FEBS Open Bio, EarlyView.Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

On the Conditions for the Characteristic Roots of a Matrix in a Sector
Journal of the Franklin Institute, 1983Abstract Davison and Ramesh expressed equivalently the condition for the characteristic roots of a real matrix to lie within a sector by the condition for a matrixof doubled order to be Hurwitzian (1). A further generalization of their result is given in this note.

Characteristic Ratio Symmetric Polynomials and Their Root Characteristics
International Journal of Control, Automation and Systems, 2021For a real polynomial p(s) = ansn + ⋯ + a1s + a0, its characteristic ratios are defined by $${\alpha _i}: = {{a_i^2} \mathord{\left/{\vphantom {{a_i^2} {{a_{i - 1}}{a_{i + 1}}}}} \right.\kern-\nulldelimiterspace} {{a_{i - 1}}{a_{i + 1}}}}$$ for i = 1, 2, ⋯,

Root temperature effect on hydraulic characteristics of roots in hydroponics
IFAC Proceedings Volumes, 1991ABSTRACT Water uptake and gas exchange in cucumber roots ( Cucumis sativus L. cv Chojitsu-Ochiai) were examined in a root temperature control system of air-tightened hydroponics. The effect of root temperature on water uptake rate was found in a sigmoidal pattern: The water uptake rate was reduced at root temperatures lower than 12°C.

CHARACTERISTICS OF ROOTS AND NODULATION IN LEGUMES
Madras Agricultural Journal, 1994A comparative study on the characteristics of root system was made between certain profusely nodulating and non-nodulating (21 legumes; 14 genera) to assess the influence of various factors on nodulation. There existed no relation between root hair or thinness of the root or reduction in the cortex and nodulation in these legumes.

Characteristic roots of quaternion matrices
Archiv der Mathematik, 1954In two recent publications [1], [2] it was shown that for matrices of (real) quaternion elements an eigenvalue theory can be developed similar to that for complex numbers. If A is such a matrix then quaternion elements λ and quaternion vectors x can be found such that Ax = xλ.

Characteristic Roots and Related Topics
1979The solutions of many problems in Applied Mathematics involve the so-called characteristic roots of a related matrix. Here we consider some of the important properties and concepts related to characteristic roots.
