One is the well-known Jensen–Shannon divergence, which is easy to compute and whose square root is a proper metric. The other is what we call the minmax divergence, which is harder to compute. Just like the Jensen–Shannon divergence, it arises naturally from the Kullback–Leibler divergence. The main contribution of this paper is a proof showing that the minmax divergence can be tightly approximated by the Jensen–Shannon divergence. The bounds suggest that the square root of the minmax divergence is a metric, and we prove that this is indeed true in the one-dimensional case. The general case remains open. Finally, we consider analogous questions in the context of another Bregman divergence and the corresponding Burbea–Rao (Jensen–Bregman) divergence.","lang":"eng"}],"ec_funded":1,"doi":"10.3390/e27080854","date_published":"2025-08-01T00:00:00Z","project":[{"name":"Alpha Shape Theory Extended","_id":"266A2E9E-B435-11E9-9278-68D0E5697425","grant_number":"788183","call_identifier":"H2020"},{"name":"Mathematics, Computer Science","call_identifier":"FWF","grant_number":"Z00342","_id":"268116B8-B435-11E9-9278-68D0E5697425"},{"call_identifier":"FWF","_id":"2561EBF4-B435-11E9-9278-68D0E5697425","grant_number":"I02979-N35","name":"Persistence and stability of geometric complexes"}],"ddc":["500"],"date_updated":"2025-09-30T14:32:31Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"volume":27,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","year":"2025","date_created":"2025-09-07T22:01:33Z","pmid":1,"citation":{"mla":"Akopyan, Arseniy, et al. “Tight Bounds between the Jensen–Shannon Divergence and the Minmax Divergence.” Entropy, vol. 27, no. 8, 854, MDPI, 2025, doi:10.3390/e27080854.","chicago":"Akopyan, Arseniy, Herbert Edelsbrunner, Ziga Virk, and Hubert Wagner. “Tight Bounds between the Jensen–Shannon Divergence and the Minmax Divergence.” Entropy.

Here we report two LRDs (ID9094 and ID2756) at zspec > 7 recently discovered in the JWST FRESCO GOODS-North field. Both satisfy the “v-shaped” color and compactness criteria for LRDs and are identified as Type-I AGN candidates based on their broad Hβ emission lines (full width at half maximum: 2280 ± 490 km s−1 for ID9094 and 1070 ± 240 km s−1 for ID2756) and narrow [O III] lines (≃300 − 400 km s−1). To investigate their nature, we conducted deep NOEMA follow-up observations targeting the [C II] 158 μm emission line and the 1.3 mm dust continuum. We do not detect [C II] or 1.3 mm continuum emission for either source. If the two LRDs were DSFGs, we would expect significant detections: > 16σ for [C II] and > 3σ for the 1.3 mm continuum of ID9094, and > 5σ for the [C II] of ID2756. Using the 3σ upper limits of [C II] and 1.3 mm, we performed two analyses: (1) UV-to-far-infrared spectral energy distribution fitting with and without AGN components, and (2) comparison of their properties with the L[C II]–SFRtot empirical relation. Both analyses are consistent with a scenario in which AGN activity contributes to the observed properties, though a dusty star-forming origin cannot be fully ruled out. Our results highlight the importance of far-infrared observations for studying LRDs, a regime that remains largely unexplored.","lang":"eng"}],"file_date_updated":"2025-09-08T07:40:53Z","intvolume":" 700","file":[{"access_level":"open_access","file_name":"2025_AstronomyAstrophysics_Xiao.pdf","file_size":3648334,"date_updated":"2025-09-08T07:40:53Z","creator":"dernst","date_created":"2025-09-08T07:40:53Z","content_type":"application/pdf","success":1,"checksum":"fab2168609078b8336be01ef13b3238e","file_id":"20308","relation":"main_file"}],"publication":"Astronomy & Astrophysics","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2025-09-07T22:01:33Z","year":"2025","ddc":["520"],"date_published":"2025-08-01T00:00:00Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"volume":700,"date_updated":"2026-02-16T12:12:36Z"},{"date_published":"2025-10-01T00:00:00Z","project":[{"call_identifier":"H2020","grant_number":"949120","_id":"0aa60e99-070f-11eb-9043-a6de6bdc3afa","name":"Tribocharge: a multi-scale approach to an enduring problem in physics"}],"ddc":["530"],"date_updated":"2025-12-30T09:31:25Z","volume":12,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2025-09-07T22:01:33Z","year":"2025","file_date_updated":"2025-12-30T09:31:11Z","publication":"Advanced Materials Interfaces","file":[{"relation":"main_file","file_id":"20908","checksum":"906fcc7733be8ce8a83600427b82cd5a","success":1,"content_type":"application/pdf","date_created":"2025-12-30T09:31:11Z","creator":"dernst","date_updated":"2025-12-30T09:31:11Z","file_name":"2025_AdvMaterialsInterfaces_Lenton.pdf","file_size":1830117,"access_level":"open_access"}],"intvolume":" 12","department":[{"_id":"ScWa"},{"_id":"NanoFab"}],"external_id":{"isi":["001560163400001"],"arxiv":["2506.07187"]},"publication_status":"published","doi":"10.1002/admi.202500521","abstract":[{"text":"Scanning Kelvin probe microscopy (SKPM) is a powerful technique for macroscopic imaging of the electrostatic potential above a surface. Though most often used to image work-function variations of conductive surfaces, it can also be used to probe the surface charge on insulating surfaces. In both cases, relating the measured potential to the underlying signal is non-trivial. Here, general relationships are derived between the measured SKPM voltage and the underlying source, revealing either can be cast as a convolution with an appropriately scaled point spread function (PSF). For charge that exists on a thin insulating layer above a conductor, the PSF has the same shape as what would occur from a work-function variation alone, differing by a simple scaling factor. This relationship is confirmed by: (1) backing it out from finite-element simulations of work-function and charge signals, and (2) experimentally comparing the measured PSF from a small work-function target to that from a small charge spot. This scaling factor is further validated by comparing SKPM charge measurements with Faraday cup measurements for highly charged samples from contact-charging experiments. These results highlight a heretofore unappreciated connection between SKPM voltage and charge signals, offering a rigorous recipe to extract either from experimental data.","lang":"eng"}],"ec_funded":1,"PlanS_conform":"1","_id":"20295","corr_author":"1","DOAJ_listed":"1","issue":"19","article_type":"original","article_processing_charge":"Yes","author":[{"orcid":"0000-0002-5010-6984","full_name":"Lenton, Isaac C","last_name":"Lenton","id":"a550210f-223c-11ec-8182-e2d45e817efb","first_name":"Isaac C"},{"first_name":"Felix","orcid":"0000-0003-0463-5794","full_name":"Pertl, Felix","last_name":"Pertl","id":"6313aec0-15b2-11ec-abd3-ed67d16139af"},{"first_name":"Lubuna B","id":"3CD37A82-F248-11E8-B48F-1D18A9856A87","full_name":"Shafeek, Lubuna B","orcid":"0000-0001-7180-6050","last_name":"Shafeek"},{"first_name":"Scott R","id":"3A1FFC16-F248-11E8-B48F-1D18A9856A87","last_name":"Waitukaitis","orcid":"0000-0002-2299-3176","full_name":"Waitukaitis, Scott R"}],"oa":1,"language":[{"iso":"eng"}],"OA_place":"publisher","status":"public","day":"01","type":"journal_article","article_number":"e00521","publisher":"Wiley","publication_identifier":{"eissn":["2196-7350"]},"quality_controlled":"1","month":"10","has_accepted_license":"1","arxiv":1,"citation":{"ista":"Lenton IC, Pertl F, Shafeek LB, Waitukaitis SR. 2025.

