The extent to which humans cooperate with each other is also an essential feature that differentiates them from other animals. Cooperation occurs even in the absence of altruistic motivations, when it is selfishly incentivised by the expectation of a future reward. For example, many economic interactions are well described that way. This kind of cooperation requires that people exhibit reciprocal behaviour that acts as a mechanism that rewards cooperation.\r\nWith game-theoretic models, it is possible to formally study potential such mechanisms and under what conditions they can exist. This thesis contributes to this effort by analysing recently introduced models of cooperation that advance on previous work by taking into account the potential for pre-existing inequality among cooperating individuals as well as the different forms that reciprocity can take.\r\nIndividuals may differ both intrinsically, in their abilities, as well as extrinsically, in the amount of resources they have available. Allowing for such differences in a model of cooperation helps to understand how inequality affects the potential for, and outcomes of, cooperation among unequals. In this thesis, it is shown that in the presence of intrinsic inequality, a similar unequal distribution of resources can increase the potential for cooperation. This effect is stronger the smaller the group is in which cooperation takes place. It is also shown that under particular assumptions, if the unequal members of a group vary the size of their contributions to a cooperative effort over time, they can thereby increase their efficiency and improve the collective outcome.\r\nCooperative behaviour in a two-person interaction can be rewarded either by direct reciprocation whenever the same two people interact again, or indirectly by a third party who observed the interaction. In the latter case of indirect reciprocity, individuals are proximally rewarded by a good reputation, which ultimately translates to being rewarded with cooperative behaviour by others. This mechanism can enable selfishly motivated cooperation even in circumstances where individuals are unlikely to meet again, akin to how money facilitates trade. While these two forms of reciprocity have mostly been studied in isolation, this thesis analyses both direct and indirect reciprocity in a general model in order to compare their relative effectiveness under different circumstances. The contribution of this thesis is an extension of previous work regarding a specific kind of interaction, whose parameters allow for convenient mathematical analysis, to the most general set of possible interactions."}],"day":"25","date_published":"2025-06-25T00:00:00Z","doi":"10.15479/AT-ISTA-19903"},{"type":"dissertation","ec_funded":1,"ddc":["000","519"],"degree_awarded":"PhD","status":"public","fulldoi":"https://doi.org/10.15479/AT-ISTA-20138","doi_confirm":"1","project":[{"_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","grant_number":"863818","name":"Formal Methods for Stochastic Models: Algorithms and Applications","call_identifier":"H2020"},{"_id":"4029cfc7-b034-11f1-9e55-88ab2ff3b6ee","grant_number":"COE12","name":"Bilateral Artificial Intelligence (Chatterjee)"}],"title":"Structural properties of games on graphs","file":[{"checksum":"c6c4df9777f4537940de7ab392ad57e2","creator":"jsvoboda","file_id":"20177","file_size":5927291,"access_level":"open_access","file_name":"2025_Svoboda_Jakub_Thesis.pdf","date_created":"2025-08-14T09:54:43Z","content_type":"application/pdf","success":1,"date_updated":"2025-08-14T09:54:43Z","relation":"main_file"},{"checksum":"485e9f9822821bc03666d245d80aaa08","creator":"jsvoboda","file_size":6731815,"file_id":"20178","access_level":"closed","file_name":"2025_Svoboda_Jakub_Thesis.zip","date_created":"2025-08-14T09:55:20Z","content_type":"application/zip","relation":"source_file","date_updated":"2025-08-21T11:48:39Z"}],"publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","page":"167","language":[{"iso":"eng"}],"tmp":{"name":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode","image":"/images/cc_by_nc_sa.png","short":"CC BY-NC-SA (4.0)"},"article_processing_charge":"No","has_accepted_license":"1","file_date_updated":"2025-08-21T11:48:39Z","oa":1,"related_material":{"record":[{"status":"public","id":"12787","relation":"part_of_dissertation"},{"relation":"part_of_dissertation","status":"public","id":"12101"},{"status":"public","id":"12257","relation":"part_of_dissertation"},{"relation":"part_of_dissertation","id":"15297","status":"public"},{"id":"18703","status":"public","relation":"part_of_dissertation"}]},"OA_place":"publisher","corr_author":"1","license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","supervisor":[{"last_name":"Chatterjee","first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu"}],"date_created":"2025-08-05T14:33:59Z","year":"2025","citation":{"apa":"Svoboda, J.

