Multicarrier Division Duplex Aided Millimeter Wave Communications

IEEE Access, 2019
The existing time-division duplex (TDD) and frequency-division duplex (FDD) techniques rely on a guard time and/or a guard band to avoid self-interference (SI) between the uplink and downlink channels, which results in the wastage of precious spectral ...

Enhancing G‐Quadruplex Binding: Rational Design and Biophysical Evaluation of Dimeric Ligands

Chemistry – A European Journal, Volume 31, Issue 72, December 23, 2025.
Fluorescence thermal shift assays, electrospray ionization‐mass spectrometry, CD spectroscopy, molecular modeling and cytotoxicity assays were enrolled to study the binding of a rationally designed anthraquinone‐based G‐quadruplex binder interacting with the nucleic acid as a molecular tweezer.

Multi-User Cooperative Non-Orthogonal Multiple Access Scheme With Hybrid Full/Half-Duplex User-Assisted Relaying

IEEE Access, 2019
This paper has investigated a downlink non-orthogonal multiple access (NOMA) cooperative scheme with user-assisted relaying, where near users are viewed as decode-and-forward (DF) relays operating full/half-duplex mode to assist multiple far users ...

Full-Duplex Radio for Uplink/Downlink Transmission with Spatial Randomness

, 2015
We consider a wireless system with a full-duplex (FD) access point (AP) that transmits to a scheduled user in the downlink (DL) channel, while receiving data from an user in the uplink (UL) channel at the same time on the same frequency.

Post‐fire Behaviour of Stainless Steel Rebars

ce/papers, Volume 8, Issue 6, Page 745-750, December 2025.
Abstract Stainless steel rebars (SSR) offer significant advantages for reinforced concrete structures, especially in environments where corrosion is a major concern. Also, SSR exhibit excellent mechanical strength, high ductility, and reliable performance at elevated temperatures.

Unveiling the influence of gravity on pitting corrosion through advanced high‐throughput corrosion test method

Materials Genome Engineering Advances, Volume 3, Issue 4, December 2025.
Bipolar electrochemistry enables high‐throughput investigation of gravity's effect on pitting corrosion in stainless steel (type 304L/420). By varying specimen orientation, significant gravity‐induced changes in pit nucleation, propagation, and morphology are observed on the bipolar electrodes across a wide range of applied potentials. Abstract Bipolar

Forearc Depressions Develop in Warm Subduction Zones by Underplating‐Induced Crustal Flexure

Terra Nova, Volume 37, Issue 6, Page 431-438, December 2025.
ABSTRACT We propose a model for forearc depression formation in warm subduction zones. Forearc depressions overlie some ocean‐continent subduction zones and form between a forearc high and volcanic arc. Forearc highs coincide with 51–91 mGal free‐air gravity anomalies and km‐scale reflector bands in seismic sections, indicating they comprise crust ...
