We propose simple behavioral definitions of comparative uncertainty aversion for a single agent towards different sources of uncertainty. Our definitions allow for the comparison of utility curvature for different sources if the agent’s choices satisfy subjective expected utility towards each source. We discuss how our definitions can be applied to investigate ambiguity aversion in Klibanoff et...

Bi2Te3 thermoelectric materials are utilized for refrigeration for decades, while their application of energy harvesting requires stable thermoelectric and mechanical performances at elevated temperatures. This work reveals that a steady zT of ≈0.85 at 200 to 300 °C can be achieved by doping small amounts of copper iodide (CuI) in Bi2Te2.2Se0.8-silicon carbide (SiC) composites, where SiC nanodi...

Acknowledgments: This project was undertaken when Xiaolin Xing was visiting University of Pittsburgh and Harvard University in 2000. Xiaolin Xing is grateful to the two universities for using their resources and facilities. We thank the seminar participants in Nanyang Technological University and the Chinese University of Hong Kong for comments. We also thank two anonymous referees for helpful ...

ing this work to humans. First, we do not know whether the molar concentration of CD3 is similarly limiting for the expression of transgenic human TCRs. If CD3 is indeed limiting, then the enhanced expression and functionality we achieve by cotransfection of CD3 and TCRs may be accompanied by enhanced toxicity. Thus, enhanced expression may increase the risk of mispairing of endogenous and tran...

Ionic liquids such as 1,3-dialkylimidazolium salts make excellent catalysts and solvents for synthesis of dialkyl 2-(dialkoxyphosphoryl)-3-(1-oxo-1-H-phthalazin-2-yl)succinates from 2H-phthalazin-1-one, dialkyl acetylenedicarboxylates, and trialkyl phosphites. Under similar conditions, triphenyl phosphite led to dialkyl 2-(diphenoxyphosphoryl)-3-(1-oxo-1-H-phthalazin-2-yl)succinates. The ionic ...

Nonvolatile Logic-in-Memory Computing In article number 2200089, Chunxiang Zhu and co-workers propose demonstrate an electrochemical metallization memristor based on a solution-processed Pt/CuI/Cu structure. Owing to the efficient drift paths provided by Cu vacancies for cations in CuI, very small operating voltages are realized, contributing ultralow power consumption. Using CuI arrays, set of...
