Effect of Unpredictable Interference on MU-MIMO Systems in HetNet

IEEE Access, 2018
In this paper, we investigate the outage probability of a multiuser multiple-input multipleoutput (MU-MIMO) system in the heterogeneous network (HetNet) in the presence of unpredictable interference (UI) from coexisting ad hoc systems.

Upcycling of Photovoltaic Silicon Waste via Molten Salt Electrolysis for the Synthesis of High‐Performance Silicon Nanowire Anodes

Carbon Neutralization, Volume 5, Issue 2, March 2026.
This study developed a stepwise electrolysis process that converts photovoltaic silicon waste into high‐value silicon anode materials, transforming sheet‐like silicon waste into silicon nanowires. The method enhances resource utilization efficiency and offers a promising approach for developing high‐performance Li‐ion battery anodes.

Adaptable waveform design for radar and jammer for multi-target using game theoretic strategies

EURASIP Journal on Advances in Signal Processing, 2022
In the environment of electronic warfare, the countermeasure between radar and jammer has become a hot issue. Finding the solution to optimal waveforms between them is very great significance.

Multi-Broadcasting under the SINR Model

CoRR, 2015
We study the multi-broadcast problem in multi-hop wireless networks under the SINR model deployed in the 2D Euclidean plane. In multi-broadcast, there are $k$ initial rumours, potentially belonging to different nodes, that must be forwarded to all $n$ nodes of the network.

Dynamic Resource Allocation for LEO Satellite Systems Under Heterogeneous Traffic Distributions

International Journal of Satellite Communications and Networking, Volume 44, Issue 2, Page 199-209, March/April 2026.
ABSTRACT This paper proposes an efficient resource allocation scheme for low Earth orbit (LEO) satellite systems. Taking into account the unique characteristics of LEO systems for 6G communication services, we introduce a dynamic bandwidth and power allocation scheme specifically designed to accommodate highly heterogeneous traffic distributions.

Contribution of non‐orthogonal multiple access signalling to practical multibeam satellite deployments

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 73-88, January/February 2026.
The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.

Second messenger signaling in Bacillus subtilis: accumulation of cyclic di-AMP inhibits biofilm formation

Frontiers in Microbiology, 2016
The Gram-positive model organism Bacillus subtilis produces the essential second messenger signaling nucleotide cyclic di-AMP. In B. subtilis and other bacteria, c-di-AMP has been implicated in diverse functions such as control of metabolism, cell ...

Evaluation of multi‐user multiple‐input multiple‐output digital beamforming algorithms in B5G/6G low Earth orbit satellite systems

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 17-33, January/February 2026.
In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

5G new radio multiuser precoding in geostationary satellite networks

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 60-72, January/February 2026.
This work evaluates the standardized 5G new radio codebooks for closed‐loop multiuser precoding in GEO multibeam scenarios and derives a list of recommended 3GPP standard modifications for a proper support to GEO mission needs. Summary The multiuser precoding procedures standardized by the 3rd Generation Partnership Project (3GPP) for new radio (NR ...

The FsrA‐Mediated Iron‐Sparing Response Regulates the Biosynthesis of the Epipeptide EPE in Bacillus subtilis

Molecular Microbiology, Volume 125, Issue 2, Page 108-122, February 2026.
Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.
