Compressed sensing (CS)\r\napproaches have reduced scan durations by undersampling k-space and reconstructing images from partial data, and recent studies show that jointly optimizing the undersampling\r\npatterns with the reconstruction network can substantially improve performance. Still,\r\nmost current T1 mapping pipelines rely on static, hand-crafted masks that do not exploit\r\nthe full acceleration and accuracy potential. Furthermore, most existing methods do not\r\nlevarage the physical T1 decay model in optimization. In this work, we introduce T1-\r\nPILOT: an end-to-end method that explicitly incorporates the T1 signal relaxation model\r\ninto the sampling–reconstruction framework to guide the learning of non-Cartesian trajectories, cross-frame alignment, and T1 decay estimation. Through extensive experiments\r\non the CMRxRecon dataset, T1-PILOT significantly outperforms several baseline strategies (including learned single-mask and fixed radial or golden-angle sampling schemes),\r\nachieving higher T1 map fidelity at greater acceleration factors. In particular, we observe consistent gains in PSNR and VIF relative to existing methods, along with marked\r\nimprovements in delineating finer myocardial structures. Our results highlight that optimizing sampling trajectories in tandem with the physical relaxation model leads to both\r\nenhanced quantitative accuracy and reduced acquisition times.

Concrete definitions of the One Health framework, however, remain heterogeneous, leading to conceptual problems and uncertainties in the application of the framework. This article discusses several approaches to the One Health concept, and their associated consequences, with special focus on animal experimentation. The first issue addressed is how One Health should be defined, as well as what (and who) should be considered within a One Health approach. In order to shed further light on this, we explore the history of animals in biomedical science, highlighting historical milestones in the use of animal models, as well as the development and current state of ethical considerations in the field of animal experimentation. The second issue comes with the inclusion of animal experimentation per se as part of the One Health concept. Therefore, particular attention is paid to bioethical principles and the resulting problems that can arise when applying them to the One Health concept. Arguments such as the idea of inequality between humans and non-human animals, and the premise that all actions are done for the benefit of humans, are raised and then used to explore the question of whether the One Health concept is compatible with existing bioethical principles. Based on the bioethical principles of protecting the environment, the biodiversity and biosphere, this paper seeks an inclusive perspective of the One Health concept. Successful solutions will be based on this concept, which embraces all living beings. The authors conclude that a multispecies ethics approach could help create a more ethical ecosystem that is aligned with the wellbeing of all life on a shared planet."}],"doi":"10.1177/02611929261453330","author":[{"first_name":"Yesim Isil","last_name":"Ulman","full_name":"Ulman, Yesim Isil"},{"full_name":"Kostomitsopoulos, Nikos","last_name":"Kostomitsopoulos","first_name":"Nikos"},{"first_name":"Samuel","full_name":"Camenzind, Samuel","last_name":"Camenzind"},{"last_name":"Kitsara","full_name":"Kitsara, Maria","first_name":"Maria"},{"full_name":"Pavone, Ilja Richard","last_name":"Pavone","first_name":"Ilja Richard"},{"last_name":"Schober","full_name":"Schober, Sophie","id":"80b0a0ef-4b9f-11ec-b119-8d9d94c4a1d8","first_name":"Sophie"}],"OA_type":"closed access","title":"Emerging bioethical conflicts: One Health and animal experimentation","scopus_import":"1","department":[{"_id":"PreCl"}],"citation":{"chicago":"Ulman, Yesim Isil, Nikos Kostomitsopoulos, Samuel Camenzind, Maria Kitsara, Ilja Richard Pavone, and Sophie Schober. “Emerging Bioethical Conflicts: One Health and Animal Experimentation.” <i>Alternatives to Laboratory Animals</i>.

So far, the most direct evidence for BH*s\r\ncomes from a handful of sources where the host galaxy is completely outshone as suggested by their\r\nremarkably steep Balmer breaks. Here we present a novel scheme to disentangle BH*s from their\r\nhost galaxies assuming that the [O III]5008˚A line arises exclusively from the host. Using a sample\r\nof 98 LRDs (z ≈ 2 − 9) with high quality NIRSpec/PRISM spectra, we demonstrate that the hostsubtracted median stack displays a Balmer break > 2× stronger than massive quiescent galaxies,\r\nwith the rest-optical continuum resembling a blackbody-like SED (Teff ≈ 4050 K, log(Lbol) ≈ 43.9\r\nerg s−1\r\n, Reff ≈ 1300 au). We measure a steep Balmer decrement (Hα/Hβ > 10) and numerous\r\ndensity-sensitive features (e.g., Fe II, He I, O I). These are hallmark signatures of dense gas envelopes,\r\nproviding population-level evidence that BH*s indeed power LRDs. In the median LRD, BH*s account\r\nfor ∼ 20% of the UV emission, ∼ 50% at the Balmer break, and ∼ 90% at wavelengths longer\r\nthan Hα with the remainder arising from the host. BH*s preferentially reside in low-mass galaxies\r\n(M⋆ ≈ 108 M⊙) undergoing recent starbursts, as evidenced by extreme emission line EWs (e.g.,\r\n[O III]5008˚A≈ 1100˚A, C III]≈ 12˚A), thereby favoring BH* origins linked to star-formation. We show\r\nV-shaped LRD selections are biased to high BH*/host fractions (≳ 60% at 5500˚A) – less dominant\r\nBH*s may be powering JWST’s blue broad-line AGN.

