Preparation and catalytic performance of La0.8Sr0.2CoO3 supported on the mullite fiber ceramic

ZENG Lingke, LIU Yanchun, LIU Ping′an, WANG Hui, SHUI Anze, DUAN Bilin

Frontiers of Chemical Science and Engineering 2007, Volume 1, Issue 4,   Pages 372-376 doi: 10.1007/s11705-007-0067-8

Abstract: The perovskite-type LaSrCoO supported on the mullite fiber porous ceramics was prepared by means of the impregnating method, and was then characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD); thus we can come to the conclusion that the perovskite-type composite oxidant can disperse on the surface of mullite fiber ceramics. The catalytic activity of the LaSrCoO for NO and CO was evaluated. The effect of the doped 0.1 wt-% PdCl on the catalytic activity of the perovskite-type LaSrCoO was also discussed. The results show that the conversion rates of NO and CO respectively reaches 74.5% and 99% at 601°C without doped Pd, and both reach 100% at 350°C with a little doped Pd.

Performance analysis of visualmarkers for indoor navigation systems Article

LA DELFA,Salvatore MONTELEONE,Vincenzo CATANIA,Juan F. DE PAZ,Javier BAJO

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 8,   Pages 730-740 doi: 10.1631/FITEE.1500324

Abstract: The massive diffusion of smartphones, the growing interest in wearable devices and the Internet of Things, and the exponential rise of location based services (LBSs) have made the problem of localization and navigation inside buildings one of the most important technological challenges of recent years. Indoor positioning systems have a huge market in the retail sector and contextual advertising; in addition, they can be fundamental to increasing the quality of life for citizens if deployed inside public buildings such as hospitals, airports, and museums. Sometimes, in emergency situations, they can make the difference between life and death. Various approaches have been proposed in the literature. Recently, thanks to the high performance of smartphones’ cameras, marker-less and marker-based computer vision approaches have been investigated. In a previous paper, we proposed a technique for indoor localization and navigation using both Bluetooth low energy (BLE) and a 2D visual marker system deployed into the floor. In this paper, we presented a qualitative performance evaluation of three 2D visual markers, Vuforia, ArUco marker, and AprilTag, which are suitable for real-time applications. Our analysis focused on specific case study of visual markers placed onto the tiles, to improve the efficiency of our indoor localization and navigation approach by choosing the best visual marker system.

Engineering 2019, Volume 5, Issue 1,   Pages 115-121 doi: 10.1016/j.eng.2019.01.001

Abstract:

Forkhead box P3 (FOXP3) is a "master regulator" of regulatory T cells (Tregs), which areAs a consequence, the PTMs change the stability of FOXP3 and its capability to regulate gene expressionAlthough FOXP3 per se is not an ideal drug target, deacetylases, acetyltransferases, kinases, and other enzymes that regulate the PTMs of FOXP3 are potential targets to modulate FOXP3 and TregFOXP3" side effects must be considered when inhibitors to these enzymes are used.
