    Comment on ``Periodic wave functions and number of extended states in random dimer systems'

    There are no periodic wave-functions in the RDM but close to the critical energies there exist periodic envelopes. These envelopes are given by the non-disordered properties of the system.Comment: RevTex file, 1 page, Comment X. Huang, X. Wu and C. Gong, Phys. Rev. B 55, 11018 (1997

    Generalized reduction criterion for separability of quantum states

    Full text link
    A new necessary separability criterion that relates the structures of the total density matrix and its reductions is given. The method used is based on the realignment method [K. Chen and L.A. Wu, Quant. Inf. Comput. 3, 193 (2003)]. The new separability criterion naturally generalizes the reduction separability criterion introduced independently in previous work of [M. Horodecki and P. Horodecki, Phys. Rev. A 59, 4206 (1999)] and [N.J. Cerf, C. Adami and R.M. Gingrich, Phys. Rev. A 60, 898 (1999)]. In special cases, it recovers the previous reduction criterion and the recent generalized partial transposition criterion [K. Chen and L.A. Wu, Phys. Lett. A 306, 14 (2002)]. The criterion involves only simple matrix manipulations and can therefore be easily applied.Comment: 17 pages, 2 figure

    The Newton-Wu conditions for the cancellation of quadratic divergences in a class of two-Higgs-doublet models are analyzed as to how they may be satisfied with a typical extension of the Standard Model of particle interactions.Comment: 5 pages, no figur

    5D-Black Hole Solution in Einstein-Yang-Mills-Gauss-Bonnet Theory

    Full text link
    By adopting the 5D version of the Wu-Yang Ansatz we present in closed form a black hole solution in the Einstein-Yang-Mills-Gauss-Bonnet (EYMGB) theory. In the EYM limit, we recover the 5D black hole solution already known.Comment: 5 pages, no figure

    Correcting Things as Correcting Feelings: A Phenomenological Study of Wang Yang-ming’s Doctrine of Ge-Wu

    Get PDF
    This article is designed to offer a phenomenological reading of Wang Yang-ming’s (王陜明) doctrine of ge-wu (栌物), which, as a part of Wang radical reading of The Great Learning (Da-Xue 性歞), distinguishes his doctrine from that of Zhu Xi (朱ç†č). Wang argues that ge-wu, as rectifying things, is the same process with the act of cheng-yi (èȘ æ„), in which yi (意) and wu (物) form a relation of intentionality in Edmund Husserl’s sense. Since for Wang, what can be made sincere are emotional yi such as liking and disliking, Husserl\u27s phenomenology on emotional intentionality will be used in this article. The emotional intentionality is the unity of emotional noeses and valued noemata. For Wang, ge-wu is to change a wu improperly valued into a proper one, which is the same process of rectifying an immoral yi into a moral one

    K.C. Wu Collection

    Get PDF
    K.C. Wu (1903-1984) served as mayor of several Chinese cities during the 1930s and 1940s and then in December 1949 was appointed Governor of Taiwan by Chiang Kai-shek. Wu emigrated to the United States in 1954. Wu joined the faculty of Armstrong from 1966 to 1973. The collection consists of biographical information, manuscripts mainly of The Chinese Heritage (1982), lecture notes, clippings and information on his lawsuit with the National Endowment for the Humanities in 1972. Also Wu\u27s collection of Chinese history books.https://digitalcommons.georgiasouthern.edu/finding-aids-lane/1030/thumbnail.jp

    Manifestly Covariant Actions for D=4 Self-Dual Yang-Mills and D=10 Super-Yang-Mills

    Get PDF
    Using an infinite number of fields, we construct actions for D=4 self-dual Yang-Mills with manifest Lorentz invariance and for D=10 super-Yang-Mills with manifest super-Poincar\'e invariance. These actions are generalizations of the covariant action for the D=2 chiral boson which was first studied by McClain, Wu, Yu and Wotzasek.Comment: Removed an unnecessary term from the super-Yang-Mills action and added a reference. 12 pages harvmac te

    Effects of Warm Up Intensity on Factors Related to Subsequent Performance of Submaximal Exercise

    Get PDF
    Introduction: Athletes often warm up (WU) prior to exercise to improve performance. However, there are no clear directives regarding the intensity of the WU that is most effective in improving physiological responses related to enhanced aerobic performance. Methods: Nine college-aged men (age, ht, mass, 20.6 yr, 1.7 m, 84.8 kg, respectively) performed WU of varying intensities, 60% ventilatory threshold (VT), 100%VT, and 120%VT prior to performing 5 min of steady state exercise at 80%VT on a cycle ergometer. O2 deficit, RPE, steady state heart rate (HRss), and steady state VO2 (VO2ss) were measured during the exercise bout. Results: There was a significant decrease in O2 deficit as WU intensity increased ((2,9)= 9.15, p = .002, 2=0.53) with the deficit being lowest after WU at 120%VT. RPE were significantly lower after WU at 120%VT than both 60% and 100%VT (=(2,9)=6.88, p=.007, 2=0.46). However, WU intensity did not significantly affect either HRss (F(2,9)=0.48, p=0.63) or VO2ss (F(2,9)=1.10, p=0.36) during the exercise bout. Conclusion: The findings suggest that a higher intensity WU improves factors related to improved aerobic performance, i.e. decreased O2 deficit and RPE, without adversely affecting factors that could lead to a decline in performance, i.e. increased HRss and VO2ss
