Fuzzy Adaptive Finite-Time Resilient Control Against Unknown False Data Injection Attacks for MIMO Nonlinear Switched Systems With Unknown Dead Zone.

This article studies the finite-time adaptive resilient control problem for MIMO nonlinear switched systems with the unknown dead zone. The sensors of the controlled systems suffer from unknown false data injection (FDI) attacks so that all states cannot be directly applied to the design process of the controller. To address this negative impact of FDI attacks, a new coordinate transformation is designed in control design.

Influence of Electrode Structure on Performance of Laser Direct Writing Cu-PI Flexible Humidity Sensor.

Electrode structure is an essential factor affecting the performance of flexible humidity sensors. In this study, Cu and Cu2 + 1O electrodes were printed by the one-step method using laser direct writing technology to reduce the nano-CuO ink on flexible substrate PI and to be used for a humidity sensor. The resistance of the humidity sensors with nine various electrode structures was measured under the relative humidity (RH) of 16-78%.

Rapid construction of indole-fused 8-10 membered lactones a tandem reaction.

An intramolecular anaerobic Mukaiyama hydration-initiated tandem reduction/condensation/acyl migration/aromatization reaction was developed, which enabled the rapid construction of indole-fused 8-10 membered lactones starting from cyclic 2-allyl-2-(2-nitrophenyl)-1,3-diketones. A nitro substituent in the substrates acted as both an oxygen source in the Mukaiyama hydration step and a nitrogen source in a tandem indole ring construction step. Our reaction features mild conditions, atom economy, and inexpensive reagents and it can be conveniently scaled up to a gram scale in modest yields.

[Cement augmented pedicle screw combined with vertebroplasty for the treatment of Kümmell's disease with type Ⅲ].

Objective: To explore clinical effect of cement-augmented pedicle screw combined with vertebroplasty in treating Kümmell disease with type Ⅲ.

Methods: From January 2015 to December 2018, 37 patients with type Ⅲ Kümmell disease were retrospectively analyzed, including 11 males and 26 females, aged from 61 to 84 years old with an average of (68.6±4.

[Application of PHILOS plate through mini-open deltoid-splitting approach for the treatment of proximal humeral fractures].

Objective: To study clinical effects of PHILOS (proximal humeral internal locking system) plates through mini-open deltoid-splitting approach for the treatment of proximal humeral fractures.

Methods: From March 2006 to August 2010, 22 patients with proximal humeral fractures were treated with PHILOS plates through mini-open deltoid-splitting approach. According to Neer classification, 6 cases were type II, 15 cases were type III and 1 case was type IV.
