The response of Liriope, Hosta, and Hedera to sunlight and fertilization

The purpose of this investigation was to study the response of three different species of ground covers, Liriope, Hosta, and Hedera to various degrees of shade and levels of nitrogen and potassium. The plants were grown in pots under three light conditions: full sunlight, half of full sunlight, and a quarter of full sunlight. Two levels of nitrogen and po-tassium, high and low, were applied at the beginning of this experiment. Data for this study included height, fresh and dry weights, number of leaves or shoots, chlorophyll and starch content. Height and number of leaves of these three ground covers were significantly affected by light and nitrogen treatment. In most cases, the reduction of light and a high nitrogen level produced better growth and better ap-pearing plants than were obtained under full sunlight and low nitrogen fertilization. Differences due to potassium levels were usually non-significant

Fermionic phase transition induced by the effective impurity in holography

We investigate the holographic fermionic phase transition induced by the effective impurity in holography, which is introduced by massless scalar fields in Einstein-Maxwell-massless scalar gravity. We obtain a phase diagram in $(\alpha, T)$ plane separating the Fermi liquid phase and the non-Fermi liquid phase.Comment: 17 pages, 9 figure

A Note on Symplectic, Multisymplectic Scheme in Finite Element Method

We find that with uniform mesh, the numerical schemes derived from finite element method can keep a preserved symplectic structure in one-dimensional case and a preserved multisymplectic structure in two-dimentional case in certain discrete version respectively. These results are in fact the intrinsic reason that the numerical experiments indicate that such finite element algorithms are accurate in practice.Comment: 7 pages, 3 figure
