In the field of remote sensing image processing, the classification of hyperspectral image (HSI) is a hot topic. There are two main problems lead to the classification accuracy unsatisfactory. One problem is that the recent research on HSI classifica

Background Hepatocellular carcinoma (HCC) is a common tumor malignancy threatening a significant number of people worldwide. Although microRNAs (miRNAs) have been shown to play essential role in tumorigenesis, little is known about their role in T ce

Two optical methods, namely crystal facet reflection and etching pits reflection, were used to orient and high-purity germanium crystals. The X-ray diffraction patterns of three slices that were cut from the oriented and crystals were measured by X-r

The ^2F_(7/2) ↔ ^2F_(5/2) optical transitions of Yb^(3+) doped into Y_3Al_5O_(12) (YAG) were studied for potential quantum information and photonic signal processing applications. Absorption and fluorescence spectroscopy located the energy levels o

Background and Aims Increasing evidence suggests that elevated serum levels of C-reactive protein (CRP) are associated with poor survival in many malignant tumors. However, the prognostic value of CRP in advanced gastric cancer (AGC) remains uncertai

Growing large diameter (∼15 cm) dislocation-free crystals for the GEODM experiment at DUSEL is a challenging task. A crystal of such high purity and large size has never been grown before and the process will require much research and development.

Noble liquid-based dark matter detectors are sensitive to parts-per-billion (ppb) concentrations of impurities of O2, N2, and H2O, which reduce the scintillation light yield and disrupt the ionization signal. In order to achieve an optimal light yiel
