电气工程:1Electrical Engineering My decision to pursue graduate study in the United States is underscored by my desire to be a part of the graduate program at your institution. Purdue University offers the flexibility needed for such a vast and rapidly changing field. The research facilities and the faculty at the university are par excellent. Communications is an industry that has changed our lives. In a very short period it has changed the way we have looked at things since centuries. It is one industry that is going to shape our future for centuries to come. Hence my desire to do masters in electrical engineering with communications as my major. My interest in electronics blossomed during my high school years. It was the time when technology had begun to make an impact on the lives of people in India. Hence engineering with electronics as my major was the first choice for my undergraduate studies. Right since the beginning of my undergraduate study electronics is a subject that has fascinated me with its power of applications. The subjects that I have studied include Linear Electronics, Digital Electronics. These laid the foundation for my courses in Electronic Communication & Communication Systems at a later stage. My undergraduate studies already focus on the communications aspect of electronics. A masters degree in electrical engineering with communications as major field is the next logical step. For the past four months I have been working as a project trainee at the Indian Institute for Advanced Electronics. I am working on the design and development of a "PC Controlled Digital Serial Data Generator". This short stint has given me invaluable practical experience. It has given me the confidence to pursue a masters degree and also kindled a desire to do research. During the course of my work at IIAE, I have come across several scientists. Most of them work in different areas of communications. Interactions with them have made me realize the vastness and the scope of communications. My discussions with them convinced me that specializing in communications will suit me very well. The subject of research which interests me very much is spread spectrum communication systems. Coding theory and combinations is another research subject which arouses my curiosity. The subject Communication Theory which I am studying at present introduces these topics in theory. I am eager to find out more about the applications of coding theory to spread spectrum communication systems. In addition I have been a student member of the IEEE (Institute of Electrical and Electronics Engineers, Inc.) for the past three years. Through its workshops/seminars and publications like the 'The Spectrum' it has exposed me to a lot of emerging technologies in the field of communications. It is a strong belief in my family that the American education system has the best to offer in the whole world. This belief arises out of the experience that my parents had when they did their Masters of Science in the University of Pennsylvania during the years 1967-69. If I can get an opportunity to be a part of that intellectually stimulating environment, I am sure my talents will be put to optimal use. India is a developing country with an enormous potential in the information technology business. To serve the needs of this developing industry and more important its vast population, communications is going to become of utmost importance. Thus conditions here are very conducive to supplement my aspirations when I return after completing my graduate studies. 2Electrical Engineering As a graduate student, I will undertake research and coursework in Electrical Engineering to enhance my competencies in this field. I intend to complete my master's degree in order to pursue my doctorate. The research that I am most interested in pursuing at Northeastern University surrounds the optical properties of MEMS devices, and the development of substrate-based fast electro-optical interfaces. My interest in this area stems from my undergraduate study in MEMs development for tri-axial accelerometers. Engineering has been a key interest of mine since childhood. While still in grade school I enjoyed listening to my father, an electrical engineer, teach me about advances in technology, and was always eager to hear more. I was introduced to my first computer at the age of five, and have loved interacting with them ever since. My decision to study engineering as a career was no surprise to those who knew me. In college I found that I was always studying something I enjoyed. I believe it is because I enjoy my life and my work that I have been successful. Spending hours in the laboratory is not something that I dread, but instead I take pride in my work and its successful completion. One example of this that is still fresh in my mind is the successful design of a fully functional microprocessor in the Xilinx environment. All told, the project took over 150 hours of each design-team member's time. However, I did not look on it as a drain, but an experience for learning and a focus for my professional and technical development. When we finished the project we felt the sense of worth and pride in completion of a task that was once above our level of knowledge. Pursuing a graduate degree in the research field I have chosen also feels like a challenge, and I know that study will frustrate me at times. However, I feel that my commitment to learning will not be swayed. I feel confident in my ability to be creative in my perspective, and to persevere. My ultimate goal is to be an innovator in the field I have chosen to study. Professionalism and creativity are my most valued strengths. At the heart of my interest is the advancement of man in concert with his environment. My personal philosophy of life will matter greatly during my study and after its