Abstract

MeanShift algorithm has been widely used in tracking tasks because of its simplicity and efficiency. However, the traditional MeanShift algorithm needs to label the initial region of the target, which reduces the applicability of the algorithm. Furthermore, it is only applicable to the scene with a large overlap rate between the target area and the candidate area. Therefore, when the target speed is fast, the target scale change, shape deformation or the target occlusion occurs, the tracking performance will be deteriorated. In this paper, we address the challenges above-mentioned by developing a tracking method that combines the background models and the graded features of color-names under the MeanShift framework. This method significantly improve performance in the above scenarios. In addition, it facilitates the balance between detection accuracy and detection speed. Experimental results demonstrate the validation of the proposed method., Comment: 12 pages, 5 figures

Abstract

In this paper, we mainly study the theory of linear codes over the ring $R =\mathbb{Z}_4+u\mathbb{Z}_4+v\mathbb{Z}_4+uv\mathbb{Z}_4$. By the Chinese Remainder Theorem, we have $R$ is isomorphic to the direct sum of four rings $\mathbb{Z}_4$. We define a Gray map $\Phi$ from $R^{n}$ to $\mathbb{Z}_4^{4n}$, which is a distance preserving map. The Gray image of a cyclic code over $R^{n}$ is a linear code over $\mathbb{Z}_4$. Furthermore, we study the MacWilliams identities of linear codes over $R$ and give the the generator polynomials of cyclic codes over $R$. Finally, we discuss some properties of MDS codes over $R$.

Abstract

The thermal degradation of polylactide (PLA) during melt processing may lead to poor product properties. In this study, a unique Raman system was applied to explore the thermal degradation kinetics of molten PLA under five different temperatures and three atmospheres. It was found that the intensity of specific Raman bands correlated with the concentration of functional groups in the PLA during the degradation process. Kinetic models for thermal degradation were established based on the intensity of the characteristic band of C-COO. Kinetic parameters determined by kinetic models quantitatively revealed the effect of temperature and atmosphere on thermal degradation. Furthermore, time sweep rheological tests using the same degradation conditions were performed for verification, and the results corroborated the spectral analyses. This investigation demonstrates the feasibility of Raman spectroscopy for thermal degradation kinetic analysis.

Abstract

Photodynamic therapy (PDT) agents induce photodamage only where photosensitizers localize in tumor cells. Since apoptosis is a major pathway of PDT-mediated cell death in vivo, the therapeutic efficacy of PDT drugs against tumor cells may be improved by regulating intrinsic apoptosis. Mitochondria are the major intracellular organelles that regulate apoptosis, thus triphenylphosphonium, a well-known mitochondria-targeting molecule, was appended to a photoactive platinum diimine complex. The ability of the triphenylphosphonium-appended complex to generate singlet oxygen was assessed by fluorescence spectroscopy using 1,3-diphenylisobenzofuran as a probe. The photocytotoxicity towards HeLa cells (human cervical cancer cell line) or HL-7702 cells (human liver cell line) was assessed by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assays. The platinum complex has moderate capability to generate singlet oxygen and it has more potent photocytotoxicity than its analogue Pt-CA. Both platinum diimine complexes studied are largely nontoxic to human liver cells either in the dark or after irradiation. [ABSTRACT FROM AUTHOR]

Abstract

Behçet's disease (BD) is a rare condition that is seldom associated with hematological malignancies. In this case report, we present the unique case of a 7‐year‐old girl diagnosed with juvenile myelomonocytic leukemia (JMML) and intestinal BD. The patient received allogeneic hematopoietic stem cell transplantation (allo‐HSCT), which resulted in complete remission of both JMML and BD. Our findings suggest that allo‐HSCT may be a feasible treatment option for JMML patients with coexisting BD, and holds promise for achieving remission of both illnesses. However, further clinical investigations are needed to validate these findings. [ABSTRACT FROM AUTHOR]

43. Spatial–Temporal Multiscale Constrained Learning for mmWave-Based Human Pose Estimation

Author

Chen, Lin, Guo, Xuemei, Wang, Guoli, and Li, Hongyi

Abstract

It is a challenging task to reconstruct human pose from millimeter wave (mmWave) radar point clouds due to their sparsity and sensitivity to multipath noise. In order to enhance the inference ability of deep learning models in processing sparse radar point clouds, a learning paradigm with spatial and temporal multiscale constraints is proposed, utilizing prior relationships in skeletal structure and joint movements in both time and space to constrain the learning of pose sequences. Specifically, the proposed spatial multiscale constraint block learns the spatial constraint relationships of human joints using three different scales: adjacent joint constraint, part-level kinematic constraint, and global joint constraint, by which the spatial joint constraint features are aggregated by fusion gate mechanism. On the other hand, the temporal multiscale constraint block is devised to learn the temporal constraint relationships of the joint trajectories using the information of the joint itself and local context-information in time domain. Compared with the single-scale constrained learning paradigm, the potential advantage of the proposed method is that it can reduce the impact of random missing and noise in radar data. Finally, the effectiveness and superiority of the proposed method are fully demonstrated through the experimental results on two public datasets of human pose estimation based on mmWave radar.

44. MPTFormer: Toward Robust Arm Gesture Pose Tracking Using Dual-View Radar System

Author

Chen, Lin, Guo, Xuemei, and Wang, Guoli

Abstract

Locating human joints using low-cost commercial millimeter-wave (mmWave) radars is an emerging technology. Compared to single-view radar, dual-view radar fusion is more efficient for robust arm gesture pose tracking since it can capture a wider area of human reflection and radial velocity in both directions. One challenging task for dual-view radar fusion is to effectively utilize the reflection points’ spatial and velocity information and focus perceptual cues related to joint position and velocity for accurate joint tracking. In this article, we propose a millimeter-wave pose tracking transformer (MPTFormer), a method for arm gesture pose tracking using both front- and side-view mmWave radars. Specifically, MPTFormer consists of a multidomain fusion transformer (MFFormer) and a joint tracking transformer (JTFormer). In the MFFormer, joint position and velocity estimation tasks are set, and the range–azimuth map (RAM) and range–Doppler map (RDM) of the dual-view radar are set as token embeddings, which interacted with joint position and velocity tokens for learning perceptual cues related to joint position and velocity as well as joint constraint relationships. Meanwhile, the nonlocal dependencies between dual-view radar and its multidomain features are mined to obtain good global feature representation. In the JTFormer, a hybrid learning architecture of the temporal transformer and long short-term memory (LSTM) is designed, which tracks the joint position according to the global and local features of the joint in the temporal dimension. Finally, in the pose-tracking task containing 12 different arm gestures, the proposed method can achieve 25.2 mm mean per joint position error (MPJPE) and 19.1 mm Procrustes analysis-MPJPE (P-MPJPE).
