Study of the control-equilibrium of control systems
Journal of Systems Engineering and Electronics, 2008 Abstract Not so much had been talked about equilibrium in control area. On the basis of the phenomenon of balance, the concept of control-equilibrium and control-equilibrium of a control system is proposed. According to this theory, a perfect control method should not only guarantee stability of the system, but also ensure the control-equilibrium of ...

Control of self-organization: From equilibrium to non-equilibrium
Acta Physica Sinica, 2020 Self-organization represents a ubiquitous transition from disorder to order. It plays a critical role in forming crystalline materials and functional structures in biology. Functional structures are generally hybrid on a multiple scale in which nano-structures are often organized in a specific way such that they can perform functions.

A design approach for feedback-feedforward control systems
, 2010 In this paper, a general design approach based on the concept of ‘Control Equilibrium Point’ is proposed to derive the feedforward control law in feedback-feedforward control systems.

Is the forest biomass a key regulator of global warming?: A mathematical modelling study
Geology, Ecology, and Landscapes, 2022 In this article, a mathematical model has been formulated by considering forest biomass and global warming as a separate compartment. It is assumed that the forest biomass follow logistic growth in the absence of global warming.

Equilibrium mechanism between dc voltage and ac frequency for ac–dc interlinking converters
iEnergy, 2022 The equilibrium between dc bus voltage and ac bus frequency (Udc-f equilibrium) is the algorithm core of unified control strategies for ac-dc interlinking converters (ILCs), because the equilibrium implements certain mechanism.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Hardy–Weinberg equilibrium and control subjects [PDF]
Kidney International, 2006 To the Editor: Consider a gene locus with two alleles, 'A' and 'a'. The frequency of allele 'A' will be designated by p and that of allele 'a' by q. Hardy and Weinberg showed that in a very large population with random mating, the frequencies of AA, Aa, and aa genotypes are p2, 2pq, and q2, respectively.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
