By additional 13C,2H-labeling of residues other than valine and leucine residues of the protein, important chemical shift information about neighboring residues (following valine and leucine residues) can be achieved. Thus, different valine and leucine residues in a protein can be characterized as a specific chemical shift vector. Frequency matching with predicted chemical shifts via UCBShift 2.0 using experimental data taken from a subset of the BMRB database revealed a correct assignment performance of about 90%.

Photometric samples were constructed from varying selection criteria with limited spectroscopic follow-up available to test intrinsic spectral shapes and the prevalence of broad emission lines. We used the RUBIES survey, a large spectroscopic program with wide color-morphology coverage and homogeneous data quality, to systematically analyze the emission-line kinematics, spectral shapes, and morphologies of ∼1500 galaxies at z > 3.1. We identified broad Balmer lines via a novel fitting approach that simultaneously models NIRSpec/PRISM and G395M spectra, yielding 80 broad-line sources with 28 (35%) at z > 6. A large subpopulation naturally emerged from the broad Balmer line sources, with 36 exhibiting v-shaped UV-to-optical continua and a dominant point source component in the rest-optical; we define these as spectroscopic LRDs, constituting the largest such sample to date. Strikingly, the spectroscopic LRD population is largely recovered when either a broad line or rest-optical point source is required in combination with a v-shaped continuum, suggesting an inherent link between these three defining characteristics. We compared the spectroscopic LRD sample to published photometric searches. Although these selections have high accuracy, 80%−95% down to F444W < 26.5, only 50%−80% of the RUBIES LRDs were photometrically identified, depending on the selection criteria used. The remainder were missed due to a mixture of faint rest-UV photometry, comparatively blue rest-optical colors, or highly uncertain photometric redshifts. Our findings highlight that well-selected spectroscopic campaigns are essential for robust LRD identification, while photometric criteria require refinement to capture the full population.","lang":"eng"}],"external_id":{"isi":["001589731300022"]},"author":[{"full_name":"Hviding, Raphael E.","last_name":"Hviding","first_name":"Raphael E."},{"first_name":"Anna","last_name":"de Graaff","full_name":"de Graaff, Anna"},{"first_name":"Tim B.","last_name":"Miller","full_name":"Miller, Tim B."},{"full_name":"Setton, David J.","last_name":"Setton","first_name":"David J."},{"full_name":"Greene, Jenny E.","last_name":"Greene","first_name":"Jenny E."},{"full_name":"Labbé, Ivo","last_name":"Labbé","first_name":"Ivo"},{"full_name":"Brammer, Gabriel","first_name":"Gabriel","last_name":"Brammer"},{"full_name":"Bezanson, Rachel","last_name":"Bezanson","first_name":"Rachel"},{"full_name":"Boogaard, Leindert A.","first_name":"Leindert A.","last_name":"Boogaard"},{"full_name":"Cleri, Nikko J.","last_name":"Cleri","first_name":"Nikko J."},{"full_name":"Leja, Joel","last_name":"Leja","first_name":"Joel"},{"full_name":"Maseda, Michael V.","last_name":"Maseda","first_name":"Michael V."},{"full_name":"McConachie, Ian","last_name":"McConachie","first_name":"Ian"},{"last_name":"Matthee","first_name":"Jorryt J","id":"7439a258-f3c0-11ec-9501-9df22fe06720","orcid":"0000-0003-2871-127X","full_name":"Matthee, Jorryt J"},{"first_name":"Rohan P.","last_name":"Naidu","full_name":"Naidu, Rohan P."},{"last_name":"Oesch","first_name":"Pascal A.","full_name":"Oesch, Pascal A."},{"last_name":"Wang","first_name":"Bingjie","full_name":"Wang, Bingjie"},{"last_name":"Whitaker","first_name":"Katherine E.","full_name":"Whitaker, Katherine E."},{"full_name":"Williams, Christina C.","last_name":"Williams","first_name":"Christina C."}],"department":[{"_id":"JoMa"}],"PlanS_conform":"1","oa_version":"Published Version","_id":"20544","oa":1,"article_type":"original"},{"article_processing_charge":"Yes","quality_controlled":"1","publication":"Monthly Notices of the Royal Astronomical Society","month":"09","language":[{"iso":"eng"}],"publisher":"Oxford University Press","OA_place":"publisher","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"intvolume":" 543","date_published":"2025-09-25T00:00:00Z","citation":{"mla":"Komori, Fuga, et al. “The First Direct Imaging of the Silhouette of a Damped Lyman α System along the Line-of-Sight to a Background Galaxy.” Monthly Notices of the Royal Astronomical Society, vol. 543, no. 3, Oxford University Press, 2025, pp. 2943–57, doi:10.1093/mnras/staf1622.","ieee":"F.

