Statistical estimation and nonlinear filtering in environmental pollution
Statistical Inference for Stochastic Processes, 2023 This paper studies a nonlinear filtering problem over an infinite time interval. The signal to be estimated is driven by a stochastic partial differential equation involves unknown parameters. Based on discrete observation, strongly consistent estimators of the parameters are derived at first.

Gut Microbiota in Tibetan Herdsmen Reflects the Degree of Urbanization
Frontiers in Microbiology, 2018 Urbanization is associated with shifts in human lifestyles, thus possibly influencing the diversity, interaction and assembly of gut microbiota. However, the question regarding how human gut microbiota adapts to varying lifestyles remains elusive.

Improving Speaker Recognition in Environmental Noise With Adaptive Filter
IEEE Access, 2022 Speaker recognition is challenging in real-world environments. Typically, studies approach noises only in an additive manner. However, real environments commonly present reverberating conditions that worsen speech processing. When not considering reverberation in the system modeling, the system may not be robust when applied to real-world conditions ...

Role of ion track filters in environmental surveillance
Environment International, 2001 Ion track filters (ITFs) are produced by physiochemical treatments to thin films of polymers and mica irradiated by heavy ions. These ITFs have many applications in the fields of science and technology. In the present investigation, the developed ITFs from polycarbonate films have been used to filter bacteria of various types in water.
