It is known that light extraction efficiency (LEE) for AlGaN-based deep ultraviolet light-emitting didoes (DUV LEDs) can be enhanced by using truncated cone arrays with inclined sidewalls. In this work, the air-cavity-shaped sidewall applied and p-GaN layer at top of laterally over-etched so more escape paths are generated DUV LEDs. The experimental results manifest when compared LEDs only having sidewall, optical power 30% without sacrificing forward bias. because makes little effect on...

Recently, implicit neural representation (INR) has been applied to image compression. However, the rate-distortion performance of most existing INR-based compression methods is still obviously inferior state-of-the-art methods. In this paper, we propose an Enhanced Quantified Local Implicit Neural Representation (EQLINR) for by enhancing utilization local relationships INR and narrow quantization gap between training encoding further improve Our framework consists latent corresponding...

Image compression aims to minimize the amount of data in image representation while maintaining a certain visual quality for humans, which is an essential technique storage and transmission. Recently, along with development computer vision, machines have become another primary receiver images require compressed at level, may be different from that human vision. In many scenarios, should serve both machine vision tasks, but few methods are designed goals simultaneously. this article, we...

The performance for free-pGaN deep-ultraviolet light-emitting diodes (DUV LEDs) is still limited by total internal reflection (TIR), p-electrode absorption, and self-heating effect. In this study, we propose inserting a layer of self-assembled Ni nanoparticle array between p-AlGaN (Ni/Au). experimental results demonstrate that compared to conventional DUV LEDs, the proposed device exhibits significant improvements in optical power, forward voltage, thermal characteristics. This due fact...

Video compression has always been a popular research area, where many traditional and deep video methods have proposed. These typically rely on signal prediction theory to enhance performance by designing high efficient intra inter strategies compressing frames one one. In this paper, we propose novel model-based (MVC) framework that regards scenes as the fundamental units for sequences. Our proposed MVC directly models intensity variation of entire sequence in scene, seeking non-redundant...

Low light extraction efficiency (LEE), high forward voltage and severe self-heating effect greatly affect the performance for AlGaN-based deep ultraviolet light-emitting diodes (DUV LEDs). In this work, surface-textured Ga-face n-AlGaN is fabricated low-costly using self-assembled SiO2 nanosphere as hard mask. The experimental results manifest that when compared with conventional DUV LEDs, optical power, thermal characteristics LEDs are improved obviously. It because between mesa n-electrode...

Severe burns induce a catecholamine surge, causing severe damage to the organism and raising possibility of multisystem organ failure. Few strategies are generally acceptable reduce surge injury post-burn. We have previously shown that histamine can amplify surge. In addition, promethazine, first-generation H1 receptor antagonist, alleviates after in rats. However, evidence is lacking on whether promethazine benefits patients burns. Currently, sedation analgesia (such as midazolam fentanyl)...

Tuning the plasmonic resonance peak to deep ultraviolet (DUV) band is critical for plasmonic-enhanced AlGaN-based DUV photodetector. However,the high refractive index of AlGaN layer seriously limits in band. Therefore, this work, we study how various Al nanoparticles on surface affect performance. Compared with Al-based nanosphere, nanohemisphere and nanodisk, nanorod most suitable candidate photodetectors. This because dipolar mode excited from upper part not affected by interface between...

In this work, by using three-dimensional finite-difference time-domain (3D FDTD) method, the effect of conventional nano-patterned sapphire substrate (NPSS) on optical crosstalk and light extraction efficiency (LEE) for InGaN/GaN-based flip-chip micro light-emitting diodes (µ-LEDs) are systematically studied. We find that NPSS is not suitable µ-LEDs. It because inclined mesa sidewall µ-LEDs possesses a good scattering µ-LEDs, but introduced causes part be off escape cone between air become...
