Three main ideas have been put forward to explain “faster-X” adaptation. The first is that new beneficial mutations are typically partially recessive with respect to fitness, leading to more efficient selection in hemizygous males. The second is that sex differences in recombination, or sex differences in variance in reproductive success, enhance the effective population size on the X chromosome relative to autosomes. Both ideas have limitations: the first conflicts with theories of dominance, in which beneficial mutations are proposed to be partially dominant, while the second only applies to some taxa. Here we tested a third, newly-proposed theory, in which mutations with large “scaled phenotypic effects” (i.e., large effects relative to the distance to a phenotypic optimum) experience more positive selection on the X. Specifically, we used three proxies for scaled phenotypic effects—amino-acid dissimilarity, amino-acid conservation, and gene age—and estimated X and autosomal rates of adaptation of nonsynonymous mutations across effect-size classes. We did this in three lineages with a well-documented faster-X: Drosophila melanogaster, Mus musculus, and Homo sapiens. As expected, we found that large-effect mutations were more likely to be under purifying selection and less likely to be under positive selection than small-effect mutations. However, contrary to the new theory, faster-X adaptation was not enriched among large-effect mutations. Overall, our results highlight an unresolved gap between patterns of sex chromosome evolution and theories of dominance for fitness.' article_number: evag259 article_processing_charge: Yes article_type: original author: - first_name: Filip full_name: Ruzicka, Filip id: 347955dd-57b0-11ee-9095-c28bdd368f4b last_name: Ruzicka - first_name: Beatriz full_name: Vicoso, Beatriz id: 49E1C5C6-F248-11E8-B48F-1D18A9856A87 last_name: Vicoso orcid: 0000-0002-4579-8306 biorxivid: 1 citation: ama: Ruzicka F, Vicoso B.

Here, we investigated how mild defects in sink phloem differentiation influence whole-plant growth using two Arabidopsis mutants: ops, which exhibits short roots with protophloem differentiation defects, and ops opl2, which displays even shorter roots with combined proto- and metaphloem differentiation defects. Carbon partitioning and phloem transport velocity were compromised in both mutants, with ops opl2 exhibiting stronger effects. Root growth responses to exogenous sucrose highlighted functional differences: only ops opl2 root growth was partially rescued, indicating additional limitations from compromised metaphloem function. Reciprocal grafting confirmed that root growth defects in both mutants are root autonomous. In contrast, source-limited starch mutants with short roots were rescued by sucrose supplementation or by grafting wild-type scions, highlighting that the growth limitation in the roots of phloem mutants is not solely due to carbon shortage. Impaired root phloem also restricted wild-type scion growth, revealing feedback from sink phloem integrity on source activity. Together, these findings show that sink phloem development supports sink function and mediates systemic feedback shaping whole-plant growth. Targeted modulation of sink phloem development could help optimize source–sink relations and improve crop performance.' article_processing_charge: Yes (in subscription journal) article_type: original author: - first_name: Kai full_name: Bartusch, Kai id: 0c51b9f5-90c8-11f1-b4ef-9ad5d3d9a34a last_name: Bartusch orcid: 0000-0003-2708-5545 - first_name: Tina B full_name: Schreier, Tina B last_name: Schreier - first_name: Michaela full_name: Fischer-Stettler, Michaela last_name: Fischer-Stettler - first_name: Samuel C full_name: Zeeman, Samuel C last_name: Zeeman - first_name: Elisabeth full_name: Truernit, Elisabeth last_name: Truernit citation: ama: Bartusch K, Schreier TB, Fischer-Stettler M, Zeeman SC, Truernit E.

Hypocotyl grafting in Arabidopsis thaliana has become a key method for investigating inter-tissue communication, root-to-shoot transport, and vascular regeneration. Here, we describe a high-throughput hypocotyl grafting protocol that consistently achieves success rates above 90% while minimizing complications, such as adventitious root formation, through an optimized hypocotyl cutting position. Our streamlined approach eliminates the need for silicone tubes and fine forceps, requiring only a standard scalpel for the cutting and joining procedure. With proper training, an experienced user can graft up to 1000 plants per day, facilitating large-scale experiments. Additionally, we present vascular connectivity assays using fluorescent dyes and the adjuvant Adigor to enable phloem and xylem transport analysis across the graft junction without the need for wounding. By simplifying the grafting process while maintaining high efficiency, our protocol makes Arabidopsis grafting more accessible and scalable, facilitating research on long-distance molecular transport, vascular development, and plant biotechnology applications. alternative_title: - Methods in Molecular Biology article_processing_charge: No author: - first_name: Kai full_name: Bartusch, Kai id: 0c51b9f5-90c8-11f1-b4ef-9ad5d3d9a34a last_name: Bartusch orcid: 0000-0003-2708-5545 - first_name: Elisabeth full_name: Truernit, Elisabeth last_name: Truernit citation: ama: 'Bartusch K, Truernit E.

