Near-Capacity Turbo Coded Soft-decision Aided DAPSK/Star-QAM for Amplify-and-Forward based Cooperative Communications [PDF]
Multilevel Differential Amplitude and Phase-Shift Keying (DAPSK) schemes do not require any channel estimation, which results in low complexity.

During kidney aging, loss of the MICOS complex drives cristae disorganization, impairs oxidative capacity, and alters mitochondrial dynamics. MICOS disruption elevates mitochondrial ROS and disrupts calcium homeostasis, linking mitochondrial structural remodeling to metabolic dysfunction in aging kidney tissue.

Resonant Tunneling Diode‐Integrated Terahertz Transceiver Module for Wireless Communications
Resonant tunneling diode‐enabled terahertz transceiver module. Terahertz bands are essential for next‐generation wireless communications, offering ultrabroad bandwidth and unprecedented data throughput. However, realizing compact, low‐cost, broadband, and efficient terahertz transceiver modules remains challenging.

Low-Complexity Detection of High-Order QAM Faster-Than-Nyquist Signaling
Faster-than-Nyquist (FTN) signaling is a promising non-orthogonal transmission technique to considerably improve the spectral efficiency. This paper presents the first attempt in the literature to estimate the transmit data symbols of any high-order ...

Spatial multi‐omics defines a DLL4–NOTCH3–driven capillary–mCAF axis orchestrating fibrotic remodeling and immune exclusion in hepatocellular carcinoma tumor cores, conferring immune checkpoint blockade resistance. Targeting stromal NOTCH3 disrupts this pro‐fibrotic niche, enhances T cell infiltration, and synergizes with anti‐PD‐1 therapy ...

Analysis of Frequency Conversion for M-QAM and M-PSK Modems [PDF]
this paper is greatly simplified compared to the method adopted in this thesis. Standard error rate expressions for M--QAM and M--PSK as given in Proakis [8] are used.
