1Disruption of the Sugar Transporters AtSWEET11 and AtSWEET12 Affects Vascular Development and Freezing Tolerance in Arabidopsis显示文摘Dear Editor, In plants,the transport of sugars from the site of biosynthesis to the site of utilization or storage relies on sugar transporters located in different subcellular compartments and different vascular cell types.The SWEET sugar transporter family is one such class and is represented by 17 members in Arabidopsis.AtSWEET1 was the first plant SWEET transporter to be characterized;it acts as a glucose uniporter in multiple systems (Chen et al.,2010).Rozenn Le Hir Lara Spinner Patrick A.

2二硼化钛对Al2024−TiB_(2)非原位复合材料摩擦磨损性能的影响显示文摘用搅拌铸造法制备不同质量分数二硼化钛(TiB_(2))颗粒增强的铝基复合材料,并研究其摩擦磨损性能。采用销−盘式摩擦试验机对Al2024−TiB_(2)复合材料进行干滑动磨损试验。为了研究摩擦学参数对复合材料的影响,对载荷、滑动距离和滑动速度等参数进行调整。显微组织表征结果表明,TiB_(2)颗粒分散均匀并与基体有良好的结合。实验结果表明,与Al2024合金相比,复合材料的摩擦磨损率更低,而Al2024合金和复合材料的磨损率均随载荷、滑动速度和滑动距离的增加而增加。然而,Al2024合金和复合材料的摩擦因数均随载荷的增大而减小,而随滑动速度和滑动距离的增大而增大。对磨损表面和磨屑的扫描电镜研究表明,耐磨性的提高归因于细小磨屑的形成。Dipankar DEY Abhijit BHOWMIK Ajay BISWAS 2021Transactions of Nonferrous Metals Society of China2021,31,5:4
3苦苣苔科植物Lysionotus bijantiae的名实订正显示文摘通过查阅相关文献和标本,作者发现近期发表的苦苣苔科吊石苣苔属植物一新种——Lysionotus bijantiae D. Borah&A. Joe实为鉴定错误,应是汉克苣苔属的长圆叶汉克苣苔\[Henckelia oblongifolia (Roxb.)D. J. Middleton&Mich. M?ller\]\[原长圆叶唇柱苣苔Chirita oblongifolia (Roxb.) Sinclair\]。Lysionotus bijantiae的模式标本采集于中国西藏东南部地区的喜马拉雅南坡,该地区苦苣苔植物多样性较为丰富。作者因其花具2枚发育雄蕊而将其归于吊石苣苔属,花萼分裂不达基部而与吊石苣苔属其他相关种类比较,而忽略了其种子先端不具附属物的特征。通过电镜扫描观察到,该种在墨脱境内居群以及其模式产地居群的种子均无附属物,从而证实了该种不是吊石苣苔属的物种,而是属于汉克苣苔属。因此,作者将Lysionotus bijantiae处理为Henckelia oblongifolia的新异名,同时提供了长圆叶汉克苣苔的彩色图片(含种子扫描图)、选定模式标本,并给出了吊石苣苔属和汉克苣苔属的区分方法和主要识别特征,不仅为这两个属的物种鉴定提供了参考,而且避免更多的物种分类混淆问题出现。蔡磊 BORAH Dipankar 刀志灵 温放 2020广西植物2020,40,10:4
4Plasma Heating Induced by Tadpole-like Downflows in the Flaring Solar Corona显示文摘As one of the most spectacular energy release events in the solar system,solar flares are generally powered by magnetic reconnection in the solar corona.As a result of the re-arrangement of magnetic field topology after the reconnection process,a series of new looplike magnetic structures are often formed and are known as flare loops.A hot diffuse region,consisting of around 5–10 MK plasma,is also observed above the loops and is called a supra-arcade fan.Often,dark,tadpole-like structures are seen to descend through the bright supra-arcade fans.It remains unclear what role these so-called supra-arcade downflows(SADs)play in heating the flaring coronal plasma.Here we show a unique flare observation,where many SADs collide with the flare loops and strongly heat the loops to a temperature of 10–20 MK.Several of these interactions generate clear signatures of quasi-periodic enhancement in the full-Sun-integrated soft X-ray emission,providing an alternative interpretation for quasi-periodic pulsations that are commonly observed during solar and stellar flares.Tanmoy Samanta Hui Tian Bin Chen Katharine KReeves Mark C.M.Cheung Angelos Vourlidas Dipankar Banerjee 2021The Innovation2021,2,1:3
5New exact solutions for the time fractional coupled Boussinesq-Burger equation and approximate long water wave equation in shallow water显示文摘The aim of the article is to construct exact solutions for the time fractional coupled Boussinesq-Burger and approximate long water wave equations by using the generalized Kudryashov method.The fractional differential equation is converted into ordinary differential equations with the help of fractional complex transform and the modified Riemann-Liouville derivative sense.Applying the generalized Kudryashov method through with symbolic computer maple package,numerous new exact solutions are successfully obtained.All calculations in this study have been established and verified back with the aid of the Maple package program.The executed method is powerful,effective and straightforward for solving nonlinear partial differential equations to obtain more and new solutions with the integer and fractional order.Mostafa M.A.Khater Dipankar Kumar 2017Journal of Ocean Engineering and Science2017,2,3:3
6新型蛋白质中的氨基酸(综述)显示文摘氨基酸(Amino Acid,AA)是所有动物体内蛋白质的基本构架,在细胞中起着多重调节功能。对猪而言,AA分两大类:必需氨基酸(Essential Amino Acid,EAA)和非必需氨基酸(Non-Essential Amino Acid,NEAA)。EAA无法在动物的生理系统内自然合成,因此EAA必须通过日粮提供给动物;而NEAA则可在动物体内合成,因此无需在日粮中额外添加。在单胃动物所需的20种AA中(表1),猪的EAA仅为9种(蛋氨酸、组氨酸、苯丙氨酸、亮氨酸、异亮氨酸、苏氨酸、色氨酸、赖氨酸和缬氨酸)。这种不可缺少的AA因动物物种的不同也有所不同。韩浩月(译) 夏俊花(审) 罗静如(制图) Sanjib Borah Dipankar Paul 2018国外畜牧学(猪与禽)2018,38,1:3
7Thermal analysis of a constructal T-shaped porous fin with simultaneous heat and mass transfer显示文摘The present work establishes an analytical model for computing the temperature distribution, fin efficiency and optimum design parameters of a constructal T-shaped porous fin operating in fully wet condition. For more practical results, this study considers a cubic polynomial relationship between the humidity ratio of saturated air and the corresponding fin surface temperature. The temperature distribution has been determined by solving the highly non-linear governing equations using a semi-analytical transformation technique called Differential Transform Method. A comparison of the results with that of a numerical model shows that this transformation method is a very efficient and convenient tool for solution of non-linear problems. The effects of various geometric, thermo-physical and psychometric parameters on the temperature distribution, fin efficiency and optimum design condition have been investigated. Also, a comparison has been presented between solid and porous fins and the results point out that by selecting an appropriate value of porosity, the heat transfer rate can be increased than the corresponding solid fin.Saheera Azmi Hazarika Tuhin Deshamukhya Dipankar Bhanja Sujit Nath 2017Chinese Journal of Chemical Engineering2017,25,9:3

