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."}],"date_updated":"2026-06-10T07:49:04Z","publication_identifier":{"issn":["1664-302X"]},"has_accepted_license":"1","DOAJ_listed":"1","title":"Unveiling the genomes and secondary metabolomes of Streptomyces spp. from freshwater sediments","ddc":["572"],"OA_place":"publisher","OA_type":"gold","type":"journal_article","publication":"Frontiers in Microbiology","date_published":"2026-04-20T00:00:00Z"},{"department":[{"_id":"UlWa"}],"tmp":{"image":"/images/cc_by.png","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)"},"article_number":"20","article_type":"original","year":"2026","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","PlanS_conform":"1","issue":"3","month":"05","external_id":{"arxiv":["2401.01160"]},"author":[{"first_name":"Anton","full_name":"François, Anton","last_name":"François"},{"full_name":"Tinarrage, Raphaël","id":"40ebcc9d-905f-11ef-bf0a-dc475da8a04e","first_name":"Raphaël","orcid":"0000-0002-1404-1095","last_name":"Tinarrage"}],"arxiv":1,"intvolume":"        68","publication_status":"published","file":[{"content_type":"application/pdf","date_updated":"2026-06-10T07:58:58Z","file_name":"2026_JourMathImaging_Francois.pdf","checksum":"34080653e0f9c6160856a6bbca9b5248","date_created":"2026-06-10T07:58:58Z","success":1,"file_size":6070434,"relation":"main_file","access_level":"open_access","file_id":"21990","creator":"dernst"}],"oa_version":"Published Version","type":"journal_article","scopus_import":"1","publication":"Journal of Mathematical Imaging and Vision","date_published":"2026-05-25T00:00:00Z","has_accepted_license":"1","title":"Train-free segmentation in MRI with cubical persistent homology","ddc":["510"],"OA_place":"publisher","OA_type":"hybrid","language":[{"iso":"eng"}],"volume":68,"file_date_updated":"2026-06-10T07:58:58Z","citation":{"ama":"François A, Tinarrage R.

The pipeline proceeds in three steps, first identifying the whole object to segment via automatic thresholding, then detecting a distinctive subset whose topology is known in advance, and finally deducing the various components of the segmentation. 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. By operating without large annotated datasets, the method is well suited to scarce-data settings and provides an interpretable baseline and practical initialization for expert refinement or learning-based pipelines."}],"date_updated":"2026-06-10T08:00:52Z","publication_identifier":{"eissn":["1573-7683"],"issn":["0924-9907"]},"corr_author":"1","date_created":"2026-06-08T08:34:43Z","oa":1,"day":"25","publisher":"Springer Nature","_id":"21954","status":"public","acknowledgement":"Open access funding provided by Institute of Science and Technology (IST Austria).","article_processing_charge":"Yes (via OA deal)"},{"department":[{"_id":"AmDo"}],"pmid":1,"article_type":"original","quality_controlled":"1","year":"2026","keyword":["hunger","hypothalamus","AGRP neurons","neuroscience","metabolism","homeostasis","feeding","food intake","energy balance","appetite"],"month":"06","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"last_name":"Walker","first_name":"Samuel J.","full_name":"Walker, Samuel J."},{"full_name":"Lowenstein, Elijah D.","first_name":"Elijah D.","last_name":"Lowenstein"},{"last_name":"Douglass","orcid":"0000-0001-5398-6473","first_name":"Amelia May Barnett","id":"de5f6fda-80fb-11ef-996f-a8c4ecd8e289","full_name":"Douglass, Amelia May Barnett"},{"full_name":"Thomas, Callum M.P.","first_name":"Callum M.P.","last_name":"Thomas"},{"last_name":"Madara","first_name":"Joseph C.","full_name":"Madara, Joseph C."},{"first_name":"Hakan","full_name":"Kucukdereli, Hakan","last_name":"Kucukdereli"},{"last_name":"Barbosa-Meillon","full_name":"Barbosa-Meillon, Eunice A.","first_name":"Eunice A."},{"last_name":"Tao","full_name":"Tao, Jenkang","first_name":"Jenkang"},{"last_name":"Resch","full_name":"Resch, Jon M.","first_name":"Jon M."},{"last_name":"Lowell","full_name":"Lowell, Bradford B.","first_name":"Bradford B."}],"main_file_link":[{"url":"https://doi.org/10.1101/2025.09.27.678865","open_access":"1"}],"external_id":{"pmid":["42235510"]},"publication_status":"inpress","oa_version":"Preprint","scopus_import":"1","type":"journal_article","date_published":"2026-06-03T00:00:00Z","publication":"Neuron","OA_place":"repository","title":"A hypothalamic circuit for anticipating future changes in energy balance","OA_type":"green","doi":"10.1016/j.neuron.2026.05.010","citation":{"chicago":"Walker, Samuel J., Elijah D.

