Electrochromic smart windows are promising for building energy savings due to their dynamic regulation of the solar spectrum. Restricted by materials or traditional complementary device configuration, precisely and independently controlling of visible (VIS) and near‐infrared (NIR) light is still on the drawing board. Herein, a novel Zn2+ electrochemically active Ce4W9O33 electrode is reported, which demonstrates three distinct states, including VIS and NIR transparent "bright and warm" state, VIS and NIR opaque "dark and cool" state, VIS transparent and NIR opaque "bright and cool" state. A dual‐operation mode electrochromic platform is also presented by integrating Ce4W9O33/NiO complementary device and Zn anode‐based electrochromic device (Ce4W9O33/Zn/NiO device). Such a platform enables an added VIS opaque and NIR transparent "dark and warm" state, thus realizing four color states through individually controlling Ce4W9O33 and NiO electrodes, respectively. These results present an effective approach for facilitating electrochromic windows more intelligent to weather/season conditions and personal preferences. [ABSTRACT FROM AUTHOR]

Gromov proved a quadratic decay inequality of scalar curvature for a class of complete manifolds. In this paper, we prove that for any uniformly contractible manifold with finite asymptotic dimension, its scalar curvature decays to zero at a rate depending only on the contractibility radius of the manifold and the diameter control of the asymptotic dimension. We construct examples of uniformly contractible manifolds with finite asymptotic dimension whose scalar curvature functions decay arbitrarily slowly. This shows that our result is the best possible. We prove our result by studying the index pairing between Dirac operators and compactly supported vector bundles with Lipschitz control. A key technical ingredient for the proof of our main result is a Lipschitz control for the topological K‐theory of finite dimensional simplicial complexes. [ABSTRACT FROM AUTHOR]

Improving the quality of enterprise innovation is a key path to implementing the innovation‐driven development strategy and thus promoting high‐quality economic development. Using a sample of Chinese A‐share listed companies from 2011 to 2019, this paper empirically examines the impact of institutional investor shareholding (IIS) on corporate innovation quality. The study finds that (1) IIS has a significant effect on the quality of corporate innovation, and it can also improve the quality of corporate innovation by increasing corporate financial support and promoting the efficiency of corporate management. (2) Heterogeneous IISs have different impacts, with pressure‐defensive IIS contributing more significantly to the quality of corporate innovations than pressure‐sensitive IIS. (3) The internal and external environments play an important moderating role. External market competition incentives and supervision means play a positive moderating role; internal financing constraints and business risks play a negative moderating role.

This article adopts the extended transaction cost theory to analyze the entry mode choices of Chinese multinational enterprises and their effects on overseas business performance. Theoretical hypotheses, which are developed from the perspectives of asset specificity of parent companies and investment environment differences of host countries, are tested with sample data of 406 overseas subsidiaries of Chinese multinational enterprises from 2015 to 2017. The empirical results show that the overseas subsidiaries of Chinese multinational enterprises whose entry mode choices can be predicted by the extended transaction cost theory usually perform significantly better than those whose entry mode choices cannot be predicted by the extended transaction cost theory.

This article explores how the Belt‐and‐Road Initiative has affected the internationalization of Chinese multinational enterprises with a case study of China Railway Rolling Stock Corporation. It is found that the Belt‐and‐Road Initiative can be considered as part of China's integration with global production networks, which enhances the ownership, location and internalization advantages of Chinese multinational enterprises. In particular, the Belt‐and‐Road Initiative has had a positive impact on improving the innovation capability and firm performance of Chinese multinational enterprises through promoting R&D internationalization and strengthening the specialization of production.

