In this article, we present a virtual control contraction metric (VCCM) based nonlinear parameter-varying approach to design state-feedback controller for moment gyroscope (CMG) track user-defined trajectory set. This VCCM (NL) stabilization and performance synthesis approach, which is similar linear (LPV) approaches, allows achieve exact guarantees of exponential stability -gain on NL systems ...
The initiation of eukaryotic DNA replication is a highly regulated process conserved from yeast to human. The past decade has seen significant advances in understanding how the CMG (Cdc45‐MCM‐GINS) replicative helicase is loaded onto DNA. However, very little was known on how this complex is removed from chromatin at the end of S phase. Two papers in a recent issue of Science [1], [2] show that...
FinFET and UTBSOI (or ETSOI) FET are the two promising multi-gate FET candidates for sub-22nm CMOS technology. The BSIM-CMG and BSIM-IMG are the surface potential based physical compact models for multi-gate MOSFETs. The BSIM-CMG model has been developed to model common symmetric double, triple, quadruple and surround gate MOSFET. The BSIM-IMG model has been developed to model independent doubl...
Lack of effective therapy is a major problem in the treatment of pancreatic cancer. In the present study, we investigated a natural product, the extract of Pao Pereira (Pao), for its anti-pancreatic cancer effect in vitro and in vivo, either alone or in combination with the first-line chemotherapeutic drug gemcitabine (Gem). Pao induced dose-dependent apoptosis to all five tested pancreatic can...
In eukaryotes, although theMcm2-7 complex is a key component of the replicative DNA helicase, its association with Cdc45 and GINS (the CMG complex) is required for the activation of the DNA helicase. Here, we show that the CMG complex is localized to chromatin in human cells and describe the biochemical properties of the human CMG complex purified from baculovirus-infected Sf9 cells. The isolat...
Clinical metagenomics (CMg), referred to as the application of next-generation sequencing (NGS) to clinical samples, is a promising tool for the diagnosis of hospital-acquired pneumonia (HAP). Indeed, CMg allows identifying pathogens and antibiotic resistance genes (ARGs), thereby providing the information required for the optimization of the antibiotic regimen. Hence, provided that CMg would b...
In eukaryotic DNA replication initiation, hexameric MCM (mini-chromosome maintenance) unwinds the template double-stranded DNA to form the replication fork. MCM is activated by two proteins, Cdc45 and GINS, which constitute the 'CMG' unwindosome complex together with the MCM core. The archaeal DNA replication system is quite similar to that of eukaryotes, but only limited knowledge about the DN...
DNA replication licensing is now understood to be the pathway that leads to the assembly of double hexamers of minichromosome maintenance (Mcm2-7) at origin sites. Cell division control protein 45 (Cdc45) and GINS proteins activate the latent Mcm2-7 helicase by inducing allosteric changes through binding, forming a Cdc45/Mcm2-7/GINS (CMG) complex that is competent to unwind duplex DNA. The CMG ...
Overactive bladder (OAB) can be caused by a variety of conditions. We believe that cystometrography (CMG) is an essential part of the diagnostic evaluation, both in defining underlying pathophysiology and directing treatment. Essential to the diagnosis of OAB syndrome is some combination of urinary frequency, urgency, urge incontinence, and pain. CMG can be thought of simply as a provocative te...
Control moment gyros (CMGs) are spacecraft attitude control actuators which act as torque amplifiers. They are thus suitable for attitude hold and reorientation of large spacecraft or for slew maneuvering. They provide the necessary torques via gimballing a spinning flywheel. A major problem encountered with the use of CMGs in practice is the possibility of singularities for certain combination...
