TL;DR: This paper discusses various biosensors in detail, where the biosensor consists of bioelement and a sensor element, and the bioelement may be an enzyme, antibody, living cells etc., and the sensing element may be electric current, electric potential, and so on.
Abstract: This paper discusses various biosensors in detail, where the biosensor consists of bioelement and a sensor element. The bioelement may be an enzyme, antibody, living cells etc., and the sensing element may be electric current, electric potential, and so on. This survey initially introduces the basic concept of the biosensors. High-level overviews of different types of biosensors are given and the working principles, constructions, advantages and applications of many biosensors are also presented. In addition to these MEMS have given rise to a whole new class of biosensors which involve the transduction of mechanical energy and are based on mechanical phenomena.

TL;DR: The blockchain is a public ledger that works like a log by keeping a record of all transactions in chronological order, secured by an appropriate consensus mechanism and providing an immutable record.
Abstract: In 2008, the emergence of the blockchain as the foundation of the first-ever decentralized cryptocurrency not only revolutionized the financial industry but proved a boon for peer-to-peer (P2P) information exchange in the most secure, efficient, and transparent manner. The blockchain is a public ledger that works like a log by keeping a record of all transactions in chronological order, secured by an appropriate consensus mechanism and providing an immutable record. Its exceptional characteristics include immutability, irreversibility, decentralization, persistence, and anonymity.

TL;DR: An overview of this technology for the realization of security across distributed parties in an impregnable and transparent way is presented.
Abstract: The blockchain is emerging as one of the most propitious and ingenious technologies of cybersecurity In its germinal state, the technology has successfully replaced economic transaction systems in various organizations and has the potential to revamp heterogeneous business models in different industries Although it promises a secure distributed framework to facilitate sharing, exchanging, and the integration of information across all users and third parties, it is important for the planners and decision makers to analyze it in depth for its suitability in their industry and business applications The blockchain should be deployed only if it is applicable and provides security with better opportunities for obtaining increased revenue and reductions in cost This article presents an overview of this technology for the realization of security across distributed parties in an impregnable and transparent way

TL;DR: Smart health care can be implemented at all levels, starting from temperature monitoring for babies to tracking vital signs in the elderly, so that the conventional patient-doctor appointment has lost its effectiveness.
Abstract: The Internet-of-Things (IoT) has taken over the business spectrum, and its applications vary widely from agriculture and health care to transportation. A hospital environment can be very stressful, especially for senior citizens and children. With the ever-increasing world population, the conventional patient-doctor appointment has lost its effectiveness. Hence, smart health care becomes very important. Smart health care can be implemented at all levels, starting from temperature monitoring for babies to tracking vital signs in the elderly.

TL;DR: A smart consumer electronics solution to facilitate safe and gradual opening after stay-at-home restrictions are lifted and an Internet of Medical Things enabled wearable called EasyBand is introduced to limit the growth of new positive cases.
Abstract: COVID-19 (Corona Virus Disease 2019) is a pandemic, which has been spreading exponentially around the globe. Many countries adopted stay-at-home or lockdown policies to control its spreading. However, prolonged stay-at-home may cause worse effects like economical crises, unemployment, food scarcity, and mental health problems of individuals. This article presents a smart consumer electronics solution to facilitate safe and gradual opening after stay-at-home restrictions are lifted. An Internet of Medical Things enabled wearable called EasyBand is introduced to limit the growth of new positive cases by autocontact tracing and by encouraging essential social distancing.

TL;DR: This book by a teacher of statistics (as well as a consultant for "experimenters") is a comprehensive study of the philosophical background for the statistical design of experiment.
Abstract: THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

TL;DR: CACM is really essential reading for students, it keeps tabs on the latest in computer science and is a valuable asset for us students, who tend to delve deep into a particular area of CS and forget everything that is happening around us.
Abstract: Communications of the ACM (CACM for short, not the best sounding acronym around) is the ACM’s flagship magazine. Started in 1957, CACM is handy for keeping up to date on current research being carried out across all topics of computer science and realworld applications. CACM has had an illustrious past with many influential pieces of work and debates started within its pages. These include Hoare’s presentation of the Quicksort algorithm; Rivest, Shamir and Adleman’s description of the first publickey cryptosystem RSA; and Dijkstra’s famous letter against the use of GOTO. In addition to the print edition, which is released monthly, there is a fantastic website (http://cacm.acm. org/) that showcases not only the most recent edition but all previous CACM articles as well, readable online as well as downloadable as a PDF. In addition, the website lets you browse for articles by subject, a handy feature if you want to focus on a particular topic. CACM is really essential reading. Pretty much guaranteed to contain content that is interesting to anyone, it keeps tabs on the latest in computer science. It is a valuable asset for us students, who tend to delve deep into a particular area of CS and forget everything that is happening around us. — Daniel Gooch U ndergraduate research is like a box of chocolates: You never know what kind of project you will get. That being said, there are still a few things you should know to get the most out of the experience.
