Changes in resting-state brain function in chronic alcohol users based on degree centrality.

ObjectiveTo examine the effects of chronic alcohol consumption on brain functional connectivity using resting-state functional magnetic resonance imaging and degree centrality analysis.MethodsThis was a cross-sectional study, with participants including 23 light-to-moderate drinkers, 25 heavy drinkers, and 29 healthy controls aged 40-60 years. Degree centrality analysis was used to compare brain function differences among groups, and the relationships between degree centrality values, cognitive scores, and drinking behaviors were explored.

3D Printing of TPU-Liquid Metal Composite Inks for the Preparation of Flexible Sensing Electronics.

Direct 3D printing of liquid metal is difficult to form and easy to destroy. In this paper, we developed a 3D printed composite material consisting of a thermoplastic polyurethane (TPU) matrix and liquid metal (LM) dispersed droplets, and introduced the method for realizing 3D printed devices with this composite material: First, the LM is added to 10~50wt %TPU at 190~200 °C through ultrasonic blending to prepare blended ink. After solid cooling, the LM-TPU composite fiber with a diameter of 600 μm was prepared by Wellzoom desktop extruder at 190 °C at an extrusion speed of 400 mm/min.