In the high-privacy regime (ϵ≤1\r\n), we identify an optimal privacy mechanism that minimizes the variance of the estimator asymptotically. Our main technical contribution is the maximization of the Fisher-Information of the sanitized data with respect to the local privacy mechanism Q. We find that the exact solution Qθ,ϵ of this maximization is the sign mechanism that applies randomized response to the sign of Xi−θ, where X1,…,Xn are the confidential iid original samples. However, since this optimal local mechanism depends on the unknown mean θ, we employ a two-stage LDP parameter estimation procedure which requires splitting agents into two groups. The first n1 observations are used to consistently but not necessarily efficiently estimate the parameter θ by θn1~\r\n. Then this estimate is updated by applying the sign mechanism with θ~n1 instead of θ\r\n to the remaining n−n1 observations, to obtain an LDP and efficient estimator of the unknown mean.","lang":"eng"}],"alternative_title":["PMLR"],"publication_status":"published","department":[{"_id":"ChLa"}],"external_id":{"arxiv":["2402.04840"]},"intvolume":" 258","file":[{"creator":"dernst","access_level":"open_access","date_updated":"2025-09-09T08:26:44Z","file_size":395864,"file_name":"2025_AISTATS_Kalinin.pdf","checksum":"3dcd59988ca974b98662ba09a516e616","file_id":"20316","relation":"main_file","date_created":"2025-09-09T08:26:44Z","content_type":"application/pdf","success":1}],"publication":"Proceedings of the 28th International Conference on Artificial Intelligence and Statistics","file_date_updated":"2025-09-09T08:26:44Z","year":"2025","date_created":"2025-09-07T22:01:34Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2025-09-09T08:28:41Z","volume":258,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"conference":{"location":"Mai Khao, Thailand","start_date":"2025-05-03","name":"AISTATS: Conference on Artificial Intelligence and Statistics","end_date":"2025-05-05"},"date_published":"2025-05-01T00:00:00Z","ddc":["000"]},{"date_created":"2025-09-07T22:01:34Z","year":"2025","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","conference":{"end_date":"2025-07-25","name":"UAI: Conference on Uncertainty in Artificial Intelligence","start_date":"2025-07-21","location":"Rio de Janeiro, Brazil"},"volume":286,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"date_updated":"2025-09-09T06:31:20Z","project":[{"_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","grant_number":"863818","call_identifier":"H2020","name":"Formal Methods for Stochastic Models: Algorithms and Applications"}],"ddc":["000"],"date_published":"2025-01-01T00:00:00Z","alternative_title":["PMLR"],"abstract":[{"text":"Deterministic Markov Decision Processes (DMDPs) are a mathematical framework for decision-making where the outcomes and future possible actions are deterministically determined by the current action taken. DMDPs can be viewed as a finite directed weighted graph, where in each step, the controller chooses an outgoing edge. An objective is a measurable function on runs (or infinite trajectories) of the DMDP, and the value for an objective is the maximal cumulative reward (or weight) that the controller can guarantee. We consider the classical mean-payoff (aka limit-average) objective, which is a basic and fundamental objective.\r\n\r\nHoward's policy iteration algorithm is a popular method for solving DMDPs with mean-payoff objectives. Although Howard's algorithm performs well in practice, as experimental studies suggested, the best known upper bound is exponential and the current known lower bound is as follows: For the input size I, the algorithm requires (math formular) iterations, where (math formular) hides the poly-logarithmic factors, i.e., the current lower bound on iterations is sub-linear with respect to the input size.