In both settings, exact solutions are in\r\ntractable. Fortwo-playerzero-sumconcurrentstochasticgames,valuescanbeirrational,and\r\nthe associated decision problem is SQRT-SUM hard. For multi-player turn-based stochastic\r\ngames,theequilibriumprobabilitiescanbeirrational,anddecidingtheconstrainedexistence\r\nof a Nash equilibrium is undecidable in the presence of memory, and ∃R-complete when the\r\nplayers are restricted to stationary strategies. Hence, in both settings, the natural computational problem is the approximation of the solution within an arbitrary additive error. In\r\nthis thesis, we present improved complexity results and algorithms for such approximation\r\nproblems.\r\nThe first part of the thesis considers two-player zero-sum concurrent stochastic games\r\nwith two classic objectives: (a) stateful-discounted objectives, which are similar to the classic\r\ndiscounted-sum objectives, but states are associated with different discount factors rather\r\nthan a single discount factor; and (b) parity objectives, which are a canonical representation\r\nfor ω-regular objectives. For stateful-discounted objectives, given an ordering of the discount\r\nfactors, the limit value is the limit of the value of the stateful-discounted objectives, as\r\nthe discount factors approach zero according to the given order. The value-approximation\r\nproblem is known to be in EXPSPACE for the limit value of stateful-discounted objectives and\r\nin PSPACEforparityobjectives,andthebest-knownalgorithmsforbothproblemsareatleast\r\nexponential time, with an exponential dependence on the number of states and actions. Our\r\nmain results for the value-approximation problem for the limit value of stateful-discounted\r\nobjectives and parity objectives areas follows: (a)we establish TFNPNP complexity; and (b)we\r\npresent algorithms that improve the dependency on the number of actions in the exponent\r\nfrom linear to logarithmic. In particular, if the number of states is constant, our algorithms\r\nrun in polynomial time.\r\nThe second part of the thesis considers multi-player turn-based stochastic games with\r\nterminal payoffs, where the players are restricted to stationary strategies. We study the\r\napproximate constrained existence problem of Nash equilibria: given a game that has a Nash\r\nequilibrium in which the payoff of every player lies in a given interval, compute a strategy\r\nprofile that is an ε-Nash equilibrium and that satisfies the same constraints up to an additive\r\nerror ε. Our main results are as follows: (a) we present an FNPNP algorithm for the problem;\r\nand(b)we establish that its decision version is NP-hard, already with two players. For the\r\nupperbound,weshowthatifaconstrainedNashequilibriumexists,thenthereexists one\r\nin which the non-zero probabilities are at least an inverse of a double-exponential in the\r\ni\r\ninput size, and that such a strategy profile can be represented, up to an additive error ε, with\r\nfloating-point numbers of polynomial size. We complement the upper bound with a lower\r\nbound on this approach: we present a game with only five players in which every constrained\r\nNash equilibrium requires double-exponentially small probabilities.\r\nThe two parts share a common technical toolkit: bounds on solutions of systems of\r\npolynomial inequalities that arise from real algebraic geometry, the floating-point representation of doubly-exponentially small numbers, and guess-and-verify procedures that resolve\r\nsingle-player games with an NP oracle." acknowledgement: "The research reported in Part I was partially supported by the European Research\r\nCouncil (ERC) Consolidator Grant 863818 (ForM-SMArt), by the Austrian Science Fund\r\n(FWF) 10.55776/COE12, and by the French Agence Nationale de la Recherche (ANR) grant\r\nANR-21-CE40-0020 (CONVERGENCE project).

