We describe an extremely rare case of a 66-year-old woman with a vaginal epithelioid angiosarcoma.She presented with constitutional symptoms, pelvic pain, vaginal bleeding, and a violaceous vaginal lesion.A thorough gynaecological examination, tissue biopsy and imaging were crucial to establish an accurate diagnosis.With only 3 other cases reported

Harnessing the full power of nascent quantum processors requires the efficient management of a limited number of quantum bits with finite coherent lifetimes.Hybrid algorithms, such as the variational quantum eigensolver (VQE), leverage classical resources to reduce the required number of quantum gates.Experimental demonstrations of VQE have resulte

We use ground-based observations of CO mixing ratios and vertical column abundances together with tropospheric NO2 columns from the GOME satellite instrument as constraints for improving the global annual emission estimates of CO and NOx for the year 1997.The agreement between concentrations calculated by the global 3-dimensional CTM IMAGES and the

This study extends the work of Liew et al.(2003) in two directions.First, it examines whether or not the 1997 Asian currency crisis has resulted in the nonlinearity of ASEAN-5 real exchange rates.Second, it characterizes the type of nonlinearity governing these rates.Results of the current study, among others, show that nonlinearity existed even be
