TL;DR: A series of difunctional fluorene-based benzoxazine monomers were synthesized from the reaction of 9,9-bis-(4-hydroxyphenyl)-fluorene with formaldehyde and primary amines including aniline, o -toluidine, n -butylamine, and n -octylamine as discussed by the authors.

TL;DR: A decentralized fault-tolerant control system is proposed for near-space vehicle (NSV) attitude dynamics with a focus on the accommodation for actuator faults, control surface damage, uncertainties, and the resulting disturbances of the NSV.
Abstract: In this paper, a decentralized fault-tolerant control (FTC) system is proposed for near-space vehicle (NSV) attitude dynamics. First, NSV reentry attitude dyna mic models with an uncertainty, actuator failure models, and a control surface damage model are described. Next, a new local fault identification algorithm is proposed to iden tify different types of actuator faults, which is based on multiobserver techniques. The local fault identification is constituted by a fault detection observer, fault parameter identification observers, and a decision-making mechanism. Then, a global adaptive sliding-mode observer is used to design the command filter backstepping fault- tolerant controller. Our focus is on the accommodation for actuator faults, control surface damage, uncertainties, and the resulting disturbances of the NSV. Finally, simulation results are given to demonstrate the effectiveness and poten tial of the proposed FTC scheme.

TL;DR: It is found that the release of doxorubicin (DOX) from the functional carrier could be triggered by both pH value and near-infrared (NIR) radiation.
Abstract: To integrate photothermal therapy (PTT) with chemotherapy for improved antitumor efficiency, we designed a novel multifunctional composite by attaching CuxS nanoparticles onto the surface of Y2O3:Yb/Er hollow spheres through a combined coprecipitation and subsequent hydrothermal route. By altering the initial pH values for the synthesis of precursors, the size and structure properties of the final composites can controllably be tuned. The conjugated folic acid (FA) makes the composite recognize the targeted cancer cells and the attached CuxS nanoparticles endow the composite with photothermal function. It is found that the release of doxorubicin (DOX) from the functional carrier could be triggered by both pH value and near-infrared (NIR) radiation. In particular, both PTT and chemotherapy can be simultaneously driven by 980 nm laser irradiation. The synergistic therapeutic effect based on PTT and chemotherapy can lead to low in vitro viability of 12.9% and highly strong inhibition of animal H22 tumor in v...

TL;DR: In this paper, the hydrodynamic problem of a two-dimensional asymmetrical wedge entering calm water obliquely at constant speed is analyzed based on the velocity potential theory, and the gravity effect on the flow is ignored based upon the assumption that the ratio of the entry speed to the acceleration due to gravity is much larger than the time scale of interest.
