An equalization technique for orthogonal frequency-division multiplexing systems in time-variant multipath channels

IEEE Transactions on Communications, 1999
A loss of subchannel orthogonality due to time-variant multipath channels in orthogonal frequency division multiplexing (OFDM) systems leads to interchannel interference (ICI) which increases the error floor in proportion to the Doppler frequency.

The Morphological, Behavioral, and Transcriptomic Life Cycle of Anthrobots

Advanced Science, EarlyView.
DNA is thought to determine shape, behavior, and lifespan, with developmental plasticity reserved for stem cells, embryos, and species like amphibia. How much morphogenetic plasticity do adult somatic human cells exhibit? Anthrobots are a self‐organizing, motile synthetic living construct made of genetically normal human epithelial cells.

Piezo1 Activation Improves NSCLC Liver Metastasis Immunotherapy by Overriding Matrix Stiffness‐Mediated Bimodal PD‐L1/CXCL10 Regulation

Advanced Science, EarlyView.
This study demonstrates that Piezo1 activation enhances FAK‐YAP‐mediated upregulation of PD‐L1 and CXCL10, thereby promoting an immunotherapy‐responsive tumor microenvironment in NSCLC. Cyclic stretch modulates the PD‐L1/CXCL10 response to ECM stiffness, reshaping their expression dynamics.

36‐Channel Spin and Wavelength Co‐Multiplexed Metasurface Holography by Phase‐Gradient Inverse Design

Advanced Science, EarlyView.
A single‐cell metasurface is designed to multiplex holographic images across both spin and wavelength channels using a single‐phase map. By employing inverse design and automatic differentiation, the metasurface achieves 36 channel multiplexing across the visible to near‐infrared spectrum.

Controlling Peak-to-Average Power Ratio in Orthogonal Frequency Division Multiplexing System

Journal of Engineering and Sustainable Development, 2013
A major drawback of Orthogonal Frequency Division Multiplexing at the transmitter side is the high peak-to-average power ratio (PAPR) of the signal. Conventional solutions for this problem are to use a linear amplifier ( or to back-off the operating ...

Targeting Hyperglycemic Bone Pre‐Metastatic Niche for Breast Cancer Bone Metastasis Therapy

Advanced Science, EarlyView.
This study reveals that breast cancer creates a hyperglycemic pre‐metastatic niche in bone prior to colonization and amplifies glucose metabolism post‐metastasis. To target this mechanism, a biomimetic enzyme‐engineered nanoplatform that disrupts tumor glycolytic pathways, proposing a therapeutic strategy to inhibit breast cancer bone metastasis by ...
