A nitridation treatment technology with a urea/ammonia complex nitrogen source improved resistive switching property in HfO2-based resistive random access memory (RRAM). The nitridation treatment produced a high performance and reliable device which results in superior endurance (more than 10(9) cycles) and a self-compliance effect. Thus, the current conduction mechanism changed due to defect passivation by nitrogen atoms in the HfO2 thin film. At a high resistance state (HRS), it transferred to Schottky emission from Poole-Frenkel in HfO2-based RRAM. At low resistance state (LRS), the current conduction mechanism was space charge limited current (SCLC) after the nitridation treatment, which suggests that the nitrogen atoms form Hf-N-Ox vacancy clusters (V-o(+)) which limit electron movement through the switching layer.

A head-mounted display (HMD) apparatus includes an HMD device and a liquid crystal (LC) lens device. The HMD device has a light entering surface for entrance of ambient light, and a light exit surface. The HMD device permits passage of the ambient light therethrough to form a real world image for an observer who wears the HMD apparatus, and generates and projects display light toward the light exit surface to form a computer-generated image for the observer. The LC lens device has an adjustable focal length and is disposed to change convergence of the ambient light and the display light from the HMD device, so as to correct vision of the observer.

645-GHz signal generation with a harmonic oscillator based on a 250-nm InP heterojunction bipolar transistor technology is demonstrated. The oscillator is based on the common-base cross-coupled topology, generating a second harmonic signal through the push-push operation. The fabricated oscillator exhibits oscillation frequencies ranging from 561.5 to 645.1 GHz with bias variation. The measured peak output power is -17.4 dBm with a dc power dissipation of 49.3 mW (dc-to-RF efficiency of 0.04%). Additionally, terahertz imaging was successfully demonstrated with the developed oscillator employed as a signal source.

A display panel includes a substrate, and a pixel array and a gate driving circuit. The gate driving circuit provides gate driving signals to the pixel array, and includes shift registers, wherein each shift register includes a voltage providing unit, a first driving transistor, a voltage transmitting unit and a second driving transistor. The voltage providing unit receives a setting signal and a system high voltage to provide a first terminal voltage. The first driving transistor receives a first clock signal and the first terminal voltage to provide a first gate driving signal. The voltage transmitting unit receives the first gate driving signal to provide a second terminal voltage. The second driving transistor receives a second clock signal and the second terminal voltage to provide a second gate driving signal. Therefore, the influence caused by large difference of driving capabilities of the first and the second driving transistor is avoided.

The RNA chaperone Hfq is involved in the riboregulation of diverse genes via small RNAs. Recent studies have demonstrated that Hfq contributes to the stress response and the virulence of several pathogens, and the roles of Hfq vary among bacterial species. Here, we attempted to elucidate the role of Hfq in Acinetobacter baumannii ATCC 17978. In the absence of hfq, A. baumannii exhibited retarded cell growth and was highly sensitive to environmental stress, including osmotic and oxidative pressure, pH, and temperature. Compared to the wild-type, the Hfq mutant had reduced outer membrane vesicles secretion and fimbriae production as visualized by atomic force microscopy. The absence of hfq reduced biofilm formation, airway epithelial cell adhesion and invasion, and survival in macrophage. Further, the hfq mutant induced significantly higher IL-8 levels in airway epithelial cells, which would promote bacterial clearance by the host. In addition to results similar to those reported for other bacteria, our findings demonstrate that Hfq is required in the regulation of the iron-acquisition system via downregulating the bauA and basD genes, the stress-related outer membrane proteins carO, A1S_0820, ompA, and nlpE, and the stress-related cytosolic proteins uspA and groEL. Our data indicate that Hfq plays a critical role in environmental adaptation and virulence in A. baumannii by modulating stress responses, surface architectures, and virulence factors. This study is the first to illustrate the functional role of Hfq in A. baumannii.
