The development and provision of soil spectral library (SSL) could facilitate the application near infrared (NIR) spectroscopy for economical, accurate, efficient determination organic matter (SOM). In this work, performances partial least squares regression (PLSR) convolutional neural network (CNN) combined with datasets Zhejiang provincial SSL (ZSSL) feature subset (FS) were compared predic...

High-performance liquid chromatography (HPLC) fingerprinting is a reliable quality control method for traditional Chinese medicine (TCM). As research combining fingerprint and pharmacodynamics of TCM, the TCM spectral effect relationship widely used in its preparations, which can better reflect intrinsic great significance on material basis efficacy. In this study, an HPLC extracts from aerial ...

Snow pears are an important and widespread agricultural product that can relieve respiratory symptoms, constipation, alcoholism. Lignin content (LC) has a direct negative role on the fruit texture taste of snow pears. Here, we studied effect near-infrared (NIR) spectroscopy determination LC in due to position at which spectral measurements were obtained. NIR diffuse reflection spectra collected...

Soil organic matter (SOM) is one of the most important indicators soil quality. Hyperspectral remote sensing technology has been recognized as an effective method to rapidly estimate SOM content. In this study, 173 samples (0–20 cm) were collected from farmland soils in northwestern arid zones China. Partial least squares regression (PLSR), support vector machine (SVMR), and random forests (RFR...

Major histocompatibility complex (MHC) class I molecules present thousands of peptides to allow CD8+ T cells to detect abnormal intracellular proteins. The antigen-processing pathway for generating peptides begins in the cytoplasm, and the MHC molecules are loaded in the endoplasmic reticulum. However, the nature of peptide pool in the endoplasmic reticulum and the proteolytic events that occur...

In an era in which schools are expected to achieve more for their students, many teachers remain frustrated by the increasing results-driven demands made on them. A facet of teacher work life in which many feel disempowered is addressed in this study—the regular infringement of outside intrusions into the classroom learning environment. A stratified random selection of teachers in the Canadian ...

As consumers’ preference for sweetness in food products is increasing, most agricultural product processing complexes currently operate sugar-screening machines. However, every season, the entire prediction models have to be modified fit fruit species cultivated that season using a long-drawn process, because separate are required each species. Therefore, this study, species-integrated were exa...

Assessment and monitoring of soil organic matter (SOM) quality are important for understanding SOM dynamics and developing management practices that will enhance and maintain the productivity of agricultural soils. Visible and near-infrared (Vis-NIR) diffuse reflectance spectroscopy (350-2500 nm) has received increasing attention over the recent decades as a promising technique for SOM analysis...

Introduction The term teratoma, derived from the Greek teraton meaning “a monster”, was coined by Virchow in 1869 for a tumour originating in the sacrococcygeal region. Teratomas are composed of multiple tissues foreign to the organ or site in which they arise. Although teratomas are sometimes defined as having the three embryonic layers (endoderm, mesoderm, and ectoderm), recent classification...

The use of dental implants to assist in the treatment of partial and complete edentulism is well documented. Most of the implant literature, however, reports results associated with implant survival and success when there has been adherence to rigid placement and loading protocols. Conventionally, these protocols call for the undisturbed healing of the implant—3 months in the mandible and 4 to ...
