Review of Particle Physics

Offering a unifying theoretical perspective not readily available in any other text, this innovative guide to econometrics uses simple geometrical arguments to develop students' intuitive understanding of basic and advanced topics, emphasizing throughout the practical applications of modern theory and nonlinear techniques of estimation. One theme of the text is the use of artificial regressions for estimation, reference, and specification testing of nonlinear models, including diagnostic tests for parameter constancy, serial correlation, heteroscedasticity, and other types of mis-specification. Explaining how estimates can be obtained and tests can be carried out, the authors go beyond a mere algebraic description to one that can be easily translated into the commands of a standard econometric software package. Covering an unprecedented range of problems with a consistent emphasis on those that arise in applied work, this accessible and coherent guide to the most vital topics in econometrics today is indispensable for advanced students of econometrics and students of statistics interested in regression and related topics. It will also suit practising econometricians who want to update their skills. Flexibly designed to accommodate a variety of course levels, it offers both complete coverage of the basic material and separate chapters on areas of specialized interest.

NUDGE: IMPROVING DECISIONS ABOUT HEALTH, WEALTH, AND HAPPINESS by Richard H. Thaler and Cass R. Sunstein Penguin Books, 2009, 312 pp, ISBN 978-0-14-311526-7This book is best described formally as a general explanation of and advocacy for libertarian paternalism, a term coined by the authors in earlier publications. Informally, it is about how leaders, systems, organizations, and governments can nudge people to do the things the nudgers want and need done for the betterment of the nudgees, or of society. It is paternalism in the sense that "it is legitimate for choice architects to try to influence people's behavior in order to make their lives longer, healthier, and better", (p. 5) It is libertarian in that "people should be free to do what they like - and to opt out of undesirable arrangements if they want to do so", (p. 5) The built-in possibility of opting out or making a different choice preserves freedom of choice even though people's behavior has been influenced by the nature of the presentation of the information or by the structure of the decisionmaking system. I had never heard of libertarian paternalism before reading this book, and I now find it fascinating.Written for a general audience, this book contains mostly social and behavioral science theory and models, but there is considerable discussion of structure and process that has roots in mathematical and quantitative modeling. One of the main applications of this social system is economic choice in investing, selecting and purchasing products and services, systems of taxes, banking (mortgages, borrowing, savings), and retirement systems. Other quantitative social choice systems discussed include environmental effects, health care plans, gambling, and organ donations. Softer issues that are also subject to a nudge-based approach are marriage, education, eating, drinking, smoking, influence, spread of information, and politics. There is something in this book for everyone.The basis for this libertarian paternalism concept is in the social theory called "science of choice", the study of the design and implementation of influence systems on various kinds of people. The terms Econs and Humans, are used to refer to people with either considerable or little rational decision-making talent, respectively. The various libertarian paternalism concepts and systems presented are tested and compared in light of these two types of people. Two foundational issues that this book has in common with another book, Network of Echoes: Imitation, Innovation and Invisible Leaders, that was also reviewed for this issue of the Journal are that 1 ) there are two modes of thinking (or components of the brain) - an automatic (intuitive) process and a reflective (rational) process and 2) the need for conformity and the desire for imitation are powerful forces in human behavior. …

Nudge: Improving Decisions about Health, Wealth, and Happiness

The recent advances in electrocatalysis for oxygen reduction reaction (ORR) for proton exchange membrane fuel cells (PEMFCs) are thoroughly reviewed. This comprehensive Review focuses on the low- and non-platinum electrocatalysts including advanced platinum alloys, core–shell structures, palladium-based catalysts, metal oxides and chalcogenides, carbon-based non-noble metal catalysts, and metal-free catalysts. The recent development of ORR electrocatalysts with novel structures and compositions is highlighted. The understandings of the correlation between the activity and the shape, size, composition, and synthesis method are summarized. For the carbon-based materials, their performance and stability in fuel cells and comparisons with those of platinum are documented. The research directions as well as perspectives on the further development of more active and less expensive electrocatalysts are provided.

Recent Advances in Electrocatalysts for Oxygen Reduction Reaction

Chip-based semi-packed gas chromatography (GC) columns coated with two kinds of mesoporous silica (MS) stationary phase have been explored and compared in this paper. For the first time, the influence of pore size of the stationary phase on the separation performance in a micro GC (μGC) column has been investigated. As has been demonstrated, full separation of heavy hydrocarbons (C 5 -C 10 ) can be achieved in both columns. Moreover, compared with stationary phase of smaller pores, that of bigger ones leads to obviously increased retention time of C9 and C10.

This paper reports a novel structure for monolithically integrated tri-axis high-shock accelerometer. All the tri-axial sensors feature ultra-high resonant frequencies, in which the Z-axis accelerometer is no longer a shorter board in design compared to its in-plane X- and Y-axis counterparts. The axially compressed/stretched tiny-beams are connected into Wheatstone-bridge for piezoresistive detection. Processed in ordinary (111) wafers, a low-cost high-yield non-SOI fabrication technique is developed in this study for manufacturing the complicated structure that consists of the axially deformed micro-beams. Being tested under 10000g high-shock acceleration, every of the three accelerometers exhibit 1–2μV/g sensitivity and about 1.5MHz resonant frequency.

This paper presents a novel anti-aliasing and self-clocking MASH-like electro-mechanical sigma-delta (ΣΔ) modulated MEMS disk resonant gyroscope with multi-bit force-balancing operation. The proposed technique allows extending the input signal range of a ΣΔM disk gyroscope beyond the limit imposed by single-bit stream operation. It effectively circumvents the chopping aliasing effect, which arises from interferences between the base-band signal spectrum and high frequency shaping-noise spectrum. This aliasing effect will lead to a reduction in the signal-to-noise ratio (SNR). Experimental results demonstrated that the proposed technique results in inherent stability and better performances when compared to a conventional approach.