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.

These estimates have profound consequences for eigenvector overlaps and thermalization problems. More concretely, we obtain, e.g., the optimal eigenstate thermalization hypothesis (ETH) uniformly in the spectrum for Wigner matrices, an optimal lower bound on non-Hermitian eigenvector overlaps, and prethermalization for deformed Wigner matrices.\tIn order to prove our novel multi-resolvent local laws, we develop and devise two main methods, the static Psi-method and the dynamical Zigzag strategy. \r\n\t\r\nIn Part II, we study Bardeen-Cooper-Schrieffer (BCS) theory, the standard mean field microscopic theory of superconductivity. We focus on asymptotic formulas for the characteristic critical temperature and energy gap of a superconductor and prove universality of their ratio in various physical regimes. Additionally, we investigate multi-band superconductors and show that inter-band coupling effects can only enhance the critical temperature. \r\n\t\r\nIn Part III, we study quantum lattice systems. On the one hand, we show a strong version of the local-perturbations-perturb-locally (LPPL) principle for the ground state of weakly interacting quantum spin systems with a uniform on-site gap. On the other hand, we introduce a notion of a local gap and rigorously justify response theory and the Kubo formula under the weakened assumption of a local gap. \r\n\t\r\nAdditionally, we discuss two classes of problems which do not fit into the three main parts of the thesis. These are deformational rigidity of Liouville metrics on the torus and relativistic toy models of particle creation via interior-boundary-conditions (IBCs).

However, its practical application is hindered by inherently high lattice thermal conductivity and low electrical conductivity. In this study, we address these challenges by surface functionalization of PbS nanocrystals using Cu2S molecular complexes-based ligand displacement. The molecular complexes facilitate the incorporation of Cu into the PbS matrix and leads to the formation of nanoscale defects, dislocations, and strain fields while optimizing the charge carrier transport. The structural modulations enhance the phonon scattering and lead to a significant reduction in lattice thermal conductivity of 0.60 W m−1K−1 at 867 K in the PbS-Cu2S system. Simultaneously, the Cu incorporation improves electrical conductivity by increasing both carrier concentration and mobility with carefully optimized the content of Cu2S molecular complexes. These synergistic modifications yield a peak figure-of-merit (zT) of 1.05 at 867 K for the PbS-1.0 %Cu2S sample, representing an almost twofold enhancement in TE performance compared to pristine PbS. This work highlights the effectiveness of surface treatment in overcoming the intrinsic limitations of PbS-based materials and presents a promising strategy for the development of high-efficiency TE systems."}],"date_published":"2025-04-01T00:00:00Z","day":"01","doi":"10.1016/j.jcis.2024.12.067","citation":{"apa":"Shu, H., Zhao, M., Lu, S., Wan, S., Genç, A., Huang, L., … Liu, Y.

Characterization techniques, including thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD), elucidated a plausible reaction pathway for the formation of phase-pure BFO NPs. Rietveld refinement of the XRD data, in conjunction with transmission electron microscopy (TEM) and Raman spectroscopy, confirmed the synthesis of single-phase BFO NPs at 400 °C, displaying a space group of R3c and an average crystallite size of 25 nm. UV–visible diffuse reflectance spectroscopy revealed an absorption cut-off wavelength near 590 nm, corresponding to a band gap of 2.08 eV, indicating the capability of BFO NPs to absorb visible light within the 400–590 nm range. BFO NPs have shown efficient and rapid photocatalytic degradation of methylene blue (MB) in acidic, neutral, and basic pH conditions under natural sunlight. This is attributed to the intrinsic ferroelectric and ferromagnetic ordering present in synthesized BFO NPs which facilitates the separation and migration of photoinduced charges through band bending phenomena at the interface.","lang":"eng"}],"scopus_import":"1","department":[{"_id":"MaIb"}],"_id":"18558","acknowledgement":"Simant Kumar Srivastav greatly acknowledges the University Grant Commission (UGC), New Delhi, India for providing BSR start-up grant to carry out this research work.