At a redshift of z = 0 . 0868 , revealed by Keck Cosmic Web Imager spectroscopy of its faint star-forming host, it is the fourth-nearest example of its class to date. Rapid identification of the source in the Zwicky Transient Facility data stream permitted ultraviolet-through- optical observations to be obtained prior to peak, allowing the first determination of the peak bolometric luminosity ( 2 ×1045 erg s−1 ), maximum photospheric radius ( 1015 cm), and total radiated energy ( 1051 erg) of an 18cow-like object. We present results from a comprehensive multiwavelength observing campaign, including a far-ultraviolet spectrum from the Cosmic Origins Spectrograph on the Hubble Space Telescope and deep imaging extending > 100 d post-explosion from the Very Large Telescope, Hubble Space Telescope , Very Large Array, and Atacama Large Millimetre Array. We interpret the observations under a model in which a rapidly accreting central engine blows a fast ( ∼0.2 c ) wind into the surrounding medium and irradiates it with X-rays. The high Doppler velocities and intense ionization within this wind prevent identifiable spectroscopic features from appearing in the ejecta or in the surrounding circumstellar material. Weak H and He signatures do emerge in the spectra after 35 d in the form of double-peaked narrow lines. Each peak is individually narrow (full width δv ∼3000 km s−1 ) but the two components are separated by \x03v ∼6600 km s−1 , indicating stable structures of denser material, possibly representing streams of tidal ejecta or an ablated companion star." acknowledgement: "We thank Eliot Quataert, Luc Dessart, Ben Margalit, Ross Ferguson, Aaron Tohuvavohu, Brad Cenko, and Jamie Kennea for useful discussions.

Here, we show that exogenous IAA modulates growth in Chlorella sorokiniana, Chlorella variabilis, and Chlamydomonas reinhardtii in a concentration-dependent manner. Low IAA concentrations promoted growth by accelerating the onset of cell division without affecting cell size, whereas higher concentrations inhibited proliferation. Radiotracer assays showed that all three species take up and release IAA across the plasma membrane through a combination of passive diffusion and energy-dependent, saturable processes. Competition by excess unlabeled natural and synthetic auxins further supported the presence of carrier-mediated transport with broad substrate recognition. Phylogenetic analyses identified potential PIN-like auxin exporters in chlorophytes and other non-plant eukaryotes, and structural modeling supported conservation of the overall PIN fold and predicted auxin-binding residues. However, functional assays in Xenopus laevis oocytes, tobacco BY-2 cultured cells, and Arabidopsis thaliana did not support a role for these proteins in directional auxin export. Instead, non-plant PIN homologs localized predominantly to the endoplasmic reticulum and showed limited or no transport activity in heterologous systems. Together, these findings indicate that auxin responsiveness and basic cellular auxin transport predate canonical PIN-mediated directional auxin export, which appears to be a later innovation of the streptophyte lineage. acknowledged_ssus: - _id: Bio - _id: NanoFab acknowledgement: Research in the Friml group was supported by the European Research Council (ERC) under grant agreement No. 101142681 (CYNIPS), and by the Austrian Science Fund (FWF) through projects I 6123-B and P 37051-B.

The results obtained with our method frequently outperform screened Poisson surface reconstruction\r\n(PSR), GWN, and the pseudonormal method in terms of quality, and are at least on par with them on all of our examples.

This research analyses Iran's domestic air transport network (2018-2021) by developing annual Origin-Destination (OD) impedance matrices based on flight frequency. The methodology quantifies network connectivity, revealing a highly centralized structure dominated by core corridors like Tehran-Mashhad, which carried over 10,500 flights in 2019. The COVID-19 pandemic caused a severe disruption in 2020, with traffic on major routes falling by nearly half, followed by a partial recovery in 2021. Analysis shows core hubs rebounded faster than peripheral airports, widening accessibility gaps. Through origin-destination matrix processing, the system identifies high density air routes and analyses historical trends in airspace utilization. The impedance matrix, validated against data (R²=0.87), successfully maps the intense service on hub links and the high impedance of sparse peripheral routes. Then an interactive Web GIS platform was implemented for spatiotemporal analysis of air traffic density. acknowledgement: "We sincerely thank the Iranian Airports and Air Navigation\r\nCompany for sharing statistical data on flights from Iranian\r\nairports, separated by origin and destination, for this research." article_processing_charge: No author: - first_name: Masoumeh full_name: Eghbali Mardekheh, Masoumeh last_name: Eghbali Mardekheh - first_name: Meysam full_name: Argany, Meysam last_name: Argany - first_name: Farid full_name: Karimipour, Farid id: 2A2BCDC4-CF62-11E9-BE5E-3B1EE6697425 last_name: Karimipour orcid: 0000-0001-6746-4174 - first_name: Seyed Mohammad full_name: Sedghitabar, Seyed Mohammad last_name: Sedghitabar citation: ama: 'Eghbali Mardekheh M, Argany M, Karimipour F, Sedghitabar SM.

