Knowledge Augmented Relation Inference for Group Activity Recognition

arXiv (Cornell University) (2023)

Xianglong Lang Zhuming Wang Zun Li Meng Tian Ge Shi

Most existing group activity recognition methods construct spatial-temporal relations merely based on visual representation. Some methods introduce extra knowledge, such as action labels, to build semantic relations and use them to refine the visual presentation. However, the knowledge they explored just stay at the semantic-level, which is insufficient for pursing notable accuracy. In this paper, we propose to exploit knowledge concretization for the group activity recognition, and develop a novel Knowledge Augmented Relation Inference framework that can effectively use the concretized knowledge to improve the individual representations. Specifically, the framework consists of a Visual Representation Module to extract individual appearance features, a Knowledge Augmented Semantic Relation Module explore semantic representations of individual actions, and a Knowledge-Semantic-Visual Interaction Module aims to integrate visual and semantic information by the knowledge. Benefiting from these modules, the proposed framework can utilize knowledge to enhance the relation inference process and the individual representations, thus improving the performance of group activity recognition. Experimental results on two public datasets show that the proposed framework achieves competitive performance compared with state-of-the-art methods.

Subpicogram Determination of Melamine in Milk Products Using a Luminol−Myoglobin Chemiluminescence System

Journal of Agricultural and Food Chemistry (2009)

Zhuming Wang Donghua Chen Xin Gao Zhenghua Song

A sensitive chemiluminescence method based on a luminol−myoglobin system is proposed for the determination of melamine in milk products. It was found that the mixed solutions of melamine and myoglobin could react to form a complex on line, which could greatly inhibit the chemiluminescence intensity generated from the reaction between luminol and myoglobin. The decrease in chemiluminescence intensity was proportional to the concentration of melamine, giving a calibration graph linear over the concentration from 10 pg mL−1 to 50 ng mL−1 (R2 = 0.9988) with a detection limit of 3 pg mL−1 (3σ). At a flow rate of 2.0 mL min−1, one analysis cycle, including sampling and washing, could be accomplished in 20 s with a relative standard deviation of <4.0%. The proposed method was applied successfully to the determination of melamine in milk products, and the recovery was from 93.4 to 106.5%. The possible mechanism of luminol−myoglobin−melamine reaction is given.

Exploiting Non-uniform Inherent Cues to Improve Presentation Attack Detection

Yaowen Xu Zhuming Wang Hu Han Lifang Wu Yongluo Liu

Face anti-spoofing plays a vital role in face recognition systems. The existed deep learning approaches have effectively improved the performance of presentation attack detection (PAD). However, they learn a uniform feature for different types of presentation attacks, which ignore the diversity of the inherent cues presented in different spoofing types. As a result, they can not effectively represent the intrinsic difference between different spoof faces and live faces, and the performance drops on the cross-domain databases. In this paper, we introduce the inherent cues of different spoofing types by non-uniform learning as complements to uniform features. Two lightweight sub-networks are designed to learn inherent motion patterns from photo attacks and the inherent texture cues from video attacks. Furthermore, an element-wise weighting fusion strategy is proposed to integrate the non-uniform inherent cues and uniform features. Extensive experiments on four public databases demonstrate that our approach outperforms the state-of-the-art methods and achieves a superior performance of 3.7% ACER in the cross-domain Protocol 4 of the Oulu-NPU database.

A valuable way for understanding the relationships between lysozyme and cephalosporin analogues by flow injection chemiluminescence

The Analyst (2010)

Zhuming Wang Zhenghua Song

The photochemical reaction mechanism of lysozyme with cephalosporin analogues was investigated with luminol used as a luminescence probe by flow injection chemiluminescence. It was found that Glu35 and Asp52 of lysozyme accelerated the rate of excited 3-aminophthalate electrons transferring and enhanced the chemiluminescence signal of luminol, producing steady-state chemiluminescence in the flow injection system with relative standard deviations less than 3.0%. It was also found that cephalosporin analogues could enter into the site of Trp62 in lysozyme forming 1 : 1 complex which leads to a conformational change of lysozyme, giving the effect of chemiluminescence quenching from luminol–lysozyme. Based on the photochemical behavior of luminol/lysozyme and cephalosporin, a model of lysozyme–cephalosporin interaction, lg[(I0 – I)/I]=lgKD + nlg[D], was established. Using the proposed model, the interaction parameters and the binding ability of lysozyme with cephalosporin were successfully obtained, and the results agreed very well with the results obtained by fluorescence.

The expression level of surface marker Trop2 in gastric cancer stem-like cells

Blood and Genomics (2017)

Qi Tang Xingwang Kuai Zhao Wei Guipeng Ding Zhenning Qiu

This study aims to prepare gastric cancer stem-like cells(GCSCs) using a serum-free suspension culture, then identify it preliminarily, and observe the expression level of Trop2. Serum-free DMEM/F12 medium and low-adhesion dish were used for suspended culture of gastric cancer (GC) cell lines MGC803. The morphological characteristics of cell spheres were observed by optical microscope; the positive rates of the CD44, CD54, EpCAM and Trop2 in MGC803 and MGC803-spheres were detected by FACS; the changes of the cell cycle in the MGC803-spheres were explored by FACS and compared with that in MGC803; the mRNA level of cancer stem cells(CSCs) regulatory genes and Trop2 in MGC803-spheres and MGC803 were detected by qRT-PCR. MGC803-spheres formed after MGC803 was cultured in serum-free medium for about 14 days; the levels of CD44, CD54, EpCAM and Trop2 in MGC803-spheres group were higher than those in MGC803 group (P<0.05). The G1 phase of cell cycle in the MGC803-spheres group was obviously lower than that in MGC803 group, and the S phase of the cell cycle in MGC803-spheres group was obviously higher than that in the MGC803 group (P<0.05). The mRNA level in the CSCs regulatory genes (Oct4, Snail, Nanog) and Trop2 in MGC803-spheres group were much higher than those in MGC803 group (P<0.05). MGC803-spheres could form in serum-free and suspension culture condition. The type of cells has the characteristic of CSCs, which appears in a higher proliferation state and over expression CSCs regulating genes and Trop2.
