Physical Layer Security Performance Analysis of the FD-Based NOMA-VC System

IEEE Access, 2019
In this paper, we consider the secrecy outage probability (SOP) of a cooperative non-orthogonal multiple access (NOMA) vehicular communication (VC) system, where the relay is working in either half-duplex (HD) or full-duplex (FD) mode. We assume that all

Interference Management with Partial Uplink/Downlink Spectrum Overlap

, 2015
Simultaneous reuse of spectral resources by uplink and downlink, denoted as in-band full duplex (FD) communication, is promoted to double the spectral efficiency when compared to its half-duplex (HD) counterpart. Interference management, however, remains

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

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 ...

The Capacity of the Gaussian Cooperative Two-user Multiple Access Channel to within a Constant Gap

, 2012
The capacity region of the cooperative two-user Multiple Access Channel (MAC) in Gaussian noise is determined to within a constant gap for both the Full-Duplex (FD) and Half-Duplex (HD) case. The main contributions are: (a) for both FD and HD: unilateral

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 ...

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 ...

Multi-Objective Optimization for Power Efficient Full-Duplex Wireless Communication Systems

, 2015
In this paper, we investigate power efficient resource allocation algorithm design for multiuser wireless communication systems employing a full-duplex (FD) radio base station for serving multiple half-duplex (HD) downlink and uplink users simultaneously.

The Structural Refinement of Commercial‐Purity Copper Processed by Equal Channel Angular Pressing with Low Strain Amplitude

Advanced Engineering Materials, Volume 27, Issue 21, November 2025.
Equal channel angular pressing of commercial pure copper under low strain amplitude (≈0.48) induces concurrent continuous and localized discontinuous dynamic recrystallization, forming a duplex structure influenced by strain heterogeneity and recovery. Moderate hardening after 4–12 passes results from progressive high‐angle grain boundary formation via