Observing DLAs against spatially extended background galaxies provides a new method for constraining their size and structure. Using the Keck Cosmic Web Imager, we present the first ‘silhouette’ image of a DLA at $z=3.34$, identified in the spectrum of a background galaxy at $z=3.61$. Although the silhouette remains unresolved due to limited spatial resolution, this represents a successful proof-of-concept for studying DLA morphology using extended background sources. Possible residual emission in the DLA trough suggests an optical depth contrast exceeding $10^7$ in the internal structure, implying a sharp edge or patchy structure. A Lyman $\\alpha$ emitter (LAE) at $z_{\\rm LAE}=3.3433\\pm 0.0005$, consistent with the DLA redshift, is detected at an angular separation of $1{{_{.}^{\\prime\\prime}} }73\\pm 0{{_{.}^{\\prime\\prime}} }28$ ($12.9\\pm 2.1$ kpc). The DLA is surrounded by three galaxies within 140 kpc in projected distance and 500 km s$^{-1}$ in line-of-sight velocity, indicating that it resides in the circumgalactic medium of the LAE or within a galaxy group/protocluster environment. An O i $\\lambda 1302$ absorption at $z_{\\rm OI}=3.3288\\pm 0.0004$ is also detected along the line of sight. This absorber may trace metal-enriched outflow from the LAE or a gas-rich galaxy exhibiting the highest star formation activity among the surrounding galaxies. Future large spectroscopic surveys of galaxies will expand such a DLA sample, and three-dimensional spectroscopy for it will shed new light on the role of intergalactic dense gas in galaxy formation and evolution.","lang":"eng"}],"author":[{"full_name":"Komori, Fuga","first_name":"Fuga","last_name":"Komori"},{"last_name":"Inoue","first_name":"Akio K","full_name":"Inoue, Akio K"},{"full_name":"Mawatari, Ken","first_name":"Ken","last_name":"Mawatari"},{"full_name":"Sugahara, Yuma","last_name":"Sugahara","first_name":"Yuma"},{"full_name":"Umehata, Hideki","last_name":"Umehata","first_name":"Hideki"},{"full_name":"Shimakawa, Rhythm","last_name":"Shimakawa","first_name":"Rhythm"},{"first_name":"Satoshi","last_name":"Yamanaka","full_name":"Yamanaka, Satoshi"},{"last_name":"Hashimoto","first_name":"Takuya","full_name":"Hashimoto, Takuya"},{"first_name":"Jorryt J","last_name":"Matthee","full_name":"Matthee, Jorryt J","orcid":"0000-0003-2871-127X","id":"7439a258-f3c0-11ec-9501-9df22fe06720"},{"full_name":"Misawa, Toru","last_name":"Misawa","first_name":"Toru"}],"external_id":{"isi":["001592326700001"]},"department":[{"_id":"JoMa"}],"PlanS_conform":"1","oa_version":"Published Version","_id":"20545","oa":1,"article_type":"original","page":"2943-2957","isi":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file":[{"date_created":"2025-10-27T09:06:51Z","checksum":"d3190e974ce771e96c4c16ee98abb82a","creator":"dernst","success":1,"access_level":"open_access","content_type":"application/pdf","file_id":"20549","relation":"main_file","file_size":4864160,"date_updated":"2025-10-27T09:06:51Z","file_name":"2025_MonthlyNoticesRAS_Komori.pdf"}],"publication_status":"published","year":"2025","volume":543,"date_updated":"2025-12-01T15:07:43Z","file_date_updated":"2025-10-27T09:06:51Z"},{"ddc":["550"],"corr_author":"1","scopus_import":"1","publication_identifier":{"issn":["1866-3516"]},"OA_type":"gold","title":"DebDaB: A database of supraglacial debris thickness and physical properties","issue":"8","DOAJ_listed":"1","acknowledgement":"This work was supported by SNF project RENOIR (“Resolving the thickness of debris on Earth’s glaciers and its rate of change”; grant no. 204322).

