To evaluate environment hazards of tetracyclines (TCs) on different soils from the north China, desorption hysteresis index and partition coefficients (Kd) were obtained by sorption–desorption experiments. Five soils, including black soil (BLA), cinnamon (CIN), cultivated loessial (CUL), castanozems, brown (BRO), collected to test properties oxytetracycline (OTC). Molecular TC, chlortetracycline (CTC), OTC acquired quantum chemistry calculations explain differences CUL. Among five BLA...

Robust feature tracking is a requirement for many computer vision tasks such as indoor robot navigation. However, scenes are characterized by poorly localizable features. As result, without artificial markers challenging and remains an attractive problem. We propose to solve this problem constraining the locations of large number nondistinctive features several planar homographies which strategically computed using distinctive experimentally show need multiple illumination-invariant...

Abstract The fruits of Forsythia suspensa ( F. ) have been used as a traditional Chinese medicine for 2000 years. Currently, the quality control strictly follows instructions Pharmacopeia, which mainly controls content forsythoside A, phillyrin, and volatile oil. In this study, air pressure MALDI mass spectrometry imaging (AP‐MALDI MSI) was to evaluate distribution dozens active ingredients. variation ingredients measured more than 30 batches samples, regarding harvest time, cultivated...

Video content analysis is essential for efficient and intelligent utilizations of vast multimedia databases over the Internet. In video sequences, object-based extraction techniques are important content-based processing in many applications. this paper, a novel technique developed to extract objects from sequences based on spatiotemporal independent component (stICA) multiscale analysis. The stICA used preliminary source images containing moving sequences. image data obtained after further...

Frozen section examination could provide pathological diagnosis for surgery of thyroid nodules, which is time-consuming, skill- and experience-dependent. This study developed a rapid classification method nodules machine learning. Total 69 tissues were collected including 43 26 nodule-adjacent tissues. Intraoperative frozen was first performed to give accurate diagnosis, the rest specimen pretreated probe electrospray ionization mass measurement. By multivariate analysis scan data, series...

Monocular vision based robot navigation requires feature tracking for localization. In this paper we present a system using discriminative features as well less features. Discriminative such SIFT are easily tracked and useful to obtain the initial estimates of transforms affinities homographies. On other hand Harris corners manually selected not in subsequent frame due problems matching. We use planar homographies representing motion major structures scene. Planar structure assumption is...

In this paper, two new methods are proposed for robotic simultaneous localization and map building (SLAM), namely high level geometric knowledge constraint newly acquired feature initialization. These implemented within classic extended Kalman filter (EKF) framework. Novelties lie in aspects. First, information, such as common primitives (e.g. lines triangles) constructed by observed points, is incorporated to EKF enhance the robustness resistance noise. Second, a visual measurement...
