Peroxynitrite (ONOO-) is an important species involved in many physiopathological processes. Progresses have been made in developing novel fluorescent probes to detect peroxynitrite with relatively high sensitivity and specificity. Herein, we report the synthesis, characterization and biological applications of a new boronate-based fluorescent probe, 4-MB. The studies showed that 4-MB exhibits a dual ratiometric and calorimetric response toward peroxynitrite due to ONOO--triggered oxidative reaction. A possible mechanism of the oxidation reaction was proposed and the reaction product was isolated and characterized using different spectroscopic methods. We have thoroughly demonstrated the utility of 4-MB for intracellular peroxynitrite imaging. Further, we showed that 4-MB can be potentially employed to visualize exogenous and endogenous peroxynitrite in RAW264.7 macrophages, EAhy926 cells, zebrafish and in live tissues from a high-fat diet-induced obese mouse model.
Enhancement of resistive switching properties in nitride based CBRAM device by inserting an Al2O3 thin layer

In this letter, we propose a method to enhance resistive switching properties in SiCN-based conductive-bridge resistive switching memory (CBRAM) devices by inserting a thin Al2O3 layer between the SiCN resistive switching layer and the TiN bottom electrode. Compared with the Cu/Ta/SiCN/TiN single-layer device, the Cu/Ta/SiCN/Al2O3/TiN double layer device exhibits uniform resistive switching, long stable endurance cycles (>1.6 x 10(4)), and stable retention (10(4)s) at 125 degrees C. These substantial improvements in the resistive switching properties are attributed to the location of the formation and rupture of conductive filaments that can be precisely controlled in the device after introducing the Al2O3 layer. Moreover, a multilevel resistive switching characteristic is observed in the Cu/Ta/SiCN/Al2O3/TiN double layer CBRAM device. The distinct six-level resistance states are obtained in double layer devices by varying the compliance current. The highly stable retention characteristics (>10(4)) of the Cu/Ta/SiCN/Al2O3/TiN double layer device with multilevel resistance states are also demonstrated. Published by AIP Publishing.
The effect of device electrode geometry on performance after hot-carrier stress in amorphous In-Ga-Zn-O thin film transistors with different via-contact structures

In this letter, the effects of hot carriers on amorphous In-Ga-Zn-O thin film transistors (TFTs) of different geometric structures were investigated. Three types of via-contact structure TFTs are used in this experiment, defined as source-drain large (SD large), source-drain normal (SD normal), and fork-shaped. After hot-carrier stress, the I-V curves of both SD normal and fork-shaped TFTs with U-shaped drains show a threshold voltage shift along with the parasitic transistor characteristic in the reverse-operation mode. Asymmetrical degradation is exhibited in an ISE-TCAD simulation of the electric field, which shows the distribution of hot electrons injected into the etch-stop layer below the redundant drain electrode.

This work devises a maximum-margin sparse coding algorithm, jointly considering reconstruction loss and hinge loss in the model. The sparse representation along with maximum-margin constraint is analogous to kernel trick and maximum-margin properties of support vector machine (SVM), giving a base for the proposed algorithm to perform well in classification tasks. The key idea behind the proposed method is to use labeled and unlabeled data to learn discriminative representations and model parameters simultaneously, making it easier to classify data in the new space. We propose to use block coordinate descent to learn all the components of the proposed model and give detailed derivation for the update rules of the model variables. Theoretical analysis on the convergence of the proposed MMSC algorithm is provided based on Zangwill's global convergence theorem. Additionally, most previous research studies on dictionary learning suggest to use an overcomplete dictionary to improve classification performance, but it is computationally intensive when the dimension of the input data is huge. We conduct experiments on several real data sets, including Extended YaleB, AR face, and Caltech101 data sets. The experimental results indicate that the proposed algorithm outperforms other comparison algorithms without an over-complete dictionary, providing flexibility to deal with high-dimensional data sets.
