Foodborne pathogens like Listeria monocytogenes can cause various illnesses and pose a serious threat to public health. They produce species-specific microbial volatile organic compounds, i.e., the biomarkers, making it possible indirectly measure contamination in foodstuff. Herein, highly ordered mesoporous tungsten oxides with high surface areas tunable pores have been synthesized used as sensing materials achieve an exceptionally sensitive selective detection of trace monocytogenes. The...
A fuzzy logic and neuro-fuzzy system for classification of hydrometeor type based on polarimetric radar measurements is described in this paper. The implemented by using a neural network, where the used to infer type, network learning algorithm automatic adjustment parameters sets according prior knowledge. Five measurements, namely, horizontal reflectivity (ZH), differential (ZDR), propagation phase shift (KDP), correlation coefficient [ρHV(0)], linear depolarization ratio (LDR),...
High-sensitive measurement of radio-frequency (RF) electric field is available via the electromagnetically induced transparency (EIT) effect Rydberg atom at room-temperature, which has been developed to be a promising atomic RF receiver.

We present a theoretical and experimental investigation of the improvement determination sensitivity Rydberg atom-based microwave RF sensor. An optical Bloch equation has been set up based on configuration that two-color cascading lasers exciting atom to highly state coupling this its adjacent neighbor. The numerical simulation shows atomic sensor is correlated with amplitude strengths applied two itself. It also depends frequency detuning laser, which induces an asymmetrically splitting....
Electron emission from the single-electron capture with simultaneous single ionization in 30 keV/u He${}^{2+}$ on argon was investigated using a reaction microscope, providing electron energy spectra and momentum distributions. Intensive peaks for electrons near-zero kinetic energies have been observed. It is demonstrated that mechanisms contributing to include direct transfer (DTI), double-electron autoionization (DECA), (SECA) of target. Comparison resonance shows Ar${}^{+}$ ions SECA...
In China, filial piety, which usually refers to showing respect and obedience parents, has exerted an important effect in the relationship between work stress turnover intention. However, mechanism behind this is still unclear. To address gap existing literature, we developed tested a moderated mediation model of that shares with job satisfaction accordance dual piety stress-moderation model, our hypothesized predicted mediating on intention would be by reciprocal (RFP) authoritarian (AFP)....
Rock electrical parameters of tight gas sandstone show large variations in the T2 member Dingbei Block, Ordos Basin, China. Applying same rock water saturation calculations would lead to errors. Based on casting thin sections, x-ray diffraction, scanning electron microscopy (SEM), cathode luminescence, porosity and permeability, image analysis, high-pressure mercury intrusion/withdrawal method, identification diagenetic facies are first conducted, then their pore structure relationship with...
A microwave electric field sensing has been set up based on a three-color electromagnetically induced absorption in rubidium vapor cell via cascading transitions.