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. Thus, cognitively processed contextual information conveyed by PVHSim2 neurons strongly activates AgRP neurons. Lastly, chronic silencing of PVHSim2 neurons causes persistent hypophagia. This PVHSim2-to-AgRP-neuron circuit, by anticipating and preventing negative energy balance, provides an important new dimension of hunger regulation.","lang":"eng"}],"_id":"21955","day":"03","publisher":"Elsevier","oa":1,"date_created":"2026-06-08T09:24:25Z","article_processing_charge":"No","acknowledgement":"We thank all members of the B.B.L. laboratory for helpful discussions.

Corticogenesis is however susceptible to genetic interference of critical signaling pathways, including mutations in Mtor/Rptor that lead to microcephaly. How the loss of Rptor/mTORC1 function affects cortical developmental programs, at single cell level, is still unknown. Here, we utilized Mosaic Analysis with Double Markers (MADM) technology to probe Rptor gene function upon sparse single cell- or global tissue-wide ablation. We found that tissue-wide effects drive the etiology of cortical microcephaly upon loss of Rptor, rather than deficits in projection neuron genesis. Conversely, Rptor function is cell-autonomously required for postnatal projection neuron survival in a highly cell-type-specific manner. Collectively, our results suggest that the fine balance of precise cell-type-specific cell-autonomous Rptor/mTORC1 function in concert with non-cell-autonomous tissue-wide effects is essential for the development of a properly-sized cerebral cortex with accurate projection neuron diversity.","lang":"eng"}],"date_updated":"2026-06-16T08:45:25Z"},{"department":[{"_id":"SiHi"},{"_id":"PreCl"},{"_id":"GradSch"}],"acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"},{"_id":"PreCl"}],"tmp":{"short":"CC BY-NC (4.0)","name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","image":"/images/cc_by_nc.png","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode"},"year":"2026","month":"05","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"last_name":"Miranda","orcid":"0000-0001-6618-6889","full_name":"Miranda, Osvaldo","id":"862A3C56-A8BF-11E9-B4FA-D9E3E5697425","first_name":"Osvaldo"},{"first_name":"Ximena","id":"475990FE-F248-11E8-B48F-1D18A9856A87","full_name":"Contreras, Ximena","last_name":"Contreras"},{"last_name":"Pauler","orcid":"0000-0002-7462-0048","full_name":"Pauler, Florian","id":"48EA0138-F248-11E8-B48F-1D18A9856A87","first_name":"Florian"},{"id":"70ADC922-B424-11E9-99E3-BA18E6697425","first_name":"Amarbayasgalan","full_name":"Davaatseren, Amarbayasgalan","last_name":"Davaatseren"},{"full_name":"Amberg, Nicole","id":"4CD6AAC6-F248-11E8-B48F-1D18A9856A87","first_name":"Nicole","last_name":"Amberg","orcid":"0000-0002-3183-8207"},{"full_name":"Streicher, Carmen","id":"36BCB99C-F248-11E8-B48F-1D18A9856A87","first_name":"Carmen","last_name":"Streicher"},{"last_name":"Villalba Requena","orcid":"0000-0002-5615-5277","full_name":"Villalba Requena, Ana","id":"68cb85a0-39f7-11eb-9559-9aaab4f6a247","first_name":"Ana"},{"last_name":"Heger","full_name":"Heger, Anna-Magdalena","first_name":"Anna-Magdalena","id":"4B76FFD2-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Marie, Corentine","first_name":"Corentine","last_name":"Marie"},{"full_name":"Hassan, Bassem A.","first_name":"Bassem A.","last_name":"Hassan"},{"last_name":"Rülicke","first_name":"Thomas","full_name":"Rülicke, Thomas"},{"id":"37B36620-F248-11E8-B48F-1D18A9856A87","first_name":"Simon","full_name":"Hippenmeyer, Simon","last_name":"Hippenmeyer","orcid":"0000-0003-2279-1061"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.64898/2026.05.01.722191"}],"project":[{"name":"Stem Cell Modulation in Neural Development and Regeneration/ P05-Molecular Mechanisms of Neural Stem Cell Lineage Progression","_id":"059F6AB4-7A3F-11EA-A408-12923DDC885E","grant_number":"F7805"},{"grant_number":"725780","call_identifier":"H2020","name":"Principles of Neural Stem Cell Lineage Progression in Cerebral Cortex Development","_id":"260018B0-B435-11E9-9278-68D0E5697425"}],"publication_status":"submitted","oa_version":"Preprint","type":"preprint","date_published":"2026-05-05T00:00:00Z","publication":"bioRxiv","ec_funded":1,"ddc":["570"],"OA_place":"repository","title":"Pten orchestrates neurogenic radial glia lineage progression and tunes neocortical astrocyte production","has_accepted_license":"1","OA_type":"green","citation":{"chicago":"Miranda, Osvaldo, Ximena Contreras, Florian Pauler, Amarbayasgalan Davaatseren, Nicole Amberg, Carmen Streicher, Ana Villalba Requena, et al. “Pten Orchestrates Neurogenic Radial Glia Lineage Progression and Tunes Neocortical Astrocyte Production.” <i>BioRxiv</i>, n.d. <a href=\"https://doi.org/10.64898/2026.05.01.722191\">https://doi.org/10.64898/2026.05.01.722191</a>.","apa":"Miranda, O., Contreras, X., Pauler, F., Davaatseren, A., Amberg, N., Streicher, C., … Hippenmeyer, S.