A central puzzle has been the clear benefit of scaling architecture size and overfitting the training set in supervised learning tasks. This evidence, in apparent contradiction with classical statistical learning theory, pushed researchers to develop a new theory capturing the interplay between the algorithmic and architectural bias of training and the specific target function, differently from previous methods rooted in uniform stability.\r\nThis approach has enabled a grounded understanding of novel learning regimes, typically through formal limits where the number of training samples $n$, data dimensions $d$, and model parameters $p$ grow to infinity at different rates. \\\\\r\nIn this thesis, we follow this approach, focusing on the trustworthiness of high-dimensional models: properties that are difficult to control during training or deployment and often emerge under unpredictable or adversarial conditions. In such settings, it is crucial to formally ensure a priori the reliability of machine learning systems.\r\nFirst, we study data memorization, both as label fitting and as the storage of private information about training samples in trained parameters. We prove that $p = \\Omega(n)$ parameters are sufficient for a deep neural network to memorize a generic set of labels, and for a model to memorize spurious features across training data. We then give evidence that $p = \\Omega(dn)$ parameters are instead necessary for an adversary to reconstruct the full training set from the trained parameters.\r\nSecond, we study robustness, both to adversarial perturbations and to distribution shift. We first prove that $p = \\Omega(dn)$ parameters can be sufficient for a class of neural networks to overfit the training data while guaranteeing robustness to adversarial perturbations. Then, we focus on spurious correlations learning in high-dimensional regression, studying the effect of the ridge regularization parameter in the proportional regime $n = \\Theta(d)$, and connecting it via an equivalence argument to the role of over-parameterization $p = \\Omega(n)$ in neural networks. We also investigate the architectural bias of attention-based networks, showing that they are sensitive to the replacement of individual words in an embedded sentence, allowing them to generalize on sentences where the contextual meaning depends on one or few words.\r\nFinally, we study differentially private optimization in high-dimensional regimes. We prove that standard private gradient methods do not suffer in the over-parameterized regime $p = \\Omega(n)$, challenging the current wisdom based on stability-derived generalization bounds. We then consider linear regression in the proportional regime $n = \\Theta(d)$, showing that standard private gradient descent can achieve optimal rates under appropriate hyper-parameter scaling, such as sufficiently small gradient clipping constants, whose role is still debated in practice." acknowledged_ssus: - _id: ScienComp acknowledgement: "This project was partially supported by the 2019 Lopez-Loreta prize,\r\nthe European Union (ERC, INF2\r\n, project number 101161364), the Austrian Science Fund\r\n(FWF) 10.55776/COE12, and a Google PhD fellowship in machine intelligence.

We introduce Causal Inference GWAS, a graphical approach that selects genetic instruments from summary statistics controlling for linkage and pleiotropy, accommodates rare variants and binary outcomes, distinguishes direct from indirect risk factors in high dimensions, and flags latent confounding. Applied to 9 risk factors, 4 metabolic disease outcomes, and 8.4M variants across 458,747 UK Biobank individuals, our method runs in 20 minutes, identifying only 696 genome-wide valid instruments. We replicate nearly all previously reported risk factor-outcome paths, but find that most are indistinguishable from unmeasured confounding. This suggests robust biobank causal inference will require longitudinal and family data to resolve temporal precedence from reverse causation. Our approach offers a principled first step toward screening genuine causal signal from phenotypic correlation in biobank data. acknowledged_ssus: - _id: ScienComp acknowledgement: "We thank Zoltan Kutalik andmembers of the Robinson group at ISTA for\r\ntheir comments, which improved this manuscript.

Our deep NIRSpec/\r\nG395M spectroscopy reveals unambiguous broad Balmer emission (FWHM = 2221 ± 20 km s\r\n−1\r\n), confirming a\r\nsuper-Eddington accreting black hole (BH) (λEdd = 2.7 ± 0.4) with a mass of\r\nlog(MBH/M ) = 7.55 ± 0.34,\r\nusing accretion-rate-corrected BH mass estimators. After subtracting the point source, we robustly detect stellar\r\nemission from the host galaxy across multiple NIRCam and MIRI filters. Our joint morphological-spectral\r\nanalysis yields a stellar mass of = ± * log(M /M ) 10.5 0.4\r\nand an intense star formation rate of\r\nSFR = 330 ± 97 M⊙ yr−1\r\n, confirming the host as a massive, dusty starburst galaxy. We find that GNz7q lies\r\non the local MBH–M* relation (MBH/M* ≃ 0.001) and is well positioned to evolve into the locus of massive Sloan\r\nDigital Sky Survey (SDSS) quasars with\r\nlog(MBH/M ) 9\r\nand M* ≈ 1011 M⊙ at z ∼ 6, owing to its remarkably\r\nrapid growth in both the BH and its host galaxy. This stands in stark contrast to many recently reported JWST\r\nactive galactic nucleus populations at similar redshifts, including the little red dots, whose weak or undetected star\r\nformation makes it difficult for them to grow into the massive galaxies hosting SDSS-like quasars. These results\r\nsuggest that GNz7q marks a rare, pivotal phase of early BH–galaxy coevolution, plausibly providing a crucial\r\ndirect pathway to the supermassive BH systems within the first billion years of the Universe." acknowledgement: "We are grateful to Jinyi Yang and Feige Wang for their insightful discussions about the broad-line fitting.