Accurate representation of debris in models is challenging, as measurements of the physical properties and thickness of the supraglacial debris layer are scarce. Here, we compile a database of measured and reported bulk physical properties and layer thicknesses of supraglacial debris that we call the supraglacial Debris Database (DebDaB) and that is open to community submissions. The majority of the database (90 %) is compiled from 172 sources in the literature, and the remaining 10 % was previously unpublished. DebDaB contains 8741 data entries for supraglacial debris layer thickness, of which 1770 entries also include sub-debris ablation rates, 179 thermal conductivity of debris, 160 aerodynamic surface roughness length, 79 debris albedo, 59 debris emissivity, and 37 debris porosity. The data are distributed over 84 glaciers in 13 regions in the Global Terrestrial Network for Glaciers. We show regional differences in the distribution of debris thickness measurements in DebDaB and fit simplified Østrem curves to 19 glaciers with sufficient debris thickness and ablation data. The data in DebDaB can be used for energy balance, melt, and surface mass balance studies by incorporating site-specific debris properties or for evaluation of remote sensing estimates of debris thickness and surface roughness. They can also help future field campaigns on debris-covered glaciers by identifying observation gaps. DebDaB's uneven spatial coverage points to sampling biases in community efforts to observe debris-covered glaciers, with some regions (e.g. central Europe and South Asia) well-sampled but others having gaps with prevalent debris (e.g. the Andes and Alaska). Debris thickness measurements are mostly concentrated at lower elevations, leaving higher-elevation debris-covered areas undersampled and suggesting that our knowledge of debris properties might not be representative of all elevations. The aims of DebDaB, as an openly available dataset, are to evolve over time, to be updated, and to add to community submissions as new data on supraglacial properties become available. The data described in this paper can be accessed from Zenodo at https://doi.org/10.5281/zenodo.14224835 (Groeneveld et al., 2025)."}]},{"oa_version":"Published Version","_id":"20547","oa":1,"citation":{"ieee":"L.

This thesis explores geometric structures and dynamics on this space, with emphasis on their implications for physics, particularly hydrodynamics.\r\n\r\nOur investigation ranges from theoretical studies of infinite-dimensional symplectic and prequantum geometry to numerical computation of the time evolution of shapes. The thesis presents four main contributions.\r\n\r\nIn the first part, we introduce implicit representations of codimension-2 shapes using a class of complex-valued functions, and prove that the space of these implicit representations forms a prequantum bundle over the codimension-2 shape space. This reveals a new geometric interpretation of the canonical symplectic structure on the codimension-2 shape space.\r\n\r\nIn the second part, we use implicit representations to develop a simulation method for the dynamics of space curves. To handle chaotic systems such as vortex filaments in hydrodynamics, we exploit the infinite degrees of freedom, hidden in both the configuration and dynamics of implicit representations.\r\n\r\nIn the third part, we introduce new symplectic structures on the space of space curves, which generalize the only previously known symplectic structure on this space, allowing for new Hamiltonian dynamics of space curves.\r\n\r\nIn the fourth part, we apply a symplectic viewpoint to a differential geometric problem with practical applications.