\r\nThis research was supported by start-up grant of the University Grant Commission (UGC), New Delhi, India through project no F-30-500/2019 (BSR).","external_id":{"isi":["001348590700001"]},"publisher":"Springer Nature","oa_version":"None","month":"02","article_type":"original","publication_identifier":{"issn":["0928-0707"],"eissn":["1573-4846"]},"researchdata_availability":"not applicable","volume":113,"intvolume":"       113","quality_controlled":"1","type":"journal_article","OA_type":"closed access","status":"public","fulldoi":"https://doi.org/10.1007/s10971-024-06607-2","isi":1,"publication_status":"published","title":"Efficient and rapid sunlight-driven photocatalytic degradation of methylene blue dye using multiferroic BiFeO3 nanoparticles","dataavailabilitystatement":"No datasets were generated or analyzed during the current study.","language":[{"iso":"eng"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","page":"356-373","article_processing_charge":"No","supplementarymaterial":"yes"},{"acknowledgement":"This work was partly supported by the Institute of Information & Communications Technology Planning & Evaluation (IITP) grant funded by the Korea government (MSIT) (No.RS-2021-II210077) and Korea Institute of Energy Technology Evaluation and Planning (KETEP) grant funded by the Korea government (MOTIE)(RS-2024-00398346, ESS BigData-Based O&M and Asset Management Technical Manpower Training).","department":[{"_id":"MaIb"}],"_id":"18701","publisher":"Elsevier","oa_version":"None","month":"03","external_id":{"isi":["001433664000001"]},"intvolume":"       382","publication_identifier":{"eissn":["1873-4979"],"issn":["0167-577X"]},"article_type":"original","volume":382,"researchdata_availability":"upon request","quality_controlled":"1","article_number":"137869","citation":{"mla":"Mahato, Neelima, et al. “In-Situ Engineered Highly-Crystalline Polythiophene Empowered Electrochemical Capacitor-II: Anomalous Electrochemical Charge Storage Behavior of Polythiophene-RGO Composite.” <i>Materials Letters</i>, vol. 382, 137869, Elsevier, 2025, doi:<a href=\"https://doi.org/10.1016/j.matlet.2024.137869\">10.1016/j.matlet.2024.137869</a>.","ieee":"N.

These kinds of membranes separated internal reactions from the outside chaos while staying flexible so that those primordial cells can move, adopt their shape and, most importantly, propagate. Such membrane plasticity still remains a defining feature of all modern cell types. This remarkable ability to change their shape is most prominently observed during their propagation (i.e., cell division). Throughout division, a cell undergoes drastic change in its shape, usually at the middle of the cell, pulling the two opposite membrane sides inward, closer to each other, and, finally, culminating in pinching off to separate the cell into two daughter cells. To achieve this, a cell needs to employ a protein machinery, usually termed divisome, that can coordinate all necessary intracellular processes with membrane remodelling and synthesis of other extracellular structures that decorate a cell. The focus of this dissertation is a membrane-remodelling FtsZ system that is present across all domains of life. FtsZ forms filaments that further self-organize into ring-like structures at the cell septum and together with other division proteins perform cell envelope synthesis and constriction. However, there are still knowledge gaps in our mechanistic understanding of division in both archaea and bacteria. My work presented in this dissertation centres around a simple yet not well understood question: How is the divisome positioned correctly at the mid-cell? To achieve the proper positioning, the divisome needs to (i) be recruited to the mid-cell and (ii) localized orthogonally to the long cell axis. I tackle these processes in two different systems by applying an in vitro biochemical bottom-up reconstitution approach. I use purified components of Haloferax volcanii and Escherichia coli divisome to explore how divisome is recruited to the mid-cell in archaea and how the Z-ring positions orthogonally to the long cell axis in bacteria, respectively. \r\n\r\nFirstly, I collaborate with archaeal cell and structural biologists to explore the assembly of early division proteins in two FtsZ-containing archaeon H. volcanii, a standard model system for understudied archaeal organisms. I particularly address the hierarchy of interactions that allow a tripartite complex formation (SepF-CdpB1-CdpB2) and how the hierarchy of interactions ultimately leads to the recruitment of FtsZ filaments to the septum. This part of work has been published in (Nußbaum et al., 2024). In collaboration with evolutionary biologists, I shed light on ancient features that archaeal divisome has retained to this day and also speculate on a property that it might have lost during the course of evolution. \r\n\r\nNext, I switch my attention to E. coli divisome. Particularly, I address the FtsZ’s intrinsic biophysical property that drives the Z-ring diameter, and thereby the perpendicular orientation of the Z-ring to the long cell axis based on suggested membrane curvature sensing mechanism (Vanhille-Campos et al., 2024). This property allows formation of different Z-ring diameters that match the variety of cell diameters present in prokaryotes. The results showcase that the distribution of charged amino acids in the intrinsically disordered linker at the C-terminus (CTL) of FtsZ is the major determining factor of Z-ring diameter with inter-CTL interactions as an underlying mechanism. \r\n\r\nFinally, I thoroughly explain the methodology I used to address the abovementioned projects, and I finish with a discussion on how early archaeal divisome assembly and curvature sensing mechanism in bacteria, at first sight unrelated topics, are interconnected and important groundwork for both fundamental and translational research.

