Video shot segmentation using graph-based dominant-set clustering
No full textVideo shot segmentation is a solid foundation for automatic video content analysis, for most content based video retrieval tasks require accurate segmentation of video boundaries. In recent years, using the tools of data mining and machine learning to detect shot boundaries has become more and more popular. In this paper, we propose an effective video segmentation approach based on a dominant-set clustering algorithm. The algorithm can not only automatically determine the number of video shots, but also obtain accurate shot boundaries with low computation complexity. Experimental results have demonstrated the effectiveness of the proposed shot segmentation approach.Li Li, Xianglin Zeng, Xi Li, Weiming Hu, Pengfei Zh

China's Wind-Power Generation Policy and Market Development
No full textThe Chinese government set its wind power generation capacity target at 5 million kW for 2010 and 30 million kW for 2020 in its Medium to Long-term Renewable Energy Development Plan released in September 2007. The 11th Five-Year Renewable Energy Development Plan, announced in March 2008, doubled the 2010 target to 10 million kW, attracting much attention from relevant parties. This report considers the challenges and future course of the Chinese wind power development policies and other background factoes behind the government's upward revision to the wind power genration capacity in the 11th Five-Year Renewable Energy Development Plan.China, wind-power, Energy, market developments

Machine learning based prediction of piezoelectric energy harvesting from wake galloping
No full textWake galloping is a phenomenon of aerodynamic instability and has vast potential inenergy harvesting. This paper investigates the vibration response of wake galloping piezo-electric energy harvesters (WGPEHs) in different configurations. In the proposed system, astationary obstacle is placed upstream, and a cuboid bluff body mounted on a cantileverbeam with piezoelectric sheets attached to it, is placed downstream. Three different typesof WGPEHs were tested with different cross-section S of the upstream obstacles, namelysquare, triangular, and circular. At the same time, the tests were conducted by changing theequivalent diameter ratio g ¼ 1 2:5 of the upstream and downstream objects, the dimen-sionless distance between two objects’ centers L ¼ L=D ¼ 2 8, and the velocity spanU ¼ 2:93 14:54. The results reveal that S , g, L and U have significant effect on thevibration response of WGPEHs. Then, considering these four parameters as input features,this study has trained machine learning (ML) models to predict the root mean square val-ues of the voltage (V rms ) and the maximum displacement (ymax), respectively. The perfor-mance of three different ML algorithms including decision tree regressor (DTR), randomforest (RF), and gradient boosting regression trees (GBRT) on predicting V rms and ymax werecompared. Among them, the GBRT model performed optimally in predicting the V rms andymax . The GBRT model provides accurate predictions to V rms and ymax within the test range of S , g, L and U.<br/
Abstract 5357: OncoGxSelectTM - a beneficial supplement to comprehensive cancer genetic test
No full textAbstract
Genetic profiling of tumor has been widely accepted both in oncology research and clinical field. However, clinical doctors are sometimes overwhelmed by tremendous and complicated information provided by comprehensive genetic tests, although they are welcomed by research-oriented oncologists. In order to provide accurate key findings to aid diagnosis and treatment in clinical practice, a careful tailored NGS based test - OncoGxSelectTM was developed and validated. Targeting 7 popular cancer types (NSCLC, Colorectal cancer, Breast cancer, Melanoma, Thyroid cancer, Esophageal and GIST cancer), OncoGxSelectTM detects all 4 types of genomic alterations including single nucleotide mutation, insertion/deletion, copy number variation and gene rearrangement in tumor tissue for 12 well-characterized clinical actionable genes strictly following NCCN (National Comprehensive Cancer Network) guidelines. OncoGxSelectTM offers high sensitivity and specificity greater than 99%, low cost and fast turnaround time using both DNA and RNA as starting material from FFPE samples with as low as 10% tumor cell content. This CLIA certified and CAP accredited genetic test panel is a valuable supplement to clinical oncologists to further facilitate diagnosis and treatment choosing.

No full textAmorphization-induced electronic modulation of Gd(OH)<sub>3</sub> nanocages with enhanced enzymatic activities for antitumor therapy
No full textIn nanotechnology-based cancer therapy, modulating electronic states of nanomaterials is crucial for influencing spatiotemporal dynamic behaviors of intracellular reduction-oxidation and redox homeostasis. Although rare-earth transition metals with 4f electrons present electronic energy levels suitable for electronic modulation, its practical realization is challenging due to strong 4f electron localization. Theoretical studies indicate that amorphization can significantly alter the electronic states of the 4f-dominated nanomaterials. However, the isotropic nature of disordered structures poses challenges for morphology and dimensional regulation of amorphous nanomaterials, which is important in tumor therapy. In this study, we designed and synthesized amorphous Gd(OH)3 nanocages with regulated electronic states for antitumor therapy. The reduction of the Gd-O coordination number in the amorphous structure significantly diversifies the spatial occupancy, alters the electronic states, and enhances hole delocalization, thereby boosting the redox capability of the originally inert Gd3+ compound (half-filled 4f7 orbit). This results in unexpected peroxidase (POD)-like catalytic activity, with a Kcat of 3.49 × 104 s-1, which is an order of magnitude higher than that of the natural HRP enzyme. The amorphous Gd(OH)3 nanocages also show impressive antitumor effects both in vitro and in vivo, demonstrating that amorphization is an effective strategy for modulating the electronic states of rare earth elements and unlocking new catalytic and biomedical potential for advanced synthetic nanozymes.</p
