The Guadalupian mass extinction took place during the major global environmental changes during Phanerozoic time. Large-scale sea-level fluctuations and a negative shift of δ¹³ C were associated with this crisis. However, the diagenetic or primary origin of the decreased δ¹³ C across the Guadalupian–Lopingian (G–L) boundary and the potential causes...

Atmospheric transfer correction is important to the measurement of target's radiation characteristic. Following the former paper, an atmospheric transfer correction system and the moderate-spectral-resolution combined atmospheric radiative transfer (CART) code were introduced. The comparisons of atmospheric correction and horizontal measurement res...

The signal of a target measured by electro-optics detector is attenuated by the atmosphere and affected by atmospheric background radiance. Atmospheric transfer correction is important to the measurement of target's radiation characteristic. The commonly-used atmospheric radiative transfer models and the detecting methods of important atmospheric o...

The mid-infrared atmospheric transmittance and radiation were calculated with four different HITRAN databases using LBL software. Results show that atmospheric transmittance is increases with the transmission path decreases. Radiation decreases with the transmission path decreases. The transmittance average absolute deviation of HITRAN96, HITRAN2k...

The mid-infrared atmospheric transmittance and the absolute deviation were calculated with three different HITRAN databases using LBL software. Results show that the average absolute deviation of HITRAN2k and HITRAN04 decreases with the increase of initial height, the absolute deviation of HITRAN2k and HITRAN04 increases as the resolution increases...

To validate the combined atmospheric radiative transfer model(CART) code on calculating the scattering of atmospheric molecules and aerosol particles, comparisons of CART scattering results (including the single scattering radiance and multiple scattering radiance) to the moderate resolution atmospheric transmittance and radiance code (MODTRAN5. 0)...

To validate the precision of atmospheric molecular absorption and thermal radiance calculated by combined atmospheric radiative transfer (CART) code, using the accurate line-by-line atmospheric transfer model (LBLRTM) and moderate resolution atmospheric transmission (MODTRAN4.0), the atmospheric molecular absorption spectral transmittance and infra...

The infrared atmospheric spectral radiances with high spectral resolution (1 cm -1) from sky background were measured on the ground using Fourier transform infrared radiometer (FTIR). The background spectral radiances at infrared waveband of 5 to 14 μm were obtained. The relationship between sky spectral radiances and the vertical column atmospheri...

An algorithm based on ADS-B was proposed to meet the demand of collision avoidance for the complicated traffic situation of Free Flight. The algorithm selected the potential conflict aircrafts within 40-1 OOnm radius, which took advantages of abundant information and high updating rate of ADS- B. Function simulation was carried out using MATLAB, th...

Expression of ABCG2 is normally absent or low in the pancreas, but high in human pancreatic cancer cells. The mechanism by which ABCG2 is altered in human cancers remains unknown. We investigated ABCG2 expression in four pancreatic cancer cell lines, and used three microRNA (miRNA) target prediction programmes, and information from the existing lit...

Gemcitabine is the first-line chemotherapeutic agent for advanced adenocarcinoma of the pancreas; however, chemoresistance to gemcitabine remains a major cause of failure for the clinical treatment of this disease. Polo-like kinase 1 (Plk-1) is highly expressed in pancreatic cancer cell lines and pancreatic tumour tissues, and is involved in a wide...
