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

Mitochondria‐targeting small‐molecule NIR‐II fluorescent probes for imaging and treatment of tumor

This work reports a new method for real-time observing the growth process of metal-organic framework (MOF) nanocrystals under in-situ TEM (transmission electron microscopy). For MOF grown via gas-solid reaction, the ligands should be firstly vaporized and then introduced to the surface of metal-contained building-blocks for further gas-solid reaction. One challenge for in-situ TEM observing MOF growth process lies in that it is difficult to directly introduce the solid-state ligand molecules into micro-reactor. Herein, a micro-reactor integrated with SiN x observing windows, gas channel and micro-heater is fabricated for gas-solid growing MOF nanocrystals. The ligand molecules are previously encapsulated in mesoporous silica particles (MSNs) and then sustained released to avoid blocking the tiny capillary channel of the micro-reactor. By using the new method, dynamic process of vaporized H 3 BTC (trimesic acid) ligands reacting with ZnO nanowires for Zn 3 (BTC) 2 nanocrystal growing is successfully observed.

Gravimetric system based on resonant micro-cantilever had drawn significant attention in trace material detection. Adsorption quantity could be measured by the change of cantilever's resonant frequency, and phase-locked loop (PLL) was commonly used to keep the cantilever resonating. However, in the application of traditional PLL, we have to adjust parameters of the phase shifter to make sure the locked frequency matching with the cantilever's resonant frequency. In this manuscript, we promoted a frequency tracking system based on software phase-locked loop. Locked phase was calculated automatically, so the system could match with cantilevers of different resonant frequency, and no adjusting is need anymore. This system could combine with instruments based on frequency tracking and detection easily, not only limited to resonant cantilevers.

This article presents a tiny-size and high-performance thermal gas flow sensor with suspended <inline-formula> <tex-math notation="LaTeX">$\text{p}^{+}$ </tex-math></inline-formula>Si/<inline-formula> <tex-math notation="LaTeX">$\text{n}^{+}$ </tex-math></inline-formula>Si thermopile formed in an ordinary non-silicon-on-insulator (SOI) (111) silicon wafer. A front-side bulk micromachining technique is herein employed to form the proposed gas flow sensor without double-side fabrication process, wafer bonding, and cavity-SOI needed. To achieve high sensitivity and quick response time, the suspended single-crystalline <inline-formula> <tex-math notation="LaTeX">$\text{p}^{+}$ </tex-math></inline-formula>Si/<inline-formula> <tex-math notation="LaTeX">$\text{n}^{+}$ </tex-math></inline-formula>Si thermocouple which shows significantly higher Seebeck coefficient and lower noise compared to that of the traditional <inline-formula> <tex-math notation="LaTeX">$\text{p}^{+}$ </tex-math></inline-formula>polysilicon/<inline-formula> <tex-math notation="LaTeX">$\text{n}^{+}$ </tex-math></inline-formula>polysilicon thermocouple is first used to construct the flow sensor. And the fishbone-shaped suspended SiN dielectric membrane is designed to maximize the thermal resistance between the <inline-formula> <tex-math notation="LaTeX">$\text{p}^{+}$ </tex-math></inline-formula>Si heater and the silicon substrate, reducing heat dissipation from the <inline-formula> <tex-math notation="LaTeX">$\text{p}^{+}$ </tex-math></inline-formula>Si heater to the silicon substrate. In addition, using high heat-conductivity Au-film to connect the cold junction and the bulk silicon acting as a heat-sink not only increases the temperature difference between the hot junction and the cold junction but also reduces the complexity of the fabrication process. Thanks to the single-side micromachining process, the sensor chip size is as small as <inline-formula> <tex-math notation="LaTeX">$0.65\times0.60$ </tex-math></inline-formula> mm. Finally, the characterization of the fabricated gas flow sensor was evaluated, showing an ultrahigh normalization sensitivity of 5 V/sccm/W, a quick response time of 1.44 ms, and a minimum detectable flow velocity (MDFV) of 0.0083 sccm.