completion. That is why I devote time to reflection on my goals and their implications. Money has never been a motivator for my work, nor do I think it will be in the future. However, as a professional and a graduate, I realize that my earning potential will be significant. That is why I also commit myself to charity and fairness. In the past I have been a member of the Boy Scouts of America, and have achieved the rank of Eagle Scout. In the course of my experience in that organization, I learned respect and moral value. Now, as a member of the IEEE, I value my professional standing and its commensurate moral implications. Ethics in engineering is as important as technical skill, and as such I intend to uphold my own ethical obligations to the best of my ability. As a Northeastern University student, I would commit all that I have to offer to my study. I intend to pursue research in MEMS technology. At Rowan University as an undergraduate student I have already conducted some research and development of MEMS sensors for military applications, resulting in publication. An article, written by myself and my project member David Bowen and edited by our advisor Dr. Robert Krchnavek, was published in the NAVSEA Intelligent Ships Symposium Proceedings of 2001. The paper was titled "Designing a 3-Axis, Monolithic, MEMS-Based Accelerometer" and was under review for endorsement by the US Navy's NAVSEA facility in Philadelphia during that year. Building on my past success in MEMs design, I hope to advance my understanding. Through research at the graduate level, it is my hope to become familiar with, and innovate the design of MEMs Optics in hopes of creating a reliable and practical MEMs Electro-Optical Interface for use in consumer electronics. It is my hope, that through my research, optical waveguides for intradevice communication might be realized. Finally, my intent to pursue graduate study is laid plain. Study of MEMs optics is my intended focus, and I am committed to my goal. In pursuing a doctoral degree, I have closely analyzed myself to determine the reasons for my previous successes and my goals for the future. I have found that I do and have always enjoyed engineering, and that I have a strong desire to pursue my study further. I am prepared to commit myself to that study, and achieve what I have set out to do. 3I Wish to Pursue an MS Degree in Electrical Engineering During my senior year at Purdue University, I made a decision that has impacted the entire course of my education. While my classmates were making definite decisions about their career paths, I chose to implement a five-year plan of development and growth for myself. I designed this plan in order to examine various careers that I thought might interest me, as well as to expand upon my abilities at the time. As I was attaining a BS degree in Electrical Engineering, I decided to focus primarily on fields related to the VLSI (Very Large-Scale Integrated) circuits area. My main goals were either to gain work experience or to further my education by pursuing an MS degree in Electrical Engineering (MSEE). I saw an opportunity to both work and learn through employment at Xilinx Inc. Operating as a product engineer at a successful, high-tech semiconductor company has enabled me to utilize my technical and interpersonal skills in new and challenging ways. The position has also allowed me to interact with a multitude of departments including marketing, integrated circuit (IC) design, software/CAD development, manufacturing, reliability, accounting, and sales. I thus have gained an array of experience that extended beyond the parameters of my own responsibilities. In the workplace, I rely heavily upon the interpersonal techniques I developed as a counselor in a Purdue residence hall, as well as the organizational skills I had acquired through holding various leadership positions in cultural and engineering societies. I have also cultivated an interest in high-technology marketing that has continued to grow throughout my career. My experiences with Xilinx have heightened my hunger for knowledge in the VLSI field. Two months after joining the corporation, I applied to several part-time programs in the vicinity that would allow me to acquire an MSEE degree within two to three years. San Jose State seemed an ideal choice, for its evening MSEE courses would allow me to pursue two independent, full-time positions concurrently. The San Jose program has complimented my Xilinx duties well; both demand large levels of energy and enthusiasm while guiding me to my ultimate goal a high degree of education in VLSI sciences. The resources that I poured into both endeavors have reaped many gains. I have been promoted to a Product-Yield Engineering position within Xilinx's Coarse Grain Static Memory (CGSM) Product Engineering division. My extensive coursework plays a key role in my continued success at Xilinx. Relevant classes in advanced digital and analog VLSI design, as well as sub-micron ULSI technology, have allowed me to understand more completely the workings of Xilinx, a fab-less semiconductor company that also functions as a software and hardware design, testing, and marketing center. The gains in knowledge I have made through the combination of work experience and education have indeed been exponential. The academic records of my senior year at Purdue, coupled with my MSEE coursework, are ample proof of my dedication to learning. I feel I have overcome through hard work and dedication the brief "dry phase" I underwent at Purdue during the close of my sophomore and the first semester of my junior years. My performance at that time is in no way indicative of my usual achievements; they are instead the result of urgent family difficulties that required much foreign travel and serious attention to resolve. In May, I shall graduate