We examine a broad class of slip boundary conditions that generalises the commonly used Navier slip, perfect slip, stick-slip and Tresca friction boundary conditions. In particular, set-valued, nonmonotone, noncoercive and dynamic relations may occur. For a unifying framework of such relations, we present a fully discrete numerical scheme for the time-dependent Navier–Stokes equations subject to impermeability and general slip-type boundary conditions on polyhedral domains. Based on compactness arguments, we prove convergence of subsequences, finally ensuring the existence of a weak solution. The numerical scheme uses a general inf-sup stable pair of finite element spaces for the velocity and pressure, a regularisation approach for the implicit slip boundary condition and, most importantly, a general Nitsche method to impose the impermeability and a backward Euler time stepping. One of the key tools in the convergence proof is an inhomogeneous Korn inequality that includes a normal trace term. article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Pablo Alexei full_name: Gazca-Orozco, Pablo Alexei last_name: Gazca-Orozco - first_name: Franz full_name: Gmeineder, Franz last_name: Gmeineder - first_name: Erika full_name: Maringová, Erika id: dbabca31-66eb-11eb-963a-fb9c22c880b4 last_name: Maringová - first_name: Tabea full_name: Tscherpel, Tabea last_name: Tscherpel citation: ama: Gazca-Orozco PA, Gmeineder F, Maringová E, Tscherpel T.

Here, we present a mismatch-assisted microstructure engineering strategy in which Ag2Se particles are treated with polyanionic ZnSe complexes and consolidated through the β–α transition to introduce ZnSe nanoprecipitates, Ag2Se/ZnSe interfaces, and local strain fields. The crystallographic mismatch between ZnSe and Ag2Se, together with the Zn2+/Ag+ size difference, amplifies phase-transition-induced deformation and promotes high-density dislocations with periodic strain modulations. This defect architecture suppresses grain coarsening, removes excess Ag, limits Ag-interstitial formation, and reduces lattice thermal conductivity through lattice softening and multiscale phonon scattering. Ag2Se–4%ZnSe nanocomposites achieve a peak zTmax of 1.13 at 369 K and a zTavg of 1.08 from 300 to 380 K, demonstrating mismatch-driven defect engineering through the β–α phase transition as a route for optimizing Ag2Se-based thermoelectrics. acknowledged_ssus: - _id: EM-Fac - _id: LifeSc - _id: NanoFab - _id: MassSpec acknowledgement: 'Open access funding provided by Institute of Science and Technology Austria.

Approaching standardization and reference methods early is foundational for reproducibility and comparability across laboratories and reduction of systematic error sources. It underpins trust in data obtained and accelerates innovation by ensuring that scientists work from a common methodological baseline. Accordingly, obtaining reproducible results from different GISAS instruments requires an agreement on how measurements are performed, instruments calibrated and terms defined. To pave the way for standardization and reference methods, we surveyed GISAS practitioners on what comes before an experiment: hardware, software, sample alignment and instrument calibration. Twenty-two questions were designed to elucidate the state of the art, which can be used for the development of reference methods. Our data on 27 instruments provide the basis for standardization. With very few exceptions, we found laboratories prepared to implement future reference methods, but no consensus emerges naturally for sample alignment and instrument calibration. We, that is the GISAS community, are thus in a position to embark on the journey of standardization.' acknowledgement: "The authors thank all respondents for their participation in the\r\nquestionnaire.

We combined Mosaic Analysis with Double Markers at embryonic stages (E)12.5 and E13.5 with early postnatal callosal tracing to dissect RGP lineage progression. We find that multipotent RGPs generate all extra-telencephalic (ET) and intra-telencephalic (IT) PNs via parallel sublineages that emerge simultaneously at neurogenesis onset. ET-PN production progresses exclusively via small, self-consuming lineages; IT-PN lineages feature RGPs generating large translaminar outputs. The early emergence of IT-PN–fated RGPs, coinciding with a switch to direct neurogenesis, contributes to the stereotyped population-level progression of the multipotent lineage. We also identify POU3F transcription factors as candidate regulators of IT-PN fate via noncanonical mitotic chromatin binding. The results support a model whereby IT- and ET-PNs arise from an early bifurcation and parallel specification within the multipotent RGP lineage. acknowledgement: 'We thank M. caouyette for the plasmid construction for Pou3f1overexpression; d.

