The shape of animal cells is controlled by their surface, which comprises the cell cortex, a peripheral actin network, tethered to the plasma membrane by membrane-to-cortex attachment proteins. Changes in cortical components have long been considered to dominate the regulation of forces and mechanical properties at the cell surface and drive morphogenesis [...]

Protein kinases integrate cellular signals through complex phosphorylation cascades, yet resolving how chemical perturbations trigger and modulate these cascades in therapeutic targets remains a major challenge. Here, we dissect adenosine 5′-monophosphate–activated protein kinase (AMPK) proteoforms during activation through controlled biochemical reactions with a hybrid mass spectrometry (MS) approach integrating bottom-up MS for site-specific kinetics with top-down proteoform characterization [...]

This paper presents differential cross-section measurements of events containing a charged lepton, missing transverse momentum, two b-jets, and two light jets, consistent with the $ {W}^{+}{W}^{-}b\overline{b} $ final state. The analysis is based on 140 fb$^{−1}$ of proton-proton collision data at $ \sqrt{s}=13 $ TeV recorded with the ATLAS detector during Run 2 of the Large Hadron Collider (2015–2018) [...]

This paper presents two searches for the electroweak production of higgsinos with compressed mass spectra using 140 fb$^{−1}$ of $ \sqrt{s}=13 $ TeV proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider. Events are required to feature an energetic jet, large missing transverse momentum, and at least one low-momentum charged particle that serves as a candidate higgsino decay product [...]

Synthesis of new topological quantum materials is necessary as it enables a fascinating platform for studying chemical bonding, crystal structure, and exotic transport phenomena in crystalline solids. The robust charge transport arising from the topologically protected non-trivial electronic states gives rise to intriguing quantum properties. [...]

Sparse representations are often expected to make models smaller and also reduce inference cost. For Fourier Neural Operators (FNOs), these objectives are not equivalent or do not always align: removing parts of the learned operator can leave the underlying transforms and dense computations unchanged, while changing the grid on which the model is evaluated can introduce overhead of its own. [...]

We demonstrate precise control of exchange bias (EB) in the Nd$_{2−x}$Sr$_x$CoMnO$_{6−δ}$(0 $≤ x ≤$ 1) double-perovskite series through Sr$^{2+}$-induced hole doping, revealing a remarkable transition between normal and inverse EB. Using neutron powder diffraction and x-ray absorption spectroscopy, we uncover a structural evolution from a 𝐵-site-ordered monoclinic (𝑃⁢2$_1$/𝑛) to a disordered rhombohedral (𝑅⁢$\bar{3}$𝑐) phase with increasing 𝑥 [...]

Despite the Standard Model's ability to describe collider data from all experiments conducted around the world, several questions about the history of the Universe, including the hierarchy problem, the baryon asymmetry, and the dark matter density, remain open. To address these unresolved issues, the particle physics community agrees on the need to construct a next-generation collider that could probe the Standard Model with higher accuracy and potentially reveal deviations from the predictions of this fundamental theory. [...]

A measurement of correction factors for the hadronic jet energy scale and resolution in the ATLAS detector is presented. These correction factors account for differences between simulated and observed data. [...]

A search for final states characterised by at least one isolated high transverse-momentum photon, jets and large missing transverse momentum is presented. Such a final state might occur in gauge-mediated supersymmetric models where a pair of binos and higgsinos mix to form neutralinos, one of which decays into a photon plus a gravitino while the other decays into a Higgs boson, a Z boson or a photon, plus a gravitino [...]
