Abstract: In one example a pulse measurement system, comprises at least one sensor positioned to collect pulse information at three separate locations along a body segment, a controller communicatively coupled to the at least one sensor to receive the pulse information from the at least one sensor, and a display coupled to the controller to present at least one characteristic of the pulse information detected at the three separate locations. Other examples may be described.

Abstract: The TaNAC2 gene can promote uptake and utilization of nitrogen in a plant. A method for improving the uptake, transport and/or assimilation of nitrogen element in the plant includes: introducing a gene encoding a protein represented by SEQ ID NO:4 into a primary plant to obtain a transgenic plant. Compared to the primary plant, the uptake, transport and/or assimilation of the nitrogen element in the transgenic plant are improved. The method provides advantages in that: the TaNAC2 gene, as a nitrate nitrogen responsive regulatory factor, which can regulate the expression of a series of genes in nitrogen element uptake pathways of wheat, greatly promotes the study of the metabolism and utilization of the nitrogen element in a plant; and it is possible to improve the assimilation efficiency of nitrogen element by increasing the expression of TaNAC2, thereby reducing fertilizer application and increasing yield.