In contrast to classical rotations, quantum mechanics unveils the SO(3) symmetry group structure, manifesting in phenomena without classical counterparts, from angular momentum quantization to non-trivial addition of angular momenta.\r\nWhile most studies of topological physics have focused on two-band systems, the SO(3) symmetry group of quantum rotors offers an inherently more complex platform with unprecedented possibilities for exploring topological phenomena. Despite their ubiquity in nature– from molecules to nanorotors– their potential for hosting topological phases has remained largely unexamined.\r\nIn this thesis, we mainly focus on periodically driven linear molecules as a prototype for studying topological phenomena in quantum rotors. Recent technological advances in coherent control of molecules, particularly through precisely shaped laser pulses, have made it possible to investigate linear rotors in the context of topology. While planar rotors have received some attention in recent years, threedimensional rotors–particularly linear molecules–harbor substantially richer topological phenomena due to their non-abelian nature and their additional angular degrees of freedom. We demonstrate that these systems can host novel edge states and topological features fundamentally impossible in planar systems.\r\nWe begin by establishing a theoretical bridge between periodically kicked rotors and \"crystalline\" lattices in angular momentum space. Using non-interacting linear molecules as our primary example, we show how quantum interference and revival patterns lead to the possibility to simulate band models with arbitrary number of bands N. While our framework applies to various quantum rotors, including nanorotors and kicked Bose-Einstein condensates, linear\r\nmolecules provide an ideal experimental platform due to their abovementioned precise controllability.\r\nThe core of this work examines adiabatic dynamics of 3D quantum rotors, establishing a geometric framework based on the Euler class to characterize its non-abelian topology. The non-Hermitian nature of the system enables novel braiding behaviors and topological transitions impossible in static systems, leading to an anomalous Dirac string phase with edge states in each gap, even though the Berry phases are all zero. These features can be directly observed through\r\nmolecular alignment and rotational level populations.\r\nThese findings establish quantum rotors as an alternative platform for studying multi-band topological physics, while suggesting practical implementations for quantum computation where topological protection could offer natural resilience against decoherence. The rich structure of three-dimensional rotation groups, combined with the tunability of topological features through driving parameters, makes this platform particularly valuable for exploring fundamental\r\nphysics and developing quantum technologies."}],"language":[{"iso":"eng"}],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","short":"CC BY-NC-ND (4.0)"},"page":"192","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","file_date_updated":"2025-03-20T08:02:35Z","article_processing_charge":"No","has_accepted_license":"1","related_material":{"record":[{"id":"12788","status":"public","relation":"part_of_dissertation"},{"status":"public","id":"9903","relation":"part_of_dissertation"},{"status":"public","id":"19425","relation":"part_of_dissertation"},{"status":"public","id":"14851","relation":"part_of_dissertation"},{"status":"public","id":"15004","relation":"part_of_dissertation"}]},"oa":1,"corr_author":"1","OA_place":"publisher","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","type":"dissertation","OA_type":"gold","degree_awarded":"PhD","ddc":["530"],"status":"public","fulldoi":"https://doi.org/10.15479/AT-ISTA-19393","publication_status":"published","title":"Non-equilibrium topological phases with periodically driven molecules and quantum