AP3 is generally believed to localize to clathrin-free, ARF1-positive, elongated carriers in cells, but the architecture of AP3-based coats was unknown. Using in vitro reconstitution and cryo–electron tomography, we demonstrate that AP3:ARF1 spontaneously remodels membranes containing cargo and the phosphoinositide PI(3,5)P\r\n 2\r\n \ into tubular structures coated in spiraling rows of AP3 arches and ARF1 dimers. Targeted point mutations disrupting critical AP3:ARF1 and AP3:AP3 lattice interfaces disrupt AP3 recruitment, carrier formation, and lysosomal cargo trafficking in cells. We propose that AP3 generates tubular carriers on endosomes by organizing ARF1 dimers into elongated membrane-deforming arrays while simultaneously selecting cargo. By demonstrating that AP3:ARF1 can generate carriers without using a clathrin lattice, we explain the clathrin independence of AP3-mediated trafficking." acknowledgement: "We thank P. Luzio, N.

However, the fundamental limits on the achievable speedup remain poorly understood. In this work, we establish the first “tight” lower bounds on the runtime of any deterministic speculative generation algorithm. This is achieved by drawing a parallel between the token generation process and branching random walks, which allows us to analyze the optimal draft tree selection problem. We prove, under basic assumptions, that the expected number of tokens successfully predicted per speculative iteration is bounded as \\mathbb{E}[X] ≤ (\U0001D707 + \U0001D707(2))log(B )/\U0001D7072 + O(1), where B is the verifier’s batch size, \U0001D707 is the expected entropy of the verifier’s output distribution, and \U0001D707(2) is this entropy’s second moment. This result provides new insights into the limits of parallel token generation, and could guide the design of future speculative decoding systems. Empirical evaluations on Llama models validate our theoretical predictions, confirming the tightness of our bounds in practical settings." article_processing_charge: No arxiv: 1 author: - first_name: Sergei full_name: Pankratov, Sergei id: f773bf05-72ef-11ef-b75a-a383d22f454b last_name: Pankratov - first_name: Dan-Adrian full_name: Alistarh, Dan-Adrian id: 4A899BFC-F248-11E8-B48F-1D18A9856A87 last_name: Alistarh orcid: 0000-0003-3650-940X citation: ama: 'Pankratov S, Alistarh D-A.

During zebrafish embryogenesis, the enveloping layer (EVL) – an epithelial monolayer covering the blastoderm – undergoes extensive spreading that is driven by pulling forces exerted at its margin and more than doubles its surface area. Yet whether and how the EVL actively regulates its tissue tension during this process remains unclear. Here, we show that the EVL maintains constant tissue tension while spreading, and that it achieves this by reducing apical cell contractility in response to the same pulling forces that drive its spreading. We identify a mechanosensitive pathway underlying this response, mediated by the scaffold/adaptor protein Kibra regulating the activity of atypical protein kinase C (aPKC) at the apical domain of EVL cells. Under low mechanical stretch, Kibra forms condensates at the base of actin-based apical projections, where it activates Myosin II to increase apical contractility through aPKC downregulation. As mechanical stretch increases, apical projections disassemble, Kibra condensates dissolve, and aPKC activity rises. Elevated aPKC activity in turn reduces apical contractility by reducing Myosin II activity, thereby maintaining constant tissue tension despite increased mechanical stretch. Together, these findings reveal a mechanosensitive mechanism that enables robust adaptation of tissue tension to changing mechanical stretch, ensuring efficient tissue spreading and morphogenesis. acknowledged_ssus: - _id: Bio - _id: LifeSc - _id: EM-Fac acknowledgement: We thank all members of the Heisenberg group for discussion and feedback on the manuscript, and the Imaging and Optics Facility, the Life Science Support Facility and the Electron Microscopy Facility of the Institute of Science and Technology Austria (ISTA) for their continued support.

