Highly sensitive volumetric single-molecule imaging.

Volumetric subcellular imaging has long been essential for studying structures and dynamics in cells and tissues. However, due to limited imaging speed and depth of field, it has been challenging to perform live-cell imaging and single-particle tracking. Here we report a 2.

Construction of sulfur-containing -vinylimides: -addition of imides to propargyl sulfonium salts.

An -addition reaction between imides and propargyl sulfonium salts was developed to afford sulfur-containing -vinylimides with moderate to excellent yields. Under the activation of NaOAc·3HO, imides could undergo deprotonation and propargyl sulfonium salts could isomerize to allenic sulfonium salts. The -nucleophilic attack initiates the reaction and gives the desired products.

Characteristics of brain connectivity during verbal fluency test: Convolutional neural network for functional near-infrared spectroscopy analysis.

Human connectome describes the complicated connection matrix of nervous system among human brain. It also possesses high potential of assisting doctors to monitor the brain injuries and recoveries in patients. In order to unravel the enigma of neuron connections and functions, previous research has strived to dig out the relations between neurons and brain regions.