rotors","file":[{"file_name":"thesis_final.pdf","access_level":"open_access","date_created":"2025-03-12T12:56:46Z","content_type":"application/pdf","date_updated":"2025-03-12T12:56:46Z","success":1,"relation":"main_file","checksum":"d3ab25782c7ea38ce9910e57d25f6733","creator":"vkarle","file_id":"19394","file_size":10625143},{"checksum":"3ccfb0aeba4d860d71e18347913034e4","creator":"vkarle","file_size":23119202,"file_id":"19400","access_level":"closed","file_name":"thesis.zip","content_type":"application/zip","date_created":"2025-03-13T13:15:10Z","date_updated":"2025-03-20T08:02:35Z","relation":"source_file"}]},{"corr_author":"1","OA_place":"publisher","language":[{"iso":"eng"}],"tmp":{"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","short":"CC BY (4.0)"},"page":"501-514.e18","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","has_accepted_license":"1","article_processing_charge":"Yes (via OA deal)","file_date_updated":"2025-01-27T08:46:33Z","related_material":{"record":[{"relation":"earlier_version","id":"18688","status":"public"}]},"oa":1,"fulldoi":"https://doi.org/10.1016/j.cell.2024.11.022","isi":1,"publication_status":"published","title":"Human hippocampal CA3 uses specific functional connectivity rules for efficient associative memory","project":[{"call_identifier":"H2020","name":"Biophysics and circuit function of a giant cortical glutamatergic synapse","_id":"25B7EB9E-B435-11E9-9278-68D0E5697425","grant_number":"692692"},{"call_identifier":"H2020","name":"Synaptic computations of the hippocampal CA3 circuitry","_id":"fc2be41b-9c52-11eb-aca3-faa90aa144e9","grant_number":"101026635"},{"grant_number":"26137","_id":"6285a163-2b32-11ec-9570-8e204ca2dba5","name":"Studying Organelle Structure and Function at Nanoscale Resolution with Expansion Microscopy"},{"call_identifier":"FWF","_id":"2548AE96-B435-11E9-9278-68D0E5697425","grant_number":"W1232","name":"Molecular Drug Targets"},{"grant_number":"PAT 4178023","_id":"8d9195e9-16d5-11f0-9cad-d075be887a1e","name":"Synaptic networks of human brain"},{"_id":"9B861AAC-BA93-11EA-9121-9846C619BF3A","name":"NOMIS Fellowship Program"}],"file":[{"date_created":"2025-01-27T08:46:33Z","content_type":"application/pdf","file_name":"2025_Cell_Watson.pdf","access_level":"open_access","relation":"main_file","success":1,"date_updated":"2025-01-27T08:46:33Z","creator":"dernst","checksum":"d5a818edc32d249cdf75e1bb5b70a4b7","file_id":"18884","file_size":14082343}],"type":"journal_article","OA_type":"hybrid","ddc":["570"],"ec_funded":1,"status":"public","publication_identifier":{"issn":["0092-8674"],"eissn":["1097-4172"]},"article_type":"original","volume":188,"intvolume":"       188","pmid":1,"issue":"2","quality_controlled":"1","department":[{"_id":"JoDa"},{"_id":"PeJo"},{"_id":"GradSch"}],"_id":"18879","acknowledgement":"We thank Florian Marr for excellent technical assistance, Christina Altmutter and Julia Flor for technical support, Alois Schlögl for programming, Todor Asenov for development of the transportation box for human brain tissue, Tim Vogels for guidance on simulations, Marcus Huber for mathematical advice, Walter Kaufmann for assistance with handling frozen tissue, and Eleftheria Kralli-Beller for manuscript editing.

Combining multicellular patch-clamp recording with expansion-based superresolution microscopy and full-scale modeling, we determined the cellular and microcircuit properties of the human hippocampal CA3 region, a fundamental circuit for memory storage. In contrast to neocortical networks, human hippocampal CA3 displayed sparse connectivity, providing a circuit architecture that maximizes associational power. Human synapses showed unique reliability, high precision, and long integration times, exhibiting both species- and circuit-specific properties. Together with expanded neuronal numbers, these circuit characteristics greatly enhanced the memory storage capacity of CA3.

Here, we show that lateral mesendoderm (LME) cells in the early zebrafish gastrula use the ectoderm as their substrate for migration. We show that the lateral ectoderm is permissive for the animal-pole-directed migration of LME cells, while the ectoderm at the animal pole halts it. These differences in permissiveness depend on the lateral ectoderm being more cohesive than the animal ectoderm, a property controlled by bone morphogenetic protein (BMP) signaling within the ectoderm.

