The annual regrowth of deer antlers provides a valuable model for studying organ regeneration in mammals. We describe single-cell atlas antler regrowth. earliest-stage initiators were mesenchymal cells that express the paired related homeobox 1 gene ( PRRX1 + cells). also identified population “antler blastema progenitor cells” (ABPCs) developed from and directed process. Cross-species comparisons ABPCs several mammalian blastema. In vivo vitro displayed strong self-renewal ability could...
A chromosome-level giraffe genome assembly and gene-edited mice reveal molecular mechanisms underpinning its high stature.
Abstract Triploids are rare in nature because of difficulties meiotic and gametogenic processes, especially vertebrates. The Carassius complex cyprinid teleosts contains sexual tetraploid crucian carp/goldfish ( C. auratus ) unisexual hexaploid gibel carp/Prussian carp gibelio lineages, providing a valuable model for studying the evolution maintenance mechanism polyploids Here we sequence genomes two species assemble their haplotypes, which contain subgenomes (A B), to chromosome level....
Abstract Endothermy is a typical convergent phenomenon which has evolved independently at least eight times in vertebrates, and of significant advantage to organisms extending their niches. However, how vertebrates other than mammals or birds, especially teleosts, achieve endothermy not previously been fully understood. In this study, we sequenced the genomes two billfishes (swordfish sailfish), members representative lineage endothermic teleosts. Convergent amino acid replacements were...
The open-loop control of the stepper motor is simple, but it has low positioning accuracy, large torque pulsation, and energy efficiency. While closed-loop magnetic field oriented high small efficiency, problems such as complex structure amount calculation. This paper proposes a hybrid strategy using subdivision sensorless based on sliding mode observer (SMO) for speed respectively. Super-twisting SMO designed observe back electromotive force (back-EMF) implemented. Compared with traditional...
Two-phase hybrid stepper motors for aircraft are frequently used in electrically driven valves. Microstepping control is to improve the accuracy of motor. However, different decay modes affect efficiency, vibration and noise drive system. By analyzing mechanisms each mode, suitable models types motor proposed. The analysis results realize trade-off among microstepping noise.
Abstract Lungs, essential for terrestrial vertebrates and present in bony fishes but absent cartilaginous fishes, provide an ideal model studying organ origination. Our study analyzed single-cell RNA sequencing data from mature developing vertebrate lungs, revealing substantial similarities cell composition, developmental trajectories gene expression pattern across species. Notably, most lung-related genes are also indicating that presence alone does not guarantee lung development. We...
As the deepest vertebrate in ocean, hadal snailfish ( Pseudoliparis swirei ), which lives at a depth of 6,000–8,000 m, is representative case for studying adaptation to extreme environments. Despite some preliminary studies on this species recent years, including their loss pigmentation, visual and skeletal calcification genes, role trimethylamine N-oxide high-hydrostatic pressure, it still unknown how they evolved why are among few that have successfully adapted deep-sea environment. Using...

The striated frogfish (Antennarius striatus), a member of the sub-order Antennarioidei within order Lophiiformes, possesses remarkable adaptations. These include ability to modulate body coloration for camouflage, utilize bioluminescent esca predation, and employ elbow-like pectoral fins terrestrial locomotion, making it valuable model studying bioluminescence, adaptive fin-to-limb transition, walking-like behaviors. To better study contribute conservation frogfish, we obtained micro-CT...

This paper presents a comparative simulation and experimental studies, related to proportional plus integral (PI) fuzzy PI speed control in Brushless DC Motor (BLDCM) based on the dSPACE real-time system. The strategies have been designed MATLAB/Simulink implemented platform. on-line parameters debugged by ControlDesk. responses, obtained under control, both low high speed, are recorded compared for variety of operating conditions. Finally, experiment results verified feasibility validity schemes.
Protein crystallization is a process that very sensitive to the physical environment. Audible sound an environmental characteristic can significantly affect process. Previously, it was found result frequency dependent, is, of protein under different frequencies yields results. Here, we further investigate effect varying (or program) on crystallization. Twelve programs and six proteins were used test The results showed audible from high low exhibited most significant improvement in Varying...
It is relatively poorly understood how vertebrates can survive and thrive in deep-sea environments (depths below 3,000 m that are characterized by high hydrostatic pressures, low temperatures, sparse food resources). In this study, we compared the genomes of two eels (Ilyophis sp1 Ilyophis sp2 living m) against those shallow-water closely related other teleosts to examine genetic bases their adaptations deep-sea. Phylogenetic analyses showed these diverged from European ~111.9 million years...
