Acoustic Signals Improve Correlation-based Leak Detection Techniques Performance[Jul 19, 2017]

Researcher GAO Yan from the Institute of Acoustics of the Chinese Academy of Sciences together with some researchers from China, Brazil and the UK have been investigating time delay estimation using the cross-correlation of leak noise signals in buried plastic water pipes. They present a procedure in which the shape of the cross-correlation function can be significantly improved, resulting in an unambiguous and clear estimate of the time delay.

ASXL2 Plays a Critical Role in Normal and Malignant Hematopoiesis[Jul 18, 2017]

Hematopoietic stem cells (HSCs) are the stem cells that give rise to all lineages of blood cells. A new study conducted by Dr. WANG Qianfei from Beijing Institute of Genomics of Chinese Academy of Sciences, and Drs. YANG Fengchun and XU Mingjiang from University of Miami Miller School of Medicine, reported that loss of Asxl2 alters self-renewal and cell fate of HSCs, leading to myelodysplastic syndrome-like disease in mice.