In Drosophila, sleep loss has been shown to trigger plasticity of the presynaptic active zone, marked by increasing levels of the ELKS-family scaffold protein Bruchpilot (BRP). By titrating brp gene copy number, we previously established a presynapse-specific, dosage-dependent paradigm that modulates sleep pressure. Here, to elucidate the molecular landscape of this plasticity, we performed synapse-enriched integrated-omics. Proteomic and bioinformatic analyses revealed changes in immune and stress response pathways and local translation control. Strikingly, phospho-proteomic analysis uncovered a global shift toward hypophosphorylation, particularly in presynaptic proteins, indicating a reprogramming of the phosphorylation–dephosphorylation balance. This presynaptic hypophosphorylation is likely contributed by reduced activity of Protein Kinase A (PKA) and enhanced substrate affinity of Protein Phosphatase 1 (PP1) mediated by its regulatory subunit Spinophilin (Spn). Manipulating either PKA or PP1 activity was sufficient to suppress BRP-modulated sleep phenotypes. We propose that presynaptic hypophosphorylation constitutes a molecular signature of local synaptic remodeling that adaptively tunes sleep need via reversible posttranslational modification, a mechanism likely conserved across species. article_number: e2524065123 article_processing_charge: Yes (in subscription journal) article_type: original author: - first_name: Chengji full_name: Piao, Chengji last_name: Piao - first_name: Ewelina full_name: Dutkiewicz, Ewelina id: 0601cc46-c082-11ec-9b07-bb29641d1de9 last_name: Dutkiewicz - first_name: Laxmikanth full_name: Kollipara, Laxmikanth last_name: Kollipara - first_name: Albert full_name: Sickmann, Albert last_name: Sickmann - first_name: Sheng full_name: Huang, Sheng last_name: Huang - first_name: Stephan J. full_name: Sigrist, Stephan J. last_name: Sigrist citation: ama: Piao C, Dutkiewicz E, Kollipara L, Sickmann A, Huang S, Sigrist SJ.

However, the long cultivation cycle and susceptibility to diseases hinder the advancement of the ginseng industry. Here, we demonstrate that the embryonic protoderm of ginseng can efficiently produce ginsenosides. Single-cell transcriptome and mass spectrometry imaging analyses reveal that ginsenosides accumulate in the protoderm of ginseng embryonic callus (EC) at levels comparable to those in forest ginseng. Epigenetic analyses indicate that elevated histone acetylation and enhanced chromatin accessibility at regeneration- and ginsenoside metabolism-related gene loci are associated with the ginsenoside-producing capacity of EC. Increasing histone acetylation levels or overexpressing the regeneration-related WUSCHEL-RELATED HOMEOBOX11 (WOX11) gene further enhances ginsenoside production in EC. Our findings suggest that the protoderm of EC could serve as an in situ biological compartment for high-efficiency ginsenoside producion, offering a complementary approach to traditional ginseng cultivation. acknowledgement: 'The authors are grateful to Professor Linfeng Li from the School of Life Science, Fudan University, for his assistance during the ginseng genome annotation.

However, in single-molecule circuits this magnetic field is usually weak. Here we show that radially π-conjugated carbon structures can support amplified circulating currents that generate local magnetic fields. Within tight-binding and density functional theory (DFT) frameworks, we first study cycloparaphenylene (CPP) junctions where both electrodes are attached to the same phenylene unit on the nanohoop. We observe an energy-dependent ring current component that traverses the whole macrocycle by mapping the local current density. Importantly, we find that destructive interference near degenerate resonances can reverse the ring current direction and amplify it strongly relative to the source–drain current. We show that this interference-driven design principle is general, and also carries over to C60 junctions. In fullerene, lower-lying degenerate resonances are more easily accessible through electrostatic gating, reaching a magnetic field of 14.2 mT under a 100 mV source–drain bias. This work thus provides new insights into ring currents in radially π-conjugated carbon structures and highlights their potential as design platforms for single-molecule electromagnets. acknowledgement: The authors thank Jascha Repp from the University of Regensburg for helpful discussions.

NMR spectroscopy provides this insight at atomic resolution, yet for large proteins the difficulty of resonance assignment has largely confined such studies to systems below ∼50 kDa, or to observing only methyl groups. Here we present an integrated magic-angle spinning (MAS) and solution NMR study of the 134 kDa tetrameric malate dehydrogenase from Ignicoccus islandicus (IiMDH), an enzyme of particular interest as an evolutionary intermediate between allosteric lactate\r\ndehydrogenases and non-allosteric malate dehydrogenases. By combining high-dimensional (up to 4D) MAS NMR experiments on sedimented protein with solution NMR, we achieved 92% backbone heavy- atom assignment and 91% assignment of all Ile-δ1, Leu-δ1/-δ2, Val-γ1/-γ2, Met-ε and Thr-γ methyl groups. Building on these assignments, we use various probes of backbone and sidechain dynamics: elevated MAS NMR 15N rotating-frame relaxation (R1ρ) points to microsecond motions in functionally critical regions, including the catalytic loop and the mobile surface loop. Complementary methyl-axis order parameters from solution NMR identified additional flexible sites in the hydrophobic core. Chemical shift perturbation experiments upon addition of the substrate analogue oxamate, monitored via backbone 1H-15N TROSY, revealed both active-site contacts and responses in helices α2F and α3G, regions implicated in allosteric signal transmission. The integrated approach demonstrated here exploits the distinct strengths of MAS and solution NMR, and provides a comprehensive view of structure, dynamics, and substrate interactions in a large oligomeric enzyme that would not be accessible by either technique alone." acknowledged_ssus: - _id: NMR - _id: LifeSc acknowledgement: This research was supported by the Scientific Service Units (SSU) of Institute of Science and Technology Austria (ISTA) through resources provided by the Nuclear Magnetic Resonance and the Lab Support Facilities.