At the same time, data is often high-dimensional and costly to label. For a single objective such as prediction risk, conventional regularization techniques are known to improve generalization when the data exhibits low-dimensional structure like sparsity. However, it is largely unexplored how to leverage this structure in the context of multi-objective learning (MOL) with multiple competing objectives. In this work, we discuss how the application of vanilla regularization approaches can fail, and propose a two-stage MOL framework that can successfully leverage low-dimensional structure. We demonstrate its effectiveness experimentally for multi-distribution learning and fairness-risk trade-offs.","lang":"eng"}],"alternative_title":["PMLR"],"publication_status":"published","department":[{"_id":"MaMo"}],"external_id":{"arxiv":["2503.08849"]},"publication":"The 28th International Conference on Artificial Intelligence and Statistics","intvolume":" 258"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2025","date_created":"2025-09-07T22:01:35Z","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2302.11341","open_access":"1"}],"date_published":"2025-05-01T00:00:00Z","project":[{"name":"The design and evaluation of modern fully dynamic data structures","grant_number":"101019564","_id":"bd9ca328-d553-11ed-ba76-dc4f890cfe62","call_identifier":"H2020"},{"grant_number":"Z00422","_id":"34def286-11ca-11ed-8bc3-da5948e1613c","name":"Efficient algorithms"},{"grant_number":"I05982","_id":"bda196b2-d553-11ed-ba76-8e8ee6c21103","name":"Static and Dynamic Hierarchical Graph Decompositions"},{"_id":"bd9e3a2e-d553-11ed-ba76-8aa684ce17fe","grant_number":"P33775","name":"Fast Algorithms for a Reactive Network Layer"}],"date_updated":"2025-09-09T07:09:22Z","volume":258,"conference":{"end_date":"2025-05-05","name":"AISTATS: Conference on Artificial Intelligence and Statistics","start_date":"2025-05-03","location":"Mai Khao, Thailand"},"publication_status":"published","department":[{"_id":"MoHe"}],"external_id":{"arxiv":["2302.11341"]},"abstract":[{"lang":"eng","text":"We study privately releasing column sums of a d-dimensional table with entries from a universe χ undergoing T row updates, called histogram under continual release. Our mechanisms give better additive ℓ∞-error than existing mechanisms for a large class of queries and input streams. Our first contribution is an output-sensitive mechanism in the insertions-only model (χ = {0, 1}) for maintaining (i) the histogram or (ii) queries that do not require maintaining the entire histogram, such as the maximum or minimum column sum, the median, or any quantiles. The mechanism has an additive error of O(d log2 (dq∗) + log T) whp, where q∗ is the maximum output value over all time steps on this dataset. The mechanism does not require q∗ as input. This breaks the Ω(d log T) bound of prior work when q∗ ≪ T. Our second contribution is a mechanism for the turnstile model that admits negative entry updates (χ = {−1, 0, 1}). This mechanism has an additive error of O(d log2(dK) + log T) whp, where K is the number of times two consecutive data rows differ, and the mechanism does not require K as input. This is useful when monitoring inputs that only vary under unusual circumstances. For d = 1 this gives the first\r\nprivate mechanism with error O(log2 K + log T) for continual counting in the turnstile model, improving on the O(log2 n + log T) error bound by Dwork et al. (2015), where n is the number of ones in the stream, as well as allowing negative entries, while Dwork et al. (2015) can only handle nonnegative entries (χ = {0, 1}).

