Transcranial magnetic stimulation over right intraparietal sulcus improves selective attention for feature discriminating.

Background: Previous studies have confirmed the coordinated control of attentional processes by the frontal and parietal lobes. However, the function of the intraparietal sulcus (IPS) in the attention system remains unclear. In this study, we measured transcranial magnetic stimulation (TMS)-evoked event-related potentials (ERPs) to determine the extent to which the right intraparietal sulcus (rIPS) is involved in attentional processing.

Influence of portal excavation of shallow-buried bias tunnel on stability of soil‒rock bedding slope: a case study of Moziping tunnel.

The excavation of tunnel portals in shallowly buried bias tunnels in mountainous areas is highly prone to causing instability of the soil‒rock bedding slopes at portals, which threatens project safety. This paper uses the Moziping tunnel outlet section as the engineering background. A research approach that combines theoretical analysis, numerical simulation, and field monitoring is adopted to systematically investigate the impact mechanism of tunnel excavation on the stability of soil‒rock bedding slopes.

A mini review of the recent progress of electrode materials for low-temperature solid oxide fuel cells.

Lowering the operating temperature (450-650 °C) of solid oxide fuel cells (SOFCs) faces the intrinsic challenge of sluggish electrode reaction kinetics in the low temperature (LT) range. To accelerate the electrode reaction rate, many efforts have been put into the optimization of electrode composition and morphology. In this review, we have summarized recent developments of LT-SOFC electrodes, including anode and cathode materials.

Portable and Battery-Powered PCR Device for DNA Amplification and Fluorescence Detection.

Polymerase chain reaction (PCR) is a technique for nucleic acid amplification, which has been widely used in molecular biology. Owing to the limitations such as large size, high power consumption, and complicated operation, PCR is only used in hospitals or research institutions. To meet the requirements of portable applications, we developed a fast, battery-powered, portable device for PCR amplification and end-point detection.
