5G new radio design:why/how to extend/innovate from LTE
Dianxin kexue, 2019 Driven by the 5G visions including “wireless infrastructure to connect the world”, ITU has defined the three main usage scenarios of 5G: eMBB, mMTC, and uRLLC, and the consequent requirements (performance metrics) are defined as well.

Signal design and analysis for cell identification in Sub-THz OFDM systems
ICT ExpressHere we propose a new signal set design for physical cell identification (PCI) in sub-THz OFDM systems. We also derive useful properties of proposed signal set, which can be employed to assign PCI and reduce interference.

Advanced Materials, EarlyView.The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Advanced Science, EarlyView.An intracellular magneto‐mechanical platform utilizing MSC‐targeted nanomotors is developed. After intra‐articular delivery, these nanomotors target endogenous BMSCs and are actuated within lysosomes to execute trans‐planar rotational‐bouncing motions under a rotating‐fluctuating 3D magnetic field, generating amplified mechanical stimulation.
