▲ Abstract： Here we demonstrate the realization of a new platform consisting of large-scale 2D arrays of sub-nanometre precision-engineered atom-based quantum dots (15,自然周论000 sites) to simulate strongly interacting, low-temperature physics. By observing a metal–insulator (MI) transition on a 2D square lattice of atom-based quantum dots, we demonstrate independent and precise control of the on-site interaction U and tunnelling t. Magneto-transport measurements further indicate the formation of an insulating state driven by Mott–Hubbard/Anderson physics and promising signatures of correlated electron physics. These precision-engineered analogue quantum simulators provide a unique platform to simulate quantum materials on arbitrary 2D lattices and to explore many unanswered questions in the formation of quantum magnetism, interacting topological quantum matter and unconventional superconductivity.

▲ Abstract： Here, to address this gap, I explored influences on the effect sizes of vegetation spillovers from a candidate 12,513 Australian protected areas, defining spillovers as the difference in vegetation outside a protected area that occurs as a consequence of the existence of the protected area. In 2020, 71% (2,189) out of the 3,063 protected areas for which full analysis was possible had a positive spillover effect of 0.1 or greater on at least 1 of 10 vegetation cover classes. Many protected area types were significant predictors of spillover magnitude. The covariance explained by protected area type with local and contextual variables was 14%, suggesting that internal management moderates adjacent locations. These findings highlight the potential to include spillover effects explicitly in global policy frameworks and suggest a pathway to an empirical basis for monitoring and accounting schemes that support biodiversity conservation and ecosystem service provision adjacent to protected areas.

▲ Abstract： Here we report a SW ladder filter architecture requiring only a single external magnetic bias, which is enabled by modern micromachining fabrication methods capable of wafer-scale production. The filters developed in this work demonstrate loss as low as 2.54?dB, bandwidths up to 663?MHz, centre-frequency tuning over several octaves from 7.08 to 21.6?GHz and high linearity with an input-referred third-order intercept point of more than 11?dBm in the passband. The operation of the filter is also experimentally demonstrated in a frequency-tunable radio system.

▲ Abstract： Here we report that β3-adrenergic activation of adipocytes induces a transient and depot-specific infiltration of neutrophils into white adipose tissue (WAT), particularly in lipid-rich visceral WAT. Neutrophil recruitment requires the stimulation of both lipolysis and p38 MAPK in adipocytes, and is mediated by the secretion of leukotriene B4. Recruited neutrophils undergo activation in situ, and locally secrete IL-1β, which suppresses lipolysis and limits excessive energy loss. Neutrophil depletion or blockade of IL-1β production increases lipolysis, leading to reduced WAT mass after repeated β3-adrenergic stimulation. Together, these findings reveal a role of neutrophil-derived IL-1β in preserving lipid stores during metabolic stress, highlighting a physiological function of innate immune cells in limiting lipid loss and maintaining energy homeostasis.