How RGPs generate appropriate quantities of distinct cortical cell-types to safeguard a brain of correct size, is not well understood. However, genetic aberration in human, including mutations in PTEN, lead to cortical malformation such as macrocephaly, albeit with unknown etiology. Here we utilized Mosaic Analysis with Double Markers (MADM)-based clonal analysis and single cell phenotyping to decipher the role of Pten in neurogenic and gliogenic RGP lineage progression during cortical ontogeny. While neurogenic RGP lineage progression and projection neuron production was moderately altered in the absence of Pten, cortical astrocyte production was drastically increased. Through genetic epistasis experiments we show that the loss of Pten uncouples astrocyte generation from essential growth factor signaling hubs, funneling into MAPK. Collectively, our results suggest that Pten regulates RGP lineage progression with distinct sequential functions in cortical projection neurogenesis and astrocyte production to ensure the emergence of a correctly-sized cerebral cortex.","lang":"eng"}],"date_updated":"2026-06-16T08:57:20Z","day":"05","_id":"21963","corr_author":"1","oa":1,"date_created":"2026-06-09T08:08:53Z","status":"public","acknowledgement":"We thank Kay-Uwe Wagner (Wayne State University) for generously sharing Jak1/2–flox mouse lines; A.\r\nSommer (VBCF GmbH, NGS Unit) for technical support; N.

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.

For example, if A is finite with n=#A, and the coloring is random, then the chromatic Delaunay mosaic has O(n⌈d/2⌉) cells in expectation. In contrast, for Delone sets and Poisson point processes in Rd, the expected number of cells within a closed ball is only a constant times the number of points in this ball.

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.

This opacity creates challenges for trust, accountability, and compliance with\r\nemerging regulatory expectations such as the “right to an explanation”. While traditional explainability methods—feature attributions, counterfactuals, surrogate models—and interpretable model classes provide valuable insights for engineers, they often fall short of delivering the contextual, conversational explanations that\r\nreal users expect. Large Language Models (LLMs) offer a promising new avenue for explanation due to their\r\nability to engage interactively, adapt to user needs, and translate technical outputs into more accessible reasoning. However, their tendencies toward hallucination, conflict avoidance, and oversimplification introduce\r\nserious risks when used as explanatory agents. This paper analyzes these opportunities and limitations, examines verification strategies for ensuring explanation fidelity, and situates LLM-generated explanations within\r\nbroader concerns about public trust. The paper concludes by outlining best practices and future research directions for building robust, verifiable, and human-aligned explanation systems."}],"date_updated":"2026-06-24T08:37:00Z","day":"01","publisher":"Science and Technology Publications","_id":"22103","corr_author":"1","oa":1,"date_created":"2026-06-21T22:03:00Z","acknowledgement":"This work has been supported by the European Research Council under Grant No.: ERC-2020-AdG\r\n101020093.