(CRYPTO'18) are functions that require a prescribed number of sequential steps T to evaluate, yet their output can be verified in time much faster than T. Since their introduction, VDFs have gained a lot of attention due to their applications in blockchain protocols, randomness beacons, timestamping and deniability. This thesis explores the theory and applications of VDFs, focusing on enhancing their soundness, efficiency and practicality.\r\n\r\nThe only practical VDFs known to date are based on repeated squaring in hidden order groups. Consider the function VDF(x,T)=x^(2^T).\r\nThe iterated squaring assumption states that, for a random group element x, the result of VDF cannot be computed significantly faster than performing T sequential squarings if the group order is unknown. To make the result verifiable a prover can compute a proof of exponentiation (PoE) \\pi. Given \\pi, the output of VDF can be verified in time much less than T.\r\n\r\nWe first present new constructions of statistically sound proofs of exponentiation, which are an important building block in the construction of SNARKs (Succinct Non-Interactive Argument of Knowledge). Statistical soundness means that the proofs remain secure against computationally unbounded adversaries, in particular, it remains secure even when the group order is known. We thereby address limitations in previous PoE protocols which either required (non-standard) hardness assumptions or a lot of parallel repetitions. Our construction significantly reduces the proof size of statistically sound PoEs that allow for a structured exponent, which leads to better efficiency of SNARKs and other applications.\r\n\r\nSecondly, we introduce improved batching techniques for PoEs, which allow multiple proofs to be aggregated and verified with minimal overhead. These protocols optimize communication and computation complexity in large-scale blockchain environments and enable scalable remote benchmarking of parallel computation resources.\r\n\r\nWe then construct VDFs with enhanced properties such as zero-knowledge and watermarkability. It was shown by Arun, Bonneau and Clark (ASIACRYPT'22) that these features enable new cryptographic primitives called short-lived proofs and signatures. The validity of such proofs and signatures expires after a predefined amount of time T, i.e., they are deniable after time T. Our constructions improve upon the constructions by Arun, Bonneau and Clark in several dimensions (faster forging times, arguably weaker assumptions).\r\n\r\nFinally, we apply PoEs in the realm of primality testing, providing cryptographically sound proofs of non-primality for large Proth numbers. This work gives a surprising application of VDFs in the area of computational number theory.\r\n\r\nTogether, our contributions advance both the theoretical foundations and the real-world usability of VDFs in general and in particular of PoEs, making them more adaptable and secure for current and emerging cryptographic applications."}],"author":[{"first_name":"Charlotte","last_name":"Hoffmann","full_name":"Hoffmann, Charlotte","orcid":"0000-0003-2027-5549","id":"0f78d746-dc7d-11ea-9b2f-83f92091afe7"}],"page":"116","oa_version":"Published Version","_id":"20556"},{"title":"Universality in random matrices with spatial structure","corr_author":"1","ddc":["515","519"],"publication_identifier":{"isbn":["978-3-99078-064-0"],"issn":["2663-337X"]},"has_accepted_license":"1","status":"public","date_created":"2025-10-29T19:12:24Z","doi":"10.15479/AT-ISTA-20575","acknowledgement":"The work comprising this thesis was supported by the ERC Advanced Grant \"RMTBeyond\"\r\nNo.101020331 awarded to my advisor.","type":"dissertation","day":"3","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_published":"2025-11-03T00:00:00Z","citation":{"short":"V.

We consider both mean-field models with a general variance profile (Wigner-type matrices) and correlation structure (correlated matrices) among the entries, as well as non-mean-field random band matrices with bandwidth W >> N^(1/2).\r\n\r\nTo extract the universal properties of random matrix spectra and eigenvectors, we obtain concentration estimates for their resolvent, the local laws, which generalize the celebrated Wigner semicircle law for a broad class of random matrices to much finer spectral scales. The local laws hold for both a single resolvent as well as for products of multiple resolvents, known as resolvent chains, and express the remarkable approximately-deterministic behavior of these objects down to the microscopic scale.\r\n\r\nOur primary tool for establishing the local laws is the dynamical Zigzag strategy, which we develop in the setting of spatially-inhomogeneous random matrices. Our proof method systematically addresses the challenges arising from non-trivial spatial structures and is robust to all types of singularities in the spectrum, as we demonstrate in the correlated setting. Furthermore, we incorporate the analysis of the deterministic resolvent chain approximations into the dynamical framework of the Zigzag strategy, synthesizing a unified toolkit for establishing multi-resolvent local laws.\r\n\r\nUsing these methods, we prove complete eigenvector delocalization, the Eigenstate Thermalization Hypothesis, and Wigner-Dyson universality in the bulk for random band matrices down to the optimal bandwidth W >> N^(1/2). For mean-field ensembles, we establish universality of local eigenvalue statistics at the cups for random matrices with correlated entries, and the Eigenstate Thermalization Hypothesis for Wigner-type matrices in the bulk of the spectrum.\r\n\r\nFinally, this thesis also contains other applications of the multi-resolvent local laws to spatially-inhomogeneous random matrices, obtained prior to the development of the Zigzag strategy. In particular, we provide a complete analysis of mesoscopic linear-eigenvalue statistics of Wigner-type matrices in all spectral regimes, including the novel cusps, and rigorously establish the prethermalization phenomenon for deformed Wigner matrices.\r\n\r\nThe main body of this thesis consists of seven research papers (listed on page xi), each presented in a separate chapter with its own introduction and all relevant context, suitable to be read independently. We ask the reader’s indulgence for the repetitions in the historical overviews and other minor redundancies that remain among the chapters as a result.

