ROOT-N-CONSISTENT SEMIPARAMETRIC REGRESSION

, 1988
One type of semiparametric regression is b8X A u(Z), where b and u(Z) are an unknown slope coefficient vector and function. Estimates of b based on incorrect parametrization of u are generally inconsist ent, whereas consistent nonparametric estimates ...

The roots of nodulins

Physiologia Plantarum, 1990
Nodulin gene expression is an integral and highly specific part of the formation of nitrogen‐fixing nodules on the roots of leguminous plants. Dependent on the time of expression during root nodule development, nodulin genes can be divided into early and late nodulin genes.

ROOT RESORPTION

Australian Dental Journal, 1986
Abstract— Over the past years a great deal of work has been done in the field of tooth root resorption but notwithstanding this, understanding of the subject has progressed very little. This paper reviews the subject and suggests ways of minimizing root resorption or perhaps even eliminating it.

Salty Roots, Stunted Roots

Science, 2012
Plant Science![Figure][1] CREDIT: DIANE DIEDERICH/ISTOCK PHOTO Too much salt is as bad for plants as it is for us. For plants, salt stress and drought stress go hand in hand. Some of the more rapid responses to salt stress are signaled through actions of the sucrose nonfermenting ...

Root Growth and Rooting of Basswood

Botanical Gazette, 1968
Seedling root growth of basswood (Tilia americana L.) was observed in soil pits between nursery rows, in pots (by inverting the soil ball), and in Lucite cylinders in the greenhouse. Root growth occurred primarily during late spring, summer, and fall in the nursery. It occurred throughout the year in the greenhouse.

On generation of the root lattice by roots

Mathematical Proceedings of the Cambridge Philosophical Society, 2007
AbstractLet Φ be a root system and let Γ ⊆ Φ. In this short paper we prove that Γ contains a ${\mathbb Z}$-basis of the lattice that it generates.

Root Ecology and Root Physiology

1979
The rapid development of root research in the last few years is leading more and more to a specialization in this area of science. Root ecology and root physiology are now the two main fields in root research, as was made strikingly clear at the Second International Root Symposium 1971 in Potsdam (German Democratic Republic) under the title Ecology and
