Comparative Genome Analysis of Three Halobacillus Strains Isolated From Saline Environments Reveal Potential Salt Tolerance and Algicidal Mechanisms

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Following the previous complete genome analysis, this research provides the function of new Halobacillus species. Three strains were identified: Halobacillus shinanisalinarum sp. nov. SSTM10‐2T, Halobacillus salinarum sp. nov. SSBR10‐3T, and Halobacillus amylolyticus sp. nov. SSHM10‐5T.

Tractable Resource Management with Uplink Decoupled Millimeter-Wave Overlay in Ultra-Dense Cellular Networks

, 2016
The forthcoming 5G cellular network is expected to overlay millimeter-wave (mmW) transmissions with the incumbent micro-wave ({\mu}W) architecture. The overall mm-{\mu}W resource management should therefore harmonize with each other.

Compressive sensing based PAPR reduction in OFDM systems: Modified orthogonal matching pursuit approach

ICT Express, 2020
Orthogonal frequency division multiplexing (OFDM) has been proposed to achieve high data rate transmission in wireless communications. The OFDM system usually suffers from the high envelope fluctuations called peak-to-average power ratio (PAPR). The high

Efficient Parallel PAPR Reduction Method Using Null-Constrained Peak Cancellation Signal for Massive MIMO-OFDM Systems

IEEE Open Journal of the Communications Society
In this paper, we propose new methods for reducing the peak-to-average power ratio (PAPR) for downlink massive multiple-input multiple-output (MIMO) along with orthogonal frequency division multiplexing. We develop the PAPR reduction method based on peak

Verifying Proper Function of the Aerosol Evacuation System Prior to Sorting Potentially Infectious Samples

Current Protocols, Volume 5, Issue 3, March 2025.
Abstract High concentrations of aerosols can be generated within the sort collection area of cell sorters during instrument failures that cause the stream to deviate, such as a partial nozzle obstruction. Complete containment of these aerosol particles becomes essential for operator safety when working with potentially infectious or hazardous samples ...