with an MSEE degree from San Jose well ahead of my original estimates. This early graduation with Dean's Honors is the result of my firm belief in the value of diligence, as well as my renewed determination to strive for perfection in both work and school. I am now embarking on another five-year plan, during which I hope to fulfill several specific career goals. For instance, being part of a very dynamic and results-oriented Yield team at Xilinx calls for continuous development of computational and statistical techniques. The Yield team is divided to focus on specific process/fabrication issues and process (manufacturing) optimization. My own position is an integral part of the optimization group. Speed and cost issues continue to press high technology atmospheres towards optimization, probability and stochastic processes and systems, and rigorous simulations of mathematical models. The MS in EES&OR offered at your university will grant me the statistical knowledge that is crucial for process and production optimization in a fab-less environment. In addition, product engineering requires fundamental research on mathematical models for linear and non-linear programming, as well as the utilization of efficient computer software. I continuously employ the knowledge I gained at Purdue in Operations Research and advanced mathematics courses. Yet despite the value of these classes and my high performance in them, I now require further education to best fulfill my duties. An MS in the EES&OR field, will give me knowledge that is invaluable to a career in product development, project management and strategic planning. The program will allow me to improve decision-making skills in operations, strategy, and policy issues. I will strengthen my theory and application in countless areas:continuous, discrete, numerical optimization; probabilistic and stochastic processes; dynamic systems and simulation; economics, finance, and investment; decision analysis; dynamic programming and planning under uncertainty; operations and service; corporate and individual strategy; and private and public policy , the EES&OR program will not only help me to excel at Xilinx but will also further any future career. My commitment to work and education over the last three years proves that I will pursue this MS with enthusiasm and technical edge that the MS would provide is I will be working while attending Stanford, I shall mingle education with practical application, and bring to the table interesting problems from my experience and past education. Technical challenges encountered through projects in the EES&OR program will provide motivation and opportunity for methodological data collection, processing and presentation issues presented are integral to my future goals, and the management challenges raised will provide invaluable experience for professional practice. This will in turn build a solid foundation for a life-long career that can overcome any problem in decision-making. In addition, taking courses in economics, finance, and investment analysis will allow much growth of knowledge in investment issues in different industries. The EES&OR program thus appeals not only to my engineering, economics, science and mathematical background, but will compliment my technical abilities with the conceptual frameworks needed to analyze problems in operations, production, strategic planning, and marketing in the realm of emiconductor/IC/engineering systems. I feel that I am prepared to meet the challenges of the curriculum. My coursework in intermediate microeconomics and macroeconomics, international trade, operations research, linear algebra, and probabilistic methods, along with my extensive calculus background, will allow me to function well within the program. My long-term career goals include a move into marketing and product management. I believe that attaining this MS degree is the cornerstone to achieving my goals. It will give me the academic background necessary to succeed in product development, project management, and strategic planning. It will improve decision-making skills necessary for optimizing performance. The integration of two excellent programs in Economics Systems and Operations Research thus suits my current position and ties in with future goals perfectly by improving decision making in operations, strategy and policy. At present I desire to continue at Xilinx; attending a program that provides the flexibility and convenience of the SITN, is therefore imperative. Hence, being at Stanford as an HCP student alsoattracts me. I believe that Stanford is the best environment for me to achieve my goals while gaining exposure to and experience with a diverse student body and faculty. It is my belief that one continues to learn throughout one's life, and the most effective method of learning is through interaction with 's diversity offers an environment for learning, both inside and outside the classroom. I hope to share my varied knowledge with my classmates and to take from them a new understanding of topics that are foreign to me. I believe that no other school provides students with the combination of education and environment offered by Stanford. Its outstanding academic reputation, mingled with its diverse environment and thriving Bay Area location, creates an opportunity for growth that is second to none. I have many ambitions for myself as I embark on this stage of my life. I believe that an education from Stanford will provide invaluable experiences and skills that will allow me to become a successful and innovative business leader in the new millennium. 4Research Department of Biomedical Engineering is designed to research on and solve the bio-electrical and biomagnetic engineering problems in the field of biology and medicine with the aid of engineering principles and methods.