PS1 has been attributed roles in intracellular calcium homeostasis in the brain, as well as in the pancreatic beta cells, where it has been shown to be fundamental for the initial phase of glucose-induced insulin secretion. To gain mechanistic insight into beta cell autonomous function of PS1, we have examined various beta cell models and found that PS1 controls glycolytic flux of pancreatic beta cells by regulating sub-mitochondrial Ca2+ homeostasis. Transient knock down of PS1 yielded a glycolytic bottleneck at the step catalyzed by glyceraldehyde-3-phosphate dehydrogenase, resulting in defective glucose responsiveness. Moreover, we show that PS1 is needed for the preservation of beta cell identity, likely due to its role in glycolysis. Finally, we show that mouse islets from an in vivo model of AD mimic the defective glucose responsiveness seen in beta cells with transient PS1 knock down, while the identity loss and whole-body glucose homeostasis are not severely impacted, suggesting an adaptive response. Thus, the current work highlights beta cell autonomous role of PS1 and adds a layer of complexity in its impact on whole body metabolism. acknowledgement: We appreciate the technical assistance from Anna Schreilechner.

The ‘heavy-seed’ pathway eases the problem with the progenitors of these SMBHs having birth masses up to∼105 M\x03. Here, we investigate the possibility that a local dwarf galaxy, Leo I, harbours a heavy-seed descendant. Using Monte Carlo merger trees to generate the merger histories of 1000 dark matter haloes similar to the Milky Way (MW), we search for Leo- like satellite haloes and investigate the probability that the progenitors of these satellites formed a heavy seed. We derive the likelihood of such ‘heavy-seed survivors’ (HSSs) across various formation and survival criteria as well as Leo-similarity criteria. We find that the virial temperature for the onset of atomic cooling and rapid gas infall that yields heavy seeds, Tact , has the largest impact on HSS frequency. We find HSSs in a fraction 0.7 per cent, 18.1 per cent, and 96.5 per cent of MW-like haloes when Tact is set to 9000, 7000, and 5000 K, respectively. For the canonical atomic-cooling threshold ( Tact \x02 8000 K), the HSS fraction is\x03 1per cent , indicating that Leo I hosting a heavy-seed descendant is unlikely under well-motivated physical assumptions. Higher HSS fractions occur only under optimistic and currently unsubstantiated assumptions on Tact . Nevertheless, these results motivate future work that clarifies the possibility of heavy-seed BH formation in pristine haloes with nominal virial temperatures below 8000 K. This may motivate Leo I as a target for disentangling heavy seeds from other SMBH formation mechanisms." acknowledgement: We thank the anonymous reviewer for feedback that helped clarify this manuscript.

The imaging further reveals that the filaments are not smooth radial\r\nstreaks, but instead are composed of cascades of knots or clumps. The images in [O III] yield the first confirmation\r\nthat previously detected diffuse [O III] emission in fact originates from the same [S II] filaments. We measure a\r\nnebula center consistent with the position of the central star, indicating that the remnant has not received a large\r\ntransverse kick. The 3σ upper limit on the velocity of the stellar kick is ≲100 km s\r\n−1\r\n. Cross-sectional profiles of\r\nthe filaments in [S II] and [O III] show a central peak on top of a nebula background, the latter being likely due to\r\ndiffuse emission or unresolved filaments. The median [S II] width of 0.7 is slightly broader than the 0.50 seeing,\r\nproviding some evidence of partially resolved filaments and implying a characteristic knot diameter of ∼1016 cm.\r\nThe ≈1″ widths measured in [O III] are consistent with the poorer seeing of the oxygen images. The discovery of\r\nthis clumpy substructure provides a new observational constraint on models for the origin and evolution of the\r\nremarkable filamentary ejecta of Pa 30." acknowledgement: "We thank Jim Fuller, SR Kulkarni, David Charbonneau, Paul Duffell, Abigail Polin, Miranda Pikus, Tony Piro, Lars Bildsten, Eliot Quartert, and Rob Fesen for helpful discussions.

The resulting Clemens complex is more complicated than usual, and leads to particularly interesting effective cone constants, associated with exponentially many polytopes whose volumes appear in the expected formula. Like a jigsaw puzzle, these polytopes fit together to one large polytope. The volume of this polytope appears in the asymptotic formula that we obtain using the universal torsor method via o-minimal structures. acknowledgement: Open Access funding enabled and organized by Projekt DEAL.

Applying ac driving to the junction has proven to be a viable and less invasive way to extract information about the few lowest harmonics of the CPR, by locating the integer and fractional Shapiro steps in the \U0001D43C⁢\U0001D449-curve of the driven junction. Here, we present an alternative driving-based method that allows to extract the full harmonic content of a CPR in a relatively noninvasive way, by fitting the measured critical currents of the driven junction as a function of driving power. We test our method, both using numerical simulations and in experiments, and we show that it works accurately." acknowledgement: 'The authors thank Afonso Oliveira, Stefano Calcaterra, Daniel Chrastina, and Giovanni Isella for providing the Ge/SiGe heterostructure.
