Fibronectin1‐Expressing Subicular Circuits Selectively Govern the Retrieval of Novel Object Recognition

Advanced Science, EarlyView.
Fibronectin 1 (FN1)‐expressing subicular subpopulations encode novel object preference and selectively govern retrieval of novel object recognition (NOR) via affecting excitability of entorhinal‐projecting circuit through large conductance Ca2+‐activated potassium (BK) channel. ABSTRACT Novel object recognition (NOR), referring to the cognitive ability

Synchrotron XRF Imaging Reveals Manganese Accumulation in the Golgi and Post‐Synapses of Neurons and Enhanced Uptake in Astrocytes

Advanced Science, EarlyView.
Despite widespread exposure, the mechanisms of manganese neurotoxicity remain poorly understood. Using correlative cryogenic fluorescence and synchrotron X‐ray fluorescence imaging techniques, we show that the Golgi apparatus is the primary accumulation site for manganese in both neurons and astrocytes, and that manganese targets the neuronal ...

Ultrafast GaAs microwave PIN diode

Electronics Letters, 1983
This letter describes what is believed to be the first successful realisation of GaAs PIN diodes. The vertical structure was grown on an n+ substrate by MOCVD of a 2 μm, 1015 cm−3 unintentionally doped n− layer followed by a 0.3 μm, 4×1019 cm−3 Zn doped p+ layer. The isolation and insertion loss of a single shunt-mounted device are typically −27 dB and

Nanoscale Spatial Organization of ARC High‐ and Low‐Order Assemblies at Excitatory Synapses

Advanced Science, EarlyView.
ARC (Activity‐Regulated Cytoskeleton‐Associated protein) mediates synaptic plasticity by forming nanoscale assemblies in neurons. Using super‐resolution microscopy and time‐resolved anisotropy with targeted tagging, the study reveals low‐order ARC assemblies at synapses colocalizing with AMPARs, semi‐circular structures at endocytic zones, and 60–80 nm

Random Time‐Space Coding Metasurfaces for Spatial Control of the Temporal Statistics of Electromagnetic Fields

Advanced Science, EarlyView.
A probabilistic framework based on random time‐space coding metasurfaces enables control of the spatial distribution of electromagnetic fields temporal statistics. By tailoring the marginal and joint distributions of random codes, electromagnetic fields with desired mean and variance patterns are realized, enabling simultaneous transmission and jamming.