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.","lang":"eng"}],"date_updated":"2026-06-24T09:49:27Z","quality_controlled":"1","year":"2026","month":"06","extern":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","issue":"22","dataavailabilitystatement":"The data that support the findings of this article are openly\r\navailable [27 -  https://doi.org/10.7910/dvn/rqp3az], embargo periods may apply.","article_type":"original","article_number":"224401","publication_status":"published","supplementarymaterial":"no","oa_version":"None","author":[{"full_name":"Liebman-Peláez, A.","first_name":"A.","last_name":"Liebman-Peláez"},{"last_name":"Garratt","first_name":"S.

Their potential to generate large spin polarization without spin-orbit coupling has created strong interest in probes that access the underlying order parameter directly. In this Perspective, we show that linear magneto-birefringence (LMB) provides a natural and broadly applicable route to detecting altermagnetic order. Building on the correspondence between the momentum-space structure of NRSS and the ferroic ordering of magnetic multipoles in real space, we demonstrate how $d$-wave and $g$-wave NRSS textures yield distinct LMB responses. We present a symmetry-based framework that identifies the optical geometries and field configurations required to isolate specific multipole components, enabling domain imaging and providing benchmarks for theoretical models of LMB.","lang":"eng"}],"publication_identifier":{"eissn":["2397-4648"]},"language":[{"iso":"eng"}],"doi":"10.1038/s41535-026-00901-8","citation":{"mla":"Sunko, Veronika, and J.

Although correlated noise, in particular via matrix factorizations, has been shown to improve accuracy, prior theoretical work focused primarily on the prefix-sum workload. That workload assumes a constant learning rate, whereas in practice learning rate schedules are widely used to accelerate training and improve convergence. We close this gap by deriving general upper and lower bounds for a broad class of learning rate schedules in both single- and multi-epoch settings. Building on these results, we propose a learning-rate-aware factorization that achieves improvements over prefix-sum factorizations under both MaxSE and MeanSE error metrics. Our theoretical analysis yields memory-efficient constructions suitable for practical deployment, and experiments on CIFAR-10 and IMDB datasets confirm that schedule-aware factorizations improve accuracy in private training.","lang":"eng"}],"publication_identifier":{"eissn":["1868-8969"],"isbn":["9783959774192"]},"title":"Learning rate scheduling with matrix factorization for private training","has_accepted_license":"1","OA_place":"publisher","ddc":["000"],"OA_type":"gold","type":"conference","researchdata_availability":"no","scopus_import":"1","ec_funded":1,"publication":"7th Symposium on Foundations of Responsible Computing","das_tickbox":"0","date_published":"2026-06-01T00:00:00Z"},{"ddc":["530"],"OA_place":"publisher","has_accepted_license":"1","title":"On-chip tuning of superconductivity in fullerides via current-driven Rb+ intercalation","OA_type":"hybrid","researchdata_availability":"no","scopus_import":"1","type":"journal_article","date_published":"2026-06-23T00:00:00Z","das_tickbox":"0","publication":"ACS Nano","publisher":"American Chemical Society","day":"23","_id":"22145","date_created":"2026-06-28T22:01:34Z","oa":1,"acknowledgement":"A.G. and K.P.S. acknowledge the DFG through CRC 1238 (277146847, A01) and DFG project SE 2575.