In this regime, we show that, in the bulk spectrum, the eigenfunctions are fully delocalized, the eigenvalues follow the universal Wigner-Dyson statistics, and quantum unique ergodicity holds for general diagonal observables with an optimal convergence rate. Our results are valid for general variance profiles, arbitrary single entry distributions, in both real-symmetric and complex-Hermitian symmetry classes. In particular, our work substantially generalizes the recent breakthrough result of Yau and Yin [arXiv:2501.01718], obtained for a specific complex Hermitian Gaussian block band matrix. The main technical input is the optimal multi-resolvent local laws -- both in the averaged and fully isotropic form. We also generalize the $\\sqrtη$-rule from [arXiv:2012.13215] to exploit the additional effect of traceless observables.

We find a predominant period of 4.9704 hr, consistent with an orbit near the Roche limit of the white dwarf, with individual dips over 30% deep and lasting between 15 and 40 minutes. Similar to the first known white dwarf with transiting debris, WD 1145+017, the transit events are well-defined with prominent out-of-transit phases where the white dwarf appears unobscured. Spectroscopy concurrent with transit photometry reveals that the average Ca K equivalent width remains constant in and out of transit. The broadening observed in several absorption features cannot be reproduced by synthetic photospheric models, suggesting the presence of circumstellar gas. Simultaneous g + r- and g + i-band light curves from the CHIMERA instrument reveal no color dependence to the transit depths, requiring transiting dust grains to have sizes s ≳ 0.2 μm. The transit morphologies appear to be constantly changing at a rate faster than the orbital period. Overall transit activity varies in the system, with transit features completely disappearing during the seven months between our 2023 and 2024 observing seasons and then reappearing in 2025 March, still repeating at 4.9704 hr. Our observations of the complete cessation and resumption of transit activity provide a novel laboratory for constraining the evolution of disrupted debris and processes like disk exhaustion and replenishment timescales at white dwarfs.","lang":"eng"}],"PlanS_conform":"1","department":[{"_id":"IlCa"}],"date_updated":"2026-02-16T12:43:29Z","file_date_updated":"2025-11-04T12:33:51Z","file":[{"success":1,"creator":"dernst","checksum":"24892d1b5bfa1867eb0a353f10c31b82","date_created":"2025-11-04T12:33:51Z","access_level":"open_access","date_updated":"2025-11-04T12:33:51Z","file_size":5323398,"relation":"main_file","content_type":"application/pdf","file_id":"20601","file_name":"2025_AstrophysicalJour_Guidry.pdf"}],"isi":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":992,"year":"2025","publication_status":"published","article_number":"167","intvolume":" 992","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"citation":{"ista":"Guidry JA, Vanderbosch ZP, Hermes JJ, Veras D, Hollands MA, Bhattacharjee S, Caiazzo I, El-Badry K, Kao ML, Ould Rouis LB, Rodriguez AC, Van Roestel J. 2025.