Genome sequencing and bioinformatics analyses revealed biosynthetic gene clusters (BGCs) that may specify production of chemically diverse secondary metabolites. Various culture conditions were employed to induce metabolite production, and subsequent LC-MS analyses facilitated the identification of the produced compounds and their correlation with the corresponding BGCs. These analyses of sediment-derived Streptomyces spp. highlight their extensive biosynthetic potential, revealing a diverse range of bioactive secondary metabolites, including siderophores, antibiotics, and other compounds with potential therapeutic applications. Genomes of two Streptomyces isolates, one of them representing a potentially new species, harbored several uncharacterized BGCs that may specify biosynthesis of novel secondary metabolites. Although targeted overexpression of pathway-specific regulators from these BGCs did not yield additional metabolites, whereas knockout experiments led to metabolic changes, presumably reflecting regulatory or compensatory interactions between multiple biosynthetic pathways. Continued exploration of these strains and their BGCs may lead to the discovery of new bioactive molecules with pharmaceutical and biotechnological applications.","lang":"eng"}],"publication":"Frontiers in Microbiology","publication_status":"published","title":"Unveiling the genomes and secondary metabolomes of Streptomyces spp. from freshwater sediments","volume":17,"PlanS_conform":"1","status":"public","month":"04","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"has_accepted_license":"1","ddc":["572"],"year":"2026","date_updated":"2026-06-10T07:49:04Z","language":[{"iso":"eng"}],"quality_controlled":"1","_id":"21953","date_published":"2026-04-20T00:00:00Z"},{"publisher":"Springer Nature","article_type":"original","date_created":"2026-06-08T08:34:43Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"Published Version","publication_identifier":{"issn":["0924-9907"],"eissn":["1573-7683"]},"doi":"10.1007/s10851-026-01300-1","abstract":[{"lang":"eng","text":"We investigate a framework for train-free MRI segmentation based on Topological Data Analysis.

A key ingredient is the extraction of approximate representative cycles from persistence diagrams, which provides an interpretable link between persistent features and anatomical components. To clarify the method’s scope, we make the underlying topological and intensity assumptions explicit, quantify when they hold on real data, and analyze typical failure modes. We evaluate the approach on glioblastoma and on fetal cortical plate segmentation, with comparisons to unsupervised and deep-learning references.

Their activation by fasting is key for survival and is thought to be triggered by feedback when energy stores are low. However, we know that environmental cues can also regulate AgRP neurons since cues that predict future food intake rapidly inhibit AgRP neurons, but is the converse true: can the prediction of future fasting rapidly activate AgRP neurons? Here, we show in mice that such rapid fasting activation of AgRP neurons does occur. This rapid activation is driven by excitatory input from paraventricular hypothalamic (PVH) neurons expressing Sim2, which are bidirectionally sensitive to predictions of future energy state.

