High-quality medical microscopic images used for diseases detection are expensive and difficult to ***,low-resolution images are favorable due to their low storage space and ease of sharing,where the images can be enlarged when needed using Super-Resolution(SR)***,it is important to maintain the shape and size of the medical images while enlarging *** of the problems facing SR is that the performance of medical image diagnosis is very poor due to the deterioration of the reconstructed image ***,this paper suggests a multi-SR and classification framework based on Generative Adversarial Network(GAN)to generate high-resolution images with higher quality and finer details to reduce *** proposed framework comprises five GAN models:Enhanced SR Generative Adversarial Networks(ESRGAN),Enhanced deep SR GAN(EDSRGAN),Sub-Pixel-GAN,SRGAN,and Efficient Wider Activation-B GAN(WDSR-b-GAN).To train the proposed models,we have employed images from the famous BreakHis dataset and enlarged them by 4×and 16×upscale factors with the ground truth of the size of 256×256×***,several evaluation metrics like Peak Signal-to-Noise Ratio(PSNR),Mean Squared Error(MSE),Structural Similarity Index(SSIM),Multiscale Structural Similarity Index(MS-SSIM),and histogram are applied to make comprehensive and objective comparisons to determine the best methods in terms of efficiency,training time,and storage *** obtained results reveal the superiority of the proposed models over traditional and benchmark models in terms of color and texture restoration and detection by achieving an accuracy of 99.7433%.

氮掺杂碳纳米管负载的Ru和Pd催化剂上异丙醇的转化(英文)

Ru and Pd (2 wt%) loaded on pure and on Ndoped carbon nanotubes (NCNTs) were prepared and tested using the isopropyl alcohol decomposition reaction as probe reaction. The presence of nitrogen functionalities (pyridinic, pyrrolic, and quaternary nitrogen) on the nitrogen doped support induced a higher metal dispersion: Pd/NCNT (1.8 nm) < Pd/CNT (4.9 nm), and Ru/NCNT (2.4 nm) < Ru/CNT (3.0 nm). The catalytic activity of the supports was determined first. Isopropyl alcohol conversion produces acetone on CNTs while on NCNTs it led to both dehydration and dehydrogenation products. At 210 °C and in the presence of air, the isopropyl alcohol conversion was higher on the NCNTs (25%) than on the CNTs (11%). The Pd loaded catalysts were more active and more selective than the Ru ones. At 115 °C, the Pd catalysts were 100% selective towards acetone for a conversion of 100%, whereas the Ru catalysts led to dehydration and dehydrogenation products. The nitrogen doping induced the appearance of redox properties when oxygen is present in the reaction mixture.

Water Shortage in MENA Region: An Interdisciplinary Overview and a Suite of Practical Solutions

引用

Journal of Water Resource and Protection 2013年第4期5卷 49-58页

作者： anas Zyadin University of Eastern Finland Joensuu Finland

The chronic water shortage in the Middle East North Africa (MENA) region is a perplexing issue, undoubtedly because various operational sectors, multi-institutions and stakeholders are inextricably interconnected. In the light of climate variability and the unprecedented population growth rate, the per capita water resources and biocapacity will continue plummeting, and the demand-gap will seriously expand. Existing water quantification agreements have been deemed inefficient to solve the problem of naturally diminishing water resources and thus require immediate re-assembling. Most scholarly endeavors, including key international organizations, NGOs, and “Think Tank” policy briefs have limitedly addressed water shortage in contexts of regional politics, mass media, and, importantly, from social psychology perspectives. Therefore, a thorough analysis and interdisciplinary approach is required to find a feasible and suitable framework of solutions and from a multi-perspective podium. A synthesis of cross-sectorial bottlenecks that are crucial to water management is presented, and a suite of practical recommendations are introduced to water authorities and governments. This study argues that in the shadow of the region’s political instability, the clash of ideologies and its repercussions, and issues of national security and sovereignty, regional cooperation on water issues remain prognostications. In this essence, governments of MENA countries are urged to develop measures to substantially increase the water supply through innovative approaches. Such measures include enhancing the capacities of water harvesting, maximizing the storage capacities of the built dams, and deploying groundwater recharge techniques. Furthermore, seawater and brackish water desalination through clean energy technologies is a contemporary solution with socio-economic and multiple benefits. Multi-billion water projects might not be suitable approach in the absence of external funding and the

Minimal access procedures show successes in various several medical fields. This issue brings a specific use of laparoscopy to the front to discuss in more detail which is the liver tumour resection. And, it’s the high time for laparoscopy to be highlighted regarding to hepatobilliary system. It is significantly important to gain most of the benefits of the laparoscopy technology. Its advantages are already achieved in other operation type inside the body cavity such as cholecystectomy.

The dependence of the magnetic properties on the particle size of recycled HDDR Nd-Fe-B powders was investigated,with the aim to assess the reprocessing potential of the end-of-life scrap magnets via spark plasma sintering(SPS).The as received recycled HDDR powder has coercivity(Hci)=830 kA/m and particles in the range from 30 to 700 μm(average 220 μm).After burr milling,the average particle size is reduced to 120 μm and subsequently the Hci of fine(milled) powder was 595 kA/*** plasma sintering was exploited to consolidate the nanograined HDDR powders and limit the abnormal grain *** optimal SPS-ing of coarse HDDR powder at 750℃for 1 min produces fully dense magnets with Hci=950±100 kA/m which further increases to 1200 kA/m via thermal treatment at 750℃for 15 *** burr milled fine HDDR powder under similar SPS conditions and after thermal treatment results in Hci=940 kA/*** fine powder is further sieved down from 630 to less than 50 μm mesh size,to evaluate the possible reduction in Hci in relation to the particle *** gain in oxygen content doubles for 200 μm).The XRD analysis for fractionated powder indicates an increase in Nd2O3 phase peaks in the finer(200 μm) to 460 kA/m in the fine sized particles(200 μm) is higher than 930 kA/m and it falls abruptly to just 70 kA/m for the fine sized particles(1000 kA/m only up to 100 μm sized fractions with>90% sintered *** full densification(>99%) is observed only in the coarse *** loss of coercivity and lack of sinterability in the fine sized particles(<100 μm) are attributed to a very high oxygen *** implies that durin
