The initiation of human pregnancy is marked by the implantation an embryo into uterine environment; however, underlying mechanisms remain largely elusive. To address this knowledge gap, we developed hormone-responsive endometrial organoids (EMO), termed apical-out (AO)–EMO, which emulate in vivo architecture tissue. AO-EMO comprise exposed apical epithelium surface, dense stromal cells, and a self-formed endothelial network. When cocultured with embryonic stem cell–derived blastoids,...
The aim of this work is to present a novel topology three-phase LLC converter with integrated magnetics. operation and the comprehensive theoretical analysis are presented; follows first harmonic approximation (FHA) approach simplify system model. Usually, achieves zero voltage switching (ZVS) as long it working in inductive region. Therefore, turn off losses considered main source converter. In paper design optimized minimize losses. On other hand, adapting three discrete transformer cores...
High-power piezoelectric characteristics under continuous driving were studied for lead-free ceramics of a textured bismuth layer-structured ferroelectric, (Sr0.7Ca0.3)2Bi4Ti5O18 + 0.2 wt % MnCO3 (abbreviated to HF-SCBT) and non-oriented specimen (OF-SCBT). The orientation the grains can improve their high-power properties such as vibration velocity, v0–p. value v0–p HF-SCBT ceramic exceeded 2.0 m/s at an applied electric field 3 V/mm short- long-time driving. We also observed that change in...
One of the key components for improving positioning accuracy global navigation satellite system (GNSS) is stability on-board microwave reference. Therefore, we have proposed a spaceborne photonic generator which composed frequency-stabilized laser and an optical frequency comb whose much higher than that currently-used rubidium atomic clocks. We use iodine-stabilized as reference down-converted to region by using without degradation [1]. A nonlinear amplifying loop mirror (NALM)-type...
For the next-generation Japanese global navigation satellite system, we have developed space borne highlystable microwave generation system by combination of an optical frequency reference and comb. A 1030-nm iodine-stabilized laser has been as whose stability reaches 10<sup>−14</sup> level at averaging time 2000 seconds. We a figure-8 type polarization maintaining (PM) fiber mode-locked light source for The repetition center wavelength our are 48.7 MHz 1560 nm, respectively, demonstrated...
Spaceborne precision frequency reference is one of the essential technologies for extensive applications in metrology, astronomy, remote sensing and global navigation satellite system, we have researched developed a high-precision microwave generation system which based on an optical reference.In our highly-stable generated from iodine-stabilized laser whose down-converted to region without degradation by using comb.The stability would reach 10 -15 level.In this conference, will mainly...