细胞期刊最新期

自然杂志近年来发展的很快,出版集团还出版了其它专业杂志如《自然医学》,《自然免疫学》,《自然遗传学》,《自然细胞生物学》,《自然神经科学》、《自然生物学技术》、《自然方法学》、《自然临床实践》、《自然结构和分子生物学》、《自然评论》,《自然化学》,《自然物理学》,《自然纳米技术》,《自然材料学》和《自然综述系列》,总共37个子系列杂志,另外还有其他语言版的《自然中国》,,《自然印度》等系列。应该说自然是乞今为止世界上最权威,最有影响力,学科最齐全,相对来说最为公正的科学杂志!其中的《自然医学》, 《自然免疫学》,《自然遗传学》三份的影响因子已和《自然》《科学》一样高,在专业领域里威望很高。《自然》杂志不光关注生命科学,还积极跟踪新兴科学像纳米技术和材料科学。个人的感觉是自然杂志以其亲民扑实的作风,敏锐的目光和分析和最其全的学科复盖面,大有一统科学文献江山的气概和实力。

《科学》(Science) 是美国科学促进会(AAAS)出版的一份学术杂志 。1880年,纽约新闻记者约翰·麦克尔创立了《科学》杂志,这份杂志先后得到了托马斯·爱迪生以及亚历山大·格拉汉姆·贝尔的资助。此后,由于财政困难《科学》于1882年3月停刊。一年后,昆虫学家Samuel H. Scudder使其复活并取得了一定的成功。然而到了1894年,《科学》重新陷入财政危机,随后被以500美元的价格转让给心理学家James McKeen Cattell。1900年,Cattell与美国科学促进会秘书Leland O. Howard达成协议,《科学》成为美国科学促进会的期刊。1944年Cattell去世后,AAAS成为《科学》新主人。这本杂志主要刊登最新的科学研究成果。同时,《科学》也刊登关于科学的新闻、关于科技政策、科学家感兴趣的事务的观点。《科学》刊登各个学科的原创论文。目前,《科学》是全世界最权威的学术杂志之一,它的主要竞争对手是英国出版的《自然》杂志。像自然一样,《科学》杂志也是周刊,稿件学术水准和质量和自然比肩的,所不同的是科学没有子刊系列,也没有像《自然》那样的定期发表综述的刊物。因为这一点,《科学》杂志的影响力是不及《自然》的。

在生命科学领域,《细胞》(Cell)杂志为另一份同行评审科学期刊,主要发表实验生物学领域中的最新研究发现。《细胞》是一分深受关注并具有较高学术声誉的期刊,刊登过许多重大的生命科学研究进展。与《自然》和《科学》一样,是全世界最权威的学术杂志之一。单从其影响因子来看,它一直高于《自然》和《科学》两杂志,表明它所刊登的文章广受引用。

