Understanding the molecular and cellular mechanisms of human primordial germ cells (hPGCs) is essential in studying infertility cell tumorigenesis. Many RNA-binding proteins (RBPs) non-coding RNAs are specifically expressed functional during hPGC developments. However, roles regulatory these RBPs RNAs, such as microRNAs (miRNAs), hPGCs remain elusive. In this study, we reported a new function DAZL, cell-specific RBP, miRNA biogenesis proliferation. First, DAZL co-localized with let-7a PGCs...
RNA secondary structures comprise double-stranded (ds) and single-stranded (ss) regions. Antisense peptide nucleic acids (asPNAs) enable the targeting of ssRNAs weakly formed dsRNAs. Nucleobase-modified dsRNA-binding PNAs (dbPNAs) allow for dsRNA targeting. A programmable RNA-structure-specific strategy is needed simultaneous recognition dsRNAs ssRNAs. Here, we report on combining dbPNAs asPNAs (designated as daPNAs) dsRNA-ssRNA junctions. Our data suggest that traditional asPNA (with a...
The need to implement wastewater reuse in Beijing is discussed. Based on the investigation of built projects Beijing, differences between small system and large systems were analyzed according technical, economical social issues. advantages disadvantages then given. In planning urban region, was adopted. rations reclaimed water for difference land use type, including industrial reuse, municipal grass irrigation, scenes determined. Then information every block central using GIS techniques,...
This paper presents a self-centring bridge pier system connected by unbonded post-tensioned tendons and mild steel which can minimize the post-earthquake residual deformation displays stable energy dissipate capacity.The basic mechanical concept of is explained.Referring to quasi-static test,a simplified model finite element herein illustrated,considering flexural deformation,unbonded length strain penetration due differences between bar concrete within connection member.To solve stress...
A self-centring bridge pier is a combination of elastic recovery devices and internal or external energy dissipaters. During the cyclic loading test, it proved that system can minimize residual drift whereas holding sufficient dissipate capacity as well bearing capacity. It worth noting simplified analytical model proposed based on experimental response regarding flexural deformation, unbounded length mild steels strain penetration. Comparison between test results has indicated reasonable...
Wireless smart sensor networks (WSSN) have many advances compared with traditional structural health monitoring (SHM) such as wireless process, real-time calculation and low cost. However power consumption is considered one of the most limitations in this field. The unique features offered by decentralized data aggregation (DDA) technique potential to overcome enable implementation dense array WSSN on large structures. This paper presents a system identification simply supported plate based...
Summary RNA secondary structures comprise double-stranded (ds) and single-stranded (ss) regions. Antisense peptide nucleic acids (asPNAs) enable the targeting of ssRNAs weakly formed dsRNAs. Nucleobase-modified dsRNA-binding PNAs (dbPNAs) allow for relatively stable A programmable structure-specific strategy is needed simultaneous recognition dsRNAs ssRNAs. Here, we report on combining dbPNAs asPNAs (designated as daPNAs) dsRNA-ssRNA junctions. Our binding modeling data suggest that...
Structural signal is taken self-adaptive decomposition by Hilbert-Huang Transform mainly composed of the EMD(empirical mode decomposition) and HT(Hilbert Transform), which especially suitable for structural projects in non-linear, non-stationary analysis through local characteristic. However, some weak may be ignored EMD resulting modal missing. Butterworth filter an electronic designed to have flat frequency response. Considering influence noise , band pass are applied together process...
The original concept of self-centering system was first proposed under the PRESSS research project in 1991 UC San Diego. particularly promising and effective structural solution initially defined as hybrid literature then recently. In ductile connection system, inelastic demand is accommodated through opening closing (control rocking) a pre-existing gap at critical interface, with no consequent damage such plastic hinges traditional elements. This paper provides an overview recent advances...
The pre-stressed stainless steel wire mesh (SSWM) –mortar (M) is a laminate structure for structural strengthening and rehabilitation. Pre-stressing the key technology engineering practice. A jogged anchor proposed anchoring large diameter SSWM conveniently. flexural performances of 5 damaged RC beams strengthened by SSWM-M one referential beam were tested. experimental results indicates that has better performance in controlling crack growth, restoring capacity stiffness than small SSWM-M.
We use the distributed cohesive element method to simulate dynamic fracture in structural specimen and arbitrary crack path is predicted. The focus on convergence of as an approximation real spatial characteristic mesh size h approaches zero. propose structured satisfactory capturing shape we refine because Hausdorff distance converges. However, length does not converge refined. There a finite deviation between predicted physically mesh.
A novel quantitative shadow testing equipment is presented based on the digital imageprocessing technique for characterizing local surface deformations optical surface. Two magnetic stepping motors control positions of knife-edge cutting wave-front reflected back from aspheric separately. At each position blocking image focal plane, it recorded and analyzed by an image-processing set-up behind under computer control. Based a group images recorded, analysis slopes performed picking up...
A new model developing knife-edge test to a quantified method is built in this paper. Based on and image-processing technology, the local surface deformations aspheric can be characterized. The image-receiver CCD (756x504) assure that deformation little curved face measured detected sensitively. For reducing influence of vibration optical image-receiving subsystems offset images, least-squares procedure has been used process images for three times. Then all will cut at circles moved same...
