Machine learning(ML) has been widely applied to the upper layers of wireless communication systems for various purposes, such as deployment of cognitive radio and communication network. However, its application to the physical layer is hampered by sophisticated channel environments and limited learning ability of conventional ML algorithms. Deep learning(DL) has been recently applied for many fields, such as computer vision and natural language processing, given its expressive capacity and convenient optimization capability. The potential application of DL to the physical layer has also been increasingly recognized because of the new features for future communications, such as complex scenarios with unknown channel models, high speed and accurate processing requirements; these features challenge conventional communication theories. This paper presents a comprehensive overview of the emerging studies on DL-based physical layer processing, including leveraging DL to redesign a module of the conventional communication system(for modulation recognition, channel decoding, and detection) and replace the communication system with a radically new architecture based on an autoencoder. These DL-based methods show promising performance improvements but have certain limitations, such as lack of solid analytical tools and use of architectures that are specifically designed for communication and implementation research, thereby motivating future research in this field.

Glycosylated volatiles are considered as hidden aroma precursors that affect fruit flavor and are involved in plant defense response. Several uridine-diphosphate(UDP)-glycosyltransferase(UGT) members related to the glycosylation of volatiles have been identified from grapevine berries. Although grapevine leaves produced much higher levels of glycosylated volatiles than berries, UGTs responsible for the production of glycosylated volatiles in leaves have not yet been identified. Here, eight novel UGT genes were cloned, among these four members that belong to UGT85A family(named UGT85A24, UGT85A25, UGT85A26, and UGT85A27) were localized in the cytoplasm and their recombinant proteins showed activity toward volatiles detected in grapevine, with geraniol as the preferred substrate in vitro. Two UGT genes with 98.1% homology differ in R/S-linalool selection. The UGT85A26-catalyzed substrate showed enrichment in S-linalool, whereas UGT85A27 showed a strong preference for R-linalool. UGT85A24 and UGT85A25 were expressed mainly in berries, and UGT85A26 and UGT85A27 were expressed predominantly in grapevine mature leaves and correlated with the highest content of glycosylated volatiles in the mature leaves. Methyl jasmonate(MeJA) induced the expression of UGT85A26 and UGT85A27 as well as the production of linalyl-β-glucoside, citronellyl-β-glucoside and phenethyl-β-glucoside. Transient overexpression of UGT85A26 and UGT85A27 in tobacco leaves led to the accumulation of linalyl-β-glucoside and an increase in citronellyl-β-glucoside in vivo. These results indicate that the expression of UGT85A26 and UGT85A27 is a major regulator affecting the content of glycosylated volatiles in grapevine.

In order to investigate the permeability of porous media,it is necessary to figure out the property of wave propagation in this medium. The authors calculated the full waveforms and the 2-dimensional spectrum of fluid saturated porous media,analyzed the wave propagation characteristics of different permeable stratums. From the theoretical acoustic pressure waveform received at the well-axis and the 2-D spectrum it is revealed that longitudinal-,transverse-,Stoneley-,pseudo-Rayleigh-,longitudinal mode-and transverse mode waves are different in characters in various permeable strata. Stoneley wave is sensitive to the change of permeability,and its frequency range and amplitude attenuation are influenced by permeability.

The car-following models are the research basis of traffic flow theory and microscopic traffic simulation. Among the previous work, the theory-driven models are dominant, while the data-driven ones are relatively rare. In recent years, the related technologies of Intelligent Transportation System (ITS) re- presented by the Vehicles to Everything (V2X) technology have been developing rapidly. Utilizing the related technologies of ITS, the large-scale vehicle microscopic trajectory data with high quality can be acquired, which provides the research foundation for modeling the car-following behavior based on the data-driven methods. According to this point, a data-driven car-following model based on the Random Forest (RF) method was constructed in this work, and the Next Generation Simulation (NGSIM) dataset was used to calibrate and train the constructed model. The Artificial Neural Network (ANN) model, GM model, and Full Velocity Difference (FVD) model are em- ployed to comparatively verify the proposed model. The research results suggest that the model proposed in this work can accurately describe the car- following behavior with better performance under multiple performance indicators.