《细胞》是由爱尔塞维亚(Elsevier)出版公司旗下的细胞出版社(Cell Press)发行。《细胞》杂志主要以美东学术重镇波士顿为基地,以哈佛大学,麻省理工学院的生命科学家为后盾。《细胞》杂志前主编Benjamin Lewin不光主导这份生物学中最有份量的杂志,而且亲自主编教课书《Gene》,该书出版后广受好评,被殴美大学列为生物遗传学的第一首选教课书。 Lewin先生的知识也更新的很快,该书差不多每两年再版一次,现在已出版到第8版了。DNA双螺旋的发现者沃森教授也写了一本《Molecular Biology of Gene》不过,没有Lewin先生的书流行。《细胞》杂志也有许多子刊系列像《Cancer Cell》,《Stem Cell》,《Immunity》,《Neuron》和《Molecular Cell》等都是生命科学中的重量级刊物。再加上爱尔塞维亚(Elsevier)出版公司拥有的大量其他刊物,爱尔塞维亚(Elsevier)出版公司也是在生命科学文献界能够呼风唤雨的出版公司。

个人对这三份杂志的感觉是,全世界的科学家对《自然》要略微青睐一些,自然对发展中国家的投稿都比较友好,编辑会对来自英语国家的稿件进行英语修改和完善。编辑部的原则是科学第一,语言第二。《自然》杂志幅盖面很广,应该是龙头老大的地位。《科学》杂志也许一直会保留其风格,即在学术水平上跟《自然》争风斗艳,但是刊物还没有要扩张的迹象。

《科学》即是《自然》的对手,又和《自然》一起协手并肩统领报道人类科技的进步和发展的进程,比如当人类历史上耗资最大的人类基因测序工作完成后,《自然》发表了由Landers博士领导的学术界的人类基因测许结果;而《科学》则发表了由Venter博士领导的工业界完成的人类基因测序结果,可谓比翼双飞,也显示了英语在世界科学的领导地位。《细胞》杂志在生命科学界则是独树一旗,跟《自然》和《科学》的以短篇报道方式科学研究中的突破和进展不同之处是《细胞》的每篇文章都要求是长篇大论,文章必须要叙述一个完整的研究过程和结果,每期《细胞》的文章总数一般不超过15 篇。此外《细胞》跟其名一样,文章的角度也多从细胞生物学,分子生物学的手段和方法展开,相对来说,较少从分子遗传学,群体遗传学,化学生物学的角度出发。

这三份DJ学术期刊不仅是各大学和研究所的必定刊物,而且欧美大学许多教授,科研人员都自己定阅这些刊物,其中《科学》个人定阅价是140美元,《自然》是 199美元一年。像其他许多杂志一样,欧美杂志的做法是定阅者交的费用只是像证性的,杂志主要靠名气和发行量后面所带来的广告费挣钱维持生计,杂志越有名,发行量越大,越容易生存。但是像爱尔塞维亚(Elsevier) 这样拥有众多杂志的出版公司也往往表现出很强的拢断行为,曾几何时,以波士顿地区哈佛麻省理工为代表的新英格兰派系的《细胞》杂志的学校、研究所定阅费(往往是图书馆的定阅杂志,全校师生可以下载文章)昂贵的连美国的公立大学都感到难以承受,以加州大学,密西根大学为首的几十所公立大学曾经罢投《细胞》杂志的稿件,以表达他们的不满,双方的挣执曾使牛气十足的《细胞》杂志降下身段接受发展中国家科学家的稿件,中国也有了事隔二十几年得以重返《细胞》杂志的大事记!

