Objective Morphometric data for the lumbar posterior longitudinal ligament (PLL) was investigated to identify whether there is a difference in the morphometry of the PLL of the lumbar spine at each level with respect to the pattern of intervertebral disc displacement. Methods In 14 formalin-fixed adult cadavers (12 males and 2 females), from L1 to L5, the authors measured the width and height...

PURPOSE To identify the genetic cause of isolated canine ectopia lentis, a well-characterized veterinary disease commonly referred to as primary lens luxation (PLL) and to compare the canine disease with a newly described human Weill-Marchesani syndrome (WMS)-like disease of similar genetic etiology. METHODS Genomewide association analysis and fine mapping by homozygosity were used to identif...

We performed a systematic screen for mutations affecting the trajectory of axons visualized by immunohistochemical staining of Medaka embryos with anti-acetylated tubulin antibody. Among the mutations identified, yanagi (yan) and kazura (kaz) mutations caused specific defects in projection of the posterior lateral line (PLL) nerve. In yan and kaz mutant embryos, the PLL nerve main bundle was mi...

The three-phase four-wire VSCs voltage source converters are used to connect sustainable sources the distribution system where loads predominantly single-phase. with unbalanced neutral has unwanted negative and zero sequence components. In this condition synchronism between VSC electrical grid that is done using PLL (Phase Locked Loop) affected. SRF-PLL (Synchronous Reference Frame-PLL) popular...

Engineered culture substrates with chemical neurite guidance cues have been used for studying the mechanism of axon pathfinding at cellular level. In this study, we designed a novel poly-l-lysine (PLL) micropattern ("pinstripe micropattern") to investigate how the same biomolecules with slightly different surface concentration can affect in vitro neuronal growth. The pinstripe micropattern was ...

In this paper, an adaptive version of the impedance-conditioned phase-locked loop (IC-PLL), namely IC-PLL (AIC-PLL), is proposed. The has recently been proposed to address issue synchronisation with a weak AC grid by supplementing conventional synchronous reference frame (SRF-PLL) additional virtual impedance term. resulting aims synchronise converter remote and stronger point in grid, hence in...

In this paper, a review of Phase Locked Loop (PLL) algorithms and symmetrical component extraction methods intended for grid-connected power electronic converters are presented. Proposed classification is based on voltage representation in three coordinates: natural (abc), stationary (αβ) and rotating coordinates (dq). The three selected algorithms are described in details: Dual Second Order Ge...

This study describes the previously unreported intrinsic capacity of poly-L-lysine (PLL) sixth generation (G(6)) dendrimer molecules to exhibit systemic antiangiogenic activity that could lead to solid tumor growth arrest. The PLL-dendrimer-inhibited tubule formation of SVEC4-10 murine endothelial cells and neovascularization in the chick embryo chick chorioallantoic membrane (CAM) assay. Intra...

The CMOS PLL based Frequency Synthesizer is a vital role in Receiver front end Sub component. The main objective of this paper is to design a high frequency of oscillation, less phase noise and power efficient PLL. In general, the PLL contains PFD, Loop Filter, VCO and Frequency Divider. The VCO is a critical component in Phase Locked Loop for low power CMOS designs. Here the Source Coupled VCO...

We describe the global optimization of phaselocked loop (PLL) circuits using geometric programming (GP). Equations for the jitter, frequency range, and power of the PLL are presented in GP form. An array of PLL circuits was automatically generated using this technique in a , CMOS process. Silicon measurements show good agreement with the model. The results include a PLL with a period jitter of ...
