Low-temperature fabrication of black-phase CsPbI3 perovskite films is first demonstrated by using diphenylphosphinic chloride additive under 30-50 degrees C, arising from the steric effect and chloride insertion ***-area high-quality all-inorganic perovskite films with fewer defects enhanced crystallographic orientation, and excellent environmental stability is *** record performances are demonstrated for flexible wearable photodetectors with a responsivity of 42.1 A W-1, a detectivity of 1.3 x 1014 Jones, high-fidelity image, photoplethysmography sensor functions, and high mechanical stability. Flexible wearable optoelectronic devices fabricated from organic-inorganic hybrid perovskites significantly accelerate the development of portable energy, biomedicine, and sensing fields, but their poor thermal stability hinders further applications. Conversely, all-inorganic perovskites possess excellent thermal stability, but black-phase all-inorganic perovskite film usually requires high-temperature annealing steps, which increases energy consumption and is not conducive to the fabrication of flexible wearable devices. In this work, an unprecedented low-temperature fabrication of stable black-phase CsPbI3 perovskite films is demonstrated by the in situ hydrolysis reaction of diphenylphosphinic chloride additive. The released diphenyl phosphate and chloride ions during the hydrolysis reaction significantly lower the phase transition temperature and effectively passivate the defects in the perovskite films, yielding high-performance photodetectors with a responsivity of 42.1 A W-1 and a detectivity of 1.3 x 1014 Jones. Furthermore, high-fidelity image and photoplethysmography sensors are demonstrated based on the fabricated flexible wearable photodetectors. This work provides a new perspective for the low-temperature fabrication of large-area all-inorganic perovskite flexible optoelectronic devices.

In this paper, a CPA （Control Performance Assessment） approach is proposed for output B-spline PDF dynamic stochastic system in the uncertainty sense. This article focus on A new entropy concept, which is similar to Shannon entropy, has been introduced to characterize the uncertainty of the stochastic variable of B-spline PDF dynamic stochastic system, and A normalized index , ηE , which derives from the entropy concept, presents as a criterion for assessing the performance of output B-spline PDF dynamic stochastic system subjected to mean constraint. The performance index ηE is attractive because it provides a measure of uncertainty for the stochastic system and whether the existing controller performed well or not in the entropy sense. A recursive algorithm based on Lyapunov method has been developed to design an efficient controller to minimize the entropy of the stochastic variable of the stochastic system with the mean constraint. At the end of this paper, a simulation example is incorporated to show the feasibility and effectiveness of proposal criterion.

In this paper, a new method is presented for identification of single-input single-output（SISO） nonlinear systems with long time delay. The proposed dynamic extreme learning machine（DELM） is different from extreme learning machine in that it adds adaptive delay parameters in the output layer of the network, and the delay parameter is optimized by use of particle swarm algorithm. The dynamic extreme learning machine has two main advantages: First, for any system, it needs only two input nodes. Second, it does not need to know the specific delay time. A pH neutralization process and a nonlinear dynamic system process are used to evaluate the performance of the proposed method. Simulation results demonstrate the effectiveness of the proposed identification algorithm for a class of nonlinear system with long time delay.

In this paper, an improved estimation of distribution algorithm（EDA） is proposed and applied to the identification of ARMA model parameters. The system parameter identification problem is transformed into the optimization problem in high dimensional parameter space. Based on the traditional EDA algorithm, the parameters of preliminary estimation and data selection are added to improve the speed of searching and optimization precision. Because the mean and the variance are not enough to describe the uncertainty of non-Gaussian system, the entropy is regarded as fitness value to achieve the parameter identification of non-Gaussian system. Finally, an example of improved EDA identification is given to illustrate the effectiveness of the proposed approach.

The special sections of volume target are observed with acoustic vector intensity according to the difference among their radiated-noise characteristics, then three sections are tracked with Kalman filtering, and target size is estimated. Simulation results indicate that in ideal condition three sections of a ship can be tracked and ship's size can be estimated even though one of three sections can not be observed.

为了防范人类生存危机,道德增强进入了科技伦理议程中。由于生物医学道德增强的诸多弊端,各种人工智能道德增强方案被陆续提出,分别为:人工智能作为人类道德决策的“替代者”“建议者”或“对话者”;“替代者方案”将导致道德消亡,阻碍道德进步,但适用于危急情境;“建议者方案”会损害能动者的能动性,固化其道德观念,但适用于日常决策;“对话者方案”能够帮助用户实现道德成长,但无法提供道德动力。混合式道德增强将各方案应用于不同场景,在紧急状态下调用“替代者”模式,在日常生活道德决策情境中唤醒“建议者”模式,在空闲时段进入“对话者”模式,兼顾三种方案优点又规避其缺陷。但混合式方案仍需要生物道德增强的辅助以提升用户道德动机,并被纳为义务性培训的一部分。
