Nonparallelism of cambium cells in neighboring rows

Acta Societatis Botanicorum Poloniae, 2014
The periclinal walls of cambial cells in neighboring lineages (rows) may not be parallel when viewed in their radial aspect. This lack of longitudinal parallelism may be so extensive that in active cambium pairs of cells from neighboring rows may be in ...

SUGAR TRANSPORT AND STORAGE IN THE PHLOEM OF BETULA PENDULA ROTH VAR. PENDULA AND VAR. CARELICA

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015
We have previously hypothesized that the cause of figured wood formation in Karelian birch (Betula pendula Roth var. carelica) is excessive sucrose supply to the phloem and the cambial zone.

Fluctuation Dynamics in US Interest Rates and the Role of Monetary Policy [PDF]

This paper presents empirical evidence suggesting that the degree of long-range dependence in interest rates depends on the conduct of monetary policy. We study the term structure of interest rates for the US and find evidence that global Hurst exponents
