In Arabidopsis, the EMBYRONIC FLOWER2 (EMF2), VERNALISATION2 (VRN2) and FERTILISATION INDEPENDENT ENDOSPERM2 (FIS2) genes encode related Polycomb-group (Pc-G) proteins. Their homologues in animals act together with other Pc-G proteins as part of a multimeric complex, Polycomb Repressive Complex 2 (PRC2), which functions as a histone methyltransferase. Despite similarities between the fis2 mutan...

Cardiotrophin-like cytokine:cytokine-like factor-1 (CLC:CLF-1) is a heterodimeric neurotropic cytokine that plays a crucial role during neuronal development. Mice lacking CLC:CLF-1 die soon after birth due to a suckling defect and show reduced numbers of motor neurons. Humans carrying mutations in CLC:CLF-1 develop similar disorders, known as Sohar-Crisponi or cold-induced sweating syndrome, an...

Cell-based therapies (CBTs) are considered the effective approaches to treat liver failure. However, which cell type is the most suitable source of CBTs for acute liver failure (ALF) or chronic liver failure (CLF) remains unclear. To investigate this, mature hepatocytes in adult liver (adult HCs), fetal liver cells (FLCs), induced hepatic stem cells (iHepSCs) and bone marrow derived mesenchymal...

In this paper, we present a novel model predictive control (MPC) scheme that incorporates stability information derived from a control Lyapunov function (CLF) to dynamically prune suboptimal sequences from the search space and decrease the computational burden placed on the controller. The CLF used for pruning is then incorporated into a cost function that penalizes energy in the error system a...

In this paper, the control Lyapunov function (CLF) approach is adopted to investigate finite-time attitude of rigid spacecraft subject parameter uncertainty and external disturbance. By using an extended state observer estimate disturbance, a CLF controller proposed for stabilization system. The designed includes two parts. first part classical based controller, which ensure globally asymptotic...

We study the stability of an equilibrium arbitrarily switched, autonomous, continuous-time systems through computation a common Lyapunov function (CLF). The switching occurs between finite number individual subsystems, each which is assumed to be linear. present linear programming (LP) based approach compute continuous and piecewise affine (CPA) CLF compare this with different methods in litera...

This paper2 considers feedback design for nonlinear, multi-input affine control systems with disturbances. It studies the problem of assigning, by choice of feedback, a desirable upper bound to a given control Lyapunov function (clf) candidate's derivative along closed-loop trajectories. Specific choices for the upper bound are motivated by C2 and C, disturbance attenuation problems. The main r...

The edge computing node plays an important role in the evolution of artificial intelligence-empowered Internet things (AIoTs) that converge sensing, communication, and to enhance wireless ubiquitous connectivity, data acquisition, analysis capabilities. With full issue security new cloud-edge-terminal network hierarchy AIoTs comes fore, for which blockchain technology is considered as a potenti...

In the title compound, C(17)H(13)ClF(2)O(3), a multifunctional aromatic compound, the dihedral angle between the two benzene rings is 51.8 (3)°.

This paper deals with an inverse optimal H1 disturbance attenuation for the planar manipulators with the eye-in-hand system. The input-to-state stability control Lyapunov function (ISS-CLF) is constructed the full Lagrangian dynamics based on a potential function of the image feature parameter space. The ISS-CLF gives us an inverse optimalH1 control law. A proposed controller solves the inverse...