这几份牛气的DJ学术的垄断行为和昂贵的订阅费也引起了一些科学家的烦感,终于有一些人站了出来,他们决心创办一份真正免费的生命科技杂志,Plos(Public Library of Science)就是这样诞生的产物,它是完全开方的,免费阅读, 免费打印!只有发表是收费的,多完美的主意!记得几年前我在加州大学旧金山分校做博后时,有一天所里来了一个讲座,就是关于Plos杂志,题目就是介绍一份全新的杂志Plos-公共科学杂志,当时听讲的人并不多,比起一般的学术讲座真可谓廖廖无几,主持人开场白介绍-讲演者也是一位优秀的科技工作者,她在博士博后期间有7篇论文发表,文章包括《Nature》,《Gene Development》《JBC》,《Molecular Cell》等,后来她加入了《自然》杂志的编辑行业。她讲到在她做编辑的时候才感觉到,很多发展中国家的大学的财力无力订阅全《自然》家族的杂志,因为稿费昂贵的原因,一些优秀的稿件也不能送到《自然》这样的DJ刊物,这种情况被诺贝尔奖获得者NIH前院长Harold E. Varmus,博士也知道了,他和斯坦福大学的生化教授,基因芯片技术的殿基人之一Patrick O. Brown,博士,以及加州大学伯克莱分校的遗传学教授Michael B. Eisen博士共同发起创办了一份属于大众的科学杂志,真正意义上的免费杂志!这样2000年10月Plos终于诞生了。如果你能细看一看Plos杂志的核心原则,就就会明白它是一份百分之百的大众的科学学书杂志!对于发展中国家,Plos给予了最无私的优惠政策:

可喜的是Plos杂志今天已成为了仅次于《Nature》,《Science》和《Cell》的有极大影响力的刊物,并且成为了拥有Plos-one和Plos生物,医学,遗传学,计算生物,病原学,热带医学7个成员的大家庭, 虽然美国科学院院刊(PNAS)和少数几份杂志也是免费的,但都没有Plos这样有高的引用率和影响力。

《Plos》杂志的成功和贡献再一次告诉我们,发展科学技术一定要有一套体系,从科研基金的建立和管理,到建立世界顶尖大学及研究所,特别是最后一个环节-发表科学技术成果的平台和媒体-科技杂志,每一样都极其重要!中国以人数众多的科技人才,庞大的接受了西方教育的海外人才库和飞速发展的经济为后盾,中国成为世界科技大国和强国的现实只是时间问题,要想在这个问题上不走弯路,早日实现这一目标。创办一份成功的类似于《自然》或《Plos》这样的科技杂志是比不可少的,也是绝对需要的。

1、《细胞》(Cell)《细胞》(Cell)是美国爱思维尔(Elsevier)出版公司旗下的细胞出版社(Cell Press)发行的关于生命科学领域最新研究发现的杂志。能够在《Cell》杂志上发表学术论文,是生命科学研究者孜孜以求的目标,也是评选诺贝尔奖、竞选院士、展示大学和科研机构研究实力的重要依据。2、《自然》(Nature)《自然》(Nature)是英国自然出版集团发行的世界上历史悠久的、最有名望的科学杂志之一,是科学界普遍关注的、国际性、跨学科的周刊类科学杂志。《自然》报道科学世界中的重大发现、重要突破为使命,同时也提供快速权威的、有见地的新闻,还有科学界和大众对于科技发展趋势的见解的专题。要求科研成果新颖,引人注意,而且该项研究看来在该领域之外具有广泛的意义,无论是报道一项突出的发现,还是某一重要问题的实质性进展的第一手报告,均应使其他领域的科学家感兴趣。3、《科学》(Science)《科学》(Science)是美国最大的科学团体“美国科学促进会(AAAS)”的官方刊物,属于综合性科学杂志,《科学》是发表最好的原始研究论文、以及综述和分析当前研究和科学政策的同行评议的期刊之一。它的科学新闻报道、综述、分析、书评等部分,都是权威的科普资料,该杂志也适合一般读者阅读。“发展科学,服务社会”是AAAS也是《science》杂志的宗旨。4、《美国科学院院报》(PNAS)《美国科学院院报》(PNAS)与《Cell》、《Nature》、《Science》齐名,被引用次数最多的综合学科文献之一。自1914年创刊至今,PNAS提供具有高水平的前沿研究报告、学术评论、学科回顾及前瞻、学术论文以及美国国家科学学会学术动态的报道和出版。PNAS提供具有高水平的前沿研究报告、学术评论、学科回顾及前瞻、学术论文以及美国国家科学学会学术动态的报道和出版。PNAS收录的文献涵盖医学、化学、生物、物理、大气科学、生态学和社会科学等。
