Axon regeneration is arrested in the injured central nervous system (CNS) by axon growth-inhibitory ligands expressed in oligodendrocytes/myelin, NG2-glia, and reactive astrocytes in the lesion and degenerating tracts, and by fibroblasts in scar tissue. Growth cone receptors (Rc) bind inhibitory ligands, activating a Rho-family GTPase intracellular signaling pathway that disrupts the actin cyto...

Passive cooling is inevitable for buildings to be resilient global warming. While many forms of passive techniques have been developed, radiative (RC), as an emerging technology, still not widely applied in buildings. Due current limitations, proposals implementing RC come up combination with other design strategies. In this study, we propose combine natural ventilation the form a novel RC-enha...

This paper describes a real-time control system implemented on the RC 4000 computer with an internal store of 4096 words. The system permits a number of independent programs to be executed periodically on a time-sharing basis. The first version of the system performs supervisory control of the ammonium nitrate plant Pulawy II in Poland. After a description of the Pulawy system, the choice of a ...

Abstract. Prediction of spatiotemporal chaotic systems is important in various fields, such as numerical weather prediction (NWP). While data assimilation methods have been applied NWP, machine learning techniques, reservoir computing (RC), recently recognized promising tools to predict systems. However, the sensitivity skill machine-learning-based imperfectness observations unclear. In this st...

During pre-replication complex (pre-RC) formation, origin recognition complex (ORC), Cdc6, and Cdt1 cooperatively load the 6-subunit mini chromosome maintenance (MCM2-7) complex onto DNA. Loading of MCM2-7 is a prerequisite for DNA licensing that restricts DNA replication to once per cell cycle. During S phase MCM2-7 functions as part of the replicative helicase but within the pre-RC MCM2-7 is ...

This study mainly focuses on the design of an autonomous remote control (RC) hovercraft. In the control design of hovercraft, we apply a fuzzy gain scheduled integral scheme to deal with the uncertainties of nonlinear system. In the implement system, the BASIC Stamp micro-controller is applied as control center to perform tasks. In addition, the ultrasonic sensor is used for providing the funct...

Photosystem II (PSII) of photosynthesis has the unique ability to photochemically oxidize water. Recently an engineered bacterioferritin photochemical 'reaction centre' (BFR-RC) using a zinc chlorin pigment (ZnCe6) in place of its native heme has been shown to photo-oxidize bound manganese ions through a tyrosine residue, thus mimicking two of the key reactions on the electron donor side of PSI...

This paper studies repetitive control (RC) with linear phase lead compensation to precisely track periodic trajectories in piezo-based scanning probe microscopes (SPMs). Quite often, the lateral scanning motion in SPMs during imaging or nanofabrication is periodic. Dynamic and hysteresis effects in the piezoactuator cause significant tracking error. To minimize the tracking error, commercial SP...

objectives: different chelators may be used during root canal treatment, offering various advantages including lubricant effect inside the canal and smear layer removal. however, chelator residues in narrow root canals can lead to apical microleakage. the aim of this in-vitro study was to compare apical microleakage following the use of three root canal chelators via fluid filtration method in ...
