Abstract The detection of primordial B-modes, a key probe of cosmic inflation, is increasingly challenged by contamination from weak gravitational lensing B-modes induced by large-scale structure (LSS). We present a delensing pipeline designed to enhance the sensitivity to the inflationary parameter...

To address the limitations of conventional strategies for differentiation human induced pluripotent stem cells (hiPSCs) into homogeneous hepatocytes, a doxycycline-inducible GATA6-expressing hiPSC line was developed using the PiggyBac transposon system. This hiPSC line permitted temporal control of...
