In recent years, as China has entered the fast lane of economic development, air pollution in many places is more serious. As the main source of pollution, large particulate matter has caused haze in many places, which has also attracted the attention of the state and relevant researchers. The government also began to control the air pollution. Wit...

The minimum mean-square error (MMSE)-based noise PSD estimators have been used widely for speech enhancement. However, the MMSE noise PSD estimators assume that the noise signal changes at a slower rate than the speech signal— which lacks the ability to track the highly non-stationary noise sources. Moreover, the performance of the MMSE-based noise...

PM2.5 lasts a long time in the air, and it will disperse with the wind and direction. Therefore, PM2.5 will not only pollute the local air to a certain extent, but also pollute the surrounding air with the change of wind and direction. Experiments show that the concentration of PM2.5 in the city is not only related to the spatial location of the ci...

In fish consumption advisories pertaining to Hg, grouper species in the family Serranidae are often lumped together and labeled generically as Grouper. However, grouper species vary considerably in growth rate, maximum age, and maximum size. This study examined the variability of Hg concentrations and bioaccumulation rates (increase of Hg concentra...

Hydraulic conductivity is a basic property of rocks and soil, and its estimation varies as a function of the scale and purpose of the study. This work combines geomorphological analysis, geological data, and groundwater investigations from literature to assess large-scale anisotropies in hydraulic conductivity in the North China Plain. The study ar...

We investigate how force chains in a granular packing influence and change during a tunnel excavation process. A two-dimensional (2D) frictional cohensionless packing is considered under gravity and a set of contiguous particles are removed in the interior. Using discrete element simulations on realistic non-spherical soil grains, we investigate th...

Screening and follow-up of interstitial lung disease associated with rheumatoid arthritis (RA-ILD) is a challenge in clinical practice. In fact, the majority of RA-ILD patients are asymptomatic and optimal tools for early screening and regular follow-up are lacking. Furthermore, some patients may remain oligosymptomatic despite significant radiolog...

AbstractIn the past decade, advances in electronics technology have made larger imaging sensors available to the experimental fluid mechanics community. These advancements have enabled the measurement of 2-component 2-dimensional (2C–2D) velocity fields using particle image velocimetry (PIV) with much higher spatial resolution than previously possi...

Phthalocyanines are of a broad interest in photovoltaic applications. In this study, films of titanium-phthalocyanine-chloride (TiPcCl2) were prepared by the thermal evaporation method. The molecular structure was studied by a Raman spectrometer, showing a match between the spectra of the powder and the prepared films. The films' surface was examin...