10A novel microscale selective laser sintering(μ-SLS)process for the fabrication of microelectronic parts显示文摘One of the biggest challenges in microscale additive manufacturing is the production of three-dimensional,microscale metal parts with a high enough throughput to be relevant for commercial applications.This paper presents a new microscale additive manufacturing process called microscale selective laser sintering(μ-SLS)that can produce true 3D metal parts with sub-5μm resolution and a throughput of greater than 60mm^(3)/hour.Inμ-SLS,a layer of metal nanoparticle ink is first coated onto a substrate using a slot die coating system.The ink is then dried to produce a uniform nanoparticle layer.Next,the substrate is precisely positioned under an optical subsystem using a set of coarse and fine nanopositioning stages.In the optical subsystem,laser light that has been patterned using a digital micromirror array is used to heat and sinter the nanoparticles into the desired patterns.This set of steps is then repeated to build up each layer of the 3D part in theμ-SLS system.Overall,this new technology offers the potential to overcome many of the current limitations in microscale additive manufacturing of metals and become an important process in microelectronics packaging applications.Nilabh K.Roy Dipankar Behera Obehi G.Dibua Chee S.Foong Michael A.Cullinan 2019Microsystems & Nanoengineering2019,5,1:2
11Emerging insights into HAUSP (USP7) in physiology, cancerand other diseases显示文摘Herpesvirus-associated ubiquitin-specific protease(HAUSP)is a USP family deubiquitinase.HAUSP is a protein of immense biological importance as it is involved in several cellular processes,including host-virus interactions,oncogenesis and tumor suppression,DNA damage and repair processes,DNA dynamics and epigenetic modulations,regulation of gene expression and protein function,spatio-temporal distribution,and immune functions.Since its discovery in the late 1990s as a protein interacting with a herpes virus regulatory protein,extensive studies have assessed its complex roles in p53-MDM2-related networks,identified numerous additional interacting partners,and elucidated the different roles of HAUSP in the context of cancer,development,and metabolic and neurological pathologies.Recent analyses have provided new insights into its biochemical and functional dynamics.In this review,we provide a comprehensive account of our current knowledge about emerging insights into HAUSP in physiology and diseases,which shed light on fundamental biological questions and promise to provide a potential target for therapeutic intervention.Seemana Bhattacharya Dipankar Chakraborty Malini Basu Mrinal K Ghosh 2018Signal Transduction and Targeted Therapy2018,3,1:2

15Assessment of surface and subsurface waterlogging, water level fluctuations, and lithological variations for evaluating groundwater resources in Ganga Plains显示文摘In the present study,the multi-temporal satellite images of IRS P6 LISS III were used to map waterlogging dynamics over different seasons.An area of 594.36 km2(6.75%)and 4.17 km^(2)(0.04%)was affected by surface waterlogging during pre and postmonsoon season,respectively.The average annual groundwater level fluctuations were calculated using 18 years(1990-2007)pre and postmonsoon groundwater level data to identify the areas which are under groundwater induced waterlogging conditions.The soil map clearly indicates that salinity and sodicity exhibit the highest severity and occur in areas with shallow groundwater levels.The hydrogeomorphical units mapped using IRS P6 LISS III satellite images are flood plain,alluvial plain,paleochannels,and oxbow lakes.The study revealed that 44.65%areas have very good to excellent groundwater resources.The litholog data clearly indicate an alternating sequence of clay and sand in which deep aquifers made up of coarse sand would be best suited for adequate water supply and good groundwater quality.The integrated study utilizing digital spatial data pertaining to waterlogging,soil salinity,water level fluctuation,and lithological variation proved that planning of any surface and subsurface water resources development activity should be taken up after assessments of said parameters.Arvind Chandra Pandey Suraj Kumar Singh M.S.Nathawat Dipankar Saha 2013International Journal of Digital Earth2013,6,3:1