We apply this method to synthesize fulleride superconductors via Rb+ intercalation into a C60 film. During the intercalation, we monitor the stoichiometry via UHV-Raman spectroscopy and probe superconductivity via transport measurements. An increase of the superconducting transition temperature from 7.0 K to 14.5 K is observed when the stoichiometry is tuned from Rb2.7C60 to Rb3C60. In our experiment, an ionic Rb+ flux into the host material is induced by an applied electronic current via a Butler–Volmer-type mechanism. Electro-intercalation captivates through improved stoichiometric precision, the ability to smoothly vary stoichiometry via duration of current application, and the absence of a lower limit of the volume of the host material. It represents a powerful concept for the on-chip synthesis of intercalated materials, battery research, and beyond.","lang":"eng"}],"date_updated":"2026-06-29T09:00:33Z","quality_controlled":"1","year":"2026","keyword":["fulleride","intercalation","alkali metal","superconductivity","Raman"],"month":"06","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","issue":"24","PlanS_conform":"1","department":[{"_id":"MiLe"}],"article_type":"original","pmid":1,"tmp":{"image":"/images/cc_by.png","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)"},"publication_status":"published","page":"17360-17372","supplementarymaterial":"yes","oa_version":"Published Version","file":[{"creator":"dernst","access_level":"open_access","file_id":"22150","file_size":6290296,"relation":"main_file","success":1,"date_created":"2026-06-29T08:58:12Z","checksum":"01ec8ee6fab7bf563df7af13f6b43045","file_name":"2026_ACSNano_Shchukin.pdf","date_updated":"2026-06-29T08:58:12Z","content_type":"application/pdf"}],"author":[{"last_name":"Shchukin","full_name":"Shchukin, Konstantin P.","first_name":"Konstantin P."},{"last_name":"Gallego Lacey","first_name":"Oliver N.","full_name":"Gallego Lacey, Oliver N."},{"orcid":"0000-0001-5524-596X","last_name":"Coquinot","first_name":"Baptiste","id":"f8417bd4-f599-11ee-a482-b927e3ed1e8e","full_name":"Coquinot, Baptiste"},{"last_name":"Jakowski","full_name":"Jakowski, Jacek","first_name":"Jacek"},{"full_name":"Huang, Jingsong","first_name":"Jingsong","last_name":"Huang"},{"last_name":"Staudenmayer","full_name":"Staudenmayer, Patrik","first_name":"Patrik"},{"full_name":"Falke, Yannic","first_name":"Yannic","last_name":"Falke"},{"last_name":"Pandeya","full_name":"Pandeya, Ram Prakash","first_name":"Ram Prakash"},{"full_name":"Grüneis, Alexander","first_name":"Alexander","last_name":"Grüneis"}],"external_id":{"pmid":["42260723"]},"intvolume":"        20"},{"article_number":"jacs.6c02632","date_published":"2026-06-19T00:00:00Z","article_type":"original","pmid":1,"publication":"Journal of the American Chemical Society","type":"journal_article","month":"06","extern":"1","OA_type":"closed access","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","quality_controlled":"1","title":"Mechanical gating of redox access in molecular electrocatalysis","year":"2026","publication_identifier":{"issn":["0002-7863"],"eissn":["1520-5126"]},"abstract":[{"text":"Molecular electrocatalysis is commonly interpreted through electronic descriptors, implicitly treating catalysts as mechanically passive during redox cycling. Yet, electron transfer often imposes structural demands on molecular scaffolds, raising the question of whether internal mechanical constraints can directly regulate access to reactive states and, in turn, catalytic outcomes. Addressing this question has remained challenging because mechanical effects are typically inseparable from changes in composition or electronic structure. Here, we achieve this separation by exploiting two constitutionally identical molecular catalysts whose only distinction is ligand geometry. This minimal geometric variation enables or suppresses intramolecular hydrogen bonding, thereby encoding distinct mechanical constraints that isolate molecular mechanics as a variable in redox accessibility. In the α isomer, molecular constraints impose a mechanically enforced barrier that severely limits access to the reactive redox state. This disrupts the temporal ordering of elementary steps, and diverts reactivity toward competing hydrogen evolution, eroding both selectivity and stability. In contrast, mechanical compliance in the β isomer enables facile access to the redox-active state, allowing CO2 activation to intrinsically outpace water activation and yielding CO selectivities exceeding 92%. Operando spectroscopy and real-time mass spectrometry, combined with computational simulation, directly resolve this mechanically gated reaction sequence as it unfolds. Molecular mechanics thus emerge as determinants that link electron flow to reaction sequencing and catalytic selectivity, revealing that constitutionally similar catalysts can be mechanically, and therefore catalytically, distinct.","lang":"eng"}],"date_updated":"2026-06-29T06:39:21Z","author":[{"last_name":"Mendhe","first_name":"Rahul Mahadeo","full_name":"Mendhe, Rahul Mahadeo"},{"last_name":"Christudas Dargily","first_name":"Neethu","id":"19edef5c-384c-11ef-8188-c73c9c31d601","full_name":"Christudas Dargily, Neethu"},{"last_name":"Kottaichamy","full_name":"Kottaichamy, Alagar Raja","first_name":"Alagar Raja"},{"last_name":"Dutt","full_name":"Dutt, Shifali","first_name":"Shifali"},{"last_name":"Sk","full_name":"Sk, Mukaddar","first_name":"Mukaddar"},{"first_name":"Harish","full_name":"Makri Nimbegondi Kotresh, Harish","last_name":"Makri Nimbegondi Kotresh"},{"full_name":"Ottakam Thotiyl, Musthafa","first_name":"Musthafa","last_name":"Ottakam Thotiyl"}],"citation":{"short":"R.M.
