Commutativity of systems with their feedback conjugates [PDF]
Transactions of the Institute of Measurement and Control, 2018 After introducing commutativity concept and summarizing the relevant literature, this work is focused on the commutativity of feedback conjugates. It is already known that a linear time-varying differential system describing a single input-single output dynamical system is always commutative with its constant gain feedback pairs.

Conjugation Systems of IncT Plasmids [PDF]
Microbiology, 1985 Four IncT plasmids were compared for various characters, in particular pilus synthesis and function at different temperatures. The prototype Rts1 differed in some respects from the others (R402, R394, pIN25). At 37 degrees C, the supposedly temperature-sensitive conjugation systems of the plasmids could still function efficiently on a surface, but not ...

Star-Shaped Conjugated Systems [PDF]
Materials, 2010 The present review deals with the preparation and the properties of star-shaped conjugated compounds. Three, four or six conjugated arms are attached to cross-conjugated cores, which consist of single atoms (B, C+, N), benzene or azine rings or polycyclic ring systems, as for example triphenylene or tristriazolotriazine. Many of these shape-persistent [

The electronic structure of conjugated systems V. The interaction of two conjugated systems [PDF]
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1948 In this paper there is discussed the interaction of two conjugated systems across a conj ugated single bond. It is shown that the conjugation energy across the bond, and the mobile order of the bond, are both positive, and that both are closely related to the self-polarizabilities of the atoms forming the bond.

Conjugation in hydrogen-bonded systems [PDF]
Structural Chemistry, 2012 Analysis of the electron density distribution in clusters composed of hydrogen fluoride, water, and ammonia molecules, especially within the hydrogen-bond domains, reveals the existence of both σ- and π-binding between molecules. The σ-kind density distribution determines the mutual orientation of molecules.

, 2012 ISG15 is a ubiquitin-like modifier that is expressed in response to type 1 interferon signaling (IFN-α/β) and plays a role in antiviral responses. The core E1, E2, and E3 enzymes for ISG15 are Ube1L, UbcH8, and Herc5, respectively, and these are all also induced at the transcriptional level by IFN-α/β.

Evolution of Conjugation and Type IV Secretion Systems [PDF]
Molecular Biology and Evolution, 2012 Genetic exchange by conjugation is responsible for the spread of resistance, virulence, and social traits among prokaryotes. Recent works unraveled the functioning of the underlying type IV secretion systems (T4SS) and its distribution and recruitment for other biological processes (exaptation), notably pathogenesis.

A Property of Conjugated Systems [PDF]
Nature, 1941 IN a compound of the type X.(CH = CH)nY, the conjugated system is an electronic conductor between the covalent groups X and Y, and there must therefore be a correspondence between such chemical properties of the compound as leave the conjugated system intact and those of the covalent compound X. Y.

The ATG conjugation systems in autophagy
Current Opinion in Cell Biology, 2020 Autophagosome formation and maturation involve the two ubiquitin-like systems: The ATG8 and ATG12 systems. ATG8 (LC3s and gamma-aminobutyric acid receptor-associated proteins in mammals) and ATG12 are covalently conjugated to phosphatidylethanolamine and ATG5, respectively.
