Metal–organic framework-based hybrids with photon upconversion Upconversion materials (UCMs) featuring an anti-Stokes type emission establish them as an important category of photoluminescent materials. Metal–organic frameworks (MOFs) are rapidly gaining prominence as a class of versatile materials with favourable physical and chemical properties, including high porosity, controllable pore size, flexible design, and diverse functional sites.

AbstractThis semester-long qualitative case study, spanning 4 months, focused on an English reading course in which 20 university English-as-a-foreign-language readers were instructed to engage in web-based collaborative learning outside of class. The study drew on data resources including interviews with students, field notes on their web-based collaborative learning practices, and students’ written reflections.

Figure 4Two-point correlation functions of the S-matrix elements for a≠b in the frequency ranges indicated in the panels. Shown are the results for the cavity SB1 (black) and SB2 (red), the exact analytical results deduced from Eq. (1) with Ĥ replaced by Ĥ1→2(ξ) (turquoise), and the results obtained from Monte Carlo simulations for the S matrix, given by Eq. (1), with Ĥ replaced by Ĥ0→2(λ) (orange).

AbstractPolymerization in living systems has become an effective strategy to regulate cell functions and behavior. However, the requirement of high concentrations of monomers, the existence of complicated intracorporal interferences, and the demand for extra external stimulations hinder their further biological applications.

Abstract:Cloud manufacturing is characterized by large uncertainties and disturbances due to its networked, distributed, and loosely coupled features. To target the problem of frequent cloud resource node failure, this paper proposes (1) three resource substitution strategies based on node redundancy and (2) a new robustness analysis method for cloud manufacturing systems based on a combination of the complex network and multi-agent simulation.