To maintain privacy, such data is often only publicly available as summary statistics, and often studies for the endogenous covariates and the outcome are available separately. This has necessitated methods tailored to two-sample summary statistics. Current state-of-the-art methods modify linear instrumental variable (IV) regression---with genetic variants as instruments---to account for unmeasured confounding. However, since the endogenous covariates can be high dimensional, standard IV assumptions are generally insufficient to identify all causal effects simultaneously. We ensure identifiability by assuming the causal effects are sparse and propose a sparse causal effect two-sample IV estimator, spaceTSIV, adapting the spaceIV estimator by Pfister and Peters (2022) for two-sample summary statistics. We provide two methods, based on L0- and L1-penalization, respectively. We prove identifiability of the sparse causal effects in the two-sample setting and consistency of spaceTSIV. The performance of spaceTSIV is compared with existing two-sample IV methods in simulations. Finally, we showcase our methods using real proteomic and gene-expression data for drug-target discovery.","lang":"eng"}],"alternative_title":["PMLR"],"publication":"The 28th International Conference on Artificial Intelligence and Statistics","intvolume":" 258"},{"author":[{"first_name":"Maitane","last_name":"Muñoz Basagoiti","orcid":"0000-0003-1483-1457","full_name":"Muñoz Basagoiti, Maitane","id":"1a8a7950-82cd-11ed-bd4f-9624c913a607"},{"first_name":"Felix F","full_name":"Frey, Felix F","orcid":"0000-0001-8501-6017","last_name":"Frey","id":"a0270b37-8f1a-11ec-95c7-8e710c59a4f3"},{"last_name":"Meadowcroft","orcid":"0000-0003-3441-1337","full_name":"Meadowcroft, Billie","id":"a4725fd6-932b-11ed-81e2-c098c7f37ae1","first_name":"Billie"},{"first_name":"Miguel","id":"4f2d02dd-47a9-11ec-ad10-82820ed3f501","full_name":"Santana de Freitas Amaral, Miguel","last_name":"Santana de Freitas Amaral"},{"last_name":"Prada","full_name":"Prada, Adam","id":"a43ed60a-dd22-11ed-9bf7-b34133792ea9","first_name":"Adam"},{"id":"bf63d406-f056-11eb-b41d-f263a6566d8b","last_name":"Šarić","orcid":"0000-0002-7854-2139","full_name":"Šarić, Anđela","first_name":"Anđela"}],"license":"https://creativecommons.org/licenses/by-nc/4.0/","oa":1,"language":[{"iso":"eng"}],"_id":"20318","corr_author":"1","issue":"40","article_processing_charge":"Yes (via OA deal)","article_type":"original","publication_identifier":{"issn":["1744-683X"],"eissn":["1744-6848"]},"publisher":"Royal Society of Chemistry","quality_controlled":"1","month":"07","status":"public","page":"7736-7756","OA_place":"publisher","type":"journal_article","day":"28","has_accepted_license":"1","citation":{"chicago":"Muñoz Basagoiti, Maitane, Felix F Frey, Billie Meadowcroft, Miguel Santana de Freitas Amaral, Adam Prada, and Anđela Šarić. “A Tutorial for Mesoscale Computer Simulations of Lipid Membranes: Tether Pulling, Tubulation and Fluctuations.” Soft Matter.

In this review, we introduce the non-expert reader to coarse-grained membrane simulations at the mesoscale. Firstly, we give a concise overview of the modelling approaches to study fluid membranes, together with guidance to more specialized references. Secondly, we provide a conceptual guide on how to develop mesoscale membrane simulations. Lastly, we construct a hands-on tutorial on how to apply mesoscale membrane simulations, by providing a pedagogical examination of membrane tether pulling, shape and mechanics of membrane tubes, and membrane fluctuations with three different membrane models, and discussing them in terms of their scope and how resource-intensive they are.

Observational evidence suggests that is generally longer than 1 hr. Further, continental and oceanic convection are different in terms of the vigor of updrafts and can have different longevities. So using hour worldwide in CAM has two potential caveats. A longer improves the simulation of the mean climate. However, it does not address the land‐ocean heterogeneity of atmospheric deep convection. We investigate the prescription of two different CAPE relaxation timescales for land ( hr) and ocean ( to 4 hr). It is arguably an extremely crude parameterization of boundary layer control on atmospheric convection. We contrast a suite of 5‐year‐long simulations with two different for land and ocean to having one globally.

