Adaptive Recognition of Bioacoustic Signals in Smart Aquaculture Engineering Based on r-Sigmoid and Higher-Order Cumulants.

In recent years, interest in aquaculture acoustic signal has risen since the development of precision agriculture technology. Underwater acoustic signals are known to be noisy, especially as they are inevitably mixed with a large amount of environmental background noise, causing severe interference in the extraction of signal features and the revelation of internal laws. Furthermore, interference adds a considerable burden on the transmission, storage, and processing of data.

Tracking pesticide exposure to operating workers for risk assessment in seed coating with tebuconazole and carbofuran.

Background: Coating seed with pesticides is an effective way to control plant pests, however, factory-based coating processes may carry a potential risk to operational workers of chemical exposure. To study the risk, carbofuran and tebuconazole were used to coat corn seed and their subsequent distribution on the bodies of workers was measured at manufacturers XFS and LS (Shanxi, China). Clothing was collected from workers during operations and analyzed using high-performance liquid chromatography.

Diagnostic value of heat shock protein 90 and squamous cell carcinoma antigen in detection of cervical cancer.

Objective: To ascertain plasma levels of heat shock protein 90α (HSP90α) and squamous cell carcinoma antigen (SCC-Ag) and their diagnostic potential in cervical cancer.

Methods: In a cross-sectional study, patients’ cervical tissue samples were screened for high risk (HR) human papilloma virus (HPV) DNA and underwent a thinprep-liquid based cytology test (TCT). Plasma samples were analysed by enzyme-linked immunosorbent assay (ELISA) for HSP90 α and SCC-Ag levels.
