Based on a sample of (2712.4 ± 14.3) × 106 ψ(3686) events collected with the BESIII detector, a partial wave analysis of the decay $$ \psi (3686)\to \Lambda {\overline{\Sigma}}^0{\pi}^0 $$ + c.c. is performed to investigate Λ* and Σ* resonances in the $$ {\pi}^0{\overline{\Sigma}}^0 $$ and π0Λ invariant mass distributions. Significant contributions are found from the Λ(1405), Λ(1520), Λ(1600), Λ(1670), Λ(1690), Λ(1800), Λ(1890), Λ(2325), Σ(1385), Σ(1660), Σ(1670), Σ(1750), and Σ(1910). The masses, widths, and production branching fractions for each component are determined. In addition, the branching fraction of $$ \psi (3686)\to \Lambda {\overline{\Sigma}}^0{\pi}^0 $$ + c.c. is measured to be (1.544 ± 0.013 ± 0.071) × 10−4 for the first time, where the first uncertainty is statistical and the second systematic.

Solid-liquid-gas reactions are ubiquitous. An understanding of how gases influence the reactions at the nanoscale is significant for achieving the enhanced triple-phase reactions. Here, we report a real-time observation of the accelerated etching of gold nanorods with oxygen nanobubbles in aqueous hydrobromic acid using liquid cell transmission electron microscopy (TEM). Our observation reveals that when an oxygen nanobubble is close to a nanorod below the critical distance (~1nm), the local etching rate is significantly enhanced with over an order of magnitude faster. Molecular dynamics simulations results show that the strong attractive van der Waals interaction between the gold nanorod and oxygen molecules facilitates the transport of oxygen through the thin liquid layer to the gold surface and thus plays a crucial role in increasing the etching rate. This result sheds light on the rational design of solid-liquid-gas reactions for enhanced activities. © 2020, CC BY.

Ga2O3 doping and vacancy effect in KNN-LT lead-free piezoceramics

Frontiers of Materials Science 2017年第4期11卷 344-352页

Ga2O3 was doped into 0.95（K0.48Na0.52）NbO3-0.05LiTaO3 （KNN-LT） cera- mics and its influences on the sintering behavior, phase structure and electrical properties of ceramics were studied. Firstly, SEM observation exhibits that more and more glass phase appears in ceramics with the gradual addition of Ga2O3, which determines the continuous decrease in sintering temperatures. And the addition of Ga2O3 is also found to increase the orthorhombic-tetragonal transition temperature （To-T） of system to a higher level. Secondly, both the density and the coercive field （Ec） of ceramics increase firstly and then decrease with increasing the Ga2O3 content, and the KNN-LT-xGa sample at x = 0.004 shows a pinched P-E hysteresis loop. Finally, the impedance characteristics of KNN-LT-xGa ceramics were investigated at different temperatures, revealing a typical vacancy related conduction mechanism. This work demonstrates that Ga2O3 is a good sintering aid for KNN-based ceramics, and the vacancy plays an important role in the sintering and electrical behaviors of ceramics.

In this paper, the fuzzy active disturbance rejection controller is developed to control a quadrotor with external disturbance and actuator fault, while the state observer is designed to detect the actuator fault, and based on the fault detection information, the control allocation algorithm is proposed to achieve the aim of fault-tolerant control and performance optimization control. Finally, some simulation results are demonstrated to verify the effectiveness of the developed fault-tolerant control scheme.

The oxygen ion (O^2-) loss effect during resistive switching (RS) cycles will inevitably lead to endurance degradation or even failure in oxide-based memristive devices. In this Letter, we propose an effective way to recover the cycling-induced endurance failed HfO_x based memristive devices by utilizing oxygen plasma treatment (OPT). In the as-fabricated Pt/HfO_x/Pt devices, a negative SET event is observed after consecutive normal RS cycles and eventually triggers endurance failure. The appearance of the intermediate resistance state at the initial stage of the negative SET cycle indicates a prominent reduction of the migration barrier of O^2-, which accounts for the occurrence of negative SET after increasing cycles. Then, we recover the devices from endurance failure by moderate OPT, which can supply the available O^2- in RS cycles. More importantly, the first recovered devices after endurance failure can be recovered again through OPT, which better proves the validity of the recovery method. This study could provide an effective approach for understanding and addressing the cycling-induced endurance failure issue in oxide-based memristive devices. © 2019 Author(s).

The non-local means (NLM) algorithm computes the pixel similarity using a globally-fixed average patch and research window. Few studies have attempted to find a method of adaptively choosing a patch shape and research window size based on local characteristics. To exploit the local characteristics effectively, we propose an adaptive directional non-local means algorithm with size-adaptive search window (ADNLM-AW). The proposed algorithm first computes the direction of each pixel and partitions the entire image region into three classes. Subsequently, the directional rectangular patches are rotated to coincide with the direction of the texture and the search windows are adaptively adjusted to match the local characteristics of the regions. The experimental results show that the proposed algorithm outperforms other current NLM algorithms in terms of visual quality and peak signal to noise ratio (PSNR).