Bloch-McConnell Relaxation Dispersion (BMRD) Nuclear Magnetic Resonance (NMR) spectroscopy is a key technique for studying these dynamic processes. While BMRD experiments are routinely used to probe protein motions in solution, the experiment is more demanding in the solid state, where dipolar couplings complicate the spin dynamics. It is believed that high deuteration levels are required and sufficient to obtain accurate and quantitative data. Here we show that even under fast magic-angle spinning and high levels of deuteration artifactual “bumps” in 15N R1ρ BMRD profiles are common. The origin of these artifacts is identified as a second-order three-spin Mixed Rotational and Rotary Resonance (MIRROR) recoupling condition. These artifacts are found to be a significant confounding factor for the accurate quantification of microsecond protein dynamics using BMRD in the solid state. We show that the application of low-power continuous wave (CW) decoupling simultaneously with the 15N spin-lock leads to the suppression of these conditions and enables quantitative measurements of microsecond exchange in the solid state. Remarkably, the application of decoupling allows the measurement of accurate BMRD even in fully protonated proteins at 100 kHz MAS, thus extending the scope of μs dynamics measurements in MAS NMR."}],"department":[{"_id":"PaSc"},{"_id":"NMR"}],"external_id":{"pmid":["40748291"],"isi":["001542746200001"]},"publication_status":"published","intvolume":" 147","publication":"Journal of the American Chemical Society","file":[{"relation":"main_file","checksum":"b350d56ddddefea96cebd62c277c0ff5","file_id":"20337","success":1,"content_type":"application/pdf","date_created":"2025-09-10T07:53:10Z","creator":"dernst","file_name":"2025_JACS_Tatman.pdf","date_updated":"2025-09-10T07:53:10Z","file_size":5235353,"access_level":"open_access"}],"file_date_updated":"2025-09-10T07:53:10Z"},{"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","year":"2025","date_created":"2025-09-10T05:38:17Z","date_published":"2025-09-01T00:00:00Z","ddc":["510"],"date_updated":"2026-04-07T12:32:19Z","volume":406,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"publication_status":"published","department":[{"_id":"LaEr"}],"external_id":{"isi":["001565019000005"],"arxiv":["2410.06813"]},"abstract":[{"text":"For correlated real symmetric or complex Hermitian random matrices, we prove that the local eigenvalue statistics at any cusp singularity are universal. Since the density of states typically exhibits only square root edge or cubic root cusp singularities, our result completes the proof of the Wigner–Dyson–Mehta universality conjecture in all spectral regimes for a very general class of random matrices. Previously only the bulk and the edge universality were established in this generality (Alt et al. in Ann Probab 48(2):963–1001, 2020), while cusp universality was proven only for Wigner-type matrices with independent entries (Cipolloni et al. in Pure Appl Anal 1:615–707, 2019; Erdős et al. in Commun. Math. Phys. 378:1203–1278, 2018). As our main technical input, we prove an optimal local law at the cusp using the Zigzag strategy, a recursive tandem of the characteristic flow method and a Green function comparison argument. Moreover, our proof of the optimal local law holds uniformly in the spectrum, thus we also provide a significantly simplified alternative proof of the local eigenvalue universality in the previously studied bulk (Erdős et al. in Forum Math.

The oscillations are current-voltage dual to those ordinarily observed in single junctions. The current-voltage dual circuit quantitatively accounts for temporal dynamics of the array, including the dependence on biasing conditions. Injection locking of the oscillations results in well-developed current plateaux. A thermal model explains the self-consistent reduction of the superconducting gap due to overheating of the array in the high-current state. Our work suggests that overheating determines the switching from the high-current state to the low-current state."}],"ec_funded":1,"doi":"10.1103/qvls-7s3q","date_published":"2025-07-17T00:00:00Z","ddc":["530"],"project":[{"grant_number":"P33692","_id":"0aa3608a-070f-11eb-9043-e9cd8a2bd931","name":"Cavity electromechanics across a quantum phase transition"},{"_id":"260C2330-B435-11E9-9278-68D0E5697425","grant_number":"754411","call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships"},{"_id":"eb9b30ac-77a9-11ec-83b8-871f581d53d2","name":"Protected states of quantum matter"}],"date_updated":"2026-06-03T07:16:04Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"volume":24,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2025","date_created":"2025-09-10T05:41:30Z"},{"quality_controlled":"1","month":"09","publisher":"Wiley","publication_identifier":{"eissn":["1365-294X"],"issn":["0962-1083"]},"article_number":"e70051","type":"journal_article","day":"02","status":"public","OA_place":"publisher","language":[{"iso":"eng"}],"oa":1,"author":[{"first_name":"Thomas","last_name":"Ellis","full_name":"Ellis, Thomas","orcid":"0000-0002-8511-0254","id":"3153D6D4-F248-11E8-B48F-1D18A9856A87"},{"first_name":"David","last_name":"Field","orcid":"0000-0002-4014-8478","full_name":"Field, David","id":"419049E2-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Nicholas H","orcid":"0000-0002-8548-5240","full_name":"Barton, Nicholas H","last_name":"Barton","id":"4880FE40-F248-11E8-B48F-1D18A9856A87"}],"article_type":"original","article_processing_charge":"Yes (via OA deal)","_id":"20325","issue":"15","corr_author":"1","acknowledgement":"We thank a large number of field volunteers for maintaining the population sampling, and Tom White for assistance with seed collection.

