_name":"Wolfgang"},{"first_name":"Jian","full_name":"Wu, Jian","last_name":"Wu"}],"day":"16","title":"Femtosecond rotational dynamics of D2 molecules in superfluid helium nanodroplets","ec_funded":1,"citation":{"apa":"Qiang, J., Zhou, L., Lu, P., Lin, K., Ma, Y., Pan, S., … Wu, J.

They are a generalization of polynomial-like mapping, where the domain of the return map can have infinitely many components. They turned out to be extremely useful in tackling diverse problems. The purpose of this paper is:\r\n• To illustrate some pathologies that can occur when a complex box mapping is not induced by a globally defined map and when its domain has infinitely many components, and to give conditions to avoid these issues.\r\n• To show that once one has a box mapping for a rational map, these conditions can be assumed to hold in a very natural setting. Thus, we call such complex box mappings dynamically natural. Having such box mappings is the first step in tackling many problems in one-dimensional dynamics.\r\n• Many results in holomorphic dynamics rely on an interplay between combinatorial and analytic techniques. In this setting, some of these tools are:\r\n  • the Enhanced Nest (a nest of puzzle pieces around critical points) from Kozlovski, Shen, van Strien (AnnMath 165:749–841, 2007), referred to below as KSS;\r\n  • the Covering Lemma (which controls the moduli of pullbacks of annuli) from Kahn and Lyubich (Ann Math 169(2):561–593, 2009);\r\n   • the QC-Criterion and the Spreading Principle from KSS.\r\nThe purpose of this paper is to make these tools more accessible so that they can be used as a ‘black box’, so one does not have to redo the proofs in new settings.\r\n• To give an intuitive, but also rather detailed, outline of the proof from KSS and Kozlovski and van Strien (Proc Lond Math Soc (3) 99:275–296, 2009) of the following results for non-renormalizable dynamically natural complex box mappings:\r\n   • puzzle pieces shrink to points,\r\n   • (under some assumptions) topologically conjugate non-renormalizable polynomials and box mappings are quasiconformally conjugate.\r\n• We prove the fundamental ergodic properties for dynamically natural box mappings. This leads to some necessary conditions for when such a box mapping supports a measurable invariant line field on its filled Julia set. These mappings\r\nare the analogues of Lattès maps in this setting.\r\n• We prove a version of Mañé’s Theorem for complex box mappings concerning expansion along orbits of points that avoid a neighborhood of the set of critical points."}],"issue":"2","article_processing_charge":"No","file_date_updated":"2022-07-12T10:04:55Z","volume":8,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"publication_status":"published","oa":1,"day":"01","type":"journal_article","author":[{"full_name":"Clark, Trevor","first_name":"Trevor","last_name":"Clark"},{"orcid":"0000-0002-9156-8616","id":"fe8209e2-906f-11eb-847d-950f8fc09115","first_name":"Kostiantyn","full_name":"Drach, Kostiantyn","last_name":"Drach"},{"last_name":"Kozlovski","full_name":"Kozlovski, Oleg","first_name":"Oleg"},{"last_name":"Strien","full_name":"Strien, Sebastian Van","first_name":"Sebastian Van"}],"ec_funded":1,"citation":{"short":"T.