The luminescent hydrogen‐bonded organic framework (HOF) based films have become one of the most remarkable materials for optical application, thus, developing facile synthesis methods and establishing multifunctional applications for HOF‐based luminescent materials are essential. Herein, a dual‐emitting Eu3+‐functionalized HOF hydrogel film (1) is fabricated successfully. 1 emits a blue‐green long afterglow when turning off the UV lamp, and the long afterglow lifetime gets to 1.99 s. 1 performs great selectivity, high sensitivity, and low detection limit toward ofloxacin and flumequine, and the sensing toward ofloxacin and flumequine is in accord with the chroma and ratio modes. The fluorescent response mechanisms of 1 toward ofloxacin and flumequine are investigated in depth, which are further utilized to build an anticounterfeiting platform with high‐level security. The film‐based anticounterfeiting platform can conduct information encryption on demand inline with different fluorescent responses and can also fetch specific information by controlling the long afterglow intensity and excited light. This study not only provides a representative case of the fabrication of dual‐emitting Eu3+‐functionalized HOF‐based hydrogel film but also opens the possibility of HOF‐based film as intelligent luminescent materials with multifunctionalities.

Fluorescent chemodosimeters based on small organic molecules are widely used in the detection of various analytes. However, chemodosimeters for metal ion detection are still limited to a few transition metals, such as HgII, CuII, FeIII, AuIII, etc. In this work, a fluorescent chemodosimeter of 5-chloro-7-phenyliminomethyl-8-hydroxyquinoline ( 2) for the detection of AlIII is reported. Chemodosimeter 2 exhibits a turn-on fluorescence response to AlIII owing to an AlIII-promoted hydrolysis of carbon-nitrogen double bonds. This reaction yielded a 1- Al complex, which exhibited high fluorescence emission at 487 nm based on inhibition of excited-state intramolecular proton transfer (ESIPT). Because of the specific catalytic ability of AlIII, the selectivity of 2 to AlIII is excellent both in aqueous solutions and in solid matrix. The fluorescence enhancement was as high as 582-fold and the turn-on fluorescence can be observed even by the naked eye upon an irradiation with a UV lamp. The detection limit of 2 for AlIII sensing is 54 nmol L−1 and the linear range is 0-50 μmol L−1. This work provides a new strategy for designing main-group-metal chemodosimeters based on small organic molecules. [ABSTRACT FROM AUTHOR]

The economic literature can help us find how to foster entrepreneurship in China in order to ensure a sustainable economic growth. Someone asked Confucius 'Why do you not take part in government?' The Master replied: 'The Book of History says, Oh! Simply by being a good son and friendly to his brothers, a man can exert an influence upon government.' In so doing a man is, in fact, taking part in government.' (Confucius, The Anaclets, II.21. Translated by D.C. Lau, 1979) Zeal without knowledge is the sister of folly.

Background: There is a great deal of interest in traditional Chinese medicine as a treatment for chronic cerebral circulation insufficiency (CCCI). In the present study, we evaluated the efficacy and safety of Yangxue Qingnao Granules (YXQNG) as a monotherapy in patients with CCCI. Methods: From July 2007 to May 2010, 273 patients with CCCI at nine centres in China were randomly assigned to receive either YXQNG with nimodipine placebo ( n= 140, 12 g/day) or nimodipine with YXQNG placebo ( n= 133, 30 mg/day) for 8 weeks. The primary end points after 8 weeks of treatment were changes from baseline in severity of headache, heavy-headed feeling, dizziness and sleep disorder. Results: The mean baseline levels of headache, heavy-headed feeling, dizziness and sleep disorder were comparable between the two groups. Both therapies significantly improved these symptoms after 8 weeks of treatment ( P < 0.001). Compared with nimodipine therapy, YXQNG resulted in similar reductions in these symptoms. No adverse effects were observed in the YXQNG group. Conclusions: These data demonstrate that YXQNG as a monotherapy were as effective as nimodipine monotherapy in improving the symptoms of CCCI. It is well-tolerated and may have an important place in the management of this condition. Whether a combination of these two medicines will increase therapeutic efficacy deserves further clinical investigation. [ABSTRACT FROM AUTHOR]
