Large floods drive changes in cause-specific mortality in the United States.

Flooding greatly endangers public health and is an urgent concern as rapid population growth in flood-prone regions and more extreme weather events will increase the number of people at risk. However, an exhaustive analysis of mortality following floods has not been conducted. Here we used 35.

Selection and colorimetric application of ssDNA aptamers against metamitron based on magnetic bead-SELEX.

Metamitron (MTM) is a typical and widely used triazine herbicide in agricultural production. Its moderate toxicity and high residue in the environment have deleterious impacts on human health. The establishment of a rapid and efficient MTM detection method is of great significance.

Selection and identification of a DNA aptamer for fluorescent detection of netilmicin.

Netilmicin (NET) is an antibiotic widely used in healthcare and agriculture, but it can accumulate in the environment to threat human health. Netilmicin (NET) is an antibiotic used for veterinary purposes, for human therapy and for agricultural purposes. Therefore, there is a need to develop high-sensitive measuring methods to detect NET.

[Study of the beam field of a new array ultrasound transducer].

This paper provides a new design of 12-element array ultrasound transducer. By modeling the beam field model of single element and array and comparing simulated and real ultrasound beam field test data, it can be demonstrated that 12-element array ultrasound transducer has a much better field performance than the 8-element transducer.

[Fetal ECG monitoring system based on MCU processing].

In order to monitor the fetus in labor, the signal characteristic from fetal scalp electrode is researched, An adaptation algorithm and a peak to peak detecting technology are adopted in signal processing, and an adaptation gain control method is used to eliminate disturber from base-line shift. A fetal ECG monitoring system is designed on the basis of C8051F020 MCU.