Inference can be improved by including information about parentage shared between siblings, or by modelling phenotypes or population data related to mating. However, we currently lack a framework to infer parent–offspring relationships, sibships and population parameters in a single analysis. To address this, we here extend a previous method, Fractional Analysis of Paternity and Sibships, to include population data for the case where one parent is known. We illustrate this with the example of pollen dispersal in a natural hybrid zone population of the snapdragon Antirrhinum majus. Pollen dispersal is leptokurtic, with half of mating events occurring within 30 m, but with a long tail of mating events up to 859 m. Using simulations, we find that both sibship and population information substantially improve pedigree reconstruction, and that we can expect to resolve median dispersal distances with high accuracy.","lang":"eng"}],"doi":"10.1111/mec.70051","publication_status":"published","external_id":{"isi":["001542913000001"],"pmid":["40751392"]},"department":[{"_id":"NiBa"}],"intvolume":" 34","publication":"Molecular Ecology","file":[{"date_created":"2025-12-30T10:12:17Z","success":1,"content_type":"application/pdf","checksum":"5059ad4d74e6327b84b5282a39d36774","file_id":"20911","relation":"main_file","access_level":"open_access","file_size":1698605,"file_name":"2025_MolecularEcology_Ellis.pdf","date_updated":"2025-12-30T10:12:17Z","creator":"dernst"}],"file_date_updated":"2025-12-30T10:12:17Z"},{"citation":{"mla":"Desaules, Jean-Yves Marc, et al. “Mass-Assisted Local Deconfinement in a Confined Z2 Lattice Gauge Theory.” Physical Review B, vol. 112, no. 1, 014301, American Physical Society, 2025, doi:10.1103/mfg2-t6gb.","chicago":"Desaules, Jean-Yves Marc, Thomas Iadecola, and Jad C.

As such, a theoretical understanding of the effect of confinement on LGT dynamics is not only of fundamental importance but also can lend itself to upcoming experiments. Here we show how confinement in a Z2 LGT can be avoided by proximity to a resonance between the fermion mass and the electric field strength. Furthermore, we show that this local deconfinement can become global for certain initial conditions, where information transport occurs over the entire chain. In addition, we show how this can lead to strong quantum many-body scarring starting in different initial states. Our findings provide deeper insights into the nature of confinement in Z2 LGTs and can be tested on current and near-term quantum devices."}],"doi":"10.1103/mfg2-t6gb","publication_status":"published","external_id":{"arxiv":["2404.11645"],"isi":["001530465500007"]},"department":[{"_id":"MaSe"}],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"volume":112,"date_updated":"2025-09-30T14:34:43Z","ddc":["530"],"project":[{"call_identifier":"H2020","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","grant_number":"101034413","name":"IST-BRIDGE: International postdoctoral program"}],"date_published":"2025-07-01T00:00:00Z","year":"2025","date_created":"2025-09-10T05:44:47Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345"}]