Suppose a 3-graph has the property that the link of every vertex has\r\nan ε-homogeneous partition of size poly(1/ε). Does this guarantee that the 3-graph also has a small\r\nhomogeneous partition? Terry and Wolf proved that such a 3-graph has an ε-homogeneous partition\r\nof size given by a wowzer-type function. Terry recently improved this to a double exponential bound,\r\nand conjectured that this bound is tight. Our first result in this paper disproves this conjecture by\r\ngiving an improved (single) exponential bound, which is best possible. We further obtain an analogous\r\nresult for k-graphs of all uniformities k 3. The above problem is part of a much broader programme,\r\nwhich seeks to understand the conditions under which a (hyper)graph has small ε-regular partitions.\r\nWhile this problem is fairly well understood for graphs, the situation is (as always) much more\r\ninvolved already for 3-graphs. For example, it is natural to ask if one can strengthen our first result\r\nby only requiring each link to have ε-regular partitions of size poly(1/ε). Our second result shows that\r\nsurprisingly the answer is “no”, namely, a 3-graph might only have regular partitions of tower-type size,\r\neven though the link of every vertex has an ε-regular partition of polynomial size." article_number: rnag018 article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Lior full_name: Gishboliner, Lior last_name: Gishboliner - first_name: Asaf full_name: Shapira, Asaf last_name: Shapira - first_name: Yuval full_name: Wigderson, Yuval id: 2d0023a0-1567-11f0-833d-d5c1e476d4b5 last_name: Wigderson citation: ama: Gishboliner L, Shapira A, Wigderson Y.

De plus, je discute le travail suivant de Balister, Bollobás, Campos, Griffiths, Hurley, Morris, Sahasrabudhe, et Tiba, qui ont donné une preuve alternative et plus conceptuelle." article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Yuval full_name: Wigderson, Yuval id: 2d0023a0-1567-11f0-833d-d5c1e476d4b5 last_name: Wigderson citation: ama: 'Wigderson Y.

Constriction of these spaces (e.g., arterial occlusion, fibrosis) highlights their importance, making their mimicry essential in tissue engineering (TE). This review examines four key strategies for introducing porosity into hydrogels across multiple length scales: templating, microgels, phase separation, and 3D printing. The first three methods enable the engineering of physiological environments at the nano‐ to micro‐scale, mimicking tissue‐ and extracellular matrix (ECM)‐level spaces. Templating involves embedding and removal of gas, liquid, or solid phases, leaving behind pores. Microgel annealing generates inherent interstitial voids. Liquid–liquid phase separation (LLPS) creates biphasic networks reminiscent of native ECM. The fourth approach, extrusion‐ and light‐based 3D printing techniques, enables the fabrication of larger‐scale spaces, such as luminal structures (e.g., vasculature, airways, and ducts). Combining these methods enables the creation of hierarchical architectures from the nano‐ to centimeter scale. The review also highlights Filamented Light (FLight) technology, which creates internal microstructural voids relevant to anisotropic tissues. This review offers insights into current methods and their convergence for generating biomimetic void spaces to meet the physiological demands of cells, tissues, and organs.' article_number: e07385 article_processing_charge: No article_type: original author: - first_name: Anna full_name: Puiggalí‐Jou, Anna last_name: Puiggalí‐Jou - first_name: Isabel B. full_name: Hui, Isabel B. last_name: Hui - first_name: Carla full_name: Fernández-Rico, Carla id: 492def71-6250-11f0-b278-d41dbd241b62 last_name: Fernández-Rico - first_name: Marcy full_name: Zenobi‐Wong, Marcy last_name: Zenobi‐Wong citation: ama: 'Puiggalí‐Jou A, Hui IB, Fernández-Rico C, Zenobi‐Wong M.

At low supersaturation, network elasticity stabilizes a uniform mixture, but beyond a critical threshold, metastable microphase-separated domains emerge. While previous theories have focused on describing qualitative features about the size and morphology of these domains, they do not make quantitative predictions about EMPS phase diagrams. In this work, we extend Flory–Huggins theory to quantitatively capture EMPS phase diagrams by incorporating strain-stiffening effects. This model requires no fitting parameters and relies solely on independently measured solubility parameters and large-deformation mechanical responses. Our results confirm that strain-stiffening enables metastable microphase separation within the swelling equilibrium state and reveal why the microstructures can range from discrete droplets to bicontinuous networks. This works highlights the critical role of nonlinear elasticity in controlling phase-separated morphologies in polymer gels. article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Carla full_name: Fernández-Rico, Carla id: 492def71-6250-11f0-b278-d41dbd241b62 last_name: Fernández-Rico - first_name: Robert W. full_name: Style, Robert W. last_name: Style - first_name: Stefanie full_name: Heyden, Stefanie last_name: Heyden - first_name: Shichen full_name: Wang, Shichen last_name: Wang - first_name: Peter D. full_name: Olmsted, Peter D. last_name: Olmsted - first_name: Eric R. full_name: Dufresne, Eric R. last_name: Dufresne citation: ama: Fernández-Rico C, Style RW, Heyden S, Wang S, Olmsted PD, Dufresne ER.