Here we show that spermatogenesis in the liverwort Marchantia polymorpha involves two waves of extensive DNA methylation reprogramming. First, 5-methylcytosine (5mC) expands from transposons to the entire genome. Notably, the second wave installs 4mC throughout genic regions, covering over 50% of CG sites in sperm. 4mC requires a methyltransferase (MpDN4MT1a) that is specifically expressed during late spermiogenesis. Deletion of MpDN4MT1a alters the sperm transcriptome, causes sperm swimming and fertility defects, and impairs post-fertilization development. Our results reveal extensive 4mC in a eukaryote, identify a family of eukaryotic methyltransferases, and elucidate the biological functions of 4mC in reproductive development, thereby expanding the repertoire of functional eukaryotic DNA modifications."}],"scopus_import":"1","date_published":"2025-05-29T00:00:00Z","day":"29","doi":"10.1016/j.cell.2025.03.014","acknowledged_ssus":[{"_id":"Bio"},{"_id":"ScienComp"}],"author":[{"full_name":"Walker, James","last_name":"Walker","first_name":"James"},{"full_name":"Zhang, Jingyi","last_name":"Zhang","first_name":"Jingyi"},{"first_name":"Yalin","last_name":"Liu","full_name":"Liu, Yalin"},{"last_name":"Xu","id":"9724dd9d-f591-11ee-bd51-e97ed0652286","first_name":"Shujuan","full_name":"Xu, Shujuan"},{"full_name":"Yu, Yiming","orcid":"0000-0002-9919-7282","id":"318e643b-8b61-11ed-b69e-aafa103ec8dd","first_name":"Yiming","last_name":"Yu"},{"first_name":"Martin","last_name":"Vickers","full_name":"Vickers, Martin"},{"id":"fec73395-8b60-11ed-b69e-927fda99c743","first_name":"Weizhi","last_name":"Ouyang","full_name":"Ouyang, Weizhi"},{"first_name":"Judit","last_name":"Tálas","full_name":"Tálas, Judit"},{"full_name":"Dolan, Liam","last_name":"Dolan","first_name":"Liam"},{"first_name":"Keiji","last_name":"Nakajima","full_name":"Nakajima, Keiji"},{"last_name":"Feng","id":"e0164712-22ee-11ed-b12a-d80fcdf35958","first_name":"Xiaoqi","orcid":"0000-0002-4008-1234","full_name":"Feng, Xiaoqi"}],"date_updated":"2026-10-20T08:22:21Z","citation":{"chicago":"Walker, James, Jingyi Zhang, Yalin Liu, Shujuan Xu, Yiming Yu, Martin Vickers, Weizhi Ouyang, et al. “Extensive N4 Cytosine Methylation Is Essential for Marchantia Sperm Function.” <i>Cell</i>.

The dramatic expansion of the brain that diverges its shape from the spinal cord follows neural tube closure during embryonic development. Here, we show that this differential deformation is encoded by a pre-pattern of tissue material properties in chicken embryos. Using magnetic droplets and atomic force microscopy, we demonstrate that the dorsal hindbrain is more fluid than the dorsal spinal cord, resulting in a thinning versus a resisting response to increasing lumen pressure, respectively. The dorsal hindbrain exhibits reduced apical actin and a disorganized laminin matrix consistent with tissue fluidization. Blocking the activity of neural-crest-associated matrix metalloproteinases inhibits hindbrain expansion. Transplanting dorsal hindbrain cells to the spinal cord can locally create an expanded brain-like morphology in some cases. Our findings raise questions in vertebrate head evolution and suggest a general role of mechanical pre-patterning in sculpting epithelial tubes.","lang":"eng"}],"scopus_import":"1","date_updated":"2026-10-20T08:25:00Z","author":[{"last_name":"Mclaren","first_name":"Susannah B.P.","full_name":"Mclaren, Susannah B.P."},{"last_name":"Xue","first_name":"Shi-lei","id":"31D2C804-F248-11E8-B48F-1D18A9856A87","full_name":"Xue, Shi-lei"},{"full_name":"Ding, Siyuan","last_name":"Ding","first_name":"Siyuan"},{"first_name":"Alexander K.","last_name":"Winkel","full_name":"Winkel, Alexander K."},{"last_name":"Baldwin","first_name":"Oscar","full_name":"Baldwin, Oscar"},{"full_name":"Dwarakacherla, Shreya","first_name":"Shreya","last_name":"Dwarakacherla"},{"last_name":"Franze","first_name":"Kristian","full_name":"Franze, Kristian"},{"orcid":"0000-0001-6005-1561","full_name":"Hannezo, Edouard B","last_name":"Hannezo","first_name":"Edouard B","id":"3A9DB764-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Xiong","first_name":"Fengzhu","full_name":"Xiong, Fengzhu"}],"publication":"Developmental Cell","citation":{"chicago":"Mclaren, Susannah B.P., Shi-lei Xue, Siyuan Ding, Alexander K.

