High temperature is one of the major impediments limiting the growth and development of most edible fungi. While many efforts have been made in agricultural practice, the mechanism for resistance to high temperature remains elusive. Nitric oxide (NO) is considered as a signaling molecule involved in regulation of diverse physiological processes and stress(More)
of time-dependent PDEs that arise in wave phenomena. The schemes are constructed via the prolate spheroidal wave functions (PSWFs). Compared to existing differentiation schemes based on orthogonal polynomials, the new class of differentiation schemes requires fewer points per wavelength to achieve the same accuracy when it is used to approximate derivatives(More)
Following the recent work Schaeffer and Osher (SIAM J Imaging Sci 6:226–262, 2013), the low patch-rank interpretation for the oscillating patterns of an image validates the application of matrix-rank optimization to image decomposition. Therein, the problem was mathematically modeled as a separable convex programming with three-block (a total variation(More)
PDK1 is a member of the atypical glandular cell kinases family that regulates the activities of most atypical glandular cell kinases during different development stages and treatment of cancers. PDK1 is also a critical glucose metabolism enzyme regulating glucolysis or glucose oxidase in cells, and more research is needed to further understand the(More)
In this study, we focus on the problem of landing an unmanned aerial vehicle (UAV) in unknown and Global Navigation Satellite System(GNSS)-denied environments based on an infrared stereo vision system. This system is fixed on the ground and used to track the UAV's position during the landing process. In order to enlarge the search field of view (FOV), a(More)
This paper presents a new ground-based visual approach for guidance and safe landing of an unmanned aerial vehicle (UAV) in Global Navigation Satellite System(GNSS)-denied environments. In our previous work, the old system consists of one pan-tilt unit(PTU) with two cameras, whose detection range is limited by the baseline. To achieve long-range detection(More)
Recently, there has been growing interest in developing unmanned aircraft system (UAS) based on visual sensors. During the whole autonomous assignment, the landing procedure is one of the most dangerous and challenging process. For most of unmanned aircraft vehicle, visual sensors are the basic equipment, which are also widely used during the landing(More)
Genetic modification of barley variety can be an efficient way to improve beer quality. The objective of this study was to understand the effect of trxS gene on hydrolases activities in transgenic and non-transgenic barley seeds. The results showed that alpha-amylase, free beta-amylase and limit dextrinase activity were increased in transgenic seeds in(More)
This article mainly focuses on the vision-based obstacle avoidance of unmanned aerial vehicle (UAV). Detecting the obstacle and controlling the UAV to avoid it are two key modules in the sense-and-avoid system. We adopt a bio-inspired human vision algorithm called saliency method to realize the automatic detection. Furthermore, this article proposes a(More)
The scan registration is the cornerstone to Mobile Robotic Mapping, and the majority of existing global registration methods are dependent on specific features. This paper presents a global feature-less scan registration strategy based on the ground surface, which is extremely common in Mobile Robotic Mapping scenarios. The 3D rotation is decoupled from 3D(More)