When honest parties control a majority of the work, consensus is achieved by picking the chain with the highest recorded weight. Resources other than work have been considered to secure such longest-chain blockchains. In Chia, blocks record the amount of disk-space S (via a proof of space) and sequential computational steps V (through a VDF).\r\nIn this paper, we ask what weight functions Γ(S,V,W) (that assign a weight to a block as a function of the recorded space, speed, and work) are secure in the sense that whenever the weight of the resources controlled by honest parties is larger than the weight of adversarial parties, the blockchain is secure against private double-spending attacks.\r\nWe completely classify such functions in an idealized \"continuous\" model: Γ(S,V,W) is secure against private double-spending attacks if and only if it is homogeneous of degree one in the \"timed\" resources V and W, i.e., αΓ(S,V,W) = Γ(S,α V, α W). This includes the Bitcoin rule Γ(S,V,W) = W and the Chia rule Γ(S,V,W) = S ⋅ V. In a more realistic model where blocks are created at discrete time-points, one additionally needs some mild assumptions on the dependency on S (basically, the weight should not grow too much if S is slightly increased, say linear as in Chia).\r\nOur classification is more general and allows various instantiations of the same resource. It provides a powerful tool for designing new longest-chain blockchains. E.g., consider combining different PoWs to counter centralization, say the Bitcoin PoW W₁ and a memory-hard PoW W₂. Previous work suggested to use W₁+W₂ as weight. Our results show that using e.g., √{W₁}⋅ √{W₂} or min{W₁,W₂} are also secure, and we argue that in practice these are much better choices."}],"alternative_title":["LIPIcs"],"file_date_updated":"2025-11-04T08:19:02Z","date_updated":"2026-04-15T08:45:18Z","volume":354,"year":"2025","publication_status":"published","related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"21651"}]},"file":[{"success":1,"creator":"dernst","checksum":"b638adcd4fbffa77116c35393e165eb7","date_created":"2025-11-04T08:19:02Z","access_level":"open_access","date_updated":"2025-11-04T08:19:02Z","file_size":1061847,"relation":"main_file","file_id":"20598","content_type":"application/pdf","file_name":"2025_LIPIcsAFT_Baig.pdf"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","isi":1,"file":[{"success":1,"creator":"dernst","checksum":"cc7d00c349d48458accb0d3df67e4879","date_created":"2025-11-04T08:26:39Z","access_level":"open_access","file_size":12677603,"date_updated":"2025-11-04T08:26:39Z","relation":"main_file","file_id":"20599","content_type":"application/pdf","file_name":"2025_PASP_BhattacharjeeS.pdf"}],"publication_status":"published","year":"2025","volume":137,"date_updated":"2025-12-01T15:13:50Z","file_date_updated":"2025-11-04T08:26:39Z","abstract":[{"lang":"eng","text":"In this second paper on our variability survey of central stars of planetary nebulae (CSPNe) using the Zwicky Transient Facility (ZTF), we report 11 long-timescale variables with variability timescales ranging from months to years. We also present preliminary analyses based on spectroscopic and/or photometric follow-up observations for six of them. Among them is NGC 6833, which shows a 980 days periodic variability with strange characteristics: “triangle-shaped” brightening in r, i, and WISE bands but almost coincidental shallow dips in the g-band. The most plausible explanation is a wide binary with the photometric period being the orbital period. Long-period near-sinusoidal variability was detected in two other systems, NGC 6905 and Kn 26, with periods of 700 days and 230 days, respectively, making them additional wide-binary candidates. The latter also shows a short period at 1.18 hr. We then present CTSS 2 and K 3-5, which show brightening and significant reddening over the whole ZTF baseline. A stellar model fit to the optical spectrum of CTSS 2 reveals it to be one of the youngest post-AGB CSPNe known. Both show high-density emission-line cores. We propose these to be late-thermal-pulse candidates, currently evolving towards the AGB phase. We then present recent HST/COS ultraviolet spectroscopy of the known wide-binary candidate LoTr 1, showing that the hot star is a spectroscopic twin of the extremely hot white dwarf in UCAC2 46706450. Similar to this object, LoTr 1 also has a fast rotating wide subgiant companion. We suggest that the long photometric period of 11 yr is the binary orbital period. Finally, we briefly discuss the ZTF light curves of the remaining variables, namely Tan 2, K 3-20, WHTZ 3, Kn J1857+3931, and IPHAS J1927+0814. With these examples, we present the effectiveness of the von Neumann statistics and Pearson Skew-based metric space in searching for long-timescale variables."}],"external_id":{"arxiv":["2502.18651"],"isi":["001595690000001"]},"author":[{"full_name":"Bhattacharjee, Soumyadeep","first_name":"Soumyadeep","last_name":"Bhattacharjee"},{"full_name":"Reindl, Nicole","last_name":"Reindl","first_name":"Nicole"},{"full_name":"Bond, Howard E.","first_name":"Howard E.","last_name":"Bond"},{"full_name":"Werner, Klaus","last_name":"Werner","first_name":"Klaus"},{"first_name":"Gregory R.","last_name":"Zeimann","full_name":"Zeimann, Gregory R."},{"full_name":"Jones, David","first_name":"David","last_name":"Jones"},{"last_name":"El-Badry","first_name":"Kareem","full_name":"El-Badry, Kareem"},{"last_name":"Mackensen","first_name":"Nina","full_name":"Mackensen, Nina"},{"full_name":"Chornay, Nicholas","first_name":"Nicholas","last_name":"Chornay"},{"full_name":"Kulkarni, S.