Here, we characterize Kiwa, a widespread two-component system composed of the transmembrane sensor KwaA and the DNA-binding effector KwaB. Cryogenic electron microscopy (cryo-EM) analysis reveals that KwaA and KwaB assemble into a large, membrane-associated supercomplex. Upon phage binding, KwaA senses infection at the membrane, leading to KwaB binding of ejected phage DNA and inhibition of replication and late transcription, without inducing host cell death. Although KwaB can bind DNA independently, its antiviral activity requires association with KwaA, suggesting spatial or conformational regulation. We show that the phage-encoded DNA-mimic protein Gam directly binds and inhibits KwaB but that co-expression with the Gam-targeted RecBCD system restores protection by Kiwa. Our findings support a model in which Kiwa coordinates membrane-associated detection of phage infection with downstream DNA binding by its effector, forming a spatially coordinated antiviral mechanism.","lang":"eng"}],"scopus_import":"1","doi":"10.1016/j.cell.2025.07.002","day":"16","date_published":"2025-10-16T00:00:00Z","date_created":"2025-08-07T05:00:04Z","year":"2025","citation":{"apa":"Zhang, Z., Todeschini, T.

Owing to the lack of structurally resolved Orai1/STIM1 complexes, the impact of their coupling on individual Orai1 transmembrane domain (TM) movements is unclear. This study investigates STIM1-independent and STIM1-dependent Orai1-TM dynamics using photocrosslinking unnatural amino acids (UAAs) at each individual TM position. We primarily identify CRAC-channel-like currents directly after UAA incorporation or additional UV-light irradiation at TM3 sites that interface with non-pore-lining TMs. Using UAAs combined with conventional site-directed mutagenesis and molecular dynamics simulations, we discover that pore opening involves a widening of interfaces formed by TM3 with non-pore-lining TMs. Orai1 mutants with a UAA in TM3 exhibit weaker STIM1-induced activation after UV exposure, possibly caused by a restricted widening of non-pore-lining TM interfaces. We demonstrate that photocrosslinking UAAs are excellent tools for improving our understanding of key determinants and ion channel dynamics modulating pore opening.","lang":"eng"}],"DOAJ_listed":"1","date_published":"2025-06-18T00:00:00Z","day":"18","doi":"10.1016/j.xcrp.2025.102623","author":[{"first_name":"Hadil","last_name":"Najjar","full_name":"Najjar, Hadil"},{"last_name":"Weiß","first_name":"Sarah","full_name":"Weiß, Sarah"},{"full_name":"Horvath, Ferdinand","first_name":"Ferdinand","id":"b0dc7f61-21a3-11ef-a9b4-e6ab1aa6f21e","last_name":"Horvath"},{"first_name":"Valentina","last_name":"Hopl","full_name":"Hopl, Valentina"},{"first_name":"Adéla","last_name":"Tiffner","full_name":"Tiffner, Adéla"},{"full_name":"Höbarth, Lorenz","last_name":"Höbarth","first_name":"Lorenz"},{"first_name":"Julia","last_name":"Söllner","full_name":"Söllner, Julia"},{"full_name":"Fröhlich, Maximilian","first_name":"Maximilian","last_name":"Fröhlich"},{"full_name":"Prantl, Magdalena","first_name":"Magdalena","last_name":"Prantl"},{"full_name":"Müller, Nora","last_name":"Müller","first_name":"Nora"},{"full_name":"Nazarenko, Yuliia","last_name":"Nazarenko","first_name":"Yuliia"},{"last_name":"Harant","first_name":"Selina","full_name":"Harant, Selina"},{"last_name":"Weissenböck","first_name":"Lukas","full_name":"Weissenböck, Lukas"},{"full_name":"Grabmayr, Herwig","first_name":"Herwig","last_name":"Grabmayr"},{"full_name":"Sallinger, Matthias","first_name":"Matthias","last_name":"Sallinger"},{"last_name":"Maltan","first_name":"Lena","full_name":"Maltan, Lena"},{"first_name":"Linda V.","last_name":"Echefu","full_name":"Echefu, Linda V."