How spinal circuits and their cell types evolved to support this transition remains unclear. We leverage frog metamorphosis, which recapitulates this transition within a single organism, to define how spinal circuits generate aquatic versus terrestrial motor patterns. At swim stages, spinal architecture is uniform, with a transcriptionally and anatomically homogeneous motor and interneurons. As limbs develop and their movement complexifies, spinal circuits expand in neuron number and subtype diversity. This expansion is most pronounced for V1 inhibitory neurons, which increase ∼70-fold and diversify into transcriptionally distinct subtypes. Disrupting transcription factors defining emerging motor and V1 populations reveals molecular segregation between swim and limb circuits, highlighting the role of subtype diversity in motor coordination. A multifold increase in inhibitory neuron diversity thus underlies the tail-to-limb locomotor transition, providing a framework for spinal circuit adaptation during vertebrate evolution. acknowledged_ssus: - _id: Bio - _id: LifeSc acknowledgement: 'We would like to thank the members of the Sweeney Lab, Mario de Bono, Michael Forsthofer, Katharina Lust, and Meital Oren, for comments on the manuscript.

Furthermore, we also consider the case of MLS and provide the first lower bound showing that its communication complexity is much worse than previously believed, i.e., it is very far from $ \\log(N) $.\r\nFinally, we also propose a variant of MLS which provably achieves the same security properties with a much lower communication cost." alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Miguel full_name: Cueto Noval, Miguel id: ffc563a3-f6e0-11ea-865d-e3cce03d17cc last_name: Cueto Noval orcid: 0000-0002-2505-4246 citation: ama: Cueto Noval M.

The objects of interest can be often realized as cohomological invariants of algebraic\r\nvarieties, and good understanding of their geometry sheds light into the original questions.\r\nSuch techniques have seen immense applications in the Langlands program, where they go\r\nunder the label of geometric representation theory.\r\n\r\nOne source of powerful invariants in algebraic geometry comes from algebraic K-theory,\r\nHochschild homology, and their relatives. These localizing invariants contain large amount\r\nof information, but are quite hard to compute. For this reason, their usage in geometric\r\nrepresentation theory has been limited.\r\n\r\nThe aim of this thesis is to showcase how to control such invariants in the situations of\r\ninterest and use them to obtain new insights. We start by reinterpreting equivariant Hochschild\r\nhomology in terms of functions on certain fixed-point schemes, which are of independent\r\ninterest. We compare it to equivariant K-theory via the trace map. We give new computations\r\nand comparisons of such invariants of affine Schubert varieties in Gr, including arithmetic\r\nsituations. We show that they behave much better than expected.\r\n\r\nWe finally utilize this circle of ideas in a purely topological setting. We describe the varying\r\nfixed points of the extended torus action on the affine Grassmannian, and use it to compute\r\nits equivariant topological K-theory ring. The answer is nontrivial and verifies an outstanding\r\nconjecture in the subject.\r\n\r\nWe compare, partly conjecturally, the resulting K-theory ring to the completed center of an\r\nintegral even hybrid quantum group and its deformed quantum category O.

We further compare it to the torus-equivariant Hochschild homology of perfect complexes, which has a geometric description in terms of global functions on certain fixed-point schemes. We prove that Fp-linearly, this comparison is an isomorphism. Our approach is quite constructive, resulting in new computations of these K-theory rings. We establish various structural results for equivariant perfect algebraic K-theory on the way; we believe these are of independent interest. acknowledgement: "I would like to thank the following people for fruitful discussions,\r\nhelpful sanity checks or comments on previous drafts: Roman Bezrukavnikov, Jens Niklas Eberhardt, Mischa Elkner, Tamás Hausel, Andres Fernandez Herrero, Adeel Khan,\r\nBernhard Köck, Andrei Konovalov, Quoc Ho, Mirko Mauri, Matthew Morrow, Charanya\r\nRavi, Kamil Rychlewicz, Shyiu Shen, Vladimir Sosnilo, Georg Tamme, Xinwen Zhu.

The plasmid-encoded ParMRC system forms actin-like filaments that segregate low–copy number plasmids. In multicellular cyanobacteria such as Anabaena sp., we found that a chromosomally encoded ParMR system has evolved into a cytoskeletal system named CorMR with a function in cell shape control rather than DNA segregation. Live-cell imaging, in vitro reconstitution, and cryo–electron microscopy revealed that CorM formed dynamically unstable, antiparallel double-stranded filaments that were recruited to the membrane by CorR through an amphipathic helix conserved in multicellular cyanobacteria. CorMR filaments were regulated by MinC, which excluded them from the poles and division plane. Comparative genomics indicated that the repurposing of ParMR and Min systems coevolved with cyanobacterial multicellularity, highlighting the evolutionary plasticity of cytoskeletal systems in bacteria. acknowledged_ssus: - _id: Bio - _id: ScienComp - _id: EM-Fac - _id: LifeSc acknowledgement: "We thank all members of the Loose lab at ISTA for helpful discussions; M.
