Abdominal compartment syndrome in a monochorionic-triamniotic triplet pregnancy complicated by feto-fetal transfusion syndrome.

A 40-year-old primigravida woman with a monochorionic-triamniotic (MT) triplet pregnancy was hospitalized due to threatened abortion at 16 gestational weeks. Polyhydramnios in two fetuses and oligohydramnios in the third supported a diagnosis of feto-fetal transfusion syndrome (FFTS) at 23 weeks and 3 days of gestation. Severe dyspnea and liver dysfunction required intensive care unit admission and mechanical ventilation support, and abdominal compartment syndrome (ACS) caused by polyhydramnios was clinically diagnosed.

Cross-Calibration between ASTER and MODIS Visible to Near-Infrared Bands for Improvement of ASTER Radiometric Calibration.

Radiometric cross-calibration between the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and the Terra-Moderate Resolution Imaging Spectroradiometer (MODIS) has been partially used to derive the ASTER radiometric calibration coefficient (RCC) curve as a function of date on visible to near-infrared bands. However, cross-calibration is not sufficiently accurate, since the effects of the differences in the sensor's spectral and spatial responses are not fully mitigated. The present study attempts to evaluate radiometric consistency across two sensors using an improved cross-calibration algorithm to address the spectral and spatial effects and derive cross-calibration-based RCCs, which increases the ASTER calibration accuracy.

Improved Accuracy of the Asymmetric Second-Order Vegetation Isoline Equation over the RED-NIR Reflectance Space.

The relationship between two reflectances of different bands is often encountered in cross calibration and parameter retrievals from remotely-sensed data. The asymmetric-order vegetation isoline is one such relationship, derived previously, where truncation error was reduced from the first-order approximated isoline by including a second-order term. This study introduces a technique for optimizing the magnitude of the second-order term and further improving the isoline equation's accuracy while maintaining the simplicity of the derived formulation.
