Hematopoietic stem cells (HSC) maintain lifelong hematopoiesis. However, in current clonal analyses with unbiased “barcoding” approaches, steady-state hematopoietic clones young and middle-aged adults rarely have detectable HSCs, which precludes comprehensive interrogation of HSC behaviors. In the study, we used previously described Sleeping Beauty transposon model to investigate self-renewal differentiation at a level following chase that significantly enriched HSC-derived clones. From...

A resistive-type dc superconducting fault current limiter (SFCL) is developed for the limiting at Suzhou Nami substation. The rated voltage and are 20 kV 400 A, respectively. prospective peak value of short-circuit about 3.5 kA, could be limited to less than 2.1 kA by SFCL. SFCL uses 1800-m stainless steel reinforced yttrium barium copper oxide (YBCO) conductor. According testing results, has passed withstand test 50 kV/min, full-wave lightning impulse 95 kV, power switching with a 2.26...

The arthropod communities are influenced by both local conditions and features of the surrounding landscape. Landscape complexity stand factors may influence in poplar forests, but multiscale effects these on defoliators natural enemies still poorly understood. We collected arthropods at 30 sampling sites within five forest landscapes Xinjiang, China, assessed whether landscape species abundance diversity arthropods. was quantified several independent metrics composition, configuration,...

Ultracapacitors (UCs), with their features of high power density and current charge-discharge, have become the best choice for dynamic compensation to improve stability microgrids are increasingly being applied in microgrids. This paper presents control an energy storage system (ESS) based on ultracapacitors context grid-connected The ESS is composed DC/AC DC/DC converters tied by a dc link. An improved model proposed. Based proposed Proportional-Integral-Resonant (PIR) DC link voltage...

In order to retrain chaotic oscillation of marine power systems which are excited by periodic electromagnetism perturbation, in this paper, a novel model free backstepping control methods designed.First, the dynamic system is established based on two parallel nonlinear model.Then, extended state observer (ESO) designed estimate velocity signal and unknown function.Next, controller proposed ESO.Finally, simulation results demonstrate algorithm can quickly oscillation.And it shows method...

Abstract Fusion and fission are two important phenomena that have been experimentally observed in many real physical models. In this paper, we investigate the (2+1)-dimensional Hirota–Satsuma–Ito equation via physics-informed neural networks (PINN) method. By choosing suitable physically constrained initial boundary conditions, data-driven fusion solutions obtained for first time. Dynamical behaviors error analysis of these investigated illustratively numerical figures, which show good...

The modular multilevel converter (MMC) had shown great value in HVDC systems. One of the major obstacle that limited usage MMC multi-terminal systems (MTDC) is DC fault handling method. To minimize impact faults MTDC, circuit breakers (HVDC CBs) was a preferred choice. Due to dc current breaking capability, CBs combined with superconducting limiters (SFCLs) potential solution. For MMC-MTDC and SFCLs, this paper proposed side main parameters selection This method included for selecting...

Then, introduced basic principle resistive SFCLs inductive their effect limiting current. Based main...

Voltage stability problem is one of the most significant problems faced by grid-connected operation wind farms. Traditionally, each farm adjusts its reactive power and voltage independently, which can not be able to optimize regional grid dispatching. In order improve operating economy connected with medium or large-scale farms, this paper presents a coordination optimization model satisfy management group. To solve multi-objective problem, particle swarm algorithm was adopted for fast...
