摘要：Many natural motor skills, such as speaking or locomotion, are acquired through a process of trial-and-error learning over the course of development. It has long been hypothesized, motivated by observations in artificial learning experiments, that dopamine has a crucial role in this process. Dopamine in the basal ganglia is thought to guide reward-based trial-and-error learning by encoding reward prediction errors1, decreasing after worse-than-predicted reward outcomes and increasing after bet...

摘要：Ionotropic glutamate receptors (iGluRs) are tetrameric ligand-gated ion channels that mediate most excitatory neurotransmission1. iGluRs are gated by glutamate, where on glutamate binding, they open their ion channels to enable cation influx into postsynaptic neurons, initiating signal transduction1,2. The structural mechanics of how glutamate gating occurs in full-length iGluRs is not well understood. Here, using the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid subtype iGluR (AMPA...

摘要：In the future, monsoon rainfall over densely populated South Asia is expected to increase, even as monsoon circulation weakens1, 2-3. By contrast, past warm intervals were marked by both increased rainfall and a strengthening of monsoon circulation4, 5-6, posing a challenge to understanding the response of the South Asian summer monsoon to warming. Here we show consistent South Asian summer monsoon changes in the mid-Pliocene, Last Interglacial, mid-Holocene and future scenarios, characterized...

摘要：Hilbert space dimension is a key resource for quantum information processing(1,2). Not only is a large overall Hilbert space an essential requirement for quantum error correction, but a large local Hilbert space can also be advantageous for realizing gates and algorithms more efficiently(3, 4, 5, 6-7). As a result, there has been considerable experimental effort in recent years to develop quantum computing platforms using qudits (d-dimensional quantum systems with d > 2) as the fundamental uni...
