This paper develops an integrated fuzzy two-layer supply chain for manufacturersand retailers with defective and non-defective types of products. The manufacturerproduces up to a specific time, including both faulty and non-defective items, andpost-screening only the non-defective item sends to the retailer. The strategy of theretailer is to do the screening of items received from the ***, the perfect quality items use to fulfill the demand of thecustomer, and the defective items are reworked. The retailer considers thatcustomer demand is time and reliability dependent. The proposed supply chainconsiders probabilistic deterioration for the manufacturer and retailers. Theoptimum solution of the given model is evaluated for both the cases of crispand fuzzy environments on the strategies such as production rate, unitproduction cost, idle time, screening, rework, etc. Managerial insights and theeffect of parameters on the optimal inventory under fuzziness are presented.

The streak-breasted scimitar Babblers of the Pomatorhinus ruficollis species complex are found in most of the forested habitats across southern and eastern Asia. The diversification history of this group is obscured by high plumage variation across populations and conflicting genetic signal across loci. We combined genetic and geographic data from several recent studies to investigate how these species diversified across China using both phylogenetic and ecological niche modeling analyses. These two lines of evidence are consistent in showing that two well-sampled species, P. reconditus and P. nigrostellatus, in central and southern China respectively, likely experienced a history of isolation and expansion as suitable habitat contracted during the last interglacial and expanded in patchy extent during the glacial maximum. The genetic analysis showed that populations of P. nigrostellatus on Hainan Island are very similar to the ones in nearby mainland southern China. We recovered two well-supported clades within P. reconditus that were not geographically structured with both containing individuals from the same localities across central China. This phylogenetic result corresponded to the ecological niche models that showed expansion from refugia since the last interglacial. This study illustrates the value of using an integrative approach and detailed geographic sampling to help understand the recent diversification of birds in China [Current Zoology 61 （5）： 910-921, 2015].

波士顿大都市区城市长期生态研究区(BMA-ULTRA-EX)项目是一个跨学科的项目,正在研究对城市生态系统有影响的社会经济和生物物理领域。波士顿地区正在经历着的城乡结合部的低密度城市扩张(郊区化)对自然资源和环境产生了一定的影响。与此同时,像波士顿这样的中心城市,伴随着商业中心和交通枢纽附近的有限的加密开发(致密),一些低收入社区正在面临着经济的衰落。这些社会经济力量竞争过程中的郊区化、致密化和撤资也对城市生态环境系统产生影响。通过景观规划措施来解决这些问题,需要一个积极主动的做法,将目前建成的土地集中发展,而在边缘郊区保护自然资源,同时在当前高密度的城市核心区增加绿化并提高生态系统服务功能。通过这种景观规划方法,研究小组利用一个利益相关者驱动的过程,制定出一套4个情景规划方案来探索区域的未来。描述了这个利益相关者参与的规划过程,并进行初步分析,最后,为其他从事情景规划的景观规划师们总结了项目的经验。

The present study highlights the potential application of zinc peroxide （ZnO2） nanomaterial as an efficient material for the decontamination of cyanide from contaminated water. A process patent for ZnO2 synthesis has been granted in United states of America （us Patent number 8,715,612; May 2014）, south Africa, Bangladesh, and India. The ZnO2 nanomaterial was capped with polyvinylpyrrolidone （PVP） to control the particle size. The PVP capped ZnO2 nanomaterial （PVP-ZnO2） before and after adsorption of cyanide was characterized by scanning electron microscope, transmission electron microscope, X-ray diffractorneter, Fourier transform infrared spectroscopy and time of flight-secondary ion mass spectrom- etry. The remaining concentration of cyanide after adsorption by PVP-ZnO2 was determined using ion chromatograph. The adsorption of cyanide over PVP-ZnO2 was also studied as a function of pH, adsorbent dose, time and concentration of cyanide. The maximum removal of cyanide was observed in pH range 5.8-7.8 within 15 rain. The adsorption data was fitted to Langmuir and Fruendlich isotherm and it has been observed that data follows both the isotherms and also follows second order kinetics.

Prostate cancer is the second most common cancer in men, with 1.1 million new cases worldwide reported by the World Health Organization in one recent year. Transrectal ultrasound （TRus）-guided biopsy has been used for the diagnosis of prostate cancer for over 2 decades, but the technique is usually blind to cancer location. Moreover, the false negative rate of TRus biopsy has been reported to be as high as 47%. Multiparametric magnetic resonance imaging （mp-MRI） includes T1- and T2-weighted imaging as well as dynamic contrast-enhanced （DCE） and diffusion-weighted imaging （DWI）. mp-MRI is a major advance in the imaging of prostate cancer, enabling targeted biopsy of suspicious lesions. Evolving targeted biopsy techniquesmincluding direct in-bore biopsy, cognitive fusion and software-based MRI-ultrasound （MRI-us） fusion--have led to a several-fold improvement in cancer detection compared to the earlier method. Importantly, the detection of clinically significant cancers has been greatly facilitated by targeting, compared to systematic biopsy alone. Targeted biopsy via MRI-us fusion may dramatically alter the way prostate cancer is diagnosed and managed.

The computational cost of numerical methods in microscopic-scales such as molecular dynamics(MD) is a deterrent factor that limits simulations with a large number of particles. Hence, it is desirable to decrease the computational cost and run time of simulations, especially for problems with a symmetrical domain. However, in microscopic-scales, implementation of symmetric boundary conditions is not straightforward. Previously, the present authors have successfully used a symmetry boundary condition to solve molecular flows in constant-area channels. The results obtained with this approach agree well with the benchmark cases. Therefore, it has provided us with a sound ground to further explore feasibility of applying symmetric solutions of micro-fluid flows in other geometries such as variable-area ducts. Molecular flows are solved for the whole domain with and without the symmetric boundary condition. Good agreement has been reached between the results of the symmetric solution and the whole domain solution. To investigate robustness of the proposed method, simulations are conducted for different values of affecting parameters including an external force, a flow density, and a domain length. The results indicate that the symmetric solution is also applicable to variable-area ducts such as micro-nozzles.