This paper investigates the star formation histories (SFHs) of a sample of massive galaxies (M⋆ ≥ 1010 M⊙) in the redshift range 1 < z < 4.5.\r\nMethods. We analyzed spectro-photometric data, combining broadband photometry from HST and JWST with low-resolution grism spectroscopy from JWST/NIRISS, obtained as part of the MIRI Deep Imaging Survey program. SFHs were derived through spectral energy distribution fitting using two independent codes, BAGPIPES and synthesizer, under various SFH assumptions. This approach enables a comprehensive assessment of the biases introduced by different modeling choices.\r\nResults. The inclusion of NIRISS spectroscopy, even with its low resolution, significantly improves constraints on key physical parameters, such as the mass-weighted stellar age (tM) and formation redshift (zform), by narrowing their posterior distributions. The massive galaxies in our sample exhibit rapid stellar mass assembly, forming 50% of their mass between 3 ≤ z ≤ 9. The highest inferred formation redshifts are compatible with elevated star formation efficiencies (ϵ) at early epochs. Nonparametric SFHs generally imply an earlier and slower mass assembly compared to parametric forms, highlighting the sensitivity of inferred formation timescales to the chosen SFH model–particularly for galaxies at z < 2. We find that quiescent galaxies are, on average, older (tM ∼ 1.1 Gyr) and assembled more rapidly at earlier times than their star-forming counterparts. These findings support the “downsizing” scenario, in which more massive and passive systems form earlier and more efficiently."}],"article_type":"original","oa":1,"_id":"20589","oa_version":"Published Version","volume":702,"year":"2025","publication_status":"published","file":[{"date_created":"2025-11-04T09:36:30Z","checksum":"0cd0c3fc75b7f6589088a2b7bd60c0ed","creator":"dernst","success":1,"access_level":"open_access","content_type":"application/pdf","file_id":"20600","relation":"main_file","date_updated":"2025-11-04T09:36:30Z","file_size":5107702,"file_name":"2025_AstronomyAstrophysics_Annunziatella.pdf"}],"isi":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file_date_updated":"2025-11-04T09:36:30Z","date_updated":"2026-02-16T12:14:12Z","OA_place":"publisher","publisher":"EDP Sciences","language":[{"iso":"eng"}],"month":"10","publication":"Astronomy & Astrophysics","quality_controlled":"1","article_processing_charge":"No","citation":{"short":"M.

It plays a central role in the weather and climate of the Tropics, where, to first order, the heating of the atmosphere by convection is in balance with the cooling of the atmosphere by the emission of radiation to outer space. In this study, we use a cloud-resolving model in radiative–convective equilibrium with an imposed constant rate of radiative cooling and study the response of moist convection to varying this rate of radiative cooling. In particular, we study two types of simulation: varying air temperature (VAT) simulations, where the air temperature is allowed to adjust to the imposed radiative cooling, and constant air temperature (CAT) simulations, where the surface temperature is tuned to ensure that the atmospheric temperature profile in the domain is constant. We recover the previously known result that, in response to increasing radiative cooling, the area of convection expands rapidly, while the intensity of convection does not change. We find that this response is explained by the increased boundary-layer variability in simulations with greater radiative cooling, which compensates for the decreasing temperature by adding a larger initial velocity close to the cloud base. We also propose a fundamental scaling of the non-dimensional cumulus mass flux in moist convection, which is robust across models of different complexity. We aim to bridge the gap between highly idealised prototypes of moist convection, such as the “Rainy–Bénard convection” introduced by Vallis et al., and comprehensive cloud-resolving models."}],"acknowledged_ssus":[{"_id":"ScienComp"}],"article_type":"original","oa":1,"_id":"20590","ec_funded":1,"project":[{"name":"IST-BRIDGE: International postdoctoral program","grant_number":"101034413","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","call_identifier":"H2020"},{"name":"Organization of CLoUdS, and implications of Tropical cyclones and for the Energetics of the tropics, in current and waRming climate","call_identifier":"H2020","_id":"629205d8-2b32-11ec-9570-e1356ff73576","grant_number":"805041"}],"oa_version":"Published Version","year":"2025","publication_status":"epub_ahead","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","isi":1,"date_updated":"2025-12-01T15:15:18Z"},{"tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"article_number":"71","intvolume":" 30","citation":{"mla":"Brigati, Giovanni, and Francesco Pedrotti. “Heat Flow, Log-Concavity, and Lipschitz Transport Maps.” Electronic Communications in Probability, vol. 30, 71, Institute of Mathematical Statistics, 2025, doi:10.1214/25-ECP717.","ieee":"G.

