A novel relay scheme for the asymmetry multiple access relay channel
, 2012 In this paper, we study the transmission mechanism for the asymmetry multiple access relay channel (AMARC), where the channel qualities from the sources to the relay are different.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research
FEBS Letters, EarlyView.What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Optimized RSMA and NOMA Transmission in MIMO Downlinks With Quantized Channel Direction Information
IEEE Open Journal of the Communications SocietyChannel state information is essential for optimizing transmit precoding in multiple-input multiple-output (MIMO) downlinks. This work assumes that only quantized channel direction information (CDI), representing the normalized channel vector, is ...

Sum Capacity for Single-Cell Multi-User Systems with M-Ary Inputs
Entropy, 2017 This paper investigates the sum capacity of a single-cell multi-user system under the constraint that the transmitted signal is adopted from M-ary two-dimensional constellation with equal probability for both uplink, i.e., multiple access channel (MAC ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer
Molecular Oncology, EarlyView.Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Classical -Quantum Multiple Access Channel with Secrecy Constraint: One-shot Rate Region
International Journal of Information and Communication Technology Research, 2020 In this paper, we aim to study a -user quantum multiple access wiretap channel with an arbitrary number of wiretappers under one-shot setting. In this regard, we first introduce the general quantum multiple access wiretap channel and the simplified ...

Frequency-domain transmit processing for MIMO SC-FDMA in wideband propagation channels [PDF]
, 2009 Recently there has been considerable interest in the use of single carrier frequency division multiple access (SC-FDMA) as the uplink transmission scheme for the 3GPP long term evolution (LTE) standard.

Molecular Oncology, EarlyView.We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Performance improvement of non-orthogonal multiple access scheme using code division multiplexing
International Journal of Distributed Sensor Networks, 2017 Currently, the standardization of fifth-generation mobile communication system (5G), which realizes 10 Gbps transmission, is in progress. In mobile communications, it is generally difficult to perform high-capacity transmission because of channel fading.
