Teleosts are unique among vertebrates, with a wide range of haploid genome sizes in very close lineages, varying from less than 400 mega base pairs (Mb) for pufferfish to over 3000 Mb salmon. The cause the difference size remains largely unexplained. In this study, we reveal that differential success transposable elements (TEs) correlates variation across four representative teleost species (zebrafish, medaka, stickleback, and tetraodon). larger genomes represent higher diversity within each...

Abstracts Background Tc1/mariner and Zator , as two superfamilies of IS630-Tc1 - mariner ( ITm ) group, have been well-defined. However, the molecular evolution domestication pogo transposons, once designated an important family superfamily, are still poorly understood. Results Here, phylogenetic analysis show that transposases, together with DD34E/ Gambol transposases form four distinct monophyletic clades high bootstrap supports (> = 74%), suggesting they separate group. The superfamily...

Retrotransposons are the major determinants of genome sizes and they have shaped both genes genomes in mammalian organisms, but their overall activity, diversity, evolution dynamics, particularly impact on protein coding lncRNA pigs remain largely unknown. In present study, we performed de novo detection retrotransposons by using multiple pipelines, four distinct families pig-specific L1 s classified into 51 subfamilies representing models three expansion waves SINEs represented were...

The discovery of new members the Tc1/mariner superfamily transposons is expected based on increasing availability genome sequencing data. Here, we identified a DD35E family termed Traveler (TR). Phylogenetic analyses its DDE domain and full-length transposase showed that, although TR formed monophyletic clade, it exhibited highest sequence identity closest phylogenetic relationship with DD34E/Tc1. This displayed very restricted taxonomic distribution in animal kingdom was only detected...

Although the DD41D (named as Visitor, VS) family of Tc1/mariner transposons was discovered in Arthropods and Mollusca, evolution profile this is still largely unknown. We found that VS widespread animal kingdom, including 140 species 18 orders invertebrates 30 12 vertebrates, one land plant species. Our data revealed multiple horizontal transfer events both vertebrates invasion into lineages mammals, Chiroptera (seven species), Dasyuromorphia/Marsupialia (one Didelphimorphia/Marsupialia...

The similarities and differences of small RNAs in seminal plasma, epididymal sperm ejaculated remain largely undefined. We conducted a systematic comparative analysis RNA profiles pig sperm, plasma found that the diversity distribution species was generally similar, whereas abundance is dramatically different across three libraries; miRNAs derived from rRNA, tRNA, nuclear RNA, 7SK NRON cis-regulatory were enriched libraries, but piRNA absent. A large population are specific, only 8-30%...

Abstract Background The Tc1/mariner superfamily might represent the most diverse and widely distributed group of DNA transposons. Several families have been identified; however, exploring diversity this updating its classification is still ongoing in life sciences. Results Here we identified a new family transposons, named Incomer ( IC ), which close to, but distinct from known DD34E /Tc1 . ICs total length about 1.2 kb, harbor single open reading frame encoding ~ 346 amino acid transposase...

Abstract Global navigation satellite system (GNSS) spoofing interference poses a great threat to the security of end users. Based on same propagation path characteristics signals transmitted by single antenna device, this paper proposes method against jamming utilizing Fréchet distance Doppler frequency difference. When receiver moves, data in window are fitted via leastsquares method, and between two is calculated obtain similarity evaluation value them. The detection signal carried out...

In this study, we conducted the activity, diversity, and density analysis of transposable elements (TEs) across five avian genomes (budgerigar, chicken, turkey, medium ground finch, zebra finch) to explore potential reason small genome sizes birds. We found that these exhibited low TEs by about 10% coverages diversity with TE landscapes dominated CR1 ERV elements, contrasting proliferation dynamics both between types species were observed genomes. Phylogenetic revealed clade was more diverse...

Abstract New genetic tools and strategies are currently under development to facilitate functional genomics analyses. Here, we describe an active member of the Tc1/mariner transposon superfamily, named ZB, which invaded zebrafish genome very recently. ZB exhibits high activity in vertebrate cells, range those widely used transposons piggyBac (PB), Sleeping Beauty (SB) Tol2. has a similar structural organization target site sequence preference SB, but different integration profile with...

We report the comprehensive analysis of Tc1/mariner transposons in six species neoteleost (cod, tetraodon, fugu, medaka, stickleback, and tilapia) for which draft sequences are available. In total, 33 families were identified these genomes, with 3-7 each species. Thirty full length designed as autonomous families, classified into DD34E (Tc1) DD×D (pogo) groups. The group was further five clusters (Passport-like, SB-like, Frog Prince-like, Minos-like, Bari-like). Within genomes cod, DNA...

Space object tracking and maneuver detection play an essential role in space situation awareness (SSA). The ordinary Kalman filter its variants may give large error due to the of object. In this paper, consistently track a maneuvering object, interacting multiple model (IMM) is utilized. Multiple Models with different process noise levels are used distinguish effects. IMM cubature (IMM-CKF) which considers geometric relations between based optical (SBO) sensor, sun. relation highly affects...

Since January 8, 2023, China has managed COVID-19 as a Class-B infectious disease, marking the epidemic's transition to low-level stage. This study analyzes relationship between public's perceived community with shared future for doctor-patient (PCSF), health self-consciousness, benefit finding, and anxiety in this Additionally, it compares changes these variables across different stages of COVID-19.

Although transposon-mediated enhancer trapping (ET) is successfully applied in diverse models, the efficiency of various transposon systems varies significantly, and little information available regarding by transposons zebrafish. Most potential enhancers (Ens) still lack evidence actual En activity. Here, we compared differences ET between sleeping beauty (SB), piggyBac (PB) Tol2 transposons. represented highest germline transfer efficiencies at 55.56% (NF0 = 165), followed SB (38.36%, NF0...

Intelligent navigation is a fundamental technology that enables unmanned systems to achieve autonomy in the intelligent era. However, existing schemes suffer from high computational complexity and power consumption, as well low robustness complex or unknown environments. To address these challenges, this paper proposes novel 3D brain-inspired simultaneous localization mapping (SLAM) method, called ORB-NeuroSLAM, based on oriented FAST rotated BRIEF (ORB) features. The proposed method takes...

We present an empirical investigation of 14 real world networks, which can be described by bipartite graphs. show that the basic elements (the actor nodes) in all networks cooperate and compete some acts (activities, organizations, or events). Each node is assigned a 'node weight', denotes obtained competition result. are interested distribution disparity weight propose three parameters for description. Firstly, empirically we observe total distributions systems may fitted so-called 'shifted...
