Novel half-duplex relay strategy and its resource allocation

Tongxin xuebao, 2009
Conventional time-division half-duplex relay strategies based on amplify-and-forward or decode-and-forward strategy could relieve relay nodes from full-duplex requirement but lead to degraded spectrum efficiency.

A Distributed Pulse-Based Synchronization Protocol for Half-Duplex D2D Communications

IEEE Open Journal of the Communications Society, 2021
In distributed device-to-device (D2D) communications, no common reference time is available and the devices must employ distributed synchronization techniques.

SynNotch Receptors for Visualizing Immunoreceptor Force Transmission and Downstream Signaling In Vivo

Advanced Science, EarlyView.
A mechanically activated SynNotch reporter platform enables detection of force transmission through receptors as they mediate immune cell interactions. Targeting CD40 on B cells and TCR on T cells records force‐induced reporter activation across 2D coculture, 3D organoid, and implanted in mice, which also reveal force‐amplification of immune receptor ...

On Joint Sub-channel Allocation, Duplexing Mode Selection, and Power Control in Full-Duplex Co-Channel Femtocell Networks [PDF]

AUT Journal of Electrical Engineering, 2018
As one of the promising approaches to increase the network capacity, Full-duplex (FD) communications have recently gained a remarkable attention. FD communication enables wireless nodes to simultaneously send and receive data through the same frequency ...

A Cascaded DNA Nanocircuit for Multi‐Signal‐Responsive Precision siRNA Delivery in Cancer Therapy

Advanced Science, EarlyView.
A cascaded dual‐AND logic DNA nanocircuit is engineered to respond to three tumor‐specific signals in a sequential manner: extracellular acidic pH, membrane‐overexpressed nucleolin (NCL), and intracellular glutathione (GSH). This programmable system selectively releases siPARP1 in glioblastoma (GBM), effectively silencing PARP1 and reversing TMZ ...

Special Section on Full-Duplex Transceivers for Future Networks: Theory and Techniques

IEEE Open Journal of the Communications Society, 2021
Conventional wireless communication systems operate in a half-duplex mode, i.e., current radios cannot transmit and receive at the same time and on the same frequency. Full-duplex wireless operation was generally assumed to be impossible due to the great

Iliofemoral Deep Vein Thrombosis Despite Repeatedly Negative D-Dimer Results. [PDF]

Clin Case Rep
ABSTRACT A 75‐year‐old man presented with a three‐week history of left lower‐limb pain and repeatedly negative D‐dimer results. Doppler ultrasonography ultimately revealed extensive iliofemoral deep vein thrombosis (DVT). This case highlights that a negative D‐dimer result does not exclude subacute DVT and that clinical suspicion should prevail over ...

DyProL: Dynamic Ensemble Representation Learning for Protein–Nucleic Acid Binding Site Prediction

Advanced Science, EarlyView.
Protein function is represented as a dynamic conformational ensemble rather than a single static structure. A multi‐conformation geometric attention framework aligns, clusters, and learns representative states to capture residue‐ and ensemble‐level signals. Integrating structural dynamics improves interpretable protein‐NA binding prediction and reveals