},{"full_name":"Radiskovic, Tamara","last_name":"Radiskovic","first_name":"Tamara"},{"last_name":"Leopold","first_name":"Melanie","full_name":"Leopold, Melanie"},{"full_name":"Lindinger, Sonja","last_name":"Lindinger","first_name":"Sonja"},{"first_name":"Christina","last_name":"Humer","full_name":"Humer, Christina"},{"full_name":"Höglinger, Carmen","first_name":"Carmen","last_name":"Höglinger"},{"last_name":"Krobath","first_name":"Heinrich","full_name":"Krobath, Heinrich"},{"last_name":"Renger","first_name":"Thomas","full_name":"Renger, Thomas"},{"first_name":"Isabella","last_name":"Derler","full_name":"Derler, Isabella"}],"date_updated":"2026-10-20T08:25:34Z","citation":{"chicago":"Najjar, Hadil, Sarah Weiß, Ferdinand Horvath, Valentina Hopl, Adéla Tiffner, Lorenz Höbarth, Julia Söllner, et al. “STIM1-Induced Widening of Non-Pore-Lining TM Interfaces Is Crucial for Orai1 Pore Opening.” <i>Cell Reports Physical Science</i>.

The key factors regulating vacuolar acidification and underlying mechanisms remain unclear. Here, we report that Arabidopsis phospholipase Dζ2 (PLDζ2) promotes the acidification of the vacuolar lumen to stimulate autophagic degradation under phosphorus deficiency. The pldζ2 mutant massively accumulates autophagic structures while exhibiting premature leaf senescence under nutrient starvation. Impaired autophagic flux, lytic vacuole morphology, and lytic degradation in pldζ2 indicate that PLDζ2 regulates autophagy by affecting the vacuolar function. PLDζ2 locates in both tonoplast and cytoplasm. Genetic, structural, and biochemical studies demonstrate that PLDζ2 directly interacts with vacuolar-type ATPase (V-ATPase) subunit D (VATD) to promote vacuolar acidification and autophagy under phosphorus starvation. These findings reveal the importance of V-ATPase and vacuolar pH in autophagic activity and provide clues in elucidating the regulatory mechanism of vacuolar acidification."}],"doi":"10.1016/j.celrep.2025.116024","day":"22","date_published":"2025-07-22T00:00:00Z","year":"2025","date_created":"2025-07-20T22:02:01Z","citation":{"chicago":"Guan, Bin, Ke Xuan Xie, Xin Qiao Du, Yu Xuan Bai, Peng Chao Hao, Wen Hui Lin, Jiří Friml, and Hong Wei Xue. “Arabidopsis Phospholipase Dζ2 Facilitates Vacuolar Acidification and Autophagy under Phosphorus Starvation by Interacting with VATD.” <i>Cell Reports</i>.

Proteasome regulator 1 (PTRE1), a positive regulator of proteasome activity, has been implicated in auxin-mediated proteasome suppression; however, the mechanism by which auxin modulates PTRE1 function remains unclear. Here, we demonstrate that auxin promotes the interaction between germin-like protein 1 (GLP1) and PTRE1, facilitating PTRE1 retention at the plasma membrane. The relocation of PTRE1 results in reduced nuclear 26S proteasome activity, and thus the attenuated Aux/IAA degradation and altered Aux/IAA homeostasis, ultimately resulting in suppressed auxin-mediated transcriptional regulation. Our findings uncover a previously uncharacterized regulatory axis in auxin signaling that controls Aux/IAA protein stability, functioning alongside the TIR1- and TRANSMEMBRANE KINASE 1 (TMK1)-mediated pathways, and highlight the coordination of auxin signaling from the cell surface to the nucleus via auxin-induced PTRE1 relocation, which fine-tunes Aux/IAA protein homeostasis and auxin responses."}],"doi":"10.1016/j.celrep.2025.116056","date_published":"2025-07-24T00:00:00Z","DOAJ_listed":"1","day":"24","acknowledgement":"The study was supported by the National Natural Science Foundation of China (NSFC; 32230011, 91954206, and 31721001).