In the first part, we present a hybrid symbolic-numeric algorithm for certifying the feasibility of weakly feasible, degenerate SDPs. By reformulating linear matrix inequalities (LMIs) into a structured polynomial system via facial reduction and incidence varieties, we guarantee the existence of an isolated exact solution. This algebraic reduction enables the certification of maximum-rank numerical approximations using methods from algebraic geometry.\r\n\r\nIn the second part, we address the severe ill-conditioning and loss of quadratic convergence that plague standard path-tracking methods near isolated singular roots. To overcome this, we propose tracking algorithms that achieve superlinear convergence without the computational bloat characteristic of classical deflation techniques. By modeling the solution path as a generalized fractional Puiseux series, our approach combines an explicitly derived algebraic predictor with a localized hyperplane desingularization phase during the corrector step. Furthermore, we introduce a continuous path-limit method and an extension of the geometric sequence rule to directly extract exact fractional exponents. This bypasses traditional heuristic trial-and-error methods and explicitly accommodates sparse series expansions. Numerical experiments confirm that our method significantly reduces the cumulative number of matrix inversions while achieving high-accuracy root approximations, even for heavily degenerate systems exhibiting higher coranks.","lang":"eng"}],"doi":"10.15479/AT-ISTA-21957","degree_awarded":"PhD","oa_version":"Published Version","publication_identifier":{"issn":["2663-337X"],"isbn":["978-3-99078-079-4"]}},{"department":[{"_id":"GradSch"},{"_id":"MaSe"}],"project":[{"call_identifier":"H2020","name":"IST-BRIDGE: International postdoctoral program","grant_number":"101034413","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c"}],"ec_funded":1,"title":"Research Data: \"Quasi-solitons in Rydberg atom chains\"","author":[{"last_name":"Kerschbaumer","full_name":"Kerschbaumer, Aron","id":"ade85a9c-3200-11ee-973b-91c1eb240410","orcid":"0009-0002-2370-8661","first_name":"Aron"}],"OA_place":"repository","file_date_updated":"2026-06-15T22:02:07Z","day":"16","status":"public","oa":1,"article_processing_charge":"No","type":"research_data","citation":{"ieee":"A.

We model the possibility that the diversity-promoting effects of balancing selection extend to other loci that show sign epistasis with a locus under balancing selection. Rather than focusing on overdominance, as was done in previous efforts, we explore the effects of negative frequency dependence and show that this has important effects on the conditions under which the diversity-promoting effect of epistasis can occur in diploids. Our results show that not only recombination rate but also the dominance of sign epistasis are key parameters that determine the maintenance of polymorphism beyond the locus under direct balancing selection. We suggest that the effect we explore may play a significant role, especially when balancing selection acts on major effect loci."}],"related_material":{"record":[{"status":"public","relation":"dissertation_contains","id":"21918"}]},"date_created":"2026-06-09T12:26:11Z","tmp":{"name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","short":"CC BY-NC (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode","image":"/images/cc_by_nc.png"},"month":"04","year":"2026","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","oa":1,"type":"preprint","article_processing_charge":"No","citation":{"short":"K.

The standard computational framework combines density functional theory (DFT) with nonequilibrium Green’s functions (NEGF) using low-rung exchange-correlation functionals such as PBE, which overestimate the conductances. More advanced correction methods exist but require complex workflows and high computational cost, limiting their accessibility. Here, we introduce a physically motivated approach that approximates results obtained with high-rung functionals. Our method fits the PBE-calculated transmission to a Breit-Wigner form and subsequently refines the fit parameters using molecular orbital energies and metal densities of states computed for the isolated subsystems with high-rung functionals. This approach is applicable to a broad range of molecular junctions yielding conductance values in quantitative agreement with experiments. Our approach is simple, low-cost, and accurate, making it well-suited for routine and large-scale prediction of single-molecule junction conductance.","lang":"eng"}],"publication":"Nano Letters","publication_status":"published","doi":"10.1021/acs.nanolett.6c01462","date_created":"2026-06-10T07:27:19Z","publisher":"American Chemical Society","article_type":"letter_note","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ieee":"A.

In this paper, we focus on complete bipartite graphs. First, we completely resolve the problem when H is the family of all spanning complete bipartite graphs on n vertices. We then focus on its subfamilies, that is, {Kt,n-t : t E T} for a fixed set of integers T c [[n/2]]. We prove that the odd-Ramsey problem is equivalent to determining the maximum dimension of a linear binary code avoiding codewords of given weights, and leverage known results from coding theory to deduce asymptotically tight bounds in our setting.

Here, we present a time-resolved optical polarimetry technique that allows us to detect and\r\ncharacterize such low-frequency modes, and use it to observe the Goldstone mode in the multi-Q broken helix\r\nphase of EuIn2As2. The strength of our technique comes from the ability to distinguish between nematic and\r\nmagnetization dynamics in order to yield information about the mode structure, in addition to its frequency. We\r\nfind that the nearly uniform spin precession characteristic of a Goldstone mode is realized only when a small\r\nmagnetic field is used to unpin the broken helix from local strain generated during crystal growth. In this regime,\r\nthe mode frequency scales linearly with the applied field due to the ground state C2z symmetry of the broken\r\nhelix. Our work shows how optical polarimetry can be used to study the Goldstone modes of complex magnets."}],"publication":"Physical Review B","researchdata_availability":"yes","publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"oa_version":"None","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"American Physical Society","article_type":"original","date_created":"2026-06-22T08:52:01Z","day":"01","intvolume":"       113","das_tickbox":"1","article_processing_charge":"No","type":"journal_article","citation":{"chicago":"Liebman-Peláez, A., S.
