In this paper, based on the block Markov superposition transmission (BMST) technique, we present a new class of coupled low-density parity-check (LDPC) codes for the transport block (TB)-based transmission to improve the error-correcting performance. For encoding, the previous LDPC codewords corresp...

In this paper, we propose a new class of nonbinary polar codes, where the symbol-level polarization is achieved by using a 2 × 2 q-ary matrix 10β1 as the kernel. Under bit-level code construction, some partially-frozen symbols exist, where the frozen bits in these symbols can be used as active-check...

Abstract Violent waves in ocean sometimes cause huge shocks to the oscillating buoy and cause its damage. Improving the structure of buoy is a common method to reduce the impact of water on buoy. This paper focuses on how to reduce the peak impact force and improve the survivability of oscillating b...

BackgroundAlthough physical activity (PA) levels among female students have improved in primary and secondary education, female undergraduates consistently show lower PA levels compared to males and younger female students. Previous studies suggest that gender stereotypes and socially constructed tr...

Mangrove coastal wetland soils store a large amount of organic matter (OM), playing a significant role in the global carbon and nitrogen cycle. However, the sources and distribution of soil OM in mangrove wetlands remain unclear. Stable isotope and fluorescence spectrometry were used to study the so...

Abstract Graphene have been considered as the one of the most promising anode materials for the next generation lithium‐ion batteries (LIBs) due to its unique properties compared to that of the commercial available graphite anode. However, the tedious preparation process, high cost and easy aggregat...

ABSTRACT Screening for colonization is an essential procedure in allogeneic hematopoietic stem cell transplantation (allo-HSCT). Although metagenomic next-generation sequencing (mNGS) has played an important role in the diagnosis of complex and challenging infections, its effectiveness in screening...

Research on young trees’ adaptation to shade has predominantly focused on leaf-level responses, overlooking critical structural and functional adaptations in branch systems. In this study, we address this gap by investigating hierarchical branch morphology–physiology integration in 20-year-old <i...

The Symbiotic star (SySt) is a long-period interacting binary system, typically consisting of a white dwarf (WD) and a red giant surrounded by a nebula. These systems are natural astrophysical laboratories for investigating binary star evolution. In this paper, we identified nine SySts from the Larg...

ABSTRACT Disentangling the phylogenetic relationship of polyploid species is essential for understanding how such polyploid species evolved following their origin. To investigate the speciation and evolutionary history of Eremopyrum, we analyzed 36 transcriptomes from 9 polyploid accessions of Eremo...

In this research, we conducted systematic photometric, spectroscopic, and theoretical modeling analyses of two δ Scuti stars—KIC 12602250 and KIC 5768203—that pulsate only in radial modes. We collected their relevant photometric and spectroscopic parameters from multiple catalogs and estimated the a...
