Automatic image classification is the first step toward semantic understanding of an object in the computer vision *** key challenge of problem for accurate object recognition is the ability to extract the robust features from various viewpoint images and rapidly calculate similarity between features in the image database or video *** order to solve these problems,an effective and rapid image classification method was presented for the object recognition based on the video learning *** optical-flow and RANSAC algorithm were used to acquire scene images from each video *** the selection of scene images,the local maximum points on corner of object around local area were found using the Harris corner detection algorithm and the several attributes from local block around each feature point were calculated by using scale invariant feature transform(SIFT)for extracting local ***,the extracted local descriptor was learned to the three-dimensional pyramid match *** results show that our method can extract features in various multi-viewpoint images from query video and calculate a similarity between a query image and images in the database.

Dear Editor,Vascular endothelial growth factor-A(VEGFA,also known as VEGF)is a critical angiogenic factor that regulates the physiological and pathological blood vessel growth.1 Increased abundance of VEGF in the eye underlies many forms of aberrant ocular angiogenesis and resultant vision loss,including in neovascular age-related macular degeneration(nvAMD),proliferative diabetic retinopathy(PDR).

Prussian blue and its analogues as advanced supercapacitor electrodes

Journal of Energy Chemistry 2020年第11期29卷 206-229页

作者： Emad S.Goda Seungho Lee Muhammad Sohail Kuk ro Yoon Organic Nanomarerials Lab Department of ChemistryHannam UniversityDaejeon 34054Republic of Korea Department of Chemistry Hannam UniversityDaejeon 34054Republic of Korea Fire Protection Laboratory National Institute of Standards136.Giza 12211Egypt Advanced Energy and System Engineering University of Science and TechnologyDaejeon 34113Republic of Korea

Remarkable attention has been directed to Prussian blue(PB) and its analogues(PBA) as one of the most widely used metal-organic frameworks(MOFs) especially in the field of energy storage devices due to their fabulous features such as 3D open framework, high surface area, controllable distribution of pores and the low cost. Nevertheless, their depressed conductivity causes some insulation when being used as an electrode for supercapacitors leading to be restricted in further applications particularly the electronics. To the best of our knowledge, our review aimed primarily to give a total picture of the research that was done on utilizing PB and PBA for fabricating the electrodes of supercapacitor, studying their synthesis approaches in addition to the hybridization with other materials such as graphene, CNTs and conducting polymer. It also addresses the transformation of PB or PBA into other interesting nanostructures such as oxides, sulfides, and bicomponent of graphitic carbon nitride/metal oxides, as well. Furthermore,It exhibits various avenues for overcoming their disadvantages of bad cycle life, retention rate and not achieving the desired values of energy/power densities opening the door for enlarging the number of researches on their application as supercapacitors.

Breast cancer metastasizing to the stomach mimicking primary gastric cancer: A case report

Breast cancer with stomach metastasis rare with an incidence of 1% or less among metastatic breast cancer patients. We experienced a case of breast cancer metastasizing to the stomach in 65-year-old female patient. She experienced dyspepsia and poor oral intake before visiting the clinic. Diffuse infiltration with nodular mucosal thickening of the stomach wall was observed, suggesting advanced gastric cancer based on gross endoscopic finding. Spread of poorly cohesive tumor cells in the gastric mucosa observed upon hematoxylin and eosin stain resembled signet ring cell carcinoma, but diffuse positive staining for GATA3 in immunohistochemical stain allowed for a conclusive diagnosis of breast cancer metastasizing to the stomach. Based on the final diagnosis, systemic chemotherapy was administered instead of primary surgical resection. After 2 cycles of docetaxel administration, she showed a partial response based on abdominal computed tomography scan. This case is an unusual presentation of breast cancer metastasizing to the gastrointestinal tract.

Making cancer fat:reprogramming of lipid metabolism by CD147 in hepatocellular carcinoma

引用

Chinese Journal of Cancer Research 2016年第3期28卷 380-382页

作者： Hye-Lim Ju Simon Weonsang ro Institute of Gastroenterology Yonsei University College of Medicine

Over the past few years, de novo lipogenesis has taken central stage in the field of cancer metabolism （1）. Large amount of lipids is needed for synthesis of membranes, signaling molecules, lipoproteins, etc. to support rapidly growing tumor cells （2-4）. Reports have shown that neoplastic tissues show aberrant activation of de novo lipogenesis and that inhibition of different enzymes within the fatty acid biosynthesis pathway can block cancer cell growth （2,5-9）. Meanwhile, the importance of fatty acid oxidation （FAO） in cancer metabolism is being increasingly recognized. FAO is the catabolic process by which lipids are utilized to produce energy. Recent studies implicated that the key regulatory enzymes in FAO such as carnitine palmitoyltransferase 1 （CPT1） and peroxisomal acyl-coenzyme A oxidase 1 （ACOX1） regulate cancer development （10,11）.

Mechanically induced phase transformation of zinc sulfide

引用

Particuology 2015年第1期13卷 1-10页

作者： Cornelia Damm Patrick Armstrong Christian roβkopf Stefan romeis Wolfgang Peukert University Erlangen-Nuremberg Institute of Particle Technology

Molecular dynamics （MD） simulations of the consecutive compression-decompression cycles ot hexagonal zinc sulfide （wurtzite） nanoparticles predict an irreversible phase transformation to the cubic *** phase transformation commences at the contact area between the particle and the inden- ter and proceeds with the number of compression cycles. Dislocations are visible for a particle size above 5nm. Results from wet grinding and dry powder compression experiments on a commercial wurtzite pigment agree qualitatively with MD simulation predictions. X-ray diffraction patterns reveal that the amount of cubic polymorph in the compressed samples increases with pressure applied to the powder. In comparison with powder compression, wet milling leads to a more pronounced phase transformation. This occurs because the particles are exposed to a large number of stress events by collision with the grinding media, which leads to the formation of defects and new surface crystallites by particle fracture. According to the MD simulations, phase transformation is expected to occur preferentially in surface crystallites because they experience the highest mechanical load. Because of the phase transformation, the wet ground and compressed samples exhibit a lower photo- luminescence intensity than the feed material. In comparison with powder compression, milling reduces the photoluminescence intensity more substantially. This occurs because a higher defect concentration is formed. The defects contribute to the phase transformation and photoluminescence quenching.

The silent spermatozoon： are man-made endocrine disruptors killing male fertility？

Asian Journal of Andrology 2013年第2期15卷 165-168,I0004页

作者： bradley D Anawalt Department of Medicine University of Washington Seattle WA 98195 USA

In 1992, a Danish group led by Skakkebaek , reported in a meta-analysis that global mean sperm counts were fallingandthat testicular cancer, hypospadias and cryptorchidism were increasing. They hypothesized that environmental factors were the cause. Their rectaanalysis was criticized subsequently for many methodological flaws. However, their controversial metamlysls and hypothesis spurred pubfic and scientific interest in the study of male reproductive function and stimulated more rigorous scientific work in the area. Subsequent research has not convincingly supported their hypothesis, However, it is caudal to continue high quality studies of the effects of drugs and manmade pollutants on male eeproductlve function.
