    Brain Networks, Structural Realism, and Local Approaches to the Scientific Realism Debate
    Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences 64 1-10. 2017.
    We examine recent work in cognitive neuroscience that investigates brain networks. Brain networks are characterized by the ways in which brain regions are functionally and anatomically connected to one another. Cognitive neuroscientists use various noninvasive techniques (e.g., fMRI) to investigate these networks. They represent them formally as graphs. And they use various graph theoretic techniques to analyze them further. We distinguish between knowledge of the graph theoretic structure of su…Read more

    Knowledge, certainty, and skepticism: A cross-cultural study
    In Stephen Stich, Masaharu Mizumoto & Eric McCready (eds.), Epistemology for the rest of the world, Oxford University Press. pp. 187-214. 2018.
    We present several new studies focusing on “salience effects”—the decreased tendency to attribute knowledge to someone when an unrealized possibility of error has been made salient in a given conversational context. These studies suggest a complicated picture of epistemic universalism: there may be structural universals, universal epistemic parameters that influence epistemic intuitions, but that these parameters vary in such a way that epistemic intuitions, in either their strength or propositi…Read more

    Evolution of the Valley Position in Bulk Transition-Metal Chalcogenides and Their Monolayer Limit
    with H. Yuan, Z. Liu, G. Xu, B. Zhou, S. Wu, D. Dumcenco, Y. Zhang, S. K. Mo, P. Dudin, V. Kandyba, M. Yablonskikh, A. Barinov, Z. Shen, S. Zhang, Y. Huang, X. Xu, Z. Hussain, H. Y. Hwang, Y. Cui, and Y. Chen
    © 2016 American Chemical Society.Layered transition metal chalcogenides with large spin orbit coupling have recently sparked much interest due to their potential applications for electronic, optoelectronic, spintronics, and valleytronics. However, most current understanding of the electronic structure near band valleys in momentum space is based on either theoretical investigations or optical measurements, leaving the detailed band structure elusive. For example, the exact position of the conduc…Read more
  • Lithium-oxygen cells are a promising power source, and carbons are an attractive non-metal catalyst for air electrodes. To improve the electrochemical performance, various carbons are heated in an inert atmosphere. It is found that heat treatment at 900 C can differently improve the electrochemical performance of multiwalled carbon nanotubes, acetylene carbon black and activated carbon, but the improvement of CNTs is the most obvious. After heat treatment, the peak current density of the oxygen …Read more