In practical applications, however, the underlying dynamical system often contains uncertain parameters, requiring the propagation of this model uncertainty to the ODE solution. In this paper, we demonstrate that ODE filters, despite their probabilistic nature, do not automatically solve this uncertainty propagation problem. To address this limitation, we present a novel approach that combines ODE filters with numerical quadrature to properly marginalize over uncertain parameters, while accounting for both parameter uncertainty and numerical solver uncertainty. Experiments across multiple dynamical systems demonstrate that the resulting uncertainty estimates closely match reference solutions. Notably, we show\r\nhow the numerical uncertainty from the ODE solver can help prevent overconfidence in the propagated uncertainty estimates, especially when using larger step sizes. Our results illustrate that probabilistic numerical methods can effectively quantify both numerical and parametric uncertainty in dynamical systems.

Although these terms are commonly used, their precise distinctions and impacts on key performance metrics, such as rate capability, energy density, and capacity fading, remain poorly understood. In this work, we employ operando small- and wide-angle X-ray scattering alongside cryogenic transmission electron microscopy (cryo-TEM) to compare Li–S batteries in sparingly solvating and solvating ether-based electrolytes. We find that, unlike solvating electrolytes, SPSEs lead to an extended presence of lithium sulfide during cycling, coexisting with sulfur at a 50% state of charge and beyond. In the charged state, solid sulfur is present in its amorphous form inside the carbon black nanopores. These findings indicate that the limited solubility confines polysulfides in regions near the carbon surface, where these polysulfides enable conversion between the coexisting solid discharge and charge product."}],"author":[{"full_name":"Dutta, Pronoy","first_name":"Pronoy","last_name":"Dutta"},{"first_name":"Jean Marc","last_name":"Von Mentlen","full_name":"Von Mentlen, Jean Marc"},{"id":"d25d21ef-dc8d-11ea-abe3-ec4576307f48","full_name":"Mondal, Soumyadip","last_name":"Mondal","first_name":"Soumyadip"},{"first_name":"Nikolaos","last_name":"Kostoglou","full_name":"Kostoglou, Nikolaos"},{"full_name":"Wilts, Bodo D.","first_name":"Bodo D.","last_name":"Wilts"},{"first_name":"Stefan Alexander","last_name":"Freunberger","orcid":"0000-0003-2902-5319","full_name":"Freunberger, Stefan Alexander","id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425"},{"last_name":"Zickler","first_name":"Gregor A.","full_name":"Zickler, Gregor A."},{"full_name":"Prehal, Christian","first_name":"Christian","last_name":"Prehal"}],"external_id":{"isi":["001600396000001"]},"file_date_updated":"2025-11-04T07:56:19Z","date_updated":"2025-12-01T15:11:44Z","publication_status":"published","volume":10,"year":"2025","isi":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file":[{"file_name":"2025_ACSEnergyLetters_Dutta.pdf","date_updated":"2025-11-04T07:56:19Z","file_size":9307654,"relation":"main_file","content_type":"application/pdf","file_id":"20597","access_level":"open_access","success":1,"creator":"dernst","checksum":"368eb041c395a5155218f858947df419","date_created":"2025-11-04T07:56:19Z"}],"related_material":{"link":[{"relation":"software","url":" https://doi.org/10.5281/zenodo.17144229"}]}}]
